Technical Field

[0001] The utility model belongs to the technical field of railway protection fences, and more specifically, particularly relates to a quick-installable and recyclable railway protection fence. Background Art

[0002] A railway fence is a structure installed along a railway line to ensure safety. It is usually made of metal or other strong materials and is used to prevent people or animals from entering the railway line to reduce accidents and casualties. These fences are usually installed on both sides of the railway line and are particularly important in railway stations, tunnels, bridges and other areas. Railway fences help reduce accidents and ensure the safety and smoothness of railway traffic.

[0003] When installing some current railway protective fences, two base columns are first fixed in a designated area, and then the protective net is fixed between the two base columns by bolts. This installation method requires the staff to use external force to align the protective net with the base columns and then screw the bolts in one by one. The work efficiency is low, especially when performing large-scale installation, it will consume a lot of time and manpower.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a quick-installed recyclable railway protective fence is provided, in order to achieve a more practical purpose. Utility Model Content

[0025] Example:

[0026] As attached Figure 1 To Attachment Figure 5 As shown:

[0027] The utility model provides a quick-install recyclable railway protective fence, comprising a pair of columns 1 and a protective fence body 2, the pair of columns 1 are symmetrically arranged, the pair of columns 1 are provided with a card slot 3 on the opposite side, a positioning column 4 is installed on one side of the card slot 3, the top of the positioning column 4 is provided with a first installation groove 5, the top of the first installation groove 5 is threadedly connected with a threaded block 6, and the top of the threaded block 6 extends to the outside of the positioning column 4, a connecting rod 7 is installed at the bottom end of the threaded block 6, and a plurality of trapezoidal blocks 8 are equidistantly installed on the circumference of the connecting rod 7, a plurality of second installation grooves 9 are symmetrically arranged on both sides of the positioning column 4, a ball 10 is installed in each second installation groove 9, and both sides of the ball 10 extend to the outside of the second installation groove 9, a pair of card columns 11 are symmetrically installed on both sides of the protective fence body 2, a pair of card columns 11 are provided with a positioning groove 12 on the opposite side, and a plurality of hemispherical grooves 13 are symmetrically arranged on both sides of the positioning groove 12.

[0028] Among them, the shape and size of the positioning column 4 match the shape and size of the positioning groove 12. When installing the protective fence body 2 between a pair of columns 1, the staff first aligns the positions of the pair of positioning grooves 12 with the positions of the pair of positioning columns 4, so that the positioning grooves 12 are located directly above the positioning columns 4, and then moves the protective fence body 2 downward. Since the shape and size of the positioning column 4 match the shape and size of the positioning groove 12, the card column 11 will slide downward in the card slot 3 to the bottom end, thereby realizing the preliminary fixation between the protective fence body 2 and the pair of columns 1.

[0029] Among them, the positions of several trapezoidal blocks 8 match the positions of several balls 10. After the clamping column 11 is inserted into the clamping slot 3, the threaded block 6 is rotated by rotating the knob 14, and then the trapezoidal block 8 is driven to move downward, so that one side of the trapezoidal block 8 can be tightly attached to one side of the ball 10 and push the ball 10 away from the first mounting groove 5, so that the ball 10 can be fixed on one side of the second mounting groove 9.

[0030] Among them, the positions and sizes of several balls 10 match the positions and sizes of several hemispherical grooves 13. When the trapezoidal block 8 squeezes the balls 10 outward, since the positions and sizes of the balls 10 match the positions and sizes of the hemispherical grooves 13, one side of the balls 10 enters into the hemispherical grooves 13, thereby fixing the railway protective fence body 2.

[0031] Among them, a knob 14 is installed on the top of the threaded block 6. By rotating the knob 14, the threaded block 6 is driven to rotate in the first installation groove 5, and then the connecting rod 7 drives the plurality of trapezoidal blocks 8 to move up and down to achieve the limitation of the ball 10.

[0032] Among them, an anti-skid pad 15 is installed at the bottom end of the knob 14, which improves the stability when the knob 14 is rotated to the bottom end, reduces shaking and loosening, and further improves the overall stability of the railway protection fence.

[0033] Among them, an inclined baffle 16 is installed on the top of the protective fence body 2 to prevent pedestrians from forcibly climbing over the fence.

[0034] The working principle of this embodiment: when installing the railway protective fence, the staff first installs a pair of columns 1 to the position where they need to be installed, and adjusts the spacing between the pair of columns 1, then takes out the protective fence body 2, aligns the position of the pair of positioning grooves 12 with the position of the pair of positioning columns 4, so that the positioning grooves 12 are located directly above the positioning columns 4, and then moves the protective fence body 2 downward. Since the shape and size of the positioning columns 4 match the shape and size of the positioning grooves 12, the clamping column 11 will slide downward in the clamping groove 3 until the bottom end, thereby achieving the initial fixation between the protective fence body 2 and the pair of columns 1, and then rotates the knob 14 to drive the threaded block 6 to move downward in the first mounting groove 5, thereby driving the trapezoidal block 8 to move downward. During the descent of the trapezoidal block 8, the inclined surface at the bottom end of the trapezoidal block 8 first contacts the ball 10, pushing the ball 10 away from the first mounting groove 5, and then one side of the trapezoidal block 8 is in close contact with the ball 10, so that the ball 10 can be fixed on one side of the second mounting groove 9. When After the trapezoidal block 8 extrude the ball 10 outward, since the position and size of the ball 10 match the position and size of the hemispherical groove 13, one side of the ball 10 enters the hemispherical groove 13 to fix the railway protective fence body 2. At this time, the knob 14 rotates to the lowest point, and the anti-slip pad 15 fits with the top of the positioning column 4, increasing the friction between the knob 14 and the positioning column 4, and reducing the loosening of the knob 14. When the railway protective fence needs to be disassembled for maintenance, the staff rotates the knob 14 to drive the trapezoidal block 8 to rise through the threaded block 6 and the connecting rod 7. At this time, the ball 10 is no longer limited by the trapezoidal block 8. When the staff pushes the protective fence body 2 upward, the ball 10 is squeezed by the hemispherical groove 13 and moves in the second mounting groove 9 toward the direction of the first mounting groove 5, and then no longer has a limiting effect on the protective fence body 2, which is convenient for the staff to take out the protective fence body 2, wherein the inclined baffle 16 at the top of the protective fence body 2 can prevent pedestrians from forcibly climbing over the fence.

[0035] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.
