Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a modular cabin lifting and walking device. Background Technology

[0002] Prefabricated modular shelters, serving as environments for carrying equipment and personnel, possess excellent mobility and environmental adaptability, and are widely used in various emergency support and field operations. To facilitate the relocation of modular shelters, lifting and moving devices are typically installed around their perimeter, enabling autonomous lifting and movement.

[0003] The existing lifting and traveling device includes four lifting mechanisms and casters. The four lifting mechanisms are connected to the four corners of the container. The lifting mechanism adjusts the height of the container off the ground, which facilitates the loading or unloading of the container. The container can be moved by towing the lifting and traveling device.

[0004] While existing lifting and moving devices facilitate the loading, unloading, and transfer of modular shelters, several problems exist during use. First, although the casters facilitate shelter movement, the two casters at the leading traction end are difficult to control when turning or on rough terrain. This leads to significant friction between the casters and the ground, damaging them and reducing their lifespan. This is especially true when the shelter itself is heavy, as uncontrolled steering angles cause substantial wear on the casters. Second, the lifting mechanisms of existing devices operate independently, resulting in poor overall stability. Utility Model Content

[0005] To address the aforementioned deficiencies, the technical problem to be solved by this utility model is to provide a container lifting and walking device that can synchronize the steering of two wheels, improve the stability of wheel steering, and reduce wheel wear.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A mobile shelter lifting and walking device includes:

[0008] Two traveling mechanisms, each traveling mechanism including a mounting base, a steering base, a lifting assembly, and wheels, wherein the steering base is rotatably mounted on the mounting base, the wheels are rotatably mounted on the steering base, and the lifting assembly is disposed on the mounting base;

[0009] The traction mechanism includes a traction crossbar, a swing arm, and two tie rods. The two ends of the traction crossbar are connected to two mounting seats in a one-to-one correspondence. The first end of the swing arm is hinged to the traction crossbar. The first ends of both tie rods are hinged to the second ends of the swing arm, and the second ends of both tie rods are hinged to two steering seats in a one-to-one correspondence. When the swing arm swings, it can drive the steering seats to rotate via the tie rods, thereby steering the wheels.

[0010] By adopting the above scheme, during use, the lifting assembly is connected to the container via the free end of the traction swing arm, i.e., the end of the swing arm away from the traction crossbar. The lifting assembly can drive the container to rise and fall. When the traction direction changes, the traction power causes the swing arm to swing relative to the traction crossbar. The swing arm synchronously drives the two steering seats to rotate through two tie rods. The rotation of the steering seats causes the corresponding wheels to turn, thus enabling the two wheels to turn synchronously. This prevents the wheels from deflecting in any direction, thereby reducing wheel wear, increasing wheel lifespan, and thus increasing the lifespan of the lifting and traveling device. It can adapt to short-distance manual traction as well as rapid vehicle traction.

[0011] Preferably, the traveling mechanism further includes a pin, the mounting base has a protrusion with a hole, and the steering seat has a slot. The pin passes through the hole and the slot. When only straight-line towing of the container is required, the pin is inserted into the hole and the slot to restrict the steering of the steering seat, thereby limiting the steering of the wheels and enabling the container to travel in a straight line in a single direction.

[0012] Preferably, the steering seat is provided with a first fixing member, one end of which extends above the wheel, and the second end of the tie rod is hinged to the corresponding end of the first fixing member away from the steering seat. Because the first fixing member extends above the wheel, the tie rod is less likely to interfere with the wheel when pulling the wheel to steer, resulting in a more reasonable structural layout.

[0013] Preferably, the second end of the swing arm is hinged to a first traction rod, which can swing in a vertical plane around the hinge point with the swing arm. In use, the entire container is towed forward by the first traction rod, and the traction power is connected to the end of the first traction rod away from the swing arm. Since the first traction rod can swing in a vertical plane around the hinge point with the swing arm, it can be easily connected to the connection points of traction power at different heights.

[0014] Preferably, the steering seat is equipped with a second fixing member, which is detachably connected to a second traction rod, and the second traction rod is equipped with a handle. The second traction rod and handle allow for convenient manual pulling of the modular container over short distances.

[0015] Preferably, the lifting assembly includes a lifting frame, a lifting cylinder, and two connecting rods. The two connecting rods are arranged in parallel, with each end of the connecting rod hinged to a corresponding mounting frame and a mounting base. One end of the lifting cylinder is hinged to the mounting base, and the other end of the lifting cylinder is hinged to the top of the lifting frame. In use, the lifting frame connects to the shelter, and the lifting cylinder drives the lifting frame to rise. The lifting frame is constrained by the two parallel connecting rods, allowing it to move vertically and thus lift the shelter vertically. The parallel double connecting rods improve the stability of the shelter's lifting and lowering and reduce structural complexity.

[0016] Preferably, the lifting cylinder is a hydraulic cylinder. Using a hydraulic cylinder allows for the lifting of heavier containers.

[0017] Preferably, the lifting cylinder is a double-acting hydraulic cylinder. The use of a double-acting hydraulic cylinder prevents the container from descending too quickly, resulting in a smoother descent and thus avoiding damage to the overall lifting structure.

[0018] Preferably, the lifting assembly also includes a hand-cranked pump for driving the piston movement of the lifting cylinder. The hand-cranked pump facilitates the operation of the lifting cylinder.

[0019] Preferably, the system also includes a stabilizer bar, with each end of the stabilizer bar connected to one of the two lifting frames. The connection point between the stabilizer bar and the lifting frame is located at the upper section of the lifting frame. The stabilizer bar can restrain the upper ends of the two lifting frames, thereby improving overall stability. Attached image description:

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-8 The present invention will be further described in detail below with reference to specific embodiments.

[0030] Please see Figure 1-8 This embodiment provides a modular shelter lifting and walking device, including a walking mechanism 1 and a traction mechanism 2, with two walking mechanisms 1. The walking mechanism 1 includes a mounting base 101, a steering base 102, a lifting assembly 103, and wheels 104. The steering base 102 is rotatably mounted on the mounting base 101 and can rotate horizontally relative to the mounting base 101. The wheels 104 are rotatably mounted on the steering base 102, and the lifting assembly 103 is disposed on the mounting base 101. The traction mechanism 2 includes a traction crossbar 201, a swing arm 202, and two tie rods 203. The two ends of the traction crossbar 201 are connected to two mounting seats 101 one-to-one. The first end of the swing arm 202 is hinged to the traction crossbar 201. The first ends of both tie rods 203 are hinged to the second ends of the swing arm 202, and the second ends of both tie rods 203 are hinged to two steering seats 102 one-to-one. When the swing arm 202 swings (i.e., swings around the hinge point with the traction crossbar 201), the swing arm 202 can drive the steering seats 102 to rotate via the tie rods 203, thereby turning the wheels 104. In this embodiment, preferably, the wheels 104 are connected to the steering seats 102 via an axle 111. The axle 111 passes laterally through the steering seats 102 and is rotatably connected to the steering seats 102. Wheels 104 are fixedly connected to both ends of the axle 111.

[0031] By adopting the above scheme, during use, the free end of the traction swing arm 202, that is, the end of the swing arm 202 away from the traction crossbar 201, is used. The lifting assembly 103 is connected to the container 4, and the lifting assembly 103 can drive the container 4 to rise and fall. When the traction direction changes, the traction power causes the swing arm 202 to swing relative to the traction crossbar 201. The swing arm 202 synchronously drives the two steering seats 102 to rotate through the two tie rods 203. The rotation of the steering seats 102 drives the corresponding wheels 104 to turn, so that the two wheels 104 can turn synchronously. This can prevent the wheels 104 from deflecting in any direction, thereby reducing the wear of the wheels 104, increasing the service life of the wheels 104, and thus increasing the service life of the lifting and traveling device. It can adapt to both short-distance manual traction and rapid vehicle traction.

[0032] To facilitate the straight-line movement of the modular container 4, the traveling mechanism 1 also includes a pin 105. The mounting base 101 has a protrusion 106 with a hole, and the steering seat 102 has a slot. The pin 105 passes through the hole and slot. When only straight-line movement of the modular container 4 is required, the pin 105 is inserted into the hole and slot to restrict the steering of the steering seat 102, thereby limiting the steering of the wheels 104 and enabling the modular container 4 to travel in a single direction in a straight line.

[0033] The steering seat 102 is provided with a first fixing member 107, which is rod-shaped. The lower end of the first fixing member 107 is fixed to the upper side of the steering seat 102. The connection point between the first fixing member 107 and the steering seat 102 is located at the eccentric position of the rotation axis between the steering seat 102 and the mounting seat 101. The upper end of the first fixing member 107 extends to the top of the wheel 104. The second end of the tie rod 203 is hinged to the end of the corresponding first fixing member 107 away from the steering seat 102.

[0034] The second end of the swing arm 202 is hinged to a first traction rod 204, which can swing in a vertical plane around the hinge point with the swing arm 202. To facilitate the connection of the first traction rod 204 to the traction power source, in this embodiment, a traction ring 206 is preferably fixedly connected to the end of the first traction rod 204 away from the swing arm 202. The traction ring 206 allows for easy attachment to a tractor or other traction equipment.

[0035] The steering seat 102 is provided with a second fixing member 108, and the second fixing member 108 is detachably connected to a second traction rod 109, and the second traction rod 109 is provided with a handle 110.

[0036] The lifting assembly 103 includes a lifting frame 1031, a lifting cylinder 1032, and two connecting rods 1033. The two connecting rods 1033 are arranged in parallel, with their ends hinged to the lifting frame 1031 and the mounting base 101 respectively. The lower end of the lifting cylinder 1032 is hinged to the mounting base 101, and the upper end of the lifting cylinder 1032 is hinged to the top of the lifting frame 1031. Specifically, the lifting cylinder 1032 is a hydraulic cylinder, preferably a double-acting hydraulic cylinder. The cylinder body of the lifting cylinder 1032 is hinged to the mounting base 101, and the piston rod of the lifting cylinder 1032 is hinged to the top of the lifting frame 1031.

[0037] To facilitate the driving of the lifting cylinder 1032, the lifting assembly 103 also includes a hand-cranked pump 1034, which is used to drive the piston movement of the lifting cylinder 1032. The hand-cranked pump 1034 is prior art; it is an oil pump powered by hand-cranking, which facilitates the operation of the lifting cylinder 1032.

[0038] To improve the stability of the overall structure, a stabilizer bar 205 is also included. The two ends of the stabilizer bar 205 are connected to the two lifting frames 1031 one by one. The connection position between the stabilizer bar 205 and the lifting frame 1031 is located in the upper section of the lifting frame 1031.

[0039] To facilitate the connection between the lifting frame 1031 and the container 4, a rotary lock 3 can be installed at the lower part of the lifting frame 1031 to connect to the corner of the container 4. The rotary lock 3 includes a rotating handle, a connecting pin, and a connecting block connected in sequence. The connecting pin passes through the lifting frame 1031 and is rotatably connected to the lifting frame 1031. The connecting block is a rectangular or elliptical block. The corner of the container 4 has a groove that fits the shape of the rectangular block, and the inner wall of the groove has a slot. In use, after the connecting block passes through the groove, the rotating handle drives the connecting pin to rotate, and the connecting pin drives the connecting block to rotate. The connecting block is then engaged in the slot. Through the cooperation of the connecting block and the slot, the connecting pin is connected to the container 4, thereby connecting the lifting frame 1031 and the container 4 together.

[0040] In use, the above-described solution involves a rectangular container 4 with two walking mechanisms 1 corresponding to the two corners of the bottom of the container 4. The two walking mechanisms 1 are located at one end of the container 4 in the forward direction, i.e., the traction end. The two rear corners of the bottom of the container 4 can be equipped with existing lifting and walking devices, or the walking mechanisms 1 of this application can be used. By using the walking mechanisms 1 of this application at the rear of the bottom of the container 4, the traction mechanism 2 is unnecessary; only the structure of the walking mechanisms 1 is required.

[0041] To better accommodate container 4 of different widths, in some embodiments, the traction crossbar 201, the stabilizing bar 205, and the tie rod 203 all adopt telescopic rod-like structures.
