Description

Technical Field

[0001] The utility model relates to the field of cabin door installation, in particular to a cabin door installation hanger. Background Art

[0002] Cabin doors are usually used in the cargo hold, cabin, passenger cabin and other parts of the aircraft. The installation and removal of cabin doors usually require special lifting equipment, which is used to ensure the safety and efficiency of the operation process;

[0003] Chinese patent authorization application number: CN202020246199.7 provides a pallet lifting of an aircraft cabin door assembly fixture. The solution is provided with a pallet, a hanging ring, a hook, an aircraft cabin door, a top plate, a movable pulley, a first bevel gear, a second bevel gear, a wire rope, a servo motor, a gear plate and a gear roller. After the aircraft cabin door is placed on the pallet, the servo motor can be started, so that the output shaft of the servo motor can drive the wire rope to be retracted and extended through the first bevel gear, the second bevel gear, the gear plate and the gear roller with labor-saving transmission. At the same time, the movable pulley can reduce the driving force by half, avoiding the problem that the prior art requires the use of special motors with large professional driving force, resulting in high costs.

[0004] Existing cabin door installation hoists have certain drawbacks when in use. First, the fixed structure of the cabin door installation hoist during the lifting process is relatively simple, and most of them can only undertake the lifting of cabin doors of a single batch size. This makes it impossible to easily adjust when lifting cabin doors of different sizes, resulting in a decrease in the cabin door lifting and positioning effect. To this end, we propose a cabin door installation hoist. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a cabin door installation hoist. By arranging a movable rod and an adjustment component, when the device needs to position and hoist cabin doors of different specifications, starting the adjustment component can drive a pair of movable blocks to adjust and drive the clamping parts to move in relative directions, which can conveniently move and position the cabin doors of different specifications, and when the clamping parts contact the cabin door, the anti-slip pad cooperates with the force generated by the movable rod to perform secondary positioning of the cabin door, which can conveniently adjust a distance within a smaller range, and can position the cabin door more stably, so that the cabin door can be more stable during installation and hoisting, thereby improving the positioning effect of the cabin door installation hoist.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A cabin door installation hanger comprises a main body mechanism, a connecting mechanism is installed on the upper end of the main body mechanism, and a positioning mechanism is slidably connected to the outer end of the connecting mechanism;

[0008] The positioning mechanism includes a clamping piece, which is symmetrically distributed. The inner ends of the clamping pieces are movably connected to anti-slip pads, the rear ends of the anti-slip pads are installed with a movable rod, the outer ends of the movable rods are sleeved with a reset component, and the rear of the reset component is movably connected to an adjustment component.

[0009] The positioning effect of the cabin door installation hanger is improved by installing the movable rod and the adjustment component.

[0010] Furthermore, a movable groove is formed at the outer end of the reset component, and the movable groove is located at the inner end of the clamping member.

[0011] By installing the reset assembly, the movable rod can drive the anti-drop pad to move to different positions, thereby achieving a secondary positioning effect.

[0012] Furthermore, the outer end of the reset assembly is sleeved with symmetrically distributed moving blocks, and the rear ends of the moving blocks are each equipped with a sliding block.

[0013] By installing the moving block, the moving block can form a connecting structure at the outer end of the clamping member, making the connection between the clamping member and the adjustment component convenient.

[0014] Furthermore, the main body mechanism includes a movable frame, a reinforcement frame is installed on the upper end of the movable frame, and a plurality of reinforcement seats are installed on the upper end of the reinforcement frame.

[0015] By installing the reinforcement seat, the reinforcement seat can form a connection structure at the outer end of the lifting frame, so that the connection between the lifting frame and the reinforcement frame is stable.

[0016] Furthermore, a lifting frame is installed on the upper end of the reinforcement seat, the inner end of the lifting frame is hingedly connected to a connecting shaft, and the upper part of the connecting shaft is movably connected to a receiving shaft.

[0017] By installing the connecting shaft, the stability of the lifting frame structure during use is improved.

[0018] Furthermore, a push frame is installed on the upper end of the receiving shaft, and a hydraulic component is installed on the upper end of the push frame.

[0019] By installing the connecting shaft, the installation hoist can drive the cabin door to be lifted and lowered.

[0020] Furthermore, a connecting platform is installed on the upper end of the hydraulic component, a driving frame is installed on the upper end of the connecting platform, the inner end of the driving frame is rotatably connected to a driving component, the outer end of the driving component is sleeved with a guide block, and a connecting arm is installed at the front end of the guide block.

[0021] By installing the guide block and the connecting arm, the convenience of hoisting and adjusting the installation sling is further improved.

[0022] Furthermore, a sliding block is installed at the rear end of the other side of the connecting arm away from the guide block, and the outer end of the sliding block is slidably connected to a sliding groove frame.

[0023] By installing the slide bracket, the connecting arm can be prevented from tipping over when it is raised or lowered.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. By providing a movable rod and an adjustment assembly, when the device needs to position and hoist cabin doors of different specifications, activating the adjustment assembly can drive a pair of movable blocks to adjust and drive the clamping parts to move in opposite directions, which can conveniently move and position cabin doors of different specifications. When the clamping parts contact the cabin door, the anti-drop pad cooperates with the force generated by the movable rod to perform secondary positioning of the cabin door. It can conveniently adjust a small distance, can position the cabin door more stably, make the cabin door more stable during installation and hoisting, and improve the positioning effect of the cabin door installation hoist.

[0026] 2. A reset assembly, consisting of an elastic ring and a guide ring, is provided. It adjusts in tandem with the movement of the active rod. Once the active rod and the anti-slip pad stop positioning the external cabin door, the reset assembly allows the active rod to reset and adjust, allowing the active rod to move the anti-slip pad to a different position, thereby achieving a secondary positioning effect.

[0027] 3. By setting the guide block and the connecting arm, when the lifting frame is lifted to a certain position, the drive assembly composed of the motor and the screw is started to adjust the position of the guide block, and the guide block drives the connecting arm and the external cabin door to adjust the height again, so that the device can be lifted and moved again, which is convenient for adjustment and installation, and further improves the convenience of lifting and adjustment of the installation sling.
