Description

Technical Field

[0001] This utility model relates to the field of roller conveyor technology, and in particular to a single-row power roller support that can be quickly disassembled and assembled. Background Technology

[0002] Powered roller conveyors are indispensable core material handling equipment in automated production, warehousing, and logistics. They achieve smooth and efficient transport of goods through the continuous rotation of motor-driven roller bodies. In these conveying systems, the powered roller bodies are mounted on supports of the conveyor frame via shafts at both ends.

[0003] During long-term operation, the power roller body requires regular maintenance or replacement due to motor failure, bearing wear, or cylinder damage. Currently, the common installation method involves drilling mounting holes or slots in the bracket and then using bolts, nuts, or snap rings to fix the roller shaft to the bracket. While this connection method is simple in structure and secure, its shortcomings become increasingly apparent when the roller needs to be disassembled. Maintenance personnel must use specialized tools such as wrenches and screwdrivers to loosen or tighten multiple fasteners located on both the inside and outside of the conveyor one by one. This process is not only cumbersome and time-consuming, but also particularly inconvenient when operating in confined spaces, directly leading to low equipment maintenance efficiency and extended production line downtime.

[0004] Furthermore, when the fasteners at both ends of the roller are loosened, the weighted power roller body is in an unstable, suspended or semi-suspended state. Maintenance personnel must support the roller with one hand and operate tools with the other during disassembly or installation. This not only increases the difficulty of operation but also greatly increases the risk of the roller falling due to slips, causing damage to the roller itself or surrounding equipment, and even threatening the personal safety of the operators. Existing support structures generally lack temporary support designs during disassembly and assembly transitions, making the entire maintenance process both inconvenient and unsafe. Utility Model Content

It aims to improve the problems of cumbersome operation steps, time-consuming and labor-intensive operation, and easy drop of rollers during disassembly and assembly, which may cause equipment damage or safety hazards.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a single-row power roller support that can be quickly disassembled and assembled, comprising: a support mechanism, a power roller body, a rotating shaft, a disassembly and assembly mechanism, and an auxiliary mechanism.

[0007] The disassembly and assembly mechanism includes a first operating handle, a first guide rod driven by the handle, and a movable ball bearing. The displacement of the first guide rod is used to control the engagement or disengagement of the ball bearing with the groove on the outer wall of the rotating shaft. The auxiliary mechanism includes a slidably mounted support plate, which supports the rotating shaft when in the extended position.

The disassembly / assembly mechanism is detachably locked to the rotating shaft by the ball bearings, and the support plate of the auxiliary mechanism is slidably mounted on the mounting plate.

[0009] Preferably, the disassembly and assembly mechanism further includes a pushing block disposed between the first operating handle and the first guide rod for transmitting driving force.

[0010] Preferably, the disassembly and assembly mechanism further includes a first spring and a first limiting pin; the first spring is sleeved on the first guide rod to provide a restoring force, and the first limiting pin passes through the mounting plate and slides in cooperation with the first guide rod.

[0011] Preferably, the first guide rod has an internal groove inside for receiving the ball when the first guide rod is displaced.

[0012] Preferably, the auxiliary mechanism further includes a second guide rod fixedly connected to the support plate, the second guide rod being used to drive the support plate to slide.

[0013] Preferably, the auxiliary mechanism further includes a limiting plate, which is fixed to the mounting plate, and the support plate is slidably mounted on the limiting plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 5 This utility model provides a single-row power roller support that can be quickly disassembled and assembled, which aims to solve the problems of inconvenient disassembly and assembly and low maintenance efficiency of power rollers in the prior art.

[0022] like Figures 1 to 5As shown, a quick-assembly and disassembly single-row power roller support includes a support mechanism 1, a power roller body 2, an assembly / disassembly mechanism 3, an auxiliary mechanism 4, and a rotating shaft 5. The support mechanism 1 includes a mounting plate 101 and a support frame 102. The mounting plate 101 is fixedly connected to the support frame 102, which provides basic support for the entire device. The power roller body 2 is fixedly connected to the outer periphery of the rotating shaft 5. A groove is provided on the outer wall of the rotating shaft 5. The assembly / disassembly mechanism 3 and the auxiliary mechanism 4 are both installed on the mounting plate 101. The assembly / disassembly mechanism 3 forms a detachable locking connection with one end of the rotating shaft 5. The auxiliary mechanism 4 is located below the rotating shaft 5.

[0023] Specifically, please refer to Figure 2 and Figure 3 The disassembly and assembly mechanism 3 includes a first operating handle 301, a pressing block 302, a first guide rod 303, a first spring 304, a first limiting pin 305, and a ball bearing 306. The first operating handle 301 is connected to the pressing block 302, and the end of the pressing block 302 abuts against one end of the first guide rod 303. The first guide rod 303 is axially movable and passes through the mounting plate 101. The first limiting pin 305 passes vertically through the mounting plate 101 and slides in a groove on the outer wall of the first guide rod 303 to limit the axial movement path of the first guide rod 303. The first spring 304 is sleeved... The first guide rod 303 is provided on the outer periphery, with its two ends abutting between the inner wall of the mounting plate 101 and the flange of the first guide rod 303, respectively, to provide a restoring elastic force for the first guide rod 303; the first guide rod 303 has an internal groove radially opened in its body for receiving a ball 306 at a specific position. The ball 306 is movably installed in the radial through hole of the mounting plate 101, and under the axial drive of the first guide rod 303, it extends radially to engage with the groove on the outer wall of the rotating shaft 5, or it retracts radially into the internal groove to disengage from the groove of the rotating shaft 5, thereby realizing the locking and unlocking of the rotating shaft 5; Please refer to Figure 4 and Figure 5The auxiliary mechanism 4 includes a support plate 401, a limiting plate 402, a second guide rod 403, a second limiting pin 404, and a second spring 405. The second guide rod 403 is fixedly connected to one end of the support plate 401 for manually driving the support plate 401 to slide. The support plate 401 is slidably disposed on the lower part of the mounting plate 101. The limiting plate 402 is fixed on the mounting plate 101 and serves as the lower guide rail for the sliding of the support plate 401. The second limiting pin 404 is fixed on the mounting plate 101 and is connected to the support plate 405. The sliding groove on the support plate 401 is used to limit the movement stroke and direction of the support plate 401; the second spring 405 is disposed inside the mounting plate 101, with one end abutting against the mounting plate 101 and the other end abutting against the inner side of the support plate 401, and is used to push the support plate 401 to be held in the extended position when there is no external force; the upper surface of the support plate 401 forms a support surface, and when the support plate 401 is in the extended position, its support surface contacts the bottom surface of the rotating shaft 5, providing reliable radial support for the rotating shaft 5.

[0024] In a preferred embodiment, the structure of the disassembly and assembly mechanism 3 is further defined. Specifically, the disassembly and assembly mechanism 3 further includes a pushing block 302, which is disposed between the first operating handle 301 and the first guide rod 303 to reliably transmit the pressing action of the first operating handle 301 to the first guide rod 303. To achieve automatic reset and precise guidance of the first guide rod 303, a first spring 304 is sleeved on the first guide rod 303, and a first limiting pin 305 passes through the mounting plate 101 and slides in cooperation with the elongated groove on the outer wall of the first guide rod 303. More specifically, an internal slot is radially formed in the body of the first guide rod 303. When the first guide rod 303 is pushed in, the internal slot moves to the position of the ball 306, thereby providing an inward retraction space for the ball 306. In another preferred embodiment, the structure of the auxiliary mechanism 4 is further defined. Specifically, the auxiliary mechanism 4 also includes a second guide rod 403 fixedly connected to the support plate 401 for conveniently driving the support plate 401 to slide. To provide stable sliding guidance, the auxiliary mechanism 4 also includes a limiting plate 402 fixed to the lower part of the mounting plate 101, and the support plate 401 is slidably mounted on the limiting plate 402. To realize the automatic extension and stroke limitation of the support plate 401, a second spring 405 is disposed inside the mounting plate 101 and abuts against the inner side of the support plate 401, and a second limiting pin 404 is fixed on the mounting plate 101 and forms a sliding fit with the groove on the support plate 401. In addition, to form a complete equipment frame, the support mechanism 1 also includes a support frame 102, and the mounting plate 101 is fixedly connected to the support frame 102 by welding or bolt fastening.

[0025] Working principle: When the equipment needs to be used, and when the power roller body 2 needs to be disassembled, first press the first operating handle 301. The pressing force is transmitted to the first guide rod 303 through the push block 302, causing the first guide rod 303 to slide along the guide axis of the first limit pin 305 against the elastic force of the first spring 304. As the first guide rod 303 slides, its internal groove moves to the position of the ball 306. The ball 306 retracts inward because it is no longer squeezed, disengaging from the engagement and locking state with the groove on the outer wall of the rotating shaft 5. At this time, the rotating shaft 5 together with the power roller body 2 can be pulled out from the mounting plate 101. During the pulling process, in order to facilitate the complete removal of the power roller body 2, manually pull the second guide rod 403, which drives the support plate 401 to overcome the second spring. The elastic force of 405 retracts along the limiting plate 402 until its supporting surface is completely detached from the support of the rotating shaft 5, thus providing complete space for disassembly. The installation process is the reverse of the disassembly process. First, the new power roller body 2 and the rotating shaft 5 are placed in the corresponding positions of the mounting plate 101. The second guide rod 403 is released, and the second spring 405 pushes the support plate 401 to automatically extend and support the rotating shaft 5. Then, the rotating shaft 5 is fully pushed into the mounting plate 101. When the groove on it is aligned with the ball 306, the first spring 304 pushes the first guide rod 303 to reset. The outer wall of the first guide rod 303 radially extrudes the ball 306 and locks it into the groove of the rotating shaft 5, achieving automatic locking. The entire installation process requires no tools and is extremely quick.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
