Wherein, a semicircular movable clamping head 9 is arranged on the clamping groove, one end of the movable clamping head 9 is connected with one end of an extension rod 8, the middle part of the extension rod 8 is hinged on a buckle base 7, the other end of the extension rod 8 is connected with one end of an arc locking buckle 2, the other end of the arc locking buckle 2 is hinged on the buckle base 7 through an elastic element (such as a torsional spring or a pressure spring), and a handle is arranged on the arc locking buckle 2, so that the movable clamping head 9 can be opened by pulling the handle; wherein, the arc-shaped fixed buckle 1 is also hinged on the buckle base 7 through an elastic element (such as a torsion spring or a pressure spring), one end of the arc-shaped fixed buckle 1 is provided with a hook so as to block the movable clamping head 9, and the other end of the arc-shaped fixed buckle 1 is provided with a handle, which can release the hook on the arc-shaped fixed buckle 1 by pressing the handle. In addition, the top surface of the crescent protection block 3 is provided with anti-skid grains 4.
The utility model discloses a use method and theory of operation are:
when the safety rope crossing structure is used, a safety rope connecting hole of the buckle base 7 is connected with a personnel protection rope, a semicircular clamping groove is formed in the middle of the buckle base 7 at the high position of a steel pipe crossing frame vertical rod, the steel pipe is clamped, the top crescent protection block 3 of the ejector rod 6 tightly pushes the surface of the steel pipe, the handle on the arc-shaped locking buckle 2 is loosened to reset the movable clamping head 9 under the action of the elastic element, namely, the steel pipe is clamped, then the handle on the arc-shaped fixing buckle 1 is loosened to enable the hook on the arc-shaped fixing buckle 1 to clamp the boss on the edge of the movable clamping head 9 under the action of the. After finishing using, press down in proper order the handle on the fixed buckle 1 of arc and the handle on the dead buckle 2 of arc lock can open movable dop 9, take off from the steel pipe the utility model discloses the device.
Example 1:
the utility model provides a steel pipe crossing structure personnel protection device, including dual arc buckle, protection mechanism and connection handle. The connecting handle is provided with an arc-shaped fixing buckle 1, an arc-shaped locking buckle 2 and a triple protection mechanism. The connecting handle enables the device to be locked on the steel pipe crossing frame upright rod through the double arc-shaped buckles and the triple protection mechanisms, and a rear ring (a safety rope connecting hole) of the connecting handle is connected with the protection rope and personnel.
The utility model discloses a use method and theory of operation are: in the process of erecting the steel pipe crossing frame, the personnel protection device is used for hanging the steel pipe crossing frame at a high position, a buckle is arranged at the high position of the upright rod of the steel pipe crossing frame through a fixed buckle, the device is locked by the arc-shaped locking buckle 2, the crescent protection block 3 is tightly attached to the steel pipe through the protection spring 5, and a personnel protection rope is connected to the rear ring of the handle. In the work progress, protection device is when receiving the impact force to the card is died in the steel pipe pole setting to certain angle slope, simultaneously through 4 frictional force effects of anti-skidding line and protection machanism's holding power, prevents that protection device atress from gliding, thereby reduces the eminence and sets up personnel's risk of falling, has effectively ensured personnel's safety.
Through the effectual convenience that has realized protection device of the fixed buckle of arc 1. Through the fixed buckle 1 of arc, contact fulcrum and tie point atress, the buckle slides along steel pipe pole setting surface, can realize protection device's quick latch closure, and is easy and simple to handle.
The connection reliability of the protection device is effectively realized by designing the arc-shaped locking buckle 2. Dead buckle 2 front end baffle of lock through the arc is connected with fixed buckle, and the horizontal rotation displacement of fixed buckle is restricted, plays two guard action, and the effectual protection device buckle that has avoided causing because of receiving the impact force is from the unblock risk, ensures that the device connects reliably.
Through crescent protection piece 3's design, protection device and dual arc buckle synergism ring are detained in the steel pipe crossing structure pole setting to when receiving the impact force, with certain angle slope card dead, the effectual personnel that have realized fall the protection. Simultaneously, the crescent design is in accordance with the steel pipe structure, so that the contact surface between the protection mechanism and the steel pipe is increased, a good anti-slip effect is achieved, the stress of the protection mechanism is uniform when the protection mechanism is impacted, the protection mechanism is not easy to damage, and the service life is long.
Increase contact surface roughness through anti-skidding line 4, play the effect of increase friction power, in the construction of setting up, effectively avoid the device gliding that causes because of steel pipe vibrations when personnel's operation.
Through the elastic force effect of protection spring 5, make protection device and steel pipe crossing structure pole setting fully contact to with anti-skidding line 4 synergism, prevent to shake gliding. Meanwhile, when the protection mechanism is impacted, the protection mechanism is limited and buffered to a certain extent through the rebound force of the spring; can carry out the compression in the elasticity scope under the horizontal atress condition, make protection device can reciprocate under the condition of not opening dual buckle, easy and simple to handle, high efficiency, the effectual personnel of having solved reciprocate the security in setting up the construction.
Through the supporting force of the secondary protection mechanism, the limit of the inclination angle under the impact action is ensured, the use reliability of the device is improved, the secondary protection effect is achieved, and therefore the safety of high-altitude operation personnel is ensured.
