The hook clip KS-3578.63.300 (18A) includes a casing that does not allow the rope to exit the block stream, when the rope is loosened or pinched between the inner section of the casing and the outer part of the block, crane blocks that rotate synchronously with the upper blocks located on the frame carts and a rope that creates a polyspast, forged hook, resting on a thrust bearing connected by an axis with a hinged fastener with a fork.

Known suspension hook main automotive crane KS-45717A-1 (http://sinref.ru/000_uchebniki/02700krani/012_kran_strelovoi_avto_ks_45717a_1_rukovodstvo/018.htm, Crane jib KS-45717A-1-k. -154--154-A-1-kr-156-A-1-kr-157-kt-45717A-1k ), selected by the applicant as the closest equivalent. The main hook suspension is designed to operate a crane with a telescopic boom with eight and five times the stock of a cargo rope. The suspension consists of two cheeks, working units installed between them, rotating on rolling bearings on an axis and fixed by spacers, traverses, on which a hook is mounted on a thrust bearing. From falling out of the rope, the blocks are fenced with rod-shaped stops.

In the known solutions of hook hangers, the end of the load rope is secured with a wedge yoke. Usually, to change the multiplicity of stocking of the cargo rope, its end is removed from the wedge holder (for which it is necessary to remove the clamp on the rope and knock the rope with the wedge out of the wedge holder body), and after changing the multiplicity of the stocking, it is necessary to re-fasten the end of the cargo cable in the wedge holder, put a loop of rope with a wedge in it into the body of the wedge holder, then install a clamp on the rope, which is quite a laborious process, during which damage to the rope may occur. To perform the work requires a variety of tools: wrenches of various sizes, pliers, hammer, a special hammer for a wedge.

The technical problem solved by the utility model is the expansion of the arsenal of technical means, namely, hook hangers for an automobile crane.

The technical result is the creation of a device that simplifies and speeds up the process of changing the frequency of stocking a cargo rope, reducing the likelihood of damage, reducing the range of tools used.

The technical result is achieved due to the fact that in the known device of the suspension hook, including two cheeks placed between the bypass blocks mounted on an axis for rotation, the streams of which stretch the rope, the end of which is fixed in the wedge yoke, and installed between the cheeks along the contour blocks security elements from falling off the rope movably mounted between the hook with cheeks crosspiece according utility model, protection elements are provided with quick-fastening, in the lower cheek portions are rectilinear teaching Stacks forming the supporting surface of the hook suspension, between the bypass blocks and the crosshead with the hook in the “lateral” position, a “window” is formed, the width and height of which is more than the corresponding dimensions of the wedge yoke by at least 10 mm in each dimension.

The presence of several bypass units installed on the axis with the possibility of rotation, allows you to change the multiplicity of the reserve rope in the process of the crane.

The fastening of the rope in the wedge yoke allows you to securely fix the end of the rope.

The presence of elements between the cheeks along the contour of the blocks of elements of protection against the falling of the rope provide reliable protection of the rope from leaving the block stream during operation.

The presence of quick-release fastenings of protection elements to the cheeks ensures their quick disassembly and installation in the process of changing the frequency of storing the rope without using a tool, which eliminates the need for pulling the rope along the streams of blocks limited by the protection elements, speeds up and simplifies the process of changing the stock.

Performing in the lower part of the cheeks straight sections that form the supporting surface of the hook suspension allows you to securely install the hook suspension with support on the specified surface in the process of changing the rope stockpile, which speeds up and simplifies the procedure for changing the frequency of rope stocking.

The presence of a window formed between the bypass blocks and the hook with the crossbar in the “lateral” position allows you to pull the rope between the hook and the bypass blocks without removing the rope from the wedge cage, and making the window width and height more than the corresponding dimensions of the wedge cage not less than 10 mm along each size provides free passage of the wedge yoke through the “window” along with the rope, which helps to simplify and speed up the process of changing the multiplicity of stocking of the cargo rope.

The above features allow you to create a device of a hook suspension, which simplifies and accelerates the process of changing the frequency of stocking the cargo rope.

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a general view of the hook suspension; FIG. 2 - hook suspension mounted on the ground, side view, in FIG. 3 is a general view of the hook suspension at the time of changing the stocking of the cargo rope (with overall dimensions, an example of a specific embodiment); FIG. 4 - a general view of the hook suspension mounted on the boom (example of a specific implementation).

Hook suspension (Fig. 1) includes two cheeks 1 with bypass blocks 2 placed between them, mounted on axis 3 with the possibility of rotation, through which the rope will extend. The free end of the rope is fixed in the wedge holder 4 (Fig. 3). Between the cheeks 1 along the contour of the blocks 2, there are installed elements of protection 5 against falling of the rope (Fig. 1), equipped with a quick-release fastening 6 to the cheeks 1. The straight-line sections in the lower part of the cheeks 1 form the supporting plane of the hook suspension. A hook 7 with the crosspiece 8 is movably fixed between the cheeks 1 below the bypass blocks 2. Between the bypass blocks 2 and the hook with the cross bar in the “lateral” position a “window” is formed (FIGS. 2, 3) whose width and height are greater than the corresponding dimensions of the wedge yoke 4 not less than 10 mm in each size.

The change in the multiplicity of spare freight rope is as follows.

The hook suspension is lowered onto a flat horizontal surface (on the ground) and installed on the supporting surface formed by the lower straight sections of the cheeks 1, ensuring a stable and safe position of the suspension in the process of changing the frequency ratio of the cargo rope. When this hook 7 is placed in the position "sideways" (Fig. 2, 3). In this position, between the bypass blocks 2 and the hook with the crossbar, a “window” is formed, the size of which allows the wedge holder 4 with the rope to pass through it without releasing the end of the rope from the holder. Dismantle the quick-release fasteners and remove the protection elements 5 from the falling of the rope on the hook suspension and on the boom tip. The wedge yoke 4 with the end of the rope fixed in it is dismantled from the point of its fastening (on the boom tip or on a hook suspension). The rope, the end of which is fixed in the wedge holder, together with the wedge holder 4, is pulled through the “window” between the bypass blocks 2 and the hook and installed along the bypass blocks 2 in accordance with the required reserve pattern. After installing the rope, the protection elements 5 are again fixed on the boom tip and cheeks 1 with the help of quick-release fasteners 6. The wedge holder is fixed on a regular place (on the boom tip or on a hook suspension). In the exemplary embodiment of the device shown in FIG. 4 wedge holder 4 attached to the tip of the boom.

An example of a specific embodiment of the device is represented in the drawings of FIG. 1-3. Hook suspension includes two cheeks 1 with bypass blocks 2 placed between them, mounted on axis 3 for rotation and fitted with streams through which a rope is stretched. The free end of the rope is fixed in the wedge yoke 4. Between the cheeks 1 along the contour of the blocks 2, there are protection elements 5 against falling of the rope, which are rods, each of which is equipped with a quick-release fastener 6. Between the bypass blocks 2 and the hook 1 with a cross-arm in the side position "Formed a" window. The height of the window is 92 mm, width - 234 mm, while the overall dimensions of the wedge holder with the end of the rope fixed in it are 61 × 134 mm, that is, the wedge holder 4 with the rope can freely pass through the resulting window without releasing the end of the rope from the holder 4 for Changes in the multiplicity of rope storing.

A specific example illustrates a particular case of the device and is given to explain the essence of the proposed technical solution. A specific example does not limit the size of any structural elements.

The proposed design of the hook suspension provides a change in the multiplicity of stocking the cargo rope without releasing the end of the rope from the wedge holder.
