Technical Field

[0001] The invention relates to the technical field of steel structure processing, in particular to a steel structure profile hoisting device. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. Its structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The various components of the steel structure are usually connected by welds, bolts or rivets. Because of its light weight and easy and convenient construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other construction fields.

[0003] When installing existing steel structures, they are generally hoisted by hoisting equipment to the corresponding position for installation. Currently, the most common way to hoist steel structures is to use ropes or steel wire ropes to tie the two ends of the steel structure and hang them on hooks or slings for hoisting.

[0004] However, in actual operation, it is difficult to maintain uniform force at all locations of the steel structure when using the above-mentioned lifting method. During the lifting process, the steel structure may easily tilt due to unstable center of gravity, leading to risks such as slipping and disengagement. Summary of the invention

[0005] The purpose of the present invention is to provide a steel structure profile lifting device to solve the problem in the prior art that it is difficult to maintain uniform force at various parts of the steel structure when lifting the steel structure, and the steel structure is prone to tilt due to unstable center of gravity, thereby causing risks such as slipping and disengagement.

A cylinder is fixedly installed in the connection box, and the end of the piston rod of the cylinder passes through the connection box and the equipment base, and a connecting block is fixedly installed on the end of the piston rod, and the left and right ends of the connecting block are respectively installed with a first rack; two groups of rotating shafts are installed on the equipment base, and the two groups of rotating shafts are symmetrically arranged along the central axis of the equipment base, and each group of rotating shafts includes a first rotating shaft and a second rotating shaft arranged in a horizontal direction, and the first rotating shaft is arranged close to the connection block, and a half gear is coaxially connected to the first rotating shaft, and the tooth portion of the half gear is meshed with the first rack; the second rotating shaft and the non-tooth portion of the half gear are respectively connected with support rods, and the bottom ends of the two support rods are hinged with an L-shaped frame, and a clamping plate is installed on the frame.

[0007] The technical principle of this solution is: when hoisting the steel structure, the clamping mechanism is moved to the steel structure to be hoisted by supporting the boom and lifting the hoisting cable. According to the size of the steel structure to be hoisted, the position distance of the control device plate is moved along the slide slot so that the clamping plate can be in a suitable position on the steel structure.

[0008] Start the cylinder, and the piston rod on the cylinder drives the connecting block to move. The first racks on the left and right ends of the connecting block respectively engage with the two half gears and drive the two half gears to rotate, and then drive the two brackets to move through the support rod, so as to achieve the clamping and fixing effect of the two clamping plates on the steel structure, which is convenient for the final lifting work.

Through the meshing between the first full gear and the second rack, the two equipment plates can move towards or in the opposite direction, so that the equipment plates can be in the best position for hoisting the steel structure.

[0012] As a preferred technical solution of the present invention: an arc-shaped limit plate is fixedly installed on the plate surface of the clamping plate. The arc-shaped limit plate can achieve a better clamping effect on the steel structure.

[0013] As a preferred technical solution of the present invention: a support rod is movably installed at the bottom of the clamping plate. The support rod can effectively prevent the clamped and fixed steel structure from slipping.

[0014] By adopting the above technical solution, the beneficial effects of the present invention are:

By moving the position distance of the equipment plate in the slideway, the clamping plate can be placed in a suitable position on the steel structure according to the size of the steel structure to be hoisted, so that the range of hoisting the steel structure is wider and the effect is better.

[0016] 2. The gas in the cylinder is cleverly used to fill the air pipe, which increases the air pressure in the air pipe, thereby driving the push rod to slide. The third rack on the push rod can drive the second full gear to rotate, and finally realize the movement effect of the equipment plate. Only one power source is used to realize the operation of multiple mechanisms at the same time, which greatly saves resource investment.

[0017] 3. By setting arc-shaped limit plates, support rods and other structures on the clamping plate, the limiting and fixing effect of the hoisted steel structure is effectively guaranteed, effectively avoiding dangerous problems such as slipping and unhooking. BRIEF DESCRIPTION OF THE DRAWINGS
