Abstract

The invention relates to a special clamper, which comprises a clamper shell. The clamper shell is internally provided with two driving cams; the middle parts of the driving cams are connected with a driving shaft by splines; two ends of the driving shaft both pass through the clamper shell and are connected with a handle key; movable arm rotating wheels are respectively arranged at the inner sides of the two driving wheels; arc grooves of the movable arm rotating wheels are connected with the driving cams by dowel pins; the movable arm rotating wheels are connected with a clamper movable arm by power arms; the clamping movable arm is internally provided with magnets; ratchet movable blocks are arranged on the inner sides of the bottoms of the movable arm rotating wheels and connected with the movable arm rotating wheels by dowel pins; and ratchet lock blocks are clamped on the bottoms of the driving cams, and the middle parts of the top surfaces of the ratchet lock blocks prop against the bottoms of the ratchet movable blocks. The special clamper has the advantages that the operation is simple and convenient; a lock device is arranged to ensure that a camera device is firmly arranged without shaking, and cannot fall off due to the self inertia when a miner car is driven up and down or is emergently braked.

Description

A kind of dedicated workholder
Technical field
The present invention relates to a kind of dedicated workholder.
Background technology
The critical component that the inclined-drift rail winch road condition monitor is fixed on mine car the place ahead at random is dedicated workholder.The inclined gallery transportation will be seted out into hundred railway carriages hooking work per tour, and labour intensity is very large.This just require road condition monitor under pluck and upper extension very convenient, the weight of road condition monitor itself can not be too heavy.Simultaneously, onboard fixing of road condition monitor must be firm.Because the winch operation, in the startup of being everlasting, acceleration, moderating process, even has in the situation of brake hard, road condition monitor is subject to the inertia force influence of the winch speed of service (3.5 meter per second) and quality own.The railway carriage retaining part may have certain distortion in addition.Therefore, the car body dedicated workholder must adapt to above all situations and guarantee firm clamping.
Summary of the invention
The purpose of this invention is to provide a kind of dedicated workholder, circulate to overcome the inclined gallery winch at every turn, the workman must set out once, and transportation will be seted out into hundred railway carriages hooking work per tour, under the workman is frequent, plucks and upper extension, and labour intensity is very large; The inertia force of the quality of road condition monitor own simultaneously, also will solve that vehicle often starts in running, under the impact of acceleration, deceleration, brake hard inertia force, the fixing deficiency waited built on the sand of road condition monitor.
The objective of the invention is to be achieved through the following technical solutions:
A kind of dedicated workholder, comprise the clamper shell, the inside of clamper shell is provided with two driving cams, the middle part of driving cam is connected with power transmission shaft by spline, the two ends of power transmission shaft are all through the clamper shell and connect the handgrip key, the inboard of described two driving cams is equipped with the swing arm runner, arc groove on the swing arm runner is connected with driving cam by pin, the swing arm runner is connected with the clamper swing arm by power arm, magnet is equipped with in the inside of clamper swing arm, the bottom inside of described swing arm runner is provided with the ratchet motion block, the ratchet motion block is connected with the swing arm runner by pin, the bottom card of described driving cam has the ratchet lock dog, and the end face middle part of ratchet lock dog is resisted against the bottom of ratchet motion block.
Beneficial effect of the present invention is: simple, convenient, there is blocking device (adopting private key just can be operated) simultaneously, the operator will take off cam device, use private key to insert rotation one low-angle and just take off very easily, before camera is fixed on mine car by dedicated workholder, the visual angle broadness, clear picture, situation before car is presented in to drumman at the moment truly, guarantees the cam device arrangement firmly, do not rock.No matter mine car is up, descending, or brake hard all guarantees that cam device does not come off because of the inertia force of himself.

The specific embodiment
As shown in Fig. 1-6, the described a kind of dedicated workholder of the embodiment of the present invention, comprise clamper shell 1, the inside of clamper shell 1 is provided with two driving cams 2, the middle part of driving cam 2 is connected with power transmission shaft 3 by spline, the two ends of power transmission shaft 3 are all through clamper shell 1 and connect handgrip key 4, the inboard of described two driving cams 2 is equipped with swing arm runner 5, arc groove 6 on swing arm runner 5 is connected with driving cam 2 by pin 7, swing arm runner 5 is connected with clamper swing arm 9 by power arm 8, magnet is equipped with in the inside of clamper swing arm 9, the bottom inside of described swing arm runner 5 is provided with ratchet motion block 10, ratchet motion block 10 is connected with swing arm runner 5 by pin 11, the bottom card of described driving cam 2 has ratchet lock dog 12, and the end face middle part of ratchet lock dog 12 is resisted against the bottom of ratchet motion block 10.
During specific works, using the housing of monitor battery case as the quiet arm 13 of clamper, inboard studs with magnet piece, can be adsorbed on railway carriage.But clamper swing arm 9 idle rod runners 5 are done the rotation of 900 angles.The same small magnet piece of installing of clamper swing arm 9 front ends, can be adsorbed on railway carriage.Power arm 8 materials are spring steel, can produce certain clamp pressure.Swing arm runner 5 is by the driven rotary (pin 7 on driving cam 2 is stirred 3 rotations of swing arm runner) of driving cam 2.Driving cam 2 is fixed on power transmission shaft 3, the power transmission shaft 3 axle heads spindle nose that is square, and available square hole handgrip key 4 reverses.But on swing arm runner 3, separately have a pin 11 to insert in ratchet motion block 10, so the rotation of swing arm runner 5 is subject to again the constraint of ratchet motion block 10, ratchet motion block 10 motion left is subject to the prevention of ratchet lock dog 12 simultaneously.Therefore, once two jig arm are clamped is difficult to get loose voluntarily.
During upper extension, first with square hole handgrip key 4, the clamper swing arm 9 of dedicated workholder has been shaken, then the magnet piece on the quiet arm 13 of clamper is adsorbed on the railway carriage car body along the outside, then square hole handgrip key 4 rotates counterclockwise, two jig arm are pressed from both sides tighter and tighter, can take off square hole handgrip key 4 after clamping, due to the effect of ratchet lock dog 12, road condition monitor has been held pinning, can not get loose voluntarily; While taking off road condition monitor, plugging square hole handgrip key 4 clockwise rotates, the last stage cam of driving cam 2 rotations is first depressed ratchet lock dog 10, make the secondary disengagement of ratchet, two jig arm clamping forces are eliminated, when driving cam 2 continues rotation, when pin 7 drives swing arm runner 5 and power arm 8 half-twist angle, can easily unload road condition monitor.
