Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of trenchless drilling machines, in particular to a liquid-electric hybrid modular horizontal directional drilling machine. BACKGROUND

[0002] The main actions of horizontal directional drilling machine construction operation are rotation and push-pull. Generally, the rotation mechanism is the largest power consumption part of the drilling machine, and the working capacity (rated power) of the rotation mechanism is also the main factor determining the construction efficiency of the drilling machine.

[0003] At present, the rotation mechanism of the horizontal directional drilling machine at home and abroad is an integral part of the drilling machine, that is, once the drilling machine is completed, the rated power of the rotation mechanism cannot be changed. However, in engineering construction, due to different stratum conditions, the requirements for the capacity of the rotation mechanism are different. In soft soil layer, the rotation mechanism only needs smaller rotation power to achieve satisfactory construction efficiency; while in rock stratum or other hard stratum, the rotation mechanism needs greater power to meet better construction efficiency.

[0004] At present, the rotation capacity, push-pull capacity and total output power of the horizontal directional drilling machine at home and abroad are matched by each manufacturer according to their own understanding of the construction process during product design, which we call "integrated" drilling machine. Once the customer chooses to buy, he cannot change it himself. Therefore, the existing horizontal directional drilling machine has the following technical limitations:

[0005] Firstly, the stratum conditions encountered in horizontal directional drilling construction are changing, from silt to hard rock, with a large span. At present, there are only such "integrated" drilling machines on the market at home and abroad, which match the rotation, push-pull and total power at the design stage. When encountering strata that are not suitable for the performance indicators of the drilling machine, in order to achieve satisfactory construction efficiency, reduce construction cost and reduce construction risk, only by purchasing and replacing other drilling machines more suitable for the working condition can the above be achieved. In this way, it brings about repeated investment increase for the customer. At present, among the users of directional drilling machines, there is a large number of idle assets with multiple specifications and quantities of self-owned drilling equipment.

[0006] Secondly, in the case of large and super large horizontal directional drilling machines, the integrated drilling machine has a large weight, which exceeds the weight limit of conventional road transportation, has high transportation cost, and it is also difficult to enter and exit the construction site. How to disassemble and transport the integrated large drilling machine and conveniently assemble it on site is a problem that has not been solved.

[0007] Therefore, it is necessary to improve the existing technology to solve the above technical problems. SUMMARY

[0008] The application provides a liquid-electric hybrid module combined horizontal directional drilling machine, which solves the following problems: 1. Different construction needs are met through modular combination, and customer repetitive equipment investment is reduced; 2. The weight of a single drilling machine is reduced, the problem of overweight of a large drilling machine is solved, and the drilling machine is convenient to enter and exit a construction site; 3. In the engineering condition of available network electricity, the network electricity is used as a power source of a rotating mechanism module unit, fuel consumption is saved, construction cost is reduced, and tail gas emission of a diesel generator set is reduced.
