Description

(5) CAPABLE DEVICE FOR CONTAINERS

-. , I. . ; . ,

  The invention relates to lifting devices.

A load gripping device is known, comprising a supporting frame, drive gripping bodies mounted on it, and an eyelet for hooking a crane to the hook

However, this device does not provide the possibility of overloading and filling containers with cargo.

The closest to the invention to the technical essence is a container gripping device comprising a supporting frame, mounted gripping bodies thereto and a drive for raising and lowering the frame, including a lifting mechanism connected to the supporting frame by means of cables and stationary pairs arranged blocks {2.

A disadvantage of this device is its inability to load containers with cargo from bun and kero containers.

The aim of the invention is to provide for the loading of containers with cargoes from bunker tanks. The goal is achieved by the fact that the deflecting blocks of one pair are mounted on the width of the carrier frame, and the other pair of blocks are mounted in a vertical plane extending beyond the contour of the carrier frame.

In this case, the device can be equipped with a device for locking the upper and lower positions of the carrier frame, each of which contains a limit switch and a double-plate lever, one of the arms of which is spring-loaded and interacts with the limit switch and the other between the cables.

Claims (2)

The device comprises a carrier frame 1 suspended on two converging ones. 39 cables 2 under the bunker capacity 3 so that the middle of the frame is located on the central axis of the tank or its discharge nipple. Each converging cable 2 is fixed at one end with the help of oblique cables to the carrier frame and passed through two pairs of stationary deflecting units 5 and 6, and the other end is hung on hook 7 of the lifting mechanism 8, which is installed in the upper part of the room away from the tank. On the supporting frame there are slings 9 with hooks 10, to which the container 11 is stroped. A pair of blocks 5 is spaced and located under the middle part of the frame, and blocks 6 are outside its dimensions. The device is equipped with locking devices, the upper 12 and lower 13. Each locking device consists of a two-arm lever 14, a limit switch 15, a spring 16 and a base 17. A double-arm lever 14 is pressed with a spring 1b to the limit switch 15. Arm 19 is omitted between the cables 2 suspension. The device works as follows. When the lifting mechanism 8 is turned on, its hook 7 moves up or down. In this case, the cables 2, the envelopes 5 and 6 are moved, and the supporting frame 1, respectively, is moved to which it is attached by means of slings 9 and hooks 10 floors 11. Such a suspension allows the carrying frame 1 not only under the bunker capacity, but even higher downstream of the discharge nipple of the tank, which is very important when working in a room with a limited height. If, due to a malfunction, the locking devices of the lifting mechanism itself do not work, then the cable system will reach extreme positions and then locking devices 12 or 13 of the gripping device will work, the lifting mechanism will be disabled and its subsequent activation will be possible only after the fault has been eliminated. The invention makes it possible to mechanize the entire process of loading containers from a storage tank under conditions of a limited height, and the presence of blocking devices increases the safety of operations performed. Claim 1. Capture device for containers, comprising a carrier frame, gripping bodies mounted thereon and a drive for raising and lowering the frame, including a lifting mechanism connected to the carrier frame by means of cables and stationary pairwise arranged blocks, This is due to the fact that, in order to ensure that containers are loaded with cargo from bunker tanks, the deflecting blocks of one pair are installed on the width of the supporting frame, and the other pair of blocks is installed in the vertical | Noah plane going out ely supporting frame contour. 2. The device according to claim 1, of which it is equipped with devices for locking the upper and lower positions of the carrier frame, each of which contains a limit switch and a double-arm lever, one of the arms of which is spring-loaded and interacts with the final switch, and the other is located between the cables.
