Description
Technical field
The utility model relates to field of mechanical technique, particularly the motorless self-locking safety hooking device of mechanical parking library facilities.
Background technology
Three kinds of main fall arrest hooks that existing machinery formula garage parking hanging equipment hook device technology provides comprise:
1, electromagnetism sheet iron strip fall arrest hook: this is modal in the market a kind of.The weakness of this structure be after the electromagnet long-term action application life to electromagnet very big influence is arranged, and cost is higher, easy break-down.
2, mechanical type anti-fall off the hook: just use the fall arrest protection that pure mechanical device carries out sweep instead without electromagnet.The main feature of this mechanism is equipped with the fall arrest hook exactly on longeron; On sweep, installing can the device that struts hook related with chain or wire rope; Go up and down when linking up with the position when vehicle-containing like this; Device for spreading on the sweep contacts and removes hook with hook, thereby guarantees the normal up-down of vehicle-containing.At present because its structure relative complex, and when the drive motors brake was lost efficacy, can not play anti-drop function and used seldom.
3, portal frame: be a kind ofly to seem ugly, but a kind of anti-falling mechanism of insurance relatively.Promptly respectively install a portal frame made from square tube or pipe additional in the front and back of (3 layers and more than) on the side bar of all traversing sweeps or the traversing frame; Just in case when the chain of top sweep or wire cable rupture; The top sweep just directly falls on the portal frame below, to guarantee safety.This mechanism structure seems simply, but has increased equipment loading and energy loss, also influences outward appearance, thereby also limited use.
The utility model content
The utility model provides a kind of Stability Analysis of Structures, self-locking safety simple, that reliability is high to link up with.
To achieve these goals, the utility model provides following technical scheme:
A kind of self-locking safety hooking device, it comprises: hook and self-locking device,
Said hook comprises: hook bearing pin, coupler body and hook extension spring cover;
Said self-locking device comprises: alignment pin, self-lock rod, self-locking extension spring and self-locking bearing pin;
Said stopping means is an alignment pin;
Wherein: said coupler body is rotating to be installed on the said hook bearing pin; One end of said self-locking extension spring is fixed on the coupler body through hook extension spring cover, and the other end of said self-locking extension spring is connected with said self-lock rod interstitial hole position, and the self-locking bearing pin is installed in the centre of coupler body; Said self-lock rod is installed on the said self-locking bearing pin and rotates around said self-locking bearing pin; Said alignment pin is installed on the said coupler body, and is positioned at said self-locking bearing pin below, and is offside to lower swing with the restriction self-lock rod.
Through implementing above technical scheme, have following technique effect: the self-locking safety hook that the utility model provides, its Stability Analysis of Structures, member are simple relatively, reliability is high, energy-conservation, easy to implement and cost is lower.

The specific embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of self-locking safety hooking device, and is as shown in figures 1 and 3, comprising: hook 100 and self-locking device 200;
Said hook comprises: hook bearing pin 101, coupler body 102 and hook extension spring cover 103;
Said self-locking device comprises: alignment pin 201, self-lock rod 202, self-locking extension spring 203 and self-locking bearing pin 204;
Said stopping means is an alignment pin 201;
Wherein: said coupler body 102 rotating being installed on the said hook bearing pin 101; One end of said hook extension spring cover 103 is fixed on the coupler body 102; The other end of said hook extension spring cover 103 is connected with an end of said self-locking extension spring 203; Self-locking bearing pin 204 is installed in the centre of coupler body 102, and said self-lock rod 202 is installed on the said self-locking bearing pin 204 and rotates around said self-locking bearing pin 204, and alignment pin 201 is installed on the said coupler body 102; And be positioned at said self-locking bearing pin 204 belows, this alignment pin 201 is used to limit the angle that self-lock rod 202 rotates.The other end of self-locking extension spring 203 is connected the centre of said self-lock rod 202.
This hooking device is connected with hook Connection Block on the garage parking steel structure girder through hook bearing pin 101 to be fixed; Coupler body 102 can be around the center swing of hook bearing pin 101, and this hooking device centers on the center swing of hook bearing pin 101 under self-locking device 200 controls.
This self-locking device is connected with the bearing pin mode with hook, and limits its initial position with alignment pin.Perhaps break away from sweep with self-lock rod and self-locking extension spring teamwork control safety hook hook sweep during work.
The operating principle of this self-locking safety hooking device is: the energy (self-lock rod is lifted or compressed on sweep side bar top) that utilizes the garage parking sweep to rise; The self-locking device of this self-locking safety hooking device is put in place, padlock, hook get into the operating position, guarantee sweep with and on the passenger car parked be unlikely to because the unexpected fracture of chain and falling.Sweep with and on the passenger car parked need descend the time, earlier sweep is risen to and backs down self-lock rod and self-lock rod is being slipped under the pulling of self-locking extension spring under the plate of getting on the bus, at this moment, last sweep begins to break away from self-locking device restriction and decline.During decline, last sweep pushes self-lock rod downwards, thereby promotes whole hook part left side pendulum, rise out the space and let whole sweep descend smoothly.
More than a kind of self-locking safety hooking device that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
