Detailed Implementation
[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] Please see Figures 1-5 The present invention provides the following technical solution: a detachable safety guardrail device, including a guardrail body 2, multiple guardrail bodies 2 are set on the top of the storage tank 1 and enclose to form a closed or semi-closed protective area. The guardrail body 2 includes: a base 21, an adjustable column 22 with adjustable length, and a crossbar 23.
[0039] Furthermore, by Figure 1 As shown in this embodiment, the base 21 is fixed to the top of the storage tank 1, the bottom end of the adjustable column 22 is detachably connected to the base 21, and the crossbar 23 is detachably installed on the top of the adjustable column 22. After adopting the above solution, when using it, the staff needs to first confirm the installation point on the top of the storage tank 1, and firmly fix the base 21 of the guardrail body 2 to the preset point by means of bolts, welding or buckles (the fixing structure is adapted according to the material of the top of the storage tank 1), so as to ensure that the base 21 and the top of the storage tank 1 form a stable connection, providing a load-bearing foundation for the subsequent protective structure.
[0040] Subsequently, take out the adjustable column 22 with adjustable length, align its bottom end with the mounting position of the base 21 and detachably connect it to complete the assembly of the adjustable column 22 and the base 21; at this time, the extension length of the adjustable column 22 can be adjusted according to the protection height requirements of the top of the storage tank 1, so that multiple sets of adjustable columns 22 maintain a uniform height that meets safety standards, and avoid protection loopholes due to inconsistent heights.
[0041] Next, after completing the assembly of the crossbar 23 and the forming of the protective area, and after all the adjustable columns 22 are installed and adjusted in place, the crossbar 23 is detachably set on the top of the adjustable columns 22.
[0042] If the main body 2 of the guardrail is damaged during use (such as deformation of the crossbar 23 or loosening of the adjustable column 22), the staff can remove the crossbar 23 and the adjustable column 22 of the group separately for replacement without disassembling the whole, thus reducing maintenance costs and time. When the storage tank 1 needs to be relocated or modified, the crossbar 23 and the adjustable column 22 can be removed in sequence, leaving only the base 21, so as to avoid the guardrail device from obstructing the operation.
[0043] Optionally, by Figure 1 and Figure 3As shown, in this embodiment, the adjustable column 22 includes: a square tube 221, a square rod 222, and a first manual bolt 223. The bottom end of the square tube 221 is detachably connected to the base 21, and a square connecting cavity 2211 is provided inside the square tube 221. The square rod 222 is partially embedded in the square connecting cavity 2211 to form a telescopic structure. Multiple second positioning grooves 2221 are evenly spaced along the length of the square rod 222 on its outer wall. The first manual bolt 223 is installed on the square tube 221 by threaded engagement, and the end of the first manual bolt 223 is embedded in the second positioning groove 2221. The outer wall of the square rod 222 fits against the inner wall of the square connecting cavity 2211. With the above solution, during use… When the overall height of the adjustable column 22 needs to be adjusted, the operator must first operate the first manual bolt 223: Since the first manual bolt 223 is installed on the square tube 221 by thread, the first manual bolt 223 can be rotated clockwise so that its end gradually exits from the second positioning groove 2221 on the outer wall of the square rod 222 until the bolt end is completely disengaged from the second positioning groove 2221, releasing the locking state of the square rod 222. At this time, since the square rod 222 is only partially embedded in the square connecting cavity 2211 and the outer wall of the square rod 222 is tightly fitted with the inner wall of the square connecting cavity 2211, it can freely extend and retract along the axial direction of the square connecting cavity 2211 without locking constraints, providing room for height adjustment.
[0044] Secondly, based on the actual height requirements of the guardrail in the top protective area of storage tank 1, the staff can pull the square rod 222 upwards or downwards: when pulled upwards, the square rod 222 will gradually extend from the square connecting cavity 2211, and the overall height of the adjustable column 22 will increase accordingly; when pressed downwards, the square rod 222 will be further embedded into the square connecting cavity 2211, and the overall height will decrease accordingly. After the square rod 222 is adjusted to the target height, observe the second positioning groove 2221 on the outer wall of the square rod 222 to ensure that one of the second positioning grooves 2221 is on the same horizontal line as the first manual bolt 223 on the square tube 221, so as to prepare for subsequent locking.
[0045] Finally, the staff rotates the first manual bolt 223 counterclockwise. Using the pushing force of the thread engagement, the end of the first manual bolt 223 is gradually inserted into the corresponding second positioning groove 2221. The end of the first manual bolt 223 will tightly abut against the inner wall of the second positioning groove 2221, forming an axial lock, which restricts the extension and retraction of the square rod 222 in the square connecting cavity 2211, thereby fixing the adjustable column 22 at the target height.
[0046] Optionally, by Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the guardrail body 2 further includes: a U-shaped mounting base 24, a long bolt 25, a nut 26, and a second manual bolt 27. The U-shaped mounting base 24 is fixed to the outer wall of the base 21. The bottom end of the square tube 221 is embedded in the U-shaped mounting base 24. The long bolt 25 passes through the U-shaped mounting base 24 and the square tube 221. The nut 26 is installed on the protruding end of the long bolt 25 by thread engagement. The adjustable column 22 can rotate around the long bolt 25 as an axis. The second manual bolt 27 is installed on the U-shaped mounting base 24 by thread engagement. The outer wall of 221 is provided with a first positioning groove 2212 for the second manual bolt 27 to be inserted. The outer wall of the adjustable column 22 fits against the inner wall of the U-shaped mounting base 24. With the above scheme, when installing the adjustable column 22, the worker first aligns the bottom end of the square tube 221 with the opening end of the U-shaped mounting base 24 and slowly inserts it into the groove of the U-shaped mounting base 24. Since the outer wall of the adjustable column 22 (i.e. the outer wall of the square tube 221) fits tightly against the inner wall of the U-shaped mounting base 24, the position can be automatically calibrated during the insertion process, avoiding the square tube 221 from shifting in the groove.
[0047] Next, insert the long bolt 25 through the through hole on one side of the U-shaped mounting base 24, and pass through the two side walls of the U-shaped mounting base 24 and the pre-set shaft hole on the square tube 221 in sequence, until the protruding end of the long bolt 25 protrudes from the U-shaped mounting base 24; then install the nut 26 on the protruding end of the long bolt 25 by thread engagement, and tighten the nut 26 clockwise to make the long bolt 25 form a tight connection with the U-shaped mounting base 24 and the square tube 221.
[0048] After the adjustable column 22 is flipped upward to a vertical position, the second manual bolt 27 is rotated counterclockwise. Using the pushing force of the thread engagement, the end of the second manual bolt 27 is gradually inserted into the aligned first positioning groove 2212. The bolt is continuously tightened until its end is tightly abutted against the inner wall of the first positioning groove 2212, forming a lock. At this time, the tightening force of the second manual bolt 27 can restrict the square tube 221 from rotating around the long bolt 25.
[0049] If the guardrail device affects the handling of storage tank 1 during temporary handling, in addition to disassembling the guardrail device, the second manual bolt 27 can be unscrewed to flip the adjustable column 22 downwards until the adjustable column 22 is against the outer wall of storage tank 1, and the adjustable column 22 can be temporarily stored.
[0050] Optionally, by Figure 1 , Figure 3 and Figure 4As shown, this embodiment also includes: a square sleeve 231 and a third manual bolt 28. The square sleeve 231 is fixed to the bottom surface of the crossbar 23. The third manual bolt 28 is installed on the square sleeve 231 by thread engagement, and the end of the third manual bolt 28 is embedded in the second positioning groove 2221. The outer wall of the square rod 222 fits against the inner wall of the square sleeve 231. With the above solution, when installing the crossbar 23, the worker holds the crossbar 23, aligns the square sleeve 231 on its bottom surface with the top of the square rod 222, and puts the square sleeve 231 into the top of the square rod 222, so that the square rod 222 is partially embedded in the square sleeve 231. During this process, the fitted square structure can automatically limit the radial rotation of the crossbar 23, avoid the crossbar 23 from shifting or tilting when fitted, and ensure that the crossbar 23 and the adjustable column 22 remain perpendicular.
[0051] After the fitting is completed, the staff needs to confirm whether the height of the crossbar 23 meets the protection requirements. If the height of the crossbar 23 needs to be finely adjusted, the height adjustment process of the adjustable column 22 can be followed first until the crossbar 23 reaches the target height.
[0052] The second positioning groove 2221 corresponds to the mounting hole of the third manual bolt 28 on the square sleeve 231. The uppermost second positioning groove 2221 and the mounting hole of the third manual bolt 28 are on the same horizontal line. The operator rotates the third manual bolt 28 counterclockwise and uses the pushing force of the thread engagement to make the bolt end gradually embed into the corresponding second positioning groove 2221. The operator continues to tighten the third manual bolt 28 until its end is tightly abutted against the inner wall of the second positioning groove 2221, forming a lateral lock.
[0053] Components not described in detail in this article are existing technologies.
[0054] The working principle and usage process of this utility model: When using the guardrail device of this utility model, the staff needs to first confirm the installation point on the top of the storage tank 1, and then firmly fix the base 21 of the guardrail body 2 to the preset point by means of bolts, welding or buckles (the fixing structure is adapted according to the material of the top of the storage tank 1), so as to ensure that the base 21 and the top of the storage tank 1 form a stable connection, providing a load-bearing foundation for the subsequent protective structure.
[0055] Next, the guardrail body 2 is installed. The staff first aligns the bottom end of the square tube 221 with the opening end of the U-shaped mounting base 24 and slowly inserts it into the groove of the U-shaped mounting base 24. Since the outer wall of the adjustable post 22 (i.e. the outer wall of the square tube 221) is in close contact with the inner wall of the U-shaped mounting base 24, the position can be automatically calibrated during the insertion process to prevent the square tube 221 from shifting in the groove.
[0056] Next, insert the long bolt 25 through the through hole on one side of the U-shaped mounting base 24, and pass through the two side walls of the U-shaped mounting base 24 and the pre-set shaft hole on the square tube 221 in sequence, until the protruding end of the long bolt 25 protrudes from the U-shaped mounting base 24; then install the nut 26 on the protruding end of the long bolt 25 by thread engagement, and tighten the nut 26 clockwise to make the long bolt 25 form a tight connection with the U-shaped mounting base 24 and the square tube 221;
[0057] After the adjustable column 22 is flipped upward to the vertical position, the second manual bolt 27 is rotated counterclockwise. Using the pushing force of the thread engagement, the end of the second manual bolt 27 is gradually inserted into the aligned first positioning groove 2212. The bolt is continuously tightened until its end is tightly abutted against the inner wall of the first positioning groove 2212, forming a lock. At this time, the tightening force of the second manual bolt 27 can restrict the square tube 221 from rotating around the long bolt 25.
[0058] If the guardrail device affects the handling of storage tank 1 during temporary handling, in addition to disassembling the guardrail device, the second manual bolt 27 can be unscrewed and the adjustable column 22 can be flipped downwards until the adjustable column 22 is against the outer wall of storage tank 1, and the adjustable column 22 can be temporarily stored.
[0059] Then, based on the protection height requirements of the top of storage tank 1, the telescopic length of the adjustable column 22 is adjusted so that the multiple adjustable columns 22 maintain a uniform height that meets safety standards, thus avoiding protection loopholes due to inconsistent heights.
[0060] Finally, the crossbar 23 is installed. The worker holds the crossbar 23 and aligns the square sleeve 231 on its bottom surface with the top of the square bar 222. The square sleeve 231 is then inserted into the top of the square bar 222, so that the square bar 222 is partially embedded inside the square sleeve 231.
[0061] After the fitting is completed, the staff will confirm whether the height of the crossbar 23 meets the protection requirements. If the height of the crossbar 23 needs to be adjusted, the height adjustment process of the adjustable column 22 can be followed first until the crossbar 23 reaches the target height.
[0062] The second positioning groove 2221 corresponds to the mounting hole of the third manual bolt 28 on the square sleeve 231. The uppermost second positioning groove 2221 and the mounting hole of the third manual bolt 28 are on the same horizontal line. The operator rotates the third manual bolt 28 counterclockwise and uses the pushing force of the thread engagement to make the bolt end gradually embed into the corresponding second positioning groove 2221. The operator continues to tighten the third manual bolt 28 until its end is tightly abutted against the inner wall of the second positioning groove 2221, forming a lateral lock and completing the stable installation of the crossbar 23.
[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
