Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a multifunctional overweight drill rod adding and subtracting device for a water well drilling rig. Background Art

[0002] The crawler-type multifunctional fully hydraulic water well drilling rig drilling technology has the advantages of fast relocation speed, high drilling efficiency, good hole-forming effect, and low comprehensive cost during construction. However, the drill rod equipped with this drilling rig is relatively thick and heavy. When installing the drill rod, the tool winch on the top of the drilling rig needs to be used to tie the drill rod with a lifting belt and then lift it. During the lifting process, the drill rod is easy to shake, which poses a safety hazard. This process not only takes a lot of time, but also requires multiple workers to operate. After the drill rod is installed, it is necessary to manually climb to the top of the frame to remove the lifting belt before drilling operations. In the process of reducing the drill rod, it is necessary to manually tie and remove the lifting belt back and forth. This process still requires climbing to the top of the frame. After the lifting belt is tied, there is still a risk of slipping and falling off in the process of dragging the drill rod out. The traditional operation of adding and reducing drill rods is time-consuming and labor-intensive, and the lifting belt has poor stability, which makes it easy for the drill rod to slide or fall. During the whole process, personnel climbed to the top of the frame many times, which poses a safety hazard. Utility Model Content

[0004] The technical solution of this utility model is as follows:

[0005] A multifunctional water well drilling rig overweight drill rod adding and subtracting device comprises a sliding card and a fixed card, a steel wire rope is connected between the sliding card and the fixed card, and the drill rod adding and subtracting device (the above-mentioned multifunctional water well drilling rig overweight drill rod adding and subtracting device) can be used in conjunction with a winch on the drilling rig to complete the drill rod adding and subtracting operation.

[0006] As the core technical concept of the utility model, the fixing card is configured to be fixedly matched with the end of the drill rod. Specifically, a groove is provided on one side of the fixing card, and a second locking pin is movably provided at the opening of the groove, which can fix the drill rod in the groove and increase the stability of the drill rod; the sliding card is configured to be able to open or close freely, and can be slidably mounted on the outer ring of the drill rod in the closed state. Specifically, the sliding card includes two arc plates with a semicircular cross-section, one side of the two arc plates is hingedly connected, and the other side is movably provided with a first locking pin to ensure that the sliding card can slide stably on the drill rod.

[0007] On the basis of the above structure, when installing the drill rod, it is only necessary to fix the groove of the fixing card and one end of the drill rod, and set the sliding sleeve on the outer ring of the drill rod. Then, the sliding card is connected through the tool winch of the drilling rig and tightened. After the wire rope between the fixing card and the sliding card is tightened, the drill rod rises and starts to be installed. After the installation is completed, the wire rope is loosened, and the sliding card slides down to the bottom of the drill rod. At this time, it is only necessary to disassemble the sliding card and the fixing card at a low place, eliminating the need for personnel to climb to the top of the frame.

[0008] When reducing the drill rod, first install the fixed card and the sliding card on the drill rod at a low position, then use the tool winch to connect the sliding card, tighten the wire rope, and then you can carry out the drill lifting and reducing work. It is not only simple to operate, but also avoids the safety hazard of climbing to the top of the frame.

[0009] Furthermore, one side of the sliding card and the fixed card is provided with an annular component, which is convenient for connecting with both ends of the wire rope. There are two annular components on the sliding card, one is connected to the fixed card through the wire rope, and the other is connected to the wire rope on the tool winch on the top of the drilling rig.

[0010] As a preferred embodiment, the first locking pin on the sliding card and the second locking pin on the fixed card are respectively provided with a first anti-slip component and a second anti-slip component to prevent the locking pin from being accidentally opened, causing the drill rod to slip and fall off.

[0011] Furthermore, the two ends of the wire rope are respectively passed through the annular components of the fixing card and the sliding card, and then the ends of the wire rope are fixed by a U-shaped clamp lock buckle, which facilitates the installation and removal of the wire rope while preventing it from loosening.

[0012] As a preferred embodiment, the diameter of the annular components on the fixed card and the sliding card is 10-35 mm, and this range can be matched with steel wire ropes of various specifications to ensure that the steel wire ropes can pass through the annular components and be fixed.

[0013] Preferably, the length of the wire rope connecting the fixed card and the sliding card is 2-3 meters. If the wire rope is too short, the stability of the drill rod during movement will be reduced. If the wire rope is too long, the power consumed by the tool winch to lift the drill rod will be increased.

[0014] Through the above design, the beneficial effects of the utility model are:

[0015] During the construction process, personnel only need to install the device on the drill rod at a low position and cooperate with the winch on the drilling rig to complete the operation of adding or removing the drill rod, avoiding the safety hazard of personnel climbing the frame multiple times, improving the stability of the drill rod during operation, and effectively preventing the drill rod from slipping and falling off. It is safe, reliable, and saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS
