[0001] The utility model relates to the technical field of operating tools, in particular to a nylon sleeve replacement device using a tapping method. Background Art
[0002] With the continuous expansion of the subway network and the passage of operation time, some subway lines have gradually experienced the failure of the embedded nylon sleeves in the prefabricated reinforced concrete sleepers, which has a great impact on the safety of subway operations. In order to deal with the safety hazards in a timely and effective manner, it is necessary to replace the embedded nylon sleeves in the prefabricated reinforced concrete sleepers. However, subway line maintenance generally has the characteristics of short operation time, heavy operation tasks, and high reliability requirements.
[0003] Previously, there were three main methods for replacing failed casings: hot melt method, anchor tool change method, and water drilling method. The hot melt method has a large environmental pollution, high equipment cost, and the hot melt cutter head is easily damaged, with high maintenance cost and difficulty. The anchor tool change method is relatively new, with high equipment cost, and the equipment is large and has certain limitations in use. When replacing the casing with the water drilling method, the original concrete holes and the embedded steel structure of the sleeper will be destroyed. The replacement process is complicated and cement mortar needs to be poured to restore the original holes. The restored holes need to be filled twice, so there is instability in concrete pouring and a limitation on the service life.
[0004] Therefore, it is necessary to provide a new tapping method nylon sleeve replacement device to solve the above-mentioned technical problems. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0026] See also Figures 1 to 4 The utility model embodiment provides a nylon sleeve replacement device using a tapping method, and the nylon sleeve replacement device using a tapping method includes: a support frame 1.
[0027] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 , threaded fixing pins 13 are inserted at the four corners of the outside of the support frame 1, a fixedly connected top frame 11 is mounted on the top of the support frame 1, a rotating rod 2 is threadedly connected to the top frame 11 and the center of the inside of the support frame 1, and a movably connected tapping drill bit 23 is provided at the bottom end of the rotating rod 2.
[0028] It should be noted that the overall structure is simple. When used later, the construction personnel only need to hold the handle 21 of the device to give power to the tapping drill bit 23. The drill bit will drill into the hole according to the action of the drill thread. At this time, the nylon casing to be replaced is tapped by the tapping drill bit 23. The nylon casing is spirally screwed out from the drill bit gap until the drill bit drills to the bottom of the casing. The nylon casing can be completely cleared out of the hole. The nylon casing in the hole disappears. Then the tapping drill bit 23 is taken out, and the new nylon casing is directly screwed into the concrete hole of the sleeper. The replacement operation of the nylon casing is completed once, which is very convenient and quick.
[0029] By setting the tapping drill bit 23 on the support frame 1 through the rotating rod 2 at the top, when drilling later, the rotating rod 2 located inside the support frame 1 can smoothly guide and position the movement of the tapping drill bit 23, thereby making the later movement of the tapping drill bit 23 more stable, so that it can drill stably.
[0030] In the embodiments of the present invention, please refer to Figure 1 and Figure 4A movably connected support ring 3 is provided at the center of the top of the support frame 1, a laser pen 31 is provided at the center inside the support ring 3, and the centers of the laser pen 31, the rotating rod 2 and the tapping drill bit 23 are on the same axis, a fixedly connected fixing cylinder 12 is provided at the center of the top of the support frame 1, and the outer wall of the fixing cylinder 12 is threadedly connected to the inner wall of the support ring 3.
[0031] It should be noted that: by connecting the support ring 3 with the center of the top of the support frame 1 and setting a laser pen 31 in the center of the support ring 3, before use later, it can be smoothly aligned with the reference point of the required tapping part through the irradiation of the laser pen 31, so that the staff can fix the support frame 1 smoothly, and then the tapping drill bit 23 can drill more accurately later.
[0032] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 The rotating rod 2 is a T-shaped structure, and the ends of both sides of the top of the rotating rod 2 are inserted with threaded handles 21, the bottom end of the rotating rod 2 is provided with a connecting groove 22, and the interior of the connecting groove 22 is a rectangular structure, the top of the tapping drill bit 23 is provided with a connecting block 24, and the outer wall of the connecting block 24 is abutted against and slidably connected to the inner wall of the connecting groove 22, and a connecting hole 25 is provided in the center of the corresponding part of the inner wall of the rotating rod 2 and the connecting block 24, and a threaded connecting pin 26 is inserted into the interior of the connecting hole 25.
[0033] It should be noted that: by setting the connecting block 24 and the connecting groove 22 as a rectangular structure, when tapping and drilling are performed later, the rectangular structure can increase the resistance of the connection between the connecting block 24 and the rotating rod 2, thereby preventing the connecting block 24 from rotating. At the same time, it can also reduce the force generated by the resistance on the connecting pin 26 during the tapping process later, causing the connecting pin 26 to be bent and damaged. By limiting the position of the connecting pin 26, the staff can flexibly replace the tapping drill bit 23 as needed during the later use, thereby improving the scope of application of the device in the later stage.
[0034] By inserting threaded handles 21 on both sides of the top of the rotating rod 2, the staff can flexibly disassemble the rotating rod 2 and the handle 21 later, and the staff can flexibly change the length of the handle 21 according to needs later, making the staff's later use more flexible.
[0035] The working principle of the tapping method nylon casing replacement device provided by the utility model is as follows:
[0036] When using the device later, the staff can firstly sleeve the support ring 3 on the outside of the fixed tube 12 through the threaded structure, and then smoothly install the laser pen 31 inside the support ring 3 at the center of the support inside, so that it is on the same center line as the center of the support frame 1 and the top frame 11. At this time, the staff can turn on the laser pen 31 and smoothly move the support frame 1. When the laser beam emitted by the laser pen 31 successfully coincides with the marking point of the required drilling;
[0037] The surrounding ground can be smoothly leveled, and then the support frame 1 can be fixed to the ground through the fixing pin 13, and then the support ring 3 can be taken out from the outside of the fixing cylinder 12, and the rotating rod 2 can be smoothly inserted into the top frame 11 and the inside of the support frame 1 through the threaded structure. When the bottom end of the rotating rod 2 smoothly extends to the inside of the support frame 1, the required adapted tapping drill bit 23 can be taken out and smoothly inserted into the connecting groove 22 at the bottom of the rotating rod 2, and then the connecting pin 26 can be taken out and inserted into the connecting hole 25 to smoothly fix the connection between the tapping drill bit 23 and the rotating rod 2;
[0038] At this time, the staff can hold the handle 21 to give power to the rotating rod 2, and the rotating rod 2 can smoothly move downward in a spiral manner inside the top frame 11 and the support frame 1 through the threaded structure. In the process of the rotating rod 2 moving downward, the tapping drill bit 23 can be smoothly driven to move, providing power for the tapping drill bit 23, and the tapping drill bit 23 can drill into the hole according to the drill thread. At this time, the nylon casing to be replaced is tapped by the tapping drill bit 23, and the nylon casing is spirally screwed out from the drill bit gap until the tapping drill bit 23 drills to the bottom of the casing, and the nylon casing can be completely cleared out of the hole. When the nylon casing in the hole disappears, the rotating rod 2 can be controlled in the reverse direction to rotate, so that the tapping drill bit 23 is taken out, and the new nylon casing is directly screwed into the concrete hole of the sleeper, that is, the replacement of the nylon casing is completed, and the whole operation process is very convenient and fast.
