Description

Technical Field

[0001] The invention relates to the technical field of coal mine drilling machines, and in particular to a supporting device for a double-arm anchor drilling vehicle. Background Art

[0002] At present, most of the tunneling in coal mines in my country adopts anchor support. Many underground anchor supports use single anchor drilling rigs, which generally have problems such as low automation level, low anchoring efficiency, high labor intensity, poor working environment, and poor safety. A better solution is to use anchor drilling vehicles to replace single anchor drilling rigs, improve anchoring efficiency, enhance anchoring safety, and achieve cross-operation with tunneling machines.

[0003] After the anchor drill vehicle enters the coal mine site, it is necessary to support the roof of the coal mine site (or the top of the mine cave and other parts that are prone to collapse) to avoid accidents such as roof collapse, and the supporting components in the prior art are mostly independently set. Since the anchor drill vehicle occupies a large area, the staff can only carry and assemble the components through narrow roads, and the process of independently setting up the supporting components has great construction inconvenience. Therefore, many anchor drill vehicles are equipped with a support mechanism for supporting the ceiling; however, due to the different environments at the coal mine site, the support mechanism installed on the anchor drill vehicle in the prior art is difficult to cope with support operations in various terrains. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a support device for a double-arm anchor drilling vehicle, which effectively ensures the safety of the anchor drilling vehicle operators and realizes the full adaptability of the support mechanism to different tunnel sections.

[0005] The object of the present invention is achieved in that:

[0006] A supporting device for a double-arm anchor drilling vehicle comprises a column, a telescopic arm, a first guard arm and a second guard arm, wherein an opening is provided at one end of the column and a column inner sleeve which can reciprocate linearly along the length direction of the column is provided in the corresponding opening, and the bottom of the column is arranged on a mounting plate of a mounting seat; the top of the inner sleeve of the column is connected to one end of the telescopic arm, and the inner sleeve of the column is connected to the telescopic arm through a second angle adjustment cylinder; the other end of the telescopic arm is connected to a hydraulic swing cylinder, and a guard arm mounting seat is connected above the hydraulic swing cylinder, and the left and right sides of the guard arm mounting seat are respectively connected to the first guard arm and the second guard arm, and a connecting column is provided below the end of the telescopic arm, which is connected to a supporting foot through the connecting column, and a third angle adjustment cylinder is provided at the end of the supporting foot to connect to the telescopic arm.

[0007] Furthermore, the first guard arm and the second guard arm are hinged to the guard arm mounting seat through a pin shaft.

[0008] Furthermore, the other end of the telescopic arm is connected to a swing cylinder mounting seat, and a hydraulic swing cylinder is arranged on the swing cylinder mounting seat.

[0009] Furthermore, the first guard arm and the second guard arm are retractable sleeve structures.

[0010] Furthermore, the supporting foot is a retractable sleeve structure.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The support mechanism of the present invention operates relatively independently from the working mechanism, and has no influence or restriction on the working mechanism, thus realizing the unified combination of support reliability and drilling comprehensiveness, improving work efficiency, and expanding the industry direction;

[0013] (2) The present invention controls each telescopic mechanism and driving mechanism through an adaptive control system to automatically adjust the support angle and height position, thereby realizing the automation of support. The unfolding of the two guard arms is combined with the support feet to form a T-shaped support structure, which ensures the reliability of the support, maximizes the supporting force, and effectively protects the safety of the anchor drilling vehicle operators;

[0014] (3) The present invention adjusts the height and inclination angle of the guard arm by adjusting the telescopic amount of the column and the telescopic arm, and the swing angle, thereby ensuring full contact between the guard arm and the tunnel roof and realizing full adaptability of the support mechanism to different tunnel sections; at the same time, the guard arm can also be extended to increase the supporting area, thereby being suitable for ceilings of different sizes and having better versatility.

[0015] (4) The present invention can complete the drilling construction of the entire section in one positioning, which greatly shortens the support operation time and improves the support efficiency. It adopts hydraulic power and a double-arm structure to reduce labor intensity and improve the drilling support efficiency. The drilling vehicle can be folded and retracted, and has strong passability. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Working principle:

[0051] All the above telescopic structures and hydraulic drives are controlled by the automatic control system, and the action stroke is as follows:

[0052] The first step is to control the mounting base to rotate to a certain angle to the working point in the tunnel;

[0053] The second step is the operation of the support mechanism: first, the column extends out of the inner sleeve of the column, so that the support mechanism rises to a certain height, and then the telescopic arm extends to the support point, and then the first guard arm and the second guard arm are unfolded to both sides to the same axis, and the hydraulic swing cylinder controls its tilt direction to be parallel to the top surface of the tunnel, and at the same time, the guard arm is extended to support the top surface of the tunnel, and then the second angle adjustment cylinder is used to adjust the telescopic arm to lift it upward, and finally the support leg is extended to support the ground; the first guard arm and the second guard arm form a T-shaped structure with the support leg to form a reliable support;

[0054] The third step is the operation of the working mechanism: first, the telescopic mechanism is lifted to a vertical state through the first angle adjustment cylinder, at which time the working mechanism is located between the main machine body and the support foot; the power head drives the drill rod to drill upwards, and the position of the drilling hole can be controlled according to the adjustment height of the telescopic mechanism and its rotation angle; when the carriage assembly rotates to the horizontal direction, the power head drives the drill rod to drill holes on both sides of the tunnel, and the position of the drilling hole can be controlled according to the adjustment height of the telescopic mechanism and its rotation angle;

[0055] When the connecting sleeve on the mounting seat is extended, the working mechanism can be located in front of the supporting foot, and holes can also be drilled in all directions. Therefore, the working mechanism and the supporting mechanism operate relatively independently. The supporting mechanism provides stable support without affecting the operation of the working mechanism or limiting the position of the working mechanism. The working mechanism can drill holes in all directions.

[0056] The same applies when the supporting mechanism and working mechanism are folded up.

[0057] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the present invention.
