Description

A kind of fork guiding device

technical field

The utility model relates to a cargo fork, in particular to a cargo fork guiding device.

Background technique

At present, traditional pallet forks lack guides or use guide blocks as guide devices. The operation accuracy of the fork is relatively low, and the fork is easy to swing left and right when the fork is extended, the failure rate is high, and there are certain safety hazards at the same time. With the increasing load and stroke of the fork, it is urgent to design a guide device that can make the fork work with high precision and low failure rate.

Utility model content

The purpose of the utility model is to provide a pallet fork guide device, which can improve the working precision of the pallet fork and ensure the safe and reliable operation of the pallet fork. To solve the problems of low operating precision and poor safety and reliability existing in the pallet fork in the prior art.

For this purpose, the utility model adopts the following technical solutions:

A guiding device for a pallet fork, which includes a pallet fork, a guide wheel and a bracket, the pallet fork includes a middle fork and an upper fork, the upper fork is arranged outside the middle fork, wherein the two sides of the middle fork There are several groups of guide wheels correspondingly installed on the top, the guide wheels are rotatably arranged on the bracket through the shaft, the bracket is fixed on both sides of the middle fork by fixing screws, the guide wheels are in contact with the inner wall of the upper fork, When the upper fork stretches out, it is guided by the guide wheel.

In particular, the guide wheel adopts a roller bearing.

In particular, the shaft is passed through the bracket, and both ends of the shaft are axially fixed by pin shafts.

The beneficial effect of the utility model is that, compared with the prior art, several sets of guide wheels are installed on the two sides of the middle fork in the fork guide device. When the upper fork extends outward, the guide wheels guide the upper fork, improving Improve the fork extension accuracy of the fork; at the same time avoid the left and right swing when the upper fork is extended, thereby reducing the failure rate of the fork and improving the safety and reliability of the fork.

Detailed ways

The technical scheme of the utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

Please refer to Fig. 1 and Fig. 2. Fig. 1 is a schematic structural view of a fork guide provided in Embodiment 1 of the present invention; Fig. 2 is a cross-sectional view of A-A in Fig. 1 .

In this embodiment, a fork guiding device includes a fork 1, a roller bearing 2 and a bracket 3, the fork 1 includes a middle fork 4 and an upper fork 5, and the upper fork 5 is arranged between the middle fork 4 In addition, wherein, several groups of roller bearings 2 are correspondingly installed on both sides of the middle fork 4, and the roller bearings 2 are rotatably arranged on the bracket 3 through the shaft 6, and the bracket 3 is fixed in the middle by fixing screws 7. On both sides of the fork 4, the roller bearing 2 is in contact with the inner wall of the upper fork 5, and the upper fork 5 is guided by the roller bearing 2 when the upper fork 5 is stretched out.

The shaft 6 is passed through the bracket 3 , and both ends of the shaft 6 are axially fixed by pin shafts 8 .

The above-mentioned fork guide device improves the precision of the fork extension; at the same time, it avoids the left and right swing when the upper fork is extended, thereby reducing the failure rate of the fork and improving the safety and reliability of the fork.

The above embodiments have only set forth the basic principles and characteristics of the present utility model, and the present utility model is not limited by the above examples. Under the premise of not departing from the spirit and scope of the present utility model, the present utility model also has various changes and changes. These changes All changes and modifications fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
