Abstract
The utility model discloses a safety protection device for hoisting equipment within an abnormal working range and belongs to the technical field of electronics. The safety protection device comprises an initial moment limiter system, a sound and light alarm device and a controller, wherein the initial moment limiter system consists of a sensor, a host and the sound and light alarm device; the sound and light alarm device consists of a display and a buzzer; the controller is arranged inside a crane; and the sound and light alarm device and the sensor are respectively connected with the controller and the host through a control circuit. The safety protection device has the beneficial effects that the controller and a moment limiter simultaneously work within a normal working range to protect the safety of the crane; within the abnormal working range, the moment limiter loses a protecting function and the safety of the crane is protected by the controller; when the gravity center is positioned in a warning work area, the sound and light alarm device is started; and when the gravity center is positioned in a dangerous work area, the controller stops actions in a dangerous direction and transmits a corresponding sound and light alarm prompt so as to play a role of safety protection.
Description
Technical field
The utility model relates to a kind of safety guard, specifically is the safety guard in a kind of weight-lifting equipment non-normal working scope, belongs to electronic technology field.
Background technology
The limiter of moment of hoisting crane is very universal, prevent that at present the equipment that hoisting crane is tumbled from being limiter of moment, on the hoisting crane because cost consideration, one cover limiter of moment only is installed, limiter of moment is by gathering the related sensor parameter moment balance to be calculated, prevent to tumble, but limiter of moment fault or when the non-normal working scope (for example dismounting operating mode etc.) can't guarantee the moment safety of hoisting crane; In addition; hoisting crane action control only realizes auxiliary mutually function from moving at present; this operation operating mode movable crane is in actual use often used; but because effective protection of shortage power limit device; take place frequently to cause the accident of hoisting crane overturning because of shortage power limit device protection when the cocked operating mode; therefore, work out and aly can support that the controller of the safety guard-safeguard in the non-normal working scope is extremely important.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides the safety guard in a kind of weight-lifting equipment non-normal working scope, has solved the safety guard-safeguard problem of hoisting crane in the non-normal working scope effectively.
To achieve these goals, the technical solution adopted in the utility model is: the safety guard in a kind of weight-lifting equipment non-normal working scope, comprise initial moment killer system, form by sensor, main frame and acoustic-optic alarm, acoustic-optic alarm is made up of telltale and buzzer phone, also comprise being installed in hoisting crane in-to-in controller, acoustic-optic alarm is connected with main frame with controller respectively by control circuit with sensor; Software is installed in the controller, and the control telltale shows area of safety operaton, vigilance task zone, dangerous work zone and the present residing position of hoisting crane center of gravity; Controller adopts the CAN mode bus; Telltale in the initial moment killer is by CAN bus and host communication; Whether the initial moment killer, is protected hoisting crane in setting range by the weight that detects hoisting crane and hang year and the residing angle of crane arm; Whether controller, is protected hoisting crane in area of safety operaton by the data computation center-of-gravity position gathered.
The beneficial effects of the utility model are: work simultaneously in normal operating range internal controller and limiter of moment; the safety of protection hoisting crane; in the non-normal working scope, limiter of moment loses defencive function, protects the safety of hoisting crane by controller; when center of gravity in vigilance task when zone; acoustic-optic alarm is activated, when center of gravity in dangerous work when zone, controller will stop the action of dangerous direction; and send corresponding sound and light alarm prompting, play the safety guard-safeguard effect.
Description of drawings
Fig. 1 is an electric functional block diagram of the present utility model
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, safety guard in a kind of weight-lifting equipment non-normal working scope, comprise initial moment killer system, form by sensor, main frame and acoustic-optic alarm, acoustic-optic alarm is made up of telltale and buzzer phone, also comprise being installed in hoisting crane in-to-in controller, acoustic-optic alarm is connected with main frame with controller respectively by control circuit with sensor; Software is installed in the controller, and the control telltale shows area of safety operaton, vigilance task zone, dangerous work zone and the present residing position of hoisting crane center of gravity; Controller adopts the CAN mode bus; Telltale in the initial moment killer is by CAN bus and host communication.
The utility model comprises all devices of former power limit device system, and initial moment killer main frame acquired signal realizes specific logic by programming, and telltale is by CAN bus and host communication, and becomes by logic and to realize specific demonstration and buzzer warning; Increase controller simultaneously and be used to calculate hoisting crane moment when non-lifting operating mode; the go forward side by side safety guard-safeguard of line correlation; in normal operating range, work simultaneously with limiter of moment; controller is by gathering the sensor signal of former access limiter of moment; and the construction parameter by hoisting crane self; calculate the center-of-gravity position of current hoisting crane according to principle of moment balance, hoisting crane is protected.
When hoisting crane is worked in normal range, the signal of limiter of moment by receiving, judge whether hoisting crane works in the scope of setting, if exceed setting range, acoustic-optic alarm will be activated, and remind the staff to stop violation operation, reach certain numerical value when going beyond the scope after, the actuating of relay hoists and the operation of crane arm increase swinging radius will stop automatically; Controller is according to the data that collect, carry out data handing, calculate the center-of-gravity position of hoisting crane, on read-out, demonstrate simultaneously the center-of-gravity position of hoisting crane, area of safety operaton, the icon in vigilance task zone and dangerous work zone, when the center-of-gravity position of hoisting crane enters the vigilance task zone, controller starts acoustic-optic alarm by control circuit, reminding the staff to slow down goes slowly, according to the hoisting crane position that shows on the read-out, adjust hoisting crane, center-of-gravity position is adjusted in the area of safety operaton, and when center-of-gravity position entered into the dangerous work zone, controller will be by the control circuit starting relay, stop ongoing action, thereby guaranteed staff's safety.
