Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, in particular to a hydraulic blasting charge pushing device. Background Art

[0002] Hydraulic blasting involves placing explosive charges at a designated location within a water-filled blasting container. Water is used as a detonation medium to transmit the explosive pressure, causing the container to collapse. Air shock waves, flying rocks, and noise are all effectively controlled. Hydraulic blasting is commonly used in tunnel construction, but traditional hydraulic blasting charges are often manually filled, a cumbersome and inefficient process. This method also poses safety risks to blasters. Summary of the Invention

[0007] Preferably, the locator is a laser locator, and the axis of the locator is highly consistent with the axis of the medicine roll and the water hose, so that the medicine roll or the water hose can be pushed into the blast hole.

[0008] Preferably, the adjustment angle α of the guide assembly is -5° to +5°, so that the guide assembly can be raised and lowered to complete the angle adjustment and align with the blast hole.

DETAILED DESCRIPTION

[0024] In order to better understand the improvements made by the present invention over the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] like Figure 1 —As shown in Figure 9, a hydraulic blasting charge pushing device is mainly composed of a chain conveyor 1, a driven shaft 8, a driving shaft 9, a guide assembly 2, a limit assembly 3, a positioner 4, a top fixing block 5, a top fixing block triggering inducer 6, and a guide assembly angle adjuster 7.

[0026] A chain conveyor 1 is mounted on one side of the hose and medicine roll assembly and storage unit 15. To ensure that the medicine rolls 12 and water hose 11 within the assembly and storage unit 15 can be automatically unloaded onto the chain conveyor 1, it is positioned outside the lower unloading opening of the assembly and storage unit 15. This facilitates direct unloading of the medicine rolls and water hose onto the chain conveyor for transport. The upper layer of the chain conveyor 1 is designed as a curved surface that mates with the medicine rolls and water hose, preventing them from falling during transport.

[0027] The guide assembly 2 is mounted at the front end of the chain conveyor 1 via a guide assembly angle adjuster 7. The guide assembly 2 has an adjustment angle α of -5° to +5°, enabling the guide assembly to be raised and lowered to achieve angle adjustment and alignment with the blasthole. The guide assembly angle adjuster 7 can be directly installed using a purchased angle adjuster.

[0028] The limiting assembly 3 is disposed on the top surface of the guide assembly 2, and a positioner 4 is provided at the front end of the limiting assembly 3. The positioner 4 is a laser positioner, and the axis of the positioner 4 is highly aligned with the axis of the medicine roll 12 and the water hose 11. This ensures that the medicine roll 3 or the water hose 2 is aligned with the axis of the blasthole during positioning and can be pushed in smoothly. After the guide assembly 2 is positioned and aligned with the blasthole by the positioner 4, the top surface of the guide assembly 2 and the limiting assembly 3 enclose the blasthole, ensuring that the medicine roll 3 and the water hose 2 enter the blasthole. The limiting assembly 3 is not limited to a limiting cover that matches the shape of the medicine roll 3 and the water hose 2, but can also be a limiting plate set on the left and right sides of the guide assembly 2.

[0029] A top-fixing block triggering guide 6 is fixedly mounted on the inner side of the top surface of the chain conveyor 1. The top-fixing block 5 is placed on a guide bracket 15a provided on the side of the hose reel assembly and storage assembly 15. The guide bracket 15a gradually tilts upward from back to front, so that the top-fixing block 5 gradually rises from sinking into the chain conveyor 1 to above the chain conveyor 1 as it is pushed forward. To provide a lifting channel for the top-fixing block 5, the middle section of the chain conveyor 1 within the travel range of the top-fixing block 5 is hollowed out.

[0030] An opening and closing mechanism is provided at the tail end of the top fixing block 5. The opening and closing mechanism includes two clamping jaws that are symmetrically arranged on the left and right and hinged together at the front end through a central axis 5a. The two clamping jaws are fixed to the inside of the top fixing block 5 by springs 5b. The top fixing block triggering inducer 6 is fixedly mounted on the chain conveyor 1. The top fixing block triggering inducer 6 can be partially inserted into the opening and closing mechanism to push the top fixing block 5 forward or drag it backward. The top fixing block triggering inducer 6 is divided into an upper part 6a and a lower part 6b. The upper part 6a is fixedly mounted on the chain conveyor 1, and the lower part 6b is connected to the upper part 6a through a thin rod. The lower part 6b is set in an overall teardrop shape with a sharp front end and a semicircular rear end, which is convenient for entering the opening and closing mechanism of the top fixing block 5. In order to ensure that when the chain conveyor 1 reverses, the lower part 6b is not easy to fall out when driving the top fixing block to reset backward in the opening and closing structure, the rear end opening width of the opening and closing mechanism does not exceed one third of the width of the opening and closing mechanism.

[0031] A limit stopper 17 is provided at the rear end of the guide bracket 15a. When the top fixing block triggering guide 6 drives the top fixing block 5 to move backward to the position of the limit stopper 17, the limit stopper 17 prevents the top fixing block 5 from continuing to move backward. At the same time, the opening and closing mechanism can open to allow the engaging portion of the top fixing block triggering guide 6 to be disengaged. When the medicine roll 12 or water hose 11 is delivered to the guide assembly 2, the top fixing block triggering guide 6 is partially engaged in the opening and closing mechanism, pushing the medicine roll 12 or water hose 11 through the top fixing block 5 until it enters the blast hole 14 at the front end of the guide assembly 2. When the medicine roll 12 and water hose 11 are delivered to the guide assembly 2, the top fixing block triggering guide 6 is partially engaged in the opening and closing mechanism, pushing the medicine roll 12 and water hose 11 through the top fixing block 5 until it enters the blast hole 14 at the front end of the guide assembly 2. When the top fixing block triggers the induction member 6 to drag the top fixing block 5 backward to the position of the limit block 17, the limit block 17 prevents the top fixing block 5 from continuing to move backward. At the same time, the opening and closing mechanism can be opened to allow the top fixing block to trigger the induction member 6 to be disengaged and separated.

[0032] Preferably, the push baffle 10 is detachably mounted on the chain conveyor 1, and different mounting positions can be selected according to the charge length, and the push baffle 10 is located in front of the top fixing block triggering induction member 6 for preliminary pushing.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
