Description

Technical Field

[0001] This invention relates to a portable conveyor belt roller replacement device, belonging to the field of coal and mineral material conveying technology. Background Technology

[0002] Coal mine underground transportation systems mostly use belt conveyors, and there are a large number of belt conveyors, so the number of idlers that need to be replaced every day is also huge.

[0003] Current technology is not comprehensive and has the following drawbacks:

[0004] Replacing conveyor belt idlers is a frequent task in coal mine production. The conventional method is to disassemble, install, and replace the idlers by lifting and carrying them on one's shoulders. In some areas with confined spaces or harsh environments, several people need to use a hand-operated hoist to lift the conveyor belt to complete the task. This is labor-intensive, inefficient, and can easily lead to personal injury accidents, posing safety hazards. Summary of the Invention

[0005] To address one of the aforementioned problems and in light of the shortcomings of the prior art, the present invention aims to solve the problem of cumbersome and laborious operation of conveyor belt rollers due to the weight of the conveyor belt. This device can ensure single-person operation and is convenient, simple, and efficient. Therefore, a portable conveyor belt roller replacement device is provided.

[0006] The portable tape roller replacement device of the present invention includes a top support mechanism and a bottom support mechanism. It is characterized in that it further includes a spacing adjustment mechanism between the top support mechanism and the bottom support mechanism, which is used to drive the top support mechanism to move closer to or further away from the bottom support mechanism, so as to reduce or increase the distance between the top support mechanism and the bottom support mechanism. The top support mechanism includes two support rods of equal length, which are overlapped at the center and perpendicularly intersected to form a cross support frame.

[0007] Preferably, the connection point between the spacing adjustment mechanism and the cross support frame is located at the central overlap point where the two support rods are connected.

[0008] Preferably, the bottom support mechanism includes a base supported on a support point, and a channel steel fixing frame for connecting with the spacing adjustment mechanism is installed on the base. The support point is located on the edge of the beam pressed by the tape roller.

[0009] Preferably, the spacing adjustment mechanism is a turnbuckle, including a turnbuckle body. The two ends of the turnbuckle body are respectively threaded with an upper screw A and a lower screw A. A rotating handle is welded to the middle of the turnbuckle body. By rotating the handle left and right, the upper screw A and the lower screw A can be simultaneously retracted or extended relative to the turnbuckle body. The ends of the upper screw A and the lower screw A away from the turnbuckle body are respectively connected to a cross support frame and a channel steel fixing frame.

[0010] Preferably, the rotating handle includes 2-3 sets of stop bars, all of which are arranged around the same vertical center line. The stop bars are configured to facilitate the rotation of the turnbuckle body relative to the upper screw A and the lower screw A.

[0011] Preferably, the rotating handle includes two sets of stops, both arranged around the same vertical center line and the included angle between adjacent stops is 180 degrees.

[0012] Preferably, both sets of support rods are connected to the same connecting plate. The spacing adjustment mechanism includes a central sleeve. The upper and lower ends of the central sleeve are respectively welded with an upper nut and a lower nut arranged concentrically with it. After the upper screw B is threadedly connected to the upper nut, it is inserted into the interior of the central double-layer sleeve. After the lower screw B is threadedly connected to the lower nut, it is also inserted into the interior of the central double-layer sleeve. The threads of the upper screw B and the lower screw B have opposite directions. The upper end of the upper screw B passes through the connecting plate and is fixedly connected to the connecting plate by two sets of corresponding locking nuts A. The middle part of the central double-layer sleeve is connected to a double-layer sleeve through a connecting ring. The middle part of the double-layer sleeve is sealed, and both its upper and lower ends have openings. An arc-shaped plate A and an arc-shaped plate B, which rotate and slide relative to the central sleeve, are inserted into the top opening of the double-layer sleeve. The upper ends of the arc-shaped plate A and the arc-shaped plate B are fixedly connected to the ends of the support rods of the cross support frame.

[0013] Preferably, a drive handle is welded to the outer wall of the double-layered sleeve.

[0014] Preferably, an arc-shaped plate B and an arc-shaped plate D, which rotate and slide relative to the central sleeve, are inserted into the bottom opening of the double-layer sleeve. The bottom ends of the arc-shaped plate B and the arc-shaped plate D are fixedly connected to the end of the connecting plate. The lower screw B passes through the connecting plate and is fixedly connected to the connecting plate by two sets of corresponding locking nuts B.

[0015] Preferably, an external force is used to push the drive handle, which drives the double-layer sleeve, connecting ring, and central sleeve to rotate. The central sleeve drives the upper nut and lower nut to rotate. The upper nut cooperates with the upper screw B, and the lower nut cooperates with the lower screw B, so as to extend or retract the upper screw B relative to the central sleeve. This is used to drive the top support mechanism to move closer to or away from the bottom support mechanism, so as to reduce or increase the distance between the top support mechanism and the bottom support mechanism. The arc plate A, arc plate B, arc plate D and arc plate D all cooperate with the double-layer sleeve to enhance the stability of the structure.

[0016] Preferably, the bottom end of the lower screw B is connected to the assembly of the foundation base and the channel steel fixing frame.

[0028] The present invention will now be further described with reference to the accompanying drawings:

[0029] The present invention will be further illustrated by specific embodiments below, but it is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0030] Example 1, as Figure 1 As shown, the portable tape roller replacement device includes a top support mechanism and a bottom support mechanism, and also includes a spacing adjustment mechanism between the top support mechanism and the bottom support mechanism for driving the top support mechanism closer to or further away from the bottom support mechanism, so as to reduce or increase the distance between the top support mechanism and the bottom support mechanism. The top support mechanism includes two support rods of equal length, which are overlapped at the center and perpendicularly intersected to form a cross support frame 1.

[0031] Furthermore, the connection point between the spacing adjustment mechanism and the cross support frame 1 is located at the central overlap point where the two support rods are connected.

[0032] Furthermore, the bottom support mechanism includes a base base 4 supported on a support point, and a channel steel fixing frame 5 for connecting with the spacing adjustment mechanism is installed on the base base 4. The support point is located on the edge of the beam pressed by the tape roller.

[0033] Furthermore, the spacing adjustment mechanism is a turnbuckle 3, including a turnbuckle body. The two ends of the turnbuckle body are respectively threaded with an upper screw A and a lower screw A. A rotating handle is welded to the middle of the turnbuckle body. By rotating the handle left and right, the upper screw A and the lower screw A can be simultaneously retracted or extended relative to the turnbuckle body. The ends of the upper screw A and the lower screw A away from the turnbuckle body are respectively connected to the cross support frame 1 and the channel steel fixing frame 5.

[0034] Furthermore, the rotating handle includes 2-3 sets of stop bars, all of which are arranged around the same vertical center line. The stop bars are configured to facilitate the rotation of the turnbuckle body relative to the upper screw A and the lower screw A.

[0035] Furthermore, the rotating handle includes two sets of stops, both arranged around the same vertical center line and the included angle between adjacent stops is 180 degrees.

[0036] The cross support frame 1 is connected to the upper ring of the basket spiral by a self-welded ring, which can rotate up and down to facilitate the lifting of belt surfaces at various angles. When in use, it is placed under the belt surface of the idler roller to be replaced to lift the belt surface.

[0037] The channel steel fixing frame 5 is welded to the base base 4. The channel steel fixing frame 5 can be fixed to the belt support tube during use, which is more secure.

[0038] The height adjustment handle 2 is welded to the turnbuckle 3. The height of the idler roller changing device is adjusted by rotating the height adjustment handle 2 in both directions. The self-locking function of the turnbuckle 3 thread is used to lift the belt surface.

[0039] By cleverly using turnbuckles, heavier belts can be lifted up, increasing the distance between the belt and the idler rollers, ensuring that the idler rollers can be easily removed. This can meet the replacement needs of intermediate idler rollers, side idler rollers, and lower idler rollers.

[0040] Example 2, as Figure 2-5 As shown, the portable tape roller replacement device includes a top support mechanism and a bottom support mechanism, and also includes a spacing adjustment mechanism between the top support mechanism and the bottom support mechanism for driving the top support mechanism closer to or further away from the bottom support mechanism, so as to reduce or increase the distance between the top support mechanism and the bottom support mechanism. The top support mechanism includes two support rods of equal length, which are overlapped at the center and perpendicularly intersected to form a cross support frame 1.

[0041] Furthermore, the connection point between the spacing adjustment mechanism and the cross support frame 1 is located at the central overlap point where the two support rods are connected.

[0042] Furthermore, the bottom support mechanism includes a base base 4 supported on a support point, and a channel steel fixing frame 5 for connecting with the spacing adjustment mechanism is installed on the base base 4. The support point is located on the edge of the beam pressed by the tape roller.

[0043] Furthermore, both sets of support rods are connected to the same connecting disc. The spacing adjustment mechanism includes a central sleeve 6, with an upper nut 9 and a lower nut 10 concentrically arranged at its upper and lower ends, respectively. The upper screw B7 is threadedly connected to the upper nut 9 and inserted into the central double-layer sleeve 12. The lower screw B8 is threadedly connected to the lower nut 10 and similarly inserted into the central double-layer sleeve 12. The threads of the upper screw B7 and the lower screw B8 have opposite directions. The upper end passes through the connecting plate and is fixedly connected to the connecting plate by two sets of corresponding locking nuts A. The middle part of the central double-layer sleeve 6 is connected to the double-layer sleeve 12 through the connecting ring 11. The middle part of the double-layer sleeve 12 is sealed, and both its upper and lower ends have openings. The top opening of the double-layer sleeve 12 is filled with an arc-shaped plate A13 and an arc-shaped plate C15 that rotate and slide relative to the central sleeve 6. The upper ends of the arc-shaped plate A13 and the arc-shaped plate C15 are fixedly connected to the end of the support rod of the cross support frame 1.

[0044] Furthermore, a drive handle 18 is welded to the outer wall of the double-layer sleeve 12.

[0045] Furthermore, an arc-shaped plate B14 and an arc-shaped plate D16 are inserted into the bottom opening of the double-layer sleeve 12, which rotate and slide relative to the central sleeve 6. The bottom ends of the arc-shaped plate B14 and the arc-shaped plate D16 are fixedly connected to the end of the connecting plate 17. The lower screw B8 passes through the connecting plate 17 and is fixedly connected to the connecting plate 17 by two sets of corresponding locking nuts B.

[0046] Furthermore, by pushing the drive handle 18 with external force, the drive handle 18 drives the double-layer sleeve 12, the connecting ring 11, and the central sleeve 6 to rotate. The central sleeve 6 drives the upper nut 9 and the lower nut 10 to rotate. The upper nut 9 cooperates with the upper screw B7, and the lower nut 10 cooperates with the lower screw B8, so as to extend or retract the upper screw B7 and the lower screw B8 relative to the central sleeve 6. This is used to drive the top support mechanism to move closer to or away from the bottom support mechanism, so as to reduce or increase the distance between the top support mechanism and the bottom support mechanism. The arc plate A13, arc plate B14, arc plate C15, and arc plate D16 all cooperate with the double-layer sleeve 12 to enhance the stability of the structure.

[0047] Furthermore, the bottom end of the lower screw B8 is connected to the assembly of the foundation base 4 and the channel steel fixing frame 5.

[0048] The portable tape roller replacement device of the present invention solves the problem of tedious and laborious operation when using tape rollers due to the weight of the tape. The device can be operated by a single person and is easy, simple and efficient to operate.

[0049] The portable tape roller replacement device of the present invention has a simple structure, is easy to use and operate, and can be used without special training. At the same time, the device is lightweight and can be carried by employees. One person can operate and complete the disassembly and assembly, saving time and effort.

[0050] The portable conveyor belt roller replacement device described in this invention reduces the manpower required for roller replacement, greatly improves labor efficiency, avoids the need to use a hand chain hoist to lift the conveyor belt, eliminates safety hazards, reduces the labor intensity of employees, saves time, and improves labor efficiency, thus showing good market prospects.
