Description

Technical Field

[0001] This utility model relates to the field of construction hoisting machinery technology, and more specifically, to a construction hoist attachment frame angle adjustment device. Background Technology

[0002] Construction hoists are construction lifting machinery frequently used in construction for carrying people and goods. Their stability mainly depends on the reliable connection between the attachment frame and the building structure. In order to ensure the overall verticality and stress stability of the guide frame, each attachment frame adopts the same installation spacing, and the tilt angle or elevation angle of the attachment frame must be within 8°.

[0003] Traditional attachment frame installation methods typically involve anchoring the standard section to the guide rail frame using U-bolts or other types of bolts on the upper, middle, and lower frames. However, in actual construction, due to factors such as complex building structures, construction errors, and limited anchoring positions, the fixed angle design of traditional attachment frames is difficult to adapt to different working conditions. This leads to the need for customized modifications during installation or the installation of an additional attachment device, which significantly increases construction costs and time. Utility Model Content

[0006] As a further improvement to the technical solution of this utility model, the outer walls of the two edges of the adjustment frame are provided with a plurality of first connecting holes at equal intervals along the vertical direction on the inner side of the two adjustment connecting seats, and the upper and lower ends of the adjustment connecting seats are provided with second connecting holes.

[0008] As a further improvement to the technical solution of this utility model, the connecting convex plate is welded and fixed to the outer wall of the adjusting connecting seat, the end rod of the attachment frame is connected to the connecting convex plate by bolts, and the attachment frame and the connecting convex plate are both provided with a third connecting hole for the bolt to pass through.

[0009] As a further improvement to the technical solution of this utility model, the support and strengthening mechanism includes a horizontal plate fixedly connected to the bottom of the adjusting connecting seat. A screw is connected vertically to the inside of the end of the horizontal plate below the outer side of the connecting convex plate. A handwheel is fixedly connected to the bottom of the screw, and a lifting plate is connected to the end of the screw above the horizontal plate. A limiting vertical rod is fixedly connected to the bottom of the lifting plate in the vertical direction, and the bottom of the limiting vertical rod extends to the bottom of the horizontal plate.

[0010] As a further improvement to the technical solution of this utility model, a bearing seat is installed at the bottom of the lifting plate corresponding to the end position of the screw, and a silicone pad is adhered to the upper surface of the lifting plate.

[0011] As a further improvement to the technical solution of this utility model, the interior of the horizontal plate is provided with an internal thread hole that matches the external thread structure of the screw, and the interior of the horizontal plate is provided with a through hole for limiting the passage of the vertical rod.

[0012] The beneficial effects of this utility model are: 1. This utility model addresses the drawback of the non-adjustable connection angle of traditional hoist attachment frames by conducting technical research on the connection method and structure of construction hoist attachment frames. This enables the connection angle of construction hoist attachment frames to be adjustable, effectively improving the reliability and safety of hoist attachment frame connections, minimizing rework due to angle deviations and unnecessary additional installations, and ensuring that the guide rail frame always maintains good verticality and stability. 2. By setting up a support and reinforcement mechanism, after the attachment frame is connected, the screw is rotated by turning the handwheel, and then the guide limit rod is used to limit the lifting plate to maintain a stable vertical rise, and then contact the lower surface of the attachment frame to provide support. The silicone pad can reduce the wear between the attachment frame and the lifting plate when under force, and thus can provide a stable support effect after the attachment frame is connected, and it is not easy to deflect under force.

[0022] As attached Figure 1-4As shown, the connecting convex plate 3 is welded and fixed to the outer wall of the adjusting connecting seat 2. The end rod of the attachment frame 4 is connected to the connecting convex plate 3 by bolts. The attachment frame 4 and the connecting convex plate 3 are both provided with a third connecting hole 301 for bolts to pass through, which facilitates the connection and disassembly between the attachment frame 4 and the connecting convex plate 3 on the outer wall of the adjusting connecting seat 2.

A screw 502 is vertically connected to the inner end of the horizontal plate 501, located below the outer side of the connecting protrusion 3.

The connecting square tube on the adjusting frame 1 can be connected and fixed to the standard section by connecting bolts through the connecting holes on the frame in the standard section. The adjusting frame 1 is designed with multiple first connecting holes 101 for connecting the adjusting connecting seat 2. The corresponding installation hole position can be selected according to the actual building conditions and the installation position of the attachment seat to ensure that the pitch angle of the attachment frame is kept within ±8°, thereby further ensuring the verticality of the guide rail frame and realizing the smooth operation of the elevator. By setting the support reinforcement mechanism 5, after the attachment frame 4 is connected, the screw 502 is rotated by rotating the handwheel 503, and then the guide limit of the limiting vertical rod 505 is used to keep the lifting plate 504 stable in the vertical direction, and then contact the lower surface of the attachment frame 4 to provide support.
