Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of belt conveyor, especially to a big bandwidth adjustable front-inclined V-shaped carrier roller group quick dismounting device with handle. BACKGROUND

[0002] In the field of material conveying, the belt conveyor as the core conveying equipment has become the key equipment for bulk material transportation with the advantages of strong continuous conveying capacity and high running efficiency. Among them, the V-shaped front-inclined carrier roller group as an important guiding component of the belt conveyor can play a certain deviation correction effect on the deviation of the conveying belt through the design of the front-inclined angle. However, the traditional V-shaped front-inclined carrier roller group has significant technical defects in actual application, which are specifically as follows:

[0003] (1) Low dismounting efficiency: the traditional V-shaped front-inclined carrier roller crossbeam is an integral welded structure of a hanging bracket and a horizontal rod, the carrier roller group crossbeam is fixed on the middle frame as a whole, and the roller is connected with the carrier roller group crossbeam through a clamping groove. When replacing the roller, the carrier roller group crossbeam needs to be dismounted as a whole, which requires a large amount of dismounting work, or the conveying belt on the carrier roller group is manually pried up, and then the roller is replaced. The conveying belt is heavy in quality, large in size and tension, and it is very laborious to pry up the conveying belt manually. Both of the above-mentioned methods require a large amount of time (up to 2-3 hours) and the cooperation of multiple people, which is labor-intensive.

[0004] (2) Large safety hazard: in the tunnel or high-altitude working environment with limited space, the above-mentioned two traditional dismounting methods require the operator to carry tools and work for a long time, which is difficult to operate and increases the risk of tools and rollers falling off. When the conveying belt is manually pried up, the improper force may cause damage to the conveying belt or the operator to slip, further increasing the probability of safety accidents.

[0005] (3) Fixed front-inclined angle: the existing carrier roller group adopts a fixed front-inclined angle design, which cannot adjust the angle according to the real-time deviation state of the conveying belt, resulting in a significant increase in the sliding friction between the conveying belt and the carrier roller. Long-term operation will accelerate the wear of the edge of the conveying belt, and even cause local rupture.

[0006] The existing improvement scheme (such as the pre-reserved front-inclined clamping groove adjustment type carrier roller group) partially alleviates the problem, but still has problems such as fixed adjustment angle and complicated roller dismounting steps. INVENTION CONTENTS

[0018] Its advantages are as follows: the connecting plate is located at the center of the inner side of the single guide rail, which facilitates the connection between the positioning pin and the idler bracket. The positioning pin is arranged on both sides of the connecting plate and perpendicular to it, making it easy to connect two sets of idler brackets simultaneously. The reinforcing ribs can improve the strength and load-bearing capacity of the guide rail support. The galvanized surface of the single guide rail and the epoxy anti-corrosion coating on the surface of the idler bracket can prevent rust from occurring, which would prevent the idler bracket from sliding normally on the guide rail support, making it suitable for use in high-humidity environments in ports. The contact surface between the single guide rail and the carriage is provided with a graphite lubricating layer, which can reduce the operating force for pulling the idler bracket to 40N, making it easier to move the idler bracket in or out.

[0019] More preferably, the single guide rail is made of channel steel with the groove facing outward; the carriage is made of angle steel that matches the structure of the single guide rail; and the surfaces of the two carriage sections in each set of roller brackets are also fixed with reinforcing plates that connect the two.

[0020] Its beneficial effects are as follows: by setting up a single guide rail with a channel steel structure and a carriage made of angle steel that matches the single guide rail structure, the angle steel is upside down on the single guide rail. In conjunction with the use of the reinforcing plate, the connection stability of each set of idler roller brackets in the width direction is increased, and the carriage is prevented from being misaligned in the width direction of the single guide rail, which would be detrimental to the overall stability. The reinforcing plate is used to connect the two sections of the carriage of each set of idler roller brackets, so that the two sections of the carriage form a whole.

[0021] More preferably, the roller bracket has a side support and a middle support at both ends for mounting the roller assembly.

[0022] Its beneficial effects are as follows: the side support and the middle support are used to install the rollers of the idler assembly and can connect the inner sides of the two carriages, further improving the connection stability of the carriage; the two ends of the idler bracket are respectively connected to the guide rail support by positioning pins and detachable fasteners, so that when the roller needs to be replaced, only the fasteners on the side of the idler assembly mounting frame need to be manually removed, and the idler bracket can be pulled out. The positioning pin can then be disengaged from the middle support, which is very convenient. After the replacement is completed, the idler bracket can be firmly connected to the guide rail support.

[0023] More preferably, the top of the side support column is provided with an adjustment groove, the length direction of which is consistent with the length direction of the conveyor belt, and one side of the adjustment groove is provided with an adjustment plate fixed parallel to the side support column; the outer end shaft of the idler roller group passes through the adjustment groove and the adjustment plate and can move back and forth in the adjustment groove to adjust the forward tilt angle of the idler roller group; the forward tilt angle has a stepless adjustment range of 0°-2°.

[0024] Its beneficial effects are as follows: this structure can lock the rollers and stably install the idler roller group, and can also realize stepless adjustment of the forward tilt angle of the idler roller group to adapt to different working conditions, improve the correction capability, extend the service life of the conveyor belt, and make it very simple and quick to replace the rollers, thus improving the replacement efficiency.

[0025] In a further preferred embodiment, each set of idler roller supports is provided with a handle column between the side support and the middle support.

[0037] 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.

[0038] Example 1: As Figures 1 to 8 The illustrated quick-release device for a wide-band adjustable forward-tilting V-shaped idler assembly with handle includes two vertically arranged and opposing support columns 1 and two intermediate frames 11, each welded and fixed to the inner side of the support columns 1. The intermediate frames 11 are perpendicular to the support columns 1 and extend along the running direction of the conveyor belt 41. Guide rail supports 2 are fixed between the intermediate frames 11. The two ends of the guide rail supports 2 are welded to and perpendicularly fixed to the upper surfaces of the two intermediate frames 11. Idler assembly mounting frames are detachably fixed to the guide rail supports 2, and the rollers 4 of the idler assembly are mounted on the idler assembly mounting frames. When replacing the idler assembly, the idler assembly mounting frame can slide along the guide rail supports 2 and move out or into the guide rail supports 2 from the side of the support columns 1. That is, the idler assembly mounting frame can slide back and forth on the guide rail supports 2 along its length, and can be separated from or reconnected to the guide rail supports 2 through the ends of the guide rail supports 2.

[0039] Since the idler assembly mounting frame and the guide rail support 2 are detachably fixedly connected, when replacing the idler assembly, the connecting parts between the idler assembly mounting frame and the guide rail support 2 can be loosened first. Then the idler assembly mounting frame can slide along the guide rail support 2 and move out from the end of the guide rail support 2. Finally, remove the roller 4 from the idler assembly mounting frame, replace it with a new roller 4, move the replaced idler assembly mounting frame from the end of the guide rail support 2 into the guide rail support 2, and retighten the connecting parts to complete the replacement of the roller 4.

[0040] Furthermore, since the roller assembly mounting bracket needs to be moved in or out from the end of the guide rail support 2, the extension line of the guide rail support 2 will not intersect with the support column 1 and a certain gap will be left. This allows the roller assembly mounting bracket to be moved in or out from the side of the support column 1 onto the guide rail support 2. During actual assembly welding, it is necessary to avoid overlapping the roller assembly mounting bracket and the support column 1 on the intermediate frame 11.

[0041] By setting up a roller assembly mounting frame that is detachably and fixedly connected to the guide rail support 2, and the roller assembly mounting frame can slide and move in and out of the guide rail support 2, when replacing roller 4, it is only necessary to remove the entire roller assembly mounting frame from both ends of the guide rail support 2 by pulling it out before replacing roller 4. This design can avoid the risk of falling from height, reduce the lifting intensity of personnel, and the replacement of roller 4 can be completed while standing in the maintenance passage. The operation is simple, the efficiency is improved, the annual maintenance cost is reduced, the replacement time is saved, and the probability of safety accidents is reduced. It solves the problem in the background technology that replacing roller 4 requires completely disassembling the entire assembly structure or manually prying up the conveyor belt 41 on the roller assembly, which makes the replacement process of roller 4 complicated, the operation difficult, time-consuming and labor-intensive, and increases the probability of safety accidents.

[0042] Example 2: Based on Example 1, the roller assembly mounting frame and guide rail support 2 are optimized. The roller assembly mounting frame includes two sets of roller brackets 3 arranged on the left and right sides of the guide rail support 2 and not connected to each other. The two sets of roller brackets 3 stand opposite each other on the guide rail support 2. The rollers 4 of the roller assembly are mounted on the roller brackets 3. The two sets of roller brackets 3 can be moved out or in from both ends of the guide rail support 2. The guide rail support 2 includes two single guide rails 21 arranged parallel to each other in the horizontal direction. The two sets of roller brackets 3 are embedded between the two single guide rails 21 and arranged along their length.

[0043] Furthermore, such as Figures 1 to 2 As shown, the bottom of each set of idler roller brackets 3 consists of two sections of slide 30 that are snapped onto the guide rail support 2. Each set of idler rollers has two slide sections 30 connected parallel to two single guide rails 21 of the guide rail support 2. Each slide section 30 is detachably fixed to both ends of the surface of the corresponding single guide rail 21 via fasteners. Specifically, both ends of each single guide rail 21 are connected to the corresponding slide section 30 via bolts. The bolts pass downwards through the slide section 30 and the single guide rail 21, and are secured together with nuts. After removing the bolts, the slide section 30 can slide back and forth along its length on the corresponding single guide rail 21.

[0044] Preferably, a connecting plate 22 is fixed between the two single guide rails 21 to connect them, and the connecting plate 22 is provided with a positioning pin 23 that can pass through the roller bracket 3. The setting of the connecting plate 22 can not only improve the connection stability of the two single guide rails 21, but also install the positioning pin 23 for stabilizing the roller bracket 3.

[0045] Specifically, the connecting plate 22 is fixed perpendicularly to the center of the inner side of the single guide rail 21, and the connecting plate 22 connects the center of the inner side of the two single guide rails 21; the positioning pins 23 are fixed on both sides of the connecting plate 22 and perpendicular to the connecting plate 22, that is, extending in the length direction of the single guide rail 21. In this embodiment, two positioning pins 23 are provided on each side of the connecting plate 22, and the positioning pins 23 on both sides are symmetrically arranged. The connecting plate 22 is located at the center of the inner side of the single guide rail 21, which is more conducive to the connection of the positioning pins 23 with the roller bracket 3. The positioning pins 23 are arranged on both sides of the connecting plate 22 and perpendicular to it, which facilitates the simultaneous connection of two sets of roller brackets 3.

[0046] In a further preferred embodiment, the single guide rail 21 has several reinforcing ribs 24 inside, connecting the top and bottom surfaces of the single guide rail 21. The upper and lower ends of the reinforcing ribs 24 are welded and fixed to the top and bottom surfaces of the single guide rail 21, respectively. The reinforcing ribs 24 can improve the strength and load-bearing capacity of the guide rail support 2. In this embodiment, the reinforcing ribs 24 are respectively set in the middle and at both ends of the single guide rail 21. The surface of the single guide rail 21 is galvanized or coated with a high-temperature resistant ceramic layer, the surface of the roller bracket 3 is sprayed with an epoxy anti-corrosion coating, and a graphite lubricating layer is provided on the contact surface between the single guide rail 21 and the carriage 30.

[0047] The single guide rail 21 is galvanized, and the roller bracket 3 is coated with an epoxy anti-corrosion coating to prevent rust from forming on both, which would prevent the roller bracket 3 from sliding properly on the guide rail support 2. This design is suitable for use in high-humidity port environments. The contact surface between the single guide rail 21 and the carriage 30 is provided with a graphite lubrication layer, which reduces the operating force for pulling the roller bracket 3 to 40N, making it easier to move the roller bracket 3 in or out. The single guide rail 21 is coated with a high-temperature resistant ceramic layer, making it suitable for applications in high-temperature dusty metallurgical environments.

[0048] In a further preferred embodiment, the single guide rail 21 is made of channel steel, which is symmetrically bent into a channel shape by steel plate, with the slot opening facing outwards, meaning the slot openings of the two single guide rails 21 are opposite to each other. The carriage 30 is made of angle steel that matches the shape and size of the single guide rail 21. The angle steel is upside down on the single guide rail 21 and fits with it with a clearance. The two sections of carriage 30 in each set of idler roller brackets 3 are also fixed with a reinforcing plate 32 connecting the two sections. The reinforcing plate 32 is welded to the upper surface of the two sections of carriage 30 near the outer end and is fixed parallel to the upper surface. The reinforcing plate 32 is used to connect the two sections of carriage 30 in each set of idler roller brackets 3, so that the two sections of carriage 30 form a whole. By setting up a single guide rail 21 with a channel steel structure and a slide 30 made of angle steel that matches the structure of the single guide rail 21, the angle steel is upside down on the single guide rail 21. By cooperating with the reinforcing plate 32, the connection stability of each set of roller brackets 3 in the width direction is increased, and the slide 30 is prevented from being misaligned in the width direction of the single guide rail 21, which would be detrimental to the overall stability.

[0049] Example 3: Based on the above examples, a preferred design is made. Each set of idler roller brackets 3 has a side support 33 and a middle support 34 at both ends for mounting the idler roller assembly. Specifically, the outer end of the idler roller bracket 3 (the end closer to the support column 1) has a side support 33, and the inner end (the end farther from the support column 1) has a middle support 34. The lower parts of both the side support 33 and the middle support 34 extend into the carriage 30 (i.e., located between the two sections of the carriage 30) and are perpendicular to and welded to the inner surface of the carriage 30. The side support 33 and the middle support 34 are used to mount the rollers 4 of the idler roller assembly and connect the inner surfaces of the two sections of the carriage 30 within the same set of idler roller brackets 3, further improving the connection stability of the carriage 30.

[0050] The lower part of the central support 34 is provided with a connecting hole 35. The position and number of the connecting holes 35 are matched with the position and number of the positioning pins 23 on the connecting plate 22. When the idler bracket 3 is fixedly installed on the guide rail support 2, the movable end of the positioning pin 23 can pass horizontally through the connecting hole 35 to fix the position of the idler bracket 3. Thus, both ends of the idler bracket 3 are connected to the guide rail support 2 by positioning pins 23 and detachable fasteners, respectively. When the roller 4 needs to be replaced, it is only necessary to manually remove the fasteners on the side of the idler assembly mounting frame and pull out the idler bracket 3. The positioning pins 23 can then be disengaged from the central support 34, which is very convenient. After the replacement is completed, the idler bracket 3 can be firmly connected to the guide rail support 2.

[0051] Furthermore, such as Figure 2 and Figure 7 As shown, an adjustment groove 36 is provided at the top of the side support 33. The length direction of the adjustment groove 36 is consistent with the length direction of the conveyor belt 41. An adjustment plate 37 is provided on one side of the adjustment groove 36 and is fixed parallel to the side support 33. The outer end shaft of the idler group passes through the adjustment groove 36 and the adjustment plate 37 and can move back and forth within the adjustment groove 36 along the running direction of the conveyor belt 41 to achieve stepless adjustment of the forward tilt angle of the idler group. The adjustment range of the forward tilt angle is 0°-2°. The forward tilt angle is the angle between the axis of the idler group and the plane perpendicular to the running direction of the conveyor belt 41 when the idler group is installed, that is, the angle at which the idler group tilts forward.

[0052] Specifically, the adjusting plate 37 has mounting holes 38 on both sides of its surface. These mounting holes 38 are elongated holes arranged along the running direction of the conveyor belt 41. Bolts pass through these mounting holes 38 and the side support 33, and are connected with nuts to fix the side support 33 and the adjusting plate 37. The mounting holes 38 can accommodate different forward tilt angles and the corresponding connection positions on the adjusting plate 37 with the side support 33. Figure 8As shown, the top of the central support column 34 is provided with a slot 39. The idler assembly includes two rollers 4 respectively arranged on two sets of idler brackets 3. The outer end shafts of the two rollers 4 (i.e., the end of the central axis of the roller 4 near the support column 1) pass through the adjustment groove 36 and adjustment plate 37 of the side support column 33, and the inner end shafts (i.e., the end of the central axis of the roller 4 near the support column 1) pass through the slot 39 of the central support column 34. This structure can lock the rollers 4, stably install the idler assembly, and realize stepless adjustment of the forward tilt angle of the idler assembly, adapting to different working conditions, improving the correction capability, extending the life of the conveyor belt 41, and making it very simple and quick to replace the rollers 4, improving replacement efficiency. After the rollers 4 are installed, the formed trough angle β1 ranges from 10° to 15°.

[0053] Preferably, each set of idler roller brackets 3 is further provided with a handle post 31 between the side support post 33 and the middle support post 34. The handle post 31 is a steel pipe structure, and its two ends are welded and fixed to the side support post 33 and the middle support post 34, respectively. Each set of idler roller brackets 3 has two handle posts 31, and the roller 4 installed on each set of idler roller brackets 3 is located between two handle posts 31, and the two handle posts 31 are parallel to each other. By pulling the handle post 31, the idler roller bracket 3 can be pulled out along the guide rail support 2, and then the roller 4 can be replaced. This makes it easier to pull the idler roller bracket 3, further saving the time and effort spent pulling and pushing the idler roller bracket 3 in.

[0054] When it is necessary to replace roller 4, first remove the fasteners at both ends of the roller assembly mounting bracket, then hold the handle column 31 and pull out the two sets of roller brackets 3 from the corresponding ends of the guide rail support 2, then remove roller 4 from the side support column 33 and the middle support column 34, replace it with a new roller 4, then push the roller bracket 3 to slide it into the guide rail support 2 to the installation position, the positioning pin 23 in the guide rail support 2 extends into the connecting hole 35 of the middle support column 34, and finally tighten the fasteners to complete the replacement of roller 4. The entire replacement process can be operated by a single person and takes no more than 3 minutes.

[0055] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
