Abstract
The utility model relates to a hand wheel type rod-twisting device, which comprises an open-end wrench, a plurality of supporting rods are arranged on the outer side of the open-end wrench; an arc-shaped outer ring is connected to the two ends of the open-end wrench; and the supporting rods are respectively connected with the outer ring. The supporting rods are uniformly distributed on the outer side of the open-end wrench. The open-end wrench, the supporting rods and the outer ring are integrated into one body. The utility model not only can lower the work intensity of an operator and accelerate the assembling and the disassembling of a drill rod, but also shortens the assembling and disassembling time. In addition, the device has a simple structure and low cost.
Description
Technical field
The utility model relates to a kind of geological drilling mechanical fitting, particularly a kind of stubborn bar device of handwheel that is used to tighten drilling rod.
Background technology
During rig loading and unloading drilling rod, traditional approach is directly to hold drilling rod with hand, rotates drilling rod simultaneously and unclamps or tighten drilling rod.Because the long 50mm of screw thread between drilling rod and the drilling rod (or drilling rod catcher), pitch is about 4.5mm, therefore, unclamps at every turn or tightens drilling rod and need rotate about drilling rod (or drilling rod catcher) 10 circles.This mode of operation, the labour intensity of operator's hand is quite high, and operating environment is covered with mud, is prone to produce skidding, and after manually tightening, also needs to remove the pretension drilling rod length by length with open-end wrench, and operation is loaded down with trivial details, the operation effort.
Summary of the invention
The utility model technical problem to be solved is, and is not enough to prior art, provides a kind of and can alleviate operator's labour intensity, accelerates loading and unloading drilling rod speed, and the handwheel that reduces loading and unloading non-cutting times is twisted the bar device.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of handwheel is twisted the bar device, comprises an open-end wrench, and the outside of this open-end wrench is provided with many support bars; One circular arc outer ring is connected in the two ends of open-end wrench, and many support bars are connected with the outer ring respectively.
The utility model one preferred implementation is that these many support bars are evenly distributed in the outside of open-end wrench.
The another preferred implementation of the utility model is that this support bar is three.
The utility model preferred implementation again does, this open-end wrench, many support bars and outer ring are one-body molded.
Compared with prior art; The beneficial effect that the utility model had is: during the unloading drilling rod, do not need the operator to go unloading to be stained with the drilling rod of mud with hand at the very start, and handwheel capable of using is twisted the inertia unloading drilling rod of bar device; Realize the pretightning force between (or overcoming) drilling rod and the drilling rod (or drilling rod catcher); Not only the strength of the stubborn bar device of operator's hand has only about 1/8 of traditional unloading mode unloading drilling rod strength, has alleviated operator's labour intensity, and generally only need rotate stubborn bar device for two to three times and just can realize tightening and dismantling of drilling rod; Accelerate the speed of loading and unloading drilling rods, reduced loading and unloading non-cutting times.In addition, the utility model handwheel is twisted the bar device and is adopted circular contour, makes the unlikely handwheel that occurs of engineering site twist the situation appearance that the bar device is fallen into boring, has avoided the economic loss that causes thus.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model handwheel is twisted the bar device and is comprised an open-end wrench 1, and this open-end wrench 1 is identical with the spanner of existing open-end wrench.The outside of this open-end wrench 1 is provided with many support bars 2, and these many support bars 2 are evenly distributed in the outside of open-end wrench 1.In the present embodiment, be provided with three support bars 2, but the enforcement of the utility model is not limited to this, the number of this support bar 2 also can be 2,4,5 or more.One circular arc outer ring 3 is connected in the two ends of open-end wrench 1, and many support bars 2 also are connected with outer ring 3 respectively.This open-end wrench 1, many support bars 2 and outer ring 3 are one-body molded.
While actually employed; The operator twists the bar device with the utility model handwheel and is fastened on the drilling rod that needs to connect; Directly twist the outer ring 3 of bar device, and rotate handwheel and twist the unloading that the bar device is realized drilling rod, make the strength of operator's hand unloading have only about 1/8 of traditional unloading mode like this with holding the wheel of stopping in hand; And when utilizing the utility model unloading drilling rod; Do not need the operator to go unloading to be stained with the drilling rod of mud at the very start with hand; Operating environment more cleans, and utilizes handwheel to twist the inertia unloading drilling rod of bar device, realizes the pretightning force between (or overcoming) drilling rod and the drilling rod (or drilling rod catcher); The general rotation the utility model that only needs two to three times, the utility model just can be realized tightening and dismantling of drilling rod.Like this; Not only alleviated operator's labour intensity; Accelerated the speed of loading and unloading drilling rods, reduced loading and unloading non-cutting times, and the utility model handwheel is twisted the bar device and adopted circular contour; Make the unlikely handwheel that occurs of engineering site twist the situation appearance that the bar device is fallen into boring, avoided the economic loss that causes thus.
