Description
Technical field
The present invention relates to a kind of manipulator, particularly relate to a kind of safe anti-falling dropping control device of manipulator elevating mechanism.
Background technology
At present, when welding the large-diameter workpiece such as wind power tower drum, boiler, need welding gun to be raised to the top of workpiece, the maximum equipment of existing use is manipulator.After welding gun being risen to desired height by the elevating mechanism at manipulator top before welding, start welding job.But, elevating mechanism many employings chain form of manipulator or chain form on market; At present, domestic producer's many employings chain form, it does not possess falling proof device, there is larger potential safety hazard, once chain ruptures simultaneously, can cause great production accident; Part producer adopts the lifting form of chain transmission, and it is generally with the falling proof device of magnetite absorbent-type, but magnetite can weaken at situation magnetics such as shocks, vibrations, thus loses safe anti-falling and fall to acting on, and potential safety hazard is larger.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of manipulator elevating mechanism safe anti-falling dropping control device is provided, to solve the large problem of existing manipulator elevating mechanism potential safety hazard.
The object of the invention is to be achieved through the following technical solutions:
A kind of manipulator elevating mechanism safe anti-falling dropping control device, comprise the first support, second support and be arranged at the first support, fixed head between second support, described fixed head has notch, and be rotatably connected to ratchet by mandrel, described first support has blind hole in the horizontal direction, movably jacking block is provided with in described blind hole, spring is provided with between described jacking block and the bottom of blind hole, one end of described ratchet bottom is provided with the projection for blocking jacking block, the other end of ratchet bottom is provided with the lock pawl matched with ratchet, the top of ratchet is provided with mounting blocks, described mounting blocks has the installing hole for being connected with chain.
As preferred version of the present invention, described first support, the second support, fixed head are fixedly linked by screw.
As preferred version of the present invention, be provided with packing ring between the inwall of described ratchet and fixed head notch, described packing ring is Antirust washer; Ensure that ratchet and fixed head are contactless, while preventing from getting rusty, reduce frictional force when ratchet rotates, make ratchet operation more flexible.
As preferred version of the present invention, between the outer wall of described jacking block and the inwall of blind hole, be provided with copper sheathing, ensure that jacking block runs smooth and easy.
As preferred version of the present invention, described mandrel is made up of stainless steel material, and described jacking block is made up of stainless steel material; Bearing strength is large, ensureing that pawl device cannot can not work because getting rusty simultaneously, reducing potential potential safety hazard.
Beneficial effect of the present invention is, described manipulator elevating mechanism safe anti-falling dropping control device can effectively prevent because chain is aging or external force causes chain breakage, weight to occur from the accident fallen, the personal safety of effective guarantee device security and operating personnel, it is simple, compact that it has structure, flexible in operation, lock safe and reliable, durable in use, easy installation and removal is feature efficiently.
