[0022] 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.
[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] A chain drive guiding mechanism for a hoist includes a fixed plate 1, a transmission assembly 2, two sets of sprockets 3 and two sets of chain bodies 4. The two sets of sprockets 3 are mounted on the top of the fixed plate 1 through the transmission assembly 2, and the two sets of chain bodies 4 are respectively connected to the surfaces of the two sets of sprockets 3. Two sets of guiding assemblies 5 are symmetrically arranged on the top of the fixed plate 1 for limiting and guiding the chain bodies 4 of the transmission.
[0025] With the setting of fixed plate 1, transmission component 2, two sets of sprockets 3, two sets of chain bodies 4 and guide component 5, the symmetrically set guide component 5 provides precise limiting and guiding functions during chain transmission, realizes bidirectional limiting and guiding of chain body 4, effectively prevents chain body 4 from running off-center, and ensures the stability of chain body 4 transmission.
[0026] Specifically, the guide assembly 5 includes a limiting frame 51, guide rollers 52, a first through groove 53, and a second through groove 54. The limiting frame 51 is installed on the top of the fixed plate 1, and multiple sets of guide rollers 52 are rotatably installed inside the limiting frame 51. A first through groove 53 for the chain body 4 to drive is opened on one side of the limiting frame 51, and a second through groove 54 for the chain body 4 to drive is symmetrically opened at the bottom of the limiting frame 51.
[0027] With the setting of guide component 5, the limiting frame 51 is fixedly installed on the fixed plate 1. The internal space of the frame is arranged with multiple sets of freely rotatable guide rollers 52, which transforms the sliding friction between the chain and the guide component 5 into rolling friction, thereby significantly reducing wear. The multiple sets of guide rollers 52 can respectively perform rolling limiting and guiding on both sides of the two sets of chain bodies 4, effectively constraining the lateral displacement of the chain and preventing deviation. The first through groove 53 and the second through groove 54 provide a smooth transmission channel for the chain body 4, which ensures the limiting effect without affecting the normal operation of the chain.
[0028] The bottom of the limiting frame 51 is provided with two sets of mounting holes 6, and the first bolts 7 are installed in the two sets of mounting holes 6 respectively. The top of the fixing plate 1 is provided with a first threaded hole 8 for the first bolts 7 to be threaded.
[0029] With the installation holes 6, the first bolt 7 and the first threaded hole 8, the first bolt 7 is installed in the two sets of installation holes 6 at the bottom of the limit frame 51 and screwed into the corresponding first threaded hole 8 at the top of the fixing plate 1. This connection method makes installation and disassembly convenient. When the equipment malfunctions or needs maintenance, the limit frame 51 can be quickly disassembled and repaired, improving equipment maintenance efficiency.
[0030] In a further preferred embodiment, mounting plates 9 are fixedly installed on both sides of the limiting frame 51, and second bolts 10 are installed inside the two sets of mounting plates 9 respectively. The top of the fixing plate 1 is provided with a second threaded hole 11 for threaded installation of the second bolts 10.
[0031] By setting the mounting plate 9, the second bolt 10, and the second threaded hole 11, the second bolt 10 is inserted into the mounting plate 9 and screwed into the second threaded hole 11, which further enhances the connection strength between the limit frame 51 and the fixing plate 1, so that the limit frame 51 remains stable during the operation of the equipment, effectively resisting the vibration and external force generated by the transmission of the chain body 4, thereby ensuring that the guide assembly 5 plays a stable role in the long term.
[0032] Specifically, a groove 12 is provided on the side of the limiting frame 51 away from the chain body 4.
[0033] By setting the groove 12, the groove 12 can ensure the strength of the frame structure while also facilitating the installation and removal of the first bolt 7.
[0034] The fixed plate 1 has two sets of slots 13 on both sides for the chain body 4 to drive, and the multiple sets of slots 13 are arranged in a rectangular array.
[0035] With the slots 13 set, the slots 13 arranged in a rectangular array on both sides of the fixing plate 1 provide a transmission channel for the chain body 4, avoiding unnecessary interference and collision with the fixing plate 1. At the same time, when the chain body 4 fails due to long-term use or unexpected circumstances, maintenance personnel can directly remove the faulty chain from the slots 13, significantly shortening the troubleshooting and repair time, and making equipment maintenance and repair work easier and more efficient.
[0036] Specifically, the transmission assembly 2 includes a support plate 21, a motor 22, and a rotating rod 23; the motor 22 is fixedly installed on one side of the support plate 21, and the support plate 21 is fixedly installed on the top of the fixed plate 1. The output end of the motor 22 is fixedly connected to one end of the rotating rod 23 through a coupling, and the rotating rod 23 is rotatably installed inside the support plate 21. Both sets of sprockets 3 are rotatably installed on the outside of the rotating rod 23.
[0037] With the transmission component 2 in place, the motor 22 can be a Panasonic MINAS-A6 series servo motor. The motor 22 is fixedly installed on one side of the support plate 21, and the support plate 21 is firmly installed on the top of the fixed plate 1, providing reliable support for the motor 22. The motor 22 is connected to the rotating rod 23 through a coupling, which efficiently transmits power to the rotating rod 23. The rotating rod 23 rotates flexibly within the support plate 21, and two sets of sprockets 3 are installed on its outer side to achieve synchronous and stable rotation, providing continuous and stable power output for the chain body 4 transmission.
[0038] The top of the fixed plate 1 is fixedly mounted with the connecting plate 14, and the end of the rotating rod 23 away from the motor 22 is rotatably mounted on one side of the connecting plate 14.
[0039] By setting the connecting plate 14, the connecting plate 14 provides support for the end of the rotating rod 23 away from the motor 22, ensuring that the rotating rod 23 maintains coaxiality and stability during rotation, avoiding the rotating rod 23 from tilting due to insufficient support at one end, ensuring the accuracy of the sprocket 3 and chain drive, and further improving the operating accuracy and reliability of the entire transmission system.
[0040] Working principle: When this utility model is in use, the motor 22 drives the rotating rod 23 to rotate through the coupling, which drives the two sets of sprockets 3 on the rotating rod 23 to rotate synchronously, thereby driving the two sets of chain bodies 4 to transmit power. During the transmission process, the symmetrically arranged guide components 5 play a key role: the multiple sets of guide rollers 52 inside them respectively roll and limit and guide the two sides of the two sets of chain bodies 4, effectively constraining the lateral displacement of the chain and preventing deviation. The first through groove 53 and the second through groove 54 provide a smooth transmission channel for the chain body 4, which not only ensures the limiting effect, but also does not affect the normal operation of the chain. This rolling contact guiding method greatly reduces friction loss, making the entire transmission structure run more smoothly and efficiently, thereby significantly improving the reliability of the chain body 4 transmission.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
