DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a mechanical equipment lifting device, including a lifting plate 2, both sides of the two end surfaces of the lifting plate 2 are rotatably connected with lifting leg assemblies 1, each lifting leg assembly 1 includes a leg 101, a mounting groove 102 is opened on one side surface of the leg 101, a connecting slider 103 is slidably installed in the mounting groove 102, the connecting slider 103 is rotatably connected to the corresponding side surface of the lifting plate 2 through a rotating shaft, and the connecting slider 103 is connected to the driving device.

[0022] See also Figure 3 The driving device is a hydraulic cylinder 104, which is fixedly mounted on the top surface of the support leg 101. One end of its piston rod extends through a through hole into the mounting slot 102 and is fixedly connected to the top surface of the connecting slider 103.

[0023] In actual use, the hydraulic cylinder 104 can be replaced by a pneumatic cylinder, an electric push rod or other telescopic driving device that can drive the connecting slider 103 to slide in the installation slide groove 102 according to the needs of use, so that the connecting slider 103 can be driven by the driving device to slide and adjust the height of the lifting plate 2 after the overall unfolding.

[0024] Furthermore, a contact plate 105 is fixedly mounted on the bottom end of the support leg 101 , and a non-slip rubber pad is provided on the bottom surface of the contact plate 105 .

[0025] Providing a contact plate 105 at the bottom end of the support leg 101 can increase the contact area to obtain better stability. Meanwhile, providing an anti-skid rubber pad at the bottom of the contact plate 105 can reduce slipping when the overall lifting mechanical equipment is used, thereby obtaining relatively better safety.

[0026] Furthermore, a supporting mechanism is provided under the connecting slider 103, and the supporting mechanism includes a plurality of supporting brackets 106 distributed in parallel, and a guide slider 107 is provided on the top surface of each supporting bracket 106, and each guide slider 107 is slidably connected in a corresponding guide groove 108, and all guide grooves 108 are distributed in parallel and opened on the bottom surface of the connecting slider 103, and all supporting brackets 106 are connected to the driving mechanism.

[0027] All supporting brackets 106 can be driven by the driving mechanism to slide independently relative to the connecting slider 103, so that in the overall unfolded state, the supporting brackets 106 extend to the bottom of the connection between the connecting slider 103 and the lifting plate 2 to support the lifting plate 2, thereby reducing the force at the connection between the connecting slider 103 and the lifting plate 2 and improving the overall support strength and stability.

[0028] Furthermore, the driving mechanism includes a connecting plate 109, which is fixedly connected to all the supporting brackets 106. A threaded hole is provided on one side surface of the connecting plate 109, in which a threaded rod 110 is threadedly connected. One end of the threaded rod 110 is fixedly connected to one end of the output shaft of the motor 111. The motor 111 is fixedly mounted on one end surface of the mounting plate 112, and the other end of the mounting plate 112 is fixedly connected to one side surface of the connecting slider 103.

[0029] The starting motor 111 drives the threaded rod 110 to rotate. Since the connecting plate 109 connects all the supporting brackets 106, and the supporting brackets 106 are slidably connected to the connecting slider 103 through the guide slider 107, the connecting plate 109 is restricted by the guide slider 107 and can only be displaced guided by the guide slider 107 when the threaded rod 110 rotates, thereby driving all the supporting brackets 106 to slide synchronously, realizing the extension and retraction of the supporting brackets 106, which is convenient for the overall adjustment in the two states of expansion and storage.

[0030] Furthermore, each supporting bracket 106 is a triangular structure, and a plurality of reinforcing ribs are arranged in the middle.

[0031] The supporting bracket 106 is configured as a triangular structure and reinforcing ribs are arranged inside it to improve the overall strength, reduce the possibility of deformation under heavy pressure, and improve stability during use. At the same time, the supporting bracket 106 and the guide slider 107 are arranged as one piece, which can also improve the overall strength of the connection between it and the connecting slider 103.

[0032] Furthermore, two side plates 113 are arranged in parallel on one side surface of the bottom end of the supporting leg 101 , and a roller 114 is rotatably installed between the two side plates 113 .

[0033] By arranging a roller 114 at the bottom end of each leg 101, it is possible to facilitate the movement of the entire body in the overall storage state, thereby improving convenience during use.

[0034] Working principle: In the storage state, all the supporting brackets 106 are retracted at the bottom of the corresponding connecting slider 103, and the four legs 101 are placed on the lifting plate 2 through the rotation connection between the connecting slider 103 and the lifting plate 2. The roller 114 touches the ground to support the whole body for easy movement of the whole body. When needed, all the supporting legs 101 are flipped over to make the contact floor 105 replace 114 to touch the ground to support the whole body. At the same time, the motor 111 is started to drive the connecting plate 109 to move outward, and all the supporting brackets 106 are slid out from under the connecting slider 103 to support the lifting plate 2 from the bottom of the lifting plate 2. The mechanical equipment is placed on the lifting plate 2, and all the hydraulic cylinders 104 are started to synchronously drive all the connecting sliders 103 to realize the lifting of the lifting plate 2 and the mechanical equipment as a whole. The device as a whole can be folded to reduce the limitations caused by the large overall structure that is inconvenient to carry, move and store.

[0035] It should be noted that the specific models and specifications of the hydraulic cylinder 104 and the motor 111 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0036] The power supply and principle of the hydraulic cylinder 104 and the motor 111 are clear to those skilled in the art and will not be described in detail here.

[0037] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
