Description

Technical Field

[0001] This utility model relates to the technical field of maintenance equipment for drift barriers in water conservancy and hydropower projects, and in particular to a trapezoidal load-bearing steel support for the maintenance of box-type steel drift barrier floats. Background Technology

[0002] Float barriers, typically located in front of hydroelectric power stations, are flexible, integral structures composed of a series of individual floats connected by connecting plates, rods, pins, and steel cables. They float on the water surface using the buoyancy of these floats. A grate is usually installed at the bottom of the floats to intercept floating objects within a certain depth range in the water flow, preventing them from drifting towards the dam and ensuring the normal operation of the hydroelectric power station's generating units. The floats are steel components that provide buoyancy to the float barrier; they are generally box-shaped or cylindrical structures.

[0003] To prevent the float from rusting, leaking, or sinking, which would affect the effectiveness of the float barrier, the float needs to be periodically hoisted ashore for inspection and maintenance. In existing technology, box-shaped steel floats are typically placed sideways on the ground after hoisting, which has the following drawbacks: First, due to the limitations of the bottom grate structure, the float cannot be laid flat on the ground directly after hoisting; it must be manually pulled sideways by workers, which is difficult, poses high safety risks, and is prone to structural damage upon landing due to impacts. Second, direct contact between the float and the ground can easily damage the anti-corrosion paint on the surface. Finally, the direct contact between the side of the box-shaped steel float and the ground restricts maintenance operations. Utility Model Content

[0004] This utility model provides a trapezoidal load-bearing steel bracket for the maintenance of box-type steel drift barrier floats. It aims to solve the problems mentioned above, such as the lack of suitable support equipment when maintaining existing drift barrier floats, the difficulty of operation due to side placement, the high safety risks, the structural damage caused by impacts when the float lands, and the damage to the anti-corrosion paint on the surface of the float due to direct contact with the ground, which restricts maintenance operations.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A trapezoidal load-bearing steel support for the maintenance of a box-shaped steel drift barrier includes a base frame. The top of the base frame is provided with oppositely arranged support brackets, all of which are perpendicular to the base frame and have a pre-reserved gap between them. The top of each support bracket is provided with an anti-slip component. When the box-shaped steel drift barrier is supported on the top of the support bracket, the box-shaped steel drift barrier forms a frictional damping engagement with the top of the support bracket through the anti-slip component, and the hanging grid at the bottom of the box-shaped steel drift barrier passes through the pre-reserved gap between the support brackets.

[0006] Preferably, the receiving bracket is arranged symmetrically about the middle position of the base frame.

[0007] Preferably, the height of the receiving bracket is greater than the height of the hanging grid, and the width of the gap is greater than the width of the hanging grid.

[0008] Preferably, the anti-slip component is an anti-slip rubber pad, which is fixed to the top of the support bracket.

[0009] Preferably, the support bracket is a trapezoidal steel frame structure, which includes a bottom crossbeam as the bottom edge of the trapezoid and a top crossbeam as the top edge of the trapezoid. The side of the top crossbeam closest to the gap is supported by a column and the bottom crossbeam, while the side of the top crossbeam furthest from the gap is supported by a diagonal brace and the bottom crossbeam.

[0010] Preferably, the support bracket is a right trapezoid with the column perpendicular to the bottom crossbeam.

[0011] Preferably, a diagonal brace is provided between the diagonal brace and the column, and the diagonal brace and the column are supported by the diagonal brace.

[0012] Preferably, the oppositely arranged support brackets are arranged on the same bottom crossbeam.

[0013] Preferably, the base frame is a rhomboid steel frame structure, the base frame includes a bottom stabilizing beam that serves as a side of the rhombus, and a bottom crossbeam that serves as one of the diagonals of the rhomboid steel frame and is fixedly fitted to the bottom stabilizing beam.

[0014] Preferably, a steel frame is welded and fixed between the top corner of the base frame and the bottom crossbeam to form another diagonal of the rhomboid steel frame.

[0015] The beneficial effects of this utility model are: 1. The number and arrangement of steel frames can be determined according to the size of the drift barrier and float. The structure is simple, the assembly is convenient, and it meets the maintenance needs of drift barrier and float of different sizes. 2. The gaps between the columns of the steel frame support are reserved for the hanging grid to pass through, so that the float can be suspended on the support, avoiding damage to the float if it is placed directly on the ground, and increasing the maintenance space. 3. The anti-slip components at the top of the support can increase the friction coefficient of the contact surface, reduce the sliding friction between the float and the support, protect the anti-corrosion paint on the surface of the float, and improve the safety and stability of the support.

[0017] The embodiments will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown in the preferred embodiment 1, a trapezoidal load-bearing steel support for the maintenance of a box-shaped steel drift barrier includes a base frame. The top of the base frame is provided with oppositely arranged support brackets, all of which are perpendicular to the base frame and have a gap reserved between them. The top of each support bracket is provided with an anti-slip component. When the box-shaped steel drift barrier 8 is supported on the top of the support bracket, the box-shaped steel drift barrier 8 forms a friction damping engagement with the top of the support bracket through the anti-slip component, and the hanging grid 9 at the bottom of the box-shaped steel drift barrier 8 just passes through the gap reserved between the support brackets.

[0019] In use, at least two load-bearing steel supports should be arranged as a group to ensure the support at both ends of the box-shaped steel drift barrier float 8. The float is then placed on the support brackets of the two load-bearing steel supports, so that the box-shaped steel drift barrier float 8 is suspended off the ground, allowing for maintenance of the float and the hanging grid 9 below. The specific number and spacing can be adjusted according to actual conditions to make it more suitable for box-shaped steel drift barrier floats 8 of various sizes and lengths.

[0020] The supporting brackets are symmetrically arranged about the middle position of the base frame to ensure the stability of the support under stress.

[0021] The height of the receiving bracket is greater than the height of the hanging grid 9, and the width of the gap is greater than the width of the hanging grid 9. This prevents the hanging grid 9 from interfering with the ground or the base frame and ensures the smooth passage of the hanging grid 9.

[0022] The anti-slip component is an anti-slip rubber pad 7, fixed to the top of the receiving bracket. It can be fixed to the top of the receiving bracket by means of concealed fasteners or adhesive bonding, increasing friction and preventing the box-shaped steel drift barrier 8 from sliding during maintenance, thus ensuring the stability and safety of the box-shaped steel drift barrier 8.

[0023] In a preferred embodiment 2, the supporting bracket is a trapezoidal steel frame structure, comprising a bottom crossbeam 3 as the base of the trapezoid and a top crossbeam 2 as the top edge of the trapezoid. The side of the top crossbeam 2 closest to the gap is supported by a column 1 and the bottom crossbeam 3, while the side of the top crossbeam 2 furthest from the gap is supported by a diagonal brace 5. This ensures the stability of the load-bearing structure, forming a floating support that keeps the bottom of the float away from the ground.

[0024] The support frame is a right-angled trapezoid, with column 1 perpendicular to the bottom crossbeam 3. This ensures stability under stress.

[0025] A diagonal brace 6 is provided between the diagonal rod 5 and the column 1, and the diagonal rod 5 and the column 1 are supported by the diagonal brace 6. This ensures the stability of the load.

[0026] The supporting supports are arranged opposite to each other on the same bottom crossbeam 3. This further ensures stability.

[0027] The base frame is a rhomboid steel frame structure, including a bottom stabilizing beam 4 that serves as one side of the rhombus, and a bottom crossbeam 3 that is fixedly fitted to the bottom stabilizing beam 4 as one diagonal of the rhomboid steel frame. This ensures the stability under stress.

[0028] A steel frame is welded and fixed between the top corner of the base frame and the bottom crossbeam 3, forming another diagonal of the rhomboid steel frame. This ensures the stability of the load-bearing structure.

[0029] The working principle of this utility model: First, select appropriate angle steel according to the dimensions of the box-shaped steel float 8 and the hanging grid 9. The height of the column 1 must be greater than the height of the hanging grid 9 to ensure that the hanging grid 9 does not touch the ground. Then, the column 1, the top crossbeam 2, the bottom crossbeam 3, the diagonal bar 5, the diagonal brace 6, and the bottom stabilizing beam 4 are welded to form a stable trapezoidal support frame to ensure that the float will not tilt or slide during hoisting and maintenance. A certain gap is reserved between the two support frames. The width of this gap is greater than the width of the hanging grid 9 to ensure that the hanging grid 9 can pass through the gap smoothly. Finally, adjust the spacing of the two sets of load-bearing supports according to the length of the float and arrange them symmetrically front and back. First, the box-shaped steel drift barrier float 8 is lifted from the water using hoisting equipment. Then, the float's hanging grid 9 is passed through the gap between two trapezoidal support brackets, allowing the box-shaped steel drift barrier float 8 to be placed on the support brackets. The box-shaped steel drift barrier float 8 is suspended from the base frame by the support brackets. The anti-slip rubber pads 7 on the surface of the top crossbeam 3 can reduce the sliding friction between the float and the support brackets, protect the anti-corrosion paint on the surface of the float, and improve the stability and safety of the float placement. Because the float is suspended in mid-air and its bottom does not contact the ground, damage to the float structure or the surface anti-corrosion paint is avoided. At the same time, the space at the bottom and sides of the float is more spacious, facilitating inspection and maintenance by personnel. Maintenance personnel can inspect various parts of the float, including its structural integrity, the condition of the anti-corrosion paint, and the sturdiness of the mounting grilles. If necessary, damaged parts can be repaired or replaced.
