The device comprises a proximity transducer, laser level measuring instruments, a wireless liquid crystal radar and a safety device, wherein the proximity transducer is arranged at a position on the inner side of a cart wheel of the crane; the laser level measuring instruments are arranged at the two ends of each section of track of the crane; the wireless liquid crystal radar is arranged on a transverse beam of the crane; the safety device comprises a connecting plate for the crane and a rail clearing device; and the connecting plate comprises an upper part and a lower part which are connected with each other through a spring pin. The device has the beneficial effects that: the device belongs to a real-time automatic control means for the monitoring and the treatment of rail gnawing and derailment, wear of wheel rims and tracks can be reduced effectively, and the phenomenon of derailment can be avoided effectively.
Description
Technical field
The utility model belongs to the technical field of hoisting crane safe in operation, is specifically related to a kind of device of avoiding crane arm to gnaw rail and derailing.
Background technology
Along with development and national economy, the effect that hoisting crane play more and more in nation-building is big, the kind of hoisting crane is also along with working environment is divided into polytype.Like the transfer crane that the place is used, the hoisting crane of rails such as the crane in bridge type operation that the workshop is used all can run into the problem of gnawing rail; Light then reduce the work efficiency of equipment; Increase the weight of maintenance workload and operating cost expense, heavy then cause potential safety hazard, lead to the person or equipment breakdown.
Summary of the invention
The goal of the invention of the utility model: solve existing hoisting crane and gnaw rail and derailing problem.
The utility model adopts following technical scheme to realize:
A kind of device of avoiding hoisting crane to gnaw rail and derailing; It is characterized in that comprising proximity transducer, laser level survey meter, wireless liquid crystal radar and safety device; Described proximity transducer is installed on the cart wheel inner side of hoisting crane; Described laser level survey meter is installed in the two ends of every section track of hoisting crane; Described wireless liquid crystal radar is installed on the crossbeam of hoisting crane, and described safety device comprises the connecting panel of hoisting crane and rail cleaner, and connecting panel comprises through two parts about the spring pin bonded assembly.
The utlity model has following beneficial effect: be real-time automatic guidance measure, can effectively reduce the wearing and tearing of wheel rim and track gnawing rail, derailing monitoring and handling, but the more generation of effectively preventing derailment occurring.

Among the figure: 1-crane girder, 2-hoisting crane cross sill, 3-is wireless liquid crystal radar, 4-laser level survey meter, 5-rail cleaner, 6-wheel, 7-track, 8-safety chi, 9-binary pair, 10-spring pin, 11-weld, 12-trigger switch.
The specific embodiment
Avoid hoisting crane to gnaw the device of rail and derailing; Comprise proximity transducer, laser level survey meter 4, wireless liquid crystal radar 3 and safety device; Described proximity transducer is installed on the cart wheel inner side of hoisting crane; Described laser level survey meter 4 is installed in the two ends of every section track of hoisting crane; Described wireless liquid crystal radar 3 is installed on the crossbeam of hoisting crane, and described safety device comprises the connecting panel of hoisting crane and rail cleaner 5, and connecting panel comprises through two parts about spring pin 10 bonded assemblys.
Specify as follows:
Cart wheel inner side at crane in bridge type is installed proximity transducer respectively, adjusts the active distance of detection.Like this, no matter hoisting crane which direction operation to the left and right, the wheel vertical divergence will be excessive when soon gnawing rail, and sensor is also sent signal.After sensor acquisition is delivered to PLC to signal, judge and corresponding adjustment motor speed by PLC, make hoisting crane big/wheel of dolly both sides reaches synchronous rotation.
Simultaneously the laser level survey meter all is installed, thereby is measured the levelness of track at every section track two ends.As shown in Figure 2; Because foundation deformation, when causing certain section parallel track degree overproof, by an orbital motion time to another track; Just the phenomenon that rail or derailing all appear gnawing in the both sides wheel might appear; At this time adopt proximity transducer adjustment left and right wheels rotating speed, just no longer play the effect of avoiding gnawing rail, so avoid derailing and gnawing rail and should consider above two kinds of measures simultaneously.
Because the track deformation that foundation deformation causes is not formation in a day; It is a dynamic process; And crane track is long because of orbital distance unlike train, and the stroke of hoisting crane is far smaller than the stroke of train, and the cost or the acceptable of laser level survey meter is installed; This just provides possibility for dynamic monitoring, and signal processing flow is: the wireless PLC of being transported to of collecting sensor signal carries out signal conditioning and electric machine control.
For the situation that possibly occur foreign matter on the track, adopt wireless liquid crystal radar, the installation site of wireless liquid crystal radar is as shown in Figure 3, and wireless liquid crystal radar melts wireless connections, driving radar, Color Liquid Crystal Display, BP caution sound in one.Just can both can pass through video again during the hoisting crane operation, and remind the driver to note having on the track situation of foreign matter as reversing automobile through the frequency of sound.
When adopting wireless liquid crystal radar, add a cover safety device again, the two parts that are divided into that this installs the rigid attachment of traditional rail cleaner expection middle rank connect with spring pin between two parts.Like Fig. 4,5, shown in 6.Rail cleaner is installed in the cross sill end of the end carriage or the transfer crane of crane in bridge type, during the hoisting crane operation, when finding that foreign matter appears in track; If when in a single day wireless liquid crystal radar goes wrong or driver when not having timely discovery situation, safe chi can at first be run into the foreign matter on the track, if the foreign matter quality is not very big; Then under the elastic force of spring pin itself, with foreign bodies removal, in the time of excessive as if the foreign matter quality; When only leaning on the elastic force of spring pin to be not enough to remove foreign matter, Fig. 1-4A can be moved to the dotted line position of view in the rail cleaner bottom, and at this time trigger switch is triggered; Crane at this time cuts off the power supply; Drg is had an effect, and final hoisting crane stops, thereby avoids the generation of accident.
