Description

Technical Field

[0001] This utility model relates to the field of concrete vibration technology, specifically to a leveling and vibration device for waterproof protective layers of high-speed railway bridges. Background Technology

[0002] In high-speed railway construction, ballastless track has gradually replaced ballasted track due to its superior durability, stability, and lower maintenance requirements, becoming the primary track type for high-speed railways. Among these factors, the construction quality of the bridge waterproofing protective layer plays a crucial role in the stability and service life of the track structure. A good waterproofing protective layer can effectively guide rainwater away from the track structure, reduce water penetration, and prevent damage and corrosion to the track foundation and internal structure due to long-term water accumulation.

[0003] Currently, the waterproofing system between the base plates of the two tracks on high-speed railway bridges typically consists of polymer-modified bitumen waterproofing membrane, steel mesh, and a reinforced concrete protective layer. The protective layer is equipped with double-sided transverse drainage slopes to achieve drainage. However, existing construction techniques have several drawbacks. On the one hand, the control of slope and thickness during the construction of the protective layer concrete largely relies on manual operation, which easily leads to insufficient concrete thickness and drainage slope, as well as inadequate control of flatness. On the other hand, in the vibration and finishing stage of the waterproof protective layer concrete, conventional construction uses simple plate vibrators for direct vibration, followed by manual finishing and smoothing. This is not only inefficient but also prone to over-vibration and under-vibration, making the construction quality heavily dependent on the skill level of the workers. Therefore, in the leveling and vibration construction of the waterproof protective layer of high-speed railway bridges, how to achieve uniform concrete distribution, improve vibration and finishing efficiency, and adjust the drainage slope are key technical problems that urgently need to be solved. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model aims to propose a leveling and vibrating device for the waterproof protective layer of high-speed railway bridges. The device moves by means of an electric motor drive and a moving component. The longitudinal and transverse slopes of the base plate are adjusted by means of a ball joint pressure plate at the lower end of the screw, and mechanical vibration is provided by a vibrator. This solves problems such as uneven material distribution, insufficient vibration depth, low degree of mechanization, and difficulty in controlling the transverse and longitudinal slopes of the waterproof protective layer of the bridge deck.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A leveling and vibrating device for waterproof protective layers of high-speed railway bridges includes a motor, fixed piles, a wire rope, a moving component, pulleys, a frame beam, a screw rod, a vibrator, a base plate, and a slide rail. The frame beam includes crossbeams and longitudinal beams, which are fixedly connected. An upper moving component and pulleys are located at the lower part of the frame beam, and the upper moving component and pulleys are fixedly connected to the lower part of the frame beam. The frame beam is connected to the base plate via the screw rod. A slide rail is located in the middle of the base plate, and a vibrator is mounted on the slide rail. Side moving components are located on both sides of the base plate. The wire rope passes through the pulleys of the leveling and vibrating device, and its two ends are fixed to the motor and the fixed pile, respectively. The motor drives the automatic movement of the vibrating and leveling device.

[0007] In practical applications, the distance between the base plate and the frame beam is adjusted by a screw rod, and the angle of the base plate is adjusted by a ball joint pressure plate to ensure that the angle between the base plate and the waterproof protective layer is consistent with the design transverse and longitudinal slopes. The contact force between the leveling vibrator and the base plate is adjusted by a tension spring to ensure that the rollers are in close contact with the base plate under force. The vibrator is connected to the fixed pile and the motor by a steel wire rope. During construction, the leveling vibrator is aligned with the height of the base plate of the ballastless track, and the base plate is in close contact with the concrete surface. The steel wire rope is tightened by the motor, causing the leveling vibrator to move longitudinally along the bridge. During the movement, the leveling and vibration of the concrete are achieved through the base plate and the vibrator.

[0008] Furthermore, the frame beams and longitudinal beams are distributed in parallel, and through holes slightly larger than the diameter of the lead screw are provided at the connection points for installing the lead screw.

[0009] Furthermore, four upper moving components are symmetrically arranged longitudinally in the overlapping area of ​​the frame beam and the base plate. Each upper moving component includes a roller, a roller bracket, a fixing bolt, and a spring. The roller is connected to the roller bracket, and the fixing bolt is fixed to the lower end of the frame beam. The roller is connected to the frame beam through the fixing bolt, and the spring is arranged between the frame beam and the roller bracket, allowing the leveling and vibrating device to be used at different application heights.

[0010] Furthermore, the frame beam and the base plate are connected by the screw to adjust the vibration depth. The end of the screw that contacts the base plate is connected to the ball joint pressure plate, which is fixed on the base plate and can be used to adjust the tilt angle of the base plate.

[0011] Furthermore, the base plate should be consistent with the designed transverse slope, and the front end of the base plate should be upturned to prevent concrete from entering the upper area of ​​the base plate.

[0012] Furthermore, the side-moving assembly includes a side roller, a side roller bracket, a tension spring, and a fixing bolt. The fixing bolt is fixedly connected to the base plate. One end of the side roller bracket is hinged to the fixing bolt, and the other end is connected to the side roller. The tension spring is provided at the middle position between the side roller brackets to adjust the distance and contact force between the device and the base plate.

[0013] Furthermore, the pulleys should be positioned on the same vertical projection plane at the frame beam and the base plate.

[0014] Furthermore, a limiting bolt is provided on the slide rail to limit the movement range of the vibrator on the slide rail.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this application, the longitudinal and transverse slope of the base plate can be adjusted by means of a ball joint pressure plate and a ball screw, which can ensure that the angle between the base plate and the waterproof protective layer is consistent with the design transverse and longitudinal slope. This effectively solves the problem that in traditional construction, slope and thickness control depends on manual operation, which can easily lead to insufficient concrete thickness and drainage slope, and inadequate flatness control.

[0017] 2. In this application, mechanical vibration using a vibrator replaces the conventional method of directly vibrating with a simple plate vibrator followed by manual finishing and smoothing, avoiding problems such as over-vibration and under-vibration, and ensuring uniform and dense concrete compaction. Simultaneously, the automatic movement of the leveling and vibrating device is achieved through electric motor drive and wire rope connection, significantly improving work efficiency, construction convenience and safety, and reducing the dependence of construction quality on the operator's skill level.

[0018] 3. In this application, the spring in the upper moving assembly and the tension spring in the side moving assembly can adjust the contact force between the device and the base plate, ensuring that the roller and the base plate are in close contact under force, thereby enhancing the applicability and flexibility of the device in different construction scenarios.

[0027] In this embodiment, four upper moving components 9 are symmetrically arranged longitudinally in the overlapping area of ​​the frame beam 7 and the base plate 1.

During implementation, the compaction finishing effect is observed, and the compaction depth is strictly controlled by adjusting the lead screw length to ensure optimal finishing results.
