Abstract
The utility model discloses a windproof safety device for a construction elevator, which is characterized by comprising a wind speed sensor, an anemometer, and an intermediate relay controlled by the output of the anemometer; and the wind speed sensor is connected with a signal input port of the anemometer, an output control switch of the anemometer is connected in series in a coil working voltage loop of the intermediate relay, and a contact switch of the intermediate relay is connected in series in a coil working voltage loop of a hoisting main contactor of the elevator. The windproof safety device improves the safety of the construction elevator, guarantees the safety of constructors when wind speed in the upper air is high, and fills in gaps in the aspect of windproof safety of the construction elevator.
Description
Technical field
The utility model relates to a kind of safety device, particularly relates to a kind of building hoist windproof safety device.
Background technology
Along with China's construction market development, operating technique is constantly advanced, the construction of high-rise building is more and more, and building lifting vertical transportation machinery superelevation layer uses more and more higher, and lifting vertical transportation machinery original design range of use, instantaneous internal force exceed tolerance zone head and shoulders above.
According to relevant specification of country and standard " GB/T 3811-2008 hoist design specification " and " GB50009-2001 loading code for design of building structures " etc., wind loading to effects such as building operation lifting vertical transportation machinery or buildings, use height or highly increase and increase with building operation lifting vertical transportation machinery or building, the building operation lifting vertical transportation machinery that uses of superelevation layer particularly, the wind-engaging imposed load is just bigger, and danger is also big.For the superelevation layer that adapts to building hoist uses development and strengthens windproof safety, guarantee that building hoist normally uses safely, special superelevation layer uses, and it is very necessary that building hoist is installed windproof safety device.
The utility model content
The purpose of this utility model provides a kind of building hoist windproof safety device, reduces the danger that building operation lifting vertical transportation machinery brings because of the wind-engaging imposed load.
The purpose of this utility model can realize by following scheme: a kind of building hoist windproof safety device is characterized in that the intermediate relay that comprises that air velocity transducer, anemoscope, anemoscope output are controlled; Described air velocity transducer is connected in the signal input port of described anemoscope, the control of described anemoscope output switch series is connected in the coil working voltage circuit of intermediate relay, and the contact switch of described intermediate relay is serially connected with in the coil working voltage circuit of hoisting main contactor of elevator.
Described air velocity transducer fixedly places the top of building hoist cage.
Described building hoist windproof safety device also comprises anemometer, and the trigger end of described anemometer is connected with the control of described anemoscope output switch.
The utility model has improved the safety of building hoist, has guaranteed the safety of workmen when the high-altitude wind speed is big, has filled up the blank of building hoist at windproof secure context.
Description of drawings
Fig. 1 is the control system schematic diagram;
Fig. 2 is that the building hoist windproof safety device is installed and used structure explanation scheme drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the external structure of whole construction elevator comprises that end cage 1 is used to support the whole construction elevator; Electric system 2 is used for the electric power supply of building hoist; Guide rail bracket and attached wall frame 3, cable system 4, cage 5, transmission and speed limiting mechanism 6, suspension rod 7.Rail frame and attached wall frame 3 are used for the up-and-down movement track of cage 5; Cable system 4 is used for the power transmission of whole construction elevator.The utility model mainly is made up of the intermediate relay KA2 of air velocity transducer 8, anemoscope, anemoscope output control; Air velocity transducer is connected in the signal input port of described anemoscope, the control of anemoscope output switch series is connected in the coil working voltage circuit of intermediate relay, and the contact switch of intermediate relay is serially connected with in the coil working voltage circuit of hoisting main contactor of elevator.Air velocity transducer 8 is installed on the top of cage 5, be used to survey the wind speed of cage 5 outer atmosphere, anemoscope can be fixed in the cage interior driver operation chambers 5, connects by the four-core shielded cable between them, and air velocity transducer and anemoscope can adopt existing YHQ-1 model commonly used etc.
The main contactor K switch 3 of lifting mechanism and K switch 4 are connected in the middle of the rising and decline loop of motor, are used to control the rising and the down maneuver of motor, and are connected to power supply through main supply switch K2 and Q2.The contact switch of intermediate relay KA2 is serially connected with in the middle of the rising control loop, connects with K switch 3.The control output switch EY of anemoscope is serially connected with in the coil working voltage circuit of intermediate relay KA2.When wind speed surpasses certain rank, air velocity transducer is passed to anemoscope to signal, described anemoscope cuts off intermediate relay KA2 by handling output switching value EY (normally closed interlock disconnection) action, make the KA2 must not, the outage of KA2 intermediate relay can be cut off the main contactor K3 that cage 5 rises, so can cut off the power circuit that hoists, cage 5 can not upwards be moved, guarantee safety.But this moment, the lowering main contactor K switch 4 still can be worked, and cage 5 is moved downwards, allowed the people and the thing safe escape of cage 5 the insides.
The building hoist windproof safety device also comprises an anemometer, and the trigger end of anemometer is connected with the control of described anemoscope output switch.When anemoscope output switching value EY, trigger anemometer when cutting off intermediate relay KA2, anemometer is sounded and flashing light, reminds the workmen to note.
Claims (3)
1. a building hoist windproof safety device is characterized in that the intermediate relay that comprises that air velocity transducer, anemoscope, anemoscope output are controlled; Described air velocity transducer is connected in the signal input port of described anemoscope, the control of described anemoscope output switch series is connected in the coil working voltage circuit of intermediate relay, and the contact switch of described intermediate relay is serially connected with in the coil working voltage circuit of hoisting main contactor of elevator.
