Description
Technical Field
The invention relates to a trolley driving device, in particular to a trolley slope driving guide device.
Background
The existing trolley is usually driven by a friction driving mechanism, namely, the trolley is moved by friction force generated by contact of friction wheels and the trolley. The rotation plane of the friction wheel should be parallel to the guide rail plane, so that rolling friction is kept between the friction wheel and the trolley, and unnecessary abrasion of the friction wheel in the axial direction is reduced. However, the trolley can go through an up-down slope in addition to the planar running, when the horizontal section is changed into the up-slope stage, the friction wheel rotation plane of the friction driving mechanism arranged on the horizontal section is a horizontal plane, but along with the upward movement of the trolley head, the movement direction of the trolley is gradually changed into an oblique direction from the horizontal direction, and in the process, the contact point of the friction wheel and the trolley can generate movement in the axial direction of the friction wheel, so that the abrasion is increased to the friction wheel. The friction wheel rotation plane of the friction driving mechanism arranged on the slope section is an inclined plane, but in the upward movement process of the trolley head, the inclination angle of the trolley movement track is smaller than the inclination angle of the inclined plane and gradually changes, and similarly, the contact point of the friction wheel and the trolley can move in the axial direction of the friction wheel, so that the abrasion is increased. The same problem occurs during the downhill phase.

Detailed Description
The invention is further illustrated, but is not limited, by the following examples.
As shown in fig. 1, in the prior art, the friction driving mechanism is fixedly connected to the base 100, the rotation shaft of the friction wheel 101 is vertically arranged, when the trolley moves horizontally, the rotation plane of the friction wheel 101 is parallel to the movement direction of the trolley 102, when the trolley 102 moves up and down a slope, the movement direction of the trolley 102 is inclined, and the rotation plane of the friction wheel 101 is still horizontal, so that the movement of the trolley 102 causes the displacement between the trolley 102 and the friction wheel 101 in the vertical direction, thereby causing excessive wear of the friction wheel 101 and reducing the service life.
As shown in fig. 2, the carriage ramp driving guide of the present embodiment includes a base 1, a floating seat 2, a floating guide mechanism 3, and a friction driving wheel mechanism 4. The base 1 and the friction driving wheel mechanism 4 are the same as the prior art, the base 1 is fixedly installed on the ground, the friction driving wheel mechanism 4 comprises a motor 41, a speed reducer 42 and a friction wheel 43, the friction wheel 43 is driven by the motor 41 to drive the speed reducer 42 to rotate, and the friction wheel 43 contacts with the side edge of the trolley body to drive the trolley to move through friction force. In this embodiment, the floating guide mechanism 3 and the friction driving wheel mechanism 4 are fixedly mounted on the floating seat 2, and when the floating seat 2 is in a horizontal state, the rotation axis of the friction wheel 43 of the friction driving wheel mechanism 4 is in a vertical state. The floating mount 2 is made of a metal plate, and a first side of the floating mount 2 is hinged to the base 1 with its hinge shaft 5 disposed parallel to a horizontal plane. The second side (opposite to the first side) of the floating seat 2 is rotated by the hinge shaft 5 to form an attitude inclined to the horizontal plane. A return spring 6 is connected between the bottom of the second side of the floating seat 2 and the base 1, and the return spring 6 can ensure that the floating seat 2 is in a horizontal state without the influence of other external forces, i.e. the friction wheel 43 of the friction driving wheel mechanism 4 rotates in a horizontal direction at this time.
In this embodiment, the friction drive wheel mechanism 4 is fixedly mounted between the first side and the second side of the floating mount 2, and the floating guide mechanism 3 is mounted on the second side of the floating mount 2. The floating guide mechanism 3 is used for driving the second side of the floating seat 2 to move up and down when the inclination angle of the trolley body changes through contact with the trolley body. The specific floating guide mechanism 3 comprises a stand column 31 and two guide wheels 32, wherein the two guide wheels 32 are arranged on the upper portion of the stand column 31 in an up-down mode, the stand column 31 is fixedly connected with the floating seat 2, the circumferential surfaces of the guide wheels 32 are guide surfaces, the distance between the circumferential surfaces of the two guide wheels 32 is larger than the thickness of a trolley body, and the rotating shaft of the guide wheels 32 is parallel to a horizontal plane. During operation of the trolley, the trolley body is located between the upper and lower guide wheels 32.
The traveling direction and the upward and downward slopes of the trolley are determined by the tracks arranged on the ground, when the trolley body travels in the horizontal direction, the trolley body is not contacted with the two guide wheels 32, or the trolley body is contacted with one or both of the two guide wheels 32 but does not generate upward and downward acting force, the floating seat 2 is in a horizontal state under the support of the return spring 6, the rotating plane of the friction wheel 43 of the friction driving wheel mechanism 4 is a horizontal plane, and the friction wheel 43 and the side surface of the trolley body roll friction drive the trolley body to travel.
As shown in fig. 3, when the trolley enters an ascending state, the front end of the trolley body 7 is gradually lifted, and meanwhile, the trolley body 7 contacts with the guide wheel 32 located above and continuously moves upwards, so that the floating guide mechanism 3 drives the floating seat 2 to rotate anticlockwise by taking the hinge shaft 5 as a rotating shaft, and the friction wheel 43 changes the rotating plane along with the rotation of the floating seat 2 to gradually incline corresponding to the inclined state of the trolley body 7. Because the trolley body 7 has larger rotating radius and smaller rotating radius of the floating seat in the ascending process, the rotating plane of the friction wheel 43 cannot be completely consistent with the travelling direction of the trolley in an inclined state, but the relative deviation of the rotating plane and the travelling direction is smaller, compared with the prior art, the axial movement of the friction wheel 43 and the trolley body 7 is greatly reduced, the abrasion is reduced, and the service life is prolonged.
Referring to fig. 4 again, when the trolley enters a downhill state, the front end of the trolley body 7 gradually lowers, and the trolley body 7 contacts the guiding wheel 32 located below and continuously moves downwards so that the floating guiding mechanism 3 drives the floating seat 2 to rotate clockwise by taking the hinge shaft 5 as a rotating shaft, and the friction wheel 43 changes the rotating plane along with the rotation of the floating seat 2 to gradually incline corresponding to the inclined state of the trolley body 7. Similar to the case of ascending, because the trolley body 7 has a larger rotating radius in the descending process and the floating seat 2 has a smaller rotating radius, the rotating plane of the friction wheel 43 cannot be completely consistent with the travelling direction of the trolley in the inclined state, but the relative deviation between the rotating plane and the travelling direction is smaller, and the axial movement of the friction wheel 43 and the trolley body 7 is greatly reduced compared with the prior art, so that the abrasion is reduced, and the service life is prolonged.
The above embodiment is a preferred embodiment of the present invention, and as shown in fig. 5, the present invention may also be used to provide a guide wheel 32 on the upper portion of the upright post 31, a groove 71 formed along the length direction of the trolley body 7 on the side surface of the trolley body 7, and the upper and lower wall surfaces of the groove 71 contact with the guide wheel 32 to drive the floating seat 2 to rotate so as to change the rotation angle of the friction wheel 43, thereby reducing wear.
