Description

Technical Field

[0001] The utility model belongs to the technical field of equipment connection, and mainly relates to a device for quickly removing a head trolley of a sintering machine. Background Art

[0002] Non-rigid oil-free slideway seals are a newly emerging type of sintering machine slideway seal. They consist of an upper slideway, welded from a wear-resistant alloy, and a lower slideway, a non-metallic sealing member. The upper slideway is a special-shaped structure, while the lower slideway sealing strip is a wear-resistant, high-temperature-resistant (480°C) non-metallic polymer composite material, offering excellent sealing, compensating, and practical performance. The lower slideway sealing strip ensures a tight seal at the connection between the trolley and the bellows, directly impacting sintering strength and product quality.

[0003] The sealing tape of the downhill slide is a consumable part and has a certain impact on its service life depending on the working conditions. It generally needs to be replaced every 6-8 months. Although the replacement of the sealing tape is more convenient and time-saving than that of the traditional steel slide, after the sintering machine is shut down, the temperature under the igniter is affected by the insulation effect of the igniter insulation layer, and the internal temperature of the sintering machine is very high. Replacing the sealing tape and pushing the trolley often requires a lot of time, energy, manpower and material resources. The high internal temperature has a great impact on the operators and even poses a risk of burns. Therefore, it is necessary to design a device to quickly remove the trolley under the head igniter, so as to avoid people pushing the trolley, so as to solve the problem of quickly completing maintenance under high temperatures.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0033] The following describes various non-limiting embodiments of the present invention. The numbers of any elements in the accompanying drawings are for illustrative purposes only and are not intended to be limiting. Any nomenclature is provided for distinction only and does not have any limiting meaning. It should be noted that the embodiments and features of the embodiments of the present invention may be combined with one another unless there is a conflict.

[0034] like Figure 1 As shown, a device for quickly removing the head trolley of a sintering machine is provided. The device is a connecting mechanism 24 that can lock and unlock two adjacent trolleys 23. In order to strengthen the connection between two adjacent trolleys 23, multiple connecting mechanisms 24 can be arranged according to actual conditions.

[0035] like Figure 1-Figure 3 As shown, the connecting mechanism 24 includes a first connector 1 and a second connector 2, each for being fixedly mounted on two adjacent vehicles 23. That is, on adjacent sides of the two adjacent vehicles 23, the first connector 1 is fixedly mounted on one vehicle 23, and the second connector 2 is fixedly mounted on the other vehicle 23. Regarding the definition of direction in this embodiment, the second connector 2 is located in front of the first connector 1.

[0036] Among them, such as Figure 4-Figure 9As shown, the first connector 1 includes a mounting base 22 and a fixing block 16 that are fixedly connected together. The mounting base 22 is used to be fixedly installed on the corresponding vehicle 23, and the fixing block 16 is used to extend outward. The front end of the fixing block 16 is fixedly assembled with a front connecting member 7. At the same time, the fixing block 16 is slidably assembled with a rear connecting member 8 located between the front connecting member 7 and the mounting base 22. The front connecting member 7 has a first inclined surface 17 and a first stop surface 18. The first inclined surface 17 is located in front of the first stop surface 18 and is inclined upward from front to back. The first stop surface 18 is a vertical plane. The rear connecting member 8 has a second inclined surface 20 and a second stop surface 19. The second inclined surface 20 is located behind the second stop surface 19 and is inclined downward from front to back. The second stop surface 19 is a vertical plane. The first stop surface 18 is adjacent to and parallel to the second stop surface 19. A stop block 10 located between the rear connecting member 8 and the mounting seat 22 is fixed on the fixing block 16 , and a removable limiting member 4 is provided on the stop block 10 .

[0037] Among them, such as Figure 4-Figure 6 As shown, a movable seat 3 is slidably mounted on the second connector 2. The movable seat 3 has a cavity 9 therein. The movable seat 3 is provided with a spring pin 5 extending into the cavity 9. The spring pin 5 is a common structure and will not be described in detail in this embodiment. The portion of the spring pin 5 extending into the cavity 9 has a third inclined surface 14 and a third stop surface 15. The third inclined surface 14 is located on the rear side of the third stop surface 15. The third inclined surface 14 is inclined upward from front to back, and the third stop surface 15 is a vertical plane. The spring pin 5 can be arranged on the upper and lower sides of the movable seat 3. This embodiment takes the spring pin 5 located on the upper side of the movable seat 3 as an example to introduce the third inclined surface 14 and the third stop surface 15 on the spring pin 5. The spring pin 5 on the lower side is symmetrical with the spring pin 5 on the upper side.

[0038] When the movable seat 3 moves toward the mounting seat 22, the first inclined surface 17 and the spring pin 5 will be wedge-fitted, that is, the spring pin 5 can move upward along the first inclined surface 17. After the wedge-fitting is completed, the spring pin 5 will pass over the front connecting member 7 and reach the rear side of the front connecting member 7. At this time, the first stop surface 18 and the third stop surface 15 are blocked and fitted. Through the restriction between the spring pin 5 and the front connecting member 7, the movable seat 3 cannot move in the direction of the second connecting head 2, and at this time, the limit member 4 simultaneously contacts the movable seat 3 and the mounting seat 22. At this time, the two adjacent vehicles 23 are in a locked state, that is, the connection and fixation between the two adjacent vehicles 23 is achieved.

[0039] When it is necessary to separate two adjacent vehicles 23, the limit piece 4 needs to be removed. At this time, there is no restriction of the limit piece 4, and the mobile seat 3 can move toward the direction of the mounting seat 22. During the movement of the mobile seat 3, the spring pin 5 presses the rear connecting piece 8. At this time, the spring pin 5 has a weight for the rear connecting piece 8 in the front and rear directions, so the rear connecting piece 8 will slide toward the direction of the mounting seat 22. After the rear connecting piece 8 slides into place, the rear connecting piece 8 and the stop block 10 will be blocked, that is, the stop block 10 prevents the rear connecting piece 8 from continuing to move. Subsequently, the rear connecting piece 8 is wedge-shaped with the third inclined surface 14, and the spring pin 5 moves along the third inclined surface 14. Lift, after the wedge-shaped fit is completed, the spring pin 5 will pass over the rear connecting piece 8, then the spring pin 5 will be wedge-fitted with the second inclined surface 20, and the movable seat 3 will drive the spring pin 5 to move toward the direction of the second connecting head 2, then the spring pin 5 will press the rear connecting piece 8, so that the rear connecting piece 8 will move on the fixed block 16 toward the direction of the front connecting piece 7 until the first stop surface 18 and the second stop surface 19 are in contact with each other, then the spring pin 5 will slide on the second inclined surface 20 and the first inclined surface 17 in turn, and pass over the rear connecting piece 8 and the front connecting piece 7 in turn, at this time the two adjacent vehicles 23 are in an unlocked state, that is, the separation between the two adjacent vehicles 23 is achieved.

[0040] When unlocking is required, it is only necessary to remove the limit piece 4 and then move the movable seat 3 toward the mounting seat 22. When the spring pin 5 passes over the rear connecting piece 8, the movable seat 3 is immediately moved in the direction away from the mounting seat 22, so that the two adjacent vehicles 23 are in the unlocked state, which is convenient and quick.

[0041] Specifically, the second connecting head 2 extends into the cavity 9 of the movable seat 3, the second connecting head 2 has a fourth stop surface, the cavity 9 of the movable seat 3 has a fifth stop surface, the fifth stop surface is located in front of the fourth stop surface, and the fourth stop surface cooperates with the fifth stop surface to prevent the movable seat 3 from sliding off the second connecting head 2.

[0042] like Figure 6 、 Figure 10 As shown, the stopper 4 has a pressing portion 12 for contacting the movable seat 3. There are two pressing portions 12, one for pressing the upper side and the other for pressing the lower side of the movable seat 3. The pressing portion 12 for pressing the lower side of the movable seat 3 has a fourth inclined surface 13. The fourth inclined surface 13 is used to wedge-fit with the rear connecting member 8 when the stopper 4 is removed, thereby facilitating smooth removal of the stopper 4.

[0043] like Figure 4 、 Figure 11 As shown, the upper side of the mounting seat 22 has a groove 21, and the limiting member 4 has a protrusion 11 that fits in the groove 21. The fit between the protrusion 11 and the groove 21 realizes the installation positioning between the limiting member 4 and the mounting seat 22, making the installation position of the limiting member 4 more accurate.

[0044] like Figure 2 、 Figure 3 As shown, the limiting member 4 is provided with a handle 6. When unlocking, the staff can directly remove the limiting member 4 through the handle 6, so that the two adjacent vehicles 23 can be more quickly changed to the unlocked state.

[0045] The limiting member 4 in this embodiment is U-shaped, and is buckled upside down on the stopping block 10 .
