Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Based on the existing bridge inspection vehicle, it includes a telescopic arm 9, an operating room 7 and a vertical arm. The operating room 7 is installed on the vertical arm through a turntable 6, and the operating room 7 is hinged with the telescopic arm 9; The structure is located within a vertical arm.

[0027] like figure 1 , figure 2 Shown is a personnel lifting device for the vertical arm of a bridge inspection vehicle, which includes an electric drum 1, a wire rope 3, a guide device 4 and a passenger device 5; the electric drum 1 is fixed on the upper part of the vertical arm through a support 2, and the The steel wire rope 3 is wound on the electric drum 1, one end of the steel wire rope 3 is fixed to the electric drum 1, and the other end is fixed to the top of the passenger device 5, and the guide device 4 and the passenger device 5 are installed i...

Abstract

The invention discloses a personnel lifting device used for a vertical arm of a bridge detection vehicle. The personnel lifting device comprises a motorized pulley, a steel wire rope, a guide device and a passenger device; the motorized pulley is fixed at the upper part of the vertical arm through a support; the steel wire rope is intertwined on the motorized roller; one end of the steel wire rope is fixed with the motorized roller and the other end the steel wire rope is fixed with the top part of the passenger device; the guide device and the passenger device are both installed in the vertical arm, and the passenger device reciprocates along the guide device. The personnel lifting device used for the vertical arm of the bridge detection vehicle provided by the invention solves the problem that the lifting of personnel and heavy objects is difficult during the use of the bridge detection vehicle, and is beneficial to the promotion and development of the bridge detection vehicle; in the scheme, the passenger device can rotate synchronously along with an operating room and a telescopic arm, so that a worker can always face a two-revolution control panel, and the rotation of the passenger device will not cause the steel wire rope to be twisted, thus, the passenger device has wide practicability. The device is simple in structure, scientific and reasonable, safe and stable and high in reliability.

Description

technical field [0001] The invention relates to a personnel lifting device for the vertical arm of a bridge inspection vehicle, and is also suitable for lifting heavy objects between the main body of the bridge inspection vehicle and the telescopic arm. Background technique [0002] The bridge inspection vehicle can inspect, repair and maintain the bridge structure from all directions, and has been widely used in engineering. In the currently used bridge inspection vehicle, the staff goes back and forth between the main engine and the telescopic arm through the ladder in the vertical arm. When the telescopic arm rotates at a certain angle, the ladder in the operating room will form a misalignment with the ladder in the vertical arm, which will bring danger to the staff. When heavy tools are required for bridge inspection and maintenance, manual removal will obviously cause great inconvenience. Therefore, the lifting of personnel and heavy objects is an urgent problem to be...
