Abstract

The utility model relates to a shockproof lighting lamp for mining machinery, which is suitable for occasions with strong shock, and is especially suitable for large machines in a mine, such as excavation. The lighting lamp is composed of a guarding lamp cover, a transparent cover, a reflector, a lamp bulb, a lamp holder, a device for damping shock, a transformer and a trigger, wherein, the device for damping shock is composed of dampers, damping springs, a fixed ring and a bracket, wherein, the number of the damping springs is four, and the damping springs are symmetrically distributed at both sides of the lamp holder respectively. The muber of the dampers is two, and the dampers are also symmetrically fixed on both sides of the lamp holder respectively. The lamp holder is fixed in a circular ring of the middle of the fixed ring, and both sides of the fixed ring are connected with the damping springs and the dampers respectively.

Description

Shockproof lighting device for mining machinery

The utility model is a kind of lighting that is used to have the sharp pounding occasion, belongs to the technical field of antidetonation lighting.

The various shockproof lamps that use are broadly divided into two big classes at present, and a class is to adopt damping spring or rubber blanket to delay in lamp chamber to shake.Another kind be light fitting body with add shock absorber between facility are connected.From the effect of using, the result of use of first kind light fixture is poor, uses (digger of using as mining) to need often more renew bulb on the bigger facility of vibration.Though and the life cycle of bulb prolongs to some extent than first kind light fixture in the second class light fixture, in the abominable place of environment, its shock absorber vulnerable to pollution, damage, make its damping property to descend, influence result of use.

It is good that goal of the invention of the present utility model provides a kind of buffer shock-absorbing performance, and have the antidetonation facility illuminating lamp of pollution-proof performance.

Antidetonation facility illuminating lamp of the present utility model mainly is made up of protection lampshade (1), translucent cover (2), reflector (3), bulb (4), lamp socket (5), vibration absorber (6), transformer (7), trigger (8), shell (9), wherein reflector and bulb all are fixed on the lamp socket, lamp socket is fixed on the vibration absorber, and protection net and translucent cover are fixed on the front end of shell.Vibration absorber is made of damper (10), shock-absorbing spring (11), retainer plate (12), support (13), wherein, shock-absorbing spring has 4, be in the both sides of lamp socket respectively symmetrically, one of shock-absorbing spring is fixed on the retainer plate, and the other end is fixed on the support by " U " shape plate (14) and set screw (15).Damper has two both sides at the bottom of being separately fixed at lamp, on the limit that is fixed on retainer plate, the other end is fixed on the base plate of support, retainer plate is made of by semicircular iron ring the centre of two symmetries up and down, the straight portion at its two ends is connected with damper with shock absorber, and lamp socket is in the middle annulus of retainer plate.

Adopt its advantage of antidetonation facility illuminating lamp of the present utility model to be, since adopted distinctive active damping mode, the Lights section and luminaire body is isolated, the Lights section is suspended in the lamp chamber by vibration absorber, by the shock-absorbing spring control high frequency district that shakes, by the damper inhibition low frequency district that shakes.Like this, though in use light fitting body is subjected to strong vibration, bulb itself can never produce resonance.The passive vibration damping mode that adopts in the vibration damping mode of this active and the former various antidetonation light fixtures has the different of essence.Therefore, this light fixture can prolong the service life of bulb effectively, can be useful in various occasions with judder widely.

Fig. 1 is a general structure schematic diagram of the present utility model.

Fig. 2 is the structural representation of vibration absorber.

Fig. 3 is the vertical view of Fig. 2.

Embodiment of the present utility model is as follows:

Protection net (1) adopts steel wire to form very sparse net, mainly is to block bigger object.Translucent cover (2) is made by glass, and the rear portion of reflector (3) is installed on the lamp socket (5), and bulb (4) adopts high-pressure mercury lamp, also directly is fixed on the lamp socket.Vibration absorber mainly comprises shock-absorbing spring, damper, retainer plate, support.Shock-absorbing spring is extension spring, has 4, is fixed on the both sides of lamp socket respectively symmetrically, and of every spring is connected with retainer plate, and the other end is connected on " U " shape plate, and " U " shape plate is connected with the side of support by set screw.Damper adopts isolation damper without resonant peaks, its bottom is connected with the bottom of support, its top is fixed on the mid portion on retainer plate both sides, retainer plate is a semicircular in shape in the middle of two, both sides are iron plates of straight flange, these two parts are symmetry up and down, when two parts up and down close when disturbing, forms a complete retainer plate.Lamp socket just is fixed in the middle annulus of this retainer plate.Support is also made for iron plate, mainly has been the fixedly effect of vibration absorber.According to the above, just can make antidetonation facility illuminating lamp of the present utility model.
