Specific embodiment
Below in conjunction with Figure of description, the invention will be described in further detail, and provides specific embodiment.
As shown in Figure 1-3, a kind of car machinery prevents device, which is applied to low top layer and shallow pit
Elevator, for example elevator and household ladder are installed additional when carriage or counterweight are fully pressed against on buffer, top layer and bottom minimum space are not
The problem of foot, while guaranteeing safety of the maintenance staff in maintenance and checking process.Its structure specifically include bottom plate, fixed column,
Torsional spring, rotation stopping part, rotation stopping part are connect by connecting column with fixed column, and the lower end of connecting column and the top of fixed column are solid
Fixed connection, the upper end of connecting column are pierced by swing arm, and socket is provided with torsional spring on connecting column, and the other end and rotation stopping part of torsional spring are solid
Fixed connection, the rotation stopping part include the swing arm and the elastomer block being arranged on swing arm both ends that a section is square, and the one of torsional spring
End is fixedly connected with swing arm；The top of fixed column is additionally provided with electromagnet and limit switch assembly, and electromagnet passes through conducting wire and sets
The microswitch electrical connection at layer door lock is set, limit switch assembly concatenation is arranged in electrical safety return circuit, and limit is opened
Closing component includes elevator run switch and overhauling elevator switch, and elevator run switch and overhauling elevator switch are set in an angle of 90 degrees
It sets.To realize the limit rotated to swing arm, baffle, baffle are additionally provided at the position of overhauling elevator switch in fixed column
Extend up to the middle position of swing arm height.
As shown in figure 4, it further includes that upper limit switch electric loop is arranged in hoistway that the car machinery, which prevents device, on this
Limit switch electric loop includes that the magnetic stripe being arranged in hoistway on car guide rail and the monostable magnetic being mounted on Knapsack-rack are opened
It closes, in overhauling elevator uplink, after magnetic switch enters the induction region of magnetic stripe, elevator stops upward inspection travel, at this point, can only
Overhaul downlink.
The present invention is installed on well pit by one rotatable mechanical stopping device of design, the mechanical stopping device,
When off-position, as seen in figs. 5-6, rotatable stop is parallel to sedan-chair frame and counterweight；When operating position, as Figure 7-8,
Rotatable stop is located at elevator car frame buffer board and counterweight perpendicular to sedan-chair frame and counterweight, the elastomer block of swing arm both ends setting
The lower section of frame buffer board, this mechanical stopping device are both upper mechanical preventing device and lower mechanical preventing device, meanwhile, in order to
It is convenient to be resetted outside hoistway, meet standard requirements, which is mounted on shaft bottom at layer door position.
The microswitch being mounted at layer door lock, when opening layer door lock by triangulation chain, by microswitch and machinery
