Description

[Detailed description of the invention] (a) Field of industrial application This invention relates to a portable winch that allows the installation of the machine body to be selected from various ways as required, and can be adapted to the conditions of the installation location.

(B) Prior art A conventional portable winch is fixed to the upper surface of a support base having a ground surface, and has drum support walls protruding upward from both sides of a drive case with an engine fixed to the rear. A drum was rotatably accommodated and supported between the support walls, and a rear end of a guide pole having a guide tool for a wire wound around the drum at the front end was provided above the drum. As a result, when performing winch work, first ground the ground surface of the support base on the ground, and then connect the connecting hook at the rear end of the guide pole to the standing tree, etc. behind it using the connecting rope. After connecting the wires from the drum to the front through the guide tool and attaching it to the towed object, the power from the engine is transmitted to the drum through a deceleration mechanism in the drive case, and the drum is driven to rotate. was.

(c) Problems that the invention aims to solve However, there are cases where there are stones, etc. between the aircraft and the towed object, or there is no place to stably ground the aircraft and it is desired to attach it directly to a tree, etc. In such cases, with this type of portable winch, it is difficult to ground the rear end of the drum support wall to increase the lifting angle between the wire and the ground, or to install it on a tree, etc., since the engine protrudes backwards. There were some problems, such as not being able to do it.

(d) Means for solving the problem Therefore, this invention is based on the idea of installing drum support walls facing upward from both sides of the drive case, which is fixed to the top side of the support base having a ground plane and has the engine fixed to the front. The rear end side of the guide pole is provided protrudingly and rotatably accommodates and supports the drum between both drum support walls, and has a guide tool for the wire wound around the drum at the front end. In the installed winch, the longitudinal direction of the guide pole is arranged in the same direction as the ground surface of the support base, and each rear end surface of the drum support wall is the maximum backward surface of the aircraft, and this backward surface One or both of the rear end surface of the drive case and the rear end surface of the support stand are exposed in the vicinity of a vertical plane passing through the vertical plane.

(e) Function With the above configuration, it is possible to not only use the drum with the grounding surface of the support base in contact with the ground, but also with the rear end surface of the drum support wall grounded and the guide pole erected for inverted support. It can also be used by attaching it to a standing tree or the like.

(F) Embodiments Hereinafter, preferred embodiments of this invention will be described in detail by way of example with reference to the drawings.

The portable winch, as shown in Figure 1,
An engine 1, a drive case 2 to which the engine 1 is fixed to the front, a support base 3 to which the lower part of the drive case 2 is fixed to the upper surface, and drums provided upward from both side walls of the drive case 2 to face each other. Support wall 4,
4, a drum 6 that is rotatably supported via a support shaft 5 that is horizontally suspended on both drum support walls 4, 4 so that the axial direction is in both directions, and a wire 7 that is wound around the drum 6. It has a guide tool 8 at its front end, and a guide pole 9 whose rear end is above the drum. The power of the engine 1 is appropriately decelerated within the drive case 2, and is transmitted from the output shaft 10 to the drum 6 via the chain 11, so that the drum 6 is rotationally driven.
Due to this rotational drive, the wire 7 is guided by the guide tool 8 in front and wound around the drum 6 without being irregularly wound. Note that the support stand 3 is preferably a flat one having a ground plane capable of supporting the aircraft body, and in the embodiment, a box-shaped sled is used.
Further, the drum support walls 4, 4 are provided to protrude upwardly from both sides of the upper protrusion of the drive case 2 in an opposed manner, and each of the drum support walls 4, 4 is a pair of drums each having an opening in the center so that the flanges at both ends of the drum 6 can be accommodated therein. Frame 12, 12,
Drum side plates 13, 13 are fixed to cover the outer surfaces of both drum frames 12, 12, fix the support shaft 5, and cover the drum 6 and chain 11 from the outside; The output shaft 10 is protruded in a facing manner and is connected to the lower end edges of both drum side plates 13, 13;
Lower cover 14,1 that covers chain 11 etc.
It consists of 4 magnums (see Figure 2).

By the way, the specific arrangement structure of this portable winch is that first, the support stand 3 and the guide pole 9 are arranged side by side, and the ground plane of the support stand 3 is connected to the guide pole 9.
It is parallel to the longitudinal direction of. This results in
As shown by the solid line in FIG. 1, the contact surface of the support base 3 is grounded on the ground, and the connecting hook 15 at the rear end of the guide pole 9 is connected to a standing tree or the like behind it with a connecting rope 16. Wire 7 via tool 8
When performing normal winch work to wind the drum 6 around the drum 6, the guide pole 9 is positioned parallel to the ground. Next, the rear end surfaces of both drum support walls 4, 4 are arranged so as to be the maximum receding surface of the aircraft, and either the rear end surface of the drive case 2 or the rear end surface of the support stand 3 is placed in the vicinity of a vertical plane passing through this retracting surface. Alternatively, it is arranged so that both sides face each other (in the embodiment, the rear end surface of the drive case 2 is shown facing). As a result, both drum support walls 4, 4,
The longitudinal direction of the guide pole 9 and the direction of the ground contact surface of the support stand 3 with respect to the rear end forming surface R that can support the airframe upside down, which is formed by the rear end surfaces of at least two of the drive case 2 and the support stand 3. are substantially perpendicular to each other, and as shown in FIG. 3, the rear end forming surface R of the fuselage body can be grounded to the ground, and the fuselage can be used by supporting it upside down. At this time, the engine 1 is positioned above the drive case 2, which is advantageous in terms of safety, and the guide pole 9 stands approximately perpendicular to the ground.
Therefore, during the winching operation in which the wire 7 is wound around the drum 6 through the guide tool 8 at the upper end of the upright guide pole 9, a forward moment acts on the upper end of the guide pole 9.
Connecting hook 1 provided at the upper end of the guide pole 9
7 and standing trees etc. are connected with a connecting rope 16 to maintain balance and work can be carried out without any hindrance.

In addition, as shown by the two-dot chain line in Figure 1, the rear end forming surface R of the fuselage can be brought into contact with an upright structure 18 such as a tree, and fixed as appropriate using an attachment rope or the like (not shown). Become.

(g) Effects of the invention This invention, which has the above configuration, allows the ground surface of the support platform 3 to be grounded to the ground, and not only can normal winch work be performed in the same manner as before, but also the lifting angle between the wire 7 and the ground can be improved. In order to increase the size of the machine and enable winch work, the guide pole 9 is raised perpendicular to the ground to support the aircraft in an inverted position. By making contact with one or both of the rear end surfaces of the aircraft, it is possible to stabilize the aircraft, and it is also possible to use the aircraft upside down, which was previously impossible. Furthermore, when the machine is used upside down, the engine 1 is located above the drive case 2, so safety can be ensured. Furthermore, since the rear end surfaces of the drum support walls 4, 4 can be fixed as appropriate by applying them to a standing tree, etc., if there is a standing tree, etc., even in places where there is no ground contact point for the support base 3, winching operations can be performed by attaching it to a standing tree, etc. The range of use can be expanded compared to conventional ones.
