Abstract
The utility model discloses an extractor for a brake safety hook of a beam pumping unit. The extractor is applied to the operation of extracting the brake safety hook of the beam pumping unit. A fixing block is rectangular, one long edge side of the fixing block is provided with a rectangular concave groove, the concave groove divides the fixing block into two rectangular blocks, and a transverse connecting block is arranged between the two rectangular blocks; the middle part of one rectangular block is provided with a screw hole, a screw is arranged in the screw hole and passes through the screw hole, and a rotating handle hole is formed at one end of the screw; and two horizontal screw holes are symmetrically distributed on one side of the other rectangular block, a fixing bolt is arranged in each horizontal screw hole and passes through the horizontal screw hole, one end of each of the fixing bolts is positioned in the groove, and a hexagonal wrench head is arranged at the other end of each of the fixing bolts. The utility model has the advantage that the extractor can quickly extract brake safety hooks of pumping units from concave locked grooves.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly the special-purpose maintenance tool of beam pumping unit is a kind of beam pumping unit brake safety hook puller.
Background technology
Because the beam pumping unit brake failure causes the case of personal security accident in each oil field generation to be arranged all, for preventing the appearance once more of similar accident; The employee according to the requirement of safety regulation for operations, must be cut off the power supply when the daily maintenance oil pumper; The brake of tension oil pumper; The safety hook that must will brake simultaneously locks, and to prevent brake failure, causes personnel's casualty accident.But in the operation, tend to occur oil pumper brake safety hook and be difficult to from the matrix locked groove, take out at the scene, the operative employee has to adopt crowbar to prize or coil methods such as belt of oil pumping machine, when running into large-scale oil pumper, then can only adopt crane that safety pin is taken out.Not only increase production cost and personnel labor, bring potential safety hazard, rate when also having influenced the running of oil pumper.Therefore during the employee operates at the scene, can often occur safety hook yet and put into the phenomenon of matrix locked groove not according to operational procedure, employee's safety in operation is not protected.
The utility model content
The purpose of the utility model is: a kind of beam pumping unit brake safety hook puller is provided, and the brake safety hook of light taking-up beam pumping unit reduces working strength of workers and production cost, the rate when security of raising work and the running of oil pumper.
The technical scheme that the utility model adopts is: beam pumping unit brake safety hook puller; Comprise fixed block, set bolt and screw rod; It is characterized in that: fixed block is a cuboid; One side has the concave groove of a cuboid on the long limit of fixed block, and concave groove is divided into two rectangular blocks to fixed block, between two rectangular blocks horizontal contiguous block is arranged; A vertical screw is arranged at the middle part of a rectangular blocks, vertically in the screw screw rod is arranged, screw rod passes screw, at an end of screw rod the rotary handle hole is arranged; Be symmetrically distributed with two horizontal screws in the side of another rectangular blocks, a set bolt is arranged in each horizontal screw, set bolt passes horizontal screw, and an end of set bolt is in concave groove, and the other end of set bolt has the hexagon head.
The length of described fixed block is 80mm, and width is 70mm, and thickness is 60mm; Described concave groove length is identical with the width of fixed block, and width is 30mm, and the degree of depth is 40mm, and described screw rod has the M20 screw thread; Described set bolt is the M16 bolt.
The use of summary beam pumping unit brake safety hook puller.When oil pumper brake safety hook is locked in can't take out in the groove time; Snap in the safety hook head end in the concave groove of puller, tighten two set bolts safety hook is blocked firmly, be rotated down the screw rod of puller then; Puller is stressed to move upward, until from groove, extracting safety hook.
The beneficial effect of the utility model: the utility model beam pumping unit brake safety hook puller, can be fast with oil pumper safety hook the extracting from the concavity locked groove of braking.Effectively avoided because safety hook is locked, the problem of having to use crane could safety hook be extracted has been practiced thrift cost.Puller has been arranged simultaneously, and the employee can be relieved puts into safety hook the matrix locked groove, increases the security of operation, has reduced working strength of workers, rate when also having increased simultaneously the running of oil pumper.
