Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Fig. 1 is a schematic structural diagram of a drill rod clamping device provided by the present invention. Referring to fig. 1, the drill rod clamping device includes: the device comprises a support column 1, a connecting rod 2 and a clamping plate 3; the number of the support columns 1, the number of the connecting rods 2 and the number of the clamping plates 3 are two, the two connecting rods 2 are connected between the two support columns 1, each connecting rod 2 is movably connected with one clamping plate 3, and one side, contacted with the two clamping plates 3, of each connecting rod is provided with a groove 4; the drill rod clamping device is placed at the wellhead, the two clamping plates 3 are combined, and the drill rod is clamped between the two grooves 4.

It should be noted that, after the drill rod clamping device is placed at a wellhead, the two clamping plates 3 are opened, a drill rod is placed in the clamping devices, and the two clamping plates 3 are combined, so that the drill rod is positioned between the two grooves 4, the drill rod is fixed without being clamped by pipe tongs by workers, and the drill rod clamping device is firm and free of potential safety hazards.

Furthermore, a first handle 5 is arranged on one of the clamping plates 3, and a second handle 6 is arranged on the other clamping plate 3. So that the two clamping plates 3 can be opened and closed by the first handle 5 and the second handle 6, and the use is more labor-saving.

Further, a hoisting ring 7 is arranged on the drill rod clamping device.

Further, a hauling rope 8 is arranged on the hoisting ring 7. Therefore, the drill rod clamping device can be dragged by the traction rope 8 on the lifting ring 7, so that the use is more labor-saving.

Further, the shape of the groove 4 is semicircular. Thereby the drill rod can be more matched. In addition, the size of the combined grooves 4 can be slightly smaller than that of the drill rod, so that the grooves 4 can clamp the drill rod.

Furthermore, the first handle 5 is shorter than the second handle 6, and the end of the first handle 5 away from the splint 3 is provided with a first fixing rod 9 and a second fixing rod 10 from top to bottom, the first fixing rod 9 is movably connected with a first connecting plate 11, the second fixing rod 10 is movably connected with a second connecting plate 12, the end of the first connecting plate 11 away from the first fixing rod 9 is connected with a first clamping plate 13, the end of the second connecting plate 12 away from the second fixing rod 10 is connected with a second clamping plate 14, the end of the first clamping plate 13 away from the first connecting plate 11 is connected with a first fixing plate 15, the end of the second clamping plate 14 away from the second connecting plate 12 is connected with a second fixing plate 16, both the first fixing plate 15 and the second fixing plate 16 are provided with connecting holes, the first clamping plate 13 is rotated to the upper side of the second handle 6, the second clamping plate 14 is rotated to the lower side of the second handle 6, bolts 17 pass through the two attachment holes to secure the first and
