Description

Technical Field

[0001] This utility model relates to the field of lifting technology, specifically to a hydraulic lifting trestle. Background Technology

[0002] During construction, workers need to perform tasks such as bricklaying, plastering, and installing doors and windows at different heights. Elevators provide workers with a stable and safe high-altitude working platform, reducing the tedious work of erecting scaffolding and improving construction efficiency and safety. Existing scissor lifts, with their high stability and large load-bearing capacity, achieve platform lifting through the extension and retraction of the scissor lifting components and are widely used in various types of elevators. However, traditional elevators require manual removal or retraction of limit devices during operation, reducing work efficiency and providing a poor user experience. Therefore, there is an urgent need for a device that can effectively solve these problems to enable elevators to be quickly supported or moved. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a hydraulic lifting trestle, which solves the technical problem that lifting machines in related technologies cannot quickly support or move.

[0004] According to one aspect, at least one embodiment of the present invention provides a hydraulic lifting trestle, comprising:

[0005] Base;

[0006] The scissor lift assembly is mounted on the base.

[0007] A platform is mounted on the scissor lift assembly, and the platform can move up and down with the scissor lift assembly;

[0008] A movable wheel is mounted on the scissor lift assembly, and the movable wheel can move up and down with the scissor lift assembly;

[0009] When the moving wheel rises with the scissor lift assembly, the moving wheel leaves the ground and the base touches the ground. When the moving wheel falls with the scissor lift assembly, the moving wheel touches the ground and the base leaves the ground.

[0010] For example, at least one embodiment of this utility model provides a hydraulic lifting trestle, wherein the scissor lift assembly includes:

[0011] The scissor lift arm has two sets, which are located on both sides of the base. The two ends of the scissor lift arm are respectively hinged to the base and the platform. The scissor lift arm can drive the platform to lift.

[0012] The crossbeam has several parts, and its two ends are respectively connected to two sets of scissor lift arms. The crossbeam can move up and down with the scissor lift arms, and the moving wheels are arranged on the crossbeam.

[0013] The telescopic component has two ends rotatably mounted on the crossbeam, and the telescopic component can drive the scissor lift arm to rise and fall through the crossbeam.

[0014] For example, at least one embodiment of this utility model provides a hydraulic lifting trestle, wherein the moving wheels include:

[0015] A connecting rod, one end of which is mounted on the crossbeam;

[0016] The traveling wheel is rotatably mounted on the other end of the connecting rod.

[0017] For example, at least one embodiment of this utility model provides a hydraulic lifting stool, wherein the bottom of the base has a supporting leg, and when the moving wheel rises, the supporting leg abuts against the ground, and when the moving wheel descends, the supporting leg separates from the ground.

[0018] For example, at least one embodiment of this utility model provides a hydraulic lifting trestle, wherein the base includes:

[0019] frame;

[0020] The support leg is rotatably mounted on the frame. The height of the support leg changes after it rotates. When the support leg rotates to the outside of the frame, it can support the elevator.

[0021] For example, at least one embodiment of this utility model provides a hydraulic lifting trestle, which further includes:

[0022] A handle is detachably mounted on the platform, and the handle extends upward in a direction perpendicular to the platform.

[0023] For example, at least one embodiment of this utility model provides a hydraulic lifting stool, wherein the base has a limiting member, and the handle passes through the platform and is limitedly connected to the limiting member.

[0024] For example, at least one embodiment of this utility model provides a hydraulic lifting trestle, wherein the base also has a limiting rod located above the base, and the platform can abut against the limiting rod after it is lowered.

[0025] For example, at least one embodiment of this utility model provides a hydraulic lifting trestle, wherein both the top crossbeam and the bottom crossbeam are provided with travel plates, and further includes:

[0026] There are two limit switches, both located at the bottom of the platform. When the scissor lift assembly rises, the travel plate on the top crossbeam triggers one limit switch. When the scissor lift assembly descends, the travel plate on the bottom crossbeam triggers the other limit switch.

[0027] For example, at least one embodiment of the present invention provides a hydraulic lifting trestle, which also includes a control box disposed on one side of the platform. The control box is used to control the extension and retraction of the telescopic component.

[0028] The beneficial effects of the embodiments of this utility model are as follows:

[0029] In this invention, the operator controls the scissor lift assembly to rise, and the moving wheels follow the assembly upwards until they are separated from the ground. Simultaneously, the base contacts the ground, supporting the lift. At this point, the scissor lift assembly stops rising, and the lift cannot move. Workers carry materials onto the platform and control the scissor lift assembly to continue rising. Once the target position is reached, the scissor lift assembly stops rising, completing the task. After the task is completed, the operator controls the scissor lift assembly to descend, stopping just before the moving wheels touch the ground. After returning to the ground, the operator continues to control the scissor lift assembly to descend. At this point, the moving wheels contact the ground, and the base separates from the ground, allowing the operator to move the lift. By placing the moving wheels on the scissor lift assembly, the support and movement of the lift are more tightly integrated. The operator only needs to control the raising and lowering of the scissor lift assembly to support or move the lift, reducing the steps required to fix the lift and improving operator efficiency.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0039] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0043] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] like Figures 1-4 As shown, this invention illustrates a hydraulic lifting trestle according to one embodiment. In this embodiment, to solve the technical problem that lifting mechanisms cannot quickly support or move in related technologies, a scissor lift assembly 2 is provided on the hydraulic lifting base 1. A platform 3 is provided on the scissor lift assembly 2, which can move up and down with the scissor lift assembly 2. A moving wheel 4 is provided on the scissor lift assembly 2, which can move up and down with the scissor lift assembly 2. After the moving wheel 4 rises with the scissor lift assembly 2, the moving wheel 4 leaves the ground and the base 1 contacts the ground. After the moving wheel 4 falls with the scissor lift assembly 2, the moving wheel 4 contacts the ground and the base 1 leaves the ground.

[0045] Specifically, the operator controls the scissor lift assembly 2 to rise, and the moving wheels 4 follow the scissor lift assembly 2 upwards and separate from the ground. At the same time, the base 1 touches the ground, and the lift is supported on the ground. The scissor lift assembly 2 stops rising, and the lift cannot move. The worker carries the materials onto the platform 3 and controls the scissor lift assembly 2 to continue rising. After reaching the target position, the operator controls the scissor lift assembly 2 to stop rising, thus completing the work. After the work is completed, the operator controls the scissor lift assembly 2 to descend. The descent stops when the moving wheels 4 are about to touch the ground. The worker returns to the ground from the platform 3 and continues to control the scissor lift assembly 2 to descend. At this point, the moving wheels 4 touch the ground, and the base 1 separates from the ground, allowing the operator to move the lift. Placing the moving wheels 4 on the scissor lift assembly 2 makes the support and movement of the lift more seamless. The operator only needs to control the raising and lowering of the scissor lift assembly 2 to complete the support or displacement of the lift, reducing the steps required to fix the lift and improving the operator's work efficiency.

[0046] like Figures 1-3 As shown, in this embodiment, the scissor lift assembly 2 includes two sets of scissor lift arms 201, which are disposed on both sides of the base 1. The two sides of the scissor lift arms 201 are hinged to the base 1 and the platform 3. The two sets of scissor lift arms 201 are connected by a crossbeam 202. The two sets of scissor lift arms 201 and the crossbeam 202 can be raised and lowered synchronously. The moving wheels 4 are disposed on the crossbeam 202 and can follow the crossbeam 202 in raising and lowering. The two ends of the telescopic member 203 are rotatably disposed on the crossbeam 202. The telescopic member 203 can drive the scissor lift arms 201 to rise and fall through the crossbeam 202.

[0047] Specifically, the telescopic component 203 extends and retracts, applying a pushing or pulling force to the crossbeam 202. The crossbeam 202 displaces under the force, simultaneously driving the scissor lift arms 201 on both sides to move up and down. The telescopic component 203 and the crossbeam 202 are hinged. The moving wheels 4 are fixedly connected to the crossbeam 202, and they swing along with the crossbeam 202 during lifting and lowering. Preferably, the telescopic component 203 is a hydraulic cylinder, but it can also be a pneumatic cylinder or an electric component; no limitation is made here.

[0048] like Figure 3 As shown, in this embodiment, the movable wheel 4 includes a connecting rod 401 and a traveling wheel 402. One end of the connecting rod 401 is connected to the crossbeam 202, and the traveling wheel 402 is disposed at the other end of the connecting rod 401. The traveling wheel 402 is preferably a swivel wheel, but it can also be other steerable wheels or a combination of swivel wheels and directional wheels, which is not limited here.

[0049] like Figure 1As shown, in this embodiment, the base 1 is provided with a support leg 101. After the base moves up, the support leg 101 comes into contact with the ground. After the moving wheel 4 descends, the support leg 101 separates from the ground. The support leg 101 prevents the base 1 from directly contacting the ground and has a protective function for the base 1.

[0050] like Figures 5-6 As shown, in this embodiment, the base 1 includes a frame 102 and a support leg 101. The support leg 101 is rotatably mounted on the frame 102. The support leg 101 can be unfolded and retracted. When the support leg 101 is unfolded, it can support the elevator. At this time, the moving wheel 4 is off the ground or tangent to the ground and cannot move. When the support leg 101 is retracted, the moving wheel 4 is in contact with the ground and can move. The retractable support leg 101 can be used in more complex elevators. When the moving wheel 4 conflicts with the crossbeam 202 or other parts during lifting, the moving wheel 4 can be installed in other parts, and a foldable support leg 101 can be selected. This design improves the compatibility of the moving wheel 4 and the support leg 101 with elevators of different structures and enriches the functions of the elevator.

[0051] like Figures 1-3 As shown, in this embodiment, a detachable handle 5 is provided on the platform 3 to facilitate the movement of the elevator. The handle 5 extends upward in a direction perpendicular to the platform 3. In order to prevent the handle 5 from shaking when moving, the handle 5 passes through the platform 3 and abuts against the base 1. Furthermore, a limiting member 103 is provided on the base 1, and the handle 5 is connected to the limiting member 103. When the elevator is working, the handle 5 can be removed and replaced with a guardrail, which increases the mobility of the elevator and improves its safety.

[0052] like Figures 1-2 As shown, in this embodiment, the base 1 has a limiting rod 104. After the platform 3 descends to the designated position, the platform 3 can abut against the limiting rod 104 to restrict the platform 3 from continuing to descend. The limiting rod 104 can prevent the platform 3 from descending excessively during descent, which would cause damage to the scissor lift arm 201 due to compression.

[0053] like Figure 2 and Figure 4As shown, in this embodiment, to limit the lifting distance of the elevator, two limit switches 7 are provided at the bottom of the platform 3. A travel plate 6 is also provided on the crossbeam 202. When the crossbeam 202 moves up and down, the travel plate 6 can contact or separate from the limit switches 7. After the scissor lift assembly 2 rises, the travel plate 6 on the top crossbeam 202 triggers one limit switch 7. After the scissor lift assembly 2 descends, the travel plate 6 on the bottom crossbeam 202 triggers the other limit switch 7. The limit switches 7 can limit the lifting of the scissor lift assembly 2. The limit switches 7 prevent the scissor lift assembly 2 from rising or falling excessively, protecting it from damage. Both the limit switches and travel plates are existing technologies and will not be described in detail here.

[0054] like Figure 1 As shown in this embodiment, in order to facilitate operation, a control box 8 is provided on one side of the platform 3. The control box 8 can control the extension and retraction of the telescopic component 203, and further control the lifting and lowering of the scissor lift assembly 2. The preferred operation mode of the control box 8 is button operation, but it can also be a foot pedal that can realize the control function. There is no limitation here. The operator can raise and lower the scissor lift assembly 2 by stepping on the control box 8 on the platform 3, so that the operator's hands can perform other tasks at the same time, which further improves work efficiency.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
