Abstract
The utility model relates to a rope protecting device of a skid-mounted drilling rig and used for derrick lifting. The rope protecting device of the skid-mounted drilling rig and used for the derrick lifting comprises supports, a wheel spindle, copper sleeves, oil cups, bolts and nuts, wherein the number of the supports is two, the two supports are connected with two ends of the wheel spindle respectively through the copper sleeves and the oil cups, and the two supports are both fixed on a derrick through the bolts and the nuts. Compared with the prior art, the rope protecting device of the skid-mounted drilling rig and used for the derrick lifting has the advantages of being low in cost, simple in structure, reasonable in design, convenient to machine, strong in practicality, capable of effectively reducing the wearing coefficient of a lifting rope and prolonging the service life of the lifting rope and avoiding occurrence of major accidents, and suitable for derricks of various types and specifications.
Description
Technical field
The utility model relates to the safety device that sledge dress drilling derrick hoists, particularly a kind of sledge dress drilling derrick ward off rope device.
Background technology
At present, sledge dress rig is when the wellsite operation of oil field, derrick telescoping is a very important operation in the dead work before spudding in, big lifting rope should be checked before using, if discovery fracture of wire, injure by a crashing object, steel rope is beaten and is turned round, answer withdraw from use during phenomenons such as localized wear or wirerope diameter minimizing 5%, deposited after simultaneously big lifting rope uses 2 years, domestic recommended replacement, also the big rope of suggestion is changed after using and hoisting for 5 times, for example, country such as Turkey hard and fast rule, big lifting rope must be changed after using and hoisting for 1 time, because the structural factor of derrick, big lifting rope during derrick telescoping rubs with derrick easily, causes the big lifting rope steel wire fracture, big lifting rope disconnection and generation grave accident.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, easy to process, reduce the unnecessary worn-down derrick of big lifting rope ward off rope device.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of sledge dress drilling derrick ward off rope device, comprise bearing, wheel shaft, copper sheathing, lubricating cup, screw bolt and nut, described bearing has two, and two bearings are connected with the wheel shaft two ends respectively with lubricating cup by copper sheathing, and two bearings all are fixed on the derrick by screw bolt and nut.
Compared with prior art, the beneficial effects of the utility model are:
A kind of sledge dress drilling derrick ward off rope device, have low, simple in structure, reasonable in design, easy to process, the practical characteristics of cost, effectively reduced the abrasion factor of big lifting rope, improve the service life of big lifting rope, avoid the generation of grave accident, be applicable to multiple model specification drilling derrick simultaneously.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model;
Fig. 2 is a use scheme drawing of the present utility model.
1-bearing, 2-wheel shaft, 3-copper sheathing, 4-lubricating cup, 5-bolt, 6-nut, 7-derrick, 8-big lifting rope
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further specified:
As shown in Figure 1, a kind of sledge dress of the utility model drilling derrick ward off rope device, comprise bearing 1, wheel shaft 2, copper sheathing 3, lubricating cup 4, bolt 5 and nut 6, bearing 1 has two, two bearings 1 are connected with wheel shaft 2 two ends respectively with lubricating cup 4 by copper sheathing 3, and two bearings 1 all are fixed on the derrick 7 by bolt 5 and nut 6.
As shown in Figure 2, when using the utility model, big lifting rope 8 invests wheel shaft 2 surfaces; when big lifting rope 8 hoists; drive wheel shaft 2 and relatively rotate, wheel shaft 2 is given the fulcrum of 8 one arc transition of big lifting rope simultaneously, and the friction of big lifting rope 8 and derrick 7 is protected and avoided to actv..
Above described only be groundwork of the present utility model, be not that the utility model is imposed any restrictions, everyly it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme according to the utility model.
