Description

Technical Field

[0001] This utility model relates to the field of traction freight elevator technology, specifically a traction freight elevator with a buffer structure. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves on at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15° to the vertical. The size and structure of the car facilitate passenger entry and exit or loading and unloading of goods.

[0003] According to the patent application published on the Internet (authorization announcement number: CN213265238U), "This utility model discloses a traction freight elevator with an anti-collision buffer structure, including an elevator shaft, a pit at the bottom of the elevator shaft, a machine room at the top of the elevator shaft, guide rails fixedly installed on the left and right sides of the elevator shaft, a drive motor fixedly installed in the machine room, a mounting seat fixedly installed on the drive motor, and a drive wheel movably installed on the mounting seat. This traction freight elevator with an anti-collision buffer structure has two exits, front and rear, for convenient transportation of goods. Anti-collision plates and anti-collision interlayers are fixedly installed on the top and bottom of the car. The anti-collision plates are made of wood, and the interlayer is made of rubber, which can effectively prevent the elevator from being damaged by impact. Shock-absorbing springs and shock-absorbing plates are installed in the pit. Support seats are fixedly installed on the top and bottom of the car to increase the load capacity of the elevator. Reducers and reduction wheels are fixedly installed on both sides of the support seats so that the car can stop slowly when it reaches the floor, preventing the car from shaking and causing material spillage due to sudden stopping."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model uses a traction rope fixed at both ends to the bottom of the machine room and passing around the traction wheel, drive wheel, and counterweight wheel. The drive motor drives the drive wheel to rotate, causing the car to rise and fall. The anti-collision plate 1, anti-collision interlayer 1, anti-collision plate 2, anti-collision plate 3, anti-collision interlayer 2, and anti-collision plate 4 on the car prevent the car from being damaged by impact. However, in actual use, because the goods are simply placed inside the car, it is inconvenient for staff to move them and the goods are prone to shaking, affecting the use. Therefore, it is necessary to improve the traction freight elevator with a buffer structure to solve the above problems. Utility Model Content

A transfer frame 713 is fixedly connected to the top of the movable plate 717. A caster wheel 714 is fixedly connected to the bottom of the transfer frame 713 to facilitate adjustment of the position of the transfer frame 713, thereby facilitating the transfer of goods by staff.

[0033] Furthermore, the movable plate 717 is threadedly connected to the threaded rod 715, and the connecting table 711 has a groove at the corresponding position of the movable plate 717, and the movable plate 717 is slidably connected inside the groove, which facilitates a more stable transfer process.

[0034] Furthermore, the adjustment assembly 72 includes a connecting frame 721, which is slidably connected inside the transfer frame 713.

[0036] Example 2:

[0037] Please see Figure 7 Furthermore, in conjunction with Embodiment 1, the shock absorption and protection mechanism 8 includes a support column 81, which is fixedly connected to the inner side of the bottom of the freight elevator car 5. A damping rod 82 is fixedly connected to the top of the support column 81. A movable frame 83 is slidably connected to the outside of the support column 81. A slide rail 84 is fixedly connected to the outside of the movable frame 83. A second spring 85 is fixedly connected inside the slide rail 84. A slider 86 is fixedly connected to the end of the second spring 85 away from the slide rail 84. A first connecting rod 87 is rotatably connected to the outside of the slider 86. A second connecting rod 88 is rotatably connected to the outside of the slider 86.

[0039] In actual operation, when this device is used, the traction motor 3 first works, in conjunction with the counterweight device 4, to move the freight elevator car 5 up and down. Then, the staff places the goods inside the freight elevator car 5 and adjusts the size according to the goods. The staff pulls the lever 723, which, in conjunction with the first spring 724, moves the locking block 725, thus achieving the limiting position between the connecting frame 721 and the transfer frame 713. The drive motor 712 then works, causing the threaded rod 715 to rotate, thus... The movable plate 717 moves, cooperating with the casters 714 to move the transfer frame 713. When the freight elevator car 5 is running, if the goods shake or vibrate, the connecting plate 6 moves. The movement of the connecting plate 6 causes the movable frame 83 to move. The movement of the movable frame 83, in conjunction with the second connecting rod 88 and the damping rod 82, causes the slider 86 to slide inside the slide rail 84. In conjunction with the first connecting rod 87 and the damping rod 82, the movable frame 83 slides outside the support column 81 to reduce vibration when the goods shake or vibrate.
