Description
Technical field
It the utility model is related to a kind of machining tool, more particularly to a kind of flat mouth locking pliers of clamping.
Background technology
Existing TSG 7001-2009《Elevator surveillance is examined and periodic inspection rule --- traction and forcibly driving elevator》The
2.11 item requires：" service life reaches the elevator of 2 years, or abnormal, each regulator site envelope note of limiter of speed occurs in limiter of speed action
The elevator of damage, should carry out responsiveness school by licensed elevator inspection body or elevator production unit to limiter of speed
Test, and verification report is provided by the unit.”
In actual inspection work, mainly there are two kinds of square approach to test limiter of speed：User's censorship, scene inspection
Test.
User's censorship is carried out, it is convenient that inspector examines, but user needs to dismount limiter of speed, cumbersome, time-consuming, and
Elevator can only disable during this period, influence to use, and difficulty is brought to user.
Inspector can facilitate user to field test elevator governor.It is actual in the checkout procedure of limiter of speed at the scene
Used method is：Drive limiter of speed to rotate by stepless time adjustment electric drill, responsiveness is measured using revolution counter, so that simply
Quickly verify limiter of speed.But this test first has to allow speed limiter wire rope to depart from grooving, and allow elevator governor steel wire
Rope departs from grooving in most laborsaving, most highly effective and safe method, just to be solved the problems, such as into field test.
The method that currently used speed limiter wire rope is disengaged from the groove has following 3 kinds：
1 limiter of speed field stripping
Pit tensioning wheel is unloaded or padded, movable end speed limiter wire rope is securely fixed with rope card or other devices
In car top guardrail, fag end being torn open afterwards, being unreeved from limiter of speed, limiter of speed is verified at the scene.The method is imitated
Rate is low, takes time and effort, is dangerous larger, and accident easily occurs.This method is generally used for the verification of elevator speed limitor without machine room.
2 in the padded tensioning wheel of pit, progress speed limiter wire rope lifting
In the padded tensioning wheel of pit, speed limiter wire rope lifting is carried out, the human hand that the method needs is more, inconvenient, effect
Rate is relatively low, is generally rarely employed.
3 clamp speed limiter wire rope in computer room with locking pliers.
Carriage is unloaded, and carriage first is parked in 1m to 2m under the stop of upper end, limiter of speed is clamped with locking pliers on computer room floor
With the steel wire rope of pit tensioning wheel connecting pin, elevator will automatic pine with inspection speed uplink 400mm or so, speed limiter wire rope
Relax, stop elevator operation, disconnect main power source and Backup Power Switch, steel wire rope is departed from speed limit device wheel.
Under normal circumstances, this method verification personnel only need that in elevator(lift) machine room limiter of speed verifying work can be completed, and need
The people to be coordinated is few (usual two people just enough), and effortlessly, and it is shorter to remove the time of steel wire rope from limiter of speed, therefore is mesh
It is preceding using more method.But this method due to the use of clamping device be in the market purchase general locking pliers, although
This locking pliers easily crushes steel wire rope；Lived during actual clamping steel wire rope with cloth or other soft material pads, it is troublesome in poeration and
It is unreliable；And under the action of the downward pulling force of steel wire rope, locking pliers can be tilted or overturn.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of flat mouth locking pliers, which is set
There are the pad that can be used for locking pliers clamping, pad cloth used when locking pliers can be replaced to clamp, so that fast and easy
It is reliably achieved the clamping of steel wire rope.
The purpose of this utility model is realized by following technical solution：
A kind of flat mouth locking pliers, including：Upper tong arm, lower tong arm, the upper clamp nozzle of upper tong arm connection, the lower pincers of lower tong arm connection
Mouth and clamping pad；The head of the upper tong arm and the head of lower tong arm are hinged；Fluted, spiral shell is set on the clamping pad
Pit and circular groove；
The groove is arranged on the side of clamping pad, and is installed on flat mouth locking pliers by pad is clamped by the groove
Upper clamp nozzle and lower clamp nozzle on；
The threaded hole be opened in clamping pad top, and by the threaded hole will clamp pad be separately fixed at it is flat
On the upper clamp nozzle and lower clamp nozzle of mouth locking pliers；
The circular groove pads the medium position of flat horizontal surface positioned at clamping, for clamped wire rope.
Compared with prior art, one or more embodiments of the utility model can have the following advantages that：
(1) due to the effect of pad, the damage to steel wire rope is reduced.
(2) flat mouth locking pliers jaw is improved, respectively fills one piece of pad in two jaws, ensure locking pliers in experimentation
It will not be overturn because of movement.
(3) one action of clamping is only needed, avoids numerous and diverse program that tradition uses cloth, it is easy to operate.
(4) pad has higher friction coefficient, and rope cramp is next will not to produce slip again, reduces limiter of speed experiment
Time.

Pad 5；The head of the upper tong arm and the head of lower tong arm are hinged；Fluted 6, threaded hole 7 is set on the clamping pad
With circular groove 8；
The groove is arranged on the side of clamping pad, and is installed on flat mouth locking pliers by pad is clamped by the groove
Upper clamp nozzle and lower clamp nozzle on；
The threaded hole be opened in clamping pad top, and by the threaded hole will clamp pad be separately fixed at it is flat
On the upper clamp nozzle and lower clamp nozzle of mouth locking pliers；
The circular groove pads the medium position of flat horizontal surface positioned at clamping, for clamped wire rope.
Above-mentioned groove, can be such that clamping pad rides on jaw, be unlikely to move back and forth；Above-mentioned threaded hole, for that will serve as a contrast
Pad is secured firmly on flat mouth jaw；Above-mentioned circular groove, for limiting the movement of steel wire rope, suitable at present most of electricity
Terraced speed limiter wire rope.
The thickness of above-mentioned clamping pad is 5mm or so, has enough thickness, meets Structural strength calls, is unlikely to empress dowager
And hinder the clamping of steel wire rope.
A motion bar is provided between above-mentioned upper tong arm and lower tong arm, and is hinged by the motion bar, above-mentioned upper tong arm
