Abstract
The utility model discloses a liftable driver cab ceiling for a tunnel drill machine, which comprises a ceiling, a column for supporting the ceiling and a hollow guide column. A lifting rack is arranged at the middle lower portion of the column, the lifting rack is movably inserted in the guide column, and a clamp lock mechanism for clamping the lifting rack is arranged at the upper end of the guide column. The liftable driver cab ceiling for the tunnel drill machine has the advantages of being capable of being lifted, widening view of drivers and meeting requirements for height.
Description
Technical field
The utility model relates to a kind of ceiling, and particularly a kind of have ceiling elevating function, that be used for the tunnel boring machine drivers' cab.
Background technology
Existing tunnel all is fixed with the ceiling of rig, can not go up and down.Because the factor that the rig action need is observed in the tunnel is a lot, the driver needs broad view, so need the drivers' cab ceiling that certain height is arranged.But be subject to the height through tunnel lower and tunnel lining trolley bottom, the tunnel is strict restriction with the height of rig, has used a lot of inconvenient parts.
The utility model content
The goal of the invention of the utility model is, a kind of can go up and down, ceiling of being used for the tunnel boring machine drivers' cab is provided, to solve ceiling the inconvenient part in practical application of existing tunnel with rig.
The technical scheme that the utility model adopts is such: a kind of liftable tunnel is with rig drivers' cab ceiling; The column that comprises ceiling and support ceiling; Also comprise a hollow guide upright post; Said column middle and lower part is provided with lifter rack, and this lifter rack section activity is inserted in the guide upright post, and said guide upright post upper end is provided with the locking mechanism that blocks the lifter rack section.
As optimal way; Said locking mechanism comprises rotary fixed strip on the fixed block that is fixedly connected with guide upright post and spring, the fixed block; Said spring one end connects fixed strip; The spring other end of lifter rack section dorsad is fixedly connected on the fixed block, and the free end of said fixed strip is stuck on the tooth of lifter rack section.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is: can go up and down, both can the open driver visual field, and can satisfy the requirement on the height again.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Mark among the figure: 1 is ceiling, and 2 is column, and 21 is the lifter rack section, and 3 is locking mechanism, and 31 is fixed strip, and 32 is spring, and 4 is guide upright post.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
As shown in Figure 1; A kind of liftable tunnel is with rig drivers' cab ceiling; Comprise ceiling 1 and support the column 2 of ceiling 1 that also comprise a hollow guide upright post 4, said column middle and lower part is provided with lifter rack 21; These lifter rack section 21 activities are inserted in the guide upright post 4, and said guide upright post 4 upper ends are provided with the locking mechanism 3 that blocks lifter rack section 21.
Said locking mechanism 3 comprises rotary fixed strip 31 on the fixed block that is fixedly connected with guide upright post 4 and spring 32, the fixed block; Said spring one end connects fixed strip 31; Spring 32 other end of lifter rack section 21 dorsad is fixedly connected on the fixed block, and the free end of said fixed strip 31 is stuck on the tooth of lifter rack section 21.
The utility model can also be employed in column 2 lower ends and be fixedly connected hydraulic jack, regulates the height of ceiling 1 through stretching of hydraulic jack.
