Description

Technical Field

[0001] The invention belongs to the field of track precision construction, and in particular relates to an automatic fine-tuning system and method for an open bridge deck sleeper plate track structure on a steel truss. Background Art

[0002] The large-span steel truss structure is a commonly used structural type in modern railway bridges. It has the advantages of simple structure, convenient construction, strong bearing capacity, etc. It is widely used in the construction of conventional railways, high-speed railways and intercity railways. At present, the track structures commonly used for railway steel trusses at home and abroad include wooden sleeper open bridge deck track, ballasted track, synthetic resin sleeper track and sleeper plate structure track.

[0003] The open bridge deck track with wooden sleepers laid on traditional steel trusses is limited by the fact that wooden sleepers are easy to decay, mechanically wear and crack, and have a short structural life; the bridge deck with ballasted track is not easy to inspect and maintain and has a large deadweight; the cost of synthetic resin sleeper track is too high and is not suitable for large-scale laying applications; the sleeper plate structure track can improve the stability and durability of the track structure, reduce the workload of maintenance, and at the same time reduce the track construction height and the second phase constant load of the bridge, thereby reducing the cost of the main bridge project.

[0004] The sleeper plate structure track on steel truss beams includes rails, fasteners, sleeper plates, concrete cushion layers, high-strength connecting bolts, steel truss main longitudinal beams and other accessories. The sleeper plates are fixedly connected to the steel truss main longitudinal beams by high-strength bolts, and the concrete cushion layer is poured between the sleeper plates and the steel truss main longitudinal beams. Most of the existing track fine-tuning systems are designed for ballastless tracks and ballasted tracks, and there are few fine-tuning methods for the sleeper plate structure track on open bridge decks on steel trusses. For the sleeper plate structure track laid on steel trusses, after the concrete cushion layer is poured, the track structure fine-tuning mainly depends on the fastener system. This track fine-tuning method has a small adjustment amount, a large workload, and low efficiency. Summary of the invention

The track geometry state detector is used to collect the track structure geometry state and determine the sleeper plate to be adjusted. The adjustment amount information is transmitted to the jack control system through a communication system such as Bluetooth. The jack control system drives the three-way jack in real time to accurately adjust the geometry of the sleeper plate, thereby realizing the automatic fine-tuning of the sleeper plate track structure on the steel truss beam and greatly improving the working efficiency.

The track geometry detector has clear standards and is applicable to my country's track construction standards. It does not require independent development for the steel truss sleeper plate track structure, reducing the cost of purchasing additional equipment for overall track fine-tuning.

[0058] like Figure 2-5 As shown, a plurality of three-way jacks 7 are arranged between the sleeper plate 4 and the steel truss walkway 6. Under the synchronous actuation of the jack control system 8, the geometrical position of the sleeper plate 4 is finely adjusted in the vertical, longitudinal and transverse directions of the track.

[0059] like Figure 1-5 As shown, the connecting screw 9 is installed on the lifting sleeve 10 reserved on the side of the sleeper plate 4; the three-way jack 7 is connected to and adjusted by the connecting screw 9.

[0060] The three-way jack 7 faces one end of the steel truss girder walkway 6 and is fixed on the side of the steel truss girder walkway 6 close to the sleeper plate 4 .

[0061] The three-way jack 7 includes a support, which is connected to the connecting screw 9 by the support. Figure 6-7 As shown, the three-way jack 7 also includes a jack vertical support 13, a jack longitudinal support 14, and a jack transverse support 15 connected to the base, which are actuated individually or jointly by the jack control system 8.

[0062] The connection between the three-way jack 7 and the sleeper plate 4 and the steel truss girder walkway 6 is detachable, so as to facilitate disassembly and reuse.

[0063] The three-way jacks 7 are symmetrically arranged on both lateral sides of each sleeper plate 4 along the longitudinal line in the track. In this embodiment, four three-way jacks are symmetrically arranged on each sleeper plate.

[0064] The fine adjustment method of the automatic fine adjustment system of the open bridge deck sleeper plate track structure on the steel truss beam of the present invention comprises the following steps:

[0065] S1. Roughly lay the track structure including the sleeper plate 4, the fastener system 3 and the rail 2 according to the preset accuracy.

[0066] S2. Clean the lifting sleeves 10 reserved on both sides of the sleeper plate 4, and thread the connecting screw 9 along the lifting sleeve 10. The other end of the connecting screw 9 is fixedly mounted on the base of the three-way jack 7. The three-way jack 7 is equipped with a jack control system 8, which can receive signals through a Bluetooth device. The three-way jack 7 is installed on the side of the steel truss sidewalk 6, and does not occupy the working space of the track structure construction personnel.

[0067] The surface of the rail 2 is cleaned to make the rail surface clean and free of concrete blocks, gravel, oil stains, rust blocks and other objects that may affect the measurement accuracy of the track geometry detector 1.

[0068] S3. Before the fine-tuning operation begins, the fine-tuning starting mileage, the fine-tuning section sleeper plate number and its corresponding mileage information are set in the track geometry detector 1. The track geometry detector 1 determines the mileage and the corresponding sleeper plate number by recording the number of wheel rolling circles.

[0069] S4, installing the track geometry detector 1 at the starting point of the fine-tuning operation, and the staff pushes the track geometry detector 1 to collect the track structure geometry information;

[0070] S5. The track geometry detector 1 is installed at the starting point of the fine-tuning operation. The staff pushes the track geometry detector 1 to collect the geometry information of the track structure. The track geometry detector 1 simultaneously calculates the geometry deviation of the track structure.

[0071] S6. Send the adjustment amount corresponding to the sleeper plate 4 to the jack control system 8 via the Bluetooth system.

Figure 8-9 shown.

[0073] Preferably, in step S4, the track geometry detector 1 is used to measure the overall geometry of the track structure, and the installation deviations of the steel truss main longitudinal beam 5, the sleeper plate 4, the fastener system 3, and the rail 2 are completely collected;

[0074] In step S5, the amount of the track structure to be adjusted is calculated by comparing it with the standard data of the track structure geometry;

[0075] In step S6, the amount to be adjusted is transferred to the adjustment of the sleeper plate.

[0076] Preferably, the method further comprises the following steps:

[0077] S8. After the fine-tuning of the track structure in this fine-tuning section is completed, the sleeper plate 4 and the steel truss main longitudinal beam 5 are fixed with high-strength connecting bolts, and then a concrete cushion layer is poured between the sleeper plate 4 and the steel truss main longitudinal beam 5; after the concrete cushion layer is poured and stabilized, the three-way jack 7 and the jack control system 8 are removed to achieve the reuse of subsequent fine-tuning sections.

[0078] The connecting screw 9 is installed on the sleeper plate 4 using the reserved lifting sleeve 10, and the three-way jack 7 drives the sleeper plate 4 to adjust the geometric position through the connecting screw 9. The connecting screw 9 and the base of the three-way jack 7 are fastened and connected by the positioning bolts 16, and the structure is stable and easy to install and disassemble.

[0079] Each of the sleeper plates 4 is equipped with four groups of three-way jacks 7 and the jack control system 8, and two groups are symmetrically arranged on each side of the sleeper plate 4. Driven by the jack control system 8, the four groups of three-way jacks 7 synchronously adjust the vertical, horizontal and longitudinal positions of the sleeper plates 4; the adjustment of the longitudinal position of the sleeper plates 4 along the rails is handled by the front and rear two groups of three-way jack longitudinal supports 14. The three-way jack longitudinal support 14 located at one end of the sleeper plate 4 is responsible for adjusting the longitudinal movement of the sleeper plate 4 in one direction, and the three-way jack longitudinal support 14 located at the other end of the sleeper plate 4 is responsible for adjusting the longitudinal movement of the sleeper plate in another direction. The three-way jack vertical support 13 is responsible for adjusting the vertical position of the sleeper plate, and the three-way jack transverse support 15 is responsible for adjusting the transverse position of the sleeper plate. The four groups of three-way jacks 7 all act synchronously to avoid damage to the sleeper plate 4 due to inconsistent jack action.

[0080] After the above-mentioned automatic fine-tuning operation is completed, the sleeper plate 4 and the steel truss main longitudinal beam 5 are fixedly connected by high-strength connecting bolts 11 and high-strength connecting bolt holes 17, and the concrete cushion layer 12 is poured through the gap between the sleeper plate limiting holes 18 and the steel truss main longitudinal beam limiting parts. After the concrete cushion layer is poured and stabilized, the three-way jack 7 and the control system 8 can be removed to realize the reuse of the automatic fine-tuning equipment.

[0081] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
