Description

Technical Field

[0001] The invention relates to the technical field of gantry shears, and in particular to a hydraulic gantry shear device with a protective structure. Background Art

[0002] Hydraulic gantry shears are used for shearing various metal plates. They are ideal equipment for processing furnace materials in steel rolling mills, non-ferrous metal plants, and smelters. In the manufacturing industry, for some large plates, due to their high structural hardness and heavy weight, when they need to be sheared, ordinary cutting machines cannot meet the use requirements, but hydraulic gantry shears can meet the use requirements.

[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 it is necessary to use a gantry shear to shear the long steel bars or other steel plates for multiple times. However, when the existing gantry shear shears the steel bars or steel plates, the sheared waste is easy to splash around, thus causing harm to nearby workers, resulting in reduced practicality of the gantry shear. Summary of the invention

[0010] Preferably, the auxiliary unloading mechanism includes a limiting assembly for limiting the rotation of the second rotating plate and a driving assembly for driving the limiting assembly to release the rotation restriction of the second rotating plate, and the driving assembly is connected to the first rotating plate.

[0011] Preferably, the driving assembly includes a support plate fixed on the gantry, a rotating rod rotatably connected to the support plate, a driven gear and a reel arranged on the rotating rod, and an arc-shaped toothed plate fixed to the first rotating plate and meshing with the driven gear, and a pull rope is wound around the reel.

[0012] Preferably, the limiting assembly includes a limiting groove provided on the second placement seat, a limiting block slidably connected in the limiting groove, and a second elastic element arranged between the inner wall of the limiting groove and the limiting block, the end of the pull rope away from the reel passes through the second placement seat and the gantry and is connected to the limiting block, and the bottom wall of the limiting block is provided with an extrusion slope.

[0013] Preferably, an oblique support rod is provided between the first placement seat and the gantry, a material guide plate is fixed on the oblique support rod, and the material guide plate is placed on the lower side of the oblique support rod.

[0014] Preferably, a first scale line is formed on the inner side wall of the second placement seat.

[0015] Preferably, a screw is rotatably connected to the second placement seat, and an extension plate is threadedly connected to the screw, and a second scale line matching the first scale line is formed on the extension plate.

[0016] Compared with the prior art, the present invention provides a hydraulic gantry shear device with a protective structure, which has the following beneficial effects:

[0017] 1. The hydraulic gantry shearing equipment with a protective structure places the sheared material in a placement groove to prevent the sheared material from shaking left and right when being sheared and causing damage to the staff. The auxiliary positioning component temporarily positions the sheared material on the upper side when shearing, without manual pressure, to avoid the sheared parts splashing onto the staff nearby as much as possible, thereby causing injuries to the staff.

[0018] 2. The hydraulic gantry shearing equipment with a protective structure abuts against the movable plate when the positioning seat moves downward, so that the movable plate drives the second elastic telescopic rod and the positioning plate to move downward. Even if the sheared material shakes away from one end of the cutter, the upper positioning plate can temporarily limit the sheared material, and when the positioning plate is subjected to force, the second elastic telescopic rod is stretched, thereby allowing the positioning plate to buffer and unload the swing of the sheared material, thereby avoiding damage to the positioning plate and ensuring the service life of the positioning plate.

[0019] 3. The hydraulic gantry shearing equipment with a protective structure limits the second rotating plate so that when the shearing material can only complete one shearing work at a certain length, the weight of the shearing material on the left side of the cutter is generally greater than the weight on the right side of the cutter. The second rotating plate can support the shearing material that passes over the cutter, and there is no need for the staff to press the shearing material on the right side of the cutter, thereby ensuring the safety of the staff's operation. After the shearing of the shearing material is completed, when the remaining shearing material is not enough to complete one shearing work, the remaining shearing material automatically falls off, and the second rotating plate is no longer limited. At this time, the shearing material on the second rotating plate is unloaded synchronously, ensuring the rapid progress of the shearing work, without the need for manual cleaning by the staff, and reducing the workload of the staff.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Example: Refer to Figure 1 , Figure 2 , Figure 3 and Figure 6A hydraulic gantry shearing device with a protective structure comprises a gantry 1, a hydraulic cylinder 2 is fixedly arranged on the top of the gantry 1, a cutter 3 is connected to the piston rod of the hydraulic cylinder 2, an auxiliary positioning component is arranged on the outer side of the cutter 3, a first placement seat 4 and a second placement seat 5 are respectively arranged on both sides of the gantry 1, a placement groove 6 for placing sheared materials is opened on the first placement seat 4, the second placement seat 5 and the gantry 1, a cutting groove 101 matching with the cutter 3 is opened in the placement groove 6 of the gantry 1, a first rotating plate 401 is rotatably arranged on the first placement seat 4, a second rotating plate 501 is rotatably arranged on the second placement seat 5, and an auxiliary unloading mechanism is arranged between the first rotating plate 401 and the second rotating plate 501.

[0032] Specifically, the sheared material is placed in the placement groove 6, and the sheared material is pushed from the first placement seat 4 to the second placement seat 5. One end of the sheared material passes over the cutter 3. The placement groove 6 limits the two sides of the sheared material to prevent the sheared material from shaking left and right when being sheared and causing damage to the staff. When the hydraulic cylinder 2 drives the cutter 3 to move downward, the auxiliary positioning component works and temporarily positions the upper side of the sheared material when it is sheared. No manual pressure is required, and the sheared parts are prevented from splashing onto the staff nearby as much as possible, thereby causing injuries to the staff.

[0033] Reference Figure 1 , Figure 2 and Figure 3 As a preferred technical solution of the present invention, the auxiliary positioning assembly includes a positioning seat 7 slidably connected to the outside of the cutter 3, a first elastic telescopic rod 701 fixed on the positioning seat 7, and an ear plate 702 connected to the end of the first elastic telescopic rod 701 away from the positioning seat 7, and the ear plate 702 is fixedly connected to the side wall of the cutter 3.

[0034] Specifically, when the hydraulic cylinder 2 drives the cutter 3 to move downward, the cutter 3 drives the positioning seat 7 to move downward through the first elastic telescopic rod 701. The positioning seat 7 first contacts the shear material and presses the shear material downward to fix it. As the cutter 3 continues to move downward, the first elastic telescopic rod 701 is compressed, and the cutter 3 moves downward relative to the positioning seat 7, thereby causing the cutter 3 to shear the shear material pressed and fixed by the positioning seat 7, thereby ensuring the stability of the shear material during shearing and avoiding as much as possible the sheared parts from splashing onto the staff nearby, thereby causing injuries to the staff.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As a preferred technical solution of the present invention, the auxiliary positioning component also includes a groove 8 opened on the first placement seat 4, a movable plate 801 slidably connected in the groove 8, a first elastic element 802 arranged between the bottom wall of the movable plate 801 and the inner wall of the groove 8, a second elastic telescopic rod 803 arranged on the top of the movable plate 801, and a positioning plate 804 connected to the top of the second elastic telescopic rod 803, and the bottom wall of the positioning seat 7 and the top wall of the movable plate 801 are movably abutted against each other.

[0036] Specifically, when the positioning seat 7 moves downward to press and fix the shear material, the bottom wall of the positioning seat 7 presses down on the top wall of the movable plate 801, so that the movable plate 801 drives the positioning plate 804 to move downward through the second elastic telescopic rod 803, so that the positioning plate 804 blocks and limits the upper side of the shear material, and when the positioning plate 804 is subjected to force, the second elastic telescopic rod 803 is stretched, and then the positioning plate 804 buffers and unloads the swing of the shear material, thereby avoiding damage to the positioning plate 804 and ensuring the service life of the positioning plate 804; it should be noted that the height of the positioning plate 804 is not fixed, on the one hand to avoid the spacing between the positioning plate 804 and the bottom wall of the placement slot 6 being too small, affecting the feeding work of the shear material, and on the other hand to avoid the shear material from colliding hard with the positioning plate 804 when swinging, causing damage to the equipment.

[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As a preferred technical solution of the present invention, a first rotating rod 4011 is fixedly provided on the first rotating plate 401, and a first torsion spring placed in the first placement seat 4 is sleeved on the outer side of the first rotating rod 4011; a second rotating rod 5011 is fixedly provided on the second rotating plate 501, and a second torsion spring placed in the second placement seat 5 is sleeved on the outer side of the second rotating rod 5011.

[0038] Furthermore, the auxiliary unloading mechanism includes a limiting assembly for limiting the rotation of the second rotating plate 501 and a driving assembly for driving the limiting assembly to release the rotation restriction of the second rotating plate 501 , and the driving assembly is connected to the first rotating plate 401 .

[0039] Furthermore, the driving assembly includes a support plate 9 fixedly mounted on the gantry 1, a rotating rod 901 rotatably connected to the support plate 9, a driven gear 902 and a drum 903 arranged on the rotating rod 901, and an arc-shaped tooth plate 904 fixedly connected to the first rotating plate 401 and meshing with the driven gear 902, and a pull rope 905 is wound around the drum 903.

[0040] Furthermore, the limiting assembly includes a limiting groove 10 opened on the second placement seat 5, a limiting block 1001 slidably connected in the limiting groove 10, and a second elastic element 1002 arranged between the inner wall of the limiting groove 10 and the limiting block 1001. The end of the pull rope 905 away from the reel 903 passes through the second placement seat 5 and the gantry 1 and is connected to the limiting block 1001. The bottom wall of the limiting block 1001 is provided with an extrusion slope.

[0041] Furthermore, an oblique support rod 11 is provided between the first placement seat 4 and the gantry 1 , and a material guide plate 111 is fixedly provided on the oblique support rod 11 , and the material guide plate 111 is placed on the lower side of the oblique support rod 11 .

[0042] Specifically, when the gantry shears are shearing the sheared material, the sheared material falls from the end of the second rotating plate 501 as the subsequent sheared material is pushed. When the sheared material can only complete one shearing work in length and there is no subsequent shearing material to be fed and pushed, the weight of the sheared material placed on the left side of the cutter 3 is generally greater than the weight of the right side of the cutter 3. The second rotating plate 501 can support the sheared material that has passed the cutter 3, and there is no need for the staff to press the sheared material on the right side of the cutter 3 or lift the end of the sheared material placed on the left side of the cutter 3, thereby ensuring the safety of the staff's operation. After the shearing of the sheared material is completed, when the remaining sheared material is not enough to complete one shearing work, the remaining sheared material presses down the first rotating plate 401 and automatically slides down to the guide plate 111, and finally falls to the aggregate position along the guide plate 111. When the first rotating plate 401 rotates with the first rotating rod 4011 as the center, the arc-shaped tooth plate 904 on the first rotating plate 401 is meshed with the driven gear 902 for transmission, and the driven gear 902 drives the rotating rod 901 and The drum 903 rotates, and the drum 903 reels the pull rope 905. The pull rope 905 pulls the limit block 1001 into the limit groove 10, and the limit block 1001 no longer supports the second rotating plate 501, and the second rotating plate 501 is no longer restricted. At this time, the sheared material on the second rotating plate 501 is discharged synchronously, ensuring the rapid progress of the shearing work, without the need for manual cleaning by the staff, and reducing the workload of the staff. After the sheared material on the first rotating plate 401 falls, the first rotating plate 401 is reset and rotated under the action of the first torsion spring. The arc-shaped toothed plate 904 meshes with the driven gear 902 in the opposite direction, and the limit block 1001 is no longer pulled. The second rotating plate 501 that is reset and rotated under the action of the second torsion spring squeezes the bottom inclined surface of the limit block 1001, and the limit block 1001 avoids the reset of the second rotating plate 501 until the second rotating plate 501 passes over the limit block 1001. The limit block 1001 is reset under the push of the second elastic element 1002 and supports the second rotating plate 501 again, preparing for the subsequent shearing work of the gantry shears.

[0043] Reference Figure 1 , Figure 2 and Figure 3As a preferred technical solution of the present invention, a first scale line 502 is opened on the inner wall of the second placement seat 5.

[0044] Furthermore, a screw rod 12 is rotatably connected to the second placement seat 5 , and an extension plate 13 is threadedly connected to the screw rod 12 . The extension plate 13 is provided with a second scale line 131 that matches the first scale line 502 .

[0045] Specifically, the first scale line 502 set on the second placement seat 5 makes it convenient for the staff to observe the shearing length of the sheared material so that the length of the sheared material can meet the requirements for feeding into the furnace. When the length marked on the first scale line 502 is shorter, the position of the extension plate 13 and the second placement seat 5 is adjusted by rotating the screw 12, and then the overall length of the scale line is adjusted so that the first scale line 502 is matched with the second scale line 131 to meet the requirements of precise shearing size.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
