Abstract

The utility model relates to a warning device for the lifting of a skip bucket of a self dumping truck, which belongs to a safe auxiliary device of vehicle. The utility model comprises power supply, a skip bucket position detecting switch (3) which is connected by a conducting wire and a warning signal generating device, wherein the skip bucket position detecting switch is composed of an outside sealed impact-absorbing cover (5), a casing body (6) and a tactile rod (7), a spring (8), a fixed wafer (9), a movable wafer (10) and a connecting conducting wire (11) which are arranged in the casing body; the sealed impact-absorbing cover covers the outer part of the casing body, the fixed wafer is fixed to the inner wall of the casing body and is led outside the casing body by the connecting conducting wire, the movable wafer is arranged on the bottom end of the tactile rod, the tactile rod is arranged on the central position in the casing body and the tactile rod is sheathed with the spring. The warning signal generating device comprises an indicating lamp and a flasher; when the skip bucket is lifted or in a lifting state, the warning signal generating device sends out a warning signal; a driver is avoided driving under the condition that the skip bucket doesn't fall down, surrounding people avoid injury in an unloading process and the utility model has the positive effect of improving the guarantee of safe driving and safe operation.

Description

Dumping car tipping bucket lifting alarming device

" technical field " the utility model relates to a kind of vehicle safety accessory device, particularly belongs to a kind of dumping car tipping bucket lifting alarming device.

The dumping car that " background technology " generally used at present, mostly the operating system of its tipping bucket lifting is to adopt the electric-controlled hydraulic mode, in operator's compartment, operate, because of the driver inattention general idea forgets that the situation of putting down tipping bucket happens occasionally, cause vehicle to hang up the roadside electric wire in the process of moving, collide or be stuck in accidents such as culvert thus easily, cause very big loss for national wealth and individual personal safety.In addition, in the dump truck discharge process, the material that tumbles in a large number also might cause damage near personnel.In present prior art, do not find the technical scheme that can address the above problem as yet.

" summary of the invention " the purpose of this utility model promptly is to provide a kind of later-model dumping car tipping bucket lifting alarming device, when being in the lifting state, sends in tipping bucket alarm signal, to remind the driver after unloading, in time tipping bucket to be fallen, simultaneously, when discharge operation, remind the field staff to note dodging, with the purpose that raising is travelled and job safety ensures.

Dumping car tipping bucket lifting alarming device disclosed in the utility model, comprise power supply and by lead bonded assembly tipping bucket position detecting switch (3) and alarm signal generating means, it is characterized in that, so-called tipping bucket position detecting switch (3) is made of the feeler lever (7) in exterior sealing impact-absorbing shell (5), housing (6) and the housing, spring (8), static contact (9), movable contact spring (10) and connecting wire (11); So-called sealing impact-absorbing shell (5) covers on the outside of housing (6); Static contact (9) is fixed on the inwall of housing, causes outside the housing by connecting wire (11); So-called movable contact spring (10) is installed in the bottom of feeler lever (7); Feeler lever (7) is arranged on the middle position in the housing, and its upper ring cap has spring (8); So-called alarm signal generating means comprises indicator lamp (16) and series connected with it Der Blink und Abblendschalter (15).

Dumping car tipping bucket lifting alarming device disclosed in the utility model, owing to have tipping bucket position detecting switch (3) and alarm signal generating means, in the tipping bucket lifting or when being in raised state, send alarm signal, can avoid the driver under the situation that tipping bucket does not fall, to travel, perhaps in discharge process, injure people around person, have the good effect that improves safe driving and safe operation production guarantee.

" description of drawings " accompanying drawing part further discloses specific embodiment of the utility model, wherein:

Fig. 1, tipping bucket position detecting switch of the present utility model installation site scheme drawing;

Fig. 2, A-A is to enlarged diagram;

Fig. 3, the utility model circuit theory scheme drawing.

" specific embodiment " as shown in Figure 1, dumping car tipping bucket lifting alarming device disclosed in the utility model, its major part----tipping bucket position detecting switch (3) is installed on the inboard supporting plate (2) of dumping car chassis support beam (1), under the tipping bucket base plate (4), can avoids tipping bucket to rise and fall its in-to-in electric elements is impacted.

As shown in Figure 2, so-called tipping bucket position detecting switch (3) is made of sealing impact-absorbing shell (5), housing (6), feeler lever (7), spring (8), static contact (9), movable contact spring (10) and connecting wire (11).At tipping bucket base plate (4) when falling, movable contact spring (10) and static contact (9) break away from, when tipping bucket base plate (4) when lifting, under spring (8) effect, movable contact spring (10) contacts with static contact (9), and circuit is connected, the alarm signal generating means promptly sends signals such as light, sound, plays warning function.

As shown in Figure 3, so-called alarm signal generating means comprises being positioned at operator's compartment and exterior indicator lamp of car body (16) and series connected with it Der Blink und Abblendschalter (15).For improving the caution effect, so-called alarm signal generating means can also comprise the phonetic alarm device of being made up of speech chip (12), amplifying circuit (13), loud speaker (14), at tipping bucket position detecting switch (3) when being in closure, promptly send the warning clause of " tipping bucket is unloaded; take care " and so on, with remind the driver and on every side personnel note.

Obviously, the utility model also comprises power supply and lead, and so-called power supply adopts the dumping car storage battery to get final product.In addition, about the use and the method for attachment of power supply, lead, speech chip, amplifying circuit, loud speaker, Der Blink und Abblendschalter and indicator lamp, belong to all that those of ordinary skill is expected easily and realize easily, so do not do too much explanation.

Because dumping car tipping bucket lifting alarming device disclosed in the utility model, have tipping bucket position detecting switch (3) and alarm signal generating means, when tipping bucket is in lifting state and discharge operation, can send alarm signal, to remind the driver after unloading, in time tipping bucket to be fallen, remind the field staff to note dodging simultaneously, therefore have and improve the good effect that travels with the job safety guarantee.
