Problems solved by technology

When the lifting distance is relatively short, the power supply line can be dragged to move, and the poor on-site working environment makes the concrete pouring operation extremely unsafe; when the lifting distance is long, the power supply line must be removed first, and then installed after lifting in place Only the power line can be used to open and close the discharge port at the lower end of the concrete hopper, which is cumbersome and greatly reduces the working efficiency

Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] Such as figure 1 and figure 2 As shown, the present invention includes a door hanger 1, an outer frame 2, a hopper 3, a hopper opening and closing device 4, a lever 5 and a hydraulic control device without a power source 6, and the door hanger 1 and the outer frame 2 are all welded by channel steel. The horizontal projection of the outer frame 2 is a rectangle, the upper part of the door hanger 1 is triangular, and the two ends of the vertical bars 11 on both sides of the lower part are respectively hinged with the two sides of the middle part of the outer frame 2. The hopper 3 welded by the steel plate is welded and fixed in the outer frame 2. The left end of the hopper 3 is a material storage box 31 for receiving concrete, and the right end is a pyramid-shaped guide tube 32 which is large inside and small outside and runs through front and back. The right sid...

Abstract

The invention discloses a hydraulic control start-stop concrete hopper, which comprises a door-shaped lifting frame, an outer frame, a hopper, a hopper start-stop device, a lever and a power source-free hydraulic control device. Two ends of the lower part of the door-shaped lifting frame are respectively hinged to two sides of the middle of the outer frame; the hopper is fixed in the outer frame,one end of the hopper is a material containing box, the other end is a front-back cut-through pyramid-shaped guide sleeve, and the hopper start-stop device is arranged on the outer side of the outletend of the pyramid-shaped guide sleeve. The power source-free hydraulic control device comprises a pair of driving oil cylinders, a hopper start-stop oil cylinder, a hydraulic reversing valve and a hydraulic oil tank. The method disclosed by the invention comprises the following steps: (1) enabling the outer frame to stay on the ground completely, (2) enabling the door-shaped lifting frame to leanagainst the upper side of the outer frame, and driving the oil cylinders to absorb oil, and (3) enabling the hopper filled with concrete to be lifted, and enabling the hopper start-stop oil cylinderto drive the hopper start-stop device to open or close through the hydraulic reversing valve. The hydraulic control start-stop concrete hopper is safe in use, the manufacture and use costs are reduced, and the construction efficiency of concrete pouring is improved. The requirement of large-volume concrete pouring is met.

Description

technical field [0001] The invention relates to a concrete pouring hopper required for building construction, in particular to a concrete hopper and a method that does not require a hydraulic power source and can be driven by remote control operation, and belongs to the technical field of building construction. Background technique [0002] When large-volume concrete needs to be poured in civil construction such as bridges, ship locks, dams, and ground buildings, the concrete is usually poured into a horizontally placed hopper, and then the hopper containing the concrete material is lifted vertically to the designated position by a crane, and then opened Concrete pouring is carried out at the discharge opening at the lower end of the hopper. The opening and closing device of the mechanical structure of the lower opening of the hopper in the early days was opened and closed by manual operation. The operator needs to stand on the hopper to operate, and the concrete operator ne...
