Detailed Description

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

Integrated trench excavator

Fig. 1 is a schematic diagram showing the overall configuration of the integrated trench excavator of the present invention. As shown in fig. 1, the integrated trench excavator mainly comprises a main body 1, a traveling device 2, a power unit 3, a sawing device 4, a drilling and splitting device 5 and a breaking and grabbing device 6. Further, a control system not shown is also included.

In this specification, for convenience of explanation, a left-right direction on the paper surface of fig. 1 is referred to as a front-rear direction, a vertical direction on the paper surface of fig. 1 is referred to as a vertical direction, and a front-rear direction perpendicular to the paper surface of fig. 1 is referred to as a left-right direction.

As shown in fig. 1, the main body 1 is provided above the traveling device 2. The body 1 is provided with a power unit 2 for traveling drive and work drive. In fig. 1, it is schematically shown that the power unit 2 is provided at an upper portion of the body main body 1, and may be provided at any suitable position in the integrated trench excavator as long as the power unit 2 can perform a driving function. For example, the power unit for traveling drive may be a fuel engine, and the power unit for working drive may be driven by electric power.

The traveling device 2 arranged below the machine body drives the trench excavator to move forwards, backwards and rotate back under the driving of the power unit. As shown in fig. 1, although the crawler type traveling device is shown in the present embodiment, the present invention is not limited to this, and may be a wheel type.

A driver seat 8 on which a driver sits and operates is provided in front of the body main body 1.

A drilling and splitting device 5 taking hard rock as a main operation object and a breaking and grabbing device 6 taking small rock as a main operation object are arranged in front of the machine body main body 1; behind the machine body 1, a sawing device 4 for forming the boundary of the trench and a milling device 7 attached thereto for milling out the trench are provided.

Sawing device

As shown in fig. 1 to 4, the sawing means 4 of the sawing channel comprises sawing blades 42 (2 pieces in the present embodiment) arranged facing each other in a parallel manner, and a protective cover 41 at least partially covering the sawing blades 42. Fig. 1 shows a state where the protection cover 41 completely covers and stores the sawing blade 42; fig. 2 shows a state in which a part of the sawing blade 42 is exposed from the protective cover 41.

As shown in fig. 3A, 3B and 4, two sawing blades 42 are coaxially arranged in parallel with each other on opposite sides of a blade holder 44. The sawing blades 42 are for example circular and can be rotated under electric drive (e.g. a motor) around an axis passing through the centre of the two sawing blades 42.

The blade holder 44, on which the sawing blade 42 is arranged, is connected to a rail holder 46 (see fig. 5B), so that the sawing device 4 is arranged to the body of the machine body via the rail holder 46. The rail frame 46 can be extended and retracted in the forward and backward direction, whereby the sawing means 4 can be brought closer to or further away from the body in the forward and backward direction. By extension and retraction of the rail frame 46, a single sawing distance is completed. As an example, the single sawing distance is for example 4-6 m.

In addition, the sawing device 4 can also be traversed in the left-right direction relative to the fuselage body. As an example, the maximum distance of the lateral movement of the sawing device is, for example, 0.8 m. When the sawing operation is carried out on the boundary of the groove, for example, when the center of the groove is more than 1m away from the side wall, two crawler belts of the groove excavator can span two sides of the groove; when the distance between the center of the groove and the side wall is within 1m, the groove excavator can be stopped as close to the side wall as possible according to the condition of the side wall. The track direction is approximately consistent with the groove direction when the equipment is parked.

Fig. 3A and 3B show the lateral adjustment in a schematic view (the sawing device is shown with the hood removed for easy viewing of the sawing blade) in a position in which the sawing blade is substantially in the front-rear direction. The lateral adjustment travel of the sawing blade is from a substantially central position to near one end of the main body of the machine body. When the saw blade 42 is moved to the position shown in fig. 3A, the trench digging operation can be easily performed near the side wall if the trench digging machine is parked near the side wall. Fig. 3A shows a case where the groove is located near the left side wall (not shown), and if the groove is located near the right side wall in fig. 3A, the equipment can be operated in the reverse direction.

The sawing device 4 is provided at one end of the rail frame 46 so as to be rotatable via a pivot 45 (see fig. 5B), and is adjustable in position in the vertical direction with respect to the main body 1. Whereby the trench excavation depth can be easily set and adjusted.

Further, the sawing device 4 may be attached to one end portion of the rail frame 46 so as to be swingable in the left-right direction with respect to the rail frame 46 as shown in fig. 4. Thereby, the left and right deflection angle of the sawn groove can be adjusted. As an example, the left-right deflection angle range of the sawing device 4 may be in the range of 2 degrees to 30 degrees with respect to the front-rear direction.

Fig. 5A and 5B show the working state of the sawing device 4. When the equipment is in place, the sawing direction is approximately consistent with the direction of the groove, and the specific operation also needs accurate positioning. The accuracy of the trench-sawing boundary can be ensured, for example, by the trench excavator or in particular the sawing device being equipped with laser-guided instruments in the proceeding direction of trench excavation. The sawing device rapidly positions the sawing blade through two actions of transverse displacement and/or angle adjustment. In this embodiment, the maximum moving distance of the lateral movement of the sawing device is 0.8m, the left-right angle is adjusted to the range from 30 degrees on the left side to 30 degrees on the right side, and the single sawing distance after positioning is 4-6m for one cycle. The sawing operation is started by manually positioning the device and then pressing a key. The sawing device 4 firstly cuts down to a preset depth and then automatically saws forwards, and after reaching a single sawing distance, the sawing device 4 and the attached milling and excavating device 7 are recovered, for example, retreated to a position which does not interfere with other operations and walking of the walking device. Here, as an example, the milling and cutting device 7 is arranged coaxially with the sawing blade 42, and the milling and cutting device 7 is rotatable about the central axis of the sawing blade 42 while rotating relative to the ground to be milled.

In the operation process, the protection cover 41 that the saw cutting device has can be along with the operation degree of coverage of different and self-regulating to saw cutting blade 42 of degree of depth to ensure that operation device (saw cutting blade 42) does not expose, thereby can avoid mud splash, rubble piece to splash and hinder the people, but also can have the water spray dust fall, give sound insulation and fall the function of making an uproar. As shown in fig. 1 and 2, the protective cover 41 includes, for example, two substantially semi-cylindrical cover members that are pivotably connected at substantially the axial center. When the cover members are brought into a state where the opening portions face each other as shown in fig. 1, a cylindrical body can be formed, and the sawing blade 42 and the like are accommodated in the cylindrical body. When the cover members are rotated relatively around the coaxial shaft center, the cover members are in an open state in which a part of the cover members is overlapped and a part of the cover members is separated to form a fan-shaped opening, whereby the sawing blade 42 can be exposed. By adjusting the size of the open sector opening (with the lower edge of the protective cover closer to or further away from the lower edge of the saw blade), the degree of coverage of the saw blade 42 can be adjusted.
