Description

[Detailed description of the invention] Industrial field of application The invention relates to a wire rope transport and unwinding machine for transporting a coiled wire rope to a place of use, pulling out the wire rope, and performing unwinding operations. be.

Conventional Technology Conventionally, coiled wire rope has been transported by loading the coiled wire rope and unwinding machine from a storage location onto a vehicle using a crane, hoist, etc., and transporting the coiled wire rope to a use location.

Regarding the unwinding of wire rope, the wire rope is coiled or wound around a main frame (drum) when delivered, but it is important to note that the rope may become twisted or untwisted when the rope is unwound. Care must be taken to ensure that this does not occur. For this reason, when unraveling a rope, as shown in Figure 3 A, a rope wrapped in a wooden frame (drum) should be able to rotate by passing a rod through the center hole, and a coiled rope should be able to be rotated by passing a rod through the hole in the center.
Prepare a rotating table that fits the center hole as shown in the figure,
The correct way to unravel (pull out) is to place it on top of it and pull it out. Another correct method is to roll the coil itself and pull it out without twisting the rope, as shown in Figure C.

If there is no suitable wooden frame at the work site,
As shown in Figure D, there is also a method of placing a rope on top of the cross frame C, suspending it from a three-pronged block d with a swivel, and pulling out the rope.

If a coiled wire rope is pulled out incorrectly, the rope will become twisted or untwisted, causing kinks and deformation, which will significantly shorten the life of the rope.

Problems that the invention aims to solve Due to the above-mentioned problems, the coiled wire rope and the unwinding machine are transported separately to the place of use, and the rope is set in the unwinding machine at the site. However, since coiled wire rope does not have a core like a wooden frame, it was impossible to move it by rolling it, so it had to be moved by cranes, hoists, etc. In addition, it is difficult to transport the rewinding machine manually, and it takes time to prepare the work, as it has to be carried by a crane or hoist, and depending on the location, several people have to move it, and it is difficult to easily move the set wire rope to the desired position. There were problems such as not being able to move.

Means for Solving the Problems The present invention aims to solve these problems, and will be explained below using FIGS. 1 and 2 as a preferred embodiment of the present invention. A fixed-side bearing bracket 5 that is fixed upright and a retractable-side bearing bracket 6 that stands up by a pivoting part 7 at the root and a safety device 11 such as a stopper are spaced apart from each other on the upper surface of the base plate 8 in the form of a thin frame plate. One side plate/wheel 1 side of the winding frame 3 is mounted on a fixed bearing bracket 5, and the winding frame 3 can be freely removed using the other mounting screw 4.
The end of the shaft 3a on the side plate/wheel 2 side attached to the side plate is mounted on the upper end notch 6a of the retractable side bearing bracket 6,
During transportation, the casters 10, 10 attached to the side edges 9, which will be the lower side of the platform 8, and the side plates/wheels 1,
This is the configuration of a wire rope conveying and rewinding machine that can be rolled by.

Function The present invention uses the above-mentioned means to set the wire rope by tilting the retractable side bearing bracket 6 in the direction of the arrow of the phantom line from the state shown in FIG. Remove the side plate/wheel 2 on the removal side. Next, the coiled wire rope W is fitted into the winding frame 3 and set (a detent is also set so that the wire rope bundle does not move).
Then, the side plate and wheel 2 on the retractable side is attached and fixed to the winding frame 3 with the mounting screws 4, the retractable side bearing bracket 6 is erected, and the end of the shaft 3a is placed on the frame, and the safety device 1 is mounted.
Multiply by 1 to complete the setting work.

After setting the wire rope, raise the machine so that the casters 10, 10 are facing down, place your hands on the base plate 8, and push it like a handcart as shown in Fig. 2.
It is transported to a destination by rolling it using casters 10, 10 and side plates/wheels 1, 2, and the casters 10, 10 change direction. Since the wire rope W is set on the winding frame 3, the rope can be pulled out and rewinded easily and smoothly.

Example An embodiment of the present invention will be described below.

In FIG. 1, reference numeral 1 denotes a side plate and wheel on the fixed side of the winding frame, and a rope receiving frame 3 is attached thereto. Reference numeral 2 denotes a side plate/wheel on the removable side of the winding frame 3, which is removably attached to the winding frame (body) with a mounting screw 4. Reference numeral 5 denotes a fixed side bearing bracket for supporting the fixed side plate and wheel 1 side of the winding frame 3, and is provided upright integrally on the upper surface of the base plate 8 having a rectangular frame plate shape. Reference numeral 6 denotes a retractable side bearing bracket provided on the base plate 8 opposite to the fixed side bearing bracket 5, and the root portion is located on the base plate 8.
On the upper side, there is provided a pivot portion 7 which is movably connected by a hinge fitting or the like, and on the opposite side there is provided a safety device 11 such as a stopper for holding the retractable side bearing bracket 6 in an upright state. Reference numeral 6a denotes a notch provided at the tip of the retractable bearing bracket 6, on which the end of the shaft 3a of the winding frame 3 is mounted. Reference numeral 9 denotes a side edge of the base plate that comes down when the base plate 8 is raised so that both side plates and wheels 1 and 2 of the winding frame 3 are in contact with the ground, and casters 10 and 10 are attached to the side edges. be.

Effects of the invention The present invention has the above-mentioned structure, and after folding down the retractable side bearing bracket provided on the base plate and removing one side plate and wheel of the winding frame, and setting the wire rope on the winding frame, the wire rope can be attached. Attach the side plate/wheel to the winding frame with screws,
Since the shaft on that side is mounted with the folding side bearing bracket upright, the reel body can be easily inserted into the center hole of the coiled wire rope. It is simple and easy to set up.Also, raise the base plate so that the casters attached to the side edges of the base plate face down, place your hands on the base plate,
By pushing like a handcart, this rewinding machine can be moved by rolling with the wire rope set, using casters and side plates and wheels. Change of direction is also smooth by using casters, reducing work preparation time. I was able to shorten it to a large width. In addition, the above-mentioned conventional problems can be easily solved, as the unwinding operation can be carried out safely and quickly without twisting the wire rope.
