Example (b):

as shown in fig. 1-5, the present invention provides an iron tower convenient for climbing, which comprises a tower body 10, a lifting base 1 and a counterweight 2. The lifting seat 1 is provided with a carrying groove 11 for accommodating the balancing weight 9. The balancing weight 9 can be conveniently put into the object carrying groove 11 or taken out from the object carrying groove 11. The counterweight 2 is connected with the lifting seat 1 through a traction rope 3. The hauling cable 3 is connected with a fixed pulley 4 arranged at the top of the tower body 10. That is, the balance weight 2 and the lifting base 1 are located on both sides of the fixed sheave 4 and connected by the traction rope 3. When the weight 2 is lowered, the weight of the weight 2 causes the elevating base 1 to be raised upward. The lifting seat 1 is also provided with a driving mechanism 7 for driving the lifting seat to lift. The drive mechanism 7 may be a rope connected to the lifting platform 1 and passing around the fixed pulley 4. The lifting seat 1 can be lifted by pulling the rope. The drive mechanism 7 may be a drive motor or the like.

When the iron tower convenient to climb is used, the balancing weight 9 is put into the object carrying groove 11 according to the weight of the iron tower, so that the sum of the weight of a person, the weight of the lifting seat 1 and the weight of the balancing weight 9 is equivalent to the weight of the counterweight 2. At this time, the weight of both ends of the traction rope 3 is equivalent. The user can lift the lifting base 1 by applying a slight force to the driving mechanism 7, so that the user can conveniently climb to the top of the tower body 10 or descend from the top of the tower body 10 to the ground. And then reduce the physical power that people climbed the iron tower and consumed, raise the efficiency.

In this embodiment, the tower body 10 is vertically provided with a lifting rail 5. The lifting seat 1 is slidably disposed on the lifting rail 5. Specifically, two lifting rails 5 are provided. The lifting base 1 is provided with a locking piece 12 in cooperation with each lifting rail 5. The locking member 12 comprises three guide wheels 121. The three guide wheels 121 are respectively attached to the outer wall of the lifting rail 5, and the wrap angle of the three guide wheels 121 to the lifting rail 5 is 270 degrees. That is, the three guide wheels 121 respectively abut three surfaces of the lifting rail 5, and only one surface of the lifting rail 5 is not surrounded by the guide wheels 121. Meanwhile, the open sides of the two sets of locking members 12 are oppositely disposed. Two sets of retaining members 12 and two lift rail 5 cooperations make lift seat 1 can easily remove along lift rail 5, and lift seat 1 can not rock in the arbitrary direction in the horizontal plane. And then make the lift orbit of lift seat 1 confirm, guaranteed the stability of lift seat 1 lift in-process, also guaranteed the security.

In this embodiment, the tower 10 is provided with a rack 6 parallel to the lifting rail 5. The drive mechanism 7 includes a pedal 71 and a drive gear 72. The drive gear 72 is engaged with the rack 6. The pedal 71 has the same structure as the bicycle pedal 71, and includes two pedals 71 on the left and right and a rotation lever. The dwang is rotatable sets up in seat 1 that goes up and down. The driving gear 72 and the pedal 71 are in transmission connection through a worm gear 73 and a worm 74 which are matched with each other. The worm 74 is connected to the pedal 71 side. Specifically, the rotating rod of the pedal 71 and the worm 74 are both provided with a bevel gear 75. The two bevel gears 75 are coupled to each other. The worm gear 73 is coaxial with the drive gear 72.

When the pedal 71 is stepped on, the rotation lever rotates, and the worm 74 is rotated by the two bevel gears 75. The worm 74 rotates to drive the driving gear 72 to rotate along with the worm wheel 73. The cooperation of the driving gear 72 and the rack gear 6 can make the lifting base 1 lift relative to the lifting rail 5. The direction of stepping on the pedal 71 is different, and the moving direction of the lifting seat 1 along the lifting rail 5 is different, so that the lifting seat 1 can be lifted along the lifting rail 5. When the weight of the two ends of the hauling rope 3 is the same, the user can drive the lifting base 1 to ascend and descend by lightly stepping on the pedal 71, and then easily climb up the tower body 10 or descend from the top of the tower body 10. When the lifting seat is designed specifically, the reduction ratio between the rotating rod and the driving gear 72 can be adjusted, so that the stepping speed of the pedal 71 and the lifting speed of the lifting seat 1 are matched properly, and the pedal 71 can be stepped easily and the lifting seat 1 can be lifted quickly.

Meanwhile, the worm wheel 73 and the worm 74 are matched, so that when the pedal 71 stops stepping, the lifting seat 1 cannot lift along the lifting rail 5, and further potential safety hazards caused by free falling of the lifting seat 1 in the situations of user fatigue and the like are avoided.

In this embodiment, four sets of retaining members 12 are provided. The four groups of locking pieces 12 are distributed in a rectangular shape. Four sets of locking members 12 are fitted to the lifting rail 5. This makes the connection between the lifting seat 1 and the lifting rail 5 more stable, and ensures the safety of use.

In this embodiment, the two lifting rails 5 are connected by a plurality of connecting rods 52. Each connecting rod 52 is provided with a connecting rod 51 for connection to the tower 10. This allows the tower 10 to be connected to the connecting rods 51 without excessive changes in the structure of the tower, provided that the connection points are only preserved. Conveniently in combination with the tower 10. Meanwhile, the components of the lifting track 5, the lifting seat 1 and the like of the invention can be conveniently transformed and installed on the existing iron tower. In practice, the lifting rail 5 can be arranged at any desired position of the tower 10.

In this embodiment, the lifting seat 1 is provided with a lifting chair 13. The pedal 71 is provided at the lower portion of the elevating chair 13. The user sits on the lift chair 13 and steps on the pedal 71 to lift. In order to ensure safety, the lift chair 13 is also provided with a safety belt. The lifting seat 1 is also provided with armrests 14 so that a user can hold the armrests 14 while sitting on the lifting chair 13.

In this embodiment, one end of the pulling rope 3, which is far away from the lifting seat 1, is connected to the top of the tower body 10, and the connection point of the pulling rope 3 and the tower body 10 is lower than the height of the fixed pulley 4. A hanging rod 21 is arranged on the top of the counterweight 2. The boom 21 is provided with a movable sheave 22 fitted to the traction rope 3. When the pulling rope 3 is pulled to make the counterweight 2 rise, the counterweight 2 gradually deviates to the fixed side of the pulling rope 3 and the tower body 10. That is, the weight 2 does not rise vertically but moves obliquely upward during the rise.

The tower 10 is further provided with a hanger 8. The hanging piece 8 is arranged on the top of the counterweight 2. The hanging member 8 is provided with a moving groove 81 along the ascending trajectory of the tip end of the boom 21. The moving slot 81 is provided with two guide plates 82. The guide plate 82 can only be deflected in the ascending direction of the boom 21. Specifically, the guide plate 82 is hinged to a groove wall of the moving groove 81, and the guide plate 82 is provided with a torsion spring and the like, so that the other end of the guide plate 82 always abuts against the groove wall of the moving groove 81. When the boom 21 is obliquely raised, the top of the boom 21 gradually enters the inside of the moving groove 81 and gradually rises along the moving groove 81. When the top end of the boom 21 rises, the top end of the boom 21 pushes the guide plate 82 to deflect, so that the moving groove 81 is opened, and the top end of the boom 21 can smoothly pass through the guide plate 82. After the top end of the boom 21 passes through the guide plate 82, the guide plate 82 is returned by the elastic force of the torsion spring, thereby blocking the moving groove 81. Due to the unidirectional swinging of the guide plates 82, after the hauling cable 3 is loosened, the top end of the suspender 21 can only slide down along the guide plates 82 and further slide down to the bottom of the moving groove 81 in the hanging groove 83 arranged between the two guide plates 82. The top end of the hanging rod 21 is also provided with a hook 23 perpendicular to the hanging rod 21. The hook 23 is arranged in a matching manner with the hanging groove 83, so that the hook 23 can be well hung in the hanging groove 83. The counterweight 2 is then suspended by the suspending member 8.

The pulling rope 3 is pulled again, so that the weight 2 moves along the moving slot 81 again and passes through the other guide plate 82. When the pulling rope 3 is released again, the top end of the boom 21 slides down along the other guide plate 82 to the top end of the coupling moving groove 81 provided in the hook 8 and the unhooking passage 84 below the hook 8. Thereby disengaging the hitching member 8 from the unhooking channel 84. At this time, the weight 2 can be freely lowered without being bound by the hanging member 8.

The hanging piece 8 is arranged, so that the counterweight 2 can be fixed at a high position, and the counterweight 2 is put down when needed, so that the lifting seat 1 and a user can be lifted by the counterweight 2. The counterweight 2 is fixed on the hanging piece 8, so that the counterweight 2 is prevented from being in a free state when not used, and the safety is ensured. The hauling rope 3 is convenient to replace or overhaul. The hitching member 8 can be provided in two symmetrical halves. The two symmetrical halves are a whole, and a moving groove 81, a guide plate 82, a hanging groove 83 and a unhooking channel 84 are arranged in the two halves. The lower parts of the symmetrical halves are provided with grooves through which the hanger rods 21 pass. Meanwhile, the hooks 23 are arranged on two opposite sides of the top end of the suspender 21, so that the hooks 23 are more stably hung in the hanging grooves 83.

In this example, the weight 2 had a mass of 150 kg. According to the physical distance, when the total weight of the lifting seat 1 reaches half of the weight of the counterweight 2, the traction rope 3 bears the same force on the two sides of the fixed pulley 4. That is, when the total weight of the lifting seat 1 is 75kg, the force applied to both sides of the fixed pulley 4 by the traction rope 3 is the same. 75kg and most people's weight are right, make the balancing weight 9 of carrying thing groove 11 need not place too much, convenient operation.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
