Description

Technical Field

[0001] This utility model relates to the field of transportation machinery technology, specifically to a belt conveyor conveying device. Background Technology

[0002] Tubular conveyor belts, also known as flexible hose conveyor belts or pipe conveyor belts, are typically constructed by mechanical means to form a closed tube within the transport area. Tubular belt conveyors can enclose materials for transport, significantly reducing dust and spillage during transport and at transfer points, thus minimizing environmental pollution.

[0003] Chinese patent CN1109638C discloses a flexible belt conveyor and its driving device. This device uses a flexible belt conveyor hoisting installation method, but lacks an upper pressure roller device, which easily leads to upward deviation. It cannot generate a corresponding forward tilt angle between the driving rollers on both sides and the conveyor belt's running direction, thus failing to counteract the free sag of the conveyor belt during operation, reducing the conveyor belt's conveying energy, and increasing the risk of the conveyor belt falling off.

[0004] Chinese patent CN110745455B discloses a suspended tubular belt conveyor device. This device uses a relative motion between the lifting clamp and the track, which causes significant damage to the track during long-term operation and results in high overall maintenance costs.

[0005] It is evident that current belt conveyor systems suffer from the following technical problems: 1. The lack of pressure roller assembly fails to effectively limit conveyor belt position deviation during operation, affecting the stability of the conveyor belt; 2. The suspension roller assembly remains perpendicular to the conveyor belt's running direction, failing to overcome the gravity generated by the conveyor belt and the material it carries, resulting in conveyor belt sagging, reduced conveyor belt capacity, and increased risk of belt drop. In actual operation, the manpower and costs required for a single belt drop are substantial. Utility Model Content

[0007] This utility model provides the following technical solution:

[0008] A belt conveyor conveying device, characterized in that it includes a conveyor belt mounting pipe, a conveyor belt, a fixing frame, two hanging roller assemblies, and a limiting pressure roller assembly; the fixing frame is fixed on the conveyor belt mounting pipe; the two hanging roller assemblies are fixed on the left and right sides of the fixing frame and are symmetrically distributed, the two hanging roller assemblies forming a certain included angle α, the conveyor belt passes through the hanging roller assemblies on the left and right sides and forms a triangular head above the hanging roller assemblies, the included angle α matches the triangular head of the conveyor belt, and the limiting pressure roller assembly is fixed on the fixing frame and located above the triangular head.

[0009] Furthermore, the fixing frame includes an upper fixing frame and a lower fixing frame, which are fixed to the conveyor belt mounting pipe by bolts.

[0010] Furthermore, the included angle α is between 35° and 70°.

[0011] Furthermore, the suspension roller assembly includes a suspension roller mounting frame and a suspension roller; the limiting pressure roller assembly includes a limiting pressure roller mounting frame and a limiting pressure roller.

[0014] This utility model has the following beneficial technical effects:

[0015] This utility model discloses a belt conveyor conveying device that, by setting a limiting pressure roller assembly, keeps the conveyor belt within the device's running trajectory, effectively controlling the stability of the conveyor belt's operation and greatly reducing the probability of the conveyor belt falling off during operation.

[0016] This invention also incorporates a hanging roller angle adjustment hole. Depending on the different materials being transported by the conveyor belt, the required load-bearing weight varies.

[0025] Example

[0026] A belt conveyor conveying device includes a conveyor belt mounting pipe 1, a conveyor belt 2, a fixing frame, two hanging roller assemblies, and a limiting pressure roller assembly. The fixing frame includes an upper fixing frame 3 and a lower fixing frame 4. The hanging roller assembly includes a hanging roller mounting frame 5 and a hanging roller 6. The limiting pressure roller assembly includes a limiting pressure roller mounting frame 7 and a limiting pressure roller 8. The lower fixing frame 4 includes a middle support 41 and two side supports 42 on the left and right sides. The conveyor belt mounting pipe 1 is fixed to the corresponding civil engineering structure. The upper fixing frame 3 and the lower fixing frame 4 are fixed to the conveyor belt mounting pipe 1 by bolts. The hanging roller 6 is assembled on the hanging roller mounting frame 5 to form a hanging roller assembly. The two assembled hanging roller assemblies are installed on the left and right side supports 42 of the lower fixing frame 4 and are symmetrically distributed. After installation, the two hanging roller assemblies form a certain included angle α, which matches the triangular head of the conveyor belt 2. The included angle α is between 35° and 70°. The limiting pressure roller 8 is assembled on the limiting pressure roller mounting frame 7 to form a limiting pressure roller assembly. The assembled limiting pressure roller assembly is installed on the middle bracket 41 of the lower fixed frame 4, and the conveyor belt 2 passes through the hanging roller assemblies on the left and right sides.

[0027] The left and right side supports 42 of the lower fixed frame 4 are also provided with roller angle adjustment holes 44, which are used to adjust the forward tilt angle β of the roller assembly relative to the running direction of the conveyor belt 2.

[0028] The forward tilt angle β is calculated based on the cantilever beam deflection δ using the following formula:

[0029]

[0030] δ (m): Deflection of the cantilever beam; F (N): External force at the cantilever end; L (m): Length of the cantilever beam; E (Pa): Young's modulus of the material; I (m 4 ): Moment of inertia of the cross section; B (m): Width of the cross section; H (m): Height of the cross section.

[0031] The above parameters are related to the cross-section of the conveyor belt triangular head, the conveying output force, the arrangement and spacing of the hanging roller clamping device, and the material of the triangular head. By calculating δ, the corresponding sag angle β=2δ / L can be approximately calculated. Under the existing model arrangement, the β angle is between 2 and 3°.

[0032] The lower fixed frame 4 has a pressure roller adjustment hole 43 on its intermediate support 41 to adjust the position of the limiting pressure roller assembly and the triangular head of the conveyor belt 2. The hanging roller angle adjustment hole 44 is two or more circular holes, and the pressure roller adjustment hole 43 is an elongated slotted hole.

[0033] The working principle of this invention is as follows: Since the conveyor belt 2 carries different materials, the required load per unit length varies. The forward tilt angle β of the suspension roller assembly relative to the running direction of the conveyor belt 2 is calculated. By adjusting the suspension roller angle adjustment hole 44 on the fixed frame, the suspension roller assembly and the running direction of the conveyor belt 2 are made to form the required forward tilt angle β, generating an upward lifting force. This lifting force provides upward inertia to the conveyor belt 2, counteracting the sagging caused by the weight of the conveyor belt and materials between the two suspension roller assemblies. Simultaneously, by setting the limiting pressure roller assembly at the position of the long groove, the position of the pressure roller assembly and the conveyor belt 2 is adjusted, keeping the conveyor belt always within the running trajectory of the device, effectively controlling the stability of the conveyor belt 2 during operation.

[0034] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
