Scaffold bottom for transporting an aerated concrete block

The subject of the invention is a grate bottom for transporting a cut block of aerated concrete to a production station in a technological cycle.

The known and used grate bottoms do not have mechanisms for connecting and disconnecting the grate bottoms, while the connecting mechanisms are provided by carts for transporting concrete blocks. In the known grate bottoms, the plane of the transverse beams coincides with the upper edge of the longitudinal beams, forming at one level a common plane on which the concrete block rests.

The aim of the invention is to provide a grate bottom equipped with simple and reliable mechanisms for automatic connection and disconnection of the grate bottoms. The second goal is to develop a structure that allows better use of the autoclave capacity during the autoclaving process of aerated concrete blocks piled up on carts.

The grate bottom for transporting the aerated concrete block according to the invention is equipped with lock mechanisms for connecting and disconnecting the grate bottoms, and the two longitudinal beams are connected with cross beams spaced at equal distances to each other along the entire length of the bottom, and these beams are attached to the longitudinal beams below upper edge of the longitudinal beams. On the outer side of the longitudinal beams, two movable catches are fastened in pairs at one end, and fixed hooks are mounted on the opposite end. The catches are located on the lever combined with the sleeve mounted on the shaft, the angular position of which depends on the position of the control lever. The control lever works with cams located along the transport route.

The structure of the slatted bottom with a lowered grate pallet in relation to the longitudinal supporting beams enables optimal use of the working space in the autoclave by arranging a block of autoclaved concrete in an area allowing for a block with a greater transverse dimension.

The subject of the invention is illustrated, for example, in the drawing, in which fig. 1 shows the grate bottom in an axonometric view, fig. 2 - self-locking mechanism in the blocking position of the bottom, fig. 3 - self-locking mechanism in the open position after

The grate bottom consists of two longitudinal steel beams 2 connected by crossbeams 3 spaced at equal distances from each other along the entire length of the bottom. On the longitudinal beams 2, at one end there are catches 5, and at the opposite end there are hooks 8. The tacking or uncoupling takes place automatically under the influence of the control lever 7 mounted on the shaft 6. Deflection of the planer lever 7 causes the shaft to rotate through a certain angle, which at the same time causes the deflection of the lever on which the catch 5 is mounted. In the working position, the catch 5 catches the hook 8, which causes the joining of two grate bottoms. Unlocking also takes place as a result of changing the position of the control lever 7, which, by turning the shaft 6, disengages the catch 5 from the hook 8. The location of the crossbeams 3 below the upper edge of the longitudinal beams 2 allows for better filling of the working volume of the autoclave, as it lowers the height of accumulation on the autoclave cart, enabling the autoclave to be loaded. concrete block 1 of greater width.

Grate bottoms for the transport of an aerated concrete block according to the invention allow to improve the operation of the technological line and improve the quality of manufactured products made of aerated concrete.

Claims (2)

Patent claims 1. Scaffold bottom for transporting an aerated concrete block to production stations, characterized by the fact that it is equipped with lock mechanisms (5), 7,8) for connecting and disconnecting the grate bottoms, and cross beams (3) are suspended on the longitudinal beams (2) below the upper edge of the longitudinal beams (2) to form a pallet on which the concrete block rests between the longitudinal beams. 2. The grate bottom according to claim 3. The method of claim 1, characterized in that the lock mechanism consists of a movable catch (5) located on the lever integrated with the sleeve mounted on the shaft (6), the angular position of which depends on the position of the control lever (7) mounted on the same shaft (6) and a fixed hook (8) cooperating with the catch of the adjacent grate bottom is fixed to the longitudinal beam at the opposite end of the bottom.
