Description

Technical Field

[0001] This utility model belongs to the field of fire protection pipeline installation technology, specifically relating to a riser mounting bracket for fire water supply pipelines. Background Technology

[0002] In the field of fire protection pipeline installation, when the riser passes through the floor slab, a sleeve needs to be pre-embedded, and the fire protection riser and the outer sleeve are required to be installed coaxially.

[0003] Fire risers are fixed to the wall using fasteners and clamps. Before using fasteners and clamps to fix the fire riser to the wall, the position of the fire riser needs to be adjusted and positioned so that the fire riser and the outer sleeve axis coincide.

[0004] Currently, the installation of fire risers requires personnel to position them. Due to human error, the fire risers may deviate laterally, resulting in a large axial deviation between the fire riser and the outer sleeve. After installation, repeated measurements and inspections are required, and the position of the fire riser needs to be adjusted based on the measurement and inspection results. The installation process is cumbersome and inconvenient, leading to low efficiency and a heavy workload for the staff. Utility Model Content

[0005] This utility model provides a riser mounting bracket for fire water supply pipelines, which can more conveniently install the fire riser and the sleeve center axis to coincide.

[0006] This utility model provides the following technical solution: a riser mounting bracket for fire water supply pipelines, comprising:

[0007] Two sleeve positioning narrow plates that can move synchronously towards or away from each other via an adjustment mechanism are used to clamp the outer wall of the sleeve;

[0008] Two inner limiting rods are detachably connected to the inner side of the two sleeve positioning narrow plates to increase the connection strength with the sleeve.

[0009] Two fire riser positioning wide plates that can move synchronously towards and away from each other through an adjustment mechanism are located above two sleeve positioning narrow plates to concentrically position the fire riser. The bottom end of the side support frame is flush with the bottom end of the sleeve positioning narrow plate.

[0010] Two side support frames are respectively set on opposite sides of the two sleeve positioning narrow plates, so as to drive the center of the distance between the two sleeve positioning narrow plates to move synchronously with the center of the distance between the two fire riser positioning wide plates.

[0011] The top of each of the two sleeve positioning narrow plates is fixedly connected to an upper convex connecting plate. The top of the upper convex connecting plate is provided with a "U" shaped groove. The inner limiting rod is detachably connected to the inner limiting rod through the upper convex connecting plate.

[0012] The inner walls of the two sleeve positioning narrow plates are each fixedly connected with a sleeve holding block to position the center of the sleeve.

[0013] The inner walls of both fire riser positioning plates are fixedly connected with fire riser holding blocks to position the center of the fire riser.

[0014] Each of the two side support frames has a bottom support block fixedly connected to its bottom end, and the bottom end of the side support frame is flush with the bottom end of the sleeve positioning narrow plate.

[0015] Two limiting rods are fixedly connected between the two side support frames, and the two limiting rods pass through the two sleeve positioning narrow plates and the two fire riser positioning wide plates respectively.

[0016] The adjusting mechanism includes an adjusting screw, two sets of oppositely oriented external threads, and two screw thread sleeves. The adjusting screw located on the narrow sleeve positioning plate is rotatably connected to the narrow sleeve positioning plate, and the adjusting screw located on the wide fire riser positioning plate is rotatably connected to the wide fire riser positioning plate. The external threads are provided on the outer wall of the adjusting screw. The two screw thread sleeves located on the narrow sleeve positioning plate are respectively fixedly connected to the two narrow sleeve positioning plates, and the two screw thread sleeves located on the wide fire riser positioning plate are respectively fixedly connected to the two wide fire riser positioning plates.

[0017] The beneficial effects of this utility model are:

[0018] 1. By clamping and positioning the sleeve and fire riser with two narrow sleeve positioning plates and two wide fire riser positioning plates respectively, and cooperating with the side support frame to position the center of the distance between the two narrow sleeve positioning plates and the two wide fire riser positioning plates, the fire riser can be centered with the fixed sleeve, so that the fire riser and the sleeve can keep their central axis coincident. This makes the installation of the fire riser more accurate and convenient for workers, improves installation efficiency and reduces workload.

[0019] 2. The narrow width design of the sleeve positioning plate and its position close to the ground allow the effective clamping height of the sleeve positioning plate to be close to the ground, which can effectively clamp and position sleeves that protrude from the ground for a short distance. In addition, when combined with the inner limit rod, it can improve the positioning effect of sleeves that protrude from the ground for a short distance, thereby improving the applicability and stability of the device.

[0020] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0026] Please see Figures 1-4 This utility model provides the following technical solution: a riser mounting bracket for fire water supply pipelines, comprising:

[0027] Two sleeve positioning narrow plates 1, which can move synchronously towards or away from each other through the adjustment mechanism 5, are used to clamp the outer wall of the sleeve.

[0028] Two inner limiting rods 2 are detachably connected to the inside of the two sleeve positioning narrow plates 1 to increase the connection strength with the sleeve.

[0029] Two fire riser positioning wide plates 3, which can move synchronously towards and away from each other through the adjustment mechanism 5, are located above two sleeve positioning narrow plates 1 to concentrically position the fire riser.

[0030] Two side support frames 4 are respectively set on opposite sides of the two sleeve positioning narrow plates 1, so as to drive the center of the distance between the two sleeve positioning narrow plates 1 and the center of the distance between the two fire riser positioning wide plates 3 to move synchronously. The bottom end of the side support frame 4 is flush with the bottom end of the sleeve positioning narrow plate 1.

[0031] In this implementation scheme: the adjusting screw 51 extends outward through the side support frame 4 and connects to the rotating rod. By rotating the rotating rod, the adjusting screw 51 is rotated to adjust the two sleeve positioning narrow plates 1 and the two fire riser positioning wide plates 3 to move in opposite directions, moving them to a position close to the side support frame 4. Then, the fire riser is inserted into the sleeve, and the moving device is positioned close to the sleeve. The two sleeve positioning narrow plates 1 are located on both sides of the sleeve, and the two fire riser positioning wide plates 3 are located on both sides of the fire riser. Then, the rotating rod corresponding to the position of the sleeve positioning narrow plates 1 is rotated in the opposite direction to drive the two sleeve positioning narrow plates 1 to move towards each other and clamp them on the outer wall of the sleeve. Then, the positioning bolts on the rotating rod are tightened to squeeze against the side support frame 4, positioning the rotating rod, and then positioning the adjusting screw 51. The vertical rod of the inner limiting rod 2 is inserted between the fire riser and the sleeve, and the horizontal rod of the inner limiting rod 2 is inserted into the "U"-shaped groove on the upper convex connecting plate 11, and so on. Tighten the horizontal bar of the inner limiting rod 2 with a nut until the vertical bar of the inner limiting rod 2 is attached to the inner wall of the sleeve. At this time, the center of the distance between the two sleeve positioning narrow plates 1 coincides with the center of the sleeve. Then, rotate the rotating rod corresponding to the position of the fire riser positioning wide plate 3 in the opposite direction to drive the two fire riser positioning wide plates 3 to move towards each other and clamp them on the outer wall of the fire riser. Similarly, position the rotating rod. At this time, the fire riser is located in the center of the sleeve, and the axis of the fire riser coincides with the axis of the sleeve. After the workers use clamps to fix the fire riser, release the limit on the knob and drive the knob to rotate, so that the two sleeve positioning narrow plates 1 and the other fire riser positioning wide plate 3 move in opposite directions, and remove the device from the fire riser and sleeve side. When placing the device, the inclined side of the side support frame 4 faces away from the wall, the bottom support block 41 is in contact with the ground, and the sleeve positioning narrow plate 1 is above the ground.

[0032] Both sleeve positioning narrow plates 1 are fixedly connected to the top of an upper convex connecting plate 11. The top of the upper convex connecting plate 11 is provided with a "U" shaped groove. The inner limiting rod 2 is detachably connected to the inner limiting rod 2 through the upper convex connecting plate 11. By setting the upper convex connecting plate 11, the connection between the sleeve positioning narrow plate 1 and the inner limiting rod 2 can be facilitated. The upper convex connecting plate 11 is located at the top of the sleeve positioning narrow plate 1, which can avoid occupying the space below the sleeve positioning narrow plate 1, so that the sleeve positioning narrow plate 1 can be close to the ground. The "U" shaped groove of the upper convex connecting plate 11 corresponds to the diameter of the crossbar of the inner limiting rod 2.

[0033] Both sleeve positioning narrow plates 1 are fixedly connected to sleeve holding blocks 12 on their inner walls to position the center of the sleeve. The sleeve holding blocks 12 can clamp the sleeve. When the sleeve holding blocks 12 on both sides are clamped on the outer wall of the sleeve, the center line connecting the two sleeve holding blocks 12 passes through the axis of the sleeve and can limit the translation of the device.

[0034] Both fire riser positioning wide plates 3 have fire riser clamping blocks 31 fixedly connected to their inner walls to position the center of the fire riser. By setting the fire riser clamping blocks 31, the fire riser can be clamped and positioned. When the fire riser clamping blocks 31 on both sides are clamped on the outer wall of the fire riser, the center line connecting the two fire riser clamping blocks 31 passes through the axis of the sleeve. The center connection of the two fire riser clamping blocks 31 is located above the center line connecting the two sleeve clamping blocks 12, so that the center of the fire riser coincides with the center of the sleeve. The wider dimensions of the fire riser positioning wide plate 3 and the fire riser clamping blocks 31 can clamp the fire riser over a large range, thereby preventing the fire riser from deflecting.

[0035] Both side support frames 4 are fixedly connected to bottom support blocks 41 at their bottom ends. The bottom ends of the side support frames 4 are flush with the bottom ends of the sleeve positioning narrow plate 1. By setting the bottom support blocks 41, the side support frames 4 can be supported, so that the sleeve positioning narrow plate 1 is suspended in the air and will not come into contact with the ground and rub against it.

[0036] Two limiting rods 42 are fixedly connected between the two side support frames 4. The two limiting rods 42 pass through the two sleeve positioning narrow plates 1 and the two fire riser positioning wide plates 3 respectively. By setting the limiting rods 42, the sleeve positioning narrow plates 1 and the fire riser positioning wide plates 3 can be limited, thereby preventing the sleeve positioning narrow plates 1 and the fire riser positioning wide plates 3 from rotating with the adjusting screw 51 when the adjusting screw 51 is rotated, thereby realizing the lateral movement of the sleeve positioning narrow plates 1 and the fire riser positioning wide plates 3.

[0037] The adjusting mechanism 5 includes an adjusting screw 51, two sets of external threads 52 in opposite directions, and two screw thread sleeves 53. The adjusting screw 51 located on the narrow sleeve positioning plate 1 is rotatably connected to the narrow sleeve positioning plate 1, and the adjusting screw 51 located on the wide fire riser positioning plate 3 is rotatably connected to the wide fire riser positioning plate 3. The external threads 52 are provided on the outer wall of the adjusting screw 51. The two screw thread sleeves 53 located on the narrow sleeve positioning plate 1 are respectively fixedly connected to the two narrow sleeve positioning plates 1. The screw thread sleeves 53 located on the wide fire riser positioning plate 3 are rotatably connected to the two narrow sleeve positioning plates 1. Two threaded sleeves 53 are fixedly connected to two fire riser positioning wide plates 3 respectively. The threaded sleeves 53 are installed on the corresponding sleeve positioning narrow plates 1 and fire riser positioning wide plates 3. The external thread 52 on the adjusting screw 51 is threadedly connected to the threaded sleeve 53. When the adjusting screw 51 rotates, under the action of the external thread 52 and the internal thread of the threaded sleeve 53, the threaded sleeve 53 moves towards or away from each other, thereby driving the sleeve positioning narrow plates 1 and fire riser positioning wide plates 3 to move towards or away from each other.

[0038] The working principle and usage process of this utility model are as follows: Adjust the two narrow sleeve positioning plates 1 and the two wide fire riser positioning plates 3 to move in opposite directions, moving them to a position close to the side support frame 4. Then, insert the fire riser into the sleeve and move the device close to the sleeve. The two narrow sleeve positioning plates 1 are located on both sides of the sleeve, and the two wide fire riser positioning plates 3 are located on both sides of the fire riser. Then, rotate the rotating rod corresponding to the position of the narrow sleeve positioning plates 1 in the opposite direction to drive the two narrow sleeve positioning plates 1 to move towards each other and clamp them on the outer wall of the sleeve. Then, tighten the positioning bolt on the rotating rod to squeeze it against the side support frame 4, positioning the rotating rod, and then positioning the adjusting screw 51. Finally, insert the vertical rod of the inner limit insert 2 between the fire riser and the sleeve. The horizontal bar of rod 2 is inserted into the "U"-shaped groove on the upper convex connecting plate 11, and the horizontal bar of the inner limiting rod 2 is tightened with a nut until the vertical bar of the inner limiting rod 2 is attached to the inner wall of the sleeve. Then, the rotating rod corresponding to the position of the fire riser positioning wide plate 3 is rotated in the opposite direction to drive the two fire riser positioning wide plates 3 to move towards each other and clamp them on the outer wall of the fire riser. The rotating rod is also positioned. At this time, the fire riser is located in the center of the sleeve, and the axis of the fire riser coincides with the axis of the sleeve. After the workers use clamps to fix the fire riser, the limit of the knob is released, and the knob is driven to rotate, so that the two sleeve positioning narrow plates 1 and the other fire riser positioning wide plate 3 move in opposite directions, and the device is removed from the fire riser and sleeve side.
