But the prior art take above-mentioned patent documentation as representative, it can not be applicable to the lifting to borehole instruments string, and borehole instruments string cannot be connected with existing lifting device, and borehole instruments easily comes off and even loses.
Summary of the invention
The utility model is intended to for the existing defect of above-mentioned prior art and deficiency, a kind of lifting device is provided, adopts the utility model, can realize the lifting to borehole instruments string, and can connect by fine hell borehole instruments series winding, prevent that the situation that comes off, loses from occurring.
The utility model is by adopting following technical proposals to realize:
A kind of lifting device, it is characterized in that: comprise hoisting device main body, stage clip, stop screw, balance rotating bar, suspension ring one, suspension ring two and screw rod, wherein, in hoisting device main body, be provided with hollow container structure, one end of hoisting device main body is connected with lock hook, compression spring sleeve is in hoisting device main body and lock hook, and one end of stage clip is against on the hook of lock hook, stop screw is fixed in hoisting device main body, the other end of stage clip is against on described stop screw, suspension ring two are connected with hoisting device main body screw, and screw rod is connected with described suspension ring two and is positioned at described container structure, one end of balance rotating bar is connected with suspension ring one, the other end stretches in described container structure and is connected with described screw flight.
The two ends of described balance rotating bar are processed with tapped bore, and on balance rotating bar, described suspension ring one are installed in thicker one end, and fix with screw thread glue.
The size of described suspension ring one is little compared with the size of suspension ring two.
Compared with prior art, the beneficial effect that the utility model reaches is as follows:
The lifting device that the utility model adopts " hoisting device main body, stage clip, stop screw, balance rotating bar, suspension ring one, suspension ring two and screw rod " to form, it has following technique effect:
1, the lock hook overcoat that the utility model adopts has stage clip to make hold-down mechanism, and can effectively prevent from lifting time, borehole instruments comes off.
2, the balance rotating bar that the utility model adopts, can drive instrument string to be rotated in lifting device.
3, hoisting device body interior of the present utility model has container structure, and thus, in transportation or used time not, balance rotating bar can be fixed in hoisting device, can not lose, and can prevent the Lift hook distortion of colliding with.
4, the selected balance rotating bar of the utility model can indicating instruments string keyway direction.
Accompanying drawing explanation
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
Mark in figure:
1 be hoisting device main body, 2 for stage clip, 3 is for stop screw, 4 is for balance rotating bar, 5 is for little suspension ring, 6 are for large suspension ring, 7 are for screw rod, 8, hook, 9, container structure.
The specific embodiment
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure of description, the utility model comprises hoisting device main body 1, stage clip 2, stop screw 3, balance rotating bar 4, suspension ring one, suspension ring two and screw rod 7.
In hoisting device main body 1, be provided with hollow container structure 9, hoisting device body 1 is if open circles tubular, container structure 9 is exactly a columnar cavity, one end of hoisting device main body 1 is connected with lock hook, stage clip 2 is enclosed within hoisting device main body 1 and lock hook, and one end of stage clip 2 is against on the hook 8 of lock hook, and stop screw 3 is fixed in hoisting device main body 1
There is negative thread hoisting device main body 1 one end, can be connected with large suspension ring 6; The other end is processed with lock hook.The each also circle of pressing in two ends of stage clip 2 polishes, and spring silk incision position at one end welds breach with electric welding full, and polishes.Stage clip 2 is enclosed within to hoisting device main body 1) the one end that has lock hook, and stage clip 2 one end of welding and polishing and one end that has lock hook of hoisting device main body 1 are consistent.And mounting limit screw 3 in position, prevent that stage clip 2 and hoisting device main body 1 from relatively moving.
Screw rod 7 is arranged in the tapped bore of large suspension ring 6 correspondences, and dead with screw thread glue.Then the large suspension ring 6 with screw rod 7 are arranged in the tapped bore of hoisting device main body 1 one end, and dead with screw thread glue.
The two ends of balance rotating bar 4 are processed with tapped bore, and little suspension ring 5 are installed in thick one end, and dead with screw thread glue.Then by the balance rotating bar 4 with little suspension ring 5, insert the container structure 9 of hoisting device main body 1 from thin one end, and be spun on the screw rod 7 being fixed on large suspension ring 6.
