Abstract
The invention relates to an anchor withdrawing device of a wire rope tester. The anchor withdrawing device comprises an anchor withdrawing ejection rod, a support plate and a side plate, wherein the anchor withdrawing ejection rod is fixedly provided with the support plate; the side plate is arranged on one side end surfaces of the anchor withdrawing ejection rod and the support plate, and the side plate is in a semi-ring shape. After an integral wire rope breaking force test is finished, the anchor withdrawing device is placed between jaw sheets of two jaw seats of the wire rope tester, the end part of the anchor withdrawing ejection rod is placed on the end surface of the jaw sheet on one end of the wire rope tester, the side plate is placed on the end surface of the jaw sheet on the other end of the wire rope tester, and the semi-ring-shaped part of the side plate is meshed with the section of a wire rope sample; when the wire rope tester is started, a hydraulic cylinder stretches out and draws back automatically, the two jaw seats of the wire rope tester generate interaction force with the anchor withdrawing device, and the anchor withdrawing ejection rod pushes the jaw sheet on one end of the wire rope tester to move, so that the jaw sheets are separated from a wire rope test sample alloy pouring head, and the jaw seats are opened. The anchor withdrawing device disclosed by the invention is easy, safe and convenient to operate and reduces the labor intensity of operators.
Description
Technical field
The present invention relates to method and device thereof that a kind of wire rope tester moves back anchor, belong to and detect rig for testing technical field.
Background technology
The mode that domestic breaking force of rope test machine clamping sample great majority adopt jaw seat to add jaw sheet is tested, and, for wire rope samples more than ∮ 30 mm, all adopt the method for cast alloys to carry out wire rope sample preparation.Because each rope strand in wire rope is helix shape, when wire rope bears certain load value, the tension and the rotating torque contrary with hand of helix that helix are extended generation, cause cast alloy sample head and jaw sheet to produce interaction force, and after test completes, alloy casting head is stuck on jaw sheet, jaw seat cannot be opened, must manually beat jaw sheet, just can open jaw seat and take out sample, operation labour intensity is large, and, there is again potential safety hazard in effort, time-consuming.
Summary of the invention
The method and the device thereof that provide a kind of wire rope tester to move back anchor are provided in order to overcome the deficiencies in the prior art.
The present invention utilizes this function of testing machine hydraulic cylinder automatic telescopic, in conjunction with wire rope, manufacture principle, the technology such as metal wire rod tension test principle and test method, the a set of wire rope of comprehensive Design moves back anchor special purpose device, after breaking force of rope test, by moving back anchor device, be placed between the jaw sheet of two jaw seats, utilize the interaction force producing by moving back anchor device between the action of testing machine hydraulic cylinder automatic telescopic and two jaw seats, make to produce the opposition in process of the test between jaw sheet and alloy casting head, thereby make jaw sheet separated with alloy casting head, realize opening of jaw seat.
Wire rope tester of the present invention moves back anchor device, and it forms by moving back anchor push rod, back up pad and side plate, moves back on anchor push rod and is fixedly installed back up pad, and side plate is arranged at a side end face of moving back anchor push rod and back up pad.Described back up pad is moved back anchor push rod for reinforcement and support.
Described side plate is semicircle annular, when semicircle annular and wire rope sample cross section tabling, guarantees steadiness when moving back anchor device uses, and this device is contacted well with jaw sheet.
Wire rope tester moves back the method for anchor, it is characterized in that by following implementation step:
(1) after overall breaking force of steel wire rope test, by moving back anchor device, be placed between the jaw sheet of two jaw seats of wire rope tester, moving back anchor push rod end is placed on the jaw sheet end face of testing machine one end, side plate is placed on testing machine other end jaw sheet end face, and the semicircle ring part of side plate and wire rope sample cross section tabling;
(2) starting characteristics test machine, make the action of hydraulic cylinder automatic telescopic, two jaw seats of testing machine produce interaction force with moving back anchor device, move back anchor push rod and promote the jaw sheet generation motion of testing machine one end, thereby make jaw sheet separated with wire rope sample alloy casting head, realize opening of jaw seat.
The present invention has jaw seat and opens conveniently, simple to operate, safety, and reduced operator's labour intensity, save again test period, and guaranteed safe operation.
Accompanying drawing explanation
Fig. 1 is that wire rope tester of the present invention moves back anchor device structural representation,
Fig. 2 is the left view of Fig. 1.
In figure: 1-move back anchor push rod, 2-back up pad, 3-side plate.
Embodiment

Described side plate 3 is semicircle annular, when semicircle annular and wire rope sample cross section tabling, guarantees steadiness when moving back anchor device uses, and this device is contacted well with jaw sheet.
Wire rope tester moves back the method for anchor, it is characterized in that by following implementation step:
(1) after overall breaking force of steel wire rope test, by moving back anchor device, be placed between the jaw sheet of two jaw seats of wire rope tester, moving back anchor push rod 1 end is placed on the jaw sheet end face of testing machine one end, side plate 3 is placed on testing machine other end jaw sheet end face, and the semicircle ring part of side plate 3 and wire rope sample cross section tabling;
(2) starting characteristics test machine, make the action of hydraulic cylinder automatic telescopic, two jaw seats of testing machine produce interaction force with moving back anchor device, move back anchor push rod 1 and promote the jaw sheet generation motion of testing machine one end, thereby make jaw sheet separated with wire rope sample alloy casting head, realize opening of jaw seat.
