Abstract
The invention relates to an anti-collision system for an electric flatcar or other rail-type movement equipment, and particularly relates to an anti-collision system for an electric flatcar. The anti-collision system for an electric flatcar comprises the electric flatcar and a gate, and is characterized in that a front safety gear lever and a rear safety gear lever are fixed in front of and at the back of the electric flatcar respectively, a control cabinet and a wireless reception module are arranged on one side of the electric flatcar, an approach switch detection screw rod is fixed on wheels of the electric flatcar, a wireless transmission module corresponding to the wireless reception module is fixed at the upper part of the gate, and gate opening-closing position detection switches are fixed on the both sides of the lower part of the gate. The anti-collision system for the electric flatcar disclosed by the invention is unique in structure, high in sensitivity, far in detection distance, and adjustable in safety distance.
Description
Technical field
The present invention relates to the collision avoidance system of a kind of electric flat carriage or other rail type mobile equipment, especially relate to a kind of collision avoidance system of electric flat carriage.
Background technology
Electric flat carriage is the most frequently used device arrived between Oversize vehicle, and due to the carelessness of electric flat carriage operating personal, reductor drain pan bottom flatcar breaks by the foreign material that often generation electric flat carriage breaks on gate, workshop or track.The anticollision device can sought in the market mainly contains photoelectric switch, Reverse Sensor etc., but due to site environment restriction, cannot meet the demands.Photoelectric switch, easily by dust pollution, causes reflective insensitive, and it sends is light beam, and detection range is little, cannot meet the large-scale crashproof requirement of flatcar; Reverse Sensor can only detect that the obstacle within the scope of 1 meter is also easily subject to the interference of noise, and does not have enough safety distances.Also do not overcome the device of this problem at present.
Summary of the invention
The object of the invention is the defect overcoming prior art, provide that a kind of structure is unique, sensitivity is higher, detection range is far away, safety distance is adjustable electric flat carriage anticollision device.
The present invention realizes in the following manner:
A kind of collision avoidance system of electric flat carriage, it comprises electric flat carriage and gate, it is characterized in that: before and after being fixed with respectively in the front and back of above-mentioned electric flat carriage, safe lever, side are provided with control housing and wireless receiving module, the wheel of electric flat carriage is fixed with proximity switch and detects screw rod, be fixed with the wireless transmitter module corresponding with described wireless receiving module on the top at gate, both sides, bottom are fixed with the switch position, gate detector switch;
Described control housing is PLC control cabinet.
The present invention has following effect:
1) structure is unique: system provided by the invention it comprise electric flat carriage and gate, it is characterized in that: before and after being fixed with respectively in the front and back of above-mentioned electric flat carriage, safe lever, side are provided with control housing and wireless receiving module, the wheel of electric flat carriage is fixed with proximity switch and detects screw rod, be fixed with the wireless transmitter module corresponding with described wireless receiving module on the top at gate, both sides, bottom are fixed with the switch position, gate detector switch.
2) sensitivity is higher, detection range is far away, safety distance is adjustable: system provided by the invention is equal equal portions welding some screw rods on flatcar wheel, during rotation of wheel, PLC can count by proximity switch the current location accurately judging flatcar, the detection that gate is installed a large door opening and closing state is spacing, by wireless transport module, the on off state at limit signal and gate is real-time transmitted to flatcar controller; Lever is detected: bottom barrier is installed after ordinary building and detects lever after ordinary building, then on fixed gear rod bearing, retracing spring and travel switch are installed, when the foreign material on track knock this lever, travel switch action, flatcar can stop automatically, until operating personal is by eliminating impurities, lever automatically resets, and travel switch disconnects.Because the aspect ratio reductor on this lever distance ground is low, therefore, flatcar bottom part can be protected completely as the safety of reductor, motor etc.
3) use easy to operate: system provided by the invention arranges a R point in one end of flatcar track, as the benchmark that flatcar travel distance detects, then the distance between gate and bench mark is measured according to this benchmark, and this distance is deducted safety distance, refer to flatcar braking distance+safe clearance under normal circumstances, be set in PLC control system, as the foundation judged whether close to gate; When electric flat carriage runs, current location and perch can be made comparisons by PLC in real time, after entering the safety distance of setting, if the information that PLC receives wireless transport module transmission is that gate reaches position completely, then flatcar can pass through, otherwise PLC can force to stop, until gate is opened completely, but now, according to PLC program design, can continue to run to reversing sense.
4) cost of manufacture is low: the coder that flatcar wheel is installed, coordinate the general position switch that gate is installed, achieve the face protection on mobile device service direction, flatcar in the present invention controls to adopt PLC, the distance detection function of matching coding device, position residing in flatcar track, gate can be changed arbitrarily, prevent flatcar from breaking the safety distance at gate also unrestricted, portable strong, key function element of the present invention, as coder, crashproof detection lever etc., major part is made products, simple and practical, promotional value is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
A kind of collision avoidance system of electric flat carriage, it comprises electric flat carriage 3 and gate 11, as shown in Figure 1: before and after being fixed with respectively in the front and back of above-mentioned electric flat carriage 3, safe lever 5, side are provided with control housing 4 and wireless receiving module 6, the wheel of electric flat carriage 3 is fixed with proximity switch and detects screw rod 2, be fixed with the wireless transmitter module 7 corresponding with described wireless receiving module 6 on the top at gate 11, both sides, bottom are fixed with the switch position, gate detector switch 8.
Described control housing 4 is PLC control cabinet.
