Description
Technical Field
The utility model belongs to the technical field of the hoist, concretely relates to large-tonnage crane cart operation interlocking alarm system.
Background
The large-tonnage crane and cart operation interlocking alarm system is an important part of safe operation of an operation mechanism, and the existing interlocking alarm system can meet the requirements, but still has the following phenomena:
1) when each mechanism of the large-tonnage crane runs, the alarm signal device can be switched on only by a pedal switch of a crane driver, so that the warning function can be realized.
2) When a crane driver turns on or off the pedal alarm device and operates the controller to 1-3 gears, the driver is easy to be distracted, the crane driver is mistakenly operated, and the heavy potential safety lifting hazard exists.
3) The alarm foot switch is connected with the power supply through wires outside, and the switch shell is metallic, so that the potential safety hazard of electric shock caused by damage exists.
4) When the inspection and maintenance personnel get on and off the crane and perform inspection or maintenance, the alarm signal device is arranged above the cab, the personnel is far away and cannot hear, and the personnel cannot see the light signal, so that the accident of crushing injury is easily caused.
5) The environment noise of the production site is more, various alarm signals are more, and the lifting injury accidents are easy to happen if the operators go up and down the crane and check and maintain the crane and distinguish bad sounds.
Therefore, a large-tonnage crane cart operation interlocking alarm system is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a large-tonnage crane cart operation interlocking alarm system.
The utility model provides a technical scheme that its technical problem adopted is: a large-tonnage crane and cart operation interlocking alarm system comprises a crane and a cab, wherein the crane is provided with an end beam, and a first alarm signal lamp is arranged on the end beam; the top of driver's cabin is equipped with the second alarm signal lamp, is equipped with the controller in the driver's cabin, and first alarm signal lamp passes through the cable series connection with the second alarm signal lamp, and first alarm signal lamp and second alarm signal lamp are controlled by the controller.
Specifically, the crane is provided with a main trolley and an auxiliary trolley, and the main trolley and the auxiliary trolley are controlled by a controller.
Specifically, a main beam and a secondary beam are arranged between the end beams.
Specifically, the top and the bottom of the end beam are provided with buffers.
The utility model discloses following beneficial effect has:
1) the system ensures personnel safety and eliminates lifting injuries.
2) The driver of the crane does not need to step on the alarm switch by feet, so that the time is saved, and the safe lifting of the crane is ensured.
3) The accurate and quick point inspection and the maintenance of equipment are realized, and the operating efficiency of personnel is improved.
4) The signal of the interlocking alarm device can be clear for the personnel getting on and off the crane at a glance, the anticipating and pre-controlling can be realized in advance, and the lifting injury is eliminated.
5) The ground personnel can also clearly distinguish the running state of the crane and eliminate the accident of falling and smashing at the high place.
Drawings
Fig. 1 is a schematic structural diagram of the crane of the present invention.
Fig. 2 is a schematic structural diagram of the cab of the present invention.
In the figure: 1-a buffer; 2-end beam; 3, a main beam; 4-secondary beam; 5-auxiliary trolley; 6-main trolley; 7-a first alarm signal lamp; 8-a second alarm signal lamp; 9-a cab; 10-a controller; 11-seat.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-2, the large-tonnage crane cart operation interlocking alarm system comprises a crane and a cab, wherein the crane is provided with an end beam 2, and a first alarm signal lamp 7 is arranged on the end beam 2; the top of driver's cabin 9 is equipped with second alarm signal lamp 8, is equipped with controller 10 in the driver's cabin 9, and first alarm signal lamp 7 passes through the cable series with second alarm signal lamp 8, and first alarm signal lamp 7 and second alarm signal lamp 8 are controlled by controller 10.
The crane is provided with a main trolley and an auxiliary trolley, the main trolley 6 and the auxiliary trolley 5 are controlled by a controller 10, and when the main trolley 6 or the auxiliary trolley 5 is started, the controller 10 simultaneously starts a first alarm signal lamp 7 and a second alarm signal lamp 8.
Be equipped with girder 3 and auxiliary girder 4 between end beam 2, the top and the bottom of end beam 2 all are equipped with bumper 1.
The utility model discloses a preparation method: the first alarm signal lamp 7 is arranged on the end beam 2 of the crane and is fixed firmly, and the installation position is obvious to personnel.
The wire tube is installed, the first alarm signal lamp 7 and the second alarm signal lamp 8 are connected in series through cables, a power line leads to the cab controller 10, and the isolating switch is installed before the controller 10, so that the alarm device can be turned on and off conveniently (the isolating switch is in a closed state during the night shift, and the number of spot inspection and maintenance personnel is small, and the isolating switch is in an open state during the day, so that the number of spot inspection and maintenance personnel is large during the day shift).
And a second alarm signal lamp 8 is arranged at the upper edge of the cab, and is easily observed by ground personnel at the installation position.
The power lines are connected in series and then connected into the controller 10, so that when the controller 10 is in a zero position, the lines are disconnected, and the controller 10 realizes that the alarm is in an on state on the gear.
The utility model discloses not be limited to above-mentioned embodiment, anybody should learn the structural change who makes under the teaching of the utility model, all with the utility model discloses have the same or close technical scheme, all fall into the utility model discloses an within the protection scope.
