Description

Technical Field

[0001] This utility model belongs to the field of explosives conveying technology, specifically relating to an explosives conveyor for deep-hole blasting operations. Background Technology

[0002] Traditional deep-hole blasting explosive conveyors in coal mining are mainly used in modern coal mining to transport explosives during targeted blasting in the mine area. These conveyors are typically pipe structures, allowing the explosive charges to move stably within the pipes and increasing the safety of the equipment. With the development of modern technology, the functions and structures of these devices have gradually improved, enabling them to better meet the needs of blasting operations.

[0003] A search revealed a Chinese utility model patent application (CN217686895U) disclosing a deep-hole blasting explosive conveyor for coal mines. The device includes a conveying base with a support frame fitted into its inner wall. Buffer springs are fixed at the midpoint of both sides of the inner wall of the support frame, and arc-shaped clamps are fixed to one end of each buffer spring. Rotating the inner wall of the base rotates limiting strips. Rotating the limiting strips causes them to compress one of the arc-shaped clamps, allowing the two arc-shaped clamps to hold the explosive charge under the action of the buffer springs. When the support frame descends to its lowest point under the action of a screw, pulling the rope causes the limiting strips to rotate and disengage from the arc-shaped clamps. The buffer springs then contract, releasing the explosive charge from the arc-shaped clamps. Finally, rotating the screw raises the support structure to detonate the explosive.

[0004] Regarding the aforementioned technologies, conventional conveyors place explosives in pipes and allow them to slide down. This operation results in a strong impact on the explosives upon landing due to gravity, which can easily cause an explosion or damage to the internal materials of the explosives, thereby reducing the safety of the device. Therefore, there is an urgent need to design a deep-hole blasting explosive conveyor to address these issues. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. The terms "first", "second", and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Reference Figure 1-6 One embodiment of this utility model is a deep-hole blasting explosive conveyor, which includes a base 1, a bearing mechanism 2 above the base 1, and a conveying execution mechanism 3 above the bearing mechanism 2.

[0027] In this embodiment: the supporting mechanism 2 includes a lifting hydraulic assembly fixedly mounted above the base 1. A hydraulic cylinder 201 is fixedly mounted on the lifting hydraulic assembly, and a pressure gauge 202 is fixedly mounted above the hydraulic cylinder 201. A lifting platform 205 is fixedly mounted on the lifting hydraulic assembly, and a first rotating rod 207 is rotatably mounted longitudinally on the lifting platform 205. A second rotating rod 208 is rotatably mounted parallel to one side of the first rotating rod 207, and a first electric lifting rod 206 is fixedly mounted on the second rotating rod 208. The lifting hydraulic assembly includes a lifting hydraulic cylinder 203 mounted above the base 1, and a lifting telescopic rod 204 is movably mounted on the lifting hydraulic cylinder 203. Connecting hydraulic pipes 209 are fixedly installed between the lifting hydraulic cylinders 203. A synchronization valve is installed on the lifting hydraulic cylinder 203. To enable the four lifting hydraulic cylinders 203 to start simultaneously, synchronization is achieved by adding a synchronization valve to the oil pipeline. The synchronization valve can control the flow rate and pressure of the oil, thereby enabling the hydraulic cylinders connected to it to move synchronously. When using a synchronization valve, it is necessary to pay attention to the consistency of the oil pipe length and bending radius to ensure synchronization. The pitch angle of the conveying actuator 3 is adjusted by the first electric lifting rod 206 so that the direction of conveying the casing 315 by the conveying actuator 3 can be adapted to the tilt angle of the deep hole, ensuring that the casing 315 can be conveyed at an angle parallel to the deep hole, and avoiding the problem of the casing 315 being subject to greater resistance during the conveying process.

[0028] In this embodiment: the conveying actuator 3 includes a movable lifting assembly that is lifted and lowered above the bearing mechanism 2. A longitudinal rotating shaft 303 is rotatably mounted on the upper part of the movable lifting assembly. A drive motor 304 is fixedly mounted at one end of the longitudinal rotating shaft 303. A conveyor belt 305 is rotatably mounted on the outer surface of the longitudinal rotating shaft 303. Support frames 306 are equidistantly fixedly mounted on the conveyor belt 305. A connecting shaft 307 is fixedly mounted on the support frame 306. A carrier wheel 308 is fixedly mounted on the outer surface of the connecting shaft 307. A manual double-ended lead screw 309 is rotatably mounted on the carrier wheel 308. A manual double-ended lead screw 309 is fixedly mounted on one side. A guide shaft 3091 is provided, and a circular platform 310 is fixedly mounted on the outer surface of the connecting shaft 307. A U-shaped moving platform 3101 is circumferentially movable on the circular platform 310. A rotating lower conveyor wheel 311 is fixedly mounted between a manual double-headed screw 309 and the U-shaped moving platform 3101. The rotating lower conveyor wheel 311 consists of two symmetrical half-wheels. An L-shaped frame 312 is fixedly mounted on the movable lifting assembly. A lifting installation assembly is fixedly mounted on the L-shaped frame 312. A rotating upper conveyor wheel 314 is rotatably mounted on the lifting installation assembly. A movable cylinder 315 is provided between the rotating lower conveyor wheel 311 and the rotating upper conveyor wheel 314. The movable lifting assembly includes a movable lifting platform 301 set above the bearing mechanism 2, and a groove 302 is fixedly set on the movable lifting platform 301. The lifting installation assembly includes a second electric lifting rod 313 set above the L-shaped frame 312. A mounting platform 3131 is fixedly mounted on the power telescopic end of the second electric lifting rod 313. Rotary support cylinders are fixedly installed at both ends of the mobile lifting platform 301. These rotating support cylinders support the loaded cylinder 315. The rotating support cylinders provide support and guidance for the loaded cylinder 315, preventing premature contact between the loaded cylinder 315 and the edge of the mobile lifting platform 301, which would increase resistance. They also provide rolling friction at both ends of the rotating support cylinder, reducing resistance during transport and improving efficiency. A movable limit rod is provided on one side of the rotating support cylinder. This limit rod prevents the loaded cylinder 315, being transported into the deep hole, from detaching from the rotating lower conveyor wheel 311 during transport, ensuring smooth loading. A groove is formed on the outer circumference of the circular platform 310, and the U-shaped mobile platform 3101 slides within this groove. The manual double-ended lead screw 309 is connected to the rotating lower conveyor wheel 311 by a thread, and the U-shaped moving table 3101 is fixedly connected to the rotating lower conveyor wheel 311.

[0029] Working principle: In use, explosives are first filled into the tube 315. A manual double-ended screw 309, via a threaded connection, drives the U-shaped moving table 3101 and the rotating lower conveyor wheel 311 to move relative to or towards each other. When the tube 315 is placed on the rotating lower conveyor wheel 311, the lower conveyor wheel 311 moves longitudinally and laterally according to the diameter of the tube 315 to adjust and clamp it. The drive motor 304 is then started, driving the longitudinal rotating shaft 303 to rotate, which in turn drives the conveyor belt 305 and the carrier wheel 308. The lower conveyor wheel 311 and the quilted cylinder 315 are moved by rotating the lower conveyor wheel 311. At the same time, the second electric lifting rod 313 is activated to push the mounting platform 3131 and rotate the upper conveyor wheel 314 to move down and roll and press the quilted cylinder 315. The pitch angle of the conveying actuator 3 is adjusted by the first electric lifting rod 206 so that the direction of the conveying actuator 3 conveying the quilted cylinder 315 can be adapted to the tilt angle of the deep hole, ensuring that the quilted cylinder 315 can be conveyed at an angle parallel to the deep hole, and avoiding the problem of the quilted cylinder 315 being subject to greater resistance during the conveying process.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
