Problems solved by technology

[0003] At present, concrete tamping rods are often used in construction to vibrate and artificially lighten the surface. Due to the small volume of concrete and large surface area, the quality of vibration is uncontrollable, and the efficiency of artificial lightening is low, which easily causes cracks on the concrete surface and high cost

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings:

[0014] like figure 1 A concrete leveling machine for a closed layer of a railway track is shown. When arranging the tooling, a hoist is installed in front of the device to connect the traction hook 12 through a wire rope and provide traction for the entire device. On the supporting layer, the screed 11 is placed on the concrete layer to be leveled, and the second roller 14 can be adjusted in width through bar bolts and bolted connection, and is connected with the edge of the supporting layer in vertical rolling, so as to realize the device in Due to the limiting effect in the width direction, during the movement, the vibrator 8 vibrates and drives the leveling plate 11 to move along the laying direction of the concrete layer to be leveled under the traction of the hoist.

[0015] A railway track closed layer concrete leveling machine is fixedly connected with second t...

Abstract

The invention discloses a railway track closing layer concrete leveling machine. The machine comprises second telescopic rods fixedly connected to the two ends of a crossbeam and is characterized in that first telescopic rods fixedly connected to the crossbeam are arranged between the second telescopic rods and are in sliding connection with first rod pieces, the second telescopic rods are in sliding connection with second rod pieces, the bottoms of the first rod pieces are rotationally connected with a leveling board through rotary pieces, the leveling board is used for adjusting the levelingangle and provided with a vibrator, and second rolling wheels used for limitation are horizontally installed on the edge portions on the two sides of the leveling board. The surface of a concrete closing layer is highly leveled through the vibrator and the leveling board capable of rotating at a certain angle, meanwhile, the leveling angle is adjustable, the drainage effect of a drainage surfaceis remarkably improved, meanwhile the machine is easy and convenient to operate, the number of operation personnel is small, and labor intensity is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of concrete leveling machines, in particular to a concrete leveling machine for a closed layer of a railway track. Background technique [0002] With the development and construction of high-speed railway, the concrete sealing layer is regarded as the key structure of high-speed railway foundation and bridge deck waterproofing and drainage. Its surface flatness and drainage slope rate directly affect the drainage effect and the visual quality of the project. It is a "V" type drainage slope, and the longitudinal section surface determines the drainage direction according to the longitudinal slope of the line. [0003] At present, concrete tamping rods are often used in construction to vibrate and artificially polish the surface. Due to the small volume and large surface area of ​​concrete, the quality of vibrating is uncontrollable, and the efficiency of artificial polishing is low, which is easy to cause cra...
