Description

Technical Field

[0001] The present application relates to the field of lifting devices, and in particular to a lifting frame. Background Art

[0002] A lifting frame is a platform used to lift workers and goods during the construction of the building's exterior wall. The lifting frame allows workers to be located outside the building's wall to perform construction on the building.

[0003] The lifting frames currently used are mostly of a basket-like structure, that is, they include a base plate and railings arranged on the upper surface of the base plate. The base plate provides a support platform for workers or goods, and the railings are used to enclose the workers on the base plate.

[0004] The lifting frames currently used are mostly supported by connecting slings on the upper side of the railings to realize the lifting of the lifting frame. This results in an unstable position between the lifting frame and the building wall when encountering strong winds and other weather conditions, which can easily cause danger. Utility Model Content

[0005] In order to reduce the phenomenon of horizontal displacement between lifting frame buildings, the present application provides a lifting frame.

[0006] The present application provides a lifting frame adopting the following technical solution:

[0007] A lifting frame comprises a bottom plate, the upper surface of which is fixedly connected with a side plate, the side plate encloses the upper surface of the bottom plate, and a clamping assembly for clamping the building is provided on the side of the side plate close to the adjacent building.

[0008] By adopting the above technical solution and setting up a clamping assembly, when the lifting frame moves to an appropriate position, the clamping assembly can be used to clamp the building on the adjacent side, thereby reducing the horizontal displacement of the lifting frame during construction, resulting in unstable support of the building by the lifting frame, which can cause dangerous phenomena.

[0009] Optionally, the clamping assembly includes two groups of clamping plates arranged opposite to each other, each of the clamping plates is connected to a connecting plate, and each of the connecting plates is slidably inserted into the inside of the side plate close to one side of the building.

[0010] By adopting the above technical solution, when one side of a building needs to be clamped, the connecting plate is moved so that the connecting plate drives the clamping plate to abut against the adjacent building, thereby achieving the process of clamping the building.

[0011] Optionally, each group of the connecting plates is connected to the same driving plate, and the two driving plates are penetrated by and threadedly connected with the same bidirectional lead screw, and the side plate is internally connected with a clamping motor for driving the bidirectional lead screw to rotate.

[0012] By adopting the above technical solution, the clamping motor is started, the clamping motor drives the bidirectional screw to rotate, the bidirectional screw drives the driving plate to move during the rotation, and the driving plate drives the clamping plate to clamp the adjacent building side walls during the movement, thereby reducing the trouble of the staff moving the clamping plate to clamp the building.

[0013] Optionally, a clamping roller is installed on one side of each clamping plate that can abut against the building.

[0014] By adopting the above technical solution and setting up clamping rollers, the clamping plate can be in contact with the building on one side through the clamping rollers during the process of clamping the building. Therefore, when construction needs to be carried out on the building along the vertical direction of the building, the lifting frame can be directly moved, reducing the trouble of controlling the clamping plate to clamp the building multiple times.

[0015] Optionally, a clamping pad is fixedly connected to one side of each clamping plate away from the connected side plate.

[0016] By adopting the above technical solution and providing the clamping pad, the phenomenon of the end of the clamping plate causing wear on the side wall of the building when the clamping plate is used to clamp the side wall of the building is reduced.

[0017] Optionally, the side panel close to the side of the building is installed with a plurality of abutment rollers of which one side can abut against the building.

[0018] By adopting the above technical solution and providing the abutment rollers, the lifting frame can abut against the adjacent wall side walls through the abutment rollers during the movement of the lifting frame in the vertical direction, thereby making the movement of the lifting frame more stable.

[0019] Optionally, an opening penetrating the side panel is provided on the side panel away from the building, and a door panel capable of sealing the opening is installed at the opening.

[0020] By adopting the above technical solution and setting up door panels, the staff can enter the inside of the side panel by opening the door panels when entering and exiting the inside of the side panel. On the one hand, it is convenient for the staff to enter and exit the inside of the side panel, and on the other hand, it can also provide protection for the staff or objects inside the lifting frame.

[0021] Optionally, the lower side of the door panel is rotatably connected to the adjacent bottom panel.

[0022] By adopting the above technical solution, when goods need to be transported, the door panel can be rotated to form a slope between the ground and the upper side of the bottom plate, thereby reducing the labor required by the staff in the process of transporting the goods.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a clamping assembly to clamp the building on one side of the lifting frame, the danger caused by horizontal displacement between the lifting frame and the building during the construction of one side of the building by the workers inside the lifting frame is reduced;

[0025] 2. By providing the clamping roller and the abutting roller, the lifting frame can be stably connected to the side wall of the building when the lifting frame moves in the vertical direction;

[0026] 3. By providing a door panel and making the bottom of the door panel rotatably connected to the bottom panel, it is convenient for workers to enter and exit the inside of the side panel and for carrying goods in and out of the inside of the side panel. BRIEF DESCRIPTION OF THE DRAWINGS

When the lifting frame is located at the position where construction is required, the adjacent building is clamped by the clamping assembly 3, so that the lifting frame can be stably connected to the building on the adjacent side, thereby allowing the staff inside the lifting frame to stably position on one side of the building to perform construction operations on the building.

[0033] By clamping the building body through the clamping assembly 3, the workers can stably stand on one side of the building body to perform construction on the building body.

[0036] When the lifting frame is located at one side of the building, the two-way screw 34 is rotated to drive the two driving plates 33 connected on both sides to move, and each driving plate 33 drives the two connected connecting plates 32 and two clamping plates 31 to move during the movement, so that the two clamping plates 31 on one side of the side plate 2 can clamp the adjacent building side wall, so that the lifting frame can be located at one side of the building and stably connected to the building.

[0037] A clamping motor 4 is provided inside the side panel 2 close to the building body, and a driving gear 41 is fixedly connected to the output shaft of the clamping motor 4. A driven gear 42 is fixedly sleeved at the middle position of the bidirectional lead screw 34, and the driving gear 41 is meshed with the driven gear 42.

[0038] By setting up the clamping motor 4, when it is necessary to clamp adjacent buildings through the clamping assembly 3, the clamping motor 4 is started, the clamping motor 4 drives the driving gear 41 to rotate, the driving gear 41 drives the driven gear 42 to rotate during the rotation, the driven gear 42 drives the connected bidirectional screw 34 to rotate during the rotation, the bidirectional screw 34 drives the four connected clamping plates 31 to clamp the adjacent buildings during the rotation, thereby facilitating the staff to control the process of the clamping plates 31 to clamp the adjacent buildings.

[0039] A clamping roller 311 is installed on one side of each clamping plate 31 close to another corresponding clamping plate 31 in the different group.

[0040] By setting the clamping roller 311, during the process of the clamping plate 31 clamping the building, the staff can adjust the steel cable that drives the lifting frame to move up and down to achieve the vertical movement of the lifting frame, and during the vertical movement, the horizontal position of the lifting frame and the adjacent building can be maintained, which facilitates the staff's processing process of the building in the same vertical direction.

[0041] An end of each clamping plate 31 away from the connected connecting plate 32 is fixedly connected to an abutment pad 312 .

[0042] By providing the abutment pad 312 , the clamping plate 31 can protect the building body abutted by the end portion of the clamping plate 31 during the process of clamping the building body.
