[0026] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0027] A belt conveyor, also known as a belt conveyor, consists of an endless conveyor belt that wraps around a drive drum and a redirecting drum. Several idlers are installed between the two drums for support, and the material is transported by the friction between the drive drum and the belt. During long-term material transport, the idler rollers or roller supports are prone to damage and need to be replaced.

[0028] Currently, most replacement of rollers or idlers involves manually prying up the belt before replacement. This method is inefficient, labor-intensive, and poses safety hazards, such as the belt slipping, falling, or injuring personnel. Furthermore, the conveyor belt must be stopped before replacement, affecting production. Moreover, for large conveyors, it is impossible to lift the belt manually and perform the replacement operation.

[0029] In view of this, an embodiment of the present invention provides a quick-change device for belt conveyor rollers, which can solve the above problems, and will be described in detail below.

[0030] Please refer to Figures 1 to 3The belt conveyor roller quick change device includes a base plate 1, a top plate 2, and an idler roller assembly 3. A lifting assembly 10 is provided on the base plate 1. The top plate 2 is located above the base plate 1, and the middle part of the top plate 2 is connected to the lifting assembly 10. The lifting assembly 10 can drive the top plate 2 to move up and down. The idler roller assembly 3 is located on the upper part of the top plate 2. The idler roller assembly 3 includes a left inclined idler roller 30, a right inclined idler roller 31, and a horizontal idler roller 32. The horizontal idler roller 32 is located between the left inclined idler roller 30 and the right inclined idler roller 31. The left inclined idler roller 30 and / or the right inclined idler roller 31 can slide along the chute 20.

[0031] The lifting assembly 10 drives the top plate 2 and the roller assembly 3 on the top plate 2 to move upward. The roller assembly 3 contacts the belt 6 and partially lifts the belt 6, providing operating space for replacing the damaged roller 33 or roller support 34. The lifting assembly 10 replaces manual prying, reducing the labor intensity of manual labor and eliminating the safety hazards associated with manual prying. The roller assembly 3 includes a left inclined roller 30, a right inclined roller 31, and a horizontal roller 32. The left inclined roller 30, the right inclined roller 31, and the horizontal roller 32 work together to maintain the original grooved transport state of the belt 6 during lifting. The partial lifting of the belt 6 without changing its original grooved shape does not affect the transport function. Therefore, the roller 33 or roller support 34 can be replaced without stopping the machine. The top plate 2 is also provided with a chute 20. The chute 20 is opened along the width direction of the belt 6. The left inclined idler 30, the right inclined idler 31, or the left inclined idler 30 and the right inclined idler 31 can slide along the chute 20 to change the distance between them and the horizontal idler 32, thereby changing the support width of the entire idler assembly 3. This is beneficial for the idler assembly 3 to adapt to belts 6 of different widths and to facilitate the lifting of belts 6 of different widths. It can be used for the replacement of rollers 33 in belt conveyors of various specifications.

[0032] In this embodiment, both the base plate 1 and the top plate 2 are rectangular steel plates, which can be made of high-strength alloy steel (Q345-B) and are not easily deformed during use. The two rectangular steel plates are spaced apart and parallel to each other. A support column 4 is provided between the top plate 2 and the base plate 1. The bottom end of the support column 4 is fixedly connected to the base plate 1, and the top plate 2 is movably connected to the support column 4. For example, the bottom end of the support column 4 is welded to the upper surface of the base plate 1, and a guide sleeve hole 21 is provided on the top plate 2. The size and shape of the guide sleeve hole 21 are adapted to the support column 4, and the top end of the support column 4 passes through the guide sleeve hole 21, so that the top plate 2 can move up and down along the support column 4 without tilting. The support column 4 can be made of H-beam steel, and the guide sleeve hole 21 can be set in a rectangular hole. Of course, the top end of the support column 4 can also be directly connected to the top plate 2. In this case, the support column 4 is a telescopic column. When the lifting assembly 10 lifts the top plate 2, the support column 4 extends; when the lifting assembly 10 retracts, the support column 4 retracts.

[0033] To ensure high stability during use, at least four support columns 4 are provided, which are symmetrically arranged on the left and right sides of the base plate 1. Similarly, the number of lifting components 10 can also be two or more, with multiple lifting components 10 evenly distributed along the middle of the top plate 2. During use, multiple lifting components 10 simultaneously lift the top plate 2.

[0034] Optionally, the guide sleeve hole 21 is also provided with a guide plate, which is set perpendicular to the top plate 2. This way, the top plate 2 will not directly rub against the support column 4 during the up and down movement, thereby reducing jamming during movement and preventing the top plate 2 from tilting during the movement.

[0035] refer to Figure 4 To prevent the top plate 2 from suddenly falling and causing a safety accident during use, multiple locking holes can be provided on the support column 4. These locking holes are arranged along the height of the support column 4. After the lifting assembly 10 lifts the top plate 2 to a predetermined height, a locking element 5 can be inserted into the locking hole below the top plate 2 to prevent the top plate 2 from suddenly falling. The locking element 5 can be a high-strength pin with a pin hole 50. A safety pin 51 can be vertically inserted into the pin hole 50 to prevent the pin from slipping out of the locking hole.

[0036] Continue to refer to Figure 2 The top plate 2 has two grooves 20 on its upper part. The two grooves 20 are on the same straight line and are not connected. The two grooves 20 are located on the left and right sides of the top plate 2, respectively. A left inclined roller 30 is set in the left groove 20 and can slide along the left groove 20. A right inclined roller 31 is set in the right groove 20 and can slide along the right groove 20. A horizontal roller 32 is fixedly set between the two grooves 20 and is on the same straight line as the two grooves 20. When the left inclined roller 30 and / or the right inclined roller 31 are slid, the width of the entire roller assembly 3 can be changed, thereby adapting to belts 6 with different bandwidths. In this embodiment, the cross-sectional shape of the groove 20 is adapted to the inclined roller and can be set to a rectangular cross-section, a T-shaped cross-section, etc.

[0037] In other embodiments, the sliding of the left inclined roller 30 and the right inclined roller 31 can also be achieved by other means such as slide rails and rollers, and there is no limitation on this.

[0038] Continue to refer to Figure 3The idler assembly 3 includes a left inclined idler 30, a right inclined idler 31, and a horizontal idler 32. The left inclined idler 30 and the right inclined idler 31 have a symmetrical structure. Each of the left inclined idler 30, the right inclined idler 31, and the horizontal idler 32 includes a roller support 34 and a roller 33. The roller 33 is rotatably connected to the roller support 34. The roller support 34 can be formed by welding high-strength steel pipes. The form of the roller support 34 can refer to the structure in the prior art, which will not be described in detail here. It is worth mentioning that the roller surface of the roller 33 is higher than that of the roller support 34. The roller 33 is in direct contact with the belt 6. In order to improve the service life of the roller 33, a wear-resistant layer is provided on the outer wall surface of the roller 33 to improve wear resistance; for example, the outer wall of the roller 33 is coated with a wear-resistant ceramic coating.

[0039] Continue to refer to Figure 1 The lifting assembly 10 can be a hydraulic system, which includes a jack 101 and a hydraulic pump station 102. The jack 101 and the hydraulic pump station 102 are connected by oil pipes. The piston rod of the jack 101 is connected to the top plate 2 by a ball joint to adapt to the angle of the top plate 2. The hydraulic pump station 102 can be operated manually or by electric remote control. Specifically, a ball joint seat is welded to the lower center of the top plate 2, and this ball joint seat is connected to the end of the piston rod of the jack 101.

[0040] In other embodiments, the lifting assembly 10 may also be a pneumatically driven structure, a lead screw structure, or a scissor structure, and the form of the lifting assembly 10 is not limited.

[0041] When the device is placed on the frame of the belt conveyor system 6, the height of the device is less than the distance from the frame to the belt 6. When the device is placed on the frame of the belt conveyor system 6, the base plate 1 needs to be fixed to the frame.

[0042] Optionally, the base plate 1 is provided with anchor bolt holes, and the frame is also provided with bolt holes. The base plate 1 is fixed to the frame by inserting bolts into the bolt holes, which plays a role in stable connection.

[0043] Of course, a locking structure such as a buckle can also be fixed to the base plate 1 to securely connect the base plate 1 to the frame. The specific form of the locking structure can be either a commercially available locking device or a custom design; there are no restrictions on this.

[0044] The belt conveyor roller quick replacement device of this utility model embodiment can adapt to belts 6 with different bandwidths because the left inclined idler roller 30 and the right inclined idler roller 31 can be slidably adjusted. It can be used when changing rollers 33 or roller supports 34 on belt conveyors of different specifications. The device uses a hydraulic system to lift the belt 6, eliminating the need for manual prying, reducing labor intensity, eliminating safety hazards, and improving replacement efficiency. Replacement operations can still be performed without stopping the machine, without affecting normal production.

[0045] Instructions for use of the belt conveyor roller quick-change device according to this utility model embodiment: First, transport the device to the area below the roller 33 to be replaced, and fix the base plate 1 to the frame. The hydraulic pump station 102 pumps out hydraulic oil to raise the piston rod of the jack 101. The jack 101 lifts the top plate 2 and causes the roller 33 to raise the belt 6 to a suitable height. Insert the locking piece 5 into the locking hole closest to the lower surface of the top plate 2, and insert the safety pin 51 into the pin hole 50 of the locking piece 5 to lock it. Remove the damaged or old roller 33 or roller bracket 34, and install a new roller 33 or roller bracket 34. Pull out the safety pin 51, remove the locking piece 5, the hydraulic pump station 102 returns oil, the piston rod of the jack 101 moves down, the top plate 2 and the roller assembly 3 on the top plate 2 move down, the belt 6 resets, and the device is removed.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
