Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a device for transporting earth and sand using a grab bucket, especially a hydraulic grab, and particularly for smoothly transporting earth and sand collected by the hydraulic grab to the outside. This article relates to a device for transporting earth and sand, etc.

[Conventional technology]

Generally, at the construction site of a high-rise building, if the building is several stories underground, the earth and sand are initially removed using bulldozers, etc., but as the digging progresses, an angle is formed with H steel and a vertical shaft is opened. It is something that is dug like digging. A grab bucket is used to dig this shaft, and many hydraulic grabs are used. This carrying out device using a hydraulic grab has a configuration as shown in FIG. That is, the winch 2 is provided on the upper part of the angle 1 horizontal frame 1A, and the lower part of this horizontal frame 1A is formed in the shape of a rail, and the traversing device is mounted on the horizontal frame 1A formed in the rail shape. 3 is provided. This traversing device 3 is constituted by a cube-shaped angle, and four carrier rollers 3A, 3B, 3C, and 3D are provided at the top of this cube-shaped angle. 3B and carrier roller 3
C and 3D are placed on the rails of the horizontal frame 1A, and are configured to move in the direction shown by arrow A on the rails of the horizontal frame 1A. Furthermore, two carrier sheaves 3E and 3F are rotatably provided at the lower part of the angle of the traversing device 3.

In addition, an end sheave 4A is attached to one end of the horizontal frame 1A,
4B is provided. This end sheave 4A,
A wire 5 wound around the winch 2 is suspended from 4B, and this wire 5 is suspended from the carrier sheave 3E of the traversing device 3. The wire 5 suspended from the carrier sheave 3E is suspended from the sheave 6A of the hydraulic grab 6, and is suspended from the carrier sheave 3F of the traverse device 3. The wire 5 suspended from the carrier sheave 3F of the traverse device 3 is fixed to the vertical frame 1B of the angle 1 by an appropriate method.

In the conventional unloading device configured as described above, first, the traversing device 3 is traversed by a drive device (not shown), and the hydraulic grab 6 is moved to an appropriate location. When the wire 5 reaches a predetermined location, the winch 2 is operated to round the wire 5. Then, the wire 5 gradually becomes slack, and the hydraulic grab 6 gradually goes down, moving down within the angle formed by the H steel 7. The hydraulic grab 6 is then lowered to the site where the earth and sand 8 is located, and there, the hydraulic grab 6 is operated by a worker to collect the earth and sand. The earth and sand collected by the hydraulic grab 6 is raised again by the winch 2 and discharged to the outside, traversed by the thrusting and traversing device 3, and loaded onto a carry-out vehicle or the like.

[The problem that the invention attempts to solve]

However, in the case of such conventional earth and sand transport equipment, even if the traversing device stops,
The hydraulic grab swings due to inertia, and several workers have to hold it down, stop the swing, and then operate the winch to lower the hydraulic grab, which is extremely time-consuming and reduces work efficiency. It had In addition, in the case of such conventional equipment, since it is lowered by one or two wires and no guide is provided, it can be lowered into the underground mine with angles assembled vertically and horizontally using H steel. When lowering the hydraulic grab, the hydraulic grab rotates and hits the H steel, making it impossible to lower it smoothly. Furthermore, with conventional equipment, when lifting the hydraulic grab to carry out the collected soil, it collides with the H steel and cannot be raised smoothly, and each time it collides, several workers must immediately lift it. It was extremely inefficient. In addition, there is a conventional hydraulic grab with a guide that lowers the hydraulic grab along a guide, but this is not equipped with a traversing device and has extremely poor workability.Currently, a device as shown in Figure 1 is generally used. It is used.

It has not been possible to attach a guide to the conventional device shown in FIG. 1 because it is difficult to smoothly fix the hydraulic glove to the guide.

[Purpose of invention]

The purpose of this invention is to allow the hydraulic grab to be raised and lowered smoothly without colliding with the frame built in the soil, and to move the hydraulic grab to the transport vehicle for earth and sand. The goal is to provide equipment.

[Means for solving problems]

The present invention is an earth and sand transport device that collects earth and sand from a mine using a hydraulic grab, then lifts it to the ground using a winch or the like and loads the collected earth and sand onto a transport vehicle, etc., in which the hydraulic grab is guided. a guide device, a shock absorbing member for mitigating the impact when the guide device is introduced, an introduction member for introducing the guide device so as to fit between the pair of guide devices, and a shock absorbing member connected to the introduction member. A lidar introduction part configured with a guide member for guiding the hydraulic grab to the earth and sand extraction site, and a guide channel that guides the hydraulic grab up and down to the earth and sand extraction site after the introduction of the guide device. The device is characterized in that it includes a pair of left and right guiding devices.

Both the rider 20 and the rider 20 gradually descend on the surface of the introduction plate 106 while rotating the rider vertical rollers 88 and 91. As the rider 20 gradually descends, the rider vertical rollers are guided by the channel guide 26 by the guiding side plates 107 and the guide plate 108, and the rider 20 descends as shown in FIG. When the rider 20 reaches the stopper 27 and continues to drive the winch 14 and loosen the wires 18 and 19, the rider 20 cannot go any further down due to the stopper 27, so the hydraulic grab 21 gradually lowers. By driving the hydraulic grab 21 as shown in FIG.
Collect 0. Sediment 50 by hydraulic grab 21
After collecting 0, drive the winch 14 to wind up the wires 18 and 19, and the hydraulic grab 2 starts.
Rider 1 is gradually pulled up and Rider 2 stops at the stopper 27 of the guide channel 26.
When it comes into contact with the rider 2, this hydraulic grab 21

5, the drive of the winch 14 is stopped and the traversing device 15 is moved by the drive device, and the hydraulic grab 21 is moved.
Traverse until it reaches the top of the hopper 24 and stop,
The hydraulic grab 21 is operated to put the collected earth and sand into the hopper 24. The earth and sand put into the hopper 24 are carried outside by a transport vehicle (not shown) provided below the hopper 24. As is clear from FIG. 4, when the hydraulic grab 21 is moved away by the rider 20 and lowered to the earth and sand sampling site, it is suspended by four wires.

[Effect of idea]

As explained above, according to the present invention, the rider 20 is provided on the upper part of the hydraulic grab 21, and the rider 20 is fitted into the rider introduction part, so that it can be smoothly guided into the guide channel.

In addition, according to the present invention, unlike the conventional method in which the hydraulic grab is lowered without guidance, the rider is always
The hydraulic grab can be lowered smoothly to the extraction site without colliding with the H steel used in the framework of the shaft because it moves up and down in a constant motion.

Furthermore, according to the present invention, since the four wires are maintained at a constant interval by the vertical and horizontal rollers of the rider, the hydraulic grab can be lowered from the rider to the sand mining site from the stopper position of the guide channel. In some cases, the hydraulic grab does not rotate as in the conventional case.

Furthermore, according to the present invention, since the rider is provided and moves up and down along the guide channel, no vibration occurs.

Furthermore, according to the present invention, since the rider is raised and lowered along the guide channel, even if the shaft becomes deeper, it is possible to lower the rider further by simply adding a guide channel.

In this manner, according to the present invention, the hydraulic grab can be smoothly raised and lowered without colliding with the frame set in the ground.
