Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mining technology, specifically to a modular toothed rail seat with a detachable integrally cast central groove. Background Technology
[0002] Due to material and process issues, welded and cast-welded chutes on the market generally need to be brought to the surface for maintenance after one working face has been used underground. When there is a large amount of coal reserves in the working face, it may be necessary to bring the chutes to the surface for replacement before the working face is fully mined. The toothed rail seat is a key stress-bearing part of the chutes and is one of the most easily damaged parts of the chutes. If it is damaged, the entire chute needs to be replaced.
[0003] Based on the above description, the existing technology still has the following shortcomings:
[0004] If the toothed rail seat is damaged, it will cause the entire fully mechanized mining face to stop production. Due to the underground conditions, it is time-consuming and labor-intensive to replace a section of the middle slot. If the toothed rail seat of a section of the middle slot is damaged, it may take workers one or two shifts to replace it, which seriously delays production efficiency.
[0005] The rack seat is where the rack rail is housed and is a crucial connection point between the scraper conveyor and the coal mining machine. When these three machines are used together, the rack seat, rack rail, and traveling mechanism of the scraper conveyor must all be of the same model. Because the conditions at each working face underground are different, sometimes the trough may meet the requirements, but if the rack seat, rack rail, and traveling mechanism are different from the coal mining machine's model, a complete scraper conveyor system must be purchased to be compatible with the existing coal mining machine, significantly increasing production costs.
[0006] Currently, center channels on the market are usually welded or cast-welded, using ordinary cast steel or cast iron as materials and ordinary heat treatment processes. The resulting center channels have low weld strength, are prone to weld breakage, have low strength, low wear resistance, and short service life. Therefore, a modular toothed rail seat with detachable integral casting center channel is proposed. Utility Model Content

[0028] Example
[0029] Please see Figure 1-5 This utility model provides a technical solution: a modular toothed rail seat with detachable integral casting central groove, including integral casting groove body 1, integral casting toothed rail seat 6 installed on integral casting groove body 1, and connecting component provided on integral casting groove body 1; positioning component 8, the positioning component 8 is installed on integral casting toothed rail seat 6, and the positioning component 8 is used for the installation and positioning of integral casting toothed rail seat 6.
[0030] By setting up connecting components, the integral cast toothed rail seat 6 can be quickly replaced, saving time and effort. Moreover, different models of integral cast toothed rail seats 6 can be selected according to actual conditions to meet the needs of different models of coal mining machines and different working conditions, making it more flexible and reducing costs and improving work efficiency for the mine. At the same time, the integral cast toothed rail seat 6 is cast in one piece, with high strength, strong wear resistance and longer service life.
[0031] The connecting assembly includes a mounting base 2, which is mounted on the integral casting tank 1. The top of the mounting base 2 has a positioning hole 3, and a first mounting hole 4 is located behind the positioning hole 3. The mounting base 2 is an L-shaped plate, and a second mounting hole 5 is located on its rear side. Hexagonal head bolts 7 are connected to the top and rear of the integral casting gear seat 6. A connecting hole 9 is located on the front side of the hexagonal head bolts 7 at the top of the integral casting gear seat 6. The two hexagonal head bolts 7 are respectively connected to the interiors of the first mounting hole 4 and the second mounting hole 5. By aligning the positioning pin 81 with the positioning hole 3, the integral casting gear seat 6 is placed on the mounting base 2, allowing the positioning pin 81 to be inserted into the positioning hole 3 for installation. Then, the two hexagonal head bolts 7 are inserted through the integral casting gear seat 6 into the interiors of the first mounting hole 4 and the second mounting hole 5, respectively. Finally, the two hexagonal head bolts 7 are fixed using spring washers and nuts, thus completing the installation of the integral casting tank 1 and the integral casting gear seat 6.
[0032] To ensure the locating pin 81 can be reused multiple times and to facilitate the installation of the integrally cast gear seat 6, the locating assembly 8 includes a locating pin 81 and a connecting bolt 83. The locating pin 81 is inserted into the connecting hole 9. The top of the locating pin 81 is provided with an internal threaded hole 82. The connecting bolt 83 is threaded into the internal threaded hole 82. The bottom of the internal threaded hole 82 is provided with a connecting groove 85. Both ends of the connecting groove 85 are provided with balls 86. The bottom end of the connecting bolt 83 is provided with a cone 84, which abuts against the outer side of the balls 86. The inner side of the connecting hole 9 is provided with... The annular groove 87 is in which the ball bearing 86 is located. The positioning pin 81 matches the positioning hole 3 and is inserted into the positioning hole 3. Before the integral casting tank 1 and the integral casting gear seat 6 are installed, the positioning pin 81 needs to be inserted into the connecting hole 9 first, and then the connecting bolt 83 is screwed into the internal thread hole 82. This causes the cone 84 at the bottom of the internal thread hole 82 to push the ball bearing 86 to move inside the connecting groove 85, so that the ball bearing 86 moves into the annular groove 87. This completes the fixing of the positioning pin 81, so as to facilitate the installation and positioning of the integral casting gear seat 6.
[0033] The working principle or structural principle is as follows: When installing the integrally cast gear seat 6 on the integrally cast groove 1, the locating pin 81 needs to be inserted into the connecting hole 9 first, and then the connecting bolt 83 is screwed into the internal threaded hole 82. This causes the cone 84 at the bottom of the internal threaded hole 82 to push the ball 86 to move inside the connecting groove 85, so that the ball 86 moves into the annular groove 87, thus completing the fixing of the locating pin 81. This is simple and quick, and can ensure that the locating pin 81 can be reused multiple times. During installation, the integrally cast gear seat 6 is placed on the mounting base 2 by aligning the locating pin 81 with the locating hole 3, so that the locating pin 81 is inserted into the locating hole 3, which facilitates the installation of the integrally cast gear seat 6. At this time, the two hexagonal... The head bolts 7 are inserted through the integral cast gear seat 6 into the first mounting hole 4 and the second mounting hole 5, respectively. Then, the two hexagonal head bolts 7 are fixed by spring washers and nuts, thus completing the installation of the integral cast groove 1 and the integral cast gear seat 6. The separation of the integral cast groove 1 and the integral cast gear seat 6 allows for quick replacement of the integral cast gear seat 6 when it is damaged, saving time and effort. Moreover, different models of integral cast gear seats 6 can be selected according to actual conditions to meet the needs of different models of coal mining machines and different working conditions, which is more flexible and can reduce costs and improve work efficiency for the mine. At the same time, the integral cast gear seat 6 is cast in one piece, with high strength, strong wear resistance and longer service life.
