Description

Technical Field

[0001] This utility model relates to the field of coal mining face technology, specifically to a drilling platform for anchor bolt and cable construction along the goaf. Background Technology

[0002] The traditional coal mining process in a fully mechanized longwall face involves first excavating two roadways, then mining the coal between the two roadways. The mined area, along with the roadways, collapses and is then treated, and the same method is used to continue mining the subsequent coalfields.

[0003] With the development of technology, in order to improve efficiency and roadway utilization, one of the roadways will be retained during the mining process and used as a shared roadway for the next coal mining area. However, the goaf is a subsidence area, which will affect the safety of this shared roadway. Therefore, the existing solution is to build a protective wall in the roadway as mining progresses to ensure the safety of the area.

[0004] The work area for building safety walls is usually arranged at the tail of the end support. As the end support moves, the wall is built behind it. The outer side of the wall area is a row of roadway supports, and the inner side is a row of retaining supports facing the goaf. The area where the wall is built is part of the edge of the goaf. This area has insufficient construction safety due to the lack of support structure, so it is necessary to carry out anchor bolt and cable operations on its top to improve the support effect of the top.

[0005] Currently, there is no dedicated equipment to complete this process. The core work of anchor bolt and anchor cable operation is drilling. Therefore, there is an urgent need to develop a dedicated equipment for drilling anchor bolts and anchor cables in the masonry work area.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by providing a drilling platform for anchor bolt and cable construction along the goaf, which improves the safety of wall construction, facilitates drilling, and is compatible with the working rhythm of coal mining faces.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a drilling platform for anchor bolt and cable construction along the goaf, comprising a working platform and an anchor bolt and cable operation drilling rig set up based on the working platform; The working platform includes a base and a sliding platform mounted on the base. The front end of the base is provided with a connecting part for connecting the tail end of the end bracket. The sliding platform can be moved outward to one lateral end of the base. The drilling rig for anchor bolt and anchor cable operation is installed on the outward side of the sliding platform. The area on the sliding platform away from the outward side is set as an operating platform.

[0009] The drilling platform designed in this utility model has a base connected to the end support, which moves in step with the end support and overlaps with the working area of ​​the anchor bolts and cables. The unidirectional outward sliding platform is used to gradually move laterally from the roadway to the goaf for drilling and operation. This avoids placing equipment and personnel below the unsupported area. The operators and the main body of the platform are always below the area after the anchor bolt and cable operation to ensure the safety of the operation. After the operation in this area is completed, the support work is completed, and a safe area is formed below for the workers to continue building the wall.

[0010] Based on the above, a primary sliding drive mechanism is provided between the sliding platform and the base. The primary sliding drive mechanism is a first pushing cylinder, and the two ends of the first pushing cylinder are respectively hinged to the base and the bottom of the sliding platform.

[0011] When the required support width of the support surface is narrow, or when the pushing stroke of the hydraulic cylinder is large, a self-level sliding drive mechanism can be used.

[0012] Based on the above, a two-stage sliding drive structure is provided between the sliding platform and the base. The two-stage sliding drive structure includes a first pushing cylinder, a first-stage moving platform, and a second pushing cylinder. The cylinder body end of the first pushing cylinder is hinged to the base, and the rod end is hinged to the first-stage moving platform. The cylinder body end of the second pushing cylinder is hinged to the first-stage moving platform, and the rod end is hinged to the bottom of the sliding platform.

[0013] When the stroke of the hydraulic cylinder is short, a two-stage drive can be used to increase the stroke.

[0014] Based on the above, a safety fence is provided at the operating platform, a standing position is provided inside the fence, and a control console for controlling the operation of the sliding platform and the drilling rig for anchor bolt and anchor cable operations is configured inside the fence.

[0015] To maximize the safety of manual operations.

[0016] Based on the above, the operating platform is a height-adjustable platform. This allows operators to inspect the area after work or provides a better field of vision.

[0017] Based on the above, the drilling rig used for anchor bolt and anchor cable operations is a rotatable drilling rig with at least a double-jointed robotic arm. This provides greater operational flexibility, increases its lateral offset distance, and expands the operating range.

[0018] This utility model has substantial features and advancements compared to existing technologies. Specifically, based on the operating logic of various devices in the goaf-keeping roadway, this utility model configures the platform, connects the base to the tail end of the end support so that it can move forward with the end support, and then configures a sliding platform that can move unidirectionally in the lateral direction for gradually moving, drilling, and operating from the roadway to the goaf area, ensuring the safety of the operation. The provided drilling rig is used for the drilling needs of anchor bolt and anchor cable operations. With the assistance of this platform, the execution efficiency of safety protection work in the wall-building operation area is higher, the operation quality is better, and it can meet the work rhythm needs of the coal mining face.

Detailed Implementation

[0028] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0029] like Figures 1-8 As shown, a drilling platform for anchor bolt and cable construction along a goaf includes a working platform and an anchor bolt and cable drilling rig 2 set up on the working platform.

[0030] The working platform includes a base 3 and a sliding platform 1 mounted on the base 3. The front end of the base 3 is provided with a connecting part 31 for connecting the tail end of the end bracket 4. The connecting part is a lug plate, which is fixed to the tail end of the end bracket 4 by a pin. The sliding platform 1 can be moved outward to one side of the base 3. The drilling rig 2 for anchor bolt and anchor cable operation is installed on the outward side of the sliding platform 1. The area on the sliding platform 1 away from the outward side is set as an operating table 5.

[0031] Specifically, in this embodiment, a two-stage sliding drive structure is provided between the sliding platform 1 and the base 3. The two-stage sliding drive structure includes a first pushing cylinder 6, a first-stage moving platform 7, and a second pushing cylinder 8. The cylinder body end of the first pushing cylinder 6 is hinged to the base 3, and the rod end is hinged to the first-stage moving platform 7. The cylinder body end of the second pushing cylinder 8 is hinged to the first-stage moving platform 7, and the rod end is hinged to the bottom of the sliding platform 1.

[0032] Since the stroke of a standard hydraulic cylinder is limited, a two-stage drive is used to increase the stroke, while also avoiding an increase in investment costs.

[0033] When the investment cost can be increased, as a preferred embodiment, a single hydraulic cylinder can be used to drive the sliding platform to move.

[0034] A safety fence is installed at the operating platform 5, and a standing position is set inside the fence. A control console for controlling the sliding platform and the drilling rig for anchor bolt and anchor cable operations is set inside the fence. This arrangement, by keeping the operating platform 5 away from the work area and only gradually moving it to this side after the anchor bolt and anchor cable operations are completed, can maximize the safety of manual operations.

[0035] In this embodiment, the drilling rig 2 for anchor bolt and anchor cable operation is a rotatable drilling rig with at least a double-jointed robotic arm. This type of drilling rig is obtained through procurement and selection. The appropriate specifications of the drilling rig can be selected according to the specific working environment. Its main purpose is to provide more flexible working capabilities and increase its lateral offset distance, thereby increasing the working range.

[0036] In a preferred embodiment, the operating platform is a height-adjustable operating platform, which allows operators to inspect the area after work or to provide a better working view.

[0037] Technical principle explanation: As shown in the figure, the working platform 10 moves forward along with the end support 4. The area on its left is the goaf 11 and the area on its right is the goaf retaining roadway 12. A row of rock-blocking supports 13 is set near the goaf 11, and a row of roadway supports 14 is set in the goaf retaining roadway 12. The wall 15 to be built is located between the two rows of supports. Since this area is the area left after the goaf is mined out, there is no support on the top. Before building the wall 15, the top needs to be supported by anchor bolts and cables.

[0038] During actual construction, since the end support 4 moves in a step-by-step manner, the masonry work of the wall 15 needs to be carried out in coordination with the progress of the end support 4, and the anchor bolt and anchor cable work also needs to be carried out simultaneously.

[0039] The end support 4 moves forward one step, dragging the work platform 10 forward one step as a whole, and begins the work on the overhead area. The worker's initial position is in a safe area within the roadway. The drilling rig 2 used for anchor bolt and anchor cable work drills holes in the overhead area of ​​the adjacent roadway and installs anchor bolts. After the work is completed, the worker moves laterally a certain distance and repeats the above process. It should be noted that the worker's working position must always be below the existing anchor bolt and anchor cable structure to ensure safety. The worker should not move too much at once, as this may easily cause danger.

[0040] like Figures 4-7 The diagram shows the sliding platform 1, the drilling rig 2 for anchor bolt and anchor cable operations, and the operating platform 5 in different states.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
