Description

Technical Field

[0001] This invention belongs to the field of water conservancy and hydropower engineering technology, specifically relating to an H-shaped steel track hoisting device for an arched top arch. Background Technology

[0002] It is common for hydropower stations to have steel beams and tracks. Suspended lifting equipment needs to be installed on the top arch to cover the area for equipment hoisting, maintenance and replacement. For planar top arches, steel tracks are usually welded to embedded parts or connected by embedded bolts. For arched top arches, track connectors are added between the embedded parts and the steel. However, due to the limited hoisting space, conventional hoisting methods cannot directly hoist the track accessories into place. Scaffolding needs to be erected and auxiliary measures are required to hoist them into place. Since the track distance of the hoisting equipment is long, the scaffolding needs to be erected in sections multiple times. A large number of scaffolding pipes are needed to complete the erection at one time, which occupies a lot of turnover materials and site space, resulting in long time, high cost, low efficiency and high construction safety risks. Summary of the Invention

[0003] The technical problem to be solved by this invention is that, in the construction of the steel track hoisting of the arc-shaped top arch of a hydropower station, the traditional method requires the use of scaffolding and other auxiliary devices to hoist the track into place, which is inefficient and poses safety hazards.

[0004] To solve the above-mentioned technical problems, the present invention provides an H-shaped steel rail hoisting device for an arched dome, comprising: an embedded part, a connector, a clamping structure, a supporting structure, a hand-operated hoist, and shackles. The upper part of the embedded part is fixedly connected to the arch beam, and the lower part of the embedded part is fixedly connected to the port of the connector. The connector is a U-shaped frame structure formed by combining three steel plates. Two clamping structures are symmetrically arranged and clamped into the connector. One end of each of the two hand-operated hoists is connected to the clamping structure through two shackles, and the other end of each hand-operated hoist is connected to the supporting structure through two more shackles. An H-shaped steel rail is fixed to the top of the supporting structure.

[0005] Furthermore, the clamping structure includes: a steel plate, an ear plate A, a nut, a channel steel, a bolt, and a guide plate. The ear plate A is connected to the lower side of one side of the steel plate, and the nut is provided on the upper side of the other side of the steel plate. The channel steel and the guide plate are provided below the other side. The groove of the channel steel faces the ear plate A. The guide plate is located on the back side of the groove of the channel steel. A U-shaped groove is opened on the steel plate. The channel steel and the guide plate are located on the left and right sides of the U-shaped groove, respectively. The U-shaped groove is inserted into one side end of the connector. The ear plate A is engaged with the shackle. One end of the bolt passes through the nut, and the other end of the bolt hooks onto the edge of the upright plate of the connector. The bolt is similar to a J-shape.

[0006] Furthermore, the support structure includes: an I-beam, an ear plate B, a reinforcing channel steel A, a reinforcing channel steel B, a steel column, a track pressure plate, and limiting bolts. The groove and the back of the groove of the reinforcing channel steel A are respectively vertically fixedly connected to one end of the two I-beams to form a cross-shaped base. A steel column is provided on the top of the I-beam, and an ear plate B is provided on the top of the end of the I-beam. The front and back of the steel column are respectively fixedly connected to the two reinforcing channel steels B. The connection between the steel column and the reinforcing channel steel B is fixedly connected to the track pressure plate by limiting bolts. One side of the track pressure plate is connected to an H-beam track.

[0007] The beneficial effects of this invention are as follows: The H-shaped steel track hoisting device for arched roofs of this invention connects the connector, clamping structure, hand-operated hoist, and support structure in sequence, and fixes the connector to the embedded parts fixed to the arch. This allows the hoisting device to perform hoisting work without the need for scaffolding. Simultaneously, the clamping structure directly engages with the connector via a U-shaped groove, and tightening the bolts effectively prevents the clamping structure from disengaging during hoisting, making the connection simple and reliable. Furthermore, the support body and the H-shaped steel track are securely fixed by a track pressure plate, ensuring reliable connection, easy disassembly, and safe hoisting operations. In summary, the H-shaped steel track hoisting device for arched roofs of this invention has a stable structure, is easy to operate, and can significantly improve the hoisting efficiency of H-shaped steel tracks in confined spaces.
