DETAILED DESCRIPTION

[0033] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0034] Drilling rigs are used for prospecting, railways, roads, bridges, water conservancy and hydropower, tunnels, wells, anchors, small-diameter diamond core rope coring drilling, geological exploration, geothermal drilling, coalbed methane drilling, and anti-burst drilling. Drilling rigs are divided into percussion drilling rigs, rotary drilling rigs, vibration drilling rigs, and compound drilling rigs according to the drilling method.

[0035] In order to improve production efficiency, reduce the probability of accidents, and continuously increase the degree of mechanization in coal mining, in some embodiments, a rotary column-type hydraulic rotary drill rig is used for drilling work. Due to the simple structure of the rotary column-type hydraulic rotary drill rig, it is not possible to carry out blasting construction on the working face. When working underground, the rotary column-type hydraulic rotary drill rig is large in size and difficult to move. It has low heat dissipation efficiency and high failure rate, and cannot adapt to the narrow construction conditions of the coal mining face.

[0036] To solve the problems of large size, difficult movement and low heat dissipation efficiency of hydraulic rotary drilling rigs, refer to Figure 1-Figure 3 ,in, Figure 1 It is a schematic diagram of the structure of a narrow-body drilling rig for underground use; Figure 2 A schematic diagram of the first direction connection structure of a fuel tank body and a traveling device of a narrow-body underground drilling rig Figure 1 ; Figure 3 A schematic diagram of the second direction connection structure of the fuel tank body and the running gear of a narrow-body drilling rig for underground use Figure 2 The embodiment of the present application provides a narrow-body drilling rig for underground use, comprising: a traveling device 1 that can travel in a preset direction; a fuel tank body 2 disposed on the top of the traveling device 1; the width of the fuel tank body 2 in the positive projection of the traveling device 1 is less than or equal to the width of the traveling device 1; a support unit 6 disposed on the top surface of the fuel tank body 2; the support unit 6 is perpendicular to the top surface of the fuel tank body 2, and one end of the support unit 6 extends away from the fuel tank body 2; a drilling execution unit 4; one end of the drilling execution unit 4 is slidably connected to the support unit 6 in a vertical direction, and the other end extends in the traveling direction of the fuel tank body 2; a lifting unit 5 disposed on the fuel tank body 2; the lifting unit 5 is perpendicular to the top surface of the fuel tank body 2, and the lifting unit 5 is fixedly connected to the drilling execution unit 4; a motor pump unit 3 disposed on the fuel tank body 2, and the motor pump unit 3 is electrically connected to the drilling execution unit 4, the lifting unit 5 and the traveling device 1 respectively.

[0037] Integrating the fuel tank and the vehicle body into the fuel tank vehicle body 2 not only increases the surface area of ​​the fuel tank, but also reduces the volume of the fuel tank and the vehicle body, so that the width of both sides of the fuel tank vehicle body 2 is less than or equal to the width of the walking device 1, so as to solve the problems of large volume, difficult movement and low heat dissipation efficiency of the hydraulic rotary drilling rig.

[0038] It should be understood that the width of the orthographic projection of the support unit 6, the drilling execution unit 4, the lifting unit 5, and the motor pump unit 3 on the walking device 1 is less than or equal to the width of the walking device 1. In some embodiments, the fuel tank body 2 is embedded in the crawler frame of the walking device 1, which not only makes the connection more firm, but also reduces the size of the entire drilling rig body.

[0039] In some embodiments, the oil tank body 2 includes an oil return chamber 21, an oil suction chamber 26 and a plurality of oil tank chambers; the oil return chamber 21, the plurality of oil tank chambers and the oil suction chamber 26 are connected in sequence.

[0040] The interior of the oil tank body 2 is divided into a plurality of oil tank chambers connected in series, so that the hydraulic oil has a longer path to flow from the oil suction chamber 26 to the oil suction chamber 26, thereby improving the heat dissipation efficiency.

[0041] See also Figure 5-Figure 6 , Figure 5 It is a schematic diagram of the first direction structure of the interior of a fuel tank body of a narrow-body underground drilling rig; Figure 6 The present invention is a schematic diagram of the second direction structure inside the fuel tank body of a narrow-body underground drilling rig.

[0042] The oil tank chamber is divided into a first oil tank chamber 22, a second oil tank chamber 23, a third oil tank chamber 24 and a fourth oil tank chamber 25; the hydraulic oil passes through the return oil chamber 21, the first oil tank chamber 22, the second oil tank chamber 23, the third oil tank chamber 24 and the oil suction chamber 26 in sequence, so that the hydraulic oil with a higher temperature entering from the return oil chamber 21 is further dissipated through the oil tank chamber, and then enters the oil suction chamber 26 to contact with the original hydraulic oil, thereby further reducing the temperature difference between the hydraulic oils and improving the heat dissipation efficiency.

[0043] In some embodiments, the fuel tank body 2 further includes an oil return filter; the oil return filter is connected to the oil return chamber 21.

[0044] The oil return filter is used to filter the hydraulic oil entering the oil return chamber 21, so that the dirt such as abrasive particles generated during the working process is intercepted, and the occurrence of the dirt returning to the oil tank body 2 again is reduced.

[0045] It should be understood that the return oil filter is installed on the pipeline close to the return oil chamber 21, and various impurities such as abrasive particles generated by various hydraulic components during operation can be intercepted by the return oil filter, reducing the probability of returning to the tank body 2 again.

[0046] In some embodiments, the fuel tank body 2 further includes an oil suction filter element; the oil suction filter element is connected to the oil suction chamber 26 .

[0047] It should be understood that the oil suction filter element is installed in the fuel tank body 2 and below the liquid level of the fuel tank body 2. The filter element filter material can be selected from stainless steel woven mesh or copper mesh, which can be repeatedly cleaned and used.

[0048] The oil suction filter element is used to filter the oil before it enters the oil suction chamber 26 to remove solid particles and colloidal substances in the hydraulic oil.

[0049] In some embodiments, the motor pump group unit 3 includes an oil pump and a motor; the oil pump is connected to the motor; the oil pump includes an oil pump power input side and an oil pump power output side; the oil pump power input side is connected to the tank body 2; the oil pump power output side is connected to the drilling execution unit 4.

[0050] The oil pump is driven by the motor so that the oil pump converts mechanical power into hydraulic power and outputs it from the power output side of the oil pump to provide power to the drilling execution unit 4 .

[0051] It should be understood that the oil pump may have multiple power output sides for converting mechanical power into hydraulic power of different frequencies, respectively providing the required power to the drilling execution unit 4, the lifting unit 5 and the walking device 1 of different frequencies.

[0052] In some embodiments, the motor is an explosion-proof motor; a motor switch is provided on the motor, and the motor switch is an explosion-proof switch.

[0053] The use of explosion-proof motors and explosion-proof switches serves to isolate electrical parts that may generate sparks, arcs and dangerous temperatures from the oil pump.

[0054] The explosion-proof motor is mainly characterized by the contact surfaces between the base and the end cover, the junction box, the junction box bottom and the cover are all set as flameproof surfaces. The flameproof surface is to increase the matching area and enhance the matching accuracy in order to meet higher sealing requirements. In this part, measures such as applying sealant and adding rubber sealing pads are adopted; in addition, its junction box and the inside of the casing must also be strictly isolated to separate the electrical parts that may generate sparks, arcs and dangerous temperatures from the surrounding explosive gas mixture.

[0055] In some embodiments, see Figure 4 , Figure 4 The schematic diagram of the radiator structure of a narrow-body underground drilling rig is shown. The radiator 8 is also included; the radiator 8 includes an oil inlet 81 and an oil outlet 82; the oil inlet 81 is connected to the oil pump; and the oil outlet 82 is connected to the oil tank body 2.

[0056] The radiator 8 is used to quickly dissipate the heat of the hydraulic oil discharged from the oil pump before entering the oil tank body 2.

[0057] In some embodiments, the radiator 8 includes a plurality of blades; and the plurality of blades are arranged in a foldable manner.

[0058] A plurality of blades increase the heat dissipation area and improve the heat dissipation efficiency. The foldable arrangement can save space.

[0059] In some embodiments, an air cooling system 7 is further included, and the air cooling system 7 is arranged between the oil pump and the radiator 8 .

[0060] The air cooling system 7 is used to cool the hydraulic oil pumped out of the oil pump before entering the radiator 8 and then entering the oil tank body 2, thereby achieving the effect of preliminary cooling of the hydraulic oil.

[0061] It can be seen from the above technical scheme that the embodiment of the present application provides a narrow-body drilling rig for underground use, comprising: a traveling device 1 that can travel in a preset direction; a fuel tank body 2 arranged on the top of the traveling device 1; the width of the fuel tank body 2 in the positive projection of the traveling device 1 is less than or equal to the width of the traveling device 1; a support unit 6 arranged on the top surface of the fuel tank body 2; the support unit 6 is perpendicular to the top surface of the fuel tank body 2, and one end of the support unit 6 extends away from the fuel tank body 2; a drilling execution unit 4; the drilling execution unit One end of the element 4 is slidably connected to the support unit 6 in the vertical direction, and the other end extends to the moving direction of the tank body 2; a lifting unit 5 is arranged on the tank body 2; the lifting unit 5 is perpendicular to the top surface of the tank body 2, and the lifting unit 5 is fixedly connected to the drilling execution unit 4; a motor pump unit 3 is arranged on the tank body 2, and the motor pump unit 3 is electrically connected to the drilling execution unit 4 and the walking device 1 respectively, so as to solve the problems of large size, difficult movement and low heat dissipation efficiency of the hydraulic rotary drilling rig.
