Abstract

 A mobile paver containing a vehicle equipped with a frame, a mixing and molding system with a set of sliding vibroforms hung on the frame, a conveyor, characterized in that a serial self-propelled machine is used as a vehicle, on which a mixing unit mounted on the portal and equipped with a skip hoist is mounted , a conveyor is installed along the frame, and a vibratory hopper is installed at the end of the frame, while the frame is rotatable relative to the axis of the mixing unit with the possibility of the location of the conveyor across and along the axis of movement of the machine and with the possibility of installing on it a vibration nozzle for laying the roadway.

Description

The utility model relates to road construction, in particular to devices for laying concrete pavement, concrete curbs, trays, sidewalks, etc.

The known technology of laying concrete pavement with the installation of elements of precast concrete curbs (Afanasyev A.A. Concrete work. - M .: Vyssh. Shk., 1991. P.159, 204).

A disadvantage of the known solution is the high operating costs associated with the manual implementation of concrete laying with vibratory rails, laying of curb elements and with the delivery of concrete by dump trucks.

The closest in function and achieved result is a mobile device for continuous laying of concrete curbs, trays, sidewalks, etc., adopted as a prototype, containing a hopper, conveyor, a set of sliding vibroforms of various profiles (Margaylik E.G. Pavers of foreign firms / / Construction and road machines - 1992, No. 6. P.16, prototype).

The disadvantages of the prototype are limited functionality, low quality molded structures and limited scope, indicating the low efficiency of the prototype due to the fact that a specially designed tractor is used, which has a constant system for receiving and laying concrete mix, there is no own mixing equipment, the device runs on imported concrete, no means for laying the roadway.

The objective of the utility model is to reduce the cost of the unit through the use of serial self-propelled machines, on which removable mixing and molding equipment is hung; ensuring the autonomy of the device and the exclusion of dependence on the presence of a concrete plant; improving the quality of concrete by refusing to transport it; expanding the scope of the mobile paver by introducing the paving function.

To solve this problem, in a mobile paver containing a vehicle equipped with a frame, a mixing and molding system with a set of sliding vibroforms hung on the frame, the conveyor, according to a utility model, uses a self-propelled serial machine as a vehicle on which the mixing unit mounted on portal and equipped with a skip hoist, a conveyor is installed along the frame, and a vibro-hopper is installed at the end of the frame, while the frame is rotatable relative to the axis of the mixing unit with the possibility of arranging the conveyor across and along the axis of movement of the machine and with the possibility of installing on it a vibration nozzle for laying the roadway.

Figure 1 schematically shows a mobile paver, top view; figure 2 is a view with a nozzle for forming pipes; figure 3 - nozzle for forming a border; figure 4 - nozzle for forming trays; figure 5 is a fragment of a General view.

The mobile paver contains a serial self-propelled vehicle 1 with a process hydraulic system, for example, a TT-4M forest skidder. A concrete mixer 2 installed on the portal, equipped with a skip hoist 3, and a swing frame 4, on which a conveyor 5 is mounted, is mounted on the tractor. A vibro-hopper 6 is mounted at the end of the swing frame 4, sliding vibroforms 7 of various configurations can be installed under it, and can also be elastic fixed vibration nozzle 8 for laying the roadway.

Mobile paver operates as follows.

In the bucket of the skip hoist 3 from the car, a metered amount of aggregate and cement are loaded, which are lifted into the concrete mixer 2, where water flows from the batcher. After mixing in the concrete mixer 2, the rigid concrete mixture is fed to the conveyor 5 and then to the vibratory hopper 6. A sliding hydraulic vibrator 7 is turned on and the vehicle 1 with a speed reducer starts continuous movement along a predetermined path, leaving a molded concrete structure 9 covered with a film or tarpaulin for strength gain concrete in vivo. During operation, the mobile paver operates at two positions of the rotary frame 4 with a conveyor mounted on it 5. For forming the curb, trays, sidewalks using sliding forms 7, the rotary frame with the conveyor is located across the axis of movement of the vehicle, and for concreting the roadway using a vibrating nozzle 8 - along the axis of movement of the vehicle.

Thus, in comparison with the prototype, the proposed mobile paver has a mixing and molding unit temporarily hung on a serial self-propelled vehicle, which reduces the cost of the mobile paver, allowing the vehicle to be used for another purpose after the completion of concrete work, while increasing the autonomy of the unit due to failure from imported concrete, as well as expanding the scope by adding the function of concreting the roadway.
