[0002] U-shaped lift is a common lifting equipment, mostly used for lifting and transporting equipment, and is widely used in logistics, transportation, manufacturing, and breeding industries.

[0003] The U-shaped lifts commonly seen on the market are mostly similar in structure. They are based on a U-shaped base with a U-shaped or square load-bearing platform on the top. The base and the load-bearing platform are supported by a fork arm, and the fork arm is lifted by an electric cylinder or a hydraulic cylinder. There are some functional deficiencies in actual use and there is room for improvement. For example, whether it is a U-shaped or square load-bearing platform, it has a certain thickness. When installing the lift, a foundation pit for installation needs to be opened in advance on the ground so that the lift can be flush with the ground when retracted, which is convenient for the equipment to be moved up and down. The installation is troublesome and does not have the function of facilitating the movement of equipment without opening a foundation pit.

[0004] Now, a new type of U-shaped pit-free elevator is proposed to solve the above problems. Utility Model Content

[0025] The inner side surface of the first fork arm 3 and the outer side surface of the second fork arm 6 are in contact with each other, and the first fork arm 3 and the second fork arm 6 are movably connected by the connecting shaft 9. The shape and size of the interior of the upper cover 12 are adapted to the shape and size of the exterior of the U-shaped base 1. The bottom end of the concave steel plate 14 is lower than the bottom end of the upper cover 12, and can be used directly without opening a foundation pit.

[0026] Specifically, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the upper cover shell 12 and the concave steel plate 14 constitute the top platform of the elevator. As the upper cover shell 12 sinks and covers the outside of the U-shaped base 1, the bottom of the concave steel plate 14 fits the ground, and the equipment can be driven directly onto the concave steel plate 14. The thickness of the concave steel plate 14 itself is not enough to block the equipment. After the equipment is in place, the electric cylinder 5 retracts and it can be lifted.

[0027] Example 2: An oblique steel plate 15 is provided on the left side of the concave steel plate 14. A plurality of leaf hinges 16 are installed between the concave steel plate 14 and the oblique steel plate 15. There is a distance between the front and rear ends of the oblique steel plate 15 and the upper cover 12. The concave steel plate 14 and the oblique steel plate 15 are movably connected by the hinge 16, with a transition slope and an adjustable angle.

[0028] Specifically, if Figure 5 and Figure 6 As shown, the left oblique steel plate 15 of the concave steel plate 14 can be overlapped on the edge of the high platform, which makes it convenient for the equipment to continue moving along the oblique steel plate 15, and the hinge 16 facilitates the flexible flipping and adjustment of the oblique steel plate 15.

[0029] Example 3: Four sets of lower limiting ridges 17 are provided on the right side of the bottom end of the U-shaped base 1, and two sets of upper limiting grooves 18 are provided on the top end of the upper cover 12. The shape and size of the inner portion of the upper limiting grooves 18 match the shape and size of the outer portion of the upper roller 4. The upper roller 4 can move left and right along the inner portion of the upper limiting grooves 18, thereby preventing the roller from being misaligned.

[0030] Specifically, if Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the lower limiting edge 17 cooperates with the edge of the U-shaped base 1 to limit the walking path of the lower roller 7, and the upper limiting groove 18 can limit the rolling path of the upper roller 4.

[0031] Working principle: When the utility model is in use, first, the U-shaped base 1 serves as the base of the crane. It is directly erected on the ground during installation without the need to dig a foundation pit in advance. The electric cylinder 5 extends, the first fork arm 3 and the second fork arm 6 cross-amplitude increases, the upper cover shell 12 sinks, and the upper cover shell 12 and the concave steel plate 14 form the top platform of the elevator. As the upper cover shell 12 sinks and covers the outside of the U-shaped base 1, the bottom of the concave steel plate 14 fits the ground, and the equipment can be driven directly onto the concave steel plate 14. The thickness of the concave steel plate 14 itself is not enough to block the equipment. After the equipment is in place, the electric cylinder 5 retracts and can be lifted. The equipment enters along the right side of the concave steel plate 14, and the left oblique steel plate 15 of the concave steel plate 14 can be overlapped on the edge of the high platform to facilitate the equipment to continue moving along the oblique steel plate 15. The hinge 16 facilitates the flexible flipping and adjustment of the oblique steel plate 15. When the first fork arm 3 and the second fork arm 6 cross-displace, the upper roller 4 and the lower roller 7 can reduce their friction and play a supporting role at the same time. The lower limit edge 17 cooperates with the edge of the U-shaped base 1 to limit the walking path of the lower roller 7, and the upper limit groove 18 can limit the rolling path of the upper roller 4.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
