Abstract

PURPOSE:To make it possible to set the positional relationship between a wind- up drum and an electrical power line in a desired condition, by supporting a winding shaft onto which the wind-up drum is fixed, with the use of support columns planted on a base plate which is rotatable around a vertical axis and which may be locked at an arbitrary position. CONSTITUTION:A wind-up device 1 is composed of a pair of support columns 2, a winding shaft 3, a hydraulic motor 4 and a speed change unit 5 for driving the shaft 3, the attaching base 7 of a base plate 6 on which the support columns 2 are planted and a lifter 8 attached to the top ends of the support columns 2. Further, a shaft 10 provided at its top end with a handle 14 is pierced through the center cylindrical section 12 of the base 7, and a fixing pin 14 is fitted between the base 7 and the base plate 6. With this arrangement, when the fixing pin 14 is pulled off and the shaft 10 is loosened, the base plate 6 is made rotatable around the shaft 10 with respect to the base 7, and therefore, the axial direction of the wind-up drum 20 attached to the winding shaft 3 may be directed substantially orthogonal to the direction of an electrical power line.

Description

[Detailed Description of the Invention] [Technical Field] [The present invention is directed to a vehicle loading platform] which is placed on the loading platform of an automobile and is used for recovering electric wires and telephone lines, or for constructing new lines, installing and replacing pillars-1-transformers, etc. This relates to hoisting devices for overhead lines and wires.

1 Background Art 1 A hoisting device for overhead wires and wires is essential for overhead line work vehicles that collect electric wires, telephone lines, etc., or perform work to erect them, or install and replace poles and transformers. ing. This overhead wire work vehicle is used as a winding device, especially a winding device that is equipped with a winding drum for electric wires, and winds the wires on the winding drum and unwinds the wound wires. Conventionally, there are two types: one is installed under the loading platform and the winding shaft to which the winding drum is attached is arranged on the side of the vehicle, and the other is installed on the loading platform L. In conventional products, the axial direction of the winding shaft is fixed to the car, not only in the case of those installed under the cargo bed mentioned above, but also in the case of those installed on the cargo bed. It had become. By the way, when collecting and installing electric wires, is it necessary to make sure that the axial direction of the winding drum attached to the winding device is as perpendicular to the direction of the electric wires to be collected or the electric wires to be installed? Because there are restrictions on the positions where the automatic 11 can be parked, it is rare to be able to perform work while satisfying the above conditions. The axial direction of the winding drum attached to the winding device is fixed to the car as mentioned above, so in addition to the winding device, the electric wire must be placed in the axial direction of the winding drum. A wire guide device that can be switched in orthogonal directions is absolutely necessary, and as a result, the loading platform, which is already narrow due to the large amount of equipment being loaded, has become even narrower.

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to maintain the positional relationship between the winding drum and the electric wire in a desired state without requiring a wire guide device. It is possible to provide equipment for winding overhead lines or wires.

1 Disclosure of the Invention 1 The present invention has a winding drum which is rotatably driven and is attached to a winding drum, and a foot is provided upright from a base plate which is rotatable around a vertical axis and can be fixed at any position. It is characterized by being supported by a support column, and by rotating the base plate, the axial direction of the winding drum attached to the winding shaft can be aligned with the direction of the electric wire. This is what I did. The rotation and fixation of the base plate here may be performed manually, or the base plate may be formed as a gear and connected to a power source such as a motor, and the rotation and fixation may be performed using this power. In addition, in order to facilitate the attachment and detachment of the winding drum to the winding shaft supported by the support, a hanger for the winding drum is provided at one end of the support, and a hanger for the winding drum is installed at one end of the support. It is preferable to set the angle of the erected position to be Mv. It should be noted that, in the following embodiments, the description will be given of a device used for winding electric wires, or it will of course be possible to construct a device for winding three wires.

The present invention will be described in detail below based on the illustrated embodiments.
FIG. 4 shows an embodiment of the present invention,
This hoisting device 1, which is installed on the loading platform 2 of a vehicle used for overhead line work, consists of a pair of supports 2 whose upper ends are connected to each other, and a hoisting device 2 whose outer peripheral surface is a spline and which is disposed between the two branches 2. A take-up shaft 3, a hydraulic motor 4 and a speed reducer 5 for driving the take-up shaft 3, a base plate 6 having a circular planar shape on which both branches 2 are erected, and are fixed on a loading platform. A mounting base 7 to which a base plate 6 is attached on two sides, and a lifting device 8 installed at the upper end of the column 2
It is composed of. The hydraulic motor 4 and the speed reducer 5 are provided coaxially with the winding shaft 3 and are also installed between the two branch offices 2. The hoist 8 has a horizontal movable part 15 that is movable in a horizontal direction parallel to the winding shaft 3, and a horizontal movable part 1.
A vertical movable part 16 is provided at the tip of the vertical movable part 16 and is movable in the vertical direction, and a shaft 4 is supported at the center by the lower end of the vertical movable part 16, and a balance rod 1 has a chain 18 suspended from both ends.
7, and the horizontal movable part 15 and the vertical movable part 16 are made to move by turning a handle 19, respectively. Incidentally, the balance rod 17 and the chain 18 having a groove 77 at the lower end can be removed from the vertical movable part 16.

Now, both branches 2, which have a hanging type 8 at the upper end and a winding shaft 3 and its driving power in the middle, are installed upright from the base plate 6, which is clear from Figure 1. As shown, a shaft 10 having a handle 11 at the upper end and screwed into a cylindrical portion 12 at the center of the base 7 passes through the center, and a surface is formed between the lower surface of the base plate 6 and the peripheral portion of the base 7. A thrust bearing 13 is disposed between the base plate 6 and the base 7, and a fixing pin 1 is disposed around the base plate 6 and the base 7.
A hole into which 4 is inserted is provided. A large number of these holes are provided at equal intervals.

However, in the hoisting device 1, by removing the fixing pin 14 and loosening the shaft 10, the base plate 6 can freely rotate relative to the base 7 around the shaft 10, that is, around the vertical shaft 1]. As shown in FIG. It can be fixed in that direction by inserting the fixing pin 14 into the holes provided in the base plate 6 and the base 7 and tightening the pongee 10.

To explain the mounting structure of the winding drum 20 on the winding shaft 3, among the flanges 21 fixed to both end surfaces of the winding drum 20, one of the flanges 21 has a fitting that connects to the spline of the winding shaft 3. A joint 22 is provided, and a tsuba 21 of ability is provided.
A hollow shaft 23 passing through the inside of the winding drum 20 is screwed onto the winding drum 20. After mounting this hollow shaft 23 on the winding tram 20,
The above-mentioned fitting part 22 is connected to the winding shaft 3, and the tip of the retaining screw 24 passed through the hollow shaft 23 is screwed into the front end surface of the winding shaft 3, thereby tightening the winding drum 20. This is to attach it to the winding shaft 3. Winding drum 2
0 from the winding shaft 3 is performed in the reverse order. When attaching and detaching the winding tram 20, the hoist 8 can be used. By hooking the hooks at the lower ends of both chains 1 and 3 onto the flange 21 and moving the vertically movable part 16, the winding drum 20 can be lifted or suspended, and by moving the horizontally movable part 15, the winding can be lifted. In the axial direction of the take-up shaft 3, the take-up drum 2 (
) can be moved. Incidentally, the amount by which the horizontal movable portion 15 is moved during this attachment and detachment is smaller than the amount required to fit the winding shaft 3 and the fitting portion 22 together.

As shown in FIG. 4, since the winding drum 2 () is suspended by a chain 18 from both ends of a balance rod 17 whose center is pivotally supported, the winding drum 20 can be easily tilted. This is because this point can be utilized for fitting the rolled-up shirt 13 and the fitting portion 22 and removing the material.

Examples of ponds are shown in FIGS. This is lined up at 1.
When arranging each base end of the support column 2 on the left and right sides of the base plate 61, the branch 2 is made rotatable in the vertical plane and one end is connected to the base plate 6 using a hydraulic cylinder 30. piston rod 3
1 is connected to a support 2 to make the angle at which the support 2 stands from the base plate 6 variable. A gear 35 is connected to the motor 33 via a reducer 34 and is meshed with the base plate 6.
By rotating the base plate 6 and locking the rotation of the base plate 6 from the motor 33 side, the winding drum 20 can be mounted by changing the angle of the support 2. ” The second method is one that can be performed without requiring any work. still,
In this embodiment, the winding shaft 3 to which the winding drum 20 is mounted is driven by transmitting output from a motor 4 and a speed reducer 5 arranged at the base end of each of the two pairs of struts 2 to the struts 2.
A chain (not shown) disposed inside is used to guide the pinion 37 at the tip of the pillar 2, and a gear 3 provided at one end of the winding shaft 3.
8- is achieved by meshing the pinion 37 with the pinion 37. The winding shaft 3 here is mounted on the winding drum 20 and then installed in a bearing portion at the tip of the support column 2.

As described in "Effects of the Invention 1 and 2", in the present invention, by rotating the support around the vertical axis, the axial direction of the winding shaft and the winding drum can be centered so as to match the direction of the electric wire or the wire. Therefore, overhead line work can be carried out without requiring a separate shed for electric wires and wires.
