Embodiment Construction

[0029] In order to make the technical solutions and advantages in the present application, the exemplary embodiments of the present application will be described in detail below with reference to the accompanying drawings, which is apparent that the described embodiments are only part of the embodiments of the present application. Not the exhaustion of all embodiments. It should be noted that the features in the embodiments and embodiments in the present application may be combined with each other in the case of an unable conflict.

[0030] Verticalness is an important parameter measuring the quality of pile. If the pile is tilted more than a certain angle, it will cause the pile carrying capacity to be reduced, and it cannot be used, thereby causing economic losses, and will affect the construction progress and the quality of the project. The verticality of the sleeve determines the verticality of the pile of concrete insertion.

[0031] In the relevant technique, the detection o...

Abstract

The embodiment of the present application provides a full-casing full-rotation drilling rig equipment, including: a main frame with a vertical support column, a horizontal support column, a first sensor and an adjustment member; the first sensor and the adjustment member are arranged at the lower end of the vertical support column The rotary drilling device is connected to the horizontal support column and is used to drive the casing to perform rotary motion; the deviation correction rod is connected to the vertical support column and has a telescopic rod, a second sensor and a contact end, and the contact end is used for contact with the casing. The outer cylindrical surface is in contact, and the second sensor is arranged between the contact end and the telescopic rod; the controller is used to determine the tilt of the main frame according to the detection result of the first sensor, and to control the adjustment member to adjust the corresponding vertical support rod, and also use the When the inclination of the casing is determined according to the detection result of the second sensor, the telescopic rod is controlled to adjust the casing until the verticality of the casing meets a preset requirement. The application realizes automatic deviation correction of the equipment itself and the casing, and has high flexibility and high reuse rate.

Description

Technical field [0001] The present application relates to engineering machinery technology, in particular, involving a full set of rolled rotary rig equipment. Background technique [0002] As the urban construction process is accelerating, the road network is constantly improved, how to carry out the construction, foundation reinforcement treatment and construction of the net air space under infrastructure, such as high-speed rail, municipal, bridge, etc., and cannot affect the safety of infrastructure. Stable operation is a difficult problem for long-term troubles. [0003] In scenarios such as enriched structures, a full-length rotary rig is usually required to be piled. The full set of ride rigs generally refers to the apparatus for applying torque and vertical load using a full rotary rig, so that the sleeve is rotatably pressed while rotating while the sleeve is rotated. Such as figure 1 As shown, the structure of the existing full set of tubular full rotary rig includes a ...
