Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, specifically to an anti-lifting device. Background Technology

[0002] In the tire manufacturing industry, tooling trolleys are the core transfer equipment at the forming machine's guide station. Tooling trolleys typically have a pressure bar; when in use, workers need to press the pressure bar to pull the goods. When the tooling trolley is not in use, the pressure bar is usually lowered and the trolley is left idle. However, the pressure bar may lift under certain circumstances, such as if a worker accidentally touches it, causing it to rise under pressure. In this situation, the raised pressure bar can easily strike a person, causing a workplace injury.

[0003] The existing method involves installing positioning hooks to attach the pressure bar, which is then locked in place. However, this structure requires workers to frequently manually attach and detach the hooks, which can easily lead to fatigue or oversight during continuous operation. Furthermore, when the hooks are not attached, the pressure bar may accidentally lift, causing component displacement or even mechanical injury. This results in low reliability of the safety measures.

[0004] Therefore, existing technologies need further development. Utility Model Content

Furthermore, the limiting mechanism includes: a limiting rod, with the abutting portion located at one end of the limiting rod; the limiting portion located at the other end of the limiting rod; and a connecting rod connected to the limiting rod, wherein the connecting rod is rotatably connected to the first fixed component.

[0008] Furthermore, the limiting mechanism includes a pin; the pin passes through a first connecting hole of the first fixing component and a second connecting hole of the connecting rod; the pin is connected to a nut, thereby axially locking the limiting rod onto the first fixing component. Furthermore, the anti-lifting device also includes a pressure rod; the pressure rod is connected to the limiting rod; the pressure rod is located on the side of the first fixing component away from the second fixing component. Furthermore, the plane of rotation of the limiting rod is perpendicular to the axis of the pressure rod. Furthermore, when the limiting mechanism is in its natural state, the center of gravity of the pressure rod is located below the axis of the pin.

[0009] Furthermore, the connecting rod is connected to the limiting part; the angle between the extending direction of the connecting rod and the extending direction of the limiting rod is 60°.

Detailed Implementation

[0014] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0015] like Figure 1 , Figure 3As shown, according to an embodiment of the present invention, an anti-lifting device is provided, comprising: a base 1; a first fixing component 2 and a second fixing component 3; both the first fixing component 2 and the second fixing component 3 are connected to the base 1; the first fixing component 2 and the second fixing component 3 are arranged at intervals to form a limiting space 5 for placing a component 4 to be limited between the first fixing component 2 and the second fixing component 3; a limiting mechanism 6, the limiting mechanism 6 being movably connected to the first fixing component 2; the limiting mechanism 6 including an abutting part 7 and a limiting part 8; in a natural state, the abutting part 7 abuts against the base 1 to restrict the movement of the limiting part 8, thereby limiting the component 4 to be limited from moving out of the limiting space 5.

[0016] Specifically, the anti-lifting device includes a base 1, a first fixing component 2, a second fixing component 3, and a limiting mechanism 6. The first fixing component 2 and the second fixing component 3 are fixed to the base 1 at intervals, forming a limiting space 5 to accommodate the component 4 to be limited, such as a tooling clamping rod. The abutting part 7 of the limiting mechanism 6 abuts against the base 1 in its natural state, such as... Figure 1 This allows the limiting part 8 to automatically lock the component 4 to be limited, effectively preventing the pressure bar from being lifted unexpectedly. It solves the safety hazards caused by omissions in manual hook operation and addresses the technical problem of the pressure bar of the tooling car being easily lifted in related technologies.

[0017] In the anti-lifting device of this embodiment, such as Figure 2 As shown, the limiting mechanism 6 is movably arranged, and by moving the limiting mechanism 6, the limiting part 8 avoids the limiting space 5.

[0018] Specifically, the limiting mechanism 6 can rotate around the pin 11, causing the limiting part 8 to disengage from the limiting space 5. This enables quick unlocking, allowing the limiting component 4 to be released with only one hand by operating the pressure lever 13, thus improving operational efficiency.

[0019] like Figure 4 , Figure 6 , Figure 7 As shown, in the anti-lifting device of this embodiment, the limiting mechanism 6 includes a limiting rod 9, an abutting part 7 located at one end of the limiting rod 9, a limiting part 8 located at the other end of the limiting rod 9, and a connecting rod 10 connected to the limiting rod 9. The connecting rod 10 is rotatably connected to the first fixing component 2.

[0020] Specifically, the limiting mechanism 6 consists of a limiting rod 9 and a connecting rod 10. The abutment part 7 and the limiting part 8 are respectively located at both ends of the limiting rod 9, and the connecting rod 10 is rotatably connected to the first fixed component 2 via a pin 11. The split design simplifies manufacturing; the limiting rod 9 can be manufactured separately, and the lever structure of the abutment part 7, such as... Figure 1 Increase the locking force to ensure that the pressure bar does not come out under vibration.

[0021] like Figure 4, Figure 5 , Figure 9 As shown, in the anti-lifting device of this embodiment, the limiting mechanism 6 includes a pin 11; the pin 11 passes through the first connecting hole 21 of the first fixing component 2 and the second connecting hole 101 of the connecting rod 10; the pin 11 is connected to the nut, thereby axially locking the limiting rod 9 onto the first fixing component 2.

[0022] Specifically, the pin 11 passes through the first connecting hole 21 and the second connecting hole 101, and is axially locked by a nut. The pin fit clearance design reduces processing costs, and the nut locking method prevents loosening after long-term use, extending the life of the device. In the anti-lifting device of this embodiment, such as Figure 1 , Figure 8 As shown, the anti-lifting device also includes a pressure rod 13; the pressure rod 13 is connected to the limiting rod 9; the pressure rod 13 is located on the side of the first fixing component 2 away from the second fixing component 3. Specifically, the pressure rod 13 is welded to the outside of the limiting rod 9. During operation, pulling up the pressure rod 13 drives the limiting mechanism 6 to rotate and unlock, thus avoiding the limiting component 4. Figure 2 As shown. The extended lever design provides a force-saving operating fulcrum, and the optimized lever arm length reduces the operating force.

[0023] like Figure 1 , Figure 8 As shown, in the anti-lifting device of this embodiment, the rotation plane of the limiting rod 9 is perpendicular to the axis of the pressure rod 13.

[0024] Specifically, the rotation plane of the limiting rod 9, i.e. the circumferential surface around the pin 11, is perpendicular to the axis of the pressure rod 13. This structure ensures that the downward pressure and upward lifting force are efficiently converted into rotational torque, avoiding mechanism jamming caused by lateral force.

[0025] like Figure 1 As shown, in the anti-lifting device of this embodiment, when the limiting mechanism 6 is in its natural state, the center of gravity of the pressure rod 13 is located below the axis of the pin 11.

[0026] With the above configuration, the center of gravity of the pressure rod 13 is located below the axis of the pin 11 in its natural state. The gravity self-locking design allows the device to automatically reset to the locked position, ensuring that the device remains in a protective state even if the operator forgets to operate it.

[0027] In the anti-lifting device of this embodiment, such as Figure 6 , Figure 7 As shown, the connecting rod 10 is connected to the limiting part 8; the angle between the extending direction of the connecting rod 10 and the extending direction of the limiting rod 9 is 60°.

[0028] With the above configuration, the angle between the connecting rod 10 and the limiting part 8 is 60°. This angle balances structural strength and clearance: if the angle is too small, the coverage area of ​​the limiting part 8 will be insufficient; if it is too large, it is easy to collide with the second fixing part 3. Tests have shown that 60° ensures smooth operation of the mechanism.

[0029] like Figure 3 , Figure 6 As shown, in the anti-lifting device of this embodiment, there is an movable gap between the limiting part 8 and the second fixing part 3; and / or, the end of the limiting part 8 near the second fixing part 3 has a rounded corner 15.

[0030] With the above configuration, a movable gap is provided between the limiting part 8 and the second fixed part 3, and the end of the limiting part 8 is machined with a rounded corner 15. The gap compensates for assembly errors and avoids jamming; the rounded corner 15 reduces wear on the part 4 to be limited and collisions with it.

[0031] like Figure 3 , Figure 4 As shown, in the anti-lifting device of this embodiment, the first fixing component 2 and the second fixing component 3 are two mutually perpendicular plate structures.

[0032] Specifically, the first fixing component 2 and the second fixing component 3 are vertically welded plate structures. In this way, the right-angle layout maximizes the utilization of the limiting space 5, while providing double-sided support for the base 1 and improving torsional strength.

[0033] The working process of the anti-lifting device in this embodiment is as follows: Locking: Lower the limiting component 4. The limiting component 4 presses down on the connecting rod 10, pushing the limiting rod 9 to rotate. After the limiting component 4 automatically engages with the limiting space 5, the limiting rod 9 returns to its original position under gravity. See below. Figure 1 At this time, the abutting part 7 abuts against the base 1, and the limiting part 8 is located above the part to be limited 4, thereby limiting the part to be limited 4 and preventing it from coming off.

[0034] Unlock: Lift the pressure rod 13, the limiting part 8 rotates to avoid it, and the limiting part 4 can be moved out freely.
