Detailed Implementation

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following is a reference to the appendix. Figure 1 and Figure 2 This invention provides a detailed description of the downhole spraying support material spraying equipment 100 and its usage method according to an embodiment of the present invention.

[0022] The downhole support material spraying equipment 100 includes a vehicle body 1, a spray material tank 2, a first pump 3, a flushing material tank 4, a second pump 7, and a spray gun assembly 5. The vehicle body 1 has an installation platform 11. The spray material tank 2 and the first pump 3 are mounted on the installation platform 11. The spray material tank 2 stores the spray material, and the inlet of the first pump 3 is connected to the spray material tank 2. The flushing material tank 4 and the second pump 7 are mounted on the installation platform 11. The flushing material tank 4 stores the flushing fluid, and the inlet of the second pump 7 is connected to the flushing material tank 4. The spray gun assembly 5 includes a spray gun and a spray gun valve assembly 52. ​​The outlets of the first pump 3 and the second pump 7 are both connected to the spray gun valve assembly 52, and the spray gun valve assembly 52 is connected to the spray gun 51.

[0023] The method of using the downhole spraying support material spraying equipment of this utility model embodiment involves using the downhole spraying support material spraying equipment 100 of this utility model embodiment. Before operation, the spraying material tank 2 is filled with thin-spray material, and the flushing material tank 7 is filled with flushing fluid. The operating vehicle 1 is moved to the designated position, and the first pump 3 and the second pump 7 are turned on. The first pump 3 pumps the spraying material in the spraying material tank 2 toward the spray gun 51, and the second pump 7 pumps the flushing fluid in the flushing material tank 4 toward the spray gun 51. The operating spray gun valve group 52 controls the connection between the first pump 3 and the spray gun 51, and the spray gun 51 is turned on to carry out the thin-spray material spraying operation. At this time, the flushing fluid is blocked by the spray gun valve group 52 and temporarily stored in the pipeline. After the spraying operation is completed, turn off the first pump 3 to stop pumping the thin spray material to the spray gun 51. Then operate the spray gun valve group 52 to disconnect the first pump 3 from the spray gun 51 and connect the second pump 7 to the spray gun 51, so that the flushing liquid temporarily stored in the pipeline is discharged through the spray gun valve group 52 and the spray gun 51 to perform the flushing operation. After the flushing is completed, turn off the second pump 7 and the spray gun 51.

[0024] The downhole spraying support material spraying equipment 100 of this utility model embodiment can be moved to a designated construction position by operating the vehicle body 1. The first pump 3 connects the spraying material tank 2 and the spray gun assembly 5, which can pump the thin spraying material to the spray gun. The second pump 7 connects the flushing material tank 4 and the spray gun assembly 5, which can pump the flushing fluid to the spray gun. The thin spraying material and the flushing fluid are sprayed separately by controlling the spray gun valve group 52. The thin spraying material is sprayed, and the spray gun and local pipelines are flushed after spraying to prevent the thin spraying material from accumulating on the pipeline from the spray gun valve group 52 to the spray gun 51 and on the spray gun 51, thus ensuring the reusability of the spray gun 51.

[0025] Therefore, the underground spraying support material spraying equipment 100 of this utility model embodiment can achieve the spraying of polymer materials and realize the construction of thin-spray support. Furthermore, the underground spraying support material spraying equipment 100 of this utility model embodiment has a simple structure and can be miniaturized, thus enabling it to move through working environments with limited space, adapting to different coal mine scenarios, and achieving convenient construction.

[0026] In some embodiments, the vehicle body 1 includes a tracked chassis 13 and a drive control assembly 12. The tracked chassis 13 has a mounting platform 11, and the drive control assembly 12 is mounted on the mounting platform 11 and connected to the tracked chassis 13. The vehicle body 1, using a tracked chassis 13, has a large ground contact area, high friction with the ground, and good grip, making it suitable for various complex terrains and further improving the passability of the downhole spraying support material spraying equipment 100 of this embodiment.

[0027] In some embodiments, the tracked chassis 13 is a hydraulically driven tracked chassis 13. Specifically, the tracked chassis 13 is a hydraulically driven dual-track chassis.

[0028] The drive control assembly 12 includes an electrical control box 121, a hydraulic pump station 122, and a first hydraulic valve 123. The electrical control box 121 is connected to the hydraulic pump station 122, which has a first output pipeline (not shown in the figure). The first output pipeline is equipped with the first hydraulic valve 123 and is connected to the tracked chassis 13. The electrical control box 121 provides power to the hydraulic pump station 122 and controls its start and stop. The first hydraulic valve 123 controls the opening and closing of the first output pipeline, thereby controlling the movement of the tracked chassis 13.

[0029] Personnel control the start and stop of the hydraulic pump station 122 by operating the electrical control box 121, and control the movement and stop of the tracked chassis 13 by operating the first hydraulic valve 123.

[0030] In some embodiments, the hydraulic pump station 122 has a second output pipeline (not shown). The vehicle body 1 further includes a support cylinder 14 and a second hydraulic valve 124. There are multiple support cylinders 14, which are spaced apart at the edge of the tracked chassis 13. The support cylinders 14 are connected to the second output pipeline, and the second output pipeline is provided with the second hydraulic valve 124, which controls the opening and closing of the second output pipeline.

[0031] When using the downhole spraying support material spraying equipment 100 of this utility model embodiment for construction, after the vehicle body 1 moves to the designated construction position, the second hydraulic valve 124 is operated to connect the second output pipeline, controlling the extension of multiple support cylinders 14 to support the ground, thereby fixing the vehicle body 1 and fixing the spraying equipment 100 in the designated position, thereby improving the stability and safety of the downhole spraying support material spraying equipment 100 of this utility model embodiment during spraying construction.

[0032] Specifically, there are four support cylinders 14, which are located at the four corners of the tracked chassis 13.

[0033] In some embodiments, the spray material box 2 includes a box body 21 and a mixer 22. The box body 21 is mounted on the mounting platform 11, and the mixer 22 is mounted on the box body 21 to mix the thin spray material inside the box body 21. During construction, before turning on the first pump 3, the mixer 22 is turned on. The mixer 22 mixes the thin spray material inside the box body 21, improving the fluidity of the thin spray material and preventing it from becoming viscous. This improves the smoothness of the flow path of the thin spray material from the box body 21 to the spray gun, ensuring the spraying effect of the downhole spray support material spraying equipment 100 of this embodiment on the thin spray material.

[0034] Specifically, the hydraulic pump station 122 has a third output pipeline (not shown in the figure), and the vehicle body 1 further includes a third hydraulic valve 125. The mixer 22 includes a hydraulic motor and a mixing shaft (not shown in the figure). The hydraulic motor is mounted on the housing 21 and connected to the third output pipeline. The third output pipeline is equipped with the third hydraulic valve 125, and the mixing shaft is mounted on the output shaft of the hydraulic motor. During construction, after the hydraulic pump station 122 is turned on, the third hydraulic valve 125 is operated to control the connection of the third output pipeline, thereby controlling the start of the hydraulic motor, which drives the mixing shaft to mix the thin sprayed material in the housing 21. The mixer 22 uses a hydraulic motor, which is easily connected through the drive control component 12 of the vehicle body 1, and is powered by the hydraulic pump station 122 and controlled to start and stop by the third hydraulic valve 125.

[0035] In some embodiments, the housing 21 is a heated and insulated housing with heating and insulation properties, which helps to ensure that the thin-sprayed material is in a suitable temperature environment, ensures that the thin-sprayed material is in a suitable temperature, ensures the performance of the thin-sprayed material, and ensures that the performance of the thin-sprayed material is in good condition, thereby ensuring the effect of the thin-sprayed material.

[0036] Specifically, such as Figure 2 As shown, the first hydraulic valve 123, the second hydraulic valve 124, and the third hydraulic valve 125 are arranged side by side to form a hydraulic valve group. The hydraulic valve group is located at one end of the mounting platform 11 in the first direction. The hydraulic pump station 122 and the electrical control box 121 are adjacent to the hydraulic valve group. The hydraulic pump station 122 and the electrical control box 121 are arranged at intervals in the second direction, which is perpendicular to the first direction and parallel to the axial direction of the track wheels of the tracked chassis 13. The flushing material tank 4 and the second pump 7 are opposite each other in the second direction. In the first direction, the spraying material tank 2 is located between the flushing material tank 4 and the hydraulic pump station 122, and the first pump 3 is located between the second pump 7 and the electrical control box 121. The first direction is the same as the front-back direction, and the second direction is the same as the left-right direction.

[0037] The hydraulic valve assembly is located at the front end of the installation platform 11. The hydraulic pump station 122 and the electrical control box 121 are arranged at intervals on the left and right sides. The hydraulic pump station 122 is located behind the hydraulic valve assembly. The flushing material box 4 and the second pump 7 are arranged on the left and right sides. The spraying material box 2 is adjacent to the hydraulic pump station 122. This arrangement makes the hydraulic valve assembly and the spraying material box 2 close to the hydraulic pump station 122, which makes the equipment layout on the installation platform 11 compact and facilitates the setting of the first output pipeline, the second output pipeline and the third output pipeline. It optimizes the layout path of the output pipeline and helps to reduce the area of ​​the required installation platform 11, thereby helping to reduce the volume of the downhole spraying support material spraying equipment 100 of this utility model embodiment and helping to improve the miniaturization and throughput performance of the downhole spraying support material spraying equipment 100 of this utility model embodiment.

[0038] Specifically, the downhole spraying support material spraying equipment 100 of this utility model further includes a mounting frame 6. The first pump 3 and the second pump 7 are mounted on the mounting platform 11 via the mounting frame 6. The first pump 3 and the second pump 7 are spaced apart from the mounting platform 11. The mounting frame 6 is connected to the flushing material tank 4. The mounting frame 6 is set up based on the flushing material tank 4, which makes full use of the large volume of the flushing material tank 4. It can ensure the stability of the mounting frame 6 in supporting the first pump 3 and the second pump 7, and also facilitates the installation and layout of the pipelines of the first pump 3 and the second pump 7, thereby improving the stability and safety of the downhole spraying support material spraying equipment 100 of this utility model embodiment.

[0039] The spray gun valve assembly 52 has a first inlet, a second inlet, and an outlet. The spray gun assembly 5 further includes a first pipe 53, a second pipe 54, and a third pipe 55. The first pipe 53 connects the outlet of the first pump 3 and the first inlet; the second pipe 54 connects the outlet of the second pump 7 and the second inlet; and the third pipe 55 connects the outlet and the inlet of the spray gun. During construction, the spray gun valve assembly 52 is operated to connect the first pipe 53 and the third pipe 55, connecting the first pump 3 to the spray gun. After the spray gun is turned on, the thin-layer spraying operation of the material can be performed. After the spraying operation is completed, the first pump 3 is turned off, and the spray gun valve assembly 52 is operated to disconnect the first pipe 53 and the third pipe 55 and connect the second pipe 54 and the third pipe 55, allowing the rinsing liquid to flow through the third pipe 55 and then be discharged from the spray gun, thus achieving the rinsing of the third pipe 55 and the spray gun.
