A hoisting support is welded to the middle of the hoisting beam, and two sets of positioning holes are opened on the surface of the hoisting beam. This application achieves the clamping of the top surface of the glass by placing the glass to be hoisted horizontally between two glass clamping frames, so that the glass comes into contact with the polyurethane elastic layer and the serrated rubber gasket on the inner side of the glass clamping frame, and the clamping plate is moved down by rotating the screw.

Since the telescopic shell assembly is composed of several nested U-shaped shells, and two adjacent U-shaped shells are slidably connected by T-shaped sliders and grooves, as the telescopic shell assembly is stretched, the several U-shaped shells of the telescopic shell assembly extend one by one, so that the fully extended telescopic shell assembly provides a protective barrier for the side of the glass.

Description

Technical Field

[0001] This application relates to the field of glass hoisting technology, and more specifically, to glass handling and hoisting clamps with cushioning and shock absorption. Background Technology

[0002] As is well known, the glass needs to be handled during the production and processing of glass, which requires the use of lifting clamps to hold the glass. For example, the announcement number CN214087333U provides glass sheet lifting clamps that meet the clamping requirements of glass sheets of different sizes and facilitate glass lifting operations.

[0003] However, the glass hoisting clamps mentioned above are not equipped with corresponding buffer and shock absorption structures. During hoisting and transportation, glass products are easily subjected to vibration and impact, which can lead to breakage or cracks. This makes it difficult to ensure the safety of the glass hoisting stage and increases the difficulty of construction.

[0004] To address the aforementioned issues, this application provides a glass handling and hoisting fixture with cushioning and shock absorption. Utility Model Content

[0005] The glass handling and hoisting clamp with cushioning and shock absorption provided in this application adopts the following technical solution:

[0006] A glass handling and hoisting fixture with buffer and shock absorption includes a hoisting beam. A hoisting support is welded to the middle of the hoisting beam, and two sets of positioning holes are opened on the surface of the hoisting beam. Sliding sleeves are fitted at both ends of the hoisting beam, and adjusting columns are welded to the sliding sleeves. A glass clamping frame is welded to the bottom of the adjusting column, and a polyurethane elastic layer is bonded to the inner side of the glass clamping frame. A serrated rubber gasket is fixed to the surface of the polyurethane elastic layer of the glass clamping frame. A screw is threaded onto the upper surface of the glass clamping frame, and a clamping plate is rotatably mounted on the bottom of the screw via a bearing. A silicone pad is pasted on the bottom surface of the clamping plate, and the silicone pad faces the serrated rubber gasket. Telescopic shell assemblies are fixed to the left and right sides of the glass clamping frame by screws.

[0007] The above technical solutions achieve both glass clamping and protection, as well as kinetic energy absorption and buffering, effectively reducing damage to the glass from vibration and impact, and ensuring the safety of glass hoisting.

[0008] Furthermore, the silicone pad surface of the clamping plate is provided with multiple horn grooves, and the top surface of the clamping plate is fixed with multiple valve cores that communicate with the horn grooves.

[0009] The above technical solution enables the negative pressure horn groove to generate an adsorption force on the glass, which helps to maintain the stability of the glass during the hoisting stage.

[0010] Furthermore, the telescopic shell assembly is composed of several nested U-shaped shells, and the size of the several U-shaped shells decreases sequentially along the length of the telescopic shell assembly. The inner side of the U-shaped shell of the telescopic shell assembly is provided with a sliding groove, and the outer side of the U-shaped shell of the telescopic shell assembly is fixed with a T-shaped slider corresponding to the sliding groove.

[0011] The above technical solution enables the fully extended telescopic shell assembly to provide a protective barrier for the glass side, which is beneficial for isolating impacts.

[0012] Furthermore, the upper part of the glass clamping frame is symmetrically provided with two sets of screws and clamping plates, and a circular handwheel is fixedly installed on the top of each screw. The cross-section of the serrated rubber pad on the inner side of the glass clamping frame is a serrated structure.

[0013] The above technical solution facilitates glass clamping and increases cushioning and shock absorption.

[0014] Furthermore, strip-shaped guide ridges are welded to both the upper and lower surfaces of the hoisting beam, and a U-shaped guide groove is provided on the inner side of the sliding sleeve corresponding to the guide ridges.

[0015] The above technical solution satisfies the guiding function of the adjusting column movement and maintains the stability of the connection between the hoisting beam and the sliding sleeve.

[0016] Furthermore, the outer side of the larger U-shaped shell of the telescopic shell assembly is welded with mounting ears, and the surface of the mounting ears is provided with screw holes.

[0017] The above technical solution facilitates the installation of the telescopic shell assembly.

[0018] Furthermore, both sides of the sliding sleeve are threaded with plum blossom knobs, and both plum blossom knobs are inserted into the positioning holes of the suspension rope beam.

[0019] The above technical solutions increase the reliability of the connection between the sliding sleeve and the hoisting beam.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] By placing the glass to be hoisted horizontally between two glass clamping frames, the glass comes into contact with the polyurethane elastic layer and serrated rubber gaskets on the inner side of the glass clamping frames. The top surface of the glass is clamped by rotating the screw to move the clamping plate downward. On this basis, the telescopic shell assemblies on the left and right sides of the glass clamping frames are stretched. Since the telescopic shell assembly is composed of several nested U-shaped shells, and adjacent U-shaped shells are slidably connected by T-shaped sliders and grooves, as the telescopic shell assembly is stretched, the U-shaped shells of the telescopic shell assembly extend one by one. The fully extended telescopic shell assembly provides a protective barrier for the side of the glass. Combined with the polyurethane elastic layer, serrated rubber gaskets, and silicone pads, the glass is clamped while providing protection and absorbing and buffering kinetic energy, effectively reducing the damage to the glass from vibration and impact, and ensuring the safety of glass hoisting.

[0022] By attaching a silicone pad to the bottom of the clamping plate, and installing a valve core in each horn-shaped groove on the silicone pad, and setting the valve core on the top surface of the clamping plate, an external air pump is connected to the valve core. As the air pump draws air from the inside of the horn-shaped groove, the negative pressure of the horn-shaped groove creates an adsorption force on the glass, which helps maintain the stability of the glass during the hoisting stage. It has the advantages of reliable clamping and high safety. Attached Figure Description

[0032] Example

[0033] This application discloses a glass handling and hoisting fixture with cushioning and shock absorption in its embodiments. Please refer to [link to relevant documentation]. Figure 1 and Figure 4The system includes a lifting beam 1, a lifting support 4 welded to the middle of the lifting beam 1, and two sets of positioning holes 5 on the surface of the lifting beam 1. Sliding sleeves 6 are fitted onto both ends of the lifting beam 1, and adjusting columns 2 are welded onto the sliding sleeves 6. A glass clamping frame 3 is welded to the bottom of the adjusting column 2, and a polyurethane elastic layer 15 is bonded to the inner side of the glass clamping frame 3. A serrated rubber gasket 14 is fixed to the surface of the polyurethane elastic layer 15 of the glass clamping frame 3. A screw 8 is threaded onto the upper surface of the glass clamping frame 3, and the bottom of the screw 8 is rotatably mounted via a bearing. The glass clamping frame 3 is equipped with a clamping plate 9, and a silicone pad 17 is attached to the bottom surface of the clamping plate 9. The silicone pad 17 is positioned facing the serrated rubber pad 14. The left and right sides of the glass clamping frame 3 are respectively fixed with telescopic shell assemblies 11 by screws. The glass clamping frame 3 has a U-shaped cross-section, and the polyurethane elastic layer 15 also has a U-shaped structure. The glass clamping frame 3 covers the inner side of the glass clamping frame 3. Two sets of positioning holes 5 are set corresponding to two adjusting posts 2 to meet the requirements of adjusting the distance between the two adjusting posts 2. The serrated rubber pad 14 is designed mainly to increase the friction with the glass and prevent the glass from falling off.

[0034] Please see Figure 1 and Figure 4 The surface of the silicone pad 17 of the clamping plate 9 is provided with multiple horn grooves 18, and multiple valve cores 10 connected to the horn grooves 18 are fixed on the top surface of the clamping plate 9. The valve cores 10 are connected to the external air pump. As the air pump draws out the air inside the horn grooves 18, the negative pressure of the horn grooves 18 generates an adsorption force on the glass, which helps to maintain the stability of the glass during the hoisting stage. The principle of the valve core 10 is a known existing technology and there are mature products. Therefore, its principle will not be explained further. The design principle of the valve core 10 allows it to be used for air extraction under specific conditions.

[0035] Please see Figure 1 and Figure 3 The telescopic shell assembly 11 is composed of several nested U-shaped shells, and the size of the U-shaped shells decreases sequentially along the length of the telescopic shell assembly 11. The inner side of the U-shaped shell of the telescopic shell assembly 11 is provided with a sliding groove 13, and the outer side of the U-shaped shell of the telescopic shell assembly 11 is fixed with a T-shaped slider 12 corresponding to the sliding groove 13. By stretching the telescopic shell assembly 11, the U-shaped shells of the telescopic shell assembly 11 are extended, and the T-shaped slider 12 and the sliding groove 13 are slidably connected to guide and limit the U-shaped shells. This allows the extended telescopic shell assembly 11 to surround the outer side of the glass edge, preventing the glass from directly contacting hard objects and providing good protection.

[0036] Please see Figure 1 and Figure 2Two sets of screws 8 and clamping plates 9 are symmetrically arranged on the upper part of the glass clamping frame 3, and a circular handwheel is fixedly installed on the top of each screw 8. The serrated rubber pad 14 on the inner side of the glass clamping frame 3 has a serrated cross-section. By rotating the screw 8 through the circular handwheel, the screw 8 moves downward and drives the clamping plate 9 closer to the glass, so that the silicone pad 17 of the clamping plate 9 is in direct contact with the glass. Combined with the setting of the serrated rubber pad 14, it satisfies the clamping of the glass and the buffering of impact and vibration.

[0037] Please see Figure 1 and Figure 2 The upper and lower surfaces of the lifting beam 1 are welded with strip-shaped guide ridges. The inner side of the sliding sleeve 6 is provided with a U-shaped guide groove corresponding to the guide ridges. By sliding the sliding sleeve 6, the sliding sleeve 6 is moved laterally along the surface of the lifting beam 1. The strip-shaped guide ridges and guide grooves guide the sliding sleeve 6, increasing the stability of the connection between the sliding sleeve 6 and the lifting beam 1 and ensuring a high degree of fit.

[0038] Please see Figure 1 and Figure 3 The telescopic shell assembly 11 has a mounting ear 16 welded to the outer side of the larger U-shaped shell, and the mounting ear 16 has a screw hole. By passing a screw through the screw hole of the mounting ear 16, the screw is fixedly connected to the glass clamping frame 3, so that the telescopic shell assembly 11 is fixed to the side of the glass clamping frame 3, forming a telescopic protective structure, providing an isolation barrier for the side of the glass, which is conducive to absorbing some of the impact and vibration.

[0039] Please see Figure 1 and Figure 2 Both sides of the sliding sleeve 6 are threaded with plum blossom knobs 7, and both plum blossom knobs 7 are inserted into the positioning holes 5 of the hoisting rope beam. As the plum blossom knobs 7 are rotated, both plum blossom knobs 7 of the sliding sleeve 6 are inserted into the single positioning holes 5 of the hoisting rope beam. This connection structure can maintain the reliability of the connection between the adjusting column 2 and the hoisting beam 1, and also meet the requirements for rapid adjustment of the distance between the two adjusting columns 2.

[0040] The implementation principle of this embodiment is as follows: In use, by moving the adjusting columns 2 at both ends of the lifting beam 1 in opposite directions, the sliding sleeve 6 at the top of the adjusting column 2 is moved laterally along the lifting beam 1. When the gap between the two glass clamping frames 3 meets the required glass size, the plum blossom knob 7 on the surface of the sliding sleeve 6 is rotated to make it insert into the positioning hole 5 on the surface of the lifting beam 1, thereby adjusting the gap between the two glass clamping frames 3. When clamping the glass, by placing the glass to be lifted horizontally between the two glass clamping frames 3, the glass is brought into contact with the polyurethane elastic layer 15 and the serrated rubber pad 14 on the inner side of the glass clamping frame 3. The top surface of the glass is clamped by rotating the screw 8 to drive the clamping plate 9 downward. Based on this, the glass clamping is stretched. The telescopic shell assemblies 11 on the left and right sides of the frame 3 are composed of several nested U-shaped shells. Adjacent U-shaped shells are slidably connected by T-shaped sliders 12 and sliding grooves 13. As the telescopic shell assembly 11 is stretched, the U-shaped shells of the telescopic shell assembly 11 extend one by one, so that the fully extended telescopic shell assembly 11 provides a protective barrier for the side of the glass. At the same time, through the external air pump connected to the valve core 10, as the air pump draws air from the inside of the horn groove 18, the negative pressure of the horn groove 18 generates an adsorption force on the glass, which helps to maintain the stability of the glass during the hoisting stage. Then, the external hoisting equipment acts on the hoisting support 4 of the hoisting beam 1 to move the glass.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
