Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe sleeve processing equipment, specifically to a steel pipe conveying device for sleeve-insulating pipes. Background Technology

[0002] In modern construction and industrial fields, polyethylene-coated steel pipes are favored due to their excellent performance and diverse applications. Polyethylene-coated steel pipes are composite insulated pipes, mainly composed of an inner steel pipe and a polyethylene outer sheath. The inner steel pipe carries the transporting medium, while the polyethylene outer sheath provides additional protection and insulation, preventing corrosion and damage from the external environment. This type of pipe can be used in the petrochemical industry, where its corrosion resistance effectively ensures the safety and stability of the transportation process. It can also be used in building engineering for water supply, drainage, and fire protection systems.

[0003] The processing of insulated pipes requires a sleeve-insertion operation on the steel pipes. A sleeve-insertion machine is used to insert a polyethylene outer protective sleeve onto the outer layer of the steel pipe. The steel pipe needs to be transported to the sleeve-insertion platform by a conveyor for the subsequent sleeve-insertion operation. The conveyor currently used consists of an inclined conveyor structure. The steel pipe is placed at the higher end, and due to the inclined plane, the steel pipe will automatically roll and move towards the lower end to complete the feeding.

[0004] However, when the steel pipe rolls freely on the inclined plane, its gravitational potential energy is converted into kinetic energy. Due to the excessively long rolling path, the steel pipe will collide with the feeding baffle set in front of the sleeve-making platform at high speed, which can easily lead to equipment damage. Furthermore, the small deviations accumulated over a long rolling distance will make the steel pipe deviate more severely, causing the steel pipe axis to deviate from the axis of the sleeve-making platform, thus affecting the sleeve-making accuracy. Utility Model Content

[0005] In view of this, the problem to be solved by this utility model is to provide a steel pipe conveying device for inserting insulation pipes.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A steel pipe conveying device for inserting insulation pipes includes an inclined conveying frame and a feeding baffle. The inclined conveying frame has an inclined structure, and the feeding baffle is provided at the lower end of the inclined conveying frame. The inclined conveyor is equipped with a path interval control component, which is used to control the segmented rolling of the steel pipe. The path interval control component includes a control part and a path interval part, and the control part is connected to each group of the path interval parts. Multiple sets of anti-reverse roll assemblies are arranged at intervals on the inclined conveyor frame. The anti-reverse roll assemblies are used to prevent the steel pipes from going backwards, and the installation position of each set of anti-reverse roll assemblies is located in front of each set of path intervals.

[0007] Furthermore, the path interval includes a rotating baffle and a buffer wheel. The rotating baffle is configured as a dovetail structure. The middle position of the rotating baffle is fixed on a first connecting shaft. The first connecting shaft is mounted on the inclined conveyor frame via bearings. The buffer wheel is rotatably installed at the upper tail end of the rotating baffle. The lower tail end of each rotating baffle is connected to a connector in the control unit via a second connecting shaft. The upper tail end of the rotating baffle is higher than the conveying surface of the inclined conveyor frame.

[0008] The upper end of the rotating baffle will block the rolling of the steel pipe. By arranging multiple sets of rotating baffles at intervals, the steel pipe can be rolled at intervals to complete the feeding.

[0009] Furthermore, the control unit also includes an interval control cylinder, which is mounted on a hinge seat via a third connecting shaft. The hinge seat is fixed to the high end of the inclined conveyor frame. The telescopic end of the interval control cylinder is hinged to an adjacent connecting member, and the adjacent connecting members are connected by a connecting rod.

[0010] The rotation of the rotating baffle is controlled by the extension and retraction of the hydraulic cylinder. In the initial state, the upper end of the rotating baffle is higher than the conveying surface of the inclined conveyor frame. After rotation, it is flush with the conveying surface, allowing the steel pipe to roll into the next interval.

[0011] Furthermore, each set of the anti-reverse roll assembly is installed on an auxiliary support frame, which is fixedly set between two sets of side plates on the inclined conveyor frame, and the top surface of the auxiliary support frame is flush with the conveying surface of the inclined conveyor frame.

[0012] An auxiliary support frame is fixedly installed in the middle of the two sets of side plates of the inclined conveyor frame to facilitate the local processing and installation of each part during the production of the device.

[0013] Furthermore, the anti-rollover assembly includes a rotating frame and a stop block. The two ends of the rotating frame are rotatably connected to the auxiliary support frame via connecting shafts, and the upper end of the rotating frame is higher than the top surface of the auxiliary support frame. The stop block is located on the rear side of the lower end of the rotating frame and is close to the rotating frame.

[0014] The rotating frame is restricted to rotating only in the direction of the steel pipe's rolling by using a stop block, thus preventing the steel pipe from rolling backwards.

[0015] Furthermore, the rotating frame also includes rollers and a gravity block. The upper end of the rotating frame is equipped with rollers, and the lower end is fixedly equipped with a gravity block.

[0016] The rollers are used to reduce the friction of the steel pipes as they pass through the rotating frame, and the gravity blocks are used to automatically reset the rotating frame after it rotates, so that the rotating frame remains vertical under normal conditions.

[0017] Furthermore, the feeding baffle is hinged to the telescopic end of the feeding cylinder, the feeding cylinder is hinged to the inclined conveyor frame via a hinge, and one end of the feeding baffle is higher than the conveying surface of the inclined conveyor frame. The feeding baffle is rotatably mounted on the inclined conveyor frame via a support shaft, and the feeding baffle is located between two sets of side plates of the inclined conveyor frame.

[0018] The loading baffle is a component used to connect the inclined conveyor frame with the sleeve-passing platform. After the steel pipe moves to the loading baffle, the loading baffle is rotated by the loading cylinder to make the loading baffle flush with the inclined conveyor frame, and the steel pipe is transported to the sleeve-passing platform to complete the loading operation.

[0019] The advantages and positive effects of this utility model are: (1) By designing a path interval control component, this utility model divides the original long conveying path into several short paths, thereby reducing the kinetic energy accumulated by the steel pipe in each path and controlling the rolling speed to reduce it, thus completely solving the problem of high-speed impact on the feeding baffle after the steel pipe accelerates over a long distance, and reducing equipment damage.

[0020] (2) After the path interval control component divides the path into several segments, the rolling distance of the steel pipe is shortened, thereby reducing the accumulation space of rolling deviation. In addition, whenever the steel pipe comes into contact with the rotating baffle, the guiding force generated by the contact can also correct the movement trajectory of the steel pipe, greatly reducing the situation of misalignment caused by deviation, and thus improving the success rate of sleeve insertion.

[0021] (3) The rotating baffle of the path interval control component can be started and stopped synchronously through the control unit. Only one steel pipe is allowed to pass through each path segment, so that the steel pipe rolls to the sleeve platform in sequence at fixed intervals, avoiding the problem of multiple pipes rolling chaotically.

[0022] (4) This utility model uses an anti-reverse rolling component to block the steel pipe from going backwards by rotating the frame, allowing the steel pipe to roll only in the downhill direction. It can also form a collaborative mechanism of segmented interception and one-way release in conjunction with the path interval control component, which can better avoid the situation of mutual interference between steel pipes after the path is segmented.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figures 1 to 5 As shown, this utility model provides a steel pipe conveying device for inserting insulation pipes, including an inclined conveyor frame 1 and a feeding baffle 2. The inclined conveyor frame 1 has an inclined structure, and the feeding baffle 2 is provided at the lower end of the inclined conveyor frame 1. With the help of the inclined conveying surface of the inclined conveyor frame 1, the steel pipe 100 is automatically rolled to the inserting table to complete the feeding. The inclined conveyor 1 is equipped with a path interval control component 3. The path interval control component 3 is used to control the steel pipe 100 to roll in an intermittent manner. The path interval control component includes a control part 31 and a path interval part 32. The control part 31 is connected to each group of path interval parts 32. Multiple sets of anti-reverse roll components 4 are installed at intervals on the inclined conveyor frame 1. The anti-reverse roll components 4 are used to prevent the steel pipe 100 from going in the opposite direction, and the installation position of each set of anti-reverse roll components 4 is located in front of each set of path intervals 32.

[0028] Specifically, such as Figure 2 As shown, the path spacing section 32 includes a rotating baffle 321 and a buffer wheel 322. The rotating baffle 321 is configured with a dovetail shape. The middle position of the rotating baffle 321 is fixed on a first connecting shaft 323. The first connecting shaft 323 is mounted on the inclined conveyor frame 1 via bearings. The buffer wheel 322 is rotatably mounted at the upper tail end of the rotating baffle 321. The lower tail end of each rotating baffle 321 is connected to the connector 312 in the control section 31 via a second connecting shaft 324, and the upper tail end of the rotating baffle 321 is higher than the conveying surface of the inclined conveyor frame 1. The connector 312 is a hollow block structure, and the lower tail end of the rotating baffle 321 is connected to the hollow groove of the connector 312 via the second connecting shaft 324.

[0029] The upper end of the inclined conveyor frame 1, which is higher than the conveying surface, will block the rolling of the steel pipe 100. Therefore, by setting multiple sets of rotating baffles 321 at intervals, the long conveying path is divided into several short paths, so that the steel pipe 100 rolls in segments to complete the feeding and transportation.

[0030] The control unit 31 also includes an interval control cylinder 311. The interval control cylinder 311 is mounted on a hinge seat 314 via a third connecting shaft 313. The hinge seat 314 is fixed to the high end of the inclined conveyor frame 1. The telescopic end of the interval control cylinder 311 is hinged to an adjacent connecting member 312. Adjacent connecting members 312 are connected by a connecting rod 315. The interval control cylinder 311 controls the rotation of the rotating baffle 321 through its telescopic movement. The upper end of the rotating baffle 321 is initially higher than the conveying surface of the inclined conveyor frame 1, and rotates to a position flush with the conveying surface, causing the steel pipe 100 in this interval to roll into the next interval. The connecting rod 315 enables unified control of multiple sets of rotating baffles 321, allowing them to operate synchronously.

[0031] like Figure 3 and Figure 4 As shown, each set of anti-reverse roll assembly 4 is installed on the auxiliary support frame 11. The auxiliary support frame 11 is fixedly set between the two sets of side plates 10 on the inclined conveyor frame 1, and the top surface of the auxiliary support frame 11 is flush with the conveying surface of the inclined conveyor frame 1. Therefore, both can play the role of supporting and conveying the steel pipe 100. This design is also to facilitate modular installation during the production of the device. For example, the anti-reverse roll assembly 4 can be installed on the auxiliary support frame 11 first, and then the assembled module can be fixedly installed on the inclined conveyor frame 1.

[0032] The anti-reverse roll assembly 4 includes a rotating frame 41 and a stop block 42. Both ends of the rotating frame 41 are rotatably connected to the auxiliary support frame 11 via connecting shafts. The upper end of the rotating frame 41 is higher than the top surface of the auxiliary support frame 11. The stop block 42 is located on the rear side of the lower end of the rotating frame 41 and is close to the rotating frame 41. The stop block 42 restricts the rotating frame 41 to rotate only in the rolling direction of the steel pipe 100, thus preventing the steel pipe 100 from rolling backwards. The rotating frame 41 also includes a roller 43 and a gravity block 4. 4. The upper end of the rotating frame 41 is equipped with rollers 43, and the lower end is fixedly equipped with a gravity block 44. The rollers 43 are used to reduce the friction of the steel pipe 100 as it passes through the rotating frame 41. The arc-shaped contact surface of the rollers 43 can be adapted to the outer circle of the steel pipe 100 to disperse the contact pressure and reduce the risk of physical damage such as pits and deformation on the surface of the steel pipe 100. The gravity block 44 is set to automatically reset the rotating frame 41 after it rotates due to gravity, so that the rotating frame 41 remains vertical under normal conditions.

[0033] like Figure 5 As shown, the feeding baffle 2 is hinged to the telescopic end of the feeding cylinder 21. The feeding cylinder 21 is hinged to the inclined conveyor frame 1 via a hinge. The hinge used is a conventional component that can be purchased, so its specific structure will not be described in detail.

[0034] The feeding baffle 2 is rotatably mounted on the inclined conveyor frame 1 via the support shaft 22, and the feeding baffle 2 is located between the two sets of side plates 10 of the inclined conveyor frame 1. The feeding baffle 2 is a component used to connect the inclined conveyor frame 1 with the sleeve-feeding platform. The steel pipe 100 moves to the feeding baffle 2 and stops moving. It is started by the feeding cylinder 21. The feeding cylinder 21 is hinged to the feeding baffle 2 and is hinged to the inclined conveyor frame 1, so as to control the feeding baffle 2 to rotate in the direction of the rolling of the steel pipe 100. When it rotates to be flush with the inclined conveyor frame 1, the steel pipe 100 continues to roll to the sleeve-feeding platform to complete the feeding operation.

[0035] The working principle and process of this utility model are as follows: like Figure 6As shown, this diagram illustrates the state of multiple steel pipes 100 during transportation, paused within each interval. The steel pipe 100 contacts the buffer wheel 322 at the upper end of each set of rotating baffles 321, preventing the steel pipe 100 from rolling. The buffer wheel 322 is designed so that its arc-shaped contact surface can be adapted to the outer circle of the steel pipe 100, dispersing the contact pressure and reducing the risk of physical damage such as dents and deformation on the surface of the steel pipe 100. Furthermore, if the steel pipe 100 deviates slightly during operation, the guiding force generated after the steel pipe 100 contacts the buffer wheel 322 can be used to correct the movement trajectory of the steel pipe 100, thereby reducing the situation of misalignment caused by deviation and improving the success rate of insertion. The interval control cylinder 311 in the path interval control component 3 is activated, and its telescopic end drives the connecting piece 312 to move backward. Simultaneously, the connecting rod 315 controls the other connecting pieces 312 to move synchronously, so that the rotating baffle 321 rotatably connected to each connecting piece 312 rotates at the same time, rotating to a position flush with the conveying surface of the inclined conveyor frame 1. This causes the steel pipe 100 in the previous interval to roll into the next interval, so that the steel pipe 100 rolls toward the sleeve table at fixed intervals, avoiding the problem of chaotic rolling of multiple pipes. In addition, the path interval control component 3 divides the original long conveying path into several short paths, so that the kinetic energy accumulated by the steel pipe 100 in each path is reduced, and the rolling speed is also controlled and reduced. This solves the problem of high-speed impact on the feeding baffle after the steel pipe 100 accelerates over a long distance, reducing equipment damage.

[0036] This utility model designs an anti-reverse rolling component 4. When the steel pipe 100 rolls toward the through-platform, when the roller 43 on the rotating frame 41 contacts the steel pipe 100, the rotating frame rotates due to the force of the steel pipe 100, thus allowing the steel pipe 100 to roll downhill. However, the design of the stop block 42 prevents the rotating frame 41 from rotating in the opposite direction, thus preventing the steel pipe 100 from running in reverse and colliding with other steel pipes 100. Furthermore, in conjunction with the path interval control component 3, it can form a segmented interception and one-way release coordination mechanism, better avoiding mutual interference between steel pipes 100 after the path is segmented.

[0037] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
