Description

Technical Field

[0001] The invention relates to the technical field of detection drills, in particular to an excavation working mechanism which can be quickly connected to the detection drill. Background Art

[0002] At present, in the tunnel excavation construction of coal mines and non-coal mines, the safety requirement of "exploration before excavation" must be strictly implemented. Therefore, preliminary safety detection and inspection work such as water and gas detection must be carried out before tunnel excavation. At present, most of the detection equipment used are crawler tunnel drilling rigs or advance detection drills, etc. This type of equipment is specially used for gas or water detection near the tunnel, and the detection distance is limited. Once the detection is completed, the equipment must immediately withdraw from the working face so that tunnel excavation equipment such as drilling rigs and excavator loaders can enter the working face for operation; and when the tunnel excavation has completed the detection distance, the tunnel drilling rig or advance detection drill enters the working face to detect the next excavation distance, and this cycle is repeated. There are multiple tunnel excavation equipment with different functions that need to "pass" in the narrow tunnel, which poses a safety hazard.

[0003] When drilling detection holes in the mine, in order to reduce the number of times the equipment enters and exits the working surface, the detection holes are drilled as deep as possible during operation. Therefore, it is easy to fail to drill or the drill bit is stuck due to the hole being too deep. In serious cases, the drill rod or drill bit cannot be withdrawn, resulting in waste. This type of detection drill rig is large in size, occupies the space of the tunnel, is inconvenient to enter and exit the working surface, and affects the efficiency of tunnel excavation. In addition, due to the single function of this type of equipment, the utilization rate is not high, the idle time is long and it is easy to rust and damage. Summary of the invention

[0004] The purpose of the present invention is to provide an excavation working mechanism that can be quickly connected to a detection drill rig to solve the problems existing in the above-mentioned prior art, to make the detection drill rig modular, to facilitate the modification of existing equipment, to achieve exploration while digging during tunnel excavation, and to improve the efficiency and safety of tunnel excavation.

[0005] To achieve the above object, the present invention provides the following solutions:

When the bucket is connected to the excavation working mechanism, the excavation working mechanism is used to excavate loose rocks or coal mines, and when the detection drill is connected to the excavation working mechanism, the excavation working mechanism is used to detect engineering holes near the drill tunnel.

Thus, the use of shaft drills or advanced detection drill rigs is cancelled, the types of equipment and operating personnel are reduced, equipment management is simplified, and the problems of drill rod jamming or drill sticking due to drilling deep holes or inability to drill through hard rock by shaft drills or advanced detection drill rigs are avoided; "drilling while tunneling" is realized during the roadway tunneling process, and the drilling angle can be flexibly adjusted.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0028] The object of the present invention is to provide an excavation working mechanism that can be quickly connected to a detection drill rig, so as to solve the problems existing in the prior art, modularize the detection drill rig, facilitate the transformation of existing equipment, realize the detection during tunneling, and improve the efficiency and safety of tunneling.

[0029] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] As Figures 1 to 10 shown: This embodiment provides an excavation working mechanism that can be quickly connected to a detection drill rig, including an excavation working mechanism 1 and a detection drill rig. The end of the excavation working mechanism 1 is detachably connected to a detection drill rig or a bucket through a quick connector 2. The excavation working mechanism 1 is hinged to a roadway tunneling device 12 through a boom seat, so that the excavation working mechanism 1 can rotate in a horizontal plane. When a bucket is connected to the excavation working mechanism 1, it is used to excavate loose rocks or coal mines. When a detection drill rig is connected to the excavation working mechanism 1, it is used to detect engineering holes near the roadway. The roadway tunneling device 12 is a conventional crawler-type or wheel-type excavator-loader, drill-loader or drill-bolter in the art.

[0031] The detection drill rig 6 is sequentially connected to two swing cylinders. The swing cylinder at the end is detachably connected to the quick connector 2 through a mounting seat 10, and the drilling module can swing in the horizontal plane and the vertical plane respectively. Two pin shafts 11 are arranged on the mounting seat 10 at different heights, and the pin shafts 11 can be connected to the rotatable hook 3 of the quick connector 2, which is convenient for quick disassembly and connection. The swing cylinder includes a transverse swing cylinder 4 and a longitudinal swing cylinder 5 that are perpendicularly connected. The transverse swing cylinder 4 or the longitudinal swing cylinder 5 is connected to the detection drill rig 6. The swing angle of the swing cylinder is ±180°, and the specific swing angle can be selected according to the working conditions. With the movement of the excavation working mechanism 1, drilling can be carried out at any position on the left and right sidewalls, top and bottom of the roadway in a three-dimensional space (as Figures 1 - 6 shown).

[0032] The detection drill rig 6 includes a carriage 7, a guiding mechanism 8 and a power head 9. The guiding mechanism 8 is arranged at the front end of the carriage. The power head 9 is slidably arranged on the carriage 7. A drill rod and a drill bit are sequentially connected to the power head 9. The drill rod penetrates through the guiding mechanism 8, and the carriage 7 is connected to a slewing mechanism.

[0033] In this embodiment, the functions of an excavation and exploration drill are integrated onto the excavation working mechanism 1, integrating multiple functions into one, achieving an organic combination of excavation and loading and exploration drilling, forming a new type of excavation and exploration boom structure. This enables the roadway tunneling equipment 12 to no longer require special equipment such as a tunnel drill or an advanced exploration drill for water and gas exploration, reducing the types of equipment and the number of operating personnel, simplifying equipment management, increasing the equipment utilization rate and the roadway tunneling efficiency. The function switching is convenient, the operation is simple, and the safety of roadway construction is improved; during the excavation and loading operation, the drilling for water and gas exploration holes can be carried out at any time to achieve "exploration while excavating". Therefore, the depth of a single exploration drill hole does not need to be as deep as that of a tunnel drill or an advanced exploration drill, thus avoiding the problems of drill rod jamming or drill sticking when drilling deep holes or being unable to drill through hard rock encountered by a tunnel drill or an advanced exploration drill.

[0034] Specific examples are used in this specification to elaborate on the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation on the present invention.
