When the two side plates contact the goods, the four electric telescopic rods are synchronously shortened by using the control panel in the cab and the synchronous controller, so that the two connecting plates can drive the two support plates and the square tube to move downward. When the square tube moves downward and presses the goods, the forklift can be driven to move the goods. In this process, the goods are intercepted by the two side plates and the square tube and will not tip over. Through the provided concave frame and side plates, a protection structure is provided, which can prevent the lifted goods from tipping over and improves the practicality of the anti-tipping forklift.
[0017] (2) The utility model is provided with a tension sensor, a fixed plate and a telescopic column. According to the above operation, when the two forks are inserted into the bottom space of the goods, the hydraulic pump station and the forward and reverse motor are made to work by using the control panel in the cab. The hydraulic pump station can shorten the hydraulic telescopic rod. By pulling the tension sensor and the two telescopic columns through the fixed plate, the lifting frame can be lifted. The tension sensor can measure the combined weight of the lifting frame, the two forks and the goods. When this part of the weight reaches the preset value of the tension sensor, a signal can be sent to the controller, and the controller can make the alarm work at this time. The operator can judge that the goods cannot be lifted by the sound emitted by the alarm. Through the provided tension sensor, fixed plate and telescopic column, it can help the operator know whether the goods can be lifted, which brings guarantee for the continuous use of the anti-tipping forklift.

[0036] Working principle:
[0037] When actually using the anti-tipping forklift, the operator drives the forklift 1 forward. When the two sets of forklift tines 25 are inserted into the space at the bottom of the goods, the hydraulic pump station and the forward and reverse motor 16 are made to work by using the control panel in the cab. The hydraulic pump station can shorten the hydraulic telescopic rod 3. By pulling the tension sensor 4 and the two sets of telescopic columns 27 through the fixing plate 26, the lifting frame 5 can be lifted. The lifting frame 5 can lift the goods by means of the two sets of forklift tines 25. The output end of the forward and reverse motor 16 can drive the bidirectional lead screw 9 to rotate. Since the bidirectional lead screw 9 is in threaded cooperation with the two sets of lead screw sleeves 10, the rotating bidirectional lead screw 9 can push the two sets of lead screw sleeves 10 to approach or move away from each other. When the two sets of lead screw sleeves 10 approach each other, the two sets of lead screw sleeves 10 can make the two sets of side plates 8 approach each other through the two sets of socket plates 11. In this process, the two sets of support plates 18 approach each other, and the two sets of limit plates 21 and the square tube 19 will stretch the four sets of telescopic springs 22. When the two sets of side plates 8 contact the goods, the four sets of electric telescopic rods 13 are synchronously shortened by using the control panel in the cab and the synchronous controller, so that the two sets of connecting plates 14 can drive the two sets of support plates 18 and the square tube 19 to move downward. When the square tube 19 moves downward to press the goods, the forklift 1 can be driven to move the goods. In this process, the goods are intercepted by the two sets of side plates 8 and the square tube 19 and will not tip over. Through the provided concave frame 7 and side plates 8, a protective structure is provided, which can prevent the lifted goods from tipping over, improving the practicality of the use of the anti-tipping forklift. At the same time, according to the above operations, when the two sets of forklift tines 25 are inserted into the space at the bottom of the goods, the hydraulic pump station and the forward and reverse motor 16 are made to work by using the control panel in the cab. The hydraulic pump station can shorten the hydraulic telescopic rod 3. By pulling the tension sensor 4 and the two sets of telescopic columns 27 through the fixing plate 26, the lifting frame 5 can be lifted. The tension sensor 4 can measure the combined weight of the lifting frame 5, the two sets of forklift tines 25 and the goods. When this part of the weight reaches the preset value of the tension sensor 4, a signal can be sent to the controller, and the controller can make the alarm 24 work at this time. The operator can judge that this goods cannot be lifted by the sound emitted by the alarm 24. Through the provided tension sensor 4, fixing plate 26 and telescopic columns 27, it can help the operator know whether the goods can be lifted, bringing guarantee for the continuous use of the anti-tipping forklift.
