Description

Technical Field

[0001] The invention relates to the technical field of metal structures of water conservancy and hydropower engineering, and in particular to a double-trolley arrangement structure of a multi-hole water inlet of a reservoir. Background Art

[0002] In water conservancy and hydropower projects, trash racks and water intake lapped beam gates are usually installed in sequence at the entrance of the water intake tunnel along the water flow direction. The trash rack is a flat upright trash rack, which is arranged in sections, and the water intake gate is a flat lapped beam gate, which is arranged in sections. The trash rack and the water intake gate can be operated by a gantry crane or a trolley through mechanical beam grabbing.

[0003] If the water inlet hole is multi-hole, the gantry crane needs to use a two-way gantry crane to control the inspection gate and the trash rack at the same time, but the two-way gantry crane has a large investment, or the trash rack and the stoplog gate are operated in the conventional way with one trolley each. Since the two trolleys are large in size and there is at least 60 cm of inspection space between the two trolleys, the arrangement of the two trolleys takes up a large space along the water flow, so the concrete engineering volume of the water intake tower of the water intake tunnel is large.

[0004] Therefore, it is necessary to propose a solution that takes up less space, reduces the volume of concrete, and requires less investment, with respect to the layout and operation of the trash rack and water intake gate at the inlet of the existing reservoir dam water intake tunnel. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies of the above-mentioned technology and provide a double-trolley arrangement structure for a reservoir multi-hole water inlet, which has a compact layout, saves plane space, reduces the structural size of the water intake tower, thereby reducing the volume of concrete and saving investment.

[0006] To achieve the above-mentioned purpose, the present invention is a double-trolley arrangement structure for a multi-porous water inlet of a reservoir, comprising a trash rack and a water intake folded beam gate arranged in sequence along the water flow direction from the water intake tunnel inlet, the trash rack being arranged in sections, the trash rack being opened and closed by a trash rack hoist, the water intake folded beam gate being arranged in sections, the water intake folded beam gate being opened and closed by a water intake folded beam gate hoist, and also comprising a hoist track group arranged above the trash rack and the water intake folded beam gate, the hoist track group comprising a first track, a second track and a third track which are parallel to each other and arranged in a direction perpendicular to the water flow direction, a first mobile trolley and a second mobile trolley being arranged on the hoist track group, the first mobile trolley being moved by the first track and the second track, the second mobile trolley being moved by the second track and the third track, the trash rack hoist being installed on the first mobile trolley, and the water intake folded beam gate hoist being installed on the second mobile trolley.

[0007] Preferably, the opening and closing of the trash rack is operated by the first mobile trolley through a hydraulic grab beam.

[0008] Preferably, the water intake stoplog gate is opened and closed by the second mobile trolley through hydraulic beam grabbing operation.

[0009] Preferably, the height of the trash rack is higher than the highest characteristic water level.

[0010] Preferably, the height of the stoplog gate is determined according to the water intake level difference.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. Compact layout, saving plane space, reducing the structural size of the water intake tower, thereby reducing the volume of concrete and saving investment;

[0013] 2. It can be used to replace the traditional layout of large trolley space occupation, large water intake tower size or large gantry crane investment, especially suitable for the layout of porous trash racks and water intake stoplog gate hoists and hoists. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the double trolley arrangement structure of the multi-hole water inlet of the reservoir of the present invention;

[0015] Figure 2 This is a schematic diagram of the layout of the conventional gate hoist layer.

[0016] The components in the figure are numbered as follows:

[0017] A first track 1 , a second track 2 , a third track 3 , a first movable trolley 4 , and a second movable trolley 5 . DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, the present invention provides a double trolley arrangement structure for a multi-hole water inlet of a reservoir, comprising a trash rack and a water intake lapped beam gate arranged in sequence along the water flow direction from the water intake tunnel inlet, the trash rack being arranged in sections, the trash rack being opened and closed by a trash rack hoist, the water intake lapped beam gate being arranged in sections, the water intake lapped beam gate being opened and closed by a water intake lapped beam gate hoist, and also comprising a hoist track group arranged above the trash rack and the water intake lapped beam gate, the hoist track group comprising a first track 1, a second track 2 and a third track 3 which are parallel to each other and arranged in a direction perpendicular to the water flow direction, a first movable trolley 4 and a second movable trolley 5 are arranged on the hoist track group, the first movable trolley 4 moves via the first track 1 and the second track 2, the second movable trolley 5 moves via the second track 2 and the third track 3, the trash rack hoist is installed on the first movable trolley 4, and the water intake lapped beam gate hoist is installed on the second movable trolley 5.

[0020] When the embodiment is used, the height of the trash rack is higher than the highest characteristic water level, and the opening and closing of the trash rack is operated by the first mobile trolley 4 through the hydraulic grab beam. The height of the stoplog gate is determined according to the water level difference of the water intake, and the opening and closing of the water intake stoplog gate is operated by the second mobile trolley 5 through the hydraulic grab beam.

[0021] like Figure 2 As shown in the figure, the layout of the gate hoist on the conventional gate hoist layer is as follows. The two trolleys run on two tracks respectively. According to the design specifications of steel gates for water conservancy and hydropower projects, the net distance between the gate hoist and the wall of the machine room should not be less than 800mm, and the maintenance space between the two gate hoists should not be less than 600mm, that is, there is a certain spacing requirement between the two middle tracks. If the gate hoist itself is larger in size, then the structural size of the water intake tower along the water flow direction will increase accordingly.

[0022] In this embodiment, by setting three tracks, the first mobile trolley 4 and the second mobile trolley 5 share the third track 3, which shortens the distance between the gate hoists, reduces the maintenance space between the gate hoists, and correspondingly reduces the size of the hydraulic structure and the project investment.

[0023] The double trolley arrangement structure of the porous water inlet of the reservoir of the present invention has a compact arrangement, saves plane space, reduces the structural size of the water intake tower, thereby reducing the volume of concrete and saving investment; it can be used to replace the traditional arrangement method in which the trolley occupies a large space, the water intake tower is large in size or the gantry machine investment is large, and is particularly suitable for the arrangement method of the multi-porous trash rack and the water intake stacked beam gate hoist layer hoist.
