Description

Double-roller well logging prying small roller lifting and rotating structure

Technical Field

The utility model relates to an oil field logging equipment makes technical field, concretely relates to twin drum well logging sled small drum lifts revolution mechanic.

Background

The existing oilfield logging market is generally divided into two parts, one part is land logging, and the other part is marine logging. The land logging winch is divided into a vehicle-mounted logging winch and a skid-mounted logging winch. And the marine logging winch can only work by using a skid-mounted logging winch due to the requirements of transportation and hoisting. The biggest difference between the vehicle and the pry is that the chassis is changed into an engine. The well logging is divided into various conditions, such as open hole well logging, production well logging and the like, and the required well logging cable specifications are different, namely phi 12.7mm, phi 11.8mm, phi 8mm, phi 5.6mm and the like.

Conventional logging truck mostly has a roller structure, for example, a logging truck disclosed in patent No. CN206888971U, which includes a truck, an electric control hydraulic rod a, a beam platform, an electric control hydraulic rod b, a pulley fixing frame, a logging instrument and a logging cable mechanism, and uses a single roller structure, a roller motor drives a roller to rotate, and a logging cable wound on the roller is discharged a little bit, but the single roller is only suitable for winding a single-specification steel wire or cable, in order to achieve the purpose that one logging truck can perform multiple operations, one truck (sled) has two purposes, and cost is saved, it is necessary to add a roller on the basis of the single roller cable logging truck to achieve the structure of large and small rollers, two winches used at present are a double-roller structure with two rollers side by side, the two rollers have a large width formed side by side, and occupy a large space, meanwhile, when the double-roller logging pry is matched with a crane and the like to work, a steel wire slides out from the central position of the winch, because the two rollers are arranged side by side, the offset between the steel wire and the central position is larger, the abrasion of the steel wire is larger, and the hoisting stability is influenced, so that a structure for separating the two rollers is designed, the large winch roller and the small winch roller are arranged in parallel, the two rollers are both positioned at the central position, the output of the steel wire is more stable, in order not to influence the cable rope outlet problem of the large winch roller, the height of a small winch which needs to be increased later cannot be higher than the bottom diameter of the large winch roller, for example, a novel logging truck disclosed in the patent No. CN 206298424U uses the two winch rollers, can use cables with various specifications, but the small winch rollers are lower in height, and influence the observation of a winch worker on the working condition of the rollers, therefore, the double-roller logging pry small roller lifting rotary structure is provided, and can drive the small rollers to lift, and the switching of two working states is realized.
