Abstract
The utility model discloses a clamping pin-pulling device of a cable shield. The clamping pin-pulling device of the cable shield solves the problems that pin-pulling operation wastes labor and is unsafe in the prior art. The clamping pin-pulling device of the cable shield particularly comprises a pin-pulling mechanism and a pair of clamping pliers. The pin-pulling mechanism comprises a base, a supporting rod, an arc-shaped pressing rod and a pulling hook. A circular hole is formed in the center of the bottom of the base, the supporting rod is perpendicularly fixed to the base, the bent portion of the arc-shaped pressing rod is fixedly connected with the top of the supporting rod through a hinge pin, and one end of the arc-shaped pressing rod is fixedly connected with the pulling hook through a hinge pin; the head portion of the clamping pliers is provided with a pair of hooks bent inwards respectively, a connecting shaft of the clamping pliers protrudes out of a pliers body, threads are arranged on the protruding portion of the connecting shaft, the protruding portion of the connecting shaft is sleeved with the circular hole in the center of the base of the pin-pulling mechanism, and the pin-pulling mechanism and the clamping pliers are fixedly connected through the nut. The clamping pin-pulling device is simple in structure, easy to operate and capable of enabling operation to be easy through the lever principle, relieving the labor intensity of a worker and improving the operation efficiency of electric pump well detection.
Description
Technical field
The utility model relates to a kind of specific purpose tool of pulling pin.
Background technology
Electric immersible pump well is examined to pump, in playing oil pipe and cable process, during dismounting cable guard, common way is: the jaw that inserts guard shield both sides with clamping clip, guard shield is clamped, then screwdriver is inserted in the pinhole of guard shield, with spanner, upwards knock screwdriver handle, pin is pounded out, guard shield is removed.In unloading process, while knocking screwdriver handle with spanner, because of operating space too little, be very easy to pound sky, do not make strength, efficiency of construction is very low, sometimes also may pound in one's hands, even pin is pounded and is flown to hurt sb.'s feelings, so seem the operation of pulling pin of simple cable guard, but not light in real work, not only speed of application is slow, but also there is certain danger, have a strong impact on the efficiency of inspection pump.
Summary of the invention
The purpose of this utility model is to provide a kind of cable guard specific purpose tool of pulling pin, and use this instrument fast pin to be disassembled from cable guard, and disassembling section is laborsaving, unloading process safety.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cable guard clamps pin pulling out device, comprise pulling-out mechanism and clamping clip, described pulling-out mechanism, comprises base, pole, arc depression bar and pulls out hook, wherein the bottom centre of base arranges circular hole, pole is vertically fixed on base, the arc crook of arc depression bar and the top of pole are fixed together by bearing pin, and one end of arc depression bar is handle, and the other end is fixedly connected with and is pulled out hook by bearing pin; Described clamping clip, the head of pliers is the aduncate hook of a pair of difference, and the connecting axle of clamping clip protrudes from caliper, and the protuberance of connecting axle arranges screw thread, the circle hole sleeve at pulling-out mechanism base center, on the protuberance of connecting axle, and is fixed together pulling-out mechanism and clamping clip with nut.
The beneficial effects of the utility model: cable guard clamps pin pulling out device, simple in structure, lightweight, easy to operate, and the structure of the arc depression bar of design has been utilized lever principle, with clamping clip, clamp after guard shield, with pulling-out mechanism, can easily pin be extracted, very laborsaving, greatly alleviated workman's labour intensity, improved inspection electric pump well operation timeliness.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model cable guard clamps pulling-out mechanism in pin pulling out device.
Fig. 2 is the structural representation that the utility model cable guard clamps clamping clip in pin pulling out device.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Shown in Fig. 1 and Fig. 2: a kind of cable guard clamps pin pulling out device, comprise pulling-out mechanism and clamping clip 5, described pulling-out mechanism, comprise base 1, pole 2, arc depression bar 3 and pull out hook 4, wherein the bottom centre of base 1 arranges circular hole, and pole 2 is vertically fixed on base 1, and the arc crook of arc depression bar 3 and the top of pole 2 are fixed together by bearing pin, one end of arc depression bar 3 is handle, and the other end is fixedly connected with and is pulled out hook 4 by bearing pin; Described clamping clip 5, the head of pliers is the aduncate hook 7 of a pair of difference, the connecting axle 6 of clamping clip protrudes from caliper, the protuberance of connecting axle 6 arranges screw thread, the circle hole sleeve at pulling-out mechanism base center, on the protuberance of connecting axle 6, is then fixedly connected as integral body with nut by pulling-out mechanism and clamping clip.
During dismounting guard shield, first with two hooks 7 of clamping clip head, insert respectively the eyelet at guard shield two ends, then guard shield is clamped, and pulling out on the pin eye that hook 4 hangs over pin head pulling-out mechanism, firmly to the handle that presses down arc depression bar 3, owing to there being the support of pole 2, according to lever principle, the hook 4 that pulls out of arc depression bar 3 other ends is easily extracted pin from the pin-and-hole of guard shield docking section.
