Description

Technical Field

[0001] This utility model relates to the field of heating pipeline construction technology, and in particular to a docking device for heating pipeline construction. Background Technology

[0002] Heating pipelines are heat supply networks formed by the interconnection of multiple pipes. During installation, two heating pipelines need to be joined together to ensure their center points are at the same height for welding. Currently, the common practice for joining heating pipelines is for workers to use lifting equipment to lift and move the pipelines for the connection. This method is time-consuming, and aligning the center points requires slow movement of the lifting equipment to control the connection of the two pipelines. During this process, the pipelines may sway, affecting the efficiency of the connection. Utility Model Content

[0003] In order to overcome the shortcomings mentioned in the background art, the purpose of this utility model is to provide a docking device for heating pipeline construction.

[0004] Technical Solution: A docking device for heating pipeline construction includes a trolley, an mounting plate fixedly connected to the upper part of the trolley, a moving groove formed on the mounting plate, a bidirectional lead screw rotatably connected within the moving groove, nuts symmetrically distributed threaded onto the bidirectional lead screw, a first mounting frame mounted on the top of the nuts, a reduction motor connected to the end of the bidirectional lead screw and mounted on the side wall of the mounting plate, a first arc-shaped plate fixedly connected to the first mounting frame, first electric compression cylinders symmetrically distributed and fixedly connected to the first arc-shaped plate, first ball bearings rotatably connected to the end of the first electric compression cylinders, an infrared emitter fixedly connected to the side wall of the first mounting frame, and a lifting assembly for moving the pipeline to be docked to a suitable height on the other side of the trolley.

[0005] As an improvement to the above solution, the lifting assembly includes a scissor-type electric lifting frame installed on the other side of the trolley. A lifting plate is installed on the top of the scissor-type electric lifting frame. A symmetrically distributed guide block is fixed to the side wall of the lifting plate. A symmetrically distributed guide rod is fixed to the mounting plate, and the guide rod slides with the guide block. A symmetrically distributed sliding groove is opened on the lifting plate. A slider is slidably connected in the sliding groove. A second mounting frame is fixed to the top of the slider. An infrared receiver is provided on the side wall of the second mounting frame. The infrared receiver cooperates with the infrared transmitter. A second arc-shaped plate is fixed to the second mounting frame. A symmetrically distributed second electric compression cylinder is fixed to the second arc-shaped plate. A second ball bearing is rotatably connected to the end of the second electric compression cylinder. A moving part for synchronous movement of the first arc-shaped plate and the second arc-shaped plate is provided between the nut and the slider.

[0006] As an improvement to the above solution, the movable component includes a connecting frame fixed to the bottom of the nut, the connecting frame passing through the mounting plate and slidably connected thereto, and a movable rod passing through the lifting plate fixed to the bottom of the slider, the movable rod slidingly engaging with the lifting plate, and the end of the movable rod slidably connected within the connecting frame.

[0007] As an improvement to the above solution, a rack is fixedly connected to the bottom of the lifting plate, a fixing frame is fixedly connected to the bottom of the mounting plate, a transmission gear is connected to the lower part of the fixing frame via a shaft, the transmission gear meshes with the rack, a ratchet is fixedly connected to the end of the shaft, a pawl is connected to the side wall of the fixing frame via a rotating rod, the pawl engages with the ratchet, a torsion spring is sleeved on the rotating rod, one end of the torsion spring is connected to the fixing frame, and the other end of the torsion spring is fixedly connected to the pawl.

[0008] As an improvement to the above solution, a handle is fixedly connected to the pawl, a guide rod is fixedly connected to the handle, an installation rod is fixedly connected to the moving rod on one side, and a vertical plate is fixedly connected to the installation rod. The side wall of the vertical plate has a first track groove, a second track groove, and a third track groove. The guide rod is slidably connected in the third track groove. The third track groove is connected to the first track groove and the second track groove respectively. The first track groove is located below the second track groove. A baffle is fixedly connected to the third track groove through a connecting rod. A torsion spring is sleeved on the connecting plate. One end of the torsion spring is fixedly connected to the baffle, and the other end of the torsion spring is fixedly connected to the vertical plate.

[0009] This invention has the following advantages: Two first arc-shaped plates come together to form a ring that encloses one heating pipe, and two second arc-shaped plates come together to form a ring that encloses the other heating pipe. When the user activates the first and second electric compression cylinders, their operation moves the first and second ball bearings towards the center point of the heating pipe, thus clamping and fixing the pipe. The scissor-type electric lifting frame moves the lifting plate upwards, causing the upper heating pipe to move upwards. Through the cooperation of an infrared transmitter and receiver, the two supply pipes are made to have the same height and center point, facilitating the docking of the two heating pipes. This avoids the problem of the heating pipes swaying during docking, which would affect docking efficiency. The above operation avoids the problem of long docking times and reduced docking efficiency in the traditional heating pipe docking process. Attached Figure Description

[0017] Example 1

[0018] A docking device for heating pipeline construction, such as Figures 1-5 As shown, the device includes a trolley 1, with a mounting plate 2 fixedly attached to the upper part of the trolley 1. The mounting plate 2 has a moving groove, and a bidirectional lead screw 3 is rotatably connected in the moving groove. Two nuts 4 are threaded onto the bidirectional lead screw 3 and are symmetrically distributed front and back. A first mounting bracket 5 is mounted on the top of the nuts 4. A reduction motor 6 connected to the rear end of the bidirectional lead screw 3 is provided on the rear side wall of the mounting plate 2. A first arc-shaped plate 7 is fixedly attached to the first mounting bracket 5. Two first electric compression cylinders 8 are symmetrically distributed vertically on the first arc-shaped plate 7. A first ball bearing 9 is rotatably connected to the end of the first electric compression cylinder 8. An infrared emitter 10 is fixedly attached to the left side wall of the first mounting bracket 5. A lifting assembly for moving the pipe to be connected to a suitable height is provided on the left side of the top of the trolley 1.

[0019] The lifting assembly includes a scissor-type electric lifting frame 11 installed on the top left side of the trolley 1. A lifting plate 12 is installed on the top of the scissor-type electric lifting frame 11. Two guide blocks 13 are fixedly connected to the right side wall of the lifting plate 12 in a symmetrical arrangement. Two guide rods 14 are fixedly connected to the left side of the mounting plate 2 in a symmetrical arrangement, and the guide rods 14 are slidably engaged with the guide blocks 13. Two sliding grooves 15 are opened on the lifting plate 12 in a symmetrical arrangement. A slider 16 is slidably connected in the sliding grooves 15. A second mounting frame 17 is fixedly connected to the top of the slider 16. An infrared receiver 18 is provided on the right side wall of the second mounting frame 17. The infrared receiver 18 cooperates with the infrared transmitter 10. A second arc plate 19 is fixedly connected to the second mounting frame 17. Two second electric compression cylinders 20 are fixedly connected to the second arc plate 19 in a symmetrical arrangement. A second ball bearing 21 is rotatably connected to the end of the second electric compression cylinder 20. A moving part for synchronous movement of the first arc plate 7 and the second arc plate 19 is provided between the nut 4 and the slider 16.

[0020] The movable component includes a connecting frame 22 fixed to the bottom of the nut 4. The connecting frame 22 passes through the mounting plate 2 and is slidably connected to it. The bottom of the slider 16 is fixed with a moving rod 23 that passes through the lifting plate 12. The moving rod 23 is slidably engaged with the lifting plate 12, and the right end of the moving rod 23 is slidably connected to the connecting frame 22.

[0021] A rack 24 is fixedly connected to the bottom of the lifting plate 12, and a fixed frame 25 is fixedly connected to the bottom of the mounting plate 2. A transmission gear 26 is connected to the lower part of the fixed frame 25 through a shaft. The transmission gear 26 meshes with the rack 24. Both ends of the shaft on the fixed frame 25 are fixedly connected with ratchet 27. The front and rear side walls of the fixed frame 25 are connected with pawls 28 through rotating rods. The pawls 28 cooperate with the ratchet 27. A torsion spring is sleeved on the rotating rod on the fixed frame 25. One end of the torsion spring is connected to the fixed frame 25, and the other end of the torsion spring is fixedly connected to the pawl 28.

[0022] In use, the user moves the trolley 1 to the desired position and positions the two heating pipes between the two first arc-shaped plates 7 and the two second arc-shaped plates 19 respectively (the middle section of the heating pipe between the two second arc-shaped plates 10 is lifted by a hoisting device). Then, the reduction motor 6 is started, causing the double-acting screw 3 to rotate clockwise. This clockwise rotation of the double-acting screw 3 brings the two nuts 4 together. The movement of the nuts 4 moves the first mounting bracket 5 and the first arc-shaped plate 7 on them. After the two first arc-shaped plates 7 come together and contact, they form a ring that wraps around one of the heating pipes. During this process, the nuts... The movement of the connecting frame 22 causes the connecting frame 22 to move. The movement of the connecting frame 22 causes the slider 16 to move via the moving rod 23. The movement of the slider 16 causes the second arc plate 19 to move via the second mounting frame 17. After the two second arc plates 19 come together and contact each other, they form a ring that wraps around the other heating pipe. At this time, the user starts the first electric compression cylinder 8 and the second electric compression cylinder 20. The operation of the first electric compression cylinder 8 and the second electric compression cylinder 20 can move the first ball 9 and the second ball 21 on them to the center point of the heating pipe, thereby clamping and fixing the two heating pipes respectively through the first ball 9 and the second ball 21.

[0023] Then, the operator starts the scissor lift 11 to move the lifting plate 12 upwards (at this time, the lifting equipment will slowly move the heating pipe it is lifting upwards synchronously with the lifting plate 12 to avoid the heating pipe tilting and affecting the docking installation). The upward movement of the lifting plate 12 can move the heating pipe on its upper side upwards. At this time, the second mounting bracket 17 moves upwards, and the infrared transmitter 10 works to send a signal. During the upward movement of the second mounting bracket 17, it drives the infrared receiver 18 to move upwards. When the infrared receiver 18 moves upwards to the same height as the infrared transmitter 10, it can receive the signal sent by the infrared transmitter 10. The scissor lift 11 then stops working. At this time, the two supply pipes are at the same height and their center points are at the same height, thus enabling... To achieve the connection of two heating pipes, the process avoids the pipes swaying during the center-point connection, which could affect the connection efficiency. The operator then welds the pipes using welding equipment. After the two pipes are installed, the operator starts the reduction motor 6 to rotate the bidirectional lead screw 3 in the opposite direction, thus moving the two first arc plates 7 and two second arc plates 19 away from each other. During this process, the first and second electric compression cylinders 8 and 20 move the first ball bearing 9 and second ball bearing 21 back to their initial positions. Simultaneously, the operator uses the scissor-type electric lifting frame 11 to move the lifting plate 12 downwards to reset it. This operation avoids the problem of excessive time spent during the connection process, which could reduce the connection efficiency.

[0024] Example 2

[0025] Based on Example 1, such as Figures 3-5 As shown, a handle 29 is fixed between the front and rear pawls 28, and a guide rod 30 is fixed to the handle 29. An installation rod 31 is fixed to the right side wall of the front moving rod 23. A vertical plate 32 is fixed to the rear end of the installation rod 31. A first track groove 33, a second track groove 34, and a third track groove 35 are provided on the left side wall of the vertical plate 32. The guide rod 30 is slidably connected in the third track groove 35. The third track groove 35 is connected to the first track groove 33 and the second track groove 34 respectively, and the third track groove 35 is an inclined groove. The first track groove 33 is located below the second track groove 34. A baffle 36 is fixed in the third track groove 35 through a connecting rod. A torsion spring is sleeved on the connecting rod in the third track groove 35. One end of the torsion spring is fixed to the baffle 36, and the other end of the torsion spring is fixed to the vertical plate 32.

[0026] During the above process, when the lifting plate 12 moves upward, the transmission gear 26 can rotate through the rack 24. The pawl 28 and ratchet 27 work together to limit the rotation of the transmission gear 26 and prevent reverse rotation. This avoids the lifting plate 12 moving rapidly downward and causing the heating pipe to tilt, thus affecting installation, if the scissor-type electric lifting frame 11 is damaged. During this process, the two nuts 4 move closer together, causing the mounting rod 31 to move the vertical plate 32 via the connecting frame 22. The movement of the vertical plate 32 allows the guide rod 30 to enter the first track groove 33. During the process of the two first arc-shaped plates 7 contacting to form a ring, the guide rod 30 pushes the baffle 36 to swing upward, and the torsion spring tightens and stores force. When the two first arc-shaped plates 7 contact to form a ring, the guide rod 30 moves away from the baffle 36, and the baffle 36 swings back to its original position under the action of the torsion spring. When the four nuts move away from each other, the guide rod 30 is engaged with the third track groove 35 on the vertical plate 32, causing the guide rod 30 to move upward (because the third track groove is an inclined groove, the inclined surface of the third track groove can squeeze the guide rod to move upward during the vertical plate's resetting process). The upward movement of the guide rod 30 causes the pawl 28 to swing upward away from the ratchet 27 via the handle 29, releasing the limit on the transmission gear 26. The torsion spring then tightens and stores power. When the guide rod 30 enters the second track groove 34, the vertical plate 32 moves to maintain the height of the guide rod 30 after the movement, facilitating the movement of the heating pipe out between the two second arc plates 19. When the vertical plate 32 moves and the guide rod 30 moves out of the second track groove 34, the pawl 28 swings back to its reset position under the action of the torsion spring and engages with the ratchet 27. At this time, the lifting plate 12 moves downward to the initial position.
