The expressions "include", "contain", "have" and the like also mean "not limited to" (some units, components, materials, steps, etc.).

[0032] Reference Figures 1-8 The present application discloses a kind of tunneling working face shelf device, including multiple sequentially head-to-tail connection material storage unit 1, connection in material storage unit 1 and for driving multiple material storage unit 1 moves crawler traveling mechanism 2 and connection in material storage unit 1 and for providing power to crawler traveling mechanism 2 hydraulic drive mechanism 5, material storage unit 1 includes main frame 11, connection in main frame 11 and for storing material material rack 12, crawler traveling mechanism 2 and hydraulic drive mechanism 5 are all connected to main frame 11.

[0033] The material required by tunneling working face is placed on the material rack 12 of the material storage unit 1, and the crawler traveling mechanism 2 is driven by the hydraulic drive mechanism 5 to provide power, and drives the crawler traveling mechanism 2 to drive the whole movement of multiple material storage units 1. When the tunneling working face gradually advances forward, the crawler traveling mechanism 2 can move forward synchronously, so that the material is always kept in the area close to the tunneling working face, avoiding the problem of increasing the material transportation distance caused by fixed shelves. Through the operation of the device, the manual operation intensity in the material transfer process is greatly reduced, the human resources are saved, the safety risk caused by manual handling is reduced, and the work efficiency is improved.

[0034] The main frame 11 comprises a first main beam 111, a second main beam 117 and a plurality of first cross beams 112 connected between the first main beam 111 and the second main beam 117, and the material rack 12 comprises a bottom plate 121 connected between the first main beam 111 and the second main beam 117 and located at the top of the first main beam 111 and the second main beam 117, and a plurality of railings 122 connected to the bottom plate 121 and arranged circumferentially along the edge of the bottom plate 121;

[0035] The crawler traveling mechanism 2 comprises a plurality of crawler assemblies 21, two of which are connected to the first main beam 111 and the second main beam 117 respectively, and each of the crawler assemblies 21 comprises a load-bearing support connected to the first main beam 111 or the second main beam 117 and a first hydraulic motor (not shown in the figure) connected to the hydraulic drive mechanism 5.

[0036] The hydraulic drive mechanism 5 is a hydraulic station connected to the main frame 11 of any one of the plurality of material storage units 1.

[0037] The materials required for the tunneling working face are placed on the bottom plate 121 of the material rack 12, and the railings 122 on the edge of the bottom plate 121 can effectively prevent the materials from falling off the bottom plate 121 of the material rack 12 due to vibration or tilting during movement of the equipment. The hydraulic station provides power to the first hydraulic motor through the hydraulic pipeline, and the first hydraulic motor drives the crawler assembly 21 to move the main frame 11 and the material rack 12 together. When the equipment is running, the crawler assembly 21 bears the entire weight of the main frame 11 and the material rack 12, and at the same time provides sufficient traction to ensure that the device can run smoothly in the complex environment of the coal mine roadway.

[0038] It should be noted that the crawler assembly 21 and the load-bearing support are prior art. The crawler assembly 21 generally comprises a track plate, a drive wheel, a guide wheel, a supporting wheel and a tensioning device, etc., wherein the track plate is the main ground-engaging component that bears and distributes the overall weight of the equipment; the drive wheel is powered by the hydraulic motor to drive the track to run; the guide wheel is used to ensure that the running direction of the track does not deviate; the supporting wheel supports the weight of the main frame 11 and the track to ensure smooth running of the track; the tensioning device is used to adjust the tightness of the track to avoid faults caused by excessive looseness or tightness. The hydraulic station and the first hydraulic motor are also prior art, and their principles and application methods are known in the relevant field, and will not be described here.

[0039] In some embodiments, according to the design load of the material storage unit 1, the crawler assembly 21 can be arranged and installed in any of the plurality of material storage units 1, or in all of the material storage units 1.

[0040] The first main beam 111 and the second main beam 117 are further connected with a plurality of second cross beams 113, the first main beam 111 is connected with a plurality of first support plates 116 away from one side of the bottom plate 121, the second main beam 117 is connected with a plurality of second support plates 118 away from one side of the bottom plate 121, the plurality of first support plates 116 and the plurality of second support plates 118 correspond to each other, the second cross beam 113 is connected with a belt roller 114, and the first support plate 116 and the second support plate 118 are connected with a lower roller 115 matched with the belt roller 114.

[0041] The bottom plate 121 and the first main beam 111 and the bottom plate 121 and the second main beam 117 are connected with a plurality of support columns 123, so that the bottom plate 121 avoids the belt roller 114.

[0042] The plurality of belt rollers 114 and the plurality of lower rollers 115 of the plurality of material storage units 1 are matched and used for winding a coal conveying belt, the coal conveying belt is part of a belt conveyor and is integrated with the tunneling working face shelf device. In the running process, the belt roller 114 and the lower roller 115 are both passive rollers, and the belt conveyor provides power to drive the coal conveying belt to move in a cycle, so as to realize the conveying of mined coal. The plurality of support columns 123 separate the material rack 12 from the belt roller 114 and support the belt roller 114, so that the bottom plate 121 avoids interference in the structure position.

[0043] It should be noted that the belt roller 114 can adopt a three-roller arrangement, that is, each group of belt rollers 114 is composed of one horizontal roller and two inclined rollers, and the three rollers are rotatably connected to the second cross beam 113 through bearings. Among them, the horizontal roller is used to support the middle part of the coal conveying belt, and the two inclined rollers play a guiding role to prevent the belt from deviating during operation.

[0044] In some embodiments, the tunneling working face shelf device can be arranged in a belt lane.

[0045] In some embodiments, the main racks 11 of two adjacent material storage units 1 can be connected together through connecting seats.

[0046] In some embodiments, the load-bearing support is connected to the first main beam 111 or the second main beam 117 through a plurality of connecting shafts 22, the first cross beam 112 is connected with a first hydraulic cylinder (not shown in the figure) for driving the connecting shaft 22 to move in a direction perpendicular to the first main beam 111 or the second main beam 117; the first main beam 111 and the second main beam 117 are respectively connected with a second hydraulic cylinder 61, and the output shafts of the two second hydraulic cylinders 61 are connected with a support plate 6 for lifting the track assembly 21 to separate from the ground.

[0047] When the moving direction of the tunneling working face rack device needs to be adjusted during movement, first, the two second hydraulic cylinders 61 drive the support plate 6 to support the ground, lift the material storage unit 1 and its track assembly 21, and make the track assembly 21 separate from the ground. At this time, the track assembly 21 is no longer in contact with the ground, and the angle adjustment can be performed without load. Subsequently, the first hydraulic cylinder drives the connecting shaft 22 to reciprocate in a direction perpendicular to the first main beam 111 or the second main beam 117, driving the load-bearing support and the track assembly 21 to displace in the direction, thereby achieving the deflection angle adjustment of the track assembly 21. Through the set deflection range, the moving direction of the tunneling working face rack device can be adjusted.

[0048] It should be noted that the number of support plates 6 and second hydraulic cylinders 61 can be set according to actual needs, and the purpose is to ensure that all track assemblies 21 are lifted and their deflection angles are adjusted.

[0049] The main frame 11 is connected with a lifting mechanism 3 for lifting materials to the bottom plate 121, the lifting mechanism 3 includes a stand 31 connected to the first main beam 111, a lifting rod 32 connected to one end of the stand 31, a winch 33 connected to one end of the lifting rod 32, a hook 34 located at the other end of the lifting rod 32 and connected with the lifting rope of the winch 33, and a second hydraulic motor 35 connected between the stand 31 and the lifting rod 32 and used to drive the stand 31 to rotate around the central axis of the stand 31, the stand 31 is located outside the bottom plate 121.

[0050] The second hydraulic motor 35 drives the lifting rod 32 to rotate around the central axis of the stand 31, adjusts the lifting rod 32 to the stacking or unloading position of the materials, at this time, the winch 33 controls the extension and retraction of the lifting rope, and drives the hook 34 to lift the materials to be lifted from the ground. Subsequently, the second hydraulic motor 35 drives the lifting rod 32 to rotate again, lifts the materials to the top position of the material rack 12, and finally, the winch 33 accurately controls the length of the lifting rope and the position of the hook 34, slowly lifts the materials to the bottom plate 121, and completes the lifting and loading operation of the materials.

[0051] It should be noted that the winch 33 and the hook 34 are prior art.

[0052] In some embodiments, the first hydraulic cylinder, the second hydraulic cylinder 61, the first hydraulic motor, the second hydraulic motor 35 and the winch 33 can be connected to the hydraulic station through the hydraulic pipeline, and the hydraulic station provides power for them. The hydraulic pipeline is connected by high-strength pressure-resistant hose or steel oil pipe, and each component is provided with a control valve at the hydraulic input end to ensure the stability and reliability of the hydraulic system. In addition, the hydraulic station can be equipped with a pressure regulating valve and a flow control device, which can provide the required power according to the needs of different components.

[0053] Meanwhile, the first hydraulic cylinder, the second hydraulic cylinder 61, the first hydraulic motor, the second hydraulic motor 35 and the winch 33 can also be operated by remote control. The remote control can adopt a wireless signal control system, which includes a wireless remote control and a hydraulic station control module. The operator sends control instructions through the wireless remote control, the wireless signal receiving device transmits the instructions to the control module of the hydraulic station, and then the control module controls each component in the hydraulic system through electromagnetic valves or servo valves. The remote control can be provided with multiple function buttons, including lifting, rotating, tensioning and other operation instructions, and is equipped with a liquid crystal screen to display the running state of the equipment in real time, so as to facilitate the operator to monitor the working condition of the equipment at any time.

[0054] In some embodiments, the hoisting mechanism 3 is additionally provided with an electronic fence device, a warning light and a voice prompt in its hoisting range.

[0055] The support column 123 connected to the second main beam 117 is connected with the U-shaped hook 4.

[0056] The U-shaped hooks 4 arranged on the plurality of support columns 123 connected to the second main beam 117 can be used to place long tools or materials, such as long anchor rods, steel pipes and long steel belts. These U-shaped hooks 4 are designed in an open structure, which can conveniently hang long tools or materials thereon, avoiding the problem of random stacking or scattering of materials.

[0057] The first main beam 111 and the second main beam 117 are both connected with the sliding shoe 7 supported on the ground.

[0058] The sliding shoe 7 keeps in contact with the ground during the movement of the support device on the tunneling working face, providing additional support force. The design of the sliding shoe 7 enables it to smoothly slide when the device moves as a whole, thereby effectively dispersing the pressure of the device on the ground and reducing the damage of single-point force to the ground.

[0059] The working mechanism of the sliding shoe 7 is to reduce the frictional resistance with the ground through its smooth bottom structure, ensuring the smooth operation of the support device on the tunneling working face during movement. Especially in the case of uneven ground or large load in the tunnel, the sliding shoe 7 can effectively prevent the device from tilting or shaking, thereby protecting the safety of the device and the materials.

[0060] It should be noted that the sliding shoe 7 is a prior art, which will not be described herein.
