Description

Technical Field

[0001] This utility model relates to the technical field of arc gate installation in hydropower projects, specifically to an arc gate hinge shaft installation device. Background Technology

[0002] In hydropower projects, the installation of the hinge support for the arc gate through the shaft is usually accomplished by welding auxiliary tools onto the equipment. However, the on-site installation and disassembly of these tools involves a large amount of work and can easily damage the equipment itself.

[0003] To avoid equipment damage, some systems first install fixed hinge seats, connect the movable hinge to part of the support arm to form a whole, and then realize the through-shaft between the movable hinge and the fixed hinge in the hoisting state. However, the hinge shaft of large arc gates is heavy and over 800mm in length, making positioning difficult. The installation site space is also small, and there is no stable force point when the hinge shaft is installed and pushed in. Moreover, the traditional hammering method is very easy to damage the bearing shell, is inefficient, and makes it difficult to complete the installation of the hinge shaft smoothly. Therefore, this utility model provides an arc gate hinge shaft installation device. Utility Model Content

[0004] To address the issues of lacking a stable point of leverage during hinge shaft installation and the inherent problems of traditional hammering methods that easily damage the bearing shell, resulting in low efficiency and difficulty in successfully completing hinge shaft installation, this utility model provides an arc gate hinge shaft installation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A hydraulic telescopic component, one end of which is hinged to the jacking backrest, and the other end of which faces the outer end of the arc gate hinge shaft.

[0010] The jacking bracket and jacking backing are used together to provide a jacking point for the installation of the hinge shaft. When the hydraulic telescopic component is working, it can provide a stable pushing force to the end of the hinge shaft. Compared with the traditional hammering method, it is more stable and efficient, and will not damage the bearing, so that the hinge shaft can be installed smoothly.

[0011] As a further description of the above technical solution:

[0012] The jacking support includes: two symmetrically distributed long frames, with multiple short frames fixedly connected between the two long frames, and one end of each of the two long frames retracting inward and fixedly connected with a fastener.

[0015] As a further description of the above technical solution:

[0016] The jacking back support includes: an I-beam, with a lug fixedly connected to the front side of the I-beam and a limiting block fixedly connected to the rear side of the I-beam.

[0017] As a further description of the above technical solution:

[0034] Please refer to the attached document. Figures 1-5 This application illustrates an arc gate hinge shaft installation device provided in an embodiment of the present application, used for shaft insertion operations when the hinge seat, hinge chain, and hinge shaft of a large arc gate in hydropower projects are installed separately. Specifically, it includes: a pair of jacking brackets 1, a jacking backing piece 2, and a hydraulic telescopic piece 3.

[0035] One end of the jacking bracket 1 is provided with a fastener 103 that connects to the hinge end. The fastener 103 is detachably installed at the hinge end (for example, by bolting it to the stop bolt hole at the hinge end). The jacking backrest 2 is placed horizontally at the jacking bracket 1, and one end of the hydraulic telescopic member 3 is hinged to the jacking backrest 2. The other end of the hydraulic telescopic member 3 faces the outer end of the arch hinge shaft. The jacking bracket 1 and the jacking backrest 2 are used together to provide a force point for the jacking of the hinge shaft. When the hydraulic telescopic member 3 is working, it can provide a stable pushing force to the end of the hinge shaft. Compared with the traditional hammering method, it is stable and efficient, and will not damage the bearing, so that the hinge shaft can be installed smoothly.

[0036] In one embodiment, the jacking support 1 includes two symmetrically distributed long frames 101, a plurality of short frames 102 fixedly connected between the two long frames 101, and one end of the two long frames 101 retracts inward and is fixedly connected to a fastener 103.

[0037] Each of the short frames 102 can serve as a support for the jacking backrest 2. In actual use, the position of the jacking backrest 2 can be adjusted according to the advancement process of the hinge shaft. Both the short frames 102 and the long frames 101 are made of solid steel pipe structure, which has sufficient tensile strength.

[0038] In one embodiment, the fastener 103 includes: a main body 103a, which is connected to two symmetrically distributed long frames 101 by rivets, and a connecting ear 103c is fixedly connected to the first end of the main body 103a so that the connecting ear 103c can be fixedly connected to the anchor bolt hole at the end of the hinge by bolts. An H-shaped connecting part 103b is fixedly connected to the second end of the main body 103a. The two long frames 101 are respectively arranged at the two openings of the H-shaped connecting part 103b, which can further improve the stability of the connection between the fastener 103 and the long frame 101.

[0039] In one embodiment, the jacking backrest 2 includes: an I-beam 201, with a lug 203 fixedly connected to the front side of the I-beam 201 for connecting the hydraulic telescopic member 3, and a limiting block 202 fixedly connected to the rear side of the I-beam 201. The limiting block 202 protrudes beyond the short frame 102, thus preventing the I-beam 201 from sliding during use and ensuring stability and safety during use.

[0040] In one embodiment, the hydraulic telescopic component 3 includes: a hydraulic cylinder 301, a block plate 302 fixedly connected to the tail of the hydraulic cylinder 301, a sliding hole 303 provided on the block plate 302, and the block plate 302 connected to the lug 203 through a shaft.

[0041] In actual use, the block plate 302 can slide relative to the shaft on the lug 203, so that the end of the block plate 302 directly abuts against the I-beam 201.

[0042] In one embodiment, in order to facilitate the user's operation of the hydraulic cylinder 301, an operating lever 304 is fixedly connected to the side of the hydraulic cylinder 301.

[0043] In one embodiment, in order to protect the end of the hinge shaft, a pad 305 is fixedly connected to the telescopic end of the hydraulic cylinder 301. The pad 305 can be a rubber pad or a copper pad.

[0044] Two jacking supports 1 are used as a group, which are welded from round steel with a diameter of 20mm and a length of about 1300mm (adjusted according to the length of the hinge shaft). Short supports 102 are set at intervals of 250mm.

[0045] (1) When using it, first fix the hinge seat and the bracket bolt, and then pour the concrete.

[0046] (2) Connect the jacking brackets 1 used in pairs symmetrically in the hinge seat stop bolts, and set two symmetrically across the axis center line.

[0047] (3) Insert the hinge shaft into the hinge flange using a hoisting device, and fix the shaft in place using a mounting bracket and slings.

[0048] (4) Insert the push-in backing piece 2 into the support gap of the push-in bracket at a suitable distance.

[0049] (5) Place the hydraulic telescopic component 3 in the gap between the jacking backing component 2 and the shaft end face, and use the hydraulic telescopic component 3 to slowly push the shaft into the hinge.

[0050] (6) When the stroke of the hydraulic telescopic component 3 is insufficient, retract the hydraulic telescopic component 3 to reset the stroke, then move the jacking backing component 2 towards the shaft by one support space, and then use the hydraulic telescopic component 3 to jack through the shaft. Repeat this process until the hinge shaft is installed in place.

[0051] (7) During use, tools such as the jacking backrest 2 and hydraulic telescopic component 3 need to be secured with safety ropes to prevent them from falling.
