Description

Technical Field

[0001] This utility model relates to the field of dredging equipment technology, and more specifically, to a railway culvert cleaning and dredging device. Background Technology

[0002] Railway culverts are water passages built below the road surface during railway construction to drain floodwaters across natural valleys and depressions or to serve as irrigation canals for farmland. Their primary function is to quickly remove surface water along the railway line, ensuring the safety of the roadbed. Over long-term use, excavated soil, slag, silt, and other debris can easily accumulate and clog railway culverts due to rainwater impact and wind erosion. This creates a safety hazard as blocked water flows rise and erode the railway roadbed. If the roadbed collapses, it can easily lead to serious railway traffic accidents. Currently, there are no automated dredging and clearing devices for small railway culverts on the market; cleaning is primarily done manually with shovels, which is extremely inefficient, costly, and involves harsh working conditions.

[0003] Utility model CN211596884U discloses a dredging and clearing device for water conservancy projects, including a chassis. A housing is located at the front end of the chassis, and a conical surface is provided on the front side of the housing. A central motor and a secondary motor are located inside the housing. The output end of the central motor is connected to the shaft of a horizontal conveying auger. The rear end of the horizontal conveying auger is connected to an inclined conveying auger, and the upper end of the inclined conveying auger is connected to a sludge storage tank. The horizontal conveying auger is fixed to the chassis by a fixing plate, and a rotating rod is connected to the output shaft of the motor. When the horizontal conveying auger is overloaded, the entire machine body is prone to radial rotation, preventing the conveying auger from transporting the sludge. Furthermore, this device cannot be modified or lengthened according to the depth of the culvert, resulting in low flexibility. Utility Model Content

[0004] To address the problems of the prior art, this utility model provides a railway culvert cleaning and dredging device.

[0005] The technical solution adopted in this utility model is:

[0006] A railway culvert cleaning and dredging device includes a tunneling section and a splicing section fixedly connected to the tunneling section. The tunneling section includes a tunneling mechanism and a conveying mechanism. The tunneling mechanism includes a tunneling motor fixedly installed on a fixed frame. The tunneling motor is connected to a rotating shaft and then to a digging paddle, which is located at the front end of the tunneling section. The conveying mechanism includes a conveyor motor and a first conveyor belt. One end of the first conveyor belt is connected to a first conveyor belt hanger, which is slidably connected to the fixed frame. The other end of the first conveyor belt is connected to a second conveyor belt hanger, which is slidably connected to the rotating shaft. The splicing section includes a second conveyor belt suspended on the fixed frame. One end of the second conveyor belt is connected to the first conveyor belt hanger, and the other end is connected to the second conveyor belt hanger. The first and second conveyor belt hangers are slidably connected to the fixed frame, and transmission rotating shafts are provided at both ends of the second conveyor belt.

[0007] Furthermore, the fixing frame includes multiple circular frames, which are fixedly connected as a whole by connecting rods. A retainer is fixedly installed on the connecting rod, and the retainer is "Y" shaped with its three ends fixedly connected to the steel pipe.

[0008] Furthermore, a conical hopper is provided at the front end of the tunneling section.

[0009] Furthermore, the circular frame is equipped with wheels on the side that contacts the culvert.

[0010] Furthermore, the first conveyor belt hanger and the second conveyor belt hanger are slidably connected to the retainer via a movable shaft.

[0011] Furthermore, a gearbox is also provided between the tunneling motor and the rotating shaft.

[0012] Furthermore, the conveying motor is vertically mounted on the cage and connected to the commutator, which is equipped with a drive sprocket.

[0013] Furthermore, the conveyor belt is provided with a drive shaft, and a gear set is provided on the drive shaft. The gear set is connected to the drive sprocket of the commutator through a drive chain.

[0014] Furthermore, the two ends of the conveyor belt are provided with drive shafts, and driven gears are provided on the drive shafts. The driven gears at the beginning and end of the adjacent spliced ​​sections of the conveyor belt are connected by driven chains.

[0015] Furthermore, the conveyor belts between the spliced ​​sections have a height difference of 10-30 cm at the joint. Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention solves the problem of silt not being transported smoothly during the device's forward or tunneling process by setting the connection between the conveyor belt and the fixed frame as a sliding connection, using gravity to keep the conveyor belt in a drooping posture. This is because the conveyor belt rotates radially due to load imbalance. The tunneling section of this invention can be lengthened by adding splicing sections, which can adapt to dredging operations in culverts of different depths, greatly improving flexibility.

A conical hopper 5 is provided at the front end of the tunneling section. The conical hopper 5 can collect and gather the silt dispersed by the excavating paddle 6 and then drop it onto the conveyor belt 12. A gearbox is also provided between the tunneling motor 11 and the rotating shaft 9 to adjust the speed of the excavating paddle 6 to adapt to different working conditions.

[0029] The conveyor belt hanger 12 and the conveyor belt hanger 20 are slidably connected to the cage via a movable shaft, so that the conveyor belt is always in a drooping state under the action of gravity.

[0030] The conveyor motor 13 is vertically mounted on the retainer 8 and connected to the commutator. The commutator has a drive sprocket 14. The first conveyor belt 12 has a drive shaft with a gear set 17.

The second conveyor belt 20 has drive shafts at both ends with driven gears 19. The driven gears 19 are connected to the gear set 17 via driven sprockets 18 to obtain power transmission. The driven gears 17 at both ends of adjacent spliced ​​sections of the second conveyor belt 20 are also connected via driven chains 18 to form the entire conveyor belt conveying operation.

[0031] During operation, the excavation section 1 is advanced into the culvert that needs dredging. Then, a quick-connect splicing section is made at the tail of the excavation section 1. The number of splicing sections is increased according to the depth of the culvert operation. During the advance of the device, the excavation motor 11 drives the digging paddle 6 to rotate continuously. The paddle blades continuously cut the silt, sand, debris, etc. and scoop them into the bucket by the conical hopper 5. They then fall onto the first conveyor belt 12. The first conveyor belt 12 then transports the silt to the second conveyor belt 20 of the splicing section 2, and finally delivers the silt to the entrance of the tunnel.

The number of splicing sections is increased according to the depth of the culvert operation.
