Concrete pump with lift type hopper fence

Abstract

The invention discloses a concrete pump with a lift type hopper fence for thoroughly solving the concrete accumulation problem. The concrete pump comprises a concrete stirring device, a hopper, a fence and a frame; a mounting frame is fixed on one side of the frame; a lift driving device is fixed on the mounting frame; a mounting plate is fixed at the lower end of a lifting rod of the lift driving device; a vibration device is fixed on the mounting plate; the vibration device includes a pneumatic vibrator and a vibrator clamping device; multiple guide rod passing holes are formed in the vibrator clamping device; clamping device guide rods are slidingly matched in the guide rod passing holes; the upper and lower extension ends of the clamping device guide rods are respectively coated with compression springs; and the lower ends of the clamping device guide rods are fixedly connected with the mounting plate.

Description

technical field [0001] The invention relates to the field of concrete machinery, in particular to a concrete pump with a lifting hopper fence. Background technique [0002] Concrete pump is a kind of high-efficiency concrete conveying machinery, which is widely used in high-rise buildings, coal mines, mines, tunnels, railways, highways, bridges, ports, water conservancy, electric power, national defense projects and other concrete projects. It continuously presses the concrete to the pouring site through the pipeline, and has good maneuverability. [0003] When the concrete pump is pumping concrete, the concrete delivery tanker needs to continuously dump the concrete into the concrete pump hopper. In order to prevent large materials from entering the hopper and to ensure safe operation, a grid structure fence is generally designed on the upper surface of the hopper. The main The function is to prevent the excessive material in the concrete mortar from entering the hopper, a...

Problems solved by technology

This fence vibration method improves work efficiency and reduces potential safety hazards, but due to the need to add additional vibration sources and some additional accessories to the concrete pump, the cost of the concrete pump increases, which is not conducive to market promotion; and the concrete pump The working environment is harsh, and the newly added vibration source increases the failure points of the equipment to a certain extent, and its reliability is reduced; in addition, the space above the hopper fence is limited, which brings difficulties to the design of the concrete pump; Inconvenient maintenance, which in turn increases the maintenance cost o...
