Abstract
The utility model discloses an automatic monitoring hoist and mount operation area's bridge type hoisting apparatus has solved present driving to hoisting the region if there are personnel to carry out the problem of early warning. It is provided with travelling car (1) to include on bridge crane crane span structure (2), be provided with on the bottom surface under the box of travelling car (1) pyroelectric infrared sensor (4), be provided with alarm (5) on the box of travelling car (1), pyroelectric infrared sensor (4) link together with alarm (5) electricity, be provided with hoisting accessory (3) on travelling car (1), subaerial induction area (7) that are provided with pyroelectric infrared sensor (4) under hoisting accessory (3). The utility model discloses simple structure, it is convenient to maintain, is particularly suitable for the field usage.
Description
Technical field
The utility model relates to a kind of overhead traveling crane device, monitors, in particular to a kind of, the overhead traveling crane device whether lifting operation region has personnel.
Background technology
The use range of driving is throughout multiple industry fields such as machinery, iron and steel, chemical industry, buildings, along with the expansion of lifting business, the demand of lifting equipment safety operation is more and more higher. At present; at home in hoisting machinery industry; generally have employed various protector; as excess load slicer, tightly stop pass, zero position protection, position limitation protection, short circuit protection; but all only consider safety prevention measure from the machinery of driving itself and electric two aspects; in actual use, the accident not having strict implement safety regulation for operations to cause due to operator accounts for very vast scale.
Summary of the invention
The utility model provides the overhead traveling crane device in a kind of automatic monitoring lifting operation region, has personnel to carry out the technical problem of early warning in lifting region if solving existing driving.
The utility model solves above technical problem by the following technical programs:
The overhead traveling crane device in a kind of automatic monitoring lifting operation region, comprise Overhead Crane Bridge, Overhead Crane Bridge is provided with mobile dolly, the casing bottom surface of mobile dolly is provided with pyroelectric infrared sensor, the casing of mobile dolly is provided with warning howler, pyroelectric infrared sensor and warning howler are electrically connected, and be provided with lifting appliance, be provided with the induction region of pyroelectric infrared sensor on the ground of the underface of lifting appliance on mobile dolly.
Ground below Overhead Crane Bridge is provided with the teleswitch of warning howler.
Automatic monitoring lifting operation hazardous area safe safeguard system of the present utility model is different from conventional driving protection system; pay close attention under hanging weight of driving a vehicle in load process the safety problem passed through with or without personnel first; utilize pyroelectricity can respond to the technology of human body temperature; devise this cover safety precaution system; structure is simple; easy to maintenance, it is particularly suitable for onsite application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
The overhead traveling crane device in a kind of automatic monitoring lifting operation region, comprise Overhead Crane Bridge 2, Overhead Crane Bridge 2 is provided with mobile dolly 1, the casing bottom surface of mobile dolly 1 is provided with pyroelectric infrared sensor 4, the casing of mobile dolly 1 is provided with warning howler 5, pyroelectric infrared sensor 4 and warning howler 5 are electrically connected, mobile dolly 1 is provided with lifting appliance 3, the ground of the underface of lifting appliance 3 is provided with the induction region 7 of pyroelectric infrared sensor 4.
Ground below Overhead Crane Bridge 2 is provided with the teleswitch 6 of warning howler 5. Warning howler 5 can cut out when operator carry out normal running, carry out normal operation with manipulation proof personnel.
Row hangs in safety regulation for operations clearly requirement must not be passed through being lifted on other operator's heads, and notes hanging whether there are other operations personnel near load in operation, in case there is collision accident. Safety operation specification everybody know, but in actual mechanical process, someone always does not observe working specification in order to easy to operate or carelessness, goes to the hazardous location of lifting operation. In order to improve existing driving safety protector; there is provided to the safe operation of lifting equipment and support reliably; hanging whether underface in load process has personnel to pass through by installing detecting unit monitoring driving below dolly; when monitored personnel by time send sound and light alarm to remind operator; and utilize the driving of MCU micro-chip control suddenly to stop by Wireless Note control unit; make driving avoid the accident of causing injury that disables that is absent minded due to operation personnel and that cause in operation process, meet weight handling equipment safety operation specification.
We need to design a kind of detecting unit and can detect out and have personnel to pass through below dolly in hazardous location to reach safety precaution requirement. At this, we select rpyroelectric infrared technology, and utilize radiotelegraphy to transmit data between detecting unit and control unit. The principle of infrared rays wave band (8-12 micron) sensitivity that human body is mainly sent by this system based on pyroelectric infrared sensor (PIR) designs. By by 2 pyroelectricity sensor reversed polarity series connection, it is possible to offset the interference of environmental background thermal source, it is also possible to suppress the interference that own temperature raises and produce. The range of detector of pir sensor is generally less than 2 meters, and detection angle is 90-150 degree, in order to improve sensitivity and the range of detector of sensor, installs a Fresnel Lenses, the range of detector of PIR can be made to increase to 5 meters even longer to ten meters before sensor. PIR is also very big with the direction relations of human motion to the sensitivity of human body. This sensor is the most insensitive for moving radially reaction, moves then responsive for transverse direction. According to practical situation, lower " hazardous location " of driving we be generally chosen to be the circle that diameter is 3 to 4 meters, drive a vehicle and be highly generally about 10 meters. So pyroelectric infrared sensor is placed in dolly just below, people's movement on ground is just the sensitive direction of sensor. For reaching Detection results, settle special Fresnel Lenses in pyroelectric infrared sensor front so that it is range of detector reaches more than 10 meters, and detection angle is between 15 ��-20 ��, just cover " hazardous location " under driving.
