Description

Technical Field

[0001] The present invention belongs to the field of safety equipment for mining or tunnel construction, and relates to the research, development and application of emergency rescue equipment, and in particular to a modular rescue drill suitable for mines or tunnels with various cross-sectional sizes. Background Art

[0002] With the rapid development of the economy, the excavation volume of mine lanes and tunnels is nearly 20,000 kilometers per year, and mine (tunnel) "closed door collapse" accidents occur from time to time. When people are trapped, the most effective way to rescue is to safely and efficiently build a rescue channel. At present, the rescue of mine collapse accidents is still mainly based on excavating small pilot tunnels and digging around lanes, which has low construction efficiency and poor safety. When the underground and tunnels have the conditions for construction, it is most direct, safest and most efficient to use underground rescue drilling rigs to build a large-diameter rescue channel through the collapsed section.

[0003] Large-diameter boreholes are used as escape routes in the later stage, and their diameter generally needs to be more than 600mm, which requires the drilling rig to have a large capacity and a relatively large size. However, for use in tunnels, the drilling rig needs to be as small as possible. Therefore, it is necessary to solve the contradiction between the small size design of the drilling rig and the large output capacity, the rapid transportation and loading and unloading of drilling tools in the narrow space of mine tunnels, the rapid removal of drilling slag, and the efficient collaborative operation of various auxiliary operation systems. Therefore, it is urgent to carry out the research and development of modular rescue drills for mines (tunnels) that can adapt to various cross-sectional sizes to provide equipment support for mine (tunnel) emergency rescue.

[0004] At the same time, the drilling rig can also be expanded to other engineering fields such as underground connecting tunnels, ventilation holes, drainage holes, and cable laying holes in coal mines. It is especially suitable for construction under complex geological conditions and has certain market application prospects. Summary of the invention

[0005] In order to solve the problems of low efficiency, poor safety, and the contradiction between small-size design and large-capacity output of existing mine or tunnel "gate collapse" accident rescue construction, the purpose of the present invention is to provide a modular rescue drill rig that can adapt to mines or tunnels of various cross-sectional sizes.

[0006] In order to achieve the above tasks, the present invention adopts the following technical solutions:

[0011] The casing clamping device is installed at the front end of the casing straightening device, and is divided into a left top-up mechanism and a right top-up mechanism. It is installed symmetrically with the axis of the casing straightening device as the center, and the casing is clamped by the top-up of the oil cylinders on both sides;

[0013] The power pump truck is placed on one side of the drilling rig, and the control system is integrated on the power pump truck. The signals of the drilling rig, the casing front straightening device, the multi-section combined belt conveyor, and the drilling tool multi-function transporter are fed back through sensors, and the control is implemented through the electro-hydraulic system; the drilling tool multi-function transporter is at the rear end of the drilling rig during the construction process, and is responsible for the transportation of casing and drill cuttings.

[0014] The casing rotation drive device and the auger rod rotation drive device both drive gears through hydraulic motors, the gears drive the main shaft, and the main shaft drives the casing and the auger rod to rotate, providing rotation power for the cutting tools at the front ends of the casing and the auger rod.

[0015] The casing straightening device is used to straighten the casing during the process of loading and unloading the drilling tool, ensuring the rapid loading and unloading of the drilling tool;

[0016] The casing front straightening device is used for straightening the hole mouth drilling tool during the drilling process to prevent the drilling hole from deviating.

[0017] The drilling tool transfer platform is used for transferring drilling tools between the multifunctional working vehicle and the multi-section combined drilling tool transport device.

[0018] According to the present invention, the multi-section combined propulsion device includes a first guide section, a second guide section, and a third guide section. Each guide section is processed with a guide rail, and each guide section is connected in sequence through a connecting plate. One end of the guide rail of the first guide section is processed with a plug-in boss, and both ends of the guide rail of the second guide section are processed with a plug-in groove and a plug-in boss respectively. One end of the guide rail of the third guide section is processed with a plug-in groove. During the process of connecting the guide sections in sequence, the boss is inserted into the groove to ensure the accuracy of the guide section connection, the flatness and strength of the guide rail. Seven leveling mechanisms are evenly installed on both sides of the bottom of the multi-section combined propulsion device, which can obtain power through hydraulic or electric drive, and the inclination angle adjustment of the multi-section combined propulsion device can be achieved through an electro-hydraulic control system. After the actuator in the leveling mechanism is removed, a mounting hole is formed. Bolts are passed through the mounting hole to fix the multi-section combined propulsion device on the crawler transport platform.

[0019] Specifically, the multi-section combined drilling tool transport device includes a first transport segment, a second transport segment, a third transport segment, and a fourth transport segment. Each transport segment is processed with a rack, and each transport segment is connected in sequence through a connecting plate. Each transport segment is connected using the same plug-in method as the multi-section combined propulsion device to ensure connection accuracy and strength.

[0020] Among them, the height adjustment arm of the transport device and the height adjustment cylinder of the transport device are used in combination, with 4 of each, distributed on the 4 corners of the multi-section combined propulsion device, one end of which is connected to the guide rail surface, and the other end is connected to the lower end surface of the multi-section combined drilling tool transport device, supporting the deadweight and weight of the drilling tool during the process of lifting the drilling tool by the multi-section combined drilling tool transport device.

[0021] The moving device height adjustment arm and the moving device height adjustment cylinder are also part of the supporting and stabilizing device, which assist in achieving the stabilization of the drilling rig in the up and down directions.

[0022] Specifically, the casing propulsion drive device and the auger rod propulsion drive device have two groups of large cylinders and small cylinders on the left and right sides, which are respectively installed on both sides of the casing propulsion drive device and the auger rod propulsion drive device, and the large cylinders and small cylinders on both sides are installed in the opposite order up and down, so that the plane formed by the axes of the two large cylinders and the two small cylinders is as close as possible to the axis of the main shaft of the casing propulsion drive device and the auger rod propulsion drive device to prevent unbalanced loading during the propulsion and pulling out process.

[0023] The extension and retraction of the large and small oil cylinders on both sides respectively realize the pulling out and feeding of the casing rotary drive device and the auger rod rotary drive device. The main shaft drives the pulling out and feeding of the casing and the auger rod, and cooperates with the rotary motion of the casing and the auger rod to realize efficient drilling of the collapsed body.

[0024] Specifically, the supporting and stabilizing device includes a tripod, a front stabilizing cylinder, a rear stabilizing cylinder, a side stabilizing cylinder, an upper stabilizing screw, a moving device height adjustment cylinder, and a leveling mechanism; wherein:

[0025] The tripod is installed at the rear end of the guide rail of the multi-section combined propulsion device, with one front stabilizing cylinder on each side, one end of which is hinged at the front end surface of the multi-section combined propulsion device, and the other end is connected to the gripping device and supported on the ground; there are one rear stabilizing cylinder on each side, one end of which is hinged at the rear end surface of the multi-section combined propulsion device, and the other end is connected to the gripping device and supported on the ground; there are one side stabilizing cylinder on each side, one end of which is hinged at the rear end surface of the tripod, and the other end is connected to the gripping device and supported on the side wall of the tunnel; there are 4 upper stabilizing screws, which are symmetrically installed on the upper end surface of the multi-section combined drilling tool moving device; there are 7 leveling mechanisms on each side, which are evenly installed at the bottom of the multi-section combined propulsion device.

[0026] Specifically, the specific stabilization process of the supporting and stabilizing device for the drilling rig is as follows: adjust the leveling mechanism to adjust the overall angle of the multi-stage combined propulsion device of the drilling rig, use the height adjustment cylinder of the moving device to raise the moving device to the highest position of the tunnel and lock it with a pin, adjust the four upper stabilizing screws respectively until the upper gripping device contacts the tunnel roof, and finally extend the leveling mechanism as a whole to achieve reliable stabilization of the gripping device on the upper stabilizing screw on the tunnel roof; adjust the front stabilizing cylinder to provide a reaction force for the pulling out of the casing and the auger rod, adjust the rear stabilizing cylinder to provide a reaction force for the feeding of the casing and the auger rod, and adjust the side stabilizing cylinder to provide a reaction force for the overturning moment of the drilling rig. Through the above process, the stabilization of the drilling rig in six directions, front and back, left and right, and up and down, is achieved.

[0027] Specifically, the multi-section combined belt conveyor is composed of at least a first conveying section, a second conveying section, and a third conveying section. Each section of the belt conveyor is independently driven by a motor chain mechanism. The third conveying section is supported by a support frame at one end to form an inclined surface, which is conducive to conveying the slag to a designated container. Alternatively, the number of sections can be adjusted accordingly according to the length of the feeding process.

[0028] Specifically, the control system can realize the joint control of several independent parts including the drilling rig, the casing front straightening device, the multi-section combined belt conveyor, and the drilling tool multifunctional transporter by remote control.

[0029] The modular mine or tunnel rescue drill rig adapted to various cross-sectional sizes of the present invention has the following beneficial effects:

[0030] The large-diameter pipe drill adopts a modular design. Through different combination types, it can adapt to the drilling construction of mines (tunnels) with different cross-sectional sizes. It has a wide coverage, high construction efficiency and good safety, and solves the contradiction between the small size design and large output capacity of the drill. At the same time, it stipulates the form and method of rapid disassembly and connection between each module, providing guidance and technical equipment support for mine and tunnel drilling rescue.
