Detailed Description
Referring to fig. 1 to 3, the anti-climbing electric power iron tower of the present invention includes a tower body 100, an anti-climbing device 200 is disposed at a height section of the tower body 100, the height position may be selected according to an actual site and an actual need, the number of the anti-climbing devices 200 is not limited, and a plurality of sets of such anti-climbing devices 200 may be disposed at different heights of the tower body 100, thereby realizing multiple anti-climbing.
The rotatable mechanism comprises a control end assembly 230 and a controlled end assembly 210, the control end assembly 230 is positioned below the controlled end assembly 210 at a certain distance, the control end assembly 230 and the controlled end assembly 210 are in transmission connection by adopting a chain wheel and chain assembly 220, and the controlled end assembly 210 can be arranged at the same height as the anti-climbing support rod 201 or at a position higher than the anti-climbing support rod 201, so that the controlled end assembly 210 is less prone to be damaged; the anti-climb strut 201 is well assured of maintaining an anti-climb state as long as the controlled end assembly 210 is not damaged.
Specifically, the controlled end assembly 210 includes a first housing 211, a strut pivot 216, a torsion spring member 213 and a first torque adjustment assembly 212, the strut pivot 216, the torsion spring member 213 and the first torque adjustment assembly 212 are all disposed in the first housing 211, the at least one anti-climbing strut 201 is connected to the strut pivot 216, the torsion spring member 213 is sleeved on the strut pivot 216, and the first torque adjustment assembly 212 is connected to the strut pivot 216 and is configured to drive the strut pivot 216 to rotate by overcoming a torque of the torsion spring member 213. The shaft rotating shaft 216 is disposed in the first housing 211, and then the torsion spring member 213 is disposed in the housing, and the torsion spring member 213 is a torsion spring with a large torsion force, so that when a general person pulls the anti-climbing shaft 201, the rotation of the torsion spring member 213 cannot be overcome. The strut rotating shaft 216 is connected with the first torque adjusting assembly 212, the first torque adjusting assembly 212 is formed by gear sets with different sizes, and the torque can be increased through arrangement of gear shafts, so that the control end assembly 230 can conveniently rotate the strut rotating shaft 216.
The control end assembly 230 and the controlled end assembly 210 realize transmission at a certain distance through the chain wheel and chain assembly 220, on one hand, when an operator operates the control end assembly 230, the rotating anti-climbing support rod 201 cannot touch the operator, on the other hand, the certain distance is realized, the controlled end assembly 210 is also protected, and the controlled end assembly 210 can be designed to be slightly above the position and is not easy to damage.
Further, since the first case 211 has an opening necessary for the rotation of the anti-climb rod 201, the anti-climb rod 201 is connected to the rod rotating shaft 216 in the first case 211 through the opening, and the opening can accommodate the rotation of the anti-climb rod 201 from the horizontal position to the position in close contact with the tower body 100, the opening is large in position opening, and a hard object is easily inserted, which may damage the torsion spring member 213, the torque adjusting unit, and the like in the first case 211. In order to prevent hard objects from entering, a link plate member 214 is further disposed in the opening portion, the link plate member 214 can slide along both sides of the opening portion, has a certain protection strength similar to a rolling door structure, and can be contracted and folded, and a first elastic member 215 is disposed in the first box body 211 below the opening portion for supporting the link plate member 214 to a position closing the opening portion. The first case 211 may be provided with a receiving space for receiving the link plate member 214 therein, and then the first elastic member 215 may be disposed at an end of the receiving space to support the link plate member 214, so as to ensure that the link plate member 214 can be kept relatively closed to the opening portion at any time, and at the same time, due to the presence of the first elastic member 215, the first elastic member 215 may be an elastic member with a larger elastic force, which cannot open the link plate member 214 when a general force is applied, so that the link plate member 214 further enhances the support of the anti-climbing rod 201, so that the rotation resistance of the anti-climbing rod 201 may be larger, the rotation of an ordinary person may be more difficult, and the anti-climbing safety may be further enhanced. When the anti-climbing support rod 201 needs to be rotated, the first torque adjusting assembly 212 can overcome the torsion force of the torsion spring member 213 to rotate the anti-climbing support rod 201, and meanwhile, the chain plate member 214 can be driven to compress the first elastic member 215 by the rotation of the anti-climbing support rod 201 to achieve the storage of the chain plate member 214.
The first elastic member 215 may be a coil spring, and a plurality of the first elastic members are arranged side by side, and when one coil spring is insufficient in elasticity, a plurality of the first elastic members may be provided, and of course, other elastic members may be used to realize the first elastic member.
The control end assembly 230 comprises a second box 231, a second torque adjusting assembly 232 and a special control rod for being in plug-in fit with the second torque adjusting assembly 232, and a locking assembly is arranged on the second box 231 and used for locking the at least one anti-climbing support rod 201 when the anti-climbing support rod is rotated to a position close to the tower body 100. The second torque adjustment assembly 232 is also formed by gear sets of different sizes, and the arrangement of the gear shafts can increase the torque, so that the easiness of overcoming the resistance of the torsion spring member 213 and the first elastic member 215 is further improved, and the labor is saved for an operator. The special control rod adopts a plug-in structure with a specific end, and the second torque adjusting assembly 232 is difficult to rotate when a common rod-shaped component is plugged in, so that various special-shaped structures can be adopted usually. The second torque assembly is arranged in the second box 231, and a hole portion into which the special control rod can be inserted is formed in the second box 231, and the hole portion is small, so that a destructive person can hardly observe the insertion position connecting hole in the second torque adjustment assembly 232 through the hole portion, and the special control rod is not easy to imitate.
And the locking assembly can conveniently lock the anti-climbing support rod 201 when the anti-climbing support rod 201 rotates to the position close to the tower body 100, so that maintenance personnel can conveniently pass through the anti-climbing support rod 201 smoothly. The locking assembly comprises a second elastic member 235 and a limiting block connected to the second elastic member 235, the end portion of the anti-climbing support rod 201 is provided with a barb portion, and when the anti-climbing support rod 201 rotates to a position close to the tower body 100, the limiting block can be clamped to the barb portion. The limiting block adopts a wedge-shaped block structure which can facilitate the cut-in of the barb part, and the barb part can extrude the limiting block to overcome the elasticity of the second elastic component 235 and smoothly cut into the barb part without exiting.
When the release is needed, the stopper is connected with a sliding control rod 234 for moving the stopper to withdraw from the barb part. The sliding control rod 234 can be conveniently slid to overcome the elastic force of the second elastic member 235, and then the stopper is withdrawn from the barb portion, so that the climbing prevention rod can be automatically reset. In order to avoid damage to the opening part due to overlarge restoration when the climbing-prevention rod is reset, the edge of the opening part is provided with a damping component, so that the climbing-prevention rod can well play a role in protection.
The second elastic member 235 may be a gas spring, or other elastic members may be used.
