Description

Technical Field

[0001] The invention relates to a pipe penetration device, in particular to a pipe penetration device used for penetrating pipes in a pipe gallery, and belongs to the technical field of pipe gallery pipeline installation and construction. Background Art

[0002] During the construction process of arranging pipelines on the steel structure pipe gallery, it is necessary to pass various specifications of pipelines through the steel structure of the pipe gallery and adjust their positions to cooperate with the construction work and fixed placement. Due to the characteristics of heavy and long pipelines, the existing technology usually adopts manual or hand winch to drag. This not only wastes a lot of manpower and material resources, but also the sliding friction between the pipeline and the pipe gallery can easily damage the anti-corrosion paint on the surface of the pipeline, the metal on the surface of the pipeline and the fire-retardant coating on the surface of the pipe gallery, causing the anti-corrosion paint of the pipeline to fall off, the metal on the surface of the pipeline to be scratched and damaged, and the fire-retardant coating of the pipe gallery to fall off. The protection of the pipeline and the pipe gallery is not in place, affecting the quality of the pipeline, not meeting the quality requirements of pipeline installation, and the construction efficiency is low.

[0003] At present, a Chinese invention patent with announcement number CN206478312U discloses a pipe gallery pipe threader, including a pulley, a support platform, an adjustable top screw, a support, a slot and a hinge. There are two pulleys and two support platforms, and there are several adjustable top screws. The pulley, the support platform and the adjustable top screw are symmetrically arranged with the center of the support. The pulley is fixed to the support platform through a bracket, and the inner side of the support platform is fixed to the middle of the support through a hinge. The support below the outer side of the support platform is provided with a threaded hole, and the adjustable top screw passes through the threaded hole to lift the outer side of the support platform. A slot is provided below the support, and the slot is a U-shaped slot. However, this pipe threader has the following disadvantages: 1. The bottom of the pipe threader is a U-shaped slot. When it is fixed on the crossbeam of the pipe gallery for pipe threading, there is no U-shaped slot locking device, so the pipe threader cannot be effectively fixed on the pipe gallery, and it cannot be applied to pipe galleries of various specifications and sizes; 2. For pipe threading operations of different specifications of pipes, it is necessary to adjust the inclination angle of the two pulleys, which is cumbersome and difficult to operate; 3. Since the contact points between the pipeline and the pipe threader are only the vertices of the two pulleys, there are only two points of contact and no unlimited position measures. During the pipe threading operation, it is easy for the pipeline to fall off, causing safety accidents; 4. Due to too many active points of parts, the pipe threader is easily damaged and cannot withstand the pipe threading operations of larger specifications of pipelines.

[0004] At present, the Chinese invention patent with the announcement number CN111457155B discloses a suspended progressive pipe-threading device and method, which includes a frame for carrying pipes and a walking device that can move on the top beam in the pipe gallery; the walking device is arranged above the frame; the frame is provided with a roller for supporting the pipe and perpendicular to the center line of the pipe. However, the pipe-threading device used in this method is relatively complex, with high manufacturing costs, and it is difficult to ensure safety when it is fixed on the pipe gallery.

[0005] At present, the Chinese invention patent with announcement number CN103527845A discloses a method for pipe threading in a pipe gallery by using a track and a trolley to cooperate with each other, wherein an I-shaped rail is provided on the crossbeam of the pipe gallery, at least one track trolley is provided on the I-shaped rail, and a pipe support plate is provided on the track trolley; the open end of the I-shaped rail is placed upward to form two rails for cooperating with the track trolley. However, the track and the trolley cooperate with each other to perform pipe threading in the pipe gallery, and this method of pipe threading is too cumbersome and requires multiple auxiliary tools.

[0006] Therefore, the key to solving the above technical problems is to develop a pipe penetration device that is simple to operate, safe and reliable for pipe penetration in pipe corridors. Summary of the invention

[0042] A rotating sleeve (332) is connected to the end of the non-threaded section of the adjusting rod (331).

[0043] The working principle is: before using the pipe penetration device for pipe gallery with the above-mentioned design structure, the already manufactured pipe penetration device needs to be installed as a spare.

[0044] The specific installation steps are:

[0045] First, the operator uses a steel pipe or a crowbar with a diameter smaller than that of the rotating sleeve (332) to pass through the rotating sleeve (332) and drive the rotating adjustment rod (331) counterclockwise, and then the adjustment rod (331) drives the movable clamping assembly (32) to move outward until the distance between the movable clamping assembly (32) and the fixed clamping member (2) is greater than the target pipe gallery crossbeam (4);

[0046] Then, the operator places the entire pipe penetration device above the target pipe gallery cross beam (4), and then drops the entire pipe penetration device downward until the target pipe gallery cross beam (4) is inserted into the slot formed by the fixed clamping member (21) and the movable clamping assembly (32);

[0047] Next, the operator uses a steel pipe or a crowbar with a diameter smaller than that of the rotating sleeve (332) to pass through the rotating sleeve (332) and drive the rotating adjustment rod (331) clockwise, so that the adjustment rod (331) drives the movable clamping assembly (32) to move inward until the distance between the movable clamping assembly (32) and the fixed clamping member (2) is consistent with the width of the target tunnel crossbeam (4), and the movable clamping assembly (32) is locked by force through the rotating sleeve (332);

[0048] Finally, the operator uses the same installation method as the above-mentioned pipe penetration device to install the remaining pipe penetration devices on another pipe gallery crossbar on the same layer of the pipe gallery, so that the connection line between the multiple pipe penetration devices is parallel and in the same direction as the main pipe gallery, thus completing the installation of the present invention, and the device can be used after the installation is completed.

[0049] The specific steps are:

[0050] First, the operator fixes two or more pipe penetration devices of the present invention respectively on the front and rear beams corresponding to the pipe gallery beam (4). When multiple pipe penetration devices are fixedly installed, it is ensured that the multiple pipe penetration devices in the target area are located in the same horizontal straight line;

[0051] Then, the operator uses the lifting equipment to lift the pipe (5) to be installed to the top of the target pipe gallery, and slowly places it on the long rollers (13) of the multiple pipe threading devices, ensuring that the front and rear ends of the pipe (5) to be installed are both above the long rollers (13);

[0052] Next, the operator fastens a rope to one end of the pipe (5) to be installed;

[0053] Finally, the operator moves the pipe (5) to be installed on the long roller (13) along the specified moving direction by manually dragging, mechanically dragging or using a hand winch, thereby ultimately achieving the purpose of constructing and installing the pipe translation and welding.

[0054] As time goes by, when the construction is completed, the pipe penetration device needs to be removed. The specific removal process is:

[0055] First, the operator uses a steel pipe or a crowbar with a diameter smaller than that of the rotating sleeve (332) to pass through the rotating sleeve (332) and rotate the adjusting rod (331) counterclockwise to move the movable clamping assembly (32) outward until the distance between the movable clamping assembly (32) and the fixed clamping member (2) is greater than the target pipe gallery crossbeam (4);

[0056] Then, the operator lifts the entire pipe penetration device from above the crossbar of the target pipe gallery;

[0057] Finally, the operator uses the same method to remove the second pipe penetrater from the other corridor crossbar until all the pipe penetraters are removed. Afterwards, the operator cleans and repairs its various components and moves them manually or with corresponding handling equipment to the designated tool storage warehouse for storage in preparation for the next cycle.

[0058] Compared with the prior art, the present invention has the following beneficial effects:

[0059] 1. The present invention is simple to operate, practical and reliable, effectively guarantees the quality of the pipeline, is convenient for the next step of construction, and achieves the purpose of improving the efficiency of pipe penetration in the pipe gallery and the safety of the operation. It avoids the damage of the anti-corrosion paint on the surface of the pipeline, the metal on the surface of the pipeline and the fire-retardant coating on the surface of the pipe gallery caused by manual or hand-pulled hoists, which does not protect the pipeline and the pipe gallery in place and affects the quality of the pipeline;

[0060] 2. The present invention is safe and efficient, and can well fix the pipe threader on the crossbeam of the pipe gallery, eliminating the phenomenon of the pipe threader shaking back and forth when the pipeline moves, thereby improving construction safety, and ensuring quality and efficiency;

[0061] 3. The present invention can meet the requirements of pipe threading of pipelines of various specifications and sizes, and at the same time, the pipe threading process is changed to rolling friction, which greatly saves manpower and material resources, and also effectively protects the anti-corrosion layer of the pipeline, ensures the quality of the pipeline, and facilitates the next step of construction;

[0062] 4. The present invention changes the traditional sliding friction between the pipeline and the pipe gallery beam into a rolling friction between the pipeline and the pipe pulley, making the pipeline movement easier, reducing the number of construction personnel adjusting the hand chain hoist, improving work efficiency, and protecting the integrity of the pipeline and the pipe gallery;

[0063] 5. The pipe threader used in the present invention is equipped with limit plates on both sides to ensure the safety of the pipeline during movement. At the same time, during the movement of the pipeline, the construction safety risk caused by the extensive use of hand winches is reduced;

[0064] 6. The present invention provides anti-skid pads on the inner walls of the fixed engaging member and the movable engaging member, so that the fixing member can be better fixed on the cross beam of the pipe gallery, and the integrity of the cross beam of the pipe gallery can be better protected.

[0117] In summary, a more specific embodiment of the present invention is:

[0118] Before using the pipe penetration device for pipe gallery with the above-mentioned design structure, the already manufactured pipe penetration device needs to be installed as a spare.

[0119] The specific installation steps are:

[0120] First, the operator uses a steel pipe or a crowbar with a diameter smaller than the rotating sleeve 332 to pass through the rotating sleeve 332 and drive the rotating adjustment rod 331 counterclockwise, and then the adjustment rod 331 drives the mobile clamping assembly 32 to move outward until the distance between the mobile clamping assembly 32 and the fixed clamping member 2 is larger than the target pipe gallery beam 4;

[0121] Then, the operator places the entire pipe penetration device above the target pipe gallery cross beam 4, and then drops the entire pipe penetration device downward until the target pipe gallery cross beam 4 is inserted into the slot formed by the fixed clamping member 21 and the movable clamping assembly 32;

[0122] Next, the operator uses a steel pipe or a crowbar with a diameter smaller than the rotating sleeve 332 to pass through the rotating sleeve 332 and drive the rotating adjustment rod 331 clockwise, and then the adjustment rod 331 drives the mobile clamping assembly 32 to move inward until the distance between the mobile clamping assembly 32 and the fixed clamping member 2 is consistent with the width of the target tunnel crossbeam 4, and the mobile clamping assembly 32 is locked by the rotating sleeve 332;

[0123] Finally, the operator uses the same installation method as the above-mentioned pipe penetration device to install the remaining pipe penetration devices on another pipe gallery crossbar on the same layer of the pipe gallery, so that the connection line between the multiple pipe penetration devices is parallel and in the same direction as the main pipe gallery, thus completing the installation of the present invention, and the device can be used after the installation is completed.

[0124] The specific steps are:

[0125] First, the operator fixes two or more pipe penetration devices of the present invention on the front and rear beams corresponding to the pipe gallery beam 4, respectively. When multiple pipe penetration devices are fixedly installed, ensure that the multiple pipe penetration devices in the target area are located in the same horizontal straight line;

[0126] Then, the operator hoists the pipe 5 to be installed to the top of the target pipe gallery through the hoisting equipment, and slowly places it on the long rollers 13 of multiple pipe threaders, ensuring that the front and rear ends of the pipe 5 to be installed are both above the long rollers 13;

[0127] Next, the operator fastens a rope on one end of the pipe 5 to be installed;

[0128] Finally, the operator moves the pipe 5 to be installed on the long roller 13 along the specified moving direction by manual dragging, mechanical equipment dragging or hand winch, and finally achieves the purpose of pipeline translation and weld jointing during construction and installation.

[0129] As time goes by, when the construction is completed, the pipe penetration device needs to be removed. The specific removal process is:

[0130] First, the operator uses a steel pipe or a crowbar with a diameter smaller than the rotating sleeve 332 to pass through the rotating sleeve 332 and rotate the adjusting rod 331 counterclockwise to move the movable clamping assembly 32 outward until the distance between the movable clamping assembly 32 and the fixed clamping member 2 is larger than the target pipe gallery crossbeam 4;

[0131] Then, the operator lifts the entire pipe penetration device from above the crossbar of the target pipe gallery;

[0132] Finally, the operator uses the same method to remove the second pipe penetrater from the other corridor crossbar until all the pipe penetraters are removed. Afterwards, the operator cleans and repairs its various components and moves them manually or with corresponding handling equipment to the designated tool storage warehouse for storage in preparation for the next cycle.

[0133] In the present invention, the support platform 11 is used to connect the limit plate 12, the long roller 13, and the fixed clamping member 21. It is the supporting base of the entire pipe threader and bears the weight of the pipe; the limit plate 12 is located on both sides of the support platform 11, and is used to limit the left and right swing amplitude of the pipe 5 during movement, ensuring that the pipe 5 moves in a straight line along the target direction; the long roller 13 is located above the support platform 11. When in use, the long roller 13 is in direct contact with the pipe 5, and the movement of the pipe 5 relative to the pipe threader is rolling friction, which firstly reduces the resistance to the movement of the pipe, and secondly protects the outer surface of the pipe to avoid friction; the bearing seat 14 is located at both ends of the long roller 13, and is used to fix the long roller 13 to avoid the movement of the long roller during use; the fastener 15 is used to connect and fasten the bearing seat 14 and the limit plate 12 of the pipe threader to the support platform 11 to ensure the operating stability of the pipe threader.

[0134] In the present invention, the fixed engaging member 21 is located below the pipe threader support platform 11 and forms an adjustable square slot with the movable engaging assembly 32. By adjusting the size of the slot, the pipe threader can be applied to pipe gallery operations of different specifications; the locking member 22 is used to connect the fixed engaging member 21 below the support platform 11 to ensure that the pipe threader is clamped and firmly on the pipe gallery;

[0135] The adjusting member support 31 is located below the support platform 11 of the pipe threader, and is used to connect the guide assembly 34 and the adjusting member 33, and has a guiding and adjusting function. The size of the square slot is adjusted by the distance between the adjusting member 33 and the adjusting member support 31; the movable clamping assembly 32 and the fixed clamping member 21 form an adjustable square slot, and the pipe threader can be applied to pipe gallery operations of different specifications by adjusting the size of the slot; the connecting plate 321 is used to connect the adjusting rod 331 and the sliding guide rod 342 and the end of the movable clamping member 322, so that when the pipe threader adjusts the size of the square slot during use, the movable clamping assembly 32 moves as a whole;

[0136] The movable clamping member 322 is mainly used to clamp the pipe gallery crossbar and fix the pipe threader. During the process of installing the pipe threader, the movable clamping member 322 gradually approaches the lower edge of the pipe gallery crossbar, and finally forms a closed and locked state for the pipe gallery, thereby ensuring the installation stability and reliability of the pipe threader. The adjusting member 33 is mainly used to adjust the size of the square card slot of the pipe threader, so that the pipe threader is suitable for pipe galleries of different specifications, as well as to lock and remove the pipe threader during installation. The adjusting rod 331 is located in the center of the connecting plate 321, and its function is to change the size of the square card slot by rotating the movable clamping member 32 to move forward and backward.

[0137] The rotating sleeve 332 is located at the end of the adjusting rod 331, and its main function is to insert a steel pipe or crowbar of appropriate size into the rotating sleeve 332 to assist the rotation adjustment; the guide assembly 34 is used to support and guide the mobile clamping assembly 32 when the size of the square slot changes; the guide rod support 341 is used to connect the two sliding guide rods 342 to provide a support point for them; the sliding guide rod 342 is used to strengthen the strength of the entire pipe threader slot, while ensuring that the mobile clamping assembly 32 does not rotate during the movement and maintains horizontal movement.

[0138] The pipe gallery pipe threader used in the present invention is as follows Figure 1-7 As shown, a pipe threader for pipe threading in a pipe gallery comprises a traction mechanism 1; a fixed clamping piece 2, which is detachably connected to one side below the traction mechanism 1; and an adjustable clamping assembly 3, which is connected to the other side below the traction mechanism 1; wherein the fixed clamping piece 2 and the adjustable clamping assembly 3 are matched to complete the fixation of the pipe gallery crossbeam 4.

[0139] In the present invention, the limit plate 12, the sliding guide rod 342, the bearing seat 14, the fixed engaging member 21 and the movable engaging member 322 are each provided with two, the long roller 13, the support platform 11, the adjusting rod 331, the adjusting member support 31, the rotating sleeve 332 are each provided with one, and the connecting components, the fasteners 15 and the locking members 22 are provided. The limit plate 12 and the bearing seat 14 are symmetrically arranged with respect to the center of the support platform 11, the two ends of the long roller 13 are connected to the limit plate 12 arranged on the support platform 11 through the bearing seat 14, and the support platform 11 is fixed to the middle part of the adjusting member support 31 through the locking member 22;

[0140] The limit plates 12 are fastened to the lower ends of the support platform 11 by fasteners 15 respectively;

[0141] The fixed engaging members 21 are respectively fastened to the center position of the bottom of the support platform 11 through the locking members 22;

[0142] In the specific embodiment of the pipe threader for the pipe gallery, since limit plates 12 are provided at both ends of the support platform 11, during the process of pipe threading during construction and installation, the pipe 5 will move in a straight line and will not move left and right. The pipe 5 contacts the pipe pulley through the pipe threader, and the sliding friction between the pipe 5 and the pipe gallery crossbeam 4 is changed to a rolling friction between the pipe 5 and the long roller 13. This avoids direct contact between the pipe 5 and the pipe gallery crossbeam 4, and changes the original sliding friction into rolling friction, thereby avoiding the friction and shedding of the surface anti-corrosion paint of the pipe 5 during construction and installation, damage to the metal surface of the pipe, and damage to the fire-retardant coating on the pipe gallery. It also greatly reduces the construction safety risks caused by the extensive use of hand winches and reduces the number of construction personnel who adjust the hand winches, thereby saving manpower and material resources, improving work efficiency and construction safety and reliability, and meeting the requirements for pipe threading in the pipe gallery.
