Width-adjustable omni-directional movable portal frame

Abstract

The invention discloses a width-adjustable omni-directional movable portal frame. The width-adjustable omni-directional movable portal frame is characterized in that a moving mechanism is arranged atthe bottom of a supporting and adjusting mechanism, a movable cross beam in the supporting and adjusting mechanism is arranged inside a fixed cross beam in a sleeving mode, the movable cross beam andthe fixed cross beam are in a sliding fit mode of a slide block and a slide way, a lead screw track is arranged in the radial central position of the movable cross beam, one end of a lead screw is connected with a motor, a reinforcing shaft is arranged on the periphery of the lead screw, side supporting beams are fixed below the opposite ends of the fixed cross beam and the movable cross beam, side supporting beam bases are fixed to the bottom surfaces of the side supporting beams, reinforcing supporting legs are arranged on the two sides of the side supporting beams, the upper ends of the reinforcing supporting legs are fixedly connected with the side surfaces of the side supporting beams, the lower ends of the reinforcing supporting legs are fixedly connected with the side supporting beam bases, the moving mechanism comprises load wheels, the lower end of each side support beam is provided with one load wheel through a connecting piece, and wheel hub motors are arranged on the load wheels. The portal frame can move in an omni-directional mode, the width can be adjusted in a grading mode, manpower can be reduced, the production operation cost can be reduced, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to scaffolding for construction, in particular to an all-round movable gantry frame with adjustable width. Background technique [0002] In the field of construction, the frame body used as scaffolding is generally a gantry frame. [0003] The traditional mobile gantry is generally composed of beams, side brackets, and ordinary rollers. The width of the gantry cannot be adjusted freely. Great limitations. Although there are also telescopic frames with adjustable overall width, the existing telescopic frames have low strength and are prone to damage during repeated use. There are many potential safety hazards, and the fine adjustment of width adjustment cannot be realized, and the use effect is not good. ideal. The rollers cannot rotate and move in all directions, let alone realize electronic control, so that the range of movement of the gantry is limited, it cannot adapt to the changing construction environment, and there are s...
