Abstract

The utility model discloses a bridge or road surface load-limiting protector. A pressure resisting cover is arranged at the top part of an air bag box, a plurality of air bags are arranged under the pressure resisting cover, air outlet holes and air inlet holes are arranged on the air bags, the air outlet holes are fixedly communicated with an air pressure adjusting valve and a quick release valve arranged on a swinging device in sequence, the quick release valve is fixedly connected with a swinging rod by a cylinder, and the swinging rod is movably connected with a main shaft. A plurality of main shaft seats are arranged on the main shaft, and automatic air inlet/outlet cut-off switches are arranged on the air outlet holes and the air inlet holes. With simple structure, good convenience, high practicability, good durability, low manufacturing cost, high safety, good reliability, easy installation and wide using range, the bridge or road surface load-limiting protector can avoid collapse of a bridge and damage to the road surface when in vehicle running. As an independent working system without power support, the protector can be installed on the bridge or the road surface in any place, and can achieve good effect. So long as the carrying capacity of a vehicle exceeds the set tons, the vehicle cannot cross the bridge or the road surface; if forced crossing is carried out, only the vehicle can be damaged and safety accidents cannot be caused.

Description

Bridge or road surface limit for tonnage protector

Technical field

The utility model relates to the protective device on a kind of bridge or road surface, especially a kind of bridge or road surface limit for tonnage protector.

Background technology

At present, under the driving of interests, truck men usually take a risk to overload, overweight hauling goods, some lawless people is made a breakthrough by force even, to escape law enforcement officer's inspection, especially in the mountain area, sometimes, if under the not enough situation of staff's supervision, overload, overweight situation are even more serious, dash by force close in, the on-the-spot device that there is no need mostly is equipped with, so that bridge collapses, and the road surface damage has caused serious economy loss to country; According to the situation that the applicant understands, the domestic protection equipment that this type of is not arranged as yet is in the inspection post; generally based on the manpower supervision, artificial input is bigger, needs special messenger's field control; as run into above-mentioned emergency case, and do not reach the function of supervision, also influence the normal operation of traffic simultaneously.

The utility model content

The purpose of this utility model provides a kind of bridge, road surface limit for tonnage protector simple in structure, convenient and practical, that bridge collapses and damage on the road surface in the time of can avoiding driving a vehicle, and not only durable in use, cost is lower, safe and reliable, and installation is easy, the scope of application is wider.

For solving the problems of the technologies described above, the technical solution of the utility model is:

This bridge or road surface limit for tonnage protector comprise: fork and main shaft, and pendulous device is fixedlyed connected with air bag case by tracheae; The air bag case top is provided with the resistance to compression cover, and it has a plurality of air bags, and air bag is provided with venthole and blowhole; Venthole is adjusted valve with the air pressure that pendulous device is provided with and fixedly is communicated with successively with quick release valve; Quick release valve is fixedlyed connected with fork by cylinder, and fork and main shaft flexibly connect.

Main shaft is provided with a plurality of spindle drums; Automatic cut-off switch when venthole and blowhole are provided with out with air inlet.

Air pressure is adjusted valve and can be replaced with artificial pneumatic control valve.

The beneficial effects of the utility model:

This utility model be a kind of simple in structure, convenient and practical, bridge collapses and bridge, the road surface limit for tonnage protector of road surface damage in the time of can avoiding driving a vehicle, not only durable in use, cost is lower, safe and reliable, install easily and the scope of application wider.

This protector is an independently work system, need not the electric power support, and bridge anywhere, road surface can be installed, and cost is low, effective, as long as vehicle load surpasses when setting tonnage, just can't pass through bridge or road surface, when breaking through by force, only vehicle can be damaged, security incident can be do not caused; If can be in conjunction with 110 command and control systems, it can be provided with an outpost of the tax office in the very first time, flees to the offender and causes difficulty, for the police tries to gain time precious to one.

Description of drawings

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

Fig. 1 is the structural representation of this protector when combining with automobile.

Plan structure schematic diagram when Fig. 2 is two protector combinations.

Fig. 3 is the structural representation of protector.

Fig. 4 is the left TV structure schematic diagram of Fig. 2.

The specific embodiment

According to Fig. 1-shown in Figure 4, the utility model mainly comprises: air bag case 1, air bag 2, tracheae 3, air pressure are adjusted valve 4, quick release valve 5, cylinder 6, fork 7, spindle drum 8, resistance to compression cover 9, venthole 10, blowhole 11, main shaft 12, pendulous device 13.

Pendulous device 13 is fixedlyed connected with air bag case 1 by tracheae 3; Air bag case 1 top is provided with resistance to compression cover 9, and it has a plurality of air bags 2, and air bag 2 is provided with venthole 10 and blowhole 11; Venthole 10 is adjusted valve 4 with the air pressure that pendulous device 13 is provided with and fixedly is communicated with successively with quick release valve 5; Quick release valve 5 is fixedlyed connected with fork 7 by cylinder 6, and fork 7 flexibly connects with main shaft 12.

Main shaft 12 is provided with a plurality of spindle drums 8; Automatic cut-off switch when venthole 10 is provided with out with air inlet with blowhole 11.

Air pressure is adjusted valve 4 and can be replaced with artificial pneumatic control valve.

Operating principle: this equipment adopts is that the external world exerts pressure power is provided, and without the power supply support, is not subjected to geographic restriction, and this equipment is mainly adjusted valve, quick release valve, cylinder, fork by air bag case, tracheae, air pressure and formed.

Vehicle rolls air bag case, line transportation air pressure is given in air bag case work, arrive air pressure then and adjust valve,, be transported to cylinder again if air pressure reaches when limiting tonnage pressure, stretching, extension boosted fork after cylinder obtained pressure, fork lifting miter angle, bar head just in time are the critical positions of vehicle apart from the height on 60 centimeters on ground, so overweight vehicle dare not be rushed in by force, if vehicle rollback has left air bag case, the air pressure in the cylinder will pass through quick release valve, air pressure is bled off, fork will be regained fast, recovers the smooth-riding surface, if be installed to when establishing the card function, just can finish as long as adorn an Artificial Control valve, light again car also can't be broken through.
