DD203303A1 - COUPLING AND LOCKING DEVICE FOR HOISTS WITH BUNKER CARTS - Google Patents

Abstract

The invention relates to a coupling and locking device for hoists with hopper or bunker cars. It is also applicable for a storm-proof locking of the bunker car at the Fahrbahnendbegrenzung. The task is to control the coupling or decoupling of the bunker from the cab of the hoist out. According to the invention, a coupling hook is actuated by means of a lifting element arranged on the hoisting gear, which hook engages in a coupling bolt of the bunker carriage in the coupled state. By means of a driving lever, a locking hook, which is mounted on the bunker carriage, is simultaneously influenced via a crank and a connecting element, whereby the bunker carriage is unlocked from the roadway limit. The invention is applicable where additional funnel or bunker cars are used to increase the handling capacity of a hoist when loading railway cars with Schuettguetern.

a) Title of the invention. '·

Eopplungs- and locking device for hoists with bunker cars

b) Field of application of the invention

The invention relates to a eopplungs- and locking device for hoists with funnel or "bunker cars, both vehicles running on a common railroad track." By coupling a hoist with a funnel or bunker wagon is an increase in the loading of railway wagons with bulk materials Handling capacity of the hoist achieved.

The Eopplungs- and locking device is also applicable for a storm-proof locking of the hopper or »bunker car at the Sahrbahnendbegrenzung, ie when the hoist works in solo mode.

c) Characteristic of the known technical solutions

Are known hydraulically, electrically or by the Eopplungssto3 triggerable hook couplings. For example, in the case of a push and pull device for rail vehicles with a buffer, the locking lever mounted on the buffer housing is pivoted upwards. The locking lever · is at the same time on one

Pivot axis which is fixed to the buffer end plate aufο With the pivot axis is a lever connected in the coupling jaw is mounted _o This is secured the same in the engaged Xupplungsklaue against independent pivoting up, (see DT-CB 2639 911)

In another known hook coupling for a towing vehicle additionality is connected a piston working machine to a -vorhandenes hydraulic system of the tractor which moves the lever for the Eupplungshaken in a Eupplungsstellung "(see DT (B 2 637 528) this. Means the u _e a. When used in landmine and rail vehicle construction, it is not possible to realize an inevitable locking of the vehicle to be secured in the decoupled state. "The solution practiced so far in hoist construction is based on a manual coupling or uncoupling of the hopper or bunker wagon with the hoist ., The manual locking of the currentless hopper or bunker wagon was done in case of storm by tightening rail clamps, These solutions are time consuming and labor intensive.

d) Object of the invention

The aim of the invention is equalized manual and human effort in the coupling of a hoist.mit a. Hopper or bunker wagon to avoid * Also with the shutdown of the funnel or ". Bunker wagens at the end of the roadway, no manual and personal effort is required * It should improve the safety and health and safety. The hopper or bunker wagon should get by without a power supply and without a special traction drive «

e) Presentation of the essence of the invention

The lufgabe is the wahlweisea operation of the hoist with or without funnel or bunker cars to control the coupling or _o decoupling of Trichterbswa bunker car from the cab of the hoist while unlocking or locking the funnel or «bunker car with the Fahrbahnendbegrenzung ·

Only one actuator is required on each rail side of the common track. According to the invention, an actuating element for rotating a coupling hook mounted on a horizontal shaft together with a driver lever is arranged on the hoist in a coupling and locking device. In the coupled state of the coupling hook engages in a catch bolt, which is attached to the bunker car. At the hoist a Äbstandsschalter is also attached to the side facing the bunker car, the contact with sufficient approximation of the hoist to the Trichterbzw. Bunker car is closed. According to a further feature of the invention, a switch is attached to the coupling hook, which indicates the decoupled or coupled state,

If the hoist moves over the coupling point K1 in view of the bunker agent locked at the end of the roadway limit, the switch is activated by the switch when a ruler is reached ». By the actuator, the coupling hook and the follower lever are turned about their common horizontal axis , Upon reaching the bunker, the buffers, which are on both sides in the rail direction of the

Bunker wagons are fastened, pressed together and, the distance switch the actuator off «Then the coupling hook falls into the Fangbolzen.am the end of the coupling rod of the bunker .. At the same time, the coupling lever attached to the driving lever · engages in a laterally disposed at the end of the coupling rod crank on a fastener is attached. The connecting element connects the crank on one side of the bunker wagon with the locking hook on the opposite side of the bunker wagon. By lowering the: Driving lever, the crank is in sight hoist center. rotated and released connected to the locking element locking hook. The coupled position Hoist bunker wagon indicates a switch attached to the coupling hook. * Disconnecting the hoist bunker wagon while locking the bunker wagon at the end of the lane is done by switching on the actuating element from the cab of the hoist, when the switch, squeezing the buffers the bunker wagon has signaled that the bunker wagon is at the dismantling and locking point »

f) embodiment

The invention will be explained below with reference to an exemplary embodiment, Ss show:

1: The coupling and locking device with indicated hoist including hopper or "bunker cars,

Fig. 2: Details according to view A Fig. 3: section B-B to Flg. 2

To couple the hoist 1, here indicated as a portal crane, with a bunker 2, a coupling hook 3 is used? The coupling hook 3 is mounted on a horizontal shaft 5 and is rotated by an actuating element 6 (engine pusher) by approximately 30 °. Actuating element 6, horizontal shaft 5 and coupling hooks 3 are mounted on the bunker carriage 2 facing side of the hoist 1. On the horizontal shaft 5 is located together with the coupling hook 3, a driving lever 7 · This driving lever 7 engages in a arranged at the end of the Koppeistange 8 bunker 2 crank 9 »The crank 9 is connected via a connecting element 10 (cable) with the locking hook 11 , During downward movement of the coupling hook 3 · d thus the Mitnehserhebels 7, the connecting element 10 is tensioned and raises the preilbockseitig arranged on the bunker carriage 2 locking hooks 11. Thus, the locking hook 11 is excavated from the bracket 13 located on the stop bracket 12 and thus the locking of the bunker carriage 2 with the buffer-12 solved. For pressure transmission serve at the end of Koppels taage S and the chassis of the bunker 2 arranged buffers
