Description

Technical Field

[0001] This utility model relates to the field of gate lifting technology, and in particular to a temporary lifting replacement device for gate hoists in small space cantilever operation conditions. Background Technology

[0002] Traditional gate lifting relies on general-purpose hoists, which have high requirements for installation sites, occupy a large area, have long installation time, and are costly. When temporarily lifting underwater gates during the construction phase of some projects, the space is small, and the gates are suspended above the water surface, making it difficult to temporarily open and close them with the hoist. Summary of the Invention

[0003] The present invention aims to address the shortcomings of the prior art by providing a temporary lifting alternative for gate hoists in small-space cantilever operation conditions.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A temporary lifting alternative device for gate hoists in small-space cantilever operation includes a through-hole jack, a precision-rolled threaded steel bar, a steel wire rope, a cantilever distribution beam, and a transverse distribution beam. The tail ends of the two cantilever distribution beams are inserted into the top of the dam. The front support of the cantilever distribution beam is fixed on the embedded part A on the edge of the dam. A transverse distribution beam is fixed between the two cantilever distribution beams corresponding to the gate position. The jack support is fastened to the transverse distribution beam by anchors. The through-hole jack is fixed on the jack support. The precision-rolled threaded steel bar is connected to the telescopic end at the center of the through-hole jack. The precision-rolled threaded steel bar passes downward through the jack support and the transverse distribution beam and is connected to the steel wire rope through a connector. The bottom of the steel wire rope is connected to the gate.

[0006] An anchor plate is provided between the jack support and the transverse distribution beam. The anchor passes through the jack support and the anchor plate in sequence and is then fastened to the transverse distribution beam.

[0007] The cantilever distribution beam is a double beam structure. The two cantilever distribution beams are set in parallel and the spacing is adapted to the width of the gate. The transverse distribution beam is erected vertically between the two cantilever distribution beams and forms a cross-shaped support structure.

[0008] The tail end of the cantilever distribution beam is equipped with an anchor beam, which is connected to the embedded part B pre-embedded in the top of the dam via a corbel.

[0009] The embedded part B includes a steel plate B, a reinforcing bar B, and a cross-shaped steel plate. Six reinforcing bars B are evenly distributed in two rows on one side of the steel plate B, and the other side is connected to one end of the cross-shaped steel plate. The bracket is formed by butt welding two channel steel slots and is fitted onto the cross-shaped steel plate. The reinforcing bars B are embedded in the concrete at the top of the dam.

[0010] The embedded part A includes a steel plate A and a reinforcing bar A. Four reinforcing bars A are evenly distributed on one side of the steel plate A. The reinforcing bars A are embedded in the concrete along the edge of the dam.

[0011] The connector includes an upper connecting structure and a lower connecting structure. The upper connecting structure includes two grooved plates with opposite openings, a groove connecting plate, and a pad. The groove connecting plate is welded to the top two sides of the two grooved plates with opposite openings. A gap is left between the two grooved plates with opposite openings. A pad is placed at the middle gap at the bottom of the two grooved plates with opposite openings. The lower connecting structure includes a grid-shaped cross plate and a wire rope shaft connecting plate with a round hole. Two parallel plates in the grid-shaped cross plate extend upward into the gap between the two grooved plates and downward to the sides of the two wire rope shaft connecting plates, and connect with the wire rope shaft connecting plates. A wire rope guide shaft is placed in the round hole of the two wire rope shaft connecting plates. The wire rope guide shaft is used to connect with the wire rope.

[0012] An operating platform is erected on the cantilevered distribution beam, and railings are installed around the four sides of the operating platform.

[0013] The beneficial effects of this utility model are: the installation area occupied by this utility model is reduced by 80%, the amount of steel structure used is reduced by 60%, it breaks through the dependence of traditional hoists on fixed bases and large installation sites, and the cantilever structure realizes the precise lifting of the gate in mid-air.
