Description

  The present invention relates to an anti-theft device used to prevent the large generator from being stolen.

  Large generators used at construction sites are heavy and are always left on site during the construction period.

  By the way, recently, theft of large generators is increasing, and a means for preventing theft is desired. However, as far as the applicant of the present invention can know, there is no prior document information about the means for preventing theft.

  The present applicant aims to prevent theft of a large generator while reducing the influence on the large generator, and an object of the present invention is to provide an antitheft device that solves this problem.

The technical means adopted by the present invention to achieve the above object is an anti-theft device for preventing the theft of a large generator, which is mounted on the large generator and above a movable part of a construction machine. A large power generator is set in an immobile state by a pushing force from the power generator. (Claim 1)
The construction machine referred to here includes, for example, all machines having at least a vertically movable unit such as a shovel car or a bulldozer.
The movable part is a bucket or the like provided in the construction machine. The movable part places the bucket above the mounted anti-theft device and applies a pushing force to the anti-theft device.

In addition, the greater the pressing force of the movable part, the higher the effect of preventing theft. However, if the pressing force is too large, it may affect a large generator.
Therefore, from the viewpoint of making the large generator immobile even with a small pressing force, it is preferable to provide a fitting part with which the movable part fits (claim 2).
Further, from the viewpoint of immobilizing the large generator even with a small pressing force, a holding plate for holding down the side of the large generator is erected, and the holding plate is attached to at least the two sides facing the large generator. It is preferable to press the portion (claim 3).

  Further, from the viewpoint of reducing the influence of the pressing force of the movable portion on the large generator, it is preferable to provide a cushion material on the contact surface with the large generator (claim 4).

According to the invention of claim 1, since the anti-theft device is mounted on the large-sized generator and the pushing force of the movable portion is applied from the anti-theft device, damage to the large-sized generator can be prevented. After suppressing the influence, the large-sized generator can be brought into the immobile state.
Therefore, the theft of the large generator can be prevented while reducing the influence on the large generator.

Further, according to the invention of claim 2, since the movable part is fitted into the fitting part, the horizontal displacement of the anti-theft device is prevented, so that the anti-theft device is not removed.
Therefore, even if the pressing force of the movable part is small, the contact state of the anti-theft device with the large generator is securely maintained to keep the large generator immobile, and the influence of the pressing force on the large generator is further reduced. It can be suppressed effectively.
Further, according to the invention of claim 3, since the side portion of the large generator is pressed by the holding plate to prevent the horizontal displacement between the anti-theft device and the large generator, the pressing force of the movable portion is reduced. Even if the size is small, the contact state of the anti-theft device with the large generator can be reliably maintained, the immovable state of the large generator can be maintained, and the effect of the holding force on the large generator can be more effectively suppressed. .
Furthermore, according to the invention of claim 4, since the pressing force of the movable portion is absorbed by the cushion material, the influence of the pressing force on the large generator can be more effectively suppressed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show a state in which the anti-theft device C of the present invention is mounted on the large generator A, and FIG. 2 shows a state in which the movable portion B is mounted on the anti-theft device C. ing.

  The anti-theft device C of the present embodiment includes a contact plate 1 that contacts the upper surface of the large generator A, a fitting portion 2 on which the movable portion is mounted in a fitting manner, and a lower surface of the contact plate 1. A holding plate 3 is provided at both edges along the longitudinal side of the large generator.

The contact plate 1 is a rectangular flat plate having a short side parallel to the long side of the large generator A and a long side parallel to the short side of the large generator A.
The fitting portion 2 is a concave portion formed on the contact plate 1 by a side wall 21 rising at the peripheral edge of the upper surface of the contact plate 1, and the movable portion B is fitted into such a fitting portion 2 and ,
The holding plate 3 is vertically provided at a position such that a cushion member 4 described later is in close contact with the side surface of the large generator A.

More specifically, two reinforcing rods 11 are provided on the upper surface of the contact plate 1 between the side walls 21.
In addition, four drain holes 12 are formed on the upper surface of the contact plate 1, and a net 13 is formed in the drain holes 12.
Further, the above-described cushioning material 4 is attached to the lower surface (hereinafter, referred to as “contact surface”) 14 of the contact plate 1 and the back surface (hereinafter, referred to as “contact surface”) 15 of the pressing plate 3 so as to be scattered. ing.
The cushion material 4 is formed of a rubber material or a soft synthetic resin material in a plate shape, and the elasticity of the cushion material 4 absorbs the pressing force of the movable portion B, and the large power generator by the pressing force. Suppresses the effects of scratches on the surface.
On one side of the side wall 21, there is provided a hooking portion 22 on which the distal end portion B 1 of the movable portion B is hooked. , The fitting state of the movable part B to the fitting part 2 is more reliably held.
Reference numeral C1 is a hook for hanging a rope, a chain, or the like used when suspending the antitheft device C.

According to the anti-theft device C thus configured, the anti-theft device C is set on the large generator A, and the front end portion B1 of the movable portion B is hooked on the hook 22 of the anti-theft device C. The movable part B is fitted to the fitting part 2.
At this time, the movable unit B is moved in the descending direction, and the pushing force due to the descending is applied to the large generator A via the anti-theft device C, whereby the large generator A can be fixedly held.

Note that, in the present embodiment, the mode in which the pressing plate sandwiches the two side surfaces of the large generator is illustrated, but as another mode, the pressing plate is provided over the entire circumference of the large generator. It is good also as the aspect provided. (Not shown)
In this case, as an aspect of the contact plate, as exemplified in the embodiment, an aspect may be such that the contact plate contacts a part of the upper surface of the large generator, or may contact the entire upper surface of the large generator. It is good also as an aspect. (Not shown)
Also,

  It should be noted that the present invention is not limited to the illustrated embodiment, and other configurations can be implemented without departing from the scope of the claims of the utility model registration.

The perspective view showing the state where the anti-theft device concerning the present invention was set. FIG. 2 is a sectional view taken along line (2)-(2) of FIG. 1. FIG. 2 is a sectional view taken along line (3)-(3) of FIG. 1.
