Description

Technical Field

[0001] The utility model belongs to the field of transport traction, and in particular relates to a suspended electromagnetic buffer traction device for an electric tractor. Background Art

[0002] When transporting materials, electric tractors rely on docking with the hopper they're loaded with. When lifting or placing the hopper, the electric tractor must control the corresponding traction device to connect or disconnect with the hopper. With rising labor costs and evolving enterprise technical safety regulations, the connection between electric tractors and hoppers has become more automated.

[0003] A Chinese utility model patent with authorization announcement number CN208585042U discloses an electromagnetic traction device, including a traction assembly, an electromagnet, and a microswitch. One end of the traction assembly is used to connect to a first device, and the electromagnet and microswitch are both installed at the other end of the traction assembly. The electromagnet and the microswitch are electrically connected, and the electromagnet cooperates with a metal part so that when the first device moves, the second device moves, and vice versa. Although the traction device has the characteristics of simple structure, easy use, and can achieve rapid docking, the electromagnet and microswitch on the electromagnetic traction device are exposed to the outside. External dust and rain will accelerate the service life of the electromagnet and microswitch. Moreover, if the electromagnet loses power due to improper operation, the traction assembly can immediately disconnect the metal part, which can easily cause the hopper to detach and cause the material to scatter.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] See also Figure 1-4 As shown, in this embodiment, an electric tractor-mounted electromagnetic buffer traction device is provided, comprising: a traction seat 1, a traction iron block 3, and a connecting frame 13. A traction groove 2 is formed on one side of the traction seat 1, an electromagnet 6 is disposed in the traction groove 2, a micro switch 15 connected to the electromagnet 6 by wires is disposed at the bottom of the traction groove 2, and a protective plate 4 is elastically and rotatably connected to the traction groove 2.

[0031] The traction iron block 3 corresponds to the electromagnet 6, and there are slots 5 on both sides of the traction iron block 3;

[0032] A buffer connection member 14 is provided between the connecting frame 13 and the fifth wheel 1;

[0033] Among them, both sides of the traction groove 2 are equipped with clamping pieces 8 that are engaged with the two clamping slots 5, and both sides of the traction seat 1 are provided with pressing blocks 9 that cooperate with the clamping pieces 8. The connecting frame 13 is connected to the electric tractor, and the traction iron block 3 is connected to the hopper. When the traction iron block 3 is inserted into the traction groove 2, the traction iron block 3 squeezes the microswitch 15. After the microswitch 15 is triggered, the electromagnet 6 is turned on to generate a magnetic field. The traction iron block 3 is attracted to the electromagnet 6 under the action of the magnetic field force, which enables the electric tractor to pull the hopper.

[0034] By arranging the electromagnet 6, micro switch 15 and protective plate 4 in the traction groove 2, the electromagnet 6 can be magnetically connected to the traction iron block 3 in the traction groove 2. When the electromagnet 6 and the traction iron block 3 are out of traction, the protective plate 4 automatically shields and protects the traction groove 2 through elastic force, thereby reducing the situation where the electromagnet 6 and the micro switch 15 are exposed to the outside and affect their service life; by arranging the clamping piece 8 in the traction groove 2, when the traction iron block 3 is inserted into the traction groove 2, the two clamping pieces 8 automatically engage the two clamping slots 5 on the traction iron block 3, and the traction iron block 3 can be fixed on the traction seat 1, thereby reducing the situation where the electromagnet 6 immediately disconnects the traction iron block 3 after power is cut off, causing the hopper to detach and cause material to scatter.

[0035] like Figure 4 As shown, the clamping member 8 of this embodiment includes a fixed groove 801 provided on one side of the traction groove 2, a clamping block 802 disposed in the fixed groove 801 and clamped with the clamping groove 5, a movable plate 803 that rotates and elastically fits in one side of the traction seat 1 and is connected to the clamping block 802, and one side of the pressing block 9 is fixedly connected to one side of the movable plate 803; the side of the clamping block 802 opposite to the traction iron block 3 is provided with a rounded corner;

[0036] like Figure 4 As shown, in this embodiment, chambers 12 connected to the fixed grooves 801 are provided on both sides of the traction seat 1, and a rotating rod 10 is rotatably fitted in the chamber 12. The middle part of the movable plate 803 is mounted on the side of the rotating rod 10, and a first torsion spring 11 is sleeved on the side of the rotating rod 10. The two ends of the first torsion spring 11 are fixedly connected to the movable plate 803 and the chamber 12 respectively.

[0037] When the traction iron block 3 is inserted into the traction groove 2 on the traction seat 1, the clamping block 802 is squeezed back into the fixed groove 801 by the traction iron block 3 through the rounded corners. When the traction iron block 3 is fully inserted into the traction groove 2, the movable plate 803 is reset by the elastic force of the torsion spring 11, driving the clamping block 802 into the clamping groove 5 for clamping, which can fix the traction iron block 3 on the traction seat 1, thereby preventing the traction iron block 3 from being immediately disconnected after the electromagnet 6 is powered off, causing the hopper to detach and cause the material to scatter.

[0038] Press the two pressing blocks 9 at the same time, and the pressing block 9 drives one end of the movable plate 803 to move. The movement of one end of the movable plate 803 drives the other end to move through the rotation of the rotating rod 10. The movement of the other end of the movable plate 803 drives the card block 802 to move out of the card slot 5. At this time, the traction iron block 3 can be pulled out of the traction slot 2.

[0039] like Figure 1 As shown, the buffer connection member 14 of this embodiment includes two fixed plates 1401 fixedly connected to one side of the traction seat 1, a pin 1402 rotatably engaged between the two fixed plates 1401, and a second torsion spring 1403 sleeved around the circumference of the pin 1402. The connecting frame 13 is sleeved on the pin 1402, and the two ends of the second torsion spring 1403 are respectively fixedly connected to the connecting frame 13 and the fixed plate 1401;

[0040] Among them, the second torsion spring 1403 enables the traction seat 1 to recover after rotation, thereby making the connecting frame 13 and the traction seat 1 smoother during movement. At the same time, when the electric tractor and the hopper pull each other to turn, the pin shaft 1402 can ensure that the electric tractor and the hopper behind can complete the turn smoothly, and after the turn is completed, they are quickly returned to the center through the second torsion spring 1403, thereby improving the safety of the traction movement.

[0041] like Figure 3 As shown, a placement groove is provided on the traction groove 2 of this embodiment, a rotating shaft 7 is rotatably fitted in the placement groove, and the protective plate 4 is fixedly connected to the rotating shaft 7; a third torsion spring is sleeved on the circumference of the rotating shaft 7, and the two ends of the third torsion spring are respectively fixedly connected to the protective plate 4 and the placement groove.

[0042] When the traction iron block 3 is inserted into the traction groove 2, the traction iron block 3 squeezes the protective plate 4 and flips it into the placement groove. When the traction iron block 3 moves out of the traction groove 2, the protective plate 4 is reset by the elastic force of the third torsion spring. The protective plate 4 automatically blocks and protects the traction groove 2 by the elastic force, reducing the situation where the electromagnet 6 and the micro switch 15 are exposed to the outside and affect their service life.

[0043] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
