Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically to a mechanical error-proofing mechanism. Background Technology

[0002] Currently, the elevators in lithium battery filling equipment typically have a mechanical anti-mistake mechanism at the inlet where they connect to the discharge end of the material conveyor. This mechanism usually consists of a blocking block, a cam structure that works with the blocking block, and a cylinder that works with the cam structure. When the elevator car is not in the working position, the cylinder, via the cam structure, moves the blocking block upwards to block the pallets on the material conveyor. This prevents the material conveyor from transporting pallets to the elevator, avoiding situations where pallets are not accurately delivered to the elevator car or fall off. When the elevator car reaches the working position, the cylinder, via the cam structure, moves the blocking block downwards, so that the blocking block no longer blocks the pallets on the material conveyor, allowing the material conveyor to transport the pallets onto the elevator car.

[0003] The aforementioned mechanical error-proofing mechanism uses a cylinder, which is costly and prone to failure, thus causing the mechanical error-proofing mechanism to fail and failing to meet usage requirements. Utility Model Content

[0028] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0029] Please refer to Figures 1 to 3An embodiment of this utility model provides a mechanical anti-foolproof mechanism, including a mounting beam 10, a blocking block 20, a connecting shaft 30, an elastic element 40, a rotating arm 70, and a first rolling element 100.

[0030] Mounting beam 10 is used to install on the frame of the hoist. Block 20 is located above mounting beam 10. Connecting shaft 30 passes through mounting beam 10. In this embodiment, mounting beam 10 has a through hole at its top and a mounting groove 11 at its bottom. The through hole communicates with the mounting groove 11. Connecting shaft 30 passes through the through hole and the mounting groove 11. The mounting groove 11 reduces the weight of mounting beam 10, thereby reducing the weight of the mechanical error-proofing mechanism. One end of connecting shaft 30 is located above mounting beam 10 and connected to block 20. The other end of connecting shaft 30 is located below mounting beam 10 and has an L-shaped connecting block 50. A second rolling element 60 is located on one side of connecting block 50. Connecting shaft 30 can move up and down relative to mounting beam 10. The up and down movement of connecting shaft 30 can drive the connecting block 50, the second rolling element 60, and block 20 to move up and down. Elastic element 40 is located between block 20 and mounting beam 10. The bottom end of the mounting beam 10 has a mounting block 80 on one side of the connecting block 50, and a mounting shaft 81 on one side of the mounting block 80. The rotating arm 70 is rotatably sleeved on the outer periphery of the mounting shaft 81. One end of the rotating arm 70 is located on the side of the second rolling element 60 away from the mounting block 80 and above the second rolling element 60, and the other end of the rotating arm 70 is located on the side of the mounting block 80 away from the second rolling element 60. The bottom end of the rotating arm 70 cooperates with the second rolling element 60. In this embodiment, the bottom end of the rotating arm 70 has an inclined surface 71, which cooperates with the second rolling element 60. One end of the inclined surface 71 is close to the mounting shaft 81, and the other end of the inclined surface 71 is connected to one end of the rotating arm 70 by an arc transition. The first rolling element 100 corresponds to the other end of the rotating arm 70. The first rolling element 100 is used to be installed on the car of the hoist and is used to push the other end of the rotating arm 70 upward.

[0031] With the above structure, in practical application, the mounting beam 10 is installed on the frame of the hoist, and the first rolling element 100 is installed on the car of the hoist. In the initial state, as shown... Figure 3As shown, the blocking block 20 is higher than the bottom of the pallet on the logistics roller conveyor, so as to block the pallet located on the logistics roller conveyor. When the elevator car is moving upward, the first rolling element 100 can move upward synchronously with the car. When the first rolling element 100 touches the other end of the rotating arm 70, as the car continues to move upward, the first rolling element 100 can push the other end of the rotating arm 70 upward, so that the rotating arm 70 can rotate counterclockwise around the axis of the mounting shaft 81. During the rotation, under the action of the inclined surface 71 of the rotating arm 70 and the second rolling element 60, the rotating arm 70 can drive the second rolling element 60, the connecting block 50, and the connecting shaft 30 to move downward, thereby driving the blocking block 20 to move downward until the car reaches the working position. At this time, the second rolling element 60, the connecting block 50, the connecting shaft 30, and the blocking block 20 all reach the predetermined position, and the elastic element 40 is compressed, such as Figure 4 As shown, the blocking block 20 is lower than the bottom of the pallet, so the blocking block 20 no longer obstructs the pallet, and the pallet can be transported to the elevator car via the logistics roller conveyor. After the pallet is on the car, the elevator car moves downward, and the first rolling element 100 moves downward synchronously with the car. During the downward movement of the car, the first rolling element 100 disengages from the other end of the rotating arm 70. Under the reset action of the elastic element 40, the connecting shaft 30, connecting block 50, and second rolling element 60 can be driven upward to the initial position, thereby driving the blocking block 20 upward to the initial position. In this way, the blocking block 20 can block the next pallet on the logistics roller conveyor. Under the action of the inclined surface 71 of the rotating arm 70 and the second rolling element 60, the second rolling element 60 can drive the rotating arm 70 to rotate clockwise around the axis of the mounting shaft 81 to the initial position. Figure 3 As shown.

[0032] The mechanical error-proof mechanism of this utility model has a simple structure, is easy to install, and occupies little space. It consists of an installation beam 10, a blocking block 20, a connecting shaft 30, an elastic element 40, a first rolling element 100, a second rolling element 60, and a rotating arm 70. The rotation of the rotating arm 70 drives the blocking block 20 to move up and down. Compared with the prior art, it does not require the use of a cylinder, which reduces costs and avoids the failure of the mechanical error-proof mechanism, thus meeting the usage requirements.

[0033] A first linear bearing 12 is provided within the through hole and mounting groove 11. The first linear bearing 12 is sleeved on the outer periphery of the connecting shaft 30, and part of the first linear bearing 12 protrudes from the top of the mounting beam 10. The first linear bearing 12 provides movable support for the connecting shaft 30, improving the smoothness of the vertical movement of the connecting shaft 30.

[0034] The mechanical error-proof mechanism of this utility model also includes a guide shaft 90, which passes through the mounting beam 10. In this embodiment, the top end of the mounting beam 10 is provided with a through hole, which communicates with the mounting groove 11. The guide shaft 90 passes through the mounting groove 11 and the through hole. One end of the guide shaft 90 is located above the mounting beam 10 and connected to the blocking block 20, while the other end of the guide shaft 90 is located below the mounting beam 10. The guide shaft 90 can move up and down relative to the mounting beam 10. The up and down movement of the blocking block 20 can drive the guide shaft 90 to move up and down. The guide shaft 90 plays a guiding role in the up and down movement of the blocking block 20, improving the stability of the up and down movement of the blocking block 20.

[0035] A second linear bearing 13 is provided within the through hole and mounting groove 11. The second linear bearing 13 is sleeved on the outer periphery of the guide shaft 90, and part of the second linear bearing 13 protrudes from the top of the mounting beam 10. The second linear bearing 13 provides movable support for the guide shaft 90, improving the smoothness of the guide shaft 90's up-and-down movement.

[0036] In this embodiment, there are two guide shafts 90, which correspond to the two ends of the blocking block 20, respectively. The connecting shaft 30 is located between the two guide shafts 90 and corresponds to the middle of the blocking block 20. The guide shafts 90 and the connecting shaft 30 are parallel. The number of through holes and the number of second linear bearings 13 correspond to the number of guide shafts 90, which are also two each.

[0037] One end of the connecting shaft 30 is connected to the blocking block 20. Specifically, the bottom end of the blocking block 20 has a first groove corresponding to the connecting shaft 30, and one end of the connecting shaft 30 is inserted into the corresponding first groove. The top end of the blocking block 20 has a first mounting hole 21 communicating with the first groove, and one end of the connecting shaft 30 has a second mounting hole. First fasteners, such as screws, are installed in the first mounting hole 21 and the second mounting hole. One end of the guide shaft 90 is connected to the blocking block 20. Specifically, the bottom end of the blocking block 20 has a second groove corresponding to the guide shaft 90, and one end of the guide shaft 90 is inserted into the corresponding second groove. The top end of the blocking block 20 has a third mounting hole 22 communicating with the second groove, and one end of the guide shaft 90 has a fourth mounting hole. Second fasteners, such as screws, are installed in the third mounting hole 22 and the fourth mounting hole.

[0038] The elastic element 40 is a spring. The elastic element 40 is sleeved on the outer circumference of the connecting shaft 30. Two plastic retaining rings 41 are respectively provided at both ends of the elastic element 40. One plastic retaining ring 41 contacts the bottom end of the blocking block 20, and the other plastic retaining ring 41 contacts the top end of the first linear bearing 12. The two plastic retaining rings 41 facilitate compression of the elastic element 40 by the blocking block 20 during the downward movement of the connecting shaft 30, without damaging the blocking block 20 and the mounting beam 10, thus extending the service life of the blocking block 20 and the mounting beam 10.

[0039] The plastic retaining ring 41 is made of PET (Polyethylene terephthalate) resin. Understandably, it can also be made of other materials.

[0040] Both the first rolling element 100 and the second rolling element 60 are rollers, and these rollers are rubber-coated rollers, meaning they are rollers with their outer surface covered with rubber. Using rubber-coated rollers can prevent damage to the rotating arm 70 and extend the service life of the rotating arm 70.

[0041] Block 20 is a plastic block. Using a plastic block prevents damage to the pallet. The plastic block is made of PET resin, but other materials are also acceptable.

[0042] Combination Figures 5 to 8 As shown, the rotating arm 70 is provided with a mounting hole, and a rotating bushing 72 is fitted around the outer periphery of the mounting shaft 81. The rotating arm 70 is fitted onto the outer periphery of the rotating bushing 72 through the mounting hole. The rotating bushing 72 reduces the friction generated by the rotation of the rotating arm 70, protects the mounting shaft 81, and provides rotational support for the rotating arm 70, thereby improving the stability of the rotation of the rotating arm 70.

[0043] Rotary bushing 72 is an oil-free bushing made of, for example, PET resin.

[0044] In this embodiment, a limiting member 811 is provided at the end of the mounting shaft 81, and a step 812 is provided on the outer peripheral surface of the mounting shaft 81. A rotating bushing 72 is located between the limiting member 811 and the step 812. The rotating bushing 72 is a T-shaped bushing, comprising a vertical portion 721 and a horizontal portion 722 fitted around the outer periphery of the mounting shaft 81. One end of the vertical portion 721 contacts the limiting member 811, and the other end of the vertical portion 721 is connected to the horizontal portion 722. The horizontal portion 722 contacts the step 812. A rotating arm 70 is fitted around the outer periphery of the vertical portion 721. One side of the rotating arm 70 contacts the limiting member 811, and the other side of the rotating arm 70 contacts the horizontal portion 722. The limiting member 811 and the step 812 limit the rotation of the bushing 72, preventing it from detaching from the mounting shaft 81. The limiting member 811 and the horizontal part 722 set up play a limiting role on the rotating arm 70, preventing the rotating arm 70 from disengaging from the rotating bushing 72.
