Description

Technical Field

[0001] This utility model relates to the field of fire pipe clamping technology, and in particular to a fire pipe clamping device. Background Technology

[0002] In firefighting operations and related pipeline maintenance scenarios, temporary water shut-off and secure clamping of fire pipes are crucial for ensuring operational safety and improving efficiency. Currently available fire pipe clamping devices generally suffer from complex structural designs and cumbersome operating procedures. For example, devices using multiple sets of bolts for linkage clamping require operators to tighten or loosen each bolt individually in emergency water shut-off scenarios, which not only consumes a lot of time but may also cause delays in handling the situation. Other devices rely on hydraulic or pneumatic drives, which can achieve rapid clamping, but these devices are large and heavy, require ample space in the work area, and need an additional power source, making them difficult to use flexibly in confined spaces or emergency scenarios without power supply.

[0003] Therefore, it is necessary to provide a new fire pipe clamping device to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fire pipe clamping device.

[0005] The fire pipe clamping device provided by this utility model includes a mounting plate, a back plate is fixedly fitted on one side of the mounting plate, and the mounting plate and the back plate form an L-shaped structure.

[0006] An arc-shaped water-cutting plate is installed on the back plate. An arc-shaped pressing block is fixedly fitted at the bottom of the arc-shaped water-cutting plate, and a side collar is fixedly installed at the waist of the arc-shaped water-cutting plate. The side collar is sleeved on a rotating shaft fixedly installed on the back plate, and the side collar is rotatably connected to the rotating shaft.

[0007] An open guide ring is fixedly installed at one end of the back plate, and a traction component for pulling the arc-shaped water-cutting plate to deflect around the rotating axis is mounted on the open guide ring. The traction component includes a curved rod, one end of which is rotatably connected to the arc-shaped water-cutting plate, and a traction rod is fixedly installed at the horizontal end of the curved rod. The traction rod is inserted into the open guide ring and slidably connected to the open guide ring.

[0008] Preferably, a rotating connector is fixedly installed at the curved end of the curved rod, and the rotating connector is sleeved on the traction head fixedly installed on the top of the arc-shaped water-cutting plate and rotatably connected to the traction head.

[0009] Preferably, a toothed plate is fixedly fitted onto the traction rod.

[0010] Preferably, a bracket plate is fixedly installed on the open guide ring, and a rotatably connected gear is installed on the bracket plate. The gear meshes with the gear plate, and a crank handle is installed on the gear.

[0011] Preferably, the gear has multiple annularly distributed insertion holes, the bracket plate has limit holes, and limit bolts are inserted into the limit holes.

[0012] Preferably, an open rubber sleeve is fixedly installed on the mounting plate, and the open rubber sleeve is provided with a concave arc-shaped part. When the arc-shaped pressing block is rotated to a state coaxial with the concave arc-shaped part, the arc-shaped pressing block abuts against the concave arc-shaped part.

[0013] Compared with related technologies, the fire pipe clamping device provided by this utility model has the following beneficial effects:

[0014] This invention utilizes a traction component to drive an arc-shaped water-cutting plate to rotate around a pivot, thereby pressing the fire water pipe inside the open rubber sleeve with an arc-shaped pressing block. When the arc-shaped pressing block rotates to a state coaxial with the concave arc-shaped part, the arc-shaped pressing block abuts against the concave arc-shaped part. Therefore, when the arc-shaped pressing block rotates to a state coaxial with the concave arc-shaped part, the section of fire water pipe is pressed shut, thus completing the water cut-off operation. Compared with traditional multi-bolt structures or hydraulic drive structures, it does not require complex multi-step operations or additional power sources, and can be operated by a single person, significantly shortening the operation time in emergency water cut-off scenarios and improving emergency response efficiency.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 4 The present invention provides a fire pipe clamping device, which includes a mounting plate 1, a back plate 3, an arc-shaped water-cutting plate 4, and a traction component 6.

[0023] In the embodiments of this utility model, please refer to Figures 1 to 4 A back plate 3 is fixedly fitted to one side of the mounting plate 1, and the mounting plate 1 and the back plate 3 are in an L-shaped structure. An arc-shaped water-cutting plate 4 is installed on the back plate 3. Specifically, a side collar 42 is fixedly installed on the waist of the arc-shaped water-cutting plate 4. The side collar 42 is fitted onto the rotating shaft 31 fixedly installed on the back plate 3, and the side collar 42 is rotatably connected to the rotating shaft 31. An arc-shaped pressing block 41 is fixedly fitted to the bottom of the arc-shaped water-cutting plate 4, and a traction head 43 is fixedly installed on the top of the arc-shaped water-cutting plate 4. An open rubber sleeve 2 is fixedly installed on the mounting plate 1, and a section of concave arc-shaped part 21 is provided on the open rubber sleeve 2. When the arc-shaped pressing block 41 is rotated to a state coaxial with the concave arc-shaped part 21, the arc-shaped pressing block 41 abuts against the concave arc-shaped part 21.

[0024] An open guide ring 5 is fixedly installed at one end of the back plate 3, and a traction component 6 for traction of the arc-shaped water-cutting plate 4 to deflect around the rotating shaft 31 is mounted on the open guide ring 5.

[0025] It should be noted that when shutting off the fire water pipe, a section of the fire water pipe is placed inside the open rubber sleeve 2. Then, the traction component 6 drives the arc-shaped water shut-off plate 4 to rotate around the rotating shaft 31 (the traction head 43 deflects towards the open guide ring 5), so that the arc-shaped pressing block 41 can press the fire water pipe inside the open rubber sleeve 2. Since the arc-shaped pressing block 41 abuts against the concave arc-shaped part 21 when it rotates to the coaxial state with the concave arc-shaped part 21, the section of fire water pipe is pressed together, thus completing the water shut-off operation. Compared with the traditional multi-bolt structure or hydraulic drive structure, there is no need for complicated multi-step operation or additional power source. A single person can complete the operation, which significantly shortens the operation time in emergency water shut-off scenarios and improves emergency response efficiency.

[0026] In this embodiment: the open rubber sleeve 2 can play a positioning role for the section of fire water pipe, and since the open rubber sleeve 2 is an elastic structure, it can reduce the pressure between the section of fire water pipe and the mounting plate 1. The recessed arc-shaped part 21 can reduce the displacement of the section of fire water pipe after it is pressed by the arc-shaped pressing block 41.

[0027] Preferably, when the fire water pipe is placed inside the open rubber sleeve 2 in this application, the water flow direction is open guide ring 5 → open rubber sleeve 2. Since the arc-shaped pressing block 41 presses the fire water pipe, the water in the fire water pipe near the closed part flows in the pressing direction of the arc-shaped pressing block 41. Therefore, this part of the fire water pipe has a pushing force on the arc-shaped pressing block 41. The pushing force is the same as the rotation pressing direction of the arc-shaped pressing block 41, thus further improving the pressing effect of the arc-shaped pressing block 41 on the fire water pipe.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 4 The traction component 6 includes a curved rod 61, one end of which is rotatably connected to the arc-shaped water-cutting plate 4. Specifically, a rotating connector 62 is fixedly installed at the curved end of the curved rod 61, and the rotating connector 62 is sleeved on the traction head 43 and rotatably connected to the traction head 43. A traction rod 63 is fixedly installed at the horizontal end of the curved rod 61. The traction rod 63 is inserted into the open guide ring 5 and slidably connected to the open guide ring 5. A toothed plate 64 is fixedly fitted on the traction rod 63, and a bracket plate 51 is fixedly installed on the open guide ring 5. A rotatably connected gear 7 is installed on the bracket plate 51. The gear 7 meshes with the toothed plate 64, and a crank 71 is installed on the gear 7. The gear 7 has multiple annularly distributed insertion holes 7a. A limit hole 51a is opened on the bracket plate 51, and a limit bolt 8 is inserted into the limit hole 51a.

[0029] It should be noted that: by turning the crank handle 71 clockwise (as shown in the attached image) Figure 1Taking this as an example, the gear 7 rotates while driving the traction rod 63 to slide away from the open rubber sleeve 2, so that the arc-shaped water-cutting plate 4 rotates around the rotating shaft 31 and causes the arc-shaped pressing block 41 to press and cut off the fire water pipe. Then, the limiting bolt 8 is inserted into the insertion hole 7a corresponding to the limiting hole 51a to complete the locking. When unlocking, the limiting bolt 8 is removed and the crank 71 is reversed, so the arc-shaped pressing block 41 no longer presses the fire water pipe to allow the water to flow. The overall operation is simple and convenient.

[0030] In this embodiment: when the arc-shaped pressing block 41 rotates to a state coaxial with the concave arc-shaped part 21 and abuts against the concave arc-shaped part 21, the insertion hole 7a and the limiting hole 51a are coaxially arranged.

[0031] It is worth noting that this application uses high-strength, corrosion-resistant tooth plates 64 and gears 7 (specific specifications are selected by technicians according to actual conditions and are not limited here), and they are regularly maintained and serviced by firefighters.

[0032] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
