Abstract
The utility model relates to a lifting cage discharging door interlocking device using the moving state of a lifting cage to control the opening and the closing of a lifting cage discharging door. The driving end of the device controlling lever 6 of the utility model is hinged with the lower end of the vertical shaft of a rope expanding device fixedly connected with the lifting cage 9, the driven end of the device controlling lever and the driving end of an opening lever 3 are respectively hinged with the both ends of a connecting lever 5, and the end head of the driven end of the opening lever 3 is clamped in a slide box 2 fixedly connected with the lifting cage discharging door 1 and can be slid in the slide box. The utility model has simple structure, convenient installation, high durability and good safety without changing the structure of the original lifting cage when the lifting cage discharging door interlocking device is installed.
Description
The utility model relates to a kind ofly to be controlled by the moving state of hanging basket, no manual control, finish locking or open the control setup of hanging basket door, particularly a kind of interlock system of hanging basket discharge door.
But the general automatic switch of hanging basket feeding gate of the goods of selling in the market usefulness building hoist, and the discharging safety door has plenty of the simple and easy railing of employing, has plenty of the employing clamshell doors, have plenty of to adopt and pull door, be manual manipulation, require in all fail to be up to state standards (GB10055-88) " building hoist safety rule " and the Ministry of Construction's standard (JGJ88-92) " portal frame and derrick material elevator technical specification of security ": the switch of lifter safety door should adopt electric and mechanical interlocks.For reaching this requirement, manufacturer has carried out studying for a long period of time and has failed all the time to solve.
It is a kind of when elevator basket is done lifting and moved in order disclose that the purpose of this utility model is exactly, and its discharge door SELF CL is only when hanging basket stops layer shelving, Cai the hanging basket discharge door controller for opening and closing of discharging safety door self-opening.
The utility model is to adopt lever interlock principle to realize its goal of the invention, be a cover fulcrum respectively to be set be fixed on lever on the hanging basket near hanging basket top and hanging basket discharge door specifically, what be arranged on the hanging basket top is the control lever, its drive end be installed on the hanging basket, and the vertical shaft upper end is connected by the steel rope rope sling and the hanging basket master lifting rope of adjustable length, the vertical shaft lower end is provided with the vertical shaft lower end that a boss blocks the rope tensioning device that is placed in the outer compression spring of vertical shaft and is hinged, and the two ends of connecting rod are respectively with the Partner of control lever be arranged near the drive end hinge of the unlatching lever the hanging basket door; The fulcrum of opening lever is fixed on the other hanging basket of hanging basket discharge door, when running, its Partner termination do the plane circular motion owing to open lever, then the relative distance of its Partner termination and hanging basket door changes with motion, therefore open lever Partner termination and hanging basket discharge door for can slide relative being connected, can adopt and on the hanging basket door, open a strip shape draw-in groove, open the lever Partner and snap in the interior mode of draw-in groove, also Partner can be contained on the hanging basket discharge door with a U-shaped hinge hinge, but had better on the hanging basket discharge door, install a sliding box, the Partner of opening lever is placed in the sliding box, when hanging basket is done the lifting operation, hanging basket master lifting rope is stressed, the pulling force of main lifting rope makes the compression spring compression in the rope tensioning device, and the drive end that drives the control lever upwarps, this motion is delivered to through connecting rod and opens on the lever, and unlatching lever Partner is upwarped, and drives the hanging basket discharge door and upwards closes; Otherwise, when hanging basket stops layer when shelving, the lifting rope pulling force suddenly disappears, restoring force when then compression spring automatically resets will be controlled the lever drive end and press down, this motion is through connecting rod and open lever transmission, drives the hanging basket discharge door and does downward breakdown action, simultaneously, because the deadweight effect of hanging basket door, then can reach in the purpose of stopping layer hanging basket discharge door self-opening when shelving.
Because the utility model adopts the lever mode, so make this novel hanging basket discharge door interlock system structure very simple, easy for installation, need not change former barrel structure during installation, and this new device is durable in use, economical and practical.Because of this new device is not subjected to powerful traction in operational process, so safety performance is good, flexible operation is reliable.
Below in conjunction with accompanying drawing, preferred forms of the present utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the birds-eye view of Fig. 1;
In the present embodiment, the Partner that the drive end hinge is loaded on the control lever 6 of rope tensioning device 8 is provided with two forked forearms, and two forked forearms are connected by the cross bar that is positioned at fulcrum 7 places, and fulcrum 7 is packed on the hanging basket 9; Two connecting rods 5 that are symmetricly set on about the hanging basket discharge door are hinged with the drive end that the two forked forearms and two of control lever 6 are symmetricly set in the unlatching lever 3 of hanging basket discharge door 1 both sides respectively; The Partner of opening lever 3 is placed in two symmetries respectively and is installed in the sliding box 2 at two ends, hanging basket discharge door 1 left and right sides, can be provided with in the sliding box 2 one be positioned at open lever 3 plane of movement, notch is in the face of the plane deep-slotted chip breaker of unlatching lever 3 Partner; Sliding box 2 also can be designed to opening surface is enough to hold the draw-in groove shape of opening the slip of lever 3 Partner to the groove depth of opening lever 3, and the Partner termination of opening lever 3 is placed in the sliding box 2, and bar portion freedom puts in sliding box 2 notches and stretches out.
