Detailed Description

the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The core of the invention is to provide the turnover mechanism for the adjustable-spacing pallet fork, which can improve the use stability of the adjustable-spacing pallet fork.

Referring to fig. 1-3, fig. 1 is a three-dimensional structural diagram of a turnover mechanism for a fork with an adjustable spacing applied to 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.

Usually, the whole fork mechanism is 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 penetrates through 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, the sliding can be realized manually or through arranging other mechanical or electronic components, which is not the invention point of the scheme, and therefore, the description is omitted.

to ensure the balanced forces on the fork support bar 6, the mounting seat 2 is usually located at the center of the fork support bar 6. When the left and right forks of the fork 4 are respectively positioned at the outer end portions of the fork support rods 6, the axial distance of the fork 4 is the largest.

In one embodiment, the tilting mechanism comprises a drive mechanism, which may be a cylinder 12 or other drive mechanism, which is usually fixedly arranged on the forklift and is arranged in the middle of the forks 4 for powering the tilting mechanism.

Above-mentioned tilting mechanism still includes the pushing means, the pushing means includes adapting unit and promotion joint 13, adapting unit is used for connecting promotion joint 13 and fork 4, and it is including setting up in inserted bar 17 and the plug bush 10 that the slip of 4 backs of fork meets, and during operating condition, inserted bar 17 and plug bush 10 are in the state of alternating all the time, and plug bush 10 is located the outside of inserted bar 17, and the slip setting of inserted bar 17 and plug bush 10 is for the interval regulation of cooperation fork 4. The outer ends of the insert rods 17 and the inserts 10 are typically fixedly attached to the forks 4.

The pushing joint 13 is arranged outside the plug bush 10 and is in axial sliding connection with the plug bush; specifically, the outside of the insert sleeve 10 may be axially provided with a displacement-yielding groove 11, the section of the displacement-yielding groove 11 may be dovetail-shaped, and correspondingly, the pushing joint 13 is provided with a sliding block which is engaged with the displacement-yielding groove 11 in a sliding fit. In this way, the oil cylinder 12 can be always positioned at the center of the fork 4, and the stability of the fork 4 during overturning is ensured.

the pushing joint is driven by the driving mechanism to push the pallet fork 4 to turn upwards. Specifically, the plug bush 17 is connected with the oil cylinder 12 through the pushing joint 13, and when a piston rod of the oil cylinder 12 extends out, the pushing joint 13 pushes the plug bush 17 to further push the pallet fork 4 to turn upwards.

Above-mentioned adjustable interval tilting mechanism for fork 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, the pushing joint and the plug bush are connected in an axial sliding mode, so that the pushing joint is always located in the middle of the fork in the process of adjusting the distance between the fork and the plug bush, the left fork and the right fork of the fork are stressed in a balanced mode, the overturning process is more stable, and overturning and distance adjustment can be conducted simultaneously.

when the turnover mechanism with the adjustable interval is used, the pallet fork supporting rod 6 can be fixedly arranged and can also be synchronously rotated with the pallet fork 4 in the turnover process of the pallet fork 4.

Under the circumstances that fork bracing piece 6 rotated in the lump for mount pad 2 and fork 4, can set up the bearing 8 that makes things convenient for its pivoted in the junction between fork bracing piece 6 and mount pad 2, matched with, the department of meeting of fork bracing piece 6 and mount pad 2 need set up round bar 601, of course the setting of round bar 601 is only to the whole non-round bar structure of fork bracing piece 6. Obviously, when the fork support rod 6 is a round rod structure as a whole, no special arrangement is needed.

In one embodiment, the push 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 in the axial direction of the socket 17. Specifically, a sliding block which is engaged with the concessional displacement groove 11 and is in sliding fit with one end of the second joint 132, which is connected with the concessional displacement groove 11, is arranged.

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 to the end of the cylinder, and the third joint 133 is disposed between the first joint 131 and the second joint 132, and is longitudinally hinged to both of them. When the piston rod of the oil cylinder 12 extends out, the pushing joint 13 is pushed to interact with each other to jack the fork 4 to turn upwards, and when the piston rod retracts, the left fork and the right fork of the fork 4 are parallel to the ground.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The turnover mechanism for the adjustable-spacing pallet fork provided by the invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
