Description

Winch device of test well vehicle

The utility model belongs to the tool car of oil gas field well logging usefulness.

In order to obtain the complete means of production of oil-water well, as data such as the flowing pressure of measuring oil-water well, flow, bottom hole temperature (BHT), intake profiles, in well, be lowered to tester by test carriage, measure as pressure gauge, thermometer, flow meter etc.These test jobs must be finished in the open air, so well testing truck is a kind of special automobile, it is at automobile inside the well testing winch to be arranged, and various test instrumentations and testing tool are realized well logging work.The winch of well testing truck is with the capital equipment in the logger lower going-into-well, on the cylinder of winch, be wound with sufficiently long steel wire or cable, logger is connected on the steel wire head, put into well by the fixed pulley that is installed in well head again, therefore, the cylinder of winch must be in line with the fixed pulley of well head, and logger is G.I.H smoothly.Well testing winch of the prior art often adopts SG6000 type or 134A type, its operating principle as shown in Figure 1, the power of automobile transfer case 1, by universal coupling shaft 2, pass to axle 3, drive head sprocket 4 and rotate, again by hinge wheel 5, drive winch drum 6 and rotate, put down or trip out the instrument that connects on the cylinder steel wire.The winch of this well testing truck, its shortcoming is that winch is fixed on the truck board, steel wire or cable can only stretch out from the vehicle window of well testing truck with fixed-direction, have only the railway carriage of working as well testing truck vertical with the direction of well head fixed pulley, steel wire on the winch drum or cable are in line with the well head fixed pulley, logger is G.I.H smoothly, therefore well testing truck must start on the well site back and forth, the position of car could be ajusted, limited to by the well site, waste time and energy, as the road mire, well testing truck is when testing, and position in the well site is more difficult ajusts for it, brings difficulty to well logging.

The utility model is fixed on shortcoming on the carriage bottom plate at well testing winch in the prior art, be designed to and in railway carriage, rotate arbitrarily, and can be fixed on the novel well testing winch in any orientation, overcome well testing truck of the prior art and ajusted the shortcoming of orientation difficulty in the well site, only well testing truck need be stopped in the well site to more convenient position, by adjusting the direction of well testing winch, be easy to make winch and well head pulley then, be lowered to logger smoothly good position.

The utility model foot is realized like this: adorning one on the railway carriage chassis can be equipped with winch drum around the winch chassis that splined shaft arbitrarily rotates on the chassis, sprocket wheel and brake bar are equipped with brake(-holder) block and universal wheel under it.By the operation control lever, the winch chassis can be fixed on any position.

To closing accompanying drawing the utility model is further described below:

Fig. 1 is the winch transmission schematic diagram of existing well testing truck.

Fig. 2 is structure of the present utility model and transmission schematic diagram.

The utility model is by transfer case 1, universal coupling 2, head sprocket 4, hinge wheel 5, winch drum 6, power transmission shaft 7,3,20,21, bevel gear 9,19, bearing 8,22,25,26, the big spy 10 of automobile, brake(-holder) block 11, brake hubs 12, universal wheel 13, car floor 14, rotating chassis 15, brake bar 16, brake bar fastening devices 17, splined shaft 18, chain 23, clutch 24 constitutes.

Hole, one garden is arranged on the automobile chassis 14, and garden dish type rotating chassis 15 is installed in above it.Winch drum 6, hinge wheel 5, head sprocket 4, bevel gear 19 and brake bar 16 etc. are installed in above the rotating chassis 15, at rotating chassis 15 positive centers bearing 25 is housed, bearing 26 is housed on the automotive frame 10, and they cooperate with the splined shaft 18 that connects bevel gear 9 and 19, and rotating chassis 15 can arbitrarily be rotated around splined shaft 18.Below the rotating chassis 15 symmetry universal wheel 13 is housed, it can roll on automobile chassis 14.Brake bar fastening devices 17 is installed in brake bar 16 above the chassis 15, brake(-holder) block 11 below it is connected, by 16 operations of system fortune bar, brake hubs 12 on making it and being fixed on automotive frame 10 cooperates, rotating chassis 15 can be stopped and being fixed on any position, make its position, chassis in the well logging process keep constant.Axle 7 connects with transfer case 1, and axle 3 is fixing by bearing 8, connects with bevel gear 9, and universal coupling 2 is connected axle 7 or separate with axle 3.Axle 20 is fixing by bearing 22, and an end connects with bevel gear 19, and the other end connects head sprocket 4, and hinge wheel 5 coaxial 21 connects, and by clutch 24 operations, drives cylinder 6 and rotates, and hinge wheel 5 drives its rotation by chain 23.

During well logging, well testing truck is reached the appropriate location in well site, the steel wire of logger with winch drum 6 connected, and take-off the brake bar 16 is stirred rotating chassis 15 gently, make winch drum 6 in line with the fixed pulley of well head, steel wire is passed the well head fixed pulley, the instrument G.I.H, pulling brake bar 16, brake(-holder) block 11 is cooperated with brake hubs 12, just that rotating chassis 15 is fixing.Universal coupling 2 closes, make the power of transfer case 1 pass to axle 3 by axle 7, drive bevel gear 9 rotations and make splined shaft 18 with its rotation, driving bevel gear 19 again rotates, making axle 20 drive head sprocket 4 with its rotation rotates, by chain 23 power is passed to hinge wheel 5 and make its rotation, drive winch drum 6 by axle 21 and rotate, the instrument G.I.H of steel wire and connection thereof.When well logging work finishes instrument need be risen up the time, by clutch 24 operations, make winch drum 6 backward rotation, steel wire is wrapped on the cylinder 6 trips out instrument, draw back brake bar 16 then, rotating chassis 15 can be adjusted the position arbitrarily again.

The utility model has the advantages that easy and simple to handle, only need the driver car to be parked in the appropriate location in well site, gently stir the winch chassis with have gentle hands, just can be easy to winch drum is adjusted to a straight line with the direction of the fixed pulley of well head, both enlarged the stop position of well testing truck, save again the time of ajusting car, alleviated simultaneously labour intensity.
