Abstract
The invention discloses a protecting device of a shield machine thrust oil cylinder, which comprises the thrust oil cylinder arranged on a shield machine body, wherein the front part of the thrust oil cylinder is connected with a middle shield flange on the shield machine body; the rear part of the thrust oil cylinder is supported through a middle shield back supporting plate on the shield machine body; the front part of the thrust oil cylinder is connected with the middle shield flange through a hinge ball head; an oil cylinder fixing plate is arranged on the rear part of the thrust oil cylinder; a plurality of supporting oil cylinders are arranged around the oil cylinder fixing plate; positioning blocks are welded at the positions, corresponding to the supporting oil cylinders, on the middle shield back supporting plate; and oil cylinder rods of the supporting oil cylinders are supported on the positioning blocks. When a shield turns, a certain included angle is formed between a tube piece axial line and a shield axial line, the thrust oil cylinder rotates around a front part hinge point under the action of a thrust component force, and the supporting oil cylinder in the corresponding direction on the rear part is driven to retract at the same time, so the axial line of the thrust oil cylinder is still overlapped with the central line of the side edge of a tube piece, the thrust oil cylinder does not bear a lateral force of the tube piece and can be freely extended, and then the thrust oil cylinder is protected.
Description
Technical field
The invention belongs to the tunnel construction equipment technical field, be specifically related to a kind of protecting device of shield machine thrust oil cylinder.
Background technology
In recent years, shield-tunneling construction affects the characteristics such as little, that driving speed is fast, ground settlement is little with it to ground and underground environment, is widely used in the subterranean tunnel construction.Propelling cylinder is the key components of shield machine, install the propelling of whole shield structure, attitude adjustment, section of jurisdiction is all to realize by propelling cylinder or under the cooperation of propelling cylinder, propelling cylinder will be in case damage will cause very big impact to equipment performance, construction period.The propelling cylinder that uses at present supports and mostly is greatly rigid support, and when the shield structure was turned, section of jurisdiction axis and shield structure axis had certain angle, and propelling cylinder is subject to lateral force, and is larger to the oil cylinder damage.
Summary of the invention
The objective of the invention is the problem of propelling cylinder because being subjected to lateral force to occur damaging in order to solve the shield structure and to turn, proposed a kind of protecting device of shield machine thrust oil cylinder.
Realize that the technical scheme that the object of the invention adopts is: protecting device of shield machine thrust oil cylinder comprises the propelling cylinder that is located on the shield machine body, the front portion of propelling cylinder is connected with middle shield flange on the shield machine body, and the rear portion is supported by the middle shield rear bearing sheet on the shield machine body; The front portion of described propelling cylinder is connected with middle shield flange by hinged bulb, the rear portion is provided with the oil cylinder fixed head, be provided with several support cylinders around the oil cylinder fixed head, be welded with locating piece with described support cylinder corresponding position on middle shield rear bearing sheet, the cylinder rod of support cylinder is supported on locating piece.
When the section of jurisdiction is installed, support cylinder in the present invention is in running order, propelling cylinder is parallel with shield structure axis in the effect lower axis of support cylinder, due to section of jurisdiction axis and the dead in line of shield structure when mounted, the axis of propelling cylinder overlaps with the center line of section of jurisdiction side so, and propelling cylinder support boots just in time withstand on the centre of section of jurisdiction side.In tunneling process, support cylinder quits work, and propelling cylinder is in quick condition.When the shield structure is turned; section of jurisdiction axis and shield structure axis have certain angle; propelling cylinder rotates around anterior pin joint under the effect of its propelling component; force simultaneously the support cylinder retraction on the respective direction of rear portion; the propelling cylinder axis still overlaps with the center line of section of jurisdiction side like this; propelling cylinder can freely not stretched by the lateral force of section of jurisdiction, reaches the protective effect to self.
The present invention will be further described below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the schematic diagram of the propelling cylinder in the present invention when installing in the section of jurisdiction.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the schematic diagram of the propelling cylinder in the present invention when rotating.
Fig. 4 is the B--B sectional view of Fig. 3.
Shield flange in 1. in figure, 2. hinged bulb, 3. propelling cylinder, 4 oil cylinder fixed heads, 5. support cylinder, 6. locating piece, 7. in shield rear bearing sheet, 8. propelling cylinder support boots, 9. section of jurisdiction, 10. shield machine body.
The specific embodiment
see Fig. 1, Fig. 2, protecting device of shield machine thrust oil cylinder, comprise the propelling cylinder 3 that is located on shield machine body 10, the front portion of propelling cylinder 3 is equipped with hinged bulb 2, hinged bulb 2 is bolted on the middle shield flange 1 of shield machine body 10, the rear portion of propelling cylinder 3 is equipped with oil cylinder fixed head 4, the surrounding of oil cylinder fixed head 4 is separately installed with six support cylinders 5, wherein go up, lower each two, each of left and right, the middle shield rear bearing sheet 7 that is located on shield machine body 10 is passed at the rear portion 3 of propelling cylinder, make the oil cylinder fixed head 4 on it close with middle shield rear bearing sheet 7, support cylinder 5 corresponding position with oil cylinder fixed head 4 on middle shield rear bearing sheet 7 is welded with locating piece 6, the cylinder rod of support cylinder 5 is supported on locating piece 6.
When section of jurisdiction 9 was installed, support cylinder 5 was in running order, and cylinder rod stretches out, and propelling cylinder 3 its axis under the effect of support cylinder 5 is parallel with shield structure axis, and propelling cylinder support boots 8 just in time withstand on the centre of section of jurisdiction 9 sides.Do not adopt the existing propelling cylinder 3 of protective device; the shield structure is turned downwards in tunneling process; section of jurisdiction 9 axis and shield structure axis have an angle at vertical direction; owing to being rigid support; propelling cylinder 3 axis are parallel with shield structure axis all the time; cause propelling cylinder 3 axis and section of jurisdiction 9 axis that one angle is arranged, propelling cylinder 3 is subject to the lateral force from the section of jurisdiction, easily is damaged.As shown in Figure 3, in the present invention, owing to adopting protective device, propelling cylinder 3 rotates around anterior pin joint.As shown in Figure 4, because support cylinder 5 quits work, under the effect that advances component, propelling cylinder 3 just forces two support cylinders, 5 retractions that are positioned at the bottom.The axis of propelling cylinder 3 still keeps overlapping with the center line of section of jurisdiction side like this, and propelling cylinder 3 just can freely not stretched by the lateral force of section of jurisdiction 9, thereby reaches the protective effect to self.
