Description

 The invention relates to the field of machines for repair and maintenance of roads and, in particular, to machines for patching roads with asphalt or asphalt-concrete coating.

 A well-known machine for patching, consisting of a trailed chassis, on which is mounted technological equipment with an executive working body. The seamstress with the equipment works in conjunction with dump trucks, in which there is rubble continuously fed into the receiving hopper of the technological equipment [Prospect of the company "ROSCORA-200", USA, 1988].

 The disadvantage of this machine is that it consists of two parts - a non-self-propelled chassis with technological equipment and a dump truck, which is a complex unit.

 Another machine is also known, which also consists of a trailed chassis with technological equipment and with an executive working body and a dump truck equipped with a device for feeding crushed stone.

 This machine for the layout of technological equipment on a non-self-propelled chassis and the mechanism for supplying crushed stone from the dump truck to the receiving hopper is less complicated than the previous analogue and is closest in its technical essence and the achieved result to the proposed technical solution and therefore adopted as a prototype [Company prospectus " DURA PATCHER ", USA, 1998, US Pat. USA 4,630,929, 1986].

 The equipment involved in patching is a crushed stone container, crushed stone feeding mechanism, tanks for bitumen emulsion with hoses, a compressor, an air duct, a rubble conduit with a tip with nozzles, handles and control buttons, control valves, a cantilever beam with flexible couplings suspension brackets .

Disadvantages of devices:
the use of a dump truck for storage and supply of crushed stone with a special device and for towing a non-self-propelled chassis;
application for the operation of equipment of an autonomous energy source in the form of an internal combustion engine;
the use of a special non-self-propelled chassis with suspension trolleys, complex in design and idle for a significant part of the year, as patching is carried out in dry weather at a temperature of at least 5 ^o C.

 Thus, the disadvantages are the complexity of the entire set of equipment, as well as the increase in the cost of the work process in connection with the additional constant use in the work of a specially equipped dump truck.

 The closest analogue is the equipment for patching the pavement, containing a container for crushed stone, a crushed stone supply mechanism, a tank for bitumen emulsion with hoses, a compressor, an air duct, a crushed stone pipeline with a tip with nozzles, handles and control buttons, control valves, a cantilever beam with flexible connections suspension of rubble wire (US Pat. US 5263790, 11/23/1993).

 The problem solved in the invention is to reduce the complexity of the equipment and reduce the cost of the work process.

 The solution to this problem was obtained by creating replaceable equipment for patching, used on the basis of a road machine that does not work in the warm spring, summer and autumn (spreader of technological materials PR-1) [Construction, road and special equipment. Quick Reference, 1996, p. 183].

 This problem is solved by the fact that replaceable equipment for patching the pavement, containing a container for crushed stone, a crushed stone feeding mechanism, emulsion tanks with hoses, a compressor, an air duct, a crushed stone wire with a tip with nozzles, a handle and control buttons, control valves, a cantilever beam with flexible links for the suspension of crushed stone, mounted on the base machine, which is used as a road car - a spreader of technological materials with dismantled blade and sand spreader, a compressor it is new on the bumper and has a drive from the power take-off; instead of a sandblaster, a feeder having a gate is installed on the output end of the hopper, connected on one side via an air duct to a compressor, and on the other hand with a rubble conduit, and a sand hopper of the base machine is used as a capacity for crushed stone , and for feeding crushed stone into the feeder - the conveyor belt of the base machine at the base of the hopper, and tanks for bitumen emulsion, connected by hoses to the brake system receiver of the base machine, are installed on both sides of the bun EPA through lodgements mounted on the machine frame base, wherein the cantilever beam with flexible connections schebneprovoda suspension by bracket attached to the rear end of the hopper, and the tanks for the bitumen emulsion feed hoses have band heaters mounted on the surface thereof.

 In FIG. 1 shows a general view of interchangeable equipment mounted on a base machine; FIG. 2 is a view along arrow A in FIG. 1; in FIG. 3 is a view along arrow B in FIG. 1; in Fig.4 - node In Fig. 1; in Fig.5 is a view of G in Fig. 1.

 Replacement equipment for patching is mounted on the base machine 1. A compressor 2 with a drive 3 from the power take-off 4 is installed by means of an arm 5 on the bumper 6 of the base machine 1.

 The compressor 2 is connected by an air duct 7 to a feeder 8 having a controllable gate 9, on the other hand, the feeder is connected to a rubble conduit 10. The feeder 8 is mounted on the output end of the hopper 11, instead of the dismantled sand distributor. The hopper 11 of the base machine 1 serves as a container for crushed stone. For feeding crushed stone into the feeder, a belt conveyor 12 of the base machine 1 is used in the base of the hopper.

 Tanks for bitumen emulsion 13, connected by hoses 14 to the receiver 15 of the brake system of the base machine, are installed on both sides of the hopper on the lodges 16, mounted on the frame of the base machine. The cantilever beam 17 with rigid bonds 18 of the suspension of the crushed stone wire 10 is attached to the rear end of the hopper 11 through the bracket 19. The tanks for bitumen emulsion 13 with supply hoses 14 have belt heaters 20 mounted on their surface under an insulation layer. The crushed stone wire 10 ends with a tip 21 having bitumen nozzles 22, the bitumen supply hose 23 is equipped with a crane 24, the arms 25 and 26 with electric buttons 27 for controlling the drive of the gate 9 and the conveyor 12 are mounted on the end of the crushed stone pipe.

 Works replacement equipment for patching, mounted on a base machine, as follows.

 Turn on the compressor 2, through the air duct 7 and the crushed stone wire 10 to the tip 21 begins to receive compressed air. Using the handles 25 and 26, the operator directs the tip 21 to the repaired pit of the pavement, due to this the working area is cleaned of unbound fragments of the pavement - dust, sand, gravel, etc. and dried.

 Then the operator opens the crane 24 and provides access to the working area of the bitumen emulsion, which is forced out of the tanks 13 by compressed air supplied through hoses 14 from the receiver 15 of the base machine 1. After treating the surface of the pit with bitumen emulsion, the operator switches on the buttons 27 of the conveyor 12 and the gate 9, as a result, crushed stone enters the feeder 8, which is entrained by the air flow through the crushed stone wire 10. When passing through the zone of nozzles 22 in the tip 21, the crushed stone is irrigated with bitumen emulsion and fed to the working area. After filling the pit with crushed stone with emulsion, the operator shuts off the emulsion supply with a crane 24, turns off the conveyor drive 12 and switches to closing the gate 9 of the feeder 8.

 To maintain the required temperature for heating the bitumen emulsion in the tanks 13, electric heaters 20 are connected to the 220 V network when the car is parked in between trips. For the operating mode, the heaters 20 of the bitumen hoses 23 are connected to the power supply of the base machine.

 As a result, the proposed invention has the following advantages.

 1. The use of a dump truck equipped with a crushed stone feed mechanism is excluded from the set of equipment.

 2. As the base machine, a machine that is not used in the warm season (spring-summer-autumn period) is used, in which, for the needs of patching, the hopper and conveyor available on the base machine serve as a crushed stone container and a mechanism feeding crushed stone to the feeder at the base of the hopper.

 3. It excludes the creation of a special non-self-propelled chassis with suspension trolleys, additionally equipped, in addition to the technological equipment used in the applicant’s proposal, with an internal combustion engine.

 4. The base machine, which is idle in the warm season, gets the opportunity to work all year round, which increases its utilization rate. In winter, removable patching equipment is removed from the base machine and a dump with a sand spreader is hung.

 In General, the proposed invention can significantly reduce the complexity of the machine for patching, equipped with the specified replaceable equipment, to exclude the use of expensive units and, therefore, to reduce the cost of patching.
