[0029] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] Embodiment 1

[0031] As attached Figure 1 To Attachment Figure 4 As shown, the present invention provides a device for adjusting the distance between clamping hammers of a coke oven tamping machine, comprising a tamping hammer 1, wherein the tamping hammer 1 is used to tamp the coking coal into coal cakes, bearing seats 2 are arranged on both sides of the tamping hammer 1, wherein the bearing seats 2 provide installation space for internal parts, and elastic cams 3 are arranged in the bearing seats 2, wherein two elastic cams 3 are arranged and are respectively located on both sides of the tamping hammer 1, and the two elastic cams 3 are used to squeeze the two sides of the tamping hammer 1, thereby clamping the tamping hammer 1, and the elastic cam 3 is connected to a moving component 4, wherein the moving component 4 drives the elastic cam 3 to move toward the tamping hammer 1, and the moving component 4 is connected to a fitting component 5, wherein the fitting component 5 provides a thrust so that the moving component 4 drives the elastic cam 3 to fit with the tamping hammer 1, and the fitting component 5 is connected to an adjustment component 6, wherein the adjustment component 6 is used to adjust the preload force of the fitting spring 502 in the fitting component 5 to ensure that the elastic cam 3 and the tamping hammer 1 are closely fitted;

[0032] As attached Figure 4 As shown, the fitting component 5 includes a fixed plate 501, wherein the position of the fixed plate 501 is adjusted and fixed, and the fixed plate 501 is connected to a fitting spring 502, wherein the fitting spring 502 is in a force storage state, and when the elastic cam 3 changes size due to wear, the fitting spring 502 will synchronously push the fitting plate 503 and the moving component 4 to move in the direction of the tamping hammer 1, and automatically compensate for the distance change caused by wear, and the fitting spring 502 is connected to a fitting plate 503, wherein the fitting plate 503 is used to transmit the thrust of the fitting spring 502, so that the thrust is stably transmitted to the moving component 4.

[0033] As can be seen from the above, with the passage of time, the elastic cam 3 gradually wears and its size changes due to wear. Since the preload of the fitting spring 502 in the fitting component 5 has been adjusted by the adjustment component 6 before use, the fitting spring 502 will push the fitting plate 503 and the moving component 4 to move toward the tamping hammer 1, automatically compensating for the spacing change caused by wear, ensuring that the elastic cam 3 and the tamping hammer 1 maintain a tight fit, thereby eliminating the need for frequent manual inspection or adjustment, reducing manual intervention and improving work efficiency.

[0034] Embodiment 2

[0035] As attached Figure 3 To Attachment Figure 4 As shown, this embodiment is basically the same as the previous embodiment, with the difference that the moving component 4 includes a sliding groove 401 and an auxiliary groove 402 opened inside the bearing seat 2, wherein the sliding groove 401 is used to assist the directional movement of the sliding block 403, and the auxiliary groove 402 is used to open a channel for the elastic cam 3 to move, and the sliding groove 401 is slidably connected to the sliding block 403, and the sliding block 403 is connected to the support bearing 404, and when the sliding block 403 moves, it will drive the support bearing 404 to move synchronously.

[0036] As attached Figure 3 As shown, specifically, the support bearing 404 is connected to the elastic cam 3. When the sliding block 403 moves, the support bearing 404 drives the elastic cam 3 to move toward the tamping hammer 1. The elastic cam 3 is located in the auxiliary groove 402. The bonding plate 503 is fixedly connected to the sliding block 403. The bonding plate 503 stably transmits the thrust of the bonding spring 502 to the sliding block 403.

[0037] As attached Figure 4 As shown, further, the adjustment component 6 includes a push-pull rod 601 fixedly connected to the bonding plate 503, wherein when the bonding plate 503 pushes the sliding block 403 to move toward the tamping hammer 1, the push-pull rod 601 will also move synchronously, and the push-pull rod 601 is slidably connected with a threaded sleeve 602, wherein the push-pull rod 601 passes through the interior of the threaded sleeve 602, and the threaded sleeve 602 assists the push-pull rod 601 and the bonding plate 503 to slide smoothly, and the threaded sleeve 602 is threadedly connected to the fixed plate 501, and the fixed plate 501 is rotated on the threaded sleeve 602. The fixed plate 501 is affected by the thread and moves on the threaded sleeve 602, thereby compressing the bonding spring 502 in the direction of the bonding plate 503, providing a preload force, and preparing for automatically compensating the distance between the elastic cam 3 and the tamping hammer 1.

[0038] As attached Figure 4As shown, further, the adjustment assembly 6 also includes a first support plate 603 and a second support plate 604 fixedly connected to the inside of the bearing seat 2, the threaded sleeve 602 is fixedly connected to the first support plate 603, and the push-pull rod 601 is slidably connected to the second support plate 604, wherein the first support plate 603 and the second support plate 604 are used to support the threaded sleeve 602 and the second support plate 604, thereby setting up the adjustment assembly 6.

[0039] As attached Figure 1 As shown, further, it also includes a frame 7, the frame 7 and the bearing seat 2 are provided with a through hole, a stud bolt 8 is arranged inside the through hole, and nuts 9 are respectively threadedly connected to both ends of the stud bolt 8. By tightening the nuts 9 on the stud bolt 8, the two bearing seats 2 are fixed on both sides of the frame 7, so that the two elastic cams 3 can clamp the tamping hammer 1 from both sides.

[0040] As attached Figure 1 As shown, further, the tamping hammer 1 is located in the frame 7 , and the frame 7 is provided with a through slot, the cross section of the through slot is the same as the cross section of the auxiliary slot 402 , and the elastic cam 3 passes through the through slot and fits with the tamping hammer 1 .

[0041] As can be seen from the above, the tamping hammer 1 is set in the frame 7, the stud bolt 8 passes through the frame 7 and the two bearing seats 2, and the nuts 9 are tightened on the stud bolts 8 to fix the two bearing seats 2 on both sides of the frame 7. A part of the elastic cam 3 passes through the through slot in the bearing seat 2 and extends into the frame 7, and abuts against the tamping hammer 1. The two elastic cams 3 cooperate to clamp the tamping hammer 1 from both sides.

[0042] By rotating the fixed plate 501, the fixed plate 501 will be affected by the thread and move on the threaded sleeve 602, thereby compressing the fitting spring 502 in the direction of the fitting plate 503, providing a preload force, and preparing for automatically compensating the distance between the elastic cam 3 and the tamping hammer 1. As the use time goes by, the elastic cam 3 gradually wears and its size changes due to wear. Since the preload force of the fitting spring 502 has been adjusted by the fixed plate 501 before, the fitting spring 502 will push the fitting plate 503 and the push-pull rod 601 to move, thereby pushing the sliding block 403 to move along the sliding groove 401 in the direction of the tamping hammer 1, so that the support bearing 404 and the elastic cam 3 move. The elastic cam 3 and the tamping hammer 1 continue to maintain a close fit, automatically compensating for the distance change caused by wear, and no frequent manual inspection or adjustment is required.

[0043] Embodiment 3

[0044] As attached Figure 1As shown, this embodiment is basically the same as the previous embodiment, except that it further includes a closing door 10, wherein the closing door 10 and the bearing seat 2 are fitted together to prevent coal dust from flying into the bearing seat 2 during the tamping process to affect the operation and life of the parts, and the bearing seat 2 and the closing door 10 are connected with a switch assembly 11, and the closing effect between the closing door 10 and the bearing seat 2 is ensured by the switch assembly 11.

[0045] As attached Figure 6 As shown, specifically, the switch assembly 11 includes a accommodating chamber 1101 opened on the bearing seat 2, the accommodating chamber 1101 is connected to the limiting groove 1102, and the closing door 10 is provided with a slot 1103, wherein the accommodating chamber 1101, the limiting groove 1102 and the slot 1103 constitute a closed groove, and the shape of the closed groove is adapted to the limiting frame 1104, the accommodating chamber 1101, the limiting groove 1102 and the slot 1103 are connected to the limiting frame 1104, and the limiting frame 1104 is made of elastic material. After the limiting frame 1104 is inserted into the closed groove, the closing door 10 and the bearing seat 2 can be firmly connected together, and the limiting frame 1104 is fixedly installed with a first mounting seat 1105, and the two first mounting seats 1105 are rotatably connected with a connecting rod. Plate 1106, the connecting plate 1106 is rotatably connected to the second mounting seat 1107. When the unlocking rod 1108 drives the second mounting seat 1107 to move, the inclination angle of the two connecting plates 1106 will be changed, and then the two first mounting seats 1105 will be pushed outward or pulled inward, so that the curved part of the limit frame 1104 will be opened or aggregated. The second mounting seat 1107 is fixedly connected to the unlocking rod 1108, wherein the end of the unlocking rod 1108 away from the second mounting seat 1107 passes through the limit frame 1104 and is fixedly connected to an anti-slip plate. The unlocking rod 1108 is pulled by the anti-slip plate, so that the unlocking rod 1108 slides in the limit frame 1104, and the anti-slip plate is used to prevent the unlocking rod 1108 from being separated from the limit frame 1104.

[0046] As attached Figure 6 As shown, further, the cross-section of the limit frame 1104 is in a "J" shape, the bent portion of the limit frame 1104 is located in the limit groove 1102, the width of the bent portion of the limit frame 1104 is greater than the width of the accommodating groove and the limit groove 1102, and the tail end of the bent portion of the limit frame 1104 is provided with a rounded corner. The limit frame 1104 is inserted into the closed groove so that the rounded corner of the bent portion of the limit frame 1104 is abutted against the notch of the closed groove, the bent portion of the limit frame 1104 is forced to aggregate, and then inserted into the closed groove, and the smooth portion of the limit frame 1104 is located in the accommodating cavity 1101 and the slot 1103.

[0047] As can be seen from the above, the closing door 10 is fitted with the bearing seat 2, and then the limiting frame 1104 is inserted into the closing groove. When the rounded corners of the curved part of the limiting frame 1104 are against the notch of the closing groove, the curved part of the limiting frame 1104 is deformed and aggregated by force, thereby reducing the size and being inserted into the closing groove. When the curved part of the limiting frame 1104 is inserted into the limiting groove 1102, since the space of the limiting groove 1102 is larger than the accommodating cavity 1101, the curved part is no longer restricted, and the curved part returns to its original state and is inserted into the depth of the limiting groove 1102. At this time, the limiting frame 1104 is embedded in the closing groove, thereby fixing the closing door 10 and the bearing seat 2 to prevent the flying coal dust from floating into the bearing seat 2 during the tamping process;

[0048] When the closed door 10 needs to be opened, the unlocking rod 1108 is pulled outward, and the unlocking rod 1108 drives the second mounting seat 1107 to move, changing the inclination angle of the two connecting plates 1106, and then pulling the two first mounting seats 1105 inward, so that the bent parts of the limit frame 1104 are aggregated. At this time, the bent parts are no longer restricted by the limit groove 1102. The limit frame 1104 can be pulled out of the closing groove to release the limit on the closed door 10 and the bearing seat 2.
