Description

Lifting platform

Technical Field

The utility model relates to a lift platform, more specifically the theory that says so relates to a lift platform that uses when being used for luggage safety inspection.

Background

At present, whether the luggage of passengers has contraband or not needs to be checked in a plurality of areas such as ports, docks, bus stations and the like, the luggage cannot be completely checked after being checked by equipment such as an X-ray machine and the like, and the passengers need to be contacted to open a bag for checking together. The corresponding staff opens the bag of different sizes every day, needs to do a plurality of actions. Inconvenient operation and poor experience. Passenger luggage needs to be unpacked and checked in a security check area, and the size of the bag carried by each passenger is different, and the heights of people are different. Therefore, when the baggage is unpacked and checked again, the baggage needs to be frequently stooped down. For some big heavier luggage, if carry the higher position with luggage, it is hard to waste time, inconvenient people's operation to because the intensity of labour who carries luggage is big, there is the strain hidden danger to relevant personnel.

Disclosure of Invention

The utility model aims to overcome the technical problem that in the prior art, when the safety inspection is carried out on transportation hubs such as airports, ports, docks or stations, the luggage of passengers can be manually carried and lifted to complete the safety inspection process; the utility model provides a reliable durable, automatic lift platform, this platform passes through automatic lift luggage, can be with convenient the rising of luggage to treating the security check height, labour saving and time saving.

In order to realize the technical purpose, the technical proposal of the utility model is that:

the utility model provides a lifting platform, including the base, be equipped with the lift lead screw on the base, the bottom and the base pivot of lift lead screw are connected, the top of lift lead screw is provided with the lift ring, and the lift ring is located in the lift rack, the lift ring be equipped with lift lead screw external screw thread assorted ring internal thread and with the lift lead screw rotates relatively and forms the vertical lift stroke, and the lift lead screw is connected with first synchronizing wheel, first synchronizing wheel is connected with the second synchronizing wheel through the hold-in range, the second synchronizing wheel is driven by servo motor, servo motor is connected with motor circuit.

Furthermore, a first vertical guide post is arranged between the base and the lifting rack.

Furthermore, a linear bearing is arranged between the first vertical guide post and the lifting rack.

Furthermore, a second vertical guide post is arranged between the base and the lifting rack.

Furthermore, a linear bearing is arranged between the second vertical guide post and the lifting rack.

Furthermore, a plane table top is arranged on the lifting rack.

Furthermore, a lining wood board is arranged in the plane table-board.

Furthermore, the base is provided with a lower limit switch at the lower stroke limit of the lifting rack.

Furthermore, the base is provided with an upper limit switch at the upper travel limit position of the lifting rack.

The utility model has the beneficial technical effects that: the transmission of the lifting screw rod achieves the purpose of self-locking through reasonable lead design, and if power is cut off accidentally, the platform keeps self-locking, so that the operation safety of people is guaranteed. Meanwhile, the lifting rack is guided by a linear bearing when lifted, so that the platform is ensured not to shake, and the noise is reduced. The lifting screw rod only transmits upward axial thrust, so that the service life of the equipment is prolonged; through the flexible combination connection of hold-in range and synchronizing wheel, avoid the platform motion route with servo motor mounted position, reduce equipment size, convert the rotary motion of lift lead screw into the vertical lift motion of lift rack. When the luggage is small, the lifting button is pressed down, and the lifting rack drives the luggage to be lifted to a proper position, so that the luggage is convenient for workers to open bags for checking. On the contrary, when the corresponding great luggage, can reduce according to luggage self height, reduce the staff and operate the degree of difficulty. The screw rod transmission achieves the purpose of self-locking through reasonable lead design, the purpose is achieved by enabling the platform to act through motor driving, and if power is cut off accidentally, the platform keeps self-locking, so that the operation safety of people is guaranteed. Meanwhile, the platform is guided by the linear bearing when lifted, so that the platform is ensured not to shake, and the noise is reduced. The utility model adopts the lifting screw rod transmission to realize self-locking and is suitable for the luggage with different weights; and adopt lift lead screw transmission and optical axis direction, realize converting the motor rotary motion into vertical motion.

Detailed Description

With reference to fig. 1, a detailed description of the present invention will be given without limiting the claims. A lifting platform comprises a base 100, wherein the base 100 can adopt a metal frame structure for supporting an upper part, a lifting screw rod 101 is arranged on the base 100, and the lifting screw rod 101 can adopt a metal screw rod with the outer diameter of 5cm-10 cm; the height may be set between 0.5 and 1.5 meters; in an implementation, the bottom of the lifting screw 101 is connected with the rotating shaft of the base 100, so as to be fixed on the base and rotatable at the same time, a lifting ring 206 is disposed above the lifting screw 101, the lifting ring 206 is disposed in the lifting rack 205, and in a preferred embodiment, a corresponding lifting thread may be disposed between the lifting ring 206 and the lifting rack 205 to achieve adjustment and fixation. The inner side of the lifting ring 206 is provided with a ring internal thread matched with the external thread of the lifting screw rod 101 and rotates relative to the lifting screw rod 101 to form a vertical lifting stroke, the lifting screw rod 101 is connected with a first synchronizing wheel 203, and during implementation, the synchronizing wheel can be made of aluminum materials or other metal materials; the first synchronous 203 wheel is connected with a second synchronous wheel 202 through a synchronous belt 207, the second synchronous wheel 202 is driven by a servo motor 201, and the servo motor 201 is installed and fixed in the base 100 during implementation; the servo motor 205 is connected to a motor circuit. A first vertical guide post 102 is arranged between the base 100 and the lifting platform 205. A linear bearing is arranged between the first vertical guide post 102 and the lifting rack. A second vertical guide column 113 is arranged between the base 100 and the lifting platform 205.
