Description

Technical Field

[0001] This utility model relates to the technical field of galvanizing steel pipes, and in particular to a galvanized steel pipe discharge device. Background Technology

[0002] After the steel pipes are galvanized, they need to be removed from the galvanizing bath and transported to a cooling system for cooling. For example... Figure 1 As shown, this is a discharge device above a steel pipe galvanizing tank, including a mounting box 1 and conveyor rollers 3. A support block 11 is provided on one side of the mounting box 1, and the support block 11 is fixed to the ground. The mounting box 1 is fixed to the support block 11. The conveyor rollers 3 are rotatably connected to the bottom of the mounting box 1. Multiple conveyor rollers 3 are evenly distributed at the bottom of the mounting box 1. Adjacent conveyor rollers 3 are connected by a first chain group 16. A drive motor for driving one of the conveyor rollers 3 is fixed to the top of the mounting box 1. A protective cover 4 is provided on the outside of the first chain group 16.

[0003] A galvanizing tank 2 is set up on the ground, and a lifting assembly is installed on the ground to lift the steel pipes inside the galvanizing tank 2. A retaining block 21 is fixed on one side of the galvanizing tank on the ground. After galvanizing, the steel pipes are taken out of the galvanizing tank 2 by the lifting assembly and then conveyed by conveyor rollers 3. The steel pipes will drop molten zinc, which falls onto the retaining block 21 and the ground to form zinc billets. Workers will regularly clean the zinc billets on the ground and put them back into the galvanizing tank 2.

[0004] Since the two conveying rollers 3 are connected by the first chain group 16, the bottom of the first chain group 17 is lower than the bottom of the mounting box 1. The space between the bottom of the first chain group 16 and the protective cover 4 and the upper surface of the baffle block 21 is limited, making it inconvenient for workers to clean the zinc billet on the upper surface of the baffle block 21. Furthermore, the protective cover 4 and the first chain group 16 will obstruct the workers' view, making it difficult for them to observe the conveyed steel pipe. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present invention provides a galvanized steel pipe discharge device.

[0006] This utility model provides a galvanized steel pipe discharge device, which adopts the following technical solution:

[0007] A galvanized steel pipe unloading device includes an inclined mounting box, a galvanizing pool on the ground, one end of the mounting box being directly above the galvanizing pool, the side of the mounting box closer to the galvanizing pool being lower, a baffle block fixed on the ground, the top surface of the baffle block being inclined, the side of the top surface of the baffle block closer to the galvanizing pool being lower, a first mounting block fixed at the bottom of the mounting box, a conveyor roller rotatably connected between two first mounting blocks, multiple fixed shafts fixed on the side wall of the mounting box, each fixed shaft corresponding to a conveyor roller, a second chain group being arranged between the conveyor roller and the fixed shaft, one end of the chain in the second chain group being higher than the bottom of the mounting box, and a third chain group being arranged between two adjacent fixed shafts, the bottom of the chain in the third chain group being higher than the bottom of the mounting box.

[0008] Optionally, the side wall of the mounting box is provided with a protective cover that encloses the second chain group and the third chain group. The protective cover includes a top plate and a side plate. The top plate is fixed to the side wall of the mounting box, the top of the side plate is hinged to the top plate by a hinge, and the bottom of the side plate is higher than the bottom of the mounting box.

[0009] Optionally, the side wall of the mounting box is provided with a locking assembly to secure the side panel.

[0010] Optionally, the locking assembly includes a locking rod with a cuboid abutment block threaded onto its outer wall. An elongated hole is provided on the side plate, through which the locking rod passes. The abutment block is located on the outside of the side plate and abuts against it. When the length direction of the abutment block is consistent with the length direction of the elongated hole, the abutment block can pass through the elongated hole.

[0011] Optionally, the bottom of the mounting box is provided with a support roller for supporting the steel pipe. The support roller is located between two adjacent conveying rollers. The two ends of the support roller are rotatably connected to a second mounting block. The second mounting block is fixed to the bottom of the mounting box. A third mounting block is provided on one side of the second mounting block. The third mounting block is fixed to the bottom of the mounting box. A guide sleeve is rotatably connected to the bottom of the third mounting block. The steel pipe passes between the two guide sleeves.

[0012] Compared with the prior art, the present invention has the following technical effects:

[0013] Because the chain of the third chain group is higher than the bottom of the mounting box, and only one end of the chain of the second chain group is lower than the bottom of the mounting box, this invention allows for a clearer view of the conveyed steel pipe compared to existing technologies where the chain is lower than the bottom of the mounting box. It also provides greater operating space for workers to clean the zinc billets on the inclined surface of the retaining block, facilitating their operation. The guide sleeve can limit the movement of the steel pipe, ensuring stable conveying. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 2 -Appendix Figure 5 The present invention will be described in further detail below.

[0021] Reference Figures 2-5 This utility model discloses a galvanized steel pipe discharge device, including a mounting box 1. Two support blocks 11 are provided on one side of the mounting box 1, and the bottom of the support blocks 11 is fixed to the ground. A fixing block 12 is fixed to the top of the first mounting block 31, and the fixing block 12 is fixed to the top of the mounting box 1. The mounting box 1 is inclined and forms a certain angle with the ground. A galvanizing tank 2 is provided on the ground. The side of the mounting box 1 closer to the galvanizing tank 2 is lower, and the side of the mounting box 1 farther away from the galvanizing tank 2 is higher.

[0022] The bottom of the mounting box 1 is provided with multiple conveying rollers 3, which are evenly distributed along the length of the first mounting block 31. Each conveying roller 3 has a first mounting block 31 at both ends, and the first mounting block 31 is fixed to the bottom of the mounting box 1. The two ends of the conveying roller 3 are rotatably connected to the first mounting block 31 respectively.

[0023] A fixed shaft 13 is fixed to the side wall of the mounting box 1. The fixed shaft 13 is located above the first mounting block 31. Each conveyor roller 3 corresponds to one fixed shaft 13. The fixed shaft 13 and the conveyor roller 3 are connected by a second chain group 14. Adjacent fixed shafts 13 are connected by a third chain group 15. The second chain group 14 includes two sprockets and a chain. One sprocket is fixedly connected to the conveyor roller 3, and the other sprocket is fixedly connected to the fixed shaft 13. The chain is mounted on the two sprockets. The third chain group 15 has the same structure as the second chain group 14. A motor 17 that drives one of the fixed shafts 13 is fixed to the top of the mounting box 1. The motor 17 is connected to the fixed shaft 13 by a chain. The chain of the third chain group 15 is higher than the bottom of the mounting box 1, while the chain of the second chain group 14 is lower than the bottom of the mounting box 1 only at one end.

[0024] A protective cover 4 is installed on the side wall of the mounting box 1, which encloses the second chain assembly 14 and the third chain assembly 15. The protective cover 4 includes a top plate 41 and a side plate 42. The top plate 41 is fixed to the mounting box 1, and the side plate 42 is hinged to the top plate 41. A locking assembly 5 is provided on the side wall of the mounting box 1 to secure the protective cover 4. When the side plate 42 is in the vertical position, the bottom of the side plate 42 is higher than the bottom of the mounting box 1.

[0025] The lower side of the mounting box 1 is located directly above the galvanizing tank 2. A baffle block 21 is fixed on the ground. The baffle block 21 is located on the higher side of the galvanizing tank 2, closer to the mounting box 1. When the steel pipe in the galvanizing tank 2 is taken out and transported, the molten zinc will fall onto the top surface of the baffle block 21. The top surface of the baffle block 21 is tilted downwards towards the galvanizing tank 2. Some of the molten zinc that falls onto the baffle block 21 will flow into the galvanizing tank 2, and some of the molten zinc will solidify on the upper surface of the baffle block 21 to form a zinc billet. The workers will clean the zinc billet regularly and put it back into the galvanizing tank 2.

[0026] Because the chain height of the third chain group 15 is higher than the bottom of the mounting box 1, and only one end of the chain of the second chain group 14 is lower than the bottom of the mounting box 1, this invention allows for a clearer view of the conveyed steel pipe compared to the prior art where the chain is lower than the bottom of the mounting box 1. Furthermore, it provides greater operating space for workers to clean the zinc billets on the inclined surface of the retaining block 21, facilitating their operations.

[0027] A lifting assembly 6 is installed on the ground, which can remove the galvanized steel pipe from the galvanizing bath 2. The lifting assembly 6 includes a hydraulic cylinder 61, a rotating shaft 62, a connecting rod 63, and a lifting rod 64.

[0028] The end of the hydraulic cylinder 61 is hinged to the ground, and a connecting block 65 is fixed on the ground. The rotating shaft 62 is rotatably connected to the connecting block 65. One end of the connecting rod 63 is hinged to the piston rod of the hydraulic cylinder 61, and the other end of the connecting rod 63 is hinged to the rotating shaft 62. The end of the rotating shaft 62 away from the connecting rod 63 faces the galvanizing tank 2 and is located directly above the galvanizing tank 2.

[0029] The lifting rod 64 is located inside the galvanizing tank 2, with one end fixed to the rotating shaft 62. A lifting block 66 is fixed to the other end of the lifting rod 64, which lifts the steel pipe inside the galvanizing tank 2. When the piston rod of the hydraulic cylinder 61 retracts, the lifting rod 64 lifts the steel pipe inside the galvanizing tank 2, bringing it into contact with the conveyor roller 3. The steel pipe is then sandwiched between the conveyor roller 3 and the lifting block 66, creating friction between them. As the conveyor roller 3 rotates, it drives the steel pipe forward.

[0030] A support roller 7 is located at the bottom of the mounting box 1, between two adjacent conveying rollers 3. Second mounting blocks 71 are rotatably connected to both ends of the support roller 7, and these second mounting blocks 71 are fixed to the bottom of the mounting box 1. The support roller 7 supports the conveyed steel pipe. A third mounting block 81 is located on one side of the second mounting block 71, and is fixed to the bottom of the mounting box 1. A guide sleeve 8 is rotatably connected below the third mounting block 81, through which the steel pipe passes, and the guide sleeve 8 limits the movement of the steel pipe. A fixing bolt 82 is located below the third mounting block 81, threadedly connected to it, and the guide sleeve 8 is fitted onto the fixing bolt 82.

[0031] The locking assembly 5 includes a locking rod 51, with an abutment block 52 threaded onto its outer wall. One end of the locking rod 51 is fixed to the side wall of the mounting box 1. The abutment block 52 is cuboid in shape. An elongated hole 53 is provided on the side plate 42, through which the locking rod 51 passes. The position of the elongated hole 53 corresponds to the position of the external abutment block 52. When the length direction of the abutment block 52 is aligned with the length direction of the elongated hole 53, the abutment block 52 can pass through the elongated hole 53. The abutment block 52 is located outside the side plate 42.

[0032] Before locking and fixing the protective cover 4, the side plate 42 is first in a horizontal state. First, rotate the abutment block 52 so that the vertical direction corresponds to the length direction of the elongated hole 53. Then, put the side plate 42 down so that the abutment block 52 passes through the elongated hole 53. When the side plate 42 is in a vertical state, tighten the abutment block 52 and make the abutment block 52 and the elongated hole 53 at a certain angle so that the abutment block 52 abuts against the side plate 42.

[0033] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
