Description

Technical Field

[0001] This utility model relates to the field of coal mine safety protection technology, specifically a safety isolation fence for coal mine roadways. Background Technology

[0002] Safety barriers are facilities used for separation, protection, and warning, and are widely used in various places to ensure the safety of personnel, equipment, and areas.

[0003] Currently, in scenarios such as bends in coal mine roadways or areas where equipment enters or exits, it may be impossible to flexibly and accurately adjust the isolation range and angle, resulting in poor isolation effects and failing to meet actual usage needs. In view of this, we propose a safety isolation fence for coal mine roadways. Utility Model Content

[0004] The main objective of this invention is to provide a safety barrier for coal mine roadways that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model proposes a safety barrier for coal mine roadways, comprising a main barrier with a clearance groove on its surface. The main barrier is rotatably connected to a secondary barrier via a movable adjustment device. The secondary barrier also has a clearance groove and a locking device. The movable adjustment device includes:

[0006] A rotating plate is rotatably connected to the clearance groove, and a gear is rotatably connected to the rotating plate;

[0007] Gear 2, which meshes with Gear 1; the main isolation barrier is threadedly connected to the threaded section of the sliding rod; and the sliding rod is fixedly connected to a locking block on the outer wall of the clearance groove.

[0008] A return spring is provided, and a sliding ring is rotatably connected to the sliding rod. The sliding ring is elastically connected to the main isolation fence through the return spring, and a handle is fixedly connected to the top of the sliding rod.

[0009] Preferably, the first gear is rotatably connected to the clearance groove of the secondary isolation barrier, and the second gear is rotatably connected to the clearance groove of the main isolation barrier.

[0010] Preferably, the locking device includes a fixing rod, and the secondary isolation fence is fixedly connected to the fixing rod. After use, during the rotation and storage of the secondary isolation fence, the fixing rod moves synchronously.

[0011] Preferably, the main isolation fence is fixedly connected to a fixing plate, the surface of the fixing plate is fixedly connected to an extension plate, and four corner blocks are rotatably connected to the extension plate. When the fixing rod approaches the main isolation fence, it presses the lower surface of the four corner blocks.

[0012] Preferably, the extension plate is fitted with a sliding frame, and the sliding frame is fixedly connected to a blocking block, thereby causing the four corner blocks to rotate and press the blocking block to move upward.

[0013] Preferably, the blocking block is positioned above the four corner blocks, and the fixing rod is retracted into the gap between the four corner blocks and the fixing plate. The blocking block and the sliding frame slide onto the extension plate under the action of gravity, and the blocking block continues to prevent the four corner blocks from flipping.

[0014] This utility model provides a safety barrier for coal mine roadways. It has the following beneficial effects:

[0015] (1) The safety barrier for coal mine roadways, through the movable adjustment device, can adjust the angle of the secondary barrier relatively accurately and smoothly through the meshing transmission of gear one and gear two, so as to meet the diverse needs of the barrier angle in different scenarios in coal mine roadways. For example, at roadway bends or equipment entry and exit areas, the isolation range and angle can be flexibly adjusted. The locking block blocks gear two to prevent meshing movement, effectively preventing the secondary barrier from being displaced due to external forces such as vibration and collision in the coal mine roadway, ensuring the stability and reliability of the overall structure of the barrier, and providing a guarantee for safe production in coal mines.

[0016] (2) The safety barrier in the coal mine roadway is equipped with a locking device. The locking and unlocking process of the locking device is automatically completed by the interaction between the fixed rod and the four corner blocks when the secondary barrier rotates. This reduces the labor intensity and operation difficulty of the operators and improves the work efficiency. The blocking block prevents the four corner blocks from flipping and ensures that the fixed rod will not easily come out. Even in complex environments such as vibration in the coal mine roadway, it can maintain good stability and ensure the stability of the barrier structure. Attached Figure Description

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 This utility model proposes a safety isolation fence for coal mine roadways, including a main isolation fence 1. The surface of the main isolation fence 1 is provided with a clearance groove 101. The main isolation fence 1 is rotatably connected to the secondary isolation fence 3 through a movable adjustment device 2. The secondary isolation fence 3 is provided with a clearance groove 101 and a locking device 4 is provided on the secondary isolation fence 3. The movable adjustment device 2 includes a rotating plate 21.

[0030] In this embodiment of the utility model, in order to ensure the stability and reliability of the overall structure of the isolation fence and provide a guarantee for safe production in coal mines, specifically, a rotating plate 21 is rotatably connected in the clearance groove 101, a gear 22 is rotatably connected to the rotating plate 21, and a gear 23 is meshed with the gear 22. The main isolation fence 1 is threadedly connected to the threaded section 26 of the sliding rod 24, and a locking block 25 is fixedly connected to the outer wall of the clearance groove 101 on the sliding rod 24. By rotating the secondary isolation fence 3, the gear 22 meshes with the gear 23, so that the secondary isolation fence 3 can rotate smoothly to adjust the angle. The gear 22 is rotatably connected to the clearance groove 1 of the secondary isolation fence 3. In section 01, gear 23 is rotatably connected to the clearance groove 101 of the main isolation barrier 1. Sliding rod 24 is rotatably connected to sliding ring 28. Sliding ring 28 is elastically connected to the main isolation barrier 1 through return spring 27. A handle 29 is fixedly connected to the top of sliding rod 24. When the handle 29 is stationary, the locking block 25 on sliding rod 24 locks gear 23, preventing meshing. When it is necessary to adjust the angle of the secondary isolation barrier 3, the handle 29 is rotated upward, and sliding rod 24 will move upward in a spiral. The originally compressed return spring 27 releases its elastic potential energy, further driving sliding rod 24 to pop up, so that the locking block 25 releases the limiting relationship of gear 23.

[0031] Furthermore, to ensure the stability of the isolation fence structure, the locking device 4 specifically includes a fixing rod 41. The secondary isolation fence 3 is fixedly connected to the fixing rod 41. After use, during the rotation and storage of the secondary isolation fence 3, the fixing rod 41 moves synchronously. The main isolation fence 1 is fixedly connected to a fixing plate 42. An extension plate 43 is fixedly connected to the surface of the fixing plate 42. Four corner blocks 44 are rotatably connected to the extension plate 43. When the fixing rod 41 approaches the main isolation fence 1, it presses against the lower surface of the four corner blocks 44. A sliding frame is sleeved on the extension plate 43. 45, and the sliding frame 45 is fixedly connected to the blocking block 46, so that the four corner blocks 44 rotate and press the blocking block 46 to move upward. The blocking block 46 is set above the four corner blocks 44, and the fixing rod 41 is stored in the gap between the four corner blocks 44 and the fixing plate 42. The blocking block 46 and the sliding frame 45 slide to the extension plate 43 under the action of gravity. The blocking block 46 continues to prevent the four corner blocks 44 from flipping, thereby locking the fixing rod 41 in the current position, realizing the storage and locking of the secondary isolation fence 3, and preventing it from being accidentally deployed when not in use.

[0032] In this invention, when the handle 29 is stationary, the locking block 25 on the sliding rod 24 engages the gear 23, preventing meshing. The relative positions of the main isolation barrier 1 and the secondary isolation barrier 3 are fixed, ensuring that the isolation barrier will not shift due to external forces or other factors, thus maintaining the stability of the isolation area in the coal mine roadway. When it is necessary to adjust the angle of the secondary isolation barrier 3, the handle 29 is rotated upwards, causing the sliding rod 24 to move upwards threadedly. The previously compressed return spring 27 releases its elastic potential energy, further pushing the sliding rod 24 upwards. This releases the locking block 25 from the gear 23, allowing the secondary isolation barrier 3 to rotate smoothly to adjust its angle. To meet the different spatial needs or isolation requirements of coal mine roadways, after use, during the rotation and storage of the secondary isolation fence 3, the fixing rod 41 moves synchronously. When the fixing rod 41 approaches the main isolation fence 1, it presses the lower surface of the four corner blocks 44, causing the four corner blocks 44 to rotate. This presses the blocking block 46 to move upward, and the fixing rod 41 is stored in the gap between the four corner blocks 44 and the fixing plate 42. Under the action of gravity, the blocking block 46 and the sliding frame 45 slide onto the extension plate 43. The blocking block 46 continues to prevent the four corner blocks 44 from flipping, thereby locking the fixing rod 41 in the current position, realizing the storage and locking of the secondary isolation fence 3, and preventing it from being accidentally deployed when not in use.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
