Reed has double speed：16/1.6 (m/min), corresponding to the lifting velocity 2.67/0.267 (m/min) of rake arms point of suspension.Arm support is transferred
When descending at slow speed, before scraper need to transpose work, rake arms ability fast lifting.It is to ensure that rake arms and steel wire rope keep good work
Make state, multiple protection devices need to be set.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, there is provided a kind of new rake arms angle show and
Protection device.
In order to reach the purpose of this utility model, technical scheme is as follows：
A kind of new rake arms angle shows and protection device is it is characterised in that include electronic type inclinometer, rake arms lifting is moved
Make that double-speed motor, upper and lower pull bar be spacing, broken step chain device, pull switch, PLC control system and touch display screen, described electronics
, in the root of rake arms, for real-time measurement rake arms operation angle, rake arms lifting action double-speed motor is in rake arms root for formula inclinometer
Underface, upper and lower pull bar spacing in rake arms lifting action double-speed motor both sides, broken step chain device, pull switch are in rake arms lifting action
On the operating platform at double-speed motor rear, PLC control system and touch display screen are also at rake arms lifting action double-speed motor rear
Operating platform on, and be electrically connected between the two.
Preferably, during described electronic type inclinometer horizontal level, its count value is zero, passes through steel by calculating rake arms
The angle of cord lifting, can easily measure rake arms operation angle, and PLC control system device is communicated by RS485, from
Dynamic detection rake arms operation angle and then be sent to touch display screen and show.
Preferably, described PLC control system is controlled to rake arms lifting, and PLC control system combines upper and lower pull bar limit
Position, broken step chain device, pull switch play soft spacing, drawstring protection switch the defencive function of angle that spacing, PLC is arranged up and down
Effect.
This utility model has the advantage that：
Display rake arms angle is more accurate, shows in real time, and reflection is sensitiveer, occurs sending acousto-optic warning during emergency
Unit, operation and repair and maintenance personnel can be checked in time to associated components and processed, it is to avoid substantial equipment fault, and to maintenance
Provide important reference frame, save maintenance time.
Brief description
Fig. 1 be this utility model rake arms angle show and protection device structural representation.
Wherein 1. screw(-type) feeders, 2. rustless steel hopper, 3.PLC controller, 4. high-precision weighing sensor, 5. weighing instrument
Table
Specific embodiment
With reference to embodiment, this utility model is further described, but protection domain of the present utility model not only office
It is limited to embodiment.
In conjunction with shown in Fig. 1, a kind of new rake arms angle shows and protection device is it is characterised in that include electronic type angle
Instrument 1, rake arms lifting action double-speed motor 2, upper and lower pull bar are spacing 3, broken step chain device 4, pull switch 5, PLC control system and touch
Display screen 6, described electronic type inclinometer 1, in the root of rake arms, measures rake arms operation angle, rake arms lifting action for real-time
Double-speed motor 2 immediately below rake arms root, for by rake arms lifting and decline.
, in rake arms lifting action double-speed motor 2 both sides, broken step chain device 4, pull switch 5 are in rake arms liter for pull bar spacing 3 up and down
On the operating platform at fall action double-speed motor 2 rear, PLC control system 6 and touch display screen 7 are also in rake arms lifting action double speed
On the operating platform at motor rear, and it is electrically connected between the two.
Preferably, during described electronic type inclinometer 1 horizontal level, its count value is zero, passes through steel by calculating rake arms
The angle of cord lifting, can easily measure rake arms operation angle, and PLC control system device is communicated by RS485, from
