Description

Technical Field

[0001] The utility model relates to the technical field of forklift fork racks, and more specifically, the utility model relates to a widened forklift fork rack. Background Art

[0002] It is known that a forklift realizes the function of shoveling goods through the forks installed on the fork rack. Thus, it can be seen that the forks and the fork rack are basic components configured on the forklift; among them, ordinary forklifts are generally equipped with 2 forks, which are symmetrically installed on the forklift fork rack. In some application scenarios, it is necessary to widen the fork rack and configure 4 forks, so as to be able to fork two stacks of independent goods at the same time.

[0003] However, in actual use, as Figure 3 shown, the existing forklift is configured with a widened fork rack with 4 forks, but it does not consider how to solve the problems of unstable and deviated center of gravity of the goods. Therefore, after long-term use, the deformation of the outermost side of the fork rack is larger than that of the inner side, resulting in the problem that the two stacks of goods deviate towards the outside of the forklift respectively; if the height of the goods is relatively high, the outside deviation problem will cause the center of gravity of the goods to be unstable, and thus it is easy to occur a safety accident of the goods tipping over during the process of the driver shoveling and transporting the goods; therefore, a widened forklift fork rack is proposed as a further improvement. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a widened forklift fork rack to solve the problems raised in the above background art.

[0005] To achieve the above object, the utility model provides the following technical solution: a widened forklift fork rack, the forklift fork rack includes: an upper cross beam, a lower cross beam, two inner forks and two outer forks,

[0006] Both sides of the upper cross beam are respectively fixedly connected to both sides of the lower cross beam through side plates. The vertical sections of the two inner forks and the vertical sections of the two outer forks are detachably installed on the upper cross beam, and the vertical sections of the two inner forks and the vertical sections of the two outer forks are both clamped to the lower cross beam;

[0007] The two inner forks are located between the two outer forks, and the height of the upper surface of the horizontal section of the inner fork is lower than the height of the upper surface of the horizontal section of the outer fork.

[0008] Further, the distance between the upper surface of the horizontal section of the inner fork and the upper surface of the horizontal section of the outer fork is set as D, and the range of D is set as 20 - 30 mm.

[0009] Further, the width of the inner fork is set as W1, and the width of the outer fork is set as W2, then W1 < W2.

[0012] Further, a marking groove is provided in the middle of the bottom of the lower cross beam, and the marking groove is located between the two inner forks.

[0013] Technical effects and advantages of the present utility model:

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further elaborates on the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] As shown in the attached Figure 1 and attached Figure 2 A widened forklift fork frame as shown, the forklift fork frame includes: an upper cross beam 1, a lower cross beam 2, two inner forks 3 and two outer forks 4,

[0021] Both sides of the upper cross beam 1 are respectively fixedly connected to both sides of the lower cross beam 2 through side plates 5. The vertical sections of the two inner forks 3 and the vertical sections of the two outer forks 4 are detachably installed on the upper cross beam 1, and the vertical sections of the two inner forks 3 and the vertical sections of the two outer forks 4 are both clamped to the lower cross beam 2;

[0022] Two inner forks 3 are located between two outer forks 4, and the height of the upper surface of the horizontal section of the inner fork 3 is lower than the height of the upper surface of the horizontal section of the outer fork 4.

[0023] Among them, the conventional widened fork rack is realized by lengthening the upper cross beam 1 and the lower cross beam 2 of the ordinary forklift fork rack. Generally, an ordinary forklift is equipped with 2 forks. Therefore, the utility model simultaneously transports two stacks of goods through two inner forks 3 and two outer forks 4.

[0024] Among them, the inner fork 3 and the outer fork 4 have the same shape as the conventional fork, both are L-shaped, and both the inner fork 3 and the outer fork 4 are divided into a vertical section and a horizontal section;

[0025] Among them, by setting the height of the upper surface of the horizontal section of the inner fork 3 to be lower than the height of the upper surface of the horizontal section of the outer fork 4, when the inner fork 3 and the outer fork 4 shovel the goods, the two goods will tilt towards each other, and then the two stacks of goods will tilt towards the inside and lean against each other, forming a relatively stable structure, solving the problem that the center of gravity of the goods is unstable and tilting outwards;

[0026] In a preferred embodiment, as shown in the attached Figure 1 and the attached Figure 2 figure, the distance between the upper surface of the horizontal section of the inner fork 3 and the upper surface of the horizontal section of the outer fork 4 is set to D, and the range of D is set to 20 - 30 mm; in order to utilize the distance difference between the upper surface of the horizontal section of the inner fork 3 and the upper surface of the horizontal section of the outer fork 4 to ensure that the two stacks of goods tilt towards the inside and lean against each other after tilting; and the deformation amount of the inner fork 3 under force is within a controllable range.

[0027] In a preferred embodiment, as shown in the attached Figure 1 and the attached Figure 2 figure, the width of the inner fork 3 is set to W1, and the width of the outer fork 4 is set to W2, then W1 < W2;

[0028] Among them, if the width of the inner fork 3 is less than the width of the outer fork 4 and the other dimensions of the two are the same, then the strength of the inner fork 3 is less than the strength of the outer fork 4. Therefore, when shoveling the goods, the deformation amount of the inner fork 3 will be greater than that of the outer fork 4, and then it is ensured that after the inner fork 3 deforms under force, the two goods will tilt towards each other and lean against each other.

[0029] In a preferred embodiment, as shown in the attached Figure 1 and the attached Figure 2 figure, the difference range between W1 and W2 is set to be 20 - 30 mm; so that the strength of the inner fork 3 is less than the strength of the outer fork 4, and when shoveling the goods, the deformation amount of the inner fork 3 is greater than that of the outer fork 4.

[0030] In a preferred embodiment, as shown in the attached Figure 1and the attached Figure 2 As shown, the thickness of the horizontal section of the inner fork 3 is less than that of the horizontal section of the outer fork 4, so that the strength of the inner fork 3 is less than that of the outer fork 4. When shoveling goods, the deformation amount of the inner fork 3 is greater than that of the outer fork 4.

[0031] In a preferred embodiment, as shown in the attached Figure 1 and the attached Figure 2 As shown, a marking groove 6 is provided in the middle of the bottom of the lower crossbeam 2, and the marking groove 6 is located between the two inner forks 3; so as to ensure that the two inner forks 3 and the two outer forks 4 can carry two stacks of goods at the same time.

[0032] Principle of use: By setting the height of the upper surface of the horizontal section of the inner fork 3 to be lower than that of the upper surface of the horizontal section of the outer fork 4, when the inner fork 3 and the outer fork 4 shovel goods, the two goods will tilt towards each other, and then the two stacks of goods will tilt towards the inside and lean against each other, forming a relatively stable structure, solving the problem that the center of gravity of the goods is unstable and tilts outwards;

[0033] By setting the width of the inner fork 3 to be smaller than that of the outer fork 4, and the other dimensions of the two are the same, the strength of the inner fork 3 is less than that of the outer fork 4. Therefore, when shoveling goods, the deformation amount of the inner fork 3 will be greater than that of the outer fork 4, and then it is ensured that after the inner fork 3 deforms under force, the two goods will tilt towards each other and lean against each other.
