The concrete pouring elevation control device of the track bed of the ballastless track comprises beams arranged on steel rails on two sides, and shoulder pole type vertical posts arranged below two ends of the beams and tightly attached to the outer sides of the steel rails, wherein pushing and scratching shovel plates are fixed on the outer sides of the terminal ends of the two shoulder pole type vertical posts; the beams and the shoulder pole type vertical posts are arranged vertically to each other, and the shoulder pole type vertical posts and the pushing and scratching shovel plates are arranged vertically to each other; a pushing and scratching oblique surface having an angle of 45 degrees with the horizontal direction is arranged on the front end of each pushing and scratching shovel plate; the beams and the shoulder pole type vertical posts are welded in a hollow manner. The concrete pouring elevation control device of the track bed of the ballastless track is simple in structure, low in manufacturing cost, and convenient as well as easy to operate, can ensure construction accuracy, avoids system error and operating error in the measurement, improves work efficiency, works flexibly, is wide in application range and achieves certain promotional value as well as use value.
Description
Technical field
The utility model relates to railway tunnel Construction of Ballastless Track field, is specially a kind of used for ballastless track bed concrete pouring elevation control device.
Background technology
In railway tunnel construction is built, super long tunnel (more than 10km) railway roadbed is generally all designed to non-fragment orbit solid concrete roabed, in railway roadbed concrete pouring construction, elevation control becomes the thing of operating personnel's headache, for meeting rapid construction, guarantee that railway roadbed cast-in-situ concrete absolute altitude meets designing requirement, the general measuring apparatus that adopts is drawn in design elevation in construction operation template, to carry out dipstick metering control, in construction, in order to ensure gauge, meet the specific (special) requirements of design 1435mm, concrete slab sleeper is to adopt prefabricate form to transport to scene, tunnel, construct when ballastless track bed, for guaranteeing that concrete slab sleeper is placed in cast-in-situ concrete railway roadbed like clockwork, each size meets design, both sides concrete slab sleeper must be installed rail and form track-panel type, just can build ballastless track bed, cast-in-situ concrete railway roadbed absolute altitude is calculated and is drawn by rail level design altitude.With measuring apparatus measurement, control, with the control point of measuring, measure certain size and control railway roadbed absolute altitude, every 56cm(concrete slab sleeper spacing) must survey 1 point, left and right two rails are exactly 2 points, and point is many, measurement is wasted time and energy, and concreter's operate miss is large, labour intensity is large, construction coordinates difficulty, and work efficiency is low, and speed of application is slow.
Summary of the invention
The utility model is controlled difficulty in order to solve existing tunnel used for ballastless track bed concrete pouring absolute altitude, measures the problems such as input personnel are many, labour intensity is large, efficiency is low, and a kind of used for ballastless track bed concrete pouring elevation control device is provided.
The utility model is to adopt following technical scheme to realize: used for ballastless track bed concrete pouring elevation control device, comprise the crossbeam that is set up on the rail of both sides, be arranged on below, crossbeam two ends and be close to the carrying pole type column in rail outside, two carrying pole type column ends outside is fixed with and pushes shovel board, crossbeam and carrying pole type column and carrying pole type column with push all vertical settings of shovel board.The height of described carrying pole type column, for design rail surface elevation deducts railway roadbed design elevation and the thickness that pushes shovel board, adopts this structure design, and people can control concrete road bed absolute altitude according to actual conditions.Adopt structure design of the present utility model, in used for ballastless track bed concrete pouring operation, at concrete, vibrate and with this device, between sleeper, carry out front and back after meeting compactness and push shovel board, push-and-pull is scraped to even out and with trowel, is closed flat and can meets design requirement afterwards.
In order further to optimize the structure of this elevation control device, improve its function, the utility model has also carried out following structure design:
The described shovel board front end that pushes is provided with and is the inclined-plane that pushes of 45 ° with horizontal direction, is convenient to push concrete adhesion in shovel operation, is convenient to concreter's operation simultaneously, and workman's operation is also more convenient.
Described crossbeam and carrying pole type column are welded into hollow shape, can alleviate the weight of whole control device, are convenient to operation.
Compared with prior art, the utility model is applied in the ballastless track bed concrete construction railway roadbed of Large Railway Tunnel absolute altitude and controls in operation, between per pass bed board, once push shovel operation, can complete absolute altitude controls, precision can be controlled in 1mm ~ 2mm, meet design specifications and construction test standard requirement, use this to install two people and get final product complete operation, control simple, easily go, speed of application is accelerated greatly, and can greatly reduce labour, reduce labour intensity, and precision is high, operation is reliable, steadily, can complete quickly and accurately railway roadbed concrete casting elevation controls, rural migrant worker's operation has been removed to calculating especially, the sport technique segment of dipstick metering, material therefor can utilize corner, job site material, do not need to increase construction cost, the utility model is simple in structure, cost of manufacture is low, easy and simple to handle, can guarantee that construction accurately, systematic error and operate miss in measuring have been avoided, improve work efficiency, operating flexibility, applied widely, there is certain promotional value and use value.

The specific embodiment
Used for ballastless track bed concrete pouring elevation control device, as shown in Figure 1, 2, comprises the crossbeam 2 that is set up on both sides rail 1, is arranged on below, crossbeam two ends and is close to the carrying pole type column 3 in rail outside, crossbeam 2 and carrying pole type column 3 are welded into hollow shape.Two carrying pole type column ends outside is fixed with and pushes shovel board 4, crossbeam and carrying pole type column and carrying pole type column with push all vertical settings of shovel board.Push shovel board 4 front ends be provided with horizontal direction be 45 ° push inclined-plane 5.
During concrete making, crossbeam and carrying pole type column are welded into hollow shape with angle steel or steel plate, can be processed by job site steel leftover pieces, cut the waste, square steel crossbeam is about 260cm ~ 280cm, wide 20cm, thick 12cm, carrying pole type rectangle column width, thickness are consistent with crossbeam, described carrying pole type refers to that spacing meets the wide size of two rails outer rail, pushes the long 50cm of shovel board, wide consistent with crossbeam, thick 6 ~ 8cm, pushing shovel board is that a monoblock steel plate is made.
During operation, by 2 people, can be completed, after railway roadbed concrete meets compactness by the operation of vibrating, push shovel operation, during operation, along rail surface, move forward and backward, between concrete slab sleeper, push shovel, make institute's concreting meet railway roadbed design elevation position, complete absolute altitude and control operation.
