Detailed Description
The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.
The utility model provides a subway tunnel contact passageway supports platform truck fast, includes platform truck 11, multiunit bracing piece 4, bracing piece jack, bracing piece round pin axle 5, round pin axle elevating system, at the bracing piece epaxial, even interval suit multiunit bracing piece, every group bracing piece is two and cross arrangement, an cambered surface backup pad 1, the equal installation of lower extreme of all installing of upper end of each bracing piece, a plane backup pad 13. And a supporting rod retracting mechanism is arranged at the lower part between the two supporting rods of each group and is used for controlling the angle between the two supporting rods of each group. And two ends of the pin shaft of the support rod are respectively provided with a pin shaft lifting mechanism for lifting the height of the support rod.
The pin shaft lifting mechanism is a lifting hydraulic cylinder 7, the lifting hydraulic cylinder is vertically arranged on the top surface of the trolley, and the piston end of the lifting hydraulic cylinder is connected with a pin shaft.
The cambered surface supporting plate is connected with the supporting rod through a telescopic mechanism. The telescopic mechanism is a hydraulic cylinder 3, the base of the hydraulic cylinder is fixedly welded with the upper end of the supporting rod, and the piston end of the hydraulic cylinder is connected with the cambered surface supporting plate through a spherical hinge support 2. The plane supporting plate is connected with the lower end of the supporting rod through a spherical hinge support.
The support rod retracting mechanism comprises two slidable hydraulic cylinders 10 which are slidably mounted in a slide rail 12 which is formed on the top surface of the trolley. The piston ends of the two slidable hydraulic cylinders are respectively connected with the lower parts of the two supporting rods in the same group through a spherical hinge support 8. And a lower locking mechanism is connected between the two slidable hydraulic cylinders, the lower locking mechanism is a cross type telescopic frame 9, and the lower locking mechanism is locked after a proper angle between the two supporting rods in the same group is found.
Locking mechanism is installed on upper portion between two bracing pieces of every group for inject the upper portion angle between two bracing pieces of the same group, locking mechanism include two connecting rods 6, the one end hinge dress of two connecting rods, two bracing pieces of the same group are connected respectively to the other end of two connecting rods.
The connection channel is a straight wall circular arch structure and comprises an arch part 16 and a straight wall part 17, and the mechanism is provided with an arc surface supporting plate which is used for supporting the upper arch structure of the connection channel and a plane supporting plate which is used for supporting a straight wall respectively on the basis of the trolley according to the characteristics.
On the underside of the trolley is mounted a tank 15 which is connected to the trolley via a pipe 14 and then flows to the individual cylinders.
The working principle of the mechanism is as follows:
in order to improve the stress condition of the shield connecting channel and prevent the segment from deforming, the support trolley drives into a support place through the track of the trolley to support. The angle of the lower part of each group of support rods is adjusted by the sliding of the support rod retraction mechanism, when the two slidable hydraulic cylinders slide to the two ends, the angle between the two support rods of the same group is reduced, and when the slidable hydraulic cylinders move to the middle, the angle between the two support rods of the same group is increased. In order to prevent the slidable hydraulic cylinder from sliding arbitrarily, the lower locking mechanism is used for controlling the slidable hydraulic cylinder.
After the cambered surface backup pad contacted the domes of contact passageway, the plane backup pad contacted contact passageway vertical wall structure, perhaps if because of the high height that the contact passed through too high, the backup pad supported, can realize the improvement of bracing piece height through round pin axle elevating system, until reaching suitable height. The supporting plate is in better contact with the communication channel under the action of the spherical hinge support, and then the supporting rod is fixed at a certain position under the action of the locking mechanism and does not slide any more.
The height supported by the mechanism is about 4-5 meters, the width is about 3-4 meters, and the mechanism can be suitable for most communication channels. After the mechanism completes the supporting operation, the locking effect of the locking mechanism is released, the slidable hydraulic cylinder moves towards the middle, then the hydraulic cylinder contracts, the width is nearly 3 meters and 2 meters after the sliding hydraulic cylinder is folded, and finally the trolley mechanism is driven out along the track 18.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the spirit of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
