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 in particular, it is capable of smoothly lowering a hydraulic grab equipped with a rider to an earth and sand mining site. This invention relates to a guide device for a device for transporting earth and sand, etc.

[Conventional technology] Generally, at construction sites for high-rise buildings, etc., when the building is several floors underground, the earth and sand are initially removed using bulldozers, etc., but as the excavation gradually progresses, angle It is a type of tunnel that is dug like a vertical shaft. A grab bucket is used to dig this shaft, and most use hydraulic grabs. A carrying out device using this 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 composed of a cube-shaped angle, and four carrier rollers 3A, 3B, 3C, and 3D are provided at the top of this cube-shaped angle.
The carrier rollers 3A, 3B and the carrier rollers 3C, 3D are placed on the rails of the horizontal frame 1A, respectively, 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 5, 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 loosen the wire 5. Then, the wire 5 gradually becomes slack, and the hydraulic grab 6 gradually goes down, moving down inside 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.
Collect sediment, etc. The earth and sand collected by the hydraulic grab 6 is raised again by the winch 2 and transported outside, traversed by the traverse device 3, and loaded onto a transport vehicle or the like.

[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 a single wire and no guide is provided, hydraulic grabs are installed in the angled pit made of H steel vertically and horizontally. When unloading, the hydraulic grab rotates and collides with the H steel, making it impossible to unload smoothly. Furthermore, in the case of conventional equipment,
When lifting a hydraulic grab to discharge collected earth and sand, it collides with the H-steel and cannot be raised smoothly, and each time it collides, several workers must immediately lift it, which is extremely inefficient. Ta. In addition, conventionally, there is a 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. Generally used.

In order to prevent deterioration in workability due to torsion that has conventionally occurred in the conventional device shown in FIG. 1, the inventor of the present invention has already devised the provision of a rider on the hydraulic grab. However, even if the rider is equipped, several workers must perform the fitting work to fit it into the rail of the guide channel formed in the U-shaped rail and guide the hydraulic grab. However, it has the disadvantage that it cannot be fitted smoothly. In addition, when a hydraulic grab moves sideways and stops, the hydraulic grab swings due to inertia, so it is necessary to catch this movement.The hydraulic grab alone weighs between 1 ton and several tons, making it difficult to catch it with a guide channel. However, it has the disadvantage that it is difficult to install a guiding device such as a guide channel.

[Purpose of the invention] The purpose of the invention is to provide a guiding device for a device for discharging earth and sand, etc., which can receive a rider and smoothly raise and lower a hydraulic grab without requiring the hands of a worker.

Since it is configured like this,
Now, while keeping the hydraulic grab 21 in contact with the rider 20, the traversing device 15 is moved to the rider introduction section 25 by a drive device (not shown). The rider 20 moved by the traverse device 15 collides with the pipe 105 of the rider introduction section 25 and its momentum is relaxed, and the vertical rider rollers 88 and 91 of the rider 20 come into contact with the introduction plate 106. When the rider 20 is thus fitted into the rider introduction section 25 as shown in FIG. 7, the winch 14 is driven to loosen the wires 18 and 19. Then, hydraulic grab 2
Both the rider 1 and the rider 20 gradually move down the surface of the introduction plate 106 while rotating the rider vertical rollers 88 and 91. As the rider 20 gradually descends, the vertical rollers for the rider are guided by the channel guide 26 by the guide side plates 107 and the guide plate 108, and the rider descends as shown in FIG.
When the rider 20 reaches the stopper 27 and continues to drive the winch 14 to loosen the wires 18 and 19, the rider 20 cannot go lower due to the stopper 27, so the hydraulic grab 21 gradually lowers. By driving the hydraulic grab 21 as shown in FIG.
Collect 00. Sediment 5 by hydraulic grab 21
After collecting 00, 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
It starts to rise when it reaches 0. When the rider 20 and the hydraulic grab 21 rise together and reach the rider introduction part 25, the drive of the winch 14 is stopped and the traversing device 15 is moved by the drive device, and the hydraulic grab 2
1 reaches the top of the hopper 24 and stops, and the hydraulic grab 21 is operated to throw 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 lowered from the rider 20 to the soil sampling site, it is suspended by four wires.

[Effect of idea]

As explained above, according to the present invention, since the pipe is used as a member for absorbing the impact when a rider collides with the rider, the impact can be sufficiently mitigated and received.

Further, according to this embodiment, when introducing the rider, the introduction member is provided with a spherical opening on the side into which the rider enters, so even if there is some deviation, the rider can be introduced smoothly.

Furthermore, according to the present invention, since the guide side plate and the guide plate are provided with a tapered slope toward the guide channel, it is possible to smoothly guide the guide channel to the guide channel without requiring the operator's hands. can.

As described above, according to the present invention, the rider can be received and the hydraulic grab can be smoothly raised and lowered without requiring the hands of a worker.
