Description

The invention relates to a lowering and lifting station of a hinge track operated automatically and manually. The lowering and lifting station is used to move the movable section of the taxiway in the vertical direction so that the transport trucks can be moved between the taxiways at different heights or in different heights. loading and unloading a load on a transport trolley outside the taxiway level.

Previously known designs of lowering and lifting stations are formed by supporting columns anchored to the floor (base), which are mutually connected at the upper part by traverse and at the same time fastened to the supporting grid of the taxiway.

The support pegs are provided with a guide from the outside, along which the station carriage is moved by means of guide rollers and by means of support means (ropes, chain), counterweight and drive. The trolley of the station consists of a complicated spatial frame, to which a movable section of the taxiway is fixed by means of brackets in the upper part.

By means of hinges, support means and a guide roller assembly, the station carriage is coupled to the drive and counterweight. The drive of the lowering and lifting station is located in the lower part of the station behind the supporting tines. The counterweight moves in the guide located behind or between the supporting pins.

As a rule, the movable section of the carriageway or the station carriage is equipped with a locking device to prevent the transport car from falling off the track. The locking device is pneumatically operated. The station is equipped with adjustable stops in the upper part and fixed stops in the lower part.

The disadvantage of this solution is that the lowering and lifting station has a large installation size and construction due to the construction of the carrier system, the carriage of the station, the large installation dimensions, the following construction solution requires high production accuracy which affects the technological demands of production and increased production and assembly costs. The need and use of multiple types of energy for operation and operation.

These drawbacks are overcome by the hitching line lowering and lifting station according to the present invention, which consists of a rigid frame made of support posts and a draft frame connected to the support grate, where the station carriage moves along guides mounted on the inner side of the support posts.

The station carriage consists of a simple spatial frame provided with longitudinal sides of the guide rollers, which guarantee it a perfect guidance in two perpendicular planes. The running profile rigidly connected in the middle to the station carriage represents a movable section of the running track.

The running profile can be without trolleys, with trolley or other equipment used for driving and driving transport trucks, according to the method of driving transport trucks. The fixed and movable section of the taxiway are equipped with locking levers to prevent entry and exit respectively. the transport cart falls off the taxiway at an incorrectly set station.

The movement of the locking levers is derived from the movement of the station carriage. The station carriage is connected to the counterweight by means of adjustable hinges and load chains, via a drive and guide chain pulley.

The counterweight moves in taut guides. The drive located in the upper part of the station drive frame consists of an electric motor, a clutch with a brake disc, a service brake, a gearbox, a drive and a guide chain pulley. The station is equipped with flexible adjustable stops in the upper part and fixed stops in the lower part. A fixed bumper is placed on the floor under the counterweight.

The new solution of the lowering and lifting station will achieve smaller installation dimensions of the equipment, easier production and assembly. By positioning and solving the safety device (blocking the transport trolley) the operation safety will be increased.

A schematic outline of one particular embodiment of the invention is shown in the accompanying drawings, in which: FIG. 1 is a front view of the lowering and lifting station; FIG. 2 shows a side view of the lowering and lifting station, FIG. 3 shows the locking levers from above and FIG. 4 locking levers - side view.

Lowering and lifting station / fig. 1 and FIG. 2) consists of support posts 4 anchored to the foundation by means of screws 2 ^{in the} upper part connected to each other by means of the drive frame and the support grid 50. The rigid frame thus formed ensures perfect guidance of the station carriage in two mutually perpendicular planes.

At the top of the station, an electric motor 6 is provided on the drive frame 2, provided with a flywheel 17, which is connected to the gearbox 60 by a flexible clutch 7. The service brake is a double jaw 8 driven by an electromagnet 2 of the drive chain pulley 14 mounted in the bearing housings 13 connected via a clutch 11 to the output of the gearbox. The guide chain pulley 16 rotates freely on a pin 15 which is fixed in the of the drive frame.

The simple space frame of the station carriage 4 is provided on its long sides with four pairs of front guide rollers and four lateral guide rollers, which are designed to allow the station carriage 5 to be guided perfectly in the guides 4 located on the inside of the support posts.

The running profile 20 connected in the middle with the station carriage 5 represents a movable section of the running track being provided at both ends with locking levers 22. Similarly, the fixed sections 52 of the running track are provided with similar locking levers 23. Locking levers 23 and 22 prevent entry and exit respectively. the transport carriage falls out of the stationary section 52 or from the running profile 20 of the movable section of the carriageway at an incorrectly adjusted station.

The top carriage 5 provided with a pair of adjustable hinges 24 is connected to the counterweight 26 of the segmental structure by means of chains 25 via the drive 14 and the guide pulley 16. The counterweight 26 moves in the tensioned guides 27, which are anchored in the drive frame 6 and the support posts 6.

The lowering and lifting station is provided in the upper part with flexible adjustable stops 27, which are fastened to the frame of the drive by means of the stop brackets 28, in the lower part there are fixed stops 28 on the inner side of the posts. , which in case of an accident catches the counterweight 26.

A folded flexible cable 30 serves to supply electrical power and control signals to the trolleys 21 located on the running profile 20.

The locking lever 22 / FIG. 3 and 4) is fixed to the running profile 20 by means of a bracket 31 and a pivot pin 32. The locking lever 22 is rigidly connected to the pin 32 and performs a rocking movement derived from the movement of the station carriage.

In the open position, the locking lever 22 holds the rod 35 which acts on the cam 33 fixedly connected to the pin 32. In the closed position the locking lever 22 holds the spring 34 / the closed position is shown in FIG. 4 in dotted lines.

The locking lever 23 / FIG. 3 and 4) is rigidly connected to the pin 38 and the angular lever 37. The cap 38 is rotatably mounted in the hinge 50 of the fixed section 52 of the travel track. The locking lever 23 performs a rocking movement derived from the pawl of the station carriage. In the open position it is held by the rod 36, in the closed position by shifting the weight of the angle lever 37.
