Description

Technical Field

[0001] The utility model relates to the technical field of steel structure hoisting equipment, in particular to a balance sling for rapid hoisting of steel columns in a steelmaking workshop. Background Technique

[0002] At present, in the process of installing some workshops, steel structures are often used as supporting components. At the same time, the steel column structures of the workshops are mostly double-limb lattice stepped columns, which need to be fabricated in segments and transported to the site for hoisting of the upper and lower columns.

[0003] However, in the prior art, when some existing large-scale hoisting equipment hoists steel structures, problems such as hoisting eccentricity and hoisting imbalance are likely to occur and are difficult to adjust. As a result, the hoisting position deviates from the installation position, increasing the installation difficulty. In addition, it is also easy to occur that the steel structure tilts and slides during hoisting. At the same time, when some hoisting equipment hoists the steel structure, it is not convenient to quickly fix the steel structure, so it needs to be solved. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art: when some existing large-scale hoisting equipment hoists steel structures, problems such as hoisting eccentricity and hoisting imbalance are likely to occur and are difficult to adjust. As a result, the hoisting position of the hoisted steel structure deviates from the installation position, increasing the installation difficulty. In addition, it is also easy to occur that the steel structure tilts and slides during hoisting. At the same time, when some hoisting equipment hoists the steel structure, it is not convenient to quickly fix the steel structure, so it needs to be solved.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a balance sling for rapid hoisting of steel columns in a steelmaking workshop, including: a support frame and two mounting blocks; a circular groove opened on the inner wall at the center of the support frame; and further including:

[0006] A semi-circular plate is movably embedded in the circular groove. A connecting rod is fixedly installed on the top surface of the semi-circular plate, and a hoisting block is fixedly installed on the top surface of the connecting rod.

[0007] Two long rods are fixedly installed on the surfaces of the two mounting blocks away from the support frame. One side surface of one of the mounting blocks is fixedly installed on the surface of the support frame. Long grooves are opened on the surfaces of the two long rods away from the support frame.

[0008] Two mounting frames II are fixedly installed on one side surfaces of the two long rods. Driving motors II are fixedly installed on one side surfaces of the two mounting frames II, and a bidirectional screw rod is fixedly installed on the output end surfaces of the two driving motors II.

[0009] Preferably, one end of each of the two bidirectional screw rods is movably embedded in the long groove, and clamping claws are sleeved on the outer surfaces of the symmetric parts of the two bidirectional screw rods in a threaded manner.

[0010] The technical effect of adopting the above further scheme is that: the bidirectional screw rods are positioned through the long groove, and at the same time, when the bidirectional screw rods rotate, the clamping claws on the surface are driven to move in position.

[0011] Preferably, one end of each of the plurality of clamping claws is slidably embedded in the long groove, and connection blocks are fixedly installed at the symmetric parts on the top surface of the support frame.

[0012] The technical effect of adopting the above further scheme is that: the clamping claws are limited through the long groove, and at the same time, the support frame fixes the connection blocks on the surface.

[0013] Preferably, steel cables are arranged at one ends of the two connection blocks, and one ends of the two steel cables are fixedly connected to the symmetric parts on the surface of the hoisting block.

[0014] The technical effect of adopting the above further scheme is that: the two ends of the steel cables are respectively connected to the surfaces of the connection blocks to disperse the load and avoid local stress concentration.

[0015] Preferably, counterweight blocks are fixedly installed at the symmetric parts on the outer surface of the support frame, and a sliding groove is formed in one side surface of the support frame.

[0016] The technical effect of adopting the above further scheme is that: due to the weight of the counterweight blocks on the surface of the support frame, the two ends of the support frame are kept balanced when not working, and at the same time, a sliding groove is formed in the surface of the support frame, which is convenient for the installation of internal parts.

[0017] Preferably, an installation frame one is fixedly installed on one side surface of the support frame, and a driving motor one is fixedly installed on the inner wall of one side of the installation frame one.

[0018] The technical effect of adopting the above further scheme is that: the driving motor one is fixed through the installation frame one on the surface of the support frame, and when the driving motor one works, it drives the parts connected to the output to rotate.

[0019] Preferably, a threaded rod is fixedly installed on the output end surface of the driving motor one, and one end of the threaded rod is threadedly embedded in the surface of another installation block.

[0020] The technical effect of adopting the above further scheme is that: when the driving motor one works, it drives the threaded rod to rotate, so that the installation block on the outer surface moves in position.

[0021] Preferably, the outer surface of another installation block is slidably embedded in the sliding groove, and a counterweight is fixedly installed on the surface of another long rod.

[0022] The technical effect of adopting the above further solution is: the installation block is limited by the chute to prevent skewing, and at the same time, the counterweight on the surface is moved when the long rod moves.

[0023] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0024] 1. In the present utility model, during use, the semi-circular plate is limited by the circular groove opened inside the support frame. At the same time, the top surface of the semi-circular plate is connected to the lifting block through a connecting rod. When cooperating with a lifting device, the lifting block can be moved. At the same time, both ends of the steel cable are respectively connected to the surfaces of the lifting block and the connecting block to disperse the load and avoid local stress concentration. At the same time, the supplementary weight block arranged on the surface of the support frame keeps the support frame balanced on both sides with the semi-circular plate as the fixed point. When the driving motor 1 on one surface of the mounting frame works, it drives the threaded rod on the surface of the output end to move inside the chute, and drives the mounting block on the outer surface of the mounting frame 1 to move inside the chute, and drives the counterweight on the surface of the long rod to move, so as to keep it balanced with the other end, facilitating the later docking and installation work.

[0025] 2. In the present utility model, one of the mounting blocks is fixed by the support frame, and at the same time, the mounting frame 2 on the surface of the long rod fixes the driving motor 2. When the driving motor 2 works, it drives the bidirectional screw rod on the surface of the output end to rotate inside the long groove, and drives the clamping claws symmetrically arranged on the surface to move towards the middle. At the same time, the clamping claws are slidably embedded inside the long groove for limiting work. Through the meshing of two clamping claws, the steel member can be quickly fixed, facilitating transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In this embodiment, during use, the semi-circular plate 1011 is limited by the circular groove 101 formed inside the support frame 1. Meanwhile, the top surface of the semi-circular plate 1011 is connected to the lifting block 1013 through the connecting rod 1012.

At the same time, both ends of the steel cable 1014 are respectively connected to the surfaces of the lifting block 1013 and the connecting block 1015 to disperse the load and avoid local stress concentration. Meanwhile, the weight compensation block 103 arranged on the surface of the support frame 1 keeps the support frame 1 balanced on both sides with the semi-circular plate 1011 as the fixed point. When the driving motor 1041 on the surface of the mounting frame 104 works, it drives the threaded rod 1042 on the surface of the output end to move inside the sliding groove 102, and drives the mounting block 2 on the outer surface of the mounting frame 104 to move inside the sliding groove 102, and drives the weight block 204 on the surface of the long rod 201 to move, so as to keep it balanced with the other end, facilitating the later docking and installation work.

At the same time, the two ends of the steel cable 1014 are respectively connected to the surface of the lifting block 1013 and the connecting block 1015 to disperse the load and avoid local stress concentration. At the same time, the supplementary weight block 103 set on the surface of the support frame 1 keeps the support frame 1 balanced on both sides with the semicircular plate 1011 as the fixed point. When the driving motor 1041 on the surface of the mounting frame 104 works, it drives the threaded rod 1042 on the output end surface to move inside the slide groove 102, driving the mounting frame 104 outside The mounting block 2 on the surface moves inside the slide groove 102, driving the counterweight block 204 on the surface of the long rod 201 to move, so that it maintains balance with the other end, which is convenient for the later docking and installation work.
