Description

Mould goes in and out kiln primary and secondary car and mould and goes in and out kiln circulation system

Technical Field

The application belongs to the technical field of workshop conveyors, and particularly relates to a mold kiln inlet and outlet primary and secondary vehicle and a mold kiln inlet and outlet circulation system.

Background

At present, the production of concrete structural members is realized in a pipelining manner, and the working procedures of cleaning a die, spraying a release agent, placing steel bars, pouring concrete and the like can be finished on a production line. In the process, the mould advances along the track of the production line, sequentially passes through different stations, and completes corresponding working procedures on the stations. After the concrete structural member is poured in the mould, the concrete structural member needs to be cured under the conditions of stable temperature and humidity, and at present, a steam curing mode is mostly adopted, and a plurality of vertically stacked moulds are transported into a curing kiln from a production line track for curing.

Steam curing of concrete structures generally involves the following process: and (3) conveying the concrete structural member and the mould to a designated station in a curing kiln, then introducing steam into the kiln for curing for a certain time, and leaving the cured concrete structural member from the kiln. In the curing process, the door of the curing kiln is temporarily closed, so that the inside of the curing kiln is in a closed state. It should be noted that, due to the long curing time, the curing station cannot occupy the production line track, i.e. cannot directly pass the production line track through the curing kiln and perform curing on the production line track, otherwise, the production line is too long. In addition, after curing, a step such as demolding is required, and these steps are also performed on a production line.

Obviously, to achieve this, the following operations need to be performed in order: and removing the concrete structural member and the mould from the production line, transporting the concrete structural member and the mould to a designated position in the curing kiln, removing the cured concrete structural member and the mould from the curing kiln, and moving the cured concrete structural member and the mould back to the production line. In the process, the kiln entering and exiting direction of the die is difficult to be consistent with the circulation direction of the production line, so that the following problems are caused: if the mold is completed in the kiln and out of the kiln by using the same transport vehicle, the transport vehicle must change the moving direction when leaving the production line and entering the curing kiln or leaving the curing kiln and returning to the production line. However, the existing transport vehicles are mostly rail-type, and have large turning radius, if a plurality of rows of curing stations are arranged in the curing kiln, the spacing between two adjacent rows of stations is too large, and the space in the curing kiln cannot be fully utilized. If two transport vehicles are adopted, one transport vehicle is arranged on a production line and the other transport vehicle is arranged on a maintenance kiln track, the two transport vehicles are connected with an additional hoisting system, and when a plurality of maintenance tracks are arranged in the maintenance kiln, a plurality of transport vehicles are required to be connected with each other, so that the equipment cost is increased.

Accordingly, there is a need to provide an improved solution to the above-mentioned deficiencies of the prior art.

(6) After the sub-car 100 finishes limiting, the lifting device 102 on the sub-car 100 works, and the 4 hydraulic cylinders 1022 descend simultaneously to support the die by the supporting structure of the curing station, and then the hydraulic cylinders 1022 continue to descend to enable the die frame 1021 to be separated from contact with the die, so that the kiln entering of the die is completed.

After the mold is completely put into the kiln, the sub-vehicle 100 returns to the guide rail 201 along the second rail 302 and is positioned by using the third positioning assembly, and when the sub-vehicle 100 moves to a predetermined position of the guide rail 201, the hydraulic positioning fork 409 is inserted into the first positioning groove 410 again, so that the sub-vehicle 100 is locked with the mother vehicle 200 again.

Example 2

The present embodiment provides a mold kiln entrance/exit circulation system, as shown in fig. 9, including a first track 301, a second track 302, and a third track 303, where the first track 301 and the third track 303 are disposed in parallel and have the same structure, that is, the third track 303 is provided with a power supply device, a first metal detector 402, and a clamping board 403 that are the same as the first track 301.

A plurality of second rails 302 are arranged between the first rail 301 and the third rail 303, the second rails 302 are perpendicular to the first rail 301, rail surfaces of the first rail 301 and the third rail 303 are located on the same horizontal plane, the first rail 301 and the third rail 303 are provided with a mold in-out kiln primary-secondary vehicle in embodiment 1, the mold in-out kiln primary-secondary vehicle on the first rail 301 is used for mold in kiln, and the mold in-out kiln primary-secondary vehicle on the third rail 303 is used for kiln outlet after mold maintenance is completed.

The working flow of the mold kiln inlet and outlet circulation system is as follows:

(1) The mold entering and exiting kiln master-slave vehicle on the first track 301 completes the mold entering kiln;

(2) After the concrete structural member in the mould is cured in the curing kiln, the mould on the third rail 303 enters and exits the kiln primary-secondary vehicle to convey the mould from the second rail 302 to the third rail 303, and the mould is discharged from the kiln.

After reaching the third rail 303, the mold on the third rail 303 is transported to a downstream production line, such as a demolding station, along the third rail 303 by a mold in-out kiln master-slave vehicle.

In summary, by adopting the mold kiln inlet and outlet circulation system, the limitation of the production line track on the kiln inlet and outlet circulation routes of the mold can be reduced to the greatest extent, the occupied area of the production line is saved, and the space in the curing kiln is fully utilized; the kiln entering and the kiln exiting of the mould are respectively carried out by adopting two sets of primary and secondary trucks, so that the first-in first-out and then-in last-out of the mould can be realized, and the kiln exiting route of the first-in kiln mould is prevented from being blocked by the later-in kiln mould.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
