[0029] Example 1

[0030] like Figures 1 to 4 As shown, a tamping vehicle is disclosed, which includes a trolley 2 moving along a steel rail 1, a first driving device arranged on the trolley 2, a tamping mechanism 3 connected to the output end of the first driving device so as to be lifted up and down relative to the trolley 2, and an adjusting mechanism for adjusting the tamping angle of the tamping mechanism 3 is also arranged on the trolley 2; a controller is arranged on the trolley 2, and the trolley 2, the first driving device and the adjusting mechanism are communicatively connected to the controller.

[0031] In the present application, the trolley 2 moves along the rail 1, and the tamping mechanism 3 is arranged on the trolley 2, and moves with the trolley, so as to operate continuously. When the trolley 2 reaches the operating area, the trolley 2 stops moving. At this time, the first drive device arranged on the trolley 2 is started, and the tamping mechanism 3 connected to the output end of the first drive device descends to the operating area and starts the tamping operation. The tamping mechanism 3 completes the tamping operation of the area directly below it. At the same time, an adjustment mechanism is also provided on the trolley 2, and the tamping angle of the tamping mechanism 3 is adjusted by the adjustment mechanism. Specifically, the angle between the tamping mechanism 3 and the trolley 2 is adjusted by the adjustment mechanism, so that the tamping mechanism 3 can perform tamping operations on other areas other than directly below it, thereby increasing the operating range.

[0032] In order to facilitate the trolley 2 to walk on the rail 1, a running wheel can be set at the bottom of the trolley 2. Specifically, four running wheels can be set, respectively at the four corners of the trolley 2.

[0033] Example 2

[0034] Disclosed is a tamping vehicle, which includes a trolley 2 moving along a steel rail 1, a first drive device arranged on the trolley 2, a tamping mechanism 3 connected to an output end of the first drive device so as to be lifted up and down relative to the trolley 2, and an adjusting mechanism for adjusting the tamping angle of the tamping mechanism 3 is also arranged on the trolley 2; a controller is arranged on the trolley 2, and the trolley 2, the first drive device and the adjusting mechanism are communicatively connected to the controller.

[0035] The difference between this embodiment and the first embodiment is that, in order to facilitate the up and down lifting of the tamping mechanism 3, a mounting frame 4 can be slidably mounted on the trolley 2, and the tamping mechanism 3 is hingedly connected to the mounting frame 4. The output end of the first driving device is connected to the mounting frame 4. Under the action of the first driving device, the mounting frame 4 slides up and down relative to the trolley 2. When the mounting frame 4 slides up and down, the tamping mechanism 3 is inevitably driven to lift up and down. In order to facilitate the sliding of the mounting frame 4, a corresponding slide rail can be set on the trolley 2, and a pulley adapted to the slide rail 4 can be set on the mounting frame 4.

[0036] The first driving device may be a hydraulic cylinder, or a driving device with a telescopic function such as a telescopic cylinder.

[0037] The adjustment mechanism is also arranged on the mounting frame 4, and specifically comprises a second driving device 5 connected to the mounting frame 4, the output end of the second driving device 5 is connected to the connecting rod 6, the connecting rod 6 is hinged to the hinge rod 7, and the other end of the hinge rod 7 is hinged to the tamping mechanism 3. When the second driving device 5 is started, the tamping mechanism 3 will be driven to rotate relative to the mounting frame 4 under the action of the hinge, so as to adjust the angle between the tamping mechanism 3 and the mounting frame 4.

[0038] The second driving device 5 can be a hydraulic cylinder, or a driving device with telescopic function such as a telescopic cylinder. The telescopic cylinder and the hydraulic cylinder are mature products in the industry, and their principles are not described in detail here.

[0039] Specifically, two mounting frames 4 can be provided on the trolley 2. The two mounting frames 4 are symmetrically distributed on both sides of the trolley 2, the second driving device 5 is connected to the middle section of the connecting rod 6, the two ends of the connecting rod 6 are respectively hinged to the hinged rod 7, and the two hinged rods 7 are respectively hinged to the tamping mechanisms 3 on both sides. Through the above design, when the second driving device 5 is started, it will drive the tamping mechanisms 3 on both sides to rotate synchronously, and the operating ranges of the two tamping mechanisms 3 can be adjusted simultaneously through an adjustment device.

[0040] In order to improve the operating stability of the tamping mechanism 3 and the stability of the structure of the device, the tamping mechanism 3 and the mounting frame 4 can be connected by a telescopic rod 12.

[0041] Example 3

[0042] Disclosed is a tamping vehicle, which includes a trolley 2 moving along a steel rail 1, a first drive device arranged on the trolley 2, a tamping mechanism 3 connected to an output end of the first drive device so as to be lifted up and down relative to the trolley 2, and an adjusting mechanism for adjusting the tamping angle of the tamping mechanism 3 is also arranged on the trolley 2; a controller is arranged on the trolley 2, and the trolley 2, the first drive device and the adjusting mechanism are communicatively connected to the controller.

[0043] The difference between this embodiment and the second embodiment is that during the tamping operation, the trolley 2 on the rail 1 will be jolted by vibration, causing the trolley 2 to shift or even tilt and overturn. To avoid the above situation, in this embodiment, a rail clamping mechanism 9 is provided on the trolley 2. The rail 1 is clamped by the rail clamping mechanism 9, thereby ensuring that the trolley 2 stops stably on the rail 1.

[0044] The rail clamping mechanism 9 specifically includes a base 10 connected to the trolley 2, and a cylinder 11 and a clamping claw 12 are provided on the base 10 for clamping or releasing the rail 1 under the action of the cylinder 11. The clamping claw 12 is hinged to the base 10, and the output end of the cylinder 11 is connected to a cross bar, and the cross bar and the clamping claw 12 are hinged through a connecting rod. Under the action of the cylinder 11, the clamping claw 12 rotates relative to the base 10, thereby clamping or releasing the rail 10.

[0045] To further improve the stability of the trolley 2 during the tamping operation, two clamping claws 12 may be provided on the rail clamping mechanism 9, and under the action of the oil cylinder 11, the two clamping claws 12 clamp the rail 1 from both sides. In this embodiment, the oil cylinder 11 may also be replaced by a drive device such as a telescopic cylinder.

[0046] Specifically, four rail clamping mechanisms 9 can be provided, corresponding to the four corners of the trolley 2 .

[0049] The difference between this embodiment and the third embodiment is that a controller is provided on the trolley 2. The travel drive of the trolley 2 is connected to the controller for communication, and the automatic travel of the trolley 2 on the rail 1 is controlled by the controller.

[0050] The controller is also connected to the first drive device and the second drive device 5. After reaching the working position and the trolley 2 is paused, the controller controls the first drive device to start, so that the tamping mechanism 3 is lowered to the ground. The controller can also be connected to the tamping mechanism 3 through communication, so as to control the start or pause of the tamping mechanism 3. The controller is also connected to the second drive device 5, so as to control the second drive device 5 to drive the adjustment mechanism to adjust the tamping angle.

[0051] Through the above design, the tamping vehicle can achieve continuous automatic operation.

The trolley 2 is also provided with an adjusting mechanism for adjusting the tamping angle of the tamping mechanism 3.

[0054] The difference between this embodiment and the above embodiment is that a battery pack is also provided on the trolley 2 to realize power supply and meet the power demand of the tamping vehicle. Specifically, the battery pack can be a lithium battery.

[0055] At the same time, a solar power generation device can also be provided on the trolley 2, and the solar power generation device is electrically connected to the battery pack. The solar power generation device generates electricity, thereby charging the battery pack, thereby increasing the endurance operation time of the tamping vehicle.
