Description
Technical Field
The utility model relates to a water inlet accident gate hydraulic cylinder dismounting device. The hydraulic cylinder assembly device is suitable for the technical field of installation and maintenance of hydraulic cylinders of accident gates of water inlets of hydropower stations.
Background
The high-head hydropower station is provided with a water inlet accident gate at the water inlet of the water diversion power generation system, when the water turbine generator set has a runaway accident and a water diversion pressure steel pipe rupture accident, the gate is quickly closed to cut off water flow, and the water turbine generator set or the water diversion pressure steel pipe is protected, so that the safe operation of the hydropower station plant and equipment is ensured, and the accident is reduced to the minimum; in order to ensure that the accident gate can be closed quickly in a short time, the hydraulic hoist structure is generally adopted for controlling the opening and closing, so that the safe and stable operation of the accident gate is directly related to the safe operation of the hydropower station.
The hydraulic cylinder is used as an important component of an accident gate, and in the overhaul of the hydraulic cylinder of each hydraulic power plant, the hydraulic cylinder is often required to be dismantled for returning to the plant for maintenance. The traditional hydraulic cylinder dismantling mode is that the hydraulic cylinder is lifted out of the door slot through the automobile jack, and the defect is that: because the hydraulic cylinder is heavy, a large-tonnage automobile crane with the weight of 50T or more is usually required to be used for lifting the hydraulic cylinder, when the hydraulic cylinder is lifted out of the door slot, the box needs to be turned over, and another automobile crane is required to be matched for turning over, so that the construction cost is greatly increased.
Disclosure of Invention
The utility model aims to solve the technical problems that: aiming at the problems, the dismounting device of the hydraulic cylinder of the water inlet accident gate is provided.
The technical scheme adopted by the utility model is as follows: a water inlet emergency gate hydraulic cylinder removal apparatus, comprising:
the hydraulic cylinder lifting mechanism adopts the existing gate door machine of the dam crest, and the action end of the gate door machine is provided with a connecting piece which can be connected with the lug plate at the top of the hydraulic cylinder to be disassembled;
the side support mechanism is provided with a hoop which is matched with the hydraulic cylinder to be disassembled and a support piece which is fixed on the side face of the hoop.
The support piece is far away from the hoop end and is provided with an arc tube piece.
The support piece is provided with two support plates which are parallel to each other and are connected to the side face of the anchor ear, the ends, far away from the anchor ear, of the two support plates are connected through a connecting plate, and the connecting plate is connected with the arc tube piece.
A plurality of reinforcing plates are connected between the two supporting plates.
The beneficial effects of the utility model are as follows: according to the utility model, the hydraulic cylinder can be lifted out of the gate well and turned over by utilizing the existing gantry crane to be matched with the side support mechanism, and a car crane is not required to be leased, so that the input cost of manpower and construction equipment is greatly reduced; the height of the water inlet door machine does not need to be too high, the steel consumption is reduced, and the purchase cost of the door machine is reduced;

Detailed Description
As shown in fig. 1, the embodiment is a water inlet accident gate hydraulic cylinder dismounting device, which is provided with a hydraulic cylinder lifting mechanism, a side supporting mechanism and the like.
In the embodiment, the hydraulic cylinder lifting mechanism adopts the existing gate door machine at the dam crest, and the action end of the gate door machine is provided with a connecting piece which can be connected with the lug plate at the top of the hydraulic cylinder to be disassembled.
As shown in fig. 2 and 3, in this embodiment, the side supporting mechanism includes a hoop adapted to the hydraulic cylinder to be disassembled and a supporting member fixed on the side of the hoop, where the supporting member includes two supporting plates parallel to each other and connected to the side of the hoop, and a plurality of reinforcing plates are connected between the two supporting plates, and the ends of the two supporting plates far away from the hoop are connected through a connecting plate, and the connecting plate is connected with a circular arc segment.
As shown in fig. 4, the working principle of the present embodiment is as follows:
the action end of the gate door machine descends into the gate well, and the action end is connected with the lug plate at the top of the hydraulic cylinder to be disassembled through a connecting piece;
the gate door machine lifts the hydraulic cylinder until the upper end of the hydraulic cylinder moves to the highest limit position of the action end of the gate door machine, and at the moment, the lower end of the hydraulic cylinder is still partially positioned in the gate well;
transversely moving a gate door machine, and moving a hydraulic cylinder suspended on the door machine to the edge of a gate well; fixing a side support mechanism on the hydraulic cylinder, wherein the fixing position of the side support mechanism is slightly higher than the top surface of the dam;
an auxiliary rope is fixed at the lower part of the cylinder body of the hydraulic cylinder in a crossing way, and two ends of the rope are respectively tensioned and fixed by a person, so that the hydraulic cylinder is prevented from swinging and sliding in the overturning process. Because the staple bolt volume is not big, people lift just can install when installing, and because there is the scaffold footboard in door slot position when installing, people's installation is safe.
Continuously transversely moving the gate door machine, gradually dumping the hydraulic cylinder after the hydraulic cylinder contacts with the gate well mouth until the outer arc surface of the arc segment of the side supporting mechanism on the hydraulic cylinder contacts with the dam crest; and continuously transversely moving the gate door machine and gradually lowering the action end of the gate door machine, so that the hydraulic cylinder is completely turned over by taking the side supporting mechanism as a support.
The above embodiments are only for illustrating the inventive concept of the present utility model and not for limiting the protection of the claims of the present utility model, and all the insubstantial modifications of the present utility model using the concept shall fall within the protection scope of the present utility model.
