Description

Technical Field

[0001] This invention relates to the field of railways, and in particular to a long sleeper transfer device and its operation method after a railway turnout. Background Technology

[0002] Railway tracks are the tracks used by trains and other vehicles.

[0003] During railway turnout replacement work, replacing the entire turnout assembly is quite difficult. Therefore, it is necessary to disassemble the turnout, transport it in sections, and install it separately. After disassembly, the turnout can be divided into the front section, the frog section, and the rear sleeper section. Specialized railway transfer devices already exist for the front and frog sections, allowing for whole-section transport without exceeding railway locomotive clearance limits. However, since most of the rear sleepers are over 4 meters long, transporting the entire assembly would exceed locomotive and rolling stock clearance limits. Therefore, a railway turnout rear sleeper transfer device needs to be developed. This device can transfer all materials of the rear sleepers, meeting locomotive and rolling stock clearance requirements during transport. Upon arrival at the construction site, with manual assistance, all materials can be assembled quickly and then lifted and transported to the designated location by specialized equipment.

There is a pull plate guide groove on each side. A turnout sleeper seat 3 is installed on each second slewing bearing 11. A rail protection baffle 2 is set at each end of the main platform 8.

[0061] The turnout sleeper seat 3 is constructed from welded steel plates, with side panels on three sides and one side open. Under the action of the second slewing bearing 11 at the bottom, the turnout sleeper seat 3 can rotate around its center. A pair of support wheels 17 are installed on each side of the bottom of the turnout sleeper seat 3, with the paths of the two pairs of support wheels 17 lying on the same circumference.

[0062] The pull plate is driven by the rotary cylinder 9, which can realize the linkage of fifteen turnout sleeper seats 3. The turnout sleeper seat 3 is equipped with a lock fixing seat 22 for fixing the rail lock and the turnout sleeper lock 6.

[0063] The device is equipped with two sliding trolleys for placing the rails. The sliding rails 26 of the sliding trolleys can be bolted to any turnout sleeper seat 3 to meet the placement requirements of rails of different lengths. The sliding trolleys are equipped with jacks 31, which can be manually assisted to lift the rails and adjust their displacement along the direction of the sliding rails 26. Four rollers are set on the top seat plate of the sliding trolleys, allowing for fine adjustment of the rails in the longitudinal direction.

[0064] Two lifting devices 5 are installed in the middle of the main platform 8. The lifting devices 5 are bolted to the main platform 8 and consist of a hydraulic cylinder piston rod, an upper seat plate 35 of the lifting device, and a lower base 33 of the lifting device.

[0065] Compared with related technologies, the railway turnout long sleeper transfer device provided by the present invention has the following beneficial effects:

[0066] The overall equipment has high alignment accuracy, meeting the assembly accuracy requirements of turnout sleepers; it can handle the transfer and assembly of 4 rails with a maximum length of 10m and 13 turnout sleepers with a maximum length of 4.8m; the rails and turnout sleepers have reliable fixing devices during transportation; the profile of the working device meets the locomotive clearance requirements when in transportation mode.

[0067] Second Embodiment

[0068] Please refer to the following: Figure 8 and Figure 9 Based on the first embodiment of this application which provides a railway turnout long sleeper transfer device, the second embodiment of this application proposes another railway turnout long sleeper transfer device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0069] Specifically, the difference in the railway turnout long sleeper transfer device provided in the second embodiment of this application is that the working box 1 of the railway turnout long sleeper transfer device is provided with a fixing plate 36 inside, and the fixing plate 36 is provided with dividing lines 39 on all four sides.

[0070] Limiting bands 40 are fixedly installed around the front of the fixing plate 36.

[0071] The top of the work box 1 is provided with a box cover 37.

[0072] Both sides of the bottom of the box cover 37 are fixedly installed with latches 38.

[0073] The latch 38 secures its lid 37 to the top of the work box 1.

[0074] The fixing plate 36 can be folded along the dividing line 39 to form a rectangle that fits the internal space of the work box 1. Therefore, it can be placed inside the work box 1 and its state is restricted by the work box 1, so that it will not be spread out. The tool can be restricted on the fixing plate 36 by the limiting band 40.

[0075] The working principle of the railway turnout long sleeper transfer device provided by this invention is as follows:

[0076] When staff need to retrieve tools from inside the work box 1, they can open the latches 38 on both sides of the lid 37, thus eliminating the mutual restraint between the lid 37 and the work box 1, and allowing the lid 37 to be removed from the top of the work box 1.

[0077] Then, the fixing plate 36 can be manually pulled upward to remove it from the inside of the work box 1. Since the fixing plate 36 has dividing lines 39 around its inside, and the fixing plate 36 is in a folded state when it is inside the work box 1, the dividing lines 39 are in a mating state. When it is taken out, it loses the constraint of the work box 1 on the fixing plate 36, so the fixing plate 36 will unfold and lay flat on the ground, making it convenient for workers to take out the tools fixed by the limiting band 40.

[0078] Compared with related technologies, the railway turnout long sleeper transfer device provided by the present invention has the following beneficial effects:

[0079] The cooperation between the fixing plate 36, the box cover 37, the latch 38, the dividing line 39, the limiting band 40 and other structures allows the fixing plate 36 to be directly taken out from the inside of the work box 1 and unfolded when the tool is taken out. Therefore, it is convenient for the staff to take out the tool and the tool is neatly placed.

[0080] Third Embodiment

[0081] Please refer to the following: Figure 10 and Figure 11 Based on the railway turnout long sleeper transfer device provided in the first embodiment of this application, the third embodiment of this application proposes another railway turnout long sleeper transfer device. The third embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the separate implementation of the first embodiment.

[0082] Specifically, the difference in the railway turnout long sleeper transfer device provided in the third embodiment of this application is that, in the railway turnout long sleeper transfer device, a first magnetic plate 41 is provided on both sides of the fixing plate 36, a second magnetic plate 42 is provided on the outer side of the first magnetic plate 41, and the second magnetic plate 42 is fixedly connected to one outer end of the other fixing plate 36.

[0083] The first magnetic plate 41 and the second magnetic plate 42 are installed at the positions of the fold lines formed around the inside of the fixed plate 36, and the fold lines are not connected to each other.

[0084] The first magnetic plate 41 and the second magnetic plate 42 can be attached to each other to generate a magnetic attraction force, and the magnetic attraction force is strong enough to allow the fixing plate 36 to perform state restriction work after folding.

[0085] The working principle of the railway turnout long sleeper transfer device provided by this invention is as follows:

[0086] By folding the fixing plate 36, the folded parts are fixed in place by the magnetic attraction generated by the mutual adhesion between the first magnetic plate 41 and the second magnetic plate 42.

[0087] Compared with related technologies, the railway turnout long sleeper transfer device provided by the present invention has the following beneficial effects:

[0088] Through the mutual cooperation between the first magnetic plate 41, the second magnetic plate 42 and other structures, the fixed plate 36 can be in a stable state after being folded due to the mutual magnetic attraction between the first magnetic plate 41 and the second magnetic plate 42. Thus, it becomes a rectangle with an opening at the top, which is convenient for storage.

[0089] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
