Description
Technical field
The utility model relates to shield machine apparatus fields, specifically design a kind of shield machine screw machine Anti-blocking device.
Background technique
Shield machine is mainly used in constructing tunnel, and screw machine is that the important dregs transmission of entire shield machine tunneling process is set
Standby, the reliable closing of Qian Nimen in emergency situations is to ensure equipment safety key factor, especially encounters the big soil layer of water content,
It is easy to happen and gushs, if preceding mud door promptly cannot be closed reliably, consequence is hardly imaginable.
Mud door is installed on the native storehouse plate outer bottom of shield body before current screw machine, and the dregs in tunneling process soil storehouse is piled up in
Bottom, entire preceding mud door lock door-plate is by dregs covering slag.
Current preceding mud door has following several disadvantages: gate sheet long period of soaking be easy to cause gate sheet raw in dregs
Rust corrosion, cutterhead stirring dregs process are also easy to that gate sheet is caused to wear.And dregs is piled up in bottom, is easy to block gate
Plate leads to not close.After closing, dregs overburden soil storehouse, it is big that gate is again turned on resistance, requires oil cylinder high.
Utility model content:
Prevent in view of the shortcomings of the prior art, the utility model provides the shield machine screw machine that a kind of structure is simple, safe and reliable
Stuck device guarantees that screw machine can be rapidly closed and open in emergency situations, and high reliablity, sealing effect is good, avoids
Dregs blocks gate and damage oil cylinder.
Technical problem to be solved in the utility model is realized using following technical scheme:
A kind of shield machine screw machine Anti-blocking device, including Door frame board, gate sheet, oil cylinder, sealing element and sealing clamp, institute
It states and offers mud inlet among Door frame board, the left and right sides edge of the Door frame board is provided with shifting chute and seal groove；The lock
Door-plate is provided with two pieces, and the gate sheet is slidably inserted into shifting chute from left and right sides of Door frame board；The sealing element is mounted on
In seal groove；The sealing clamp upper and lower ends are fixed on Door frame board, and the side of the sealing clamp resists sealing element；It is described
Oil cylinder one end connects gate sheet, and the other end is fixed on shield machine.
As a kind of optimization of the utility model, fixation hole is offered on the gate sheet.
As a kind of optimization of the utility model, the left and right side of the Door frame board is set as incline structure.
As a kind of optimization of the utility model, the gate sheet is connect by bolt with oil cylinder.
As a kind of optimization of the utility model, the Door frame board is hollow structure.
A kind of shield machine screw machine Anti-blocking device provided by the utility model has following beneficial effect:
(1) shield machine screw machine Anti-blocking device described in the utility model is installed in shield body, and Tu Cang is avoided to have foreign matter
In the case of, helical axis is stuck with gate；
(2) shield machine screw machine Anti-blocking device oil cylinder described in the utility model closes and opens gate, not by other
Resistance interference, can quick closedown and opening, high reliablity；
(3) shield machine screw machine Anti-blocking device sealing clamp described in the utility model can adjust compression degree, keep
To sealing element continuous extrusion, it is made to form reliable sealing to gate and doorframe sliding surface, sealing effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model shield machine screw machine Anti-blocking device；
Fig. 2 is the schematic diagram of internal structure of the utility model shield machine screw machine Anti-blocking device.
Appended drawing reference: 1, Door frame board；2, gate sheet；3, oil cylinder；4, sealing element；5, sealing clamp.
Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model:
It is shown in reference picture 1, Fig. 2, a kind of shield machine screw machine Anti-blocking device, including it is Door frame board, gate sheet, oil cylinder, close
Sealing and sealing clamp offer mud inlet among the Door frame board, and the left and right sides edge of the Door frame board is provided with movement
Slot and seal groove；The gate sheet is provided with two pieces, and the gate sheet is slidably inserted into shifting chute from left and right sides of Door frame board；
The sealing element is mounted in seal groove；The sealing clamp upper and lower ends are fixed on Door frame board, the side of the sealing clamp
Face resists sealing element；Described oil cylinder one end connects gate sheet, and the other end is fixed on shield machine.
Specifically, the shield machine screw machine Anti-blocking device of above-described embodiment is installed in shield body, Tu Cang is avoided to have foreign matter
In the case of, helical axis is stuck with gate；And oil cylinder closes and opens gate, is not interfered by other resistances, can quick closedown
And opening, high reliablity；Sealing clamp can adjust compression degree simultaneously, keep to sealing element continuous extrusion, make it to gate and
Doorframe sliding surface forms reliable sealing, and sealing effect is good.
As a kind of optimization of the utility model, fixation hole is offered on the gate sheet.
As a kind of optimization of the utility model, the left and right side of the Door frame board is set as incline structure.
As a kind of optimization of the utility model, the gate sheet is connect by bolt with oil cylinder.
As a kind of optimization of the utility model, the Door frame board is hollow structure.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the utility model claims
Within the scope of.
