Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention aims to provide a turnover mechanism for a spacing-adjustable fork, which can improve the use stability of the spacing-adjustable fork.
Referring to fig. 1-3, fig. 1 is a schematic diagram of a three-dimensional structure of a turning mechanism for a fork with adjustable spacing applied in a fork mechanism according to an embodiment of the present invention; FIG. 2 is a right side view of FIG. 1; fig. 3 is a front view of fig. 1.
The whole fork mechanism is generally connected with a forklift through a vertically arranged mounting plate 1, a mounting seat 2 is convexly arranged at the upper end of the mounting plate 1, a fork supporting rod 6 is penetratingly arranged in the mounting seat 2, the forks 4 are respectively arranged at two ends of the fork supporting rod 6 and can be connected with each other in a relatively horizontal sliding manner, and the sliding can be realized manually or through other mechanical or electronic components, so that the invention is not repeated herein.
To ensure the balance of the load on the fork supporting bar 6, the mounting base 2 is usually located at the center of the fork supporting bar 6. When the left and right forks of the fork 4 are respectively positioned at the outer ends of the fork supporting rods 6, the axial distance of the fork 4 is the largest.
In one embodiment, the tilting mechanism includes a driving mechanism, which may be an oil cylinder 12, or other driving mechanism, which is generally fixedly disposed on the forklift and is disposed at an intermediate position of the fork 4, for providing power to the tilting mechanism.
The turnover mechanism further comprises a pushing component, the pushing component comprises a connecting component and a pushing joint 13, the connecting component is used for connecting the pushing joint 13 with the fork 4 and comprises a inserted rod 17 and a plug bush 10 which are arranged on the back of the fork 4 and connected in a sliding mode, when in a working state, the inserted rod 17 and the plug bush 10 are always in an inserting state, the plug bush 10 is located on the outer side of the inserted rod 17, and the sliding arrangement of the inserted rod 17 and the plug bush 10 is used for adjusting the distance between the fork 4. The outer ends of the pins 17 and the sleeves 10 are typically fixedly attached to the forks 4.
The pushing joint 13 is arranged outside the plug bush 10 and is axially connected with the plug bush in a sliding manner; specifically, a displacement groove 11 may be axially disposed at the outer side of the insert sleeve 10, the section of the displacement groove 11 may be dovetail-shaped, and correspondingly, a sliding block engaged with the displacement groove 11 in a sliding manner is disposed on the pushing joint 13. In this way, the cylinder 12 is always positioned in the center of the fork 4, and the stability of the fork 4 when turning over is ensured.
The pushing joint pushes the fork 4 to turn upwards under the drive of the driving mechanism. Specifically, the plug bush 10 is connected with the oil cylinder 12 through the pushing joint 13, and when the piston rod of the oil cylinder 12 stretches out, the pushing joint 13 pushes the plug bush 10 and further pushes the fork 4 to turn upwards.
Above-mentioned tilting mechanism for adjustable interval fork is because of can promote the fork upwards overturns certain angle for the goods is difficult for droing, has consequently improved the stability in use of adjustable interval fork. Meanwhile, as the pushing joint is connected with the plug bush in an axial sliding way, the pushing joint is always positioned at the middle position of the fork in the process of adjusting the space between the fork, and the left fork and the right fork of the fork are balanced in stress, so that the overturning process is more stable, and the overturning and the space adjustment can be simultaneously carried out.
When the pitch-adjustable turning mechanism for the fork is used, the fork supporting rod 6 can be fixed in the turning process of the fork 4, and can also be synchronously rotated with the fork 4.
Under the condition that the fork supporting rod 6 rotates together with the fork 4 relative to the mounting seat 2, a bearing 8 which is convenient for the rotation of the fork supporting rod 6 can be arranged at the joint between the fork supporting rod 6 and the mounting seat 2, and the round rod 601 is required to be arranged at the joint between the fork supporting rod 6 and the mounting seat 2 in a matched manner, and the round rod 601 is only arranged for the whole non-round rod structure of the fork supporting rod 6. Obviously, when the fork supporting rod 6 is of a round rod structure as a whole, no special arrangement is needed.
In one embodiment, the pushing joint 13 may be further configured to:
For example, the pushing joint 13 includes a first joint 131, a second joint 132, and a third joint 133, and the second joint 132 is slidably disposed along the axial direction of the plug bush 10. Specifically, a sliding block engaged with the yielding groove 11 in a sliding manner is disposed at an end of the second joint 132 connected to the yielding groove 11.
The first joint 131 is disposed at an end of the cylinder 12, that is, an end of the piston rod, and is fixedly connected, and the third joint 133 is disposed between the first joint 131 and the second joint 132 and is longitudinally hinged to both. When the piston rod of the oil cylinder 12 extends, the pushing joints 13 interact, the top moving fork 4 turns upwards, and when the piston rod retracts, the left fork and the right fork of the fork 4 are parallel to the ground.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
The turning mechanism for the spacing-adjustable fork provided by the invention is described in detail above. The principles and embodiments of the present invention have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present invention and its core ideas. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the invention can be made without departing from the principles of the invention and these modifications and adaptations are intended to be within the scope of the invention as defined in the following claims.
