TECHNICAL FIELD

[0001] The utility model relates to conveying equipment technical field, concretely relates to tubular conveying belt and conveyer. BACKGROUND

[0002] At present, the tubular belt conveyor is a special type of belt conveyor, and its characteristic is that the conveying belt forms a closed pipe shape in the running process to wrap the conveyed material. This design not only effectively prevents the leakage of the material in the conveying process, but also reduces the pollution of the external environment to the material, and at the same time reduces the generation of dust and noise, which is very suitable for occasions with high environmental protection requirements.

[0003] The tubular conveying belt is an important component of the tubular belt conveyor, which designs the traditional flat conveying belt into a tubular shape, so as to effectively close the material in the transportation process. This design is particularly suitable for the conveying of bulk materials such as coal, ore and sandstone, which can reduce the scattering and dust pollution of the material in the transportation process, and improve the environmental cleanliness and safety. The tubular conveying belt must ensure a certain transverse stiffness, and the transverse stiffness gradually decreases with the increase of the service life of the equipment. If the transverse stiffness is too small, a stable circular pipe shape cannot be formed in the transportation process, which will cause the belt to collapse and affect the normal operation of the system.

[0035] The tubular conveying belt of the present embodiment is provided with a plurality of rigid pieces 4 in the upper cover layer 2, the rigid pieces 4 being elastically deformed when the belt body is bent into a tubular shape, the rigidity of the belt body being increased by the rigidity of the rigid pieces 4 when being wound into a tubular shape, so that the shape of the circular tube can be better ensured, and the collapse of the tubular belt conveyor is avoided, effectively solving the problem that the transverse rigidity of the tubular conveying belt becomes smaller with the increase of the service life, causing the collapse of the belt and affecting the normal operation of the system.

[0036] In the related art, the limit of the lifting angle of the tubular belt conveyor is 27 degrees, and when the limit angle is exceeded, there is a demand for further increasing the angle when limited by special use conditions.
