Description

Technical Field

[0001] The utility model relates to a crossbeam extension structure and belongs to the technical field of textile machinery. Background Art

[0002] The spinning creel is a commonly used production equipment in textile production, which is used to hang and support the yarn reel. Several spindles are hung on the creel crossbeam, and the yarn reel is installed on the spindle. The length of the crossbeam determines the number of spindles to be hung. In the actual production process, it is often necessary to increase the number of spindles on the creel, which requires the two ends of the original creel crossbeam to be appropriately extended and additional spindles to be installed at the extended part. The current method of extending the crossbeam is to install an extension plate at both ends of the crossbeam through bolts, and to drill holes on the extension plate to meet the bolt connection and fixation between the extension plate and the crossbeam, and to install the spindles. This method of extending the crossbeam has the following disadvantages: once the extension plate is drilled, the drilling position can no longer be adjusted, and the extension length of the crossbeam and the installation position of the spindles cannot be adjusted. When it is necessary to adjust the extension length of the crossbeam or change the spacing between the spindles, different extension plates can only be replaced. The disassembly and assembly process is time-consuming and labor-intensive, which seriously affects the production efficiency and cannot meet the actual production needs of the crossbeam extension length and the installation position of the spindles.

[0003] Therefore, there is an urgent need for a beam extension structure with a simple structure and flexible adjustment of the extension length and the installation position of the hanging ingot. Summary of the invention

[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a beam extension structure with simple structure, flexible adjustment of the extension length and the installation position of the hanging ingot, simple disassembly and assembly, and high efficiency.

[0005] The purpose of the utility model is achieved in this way:

[0006] A crossbeam extension structure comprises a crossbeam and an extension beam installed at the end of the crossbeam by fixing bolts. The extension beam is a rectangular square tube structure, and a notch groove is provided on the bottom surface of the rectangular square tube along the longitudinal direction. The head of the fixing bolt is slidably embedded in the notch groove. A plurality of lifting bolts are also slidably embedded in the notch groove for lifting hanging ingots.

[0007] Furthermore, one side or both sides of the top surface of the rectangular square tube of the extension beam are horizontally provided with expansion wings for providing an installation position.

[0008] Furthermore, long waist holes are arranged at intervals on the expansion wings to facilitate the installation of components.

[0009] Furthermore, circular holes are arranged at intervals on the notch groove to facilitate installation and removal of fixing bolts or hanging bolts.

[0010] Furthermore, the fixing bolt is a T-slot bolt.

[0011] Furthermore, the hanging bolt is a T-slot bolt.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a notch groove for sliding of a fixing bolt on the bottom surface of a rectangular square tube, and the head of the fixing bolt is embedded in the groove to install the extension beam on the cross beam, and the extended length can be adjusted arbitrarily; the hanging ingot can be installed on the extension wing or in the notch groove, and the position can also be flexibly adjusted. The overall structure is simple, the cost is low, the disassembly and assembly are simple and efficient, and the utility model can meet the installation requirements of various cross beam extensions.

[0020] See also Figure 1~Figure 4 The utility model relates to a beam extension structure, comprising a beam 1, an extension beam 2 installed at the end of the beam 1 by a fixing bolt 3, the extension beam 2 is a rectangular square tube structure, one side or both sides of the top surface of the rectangular square tube of the extension beam 2 are horizontally provided with an extension wing 6, and long waist holes 7 are arranged at intervals on the extension wing 6, and a hanging ingot or other accessories can be directly installed on the extension wing 6 by a clamp, or the hanging ingot or other accessories can be installed in the long waist hole 7 by a bolt;

[0021] A notch groove 4 is longitudinally provided on the bottom surface of the rectangular square tube, and the head of the fixing bolt 3 is slidably embedded in the notch groove 4. In order to facilitate the fixing bolt 3 to enter and exit the notch groove 4, round holes 8 are arranged at intervals on the notch groove 4. Figure 3 The head of the fixing bolt 3 can be inserted and removed from the circular hole 8. When installing or removing the extension beam 2, the fixing bolt 3 does not need to be inserted and removed from the head and tail of the extension beam 2, thereby improving the installation and removal efficiency of the extension beam 2;

[0022] A plurality of lifting bolts 9 are also slidably embedded in the notch groove 4 for lifting the hanging ingot 5. The installation method of the lifting bolts 9 in the notch groove 4 is the same as that of the fixing bolts 3, and can be inserted and removed from the circular hole 8, thereby improving the installation and removal efficiency of the hanging ingot or other accessories;

[0023] Furthermore, the fixing bolt 3 and the hanging bolt 9 are both selected as T-slot bolts, and the T-shaped head of the T-slot bolt can directly enter and exit from the notch of the notch groove 4. The T-slot bolt can be anchored in the notch groove 4 by rotating it 90 degrees, and no additional round hole 8 is required, which further improves the disassembly and assembly efficiency of the extension beam 2 and the hanging ingot 5 or accessories;

[0024] When the cross beam 1 needs to be extended, the head of the fixing bolt 3 is embedded in the notch groove 4 of the extension beam 2. If it is an ordinary bolt, it is embedded from the head and tail of the notch groove 4. If it is a T-slot bolt, it is embedded in the notch groove 4 nearby and then rotated 90 degrees; insert the fixing bolt 3 into the installation hole on the cross beam 1, use the sliding effect of the fixing bolt 3 in the notch groove 4 to move the extension beam 2 to a suitable length, and then tighten the nut and screw it on the fixing bolt 3 to lock the extension beam 2 on the cross beam 1, and complete the installation of the extension beam 2;

[0025] Similar to the installation method of the fixing bolt 3, the hanging bolt 9 of the hanging ingot 5 is inserted into the notch groove 4 and slid to the required position, and the nut is tightened to complete the extended installation of the hanging ingot 5; in addition, the hanging ingot 5 can also be directly installed on the extended wing 6 of the extension beam 2 by a clamp or bolt;

[0026] When disassembling, the above installation steps can be reversed for quick disassembly; compared with the traditional beam extension method, the beam extension structure of the utility model, the extension of the beam and the extended installation of the hanging ingot accessories are simpler and faster, and the extension length of the beam and the installation position of the hanging ingot can be flexibly adjusted.

[0027] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
