Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, and specifically, to a lift device with adjustable angle. Background Art

[0002] A lift is a commonly used auxiliary machine in construction. It can drive the entire operation platform to rise and fall, and can quickly transport personnel and materials in a short time, greatly improving the work efficiency of construction. The scissor lift is one of the most common lifts. Its lifting mechanism is made of high-strength manganese steel rectangular tubes. It is equipped with a safety protection device to prevent the lift from overloading. It is equipped with a safety protection valve to prevent the hydraulic pipeline from bursting. It is equipped with an emergency descent device in case of power failure. In order to meet more usage requirements, it is necessary to adjust the angle of inclination of the lift device.

[0003] For example, Chinese Patent CN215101748U discloses a hydraulic lift with an angle adjustment function, which includes a lift main body and an inclination angle adjustment component located at the bottom of the lift main body. The inclination angle adjustment component includes a first support structure and a second support structure for supporting the lift main body, and the distance between the positions where the first support structure and the second support structure contact the ground is adjustable. It effectively improves the convenience of using the lift. However, during the use of the above lift, its inclination angle is adjusted by setting a second support structure at the bottom end of the lift. Adjusting the inclination angle of the lift at the bottom end will cause the center of gravity of the lift to shift too much. Especially when the load is large or the objects on the platform are unevenly distributed, the center of gravity shift may cause the lift to tilt or overturn, increasing the safety risk.

In construction, this angle-adjustable lift device can quickly and safely move objects or personnel from one height to another, thereby improving work efficiency, and can adjust the angle of the working platform according to requirements to adapt to different work tasks and environments.

[0035] In one embodiment, for the above-mentioned adjusting workbench mechanism 4, the adjusting workbench mechanism 4 includes a support plate 401 arranged at the top end of the top plate 3. Above the support plate 401, there is a platform cover plate 402. At both ends and on both sides inside the bottom end of the platform cover plate 402, vertical rods 403 are symmetrically arranged. At the bottom end of the vertical rod 403, there is a cross rod 404; a placing cylinder 405 is arranged through the bottom end of the support plate 401. In addition, in specific applications, the bottom end of the placing cylinder 405 penetrates the bottom end of the top plate 3, and the placing cylinder 405 is connected to the top plate 3 through a bearing. At the bottom end inside the placing cylinder 405, there is a first movable component 406. At the top end of the first movable component 406, there is a hydraulic telescopic rod 407. At the top end of the hydraulic telescopic rod 407, there is a second movable component 408; at both ends and on both sides of the top end of the support plate 401, there are fixed seats 409. On one side of the fixed seat 409, there is an auxiliary component 410; the first movable component 406 and the second movable component 408 have the same structure, and the second movable component 408 includes a first U-shaped seat 4081 arranged at the top end of the piston rod of the hydraulic telescopic rod 407. Inside the first U-shaped seat 4081, there is a rotating ball 4082.

At the top end of one end of the mounting seat 4101, there is an electric telescopic rod 4102. At one end of the piston rod of the electric telescopic rod 4102, there is a pressing plate 4103 that penetrates one side of the mounting seat 4101 and matches the cross rod 404, and the cross section of the pressing plate 4103 is an L-shaped structure; the top end of the second movable component 408 is fixedly connected to the inner top end of the platform cover plate 402, thereby realizing the adjustment of the inclination angle of the lift during use. And by adjusting the angle inclination at the top of the lift device, the center of gravity can be relatively low, the overall structure is more stable, the risk of tipping is reduced. At the same time, the operator can more accurately control the inclination angle, avoid sudden inclination and imbalance conditions, and ensure the safety of the operation.

[0036] In addition, it should be noted that the size of the cross-section at the top end of the above-mentioned support plate 401 is smaller than the size of the cross-section at the bottom end of the platform cover plate 402 to ensure the stability of the platform cover plate 402 during the tilting process.

[0038] The working principle of the adjustment workbench mechanism 4 is as follows: When the tilting angle of the platform cover plate 402 does not need to be adjusted, the piston rod of the four groups of electric telescopic rods 4102 is used to drive the pressing plate 4103 to move, and the cross bar 404 is limited by the pressing plate 4103 to ensure the stability of the platform cover plate 402. When the tilting angle of the platform cover plate 402 needs to be adjusted, the piston rod of the three groups of electric telescopic rods 4102 is controlled to drive the pressing plate 4103 to move, so that the three pressing plates 4103 no longer limit the cross bar 404. Then, the piston rod of the hydraulic telescopic rod 407 drives the movable component 408 to move, and then the platform cover plate 402 can be driven to rotate around the cross bar 404 in the other set of limits, thereby realizing the angle adjustment of the platform cover plate 402.

[0039] In one embodiment, for the above-mentioned driving mechanism, the driving mechanism includes a mounting frame 701 provided at the bottom end of the top plate 3. A motor 702 is provided at the inner bottom end of the mounting frame 701. A first gear 703 is provided at the top end of the output shaft of the motor 702.

[0040] The working principle of the driving mechanism is as follows: The motor 702 drives the first gear 703 to rotate, and then drives the placing cylinder 405 to rotate under the meshing action of the first gear 703 and the second gear 704, thereby realizing the rotation of the adjustment workbench mechanism 4 in the horizontal direction.

[0041] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0042] In actual application, first, move the lift device to the area to be used, then adjust the lift through the scissors support 2, and according to the usage requirements, adjust the tilting angle of the top end of the lift device through the adjustment workbench mechanism 4, and then the rotation angle of the top end of the lift device in the horizontal direction can be adjusted through the driving mechanism.

[0043] In summary, by means of the above technical solutions of the present utility model, the structure of the present utility model is reasonable and reliable. In the aspect of building construction, the angle-adjustable lift device can quickly and safely move objects or personnel from one height to another, thereby improving work efficiency, and can adjust the angle of the working platform according to requirements to adapt to different work tasks and environments; by setting the adjusting workbench mechanism 4, the inclination angle adjustment of the lift during use is realized, and by adjusting the angle at the top of the lift device, the center of gravity can be relatively low, the overall structure is more stable, the risk of tipping is reduced, and at the same time, the operator can more accurately control the inclination angle to avoid sudden inclination and imbalance conditions, ensuring the safety of the operation; by setting the driving mechanism, the rotation of the adjusting workbench mechanism 4 in the horizontal direction is realized, enabling the lift device to meet different usage requirements during use, thereby improving the versatility of the lift device during use.
