[0002] The hoist chamber is an important component structure of the dam. In the prior art, there are relevant patents that disclose the structure of the hoist chamber. For example, the patent with the announcement number CN215482772U discloses a hoist chamber structure, which is convenient for operators to open and close the gate while ensuring the seismic performance of the sluice. For another example, the patent with the announcement number CN215518647U discloses a steel dam gate with a hoist chamber below. By installing the hoist chamber on the bottom plate, the use of the middle pier can be eliminated, thereby increasing the flow and flood discharge capacity of the river channel, and at the same time eliminating the landscape impact caused by the arrangement of the gate piers, so that the river channel can form a continuous water surface, and improve the river channel landscape effect.
[0003] However, no anti-seismic and shock-absorbing measures are adopted inside the gate hoist room in the prior art. Since it is located at a higher position on the dam body, under high earthquake intensity, the amplification effect causes a large dynamic response of the gate hoist room structure, and conventional structural design is difficult to meet the requirements of crack resistance and stability. Utility Model Content

[0006] Preferably, the first damper and the second damper are both hydraulic dampers; the hydraulic damper comprises an oil storage cylinder and a piston arranged inside the oil storage cylinder, and damping oil is arranged in the oil storage cylinder.
[0007] Preferably, each column is a segmented structure, and the joint between the two sections of the column is located below the crossbeam; there are two first dampers inside each column, which are respectively located on the upper and lower sides of the joint of the column, and the two first dampers are vertically arranged with their axes collinear, and the pistons of the two first dampers are connected by the same vertical piston rod.
[0008] Preferably, the second damper is arranged horizontally, a transverse piston rod is connected to the piston of the second damper, and a horizontal connecting rod is connected to the end of the oil storage cylinder of the second damper; one end of the transverse piston rod away from the second damper is connected to the vertical piston rod inside one of the columns; one end of the horizontal connecting rod away from the second damper is connected to the vertical piston rod inside the other column.
[0009] Preferably, an anchor rod is provided at the end of the oil storage cylinder of the first damper, and the anchor rod is anchored in the column.
[0010] Preferably, a damping control valve is provided on the oil storage cylinder.
[0011] Preferably, a stroke marking line is provided on the cylinder wall of the oil storage cylinder.
[0012] Preferably, each column is a segmented structure, a concave groove is provided on the docking surface of one segment of the column, and a convex block is provided on the docking surface of the other segment of the column; when the two segments of the column are docked, the convex block is snapped into the concave groove.
[0013] Due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows:
[0014] (1) Compared with the existing hoist room structure, by arranging dampers inside the columns and between two adjacent columns, part of the seismic energy can be absorbed and the seismic resistance can be improved. This structure has the advantage of good seismic energy reduction effect.

[0025] As shown in the attached drawings, a dam gate hoist chamber structure with a damper disposed inside, the hoist chamber 1 is located above the working gate 13, and the hoist chamber 1 includes columns 2, beams 3 and floor slabs 4; four columns 2 are vertically arranged, and the four columns 2 are distributed in a rectangular shape; a beam 3 is cast between two adjacent columns 2, and the four beams 3 are at the same height, and the floor slab 4 is cast on the beam 3; a first damper 5 is disposed inside each column 2, and a second damper 6 is disposed between two adjacent columns 2. Further, the first damper 5 and the second damper 6 are both hydraulic dampers; the hydraulic damper includes an oil storage cylinder 7, and a piston 8 disposed inside the oil storage cylinder 7, and damping oil is disposed inside the oil storage cylinder 7.
[0026] Combination Figure 3 As shown, each column 2 is a segmented structure, and the joint between the two sections of the column is located below the crossbeam 3; there are two first dampers 5 inside each column 2, which are respectively located on the upper and lower sides of the joint of the column 2, and the two first dampers 5 are vertically arranged with their axes collinear; the pistons 8 of the two first dampers 5 are connected by the same vertical piston rod 9.
[0027] Combination Figure 3 As shown, the second damper 6 is arranged horizontally, and a transverse piston rod 10 is connected to the piston 8 of the second damper 6, and a horizontal connecting rod 11 is connected to the end of the oil storage cylinder 7 of the second damper 6; the end of the transverse piston rod 10 away from the second damper 6 is connected to the vertical piston rod 9 inside one of the columns 2; the end of the horizontal connecting rod 11 away from the second damper 6 is connected to the vertical piston rod 9 inside another column 2. Since the two first dampers 5 in each column 2 are arranged vertically, and the second damper 6 between two adjacent columns 2 is arranged horizontally, the energy of earthquakes in different directions horizontally and vertically can be effectively reduced by both horizontal and vertical settings. When an earthquake occurs, part of the earthquake energy is absorbed by the damping oil, the displacement of the column 2 caused by the earthquake is reduced, and the energy is reduced at the bottom to reduce the impact on the upper structure.
[0028] Combination Figure 3 As shown, an anchor rod 12 is provided at the end of the oil storage cylinder 7 of the first damper 5 , and the anchor rod 12 is anchored in the column 2 to enhance the fastening of the oil storage cylinder 7 .
[0029] A damping control valve (not shown in the figure) is arranged on the oil storage cylinder 7 . The purpose of arranging the damping control valve is to adjust the damping strength of the damping oil inside the oil storage cylinder 7 .
[0030] In this embodiment, a stroke marking line (not shown in the figure) is provided on the cylinder wall of the oil storage cylinder 7. Specifically, a transparent observation window is provided on the cylinder wall of the oil storage cylinder 7 for observing the movement of the piston 8 inside the oil storage cylinder 7. The stroke marking line is provided on the cylinder wall of the oil storage cylinder 7 to indicate the displacement of the piston 8.

Specifically, the concave grooves 2a on the two adjacent columns 2 are in opposite directions, which can prevent the column from being displaced or slipping to one side.
[0032] During use, the first damper 5 and the second damper 6 need to be checked regularly, and if the damper structure is damaged or the damping oil is leaking, they need to be repaired or replaced in time.
