Description
Technical field
The utility model relates to a kind of press machine safety door protective system, relates in particular to the anti-chain rupture protective system of a kind of safety door.
Background technique
Safety door is the Safeguard of press machine, is installed between the column of press machine, and during press machine work, safety door is in full state, prevents that operator from entering the press machine working zone.When press machine more during mold exchange, safety door rises, and the shuttle table of press machine is driven into leave, more mold exchange.At this moment, operator also can come in and go out, and carry out some preparations or maintenance work.Safety door is not as there being safety protection device, and connecting because during unexpected the disconnection, safety door can fall rapidly between the lifting device of safety door and the safety door, very easily the operator to bottom cause personal injury.
Summary of the invention
The purpose of this utility model is exactly in order to solve at press machine unprotect device during mold exchange more; the easy problem that operator are damaged; provide a kind of and have simple in structurely, easy to use, can effectively play the anti-chain rupture protective system of safety door of safety protection effect.
For achieving the above object, the utility model adopts following technological scheme:
A kind of safety door is prevented the chain rupture protective system, and it comprises safety door, and described safety door is provided with the protective system of being made up of at least one retaining latch, upper saw pulley, suspension ring, wire rope, and wherein the retaining latch is welded on the safety door both sides; Suspension ring are installed on the safety door and with the lifting device of safety door and connect; Upper saw pulley is installed in the both sides of suspension ring; Wire rope one end connects with the retaining latch, and other has an end to connect with suspension ring.
Described retaining latch has housing, and at least one bayonet lock is installed in it, pocketed springs on the bayonet lock, and the bayonet lock end is provided with arm-tie, and arm-tie connects with wire rope one end.
Described upper saw pulley comprises support, and bearing is installed on the support, and roller is installed on the bearing.
Described suspension ring comprise suspension hook, and its two ends are provided with adjusting screw rod, and adjusting screw rod connects with the wire rope the other end, and the bottom of adjusting screw rod connects firmly welding block, and welding block is welded on the safety door, are the welding block spring in the welding block bottom.
The anti-chain rupture protective system of safety door of the present utility model is made up of safety door, retaining latch, upper saw pulley, suspension ring, wire rope etc.The retaining latch is made up of spring, bayonet lock, housing, arm-tie etc.; Upper saw pulley is made up of roller, bearing, support etc.; Suspension ring mainly are made up of suspension hook, welding block, spring, adjusting screw rod etc.
During use, the retaining latch is welded on the safety door both sides; Suspension ring are installed on the safety door, and the suspension hook on the suspension ring connects with the lifting device of safety door, and welding block is welded on the safety door; Upper saw pulley is installed in the both sides of suspension ring; Wire rope one end connects with arm-tie on the retaining latch, and the other end connects with adjusting screw rod on the suspension ring.
Under the normal condition, under the action of gravity of safety door, the bayonet lock on the retaining latch is contracted in the housing, and safety door can freely move up and down under the effect of lifting device.When accident takes place, disconnect such as the connection between lifting device and the safety door, bayonet lock ejects rapidly under the effect of spring, is stuck in the draw-in groove in safety door two side rails, and safety door is stopped rapidly, prevents personal injury.
On the safety door two retaining latches can be installed, have two bayonet locks on the retaining latch at least, as long as there is a bayonet lock to eject, safety door is stopped, safety coefficient is high.
The maximum protection weight of traditional protection device generally is no more than 200 kilograms, and Applicable scope is little; We can design the diameter and the number of bayonet lock according to the weight of safety door, can protect the safety door of various weight, and are applied widely.
The beneficial effects of the utility model are:
1, safety coefficient height can be avoided the generation of personal safety accident fully.
2, applied widely, can protect various safety doors.
