Description

Technical Field

[0001] This utility model relates to the technical field of plate conveyor maintenance equipment, specifically a portable belt roller replacement device. Background Technology

[0002] Plate conveyors are widely used in industrial settings such as mines. Their core transmission component is a series of idler roller assemblies arranged along the conveyor frame. An idler roller assembly typically includes an idler roller bracket fixed to the conveyor frame, a slot at the top of the bracket, an idler roller shaft interference-fitted into the slot, and an idler roller cylinder coaxially mounted on the idler roller shaft. During long-term operation, the idler roller cylinder is prone to wear due to material friction and impact, requiring periodic disassembly and replacement to ensure conveying efficiency.

[0003] In the existing technology, the disassembly of the idler roller cylinder mostly relies on manual pry bars or hoisting equipment: on the one hand, the idler roller shaft and the idler roller bracket are tightly fitted by interference, and manual prying can easily cause deformation of the idler roller shaft or damage to the bracket; on the other hand, the idler roller cylinder and the idler roller shaft are coaxially connected, and when the idler roller cylinder is directly pulled upward, it is easy to be unable to separate due to frictional resistance, which is time-consuming and laborious. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a portable belt idler replacement device. Through the structure of mechanical lifting and suspension, the idler cylinder and idler shaft in the idler section of the plate conveyor can be quickly disassembled and replaced. The operation process is more labor-saving and reduces the difficulty of operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A portable belt idler replacement device is disclosed, which is used for disassembling and replacing idler sections of a plate conveyor. The plate conveyor idler section includes a conveyor frame, multiple sets of idler brackets fixed on the conveyor frame, slots opened at the top of the idler brackets with upward openings, idler shafts interference-fitted into the slots, and idler cylinders coaxially rotatably mounted on the idler shafts. The core improvement is that the device includes a longitudinally arranged lifting frame, a lifting nut vertically fixed on the right side of the lifting frame, and a top rod coaxially installed in the lifting nut through a thread. A hanging bracket is connected to the bottom side of the lifting frame, and a horizontally arranged hanging rod is installed through the hanging bracket. Hooks evenly distributed on the left and right sides of the hanging bracket are suspended on the hanging rod.

[0006] By adopting the above solution, during replacement, since the hook includes an upper hook head, a hook body, and a lower hook head; the upper hook head is suspended on the body of the hanging rod, the lower hook head is suspended on the idler roller shaft, the top rod is pressed against the conveyor frame and rotated, the lifting frame gradually rises along the top rod under the action of the thread until the idler roller shaft and idler roller cylinder are pulled out together. It replaces manual prying with the threaded lifting structure, and a single person can complete the disassembly, reducing manpower consumption and reducing the difficulty of operation.

[0007] As a preferred embodiment of a portable belt roller replacement device, the top of the push rod is connected to a handle perpendicular to the push rod body, which makes it easy for the operator to hold and rotate the push rod, thus improving the ease of operation.

[0008] As a preferred embodiment of a portable belt roller replacement device, the bottom end of the push rod is rounded to avoid scratching the surface of the conveyor frame during rotation. It also reduces the rotational friction between the push rod and the conveyor frame, making it easier to operate.

[0009] In a preferred embodiment of a portable belt idler replacement device, the hanging rod includes a positioning rod in the middle and two suspension rods coaxially connected to the left and right ends of the positioning rod. The bottom of the positioning rod has an insertion hole, and the bottom of the hanging bracket is threaded through and fitted with an upward-facing self-locking screw that can be inserted into the insertion hole, enabling quick fixing and separation of the hanging bracket and the top rod. This facilitates the replacement of hanging rods of different lengths to meet the disassembly requirements of idler shafts of different lengths. The suspension rods are screw rods, and each suspension rod is threaded with two sets of limiting nuts. The upper hook head of the hook is suspended on the suspension rod body located between the two sets of limiting nuts. By adjusting the spacing of the limiting nuts, the position of the hook can be fixed to prevent the hook from sliding along the suspension rod, ensuring the suspension stability of the idler shaft.

[0010] In a preferred embodiment of a portable belt roller replacement device, a vertically arranged handle is connected to the left side of the lifting frame, allowing the operator to improve the stability of the lifting frame during lifting by holding the handle.

[0011] As a preferred embodiment of a portable belt roller replacement device, the lifting frame is internally connected with vertically arranged reinforcing ribs to improve the overall rigidity of the frame and prevent failure due to deformation under stress during the lifting process.

[0012] The beneficial effects of this utility model are: 1. Portable and efficient: When replacing, the hook consists of an upper hook head, a hook body, and a lower hook head. The upper hook head is suspended on the body of the hanging rod, and the lower hook head is suspended on the idler roller shaft. The top rod is pressed against the conveyor frame and rotated. The lifting frame gradually rises along the top rod under the action of the thread until the idler roller shaft and idler roller cylinder are pulled out together. The threaded lifting structure replaces manual prying, and a single person can complete the disassembly, reducing manpower consumption and reducing the difficulty of operation.

[0013] 2. Strong adaptability: The bottom of the positioning rod has an insertion hole, and the bottom of the hanging bracket is fitted with a self-locking screw facing upward and able to be inserted into the insertion hole through the thread, so as to realize the quick fixing and separation of the hanging bracket and the top rod, and facilitate the replacement of hanging rods of different lengths to meet the disassembly requirements of roller shafts of different lengths.

[0014] 3. High stability: The suspension rod is a screw rod, and each suspension rod is equipped with two sets of limit nuts by thread. The upper hook head of the hook is suspended on the suspension rod body located between the two sets of limit nuts. The position of the hook can be fixed by adjusting the distance between the limit nuts to prevent the hook from sliding along the suspension rod and ensure the suspension stability of the roller shaft.

[0015] 4. Protect the equipment: The round-headed push rod avoids scratching the conveyor frame and also reduces the rotational friction between the push rod and the conveyor frame, making it easier to operate. Attached Figure Description

[0020] like Figures 1 to 7 As shown, a portable belt idler replacement device is used for disassembling and replacing idler sections of a plate conveyor. The plate conveyor idler section includes a conveyor frame 1, multiple sets of idler brackets 2 fixed on the conveyor frame 1, a slot 3 opened at the top of the idler bracket 2 with its opening facing upward, an idler shaft 4 interference-fitted into the slot 3, and an idler cylinder 5 coaxially rotatably mounted on the idler shaft 4. The core improvement is that the device includes a longitudinally arranged lifting frame 6, a lifting nut 7 vertically fixed on the right side of the lifting frame 6, and a top rod 8 coaxially installed in the lifting nut 7 through a thread. A hanging bracket 9 is connected to the bottom side of the lifting frame 6, and a horizontally arranged hanging rod is installed through the hanging bracket 9. Hooks 10 evenly distributed on the left and right sides of the hanging bracket 9 are suspended on the hanging rod. During replacement, since the hook 10 includes an upper hook head, a hook body, and a lower hook head, the upper hook head is suspended on the rod body of the hanging rod, and the lower hook head is suspended on the idler roller shaft 4. The top rod 8 is pressed against the conveyor frame 1 and rotated. The lifting frame 6 gradually rises along the top rod 8 under the action of the thread until the idler roller shaft 4 and the idler roller cylinder 5 are pulled out together. The threaded lifting structure replaces manual prying, and a single person can complete the disassembly, reducing manpower consumption and lowering the difficulty of operation.

[0021] like Figures 4 to 7 As shown, the top of the push rod 8 is connected to a handle 11 that is perpendicular to the body of the push rod 8, which makes it easier for the operator to hold and rotate the push rod 8, thus improving the ease of operation.

[0022] like Figure 1 , Figures 4 to 7 As shown, the bottom end of the push rod 8 is rounded to avoid scratching the surface of the conveying frame 1 during rotation. It also reduces the rotational friction between the push rod 8 and the conveying frame 1, making it easier to operate.

[0023] like Figures 4 to 7As shown, the hanging rod includes a positioning rod 12 located in the middle and two suspension rods 13 coaxially connected to the left and right ends of the positioning rod 12. The bottom of the positioning rod 12 has an insertion hole, and the bottom of the hanging bracket 9 is threaded through and fitted with an upward-facing self-locking screw 14 that can be inserted into the insertion hole, so as to realize the quick fixing and separation of the hanging bracket 9 and the top rod 8, and facilitate the replacement of hanging rods of different lengths to meet the disassembly requirements of roller shafts 4 of different lengths. The suspension rod 13 is a screw rod, and each suspension rod 13 is threaded with two sets of limit nuts 15. The upper hook head of the hook 10 is suspended on the hanging rod 13 between the two sets of limit nuts 15. The position of the hook 10 can be fixed by adjusting the distance between the limit nuts 15 to prevent the hook 10 from sliding along the suspension rod 13 and ensure the suspension stability of the roller shaft 4.

[0024] Continue as Figures 4 to 7 As shown, a vertically arranged handle 16 is connected to the left side of the lifting frame 6. The operator can improve the stability of the lifting frame 6 during lifting by holding the handle 16.

[0025] Continue as Figures 4 to 7 As shown, the lifting frame 6 has vertically arranged reinforcing ribs 17 inside, which improve the overall rigidity of the frame and prevent failure due to deformation under stress during lifting. The working principle of this utility model: Preparations before lifting: Suspend the upper hook of hook 10 on the suspension rod 13 located between the two sets of limit nuts 15. The position of hook 10 can be fixed by adjusting the distance between the limit nuts 15 to prevent hook 10 from sliding along the suspension rod 13; suspend the lower hook on the idler roller shaft 4.

[0026] Lifting and disassembling (e.g.) Figure 3 As shown): The operator holds the handle 16 with their left hand and operates the rotating handle 11 of the rotating top rod 8 with their right hand. The operator rotates the top rod 8 by holding the handle 11. Due to the threaded engagement between the lifting nut 7 and the top rod 8, the lifting frame 6 moves upward along the top rod 8. The hanging bracket 9 rises synchronously with the lifting frame 6, and the hook 10 drives the roller shaft 4 to move upward until the roller shaft 4 is pulled out from the slot 3 of the roller bracket 2. At the same time, the roller cylinder 5 is synchronously pulled out because it is coaxially connected with the roller shaft 4.

[0027] Replacement complete: After disassembling the idler shaft 4 and idler cylinder 5, remove the worn idler cylinder 5, replace it with a new idler cylinder 5, and use a hammer to re-embed the idler shaft 4 into the slot 3 to replace the idler cylinder 5.
