Description

The invention relates to road construction and is intended for heating bitumen and pouring cracks and seams of the road surface, in particular asphalt concrete, and can be used both in construction and in road repair.

A device is known for heating bitumen material (ed. Certificate of the USSR 536276, class E 01 C 19/08, 1976), in which an open container for heated bitumen has L-shaped partitions installed under its outlet, and a flame tube equipped with an expanding pipe, which is mounted at its outlet. During operation, the molten bituminous material, flowing down onto the pallet, is subjected to additional intense heating by a pulsating gas stream, reaching operating temperature, and then flows down a gentle slope onto a road surface.

The disadvantage of this device is the design complexity, the fire hazard of the heating system of the device, the inconvenience of operation, low quality and insufficient casting efficiency.

The closest technical solution compared to the claimed one is a installation for pouring and repairing joints, including a frame with a boiler installed on it with heat pipes and a lever for opening the shutter for the release of bitumen, a gas bottle with a reducer, hoses for gas burners. A handle for transportation is installed in the back of the device and it is equipped with front non-rotary and rear swivel wheels with an adjustable brake mechanism (PCT Application WO 02/14610, A1 dated 02.21.2002, Е 01 С 23/14).

A disadvantage of the known device is the low quality of pouring cracks in the road surface due to the uneven supply of bitumen, which leads to an uneven, inhomogeneous seam.

The problem to which the invention is directed, is to increase the efficiency and quality of poured joints and cracks by ensuring a uniform distribution of bitumen and improving the adhesion of bitumen with road surface.

The essence of the invention lies in the fact that in a device for filling cracks and seams of asphalt concrete pavement containing a frame with a boiler installed on it with a lever for opening the bitumen discharge valve, a gas cylinder with a reducer and hoses connected to gas boiler heating burners, a handle and wheels for transportation of the device, an additional control lever with a slide in the form of a U-shaped frame with two travel stops at its ends is installed on the frame, the front of which is installed at an angle of 60 ° on the transverse a slide rail, which has a cutout in its lower part to give the seam an optimal shape, and a rear travel stop is mounted on one of the longitudinal walls of the slide, with expanders in the upper part. The slide is connected to the control lever by a semi-rotary articulated joint, consisting of two eyes mounted on the free ends of the slide and studs, rigidly fixed to the upper crossbar of the slide control lever, which is mounted on the frame with the possibility of its rotation around the attachment point. The control lever consists of a handle with two transverse bars on which the slots for installing the burner are located. In addition, in the oarlocks on the walls of the boiler there is a mixer with a removable handle.

The invention is illustrated by the drawing, where Fig. 1 is a general view of the device, Fig. 2 is a slide, a top view, Fig. 3 is a view along arrow A, Fig. 4 is a view along arrow B, Fig. 5 is a control lever, view side and top, Fig.6 is a boiler in section with a mixer.

The device is a frame 1, on which a boiler 2 with a lever for opening the shutter 3 is installed, a gas cylinder 4 with a reducer 5 and gas hoses 6, which are connected to gas burners - one boiler heating (not shown in the drawing); another burner 7, which has two positions - heating the slide and the processed crack (7.1, 7.2, respectively)). The slide 8 consists of: a U-shaped frame 9, a front travel stop 10 mounted on the transverse wall at an angle of 60 °, expanders 11 in the upper part of the longitudinal walls, a rear travel stop 12 and eyelets 13, which provide a semi-swivel articulation of the control lever 14 s sled by means of studs 15, nuts 16 and washers 17. The studs are welded to the transverse beam 18, which in turn is welded to the slide control lever. The frame is equipped with wheels - a rotary wheel 19 with an adjustable brake mechanism and two rigidly connected to the frame 20. In addition, in the oarlocks 21 on the walls of the boiler there is a mixer 22 with a removable handle 23.

The device operates as follows: a cylinder 4 with liquefied gas is installed in the holder, a reducer 5, gas hoses are connected to it 6. The boiler 2, mounted on the frame 1, is loaded with pieces of solid bituminous material of phase dimensions, which when the device starts up are heated by the heat transferred from the walls heated by a gas burner (not shown in the drawing). For uniform heating, a stirrer 22 is provided in the device, by means of which bitumen is mixed through the handle 23 during heating. Before starting to fill the slide 8, it is necessary to warm up to the operating temperature with a gas burner 7, which for this is rearranged to position 7.1. After heating the sled, the burner is moved to position 7.2 to heat the treated crack. Using the opening lever of the boiler shutter 3, hot bitumen is fed into the slide 8, which are lowered onto the road surface by lever 14, which has 2 positions (transport and pouring position). In the design of the slide, expanders 11 are provided to exclude bitumen spillage and stroke limiters - front 10 and rear 12 for proper placement of the slide on the road surface. Part-turn swivel consists of studs 15, which are welded to the transverse crossbeam 18, nuts 16 and washers 17, which makes it possible to use slides of various sizes. The unit is moved manually using the handle for transportation. The rotary wheel 19, combined with a handle for transportation, is equipped with an adjustable brake mechanism. At the rear of the unit are wheels 20 rigidly connected to the frame. For periodic cleaning of the boiler, it is necessary to remove the mixer 22 from it and remove the burnt mixture with a spatula.
