Description

Technical Field

[0001] This utility model relates to the field of fire protection pipeline installation technology, and in particular to a fixing device for fire protection pipelines. Background Technology

[0002] In fire protection system installation projects, the stability of fire protection pipelines directly affects the safe operation and service life of the entire fire protection system. Currently, most mainstream fire protection pipeline fixing devices on the market adopt the traditional structure of "base + bolt pressure plate". This type of structure has many limitations in practical applications. For example, the pipeline is fixed by directly applying pressure by tightening bolts. The bolt pressure plate is often fixed with multiple sets of bolts. During installation, the bolt holes must be aligned one by one and the bolts tightened. The operation steps are cumbersome. Especially in high-altitude pipeline installation operations, workers need to use both hands to complete the bolt installation and tightening, which not only increases the difficulty of operation but also poses certain safety risks. At the same time, when the pipeline needs to be inspected or replaced, the bolts must be removed one by one, which prolongs the maintenance time and affects the emergency response efficiency of the fire protection system.

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

[0004] To solve the above-mentioned technical problems, this utility model provides a fixing device for fire protection pipelines.

[0005] The fire-fighting pipeline fixing device provided by this utility model includes a support steel plate, a semi-circular base is fixedly welded on the support steel plate, and a V-shaped pressing steel plate for pressing the pipeline and a pressure adjusting component for adjusting the pressing force of the V-shaped pressing steel plate are provided on the support steel plate.

[0006] The pressure regulating component includes a U-shaped frame, which is fixedly welded to the middle section of the supporting steel plate. A rotating tube with a rotatable connection is installed on the U-shaped frame, and a rocker arm is fixedly welded to the rotating tube. One end of the rocker arm is rotatably connected to a V-shaped pressed steel plate, and the other end of the rocker arm is rotatably connected to a nut through a rotating bracket. A threaded rod with a threaded connection is inserted into the nut, and the bottom of the threaded rod is rotatably connected to the supporting steel plate.

[0007] Preferably, a connecting rod is fixedly welded to one end of the rocker arm away from the nut, and a rotating connecting ring is fitted on both sides of the connecting rod head, and the two connecting rings are fixedly welded to the spine of the V-shaped press-fit steel plate.

[0008] Preferably, the upper end of the threaded rod is fixedly welded with a handle.

[0009] Preferably, the semi-circular base has a plurality of annularly distributed mounting holes on its arc-shaped surface, and each mounting hole is provided with an abutting component.

[0010] Preferably, the abutting component includes a sliding post, which is inserted into the mounting hole and elastically connected to the mounting hole, and the head of the sliding post extends out of the mounting hole and is fitted with a rotatably connected steel ball.

[0011] Preferably, a spring is fixedly installed at the bottom of the sliding column, and the other end of the spring is fixedly connected to the inner bottom wall of the mounting hole.

[0012] Preferably, a fixing plate is fixedly welded to the end of the supporting steel plate away from the semi-circular base.

[0013] Preferably, a rubber pad is fixedly adhered to the inner surface of the V-shaped pressed steel plate.

[0014] Compared with related technologies, the fixing device for fire-fighting pipelines provided by this utility model has the following advantages:

[0015] This invention uses a handle to rotate a threaded rod, which in turn moves a nut up and down along the threaded rod, thereby controlling the movement of one end of a rocker arm. This allows for the adjustment of the pressure on the pipeline by the V-shaped press-fit steel plate. Operators can effectively control the pressure by controlling the number of rotations of the handle, reducing the pressure runaway problem caused by direct bolt pressure. Furthermore, no bolt tightening is required, making operation simple and convenient. Additionally, a rubber pad is fixedly adhered to the inner surface of the V-shaped press-fit steel plate. This rubber pad not only increases friction with the outer wall of the pipeline, improving stability, but also buffers the direct pressure of the V-shaped press-fit steel plate on the pipeline, preventing damage to the galvanized layer of the pipeline's outer wall, effectively protecting the pipeline's integrity and extending its service life.

[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 3 This utility model provides a fixing device for fire-fighting pipelines, which includes a supporting steel plate 1, a semi-circular base 2, a V-shaped pressed steel plate 3, and a pressure regulating component 4.

[0023] In the embodiments of this utility model, please refer to Figures 1 to 3 A semi-circular base 2 is fixedly welded on the supporting steel plate 1, and a V-shaped pressing steel plate 3 for pressing the pipe and a pressure adjusting component 4 for adjusting the pressing force of the V-shaped pressing steel plate 3 are provided on the supporting steel plate 1. A rubber pad 31 is fixedly glued to the inner plate surface of the V-shaped pressing steel plate 3.

[0024] The pressure regulating component 4 includes a U-shaped frame 41, which is fixedly welded to the middle section of the supporting steel plate 1. A rotating pipe 42 is installed on the U-shaped frame 41, and a rocker arm 43 is fixedly welded to the rotating pipe 42. One end of the rocker arm 43 is rotatably connected to the V-shaped pressed steel plate 3. Specifically, a connecting rod 44 is fixedly welded to the end of the rocker arm 43 away from the nut 45, and a rotating connecting sleeve ring 441 is fitted on both sides of the connecting rod 44. The two sleeve rings 441 are fixedly welded to the spine of the V-shaped pressed steel plate 3. The other end of the rocker arm 43 is fitted with a rotating nut 45 through a rotating bracket. A threaded rod 46 is inserted into the nut 45, and the bottom of the threaded rod 46 is rotatably connected to the supporting steel plate 1. A handle 461 is fixedly welded to the upper end of the threaded rod 46. A fixing plate 6 is fixedly welded to the end of the supporting steel plate 1 away from the semi-circular base 2.

[0025] It should be noted that: the fixing plate 6 is fixed to the fire pipeline routing area using screws, and then the fire pipeline is placed on the semi-circular base 2 from the side. Then, the handle 461 is turned to drive the threaded rod 46 to rotate. As a result, the nut 45 rises along the threaded rod 46 and drives the rocker arm 43 on the same side to tilt upwards. Therefore, the rocker arm 43 on the other side presses down on the V-shaped pressing steel plate 3, thereby driving the V-shaped pressing steel plate 3 to press onto the fire pipeline, thus quickly completing the fixing of the fire pipeline.

[0026] When the reverse handle 461 drives the threaded rod 46 to rotate in the opposite direction, the nut 45 descends along the threaded rod 46 and drives the rocker arm 43 on the same side to tilt downwards. As a result, the rocker arm 43 on the other side drives the V-shaped pressing steel plate 3 to lift upwards. Therefore, the V-shaped pressing steel plate 3 is no longer pressed onto the fire pipe, making it easier for staff to remove the fire pipe.

[0027] In this application, rotating the handle 461 drives the threaded rod 46 to rotate, which in turn causes the nut 45 to rise and fall along the threaded rod 46, thereby controlling the rise and fall of one end of the rocker arm 43. This achieves the adjustment of the pipeline pressure by the V-shaped press-fit steel plate 3. By controlling the number of rotations of the handle 461, the operator can effectively control the pressure, reducing the pressure runaway problem caused by direct pressure application with traditional bolts. Furthermore, there is no need to install and tighten bolts, making the operation simple and convenient. At the same time, the inner plate surface of the V-shaped press-fit steel plate 3 is fixedly bonded with a rubber pad 31. The rubber pad 31 not only increases the friction with the outer wall of the pipeline and improves the stability of the fixation, but also buffers the direct pressure of the V-shaped press-fit steel plate 3 on the pipeline, preventing damage to the galvanized layer of the pipeline outer wall, effectively protecting the integrity of the pipeline, and extending the service life of the pipeline.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 3 The semi-circular base 2 has several ring-shaped mounting holes 2a on its arc surface, and each mounting hole 2a is provided with an abutting component 5. The abutting component 5 includes a sliding post 51, which is inserted into the mounting hole 2a and elastically connected to the mounting hole 2a. A spring 53 is fixedly installed at the bottom of the sliding post 51, and the other end of the spring 53 is fixedly connected to the inner bottom wall of the mounting hole 2a. The head of the sliding post 51 extends out of the mounting hole 2a and is fitted with a rotatably connected steel ball 52.

[0029] It should be noted that after the fire-fighting pipeline is installed on the semi-circular base 2, the steel ball 52 at the end of the sliding column 51 is driven by the spring 53 to abut against the fire-fighting pipeline. When the fire-fighting pipeline vibrates while transporting water, the spring 53 in each abutting component 5 can effectively absorb some of the vibration internal stress of the fire-fighting pipeline, thereby effectively reducing the amplitude of the fire-fighting pipeline. The steel ball 52 can convert the radial friction of the fire-fighting pipeline into rolling friction, avoiding damage to the coating of the fire-fighting pipeline and scratches on the surface of the fire-fighting pipeline.

[0030] In addition, to eliminate the potential risk of spring 53 rusting and losing its elasticity due to contact with water, spring 53 is made of stainless steel or titanium alloy to improve corrosion resistance. At the same time, a polytetrafluoroethylene (PTFE) coating is applied to the surface of spring 53 to enhance its rust prevention ability.

[0031] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
