Description

Technical Field

[0001] This utility model relates to the field of tamping equipment technology, specifically a trolley for tamping device replacement of DCL-32k continuous tamping machine. Background Technology

[0002] The DCL-32k tamping machine is used for railway line operations to eliminate track geometry deviations. The tamping device has 32 picks and operates in a step-by-step manner. It can complete the lifting, leveling, tamping, and end compaction of two sleepers in one operation according to pre-set track geometry parameters. The tamping device needs to be replaced after its service life or when problems arise.

[0003] The tamping device of the DCL-32K weighs approximately 3 tons. During the tamping process, it generally needs to be returned to the garage or a leveled surface for hoisting using an overhead crane or forklift. Traditional forklifts are bulky and inconvenient to carry, making it difficult to quickly reach the site when tamping is required. Furthermore, forklifts typically have a tilt angle of 3-6° and a back tilt angle of 10-13°, suitable for relatively flat surfaces. However, the rails at tamping sites are usually sloping ballast slopes, with the angle between the slope and the horizontal plane much greater than the tilt angle of the forklift, making traditional forklifts unsuitable for on-site tamping needs. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a trolley for changing the tamping device of the DCL-32k continuous tamping machine.

[0005] The technical solution of this utility model is:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] A trolley for changing the tamping device of a DCL-32k continuous tamping machine includes:

[0029] The movable component 1 includes a gantry 11. Movable frames are provided on the front and rear sides of the bottom of the gantry 11. The angle of the rear movable frame is adjustable. A changing frame 3 is installed on the front side of the gantry 11 via a lifting component 2. The lifting component 2 is used to drive the changing frame 3 to move along the axis of the gantry 11. The changing frame 3 includes a bracket 33. A pushing device is provided on the top surface of the front side of the bracket 33. The pushing device is used to support the tamping device and drive the tamping device to move in the horizontal direction.

[0030] The gantry 11 is made of welded steel plates and is the main load-bearing structure of the device.

[0031] The mobile frame includes a first mobile frame 12 and a second mobile frame 14. The first mobile frame 12 is welded and installed at the bottom front side of the gantry 11, and the head of the first mobile frame 12 is rotatably mounted with a mobile wheel 13.

[0032] The first movable frame 12 and the movable wheel 13 are used for load-bearing on the front side of the device. The movable wheel 13 can only rotate axially and is used for moving the device.

[0033] The second movable frame 14 is rotatably mounted on the rear side of the gantry 11. The head of the second movable frame 14 is rotatably mounted with casters 16, and the top of the second movable frame 14 and the middle of the gantry 11 are rotatably mounted with the first hydraulic cylinder 15.

[0034] The second movable frame 14, the first hydraulic cylinder 15, and the casters 16 are used for load-bearing on the rear side of the device.

[0035] When the first hydraulic cylinder 15 is working, it can drive the second movable frame 14 to rotate up and down, thereby adjusting the angle of the second movable frame 14. The casters 16 can easily change the forward direction of the device.

[0036] The second mobile frame 14 has a power source 17 on its top surface in the middle, which is used to provide hydraulic power.

[0037] Power source 17 can be a diesel-hydraulic power station, which uses a diesel engine to drive a hydraulic pump to generate hydraulic energy, which is then used to power components of the device that require hydraulic drive through the hydraulic system.

[0038] The weight of the power source 17 itself can also provide some support for the device, allowing the device's center of gravity to shift backward.

[0039] If necessary, additional counterweights can be placed on the second movable frame 14.

[0040] The lifting assembly 2 includes a second hydraulic cylinder 21, which is connected to a sliding frame 24 via a transmission structure. The sliding frame 24 clamps the gantry 11 on its back via guide wheels 25. The changing frame 3 is installed on the front side of the gantry 11.

[0041] The transmission structure includes a pulley 22, which is rotatably mounted on the top of the piston rod of the second cylinder 21. A chain 23 is slidably connected to the pulley 22, with one end of the chain 23 fixedly connected to the cylinder barrel of the second cylinder 21 and the other end fixedly connected to the top of the sliding frame 24. When the second cylinder 21 is working, it can drive the pulley 22 to move vertically, thereby driving the sliding frame 24 to move via the chain 23. In conjunction with the guide wheel 25, it can drive the sliding frame 24 to move along the axis of the gantry 11.

[0042] The changing frame 3 includes a mounting frame 31, which is fixedly mounted on the front side of the sliding frame 24 by bolts, and the bracket 33 is slidably mounted on the front side of the mounting frame 31 by a guide rod 32.

[0043] The bracket 33 slides along the guide rod 32, which can adjust the distance between the two brackets 33 to facilitate alignment with the lifting point of the tamping device. When the sliding frame 24 moves, it can drive the bracket 33 to move through the mounting frame 31.

[0044] The pushing assembly includes a tray 35, which is slidably connected to a bracket 33 via a guide rail 34. A third hydraulic cylinder 36 is fixedly installed between the rear side of the tray 35 and the bracket 33.

[0045] When the third cylinder 36 is working, it can drive the pallet 35 to move along the guide rail 34.

[0046] When the pallet 35 moves to the head of the bracket 33, it can easily lift the tamping device. When the pallet 35 moves towards the third cylinder 36, it can drive the tamping device to move, so that the tamping device is close to the gantry 11 and the center of the device is located between the first moving frame 12 and the second moving frame 14, thus preventing the device from tipping forward.

[0047] In this embodiment, when the operator uses this equipment, the device is removed from the tool cart behind the tamping machine and pushed to move the device towards the tamping device.

[0048] Control the operation of power source 17 to prepare for subsequent work.

[0049] After being pushed to the top of the slope, the first hydraulic cylinder 15 can be controlled to work, driving the second moving frame 14 to rotate downwards, thereby driving the gantry 11 to move forward and keeping the gantry 11 in a vertical state.

[0050] Align the bracket 33 with the lifting point below the tamping device, control the second hydraulic cylinder 21 to work, drive the pulley 22 to move upward in the vertical direction, thereby driving the sliding frame 24 to move through the chain 23.

[0051] When the sliding frame 24 moves, it can drive the bracket 33 to move via the mounting frame 31.

[0052] When the bracket 33 moves upward, the third hydraulic cylinder 36 drives the pallet 35 to move along the guide rail 34 to the head of the bracket 33.

[0053] After the support plate 35 supports the tamping device, the second cylinder 21 and the third cylinder 36 stop working and maintain pressure.

[0054] After removing the fixing bolts of the tamping device, control the second hydraulic cylinder 21 to drive the bracket 33 to move downward, so that the tamping device is separated from the tamping vehicle. Then control the third hydraulic cylinder 36 to drive the support plate 35 to move backward, thereby driving the tamping device to approach the gantry 11.

[0055] Then, control the first hydraulic cylinder 15 to work, drive the second moving frame 14 to move upward until the second moving frame 14 and the first moving frame 12 are parallel, and push the device to transfer the tamping device away from the tamping vehicle.

[0056] The new tamping device can then be moved to the installation position for installation.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
