Description

Technical Field

[0001] This utility model relates to the field of positioning mechanism technology, and in particular to an industrial fixed fire monitor spray angle positioning mechanism. Background Technology

[0002] The industrial fixed fire monitor spray angle positioning mechanism is a key device specifically designed for industrial applications, providing precise spray angle positioning and locking for fixed fire monitors. It mainly consists of a support structure, a rotating assembly, a positioning assembly, and locking components. The support structure serves as the foundation, stably supporting the fire monitor and ensuring its stability during operation. The rotating assembly typically includes a rotatable shaft, bearings, and connecting parts, allowing the fire monitor to be adjusted in both horizontal and vertical directions to meet the fire extinguishing needs of fire sources from different locations.

[0003] Existing industrial fixed fire monitor spray angle positioning mechanisms typically employ two symmetrically arranged arc-shaped clamps to hold the water hose in place for positioning and angle adjustment. To enhance positioning stability, rubber strips are usually installed on the inner wall of the arc-shaped clamps, utilizing their flexibility and high friction. However, these rubber strips age and wear over time. Aged rubber strips lose elasticity, become brittle, and their friction is significantly reduced. Replacing these worn rubber strips is extremely troublesome. First, multiple fastening components connecting the arc-shaped clamps to the water hose need to be removed. These components may have rusted or become jammed due to long-term use, further complicating the removal process. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an industrial fixed fire monitor spray angle positioning mechanism to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an industrial fixed fire monitor spray angle positioning mechanism, including a support bend. The bottom of the support bend is rotatably connected to an installation base pipe via a rotary sealed bearing. The top of the support bend is fixedly connected to a transfer pipe via bolts. One end of the transfer pipe is rotatably connected to a spray pipe via a rotary sealed bearing. Two symmetrically arranged pins are fixedly connected to one side of the transfer pipe. An arc-shaped clamp is rotatably connected to the outer surface of each pin. The two arc-shaped clamps are connected by an adjusting screw. An assembly groove is formed on the inner wall of each arc-shaped clamp. An arc-shaped assembly plate is slidably connected to the inner wall of the assembly groove. An arc-shaped rubber strip is fixedly connected to the inner wall of the arc-shaped assembly plate. The inner walls of both arc-shaped rubber strips are in contact with the outer surface of the spray pipe. A locking bolt is rotatably connected to one side of each arc-shaped clamp. The screw portions of the two locking bolts are threadedly connected to the two arc-shaped assembly plates respectively.

[0007] Preferably, in any of the above embodiments, a locking sleeve is fixedly connected to the outer surface of the supporting bend, and an adjusting bolt is threadedly connected to one side of the locking sleeve, with the threaded part of the adjusting bolt fitting against the mounting base tube.

[0008] Preferably, one side of the supporting bend is fixedly connected to a connecting plate, and the outer surface of the spray pipe is fixedly connected to a rotating shaft, which is rotatably connected to the connecting plate.

[0009] Preferably, in any of the above solutions, a threaded hole is provided on the outer surface of each of the arc-shaped assembly plates, and the screw portions of the two locking bolts are threadedly connected to the two arc-shaped assembly plates through the threaded hole.

[0010] Preferably, one side of the arc-shaped assembly plate is fixedly connected with two symmetrically arranged positioning pins, and the inner wall of the assembly groove is provided with positioning holes, with the two positioning pins respectively inserted into the two positioning holes.

[0011] Preferably, in any of the above embodiments, the left and right ends of the arc-shaped assembly plate are fixedly connected to sliding supports, and the inner wall of the assembly groove has two symmetrically arranged sliding grooves, and the sliding supports are slidably connected to the arc-shaped clamps through the sliding grooves.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. When the arc-shaped rubber strip ages or wears, there is no need to disassemble the arc-shaped clamp and the spray pipe. Simply unscrew the locking bolt to disengage it from the threaded hole of the arc-shaped assembly plate. Then, push the arc-shaped assembly plate to make it slide along the groove of the assembly slot, and the positioning pin will disengage from the positioning hole. The arc-shaped assembly plate and the arc-shaped rubber strip can then be removed from the assembly slot. To replace the new arc-shaped assembly plate, push it into the assembly slot through the cooperation of the sliding plate and the groove, so that the positioning pin is inserted into the positioning hole. Finally, tighten the locking bolt to fix it. Through the sliding cooperation between the arc-shaped assembly plate and the assembly slot, combined with the quick disassembly and assembly of the locking bolt, the arc-shaped rubber strip can be replaced independently without removing the connecting parts of the arc-shaped clamp and the spray pipe. This avoids the problems of rusting and jamming, and clamp damage caused by the removal of fastening parts in traditional designs. The cooperation between the positioning pin and the positioning hole, and between the sliding plate and the groove, ensures that the arc-shaped assembly plate is installed accurately, ensuring that the arc-shaped rubber strip and the spray pipe fit tightly and maintain stable friction. This solves the problems of troublesome rubber strip replacement and reduced positioning effect, improving maintenance efficiency and the long-term reliability of the mechanism.

[0013] 2. When adjusting the spray angle, loosen the adjusting screw of the arc-shaped clamp and the adjusting bolt of the locking sleeve, pushing the spray pipe to rotate around the rotary sealed bearing of the transfer pipe. Simultaneously, the support bend can rotate around the mounting base pipe. During rotation, the spray pipe's rotation axis rotates along the connecting plate, ensuring smooth angle adjustment. Once the angle is adjusted to the correct position, tighten the adjusting bolt to fix the support bend to the mounting base pipe. Then, tighten the two arc-shaped clamps by adjusting the screw, causing the arc-shaped rubber strip to grip the spray pipe, completing the positioning. The rotational cooperation between the support bend and the mounting base pipe achieves horizontal angle adjustment, while the rotational cooperation between the spray pipe and the transfer pipe achieves vertical angle adjustment. This dual-rotation structure improves the adjustment range of the fire monitor's spray angle, allowing for precise response to fire sources at different heights and directions. The cooperation between the rotating shaft and the connecting plate enhances the stability of the spray pipe during rotation, preventing swaying from affecting angle positioning accuracy. The double locking of the adjusting bolt and the arc-shaped clamp ensures that the mechanism does not loosen under water flow impact after positioning, guaranteeing consistent spray angles during firefighting and improving firefighting adaptability in complex industrial scenarios.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0017] like Figures 1 to 5 As shown, an industrial fixed fire monitor spray angle positioning mechanism includes a support bend 1. The bottom of the support bend 1 is rotatably connected to a mounting base pipe 2 via a rotary sealed bearing. The top of the support bend 1 is fixedly connected to a transfer pipe 3 via bolts. One end of the transfer pipe 3 is rotatably connected to a spray pipe 4 via a rotary sealed bearing. Two symmetrically arranged pins 5 are fixedly connected to one side of the transfer pipe 3. An arc-shaped clamp 6 is rotatably connected to the outer surface of each pin 5. The two arc-shaped clamps 6 are connected to each other via an adjusting screw. An assembly groove 7 is opened on the inner wall of each arc-shaped clamp 6. An arc-shaped assembly plate 8 is slidably connected to the inner wall of the assembly groove 7. An arc-shaped rubber strip 9 is fixedly connected to the inner wall of the arc-shaped assembly plate 8. The inner walls of the two arc-shaped rubber strips 9 are in contact with the outer surface of the spray pipe 4. A locking bolt 10 is rotatably connected to one side of each arc-shaped clamp 6. The screw parts of the two locking bolts 10 are threadedly connected to the two arc-shaped assembly plates 8 respectively.

[0018] As an optional technical solution of this utility model, a locking sleeve 11 is fixedly connected to the outer surface of the supporting bend 1. An adjusting bolt 12 is threadedly connected to one side of the locking sleeve 11. The screw part of the adjusting bolt 12 is in contact with the mounting base tube. When the supporting bend 1 rotates around the mounting base tube 2 to the required horizontal angle, the adjusting bolt 12 is tightened so that its screw part is tightly in contact with the mounting base tube. This can quickly lock the position of the supporting bend 1, preventing it from rotating due to the reaction force of the water flow during the spraying process, ensuring the stability of the horizontal spray angle. At the same time, the threaded connection makes it easy to flexibly adjust the locking force, and the operation is simple and convenient.

[0019] As an optional technical solution of this utility model, a connecting plate 13 is fixedly connected to one side of the supporting bend 1, and a rotating shaft 19 is fixedly connected to the outer surface of the spray pipe 4. The rotating shaft 19 is rotatably connected to the connecting plate 13, providing an additional support point for the rotation of the spray pipe 4, making the spray pipe 4 more stable when adjusting the vertical angle around the rotating pipe 3, avoiding shaking or deviation caused by uneven force, improving the accuracy of vertical angle adjustment, and ensuring that the spray pipe 4 can stably stay at the preset angle.

[0020] As an optional technical solution of this utility model, each arc-shaped assembly plate 8 has a threaded hole 14 on its outer surface. The screws of the two locking bolts 10 are threadedly connected to the two arc-shaped assembly plates 8 through the threaded holes 14. After the arc-shaped assembly plate 8 is installed into the assembly slot 7, it can be firmly fixed to the arc-shaped clamp 6 by the locking bolts 10 to prevent the arc-shaped assembly plate 8 from loosening or falling off during use, and to ensure that the arc-shaped rubber strip 9 is always in close contact with the spray pipe 4. At the same time, the threaded connection facilitates quick disassembly and assembly, and provides convenience for the replacement of the arc-shaped assembly plate 8 and the arc-shaped rubber strip 9.

[0021] As an optional technical solution of this utility model, two symmetrically arranged positioning pins 15 are fixedly connected to one side of the arc-shaped assembly plate 8. The inner wall of the assembly groove 7 is provided with positioning holes 16. The two positioning pins 15 are respectively inserted into the two positioning holes 16, which can accurately position the arc-shaped assembly plate 8 when it is installed, ensuring that the relative position of the arc-shaped assembly plate 8 and the arc-shaped clamp 6 is accurate, so that the arc-shaped rubber strip 9 can evenly fit the surface of the spray pipe 4, avoiding the local loose fit caused by assembly offset, which affects the positioning effect, and improving the assembly accuracy and stability.

[0022] As an optional technical solution of this utility model, the left and right ends of the arc-shaped assembly plate 8 are fixedly connected with slides 17. The inner wall of the assembly groove 7 is provided with two symmetrically arranged slide grooves 18. The slides 17 are slidably connected to the arc-shaped clamps 6 through the slide grooves 18, providing a guide track for the installation and disassembly of the arc-shaped assembly plate 8, so that the arc-shaped assembly plate 8 can smoothly enter and exit the assembly groove 7 along a fixed path, avoiding jamming or misalignment during installation. At the same time, the limiting effect of the slide grooves 18 on the slides 17 can prevent the arc-shaped assembly plate 8 from shifting laterally during use, further ensuring the stability of the structure.

[0023] An industrial fixed fire monitor spray angle positioning mechanism, the working principle of which is as follows: 1) When the arc-shaped rubber strip 9 ages or wears out, there is no need to remove the connection between the arc-shaped clamp 6 and the spray pipe 4. Just unscrew the locking bolt 10 to disengage it from the threaded hole 14 of the arc-shaped assembly plate 8.

[0024] 2): Push the arc-shaped assembly plate 8 so that it drives the slide 17 to slide along the slide groove 18 of the assembly groove 7. The positioning pin 15 will disengage from the positioning hole 16, and the arc-shaped assembly plate 8 together with the arc-shaped rubber strip 9 can be removed from the assembly groove 7.

[0025] 3): Replace the new arc-shaped assembly plate 8, push it into the assembly groove 7 through the cooperation of the slide 17 and the slide groove 18, so that the positioning pin 15 is inserted into the positioning hole 16, and finally tighten the locking bolt 10 to fix it.

[0026] In summary, when the arc-shaped rubber strip 9 ages or wears out, the arc-shaped clamp 6 does not need to be disconnected from the spray pipe 4. Simply unscrew the locking bolt 10 to disengage it from the threaded hole 14 of the arc-shaped assembly plate 8; then push the arc-shaped assembly plate 8 so that it drives the sliding bracket 17 to slide along the slide groove 18 of the assembly groove 7, and the positioning pin 15 disengages from the positioning hole 16, so that the arc-shaped assembly plate 8 together with the arc-shaped rubber strip 9 can be removed from the assembly groove 7; replace the new arc-shaped assembly plate 8, push it into the assembly groove 7 through the cooperation of the sliding bracket 17 and the slide groove 18, so that the positioning pin 15 is inserted into the positioning hole 16, and finally tighten the locking bolt 10 to fix it. By sliding the arc-shaped assembly plate 8 and the assembly groove 7 together, and with the quick disassembly and assembly of the locking bolt 10, the arc-shaped rubber strip 9 can be replaced independently without removing the connecting parts between the arc-shaped clamp 6 and the spray pipe 4. This avoids problems such as rusting and jamming, and clamp damage caused by removing fastening parts in traditional designs. The cooperation between the positioning pin 15 and the positioning hole 16, and between the sliding bracket 17 and the sliding groove 18, ensures that the arc-shaped assembly plate 8 is installed accurately, ensuring that the arc-shaped rubber strip 9 and the spray pipe 4 fit tightly and maintain stable friction. This solves the problems of troublesome rubber strip replacement and reduced positioning effect, and improves maintenance efficiency. To ensure efficiency and long-term reliability of the mechanism, when adjusting the spray angle, loosen the adjusting screw of the arc-shaped clamp 6 and the adjusting bolt 12 of the locking sleeve 11, and push the spray pipe 4 to rotate around the rotary sealing bearing of the transfer tube 3. At the same time, the support bend 1 can rotate around the mounting base tube 2. During the rotation, the rotating shaft 19 of the spray pipe 4 rotates along the connecting plate 13 to ensure smooth angle adjustment. After the angle is adjusted to the correct position, tighten the adjusting bolt 12 to fix the support bend 1 to the mounting base tube 2, and then tighten the two arc-shaped clamps 6 by adjusting the screw to make the arc-shaped rubber strip 9 hug the spray pipe 4 to complete the positioning. The rotational cooperation between the support bend 1 and the mounting base 2 enables horizontal angle adjustment, while the rotational cooperation between the spray pipe 4 and the adapter pipe 3 enables vertical angle adjustment. This dual-rotation structure enhances the adjustment range of the fire monitor's spray angle, allowing for precise response to fire sources at different heights and directions. The cooperation between the rotating shaft 19 and the connecting plate 13 strengthens the stability of the spray pipe 4 during rotation, preventing swaying from affecting the angle positioning accuracy. The dual locking of the adjusting bolt 12 and the arc-shaped clamp 6 ensures that the mechanism does not loosen under the impact of water flow after positioning, guaranteeing the consistency of the spray angle during firefighting and improving the firefighting adaptability in complex industrial scenarios.
