Description
Technical Field
The utility model relates to a construction field indicates a dryer linkage for shield tunnel especially.
Background
In the construction process of the subway shield tunnel, because the distance of the tunnel is generally longer, the earthing depth is large, and an air duct is usually required to be arranged at the top of the tunnel for air replacement.
In the prior art, a wind tube is connected and fixed with a duct piece bolt at the top by a thin iron wire. However, the thin iron wire is easy to deform, the air duct is easy to displace, and the position is unstable.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's defect, provide a dryer linkage for shield tunnel, it is fixed with the section of jurisdiction bolted connection at dryer and top to adopt thin iron wire among the solution prior art. But the thin iron wire is easy to deform, the air duct is easy to displace, and the position is unstable.
The technical scheme for realizing the purpose is as follows:
the utility model provides a dryer linkage for shield tunnel, include:
the hanging rope is fixed at the top of the tunnel along the direction of the tunnel;
the upper hooks are hung on the hanging rope and are arranged at intervals along the direction of the hanging rope;
the stabilizing frames are fixed at the bottoms of the corresponding upper hooks;
the lower hook is fixed at the bottom of the corresponding stabilizing frame and is arranged on the air duct, so that the air duct is hung on the tunnel.
The utility model discloses a dryer linkage's that is used for shield tunnel further improvement lies in, hang the relative both ends of rope around locating the end cap, through the end cap install in the injected hole in tunnel is realized it is fixed in to hang the rope the tunnel.
The utility model discloses a dryer linkage for shield tunnel's further improvement lies in, it is the regular triangle frame to stabilize the frame.
The utility model is further improved in the wind tube suspension device for the shield tunnel,
the upper hook is fixed at the upper vertex angle of the regular triangle frame;
the lower hook is fixed at the center of the bottom side of the regular triangle frame.
The utility model is used for shield tunnel's dryer linkage's beneficial effect:
the utility model discloses an adopt the stable frame to connect and go up couple and couple down, keep the stability of couple and couple position and shape down. In will hanging the rope and being fixed in the tunnel through adopting the end cap, avoid demolising the section of jurisdiction bolt, convenient operation, it is efficient. High-altitude operation is avoided, and construction is safe and reliable.

Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
Referring to fig. 1, a front view of the installation state of the wind tunnel suspension device for the shield tunnel of the present invention is shown. Fig. 2 is a side view of the installation state of the wind tunnel suspension device for the shield tunnel of the present invention. With reference to fig. 1 and 2, the utility model discloses a dryer linkage for shield tunnel includes:
a hanging rope 20 fixed on the top of the tunnel 10 along the running direction of the tunnel 10;
the hanging rope is provided with a plurality of upper hooks 30 hung on the hanging rope 20, and the upper hooks 30 are arranged at intervals along the trend of the hanging rope 20;
a stabilizing frame 40 fixed at the bottom of the corresponding upper hook 30;
and the lower hooks 50 are fixed at the bottoms of the corresponding stabilizing frames 40, and the lower hooks 50 are hooked on the air duct 60, so that the air duct 60 is hung on the tunnel 10.
As a preferred embodiment of the utility model, a dryer linkage for shield tunnel, hang the relative both ends of rope 20 around locating end cap 70, through end cap 70 install in the injected hole of tunnel 10 is realized it is fixed in to hang rope 20 tunnel 10.
Specifically, the lanyard 20 is an iron wire. When the plugs of the grouting holes are installed, the opposite two ends of the iron wire are wound on the tail parts of the corresponding plugs respectively, and the plugs are threaded and are similar to the principle of screwing screws and nuts. The plugs wound with iron wires are screwed into the corresponding grouting holes respectively to realize fixation. Convenient operation and fixed firm can avoid needing to twist off the section of jurisdiction bolt and install iron wire and bolt fixed among the prior art, the problem that the operating procedure is inefficiency more.
As a preferred embodiment of the present invention, the stabilizing frame 40 is a regular triangle frame. The regular triangle frame has stable structure, so that the upper hook 30 and the lower hook 50 are not easy to shake and have stable positions.
As a preferred embodiment of the air duct suspension device for the shield tunnel of the present invention, the upper hook 30 is fixed to the upper vertex angle of the regular triangle frame; the lower hook 50 is fixed to the center of the bottom side of the regular triangle frame. The upper hook 30 and the lower hook 50 are symmetrical up and down and are stable in position.
Fig. 3 is the utility model discloses an auxiliary frame for shield tunnel's dryer linkage. As shown in fig. 3, the auxiliary frame 80 includes a support groove and a stay fixed to the bottom of the support groove. The top of the stabilizing frame 40 is inserted through the supporting groove of the auxiliary frame, and the supporting rod is moved upwards, so that the upper hook is hung on the hanging rope, and a section of air duct is hung in the tunnel by using the auxiliary frame. The air duct is installed one section by one section, and the operation is convenient. Thereby avoid constructor to go up tunnel top high altitude construction through using the auxiliary frame, safe and reliable and convenient operation, it is efficient.
The utility model discloses a dryer linkage for shield tunnel's beneficial effect does:
the utility model discloses an adopt the stable frame to connect and go up couple and couple down, keep the stability of couple and couple position and shape down. In will hanging the rope and being fixed in the tunnel through adopting the end cap, avoid demolising the section of jurisdiction bolt, convenient operation, it is efficient. High-altitude operation is avoided, and construction is safe and reliable.
The present invention has been described in detail with reference to the embodiments shown in the drawings, and those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details of the embodiments should not be construed as limitations of the invention, which are intended to be covered by the following claims.
