DETAILED DESCRIPTION​

[0019] In order to more clearly illustrate the technical scheme of the embodiments of the present application, the drawings needed in the embodiments will be briefly introduced as follows. Obviously, the drawings in the following description are some embodiments of the present application, and other drawings can also be obtained by those skilled in the art without creative labor on the basis of these drawings.

[0020] Please refer to Figures 1 to 5 A kind of without supporting roller hanging belt conveyor 10, including drive part 20, transmission roller 30, tensioning mechanism 40, conveying belt 50, pull belt device 60, rack, the rotating shaft of drive part 20 is connected with transmission roller 30, to drive transmission roller 30 rotation, transmission roller 30 is located at the head of without supporting roller hanging belt conveyor 10, tensioning mechanism 40 is located at the tail of without supporting roller hanging belt conveyor 10, tensioning mechanism 40 is equipped with tensioning wheel to tighten conveying belt 50, conveying belt 50 is connected with transmission roller 30, tensioning mechanism 40 is set, the left side and right side of conveying belt 50 are connected with pull belt device 60, the upper end of pull belt device 60 is connected with rack, conveying belt 50 is hung on rack by pull belt device 60, the pull belt device 60 includes guide wheel assembly 601, load rope 602, pull assembly 603, the guide wheel assembly 601 is located at the two sides of rack and is fixedly connected with rack, load rope 602 is annular and overlaps with guide wheel assembly 601, pull assembly 603 is evenly distributed on load rope 602, one end of pull assembly 603 is fixedly connected with load rope 602, the other end of pull assembly 603 is fixedly connected with conveying belt 50.

[0021] The drive part 20 of the present application is used to provide power for the transmission roller, and then drive the conveying belt 50 to rotate. The tensioning mechanism 40 is used to adjust the tightness of the conveying belt 50. The tensioning mechanism 40 is a conventional tensioning mechanism 40 used for the conveying belt 50, which mainly adjusts the tightness of the conveying belt 50 by adjusting the horizontal distance between the tensioning wheel and the drive part 20. The pull belt device 60 is used to suspend the conveying belt 50, i.e. the pull belt device 60 bears the weight from the conveying belt 50, and the conveying belt 50 does not contact other components. Compared with the supporting roller, the contact area of the conveying belt 50 is significantly reduced, and therefore the energy consumption caused by the friction of the conveying belt 50 is also significantly reduced. The load rope 602 of the pull belt device 60 bears the weight from the conveying belt 50 and acts on the guide wheel assembly 601. The steel wire rope is relatively thin and is rolling friction, so the resistance it receives is also small, which can reduce energy consumption.

[0022] In a preferred embodiment, the guide wheel assembly 601 comprises two main guide wheels 6011 coaxial with the transmission roller 30 or the tensioning wheel, and a plurality of auxiliary guide wheels 6012, the load bearing rope 602 being connected to the main guide wheels 6011 in a sleeved manner, and the auxiliary guide wheels 6012 being arranged in two layers on the frame between the two main guide wheels 6011 and being overlapped with the load bearing rope 602.

[0023] The main guide wheels 6011 are mainly used for tensioning the load bearing rope 602 so as to keep the load bearing rope 602 as horizontal as possible. The auxiliary guide wheels 6012 are mainly used for dispersing the weight of the load bearing rope 602. The upper auxiliary guide wheels 6012 bear the weight of the upper load bearing rope 602, and the lower auxiliary guide wheels 6012 bear the weight of the lower load bearing rope 602.

[0024] In a preferred embodiment, the pulling assembly 603 comprises a sleeve 6031, a plurality of pulling ropes 6032, and a hanging ear 6033, the sleeve 6031 being connected to the load bearing rope 602 in a sleeved manner, one end of the pulling rope 6032 being connected to the sleeve 6031, the other end of the pulling rope 6032 being connected to the hanging ear 6033, and the hanging ear 6033 being fixedly connected to the conveying belt 50.

[0025] The sleeve 6031 clamps the load bearing rope 602 and the pulling assembly 603, so that the pulling assembly 603 and the load bearing rope 602 move synchronously. The pulling ropes 6032 disperse the tension, and at the same time, when one of the pulling ropes 6032 is disconnected, the load bearing rope 602 and the conveying belt 50 will not be disconnected, so as to avoid the shutdown of the conveyor. During the maintenance process, when the disconnected pulling rope is found, it can be replaced in time, so as to improve the conveying efficiency of the conveyor.

[0026] In a preferred embodiment, the load bearing rope 602 is a steel wire rope.

[0027] In a preferred embodiment, the frame comprises a plurality of vertical supports, the vertical supports being evenly distributed between the driving part 20 and the tensioning mechanism 40, and the auxiliary guide wheels 6012 being arranged on the vertical supports and being distributed in two layers.

[0028] During the rotation of the load bearing rope 602, the pulling assembly 603 will interfere with the edge of the guide wheel, so as to cause the abrasion of the pulling assembly 603. Therefore, in a preferred embodiment, the wheel disc of the main guide wheel 6011 is in the form of a gear tooth, so as to avoid the interference between the pulling assembly 603 and the main guide wheel 6011. When the pulling assembly 603 passes through the wheel disc, it will pass through the gear gap, so as to avoid the interference.

[0029] Similarly, in a preferred embodiment, the wheel disc of the auxiliary guide wheel 6012 is in the form of a gear tooth, so as to avoid the interference between the pulling assembly 603 and the auxiliary guide wheel 6012.

[0030] In a preferred embodiment, the driving part 20 comprises a motor support 201, a driving motor 202, and a coupling 203, the upper end of the motor support 201 is fixedly connected with the driving motor 202, the rotating shaft of the driving motor 202 is connected with one end of the coupling 203, and the other end of the coupling 203 is fixedly connected with the rotating shaft of the transmission drum.

[0031] The above only discloses preferred embodiments of the present application, and of course cannot limit the scope of the present application, and those skilled in the art can understand that all or part of the above-mentioned embodiments can be implemented, and equivalent changes made according to the claims of the present application still belong to the scope of the present application.
