Description

Technical Field

[0001] The utility model relates to the technical field of section steel straightening devices, in particular to a roll changing sling for a cantilever type straightening machine. Background Technique

[0002] When replacing the working rolls of a cantilever type section steel straightening machine, basically, the upper part of the working rolls is first removed, and then the working rolls are slowly moved out of their working positions by using a traveling crane. When installing the working rolls, the order is reversed.

[0003] The existing roll changing sling for a cantilever type straightening machine, such as the utility model patent with the patent application number CN201621316306.9 and the name of roll changing sling for a cantilever type straightening machine, provides a roll changing sling for a cantilever type straightening machine. It includes a frame, and a plurality of hook lifting holes for keeping the frame balanced when lifting different loads are arranged on the frame. A fixing device for fixedly connecting with one end of the working roll is also arranged on the frame. A first inlet for the end of the working roll to extend into is arranged on the fixing device, and a second inlet for the threaded column at the end of the working roll to extend into is arranged inside the first inlet. A counterweight is also arranged on the frame. The counterweight and the fixing device are respectively arranged on both sides of a plurality of hook lifting holes. The purpose of the utility model is to provide a roll changing sling for a cantilever type straightening machine, which can reduce the labor intensity of workers, reduce the working roll replacement time, and avoid knocking on the working rolls when in use.

[0004] When the above device is in use, the frame is lifted through the lifting holes at different positions of the hooks, so as to facilitate the replacement of the straightening rolls of the straightening machine. However, when replacing the lifting holes, the hooks need to be taken out of the lifting holes, moved to the new lifting holes, and inserted and installed. During this process, due to the heavy weight of the hooks, it is easy to cause fatigue to people, and at the same time, it is time-consuming during this process, affecting the work efficiency, and there are certain deficiencies.

[0005] Therefore, a roll changing sling for a cantilever type straightening machine is provided to solve the above-mentioned problems. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Embodiment:

[0025] Referring to Figures 1-3 , a roll-changing lifting tool for a cantilever straightening machine, including a frame 1, and further including: a mounting bracket 2 fixedly connected to the frame 1; a sliding groove 201 provided in the mounting bracket 2; a sliding rod 4 slidably connected in the sliding groove 201; six groups of welding blocks 3 all fixedly connected to the mounting bracket 2. The six groups of welding blocks 3 are paired in twos, with a total of three pairs arranged on both sides of the sliding groove 201. A clamping groove 301 is provided in the welding block 3, and the clamping groove 301 communicates with the sliding groove 201. The sliding rod 4 can enter the clamping groove 301. The three pairs of welding blocks 3 are all used to keep the frame 1 balanced when the lifting load is different. A fixing device 101 is fixedly connected to the bottom of the frame 1. The fixing device 101 is used to install the straightening roll. A clamping interface 102 is provided on the fixing device 101 for the installation of the straightening roll. A counterweight block 104 is provided at one end of the bottom of the frame 1 away from the fixing device 101. A counterweight frame 103 is fixedly connected to the bottom of the frame 1 at one end away from the fixing device 101, and the counterweight block 104 is installed in the counterweight frame 103.

[0026] In this device, the positions of the three pairs of welding blocks 3 are the same as the positions of the lifting holes in the prior art, and are respectively used to keep the frame 1 balanced when the lifting load is different. The three pairs of welding blocks 3 are the first lifting position, the second lifting position, and the third lifting position respectively.

[0027] Since two sets of straightening rolls, namely the upper straightening roll and the lower straightening roll, need to be installed during use, at this time, the third lifting position is the balance position of the frame 1 when the fixing device 101 is unloaded, the second lifting position is the balance position of the frame 1 when the upper straightening roll is installed on the fixing device 101, and the first lifting position is the balance position of the frame 1 when the lower straightening roll is fixed on the fixing device 101.

[0028] During use, after welding the fixing device 102 to the frame 1, when the straightening roll needs to be replaced subsequently, first loosen the straightening roll to be replaced, and then the hook can be hung on the sliding rod 4. At this time, by moving the sliding rod 4 to the third lifting position, the frame 1 is lifted and moved to the position of the upper straightening roll to be replaced. Affected by the weight, the frame 1 will be in an inclined state. At this time, manual assistance is required, and the upper straightening roll is fixed through the clamping interface 102. The specific fixing method can be fixed by bolts, chains, etc. After the fixing is completed, the device can be moved to the ground by the hook, the straightening roll is taken out from the straightening machine, a new straightening roll is replaced, and it is lifted and moved to the straightening machine for installation.

[0029] When specifically replacing the straightening roll, the steps are the same as above. At this time, there is no need to remove the hook from the sliding rod 4. Just move the sliding rod 4 so that the sliding rod 4 drives the hook to move to the third lifting position. The same as the above steps, take out the lower straightening roll from the straightening machine, move it to the ground, then install a new lower straightening roll and reinstall it.

[0030] After the replacement is completed, the device can be moved to the placement location. At this time, the hook and the sliding rod 4 need to be moved to the second lifting position for transfer. After the placement is completed, the hook can be removed.

[0031] With the lifting position that can be adjusted in the present utility model, during hoisting, there is no need to remove the hook from the lifting hole. Just hang the hook on the sliding rod 4 and move the position of the sliding rod 4 to complete the adjustment of the lifting position. This process is fast and convenient, effectively improving work efficiency and facilitating use.

[0032] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
