Abstract

PURPOSE:To enable saving of labor, by a method wherein sensors are located at opposite ends of a ditch in which a gas pipe is planned to be buried, detecting means are positioned in front and in the rear of an embedding equipment, and a forward and backward clutch is automatically switched if the detector detects that the embedding equipment approaches one end of the ditch. CONSTITUTION:A vehicle 2, which is positioned across a ditch 13 and reciprocates over the ditch 13 where a gas pipe is planned to be curied, discharges soil and sand, loaded in a tank 3, into the ditch when it travels forward, and consolidates the discharges soil and sand by a rammer 4 when it runs backward. Detecting means 15 are attached to the vehicle 2, sensors 14 and 14' are installed at opposite ends of a range, at which the vehicle reciprocates over the ditch 13, the sensor 14 detects that the vehicle 2 approaches if the vehicle 2 approaches the one end of the ditch 13 as the vehicle 2 discharges soil and sand in the ditch 13, and forward and backward electromagnetic clutches 21, 22 are switched to a backward movement side. Then, the vehicle 2 starts to perform operations to consolidate soil and sand by means of a rammer 4.

Description

[Detailed Description of the Invention] This invention aims to improve work efficiency and save labor in gas management equipment that effectively discharges earth and sand into trenches dug for burying gas pipes, etc. underground. This relates to an automatic go-around device.

The present inventor has provided the gas management equipment as described above, and the present invention further provides an automatic go-around device for improving the functionality of the gas management equipment.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

1 and 2 are partially sectional side views of the gas management equipment according to the present invention, and FIG. 3 is a sectional view taken along line X-7 in FIG. 1.

The earth and sand filling machine is equipped with an operating engine section 2 on the upper curved blade of the chassis 1, a tank 3 for loading soil at the rear, and a rammer 4 between the two, and a running section 5 such as a crawler below the chassis 1. It is something that buds.

The operation engine section 2 has an engine and various parts! A screw 7 is provided inside the tank 3 facing the discharge port 6, and a root wheel 8 for dispersing soil is installed slightly above the tank 3.
．． 8' is also provided. Note that the discharge port 6 may be opened and closed by an appropriate amount 9.

The rammer 4 has a rod 11 descending from the main body 1O, and a hammer 12 is attached to the lower end of the rod 11, and the hammer 12 itself is designed to vibrate up and down.

With this configuration, the go-around work is performed over a fixed distance along the trench 13 dug under the ground.

That is, during the forward movement (Fig. 1), the cover 9 of the discharge port 6 is opened, and the screw 7, impeller 8, 8, etc. are also rotating.
Earth and sand are discharged from the discharge port 6 into the groove 13. After traveling a certain distance, the rammer 4 then goes back, but at this time (FIG. 2) the main body 10 of the rammer 4 lowers and the rammer 12 also vibrates up and down, compacting the discharged earth and sand. This back-and-forth movement and the associated work are repeated several times to complete the work in the section (there are cases where the work is completed in a back-and-forth movement).

By the way, in order to save labor, this gas management equipment is equipped with an automatic go-around device.

Figure 4 is an explanatory diagram of this automatic go-around device.First, a sensor 14.14 such as a navigation device is placed on the ground in order to set the range (usually about 15 m) for reciprocating. On the other hand, the gas management equipment is also provided with a pair of detection tools x5, xj that contact this sensor 14.14 for rotational displacement, and also connect both detection tools 15.15 with a tie rod 16, A detection piece 17 is installed in advance.

FIG. 4 shows the state just before the end of the forward movement, but if the forward movement continues, the detection tool 15 will come into contact with the sensor 14, and due to the reaction force will be rotated as shown by the dashed line. At this time, due to the presence of the tie rod 16, the other detection tools 15 are similarly displaced, and the detection piece 17 is also displaced to the position indicated by the chain line, and the switch 1
8 to switch 19. This electrical fluctuation is switched from the forward rotation electromagnetic clutch 21 to the reverse rotation electromagnetic clutch 22 via the converter 20, and the aircraft shifts from forward to go-around. Also, when the vehicle shifts from going back to going out, the detection device 15 senses the presence of the sensor 14'. Note that these conversion operations can be performed manually by operating the switching lever 23 linked to the tie rod 16, and of course a stopping operation that does not perform either forward or backward movement is also possible.

The configuration of the thin tube 4 shown in FIG.
．． 15 may be applied directly to the forward/reverse switching lever.

Next, groove 3 to be filled with earth and sand is almost straight, and the interval for reciprocating is relatively short, about 15 m, so there is no need for a special automatic steering device, but depending on the situation, the groove Even if the number 13 is facing up, an automatic steering device that imitates that face may be installed.

An example of this is shown in Figures 5 and 6, which are equipped with guide rollers 24 that fit tightly into the grooves 13 at the front, rear, or both of the aircraft, thereby forcibly steering the aircraft. It may be.

On the other hand, FIG. 7 shows another example, in which the guide rollers are made of two divided molds 25 and stones, each of which is pressed against the side wall of the groove 13 by a spring 27, etc., and the left and right guide rollers are moved by changing the lateral pressure. 25. A should be able to move independently in the axial direction. A switch group 29 is installed to catch the axial movement of these left and right guide rollers; .

As a result, the traveling multi-latch 31.
32 is disconnected, and on the other hand, the running latch 3L32 on the side where the lateral pressure is increased is kept connected to follow the bending of the groove 13.

As described above, the present invention is a self-propelled vehicle that travels back and forth a certain distance along a gas management groove 13, and discharges the earth and sand loaded in the tank 3 into the groove 13 during the go-around. In a gas management equipment that compacts released earth and sand with a rammer 4, two sensors 1 are used to set the reciprocating range.
If the 4.14 is installed on the ground, as the aircraft moves back and forth,
An automatic go-around device is provided which detects the approach of each sensor 14, 14 and switches the forward and backward clutches as appropriate.

Therefore, since no human is required for the reciprocating operation, labor is saved, work is stabilized, and efficiency is increased.

Furthermore, since the degree to which people touch the aircraft body may be small, dangers can be prevented and safety can be ensured.

In addition, various excellent effects can be expected, such as a simple structure, no interference with manual operation, and no interference with the versatility of the machine.

[Claims] A self-propelled vehicle that travels a certain distance back and forth along a gas management trench, and when going back and forth, it releases the earth and sand loaded in the tank into the trench, and when going back, it hits the released earth and sand with a rammer. For gas management equipment, if two sensors are installed on the ground to set the range of reciprocation, as the aircraft makes a reciprocation, the approach of each sensor will be detected and the forward/reverse clutch will be switched accordingly.
