Therefore, when the inclination angle of the pipeline needs to be adjusted, the worm only needs to be driven to rotate, and the transmission mode of the worm wheel and the worm has a self-locking function, so that the pipeline can be kept relatively stable when it is in an inclined state.

Description

Technical Field

[0001] This application belongs to the technical field of pipeline installation equipment, and more specifically, relates to a docking device for pipeline installation. Background Technology

[0002] Electromechanical piping refers to enclosed structures used for transporting fluids (water, gas, oil, etc.) or protecting electrical wires / busbars. In electromechanical installation, the installation of electromechanical piping is a crucial aspect. Large factory construction often requires the installation of numerous heavy pipes within the factory premises. Typically, two sets of pipes are connected using hoisting equipment, and once aligned, they are secured together with pipe clamps. Due to terrain and space constraints, pipes often need to be installed at an angle, necessitating adjustments to the inclination angle. However, hoisting equipment uses wire ropes to lift the pipes, and to ensure safety during hoisting, the pipes must remain horizontal, making it impossible to adjust the inclination angle. Utility Model Content

[0003] The purpose of this application is to provide a docking device for pipeline installation, which aims to solve the problem that existing hoisting equipment cannot adjust the tilt angle of electromechanical pipelines.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a pipe installation docking device is provided, comprising: a frame, a rotating shaft, a support beam, and a clamping member; the rotating shaft is rotatably mounted on the top of the frame in a horizontal direction, a worm gear is fixedly mounted on the rotating shaft, a worm gear meshing with the worm gear is correspondingly mounted on the frame, the support beam is fixedly mounted on the rotating shaft and remains perpendicular to the rotating shaft, and the clamping member is mounted on the support beam, the clamping member being used to clamp and fix the pipe; through the transmission mechanism of the worm gear and the worm gear, the support beam is driven to rotate around the rotating shaft, thereby changing the inclination angle of the pipe on the clamping member.

[0005] In one possible implementation, there are two clamping members, located on opposite sides of the rotation axis.

[0006] In one possible implementation, the top of the clamping member is provided with a slider, which slides in engagement with the support beam. The slider has a degree of freedom to move along the length direction of the support beam. A lead screw is mounted on the support beam, which is parallel to the length direction of the support beam. The top of the slider is connected to the lead screw by a thread.

[0007] In one possible implementation, the bottom of the clamping member is provided with a U-shaped frame for placing the pipe, the opening of the U-shaped frame facing downwards, and clamping rods and clamping blocks are respectively installed on the opposite inner sidewalls of the U-shaped frame. The clamping rods are slidably installed on the U-shaped frame in the horizontal direction, and a first limiting flange and a second limiting flange are respectively provided at both ends of the clamping rod in the length direction. The first limiting flange and the second limiting flange are located on the inner and outer sides of the U-shaped frame, respectively. An elastic element is installed on the clamping rod, and the elastic element applies a force to the clamping rod toward the clamping block. The clamping block is fixedly connected to the U-shaped frame. By applying a force to the clamping rod, the elastic element causes the first limiting flange and the clamping block to clamp and fix the pipe.

[0008] In one possible implementation, the elastic element is a compression spring, fitted onto the clamping rod; one end of the elastic element abuts against the first limiting flange, and the other end abuts against the inner wall of the U-shaped frame.

[0009] In one possible implementation, the side of the clamping block facing the clamping rod is an inclined surface, which slopes downwards towards the side closer to the clamping rod.

[0010] In one possible implementation, a safety chain is installed at the bottom opening of the U-shaped frame.

[0011] In one possible implementation, a protective cover is mounted on the frame to cover the worm gear and the worm.

[0012] In one possible implementation, the frame is equipped with wheels at its bottom.

[0013] In one possible implementation, a lifting ring is installed on the top surface of the frame.

[0014] Compared with the prior art, the pipe installation docking device of this application has a rotating shaft installed on the top of the frame. The axis of the rotating shaft is set horizontally, and a support beam is fixedly installed on the rotating shaft, and the support beam is perpendicular to the axis of the rotating shaft. Since the clamping member is fixedly installed on the support beam, when the rotating shaft rotates, it can drive the pipe on the clamping member to move synchronously, thereby changing the tilt angle of the pipe. A worm gear is fixedly installed on the rotating shaft, and a worm gear meshing with the worm gear is installed on the frame. Therefore, when it is necessary to adjust the tilt angle of the pipe, it is only necessary to drive the worm gear to rotate. Moreover, the transmission method of the worm gear and the worm gear has a self-locking function, thereby ensuring that the pipe remains relatively stable when it is tilted.

[0024] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0025] Please refer to the following: Figure 1 and Figure 2 This application describes a pipe installation docking device. The device includes: a frame 1, a rotating shaft 101, a support beam 102, and a clamping member 103. The rotating shaft 101 is rotatably mounted on the top of the frame 1 in a horizontal direction. A worm gear 104 is fixedly mounted on the rotating shaft 101. A worm 105, meshing with the worm gear 104, is correspondingly mounted on the frame 1. The support beam 102 is fixedly mounted on the rotating shaft 101 and perpendicular to it. The clamping member 103 is mounted on the support beam 102 and is used to clamp and fix the pipe 2. Through the transmission mechanism of the worm gear 104 and the worm 105, the support beam 102 is driven to rotate around the rotating shaft 101, thereby changing the inclination angle of the pipe 2 on the clamping member 103.

[0026] This embodiment provides a pipe installation docking device. Compared with the prior art, a rotating shaft 101 is installed on the top of the frame 1. The axis of the rotating shaft 101 is set in the horizontal direction. A support beam 102 is fixedly installed on the rotating shaft 101, and the support beam 102 is perpendicular to the axis of the rotating shaft 101. Since the clamping member 103 is fixedly installed on the support beam 102, when the rotating shaft 101 rotates, it can drive the pipe 2 on the clamping member 103 to move synchronously, thereby changing the tilt angle of the pipe 2. A worm gear 104 is fixedly installed on the rotating shaft 101, and a worm 105 that meshes with the worm gear 104 is installed on the frame 1. Therefore, when it is necessary to adjust the tilt angle of the pipe 2, it is only necessary to drive the worm 105 to rotate. Moreover, the transmission method of the worm gear 104 and the worm 105 has a self-locking function, thereby ensuring that the pipe 2 remains relatively stable when it is in a tilted state.

[0027] In this embodiment, support legs are installed at the four corners of the frame 1, and a rotating shaft 101 is installed on the top of the frame 1, with the rotating shaft 101 arranged along the width direction of the frame 1. The support beam 102 is initially kept in a horizontal state, and at this time, the support beam 102 is parallel to the length direction of the frame 1. The frame 1 is a frame structure, and a clearance space is provided in its central area to allow the support beam 102 to pass.

[0028] In some embodiments, please refer to Figure 1 and Figure 2There are two clamping members 103, located on both sides of the rotating shaft 101. In this embodiment, the two clamping members 103 simultaneously clamp and fix the pipe 2, thereby ensuring the force balance of the pipe 2. The support beam 102 is cylindrical. The diameter of the rotating shaft 101 is larger than the diameter of the support beam 102, so the rotating shaft 101 can withstand a larger load, thus ensuring that it can withstand the torque applied to the rotating shaft 101 by the pipe 2. The support beam 102 passes through the center of the rotating shaft 101 and is fixedly connected to the rotating shaft 101 by screws. In order to improve the connection strength between the support beam 102 and the rotating shaft 101, the connection between the support beam 102 and the rotating shaft 101 can also be circumferentially welded. The rotating shaft 101 is located at the center of the support beam 102, thereby ensuring that the entire frame 1 is under balanced force when the support beam 102 is in a horizontal state. Since the two clamping members 103 are located on both sides of the rotating shaft 101, the support beam 102 can avoid generating excessive torque on the rotating shaft 101 when subjected to the force of the pipe 2.

[0029] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 5The clamping member 103 has a slider 106 at its top, which slides in engagement with the support beam 102. The slider 106 has the freedom to move along the length of the support beam 102. A lead screw 107 is mounted on the support beam 102, parallel to its length. A connecting block 108, threadedly connected to the lead screw 107, is located at the top of the slider 106. In this embodiment, the slider 106 is located at the top of the clamping member 103. The bottom of the clamping member 103 is used to clamp and fix the pipe 2. The clamping member 103 is slidably mounted on the support beam 102 via the slider 106, allowing its position to be adjusted along the length of the support beam 102, thereby changing the distance between the two clamping members 103. This not only adapts to pipes 2 of different lengths but also effectively reduces the torque on the rotating shaft 101. The number of lead screws 107 can be one or two. When there is one lead screw 107, it is threadedly connected to the sliders 106 on both clamping members 103. However, the threads on the two sliders 106 turn in opposite directions, so rotating the lead screw 107 can simultaneously move the two clamping members 103 closer or further apart. When there are two lead screws 107, the lead screw and slider 106 correspond one-to-one, meaning each lead screw 107 drives its corresponding slider 106 independently. Therefore, the distances between the two sliders 106 and the rotating shaft 101 can be the same or different. A handle is installed at one end of the lead screw 107 for easy gripping by the operator. The operator needs to manually drive the lead screw 107 to rotate using the handle, thereby moving the slider 106 along the length of the support beam 102.

[0030] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5The bottom of the clamping member 103 is provided with a U-shaped frame 109 for placing the pipe 2. The opening of the U-shaped frame 109 faces downward. A clamping rod 110 and a clamping block 111 are respectively installed on the opposite inner sidewalls of the U-shaped frame 109. The clamping rod 110 is slidably installed on the U-shaped frame 109 in the horizontal direction. A first limiting flange 112 and a second limiting flange 113 are respectively provided at both ends of the clamping rod 110 in the length direction. The first limiting flange 112 and the second limiting flange 113 are located on the inner and outer sides of the U-shaped frame 109, respectively. An elastic element 114 is installed on the clamping rod 110. The elastic element 114 applies a force to the clamping rod 110 toward the clamping block 111. The clamping block 111 is fixedly connected to the U-shaped frame 109. By applying a force to the clamping rod 110, the elastic element 114 clamps and fixes the pipe 2 with the first limiting flange 112 and the clamping block 111. In this embodiment, the clamping member 103 includes a slider 106, a connecting rod 122, and a U-shaped frame 109 connected sequentially from top to bottom. Adjacent parts are fixed by welding. The opening of the U-shaped frame 109 faces downward, facilitating the entry of the pipe 2 into the U-shaped frame 109 from below. The through groove of the U-shaped frame 109 faces the length direction of the support beam 102, so the pipe 2 remains parallel to the length direction of the support beam 102 when inside the U-shaped frame 109. The clamping rod 110 and the clamping block 111 are respectively installed on opposite side walls of the inner cavity of the U-shaped frame 109. The clamping rod 110 is slidably installed on the U-shaped frame 109 in the horizontal direction, and the clamping rod 110 can move towards or away from the clamping block 111. The clamping rod 110 is a cylindrical rod. The first limiting flange 112 and the second limiting flange 113 are both disc-shaped with a diameter larger than that of the clamping rod 110, effectively preventing the clamping rod 110 from detaching from the U-shaped frame 109. The first limiting flange 112 and the second limiting flange 113 are located on the inner and outer sides of the U-shaped frame 109, respectively. When clamping and fixing the pipe 2, the first limiting flange 112 and the clamping block 111 abut against both sides of the pipe 2. The second limiting flange 113 can serve as a handle for the clamping rod 110, allowing the operator to pull the clamping rod 110 outwards. Before placing pipe 2 into the U-shaped frame 109, the operator needs to hold the second limiting flange 113 and pull the clamping rod 110 outwards to increase the distance between the clamping rod 110 and the clamping block 111, allowing pipe 2 to smoothly enter the U-shaped frame 109. After pipe 2 enters the designated position, the clamping rod 110 moves towards the clamping block 111 under the elastic force of the elastic element 114, eventually causing the first limiting flange 112 to abut against the outer wall of pipe 2. At this time, the other side of pipe 2 abuts against the clamping block 111. The clamping block 111 is fixed to the inner wall of the U-shaped frame 109 with screws. Since the clamping rod 110 is a movable part and the clamping block 111 is a fixed part, only the clamping rod 110 needs to be moved during the clamping and fixing of pipe 2.

[0031] In some embodiments, please refer to Figure 7 The elastic element 114 is a compression spring, fitted onto the clamping rod 110. One end of the elastic element 114 abuts against the first limiting flange 112, and the other end abuts against the inner wall of the U-shaped frame 109. In this embodiment, the elastic element 114 is a compression spring, fitted onto the clamping rod 110. The clamping rod 110 limits the compression spring, effectively preventing it from undergoing significant torsional deformation. The compression spring remains in a compressed state at all times. Both ends of the compression spring abut against the end face of the first limiting flange 112 and the inner wall of the U-shaped frame 109, respectively. The first limiting flange 112 is threadedly connected to the clamping rod 110. After removing the first limiting flange 112 from the clamping rod 110, the clamping rod 110 can be removed from the U-shaped frame 109.

[0032] In some embodiments, please refer to Figure 5 The side of the clamping block 111 facing the clamping rod 110 is an inclined surface 115, which slopes downwards towards the side closer to the clamping rod 110. In this embodiment, the clamping block 111 is a right trapezoid. The inclined surface 115 is the side of the clamping block 111 facing the clamping rod 110. The pipe 2 rests against the inclined surface 115. The force exerted by the pipe 2 on the inclined surface 115 consists of two components: one component is the lateral force exerted by the pipe 2 on the inclined surface 115 under the action of the clamping rod 110; the other component is the longitudinal force exerted by the pipe 2 on the inclined surface 115 under its own weight. Therefore, the inclined surface 115 can provide an upward supporting force to the pipe 2, thereby improving the stability of the pipe 2 on the U-shaped frame 109.

[0033] In some embodiments, please refer to Figures 3 to 5A safety chain 116 is installed at the bottom opening of the U-shaped frame 109. In this embodiment, pins 117 are provided at both ends of the safety chain 116 along its length. The two pins 117 are located on both sides of the U-shaped frame 109. Insertion holes for engaging the pins 117 are provided on the two outer walls of the U-shaped frame 109. The insertion holes are perpendicular to the length of the pipe 2, so the safety chain 116 is detachably connected to the U-shaped frame 109. After the pipe 2 is installed in place within the U-shaped frame 109, the safety chain 116 is installed on the U-shaped frame 109. The safety chain 116 is located below the pipe 2 and is used to seal the bottom opening of the U-shaped frame 109. At this time, there is a certain gap between the safety chain 116 and the pipe 2. Only when the clamping action of the clamping rod 110 and the clamping block 111 on the pipe 2 fails will the pipe 2 fall onto the safety chain 116, thereby preventing the pipe 2 from falling directly to the ground and causing a safety accident. The safety chain 116 can only be opened after the two sets of pipes 2 are connected in place. Since the pin 117 connecting the safety chain 116 and the U-shaped frame 109 is located outside the U-shaped frame 109 and perpendicular to the pipe 2, when the pipe 2 falls on the safety chain 116, the safety chain 116 is subjected to a downward force exerted by the pipe 2, while the pin 117 is subjected to a force that includes not only a downward force but also a force toward the inside of the U-shaped frame 109. Therefore, the pin 117 will not come out of the socket during the process of the safety chain 116 supporting the pipe 2.

[0034] In some embodiments, please refer to Figure 6 A protective cover 118 is installed on the frame 1 to cover the worm gear 104 and the worm 105. In this embodiment, one end of the rotating shaft 101 extends to the outside of the frame 1. The worm gear 104 is installed at the end of the rotating shaft 101 located on the outside of the frame 1. The worm 105 is rotatably mounted on the frame 1 and is arranged vertically. The protective cover 118 is fixed to the outer wall of the frame 1 with screws, thereby covering the worm gear 104 and the worm 105. This not only protects the worm gear 104 and the worm 105 but also prevents accidents caused by accidental contact by the operator. A handle is installed on the top of the worm 105, and the handle is located outside the protective cover 118, making it convenient for the operator to drive the worm 105 to rotate.

[0035] In some embodiments, please refer to Figure 2 The frame 1 is equipped with casters 119 at its bottom. In this embodiment, four casters 119 are installed at the bottom of the frame 1. The casters 119 are omnidirectional casters, so the frame 1 can transport the pipe 2 to the designated installation area and facilitate the adjustment of the horizontal position of the pipe 2. Handrails 121 are installed at the top of both ends of the frame 1 along its length. Operators can push the entire electromechanical pipe installation device by holding the handrails 121 and move it to the designated position.

[0036] In some embodiments, please refer to Figure 1 A lifting ring 120 is installed on the top surface of the frame 1. In this embodiment, the top surface of the frame 1 is flat, and lifting rings 120 are installed at each of its four corners. The lifting rings 120 are fixed to the frame 1 by threaded connections. When the installation position of the pipe 2 is too high, it is necessary to use hoisting equipment to lift the entire electromechanical pipe installation device of this application, thereby transporting the pipe 2 to the designated height. The hook of the hoisting equipment is hung on the lifting ring 120, thereby facilitating the hoisting operation of the electromechanical pipe installation device of this application.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
