Because the space in the top cover for disassembling and assembling the oil groove cover is limited, and the oil groove cover has the characteristics of large volume and mass, the oil groove cover can be lifted out by the combined force of multiple people, and the oil groove cover is easy to collide with people and equipment.
Disclosure of Invention
The utility model aims to solve the technical problems that: in order to overcome the defects in the prior art, the utility model provides the hydraulic generator upper guide bearing oil groove cover dismounting tool which is safe to use and convenient to operate.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a hydraulic generator goes up guide bearing oil groove lid assembly and disassembly tools, includes the crossbeam that sets up in generator top cover top, crossbeam below hoist and mount the slide rail that passes two adjacent side doors of top cover when having the dismouting, rolling installation has single track dolly on the slide rail, has hung the chain block below the end of single track dolly, the cover is equipped with the lug that can screw in the oil groove lid and lifts by crane the screw on the lower lifting hook of chain block.
Specifically, pull rods are respectively fixed on the upper planes of the two ends of the sliding rail, and the pull rods penetrate out of the upper end face of the cross beam and are fixed through locking nuts.
Further, limiting rods for controlling the monorail trolley to move out of the sliding rail are respectively fixed at two ends of the sliding rail.
The beneficial effects of the utility model are as follows: according to the utility model, the oil tank cover is lifted by the hand hoist, and is shifted by the monorail trolley, so that the operation is convenient, the danger of collision caused by narrow space and heavy oil tank cover in the manual carrying process can be avoided, and the operation safety and the dismounting efficiency of the oil tank cover are improved.
Drawings
The utility model will be further described with reference to the drawings and embodiments.
Fig. 1 is a schematic diagram of the front view structure of the present utility model.
Fig. 2 is a right-side view of the present utility model.
In the figure: 1. the device comprises a cross beam, a sliding rail, a monorail trolley, a hand pulling block, a lifting lug, a pull rod, a locking nut, a limiting rod, a top cover and a side door.
Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
The tool for disassembling and assembling the oil groove cover of the upper guide bearing of the hydraulic generator is shown in fig. 1 and 2, is installed above a top cover 9 of a vertical hydraulic generator, comprises a cross beam 1 transversely fixed above the top cover 9, wherein the cross beam 1 is formed by welding I-steel and steel plates, and two ends of the cross beam 1 are respectively provided with vertical through holes.
The sliding rail 2 is hoisted below the beam 1, the upper planes at the two ends of the sliding rail 2 are respectively welded and fixed with a pull rod 6 with threads at the upper ends, the pull rod 6 penetrates out of the vertical through holes at the two ends of the beam 1, and the upper ends of the pull rod 6 are fixed with the beam 1 through locking nuts 7.
A monorail trolley 3 capable of transversely moving along the sliding rail 2 is arranged on the sliding rail 2 in a rolling manner, a chain block 4 is hung at the lower end of the monorail trolley 3, and a lifting lug 5 is sleeved on a lower lifting hook of the chain block 4.
And the two ends of the limiting rod 8 respectively block the wheels of the monorail trolley 3 and control the monorail trolley 3 to move out of the sliding rail 2 when the monorail trolley 3 moves to the position of the limiting rod 8 through the horizontal through holes by penetrating through the horizontal through holes, and the horizontal through holes are respectively arranged at the two ends of the sliding rail 2, and the horizontal through holes are respectively arranged at the two ends of the sliding rail 4.
Before the oil groove cover is disassembled and assembled, the cross beam 1 is placed above the top cover 9, the sliding rail 2 penetrates through two side doors 10 adjacent to the top cover 9 to be parallel to the cross beam 1, the pull rods 1 at two ends of the sliding rail 2 penetrate through vertical through holes in the cross beam 1 to be fixedly connected with the locking nuts 7 through threads, and at the moment, the sliding rail 2 is horizontally fixed above the oil groove cover.
Then the lifting lug 5 is sleeved on the lower lifting hook of the chain block 4, the chain block 4 is hung on the monorail trolley 3, the monorail trolley 3 is arranged on the sliding rail 4, and finally the limiting rod 8 penetrates through the horizontal through holes at the two ends of the sliding rail 4 and is fixed by the limiting nuts. When the oil tank cover is detached, the lifting lug 5 is screwed into the lifting screw hole of the oil tank cover, the oil tank cover is lifted by the chain block 4, the monorail trolley 3 is pushed to move on the sliding rail 2, and the oil tank cover is moved to a specified position. The disassembling tool is convenient to operate, the danger of collision caused by narrow space and heavy oil groove cover in the manual carrying process can be avoided, and the operation safety and the disassembling efficiency of the oil groove cover are improved.
With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
