Description

Technical Field

[0001] This utility model belongs to the field of tunnel blasting technology, specifically a rapid filling device for tunnel blasting blast holes. Background Technology

[0002] Tunnel blasting is a crucial step in tunnel construction. Its purpose is to break rocks by controlling the explosive energy of explosives, thereby enabling tunnel excavation. Hole packing is a vital step in tunnel blasting, and its quality directly affects the blasting effect and construction safety. In tunnel blasting operations, by controlling the explosive energy, the rock around the tunnel outline is broken according to design requirements, thus forming a tunnel space that meets design standards. After loading the explosives, the blast holes need to be packed. The enormous impact force and flying debris generated during blasting pose a threat to the surrounding environment and the safety of construction personnel. Therefore, blasting... Hole packing is a crucial step in controlling blasting effects and ensuring safety. The purpose of packing is to prevent explosive energy from dissipating in the blast holes and to ensure that the explosive energy can be effectively transferred to the rock, thereby improving the blasting effect. In tunnel blasting operations, hole packing mainly relies on manual operation, and the packing materials used are usually rock powder or stemming mud. Manual packing is inefficient, especially in large tunnel projects where there are many blast holes and they are widely distributed. Manual packing requires a lot of time and manpower. With the continuous development of tunnel construction technology, higher requirements have been placed on the efficiency and safety of blast hole packing.

[0003] The existing rapid filling devices for tunnel blasting holes have the following main shortcomings:

[0004] Existing rapid filling devices for tunnel blasting boreholes lack specific measures for handling materials entering the filling stage. If large pieces of material are present, the filling operation may be performed directly, easily leading to blockage and affecting filling efficiency and quality. When using simple tools to transport materials such as stone powder, large pieces may mix in, directly blocking the passage when the borehole is small. Manual filling is usually required, which is inefficient and labor-intensive. Even with some simple tools, there is a lack of effective power supply. Manually stuffing the blasting mud into the borehole piece by piece is slow and makes it difficult to ensure the continuity and uniformity of the filling process. Furthermore, the length cannot be adjusted for blocking, making it difficult to adapt to borehole filling operations under different working conditions. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a rapid filling device for tunnel blasting boreholes, which solves the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid filling device for tunnel blasting boreholes, comprising: a filling pipe, an inner tube sleeved on one side of the center of the inner wall of the filling pipe, a filling structure on one side of the center of the upper end face of the filling pipe, an anti-blocking conveying structure at the center of the side wall of the filling pipe, and adjustment structures on both the inner wall of the filling pipe and the outer wall of the inner tube;

[0007] The packing structure includes a packing hopper, which is located at the center of the upper end face of the packing pipe on one side. An installation plate is provided at the upper center of one side wall of the packing hopper. A first servo motor is provided at the center of one side wall of the installation plate. The output end of the first servo motor passes through one side wall of the installation plate and one side wall of the packing hopper in sequence and leads to the interior of the packing hopper. A spiral crushing rod is fixedly connected to the end of the motor.

[0008] As a further embodiment of this utility model: the anti-blocking conveying structure includes a second servo motor, which is located at the center of one side wall of the filling pipe. The output end of the second servo motor passes through one side wall of the filling pipe and extends into the interior of the filling pipe, and a spiral conveying rod is fixedly connected to its end.

[0009] As a further embodiment of this utility model: the two adjustment structures include two sliding grooves, which are respectively located at the center of the upper inner wall and the lower inner wall of the filling pipe. Multiple limiting grooves are arranged laterally at one side of the center of the upper end face and one side of the center of the lower end face of the filling pipe. A slider is provided at one side of the center of the upper end face and one side of the center of the lower end face of the inner pipe. A limiting bolt is provided at the center of the upper end face of the limiting groove on one side near the top and the limiting groove on one side near the bottom.

[0010] As a further embodiment of this utility model: the two sliders are slidably connected inside the two grooves respectively.

[0011] As a further embodiment of this utility model, the two limiting bolts are respectively adapted to each other with the multiple limiting grooves.

[0012] As a further aspect of this utility model: the filling pipe and the inner pipe are mutually compatible.

[0013] As a further embodiment of this utility model, both the filling pipe and the inner pipe are made of stainless steel.

[0014] As a further embodiment of this utility model, the filling pipe is inclined.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses a first servo motor to drive a spiral crusher to crush large pieces of material, ensuring that the material enters the packing pipe smoothly. A second servo motor drives a spiral conveyor to rotate, which, together with the inclined packing pipe, effectively pushes the material toward the borehole, improving the efficiency and stability of the packing operation.

[0017] This invention changes the relative position of the inner tube and the filling pipe by sliding the slider in the groove and fixing it with a limit bolt, so that the whole device can better adapt to the filling operation of the blast hole under different working conditions, greatly improving the applicability and flexibility of the device.

Detailed Implementation

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution:

[0025] A rapid filling device for tunnel blasting boreholes includes: a filling pipe 1, an inner tube 2 sleeved on one side of the center of the inner wall of the filling pipe 1, a filling structure 3 on one side of the center of the upper end face of the filling pipe 1, an anti-blocking conveying structure 4 at the center of the side wall of the filling pipe 1, and adjustment structures 5 on both the inner wall of the filling pipe 1 and the outer wall of the inner tube 2. The filling pipe 1 and the inner tube 2 are mutually compatible. Both the filling pipe 1 and the inner tube 2 are made of stainless steel, and the filling pipe 1 is inclined.

[0026] The packing structure 3 includes a packing hopper 301, which is located at the center of the upper end face of the packing pipe 1. A mounting plate 302 is located at the upper center of one side wall of the packing hopper 301. A first servo motor 303 is located at the center of one side wall of the mounting plate 302. The output end of the first servo motor 303 passes through the side wall of the mounting plate 302 and the side wall of the packing hopper 301 and enters the inside of the packing hopper 301. A spiral crushing rod 304 is fixedly connected to the end of the spiral crushing rod 304. The packing hopper 301 conveys the packing material. The first servo motor 303 drives the spiral crushing rod 304 to rotate, crushing large pieces of material to prevent the material particles from being too large and affecting the subsequent packing process, and ensuring that the material can smoothly enter the packing pipe 1.

[0027] The anti-blocking conveying structure 4 includes a second servo motor 401, which is located at the center of one side wall of the filling pipe 1. The output end of the second servo motor 401 passes through one side wall of the filling pipe 1 and extends into the filling pipe 1. A spiral conveying rod 402 is fixedly connected to the end of the output end. When conveying materials, the second servo motor 401 is started to drive the spiral conveying rod 402 to rotate. The rotation of the spiral conveying rod 402 can push the filling hopper 301 into the filling pipe 1 and continuously move it towards the borehole. Since the filling pipe 1 is inclined, the spiral conveying rod 402 facilitates the sliding of materials.

[0028] The two adjustment structures 5 include two sliding grooves 501, which are respectively located at the center of the upper and lower inner walls of the filling pipe 1. Multiple limiting grooves 502 are arranged laterally on one side of the center of the upper end face and one side of the center of the lower end face of the filling pipe 1. Slider blocks 503 are provided on one side of the center of the upper end face and one side of the center of the lower end face of the inner pipe 2. Limiting bolts 504 are provided at the center of the upper end face of both the upper and lower limiting grooves 502. The two sliders 503 are slidably connected within the two sliding grooves 501. The device consists of two limiting bolts 504 that are mutually adapted to multiple limiting grooves 502. The position of the inner tube 2 can be adjusted according to the specific requirements of the blast hole. The slider 503 slides in the groove 501 of the filling pipe 1, thereby changing the relative position between the inner tube 2 and the filling pipe 1. Then, the limiting bolts 504 are fixed in the corresponding limiting grooves 502 of the inner tube 2 to determine the adjusted position. This allows the entire filling device to better adapt to blast hole filling operations under different working conditions, greatly improving the applicability and flexibility of the device.

[0029] The working principle of this utility model is as follows:

[0030] By adjusting the position of the inner tube 2 according to the specific requirements of the blast hole, and by having the slider 503 slide within the groove 501 of the filling pipe 1, the relative position between the inner tube 2 and the filling pipe 1 is changed. Then, a limiting bolt 504 is used to fix the inner tube 2 in the corresponding limiting groove 502 to confirm the adjusted position. This allows the entire filling device to better adapt to blast hole filling operations under different working conditions, greatly improving the applicability and flexibility of the device. After the length of the filling pipe 1 is adjusted, the filling material is conveyed through the filling hopper 301. The first servo motor 303 drives the spiral crusher 304 to rotate, crushing large pieces of material and preventing excessive particle size. The material has a significant impact on the subsequent filling process, ensuring that the material can smoothly enter the filling pipe 1. When conveying the material, the second servo motor 401 is started to drive the screw conveyor 402 to rotate. The rotation of the screw conveyor 402 can push the filling hopper 301 into the filling pipe 1 and continuously move it towards the blast hole. This can effectively push the material towards the blast hole, improving the efficiency and stability of the filling operation. The filling pipe 1 is inclined, which, together with the screw conveyor 402, facilitates the sliding of the material. The material pushed by the screw conveyor 402 continues to advance in the channel formed by the filling pipe 1 and the inner pipe 2 until it reaches the blast hole position, realizing the rapid filling operation of the tunnel blasting blast hole.

[0031] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
