Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a rapid adjustment and installation device for a vehicle section maintenance trench track and a construction method thereof. Background Art

[0002] With the rapid development of urban rail transit, the vehicle depot, as an important part of the rail transit system, undertakes important tasks such as vehicle inspection, maintenance and storage. As one of the key facilities for track inspection in the vehicle depot, the vehicle depot track inspection trench is built on the basis of the reinforced concrete of the inspection trench, and the rails are erected using the integral support method, thereby ensuring the fast and efficient inspection trench and the safety of railway construction and operation in the station yard. Its construction quality and efficiency directly affect the operational safety and maintenance cost of the vehicle depot.

[0003] The columns of the maintenance trench are the supporting foundation of the track, which are generally cast on site. However, due to the fact that the entire trench cannot be cast at the same time during track construction, it can only be cast one section at a time, which easily causes the linear unevenness of the front and rear sections of the track overlap. In order to improve construction efficiency and reduce costs, and solve the problems of long construction period, high difficulty, and low track accuracy in traditional maintenance trench construction methods, it is very important to find an efficient, accurate, and convenient vehicle depot maintenance trench track rapid adjustment installation device and its construction method. Summary of the invention

[0004] The object of the present invention is to provide a rapid adjustment and installation device for a vehicle depot maintenance trench track and a construction method thereof for solving the above-mentioned technical problems.

[0006] The longitudinal track support frame is arranged on the cushion block through the bottom of the longitudinal track support frame base, and is connected to the longitudinal adjustment screw. A clamping block is arranged on the upper part of the longitudinal adjustment screw, and a longitudinal track adjustment rod is arranged on the top. The transverse track adjustment positioning frame is fixed on the longitudinal adjustment screw through the clamping block.

[0007] A track positioning groove is arranged on the transverse track adjustment positioning frame, and the rail is located on the track positioning groove. Transverse track pushers are arranged on both sides of the track positioning groove. The transverse track pushers are connected to the spiral bevel gear through a transverse adjustment screw. A transverse track adjustment rod is arranged on the upper part of the spiral bevel gear.

[0008] The rails are fixed to the prefabricated hollow columns by fasteners, and the bottom of the prefabricated hollow columns is fixed to the maintenance trench foundation by cast-in-place concrete.

[0009] Furthermore, the longitudinal track support frame includes a longitudinal track support frame base, a longitudinal adjustment screw, a clamping block and a longitudinal track adjustment rod; an internal thread is provided on the upper part of the longitudinal track support frame base, and the longitudinal track adjustment rod is rotated to adjust the length of the longitudinal adjustment screw in the longitudinal track support frame base, thereby adjusting the height of the transverse track adjustment positioning frame fixed on the clamping block.

[0010] Furthermore, the transverse track adjustment and positioning frame includes a transverse track adjustment rod, a spiral bevel gear, a transverse adjustment screw, a transverse track pusher and a track positioning groove; the track positioning groove spacing is set according to the rail spacing; an internal thread is set in the transverse track pusher, and rotating the transverse track adjustment rod drives the spiral bevel gear and the transverse adjustment screw to rotate, thereby controlling the left and right lateral displacement of the transverse track pusher, and promoting the lateral position change of the rail in the track positioning groove.

[0011] The construction method of the vehicle depot maintenance trench track rapid adjustment and installation device provided by the present invention comprises the following steps:

[0012] S1. Construction preparation and base treatment: clean and repair the surface of the trench foundation, bring in raw materials, and have construction vehicles and equipment ready;

[0013] S2. Put the track quick adjustment installation device in place: according to the reference position measured by the total station, lay the pads, set up the transverse track adjustment positioning frame, install the longitudinal track support frame, and hoist the rails into the track positioning groove;

[0014] S3. Quickly adjust the track height: rotate the longitudinal track adjustment rod, adjust the length of the longitudinal adjustment screw in the base of the longitudinal track support frame, and position the transverse track adjustment positioning frame fixed on the block to the designed elevation position;

[0015] S4. Rapid adjustment of track horizontal position: Rotate the lateral track adjustment rod to drive the spiral bevel gear and the lateral adjustment screw to rotate, control the left and right lateral displacement of the lateral track pusher, and push the rail to the designed horizontal position in the track positioning groove;

[0016] S5. Installation of prefabricated hollow columns at the bottom of the rail: hoist the prefabricated hollow columns under the rails and fix them with fasteners;

[0017] S6. Cast-in-place concrete construction: connect and tie the steel bars in the maintenance trench foundation with the steel bars at the bottom of the prefabricated hollow columns, lay out the formwork, and pour concrete;

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. In order to further understand the content, features and functions of this invention, the following will be described in detail with reference to the accompanying drawings as follows:

[0031] Example 1

[0032] like Figure 1-Figure 3 As shown, the present invention provides a rapid adjustment and installation device for a vehicle depot maintenance trench track, comprising:

[0033] (1) Longitudinal track support frame

[0034] 1. Components

[0035] The longitudinal track support frame comprises a longitudinal track support frame base 1 , a longitudinal adjustment screw 3 , a clamping block 16 and a longitudinal track adjustment rod 4 .

[0036] An internal thread is arranged on the upper portion of the base 1 of the longitudinal track support frame.

[0037] 2. Working Principle

[0038] The longitudinal track support frame 2 is arranged on the cushion block 13 through the bottom of the longitudinal track support frame base 1. When the longitudinal track adjustment rod 4 is rotated, the length of the longitudinal adjustment screw 3 in the longitudinal track support frame base 1 can be adjusted. Since the transverse track adjustment positioning frame 9 is fixed to the longitudinal adjustment screw 3 through the clamping block 16, the height of the transverse track adjustment positioning frame 9 fixed on the clamping block 16 can be adjusted by adjusting the length of the longitudinal adjustment screw 3, thereby achieving the adjustment of the track height. The operation difficulties and height deviation problems caused by the deflection of the longitudinal track support frame are avoided, and the construction accuracy and efficiency are improved.

[0039] (II) Horizontal track adjustment positioning frame

[0040] 1. Components

[0041] The transverse track adjustment and positioning frame 9 includes a transverse track adjustment rod 7 , a spiral bevel gear 5 , a transverse adjustment screw 6 , a transverse track pusher 8 and a track positioning groove 10 .

[0042] The spacing between the track positioning grooves 10 is set according to the spacing between the rails 15 .

[0043] The transverse rail pusher 8 is provided with an internal thread.

[0044] 2. Working Principle

[0045] The rail 15 is located on the rail positioning groove 10. The rotation of the transverse rail adjustment rod 7 drives the spiral bevel gear 5 to rotate, and the spiral bevel gear 5 drives the transverse adjustment screw 6 to rotate. Since the transverse rail pusher 8 has an internal thread that cooperates with the transverse adjustment screw 6, the transverse rail pusher 8 is controlled to move horizontally to the left and right, pushing the rail 15 to change its horizontal position in the rail positioning groove 10. The traditional bolt adjustment is optimized to the rotation of the transmission rod, which reduces the use of tools, solves the operational difficulties caused by the small construction space, and further improves the construction efficiency and quality. At the same time, the rail positioning groove 10 is set according to the rail spacing, which realizes the initial and rapid positioning of the rail 15, reduces the difficulty of hoisting positioning, and improves the construction efficiency.

[0046] (III) Overall structure and connection relationship

[0047] The longitudinal track support frame 2 is set on the pad 13 through the bottom of the longitudinal track support frame base 1, and is connected to the longitudinal adjustment screw 3. A clamping block 16 is set on the upper part of the longitudinal adjustment screw 3, and a longitudinal track adjustment rod 4 is set on the top. The transverse track adjustment positioning frame 9 is fixed on the longitudinal adjustment screw 3 through the clamping block 16.

[0048] The rails 15 are fixed to the prefabricated hollow columns 11 by fasteners, and the bottom of the prefabricated hollow columns 11 is fixed to the maintenance trench foundation 14 by cast-in-place concrete 12 .

[0049] Example 2

[0050] Based on the same concept, Figure 4 As shown, the present invention provides a construction method for a rapid adjustment and installation device for a vehicle depot maintenance trench track, comprising the following steps:

[0051] S1. Construction preparation and base treatment:

[0052] Clean and inspect the surface of the trench foundation 14 to ensure that there is no debris, dust, etc. on the surface to provide good basic conditions for subsequent construction.

[0053] Raw materials such as prefabricated hollow columns 11, rails 15, and pads 13 are brought into the site and quality inspection is performed to ensure that the materials meet the design requirements.

[0054] Construction vehicles and equipment such as cranes and total stations are ready to ensure that the equipment can operate normally during the construction process and improve construction efficiency.

[0055] S2. Rail quick adjustment installation device is in place:

[0056] According to the benchmark position measured by the total station, the accurate position and elevation of the track are determined.

[0057] The pads 13 are laid to ensure that they are laid flat and firmly, thereby providing stable support for the longitudinal track support frame 2 .

[0058] Set up the transverse track adjustment positioning frame 9 and install it in a suitable position to ensure that its horizontality and verticality meet the requirements.

[0059] The longitudinal track support frame 2 is installed and firmly connected to the transverse track adjustment and positioning frame 9 via the clamping block 16 .

[0060] Finally, a crane is used to hoist the rail 15 into the rail positioning groove 10 , and attention is paid to safety during the hoisting process to prevent the rail 15 from being damaged by collision.

[0061] S3, quick adjustment of track height:

[0062] Rotate the longitudinal track adjustment rod 4 to adjust the length of the longitudinal adjustment screw 3 in the longitudinal track support frame base 1, and position the transverse track adjustment positioning frame 9 fixed on the block 16 to the designed elevation position. During the adjustment process, a level or other measuring tool can be used for real-time monitoring to ensure that the track height meets the design requirements and improve the track accuracy.

[0063] S4, quick adjustment of track horizontal position:

[0064] Rotating the transverse track adjustment rod 7 drives the spiral bevel gear 5 and the transverse adjustment screw 6 to rotate, controls the transverse track pusher 8 to move horizontally to the left and right, and pushes the rail 15 to the designed horizontal position in the track positioning groove 10. Similarly, during the adjustment process, a measuring tool such as a theodolite can be used for monitoring to ensure that the horizontality of the track meets the design and specification requirements.

[0065] S5. Installation of prefabricated hollow columns at the bottom of the rail:

[0066] The prefabricated hollow column 11 is hoisted below the rail 15, and the rail 15 is firmly fixed to the prefabricated hollow column 11 by fasteners. During the fixing process, it is ensured that the fasteners are correctly installed and tightly connected to ensure the stability of the track.

[0067] S6. Cast-in-place concrete construction:

[0068] The steel bars in the maintenance trench foundation 14 are connected and tied to the steel bars at the bottom of the prefabricated hollow column 11 to ensure that the steel bars are firmly connected and meet the design requirements for reinforcement ratio and steel bar spacing.

[0069] Lay out the template to ensure its flatness and verticality to prevent problems such as leakage during concrete pouring.

[0070] When pouring concrete 12, pay attention to vibrating and compacting it to ensure the quality of the concrete and avoid defects such as honeycombs and rough surfaces.

[0071] S7, track position verification:

[0072] The final position data of the rail 15 after concrete pouring is measured, and fine-tuned through the vehicle depot maintenance trench track quick adjustment installation device to meet the design and specification requirements and pass the acceptance. If the track position is found to be deviated, it can be fine-tuned again through the longitudinal track adjustment rod 4 and the transverse track adjustment rod 7 to ensure that the accuracy of the track meets the requirements before acceptance.

[0073] S8. Removal of the track quick adjustment installation device:

[0074] When the curing strength of cast-in-place concrete 12 reaches 75% of the design value, the track quick adjustment installation device can be removed. When removing, pay attention to the order, first remove the horizontal track adjustment positioning frame 9, then remove the longitudinal track support frame 2, etc. During the removal process, be careful to avoid damage to the constructed track and concrete structure.

[0075] Through the above specific embodiments, the vehicle depot maintenance trench track rapid adjustment and installation device and the construction method thereof of the present invention can efficiently and accurately complete the installation and construction of the track, solve many problems existing in traditional construction methods, improve the quality and efficiency of vehicle depot maintenance trench track construction, and provide a strong guarantee for the safe operation of urban rail transit.
