Embodiment Construction
[0031] exist figure 1 and figure 2 Among them, a safety parking and landing system for people under a stacker forklift, including a body mast 1, a fork frame 2, a hydraulic system 3, a steering system 4, a box body 5, a human body infrared detection device 6 and an emergency stop device 7.
[0032] exist image 3 Among them, the vehicle body mast 1 includes a lower beam 103 , two horizontal base plates 101 , two vertical guide arms 102 , two vertical moving bars 118 , and an upper beam 121 . Two horizontal bottom plates 101 are fixed on the left and right sides of the front side of the lower beam 103 , and two vertical guide arms 102 are fixed on the left and right sides of the lower beam 103 top surface. Considering that the length of the two guide arms 102 is relatively long, they are only connected by the lower crossbeam 103, and the stability is insufficient. Therefore, a reinforcing bar 107 is fixed at the middle position of the rear sides of the two guide arms 102, an...

The invention discloses a stacking forklift truck safety stopping and descending system for people getting down, which comprises a truck body door frame, a fork arm carrier, a hydraulic system, an operation driving system, a box body, human body infrared detection devices and an emergency stop device, the human body infrared detection devices are arranged on the two sides of the fork arm carrier, the emergency stop device comprises a rack, a clamping block and an electromagnet for adsorbing the clamping block, the rack is arranged on the truck body door frame, and the clamping block is arranged on the truck body door frame. The clamping block is hinged to the fork arm carrier, at least one trapezoidal bayonet is formed in the side face, close to the rack, of the clamping block, when the clamping block is matched with the rack, the rack applies resistance to the upper inner wall of the trapezoidal bayonet, a first vertically-downward reference line is drawn from the hinge point of the clamping block, the gravity center is located on the side, close to the electromagnet, of the first reference line, and the gravity of the clamping block generates first torque; a second reference line is made from the hinge point of the clamping block to the acting point of the resistance on the lowermost trapezoidal bayonet, the resistance is located on the side, close to the rack, of the second reference line, the resistance generates a second moment, and the first moment and the second moment both enable the clamping block to face the rack and limit the fork arm carrier to move downwards, so that the sudden stop effect is achieved.
Description
technical field [0001] The invention relates to a stacker forklift, in particular to a safety parking system for people under the stacker forklift. Background technique [0002] A stacker forklift generally includes a body gantry, a fork frame, a hydraulic system, a steering system, and a box body. The hydraulic system cooperates with the fork frame to drive the goods up and down, and then cooperates with the steering system to transfer the goods and stack them. [0003] During the use of the stacker forklift, after the cargo and the fork frame are lifted, the operator's sight will be affected. It is difficult for the operator to observe the situation under the fork frame. , it is easy to cause safety accidents. Contents of the invention [0004] The purpose of the present invention is to provide a safety parking system for people under the stacker forklift, through the infrared detection device of the human body and the emergency stop device, when the infrared detection ...
