Description

Technical Field

[0001] The utility model relates to the technical field of hoisting, in particular to a device for quickly hoisting steel components. Background Art

[0002] Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses, etc. made of steel sections and steel plates. It is widely used because of its light weight and simple construction. At present, when hoisting steel structures, rope loops and lifting clamps are usually used to lift steel components. During the lifting process, the steel components need to be fixed by rope loops to prevent them from slipping. The fixing process is very cumbersome, and the rope loop is easily worn by the edge of the steel structure due to long-term use, making the rope loop easy to break and causing safety accidents. When the lifting clamp is in use, it is easy to get out of the clamp, which poses a safety hazard. For this reason, we propose a device for quickly lifting steel components. Utility Model Content

[0003] The utility model aims to provide a device for quickly lifting steel components, so as to solve the problem that the traditional lifting device is easy to slip and inconvenient to fix when used in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The basic technical solution provided by the utility model is: a device for quickly lifting steel components, comprising a left lifting clamp and a right lifting clamp, the left lifting clamp is rotatably connected with the right lifting clamp, the left lifting clamp and the right lifting clamp are provided with slots, the left lifting clamp and the right lifting clamp are composed of two clamping plates connected by a connecting block, and locking components are arranged on the left lifting clamp and the right lifting clamp.

[0006] Principle of the basic technical solution: The utility model clamps the steel structure through the notches provided on the left lifting clamp and the right lifting clamp to lift the steel structure. The left lifting clamp and the right lifting clamp are rotatably connected, and the distance between the notches of the left lifting clamp and the right lifting clamp can be controlled to adapt to steel members of different widths. The locking components provided on the left lifting clamp and the right lifting clamp prevent the left lifting clamp and the right lifting clamp from loosening, thereby improving the safety of lifting.

[0007] Preferably, a connecting tube is provided between the two clamping plates on the left hanging clamp, a limiting block is provided on the connecting tube, the left hanging clamp and the right hanging clamp are connected by a third bolt, and a third locking nut is provided on the third bolt.

[0008] Through the above-mentioned arrangement, the left lifting clamp and the right lifting clamp are connected by a third bolt so that the left lifting clamp and the right lifting clamp can rotate, and the angle between the left lifting clamp and the right lifting clamp can be adjusted to adapt to steel components of different sizes. Two limit blocks are provided on the connecting tube, and a limit groove is formed between the two limit blocks. During lifting, the hook or the lifting rope is limited to avoid sliding of the hook or the lifting rope on the connecting tube, thereby ensuring stability during lifting.

[0009] Preferably, the locking assembly includes a first bolt, a second bolt and a screw rod, the first bolt and the second bolt are respectively passed through the left hanging clamp and the right hanging clamp, the first bolt and the second bolt are respectively provided with a first locking nut and a second locking nut, the first bolt and the second bolt are respectively provided with a first threaded barrel and a second threaded barrel, and the first threaded barrel and the second threaded barrel are passed through a screw rod.

[0010] Through the above arrangement, the screw is inserted into the first bolt and the second bolt, which fixes the left and right lifting clamps, thereby preventing the third locking nut from loosening during the lifting process of the left and right lifting clamps, causing the left and right lifting clamps to loosen and create a safety hazard.

[0011] Preferably, the notch is inclined upward.

[0012] The above arrangement makes it convenient to clamp and fix the steel member.

[0013] Preferably, the notch is provided with saw teeth.

[0014] Through the above arrangement, the saw teeth can increase the friction between the steel components and prevent the steel components from slipping and causing safety hazards.

[0015] Preferably, the outer circumferences of the left and right hanging clamp bodies are rounded transitionally.

[0016] The above arrangement can avoid damage to the steel components caused by collision during lifting. BRIEF DESCRIPTION OF THE DRAWINGS
