Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of material conveying equipment, and particularly relates to a tubular belt conveyor deviation rectifying roller support. BACKGROUND

[0002] The tubular belt conveyor is a kind of high-efficiency and environmentally-friendly material conveying equipment, which is widely used in mining, power, chemical industry, building materials and other industries. Its core feature is that the conveying belt is curled into a tubular shape during operation, completely wrapping the material inside, thereby realizing closed conveying. This design effectively prevents material from spilling, dusting and pollution during conveying, and is particularly suitable for conveying powdery, granular or easily-dusting materials such as coal, cement and ore. The tubular belt conveyor is composed of a driving device, a roller set, a conveying belt, a tensioning device and a support, etc. The conveying belt is supported and guided by the roller set to form a tubular structure, and returns to a flat belt state at the discharge end. This equipment has the advantages of long conveying distance, small turning radius, adaptability to complex terrain, etc., and can realize horizontal, inclined and curved conveying. In addition, the tubular belt conveyor runs smoothly, with low noise and low energy consumption, and has low maintenance cost, so it is a kind of high-efficiency and energy-saving material conveying solution. Through an intelligent control system, remote monitoring and automatic operation can also be realized, further improving production efficiency and safety.

[0003] As a kind of high-efficiency and environmentally-friendly material conveying equipment, the tubular belt conveyor has significant advantages in scenes with strict environmental requirements due to its closed tubular structure. During operation, the tubular belt conveyor is prone to lateral deviation of the conveying belt due to uneven distribution of materials, installation deviation of the drum, dynamic tension fluctuation and other factors. The traditional deviation rectification method relies on manual shutdown adjustment, which is low in efficiency and insufficient in accuracy.

[0004] Therefore, there is a need for a tubular belt conveyor deviation rectifying roller support to solve the problems raised in the above background. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a kind of tubular belt conveyor deviation rectifying roller support to solve the problems raised in the above background.

[0008] It is worth mentioning in the scheme that the first connecting shaft and the second connecting shaft are connected between the two adjacent roller bases.

[0009] It is further worth mentioning that the roller bases are provided with the shaft clamping plates for clamping and limiting the first, second and third fixed rotating shafts.

[0014] 1. The utility model provides a kind of pipe belt conveyor deviation correction roller support, compared with traditional manual correction mode, deviation correction roller support can more accurately adjust the position and angle of roller, make the contact between roller and conveying belt more reasonable.When conveying belt deviates, the support can respond in time and change the posture of roller, produce suitable deviation correction force, guide conveying belt back to correct running position, effectively reduce the phenomenon of conveying belt deviation, ensure the stable operation of pipe belt conveyor.Greatly high deviation correction efficiency and avoid the technical problem of inaccurate manual correction.

[0015] 2. The utility model provides a kind of pipe belt conveyor deviation correction roller support, the support has good flexibility and adaptability, can effectively correct different degrees, different direction conveying belt deviation problem.For slight deviation or more serious deviation, deviation can be corrected by adjusting the angle and position of roller, improve the running stability of conveyor under various working conditions.

[0016] 3. The utility model provides a kind of pipe belt conveyor deviation correction roller support, can reduce the abnormal wear between roller and conveying belt by timely and effective deviation correction.When conveying belt deviates, excessive friction will be generated with the edge of roller, which leads to the shortening of service life of roller and conveying belt.Deviation correction roller support can avoid this situation, reduce the replacement frequency of roller and conveying belt, reduce the downtime maintenance time of equipment, thereby saving equipment maintenance cost.

Specific implementation

[0022] The utility model is further described below in combination with examples.

[0023] Please refer to Figures 1-3 The utility model provides a tubular belt conveyor deviation rectification carrier roller support, including hexagonal truss 15, the inside fixed multiple carrier roller base 3 of hexagonal truss 15, all rotatable connections have carrier roller 14 on multiple carrier roller base 3, install first fixed pivot 4, second fixed pivot 8 and third fixed pivot 10 on the side surface of carrier roller base 3, rotatable connection has first roller 2, second roller 5, third roller 9 and fourth roller 12 on carrier roller base 3, wherein one carrier roller base 3 is fixed with electric push rod 1, and first connecting shaft 6 and second connecting shaft 13 are connected between adjacent two carrier roller base 3, and multiple carrier roller base 3 all install clamping shaft plate 11, and first fixed pivot 4, second fixed pivot 8 and third fixed pivot 10 are fixed and positioned through clamping shaft plate 11, and spherical surface connecting block 7 that cooperates with first connecting shaft 6 and second connecting shaft 13 is installed on carrier roller base 3;When tubular conveying belt twists left or right in tubular section, conveying belt receives asymmetric torque along the axial (running direction), causes tubular section to produce left or right spin deformation, at this moment, three diagonal hexagonal carrier roller groups under tubular belt conveyor will change due to the support force direction of carrier roller 14 to conveying belt, and one side carrier roller 14 can bear greater radial pressure, and the other side carrier roller 14 reduces pressure due to the separation of conveying belt, at this moment, deviation rectification carrier roller support can be operated according to the twisting direction of conveying belt.

[0024] Further as Figure 1 It is worth specifically explaining that the side surface of carrier roller base 3 is fixed with fixed base, and electric push rod 1 is fixedly installed on the fixed base.

[0025] Further asFigure 1 and Figure 2 As shown, it is worth noting that the multiple idlers 14 are symmetrically distributed, and the spacing between two adjacent idlers 14 is equal.

[0026] This solution has the following working process: There are three main control states: When the conveyor belt deviates to the right, the electric push rod 1 retracts, driving the right idler base 3 to move in the opposite direction, and coordinating the adjustment of the angles of the middle and left idlers 14. The specific implementation steps are as follows: Controlling the retraction of the electric push rod 1 causes the upper part of the right idler base 3 to move in the opposite direction to the conveyor belt. At the same time, through the cooperation of the lower connecting shaft 6 and the right spherical connecting block 7, the right side of the middle idler base 3 moves in the opposite direction to the conveyor belt. The left spherical connecting block 7 is affected by the displacement of the middle idler base 3 and guided by the connecting shaft 13, the lower part of the left idler base 3 moves in the opposite direction to the conveyor belt. At this time, the angle between the lower three sets of idlers of the hexagonal idler group and the running direction of the conveyor belt is consistent, and finally the correction effect is achieved; When the conveyor belt deviates to the left, the electric push rod 1 extends, driving the right idler 14 to move in the forward direction, and coordinating the adjustment of the angles of the middle and left idlers 14 in the opposite direction. The specific implementation steps are as follows: control the extension of the electric push rod 1, the upper part of the right idler base 3 moves in the direction of the conveyor belt, and at the same time, through the cooperation of the lower connecting shaft 6 and the right spherical connecting block 7, the left side of the middle idler base 3 moves in the direction of the conveyor belt. The left spherical connecting block 7 is affected by the displacement of the middle idler base 3, and guided by the connecting shaft 13, the upper part of the left idler base 3 moves in the direction of the conveyor belt. At this time, the angle between the lower three sets of idlers of the hexagonal idler group and the direction of the conveyor belt is consistent, and finally the correction effect is achieved. When the conveyor belt is in normal condition, the electric push rod 1 remains in the original position, the idler group mechanism does not move, and the angle of the idler group coincides with the angle of the conveyor belt.

[0027] The electric linear actuator 1 can be purchased from the market. The electric linear actuator 1 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
