Embodiment Construction

[0014] 1. Design, production and installation of ring chains: commonly used chains in machinery include welded ring chains, figure-eight chains, hook chains, etc. Due to the welded ring chain (3), the structure is simple, convenient to manufacture, economical, and suitable for Conditions of heavy load. Made as figure 1 , image 3 The ring chain (3) in, the chain size: diameter d is 7mm, pitch t is 21, width B is 24, load test is 0.8 tons, load failure is 1.6 tons, material is A2 or A3, and welding ring is used. The chain (3) is more than enough for the lifting load of the minecart.

[0015] 2. There are two types of ring chains: rough and refined. You can choose one of the two. Because the number of sections used is small and the price is low, refined ones can be used. According to the design requirements, they can be purchased on the market.

[0016] 3. The connection of the ring chain with the hook and the wire rope is like figure 1 , figure 2 with image 3 Shown, not repeat th...

Abstract

The invention discloses an anti-slip safety device for a tower crane hook. The device is a hook safety device, namely an annular chain when the tower crane lifts bricks, stone materials and the like; several sections of annular chains are connected to a hook head of the hook and the other end is connected with a steel wire rope pulley; and the device is simple in structure, convenient to manufacture, economic, and applicable to higher-load conditions. Due to a certain pitch between the annular chains, the movable space is wider between the sections, the device has higher flexibility, the chains play a role in buffering under the action of extrusion in four sides, the device guarantee the safety, and personal injury and death accidents due to unhooking are prevented and avoided. The device adopts not less than five sections of annular chains, and coarse and fine chains can be used; and another device is a latch enclosed hook, in the process of hanging and unloading the hook, an elastic movable latch is pressed manually only, the chain can be put in, and after the hand is loosened, the latch automatically seals a locking port under the action of a spring force so as to prevent unhooking.

Description

Technical field [0001] The invention relates to an anti-falling safety device for a tower crane hook. [0002] A tower crane hook anti-falling safety device, which is a hook connection device for building tower crane lifting materials-an endless chain. It is convenient and fast, especially safe. With it, it is safe to prevent and avoid unhooking personal injuries during lifting. . Background technique [0003] At present, the known tower crane hooks all hang the hooks of the hooks on the wire rope pulleys, and the hooks are directly hooked on the slings of the bins for transporting bricks and stone materials. The steel wire rope swings greatly from time to time, just like the principle of the balance wheel in physics, especially if it swings up and down and jumps up and down, the masonry contained in the material box will sometimes be thrown from high altitude. In the event of a hook unhooking accident, the material will be damaged at the slightest level, and the material will be...
