Description

Technical Field

[0001] This utility model belongs to the technical field of electric pallet trucks, specifically relating to a stable anti-tipping structure for the base of an electric pallet truck. Background Technology

[0002] Electric pallet trucks are logistics handling equipment used for moving goods. They are powered by batteries and motors, with gear transmission driving the vehicle's movement. Lifting of the pallet is achieved using a DC motor and hydraulic transmission, which moves cylinders up and down to lift the pallet and cargo. Because both movement and lifting are electric, and the vehicle is a stand-up driving type with steering levers, it features labor-saving, high efficiency, smooth cargo handling, simple operation, safety, reliability, low noise, and no pollution.

[0003] Problems with existing technology:

[0004] When electric pallet trucks move items, the items may tilt or be damaged due to road conditions or a shift in the center of gravity. Utility Model Content

[0005] The purpose of this utility model is to provide a stable and anti-tipping structure for the base of an electric pallet truck, which can solve the problem that when an electric pallet truck is transporting items, the items may tilt during the transport process due to road conditions or center of gravity shift, thus causing damage to the items.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] This utility model provides a stable and anti-tipping structure for the base of an electric transport vehicle, including a base plate. The base plate has a support mechanism and a torsion mechanism on its side. The support mechanism includes a movable column and a first rotating shaft. A side baffle is fixed on the upper side of the movable column. A first rotating block is sleeved on the movable column and is located between two rotating support plates. A first rotating shaft is fixed on the first rotating block. The two sides of the first rotating shaft are rotatably engaged with the two rotating support plates. A first universal wheel is provided on the lower side of the movable column. A second spring is sleeved on the movable column. The upper side of the second spring is fixed to the bottom surface of the first rotating block, and the lower side of the second spring is connected to the first universal wheel.

[0008] The movable column is provided with a reverse thrust mechanism, which includes a lower pressure plate and a sliding sleeve. The upper side of the lower pressure plate is movably engaged with a fixed plate, and the fixed plate is fixed with a side baffle. The sliding sleeve is sleeved on the sliding column and is hinged to the reverse thrust plate. The reverse thrust plate is movably engaged with the lower pressure plate. A first spring is sleeved on the movable column. The lower side of the first spring is fixed with a first rotating block, and the upper side of the first spring is fixed with the bottom surface of the sliding sleeve.

[0009] The above-mentioned electric pallet truck base stabilization and anti-tipping structure, when the base plate is inserted into the bottom tray of the item, causes the tray to push the inner locking plate. The inner locking plate drives the torsion plate and inner sleeve shaft to rotate, thereby rotating the torsion spring and generating torsional force. At the same time, the brake pin on the torsion plate is rotated, and the brake pin slides down and disengages from the positioning groove and presses down on the fourth spring. Then, as the base plate continues to be inserted, the inner locking plate is released from the push, and the torsion spring drives the torsion plate and the inner locking plate to reset and rotate. The torsion plate drives the brake pin to reset and rotate to the positioning groove, thereby causing the fourth spring to pull the brake upward and slide into the positioning groove to form a positioning brake. At the same time, the torsion plate also drives the inner locking plate to rotate between the two locking plates, thereby causing the two locking plates to form upper and lower surface traps on the inner locking plate, and at the same time providing support for the base plate.

[0010] When the electric pallet truck moves and transports items, if the items tip over, it first pushes the side baffle laterally, causing the side baffle to tilt. This causes the lower pressure plate to press down on the reverse push plate, which then pushes the sliding sleeve upward. This causes the sliding sleeve to push the movable column in the opposite direction to keep it upright. This allows the side baffle to provide reverse support to the ground in the direction the items are tipping over, thereby improving the anti-tipping effect.

[0011] Preferably, the push plate is provided with a support mechanism, and the support mechanism includes a sliding column. A second rotating block is sleeved on the sliding column. The second rotating block is hinged to the lower side of the push plate. The second rotating block is located between two rotating support plates. A second rotating shaft is fixed on the second rotating block. The two sides of the second rotating shaft are rotatably engaged with the two rotating support plates. A second rotating block is sleeved on the sliding column and fixed on the second rotating shaft. A second universal wheel is provided on the lower side of the sliding column. A third spring is sleeved on the sliding column. The upper side of the third spring is fixed to the bottom surface of the second rotating block, and the lower side of the third spring is connected to the second universal wheel.

[0012] Preferably, the two rotating support plates are disposed on the side of the base plate, and the two rotating support plates are fixed to the stabilizing plate and the support plate respectively. The support plate is connected to the torsion mechanism, and the torsion mechanism includes a rotating stop plate and an inner sleeve shaft. The rotating stop plate is fixed on the bottom surface of the support plate, and the inner sleeve shaft is sleeved on the support plate and the rotating stop plate.

[0013] Preferably, a torsion spring is sleeved on the inner sleeve shaft, a fixed plate is fixedly mounted on the upper side of the sliding column, the upper side of the torsion spring is fixedly connected to the support plate, and the lower side of the torsion spring is fixedly connected to the fixed plate.

[0014] Preferably, a brake pin is provided on the lower side of the inner sleeve shaft, the brake pin is sleeved on the torsion plate, the torsion plate is located below the rotating disc, the torsion plate is fixed on the lower side of the inner sleeve shaft, and the brake pin matches the positioning groove formed on the bottom surface of the rotating disc.

[0015] Preferably, a fourth spring is sleeved on the brake column, a fixing plate is fixed to the lower side of the brake column, the lower side of the fourth spring is fixed to the fixing plate, and the upper side of the fourth spring is fixed to the bottom surface of the torsion plate.

[0016] Preferably, an inner clamping plate is fixedly provided on the torsion plate, and two clamping baffles are provided on one side of the torsion plate. The two clamping baffles are fixedly provided on the side of the base plate, and the two clamping baffles match the inner clamping plate.

[0017] The beneficial effects are:

[0018] 1. This utility model uses the side baffle to push the reverse push plate, which can block the items on the base plate from the side. When the items tilt and tip over, the side baffle is pushed, which in turn drives the lower pressure plate to push the reverse push plate. This can push the movable column and the side baffle in the opposite direction to block the items. This can improve the stress support of the side baffle in the direction of the items tipping over, thereby improving the anti-tipping effect of the structure.

[0019] 2. This utility model, through the cooperation of the torsion mechanism and the fixed clamping mechanism, allows the inner clamping plate to rotate and be misaligned with the tray on the bottom of the item when the base plate lifts and moves the item. After the movement, the inner clamping plate can automatically return to the two clamping plates to form a clamping mechanism by the drive of the torsion spring and the fourth spring. In this way, when the base plate is tilted by force, the inner clamping plate and the support mechanism are connected, thereby improving the support of the base plate and improving the handling effect of the electric pallet truck.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1 As shown, an electric pallet truck base stabilization and anti-tipping structure includes a base plate 5. The side of the base plate 5 is provided with a support mechanism and a torsion mechanism. The support mechanism includes a movable column 6 and a first rotating shaft 8. A side baffle 3 is fixed on the upper side of the movable column 6. A first rotating block 7 is sleeved on the movable column 6. The first rotating block 7 is located between two rotating support plates 18. A first rotating shaft 8 is fixed on the first rotating block 7. The two sides of the first rotating shaft 8 are rotatably engaged with the two rotating support plates 18. A first universal wheel is provided on the lower side of the movable column 6. A second spring 91 is sleeved on the movable column 6. The upper side of the second spring 91 is fixed to the bottom surface of the first rotating block 7. The lower side of the second spring 91 is connected to the first universal wheel.

[0027] The movable column 6 is provided with a reverse thrust mechanism, which includes a lower pressure plate 12 and a sliding sleeve 10. The upper side of the lower pressure plate 12 is movably engaged with the fixed plate 13. The fixed plate 13 is fixed with the side baffle 3. The sliding sleeve 10 is sleeved on the sliding column 17. The sliding sleeve 10 is hinged with the reverse thrust plate 11. The reverse thrust plate 11 is movably engaged with the lower pressure plate 12. A first spring 9 is sleeved on the movable column 6. The lower side of the first spring 9 is fixed with the first rotating block 7. The upper side of the first spring 9 is fixed with the bottom surface of the sliding sleeve 10.

[0028] See attached document Figure 2 The push plate 11 is equipped with a support mechanism, which includes a sliding column 17. A second rotating block 14 is sleeved on the sliding column 17. The second rotating block 14 is hinged to the lower side of the push plate 11 and is located between two rotating support plates 18. A second rotating shaft 15 is fixed on the second rotating block 14. The two sides of the second rotating shaft 15 are rotatably engaged with the two rotating support plates 18. The second rotating block 14 is sleeved on the sliding column 17 and fixed on the second rotating shaft 15. A second universal wheel is provided on the lower side of the sliding column 17. A third spring 16 is sleeved on the sliding column 17. The upper side of the third spring 16 is fixed to the bottom surface of the second rotating block 14, and the lower side of the third spring 16 is connected to the second universal wheel. This arrangement can accommodate the vertical adjustment of the base plate 5 and maintain consistency with the first rotating block 7, thereby ensuring the vertical state of the side baffle 3 and providing anti-tipping support for items.

[0029] See attached document Figure 3Two rotating support plates 18 are provided on the side of the base plate 5. The two rotating support plates 18 are fixed to the stabilizing plate 1 and the support plate 2 respectively. The support plate 2 is connected to the torsion mechanism, and the torsion mechanism includes a rotating stop plate 21 and an inner sleeve shaft 22. The rotating stop plate 21 is fixed on the bottom surface of the support plate 2, and the inner sleeve shaft 22 is sleeved on the support plate 2 and the rotating stop plate 21.

[0030] Furthermore, a torsion spring 27 is sleeved on the inner shaft 22, and a fixed plate is fixed on the upper side of the sliding column 17. The upper side of the torsion spring 27 is fixedly connected to the support plate 2, and the lower side of the torsion spring 27 is fixedly connected to the fixed plate. With this arrangement, after the torsion plate 23 is rotated under force, it can be driven by the torsion spring 27 to rotate in the opposite direction and return to its original position, thereby facilitating the braking column 25 to perform positioning braking.

[0031] Furthermore, a brake pin 25 is provided on the lower side of the inner sleeve shaft 22. The brake pin 25 is sleeved on the torsion plate 23, which is located below the rotating disc 21. The torsion plate 23 is fixed on the lower side of the inner sleeve pin. The brake pin 25 matches the positioning groove formed on the bottom surface of the rotating disc 21. After the brake pin 25 is inserted into the positioning groove on the rotating disc 21, the position of the torsion plate 23 and the inner clamping plate 24 is fixed, thereby ensuring that the inner clamping plate 24 is located between the two clamping plates 4. This can form a secondary support for the support mechanism and the base plate 5, thereby improving the connection effect between the anti-tipping support and the base plate 5.

[0032] Furthermore, a fourth spring 26 is fitted onto the brake pin 25, and a fixed plate is fixed to the lower side of the brake pin 25. The lower side of the fourth spring 26 is fixed to the fixed plate, and the upper side of the fourth spring 26 is fixed to the bottom surface of the torsion plate 23. This arrangement allows the brake pin 25 to slide down and disengage from the positioning groove due to the rotation of the torsion plate 23, relying on the elasticity of the fourth spring 26. This facilitates the rotation adjustment of the torsion plate 23. Additionally, the fourth spring 26 can pull the brake pin 25 to automatically spring back into the positioning groove, positioning it when the torsion plate 23 rotates in the opposite direction, thus achieving a positioning effect on the inner clamping plate 24.

[0033] Furthermore, an inner clamping plate 24 is fixed on the torsion plate 23, and two clamping baffles 4 are provided on one side of the torsion plate 23. The two clamping baffles 4 are fixed on the side of the base plate 5. The two clamping baffles 4 match the inner clamping plate 24, so that when the inner clamping plate 24 is located between the two clamping baffles 4, the two clamping baffles 4 form an upper and lower clamping effect on the inner clamping plate 24, thereby providing support for the base plate 5.

[0034] Using the above structure, when the base plate 5 is inserted into the bottom tray of the item, the tray pushes the inner locking plate 24. The inner locking plate 24 drives the torsion plate 23 and the inner sleeve shaft 22 to rotate, thereby rotating the torsion spring 27 and generating a torsional force. At the same time, the brake pin 25 on the torsion plate 23 is rotated, and the brake pin 25 slides down and disengages from the positioning groove and presses down on the fourth spring 26. Then, as the base plate 5 continues to be inserted, the inner locking plate 24 is released from the push, and the torsion spring 27 drives the torsion plate 23 and the inner locking plate 24 to return to their original rotation. This causes the torsion plate 23 to drive the brake pin 25 to return to its original rotation and rotate to the positioning groove. This causes the fourth spring 26 to pull the brake upward and slide into the positioning groove to form a positioning brake. At the same time, the torsion plate 23 also drives the inner locking plate 24 to rotate between the two locking plates 4, thereby causing the two locking plates 4 to form upper and lower surface locking on the inner locking plate 24 and to support the base plate 5.

[0035] When the electric pallet truck moves and transports items, if the items tip over, it first pushes the side baffle 3 laterally, causing the side baffle 3 to tilt. This causes the lower pressure plate 12 to press down on the reverse push plate 11, and the reverse push plate 11 then slides and pushes the sliding sleeve 10 upward, causing the sliding sleeve 10 to push the movable column 6 in the opposite direction to keep it upright. This causes the side baffle 3 to form a reverse support against the ground in the direction of the items tipping over, thereby improving the anti-tipping effect.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
