Description

Technical Field

[0001] The invention belongs to the technical field of track construction, and in particular relates to an intelligent construction system for ballastless tracks in super-long tunnels on a plateau. Background Art

[0002] At present, the following problems exist in track slab construction: (1) During the pouring construction of ballastless track, conventional hoists are used to grab the lifting holes at the four corners of the track plate or the silo for lifting. It is necessary to manually hook the lifting holes one by one, which is cumbersome to operate. The lifting length cannot be guaranteed to be consistent, which leads to shaking during lifting. In addition, conventional hoists cannot adapt to the width of the track base plate. Therefore, the left and right position deviations are easy to occur during the movement of the hoist after lifting, resulting in deviations in the falling position of the track plate or the silo, affecting the construction progress; (2) For the maintenance of the poured concrete of the ballastless track, water is manually sprinkled as evenly as possible and then covered with a film for maintenance. The operation is complicated. The operation is cumbersome and requires the cooperation of multiple people, which increases labor costs. In addition, it cannot achieve the effect of constant temperature and humidity. The concrete curing conditions are poor and the curing effect is not good, which affects the quality of concrete and leaves safety hazards. (3) At present, the gripper assembly of the conventional track plate hoist is equipped with a measuring device for measuring and feedback position. Therefore, when the hoist lowers the track plate, during the process of adjusting the track plate laying position, the position of the gripper assembly can be adjusted according to the information fed back by the measuring device, thereby realizing fine adjustment of the track plate. However, due to the linkage of the left and right grippers, the left and right sides can only be adjusted synchronously during longitudinal adjustment, so that the four corners of the track plate cannot be individually and accurately adjusted, resulting in limited adjustment accuracy and low precision. Summary of the invention

[0003] The present invention aims to provide an intelligent construction system for ballastless track in super-long tunnels on the plateau, which has convenient and fast lifting without deviation, high track paving accuracy and good concrete curing effect, and solves the problems that the current conventional hoists need to manually hook the lifting holes one by one, which is cumbersome to operate, the lifting length cannot be guaranteed to be consistent during lifting, which leads to easy shaking, and the left and right position deviation is also easy to occur during the movement of the hoist after lifting. The concrete curing of the ballastless track is to manually sprinkle water as evenly as possible and then directly cover it with a film for curing, which has the problems of cumbersome operation, increased labor costs, poor curing effect, and the left and right grippers of the track plate hoist cannot individually and accurately adjust the four corners of the track plate.

[0004] To this end, the technical solution adopted by the present invention is: an intelligent construction system for ballastless track in a super-long tunnel on a plateau, including a slab laying and pouring construction crane, four track slab laying fine-tuning devices, a concrete pouring silo and a concrete maintenance folding shed. The slab laying and pouring construction crane is used to lift the track slab and lay it on the track base plate, or to lift the concrete pouring silo to pour concrete between the track slab and the track base plate. The slab laying and pouring construction crane includes a moving gantry, a pulling mechanism located on the upper part of the moving gantry, and a lifting and clamping mechanism connected to the pulling mechanism in upper and lower correspondences. The pulling mechanism includes a pulling main frame installed on the upper part of the corresponding moving gantry, a pulling hydraulic cylinder installed symmetrically and in parallel on the pulling main frame, and a left The right symmetrically arranged steel cable limit winding column and the four steel cables at the four corners of the lifting and clamping mechanism, one end of the steel cable is wound around the telescopic end of the pulling hydraulic cylinder, and the other end is passed around the corresponding steel cable limit winding column and then vertically downward to be connected with the corresponding lifting ears at the four corners of the lifting and clamping mechanism. When the pulling hydraulic cylinder is extended and retracted, the lifting and clamping mechanism is horizontally lifted and lowered by synchronously pulling the four steel cables; the track plate laying fine-tuning device is correspondingly installed at the four corners of the track plate to fine-tune the horizontal, vertical and vertical positions of the track plate. The track plate laying fine-tuning device includes a longitudinal adjustment component, a transverse adjustment component and a vertical adjustment component which are arranged in sequence from bottom to top; the concrete curing folding shed is used to perform constant temperature and humidity curing on the concrete poured between the track plate and the track base plate.

The two clamping connecting longitudinal rods are hinged to the two ends of the clamping hydraulic cylinder through a "V"-shaped cylinder connecting frame. When the two ends of the clamping hydraulic cylinder are synchronously extended and retracted outward, the angle of the "V"-shaped cylinder connecting frame increases or decreases, driving the two clamping connecting longitudinal rods to move closer or farther away, thereby causing the clamping seat to synchronously loosen outward or clamp inward, and automatically control the clamping and loosening. The operation is simple and quick, and the clamping is stable.

[0006] Further preferably, the mobile gantry includes telescopic columns located at four corners, pulling support frames overlapped on the upper parts of the telescopic columns at four corners, and a roller assembly installed at the bottom of the telescopic columns, the roller assembly includes a roller box, moving rollers located in the roller box, a driving motor that provides driving force for the moving rollers, and a guide limiting wheel located at the outside of the roller box and sliding along the side wall of the track base plate. The rollers are driven by the driving motor to move automatically, which is simple to operate, and the lateral limitation of the entire crane is achieved by the guide limiting wheel, which effectively avoids deviation during the movement of the crane.

[0007] The front side of the pulling support frame is equipped with a cable storage coil, and the rear side is equipped with a hydraulic station; the telescopic column adopts two sections of square columns with inner and outer sleeves, and the upper square column is equipped with a telescopic hydraulic cylinder, so as to realize the overall lifting of the pulling support frame and the avoidance of obstacles; the two telescopic columns located on the same left or right side are provided with slide brackets, and the lifting main frame is equipped with a telescopic offset adjustment part corresponding to the slide bracket, and the outer end of the telescopic offset adjustment part is equipped with a limiting roller that can slide along the slide groove in the slide groove bracket.

The steel cable longitudinal adjustment disk and the steel cable dividing disk both adopt upper and lower layers of wire drums, so as to respectively accommodate two steel cables. The structural design is reasonable to ensure the synchronous pulling of the four steel cables, thereby ensuring the horizontal lifting and lowering of the lifting clamping mechanism.

[0011] It is further preferred that the longitudinal adjustment component includes a longitudinal slide base, a longitudinal slider sliding along the longitudinal slide base, and a longitudinal driving member pushing the longitudinal slider to slide; the transverse adjustment component includes a transverse slide base installed on the longitudinal slider, a transverse slider sliding along the transverse slide base, and a transverse driving member pushing the transverse slider to slide; the vertical adjustment component includes a vertical slide base installed on the transverse slider, a vertical slider sliding vertically along the vertical slide base, and a vertical driving member driving the vertical slider to rise and fall; the vertical slider is provided with a mounting plate threadedly connected to the track plate on one side close to the track plate, so that it can be installed correspondingly at the four corners of the track plate.

[0012] The vertical slider of the vertical adjustment assembly is provided with a mounting plate threadedly connected to the track plate on the side close to the track plate. Since there is a 10cm concrete-filled gap between the track plate and the track base plate, the track plate is connected to the vertical slider, which can effectively ensure that the track plate does not directly contact the track base plate, and the installation positions of the adjustment components do not conflict with each other and are reasonably arranged.

[0013] It is further preferred that the longitudinal drive member, transverse drive member and vertical drive member all adopt screw motor reducers, and the selection is reasonable; the bottom surface of the longitudinal slide base is provided with a serrated anti-slip structure, and the front and rear ends are close to the bottom edges and are provided with bolt mounting seats connected to the rail base plate; the middle part of the longitudinal slide base is provided with an accommodation opening for the screw of the longitudinal drive member to pass longitudinally; the bottom of the longitudinal slide is installed on the screw nut of the longitudinal drive member to prevent floating, and the structural design is reasonable, thereby effectively avoiding the device from being pushed in the opposite direction during fine adjustment, thereby affecting the adjustment accuracy.

The foldable shed includes a plurality of groups of driven traveling gantries arranged in parallel front and back, an "X"-shaped connecting rod connecting adjacent driven traveling gantries, and a traction active traveling gantries driving the driven traveling gantries. The constant temperature and humidity curing mechanism includes a temperature and humidity sensor, a cooling and moisturizing pipeline, a heating and moisturizing pipeline, a water tank, and an electric heating steam generator.

Except for the adjacent traction active walking gantry, the bottoms of the other driven walking gantry are all provided with driven walking rollers. When the traction active walking gantry moves along the track base plate, several driven walking gantries are driven to move away from or closer to each other, thereby realizing the unfolding and folding of the foldable scaffolding.

[0018] A constant temperature and humidity maintenance mechanism is used to achieve temperature and humidity controlled concrete maintenance. The water tank temperature is adjusted and the cooling and moisturizing pipeline or the heating and moisturizing pipeline is selected for water spraying through the data transmitted by the temperature and humidity sensor. The temperature and humidity conditions in the maintenance shed are monitored in real time, and the need for heating or drinking is determined based on the measured temperature data to ensure that the temperature and humidity inside the tarpaulin are always maintained within the established maintenance standard range. The water spraying amount is flexibly adjusted to achieve constant temperature and humidity maintenance of the concrete, with good maintenance effects and reduced manpower and material costs.

[0019] The driving motor of the active traction gantry provides the walking power. When the active traction gantry moves along the track base plate, it can drive several driven gantry to move away from or close to each other, so as to realize the unfolding and folding of the foldable scaffolding. After unfolding, the ballastless track can be maintained. During the maintenance process, the distance between the support frames can be adjusted according to the needs of different working spaces, so that the entire device can adapt to working environments of various sizes. The driven gantry is connected by an "X"-shaped connecting rod. The distance between adjacent gantry is adjusted by changing the angle of the "X"-shaped connecting rod, and the structure is linked together.

[0027] Beneficial effects of the present invention:

[0028] (1) Compared with the current conventional hoisting equipment that needs to be manually hooked into the lifting holes one by one, this solution uses a crane specially used for ballastless track paving and pouring construction. The mobile gantry can move along the track base plate to ensure that the hoisting equipment will not be misaligned. The clamping hydraulic cylinders of the lifting clamping mechanism can be extended and retracted outward at both ends synchronously. Compared with the current hoisting equipment that cannot ensure the same lifting length during lifting, the pulling hydraulic cylinder of the pulling mechanism of this solution can be pulled by four steel cables synchronously to make the lifting clamping mechanism rise and fall horizontally, ensuring that the lifting level will not shake easily during lifting, and the structure is linked together.

[0029] (2) Compared with the current track plate hoist, the left and right grippers can only move synchronously along the track during longitudinal adjustment. This solution uses a fine-adjustment device installed at the four corners of the track plate. Through the longitudinal adjustment component, the lateral adjustment component and the vertical adjustment component, each corner of the track plate can be fine-tuned separately in the horizontal, vertical and vertical directions. This effectively avoids the situation where the left and right sides need to be adjusted synchronously, resulting in low fine-tuning. It has high fine-adjustment accuracy, novel conception and ingenious design.

[0030] (3) Compared with the current method of curing the cast concrete of ballastless track by manually sprinkling water as evenly as possible and then directly covering it with a film, this solution uses a concrete curing folding shed to directly unfold and cover the cast concrete on the track base plate. It can be used to ensure the early and mid-term strength of the ballastless track concrete construction and provide a constant temperature and humidity curing environment.

[0031] In summary, the present invention has the advantages of simple and quick operation, stable lifting, high precision of fine adjustment, novel conception, and constant temperature and humidity curing of concrete. BRIEF DESCRIPTION OF THE DRAWINGS
