Abstract

The utility model discloses a loosening-resistant warning device for a counter weight of an excavator. The counter weight is fixedly connected with an excavator platform through a connecting bolt. The loosening-resistant warning device for the counter weight of the excavator is characterized by comprising a warner. A signal input end of the warner is connected with a pressure sensor, a signal input end of the pressure sensor is connected with a contact piece of the pressure sensor, the contact piece of the pressure sensor is arranged between the bottom of the excavator platform and a gasket of the connecting bolt, and the contact piece of the pressure sensor and the pressure sensor are further connected with a power source. The loosening-resistant warning device for the counter weight of the excavator detects the connecting state of the connecting bolt through the pressure sensor. When the connecting bolt is loosened, the warner gives a sound alarm, the problem that the dropping of the counter weight caused by the loosening of the connecting bolt is effectively resolved, and accidents are avoided.

Description

The anti-loose warning device of a kind of excavator counterweight

Technical field

The utility model relates to a kind of warning device, is specifically related to the anti-loose warning device of a kind of excavator counterweight.

Background technology

The main purpose of excavator is a digging material and transfer to the emptying point from the face of land; Go back to excavation site after the discharging again; Repeating, is a kind of earth and rock works machinery of extensive use, normally operation under the operating mode of high load capacity; To each one, effectively, closely connecting each other between the assembly proposed very high requirement like this.Excavator generally all is to work in the open air, thereby the operating mode of excavator is comparatively abominable, the swing of machine during for the balance excavator operation; Generally all need be provided with counterweight; Counterweight has played ensureing the stable effect of excavator as the vitals of balance excavator, normally is made up of counterweight shell and balancing weight; Balancing weight is poured in the good housing of welding with the form of cement paste, and wildcard weighs bolt and the excavator platform is fixed.

At present, counterweight is to be fixed on the excavator platform by four connecting bolts mostly, and excavator is after the work long period, because connecting bolt is to impact, vibrating under the operating mode and work, ease of connection gets loose, and causes bigger potential safety hazard.To this phenomenon; Mainly all be to adopt to tighten connecting bolt once more and prevent bolt looseness; But under the situation of complex working condition and long-term operation and under the artificial carelessness situation, connecting bolt still has loosening unavoidably even comes off, thereby has influenced the reliability of counterweight; Cause coming off of counterweight, cause unexpected generation.

Summary of the invention

The goal of the invention of the utility model provides the anti-loose warning device of a kind of excavator counterweight, uses this device, can effectively prevent the accident that gets loose and cause counterweight to come off causing because of connecting bolt.

For reaching the foregoing invention purpose; The technical scheme that the utility model adopts is: the anti-loose warning device of a kind of excavator counterweight; Said counterweight is fixedly connected with the excavator platform through connecting bolt; Said warning device comprises an alarm, and said alarm signal input part is connected with pressure sensor, and said pressure sensor signal input is connected with the pressure sensor contact; Said pressure sensor contact is arranged between the packing ring of said excavator platform bottom and said connecting bolt, also is connected with power supply with said pressure sensor.

In the technique scheme, said pressure sensor contact is installed between the packing ring of excavator platform bottom and connecting bolt, and additional weight hoisting is after on the excavator platform; Carry out with connecting bolt fastening, after connecting bolt is fastening, lucky compaction pressure sensor contact; Contact is in closure state, produces signal feedback and gives pressure sensor, alarm module attonity; It is normal to show that counterweight connects, and connecting bolt does not have and gets loose; After the connecting bolt generation got loose, contact gave the alarm because the tension force effect of contained spring is in open configuration, and no signal passes to pressure sensor, and alarm module is started working, and reminded the operator that connecting bolt is checked, prevented unexpected the generation.

Further technical scheme, said alarm are a kind of in buzzer siren or the phonetic alarm.

Because the technique scheme utilization, the utility model compared with prior art has advantage:

1. the utility model is through setting pressure sensor contact between excavator platform bottom and connecting bolt, and contact was not in impaction state when connecting bolt got loose, and fed back signal to pressure sensor; Alarm is not worked, and contact was in open configuration when connecting bolt got loose, the no signal feedback; Alarm equipment alarm; Thereby prevented that effectively connecting bolt from getting loose, improved the reliability that counterweight connects, avoided unexpected generation;

2. the utility model need not change existing structure on a large scale, is easy to realize;

3. the utility model is simple in structure, and is easy to use, and cheap, is fit to promote the use of.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment one;

Fig. 2 is a contact impaction state enlarged diagram among the utility model embodiment one;

Fig. 3 is a contact open configuration enlarged diagram among the utility model embodiment one.

Wherein: 1, counterweight; 2, connecting bolt; 3, platform; 4, alarm; 5, pressure sensor; 6, contact; 7, packing ring.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment one: referring to shown in Fig. 1 to 3; The anti-loose warning device of a kind of excavator counterweight; Said counterweight 1 is fixedly connected with excavator platform 3 through connecting bolt 2; Said warning device comprises an alarm 4, and said alarm signal input part is connected with pressure sensor 5, and said pressure sensor signal input is connected with pressure sensor contact 6; Said pressure sensor contact is arranged between the packing ring 7 of said excavator platform bottom and said connecting bolt, also is connected with power supply with said pressure sensor.

This device at first is installed in pressure sensor contact 6 between the packing ring 7 of excavator platform 3 bottoms and connecting bolt in use, and counterweight 1 is lifted on the platform; Use connecting bolt 2 fastening again, the connecting bolt after fastening just compresses contact, referring to shown in Figure 2; Contact is in closure state; The generation signal feedback is given pressure sensor, and the normal nothing of counterweight connection this moment gets loose, and alarm 4 is not sounded; When connecting bolt produces when getting loose, referring to shown in Figure 3, contact is because the effect of contained spring tension force is opened, and no signal feeds back to pressure sensor, alarm warnings of sounding this moment, and prompting operator counterweight gets loose, and need check.

Claims (2)

1. anti-loose warning device of excavator counterweight; Said counterweight (1) is fixedly connected with excavator platform (3) through connecting bolt (2); It is characterized in that: said warning device comprises an alarm (4); Said alarm signal input part is connected with pressure sensor (5); Said pressure sensor signal input is connected with pressure sensor contact (6), and said pressure sensor contact is arranged between the packing ring (7) of said excavator platform bottom and said connecting bolt, also is connected with power supply with said pressure sensor.
