Description

Climbing lamp for loader

Technical Field

The utility model relates to a loader is light for ascending a ladder, especially a make things convenient for navigating mate to ascend a ladder from top to bottom light of usefulness night belongs to loader technical field.

Background

At present, most of loaders at home and abroad are not provided with a ladder climbing lamp, and the conventional cab top working lamp and the conventional front combined lamp can only irradiate a driving road and an operation surface and cannot provide the illumination requirements of a platform and a ladder. When a driver gets on or off a cab at night and passes through a boarding ladder and a platform, the driver can only use other lighting tools such as a flashlight, a mobile phone and the like, so that the driver is inconvenient and easy to step empty or collide with the body, and the accident potential is increased. Therefore, a small work lamp integrated on the rearview mirror of the cab of the loader is required to irradiate the ascending and descending channel of the ladder, and then the small work lamp is turned on and off in the form of a switch and automatic delay control.

Disclosure of Invention

The utility model aims at providing a can illuminate loader ascending stair of driver ascending stair and use light, when the ignition switch-on, the driver can realize that the ascending stair lamp lights and extinguishes through the switch-on and the disconnection of wane switch. When the ignition switch is turned off, the lamp lights up automatically, the driver can lock the door and window, get on the ladder freely, leave the vehicle with ease, and after a period of time (the value can be set), the lamp goes off automatically.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a loader is light for ascending a ladder, contains an ascending a ladder lamp, rocker switch, fuse and programmable delay relay, the ascending a ladder lamp is integrated on the rear-view mirror, makes the light beam can shine on platform and ascending a ladder, the ascending a ladder lamp is through the rocker switch and programmable delay relay and the fuse connection storage battery of and connect.

Furthermore, when the programmable delay relay is not electrified, the programmable delay relay is normally open, the electric switch is kept normally open after the programmable delay relay is electrified, the electric switch is automatically closed after the programmable delay relay is powered off, and meanwhile, the programmable delay relay enters a delay state, and when a set delay value is reached, the relay switch is restored to be normally open.

Further, when the electric lock shelves were in ON circular telegram shelves, programmable delay relay got electric, and the relay switch normally opens, at this moment, realized lighting and extinguishing of direct control ascending stair lamp through the rocker switch.

Further, when the electric lock gear returns to the OFF gear, the programmable delay relay loses power, the relay switch is closed, the step lamp is lightened, the programmable delay relay synchronously starts timing, after a set time value is reached, a counter in the programmable delay relay is reset, the relay switch returns to be normally open, and the step lamp is extinguished.

The utility model has the advantages that:

the utility model provides a demand that the driver will see clearly the ladder when climbing up and down the ladder night has been solved to the light, convenient operation, economical and practical. When can satisfying the temporary stop promptly, the lighting demand of ascending a ladder from top to bottom also can satisfy the operation that stops, leaves the lighting demand when the vehicle ascends a ladder, and the delay time can be according to different trades and operator custom, sets for before dispatching from the factory.

fig. 3 is a control circuit schematic diagram of the lighting lamp for the loader climbing ladder of the utility model.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1 to 3, an illuminating lamp for a loader climbing ladder comprises a climbing ladder lamp 2, a rocker switch, a fuse and a programmable delay relay.

The lamp 2 is integrated on the rear view mirror 1, and the light beam can irradiate the platform and the climbing ladder. When a driver works at night and temporarily stops the vehicle, in order to get on or off the vehicle conveniently, the ascending stair can be directly controlled to be turned on or off through the rocker switch K1 under the condition that the whole vehicle is kept in a power-on state; when a driver wants to stop and put out the fire, the driver can firstly put out the fire and extract the key according to the normal operation habit, at the moment, the stair climbing lamp 2 is automatically lightened, the platform and the stair are lightened, the driver closes the cabin door of the cab, leaves the vehicle, and after a period of time (the value can be set), the stair climbing lamp 2 is automatically turned off.

As shown in fig. 3, the utility model discloses a control circuit principle of light for loader ascending a ladder:

the positive pole of the ladder climbing lamp is connected with the positive pole of the storage battery through the rocker switch K1 connected in parallel, the programmable delay relay T1 and the fuse F1, and the negative pole of the storage battery is connected with the negative pole of the ladder climbing lamp. The programmable delay relay T1 is connected with the anode of the storage battery through a 2C line and an ignition switch.

Description of the principle:

f1 is a fuse; k1 is a rocker switch; t1 is a programmable delay relay, and is normally opened when not powered on, the switch is normally opened firstly after the power is powered on, the switch is automatically closed after the power is off, and simultaneously enters a delay state, and when a set delay value is reached, the switch is normally opened again.

The No. 1 line is the positive electrode of the storage battery and is always electrified; the No. 0 line is the cathode of the battery; the No. 10 line is a power supply of the stair climbing lamp; the No. 2C line is an electrified gear signal of the ignition switch, when the vehicle power supply is turned on, the No. 2C line is electrified, and when the vehicle power supply is turned off, the No. 2C line is not electrified.

When the electricity lock shelves were in the circular telegram shelves, 2C got the electricity, and the T1 switch is normally opened, at this moment, can realize lighting and extinguishing of direct control ascending stair lamp through rocker switch K1. When the electric lock gear returns to the OFF gear, the 2C is powered OFF, the T1 switch is closed, the stair climbing lamp is lightened, the T1 starts to time synchronously, after a set time value is reached, the counter in the T1 is reset, the T1 switch returns to be normally open, and the stair climbing lamp is extinguished.
