Description

Technical Field

[0001] The utility model relates to a balance device for a double-rail walking mechanism, and more specifically, to a ball hinge assembly balance device for a double-rail walking mechanism. Background Art

[0002] The balance device of a conventional double-rail walking mechanism usually adopts a vertical and horizontal cross-type double-axis arrangement form. The function of the shaft is to transmit the force and torque acting between the wheel and the bogie frame. One shaft rotates along the track direction, and the other shaft rotates perpendicular to the track direction, so as to buffer the impact force transmitted from the uneven track surface to the wheel or the bogie frame, and attenuate the vibration caused thereby, so as to ensure the smooth running of the walking mechanism. The conventional vertical and horizontal cross-type double-axis arrangement form is shown in the appendix Figure 1 , and the balance device includes wheel 1, wheel 2, shaft 3, shaft 4, bearing seat 5, shaft sleeve 6, gland 7, gland 8, end cover 9.

[0003] However, the vertical and horizontal cross-type double-axis arrangement form is relatively complex in manufacturing and installation, and the balance device is directly connected to each group of wheels. Therefore, each group of wheels has to be equipped with a set of this balance device, resulting in a high overall weight and cost of the walking mechanism. Summary of the Utility Model

[0004] Aiming at the defects existing in the prior art, the purpose of the utility model is to provide a ball hinge assembly balance device for a double-rail walking mechanism, which adopts the form of ball hinge assembly to replace the conventional vertical and horizontal cross-type double-axis arrangement form, so as to solve the problems and defects existing in the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A ball hinge assembly balance device for a double-rail walking mechanism, comprising an upper ball hinge seat and a lower ball hinge seat;

[0007] The upper ball hinge seat is arranged at the bottom of the balance beam;

[0008] The lower ball hinge seat is arranged at the top of the bogie frame;

[0009] The contact surface between the upper ball hinge seat and the lower ball hinge seat is set as an inner concave hemispherical seat;

[0010] The contact surface between the lower ball hinge seat and the upper ball hinge seat is set as an outer convex hemispherical seat;

[0011] The hemispherical seat of the upper ball hinge seat is adapted to the hemispherical seat of the lower ball hinge seat.

[0012] Preferably, first connection seats are arranged on both sides of the upper ball hinge seat;

[0013] Both sides of the lower ball joint seat are provided with second connecting seats;

[0014] The first connecting seat and the second connecting seat are connected by bolts.

[0015] Preferably, the upper ball joint seat is arranged at the bottom of the balance beam through bolts.

[0016] Preferably, the lower ball joint seat is arranged at the top of the bogie frame through bolts.

[0017] A ball joint assembly balancing device for a double-rail traveling mechanism provided by the present utility model adopts a ball joint assembly form to replace the conventional vertical and horizontal cross-type double-axis arrangement form, so as to solve the problems and defects existing in the prior art. When the upper ball joint seat and the lower ball joint seat are assembled together, they can roll freely, while the connecting seat can limit the amplitude range. In this way, the ball joint can automatically adjust the impact caused by the unevenness of the two track surfaces, with a simple form and convenient installation. Description of the Drawings

[0019] Figure 2 is a structural support schematic diagram of the ball joint assembly balancing device of the present utility model;

[0020] Figure 3 is Figure 2 the schematic diagram in the B-B direction of Detailed Embodiments

[0021] In order to better understand the above technical solutions of the present utility model, the technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.

[0022] Combined with Figure 2 and Figure 3 shown, a ball joint assembly balancing device for a double-rail traveling mechanism provided by the present utility model includes an upper ball joint seat 10 and a lower ball joint seat 11.

[0023] The upper ball joint seat 10 is fixedly installed at the bottom of the balance beam 100 through bolts.

[0024] The lower ball joint seat 11 is fixedly installed at the top of the bogie frame 200 through bolts.

[0025] The lower surface of the upper ball joint seat 10 (i.e., the contact surface with the lower ball joint seat 11) is set as an inwardly concave hemispherical seat (similar to the shape of a bowl that is concave inward).

[0026] The upper surface of the lower ball joint seat 11 (the contact surface with the upper ball joint seat 10) is set as an outwardly convex hemispherical seat.

[0027] The hemispherical seat on the upper ball joint seat 10 is adapted to the hemispherical seat on the lower ball joint seat 11, so that the upper ball joint seat 10 and the lower ball joint seat 11 can roll freely when assembled together.

[0028] First connection seats 12 are provided on both sides of the upper ball joint seat 10.

[0029] Second connection seats 13 are provided on both sides of the lower ball joint seat 11.

[0030] The first connection seat 10 and the second connection seat 11 are fixedly connected by bolts, which can limit the amplitude range between the upper ball joint seat 10 and the lower ball joint seat 11. In this way, the ball joint formed between the upper ball joint seat 10 and the lower ball joint seat 11 can automatically adjust the impact caused by the unevenness of the two track surfaces. The form is simple and the installation is also convenient.

[0031] When assembling the ball joint assembly balance device of the present utility model during general assembly, directly place the hemispherical seat on the upper ball joint seat 10 onto the hemispherical seat on the lower ball joint seat 11, and lubricating grease should be applied to the contact surface. Bolt connections are used between the first connection seats 10 and the second connection seats 11 on the left and right sides, but an adjustment gap should be left.

[0032] Function of the ball joint assembly: When the traveling mechanism travels on two uneven tracks, the ball joint formed between the upper ball joint seat 10 and the lower ball joint seat 11 can tilt and rotate for leveling, which can buffer the impact along the track direction and also buffer the impact perpendicular to the track direction.

[0033] In summary, the ball joint assembly balance device of the present utility model improves the reliability and stability of the traveling mechanism. Moreover, the form is simpler, the installation method is simplified, it is convenient for replacement, the overall weight of the traveling mechanism is reduced, and the manufacturing, installation and after-sales maintenance costs are reduced.

[0034] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. As long as within the scope of the substantial spirit of the present utility model, changes and modifications to the above-described embodiments will fall within the scope of the claims of the present utility model.
