[0020] 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.

[0021] See also Figure 1-3 The utility model provides an implementation scheme: In the process of electromechanical maintenance, there are many situations in which lifting devices are used. At present, when the lifting devices use hydraulic power, the hydraulic locking will be unstable due to the placement of workpieces and other reasons. In extreme cases, overload and other problems may cause leakage or damage to the hydraulic device.

[0022] Based on the above problems, the present application discloses an adaptive hydraulic power maintenance lifting device, which uses a mobile base 1 as the moving and supporting basis of the equipment, and the mobile base 1 is a rectangular plate, and at least one pair of lifting guide rails 2 is arranged on the mobile base 1, and a pair of lifting sliders 3 are arranged on both sides of the pair of lifting guide rails 2. The pair of lifting sliders 3 cooperate with the pair of lifting guide rails 2, and a support plate 4 is connected to the top of the pair of lifting sliders 3. Through the mutual limitation of the pair of lifting guide rails 2 and the pair of lifting sliders 3, the pair of lifting sliders 3 can drive the support plate 4 to move up and down, and stably adjust the position of the support plate 4;

[0023] The power for adjustment is a pair of hydraulic lifting cylinders 5. A pair of hydraulic lifting cylinders 5 are correspondingly arranged on the inner side of the pair of lifting slide blocks 3. The pair of hydraulic lifting cylinders 5 are connected to the top of the pair of lifting slide blocks 3. Through the extension and retraction of the pair of hydraulic lifting cylinders 5, the pair of lifting slide blocks 3 can be moved up and down, thereby driving the support plate 4 to move up and down.

[0024] Furthermore, in order to achieve the self-adaptation problem of the hydraulic device, a toothed belt groove 6 is provided on one side of one of the lifting sliders 3, and a mounting groove 7 is provided on the lifting guide rail 2 corresponding to the lifting slider 3. A detection seat 8 is mounted on the mounting groove 7, and a detection gear 9 is movably mounted on the detection seat 8 to mesh with the toothed belt groove 6. An encoder 10 is connected to the central axis of the detection gear 9, which is connected to one side of the mounting groove 7 through the detection seat 8, so that the detection gear 9 on the detection seat 8 is meshed with the toothed belt groove 6 through the mounting groove 7. During the lifting process of the lifting slider 3, as the toothed belt groove 6 moves, the toothed belt groove 6 drives the detection gear 9 to rotate, and then the detection gear 9 drives the encoder 10 to rotate. The lifting position of the lifting slider 3 is detected by the rotation of the encoder 10. A limit card plate 11 is provided on the inner side of the lifting slider 3. The limit card plate 11 is connected to the hydraulic lifting cylinder 5 to adjust the lifting slider 3;

[0025] When the encoder 10 detects the lifting position, the encoder 10 controls the synchronous control motor 13 to rotate, and then the synchronous control motor 13 drives the control threaded tube 12 to rotate, and then the control threaded tube 12 is meshed with the control screw 14, so that the control screw 14 drives the supporting seat 15 to move linearly, and then the supporting seat 15 is a short distance away from the limit card plate 11, so as to achieve the supporting effect. At the same time, the reverse thrust of the threaded structure is used to keep the protection of the limit card plate 11 to avoid the rapid sinking of the support plate 4, so as to achieve the self-adaptation of the control height. When the supported weight is heavy, the descent of the hydraulic lifting cylinder 5 will drive the encoder 10 to slide back, and then the hydraulic oil is continuously pushed into the hydraulic lifting cylinder 5 through the hydraulic pump station, so that the hydraulic lifting cylinder 5 pushes the support plate 4 to maintain the height of the support plate 4.

[0026] As a preferred solution, further, the support plate 4 is connected to the ends of a pair of lifting slide blocks 3 by bolts, and a protective frame 16 is provided on the support plate 4 to protect the upper maintenance personnel.

[0027] As a preferred solution, further, the position of the supporting seat 15 corresponds to the limit clamping plate 11, and the telescopic ends of a pair of hydraulic lifting cylinders 5 are fixedly connected to a pair of limit clamping plates 11. When the position of the limit clamping plate 11 is height-adjusted by the hydraulic lifting cylinders 5, it can play a supporting role for the lifting slider 3.

[0028] As a preferred solution, further, the encoder 10 is installed on the detection base 8 and is electrically connected to the synchronous control motor 13 , and the synchronous control motor 13 is controlled by the detection signal of the encoder 10 .

[0029] As a preferred solution, further, a pair of auxiliary telescopic rods 17 are symmetrically arranged on both sides of the control screw 14, and the bottom ends of the pair of auxiliary telescopic rods 17 are connected to the movable base 1 and the top ends are connected to the supporting seat 15, so as to stabilize the supporting seat 15 and play a role in sharing the bearing capacity.

[0030] From the above, it can be generally known that the adaptive hydraulic power maintenance lifting device adopts a hydraulic cylinder as the power for adjustment. An encoder 10 is arranged on the outside of the lifting slider for accurate detection of the lifting position. A lifting screw rod is configured for stability and protection. According to the result of accurate detection, the hydraulic cylinder is accurately adjusted, and the lifting slider 3 is supported by a synchronous control motor 13 to avoid sudden and rapid descent of the maintenance device, which may cause equipment damage and personal injury.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
