Description

Technical Field

[0001] The utility model relates to the technical field of hoisting clamps, in particular to a hoisting clamp. Background Art

[0002] A lifting fixture is a device used to grasp, secure, or lift objects. It typically consists of a fixture body, a fixture mechanism, a rotating device, and a hook. Depending on the fixture's principle and application scenario, there are many types of lifting fixtures. Lifting fixtures play a vital role in modern industrial production, logistics, transportation, and construction. For example, ALC panels used in construction are often hoisted during transportation.

[0003] When existing lifting clamps are in use, anti-slip pads are generally installed on the clamp heads. Since the anti-slip pads are mostly made of rubber, the clamps will be exposed to the air for a long time when not in use, which can easily cause the anti-slip pads to oxidize, reduce the clamping stability and affect the service life. Therefore, we propose a lifting clamp to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a lifting clamp.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A lifting clamp comprises a lifting clamp main body, the bottom end of the lifting clamp main body is fixedly connected to a mounting frame, and a plug-in block is inserted into the interior of the mounting frame, an anti-slip mechanism is glued to the outer side of the plug-in block, a limiting mechanism is inserted into the interior of the plug-in block, a protective mechanism is installed below the mounting frame, and a magnetic barrier strip is fixedly connected to the side of the mounting frame.

[0007] Preferably, the anti-slip mechanism includes an anti-slip rubber pad, the surface of the plug-in block is glued with an anti-slip rubber pad, and the surface of the anti-slip rubber pad is provided with multiple groups of anti-slip rubber strips at equal distances, and the surfaces of the multiple groups of anti-slip rubber strips are all provided with anti-slip grooves. The anti-slip grooves provided on the surfaces of the multiple groups of anti-slip rubber strips can increase the friction between the surface of the anti-slip rubber strip and the material.

[0008] Preferably, the limiting mechanism includes a reset spring, and grooves are provided in the upper and lower interiors of the plug-in block, and the inner wall of the groove is welded to one end of the reset spring, and the other end of the reset spring is welded to the surface of the telescopic block. The grooves provided inside the plug-in block can conveniently accommodate the function of the telescopic block.

[0009] Preferably, the telescopic card block is inserted into the groove and fixedly connected to the limiting sliders on both sides of one end. The inner wall of the groove is provided with a sliding groove adapted to the limiting slider, and the limiting slider can play the role of limiting and guiding the movement of the telescopic card block.

[0010] Preferably, the cross section of the telescopic card block is set to be rectangular, and the upper and lower sides of the installation frame are provided with through holes adapted to the telescopic card block. By inserting the telescopic card block into the through holes, the plug-in block can be easily installed in the installation frame.

[0011] Preferably, the protective mechanism includes a mounting block, the lower surface of the mounting frame is fixedly connected to the mounting block, and a hinge block is hinged inside the mounting block, and the outer end of the hinge block is fixedly connected to a protective cover frame. The protective cover frame is engaged with the surface of the anti-slip rubber pad, which can reduce the oxidation of the surface of the anti-slip rubber pad.

[0012] Preferably, the cross section of the magnetic barrier strip is set to be U-shaped, and the end face size of the protective cover frame is the same as the surface size of the magnetic barrier strip, so that the magnetic barrier strip can facilitate the function of limiting the protective cover frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By toggling the protective cover frame, the device can facilitate the rotation of the hinge block inside the mounting block, thereby controlling the protective cover frame to engage or stay away from the surface of the anti-slip mechanism. The magnetic force of the magnetic barrier strip itself can facilitate the adsorption of the protective cover frame, thereby increasing the stability of the protective cover frame when engaged, and facilitating the lifting fixture body to cover and protect the anti-slip mechanism as a whole when not in use, thereby reducing oxidation of the anti-slip mechanism and increasing the service life of the anti-slip mechanism.

[0015] 2. By lifting the main body of the lifting fixture, the device can enable the two sets of installation frames to clamp both sides of the material, thereby increasing the clamping stability through the friction of the anti-slip rubber pad and the anti-slip rubber strip surface. At the same time, the telescopic clamping block can be telescopically moved inside the plug-in block, which can effectively facilitate the disassembly and installation between the installation frame and the plug-in block, and the anti-slip rubber pad can be quickly replaced after wear during use.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-4 A lifting clamp comprises a lifting clamp main body 1, the bottom end of the lifting clamp main body 1 is fixedly connected to a mounting frame 2, and a plug-in block 3 is inserted into the interior of the mounting frame 2. The mounting frame 2 and the plug-in block 3 are plug-in installed, so the anti-slip mechanism 4 as a whole can be quickly replaced. The outer side of the plug-in block 3 is glued with an anti-slip mechanism 4, and the interior of the plug-in block 3 is inserted with a limiting mechanism 5. A protective mechanism 6 is installed under the mounting frame 2, and a magnetic barrier strip 7 is fixedly connected to the side of the mounting frame 2.

[0027] Further, refer to Figure 2 and Figure 3 It can be seen that the anti-slip mechanism 4 includes an anti-slip rubber pad 41, the surface of the plug-in block 3 is glued with the anti-slip rubber pad 41, and the surface of the anti-slip rubber pad 41 is evenly spaced with multiple groups of anti-slip rubber strips 42, and the surfaces of the multiple groups of anti-slip rubber strips 42 are all provided with anti-slip grooves. The multiple groups of anti-slip rubber strips 42 arranged on the surface of the anti-slip rubber pad 41 can effectively increase the surface friction of the anti-slip rubber pad 41 and improve the clamping stability of the anti-slip rubber pad 41.

[0028] Further, refer to Figure 3 and Figure 4 It can be seen that the limiting mechanism 5 includes a reset spring 51, and grooves are provided on the upper and lower interiors of the plug-in block 3. The inner wall of the groove is welded to one end of the reset spring 51, and the other end of the reset spring 51 is welded to the surface of the telescopic block 52. The elastic force of the reset spring 51 itself can facilitate the pushing of the telescopic block 52.

[0029] Further, refer to Figure 3 and Figure 4It can be seen that the telescopic card block 52 is inserted into the groove and fixedly connected to the limiting slider 53 on both sides of one end. The inner wall of the groove is provided with a sliding groove adapted to the limiting slider 53. By moving the telescopic card block 52 in the groove, the limiting slider 53 can slide in the sliding groove, thereby playing the role of limiting and guiding the telescopic card block 52.

[0030] Further, refer to Figure 3 and Figure 4 It can be seen that the cross-section of the telescopic card block 52 is set to be rectangular, and through holes that are compatible with the telescopic card block 52 are opened on the upper and lower sides of the installation frame 2. Through the through holes opened on the upper and lower sides of the installation frame 2, the telescopic card block 52 can be inserted into the through holes, which facilitates the function of limiting the installation frame 2 and the plug-in block 3.

[0031] Further, refer to Figure 1 and Figure 2 It can be seen that the protective mechanism 6 includes a mounting block 61, the lower surface of the mounting frame 2 is fixedly connected to the mounting block 61, and a hinge block 62 is hinged inside the mounting block 61, and the outer end of the hinge block 62 is fixedly connected to the protective cover frame 63. The hinge block 62 can be easily installed through the mounting block 61, and the movement of the protective cover frame 63 can be controlled by rotating the hinge block 62 inside the mounting block 61.

[0032] Further, refer to Figure 1 and Figure 2 It can be seen that the cross section of the magnetic baffle 7 is set to be U-shaped, and the end face size of the protective cover frame 63 is the same as the surface size of the magnetic baffle 7. By setting the cross section of the magnetic baffle 7 to be U-shaped, the function of limiting the protective cover frame 63 can be facilitated.

[0033] Working principle: When the utility model is in use, when the lifting fixture body 1 is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4By pulling the protective cover frame 63, the protective cover frame 63 can drive the hinge block 62 to rotate inside the mounting block 61. When the protective cover frame 63 is away from the magnetic barrier 7, the anti-skid rubber pad 41 and the anti-skid rubber strip 42 can be leaked as a whole. At this time, the lifting fixture body 1 can be engaged with the surface of the material. By lifting the lifting fixture body 1, the lifting fixture body 1 can drive the mounting frame 2 and the plug-in block 3 to move, so that the anti-skid rubber pad 41 and the anti-skid rubber strip 42 are squeezed with the surface of the material, which is convenient for lifting the material. When the anti-skid rubber pad 41 and the anti-skid rubber strip 42 are squeezed with the surface of the material, the material can be lifted. When the rubber strip 42 needs to be replaced, the retractable card block 52 can be installed by using a tool, so that the retractable card block 52 can be retracted into the plug-in block 3 and the return spring 51 is compressed, so that the plug-in block 3 can be pulled out from the inside of the installation frame 2. After the anti-slip rubber pad 41 is replaced, the plug-in block 3 drives the retractable card block 52 to be inserted into the installation frame 2. When the inner wall of the installation frame 2 conflicts with the surface of the plug-in block 3, the elastic force of the return spring 51 itself can make the retractable card block 52 return to the inside of the installation frame 2, and the plug-in block 3 is locked and installed in the installation frame 2.

[0034] The above is the entire working principle of the utility model.

[0035] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology.
