Description

Technical Field

[0001] The utility model relates to the technical field of chain conveyors, in particular to an assembly and positioning device for a sprocket support on a chain conveyor. Background Technique

[0002] A chain conveyor is a transportation device that uses a chain as a transmission device, and has the characteristics of fast transportation speed, good wear resistance, high reliability, etc. It generally consists of components such as a chain, a tray, a sprocket, a positioning bracket, and a frame, and then components such as slats, metal mesh belts, and roller paths are added to the chain to carry and convey materials, and it is widely used.

[0003] Most of the existing positioning brackets for installing sprockets on chain conveyors are directly welded to the frame by means of group welding. During the welding process, since the positions of the two positioning brackets on the frame are not easy to fix, it is easy to cause a height difference between the positioning holes reserved on the two positioning brackets, and the welded positioning brackets cannot be adjusted. At this time, the installed sprockets will also have a height difference, which easily leads to problems that subsequent parts cannot be normally installed and used.

[0004] Therefore, we have proposed an assembly and positioning device for a sprocket support on a chain conveyor. Content of the Utility Model

Detailed implementation mode

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 4 , the present invention provides a group positioning device for a sprocket bracket on a chain conveyor, including a chassis 1. A first threaded rod 17 is rotatably connected inside the chassis 1. Two sliding seats 8 are sleeved on the first threaded rod 17. Brackets 2 are fixedly installed at the tops of the two sliding seats 8. A second threaded rod 10 is rotatably connected inside each of the two brackets 2. Sliders 11 are sleeved on the two second threaded rods 10. First positioning brackets 3 are fixedly installed on one side of the two sliders 11 close to each other. Second positioning brackets 4 are arranged on one side of the two first positioning brackets 3 close to each other. A sprocket 5 is arranged between each first positioning bracket 3 and the second positioning bracket 4. Positioning holes 6 are arranged on each first positioning bracket 3 and the second positioning bracket 4. The two ends of each sprocket 5 are respectively rotatably connected in the corresponding positioning holes 6. A plurality of screw holes 13 are arranged at the rear of the positioning holes 6 on each first positioning bracket 3 and the second positioning bracket 4. Fixing bolts 14 are threadedly connected in the plurality of screw holes 13.

[0022] On one side where the two first positioning brackets 3 are close to each other, positioning sleeves 16 are fixedly installed. On one side where the two second positioning brackets 4 are far from each other, positioning members 15 are fixedly installed. The two positioning members 15 are inserted into the corresponding positioning sleeves 16 on the side far from each other. Through this design, it is convenient to position the second positioning bracket 4. The two positioning sleeves 16 are both arranged on the first positioning bracket 3 behind the screw holes 13. Through this design, it is beneficial to the use of this equipment. On the left side of the first threaded rod 17, a turning disk 9 is fixedly installed. Through the turning disk 9, it is convenient to drive the first threaded rod 17 to rotate. On the top ends of the two second threaded rods 10, turntables 12 are fixedly installed. Through the turntables 12, it is convenient to drive the second threaded rods 10 to rotate. The first threaded rod 17 is provided with two sections of opposite threads, and the two sliding seats 8 are respectively sleeved on the two sections of threads. Through this design, it is beneficial to the use of this equipment. On both sides of the chassis 1, mounting plates 7 are fixedly installed. A plurality of mounting holes are reserved on the two mounting plates 7. Through the plurality of mounting holes, it is convenient to fix this equipment with external bolts.

[0023] Working principle: When in use, first insert one end of the sprocket 5 into the positioning hole 6 on the first positioning bracket 3, then insert the positioning member 15 on the second positioning bracket 4 into the positioning sleeve 16, so that a plurality of screw holes 14 are aligned. Then rotate the two fixing bolts 13, so that one end of the two fixing bolts 13 close to the second positioning bracket 4 extends into the screw holes 14. At the same time, the other end of the sprocket 5 is inserted into the positioning hole 6 on the second positioning bracket 4, and the installation of the sprocket 5 can be completed. According to the use requirements, the turntable 12 can be used to drive the second threaded rod 10 to rotate. Since the slider 11 is provided with corresponding threads on the second threaded rod 10, the slider 11 can drive the first positioning bracket 3 and the second positioning bracket 4 to move up and down, so as to adjust the height of the sprockets 5 on the two brackets 2. According to the use requirements, the turning disk 9 can be used to drive the first threaded rod 17 to rotate. At this time, the two sliding seats 8 drive the two brackets 2 to slide towards the side close to each other, and the distance between the two sprockets 5 can be adjusted. The assembly and positioning device of the sprocket bracket on this chain conveyor is convenient to use. Through the above components, the height of a plurality of positioning holes 6 can be adjusted and aligned, thus avoiding the problem that the reserved hole positions of the positioning brackets welded by the traditional resistance welding method are prone to deviation, resulting in the subsequent parts being unable to be normally installed and used. At the same time, the distance between the two vertical brackets 2 can be adjusted according to the use requirements, which is convenient to adapt to the installation of conveying parts such as slats, wire mesh belts, and roller paths of different lengths, thereby further improving the applicability of this equipment.
