[0019] In this invention, the terms "first," "second," etc., are used for descriptive purposes only and do not specifically refer to any order or sequence, nor are they intended to limit the invention. They are merely used to distinguish protective components or operations described using the same technical terms, and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0020] Example 1: Please refer to Figures 1-4 A large high-speed forging machine movable crossbeam stop mechanism includes a crossbeam 1, a sliding sleeve 2 fixedly connected to the crossbeam 1, the sliding sleeve 2 slidably connected to a column 3, a stop groove 5 provided on the column 3, a stop tooth 7 provided in the stop groove 5, a stop sleeve 6 concentrically provided on the sliding sleeve 2, the stop sleeve 6 slidably connected to the column 3, and a stop insert provided on the stop sleeve 6, the stop insert being able to be inserted into the stop groove 5 and form a snap-fit ​​state with the stop tooth 7.

[0021] The working principle and beneficial effects of the above scheme are as follows: The crossbeam 1 can slide up and down along the column 3 via the sliding sleeve 2 to meet the working stroke requirements of the high-speed forging machine. When the equipment needs to be installed or repaired, the crossbeam 1 needs to be stopped and fixed. At this time, the stop sleeve 6 is rotated so that the stop insert on it is aligned with the stop groove 5, so that the stop insert is inserted into the pre-set stop groove 5 in the column 3. The stop insert and the stop teeth 7 in the stop groove 5 mesh with each other to form a snap-fit ​​state. The mechanical limiting effect of the tooth meshing restricts the downward displacement of the crossbeam 1 along the column 3, thereby realizing the crossbeam 1 can move arbitrarily along the column 3. The fixed position completely replaces the traditional method of "erecting scaffolding between the beam and the workbench" for stopping the movement. It eliminates the need for a large amount of manpower and resources to erect and dismantle scaffolding, greatly improving the efficiency of equipment installation and maintenance. The snap-fit ​​structure of the stop plug and the stop tooth 7 has strong mechanical stability, which can effectively prevent the beam 1 from falling unexpectedly and significantly improve the safety of operation. The stopping mechanism is integrated between the beam 1, the sliding sleeve 2 and the column 3. The structure is compact and does not occupy extra working space, which is suitable for the equipment layout requirements of large high-speed forging machines.

[0022] Example 2: Please refer to Figure 5 Based on Embodiment 1, the stop plug includes a fixed sleeve 8, a stop rod 9 is slidably inserted into the fixed sleeve 8, the stop rod 9 passes through the fixed sleeve 8, a sliding sleeve 13 is slidably sleeved on the outside of the fixed sleeve 8, a stop pressure block 10 is provided in the sliding sleeve 13, the stop pressure block 10 is located on one side of the fixed sleeve 8, and the stop pressure block 10 is rotatably connected to the stop rod 9.

[0023] The fixed sleeve 8 is provided with a first step, and the portion of the stop rod 9 located inside the fixed sleeve 8 is provided with a second step. A first spring 12 is provided between the first step and the second step, and the first spring 12 is sleeved on the stop rod 9.

[0024] The stop block 10 is provided with a drive handle 11, one end of which passes through the sliding sleeve 13 and is located outside the sliding sleeve 13.

[0025] The working principle and beneficial effects of the above scheme are as follows: When stopping, rotating the drive handle 11 causes the stop block 10 to rotate, and the inclined surface on the stop block 10 rotates from a misaligned state with the end face of the fixed sleeve 8 to a aligned state. Figure 5 In the fit state, under the action of the first spring 12, the stop rod 9 extends out of the stop sleeve 6 and inserts into the stop tooth 7, which can complete the stopping and unlocking without complicated tools, further improving work efficiency; the overall structure is modularly designed, which facilitates maintenance and replacement of parts and extends the service life of the stop mechanism. The limiting function of the first and second steps provides a continuous stopping thrust to the stop rod, ensuring tight engagement and preventing loosening caused by vibration.

[0026] Example 3: Please refer to Figures 6-8 Based on embodiment 1, the sliding sleeve 2 has a semi-open structure. The opening of the sliding sleeve 2 is symmetrically fixedly connected with fastening ears 14. A pressure ear 16 is provided on the outside of the fastening ear 14. A compression assembly is provided between the pressure ear 16 and the fastening ear 14. The fastening ear 14 and the pressure ear 16 are connected by a fastening shaft 15. The fastening shaft 15 is inserted into the center of the fastening ear 14 and the pressure ear 16. Limit caps 17 are provided at both ends of the fastening shaft 15. Both sets of clamping ears 16 are connected to clamping handles 18.

[0027] The extrusion assembly includes a first pressing plate 19 and a second pressing plate 24. The first pressing plate 19 is provided with a first pressing platform 21. There are two sets of the first pressing platform 21, and the two sets of the first pressing platform 21 are connected end to end. The height of the first end of the first pressing platform 21 is higher than the height of the tail end. The second pressing plate 24 is provided with a second pressing platform 26. There are two sets of the second pressing platform 26, and the two sets of the second pressing platform 26 are connected end to end. The height of the first end of the second pressing platform 26 is higher than the height of the last end. The first pressure plate 19 and the second pressure plate 24 are configured in cooperation; The first pressing platform 21 is provided with a first pressing groove, and the second pressing platform 26 is provided with a second pressing groove. A ball bearing 22 is provided in the cavity formed between the first pressing groove and the second pressing groove. The first pressure plate 19 is provided with a ball bearing cavity 23, which is connected to the cavity formed between the first pressure groove and the second pressure groove.

[0028] A transmission protrusion 20 is fixedly connected to the first pressure plate 19, and the transmission protrusion 20 is fixedly connected to the pressure lug 16; A connecting sleeve 25 is fixedly connected to the second pressure plate 24. The connecting sleeve 25 is inserted into the fastening ear 14 and fixedly connected to the fastening ear 14.

[0029] The working principle and beneficial effects of the above scheme are as follows: The sliding sleeve 2 adopts a semi-open structure, which facilitates quick installation on the column 3. The fastening lug 14 at the opening is connected to the outer clamping lug 16 through the fastening shaft 15. The limiting cap 17 restricts the axial movement of the fastening shaft 15. When the clamping handle 18 is rotated, the two sets of clamping lugs 16 rotate synchronously, driving the first clamping plate 19 to rotate through the transmission protrusion 20. The two sets of first clamping platforms 21 on the first clamping plate 19 are connected end to end and have "high head and low tail". They cooperate with the second clamping platform 26 on the second clamping plate 24 with the same structure. When the first clamping plate 19 rotates, the inclined clamping platform generates axial extrusion force through the ball bearing 22, pushing the first clamping plate 19 and the second clamping plate 24 closer together, thereby driving the fastening lug 14 to tighten, so that the semi-open sliding sleeve 2 fits tightly against the surface of the column 3, realizing the fixation of the sliding sleeve 2 and the column 3.

[0030] The semi-opening sliding sleeve 2 solves the problem of inconvenient installation and disassembly of the integral sliding sleeve, and is suitable for the on-site assembly requirements of the column of a large high-speed forging machine; the extrusion assembly converts the rotational force into a uniform axial extrusion force through the inclined plane transmission and the rolling cooperation of the ball 22, making operation easier; the setting of the ball 22 reduces the friction loss between the clamping table and extends the service life of the extrusion assembly; the sliding sleeve 2 can be quickly tightened and loosened through the clamping handle 18, which is convenient to operate. At the same time, the structure is highly stable after tightening, which can effectively prevent the relative displacement between the sliding sleeve 2 and the column 3 during the stopping process and improve the reliability of the stopping mechanism.

[0031] Example 4: Please refer to Figures 9-12 Based on Embodiment 1, the crossbeam 1 and the sliding sleeve 2 are connected by a connecting rod 4. The connecting rod 4 includes a main connecting component 27 and a secondary connecting component 28. The main connecting component 27 is provided with a plug section 30, which is plugged into the secondary connecting component 28. The secondary connecting component 28 is used to fix the crossbeam 1 and the sliding sleeve 2.

[0032] A gear 35 is rotatably connected inside the connecting main component 27. Gear 35 has rack segments 34 on both sides, which mesh with the gear 35. The rack segments 34 are slidably connected inside the connecting main component 27. A limiting groove is provided on the rack segment 34, and a limiting rod 37 is slidably connected within the limiting groove. The limiting rod 37 is fixedly connected to the connecting main component 27. A locking rod sliding groove 39 is provided on the rack segment 34, and one end of a locking rod 38 is slidably connected within the locking rod sliding groove 39. The locking rod 38 is rotatably connected to the connecting main component 27, and the end of the locking rod 38 extends out of the surface of the insertion section 30. The connecting component 28 is provided with a slot 29, and the locking rod 38 can be inserted into the slot 29; The gear 35 is provided with a rotation drive hole 36, and the connecting main component 27 is provided with a drive hole 31. The drive hole 31 is aligned with the rotation drive hole 36, and the drive hole 31 can accommodate a rotating wrench 32 inserted into the rotation drive hole 36.

[0033] A retaining tooth 40 is provided on one side of the gear 35. The retaining tooth 40 is rotatably connected to the connecting main component 27. A second spring 41 is provided on one side of the retaining tooth 40. The two ends of the second spring 41 are respectively fixedly connected to the retaining tooth 40 and the connecting main component 27. A locking block 33 is fixedly connected to the retaining tooth 40. The locking block 33 penetrates the surface of the connecting main component 27.

[0034] The working principle and beneficial effects of the above scheme are as follows: The crossbeam 1 and the sliding sleeve 2 are detachably connected by a connecting rod 4. The connecting rod 4 consists of a main connecting part 27 and a secondary connecting part 28. After the insertion section 30 of the main connecting part 27 is inserted into the secondary connecting part 28, the rotating wrench 32 is inserted into the rotation driving hole 36 of the gear 35 through the driving hole 31 of the main connecting part 27. The rotating wrench 32 drives the gear 35 to rotate, and the gear 35 meshes with the rack sections 34 on both sides, driving the rack sections 34 to slide along the limiting slide rod 37 inside the main connecting part 27. The locking rod sliding groove 39 on the rack section 34 is slidably connected to one end of the locking rod 38. When the rack section 34 moves, it pushes the locking rod 38 around the main connecting part through the inclined surface of the locking rod sliding groove 39. Rotating 27 causes the end of the locking rod 38 to extend out of the surface of the insertion section 30 and insert into the slot 29 of the connecting sub-part 28, thus fixing the connecting main part 27 and the connecting sub-part 28. The locking tooth 40 on one side of the gear 35 meshes with the gear 35 under the elastic force of the second spring 41, restricting the rotation of the gear 35 and locking the position of the locking rod 38 to prevent accidental unlocking. When disassembly is required, rotating the locking block 33 that penetrates the surface of the connecting main part 27 causes the locking tooth 40 to compress the second spring 41 and disengage from the gear 35. Rotating the wrench 32 in the opposite direction resets the rack section 34, disengaging the locking rod 38 from the slot 29 and separating the connecting main part 27 from the connecting sub-part 28. The detachable structure of the connecting rod 4 breaks the fixed connection mode between the crossbeam 1 and the sliding sleeve 2, which facilitates the disassembly, transportation, on-site installation, and subsequent maintenance and replacement of the equipment, reducing the difficulty of operation; the gear and rack transmission mechanism provides precise transmission and can synchronously drive the two side locking rods 38 and locking slots 29 to ensure the coaxiality and connection firmness of the connecting main component 27 and the connecting sub-component 28; the locking structure composed of the locking teeth 40 and the second spring 41 can effectively prevent the gear 35 from reversing due to vibration during equipment operation, avoid accidental unlocking of the connecting rod 4, and improve the reliability of the connection; the entire connection and unlocking process can be completed by simply turning the wrench 32 and the locking block 33, which is simple and efficient to operate, requires no complicated fastening tools, and is suitable for the on-site working environment of the high-speed forging machine.
