Description

Technical Field

[0001] This invention relates to the field of idler replacement technology, and more particularly to a conveyor belt idler replacement tool. Background Technology

[0002] Idler rollers support the conveyor belt and reduce friction during operation. They are an important component of the conveyor system. Idler rollers suffer wear and tear over time due to prolonged use, contamination from transported materials, and installation issues. Damage to idlers can cause the conveyor belt to shift or break, and in such cases, the idlers need to be replaced promptly.

[0003] Traditional methods of replacing idlers typically require the use of jacks or pry bars to forcefully lift a section of the conveyor belt. These tools can easily damage the conveyor belt. Therefore, there is an urgent need for a conveyor belt idler replacement tool. Summary of the Invention

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0032] Example 1 Reference Figures 1-2 According to the first embodiment of the present invention, a conveyor belt idler replacement tool is provided, including a lifting assembly 100, which includes a base 101, an air bladder 102 fixedly installed on the base 101, an air inflator valve fixedly disposed on the air bladder 102, and an air vent 103 fixedly disposed on the air bladder 102; and an unloading assembly 200 for unloading idlers after the conveyor belt is lifted, which includes a movable part 201 disposed on the base 101, a spreading part 202 disposed on the movable part 201, and a receiving seat 203 disposed on the base 101, the receiving part being used to receive the unloaded idlers.

[0033] The airbag 102 is shaped like a "U" with its upper surface being flat in the middle and sloping on both sides. The shape of the upper surface of the airbag 102 matches the lower surface of the conveyor belt, fully surrounding the bottom of the conveyor belt. The material composition of the airbag 102 is existing technology. The material of the airbag 102 is the same as that of the inflatable airbag 102 in amusement parks, which can bear a certain weight and has a certain strength.

[0034] Both the deflation nozzle 103 and the air inflator valve are existing technologies. The air inflator valve is used to connect to an air pump to facilitate the inflation of the air bag 102, while the deflation nozzle 103 allows workers to quickly deflate the air bag 102. Normally, the air bag 102 contains only a small amount of gas and is in a flattened state. When it is necessary to replace a roller on a support frame, this device is first placed next to the support frame and under the conveyor belt at that location. Then, the air pump is connected to the air inflator valve to inflate the air bag 102. The air bag 102 gradually inflates, simultaneously inflating the conveyor belt at that location. As the conveyor belt is gradually lifted, the airbag 102, being made of a softer material than ordinary crowbars, jacks, or other hard tools, is less likely to damage the conveyor belt surface. Furthermore, the airbag 102 has a larger contact area with the lower surface of the conveyor belt, resulting in lower pressure and further preventing damage to the conveyor belt surface. The larger contact area also reduces the probability of conveyor belt breakage during operation. After replacing the idler roller, the air release nozzle 103 is used to release air from the airbag 102, and the conveyor belt gradually moves back to its original position. Then, the air pump is removed from the air inlet nozzle 104, and the device is taken out.

[0035] In summary, when disassembling the idler roller, first open the corresponding support part 202 of the idler roller that needs to be replaced, then place this device under the conveyor belt near the corresponding position, and make the support rod 202d of the support part 202 extend under the corresponding idler roller. Then use the lifting component 100 to lift the conveyor belt near the support frame of the idler roller that needs to be replaced, and then control the movable part 201 to remove the idler roller. The idler roller falls into the receiving seat 203. When it reaches a certain position, the support part 202 automatically retracts, and then the movable part 201 retracts. Then, a new idler roller is installed.

[0036] Example 2 Reference Figures 3-5 This is the second embodiment of the present invention, which differs from the first embodiment in that: the movable part 201 includes a fixing member 201a fixedly disposed on the side of the base 101, a shaped groove 201b formed on the fixing member 201a, a rotating column 201c rotatably disposed on the bottom of the fixing member 201a, a movable rod 201d fixedly disposed on one end of the rotating column 201c, a movable column 201e rotatably disposed on the movable rod 201d, a movable rod 201f rotatably disposed on the movable column 201e, a connecting rod 201h rotatably disposed on the other end of the movable rod 201f, a movable member 201g rotatably disposed on the side of the connecting rod 201h, and a limiting post 201i fixedly disposed on the movable member 201g; the connecting rod 201h and the limiting post 201i are both movably disposed within the shaped groove 201b.

[0037] The irregular groove 201b includes a vertical groove 201b-1 and an arc groove 201b-2 connected to the vertical groove 201b-1; one end of the arc groove 201b-2 is connected to the center of the vertical groove 201b-1, the arc groove 201b-2 has one end of the vertical groove 201b-1 as its center point and half the length of the vertical groove 201b-1 as its radius, and the highest point of the arc groove 201b-2 is at the same height as the highest point of the vertical groove 201b-1; movable part 20 1g includes a vertical section 201g-1 and a bent section 201g-2 adjacent to the vertical section 201g-1. The connecting rod 201h is connected to the bottom end of the vertical section 201g-1. The limiting post 201i is fixedly installed at the connection between the vertical section 201g-1 and the bent section 201g-2. The limiting post 201i can only move in the upper half of the vertical groove 201b-1, and the connecting rod 201h can only move in the lower half of the vertical groove 201b-1 and the arc groove 201b-2.

[0038] The fixed part 201a, the irregular groove 201b, the movable part 201g, and the limiting post 201i are all provided with two sets of symmetrically distributed components. The connecting rod 201h connects the two movable parts 201g. The movable part 201 also includes a bracket 201j provided between the sides of the highest point of the bend of the two movable parts 201g, and two brackets 201k provided on both sides of the bracket 201j. The bracket 201j is connected to the bend section 201g-2. The bracket 201j corresponds to the lower middle roller, and the brackets 201k on both sides correspond to the other two inclined rollers at the same position.

[0039] Reference Figure 4 In the initial state: the connecting rod 201h is located at the bottom of the vertical groove 201b-1, the limiting post 201i is located at the middle point of the vertical groove 201b-1 and aligned with the bottom of the arc groove 201b-2, the vertical section 201g-1 is set parallel to the vertical groove 201b-1 and is in a vertical state, and the bracket 201j and bracket 201k are both located at the lowest point.

[0040] Phase 1: Control the rotating column 201c to rotate counterclockwise. The rotating column 201c can drive the movable rod 201d to rotate in the same direction. The movable rod 201d can then drive the movable rod 201f to move upward through the movable column 201e. Because the connecting rod 201h connected to the movable rod 201f is movably connected to the vertical groove 201b-1, the movable rod 201f can drive the connecting rod 201h to move upward. The connecting rod 201h can then drive the vertical section 20 of the movable part 201g. 1g-1 moves upward. Because the connecting rod 201h is located at the bottom of the vertical groove 201b-1, the connecting rod 201h can only move vertically upward. Therefore, the limiting post 201i set on the movable part 201g can also only move vertically upward. When the limiting post 201i moves upward to the highest point of the vertical groove 201b-1, the connecting rod 201h moves upward to the connection point between the arc groove 201b-2 and the middle part of the vertical groove 201b-1. In the first stage, the bracket 201j and the bracket 201k move vertically upward. Second stage: Due to the restriction of the vertical groove 201b-1, the limiting post 201i cannot move upwards further, and the connection between the vertical section 201g-1 and the bent section 201g-2 cannot move upwards further either. The movable rod 201d can still continue to rotate counterclockwise. Through the movable rod 201f, the movable part 201g is driven to rotate clockwise around the limiting post 201i. The connecting rod 201h enters the arc groove 201b-2, thereby driving the bracket 201j and bracket 201k to rotate clockwise, driving the spreading part 202 to move closer to the receiving groove, until the connecting rod 201h moves to the highest point of the arc groove 201b-2, and the rotating post 201c can no longer rotate.

[0041] To retract the lifting assembly 100 to its initial state, simply rotate the rotating column 201c in the opposite direction, following the same principle but with the reverse path, until the limiting column 201i returns to the midpoint of the vertical groove 201b-1, the connecting rod 201h returns to the bottom of the vertical groove 201b-1, and the brackets 201j and 201k also return to their original positions. Controlling the rotation of the rotating column 201c controls the brackets 201j and 201k to first move upwards and then rotate towards the receiving seat 203, before retracting them.

[0042] The remaining structure is the same as that in Example 1.

[0043] Example 3 Reference Figures 1-3 and Figures 6-9 This is the third embodiment of the present invention, which differs from the second embodiment in that: both bracket one 201j and bracket two 201k are provided with a spreading part 202; the spreading part 202 includes a mounting member 202a, a fixing post 202b fixedly disposed inside the mounting member 202a, a connecting block 202c rotatably disposed on the fixing post 202b, a support rod 202d fixedly disposed at one end of the connecting block 202c, a limiting post two 202e fixedly disposed on the upper side of the connecting block 202c, and a limiting post two opened inside the mounting member 202a. The system includes a groove 202f, a limiting frame 202g that slides within the limiting groove 202f, and a control rod 202g-1 that is fixedly mounted on the limiting frame 202g. The control rod 202g-1 extends out of the fixing member 201a, and the fixing member 201a has a channel for the control rod 202g-1 to move. The second limiting post 202e is movably mounted within the limiting frame 202g, and the limiting frame 202g can drive the second limiting post 202e to move. The three mounting members 202a are respectively fixedly mounted on the first bracket 201j and the second bracket 201k.

[0044] Both bracket 1 (201j) and bracket 2 (201k) have spaces to accommodate the movement of support rod 202d. Fixture 201a also has spaces within it for connecting block 202c and support rod 202d to move. The included angle between connecting block 202c and support rod 202d is 135 degrees. Limiting frame 202g can only slide left and right within limiting groove 202f. When limiting groove 202f is located at its leftmost position, support rod 202d is perpendicular to the surface of fixing component 201a, and perpendicular to bracket 1 (201j) and bracket 202k. When the limiting frame 202g slides to the other side of the limiting groove 202f, the limiting frame 202g can drive the limiting post 202e to move, thereby driving the connecting block 202c to rotate clockwise around the fixed post 202b, thereby driving the support rod 202d to rotate around the fixed post 202b. When the limiting frame 202g moves to the other side of the limiting frame 202g, the support rod 202d rotates ninety degrees and becomes parallel to the bracket 1 201j. Part of the support rod 202d is hidden in the corresponding bracket 1 201j or bracket 2 201k.

[0045] A spring 202h is fixedly installed between the limiting frame 202g and the mounting part 202a. One end of the spring 202h is located on the right side of the limiting frame 202g, and the other end is connected to the inner wall of the mounting part 202a. A portion of the spring 202h is located in the limiting groove 202f. A cylindrical space that can accommodate the spring 202h is provided in the fixing part 201a. A receiving block 202i is fixedly installed on the front side of the limiting frame 202g. A spring 202j is installed in the receiving block 202i. One end of the spring 202j is fixedly installed on the side of the limiting frame 202g, and a locking block 202k is fixedly installed on the other end of the spring 202j. A connecting groove 202l is opened on the mounting part 202a and communicates with the limiting groove 202f. The connecting groove 202l opens the fixing part 201a, allowing the locking block 202k to enter the connecting groove. The receiving block 202i is movably installed in the limiting groove 202f.

[0046] The width of the receiving block 202i and the limiting frame 202g together is the same as the width of the limiting groove 202f. The receiving block 202i can slide synchronously with the limiting frame 202g in the limiting groove 202f. One end of the spring 202j is fixedly connected to the side of the receiving block 202i, and the other end extends into the interior of the locking block 202k. The locking block 202k can be completely inserted into the receiving block 202i. The width of the connecting groove 202l is narrower than the width of the receiving block 202i to prevent the receiving block 202i from leaving the limiting groove 202f.

[0047] In summary, when the expansion part 202 is not used, the support rod 202d is parallel to the bracket 201j, the spring 202h pulls the limiting frame 202g to the rightmost side of the limiting groove 202f, the locking block 202k is completely inside the receiving block 202i, and the spring 202j is in a compressed state. When the expansion part 202 needs to be used, the control rod 202g-1 drives the limiting frame 202g to move to the left side of the limiting groove 202f, thereby opening the support rod 202d. The limiting frame 202g drives the receiving block 202i to move synchronously until... The receiving block 202i and the limiting frame 202g move together to the left side of the limiting groove 202f. The support rod 202d is perpendicular to the fixing member 201a. The support rod 202d is fully open. At this time, the locking block 202k is facing the connecting groove 202l. The second spring 202j can pop the locking block 202k out. The locking block 202k enters the connecting groove 202l. Then the control block 307c is released. Because the locking block 202k is restricted by the connecting groove 202l, the first spring 202h cannot pull the limiting frame 202g back to its original position. The support rod 202d is locked in the open state.

[0048] Three unlocking blocks 202m are fixedly installed on the receiving seat 203. The three unlocking blocks 202m can push the three locking blocks at different positions into the receiving block 202i. If the expansion part 202 on the bracket 1 201j or bracket 2 201k is opened, the locking block 202k will enter the connecting groove 202l. When the moving part 201 controls the bracket 1 201j and bracket 2 201k to move to the support rod 202d in a vertical state, the unlocking block 202m can enter the corresponding connecting groove 202l and push the locking block 202k into the receiving block 202i. The spring 1 202h can pull the limiting frame 202g and the receiving block 202i back to their original positions. The support rod 202d is retracted and the expansion part 202 returns to its initial state. The middle unlocking block 202m is lower in position, and the unlocking blocks 202m on both sides are the same height and symmetrical in position, and are higher than the middle unlocking block 202m.

[0049] Both brackets 201k and bracket 201j have a support section 202 in the middle. The support sections 202 on the two brackets 201k are symmetrically arranged. When the operator needs to replace any one or any two rollers or all three rollers, he only needs to pull the control rod 202g-1 of the corresponding support section 202 to make the locking block 202k enter the connecting groove 202l. The support rod 202d opens and enters under the roller. Then, the rotating column 201c is controlled to rotate, so that the support rod 202d moves upward first and pushes the roller upward away from the support frame. Then, the support rod 202d rotates in the direction of the receiving seat 203, driving the roller to roll into the receiving seat 203 and enter the receiving seat 203 until the support rod 202d is in a vertical state. The unlocking block 202m pushes the locking block 202k into the receiving block 202i, the support section 202 retracts, the rotating column 201c rotates in the opposite direction, and the movable part 201 returns to its original position.

[0050] The remaining structure is the same as that in Example 2.

[0051] Example 4 Reference Figure 1 and Figures 10-11 This is the fourth embodiment of the present invention. This embodiment differs from the second embodiment in that a control component 300 is also provided on the rotating column 201c. The control component 300 can further simplify the operator's steps and improve the original operating method. The control component 300 includes a fixed sleeve 301 fixedly disposed on the side of the fixing member 201a, an arc-shaped groove 302 formed on the fixed sleeve 301, a movable block 303 movably disposed within the arc-shaped groove 302, a gear 304 fixedly disposed on the outside of the movable block 303, and a gear 305 meshing with the gear 304. The gear 305 is longer and does not shift left or right. The gear 305 is fixedly disposed on the rotating column 201c, and the gear 304 is sleeved on the fixed sleeve 301.

[0052] The elastic part 306 includes a baffle 306a sleeved on the fixed sleeve 301 and a spring 306b fixedly disposed between the baffle 306a and the fixing member 201a; the control part 307 includes a stop post 307a fixedly disposed at one end of the fixed sleeve 301, a control tube 307b movably sleeved around the stop post 307a, a support block 307d fixedly disposed at one end of the stop post 307a, and a control block 307c fixedly disposed on the control tube 307b at the end away from the fixing member 201a; the baffle 306a is in contact with the gear 304, the control tube 307b is in contact with the gear 304, the gear 304 is located between the stop post 307a and the baffle 306a, and the support block 307d is fixedly disposed on the side of the base 101.

[0053] Reference Figure 1The control block 307c is located on the side easily accessible to the operator. When the operator needs to control the movable part 201 to remove the roller, they only need to push the control block 307c towards the fixed part 201a. The control block 307c will then drive the control tube 307b to push the gear 304 towards the fixed part 201a. Because the inside of the gear 304 is fixedly connected to the movable block 303, the movable block 303 is driven by the gear 304 to spiral counterclockwise along the arc groove 302. At the same time, gear 1 304 pushes baffle 306a to compress spring 306b. Gear 1 304 and movable block 303 spiral forward synchronously, thereby driving gear 2 305 to rotate clockwise, thereby driving rotating column 201c to rotate synchronously until movable part 201 moves to the corresponding position, the roller is removed, the spreading part 202 returns to its original position, the control block 307c is released, spring 306b rebounds, which can make gear 1 304 return to its original position, and gear 2 305 also rotate back to its original position.

[0054] The remaining structure is the same as that in Example 3.
