Problems solved by technology

[0006] It can be seen that neither the overall side-opening structure nor the folded side-opening structure, nor the sliding flat-push retractable tarpaulin structure can be directly applied to the conditions of high temperature, strong ultraviolet rays, high wind speed, and frequent rainfall at hydropower construction sites. Good job of transporting concrete

Embodiment 1

[0031] A sunshade and rainproof device for a concrete dump truck, which consists of a mechanical transmission system, a hydraulic system, an electrical control system and a compartment cover. The hydraulic system includes an oil pump, an oil cylinder, a power unit and a reversing valve. The described The oil cylinder is set on the carriage, and the power unit and the reversing valve control the oil cylinder to perform reciprocating linear motion; the mechanical transmission system is composed of a rotating arm, a driving arm and a driven arm, and the rotating arm is rotatably arranged in the carriage On the upper edge; the active arm and the driven arm are meshed with each other, and the centers of the active arm and the driven arm are respectively hinged on the carriage; one end of the oil cylinder is hinged on the carriage at the lower part of the active arm and the driven arm, and the telescopic end of the oil cylinder is connected with the carriage. The secondary long teeth...

Abstract

The invention belongs to the technical filed of machines, and particularly relates to a sun-shading rain-proof device used for a concrete dump truck. The sun-shading rain-proof device used for the concrete dump truck is composed of a mechanical transmission system, a hydraulic system, an electrical control system and a carriage cover. The device can control the temperature in the process of transporting casting concrete used for dams and can shield wind and rain to prevent the concrete from being contaminated; an inner container layer is additionally arranged in a carriage of the dump truck, the position between the inner container and the carriage is filled with a refrigerator foaming agent, the heat preservation effect can be achieved on the periphery of the side surface and the top surface of the carriage, and therefore the effect of preserving the temperature of the concrete in the transporting process is better.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a sunshade and rainproof device for a concrete dump truck. Background technique [0002] The construction site of some hydropower stations has high temperature, strong ultraviolet rays, high wind speed and frequent rainfall, such as Baihetan Hydropower Station. In order to ensure the quality of the project, in view of the large temperature changes during the transportation of concrete and the impact on the quality of the dam pouring construction, the concrete transportation dump truck must be sealed to meet the temperature control requirements of the concrete transportation project. The addition of a fully enclosed transport device to the dump truck can also achieve functions such as windproof, rainproof, heat preservation, and prevention of spilling, dripping, and dust pollution. [0003] At present, there are two types of opening and closing forms of t...
