Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Embodiment 1:

[0030] See also Figure 1 , 2 , 4, 5, the utility model provides a technical solution: To achieve the above-mentioned purpose, the utility model provides the following technical solution: A device for quenching a crawler plate body in a trolley furnace, comprising: a trolley furnace body 1 with two ends connected; sealing door assemblies 9 are installed at both ends of the trolley furnace body 1; a heating assembly 2 is installed on the inner wall of the trolley furnace body 1; a moving platform 3 is installed at the bottom of the trolley furnace body 1, a guide rail 4 is installed on the top of the moving platform 3, two groups of sliding blocks 5 are installed on the top of the guide rail 4, and a placement seat 7 is fixed on the top of the two groups of sliding blocks 5; a placement piece is arranged on the top of the two placement seats 7; the placement piece is composed of a plurality of pillars 8, and the plurality of pillars 8 are equidistantly distributed on the top of the placement seat 7.

[0031] Specifically, since both ends of the trolley furnace body 1 are through-type, the two placement seats 7 (track plates) can be pushed into the interior at the same time with the cooperation of the two sets of sliding blocks 5, thereby increasing the speed of placing the track plates into the trolley furnace body 1, thereby increasing the quenching efficiency of the track plates.

[0032] Furthermore, since the placement piece is composed of a plurality of pillars 8, the contact area between the track shoe body and the placement piece is reduced, thereby improving the overall heating efficiency of the track shoe body and the overall heating uniformity of the track shoe body, thereby improving the quenching effect of the track shoe body.

[0033] Embodiment 2:

[0034] See also Figure 1-5 The utility model provides a technical solution: a device for quenching a crawler plate body in a trolley furnace, limit blocks 15 are fixed at both ends of the trolley furnace body 1, the top of the limit block 15 abuts against the bottom of the sealing door assembly 9, a scraper strip 11 is fixed to the bottom of the placement seat 7, and the bottom of the scraper strip 11 is 1 cm away from the top of the moving platform 3, a support strip 10 is fixed to the outer wall of the pillar 8, a threaded hole 12 is opened at the top of the placement seat 7, a threaded rod 13 is connected to the inner thread of the threaded hole 12, a rotating shaft 14 is fixed to the top of the threaded rod 13, and a fixing plate 6 is fixed to the bottom of the threaded rod 13.

[0035] Specifically, by fixing the limiting blocks 15 at both ends of the trolley furnace body 1, the top of the limiting blocks 15 abuts against the bottom of the sealing door assembly 9. On the one hand, the limiting blocks 15 can improve the sealing performance of the connection between the sealing door assembly 9 and the trolley furnace body 1, avoid heat loss, and thus improve the quenching efficiency of the track plate body as a whole. On the other hand, the limiting blocks 15 can support and limit the sealing door assembly 9 to avoid the sealing door assembly 9 from sinking due to gravity, thereby improving the working efficiency of the sealing door assembly 9 and the sealing performance of the connection between the sealing door assembly 9 and the trolley furnace body 1.

[0036] By fixing a scraper bar 11 at the bottom of the placement seat 7, when the placement seat 7 and the crawler plate body are pushed out as a whole, the scraper bar 11 will move with the placement seat 7 and the crawler plate body as a whole, and the scraper bar 11 will clean the debris on the top of the mobile platform 3 when it moves, thereby improving the cleanliness of the top of the mobile platform 3 and avoiding manual cleaning, which is highly practical.

[0037] By fixing the support bar 10 on the outer wall of the pillar 8, the support bar 10 can improve the structural strength of the pillar 8, prevent the pillar 8 from being deformed or broken due to excessive pressure, and improve the working efficiency and service life of the pillar 8;

[0038] By rotating the rotating shaft 14, the rotating shaft 14 will drive the threaded rod 13 to move in the threaded hole 12. After the fixed plate 6 at the bottom of the threaded rod 13 abuts against the movable platform 3, the placement seat 7 can be fixed to prevent the placement seat 7 from shaking, thereby improving the overall stability of the crawler shoe body, and indirectly improving the overall quenching efficiency of the crawler shoe body. The threaded rod 13 and the fixed plate 6 can also provide auxiliary support for the placement seat 7 to prevent the placement seat 7 from being deformed or broken due to excessive pressure, thereby improving the working efficiency and service life of the placement seat 7.

[0039] Working principle:

[0040] First, since the two ends of the trolley furnace body 1 are through-type, the two placement seats 7 (track plates) can be pushed into the trolley furnace body 1 at the same time with the cooperation of the two sets of sliding blocks 5, which improves the speed of placing the track plates into the trolley furnace body 1, thereby improving the quenching efficiency of the track plates;

[0041] Furthermore, since the placement piece is composed of a plurality of pillars 8, the contact area between the track shoe body and the placement piece is reduced, the heating efficiency of the track shoe body as a whole is improved, and the heating uniformity of the track shoe body as a whole is also improved, thereby improving the quenching effect of the track shoe body;

[0042] Secondly, by fixing the limiting blocks 15 at both ends of the trolley furnace body 1, the top of the limiting blocks 15 abuts against the bottom of the sealing door assembly 9. On the one hand, the limiting blocks 15 can improve the sealing performance of the connection between the sealing door assembly 9 and the trolley furnace body 1, thereby preventing heat loss and improving the quenching efficiency of the track plate body as a whole. On the other hand, the limiting blocks 15 can support and limit the sealing door assembly 9 to prevent the sealing door assembly 9 from sinking due to gravity, thereby improving the working efficiency of the sealing door assembly 9 and improving the sealing performance of the connection between the sealing door assembly 9 and the trolley furnace body 1.

[0043] By fixing a scraper bar 11 at the bottom of the placement seat 7, when the placement seat 7 and the crawler plate body are pushed out as a whole, the scraper bar 11 will move with the placement seat 7 and the crawler plate body as a whole, and the scraper bar 11 will clean the debris on the top of the mobile platform 3 when it moves, thereby improving the cleanliness of the top of the mobile platform 3 and avoiding manual cleaning, which is highly practical. Since the bottom of the scraper bar 11 is 1 cm away from the top of the mobile platform 3, the scraper bar 11 will not contact the mobile platform 3 when it moves, thereby avoiding friction damage to the scraper bar 11 and the mobile platform 3, and ensuring that the scraper bar 11 can move smoothly, thereby improving the efficiency of the scraper bar 11 in cleaning the debris;

[0044] By fixing the support bar 10 on the outer wall of the pillar 8, the support bar 10 can improve the structural strength of the pillar 8, prevent the pillar 8 from being deformed or broken due to excessive pressure, and improve the working efficiency and service life of the pillar 8;

[0045] By rotating the rotating shaft 14, the rotating shaft 14 will drive the threaded rod 13 to move in the threaded hole 12. After the fixed plate 6 at the bottom of the threaded rod 13 abuts against the movable platform 3, the placement seat 7 can be fixed to prevent the placement seat 7 from shaking, thereby improving the overall stability of the crawler shoe body, and indirectly improving the overall quenching efficiency of the crawler shoe body. The threaded rod 13 and the fixed plate 6 can also provide auxiliary support for the placement seat 7 to prevent the placement seat 7 from being deformed or broken due to excessive pressure, thereby improving the working efficiency and service life of the placement seat 7.
