Description
Technical Field
The utility model belongs to the technical field of the speed reducer of the tension leveler is dismantled, concretely relates to novel speed reducer extracting tool of tension leveler.
Background
At present, the speed reducer needs to be disassembled in the maintenance process of a withdrawal and straightening machine of a continuous casting machine of a steel plant, the speed reducer needs to be disassembled by two hydraulic jacks and four persons in a matching way at ordinary times, the disassembly is difficult, and the labor and the time are wasted due to cooperation of multiple persons.
The speed reducer is stressed unevenly and is clamped on an output shaft because the supporting position of the jack and the jacking speeds of the two hydraulic jacks are inconsistent, and the speed reducer is difficult to disassemble. And every time the hydraulic jack needs to be carried for dismounting, the hydraulic jack needs to be located and supported, and the process is complicated.
Therefore, a novel withdrawal and straightening unit speed reducer disassembling tool is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel withdrawal and straightening machine speed reducer extracting tool.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel withdrawal and straightening machine speed reducer extracting tool, includes the screw thread ejector pin, the button head nut is installed to the tip of the first end of screw thread ejector pin, and the hand wheel is installed to the tip of the second end of screw thread ejector pin, and the mid-mounting of screw thread ejector pin has the fixed cardboard of cross, all is equipped with the recess around the fixed cardboard of cross for fix on the speed reducer casing.
Specifically, a nut is welded at the central hole of the cross-shaped fixing clamping plate, so that the cross-shaped fixing clamping plate is arranged on the threaded ejector rod.
Specifically, the end part of the second end of the threaded ejector rod is welded with a nut, so that a hand wheel is clamped on the nut and provided with a fan-shaped gripper, and the speed reducer is ejected out of the output shaft by rotating the hand wheel.
The utility model discloses following beneficial effect has:
1) The tool has simple structure and strong practicability; the assembly and disassembly are simple, and all wearing parts can be simply replaced;
2) The speed reducer is stably disassembled, so that the speed reducer and the shaft are kept horizontal without blockage, and time and labor are saved;
3) The contact surface between the round head ejector rod nut and the shaft center is small in friction force.

FIG. 2 is a schematic structural view of a cross fixing clip plate.
Fig. 3 is a structural schematic diagram of the hand wheel.
In the figure: 1-a round head nut; 2-a threaded mandril; 3-a cross fixing clamping plate; 4-a nut; 5-hand wheel.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-3, a novel withdrawal and straightening unit speed reducer dismounting tool comprises a threaded ejector rod 2, a round-head nut 1 is installed at the end part of the first end of the threaded ejector rod 2, a hand wheel 5 is installed at the end part of the second end of the threaded ejector rod 2, a cross-shaped fixing clamping plate 3 is installed in the middle of the threaded ejector rod 2, and grooves are formed in the periphery of the cross-shaped fixing clamping plate 3 and used for being fixed on a speed reducer shell.
The central hole of the cross-shaped fixing clamping plate 3 is welded with a nut, so that the cross-shaped fixing clamping plate 3 is arranged on the threaded ejector rod 2.
The end part of the second end of the threaded ejector rod 2 is welded with a nut 4, so that a hand wheel 5 is clamped on the nut 4, the hand wheel 5 is provided with a fan-shaped gripper, and an output shaft of the speed reducer is ejected out by rotating the hand wheel 5.
The utility model discloses a use method: the round-head nut 1 is pushed against the output shaft, the cross-shaped fixing clamping plate 2 is fixed on the speed reducer through the groove of the cross-shaped fixing clamping plate 2 by using m5 multiplied by 10 bolts, the hand wheel 5 is clamped on the nut 4, the hand wheel 5 is rotated to drive the threaded ejector rod 2, and the speed reducer is ejected out of the output shaft.
The utility model discloses a simple structure practicality is stronger, can keep speed reducer and output shaft level, consequently can not appear blocking, contacts with round-head nut 1 and output shaft center during the top output shaft, and the contact surface has reduced frictional force, utilizes hand wheel 5 to drive screw ejector pin 2 simultaneously and rotates, more save time, and save the manual work.
The utility model discloses not be limited to above-mentioned embodiment, anybody should learn the structural change who makes under the teaching of the utility model, all with the utility model discloses have the same or close technical scheme, all fall into the utility model discloses an within the protection scope.
The technology, shape and construction parts which are not described in detail in the present invention are all known technology.
