Description

Technical Field

[0001] This utility model relates to the field of tunnel excavation, and in particular to an efficient auxiliary tooling for excavating rail transit tunnels. Background Technology

[0002] Tunnel excavation refers to the engineering activity of excavating channels underground or underwater. This process is commonly used to construct transportation facilities such as highways, railways, and subways, as well as to lay infrastructure such as pipelines and cables.

[0003] High-efficiency rail transit tunnel excavation auxiliary tooling is a specially designed piece of equipment or system used to improve efficiency and safety during the excavation process of rail transit tunnels.

[0004] The existing high-efficiency auxiliary tooling for rail transit tunnel excavation has the following shortcomings:

[0005] In the process of excavating rail transit tunnels, auxiliary tools such as rock drilling rigs are often needed to drill holes in rocks or inner walls. However, some traditionally designed rock drilling rigs face many inconveniences during drilling operations due to their fixed drill bits. Because the drill bit position is fixed, when drilling is required in different rock locations, it cannot be achieved by simply adjusting the drill bit. The entire rock drilling rig must be moved and repositioned. This process is not only time-consuming and labor-intensive, but also difficult to operate in the limited space of the tunnel, affecting drilling efficiency. Utility Model Content

[0006] This invention greatly enhances the applicability of the equipment under different working conditions, meets diverse rock drilling needs, and solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency auxiliary tooling for railway tunnel excavation, comprising an adjustment mechanism, wherein a moving mechanism is fixedly installed on the inner wall of the adjustment mechanism; the adjustment mechanism includes a base plate, a rotating shaft is rotatably connected to the top of the base plate, a disc is fixedly connected to the top end face of the rotating shaft, a set of cylinders is fixedly connected to the inner wall of the disc, a set of insert rods is provided through the inner wall of the cylinders, a set of compression springs is sleeved on the outer wall of the insert rods, a set of pull plates is fixedly connected to the top of the insert rods, a set of first electric push rods is fixedly installed on the top of the disc, a movable plate is fixedly connected to the shaft end of the first electric push rods, a second electric push rod is fixedly installed on the top of the movable plate, and a sliding plate is slidably connected to the inner wall of the movable plate. Through the above components, the user can easily adjust the angle and height of the drill bit according to actual needs, facilitating subsequent operations on rocks at different locations.

[0008] Preferably, a set of movable rods is slidably connected to the inner wall of the base plate, and a PLC controller is fixedly installed on the top of the base plate. The top of the movable rods is fixedly connected to the bottom of the disc. The movable rods enable the stability of the disc during rotation. The PLC controller is electrically connected to the components to control the opening and closing of the components.

[0009] Preferably, a first limiting rod is fixedly connected to the top of each disc, and the outer wall of the first limiting rod is slidably connected to the inner wall of the movable plate. The stability of the movable plate during its up-and-down movement is achieved by setting the first limiting rod.

[0010] Preferably, the top of the base plate is provided with a circular hole, the inner wall of the circular hole is slidably connected to the outer wall of the insertion rod, one end of the compression spring is fixedly connected to the inner wall of the cylinder, and the other end of the compression spring is fixedly connected to the outer wall of the insertion rod. The circular hole facilitates the insertion of the insertion rod into a designated position so as to restrict the disc.

[0011] Preferably, a set of third electric push rods is fixedly installed on the outer wall of the base plate, and a set of anti-slip pads are fixedly connected to the shaft end of the third electric push rods. By setting the third electric push rods and anti-slip pads, the overall stability can be ensured and displacement can be avoided during operation.

[0012] Preferably, a set of second limiting rods is fixedly connected to the inner wall of the movable plate, the outer wall of the second limiting rods is slidably connected to the inner wall of the slide plate, and the shaft end of the second electric push rod is fixedly connected to the outer wall of the slide plate. By setting the second limiting rods, the stability of the slide plate when sliding back and forth can be achieved, so that drilling and impact operations can be carried out normally.

[0013] Preferably, a nozzle is fixedly installed on the top of the slide plate, a water tank is fixedly connected to the top of the movable plate, an inlet pipe is fixedly connected to the top of the water tank, a sealing cap is movably inserted into the inner wall of the inlet pipe, a water pump is fixedly connected to one side of the outer wall of the water tank, and a telescopic hose is fixedly connected to the output end of the water pump. The telescopic hose is connected to the inside of the nozzle. Through the nozzle, water tank, telescopic hose and inlet pipe, water can be pressurized and sprayed into the drill hole for cooling the drill bit. The telescopic hose also avoids interfering with the back-and-forth movement of the slide plate.

[0014] Preferably, a servo motor is fixedly installed on the outer wall of the slide plate, and a drill rod is fixedly connected to the output end of the servo motor. A drill bit is fixedly installed on the outer wall of the drill rod. The servo motor can drive the drill rod and the drill bit to rotate, so that the drilling operation can proceed normally.

[0015] Preferably, the moving mechanism includes a connecting column, and a damper is fixedly installed on the inner wall of each connecting column. A self-locking wheel is fixedly connected to the shaft end of each damper, and a spring is sleeved on the outer wall of each connecting column.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, through the ingenious combination of the rotating shaft and the disc, the user can easily adjust the angle of the drill bit. With the help of the movable rod, the entire angle adjustment process is smooth and stable, ensuring that the drill bit can be accurately aligned with the rock at different positions for drilling operations. When the drill bit is adjusted to the required angle, the cylinder, pull plate, compression spring, round hole and insert rod work together. With the help of their mutual cooperation, the rotation of the disc is effectively restricted, so that the drill bit is kept steadily at the specified angle, ensuring the stability of the drilling operation. Through the first electric push rod and the first limit rod, the height of the drill bit and the movable plate can be flexibly adjusted up and down, greatly enhancing the applicability of the equipment under different working conditions.

[0018] 2. In this utility model, the telescopic hose, the second electric push rod, the sliding plate, and the second limiting rod work together. The second electric push rod pushes the sliding plate, causing the drill rod and drill bit to perform high-frequency reciprocating motion. The second limiting rod ensures the motion accuracy, enabling the drill bit to powerfully impact the rock to achieve breakage. At the same time, the servo motor drives the drill bit to rotate at high speed to cut the rock and form a circular drill hole. During this process, the water pump draws water from the water tank and sprays it out through the telescopic hose from the nozzle to cool the working surface, preventing the drill bit from being damaged by high temperature and extending the service life of the drill bit.

[0027] Please see Figures 1-5 This utility model provides a technical solution: an efficient auxiliary tool for tunnel excavation in rail transit, including an adjustment mechanism 1, with a moving mechanism 2 fixedly installed on the inner wall of the adjustment mechanism 1; the adjustment mechanism 1 includes a base plate 101, a rotating shaft 107 rotatably connected to the top of the base plate 101, a disc 102 fixedly connected to the top end face of the rotating shaft 107, a set of cylinders 124 fixedly connected to the inner wall of the disc 102, a set of insert rods 123 penetrating through the inner wall of the cylinders 124, and a set of pressure rods 123 sleeved on the outer wall of the insert rods 123.

A movable plate 111 is fixedly connected to the shaft end of the first electric push rod 109. A second electric push rod 112 is fixedly installed on the top of the movable plate 111. A sliding plate 118 is slidably connected to the inner wall of the movable plate 111. With the above components, the user can easily adjust the angle and height of the drill bit 120 according to actual needs, which is convenient for subsequent operations on rocks in different positions.

[0028] like Figure 2As shown, a set of movable rods 105 are slidably connected to the inner wall of the base plate 101. A PLC controller 106 is fixedly installed on the top of the base plate 101. The top of the movable rods 105 is fixedly connected to the bottom of the disc 102. The movable rods 105 enable the stability of the disc 102 during rotation. The PLC controller 106 is electrically connected to the components to control the opening and closing of the components.

[0029] like Figure 2 As shown, a first limiting rod 110 is fixedly connected to the top of the disc 102. The outer wall of the first limiting rod 110 is slidably connected to the inner wall of the movable plate 111. The stability of the movable plate 111 during its up-and-down movement is achieved by setting the first limiting rod 110.

[0030] like Figure 2 and Figure 4 As shown, the top of the base plate 101 is provided with a circular hole 108. The inner wall of the circular hole 108 is slidably connected to the outer wall of the insertion rod 123. One end of the compression spring 125 is fixedly connected to the inner wall of the cylinder 124, and the other end of the compression spring 125 is fixedly connected to the outer wall of the insertion rod 123. The circular hole 108 facilitates the insertion rod 123 to be inserted into a designated position so as to restrict the disc 102.

[0031] like Figure 2 As shown, a set of third electric push rods 103 are fixedly installed on the outer wall of the base plate 101. A set of anti-slip pads 104 are fixedly connected to the shaft end of the third electric push rods 103. By setting the third electric push rods 103 and anti-slip pads 104, the overall stability can be ensured and displacement can be avoided during operation.

[0032] like Figure 3 As shown, a set of second limiting rods 119 are fixedly connected to the inner wall of the movable plate 111. The outer wall of the second limiting rods 119 is slidably connected to the inner wall of the slide plate 118. The shaft end of the second electric push rod 112 is fixedly connected to the outer wall of the slide plate 118. By setting the second limiting rods 119, the stability of the slide plate 118 when sliding back and forth can be achieved, so that drilling and impact operations can be carried out normally.

[0033] like Figure 3As shown, a nozzle 122 is fixedly installed on the top of the slide plate 118, a water tank 113 is fixedly connected to the top of the movable plate 111, an inlet pipe 114 is fixedly connected to the top of the water tank 113, a sealing cap is movably inserted into the inner wall of the inlet pipe 114, a water pump 115 is fixedly connected to one side of the outer wall of the water tank 113, and a telescopic hose 116 is fixedly connected to the output end of the water pump 115. The telescopic hose 116 is connected to the inside of the nozzle 122. Through the nozzle 122, water tank 113, telescopic hose 116 and inlet pipe 114, water can be pressurized and sprayed into the borehole to cool the drill bit 120. The telescopic hose 116 also avoids interfering with the back-and-forth movement of the slide plate 118.

[0034] like Figure 3 As shown, a servo motor 117 is fixedly installed on the outer wall of the slide plate 118. A drill rod 121 is fixedly connected to the output end of the servo motor 117. A drill bit 120 is fixedly installed on the outer wall of the drill rod 121. The servo motor 117 can drive the drill rod 121 and the drill bit 120 to rotate, so that the drilling operation can proceed normally.

[0035] like Figure 5 As shown, the moving mechanism 2 includes a connecting column 201. A damper 202 is fixedly installed on the inner wall of the connecting column 201. A self-locking wheel 204 is fixedly connected to the shaft end of the damper 202. A spring 203 is sleeved on the outer wall of the connecting column 201. Through the damper 202 and the spring 203, the influence on the overall movement is effectively reduced.

[0036] The operating method and working principle of this device are as follows: Before rock drilling begins, the operator first moves the entire device to the designated location using the self-locking wheel 204. Upon arrival, the operator manually operates the brake block on the self-locking wheel 204 to make it tightly engage with the wheel, thereby locking the wheel and preventing the device from continuing to roll. Next, the operator activates the third electric push rod 103 via the control panel on the PLC controller 106, causing the anti-slip pad 104 to move downwards until it contacts the ground, thereby enhancing the stability of the device during operation. During operation, the operator again activates the control panel... The control panel starts the water pump 115, the second electric push rod 112, and the servo motor 117. The second electric push rod 112 pushes the slide plate 118 to slide back and forth on the second limit rod 119. The slide plate 118 drives the servo motor 117, the drill rod 121, and the drill bit 120 to reciprocate horizontally, so that the drill bit 120 powerfully impacts the rock to break it. At the same time, the servo motor 117 drives the drill rod 121 and the drill bit 120 to rotate, performing drilling operations on the rock. During the drilling process, the water pump 115 draws water from the water tank 113 and... Water is pumped into the telescopic hose 116 and transported to the nozzle 122, where it is sprayed into the borehole to cool the drill bit 120 and prevent it from being damaged by high temperature. If the angle of the drill bit 120 needs to be adjusted, the user pulls the pull plate 126 to lift the insertion rod 123 vertically upwards. When the insertion rod 123 is pulled to a certain position, it will disengage from the circular hole 108. At this point, the user can rotate the disc 102 via the rotating shaft 107. The rotation of the disc 102 will drive the first electric push rod 109 and the movable plate. 111 and the drill bit 120 rotate together, thereby adjusting the angle of the drill bit 120. After the angle adjustment is completed, the pull plate 126 is released, and the insertion rod 123 will be forcefully inserted into the corresponding round hole 108 under the elastic force of the compression spring 125, thereby restricting the disc 102 and ensuring that the drill bit 120 is stably at the specified angle. In addition, through the coordinated cooperation of the PLC controller 106, the first electric push rod 109 and the first limit rod 110, the height of the drill bit 120 and the movable plate 111 can also be adjusted to adapt to different operating requirements.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
