Abstract
The utility model relates to a rope guarding device of a two-floor working base, belonging to a field of an oil drilling assistant device, which comprises a footplate, a turnover crossbeam, pins, an ear plate and a roll bar. The foot plate is connected with the two-floor main body bracket; the turnover crossbeam is connected with the crossbeam of the two-floor working base through the pins and the ear plate so that the sliding friction caused by hydraulic winch steel wire ropes turns into rolling friction. The problems of the prior art that the hydraulic winch steel wire ropes are easily locked at the connector between two rectangle foot plates of the rope guarding device and the connector between the foot plates and the crossbeam which is solved by operators by hand with the problem of danger are solved. The rope guarding device of the two-floor working base not only decreases the wear and tear of the steel wire ropes and the two-floor working base, but also decreases the danger of the drilling operators. The utility model is fit for any two-floor working base of an automotive drilling rig, a work over rig, a modular drilling device and any ocean-module drilling device.
Description
Affiliated technical field:
The utility model relates to a kind of two layers of workbench ward off rope device that are applied to various truck-mounted drill rigs, workover rig, module drilling machine and various marine rig, belongs to oil-well rig servicing unit field.
Background technology:
In oil drilling and workover treatment process, often use the hydraulic pressure puffer to realize the less important works such as lifting of drilling tool, rig tool.Because the particularity of operation, quadruple board platform is nearer apart from well head, and seldom ward off rope device is set, and perhaps the ward off rope device effect of She Zhiing is undesirable.The ward off rope device of the quadruple board platform of existing employing is the telescopic tube form, has the following disadvantages:
1. the hydraulic wireline winch wire rope is easily blocked in two rectangle pedal junctions and pedal and crossbeam junction, causes steel rope abrasion severity, and is fragile.And must remove by hand by operating personnel, but since two layers of workbench aloft, higher apart from ground, operation has certain danger.
2. its telescopic tube is installed on the crossbeam, and the centre has the space unavoidably, and wire rope passes two gaps between the telescopic tube easily and seals in the fingerboard place, thereby the wearing and tearing wire rope damages fingerboard.
Along with the development of rig, above-mentioned ward off rope device more and more is not suitable for the requirement of drillng operation.And the wearing and tearing of wire rope and quadruple board platform are also influenced the pursuit of modern drillng operation to benefit.
Summary of the invention:
The purpose of this utility model is: rolling friction is provided when providing a kind of wire rope that makes hydraulic wireline winch to move, ward off rope device is reduced the wearing and tearing of wire rope and two layers of workbench, wire rope is not stuck, and reduces by two layers of workbench ward off rope device of drill-well operation personnel's danger.
The utility model is to realize above-mentioned purpose by following technical solution.
These two layers of workbench ward off rope device are made up of operating pedal, turning crossbeam, pin, otic placode and rolling bar, it is characterized in that: a side of turning crossbeam is equipped with two block operations pedals, turning crossbeam connects the crossbeam of two layers of workbench by pin and otic placode, one rolling bar is housed on the turning crossbeam, and pedal two inner edges are the obtuse angle at the angle at A and B point place.
The utility model compared with prior art has following beneficial effect:
1. in the rig operation, when the hydraulic wireline winch wire rope was met an A or D place, pulling force will make wire rope slide to B or C place along swash plate.Wire rope just can roll along rolling bar like this, and changing sliding friction is rolling friction, thereby reduces the friction to wire rope, increases the service life.
2. owing to avoided the use of rectangle pedal among the design, wire rope just can not be stuck in the place, summit of rectangle pedal, has reduced the friction to wire rope.And avoid operating personnel at height in the air to the unfreezing of wire rope, reduced the danger of operating personnel's operation.
3.B, the crossbeam at C place can also stop that wire rope seals in fingerboard one side, avoids damaging fingerboard and wire rope.
Description of drawings:
Fig. 1 is the structural representation of two layers of workbench ward off rope device;
Fig. 2 is I place enlarged drawing.
Among the figure: 1. operating pedal, 2. turning crossbeam, 3. pin, 4. otic placode, 5. rolling bar.
The specific embodiment:
These two layers of workbench ward off rope device are made up of pedal (1), turning crossbeam (2), pin (3), otic placode (4) and rolling bar (5).Operating pedal (1) directly links to each other with two layers of workbench body frame body, and turning crossbeam (2) links to each other with crossbeam on two layers of workbench by pin (3) and otic placode (4).
In the rig operating process, when the hydraulic wireline winch wire rope was met an A or D place, pulling force will make wire rope slide to B or C place along swash plate.Wire rope just can roll along rolling bar (5) like this, and changing sliding friction is rolling friction, thereby reduces the friction to wire rope, increases the service life.And the turning crossbeam (2) at B, C place can also stop that wire rope seals in fingerboard one side, avoids damaging fingerboard and wire rope.In addition, owing to avoided the use of rectangle pedal, wire rope just can not be stuck in the place, summit of rectangle pedal, has reduced the friction to wire rope.And avoid operating personnel at height in the air to the unfreezing of wire rope, reduced the danger of operating personnel's operation.
