Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1 and 2, the secondary constructional column pump of the present disclosure includes a frame 1, a slide table, two material cylinders 3, a hopper 4, and a discharge pipe 5.

The sliding table is arranged on the frame 1, and is provided with a fixed seat 201 fixed with the frame 1, a sliding plate 202 horizontally and slidably connected to the fixed seat 201, and a driving part 203 for driving the sliding plate 202 to reciprocate and move transversely, and the sliding plate 202 is provided with two transversely arranged mounting holes. The material cylinder 3 is vertically arranged, the upper end of the material cylinder is fixed with the corresponding mounting hole, a piston 301 is arranged in the material cylinder 3, and the bottom of the piston 301 is provided with a second driving part 302 for driving the piston to reciprocate up and down. The hopper 4 is fixed to the sliding plate 202 and has a discharge opening at the bottom thereof corresponding to the two cylinders 3. The discharge pipe 5 is vertically fixed on the frame 1, and the lower end of the discharge pipe extends into the hopper 4 and can be aligned and communicated with any material cylinder 3.

The first driving part 203 and the second driving part 302 are hydraulic cylinders, the hydraulic cylinders are connected with a hydraulic system, and the operation is more stable and reliable by adopting a hydraulic driving mode. In addition, a pipeline for connecting the hydraulic system and the hydraulic cylinder is provided with a hydraulic bag for storing hydraulic pressure, a pressure increasing valve and the like, so that the purpose of increasing pressure is achieved, and the driving reaction is more sensitive.

When the secondary constructional column pump works, slurry such as concrete is injected into the hopper 4, the pistons 301 in the two material cylinders 3 are discharged under the drive control of the second drive part 302, one piston 301 sucks the slurry downwards into the cylinder barrel, the other piston 301 pushes the slurry upwards out of the cylinder barrel, the discharge pipe 5 is in butt joint with the two cylinder barrels in turn under the drive control of the first drive part 203, and the cylinder barrel in butt joint with the discharge pipe 5 is in a working state of pushing the slurry upwards. The slurry is discharged from the hopper 4 to the casting site via the discharge pipe 5.

This secondary structure post pump has abandoned current S pipe valve, has reduced the weight and the energy consumption of equipment, and it is more convenient to remove the operation, and the straight tube is compared in the return bend preparation simpler. The material cylinders 3 and the discharge pipe 5 are arranged up and down, and the two material cylinders 3 are in butt joint with the discharge pipe 5 in turn through the integral transverse movement of the two material cylinders 3, so that the continuous conveying of concrete is realized. The passageway of the guide in this structure is vertical setting, and the adhesion material is less and be convenient for wash.

In addition, because the slurry is mixed with stones, in order to avoid the situation that the end part of the discharge pipe 5 collides and is worn by the stones in the relative transverse moving process to generate gaps, and slurry leakage is caused, a wear-resistant layer made of alloy is arranged at the butt joint of the discharge pipe 5 and the discharge port, and the wear-resistant layer is arranged at the lower end of the discharge pipe 5 and the upper end surface of the discharge port.

The sliding connection between the sliding plate 202 and the fixed base 201 may be formed by a sliding rail on the fixed base 201, a sliding block fastened with the sliding rail on the sliding plate 202, and the sliding rail may be shaped like a T or a circle, so that the sliding rail and the sliding block are vertically limited after being matched.
