Description

Technical Field

[0001] This utility model belongs to the field of mining engineering technology, specifically a head cover for a roadheader. Background Technology

[0002] As the core equipment for tunneling in coal mines, the head of the roadheader is subjected to strong impacts, vibrations, and flying coal and rock fragments during operation. Therefore, it is usually equipped with a special protective cover to protect the head structure, hydraulic lines, and key components from damage, while reducing dust diffusion and improving operational safety.

[0003] Currently, most roadheader shrouds adopt an integral welded or fixed assembly structure, maintaining a fixed external dimension even when not in operation (such as during equipment relocation, maintenance, or storage), thus occupying a large amount of space. This not only affects the roadheader's passage and shunting efficiency in narrow tunnels but also increases the difficulty of underground equipment layout. Especially in tunneling faces with limited cross-sections, excessively large shrouds are prone to interfering with tunnel supports, pipelines, or other equipment. Utility Model Content

[0004] This utility model provides a protective cover for the head of a roadheader to address the deficiencies in the prior art.

[0005] This utility model is achieved through the following technical solution: The tunnel boring machine's gun head cover includes a shielding cloth, an arched bend, and longitudinal beams on both sides of the bend. The shielding cloth is fixedly connected to and supported by the bend. Side plates are vertically fixed to the longitudinal beams. The top surface of the side plates has a downward-facing mounting groove. Multiple pins are arranged horizontally in the mounting groove, arranged from bottom to top. The lowest side bend is fixedly connected to the side plate. The corresponding ends of the remaining bends are inserted into the mounting grooves and vertically connected to the corresponding pins. The shielding cloth folds and unfolds as the bend retracts and expands.

[0006] When in use, the longitudinal beams are placed on both sides of the front end of the gun head, and then the curved tubes are unfolded to cover the gun head. When it is time to store, the curved tubes are simply rotated in the opposite direction to make the tubes fit together, thereby reducing the space occupied and making it easy to move the equipment. Thus, while covering the gun head, the space occupied by the equipment is reduced and it is easy to move.

[0007] Preferably, the two sides of the covering fabric are bent 180 degrees and sewn together to form through holes. The curved tubes at both ends are inserted into the corresponding through holes. Several rows of limiting holes are also fixedly provided on the bottom surface of the covering fabric. The limiting holes are formed by nylon bags, and the curved tubes in the middle pass through the corresponding limiting holes. The through holes and limiting holes ensure that the curved tubes can drive the covering fabric to unfold and fold when rotating.

[0008] Preferably, the pin is vertically connected to an outer tube, which has an internal thread. A lead screw is threaded onto the outer tube, and the lead screw is rotatably connected to the corresponding end of the bent pipe. The threaded connection between the lead screw and the outer tube allows for the connection and disconnection of the bent pipe from the pin, thus enabling the disassembly and replacement of the bent pipe at the connection between the lead screw and the outer tube when it is damaged.

[0009] Preferably, a limiting ring is fixedly installed inside the pipe end, and the lead screw passes through the limiting ring and is vertically connected to a baffle plate with an outer diameter matching the inner diameter of the bend. The cooperation between the baffle plate and the limiting ring ensures that the lead screw will not detach from the bend while rotating inside it.

[0010] Preferably, the bottom surface of the masking fabric is fixedly connected to a first adhesive portion of Velcro, and a limiting hole is fixedly disposed on a second adhesive portion of the Velcro, with the first adhesive portion and the second adhesive portion being bonded together. The Velcro not only facilitates the replacement of the limiting hole, but also increases the thickness at the limiting hole, preventing severe wear of the masking fabric in that area.

[0011] The beneficial effects of this utility model are as follows: the use of this application can achieve the shielding of the cannon head, and when it is necessary to store it, it is only necessary to rotate the bend in the opposite direction so that the bends fit together, thereby reducing the space occupied and making it convenient to move the device. Thus, while satisfying the shielding of the cannon head, it can reduce the space occupied by the device and make it easy to move. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] The head cover of the roadheader, such as Figures 1-4 As shown, it includes a shielding cloth 3, an arched bend 2, and longitudinal beams 1 arranged on both sides of the bend 2. The shielding cloth 3 is fixedly connected to and supported by the bend 2. The shielding cloth 3 covers the bend 2 and bends with the bend 2. The longitudinal beams 1 are vertically fixed with side plates 4. The top surface of the side plates 4 is provided with a mounting groove facing downwards. The mounting groove is provided with a horizontal pin. Multiple pins are arranged from bottom to top. The lowest side bend 2 is fixedly connected to the side plate 4. The corresponding ends of the other bends 2 are inserted into the mounting grooves and vertically connected to the corresponding pins. The shielding cloth 3 folds and unfolds with the bend 2.

[0017] When in use, the longitudinal beam 1 is placed on both sides of the front end of the gun head, and then the curved pipe 2 is unfolded to cover the gun head. When it is necessary to store it, the curved pipe 2 is simply rotated in the opposite direction so that the curved pipes 2 fit together, thereby reducing the space occupied and making it easy to move the equipment. Thus, while satisfying the requirement of covering the gun head, the space occupied by the equipment is reduced and it is easy to move.

[0018] The two sides of the covering fabric 3 are bent 180 degrees and sewn together to form through holes. The curved tubes 2 at both ends are inserted into the corresponding through holes. Several rows of limiting holes 5 are also fixedly provided on the bottom surface of the covering fabric 3. The limiting holes 5 are formed by nylon bags, and the curved tubes 2 in the middle pass through the corresponding limiting holes 5. The through holes and limiting holes 5 can ensure that the curved tubes 2 can drive the covering fabric 3 to unfold and fold when rotating.

[0019] An outer tube 6 is vertically connected to a pin shaft. The outer tube 6 has an internal thread, and a lead screw 7 is threadedly connected to the outer tube 6. The lead screw 7 is rotatably connected to the corresponding end of the bent tube 2. The threaded connection between the lead screw 7 and the outer tube 6 enables the connection and disconnection of the bent tube 2 from the pin shaft. Therefore, if the bent tube 2 is damaged, it can be disassembled and replaced through the connection between the lead screw 7 and the outer tube 6.

[0020] A limiting ring 8 is fixedly installed inside the end of the pipe. The lead screw 7 passes through the limiting ring 8 and is vertically connected to a baffle plate 9 with an outer diameter that matches the inner diameter of the bend 2. The cooperation between the baffle plate 9 and the limiting ring 8 ensures that the lead screw 7 will not detach from the bend 2 while rotating inside the bend 2.

[0021] The bottom surface of the covering fabric 3 is fixedly connected to the first adhesive part 10 of the Velcro, and the limiting hole 5 is fixedly set on the second adhesive part 11 of the Velcro. The first adhesive part 10 and the second adhesive part 11 are bonded together. The Velcro not only makes it easy to replace the limiting hole 5, but also increases the thickness at the limiting hole 5, preventing severe wear of the covering fabric 3 at that point.

[0022] The use of this application can achieve shielding of the cannon head. At the same time, when it is necessary to store it, simply rotate the bend 2 in the opposite direction so that each bend 2 can fit together, thereby reducing the space occupied and making it easy to move the device. Thus, while satisfying the shielding of the cannon head, it can reduce the space occupied by the device and make it easy to move.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
