Description

Technical Field

[0001] This utility model belongs to the technical field of sintering equipment in the metallurgical industry, and specifically relates to a portable belt roller changer. Background Technology

[0002] In sintering systems of the metallurgical industry, belt conveyors are one of the core pieces of equipment for material transportation, and idlers, as an important component of belt conveyors, play a crucial role in supporting the belt and materials. However, due to long-term operation and harsh working environments (such as high temperature, high dust, heavy load, etc.), idlers are prone to wear, jamming, and even breakage, requiring regular replacement to ensure the normal operation of the system.

[0003] Currently, when replacing belt idlers in sintering systems in the metallurgical industry, one worker typically uses a lever to lift the belt, disengaging it from the idler, while another worker replaces the idler. This method is extremely physically demanding and cannot effectively guarantee safety.

[0004] To address the aforementioned issues, existing technologies lack an efficient, safe, and portable idler roller replacement device. Utility Model Content

[0005] This invention provides a portable belt idler changer to address the lack of an efficient, safe, and portable idler replacement device in the prior art.

[0006] This utility model provides a portable belt roller changer, including a base, an upper support seat, a support rod, and a stop arm;

[0007] The base and the upper support are long strip-shaped structures. The upper support is located directly above the base, and both ends of the upper support are connected to the base through jacks.

[0008] The jack includes a ball screw, four connecting rods, and ball nuts; the four connecting rods are hinged end to end in sequence to form a closed lifting structure. The upper and lower ends of the lifting structure are hinged to the upper support and the base respectively, and the left and right ends of the lifting structure are connected to the ball screw through ball nuts; rotating the ball screw makes the lifting structure form a straight folded state or a diamond-shaped support state.

[0009] The upper support base is hinged to one end of two support rods on both sides of its center. The middle of the support rod is hinged to one end of the stop arm. The top of the upper support base has equally spaced slots at both ends. The end of the stop arm away from the support rod is engaged with the slot.

[0010] Compared with existing technologies, the advantages of this utility model are as follows: through the coordinated design of the base, upper support seat, support rod, and stop arm, effective support for the belt and rapid replacement of the idler rollers are achieved. The jack employs a lifting structure composed of a ball screw and four connecting rods, which can switch the lifting structure between a folded state and a supported state by rotating the ball screw. This easily lifts the belt and disengages it from the idler rollers, significantly reducing the labor intensity of workers, improving operational efficiency, and avoiding the safety hazards of manually lifting the belt. It is suitable for the complex working environment of sintering systems in the metallurgical industry.

[0011] Furthermore, the upper and lower ends of the lifting structure are hinged to the upper support seat and the base through pins, the upper support seat and the support rod are hinged to each other through pins, and the support rod and the stop arm are hinged to each other through pins.

[0012] Furthermore, the base has a chamber for accommodating the jack.

[0013] Furthermore, the upper support also has a chamber for accommodating the jack.

[0014] Furthermore, a hexagonal head is fixedly connected to one end of the ball screw. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1This utility model provides a portable belt roller changer, including a base 1, an upper support 4, support rods 5, and a stop arm 6. The base 1 and the upper support 4 are elongated plate structures. The upper support 4 is located directly above the base 1, and both ends of the upper support 4 are connected to the base 1 via jacks. The jacks include a ball screw 2, four connecting rods 3, and ball nuts 8. The four connecting rods 3 are sequentially hinged end to end to form a closed lifting structure. The upper and lower ends of the lifting structure are hinged to the upper support 4 and the base 1, respectively, and the left and right ends of the lifting structure are connected to the ball screw 2 via ball nuts 8. Rotating the ball screw 2 causes the lifting structure to form a straight folded state or a diamond-shaped support state. The center sides of the upper support 4 are hinged to one end of two support rods 5, and the middle part of the support rods 5 is hinged to one end of the stop arm 6. The top two ends of the upper support 4 are provided with equally spaced slots, and the end of the stop arm 6 away from the support rods 5 is engaged with the slots.

[0020] The portable belt idler changer provided by this utility model, through the cooperative design of the base 1, upper support seat 4, support rod 5, and stop arm 6, achieves effective support for the belt and rapid replacement of the idler. The jack employs a lifting structure composed of a ball screw 2 and four connecting rods 3, which can switch between a folded state and a supported state by rotating the ball screw 2. This easily lifts the belt and disengages it from the idler, significantly reducing the labor intensity of workers, improving operational efficiency, and avoiding the safety hazards of manually lifting the belt. It is suitable for the complex working environment of sintering systems in the metallurgical industry.

[0021] Optionally, the upper and lower ends of the lifting structure are hinged to the upper support seat 4 and the base 1 via pins 7, the upper support seat 4 is hinged to the support rod 5 via pins 7, and the support rod 5 is hinged to the stop arm 6 via pins 7.

[0022] By further defining the connection method between the lifting structure, upper support 4, support rod 5, and stop arm 6, the flexible movement between the components is further ensured, enhancing the stability and reliability of the structure. The pin 7 connection is easy to install and disassemble, convenient for maintenance and replacement, and can withstand large loads, ensuring the safety and durability of the device when lifting the belt.

[0023] Furthermore, the base 1 is provided with a chamber for accommodating the jack, and the upper support is also provided with a chamber for accommodating the jack.

[0024] By adding a chamber, the jack can be stored inside the base 1, making the device more compact in the folded state, facilitating carrying and storage. At the same time, the chamber design also protects the jack's critical components from damage during transportation or storage, extending the device's lifespan. It can be understood that, in the folded state, part of the jack is placed in the chamber of the upper support 4, and the other part is placed in the chamber of the base 1.

[0025] In one specific embodiment, a hexagonal head is fixedly connected to one end of the ball screw 2.

[0026] The hexagonal head design allows the ball screw 2 to be operated with a standard hex wrench or adjustable wrench, providing greater torque transmission capacity and making it suitable for applications requiring greater force. Furthermore, the hexagonal head's simple structure and ease of manufacture, along with compatibility with common tools, enhance the device's applicability and ease of operation, making it particularly suitable for use in confined or complex working environments.

[0027] The portable belt idler changer provided by this utility model is in a folded state when idle. In use, place the portable belt idler changer under the belt of the belt conveyor, lift the support rod 5 so that the support rod 5 is at the same tilt angle as the belt, lock the stop arm 6 into the slot of the upper support seat 4, rotate the ball screw 2 so that the ball screw 2 drives the lifting structure to form a prismatic support state, rise until the belt and idler are separated, remove the damaged idler, replace it with a new idler, and then rotate the ball screw 2 again to return to the folded state.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
