Description

Technical Field

[0001] The utility model belongs to the technical field of gate slot protection, and relates to a protection device for the overhaul gate slot at the top of a dam Background Art

[0002] Generally, the top of the overhaul gate slot at the top of the dam is protected by a steel grille. Due to the large size of the gate slot orifice, considering safety, the steel grille at the top of the gate slot is made relatively strong, heavy and difficult to be transported manually. It is mainly covered or uncovered by lifting with a gantry crane on the dam top. There are mainly the following problems with using the gantry crane for transportation. First, it occupies the gantry crane resources. Second, the lifting by the gantry crane belongs to the operation of special equipment with high safety risks. Third, a special area for placing the steel grille needs to be set on the dam top, which affects the overall layout and the beauty of the dam top. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a protection device for the overhaul gate slot at the top of a dam, in which the gate slot cover plate is arranged in the receiving groove on the side wall of the dam gate slot, and the horizontal telescopic mechanism and the lifting mechanism are used to realize the horizontal pushing and lifting of the gate slot cover plate, without using large equipment such as gantry cranes, and without reserving a parking position for the gate slot cover plate, which is simple, convenient, safe and reliable.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a protection device for the overhaul gate slot at the top of a dam, which includes a gate slot cover plate, a horizontal telescopic mechanism and a lifting mechanism; the gate slot cover plate is clamped with the horizontal telescopic mechanism; two horizontal telescopic mechanisms are fixed in the receiving grooves on both side walls of the gate slot, and two lifting mechanisms are fixed on the steps on the other two sides of the gate slot; the horizontal telescopic mechanism drives the gate slot cover plate to move horizontally onto the lifting mechanism, and the lifting mechanism drives the gate slot cover plate to move up and down.

[0005] The gate slot cover plate is a horizontal plate, and a plurality of rollers are arranged on the lower side.

[0006] A T-shaped groove is arranged on the lower side surface of the gate slot cover plate.

[0007] The horizontal telescopic mechanism is an electric push rod, and the fixed end of the electric push rod is fixed to the inner wall of the receiving groove.

[0008] A T-shaped block is arranged at the telescopic end of the horizontal telescopic mechanism.

[0009] The lifting mechanism is an electric push rod, the fixed end of the electric push rod is fixed to the gate slot step; the telescopic end of the electric push rod is connected to a supporting plate.

[0010] The main beneficial effects of the utility model are as follows:

[0011] The gate slot cover plate is driven by a telescopic mechanism to move horizontally so that the gate slot cover plate is located on the supporting plate of the lifting mechanism. The lifting mechanism drives the slot cover plate to rise to be flush with the gate slot orifice. There is no need to use large-scale equipment such as gantry cranes, and there is no need to reserve a parking area for the gate slot cover plate, which is simple, convenient, safe and reliable.

[0012] When the gate slot is not closed, the gate slot cover plate is located in the receiving groove, making full use of the space of the receiving groove. The gate slot cover plate cannot be seen from the upper part of the gate slot, which is beautiful; and it is not affected during the lifting and lowering process of the gate slot gate, and there is no need to set up a stacking area for the gate slot cover plate separately.

[0018] As Figures 1 to 3 shown in, a maintenance gate slot protection device for the top of a dam includes a gate slot cover plate 1, a horizontal telescopic mechanism 2 and a lifting mechanism 3; the gate slot cover plate 1 is clamped with the horizontal telescopic mechanism 2; two horizontal telescopic mechanisms 2 are fixed in the receiving grooves 4 on both side walls of the gate slot, and two lifting mechanisms 3 are fixed on the steps on the other two sides of the gate slot; the horizontal telescopic mechanism 2 drives the gate slot cover plate 1 to move horizontally onto the lifting mechanism 3, and the lifting mechanism 3 drives the gate slot cover plate 1 to move up and down. The gate slot cover plate 1 is driven by the telescopic mechanism 2 to move horizontally so that the gate slot cover plate 1 is located on the supporting plate 31 of the lifting mechanism 3. The lifting mechanism 3 drives the slot cover plate 1 to rise to be flush with the gate slot orifice. There is no need to use large-scale equipment such as gantry cranes, and there is no need to reserve a parking area for the gate slot cover plate, which is simple, convenient, safe and reliable.

[0019] In a preferred solution, the gate slot cover plate 1 is a horizontal plate, and a plurality of rollers 11 are arranged on the lower side. During use, the rollers 11 at the lower part of the gate slot cover plate 1 reduce the resistance, making the gate slot cover plate 1 more stable under the push and pull of the horizontal telescopic mechanism 2.

[0020] In a preferred solution, a T-shaped groove 12 is arranged on the lower side surface of the gate slot cover plate 1. During use, when the gate slot cover plate 1 is in the receiving groove 4, the T-shaped groove 12 forms a clamping connection with the T-shaped block 21.

[0021] In a preferred solution, the horizontal telescopic mechanism 2 is an electric push rod, and the fixed end of the electric push rod is fixed to the inner wall of the receiving groove 4. During installation, the fixed end of the horizontal telescopic mechanism 2 is fixed to the side wall of the receiving groove 4, which is not visible at the top of the door groove, saving space and being aesthetically pleasing.

[0022] In a preferred solution, a T-shaped block 21 is provided at the telescopic end of the horizontal telescopic mechanism 2. During use, when the door groove cover plate 1 is rising, the T-shaped block 21 gradually disengages from the T-shaped groove 12, enabling the door groove cover plate 1 to rise smoothly; conversely, when the door groove cover plate 1 is descending, the T-shaped block 21 gradually engages with the T-shaped groove 12, connecting the door groove cover plate 1 and the horizontal telescopic mechanism 2 into a whole, and retracting the door groove cover plate 1 into the receiving groove 4 under the drive of the horizontal telescopic mechanism 2.

[0023] In a preferred solution, the jacking mechanism 3 is an electric push rod, and the fixed end of the electric push rod is fixed to the door groove step; the telescopic end of the electric push rod is connected to the supporting plate 31. During installation, the fixed end of the jacking mechanism 3 is installed on the concave door groove step, which does not affect the lifting of the gate in the door groove; during use, the supporting plate 31 is used to support the door groove cover plate 1.

[0024] The above embodiments are only the preferred technical solutions of the present utility model and should not be regarded as limitations on the present utility model. The embodiments and the features in the embodiments in this application can be arbitrarily combined with each other without conflict. The protection scope of the present utility model should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present utility model.
