Problems solved by technology

When long rods with external keys such as drill pipes are changed from one diameter to another, the disassembly and assembly of this closed conventional support structure is time-consuming and laborious, and a set of supports must be remade, which increases the manufacturing cost. Conventional supports Devices do not allow for quick change and versatility of support devices
In addition, when long rods with external keys, such as drill pipes, are changed from one length to a longer length, the rod is not allowed to have deflection and sag deformation. In order to avoid the above-mentioned deflection and sag deformation, the support points are not required at both ends but Other parts, even the support points have to follow the pole, or the position of the support points can be adjusted, but this fixed closed support device in the prior art cannot solve such a problem
In addition, conventional support devices cannot accommodate long rods with external keys such as drill pipes with different numbers, sizes and forms of external keys.

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Figure 1a , 1b shows a front view and a side view of a support unit in the support device according to the present invention. As shown in the figure, each supporting unit includes a supporting structure supporting and driving the elongated rod 19, a driving device transmitting power to the supporting structure, and a base 2, wherein the supporting structure and the driving device are installed on the base 2. The base 2 is made into the form of a mobile trolley 2, which moves along the guide rail 1. Certainly the base 2 can also be made into other forms of mobile supports, and can also be directly moved on the ground.

[0022] The advantage of the base 2 being movable is that it can adapt to position changes and accompanying support, and it is easy to disassemble. Another advantage is that it can accommodate the support of ...

Abstract

The invention relates to a supporting device used for a slender bar, which is characterized by comprising at least one supporting unit, wherein each supporting unit comprises a supporting structure used for supporting the slender bar, a driving device transmitting power to the supporting structure and a base, the supporting structure and the driving device are both arranged on the base, and the base is movable. The invention can support bars with different lengths via the movement of the base and effectively reduces the pendulous deflection deformation of the bar.

Description

technical field [0001] The invention relates to a support device, in particular a support device for elongated rods. Background technique [0002] Drilling rods for piling mechanical rotary drilling rigs include friction rods with external three keys, three pairs of double keys, six keys, machine lock rods with oblique key pressure points, and combination rods of friction and machine locks. The diameter of the section bar generally has a variety of φ180, φ218, φ325, φ377, φ440, φ508, etc., the length is 10m-19m, and the slenderness ratio is much greater than 5, which is a typical slender rod. The support structure of conventional long rods with external keys such as drill pipes is such that one end of the rod is connected with the outer ring of the slewing support and the flange of the rod with bolts, and the inner ring of the slewing support is connected with the base with bolts. The base is Fixed, or one end of the rod is sleeved on the outside of the outer key of the rod...
