Description

Technical Field

[0001] This invention relates to the field of tubing storage technology, and in particular to a tubing coiling device. Background Technology

[0002] In hydropower station units, the handling of oil pipes is involved in the oil supply and drainage technology. The oil pipes are thickened steel wire pipes with quick-connect couplings, which are difficult to coil and prone to bending, requiring a large amount of labor during handling. In the past, the coiling process required the cooperation of multiple people, occupying a large work area, taking a long time, and potentially causing problems such as oil pipe breakage and residual oil contamination, thus affecting work efficiency and quality.

[0003] An existing patent (publication number: CN216889543U) discloses a structure including a base and a winding structure. The winding structure is located on top of the base, and the top of the base is equipped with a cable adjustment mechanism. The cable reel can be disassembled via a first support plate, a second support plate, a fixing plate, a first motor, a rotating rod, a cable reel, a placement slot, an electric push rod, and a connecting plate inside the winding structure, facilitating user replacement of the reel after winding. However, this technical solution still has shortcomings, specifically as follows:

[0004] The aforementioned device has guide wheels on its bottom surface. During the tubing winding process, the device vibrates, causing it to deflect or shift, making it difficult to wind the tubing stably. Therefore, we propose a tubing coiling device to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the invention, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Therefore, the purpose of this invention is to provide a tubing coiling device that can solve the problem that existing devices with guide wheels on the bottom surface vibrate during tubing coiling, causing the device to deflect or move during coiling, making it difficult for the device to coil the tubing stably.

[0007] To solve the above technical problems, the present invention provides an oil pipe coiling device, adopting the following technical solution: It includes a moving mechanism, which includes a tray. A through groove is formed on the lower side of the side of the tray. Two C-shaped abutment strips are movably inserted into the lower side of the inner wall of the through groove. The bottom ends of the two vertical rods of each C-shaped abutment strip are rotatably connected to a wheel. A hollow rectangular strip is fixedly connected to the opposite side of the two horizontal bars of the two C-shaped abutment strips. Two first tension springs are fixedly connected to the top surface of the hollow rectangular strip. The top ends of the first tension springs are fixedly connected to the top surface of the inner wall of the through groove. An L-shaped block is slidably connected to the side of the inner wall of the hollow rectangular strip. A first compression spring is fixedly connected to the rear side of the vertical block of the L-shaped block. The rear end of a compression spring is fixedly connected to the rear side of the inner wall of a through rectangular strip. A rectangular groove is opened on the bottom surface of the inner wall of the through groove. The horizontal block of the L-shaped block extends through the rectangular groove to the bottom surface of the tray and slides with the bottom surface of the tray. Two movable grooves are opened on the top surface of the middle part of the inner wall of the through groove. C-shaped grooves are opened on the upper sides of the front and rear sides of the tray. Two C-shaped plates are slidably connected to the side of the inner wall of the C-shaped groove. A rectangular frame is fixedly connected to the front and rear sides of the tray. A support strip is slidably connected to the side of the inner wall of the rectangular frame. A connecting block is fixedly connected to the left and right sides of the support strip. A second tension spring is fixedly connected to the top surface of the connecting block. The top end of the second tension spring is fixedly connected to the bottom surface of the rectangular frame.

[0008] The winding mechanism includes two V-shaped bars. The opposite sides of the two V-shaped bars are fixedly connected to the left and right sides of the tray, respectively. The top surfaces of the four diagonal bars of the two V-shaped bars are rotatably connected to a round rod. The left side of the left V-shaped bar is fixedly connected to two L-shaped bars. The top surfaces of the two vertical bars of the two L-shaped bars are fixedly connected to a motor. The right end of the rotating shaft of the motor is fixedly connected to the right end of the round rod. Protective rings are fixedly sleeved on both the left and right sides of the round rod. A cylinder is movably sleeved on the side of the round rod. Fixed frames are fixedly connected to the upper and lower sides of the left side of the cylinder.

[0009] By adopting the above technical solution, this solution provides ground support through support bars, ensuring the stability of the tubing coiling device for tubing winding, making tubing winding more convenient, and enabling compact winding of the tubing.

[0010] Optionally, there are two fixed frames. A T-shaped strip is movably inserted into the left side of each of the two fixed frames. The left end of the vertical strip of the T-shaped strip extends to the left side of the fixed frame and is fixedly connected to a C-shaped strip. A second compression spring is fixedly sleeved on the side of the vertical strip of the T-shaped strip. One end of the second compression spring is fixedly connected to the side of the inner wall of the fixed frame.

[0011] By adopting the above technical solution, this solution can clamp the side of the oil pipe using a T-shaped strip.

[0012] Optionally, there are two protective rings. Seven connecting rods are fixedly connected to the inner walls of both protective rings. The fourteen connecting rods are distributed in a ring with seven rods in a group, and are evenly spaced. One of the connecting rods in the group of seven has a groove on its side. A third compression spring is fixedly connected to the top surface of the inner wall of the groove. Pressure rods are slidably connected to the inner walls of the two grooves. The side of the pressure rod is fixedly connected to one end of the third compression spring.

[0013] By adopting the above technical solution, this solution can increase the overall toughness of the protective ring through the connecting rod, and ensure that the oil pipe will not loosen through the pressure rod.

[0014] Optionally, the bottom surface of the inner wall of the tray is provided with a 20° inclined groove, and the sides of the inner wall of the tray are rounded.

[0015] By adopting the above technical solution, this solution uses a sloping groove to facilitate the movement of residual oil inside the tray to one side of the inner wall of the tray.

[0016] Optionally, a wear-resistant ring is fixedly fitted onto the side of the wheel, and the wear-resistant ring is made of rubber.

[0017] By adopting the above technical solution, this solution increases the service life of the round wheel through the wear-resistant ring made of rubber.

[0018] Optionally, the vertical cross-section of the T-shaped strip is arc-shaped, and anti-slip grooves are provided on the side of the vertical strip of the T-shaped strip.

[0019] By adopting the above technical solution, this solution achieves a larger contact area between the vertical side of the arc-shaped T-shaped strip and the side of the oil pipe.

[0020] Optionally, an abutment block is fixedly connected to the top surface of the horizontal bar of the C-shaped abutment strip, and the cross-sectional shape of the abutment block is an isosceles trapezoid.

[0021] By adopting the above technical solution, this solution can drive the two C-shaped plates in front and behind to open to the front and back sides at the same time when the contact block with an isosceles trapezoidal cross section moves upward.

[0022] Optionally, the two vertical plates of the C-shaped plate are provided with a 30° bevel angle on their sides, the sides of the vertical plates of the C-shaped plate are slidably connected to the sides of the abutment block, the top surface of the support strip is provided with a 40° bevel angle, the top surface of the support strip is slidably connected to the sides of the horizontal plates of the C-shaped plate, and two 35° bevel angles are provided on opposite sides of the two horizontal plates of the two C-shaped plates.

[0023] By adopting the above technical solution, this solution can drive the two C-shaped plates to move forward and backward on both sides through the contact block, and drive the two support bars to move downward through the two C-shaped plates.

[0024] In summary, the present invention has at least one of the following beneficial effects: 1. Moving the L-shaped block backward causes the hollow rectangular strip to drive the two C-shaped contact strips, the wheel and the contact block to move upward, so that the contact block contacts the side of the vertical plate of the C-shaped plate, so that the two C-shaped plates open at the same time, and the side of the horizontal plate of the C-shaped plate contacts the top surface of the support strip, so that the support strip moves downward and supports the ground, ensuring the stability of the oil pipe coiling device for oil pipe winding and making oil pipe winding more convenient;

[0025] 2. The C-shaped strip pulls the two T-shaped strips to the left, compressing the two second compression springs c. One end of the oil pipe is inserted into the inside of the two fixed frames. The C-shaped strip, through the rebound force of the second compression spring c, moves the T-shaped strip to the right, clamping one end of the oil pipe. The motor drives the two protective rings, the round rod, and the cylinder to rotate, winding the oil pipe around the side of the cylinder. As the oil pipe winds, its side contacts the side of the pressure rod, allowing the side of the pressure rod to compress the side of the oil pipe, thus tightly winding the oil pipe.

[0033] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0034] Example 1, refer to Figure 1-4 In this embodiment, to address the problem that existing devices with guide wheels on the bottom surface vibrate during tubing winding, causing deflection and movement, and making stable tubing winding difficult, this invention discloses a tubing coiling device.

[0035] The system includes a moving mechanism 100, which comprises a tray 101. A 20° inclined groove is formed on the bottom surface of the inner wall of the tray 101. The sides of the inner wall of the tray 101 are rounded. The inclined groove facilitates the movement of residual oil inside the tray 101 to one side of the inner wall. A through groove 102 is formed on the lower side of the side of the tray 101. Two C-shaped abutment strips 103 are movably inserted into the lower side of the inner wall of the through groove 102. Abutment blocks 103a are fixedly connected to the top surface of the horizontal bars of the C-shaped abutment strips 103. The cross-sectional shape of the abutment block 103a is an isosceles trapezoid. When the isosceles trapezoidal abutment block 103a moves upward, it can drive the two C-shaped plates 1012 to open simultaneously to the front and rear sides. Both vertical rods have rotatably connected wheels 104 at their bottom ends. Wear-resistant rings, made of rubber, are fixedly fitted to the sides of the wheels 104, increasing their lifespan. Two C-shaped abutment bars 103 have hollow rectangular bars 105 fixedly connected to opposite sides of their two horizontal bars. Two first tension springs 106 are fixedly connected to the top surface of the hollow rectangular bars 105, with the top ends of the first tension springs 106 fixedly connected to the top surface of the inner wall of the through groove 102. L-shaped blocks 107 are slidably connected to the side of the inner wall of the hollow rectangular bars 105. First compression springs 108 are fixedly connected to the rear side of the vertical blocks of the L-shaped blocks 107, with the rear ends of the first compression springs 108 fixedly connected to the rear side of the inner wall of the hollow rectangular bars 105. Next, a rectangular groove 109 is formed on the bottom surface of the inner wall of the through groove 102. The horizontal block of the L-shaped block 107 extends through the rectangular groove 109 to the bottom surface of the tray 101 and slides in connection with the bottom surface of the tray 101. Two movable grooves 1010 are formed on the top surface of the middle part of the inner wall of the through groove 102. C-shaped grooves 1011 are formed on the upper sides of the front and rear sides of the tray 101. Two C-shaped plates 1012 are slidably connected to the side of the inner wall of the C-shaped groove 1011. The two vertical plates of the C-shaped plate 1012 have a 30° bevel angle on their sides. The side of the vertical plate of the C-shaped plate 1012 is slidably connected to the side of the abutment block 103a. The top surface of the support bar 1014 has a 45° bevel angle. The top surface of the support bar 1014 is slidably connected to the C-shaped plate 1012. The horizontal plates of plate 1012 are slidably connected to each other. Two 35° beveled angles are opened on the opposite side of the two horizontal plates of the two C-shaped plates 1012. The abutment block 103a can drive the two C-shaped plates 1012 to move forward and backward to the sides. The two C-shaped plates 1012a can drive the two support bars 1014 to move downward. The front and rear sides of the tray 101 are fixedly connected to the rectangular frame 1013. The inner wall of the rectangular frame 1013 is slidably connected to the support bar 1014. The left and right sides of the support bar 1014 are fixedly connected to the connecting block 1015. The top surface of the connecting block 1015 is fixedly connected to the second tension spring 1016. The top of the second tension spring 1016 is fixedly connected to the bottom surface of the rectangular frame 1013.

[0036] The specific working principle is as follows: by moving the L-shaped block 107 backward, the horizontal block of the L-shaped block 107 is released from fixing the bottom surface of the tray 101, causing the through rectangular strip 105 to drive the two C-shaped abutment strips 103, the wheel 104 and the abutment block 103a to move upward, so that the side of the abutment block 103a contacts the side of the vertical plate of the two front and rear C-shaped plates 1012, so that the two C-shaped plates 1012 open to the front and rear sides at the same time. By the side of the horizontal plate of the moving C-shaped plate 1012 abutting the top surface of the support strip 1014, the two support strips 1014 with inclined top surfaces move downward, so that the support strip 1014 can support the ground, ensuring the stability of the oil pipe coiling device when winding the oil pipe, and thus making the winding of the oil pipe more convenient.

[0037] Example 2, refer to Figure 1-4 In this embodiment, to address the problem that existing oil pipes are relatively rigid, leading to loosening during coiling, based on the same concept as in Embodiment 1, the oil pipe coiling device further includes:

[0038] The winding mechanism 200 includes two V-shaped bars 201. The opposite sides of the two V-shaped bars 201 are fixedly connected to the left and right sides of the tray 101, respectively. A round rod 202 is rotatably connected to the top surface of the four diagonal strips of the two V-shaped bars 201. Two L-shaped bars 203 are fixedly connected to the left side of the left V-shaped bar 201. A motor 206 is fixedly connected to the top surface of the two vertical strips of the two L-shaped bars 203. The right end of the rotating shaft of the motor 206 is fixedly connected to the right end of the round rod 202. Two protective rings 207 are fixedly fitted on both the left and right sides. Seven connecting rods 207a are fixedly connected to the inner walls of each of the two protective rings 207. These fourteen connecting rods 207a are arranged in a ring of seven at equal intervals on the inner walls of the two protective rings 207. One of the connecting rods 207a in each group of seven has a groove 207b on its side. A third compression spring 207c is fixedly connected to the top surface of the inner wall of the groove 207b. The inner walls of the two grooves 207b... A pressure rod 207d is slidably connected to the side. The side of the pressure rod 207d is fixedly connected to one end of the third compression spring 207c. The connecting rod 207a increases the overall toughness of the protective ring 207. The pressure rod 207d ensures that the oil pipe will not loosen. A cylinder 204 is movably sleeved on the side of the round rod 202. Fixing frames 205 are fixedly connected to the upper and lower sides of the left side of the cylinder 204. There are two fixing frames 205. The vertical cross-section of the T-shaped strip 205a is arc-shaped. The side of the vertical strip of the T-shaped strip 205a... The T-shaped bar 205a has anti-slip grooves, and the vertical side of the arc-shaped T-shaped bar 205a has a larger contact area with the side of the oil pipe. The T-shaped bar 205a is movably inserted into the left side of both fixed frames 205. The left end of the vertical bar of the T-shaped bar 205a extends to the left side of the fixed frame 205 and is fixedly connected to the C-shaped bar 205b. The side of the vertical bar of the T-shaped bar 205a is fixedly sleeved with the second compression spring 205c. One end of the second compression spring 205c is fixedly connected to the side of the inner wall of the fixed frame 205. The T-shaped bar 205a can clamp the side of the oil pipe.

[0039] The specific working principle is as follows: The C-shaped strip 205b drives the two T-shaped strips 205a to stretch to the left, compressing the two second compression springs 205c. One end of the oil pipe is inserted into the side of the inner wall of the two fixed frames 205. The C-shaped strip 205b is then released, and the rebound force generated when the C-shaped strip 205b returns to its original position by the two second compression springs 205c drives the two T-shaped strips 205a to move to the right, clamping one end of the oil pipe. The starting motor drives the two protective rings 207, the round rod 202, and the cylinder 204 to rotate, thereby winding the oil pipe around the side of the cylinder 204. When the oil pipe is wound, its side contacts the side of the pressure rod 207d, allowing the side of the pressure rod 207d to compress the side of the oil pipe, thus enabling the oil pipe to be tightly wound.

[0040] Example 3, refer to Figure 1-4 In this embodiment, in order to solve the problem that existing coiling devices are not convenient for retracting and extending their bottom casters, based on the same concept as in Embodiment 1 above, the oil pipe coiling device further includes:

[0041] The moving mechanism 100 includes a tray 101. A 20° inclined groove is formed on the bottom surface of the inner wall of the tray 101. The sides of the inner wall of the tray 101 are rounded. The inclined groove facilitates the movement of residual oil inside the tray 101 to one side of the inner wall. A through groove 102 is formed on the lower side of the side of the tray 101. Two C-shaped abutment strips 103 are movably inserted into the lower side of the inner wall of the through groove 102. Abutment blocks 103a are fixedly connected to the top surface of the horizontal bars of the C-shaped abutment strips 103. The cross-sectional shape of the abutment block 103a is an isosceles trapezoid. When the isosceles trapezoidal abutment block 103a moves upward, it can drive the two C-shaped plates 1012 to open simultaneously to the front and rear sides. Each vertical rod has a rotatable wheel 104 at its bottom. A wear-resistant ring is fixedly fitted to the side of each wheel 104. The wear-resistant ring is made of rubber, which increases the service life of the wheel 104. A through rectangular bar 105 is fixedly connected to the opposite side of the two horizontal bars of the two C-shaped contact strips 103. Two first tension springs 106 are fixedly connected to the top surface of the through rectangular bar 105. The top of each first tension spring 106 is fixedly connected to the top surface of the inner wall of the through groove 102. An L-shaped block 107 is slidably connected to the side of the inner wall of the through rectangular bar 105. A first compression spring 108 is fixedly connected to the rear side of the vertical block of the L-shaped block 107. The rear end of the first compression spring 108 is fixedly connected to the rear side of the inner wall of the through rectangular bar 105. A rectangular groove 109 is formed on the bottom surface of the inner wall of the through groove 102. The horizontal block of the L-shaped block 107 extends through the rectangular groove 109 to the bottom surface of the tray 101 and slides in connection with the bottom surface of the tray 101. Two movable grooves 1010 are formed on the top surface of the middle part of the inner wall of the through groove 102. C-shaped grooves 1011 are formed on the upper sides of the front and rear sides of the tray 101. Two C-shaped plates 1012 are slidably connected to the side of the inner wall of the C-shaped groove 1011. The sides of the two vertical plates of the C-shaped plate 1012 are each formed with a 30° bevel angle. The sides of the vertical plates of the C-shaped plate 1012 are slidably connected to the side of the abutment block 103a. The top surface of the support bar 1014 is formed with a 45° bevel angle. The top surface of the support bar 1014 is connected to the C-shaped plate. The horizontal plate of 1012 is slidably connected to the side. The two horizontal plates of the two C-shaped plates 1012 have two 35° beveled angles on opposite sides. The abutment block 103a can drive the two C-shaped plates 1012 to move forward and backward to the sides. The two C-shaped plates 1012a can drive the two support bars 1014 to move downward. The front and rear sides of the tray 101 are fixedly connected to the rectangular frame 1013. The inner wall of the rectangular frame 1013 is slidably connected to the support bar 1014. The left and right sides of the support bar 1014 are fixedly connected to the connecting block 1015. The top surface of the connecting block 1015 is fixedly connected to the second tension spring 1016. The top of the second tension spring 1016 is fixedly connected to the bottom surface of the rectangular frame 1013.

[0042] The specific working principle is as follows: by moving the horizontal block of the L-shaped block 107 to the bottom surface of the tray 101, the L-shaped block 107 drives the hollow rectangular strip 105 to contact the bottom surface of the inner wall of the through groove 102. The hollow rectangular strip 105 drives the two C-shaped abutment strips 103 to move downward, and the vertical strip of the C-shaped abutment strip 103 drives the wheel 104 on its bottom surface to move downward to the bottom surface of the support strip 1014. This allows the wheel 104 to be extended and retracted, thereby facilitating the movement of the entire coil device.

[0043] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
