Description

Technical Field

[0001] This utility model belongs to the field of mechanical device technology, and in particular relates to an integrated deflection structure for a mining belt conveyor. Background Technology

[0002] In practical applications of mining belt conveyors, deflection devices are frequently used. However, existing deflection devices are typically split-type vertical rollers or baffles. This split structure suffers from cumbersome installation, poor positioning accuracy, and the need for individual installation, alignment, and fixing of traditional deflection rollers. This process is time-consuming and labor-intensive, and it's difficult to ensure that the axes of multiple deflection rollers are perfectly perpendicular to the conveyor frame and at the same height. Installation errors can easily lead to poor deflection correction and even accelerated wear. Furthermore, maintenance costs are high. Due to these issues, traditional devices require frequent inspections, tightening, and component replacements by maintenance personnel, increasing downtime and labor and material maintenance costs. Therefore, developing a deflection structure that is easy to install, durable, and provides good deflection correction is a challenging problem that has been a constant concern for those skilled in the art. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated deflection structure for mining belt conveyors, which solves the technical problems of complex installation process, low efficiency and high operation and maintenance cost of the existing deflection structures.

[0004] The technical solution adopted by this utility model to solve its technical problem is: An integrated deflection structure for a mining belt conveyor includes: several pairs of support columns, with a bottom belt support roller between the lower parts of each pair of support columns to support the lower belt; a longitudinal beam at the top of each adjacent support column; several top belt support rollers spaced apart along the length of the longitudinal beams to support the upper belt; and several integrated deflection devices installed in pairs along the length of both sides of the lower belt. The bottom of each integrated deflection device is connected to the support column, and the upper part of each integrated deflection device is connected to the longitudinal beam. The integrated deflection devices deflect the lower and upper belts respectively.

[0005] This utility model discloses an integrated deflection structure for a mining belt conveyor. The integrated deflection device includes a deflection plate, on the surface of which two sets of deflection rollers are installed, corresponding to the lower belt and the upper belt, respectively.

[0006] This utility model discloses an integrated deflection structure for a mining belt conveyor. The two ends of the deflection roller are connected to the deflection plate through a first deflection support and a second deflection support, respectively. The second deflection support and the deflection plate are connected by welding, and the first deflection support and the deflection plate are connected by welding and double-connected with the support mounting bolts.

[0007] This utility model discloses an integrated deflection protection structure for a mining belt conveyor, wherein the bottom of the deflection protection plate has a baffle plate that extends horizontally.

[0008] This utility model discloses an integrated deflection blocking structure for a mining belt conveyor. The upper part of the deflection blocking plate is quickly installed to the longitudinal beam via a central quick-connect structure, and the lower part of the deflection blocking plate is quickly installed to the supporting column via a lower quick-connect structure.

[0009] This utility model discloses an integrated deflection control structure for a mining belt conveyor. The central quick-connect structure is a clamp, and the deflection control plate has bolt holes corresponding to the clamp. The clamp is fastened to the longitudinal beam and connected to the deflection control plate by bolts.

[0014] The beneficial effects of this utility model are as follows: It proposes an integrated deflection structure for mining belt conveyors, making the deflection device an integrated structure. This allows the installation parameters of each component to be pre-set and tested during assembly, thereby improving the efficiency and accuracy of on-site assembly, greatly simplifying the installation process, eliminating cumulative installation errors, and ensuring the optimal correction angle. Furthermore, the quick-connect structure further improves installation and maintenance efficiency; when a local area is damaged, only the integrated deflection structure needs to be replaced. The rubber wear-resistant layer structure increases friction and protects the belt surface. The bent deflection plate ensures that the distance between the deflection roller and the upper and lower belts is similar or the same, thereby improving the deflection effect and preventing uneven force distribution on the upper and lower belts.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figure 1-4 As shown, an integrated deflection structure for a mining belt conveyor includes: several pairs of support columns 100; a bottom belt support roller 400 is provided between the lower parts of each pair of support columns 100 to support a lower belt 600; a longitudinal beam 200 is provided at the top of each adjacent support column 100; several top belt support rollers 500 are spaced apart along the length of the longitudinal beams 200 to support an upper belt 700; several integrated deflection devices 300 are installed in pairs along the length of both sides of the lower belt 600; the bottom of each integrated deflection device 300 is connected to the support column 100; the upper part of each integrated deflection device 300 is connected to the longitudinal beam 200; and the integrated deflection devices 300 deflect the lower belt 600 and the upper belt 700 respectively.

[0018] It should be noted that the integrated anti-deviation device 300 is placed on the support of the belt conveyor, typically in sections where the belt is prone to deviation, such as the head, tail, and convex arc sections. It is supported by the longitudinal beam 200. The appropriate distance between the integrated anti-deviation device 300 and the edge of the belt is adjusted, typically 50-70mm from both sides of the belt width. Then, the baffle 370 of the device is connected to the support column 100 using U-shaped clamps and bolts, simultaneously blocking the upper belt 700 and the lower belt 600. When the belt deviates to one side, its edge contacts the anti-deviation roller 320. Under the action of friction, the roller rotates and guides the belt back to the center position, thus achieving the automatic deviation correction function. By integrating the two anti-deviation rollers 320 with a sturdy steel plate, i.e., the anti-deviation plate 310, into a rigid whole, the parallelism, perpendicularity, and relative positional accuracy of the two rollers are guaranteed at the factory. During on-site installation, the entire device can be fixed to the conveyor frame in one go, greatly simplifying the installation process, eliminating accumulated installation errors, ensuring the optimal correction angle, and enhancing the overall structural strength and stability. The use of an integral steel plate structure as the base provides far superior rigidity compared to separate, individual supports. It effectively resists the severe impact of the conveyor belt, preventing deformation or displacement of the device itself due to impact, and ensuring long-term stable and reliable operation.

[0019] In a preferred embodiment, the integrated deflection device 300 includes a deflection plate 310, on the surface of which two sets of deflection rollers 320 are mounted, the two sets of deflection rollers 320 corresponding to the lower belt 600 and the upper belt 700 respectively.

[0020] In a preferred embodiment, the two ends of the deflector roller 320 are connected to the deflector plate 310 via a first deflector support 330 and a second deflector support 360, respectively. The second deflector support 360 is welded to the deflector plate 310, and the first deflector support 330 is welded to the deflector plate 310 and doubly connected to the support mounting bolts 340. The deflector supports are securely welded to the upper surface of the deflector plate using a continuous full-welding method. The weld leg dimensions are calculated to ensure that their shear and torsional strengths are far greater than the maximum expected impact force of the belt.

[0021] It should be noted that both the first deflection support 330 and the second deflection support 360 can be L-shaped structures, that is, one side is in contact with the deflection plate 310, and the second deflection support 360 can also be a composite connection of welding and bolting.

[0022] In a preferred embodiment, the bottom of the deflector plate 310 has a baffle plate 370, which extends in a horizontal direction.

[0023] In a preferred embodiment, the upper part of the deflector plate 310 is quickly installed to the longitudinal beam 200 via the middle quick-connect structure 350, and the baffle plate 370 is quickly installed to the support column 100 via the lower quick-connect structure 380.

[0024] In a preferred embodiment, the central quick-connect structure 350 is a clamp, and the deflection plate 310 has bolt holes corresponding to the position of the clamp. The clamp is fastened to the longitudinal beam 200 and connected to the deflection plate 310 by bolts.

[0025] In a preferred embodiment, the lower quick-connect structure 380 is a U-shaped clamp, and the baffle 370 has a connection hole at the position corresponding to the U-shaped clamp. The U-shaped clamp is attached to the support column 100 and passes through the baffle 370 before being locked by a nut.

[0026] In a preferred embodiment, the middle part of the deflection plate 310 has a bent structure, which makes the distance between the deflection roller 320 and the upper belt 700 closer, thus optimizing the correction effect. The two deflection rollers are fixed in a rigid optimal position, which can simultaneously form two stable and effective constraint points for the belt deviation section, thereby providing a stronger and more reliable correction force, effectively preventing belt deviation, and protecting the belt edge from damage.

[0027] In a preferred embodiment, the baffle 370 and the deflector plate 310 are fixedly installed using a common support mounting bolt 340 at their connection.

[0028] In a preferred embodiment, the surface of the deflector roller 320 has a rubber wear-resistant layer structure, and both ends of the shaft of the deflector roller 320 are supported in the support by double-sealed deep groove ball bearings, ensuring that it can still rotate flexibly in a dusty environment and guide the belt with low resistance.
