Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering aqueduct construction technology, specifically relating to a horizontal material transport device for a high-pier, long-distance U-shaped thin-walled aqueduct. Background Technology

[0002] In the construction of long-distance U-shaped thin-walled aqueducts with high piers, the traditional method of concrete placement is mainly by using trailer pumps. The trailer pumps are placed at the bottom of the piers, and the pump pipes extend along the pier body to the aqueduct body. During the pouring process, due to the long length of the pump pipes, problems such as pipe blockage are prone to occur. In addition, the placement of trailer pumps is greatly affected by the site, resulting in relatively low material transportation efficiency. Furthermore, the use of traditional material transportation methods is often accompanied by the risks of working at height. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a horizontal material transport device for a long-distance U-shaped thin-walled aqueduct with high piers that can realize continuous horizontal transport from external loading to internal unloading, reduce the risks of pumping and hoisting, and improve the efficiency and safety of casting.

[0004] The technical solution of this utility model is as follows: a horizontal material transport device for a high-pier, long-distance U-shaped thin-walled aqueduct, comprising: a transport track, a track foundation, a loading platform, and a track trolley. The transport track is fixed inside the aqueduct body. The track foundation is located on the outer side of the aqueduct end. An external steel rail is installed on the track foundation and is flush with the transport track inside the aqueduct body. The loading platform is integrally cast with the outer side of the starting end of the track foundation. The external steel rail extends to the loading platform. The track trolley runs on the transport track and the external steel rail. The transport track includes: two steel rails, several sleepers, angle steel clamps, steel plates, and rubber pads. The rubber pads are placed above the concrete surface of the aqueduct body and are tightly fitted with the steel plates. The steel plates are fixedly connected to the bottom of the sleeper beams. The angle steel clamps are fixedly connected to the top of the sleeper beams and the sides of the steel rails, respectively. The bottom end of the steel rail is clamped to the top end of the sleeper beam by the angle steel clamps.

[0005] Furthermore, the distance between the two rails is 1.255m, the overlap between the rail and the outer rail is fixed by a connecting plate, and limiters are provided at both ends of the rail and the outer rail.

[0006] Furthermore, the sleepers are arranged at 1.2m intervals along the inner side of the aqueduct.

[0007] Furthermore, several angle steel clips are respectively provided on both sides of the contact surface between the sleeper beam and the rail, with a spacing of 0.12m between each angle steel clip.

[0008] Furthermore, the loading platform is arranged on a slope with a top height of 1.15m.

[0009] The beneficial effects of this utility model are: 1. High transportation efficiency: By connecting the transport track inside the aqueduct with the external track foundation, and with the help of the loading platform and track trolley, continuous horizontal transportation with loading on the outside and unloading on the inside can be achieved, avoiding problems such as high energy consumption and easy pipe blockage caused by long-distance pumping, and greatly improving the efficiency of concrete transportation.

[0010] 2. High construction safety: This device avoids the use of high-altitude hoisting and long-distance pumping, reducing the number of personnel operating at heights or in dangerous areas, thereby reducing construction safety risks.

[0011] 3. Reasonable structural stress: Rubber pads and steel plates are set as transition layers during track laying, which can effectively disperse and buffer track loads, avoid point pressure damage and vibration concentration, and protect the safety of the U-shaped thin-walled aqueduct body structure.

[0012] 4. Easy and stable installation: The combination of sleepers, angle steel clips and rails simplifies the track installation process and ensures a firm and reliable connection. It facilitates rapid laying and adjustment in long aqueducts, resulting in high construction efficiency.

[0013] 5. Strong adaptability and versatility: The loading platform adopts a sloping layout with a reasonable top height (1.15 m), which can be smoothly connected with conventional concrete mixer trucks; the track gauge (1.255 m) and sleeper spacing (1.2 m) design ensures the smooth operation of the trolley and is suitable for aqueduct projects with different spans and construction conditions.

[0014] 6. Safe and reliable operation: Limiters are installed at the ends of both the transport track and the external rails to effectively prevent the trolley from going over the end, ensuring safe and controllable operation. Attached Figure Description

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figure 1-5 As shown, a horizontal material transport device for a long-distance, high-pier U-shaped thin-walled aqueduct includes a transport track 1, a track foundation, a loading platform 2, and a track trolley 3. The transport track 1 is fixedly installed inside the aqueduct body. The track foundation is cast-in-place on the outer side of the aqueduct end, and external steel rails are laid on it. The external steel rails are flush with the transport track 1 inside the aqueduct body in terms of elevation and direction. The loading platform 2 is integrally cast with the outer side of the starting end of the track foundation, and adopts a sloping structure with a top height of approximately 1.15m, facilitating the loading of materials from road concrete mixer trucks onto the track trolley 3. The external steel rails extend onto the loading platform 2, and the track trolley 3 can freely move between the transport track 1 and the external steel rails, realizing continuous horizontal transport of materials.

[0023] The transport track 1 specifically includes: two parallel steel rails 11, several sleepers 12, angle steel clamps 13 (∠50 angle steel), steel plates 14, and rubber pads 15. The rubber pads 15 are placed above the inner surface of the concrete of the aqueduct body, serving as a buffer and distributing pressure evenly. Steel plates 14 are tightly laid on top of the pads, and the steel plates 14 are welded to the bottom of the sleeper beams 12. The sleepers 12 are preferably 16b channel steel, and are arranged every 1.2m along the longitudinal direction of the aqueduct. The steel rails 11 are fixed to the sleeper beams 12, and their bottoms are clamped by angle steel clamps 13. The angle steel clamps 13 are arranged on both sides of the contact surface between the sleeper beam and the rail, with a spacing of 0.12m between adjacent angle steel clamps 13 to ensure the stability of the rails. Adjacent rail sections 11 are joined and fixed by connecting plates 16. The joint between rail 11 and the external rail is also fixedly connected by connecting plates 16. Limiters are installed at both ends of the transport track 1 and the external rail to prevent the rail trolley 3 from derailing. Preferably, the track gauge between the two rails 11 is 1.255m to ensure smooth operation of the rail trolley.

[0024] The railcar 3 is a dedicated rail-mounted concrete transport vehicle with a tank volume of approximately 8m³. Its wheels are matched with the steel rails 11, enabling it to reciprocate between the transport rail 1 and the external steel rails. During construction, the concrete mixer truck stops at the ramp end of the loading platform 2 and unloads the concrete directly into the tank of the railcar 3. The railcar 3 then runs along the transport rail 1, transporting the concrete to the designated pouring location inside the aqueduct for unloading, completing one transport cycle.

[0025] During operation, the track, sleepers, steel plates, rubber pads, and concrete trough form a "rigid-flexible" load-bearing system. This system ensures the stability of the track's geometric alignment while effectively mitigating the concentrated effects of dynamic loads on the thin-walled trough, preventing localized damage. This device enables efficient, safe, and stable transportation of concrete during the construction of long-distance aqueducts with high piers, reducing the risks associated with long-distance pumping and high-altitude hoisting, and significantly improving construction efficiency and project quality.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made to it.
