Description

Technical field:

[0001] The present application relates to the technical field of lifting clamps, and in particular to a lifting clamp. Background technology:

[0002] Chinese National Utility Model Patent with application number 202023291487.3 - A new type of steel lifting clamp, including a crane hook fixing ring, the bottom of the front and back sides of the crane hook fixing ring are fixedly connected to connecting plates, the bottom of the outer side of the connecting plate is threadedly connected to a first connecting bolt, the middle of the outer surface of the first connecting bolt is sleeved with an inclined vertical pole clamping plate, the middle of the outer surface of the inclined vertical pole clamping plate is threadedly connected with a second connecting bolt, and the front and rear sides of the outer surface of the second connecting bolt are sleeved with right-angle bayonet clamping plates.

[0003] The patent designs the clamping plates on both sides of the original hoist into different shapes. One side of the clamping plate is a right-angled bayonet, so that the steel is close to the clamp without leaving any gaps during lifting, and the other side is an inclined pole bayonet. During lifting, the steel can be automatically pushed to the right-angle bayonet side due to gravity. However, L-shaped structural members are easy to fall off during lifting, posing a safety hazard of injuring workers. In addition, the clamp needs to tighten the second connecting bolt to fix the right-angle bayonet clamping plate when in use, which is complicated to operate and inefficient. Utility model content:

[0004] In order to solve the above technical problems, the utility model provides a lifting device, which solves the technical problem that when lifting L-shaped components, they are easy to fall off, posing a safety hazard of injuring workers. In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A lifting device, comprising:

[0006] The lifting claw is composed of an inclined section and a vertical section, and the angle between the inclined section and the vertical section is an obtuse angle;

[0007] A connecting rod, one end of which is connected to the lifting claw in a hinged structure, and the other end of the connecting rod is provided with a lifting hook.

[0008] Furthermore, an eye-shaped hanging hole is provided at one end of the inclined section away from the vertical section.

[0009] Further, the angle between the inclined section and the vertical section ranges from 120° to 160°;

[0010] When the vertical section is perpendicular to the connecting rod, the vertical projection of the eye-shaped lifting hole is within the length of the connecting rod.

[0011] Furthermore, a groove is provided on the side of the connecting rod, and through pin holes are provided on the connecting rod and the hanging claw on both sides of the groove, and a pin shaft is provided in the pin hole.

[0012] Furthermore, the pin hole on the hanging claw is located at the connection between the inclined section and the vertical section.

[0013] Furthermore, the hook is in an L-shaped structure and is fixedly connected to the lower end surface of the connecting rod.

[0014] The beneficial effects of the utility model are as follows: a hook is arranged on one side of the connecting rod to limit one side of the L-shaped structural member; the pulling force applied to the inclined section is transmitted to the other side of the member through the vertical section, thereby clamping the member; it has a self-locking function, is easy to operate, and is safe and firm.

[0019] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the utility model will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the utility model. The specific implementation scheme of the utility model is as follows:

[0020] A lifting device comprises a lifting claw 1 consisting of an inclined section 11 and a vertical section 12, a connecting rod 2 is provided on one side of the lifting claw 1 in a hinged structure manner, and a hook 3 is provided on the other end of the connecting rod 2 to limit one side of an L-shaped structural member, and the lifting force applied to the inclined section is transmitted to the other side of the member through the vertical section, thereby clamping the member. The lifting device has a self-locking function, is easy to operate, and is safe and firm.

[0021] It should be noted that an eye-shaped lifting hole 4 is provided at one end of the inclined section 11 away from the vertical section 12 for cooperation with a U-shaped lifting ring for lifting.

[0022] It should be explained that the hook 3 is fixedly connected to the lower end surface of the connecting rod 2 in an L-shaped structure, and the component is clamped in the groove to be fixed in position by utilizing the groove formed between the L-shaped structure and the connecting rod 2.

[0023] Furthermore, the angle between the inclined section (11) and the vertical section (12) ranges from 120° to 160°. In the present embodiment, the angle between the inclined section 11 and the vertical section 12 is 120°. In other embodiments, the angle may be 130°, 140°, 150°, or 160°. It is also ensured that when the vertical section 12 is perpendicular to the connecting rod 2, the vertical projection of the eye-shaped lifting hole 4 is within the length range of the connecting rod 2, thereby preventing the component from flipping over during lifting and improving stability.

[0024] Specifically, a groove 5 is provided on the side of the connecting rod 2 to ensure that the connecting rod 2 can rotate within a certain range. Through pin holes are provided on the connecting rod 2 and the hanging claw 1 on both sides of the groove 5, and a pin shaft 6 is provided in the pin hole.

[0025] The pin hole on the lifting claw 1 is located at the connection between the inclined section 11 and the vertical section 12. For an L-shaped member, the vertical section 12 can be used to limit its side, and the hook 3 can be used to fix the other opposite side, with a high degree of fit.

[0026] The working principle and working process of the utility model are as follows:

[0027] First, connect the U-shaped lifting ring with the eye-shaped lifting hole 4, and then use the slot of the hook 3 to clamp it on one side of the L-shaped component, place the vertical section on the other side of the component, and use the chain to pull the inclined section 11 upward through the U-shaped lifting ring. The inclined section 11 and the vertical section 12 rotate around the pin 6, and then the inner side of the vertical section 12 fits against the side of the L-shaped component, and cooperates with the hook 3 to automatically clamp the L-shaped component to ensure the stability of the lifting.
