Multi-condition pneumatic self-moving roadway transportation system and method

[0001] Cross-reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 202410522804.1 filed on April 28, 2024 with the State Intellectual Property Office of China and entitled "Multi-condition pneumatic self-moving roadway transportation system and method", the entire contents of which are incorporated herein by reference and form a part of the present application and are used for all purposes. TECHNICAL FIELD

[0003] The present application relates to the technical field of mine roadway transportation, in particular to a multi-condition pneumatic self-moving roadway transportation system and a transportation method using the system in a roadway. BACKGROUND

[0004] In recent years, steel pipe concrete support has been widely developed in coal mines due to its excellent cost performance and high bearing capacity. The steel pipe concrete support is transported from the ground to the storage place of supporting materials in the underground and is stored centrally. The distance from the installation support construction site is usually about 100 meters. Since the roadway is just excavated, the supporting materials are scattered on the ground from the material storage place to the construction site, and the ground walking transport vehicles cannot pass through, so the 100-meter steel pipe concrete support can only be manually transported to the working face at present.

[0005] At present, the commonly used types of steel pipe concrete support include Ф194x8, Ф194x10, Ф219x8, and Ф219x10. Due to the different sizes and shapes of the roadway cross section, the weight of the steel pipe concrete support is also different. Generally, the weight of the empty steel pipe concrete support is more than 1 ton per support, and the highest can be up to 2 tons per support. At present, manually transporting the empty steel pipe support from the storage place to the working face not only has high labor intensity, high risk, and poor working environment, but also has low efficiency. Considering the above factors, the manual transportation from the storage place to the working face seriously affects the production efficiency and directly threatens personal safety. In addition, due to the limited space of the coal mine roadway and the rugged and uneven ground of the just-excavated roadway, the supporting materials are scattered on the ground, so large ground mechanical equipment cannot be used.

[0043] A rack 18 is arranged on the stepping mechanical hand spacing adjustment device 5, the rack 18 being engaged with a gear 4, the gear 4 being installed on the connecting frame 17, the gear 4 being driven to rotate by a driving device, when the gear 4 rotates, the stepping mechanical hand spacing adjustment device 5 can be driven to move forward or backward with the pneumatic stepping mechanical hand 2-1 and the pneumatic stepping mechanical hand 2-2; a mechanical hand extension oil cylinder 3-2 is installed on the top of the connecting frame 17, the mechanical hand extension oil cylinder 3-2 driving a pneumatic locking mechanical hand 1.

[0044] It should be noted that the connecting frame 17, the pneumatic locking mechanical hand 1, the hydraulic rod 7, the rotating disc 8, the support frame 15, the extendable wheel 9, the extension rod 11 and the moving balance wheel 16 are an integral whole and can move together; the stepping mechanical hand spacing adjustment device 5, the rack 18, the mechanical hand extension oil cylinder 3-1, the mechanical hand extension oil cylinder 3-3, the pneumatic stepping mechanical hand 2-1 and the pneumatic stepping mechanical hand 2-2 are an integral whole and can move together.

[0045] Further, a pneumatic transmission pulley 10 is installed on the side of the support frame of the first and second transportation mechanisms, and the two pneumatic transmission pulleys are connected by a steel cable 12.

[0046] Further, a telescopic wheel 9 is installed on the support frame, and the telescopic wheel 9 can be extended outside the support frame when needed, as shown in FIG. 2, and the telescopic wheel 9 drives the transportation mechanism to move together with the moving balance wheel.

[0047] Further, the support frame is rotationally connected with the rotating connecting rod 11, that is, the support frame can rotate relative to the rotating connecting rod 11, as shown in FIG. 1 and FIG. 2, and the support frame can be rotated to the top of the rotating connecting rod 11 (as shown in FIG. 1) or to the side of the rotating connecting rod 11 (as shown in FIG. 2).

[0049] Further, the bottom of the connecting frame 17 is connected with the hydraulic rod 7 through the rotating joint 6, so that the connecting frame 17 can rotate by a certain angle with the pneumatic stepping manipulator 2-1, the pneumatic stepping manipulator 2-2 and the pneumatic locking manipulator 1 on it, so as to adapt to the third working condition, that is, the working condition when the mechanical equipment needs to pass through the middle of the roadway.

[0050] Based on the above transportation system, the application also provides a specific transportation method of the above transportation system under different working conditions, and the transportation method is as follows:

[0051] (1) The working condition when the material transportation is carried out in the roadway in which the support has been completed

[0052] Since the roadway in this working condition has been supported, and the ground of the roadway is free of sundries, only one of the transportation mechanisms needs to be used to realize the transportation of the materials, as shown in FIG. 2, in this working condition, the support frame 15 is rotated by 90 degrees relative to the telescopic rod 11, the telescopic wheel 9 is extended, and then the pneumatic locking manipulator 1 and the pneumatic stepping manipulators 2-1 and 2-2 are parallel to the ground, the manipulator grasps the steel pipe concrete support, and the transportation of the materials is realized, as shown in FIG. 2, and in this process, the angle of the pneumatic locking manipulator 1 and the pneumatic stepping manipulators 2-1 and 2-2 can be adjusted through the rotation of the manipulator rotating disc 8.

[0053] (2) The working condition when there are sundries between the material storage place and the construction surface

[0054] In this working condition, the first support transport mechanism and the second support transport mechanism need to cooperate to complete the entire work. The telescopic wheels 9 of the two support transport mechanisms are retracted, the telescopic rods 11 are vertically located at the bottom of the support frame, the mechanical hand telescopic oil cylinders 3-1, 3-2, and 3-3 are extended (Fig. 3), the pneumatic locking mechanical hand 1 and the pneumatic stepping mechanical hands 2-1 and 2-2 are clamped to the installed steel pipe concrete support to complete the fixing; the steel cable 12 passes through the pulleys 10 on the first support transport mechanism and the second support transport mechanism to form a closed ring, the support transport frame 14 is fixed at a position on the upper end steel cable (increasing the ground clearance of the transport frame to ensure that it does not touch the bottom sundries during transportation) through the steel cable clamp 13, ensuring that the support transport frame and the steel cable do not move relative to each other, and the steel cable tightener is installed at the lower end of the steel cable. By adjusting the tension of the steel cable, it is ensured that the transport steel cable always remains tight after being stressed. Fig. 4 is a schematic diagram of the pneumatic roadway transport system after installation.

[0055] When a steel pipe concrete support is installed, the pneumatic stepping mechanical hands 2-1 and 2-2 are loosened and retracted through the hydraulic cylinder to realize the descent; the pneumatic locking mechanical hand 1 remains clamped. The pneumatic stepping mechanical hands 2-1 and 2-2 are moved forward by one steel pipe concrete support through gear and rack transmission, and then clamped, and then the pneumatic locking mechanical hand 1 is loosened, and then moved forward through gear and rack transmission, that is, the entire device is moved forward.

[0056] The support transport frame can transport 4 steel pipe concrete supports (or other support materials) at a time. The relative height of the pneumatic hydraulic telescopic support frame can be controlled to utilize the gravity of the transported materials to provide part of the transport force, thereby reducing energy consumption. The pneumatic transmission pulley 10 is used to control the moving speed of the transport frame and realize braking. When transporting the support from the material storage place to the working surface, the first support transport mechanism is raised in height, the right side and the second support transport mechanism are lowered in height, and the support transport frame 14 can realize the transportation of materials to the working surface.

[0057] The telescopic rod 11 of the left first support transport mechanism is lowered in height, and the telescopic rod 11 of the right second support transport mechanism is raised in height, so that the transport frame can move from the working surface to the material storage place, and thus the material transportation in the roadway can be realized.

[0058] When the first and second support transport mechanisms cannot create a height difference or the material transportation section has a high terrain, only the pneumatic motor can be used to drive the pneumatic transmission pulley 10 to transport materials.

[0059] (3) The working condition when mechanical equipment needs to pass through the middle of the roadway

[0060] The mechanical arm rotating disc 8 drives the hydraulic rod 7 above it, so that the pneumatic mechanical arm 1 is perpendicular to the side steel pipe concrete support. The pneumatic mechanical arm 1 is elongated to grab the steel pipe concrete support (as shown in FIG. 5), the fixing of the conveyor is completed, and then a closed ring is formed by a steel cable passing through the pulleys of a set of pneumatic hydraulic telescopic support frames, the support transport frame is fixed at a position of the upper end steel cable (the ground distance of the transport frame is increased to ensure that the bottom sundries are not touched during the transportation process), the support transport frame and the steel cable are prevented from moving relative to each other, the steel cable tightener is installed at the lower end of the steel cable, the tension of the steel cable is adjusted, and the steel cable is kept in a tight state after being stressed. After a set of steel pipe concrete supports are installed, the self-moving mode in (2) can still be used for advancing.

[0061] The hydraulic cylinders and transmission pulleys of the device are all powered by pneumatic motors, and after the pneumatic hydraulic telescopic support frame is completely retracted, the height is 3 meters and the width is 2 meters, which is convenient for transportation. The transportation distance between the devices can be determined according to the on-site construction condition by controlling the distance of a set of pneumatic hydraulic telescopic support frames, and only the length of the steel cable needs to be increased.

[0062] Finally, it should be noted that the relational terms such as first and second are used only to distinguish one entity or action from another, and do not necessarily require or imply that these entities or actions exist in any such actual relationship or order.

[0063] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
