Description

Technical Field

[0001] The utility model relates to the technical field of transmission equipment, in particular to an adjustable transmission sprocket. Background Art

[0002] Sprocket drives are one of the drive systems used in material handling equipment. They consist of a drive sprocket, a transmission chain, and adjustment holes and tension bolts at the bottom of the drive unit. The main conveying system equipment typically operates as a single system, running continuously. Any failure in any of the main conveying system components will affect system operation, directly impacting material flow balance and, consequently, production. In the metallurgical industry, this can impact coke oven and blast furnace operations. Furthermore, if a drive sprocket tooth jump or break occurs during production, especially if the equipment is located in a confined space or at high altitude, similar failures can result in lengthy repair times and significant disruptions.

[0003] In existing equipment, when the transmission chain needs to be tensioned, it is generally achieved by adjusting the tensioning holes and tensioning bolts at the bottom of the driving device. When there is no adjustable spacing between the two sprockets or the equipment is located in a narrow space without adjustment holes and needs to be tensioned, one or two sections of the transmission chain can only be removed. This will cause the transmission chain to be too tight or the transmission chain cannot be installed. Therefore, an adjustable transmission sprocket is proposed. Utility Model Content

[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] Reference Figure 1-4 The utility model embodiment provides an adjustable transmission sprocket, which includes a first sprocket 1 and a second sprocket 2. The first sprocket 1 and the second sprocket 2 have different diameters and are both provided with a connecting hole in the middle. A transmission chain 3 is hinged between the first sprocket 1 and the second sprocket 2. An adjusting mechanism 4 is provided on the transmission chain 3. The adjusting mechanism 4 includes an upper adjusting plate 41 and a lower adjusting plate 42. The upper adjusting plate 41 and the lower adjusting plate 42 are both U-shaped. An opening 5 is provided between the upper adjusting plate 41 and the lower adjusting plate 42. A slide plate 7 is provided at the end, and several through holes 71 are provided on the slide plate 7. There are four through holes 71. A slide groove 8 is provided on the inner side of the upper end of the lower adjustment plate 42. A positioning hole 81 is provided in the slide groove 8. A latch 11 is slidably connected to the outer side of the upper end of the lower adjustment plate 42. The latch 11 is slidably connected to the through hole 71. The slide plate 7 is slidably connected to the slide groove 8 and is adapted to the slide groove 8. When it is necessary to adjust the tightness of the transmission chain 3, the appropriate through hole 71 and positioning hole 81 are selected and then fixed by the latch 11. The operation is simple and it is avoided to disassemble it.

[0023] The upper end of the upper adjusting plate 41 and the lower end of the lower adjusting plate 42 are both rotatably connected to the auxiliary wheels 6. The auxiliary wheels 6 at both ends of the upper adjusting plate 41 and the lower adjusting plate 42 are the same size and partially located in the opening 5. When the auxiliary wheels 6 are connected to the transmission chain 3, the transmission chain 3 is prevented from contacting the upper end of the upper adjusting plate 41 and the lower adjusting plate 42. The transmission chain 3 is located between the auxiliary wheels 6 on the upper and lower sides, and the transmission chains 3 on both sides are meshed and connected to the auxiliary wheels 6. A fixing plate 10 is provided at the bottom of the lower adjusting plate 42, and a limiting groove 9 is provided on the outer side of the lower end of the lower adjusting plate 42. The fixing plate 10 is U-shaped, and the opening is located on one side of the lower adjusting plate 42. One end of the opening of the fixing plate 10 is slidably connected to the limiting groove 9. A threaded hole is provided in the fixing plate 10. The fixing plate 10 is installed inside the equipment through the threaded hole. Under the action of the fixing plate 10, the adjustment mechanism 4 is prevented from being displaced when the first sprocket 1 and the second sprocket 2 drive the transmission chain 3 for transmission.

[0024] Working principle: When in use, first pass the lower adjusting plate 42 through the transmission chain 3, then install the fixing plate 10 inside the equipment through the threaded hole, and then pass the upper adjusting plate 41 through the upper transmission chain 3, so that the slide plate 7 slides and connects to the slide groove 8. At this time, the upper end of the upper adjusting plate 41 and the auxiliary wheel 6 in the lower adjusting plate 42 are both engaged with the transmission chain 3, and then the upper end of the upper adjusting plate 41 and the lower adjusting plate 42 are pressed inward to make the transmission chain 3 in a taut whole, and then the pin 11 cooperates with the through hole 71 and the positioning hole 81 to fix it. At the same time, under the action of the fixing plate 10, the adjustment mechanism 4 is prevented from being displaced when the first sprocket 1 and the second sprocket 2 drive the transmission chain 3 for transmission; when the transmission chain 3 needs to be adjusted in tightness, select the appropriate through hole 71 and positioning hole 81, and then fix it with the pin 11. The operation is simple and it can be avoided to disassemble it.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
