自動混凝土攪拌機操縱機構設計分析

自動混凝土攪拌機使用過程中的大部分時間罐體都在轉動,操縱機構直接控制罐體的進料、攪拌、攪動、出料、停轉等工作狀態。下面來分析自動混凝土攪拌機操縱機構設計吧。
The tank body rotates most of the time during the use of the automatic concrete mixer, and the operating mechanism directly controls the feeding, mixing, stirring, discharging, stopping and other working conditions of the tank body. Now let's analyze the control mechanism design of automatic concrete mixer.
一、操縱機構的形式
1、 Form of control mechanism
操縱機構根據其連接方式,一般有三種形式
The operating mechanism generally has three forms according to its connection mode
(1)機械連桿方式
(1) Mechanical linkage mode
使用連桿連接到整車后端的兩個連動的操縱手柄,可以從車輛的兩面操作。此種連接方式可靠,結構比較復雜,易于維護。
Two linked joysticks connected to the rear end of the vehicle can be operated from both sides of the vehicle. This connection mode is reliable, complex in structure and easy to maintain.
(2)軟軸方式
(2) Flexible shaft mode
使用軟軸連接到整車后端的一個操縱手柄,僅能從車輛的單面操作。此種操縱機構相對簡單,比較美觀,但軟軸一旦損壞就無法修復。因此攪拌車使用這種操縱方式并不多見。
A joystick connected to the rear end of the vehicle with a flexible shaft can only be operated from one side of the vehicle. This kind of control mechanism is relatively simple and beautiful, but once the flexible shaft is damaged, it cannot be repaired. Therefore, it is rare to use this kind of operation mode for mixer trucks.
(3)電控方式
(3) Electric control mode
使用電動方式調節油泵轉向,線路元件損壞,非專門的人員一般難以修復。攪拌車屬于工程車輛,運行工況較復雜,在國內很少使用。
If the oil pump steering is adjusted electrically, the circuit components are damaged, and it is generally difficult for non specialized personnel to repair. Mixers are engineering vehicles with complex operating conditions, which are rarely used in China.

二、設計時應注意的問題
2、 Matters needing attention in design
目前攪拌車主要使用的機械連桿式操作機構。下面主要針對連桿式操縱機構的設計進行分析。
At present, the mechanical linkage type operating mechanism is mainly used for mixer trucks. The following mainly analyzes the design of the linkage control mechanism.
操縱機構的功能性要求
Functional requirements of control mechanism
操縱機構要求從駕駛內和整車后部均可以靈活操縱。操縱機構需要控制上裝的油泵和發動機的油門。操縱機構通過控制油泵的斜盤拉桿調節罐體的正反轉。由于油泵的斜盤拉桿的角度和作用力不同,這就要求對不同的油泵設計不同的放大機構。
The control mechanism is required to be flexible from the inside of the driver and the rear of the vehicle. The operating mechanism needs to control the upper mounted oil pump and the accelerator of the engine. The operating mechanism regulates the forward and reverse rotation of the tank body by controlling the swashplate pull rod of the oil pump. Because the angle and force of the swashplate pull rod of the oil pump are different, different magnifying mechanisms are required for different oil pumps.
操縱機構的可靠性要求
Reliability requirements for operating mechanism
攪拌車在運行過程中需要保證罐體的正向運轉,但攪拌車運行的工況一般較差,操縱手柄的振動容易導致油泵的斜盤拉桿復位,罐體可能會出現停轉或者反轉卸料現象。司機在行車時往往注意不到罐體的運轉情況,可設計駕駛室內的操縱手柄鎖緊機構來確保罐體的正常轉動。
During the operation of the mixer, it is necessary to ensure the tank body to run in the positive direction, but the working condition of the mixer is generally poor. The vibration of the operating handle is easy to cause the reset of the swashplate pull rod of the oil pump, and the tank body may stop or reverse unloading. When driving, the driver often cannot notice the operation of the tank, so the locking mechanism of the joystick in the cab can be designed to ensure the normal rotation of the tank.
操縱機構的可維護性
Maintainability of control mechanism
操縱機構難免損壞,要方便維護,及時排除故障。
The operating mechanism is inevitably damaged, which shall be convenient for maintenance and timely troubleshooting.
對攪拌車罐體的操作有多種方式,但原理基本相同。由于攪拌車工作環境比較惡劣,在實現功能性的同時,關鍵要提高操縱機構的可靠性和可維護性。更多相關內容就來我們網站http://www.dinghelaw.com咨詢了解吧。
There are many ways to operate the tank of the mixer truck, but the principle is basically the same. Due to the harsh working environment of the mixer, it is critical to improve the reliability and maintainability of the operating mechanism while realizing the functionality.
