Embodiment 1

[0016] Example 1: Please refer to Figure 1-3 , the auxiliary fixing frame of the tunnel ventilation device, including a connection fixing plate 1, a support 6 and a ventilation device installation ring frame 8, the connection fixing plate 1 is installed and fixed on the top of the tunnel, and the connection fixing plate 1 is connected with the support 6 through the connecting column 2, The support 6 is provided with a circular frame 8 for installing a ventilation device, and the connecting fixed plate 1 is arc-shaped, which is convenient for dispersing force, ensures stability, is convenient to use, and improves safety.

[0017] Ventilation device is installed ring frame 8 tops to be connected with support 6 by pull rod 9, and pull rod 9 is auxiliary fixed, guarantees safety.

[0018] The top side wall of the bracket 6 is provided with a suspension ring 10, and the pulley fixed plate 13 is fixedly arranged on the top of the tunnel by a fixed bolt 14. The fixed pulley 12 is ar...

Embodiment 2

[0019] Embodiment two: On the basis of embodiment one, the ventilation device is installed with a buffer protection ring 17 inside the ring frame 8, and the side wall of the ventilation device is installed with a ring frame 8. The side wall is detachably provided with a blocking plate 20, and the ventilation device is installed on the The ventilation device is installed inside the ring frame 8 to ensure the work of the ventilation device, and the buffer protection ring 17 reduces the impact of friction on the ventilation device to ensure safety and improve the service life. Simultaneously, after the ventilation device is installed, the blocking plate 20 is installed to prevent the ventilation device from slipping out, so as to ensure safety and facilitate use.

[0020] Both ends of the connecting column 2 are provided with external threads, and the connecting column 2 is provided with multiple groups. The top of the connecting column 2 in the middle is connected with the connec...

Abstract

The invention discloses an auxiliary fixing frame of a ventilation device of a tunnel, and belongs to the field of tunnel peripheral equipment. The auxiliary fixing frame comprises a connecting fixingplate, a bracket and ventilation device mounting ring frames; the connecting fixing plate is fixedly mounted at the top of the tunnel and connected with the bracket through connecting columns, the bracket is provided with the ventilation device mounting ring frames, and the connecting fixing plate is arc; the side wall of the top of the bracket is provided with hanging rings, pulley fixing platesare provided with fixed pulleys, one end of a steel wire rope is fixed to each hanging ring, each steel wire rope penetrates through and winds the corresponding fixed pulley, and the other end of each steel wire rope is fixed to a winding fixing device. The auxiliary fixing frame facilitates force dispersion, ensures the stability, is convenient to use and improves the safety. The winding fixingdevices are rotated through hand cranks, the steel wire ropes are tightened, the force on the bracket is shared, the stability is ensured, and the auxiliary fixing frame is convenient to use; meanwhile, when the connecting fixing plate is loosened, the bracket is suspended by the steel wire ropes to prevent the situation that the bracket falls and hurts pedestrians or vehicles, the safety is improved, and the auxiliary fixing frame is convenient to use and facilitates popularization.

Description

technical field [0001] The invention relates to the field of tunnel peripherals, in particular to an auxiliary fixing frame for a tunnel ventilation device. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. The structure of the tunnel includes two parts, the main building and the auxiliary equipment. The main building is composed of the tunnel body and the tunnel door. The auxiliary equipment includes car avoidance tunnels, fire protection facilities, emergency communication and waterproof and drainage facilities. The long tunnel also has special ventilation and lighting equipment. The natural wind at the entrance and exit of the tunnel is far from enough. It must be equipped with a tunnel fan to transport and adjust the air or remove the smoke and dust of the cars passing in the tunne...
