Detailed Description
In order to make the technical means, technical features, objects and technical effects of the present utility model easy to understand, the present utility model will be further described with reference to the specific drawings. It will be apparent that the described embodiments are merely some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
Example 1
1-3, A novel catwalk drilling tool righting device comprises a righting arm 1, wherein the righting arm 1 is hinged with a gear lever arm 3 and a second swinging shaft 8, the gear lever arm 3 is hinged with a first hydraulic cylinder 2, and the first hydraulic cylinder 2 is hinged with the righting arm 1; the first hydraulic cylinder 2 swings through the telescopic driving lever arm 3.
The first hydraulic cylinder 2, the gear lever arm 3 and the righting arm 1 are always positioned in the same plane, so that the device can clamp drilling tools with different diameters, stability in clamping is improved, the drilling tools are prevented from falling, and potential safety hazards are reduced.
The gear lever arm 3 one side articulates there is first oscillating axle 5, first oscillating axle 5 articulates with second pneumatic cylinder 4, second pneumatic cylinder 4 articulates with righting arm 1, first oscillating axle 5 is connected with first gear lever 6, second pneumatic cylinder 4 swings through flexible drive first oscillating axle 5, first gear lever 6, one side of second oscillating axle 8 is fixed with righting wheel 9, second oscillating axle 8 opposite side articulates with third pneumatic cylinder 7, third pneumatic cylinder 7 swings through flexible drive second oscillating axle 8, righting wheel 9, third pneumatic cylinder 7 articulates with righting arm 1.
A second gear lever 10 is connected to one side of the righting wheel 9.
Working principle: when a drilling tool is put on, a conveying arm (not shown in the drawing) drives a centralizing arm 1 to retract to a minimum position, then a first hydraulic cylinder 2 retracts to enable the angle between a gear lever arm 3 and the centralizing arm 1 to be maximum, and a second hydraulic cylinder 4 retracts to enable a first gear lever 6 to rotate through a first swinging shaft 5, so that the first gear lever 6 and the gear lever arm 3 are in a parallel state; the third hydraulic cylinder 7 also retracts, so that the second swinging shaft 8 drives the righting wheel 9 to be parallel to the righting arm 1, and the drilling tool is connected with a traveling crane system (not shown in the figure). The hanging elevator hung below the drilling machine floating system descends to lock the front end joint of the drilling machine and then ascends along with the floating system to drive the drilling machine to move upwards, and when the drilling machine moves to a proper position, the second hydraulic cylinder 4 stretches out to enable the first baffle rod 6 and the baffle rod arm 3 to be in a vertical state; the third hydraulic cylinder 7 also stretches out, so that the second swinging shaft 8 drives the righting wheel 9 to be in a vertical state with the righting arm 1, the drilling tool is contacted with the righting wheel 9 at the moment, then the first hydraulic cylinder 2 stretches out, the first gear lever 6 is pressed onto the drilling tool, the drilling tool is fixed and does not shake at the moment, and further under the protection of the second gear lever 10, the drilling tool can not turn over and fall.
