Problems solved by technology

However, the longer the drill pipe, the greater the external force on the drill pipe in wind, vibration, and impact during work, and the longer the drill pipe itself, the worse its rigidity will be, which will not only seriously affect the verticality and other accuracy of construction , and it is likely to damage the drill pipe, and blindly developing equipment with larger specifications will increase the cost in terms of manufacturing, transportation, construction, etc., and is not conducive to energy conservation and environmental protection

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing. The description in this part is only exemplary and explanatory, and the present invention can be implemented in many different ways defined and covered by the claims, which should not have any limiting effect on the protection scope of the present invention.

[0024] A specific structure of the present invention is composed of a chassis 1, a fuselage 2, a drill mast 3, a goose head 4, a top bracket 5, a follower supporter 6, a drill pipe 7, a lifting device 8, a lower clamping guide mechanism 9, and a milling head 10. , winch system 11, power system 12, control system 13, etc., see attached figure 1 .

[0025] The lower part of the drill mast 3 is hingedly supported on the front of the fuselage 2, and the goose head 4 is located on the top of the drill mast 3 and is connected with the drill mast 3 by bolts through a circular flange. And the top bracket 5 is located at the t...

Abstract

A piling machine with a drill pipe following supporting function comprises a drill pipe, a drill mast and a hoist system, wherein the lower parts of the hoist system and the drill mast are mounted in the front of a machine body, a guide rail matched with the drill pipe in height is arranged on the front side of the drill mast, a following supporting device, a lifting device and a lower clamping guiding mechanism are mounted on the drill pipe from top to bottom sequentially, one clamping device which can clamp and loosen the drill pipe is mounted at the front end of each of the lifting device and the lower clamping guiding mechanism, and sliding sleeves are arranged at the other ends of the following supporting device, the lifting device and the lower clamping guiding mechanism and are glidingly connected to the guide rail. On the premise that the height of the drill mast is not changed, the drilling depth of the machine is substantially increased.

Description

technical field [0001] The invention relates to a pile-driving machine, in particular to a pile-driving machine with the function of following and supporting a drill rod. Background technique [0002] In the construction of various pile foundations, as the height of the building is getting higher and higher, and the safety requirements for the building are getting higher and higher, the construction depth of the pile foundation is also increasing. Due to the influence of its own size and height, the construction depth is difficult to meet the demand. The maximum drilling depth of the equipment is directly related to the length of the drill pipe, the longer the drill pipe, the deeper the drill. However, the longer the drill pipe, the greater the external force on the drill pipe in wind, vibration, and impact during work, and the longer the drill pipe itself, the worse its rigidity will be, which will not only seriously affect the verticality and other accuracy of constructio...
