[0027] By cooperating among the support assembly 2, the first hydraulic rod 6, the support foot 9, the first support rod 11, the second support rod 12, etc., the support foot 9 can be directly installed in the fixed cavity on the side of the cabin during operation, and the overall height adjustment of the cabin can be achieved through the overall extension of the first hydraulic rod 6 and the second hydraulic rod 10. Furthermore, during loading, by lifting the cabin as a whole, it is convenient to move the crane to the bottom of the cabin for loading, which can avoid the use of the crane to tie the ropes and lift the cabin, thereby improving the overall loading efficiency.
[0028] A scale plate 32 is embedded and installed on the outer side of the first support column 3. The scale plate 32 is engraved with scale lines. The scale plate 32 can be used to effectively determine the overall extension height of the second support column 4 during operation.
[0029] A fixing ring 61 is fixed at the bottom of one side of the second support column 4 corresponding to the first hydraulic rod 6, and the fixing ring 61 is clamped and installed on the first hydraulic rod 6. By setting the fixing ring 61, it can be ensured that the first hydraulic rod 6 can be stably and vertically installed on the outer side of the second support column 4 during operation, and the first hydraulic rod 6 can be prevented from bending in the middle section during the extension process.
[0030] Reference Figure 1 , Figure 3 and Figure 4 As shown, a positioning hook 8 is fixed to the support component 2 corresponding to the protruding frame 7, and the end of the positioning hook 8 away from the protruding frame 7 is in the shape of an arc-shaped hook. The first support rod 11 is hollow inside to form a positioning cavity, and the positioning cavity is installed with a positioning component 13 that cooperates with the first support rod 11 for positioning. The positioning component 13 includes a fixed hook 131 fixed inside the positioning cavity and a sliding block 14 slidably arranged inside the protruding frame 7. An oblong clamping groove 111 is opened at the middle section of the first support rod 11, and a positioning pin 16 is slidably arranged in the clamping groove 111. A fixed chain 15 is installed between the sliding block 14 and the positioning pin 16 and around the pin shaft, and a reset spring 17 for auxiliary tensioning is installed between the fixed hook 131 and the positioning pin 16.
[0031] Through the cooperation between the provided positioning hook 8 and the first support rod 11, etc., the second hydraulic rod 10 is started, and the second hydraulic rod 10 is extended to drive the second support rod 12 to be pushed, so that the support leg 9 is unfolded as a whole. After the support leg 9 is unfolded, when the positioning pin 16 on the first support rod 11 reaches the positioning hook 8 when the support leg 9 is unfolded, the positioning pin 16 rises as a whole along the arc hook shape, and in the process of the positioning pin 16 rising along the arc hook shape, the reset spring 17 is stretched as a whole. When the positioning pin 16 reaches the inner side of the hook, it enters the hook as a whole under the action of the stretched reset spring 17, so that the first support rod 11 is auxiliaryly hung and tightened by the positioning hook 8, thereby performing auxiliary support processing on the support leg 9, which can avoid the second hydraulic rod 10 from being damaged due to large force during the lifting process as much as possible.
[0032] A slideway is provided between the second support column 4 and the protruding frame 7, and the sliding block 14 is slidably arranged in the slideway. A rotating wheel is rotatably arranged at one end of the sliding block 14 corresponding to the protruding frame 7. By setting the rotating wheel 14, the overall friction of the sliding block 14 can be reduced during the movement of the sliding block 14.
[0033] Working principle:
[0034] During operation, the support leg 9 is installed on the side of the cabin. When the support leg 9 needs to support the cabin, the first hydraulic rod 6 is pre-extended for a certain height, and the second hydraulic rod 10 is started. The extension of the second hydraulic rod 10 drives the second support rod 12 to be pushed, so that the support leg 9 is unfolded as a whole. After the support leg 9 is unfolded, when the positioning pin 16 on the first support rod 11 reaches the positioning hook 8 when the support leg 9 is unfolded, the positioning pin 16 rises as a whole along the arc hook shape, and in the process of the positioning pin 16 rising along the arc hook shape, the reset spring 17 is stretched as a whole. When the positioning pin 16 reaches the inner side of the hook, it enters the hook as a whole under the action of the stretched reset spring 17, so that the first support rod 11 is auxiliary hung and tightened through the positioning hook 8, thereby performing auxiliary support processing on the support leg 9. When the cabin needs to be lifted, the first hydraulic rod 6 is extended as a whole. During the extension of the first hydraulic rod 6, the second support column 4 is driven to rise as a whole, so that the overall height of the support leg 9 is adjusted. After the work is completed, the first hydraulic rod 6 is shortened as a whole and drives the support assembly 2 to shorten as a whole. When the top block 31 lifts the sliding block 14, the fixed chain 15 is pulled as a whole, so that the positioning pin 16 is pulled as a whole. In the process of the positioning pin 16 being pulled, the return spring 17 is pulled and extended, so that the positioning pin 16 is disengaged from the arc hook on the positioning hook 8. At this time, the second hydraulic rod 10 is shortened as a whole, so that the support leg 9 is restored to its original state, and one end of the first hydraulic rod 6 is extended. Under the action of the extended return spring 17, the positioning pin 16 is pulled to restore its original position.
[0035] All technical features in this embodiment can be freely combined according to actual needs.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
