Description

Technical Field

[0001] This invention relates to the field of safety clamp technology, specifically to a support structure for safety clamps and its support method. Background Technology

[0002] According to a patent published on the China Patent Network, the patent title is "An Eccentric Wheel-Type Safety Gear Structure for Elevators," patent number 202111006050.7. This invention relates to the field of elevator equipment technology and discloses an eccentric wheel-type safety gear structure for elevators. It includes an elevator guide rail, with a first housing and an eccentric wheel-type safety gear respectively sleeved on the outer side of the middle of the guide rail. The eccentric wheel-type safety gear is sleeved inside the first housing, and a servo motor is connected to one side of the eccentric wheel-type safety gear. The invention uses the servo motor, a first air pressure component, a locking mechanism, and a small battery to form a restart mechanism, which then interacts with the eccentric wheel-type safety gear. If the associated speed governor, tensioner, and wire rope fail, the elevator will plummet. The speed difference between the front and rear of the elevator can change the rotation speed of the first blade inside the first air pressure component, thereby increasing the pushing force on the baffle. This causes the baffle to touch the microswitch, activating the servo motor to perform a secondary emergency start on the eccentric wheel safety gear, ultimately achieving emergency braking of the elevator car and preventing an accident. However, the safety gear mentioned above is supported by its own vertical rod. The support provided by the vertical rod is insufficient, and it is prone to collapse under external interference, resulting in damage to the safety gear and affecting its subsequent normal use.

[0003] Therefore, the safety clamp needs to be redesigned and modified to effectively prevent insufficient support. Summary of the Invention

[0006] Safety clamp mechanism;

[0007] The reinforced support mechanism is fixedly connected to both sides of the safety clamp mechanism. Each reinforced support mechanism includes two reinforced support boxes. A motor is fixedly connected to the front side of the inner cavity of each reinforced support box. A worm gear is fixedly connected to the output end of the motor. A rotating rod is laterally connected to the inside of each reinforced support box via bearings. A worm wheel is sleeved on the front side of the rotating rod surface, and the outer side of the worm wheel meshes with the worm gear. A gear ring is sleeved on the rear side of the rotating rod surface. A gear plate is provided on the inner side of the gear ring, and the outer side of the gear plate meshes with the gear ring.

The bottom of the reinforced support block extends to the bottom of the safety clamp mechanism. A blocking mechanism is fixedly connected to the front side of the top of the safety clamp mechanism.

[0008] As a preferred embodiment of the present invention, the safety clamp mechanism includes a housing assembly, wherein clamps are provided on both sides of the back side of the housing assembly, and slots are provided on both sides of the front side of the housing assembly.

[0009] In a preferred embodiment of the present invention, the shielding mechanism includes a shielding box.

[0019] 2. The present invention, through the setting of the safety clamp mechanism, can prevent the machine or equipment from sliding due to excessive load or abnormal conditions during operation. When the equipment is involved in an accident, the safety clamp will lock quickly to prevent the equipment from sliding or operating abnormally, thereby protecting the safety of the machine and the operator.

[0047] As a technical optimization of the present invention, by setting the limiting wheel rod 7, the bar rod 29 can move up and down more stably, avoiding the phenomenon of the bar rod 29 wobbling.

[0048] S1: First, when support is needed, start motor 22. The output end of motor 22 drives worm 23 to rotate, worm 23 drives worm wheel 25 to rotate, worm wheel 25 drives rotating rod 24 to rotate, rotating rod 24 drives gear ring 26 to rotate, gear ring 26 drives gear plate 27 to move downward, gear plate 27 drives bar 29 to move downward through slide plate 28, bar 29 drives reinforcing support block 210 to move downward, so that reinforcing support block 210 extends to the bottom of safety clamp mechanism 1, thereby achieving the effect of increasing support.

[0049] S2: Then, when it is necessary to cover the slot 13, start motor 2 32. The output end of motor 2 32 drives the rotary table 33 to rotate. The rotary table 33 drives one end of the connecting rod 34 to rotate. The other end of the connecting rod 34 drives the pin 35 to move inward. The pin 35 drives the connecting plate 36 to move inward. The connecting plate 36 drives the blocking plate 37 to move inward, so that the blocking plate 37 blocks the front of the slot 13, thereby preventing dust from entering the interior of the slot 13 and increasing its cleanliness.

[0050] The working principle and usage process of this invention are as follows: First, when support is needed, motor 22 is started.

This can increase the support effect. Then, when it is necessary to cover the slot 13, the second motor 32 is started. The output end of the second motor 32 drives the rotary table 33 to rotate. The rotary table 33 drives one end of the connecting rod 34 to rotate. The other end of the connecting rod 34 drives the pin 35 to move inward. The pin 35 drives the connecting plate 36 to move inward. The connecting plate 36 drives the blocking plate 37 to move inward, so that the blocking plate 37 blocks the front of the slot 13, thereby preventing dust from entering the interior of the slot 13 and increasing its cleanliness.

[0051] In summary, the support structure and method of this safety clamp overcome the shortcomings of traditional methods that are prone to collapse due to insufficient support. By using a bar 29 to move the reinforcing support block 210 downward, the reinforcing support block 210 supports the safety clamp mechanism 1. Under external interference, it will not collapse, will not be damaged, and will not affect its normal use.
