They are the general trend for Intelligent construction equipment and network data calculation

At present, intelligent construction machinery is one of the main research directions of major manufacturers and research institutions. There are many technical obstacles in the research and development process, and there is a long way. According to bauma Munich, topics related to intelligent construction and connected data computing will be the focus of industry discussion in 2022.

In order to achieve partial automation in more complex construction machinery construction sites, it is essential that different brands of equipment can communicate data and information to each other. To this end, the German association of machinery and equipment manufacturing industry and Germany are actively promote construction industry association, in order to make future construction site to more self-independence of digital, intelligent and way of operation and management, from the most basic equipment “starting/stopping” began, the running status of equipment and so on all need to implement standardization of data information. This cross-machine collaboration allows construction operations to multi-task in parallel and, ideally, cut construction time in half.

Cause analysis and troubleshooting of failure of bulldozer steering when working

Bulldozer is a kind of mechanical equipment commonly used in the construction site of infrastructure construction, due to long-term high load operation combined with the impact of the bad working environment, a long time will be, bulldozer opportunity can not turn, turn difficult, cold car can turn hot car can not turn (transmission part of the oil temperature rise to the working temperature) fault phenomenon. So, what happened when the bulldozer couldn’t turn when it was working? The first is to analyze the cause of the failure and then make targeted troubleshooting.

bulldozer

1. The cause of the fault

At this time, the overflow valve at the inlet of the directional control valve assembly can be removed and checked. The reason is that the oil is too dirty, the impurities in the oil are worn or strained overflow spool and valve body surface, so that the spool is stuck in the position of opening and connecting the oil back, losing the adjustment of the oil pressure, so that the system pressure can not reach the standard value.

2. Troubleshooting and processing

Check the parts after the relief valve is disassembled. If the damage is not serious, fine emery cloth or sandpaper can be used to repair and grind the surface of the damaged parts. Replace parts if they are badly damaged. In the repair at the same time must replace the oil (or filter) and fine filter element and clean the coarse filter element.

What are the faults of crawler bulldozer that can’t walk normally?

During routine work, the crawler bulldozer failed.For example, walking errant, not walking, fast block walking errant and other problems, among which walking errant is one of the common fault phenomena of crawler bulldozer, such faults are usually related to the walking motor, crawler and hydraulic pump and other components.

First, the caterpillar bulldozer running deviation fault

1. The bulldozer runs off track

2. The bulldozer quickly blocks the running deviation

Second, crawler bulldozer inspection sequence

bulldozer

1. Walking and running sideways

(1) Check the track, measure the tension of the left and right sides of the track the same, eliminate the track fault.

(2) When the crawler bulldozer is operated in a straight line, the result is also off-track, thus the fault of the main hydraulic pump can be eliminated.

(3) Forward and backward are running in the same direction, so the oil seal fault of the central rotary joint can be eliminated.

(4) Measure the pressure of the walking motor on both sides. The pressure on one side is 28Mpa, and the pressure on the other side is 34Mpa.

(5) The main safety valve is suspected to fail because of the different pressure of the two sides of the walking motor.After further inspection and analysis, it is found that the spring in the main safety valve absorbs the temperature of hydraulic oil in the operation process, which leads to the temperature rise and the elastic force decrease, resulting in the decrease of the original set pressure of the side walking motor, and finally leads to the deviation of the crawler bulldozer.After replacing the spring of the main safety valve to make the pressure of both sides of the walking motor equal, the equipment operation will return to normal.

2. Fast block walking deviation

Check the hydraulic main pump.

The fault of the main hydraulic pump can be ruled out because the working device of the crawler bulldozer (arm, bucket rod and bucket) and the rotary device are all working

Prevention of cavitation failure of hydraulic cylinder in construction machinery

When we repair the hydraulic cylinder of construction machinery, we can see the inner wall of the hydraulic cylinder, the piston or the piston rod surface has some honeycombed holes, which are caused by cavitation.The harm of hydraulic cylinder cavitation is quite large, it will lead to the black surface, and even the phenomenon of supporting ring and sealing ring burning, resulting in the internal leakage of the hydraulic cylinder.When cavitation and other types of corrosion work together, it will accelerate the corrosion speed of the main parts of the hydraulic cylinder several times or even dozens of times, so as to seriously affect the normal use of construction machinery.Therefore, it is very necessary to prevent the cavitation of hydraulic cylinder.


(1) strictly close the selection of hydraulic oil
(2) prevent the oil temperature from being too high and reduce the hydraulic impact
(3) keep the normal clearance of the joint surface of the hydraulic components
(4) pay attention to the exhaust during maintenance
