Technical Field

The invention belongs to the technical field of ballastless track construction, and particularly relates to a double-block ballastless track fine tuning machine and a method.

Background

Among the high-speed railway construction processes, ballastless track laying is one of the most important links. The Ballastless track (Ballastless track) is a track structure which adopts an integral foundation (i.e. an integral track bed) of concrete, asphalt mixture and the like to replace a loose gravel track bed, and is also called a Ballastless track. The integral ballast bed of the ballastless track, also referred to as a track bed slab, is typically a cast-in-place reinforced concrete structure. The track bed board is an installation foundation of a steel rail (namely a track), the track bed board needs to be poured before the formal operation track is paved, and the pouring precision of the track bed board is important for the precision of paving the track of the future track.

At present, when a track bed slab of a double-block ballastless track is constructed, a track panel method is adopted for construction, the track panel refers to a track frame which is formed by assembling two steel rails and a rail lower component by fasteners, the rail lower component is mainly a sleeper, so that the two steel rails and the rail lower component (mainly the sleeper) are connected by a connecting piece (namely, the fastener, also called as a track panel fastener) to form the track panel, the track panel comprises two steel rails, the rail lower component arranged below the two steel rails and the fasteners which connect the two steel rails and the rail lower component into a whole, and each steel rail and the rail lower component positioned below the steel rail are connected by the fasteners to form a track panel frame. The track panel method is a ballastless track construction method which adopts a hoisting and laying tool to hoist the track panel in place and pour the concrete of the track bed plate into the forming template after fine adjustment is qualified. When the track bed slab of the double-block ballastless track is constructed by adopting a track panel method, the prefabricated sleeper is accurately positioned to the corresponding position below the track by hoisting and finely adjusting the track panel, and then cement concrete is poured, so that the finely adjusted positioning of the track panel before pouring becomes a key control process. During actual construction, the requirement on the fine adjustment precision of the track panel is high, and errors (including elevation errors and central line errors) of the spatial positions of sleepers are required to be less than +/-0.5 mm before pouring.

In the past, the track panel is precisely adjusted by cooperation of a measurer and a worker. The surveyor uses the total station and the rail inspection trolley to measure the position error of each sleeper on the track panel, and then orally transmits the error value to the worker, and the worker uses a wrench to screw the elevation screw and the central line screw on the track panel, so that the error is eliminated. In the actual construction process, the defects of the track panel fine adjustment construction method are obvious and mainly embodied in the following three aspects: firstly, the manpower is more: the fine adjustment construction needs 2 surveyors to operate the total station and the fine adjustment trolley, and simultaneously needs 4 to 6 workers to screw a wrench for adjustment, which is labor-consuming and time-consuming; secondly, the adjusting speed is slow: measuring by using a total station by 1 measurer, manually pushing a rail inspection trolley by another measurer, verbally transmitting the measurement data of 4 detection sections (12 measurement points in total) on the rail panel to a worker after obtaining a measurement result, manually twisting a wrench by the worker according to the heard data, and repeating the operation for 4-5 times to adjust the position of the rail panel, wherein the adjustment of one rail panel needs 15-25 minutes; thirdly, the adjustment precision is low: because of the construction links such as manual speaking, manual wrench screwing and the like, the situations of wrong listening, reverse direction screwing by workers, wrong wrench rotation angle or number of turns and the like can not be avoided, so the operation precision is low, and the precision completely depends on the proficiency of the workers, thereby causing poor track panel adjustment precision. Due to the defects and problems of the three aspects, the problems of long construction period, high construction cost, low construction quality and the like of ballastless track construction are caused, and related railway construction units are troubled for many years. Therefore, an apparatus with high automation degree, high construction efficiency and construction quality independent of operators is urgently needed at present, and the ballastless track panel can be simply, conveniently, quickly and accurately adjusted.

Therefore, a reliable closed-loop control system is formed to accurately adjust the elevations of the center line and the left side and the right side of the current accurate adjustment position of the track panel to be adjusted.

In addition, in order to control the fine tuning machine easily and further improve the automation degree of the fine tuning machine, in step 201, in the process that the double-block type ballastless track fine tuning machine moves forward along the longitudinal extension direction of the ballastless track to be constructed, the frame position detection device 10 is in a detection state and detects the position of the underframe 1 in real time, and the detected information is synchronously transmitted to the main controller 13 and/or the upper monitoring terminal 9; the main controller 13 or the upper monitoring terminal 9 controls the double-block ballastless track fine tuning machine according to information detected by the frame position detection device 10 until the underframe 1 of the double-block ballastless track fine tuning machine is moved to a current fine tuning position, and the automatic positioning process of the double-block ballastless track fine tuning machine is completed.

In this embodiment, the constructed ballastless track includes two ballastless tracks in parallel, the two double-block ballastless track fine tuning machines are adopted to perform fine tuning on track panels of the two ballastless tracks in the constructed ballastless track respectively, the two double-block ballastless track fine tuning machines move forwards synchronously, and the two ballastless track fine tuning machines and the track panels are both accurate according to the method described in the first step to the second step. Therefore, the two double-block ballastless track fine tuning machines synchronously act, the automatic fine tuning process of the track panel of two parallel ballastless tracks (including ballastless tracks of an uplink line and ballastless tracks of a downlink line) can be synchronously completed, the use and the operation are very simple and convenient, the fine tuning effect is good, and the fine tuning process is easy to control.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
