Description

Technical Field

[0001] The utility model belongs to the technical field of track plate installation equipment, and particularly relates to a ballastless track plate lifting bracket. Background Art

[0002] Track slabs refer to new sub-rail components with a plate structure that are used to support and fix rails and distribute the load transmitted by the train through the rails to the base under the slabs. When laying track slabs, a slab laying machine is generally used for the laying work. However, during the laying process of track slabs, gaps and offsets are inevitable. At this time, the track slabs need to be adjusted, and the traditional adjustment method mostly uses jacks to complete it.

[0003] However, the existing jack adjustment method has the following disadvantages:

[0004] 1. It is inconvenient to quickly lift and translate the track plate, which results in time-consuming and labor-intensive adjustment of the track plate and low work efficiency.

[0005] 2. When the track plate is lifted and translated for adjustment, the track plate does not have a limit fixing function, which may easily cause the track plate to continue moving forward due to inertia during the translation process and slide off the lifting and translation frame, thereby causing unnecessary losses. Summary of the Invention

[0006] To solve the problems raised in the above background technology. The utility model provides a ballastless track slab lifting bracket, which uses a hydraulic rod to drive an L-shaped lifting arm to quickly lift the ballastless track slab. The linear electric slide rail and the electric slide table are used to facilitate the rapid lifting and translation of the track slab, thereby improving construction efficiency. The cylinder drives the limit clamping plate to move the slider in the slide groove to limit the clamping of the ballastless track slab, preventing the L-shaped lifting arm from slipping and causing losses during the lifting and translation of the ballastless track slab.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ballastless track plate lifting bracket, comprising a moving body, a base connected to the front end of the moving body, a linear electric slide installed on the middle part of the base, a lifting mechanism provided on the horizontal drive of the linear electric slide, the lifting mechanism comprising an electric slide, a hydraulic rod, a lifting platform, and a lifting arm, an L-shaped lifting arm provided at the front end of the lifting platform, the lifting platform is installed on the electric slide through a hydraulic rod, and a limiting clamping structure is provided on the front end of the L-shaped lifting arm.

[0008] As a preferred solution, the limit clamping structure includes a cylinder and a limit clamping plate. The cylinder is arranged on the inner end of the slide groove at the front end of the L-shaped lifting arm. The bottom of the limit clamping plate slides on the slide groove through a slider, and the telescopic end of the cylinder is connected to the slider at the bottom of the limit clamping plate.

[0009] As a preferred solution, the limit clamping plate is driven by a cylinder to move horizontally on the L-shaped lifting arm through a slide groove.

[0010] As a preferred solution, the electric slide is driven and installed on a linear electric slide rail, and the mobile body is provided with a motor driver for driving the electric slide to translate on the linear electric slide rail.

[0011] As a preferred solution, limit guide rods are provided on both ends of the electric slide, the lifting platform is slidably connected to the limit guide rods through limit guide holes, and a top plate is provided on the top of the limit guide rods.

[0012] As a preferred solution, a control switch box is provided on the mobile body via a push handle bracket.

[0013] As a preferred solution, a driving wheel is provided at the bottom of the mobile body, and a moving wheel is provided at the bottom of the front end of the base.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model drives the L-shaped lifting arm through the hydraulic rod to quickly lift the ballastless track plate, and utilizes the linear electric slide rail and the electric slide table to facilitate the rapid lifting and translation of the track plate, thereby improving construction efficiency.

[0016] The motor driver is used to drive the electric slide to move horizontally forward on the linear electric slide until the L-shaped lifting arm is inserted into the bottom of the ballastless track slab for support, so that one side of the ballastless track slab is close to the clamping pad. The front end of the L-shaped lifting arm is exposed to the limit clamping plate and stops. The limit clamping plate is driven by the cylinder to move in the slide groove through the slider to limit the clamping of the ballastless track slab. The hydraulic rod drives the lifting platform to move upward along the limit guide rod to prevent the L-shaped lifting arm from sliding and causing losses during the lifting of the ballastless track slab and the translation process.
