Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments.

Referring to fig. 1-4, the embodiment provides a safety pedal for a crane operating room, which comprises a fixed plate 1, a rotating shaft 2 and a pedal 3; the fixed plate 1 is mounted on a vehicle body 14 below an operation chamber 13 through bolts, one end, facing the edge of the vehicle body 14, of the fixed plate 1 is connected with the pedal 3 through the rotating shaft 2, and one end, connected with the rotating shaft 2, of the fixed plate 1 extends to the outer side of the vehicle body 13, so that the pedal 3 can rotate downwards by 90 degrees around the rotating shaft 2 and cannot be blocked by the vehicle body 14; the bottom surface of the pedal 3 is connected with an arc-shaped plate 4 through a bolt, one surface of the arc-shaped plate 4 facing the direction of the vehicle body 14 is an outward convex arc-shaped surface 5, and the arc-shaped plate 4 is made of a lighter thermoplastic resin material; the outer side surface of the vehicle body 14 is provided with a limiting groove 6, the bottom surface of the pedal 3 is connected with a limiting block 7 which can be matched with the limiting groove 6 at a corresponding position, and when the pedal 3 rotates downwards for 90 degrees, the limiting block 7 can be inserted into the limiting groove 6 for fixing, so that the pedal 3 is prevented from freely rotating when a vehicle runs on a bumpy road surface.

In order to control the pedal 3 to rotate, three brackets 8 which are distributed in parallel are arranged at the bottom of the vehicle body 14, the cross section of each bracket 8 is of a U-shaped structure, and the top end of each bracket 8 is connected with the bottom surface of the vehicle body 14 through a bolt; a telescopic mechanism 9 is installed in each support 8, the telescopic mechanisms 9 are telescopic hydraulic cylinders, controllers of the telescopic hydraulic cylinders are installed inside and outside an operation room 13 respectively, and workers can control the telescopic mechanisms 9 to work from the inside and the outside of the operation room 13 respectively. The telescopic end of the telescopic mechanism 9 is of a hemispherical structure and can be in contact with the arc-shaped surface 5 of the arc-shaped plate 4, when the telescopic end of the hydraulic cylinder extends to the longest, the arc-shaped plate 4 is pushed towards the outer side of the vehicle body 14, so that the pedal 3 is in a horizontal state, and when the telescopic end of the hydraulic cylinder extends to the shortest, the pedal 3 is basically vertical to the vehicle body under the influence of gravity; the telescopic hydraulic cylinder is preferably a 2-ton flange type heavy oil cylinder, the stroke is 0-6000mm, and the maximum pressure is 16 mpa.

Because the height of the crane body 14 is about 1.5m, in order to facilitate the workers to get on and off the crane body 14, the pedal 3 is connected with the pedal 10 at one end far away from the fixed plate 1, and the pedal 10 is of a U-shaped structure, so that when the pedal 3 is vertical to the crane body 14, the pedal 10 can be stepped on to get on and off the crane.

The pedal 3 is a square plate, the top surface of the pedal 3 is provided with an anti-skid pad 11 and a plurality of illuminating lamps 12, and the anti-skid pad 11 is made of rubber and is positioned in the center of the top surface of the pedal 3; the plurality of illuminating lamps 12 are LED down lamps, are distributed on the edge of the top surface of the pedal 3, can play a role in skid resistance and illumination, and are suitable for working at night; the pedal 3 is provided with a plurality of grooves for installing the illuminating lamps 12, and the illuminating lamps 12 are embedded in the grooves, so that the surface of the pedal 3 is ensured to be kept flat; wires of the illumination lamp 12 may extend from the bottom of the step panel 3 and be electrically connected to a power source in the operation chamber 13, and the exposed portion of the wires may be attached to the step panel 3 and the bottom of the vehicle body 14 with an adhesive tape.

When not needing footboard 3, the flexible end through controller control telescopic machanism 9 slowly contracts to the shortest, footboard 3 loses flexible end and supports the back, can revolute 2 rotation down 90 degrees under the action of gravity and be perpendicular with automobile body 14, will promote footboard 3 and make stopper 7 get into spacing groove 6 in and fix, and footboard 3 is vertical downward this moment, and occupation space is little, does not influence the vehicle and traveles, and the staff can also step on the pedal 10 and go up the automobile body down.

When footboard 3 need be used, the flexible end through controller control telescopic machanism 9 slowly extends to the longest, footboard 3 overcomes the resistance of gravity and spacing groove 6 and upwards rotates 90 degrees around axle 2 and is the horizontality, and telescopic machanism 9 provides ascending holding power to footboard 3 through arc 4, make the staff can step on footboard 3 safely, it is very convenient when business turn over control chamber 13, improve the security, and can be flexible with controller control telescopic machanism 9 in control chamber 13, the simple operation.
