Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and more specifically, particularly relates to a crane lifting fork. Background Art

[0002] During the lifting process of the crane, a variety of auxiliary accessories are needed, among which the lifting fork is a common structure that can hold up the pallet of stacked items and directly lift the entire thing.

[0003] Based on the above, the inventors have found the following problems: However, the existing crane fork structures mostly weld the forks directly on both sides of the connecting rod, so that the spacing between the installed forks can be adjusted according to needs, which has poor adaptability, and some structures directly connected by screws have insufficient stability and are not conducive to use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a crane fork is provided to achieve the purpose of having more practical value. Utility Model Content

[0005] The purpose and function of the crane fork of the utility model are achieved by the following specific technical means:

[0006] A crane fork comprises a base frame, wherein both side outer walls of the base frame are penetrated with rectangular grooves, the base frame is equipped with a connecting frame through the rectangular grooves and a snap-fit ​​assembly, and the top of the connecting frame is equipped with ear holes, the surface of the base frame is provided with a sliding groove, a "U"-shaped hole is provided in the sliding groove, and a fork foot is installed in the sliding groove through the "U"-shaped hole and a latch assembly.

[0007] Furthermore, the latch assembly includes a sleeve seat installed on the top of the fork leg, a limiting groove is provided on the inner wall of the sleeve seat, and a latch rod is inserted and installed in the sleeve seat.

[0008] Furthermore, a limit plate is installed on the latch rod, and a spring is mounted on the top of the limit plate located on the latch rod.

[0009] Furthermore, the engaging assembly includes a pair of chambers opened on the side wall of the connecting frame, a rectangular block is slidably installed in the chamber, and a spring 2 is installed in the chamber on one side of the rectangular block.

[0010] Furthermore, the base frame and the connecting frame are both made of metal material, and the surfaces of the base frame and the connecting frame are both provided with a galvanized layer.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. Use the sleeve seat, latch rod, limit plate, spring 1 in conjunction with the "U"-shaped hole. When the spacing between the fork legs needs to be adjusted, pull the latch rod upward to disengage it from the "U"-shaped hole. Then, when the fork legs are slid to the position of the corresponding "U"-shaped hole, release the latch rod. The latch rod is subjected to the reaction force of spring 1, so that the latch rod can be inserted into the "U"-shaped hole again to complete the position adjustment. Through the above operation, the lifting fork can be used for lifting objects of different sizes, greatly improving the overall practicality.

[0013] 2. Through the use of the chamber, rectangular block, spring 2 and rectangular groove, when the overall height of the lifting fork needs to be adjusted, press the rectangular block to make it enter the chamber, and then pull up the connecting frame to a certain position. At this time, the rectangular block is subjected to the reaction force of spring 2, forcing the rectangular block to be engaged in the rectangular groove again, thereby completing the adjustment of the overall height of the lifting fork.

[0023] Example:

[0024] As attached Figure 1 To Attachment Figure 4 As shown:

[0025] The utility model provides a crane fork, comprising a base frame 1, both side outer walls of the base frame 1 are penetrated with rectangular grooves 5, the base frame 1 is installed with a connecting frame 3 through the rectangular grooves 5 and a clamping assembly, and the top of the connecting frame 3 is installed with an ear hole 4, the surface of the base frame 1 is provided with a sliding groove 11, a "U"-shaped hole 6 is provided in the sliding groove 11, and a fork foot 2 is installed on the sliding groove 11 through the "U"-shaped hole 6 and a latch assembly.

[0026] Among them, the latch assembly includes a sleeve seat 10 installed on the top of the fork leg 2, the inner wall of the sleeve seat 10 is provided with a limiting groove, and a latch rod 7 is inserted and installed in the sleeve seat 10, and is used in conjunction with the "U"-shaped hole 6 through the sleeve seat 10, the latch rod 7, the limiting plate 9, and the spring 8. When it is necessary to adjust the spacing between the fork legs 2, the latch rod 7 is pulled up to disengage it from the "U"-shaped hole 6, and then the fork leg 2 is slid to the position of the corresponding "U"-shaped hole 6, and the latch rod 7 is released. The latch rod 7 is subjected to the reaction force of the spring 8, so that the latch rod 7 can be inserted into the "U"-shaped hole 6 again to complete the position adjustment. Through the above operation, the lifting fork can be suitable for lifting objects of different sizes, greatly improving the overall practicality.

[0027] Wherein, a limit plate 9 is installed on the latch rod 7, and a spring 8 is mounted on the top of the limit plate 9 located on the latch rod 7.

[0028] Among them, the locking assembly includes a pair of chambers 12 opened on the side wall of the connecting frame 3, a rectangular block 14 is slidably installed in the chamber 12, and a spring 2 13 is installed on one side of the rectangular block 14 in the chamber 12. The chamber 12, the rectangular block 14, the spring 2 13 are used in conjunction with the rectangular groove 5. When the overall height of the lifting fork needs to be adjusted, the rectangular block 14 is pressed to enter the chamber 12, and then the connecting frame 3 is pulled up to a certain position. At this time, the rectangular block 14 is subjected to the reaction force of the spring 2 13, forcing the rectangular block 14 to be locked into the rectangular groove 5 again, thereby completing the adjustment of the overall height of the lifting fork.

[0029] Among them, the base frame 1 and the connecting frame 3 are both made of metal materials, and the surfaces of the base frame 1 and the connecting frame 3 are provided with a galvanized layer. Through the design of the galvanized layer, the corrosion resistance and oxidation resistance of the base frame 1 and the connecting frame 3 as a whole can be increased, so that the overall service life of this type of lifting fork is increased.

[0030] The specific usage and function of this embodiment are as follows:

[0031] Before using this type of lifting fork, first install the lifting fork on the corresponding forklift, and then determine the spacing between the fork legs 2 according to the size of the object to be lifted. When adjustment is needed, the sleeve seat 10, the latch rod 7, the limit plate 9, the spring 8 are used in conjunction with the "U"-shaped hole 6. When the spacing between the fork legs 2 needs to be adjusted, pull the latch rod 7 upward to disengage it from the "U"-shaped hole 6, and then slide the fork legs 2 to the position of the corresponding "U"-shaped hole 6, release the latch rod 7, and the latch rod 7 is subjected to the reaction force of the spring 8, so that the latch rod 7 can be inserted into the "U"-shaped hole again. The hole 6 completes the position adjustment. Through the above operation, the lifting fork can be suitable for lifting objects of different sizes, which greatly improves the overall practicality. When the overall height needs to be adjusted, the chamber 12, the rectangular block 14, the spring 13 are used in conjunction with the rectangular groove 5. When the overall height of the lifting fork needs to be adjusted, the rectangular block 14 is pressed to make it enter the chamber 12, and then the connecting frame 3 is pulled up to a certain position. At this time, the rectangular block 14 is subjected to the reaction force of the spring 13, forcing the rectangular block 14 to be engaged with the rectangular groove 5 again, thereby completing the adjustment of the overall height of the lifting fork.
