Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyor equipment, and in particular to a belt conveyor with quick-change idler rollers. Background Technology

[0002] In mines, ports, power plants, and various industrial production lines, belt conveyors are the core equipment for continuous material transport. Idler rollers, as one of the most critical components of belt conveyors, support the conveyor belt and the weight of the materials, ensuring stable belt operation. Due to the long-term exposure to loads, wear, and environmental corrosion, idler rollers are among the most easily damaged parts of the conveyor and require frequent replacement.

[0003] In practical applications, the process of changing idlers in existing belt conveyors is extremely cumbersome and inefficient, and suffers from the following problems: Usually, the machine needs to be stopped first, and the protective devices on both sides of the conveyor belt and even part of the frame structure need to be manually disassembled before the damaged idler rollers can be accessed for replacement. This process is not only labor-intensive and time-consuming, which seriously affects production efficiency, but also poses safety risks for working at height. The presence of direct bolt fixing or welding makes actual disassembly difficult and also poses a problem to the overall stability of the equipment, resulting in numerous inconveniences.

[0004] Therefore, this utility model provides a belt conveyor with quick roller replacement. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a belt conveyor structure that enables quick, safe and convenient replacement of idlers, so as to minimize downtime and reduce maintenance costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a belt conveyor with quickly replaceable idlers, including a bottom positioning plate. The bottom positioning plate is equipped with equidistantly distributed support frames on its top. Each of the support frames is fixedly connected to a fixed steel rail. Two fixed steel rails are symmetrically distributed. A fitting pad is installed on the top of the two fixed steel rails. Two symmetrically distributed conveyor belt side baffles are installed on the top of the fitting pad. A second auxiliary positioning plate is installed between the bottom positioning plate and the bonding pad, and is equidistantly and symmetrically distributed. A connecting rod is rotatably connected between the two second auxiliary positioning plates on the same side. A third support roller is fixedly connected to both ends of the connecting rod. A rotating disk is fixedly connected to the outer side of the two third support rollers. The rotating disk is located below the bonding pad. The ends of the two third support rollers that are far apart extend into the interior of the second auxiliary positioning plate and are rotatably connected to the second auxiliary positioning plate. A first auxiliary positioning plate is installed on one side of the second auxiliary positioning plate and on the top of the fixed rail, and is equidistantly distributed. The first and second auxiliary positioning plates are staggered. A connecting horizontal plate is fixedly connected between the two first auxiliary positioning plates. A second support plate is fixedly connected to the top of the connecting horizontal plate. A first support roller is rotatably connected to one side of the second support plate. A second support roller is installed between the two first support rollers. The top of each of the first auxiliary positioning plates is threaded with symmetrically distributed third positioning bolts that extend into the interior of the fixed rail. The first auxiliary positioning plate and the fixed rail are positioned and installed by multiple third positioning bolts, which facilitates the quick disassembly and assembly of equipment such as the first support roller and the second support roller for corresponding replacement.

[0007] In a preferred embodiment, a drive motor is installed on one side of each of the second auxiliary positioning plates. The output end of the drive motor is fixedly connected to the corresponding third support roller. Symmetrically distributed fifth positioning bolts extending into the interior of the fixed rail are threaded onto the top of each of the second auxiliary positioning plates. Multiple fifth positioning bolts allow for quick installation of the second auxiliary positioning plates and the fixed rail, facilitating subsequent maintenance and disassembly. Two symmetrically distributed shock-absorbing mounting brackets are installed on the top of the fixed rail. An internal limiting frame is fixedly connected to the top of each shock-absorbing mounting bracket. An electric telescopic rod is fixedly connected inside the internal limiting frame, and the output end of the electric telescopic rod passes through the internal limiting frame and is fixed. A push rod is connected, and a top support plate is fixedly connected to one end of the push rod. The top support plate is located below the fitting pad. Two symmetrically distributed limit sliders are slidably connected inside the internal limit frame. A support seat is fixedly connected to one side of each of the two limit sliders, and the top of each of the two support seats is fixedly connected to the top support plate. Two limit grooves are opened inside the internal limit frame to cooperate with the limit sliders. When the electric telescopic rod is running, it drives the push rod to move upward, which in turn drives the two conveyor belt side baffles and the fitting pad to move upward. At this time, the two limit sliders will slide inside the internal limit frame to limit the movement trajectory, thereby cooperating with the subsequent normal reset.

[0008] In a preferred embodiment, two symmetrically distributed first support plates are fixedly connected to the top of the connecting horizontal plate and below the first support roller. The two sides of the second support roller are respectively connected to the corresponding first support plates. Rotating rods are rotatably connected inside each of the second support rollers. The first and second support plates are used to support and install the first and second support rollers. Fourth positioning bolts that cooperate with the limiting of the first support rollers are installed on the outer side of each of the second support plates. Bottom limiting plates are installed at the bottom of the fixed rails and below the connecting rod. Multiple bottom limiting plates are used to provide auxiliary support for the two fixed rails. A wireless transceiver is fixedly connected to the top of the shock-absorbing mounting frame and to one side of the electric telescopic rod. A main control board is fixedly connected inside the wireless transceiver, and a control chip is fixedly connected to the outer side of the main control board. The electric telescopic rod, wireless transceiver, and drive motor are all electrically connected to the control chip. The control chip is used to control the operation of the electric telescopic rod, wireless transceiver, and drive motor, realizing unified management of the power equipment.

[0009] In a preferred embodiment, the bottom of each support frame is fixedly connected to a bottom reinforcement seat. The top of the bottom reinforcement seat and both sides of the support frame are threaded with first positioning bolts extending to the inner wall of the bottom positioning plate. The support frame and the bottom positioning plate are positioned and installed by the cooperation of multiple first positioning bolts and bottom reinforcement seats, thereby improving the operational stability of the overall conveyor equipment.

[0010] In a preferred embodiment, both sides of the internal limiting frame are fixedly connected with equidistant reinforcing side plates. The bottom of each reinforcing side plate is fixedly connected to a shock-absorbing mounting frame. The internal thread of the shock-absorbing mounting frame is connected with equidistant second positioning bolts that extend into the corresponding fixed rails. The shock-absorbing mounting frame and the fixed rails are connected by multiple second positioning bolts, and the internal limiting frame and the shock-absorbing mounting frame are reinforced by multiple reinforcing side plates, thereby ensuring the stability of the equipment support.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By setting a bottom positioning plate, conveyor belt side baffles, and shock-absorbing mounting brackets, the conveyor belt is placed on the contact pad surface during use. A roller group is formed by the first auxiliary positioning plate, connecting cross plate, first support clamping plate, and second support clamping plate. The first and second support rollers are installed on this roller group by fasteners such as the fourth positioning bolt, forming the main roller group for supporting the straight section of the conveyor belt. It is connected to the fixed rail by the third positioning bolt. When replacement is needed, only a few bolts need to be loosened to remove the entire roller group. Another roller group is formed by the second auxiliary positioning plate, connecting rod, etc., mainly used to install the third support roller located at the turning point or special part of the conveyor. The drive motor can drive the rotation of this roller to achieve the anti-deviation effect. It is fixed to the fixed rail by the fifth positioning bolt. The fixed position provides ample and safe operating space for replacing the idlers below. When internal equipment needs to be replaced, instructions are received via wireless transceiver or local operation to initiate the lifting procedure, raising the conveyor belt. Workers loosen the third positioning bolts to remove the component, including the damaged idler, from the fixed rail. The repaired idler component is then reinstalled onto the fixed rail, and the corresponding bolts are tightened. Finally, the electric telescopic rod is retracted, and the conveyor belt smoothly descends onto the new idler, completing the replacement. The support frame and bottom positioning plate are positioned and installed using multiple first positioning bolts and bottom reinforcement seats, thereby improving the overall operational stability of the conveyor equipment. Multiple reinforced side plates reinforce the internal limit frame and shock-absorbing mounting frame, ensuring the stability of the equipment support. Attached Figure Description

[0019] In this scheme, a wireless transceiver 32 is fixedly connected to the top of the shock-absorbing mounting bracket 3 and to one side of the electric telescopic pole 31. A main control board is fixedly connected inside the wireless transceiver 32, and a control chip is fixedly connected to the outside of the main control board.

[0020] Going further, such as Figures 1-4As shown, in this scheme, the bottom of the support frame 11 is fixedly connected to a bottom reinforcement seat 12.

[0022] Working principle: like Figures 1-5 As shown: By setting up a bottom positioning plate 1, a conveyor belt side baffle 2, and a shock-absorbing mounting bracket 3, the conveyor belt is placed on the surface of the fitting pad 21 during use. A roller group is formed by the first auxiliary positioning plate 4, the connecting cross plate 41, the first support clamping plate 42, and the second support clamping plate 43. The first support roller 44 and the second support roller 45 are installed on this roller group by fasteners such as the fourth positioning bolt 47, forming the main roller group for supporting the straight section of the conveyor belt. It is connected to the fixed rail 14 by the third positioning bolt 46.

When internal equipment needs to be replaced, the lifting procedure is initiated via a wireless transceiver 32 or local operation, lifting the conveyor belt. Workers can then loosen the third positioning bolt 46 to remove the component, including the damaged idler roller, from the fixed rail 14 and reinstall the repaired idler roller component. Install it onto the fixed rail 14, tighten the corresponding bolts, and finally control the electric telescopic rod 31 to retract. The conveyor belt smoothly lands on the new idler, completing the replacement. The control chip is used to control the operation of the electric telescopic rod 31, the wireless signal transceiver 32, and the drive motor 55, realizing unified management of the power equipment. The support frame 11 and the bottom positioning plate 1 are positioned and installed by multiple first positioning bolts 13 and bottom reinforcement seats 12, thereby improving the overall operational stability of the conveyor equipment. The internal limit frame 39 and the shock-absorbing mounting frame 3 are reinforced and connected by multiple reinforcement side plates 37, thereby ensuring the stability of the equipment support.
