Description

Technical Field

[0001] The utility model belongs to the technical field of fire protection pipeline installation, in particular to a fire protection pipeline installation hanger. Background Art

[0002] Fire pipes are pipe materials that connect firefighting equipment and devices and transport firefighting water, gas or other media. Firefighting pipes play a vital role in buildings. They are not only responsible for providing firefighting water in case of fire, but also related to the safety of people in the building in non-emergency situations.

[0003] During the installation of fire protection pipes, the hangers are usually installed first, and then the pipes are spliced.

[0004] The common installation method is to lift the pipe to the same height as the mounting hanger after the mounting hanger is installed, and then pass it through the mounting hanger from the front or back so that the fire-fighting pipe can be suspended and supported by the mounting hanger, and then operate the fixings on the mounting hanger to fix the fire-fighting pipe one by one.

[0005] This installation method is rather troublesome, so the inventor has proposed a new installation hanger that can change the traditional installation method of fire protection pipes and make the installation of fire protection pipes faster. Summary of the invention

[0006] The purpose of the utility model is to provide a fire protection pipe installation hanger to solve the problems existing in the prior art, which has solved the cumbersome installation steps of the traditional installation hanger and makes the fire protection pipe installation faster.

[0007] To achieve the above purpose, the utility model adopts the following technical solution: a fire pipe installation hanger, comprising a mounting frame and a hanger arranged at the bottom end of the mounting frame, the lower ends of the inner walls on both sides of the hanger are provided with pipe clamps, and the two pipe clamps are staggered front and back;

[0008] The pipe clamping member comprises a fixed half hoop fixed to the lower end of the inner side wall of the hanger, a movable half hoop movably arranged on the other side of the fixed half hoop, and a wedge block arranged on the side of the movable half hoop away from the fixed half hoop;

[0009] A clamping piece matching the pipe clamping piece is provided in the middle of the inner top wall of the hanger, and the clamping piece includes a clamping rod arranged in the middle of the inner top wall of the hanger, a limit block arranged at the bottom end of the clamping rod, a sleeve sleeved on the surface of the clamping rod and the limit block, and a clamping block rotatably installed at the bottom end of the sleeve, and the clamping block is adapted to the two wedge blocks.

[0010] Through the above technical means, after the hanger is installed, the fire pipeline can directly extend into the clamping pipe fitting from below the hanger. By pushing up the fire pipeline from bottom to top to open the movable half hoop in the clamping pipe fitting, the fire pipeline can extend into the interior of the clamping pipe fitting. Subsequently, pull down the sleeve in the pressing member until the pressing block is inserted between the two wedge blocks. Through the extrusion of the pressing block on the wedge blocks and the screw tightening of the sleeve and the pressing rod, the position of the pressing block can be fixed. Furthermore, the two clamping pipe fittings are merged and gathered respectively, and the installation of the fire pipeline can be completed, with the operation being simpler and faster.

[0011] Optionally, the mounting bracket includes a cross plate and a suspension rod welded to the bottom of the cross plate along the horizontal direction. Mounting holes are provided on the four sub - plates of the cross plate, and there are two suspension rods which are symmetrically distributed at the bottom of the cross plate.

[0012] Adopting the form of a cross plate as the contact surface between the mounting bracket and the ceiling wall reduces the situation of the hanger shaking back and forth, thus making the whole hanger more stable.

[0013] Optionally, the hanger is a "C" - shaped frame and the opening direction is opposite to the direction where the mounting bracket is located.

[0014] After the mounting bracket is installed on the ceiling wall, the opening of the hanger naturally faces downwards, and the fire pipeline can directly extend from below the hanger.

[0015] Optionally, the fixed half hoop and the movable half hoop are rotatably connected through a movable shaft, and inner lining pads are fixedly installed on the inner walls of the fixed half hoop and the movable half hoop.

[0016] The inner lining pads make the installation of the fire pipeline more stable, and at the same time, the inner lining pads can also play a certain buffering role.

[0017] Optionally, notches are provided at the bottom ends of the opposite sides of the fixed half hoop and the movable half hoop, and inverted triangular grooves are provided on the bottom surfaces of the opposite sides of the fixed half hoop and the movable half hoop.

[0018] The design of the notches makes it easy to open the fixed half hoop and the movable half hoop, so that the fire pipeline can be easily inserted into the interior of the fixed half hoop and the movable half hoop. And the design of the inverted triangular grooves on the bottom wall makes it even easier to open the fixed half hoop and the movable half hoop.

[0019] Optionally, the opposite sides of the two wedge blocks are both inclined planes and the two inclined planes gradually approach each other from top to bottom. The distance between the bottom ends of the two inclined planes is smaller than the length of the bottom surface of the pressing block. The cross - section of the pressing block is an isosceles trapezoid, and the length of the bottom surface of the pressing block is smaller than the length of the top surface of the pressing block.

[0020] The wedge block with inclined surface design cooperates with the isosceles trapezoidal pressing block, so that the pressing block can move downward continuously, thereby exerting an increasingly greater squeezing force on the two wedge blocks, thereby making the fixed half hoop and the movable half hoop merge more tightly.

[0021] Optionally, a magnet ring is fixedly mounted on the top end of the sleeve side wall, and a galvanized iron sheet is welded to the inner top wall of the hanger.

[0022] The magnet ring can be adsorbed on the galvanized iron sheet, so that the sleeve and the clamping block can be suspended above the pipe clamp before the fire-fighting pipe is installed, thereby preventing the clamping part from affecting the installation of the fire-fighting pipe.

[0023] Optionally, a rectangular cavity extending into the interior of the sleeve is opened at the center of the bottom of the clamping block, and a circular hole connected to the rectangular cavity is provided on the top wall of the sleeve. The inner diameter of the circular hole is smaller than the side length of the cross-section of the rectangular cavity, and the clamping rod movably passes through the circular hole. The limit block is located in the rectangular cavity and is slidably connected to the rectangular cavity.

[0024] The cooperation between the limit block and the rectangular cavity is adopted to realize the guiding effect on the pressing block, ensuring that the inclined surface of the pressing block is aligned with the wedge block.

[0025] Optionally, the clamping block is rotatably connected to the sleeve via a bearing, an inner thread is provided on the inner wall of the circular hole, and an external thread meshing with the internal thread is provided at the bottom end of the clamping rod.

[0026] Before the round hole contacts the external thread at the bottom end of the clamping rod, the clamping rod can rotate and slide freely in the round hole. As the sleeve moves downward, the internal thread at the round hole can form an engagement relationship with the external thread at the bottom end of the clamping rod. After the sleeve is rotated, the clamping block at the bottom of the sleeve will not slide automatically, thereby ensuring the stable squeezing effect of the clamping block on the wedge block.

[0027] Compared with the prior art, the beneficial effect of the utility model is that after the hanger is installed, the two fire-fighting pipes can be directly extended into the pipe clamping fitting from the bottom of the hanger at the same time, and then the clamping block can be inserted between the two wedge blocks by pulling down the sleeve, so that the clamping block squeezes the wedge blocks, so that the pipe clamping fitting will not separate automatically, thereby completing the installation and fixation of the fire-fighting pipe. Compared with the traditional installation method, not only can the two fire-fighting pipes be fixed at one time, but the operation is also simpler, which effectively improves the installation efficiency of the fire-fighting pipe.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0036] like Figure 1 As shown, the specific scheme of the embodiment is as follows: a fire protection pipe installation hanger includes a mounting frame 1 and a hanger 2 arranged at the bottom end of the mounting frame 1, and the lower ends of the inner walls on both sides of the hanger 2 are provided with pipe clamping parts 3, and the middle part of the inner top wall of the hanger 2 is provided with a clamping part 4 matching the pipe clamping part 3.

[0037] In this embodiment, the mounting frame 1 includes a cross plate 11 and a suspension rod 12 welded to the bottom of the cross plate 11 and along the transverse direction. The four sub-plates of the cross plate 11 are all provided with mounting holes, and two suspension rods 12 are provided and centrally symmetrically distributed at the bottom of the cross plate 11.

[0038] A cross plate 11 is used as the contact surface between the mounting frame 1 and the ceiling wall to reduce the front and rear shaking of the hanger 2, thereby making the entire hanger 2 more stable.

[0039] The hanging bracket 2 is a "C"-shaped bracket and the opening direction is opposite to the direction where the mounting bracket 1 is located. After the mounting bracket 1 is installed on the ceiling wall, the opening of the hanging bracket 2 naturally faces downward, and the fire pipeline can directly extend in from below the hanging bracket 2.

[0040] Please refer to Figure 2 , the clamping pipe fitting 3 includes a fixed half hoop 31 fixed to the lower end of the inner side wall of the hanging bracket 2, a movable half hoop 33 movably arranged on the other side of the fixed half hoop 31, and a wedge block 35 arranged on the side of the movable half hoop 33 away from the fixed half hoop 31.

[0041] Please refer to Figure 1 , it should be noted here that the longitudinal width of the clamping pipe fitting 3 is less than half of the longitudinal width of the hanging bracket 2, and the two clamping pipe fittings 3 are staggered front and back. In this way, it can effectively ensure that when two fire pipelines are installed simultaneously, the movable half hoops 33 in the two clamping hangers 3 will not interfere with each other when they are unfolded simultaneously.

[0042] Among them, the fixed half hoop 31 and the movable half hoop 33 are rotatably connected through a movable shaft 32, and inner liners 34 are fixedly installed on the inner walls of the fixed half hoop 31 and the movable half hoop 33. The inner liner 34 is selected from a sponge pad or a rubber pad with deformation ability. The inner liner 34 makes the installation of the fire pipeline more stable, and at the same time, the inner liner 34 can also play a certain buffering role.

[0043] Secondly, a notch is provided at the bottom end of the opposite sides of the fixed half hoop 31 and the movable half hoop 33. The design of the notch makes it easy to open the fixed half hoop 31 and the movable half hoop 33, so that the fire pipeline can be easily inserted into the inside of the fixed half hoop 31 and the movable half hoop 33.

[0044] Inverted triangular grooves are provided on the bottom surfaces of the opposite sides of the fixed half hoop 31 and the movable half hoop 33. When the fire pipeline is pushed up from the notch, it can make it easier to open the fixed half hoop 31 and the movable half hoop 33.

[0045] Please refer to Figure 2-3 , the pressing member 4 includes a pressing rod 41 arranged in the middle of the inner top wall of the hanging bracket 2, a limiting block 42 arranged at the bottom end of the pressing rod 41, a sleeve 43 sleeved on the surfaces of the pressing rod 41 and the limiting block 42, and a pressing block 44 rotatably installed at the bottom end of the sleeve 43. The pressing block 44 is adapted to the two wedge blocks 35.

[0046] Among them, both opposite sides of the two wedge blocks 35 are inclined surfaces and the two inclined surfaces gradually approach each other from top to bottom. The distance between the bottom ends of the two inclined surfaces is less than the length of the bottom surface of the pressing block 44. The front cross-section of the pressing block 44 is an isosceles trapezoid, and the length of the bottom surface of the pressing block 44 is less than the length of the top surface of the pressing block 44.

[0047] It should be noted that the longitudinal length of the clamping block 44 is equal to the longitudinal width of the hanger 2, so as to ensure that the clamping block 44 can squeeze the two wedge blocks 35 at the same time after moving down between the two wedge blocks 35, so that the two pipe clamps 3 can be closed at the same time.

[0048] The inclined wedge block 35 cooperates with the isosceles trapezoidal pressing block 44 so that the pressing block 44 can move downward continuously, thereby exerting an increasing squeezing force on the two wedge blocks 35, thereby making the fixed half hoop 31 and the movable half hoop 33 merge more tightly.

[0049] In this embodiment, a magnet ring 45 is fixedly mounted on the top of the side wall of the sleeve 43, and a galvanized iron sheet is welded to the inner top wall of the hanger 2. The magnet ring 45 can be adsorbed on the galvanized iron sheet, so that the sleeve 43 and the clamping block 44 can be suspended above the pipe clamp 3 before the fire pipe is installed, thereby preventing the clamping member 4 from affecting the installation of the fire pipe.

[0050] Secondly, a rectangular cavity extending to the interior of the sleeve 43 is opened at the center of the bottom of the clamping block 44, and a circular hole connected to the rectangular cavity is provided on the top wall of the sleeve 43. The inner diameter of the circular hole is smaller than the side length of the cross-section of the rectangular cavity. The clamping rod 41 can move through the circular hole, and the limit block 42 is located in the rectangular cavity and is slidably connected to the rectangular cavity.

[0051] The cooperation between the limiting block 42 and the rectangular cavity is adopted to realize the guiding effect on the pressing block 44 , so as to ensure that the inclined surface of the pressing block 44 is aligned with the wedge block 35 .

[0052] It should be noted here that the clamping block 44 is rotatably connected to the sleeve 43 via a bearing, an internal thread is provided on the inner wall of the circular hole, and an external thread engaged with the internal thread is clamped on the bottom end of the clamping rod 41.

[0053] Before the circular hole contacts the external thread at the bottom end of the clamping rod 41, the clamping rod 41 can rotate and slide freely in the circular hole. As the sleeve 43 moves downward, the internal thread at the circular hole can form a meshing relationship with the external thread at the bottom end of the clamping rod 41. After the sleeve 43 is rotated, the clamping block 44 at the bottom of the sleeve 43 will not slide automatically, thereby ensuring the stable squeezing effect of the clamping block 44 on the wedge block 35.

[0054] like Figure 4-5As shown, after the hanger 2 is installed, the fire-fighting pipe extends directly into the pipe clamping fitting 3 from the bottom of the hanger 2. The worker applies a bottom-up thrust to the fire-fighting pipe, and the fire-fighting pipe pushes open the movable half hoop 33 until the fire-fighting pipe extends into the pipe clamping fitting 3. Then the movable half hoop 33 automatically falls back and merges with the fixed half hoop 31, thereby sleeved the fire-fighting pipe inside. Subsequently, the sleeve 43 in the clamping piece 4 is pulled down until the clamping block 44 is inserted between the two wedge blocks 35. The position of the clamping block 44 can be fixed by squeezing the wedge block 35 by the clamping block 44 and tightening the sleeve 43 and the clamping rod 41 through the threads. Then, the two pipe clamping fittings 3 are merged and gathered together to complete the installation of the fire-fighting pipe.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
