Description

Technical Field

[0001] The present invention relates to the technical field of column protection, and particularly to an anti-collision device for load-bearing columns. Background Art

[0002] In warehouse and factory environments, goods handling and vehicle driving are frequent, and load-bearing columns are extremely vulnerable to collision and abrasion.

Detailed implementation manners

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0052] Please refer to Figures 1-9 , the present invention provides a technical solution: a collision - proof device for a load - bearing column, including a column body 1, and further including:

[0053] Multiple groups of energy - releasing units 2, each group of energy - releasing units 2 is arranged in an arc shape, and the whole is arranged in a circular ring around the column body 1 in a circular array manner, for changing the movement trajectory of the impacting object and performing preliminary energy release. Among them, it mainly aims at the situation where goods handling and vehicle driving are frequent in the factory building, and the column body 1 may be collided accidentally;

[0054] Multiple groups of rotary support units, arranged between each group of the energy - releasing units 2 and the column body 1, and cooperating with the energy - releasing units 2 to change the impact path of the object and perform secondary energy release;

[0055] Among them, the rotary support unit includes:

[0056] A limiting rotation mechanism 3, arranged on the column body 1, when an object impacts on the energy - releasing unit 2, enabling the energy - releasing unit 2 to rotate around the column body 1 as an axis, and pulling the object to change its movement trajectory;

[0057] The connecting mechanism 4 is arranged between the limiting and rotating mechanism 3 and the energy releasing unit 2 for connecting the limiting and rotating mechanism 3 and the energy releasing unit 2.

[0058] Among them, the limiting and rotating mechanism 3 includes:

[0059] A fixed ring 31 fixedly arranged on the column body 1;

[0060] A rotating ring 32 is arranged on the outside of the fixed ring 31 in a limited rotation manner through a clamping member 33;

[0061] A limiting member 34 is arranged between the column body 1 and the rotating ring 32 for limiting the rotation angle of the rotating ring 32 and resetting after rotation;

[0062] In addition, the clamping member 33 includes:

[0063] A rotating groove 331 arranged on the fixed ring 31;

[0064] A clamping ring 332 arranged on the rotating ring 32 for the rotating ring 32 to rotate on the rotating groove 331. Ball bearings are arranged on the contact surface between the clamping ring 332 and the rotating groove 331 to reduce the friction of rotation.

[0065] Meanwhile, the limiting member 34 includes:

[0066] Two first fixing blocks 341 arranged on the upper and lower sides of the rotating ring 32;

[0067] Two second fixing blocks 342 arranged on the upper and lower sides of the column body 1. Hemispherical grooves are arranged on the first fixing blocks 341 and the second fixing blocks 342 on the side close to each other, and spheres 343 are arranged in both of the two hemispherical grooves;

[0068] A first spring telescopic rod 344 arranged between the two spheres 343.

[0069] Among them, the connecting mechanism 4 includes:

[0070] At least one group of second spring telescopic rods 41, one end of which is fixedly arranged on the rotating ring 32 and the other end is arranged on the corresponding energy releasing unit 2;

[0071] Two groups of third spring telescopic rods 42 are symmetrically arranged with the second spring telescopic rod 41 as the axis of symmetry and are obliquely arranged between the rotating ring 32 and the energy releasing unit 2. Both ends of the two groups of third spring telescopic rods 42 are rotatably arranged on the rotating ring 32 and the energy releasing unit 2 respectively.

[0072] In addition, the energy releasing unit 2 includes:

[0073] Two groups of arc-shaped mounting plates 21 are respectively rotatably arranged at the ends of the two third spring telescopic rods 42;

[0074] A telescopic plate 22 is arranged between the two groups of arc-shaped mounting plates 21. One end of the second spring telescopic rod 41 is slidably arranged on the telescopic plate 22, and a slide rail for the second spring telescopic rod 41 to slide is arranged on the telescopic plate 22;

[0075] Multiple groups of anti-collision rollers 23 are circularly and arrayedly distributed between the two groups of arc-shaped mounting plates 21;

[0076] A telescopic reset assembly 24 is arranged between the two ends of the anti-collision roller 23 and the arc-shaped mounting plate 21.

[0077] Meanwhile, the telescopic reset assembly 24 includes:

[0078] Two groups of limit sliding grooves 241 symmetrically arranged inside the roller shafts of the anti-collision rollers 23, and the two groups of limit sliding grooves 241 respectively penetrate through the upper and lower ends of the roller shafts;

[0079] Two groups of sliding rods 242, one end of each is limited and slid in the limit sliding groove 241 by arranging a limit circular plate, and the other end of each is fixed on the two groups of arc-shaped mounting plates 21;

[0080] A reset spring 243 is sleeved on the sliding rod 242 inside the limit sliding groove 241, one end abuts against the limit circular plate, and the other end abuts against the end of the limit sliding groove 241.

[0081] In addition, a limiting part 25 is arranged between the roller shaft of the anti-collision roller 23 and the arc-shaped mounting plate 21, which is used to limit the rotation angle of the anti-collision roller 23;

[0082] After an object hits the energy release unit 2, due to the impact force of the object, on the one hand, the energy release unit 2 rotates under the action of the limit rotation mechanism 3 to traction the impact object and change the traveling route of the object. On the other hand, through the rotation of the anti-collision roller 23 itself, the impact object can be tractioned again to assist in changing the traveling route of the object. In addition, due to the setting of the limiting part 25, during the process of changing the incoming line, since the contact position between the object and the energy release unit 2 will change due to its own movement, it will contact multiple different anti-collision rollers 23. Due to the setting of the limiting part 25, the anti-collision roller 23 will stop rotating after rotating and moving an angle. Therefore, after the anti-collision roller 23 contacts the object, the rotational traction will become sliding friction. After passing through multiple anti-collision rollers 23, the impact force of the object will be buffered to reduce the traveling speed of the object, so as to prevent the object from colliding with other components in the factory building for the second time;

[0083] In addition, after the object impacts the energy release unit 2, the impacted energy release unit 2 will approach the column body 1 side under the setting of the connecting mechanism 4, thereby forming a concave shape between two adjacent groups of energy release units 2, enabling the end of the object to be caught in the groove of the concave shape (wherein, in addition to the function of forming the concave shape, the connecting mechanism 4 can also buffer the force impacted by the object), so as to release energy under the cooperation of the limit rotation mechanism 3 and further prevent secondary collisions from occurring;

[0084] Finally, the limiting part 25 includes:

[0085] A first limiting plate 251 arranged at the end of the anti-collision roller 23 close to one side of the telescopic plate 22;

[0086] A second limiting plate 252 arranged on the arc-shaped mounting plate 21 to cooperate with the first limiting plate 251 for limiting. A torsion spring is arranged between the roller shaft of the anti-collision roller 23 and the sliding rod 242;

[0087] When the anti-collision roller 23 collides and rotates, after the first limiting plate 251 rotates a certain angle along with the roller shaft, it will stop rotating due to the limiting effect of the second limiting plate 252, thereby achieving the limiting effect, and after the collision treatment is completed, it will rotate and reset due to the action of the torsion spring.
