Technical field
Cage was gone along with sb. to guard him door, cage door interlock switch device at the bottom of the utility model provided a kind of building hoist, belonged to the building hoist appurtenances.
Background technology
Building hoist must dispose end cage door and cage door, and its operation has following characteristics: cage promotes back end cage door, the cage door must be closed, and must not open before the cage landing, does not allow the unlatching that causes because of misoperation to occur in order to avoid cause danger.End cage door that building hoist adopted in the past and cage door operating gear rely on the electrical equipment measure to guarantee not opened by mistake the pass merely, are insecure through facts have proved, and need workmen's M/C to open or close, and the big idle work of work capacity is many.No locking measure safety was unreliable after end cage door was closed, and the cage door needs manual control switch's work capacity big.
The utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: provide a kind of and control conveniently, cage is gone along with sb. to guard him door, cage door interlock switch device at the bottom of the building hoist of saving manpower.
Cage is gone along with sb. to guard him door, cage door interlock switch device at the bottom of the building hoist described in the utility model, comprise near the cage that is provided with and go along with sb. to guard him frame, cage is provided with the cage door, go along with sb. to guard him to set up to be equipped with and go along with sb. to guard him door, it is characterized in that described cage door is provided with fixed mount, axle is turned in the fixed mount setting, it is hinged with fixed mount to turn axle, the described frame of going along with sb. to guard him is provided with position-limited rack, position-limited rack top is provided with connecting lever and the corner block that is fixed together, connecting lever and position-limited rack are hinged, and the connecting lever end is fixed on by extension spring and goes along with sb. to guard him on the frame, and the connecting lever top is arranged on turns the axle below.
When cage rose, the cage door began to glide with respect to cage at the effect lower edge track of deadweight, turned axle and rotated back to and drop down onto close stance, the connecting lever of going along with sb. to guard him on the frame loses the pressure that turns axle, up under the drive of extension spring, corner block rotates to and goes along with sb. to guard him a top simultaneously, and prevention is gone along with sb. to guard him door and opened.
When cage descended, the connecting lever of going along with sb. to guard him frame was oppressed in the axle decline collision of turning of cage door, under the exerting pressure of cage door gravity, turns axle from going to open position then, oppresses connecting lever simultaneously and rotates, and drives corner block and rotates to open position, and maintenance door can be opened.Cage continue to descend, and this moment, connecting lever stopped action under the effect of position-limited rack, and forces and turn axle and drive a cage door and rise with respect to cage, bottom cage drops to, and complete opening cage door.
As prioritization scheme, described fixed mount is provided with stop collar, and stop collar limits the hunting range that turns axle.Can prevent to turn axle and break away from the connecting lever top, cause the accident.
As prioritization scheme, described extension spring one end captive joint connecting lever end, the other end is gone along with sb. to guard him frame by the support captive joint.Convenient fixedly extension spring, and extension spring is easy to stressed.
As prioritization scheme, described cage is provided with baffle plate, baffle plate with turn the axle adapt.Turn after axle breaks away from connecting lever, baffle plate can be so that turn spool a maintenance level or a certain angle, so that cage turns the axle action that matches with connecting lever when falling once more.
Cage is gone along with sb. to guard him door at the bottom of the utility model building hoist, the beneficial effect that cage door interlock switch device is had is: by the cage door and go along with sb. to guard him frame be provided with respectively cooperatively interact the action turn the axle and connecting lever, make and under cage leaves the situation of bottom stop bit, turn axle and the cage door is gone along with sb. to guard him and closed to connecting lever teamwork meeting automatic blocking, prevent that staff's mistake from banging into interior the opening by mistake with the cage door of end cage and opening the danger that causes, and under the situation of cage whereabouts, turn axle and connecting lever teamwork, automatically open the cage door, open the spacing corner block of maintenance door, make things convenient for the workman to pass in and out and portage.
Description of drawings
Fig. 1 is the structural representation after the utility model embodiment cage lands.
Fig. 2 is the structural representation after the utility model embodiment cage draws high.
Among the figure: 1, fixed mount 2, turn axle 3, cage door 4, connecting lever 5, position-limited rack 6, rotating shaft 7, corner block 8, extension spring 9, support 10, go along with sb. to guard him door 11, safeguard frame 12, cage 13, baffle plate 14, stop collar.
The specific embodiment
Below in conjunction with the embodiment accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, lower railway and go along with sb. to guard him frame 11 on the cage 12 of building hoist near setting, fixed mount 1 is welded on cage door 3 sides, position-limited rack 5 is welded on the top of going along with sb. to guard him door 10 frame sides, going along with sb. to guard him door 10 is arranged on and goes along with sb. to guard him on the frame 11, fixed mount 1 is provided with and turns axle 2, it is hinged with fixed mount 1 to turn axle 2, position-limited rack 5 tops are provided with connecting lever 4 and the corner block 7 that is fixed together, connecting lever 4 is hinged by rotating shaft 6 and position-limited rack 5, connecting lever 4 ends are fixed on by extension spring 8 and support 9 and go along with sb. to guard him on the frame 11, and stretch out at connecting lever 4 tops, and are arranged on 2 below of turning of cage door 3.
Fixed mount 1 is provided with stop collar 14, and stop collar 14 limits the hunting range that turns axle 2.Cage 12 is provided with baffle plate 13, and baffle plate 13 adapts with turning axle 2, turns after axle 2 breaks away from connecting levers 4, and baffle plate 13 can be so that turn axle 2 a maintenance level or certain angles, so that cage 12 turns axle 2 action that matches with connecting lever 4 when falling once more.
The cage track that the utility model is mentioned, cage traction is common prior art, its connection and use to industry technical personnel and grasped.
Principle of work and process:
Initial ready position: 10 energy of maintenance door freely rise and fall, and cage door 2 is in opening.
When cage 12 rose, cage door 2 began to glide with respect to cage 12 at the effect lower edge of self gravitation track, along with cage 12 continue to rise to stop bit, turn axle 2 and fall after rise and rotate to baffle plate 13 close stances.Connecting lever 4 loses pressure, rotates under the effect of extension spring 8, rotates to up to corner block 7 and goes along with sb. to guard him door 10 tops, and prevention is gone along with sb. to guard him door 10 and opened.Cage door 3 was locked under the effect of stop collar 14 and can't opens in the high-altitude this moment.
When cage 12 descends, the connecting lever 4 of going along with sb. to guard him frame 11 is oppressed in axle 2 collisions of turning of cage door 3, cage door gravity exerting pressure under, turn axle 2 from going to open position, finally under the effect of stop collar 14, stop operating, oppress connecting lever 4 rotations simultaneously, drive corner block 7 and rotate to open position, go along with sb. to guard him door 10 and can open.Cage 12 continues to descend, and this moment, connecting lever 4 stopped action under the effect of position-limited rack 5, and forces and turn axle 2 and drive cage doors 3 and rise with respect to cage 12, bottom cage 12 drops to, and complete opening cage door 3.
