Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of tunnel construction technology. Specifically, it relates to a material supply pipe sorting frame for a drilling and blasting trolley. Background Technology

[0002] In hydraulic tunnel excavation, the drill-and-blast method is generally used. A drill-and-blast rig is used for excavation and initial support. Before excavation, blast holes are drilled, and during the initial support process, anchor bolt holes are drilled using hand-held pneumatic drills. When there are many hand-held pneumatic drills, there are many branch pipes from the main air and water supply pipes in the tunnel, which easily leads to hose entanglement and significant hose wear during drilling, affecting construction progress and safety, reducing construction efficiency, and increasing labor costs. Existing drill-and-blast rigs do not have transfer points in the air and water supply systems, resulting in pipe entanglement and time-consuming hose untangling during drilling. Therefore, a material supply pipe untangling rack for the drill-and-blast rig is designed. Utility Model Content

[0008] As a preferred embodiment of this utility model, both sides of the limiting cylinder are provided with arc-shaped recesses, and the surface of the fixing plate is provided with several adjustment holes.

[0009] As a preferred technical solution of this utility model, the fixed block has an internal groove for the rotating ball to move in, and a threaded post is fixed on the inner side of the limiting block. The threaded post passes through the fixed block and is threadedly engaged with the rotating ball.

[0010] As a preferred embodiment of this utility model, a connecting post is provided between the upper end of the rotating ball and the fixed plate.

[0028] like Figure 1-5As shown, this utility model provides a material feeding pipe sorting rack for a drilling and blasting trolley, including a limiting member 10. The limiting member 10 includes two fixing plates 101 and a limiting cylinder 102. The limiting cylinder 102 is disposed between the two fixing plates 101, and a connecting rod 103 is provided between the limiting cylinder 102 and the fixing plates 101.

[0029] Adjusting component 20 is located at the bottom of limiting component 10. Adjusting component 20 includes a fixing block 201, a rotating ball 202, a limiting block 203, and a mounting plate 206. The rotating ball 202 is located inside the fixing block 201, the limiting block 203 is located outside the fixing block 201, and the mounting plate 206 is located at the bottom of the fixing block 201. A support column 207 is provided between the mounting plate 206 and the fixing block 201.

[0030] The support column 207 is equipped with a shock absorber 30. The shock absorber 30 includes a movable cylinder 301, a piston rod 302, a spring 303, and an adjusting block 304. The movable cylinder 301 is sleeved on the outside of the piston rod 302. The spring 303 surrounds the outside of the movable cylinder 301 and the piston rod 302. The adjusting block 304 is disposed between the spring 303 and the movable cylinder 301.

[0031] Furthermore, in this embodiment, the connecting rod 103 passes through the limiting cylinder 102 and is threadedly engaged with the limiting cylinder 102, and its upper and lower ends are threadedly engaged with the fixing plate 101 respectively. The surface of the fixing plate 101 is provided with a fixing nut 104 that is threadedly engaged with the connecting rod 103. The limiting cylinder 102 is installed on the fixing plate 101 by the connecting rod 103, and the position of the connecting rod 103 on the fixing plate 101 is restricted by tightening the fixing nut 104.

[0032] In this embodiment, both sides of the limiting cylinder 102 are provided with arc-shaped recesses 106. The arc-shaped recesses 106 are designed to cooperate with the pipe 40, so that the pipe 40 can move inside the limiting cylinder 102. The surface of the arc-shaped recesses 106 is fixed with rubber to improve friction. The surface of the fixing plate 101 is provided with several adjustment holes 105. The position of the limiting cylinder 102 is adjusted according to the size of the pipe 40 through the adjustment holes 105 to adapt to the size of the pipe 40.

[0033] In this embodiment, the fixed block 201 has an internal movable groove 208 for the rotating ball 202 to move. The movable groove 208 facilitates the rotating ball 202 to rotate circumferentially within the fixed block 201. A threaded post is fixed to the inner side of the limiting block 203. The threaded post passes through the fixed block 201 and is threadedly engaged with the rotating ball 202. By rotating the limiting block 203, the threaded post is screwed into the fixed block and connected to the rotating ball 202, thus limiting the position of the rotating ball 202. This is achieved by pre-opening several threaded holes on the outer surface of the rotating ball 202 for engagement.

[0034] In this embodiment, a connecting post 204 is provided between the upper end of the rotating ball 202 and the fixed plate 101. The connecting post 204 is fixed to the upper end of the rotating ball 202 and is threadedly engaged with the fixed plate 101. A tightening member 205 is also threadedly engaged on the outer side of the connecting post 204. The tightening member 205 is located on the outer side of the connecting post 204 and is a ring design. The connecting post 204 is connected to the fixed plate 101 by threads, and the tightening member 205 abuts against the bottom of the fixed plate 101 to fix the connection between the connecting post 204 and the fixed plate 101.

[0035] In this embodiment, the upper end of the movable cylinder 301 is threadedly engaged with the fixed block 201, and the movable cylinder 301 directly receives the force from the fixed block 201. The movable cylinder 301 is a hollow cylindrical design. The bottom of the piston rod 302 is screwed to the mounting plate 206 and is mounted on the drilling and blasting trolley through the mounting plate 206. The two ends of the spring 303 are fixedly connected to the adjusting block 304 and the bottom of the piston rod 302, respectively.

[0036] In this embodiment, the adjusting block 304 is threadedly engaged with the movable cylinder 301. By adjusting the position of the adjusting block 304, the extension length of the spring 303 connected to it is adjusted, thereby adjusting the damping capacity of the spring 303 so that it can adapt to the force from the air or water supply pipe 40 during material feeding and maintain the stability of the entire frame. A damping block 305 is threadedly engaged near the bottom of the piston rod 302. The damping block 305 is located below the movable cylinder 301 and limits the range of motion of the movable cylinder 301.

[0037] Specifically, during the installation phase, the mounting plate 206 is first installed on the drilling and blasting trolley. The mounting plate 206 is then tightly connected to the drilling and blasting trolley with screws to ensure the fixation of the entire device. The support column 207 is equipped with a shock absorber 30, and its bottom is connected to the mounting plate 206 with screws to provide stable support for the entire pipe arrangement frame. The limiting cylinder 102 is placed between the two fixing plates 101. The connecting rod 103 passes through the limiting cylinder 102 and is threadedly engaged with the limiting cylinder 102. A fixing nut 104 is provided on the surface of the fixing plate 101 to thread with the connecting rod 103. The position of the connecting rod 103 is fixed by tightening the fixing nut 104, so that the limiting cylinder 102 is tightly connected to the fixing plate 101.

[0038] During the placement and adjustment of the pipe 40, the position of the limiting cylinder 102 is adjusted using the adjustment hole 105 on the fixing plate 101 according to the size and direction of the pipe 40. After loosening the fixing nut 104 and moving the limiting cylinder 102 to a suitable position, the fixing nut 104 is tightened to make the limiting cylinder 102 fit tightly with the pipe 40. The pipe 40 is placed in the arc-shaped recess 106 of the limiting cylinder 102. The rubber on the arc-shaped recess 106 increases the friction to prevent the pipe 40 from sliding or shaking during operation. By adjusting the position and angle of the limiting cylinder 102, it is ensured that the pipe 40 is stably placed in the limiting cylinder 102.

[0039] During the shock absorption phase, when the air or water supply pipe 40 generates force during material supply, the shock absorber 30 inside the support column 207 starts to work. The movable cylinder 301 receives the force from the fixed block 201 and moves up and down on the outer surface of the piston rod 302. At the same time, the spring 303 absorbs shock by extension and contraction, and the damping block 305, which is threaded near the bottom of the piston rod 302, further enhances the shock absorption effect and prevents the movable cylinder 301 from moving excessively, which could lead to instability of the device.

[0040] During the angle adjustment stage, the connecting column 204 is fixed to the fixed plate 101 by the tightening part 205 abutting against the bottom of the fixed plate 101, thereby enhancing the stability of the entire device. The angle is adjusted by manually adjusting the rotating ball 202. Then, the limiting block 203 is rotated to screw the threaded column into the fixed block 201 and connect it to the rotating ball 202, thereby limiting the position of the rotating ball 202 and adjusting the angle of the limiting cylinder 102 to adapt to the direction of the pipeline 40.

[0041] The components of this utility model, such as the limiting component 10, fixing plate 101, limiting cylinder 102, connecting rod 103, fixing nut 104, adjusting component 20, fixing block 201, rotating ball 202, limiting block 203, connecting column 204, tightening component 205, mounting plate 206, support column 207, shock absorber 30, movable cylinder 301, piston rod 302, spring 303, adjusting block 304, damping block 305, and pipe 40, are all general standard parts or components known to those skilled in the art.
