Description

Technical Field

[0001] This invention relates to the field of tube assemblies production equipment, specifically to a concentric assembly device and method for tube assemblies production. Background Technology

[0002] The busbar is a key conductive component in high-voltage power transmission and transformation systems. Its core structure consists of a coaxially nested inner conductor shield and an outer insulating shield. Currently, the concentric assembly of the inner conductor shield and the outer insulating shield relies mainly on manual operation. During operation, the inner conductor shield and the outer insulating shield must be placed on support frames, and they must be kept coaxial. Figure 1 As shown. The above operations generally have the following problems: Low assembly efficiency: During assembly, when the outer insulating screen passes the first support frame (point A) and the second support frame (point B), at least two workers must simultaneously lift the outer insulating screen and the inner conductor screen to avoid interference between the outer insulating screen and the support frame. Figures 2 to 3 As shown; High concentricity deviation: Repeated lifting operations are not only time-consuming and laborious, but also prone to concentricity deviation due to human error, which affects product quality. Summary of the Invention

[0003] The first technical problem to be solved by the present invention is to provide a material concentric assembly device for the production of tubes, which automatically adjusts the support posture through a self-rotating support device to avoid interference between the insulating outer screen and the support frame, thereby reducing manual intervention and improving assembly efficiency and concentricity.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A material concentric assembly device for tube production includes a horizontally arranged sliding guide device, at least two sets of self-reversing support devices vertically installed above the sliding guide device and sliding left and right along the sliding guide device, and at least two sets of ordinary support devices vertically installed above the sliding guide device and sliding left and right along the sliding guide device; wherein, a horizontally placed inner conductor screen is supported above the self-reversing support device and abuts against the sliding guide device, and a horizontally placed outer insulating screen is supported above the ordinary support device; Its core improvement lies in the following: The self-reversing support device includes a vertically arranged upright bracket, a sliding sleeve fixed horizontally to the bottom of the upright bracket, a reversing reference frame fixed vertically to the top of the upright bracket, a reversing seat rotatably mounted on the top of the reversing reference frame and capable of reversing left and right, a support roller rotatably mounted on the left and right ends of the reversing seat, a mounting base fixed horizontally to the bottom of the reversing reference frame, a left cylinder vertically fixed to the bottom of the mounting base and capable of abutting the left end of the reversing seat and flipping upwards, a right cylinder vertically fixed to the bottom of the mounting base and capable of abutting the right end of the reversing seat and flipping upwards, and an infrared ranging sensor installed in the center of the reversing seat facing upwards and electrically connected to both the left and right cylinders. By adopting the above solution, the self-rotating support device detects the position of the insulating outer screen through an infrared sensor and automatically rotates the support posture without manual lifting, which can shorten the assembly time of a single tube and thus improve assembly efficiency and concentricity; only one worker is needed to push the insulating outer screen to complete the assembly, reducing the number of collaborators by two.

[0005] In a preferred embodiment of a material concentric assembly device for tube production, in the initial state, the left cylinder and the right cylinder respectively abut against the flip seat, making the left end of the flip seat higher than the right end; when the infrared ranging sensor is triggered, the left cylinder and the right cylinder respectively abut against the flip seat, making the right end of the flip seat higher than the left end, thus avoiding interference between the insulating outer screen and the support roller.

[0006] As a preferred embodiment of a material concentric assembly device for tube production, the left cylinder has two locations, with the piston rods of the two cylinders respectively abutting the bottom of the left front end and the bottom of the left rear end of the flipping seat, further improving the stability of the support; the right cylinder has two locations, with the piston rods of the two right cylinders respectively abutting the bottom of the right front end and the bottom of the right rear end of the flipping seat, further improving the stability of the support.

[0007] As a preferred embodiment of a material concentric assembly device for tube production, the self-reversing support device further includes a side stop that is vertically fixed to the front and rear sides of the left end and the front and rear sides of the right end of the reversing seat; wherein the side stop is inclined and the angle between it and the horizontal plane is 45-60°, which can prevent the insulating outer screen from slipping off the self-reversing support device.

[0008] As a preferred embodiment of a material concentric assembly device for tube production, the sliding guide device includes a horizontally arranged base, a stop fixed vertically to the left end of the base, a slide rail (used in conjunction with slide sleeve one and slide sleeve two) horizontally fixed above the base and near the front and rear edges of the base, a reference base fixed vertically to the right side of the stop, and a reinforcing rib vertically connecting the base and the stop and near the front and rear edges of the base; wherein, the left end of the conductor inner screen is supported on the reference base and abuts against the stop; the self-rotating support device and the ordinary support device can slide freely along the sliding guide device, further improving the flexibility of assembling the conductor inner screen and the insulating outer screen.

[0009] As a preferred embodiment of a material concentric assembly device for tube production, the upper surface of the base has multiple anti-slip grooves that extend forward and backward and are linearly distributed left and right, increasing the friction between the worker and the ground, making it easier for the worker to push the insulating outer screen.

[0010] As a preferred embodiment of a material concentric assembly device for tube production, the ordinary support device includes a base frame, a sliding sleeve two fixed horizontally to the base frame, a column fixed vertically above the base frame, a lifting rod vertically installed inside the column and adjustable up and down along the column, a fixed reference frame vertically fixed to the top of the lifting rod, and a support roller two rotatably installed on the top of the fixed reference frame. The ordinary support device has the same structure as the existing support device and is only used for supporting the insulating outer screen, without a flipping function.

[0011] As a preferred embodiment of a material concentric assembly device for tube production, the ordinary support device further includes two side blocks that are vertically fixed to the front and rear sides of the top of the fixed reference frame; wherein, the two side blocks are inclined and the angle between them and the horizontal plane is 45-60°, which can prevent the insulating outer screen from slipping off the self-rotating support device.

[0012] The second technical problem to be solved by the present invention is to provide a method for concentric assembly of materials for tube assemblies. By further standardizing the operation method of the concentric assembly device for tube assemblies, a standardized method for concentric assembly of materials for tube assemblies is formed to improve work efficiency.

[0013] To achieve the above objectives, the present invention adopts the following technical solution: A method for concentric assembly of materials for tube assemblies, comprising assembling a conductor inner shield and an insulating outer shield using the aforementioned concentric assembly device for tube assemblies, wherein the operation steps are as follows: S1. Place the inner conductor screen horizontally above the self-flipping support device and make the left end of the inner conductor screen abut against the sliding guide device; S2. Place the insulating outer screen horizontally above the ordinary support device; S3. Adjust the initial state of the self-tilting support device so that the left cylinder and the right cylinder respectively abut against the tilting seat and the left end of the tilting seat is higher than the right end of the tilting seat. S4. The staff pushes the insulating outer screen to the left to assemble it with the conductor inner screen; S5. When the insulating outer screen is assembled to the location of the first self-rotating support device, the infrared ranging sensor will be triggered, thereby controlling the left cylinder and the right cylinder to abut against the rotating seat respectively and making the right end of the rotating seat higher than the left end of the rotating seat, so as to avoid interference between the insulating outer screen and the support roller. S6. When the outer insulating screen is assembled to the location of the second self-reversing support device, it is the same as step S5, and so on, until the outer insulating screen is completely assembled to the inner conductor screen. The order of S1 and S2 can be interchanged.

[0014] The beneficial effects of this invention are as follows: 1. Automated anti-interference: The self-reversing support device detects the position of the insulating outer screen through infrared sensors and automatically reverses the support posture without manual lifting, which can shorten the assembly time of a single tube and thus improve assembly efficiency and concentricity. 2. Reduced labor costs: Only one worker is needed to push the insulating outer screen to complete the assembly, reducing the number of collaborators by two; 3. Improve assembly accuracy: The reference seat and slide rail of the sliding guide device ensure the coaxiality of the conductor inner screen and the insulating outer screen, further improving the pass rate.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1, as Figure 4 As shown, a concentric assembly device for tube production includes a horizontally arranged sliding guide device 1, two sets of self-reversing support devices 2 vertically installed above the sliding guide device 1 and sliding left and right along the sliding guide device 1, and two sets of ordinary support devices 3 vertically installed above the sliding guide device 1 and sliding left and right along the sliding guide device 1; wherein, a horizontally placed inner conductor screen 4 is supported above the self-reversing support device 2 and abuts against the sliding guide device 1, and a horizontally placed outer insulating screen 5 is supported above the ordinary support devices 3.

[0020] like Figure 5 As shown, the sliding guide device 1 includes a horizontally arranged base 11, a stop 12 vertically welded and fixed to the left end of the base 11, a slide rail 13 horizontally welded and fixed above the base 11 and near the front and rear edges of the base 11 (used in conjunction with slide sleeve 1 22 and slide sleeve 2 32), a reference seat 14 vertically welded and fixed to the right side of the stop 12, and a reinforcing rib 15 vertically welded to the base 11 and the stop 12 and near the front and rear edges of the base 11; wherein, the left end of the conductor inner screen 4 is supported on the reference seat 14 and abuts against the stop 12; the self-rotating support device 2 and the ordinary support device 3 can slide freely along the sliding guide device 1, further improving the flexibility of the assembly of the conductor inner screen 4 and the insulating outer screen 5.

[0021] Continue as Figure 5 As shown, the upper surface of the base 11 has multiple anti-slip grooves 16 that extend forward and backward and are linearly distributed in the left and right array, which increases the friction between the worker and the ground and makes it easier for the worker to push the insulating outer screen 5.

[0022] like Figures 6 to 7 As shown, the self-flipping support device 2 includes a vertically arranged upright bracket 21, a sliding sleeve 22 horizontally welded and fixed to the bottom of the upright bracket 21, a flipping reference frame 23 vertically welded and fixed to the top of the upright bracket 21, a flipping seat 24 rotatably mounted on the top of the flipping reference frame 23 and capable of flipping left and right, a support roller 25 rotatably mounted on the left and right ends of the flipping seat 24, a mounting base 26 horizontally welded and fixed to the bottom of the flipping reference frame 23, a left cylinder 27 vertically welded and fixed to the bottom of the mounting base 26 and capable of abutting the left end of the flipping seat 24 and flipping upward, a right cylinder 28 vertically welded and fixed to the bottom of the mounting base 26 and capable of abutting the right end of the flipping seat 24 and flipping upward, and an infrared ranging sensor 29 installed in the center of the flipping seat 24 facing upward and electrically connected to both the left cylinder 27 and the right cylinder 28. Continue as Figures 6 to 7 As shown, there are two left cylinders 27, and the piston rods of the two cylinders abut against the bottom of the left front end and the bottom of the left rear end of the flipping seat 24, respectively, to further improve the stability of the support; there are two right cylinders 28, and the piston rods of the two right cylinders 28 abut against the bottom of the right front end and the bottom of the right rear end of the flipping seat 24, respectively, to further improve the stability of the support.

[0023] Continue as Figures 6 to 7 As shown, the self-rotating support device 2 also includes a side block 210 vertically welded and fixed to the front and rear sides of the left end and the front and rear sides of the right end of the rotating base 24; wherein, the side block 210 is inclined and the angle between it and the horizontal plane is 50°, which can be within the range of 45-60°, so as to prevent the insulating outer screen 5 from slipping off the self-rotating support device 2.

[0024] like Figure 8 As shown, the ordinary support device 3 includes a base frame 31, a sliding sleeve 32 horizontally welded and fixed to the base frame 31, a column 33 vertically welded and fixed above the base frame 31, a lifting rod 34 vertically installed inside the column 33 and adjustable up and down along the column 33, a fixed reference frame 35 vertically welded and fixed to the top of the lifting rod 34, and a support roller 36 rotatably installed on the top of the fixed reference frame 35. The ordinary support device 3 has the same structure as the existing support device and is only used for supporting the insulating outer screen 5, without a flipping function.

[0025] Continue as Figure 8 As shown, the ordinary support device 3 also includes a second side block 37 vertically welded and fixed to the front and rear sides of the top of the fixed reference frame 35; wherein, the second side block 37 is inclined and the angle between it and the horizontal plane is 50°, which can be within the range of 45-60°, so as to prevent the insulating outer screen 5 from slipping off the self-rotating support device 2.

[0026] like Figures 9 to 11As shown, in the initial state, the left cylinder 27 and the right cylinder 28 respectively abut against the flip seat 24, making the left end of the flip seat 24 higher than the right end of the flip seat 24; when the infrared ranging sensor 29 is triggered, the left cylinder 27 and the right cylinder 28 respectively abut against the flip seat 24, making the right end of the flip seat 24 higher than the left end of the flip seat 24, thus avoiding interference between the insulating outer screen 5 and the support roller 25.

[0027] Example 1, as Figures 9 to 11 As shown, a method for concentric assembly of materials for tube assembly is described. The method involves assembling the conductor inner shield 4 and the insulating outer shield 5 using the aforementioned concentric assembly device for tube assembly. The operation steps are as follows: S1. Place the inner conductor screen 4 horizontally above the self-rotating support device 2, ensuring the left end of the inner conductor screen 4 abuts against the sliding guide device 1. Figure 9 As shown; S2. Place the insulating outer screen 5 horizontally above the ordinary support device 3, such as... Figure 9 As shown; S3. Adjust the initial state of the self-rotating support device 2 so that the left cylinder 27 and the right cylinder 28 respectively abut against the rotating seat 24 and the left end of the rotating seat 24 is higher than the right end of the rotating seat 24. At this time, only the support rollers 25 on the left end of all the rotating seats 24 support the conductor inner screen 4. Figure 9 As shown; S4. The staff pushes the insulating outer screen 5 to the left to assemble it with the conductor inner screen 4, as follows: Figures 10 to 11 As shown; S5. When the insulating outer screen 5 is assembled to the location of the first self-rotating support device 2, the infrared ranging sensor 29 will be triggered, thereby controlling the left cylinder 27 and the right cylinder 28 to respectively abut against the rotating seat 24, making the right end of the rotating seat 24 higher than the left end. Since the insulating outer screen 5 has already passed the support roller 25 on the right end of the rotating seat 24, at this time, all the support rollers 25 on the right end of the rotating seats 24 support the insulating outer screen 5, avoiding interference between the insulating outer screen 5 and the support roller 25. Figure 10 As shown; S6. When the insulating outer screen 5 is assembled to the location of the second self-rotating support device 2, the process is the same as in step S5, such as... Figure 11 As shown, this process continues until the outer insulating screen 5 is fully assembled onto the inner conductor screen 4.

[0028] Example 2, as Figures 9 to 11 As shown, a method for concentric assembly of materials for tube production is described. The only difference between this embodiment and Embodiment 1 is that the order of steps S1 and S2 is interchanged.

[0029] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
