DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 The hydraulic walking mechanism includes a support platform 13. A hand-lever hydraulic lifter 14 is placed on the top of the support platform 13. The hand-lever hydraulic lifter 14 is a relatively mature device today. The telescopic end of the hydraulic cylinder can be moved upward by pressing the hand lever back and forth. Its working principle will not be described in detail here. A connecting shaft 16 is fixedly provided at the bottom of the hand-lever hydraulic lifter 14. A group of walking wheels 17 are rotated and rotated on both sides of the front and rear of the connecting shaft 16 through a rotating shaft. A group of spring pins 15 are fixedly provided on both sides of the front and rear of the hand-lever hydraulic lifter 14. Two groups of locking holes are evenly opened on the top of the support platform 13. The locking rods of the spring pins 15 are inserted into the locking holes. The hand-lever hydraulic lifter 14 can be rotated through the connecting shaft 16. When the hand-lever hydraulic lifter 14 rotates, the two groups of walking wheels 17 are driven to turn through the connecting shaft 16. The locking rods of the spring pins 15 are inserted into the support platform 13. After the locking hole of the platform 13 is inserted into the locking hole of the platform 13, the hand-lever hydraulic lifter 14 can be locked on the support platform 13, so that the walking wheel 17 can only move in a straight line, which can facilitate towing and also ensure that personnel will not accidentally injure personnel due to sudden loss of direction when towing and transferring the cabin. A support plate 1 is placed on the right side of the support platform 13, and a mounting hole is opened on the bottom left side of the support plate 1. The top of the telescopic end of the hand-lever hydraulic lifter 14 is rotated and plugged into the mounting hole. A rotary lock assembly is placed on the outside of the support plate 1. A through hole is opened on the top of the support platform 13, and the connecting shaft 16 is rotatably arranged in the through hole through a bearing. The walking wheel 17 is located below the support platform 13, and a group of connecting arms 12 are rotatably arranged on the front and rear sides of the support plate 1 through a rotating shaft. The support platform 13 is rotatably arranged between the two groups of connecting arms 12 through a rotating shaft, and an anti-slip pad 11 is fixedly arranged on the right side of the support plate 1.

[0023] The rotary lock assembly includes a mounting tube 2 and a rotary lock 21. An annular groove is provided on the top of the mounting tube 2. A first plug hole is provided on the top of the mounting tube 2. A second plug hole is provided on the front side of the mounting tube 2. Both the first plug hole and the second plug hole are connected to the annular groove. The annular groove is connected to the inside of the mounting tube 2. The rotary lock 21 is rotatably arranged inside the mounting tube 2. A connecting rod 211 is fixedly arranged on the front side of the rotary lock 21. The connecting rod 211 is slidably arranged in the annular groove. The outer ring of the connecting rod 211 is sleeved with a sliding sleeve 23. A spring 24 is placed on the outer ring of the connecting rod 211. The two ends of the spring 24 are respectively fixedly connected to the outer side wall of the connecting rod 211 and the inner side wall of the sliding sleeve 23. One end of the sliding sleeve 23 close to the mounting tube 2 is inserted into the second plug hole and corresponds to the first plug hole. A handle 22 is fixedly arranged on the outer ring of the sliding sleeve 23. After the lock head of the lock 21 is inserted into the hole corresponding to the corner piece of the cabin, the anti-slip pad 11 fits against the surface of the cabin. At this time, the outer pull handle 22 drives the sliding sleeve 23 to move forward and separate from the second insertion hole. At this time, the connecting rod 211 can be flipped upward. When the connecting rod 211 is flipped and rotated, it will drive the rotary lock 21 to rotate and lock in the hole of the corner piece of the cabin. At the same time, when the sliding sleeve 23 is flipped upward with the connecting rod 211 and aligned with the first insertion hole, the handle 22 is released, and the sliding sleeve 23 is driven by the rebound force of the spring 24 to insert into the first insertion hole, thereby completing the locking of the connecting rod 211 and then completing the angle fixation of the rotary lock 21. A fixing hole is opened through the right side of the support plate 1, and the mounting tube 2 is arranged in the fixing hole. The lock head part of the rotary lock 21 is located on the right side of the support plate 1, and the part of the mounting tube 2 with the annular groove is located on the left side of the support plate 1.

[0024] Working principle: After the lock head of the rotary lock 21 is inserted into the hole corresponding to the corner piece of the cabin, the anti-slip pad 11 is fitted with the surface of the cabin. At this time, the outer pull handle 22 drives the sliding sleeve 23 to move forward and separate from the second socket. At this time, the connecting rod 211 can be flipped upward. When the connecting rod 211 is flipped and rotated, it will drive the rotary lock 21 to rotate and lock in the hole of the corner piece of the cabin. At the same time, when the sliding sleeve 23 is flipped upward with the connecting rod 211 and aligned with the first socket, the handle 22 is released, and the sliding sleeve 23 is driven to be inserted into the first socket by the rebound force of the spring 24, thereby completing the locking of the connecting rod 211, and then completing the angle fixation of the rotary lock 21, and then the hand lever is pressed back and forth. The hand lever on the hydraulic lifter 14 can make the telescopic end of the hand lever hydraulic lifter 14 move upward and then move against the support plate 1. The support plate 1 lifts the cabin by rotating the lock 21. The hand lever hydraulic lifter 14 can be rotated through the connecting shaft 16. When the hand lever hydraulic lifter 14 rotates, the two sets of running wheels 17 are driven to turn through the connecting shaft 16. After the locking rod of the spring pin 15 is inserted into the locking hole of the support platform 13, the hand lever hydraulic lifter 14 can be locked on the support platform 13, so that the running wheels 17 can only move in a straight line, which can facilitate towing and also ensure that personnel will not be accidentally injured due to losing direction due to sudden rotation when towing and transferring the cabin.
