Description

Technical Field

[0001] The present invention relates to the technical field of roadway driving machinery and its peripheral supporting facilities, and particularly to a single-track seven-arm hydraulic bolt drill jumbo with integrated advanced support and pressure relief. Background Art

[0002] Currently, in roadway driving construction in coal mines or non-coal mines in China, equipment such as roadheaders, rock drilling jumbo, tunnel drills (for drilling water and gas exploration holes), bolt drill jumbos, and drill loading units all use crawler or tire-type equipment for ground travel. Such ground-traveling roadway construction equipment occupies a certain ground space size. Since the cross-sectional size of the roadway is relatively narrow, when these devices need to enter the narrow roadway for construction operations, the construction equipment of the previous process must be withdrawn first, and then the equipment of this process can drive in and perform corresponding construction operations. During this process, there is a relatively long period of "empty roof". If the geological conditions are poor and there is a large rock burst, the roadway is prone to collapse during the empty roof, and serious accidents may occur, which is prohibited by the "Coal Mine Safety Regulations". In addition, in order to ensure the safe passing of construction equipment, some mines widen the roadway, and some mines make "passing bays" at certain intervals in the roadway. Whether it is widening the roadway or making "passing bays", it will affect the geological structure and increase the cost of roadway driving and support. And the frequent entry and exit of equipment in the roadway for passing will take a lot of time, and a lot of manual cooperation is required to command backing or driving in, etc. Coupled with poor lighting in the roadway, collisions are also likely to occur during the passing process. Therefore, whether it is the "empty roof" or passing, there are safety hazards and it affects the construction efficiency, resulting in a low driving footage of the roadway.

[0003] Now there are also suspended rail drilling and anchoring equipment on the market, but such suspended rail equipment does not have the function of drilling exploration holes. During the process of coal mine roadway driving, the principle of "drilling must be carried out for every driving" must always be adhered to, that is, as long as roadway driving is carried out in a coal mine, it is necessary to first conduct exploration of water or gas (gas) etc. Therefore, when driving a roadway in a coal mine, a tunnel drill is still required to drill exploration holes such as water and gas exploration. Most of these tunnel drills are installed on a chassis with crawler or tire travel, so there is also an alternating operation phenomenon with the roadheader, that is, there is "ground passing".

[0004] Therefore, how to change the current situation of potential safety hazards and low construction efficiency during the roadway driving construction process in the existing technology has become an urgent problem for those skilled in the art to solve. Summary of the Invention

[0042] The present invention provides an integrated advanced support and pressure relief single-rail seven-arm hydraulic bolt drill rig, which includes a suspended rail 1, a main frame 2, an advanced support assembly 3, a working platform 4, a bolt drill rig assembly 5, a pressure relief hole drill rig assembly 6, and a drive assembly 7. The suspended rail 1 is fixed to the top of the roadway; the main frame 2 is slidably connected to the suspended rail 1; the main frame 2 is connected with a gantry seat body 201 and a sliding seat 202. Along the advancing direction of the main frame 2, the gantry seat body 201 is located in front of the main frame 2; the gantry seat body 201 is connected with a telescopic beam 203, and the telescopic beam 203 is slidably connected to the gantry seat body 201. The sliding direction of the telescopic beam 203 relative to the gantry seat body 201 is perpendicular to the advancing direction of the main frame 2; the sliding seat 202 is slidably arranged on the main frame 2; when the equipment walks to the working face, it needs to stop and open the telescopic support legs 204 on the left and right of the gantry seat body 201 to enhance stability. When the equipment needs to start walking again after the construction is completed, the telescopic support legs 204 on both sides of the gantry seat body 201 are folded and retracted, and are misaligned and overlapped with the advanced support assembly 3 in the structural position, without occupying the passing height space.

[0043] Along the advancing direction of the main frame 2, the advanced support assembly 3 is located in front of the gantry seat body 201, and the advanced support assembly 3 is hinged to the main frame 2. The advanced support assembly 3 includes a support platform 301, and the width of the support platform 301 can be changed; along the advancing direction of the main frame 2, the working platform 4 is located behind the gantry seat body 201, and the working platform 4 is located at the bottom of the main frame 2. The working platform 4 is movably connected to the main frame 2 by a wing-type arm mechanism 8. One end of the wing-type arm mechanism 8 is hinged to the sliding seat 202, and the other end of the wing-type arm mechanism 8 is hinged to the working platform 4. The wing-type arm mechanism 8 can change the vertical distance between the working platform 4 and the main frame 2, so as to realize the lifting of the working platform 4; during work, the working platform 4 is lowered to a suitable position for construction by the wing-type arm mechanism 8 installed on the main frame 2; when walking or in a non-working state, the working platform 4 is lifted by the wing-type arm mechanism 8 and retracted at both ends of the main frame 2, and the bottom surface is approximately flush with the bottom surface of the main frame 2. The three are misaligned and overlapped in the structural position, without occupying the passing height space.

[0044] There are four groups of anchor drilling rig assemblies 5, which are movably arranged on the working platform 4 and located on both sides of the suspension rail 1. The four groups of anchor drilling rig assemblies 5 are arranged between the gantry body 201 and the wing arm mechanism 8. The anchor drilling rig assembly 5 is installed on the working platform 4 through a hinged shaft, and the opening and retracting and folding states of the anchor drilling rig assembly 5 are adjusted by the extension and retraction of the drill arm flip cylinder. When the drill arm flip cylinder is extended, the anchor drilling rig assembly 5 is opened and erected, and is in a working state; when the drill arm flip cylinder is retracted, the anchor drilling rig assembly 5 is retracted and folded on the working platform 4. When the wing arm mechanism 8 raises the working platform 4 and folds it at both ends of the main frame 2, the anchor drilling rig assembly 5 is integrated with the working platform 4, and overlaps with the main frame 2 in a dislocated manner, and does not occupy the height space of the vehicle.

[0045] There are three groups of pressure relief hole drilling rig assemblies 6, one group of which is movably arranged on the gantry body 201, and the other two groups of pressure relief hole drilling rig assemblies 6 are movably arranged on the working platform 4 and are located on both sides of the suspension rail 1, and the wing arm mechanism 8 is located between the anchor drilling rig assembly 5 and the two groups of parallel pressure relief hole drilling rig assemblies 6; the driving assembly 7 is transmission-connected to the main frame 2, and the driving assembly 7 can drive the main frame 2 to reciprocate; wherein, the telescopic beam 203, the support platform 301 and the working platform 4 are all connected with the telescopic legs 204, and the telescopic legs 204 are respectively hingedly connected to the telescopic beam 203, the support platform 301 and the working platform 4.

[0046] The single-rail seven-arm hydraulic anchor drilling vehicle with integrated advance support and pressure relief of the present invention has a main frame 2 that reciprocates along the suspended rail 1 during operation, does not occupy the ground space in the tunnel, and changes "ground vehicle passing" to "air vehicle passing", saving auxiliary time and labor costs caused by vehicle passing with ground equipment, thereby improving the efficiency of tunnel excavation construction; at the same time, the advance support assembly 3 adjusts the width area of ​​the support platform 301 according to operational needs to complete the support of the tunnel top, second side or head surface, thereby ensuring construction safety. The single-track seven-arm hydraulic anchor drilling vehicle with integrated advance support and pressure relief of the present invention adopts a seven-arm structure, including four groups of anchor drilling rig assemblies 5 and three groups of pressure relief hole drilling rig assemblies 6. The front pressure relief hole drilling rig assembly 6 is arranged on the gantry body 201, the four groups of anchor drilling rig assemblies 5 are arranged at the front end of the working platform 4, and the two groups of pressure relief hole drilling rig assemblies 6 are arranged at the rear end of the working platform 4. The overall layout of the machine is reasonable, which can meet the needs of advance support and drilling pressure relief holes in coal mine excavation tunnels and has high operating efficiency.

[0047] In addition, for the integrated single-track seven-arm hydraulic bolt drill rig for advanced support and pressure relief of the present invention, a gantry seat body 201 is connected to telescopic legs 204 to increase the support span and provide stable support for the main frame 2. During operation, a sliding seat 202 drives a working platform 4 to slide back and forth along the direction of the suspension rail 1 to balance the stress conditions of the front and rear hanging points of the main frame 2, improve the stress uniformity of the hanging points, further increase the safety factor of roadway tunneling construction, and extend the service life of the device.

[0048] Specifically, the telescopic leg 204 includes an inner leg sleeve and an outer leg sleeve. The outer leg sleeve is slidably sleeved outside the inner leg sleeve. By changing the relative position of the outer leg sleeve and the inner leg sleeve, the length of the telescopic leg 204 can be adjusted. One end of the outer leg sleeve away from the inner leg sleeve is hinged to a telescopic beam 203, a support platform 301, or a working platform 4. When the device is moving or in a non-working state, it is convenient to flip and retract the telescopic leg 204, facilitating the overall movement of the device and avoiding affecting the normal operation of other equipment.

[0049] In this specific embodiment, the radial cross-sections of both the outer leg sleeve and the inner leg sleeve are polygonal, or the outer leg sleeve and the inner leg sleeve are provided with side facades to prevent the telescopic leg 204 from rotating during the process of adjusting its length and improve the support reliability of the telescopic leg 204.

[0050] In other specific embodiments of the present invention, one end of the inner leg sleeve away from the outer leg sleeve has a support plate. The radial cross-sectional area of the support plate is larger than that of the inner leg sleeve. The provision of the support plate can increase the contact area between the telescopic leg 204 and the ground and improve the support stability. At the same time, the support plate can also block the inner leg sleeve to prevent sewage or debris from entering the inner leg sleeve and extend the service life of the telescopic leg 204.

[0051] More specifically, a guide rod is connected to the main frame 2. The sliding seat 202 has a guide rod hole adapted to the guide rod. The sliding seat 202 is slidably sleeved outside the guide rod. The provision of the guide rod and the matching guide rod hole can better provide a limiting function for the reciprocating sliding of the sliding seat 202 and improve the movement accuracy of the sliding seat 202.

[0052] To further reduce the frictional resistance when the sliding seat 202 reciprocates along the guide rod, a friction-reducing sleeve is provided in the guide rod hole to improve the wear resistance of the guide rod hole.

[0053] It should also be noted that the sliding seat 202 is connected with a roller 205. The roller 205 is rotatably connected to the sliding seat 202. The roller 205 abuts against the main frame 2. The provision of the roller 205 to roll reciprocally along the main frame 2 reduces the friction between the sliding seat 202 and the main frame 2 and improves the reliability of the device.

[0054] Furthermore, both the roof bolter assembly 5 and the pressure relief hole drilling rig assembly 6 are connected to the work platform 4 by means of telescopic arms 9, and the length of the telescopic arms 9 can be changed. Each set of telescopic arms 9 is connected to a set of roof bolter assembly 5 or pressure relief hole drilling rig assembly 6, and each drilling rig operation valve is arranged on the telescopic arm 9, which is convenient for closely observing the drilling condition during operation. Each drilling rig is operated independently to avoid mutual interference.

[0055] It should also be noted that mounting seats are provided on the telescopic arms 9. Both the roof bolter assembly 5 and the pressure relief hole drilling rig assembly 6 are hinged to the mounting seats. The mounting seats correspond to the telescopic arms 9 one by one, and the number of mounting seats is equal to the sum of the number of the roof bolter assembly 5 and the pressure relief hole drilling rig assembly 6. The provision of mounting seats on the telescopic arms 9 facilitates the disassembly and assembly of the roof bolter assembly 5 and the pressure relief hole drilling rig assembly 6, and is convenient for the operators to overhaul and maintain.

[0056] Furthermore, the advanced support assembly 3 further includes support arm assemblies 302. The number of the support arm assemblies 302 is two groups. The two groups of support arm assemblies 302 are arranged on both sides of the support platform 301 with the suspension rail 1 as the axis of symmetry. The provision of support arm assemblies 302 on both sides of the support platform 301 is to support the side walls of the roadway, which is convenient for the support work and further improves the construction safety factor. The support arm assemblies 302 are hinged to the support platform 301, which is convenient for retraction. The length of the support arm assemblies 302 can be changed to improve the flexible adaptability of the support arms. In the advanced support assembly 3 of the present invention, the surface area of the support platform 301 can be changed, which is convenient for the equipment to enter and exit the roadway, and at the same time effectively supports the roadway. In cooperation with the support arm assemblies 302, it provides a safe and reliable support for the roadway and ensures the construction safety.

[0057] During the operation of the integrated single-rail seven-arm hydraulic roof bolter with advanced support and pressure relief of the present invention, the main frame 2 reciprocates along the suspension rail 1, without occupying the ground space in the roadway. It changes from "ground passing" to "aerial passing", saving the auxiliary time and labor costs generated by passing with ground equipment, etc., and improving the construction efficiency of roadway tunneling. At the same time, the advanced support assembly 3 adjusts the surface area of the support platform 301 according to the operation needs to complete the support of the top, two side walls or the heading face of the roadway, ensuring the construction safety. The integrated single-rail seven-arm hydraulic roof bolter with advanced support and pressure relief of the present invention adopts a seven-arm structure, including four groups of roof bolter assemblies 5 and three groups of pressure relief hole drilling rig assemblies 6. The front pressure relief hole drilling rig assembly 6 is arranged on the gantry seat body 201, the four groups of roof bolter assemblies 5 are arranged at the front end of the work platform 4, and the two groups of pressure relief hole drilling rig assemblies 6 are arranged at the rear end of the work platform 4. The whole machine is reasonably arranged, can meet the needs of advanced support and drilling pressure relief holes in coal mine tunneling roadways, and has high operation efficiency.

[0058] In addition, the drive assembly 7 of the present invention is also connected to an electrical assembly, a hydraulic assembly, and a power station assembly to provide driving force for various parts and components of the equipment and ensure the normal operation of the equipment.

[0059] Specific examples are used in the present invention to illustrate the principle and implementation manner 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 manner and application scope.
