Description

Technical Field

[0001] The utility model belongs to the technical field of railway maintenance, and in particular relates to a railway bottom breaking and screening supporting device. Background Art

[0002] Railway bottom cleaning and screening is to hollow out the trackbed under the sleepers and clean and backfill the ballast when the railway subgrade disease or trackbed compaction disease needs to be repaired.

[0003] In the manual construction of railway bottom cleaning, the rails and sleepers can be removed, and then the ballast bottom cleaning can be carried out. However, the most convenient way is to support the sleepers at intervals to form a suspended rail frame for easy construction. However, the existing support method is to keep a part of the ballast under the sleepers without removing them, or to use wooden blocks for support.

[0004] The technical problems of using wooden blocks for support at present:

[0005] The method of using wooden blocks to support sleepers, firstly, requires a large number of wooden blocks to be prepared, secondly, the thickness of the roadbed supported by the wooden blocks is not easy to adjust, which is time-consuming and inefficient. The time to complete the task within the limited construction window is relatively tight; thirdly, the wooden blocks occupy a large area and are not convenient to withdraw. If it is necessary to lay civil cloth and other roadbed disease prevention measures after breaking the bottom and screening, the area occupied by the wooden blocks is not easy to lay and needs to be patched, which greatly reduces the effect of disease control. Utility Model Content

[0006] In view of this, the utility model provides a railway bottom breaking and screening support device to solve the problems of the existing method of using wooden blocks to support sleepers, which is material consuming, difficult to adjust, and occupies a large area.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A railway bottom breaking and screening support device comprises a telescopic structure, wherein the top of the telescopic structure contacts the bottom of a sleeper, and the bottom of the telescopic structure contacts the ground; an expansion member is provided on the bottom side wall of the telescopic structure, and one end of the expansion member is hinged to the side wall of the telescopic structure; there are a plurality of expansion members, and the plurality of expansion members are arranged at intervals along the circumference of the telescopic structure.

[0009] In this technical solution, it should be noted that the telescopic structure in this solution can be a structure with variable length of equal length of a hydraulic cylinder, a jack and a cylinder. The telescopic structure can support sleepers of different heights. Secondly, in this solution, an expansion component is provided. When the expansion component is rotated and unfolded, the coverage of the telescopic structure on the ground is increased, so that the telescopic structure basically will not tip over due to the shift of the center of gravity, so as to ensure the normal use and safety of the telescopic structure. In this solution, when it is necessary to break the bottom and screen the railway, the hollowing needs to support the bottom of the sleeper, and the other sleepers remain supported to ensure the stability of the track frame. After that, the ground at the hollowing position is cleaned and leveled, the telescopic structure is placed on the ground, and the appropriate height is adjusted to support the sleeper. According to calculation, a reasonable number of support devices and spacing positions are placed to stably support the entire track frame and keep the geometric frame of the track stable. After that, the entire section that needs to be broken and screened can be cleaned.

[0010] Preferably, the telescopic structure is a hydraulic jack.

[0011] In this technical solution, it should be noted that the use of hydraulic jacks has a smaller supporting area than wood, and is more conducive to construction such as ballast bottom breaking and screening, as well as the repair and remediation of roadbed diseases.

[0012] Preferably, one side of the expansion member is a curved surface adapted to the side wall of the telescopic structure.

[0013] In this technical solution, it should be noted that when the hydraulic jack is not needed, the expansion member can be rotated so that the arc surface of the expansion member fits with the telescopic structure, thereby reducing the overall volume of the telescopic structure for easy storage and transportation.

[0014] Preferably, a first rubber pad is provided at the bottom of one end of the expansion member away from the telescopic structure, and a second rubber pad is provided at the bottom of the telescopic structure, and the bottoms of the first rubber pad and the second rubber pad are flush.

[0015] In this technical solution, it should be noted that the supporting stability of the telescopic structure is further increased by providing a rubber pad.

[0016] Preferably, the first rubber pad is detachably connected to the extension member; a connecting plate is provided on the top of the first rubber pad, a threaded hole is provided on the top of the connecting plate, and a stud threadedly matched with the threaded hole is provided on the bottom of the extension member.

[0017] In this technical solution, it should be noted that the threaded holes and studs are provided to facilitate replacement of the first rubber pad.

[0018] Preferably, a mounting plate is provided on the bottom side wall of the telescopic structure, a vertical shaft is fixedly connected to the mounting plate, the expansion member is sleeved on the vertical shaft, and is hinged to the telescopic structure through the vertical shaft; a clamping device for clamping or loosening the expansion member is provided on the vertical shaft. The clamping device includes a nut, the nut is threadedly connected to the vertical shaft, and the nut is located above the expansion member. The clamping device also includes a gasket, the gasket is sleeved on the vertical shaft, and the gasket is located between the nut and the expansion member.

[0019] In this technical solution, it should be noted that when the stored expansion member needs to be unfolded, the nut is first pulled to move the nut upward along the vertical axis. At this time, the expansion member is loosened, and the staff then rotates the expansion member to unfold it. After unfolding, the nut is rotated in the opposite direction to move the nut downward and cooperate with the gasket to tighten the expansion member to ensure the stability of the expansion member.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0021] 1. In the utility model, the telescopic structure can support sleepers of different heights. Secondly, in the present solution, an expansion member is provided. When the expansion member is rotated and unfolded, the coverage of the telescopic structure on the ground is increased, so that the telescopic structure will basically not fall down due to the shift of the center of gravity, so as to ensure the normal use and safety of the telescopic structure.

[0022] 2. In the utility model, when it is necessary to unfold the stored expansion member, first pull the nut so that the nut moves upward along the vertical axis. At this time, the expansion member is loosened, and the staff then rotates the expansion member to unfold the expansion member. After unfolding, the nut is rotated in the opposite direction to move downward and cooperate with the gasket to tighten the expansion member to ensure the stability of the expansion member.

The telescopic structure 20 can support sleepers 10 of different heights. Secondly, in the present solution, an expansion member 30 is provided. When the expansion member 30 is rotated and unfolded, the coverage of the telescopic structure 20 on the ground is increased, so that the telescopic structure 20 will basically not fall over due to the shift of the center of gravity, so as to ensure the normal use and safety of the telescopic structure 20. In the present solution, when the railway needs to be broken and screened, the hollowing needs to support the bottom of the sleeper 10, and the other sleepers 10 remain supported to ensure the stability of the track frame. After that, the ground at the hollowing position is cleaned and leveled, the telescopic structure 20 is placed on the ground, and the appropriate height is adjusted to support the sleeper 10. According to calculation, a reasonable number of support devices and spacing positions are placed to stably support the entire track frame, and the geometric frame of the track is kept stable.

It should be noted that when the stored expansion member 30 needs to be unfolded, the nut 42 is first pulled to move the nut 42 upward along the vertical axis 41. At this time, the expansion member 30 is loosened, and the staff then rotates the expansion member 30 to unfold the expansion member 30. After unfolding, the nut 42 is rotated in the opposite direction to move the nut 42 downward and cooperate with the gasket 43 to tighten the expansion member 30 to ensure the stability of the expansion member 30.

[0044] The working principle of this embodiment is:

[0045] When it is necessary to perform bottom cleaning and screening on the railway, the hollowing needs to support the bottom of the sleeper 10, and the other sleepers 10 remain supported and motionless to ensure the stability of the track frame. Then, the ground at the hollowing position is cleaned and leveled, and then the expansion member 30 on the telescopic structure 20 is unfolded, that is, the nut 42 is pulled to make the nut 42 move upward along the vertical axis 41. At this time, the expansion member 30 is loosened, and the staff rotates the expansion member 30 again to unfold the expansion member 30. After unfolding, the nut 42 is rotated in the opposite direction to make the nut 42 move downward and cooperate with the gasket 43 to tighten the expansion member 30 to ensure the stability of the expansion member 30. After the expansion member 30 is unfolded, the telescopic structure 20 is placed on the ground, and the appropriate height is adjusted to support the sleeper 10. According to calculation, a reasonable number of support devices and spacing positions are placed to stably support the entire track frame and keep the geometric frame of the track stable.
