Description

Technical Field

[0001] The utility model relates to the technical field of truck crane operation, in particular to a high-position operating device for a truck crane. Background Art

[0002] The crane mainly includes: a base, a slewing column that can rotate above the base, and a boom system fixed to the top of the slewing column. The crane is usually installed on a car (including a trailer) to become a vehicle that integrates loading, unloading and transportation. According to the overall structure of the truck crane, it is divided into a folding truck crane and a straight-arm truck crane.

[0003] In the early days, the boom of truck-mounted cranes was mainly operated in the down-position mode, that is, the operator stood on the ground and operated the joystick on the hydraulic valve to control the boom or used a remote control. Since a cargo box was installed at the rear of the crane, the good line of sight required for operating the boom in the down-position mode depended on factors such as the door panel height and chassis height of the cargo box and the height of the operator. This resulted in a poor line of sight for the down-position mode, making it inconvenient to operate the boom to lift objects, and the use of a remote control would result in a higher original cost for the entire machine.

[0004] In the prior art, Chinese patent CN 204701541 U discloses a turntable seat ladder device for a truck-mounted crane transport vehicle, comprising a left bracket, a right bracket, a cross brace, a pedal, and a mounting plate. The left bracket and the right bracket are U-shaped bent pipes, which are parallel to the horizontal plane and have a certain inclination angle with the horizontal plane. The upper part is overlapped with the seat, and the bottom is fixed on the mounting plate, and the mounting plate is fixed to the leg box by bolts; the cross brace is evenly welded to the left bracket and the right bracket, and the pedal is an anti-slip plate bent into a U shape, buckled on the cross brace and then welded firmly. Although it has the advantages of simple structure, beautiful appearance, and easy disassembly and assembly, it does not have a control and operation function, and the distance between the ladder and the seat is large, resulting in a large space occupation, and is not suitable for a folding arm truck-mounted crane.

[0005] Chinese patent CN 204701541 U discloses a high-position operating device for a straight-arm truck crane, in which a seat frame is arranged at the middle and upper part of the upper slewing body. When the operator sits on the seat fixing plate, the operating sight of the boom is no longer affected by the door panel height and chassis height of the cargo box and the height of the operator, thereby improving the operating sight of the boom and facilitating the lifting of objects. However, the ladder in the patent is arranged on the turntable. For a folding-arm truck crane, if the high-position operating device in the patent is used, the folding arm will interfere with the ladder when in operation and retracted state. Therefore, the seat frame and ladder in the patent are not suitable for folding-arm cranes.

[0006] like Figure 1As shown, the high-position operating device of the existing folding arm truck crane is mostly a welded one-piece structure with profiles as the main frame and steel plates as auxiliary panels, which has a high manufacturing cost and a long distance between the ladder 11a and the seat frame 12a, which is not conducive to the miniaturization of the high-position operating device and affects its versatility on smaller folding arm truck cranes.

The materials used are more unified and universal, avoiding a wide variety of manufacturing materials and realizing the material standardization defined by the structural design to a great extent. When the structural form of the high-position operating device changes the operating direction, for example, when switching between left and right operating modes, only the first side plate 1113 and the treadle member 122 need to be made symmetrically, and the other parts can be arranged symmetrically, that is, the structural parts have symmetrical universality.

[0050] According to the above embodiments, it can be seen that the high-position operating device of the truck-mounted crane involved in the utility model has a simple and compact structure, occupies a small space and has good versatility.
