Background

Fork truck is used for carrying the material and with the material stack in the commodity circulation storage trade more, and it comprises aircraft nose, frame and fork structure, and two forks are supported by a crossbeam to the fork structure commonly used, and crossbeam and fork bear the weight of material jointly and rise, descend or rotate, realize the transport and the stack of material. In consideration of the problem that different materials have different widths, two types of fork structures are derived, wherein one type is that the fixed position of the fork on the cross beam can be adjusted, so that the fork can be compatible with materials with various widths for use; the other is that three or four forks are hung on the cross beam, and the forks are sequentially arranged at intervals. Taking four forks as an example, two middle forks are hung on the middle cross beam at the same time, two edge forks are hung on the two edge cross beams respectively, and the middle cross beam and the edge cross beams are supported at the same height. The material with small width only uses two middle forks, and the material with large width simultaneously uses two middle forks and two edge forks. Above two kinds of fork all have because the fork stick up the head or climb the head the mistake that comes and carry the problem, that is to say the atress of each fork is uneven, causes partial fork atress too big, and partial fork atress is little, does not atress even. The reason for this is that the coplanarity of the forks is not guaranteed.

Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Examples

The embodiment of the utility model discloses fork structure for fork truck, it is shown with reference to fig. 1 ~ 2, this fork structure is bilateral symmetry structure, the outside width is up 2000mm, often can exceed automobile body width, it includes straight first crossbeam 2 and second crossbeam 4, and fork 6 and a set of middle fork 8 of two sets of limit portion, above-mentioned first crossbeam 2 and second crossbeam 4 set up along vertical direction interval, and be parallel to each other, first crossbeam 2 is longer, second crossbeam 4 is shorter, both length direction's central line collineation sets up, wholly be geometric symmetry structure. The edge part fork 6 and the middle fork 8 are arranged side by side in parallel and at intervals two by two. The side forks 6 and the intermediate forks 8 have the same structure, have an L-shaped cross section, and include upright arms 18 and lateral fork tips 16, wherein the upper portions of the upright arms 18 of the intermediate forks 8 are fixed to the middle section of the first beam 2, the lower portions of the upright arms 18 are fixed to the second beam 4, the upright arms 18 of the two sets of side forks 6 are fixed to both side sections of the first beam 2, respectively, and the surfaces of the first beam 2 contacting the side forks 6 and the intermediate forks 8 are disposed coplanar with the surfaces of the second beam 4 contacting the intermediate forks 8. Support three at least groups fork by first crossbeam 2 and second crossbeam 4, the material that can compatible multiple width uses, when especially using to wide material, can ensure middle fork 8 and the coplane degree of limit fork 6, solves the fork structure because the fork sticks up the head or climbs the head and come the off-load problem, can not lead to the fact the influence to the load of whole car after installing on the fork truck portal.

Specifically, above-mentioned first crossbeam 2 and second crossbeam 4 are integrated into one piece's whole through-type shaped steel, and shaped steel intensity is big, and bending resistance and torsion resistance are fabulous, and higher plane degree and straightness accuracy can be ensured to the shaped steel that integrated into one piece obtained for both contact fork's surperficial coplane sets up when first crossbeam 2 and second crossbeam 4 are installed along vertical direction interval. On the other hand, the integrally formed section steel has hanging grooves on the surface, and the hanging grooves are used for hanging the edge part fork 6 and the middle fork 8, so that the working time of subsequently processing the hanging grooves is reduced.

In order to improve support intensity, the fork structure still includes auxiliary beam 20, and auxiliary beam 20 is the same with the material of first crossbeam 2, second crossbeam 4, is the shaped steel roof beam, and the upper portion of the arm that stands of limit fork 6 articulates on first crossbeam 2, and the auxiliary beam 20 that the cooperation supported limit fork 6 sets up in first crossbeam 2 below, and the auxiliary beam 20 that the cooperation supported middle fork 6 sets up in the below of second crossbeam 4. When assembled, the surfaces of the auxiliary beams 20 contacting the forks are ensured to be arranged coplanar with the surfaces of the first and second cross beams 2, 4 contacting the forks.
