Description

Technical Field

[0001] This utility model belongs to the technical field of railway maintenance equipment, specifically, it relates to a device for the maintenance and repair of railway track beds. Background Technology

[0002] Ballasted track, as an important form of track structure, uses a stone ballast bed structure as its foundation, which has advantages such as excellent elasticity, convenient maintenance and replacement, excellent acoustic absorption performance, and significant vibration attenuation. However, ballast particles can break down under the influence of precipitation erosion and humidity changes. The resulting fine powder, along with soil particles mixed in during construction, forms composite pollutants through adhesion. These pollutants fill the structural voids between the ballast particles, forming a water-blocking layer, which in turn leads to drainage system failure, foundation frost heave, mud surge, and other defects. Ultimately, this results in engineering problems such as ballast bed structural hardening, degradation of elasticity, and deterioration of vibration damping function. Therefore, regular cleaning of the ballast is necessary.

[0003] Currently, the existing technology involves first having the main body of the cleaning and screening machine travel along the track, using its assembled rake tooth mechanism to remove the ballast under the sleepers, then using a bucket device with screening function to classify the collected ballast, and finally backfilling the ballast that meets the specifications into the space under the sleepers.

[0004] However, during the above processing, when a large number of caking blocks need to be processed centrally, the existing equipment cannot achieve timely and effective crushing and separation, resulting in the accumulation and blockage of ballast and caking blocks at the screen, which significantly reduces the screening efficiency.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0008] Furthermore, the pretreatment facility includes: The box has open structures on its adjacent two side walls, with one side wall facing the rake tooth mechanism and the other side wall facing the screening mechanism. The collection plate is located inside the box and moves vertically.

[0009] Furthermore, the first vibrating element is the exciter.

[0010] Furthermore, the collecting plate is provided with a first guide part, which is arranged in the direction close to the rake tooth mechanism and is inclined in the horizontal direction towards the ground.

[0014] Furthermore, the rake teeth are set to be multiple, and the multiple rake teeth are set to wrap around the timing belt once.

[0015] Furthermore, the screening mechanism includes: Screening components, including: The collection box is connected to the connector and is located away from the rake tooth mechanism, with an open structure at the top; The screening box is located above the collection box and has through holes.

At the same time, the pretreated ballast is effectively separated, significantly reducing the load on the screening mechanism. Through the synergistic effect of the pretreatment mechanism and the screening mechanism, screening efficiency is improved while ensuring screening accuracy. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 6 As shown, this utility model provides a device for railway track bed maintenance and repair, including a connector 1, a rake tooth mechanism 2, a pretreatment mechanism 3, and a screening mechanism 4. The connector 1 is connected to a moving mechanism, the rake tooth mechanism 2 is connected to the connector 1, and is used to clean the ballast under the sleepers; the pretreatment mechanism 3 is connected to the connector 1, and is used to break up the slabs in the ballast; the screening mechanism 4 is connected to the connector 1, and is used to separate the ballast after being treated by the pretreatment mechanism 3.

[0024] It should be noted that the moving mechanism (not shown in the figure) includes a chassis, a power unit, a pair of tracks, a boom, and a forearm. The power unit is mounted on the chassis, and the pair of tracks are located on both sides of the chassis and are driven by the power unit. One end of the boom is connected to the chassis, and the other end is connected to the forearm. Both the boom and forearm are equipped with hydraulic cylinders, which drive the boom and forearm to rotate.

[0025] When in use, the power unit is started, which drives the tracks to rotate. The tracks then drive the main body of the device to travel onto the rails and move along the rails.

[0026] For example, the connector 1 may be, but is not limited to, a plate-like structure or a shell-like structure. The connector 1 is rotatably connected to the forearm, and the connecting plate is rotatably connected to the hydraulic cylinder on the forearm.

[0027] For example, such as Figures 1 to 2 As shown, the connector 1 is a rectangular plate structure, and the rake tooth mechanism 2 includes a pair of fixed plates 21, a pair of pulleys 22, a synchronous belt 23, rake teeth 24, and a motor 25. The pair of fixed plates 21 are arranged vertically opposite each other and connected by a fastener (not shown in the figure). The fixed plates 21 are rectangular plate structures, and the length direction of the fixed plates 21 is parallel to the length direction of the connector 1. One end of the upper fixed plate 21 is fixedly connected to one end of the connector 1.

[0028] The motor 25 is fixedly mounted on the top surface of the upper fixing plate 21. The motor 25 is located between the connecting piece 1 and the fixing plate 21. The motor 25 is enclosed by a cover 11, and both ends of the cover 11 are fixedly connected to the connecting piece 1 and the fixing plate 21, respectively. The output shaft of the motor 25 passes through the fixing plate 21 and is fixedly connected to the pulley 22.

[0029] A pair of pulleys 22 are rotatably mounted on both ends of a fixed plate 21 and located between the two fixed plates 21. A timing belt 23 is fitted onto the pair of pulleys 22, and the inner side of the timing belt 23 is engaged with the pulleys 22, forming a relatively sealed space between the belt and the fixed plate 21.

[0030] Optionally, multiple rake teeth 24 are configured, with multiple rake teeth 24 arranged to wrap around the timing belt 23 one revolution.

[0031] For example, such as Figure 2 As shown, multiple rake teeth 24 are evenly spaced around the synchronous belt 23, and the rake teeth 24 are fixedly connected to the synchronous belt 23.

[0032] Through the above embodiments, when the device moves along the track by driving the track with a power device, the motor 25 drives the pulley 22 to rotate, so that the synchronous belt 23 can drive multiple rake teeth 24 to work in a cycle, and efficiently clean the ballast under the sleepers; and when the ballast is transported to the pretreatment mechanism 3, the exciter drives the collection plate 32 to generate high-frequency vibration, which can effectively break up the slab blocks in the ballast, avoid accumulation and blockage of the screening mechanism 4, and further improve the screening efficiency; the pretreated ballast can quickly complete the grading and separation when it enters the screening mechanism 4, and improve the screening efficiency while ensuring the screening accuracy.

[0033] According to the example embodiment, such as Figures 1 to 3 As shown, the pretreatment mechanism 3 includes a housing 31, a collecting plate 32, and a first vibrating element 33. The adjacent side walls of the housing 31 are open structures, with one side wall facing the rake mechanism 2 and the other side wall facing the screening mechanism 4. The collecting plate 32 is located inside the housing 31 and moves vertically. The first vibrating element 33 is connected to the bottom wall of the housing 31 and the collecting plate 32, and is used to drive the collecting plate 32 to vibrate.

[0034] For example, the horizontal cross-section of the box 31 includes, but is not limited to, a rectangle or a quarter sector. The top wall and the adjacent side walls of the box 31 are open structures. One side wall A is set in the direction of the rake teeth 24, and the other side wall B is set perpendicular to the side wall A and in the direction of the screening mechanism 4.

[0035] It should be noted that the side wall opposite to side wall A of box 31 is side wall C, and the side wall opposite to side wall B of box 31 is side wall D.

[0036] The collecting plate 32 is, but is not limited to, a rectangular plate structure or a quarter-sector plate structure, and is adapted to the box body 31. Preferably, the collecting plate 32 is provided with a baffle 421, which is perpendicular to the collecting plate 32 and is located near the side wall C and side wall D of the box body 31. Further, the height of the baffle 421 is lower than the height of the box body 31.

[0037] Optionally, the first vibrating element 33 is an exciter. Further, a spring 414 can be provided between the collecting plate 32 and the bottom wall of the box 31, with one end connected to the bottom wall of the box 31 and the other end connected to the collecting plate 32, for driving the collecting plate 32 to move away from the bottom wall of the box 31.

[0038] For example, such as Figures 2 to 5 As shown, the horizontal cross-section of the box 31 is rectangular, and the top wall and adjacent side walls of the box 31 are open structures. The box 31 is bolted to the connector 1. Side wall A is oriented towards the rake teeth 24, side wall B is perpendicular to side wall A and oriented towards the screening mechanism 4. Side wall C is opposite to side wall A, and side wall D is opposite to side wall B. The collecting plate 32 is a rectangular plate structure and is adapted to the box 31. The collecting plate 32 is provided with a baffle 421, which is perpendicular to the collecting plate 32 and is located near side walls C and D of the box 31.

[0039] The collection plate 32 is provided with a first guide part 321. The first guide part 321 is fixedly connected to the edge of the collection plate 32 near the side wall A and is inclined in the horizontal direction towards the ground. The first guide part 321 is a plate-shaped structure and extends to the outside of the box 31.

[0040] The collecting plate 32 is provided with a second guide portion 322, which is adjacent to and connected to the first guide portion 321, and is inclined in the horizontal direction towards the ground. The second guide portion 322 is fixedly connected to the edge of the collecting plate 32 near the side wall B. The second guide portion 322 is a plate-shaped structure and extends to the outside of the box body 31. The second guide portion 322 is provided with multiple blocking ribs 3221, which are spaced apart along the inclined direction of the second guide portion 322.

[0041] Through the above embodiments, the present invention uses a first guide part 321 to quickly guide the ballast cleaned by the rake tooth mechanism 2 to the collection plate 32 of the box body 31 at an inclined angle. After the ballast cleaned by the rake tooth mechanism 2 enters the box body 31 through the side wall A, the first vibrating member 33 drives the collection plate 32 to generate high-frequency vibration, so that the slab block is broken in the box body 31. The broken ballast is discharged by the second guide part 322, and the flow rate of the ballast is further controlled by the spaced blocking ribs 3221 to prevent the screening mechanism 4 from being overloaded due to excessive conveying speed.

[0042] According to the example embodiment, such as Figures 1 to 6 As shown, the screening mechanism 4 includes a screening component 41 and a transport component 42. One end of the transport component 42 is located near the second guide part 322, and the other end is located above the screening box 412. It is used to transport the pre-treated ballast into the screening box 412 for separation processing.

[0043] For example, such as Figures 1 to 6 As shown, the transport component 42 includes a pair of baffles 421, two pairs of sprockets 422, and a chain belt 423. The connector 1 is provided with a mounting port 12, which is located on the end of the connector 1 away from the cover 11. The pair of baffles 421 are located inside the mounting port 12 and are positioned opposite each other. The fixing plate 21 is fixedly connected to the connector 1 and is inclined.

[0044] Two pairs of sprockets 422 are rotatably mounted on both ends of the fixed plate 21. Each pair of sprockets 422 has two sprockets, which are arranged opposite each other and fixedly connected by a coupling shaft 424. A chain belt 423 is sleeved on the sprockets 422 and meshes with them for transmission. The lead end of the chain belt 423 is located near the second guide part 322. The sprockets 422 are driven by a motor 25 (not shown in the figure), which is fixedly connected to the connector 1 and to one of the coupling shafts 424.

[0045] The chain conveyor 423 is provided with multiple receiving plates 425, which are distributed at intervals around the chain conveyor 423. The receiving plates 425 are arc-shaped plate structures and are located near the second guide section 322 to receive the ballast on the second guide section 322. The baffle 421 is located higher than the receiving plates 425.

[0046] For example, such as Figures 1 to 6 As shown, the screening assembly 41 includes a collection box 411, a screening box 412, a connecting column 413, a spring 414, and a second vibrating element 415. The collection box 411 is a rectangular box-shaped structure with an open top wall E and a side wall F. The collection box 411 is located below the lead-out end of the chain belt 423 and is fixedly connected to the connecting element 1. The side wall F of the collection box 411 is located away from the rake teeth 24, and the bottom wall of the collection box 411 can be raised and tilted towards the side wall F.

[0047] The screening box 412 is a rectangular box-shaped structure located above the collection box 411. The top wall of the screening box 412 is open, and the bottom wall has multiple through holes arranged in a rectangular array. One side wall G of the screening box 412 is open and faces away from the chain belt 423.

[0048] Four connecting columns 413 are provided, each located at the apex of the collection box 411. One end of each connecting column 413 is fixedly connected to the collection box 411, and the other end is slidably connected to the limiting groove 4121 at the bottom of the screening box 412. The number of springs 414 corresponds one-to-one with the number of connecting columns 413. One end of each spring 414 is fixedly connected to the bottom of the screening box 412, and the other end is fixedly connected to the collection box 411. The springs 414 are used to drive the screening box 412 to move away from the collection box 411. The second vibrating element 415 is a vibrator, which is fixedly connected to one side wall of the screening box 412.

[0049] Through the above embodiments, this utility model uses the cooperation of sprocket 422 and chain belt 423. The chain belt 423 drives the receiving plate 425 to receive the ballast at an inclined angle and transport it into the screening box 412. The screening box 412 generates high-frequency vibration under the drive of the second vibrating member 415. In cooperation with the spring 414 and connecting column 413, the ballast is graded and separated through the bottom through hole. Large ballast particles that meet the specifications are discharged from the side wall G of the screening box 412, and small ballast particles are discharged from the side wall F of the collection box 411. While improving screening efficiency, it significantly reduces the vibration noise during equipment operation.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
