Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically to an automatic tilting device for a walking speed reducer. Background Technology

[0002] After assembly, the travel reducer faces downwards with the large flange side down and requires gear oil. Before entering the painting line, it needs to be flipped up so the large flange side faces upwards. Without specialized tools, the operator must flip it by hand. The workpiece is heavy, posing a safety hazard, and the work is physically demanding, easily leading to hand and back injuries.

[0003] Automatic flipping robots cost over 200,000 yuan, are expensive, have limitations in use due to the influence of the work site and the shape of the workpiece, require charging, and have high technical requirements for operators, making them unsuitable for use in our company.

[0004] Therefore, an automatic tilting device for a walking speed reducer is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic tilting device for a walking speed reducer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic tilting device for a walking speed reducer, comprising two connecting plates, which are arranged crosswise and rotatably connected by bolts. A connecting seat is installed at the bottom end of the two connecting plates, and a rotating shaft is rotatably connected inside the connecting seat. A pawl for locking the speed reducer is installed at one end of the rotating shaft, and a handle-shaped knob plunger positioning pin for limiting the position of the rotating shaft is installed on the connecting seat.

[0007] Preferably, the rotating shaft has a limiting hole that cooperates with the positioning pin of the handle-type knob plunger.

[0008] Preferably, a bearing is installed inside the connecting seat, and the rotating shaft is installed inside the bearing.

[0009] Preferably, both connecting plates are equipped with bow-shaped shackles at their top ends.

[0010] Preferably, springs are symmetrically installed between the two connecting plates.

[0011] Preferably, the rotating shaft is made of 45# round steel, and the connecting seat, the claw, and the two connecting plates are made of Q235 steel plate.

[0012] Preferably, the claw has a U-shaped groove for locking the reducer bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the device has two modes, ordinary lifting mode and flipping mode, and the workpiece is clamped by the weight of the object being lifted. It can automatically flip without providing external power, reducing labor intensity, improving safety, and has a simple structure, is easy to operate, and saves costs. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an automatic tilting device for a walking speed reducer, comprising two connecting plates 1, which are arranged crosswise and rotatably connected by bolts. A connecting seat 4 is installed at the bottom of the two connecting plates 1. A rotating shaft 6 is rotatably connected inside the connecting seat 4. A pawl 7 for locking the speed reducer is installed at one end of the rotating shaft 6. A handle-shaped knob plunger positioning pin 5 for limiting the position of the rotating shaft 6 is installed on the connecting seat 4.

[0021] like Figure 2 As shown: The rotating shaft 6 is provided with a limiting hole 8 that cooperates with the handle-type knob plunger positioning pin 5; through the above settings, the handle-type knob plunger positioning pin 5 is a standard part, which can be inserted by rotating the handle to allow the internal pin to extend into the limiting hole 8 and restrict the position of the rotating shaft 6, so that the rotating shaft 6 cannot rotate.

[0022] like Figure 2 As shown: a bearing 9 is installed inside the connecting seat 4, and the rotating shaft 6 is installed inside the bearing 9; with the above settings, the bearing 9 is a deep groove ball bearing, and the bearing 9 is installed inside the connecting seat 4 through the hole with an elastic retaining ring, which makes it easier and faster for the rotating shaft 6 to rotate.

[0023] like Figure 1 As shown: Both connecting plates 1 are equipped with bow-shaped shackles 2 at their top ends; with the above settings, the equipment can be lifted as a whole by means of external hooks cooperating with bow-shaped shackles 2.

[0024] like Figure 1 As shown: Springs 3 are symmetrically installed between the two connecting plates 1; with the above arrangement, the springs 3 bear the weight of the left and right connecting plates 1, so that the user can easily separate the claws 7.

[0025] like Figure 1 As shown: the rotating shaft 6 is machined from No. 45 round steel, and the connecting seat 4, the claw 7 and the two connecting plates 1 are machined from Q235 steel plates.

[0026] like Figure 3 As shown: The chuck 7 has a U-shaped groove for locking the reducer bolts; through the above setting, the U-shaped groove can play a role in positioning and preventing detachment.

[0027] Working principle: The crane uses a lifting device with two hooks to lift the bow-shaped shackle 2. The user separates the two jaws 7, which have U-shaped grooves for positioning, to lock the bolts on the reducer. When the crane rises, the upper opening of the scissor-shaped connecting plate 1 retracts inward, and at the same time, the jaws 7 retract inward, thereby locking the reducer and facilitating the lifting operation.

[0028] When the pin of the handle-type knob plunger positioning pin 5 is inserted into the limit hole 8, this device can be used as a regular lifting tool to lift the reducer onto the tilting platform.

[0029] When the pin of the handle-type knob plunger positioning pin 5 disengages from the inside of the limiting hole 8, the rotating shaft 6 is unrestricted and can rotate freely. As the crane rises, the reducer will automatically flip under its own weight and can then be moved to the designated tray, and so on.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
