Description
Technical field:
The utility model is a kind of safety cover plate that is used for hole for hoist.
Background technology:
In the large-sized workshop of multilayer, all there are some to be used for the hole for hoist of hoisting object between the levels, these holes for hoist are not in that the time spent covers with cover plate, time spent is removed cover plate, and be provided with safety barrier around the hole for hoist, some guardrail is temporarily put, and is insecure, brought many potential safety hazards to operating personnel.Some cover plate is divided into two parts and is fixed on the hole for hoist both sides with the hinge axle, and when opening such cover plate, operating personnel must operate repeatedly can finish the process of opening cover plate, has brought inconvenience to operating personnel.
The utility model content:
The purpose that the utility model proposes is exactly for solving the problem that above-mentioned hole for hoist cover plate does not have safety barrier or cover plate can not interlock to open.The utility model is to address these problems the technical scheme that is adopted to be: head sprocket is fixed on both ends of main drive shaft, after being fixed on main cover plate on the driving shaft again, both ends of main drive shaft is packed in the main bearing seat and main step at steel framework two ends, to be separately fixed at the driven shaft two ends from sprocket wheel, driven shaft is fixing again being fixed on from cover plate, then the driven shaft two ends reinstall on the steel framework two ends from bearing support with from step; Main counterweight is fixed on the main counter-jib, be affixed to the master gear bottom again, from counterweight by being fixed to from counter-jib from the gear bottom, be separately fixed at main axis and from axis master gear with from gear, main axis and from the axis fixing respectively main middle sprocket and from middle sprocket, the main bottom bracket of more main axis being packed into respectively then, from axis is packed middle bearing block into; With the main chain bar head sprocket and main middle sprocket are connected, with from chain will from middle sprocket with connect from sprocket wheel, master gear with from gears engaged together, but and synchronous backward rotate, be provided with rotating guardrail down at the inboard end of main cover plate, from cover plate an inboard end be provided with rotating on guardrail; Main lower gear, main bottom bracket down, be consistent with above-mentioned installation site and mode from bottom bracket down, from lower gear and main counter-jib, from counter-jib, main counterweight, from counterweight.
The utility model course of work is: in the time of will covering in the vertical-horizontal position when main cover plate with from cover plate, main cover plate turns clockwise, head sprocket drives the main chain bar and drives main middle sprocket rotation, thereby driving master gear rotates, master gear also clockwise rotates main counterweight by main counter-jib, thereby offset most of weight of main cover plate, two main counterweight weight sums are less than main cover plate weight; Weight from the weight of cover plate and two from counterweight and equilibrium relation also be like this; Close in the closed procedure at main cover plate, master gear rotates counterclockwise with making from gear from gears engaged, thereby also rotates counterclockwise from cover plate by driving from axis, from middle sprocket, from chain, from sprocket wheel and driven shaft, with main cover plate close synchronously.Before master and slave cover plate will be closed, need with on U type bolt and following U type bolt extract, will go up the guardrail rotational fixation from the cover plate inboard, will descend the guardrail rotational fixation in main cover plate inboard.
When opening the hole for hoist cover plate, as long as two very heavy master and slave cover plates can be opened simultaneously by handle, open the back upper and lower guardrail of rotation and after master and slave cover plate is vertical, be fixed with upper and lower U type bolt with the power of 2～5kg, can bring into use.
The utility model design is ingenious, simple, safe and reliable, is convenient to produce, and be the desirable hole for hoist cover plate of multilayer factory, and the technical scheme that this utility model proposed also can open and close in electronic realization.
