DETAILED DESCRIPTION

[0022] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0023] Embodiment 1:

[0024] refer to Figure 1The embodiment of the present invention discloses a wireless hydraulic lifting control device for a brick machine platform, including a lifting platform 1, a rotating platform 2, a hydraulic cylinder 3, a valve block 4, an oil pump 5, an oil storage tank 6 and a wireless control terminal 7. The lifting platform 1 is fixedly installed on the top of the telescopic rod of the hydraulic cylinder 3, and the lifting platform 1 is driven to move up and down by the hydraulic cylinder 3. The rotating platform 2 is rotatably installed on the lifting platform 1 through a plane bearing 11, so that the rotating platform 2 can rotate around the vertical axis relative to the lifting platform 1. The processed blocks 8 are stacked on the pad 81 and placed on the rotating platform 2 together with the pad 81. The lifting platform 1 is driven to move up and down by the hydraulic cylinder 3, and the rotating platform 2 and the blocks 8 are moved up and down synchronously, so that the blocks 8 are lifted or lowered to the required height, and then the rotating platform 2 is driven to rotate by the motor 25 fixedly installed at the bottom of the lifting platform 1, so as to adjust the direction of the blocks 8, so that the blocks 8 and the pad 81 can be discharged together.

[0025] In this embodiment, preferably, a row of rollers 21 are rotatably installed on the rotating table 2, and the top ends of the rollers 21 are higher than the upper end surface of the rotating table 2. The pads 81 and the building blocks 8 are carried on the surfaces of multiple rollers 21. When discharging, the building blocks 8 can be pushed along the vertical direction of the rollers 21 to complete the discharging, avoiding the trouble caused by hoisting or other transportation methods.

[0026] In this embodiment, preferably, a side plate 22 is fixedly installed on one side of the rotating table 2, a cylinder 23 is fixedly installed on the outer side of the side plate 22, a push plate 24 is fixedly installed on the telescopic end of the cylinder 23, and the push plate 24 is linearly telescopic in a direction perpendicular to the roller shaft 21, thereby completing the pushing and discharging of the building blocks 8.

[0027] In order to accurately control the lifting height of the hydraulic cylinder 3, the present embodiment is provided with a valve block 4, on which a first oil outlet 4a, a second oil outlet 4b, an oil return port 4c, and an oil inlet 4d are provided. The first oil outlet 4a is connected to the rodless chamber 32 of the hydraulic cylinder 3, the second oil outlet 4b is connected to the rod chamber 31 of the hydraulic cylinder 3, the oil return port 4c is directly connected to the oil storage tank 6, and the oil inlet 4d is connected to the oil pump 5 and the oil storage tank 6 in sequence. Among them, the oil pump 5 is wirelessly connected to the wireless control terminal 7 to realize the start and stop operation of the oil pump 5 controlled by the wireless control terminal 7, thereby reducing the wiring at the processing site and the frequency of workers' movement, thereby reducing safety hazards, improving safety, and ensuring safe production.

[0028] See also Figure 2In this embodiment, specifically, the valve block 4 has a check valve 41, a balancing valve 42, a first electromagnetic reversing valve 43, a one-way throttle valve 44, a hydraulically controlled one-way valve 45, a proportional directional valve 46, a second electromagnetic reversing valve 47, and a relief valve 48. The check valve 41, the proportional directional valve 46, the balancing valve 42, the first electromagnetic reversing valve 43 and the one-way throttle valve 44 are sequentially connected between the oil inlet 4d and the second oil outlet 4b. The first electromagnetic reversing valve 43 is a two-position two-way electromagnetic valve, and the one-way throttle valve 44 is used to adjust the hydraulic oil flow in one direction. A proportional directional valve 46 and a hydraulically controlled one-way valve 45 are arranged in sequence to connect the oil return port 4c and the first outlet oil. The valve core position inside the proportional directional valve 46 is used to switch the oil flow direction, and the pressure oil flow rate can be adjusted to the required oil flow rate that meets the rise or fall of the telescopic rod of the hydraulic cylinder 3, so that the hydraulic cylinder 3 is used to control the lifting platform 1 to rise or fall accurately, so that the lifting height of the building block 8 can be adjusted more accurately.

[0029] In order to ensure that the hydraulic cylinder 3 has a stable pressure, a solenoid overflow valve 48 capable of controlling the pressure is provided between the oil inlet 4d and the oil return port 4c. The solenoid overflow valve 48 is formed by connecting the second solenoid reversing valve 47 and the overflow valve 48 in parallel. The second solenoid reversing valve 47 is a two-position four-way solenoid valve. The overflow valve 48 sets the pressure of the entire hydraulic system to prevent the oil pump 5 and the cylinder body of the hydraulic cylinder 3 from being damaged by excessive pressure.

[0030] In order to realize remote lifting and lowering adjustment of the hydraulic cylinder 3, the first electromagnetic reversing valve 43, the second electromagnetic reversing valve 47 and the proportional directional valve 46 are all wirelessly connected to the wireless control terminal 7, so that the first electromagnetic reversing valve 43, the second electromagnetic reversing valve 47 and the proportional directional valve 46 can be remotely switched through the wireless control terminal 7, thereby adjusting the oil flow direction inside the valve block 4 to realize the remote and precise lifting control of the hydraulic cylinder 3.

[0031] In this embodiment, the lifting and lowering control process of the hydraulic cylinder 3 is specifically as follows:

[0032] Combination Figure 3 , Figure 3 It is a schematic diagram of the lifting state of the telescopic rod of the hydraulic cylinder 3. The oil in the oil storage tank 6 enters the valve block 4 from the oil inlet 4d through the oil pump 5, enters the proportional directional valve 46 through the check valve, and is adjusted by the valve core displacement of the proportional directional valve 46, and the lifting oil injection amount of the hydraulic cylinder 3 is adjusted, so that the oil passes through the balance valve 42, the first electromagnetic reversing valve 43, and the one-way throttle valve 44 in sequence and enters the rodless chamber 32 of the hydraulic cylinder 3, so that the telescopic rod is lifted upward, and the oil in the rod chamber 31 is discharged through the first oil outlet 4a, flows through the hydraulically controlled one-way valve 45, and then passes through the proportional directional valve 46 and is discharged from the oil return port 4c, and flows back to the oil storage tank 6, thereby completing the accurate lifting operation of the hydraulic cylinder 3.

[0033] Combination Figure 4 , Figure 4 It is a schematic diagram of the telescopic rod descending state of the hydraulic cylinder 3. The oil in the oil storage tank 6 enters the valve block 4 from the oil inlet 4d through the oil pump 5, enters the proportional directional valve 46 through the check valve, and is adjusted by the valve core displacement of the proportional directional valve 46. The oil injection amount for the hydraulic cylinder 3 to descend is also adjusted so that the oil enters the rod chamber 31 of the hydraulic cylinder 3 after passing through the hydraulically controlled one-way valve 45 to cause the telescopic rod to move downward. The oil in the rodless chamber 32 is discharged through the second oil outlet 4b, and flows through the one-way throttle valve 44, the first solenoid reversing valve 43, the balance valve 42, and the proportional directional valve 46 in sequence, and then is discharged from the oil return port 4c and flows back to the oil storage tank 6, thereby completing the accurate descending operation of the hydraulic cylinder 3.
