Description

The utility model relates to devices designed for mechanization of work related to lifting or moving goods and can be used to pull a stalled car, for individual construction, for other purposes in everyday life.

Known manual winch (Pat.2237007 Russian Federation, IPC7 B66D 1/04. Manual winch / Kutsenko E.N., Azarenkov S.P .; applicants and patent holders Kutsenko Eduard Nikolaevich and Azarenkov Sergey Petrovich, No. 2002117314/11, application. 19.06. .02, published September 27, 04), containing a drum with two cables and a ratchet ring, a bracket with a spring-loaded dog, a drive handle (in the form of a lever) also with a spring-loaded dog. The standard ratchet gear is used to move the load.

The disadvantage of this device is the low speed of movement of the load (regardless of the magnitude of the applied force), the small distance of movement at one time in connection with the adopted system of winding cables onto the drum (there is not enough volume for wound cables), the inconvenience of returning the device to its original position due to the need simultaneous squeezing during this process of two spring-loaded dogs at once.

Known manual winch (Pat. 21116955 Russian Federation, IPC6 B66D 1/04. Manual winch / Kovalev N.A., Kovalev A.N .; applicant and patentee Kovalev Nikolay Antonovich, No. 97110033/28 of the application. 06/13/97, publ. 08/10/98.), Containing a drum with a cable, a rotating handle, an eccentric, a ratchet, bearings, ring gears and grooves on the body.

The disadvantage of the device is the low speed of movement of the load, the complexity of the design, the significant cost of effort to overcome the friction forces in the mechanism.

For the prototype of the proposed device adopted classic winch with a manual drive, including a drum, cable and crank. (Aleksandrov M.P. Lifting machines: Textbook for high schools. -M .: Publishing house of MSTU named after N.E.Bauman - Higher school, 2000.-552 s; s4-20. -10000 copies; ISBN 5- 7038-1516-9; ISBN 5-06-003978-1).

The disadvantage of this mechanism is that it is capable of lifting only a load weighing less than the weight of the winch, as well as the fact that the drum must be located strictly perpendicular to the direction of movement of the transported load, but even when the cable is displaced from the perpendicular at the time of winding onto the drum, there are torques that require mandatory elimination.

The technical result of the claimed utility model is ease of use, the ability to create significant traction.

The specified technical result is achieved by the fact that a motorist’s hand winch containing a drum with a cable and a handle, according to a utility model, is mounted on a U-shaped frame, parallel to the axis of the drum, a crossbeam is installed under it with a round section perpendicular to it, on which a L-shaped is worn a latch for counteracting torques and keeping the device in working position, and cables are attached to the ears placed on the drum shaft bushings, with which the winch is attached to the ground to Vision support, the ratio of the radius of the drum and the length of the handle is designed as a 1: 6 ÷ 10, if necessary doubling of traction are used movable block with a hook fastened on the load, and the cable is passed through the unit and secured to the frame perkladine winch.

The model is convenient in operation since quickly and easily brought to its working position and quickly collapses, allows with acceptable speed and a sufficient distance to move the load. Significant traction is created due to the special ratio of the radius of the drum and the length of the handle. If necessary, a movable block with a hook mounted on the load is used to double traction.

Figure 4 presents a General view of the claimed utility model in the process

The motorist’s hand winch comprises a traction mechanism in the form of a drum 1, rigidly fixed to a rotating bearing shaft 2, with a cable 3, a handle 4 and a hook 5 at the end of the cable. The bearing shaft 2 rotates in the bushings 6, welded to the frame. The handle 4 is located on the end of the shaft, the ratio of the radius of the drum and its length is 1: 6 ÷ 10. On the upper crossbar 7 of the frame in the front part, a console of round cross section 8 is attached, and on the rear hook for the hook 9. During use of the device, a latch 10 is put on the console 8, the length of which exceeds the length of the handle, which serves to hold the winch in working position and to counter the resulting rotating moments. The winch is mounted on the ground with the help of two cables 11, attached to the ears 12, welded to the sleeves 6, and to the fixed support 13. If necessary, increase the traction force using a movable block 14 with a hook.

The manual winch works as follows: the cable 3 is hooked by hook 5 to the load (for example, a car), and the cables 11 to the fixed support 13. The latch 10 is worn on the console 8, the device position convenient for operation is selected. When the handle 4 is rotated with the right hand, the cable is pulled and the load moves. By counteracting the left moments with the help of the lock 10 of the torques and pressing the device to the ground, the winch is held in the same position. When the ratio of the radius of the drum to the length of the handle is 1: 8 and with a force of 25 kg applied to the handle, the pulling force on the cable will be 200 kg. If this effort is insufficient, a movable block 14 is applied and the force is about 400 kg. In this case, the cable 3 with the hook 5 passes through the block 14 and the hook is attached to the hook 9 on the frame.

It should be borne in mind that to prevent high vertical pressure on the frame of the winch, which can immerse it in loose soil, the cables 11 should be mounted away from the winch so that the angle α between the cables and the horizontal (see figure 4) is no more than 20 degrees.

The inventive model provides the following advantages:

- simplicity of design;

- convenience in operation;

- significant traction;

- a sufficiently high speed and distance of movement of the cargo.
