Description

Technical Field

[0001] The invention relates to the technical field of pipeline support structures, in particular to a support structure applied to fire protection pipelines. Background Art

[0002] In the fire protection system, the installation and support of fire protection pipes are crucial links. Traditional fire protection pipe support structures often have problems such as complex installation, inconvenient height adjustment, and poor seismic performance. Especially when the height of the fire protection pipe needs to be adjusted, the traditional support structure often needs to be disassembled and reinstalled, which is cumbersome and inefficient. Even if it has a height adjustment structure, its traditional support structure can often only be adjusted individually, and it is impossible to adjust multiple groups of support structures synchronously. In addition, when natural disasters such as earthquakes occur, traditional support structures often cannot effectively buffer vibrations, causing the fire protection pipe to shake too much. Due to the rigid connection method, wear and tear may occur between the fire protection pipe and the support structure, causing damage to the fire protection pipe, seriously affecting the normal use of the fire protection system. Summary of the invention

[0003] In view of the problems in the prior art, the present invention provides a supporting structure for a fire protection pipeline.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a support structure applied to a fire-fighting pipe, comprising: a support frame with connecting rods installed at the four corners of the top; an adjusting seat and a clamping frame arranged above the support frame, the adjusting seat is used to adjust the height of the fire-fighting pipe, and the end thread of the clamping frame is connected to a nut for clamping the fire-fighting pipe; a mounting frame arranged above the support frame is used to connect to the wall; the support frame is a hollow structure, and cover plates are arranged at the openings at both ends of the support frame, a worm and a worm wheel are arranged inside the support frame, the worm between two adjacent support frames is connected by a flexible shaft, and the worm wheel is symmetrically arranged at the worm On both sides, the worm wheel is meshed with the worm, and a supporting sleeve is fixed in the center position of the worm wheel, and the internal thread of the supporting sleeve is inserted with a screw rod, and the screw rod movably passes through the supporting frame and is connected with the adjusting seat; a rubber plate and a supporting plate are sequentially arranged between the mounting frame and the adjusting seat from top to bottom, and the mounting frame and the supporting plate are connected by bolts and nuts, and the tops of the mounting frame and the supporting plate are penetrated by staggered through grooves, and the position of the above the rubber plate corresponding to the staggered through grooves is provided with staggered connecting spokes, and the tops of the staggered connecting spokes are inserted with bolts, and the bottoms of the bolts pass through the rubber plate and are threadedly connected to the connecting rod inserted into the staggered through grooves on the supporting plate.

[0005] Specifically, the flexible shaft consists of a flexible shaft body, a hose, a flexible shaft joint, and a hose joint. The flexible shaft body is located inside the hose. The flexible shaft joints are located at both ends of the flexible shaft body, pass through the cover plate movably, and are connected to the worm. The hose joints are located at both ends of the hose, and the hose joints are connected to the cover plate.

[0006] Specifically, support sleeves are fixed to both the top and bottom of the worm gear. The support sleeves are rotatably connected to the inner wall of the support frame for supporting the worm gear.

[0007] Specifically, the clamping frame includes an arc-shaped buckle frame arranged above the fire pipeline and a straight rod arranged at the bottom of the adjusting seat. The straight rod and the arc-shaped buckle frame are connected by a U-shaped connecting frame.

[0008] Specifically, grooves adapted to the connecting rods are provided at the four corners of the adjusting seat, and the adjusting seat is attached to the rod wall of the connecting rod through installation.

[0009] Advantages of the present invention:

[0010] (1) The support structure of the present invention realizes convenient adjustment of the height of the fire pipeline through the transmission mode of the worm and the worm gear. Just by driving the flexible shaft to rotate through an external motor, the worm and the worm gear can be driven to rotate synchronously, thereby realizing the lifting of the adjusting seat. The operation is simple and efficient, and multiple groups of support structures can be adjusted synchronously at the same time, making the heights of the fire pipelines after adjustment consistent.

[0011] (2) The support structure of the present invention is provided with a rubber plate between the mounting frame and the support frame, effectively buffering the impact of natural disasters such as earthquakes on the fire pipeline. The elastic characteristics of the rubber plate can absorb part of the vibration energy, prevent the fire pipeline from shaking greatly, and ensure the stability of the fire protection system.

[0012] (3) The support structure of the present invention is provided with a clamping frame on the adjusting seat, making the connection between the fire pipeline and the adjusting seat tight and easy to disassemble. This not only facilitates the installation and maintenance work, but also improves the versatility and adaptability of the support structure, and can be widely applied to different types of fire pipeline support scenarios.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 5 As shown, the present invention provides the following technical solutions:

[0022] Embodiment 1: A support structure for fire protection pipes, comprising: a support frame 1 with connecting rods 2 installed at the four corners of the top; an adjustment seat 10 and a clamping frame 11 arranged above the support frame 1, the adjustment seat 10 is used to adjust the height of the fire protection pipe, and the end of the clamping frame 11 is threaded with a nut 12 for clamping the fire protection pipe; a mounting frame 13 arranged above the support frame 1 is used to connect to the wall.

[0023] When in use, first, it can be installed on the wall by means of bolts set on the mounting frame 13, and the connecting rod 2 connects the support frame 1 and the mounting frame 13, then, the fire-fighting pipe is limited on the adjustment seat 10 by the clamping frame 11, and finally, when the support height of the fire-fighting pipe needs to be adjusted, the distance between the adjustment seat 10 and the support frame 1 can be adjusted, so that the height of the fire-fighting pipe can be adjusted after the installation is completed.

[0024] Embodiment 2: The technical solution of this embodiment is different from that of embodiment 1 and also includes that the support frame 1 is a hollow structure, and the openings at both ends of the support frame 1 are provided with cover plates 3, and the support frame 1 is provided with a worm 5 and a worm wheel 6 inside. The worm 5 between two adjacent support frames 1 is connected by a flexible shaft 4, and the worm wheel 6 is symmetrically arranged on both sides of the worm 5, and the worm wheel 6 is meshed with the worm 5. A support sleeve 7 is fixed at the center of the worm wheel 6, and the internal thread of the support sleeve 7 is inserted with a screw 9, and the screw 9 movably passes through the support frame 1 and is connected to the adjustment seat 10;

[0025] The flexible shaft 4 is composed of a flexible shaft body, a hose, a flexible shaft joint and a hose joint. The flexible shaft body is located inside the hose. The flexible shaft joints are located at both ends of the flexible shaft body, movably pass through the cover plate 3 and are connected to the worm 5. The hose joints are located at both ends of the hose, and the hose joints are connected to the cover plate 3.

[0026] The top and bottom of the worm gear 6 are both fixed with support sleeves 7, and the support sleeves 7 are rotatably connected to the inner wall of the support frame 1 to support the worm gear 6;

[0027] The four corners of the adjustment seat 10 are all provided with matching grooves corresponding to the connecting rod 2, and the adjustment seat 10 is fitted with the rod wall of the connecting rod 2 by installation, so that the adjustment seat 10 can be more stable when lifting.

[0028] When in use, the support frame 1 is supported by the mounting frame 13 in the same manner. In the initial state, the arrangement of the internal threaded sleeve 8 and the screw 9 can make the adjustment seat 10 more convenient when it needs to be lifted or lowered, and the arrangement of the worm 5 and the worm wheel 6 can self-lock it to prevent the adjustment seat 10 from accidentally lifting or lowering;

[0029] When the height of the fire-fighting pipe needs to be adjusted, the flexible shaft body is connected to the output end of the external motor. When the output end of the motor drives the flexible shaft 4 to rotate, the flexible shaft body can drive the worm 5 to rotate. Since the worms 5 in multiple supporting structures are synchronously connected through the flexible shaft body, the worms 5 in multiple supporting structures can rotate synchronously. When the worm 5 rotates, it can drive the worm wheel 6 to rotate and drive the adjustment seat 10 connected to the top of the screw rod 9 to rise and fall through the internal threaded sleeve 8. The lifting seats 10 inside the multiple supporting structures can synchronously drive the fire-fighting pipe to rise and fall, which can effectively avoid the problem of inconsistent lifting heights of the fire-fighting pipe.

[0030] Embodiment 3: The technical solution of this embodiment is different from that of Embodiment 2 and also includes that a rubber plate 14 and a support plate 15 are sequentially arranged between the mounting frame 13 and the adjustment seat 10 from top to bottom, and the mounting frame 13 and the support plate 15 are connected by bolts and nuts. The tops of the mounting frame 13 and the support plate 15 are penetrated by offset through grooves 17, and offset connecting spokes 16 are arranged above the rubber plate 14 at positions corresponding to the offset through grooves 17. Bolts are inserted at the tops of the offset connecting spokes 16, and the bottoms of the bolts pass through the rubber plate 14 and are threadedly connected to the connecting rod 2 inserted into the offset through grooves 17 on the support plate 15.

[0031] During use, after the mounting bracket 13 in the support structure is rigidly connected to the wall through bolts, if the mounting bracket 13 and the support frame 1 are also rigidly connected, when the mounting bracket 13 vibrates due to an earthquake, the fire pipeline provided on the support frame 1 will vibrate with the same amplitude. The rubber plate 14 provided can enable the mounting bracket 13 and the support frame 1 to be non-rigidly connected while still being stably connected, achieving a buffering effect and avoiding large-amplitude shaking of the fire pipeline and the support frame 1.

[0032] Embodiment 4: The technical solution of this embodiment different from that of Embodiment 3 further includes that the clamping bracket 11 includes an arc-shaped buckle provided above the fire pipeline and a straight rod provided at the bottom of the adjusting seat 10, and the straight rod and the arc-shaped buckle are connected by a U-shaped connecting frame.

[0033] During use, the arc-shaped buckle is buckled on the fire pipeline and slid along the fire pipeline, so that the straight rod is inserted into the bottom of the adjusting seat 10, and the U-shaped connecting frame abuts against the outer wall of the adjusting seat 10. Then, the nut 12 is threadedly sleeved on the end of the straight rod for locking. The clamping bracket 11 is locked on both sides of the adjusting seat 10 in the X-axis direction by the U-shaped connecting frame and the nut 12, and is resisted and clamped by the adjusting seat 10 in the Y-axis direction, so that the clamping bracket 11 can conveniently install and clamp the fire pipeline on the adjusting seat 10.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention.
