Abstract

The invention relates to a lifting and transport equipment, in particular to devices for lifting and unloading boxes. The aim of the invention is to improve the reliability and convenience of operation. The device includes lifting lines 1 and opening lines 2 with gripping elements 3, suspension 4 with pulleys 8 fixed on it, through which lifting lines 1 are slinging fixed by rod 9 with rectangular A cross section in the central part and a handle 10 with a stopper 11. When the slings 1 and 2 are hooked by the gripping elements 3, the slope of the lifting lines 1 is selected for the box 14 and is fixed by the rod 9 in a tensioned state, the handle 10 is sterr When this is lifted, the handle 10 is released from the stopper 11, and the rod 9 is held in its working fixing state by the tensioned lines 1. When installing the box 14 on the support, the lines of the lifting 1 weaken, the rod 9 under the weight of the handle 10 rotates and releases the lifting straps 1, which during the subsequent lifting of the duct 14 rotate freely on the pulleys 8, and the duct 14 is opened by the straps 2. 2 Cp., 1 sludge. i cl

Description

The invention relates to lifting and handling equipment, in particular, devices for lifting and unloading a duct.

The aim of the invention is to improve the reliability of operation and ease of operation.

The drawing shows the device, a general view.

The device comprises lifting lines 1 and 2 opening, gripping elements 3 mounted on one ends of the lines, suspension 4, with which opening 2 lines are connected. Suspension 4 includes cheeks 5 interconnected by axes 6 and having coaxial holes 7. On axis x 6 fixed pulleys 8, bending around the lifting lines 1, which are sagging

9 clamped by the stoppers 1 under the influence of the load.

When the bottom of the box 14 touches the floor of the car or the already piled mass of the lifting line 1 weakens and the rod 9 is rotated by planes perpendicularly horizontal under the weight of the handle 10 and releases the lifting lines 1. The box 14 rises again, the sling rotates freely on the pulleys 8, the box with the help of the sling 2 is opened.

Claims (3)

1. A device for lifting and unloading a duct containing lifting and opening slings connected to a suspension for a lifting hook 25 It is interconnected by other con-20 mechanisms, and gripping elements, in different ways. At the same time, in the holes 7 of the cheeks 5 placed on the free ends of the x lines, there is a rod 9 having a rectangular section in the central part, on one end of which, on the outside of one of the cheeks 5, a handle 10 is fixed with a stopper 11 of its working position, equipped with a control cable 12. In this case, the lifting lines 1 are provided with limiting devices 13 for moving them, located on the side of the gripping elements 3. The device is gripped by the gripping elements 3 to the duct 14. The proposed device works thirty characterized in that, in order to increase reliability and ease of operation, the suspension includes vertical cheeks interconnected by horizontal axes symmetrically located relative to the vertical axis of symmetry of the cheeks, and made with coaxial holes arranged. between the axes on the aforementioned vertical axis of symmetry of the cheeks, mounted on the said axles are pulleys, which are twisted by lifting lines connected to each other with a sagging, and the device is equipped with a rectangular section in the apertures of the cheeks a rod for fixing the lifting slings in the working position, and a rod fixed on one of the condas on the outer side of the corresponding cheek with a handle with a stopper of its working position. in the following way. Hooking all the lines 1 and 2 to the box 14, the worker selects the slack of the lifting line 1 to the stops 13. Then using the handle 10 rotates the rod 9 to the working position with the planes parallel to the horizontal (see drawing) and fixes the handle 10 in the upper position With the help of a hundred pores. At the beginning of lifting, the sling 1 is finally tensioned and abutted in the lower plane of the rod 9. After that, the worker uses the cable 12 to pull the stopper 11 and release the handle 10, which is now held in its original position by , what rod of VNIIPI Order 1491/20 Circulation 721 Subscription Proizv.-poly. pr-tie, g, Uzhgorod, st. Project, 4 9 clamped by the stoppers 1 under the influence of the load. When the bottom of the box 14 touches the floor of the car or the already piled mass of the lifting line 1 weakens and the rod 9 is rotated by planes perpendicularly horizontal under the weight of the handle 10 and releases the lifting lines 1. The box 14 rises again, the sling rotates freely on the pulleys 8, the box with the help of the sling 2 is opened. Invention Formula 1. A device for lifting and unloading a duct containing lifting and opening slings connected to a suspension for a lifting hook mechanism, and the gripping elements, placed on the free end of the x lines, characterized in that, in order to increase reliability and ease of operation, the suspension includes vertical cheeks interconnected by horizontal axes symmetrically located relative to the vertical axis of symmetry of the cheeks, and made with coaxial holes arranged. between the axes on the aforementioned vertical axis of symmetry of the cheeks, pulleys mounted on the said axes, bending around the lifting lines, interconnected by other ends with sagging, and the device is equipped with a rectangular section in the apertures of the cheeks for fixing the lifting slings in the working position, and fixed on one of the cond rods on the outer side of the corresponding cheek with a handle with a stopper of its working position. 2. The device according to claim 1, characterized in that the handle stopper is made with a control cable. 3. The device is in accordance with claim 1, characterized in that the lifting lines are made with restraints on their movement, space1 on the branches x from the side of the gripping elements.
