Description

Winch jack {a jack combine winch}

The present invention relates to a jack (Jack), and more particularly, can be used as a winch (Winch), and relates to a winch combined jack that can be folded and easy to carry and store.

As is well known, the jack is a tool for lifting heavy objects using the principle of lever or hydraulic pressure. These jacks are mainly mechanical jacks using the principle of lever or screw, and hydraulic jacks using compressed oil. Mechanical jacks are used to lift small, relatively light objects, and hydraulic jacks are designed to lift objects heavier than mechanical jacks.

Mechanical jacks include screw jacks, rack drive jacks, and the like, and among them, screw jacks that are easy to operate, convenient to carry, and relatively small in recent years have been used. The screw jack has a threaded operating rod, and a pair of upper arms and a pair of lower arms, which are opened or retracted while being lifted and lowered in accordance with the rotation of the operating rod, is installed on the screw part. Have

By this configuration, the upper arm and the lower arm are opened by rotating the operation rod with a separate turning rod, thereby allowing the upper arm to lift the object. In recent years, a small passenger car is inevitably equipped with a screw jack having such characteristics.

On the other hand, the screw jack having such a configuration, although the size is smaller than the hydraulic jack or rack drive jack, there is still a disadvantage that the weight is heavy and bulky for the elderly or women to operate. In particular, not only the length of the working rod is long, but also the drawback of uncomfortable storage is extended long when the upper arm and the lower arm folded. Therefore, it is required to develop a technology to further reduce the size of the jack and light weight.

Based on these demands, the inventors have developed a lightweight and miniaturized jack to solve the conventional shortcomings. In addition, the present inventors have developed a winch combined jack that can be expected to achieve a different effect from the conventional by adding a function of the winch to attract the heavy weight in addition to the inherent function of the jack for lifting the heavy object not satisfied with this.

Accordingly, an object of the present invention is to provide a winch combined jack to reduce the size of the jack and reduce the weight to simplify the operation and convenient storage.

Another object of the present invention is to provide a winch combination jack that can perform the function of the winch as well as the jack.

First, as shown in Figure 1 it can be seen that the winch combined jack of the present invention is largely composed of a base (10) and the operating arm (40) foldable to the base (10).

Looking at this in detail, the winch jack jack of the present invention has a pedestal (10). The pedestal 10 consists of a pair of fixing plates 12 facing each other and a connecting plate 13 connecting the pair of fixing plates 12. A coaxial through-hole 15 is formed at one side of the fixing plate 12 facing each other, and an extension portion 16 extending from the fixing plate 12 is formed at an upper portion of the through-hole 15. Here, the fixing plate 12 should have sufficient strength to sufficiently support the load of the heavy material.

On the other hand, one of the extending portion 16 is formed with a pair of protruding pieces (17) facing each other in the longitudinal direction of the fixing plate 12, the rotary piece (17a) is formed in the protruding piece (17) have. The rotating hole 17a is configured to be coaxial in the longitudinal direction of the fixed plate 12. In addition, the other side of the fixing plate 12, the hook 18 is installed to be rotatable by a separate fastener (19).

In addition, the drive shaft 20 is rotatably installed in the rotation hole 17a of the protruding piece 17. The drive shaft 20 is installed to protrude to one side while penetrating the rotary hole 17a of the protruding piece 17, the protruding one side is formed in a square so that the ratchet wrench (W) and the like can be fitted.

In addition, the driven shaft 22 is rotatably fitted in the through hole 15 of the pedestal 10. The driven shaft 22 is rotated by the drive shaft 20 of the pedestal 10, and is configured to intersect the drive shaft 20 at a predetermined interval. In addition, a fixed groove 22a is formed at one side of the driven shaft 22, and this fixed groove 22a is a place where the wire 50 is fixed when the present invention is used as a winch. This will be described later.

On the other hand, the drive shaft 20 and the driven shaft 22 intersected at a predetermined interval is provided with a worm gear 30 for transmitting the driving force of the drive shaft 20 to the driven shaft 22. The worm gear 30 is composed of a worm 32 and a worm wheel 34, the worm 32 is installed on the drive shaft 20, the worm wheel 34 is installed on the driven shaft 22. This is to prevent the rotational force of the driven shaft 22 from being transmitted to the drive shaft 20 upside down.

By this configuration, the driving force of the drive shaft 20 is transmitted to the driven shaft 22 through the worm 32 and the worm wheel 34, and thus the driven shaft 22 can be rotated.

And the actuating arm 40 is fixed to the driven shaft 22. The actuating arm 40 comprises a first actuating arm 42 having one end fixed to the driven shaft 22 and a second actuating arm 44 which can be connected to and detached from the first actuating arm 42. It is composed. The first operating arm 42 is composed of a pair of opposing support plates 42a and a connecting plate 42b connecting the support plates 42a, and an assembly hole constituting a coaxial shaft on one side of the opposing support plates 42a. 42c is formed. As shown in FIG. 3, the driven shaft 22 is fitted into this assembly hole 42c, and is welded and fixed. Thus, the first operating arm 42 can be naturally rotated together with the driven shaft 22. Here, the first operating arm 42 should be configured to be freely rotatable without causing interference with the connecting plate 13 connecting the fixed plate 12 of the pedestal 10. This is to prevent the rotation of the drive shaft 20 when using the present invention as a winch. This will be described later.

The second operating arm 44 is composed of a pair of support plates 44a facing each other and a connecting plate 44b connecting the support plates 44a, similarly to the first operating arms 42. This second operating arm 44 is assembled to the first operating arm 42 by bolts and nuts so that it can be connected to and disconnected from the first operating arm 42. On the other hand, the operation arm 40 is configured to have a smaller width than the pedestal 10 so that it can be overlapped with the pedestal 10, and like the pedestal 10 has a sufficient strength to firmly support heavy objects Must have

Therefore, by such a configuration, the operation arm 40 is installed to be foldable on the pedestal 10 as well as to be rotated from the pedestal 10 by an external force to lift the heavy object upwards.

On the other hand, with reference to Figure 4 looks at the use example of the present invention used as a jack. 4 is a view showing when lifting a heavy chain vehicle. First, the jack of the present invention is disposed between the ground and the vehicle body of the vehicle 1 in a state where the pedestal 10 and the operation arm 40 overlap. Then, by rotating the drive shaft 20 installed on the pedestal 10 using a separate rotation means, the rotational force of the drive shaft 20 is transmitted to the driven shaft 22 through the worm gear 30, the driven shaft 22 ) Is rotated. And while operating the arm 40 is fixed to the driven shaft 22 is also to lift the vehicle 1 to the top. Here, since the drive shaft 20 and the driven shaft 22 are connected to each other by the worm 32 and the worm wheel 34, the reverse rotation of the operating arm 40 is prevented, whereby the operating arm 40 is an automobile It can keep the state which supported (1) continuously.

On the other hand, the rotation means for rotating the drive shaft 20, as shown in Figure 1 it is preferable to use a bidirectional ratchet wrench (W) to facilitate the operation of women and the elderly.

On the contrary, when the lifted vehicle 1 is lowered, the drive shaft 20 is reversely rotated using the ratchet wrench (W). Then, the driven shaft 22 is also reversely rotated, and at the same time, the operating arm 40 in the standing state is also rotated downward and is folded into the pedestal 10. And the vehicle 1 lifted in this state is to be naturally seated on the ground.

Next, with reference to Figures 1 and 5 looks at the configuration of the subject innovation when used as a winch. First, in order to use the present invention as a winch, the second operating arm 44 must be separated from the first operating arm 42. This is to prevent the interference between the operation arm 40 and the connecting plate 13 of the pedestal 10 to smoothly rotate the driven shaft 22. Then, one end of the wire 50 is fixed to the fixing groove 22a of the driven shaft 22, and the wire 50 is wound around the driven shaft 22.

The present invention having such a configuration as shown in Figure 5 to secure the hook 18 of the pedestal 10 to the fixed body 3, the wire 50 is fixed to the weight object tow object (1), As with the jack, the drive shaft 20 is rotated using a ratchet wrench. Then, the rotational force of the drive shaft 20 passes through the worm 32 and the worm wheel 34 to rotate the driven shaft 22. The driven shaft 22 rotated in such a state can pull the tow object 1 while winding the wire 50.

On the other hand, in order to further increase the traction force, the pulley 5 is installed on the tow object 1, the wire 50 is wound around the pulley 5, and its end is fixed to the extension 16 of the pedestal 10. Next, the wire 50 may be pulled back and towed.
