With the rapid development of national economy, the belt conveyor is playing an important role in the dock, yard, railway station.However the delivery efficiency is increasingly strict and mobile equipment flexibility is enhanced. Thus we need telescopic amplitude of belt conveyor eagerly. Our SD flexible conveyor is designed and manufactured to solve these problems.

一．Overall performance

Reduce the volume of equipment by characterized with unique telescopic, amplitude and the transverse walk device, it enhances the flexibility of equipment, greatly improving the cloth accuracy and work efficiency, reduce the production cost.

1.Front of the equipment adopts a telescopic frame, it can be adjusted according to user requirements under the material point position to achieve achieve automatic telescopic.

2.The frame is additionally arranged on the luffing mechanism, through adjusting amplitude conveying material blanking height, reduce the unloading dust, avoid the breakage of packing, improve the handling efficiency.

3. Add the walking mechanism at the bottom of the conveyor, greatly enhanced the flexibility of equipment.

4.Equipment delivery, telescopic, amplitude, walking can be a single operation or be synchronized.

5.The frame adopts whole steel plate bending on both sides of the web directly,connected by bolt, which can avoid the welding deformation.It improves the installation accuracy, ensure the equipment delivery, telescopic,amplitude, walking synchronization transmission stability, and the belt off tracking accurately.

6.Bolt connection provides convenience for equipment installation, repair, transfer, transport.

As above picture shows:amplitude frame 1 is the main structure of telescopic amplitude conveyor.It 's realized by turning the telescopic device 2 and hinger 14 .The elastic frame 8 realized by the telescopic drive 2 drive conveyor belt makes the telescopic frame on both sides of the guide rail 7 along the guide wheel 6 telescopic movement. The telescopic movement process of conveying belt by belt to keep constant tension compensation device 11. A walking wheel 13 can drive the flexible lateral movement, tie rail device12 is mainly used to prevent ship sway.

三、Structure type

1. Push rod type structure

Fig 1： Push rod type structure

The structure of push rod type telescopic amplitude conveyor is compact, the captain is within 20 meters,can achieve maximum extension length of 7 meters, the amplitude range of 0 ° to 30 °. The telescopic,amplitude, walking are more flexible, generally used to vehicle, ship, train loading.

Fig 4 Vehicle type structure

The conveyor can be placed in various types of truck chassis. After the basic arm is a major part of the conveyor, drive the front and rear telescopic boom as amplitude movement. The front conveying part frame amplitude range of - 16 ° ~ + 21 °, the rear conveying part frame amplitude range of 0 ~ 90 °. The front and rear of the telescopic boom are consists of a roller and can drive the tape to do telescopic movement.The front telescopic arm telescopic range is 0 ~ 7.3 meters, the rear of the telescopic expansion in the range of 0 ~ 2 meters. The basic arm and a telescopic arm bottom adopts connecting rod tensioning device,so the linear degree is adjustable.The front and rear luffing cylinder is the power mechanism of conveyor frame.Realize the luffing movement through the extension of the oil cylinder. Telescopic motor by tightening or loosening steel wire rope and telescopic arm make telescopic movement. The front and rear transmission part together with a conveyor belt of diaphragm and guide strip belt, to prevent materials from falling and the deviation of the belt. Conveyor support for ± 120 ° rotation, which can adjust the discharging point position. Idler form has two kinds, flat and trough roller, the control room is the control room for people to operate. The conveyor's flexibility used in food, chemical industry, building, docks, stations and storage areas.

5.Multiple sections of telescopic structure

1.The first basic frame 2.The second sections of telescopic rack 3.The third telescopic rack 4.The fourth telescopic rack

5.The fifth telescopic rack

Multiple sections of telescopic belt conveyor is mainly used for trucks, trailers and container cargo' s unloading .Telescopic conveyor can be easily extended to any length, improve work efficiency , convenient and easy to operate. Applicable to conveyor carton, package and bulk materials and any other things.
