Concrete mixing and filling pump truck for mines

Abstract

The invention discloses a concrete mixing and filling pump truck for mines. In the invention, a dry concrete mixed material feeder, a concrete mixer, a water supply system, a finished concrete conveying system, a hydraulic power system, a control system are all installed on a frame; rail wheels matched with rails are arranged at the lower end of the frame, and four support oil cylinders are arranged at the four corners of the frame. The mixer is a continuous double horizontal spindle concrete mixer used for realizing the continuous operation of concrete from dry material conveying to water supplying, mixing and conveying. The concrete mixing and filling pump truck for mines is small and flexible, does not need to be dissembled or assembled when moved in surface and underground operation, can work and be moved at anytime during working on the rails, and occupies small area in construction.

Description

Technical field [0001] The invention relates to a mining equipment, in particular to a concrete mixing and filling equipment with a small volume and flexible movement used in the construction of a mine tunnel and a coal mine underground concrete building. Background technique [0002] With the development of society and economy, the construction of concrete buildings is becoming more and more complicated. For example, pillarless mining techniques such as leaving roadways along goafs in coal mines and backfilling mining require concrete filling construction. Construction equipment that is small in size, flexible in movement, convenient in installation, and capable of mixing and conveying concrete is required. [0003] The current mining concrete equipment is a simple combination of existing concrete pumps and gap mixers. The equipment is huge, with a total installation height of 3.5 to 4 meters. It can only be fixed and installed. Sometimes the space needs to be expanded during inst...

AI Technical Summary

Problems solved by technology

[0003] At present, the mining concrete equipment is a simple combination product of the existing concrete delivery pump and the gap mixer. The equipment is huge, and the total installation height is 3.5 to 4 meters. It can only be installed and constructed. Sometimes the space needs to be expanded during installation and cannot be moved. , it must be reinstalled when moving; some manufacturers also disassemble the concrete delivery pump into two parts, the delivery unit and the power unit, and the height is reduced, but the total length of the installation is too long, with a length of 8 to 9 meters, or even more than 15 meters, which is still inconvenient to install. When moving, it still needs to be reinstalled; and the gap mixer needs to measure and proportion the supply of materials and water. Due to the limitation of underground space, it is impossible to install these equipments, which leads to difficulties in underground concrete construction and heavy workload.

The disadvantage of the equipment is that it can only be used fixedly. When going up and down the well and moving, it needs to be disassembled, combined and installed again, and the operation equipment is cumbersome, etc.
