Description

Technical Field

[0001] This utility model relates to the field of tunnel belt recycling technology, and in particular to a rapid recycling device for a long-distance tunnel horizontal belt. Background Technology

[0002] In the construction of long-distance tunnels, belt conveyor systems have become an indispensable and important component due to their efficient and continuous material transport capabilities. During the construction of long-distance tunnels, the recovery of belts, as a crucial transportation tool, is a key step in the construction process.

[0003] Currently, traditional tunnel conveyor belt recovery mostly relies on manual winding. This method not only consumes a lot of manpower but is also slow and inefficient. Especially when dealing with the task of recovering a large number of conveyor belts in long tunnels, it takes too long, seriously affecting the construction cycle and increasing construction costs. Furthermore, there is a lack of effective correction measures during the winding process, making it impossible to correct the belt deviation in time. Once the belt deviates, it can easily lead to winding chaos and wrinkles, which not only affects the quality and regularity of the recovered belt but may also cause equipment failure due to uneven belt winding, increasing maintenance costs and safety hazards.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0050] Reference Figures 1-6 A rapid recovery device for a horizontal conveyor belt in a long-distance tunnel includes a base frame 1. The base frame 1 can be made of Q355B low-alloy high-strength structural steel with a yield strength ≥355MPa and a tensile strength of 610-750MPa. It has good compressive and bending resistance and is suitable for heavy-load conditions in long-distance tunnel operations. The surface of the base frame 1 is hot-dip galvanized, which can effectively resist corrosion caused by the humid and dusty environment in the tunnel and extend its service life. At the same time, the overall design of the base frame 1 has a static load capacity of more than 5000kg and a dynamic load capacity of more than 8000N, ensuring operational stability and stably supporting the weight of the winding roller 6, the motor 3, and the fully loaded tunnel conveyor belt 7.

[0051] A mounting base 2 is fixedly connected to the side wall of the base frame 1. A motor 3 is fixedly connected to the mounting base 2. A rotating shaft 4 is fixedly connected to the output end of the motor 3. A concave block 5 is fixedly connected to the side wall of the rotating shaft 4. A take-up roller 6 is held in the middle of the concave block 5. A screw 51 is threadedly connected to the top of the concave block 5. A pressing pad 52 is fixedly connected to the bottom of the screw 51. The pressing pad 52 is in contact with the take-up roller 6. A tunnel belt 7 is wound around the outer ring of the take-up roller 6.

[0052] A rapid recovery device for a long-distance tunnel horizontal conveyor belt also includes a correction component 8 and a cutting component 9. The correction component 8 facilitates correction and adjustment of the tunnel conveyor belt 7 during winding. The correction component 8 includes a limiting roller 81, a connecting frame 82, a cavity 83, a spring 84, a slide 85, a fixing rod 86, a limiting wheel 87, a support block 88, a second limiting roller 89, a connecting plate 810, a pin 811, a groove 812, and a hole 813. The first limiting roller 81 is fixedly connected to the base frame 1, providing initial support and guidance for the tunnel conveyor belt 7. The connecting frame 82 is fixed to the side wall of the first limiting roller 81. The cavity 83 is opened inside the connecting frame 82, providing installation and movement space for subsequent components. The spring 84 is fixedly connected to the connecting frame 82. On the inner wall of the cavity 83, the slide 85 is slidably connected to the cavity 83 of the connecting frame 82. The fixing rod 86 is fixed to the slide 85, and the limiting wheel 87 is rotatably connected to the fixing rod 86. The slide 85 and the connecting frame 82 are elastically connected by a spring 84. Springs 84 are provided on both sides of the tunnel belt 7. When the tunnel belt 7 deviates to one side, the spring 84 on one side is compressed, and the elastic force increases, while the spring 84 on the other side is stretched, and the elastic force also increases. The opposing elastic forces generated by the springs 84 on both sides will form a restoring force, causing the tunnel belt 7 to return to the center position. The connecting frame 82, springs 84, slide 85, fixing rod 86 and limiting wheel 87 are all symmetrically arranged, and the limiting wheel 87 is in contact with both sides of the belt. Through this arrangement, no matter which side the tunnel belt 7 deviates to during winding, the correction components 8 on both sides can correct the tunnel belt 7 from both sides in a timely manner, ensuring the stability and straightness of the belt during the winding process.

[0053] A chute 812 is formed on the base frame 1. A support block 88 is slidably connected within the chute 812. A second limiting roller 89 is rotatably connected to the support block 88. A connecting plate 810 is fixedly connected to the side wall of the support block 88. A pin 811 is slidably connected to the connecting plate 810. The insertion position of the pin 811 can be precisely selected according to actual needs, thereby fixing the position of the support block 88 and placing the second limiting roller 89 in a suitable auxiliary correction position, further ensuring the correct winding of the belt. Insertion holes 813 are formed on the base frame 1 and are linearly distributed. The pin 811 is inserted into the insertion holes 813.

[0054] The cutting assembly 9 facilitates the cutting of the wound tunnel belt 7. The cutting assembly 9 includes a U-shaped seat 91, a cylinder 92, a mounting plate 93, a cutter 94, a protective plate 95, a notch 96, and a receiving plate 97. The U-shaped seat 91 is fixedly connected to the base frame 1, the cylinder 92 is fixedly connected to the U-shaped seat 91, the mounting plate 93 is fixedly connected to the output end of the cylinder 92, and the cutter 94 is fixedly connected to the mounting plate 93. The blade of the cutter 94 is made of cold-work die steel, which has high hardness and can effectively cut thicker rubber or polyester fiber tunnel belts 7. The blade body is made of 42CrMo alloy structural steel, which balances tensile strength, toughness, and rigidity to avoid deformation of the blade body during cutting. With the thrust of the cylinder 92, the cutter 94 can generate a large shearing force to meet the cutting requirements of conventional tunnel belts 7.

[0055] The protective plate 95 is fixedly connected to the base frame 1. A notch 96 is formed on the protective plate 95, and the cutter 94 is slidably connected to the notch 96. The protective plate 95 not only guides the running trajectory of the cutter 94, but also prevents the cutter 94 from damaging the base frame 1 or other components during cutting. It also provides a certain degree of safety protection, preventing operators from accidentally coming into contact with the cutter 94. A receiving plate 97 is fixedly installed on the base frame 1, and the receiving plate 97 is set at the same horizontal plane as the cutter 94. The surface of the receiving plate 97 can withstand large local compressive stress, does not deform after long-term use, and its surface is quenched and tempered, resulting in a high wear resistance coefficient, which can reduce frictional loss with the tunnel belt 7.

[0056] It should be noted that before the winding operation, the tunnel conveyor belt 7 was adjusted to a taut state by the workers and kept in a non-contact state with the receiving plate 97. Due to sufficient winding tension, the belt remained taut throughout the winding process, ensuring that it would not come into contact with the receiving plate 97. In addition, the distance between the receiving plate 97 and the protective plate 95 will be dynamically adjusted according to the winding requirements of the tunnel conveyor belt 7 in actual working conditions (the actual distance is not fully shown in the figure due to the scale), in order to avoid wear problems caused by friction between the belt and the receiving plate 97 during the winding process.

[0057] The functional principle of this utility model can be explained through the following operation methods:

[0058] The take-up roller 6 is clamped between the concave blocks 5 and clamped by rotating the screw 51 connected to the top thread. When the screw 51 is rotated, the pressing pad 52 fixedly connected to its bottom will move downward until it fits tightly against the take-up roller 6, thereby firmly fixing the take-up roller 6 between the concave blocks 5.

[0059] Then, the position of the second limiting roller 89 is adjusted according to the thickness of the tunnel belt 7 to be wound. During adjustment, the pin 811 is pulled out to disengage it from the insertion hole 813, and then the second limiting roller 89 is pushed. When the limiting roller is pushed, the support blocks 88 at both ends of it also move horizontally along the slide groove 812. When it moves to the appropriate position, the pin 811 is pushed down to make the pin 811 embed into the corresponding insertion hole 813. The interference fit between the pin 811 and the insertion hole 813 is used to achieve rigid limiting and prevent the tunnel belt 7 from being displaced during the winding process. After the adjustment is completed, the second limiting roller 89 is in a suitable auxiliary correction position so that the tunnel belt 7 will not curl or fold during the winding process, further ensuring the correct winding of the tunnel belt 7. Then, the tunnel belt 7 is passed through the gap between the first limiting roller 81 and the second limiting roller 89, the guide channel of the receiving seat and the protective plate 95 in sequence, and finally the first end of the tunnel belt 7 is fixed to the surface of the winding roller 6.

[0060] Furthermore, during the placement of the tunnel belt 7, the tunnel belt 7 will abut against the limiting wheel 87. The limiting wheel 87 moves under the thrust, causing the slide 85 on its end side to slide into the cavity 83 of the connecting frame 82 under the force. While sliding, the spring 84 is squeezed until the tunnel belt 7 is stably placed, and the resistance is released. The spring 84 then uses its own properties to drive the limiting wheel 87 to reset, so that the limiting wheel 87 always fits against both ends of the tunnel belt 7. This pushes the limiting wheel 87 to reset and press against the edge of the belt. Real-time correction is achieved through double-sided elastic abutment, preventing the belt from shifting laterally during the winding process.

[0061] After the adjustment is completed, start motor 3. Since the output end of motor 3 is fixedly connected to the rotating shaft 4, when motor 3 starts, its output end drives the rotating shaft 4 to rotate. Since the concave block 5 is fixedly connected to the side wall of the rotating shaft 4, the concave block 5 will rotate together with the rotating shaft 4. As the concave block 5 and the winding roller 6 rotate, the tunnel belt 7 wrapped around the outer ring of the winding roller 6 begins to be wound up. Motor 3 continues to run, continuously providing power for the winding process, so that the belt is gradually wrapped tightly on the winding roller 6, completing the belt recycling and winding work.

[0062] After the tunnel belt 7 is wound up, the piston rod of cylinder 92 pushes the mounting plate 93 to move horizontally. The cutter 94, fixed to the mounting plate 93, slides synchronously along the notch 96 of the protective plate 95. The cutter 94 and the notch 96 form a precisely matched shearing pair. When the cutter 94 slides above the receiving plate 97, the belt is clamped between the cutter 94 and the receiving plate 97. The belt is instantly cut by the thrust of cylinder 92, which quickly cuts the tunnel belt 7. After the cutting is completed, the screw 51 is rotated to make the clamping pad 52 disengage from the winding roller 6. The worker then removes it. At this point, the winding work is completed.

[0063] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
