Description
Technical field
The utility model relates to technical field of engineering machinery, and what be specifically related to is a kind of prevention shield machine mud door drop device.
Background technology
In prior art, shield machine mud door present position environment in tunneling process is relatively disliked slightly, in the situation that may occur the phenomenon of mud door oil pipe or oil cylinder breakage and cause mud Men Wei to operate, close, often need warehouse entry with pressure to carry out repair, also have numerous items for preventing that mud door from falling, just mud door need be welded before construction, to construction, bring tremendous influence like this.
Utility model content
In order to overcome defect of the prior art, the utility model provides a kind of prevention shield machine mud door drop device can prevent that mud door from falling, and the mud door to shield machine in tunneling process forms second protection.
The utility model is achieved by the following technical solution: a kind of prevention shield machine mud door drop device, comprise and be arranged on mud door on the dividing plate of air cushion storehouse, be rigidly connected one end of mud door oil cylinder of described mud door, other one end of described mud door oil cylinder is connected with air cushion storehouse dividing plate, also be included in the first hanger that described air cushion storehouse dividing plate is provided with, described the first hanger is connected with one end of auxiliary cylinder, the other end of described auxiliary cylinder is connected by withholding with wire rope, the other end of described wire rope is connected with the second hanger on described mud door, described auxiliary cylinder is connected with oil hydraulic power control system.
Further, the stroke of described auxiliary cylinder is 1 meter.
Further, described device is provided with 2 groups on air cushion storehouse dividing plate 7.
Compared with prior art, superior effect is: when the utility model can mud door falls in shield machine tunneling process, bring into play the effect of second protection.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Reference numeral is as follows:
1-the first hanger, 2-auxiliary cylinder, 3-shackle, 4-wire rope, 5-the second hanger, 6-mud door, 7-air cushion storehouse dividing plate, 8-mud door oil cylinder.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model specific embodiment is described in further detail.
Embodiment 1
In conjunction with Figure of description 1, illustrate the utility model, the utility model provides a kind of prevention shield machine mud door drop device, comprise and be arranged on mud door 6 on air cushion storehouse dividing plate 7, be rigidly connected one end of mud door oil cylinder 8 of described mud door 6, other one end of described mud door oil cylinder 8 is connected with air cushion storehouse dividing plate 7, also be included in the first hanger 1 that described air cushion storehouse dividing plate 7 is provided with, described the first hanger 1 is connected with one end of auxiliary cylinder 2, the other end of described auxiliary cylinder 2 is connected with wire rope 4 by withholding 3, the other end of described wire rope 4 is connected with the second hanger 2 on described mud door 6, described auxiliary cylinder 2 is connected with oil hydraulic power control system, the stroke of described auxiliary cylinder 2 is 1 meter, described device is provided with 2 groups at air cushion storehouse dividing plate 7, specifically be set to two the first hangers 1 of correct position welding on the dividing plate 7 of air cushion storehouse, loading onto respectively stroke is the auxiliary cylinder 2 of 1m, in shield machine inside, new control system being set controls auxiliary cylinder 2, under normal condition, auxiliary cylinder 2 is in retracted state, normal pressure warehouse entry maybe need to carry out air cushion storehouse check work constantly mud door oil cylinder 8 stretch out with auxiliary cylinder 2 simultaneously, reach the effect of dual control mud door, when mud door falls in shield machine tunneling process, bring into play the effect of second protection.
The utility model is not limited to above-mentioned embodiment, and in the situation that not deviating from flesh and blood of the present utility model, any distortion it may occur to persons skilled in the art that, improvement, replacement all fall into scope of the present utility model.
