Abstract
The utility model discloses a kind of oil-well rig single-sheaved block tourist bus, it includes the full symmetric right plate group of shape, structure, left plate group, monolithic pulley is installed in the middle of the right plate group, left plate group, pulley is assemblied on pulley spindle by bearing, the two ends of pulley spindle are separately fixed at right plate group, in left plate group, the top of pulley is provided with the upper guard board being connected with right plate group, left plate group, and the lower section of pulley is provided with the lower backplate being connected with right plate group, left plate group.The utility model structure is novel, using flexible, by the paired symmetry transformation of single-sheaved block tourist bus can be movable pulley or fixed pulley according to actual condition in drilling process, be that rope system Fast transforms can be achieved without wire rope handling again, greatly improve the operating efficiency of motor.
Description
Technical field
The utility model is related to oil drilling machine equipment technical field, specifically a kind of oil-well rig single-sheaved block
Tourist bus.
Background technology
Oil-well rig with tourist bus be inside derrick above and below reciprocating running block, the structure of tourist bus is typically all
Multiple pulleys are equipped with by rolling bearing on single-sheaved block axle.This tourist bus structure is fixed, and traveling system structure, rope system are all solid
Fixed, in drillng operation when lifted load changes, it is impossible to make winch according to the different conversion rope systems of lifting load
Motor is run in high efficient district all the time, and this many pulley-type tourist buses cause that system job form is single, and motor working efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of oil-well rig single-sheaved block tourist bus, can be matched somebody with somebody according to the size of drilling well load
An appropriate number of tourist bus is put, motor work, to improve system job form, can be improved with auto-changing rope system in drilling process
Efficiency.
To reach above-mentioned purpose, technical solution adopted in the utility model is：
A kind of oil-well rig single-sheaved block tourist bus, it includes the full symmetric right plate group of shape, structure, left plate group,
Monolithic pulley is installed in the middle of the right plate group, left plate group, pulley is assemblied on pulley spindle by bearing, the two of pulley spindle
End is separately fixed at right plate group, in left plate group, and the top of pulley is provided with the upper shield being connected with right plate group, left plate group
Plate, the lower section of pulley is provided with the lower backplate being connected with right plate group, left plate group.
It is preferred that, the lower section of the lower backplate is provided with bearing pin, and the two ends of bearing pin are separately mounted to right plate group, left plate group
On.
Traditional running block formula tourist bus is improved to single pulley type tourist bus by the utility model, can be in drilling process not
Again it is movable pulley or fixed pulley by the paired symmetry transformation of single-sheaved block tourist bus according to the situation of real load on the premise of wire rope handling,
With the purpose for reaching Fast transforms rope system, improving motor working efficiency.
The beneficial effects of the utility model：
（1）The utility model structure is novel, using flexible, can be according to actual condition by the paired symmetry transformation of single-sheaved block tourist bus
For movable pulley or fixed pulley, the conversion of rope system can be realized automatically without wire rope handling again, the operating efficiency of motor is greatly improved；
（2）Backplate under the utility model is installed between right plate group and left plate group, ensure that safe wire cable is made
Industry, improves the reliability of equipment；
（3）Bearing pin below lower backplate is used for the connection that the utility model drives support with top.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model；
Fig. 2 is structural decomposition diagram of the present utility model in Fig. 1；
Fig. 3 is front view of the present utility model in Fig. 1；
In figure：1st, upper guard board, 2, right plate group, 3, bearing, 4, pulley spindle, 5, pulley, 6, lower backplate, 7, bearing pin, 8, left
Side plate group.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of oil-well rig single-sheaved block tourist bus as shown in Figure 1 to Figure 3, it includes the full symmetric right side of shape, structure
Monolithic pulley 5 is installed in the middle of side plate group 2, left plate group 8, right plate group 2, left plate group 8, pulley 5 is assemblied in by bearing 3
On pulley spindle 4, the two ends of pulley spindle 4 are separately fixed at right plate group 2, in left plate group 8, and the top of pulley 5 is provided with and right side
The upper guard board 1 that plate group 2, left plate group 8 are connected, the lower section of pulley 5 with right plate group 2, left plate group 8 provided with being connected
Backplate 6.
The lower section of lower backplate 6 is provided with bearing pin 7, and the two ends of bearing pin 7 are separately mounted to right plate group 2, in left plate group 8, use
The connection of support is driven with top in tourist bus.
The utility model structure is novel, using flexible, in drilling process can according to actual condition by single-sheaved block tourist bus into
It is movable pulley or fixed pulley to symmetry transformation, is that rope system Fast transforms can be achieved without wire rope handling again, greatly improves motor
Operating efficiency.
