Description

A platform under the rear car

technical field

The utility model belongs to the field of arm-type stackers, in particular to a platform for lowering a trailer.

Background technique

The arm stacker is a general-purpose large-scale continuous bulk material conveying equipment, which is mainly used in the storage yards, warehouses, power stations, and coal power plants in the fields of metallurgy, electric power and chemical industry. The platform under the tail car is mainly used for placing the electrical room, cable reel, water tank, etc. of the arm stacker.

The existing lower platform of the tail car is mainly composed of four main beams and several primary beams, and the number of main beams is large and the manufacturing cost is high. The electrical room is arranged near the front outrigger on the lower platform of the rear car, and is located on the upper and lower symmetrical centerlines of the front and rear outriggers. The upper part is the tail car belt conveyor. The material leaked by the belt conveyor affects the electrical roof and is not easy to clean. The four main beams are connected with the high-strength bolts of the front and rear outriggers. Due to the large number of bolts, the error is large, and the installation and adjustment are inconvenient. When the width is greater than five meters, it is necessary to dismantle all the first beams in the middle of the lower platform of the tail car, so as to make two parts that are convenient for transportation.

Contents of the invention

In order to solve the above-mentioned technical problems, the utility model provides a low-cost trailer platform that can prevent material from accumulating on the electrical roof.

The technical solution adopted by the utility model is: including two main beams, multiple first beams, electrical room support beams and second beams, the two main beams are arranged in parallel, and the two main beams are connected with multiple first beams. The primary beams are connected to form a square frame; the two ends of the primary beams are respectively connected to the two main beams; Primary beam connection; the two ends of the main beam are respectively connected with the front outriggers of the tail car and the rear outriggers of the tail car, and the support beams of the electrical room are installed on the two main beams and the second beam, close to the tail The front outriggers are set to deviate from the rear car belt conveyor.

In the above platform under the tail car, the support beam of the electrical room is installed on the upper main beam of the lower platform of the tail car.

In the above platform under the tail car, the support beam of the electrical room is installed on the lower main beam of the lower platform of the tail car.

The above-mentioned tail car lower platform includes two electrical room support beams, one electrical room support beam is installed on the upper side main beam of the tail car lower platform, and the other electrical room support beam is installed on the lower side main beam of the tail car lower platform superior.

Compared with the prior art, the beneficial effects of the utility model are:

1. The bracket beam of the electrical room of the utility model is installed outside the material leakage range of the tail car belt conveyor, which effectively prevents material accumulation on the electrical roof;

2. The number of main girders of the utility model is small, which reduces production costs and reduces high-strength bolt connection joints;

3. The utility model adds an electric room support beam to replace the main beam, which avoids the defect that the utility model needs to be dismantled from it for the convenience of transportation, effectively reduces the disassembly joints of the first beam, and optimizes the installation process;

4. Compared with the existing platform under the tail car, the utility model is light in weight and controls the material cost.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 2 and Figure 3, the utility model includes two main beams 1, multiple primary beams 2, electrical room support beams 3 and multiple secondary beams 4, and the two main beams 1 are parallel setting, two main beams 1 and multiple first beams 2 are connected to form a square frame; the first beams 2 are set perpendicular to the main beams 1, and the two ends of the first beams 2 are respectively connected with two main beams 1; The second beam 4 described above is set parallel to the main beam 1 and is located between the two main beams 1, and the second beam 4 is connected to the first beam 1; the two ends of the main beam 1 are connected by high-strength bolts The joint 11 is respectively connected with the front outrigger 5 of the tail car and the rear outrigger 6 of the tail car, and the support beam 3 of the electrical room is installed on the two main beams 1 and the second beam 4, and is set close to the front outrigger 5 of the tail car , deviate from the tail car belt conveyor, so that the electrical room support beam 3 of the present utility model is installed outside the material leakage range of the tail car belt conveyor, effectively preventing material from accumulating on the electrical roof.

The support beam 3 of the electrical room can be installed on the upper main beam of the lower platform of the tail car, or can be installed on the lower main beam of the lower platform of the tail car. When two electrical rooms need to be set, two electrical room support beams 3 can also be provided, one electrical room support beam 3 is installed on the upper main beam of the lower platform of the tail car, and the other electrical room support beam 3 is installed on the rear car On the lower main girder of the lower platform. The utility model increases the support beam 3 of the electrical room, which avoids the defect that the utility model needs to be disassembled for the convenience of transportation, effectively reduces the dismantling joints of the first beam, and optimizes the installation process.

The structure of the utility model includes two main girders, the number of which is less than that of the existing platform under the tail car, which reduces the production cost of the utility model, and reduces the number of main beams 1 and the front legs 5 of the tail car and the rear of the tail car. The high-strength bolted joints 11 to which the legs 6 are connected. Moreover, compared with the existing platform under the tail car, the utility model is light in weight and controls the material cost.
