Description

Technical Field

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

[0002] Bridge and tunnel cleaning and screening machines used in railway construction are mainly used to clean and screen ballast on railway track beds. Ballast plays a role in supporting and fixing the tracks in the railway track bed, effectively distributing track loads and preventing track subsidence or deformation. With railway use, ballast gradually wears down, and fine ballast particles may lose their original function, affecting the load-bearing capacity and stability of the track bed. Bridge and tunnel cleaning and screening machines can help remove fine, low-quality, or worn ballast, thereby ensuring the stability and load-bearing capacity of the track bed and ensuring the safety of railway operations.

[0003] A search revealed a Chinese patent with publication number "CN116971219A" that discloses "a multi-functional railway bridge and tunnel cleaning and screening machine." This application discloses that "the ballast stone cleaned by the rake teeth can be directly screened according to specifications and standards, and the ballast stone of different specifications can be separated and placed separately for subsequent processing, saving time and improving work efficiency." Although this device can transport the ballast stone dug from the bottom of the rails to the screening device for screening, the device needs to move inside the track. This means that its movement path is limited by the internal space of the track. In railway lines or curves with narrow spaces, the operation of the tracked vehicle will be more difficult, affecting the efficiency and flexibility of the operation. Utility Model Content

[0004] This utility model provides a bridge and tunnel cleaning and screening machine, which solves the problem mentioned in the background art that the operation of the tracked vehicle may be more difficult in narrow railway lines or curves, affecting the efficiency and flexibility of the operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bridge and tunnel cleaning and screening machine, comprising a traveling device and a bridge and tunnel cleaning and screening mechanism, wherein a lifting component for lifting the traveling device is provided at the bottom of the traveling device, and the bridge and tunnel cleaning and screening mechanism is connected and fixed on the traveling device.

[0006] Preferably, the lifting component includes two sets of rotatable frames disposed below the traveling device, the upper end of the traveling device is provided with multiple hydraulic arms, a connecting beam is disposed above the bridge and tunnel cleaning and screening mechanism, and the free ends of the multiple hydraulic arms are fixedly connected to the connecting beam.

[0007] Preferably, the two sets of the vehicle frame are located at the front and rear ends of the traveling device, respectively. The vehicle frame and the traveling device are rotatably connected. Rollers are rotatably connected to both sides of the vehicle frame. A pusher is provided between the vehicle frame and the traveling device.

[0008] Preferably, the bridge and tunnel cleaning and screening mechanism includes a base frame, a transport component, and a screening component. The transport component is disposed above the base frame and includes a feeding component for conveying ballast to the screening component and a discharging component for receiving and conveying waste ballast screened out by the screening component. The screening component is located between the feeding component and the discharging component, and the feeding component is located above the discharging component.

[0009] Preferably, a support frame is fixedly connected to the upper end of the base frame, and the connecting beam is fixed on the support frame.

[0010] Preferably, a slot is provided at the center of the upper surface of the connecting beam, and the end of the free end of the multi-segment hydraulic arm extends into the slot. The free end of the multi-segment hydraulic arm is bolted to the connecting beam.

[0011] Preferably, the screening assembly includes a hopper and a screen plate. An inner frame is fixedly connected to the upper surface of the support frame. Two hoppers are arranged laterally and fixed inside the inner frame. The screen plate is disposed above the hoppers. The screen plate is inclined, with the inclined surface of the screen plate facing away from the traveling device, and the highest side of the screen plate is close to the traveling device.

[0012] Preferably, a spring buffer is fixed between the sieve plate and the inner frame. 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. A vibration motor is fixedly connected to the sieve plate.

[0014] Preferably, a rear plate is fixedly connected to the base frame, and a lifting device for transferring waste ballast is provided on the rear plate.

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

[0016] 1. After the traveling device moves onto the railway track, the frame is placed on the rails so that the four rollers are on the rails. The pushers on the two sets of frames are activated to lift the entire traveling device off the sleepers. The tracks of the traveling device are removed from the railway track, and the rollers are driven to rotate by the drive unit. The traveling device moves on the rails through the rollers driven by the drive unit. The bridge and tunnel cleaning screen machine that runs directly on the rails can more flexibly cope with complex track layouts and working environments. It can turn, change tracks, and cross various track structures directly on the railway like a conventional railway vehicle. The operation is more flexible and reduces the space and path restrictions caused by track movement. The bridge and tunnel cleaning screen mechanism can be lifted and placed on the rails by the mechanical boom set on the traveling device.

[0017] 2. The upper and lower belt conveyors are driven by a motor. Starting the vibrating motor causes the screen plate to vibrate. The ballast removed by the ballast removal device is first transported to the upper belt conveyor and moves upwards towards the screen plate, where it is thrown out from the higher end of the upper belt conveyor. The feed hopper accurately catches the ballast thrown out from the end of the upper belt conveyor. After falling into the feed hopper, the ballast is collected and then falls onto the vibrating screen plate, which has specific... The sieve aperture allows ballast particles larger than the sieve aperture to flow downwards onto the track via the wing plates, while particles smaller than the sieve aperture fall into the collection hopper below. From there, they fall onto the transmission belt of the lower belt conveyor and move upwards, being ejected from the higher end of the lower belt conveyor and entering the collection bag. Once the collection bag is full of ballast, the operator can use an electric hoist to lift the bag and, by controlling the lifting mechanism, place it on the platform on either side of the track, completing the sieving process.

[0027] 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.

[0028] This utility model provides a bridge and tunnel cleaning and screening machine, such as Figure 1 and Figure 2 As shown, it includes a traveling device 1 and a bridge and tunnel cleaning and screening mechanism. The bottom of the traveling device 1 is provided with a lifting component for lifting the traveling device 1. The lifting component includes two sets of rotatable frames 11 symmetrically arranged below the traveling device 1. The two sets of frames 11 are located at the front and rear ends of the traveling device 1, respectively. The frames 11 are rotatably connected to the traveling device 1. Rollers 111 are rotatably connected to both sides of the frames 11. A pushing component 112 is provided between the frames 11 and the traveling device 1.

[0029] The pusher 112 can be a hydraulic pump, with the cylinder of the hydraulic pump rotatably connected to the traveling device 1 and the output shaft of the hydraulic pump rotatably connected to the frame 11. The upper end of the traveling device 1 is provided with a multi-segment hydraulic arm 12, and the free end of the multi-segment hydraulic arm 12 is provided with a bridge and tunnel cleaning mechanism. A connecting beam 15 is provided above the bridge and tunnel cleaning mechanism, and the free end of the multi-segment hydraulic arm 12 is fixedly connected to the connecting beam 15. After the traveling device 1 moves onto the railway track, the frame 11 is placed on the rail, so that the four rollers 111 are on the rail. The pushers 112 on the two sets of frames 11 are activated to lift the entire traveling device 1 off the sleepers. The track of the traveling device 1 is disengaged from the railway track, and the rollers 111 are driven to rotate by the drive. The traveling device 1 moves on the rail by the rollers 111 driven by the drive, which can prevent ballast from getting stuck in the gaps of the track when the track moves on the railway track. The distance between the two rollers 111 on the same set of frames 11 is the same as the distance between the two parallel rails of the railway track.

[0030] The bridge and tunnel cleaning and screening mechanism works in conjunction with the ballast removal device. The ballast removal device throws the excavated ballast onto the bridge and tunnel cleaning and screening mechanism, which then screens the ballast that does not meet the particle size requirement. The bridge and tunnel cleaning and screening mechanism is driven forward by the traveling device 1, which is equipped with a mechanical boom. The bridge and tunnel cleaning and screening mechanism is fixed on the mechanical boom, which can lift and place the bridge and tunnel cleaning and screening mechanism on the rails.

[0031] The driver can be a motor or engine, etc.

[0032] like Figure 3 and Figure 4 As shown, the bridge and tunnel cleaning and screening mechanism includes a base frame 13, a transport component, and a screening component. The transport component is located above the base frame 13. The transport component includes a feeding component for conveying ballast to the screening component and a discharging component for receiving and conveying waste ballast screened out by the screening component. The screening component is located between the feeding component and the discharging component, and the feeding component is located above the discharging component.

[0033] In this embodiment, both the loading and unloading components are conveyor belts, with the loading component being an upper conveyor belt 5 and the unloading component being a lower conveyor belt 7, and both the upper conveyor belt 5 and the lower conveyor belt 7 are provided in two sets.

[0034] A support frame 14 is fixedly connected to the upper end of the base frame 13. The upper surface of the support frame 14 is inclined. Two sets of upper belt conveyors 5 are symmetrically arranged on both sides of the support frame 14, which can improve the efficiency of transporting ballast to the screen plate 3. Two sets of lower belt conveyors 7 are arranged inside the support frame 14 and below the upper belt conveyors 5. A connecting beam 15 is fixed to the support frame 14. The connecting beam 15 is located inside the two sets of upper belt conveyors 5 and above the lower belt conveyors 7. A slot is opened at the center of the upper surface of the connecting beam 15. The free end of the multi-segment hydraulic arm 12 extends into the slot. The free end of the multi-segment hydraulic arm 12 is bolted to the connecting beam 15. Both the upper belt conveyor 5 and the lower belt conveyor 7 are driven by motors to move the belts and realize the transportation of ballast.

[0035] like Figure 6 and Figure 7As shown, an inner frame 2 is fixedly connected to the upper surface of the support frame 14. The screening assembly is located between two sets of upper belt conveyors 5. The screening assembly includes a collection hopper 21 and a screen plate 3. 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. 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 and tilted towards the opening. The screen plate 3 is set above the collection hopper 21. The screen plate 3 is inclined and set above the collection hopper 21. The sieve plate 3 is inclined, with the inclined surface of the sieve plate 3 facing away from the traveling device 1. The highest side of the sieve plate 3 is close to the traveling device 1. The inclination direction of the sieve plate 3 is consistent with the inclination direction of the upper surface of the support frame 14. 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 sieve plate 3. A spring buffer 22 is fixed between the sieve plate 3 and the inner frame 2. One end of the spring buffer 22 is fixed to the inner frame 2, and the other end of the spring buffer 22 is fixed to the sieve plate 3. A vibration motor 4 is fixedly connected to the sieve plate 3.

[0036] 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.

[0037] like Figure 1 and Figure 2 As shown, feed hoppers 6 are installed on both sides of the high-positioned side of the screen plate 3. The feed hoppers 6 are located below the upper belt conveyor 5 and are rotatably connected to the support frame 14. 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 the ballast falls into the feed hoppers 6, it is collected and then falls onto the vibrating screen plate 3. The screen plate 3 has screen holes of a specific diameter. Ballast particles smaller than the screen hole diameter fall into the collecting hopper 21 below, and from there onto the transmission belt of the lower belt conveyor 7, moving upwards and being ejected from the high end of the lower belt conveyor 7. Two strips are fixedly connected to the panel of sieve plate 3, arranged in a figure-eight pattern. A wing plate is fixedly connected to the lower side of the sieve plate panel 3, with the two ends of the two strips, which are furthest apart, close to the wing plate. When ballast passes through the figure-eight strips, the flow trajectory of the ballast changes due to the angle and position of the two strips, allowing it to pass through sieve plate 3 more evenly, increasing the material contact area during screening, and thus improving screening efficiency. The wing plate bends downwards, acting as a guide, directing ballast particles larger than the sieve aperture downwards onto the track.

[0038] Ballast with a particle size larger than the sieve aperture meets the requirements for track ballast laying. 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 prevent problems such as subsidence and uneven settlement.

[0039] like Figure 1 and Figure 2 As shown, the bottom of the base frame 13 is equipped with pairs of steel wheels 16 at both ends, and the pairs of steel wheels 16 are rotatably connected to the base frame 13 via a rotating shaft. The distance between the same pair of steel wheels 16 is the same as the distance between two parallel rails of a railway track. When the base frame 13 is placed on the rail, the steel wheels 16 can slide on the rail.

[0040] like Figure 5 and Figure 8 As shown, a rear plate 131 is provided on one side of the raised end of the lower belt conveyor 7. The rear plate 131 is fixed on the base frame 13. The upper surface of the rear plate 131 is lower than the raised end of the lower belt conveyor 7. A lifting component 8 for transferring waste ballast is provided on the rear plate 131. 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 on the rear plate 131. The rotating rod 82 is rotatably connected to the support column 81. The rotating rod 83 is rotatably connected to the support column 81. Connected to the free end of rotating rod 82, electric hoist 84 is mounted on rotating rod 83. By rotating rotating rod 82 and rotating rod 83, electric hoist 84 can be moved horizontally. A storage bag is placed on the rear plate 131. Ballast stone thrown from the high end of the lower belt conveyor 7 enters the storage bag. After the storage bag is full of ballast stone, the operator can use 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.

[0041] Using this utility model, such as Figure 1 and Figure 2As shown, after the traveling device 1 moves onto the railway track, the frame 11 is placed on the rail, so that the four rollers 111 are on the rail. The pushers 112 on the two sets of frames 11 are activated to lift the entire traveling device 1 off the sleepers. The track of the traveling device 1 is removed from the railway track, and the rollers 111 are driven to rotate by the driver. The traveling device 1 moves on the rail through the rollers 111 driven by the driver. The bridge and tunnel cleaning screen machine that runs directly on the rail can more flexibly cope with complex track layouts and working environments. It can turn, change rails and cross various track structures directly on the railway like a conventional railway vehicle. The operation is more flexible and reduces the space and path restrictions caused by track walking. The bridge and tunnel cleaning and screening mechanism can be lifted and placed on the rails by the mechanical boom installed on the traveling device 1. The upper belt conveyor 5 and the lower belt conveyor 7 are driven by a motor. Starting the vibrating motor 4 can make the screen plate 3 vibrate. The ballast stone cleaned by the ballast cleaning device is first transported to the transmission belt of the upper belt conveyor 5 and moves upward to the screen plate 3. It is then thrown out from the high end of the upper belt conveyor 5. The feed hopper 6 can accurately receive the ballast stone thrown out from the end of the upper belt conveyor 5. After the ballast stone falls into the feed hopper 6, it is collected and then falls into the feed hopper 6. The ballast falls onto the vibrating screen plate 3, which has screen holes of a specific diameter. Ballast particles larger than the screen hole diameter are guided downwards onto the track through the wing plates, 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.
