Description
Technical Field
[0001] The utility model belongs to the technical field of railway ballast bed maintenance. Specifically, it relates to a vibrating device for railway ballast beds. Background Art
[0002] Under the long-term rolling pressure of trains on the rails, the rails transfer the rolling pressure received to the sleepers below them. As a result, the sleepers are continuously driven by external forces and are in a state of vibration, swaying, etc. over a long period. Consequently, the crushed stones and the like laid under the sleepers are gradually displaced, causing the situation where the lower part of the sleepers is suspended or the sleepers sink. In this way, when a train passes over such sleepers, the sleepers will experience a large vibration. On the one hand, this causes the amplitude of the rails to increase accordingly, leading to rail deformation or rail breakage, and extremely prone to safety accidents. On the other hand, the sleepers with large vibrations are extremely likely to break, causing the rails connected to them to bend inward, outward, or upward, and also inevitably causing safety accidents. Therefore, there is an urgent need for a railway maintenance device to refill the crushed stones under the sleepers to the lower part of the sleepers, so that the sleepers will not experience large fluctuations after being stressed, ensuring the safe operation of trains.

Specific implementation manners
[0026] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.
[0027] The present utility model discloses a vibrating device for railway ballast beds, as Figure 1-7As shown in the figure, it includes a transverse beam 600, at least two lifting cylinders 800 and a plurality of expandable and contractible surface vibrating mechanisms 200. These expandable and contractible surface vibrating mechanisms 200 are arranged at intervals along the length direction of the transverse beam 600. Each expandable and contractible surface vibrating mechanism 200 is arranged below the transverse beam 600. A guide rail is constructed at the lower end of the transverse beam 600. The guide rail extends along the length direction of the transverse beam 600 to both ends of the transverse beam 600. A plurality of linear motors 700 are assembled at intervals along the length direction of the guide rail. The number of linear motors 700 is the same as the number of expandable and contractible surface vibrating mechanisms 200. In the present invention, the number of lifting cylinders 800 is the same as the number of expandable and contractible surface vibrating mechanisms 200. Each lifting cylinder 800 is installed between the corresponding expandable and contractible surface vibrating mechanism 200 and the corresponding linear motor 700. The transverse beam 600 is connected to the walking vehicle. Or the number of lifting cylinders 800 is two. The two lifting cylinders 800 are respectively installed on both sides of the upper end of the transverse beam 600, and each lifting cylinder 800 is connected to the walking vehicle. Each expandable and contractible surface vibrating mechanism 200 and the corresponding linear motor 700 are fixedly connected. The working principle and advantages of the present invention are as follows: The function of the lifting cylinder 800 of the present invention is to directly or indirectly drive the expandable and contractible surface vibrating mechanism 200 to move in the vertical direction, so that the lower end of the expandable and contractible surface vibrating mechanism 200 is inserted into the ballast at the front and rear ends of the sleeper. During the insertion process or after insertion, control the expandable and contractible surface vibrating mechanism 200 to act, so that it gradually closes, and then gradually gather the ballast covered by the expandable and contractible surface vibrating mechanism 200 towards the bottom of the sleeper, accompanied by slight vibration, so that the bottom of the sleeper is quickly filled and compacted. The present invention can also control the expandable and contractible surface vibrating mechanism 200 to gradually expand along the length direction of the sleeper, so as to increase the vibrating area of the expandable and contractible surface vibrating mechanism 200 and achieve the purpose of improving the vibrating efficiency. The present invention can realize the purpose of vibrating and filling the ballast at different positions of the sleeper by the expandable and contractible surface vibrating mechanism 200 by controlling the linear motor 700 to move along the length direction of the sleeper, improving the mobility of the operation. Moreover, the cross beam of the present invention is generally installed on the walking vehicle, and the walking vehicle travels beside the railway rather than on the rail. Therefore, the rail will not be subjected to a downward pressure. In this way, during the gradual closing process of the expandable and contractible surface vibrating mechanism 200, the upward force of the ballast is sufficient to lift the sleeper and the rail upward by a small distance, without using a rail-lifting device to lift the rail and then vibrate, achieving the purpose of reducing the operation difficulty. In summary, the present invention can effectively refill the ballast under the sleeper to the lower part of the sleeper, so that the sleeper will not have large fluctuations after being stressed, ensuring the safe operation of the train.
[0028] As a preferred embodiment of the present invention, as Figure 3 、 4As shown, the folding and expanding surface vibrating mechanism 200 includes vibrating arms 201 symmetrically arranged on both sides of the assembly seat 100. The sleeper is located between the two vibrating arms 201. The middle of each vibrating arm 201 is hinged to the assembly seat 100. The upper end of the vibrating arm 201 is hinged to one end of the driving arm 500, and the other end of the driving arm 500 is hinged to the middle of the assembly seat 100. An opening and closing vibrating claw is assembled at the lower end of the vibrating arm 201. In this embodiment, the two driving arms 500 synchronously drive the upper ends of the two vibrating arms 201 to move away from each other. Since the middle of the vibrating arm 201 is hinged to the assembly seat 100, the lower ends of the two vibrating arms 201 move closer to each other, and further the opening and closing vibrating claws move closer to each other, thereby gradually gathering the crushed stones on the outer side of the lower part of the sleeper directly below the sleeper, achieving the purpose of filling the bottom of the sleeper. When the filling is completed, the two driving arms 500 are controlled to drive the two vibrating arms 201 to gradually return to their original positions. In this embodiment, in order to achieve the purpose of vibrating the vibrating claws gradually driven by the vibrating arm 201 during the process of gathering the crushed stones to the bottom of the sleeper, so that the crushed stones are gradually compacted during the gathering process to avoid the situation of crushed stone collapse due to the appearance of pores, the measures taken are as Figure 5 , 6 As shown, the mutually approaching ends of the two driving arms 500 in this embodiment are connected by a crankshaft. The crankshaft is rotatably connected to the assembly seat 100 and is coaxially connected to the output shaft of a hydraulic motor 300 installed on the assembly seat 100. A first hinge shaft 206 is fixed to the upper part of the vibrating arm 201. The crankshaft of this embodiment includes a first shaft rod 401. Fixed seats 402 are constructed at both ends of the first shaft rod 401. A second shaft rod 403 is fixed to each fixed seat 402. The axis of the second shaft rod 403 is parallel (but not coincident) with the axis of the first shaft rod 401, and the axes of these two second shaft rods 403 coincide. Each second shaft rod 403 is rotatably connected to the corresponding side of the assembly seat 100. The driving arm 500 in this embodiment is a driving oil cylinder 501. First hinge rings 502 and second hinge rings 503 are respectively constructed at both ends of the driving oil cylinder 501. The first hinge rings 502 and the second hinge rings 503 are respectively movably sleeved on the first shaft rod 401 and the first hinge shaft 206. The working principle and advantages of this embodiment are as follows: In this embodiment, the hydraulic motor 300 drives the first shaft rod 401 to rotate, and then the second shaft rod 403 makes an eccentric motion. Thus, the driving oil cylinder 501 is driven to reciprocate through the first hinge ring 502. In this way, the purpose of driving the driving oil cylinder 501 to drive the vibrating arm 201 to reciprocate is achieved, and the effect of vibrating the crushed stones by the vibrating claws is achieved.
[0029] As a preferred embodiment of the present invention, as Figure 3As shown, the assembly base 100 includes a base body 101. At the lower end of the base body 101, a receiving body 102 is constructed. On both sides of the receiving body 102, two connecting arms 103 are symmetrically constructed. Each vibrating arm 201 is hinged to the corresponding connecting arm 103. The above hydraulic motor 300 is assembled on the receiving body 102. As Figure 1 shown, in this embodiment, a transmission assembly 400 is constructed between the assembly base 100 and the two vibrating arms 201. The transmission assembly 400 is in transmission connection with the hydraulic motor 300, and the transmission assembly 400 is in transmission connection with each opening and closing vibrating claw. As Figure 4 、 5 shown, the vibrating arm 201 is hinged to the assembly base 100 through a second hinge shaft 408, and the second hinge shaft 408 is rotatably connected to the assembly base 100. The transmission assembly 400 of this embodiment includes a rotating shaft 405 assembled on the assembly base 100. A first sprocket 407 is assembled on the rotating shaft 405. A second sprocket 409 is assembled on each second hinge shaft 408. The first sprocket 407 and the two second sprockets 409 are in transmission connection through a transmission chain 410. A first gear 404 and a second gear 406 are respectively installed on the second shaft rod 403 and the rotating shaft 405. The first gear 404 and the second gear 406 mesh with each other, and the radius of the first gear 404 is smaller than the radius of the second gear 406. The working principle and advantages of this embodiment are as follows: In the process of controlling the operation of the hydraulic motor 300 in this embodiment, the second shaft rod 403 drives the first shaft rod 401 to perform an eccentric motion. At the same time, the second shaft rod 403 drives the first gear 404 to rotate. During the rotation of the first gear 404, it drives the second hinge shaft 408 to rotate, so that the two second hinge shafts 408 synchronously drive the two opening and closing vibrating claws to open, thereby increasing the vibrating area. Subsequently, with the downward drive of the lifting oil cylinder 800, the opening and closing vibrating claws gradually extend into the crushed stones. Along with the vibration, the lower ends of the two vibrating arms 201 gradually approach, achieving the purpose of repairing the sleeper.
[0030] As a preferred embodiment of the present utility model, as Figure 7As shown in the figure, the opening and closing vibrating claws include first vibrating claws 202 constructed on both sides of the lower end of the vibrating arm 201. At one end of each first vibrating claw 202 along the transverse direction of the sleeper, a second vibrating claw 203 is provided. The second vibrating claw 203 is close to the first vibrating claw 202. On the side of the upper end of the second vibrating claw 203 close to the vibrating arm 201, a threaded transmission sleeve 205 is constructed. At both ends of the second hinge shaft 408, threaded transmission rods 411 are respectively constructed. The thread directions of these two threaded transmission rods 411 are opposite. Each threaded transmission sleeve 205 is sleeved outside the corresponding threaded transmission rod 411, and the threaded transmission sleeve 205 is threadedly connected to the threaded transmission rod 411. In this embodiment, through the transmission of the transmission component 400, the second hinge shaft 408 rotates. During the rotation of the second hinge shaft 408, the two threaded transmission rods 411 on it rotate, thereby driving the two threaded transmission sleeves 205 to approach or move away from each other, achieving the purpose of changing the vibrating area while vibrating. In this embodiment, a plurality of vibrating teeth 204 are respectively constructed on the lower parts of each first vibrating claw 202 and the second vibrating claw 203. The vibrating teeth 204 on the first vibrating claw 202 and the second vibrating claw 203 are all arranged at intervals along the length direction of the sleeper. The purpose of using the vibrating teeth 204 in this embodiment is that these vibrating teeth 204 can fully prevent the vibrated crushed stones from moving transversely along the first vibrating claw 202 or the second vibrating claw 203, preventing the vibrated crushed stones from leaving the grasping range of the opening and closing vibrating claws, and thus avoiding affecting the vibrating effect. In order to facilitate the first vibrating claw 202 and the second vibrating claw 203 to be smoothly inserted into the crushed stone bed, the measures taken are that the end faces of the mutually separated ends of the first vibrating claw 202 and the second vibrating claw 203 are both inclined surfaces, and these two inclined surfaces gradually approach downward in the vertical direction. The function of the inclined surface is to ensure that the first vibrating claw 202 and the second vibrating claw 203 are smoothly inserted into the crushed stone bed; the end faces of the mutually close ends of the first vibrating claw 202 and the second vibrating claw 203 are both vertical planes, and these two vertical planes are close to or fit with each other. The purpose is to facilitate the movement of the second vibrating claw 203 along the vertical plane of the first vibrating claw 202, serving the purpose of restricting the second vibrating claw 203. And when the second vibrating claw 203 bears a large external force, the first vibrating claw 202 can share part of the external force, enabling the second vibrating claw 203 to have a high anti-external force ability.
