Description

Multifunctional well testing vehicle with inclined winch

Technical Field

The utility model relates to an oil field well testing operation car.

Background

The well testing vehicles in the current market are of two types, one type is the traditional well testing vehicle without a truck-mounted crane; the other type is a well testing vehicle integrated with a truck-mounted crane, and the well testing vehicle has the great disadvantage that the truck-mounted crane is offset by the well testing vehicle, namely the truck-mounted crane is not arranged on a vehicle girder in a span way, or is deviated to a main driving side or a secondary driving side. The deviation of the truck-mounted crane is mainly to facilitate the winch in a winch cabin to discharge steel wires or cables, but the vehicle with the deviation of the truck-mounted crane has a great problem that the gravity center of the whole vehicle deviates to one side of the longitudinal center line of the vehicle, and the gravity center deviation brings about the result that the left side and the right side of a chassis frame, a leaf spring and a tire are uneven when the vehicle is in a static state, and the situation of keeping the state for a long time can cause the girder and accessories of the chassis to generate permanent deformation and damage the chassis; the result brought by the driving state of the vehicle is that the left and right weight measurement of the vehicle is unbalanced when the vehicle turns or drives, and the vehicle is easy to turn over and unsafe.

The utility model has the advantages that:

firstly, a truck-mounted crane is arranged at the tail part of an auxiliary frame in a centering way, a winch roller is obliquely arranged 15-20 degrees relative to the longitudinal central line of an automobile, and a winch is arranged on an auxiliary girder, so that interference between a steel wire rope discharged by the winch and the central truck-mounted crane is avoided; the problem of current well testing car truck-mounted crane biasing vehicle one side is solved.

And secondly, the side wall at the tail part of the auxiliary frame can rotate locally, the canvas is covered after the side wall is closed during parking, the rotatable side wall is opened during field operation, the cable arrangement space is increased in a winch cabin, and the view field area of an observation well mouth is increased through an observation window. The steel wire or the cable which is discharged by the winch is ensured to avoid the truck-mounted crane and not interfere with each other

Third, the utility model discloses on the basis of well testing car, integrateed the truck-mounted and hung, the truck-mounted hangs the centering and arranges at the sub vehicle frame afterbody, has overcome the biased defect of current well testing car truck-mounted and hung, and the inside oblique formula mid-board in carriage separates the carriage for two cabins in front and back, and the front deck is the operating compartment, and the backshell is the winch cabin, and the winch cabin is close to left side wall afterbody and can rotate, and it lifts by crane work to hang by the cable when accomplishing the well testing operation by the steel wire that the winch discharged or cable.

fig. 1 is a schematic view of the structure of the driving (parking) state of the present invention.

Fig. 2 is a top view of fig. 1.

Fig. 3 is a side view of fig. 1.

The specific implementation mode is as follows:

as shown in fig. 1-3, a multifunctional well testing vehicle with an inclined winch is formed by modifying a second-class vehicle chassis, and mainly comprises a vehicle chassis 1, an auxiliary frame 2, a truck-mounted crane 3, an operation cabin 4, a winch 5, a winch cabin 6, a measuring system 7, a rope arranger 8, a hydraulic system 9, an electrical system 10, a force taking system 11 and a rotatable side wall 12, wherein the auxiliary frame 2 is installed on the vehicle chassis 1, a carriage is arranged on the auxiliary frame 2 and is installed in the middle front part of the auxiliary frame, an inclined intermediate wall in the carriage divides the carriage into a front cabin and a rear cabin, the front cabin is the operation cabin 4, the rear cabin is the winch cabin 6, the operation cabin 4 and the winch cabin 6 are installed in the front part of the auxiliary frame, the inclination angle of the intermediate wall is consistent with that of the winch 5, the truck-mounted crane 3 is installed in the middle part of the auxiliary frame 2 to keep the left and right balance of the center of gravity and ensure the driving safety. The winch 5 is arranged in the winch cabin 6 and fixed on the auxiliary frame 2, the vertical bisector of the winch 5 forms an included angle of 15-20 degrees with the longitudinal central line of the vehicle, and the winch cabin 6 can rotate close to the tail part of the left side wall. The measuring system 7 and the rope arranger 8 are placed in the winch compartment 6. The partition wall of the front cabin and the rear cabin is provided with an observation window, the inclination angles of the observation window and the winch roller are kept consistent, and an operator can conveniently observe the conditions of the steel wire discharge and the well mouth during operation. The power take-off system 11 is positioned at the rear part of the chassis gearbox, the hydraulic system 9 and the electric system 10 are positioned inside the operation cabin 4 and the winch cabin 6, and the power of the truck-mounted crane 3 and the winch 5 is provided by the hydraulic system 9. The power takeoff transmits the power of an automobile engine to a hydraulic system 9 oil pump through a transmission shaft, and the oil pump drives a motor and a hydraulic cylinder to work.

During operation, the vehicle is parked at a place 12-13 meters away from a wellhead, and the winch is over against the wellhead. And (3) putting down the hydraulic support legs of the truck-mounted crane (3) to keep the vehicle stable and safe, opening the rotatable side wall (12), and starting the rope arranger (8) to enable the winch (5) to discharge the well testing steel wires. And the well testing steel wire wound on the winch 5 sequentially passes through the measuring system 7, the ground pulley and the blowout prevention pipe, and the well testing instrument is put into the underground through the wellhead device.
