Description

Technical Field

[0001] The present invention relates to a belt conveyor, and more particularly to the deviation rectification technology of a belt conveyor. Background Art

[0002] Due to reasons such as the installation and manufacture of the belt conveyor, the belt of the belt conveyor will deviate during operation. In minor cases, the belt will be damaged, and in severe cases, it will cause the machine to stop. Stopping the machine in major occasions will cause serious consequences.

[0003] Currently, the common belt deviation rectification mostly adopts deviation rectification mechanisms such as deviation rectification idler groups, fork swing of articulated idler groups, and multi-station notch-fixed idler shafts.

[0004] Among them, the deviation rectification idler group can basically achieve deviation rectification without stopping the machine. The deviation rectification idler group requires a special deviation rectification idler frame, which has a complex structure, a large volume, a heavy weight, unstable quality, a high manufacturing cost, and a low cost performance. Especially, the price of the automatic deviation rectification idler group on the market is expensive.

[0005] The main defect of the fork swing deviation rectification mechanism of the articulated idler group is that the operation is unstable and it is easy to swing back and forth, especially in the running line with inclination angle change, the effect is not good.

[0006] The multi-station notch-fixed idler shaft deviation rectification mechanism has a simple structure, but the defect is that it cannot achieve deviation rectification without stopping the machine because it is too dangerous to change the notch during operation. Summary of the Invention

[0007] Aiming at the problems and defects existing in the existing deviation rectification schemes on belt conveyors, the purpose of the present invention is to provide a new type of deviation rectification mechanism without stopping the machine, which has a simple structure and is convenient to use and operate, so as to overcome the problems existing in the prior art.

[0008] To achieve the above purpose, the present invention provides a deviation rectification mechanism without stopping the machine for a belt conveyor. The deviation rectification mechanism includes a first deviation rectification clamping plate and a second deviation rectification clamping plate. The first deviation rectification clamping plate and the second deviation rectification clamping plate are arranged on the idler side support on the belt conveyor for placing idlers, and are symmetrically distributed on both sides of the clamping groove on the idler side support. The first deviation rectification clamping plate and the second deviation rectification clamping plate can swing respectively towards the clamping groove on the idler side support, and can clamp the idler shaft located in the clamping groove during the swinging process.

[0009] Further, the connection end of the first deviation rectification clamping plate extends outwards to form a first driving and adjusting end, and the first driving and adjusting end has a gradually changing structure relative to the center of the connection end.

[0010] Further, the first driving and adjusting end of the first deviation rectification clamping plate is arc-shaped relative to the center of the connection end.

[0011] Further, a connection end of the second deviation adjusting clamping plate extends outwards to form a second driving and adjusting end, and the second driving and adjusting end has a gradient structure relative to the center of the connection end.

[0012] Further, the second driving and adjusting end of the second deviation adjusting clamping plate is arc-shaped relative to the center of the connection end.

[0013] The belt conveyor non-stop deviation adjusting mechanism provided by the present invention can achieve safe and reliable non-stop deviation adjustment of the belt conveyor, improve the operation efficiency; the deviation adjustment operation is convenient and the deviation adjustment effect is good.

[0014] Furthermore, the belt conveyor non-stop deviation adjusting mechanism provided by the present invention has a simple overall structure, low manufacturing cost and high cost performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0022] In this solution, through the analysis of the deviation phenomenon of the belt conveyor, the mechanism of generating a component force in the opposite direction of the deviation by tilting the idler supporting the belt is adopted to achieve deviation adjustment.

[0023] See Figure 1 , which shows the basic composition structure of the belt conveyor involved in this example. It can be seen from the figure that the belt conveyor 100 is mainly composed of an H-shaped leg 110, an intermediate frame 120, a lower idler 130 and an upper idler 140 in cooperation.

[0024] Among them, the intermediate frame 120 is fixedly connected to the H-shaped leg 110. The upper idler 140 is arranged on the intermediate frame 120, and the lower idler 130 is arranged on the H-shaped leg 110 through the corresponding idler side support 150.

[0025] Here, the specific structures of the H-shaped leg 110, the intermediate frame 120, the lower idler 130, and the upper idler 140 are not limited and can be determined according to actual needs.

[0026] As Figure 2 shown, for the lower idler 130 in this embodiment, the lower idler shaft 131 thereon is fixed in the card slot 151 of the idler side support 150, thereby realizing the placement of the lower idler 130.

[0027] Refer to Figure 3 , for this structure, in this embodiment, a corresponding deviation adjustment mechanism 200 is arranged on the idler side support 150. The deviation adjustment mechanism 200 directly locks and adjusts the lower idler shaft 131 in the card slot 151 of the idler side support 150 by means of cam locking, and then realizes deviation adjustment.

[0028] Here, the deviation adjustment mechanism 200 is specifically composed of a first deviation adjustment card plate 210 and a second deviation adjustment card plate 220 in cooperation.

[0029] Among them, the first deviation adjustment card plate 210 and the second deviation adjustment card plate 220 are rotatably arranged on the idler side support 150 for placing the idler on the belt conveyor and are symmetrically distributed on both sides of the card slot 151 on the idler side support; at the same time, the first deviation adjustment card plate 210 and the second deviation adjustment card plate 220 can swing towards the card slot 115 on the idler side support respectively and can clamp or loosen the idler shaft 131 located in the card slot 151 during the swinging process.

[0030] As an example, the first deviation adjustment card plate 210 and the second deviation adjustment card plate 220 here are preferably of the same structure, but according to the design, it is not limited to this.

[0031] Here, taking the first deviation adjustment card plate 210 as an example, its composition structure will be described.

[0032] As Figure 4 shown, the first deviation adjustment card plate 210 has an overall plate-like structure, including a connection end 211. The connection end 211 is overall circular, and at the same time, a corresponding connection hole 212 is opened on the connection end 211 to cooperate with the corresponding pin shaft 230 to realize the fixation of the deviation adjustment card plate to the idler side support 150.

[0033] Based on the circular connection end 211, a connection section 213 extends outward. The structural form of the connection section 213 is not limited here. In the illustrated case, it is a square structure.

[0034] Meanwhile, a first driving and adjusting end 214 is formed at the free end of the connecting section 213, and the first driving and adjusting end 214 has a gradually changing structure with respect to the rotation center of the connecting end. That is, the distance between the end face of the first driving and adjusting end 214 and the rotation center of the connecting end is gradually changing along the extending direction of the end face.

[0035] When the thus formed first deviation adjusting plate 210 is swingably arranged on one side of the clamping groove 151 of the idler side support, when rotating towards the clamping groove 151, it will form a gradually changing pressing or loosening structure on the surface of the lower idler shaft 131 in the clamping groove 151, realizing the locking or loosening of the lower idler shaft 131.

[0036] On this basis, the first driving and adjusting end 214 of the first deviation adjusting plate 210 is arc-shaped with respect to the rotation center of the connecting end, preferably circular arc-shaped. In this way, it can well cooperate with the outer surface of the lower idler shaft 131 to ensure the reliability of the clamping adjustment.

[0037] The second deviation adjusting plate 220 in this embodiment adopts the same structure as the first deviation adjusting plate 210, and will not be elaborated here.

[0038] The first deviation adjusting plate 210 and the second deviation adjusting plate 220 in this embodiment are installed and arranged. They are rotatably arranged on the idler side support 150 through the pin shaft 230 by the connecting holes 212 thereon, and are distributed on both sides of the clamping groove 151 thereon. When the first deviation adjusting plate 210 and the second deviation adjusting plate 220 swing towards the clamping groove 151 around their respective pin shafts 230, the driving and adjusting ends thereon can both form driving clamping on the idler shaft 131 located in the clamping groove 151.

[0039] See Figure 5 , which shows an example of the composition of the pin shaft 230 used in this embodiment. The pin shaft 230 preferably adopts a multi-stage circular step structure, which is convenient for fixed setting.

[0040] The deviation adjusting mechanism 200 given in this embodiment is cooperatively arranged with the belt conveyor. The first deviation adjusting plate 210 and the second deviation adjusting plate 220 are respectively arranged on the idler side support 150 through the pin shaft 230, and are symmetrically distributed on both sides of the clamping groove 151 thereon. Among them, the height of the center of the pin shaft 230 on the first deviation adjusting plate 210 and the second deviation adjusting plate 220 is higher than the height of the idler shaft center in the clamping groove 151. This is preferably 2 - 4 millimeters higher, not on the same straight line, and offset by a certain distance up and down, thereby forming a cam eccentricity, so that the working states of the two deviation adjusting plates can clamp the idler shaft and are safe and reliable.

[0041] Thus, for the belt supporting rollers installed on the H-shaped legs 110 of the belt conveyor, based on the running direction of the belt, such as moving from the first direction to the second direction. At this time, the first deviation adjusting plate 210 can swing towards the card slot 151, and then clamp the roller shaft in the card slot 151. Based on the mechanism of the eccentricity of the deviation adjusting plate cam, the tighter the roller is clamped when the roller is stressed in the second direction, and the roller does not tilt forward at this time; when the first deviation adjusting plate 210 is lifted, the roller shaft in the card slot 151 will move forward. At this time, the second deviation adjusting plate 220 is lowered (i.e., swings towards the card slot 151) to clamp the roller shaft. At this time, the roller is in a forward tilt condition, realizing belt deviation adjustment, and the whole operation process does not require shutdown.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
