产品说明 Product Description
LDY type metallurgical electric single beam crane
Product Brief
One, overview
Installation, and use of this manual applies to LDY type metallurgical electric single girder crane for maintenance, installation, operation and maintenance personnel.
The 1 main purposes
LDY type metallurgical electric single girder crane (hereinafter referred to as the crane) is according to the standard of JB/T1306-2008 and meet the quality inspection office "375 Hao Wen
Space transportation tools supporting the use of component design and YHII type electric hoist, the main role is to batch, cycle work, by lifting
Hook or other fetching device timely and rapidly complete displacement lifting weights required for metallurgy in the production process, is the metallurgical and modern industrial enterprises
Casting sites important for improving labor productivity tools and equipment.
2 scope of application
LDY type crane is suitable for work in the level of A6, the working environment temperature less than 60 DEG C, relative humidity less than 85%, with an altitude below 2000m, no
Corrosive environment under the working conditions.
Environmental conditions 3
(1) crane for three-phase AC, rated frequency 50Hz, rated voltage of 380V (such as power supply voltage, frequency and this shall not
At the same time, shall indicate the power use of voltage and frequency in order), motor and electrical control equipment allows the voltage fluctuation of the upper limit of the rated power
+10% voltage lower limit (peak current), rated voltage -15%. Voltage loss in internal crane 5%.
(2) crane working environment: temperature is less than or equal to 60 DEG C, humidity is less than or equal to 85%, with an altitude below 2000m, no fire, explosion, corrosive medium.
4 noise
The crane in non airtight workshop, no other noise interference and the situation of lifting height of not less than 5m, measured on the ground, the weight of Q
Less than or equal to 5T when the noise is not greater than 85 dB (A), weight Q is more than or equal to 5T when the noise is not greater than 90 dB (A)
Parameters of structure and properties of two, crane
The crane structure mainly consists of three parts: bridge, metallurgy electric hoist and electrical system (see Figure 2 and random graph).
Tray for supporting and longitudinal moving load, composed of the metal structure and operation mechanism. Metal structure comprises a main beam, end beam and main, Duan Lianglian
Then the three part. The running mechanism is composed of a driving device, transmission device, a braking device and a wheel group is composed of four parts. Metallurgical electric hoist lifting and cross to bear
To moving load. The electrical system consists of a main circuit and a control circuit.
1 Bridge
Pressed girder by U type channel steel and I-shaped steel is welded into solid web beam or plate welding box beam. End beam for U type channel steel welded into group
Shaped structure, the main, the end beams by bolts with flange connection structure or shear type structure, convenient installation, convenient transportation and storage.
2 operating mechanism
Run institutions were driven by the form (see Figure 1), driving, braking by conical rotor motor to complete, its advantage is able to reduce the wheels
Skew deviation caused by gnawing rail wear, not easy to appear the wheel rail climbing out of failure.
Speed: the ground operation is generally 20, 30 m/min. The general situation in terms of single speed manufacturing, if users need other speed regulation methods, should be in the
Negotiate a contract signed before and design departments can use and shall be specified in the contract.

Lifting mechanism 3
Crane equipped with two independent brake - brakes and safety brakes (i.e. double brake) metallurgical electric gourd and overload limiter
Lu composed of hoisting mechanism, can lift lifting weights, and along the beam transverse movement.
4 electrical system
Metallurgical electric hoist lifting operation of the motor used starting conical rotor motor torque is larger, in order to adapt to the crane intermittent work frequently
Direct start. In order to adapt to the more than 40 degrees Celsius temperature environment by the motor insulation grade H, and adopts the high temperature resistant cable.
Crane manipulation by pressing a button switch (flashlight door), so that the contact is switched on or off the power of the motor contactor. The main circuit and control
Business loop electrical fewer components, simple circuit, convenient use and maintenance.
Using insulation protection measures in the motor and other electric equipment outer.
5 forms of manipulation
(1) ground handling: the operating personnel on the ground to control the flashlight door button, control of crane load operation. Crane running speed is less than or equal to 30m/ min.
(2) remote control: the operating personnel handheld remote control crane lifting load operation.
Note: This product is recommended to use remote control mode of operation, in order to protect the safety of personnel.
