Description

Technical Field

[0001] This utility model relates to the technical field of steel-plastic grating production equipment, specifically a positioning device for steel-plastic grating production. Background Technology

[0002] Steel-plastic geogrid, as an important geosynthetic material, is widely used in the reinforcement of highways, railways, water conservancy and other engineering projects. It typically consists of transverse and longitudinal steel-plastic geogrid strips interwoven through welding to form a mesh structure. During production, the steel-plastic geogrid strips need to be pre-wound onto I-beam geogrid winding rollers and positioned and laid out near the welding equipment. Traditionally, the winding rollers for I-beam geogrid are fixed using simple brackets or fixed shafts. For example, a cutting device for steel-plastic geogrid production, disclosed in CN214349326U, includes a device platform and a feeding roller located at one end of the top surface of the platform. This feeding roller lacks the function of preventing the geogrid strips from loosening, easily leading to loosening of the strips during the laying-out process, affecting the winding order of the geogrid strips. If it becomes entangled with other equipment or components, it will affect the subsequent production of the steel-plastic geogrid.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0013] Beneficial effects

[0014] This utility model provides a positioning device for steel-plastic grating production. Compared with the prior art, it has the following advantages: the winding roller of the I-beam grating strip with steel-plastic grating strips is movably mounted on the semi-threaded column, and then the anti-detachment component is mounted on the semi-threaded column to prevent the winding roller of the I-beam grating strip from detaching from the semi-threaded column, thus limiting the position of the steel-plastic grating strip. Then, the sleeve is pulled to move the moving column in the slot until the sleeve is detached from the top of the column. Under the action of spring contraction force, the pressure roller presses the outer ring of the steel-plastic grating strip on the winding roller of the I-beam grating strip, preventing the steel-plastic grating strip from loosening on the winding roller, ensuring the orderly laying of the steel-plastic grating strip, avoiding entanglement with other equipment or components due to loosening, and ensuring the normal subsequent production of steel-plastic grating.

Detailed Implementation

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example: Please refer to Figure 1-3 A positioning device for steel-plastic grating production includes an I-beam grating bar winding roller 1, on which a positioning structure is provided;

[0021] It should be noted that steel-plastic grid strips are wound on the I-beam grid bar winding roller 1. The steel-plastic grid mesh is formed by welding multiple horizontal steel-plastic grid strips and multiple vertical steel-plastic grid strips together. The positioning structure is used to install the I-beam grid bar winding roller 1. In actual work, the positioning structure can be fixedly set near the welding equipment of the steel-plastic grid mesh. Its specific installation position is set according to the specific layout of the welding workshop and is not limited here.

[0022] Specifically, the positioning structure includes a circular groove seat 2, a semi-threaded column 3 installed at the center of the inner bottom surface of the circular groove seat 2, a turntable 4 movably mounted on the semi-threaded column 3, an I-beam grid bar winding roller 1 movably mounted on the semi-threaded column 3 and movably attached to the turntable 4, multiple pressing components are installed in a circular array on the outer wall of the circular groove seat 2, and an anti-detachment component is movably mounted on the semi-threaded column 3 through threads;

[0023] Specifically, each pressing component includes a groove 5, a slider 6 is movably mounted on the groove 5, a support rod 7 is mounted on the slider 6, a C-shaped frame 8 is mounted on one end of the support rod 7, a pressure roller 9 is movably inserted into the C-shaped frame 8, and a spring 10 is installed between the slider 6 and the groove 5; specifically, a column 14 is mounted on one end of the groove 5, a slot 15 is opened on the upper wall of the slider 6, a movable column 16 is movably inserted into the slot 15, a sleeve 17 is mounted on one end of the movable column 16, and the sleeve 17 matches the column 14;

[0024] It should be noted that before installing the H-beam grid bar winding roller 1, the sleeve 17 is movably mounted on the column 14. At this time, the spring 10 is in a stretched state, the slider 6 is located at the end of the groove 5 away from the circular groove seat 2, and the pressure roller 9 is away from the semi-threaded column 3. The H-beam grid bar winding roller 1, which is wound with steel-plastic grid bars, is movably mounted on the semi-threaded column 3. Then, the anti-detachment component is movably mounted on the semi-threaded column 3 via a threaded connection to prevent the H-beam grid bar winding roller 1 from detaching from the semi-threaded column 3, thus achieving the positioning of the steel-plastic grid bar. The sleeve 17 is then pulled to move the movable column 16 in the slot 15 until the sleeve 17 disengages from the top of the column 14. Under the contraction force of the spring 10, the slider 6 moves in the groove 5 until the pressure roller 9 presses against the outer ring of the steel-plastic grid strip on the I-beam grid strip winding roller 1. This prevents the steel-plastic grid strip from becoming loose on the I-beam grid strip winding roller 1, ensuring the orderly laying of the steel-plastic grid strip and avoiding entanglement with other equipment or components due to loosening, thus ensuring the normal subsequent production of the steel-plastic grid.

[0025] Specifically, the anti-detachment component includes a nut 11, which is movably fitted onto a semi-threaded post 3 via a thread. A rotating sleeve 12 is movably inserted into the lower wall of the nut 11. A pressure plate 13 is installed at one end of the rotating sleeve 12 and is movably installed on the I-beam grid bar winding roller 1.

[0026] It should be noted that, through the cooperation of nut 11 and semi-threaded post 3, pressure plate 13 is pressed onto H-beam grid bar winding roller 1. When the steel-plastic grid bar is welded and laid out, H-beam grid bar winding roller 1 rotates. Under the friction between H-beam grid bar winding roller 1 and turntable 4, and between H-beam grid bar winding roller 1 and pressure plate 13, turntable 4 rotates on circular groove seat 2 and semi-threaded post 3. Pressure plate 13 drives rotating sleeve 12 to rotate on nut 11, which to a certain extent avoids severe wear between H-beam grid bar winding roller 1 and turntable 4, and between H-beam grid bar winding roller 1 and pressure plate 13.

[0027] As a preferred and further option, a guide rod 18 is installed on the groove 5, and the slider 6 is movably mounted on the guide rod 18 to guide the movement of the slider 6;

[0028] Preferably, and further, an enlarged block 19 is installed at one end of the movable column 16 inside the slot 15 to prevent the movable column 16 from detaching from the slot 15.

[0029] As a preferred and further option, an outer ring 20 is provided on the inner wall of the circular groove seat 2, and the turntable 4 is movably fitted on the outer ring 20; an inner ring 21 is provided on the outer wall of the semi-threaded column 3, and the turntable 4 is movably fitted on the outer ring 20; for movably supporting the turntable 4;

[0030] The pressing assembly is arranged in a circular array outside the circular groove seat 2. The spring 10 causes the slider 6 and the pressure roller 9 to radially press the outer ring grid strip of the winding roller, which prevents the grid strip from becoming loose or misaligned during welding or other processes, and prevents the grid strip from getting tangled with other equipment or components. This ensures that the wire feeding process is carried out in an orderly manner and avoids affecting the subsequent work of the grid strip.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
