The two seat bearings 23 are connected by positive and negative thread screws 24, and moving components 25 are rotatably installed on the positive and negative thread screws 24 and near the two ends. The two moving components 25 pass through the sliding hole 22, and the two side walls of each moving component 25 are provided with locking components 26. The top surface of the support plate 21 and the two sides of the sliding hole 22 are provided with limiting grooves 27, and the inner cavity of each limiting groove 27 is provided with a limiting strip 28, and a plurality of sawtooth blocks 29 are provided on both sides of the top surface of each limiting strip 28. The sawtooth stopper 29 is in a right triangle shape. Second stepped holes 210 are provided on both sides and the middle of the top surface of each limit bar 28. A second fixing screw 211 is inserted into the inner cavity of each second stepped hole 210. The bottom end of the second fixing screw 211 is connected to the rotation of the support plate 21. A driving component 212 is provided on the outer wall of each locking component 26 and one side of the top surface of the support plate 21. The output end of one driving component 212 is connected to one end of the positive and negative thread screw 24, and the output ends of the other four driving components 212 are connected to the input end of the locking component 26. An anti-falling component 213 is provided on the bottom surface of the support plate 21, and the anti-falling component 213 passes through the two moving components 25. The support plate 21 in the propping mechanism 2 can provide space for the sliding hole 22 and the two limit grooves 27, and can also install and fix two seat bearings 23 and a driving component 212. Since the two seat bearings 23 are connected by the positive and negative threaded screws 24, and the moving components 25 are rotatably installed on the positive and negative threaded screws 24 and near the two ends, and one end of the positive and negative threaded screws 24 is connected to the output end of the driving component 212 located on the support plate 21, when the driving component 212 is running, it can synchronously drive the positive and negative threaded screws 24 to rotate on the two seat bearings 23, so that the two moving components 25 can be moved closer to or separated from the middle. Since the top and bottom ends of the two moving components 25 are respectively connected to the four supporting mechanisms 3, when the two moving components When the components 25 are separated to both sides, the two moving components 25 will synchronously drive the corresponding lifting mechanisms 3 to move outward, thereby gradually increasing the angle between the lifting mechanisms 3 and the support plate 21, so that the lifting mechanisms 3 can lift the top plate 11 to rise. The second step hole 210 can be penetrated by the second fixing screw 211, so that the limiting strip 28 inserted in the limiting groove 27 can be installed and fixed in the inner cavity of the limiting groove 27, thereby improving the stability of the use of the limiting strip 28. Since the top surface of each limiting strip 28 is provided with symmetrically distributed serrated blocks 29, and the two side walls of each moving component 25 are provided with locking components 26, and the bottom end of the locking component 26 elastically rests between the two serrated blocks 29, and each locking component 26 A driving assembly 212 is installed at the top, so when the moving assembly 25 moves outward, the locking assembly 26 can move along the multiple serrated blocks 29, so that the locking assembly 26 will not be blocked, and the driving assembly 212 located on the locking assembly 26 will not run. When the hydraulic actuator needs to be locked, the driving assembly 212 located at one end of the positive and negative threaded screw 24 will stop running first, and the locking assembly 26 will be stuck at the serrated block 29 at the current position, so that the serrated block 29 at the current position will be against the bottom of the locking assembly 26. At the same time, the four lifting mechanisms 3 are distributed in a "》《" manner, so the moving assembly 25 is in a stable state, so the four lifting mechanisms 3 can steadily lift the top plate 11 to ensure that the hydraulic actuator remains Stable. When the hydraulic actuator needs to be lowered, the driving component 212 on the locking component 26 is first opened, so that the bottom end of the locking component 26 can be driven away from the serrated block 29, and then the driving component 212 at one end of the forward and reverse screw 24 is opened, so that the driving component 212 can drive the forward and reverse screw 24 to run in the opposite direction, and then drive the two moving components 25 to move closer to the middle, so that the hydraulic actuator can be smoothly lowered. Since the anti-falling component 213 is provided on the bottom surface of the support plate 21, and the anti-falling component 213 passes through the two moving components 25, the anti-falling component 213 can be used to assist in supporting the left and right movement of the two moving components 25, thereby improving the stability of the movement of the moving component 25.

[0023] See also Figure 7 , Figure 8 The moving assembly 25 includes a moving block 251, and a first screw hole 252 rotatably mounted with the positive and negative threaded screw 24 is opened on the outer wall of the moving block 251 and located in the middle and upper position, and a slot 253 is opened at the top and bottom of the moving block 251, and a first through hole 254 is opened on the outer wall of the moving block 251 and close to the bottom and the top, and the inner cavities of the two first through holes 254 are installed with first connecting bolts 255, and a guide hole 256 for penetrating the anti-falling assembly 213 is opened on the outer wall of the moving block 251 and located in the middle and lower position, and a second through hole 257 is opened on the other side wall of the moving block 251 and located on the outer side of the guide hole 256, wherein the inner cavity of the second through hole 257 is provided with a second connecting bolt 258, and a roller 259 is inserted on the second connecting bolt 258 and located in the inner cavity of the guide hole 256; The moving block 251 in the moving component 25 can slide in the inner cavity of the sliding hole 22, and can be rotatably connected with the forward and reverse threaded screw 24 through the first screw hole 252. At the same time, it can provide space for the two slots 253 and multiple first through holes 254 and the guide hole 256 and multiple second through holes 257. In addition, the first connecting bolt 255 cooperates with the first through hole 254 to install and fix one end of the lifting mechanism 3 inserted in the slot 253, so that the forward and reverse threaded screw 24 can drive the moving block 251 to move while synchronously driving the lifting mechanism 3 to rise. Through the second through hole 257, the roller 259 can be installed in the inner cavity of the guide hole 256 in cooperation with the second connecting bolt 258, and the roller 259 can also roll on the second connecting bolt 258, so that the anti-fall component 213 can provide lifting support for the moving block 251.

[0024] See also Figure 7 , Fig. 9 The locking assembly 26 includes a guide frame 261 arranged on the outer wall of the moving assembly 25, a locking tongue 262 is vertically inserted on the guide frame 261, a square groove 263 is provided on the top surface of the locking tongue 262, a square block 264 is movably inserted in the inner cavity of the square groove 263, a second screw hole 265 is provided at the center of the top surface of the square block 264, a one-way screw rod 266 is rotatably installed in the inner cavity of the second screw hole 265, and the top end of the one-way screw rod 266 is connected to the output end of the driving assembly 212, the bottom end of the square block 264 is connected to the bottom surface of the inner cavity of the square groove 263 through a spring 267, guide holes 268 are provided on both side walls of the locking tongue 262, and the guide holes 268 are conductively connected to the inner cavity of the square groove 263, and a second internal thread groove 269 is provided on the outer wall of the guide frame 261; The guide frame 261 in the locking assembly 26 can be fixed to the outer wall of the moving block 251 and can also be movably inserted and installed on the lock tongue 262. Since the outer wall of the bottom end of the lock tongue 262 fits with the inclined surface of the right-angled triangle sawtooth block 29, as shown in FIG. Figure 5 As shown, when the moving block 251 moves outward, the locking tongue 262 will move along the serrated blocks 29 on the same side, and the locking tongue 262 will not be blocked in this process. At the same time, the other side of the locking tongue 262 will abut against the right angle surface of the serrated block 29 in a right triangle, so the locking tongue 262 will be blocked from moving inward. Since the hydraulic actuator will provide downward pressure on the top plate 11, when the positive and negative threaded screws 24 do not rotate, the locking tongue 262 will not move outward. Therefore, in this state, the locking tongue 262 has the purpose of locking and limiting the moving block 251. Even if the pressure in the hydraulic system disappears, the hydraulic actuator will not move. When the hydraulic actuator needs to drop, the inner cavity of the square groove 263 is movably connected with the square block 264.

At this time, the one-way screw 266 can be driven to rotate through the driving component 212, so that the block 264 can be driven to move upward through the second screw hole 265, and then under the pull of the spring 267, the locking tongue 262 can be synchronously driven to move upward, so that the bottom end of the locking tongue 262 can be raised above the serrated block 29, so that the locking tongue 262 releases the limit on the moving block 251, and then by driving the forward and reverse thread screws 24 to run in the opposite direction, the moving block 251 can be driven to move to the middle, so that the lifting mechanism 3 can be folded, which is convenient for the hydraulic actuator to descend.

At least one outer wall of the pressure-resistant sealing box 2121 is provided with a stabilizing seat 2125. The outer wall of the pressure-resistant sealing box 2121 is inlaid with a junction box 2126.

Since the second double-ear fixing seat 35 is installed at the other end of the arm 31, and the bottom end of the second double-ear fixing seat 35 is inserted into the slot 253 on the moving block 251 through the insert block 36, and the first connecting bolt 255 passes through the sixth through hole 37 on the insert block 36, the first connecting bolt 2 55, so that the plug block 36 can be stably and firmly installed on the moving block 251, thereby ensuring the stability of the connection between the second double-ear fixing seat 35 and the moving block 251, and through the movement of the moving block 251, the support arm 31 can be supported under the connection of the first double-ear fixing seat 32, the support arm 31 and the second double-ear fixing seat 35. Since the inner cavity of the first double-ear fixing seat 32 and the second double-ear fixing seat 35 and the two ends of the support arm 31 are provided with arc-shaped blocks 38, the arc-shaped blocks 38 can play a role in stably transmitting the supporting force of the support arm 31 on the first double-ear fixing seat 32 and the second double-ear fixing seat 35.

[0029] When in use: through the jacking mechanism 1 and the positioning mechanism 4, they can be installed on the bottom surface of the hydraulic actuator and the bottom surface of the inner cavity of the hydraulic cylinder body respectively. Since the lifting mechanisms 3 are arranged on both sides of the bottom surface of the jacking mechanism 1 and the top surface of the positioning mechanism 4, and the four lifting mechanisms 3 are connected to the output end of the supporting mechanism 2, and the two lifting mechanisms 3 at the same height are symmetrically distributed, when the hydraulic actuator is raised, the supporting mechanism 2 will start to run synchronously, and then the supporting mechanism 2 can synchronously drive the four lifting mechanisms 3 to move, so that the two lifting mechanisms 3 at the same height can be gradually moved away, and then the lifting mechanism 3 can support the hydraulic actuator through the jacking mechanism 1, and when the hydraulic actuator needs to be locked, it is only necessary to open the locking state of the supporting mechanism 2, so that the four lifting mechanisms 3 can support the hydraulic actuator, so that even if the pressure in the hydraulic system disappears, the hydraulic actuator will not move, thereby ensuring the stability of the hydraulic actuator support, and the four symmetrically distributed lifting mechanisms 3 can increase the locking distance of the hydraulic actuator, thereby increasing the scope of use of the equipment.

[0030] Through the multiple first fixing screws 13 in the lifting mechanism 1, they can be respectively inserted into the first stepped holes 12 at the corresponding positions, and can also be rotatably installed on the bottom surface of the hydraulic actuator, so that the top plate 11 can be stably and firmly fixed on the bottom surface of the hydraulic actuator. Through the first card groove 14 and the first internal thread groove 15 on the top plate 11, the lifting mechanism 3 installed on the top plate 11 can be installed and fixed, thereby improving the stability of the lifting mechanism 3 lifting the top plate 11.

[0031] The support plate 21 in the propping mechanism 2 can provide space for the sliding hole 22 and the two limit grooves 27, and can also install and fix two seat bearings 23 and a driving component 212. Since the two seat bearings 23 are connected by the positive and negative threaded screws 24, and the moving components 25 are rotatably installed on the positive and negative threaded screws 24 and near the two ends, and one end of the positive and negative threaded screws 24 is connected to the output end of the driving component 212 located on the support plate 21, when the driving component 212 is running, it can synchronously drive the positive and negative threaded screws 24 to rotate on the two seat bearings 23, so that the two moving components 25 can be moved closer to or separated from the middle. Since the top and bottom ends of the two moving components 25 are respectively connected to the four supporting mechanisms 3, when the two moving components When the components 25 are separated to both sides, the two moving components 25 will synchronously drive the corresponding lifting mechanisms 3 to move outward, thereby gradually increasing the angle between the lifting mechanisms 3 and the support plate 21, so that the lifting mechanisms 3 can lift the top plate 11 to rise. The second step hole 210 can be penetrated by the second fixing screw 211, so that the limiting strip 28 inserted in the limiting groove 27 can be installed and fixed in the inner cavity of the limiting groove 27, thereby improving the stability of the use of the limiting strip 28. Since the top surface of each limiting strip 28 is provided with symmetrically distributed serrated blocks 29, and the two side walls of each moving component 25 are provided with locking components 26, and the bottom end of the locking component 26 elastically rests between the two serrated blocks 29, and each locking component 26 A driving assembly 212 is installed at the top, so when the moving assembly 25 moves outward, the locking assembly 26 can move along the multiple serrated blocks 29, so that the locking assembly 26 will not be blocked, and the driving assembly 212 located on the locking assembly 26 will not run. When the hydraulic actuator needs to be locked, the driving assembly 212 located at one end of the positive and negative threaded screw 24 will stop running first, and the locking assembly 26 will be stuck at the serrated block 29 at the current position, so that the serrated block 29 at the current position will be against the bottom of the locking assembly 26. At the same time, the four lifting mechanisms 3 are distributed in a "》《" manner, so the moving assembly 25 is in a stable state, so the four lifting mechanisms 3 can steadily lift the top plate 11 to ensure that the hydraulic actuator remains Stable. When the hydraulic actuator needs to be lowered, the driving component 212 on the locking component 26 is first opened, so that the bottom end of the locking component 26 can be driven away from the serrated block 29, and then the driving component 212 at one end of the forward and reverse screw 24 is opened, so that the driving component 212 can drive the forward and reverse screw 24 to run in the opposite direction, and then drive the two moving components 25 to move closer to the middle, so that the hydraulic actuator can be smoothly lowered. Since the anti-falling component 213 is provided on the bottom surface of the support plate 21, and the anti-falling component 213 passes through the two moving components 25, the anti-falling component 213 can be used to assist in supporting the left and right movement of the two moving components 25, thereby improving the stability of the movement of the moving component 25.

[0032] The moving block 251 in the moving component 25 can slide in the inner cavity of the sliding hole 22, and can be rotatably connected with the forward and reverse threaded screw 24 through the first screw hole 252. At the same time, it can provide space for the two slots 253 and multiple first through holes 254 and the guide hole 256 and multiple second through holes 257. In addition, the first connecting bolt 255 cooperates with the first through hole 254 to install and fix one end of the lifting mechanism 3 inserted in the slot 253, so that the forward and reverse threaded screw 24 can drive the moving block 251 to move while synchronously driving the lifting mechanism 3 to rise. Through the second through hole 257, the roller 259 can be installed in the inner cavity of the guide hole 256 in cooperation with the second connecting bolt 258, and the roller 259 can also roll on the second connecting bolt 258, so that the anti-fall component 213 can provide lifting support for the moving block 251.

[0033] The guide frame 261 in the locking assembly 26 can be fixed to the outer wall of the moving block 251 and can also be movably inserted and installed on the lock tongue 262. Since the outer wall of the bottom end of the lock tongue 262 fits with the inclined surface of the right-angled triangle sawtooth block 29, as shown in FIG. Figure 5 As shown, when the moving block 251 moves outward, the locking tongue 262 will move along the serrated blocks 29 on the same side, and the locking tongue 262 will not be blocked in this process. At the same time, the other side of the locking tongue 262 will abut against the right angle surface of the serrated block 29 in a right triangle, so the locking tongue 262 will be blocked from moving inward. Since the hydraulic actuator will provide downward pressure on the top plate 11, when the positive and negative threaded screws 24 do not rotate, the locking tongue 262 will not move outward. Therefore, in this state, the locking tongue 262 has the purpose of locking and limiting the moving block 251. Even if the pressure in the hydraulic system disappears, the hydraulic actuator will not move. When the hydraulic actuator needs to drop, the inner cavity of the square groove 263 is movably connected with the square block 264. In addition, a one-way screw 266 connected to the output end of the driving component 212 rotates in the second screw hole 265 on the block 264, and at the same time, the bottom end of the block 264 is connected to the bottom surface of the inner cavity of the square groove 263 through a spring 267. At this time, the one-way screw 266 can be driven to rotate through the driving component 212, so that the block 264 can be driven to move upward through the second screw hole 265, and then under the pull of the spring 267, the locking tongue 262 can be synchronously driven to move upward, so that the bottom end of the locking tongue 262 can be raised above the serrated block 29, so that the locking tongue 262 releases the limit on the moving block 251, and then by driving the forward and reverse thread screws 24 to run in the opposite direction, the moving block 251 can be driven to move to the middle, so that the lifting mechanism 3 can be folded, which is convenient for the hydraulic actuator to descend.

[0034] Through the pressure-resistant sealing box 2121 and the pressure-resistant sealing cover 2122 in the driving component 212, the forward and reverse motors can be installed and protected, and through the pressure-resistant shaft seal 2123, the output shaft of the forward and reverse motors can be extended out of the pressure-resistant sealing box 2121, and the hydraulic oil can be prevented from entering the pressure-resistant sealing box 2121. The output shaft on the forward and reverse motors can be connected to the corresponding forward and reverse screws 24 or one-way screws 266 through the coupling 2124, so as to drive the forward and reverse screws 24 or one-way screws 266 to operate. Through the stabilizing seat 2125, the pressure-resistant sealing box 2121 can be fixed in a specified position, thereby improving the stability of the use of the pressure-resistant sealing box 2121. Through the junction box 2126, an external control device can be connected to control the operation of each forward and reverse motor.

[0035] Through the support bar 2131 in the anti-fall component 213, it can be inserted into the inner cavity of the guide hole 256, and can be installed on the sleeve 2132 through the fourth connecting bolt 2137. And through the third connecting bolt 2134, the sleeve 2132 can be fixed on the support plate 21, thereby improving the stability of the support bar 2131. Since the top surface of the support bar 2131 is rollingly connected to the roller 259 on the second connecting bolt 258, the support bar 2131 can provide certain support to the moving block 251, thereby improving the stability of the moving block 251.

[0036] Through the positioning plate 41 in the positioning mechanism 4, it can be installed on the bottom surface of the inner cavity of the hydraulic cylinder body through two supporting legs 42, and can provide opening space for two second card grooves 43 and multiple third internal thread grooves 44, and through the cooperation of the second card grooves 43 and the third internal thread grooves 44, one end of the lifting mechanism 3 can be installed and fixed, thereby providing stable support for the lifting mechanism 3.

[0037] The first double-ear fixing seat 32 in the lifting mechanism 3 can be inserted into the inner cavity of the first card slot 14 or the second card slot 43, and can be installed on the first internal thread groove 15 or the third internal thread groove 44 through the mounting plate 33 and the mounting screw 34, so that the first double-ear fixing seat 32 can be fixed on the top plate 11 or the positioning plate 41, and the arm 31 can also be installed at the same time. Since the second double-ear fixing seat 35 is installed at the other end of the arm 31, and the bottom end of the second double-ear fixing seat 35 is inserted into the slot 253 on the moving block 251 through the insert block 36, and the first connecting bolt 255 passes through the sixth through hole 37 on the insert block 36, the first connecting bolt 2 55, so that the plug block 36 can be stably and firmly installed on the moving block 251, thereby ensuring the stability of the connection between the second double-ear fixing seat 35 and the moving block 251, and through the movement of the moving block 251, the support arm 31 can be supported under the connection of the first double-ear fixing seat 32, the support arm 31 and the second double-ear fixing seat 35. Since the inner cavity of the first double-ear fixing seat 32 and the second double-ear fixing seat 35 and the two ends of the support arm 31 are provided with arc-shaped blocks 38, the arc-shaped blocks 38 can play a role in stably transmitting the supporting force of the support arm 31 on the first double-ear fixing seat 32 and the second double-ear fixing seat 35.
