Specific implementation mode
Example embodiment is described more fully with reference to the drawings.However, example embodiment can be with a variety of shapes
Formula is implemented, and is not understood as limited to embodiment set forth herein；On the contrary, thesing embodiments are provided so that this practicality is new
Type will be full and complete, and the design of example embodiment is comprehensively communicated to those skilled in the art.It is identical in figure
Reference numeral indicates same or similar structure, thus will omit their detailed description.
As shown in Figures 1 and 2, the utility model embodiment discloses a kind of boarding bridge elevating mechanism, including crossbeam 6,
Inner sleeve 5, outer tube 3, lead screw pair, main decelerating motor 1 and assisted deceleration motor 2.
Crossbeam 6 is respectively arranged an inner sleeve 5 in lower position horizontal and positioned at Boarding bridge access 4, both ends, this is interior
Casing 5 is fixedly connected on the crossbeam 6 vertically by connectors such as bolts.3 sliding sleeve of outer tube is set to inner sleeve 5, the outer tube 3
It is connect for the channel 4 with connecting bridge, to drive channel 4 to lift jointly, inner sleeve 5 and outer tube 3 can be cylinder type, also may be used
For other structures such as square tubes.
Lead screw pair is arranged within outer tube 3.In the present embodiment, the lead screw pair be ball screw assembly, 7, including with it is interior
The nut 72 that casing 5 is connected and the lead screw 71 with the nut 72 rotation connection.Lead screw pair in addition to using other than ball-screw,
The leading screw of other forms can also be used.The lead screw pair can also be arranged in the outside of outer tube 3, and with outer tube 3 and inner sleeve 5
It is arranged in parallel.
The output shaft of main decelerating motor 1 is connect with lead screw, is lifted with drive outer casing 3.In the present embodiment, main deceleration
The selection of motor 1 is horizontal machine, and output shaft 11 is the hollow shaft with vertical axis.The main decelerating motor 1 is set to outer
The top of casing 3.It can be inserted into the top of screw mandrel 71 in the centre bore of the output shaft 11 of the main decelerating motor 1.So,
Shaft coupling is can be omitted between lead screw 71 and main decelerating motor 1.The main decelerating motor 1 can also use vertical machine, meanwhile,
Solid shafting can also be used in the output shaft 11 of the main decelerating motor 1, and passes through the devices such as gear-box and lead screw 71 and assisted deceleration electricity
The output shaft 21 of machine 2 is attached.
The maximum (top) speed of assisted deceleration motor 2 is more than the maximum (top) speed of main decelerating motor 1, and the torque of output is smaller, and
Although the maximum (top) speed of main decelerating motor 1 is less than assisted deceleration motor 2, its torque ratio assisted deceleration motor 2 exported is wanted
Greatly.In the present embodiment, which is located at the top of main decelerating motor 1, output shaft 21 and main decelerating motor
1 output shaft 11 is coaxial arrangement.
There are one Coupling Shaft 9, the Coupling Shaft 9 is defeated with assisted deceleration motor 2 for connection in the hollow shaft of main decelerating motor 1
Shaft is coaxially connected.The company for being connected with the flange of the two is provided between assisted deceleration motor 2 and main decelerating motor 1
Joint chair 8.Assisted deceleration motor 2 is fixed on main decelerating motor 1 by the connecting seat 8.In main decelerating motor 1 and assisted deceleration motor
Brake gear can be equipped on 2, to be braked, after opening brake gear, motor can rotate.In inner sleeve 5 and outside
The limit switch limited for the adjustable height to channel 4 is also provided between casing 3.
The boarding bridge elevating mechanism of present embodiment use process is as follows.
When elevating mechanism drives the channel 4 of connecting bridge normally to lift, by main decelerating motor 1 and assisted deceleration motor 2
Brake gear is opened, and then, so that main decelerating motor 1 is powered and is rotated, the output shaft 11 of the main decelerating motor 1 drives 71 turns of lead screw
It is dynamic, to drive the channel 4 of connecting bridge that can normally move up and down.For example, when main decelerating motor 1 rotates forward, channel 4
Rise, when main decelerating motor 1 inverts, channel 4 declines therewith.After channel 4 lifts in place, main decelerating motor 1 powers off, and makes master
The brake gear of decelerating motor 1 and assisted deceleration motor 2 is closed.
When system, which receives signal, needs fast drop, the brake gear of main decelerating motor 1 and assisted deceleration motor 2 is beaten first
It opens, then main decelerating motor 1 and assisted deceleration motor 2, which are powered, inverts.When lead screw 71 rotating speed close to main decelerating motor 1 maximum
When rotating speed, for example, lead screw 71 rotating speed reached the main decelerating motor 1 maximum (top) speed 80%, at this moment, by main decelerating motor 1
Power-off, but assisted deceleration motor 2 still constantly accelerates in driving lead screw 71.Since main decelerating motor 1 powers off, will not produce
Raw opposing torque hinders the raising of 71 rotating speed of lead screw.
When maximum (top) speed of the rotating speed of lead screw 71 close to assisted deceleration motor 2, which also powers off, this
When assisted deceleration motor 2 its rotating speed will not be prevented to continue raised application opposing torque lead screw 71.In the channel of connecting bridge 4
Dead weight under the action of, lead screw 71 can keep larger speed to continue to decline.The rotating speed of lead screw 71 can be more than that auxiliary subtracts at this time
The maximum (top) speed of speed motor 2.When the slippage in the channel of connecting bridge 4, which has reached fast drop, to be required, main decelerating motor 1 and auxiliary subtract
The brake gear of speed motor 2 is powered is braked simultaneously, and the channel 4 of connecting bridge can be made rapidly to stop, fast to complete
Operation is dropped.
In conclusion the elevating mechanism of the utility model, has the following advantages.
First, continuous fast drop may be implemented in the elevating mechanism of present embodiment, and existing lifting chain-wales and hydraulic pressure drop soon
It is merely able to, using once, be resetted when next time reuses during picking every time, and the elevating mechanism of present embodiment
No this limitation.Secondly, the electromechanical in present embodiment drops affected by environment small soon, is swift in response, compared with the prior art, safety
Property higher.Again, present embodiment is small to the change of former elevating mechanism, can also omit in existing electromechanical connecting bridge for dropping soon
The various complex components such as elevating mechanism hydraulic system, it is simple in structure, substantially reduce cost.
The utility model embodiment also discloses a kind of connecting bridge, further includes stepping on for present embodiment with channel 4
Machine bridge elevating mechanism.
It is particularly shown and described the illustrative embodiments of the utility model above.It should be understood that the utility model
It is not limited to disclosed embodiment, on the contrary, the utility model intention covers included in spirit and scope of the appended claims
Interior various modifications and equivalent arrangements.
