Description
Technical Field
The utility model relates to the technical field of shield construction, in particular to a baffle for protecting a screw machine in a shield machine.
Background
The shield tunneling machine is a tunnel tunneling machine using a shield tunneling method, wherein a screw machine is used as an indispensable part of the shield tunneling machine, the borne work is to transport excavated muck and rock, but the shield tunneling machine inevitably encounters bad strata such as boulder stratum, upper soft and lower hard strata, full-section hard rock stratum and the like of an excavated soil layer, the bad strata are easy to generate larger rock when tunneling, and have bad abrasion to a cutter, and the cutter is easy to be seriously abraded, broken and other abnormal damages, and once the cutter and the rock are not found to enter the screw machine in time, the screw machine is seriously damaged, even can not normally operate, the construction progress and efficiency are greatly influenced, and the shield tunneling machine is extremely important for protecting the screw machine.
Disclosure of Invention
The utility model mainly aims to provide a baffle for protecting a screw machine in a shield machine so as to solve the problems in the prior art.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a baffle for protecting inside screw machine of shield constructs machine, includes two baffle bodies, the baffle body is installed on shield constructs the machine casing, two the baffle body is located the front end both sides of screw machine respectively, the bottom surface shape of baffle body and the shape assorted of shield structure machine casing, the top surface end department of baffle body sets up to the arc surface, the baffle body is close to one side of screw machine and sets up to the inclined plane, the baffle body is kept away from one side of screw machine and is set up to the ladder profile.
Further, the bottom surface, the arc surface and the inclined surface of the baffle body are smooth surfaces.
Further, the included angle between the step profile and the horizontal plane is more than 0 degrees and less than 30 degrees.
Further, the included angle between the inclined surface and the vertical surface is larger than 0 degrees and smaller than 30 degrees.
Further, the material of baffle body is powerful magnet.
Further, the highest point of the top surface of the baffle body and the screw shaft of the screw machine are positioned at the same height.
Compared with the prior art, the utility model has the following beneficial effects:
the baffle body is arranged on two sides of the front end of the screw machine, so that impact of sliding of side block stones or sudden falling of cutters on the screw machine is effectively prevented, the baffle body can absorb parts generated by cutter damage or falling cutters by adopting strong magnets, parts generated by cutter damage or falling cutters are prevented from damaging the screw machine, and meanwhile, the baffle is inspected periodically to remove adsorbed metal sundries in time; the contact surface of the baffle body and the excavated soil is a step-shaped surface, so that friction with the excavated soil is increased, and the excavated soil is further crushed; the baffle body is close to the screw machine one side and sets up to the inclined plane, is favorable to the motion of cutting out the soil.

Fig. 2 is a schematic view of a baffle body set position according to the present utility model.
Wherein, 1-baffle body, 2-ladder profile, 3-arc surface, 4-screw machine.
Detailed Description
The technical scheme of the utility model is further described below through the attached drawings and the embodiments.
Referring to fig. 1 to 2, the utility model provides a baffle for protecting a screw machine in a shield machine, which comprises two baffle bodies 1, wherein the baffle bodies 1 are arranged on a shield machine shell, and the two baffle bodies 1 are respectively positioned at two sides of the front end of the screw machine 4; the bottom surface of baffle body 1 is installed on shield machine casing, and its shape and shield machine casing's shape phase-match, the top surface end department of baffle body 1 sets up to arc surface 3, one side that baffle body 1 is close to screw machine 4 sets up to the inclined plane, one side that baffle body 1 kept away from screw machine 4 sets up to ladder profile 2.
In the embodiment, the baffle body 1 is adhered to the shield tunneling machine shell by using special metal glue and is positioned on two sides of the front end of the screw machine 4, so that the impact of side block stone falling or sudden cutter falling to the screw machine 4 is effectively prevented.
In this embodiment, the step profile 2 on the side far from the screw 4 is the contact surface with the excavated soil, and the included angle between the step profile and the horizontal plane is greater than 0 ° and less than 30 °. The friction with the excavated soil is increased by adopting the step profile 2, and the excavated soil is further crushed.
In this embodiment, the bottom surface, the arc surface 3 and the inclined surface of the baffle body 1 are smooth surfaces.
In this embodiment, the included angle between the inclined surface and the vertical surface is greater than 0 ° and less than 30 °. The inclined surface is beneficial to the movement of the excavated soil.
In this embodiment, the material of the baffle body 1 is a strong magnet. The magnet material can attract the parts generated by the cutter damage or the fallen cutter to prevent damage to the screw 4.
In this embodiment, the highest point of the top surface of the baffle body 1 is at the same height as the screw axis of the screw machine 4.
The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the technical scope of the present utility model, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model still fall within the scope of the technical solutions of the present utility model.
