The length direction of the Y-direction screw rod 28 is parallel to the length direction of the Y-direction rail 26. The bottom frame 1 is provided with a plurality of receiving frames 3.

[0052] The application also discloses a method for using the high-efficiency axle transfer system.

[0053] S1, the position of the bottom frame 1 is fixed, and the axle is lifted to the top of the adaptive frame 4;

[0054] S2, the height of the axle is lowered;

[0055] S3, in the process of lowering the axle, the position of the adaptive frame 4 is adjusted according to the activity state of the axle through the first adjusting mechanism and the second adjusting mechanism, and the two ends of the axle are in contact with the inner wall of the supporting groove 6;

[0056] S4, the position of the adaptive frame 4 is moved to a specified position, and the axle is completed;

[0057] S5, the bottom frame 1 drives the adaptive frame 3, the adaptive frame 4 and the axle to move, and the axle is transferred to the bottom of the vehicle body.

[0058] The high-efficiency axle transfer system and the method thereof provided by the application first fix the position of the bottom frame 1, and then lift the axle to the top of the adaptive frame 4; then lower the height of the axle; in the process of lowering the axle, the position of the adaptive frame 4 is adjusted according to the activity state of the axle through the first adjusting mechanism and the second adjusting mechanism, and the two ends of the axle are in contact with the inner wall of the supporting groove 6; then the position of the adaptive frame 4 is moved to a specified position, and the axle is completed; finally, the bottom frame 1 drives the adaptive frame 3, the adaptive frame 4 and the axle to move, and the axle is transferred to the bottom of the vehicle body, and the vehicle body is lowered, so that the vehicle body can be connected with the axle. Since the X-direction and Y-direction positions of the adaptive frame 4 can be appropriately moved, even if the translation and / or lowering speed of the axle during the transfer process is relatively fast (compared with very slow), the axle can be smoothly received through the position adjustment of the adaptive frame 4. Although the application cannot completely receive the axle with severe shaking, compared with the very slow movement of the axle, the axle receiving efficiency can be improved to a certain extent, and the assembly efficiency of the axle and the vehicle body is also improved.

[0059] In actual use, preferably, the base frame 1 has several receiving frames 3, so that multiple axles can be transferred at one time, and the assembly efficiency can be improved. In the embodiment, the number of receiving frames 3 is preferably three. Before actual use, the distance between the support grooves 6 on different receiving frames 3 needs to be adjusted according to the distance of the vehicle axle, for example, the standard axle distance of a semitrailer is 1310, after the positions of adjacent receiving frames 3 are adjusted by the X-direction lead screw 27, the positions of the adjusting frame 25 and the receiving frame 3 remain unchanged during the subsequent receiving and moving of the axle; if it is a special vehicle model, it may also be 1250 or 1400, and the X-direction lead screw 27 needs to be adjusted again; the Y-direction lead screw 28 needs to be adjusted every time during the assembly process, because the position of the axle and the vehicle body is not very accurate, so even if the position of the axle reaches the position below the vehicle body, the receiving frame 3 and the axle still need to be adjusted by the Y-direction lead screw 28, and the axle and the vehicle body can be smoothly connected.

[0060] When receiving the axle, the axle will shake to a certain extent during the lowering process (this process is not particularly fast, so the axle will not shake too much, but it has been accelerated compared to the current very slow lowering of the axle), at this time the worker holds the operating part 15 and also observes the position of the axle, wherein the axle is preferably lifted to a position in the middle of the Y-direction groove 7, then the worker needs to adjust the base frame body 4a, and also prevents the axle from moving to a position where the base frame body 4a cannot move.

[0061] Before the worker operates, the top frame body 4b is in contact with the side wall of the X-direction groove 16 on one side of the X-direction under the action of gravity; at the same time, the base frame body 4a is in contact with the side wall of the Y-direction groove 7 on one end of the Y-direction under the action of gravity, and this position is also the position to which the top frame body 4b will return after the axle is finally received. During the lowering of the axle, the worker observes and predicts the position of the axle, and then pulls the operating part 15 outward, and at the same time rotates the vertical handle 10, at this time the base frame body 4a can be pulled upward by tilting through the operation of the operating cable 12; at the same time, the operating part 15 is swung horizontally, at this time the operating handle 9 is hinged to the receiving frame 3 through the hinge column 19, so that the operating handle 9 and the extension handle 21 can swing, so that the driving column 22 also swings; the driving column 22 is in contact with the inner wall of the driving hole 23, so that the top frame body 4b can also be driven to tilt upward.

[0062] Meanwhile, the X-direction outer side of the bottom frame body 4a is movably attached to the inner wall of the Y-direction groove 7, and the Y-direction outer side of the top frame body 4b is movably attached to the inner wall of the X-direction groove 16, so that the top frame body 4b can only keep its angle and then translate, which can stably support the axle. Meanwhile, the first rolling member 8, the second rolling member, the third rolling member 17 and the fourth rolling member are provided, so that the movement of each structure is more convenient and has smaller resistance and wear, and the subsequent axle and the top frame body 4b can be more smoothly reset, preventing jamming and the like.

[0063] The worker moves the position of the top frame body 4b to a suitable position according to the position and movement state of the axle, successfully supports the axle, and then only needs to loosen the operation part 15. Since the bottom of the Y-direction groove 7 and the bottom of the X-direction groove 16 are inclined, the top frame body 4b is successfully reset to the initial position under the action of the gravity of the axle, and the position is the position that the axle should reach. Therefore, even if the axle shakes or moves during the transfer due to a high moving speed, the axle can finally move to the specified position, which ensures the quality of the axle transfer.

[0064] Furthermore, the connection between the operation cable 12 and the vertical handle 10 is lower than the operation part 15, and the length of the extension handle 21 is smaller than the length of the operation handle 9. According to the principle of a lever, the worker can more easily drive the bottom frame body 4a and the top frame body 4b to move, so that the operation is more convenient. Meanwhile, the worker can simultaneously drive the bottom frame body 4a and the top frame body 4b to move and move the support frame 5 to a suitable supporting position by only operating the operation part 15, which is more convenient and only one worker is needed to easily adjust the position of the top frame body 4b in real time. Meanwhile, when the top frame body 4b and the bottom frame body 4a are relatively moved, the two sides of the vertical handle 10 are continuously attached to the side walls of the vertical groove 14, which can improve the service life of the vertical handle 10.

[0065] It should be further noted that all the "provides" and similar descriptions in the present application (especially the specification) express that there is a connection relationship between two structures, but the specific connection means is not limited too much, and is usually a conventional connection means, that is, it should be understood that the means is prior art and does not need to be described too much. For example, "m is provided with n", only expresses that m structure has n structure, and the specific connection between the two is through welding, riveting, adhesive connection or one-piece forming, which is within the protection scope of the present application; for example, "x is provided with y", only expresses that y and x can relatively rotate, and as to whether the two are connected through a bearing or y directly penetrates x to be connected with x, or other realizable ways, which are within the protection scope of the present application.

[0066] The above description is only the description of the preferred embodiments of the present application, and is not any limitation on the scope of the present application. Any change and modification made by the person skilled in the art according to the above disclosure is within the protection scope of the claims.
