Abstract

The utility model provides a belt conveyer which has retractility. The conveying distance can be adjusted at will in a certain range. The belt conveyer achieves the operation of distance adjustment and conveyance by a same conveying belt. The change of the conveying distance is accomplished by the relative movement of a fixed frame and an expansion frame. The conveying length L of the conveyer can follow to change when the expansion frame extends out or retracts. The utility model has the advantages of compact structure, flexible control and flexible and continuous adjustability. The face of the conveying belt is smooth and has no barriers, and the operation in a forward direction and in a backward direction can counterchange at any time.

Description

Expansion belt conveyer

The utility model relates to the belt transporter of transportation such as the case and bag series products, the particularly conveyer of scalable belt.

At present, the general length of band conveyor of various places manufacturing use all is changeless.And the band conveyor that uses under given conditions, then need to have telescopic performance, the band conveyors of the band conveyor of using as warehousing, some loading and unloading usefulness etc. if its fed distance can be adjustable continuously within the specific limits, use just more convenient being suitable for.

The purpose of this utility model will provide a kind of telescopic belt conveyer exactly, and it can be according to using needs, random conversion fed distance.

The utlity model has fixing frame and movable flexible frame, but flexible frame relative fixed frame is made parallel motion, on fixed frame and movable frame, be equipped with separately and lift roller.The fixed frame tail end is provided with a tail wheel; Be provided with a great wheel at flexible frame front end, the rear end relies on support plate that a flower wheel is installed, and a flat belt is through great wheel, and----drive wheel--tail wheel--great wheel forms the closed ring load-transfer device to flower wheel, and drive wheel drives by transmitting actuating device.The stretching out or withdraw of flexible frame, relying on retractable driving device to drive road wheel moves around along the ground rail, road wheel is connected as one by movable leg and flexible frame again, because great wheel and flower wheel connect firmly on same frame, so, when flexible frame moves with respect to fixed frame, the synchronism that can keep this two-wheeled miles of relative movement, the total length of belt conveyor also immobilizes, the actuating device of belt conveyor and the actuating device of flexible frame both can be set up separately respectively, also available same set of actuating device unites two into one, and switches by reversing clutch to drive.The motor that actuating device is used all is equiped with overload protection device, and end position is equiped with limit switch at flexible frame two ends, takes place to prevent contingency.

Stretching of flexible frame, its actuating device can adopt rope traction, rack-and-gear transmission, and type of drive such as feed screw nut and two-way cylinder drive flexible.Flexible frame also can be made into single-ended telescopic or both-end is telescopic, and its maximal dilation length can determine according to actual needs.

The visual actual operating needs of whole frame is made the horizontal fixed formula, inclination fixed type or integral movable type etc.

The utility model is finished the conveying operation by a closed ring load-transfer device, transporting distance can arbitrarily adjust in certain limit, this machine compact conformation, control is flexible, and reliable, the conveying zone face of this machine does not smoothly have barrier, forward and reverse running conversion at any time, therefore, can be adapted to warehouse (as cigarette storehouse, general merchandise storehouse, the warehouse for finished product of washer solvent warehouse for finished product and some case, bag series products) or goods yard usefulness preferably as the specialized equipment of transmitting-receiving, Transhipment Cargo.Simultaneously, also can be used for the place that other has similar conveying requirement.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structure principle chart according to the telescopic belt conveyer of utility model proposition.

Fig. 2 is the structure cutaway view of flower wheel in the utility model (7).

Fig. 3 is the telescopic structure principle chart of both-end that proposes according to utility model.

Fig. 4 is can the whole structure principle chart that moves according to the whole frame of utility model proposition.

Further specify according to concrete device and the service condition that the utility model proposes below in conjunction with accompanying drawing 1 and accompanying drawing 2.

This machine comprises fixed frame (1) and movable flexible frame (3), on them, be fixed with separately and lift roller (2), end in fixed frame and flexible frame is separately installed with a tail wheel (5) and a great wheel (15), the other end of the frame of should stretching is fixed with a flower wheel (7) by two support plates (8), the flat belt (6) of cargo transport usefulness is lifted roller by the tail wheel process, walk around great wheel to flower wheel, walk around the drive wheel (9) below is fixed on behind the flower wheel, be connected to tail wheel formation annular transmission system after walking around drive wheel, driving chain on this drive wheel (10) is connected on the transmission actuating device (11) of driven by motor, on flexible frame, be fixed with movable leg (14), move around on ground rail (16) by road wheel (13) and to realize the conversion of fed distance, on road wheel, be connected with traction steel rope of cable (4), traction steel rope of cable around a track adjusting wheel (17) that plays the fixed pulley effect go up and flexible frame driving device (12) by driven by motor on, in the present embodiment, stretching of flexible frame, adopt rope traction, excuse wheel (15) is fixed on the same flexible frame with flower wheel (7), so when this frame moves with respect to fixed frame, can keep between two-wheeled distance constant, the transmission length of conveyer also changes over L by L thereupon.Below be the basic mechanical design feature of present embodiment:

Wealthy in the frame: 500 millimeters;

Lift roller length: 400 millimeters;

Carry bandwidth: 300 millimeters;

Transport belt speed: 27.6 meters/minute;

Stretching speed: 20.45 meters/minute;

Maximal dilation distance: 2500 millimeters;

Load-transfer device driving power: 2.8KW;

Flexible frame driving power: 1.5KW;

Driving pulley rotating speed: 36.57 rev/mins;

Gear reduction three phase asynchronous motor model:

The bracket height of this machine, installation form and transport distance and collapsing length etc. can be handled flexibly according to customer requirements.

Figure 3 shows that another embodiment.Front and back ends respectively has flexible frame, can make parallel motion with respect to same fixed frame, each flexible frame all is provided with great wheel (15A, 15B) and flower wheel (7A, 7B), with the great wheel of a flat belt (6) around the front and back end, again on separately flower wheel and belt drive wheel (9A, 9B), form osed top annular delivery system, drive forward and backward flexible frame by separately telescopic drive mechanism (identical) and move, realize that the transmission length L changes over L ' with first embodiment.

Figure 4 shows that the 3rd embodiment.Be installing lifting slipping mechanism (18) on fixed frame, have several wheels (19) to contact with ground below the lifting slipping mechanism, make whole frame to move forward and backward, oscilaltion even the axle in the lifting slipping mechanism are done the plane and are rotated.Go up connection digging wheel (20) in great wheel (15), great wheel drives the digging wheel by driving chain (21) and rotates, and carries out digging operation.

The utility model can stretch owing to belt conveyor, the manner novelty, easy to use, its scope of application is very extensive, such as the cargo transfer of station, harbour and the needs of other different occasions, according to this mechanism principle, also can expand using some lifting, sand milling, be coated with on mould and the Robot actions device, as long as more than those variations belong to design range of the present utility model, all be believed to comprise within claims of the present utility model.
