Description

Technical Field

[0001] The utility model relates to the technical field of freight handling equipment, in particular to an AGV forklift with a cargo separation detection device. Background Art

[0002] AGV forklifts include pallet forklift AGV, wide-leg stacker AGV, narrow stacker AGV, and footless stacker AGV. They are used for the logistics turnover of stacked pallet goods and are composed of a hydraulic lifting system, a differential drive system, a PLC control system, a guidance system, a communication system, a warning system, an operating system, and a power supply. They are programmable wireless dispatchable automatic guided vehicles that integrate hydraulic lifting and PLC control. This product uses electromagnetic induction as a navigation method to assist RFID identification and can run on complex paths and multi-site reliable tracking. The main drive adopts a self-developed differential servo motor drive and is equipped with a high-precision angle steering servo, which makes the whole vehicle respond quickly and accurately. The independent hydraulic lifting system assists the high-precision displacement sensor so that the forklift can stop at any position within its lifting range, greatly improving the flexibility of loading and the position accuracy of lifting.

[0003] The existing AGV forklift with cargo detachment detection device has the following defects: when the AGV forklift is carrying cargo, the connection between the AGV forklift and the cargo may be accidentally detached, resulting in cargo damage or safety accidents. At the same time, when the cargo on the AGV forklift falls off, it is not possible to promptly detect and alert the relevant technical personnel, which may easily cause cargo damage or safety accidents, thereby reducing the use effect of the AGV forklift cargo detachment detection device and increasing the safety hazards of the AGV forklift.

[0004] Therefore, it is necessary to develop an AGV forklift with a cargo detachment detection device. Utility Model Content

[0024] A fork seat 4 is installed above the base frame 3, and the lower outer wall of the fork seat 4 is slidably connected to the inner wall of the groove 301. The fork seat 4 is slidably set in the groove 301 on the base frame 3, so that the fork seat 4 is in the groove 301 in the reset state. A mounting groove 401 is opened on one side of the surface of the fork seat 4, and a pressure sensor 402 is installed at the center of the inner bottom end of the mounting groove 401. A bearing plate 403 is installed above the inner top of the mounting groove 401, and the outer wall of the bearing plate 403 is slidably connected to the inner wall of the mounting groove 401. Mounting holes 404 are opened on both sides of the lower surface of the fork seat 4, and columns 405 are set on both sides of the bottom of the bearing plate 403. The outer wall of the column 405 is slidably connected to the inner wall of the mounting hole 404, and the bearing plate 403 is slidably arranged in the mounting hole 404 on the fork seat 4 by four groups of columns 405, so that the bearing plate 403 can move vertically up and down on the fork seat 4, and the nut 406 is threadedly connected to the lower part of the outer wall of the column 405, and a spring 407 is arranged on the upper part of the outer wall of the column 405. The spring 407 is located inside the mounting groove 401, and the bearing plate 403 is slidably arranged in the mounting hole 404 on the fork seat 4 by four groups of columns 405, so that the bearing plate 403 can move vertically up and down on the fork seat 4, and the nut 406 is threadedly connected to the lower part of the outer wall of the column 405. The spring 407 is located inside the mounting groove 401. The thread connection is arranged below the outer wall of the column 405, and the spring 407 is arranged above the outer wall of the column 405, so that after the nut 406 is installed, the load-bearing plate 403 can be limited to prevent the load-bearing plate 403 from being separated from the fork seat 4. At the same time, the spring 407 has an elastic support function, so that the spring 407 can elastically support the load-bearing plate 403. By installing the pressure sensor 402 in the installation groove 401 on the fork seat 4, the fork seat 4 is reset in the groove 301 on the bottom frame 3, and then the goods are carried normally. When the goods are moved to the load-bearing plate 403, the load-bearing plate 403 will be affected by the weight of the goods. The pressure moves downward until it contacts the pressure sensor 402. When the pressure sensor 402 contacts the normal pressure, it will not be fed back to the sound and light alarm 201 and the buzzer 202. The sound and light alarm 201, the buzzer 202 and the pressure sensor 402 can be set and connected to the signal of the control console on the AGV forklift in the background. When the goods fall off and the pressure sensor 402 detects that the pressure is abnormal, it will be fed back to the sound and light alarm 201 and the buzzer 202 for alarm processing, so that the surrounding relevant technical personnel can be quickly informed to avoid the situation where the goods fall off and cause harm to the relevant technical personnel.

[0025] Working principle: When using the utility model, an audible and visual alarm 201 is set on the top of the forklift lifting frame 2 on the forklift 1, and a buzzer 202 is set on the end surface of the audible and visual alarm 201, so that the audible and visual alarm 201 and the buzzer 202 can take danger warnings to the surrounding relevant technical personnel to ensure their safe work. By setting a slope 303 on one side of the bottom frame 3 on the forklift lifting frame 2, it is convenient to unload or load goods from the slope 303, and by setting the fork seat 4 in a sliding manner in the groove 301 on the bottom frame 3, the fork seat 4 is in the groove 301 in the reset state. By slidingly arranging the bearing plate 403 in the mounting holes 404 on the fork seat 4 by four groups of upright posts 405, the bearing plate 403 can be vertically moved up and down on the fork seat 4. By threadingly arranging the nut 406 below the outer wall of the upright post 405 and arranging the spring 407 above the outer wall of the upright post 405, after the nut 406 is installed, the bearing plate 403 can be limited to prevent the bearing plate 403 from being separated from the fork seat 4. At the same time, the spring 407 has the function of elastic support, so that the spring 407 can support the bearing plate 403. 3 adopts elastic support treatment, by installing the pressure sensor 402 in the installation groove 401 on the fork seat 4, the fork seat 4 is reset in the groove 301 on the bottom frame 3, and then the goods are carried normally. When the goods are moved to the load-bearing plate 403, the load-bearing plate 403 will move down under the weight pressure of the goods until it contacts the pressure sensor 402. When the pressure sensor 402 contacts the normal pressure, it will not be fed back to the sound and light alarm 201 and the buzzer 202. The sound and light alarm 201, the buzzer 202 and the pressure sensor 402 can be used to control the AGV fork in the background. The control console on the vehicle is set and the signal is connected. When the cargo detaches and falls, the pressure sensor 402 detects that the pressure is in an abnormal state, and then feeds back to the sound and light alarm 201 and the buzzer 202 for alarm processing, so that the surrounding relevant technical personnel can quickly be informed to prevent the cargo from detaching and falling and causing harm to the relevant technical personnel. The cargo detachment detection processing is realized for the AGV forklift. At the same time, the anti-detachment detection processing for the AGV forklift can improve the stability and safety of the transportation process, and effectively improve the use effect of the AGV forklift.
