Description

Technical Field

[0001] This utility model relates to the field of auxiliary loading of emulsion explosives, specifically to a tube-pulling mechanism after loading emulsion explosives. Background Technology

[0002] Currently, deep-hole loading of emulsion explosives requires auxiliary loading via a pipe. During loading, the pipe is first inserted into the bottom of the deep hole, and then the emulsion explosive is loaded through the pipe. This process involves loading and simultaneously pulling out the pipe to ensure the bottom of the deep hole is filled with emulsion explosive, thus guaranteeing the blasting effect. To reduce wear from pulling out the auxiliary pipe, a pipe-pulling mechanism is installed at the top of the deep hole. This mechanism primarily uses pulleys to change the direction of the pipe, ensuring it remains vertically upright during extraction and preventing wear. However, the current roller method has significant drawbacks. The current pipe-pulling mechanism still relies on manual extraction, which is more forceful and lacks a one-way extraction mechanism (when the operator releases the pipe), allowing it to easily move in the opposite direction and pierce the emulsion explosive within the deep hole. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes a tube-pulling mechanism after emulsion explosive is loaded, which can perform automatic and manual tube pulling, achieve unidirectional tube pulling, and align the tube-pulling mechanism with the deep hole.

[0004] To achieve the above objectives, the present invention provides a pipe-pulling mechanism for emulsion explosives after loading, comprising a mounting frame, a swing adjustment component, a roller, and a clamping mechanism. The mounting frame is hinged to the rear of a transport vehicle, and the swing adjustment component is provided at both the mounting frame and the rear of the transport vehicle. A roller is mounted on the end of the mounting frame away from the transport vehicle, and the roller is unidirectionally rotatably connected to the mounting frame. Two sets of clamping mechanisms that move on the roller are fitted onto the roller, thereby clamping both sides of the pipe.

[0005] Preferably, the clamping mechanism includes a sliding ring, clamping wheels, locking bolts, and a swing rod. The sliding ring is fitted onto the roller and rotates relative to the roller. The clamping wheel is installed inside the sliding block and presses against the side and top of the pipe. A guide rod is fixed outside the sliding ring, passes through the mounting frame, and slides on the mounting frame. A spring is fitted onto the guide rod. A locking bolt is inserted into the mounting frame and presses against the guide rod. The two clamping wheels are combined to form a pulley.

[0006] Preferably, a motor is installed on the mounting brackets at both ends of the roller, and a rotating cover is fixed to the output shaft of the motor. Both ends of the roller extend into the rotating cover. A helical gear is fixed in one end of the roller that extends into the rotating cover. Multiple pawls are installed in the rotating cover. The pawls mesh with the helical gear. When the motor is working, the rotating cover and the roller rotate synchronously. When the motor is locked, the roller can rotate in one direction.

[0007] Preferably, the mounting frame is a U-shaped frame, with both ends of the roller fixed on the mounting frame, and the mounting frame is hinged to the transport vehicle; the swing adjustment component is a hydraulic cylinder, and a hydraulic cylinder is hinged between the rear of the transport vehicle and the swing frame.

[0008] Preferably, a one-way bearing is provided between the clamping wheel and the swing rod.

[0009] Compared with the prior art, the advantages of this utility model are: it can perform automatic and manual tube pulling, achieve unidirectional tube pulling, and align the tube pulling mechanism with the deep hole. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] like Figure 1-4As shown, a tube-pulling mechanism for emulsion explosives after loading includes a mounting frame 1, a swing adjustment component 2, a roller 4, and a clamping mechanism 8. The mounting frame 1 is hinged to the rear of a transport vehicle (which is a vehicle for mixing the aqueous and oil phases of the emulsion explosive, and the mixed aqueous and oil phases are then filled). The swing adjustment component 2 is located at both the mounting frame 1 and the rear of the transport vehicle, allowing adjustment of the angle of the mounting frame 1. A roller 4 is mounted on the end of the mounting frame 1 away from the transport vehicle via a bearing. The outer wall of the roller 4 is covered with an anti-slip pad. The roller 4 is unidirectionally rotatably connected to the mounting frame 1, thus enabling unidirectional rotation of the roller 4. Two sets of movable components are fitted onto the roller 4. The clamping mechanism 8 consists of two sets of clamping mechanisms 8 arranged on the left and right sides. The clamping mechanism 8 clamps the pipe on both sides. The pipe is placed on the roller 4, and the two sets of clamping mechanisms 8 clamp the pipe on both sides. The pipe is pulled out by the rotation of the roller 4 (the pipe is a steel wire hose). It will not deform under pressure. Since the roller 4 is unidirectionally connected to the mounting frame 1, the roller 4 can only rotate clockwise and cannot rotate counterclockwise. This prevents the pipe from sliding in the opposite direction when pulling out the pipe, so the pipe will not extend into the deep hole. When the pipe is pulled out manually (the pulling speed is relatively slow), the operator releases the pipe and the pipe will not slide in the opposite direction, thus preventing the pipe from extending into the emulsion explosive.

[0017] The clamping mechanism 8 includes a sliding ring 9, a clamping wheel 10, a locking bolt 11, and a swing rod 12. The sliding ring 9 is fitted onto the roller 4 and moves left and right on the roller 4. The sliding ring 9 rotates relative to the roller 4 (i.e., the roller 4 rotates, but the sliding ring 9 does not). The clamping wheel 10 is installed inside the sliding block and presses against the side and top of the pipe. Two guide rods 13 are fixed to the outside of the sliding ring 9 by welding. The guide rods 13 pass through the mounting frame 1 and slide on the mounting frame 1, thus adjusting the distance between the two sliding rings 9. A spring is fitted onto the guide rod 13, and a locking bolt 11 is inserted into the mounting bracket 1. The locking bolt 11 presses against the guide rod 13. When the locking bolt 11 is tightened, the guide rod 13 cannot slide, thus locking the position of the sliding ring 9. When the position of the sliding ring 9 needs to be adjusted, the locking bolt 11 is loosened, and the sliding rings 9 move closer together under the action of the spring. When the inner wall of the sliding ring 9 contacts the clamping wheel 10 and the outer wall of the pipe, the sliding ring 9 stops moving. Then, the locking bolt 11 is tightened to lock it. The two clamping wheels 10 merge to form a pulley with a semi-circular annular groove in the middle.

[0018] Motors are mounted on mounting brackets 1 at both ends of roller 4 by bolts. The output shaft of the motor is fixed to a rotating cover 5 by welding. Both ends of roller 4 extend into the rotating cover 5. A helical gear 6 is fixed to one end of roller 4 that extends into the rotating cover 5 by welding. Multiple pawls 7 are mounted inside the rotating cover 5 by hinge. A spring is fixed between the pawls 7 and the outer wall of the rotating cover 5 by welding. The spring pushes the pawls 7 inward to contact the outer wall of the helical gear 6. The pawls 7 and the helical gear 6 mesh. When the motor is working, the rotating cover 5 and roller 4 rotate synchronously (clockwise). When the motor is locked, roller 4 can rotate in one direction (clockwise).

[0019] Mounting frame 1 is a U-shaped frame. Both ends of roller 4 are mounted on mounting frame 1 via bearings. The end of mounting frame 1 away from roller 4 is hinged to the transport vehicle. The swing adjustment component 2 is a hydraulic cylinder 3. The hydraulic cylinder 3 is connected to the vehicle's hydraulic system via a pipe. The rear of the transport vehicle is hinged to the swing mounting frame 1. The tilt of mounting frame 1 is adjusted by the hydraulic cylinder 3 to make the vertical tangent of the outer circumference of roller 4 opposite to the edge of the deep hole. That is, the pipe is wrapped around roller 4, and one end of the pipe is vertically downward under the action of gravity. The pipe is coaxial with the deep hole.

[0020] A one-way bearing 14 is fixed between the clamping wheel 10 and the swing rod 12 by welding, so that the clamping wheel 10 can rotate counterclockwise and prevent the pipe from sliding backward and downward into the deep hole.
