Further, the utility model provides a kind of emergency braking device, can also have such feature: elastic component is arranged on outside insulation sleeve.

Further, the utility model provides a kind of emergency braking device, can also have such feature: elastic component is fixed on hook fixing plate, and gapped between pressure guard.

Further, the utility model provides a kind of emergency braking device, can also have such feature: elastic component is arranged on pressure guard, and gapped between hook fixing plate.

Further, the utility model provides a kind of emergency braking device, can also have such feature: elastic component is evenly distributed on pressure guard.

The beneficial effect of utility model

A kind of emergency braking device being arranged in whole handling system providing according to the utility model, according to the controller common with whole handling system, the relay being communicated with controller signals, respectively and the hook fixing plate of relay conducting and pressure guard, be arranged on the elastic component conducting electricity between pressure guard and hook fixing plate, when pressure guard is subject to power upwards, elastic component contacts pressure guard and hook fixing plate simultaneously, relay sends signal, and it is out of service that controller is controlled whole handling system.So, in whole handling system operational process, because electric or mechanical breakdown cause the phenomenon that hook cannot hook basket or cleaned the improper disengaging hook of basket, and shock pressure guard, emergency braking device can stop the operation of whole handling system in time, has prevented mechanical arm pressure basket, badly damaged mechanical arm, clean the appearance of the phenomenons such as basket and cell body, ensured the safety and stability of normal production, avoided unnecessary economic loss.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Fig. 1 is the structural representation of whole handling system.

As shown in Figure 1, emergency braking device is arranged in whole handling system, and whole handling system controls lifting motor 20 by controller and cylinder 30 drives whole handling system to carry out work.

Fig. 2 is the structural representation of emergency braking device front view.

Emergency braking device comprises the controller common with whole shutdown feature, relay, hook fixing plate 2, pressure guard 1, six springs 3, six screw assemblies 4.

Controller is communicated with relay circuit, the signal of receiving relay.When relay sends signal, lifting motor 20 and cylinder 30 that controller is just controlled in whole handling system are out of service, make the work of whole handling system emergent stopping.

One end conducting of hook fixing plate 2 and relay, selects the copper material with excellent conductive performance.Some hooks 50 minutes two rows be distributed on hook fixing plate 2 symmetrically.

Pressure guard 1 is suspended on the below of hook fixing plate 2 by six screw assemblies 4.The below of the central axis position of pressure guard 1 in hook fixing plate 2.Six screw assembly 4 equidistant from distance are arranged, and evenly pressure guard 1 are suspended on to the below of hook fixing plate 2.Pressure guard 1 is selected the copper material with excellent conductive performance, with the other end conducting of relay.

When hook fixing plate 2 and pressure guard 1 conducting, relay circuit is communicated with, and will send signal to controller.

Tu4Wei emergency braking device Ministry of worker enlarged drawing.

As shown in Figure 4, screw assembly 4 comprises screw 4-1 and insulation sleeve.Insulation sleeve is comprised of column type insulating part 4-2,4-3 and the 4-4 of three hollows respectively.Insulation sleeve also can be made integrative-structure, mainly plays and prevents between pressure guard 1 and hook fixing plate 2 by screw conducting.

Screw 4-1 first passes three insulating parts, then through the hole on pressure guard 1, then overlaps upper spring 3, and last lemon is in the tapped bore of hook fixing plate 2.

Screw assembly 4 also can only be selected the screw of insulation material, does not need insulation sleeve.The screw of employing insulation material is subject to the restriction of material, and fixing intensity is less than the conductive material of metal, so can only adopt in the situation that screw holding capacity is less.

As shown in Figure 4, spring 3 is enclosed within outside insulating part 4-4, and the height of spring 3 is lower than the height of insulating part 4-4.End face of spring 3 and pressure guard 1 laminating arrange, and between another end face and hook fixing plate 2, have certain gap.Spring 3, as contact element, is selected the copper material with excellent conductive performance.

When pressure guard 1 is subject to impact, pressure guard 1 and spring 3 be upward movement together, when spring 3 touches hook fixing plate 2, and pressure guard 1 and hook fixing plate 2 conductings.

In addition, spring 3 can be welded on hook fixing plate 2, and has certain gap with pressure guard 1.When pressure guard 1 is subject to impact, pressure guard 1 upward movement, touches the spring being fixed on hook fixing plate 2, by pressure guard 1 and hook fixing plate 2 conductings.

Spring 3 also can adopt individually and be fixed on equably on pressure guard 1 or hook fixing plate 2, and is not arranged on insulation sleeve.

The working process of emergency braking device:

Cannot hook basket or clean the improper disengaging hook of basket when hook, clean basket and drop in process and can collision be suspended on the pressure guard on hook fixing plate.After pressure guard is clashed into, stressed moving up, spring contacts with hook fixing plate with pressure guard simultaneously, realize the conducting of pressure guard and hook fixing plate, it is turn-on relay circuit, relay will send signal to controller, and lifting motor and cylinder that controller is just controlled in whole handling system are out of service, makes the work of whole handling system emergent stopping.
