Description

Technical Field

[0001] This utility model relates to the field of urban rail transit, and in particular to a novel sleeper laying device for urban rail transit. Background Technology

[0002] An existing patent (publication number: CN222809802U) proposes a new type of sleeper laying device for urban rail transit, including a base frame, a material feeding plate, and rollers. The material feeding plate is fixedly connected to the base frame, and several rollers are rotatably connected to the material feeding plate. However, in this device, "the first sleeper will slide down along the rollers to the position to be laid, so that the sleepers in the loading frame can be laid intermittently." After the sleeper falls, it may tilt slightly, requiring manual correction, which affects the overall laying efficiency. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a new type of urban rail transit sleeper laying device that results in more regular sleepers after laying, eliminates the need for subsequent manual straightening, saves manpower, and increases laying efficiency.

[0004] The objective of this utility model is achieved through the following technical solution: A novel sleeper laying device for urban rail transit includes a main support frame, a carrying conveyor belt, a sleeper to be laid, a feeding drive motor, and a straightening wheel. The main support frame has carrying roller connecting grooves on both sides and a sleeper carrying groove inside the main support frame. A sleeper carrying roller is installed inside the sleeper carrying groove. The sleeper carrying roller has carrying roller connecting ears on both sides, which are rotatably connected to the carrying roller connecting groove. The carrying conveyor belt is sleeved on the outside of the sleeper carrying roller array. The sleeper to be laid is placed on the upper part of the carrying conveyor belt. A carrying platform connecting frame is located on the lower side of the main support frame. A power carrying platform is located on the top of the carrying platform connecting frame. The feeding drive motor is fixedly connected to the top of the power carrying platform. The surface of the power carrying platform has an outer sleeve positioning groove and an inner sleeve positioning groove. The outer sleeve positioning groove is located on the lower side of the feeding drive motor, and the inner sleeve positioning groove is located on the higher side of the feeding drive motor. The feeding drive motor has a transmission shaft that is fixedly connected to a lifting drive block. The side surface of the lifting drive block has a drive groove.

[0005] The bottom of the inner sleeve positioning groove is provided with an inner lifting sleeve, and the top of the inner lifting sleeve is provided with an inner sleeve positioning rod. The inner sleeve positioning rod is adapted to the inner sleeve positioning groove and is connected to the inner sleeve positioning groove. The inner sleeve positioning rod slides inside the inner sleeve positioning groove. The bottom of the outer sleeve positioning groove is provided with an outer lifting sleeve, and the top of the outer lifting sleeve is provided with an outer sleeve positioning rod. The outer sleeve positioning rod is adapted to the outer sleeve positioning groove and is connected to the outer sleeve positioning groove. The outer sleeve positioning rod slides inside the outer sleeve positioning groove. The side of the outer lifting sleeve facing the inner lifting sleeve is provided with a sleeve positioning groove. The side of the inner lifting sleeve facing the outer lifting sleeve is provided with a sleeve positioning slider. The sleeve positioning slider is adapted to the sleeve positioning groove and is connected to the sleeve positioning groove. The sleeve positioning slider slides inside the sleeve positioning groove.

[0006] Both the outer and inner lifting sleeves have curved groove connecting blocks on their inner sides. The side surface of the lifting drive block has a driving curved groove. The curved groove connecting block is adapted to the driving curved groove and is connected to the driving curved groove. The curved groove connecting block slides inside the driving curved groove. The bottom of the inner lifting sleeve has an inner lifting baffle, and the bottom of the outer lifting sleeve has an outer lifting baffle. The inner side of the bearing platform connecting frame has an outer baffle positioning groove and an inner baffle positioning groove. The inner lifting baffle is adapted to the inner baffle positioning groove and is connected to the inner baffle positioning groove. The inner lifting baffle slides inside the inner baffle positioning groove. The outer lifting baffle is adapted to the outer baffle positioning groove and is connected to the outer baffle positioning groove. The outer lifting baffle slides inside the outer baffle positioning groove.

[0007] Beneficial effects: 1. When laying sleepers for urban rail transit, the lifting drive block drives the outer lifting baffle to rise while the inner lifting baffle descends, so that only one sleeper to be laid descends to complete the sleeper laying. At the same time, the two sets of straightening platforms move closer to each other as the outer lifting baffle rises, so that the falling sleeper to be laid is straightened, making the laid sleepers more regular. No further manual straightening is required, which saves more manpower and increases the laying efficiency.

[0008] 2. In this utility model, the outer lifting baffle slides inside the outer baffle positioning groove, and the inner lifting baffle slides inside the inner baffle positioning groove. When the outer lifting baffle and the inner lifting baffle are subjected to lateral forces from the sleeper to be laid, the outer baffle positioning groove and the inner baffle positioning groove can respectively provide auxiliary support for the outer lifting baffle and the inner lifting baffle, making the outer lifting baffle and the inner lifting baffle less prone to bending during use and increasing the service life of the outer lifting baffle and the inner lifting baffle.

[0009] 3. The straightening platform and the straightening wheel of this utility model are rotatably connected, so that when the straightening platform straightens the sleeper to be laid, the friction between the straightening wheel and the sleeper to be laid is rotational friction. The rotational friction between the straightening wheel and the sleeper to be laid is less than the friction between the sleeper to be laid and the ground, thereby preventing the straightening platform from taking the sleeper to be laid away from its falling position when straightening, and ensuring the stability of the sleeper to be laid during laying.

The feeding drive motor 8 has a transmission shaft that is fixedly connected to the lifting drive block 31. The side surface of the lifting drive block 31 has a drive curved groove 30. When laying sleepers in urban rail transit, the lifting drive block 31 drives the outer lifting baffle 25 to rise while the inner lifting baffle 26 falls, so that only one sleeper 5 to be laid falls to complete the sleeper laying. At the same time, the two sets of straightening platforms 9 move closer to each other as the outer lifting baffle 25 rises, so that the falling sleeper 5 to be laid is straightened, making the laid sleepers more regular and eliminating the need for subsequent manual straightening, thus saving manpower and increasing laying efficiency.

[0020] Example 2: The inner sleeve positioning groove 21 of this utility model is provided with an inner lifting sleeve 27 at the bottom, and an inner sleeve positioning rod 23 at the top of the inner lifting sleeve 27.

The outer lifting baffle 25 is connected to the outer baffle positioning groove 35 and slides inside the outer baffle positioning groove 35. The inner lifting baffle 26 slides inside the inner baffle positioning groove 36. When the outer lifting baffle 25 and the inner lifting baffle 26 are subjected to lateral forces from the sleeper 5 to be laid, the outer baffle positioning groove 35 and the inner baffle positioning groove 36 can provide auxiliary support for the outer lifting baffle 25 and the inner lifting baffle 26 respectively, making the outer lifting baffle 25 and the inner lifting baffle 26 less prone to bending during use and increasing the service life of the outer lifting baffle 25 and the inner lifting baffle 26.

[0022] Example 4: The outer lifting sleeve 24 of this utility model has a central connecting rod mounting platform 17 on the side away from the inner lifting sleeve 27.
