Abstract
The utility model relates to a parallel dolly laser buffer stop of gantry crane, it includes its characterized in that the main control system and installs laser obstacle avoidance sensor and the reflecting plate on parallel dolly, the laser obstacle avoidance sensor is connected through the cable with the main control system, shines the light beam to install on the reflector panel on another dolly and realizes the distance and survey through installing laser obstacle avoidance sensor on this dolly, install simultaneously to be used for controlling the control box that the dolly slows down and parks on the driving motor of parallel dolly, the control box passes through the cable and links to each other with the main control system.
Description
Technical field
The utility model relates to a kind of transfer crane, is specifically related to the parallel dolly laser anti-impact device of a kind of transfer crane, for the Anti-bumping protection to the parallel dolly of gate-type formula hoisting crane.Belong to elevator machinery technical field.
Background technology
Before the utility model is made, the parallel dolly of transfer crane crashproof another dolly hits after chi bumps against by being arranged on travel switch on dolly with being arranged on, and the contact of travel switch disconnects, and cut-out trolley travelling power supply realizes.It is made up of with the chi that hits that angle steel is made into being arranged on another dolly the travel switch that a group is arranged on dolly.Its working process is, when a dolly moves close to another dolly, or two dollies mobile in opposite directions near time, bump against for preventing two dolly vehicle bodies, the chi that hits on two dollies is first bumped against with travel switch, disconnect the contact of travel switch, cut off trolley travelling power supply, and dolly is stopped.Due to such anticollision device, to hit chi length longer, installation positioning difficulty is large, the roller contact face of hitting chi and travel switch is little, rocking of chi is hit larger during trolley travelling, sometimes the roller that chi can not collide travel switch is hit, dolly can not be stopped in time, the accident that two dolly vehicle bodies bump against occurs.Meanwhile, because the restriction of the stroke switch position installed by dolly, one group of travel switch can only be installed on dolly, therefore, can not realize first slowing down when dolly is close, the function of rear parking.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, when providing one can move close to another dolly according to transfer crane parallel dolly dolly, or when two dollies move close in opposite directions, prevents the fender guard that two dollies bump against.
The purpose of this utility model is achieved in that the parallel dolly laser anti-impact device of a kind of transfer crane, it comprises main control system and the laser obstacle avoidance sensor that is installed on parallel dolly and reflecting plate, described laser obstacle avoidance sensor is connected by cable with main control system, light beam shone on the reflector that is arranged on another dolly realize distance measurement by being arranged on laser obstacle avoidance sensor on this dolly, control box for controlling dolly ramp to stop is installed simultaneously on the drive motor of parallel dolly, described control box is connected with main control system by cable.
Compared with prior art, the beneficial effects of the utility model are:
This plant running is reliable, and measuring distance 0.1 ~ 50 meter, range of a signal 0 ~ 80 meter, pre-alarm, alarm distance can be arranged as required, and precision is high, accuracy rate is high, easy for installation, do not need installation to hit chi.Can realize first slowing down when dolly is close, the function of rear parking, reduce impact when dolly stops, rock, the SD card that alarm condition can carry stored in main frame is for subsequent query.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the parallel dolly laser crash-proof protecting equipment of the utility model transfer crane.
Detailed description of the invention
See Fig. 1, the utility model relates to the parallel dolly laser anti-impact device of a kind of transfer crane, there are two parallel dolly #1 and #2, every platform dolly comprises main control system and the laser obstacle avoidance sensor that is installed on parallel dolly and reflecting plate, described laser obstacle avoidance sensor is connected by cable with main control system, light beam shone on the reflector that is arranged on another dolly by being arranged on laser obstacle avoidance sensor on this dolly, sensor exports to main control system the signal detected with master die analog quantity 4 ~ 20mA, main control system converts actual distance by computing to analog signals and shows on host display, and provide corresponding control to export and voice message output, the control output signal wherein produced by main control system flows to the control box on the drive motor being arranged on parallel dolly, realize the deceleration crashproof to trolley travelling, the control of stopping.
