Description

TECHNICAL FIELD

[0001] The utility model belongs to PVC-C plastic fire-fighting spray pipe technical field, especially relate to a fire-fighting spray pipe lock clamp device. BACKGROUND

[0002] Fire-fighting facilities are important facilities in building structures, and the fire-fighting facilities are used to protect building structures such as buildings, and in the event of a fire, the fire-fighting facilities can quickly control the fire.

[0003] The fire-fighting pipeline and the spray pipeline, the nozzle and other structures installed on the fire-fighting pipeline in the fire-fighting facilities are important components of the fire-fighting facilities, and specifically, when a fire occurs, the fire-fighting pipeline sprays high-pressure water from the spray pipeline and the nozzle at a certain pressure, thereby achieving fire extinguishing.

[0004] At present, more and more spray pipelines use PVC-C and other high molecular materials, and the specific reasons are as follows: PVC-C and other high molecular material pipelines have the advantages of low cost, easy installation and maintenance, long service life, and are not easy to corrode. The installation adopts a suspended ceiling installation method, that is, the spray pipeline is vertically arranged at the ceiling position to realize downward spraying for fire extinguishing.

[0005] However, in actual work, it is found that the plastic spray pipeline made of PVC-C and other high molecular materials shakes due to the extension length of the plastic spray pipeline in the instant of spraying, especially when the length extending from the ceiling is large, the shaking is more intense in the instant of spraying. The specific reason is that the plastic spray pipeline made of PVC-C and other high molecular materials has poor deformation resistance, and easily shakes under the action of high-pressure water in the case of unstable water pressure. The shaking and shaking result in unstable spraying. In the case of unstable high-pressure water spraying, the direction of the sprayed water is uncontrollable.

[0006] Since the ceiling needs to be installed with a suspended ceiling frame, a suspended ceiling plate and other structures in the future, the plastic spray pipeline needs to penetrate the suspended ceiling plate and other structures, and similarly, the shaking spray pipeline in the spraying process reduces the stability of the suspended ceiling plate and other structures, and even causes the suspended ceiling plate to fall off due to the shaking of the spray pipeline.

[0045] Embodiment 1

[0046] As Figures 1-5 ​​As shown in the drawings, a fire sprinkler pipe locking clamp device comprises a ring-shaped mounting frame 1. A plurality of suspension mounting members 11 are mounted on the top of the mounting frame 1. Specifically, the suspension mounting member 11 comprises a screw pipe base 111 fixedly connected to the top of the mounting frame 1, and a screw rod 112 threadedly connected to the screw pipe base 111. According to the prior art, the entire device is mounted on the ceiling or the framework of the suspended ceiling through the suspension mounting member 11 by screw fastening. The sprinkler pipe penetrates through the center of the ring-shaped mounting frame 1.

[0047] A plurality of upper locking clamp structures 2 for locking the sprinkler pipe are mounted on the inner side wall of the mounting frame 1. The upper locking clamp structure 2 is used to lock the upper end (close to the ceiling) of the sprinkler pipe made of plastic material.

[0048] Meanwhile, the mounting frame 1 is provided with a lower supporting clamp mechanism cooperating with the upper locking clamp structure 2. The lower supporting clamp mechanism comprises a plurality of lower supporting clamp assemblies 3 supporting the sprinkler pipe at different heights. The lower supporting clamp assembly 3 comprises a lower supporting clamp frame 35 with an adjustable angle, and a supporting clamp limiting opening is formed in the lower supporting clamp frame 35. The height of the lower supporting clamp frame 35 is adjustable.

[0049] Through the height adjustment and angle adjustment of the lower supporting clamp frame 35, different lower supporting clamp assemblies 3 are supported at different heights and in different directions of the outer side wall of the sprinkler pipe through the lower supporting clamp frame 35, and are sequentially supported from top to bottom along the height of the sprinkler pipe. In combination with the upper locking clamp structure 2, the pipe is supported. Through the two ways, the technical defect that the pipe shakes and swings due to unstable water pressure in the pipe during the sprinkling process is avoided.

[0050] Embodiment 2

[0051] As shown in the drawings, Figures 1-5 Based on the structure of embodiment 1, the specific structure of the upper locking clamp structure 2 is as follows:

[0052] The upper locking clamp structure 2 comprises an arc-shaped locking clamp plate 21 (preferably made of rubber to protect the pipe after clamping). The concave surface of the arc-shaped locking clamp plate 21 faces the pipe, and the arc-shaped locking clamp plate 21 is fixedly connected to the mounting frame 1 through a horizontal spacing adjustment structure.

[0053] Specifically, the horizontal spacing adjustment structure comprises adjustment screws 22 arranged in an upper and lower interval. An adjustment plate 23 is slidably connected between the adjustment screws 22. A pair of nuts 221 are threadedly connected to the adjustment screws 22 and positioned on both sides of the adjustment plate 23. A connecting column 24 is fixedly connected to the adjustment plate 23, and the connecting column 24 is fixedly connected to the mounting frame 1.

[0054] In the working process, the arc-shaped locking clamping plates 21 arranged in a ring are moved towards the spray pipeline and clamped on the spray pipeline. The upper end of the pipeline is locked by the multiple arc-shaped locking clamping plates 21 arranged in a ring.

[0055] After the arc-shaped locking clamping plates 21 are locked, the nuts 221 are repositioned.

[0056] This mode can clamp and position pipelines with different diameters. For example, a pipeline with a large diameter is clamped and positioned around the pipeline by multiple arc-shaped locking clamping plates 21 with arc-shaped structures.

[0057] In the working process, in order to facilitate the replacement of the arc-shaped locking clamping plates 21, the outer wall of the arc-shaped locking clamping plates 21 is fixedly connected with a sleeve seat 211 (a sleeve hole matched with the adjusting screw rod 22 is formed in the sleeve seat 211) sleeving the adjusting screw rod 22. The sleeve seat 211 is threadedly connected with a locking bolt 2111 locking the adjusting screw rod. After the adjusting screw rod 22 is inserted into the sleeve hole, the adjusting screw rod 22 is installed by being pressed by the locking bolt.

[0058] Embodiment 3

[0059] As shown in Figures 1-5 Based on the structure of Embodiment 2, the spray pipeline has a certain extension length from the ceiling. In order to fully clamp the spray pipeline from top to bottom, the lower clamping assembly 3 further comprises a hinged structure.

[0060] Specifically, the hinged structure comprises a hinged seat 33, and the mounting frame 1 is installed and connected with a fixed seat 32 hinged to the hinged seat 33. Specifically, the two ends of the hinged seat 33 are fixedly connected with hinged screw rods 331 hinged to the fixed seat 32, and the hinged screw rods 331 are threadedly connected with positioning nuts 3311. The lower clamping frame 35 is installed on the hinged seat 33.

[0061] In the working process, the positioning nuts 3311 are loosened. At this time, the hinged seat 33 is flipped (the shape of the hinged seat 33 is U-shaped), and the clamping limiting port on the lower clamping frame 35 is clamped on the pipeline after being flipped. Due to the circumferentially distributed lower clamping frames 35, the pipeline is clamped in different directions and at different heights by flipping at different angles and adjusting the height. In this way, the pipeline is clamped at different heights and in different directions, thereby preventing the pipeline from shaking.

[0062] In order to match the different angles of the lower support bracket 35, the lower support bracket 35 is installed on the hinge seat 33 through the height adjusting structure. The fixed seat 32 is installed on the mounting rack 1 through the spacing adjusting structure. The spacing adjusting structure comprises an L-shaped screw rod 31 fixedly connected to the bottom of the mounting rack 1, and the L-shaped screw rod 31 is slidably connected to the fixed seat 32. Meanwhile, a pair of spacing adjusting nuts are threadedly connected to the L-shaped screw rod 31 and positioned on both sides of the fixed seat 32.

[0063] During operation, the operator loosens the spacing adjusting nuts, slides the fixed seat 32, changes the spacing between the lower support bracket 35 and the spray pipeline, and then flips the lower support bracket 35 to adjust the angle, so that the lower support bracket 35 can be clamped on the side wall of the pipeline in the best position.

[0064] Similarly, in order to realize the height adjustment, the height adjusting structure comprises a height adjusting screw rod 341 slidably connected to the hinge seat 33, and a pair of nuts 3411 threadedly connected to the height adjusting screw rod 341 and positioned on both sides of the hinge seat 33. The height adjusting mode is that during the sliding adjustment of the lower support bracket 35 by loosening the nuts 3411, the height adjusting screw rod 341 slides relative to the hinge seat 33 of the U-shaped structure.

[0065] The structure of the lower support bracket 35 is as follows:

[0066] The lower support bracket 35 comprises a lower support bracket portion, and a support clamping limiting opening is formed in the lower support bracket portion. The lower support bracket 35 is integrally formed with a rectangular connecting portion 34, and the height adjusting screw rod 341 is fixedly connected to the rectangular connecting portion 34.

[0067] During operation, the angle adjustment, height adjustment and horizontal spacing adjustment realize the relative position adjustment of the lower support bracket 35 to the pipeline, so that the lower support bracket 35 at different positions can be clamped on the pipeline wall of the spray pipeline in a more stable manner after position adjustment, and the circumferentially distributed lower support brackets 35 are clamped in different heights and directions, effectively solving the technical defects that the pipeline is easily shaken and unstable during the spraying process of the spray pipeline due to unstable water pressure.

[0068] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by those skilled in the art within the scope of the present application should also be within the scope of protection of the present application.
