Abstract
The invention relates to a safety device, in particular to a bin door safety device for a crane, and belongs to the technical field of safety protection of bin doors of cranes. According to the technical scheme, the bin door safety device for the crane comprises a crane base bin and a sliding door located on the crane base bin. A sliding door opening and closing detection sensor used for detecting the opening and closing state of the sliding door and a power supply protector used for adjusting the power supplying state of a crane power supply are arranged on the crane base bin. The sliding door opening and closing detection sensor and the power supply protector are both connected with a crane controller. The bin door safety device is compact in structure and convenient to use, and safety of objects and staff in the base bin is ensured when the crane works.
Description
Technical field
The present invention relates to a kind of safety device, especially a kind of hoisting crane door safety device, belongs to the technical field of hoisting crane door safety precaution.
Background technology
At present, hoisting crane is in harbour, stockyard are widely used, the bulk goods such as lifting sandstone, ore, coal, but the door in existing lifting support storehouse is all common door, dangerous, particularly when door opens, hoisting crane is when doing gyroscopic movement, due to the effect of inertia, be easy to just the article in storehouse, personnel to be thrown out, cause safety misadventure.Have potential safety hazard, production safety can not get ensureing.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of hoisting crane door safety device, its compact conformation, easy to use, to the safety of article and personnel in seat storehouse when guaranteeing that hoisting crane works.
According to technical scheme provided by the invention, described hoisting crane door safety device, comprises lifting support storehouse and is positioned at the sliding door on described lifting support storehouse; Described lifting support storehouse arranges sliding door closing detection sensor for detecting sliding door on off state and for regulating the power supply protector of hoisting crane Power supply state, described sliding door closing detection sensor, power supply protector are all connected with crane controller.
Described sliding door closing detection sensor comprises limit switch, and power supply protector comprises circuit breaker.
Described lifting support storehouse is also provided with the indicator lamp for safety instruction, described indicator lamp is connected with crane controller.
The top in described lifting support storehouse is provided with arm connecting strap.
Advantage of the present invention: the on off state being detected sliding door by sliding door closing detection sensor; when sliding door is opened; crane controller cuts off the power supply to hoisting crane by power supply protector; only have when sliding door is closed; crane controller just can by the power supply of power supply protector connection to hoisting crane; when guaranteeing work, the safety of article and personnel in hoisting crane door.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1-lifting support storehouse, 2-circuit breaker, 3-limit switch, 4-indicator lamp, 5-sliding door and 6-connecting strap.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: to the safety of article and personnel in seat storehouse when working in order to ensure hoisting crane, the sliding door 5 that the present invention includes lifting support storehouse 1 and be positioned on described lifting support storehouse 1; Described lifting support storehouse 1 arranges sliding door closing detection sensor for detecting sliding door 5 on off state and for regulating the power supply protector of hoisting crane Power supply state, described sliding door closing detection sensor, power supply protector are all connected with crane controller.
Particularly; lifting support storehouse 1 can be passed in and out by sliding door 5; detecting sliding door 5 by sliding door closing detection sensor is that place has open mode or closed condition, hoisting crane power supply can be made to power to hoisting crane by power supply protector or hoisting crane supply disconnecton to the power supply state of hoisting crane.Crane controller is a kind of control convenience controlling hoisting crane work, and the concrete structure of crane controller etc. all can adopt existing conventional form, are specially known by the art personnel.During specific works, the on off state detecting sliding door 5 transfers in crane controller by sliding door closing detection sensor, crane controller is according to the on off state of sliding door 5, carry out the power supply state being regulated hoisting crane power supply by power supply protector, namely when sliding door 5 is in open state, crane controller cuts off the power supply of hoisting crane power supply by power supply protector, and only when sliding door 5 is in off status, crane controller just makes hoisting crane power supply power to hoisting crane by power supply protector, hoisting crane power supply is only had to power to hoisting crane, hoisting crane just can work normally.Hoisting crane power supply can be civil power or required electrical source of power.
Described sliding door closing detection sensor comprises limit switch 3, and power supply protector comprises circuit breaker 2.Described lifting support storehouse 1 is also provided with the indicator lamp 4 for safety instruction, described indicator lamp 4 is connected with crane controller.Whether, in the embodiment of the present invention, limit switch 3 is positioned at the side of sliding door 5, detect sliding door 5 open or close by limit switch 3.Crane controller can control the electriferous state of circuit breaker 2 coil, and according to the electriferous state of circuit breaker 2 coil, can adjust the power supply state of hoisting crane power supply to hoisting crane, specific implementation process, known by the art personnel, repeats no more herein.
The top in described lifting support storehouse 1 is provided with arm connecting strap 6.Arm connecting strap 6 is evenly distributed on the top in lifting support storehouse 1, and lifting support storehouse 1 can be connected with arm by arm connecting strap 6.
The present invention detects the on off state of sliding door 5 by sliding door closing detection sensor; when sliding door 5 is opened; crane controller cuts off the power supply to hoisting crane by power supply protector; only have when sliding door 5 is closed; crane controller just can by the power supply of power supply protector connection to hoisting crane; when guaranteeing work, the safety of article and personnel in hoisting crane door 1.
