Technical Field
[0001] This invention belongs to the field of hole-opening equipment technology, specifically a clamp-type mechanical hole-opening and connection integrated device for subway water supply and drainage pipes. Background Technology
[0002] A subway is a type of urban rail transit system, referring to a high-speed, high-capacity rail transit system built in cities that uses electric traction.
[0003] However, in the existing technology, when mechanically opening and connecting branch pipes with clamps on the installed main water supply and drainage pipes in the electromechanical installation project of the subway station, there are engineering problems such as poor opening positioning accuracy, incomplete cleaning of opening burrs leading to sealing failure, and low efficiency of traditional step-by-step operation. Summary of the Invention
[0004] The purpose of this invention is to provide an integrated mechanical hole-opening and connection device for subway water supply and drainage pipes, which can efficiently perform hole-opening and connection pre-treatment at designated locations of specified drainage main pipes.
[0005] The technical solution adopted in this invention is as follows: A clamp-type mechanical drilling and connection integrated device for subway water supply and drainage pipes, comprising: an adjustment mechanism for providing a processing foundation for drilling and connection; and A limiting mechanism is used to improve the stability of the adjustment mechanism, and the limiting mechanism is disposed on the adjustment mechanism.
[0006] The adjustment mechanism includes a base plate, a drill rod, a placement frame, and an adjustment component. A limiting plate is fixedly connected to one outer surface of the base plate. The drill rod is slidably inserted into the top of the limiting plate. A positioning drill bit is fixedly connected to the bottom end of the drill rod. An opening drill bit is sleeved on the outer surface of the drill rod. The placement frame is fixedly connected to one outer surface of the base plate. The adjustment component is disposed on the base plate.
[0007] The drilling bit has a limiting groove on its outer surface, a grinding ring is fitted inside the limiting groove, and an exhaust pipe is passed through the top of the limiting plate.
[0008] The inner wall of one side of the placement frame is fixedly connected to a carrier rod, and the outer surface of the carrier rod is threaded with two limiting rings.
[0009] The adjusting component includes a limiting rod and two bidirectional threaded rods. The limiting rod is threaded to the top of the base plate, and the two bidirectional threaded rods are rotatably connected to the bottom of the base plate. Each bidirectional threaded rod has a connecting gear sleeved on its outer surface, and the two connecting gears mesh.
[0010] The bottom of the base plate has two limiting grooves, the outer surface of the limiting rod is threaded with a positioning nut, and the bottom end of the limiting rod is rotatably connected with an elastic patch.
[0011] The limiting mechanism is provided in four sets. Each set of the limiting mechanism includes a movable frame, two locking blocks and two abutting rods. The movable frame is threaded to the outer surface of the corresponding bidirectional threaded rod. The top of each movable frame extends into the corresponding limiting groove. The two locking blocks are fixedly connected to the inside of the movable frame. The two abutting rods slide through the outer surface of one side of the corresponding locking block.
[0012] Each of the abutment rods has multiple positioning holes equidistantly spaced on its outer surface, and each of the locking blocks has a positioning bolt threaded onto its outer surface. One end of each positioning bolt extends into the corresponding positioning hole.
[0013] Among them, one end of four of the abutment rods is fixedly connected to a first support wheel, and one end of the other four abutment rods is fixedly connected to a second support wheel.
[0014] A method for using a clamp-type mechanical drilling and connection integrated device for subway water supply and drainage pipes includes the following steps: S1. Hole Opening Process: By rotating one of the bidirectional threaded rods, and under the action of two connecting gears, the two bidirectional threaded rods rotate in opposite directions at all times. When the two sets of limiting mechanisms on the same bidirectional threaded rod approach each other, the four first support wheels gradually approach and fit against the outer surface of the pipe. During this process, the two sets of limiting mechanisms on the other bidirectional threaded rod move away from each other, causing the four second support wheels to gradually move away from the outer surface of the pipe. Supported by the four first support wheels, the adjusting mechanism can perform circular rotation adjustment along the outer surface of the pipe at a designated position. When the adjusting mechanism rotates to the designated position, by rotating the adjusting limit bolt, the limit bolt can be pressed against the outer surface of the pipe by the elastic patch, thereby fixing the position of the base plate. At this time, the drill rod can be easily connected to the existing electric drill equipment, and then driven by the existing electric drill equipment, the drill rod can synchronously drive the positioning. The drill bit and the drilling bit rotate, which in turn squeezes the drill rod to approach the pipe, allowing the positioning drill bit to make priority contact with the outer surface of the pipe and form a stable drilling point. Then, by continuing to squeeze the drill rod, the drilling bit can gradually make contact with the outer surface of the pipe. At this time, under the position restriction of the positioning drill bit, the drilling bit can stably perform the drilling treatment at the specified position of the pipe. When the drilling bit enters the pipe to a certain depth, the grinding ring can grind the inner wall of the hole in time under the action of the drilling bit, so as to avoid irregular burrs in the hole affecting subsequent processing. When it is necessary to drill holes at different positions of the pipe, the limit rod is released from the squeeze of the pipe. By rotating one of the bidirectional threaded rods in the opposite direction, the four first support wheels gradually move away from the pipe, while the four second support wheels squeeze and fit against the pipe. Then, with the support of the four second support wheels, the adjustment mechanism can be easily moved along the extension direction of the pipe. S2. Pre-treatment: During the drilling process, the existing air supply equipment can be connected via an exhaust pipe to quickly blow away debris generated during drilling. This allows for rapid heat dissipation at the drilling location. Existing sealing tape is then applied to the outer surface of the support rod. The positions of the two limiting rings are adjusted by rotation to restrict the sealing tape from being positioned on one side of the hole. The limiting rod is then released, and the adjustment mechanism is rotated along the outer surface of the pipe under the support of four first support wheels. This allows the sealing tape to quickly and smoothly wrap and seal the hole. When installing connecting pipe fittings at the drilling location, the sealing tape at the hole is punctured, and the connecting pipe fitting is inserted into the hole for connection. This provides an initial sealing effect for the connecting pipe fittings and prevents foreign matter remaining on the outer surface of the pipe from affecting subsequent connection procedures.
[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In this invention, during use, by rotating one of the bidirectional threaded rods, and then under the action of the two connecting gears, the two bidirectional threaded rods are kept rotating in opposite directions at all times. When the two sets of limiting mechanisms on the same bidirectional threaded rod approach each other, the four first support wheels can gradually approach and fit against the outer surface of the pipe. During this process, the two sets of limiting mechanisms on the other bidirectional threaded rod move away from each other, and the four second support wheels gradually move away from the outer surface of the pipe. Under the support of the four first support wheels, the adjusting mechanism can perform annular rotation adjustment along the outer surface of the pipe at a specified position. When the adjusting mechanism rotates to the specified position, by rotating the adjusting limit bolt, the limit bolt can be pressed against the outer surface of the pipe by the elastic patch, and thus the position of the base plate can be fixed. At this time, the drill rod can be conveniently connected to the existing electric drill equipment. Then, under the drive of the existing electric drill equipment, the drill rod can synchronously drive the positioning drill bit and the drilling drill bit. The drill rod rotates, and by squeezing the drill rod, it approaches the pipe, allowing the positioning drill bit to preferentially contact the outer surface of the pipe and form a stable drilling point. Continued squeezing of the drill rod allows the drilling drill bit to gradually contact the outer surface of the pipe. Under the positional constraint of the positioning drill bit, the drilling drill bit can stably perform drilling at the designated location on the pipe. When the drilling drill bit enters the pipe to a certain depth, the grinding ring, driven by the drilling drill bit, promptly grinds the inner wall of the hole, preventing irregular burrs from affecting subsequent processing. When drilling at different locations on the pipe is required, the limiting rod is released from squeezing the pipe. By rotating one of the bidirectional threaded rods in the opposite direction, the four first support wheels gradually move away from the pipe, while the four second support wheels press against and adhere to the pipe. Supported by the four second support wheels, the adjustment mechanism can be easily moved along the pipe's extension direction, enabling the equipment to efficiently perform pipe drilling.
[0016] (2) In this invention, during the process of drilling holes on the pipe surface, the exhaust pipe can be connected to the existing air conveying equipment, so that the waste generated during the drilling process can be blown away quickly. By quickly dissipating the temperature at the drilling position, the drilling bit can be efficiently performed to achieve its intended function. The existing sealing tape is placed on the outer surface of the carrier rod, and the positions of the two limit rings are rotated and adjusted, so that the existing sealing tape can be restricted to one side of the hole. Then the limit rod is released, and the adjustment mechanism is rotated along the outer surface of the pipe under the support of the four first support wheels, so that the existing sealing tape can be quickly and smoothly wrapped and sealed at the hole. When it is necessary to set the connecting pipe at the drilling position, the sealing tape at the hole position is punctured, and the connecting pipe is inserted into the hole for connection. The sealing tape can provide the initial sealing effect for the connecting pipe, and at the same time, it can prevent foreign objects remaining on the outer surface of the pipe from affecting the subsequent connection of the connecting pipe, improve the actual use effect of the equipment, and enable the equipment to efficiently perform its intended function.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0020] For examples, please refer to [link / reference]. Figures 1-4 A mechanical opening and connection device for subway water supply and drainage pipe clamps, consisting of an adjustment mechanism 1 and a limiting mechanism 2.
[0021] The details are as follows: Please see Figure 5 and Figure 6The adjustment mechanism 1 provides a foundation for drilling and connection. The adjustment mechanism 1 includes a base plate 101, a drill rod 110, a placement frame 107, and an adjustment component. A limiting plate is fixedly connected to one outer surface of the base plate 101. The drill rod 110 is slidably inserted into the top of the limiting plate. A positioning drill bit 113 is fixedly connected to the bottom end of the drill rod 110. A drilling drill bit 111 is sleeved on the outer surface of the drill rod 110. The placement frame 107 is fixedly connected to one outer surface of the base plate 101. The adjustment component is mounted on the base plate 101. A limiting groove is formed on the outer surface of the drilling drill bit 111. A grinding ring 112 is sleeved inside the limiting groove. An exhaust pipe 114 passes through the top of the limiting plate. A carrier rod 108 is fixedly connected to the inner wall of one side of the placement frame 107. Two threads are connected to the outer surface of the carrier rod 108. The limiting ring 109 and the adjusting component include a limiting rod 104 and two bidirectional threaded rods 102. The limiting rod 104 is threaded to the top of the base plate 101, and the two bidirectional threaded rods 102 are rotatably connected to the bottom of the base plate 101. Each bidirectional threaded rod 102 has a connecting gear 103 fitted on its outer surface. The two connecting gears 103 mesh. Two limiting grooves are provided at the bottom of the base plate 101. A positioning nut 106 is threaded to the outer surface of the limiting rod 104, and an elastic patch 105 is rotatably connected to the bottom end of the limiting rod 104. By rotating one of the bidirectional threaded rods 102, and then under the action of the two connecting gears 103, the two bidirectional threaded rods 102 are kept rotating in opposite directions at all times. Thus, when the two sets of limiting mechanisms on the same bidirectional threaded rod 102 are engaged, the limiting mechanism is adjusted accordingly. 2. When they approach each other, the four first support wheels 204 gradually approach and fit against the outer surface of the pipe 3. During this process, the two sets of limiting mechanisms 2 on the other bidirectional threaded rod 102 move away from each other, thereby causing the four second support wheels 205 to gradually move away from the outer surface of the pipe 3. Under the support of the four first support wheels 204, the adjusting mechanism 1 can rotate in a ring along the outer surface of the pipe 3 at a specified position. When the adjusting mechanism 1 rotates to the specified position, the limiting bolt is adjusted by rotating the limiting bolt, so that the limiting bolt can be pressed against the outer surface of the pipe 3 by the elastic patch 105, thereby fixing the position of the base plate 101. At this time, the drill rod 110 can be easily connected to the existing electric drill equipment, and then driven by the existing electric drill equipment, the drill rod 110... The positioning drill bit 113 and the drilling drill bit 111 can be rotated simultaneously, thereby squeezing the drill rod 110 to approach the pipe 3. This allows the positioning drill bit 113 to preferentially contact the outer surface of the pipe 3 and form a stable drill point. Further squeezing of the drill rod 110 allows the drilling drill bit 111 to gradually contact the outer surface of the pipe 3. Under the positional constraint of the positioning drill bit 113, the drilling drill bit 111 can stably perform drilling at the designated location in the pipe 3. When the drilling drill bit 111 enters the pipe 3 to a certain depth, the grinding ring 112, driven by the drilling drill bit 111, can promptly grind the inner wall of the drilled hole, preventing irregular burrs from affecting subsequent processing. This mechanism can be used when drilling is required at different locations in the pipe 3.The limiting rod 104 releases pressure on the pipe 3. By rotating one of the bidirectional threaded rods 102 in the opposite direction, the four first support wheels 204 gradually move away from the pipe 3, while the four second support wheels 205 press against the pipe 3. Supported by the four second support wheels 205, the adjusting mechanism 1 can be easily moved along the extension direction of the pipe 3, enabling the equipment to efficiently perform drilling on the pipe 3. During the drilling process, the exhaust pipe 114 can be connected to existing air conveying equipment, allowing the waste generated during drilling to be quickly blown away. This rapid dissipation of heat at the drilling location ensures that the drilling bit 111 can efficiently perform its intended function. The existing sealing tape is applied to the outer surface of the carrier rod 108. The positions of the two limiting rings 109 are adjusted by rotation, thus restricting the existing sealing tape from being positioned on one side of the opening. The limiting rod 104 is then released, and the adjusting mechanism 1 is rotated along the outer surface of the pipe 3 under the support of the four first support wheels 204. This allows the existing sealing tape to quickly and smoothly wrap and seal the opening. When a connecting pipe fitting needs to be installed at the opening, the sealing tape at the opening is punctured, and the connecting pipe fitting is inserted into the opening for connection. This provides an initial sealing effect for the connecting pipe fitting and prevents foreign matter remaining on the outer surface of the pipe 3 from affecting subsequent connection processing. Please see Figure 7 and Figure 8 The limiting mechanism 2 is used to improve the stability of the adjusting mechanism 1. The limiting mechanism 2 is set on the adjusting mechanism 1, and there are four sets of limiting mechanisms 2. Each set of limiting mechanisms 2 includes a movable frame 201, two locking blocks 202 and two abutting rods 203. The movable frame 201 is threaded to the outer surface of the corresponding bidirectional threaded rod 102. The top of each movable frame 201 extends into the corresponding limiting groove. The two locking blocks 202 are fixedly connected to the inside of the movable frame 201. The two abutting rods 203 slide through the outer surface of one side of the corresponding locking block 202. The outer surface of each abutting rod 203 has multiple positioning holes equidistantly opened. The outer surface of each locking block 202 is threaded with a positioning bolt 206. One end of each positioning bolt 206 has Extending into the corresponding positioning holes, one end of each of the four abutment rods 203 is fixedly connected to a first support wheel 204, and one end of each of the other four abutment rods 203 is fixedly connected to a second support wheel 205. Supported by the four first support wheels 204, the adjustment mechanism 1 can rotate in a ring along the outer surface of the pipe 3 at a specified position. Supported by the four second support wheels 205, the adjustment mechanism 1 can be easily moved along the extension direction of the pipe 3. At the same time, according to the specifications of the pipe 3, the length of the abutment rod 203 in the moving block 202 is used to limit the length of the abutment rod 203 under the action of the positioning bolt 206 and the positioning hole, so that the equipment can meet the use of pipes of different specifications and improve the versatility of the equipment in actual use.
[0022] The following is a detailed description of the method of using a clamp-type mechanical drilling and connection integrated device for subway water supply and drainage pipes provided by an embodiment of the present invention. The method of use includes the following steps: Step 1, Hole Opening Process: By rotating one of the bidirectional threaded rods 102, and then under the action of the two connecting gears 103, the two bidirectional threaded rods 102 are kept rotating in opposite directions. When the two sets of limiting mechanisms 2 on the same bidirectional threaded rod 102 approach each other, the four first support wheels 204 gradually approach and conform to the outer surface of the pipe 3. During this process, the two sets of limiting mechanisms 2 on the other bidirectional threaded rod 102 move away from each other, causing the four second support wheels 205 to gradually move away from the outer surface of the pipe 3. Supported by the first support wheel 204, the adjustment mechanism 1 can rotate circumferentially along the outer surface of the pipe 3 at a designated position. When the adjustment mechanism 1 rotates to the designated position, the limit bolt is adjusted by rotating it, so that the limit bolt can be pressed against the outer surface of the pipe 3 by the elastic patch 105, thereby fixing the base plate 101 in its position. At this time, the drill rod 110 can be easily connected to the existing electric drill equipment, and then, driven by the existing electric drill equipment, the drill rod 110 can synchronously drive the positioning drill bit 113 and the drilling drill bit 111 to rotate. Then, by squeezing the drill rod 110 closer to the pipe 3, the positioning drill bit 113 can preferentially contact the outer surface of the pipe 3 and form a stable drill point. Then, by continuing to squeeze the drill rod 110, the drilling drill bit 111 can gradually contact the outer surface of the pipe 3. At this time, under the positional constraint of the positioning drill bit 113, the drilling drill bit 111 can stably perform the drilling treatment at the designated location in the pipe 3. When the drilling drill bit 111 enters the pipe 3 to a certain depth, the grinding ring 112 can promptly clean the drilled area under the action of the drilling drill bit 111. The inner wall of the hole is polished to avoid irregular burrs from affecting subsequent processing. When it is necessary to open holes at different positions of the pipe 3, the limit rod 104 is released to squeeze the pipe 3. By rotating one of the bidirectional threaded rods 102 in the opposite direction, the four first support wheels 204 are gradually moved away from the pipe 3. At the same time, the four second support wheels 205 are squeezed and pressed against the pipe 3. Then, under the support of the four second support wheels 205, the adjustment mechanism 1 can be easily moved along the extension direction of the pipe 3, so that the equipment can efficiently open holes in the pipe 3. Step 2, Connection Pre-treatment: During the drilling process on the surface of pipe 3, the existing air conveying equipment can be connected through the exhaust pipe 114 to quickly blow away the debris generated during the drilling process. This allows for rapid heat dissipation at the drilling location, ensuring that the drilling bit 111 can efficiently perform its intended function. The existing sealing tape is then fitted onto the outer surface of the carrier rod 108. The positions of the two limit rings 109 are adjusted by rotation to restrict the existing sealing tape from being positioned on one side of the drilled hole. The limit rod 104 is then released, and the fourth... Supported by a support wheel 204, the adjusting mechanism 1 rotates along the outer surface of the pipe 3, enabling the existing sealing tape to quickly and smoothly wrap and seal the hole. When it is necessary to install connecting pipe fittings at the opening, the sealing tape at the hole is punctured, and the connecting pipe fittings are inserted into the hole for connection. This allows the sealing tape to provide an initial sealing effect for the connecting pipe fittings, while preventing foreign objects remaining on the outer surface of the pipe 3 from affecting the subsequent connection of the connecting pipe fittings. This improves the actual use effect of the equipment and enables the equipment to efficiently perform its intended functions.

Then the limit rod (104) is released, and the adjustment mechanism (1) is rotated along the outer surface of the pipe (3) under the support of the four first support wheels (204) so that the existing sealing tape can be quickly and smoothly wrapped and sealed at the hole. When it is necessary to set the connecting pipe at the opening position, the sealing tape at the hole position is punctured and the connecting pipe is inserted into the hole for connection treatment. The sealing tape can provide the initial sealing effect of the connecting pipe, and at the same time, it can avoid the foreign matter remaining on the outer surface of the pipe (3) from affecting the subsequent connection treatment of the connecting pipe.
