Description

Technical Field

[0001] The utility model relates to the technical field of blasting auxiliary equipment, in particular to a mine blasting charging device. Background Art

[0002] Ore blasting refers to the operation of blasting collapsed ore. According to the different charging spaces, ore blasting is divided into blasthole blasting and chamber blasting. According to the depth of the hole, blasthole blasting is divided into shallow-hole blasting, medium-deep-hole blasting, and deep-hole blasting. According to the shape of the explosive package, ore blasting is divided into columnar explosive package blasting and spherical explosive package blasting. According to the crushing and expansion of the ore under the explosion, ore blasting is divided into free space blasting and extrusion blasting. Free space blasting means that the space (compensation space) required for the crushing and expansion of the ore under the explosion is large enough to meet the free crushing and expansion of the ore.

[0003] The traditional charging method is to load the explosives manually, but this method is extremely dangerous. Therefore, the existing charging methods are changed to loading by operating auxiliary equipment. For example, a mobile mining blasting charging device is recorded in the patent with publication number CN114777594A. The device mainly uses a trolley structure to replace manual suspension of blasting packages, and adjusts the position of the charge by controlling the position of the trolley and the lever structure on the trolley, thereby eliminating the need for manual approach to the charging area and improving safety.

[0004] However, in actual operation, the side walls of the mine are mostly rugged structures. In particular, if there is a raised part below the charge placement, the mine car cannot be accurately placed at the charge placement even if the lever structure is adjusted. Moreover, when the blasting point is located at a higher place, the lever structure on the car is also difficult to reach the height requirement. Utility Model Content

[0005] Based on the above description, the utility model provides a mining blasting charging device to solve the problem that the lever structure of the existing charging auxiliary trolley can reach a limited height during actual use and the placement effect is easily affected by the ruggedness of the blasting surface.

[0020] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0022] Combination Figure 1-3 As shown, a mine blasting charging device comprises:

[0023] The vehicle body 1 is a rectangular structure, the center of the top surface of which is concave into a box structure and is used to provide auxiliary support for other components. Rollers 11 are installed at the four corners of the bottom surface for transportation;

[0024] The lifting and adjusting component 2 is arranged inside the vehicle body 1 and can be lifted and adjusted in the vertical direction;

[0025] The conveying assembly 3 is arranged on the top of the lifting and adjusting assembly 2 and can be adjusted in the horizontal direction. A blasting charge is fixed at its end.

[0026] The hand grip 4 is disposed at one end of the vehicle body 1 and is used to assist the staff in holding and adjusting. The hand grip 4 is also provided with a control button 41 for controlling the lifting and adjusting component 2 and the conveying component 3.

[0027] Specifically, in the above structure, the lifting and adjusting assembly 2 is composed of a support frame 21 and a cylinder 22, wherein two support frames 21 are provided and are arranged on both sides of the inner bottom surface of the vehicle body 1, and each support frame 21 is connected by a plurality of groups of cross-hinged support plates, and the ends of the upper and lower groups of adjacent support plates are hinged to each other, and finally form a folding machine structure, for example Figure 2As shown, the cylinder 22 is arranged between the folding frames and controls the lifting and lowering adjustment function of the folding frames by telescoping. The two cylinders 22 are synchronously controlled, and when the cylinders 22 are contracted to the shortest, the entire folding frame is completely stored inside the vehicle body 1, and the bottom surface of the conveying assembly 3 is just in contact with the top surface of the vehicle body 1.

[0028] In combination with the above content, the cylinder 22 should adopt an electrically controlled cylinder 22, that is, a cylinder with a solenoid valve structure, such as Norgren's stainless steel cylinder, KA / 802000 / M series, etc., and then a wire is arranged, one end of which is electrically connected to the solenoid valve, and the other end passes through the vehicle body 1 and extends to the inside of the handle 4 and is electrically connected to the control button 41, so that when the staff holds the handle, it can be driven and operated synchronously.

[0029] The conveying assembly 3 includes three parts: a mounting plate 31, an electric telescopic rod 33 and a fixed plate 34. The mounting plate 31 is a rectangular plate structure and is larger than the groove part on the top of the vehicle body 1. Therefore, when the lifting and adjusting assembly 2 is completely stored in the vehicle body 1, the bottom surface of the mounting plate 31 is just in contact with the top surface of the vehicle body 1. A mounting hole 32 is also provided on the side wall surface of the mounting plate 31. The mounting hole 32 is just located on the side away from the handle 4. The main part of the electric telescopic rod 33 is just embedded in the mounting hole 32, and its telescopic end extends to the outside of the mounting plate 31. The fixed plate 34 is just arranged on the telescopic end, and when the electric telescopic rod 33 is retracted to the minimum stroke, the back of the fixed plate 34 is in contact with the side wall of the mounting plate 31.

[0030] Before blasting, holes need to be drilled in the wall surface in advance. However, the holes drilled may not match the shape of the explosive bags. After drilling, some fine gravel is likely to accumulate at the holes. Therefore, if a simple hanging method is used, the explosive bags may be obstructed and cannot be installed accurately.

[0031] Based on the above requirements, in this embodiment, an electric clamp 35 should be provided on the outward side of the mounting plate 31, such as an electric-controlled clamp structure of the AG-95 adaptive electric clamp, PGE industrial parallel small clamp, etc. The top or bottom end of the blasting charge is fixed by the clamp so that it can be pushed into the excavated hole during transportation, making the installation more precise.

[0032] In the conveying assembly 3, the electric telescopic rod 33 and the electric clamp 35 are electrically connected to the control button 41 by wires, so the staff only needs to push and pull the vehicle body 1 to the specified position to perform remote operation to prevent the explosion of the explosive package, which greatly improves safety and convenience.

[0033] In order to further improve the flexibility of the vehicle body 1, its roller 11 should adopt a universal wheel structure with a brake; further, it can also be controlled by electric drive, that is, it is equipped with a motor to drive the roller 11 to rotate, and is controlled by the control button 41 on the handle 4, so that the convenience is further improved.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
