Description

Technical Field

[0001] The utility model belongs to the technical field of gantry shears, in particular to a side thrust device of a gantry shears. Background Art

[0002] Gantry shears are heavy-duty cutting equipment. Their main function is to cut waste steel and other waste materials into sizes that are easy to recycle. Gantry shears are generally composed of a pusher, a presser and a cutting device. The cutting principle of gantry shears is to use a cutter to cut steel and other materials in a vertical direction. The pressure during cutting must be large enough for fast cutting. The shearing knife directly separates the waste material to be cut into two parts during the forward process, with a smooth cut and high precision.

[0003] However, the existing gantry shear pushing device pushes the waste materials to the shear knife for cutting. Although the longitudinal size of the waste materials is shortened, the lateral size is still large, which does not meet the needs of subsequent transportation and processing. This solution solves this technical problem. Utility Model Content

[0004] The utility model aims to provide a gantry shear side-pushing device, which solves the technical problem that the existing gantry shears handle waste materials that are too large in size and cannot meet the needs of later transportation and processing. The hydraulic cylinder drives the side-pushing block to compress the waste materials, so that the lateral size of the waste materials is reduced. After being sheared once by the shear knife, the size can meet the needs of later transportation and processing.

[0005] The gantry shear side-thrust device includes support seats respectively arranged at both ends of one side of the gantry scissors frame, and also includes a fixed plate connected to one end of the support seat, a hydraulic cylinder connected to the fixed plate at a fixed end, and a side-thrust block connected to the telescopic end of the hydraulic cylinder. The side-thrust block includes a vertical plate connected to the telescopic end of the hydraulic cylinder on one side, and a plurality of limit columns connected to the top of the vertical plate. The limit columns of the two side-thrust blocks are cross-arranged, and the other side of the vertical plate and the side where the limit columns intersect with each other are both provided with wear-resistant linings.

[0006] A plurality of grooves are vertically opened on the other side of the vertical plate, and a pressure roller is rotatably arranged in the groove. The roller shaft of the pressure roller is connected to a driving motor. The pressure roller is made of rubber, and the outer side surface of the pressure roller protrudes from the outer side surface of the wear-resistant lining.

[0007] A plurality of grooves 2 are provided on one side of the limiting column, guide rollers are rotatably arranged in the grooves 2, and the outer side surfaces of the guide rollers protrude from the wear-resistant lining plate.

[0008] Support plates connected to the main body of the gantry shears are respectively arranged on both sides of the support seat, and the support seat is connected to the main body of the gantry shears by bolts.

[0009] A cover plate is arranged on the top side of the support seat, and the cover plate is connected with the support seat by bolts.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] (1) Side push blocks connected to the telescopic end of the hydraulic cylinder are provided at both ends of one side of the gantry scissor frame. The side push blocks are connected to the telescopic end of the hydraulic cylinder. The side push blocks include vertical plates and limit columns. Both the vertical plates and limit columns are provided with wear-resistant linings. When the telescopic end of the hydraulic cylinder is extended, the waste materials are squeezed and compacted by the wear-resistant linings of the side push blocks, thereby reducing the lateral size of the waste materials, so that the waste materials can meet the requirements of later transportation and processing after one-time cutting and processing;

[0012] (2) The side push block is provided with limit columns, and the limit columns are cross-arranged. When the waste material is compressed, the limit columns are close together and cross-arranged, so that when the waste material is compressed, it is prevented from being compressed and deformed, resulting in bulging and detaching from the push device, and the compression process of the waste material is safer;

[0013] (3) A pressure roller is arranged in the groove 1 of the vertical plate. The pressure roller is made of rubber. The rotation of the pressure roller drives the waste material forward together with the pushing device. The waste material is guided by the guide roller in the groove 2 of the limiting column, so that the transportation of the waste material is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

The side-thrust block 4 includes a vertical plate 41 connected to the telescopic end of the hydraulic cylinder 3 on one side, and a plurality of limiting columns 42 connected to the top of the vertical plate 41. The limiting columns 42 of the two side-thrust blocks 4 are cross-arranged, and the other side of the vertical plate 41 and the side where the limiting columns 42 intersect with each other are both provided with a wear-resistant lining plate 43.

[0022] A plurality of grooves 411 are vertically opened on the other side of the vertical plate 41 , and a pressure roller 412 is rotatably arranged in the groove 411 . The roller shaft of the pressure roller 412 is connected to a driving motor. The pressure roller 412 is made of rubber, and the outer side surface of the pressure roller 412 protrudes from the outer side surface of the wear-resistant lining plate 43 .

[0023] A plurality of grooves 421 are formed on one side of the limiting column 42 . Guide rollers 422 are rotatably disposed in the grooves 421 , and the outer side surfaces of the guide rollers 422 protrude from the wear-resistant lining plate 43 .

[0024] Support plates 5 connected to the main body of the gantry shears are respectively arranged on both sides of the support base 1, and the support base 1 is connected to the main body of the gantry shears by bolts.

[0025] A cover plate 6 is provided on the top side of the support seat 1 , and the cover plate 6 is connected to the support seat 1 by bolts. The cover plate 6 is connected to the support seat 1 by bolts, so that the hydraulic cylinder 3 can be easily maintained after the cover plate 6 is removed.

[0026] The specific working process of this utility model:

[0027] When in use, the waste material is first transported to the side of the tool holder 7 through the pushing device 8, and the end of the waste material is located between the two side pushing blocks 4 of the side pushing device. The hydraulic cylinder 3 is started, and the hydraulic cylinder 3 extends and drives the two side pushing blocks 4 to approach and close together. The waste material first contacts the pressure roller 412. Since the pressure roller 412 is made of rubber, the pressure roller 412 is pressed to the inside of the groove 1 411. The hydraulic cylinder 3 continues to push the side pushing block 4, so that the waste material contacts the wear-resistant lining plate 43, and the wear-resistant lining plate 43 preliminarily compresses the waste material.

[0028] The side push block 4 continues to move, and the limiting columns 42 of the side push blocks 4 on both sides begin to come together and cross. The closing and crossing of the limiting columns 42 prevents the waste material from being compressed and deformed, causing it to bulge and fall away from the pushing device 8. The compression of the waste material is safer. The waste material is compressed to a set size, reducing the lateral size of the waste material. Then, the hydraulic cylinder 3 is slightly retracted to a certain distance, so that the waste material is separated from the wear-resistant lining plate 43 and the pressure roller 412 is in contact with the waste material.

[0029] The pushing device 8 is started, and the motor connected to the pressure roller 412 is started at the same time. The motor drives the pressure roller 412 to rotate, and the pressure roller 412 generates friction with the waste material. The pushing device 8 and the pressure roller 412 drive the waste material to move forward to the position of the scissor frame 7. The guide roller 422 reduces the friction of the waste material movement. Then the pushing device 8 and the motor stop moving. The waste material is cut by the scissor device of the scissor frame 7. The horizontal and vertical dimensions of the waste material after one cutting meet the requirements of later transportation and processing. There is no need to cut it again, and the processing of the waste material is convenient and quick.

[0030] The pusher device 8 is prior art and will not be described in detail here.

[0031] Technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be elaborated here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
