[0021] The utility model provides a steel structure shaft column lifting and adjusting device, including a bottom shaft 101, multiple leveling mechanisms, an upper shaft 102, multiple connecting rods 103 and multiple V-shaped rods 104, each of the leveling mechanisms includes a nut 105, an anchor plate 106, a full-thread lifting screw 107 and a limiting unit, the limiting unit includes a gear 108, a shell 109, a limiting rod 110, a spring 111, a ring 112, a pull ring 113, a guide rail 114 and a slide plate 115, and the anchor plate 106 has a threaded hole 116.
[0022] With respect to this specific embodiment, the limiting rod 110 is first pulled to cancel the adaptation of the limiting rod 110 to the gear 108, thereby canceling the limitation of the gear 108 and the full-thread lifting screw 107, and setting the bottom well 101 at the lowest position. When leveling is required, the full-thread lifting screw 107 is screwed to make the nut 105 extend out of the bottom of the anchor plate 106 and then support the end face of the pit. Then the limiting rod 110 is loosened, and under the elastic force of the spring 111, the limiting rod 110 returns to its original position and adapts to the gear 108 again, thereby limiting the full-thread lifting screw 107 and preventing the nut 105 from moving. Therefore, the device is positioned and balanced by screwing the full-thread lifting screw 107, saving manpower and time. The pull ring 113 makes it convenient for the staff to pull the limit rod 110 to move, and avoids the situation where the staff directly pulls the limit rod 110 and easily slips, and the pulling fails. When the limit rod 110 moves, the cooperation of the guide rail 114 and the slide plate 115 makes the movement of the limit rod 110 more stable, reduces its shaking, and can smoothly cooperate with the gear 108. The upper shaft 102 is used for connecting and installing elevators. The corresponding number of upper shafts 102 can be set according to the actual floors. Through the setting of multiple connecting rods 103, the supporting strength of the bottom shaft 101 is improved, making it more firm and reliable. Through the setting of multiple V-shaped rods 104, the supporting strength of the upper shaft 102 is improved, making the elevator more stable during operation and improving safety.
[0023] Among them, the anchor plate 106 is fixedly connected to the bottom well 101, the nut 105 is adapted to the threaded hole 116, the full-thread lifting screw 107 is fixedly connected to the upper end of the nut 105, the shell 109 is fixedly connected to the anchor plate 106, the gear 108 is fixedly connected to the upper end of the full-thread lifting screw 107, one end of the limit rod 110 passes through the shell 109 and is adapted to the gear 108, the ring 112 is fixedly sleeved on the outside of the limit rod 110 and is located inside the shell 109, and the two ends of the spring 111 are respectively fixedly connected to the inner wall of the shell 109 and the ring 112. First, pull the limit rod 110 to cancel the adaptation of the limit rod 110 to the gear 108, thereby canceling the limitation of the gear 108 and the full-thread lifting screw 107, and setting the bottom well 101 at the bottom. When leveling is required, the full-thread lifting screw 107 is screwed to make the nut 105 extend out of the bottom of the anchor plate 106 and then support the end face of the pit. Then, loosen the limit rod 110, and under the elastic force of the spring 111, the limit rod 110 returns to its original position and adapts to the gear 108 again, thereby limiting the full-thread lifting screw 107 and preventing the nut 105 from moving. Therefore, the device is positioned and balanced by screwing the full-thread lifting screw 107, saving manpower and time.
[0024] Secondly, the pull ring 113 is fixedly connected to the end of the limit rod 110 away from the full-thread lifting screw 107. Through the pull ring 113, it is convenient for the staff to pull the limit rod 110 to move, avoiding the situation where the staff directly pulls the limit rod 110 and easily slips and fails to pull.
[0025] At the same time, the guide rail 114 is fixedly connected to the inner wall of the housing 109, one end of the slide 115 is slidably adapted to the guide rail 114, and the other end of the slide 115 is fixedly connected to the limiting rod 110. When the limiting rod 110 moves, the cooperation between the guide rail 114 and the slide 115 makes the movement of the limiting rod 110 more stable, reduces its shaking, and thus can smoothly cooperate with the gear 108.
[0026] In addition, the upper shaft 102 is fixedly connected to the bottom shaft 101 and is located at the upper end of the bottom shaft 101. The upper shaft 102 is used to connect and install elevators, and a corresponding number of upper shafts 102 can be set according to the actual floors.
[0027] Furthermore, a plurality of connecting rods 103 are respectively provided on the four sides of the bottom shaft 101, and a plurality of V-shaped rods 104 are respectively provided on the four sides of the upper shaft 102. The provision of the plurality of connecting rods 103 improves the supporting strength of the bottom shaft 101, making it more solid and reliable. The provision of the plurality of V-shaped rods 104 improves the supporting strength of the upper shaft 102, making the elevator more stable and safer during operation.
[0028] When using the steel structure well column jacking adjustment device of the present invention, the limiting rod 110 is first pulled to cancel the adaptation of the limiting rod 110 and the gear 108, thereby canceling the restriction of the gear 108 and the full-thread jacking screw 107, and setting the bottom well 101 to the lowest position. When leveling is required, the full-thread jacking screw 107 is screwed to make the nut 105 extend out of the bottom of the anchor plate 106, and then support the end face of the pit, and then the limiting rod 110 is loosened. Under the elastic force of the spring 111, the limiting rod 110 returns to its original position and adapts to the gear 108 again, thereby limiting the full-thread jacking screw 107 and preventing the nut 105 from moving. Therefore, the device can be positioned and balanced by screwing the full-thread jacking screw 107, saving manpower and Time is saved. The pull ring 113 makes it easy for the staff to pull the limit rod 110 to move, avoiding the situation where the staff directly pulls the limit rod 110 and easily slips, and the pulling fails. When the limit rod 110 moves, the cooperation of the guide rail 114 and the slide plate 115 makes the movement of the limit rod 110 more stable, reduces its shaking, and can then smoothly cooperate with the gear 108. The upper shaft 102 is used for connecting and installing elevators. The corresponding number of upper shafts 102 can be set according to the actual floors. Through the setting of multiple connecting rods 103, the supporting strength of the bottom shaft 101 is improved, making it more firm and reliable. Through the setting of multiple V-shaped rods 104, the supporting strength of the upper shaft 102 is improved, making the elevator more stable during operation and improving safety.
