Description

Technical Field

[0001] The invention relates to the technical field of fire standpipe installation and construction, in particular to an auxiliary correction device for fire standpipe construction. Background Art

[0002] A fire riser is a vertical pipe that plays a key role in a building's fire protection system. When a fire occurs, the fire riser can quickly transport water from fire water sources (such as fire water pools, fire water pump connectors, etc.) to each floor of the building, providing fire-fighting water for indoor fire hydrants and other fire-fighting equipment. When installing the fire riser, first erect the riser, then correct the verticality of the riser so that the riser is in a vertical state. The two ends of the riser correspond to the interfaces of the horizontal pipe respectively, and sealing gaskets are installed at both ends of the riser. Finally, the flange of the riser and the flange on the horizontal pipe are fixed together with bolts and nuts.

[0003] In the prior art, when installing the fire riser, the construction workers stand on an electric lifting platform, hold one end of the fire riser and stand it up.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: This embodiment is intended to solve the problem that when installing the fire standpipe, the construction worker stands on the electric lifting platform, holds one end of the fire standpipe and stands it up. When the fire standpipe is docked and installed, the construction worker manually corrects the verticality of the standpipe. Since the fire standpipe is generally heavy, it is more difficult for the construction worker to erect and correct the fire standpipe. Please refer to Figures 1 to 9 An auxiliary correction device for fire vertical pipe construction includes a mobile base 101, an electric lifting platform 103 is arranged on the mobile base 101, a rotating plate 204 is rotatably installed on the electric lifting platform 103, and a first clamping mechanism 2100 for clamping the vertical pipe is arranged on the rotating plate 204. The first clamping mechanism 2100 includes a first clamping plate 206 and a second clamping plate 207 arranged on the rotating plate 204, and the first clamping plate 206 and the second clamping plate 207 clamp the vertical pipe together.

[0030] For details, please refer to Figure 1 A vertical rod 201 is installed on the mobile base 101, and a No. 1 rack 202 is installed on the top of the vertical rod 201. A fixed seat 205 is installed on the electric lifting platform 103. A rotating shaft 212 is rotatably installed on the fixed seat 205. The rotating shaft 212 is fixedly connected to the rotating plate 204. A No. 1 gear 203 for meshing with the No. 1 rack 202 is provided on the rotating shaft 212. When the No. 1 rack 202 meshes with the No. 1 gear 203, the rotating plate 204 rotates 90 degrees.

[0031] In the present embodiment: before the vertical pipe is installed, the construction personnel first install the vertical pipe horizontally on the rotating plate 204, and the first clamping plate 206 and the second clamping plate 207 clamp the vertical pipe. When the electric lifting platform 103 moves upward, the No. 1 rack 202 and the No. 1 gear 203 will be meshed, thereby driving the rotating plate 204 to rotate 90 degrees, and further driving the vertical pipe to rotate 90 degrees, so that the horizontally installed vertical pipe is erected. After the vertical pipe is erected, the construction personnel move the mobile base 101 to the vertical pipe installation location for installation. During this process, the construction personnel do not need to hold the vertical pipe to rotate it, which reduces the gravity burden of holding the vertical pipe, thereby saving manpower and improving the practicality of the device.

[0032] Embodiment 2: This embodiment aims to solve the problem that the vertical tube is easy to slip when it is fixed by the friction between the first clamping plate 206 and the second clamping plate 207 during rotation. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 9 The second clamping plate 207 is slidably installed on the rotating plate 204, and a fixed sleeve 303 is arranged on the side of the second clamping plate 207. A No. 1 piston plate 311 is slidably installed in the fixed sleeve 303. A moving rod 310 is installed at one end of the No. 1 piston plate 311. The moving rod 310 is fixedly connected to the second clamping plate 207. An airbag 301 is arranged on the electric lifting platform 103, and a one-way valve 219 is arranged at the air inlet of the airbag 301. A No. 1 pipe 208 is installed on the airbag 301, and one end of the No. 1 pipe 208 is connected to the fixed sleeve 303.

[0033] The one-way valve 219 is generally composed of a pipeline and a sealing plate hinged in the pipeline. The sealing plate can only rotate in one direction through a spring, thereby ensuring that the gas can only pass in one direction. The specific structure and principle of the one-way valve 219 are well known to technical personnel in this field and will not be elaborated here.

[0034] Also, please refer to Figure 7 A No. 2 gear 304 is installed at one end of the rotating shaft 212, and a No. 2 rack 307 is slidably installed on the electric lifting platform 103.

A pair of limiting plates 309 are provided. The pair of limiting plates 309 are located on both sides of the No. 2 rack 307. A pressure plate 308 is installed at one end of the No. 2 rack 307, and the pressure plate 308 is in conflict with the airbag 301.

[0035] In this embodiment: when the No. 1 rack 202 is meshed with the No. 1 gear 203, the No. 2 gear 304 drives the rotating shaft 212 to rotate, further driving the No. 2 gear 304 to rotate, the No. 2 gear 304 is meshed with the No. 2 rack 307, the No. 2 rack 307 moves toward the airbag 301, the pressure plate 308 squeezes the airbag 301, and the gas in the airbag 301 enters the fixed sleeve 303 through the No. 1 pipe 208. The gas pressure in the fixed sleeve 303 increases, thereby driving the No. 1 piston plate 311 to move, and finally the No. 1 piston plate 311 drives the second clamping plate 207 to move toward the first clamping plate 206 through the moving rod 310 to clamp the vertical pipe, thereby strengthening the clamping effect on the vertical pipe, making the process of turning from horizontal to vertical more stable, preventing the vertical pipe from sliding and falling during the rotation process, thereby increasing the reliability of the device.

[0036] Embodiment 3: This embodiment is intended to solve the problem that after the vertical pipe is erected, only a rough correction is achieved. During installation, the construction personnel also need to fine-tune the verticality of the vertical pipe. This embodiment is an improvement made on the basis of embodiment 2.

[0041] In addition, a No. 2 correction mechanism 4400 is arranged on the second clamping mechanism 2200. The No. 2 correction mechanism 4400 has the same arrangement as the No. 1 correction mechanism 4100.
