Definitions
- the invention relates to a construction hoist with one along a mast mobile platform, whose traction drive from one along a corner post of the mast running, with a pinion meshing rack and off a brake geared motor for the pinion, and with a function of the travel one with the braking torque of the Brake acted upon supporting spring adjustable contact piece for a circuit breaker the geared motor.
- the invention is therefore the object of a construction hoist the beginning outlined manner with an overload protection equip so that with a comparatively low construction costs conventional units of geared motor and brake can be used.
- the invention solves the task by the fact that the geared motor one of the pinion shaft interspersed support sleeve is flanged, the coaxial rotatably connected to the pinion shaft in a rotatably connected to the driving platform Bearing housing supports and is supported by the support spring on the bearing housing, between the gear motor and the switching piece and the overload switch are arranged.
- the derivative the braking torque is not done via the rotatably held motor housing, but on the rotatably held bearing housing for the support sleeve on the platform, which is due to the geared motor and the brake formed unit with the support sleeve opposite the bearing housing can twist the force of the support spring.
- the detail shown construction hoist according to the embodiment has a three-sided mast 1, of which three Eckstehern 2 two one Move guide for a driving platform 3 form, with the help of a traction drive 4 can be moved along this guide.
- a rack 5 which meshes with a pinion 6.
- the shaft 7 of this pinion 6 is as extended output shaft of a geared motor 8 is formed, which with a usual brake 9 is provided.
- the shaft 7 of the pinion 6 is corresponding to the Fig. 3 on the one hand in a flange 10 of the gear part 11 of the geared motor 8 and on the other hand mounted in a support sleeve 12, which itself in a bearing housing 13 is rotatably supported.
- This bearing housing 13 is via a mounting flange 14 screwed to the driving platform 3.
- the Support sleeve 12 On the transmission part 11th facing, axially over the bearing housing 13 vorrgenden front side is the Support sleeve 12 with a connecting flange 15 for the flange 10 of the bearing part 11 provided.
- the connecting flange 15 of the support sleeve 12 is like the mounting flange 14 of the bearing housing 13 radially beyond the bearing housing 13, so that at these flanges 14 and 15 against each other in the circumferential direction offset, axially against each other projecting support stops 16 and 17 attached between which a support spring 18 in the form of a Disk spring package can be supported.
- the support spring 18 is received by a guide pin 19, on the one hand the support stop 16 and on the other hand a guide approach 20 of the mounting flange 14 displaceably passes through.
- This guide pin 19 is provided with a thickened end portion 21 to which the Support spring 18 is an abutment, so that the thickened end portion 21 through the resting on the support stop 16 support spring 18 against the support stop 17th is pressed.
- the bias of the support spring 18 can thus via an adjusting nut 22 are set, which on a threaded portion of the guide pin 19 screw adjustable sits.
- the switching piece 24 is on a with the transmission part 11th connected fastening bolts 28 mounted screw adjustable, so that the for the operation of the overload switch 23 required travel of the geared motor 8 relative to the bearing housing 13 according to the respective conditions can be adjusted. Is at an overload of the driving platform 3 of Gear motor 8 to the shaft 7 of the pinion 6 in the dash-dotted lines in Fig. 1 indicated pivoting position pivoted so takes the contact piece 24 in the Fig. 4 dash-dotted drawn switching position, in which the shift lever 26th is swung against its spring load with the effect that the Studentslastschaqlter 23, the operation of the geared motor 8 locks.
