Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1-4, a counterweight device of a rotary drilling rig comprises a support 1, wherein column holes in a circular array are arranged on the support 1, a lead column 2 is arranged on the column hole, four side lugs 3 are equidistantly arranged on the side surface of the support 1, the side ears 3 are provided with rotary locking pieces 4 through bolts, a corresponding clamping piece 6 is arranged between the two opposite rotary locking pieces 4, a plurality of handle grooves are arranged in the middle of the rotary locking piece 4, an arc-shaped connecting piece 7 is welded at the other end of the rotary locking piece 4, the adjacent connecting pieces 7 are mutually meshed, a fixed base 8 is matched below the support 1, the fixed base 8 is welded on the rotary drilling rig, three fixing plates 9 which are equidistantly spaced are arranged on the fixing base 8, and an equilateral triangle is formed between the fixing plates 9. The handle 5 is welded at the top end of the lead column 2. The upper surfaces of the side ears 3 and the upper surface of the support 1 are positioned on the same horizontal plane. Rotatory retaining member 4 is the rectangle structure, 4 totally, every the radian of the connecting piece 7 on the rotatory retaining member 4 is the quarter circle. The connecting piece 7 and the clamping piece 6 are both installed on the rotary locking piece 4 through screws and can be detached. The height of the fixing plate 9 is half of that of the support 1, and the support 1 is provided with a groove matched with the fixing plate 9.

The fixed base 8 is welded at the tail part close to the rotary drilling rig, and the fixed base can be welded or fixed by screws. After the fixing base 8 is fixed, the support 1 is sleeved in and fixed with the fixing plate 9. The support 1 is made of lead materials, and an iron sheet is wrapped outside the support. And generally, the lead column 2 is placed in a storage box in the middle of the rotary drilling rig. When the front end part of the rotary drilling rig needs to be inclined forwards and the counterweight device needs to balance the gravity center, the lead column 2 can be added into the support 1. After the lead column 2 is added, different clamping pieces 6 or connecting pieces 7 are selected according to the position and the symmetrical relation of the added lead column 2. If the lead posts 2 are symmetrically arranged on two sides, the clamping piece 6 is selected. The connecting piece 7 is used if the lead posts 2 are installed adjacently. The clamping piece 6 or the connecting piece 7 is mainly used for preventing the lead column 2 from falling out due to vibration and the like during work.

In most cases, in order to reduce the replacement of the clamping piece 6 or the connecting piece 7 back and forth, because there are four rotary locking pieces 4, two adjacent rotary locking pieces 4 can be selected to be respectively the clamping piece 6 and the connecting piece 7, and the other two rotary locking pieces can be replaced according to the requirement. Each lead column 2 weighs about 40kg-70kg, and can be matched and selected according to requirements. The gravity center position required by the rotary drilling rig before working can be effectively changed.

The foregoing description is only exemplary of the preferred embodiments of the application and is provided for the purpose of illustrating the general principles of the technology and the like. Meanwhile, the scope of the invention according to the present application is not limited to the technical solutions in which the above-described technical features are combined in a specific manner, and also covers other technical solutions in which the above-described technical features or their equivalent are combined arbitrarily without departing from the inventive concept described above. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
