Description

Technical Field

[0001] The invention relates to the technical field of railway engineering machinery, and in particular to a novel rail transport flat car. Background Art

[0002] At present, with the rapid development of urban infrastructure, more and more cities have begun to vigorously build subway rail transit. Due to the limitation of shield size, the construction space in the subway is small. During the subway construction process, subway track laying is the most important process and also the part with the largest workload. Often, the efficiency of subway track laying directly affects the time node of subway opening, so track transport flat cars will be used to transport rails to increase the speed of rail laying.

The rail transport flat car for subway construction shown in the present invention can carry rails and sleepers on the track through the flat car, and transport a large number of sleepers and rails to the construction site, thereby increasing the handling capacity, reducing the labor intensity, avoiding multiple handling, improving work efficiency, and improving the practicality of the equipment.

[0031] Two bogies 3 are respectively arranged at two ends of the bottom of the frame 9 .

[0032] The rail storage platform 12 is disposed between the rail transverse movement device 11 and the rail conveying device 10 .

[0033] Handrails 2 are fixedly installed at both ends of the top of the frame 9, and vehicle ladders 1 are fixedly installed at both ends of the two sides of the frame 9.

[0034] A battery 4, an air brake system 5, a tool box 6 and a hand brake 7 are respectively arranged at the bottom of the frame 9. The air brake system 5 is arranged on the side of the battery 4, the tool box 6 is arranged on the side of the air brake system 5, and the hand brake 7 is arranged on the side of the tool box 6.

[0035] The ladder 1 is used to facilitate workers to get on and off the flat car; the railing 2 is used to ensure the safety of workers when the vehicle is in operation; two bogies 3 are used for vehicle running and steering; the battery 4 is used to power the electrical equipment of the whole vehicle; the tool box 6 can store tools used for whole vehicle operation and maintenance; the air brake system 5 ensures the braking and relief of the vehicle when it is in operation; the hand brake 7 is used for parking the vehicle when it is parked for a long time or on a slope to prevent the vehicle from slipping; the frame 9 is used to provide a reference and space, as the main body of the vehicle, to carry other devices; two sets of hook buffer devices 8 are used for flat cars to be connected to each other or to other vehicles for marshaling operations; two sets of rail storage platforms 12 are used to store rails; two sets of rail conveying devices 10 can convey rails longitudinally and prevent the rails from tipping over during transportation; two sets of rail transverse movement devices 11 can lift and lower rails, adjust the height of rails, and move rails laterally to place them on the rail storage platform 12 or the rail conveying device 10.

[0036] The working principle of a novel rail transport flat car provided by the present invention is as follows:

[0037] When in use, several vehicle frames 9 are connected by hook buffer devices 8 to form a rail transport vehicle capable of storing rails of required length, and the rail transverse shifting device 11 is moved transversely to the middle position; when loading rails, the rails are transported to the designated position by the rail conveying device 10, and then dropped onto the rail transverse shifting device 11; the rails are sequentially dropped onto the rail storage platform 12 through the transverse movement of the rail transverse shifting device 11; the rail transport vehicle marshaling and the traction vehicle marshaling are combined to transfer the rails to the designated operation area;

[0038] When unloading the rails, the rail transverse movement device 11 moves horizontally to push the rails stored on the rail storage platform 12 to the middle position in sequence, lifts the rails onto the rail conveying device 10, and longitudinally transports the rails away from the rail transport vehicle; the rail conveying device 10 can adjust the height of the rails to keep it consistent with the operating height of other vehicles (rail unloading vehicle, rail collecting vehicle), so as to cooperate in completing the rail unloading and rail collecting operations.

[0039] Compared with the related art, the novel rail transport flat car provided by the present invention has the following beneficial effects:

[0040] Through the cooperation of the frame 9 and the hook buffer device 8, when in use, the hook buffer device 8 is connected to other vehicles and can be freely grouped and coordinated with other vehicles, so that the rail transport flat car can not only store rails, but also cooperate with other vehicles to complete rail unloading and rail collection operations; and the overall stable driving of the rails is achieved through the rail transverse shifting device 11 and the rail conveying device 10, and the transfer process is fully automated with a high degree of automation. The overall position of the rails can be changed without stress, which saves space while protecting the quality of the rails. It is suitable for work in construction environments with narrow spaces such as subways.

[0041] Second embodiment

[0042] Please refer to Figure 3 , Figure 4 and Figure 5 Based on the novel rail transport flat car provided by the first embodiment of the present application, the second embodiment of the present application proposes another novel rail transport flat car. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0043] Specifically, the difference of the new type of rail transport flat car provided in the second embodiment of the present application is that, in a new type of rail transport flat car, a plurality of magnetic suction components 13 are arranged on the top of the rail storage platform 12, and the plurality of magnetic suction components 13 include a fixed frame 131, a sliding rod 132, a spring 133, a connecting frame 134, a press switch 135 and an electromagnet 136, the electromagnet 36 is slidably connected to the inner side surface of the fixed frame 131, the connecting frame 134 is fixedly installed at the bottom of the electromagnet 136, the sliding rod 132 is slidably connected to the inside of the connecting frame 134, and the bottom of the sliding rod 132 is fixedly installed at the bottom of the inner side surface of the fixed frame 131, the spring 133 is sleeved on the outer side surface of the sliding rod 132, and the press switch 135 is fixedly installed at the bottom of the inner side surface of the fixed frame 131.

[0044] An extension rod 14 is fixedly installed at the bottom of the fixing frame 131 , and a fixing rod 15 is slidably connected to the outer side of the extension rod 14 . The bottom of the fixing rod 15 is fixedly installed on the top of the rail storage platform 12 .

[0045] A locking screw 16 is connected to the inner thread of the front side of the fixing rod 15 , and one end of the locking screw 16 abuts against the side surface of the extension rod 14 .

[0046] The working principle of a novel rail transport flat car provided by the present invention is as follows:

[0047] When in use, the user places the rail on the rail storage platform 12, and the bottom of the rail presses the electromagnet 136, so that the electromagnet 136 drives the connecting frame 134 to move downward, so that the bottom of the connecting frame 134 presses on the top of the pressing switch 135, and the electromagnet 136 can be activated by pressing the switch 135, so that the electromagnet 136 is energized to generate magnetic force, so that the rail is magnetically limited by the electromagnet 136;

[0048] When the rail needs to be removed, the staff lifts the rail through the rail transverse movement device 11. At this time, the spring 133 pushes the connecting frame 134 to move upward, so that the bottom of the connecting frame 134 is away from the pressing switch 135, so that the electromagnet 136 stops working and cancels the magnetic attraction of the rail.

[0049] Compared with the related art, the novel rail transport flat car provided by the present invention has the following beneficial effects:

[0050] By placing the rail on top of the electromagnet 136, the fixed magnet 136 can be energized to limit the rail, thereby preventing the rail from moving when the transport vehicle starts or brakes.
