Problems solved by technology

[0003]However, this highly integrated control scheme also causes the biggest disadvantage to users, that is, the controller must be free from any faults
Once the controller fails, the concrete pump truck will stop running, which will inevitably cause the concrete to solidify and dry in the distribution pipe, causing economic losses to the user

Embodiment Construction

[0019] Attached below figure 1 ~ attached Figure 7 The principle and implementation method of the present invention will be described in detail.

[0020] An emergency pumping system composed of a manual operation device, a central operator and an emergency control unit, including: a manual operation device 14, a central operator 10 and an emergency control unit. It is characterized in that: the manual operation device 14 is connected to the central operator 10 through a wire harness, and the central operator 10 is connected to the emergency control unit through a wire harness 4 .

[0021] Such as figure 2 As shown, the manual operation device 14 is composed of the operation box 1, the S28 two-position self-locking toggle switch 3, the S29 three-position self-locking toggle switch 2, the wiring harness 4, and the 7-hole connector 5. Its schematic diagram is as follows image 3 shown. After fixing the switch, connect one end of the wiring harness 4 with the S28 two-positi...

Abstract

An emergency pumping system composed of a manual operation device, a central operator and an emergency control unit comprises the manual operation device, the central operator and the emergency control unit. The manual operation device is connected with the central operator through a wire harness, and the central operator is connected with the emergency control unit through a wire harness. The manual operation device comprises an operation box, a two-position self-locking toggle switch, a three-position self-locking toggle switch, a seven-hole plugging piece and a wire harness. The operation box has the function of being connected with the central operator. The central operator comprises a pumping indicator lamp, an emergency operation switch and an emergency interface connected with the manual operation device. The central operator is a terminal of the operation of an entire concrete pump truck, and is the centralized management part of the operation of the concrete pump truck. The emergency control unit comprises four relays and an engine rotating speed interface. The emergency pumping system has the advantages of being reasonable in design, convenient to operate, capable of quickly solving the problem that concrete in a pipeline cannot be pumped by the concrete pump truck due to faults.

Description

Technical field: [0001] The invention belongs to the technical field of special vehicles, and in particular relates to an emergency pumping system composed of a manual operation device, a central operator and an emergency control unit. Background technique: [0002] The concrete pump truck is a special vehicle that integrates the pumping mechanism for pumping concrete and the boom for distributing materials on the chassis of the car. When working, the power of the diesel engine in the chassis of the car is used to transmit the power to the hydraulic pump through the transfer case, and then drive the concrete pumping mechanism and the boom system. The pumping system pressurizes the concrete in the hopper into the pipeline, and the pipeline is attached to it. On the arm frame, the arm frame can be moved so that the concrete pumped by the pumping mechanism can be directly sent to the pouring point of the project. Concrete pump truck is a vehicle with highly coordinated structu...
