Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, and relates to a hook assembly, in particular to a hook assembly for gear suspension conveying. Background Art

[0002] When gears are transported during the processes of machining, cleaning, shot blasting, and heat treatment, in order to avoid tooth surface scratches and defects caused by manual loading and unloading or collisions between gears, corresponding automated conveying lines are generally set up.

[0003] Among them, the above-mentioned conveying line, such as a gear transmission line (application number: CN201721722487.X) disclosed in a Chinese patent, includes a bottom plate, a motor, a bevel gear box, a vertical frame, a transmission shaft, and a transmission rail. The motor, bevel gear box, transmission shaft, and vertical frame are fixed on the floor. The bevel gear box, transmission rail, and transmission shaft are located inside the vertical frame. A transmission chain sprocket is provided on one side of the bevel gear box. A transmission spur gear is provided at the end of the bevel gear box. A driving chain sprocket is provided at the end of the motor. A transmission chain sprocket and a clamping tooth disc are fixed at the upper end of the transmission shaft. The transmission chain sprocket is located above the clamping gear. A transmission spur gear disc is fixed at the lower end of the transmission shaft. The transmission chain sprocket is connected and driven to the driving chain sprocket through a chain. The transmission spur gear and the transmission spur gear disc are meshed with each other. A chain belt meshing with the transmission chain sprocket is provided on the transmission rail. A plurality of hooks are evenly arranged below the chain belt. When the hook rotates into the transmission chain sprocket, it is just clamped in the tooth gaps of the clamping tooth disc.

[0004] In actual products, a guide frame is connected above the hook. Pulleys cooperating with the transmission rail are provided on both sides of the guide frame for the support and guidance of the hook movement. Since there are many sizes and types of gears, and one type of hook can only adapt to some gears, different types of hooks need to be replaced to adapt to different gears during actual use. However, in the above structure, the hook and the guide frame are fixedly connected and not easily disassembled, which is not conducive to hook replacement. Summary of the Utility Model

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Embodiment 1

[0023] like Figure 1 As shown, the hook assembly for gear suspension transportation includes a hook 1 and a strip support 2.

[0024] in,

[0025] The support 2 is made of an elastic material, which may be a plastic material or a stainless steel material, and the support 2 is preferably made of a plastic material to reduce costs. Rollers 3 are installed at both ends of the support 2, and the two rollers 3 are arranged side by side along the length direction of the support 2. In actual products, the rollers 3 are rotatably arranged on the support 2 through a rotating shaft.

[0026] like Figure 2 and Figure 3As shown, the upper end of the hook 1 is a vertically arranged rod body 1a, and a round rod 1b is vertically formed on the top surface of the rod body 1a. The round rod 1b and the rod body 1a are coaxially arranged, and the outer diameter of the round rod 1b is smaller than the outer diameter of the rod body 1a. A circular hole 2a is vertically penetrated on the support 2 for the upper end of the round rod 1b to pass through, and the outer circumference of the round rod 1b is attached to the inner circumference of the circular hole 2a. An opening 2b is vertically provided on one side of the circular hole 2a to enable the round rod 1b to extend into or out of the circular hole 2a, and the ratio of the arc length of the inner circumference of the circular hole 2a to the arc length of the whole circle in which it is located is greater than 3 / 4. A retaining ring 1c is formed on the outer wall of the upper end of the circular rod 1b, and the retaining ring 1c is coaxially arranged with the circular rod 1b. The retaining ring 1c is pressed on the top surface of the support 2, and the outer diameter of the retaining ring 1c is greater than the aperture of the circular hole 2a but less than or equal to the outer diameter of the rod body 1a; the support 2 is also provided with a connection structure that forms a detachable fixed connection between the support 2 and the round rod 1b. In actual products, the outer diameter of the retaining ring 1c is the same as the outer diameter of the rod body 1a, which is convenient for processing.

[0027] During assembly, the round rod 1b is inserted into the round hole 2a through the opening 2b, and the connecting structure is installed to connect the support 2 and the hook 1 together; during disassembly, the connecting structure is first removed, and then the round rod 1b is pulled out of the round hole 2a with the help of the opening 2b. The whole process has fewer steps and has the advantages of convenient and easy disassembly and assembly.

[0028] By setting the outer diameter of the retaining ring 1c larger than the circular hole 2a and the ratio of the arc length of the inner circumference of the circular hole 2a to the arc length of the entire circle in which it is located to be greater than 3 / 4, the hook 1 will not fall directly when the connecting structure falls off, effectively enhancing the safety of gear suspension transportation.

[0029] In this embodiment,

[0030] like Figure 1 and Figure 3 As shown, the connection structure includes protrusions 2c formed on the edges of both sides of the opening 2b, and the protrusions 2c are outside the circular hole 2a. The two protrusions 2c are arranged side by side along the distribution direction of the two rollers 3, and the two protrusions are connected by a horizontally arranged screw 4 so that the circular hole 2a shrinks and hugs the above-mentioned round rod 1b. By screwing in or out the screw 4, the round rod 1b can be detachably connected to the support 2, which has the advantages of being easy and convenient to use. Preferably, both protrusions 2c are horizontally penetrated with threaded holes that cooperate with the screw 4, so that the screw 4 can be more securely positioned, thereby more stably hugging the round rod 1b and strengthening the connection strength between the support 2 and the hook 1.

[0031] To further explain, the top surface of the rod body 1a presses against the bottom surface of the support 2 to increase the contact area between the two, making the connection between the hook 1 and the support 2 more stable. Embodiment 2

[0032] The structure and principle of the second embodiment are basically the same as those of the first embodiment, except that the connection structure includes a retaining ring 1c and a pressure ring screwed onto the round rod 1b, and the pressure ring is tightly pressed against the bottom surface of the support 2.

[0033] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
