DETAILED DESCRIPTION

[0019] In order to make those skilled in the art can better understand the utility model, the utility model technical scheme is further illustrated below in connection with the drawings and examples.

[0020] Embodiment 1: as shown in Figures 1-4 The utility model discloses a positioning equipment of unpowered equipment, including tow bar body 1, the connecting ring 11 is installed to tow bar body 1 tip, the U-shaped plate 13 is installed to tow bar body 1 front end, the symmetrical installation of gyro wheel 14 has been installed to the both sides of U-shaped plate 13, the symmetrical installation of positioning mechanism has been installed to the inside of U-shaped plate 13, and positioning mechanism includes the first sprocket 15 of U-shaped plate 13 rotation connection, and the first sprocket 15 screw thread connection has the threaded rod 16, and the positioner 17 is fixedly installed to threaded rod 16, and the limit plate 18 is installed to one end of threaded rod 16, and the limit frame 19 of limit plate 18 sliding connection is fixedly installed to U-shaped plate 13, and two first sprocket 15 transmission has the transmission mechanism, and the drive motor 20 of transmission mechanism transmission connection is installed to the side of U-shaped plate 13 close to tow bar body 1.

[0021] When connecting ring 11 is connected with the power car and moves the whole equipment, the power of power car cooperates two gyro wheels 14 and moves, when U-shaped plate 13 moves to the front wheel of aircraft, will positioner 17 with the jack of front wheel alignment, then through transmission mechanism drive first sprocket 15 rotation, because threaded rod 16 is screw thread connection with first sprocket 15, and limit plate 18 fixedly installed with threaded rod 16 and limit frame 19 sliding connection, so threaded rod 16 will drive positioner 17 and extend and insert into the jack of aircraft front wheel, after positioning, can drive tow bar body 1 and aircraft movement through power car.

[0022] Transmission mechanism includes the first taper tooth 21 of drive motor 20 transmission connection, and the transmission shaft 22 is rotatably installed to the inside of U-shaped plate 13, and the second taper tooth 23 of first taper tooth 21 meshing is fixedly installed to the middle part of transmission shaft 22, and the second sprocket 24 is fixedly installed to both ends of transmission shaft 22, and the chain 25 of two second sprocket 24 transmission connection is respectively with two first sprocket 15.

[0023] When drive motor 20 drive first taper tooth 21 rotation, will rotate through the second taper tooth 23 of meshing, further drive transmission shaft 22 and two second sprocket 24 rotation, when second sprocket 24 rotation, will drive chain 25 and first sprocket 15 rotation, like this will drive threaded rod 16 back and forth movement.

[0024] The utility model discloses through drive motor drive first sprocket rotation, cooperate and drive threaded rod and positioner of transmission connection and extend and insert into the jack of aircraft's front wheel, not only avoid the tiredness of artificial connection, also improve work efficiency, convenient and fast operation.

[0025] Embodiment 2: on the basis of embodiment 1, make further improvement, and four installation grooves are evenly set up to positioner 17, and the first spring 26 is installed to installation groove inside, and the abutment block 27 of sliding connection is installed to installation groove inside, and the inclined plane is set up to both sides of abutment block 27, and the protection cylinder 28 is installed to U-shaped plate 13.

[0026] The positioner 17 is located inside the protection cylinder 28 in the initial state, at this time the abutting block 27 is partially located inside the mounting groove and abuts against the inside of the protection cylinder 28, and the above state is the unused state, thereby the protection cylinder 28 plays a protective role on the positioner 17, when the positioner 17 needs to be connected with the front wheel of the airplane, the abutting block 27 is driven to move out, thereby the resilience of the first spring 26 makes the abutting block 27 move outwards, when the inclined surface of the abutting block 27 matches the insertion hole of the front wheel of the airplane, the abutting block 27 is subjected to an external force to overcome the resilience of the first spring 26 and return to the inside of the mounting groove until the inner wall of the insertion hole of the front wheel abuts against the outside of the abutting block 27, the abutting block 27 stops retracting, thereby continuously driving the positioner 17 to move into the insertion hole until it cannot move, in this way, the elastic effect of the abutting block 27 can improve the fitting rate of the positioner 17 with different airplanes, and the elastic effect of the abutting block 27 and the first spring 26 can play a buffering role when the power vehicle drives the positioner 17 and the airplane to move;

[0027] When the traction is released, the positioner 17 is driven to move towards the protection cylinder 28, thereby making the abutting block 27 move away from the insertion hole and enter the inside of the protection cylinder 28.

[0028] The transmission shaft 22 is symmetrically provided with the third conical teeth 29, the U-shaped plate 13 is slidably connected with the mounting plate 30, the mounting plate 30 is fixedly provided with the mounting seat 31 which is rotationally connected with the roller 14, the U-shaped plate 13 is provided with the sliding groove 32 which is slidably connected with the mounting plate 30, and the sliding groove 32 is rotationally provided with the second threaded rod 33 which is threadedly connected with the mounting plate 30, and the upper end of the second threaded rod 33 is provided with the fourth conical teeth 34 which are engaged with the third conical teeth 29.

[0029] When the transmission shaft 22 rotates, the third conical teeth 29 are driven to rotate, thereby driving the fourth conical teeth 34 and the second threaded rod 33 to rotate, when the transmission shaft 22 rotates forward to drive the positioner 17 to extend into the insertion hole, the third conical teeth 29 drive the second threaded rod 33 to rotate forward, thereby driving the mounting plate 30 which is slidably connected with the U-shaped plate 13 to move upwards and away from the ground, in this way, it is convenient for the power vehicle to drive the traction rod and the airplane to move, when the traction is released, the transmission shaft 22 reversely rotates to drive the positioner 17 to extend into the inside of the protection cylinder 28, thereby the second threaded rod 33 reversely rotates to drive the mounting plate 30 to move downwards until the mounting plate 30 abuts against the sliding groove 32, thereby making the roller 14 abut against the ground.

[0030] The abutting block 27 is made of rubber material. The rubber material of the abutting block 27 can be flexibly contacted with the insertion hole, thereby improving the protection effect on the insertion hole.

[0031] The auxiliary placing rod 35 is installed at the front end of the drawbar rod body 1. The auxiliary placing rod 35 is stably placed in cooperation with the two rollers 15 when the drawbar rod is not used, and the limiting frame 19 is provided with an observation slot, which facilitates observation of the position of the limiting plate 18 to ensure that the positioner 17 is connected with the jack.

[0032] The above embodiment only illustrates the principle and effect of the present application, and is not used to limit the present application. Any person skilled in the art can modify or change the above embodiment without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed by the present application should be covered by the claims of the present application.
