Description
Technical field
The utility model relates to the field of electromechanical appliance steel rope clamping, especially a kind of two jaw clamping device for steel cable.
Background technology
Along with the development of skyscraper, elevator usage quantity gets 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 surveillance inspection procedure of State General Administration for Quality Supervision's appearance in 2002, require within every 2 years, should check once (consistent with the inspection procedure that 2009 revise) with the velocity limiter of elevator.And in the process of elevator governor field-checking, must in advance the steel rope of elevator governor be clamped, then slow speed operation elevator is separated steel rope from governor sheave, just can carry out inspection work below.
In addition, carry out rapid simulated test to elevator governor, can judge that can this velocity limiter action by fast qualitative, be the daily repair and maintenance of elevator and the important step of inspection.Carry out rapid simulated test to elevator governor, same needs first clamps the steel rope of elevator governor, and then slow speed operation elevator is separated steel rope from governor sheave, just can carry out rapid simulated test work below.
But, typically have a diameter from φ 8 or φ 6mm due to elevator speed limiter wire rope, market there is no suitable rope gripper at home.Be generally used in the locking pliers bought on the market, its jaw shapes difference is larger in the past.Clip site rope operating difficulties, needs to add shield at jaw, but still easily causes steel rope to be crushed, presss from both sides flat phenomenon; Sometimes also there is skidding unsafe condition, very unreliable.
Due to the harmless rope gripper that neither one on home market is perfect, the folder rop exercise detected at the scene needs to add some shields in order to avoid pressing from both sides flat wound rope in doing, but still very unreliable, and cause the unsafe condition of skidding sometimes, work efficiency is lower.Some Inspection Units even need the velocity limiter overall pulling down all elevators, and deliver to formulation place testing platform and detect, then transport go back to use scene and reinstall, work efficiency is very low, also delays elevator and uses.
In addition, because on machine room floor, the bore hole size of reeve differs, jaw support section size must be able to be adjusted, in order to avoid cause space interference or jaw bearing length deficiency, impact uses.
Summary of the invention
The purpose of this utility model is the two jaw clamping device for steel cables providing a kind of structure simple, easy to operate, safe and reliable.
As follows for reaching the technical solution that above-mentioned object adopts:
1. a two jaw clamping device for steel cable, original jaw improves, increase adjustable ball backing plate to support the use, it is characterized in that, described left binding clip is corresponding with right binding clip is provided with I circular arc jaw and II circular arc jaw, and described adjustable ball backing plate one end line of centers has U-shaped elongated slot and coordinates I circular arc jaw or II circular arc jaw to use.
2, the two jaw clamping device for steel cable of the one as described in technical scheme 1, wherein, described I circular arc jaw diameter is 6mm, II circular arc jaw diameter is 8mm.
3, the two jaw clamping device for steel cable of the one as described in technical scheme 1, wherein, described I circular arc jaw, II circular arc jaw and adjustable ball backing plate can make all size as required.
The utility model has following feature and advantage:
(1) this device forms 2 jaws by 2 specific circular arcs, can be used for the harmless clamping of steel rope of two kinds of different-diameters.Do not damage steel rope after its clamping, have auto-lock function; The size of its gripping power can regulate as required.
(2) this device has filled up the blank of home market wire rope nondestructive clamp device.
(3) this device solves the conventional difficulties of elevator governor field inspection process folder rope wound rope and skidding.
(4) this device supports the movable pad of jaw, can stretch out on the hole of the various different sizes being supported in floor steel rope, avoid space interference, make the position that clamping system energy secure support is being determined along caliper.
(5) through onsite application, this device is simple to operate, safe and reliable, substantially increases work efficiency, satisfactory for result.
(6) utilize this device, rapid simulated test can be carried out to elevator governor.Fast slack rope operation is carried out to elevator governor, be the periodical survey of elevator Inspection Unit, the self-inspection of elevator maintenance maintenance unit, greatly increase work efficiency, provide a great convenience.
(7) popularizing application prospect is wide, according to the data that State General Administration for Quality Supervision announces, by the end of the year 2013, domestic elevator quantity more than 300.93 ten thousand, and will to get more and more.
Accompanying drawing explanation
Fig. 1 is integral structure front view of the present utility model,
Fig. 2 is adjustable ball backing plate front view of the present utility model.
In Fig. 1 ~ Fig. 2, adjustable ball backing plate (1), I circular arc jaw (2), II circular arc jaw (3), left binding clip (4), right binding clip (5), U-shaped elongated slot (6).
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
With reference to shown in Fig. 1, Fig. 2, a kind of two jaw clamping device for steel cable, original jaw improves, increase adjustable ball backing plate to support the use, wherein, described left binding clip 4 is corresponding with right binding clip 5 is provided with I circular arc jaw 2 and II circular arc jaw 3, and described adjustable ball backing plate 1 one end line of centers has U-shaped elongated slot 6 and coordinates I circular arc jaw 2 or II circular arc jaw 3 to use.Described I circular arc jaw 2 diameter is 6mm, II circular arc jaw 3 diameter is 8mm.
Described I circular arc jaw 2, II circular arc jaw 3 and adjustable ball backing plate 1 can make all size as required.
Utilize this device to operate the clamping slack rope of elevator governor field inspection process: on machine room, on the hole limit to the up side of velocity limiter, this rope gripper is installed.The I circular arc jaw 2 corresponding to this device or II circular arc jaw 3 is selected according to the diameter of steel rope, as hole is greater than jaw, below rope gripper, the adjustable ball backing plate 1 laid and support jaw is then first stretched out along caliper direction, then speed limit steel rope is clamped, screw lock bolt, the up a bit of stroke of car crawl is made with inspection speed, just can carry out the rop exercise of separation steel wire very like a cork to do, by rope or waste leading wire section, speed limit rope is gently tied to side if desired, just (can note: during speed limit rope reset operation velocity limiter work of testing, for avoiding gang switch action below, the descending a bit of stroke of car crawl should be made, just rope gripper can be unclamped).
This device is applicable to the field of elevator governor field-checking, maintaining and rapid simulated test.Such as, before field-checking, analogue test are carried out to elevator governor, be separated the folder becket bridle joint of steel rope from velocity limiter.Also the other field relate to steel rope clamping, fixing and check.
