According to the automatic opening device, the rotary normally closed type brake can be automatically opened under the condition of a certain wind speed, so that a rotary part of the tower crane can be rotated along with wind.
Description
Technical field
The utility model relates to the automatic device for opening of the normally closed trainstop of a kind of tower crane, is particularly suitable for the tower crane of revolution, trainstop employing normally closed.
Background technology
Acceleration along with urbanization process; High-rise, superelevation becomes increasing of building; The Large Towers machine also is increasing in architectural use, and in order to increase the traveling comfort of tower machine operation, increasing tower machine has adopted converter technique and torque motor technology; Particularly in order to improve rotating operating characteristic; Reduce the revolution effect of inertia, the turning motor on the Large Towers machine is increasing to have adopted torque motor to add eddy speed regulating and variable-frequency motor adds eddy speed regulating, and the brake mode of these two kinds of motors has all adopted the normally closed plate disc brake basically.Regulation adopts the normally closed trainstop should guarantee that rotating part should be able to freely rotate under greater than the 20m/s wind effect at wind speed in selecting according to GB-13752-1992 design of tower crane standard 6.2.3.4 trainstop; So on the normally closed brake turning motor, often be furnished with the electric wind mark; The driver can open a sluice gate function through the drg machinery of operation electric wind mark or motor itself; Open the revolution normally engaged brake, tower machine rotating part is freely rotated with wind-force.But two kinds of above-mentioned method of operation all need the driver to the tower machine, could operate, if when tower machine driver is absent from duty, do not know to come under the situation of strong wind again; Need tower machine rotating part to rotate with strong wind; Then need tower on the operating personal, trainstop is opened, when the tower machine is very high; Such operation trouble that just seems, but also have no small danger.
The utility model content
The utility model problem to be solved is to overcome deficiency of the prior art and provide a kind of under certain wind friction velocity; The normally closed trainstop can be opened automatically, makes the automatic device for opening of the tower crane rotation normally closed brake that tower machine rotating part can rotate with the wind.
The technical scheme that the utility model solves the problems of the technologies described above employing is: the automatic device for opening of this tower crane rotation normally closed brake; It is characterized in that: comprise storage battery, wind speed sensing appearance and measuring wind speed appearance; Described wind speed sensing appearance is installed in the position that tower machine framing member ventilates, and the measuring wind speed appearance is installed in the tower machine driver's cab, and storage battery is installed in the tower machine electrical control cubicles; Wind speed sensing appearance is electrically connected with the measuring wind speed appearance; Storage battery is electrically connected with the measuring wind speed appearance, and the measuring wind speed appearance is electrically connected with revolution electric wind mark and trainstop respectively through control circuit, and storage battery is measuring wind speed appearance, trainstop and the power supply of revolution electric wind mark.
The described storage battery of the utility model is the 24V direct-flow storage battery.
The utility model compared with prior art has the following advantages: the measuring wind speed appearance adopts the power supply of DC 24V battery feed, and immediately under the state that the tower machine is shut down, the measuring wind speed appearance also can normal operation, guarantees the automatic opening function of drg.Described storage battery not only can be for the measuring wind speed appearance provides power supply, and can be under the situation of revolving high-speed operation sudden power, prevent that trainstop from braking suddenly, revolution inertia is to the torsion effect of body of the tower.When the tower machine is worked, utilize the existing rectification DC power supply of tower machine to charge a battery, guarantee the electric weight of storage battery.After the whole working cycle of the automatic device for opening of normally closed trainstop is accomplished, cut off all power supplies of storage battery fgn, reduce the use of storage battery electric energy, thereby can for measuring wind speed appearance, trainstop and revolution electric wind mark electric energy be provided for more time.
Description of drawings
Fig. 1 is the utility model structure principle chart.
Fig. 2 is the utility model electrical schematic diagram.
The specific embodiment
Referring to Fig. 1 ~ Fig. 2; The utility model comprises storage battery 1, wind speed sensing appearance 2 and measuring wind speed appearance 3; Wind speed sensing appearance 2 is installed in the position that tower machine framing member does not keep out the wind, and measuring wind speed appearance 3 is installed in the driver's cab, and control circuit 4 and storage battery 1 are installed in the tower machine electrical control cubicles.Wind speed sensing appearance 2 is electrically connected with measuring wind speed appearance 3; Storage battery 1 is the 24V direct-flow storage battery; Storage battery 1 is electrically connected with measuring wind speed appearance 3; Storage battery 1 also is electrically connected with tower machine rectifying device 7 simultaneously, and measuring wind speed appearance 3 is electrically connected with trainstop 6 with revolution electric wind mark 5 respectively through control circuit 4, and storage battery 1 is measuring wind speed appearance 3, trainstop 6 and 5 power supplies of revolution electric wind mark.
Principle of work: the working power of tower machine trainstop 6 and revolution electric wind mark 5 is DC 24V, so the power supply of rotary braking itself and electric wind graticule circle can be provided by storage battery 1.Under the open circuited situation of tower machine incoming power, storage battery 1 gives the measuring wind speed appearance 3 power supplies, detects through 2 pairs of wind speed of wind speed sensing appearance.When wind speed meets or exceeds 20m/s, the Wind speed switch FSKG action in the measuring wind speed appearance 3, relay K A1 gets electric, and trainstop 6 is opened, and through on-delay make contact KA1 time-delay, relay K A2 gets electronic work, and electric wind graticule circle gets electric, the inspiration block.After the block inspiration, the switch motion of electric wind mark, relay K A3 gets electronic work, and relay K A1 outage simultaneously discharges, and lock under the trainstop is put the jail on block.Relay K A1 discharges and causes that relay K A2 outage discharges, and relay K A3 discharges through outage time-delay break contact KA2 delay cut-off.So far whole end-of-job makes trainstop be in open mode through block, and tower machine rotating part can freely rotate with the wind.After whole working cycle was accomplished, all relays, coil be no power all, reduced the use of storage battery electric energy, can the longer time for wind speed measuring device electric energy be provided.
Above content described in this specification sheets only is the casehistory that the utility model structure is done.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from the structure of the utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
