Technical Field

[0001] This utility model relates to the field of railway construction technology, and in particular to a bridge and tunnel cleaning and screening device. Background Technology

[0002] Bridge and tunnel cleaning and screening devices are key equipment for railway line maintenance. They are mainly used to remove dirt, gravel, weeds, and other debris from the track bed, while also screening and recycling reusable ballast. Their core function is to restore the elasticity and drainage performance of the track bed, extend the service life of the track, and ensure safe train operation.

[0003] The railway ballast layer serves to support the track and aids in drainage. Larger-diameter ballast effectively supports the track, ensuring its stability. However, smaller-diameter waste ballast can lead to unevenness in the ballast layer, affecting track stability and even causing settlement and deformation. Therefore, effectively separating waste ballast from backfillable ballast ensures the stability of the track structure. Utility Model Content

[0004] This invention provides a bridge and tunnel cleaning and screening device that can effectively separate waste ballast.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge and tunnel cleaning and screening device, comprising a base frame, a transport component, and a screening component. The base frame has pairs of steel wheels at both ends of its bottom. The transport component is positioned above the base frame and includes two symmetrically arranged upper and lower belt conveyors. The two upper belt conveyors are respectively positioned on both sides of the base frame. The lower belt conveyor is located between and below the two upper belt conveyors. The screening component is located horizontally between the two upper belt conveyors and vertically between the upper and lower belt conveyors.

[0006] Preferably, a connecting beam is fixed on the support frame, and a pair of steel wheels are provided at both ends of the bottom of the base frame. The pair of steel wheels are rotatably connected to the base frame through a rotating shaft.

[0007] Preferably, the lower end of the collecting hopper is provided with an opening, and the two lower belt conveyors are located below the opening and correspond one-to-one with the two collecting hoppers.

[0009] Preferably, the sieve plate has sieve holes.

[0010] Preferably, one end of the spring buffer is fixed to the inner frame, and the other end of the spring buffer is fixed to the sieve plate, and a vibration motor is fixedly connected to the sieve plate.

[0011] Preferably, the feed hopper is located below the upper belt conveyor, and the feed hopper is rotatably connected to the support frame.

[0012] Preferably, two strips are fixedly connected to the panel of the sieve plate, and a wing plate is fixedly connected to the lower side of the sieve plate panel, the wing plate being bent downwards.

[0013] Preferably, a rear plate is provided on the raised end side of the lower belt conveyor, the rear plate is fixed on the base frame, the upper surface of the rear plate is lower than the raised end of the lower belt conveyor, and a lifting component is provided on the rear plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. After the track machine moves onto the railway track, the bridge and tunnel cleaning and screening device can be lifted and its position controlled by the mechanical boom installed on the track machine. The bridge and tunnel cleaning and screening device is placed on the rail, and the upper and lower belt conveyors are driven by the motor. The vibrating motor can make the screen plate vibrate. The cleaned ballast is first transported to the transmission belt of the upper belt conveyor and moves upward to the screen plate. It is thrown out from the high end of the upper belt conveyor. The feed hopper can accurately receive the ballast thrown out from the end of the upper belt conveyor. After the ballast falls into the feed hopper, it is collected in the feed hopper and then falls onto the vibrating screen plate. The screen plate has screen holes of a specific diameter. Ballast with a particle size larger than the screen hole diameter is guided downward to the track through the wing plate, and ballast with a particle size smaller than the screen hole diameter falls into the collection hopper below.

[0017] 2. The material falls from the hopper onto the transmission belt of the lower belt conveyor and moves upward. It is then ejected from the high end of the lower belt conveyor and enters the collection bag. Once the collection bag is full of ballast, the operator can use an electric hoist to lift the collection bag and place it on the platform on both sides of the track by controlling the lifting device, thus completing the screening work.

[0026] 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 scope of protection of the present utility model.

[0027] This utility model provides a bridge and tunnel cleaning and screening device, such as Figure 1 and Figure 2 As shown, the device includes a base frame 1, a transport assembly, and a screening assembly. The bridge and tunnel cleaning and screening device works in conjunction with the ballast removal device. The ballast removal device throws the excavated ballast onto the bridge and tunnel cleaning and screening device, which then screens ballast that does not meet the particle size requirement. The bridge and tunnel cleaning and screening device is driven forward by a track machine, which is equipped with a mechanical boom. The bridge and tunnel cleaning and screening device is fixed on the mechanical boom, which can lift and place the device on the rails.

[0028] like Figure 1 and Figure 2 As shown, the transport assembly is located above the base frame 1. The transport assembly includes two symmetrically arranged upper belt conveyors 5 and lower belt conveyors 7. The two upper belt conveyors 5 are respectively located on both sides of the base frame 1, and the lower belt conveyors 7 are located between and below the two upper belt conveyors 5. A support frame 11 is fixedly connected to the upper end of the base frame 1. The upper surface of the support frame 11 is inclined, and a connecting beam 12 is fixed on the support frame 11. The support frame 11 is fixed to the mechanical boom of the track machine through the connecting beam 12. The two sets of upper belt conveyors 5 are symmetrically arranged on both sides of the support frame 11, which can improve the efficiency of transporting ballast to the screen plate 3. The two sets of lower belt conveyors 7 are located inside the support frame 11 and below the upper belt conveyors 5. Both the upper belt conveyors 5 and the lower belt conveyors 7 are driven by motors to move the belts, realizing the transport of ballast.

[0029] One or two lower belt conveyors 7 can be set. When there is only one lower belt conveyor 7, a wider belt conveyor is selected. When there are two lower belt conveyors 7, a narrower belt conveyor is selected, and the two lower belt conveyors 7 are arranged symmetrically.

[0030] like Figure 4 As shown, an inner frame 2 is fixedly connected to the upper surface of the support frame 11. The screening component is located horizontally between the two upper belt conveyors 5 and vertically between the upper belt conveyor 5 and the lower belt conveyor 7. The screening component includes a collection hopper 21 and a screen plate 3. The two collection hoppers 21 are arranged horizontally and fixed inside the inner frame 2. The lower end of the collection hopper 21 is provided with an opening. The two lower belt conveyors 7 are located below the opening and correspond one-to-one with the two collection hoppers 21. The peripheral sidewalls of the collection hopper 21 are all inclined. The screen plate 3 is inclined towards the opening and is set above the hopper 21. The screen plate 3 is inclined and the inclination direction of the screen plate 3 is consistent with the inclination direction of the upper surface of the support frame 11. The inclination directions of the upper belt conveyor 5 and the lower belt conveyor 7 are consistent. The inclination direction of the upper belt conveyor 5 is consistent with that of the screen plate 3. A spring buffer 22 is fixed between the screen plate 3 and the inner frame 2. One end of the spring buffer 22 is fixed on the inner frame 2, and the other end of the spring buffer 22 is fixed on the screen plate 3. A vibration motor 4 is fixedly connected to the screen plate 3.

[0031] The ballast removed by the ballast removal device is first transported to the transmission belt of the upper belt conveyor 5 and moved above the screen plate 3, and then thrown out from the high end of the upper belt conveyor 5.

[0032] like Figure 3As shown, feed hoppers 6 are installed on both sides of the high-positioned side of the screen plate 3, and feed hoppers 6 are located below the upper belt conveyor 5. The feed hoppers 6 are rotatably connected to the support frame 11. Starting the vibration motor 4 causes the screen plate 3 to vibrate, while the spring buffer 22 continuously reciprocates between extension and contraction, increasing the amplitude of the screen plate 3. Rotating the feed hoppers 6 adjusts their orientation, allowing them to more accurately receive the ballast ejected from the end of the upper belt conveyor 5. After falling into the feed hoppers 6, the ballast is collected and then falls onto the vibrating screen plate 3, as shown. Figure 2 As shown, the sieve plate 3 has sieve holes of a specific diameter. Barrel particles smaller than the sieve hole diameter fall into the collection hopper 21 below, and from there onto the conveyor belt of the lower belt conveyor 7, moving upwards and being ejected from the higher end of the lower belt conveyor 7. Two strips 31 are fixedly connected to the panel of the sieve plate 3, arranged in a "V" shape. A wing plate 32 is fixedly connected to the lower side of the sieve plate 3 panel, with the two ends of the two strips 31 furthest apart being close to the wing plate 32. When the barrel passes through the "V"-shaped strips 31, the flow trajectory of the barrel changes due to the angle and position of the two strips 31, allowing it to pass through the sieve plate 3 more evenly, increasing the material contact area during screening, and thus improving screening efficiency. Figure 5 As shown, the wing plate 32 bends downward to guide the flow of ballast particles larger than the sieve aperture onto the track.

[0033] Ballast with a particle size larger than the sieve aperture meets the requirements for ballast laying in railway tracks. Ballast with a suitable particle size can provide a uniform and solid foundation, enabling the entire track to better withstand the load from the train and preventing problems such as subsidence and uneven settlement.

[0034] like Figure 3 and Figure 6 As shown, the bottom of the base frame 1 is equipped with pairs of steel wheels 14 at both ends. The pairs of steel wheels 14 are rotatably connected to the base frame 1 via a rotating shaft. The distance between the same pair of steel wheels 14 is the same as the distance between two parallel steel rails of a railway track. When the base frame 1 is placed on the rail, the steel wheels 14 can slide on the rail.

[0035] like Figure 7As shown, a rear plate 13 is provided on one side of the raised end of the lower belt conveyor 7. The rear plate 13 is fixed to the base frame 1. The upper surface of the rear plate 13 is lower than the raised end of the lower belt conveyor 7. A lifting component 8 is provided on the rear plate 13. The lifting component 8 includes a support column 81, a rotating rod 82, a rotating rod 83, and an electric hoist 84. The support column 81 is fixed to the rear plate 13. The rotating rod 82 is rotatably connected to the support column 81. The rotating rod 83 is rotatably connected to the rotating rod 82. At the free end of 2, the electric hoist 84 is mounted on the rotating rod 83. By rotating the rotating rod 82 and the rotating rod 83, the electric hoist 84 can be moved horizontally. A storage bag is placed on the rear plate 13. The ballast thrown from the high end of the lower belt conveyor 7 enters the storage bag. After the storage bag is full of ballast, the operator can use the electric hoist 84 to lift the storage bag. By controlling and adjusting the lifting device 8, the storage bag is placed on the platform on both sides of the track.

[0036] Using this utility model, such as Figure 1 and Figure 2 As shown, after the track machine moves onto the railway track, the mechanical boom installed on the track machine can lift and control the position of the bridge and tunnel cleaning device. The device is then placed on the rails, and the upper belt conveyor 5 and lower belt conveyor 7 are driven by a motor. Starting the vibrating motor 4 causes the screen plate 3 to vibrate. The cleaned ballast is first transported to the transmission belt of the upper belt conveyor 5 and moves upwards towards the screen plate 3, then is thrown out from the high end of the upper belt conveyor 5. The feed hopper 6 accurately receives the ballast thrown from the end of the upper belt conveyor 5. After the ballast falls into the feed hopper 6... After being collected in the feed hopper 6, the ballast falls onto the vibrating screen plate 3. The screen plate 3 has screen holes of a specific diameter. Ballast particles larger than the screen hole diameter are guided downwards onto the track through the wing plate 32, while ballast particles smaller than the screen hole diameter fall into the collection hopper 21 below. From the collection hopper 21, the ballast falls onto the transmission belt of the lower belt conveyor 7 and moves upwards. It is then ejected from the high end of the lower belt conveyor 7 and enters the collection bag. Once the collection bag is full of ballast, the operator can use the electric hoist 84 to lift the collection bag and, by controlling the lifting device 8, place the collection bag on the platform on both sides of the track to complete the screening work.

[0037] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
