AI Technical Summary
Due to the lack of a locking structure of the existing rod spreader, the rod spreader is prone to slide or fall along the axis during the lifting process, which poses a major safety hazard.
A rod spreader is designed, adopting a "C"-shaped structure of hooks and connecting plates. Through the through holes of the connecting plate and the movement of the connecting rod, a barrier structure to the rod is formed to prevent the rod from sliding.
It effectively prevents the rod member from moving along the axis on the spreader, improves the safety of lifting, and is suitable for rod members with circular and rectangular cross-sections.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rod hangers, in particular to a rod hanger. Background Art
[0002] In the heat treatment production process, it is often necessary to hoist and transfer various rods used for heat treatment. The cross-section of the rods has a circular structure or a rectangular structure. The commonly used hoist is a "J"-shaped hook, which is used to hoist and transfer the rods by setting multiple hooks on a horizontally set hanging rod. However, due to the lack of a locking structure, this type of hook makes it easy for the rod to slide axially relative to the hook under the action of inertia when it moves or stops along the axis, or even fall, which poses a great safety hazard. Utility Model Content
[0003] In order to solve the deficiencies in the prior art, the utility model provides a rod hanger, which can effectively prevent the rod from sliding and has higher hoisting safety.
[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:
[0005] A rod hanger comprises a hook and a connecting plate.
[0006] The cross section of the hook is a "C" shaped structure, the lower horizontal section and the vertical section of the hook are used to abut the rod, and the front end of the upper horizontal section of the hook is provided with a connecting rod, and its length direction is consistent with the extension direction of the cross section of the hook;
[0007] A hanging part is provided on the top of the connecting plate for connecting the cable of the lifting equipment. The connecting plate is provided with a through hole, which includes a first strip hole and a second strip hole spaced apart from each other. The upper ends of the first strip hole and the second strip hole are connected to each other. The lower end of the first strip hole is located in the middle section of the connecting plate, and the lower end of the second strip hole is located at the lower end of the connecting plate. The hanging part is located above the second strip hole.
[0008] The connecting plate is sleeved on the connecting rod through the through hole, and the distance between the first strip hole and the vertical section of the hook is greater than the distance between the second strip hole and the vertical section of the hook; the distance between the lower end of the first strip hole and the bottom of the connecting plate is greater than half of the height of the hook side plate, and less than the distance between the lower horizontal section and the upper horizontal section of the hook.
[0009] The beneficial effects of the utility model are as follows: the solution can prevent the rod from moving along the axis on the hanger and prevent the rod from falling; and the hanger of this structure can adapt to rods with circular and rectangular cross-sections at the same time.

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0017] like Figures 1 to 4 As shown, a rod hanger includes: a hook 1 and a connecting plate 3.
[0018] The cross section of the hook 1 is a "C" shaped structure. The lower horizontal section and the vertical section of the hook 1 are used to abut the rod. The front end of the upper horizontal section of the hook 1 is provided with a connecting rod 2, and its length direction is consistent with the extension direction of the cross section of the hook 1.
[0019] A hanging portion 31 is provided on the top of the connecting plate 3 for connecting the cable of the lifting equipment. The connecting plate 3 is provided with a through hole, which includes a first strip hole 32 and a second strip hole 33 spaced apart from each other. The upper ends of the first strip hole 32 and the second strip hole 33 are connected to each other, the lower end of the first strip hole 32 is located in the middle section of the connecting plate 3, the lower end of the second strip hole 33 is located at the lower end of the connecting plate 3, and the hanging portion 31 is located above the second strip hole 33.
[0020] The connecting plate 3 is sleeved on the connecting rod 2 through the through hole, so that the connecting rod 2 can move in the first strip hole 32 and the second strip hole 33, and the distance between the first strip hole 32 and the vertical section of the hook 1 is greater than the distance between the second strip hole 33 and the vertical section of the hook 1; the distance between the lower end of the first strip hole 32 and the bottom of the connecting plate 3 is greater than half of the height of the side plate of the hook 1, and less than the distance between the lower horizontal section and the upper horizontal section of the hook 1, so when the connecting rod 2 is located at the lower end of the first strip hole 32, the lower end of the connecting plate 3 can also be located above the lower horizontal section of the hook 1 to avoid the connecting plate 3 from abutting against the edge of the lower horizontal section of the hook 1.
[0021] The above structure allows the hook 1 to have two usage states at the same time: first, Figure 1 As shown, the connecting rod 2 is hung by the lower end of the second strip hole 33. At this time, the lower end of the connecting plate 3 and the lower horizontal section of the hook 1 have the maximum distance, so that the opening of the hook 1 is completely exposed. At this time, the hook 1 can be used as an ordinary hook. Figures 2 to 4 As shown, when hoisting the rod, first use the lower horizontal section and vertical section of the hook 1 to abut against the outer wall of the rod, then move the connecting plate 3 downward along the second strip hole 33 to move the connecting rod 2 into the first strip hole 32, and then move the connecting plate 3 upward to hang the connecting rod 2 at the lower end of the first strip hole 32. At this time, the lower end of the connecting plate 3 is at the opening of the hook 1, forming a blocking structure for the rod. Because the hanging portion 31 is located above the second strip hole 33, and there is a gap between the first strip hole 32 and the second strip hole 33, the first strip hole 32 and the hanging portion 31 are respectively located on both sides of the connecting plate 3, and the two are not arranged along the same trajectory along the length direction of the connecting plate 3. Therefore, when the lifting equipment applies an upward pulling force to the connecting plate 3 through the hanging portion 31, the lower end of the connecting plate 3 will swing around the connecting rod 2 toward the inside of the hook 1 until the lower end of the connecting plate 3 abuts against the side wall of the rod, thereby using the connecting plate 3 to press the rod into the hook 1, and the greater the weight of the rod, the greater the pressure generated by the connecting plate 3 on the rod; thereby preventing the rod from moving along the axis on the sling and preventing the rod from falling; and a sling of this structure can simultaneously adapt to rods with circular and rectangular cross-sections.
[0022] Preferably, the lower transverse section, the upper transverse section and the vertical section of the hook 1 are all plate-like structures to increase the contact surface with the rod and improve the clamping stability of the rod.
[0023] Preferably, the hanging portion 31 is a shaft structure or a hole structure.
[0024] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
