Abstract
The utility model relates to a balancing block regulation tool for a beam-pumping unit, which is used for oil pumping operation in oil fields in petroleum industry and can solve the problems of long operation time, high work intensity and high risk of the balancing block regulation of the beam-pumping unit. The balancing block regulation tool has the advantages that a base of the regulation tool is fixed on a T-shaped groove of a crank through square locking screw bolts and thick locking screw nuts, the base is connected with a screw rod through two lower support frames, one end of the screw rod is provided with a propping locknut and two thrust bearings, the end part of the screw rod is provided with a handle, the upper side of the screw rod is connected with a top end through two upper support frames, a through hole is arranged on the top end and is used for installing a clamping tool, and the top end is in contact with a balancing block. The balancing block regulation tool has the advantages that the balancing block can be conveniently and fast moved to a required position, the regulation operation time is reduced, the work intensity is reduced, the influence on the oil well yield during machine halt because of balancing block regulation is reduced, the structure is compact, and the balancing block regulation tool is safe, reliable, economic and practical when being used for the oil pumping operation in the oil fields.
Description
Technical field
The utility model relates to a kind of beam pumping unit balance weight adjustment means that is used for the petroleum industry oil field operation.
Background technology
In production is recovered the oil in the oil field, because changing, dynamic factors such as formation condition, pit shaft working condition and production well proration can destroy the original equilibrium state of oil pumper, for guaranteeing the upper and lower stroke load of oil pumper evenly, the motor running current is steady, in the application life of prolongation equipment, the position of balance of well pumping unit piece on crank needs often to adjust.The method of present on-the-spot mobile balanced block is comparatively original, needs 3 to 4 people's operations, shuts down earlier crank is stopped behind suitable position; check brake, unload loose fixed screw, unload lock dog; prizing the balance weight bottom with crowbar, beaing balance weight with sledge hammer again and move forward.Because balance weight has several tons of weights, therefore, prize very slowly, labour intensity is big, operational danger is big, causes personal injury easily, and the operating time is long, economic benefit is low.
Summary of the invention
The purpose of this utility model: when regulating in order to solve the beam pumping unit balance weight activity duration long, labour intensity reaches the big problem of danger greatly, the spy provides a kind of convenient and swift, safe and reliable beam pumping unit balance weight adjustment means.
To achieve these goals, the technical solution adopted in the utility model is: a kind of beam pumping unit balance weight adjustment means, by locking square bolt, locking high nut, base, screw rod, upper bracket, lower carriage, thrust bearing, top locknut, top and clamping device being formed, it is characterized in that: the base of adjustment means is fixed on the crank T type groove with locking square bolt and locking high nut; Base connects with two lower carriages and screw rod, is equipped with top locknut and two thrust bearings at screw rod one end, and screw end head is equipped with handle; The screw rod top connects with two upper brackets and top, has a through hole on the top, and clamping device is installed, and the top contacts with balance weight.One end of clamping device is provided with moving jaw, and the other end is provided with regular jaw, the middle clamping device screw rod of installing.
The utlity model has following beneficial effect: owing to utilize the principle of scissors jack, turning handle does not need very big power can finish the adjusting operation of balance weight (1); (2) the utility model has reached the designing requirement of adjustment piece, efficiently solves the shortcoming that wastes time and energy and very easily have an accident when existing balance weight adjustment means is used; (3) utilize this adjustment means, can conveniently balance weight be moved to desired location, reduce the leveling activity duration, reduce labour intensity, reduced the oil well output in the time of to shut down because of the adjustment piece; (4) this adjustment means has compact conformation, is used for the cost-effective advantage of oil field operation.
Description of drawings
Fig. 1 is the mounting structure schematic diagram that the utility model promotes beam pumping unit balance weight adjustment means.
Fig. 2 be this adjustment means crank T type groove 12 to view.
Fig. 3 is the mounting structure schematic diagram that the utility model promotion beam pumping unit balance weight adjustment means of clamping device is installed.
Fig. 4 is the utility model clamping device 13 structural representations.
Among the figure, 1-locking square bolt, 2-locking high nut, 3-base, 4-lower carriage, 5-handle, 6-thrust bearing, 7-to top locknut, 8-screw rod, 9-upper bracket, 10-top, 11-balance weight, 12-crank T type groove, 13-clamping device, 14-moving jaw, 15-clamping device screw rod, 16-regular jaw.
The specific embodiment
Shown in figure, this adjustment means comprises locking square bolt 1, locking high nut 2, base 3, lower carriage 4, handle 5, thrust bearing 6, to top locknut 7, screw rod 8, upper bracket 9, top 10, balance weight 11, clamping device 13, wherein clamping device 13 is by moving jaw 14, clamping device screw rod 15, and regular jaw 16 is formed.The big end of locking square bolt 1 is installed in crank T type groove 12 notches below, the base 3 of adjustment means is installed in locking square bolt 1 top, locking high nut 2 is fixed on the crank T type groove 12 by an adjustment means base 3 that is threaded with locking square bolt 1, base 3 connects by two lower carriages 4 and screw rod 8, two thrust bearings 6 are installed and to top locknut 7, screw rod 8 terminations are equipped with handle 5 at screw rod 8 one ends; Screw rod 8 tops connect by two upper brackets 9 and top 10, have a through hole on top 10, and regular jaw 16 belows of clamping device 13 have a through hole and are used for connecting with top 10, and touch mutually with balance weight 11 top 10.
In the real work, at first oil pumper is stopped according to the angle of balance, stop and tightly brake, deenergization, unload loose balance weight 11 fixed screws, lay down the balance weight lock dog, this adjustment means is placed on the crank face, its top 10 is touched mutually with balance weight 11, install and lock square bolt 1 below crank T type groove 12 notches, and with base 3 put into locking square bolt 1, buckle locking high nut 2 and tighten a base 3 and be fixed on the crank T type groove 12, turning handle 5 promotes balance weight 11 to desired location, finish the adjusting operation, as shown in Figure 1.When restriction owing to the space, when adjustment means promotion balance weight 11 can't be installed, need install clamping device 13 this moment on top 10, rotate clamping device screw rod 15, tighten clamping device 13 and clamp balance weight 11 and make its not slippage, the backward rotation handle 5 again, and pulling balance weight 11 is finished the adjusting operation to desired location.
