Description

Technical Field

[0001] This invention belongs to the technical field of gas extraction and control equipment, specifically relating to a hydraulic pump station embedded in a tracked drilling rig. Background Technology

[0002] To ensure safe and efficient coal mine production, underground tunnel drilling rigs are used to pre-extract gas from the coal seam before mining to reduce its concentration. Due to the limited space in underground mine roadways, there are strict restrictions on the dimensions of the drilling rig to facilitate its transportation and relocation.

[0003] Coal mine underground tunnel drilling rigs are mainly divided into split-type drilling rigs and crawler-type drilling rigs. The hydraulic pump station of the drilling rig mainly consists of a motor pump unit, an oil tank, and a cooler. The hydraulic pump station is the core power source of the drilling rig, providing high-pressure oil to drive the drilling rig's actuators to complete the corresponding actions.

[0004] Among them, split-type drilling rigs have a simple structure and flexible layout. The hydraulic pump station adopts an upper-mounted structure, that is, the oil tank is placed above the motor pump unit, which improves the suction capacity of the hydraulic pump. However, relocation and moving to the drilling site are not easy. Tracked drilling rigs have a relatively complex structure, and more functional modules need to be arranged on the tracked vehicle platform. The functional modules on existing tracked drilling rigs include hydraulic drive components, which vary depending on the different usage scenarios. Generally speaking, hydraulic drive components include a tracked walking platform, hydraulic actuators, and electro-hydraulic control valve groups. Under this setting, due to the limitation of the overall height of the drilling rig, the hydraulic pump station usually adopts a side-mounted or side-mounted sunken structure. The side-mounted structure means that the motor pump unit and the oil tank are arranged adjacent to each other. However, this structure will increase the overall width of the drilling rig and affect its maneuverability. Summary of the Invention

Detailed Implementation

[0017] It should be noted that, unless otherwise specified, all components in this invention are components known in the prior art.

[0018] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0019] A crawler-type drilling rig with an embedded hydraulic pump station, such as Figure 1 and 2 As shown, the system includes a tracked drilling rig 1, which includes a hydraulic drive assembly. The hydraulic drive assembly includes a tracked walking platform, a hydraulic actuator, and an electro-hydraulic control valve group. The system is characterized in that an embedded hydraulic pump station is fixedly installed on the tracked drilling rig 1. The embedded hydraulic pump station includes a hydraulic oil tank 2, a motor pump unit 3, and a cooler 4; The electric pump unit includes a hydraulic pump unit and a corresponding electric motor for the hydraulic pump; The hydraulic oil tank 2 is fixedly installed at the rear side of the crawler drilling rig 1 in a recessed manner, and the lower part of the hydraulic oil tank 2 has a groove 5; the motor pump group 3 is installed on the crawler drilling rig 1, wherein the hydraulic pump group enters the groove 5 of the hydraulic oil tank 2. An embedded hydraulic pump station and its monitoring, diagnosis and treatment method are designed with an embedded hydraulic oil tank. The pump in the motor pump unit is placed in the groove 5 space of the hydraulic oil tank 2 (the pump in the motor pump unit can be a single pump, a double pump, a triple pump, etc.). The hydraulic oil tank 2 adopts a distributed pump unit suction pipeline design and a zoned and layered oil return pipeline design. This ensures that the hydraulic pump station has a small external size while realizing the reasonable and orderly distribution of the pump unit suction filter in a small space, ensuring smooth oil suction, and performing zoned and layered oil return according to the different oil return volume and heat of different hydraulic components in the hydraulic system. This facilitates oil bubble separation, sufficient cooling and impurity sedimentation, and improves the cleanliness of the hydraulic oil and the stability of the hydraulic system.

[0020] Cooler 4 is fixedly mounted in a recessed manner on one side of the front of crawler drilling rig 1; like Figure 3 and 5 As shown, the hydraulic oil tank 2 is equipped with a partition, which divides the interior of the hydraulic oil tank 2 into two parts, namely the return oil chamber 201 and the suction oil chamber 202; the return oil chamber 201 is divided into two connected upper and lower layers. The oil suction chamber 202 is equipped with an oil suction and filter device that is connected to the input end of the hydraulic pump unit; the output end of the hydraulic pump unit is connected to the oil inlet end of the hydraulic drive component. A return oil pipe assembly is provided at the return oil chamber 201 of the hydraulic oil tank 2. One end of the return oil pipe assembly is connected to the oil outlet end of the cooler 4, and the other end is sealed and enters the upper layer of the return oil chamber 201; the oil drain end of the drive assembly is connected to the oil inlet end of the cooler 4. The hydraulic oil tank 2 is equipped with an openable and closable oil inlet and outlet.

[0021] As a more specific implementation, the hydraulic pump unit includes a first pump, a second pump, and a third pump; The oil suction chamber 202 is provided with a first oil suction filter 6, a second oil suction filter 7 and a third oil suction filter 8 arranged alternately. A first oil suction connection pipe is provided on the left side of the hydraulic oil tank 2. One end of the first oil suction connection pipe is sealed and enters the oil suction chamber 202 to connect with the first oil suction filter 6, and the other end is connected to the input end of the first pump. A second oil suction connection pipe and a third oil suction connection pipe are arranged side by side in the groove 5 of the hydraulic oil tank 2; one end of the second oil suction connection pipe and the third oil suction connection pipe are sealed and enter the oil suction chamber 202 and are respectively connected to the second oil suction filter 7 and the third oil suction filter 8; the other end of the second oil suction connection pipe and the third oil suction connection pipe are respectively connected to the input end of the second pump and the input end of the third pump. The output end of the first pump is connected to the oil inlet end of the hydraulic actuator of the crawler drilling rig 1; As an optional implementation, the output end of the first pump is connected to the oil inlet end of the six-valve assembly in the electro-hydraulic control valve group; In this embodiment, the hydraulic actuator functions to rapidly rotate, rapidly feed and pull up, and move the drilling site. The electro-hydraulic control valve group controls the action of the six-valve group. The rotation and feed / pull-up actions merge to achieve rapid rotation and rapid feed / pull-up. Rapid rotation and rapid feed / pull-up are used for drilling rig tripping and raising / lowering, improving the drilling rig's rod reversing efficiency. The electro-hydraulic control valve group controls the movement of the two travel actions in the six-valve group, enabling the tracked vehicle platform to move forward, backward, and turn, thereby moving the drilling site. The output end of the second pump is connected to the oil inlet end of the motor of the tracked walking platform of the tracked drilling rig 1. As an optional implementation, the output end of the second pump is connected to the oil inlet end of both the two-valve assembly and the eleven-valve assembly in the group. In this embodiment, the hydraulic actuator functions as slow rotation and slow feed for lifting, automatic rod replenishment, and automatic drill rod loading and unloading. The electro-hydraulic control valve group controls the operation of the two-valve group to perform slow rotation and slow feed for lifting during normal drilling operations. The electro-hydraulic control valve group controls the operation of the eleven-valve group to control the automatic rod replenishment and rod loading / unloading system. The automatic rod replenishment system transfers the drill rod from the rod magazine to the rod loading / unloading system, which places the drill rod in the loading / unloading position. The automatic rod loading function of the drilling rig is achieved through the cooperation of the rotary head and the clamping and untying device. The automatic rod unloading function involves the rotary head and the clamping and untying device disassembling the drill rod to be unloaded, and the rod loading / unloading system transfers the drill rod to the automatic rod replenishment system, thereby returning it to the rod magazine.

[0022] As an optional implementation, the output end of the third pump is connected to the oil inlet end of the clamping unslip valve group and the auxiliary stabilizing valve group in the electro-hydraulic control valve group of the crawler drilling rig 1. In this embodiment, the function of the clamping and uncoupling valve group is to clamp and uncouple. The electro-hydraulic control valve group controls the operation of the clamping and uncoupling valve group. The clamping and uncoupling device is used to clamp the drill rod in the hole and the drill rod to be unscrewed, and cooperates with the rotary head to realize the unscrewing of the drill rod. The chuck is used to clamp the drill rod for drilling construction or cooperates with the clamping and uncoupling device to realize the unscrewing of the drill rod. The function of the auxiliary stabilizing valve group is to adjust the spatial attitude of the drilling rig and assist in stabilization. The electro-hydraulic control valve group controls the operation of the auxiliary stabilizing valve group, controls the six lower stabilizing devices of the drilling rig to adjust the tracked body of the drilling rig to a horizontal state and lift it off the ground to avoid sinking into the mud; controls the four upper stabilizing devices of the drilling rig to press against the roof of the tunnel to prevent the drilling rig from shaking during drilling; and controls the angle adjusting cylinder to adjust the spatial attitude of the drilling rig.

[0023] The above are all based on existing tracked drilling rig devices known in the prior art, and can be applied to existing tracked drilling rigs to achieve the above functions. The connection method between the pump and the actuator is known in the art, and those skilled in the art are capable of implementing the above operations, so it will not be described in detail here. The cooler 4 includes a first cooling pipe, a second cooling pipe, and a third cooling pipe that correspond one-to-one with the oil return ends of the hydraulic actuator, the motor of the tracked walking platform, and the electro-hydraulic control valve group. The following provides a more specific connection method: The first hydraulic pump corresponds to the six-way valve return oil; the second hydraulic pump corresponds to the two-way valve return oil, the rotary valve housing drain oil is connected to the cooler, and the oil is cooled and then enters the three return oil filters through the return oil steel pipe on the upper side of the hydraulic oil tank 2 and returns to the oil tank; the first, second and third hydraulic pump housing drain oil, the travel motor drain oil, the eleven-way valve return oil and drain oil are connected to the return oil chamber 201 of the hydraulic oil tank 2, and enter the hydraulic oil tank 2 through the internal pipeline.

[0024] It should be noted that when connecting pipes and components, connecting elbows and other devices can be used to achieve a more convenient connection, which will not be elaborated here.

[0025] The outer wall of the hydraulic oil tank 2 is provided with a third inner return oil pipe 17 and a first inner return oil pipe 15 and a second inner return oil pipe 16 arranged in parallel. One end of the first inner return oil pipe 15, the second inner return oil pipe and the third inner return oil pipe 17 are sealed and enter the upper layer of the return oil chamber, and the other end extends downward and is connected to the first cooling pipe, the second cooling pipe and the third cooling pipe respectively.

[0026] This pipeline design is suitable for environments with confined spaces in underground coal mine roadways, where there are strict limitations on drilling rig size. For drilling rigs with the same capacity, the smaller the external dimensions, the greater the applicability. While ensuring the drilling capacity remains unchanged, the size of the drilling rig should be reduced as much as possible. An embedded hydraulic pump station structure can effectively shorten the width and length of the drilling rig. However, the embedded hydraulic pump station has a complex structure; while reducing its external dimensions, it is necessary to ensure the ease of maintenance, smooth oil suction and return, and effective oil return cooling.

[0027] As a preferred embodiment, the hydraulic oil tank 2 is provided with an oil tank cover; the oil tank cover is provided with an oil filling hole that can be opened and closed, and an air filter 11 is provided at the oil filling hole; Oil return filters 12 are installed on the first internal oil return pipe 15, the second internal oil return pipe 16, and the third internal oil return pipe 17.

[0028] The hydraulic oil tank 2 is designed in layers. The internal space of the hydraulic oil tank 2 is divided into a return oil chamber 201 and a suction oil chamber 202 by a partition and the side wall of the oil tank. That is, the area where the pump suction oil filter is located is the suction oil chamber 202, and the area where the return oil pipe and return oil filter are located is the return oil chamber 201. After the return oil of the hydraulic system enters the return oil chamber 201 of the oil tank, it flows in a roundabout way to the suction oil chamber 202, which is conducive to separating air bubbles, heat dissipation and sedimentation of impurities, and improving the service life of hydraulic components.

[0029] Based on the varying return oil volume and heat of different hydraulic components in the hydraulic system, the return oil pipeline is designed in layers. Return oil pipelines with high return oil volume, high heat, and high impurity content should be located away from the suction chamber 202, with their return oil outlets positioned at the bottom of the oil tank to facilitate sufficient oil cooling, air bubble separation, and impurity sedimentation. Return oil outlets with relatively high return oil volume and heat should be located at the upper layer of the oil tank, with the return oil flowing a long, circuitous route to the suction chamber 202 under the action of baffles. The return oil outlet with the lowest return oil volume and heat can be designed at the upper layer of the return oil chamber 201, adjacent to the suction chamber 202, with the return oil flowing from the upper layer to the lower suction chamber 202, extending the return oil flow path. The main return oil from the main valve and the gearbox of the entire hydraulic system has the largest flow rate, highest heat, and carries the most impurities. After being cooled by the cooler and thoroughly filtered by three return oil filters, it returns to the oil tank. The three return oil filters are located at the furthest point from the pump suction filter in the return oil chamber 201 to facilitate air bubble separation, oil cooling, and impurity sedimentation. The three pumps have relatively large oil return volumes and carry a significant amount of heat. Therefore, their return outlets are located in the lower layer of the return oil chamber 201, furthest from the pump suction filter, i.e., the inner return oil pipe 2, to ensure sufficient cooling of the return oil. The hydraulic system auxiliary function valve group also has a relatively large return volume and carries a considerable amount of heat. Therefore, its return oil outlet is located in the upper layer of the oil tank, i.e., the inner return oil pipe 3, allowing the return oil to flow a long distance to the suction chamber 202 under the action of the baffle. The tracked platform's motor and other components have the smallest return volume and carry the least heat. Therefore, its return oil outlet is located in the upper layer of the oil tank, i.e., the inner return oil pipe 2, allowing the return oil to flow from the upper layer to the lower layer of the suction chamber 202, extending the return oil flow path.

[0030] As a preferred embodiment, a shut-off valve 9 is installed on the first oil suction connection pipe; Both the second and third oil suction connection pipes are equipped with butterfly valves 10.

[0031] Further preferred, such as Figure 6 As shown, pressure sensors are installed at the input ends of the first pump, the second pump, and the third pump. A temperature and level sensor 13 is installed on the tank cover of the hydraulic oil tank 2; A mining multi-parameter oil quality sensor 14 is installed inside the groove 5 of the hydraulic oil tank 2.

[0032] As a preferred embodiment, the system also includes a controller, which is connected to the shut-off valve 9, each butterfly valve 10, the temperature and level sensor 13, the mining multi-parameter oil quality sensor 14, and each pressure sensor.

[0033] This method enables automatic control. The embedded hydraulic pump station mainly relies on pressure sensor groups, temperature and level sensors, and mining multi-parameter oil quality sensors to monitor and diagnose indicators such as hydraulic system pressure, oil tank hydraulic oil temperature, level, moisture, viscosity, wear particles, and contaminants in real time.

[0034] The embedded hydraulic pump station structure design and monitoring and diagnostic processing method adopted in this embodiment solves the modular layout problem of tracked automatic control drilling rigs in the limited space of the tracked vehicle platform, as well as the monitoring and diagnostic processing of hydraulic system pressure, oil temperature, level, and oil quality. This effectively shortens the length and width of the hydraulic pump station and improves the flexibility of the drilling rig's modular layout. The hydraulic oil tank integrates a pressure sensor group, temperature and level sensors, and a mining multi-parameter oil quality sensor to comprehensively monitor and diagnose the hydraulic system pressure and hydraulic oil. The data is processed automatically by the control system or manually, improving the service life of the drilling rig's hydraulic components and the level of intelligence in the drilling rig.

[0035] It is obvious that the above description and account are merely illustrative and not intended to limit the disclosure, application, or use of this invention. Although embodiments have been described and illustrated in the accompanying drawings, the invention is not limited to the specific examples exemplified by the drawings and described in the embodiments as currently considered the best mode for carrying out the teachings of the invention.
