Technical Field

[0001] The present invention relates to the technical field of metal structures in water conservancy and hydropower projects, and particularly relates to a wire rope tooth type guiding device for an open-top arc gate and its installation structure. Background Art

[0002] In water conservancy and hydropower projects, the common hoisting equipment for open-top arc gates is a fixed winch type hoisting machine. The fixed winch type hoisting machine is connected to the gate lifting lug through a wire rope. The lifting lug is generally arranged on the panel side at the position of the lower main beam of the gate. During the hoisting process of the gate, it is necessary to ensure that the wire rope is tangent to the gate panel, that is, there are requirements for the relative spatial position of the hoisting machine and the gate layout.

[0003] Through the investigation of the actual operation of existing reservoirs in China, due to historical reasons, the actual construction position of the hoisting machine room for the arc gates of the spillways of some large reservoirs does not conform to the original design, resulting in the hoisting machine room being biased towards the downstream side. Consequently, the hoisting machine is arranged towards the downstream side, causing the problem of the top of the arc gate cutting the wire rope, threatening the safe operation of the dam and affecting the normal operation of the reservoir. It is urgent to propose and solve this problem. Summary of the Invention

[0005] To achieve the above purpose, a wire rope tooth type guiding device for an open-top arc gate designed by the present invention includes a base. The base includes a bottom plate. Two parallel support plates perpendicular to the bottom plate are installed on the bottom plate. The two support plates are provided with holes at the same position. Both ends of a wheel shaft are respectively located in the holes of the support plates. At least three guiding steel plates are evenly welded on the wheel shaft. The length direction of the guiding steel plates is parallel to the length direction of the wheel shaft, and the extension line of the short side of the guiding steel plate points to the center of the cross-section of the wheel shaft. The outer surface of each guiding steel plate is concave towards the inside to form a groove with a curvature, and the contact surface between the groove and the side surface of the guiding steel plate is arc-shaped. The wire rope is located in the groove.

[0006] Preferably, a reinforcing rib is connected between the support plate and the bottom plate.

[0010] Preferably, the diameter of the hole is 2-3 mm larger than the diameter of the axle.

[0011] An installation structure of the exposed-top arc gate steel wire rope tooth-type guiding device of the present invention includes a pier, an arc gate and a hoist. A plurality of the exposed-top arc gate steel wire rope tooth-type guiding devices are installed on the outer side of the gate panel of the arc gate. The steel wire rope is connected to the side of the gate panel at the lower main beam position of the arc gate and is connected to the hoist after passing through the exposed-top arc gate steel wire rope tooth-type guiding device.

[0012] Preferably, the exposed-top arc gate steel wire rope tooth-type guiding devices are evenly distributed on the gate panel, and the number is at least three. The exposed-top arc gate steel wire rope tooth-type guiding devices on both sides are located at both ends of the gate panel.
