The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A mechanical ascending and descending inhibiting device, comprises jacking system and limit detection device.
As Fig. 1, shown in 2 and 3, described jacking system comprises lifting motor 1, drive the lifting shaft 2 being connected and the pulley assembly 3 being connected with lifting shaft 2 with lifting motor 1 mouth, described pulley assembly 3 comprises fixed pulley group 15 and running block 16, described fixed pulley group 15 drives and is connected with lifting shaft 2 mouths, described running block 16 is connected with lifting body frame 4 by lifting lacing wire 17, between described fixed pulley group 15 and running block 16, adopt steel cable 18 to be connected, described lifting motor 1 is fixedly installed on and is connected on quarter bend 5 by channel-section steel, described connection quarter bend 5 is connected with lifting support 6, the mouth of described lifting shaft 2 passes through antifriction-bearing box 19 and is connected quarter bend 5 connections.
One group of jacking system adopts a motor reducer as propulsion source, two lifting shaft transmission campaigns, this jacking system adopts pulley principle to realize lifting, and this device is convenient to equipment when cleaning, and lifting body frame is raised to certain altitude, then insert safety lever, device interior is cleaned; This device is main to be considered conveniently device interior to be cleaned and keeped in repair, and there will not be any corner or spot as yet untouched by a clean-up campaign.
As shown in Fig. 4-7, described limit detection device comprises the lifting shaft gear 7 being arranged on lifting shaft 2, the detection screw gear 8 meshing with lifting shaft gear 7 and the detection screw mandrel 9 being threaded with detection screw gear 8, at described detection screw mandrel 9 two ends, be provided with the check-out console corresponding with approach switch 10 11, on described detection screw mandrel 9, be provided with rotation preventive mechanism and make it under the effect that detects screw gear 8, along it, axially make traveling priority; Described rotation preventive mechanism comprise be arranged on the detection screw mandrel slotted eye 12 detecting on screw mandrel 9 and coordinate with described detection screw mandrel slotted eye 12 and with the detection screw mandrel slide assemblies 14 that is fixed on support quarter bend 13 connections that are connected on quarter bend 5.
When lifting shaft rotates under driven by motor, gear on lifting shaft rotates simultaneously and drives and detects the direction rotation in contrast of screw gear court, detect and on screw gear, to be processed with and the tapped bore that detects screw mandrel and coordinates installation, when therefore detection screw gear turns, detect screw mandrel also should rotate thereupon, but, owing to detecting screw mandrel, be at one end processed with one section of slotted eye, this slotted eye coordinates with detection screw mandrel slide assemblies, thereby screw mandrel cannot be rotated, can only sway, rotation is converted into displacement, making to detect screw gear rotation drives the circular movement that detects screw mandrel to become the straight-line motion that detects screw mandrel, detect screw mandrel two ends check-out console is installed, in detection relevant position, screw mandrel two ends, be provided with approach switch, when design, first design by the adjustable height of the most applicable production of jacking system, operation, then determine lifting motor model and rotating speed, during debugging according to the adjustment of displacement approach switch position of detecting screw mandrel, make to be risen to and be applicable to height by jacking system, and check-out console on detection screw mandrel just arrives approach switch position, lifting motor stops operating, and by jacking system, is stopped rising.
When jacking system rises, if detect screw mandrel, move right, while being risen to design height by jacking system, on detection screw mandrel, check-out console is to approach switch position, approach switch will be exported a signal to control system, and control system receives that sending a signal after signal stops motor again; When jacking system declines, detect screw mandrel to left movement, while being dropped to design attitude by jacking system, on detection screw mandrel, check-out console is to approach switch position, approach switch will be exported a signal to control system, and control system receives that sending a signal after signal stops motor again.
