Problems solved by technology

[0004] In the authorized announcement number CN203925283U, a non-excavation horizontal directional drilling rig is disclosed, which relates to the technical field of drilling rigs; It is equipped with a drill frame, a power station assembly, a hydraulic system and an electrical system. The drill frame includes a working slide rail. The drill pipe and the power head device are arranged on the work slide rail. The power head device includes a hydraulic motor, a reduction mechanism, and an operating valve. block, the hydraulic motor drives the deceleration mechanism to run, and at the same time drives the drill pipe to rotate, and the power head device moves forward and backward on the drill frame through the working slide rail; the hydraulic system, electrical system and power station assembly are all set in the drilling rig shell , the power station assembly includes a diesel engine, and the above-mentioned diesel tank is connected to the diesel engine through pipelines; its beneficial effect is that it does not need to dig the ground surface during construction, and pipelines can be laid to cross roads, railways, rivers, etc. The advantages of fast speed and high construction precision; however, the structure of the device is large and complex, and it needs to be transported by vehicles during transportation or transportation, which will cause great inconvenience

Embodiment 1

[0022] Such as Figure 1-3 Shown: a non-excavation type cross-road line laying device, including a traveling mechanism, an excavating mechanism arranged at the front end of the traveling mechanism, a pulling rope arranged at the rear of the traveling mechanism, arranged on the ground and The pulling mechanism matched with the pulling rope 15, the grouting mechanism arranged on the ground and matched with the excavation mechanism, and the control mechanism arranged on the ground and matched with the walking mechanism ;

[0023] Described walking mechanism comprises walking base 5, is arranged on the walking supporting column 14 of described walking base center, is arranged on described walking supporting column and the supporting telescopic link 12 of uniform distribution, is arranged on the described supporting telescopic link end Positioning legs 13, a plurality of walking telescopic rods 6 arranged on the side of the walking base, a walking motor 8 arranged at the ends of a...

Embodiment 2

[0030] The difference from the first embodiment is that the grouting hole communicates with the grouting pipe.

[0031] The grouting holes used in this embodiment are arranged on the surface of the excavation bit, which can soften the soil to be excavated during excavation, improve the efficiency of excavation, and reduce the difficulty of excavation.

Embodiment 3

[0033]It differs from Embodiment 2 in that: the traveling wheels use rubber wheels, and the outer surfaces of the traveling motor, traveling telescopic rod, supporting telescopic rod, excavating telescopic arm and excavating motor are provided with rubber sleeves for waterproofing. , to ensure the normal progress of the work, and at the same time, efficient heat dissipation can be achieved due to the soaked mud.

Abstract

The invention belongs to the technical field of line laying equipment, and particularly discloses a non-excavation type line laying device crossing a road. The device comprises a traveling mechanism,an excavation mechanism arranged at the front end of the traveling mechanism, a traction rope arranged at the rear portion of the traveling mechanism, a traction mechanism arranged on the ground and cooperated with the traction rope, a grouting mechanism arranged on the ground and cooperated with the excavation mechanism, and a control mechanism arranged on the ground and cooperated with the traveling mechanism. The non-excavation type line laying device crossing a road can rapidly form a channel under a rod, and can rapid achieve passing of a line in a traction mode after the excavation is finished so as to greatly simplify the structure of the excavation device.

Description

technical field [0001] The invention relates to the technical field of line laying equipment, in particular to a trenchless line laying device across roads. Background technique [0002] At present, with the expansion of urbanization scale, more and more lines go from the ground to the ground, but there are no underground passages reserved for some road surfaces, which makes it necessary to excavate again, but the existing construction devices are often relatively poorly equipped. Large, it needs to be transported by vehicles during transportation or transportation, which will cause great inconvenience, so a non-excavation type line laying device that can be replaced by small equipment is needed. [0003] In the authorized announcement number CN205100053U, a multi-group pavement pre-embedded protection pipeline is disclosed, including a pavement pre-buried groove, and a base layer is arranged in the pavement pre-buried groove, and its characteristics are: the base layer is p...
