Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a transport device for bridge segments. Background Technology

[0002] A bridge is an architectural structure used to cross obstacles such as rivers, straits, valleys, roads, or other barriers to allow pedestrians, vehicles, trains, or pipelines to pass. The main components of a bridge include the span structure, piers, abutments, and bearings. The span structure is the main load-bearing part of the bridge, spanning the obstacle and supporting the traffic load on the bridge deck. Piers and abutments are the supporting structures of the bridge, transferring the load of the span structure to the foundation. Bearings are located between the span structure and the piers or abutments, used to transfer loads and allow the bridge to deform to a certain extent under the influence of temperature changes, wind loads, etc.

[0003] Currently, bridge construction typically employs a splicing method, requiring the transportation of bridge components. When transporting semi-circular bridge segments, ropes are usually used to secure them to the transport vehicle. However, the small contact area between the ropes and the curved surface of the bridge segment makes it prone to slipping during vehicle bumps or sudden braking, increasing the risk of transportation. To address this issue, we propose a bridge segment transportation device. Utility Model Content

[0004] The purpose of this invention is to provide a transportation device for bridge segments to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bridge segment transport device includes a base. Multiple dampers are fixedly connected to the upper surface of the base. A support plate is fixedly connected to the upper surface of each damper. Two sliding plates are fixedly connected to the bottom surface of the support plate. Two bearings are embedded in the outer surface of each sliding plate. A bidirectional threaded rod is fixedly connected to the inner ring of each pair of bearings. A motor is fixedly connected to the outer surface of each sliding plate. The output end of each motor is connected to the outer surface of the bidirectional threaded rod. Two sliders are threadedly connected to the outer surface of each bidirectional threaded rod. A clamping plate is fixedly connected to the upper surface of each slider. A hydraulic push rod is fixedly connected to the outer surface of the support plate. A push plate is fixedly connected to the output end of the hydraulic push rod. A receiving plate is fixedly connected to the upper surface of the support plate.

[0007] In a further embodiment, a plurality of sliding cylinders are fixedly connected to the upper surface of the base, and a support rod is slidably connected to the inner sidewall of each sliding cylinder, and the upper surface of each support rod is connected to the bottom surface of the support plate.

[0008] In a further embodiment, a plurality of elastic elements are fixedly connected to the upper surface of the base, and the outer surface of each elastic element is connected to the bottom surface of the support plate.

[0009] In a further embodiment, the upper surface of the support plate is provided with a plurality of sliding holes, and each sliding hole is slidably connected to a ball bearing on its inner sidewall.

[0010] In a further embodiment, the outer surface of the receiving plate and the outer surface of the support plate are jointly and fixedly connected to two sliding rods, and the outer surface of each sliding rod is slidably connected to the inside of the push plate.

[0011] In a further embodiment, the push plate, the receiving plate, and the two sets of clamping plates are all fixedly connected with rubber pads.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a motor to drive a bidirectional threaded rod to rotate, causing the slider to move the clamping plates closer together or further apart. The four clamping plates can clamp multiple points on the bridge segment. In conjunction with the hydraulic push rod, the push plate is moved to clamp the bridge segment between the push plate and the receiving plate, thereby achieving multi-faceted clamping and fixing of the semi-circular bridge segment, making it less prone to slippage. With the addition of a damper, it can provide shock absorption and buffering for the bridge segment, reducing the impact of vehicle bumps on the bridge segment. Attached Figure Description

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4In this utility model, a transport device for bridge segments includes a base 1. Multiple dampers 2 are fixedly connected to the upper surface of the base 1. A support plate 3 is fixedly connected to the upper surface of each damper 2. Two sliding plates 4 are fixedly connected to the bottom surface of the support plate 3. Two bearings 5 ​​are embedded in the outer surface of each sliding plate 4. A bidirectional threaded rod 6 is fixedly connected to the inner ring of each pair of bearings 5. A motor 7 is fixedly connected to the outer surface of each sliding plate 4. The output end of each motor 7 is connected to the outer surface of the bidirectional threaded rod 6. Two sliders 8 are threadedly connected to the outer surface of each bidirectional threaded rod 6. A clamping plate 9 is fixedly connected to the upper surface of each slider 8. A hydraulic push rod 10 is fixedly connected to the outer surface of plate 3. A push plate 11 is fixedly connected to the output end of the hydraulic push rod 10. A receiving plate 12 is fixedly connected to the upper surface of the support plate 3. The bidirectional threaded rod 6 is rotated by the motor 7, which causes the slider 8 to move the clamping plates 9 closer or further apart, thus clamping multiple points of the bridge segment. The push plate 11 is moved by the hydraulic push rod 10, clamping the bridge segment between the push plate 11 and the receiving plate 12. This enables multi-faceted clamping and fixing of the semi-circular bridge segment, making it less prone to slippage. The damper 2 provides shock absorption and buffering for the bridge segment, reducing the impact of vehicle bumps on the bridge segment.

[0023] Multiple sliding cylinders 13 are fixedly connected to the upper surface of the base 1. Each sliding cylinder 13 has a support rod 14 slidably connected to its inner side wall. The upper surface of each support rod 14 is connected to the bottom surface of the support plate 3. Multiple elastic elements 15 are fixedly connected to the upper surface of the base 1. The outer surface of each elastic element 15 is connected to the bottom surface of the support plate 3. Through the cooperation of the sliding cylinders 13, support rods 14 and elastic elements 15, the support plate 3 can only move up and down, thus preventing the support plate 3 from being misaligned.

[0024] The upper surface of the support plate 3 is provided with multiple sliding holes 16. Each sliding hole 16 has a ball bearing 17 slidably connected to its inner sidewall. The outer surface of the receiving plate 12 and the outer surface of the support plate 3 are fixedly connected with two sliding rods 18. The outer surface of each sliding rod 18 is slidably connected to the inside of the push plate 11. The push plate 11, the receiving plate 12 and the two sets of clamping plates 9 are all fixedly connected with rubber pads. Through the cooperation of the sliding holes 16 and the ball bearings 17, the friction between the bridge segment and the support plate 3 can be changed to rolling friction, reducing the resistance caused by friction during positioning and movement. By setting two sliding rods 18, the push plate 11 can be limited to prevent the push plate 11 from tilting and misaligning when pushing the bridge segment.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the semi-circular bridge segment is placed in the middle of the clamping plate 9, and the motor 7 is turned on to drive the bidirectional threaded rod 6 to rotate. With the limiting of the sliding plate 4, the slider 8 drives the clamping plate 9 to move closer or further away from each other, thereby clamping multiple points of the bridge segment. When the motor 7 rotates, the hydraulic push rod 10 is turned on to drive the push plate 11 to move, clamping the bridge segment between the push plate 11 and the receiving plate 12, thereby achieving multi-faceted clamping and fixing of the semi-circular bridge segment.
