SU376233A1 - DEVICE TO STOP THE TRANSFER TROLLEY - Google Patents

Description

one

The proposed device can be used in the manufacture of building materials, such as bricks, for pushing and pushing trolleys with raw brick from the drying chamber.

A device for stopping a transfer cart is known, comprising a fixed stop mounted on the tracks and a slider with a tooth mounted on the frame of the cart.

However, such a device does not provide accurate stopping of the cart

The proposed device does not have this drawback and differs from the well-known fact that an endless shaped chain connected to a driving gear wheel is mounted on a trolley frame and is supported with reversible movement along mutually parallel guides movable sliders with hingedly mounted teeth.

FIG. 1 shows the described device in the working position; in fig. 2 - the same, but in the transport position; in fig. 3 - transfer carriage and sliding paths, view in plan; in fig. 4 - transfer cart with device, general view.

The exact stop device consists of an endless profile chain / mounted on two 2n 3 profiled gears. The gear wheel 3 through a gearbox 4 is connected to an electric drive 5. Two moving sliders 6 are mounted and fixed on the driving and driven branches of the profile chain movements along mutually parallel guides 7. The crawlers are osashchascheni sharniri-fixed teeth with mi-stops 8. The described units of the device with the help of console-dert Ael 9 are attached to the frame of the transmission teleski 10.

The fixed stop 11 is rigidly fixed to the track x 12, at the place where the exact stopping of the transfer carriage is required. The number of stops is determined by the number of required stopping points.

The exact stop device works as follows. The transfer cart 10 is guided to a predetermined location, and at this point the drive (not shown) of the main motion of the cart is turned off and the drive unit 5 of the device is turned on, which through the gearbox 4 drives the drive gear 3 and the profile chain which engages with it /. Simultaneously with the profile chain, the sliders 6 mounted on the chain 6 begin to move in opposite directions along the chains. When the sliders exit the extreme positions, the teeth of the stops 8 come off from the holder-console 9 and lower into the working position, ensuring reliable engagement with the fixed stop 11.

Moving along the guides, one of the sliders (left) will abut the tooth 8 into the fixed support and will start, pushing from the fixed support to move the cart 10 to the specified position. The process of moving the trolley away from the drive of the fine stop device will continue until the tooth-stops 8 of both sliders abut against the fixed stop 11. This completes the exact stop process.

Since the device can be stopped only after resting both teeth into a fixed stop, and the tooth stops are mounted on sliders that move evenly with the profile chain, the stop will always occur when the sliders are located at the same distance from the center of the device.

Subject invention

A device for stopping the transfer carriage comprising a fixed support mounted on the tracks and a slider with a tooth mounted on the carriage frame, characterized in that, in order to improve the carriage stopping accuracy at any given place, an endless chain connected to the drive gear wheel is mounted on the carriage frame, on which are mounted with the possibility of reversible movement along mutually parallel guides movable sliders with articulated teeth.
