Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a high-leg suspended platform device. Background Technology

[0002] Suspended platforms are construction machinery used for high-altitude operations in building engineering, such as curtain wall installation and exterior wall decoration. The cantilevered mechanism is erected on a building or structure, and a lifting mechanism drives the suspended platform. Because some high-rise buildings have very high parapet walls, standard suspended platform cantilever frames cannot be used. Instead, extended and heightened non-standard cantilever frames are used. These non-standard cantilever frames have a lower safety factor and are prone to safety risks such as leg deformation. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a high-leg suspended platform device with a simple structure and reasonable design. It shortens the length of the front column and improves the flexibility of the rear column, thereby reducing the risk of deformation of the front and rear support structures. It eliminates the need to connect the heavy boom through holes, reducing the difficulty of assembly and disassembly. The middle pulley support seat is inverted and fits into the boom, hugging the load-bearing part of the boom with the bracket, thus strengthening the load-bearing part of the boom.

[0004] To achieve the above objectives, this utility model provides a high-support leg suspended platform device, including a front support structure and a rear support structure. The front support structure is located at the top of the parapet wall, and the rear support structure is located at the top of the highest floor. A boom is connected to the top of the front and rear support structures. The front end of the boom extends out of the front support structure, forming a lever structure with a short arm from the front end of the boom to the top of the front support structure and a long arm from the top of the front support structure to the top of the rear support structure. A front pulley seat is provided at the front end of the boom, and a front pulley is movably connected to the front pulley seat.

The bracket groove supports and connects the boom.

[0008] The front column or rear main column is made of 100×100×4 square tube, and the top connecting column is made of 90×90×4 square tube.

[0009] The top connecting column is inserted into the top of the front column or the rear main column, and the front column or the rear main column is bolted to the top connecting column.

[0010] Furthermore, the rear support includes a base, a rear bottom column is connected to the middle of the base, and counterweight positioning rods are provided on both sides of the rear bottom column on the base, the counterweight positioning rods being connected to counterweight blocks;

[0011] The base is made of 100×40×4 square tubing;

[0012] The rear bottom column is made of 100×100×4 square tube. The top of the rear bottom column is connected to the bottom of the rear main column. A bottom connecting column is sleeved at the connection between the rear bottom column and the rear main column. The bottom connecting column is made of 90×90×4 square tube.

[0013] The rear bottom column, the rear main column, and the bottom connecting column are all provided with through holes on their front and rear sides, and are connected by bolts through the through holes.

[0014] Furthermore, the intermediate pulley seat includes an intermediate pulley support seat, which is an inverted groove-shaped component. The intermediate pulley support seat is inverted and attached to the upper side of the boom, and the intermediate pulley support seat and the support groove hug the boom. An intermediate pulley column is connected to the upper side of the intermediate pulley support seat, and a reinforcing plate is provided between the intermediate pulley column and the intermediate pulley support seat.

An inclined rear pulley connecting plate is connected to the upper side of the rear pulley support seat, and the end of the rear pulley connecting plate is connected to the rear pulley.

[0016] The beneficial effects of this scheme can be seen from the description above. It has a simple structure, reasonable design, and the following advantages:

[0017] (1) The length of the front column was shortened and a cross brace was added between the rear main columns to avoid the risk of the front column and the rear main columns being distorted and deformed;

[0018] (2) The rear bottom column and the rear main column are connected by square tubes of the same specifications, and the connection is fitted with a tightly connected square tube, thereby improving the flexibility of the connection.

[0019] (3) The middle pulley support and the rear pulley support are inverted on the boom, so that the boom can be installed and disassembled simply by placing it directly on the bracket, without having to pass the heavy and long boom through the hole, thus simplifying the installation and disassembly process;

[0020] (4) The middle pulley support is upside down on the boom, and then the middle pulley column is welded to the middle pulley support. This avoids the welding operation on the stress concentration part of the boom, thus avoiding the impact on the strength of the boom. In addition, the middle pulley support and the bracket hug the stress part of the boom, strengthening the strength of the stress part of the boom. Attached Figure Description
