Description

Technical Field

[0001] The present invention relates to the technical field of stepping machinery, and particularly relates to a stepping water-cooled steel discharging machine. Background Art

[0002] A mechanical steel discharging machine is a device used to smoothly and quickly push the steel billets heated in a heating furnace onto the discharging roller table, and is widely used in a rolling mill workshop. Its working process is generally as follows: the walking beam in the heating furnace conveys the steel billets towards the furnace head (the discharging side), the photoelectric detector at the furnace head detects the signal of the steel billet, the conveying process in the furnace terminates, the discharging furnace door opens, the steel discharging machine advances under the slab at the furnace head in the furnace, the steel grabbing arm rises to receive the slab, then holds the steel billet and retreats outside the furnace, and then descends to place the steel billet on the outside roller table. The whole process is usually in an automatic control mode; When the push rod of the existing steel discharging machine is cooled, generally two methods are used. One is the conventional cooling method, and the other is to cool the inside of the push rod through a circulating water system. However, the conventional cooling method usually relies on air cooling outside the furnace. Since the slider needs to bear weight and the slider and the cross beam are welded, high temperature and large stress often cause the slider to be welded and fall off. When using the circulating water system, because the push rod itself moves reciprocally, in terms of pipeline layout, it will not only occupy a large space. At the same time, during actual use, the pipeline will move along different trajectories due to the movement of the push rod, and phenomena such as pipeline entanglement, bending, and fracture may occur, which will affect the cooling work of the push rod; In addition, the rear ends of the existing steel discharging machines are all set in an exposed manner. This design method not only easily causes personal injury or the steel discharging machine to move beyond the stroke or deviate, resulting in equipment damage, but also makes the steel discharging machine itself extremely vulnerable to external factors such as dust, water vapor, and corrosive gases, and affects the transmission performance and accuracy of the steel discharging machine.

A cooling medium injection pipe 44 and a cooling medium output pipe 45 are arranged on one side of the top of the protective cover 4 close to the transmission support assembly 1. The bottoms of the cooling medium injection pipe 44 and the cooling medium output pipe 45 both pass through the protective cover 4 and are connected with insertion ends 46. A first flow hole 47 is circumferentially formed on the lower end surface of the insertion end 46. Injection grooves 51 and output grooves 52 respectively matched with the cooling medium injection pipe 44 and the cooling medium output pipe 45 are formed at the top end of the push rod 5. Two cooling pipes 59 are arranged inside the push rod. One ends of the two cooling pipes 59 are respectively communicated with the injection groove 51 and the output groove 52, and the other ends are respectively connected with both ends of a cooling channel 53. Installation plates 54 are arranged below the injection grooves 51 and the output grooves 52. Springs 55 are arranged on the tops of the installation plates 54. Sealing balls 56 are arranged on the tops of the springs 55. A conical groove 57 matched with the sealing ball 56 and used for inserting the insertion end 46 is formed at the top of the injection groove 51 and on the top surface of the push rod 5. A plurality of uniformly distributed second flow holes 541 are formed on the installation plates 54; The arrangement of the protective cover 4 and the limiting and auxiliary sliding members 43 can realize the protection work and guiding work of the end of the push rod 5, and enable the end of the push rod 5 to move along a preset track. The cooperation of the cooling medium injection pipe 44, the cooling medium output pipe 45, the injection grooves 51 and the output grooves 52 can realize injecting the cooling medium into the cooling channel 53 and cooling the push rod 5. Among them, the connection mode of the cooling medium injection pipe 44, the cooling medium output pipe 45, the injection grooves 51 and the output grooves 52 adopts an insertion-type connection mode, which can effectively avoid the difficulty in pipeline layout. At the same time, it is convenient for the staff to decide the use of the cooling medium according to the temperature of the push rod 5, avoiding the generation of resource waste. In addition, during the use of the push rod 5, the arrangement of the springs 55 and the sealing balls 56 can realize the sealing work of the injection grooves 51 and the output grooves 52, and enable the cooling medium to stay in the cooling channel 53, so that during the use of the push rod 5, the cooling medium can be maximally utilized and the cooling efficiency of the push rod 5 itself can be increased; In this embodiment, the arrangement of the first flow hole 47 and the second flow hole 541 can ensure the circulation of the cooling medium for reuse; In this embodiment, the cooling medium injection pipe 44 and the cooling medium output pipe 45 are both connected to an external circulating cooling system, so as to ensure the circulation of the cooling medium itself for reuse.

[0018] As Figure 13 shown, a communication hole is formed in the middle of the mounting plate 54. Inside the communication hole and on the inner side of the spring 55, a movable rod 542 is movably connected. The top of the movable rod 542 is connected to the sealing ball 56, and the bottom of the movable rod 542 is fixedly provided with a limiting plate 543 below the mounting plate 54; The arrangement of the movable rod 542, the communication hole and the limiting plate 543 can make the sealing ball 56 move along a preset track when it is forced to move downward. This can not only effectively avoid the bending of the spring 55, but also further increase the accuracy of the movement position of the sealing ball 56 after the spring 55 is reset, and ensure the sealing of the injection groove 51 and the output groove 52 itself.

[0019] As Figure 9 shown, a plurality of uniformly distributed first fixing holes 58 are formed on one side of the top of the push rod 5 away from the transmission support assembly 1. A slider 6 is arranged on the top of the push rod 5. A second fixing hole 61 matching the first fixing hole 58 is formed in the slider 6. A bolt 62 is threadedly connected between the first fixing hole 58 and the second fixing hole 61, and a sealing ring 63 is arranged between the first fixing hole 58 and the second fixing hole 61; The arrangement of the first fixing hole 58, the second fixing hole 61 and the bolt 62 can facilitate the installation and disassembly of the slider 6 by the staff, so as to facilitate the replacement of the damaged slider 6 by the staff.

[0020] As Figure 9 shown, a groove 64 is formed on the push rod 5 below the first fixing hole 58, and a round groove 65 communicating with the cooling channel 53 is formed at the bottom of the groove 64; The arrangement of the groove 64 and the round groove 65 can make a certain amount of cooling medium in the cooling channel 53 flow into the groove 64 and realize the cooling of the bolt 62. In this way, not only the service life of the bolt 62 itself can be effectively extended, but also the damage to the bolt 62 caused by high temperature can be further reduced, and the sealing ring 63 can effectively prevent the leakage of the cooling medium.

[0021] As Figures 3-5As shown, the limiting and assisting sliding member 43 includes a plurality of limiting sliding seats 431 arranged on the inner wall of the protective cover. An L-shaped plate 432 is slidably connected within the limiting sliding seat 431. An assisting wheel 433 is rotatably connected to one side of the L-shaped plate 432. An elastic member 434 is arranged between the rear end of the L-shaped plate 432 and the inner wall of the protective cover 4. The arrangement of the assisting wheel 433 can play a role in assisting the push rod 5 during the operation of the push rod 5. At the same time, it can also limit the movement range of the push rod 5 itself and ensure the accuracy of the movement of the push rod 5 itself. In this embodiment, the arrangement pattern of the plurality of limiting and assisting sliding members 43 is such that the limiting and assisting sliding member 43 closer to the transmission support assembly 1 is first inclined, and then the plurality of limiting and assisting sliding members 43 on the side away from the transmission support assembly 1 are arranged in a straight line. The advantage of arranging the plurality of limiting and assisting sliding members 43 in this type of layout is that it can provide a basis for the inclined insertion operation of the push rod 5.

[0022] In this embodiment, both the elastic member and the buffer elastic body are made of silicone rubber plates. In this embodiment, the rotation structure used by the assisting wheel is an existing rotation structure, such as a hinge structure, a bearing, etc.

[0023] As Figure 10 shown, a radian end 3 is provided on one side of the bottom of the push rod 5, and a rack end 2 is provided on the other side of the bottom of the push rod 5. The transmission support assembly 1 includes a first fixed seat 11 connected to the ground, and a gear shaft 12 arranged on the first fixed seat 11 and meshing with the rack end 2. A driving motor connected to the ground and used to drive the gear shaft 12 is provided on one side of the first fixed seat 11. A lifting wheel 13 is provided on the top of the first fixed seat 11 and on the side of the gear shaft 12. A lifting member connected to the bottom of the lifting wheel 13 is arranged within the first fixed seat 11. The arrangement of the driving motor can drive the gear shaft 12 to rotate, thereby causing the meshing rack end 2 to translate, thus completing the forward or backward movement operation of the push rod 5. The arrangement of the lifting member can lift the push rod 5 upward after the push rod 5 moves to the left end and is limited by the baffle, and enable the push rod 5 to complete the connection work with the injection groove 51, the output groove 52, the cooling medium injection pipe 44, and the cooling medium output pipe 45, and ensure the progress of the cooling medium usage work.

[0024] As Figure 12As shown, the lifting assembly 7 includes a second fixed seat 71 connected to the ground, a pushing member 72 disposed on the top of the second fixed seat 71 and hinged to the second fixed seat 71, and a third fixed seat 73 disposed on one side of the second fixed seat 71 and connected to the ground. A transmission crank 74 is hingedly connected to the third fixed seat 73. One end of the transmission crank 74 abuts against the arc end 3, and the other end of the transmission crank 74 is hinged to the output end of the pushing member 72; The setting of the lifting assembly 7 can lift and lower the end of the push rod 5 during the movement of the push rod 5, so as to ensure the carrying and placing of the billet by the push rod 5 and the slider 6, and realize the unloading of the billet; In this embodiment, the pushing member 72 includes an existing hydraulic push rod.

[0025] Working principle: First of all, the driving motor will drive the push rod 5 to move forward. After the end of the push rod 5 moves to the specified position, the output end of the pushing member 72 will push one end of the transmission crank 74, and the other end of the transmission crank 74 will jack up the end of the push rod 5, and the slider 6 will gradually complete the carrying work of the billet. After the billet is carried, the driving motor and the transmission crank 74 will drive the push rod 5 to move left and down respectively, and place the billet on the external transmission roller. Then when the push rod abuts against the baffle 41, the pushing member 72 contracts to the initial position. After the pushing member 72 is reset, the pushing member 72 will further lift one end of the push rod 5 through the transmission crank 74. At the same time, the lifting member will synchronously drive the jacking wheel to jack up the other end of the push rod 5, and the insertion ends 46 at the bottoms of the cooling medium injection pipe 44 and the cooling medium output pipe 45 will be inserted into the tapered grooves on the injection groove 51 and the output groove 52 respectively, and simultaneously apply a downward pressure to the sealing ball 56, and the spring 55 will retract. After the insertion end 46 is inserted, the cooling medium will flow into the cooling channel 53 through the cooling medium injection pipe 44, the first flow hole 47 and the second flow hole 541, and flow along the cooling channel 53, and finally flow through the second flow hole 541 and the first flow hole 47 in the output groove 52 into the cooling medium output pipe 45, and flow through the cooling medium output pipe 45 to the external cooling tower for cooling treatment. Among them, after the push rod 5 moves to the left end and is limited by the baffle, the top of the push rod 5 will contact the bottom of the upper end of the L plate 432, and the movement of the push rod 5 will synchronously make the L plate 432 move upward along the limiting slide.

[0026] It should be noted that the present invention only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present invention.

[0027] Of course, the present invention may have many other embodiments. Based on this embodiment, other embodiments obtained by those of ordinary skill in the art without any creative work fall within the scope of protection of the present invention.
