Description

Technical Field

[0001] The utility model belongs to the technical field of crop shears related equipment, in particular to a crop shears blade trolley. Background Art

[0002] In the existing medium and thick plate production line, the crop shear is a key equipment widely used in the transverse shearing of steel plates. With the advancement of the industrial efficiency-oriented development model, the operating frequency of the equipment has been significantly improved compared with the past. This high frequency of use has led to an increasing frequency of blade replacement of the crop shear, which in turn poses new challenges to the continuous and efficient operation of the production line.

[0003] In the traditional shear blade replacement process, there is often a problem of excessive deflection of the shear blade trolley beam caused by the breaking of the side fastening screws. Once the beam of the shear blade trolley is excessively deflected, it is very easy to get stuck with other parts of the head shear equipment, resulting in the shear blade trolley being unable to move out smoothly. This situation not only greatly increases the difficulty of shear blade replacement, but also significantly prolongs the time required for replacement, thereby affecting the operating efficiency of the entire production line.

[0004] Although there are some solutions to the above problems in the industry, most of them are either complicated to operate or costly and are difficult to be widely used in actual production. Therefore, how to effectively solve the problem of excessive beam deflection caused by the broken side fastening screws of the shearing trolley during the replacement of the shearing blade, reduce the difficulty and time cost of shearing blade replacement, and improve the overall operation efficiency of the production line has become an important issue that needs to be solved in the current technical development of medium and thick plate production lines.

[0027] Preferably, both ends of the lower shear blade box 4 are respectively fixed to the fixed side vehicle beam and the movable side vehicle beam by side fastening bolts 4-1. The side fastening bolts ensure the connection strength and stability between the lower shear blade box and the vehicle beam, and prevent loosening or displacement due to vibration or impact during replacement.

[0028] Preferably, supporting pins 3-1 are provided at both ends of the upper shear blade box 3, and upper open placement grooves are provided on the fixed side beam and the movable side beam. Supporting pins are provided at both ends of the upper shear blade box and are placed in the placement grooves. The matching design of the supporting pins and the placement grooves improves the assembly accuracy of the upper shear blade and provides a guarantee for the head shears to receive, position and lock the upper shear blade.

[0029] Preferably, the fixed side beam includes a fixed side beam body 1-1, a traction part 1-2 is provided at one end of the fixed side beam body, a first blade box connecting plate 1-3 perpendicular to the fixed side beam body is provided at the other end of the fixed side beam, the lower blade box is connected to the first blade box connecting plate by side fastening bolts; the first blade box connecting plate is provided with a first placement groove 1-4 for placing the upper blade box end support pin.

[0031] The process of replacing the shear blade is described as follows:

[0032] Adjust the upper blade position: First, adjust the upper blade of the head shear to the lowest position, and ensure that the upper blade box is just above the center of the shear trolley beam. This step is to align the position of the upper blade box and the shear trolley to prepare for the subsequent blade replacement.

[0033] Loosen the connection lock: Next, the operator needs to loosen the locking nut, which is to release the connection between the upper and lower shear boxes and the shears. After loosening, the upper shear box can fall freely onto the shear trolley below.

[0034] Lift the lifting beam: Then, lift the lifting beams on both sides to keep the wheels of the shear trolley parallel to the track. The purpose of this step is to ensure that the shear trolley can move smoothly and avoid jamming or friction caused by the wheels not being parallel to the track.

[0035] Place the mobile support wheels: After confirming that the shear trolley wheels are parallel to the track, the operator needs to place the mobile support wheels of the shear trolley under the end of the shear box where the shear head is cut. The addition of the mobile support wheels provides additional support for the shear trolley, helping to maintain stability during the pull-out process.

[0036] Pull out the shear trolley: Next, pull the shear trolley loaded with old shears out of the crop shears equipment by pulling the trolley. During the pulling out process, the mobile support wheels play a key supporting and sliding role to ensure that the shear trolley can be moved out smoothly and easily.

[0037] Replace the new shear blade: Finally, push the shear blade trolley carrying the new shear blade into place, lower the lifting beam and the upper shear blade of the shear, tighten the locking nut with the shear, and complete the shear blade replacement. The installation of the new shear blade also requires ensuring that the connection between the upper and lower shear blade boxes and the shear blade equipment is tight and stable to ensure the performance and safety of the shear blade in subsequent use.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
