Description

Technical Field

[0001] This utility model relates to the field of steel pipe sorting technology, specifically to a steel pipe sorting and conveying device. Background Technology

[0002] To improve or eliminate structural defects and residual stresses generated during the casting and forging processes of steel pipes, and to prevent deformation and cracking, steel pipes need to be annealed. After annealing, the steel pipes are sorted and transported according to production needs. Existing steel pipe conveying devices usually move the pipes to the conveying device through a sorting device. However, when moving steel pipes to the conveying device, the general sorting device often moves two or more steel pipes at a time, requiring manual sorting, which increases the workload of the staff.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a steel pipe sorting and conveying device, which has the following features:

[0014] Beneficial effects:

[0015] 1. This steel pipe sorting and conveying device uses a feeding hopper, sliding rod, limit tube, hydraulic cylinder and measuring ruler in combination. This allows the operator to set the height of the limit tube according to the diameter of the steel pipe, so that the distance between the limit tube and the feeding hopper is just enough to accommodate one set of steel pipes. This ensures that the device can only accommodate one set of steel pipes at a time, avoiding the situation of feeding multiple sets of steel pipes to the conveying mechanism at one time, and improving the sorting quality of steel pipes.

The cam can drive the lifting plate to rise and fall through the pulley. When the feeding block is at a high point, the feeding block blocks the steel pipe in the feeding hopper. When the feeding block is at a low point, the steel pipe is released and falls into the conveying mechanism. This allows the device to convey the steel pipe to the conveying mechanism at a uniform speed, improving the continuity of the device's operation. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a steel pipe sorting and conveying device, including a base 1 and a conveying mechanism 2 fixed to the left side of the upper surface of the base 1. Four sets of support columns 3 are fixedly connected to the right side of the upper surface of the base 1. A feeding hopper 4 is fixedly connected to the upper surface of the support columns 3. A right support 5 is fixedly connected to the upper surface of the feeding hopper 4. A left support 6 is fixedly connected to the left side of the conveying mechanism 2. A limit device 7 is fixedly connected between the left support 6 and the right support 5. A discharge device 8 is provided on the right side of the outer surface of the conveying mechanism 2. Through the cooperation of the feeding hopper 4, sliding rod 702, limit tube 704, hydraulic cylinder 705 and measuring ruler 707, the operator can set the height of the limit tube 704 according to the diameter of the steel pipe, so that the limit tube 704 and the feeding hopper 704 are aligned. The distance between the hoppers 4 is just enough to allow one set of steel pipes to pass through, thus enabling the device to accommodate only one set of steel pipes at a time. This avoids the situation of feeding multiple sets of steel pipes to the conveying mechanism 2 at once, improving the sorting quality of the steel pipes. Through the coordinated use of the rotating shaft 801, stepper motor 802, feeding block 803, lifting rod 804, and cam 807, the cam 807 can drive the lifting plate 806 to rise and fall via the pulley 808. When the feeding block 803 is at a high point, it blocks the steel pipes in the feeding hopper 4. When the feeding block 803 is at a low point, the steel pipes are released and fall into the conveying mechanism 2. This allows the device to uniformly transport the steel pipes to the conveying mechanism, improving the continuity of the device's operation.

[0025] In this invention, to further improve the conveying performance of the steel pipe, the conveying mechanism 2 includes a trough frame 201. Multiple sets of conveying rollers 202 are rotatably connected to the inner wall of the trough frame 201. Each set of conveying rollers 202 is connected to each other by a transmission belt set 203. A motor frame 204 is fixedly connected to the front side of the right side of the trough frame 201. A drive motor 205 is fixedly connected to the inner wall of the motor frame 204. The output end of the drive motor 205 is fixedly connected to the right end of the conveying roller 202 located on the front side, so that the drive motor 205 drives the conveying roller 202 to rotate, and the conveying roller 202 drives the steel pipe to move, thereby further improving the conveying performance of the steel pipe.

[0026] In this invention, to ensure that the device releases only one set of steel pipes at a time, the limiting device 7 includes a fixed plate 701. The fixed plate 701 is fixedly connected to the left support 6 and the right support 5. A sliding rod 702 is slidably inserted into the front and rear sides of the upper surface of the fixed plate 701. A top plate 703 is fixedly connected to the top of the sliding rod 702, and a limiting tube 704 is fixedly connected to the bottom. A hydraulic cylinder 705 is fixedly connected between the fixed plate 701 and the top plate 703. A ruler sleeve 706 is fixedly connected to the front of the fixed plate 701. A measuring ruler 707 is slidably inserted into the inner wall of the ruler sleeve 706. The lower surface of the measuring ruler 707 is fixedly connected to the upper surface of the limiting tube 704, so that the limiting tube 704 plays a limiting role on the steel pipes, ensuring that the device releases only one set of steel pipes at a time.

[0027] In this invention, to ensure uniform release of the steel pipe, the feeding device 8 includes a rotating shaft 801 rotatably connected to the trough frame 201. A stepper motor 802 is fixedly connected to the middle of the bottom inner wall of the trough frame 201. The output end of the stepper motor 802 is fixedly connected to the left end of the rotating shaft 801. A feeding block 803 is slidably inserted into the middle of the left side of the lower surface of the feeding hopper 4. Two sets of lifting rods 804 are fixedly connected to the lower surface of the feeding block 803. A stabilizing plate 805 is slidably fitted onto the outer surface of the lifting rods 804. The left side of the stabilizing plate 805 is connected to the trough frame 201. The right side of the frame 201 is fixedly connected to the lifting rod 804 and the bottom end of the lifting plate 806 is fixedly connected to it. The right side of the outer surface of the rotating shaft 801 is fixedly fitted with a cam 807. The lower surface of the lifting plate 806 is fixedly connected to a pulley 808 that matches the cam 807, so that the cam 807 drives the lifting plate 806 to perform reciprocating lifting motion through the pulley 808. When the feeding block 803 is at a high point, the feeding block 803 blocks the steel pipe in the feeding hopper 4. When the feeding block 803 is at a low point, the steel pipe is released, so that the steel pipe is released at a uniform speed.

[0028] In this invention, in order to further enhance the rotational stability of the cam 807, a connecting key is connected to the outer surface of the rotating shaft 801, and a keyway adapted to the connecting key is provided on the inner wall of the cam 807. The stability of the cam 807 rotation is further enhanced by the cooperation between the connecting key and the keyway.

[0029] In this invention, in order to further enhance the stability of the sliding rod 702, two sets of stabilizing collars are slidably fitted on the outer surface of the sliding rod 702. The inner side of the stabilizing collar is fixedly connected to the outer surface of the fixing plate 701, so that the stabilizing collar plays a role in stabilizing the movement trajectory of the sliding rod 702, thereby further enhancing the stability of the sliding rod 702.

[0030] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0031] In operation, the hydraulic cylinder 705 is activated. The output end of the hydraulic cylinder 705 drives the top plate 703 to rise and fall. The top plate 703 drives the sliding rod 702 and the limiting tube 704 to rise and fall. The height of the limiting tube 704 is set according to the diameter of the steel pipe, and the reading is taken by the measuring ruler 707. The distance between the limiting tube 704 and the feeding hopper 4 is just enough to accommodate a set of steel pipes. The steel pipes are stacked on the feeding hopper 4. Under the action of gravity, the steel pipes are stacked to the left. The stepper motor 802 is activated, and the speed of the stepper motor 802 is set. The stepper motor 802 drives the rotating shaft 8 When cam 807 rotates, cam 807 drives lifting plate 806 to reciprocate through pulley 808. When feeding block 803 is at a high point, feeding block 803 blocks the steel pipe in feeding hopper 4. When feeding block 803 is at a low point, the steel pipe is released and falls into conveying mechanism 2. Drive motor 205 is started. Drive motor 205 drives conveying roller 202 located on the front side to rotate. Conveying roller 202 located on the front side drives the other conveying rollers 202 to rotate through transmission belt group 203. Conveying roller 202 conveys steel pipe.
