Description

Technical Field

[0001] The utility model relates to a trolley for railway construction, in particular to a rotary sliding trolley for railway construction which is suitable for T-beams and rail tracks. Background Art

[0002] Railway construction in mountainous areas with slow design speeds often involves numerous small curves, creating a complex working environment with numerous interfering factors. This requires the rotation and sliding of T-beams and track panels. Feeding beams through small curves on the first and second carriages of the PJ165 bridge-erecting machine has long been a major challenge for this machine, especially during construction on curves with a small radius of 400 meters. Because the PJ165's original driven carriage lacks a rotation and sliding function, this presents construction difficulties during the 400-meter curve. Failure to properly handle the replacement of beam segments and track panels between the first and second carriages could result in the beam segments or track panels tipping over during transport. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and to provide a rotating sliding trolley for railway construction, which can rotate and slide autonomously during operation, thereby ensuring the smooth handover of beams or rails and improving work efficiency.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A rotary sliding trolley for railway construction includes a fixed frame installed on the vehicle body, an aviation lubrication plate fixed on the fixed frame, a core disc cover plate placed on the upper part of the aviation lubrication plate, and a downwardly extending protrusion provided in the middle part of the lower surface of the core disc cover plate. The protrusion can freely pass through the gap of the aviation lubrication plate and be movably stuck in the middle slide of the fixed frame, and can enable the protrusion of the core disc cover plate to freely rotate and slide in the middle slide of the fixed frame.

[0006] The fixing frame includes two parallel longitudinal supports and a transverse support connected in parallel to the two longitudinal supports. There is a gap between the two transverse supports, and the gap serves as a middle slideway of the fixing frame.

[0007] The end of the longitudinal support is provided with a pin hole, and the fixing frame is connected to the vehicle body via a pin shaft passing through the pin hole.

[0008] The fixing frame is also provided with a plurality of screw holes.

[0009] There are two aviation lubrication plates, which match the lateral supports.

[0010] The aviation lubricating plate is provided with a plurality of screw holes corresponding to the screw holes on the fixing frame, and the aviation lubricating plate is fixed to the fixing frame by countersunk hexagon socket screws passing through the screw holes.

[0011] The left and right ends of the upper surface of the core plate cover are respectively provided with longitudinal baffles.

[0012] A reinforcing rib plate fixed on the core plate cover is provided on the outer side of the longitudinal baffle.

[0013] A vertical through hole is formed at the rear end of the vehicle body, and a fixing seat is installed in the vertical through hole.

[0014] The car body in the present invention adopts the original car body, that is, the car body of the No. 1 and No. 2 cars of the PJ165 bridge crane remains unchanged. It mainly targets the problems in the background technology and adds the above-mentioned technical features of the present invention, so that the load-bearing objects on the upper part of the core disk cover plate of the trolley can rotate and slide with the core disk cover plate.

[0015] When the present invention is applied, two trolleys in front and behind are used to transport beam pieces or rail rows, that is, the front trolley is the active trolley (car No. 1) and the rear trolley is the driven trolley (car No. 2). Both trolleys are set on the track. The forward movement of the active rotating and sliding trolley of car No. 1 drives the movement of the driven rotating and sliding trolley of car No. 2. In order to ensure the stability of the beam piece or rail row, the No. 1 and No. 2 rotating and sliding trolleys will overcome the friction of the aviation lubrication plate to realize rotation and sliding during operation, and realize rotation within the track under the influence of the middle protrusion (pin shaft) of the core plate cover.

[0016] This utility model utilizes a driving vehicle to drive the driven vehicle. To ensure the smooth operation of the beams or rails, the autonomously rotating and sliding trolley can complete 360-degree rotation and lateral sliding, ensuring the safe and reliable transportation of the load. The main steel structure is made of 460C, which has a strong load-bearing capacity.

[0017] The utility model can also be installed in the vertical through hole of the vehicle body through the fixing seat to fix the trolley on the ground, and then cooperate with the external jack to push the core plate cover to realize the sliding movement of transporting beam pieces or rail rows.

[0027] like Figures 1-6 As shown, the rotating sliding trolley for railway construction includes a fixed frame 2 mounted on a vehicle body 1. The fixed frame 2 comprises two parallel longitudinal supports 7 and transverse supports 8 connected in parallel to the two longitudinal supports. A gap is formed between the two transverse supports 8, which serves as the intermediate slideway 6 of the fixed frame 2. Pin holes 9 are defined at the ends of the longitudinal supports 7. The fixed frame 2 is connected to the vehicle body 1 via a pin extending through the pin holes 9. The fixed frame 2 is also provided with multiple screw holes.

[0028] Two aviation lubrication plates 3 are fixed to the mounting bracket 2, matching the transverse supports 8. The aviation lubrication plates 3 are provided with multiple screw holes 10 corresponding to the screw holes on the mounting bracket 2. The aviation lubrication plates 3 are fixed to the mounting bracket 2 using countersunk hexagon socket head screws 11 passing through the screw holes 10.

[0029] A core plate cover plate 4 is placed on top of the aviation lubrication plate 3. A downwardly extending protrusion 5 is provided in the middle portion of the lower surface of the core plate cover plate 4. The protrusion 5 can freely pass through the gap of the aviation lubrication plate 3 and be movably stuck in the middle slide 6 of the fixed frame, and can enable the protrusion 5 of the core plate cover plate 4 to freely rotate and slide in the middle slide 6 of the fixed frame. Longitudinal baffles 12 are respectively provided on the left and right ends of the upper surface of the core plate cover plate 4. A reinforcing rib plate 13 fixed to the core plate cover plate 4 is provided on the outer side of the longitudinal baffle 12. A vertical through hole 14 is opened at the rear end of the vehicle body 1, and a fixing seat is installed in the vertical through hole 14.

[0030] The car body 1 in the present invention adopts the original car body, that is, the car body of the first and second cars of the PJ165 bridge crane remains unchanged. It mainly targets the problems in the background technology and adds the above-mentioned technical features of the present invention, so that the load-bearing material on the upper part of the trolley core plate cover plate 4 can rotate and slide with the core plate cover plate 4.

[0031] This utility model uses two trolleys, one in front and one behind, to transport beams or rails. The front trolley (cart 1) is the active trolley, while the rear trolley (cart 2) is the passive trolley. Both trolleys are mounted on tracks. Cart 1 actively rotates and slides the active trolley, driving the passive trolley (cart 2) forward. To ensure the stability of the beams or rails, trolleys 1 and 2 rotate and slide during operation, overcoming the friction of the aviation lubrication plate. They rotate within the track under the influence of the central protrusion (pin) of the core plate cover. This utility model utilizes the active trolley as the driving force, while the passive trolley, capable of autonomous rotation and sliding, ensures the smooth operation of the beams or rails. It can rotate 360 degrees and slide laterally, ensuring safe and reliable transport. The main steel structure is machined from 460C steel, providing a strong load-bearing capacity.

[0032] The utility model can also be installed in the vertical through hole of the vehicle body through the fixing seat to fix the trolley on the ground, and then cooperate with the external jack to push the core plate cover to realize the sliding movement of transporting beam pieces or rail rows.
