In order to be more clearly understood to the technical characteristic of the present invention, purpose and effect, now control illustrates this
Bright specific embodiment.
As shown in Figures 1 to 4, the petroleum drilling winch 100 that the present invention is provided, including cylinder 1, in the present embodiment,
It is equipped with central shaft in cylinder 1 vertically, the both sides of cylinder 1 are respectively arranged with the bearing block 11 of bottom fixation, and central shaft is located at
Two ends in the outside of cylinder 1 rotate respectively the bearing block 11 worn by both sides, and the bearing block 11 of both sides carries out turning to cylinder 1
It is dynamic to support；It is wound with the steel wire rope being connected with drill string on cylinder 1, the both sides of cylinder 1 symmetrically and from proximal and distal are linked in sequence
Dynamic device 2 and brake 3, the power set 2 of both sides can synchronously be opened and rotated, and the brake 3 of both sides can be synchronous
Release and braking.The power set 2 of both sides are connected respectively by a clutch 21 with cylinder 1, in the present embodiment, clutch
One end of device 21 is fixedly connected by way of bonded and interference fit with the end of the central shaft of cylinder 1, clutch 21
Folding condition is by clutch cylinder drive control (prior art, figure not shown in).As shown in Figure 1 and Figure 2, each power set 2
Include a gearbox 22, one end of gearbox 22 is connected with clutch 21, in the present embodiment, one end of gearbox 22 leads to
Cross the connection that bonded and interference fit mode is realized with clutch 21；The other end of gearbox 22 is connected with motor
23, motor 23 is double alternating-current variable frequency motors lifted one's head, and according to the frequency control characteristic of alternating-current variable frequency motor, oil drilling is twisted
Car 100 can adopt the service braking that energy consumption of electrical machinery mode of braking be realized in the course of work, i.e., wait need for sending to bore and make a trip
Control the braking of the operating mode of speed；The other end connecting brake 3 of motor 23, brake 3 is used to realize oil drilling
The parking braking (prior art refers to stopping brake during driller's operating position away from keyboard) of winch 100 and safe emergency braking
(prior art refers to that trip crane system reaches to touch down and pounds extreme position and burst emergency and need to stop as early as possible swimming crane system
Braking).The clutch 21 of both sides is in normal operation engagement state, when the gearbox 22 or motor of certain side
23 break down cannot normal work when, brake 3 carries out safe emergency braking, by 21 points of the clutch of side of breaking down
From then release brake 3, using the power set 2 of opposite side cylinder 1, the emersion drill string from well, it is to avoid cylinder 1 are driven
The drill string long-time of upper connection is stagnated in well and causes lock of tool drilling, effectively improves security.Brake 3 is arranged on motor
23 away from cylinder 1 tail end, this connection configuration can utilize the speed change of gearbox 22 become turn round characteristic, realize with less braking
Moment of torsion meets the parking braking of petroleum drilling winch 100 and safe emergency brake request, and then realizes the structure letter of brake 3
Change, beneficial to the reduction of the size of petroleum drilling winch 100, reduce weight and cost input.
The motor of the petroleum drilling winch 100 that the present invention is provided is arranged on power using double tap structures, brake 3
Away from the tail end of cylinder 1, required braking torque reduces device 2, and the optional wide ranges of brake, brake is simple, and size reduces, into
This reduction；The both sides of cylinder 1 of petroleum drilling winch 100 are respectively provided with one group of power set 2 and brake 3, the power set of both sides
It is connected with cylinder by clutch, under normal operating conditions, the synchronization action of power set 2 of both sides, the brake 3 of both sides is same
Step action, when the gearbox 22 or motor 23 of certain side break down cannot normal work when, it is tight that brake 3 carries out safety
Anxious braking, the clutch 21 of side of breaking down is separated, then release brake 3, and the power set 2 of opposite side can be independent
Cylinder 1 is driven, with higher efficiency raising drill string, it is to avoid the drill string long-time connected on cylinder 1 is stagnated in well and causes bit freezing thing
Therefore, effectively improve security；The motor of the petroleum drilling winch that the present invention is provided is alternating-current variable frequency motor, can be by becoming
Frequency modulation speed realizes the service braking of petroleum drilling winch；The overall structure of petroleum drilling winch 100 simplifies, and reduces weight and cost.
