Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of belt conveyors, especially to a V-shaped adjustable front-inclined supporting roller and supporting leg integrated arrangement structure. BACKGROUND

[0002] In the field of material conveying, the belt conveyor is widely used due to its high efficiency and reliability. However, the V-shaped front-inclined supporting roller group and supporting leg column of the traditional belt conveyor are arranged in a split mode, which has the following inherent defects:

[0003] (1) Fixed front-inclined angle: The front-inclined angle of the traditional supporting roller group is fixedly designed (such as 1° or 2°), which cannot dynamically adjust the front-inclined angle of the roller according to the lateral deviation of the conveying belt, leading to easy deviation of the conveying belt when turning or load changes, aggravating edge wear, and even causing belt tearing accidents.

[0004] (2) Theoretical belt surface height is not adjustable: The V-shaped front-inclined supporting roller group and supporting leg column of the traditional belt conveyor are arranged in a split mode, the cross beam on which the supporting roller group is installed is hung below the middle frame through the hangers at both ends, and the theoretical belt surface height is determined by the height of the preset hangers. When the theoretical belt surface height needs to be changed, the hangers need to be cut to reduce their height or the hangers need to be raised to adjust the height of the supporting roller group relative to the middle frame, which greatly increases the installation cost and prolongs the construction period.

[0005] (3) The height of the supporting leg is not adjustable: The height of the supporting leg column is fixed, which cannot adapt to the height deviation (±50mm) of the bottom foundation, and needs to be adjusted by manually stacking shims or cutting the supporting leg column, which is complicated to operate and easy to cause the supporting leg to tilt, affecting the structural stability.

[0006] (4) Material redundancy and high cost: The traditional supporting leg is designed with angle steel diagonal braces and angle steel cross beams, and the V-shaped supporting roller group also needs angle steel cross beams to meet the bending strength requirement. Due to the low sectional efficiency of angle steel, the size needs to be increased, leading to an increase of 25%-30% in the amount of steel, a heavy structure, and a significant increase in transportation and installation costs.

[0007] The above problems are particularly prominent in complex scenarios such as factory system layout and off-road terrain, which seriously restricts the economy and reliability of the conveying system. INVENTION CONTENTS

[0008] In order to overcome the problems in the above background art, the utility model provides a V-shaped adjustable front-inclined supporting roller and supporting leg integrated arrangement structure, which has the beneficial effects of infinitely adjustable front-inclined angle, dynamic correction of conveying belt deviation, adjustable theoretical belt surface height, adjustable supporting leg height, cost saving, improved bending strength, and improved running stability.

[0017] Preferably, the bottom of the supporting leg column is fixed on a horizontally arranged supporting leg bottom plate, the supporting leg bottom plate is provided with embedded bolts vertically penetrating the plate surface, and the lower part of the embedded bolts is fixed in the bottom foundation; the embedded bolts below the supporting leg bottom plate are provided with nuts, and the height of the supporting leg column can be adjusted by changing the connecting position of the nut and the embedded bolt; the embedded bolts below the supporting leg bottom plate are fixedly connected with the bottom foundation through grouting; and the height adjustment range of the supporting leg column is 0±50 mm.

[0018] Preferably, the top of each two-sectioned leg column is provided with an intermediate frame extending along the running direction of the conveying belt, and the two sides of each sectioned leg column are fixedly connected with the intermediate frame through inclined struts.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Example 1: As Figures 1 to 4 The V-shaped adjustable forward tilting idler and the support leg integrated arrangement structure shown includes two opposing support leg columns 1, the support leg columns 1 are vertically fixed on the bottom foundation 13, and a horizontally arranged crossbeam 2 is fixed between the two support leg columns 1.

[0034] The idler roller assembly 3 is arranged on the same side of the crossbeam 2. The two outer end shafts of the idler roller assembly 3 can be moved back and forth along the running direction of the conveyor belt 4 to adjust the installation position, thereby adjusting the forward tilt angle of the idler roller assembly 3. Since the outer end shafts of the idler roller assembly 3 can be moved back and forth along the running direction of the conveyor belt 4 to adjust the installation position, the forward tilt angle of the idler roller assembly 3 can be dynamically adjusted according to the lateral deviation of the conveyor belt 4. That is, the forward tilt angle β2 of the idler roller assembly 3 can be dynamically adjusted. The forward tilt angle is the angle between the axis of the idler roller assembly 3 and the plane perpendicular to the running direction of the conveyor belt 4 when it is installed, that is, the angle of forward tilt. By dynamically adjusting the forward tilt angle of the idler roller assembly 3, the problem of the conveyor belt 4 easily running off-center when turning or changing load can be avoided, which can aggravate edge wear and even cause belt tearing accidents.

[0035] Example 2: On the basis of example 1, the front inclination angle adjustment of the roller set 3 is optimized as shown in Figure 3 As shown, the two ends of the front side or the rear side of the crossbeam 2 are respectively fixed with side support columns 5 extending along the vertical direction of the side of the crossbeam 2, wherein one side of the side support column 5 is fixed with an adjustable lug 6 in parallel through detachable connection, and the two outer end shafts of the roller set 3 pass through the side support column 5 and the adjustable lug 6. Specifically, in this embodiment, the adjustable lug 6 is located on the outer side of the side support column 5, i.e. on the side of the side support column 5 away from the roller set 3, and the side support column 5 is provided with a first long hole 51 having the same length direction as the running direction of the conveying belt 4, and the adjustable lug 6 is provided with a flat square hole 61, and the two outer end shafts of the roller set 3 pass through the first long hole 51 and the flat square hole 61 in sequence. The two sides of the first long hole 51 are provided with screw holes 52 arranged on the side support column 5, and the two sides of the flat square hole 61 are provided with second long holes 62 arranged on the adjustable lug 6, which also have the same length direction as the running direction of the conveying belt 4, and the side support column 5 and the adjustable lug 6 are fixedly connected by fasteners passing through the screw holes 52 and the second long holes 62. The front inclination angle of the roller set 3 ranges from 0° to 2° as shown in Figure 4 Figure 4 The middle front inclination angle β2 equal to 2° is the maximum front inclination angle, so the forward inclination angle of the roller set 3 is very small and will not affect the normal installation of the outer end shafts of the roller set 3. The long holes arranged on the side support column 5 and the adjustable lug 6 are beneficial to the connection stability of the side support column 5 and the adjustable lug 6.

[0036] When installing the roller set 3, first adjust the position of the adjustable lug 6 on the side support column 5 along the running direction of the conveying belt 4 according to the actual situation, and make the hole positions of the adjustable lug 6 correspond to the hole positions of the side support column 5 one by one, and then use fasteners to pass through the screw holes 52 and the second long holes 62 at the same time to fixedly connect the side support column 5 and the adjustable lug 6, wherein the fasteners can be selected as bolts and nuts matched in connection, and finally pass the two outer end shafts of the roller set 3 through the corresponding first long holes 51 and flat square holes 61 in sequence. When adjusting the roller set 3, only need to loosen the fasteners, then slide the adjustable lug 6 along the running direction of the conveying belt 4, and after adjusting to the target front inclination angle, tighten the fasteners.

[0037] Therefore, by setting different connection positions of the flat square hole 61 of the adjustable lug 6 and the first long hole 51 of the side support column 5, and passing the outer end shafts of the roller set 3 through the connection positions of the first long hole 51 and the flat square hole 61, the stepless adjustment of the front inclination angle of the roller set is realized, the front inclination angle of the roller set 3 can be dynamically adjusted according to the deviation amount, the deviation of the conveying belt 4 is effectively corrected, and the risk of edge wear and tearing of the conveying belt 4 is greatly reduced.

[0038] Preferably, as shown in Figure 1 ​As shown, the crossbeam 2 is a steel pipe bent into a V-shaped structure, the roller set 3 includes two rollers 31 arranged on the same side of the crossbeam 2 and along the crossbeam 2 to form a V-shaped roller set 3; the groove angle β1 of the roller set 3 is 10° or 15°, and the radius R ranges from 300 mm to 600 mm, and the specific radius R and groove angle β1 are set according to the belt width and groove angle of the roller set 3. The V-shaped roller set 3 combined with the front inclination angle stepless adjustment of the roller set 3 reduces the deviation rate of the conveying belt 4, reduces wear and tear, and has wide applicability.

[0039] Further preferably, the middle part of the crossbeam 2 is fixed with two middle supporting ears 21, the top middle part of the middle supporting ear 21 is recessed to form a clamping groove 211, and the outer end shaft of the two rollers 31 passes through the side supporting column 5 and the adjustable supporting ear 6, and the inner end shaft is clamped into the clamping groove 211 at the top of the middle supporting ear 21. When installing the roller 31, after fixing the side supporting column 5 and the adjustable supporting ear 6, the outer end shaft of the roller 31 is first passed through the side supporting column 5 and the adjustable supporting ear 6, and then the inner end shaft is placed into the clamping groove 211 of the middle supporting ear 21. This structure can not only lock the roller 31 and stably install the roller set 3, but also realize the front inclination angle stepless adjustment of the roller set 3, adapt to different working conditions, and improve the installation efficiency.

[0040] In example 3, the crossbeam 2 is preferably designed based on example 1, the two ends of the crossbeam 2 are respectively fixed with end plates 22, the upper part and the lower part of the end plate 22 are respectively provided with mounting holes 221, the mounting holes 221 are vertically arranged long hole structures, the supporting leg column 1 is provided with a through hole, the through hole can be connected with different positions of the mounting hole 221, when installing the crossbeam 2, after determining the theoretical belt surface height according to the actual situation, the fixing height of the crossbeam 2 is determined according to the theoretical belt surface height, the connection position of the mounting hole 221 of the end plate 22 and the through hole of the supporting leg column 1 is adjusted, then a bolt is used to pass through the mounting hole 221 and the through hole, and a nut is used to fix the connection. When it is necessary to adjust the theoretical belt surface height, only the fastener needs to be loosened, then the installation position of the end plate 22 on the supporting leg column 1 is changed until the target theoretical belt surface height is reached, and then the fastener is tightened.

[0041] The mounting hole 221 of the vertically arranged long hole structure of the end plate 22 at both ends of the cross beam 2 is matched with the through hole on the leg column 1, so that the theoretical belt surface height can be quickly changed by adjusting the mounting position of the cross beam 2 on the leg column 1, that is, the theoretical belt surface height can be adapted by changing the mounting position of the cross beam 2 on the leg column 1. This structure does not need to disassemble the cross beam 2 or cut the leg, and only needs to loosen the bolt and move the cross beam 2 up and down to complete the height adaptation, significantly reducing the risk of structural stability caused by repeated disassembly and assembly, adapting to the layout adjustment of the factory area or the terrain undulation demand, reducing the installation cost, and not affecting the construction period. The adjustment range of the theoretical belt surface height is 0±20mm, that is, the height position of the through hole of the leg column 1 can be adjusted up and down by 20mm, which can adapt to the adjustment of the theoretical belt surface height in different working conditions, and the installation efficiency is improved.

The height of the leg column 1 can be adjusted by changing the connection position of the nut and the embedded bolt 14, and the embedded bolt 14 below the leg bottom plate 12 is fixed and connected with the bottom foundation 13 through grouting.

[0043] When the leg column 1 is installed, the up and down nut positions of the embedded bolt 14 are adjusted according to the foundation deviation (such as 20mm), the verticality of the leg column 1 is ensured to meet the standard, then the leg bottom plate 12 is fastened through the up and down nuts, and the bottom foundation 13 below the leg bottom plate 12 is grouted again to improve the stability of the structure, so that when the foundation height deviation of the leg column 1 is met, the height can be adjusted by the reserved height of the embedded bolt 14 and the up and down nuts. The height adjustment range of the leg column 1 is 0±50mm, that is, the height of the leg column 1 itself can be adjusted up and down by 50mm.

[0044] The leg bottom plate 12 and the embedded bolt 14 are fixedly connected through the nut, and the height of the leg column 1 is adjusted by screwing the nut, which can accurately compensate for the ±50mm height deviation in foundation construction.
