Abstract
The utility model relates to a suspended rope protector for crushing load accidents of chain oil pumping unit rod columns. A box body is provided, suspended ropes penetrate through both ends of the box body, and the bottom ends of the suspended ropes are connected with both ends of a rope suspending device. A cam column is arranged in a through hole in the middle of the box body above the rope suspending device, and the cam column is hinged with two connecting rods. The connecting rods are hinged with two hinge rods whose ends are provided with suspended rope clamping hands, and the suspended ropes penetrate through the clamping hands. The utility model has the advantages that when a crushing load accident occurs, a cam drives the suspended rope clamping hands to tightly clamp the suspended ropes to avoid the accident of a transmission system, the braking is sensitive, and the operation is safe.
Description
The utility model belongs to a kind of protective equipment of oil well rig.
At present; in oil recovery process owing to multiple reasons such as holddown equipment fatigues; the disconnected accident of cutting of roofbolt appears; the disconnected back of carrying is owing to the counterweight imbalance; outstanding rope or rope hanger are rebounded in the pumping unit casing, make transmission system cause serious accident, though electrical appliance part can be protected; but, main transmission is done great damage because malfunctioning and inertia lags braking or is malfunctioning.
The purpose of this utility model is to overcome above-mentioned defective, can prevent effectively that outstanding rope from playing the protective gear of inlet body thereby provide a kind of.
The purpose of this utility model realizes in the following way:
This device comprises casing (1), the two ends of casing (1) have outstanding rope (2) to pass, outstanding rope bottom connects the two ends of rope hanger (3), wherein: the square box middle part has through hole on the rope hanger, have the cam post (4) of stretching out in the through hole, hinged two connecting rods of the part of cam post (4) in casing (5), hinged again two hinge-rods of connecting rod (5) (6), hinge-rod (6) end has outstanding rope clamp hand (7), outstanding rope clamp hand (7) is positioned at tank ends, be divided into inside and outside two-part, the centre is passed by outstanding rope, has the inclined-plane by casing part one side, contacts with the inclined-plane of vertical pusher (10), the other end of vertical pusher (10) also has the inclined-plane, contact with the inclined-plane of horizontal push (9) one ends, horizontal push (9) the other end also has the inclined-plane, contacts with push rod (8) on the cam post, push rod (8) both sides, top have the inclined-plane, respectively with about two horizontal push contact.
When the roofbolt crushing load accident occurring, outstanding rope (2) is being with upwards bounce-back of rope hanger (3), when pushing up cam post (4), move on the cam post, promotion level and vertical pusher move, promote to move in the outstanding rope clamp hand external lateral portion, push hinge-rod (6) to both sides simultaneously, it is tight that the inside and outside two-part of the outstanding rope clamp hand of promotion will hang rope clamp together.
The utlity model has following advantage: can prevent effectively that outstanding rope and rope hanger from entering the pumping unit casing, avoid the transmission system accident, braking is sensitive, and is safe and reliable.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation
Fig. 2 is that the A of Fig. 1 is to view
Fig. 3 is the outstanding rope clamp hand that is used for leaf chain
In Fig. 1: (1) casing; (2) outstanding rope; (3) rope hanger; (4) cam post; (5) connecting rod; (6) hinge-rod; (7) outstanding rope clamp hand; (8) lock hook.
Cam post has dragging track, and hinge-rod also has slide rail, makes its motion keep straight line, when outstanding rope is wire rope, adopts outstanding rope clamp hand shown in Figure 2, when outstanding rope then adopts outstanding rope clamp hand shown in Figure 3 for leaf chain.
Claims (1)
