Description

Edge paver for pouring asphalt concrete

technical field

The utility model belongs to the technical field of pouring asphalt concrete paving equipment, in particular to a special edge paver for pouring asphalt concrete.

Background technique

At present, cast asphalt concrete is mainly constructed on the surface of traffic arteries, bridge decks (especially steel decks), tunnels, airports and cold areas. The existing pouring asphalt concrete paving equipment mainly includes a screed device and a car body for advancing the screed device, but the existing screed devices are all located in front of the car body, and during the propelling process of the car body, the total Is the dead corner of paving where wheels and edges exist. The paving dead corners of these wheels and edge positions can only be paved by manual operation, the paving efficiency is low, and the manual operation does not have a screed device, so the paving effect is not good.

Utility model content

The technical problem to be solved by the utility model is to provide a special edge paver for pouring asphalt concrete with high working efficiency.

The technical scheme of the utility model is as follows: a special edge paver for pouring asphalt concrete, including a car body, a transverse main beam is installed at the front end of the car body, and a transverse connecting rod is installed at least one end of the main beam, A screed device is connected in front of the connecting rod, and the screed device is located outside the wheels on the corresponding side of the vehicle body.

The connecting rod is connected with the main beam through a lifting device, and the lifting device includes a "冂"-shaped bracket fixed to the main beam, a screw that vertically penetrates the top surface of the bracket, and a nut that is sleeved on the screw. In the mouth, the connecting rod is fixed with the nut, and when the screw rotates, the nut and the connecting rod move up and down.

Vertical baffles are connected to the left and right sides of the front end of the ironing device.

A stirring tank is also installed at the front end of the car body, and a discharge port is opened on the side of the stirring tank facing the ironing device. The discharge port is connected with a hopper, and the hopper is made of a "U"-shaped bent plate. One end of the feeding hopper is connected to the discharge port of the mixing tank, and the other end is lapped on the baffle plate at the front end of the ironing device close to the car body.

A connecting rod and a screed are installed at the left end of the main girder.

A connecting rod and a screed are installed at the right end of the main girder.

Connecting rods and ironing devices are installed at both left and right ends of the main girder.

With the above-mentioned structure, an ironing device is connected to the front end of the car body through the main beam and the connecting rod. Mechanical paving in dead corners such as wheels and edges not only significantly improves work efficiency, but also has a far higher paving effect than manual operation. And the connecting rod is connected with the main beam through the lifting device, so that the height of the connecting rod and the ironing device can be adjusted conveniently, and the use is more convenient. The front end of the screed device is equipped with baffles on the left and right sides, which can control the width of the pavement, avoid splashing of asphalt concrete, and further improve work efficiency. A mixing tank is installed on the car body, and the space between the outlet of the mixing tank and the baffle is connected through the hopper, so that the asphalt in the mixing tank can be directly transported to the position where paving needs to be carried out by using the hopper. Work more efficiently. The connecting rod and the ironing device can be arranged at the left and right ends of the car body according to actual conditions.

Beneficial effects: the utility model connects the screed device at the front end of the car body through the main beam and the connecting rod. Mechanical paving can be carried out in dead corners such as wheels and edges under the ground, which not only significantly improves work efficiency, but also has a far higher paving effect than manual operation.
