[0002] During the processing of the insulation pipe, the insulated steel pipe is usually sent to the pipe-laying platform where the protective pipe is placed using a double-chain pipe-threading machine and inserted into the protective pipe. The connected protective pipe and the insulation steel pipe are then lifted from the pipe-laying platform by a crane and placed on the hydraulic foaming platform for filling with insulation materials.

[0003] At present, in the process of processing insulated pipes, a double-chain pipe threading machine is generally used to transfer the insulated steel pipes to the pipe placing platform where the protective pipes are placed and insert them into the protective pipes. The pipes are then lifted and placed on the hydraulic foaming platform for filling with insulation materials. The double-chain pipe threading machine in the prior art has limited load capacity. Multiple insulated steel pipes are loaded on two chains, which puts great pressure on the chains, resulting in relatively low transmission efficiency and poor operating stability, affecting the working efficiency of the pipe threading machine. In addition, the chain transmission is not stable enough during the pipe threading process, accidents are prone to occur, and the equipment has a short service life. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 The utility model provides a new technical solution: a new double-chain pipe threading machine, including a base 1, two protective plates 2 are fixedly installed on the upper surface of the base 1, and slide grooves 9 are provided on the opposite surfaces of the two protective plates 2. The opposite surfaces of the two protective plates 2 are rotatably connected with a rotating shaft 3, and the left end of the rotating shaft 3 passes through the left surface of the protective plate 2. The left end of the rotating shaft 3 is fixedly connected with a motor 6, and the motor 6 is fixedly connected to the left surface of the protective plate 2. The protective plate 2 is provided with an auxiliary supporting device.

[0026] Furthermore, the auxiliary supporting device includes a sprocket 4, which is sleeved on the outer surface of the rotating shaft 3. The outer surface of the sprocket 4 is transmission-connected with a chain 5. A supporting plate 7 is fixedly installed on the upper surface of the chain 5. Six slots are provided on the upper surface of the supporting plate 7. Two fixing blocks 11 are fixedly installed on both sides of the six slots. Two spring slots 12 are provided on the opposite surfaces of the two fixing blocks 11. Springs 13 are fixedly installed on the inner walls of the two spring slots 12. Limiting blocks 14 are fixedly installed on the opposite surfaces of the springs 13. The upper and lower surfaces of the limiting blocks 14 are both inclined. Auxiliary wheels 8 are provided on both sides of the supporting plate 7. The auxiliary wheels 8 are slidably sleeved on the inner surface of the slide groove 9. When the novel double-chain pipe threading machine is used, the insulating pipe is placed in the six slots provided on the supporting plate 7. At this time, the insulating pipe hits the inclined surface of the limiting block 14, and applies pressure on the opposite side to the limiting block 14, so that the limiting block 14 moves toward the opposite side. The limiting block 14 The fixedly installed spring 13 applies pressure to cause it to contract. At this time, the limit block 14 contracts into the spring groove 12. After the insulation pipe is fully inserted, the limit block 14 is no longer under pressure, and the spring 13 is no longer under force. At this time, the spring 13 expands, and the spring 13 applies a thrust to the limit block 14, so that it is located above the insulation pipe to limit it. At this time, by starting the motor 6, the motor 6 outputs power to the rotating shaft 3 fixedly connected to the output end through operation. The rotating shaft 3 drives the sprocket 4 sleeved on the outer surface to rotate, and the sprocket 4 drives the chain 5 connected to the outer surface to rotate. The chain 5 drives the support plate 7 fixedly installed on the outer surface to move forward for pipe threading. The new double-chain pipe threading machine can effectively support the support plate through the auxiliary wheel, so that its surface can form an effective auxiliary support when it carries too much steel pipe. Without affecting the chain transmission, the pressure on the chain is reduced, the stability during operation is improved, and the service life of the equipment is extended.

[0027] Furthermore, the opposite surfaces of the two protective plates 2 are fixedly installed with a fixing plate 10, the inner surface of the fixing plate 10 is rotatably connected with a bidirectional threaded rod 15, the rear end of the bidirectional threaded rod 15 penetrates the rear surface of the fixing plate 10, the rear end of the bidirectional threaded rod 15 is fixedly connected with a knob 17, the outer surface of the bidirectional threaded rod 15 is threadedly sleeved with two clamping plates 16, and the opposite surfaces of the two clamping plates 16 are provided with brushes 18. The novel double-chain pipe threading machine can clean the surface of the chain 5 by the brush 18 when the chain is running, thereby increasing the service life of the chain. When the brush is replaced, the knob 17 can be turned, and the knob 17 drives the bidirectional threaded rod 15 fixedly connected at the front end to rotate. At this time, the two clamping plates 16 sleeved on the outer surface of the bidirectional threaded rod 15 continue to move toward the opposite side through the threads set on the outer surface of the bidirectional threaded rod 15. At this time, the brush 18 can be removed, and the installation of the brush can be completed by the opposite operation. The new double-chain pipe threading machine can clean the chain with the brush to prevent the chain from generating more dirt during operation and affecting the operation of the equipment. The brush can also be quickly replaced to clean the chain, which is more convenient.

[0028] Working principle: When the new double-chain pipe threading machine is used, the insulation pipe is placed in the six slots opened on the support plate 7. At this time, the insulation pipe hits the inclined surface of the limit block 14 and applies pressure on the opposite side to the limit block 14, so that the limit block 14 moves toward the opposite side. The limit block 14 applies pressure to the spring 13 fixedly installed on the opposite side to cause it to shrink. At this time, the limit block 14 shrinks into the spring groove 12. After the insulation pipe is fully inserted, the limit block 14 is no longer under pressure, and the spring 13 is no longer under force. At this time, the spring 13 expands, and the spring 13 applies a thrust to the limit block 14, so that it is located above the insulation pipe to limit it. At this time, the motor 6 is started, and the motor 6 outputs power to the output through operation. The rotating shaft 3 is fixedly connected to the end, and the rotating shaft 3 drives the sprocket 4 sleeved on the outer surface to rotate, and the sprocket 4 drives the chain 5 connected to the outer surface to rotate, and the chain 5 drives the supporting plate 7 fixedly installed on the outer surface to move forward to thread the pipe. The new double-chain pipe threading machine can clean the surface of the chain 5 through the brush 18 when the chain 5 is running, thereby increasing the service life of the chain. When the brush needs to be replaced, the knob 17 can be rotated, and the knob 17 drives the bidirectional threaded rod 15 fixedly connected to the front end to rotate. At this time, the two clamping plates 16 sleeved on the outer surface of the bidirectional threaded rod 15 continue to move toward the opposite side through the threads set on the outer surface of the bidirectional threaded rod 15. At this time, the brush 18 can be removed, and the installation of the brush can be completed by the opposite operation.
