By adopting the crane operating handle safety management device, the crane operating handle can be completely protected in an encircling manner, so that the electrical equipment in the crane operating handle can be effectively isolated from the peripheral environment, the harm of the peripheral environment to the crane operating handle can be prevented and the normal application of equipment can be ensured.
Description
Technical field
The invention belongs to the accessory appliances about hoisting crane in pumped storage technical field, be specifically related to a kind of operating handle of crane security control apparatus.
Background technology
Hoisting crane belongs to the special equipment of national regulation, because mechanism's complexity, load are changeable, huge structure, dangerous large, its operation, uses and manages and all have strict administrative provisions.Precious spring hydroenergy storage station in headstock gear building, upper storehouse, headstock gear building, lower storehouse, ground G IS chamber be provided with 5 hoisting cranes, the installation and maintenance that are mainly headstock gear equipment, GIS equipment are used; Crane operation all adopts cable attended operation handle, is furnished with source switch and each action button on this handle, completes that rising, decline, cart to crane hook moves forward and backward, the operation of cucurbit sway; Only exposed placement of this operating handle before; environment of living in is comparatively severe; moist in building; dewfall phenomenon is serious, and long-time electric elements is fragile, causes breakdown of equipment to use; and this handle is not installed additional to any fender guard; there is irrelevant operating personnel's contrary to regulations, go on duty without relative certificate, cause serious special equipment accident risk.
Summary of the invention
The present invention is in conjunction with above phenomenon, and we have designed a set of special security control apparatus for operating handle of crane amount body, and this device is fixed on around operating handle, and operating handle has been played to good protection, faulty action preventing protective effect.
The solution of the present invention: a kind of operating handle of crane security control apparatus, shell and protecgulum are installed together by hinge, and are provided with lockset; The operating handle of Matching installation hoisting crane in shell, shell upper is provided with cable fluting; On the side of shell or described protecgulum, be provided with the resigning hole corresponding with controlling button on operating handle; Between the upper end of operating handle and outer casing inner wall, spring is installed, suspension ring that stretch out shell are set in operating handle upper end simultaneously, meet: in the time that suspension ring are draped, shell is down sliding under Gravitative Loads, and control button and the corresponding resigning hole of operating handle stagger; In the time that suspension ring come off suspension, under action of the spring, the control button of operating handle aligns with corresponding resigning hole.
In fact, for the control button that makes operating handle can stretch out outside resigning hole in the time normally using, and in indentation resigning hole, stash again while not using, can adopt following structure: be provided with low wide and up narrow inclined plane slide block at the leading flank of operating handle, wall or protecgulum inwall relevant position are provided with the up-narrow and down-wide inclined plane groove of coupling in the enclosure, and described inclined plane slide block can coordinate with inclined plane groove slip.Thereby, in the time that suspension ring are suspended, operating handle under the cooperation of inclined plane slide block and inclined plane groove, the movement that slopes inwardly, the each control button originally stretching out outside resigning hole moves up and reaches concealment effect after indentation resigning hole.
Above scheme, can, by a gasket ring that is sleeved on operating handle of crane upside is set, shell be applicable to the operating handle of all hoisting cranes, cable mount pad is drawn from the mesopore of gasket ring, the upside of gasket ring is provided with spring perch mounting spring, and the spring other end is connected with outer casing inner wall.The structure that gasket ring carries spring goes for the operating handle of multiple hoisting crane.Gasket ring one side can be arranged to opening, so that allow cable pass after this opening, gasket ring is sleeved on to cable mount pad outside.
Beneficial effect of the present invention:
1, this security control apparatus completely surrounds operating handle of crane to protect, and can actv. be isolated by internal electric equipment and surrounding environment, prevents from, because of the infringement of surrounding environment to operating handle of crane, causing equipment normally to use.
2, this safety device is fixed on wall nearby, realizes the fixationization management of operating handle.
3, this security control apparatus additionally installs lockset additional, realize operating personal can control crane operation, in control, avoid because the personnel without job that requires special skills operation card are not in the situation that understanding field operation step, this handle of maloperation and special equipment personal casualty, device damage accident occur, effectively improves the safety management requirement of applying unit to special equipment.
