DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 3The utility model provides a technical solution: a rotary mechanism lifting device, comprising a base plate 2, a frame 1 is installed on one side of the top of the base plate 2, a cavity is provided in the frame 1, a lifting mechanism is provided in the top of the cavity, a support arm 17 is horizontally connected to one side of the lifting mechanism, and the other end of the support arm 17 extends out of the frame 1 from an adjustment port 23 opened on the side of the frame 1.

[0028] A mounting cylinder 7 is installed vertically downward at the other end of the support arm 17, and a support cylinder 6 is coaxially and rotatably installed (specifically, bearing-mounted) inside the mounting cylinder 7, so that the support cylinder 6 can rotate freely, and both ends of the support cylinder 6 extend to the outside of the mounting cylinder 7;

[0029] A lifting shaft 11 is slidably inserted in the installation tube 7, and both ends of the lifting shaft 11 are located outside the support tube 6. The bottom of the lifting shaft 11 is connected to the wrench 4 through the universal joint 5. The top of the lifting shaft 11 is rotatably installed (specifically, the bearing is installed) in the connecting seat 14. The top of the connecting seat 14 is coaxially installed with a lifting hydraulic cylinder 15. The lifting hydraulic cylinder 15 is installed in the top of the L-shaped bracket 16, and the bottom of the L-shaped bracket 16 is connected to the top surface of the support arm 17.

[0030] In order to prevent the lifting hydraulic cylinder 15 from rotating, Figure 1 As shown, a mounting seat 29 is connected to one side of the connecting seat 14, and a second guide shaft 28 is vertically connected to the top of the mounting seat 29. The second guide shaft 28 slides through the top of the L-shaped bracket 16. The second guide shaft 28 can not only stabilize the movement of the connecting seat 14, but also prevent the connecting seat 14 from rotating with the lifting shaft 11.

[0031] Specifically, when the utility model is in use, the lifting mechanism drives the support arm 17 to move up and down, and the lifting hydraulic cylinder 15 can drive the lifting shaft 11 to move downward along the support tube 6. However, in order to prevent the lifting shaft 11 from rotating, such as Figure 1 As shown, a key groove 13 parallel to the axis of the lifting shaft 11 is provided on the surface, and a flat key block 9 placed in the key groove 13 is provided on the inner wall of the support tube 6. Due to the cooperation between the flat key block and the key groove, the lifting shaft 11 can only move linearly up and down, but cannot rotate.

[0032] The top of the support tube 6 is also connected to a driving mechanism for rotating it. The driving mechanism is arranged on the support tube 6. When the support tube 6 rotates, the lifting shaft 11 rotates with the support tube 6 due to the cooperation of the flat key block and the key slot, thereby allowing the wrench 4 at the bottom of the lifting shaft to rotate.

[0033] Further, such as Figure 1As shown, an electric control cabinet 19 is installed on one side of the top of the frame 1. A controller is arranged in the electric control cabinet 19. The controller is a PLC logic controller or a control main board or a host. The controller is respectively connected to the driving mechanism, the lifting mechanism and the lifting hydraulic cylinder 15. An operation button connected to the controller is also arranged on the surface of the electric control cabinet 19. The operation buttons respectively include buttons for controlling the driving mechanism, the lifting mechanism and the lifting hydraulic cylinder 15.

[0034] Further, such as Figure 2 As shown, the driving mechanism includes a driving motor 12 arranged between the L-shaped bracket 16 and the lifting shaft 11, the driving motor 12 is connected to the controller, the bottom of the driving motor 12 is connected to a reducer 20, and the rotating shaft of the driving motor 12 is connected to the reducer input shaft; the reducer 20 is installed on the top of the U-shaped frame 21, the U-shaped frame 21 is opened downward, the bottoms of both ends of the U-shaped frame 21 are connected to the support seats 22, and the two support seats 22 are respectively connected to the top sides of the support arm 17;

[0035] The output shaft of the reducer 20 extends to the inside of the U-shaped frame 21. A driving gear 10 is coaxially provided on the output shaft of the reducer 20 and the top of the support tube 6. The two driving gears 10 are meshed with each other. In actual use, the diameter of the gear connected to the bottom of the reducer is smaller than the diameter of the gear connected to the top of the support tube, which can increase the output torque. In the utility model, after the driving motor is decelerated by the reducer, the power is transmitted to the support tube 6 through gear meshing, causing the support tube 6 to rotate.

[0036] Further, such as Figure 2 As shown, the lifting mechanism includes two connecting plates 32 arranged in the top of the cavity of the frame 1, a certain distance is set between the two connecting plates 32, a ball screw 8 is arranged between the two connecting plates 32, both ends of the ball screw 8 are respectively connected to the connecting plates 32 for rotation, a moving seat 31 is connected to the ball screw 8 through a nut, and the moving seat 31 is connected to the support arm 17;

[0037] The bottom of the ball screw 8 is connected to the adjusting motor 34, the adjusting motor 34 is connected to the controller, the adjusting motor 34 is mounted on the motor mounting plate 35, and the motor mounting plate 35 is fixed in the cavity;

[0038] A guide seat 33 is connected to both sides of the moving seat 31, and a third guide shaft 30 is provided through the ends of the guide seat 33, and both ends of the third guide shaft 30 are respectively connected to the connecting plate 32. The third guide shaft 30 mainly guides the moving seat 31, so that the moving seat 31 can move up and down more stably. In the present utility model, the moving seat 31 is driven up and down by adjusting the motor 34, thereby driving the wrench 4 to move up and down.

[0039] Furthermore, the controller is also connected to a clamping mechanism, such as Figure 1 As shown, the clamping mechanism includes a first connecting arm 24 disposed at the middle position of both sides of the frame 1, and the other end of the first connecting arm 24 is vertically connected to a second connecting arm 25, and the second connecting arm 25 is located above the bottom plate 2;

[0040] The ends of the second connecting arms 25 are installed with clamping hydraulic cylinders 27 which are arranged opposite to each other. The clamping hydraulic cylinders 27 are connected to the controller. The ends of the clamping hydraulic cylinders 27 are connected with arc-shaped clamping plates 3. The outer side surfaces of each arc-shaped clamping plate 3 are connected with a first guide shaft 26 which is arranged through the second connecting arm 25. In actual use, the steel cylinder is placed on the base plate 2, and then the clamping hydraulic cylinders 27 are controlled to drive the arc-shaped clamping plates 3 to clamp and fix the steel cylinder sideways. The arc-shaped clamping plates 3 can also position the steel cylinder so that the clamped steel cylinder is directly located below the wrench.

[0041] Finally, when the utility model is used, the steel cylinder is placed on the bottom plate 2, and then clamped and fixed by the arc-shaped clamping plate 3, and the lifting mechanism is controlled to drive the wrench to descend. When the wrench descends to a preset position, the wrench 4 can be held by hand. Since the top of the wrench is a universal joint, the wrench can be easily aligned with the valve on the top of the steel cylinder when held manually;

[0042] like Figure 3 As shown, the wrench 4 includes arc-shaped curved portions 36 arranged on both sides thereof, the arc-shaped curved portions 36 are all protruding outward, and the bottom of the arc-shaped curved portions 36 is gathered inward at the center line of the lifting shaft 11, and a rectangular clamping portion 18 is connected to the bottom of the arc-shaped curved portions 36. The cavity formed between the two arc-shaped curved portions 36 is to prevent the knob on the top of the valve, and the rectangular clamping portion 18 is clamped on both sides of the valve. When the wrench is rotated, the distance between the two rectangular clamping portions 18 matches the shape of the valve, so the rectangular clamping portion 18 drives the valve to rotate, and the valve can be quickly removed or installed from the cylinder.
