[0002] With technological advancements, social and economic development has seen tremendous growth. Automated operations have replaced traditional manual production, and smart logistics has gradually overturned the traditional logistics system. The pursuit of logistics efficiency has given rise to the first generation of automated AGV products. AGV, short for "Automated Guided Vehicle," refers to a transport vehicle equipped with an automated guidance device, such as an electromagnetic or optical one, that follows a prescribed path and features safety protection and various transfer functions.
[0003] However, in practice, people have noticed that when the AGV forklift is moving, the height of the cargo far exceeds the height of the AGV forklift, and the vibration generated when the AGV forklift encounters a pothole during movement will be directly transmitted to the bottom of the cargo, which can easily cause the cargo on the forklift to shake. As the amplitude of the cargo shaking increases, it is easy for the cargo to tip over. In addition, when the uphill slope is large, it is easy for the cargo pallet and the fork to slip, causing the cargo to slide off the fork and cause a safety accident. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0036] See also Figure 1-13 The embodiment of the utility model provides an anti-fall AGV forklift, comprising a frame 1, with a steering wheel and a load-bearing wheel 2 movably connected to both ends of the frame 1, and extension frames 3 symmetrically provided on both sides of the frame 1, the extension frames 3 being located at both ends of the load-bearing wheel 2, and an auxiliary buffer 4 being installed under each of the extension frames 3;
[0037] The frame 1 is fixedly connected to a hydraulic cylinder 10 in a rectangular array. A fork 5 is also provided above the frame 1, and the bottom of the fork 5 is fixedly connected to the end of the hydraulic cylinder 10. The end of the fork 5 is symmetrically provided with a mechanical pop-up mechanism 6.
[0038] In this embodiment, the mechanical pop-up mechanism 6 includes a second fixed frame 61 fixedly connected to the bottom of the fork 5, and the side of the second fixed frame 61 is symmetrically fixedly connected to a limiting frame 63. A pop-up baffle 64 is movably connected between the two limiting frames 63, and the bottom of the pop-up baffle 64 is fixedly connected to a traction rope 66.
[0039] In this embodiment, the bottom of the second fixing frame 61 is movably connected to a guide cam 62, one end of the traction rope 66 is fixedly connected to the pop-up baffle 64, and the other end passes around the bottom of the guide cam 62 and then tilts upward and fixedly connected to the end of the frame 1.
[0040] In this embodiment, the bottom of the limit frame 63 is integrally provided with an L-shaped limit frame, and the side of the limit frame is provided with a compression spring 65, the bottom of the compression spring 65 is clamped with the limit frame, and the top of the compression spring 65 is clamped with the pop-up baffle 64.
[0041] In this embodiment, a through hole 51 corresponding to the pop-up baffle 64 is formed at the end of the fork 5 , and the end of the pop-up baffle 64 passes through the inner side of the through hole 51 .
[0042] In this embodiment, the auxiliary buffer 4 includes a swing bracket 41, and an axle seat 43 is integrally provided above the swing bracket 41. The two sides of the axle seat 43 are movably connected to the first fixing frame 44 through a pin shaft, and the end of the first fixing frame 44 is fixedly connected to the extension frame 3 by bolts.
[0043] In this embodiment, the two ends of the swing bracket 41 are movably connected to the auxiliary wheels 42, and the two ends of the auxiliary wheels 42 are movably connected to the support shaft. The two ends of the support shaft pass through the auxiliary wheels 42 and extend to the two sides of the swing bracket 41, and the two sides of the support shaft are movably connected to the buffer spring 46.
[0044] In this embodiment, both ends of the buffer spring 46 are fixedly connected to a connecting seat 45. The connecting seat 45 on the side close to the swing bracket 41 is movably connected to both ends of the support shaft, and a U-shaped seat 47 is movably connected above the connecting seat 45 on the side away from the swing bracket 41.
[0045] The U-shaped seat 47 is fixedly connected to the extension frame 3 by bolts.
[0046] By adopting the above technical solution, the fork 5 is first pushed into the bottom of the cargo pallet, and then the hydraulic cylinder 10 pushes the fork 5 to move upward. At this time, the compression spring 65 will push the pop-up baffle 64 to move upward. The pop-up baffle 64 passes through the inner side of the through hole 51 and moves upward to block the side of the cargo, preventing the cargo from slipping off the fork 5 due to the tilt of the forklift when going up and down the slope. When the forklift is moving, the extension frame 3 and the auxiliary buffer 4 arranged on both sides can increase the bearing point, and the support range at the bottom is wider. Cooperating with the buffer mechanism in the auxiliary buffer 4, the shaking amplitude of the cargo during movement is reduced to prevent rollover.
[0047] In this embodiment, the pop-up baffle 64 is also movably connected to an auxiliary cam 641 on the side close to the guide cam 62, and the traction rope 66 first passes around the side of the auxiliary cam 641 and then passes around the bottom of the guide cam 62, guiding the traction rope 66 and preventing the traction rope 66 from getting stuck during movement.
[0048] In this embodiment, the end of the pop-up baffle 64 is symmetrically provided with a positioning protrusion, which is inserted into the end of the compression spring 65 away from the limit frame, thereby positioning the compression spring 65 to prevent the end from being offset after being squeezed. In addition, the compression spring 65 can push the pop-up baffle 64 to pop out automatically, without the need for manual operation, thereby reducing labor intensity.
[0049] In this embodiment, the end of the frame 1 is further fixedly connected to a protective shell 7, and the upper part of the protective shell 7 is fixedly connected to a vertical pole 8, the end of the vertical pole 8 is provided with a control screen 9, and the inner side of the protective shell 7 is installed with a control module;
[0050] The control panel 9 is electrically connected to the control module. The worker issues instructions to the control module through the control panel 9, and then the control module controls the actions of various electrical components.
[0051] In this embodiment, an oil storage tank is fixedly connected to the inner side of the protective housing 7, and a hydraulic pump is installed on the side of the oil storage tank. One end of the hydraulic pump is connected to the inner side of the oil storage tank, and the other end of the hydraulic pump is connected to the hydraulic cylinder 10 through an oil pipe. The hydraulic pump sends the hydraulic oil in the oil storage tank into the hydraulic cylinder 10 through the oil pipe, thereby controlling the lifting and lowering of the hydraulic cylinder 10.
[0052] The hydraulic pump is electrically connected to the control module via a wire, and the control panel 9 transmits instructions to the control module, which controls the rotation of the hydraulic pump.
[0053] In this embodiment, the bottom of the frame 1 is further fixedly connected to a reducer 11, the end of the reducer 11 is fixedly connected to a drive motor, and the end of the drive motor is connected to the input shaft of the reducer 11 through a coupling.
[0054] The output shaft of the driving motor drives the reducer 11 to rotate, and the gear set inside the reducer 11 cooperates to reduce the rotation speed of the output shaft of the reducer 11.
[0055] In this embodiment, the output shaft end of the reducer 11 is fixedly connected to a sprocket, and two sprockets are provided, the other of which is fixedly connected to one end of the moving wheel 2, and a transmission chain 12 is sleeved on the outer side of the two sprockets. The reducer 11 drives the moving wheel 2 to rotate through the engagement between the sprocket and the transmission chain 12, thereby realizing the automatic movement of the forklift and further reducing labor intensity.
[0056] The working principle of the utility model is as follows: when in use, the forklift is first moved to the bottom of the cargo pallet, and then the control module is instructed through the control screen 9. The control module controls the hydraulic pump to send the hydraulic oil in the oil storage tank into the hydraulic cylinder 10 through the oil pipe. The hydraulic cylinder 10 pushes the fork 5 to move upward to lift the pallet and the cargo. At the same time, the fork 5 will drive the guide cam 62 to move upward through the second fixed frame 61, thereby reducing the force on the traction rope 66. Then the compression spring 65 pushes the pop-up baffle 64 to move upward, and the pop-up baffle 64 moves to the side of the cargo to prevent the cargo from sliding on the fork 5. Then the fork drives the cargo to move. During the movement, the extension frame 3 and the auxiliary buffer 4 increase The weighing width of the frame 1 is large, and when encountering a pit, the buffer springs 46 at both ends will push the second fixing frame 61 to swing, and the buffer spring 46 uses the buffering and shock-absorbing characteristics to reduce the vibration of the goods when moving, thereby reducing the shaking amplitude of the goods and preventing rollover. After transporting the goods to the designated position, the fork 5 moves downward and pushes the guide cam 62 downward through the second fixing frame 61. Since the end of the traction rope 66 passes around the bottom of the guide cam 62 and is fixedly connected to the frame 1, when the guide cam 62 moves downward, the traction rope 66 will also move downward, so that the other end of the traction rope 6 drives the pop-up baffle 64 to move downward, realizing the automatic pop-up and retraction of the pop-up baffle 64.
