Abstract
The utility model belongs to the technical field of safety monitoring of bridge cranes, and particularly relates to a wireless-network-based large-scale bridge hoisting machinery metal structure safety monitoring device which overcomes the defects that wiring time is long and circuits influence the normal working of equipment in the conventional wired monitoring system of the bridge crane. The wireless-network-based large-scale bridge hoisting machinery metal structure safety monitoring device comprises a plurality of strain gauges on top flange plates and bottom flange plates of bridge crane girders; the stain gauges are connected with a telemetry strain indicator transmitter through an analog-to-digital conversion circuit; and a telemetry strain indicator receiver which receives signals transmitted by the telemetry strain indicator transmitter is connected with a data acquisition card which is arranged in a computer. The utility model has the advantages that the stress of the metal structure of the bridge crane can be monitored in real time, so that the deformation, breakage and other failure accidents which are caused by overlarge stress applied to the metal structure can be avoided, the construction time is short, the working of equipment is not interfered, and the whole monitoring time is shortened effectively.
Description
Technical field
The utility model belongs to the technical field of the safety monitoring of crane in bridge type, specifically, relates to a kind of large bridge crane tool metal construction safety monitoring assembly based on wireless network.
Background technology
Crane in bridge type is a kind of crane span structure type hoisting crane that frame moves on aerial conveyor.Metal construction plays vital reusing as the main load parts of overhead traveling crane machinery.The crane in bridge type cost is than higher, and safety case in use concerning the person and property safety constantly, in case have an accident, the lighter's device damage, weight person fatal crass, economic loss is heavy, social influence is abominable.
The crane in bridge type metal construction generally is made up of two box girders and two box-shaped end carriages, and girder and end carriage are affixed, is installation and operation mechanism and pedestrian's convenience; The girder web outside all is equipped with walks on stage, and segment section cuts in the end carriage, bolt together; So that transportation, like Fig. 1, shown in Figure 2.The position that crane in bridge type stress is maximum, most probable takes place to lose efficacy is the spaning middle section of girder.
At present, the monitoring system of crane in bridge type is many based on ray mode is arranged, because monitoring channel is more, this pattern has the shortcoming of wiring time length, line influence equipment normal operation.
Summary of the invention
Wiring time is long, the shortcoming of line influence equipment normal operation for the monitoring system that ray mode is arranged that solves existing crane in bridge type is stored in for the utility model, and a kind of large bridge crane machinery metal construction safety monitoring assembly based on wireless network is provided.
The utility model adopts following technical scheme to realize:
A kind of large bridge crane machinery metal construction safety monitoring assembly based on wireless network; Comprise the top flange plate that is installed in bridging crane main beam and the some strain-gaugies on the bottom wing listrium; Strain-gauge links to each other with the telemetry strainometer emitter through analog to digital conversion circuit, and the telemetry strainometer receiver of the signal that reception telemetry strainometer emitter sends is connected with the data collecting card in being installed on computing machine.
The utility model is to manufacture on the basis in existing large bridge crane structure; Outfit is based on the metal construction safety monitoring system of wireless network; Through the wireless network monitor stress, thereby realize remote real time monitoring crane in bridge type metal construction, so that overcome the defective of prior art; For crane in bridge type safe life assessment and antifatigue design provide load parameter, for the safety and the economy of crane in bridge type metal construction provides the load data shoring of foundation.
The relative prior art of the utility model has following beneficial effect: owing to adopted the crane in bridge type metal construction monitor for stress based on wireless network; Therefore can realize the real-time stress monitoring of metal construction of crane in bridge type; Thereby the failure accidents such as excessive distortion that causes and fracture of having avoided meeting with stresses because of metal construction take place; It is short that this system has the time of building, and the advantage of interference apparatus work has not effectively shortened whole monitoring time.Simultaneously, through obtaining of loading spectrum, and analyze its regularity, the safe design method that can be crane in bridge type provides the data support.

The specific embodiment
Be described further in conjunction with the specific embodiment of accompanying drawing the utility model.
Large bridge crane machinery metal construction safety monitoring assembly based on wireless network; Comprise the some strain-gaugies 7 on the top flange plate 5 that is installed in bridging crane main beam 1 span centre and the bottom wing listrium 6; Strain-gauge 7 links to each other with wireless telemetering strain gage emitter through analog to digital conversion circuit, and the telemetry strainometer receiver of the signal that reception telemetry strainometer emitter sends is connected with the data collecting card in being installed on computing machine.3 of the strain-gaugies of top flange plate 5 top installation space 10mm; Middle strain-gauge is arranged at the span centre of top flange plate 5; 3 of the strain-gaugies of bottom wing listrium 6 following installation space 10mm, middle strain-gauge is arranged at the span centre of bottom wing listrium 6, and is as shown in Figure 2.
Test macro uses telemetry, and strain-gauge, analog to digital conversion circuit, transmitting set are made on the measurement module, and receiver is connected with microcomputer, accepts the signal that collects and makes subsequent treatment.The stress signal that strain-gauge measures sends signal through analog to digital conversion circuit, transmitting set, after being received by receiver, sends into computer system through data collecting card, analyzes.The total system principle of work is as shown in Figure 4.
