[0001] This utility model belongs to the technical field of sound barrier construction, specifically relating to a hoisting fixture for a high-speed rail sound barrier unit panel. Background Technology

[0002] During the construction of high-speed railways, the installation of sound shield unit panels is a crucial step in ensuring noise control during train operation. Due to the large size and numerous number of sound shield unit panels required, traditional hoisting methods often employ simple binding or clamping. These clamping structures or methods are complex, causing significant inconvenience and resulting in low installation efficiency, thus reducing the overall construction efficiency of high-speed railways.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0023] like Figure 1 As shown, a high-speed rail sound screen unit panel hoisting fixture includes a main body 1 and an extrusion part 2. The main body 1 is a downward-opening square groove made of welded metal plates. The width of the square groove is adapted to the thickness of the sound screen unit panel, so that the upper edge of the sound screen unit panel can be clamped from top to bottom.

[0024] In this embodiment, the length of the main body 1 is 30-80cm, and the groove depth is 10-20cm.

[0025] The square groove is equipped with an extrusion component 2, which is an inverted L-shaped structure. It can be made of steel plate. Ribs are provided at the corners of the extrusion component 2. The corners of the extrusion component 2 are hinged to the inner wall of one side of the main body 1 by a hinge plate. There is a certain distance between the hinge plate and the top of the main body 1, so that the upper end of the extrusion component 2 has enough space to turn upward.

[0026] The lower end of the extrusion piece 2 is hinged to the middle of the extrusion plate 3, and the upper end of the extrusion piece 2 is connected to the lifting cable 4. The lifting cable 4 passes upward through the main body 1 and is connected to the hoisting device to provide driving force. In response to the upward pulling of the extrusion piece 2, the extrusion plate 3 clamps the sound screen unit plate under the action of the weight of the main body 1. As it continues to be lifted, the sound screen unit plate and the extrusion plate 3 generate sufficient friction, and the friction is used to pull the extrusion piece 2 tighter, thereby using its own weight to tightly clamp the sound screen unit plate and prevent the sound screen unit plate from falling off.

[0027] In an optional embodiment, the main body 1 has a through hole in the middle corresponding to the lifting cable 4, and the hole diameter is larger than the displacement distance of the extruder 2 in the horizontal direction, so as to ensure that the lifting cable 4 will not be rubbed through the hole.

[0028] Furthermore, the length of the extrusion plate 3 is adapted to the length of the main body 1, and the lower edge of the extrusion plate 3 is at the same height as the lower edge of the main body 1. Two extrusion members 2 are provided inside the main body 1, and the two extrusion members 2 are respectively hinged to both ends of the extrusion plate 3, thereby improving the clamping capacity and ensuring the force balance and stability of the clamping.

[0029] The two ends of the lifting cable 4 are respectively connected to two extrusion parts 2. Specifically, the length of the lifting cable 4 is greater than the distance between the two extrusion parts 2, so that it can pass downward through the perforation and connect to the two extrusion parts 2. The lifting ring 5 is connected to the hoisting device, which can be a crane, winch, etc. The lifting ring 5 is connected to the steel cable of the hoisting device. The two extrusion parts 2 are driven simultaneously through the lifting ring 5. The lifting cable 4 is a steel wire rope. The inner diameter of the lifting ring 5 is larger than the diameter of the lifting cable 4, so that it can be slidably assembled in the middle of the lifting cable 4. When pulling the lifting ring 5, the lifting ring 5 can slide independently to ensure the force balance of the two extrusion parts 2, thereby avoiding unstable clamping of the sound screen unit board.

[0030] In an optional embodiment, the upper end of the extrusion member 2 extends toward the side of the top plate of the main body 1 away from its hinge point, thereby maximizing the torque of the extrusion member 2. Specifically, after clamping the sound screen unit board, the lifting point of the extrusion member 2 is located at the center line of the sound screen unit board, thereby ensuring that the sound screen unit board remains as vertical as possible after being lifted, thus reducing the difficulty of installation.

[0031] The upper surface of the main body 1 is provided with sliding rollers 7 corresponding to both sides of the lifting cable 4. The sliding rollers 7 can guide the lifting cable 4 and avoid friction between the lifting cable 4 and the perforation, thereby improving the service life. The two ends of the sliding rollers 7 are provided with hinge plates fixed to the upper surface of the main body 1, and the two ends of the sliding rollers 7 are rotatably connected to the two hinge plates.

[0032] In an optional embodiment, both the extrusion plate 3 and the inner wall of the main body 1 are provided with anti-slip pads 6 corresponding to the sound screen unit plate. The anti-slip pads 6 are rubber layers, thereby improving the friction.

[0033] A hinge plate is provided on the side of the extrusion plate 3 away from the sound shield unit board. The hinge plate is positioned towards the upper edge of the extrusion plate 3. Specifically, the hinge plate is located on the side of the extrusion plate 3 close to the upper edge of the extrusion plate 3 along the center line. As a result, under its own weight, the lower end of the extrusion plate 3 will tilt outward, which facilitates the insertion of the sound shield unit board and reduces the difficulty of clamping.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
