[0026] Embodiment 1 As Figure 1 、 Figure 2 shown, a front vehicle assembly (hereinafter referred to as "front vehicle assembly") for a mine concrete wet shotcreting machine disclosed in this embodiment mainly includes a front frame 1, a boom system 2, a power system 3, a accelerator tank 4, and a hose pump 5.

[0027] The front frame 1 is an overall steel structure welded part. On the side plate at the first end, a plurality of ear plates are welded vertically as the front vehicle hinge frame 101 for articulating with the rear vehicle assembly by cooperating with a pin shaft. The boom system 2 is installed on the central axis at the top of the second end of the front frame 1 through a slewing bearing, that is, the boom system 2 can achieve a 360° slewing motion through the slewing bearing.

[0028] The power system 3 is arranged on the top of the front frame 1 and behind the boom system 2, and is mainly used to control operations such as the driving of the wet shotcreting machine and the lifting and lowering of the outriggers. Specifically, the power system 3 includes an engine, an air filter, and post-treatment equipment. The engine is fixed on the top of the front frame 1 through a mounting seat, and the mounting seat is provided with shock pads for shock absorption treatment. The air filter and the post-treatment equipment are installed on the covering parts of the engine nearby for quick maintenance operations.

[0029] The number of accelerator tanks 4 is two, and the two accelerator tanks 4 are respectively located on both sides of the power system 3. In this embodiment, two separate accelerator tanks 4 are used to store the accelerator, which can effectively reduce the volume of a single accelerator tank 4 and reduce the filling height of the accelerator on the premise that the storage capacity of the accelerator remains unchanged or even increases.

[0030] In the specific implementation process, the front vehicle assembly further includes a front wheel system 6. The front wheel system 6 includes two front wheels and two front fenders. The two front wheels are respectively installed on both sides of the front frame 1 through speed reducers, and the two front fenders are respectively fixedly connected to both sides of the front frame 1 through bolts and other fasteners and cover the front wheels on the corresponding side. Preferably, the two accelerator tanks 4 are respectively installed on the corresponding side of the front fender in a form fixed by bundling straps, so as to make full use of the installation space on the front frame 1, that is, increasing the number of accelerator tanks 4 makes the front vehicle assembly have a smaller width, enabling it to adapt to the size limitations of the mine cage and the passage in the narrow mine.

[0031] The hose pump 5 is located on the side of the power system 3 and is fixed to the left or right front fender through bolts and other fasteners. That is, the hose pump 5 is installed near the accelerator tank 4, and the hose pump 5 is connected to the accelerator tank 4 and the boom system 2 through pipelines, and is used to transport the accelerator to the nozzle on the boom system 2, and is sprayed together with the concrete spraying onto the support surface to achieve the effect of rapid setting.

[0032] Reference Figure 3 In addition, the front vehicle assembly further includes a front vehicle covering 7. The front vehicle covering 7 is fixedly connected to the front frame 1 through bolts and other fasteners, and the front vehicle covering 7 covers the power system 3 at the top and side to prevent external falling rocks, concrete and other sundries from falling into the power system 3. Preferably, a first support assembly 8 is provided on the front vehicle covering 7, such as a support welded to the top of the front vehicle covering 7, etc., so as to support the boom system 2 when it is retracted.

[0033] Embodiment 2 Reference Figure 1 、 Figure 2 In this embodiment, a mine concrete wet spraying machine (hereinafter referred to as "wet spraying machine") is disclosed, which mainly includes a rear vehicle assembly and the front vehicle assembly in Embodiment 1. The rear vehicle assembly includes a rear frame 9. On the vertical plate at the first end of the rear frame 9, multiple ear plates are welded as the rear vehicle hinge frame 901. The rear vehicle hinge frame 901 is hinged to the front vehicle hinge frame 101 through a pin shaft, and a steering cylinder is also hinged between the vertical plate at the first end of the rear frame 9 and the vertical plate at the first end of the front frame 1. By the telescopic movement of the steering cylinder, the change of the angle between the front frame 1 and the rear frame 9 can be realized, and thus the left and right steering of the whole vehicle can be controlled. In the specific application process, the steering angle of the whole vehicle can be adjusted by setting the distance between the ear plate hinge holes on the front frame 1 and the rear frame 9 and the corresponding vertical plates according to requirements.

[0034] In this embodiment, the rear frame 9 is integrally of two detachable sections, that is, the rear frame 9 includes a front section and a rear section. The front section and the rear section are assembled and fixed through connection structures such as flanges and bolts. That is, the wet spraying machine adopts a three-section assembled frame as a whole, so as to facilitate transportation in a mine cage with a small size and on-site assembly.

[0035] In this embodiment, the rear vehicle assembly further includes a cab 10, a hydraulic oil tank 11, an air compressor 12, a motor pump unit 13, a cable reel 14, an electric control cabinet 15, a pumping mechanism 16, a pumping pipeline 17, a hydraulic radiator 18, and a water tank 19.

[0036] The cab 10 is laterally mounted on the top of the first end and the first side of the rear frame 9 by means of bolt connection or welding, so that the driver sitting in the cab 10 can face the side of the wet shotcreting machine directly. Specifically, the cab 10 includes a cab skeleton, a seat, a steering and driving control mechanism. The cab skeleton is mounted on the top of the first end and the first side of the rear frame 9. There is a protective cover on the top of the cab skeleton. The seat is mounted inside and below the protective cover and close to the first side of the rear frame 9. The steering and driving control mechanism is located directly in front of the seat within the frame of the cab 10. Among them, the height of the seat is only slightly lower than that of the front frame 1, the front vehicle covering parts 7, and the rear vehicle covering parts 20, so that the driver's line of sight can observe the surroundings of the vehicle. Preferably, an armrest guardrail is mounted at one end of the cab skeleton facing the front frame 1 and corresponding to the outside of the seat to facilitate the driver's entry and exit, so that the cab 10 can improve the driver's comfort as much as possible under the condition of meeting the size limit of the wet shotcreting machine.

[0037] The hydraulic oil tank 11 is arranged on the top of the first end and the second side of the rear frame 9, so as to make full use of the remaining space at the first end of the rear frame 9. The air compressor 12 is arranged on the top of the rear frame 9 and behind the cab 10 and the hydraulic oil tank 11. The motor pump unit 13 is connected to the second side of the rear frame 9 through a support, and the motor pump unit 13 is located below the hydraulic oil tank 11 and the air compressor 12. Specifically, the side of the support is fixed to the rear frame 9 with high-strength bolts, and the motor pump unit 13 is mounted on the support through a shock pad, so as to protect the motor under high-frequency vibration. By mounting the motor pump unit 13 below the hydraulic oil tank 11, the bottom of the hydraulic oil tank 11 and the motor pump unit can be directly connected by a hydraulic oil pipe, the required oil pipe length is short, and the oil suction efficiency of the pump unit is high. At the same time, since the motor pump unit 13 is a high-heat-generating and frequently-maintained component, by mounting it on a separate support below the hydraulic oil tank 11 and the air compressor 12, there is sufficient heat dissipation space around it and it is convenient to maintain.

[0038] Specifically, the air compressor 12 includes an air compressor body 1201, a heavy-duty air filter 1202 and a fan 1203. The air compressor body 1201 is arranged on the top of the rear frame 9 and is located behind the cab 10 and the hydraulic oil tank 11. At the same time, the head and the tail of the air compressor body 1201 face the two sides of the rear frame 9 respectively, so that the air compressor body 1201 has sufficient heat dissipation space. The fan 1203 is arranged on the first side of the rear frame 9 and is located behind the air compressor body 1201, and the heavy-duty air filter 1202 is located behind the air compressor body 1201. The cable reel 14 is arranged on the first side of the rear frame 9 and is close to the second end of the rear frame 9, that is, the cable reel 14 is located behind the fan 1203. The electric control cabinet 15 is arranged on the second side of the rear frame 9 and is close to the second end of the rear frame 9, that is, the heavy-duty air filter 1202 is located between the fan 1203 and the electric control cabinet 15. The hydraulic radiator 18 is installed at the bottom of the cab 10, and the water tank 19 is installed on the rear frame 9 and is adjacent to the hydraulic radiator 18. In this embodiment, by optimizing the layout design of core components such as the air compressor 12 on the rear vehicle assembly, the problems of large transportation volume and poor adaptability to the mine environment of traditional equipment are effectively solved.

[0039] The pumping mechanism 16 is the main mechanism for controlling concrete spraying and determines the size of the spraying volume. In this embodiment, the pumping mechanism 16 is fixedly installed at the second end of the rear frame 9 through fasteners such as bolts. Its working cylinder extends forward from the inside of the rear frame 9 and is fixed on the front rib plate of the rear frame 9 through the pumping water tank 19. One end of the pumping pipeline 17 is connected to the pumping mechanism 16 through a pump pipe buckle, and the other end is connected to the boom system 2 for transporting concrete to the nozzle on the boom system 2.

[0040] In the specific implementation process, the rear vehicle assembly further includes a rear wheel system 21, and the rear wheel system 21 includes two rear wheels and two rear fenders. The two rear wheels are respectively installed on both sides of the rear frame 9 through reducers, and the two rear fenders are respectively fixedly connected to both sides of the rear frame 9 through fasteners such as bolts and cover the rear wheels on the corresponding side. The electric control cabinet 15 and the fan 1203 are respectively arranged on the rear fenders on the corresponding side, so as to make full use of the installation space on the rear frame 9 and make the rear vehicle assembly have a smaller width.

[0041] In this embodiment, there is a maintenance space for maintenance personnel to enter between the cable reel 14, the fan 1203, the heavy-duty air filter 1202, the electric control cabinet 15 and the pumping mechanism 16. Preferably, the cable reel 14 is rotatably connected to the rear frame 9 through a hinged rotating shaft, and a corresponding limiting device is provided on the reel mounting seat of the rear frame 9 to control the rotation angle of the cable reel 14. The gap extended by this angle can meet the needs of maintenance personnel to enter the middle of the wet shotcrete machine for operation. At the same time, the cable reel 14 is driven by a hydraulic motor to rotate itself, which is convenient for the retraction and release of the internal cable.

[0042] ReferenceFigure 4 The rear vehicle assembly further includes a rear vehicle covering member 20, which is fixedly installed on the rear vehicle frame 9 through fasteners such as bolts, and the rear vehicle covering member 20 covers the air compressor 12 and the electric control cabinet 15 at the top and the side, so as to prevent external sundries such as falling stones and concrete from falling into the power system 3.

[0043] In the specific implementation process, the pumping pipeline 17 includes a hard pipe assembly and a hose assembly. The first end of the hard pipe assembly is connected to the pumping mechanism 16, and the second end of the hard pipe assembly is located in front of the hydraulic oil tank 11 after passing above the rear vehicle covering member 20 and above the hydraulic oil tank 11. Preferably, a second support assembly 22 capable of supporting the hard pipe assembly, such as a support snap ring, etc., is provided on the rear vehicle covering member 20 and / or the hydraulic oil tank 11. The first end of the hose assembly is detachably connected to the second end of the hard pipe assembly, and the second end of the hose assembly is connected to the boom system 2. By making the overall direction of the pumping pipeline 17 above the vehicle, the overall width of the vehicle is reduced, the driving performance of the wet shotcreting machine is improved, and it is more suitable for operation in small alleyways.

[0044] Embodiment 3 This embodiment discloses a mine cage transportation method for the wet shotcreting machine in Embodiment 2, which is mainly divided into a first cage transportation method and a second cage transportation method. Among them, the first cage transportation method is mainly applicable to mine cages with larger sizes, such as the existing No. 6 cage. The second cage transportation method is mainly applicable to mine cages with smaller sizes, such as the existing No. 5 cage.

[0045] In the specific implementation process, the first cage transportation method includes the following steps: Step 101, disassemble the hinge structure between the rear vehicle hinge frame and the front vehicle hinge frame, and disassemble the oil circuit and the electric circuit between the front vehicle assembly and the rear vehicle assembly, and disassemble the flange device between the hard pipe assembly and the hose assembly; Step 102, disassemble the pumping mechanism, the pumping pipeline and the related oil circuit and electric circuit on the rear vehicle assembly; Step 103, place Figure 2 the overall front vehicle assembly as shown in Figure 5 the pumping mechanism as shown in Figure 6 the pumping pipeline as shown in Figure 7 and the remaining rear vehicle assembly as shown in four times and transport them to the first mine cage.

[0046] In the first cage transportation method, the boom system and the front vehicle frame are integrated for transportation, eliminating the need to separately disassemble the boom system. This avoids the disassembly of a large number of hydraulic fluid pipelines and electrical wiring harnesses between the boom system and the front vehicle frame, greatly reducing the time required for disassembly and assembly and ensuring the smooth progress of downhole operations. For the rear vehicle assembly part, only the pumping mechanism and the pumping pipeline need to be separately disassembled. The overall dimensions of the rear vehicle cover and other key components and the rear vehicle frame are smaller than the cage size, so they can be transported as a whole.

[0047] In the specific implementation process, the second cage transportation method includes the following steps: Step 201: Disassemble the hinge structure between the rear vehicle hinge frame and the front vehicle hinge frame, and disassemble the oil circuit and the circuit between the front vehicle assembly and the rear vehicle assembly, and remove the flange device between the rigid pipe assembly and the flexible pipe assembly; Step 202: Remove the front mudguards on both sides and the accelerator tank together from the front vehicle frame. At the same time, remove the front wheels, the reducer, the left and right outriggers, the hose pump, and the outrigger multi-way valve on the front vehicle frame. Transport the whole of the front mudguards and the accelerator tank, other disassembled structural parts, and Figure 8 the remaining front vehicle assembly shown to the second cage respectively; Step 203: Disassemble the rear vehicle cover, the motor pump unit, the electric control cabinet, the air compressor, the hydraulic oil tank, the rear wheels, and the reducer on the rear vehicle assembly. Remove one of the rear mudguards (the other rear mudguard is not removed). After disassembling the rear vehicle frame into two sections, transport each component including Figure 9 the front section of the rear vehicle frame shown to the second cage respectively.

[0048] In the second cage transportation method, based on the disassembly results of the first cage transportation method, the front vehicle assembly is further disassembled into three parts. The power system, the boom system, and the front vehicle frame form an integral whole, avoiding the removal of the engine mounts and the corresponding pipelines and reducing the corresponding disassembly and assembly time. The rear vehicle assembly is disassembled into several parts for separate packaging, aiming to meet the transportation requirements of using a smaller cage.

[0049] The above are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the protection scope of the present invention.
