AI Technical Summary
The existing lifting frame structure is prone to cable sheathing damage, and the hook position is close to the cable, posing a risk of cable damage.
The structure adopts a bell-shaped frame structure made of round steel, with base steel plates and limiting grooves. Cables are tied with cloth tape and fixed at a position far away from the hook lifting point, eliminating the cable pressure plate fixing method. The inner side of the steel plate is ground into rounded corners.
It effectively prevents the cable from being damaged by sharp edges during installation, ensures the stable fixation of the cable to the lifting frame, and avoids cable sheathing damage.

Abstract
Description
Technical Field
[0001] This utility model relates to an improved lifting frame structure. Background Technology
[0002] Existing technology uses a lifting frame on top of the submersible sewage pump for pump lifting and cable fixing. See [link to standard lifting frame structure] for details. Figure 1 2, 3, First steel plate 11, Second steel plate 12, Third steel plate 13, Threaded hole 14, Screw hole 15. See [link to assembly details] for the assembly relationship between the standard lifting frame and surrounding parts. Figure 4 The system includes a power cable clamping plate 21, a power cable 22, a lifting frame 23, a control cable 24, and a control cable clamping plate 25. The first steel plate is bent into shape, with an arc-shaped upper part, a straight middle part, and an inward bend at the bottom. Two symmetrical screw holes are drilled at appropriate positions on the inwardly bent portion for connection to the upper cover of the motor. The second steel plate is welded to the first steel plate at both ends, and eight screw holes are drilled at appropriate positions on the second steel plate for connection to the power cable clamping plate and the control cable clamping plate. The third steel plate is symmetrically arranged, welded to the second steel plate at the top and to the first steel plate at the sides to enhance the rigidity of the first steel plate. (See pump lifting position for details.) Figure 4 The lifting hook is positioned too close to the power and control cables, making it easy for the cables to come into contact and potentially damage their insulation. The sharp edges of the steel plates also pose a risk of cable damage during installation. Therefore, structural design improvements are urgently needed to address these issues. Summary of the Invention
[0003] This utility model addresses the aforementioned problems in the existing technology by providing an improved lifting frame structure to solve the current situation of cable sheath damage caused during hooking or cable installation. This utility model designs an improved lifting frame structure, including a round steel bent frame. The frame is bell-shaped, with an arc-shaped upper bend, a straight middle section, and an inward bend at the bottom. A base steel plate is welded to the bottom of each of the two inward bends, and screw holes are provided on both sides of the base steel plate. A steel plate is welded to the inner side of the middle section of the round steel bent frame, and a limiting groove is provided on the outer side of each steel plate. One limiting groove's opening size matches the diameter of the control cable, and the other limiting groove's opening size matches the diameter of the power cable. The outer surface of the steel plate welded to the inner side of the middle section of the round steel bent frame has rounded corners. The advantage of this utility model is that it uses round steel instead of steel plates, preventing sharp edges from causing cable sheath damage. The cable fixing method using cable clamps has been eliminated. Instead, cables are bundled with cloth tape, and the fixing position is set far away from the hook lifting point to avoid damage to the cables. Cable limiting grooves are installed to facilitate the determination of the relative fixing position of the cables and the new lifting frame. At the same time, the inner side of the steel plate is ground into rounded corners to prevent the cable insulation from being damaged during installation. Attached Figure Description

[0012] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.
[0013] The figure shows an improved lifting frame structure, including a round steel bent frame 1. The frame is bell-shaped, with an upper arc bend, a straight middle section, and a lower inward bend 2. A base steel plate 3 is welded to the bottom of each of the two inward bends. Screw holes 4 are provided on both sides of the base steel plate. A steel plate 5 is welded to the inner side of the middle section of the round steel bent frame. A limiting groove 6 is provided on the outer side of each steel plate. One opening of the limiting groove matches the diameter of the control cable 7, and the opening of the other limiting groove matches the diameter of the power cable 8. The outer surface of the steel plate welded to the inner side of the middle section of the round steel bent frame has rounded corners 9.
[0014] In use, first bolt the base steel plate of the bent round steel frame to the upper part of the submersible sewage pump. Then install the control cable of the submersible sewage pump in the direction of the control cable limit groove, and pass through the limit groove in the opposite direction. Then install the power cable in the direction of the power limit groove, pass through the limit groove in the opposite direction, and lead it out along the bent round steel frame and away from the hook arc segment 10. Use cloth tape to tie the control cable, power cable and surrounding steel parts to complete the fixation. This completes the hoisting.
