Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. The specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting.

As shown in fig. 1 to 2, a push rod driving device of an unmanned engineering machine includes a push rod 1, a motor 13, a speed reducer 14, a small bevel gear 10, a large bevel gear 9, and a movable swing arm 4. The push rod 1 is connected to a push rod base 3 of the construction machine and can move back and forth with a push rod rotation center shaft 2 as a fulcrum, thereby controlling the forward and backward movement of the construction machine.

The motor 13 and the speed reducer 14 are fixed into a whole through screws and are arranged in a motor box consisting of the motor upper shell 12 and the motor bottom shell 15; the motor 13 is connected with a controller, and the controller can be triggered by a sensor, a limit switch and the like, so that the working condition of the motor 13 is controlled; the output end of the speed reducer 14 is fixedly connected with the small bevel gear 10 through a screw, the small bevel gear 10 is meshed with the large bevel gear 9, and the large bevel gear 9 and the small bevel gear 10 are arranged in a gear box formed by an upper shell 8 and a bottom shell 11 of the gear box; in a specific embodiment, the transmission ratio of the speed reducer is 1:20, the transmission ratio of the two bevel gears is 1:3, and the transmission ratio of the whole device is 1: 60.

Big bevel gear 9 and activity swing arm 4's bottom fixed connection, the top of activity swing arm 4 is equipped with square spacing groove, and square spacing inslot interpolation is equipped with U type pull piece 6, and U type pull piece 6 can remove in square spacing inslot, still is provided with holding screw 5 that is used for fixed U type pull piece 6 on the square spacing groove, and is concrete, and holding screw 5 can be for the hand screws up the holding screw. The motor box and the gear box are connected together by a shell connecting sheet 17, and are fixedly connected on the fixed seat 16.

Two limit switches 7 are arranged on the outer wall of the upper gear box shell 8, and the limit switches 7 are distributed on two sides of the movable swing arm 4, so that the limit on the front-back swing amplitude of the push rod 1 is realized. The principle is as follows: when the movable swing arm 4 swings to a limit angle, one side can press and trigger the limit switch 7, the limit switch 7 transmits a signal to the controller, and the controller controls the stopping and reverse rotation of the motor 13.

When in use, the device is arranged on the side surface of the push rod. When the automatic control device is in an automatic driving mode, the U-shaped drawing block 6 is aligned to the push rod 1 and pushes the U-shaped drawing block 6 until the U-shaped groove of the U-shaped drawing block 6 completely clamps the push rod 1, the position of the U-shaped drawing block 6 is fixed by the set screw 5, the whole transmission linkage process from the motor 13 to the push rod 1 is realized, the motor 13 is controlled to be electrified and steered at the moment, the forward and backward swinging of the push rod 1 can be controlled, and the automatic control mode is realized. When the vehicle is in a manned driving mode, the set screw 5 is loosened firstly, the U-shaped drawing block 6 is drawn out of the square limiting groove until the push rod 1 exits from the U-shaped groove of the U-shaped drawing block 6, the set screw 5 is tightened for limiting, the separation process of the motor 13 and the push rod 1 is realized, and the push rod is operated by hands at the moment, so that the influence of resistance of the motor, the speed reducer, the gear box and the like cannot be caused.
