Problems solved by technology

This judgment method is difficult to ensure that the operation of the quick-setting agent pump is stopped in time, and it is easy to cause misjudgment, which affects the progress and quality of the work, and has high requirements for the professional quality of the user.
In addition, since the user needs to be close to the quick-setting agent pump that may be in an abnormal working state, the safety hazard of the user is increased, resulting in casualties

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] figure 1 The structure of the quick-setting agent pump protection device (hereinafter referred to as the protection device) is schematically shown. The protection device includes a collection component, a controller 20 and an actuator 30 . Wherein, the collection component can collect the state of the quick-setting agent pump 100 (such as temperature, flow rate, flow rate, internal pressure, etc.), and generate a working state signal. The controller 20 receives the working status signal and monitors it. When the working state of the quick-setting agent pump 100 changes, the protection device can instruct the actuator to adjust the working state of the quick-setting agent pump according to the monitoring result.

[0025] The preset working state information is pre-stored in the controller 20, and the preset working state information is the ideal working state infor...

Abstract

The invention relates to an accelerating agent pump protection device and a vehicle-mounted type wet spraying machine. The accelerating agent pump protection device comprises a collecting assembly, a controller and an actuator, wherein the collecting assembly is used for collecting a working state of an accelerating agent pump and generating a working state signal; the controller is used for monitoring the working state of the accelerating agent pump according to the working state signal; the actuator is used for controlling the operation of the accelerating agent pump according to the working state, measured by the controller, of the accelerating agent pump. The vehicle-mounted type wet spraying machine comprises the accelerating agent pump and the accelerating agent pump protection device. According to the accelerating agent pump protection device disclosed by the invention, the working state of the accelerating agent pump can be automatically changed.

Description

technical field [0001] The invention relates to the field of tunnel engineering, in particular to a protective device for an accelerator pump. The invention also relates to a vehicle-mounted wet spraying machine including the quick-setting agent protection device. Background technique [0002] In recent years, with the country's great investment in infrastructure, vehicle-mounted wet spraying machines have been used as concrete conveying equipment in domestic railway (highway) tunnels, mine shafts, culverts, rock and soil slopes, hydropower projects, military projects, large-scale It is widely used in foundation, subway and municipal construction. [0003] Vehicle-mounted wet spraying machines are usually used in outdoor operations or mobile operations, so their loading capacity for accelerators is very limited, and they cannot be replenished in a timely manner. Therefore, during the working process of the vehicle-mounted wet spraying machine, the accelerator pump often ha...
