Description

Technical Field

[0001] This utility model relates to the field of blasting materials, specifically a detonator arrangement structure for blasting in highway engineering. Background Technology

[0002] Smooth blasting is a blasting technique for controlling the excavation profile of rock masses. It involves a series of measures to correctly drill and blast the surrounding areas of the excavation project, with the peripheral holes being the last to detonate. In smooth blasting of tunnels, detonators need to be installed in the blast holes. The volume of the blast holes is generally too large for the detonators, making it inconvenient to adjust their installation positions. Moreover, to ensure the stability of the detonator installation, cement needs to be filled into the blast holes for fixation. This construction method has a long construction period and cannot meet current development needs.

[0003] To address the aforementioned issues, a search revealed Chinese patent CN217818400U, which discloses a detonator fixing device for smooth blasting in highway tunnels. The device includes an outer tube body, a detonator placement sleeve, and a support structure. The outer tube body has two symmetrical support structures on its left and right sides, and two symmetrical guide posts are fixed to the front and rear ends of the inner wall of the outer tube body. Each guide post has a sliding ear plate connected to its side, and the inner side of the ear plate is welded with the detonator placement sleeve. Although the above-mentioned device can be easily installed in blast holes of different diameters by rotating the screw 42 to adjust the distance between the roller 45 and the outer tube 1, in actual use, the detonator hole is generally circular. Adjusting the position of the rollers one by one by rotating the screw 42 cannot quickly adjust the positions of multiple sets of rollers to be consistent, nor can it quickly adapt to the inner diameter of the blast hole. Utility Model Content

[0004] The purpose of this utility model is to provide a detonator arrangement structure for blasting in highway engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a detonator arrangement structure for blasting in highway engineering is provided, including an arrangement vehicle. The arrangement vehicle has a clamping tube inside, and a detonator is inserted inside the clamping tube. The arrangement vehicle has an adaptive adjustment wheel set inside, and a wheel set A and a wheel set B are respectively installed on the adaptive adjustment wheel set. The adaptive adjustment wheel set includes a screw inserted inside the arrangement vehicle, and an adjustment handwheel is fixed at the end of the screw.

[0006] Furthermore, the arrangement vehicle is a hollow triangular prism, and a core seat is provided in the middle of the arrangement vehicle. Two sets of screws are provided, and the two sets of screws are connected by a main shaft. At the same time, the main shaft is inserted into the core seat through a bearing.

[0007] Furthermore, the core base is triangular prism-shaped, and three sets of wheels A and wheels B are respectively installed on both sides of the core base. At the same time, the core base is installed in the arrangement vehicle through a T-shaped frame.

[0008] Furthermore, both sets of screws are screwed with adjusting seats, and the adjusting seats have a triangular cross-section, with support arms connected to each of the three surfaces of the adjusting seats.

[0009] Furthermore, the adjusting seat has three sets of guide holes equidistantly spaced, and guide rods are inserted into the interior of each of the three sets of guide holes. One end of the guide rod is fixed to the core seat, and the other end is fixed to a fixing seat. At the same time, the end of the fixing seat is fixed to the inner wall of the vehicle.

[0010] Furthermore, the wheel assembly A and wheel assembly B have the same structure. Wheel assembly A includes a support frame, a support arm and a wheel body, with the end of the support frame movably connected to the core seat and the other end of the support frame movably mounted with a wheel body.

[0011] Furthermore, the support frame is internally connected to a support arm, and the support arm and the support frame are arranged in a herringbone shape.

[0012] Furthermore, a rubber sleeve is inserted inside the clamping tube, and multiple sets of clamping strips are equidistantly arranged on the inner side of the rubber sleeve. The detonator is fixedly inserted inside the clamping tube by the rubber sleeve and clamping strips.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution adjusts the position of multiple sets of wheels by simply rotating the adjustment handwheel. There is no need to assemble or adjust the wheels one by one. The rotation of a single adjustment handwheel can drive multiple sets of wheels to extend and retract synchronously, reducing manual operation steps, lowering the technical threshold for operators, improving adjustment efficiency, avoiding the tedious process of adjusting multiple parts separately, quickly adapting to blasting holes of different diameters, shortening device preparation time, and improving the overall progress of blasting operations. 2. This solution uses the flexible material of the rubber sleeve to avoid hard contact between the detonator and the clamping tube, reducing friction and impact damage during insertion, removal and transportation. Its own elasticity can adapt to the shape tolerance of the detonator. With the multiple sets of clamping strips set at equal intervals on the inner side, it can form a uniform and tight clamping force on the detonator from the circumference, which can ensure the stability of the detonator in the clamping tube.

Detailed Implementation

[0016] Please see Figure 1-6 This utility model provides a detonator arrangement structure for blasting in highway engineering, including an arrangement vehicle 100. The arrangement vehicle 100 is equipped with a clamping tube 200, and a detonator 300 is inserted inside the clamping tube 200. The arrangement vehicle 100 is equipped with an adaptive adjustment wheel set 400, and a wheel set A45 and a wheel set B46 are respectively installed on the adaptive adjustment wheel set 400. The adaptive adjustment wheel set 400 includes a screw 42 inserted inside the arrangement vehicle 100, and an adjustment handwheel 41 is fixed at the end of the screw 42.

[0017] In a preferred embodiment, the arrangement vehicle 100 is a hollow triangular prism, and a core seat 44 is provided in the middle of the arrangement vehicle 100. Two sets of screws 42 are provided, and the two sets of screws 42 are connected by a main shaft. At the same time, the main shaft is inserted into the core seat 44 through a bearing.

[0018] The core base 44 is triangular prism in shape, and three sets of wheels A45 and wheels B46 are installed on both sides of the core base 44 respectively. At the same time, the core base 44 is installed in the arrangement vehicle 100 through a T-shaped frame.

[0019] Both sets of screws 42 are screwed with adjusting seats 43, and the cross-section of the adjusting seats 43 is triangular. Support arms 452 are connected to the three sides of the adjusting seats 43.

[0020] Three sets of guide holes are equally spaced on the adjusting seat 43, and guide rods 431 are inserted into the interior of each of the three sets of guide holes. One end of the guide rod 431 is fixed to the core seat 44, and the other end is fixed to the fixing seat 432. At the same time, the end of the fixing seat 432 is fixed to the inner wall of the arrangement vehicle 100.

[0021] The wheel assembly A45 and the wheel assembly B46 have the same structure. The wheel assembly A45 includes a support frame 451, a support arm 452 and a wheel body 453. The end of the support frame 451 is movably connected to the core seat 44, and the other end of the support frame 451 is movably mounted with the wheel body 453.

[0022] The support frame 451 is internally connected to a support arm 452, and the support arm 452 and the support frame 451 are arranged in a herringbone shape.

[0023] Working principle: In use, the detonator 300 is inserted into the clamping tube 200 inside the arrangement vehicle 100. By rotating the adjusting handwheel 41 of the adaptive adjusting wheel set 400, the two sets of screws 42 are driven to rotate synchronously. Since the two sets of screws 42 are connected by a main shaft, and the main shaft is inserted into the triangular prism-shaped core seat 44 in the middle of the arrangement vehicle 100 via bearings, the rotation of the screws 42 will drive the adjusting seat 43 screwed to it to move linearly along the guide rod 431. When the adjusting seat 43 moves, it will drive the three sets of screws 42 to rotate. The support arm 452 connected to one side moves, while the other end of the support arm 452 is movably connected to the inside of the support frame 451 of the wheel assembly A45 and the wheel assembly B46. The support arm 452 and the support frame 451 are distributed in a V-shape. The angle of the support frame 451 can be adjusted by pushing and pulling the support arm 452, which ultimately drives the wheel body 453 to extend and retract to adapt to blasting holes of different diameters. Then, the placement vehicle 100 loaded with detonators 300 is sent into the blasting hole to complete the placement of detonators 300. Through the structural design of the adaptive adjustable wheel set 400, the wheel body 453 can be flexibly extended and retracted, enabling the placement vehicle 100 to adapt to blasting holes of different diameters, thus improving the versatility of the device. At the same time, the guide rod 431 ensures that the adjustment seat 43 moves smoothly, and the herringbone-shaped support arms 452 and support frame 451 enhance the support stability of the wheel set A45 and wheel set B46, ensuring that the detonator 300 is in a stable position during transportation and placement, thereby improving the safety and reliability of blasting operations.

[0024] The position adjustment of multiple sets of wheels 453 can be achieved simply by rotating the adjusting handwheel 41. There is no need to assemble or adjust each wheel 453 individually. The rotation of a single adjusting handwheel 41 can drive multiple sets of wheels 453 to extend and retract synchronously, reducing manual operation steps and lowering the technical threshold for operators. It improves adjustment efficiency, avoids the tedious process of adjusting multiple components separately, quickly adapts to blasting holes of different diameters, shortens device preparation time, and improves the overall progress of blasting operations. Multiple sets of wheels 453 are linked by components such as screw 42 and adjusting seat 43. When rotating the adjusting handwheel 41, the extension and retraction of each wheel 453 can be consistent, ensuring that the placement vehicle 100 is subjected to balanced force and runs smoothly in the blasting hole, further ensuring the accuracy and safety of the detonator 300 placement.

[0025] In a preferred embodiment, a rubber sleeve 201 is inserted inside the clamping tube 200, and multiple sets of clamping strips 202 are provided at equal intervals on the inner side of the rubber sleeve 201. The detonator 300 is fixedly inserted inside the clamping tube 200 through the rubber sleeve 201 and the clamping strips 202.

[0026] like Figure 6 As shown: The flexible material of the rubber sleeve 201 can prevent the detonator 300 from making hard contact with the clamp tube 200, reducing friction and impact damage during insertion, removal and transportation. Its own elasticity can adapt to the shape tolerance of the detonator 300. With the multiple sets of clamping strips 202 arranged at equal intervals on the inner side, it can form a uniform and tight clamping force on the detonator 300 from the circumference. This ensures the fixed stability of the detonator 300 in the clamp tube 200 and prevents loosening or positional deviation when the placement vehicle 100 moves or is adjusted. At the same time, because the clamping strips 202 reduce the contact area with the detonator 300, it avoids damage caused by excessive local pressure. When the deployment vehicle 100 moves inside the blasting hole, it can be pushed using an extension pole. The deployment vehicle 100 can be made of relatively inexpensive plastic material, making it inexpensive and suitable for use as a disposable device in large-scale highway construction projects.
