Description

Technical Field

[0001] This utility model belongs to the technical field of tamping devices, specifically relating to a reinforced support tamping device. Background Technology

[0002] Tamping is one of the main tasks in the maintenance of ballast railway tracks, effectively improving track stability and ensuring safe train operation. The tamping device is the core component of the tamping operation, a device with combined vibration and clamping functions. The tamping pick transmits the vibration force generated by the vibration to the ballast, causing it to vibrate and move, increasing the density of the track bed. Simultaneously, under the clamping force, the tamping pick compresses the ballast in the sleeper gaps towards the bottom of the sleepers, making the ballast at the bottom of the sleepers more compact, improving track stability, and ensuring safe train operation.

[0003] In the prior art, such as the tamping device and tamping vehicle disclosed in CN222008500U, the tamping device directly drives the tamping components through a rotary actuator, achieving structural simplification and weight reduction, and improving the efficiency of tamping operations. However, the angle adjustment of its tamping components mainly relies on the overall rotation of the rotary actuator, and the adjustment range and accuracy are limited to a certain extent. This makes it difficult to meet the control requirements of the tamping angle under complex working conditions, which leads to unstable tamping quality and reduces the overall efficiency of the tamping operation.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] like Figure 1 As shown, a reinforced support tamping device is used to tamp railway sleepers. It includes a bearing component 100, an adjusting component 200 rotatably connected inside the bearing component 100, and a tamping component 300 rotatably connected to the output end of the adjusting component 200. The tamping component 300 is rotatably connected to the bearing component 100. The tamping component 300 performs tamping operations from both sides of the sleeper. The adjusting component 200 is used to adjust the tamping angle of the tamping component 300, thereby adapting to the tamping requirements of different sleepers and improving the quality and efficiency of the tamping operation.

[0037] like Figures 1-3 As shown, the load-bearing component 100 includes a casting 101, which is integrally formed by sand casting process, making the casting 101 a whole. Sand casting process helps to reduce internal defects of casting 101, such as porosity and shrinkage, thereby improving the structural strength and stability of casting 101 and enabling it to better withstand the impact and vibration during tamping operation.

[0038] like Figure 3 As shown, inclined plates 102 are fixedly connected to both sides of the bottom of the casting 101. Support plates 103 are fixedly connected to the bottom of the inclined plates 102. Support ears 104 are provided on both sides of the support plates 103. The support ears 104 provide rotation connection points for the pick arm 301 of the tamping assembly 300. A bracket 105 is fixedly connected to the outer side of one of the support plates 103. An oil tank 106 is fixedly connected to one side of the bracket 105. The oil tank 106 provides necessary hydraulic power support for the adjusting cylinder 205, the first pick lifting cylinder 306, and the second pick lifting cylinder 308. A bushing 107 is fixedly connected to the middle of the casting 101 and the oil tank 106. The bushing 107 cooperates with the bearing 202 on the vibration shaft 201 to ensure the smooth rotation of the vibration shaft 201.

[0039] like Figure 3 As shown, both sides of the bracket 105 are fixedly connected with reinforcing ribs, and the reinforcing ribs are fixedly connected to the outside of one of the support plates 103. The reinforcing ribs enhance the structural strength of the connection between the bracket 105 and the support plate 103, preventing the bracket 105 from deforming or even breaking due to excessive force.

[0040] like Figure 3As shown, a reinforcing rib 108 is fixedly connected to the inner side of the inclined plate 102. The bottom end of the reinforcing rib 108 is fixedly connected to the inner side of the support plate 103, which strengthens the structural strength and rigidity between the inclined plate 102 and the support plate 103, and can effectively distribute and bear the stress generated during the tamping operation. At the same time, the setting of the reinforcing rib 108 can also improve the stability and durability of the bearing component 100 and extend the service life of the tamping device.

[0041] like Figure 1 and Figure 2 As shown, both ends of one side of the casting 101 are provided with guide grooves 109, and guide posts 400 are inserted into the inside of the guide grooves 109.

[0042] like Figure 1 and Figure 4 As shown, the adjusting assembly 200 includes a vibration shaft 201, which is rotatably connected to the middle of the casting 101. Both ends of the vibration shaft 201 are rotatably fitted with flanges 203. The outer surface of the flanges 203 is fitted with mounting sleeves 204. An adjusting cylinder 205 is fixedly connected to the outer side of the mounting sleeve 204. A connecting sleeve 206 is fixedly connected to the output end of the adjusting cylinder 205. The connecting sleeve 206 is rotatably connected to the tamping assembly 300. By adjusting the extension and retraction of the cylinder 205, the tamping angle of the tamping assembly 300 can be controlled, achieving precise tamping of different sleepers, improving the quality and efficiency of tamping operations, and meeting the tamping requirements under complex working conditions.

[0043] like Figure 1 and Figure 4 As shown, bearings 202 are fitted at both ends of the outer surface of the vibration shaft 201. The bearings 202 are fixed inside the bushing 107, which reduces the friction between the vibration shaft 201 and the bushing 107, making the rotation of the vibration shaft 201 smoother.

[0044] like Figure 1 and Figure 5As shown, the tamping assembly 300 includes a pick arm 301 and a tamping actuator. The top of the pick arm 301 is provided with a mounting lug 302, and a connecting sleeve 206 is rotatably connected to the mounting lug 302. The middle part of the pick arm 301 is rotatably connected to a support lug 104. The tamping actuator is rotatably disposed on the outside of the pick arm 301 for tamping the sleepers. The tamping actuator includes a first pick-lifting cylinder 306 and a second pick-lifting cylinder 308. The output end of the first pick-lifting cylinder 306 is rotatably connected to a large pick arm 307; the output end of the second pick-lifting cylinder 308 is rotatably connected to a small pick arm 309. The large pick arm 307 and the small pick arm 309 are rotatably connected to the pick arm 301 via a rotating shaft to provide the excitation force and clamping force required for tamping. The first lifting cylinder 306 and the large pick arm 307 work together to provide the main tamping force, while the second lifting cylinder 308 and the small pick arm 309 work together to provide auxiliary tamping force. The two work together to meet the tamping needs under different working conditions.

[0045] like Figure 5 As shown, a tamping screw 303 is movably inserted into the tamping arm 301. One end of the tamping screw 303 passes through the lug 104 and extends to the outside of the tamping arm 301. A nut 304 is threaded onto one end of the tamping screw 303 for mounting the tamping arm 301 onto the lug 104. Copper sleeves 305 are rotatably fitted onto both ends of the outer surface of the tamping screw 303, and the copper sleeves 305 are located inside the lug 104. By passing the tamping screw 303 through the lug 104 and the tamping arm 301, and securing it with the nut 304, the tamping arm 301 can be quickly and easily mounted onto the lug 104. This not only improves the assembly efficiency of the tamping device but also facilitates subsequent maintenance and disassembly, reducing maintenance costs and time.
