[0035] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0037] Please refer to Figures 1 to 8 The utility model provides an engine ground support device, which includes a body 1, a moving mechanism 2 and a lifting mechanism 3 are provided at opposite ends of the bottom surface of the body 1, a clamping block 11 is provided on the body 1, and the lifting mechanism 3 includes a rotating wheel 31 and a rotating rod 32 that rotates with the rotating wheel 31. One end of the rotating rod 32 is connected to the clamping block 11, and the other end of the rotating rod 32 drives the rotating wheel 31 to separate from or abut against the ground when the rotating rod 32 is lifted or pressed down, so that one end of the body 1 contacts the ground and is in a storage state, or the body 1 is in a movable state driven by the moving mechanism 2 and the rotating wheel 31.

[0038] The main body 1 has a storage state and a movable state. When the main body 1 is in the storage state, the rotating rod 32 is lifted up. At this time, the rotating wheel 31 moves upward and separates from the ground under the rotation of the rotating rod 32. At the same time, the lower end of the main body 1 close to the lifting mechanism 3 is in direct contact with the ground. Therefore, under the support of the contact end and the moving mechanism 2, the main body 1 is in the storage state. At this time, because one end of the main body 1 is in direct contact with the ground, the friction force is large and it is difficult to move, so the storage stability is higher.

[0039] When the main body 1 is in a movable state, the end of the rotating rod 32 away from the main body 1 is pressed downward, and the downward pressure drives the rotating wheel 31 to move downward and contact the ground. At this time, under the support of the rotating wheel 31 and the moving mechanism 2, the main body 1 can move to meet the movement requirements of the main body 1.

[0040] Therefore, the body 1 can be in a relatively stable storage state under the driving action of the lifting mechanism 3 and can be in a movable state under the cooperation of the rotating wheel 31 and the moving mechanism 2 .

[0041] In one embodiment, one end of the rotating rod 32 is detachably connected to the clamping block 11 .

[0042] That is, when the body 1 needs to be stored, the rotating rod 32 can be lifted up and removed, so that one end of the body 1 is in contact with the ground to be in a static storage state. When the body 1 needs to be moved, the rotating rod 32 can be installed and pressed down to lift the body 1, and the body 1 is driven to move under the action of the rotating wheel 31 and the moving mechanism 2.

[0043] The above-mentioned manner is a detachable manner of the rotating rod 32 , and the rotating rod 32 may also be installed on the main body 1 all the time until it needs to be repaired or replaced and then disassembled, which is not limited here.

[0044] In order to prevent the device from tilting too much and becoming unstable when stored, a support protrusion 12 is provided at the bottom end of the main body 1 near the lifting mechanism 3 , and the height of the support protrusion 12 is smaller than the height of the moving mechanism 2 .

[0045] When the rotating rod 32 is in the lifted state, the rotating wheel 31 is separated from the ground and the bottom end of the supporting protrusion 12 contacts the ground to make the main body 1 stationary; when the rotating rod 32 is in the pressed down state, the bottom end of the supporting protrusion 12 is separated from the ground, and the rotating wheel 31 moves downward under the rotation of the rotating rod 32 and contacts the ground to make the main body 1 in a movable state.

[0046] The provision of the supporting protrusion 12 can reduce the inclination angle of the main body 1 when it is stored, so that the storage stability of the main body 1 is stronger.

[0047] The support protrusion 12 can be integrally provided with the main body 1 , or can be connected to the main body 1 by welding or bolt connection, which is not limited here.

[0048] Please continue to refer to Figure 2 and Figure 3 The rotating wheel 31 and the clamping block 11 are arranged on one side of the supporting protrusion 12 and are arranged near the bottom end of the main body 1. In this way, when the rotating rod 32 is lifted up and pressed down, the rotating wheel 31 only needs to move a short distance to be separated from or abut against the ground, thereby effectively preventing the main body 1 from having excessive impact with the ground when switching from the moving state to the storage state, thereby damaging the structure of the main body 1.

[0049] In one embodiment, one end of the clamping block 11 is detachably connected to the body 1 via a threaded connector, a clamping space 111 is defined at the bottom of the clamping block 11 , and one end of the rotating rod 32 extends into the clamping space 111 and rotates with the clamping block 11 .

[0050] The engaging space 111 faces the ground and is arc-shaped. When the rotating rod 32 cooperates with the engaging block 11 , when the rotating rod 32 is lifted or pressed down, the rotating wheel 31 will also move up and down, and then be separated from or abutted against the ground.

[0051] Specifically, the clamping block 11 is provided with a stop block 112 at one end of the clamping space 111 , and when the rotating rod 32 is pressed down, one end of the rotating rod 32 abuts against the stop block 112 .

[0052] When the main body 1 is in a moving state, in order to prevent the rotating rod 32 from shaking, a stop block 112 is further provided on the clamping block 11. Thus, under the action of downward pressure, one end of the rotating rod 32 forms an effective abutment with the stop block 112 to prevent the rotating rod 32 from further rotating. The user only needs to maintain continuous downward pressure to ensure that the main body 1 can continue to move.

[0053] Please continue to refer to Figure 4 and Figure 5 The rotating wheel 31 includes two wheel bodies 311 and a connecting column 312 connected to the two wheel bodies 311. The two wheel bodies 311 are installed on opposite sides of the connecting column 312; one end of the rotating rod 32 is sleeved on the connecting column 312 and rotates with the connecting column 312.

[0054] That is, when the rotating rod 32 is lifted to the target position, one end of the rotating rod 32 abuts against the stop block 112, and the two wheels 311 abut against the ground. When the user maintains continuous downward pressure on the other end of the rotating rod 32 and pushes the main body 1 toward the target position, the rotating wheel 31 and the moving mechanism 2 can drive the main body 1 to move.

[0055] Specifically, a mating block 321 is provided at the mating end of the rotating rod 32 and the clamping block 11. The mating block 321 has an abutting surface 322 on one end surface facing the clamping space 111. When the rotating rod 32 is pressed down, the abutting surface 322 abuts against the inner wall surface of the clamping space 111.

[0056] That is, one end of the rotating rod 32 can be completely connected to the body 1 by the cooperation between the matching block 321 and the clamping block 11. For example, when the body 1 needs to be moved, the matching block 321 of the rotating rod 32 is inserted into the clamping space 111, and one end of the matching block 321 is abutted against the stop block 112, and the friction between the abutting surface 322 and the inner wall surface of the clamping space 111 is further relied on to ensure that the rotating rod 32 will not be separated from the clamping block 11.

[0057] Alternatively, the clamping block 11 may also be provided with a clamping groove 113 in the clamping space 111, and one end of the rotating rod 32 is slidably connected to the clamping groove 113 (see Figure 3 ).

[0058] The engaging groove 113 can guide and limit the rotating rod 32 , and can also prevent the rotating rod 32 from being separated from the main body 1 when the main body 1 is in a moving state.

[0059] The shape of the clamping groove 113 can be T-shaped, and a T-shaped block is also provided at one end of the rotating rod 32 to cooperate with it. The specific installation and cooperation method between the rotating rod 32 and the clamping block 11 is not limited here.

[0060] In one embodiment, the engaging space 111 is arc-shaped, and one end of the matching block 321 that matches with the inner wall of the engaging space 111 is also arc-shaped, so that when the rotating rod 32 is lifted or pressed down, the rotating wheel 31 moves upward or downward to disengage from or abut against the ground.

[0061] Please refer to Figures 6 to 8 As for the moving mechanism 2 , the moving mechanism 2 includes at least two universal wheels 21 , and the two universal wheels 21 are arranged at intervals along the width direction of the body 1 .

[0062] The main body 1 can move freely in multiple directions under the action of the universal wheels 21 and the rotating wheels 31, so that the main body 1 can be quickly moved to the target position.

[0063] Specifically, the universal wheel 21 includes a bayonet, two wheels, a lower connecting plate, an upper connecting plate, bolts and nuts. In order to improve the vibration reduction effect of the main body 1, a shock-absorbing block 22 is further provided between the universal wheel 21 and the main body 1.

[0064] The two wheels are connected to the bayonet through bearings, and the upper connecting plate is used to connect to the main body 1. There is a rotating shaft between the upper connecting plate and the lower connecting plate. The lower connecting plate rotates with the rotating shaft to meet the multi-directional movement requirements of the wheels. The lower connecting plate is connected to the bracket installed on the wheel.

[0065] The shock absorbing block 22 is installed between the upper connecting plate and the lower connecting plate and extends to the upper connecting plate and the lower connecting plate respectively. The shock absorbing block 22 is a resin shock absorbing block, which can effectively play the role of vibration reduction and buffering. The material of the shock absorbing block is preferably a thermoplastic elastomer, which has the advantages of wear resistance and not easy to fall off.

[0066] In some other optional embodiments, the rotating wheel 31 may be a universal wheel 21, and the moving mechanism 2 may be a unidirectional wheel, which can also meet the multi-directional movement requirements of the main body 1.

[0067] In summary, in the engine ground support equipment of the utility model, a moving mechanism 2 and a lifting mechanism 3 are provided on the main body 1. When the main body 1 needs to be stored, the rotating rod 32 is lifted up to make the rotating wheel 31 leave the ground. At this time, one end of the main body 1 abuts against the ground, so that the main body 1 remains still, thereby improving the stability of the main body 1 when stored; and when the main body 1 needs to be moved, the rotating rod 32 can be pressed down to make the rotating wheel 31 abut against the ground, and the rotating wheel 31 and the moving mechanism 2 cooperate with each other to facilitate the dragging and movement of the main body 1.
