Description

Technical Field

[0001] The invention relates to the technical field of shearing equipment, and in particular to a bulk scrap hydraulic gantry shearing equipment. Background Art

[0002] Bulk scrap steel refers to metal fragments and debris discarded by the metallurgical industry and metal processing industry, as well as metal objects scrapped during equipment renewal. It also includes metal packaging containers and scrapped vehicles recycled from urban garbage. Scrap metal is also a resource. Countries around the world have specialized units engaged in the recycling and utilization of scrap metal businesses. The recycled scrap metal is mainly used for smelting and converted into recycled metal, and some is used to produce machinery and equipment or parts, tools and civil appliances.

[0003] In the recycling process of bulk scrap steel, due to the presence of long steel bars or other steel plates, it is not convenient to put them into the furnace, so the long steel bars or other steel plates need to be sheared multiple times by gantry shears. However, after the existing gantry shears shear the steel bars or steel plates, the cut steel bars or steel plates still have a certain length, and the sheared materials are often placed downward at the end away from the gantry shears, causing the sheared materials to be tilted when they fall, affecting the placement of the subsequent sheared materials, resulting in disordered accumulation of sheared materials, occupying too much material collection space, and increasing the transfer cycle of the sheared materials by the staff. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to propose a bulk scrap hydraulic gantry shearing device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] Preferably, the displacement assembly includes a movable groove opened on the gantry, a reciprocating screw rotatably connected in the movable groove, a sleeve threadedly connected to the reciprocating screw, and a connecting rod fixed on the sleeve, and the end of the connecting rod away from the sleeve is connected to the material receiving box.

[0012] Preferably, a hook is movably connected to one end of the connecting rod away from the sleeve, a hanging rod matched with the hook is provided on the material receiving box, and a roller is provided at the bottom of the material receiving box.

[0016] Compared with the prior art, the present invention provides a bulk scrap hydraulic gantry shearing device, which has the following beneficial effects:

[0017] 1. The bulk scrap hydraulic gantry shearing equipment can lower the sheared materials horizontally by setting auxiliary unloading components, and the displacement components drive the receiving box to move back and forth, so that the sheared materials are evenly stacked in the receiving box, ensuring the receiving amount of the sheared materials by the receiving box, reducing the transfer cycle of the sheared materials and the difficulty of subsequent sorting of the sheared materials by the staff.

[0018] 2. The hydraulic gantry shearing equipment for bulk scrap steel makes the upper cutting seat consist of a cutter and a positioning seat that are elastically connected. When the piston rod of the hydraulic cylinder drives the cutter to move downward, the cutter drives the positioning seat to move downward through the elastic telescopic rod. The upper cutting seat first contacts the bulk scrap steel on the upper side of the cutting groove through the positioning seat. The positioning seat presses the bulk scrap steel downward to position it, thereby ensuring stability during shearing of the bulk scrap steel. As the upper cutting seat continues to move downward, the cutter moves relative to the positioning seat, thereby causing the cutter to shear the bulk scrap steel in the positioning position, thereby ensuring shearing quality.

[0030] Example: Refer to Figure 1 , Figure 3 and Figure 4 A hydraulic gantry shearing device for bulk scrap steel comprises a gantry 1, a hydraulic cylinder 2 is fixedly arranged on the top of the gantry 1, a piston rod of the hydraulic cylinder 2 is connected with an upper cutting seat 3, a cutting groove 101 is opened at the bottom of the gantry 1 located at the upper cutting seat 3, a placing plate 4 is arranged on one side of the gantry 1, two groups of auxiliary unloading components are arranged on the side of the gantry 1 away from the placing plate 4, a material receiving box 5 is slidably connected to the gantry 1, the material receiving box 5 is arranged on the lower side of the auxiliary unloading component, and a displacement component for driving the material receiving box 5 to move back and forth is arranged on the gantry 1.

[0031] Specifically, the bulk scrap steel is placed on the placement plate 4, and the bulk scrap steel is moved to the side away from the placement plate 4 until the distance from the end of the bulk scrap steel to the cutting groove 101 meets the shearing size, and then the hydraulic cylinder 2 is controlled to operate, and the piston rod of the hydraulic cylinder 2 drives the upper cutting seat 3 to move downward, so that the upper cutting seat 3 shears the bulk scrap steel, and the bulk scrap steel is cut off from the cutting groove 101, and the auxiliary unloading component causes the sheared material to be lowered horizontally, and the displacement component drives the receiving box 5 to move back and forth, so that the sheared material is evenly stacked in the receiving box 5, ensuring the receiving amount of the sheared material by the receiving box 5, reducing the transfer cycle of the sheared material and the difficulty of subsequent sorting of the sheared material for the staff.

[0032] Reference Figure 1 , Figure 3 and Figure 4 As a preferred technical solution of the present invention, a feeding channel 6 for placing bulk materials is provided on the gantry 1 and the placement plate 4, a groove 101 is provided in the feeding channel 6 of the gantry 1, and a belt conveyor 601 is provided in the feeding channel 6 of the placement plate 4; specifically, the feeding channel 6 can limit the two sides of the bulk scrap steel, and the belt conveyor 601 transports the bulk scrap steel from the feeding channel 6 until the length of the bulk scrap steel after passing the position of the groove 101 meets the shearing size, and then the belt conveyor 601 stops transporting the bulk scrap steel.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As a preferred technical solution of the present invention, the upper cutting seat 3 includes a cutter 301 fixedly connected to the piston rod of the hydraulic cylinder 2, a positioning seat 302 slidably connected to the outside of the cutter 301, a side plate 303 fixedly arranged on the outside of the cutter 301, and an elastic telescopic rod 304 arranged between the side plate 303 and the positioning seat 302; specifically, when the piston rod of the hydraulic cylinder 2 drives the cutter 301 to move downward, the cutter 301 drives the positioning seat 302 to move downward through the elastic telescopic rod 304, and the upper cutting seat 3 first contacts the bulk scrap steel on the upper side of the cutting groove 101 through the positioning seat 302, and the positioning seat 302 presses the bulk scrap steel downward to position it, thereby ensuring the stability of the bulk scrap steel during shearing, and as the upper cutting seat 3 continues to move downward, the cutter 301 moves relative to the positioning seat 302, so that the cutter 301 shears the bulk scrap steel in the positioning, thereby ensuring the shearing quality.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As a preferred technical solution of the present invention, the auxiliary unloading assembly includes a first rod body 7 and a second rod body 701 fixed on the gantry 1, a support plate 702 rotatably connected to the outside of the first rod body 7, and an elastic telescopic plate 703 rotatably connected to the outside of the second rod body 701, and one end of the elastic telescopic plate 703 away from the second rod body 701 is movably connected to the lower side of the support plate 702.

[0035] Furthermore, the auxiliary blanking assembly also includes an auxiliary plug rod 8 fixedly mounted on the outside of the cutter 301 , and a plug hole 801 movably connected to the auxiliary plug rod 8 is formed on the support plate 702 .

[0036] Specifically, when the piston rod of the hydraulic cylinder 2 drives the upper cutting seat 3 to move downward to shear the bulk scrap steel, the auxiliary insertion rod 8 connected to the upper cutting seat 3 is inserted into the insertion hole 801 of the support plate 702 to limit the support plate 702. The support plate 702 can temporarily support one end of the bulk scrap steel during the shearing process to prevent the end of the bulk scrap steel away from the placement plate 4 from sagging due to shearing until the bulk scrap steel is completely sheared. Then the hydraulic cylinder 2 drives the upper cutting seat 3 to move upward and reset, and the auxiliary insertion rod 8 is away from the support plate 702. The support plate 702 is no longer restricted, and the support plates 702 on both sides of the gantry 1 automatically deflect downward under the downward pressure of the sheared material, so that both ends of the sheared material are lowered at the same time, and then the sheared material is lowered horizontally, thereby preventing the sheared material from being placed at an angle when it falls.

[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, the displacement assembly includes a movable groove 9 opened on the gantry 1, a reciprocating screw 901 rotatably connected in the movable groove 9, a sleeve 902 threadedly connected to the reciprocating screw 901, and a connecting rod 903 fixed on the sleeve 902, and the end of the connecting rod 903 away from the sleeve 902 is connected to the material receiving box 5.

[0039] Furthermore, a guide rod 10 is fixedly provided on the outside of the cutter 301 , and the guide rod 10 is slidably connected to the gantry 1 . A rack plate 1001 is fixedly provided on the bottom of the guide rod 10 , and a one-way gear 12 meshing with the rack plate 1001 is provided on the reciprocating screw 901 .

[0040] Furthermore, the one-way gear 12 includes a fixed wheel 121 connected to the reciprocating screw rod 901 and a driven gear 122 rotatably connected to the outside of the fixed wheel 121. The fixed wheel 121 is provided with a groove 1211, and a block 1212 is rotatably connected to the groove 1211 through a pin shaft. The pin shaft is provided with a torsion spring for driving the block 1212 to reset and rotate. The inner wall of the driven gear 122 is provided with grooves 1221 evenly distributed in a circle, and the block 1212 is movably connected in the groove 1221.

[0041] Specifically, when the piston rod of the hydraulic cylinder 2 drives the upper cutting seat 3 to move downward to shear the bulk scrap steel, the upper cutting seat 3 drives the rack plate 1001 to move downward through the guide rod 10, so that the rack plate 1001 is meshed with the one-way gear 12 on the reciprocating screw rod 901 for transmission, and the driven gear 122 is engaged with the clamping block 1212, so that the one-way gear 12 drives the reciprocating screw rod 901 to rotate, and the sleeve 902 moves axially along the reciprocating screw rod 901, so that the sleeve 902 drives the material receiving box 5 to move horizontally through the hook 9031 at the end of the connecting rod 903, and when the upper cutting seat 3 drives the rack plate 1001 to move upward through the guide rod 10, the inner wall of the driven gear 122 The block 1212 is squeezed and shrinks in the groove 1211. The driven gear 122 will not drive the fixed wheel 121 and the reciprocating screw 901 connected to the fixed wheel 121 to rotate. Only when the upper cutting seat 3 continues to move downward, the one-way gear 12 will drive the reciprocating screw 901 to rotate, so that the sleeve 902 moves back and forth along the axial direction of the reciprocating screw 901, so that the sheared material falls evenly into the material receiving box 5, avoiding the sheared material from being concentrated and accumulated in one place of the material receiving box 5, ensuring the material receiving capacity of the material receiving box 5 for the sheared material. When the sheared material in the material receiving box 5 needs to be transported, the hook 9031 can be removed from the hanging rod 9032.
