Description

Technical Field

[0001] This utility model relates to a turnout longitudinal traction laying machine based on a turnout longitudinal traction flatcar, belonging to the technical field of large-scale railway engineering construction machinery. Background Technology

[0002] The applicant filed an invention patent application on June 12, 2015, for a railway turnout longitudinal moving device and its moving method. This application was granted on June 23, 2017, with patent number ZL 201510321573.9 (hereinafter referred to as: railway turnout longitudinal moving flatcar). Currently, the turnout longitudinal moving flatcar developed based on this patent has entered the market and has been well applied in railway turnout replacement construction. It reduces safety risks and labor intensity while also reducing construction procedures and saving track maintenance time, making a positive contribution to railway turnout replacement construction. Although this patented product has achieved positive results in railway turnout replacement construction, further development of supporting products is needed to improve the efficiency of railway turnout replacement construction.

[0003] The use of railway turnout longitudinal moving flatcars requires excavators to provide traction. Due to railway catenary safety requirements, only small and medium-sized excavators are permitted; large excavators are not allowed to be used under the railway catenary. When the longitudinal movement direction of the turnout is that the turnout tail enters the slotted foundation first, small and medium-sized excavators cannot vertically lift the turnout tail. Therefore, hydraulic turnout lifting equipment is needed to raise the turnout tail, and the railway turnout longitudinal moving flatcar is manually placed under the turnout tail. This process is repeated repeatedly during the longitudinal movement of the turnout. Because small and medium-sized excavators provide horizontal traction, hydraulic turnout lifting equipment provides vertical lifting, and the turnout longitudinal moving flatcar needs to be manually moved and installed, these three aspects not only require close coordination but also take a long time. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a turnout longitudinal traction laying machine based on a turnout longitudinal traction flatcar. This laying machine can solve the problems of horizontal traction of turnout longitudinal movement, vertical lifting of turnout, and manual laying of turnout longitudinal traction flatcar, realizing one-machine operation, single-person operation, smooth process, saving time and improving efficiency.

[0005] To solve the above problems, the specific technical solution of this utility model is as follows: A turnout longitudinal traction laying machine based on a turnout longitudinal traction flatcar includes a chassis traveling part, a rotating body part and a rotating working arm.

[0021] Figure 5 This is a schematic diagram showing the connection between the sleeper hook and the ground anchor in the main view direction. Detailed Implementation

[0022] like Figure 1 and Figure 2 As shown, a turnout longitudinal traction laying machine based on a turnout longitudinal traction flatcar is a special equipment obtained by modifying an excavator structure. The turnout longitudinal traction laying machine includes a chassis traveling section 1, a rotating body section 2, and a rotating working arm 3. The chassis traveling section 1, the rotating body section 2, and the internal hydraulic and electrical circuits are all existing excavator structures. The modified structure is as follows: the rotating body section 2 is located at one end above the chassis traveling section 1, the rotating working arm 3 is connected to one end of the rotating body section 2, and the end of the rotating working arm 3 is connected to a rotary material clamp 4 via a clamping cylinder 10; the fixed working arm 5 is fixedly connected to the other end of the chassis traveling section 1, and the end of the fixed working arm 5 is connected to an L-shaped sleeper hook foot 15. The sleeper hook foot 15 is used to extend from the space of the turnout sleeper 32 into the space below the sleeper to hook the sleeper, so as to facilitate the dragging of the turnout.

[0023] The fixed working arm 5 has a hollow structure at its end, and a ground support cylinder 16 is installed inside the cavity. The piston rod of the ground support cylinder 16 is connected to a foot 17. After the foot 17 is supported, the sleeper hook foot 15 moves upward, realizing the upward movement of the turnout sleeper.

[0024] like Figure 4 and Figure 5 As shown, the L-shaped sleeper hook foot 15 is composed of two wedge-shaped upright plates I15-1 and a cover plate 15-2 on both sides; one end of the two wedge-shaped upright plates I15-1 is fixedly connected to the end of the fixed working arm 5, and the upper surfaces of the two wedge-shaped upright plates I15-1 are connected to the lower surface of the cover plate 15-2; the end of the sleeper hook foot 15 faces the chassis traveling part 1.

[0025] The foot 17 consists of two wedge-shaped vertical plates II17-1 and a base plate 17-2; the side ends of the wedge-shaped vertical plates II17-1 are fixedly connected to the piston rod of the support cylinder 16, and the lower surfaces of the two wedge-shaped vertical plates II17-1 are connected to the base plate 17-2; the foot 17 faces the same direction as the sleeper hook foot 15; and when the two wedge-shaped vertical plates II17-1 rise to the top, they are located between the two wedge-shaped vertical plates I15-1.

[0026] The rotating working arm 3 and the fixed working arm 5 have the same structure, both consisting of a boom 11, a boom cylinder 12, a forearm 13, and a forearm cylinder 14. One end of the boom 11 is hinged to the forearm 13, and the other end is hinged to the rotating vehicle body 2. One end of the boom cylinder 12 is hinged to the rotating vehicle body 2, and the other end is hinged to the boom 11. One end of the forearm cylinder 14 is hinged to the boom 11, and the other end is hinged to the forearm 13. The boom 11 is moved by controlling the boom cylinder 12, and the forearm cylinder 14 is moved by controlling the forearm cylinder 14.

[0027] Two material loading boxes 18 are provided on the upper part of one end of the chassis traveling part 1, and the material loading boxes 18 are symmetrically arranged on both sides of the fixed working arm 5. Multiple turnout longitudinal moving flatcars can be arranged in the material loading boxes 18 and picked up and put in sequence by rotating the working arm 3.

[0028] like Figure 3 As shown, a turnout longitudinal traction laying machine based on a turnout longitudinal traction flatcar is used. When the turnout is longitudinally moved to the slotted foundation bed on the existing track, the driver operates the turnout longitudinal traction laying machine to the front of the new turnout, and extends the sleeper hook foot 15 at the end of the fixed working arm 5 from the space of the turnout sleeper 32 into the space under the sleeper to hook the sleeper. The turnout longitudinal traction laying machine is driven to move backward, dragging the turnout longitudinally backward on the turnout longitudinal traction flatcar 33. After the turnout has moved a suitable distance, the driver operates the ground support cylinder 16 at the end of the fixed working arm 5 to ground the foot 1. The 7-axis support is engaged, and the sleeper hook foot 15 is driven upward to raise the front end of the turnout. Then, the driver operates the rotating working arm 3 to grab the turnout longitudinal moving flatcar 33 in the material loading box 18. Through the rotational cooperation of the rotating mechanical arm and the rotating material clamp 9, the turnout longitudinal moving flatcar 33 is placed in pairs under the turnout sleeper at the front end of the turnout. Then, the retracting support cylinder 16 presses the turnout onto the turnout longitudinal moving flatcar 33. The turnout longitudinal moving traction laying machine continues to move backward. The above operation is repeated several times until the turnout is in place.
