Description

A tower crane hook anti-fall structure

Technical Field

The utility model relates to the technical field of tower crane hooks, in particular to a tower crane hook anti-falling structure.

Background Art

Tower crane is also called tower crane, which originated in Western Europe. It is a rotating crane with the boom installed on the top of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, boom, base and lifting hook, among which the lifting hook is one of the important parts of the crane and is often used to lift heavy objects.

When the existing lifting hook is used for lifting and transportation, it has an opening and the lifting rope carrying the load needs to be hung in the hook for lifting. Since the hook generally adopts an opening and arc-shaped design, during the lifting process, if the hook is tilted or shaken, it will cause the rope to be unhooked, posing a safety hazard. For this reason, we propose a tower crane hook anti-fall structure.

Utility Model Content

The utility model aims to provide a tower crane hook anti-falling structure to solve the problems raised in the above-mentioned background technology.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tower crane hook anti-fall structure, including a hook seat, the bottom end of the hook seat is connected to the hook, and an anti-fall pile is arranged inside the bottom end of the hook, the anti-fall pile includes a pile body, and a pressure block is arranged at the top middle end of the pile body, the bottom end of the pressure block is connected to a compression spring rod, and slide grooves are distributed on both sides of the pressure block, anti-slip heads are attached to both sides of the bottom end of the pressure block, and springs are connected to both sides of the anti-slip heads.

Furthermore, the anti-slipping heads are symmetrically distributed along both sides of the pressing block, and one end of the anti-slipping head is in an inclined fit with both sides of the pressing block.

Furthermore, the pressure block forms an elastic structure with the pile body through a spring, and the other end of the anti-slip head is arranged equidistantly along the openings on both sides of the pile body.

Furthermore, the hook seat includes a seat frame, and plate frames are fixedly connected to both sides of the seat frame. An axle rod is opened in the middle of the bottom end of the plate frame, and the middle end of the axle rod is connected to a connecting frame, and the bottom end of the connecting frame is fixedly connected to a hook.

Furthermore, the seat frame and the plate frame are integrally fixedly connected, and the connecting frame forms a rotating structure with the seat frame through an axle rod.

Furthermore, the hook includes a hook frame, and the bottom end of the hook frame is connected to a hook, the outer wall of the hook is distributed with anti-slip grooves, and a pile body is arranged inside the hook.

Furthermore, the hook frame and the hook are integrally fixedly connected, and anti-slip grooves are equidistantly arranged along the outer wall around the hook.

Compared with the prior art, the beneficial effect of the utility model is that the anti-fall pile is placed inside the hook, and the gravity generated when the lifting rope is hung and lifted exerts pressure on the pressure block, thereby cooperating with the downward pressure of the pressure block to extrude the anti-slip heads on both sides, forming a process of positioning the lifting rope on both sides of the hook, thereby increasing the friction force and positioning points, reducing the risk of the lifting rope detaching and falling during transportation, and improving safety.

When this anti-fall structure is in use, it is connected to the hook through the connecting frame at the bottom of the seat frame, and the shaft rod connected to the top of the connecting frame keeps rotating with the seat frame, which is convenient for adaptation and adjustment during the lifting process and provides flexibility in lifting, mounting and detaching.

The hook of this anti-fall structure is composed of a hook frame and an integrated hook. When the hook is used for hanging and lifting, the lifting rope can be hung on the inner wall of the hook. During the lifting process, the anti-slip groove design arranged on the surface can improve the friction with the lifting rope surface, thereby improving the stability of the hanging process.

DETAILED DESCRIPTION

As shown in Figure 1, a tower crane hook anti-fall structure includes a hook seat 1, the bottom end of the hook seat 1 is connected to a hook 2, and an anti-fall pile 3 is arranged inside the bottom end of the hook 2, the hook seat 1 includes a seat frame 101, and both sides of the seat frame 101 are fixedly connected to a plate frame 102, a shaft rod 103 is opened in the middle of the bottom end of the plate frame 102, and the middle end of the shaft rod 103 is connected to a connecting frame 104, the bottom end of the connecting frame 104 is fixedly connected to the hook 2, the seat frame 101 and the plate frame 102 are fixedly connected as a whole, and the connecting frame 104 forms a rotating structure with the seat frame 101 through the shaft rod 103. When this anti-fall structure is used, the connecting frame 104 at the bottom end of the seat frame 101 is connected to the hook 2 for use, and the shaft rod 103 connected to the top end of the connecting frame 104 keeps rotating with the seat frame 101, which is convenient for adaptation and adjustment during lifting, and provides lifting, mounting and detachment flexibility.

As shown in Figure 2, a tower crane hook anti-fall structure is provided, the hook 2 includes a hook frame 201, and the bottom end of the hook frame 201 is connected to a hook 202, the outer wall of the hook 202 is provided with anti-skid grooves 203, and the interior of the hook 202 is provided with a pile body 301, the hook frame 201 and the hook 202 are integrally fixedly connected, and the anti-skid grooves 203 are equidistantly arranged along the outer wall around the hook 202, the hook 2 of this anti-fall structure is composed of the hook frame 201 and the integrated hook 202, when the hook 2 is mounted and hoisted, the lifting rope can be mounted on the inner wall of the hook 202, and the friction with the surface of the lifting rope can be improved through the slotted design of the anti-skid grooves 203 arranged on the surface during the hoisting process, thereby improving the stability of the mounting process.

As shown in Figure 2-3, a tower crane hook anti-fall structure is shown, the anti-fall pile 3 includes a pile body 301, and a pressure block 302 is arranged at the top middle end of the pile body 301, the bottom end of the pressure block 302 is connected to a compression spring rod 303, and slide grooves 304 are distributed on both sides of the pressure block 302, anti-slip heads 305 are attached to both sides of the bottom end of the pressure block 302, and springs 306 are connected to both sides of the anti-slip heads 305. This anti-fall pile 3 is arranged inside the hook 202, and the gravity generated when the lifting rope is hung and lifted is used to apply pressure to the pressure block 302, so that the downward pressure of the pressure block 302 cooperates with the anti-slip heads 305 on both sides to extrude, forming a process of positioning the lifting rope on both sides of the hook 202, thereby improving the friction and positioning points, reducing the hidden dangers of the lifting rope detaching and falling during transportation, and improving safety.

Working principle: When the tower crane is used to lift items, the hook seat 1 connected to the crane can be lowered first, and then the operator will hang the lifting rope with the lifted goods on the inner wall of the hook 202. During the lifting process, the friction between the lifting rope and the surface can be increased through the slotted design of the anti-slip grooves 203 arranged on the surface. After lifting, the lifting rope will form pressure on the top surface of the pressure block 302 with the gravity of the goods. At this time, the pressure block 302 presses down and squeezes the anti-slip heads 305 attached to the bottom ends of both sides out of the two sides of the hook 202 at an inclination angle, thereby vertices the lifting rope body and maintains stable lifting.
