Abstract
The invention provides a double-jaw steel wire rope clamping device, and relates to the field of clamping of steel wire ropes of electromechanical devices. The double-jaw steel wire rope clamping device fills up blanks of the domestic market and is especially suitable for field inspection of elevator speed limiters and the rope clamping link in a maintenance process. The clamping device is characterized by comprising two jaws formed by two specific circular arcs, a locking plier body and a movable base plate accessory for supporting the jaws, and has the functions of not damaging the ropes, being capable of conducting self-locking type clamping and integrating two purposes in one pair of pliers, for example, the clamping device can be used for clamping two kinds of steel wire ropes which are commonly used for the elevator speed limiters and can be used for being supported against different floor slabs with holes, wherein the diameter of one of the two kinds of steel wire ropes is 6mm, and the diameter of the other kind of steel wire ropes is 8mm. One side of a steel wire rope of a speed limiter is clamped by the clamping device, the steel wire rope is supported against different edges with holes through a movable base plate stretching out along the plier body, space interference can be avoided, operation of an elevator is facilitated, and therefore the steel wire rope is separated from the speed limiter. According to the clamping device, the problems of rope damage and slipping in the rope clamping process are solved, operation is simplified, and work efficiency is improved. The clamping device is proved to be ideal in effect.
Description
Affiliated technical field
The present invention relates to the field that electromechanical appliance steel rope clamps, be particularly useful for the field of elevator governor field-checking, maintaining and rapid simulated test.For example, before elevator governor is carried out to field-checking, analogue test, the folder becket bridle of separated steel rope joint from velocity limiter; Also relate to the other field that steel rope clamps, fixes and check.
Background technology
Along with the development of skyscraper, elevator usage quantity is more and more.Elevator, as manned vertical transport equipment, once have an accident, can cause casualties.Therefore, China, in the eighties in last century, is just classified as " special equipment " and is carried out safety supervision management.In the elevator supervision and inspection rules of State General Administration for Quality Supervision's appearance in 2002, require within every 2 years, should check once at the velocity limiter with elevator (consistent with the inspection procedure of revision in 2009).And in the process of elevator governor field-checking, must in advance the steel rope of elevator governor be separated from governor sheave, take off rope and clamping steel wire rope, just can carry out check work below.
In addition, elevator governor being carried out to rapid simulated test, can judge that can this velocity limiter move by fast qualitative, is the daily repair and maintenance of elevator and the important step of check.Elevator governor is carried out to rapid simulated test, need equally first the steel rope of elevator governor to be separated from governor sheave, take off rope and clamping steel wire rope, just can carry out rapid simulated test work below.
Yet, due to elevator speed limiter wire rope typically have a diameter from φ 8 or φ 6mm, on market, there is no at home suitable rope gripper.Conventionally used the locking pliers of buying on the market, its jaw shape differs larger in the past.Clip site rope operating difficulties, need to add shield at jaw, but still easily causes steel rope to be crushed, press from both sides flat phenomenon; Sometimes the unsafe condition that also skids, very unreliable.
Due to the perfect harmless rope gripper of neither one on home market, the folder rop exercise detecting at the scene need to add some shields for fear of the flat wound rope of folder in doing, but still very unreliable, causes sometimes the unsafe condition skidding, and work efficiency is lower.Some check units even need the velocity limiter overall pulling down all elevators, deliver to formulation place testing platform and detect, and then transport go back to use scene and reinstall, and work efficiency is very low, also delays elevator and uses.
In addition, because the bore hole size of floor steel rope differs, jaw support section size must be able to be adjusted, so as not to cause space interference or jaw bearing length not enough, impact is used.
Summary of the invention
Object of the present invention: be for the indeterminable variety of problems of above-mentioned background technology, design a kind of pair of jaw clamping device for steel cable, apply at home.To solve folder rope slack rope operating difficulties, wound, restrict, skid, dangerous, unreliable, the problems such as inefficiency.
The present invention is achieved in that
Advantage of the present invention:
1, this device forms 2 jaws by 2 specific circular arcs, the harmless clamping of steel rope that can be used for two kinds of different-diameters.It does not damage steel rope after clamping, and has auto-lock function; The size of its gripping power can regulate as required.
2, this device has been filled up the blank of home market wire rope nondestructive clamp device.
3, the traditional difficult problem that this device has solved elevator governor field-checking process folder rope wound rope and skidded.
4, this device supports the movable pad of jaw, can stretch out on the hole of the various different sizes that are supported in floor steel rope along caliper, avoids space interference, makes clamping system energy secure support in definite position.
5, through scene, use, this device is simple to operate, safe and reliable, has greatly improved work efficiency, satisfactory for result.
6, utilize this device, can carry out rapid simulated test to elevator governor.Fast elevator governor is carried out to slack rope operation, for the periodical survey of elevator check unit, the self check of elevator maintenance maintenance unit, greatly increase work efficiency, provide a great convenience.
7, popularizing application prospect is wide.Only the elevator quantity in use surpasses 2,000,000, and more and more.
Accompanying drawing explanation
Fig. 1 is a kind of pair of jaw clamping device for steel cable.This application example, is the two jaw clamping device for steel cables for elevator governor check, is applicable to 2 kinds of clampings of setting specification wire rope.
Fig. 2 is the movable pad that supports jaw.(be 1 in Fig. 1, can eliminate the interference problem of different supporting and space.)
In figure, 1 for supporting a movable pad (steel plate that has U-lag of jaw, length can arrange as required, capable of regulating is laid, and jaw is supported on the hole of various different sizes of floor steel rope), 2 for diameter 6mm circular arc jaw, 3 for diameter 8mm circular arc jaw, 4 for left binding clip, 5 for moving caliper, 6 for pine pincers ripping bar, 7 for lock bolt, 8 for locking strut, 9 for spring, 10 for hinging pin shaft, 11 for fixed caliper, 12 be right binding clip.
The specific embodiment
Utilize the clamping slack rope operation of this device to elevator governor field-checking process: on machine room, on the hole limit of the up side of velocity limiter, this rope gripper is installed.According to the diameter of steel rope, select with this and install corresponding circular arc jaw (2) or (3), as hole is greater than jaw, first below rope gripper, along caliper direction, stretch out and lay the movable pad (1) that supports jaw, then clamp speed limit steel rope, screw lock bolt (7), with inspection speed, make the up a bit of stroke of car crawl, just can take off very like a cork rop exercise does, by rope or waste leading wire section, speed limit rope is gently tied to other if desired, just can to the velocity limiter work of testing, (note: during speed limit rope reset operation, for avoiding gang switch action below, should make the descending a bit of stroke of car crawl, just can unclamp rope gripper).
