DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] Example 1:

[0031] like Figures 1-8 As shown, the small track laying device includes a propulsion platform 2, a front end support platform 3, an upper traveling frame 4 and a sleeper transporting member 5; the propulsion platform 2 includes a mobile cart 21 and a first guide rail 22, the front end support platform 3 includes a first support beam 31, a second guide rail 32 and a first support member 34, the mobile cart 21 is arranged on the laid rail 10, the front end of the mobile cart 21 is hinged to one end of the first support beam 31, and the first support member 34 is arranged at the other end of the first support beam 31; the first guide rail 22 and the second guide rail 32 that cooperate with each other are respectively arranged on the mobile cart 21 and the first support beam 31; the upper traveling frame 4 is arranged on the first guide rail 22, and the sleeper transporting member 5 is arranged on the upper traveling frame 4; the sleeper transporting member 5 is arranged to be raised and lowered along the vertical direction.

[0032] During operation, the rails 11 to be laid and the sleepers to be laid are placed on the mobile cart 21 (including the necessary roller drive and braking mechanism), and the mobile cart 21 is moved to the laid rails 10 close to the area to be laid. At this time, the first support beam 31 and the first support member 31 (which can be a hydraulic telescopic rod, a jack, etc.) in the front support platform 3 are located in the ballast in the area to be laid. Through the supporting effect of the first support member 31, the second guide rail 32 is basically in a horizontal state; the sleeper transporting member 5 descends to grab the sleeper to be laid, and then rises; then the upper traveling frame 4 (including the necessary roller drive and braking mechanism) is controlled to move to the second guide rail 32. Every time it moves a certain distance, the sleeper transporting member 5 and the sleeper transporting member descend close to the ballast, a piece of rail The sleeper is placed on the ballast, and then continues to move forward until it moves to the maximum travel range of the second guide rail 32, and then the upper walking frame 4 returns to the first guide rail 21 to stand by, completing the transportation and stacking operations of the sleepers; then the rails on the mobile cart 21 are manually pulled to the sleepers in the area to be laid, and after adjusting the position, the fixing and laying operations of the rails to be laid and the sleepers to be laid are completed, and then the front end of the front support platform 3 is lifted, and the mobile cart 21 is driven to move forward the distance of one rail, and the above actions are repeated to complete the subsequent rail laying operations; this rail laying device is suitable for small-scale laying operation scenarios, and can realize the sequential transportation and stacking of sleepers and rails, which can improve the efficiency of laying operations and reduce labor intensity.

[0033] Example 2:

[0034] like Figures 1-8 As shown, with respect to the above embodiment, this embodiment optimizes the support block structure of the sleeper transporting member.

[0035] The sleeper handling member 5 in this small track laying device includes a second telescopic member 50, a first crossbeam 51, and sleeper clamps 52. The first crossbeam 51 is connected to the upper running frame 4 via the second telescopic member 50, and multiple sets of sleeper clamps 52 are provided at the bottom of the first crossbeam 51. The second telescopic member 50 is also a hydraulic telescopic rod or screw used to drive the first crossbeam 51 to raise and lower. The sleeper clamps 52 can adopt existing sleeper clamp structures and are used to grasp and release sleepers.

[0036] Example 3:

[0037] like Figures 1-8 As shown, with respect to the above embodiments, this embodiment optimizes the track traction structure.

[0038] In this small track laying device, a rail pulling unit 8 is installed at the end of the first support beam 31 away from the mobile cart 21. The rail pulling unit 8 includes a second electric hoist 81, a second steel wire rope 82, and a rail clamp 83. The second electric hoist 81 is fixed to the first support beam 31. The rail clamp 83 is installed at one end of the second steel wire rope 82, and the other end is connected to the second electric hoist 81. After the sleepers are stacked, the second electric hoist 81 drives the second steel wire rope 82 to reel in, and the rail, which is clamped to the rail clamp 83, is pulled out of the mobile cart 21, improving operation convenience and reducing manual labor intensity.

[0039] Example 4:

[0040] like Figures 1-8 As shown, with respect to the above embodiments, this embodiment optimizes the supporting structure.

[0041] In this small track laying device, a plurality of second support members 34 are provided at the bottom of the first support beam 31. The second support member 34 can be a hydraulic telescopic rod or a jack structure, which is used to support the first support beam 31 and improve the load-bearing capacity and stability of the second guide rail 32.

[0042] Example 5:

[0043] like Figures 1-8 As shown, with respect to the above embodiments, this embodiment optimizes the front end support platform structure.

[0044] In this small track laying device, rollers are provided at the bottom of the first support member 34. The rollers 34 enable the front end of the first support beam 31 to have a certain degree of passive walking ability when driven by the moving platform 21, allowing it to move directly on the ballast to be laid (manual guidance only requires control).

[0045] Example 6:

[0046] like Figures 1-8 As shown, with respect to the above embodiments, this embodiment optimizes the front end support platform structure.

[0047] In this small track laying device, a third electric hoist 91 is installed on the upper traveling frame 4. The third electric hoist 91 is connected to the first support beam 31 via a third steel wire rope 92. After a section of track is laid, the third electric hoist 91 is used to lift the first support beam 31 upward (the first support beam 31 is hinged to the mobile cart 21). After the mobile cart 21 is moved to the appropriate position, the third electric hoist 91 is used to lower the first support beam 31, making the front support platform more convenient to retract and extend.

[0048] Example 7:

[0049] like Figures 1-8As shown, with respect to the above embodiments, this embodiment optimizes the rail transport structure.

[0050] In this small track laying device, first electric hoists 43 are provided on both sides of the upper traveling frame 4. The first electric hoists 43 facilitate lifting the rails, thereby facilitating the handling operation of the rails.

[0051] One application scenario is: the first electric hoist 43 is used to move the rails 11 to be laid onto the mobile cart 21 to facilitate the subsequent laying operation;

[0052] Another application scenario is: the first electric hoist 43 is used to pull the rails to be laid on the mobile cart 21 to the area to be laid;

[0053] Another application scenario is: after the guide rail 11 to be laid is dragged to the area to be laid by the second electric hoist 81, the upper traveling frame 4 is moved, and the first electric hoist 43 is used to lift the rail, which facilitates the adjustment of the position of the rail 11 to be laid and reduces manual labor.

[0054] Example 8:

[0055] like Figures 1-8 As shown, with respect to the above embodiments, this embodiment optimizes the rail anti-falling structure.

[0056] In this small track laying device, a rail anti-falling component 36 is provided on the first support beam 31. The rail anti-falling component 36 includes a first telescopic component 361 and a cross bar 362. The base of the first telescopic component 361 is hinged to the first support beam 31, the telescopic end of the first telescopic component 361 is hinged to the cross bar 362, and one end of the cross bar 362 is rotatably connected to the first support beam 31. Since a single rail is relatively long, it has a certain degree of flexible deformation ability. During the process of dragging the rail to be laid, if the rail has not completely separated from the mobile cart 21, it will form a drooping state in the area to be laid, which is prone to collision and contact with the ballast, resulting in failure of the rail pulling operation; therefore, a rail anti-falling member 36 is provided, and when the rail is dragged, the cross bar 362 is in an extended state (perpendicular to the first support beam 31), providing a bottom support for the rail; when the rail is completely separated from the mobile cart 21, the first telescopic member 361 is controlled to retract the cross bar 362 (close to the first support beam 31), so that the rail can fall on the sleeper for subsequent rail fixing operations.

[0057] Example 9:

[0058] like Figures 1-8 As shown, with respect to the above embodiments, this embodiment optimizes the structure of the sleeper transporting member.

[0059] In this small track laying device, multiple sets of third telescopic members 54 are installed on the first crossbeam 51. The second crossbeam 53 is installed at the bottom of the third telescopic members 54, and rail sleeper clamps 52 are installed at both ends of the second crossbeam 53. The third telescopic members 54 cooperate with the second telescopic members 50 to increase the vertical travel range of the rail sleeper clamps 52, making it easier to grasp and place rail sleepers.

[0060] By setting up multiple sets of sleeper clamps and the third telescopic member, it is possible to realize the independent lifting and lowering operation of a single set of sleepers, which is convenient for the later fixed-distance stacking of sleepers.

[0061] Example 10:

[0062] like Figures 1-8 As shown, with respect to the above embodiment, this embodiment optimizes the lifting structure.

[0063] In this small track laying device, a guide post 42 is fixedly provided on the frame body 41 of the upper traveling frame 4, and the guide post 42 passes through the first crossbeam 51 and is slidably connected thereto. The guide post 42 is provided to improve the stability during the sleeper lifting operation.

[0064] Preferably, two groups of support rods 23 are provided on the mobile cart 21 between the two groups of first guide rails 22, and the top of the two groups of support rods 23 is used to place the sleepers to be laid (perpendicular to the first guide rails). At this time, there is a storage area between the two groups of support rods 23 and below the sleepers to be laid, which can prevent the guide rails 11 to be laid, greatly improving the single storage space of the mobile cart 21; and when the guide rails are laid, the sleepers are laid first, and then the rails are laid. The sleepers are transported by lifting and the rails are transported by dragging, which does not affect the operations of both. While improving the storage efficiency, the laying operation efficiency can be greatly improved.

[0065] The power unit 6 includes necessary power source components such as electricity and oil pump stations to provide power sources for corresponding operating units; the control room 7 can be set on the upper traveling frame 4 to control the operating components following the movement of the upper traveling frame 4.

[0066] Although the present invention has been described herein with reference to a number of illustrative embodiments thereof, it will be understood that numerous other modifications and implementations may be devised by those skilled in the art that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the present disclosure, the drawings, and the claims, numerous variations and modifications may be made to the components and / or layout of the subject combination arrangement. In addition to variations and modifications to the components and / or layout, other uses will also be apparent to those skilled in the art.
