DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Example 1

[0029] An integral lifting roller device, such as Figure 1-Figure 2 As shown, it includes a support frame 1, a lifting assembly 100 is installed on the support frame 1, and also includes a detection mechanism for detecting the weight of the quenched workpiece, the detection mechanism includes a hydraulic cylinder 201, the hydraulic cylinder 201 is symmetrically fixed to the middle of the front side of the support frame 1, the telescopic end of the hydraulic cylinder 201 is fixed to a cross bar 202, and a first elastic telescopic rod 203 is symmetrically fixed to the cross bar 202. The telescopic end of the first elastic telescopic rod 203 is rotatably connected to a detection roller 204 through a mounting block, and the detection roller 204 is located on the upper side of the cross bar 202. A conveying mechanism is arranged in the support frame 1, and the detection mechanism can adjust the speed of conveying the workpiece by the conveying mechanism. The conveying mechanism includes a plurality of conveying rollers 205. A plurality of evenly distributed conveying rollers 205 are arranged in the support frame 1, and a first conical wheel 206 is symmetrically fixed to the plurality of conveying rollers 205. A second conical wheel 207 is arranged on the lower side of the first conical wheel 206. The first conical wheel 206 is used in conjunction with the second conical wheel 207. A locking mechanism for limiting the position of the second conical wheel 207 is arranged in the support frame 1.

[0030] like Figure 3-Figure 4As shown, the locking mechanism includes a positioning box 301, two groups of positioning boxes 301 are symmetrically slidably connected in the support frame 1, and each group has two. A locking plate 302 is horizontally slidably connected in the positioning box 301, and a mounting box 303 is installed at the bottom of the positioning box 301. An elastic wedge block 304 is vertically slidably connected in the mounting box 303. The elastic wedge block 304 is slidably connected to the positioning box 301 in a penetrating manner. A plurality of locking grooves used in conjunction with the elastic wedge block 304 are provided at the bottom of the locking plate 302. The elastic wedge block 304 is used to limit the position of the locking plate 302.

[0031] like Figure 4 As shown, it also includes a liquid storage bucket 401, the bottom of the installation box 303 is symmetrically fixed with an elastic telescopic shaft, the bottom end of the elastic telescopic shaft is fixed with the liquid storage bucket 401, the bottom of the elastic wedge block 304 is fixed with a vertical rod, the bottom end of the vertical rod slides through the installation box 303 and is fixed with the liquid storage bucket 401, and the bottom of the liquid storage bucket 401 is provided with a through hole for discharging quenching liquid.

[0032] like Figure 5 As shown, the conveying mechanism also includes a first strip frame 501, two first strip frames 501 are symmetrically slidably connected in the support frame 1, and the two first strip frames 501 are connected to the lifting assembly 100. A plurality of conveying rollers 205 are symmetrically rotatably connected with a mounting seat 502, and both sides of the mounting seat 502 are hinged with one end of a first connecting rod 503, and the other end of the first connecting rod 503 is hinged with a second strip frame 504, and the second strip frame 504 is located at the lower side of the two first strip frames 501, and the locking plate 302 is fixedly connected to the second strip frame 504. The second conical wheel 207 is rotatably connected to the second strip frame 504, and a horizontal shaft 505 is movably connected inside the second strip frame 504. A shaft sleeve 5041 is symmetrically rotatably connected to the detection roller 204. One end of the second connecting rod 5042 is hinged on the shaft sleeve 5041, and the other end of the second connecting rod 5042 is hinged on a positioning plate 5043. The positioning plate 5043 is through-sheathed on the cross bar 202, and a toggle shaft 506 is fixedly connected to one side of the positioning plate 5043. An L-shaped plate used in conjunction with the toggle shaft 506 is fixedly connected to one side of the second strip frame 504.

[0033] Initially, the first elastic telescopic rod 203 is in a released state, and the transmission ratio of the second conical wheel 207 to the first conical wheel 206 is at a maximum ratio. When the workpiece needs to be quenched, the workpiece is moved to the upper side of the detection roller 204 through the transport track (the transport track is a prior art and will not be described here). At this time, the hydraulic cylinder 201 is started, and the telescopic end of the hydraulic cylinder 201 extends upward, so that the cross bar 202 drives the first elastic telescopic rod 203 and the positioning plate 5043 to lift upward. Since the workpiece is located on the detection roller 204 at this time, 04, the detection roller 204 cannot be lifted upward, the gap between the cross bar 202 and the detection roller 204 is shortened, and the first elastic telescopic rod 203 begins to shrink. At this time, the second connecting rod 5042 rotates with the connection point of the shaft sleeve 5041 as the center of the circle. At this time, the two positioning plates 5043 slide away from each other, and the positioning plate 5043 drives the toggle shaft 506 to squeeze the L-shaped plate on the second strip frame 504, thereby making the two second strip frames 504 move away from each other. At this time, the height of the first strip frame 501 remains stable. When the two second strip frames 504 move away from each other, the corresponding two second conical wheels 207 are driven to move, and the two second strip frames 504 swing upward through the first connecting rod 503 with the connection point of the first connecting rod 503 and the mounting seat 502 as the center of the circle, and drive the horizontal axis 505 to move upward, so that the second conical wheels 207 are always in contact with the corresponding first conical wheels 206. After the second conical wheels 207 move, the transmission ratio with the first conical wheels 206 can be changed. At this time, the first elastic telescopic rod 203 continues to retract. The detection roller 204 slightly lifts the workpiece, and the weight detection of the workpiece is completed at this time. The above steps can conveniently change the position of the second conical wheel 207, thereby changing the transmission ratio of the second conical wheel 207 to the first conical wheel 206, so that the conveying roller 205 adjusts the rotation speed according to the weight of the workpiece, prevents the workpiece from moving out of position on the conveying roller 205 when the conveying roller 205 stops rotating due to inertia caused by the moving speed of the workpiece, and prevents the conveying roller 205 from rotating too fast, resulting in wear on the workpiece surface.

[0034] When the two second bar frames 504 swing upward away from each other, the second bar frames 504 drive the corresponding locking plates 302 to swing upward, and the locking plates 302 squeeze the corresponding positioning boxes 301 and slide in the positioning boxes 301. The positioning boxes 301 are forced to slide upward along the support frame 1, and at the same time, several locking grooves at the bottom of the locking plates 302 squeeze the adjacent elastic wedge blocks 304, causing the elastic wedge blocks 304 to continuously shrink and slide. When the two second bar frames 504 no longer move, the locking plates 302 no longer move, and the elastic wedge blocks 304 are stuck in the several locking grooves at the bottom of the locking plates 302 to limit the locking plates 302, thereby limiting the two second bar frames 504, so that the transmission of the second conical wheel 207 and the first conical wheel 206 The dynamic ratio no longer changes, and then the driving assembly is started (the driving assembly is composed of a driving motor, a chain or a belt, all of which are prior art, not shown in the figure, and will not be described again here) to drive the second conical wheel 207 to rotate, and the second conical wheel 207 drives the first conical wheel 206 to rotate by friction with the first conical wheel 206, and the first conical wheel 206 drives the corresponding conveying roller 205 to rotate to move the workpiece to the center position between the two second strip frames 504, and then the lifting assembly 100 is started (the lifting assembly 100 is a winch or other equipment, and is prior art, and will not be described again here), the lifting assembly 100 drives the two first strip frames 501 to descend, so that the conveying roller 205 drives the horizontal axis 505 and the workpiece to descend into the quenching pool for quenching. Example 2

[0035] like Figure 6 As shown, it also includes a piston cylinder 601. The inner walls of several conveying rollers 205 are rotatably connected to the piston cylinder 601. The inner cavity of the piston cylinder 601 is filled with thermal expansion gas. When the workpiece is located on the surface of the several conveying rollers 205, the high temperature of the workpiece can be transmitted to the inner cavity of the piston cylinder 601 through the several conveying rollers 205. The telescopic end of the piston cylinder 601 is fixedly connected to the second elastic telescopic rod 602.

[0036] like Figure 6-Figure 7 As shown, it also includes a rack 701, one end of the second elastic telescopic rod 602 is fixedly connected to the rack 701, and the outer walls of one end of several conveying rollers 205 are rotatably sleeved with a mounting frame 702, the mounting frame 702 is located on one side of the mounting seat 502, and an elastic limiting pin 703 is vertically slidably connected to the mounting frame 702. A limiting hole used in conjunction with the elastic limiting pin 703 is opened on the rack 701, and the top of the elastic limiting pin 703 is fixedly connected to the first floating plate 704.

[0037] like Figure 7As shown, it also includes a gear 801, one side of the rack 701 is meshed with the gear 801, the top of the gear 801 is connected to a transmission assembly 802, the transmission assembly 802 is composed of a transmission shaft, a first bevel gear, a second bevel gear and an L-shaped frame, wherein the transmission shaft is rotatably connected to the mounting frame 702 in a through-type manner, the first bevel gear is fixed to the top of the transmission shaft, the second bevel gear is located on the upper side of the first bevel gear and meshed with the first bevel gear, the L-shaped frame is rotatably sleeved on the transmission shaft, the axle of the impeller 803 is rotatably connected to the L-shaped frame, and the second bevel gear is fixed to the axle of the impeller 803.

[0038] like Figure 8 As shown, it also includes a fixed shaft 901, a fixed shaft 901 is fixedly connected in the mounting frame 702, the fixed shaft 901 is fixedly connected to the first strip frame 501, the rack 701 is horizontally slidably connected to the inner wall of the fixed shaft 901, a guide plate 902 is fixedly connected to the top of the fixed shaft 901, a vertical slide groove is penetrated through the outer wall of the guide plate 902, a slider 903 is slidably connected in the vertical slide groove, an elastic member is arranged between the slider 903 and the guide plate 902, the elastic member is a tension spring, a T-shaped frame 904 is fixedly connected to one side of the slider 903 through a convex shaft, a sliding shaft 905 is slidably connected in the T-shaped frame 904, one end of the sliding shaft 905 is hinged to a second extension rod 906, a slide rail 907 is installed on one side of the L-shaped frame in the transmission assembly 802, one end of the second extension rod 906 is stuck in the slide rail 907 and slides in the slide rail 907.

[0039] like Figure 8 As shown, a second floating plate 908 is also included. The top of the T-shaped frame 904 is fixedly connected to the second floating plate 908. A guide groove for cooperating with the sliding shaft 905 is opened on the guide plate 902. When the sliding shaft 905 slides along the guide groove, the L-shaped frame in the transmission assembly 802 can drive the impeller 803 to swing.

[0040] like Figure 2 and Fig. 9 As shown, it also includes a guide box 1001, and the guide box 1001 is symmetrically fixed on one side of the support frame 1, a Z-shaped plate 1002 is slidably connected inside the guide box 1001, the detection roller 204 is rotatably connected to the Z-shaped plate 1002, and a trigger switch 1003 used in conjunction with the Z-shaped plate 1002 is installed on the top of the inner wall of the guide box 1001, the trigger switch 1003 is electrically connected to the hydraulic cylinder 201, and when the Z-shaped plate 1002 squeezes the trigger switch 1003, the hydraulic cylinder 201 is closed.

[0041] When detecting the weight of the workpiece, it is necessary to make the detection roller 204 slightly lift the workpiece. If the workpiece is lifted too high, the workpiece will shake when moving, causing the workpiece to be misplaced or collide and wear. The staff cannot accurately judge whether the workpiece is lifted up just by visual observation. When the detection roller 204 slightly lifts the workpiece, the detection roller 204 drives the Z-shaped plate 1002 to slightly lift. After the Z-shaped plate 1002 is lifted, it squeezes the trigger switch 1003 to close the hydraulic cylinder 201, thereby preventing the workpiece from being lifted too high.

[0042] Before the workpiece sinks into the quenching pool, it has an extremely high temperature. When the workpiece moves onto the conveying roller 205, the conveying roller 205 conducts the high temperature of the workpiece to the piston cylinder 601 inside it. The hot expansion gas in the piston cylinder 601 expands due to the heat, causing the telescopic end of the piston cylinder 601 to extend. The telescopic end of the piston cylinder 601 drives the second elastic telescopic rod 602 to move. At this time, the elastic limiting pin 703 is inserted into the limiting hole of the rack 701 to limit the rack 701, and the rack 701 cannot move, thereby causing the telescopic end of the second elastic telescopic rod 602 to contract. When the workpiece sinks into the quenching pool, the first floating plate 704 contacts the liquid in the quenching pool. The liquid in the quenching pool applies buoyancy to the first floating plate 704. The first floating plate 704 drives the elastic limiting pin 703 to lift and slide upward. After sliding, the elastic limiting pin 703 disengages from the limiting hole of the rack 701. The rack 701 is freed from the restriction and can move. At this time, the telescopic end of the second elastic telescopic rod 602 is released and drives the rack 701 to slide horizontally. The rack 701 drives the transmission shaft in the transmission assembly 802 to rotate through the gear 801. The transmission shaft The first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the impeller 803 to rotate. After the impeller 803 rotates, the liquid in the quenching pool can be stirred, so that the liquid in the quenching pool flows on the surface of the workpiece, thereby improving the quenching effect of the workpiece. Then, the second floating plate 908 contacts the liquid in the quenching pool, and the liquid in the quenching pool exerts buoyancy on the second floating plate 908, so that the second floating plate 908 drives the T-shaped frame 904 to lift upward, and the T-shaped frame 904 drives the adjacent slider 903 to slide upward through the convex shaft, and drives the slider inside it. The shaft 905 slides upward, and at this time, the elastic member between the slider 903 and the guide plate 902 is extended by force, and the sliding shaft 905 slides upward along the guide groove of the guide plate 902 and slides horizontally in the T-shaped frame 904. The sliding shaft 905 drives the second extension rod 906 to swing back and forth, and the second extension rod 906 drives the L-shaped frame in the transmission assembly 802 to rotate with the connection point of the transmission shaft as the center of the circle. The L-shaped frame drives the impeller 803 to swing back and forth, which can make the liquid in the quenching pool be stirred in a larger range when the impeller 803 rotates, thereby further improving the quenching effect.

[0043] At the same time, the liquid storage bucket 401 sinks into the liquid in the quenching pool. When quenching is completed, the lifting assembly 100 drives the two first strip frames 501 to lift up and lift the workpiece upward out of the quenching pool. At this time, the liquid storage bucket 401, the first floating plate 704 and the second floating plate 908 are all separated from the liquid in the quenching pool. The quenching liquid is retained in the liquid storage bucket 401. The liquid storage bucket 401 falls under the influence of the quenching liquid. The liquid storage bucket 401 drives the elastic telescopic shaft to fall, and drives the elastic wedge block 304 to shrink and slide through the vertical rod. After the elastic wedge block 304 shrinks, it disengages from several locking grooves of the locking plate 302. The locking plate 302 is free from the restriction and can move, thereby causing the two second strip frames 504 to fall and reset, and The second conical wheel 207 is reset, and the transmission ratio of the second conical wheel 207 to the first conical wheel 206 is restored to the maximum ratio. Then, the quenching liquid is gradually discharged through the through hole of the liquid storage bucket 401. The liquid storage bucket 401 is lifted and reset by the elastic telescopic shaft, and the elastic wedge block 304 is slid and reset. The temperature of the workpiece drops, and the surface of the workpiece is no longer easily worn. The gas in the piston cylinder 601 cools and contracts, and the telescopic end of the piston cylinder 601 contracts, thereby sliding and resetting the rack 701. The first floating plate 704 is no longer affected by buoyancy, and the elastic limiting pin 703 is contracted and inserted into the limiting hole of the rack 701 again to limit the rack 701, thereby completing the quenching of the workpiece.
