[0016] An embodiment of a construction engineering aerial work equipment of the present invention is as follows Figure 1-Figure 5 As shown, it includes a gantry 1, a slider 5 is installed on the horizontal beam of the gantry 1 for horizontal guiding movement, a hoist 3 is arranged on the slider 5, and a hanging basket 7 is hoisted on the hoist 3 through a wire rope 4. A first lead screw 6 is rotatably arranged on the gantry 1, the slider 5 is threadedly connected to the first lead screw 6, and a first driving motor that drives the first lead screw 6 to rotate is arranged on the gantry 1, and the translation of the hanging basket is achieved under the action of the first driving motor. An electrical control box 30 is arranged on the hanging basket 7, the first driving motor is connected to the electrical controller box, and the hoist is also connected to the electrical control box.

[0017] A standing area 21 is provided on the bottom plate of the hanging basket 7, and a first supporting rod 14 and a second supporting rod 15 are installed on the side wall of the hanging basket 7 in a horizontally guided manner. A driving mechanism connected to an electrical control box and driving the first supporting rod and the second supporting rod to move relative to or opposite to each other is provided on the hanging basket 7. The driving mechanism includes a second lead screw 11 rotatably provided on the hanging basket, the first support rod 14 and the second support rod 5 are both threadedly connected to the second lead screw 11, and a second driving motor 26 driving the second lead screw to rotate is provided on the hanging basket, and the second driving motor 26 is connected to an electrical control box 30. The hanging basket 7 is provided with a first button 16 connected to the electrical control box for controlling the hanging basket to rise, a second button 17 for controlling the hanging basket to descend, a third button 18 for controlling the second driving motor to rotate forward, and a fourth button 19 for controlling the second driving motor to rotate reversely. The second lead screw has a first thread segment 12 that is threadedly matched with the first support rod and a second thread segment 13 that is threadedly matched with the second support rod. The first thread segment and the second thread segment have opposite rotation directions. A driven gear 20 is arranged between the first thread segment and the second thread segment on the second lead screw, and a driving gear 25 is arranged on the motor shaft of the second drive motor. The first support rod and the second support rod have a relative movement to the station area to protect the working position of the operator (such as Figure 3 ) and move in opposite directions to the farthest idle position (as shown Figure 2 The first supporting rod is provided with a left translation button 23 and a right translation button 24 connected to the electrical control box to control the action of the first driving motor. In this embodiment, the number of the second lead screws is two and they are relatively arranged on the corresponding two sides of the hanging basket.

[0018] A groove 31 is provided on the bottom plate of the hanging basket in the standing area, a pedal 27 is installed in the groove 31, a pressure sensor 28 is provided on the bottom of the groove below the pedal, and the pressure sensor is connected to the electrical control box to send a signal to the electrical control box. A first mounting groove with an opening downward is provided on the pedal, a second mounting groove is provided on the bottom of the groove, a spring 29 is provided between the pedal and the bottom of the groove, one end of the spring is provided in the first mounting groove, and the other end of the spring is provided in the second mounting groove. The pedal and the pressure sensor are provided to ensure that the operator can only translate after standing firmly. When the operator stands on the pedal, the pressure sensor detects the corresponding pressure data and transmits it to the electrical control box. At this time, the third button is pressed again, and the two support rods will move. Otherwise, the third button is directly pressed and the two support rods will not move. It is ensured that the operator is in a stable state before the translation begins, which effectively ensures the safety of the operator.

[0019] The side wall of the hanging basket is provided with a first horizontal guide groove 32 for horizontally guiding the first support rod and a second horizontal guide groove 33 for guiding the second support rod. The side wall portion of the hanging basket between the first horizontal guide groove and the second horizontal guide groove forms a limit structure 34 corresponding to the standing area to ensure that the operator will not be pinched. The first support rod and the second support rod are both provided with a hand grip 22, and the left translation button 23 and the right translation button 24 are arranged on the hand grip on the first support rod. A sliding connection structure is provided between the hanging basket and at least one vertical beam 2 of the gantry, and the vertical beam is provided with a dovetail groove 9 whose length extends in the up-down direction. The sliding connection structure includes a guide block 10 installed in the dovetail groove for upward and downward guidance. A telescopic rod 8 is provided on the hanging basket, and the other end of the telescopic rod 8 is connected to the guide block. It can not only ensure that the hanging basket can be stably translated during the translation process without sudden shaking, but also prevent shaking during the lifting or translation of the hanging basket, thereby ensuring the safety of the operator.

[0020] During use, when lifting is required, the first and second buttons can be directly pressed, which is the usage of the conventional gantry lifting basket. When horizontal movement is required during the operation, the operator needs to stand on the pedal. The pressure sensor under the pedal detects the corresponding pressure signal and transmits it to the electrical control box. At this time, the third button is pressed, and the two support rods move relative to each other to the appropriate position to stop the button. At this time, the operator holds the hand grip of each support rod and presses the left translation button or the right translation button as needed. After moving to the appropriate position and stabilizing, press the fourth button, and the two support rods move back to the idle position. At this time, the foot leaves the pedal and performs the corresponding operation. When the electrical control box does not receive the signal from the pressure sensor, the operator presses any of the third button, the fourth button, the left translation button and the right translation button, and there will be no corresponding action to prevent misoperation.

[0021] In other embodiments of the present invention, the left translation button and the right translation button may also be arranged on the hand grip of the second supporting rod; the left translation button and the right translation button may also be arranged on the hand grip of the first supporting rod and the second supporting rod respectively; the hand grip may not be provided, and the left translation button and the right translation button may be directly provided on the corresponding supporting rod; the spring may not be provided between the pedal and the groove; the dovetail groove may also be replaced by a T-shaped groove; the groove, pedal and pressure sensor may also not be provided while ensuring that the operator can stand firmly.
