Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a maintenance platform for construction machinery. Background Art

[0002] During the use of construction machinery and equipment, regular inspections and repairs are required. The quality of the inspection and repair work is directly related to the service life of the construction machinery and equipment. For some construction machinery with not very heavy weight and not very large volume, during maintenance, the staff first lift the construction machinery by a large lifting platform, and then perform maintenance operations on the bottom of the construction machinery; for other parts of higher machinery;

[0003] However, for large machinery with relatively heavy weight, the large lifting platform cannot lift the machinery and equipment. For construction machinery with relatively large volume, due to its large volume, the large lifting platform cannot hold the equipment, so it is not convenient to lift the equipment. For such engineering equipment, it is necessary for the staff to enter the bottom of the construction machinery to repair the equipment. During the repair, the repair personnel generally lie on the ground at the bottom of the construction machinery or squat halfway, which is very inconvenient;

[0004] Therefore, in view of the above-described technical problems, there is an urgent need for a maintenance platform for construction machinery. Content of the Utility Model

[0035] Combined with the attached Figure 1-9 , a maintenance platform for construction machinery, comprising:

[0036] An underframe 100 and a hydraulic shear lift table 200, the hydraulic shear lift table 200 is arranged inside the underframe 100; used to carry construction machinery components to be repaired or maintenance personnel;

[0037] Universal wheels 101 are provided at the positions of the four corners at the lower end of the underframe 100, facilitating the flexible movement of the platform on different ground surfaces. Bottom electric hydraulic cylinders 102 are symmetrically provided on both sides at the lower end of the underframe 100, and a bottom pad 116 is provided at the lower end of the bottom electric hydraulic cylinders 102; its expansion and contraction are controlled by the controller 104, so that the bottom pad 116 supports on the ground, reducing the pressure on the ground and preventing sliding, and making the universal wheels 101 leave the ground, which can enhance the stability of the platform and can support heavier items;

[0038] A battery 103 is arranged inside the underframe 100 to provide power support for electric components such as the bottom electric hydraulic cylinders 102 and the end electric hydraulic cylinders 201. A controller 104 is arranged inside the underframe 100, responsible for receiving signals from the remote control receiver 105 and controlling the actions of each electric component. The remote control receiver 105 is arranged above the controller 104; enabling maintenance personnel to accurately control the platform and improving the operation efficiency

[0039] It further includes a remote control 300, and the remote control 300 cooperates with the remote control receiver 105;

[0040] One end of the platform of the hydraulic shear lift table 200 is provided with an end electric hydraulic cylinder 201. A round hole 202 is provided at the upper end of the end electric hydraulic cylinder 201. An adjusting bolt 203 is arranged in the round hole 202. A supporting plate 204 is provided at the upper end of the end electric hydraulic cylinder 201. Connecting ears 205 are symmetrically arranged at the lower end of the supporting plate 204. The connecting ears 205 are rotationally connected to the end electric hydraulic cylinder 201 through the adjusting bolt 203. A headrest 206 is arranged at the upper end of the supporting plate 204. After the head of the repairer rests on the headrest 206, it will support the head, making the neck of the repairer more comfortable. There is no need to lift the head with force by the neck, providing a comfortable leaning environment for the head of the repair personnel. Moreover, the supporting plate 204 can be tilted and adjusted to meet the adjustment needs of different angles of the head of the repairer.

[0041] One end of the chassis 100 is symmetrically provided with sleeves 106. A handle 107 is arranged at one end of the chassis 100. The lower end of the handle 107 is located inside the sleeve 106, which is convenient for manually pushing the platform.

[0042] A limit ring 108 is arranged at the lower end of the handle 107 to prevent the handle 107 from being inserted too far into the sleeve 106.

[0043] The middle part of the lower end of the chassis 100 is symmetrically provided with U-shaped sliding rails 109. One end of one of the U-shaped sliding rails 109 is provided with a first baffle 110, and one end of the other U-shaped sliding rail 109 is provided with a second baffle 111. The first baffle 110 and the second baffle 111 are respectively located on both sides of the chassis 100. A placing plate 112 is slidably arranged in the U-shaped sliding rail 109. Sliding grooves 113 are symmetrically arranged on both sides of the placing plate 112. The sliding grooves 113 are slidably matched with one of the corresponding first baffle 110 and the second baffle 111.

One end of the other sliding groove 113 is provided with a second limiting plate 115. The second limiting plate 115 is matched with the second baffle 111 to limit the placing plate 112. The placing plate 112 can be pulled out from both sides of the chassis 100 as a tool storage table when needed. When pulled out to the left, the first limiting plate 114 will abut against the first baffle 110, which can prevent the placing plate 112 from being completely pulled out of the U-shaped sliding rail 109. When pulled out to the right, the second limiting plate 115 will abut against the second baffle 111, which can prevent the placing plate 112 from being completely pulled out of the U-shaped sliding rail 109.

[0044] When the present utility model is specifically implemented,

[0045] During use, pull out the placement board 112, place the toolbox on the placement board 112, and then the maintenance worker can lie on the hydraulic shear lift table 200. Then, rest the head on the headrest 206. The adjustment bolt 203 can be loosened in advance. After the head is rested on the headrest 206, the headrest 206 can be rotated by pushing it forward and backward with the head to adjust the angle of the headrest 206. Then, step on the ground with both feet and push the maintenance platform under the construction machinery to repair the bottom of the construction machinery.

[0046] When the height is insufficient, the maintenance worker can control the hydraulic shear lift table 200 to rise through the remote control 300, and the maintenance worker will be lifted up. Stop when reaching the appropriate position.

[0047] When adjusting the height of the headrest 206, the maintenance worker can control the end electric hydraulic cylinder 201 to upgrade through the remote control 300, and then adjust the height of the headrest 206.

[0048] When it is necessary to lift heavier components, first place the components on the hydraulic shear lift table 200, and then the worker pushes the maintenance platform to the designated position. After reaching the designated position, the bottom electric hydraulic cylinder 102 can be controlled to rise through the remote control 300, so that the bottom pad 116 supports on the ground and the universal wheels 101 leave the ground to reduce the pressure on the ground and prevent slipping.

[0049] When it is necessary to repair the construction machinery at a high place, the maintenance personnel can also stand on the hydraulic shear lift table 200, and then the hydraulic shear lift table 200 drives the maintenance personnel to rise to reach the repair position for repair.

[0050] According to the usage situation, hydraulic shear lift tables 200 with different lifting heights can be used to meet the maintenance requirements at different heights.
