Description

Technical Field

[0001] The present invention relates to the technical field of coal mine machinery and mining equipment, and in particular to a coal mine conveyor belt cutting integrated buckle nailing device and method. Background Art

[0002] Coal mine conveyor belts are critical equipment for coal production and transportation. Their operational continuity and stability directly impact mine production efficiency and safety. However, belts are prone to tearing, wear, and joint breakage over long periods of operation, necessitating repair or replacement. Currently, belt repair primarily involves manual repair and semi-automated repair.

[0003] Most coal mines still rely on manual cutting and nailing operations, using hand tools and mechanical nailing machines, which have low repair efficiency. A single joint usually takes a long time, and the operation accuracy depends on the workers' experience, making it difficult to ensure consistency. For local damage, cold vulcanization or hot vulcanization bonding technology is usually used for repair, but this method has a long downtime, generally taking 2 to 4 hours, and the bonding strength is greatly affected by the ambient temperature and humidity. Some large mines have introduced hydraulic or electric nailing machines, which can significantly shorten the repair time of a single joint, but the overall equipment is relatively bulky, and has high requirements for the alignment of the belt and the nails, and needs to be used with positioning fixtures.

[0004] Current traditional repair methods have numerous shortcomings. Uneven manual cutting or uneven nailing force can lead to stress concentration in the joint, increasing the risk of secondary fracture. Work often takes place along narrow conveyor lines, making accidents like mechanical pinching and belt slippage more likely. Furthermore, existing repair methods rely primarily on manual labor, resulting in high labor intensity, harsh working environments, and low repair efficiency. Therefore, more efficient and intelligent repair technologies are urgently needed to improve operational safety and reliability. Summary of the Invention

[0045] The present application also provides a method for cutting and fastening integrated belts for a coal mine conveyor, comprising the following steps:

[0046] S1. Equipment positioning stage:

[0047] The integrated equipment is placed on the side of the belt conveyor, and the horizontal height of the lifting platform is adjusted by the lifting cylinder in the vertical adjustment mechanism so that it can pass under the belt and reach under the belt area to be cut, so as to lift the area;

[0048] S2. Highly adapted stage:

[0049] The rear support cylinder group is extended. When the rear support plate hits the rear tunnel side wall, the thrust generated by the rear support cylinder group will push the equipment forward. At the same time, the front support cylinder group is adjusted synchronously so that the front support plate hits the front tunnel side wall.

[0050] When the lifting platform reaches the predetermined position, the front and rear support cylinder groups stop moving and lock each support cylinder, providing a stable support for the equipment through a four-point positioning method with the side wall of the roadway;

[0051] S3. Belt cutting operation:

[0052] Adjust the lifting cylinder so that the lifting platform in the middle lifts up the belt area to be cut;

[0053] Adjust the cutting pitch adjustment cylinder to adjust the cutting boom to a horizontal posture. At the same time, the cutting boom and the lifting platform can clamp the belt. Start the cutting drive motor to rotate the cutting tool. Then start the sliding drive motor I to move the two cutting execution units as a whole along the cutting operation slide rail to achieve segmented and smooth cutting of the belt.

[0054] After the cutting operation is completed, adjust the cutting pitch adjustment cylinder to adjust the cutting boom to a vertical posture;

[0055] S4. Belt roll lifting operation:

[0056] The lifting device lifts the belt reel through the rope, and the pitch telescopic cylinder extends, so that the telescopic arm is raised and extended synchronously;

[0057] After reaching the predetermined height, the hydraulic rotating base starts to move, so that the belt roll reaches the height of the cutting and lifting platform. At this time, the belt roll can be placed above the belt conveyor;

[0058] Pull out a suitable length of belt from the belt roll as the belt to be replaced, and cut it at a predetermined position using a cutting execution unit;

[0059] S5. Belt buckle sewing operation:

[0060] Adjust the pitch adjustment cylinder of the button fastener to adjust the button fastener cantilever to a horizontal posture;

[0061] Pass the original belt cut ends on the belt conveyor and the two end interfaces of the belt to be replaced through the gap under the belt pressing plate respectively, and drive the pressing plate to drive the oil cylinder to make the belt pressing plate clamp the belt to be fastened;

[0062] After the button set is placed, the punching mechanism is started and a load is applied downwards to complete a buttoning action;

[0063] After that, the sliding drive motor II is activated to move the button sewing unit as a whole along the button sewing operation slide rail for the distance of one button sewing, and then repeats the button sewing and horizontal movement until the button sewing operation of the entire belt cut is completed;

[0064] After the button fastening operation is completed, each mechanism returns to its initial position, and the button fastening pitch adjustment cylinder is adjusted to adjust the button fastening cantilever to a vertical posture;

[0065] S6. System reset stage: After the operation is completed, the front support cylinder group extends and the rear support cylinder group shortens, so that the machine is withdrawn from the working area, and each device is restored to its initial state and moved as a whole.

[0066] S7. Belt connection stage:

[0067] Replace the cut vacant position on the original belt with the belt to be replaced;

[0068] Use the connecting pin to connect the belt to be replaced with the buckle at the cut end of the original belt to complete the repair of the damaged area of the belt.

[0069] Compared with the prior art, the present invention has the following beneficial effects:

[0070] 1. The coal mine conveyor belt cutting and buckling integrated buckle-stitching equipment provided in this application integrates core functions such as belt cutting, buckling, and lifting through a liftable and foldable mechanical structure. Specifically, the cutting execution unit and buckling execution unit in the composite operation mechanism have clear divisions of labor, enabling rapid connection between cutting and buckling operations; the material transfer mechanism in the material transfer mechanism can complete the transfer and lifting of the belt roll. This integrated design significantly reduces the number of equipment and floor space, effectively improving operational efficiency and reducing equipment deployment costs in the limited space environment of underground coal mines.

[0071] 2. The cutting and buttoning units can select the appropriate cutting speed and tool rotation speed based on the belt material, thickness, width, and other parameters. The vertical adjustment mechanism can adjust the height of the cutting and buttoning units and the position of the lifting platform to ensure operational accuracy, reduce manual operation difficulty, and improve the level of automation.

[0072] 3. The bottom support device of the equipment in this application features a non-slip and wear-resistant end support unit, which enables autonomous movement and secure fixation. Before operation, the rear support cylinder group can be used to push the machine base under the belt conveyor, and then the front support cylinder group can be used to coordinate and extend to quickly secure the machine body. After the operation is completed, the front support cylinder group can safely push the machine out of the work area. The entire process is simple to operate, significantly reducing equipment preparation and evacuation time.

[0073] 4. The equipment utilizes a four-step workflow: "positioning - adjustment - operation - reset." First, the equipment is positioned using a support mechanism. The angles and heights of the cutting and buttoning arms in the composite operating mechanism are then adjusted according to the belt parameters. The cutting and buttoning actuators then coordinate according to a pre-set program, and finally, all actuators automatically reset. Compared to traditional processes, this equipment shortens the time required for belt breaking and reconnection, reducing safety risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0097] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0098] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0099] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this disclosure, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0100] Moreover, the technical solutions between the various embodiments of the present invention may be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0101] As attached Figure 1 -Attached Figure 2 As shown, the technical problem to be solved by the present invention is to overcome the above technical defects and provide a coal mine conveyor belt cutting integrated buckle nailing equipment. The equipment adopts an integrated intelligent design, integrating belt cutting, buckle nailing, lifting and other functions into one, significantly improving the efficiency and safety of underground coal mine belt repair operations.

[0102] Its main structure includes: a base plate 1, which serves as the base of the equipment and provides support and installation foundation for the entire equipment; a support device 2, which includes a front support cylinder group 2-1, a rear support cylinder group 2-2 and an angle adaptive component. The support device 2 can not only realize the flexible forward and backward movement of the equipment in the tunnel, so that the equipment can quickly reach the designated working position, but also provide stable and reliable support for the equipment after reaching the designated position, ensuring stability during operation.

[0103] The vertical adjustment mechanism 3 is rigidly connected to the base plate 1 at its bottom and supports the lifting platform 4-1 at its top. Through this vertical adjustment mechanism 3, the vertical height of the lifting platform 4-1 can be precisely adjusted to accommodate belt operations at different heights and positions. The composite operation mechanism is the core functional part of this equipment and includes two sets of cutting execution units 4 integrated on the lifting platform 4-1 and fastening execution units 5 distributed on both sides of the lifting platform 4-1. The two sets of cutting execution units 4 are respectively used to precisely cut the front and rear ends of the belt area to be cut, ensuring the accuracy and smoothness of the cut; the fastening execution units 5 on both sides are respectively used to firmly fasten the two ends of the replacement belt to the front and rear ends of the belt cut, achieving rapid connection of the belt.

[0104] The material transfer mechanism 6 is primarily used to transfer the belt roll 8 to the upper portion of the lifting platform 4-1, providing a convenient material supply for belt replacement. The power supply mechanism includes an integrated hydraulic pump station 7, which, through a multi-way valve block, provides stable and reliable hydraulic power to the support device 2, vertical adjustment mechanism 3, cutting execution unit 4, buttoning execution unit 5, and material transfer mechanism 6, ensuring the normal operation of each mechanism.

[0105] The equipment's core structure features an ingenious layout, consisting of three pitch boom units and a lateral slewing boom. The center boom is equipped with an automatic cutting device, while the side booms feature automatic buttoning devices. This layout ensures seamless process integration and significantly improves operational efficiency. The slewing boom is responsible for transporting and lifting the belt reels. Its compact design significantly reduces the equipment's footprint, making it particularly suitable for space-constrained underground work environments. A central vertical cylinder precisely adjusts the height of the cutting and buttoning mechanisms, as well as the position of the lifting platform, ensuring high operational quality standards. It also effectively reduces the difficulty of manual operation and mitigates the impact of human factors on operations.

[0106] like Figure 2 As shown, the angle-adaptive assembly includes spherical movable joints 2-3. The outputs of the front support cylinders 2-1 and rear support cylinders 2-2 are hinged to the inputs of their respective spherical movable joints 2-3. The outputs of the spherical movable joints 2-3 are connected to support plates 2-4. The ends of support plates 2-4 are fitted with anti-slip and wear-resistant pads. This design allows the equipment to move flexibly and autonomously while remaining securely fixed during operation, ensuring safety and stability.

[0107] During operation, the rear support cylinder group 2-2 pushes the equipment under the belt conveyor, and the front support cylinder group 2-1 coordinates and retracts to quickly position the equipment, allowing it to accurately reach the operating position. After the operation is completed, the equipment can quickly exit the work area, greatly shortening equipment deployment time and improving operating efficiency. The equipment adopts a standardized four-step process of "positioning-adjustment-operation-reset". First, the equipment position is determined by adjusting the height system to ensure that the equipment is at the optimal operating height; then the cantilever parameters are adjusted to adapt each cantilever to the operating requirements; then the cutting and fastening mechanisms work together according to the program to achieve rapid cutting and fastening of the belt; finally, each device is reset to prepare for the next operation. Compared with traditional processes, this solution significantly shortens repair time while effectively reducing the safety hazards caused by manual intervention, providing an efficient and reliable solution for coal mine belt maintenance.

[0108] Furthermore, to ensure the stable fixation of the front support cylinder group 2-1 and the rear support cylinder group 2-2, their cylinder barrels are fixed to the base plate 1 via nested cylinder group fixing fixtures 2-5 and fastening bolts 2-6 with pre-tightening function. This fixing method can ensure that the cylinders will not loosen or move during operation, improving the reliability and stability of the equipment.
