Abstract
The utility model discloses a falling prevention follow-up frame sliding lug for a rotary drilling rig. The falling prevention follow-up frame sliding lug comprises a sliding lug vertical plate, a sliding lug reinforcing plate is welded to the edge of the outer side of the sliding lug vertical plate, a falling prevention reinforcing bar is fixedly connected to the sliding lug vertical plate, and a steel bar with good tenacity is used as the falling prevention reinforcing bar. After the sliding lug is broken, the falling prevention reinforcing bar is only bent and holds the broken part, the accident that the sliding lug falls off and hurts people is avoided, and the safety coefficient of the sliding lug is greatly improved.
Description
Technical field
The utility model relates to the sliding ear of Anti-fall arbitrary-movement articulator for a kind of rotary drilling rig, belongs to rotary drilling rig accessory kit technical field.
Background technology
Rotary drilling rig is when normally creeping into operation, and arbitrary-movement articulator need to play the guiding role to drilling rod together with unit head.Rig is special when entering rock and creeping into, and drilling rod direction vibrations are all around all larger, can cause sliding ear portions fracture, and serious situation there will be the situation that falls to ground after fracture, even occurs the accident that kills field personnel after dropping.
Current sliding ear mostly adopts the local mode of strengthening, as shown in Figure 1, outer ledge place at sliding ear riser 1 is welded with sliding ear stiffener 2, the bottom, inside edge of described sliding ear riser 1 is welded with nylon sheet installing plate 4, but the vibrations of rig when entering rock and creep into are very large, the more difficult accurate Calculation of impact force being subject in sliding ear place, and space, sliding ear place is subject to certain restrictions, intensity can not be improved a lot, therefore, adopt strengthened sliding ear as shown in Figure 1 still to have phenomenon of rupture.
Utility model content
The technical problems to be solved in the utility model is for the arbitrary-movement articulator of current use, to slide ear intensity can not meet safety requirements, the problem that drops and hurt sb.'s feelings from high-altitude after the sliding ear of arbitrary-movement articulator that may occur during rotary drilling rig work surprisingly ruptures, provides the sliding ear of Anti-fall arbitrary-movement articulator for rotary drilling rig that a kind of safety factor is high.
In order to address the above problem, the utility model by the following technical solutions:
With the sliding ear of Anti-fall arbitrary-movement articulator, comprise sliding ear riser, the outer ledge place of described sliding ear riser is welded with sliding ear stiffener, on described sliding ear riser, is fixedly connected with Anti-fall reinforcing rib.
Below the further improvement of the utility model to technique scheme:
Anti-fall reinforcing rib is arranged on and on sliding ear riser, is positioned at the inner side of sliding ear stiffener or the position in outside.
The lower end of described sliding ear stiffener is connected with horizontal extension portion, and described horizontal extension portion is fixedly connected with the lower edge place of sliding ear riser.Horizontal extension portion lengthens, and encases Anti-fall reinforcing rib, does not affect sliding ear aesthetic property when sliding ear is strengthened.
Further improve:
The bottom, inside edge of described sliding ear riser is welded with nylon sheet installing plate, and the lower end of described Anti-fall reinforcing rib is arranged between horizontal extension portion and nylon sheet installing plate.
Anti-fall reinforcing rib adopts the good reinforcing bar of toughness.After sliding ear fracture, Anti-fall reinforcing rib just occurs crooked and the part of fracture is held, and prevents the generation of casualty accident after dropping, and the safety factor of sliding ear is provided greatly.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of existing sliding ear in the utility model background technology;
Accompanying drawing 2 is the structural representation of the utility model embodiment.
In figure: the sliding ear riser of 1-; The sliding ear stiffener of 2-; 3-Anti-fall reinforcing rib; 4-nylon sheet installing plate; 5-horizontal extension portion.
The specific embodiment
Embodiment, as shown in Figure 2, the sliding ear of Anti-fall arbitrary-movement articulator for a kind of rotary drilling rig, comprise sliding ear riser 1, the outer ledge place of described sliding ear riser 1 is welded with sliding ear stiffener 2, the bottom, inside edge of described sliding ear riser 1 is welded with nylon sheet installing plate 4, and the lower end of described sliding ear stiffener 2 is connected with horizontal extension portion 5, and described horizontal extension portion 5 is fixedly connected with the lower edge place of sliding ear riser 1.
On described sliding ear riser 1, be fixedly connected with Anti-fall reinforcing rib 3.
Anti-fall reinforcing rib 3 is arranged on the position that is positioned at the inner side of sliding ear stiffener 2 on sliding ear riser 1.
The lower end of described Anti-fall reinforcing rib 3 is arranged between horizontal extension portion 5 and nylon sheet installing plate 4.
Anti-fall reinforcing rib 3 adopts the good reinforcing bar of toughness.After sliding ear fracture, Anti-fall reinforcing rib 3 just occurs crooked and the part of fracture is held, and prevents the generation of casualty accident after dropping, and the safety factor of sliding ear is provided greatly.
In above-described embodiment, Anti-fall reinforcing rib 3 can also be arranged on the position that is positioned at the outside of sliding ear stiffener 2 on sliding ear riser 1.
