Description

It is an important task that railway workers need to face during the skylight time operation.

[0003] Ballast track line handling involves the longitudinal transportation of steel rails, that is, transporting materials through the movement of the trolley on the above-mentioned track. However, when transporting materials between adjacent tracks, it can only be transported to the trolley on the adjacent track (i.e., horizontally crossing) through manual or mechanical means (such as a crane), and then transported to the area to be repaired or the area to be placed by the trolley on the adjacent track.

[0004] Therefore, a large amount of time is consumed when handling the device, and the efficiency is low. However, due to the limited skylight time for operation, when the workload is large, horizontal track crossing transportation becomes a major problem in railway operations.

[0025] The beneficial effects of the present utility model are as follows:

[0026] (1) When the present utility model mainly relies on four telescopic support legs for lateral transportation of lines, they can extend from the placement cavity of the vehicle body. When the items need to be transported laterally (i.e., transported from one track to an adjacent track), through the expansion and contraction of the left and right groups of telescopic support legs and the change of the bending angle between the frame and the telescopic support, the whole vehicle body can be laterally translated, playing the role of a conveyor belt. Moreover, the telescopic support restricts the device components during the lateral transportation of the vehicle body. Therefore, compared with the existing technology of only longitudinally transporting the trolley on the track, the transportation space is expanded, time is saved during transportation, and the efficiency is high, and the cross-track operation can be completed within the railway overhead time;

[0028] (3) By using the displacement sensor and the telescopic arm, when the present device is longitudinally transported on the track and encounters a change in the rail spacing at the turnout, the required adjustment distance can be measured, and the distance between the wheels can be controlled through the adjustable bearing to ensure that the device operates more smoothly and safely during operation. In addition, two displacement sensors are set to monitor the rail spacing in real time for a sensitive response; the telescopic arm is automatically adjusted under the drive of the third electric push rod, and the spacing is changed according to the information of the displacement sensor, so as to prevent derailment of the device due to an increase in the gauge when changing tracks at the turnout position and cause a safety accident;

[0029] (4) The telescopic support in the present utility model can also realize the up and down displacement of the device and make corresponding responses according to different situations; at the same time, its telescopic property ensures the flexibility and convenience of the device operation.

Specific embodiments

[0036] In order to make it easy to understand the technical means, creative features, achieved purposes and effects of the present utility model, the present utility model will be further described below with reference to specific drawings.

[0037] As Figures 1-5 shown, a handling device for ballasted track lines includes a cuboid vehicle body 1, the vehicle body 1 is arranged on a ballasted track, and a ballasted track parallel to it is arranged near the track. Telescopic support legs 2 are symmetrically installed on the side walls of the vehicle body 1 (specifically, two pairs of telescopic support legs 2 are arranged on the side walls of the vehicle body 1, and the two pairs of telescopic support legs 2 are symmetrically distributed). A telescopic support 21 is bendably arranged on the telescopic support legs 2. By alternately telescoping and moving the telescopic support legs 2 symmetrically arranged on the vehicle body 1 along the direction from one ballasted track to a ballasted track adjacent to it and parallel to it and by changing the bending angle of the telescopic support 21, the telescopic support 21 is retracted into the telescopic support legs 2, the vehicle body 1 is moved away from the original track and transported to an adjacent track;

[0038] Each telescopic support leg 2 consists of a telescopic robotic arm 22 with a multi-section telescopic structure, and one end of each telescopic support 21 is rotatably sleeved on the telescopic robotic arm 22.

[0039] Each multi - section telescopic structure includes a number of mutually sleeved frames 221. One of the frames 221 is fixed on the side wall of the vehicle body 1. The frame at the other end of the multi - section telescopic structure is rotatably sleeved with the telescopic support 21. The bend is at the connection between the frame 221 and the telescopic support 21. A first electric push rod 12 is hingedly installed on the frame 221 connected to the side wall of the vehicle body. The output end of the first electric push rod 12 is successively sleeved on other frames 221. The elongation or shortening of the movable end of the first push rod 12 drives the relative positions of all the frames 221 to change, thereby driving the telescoping of the multi - section telescopic structure. And the end of the movable end of the first electric push rod 12 is rotatably sleeved on the telescopic support 21. The telescopic support 21 is composed of a support frame 211 and a support leg 212. The support frame 211 is rotatably sleeved on the frame 221. The bend is at the connection between the support frame 211 and the frame 221. The end of the movable end of the first electric push rod 12 is rotatably sleeved on the support frame 211. By driving the first electric push rod 12, the elongation or shortening of the output end of the first electric push rod 12 enables the support frame 211 to slide and then rotate or rotate and then slide on the frame 221 at the end of the multi - section telescopic structure. The support leg 212 is slidably sleeved on the support frame 211. A second electric push rod 7 is rotatably sleeved on the support frame 211. The output end of the second electric push rod 7 is connected to the support leg 212. By driving the second electric push rod 7, the support leg 212 can be contracted or extended relative to the support frame 211;

[0040] A base frame 13 is installed at the bottom of the vehicle body 1. A spring 8 is also connected between the base frame 13 and the vehicle body 1, aiming to reduce the occurrence of tool dropping caused by track unevenness or vibration generated during the transportation of large objects. Four telescopic arms 14 are installed on the base frame 13. One end of the telescopic arm 14 is sleeved with a wheel 3.

[0041] Each telescopic arm 14 is composed of a fixed column 143 and several collars 141. The fixed column 143 is fixedly installed on the base frame 13 and is perpendicular to the bottom surface of the base frame 13. Several collars 141 are slidably sleeved in sequence, and all the collars 141 are jointly sleeved on the fixed column 143. A plurality of third electric push rods 142 are respectively installed along the height direction of the fixed column 143, and the output end of each third electric push rod 142 is connected to the collar 141. A motor 6 is installed on one of the collars 141 in each telescopic arm 14, and the output end of the motor 6 is connected to the shaft where the wheel 3 is located. Through the expansion and contraction of the third push rod 142, the position of the collar 141 relative to the fixed column 143 is changed, and the position between the collar 141 and the connected collar 141 is changed, ultimately making the wheel 3 contact or separate from the track. Two displacement sensors 9 are installed on the base frame 13, and the sensing ends of the two displacement sensors 9 correspond to a pair of tracks, which are used to measure the distance between the two tracks. A storage battery 10 is also installed on the vehicle frame 6, and a lighting lamp 5 is installed on one side wall of the vehicle body 1. The storage battery 10 is electrically connected to the lighting lamp 5, the displacement sensor 9, the first electric push rod 12, the second electric push rod 7, the third electric push rod 142, and the motor 6, and is used to supply power to the lighting lamp 5, the displacement sensor 9, the first electric push rod 12, the second electric push rod 7, the third electric push rod 142, and the motor 6 respectively to make them work normally. A placement cavity 11 corresponding to the telescopic support leg 2 is also provided at the bottom of the vehicle body 1. Through the placement cavity 11, the telescopic support leg 2 can be accommodated therein after contraction, and can be fixed by means such as but not limited to straps (for example, a positioning column is provided in the placement cavity 11, a strap is wound around the telescopic support leg 2, and then the two ends of the strap are fixed in the placement cavity 11 in the way of tying shoelaces).

[0042] It should be noted that a gasket is connected to the bottom of the support leg 212. Due to the existence of ballast on the ballasted track, the gasket can better ensure the safety of lateral handling of the line.

[0043] The working principle of the present utility model is as follows:

[0044] I. First, before the lateral handling of the line, the two telescopic robotic arms 22 on one side are in a contracted state, and only the second electric push rod 7 is driven to push the telescopic support 21 to fully extend it; on the other side, the first electric push rod 12 is driven to push the telescopic robotic arm 22 to fully extend it, and at the same time, the second electric push rod 7 is driven to push the telescopic support 21 to fully extend it; at this time, the four telescopic supports 21 fully support the vehicle body 1 and are separated from the rail.

[0045] II. Secondly, for the lateral handling of the line, the telescopic robotic arm 22 in the contracted state is extended under the drive of the first electric push rod 12, and at the same time, the telescopic robotic arm 22 in the extended state is contracted under the control of the first electric push rod 12.

[0046] III Finally, the four telescopic supports 21 contract under the control of the second electric push rod 7, causing the vehicle body 1 to descend uniformly onto the rail (the rail adjacent to the rail in Step I), and at the same time, the four telescopic robotic arms 22 contract into the vehicle body 1 under the drive of the first electric push rod 12. Thus, the lateral transportation of the line is completed.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
