Description

Technical Field

[0001] The utility model relates to the technical field of gear grabbing and lifting equipment, in particular to a lifting equipment which is convenient for grabbing gears. Background Art

[0002] Gears are a basic part of transmission machinery. According to the use environment, gears are divided into high-speed gears and low-speed gears, etc. In the production and manufacturing process of gears, multiple processes are required, from pre-heating to post-heating, after blank initial turning, gear making, heat treatment, post-heat turning and grinding, and post-heat tooth surface finishing, etc., so that the gears need to be processed in different positions and machine tools. Some existing large disc gear materials are heavy and cannot be moved by hand. They need to be hoisted and moved by electric hoists. During the gear making and grinding processes, the existing disc gears are generally fixed by hydraulic clamps to expand the inner hole, and the upper end is fixed by a movable gland. After the processing is completed, the gear is fixed by a manual clamp, and then it is moved upward by the electric hoist. Due to the interference of the gland, the gear needs to be moved horizontally by hand. There is a risk of gear falling during operation, which may cause personal injury to the operator. In addition, the internal space of the large gear machine tool is large. The manual clamp requires the staff to lean into the machine tool to operate, which also has certain safety hazards. For this reason, we propose a lifting device that is convenient for gear grabbing. Utility Model Content

[0013] Beneficial Effects

[0014] The utility model provides a lifting device that is convenient for grabbing gears. It has the following beneficial effects:

[0015] (1) The lifting equipment that facilitates the grasping of gears is provided with an auxiliary module. The electric hoist pulls the mounting frame upward to a certain distance. The staff holds the handle to stabilize the matching plate. The matching plate can be used to stabilize the mounting frame, thereby preventing the gears from shaking and falling. The control device is manually used to control the electric push rod to pull the drive motor to move on the side of the matching plate, so that the mounting frame as a whole drives the gear to move horizontally and the electric hoist lifts and holds the mounting frame, thereby guiding the gear to be placed in a suitable position. The control device controls the drive motor to rotate in the opposite direction to loosen the gear, thereby maintaining a certain distance between the staff and the clamped gear. The electric control of the horizontal movement of the gear is more labor-saving, which facilitates the lifting of the gear grasping and ensures the safety of the gear grasping.

[0016] (2) The lifting device that facilitates the grasping of gears is provided with a clamping module. The mounting frame moves to the upper side of the gear, and the driving motor drives the constraint plate to rotate. The constraint plate can constrain the constraint block to slide inside the constraint groove. The constraint plate constrains the constraint block to slide on the side of the mounting frame so that the connecting rod approaches the side of the gear. The movable plate squeezes the side of the gear and slides into the position inside the movable groove. The movable plate squeezes the detection block in the connecting groove and slides out to a position close to the side of the detection plate. The detection plate detects the connection groove and feeds back a signal to the control device, so that the control device controls the drive motor to stop driving and completes the clamping of the gear. In this way, the staff only needs to observe the position on the side of the machine tool, and then automatically clamp the gear, which facilitates the clamping operation and reduces the risk of human operation.
