In the following specific embodiment of the distributing device for pouring the high-speed railway sealing layer, the advancing direction of the distributing device for pouring the high-speed railway sealing layer is taken as the front, and the direction perpendicular to the advancing direction of the distributing device for pouring the high-speed railway sealing layer is taken as the left-right direction.
A material distribution device for casting a high-speed rail sealing layer, as shown in fig. 1, comprises: the device comprises a vehicle body 1, a material distribution mechanism 2 arranged on the vehicle body 1 and a power mechanism 3 used for driving the vehicle body 1 to move.
The body 1 is used for carrying the material distribution mechanism 2, so that the material distribution mechanism 2 can move forward and distribute the material under the driving of the body 1. In order to better realize the bearing function of the vehicle body 1, the upper surface of the vehicle body 1 can be of a plane structure. The vehicle body 1 includes wheels 101 and other necessary components capable of moving the vehicle body 1; the structures of other necessary parts of the vehicle body 1, and the positions and connection relationships between the wheels 101 and other necessary parts of the vehicle body 1 can be implemented by using the prior art, and are not described in detail herein.
The vehicle body 1 needs to meet the running condition of the ballastless track bed capable of crossing the left side and the right side of the high-speed rail sealing layer. In order to ensure that the finished products of the auxiliary projects on the ballastless track bed cannot be damaged in the running process of the vehicle body 1 across the ballastless track bed on the left side and the right side of the high-speed rail enclosed layer, the wheels 101 on the left side and the right side of the vehicle body 1 are required to be positioned at the central position or near the central position of the ballastless track bed. Specifically, the distance between the wheels 101 positioned on the left side and the right side of the vehicle body 1 is a first distance, the distance between the centers of the ballastless track beds on the left side and the right side of the high-speed rail sealing layer to be poured is a second distance, and the first distance is 0.8-1.2 times of the second distance.
The wheels 101 of the vehicle body 1 are made of rubber tires so as to prevent the wheels 101 from scratching auxiliary engineering finished products on a ballastless track bed. The wheels 101 may include front and rear wheels; the front wheels are arranged at the front end of the vehicle body 1, and the rear wheels are arranged at the rear end of the vehicle body 1. Specifically, as shown in fig. 1, the rear wheels may be double-row wheels.
The distributing mechanism 2 is used for pouring concrete materials at the position where a high-speed rail sealing layer needs to be formed. The distribution mechanism 2 may include a storage unit 201, a material sliding unit, and a leveling unit 203.
The storage unit 201 is arranged on the vehicle body 1 and has a discharge port. The discharge hole of the storage unit 201 is located on the side of the storage unit 201 and faces the front. The storage unit 201 functions to temporarily store concrete materials. The shape and the size of the composite material can be determined according to specific construction requirements. Specifically, as shown in fig. 1, a cylindrical structure may be adopted. The storage unit 201 and the vehicle body 1 can be in a connection relationship or a contact relationship; for example, the magazine unit 201 may be placed directly on the vehicle body 1.
The discharge hole of the storage unit 201 is used for discharging the material in the storage unit 201. In order to facilitate thorough material discharge, fast material discharge speed and energy saving, the discharge hole may be located at the bottom of the material storage unit 201. At this moment, the material can be discharged from the discharge port by virtue of the gravity of the material, and the material located at the bottom of the storage unit 201 can also be discharged from the discharge port.
To further enable the material to be completely discharged from the magazine unit 201, the inner bottom surface of the magazine unit 201 may be provided as a slope, the lowest position of which is located at the discharge port. In this way, the material in the storage unit 201 can flow from a high position to a lowest position (discharge port) under the action of the self gravity.
The material downslide unit has a first end and a second end. The first end of the material gliding unit is located below the discharge port and receives materials discharged from the discharge port, and the second end of the material gliding unit is lower than the first end and protrudes forwards from the front edge of the vehicle body 1. There is certain difference in height between the discharge gate of storage unit 201 and the concrete position of placing of material, if the material directly falls to the construction position after coming out from the discharge gate, can produce the material and splash to cause the pollution to the accessory engineering finished product on the ballastless track bed. After the material gliding unit is arranged, the material discharged from the discharge port slides downwards along the material gliding unit, when the material gliding unit slides to the second end of the material gliding unit, the potential energy of the material gliding unit is obviously reduced, the height difference between the potential energy and the construction position is reduced, the construction position is fallen again, and the situation that the material splashes can not be generated.
The material gliding unit has the function of guiding the movement of the material. The material sliding unit can adopt a shallow groove structure similar to a slide structure as shown in figure 1; the materials slide down from the material sliding unit arranged on the slide.
Specifically, the second end of the material sliding unit may be higher than the bottom of the wheel 101. Under the condition that the position of the second end (lower end) of the material sliding unit is determined, the higher the position of the discharge hole is, the higher the position of the first end of the material sliding unit can be, and the faster the moving speed of the material can be. In order to increase the sliding speed of the material along the material sliding unit to a certain extent, a base 205 may be additionally arranged between the storage unit 201 and the vehicle body 1 to increase the possible height of the discharging port. Specifically, as shown in fig. 2, several support columns may be used as the base 205; for example, four evenly distributed support posts are used as the base 205.
And the leveling unit 203 is positioned behind the second end of the material sliding unit and is connected with the car body 1. After the materials are poured to the designated position, the leveling unit 203 performs leveling. The leveling unit 203 may employ an existing concrete leveling structure. Specifically, a spatula may be used. The scraping ruler can be horizontally arranged and arranged left and right as shown in figure 1.
The leveling unit 203 can be located at any position behind the second end of the material sliding unit. In order to perform timely leveling treatment on the materials, the leveling unit 203 may be disposed in front of the vehicle body 1.
In order to adapt to different leveling heights, the connection of the leveling unit 203 to the car body 1 can be designed in such a way that the height of the leveling unit 203 is adjustable. Specifically, the leveling unit 203 has a first connection position and a second connection position, the first connection position is hinged to the vehicle body 1, and the second connection position is statically connected to the vehicle body 1 through a length-adjustable connection member 206. The first connection position of the leveling unit 203 is hinged to the vehicle body 1, so that the leveling unit 203 can move up and down in the vertical direction. For example, as shown in fig. 3, a bracket 204 may be mounted below the front portion of the vehicle body 1, the bracket being attached to the vehicle body 1. The left and right ends of the leveling unit 203 are used as first connection positions to be statically connected with the bracket, and can be fixedly connected. The middle of the leveling unit 203 is hinged to the carriage as a second connection point via a connection 206. A rope can be used as the connecting member 206, one end of the rope is fixedly connected with the middle part of the leveling unit 203, and the other end of the rope is tied on the bracket.
