[0002] A hoist is a light and small lifting device that winds a wire rope or chain around a drum to lift or tow heavy objects. It is also called a winch. Hoists are divided into manual hoists and electric hoists, etc. Now, electric hoists are mainly used. It can be used alone or as a component in machinery such as lifting and road construction and mine hoisting.

[0034] A hydraulic telescopic cylinder seven 58 is arranged on the side of the connecting bar 50 away from the turntable 6. A fixing rod 57 is fixedly connected to the upper side of the connecting block two 48. One end of the fixing rod 57 away from the connecting block two 48 is hinged to the fixed end of the hydraulic telescopic cylinder seven 58. The upper part of the side of the connecting bar 50 facing the center of the circular guide rail two 41 is hinged to the output end of the hydraulic telescopic cylinder seven 58; The triangular structure of the hydraulic telescopic cylinder seven 58, the fixing rod 57 and the connecting bar 50 strengthens the stability of the pressure of the pressing block 56 on the fitting by the hydraulic telescopic cylinder six 55.

[0035] One end of the fixed rod 57 away from the second connecting block 48 is fixedly connected with a laser scanning sensor 59. The laser scanning sensor 59 is a conventional existing technology. By irradiating a laser at the target object and receiving the reflected light and the changes after refraction through a photosensitive element, the overall contour of the hoist accessories is scanned in a non-contact manner; The laser scanning sensor 59 is signal-connected to a processor. The processor calculates the outer contour of the hoist accessories after scanning by the laser scanning sensor 59 and constructs a three-dimensional model, and marks the specific information to be processed of the hoist accessories, including but not limited to: the position coordinates of the accessories processing, the processing method, etc.

[0036] In this embodiment, the accessory to be processed is hoisted and placed on the support plate composed of the central disk 12 and the annular support group 15. In the initial state, the fifth hydraulic telescopic cylinder 47 is in the extended state. During the hoisting process, the outer contour of the accessory is scanned by the laser scanning sensor 59, and a three-dimensional model is constructed by the processor; The processor calculates the center point of the hoist accessories, and controls the movement of the hoist accessories through the hoisting tool, so that its center point coincides with the center point of the central disk 12. Then, according to the outer contour shape of the side of the accessory close to the turntable 6, the corresponding support blocks 16 are controlled to rise or fall. Without damaging and affecting the processing of the accessories, the maximum support area is provided for the accessories, so as to increase the stability of the support for the accessories; Exemplarily, when drilling is required for the accessory processing, the relevant support blocks 16 at the corresponding position of the accessory are controlled to descend, leaving a certain gap to prevent damage to the drill bit during drilling Subsequently, the hoist accessories are placed on the support plate, and then the pump body 20 is started, and the air valve of the corresponding air hole 18 is opened, and the hoist accessories are negatively adsorbed through the air hole 18.

[0037] Then, the accessory is positioned and clamped. Control a corresponding number of the first sliding seats 23 to slide to the corresponding positions. The clamped positions should be the positions on the accessory that are not processed, not weak, without holes and without grooves, so as to avoid damaging and deforming the accessory during the positioning and clamping process.

[0038] Subsequently, the angle of the clamping block 38 is effectively adjusted according to the shape of the surface of the accessory clamped by the clamping assembly 28. Exemplarily, when the surface of the accessory clamped by the clamping assembly 28 is a plane, the clamping block 38 clamps at an angle perpendicular to the plane.

[0039] During the process of the clamping block 38 clamping the accessory, the pressure sensor I monitors the pressure of the clamping block 38 clamping the accessory to prevent overpressure clamping of the accessory and causing damage to the accessory.

[0040] After the clamping block 38 finishes clamping the fitting, the air valve of the air pipe controlling the corresponding air hole 18 is opened, so that the air hole 18 adsorbs the suction plate 39, thereby improving the clamping stability of the clamping block 38 on the fitting during the processing.

[0041] Then, control the output end of the hydraulic telescopic cylinder five 47 to retract, so that the circular guide rail two 41 descends to a position at a corresponding height, control the corresponding number of sliding seats three 42 to move to corresponding positions, and at the same time, respectively control the driving motor five 53 to rotate. The rack 51 drives the connecting bar 50 to move towards the center side of the circular guide rail two 41. According to the shape of the fitting, control the stroke of each connecting bar 50 to move. Subsequently, control the output end of the hydraulic telescopic cylinder six 55 to extend, so that the pressing block 56 descends to complete the positioning and clamping of the fitting in the vertical direction. During the descent of the pressing block 56, control the pressure of the pressing block 56 on the fitting through the pressure sensor one to prevent the pressing block 56 from clamping the fitting with excessive pressure.

[0042] After the positioning and clamping are completed, control the lifting of the support table 3 and the rotation of the turntable 6 to rotate the fitting, and cooperate with the processing equipment to process the fitting.
