Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a sluice patrol guardrail structure. Background Art

[0002] A water conservancy project is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. It is also called a water project. Only by building a water conservancy project can we control the flow of water, prevent floods and waterlogging disasters, and regulate and distribute the amount of water to meet the people's needs for water resources for life and production. A water conservancy project requires the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts and fishways to achieve its goals.

[0003] The existing guardrails are inconvenient to install the horizontal bars, and the horizontal bars need to be installed one by one. When installing the horizontal bars, the connection parts of both ends of the horizontal bars and the pillars need to be carefully installed again, which has a long installation period and high installation cost.

[0004] For example, in the "guardrail for water conservancy project construction" disclosed in Chinese patent publication No. CN217353828U, a mounting block and a pull rod are used to fix one end of the cross bar, and the cross bar needs to be inserted into the mounting groove of the mounting block. Each installation of a cross bar requires two operations, resulting in a long installation period. Utility Model Content

[0005] The utility model aims to solve the above-mentioned shortcomings in the prior art and proposes a sluice patrol guardrail structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A sluice inspection guardrail structure is designed, including pillars and cross bars, wherein the pillars are at least two groups and slots are provided on the pillars, plug-in parts are fixedly provided on both sides of the cross bar, and the plug-in parts are respectively plugged into the slots on the two groups of pillars, a limit assembly for intermittently limiting the plug-in part is rotatably provided on the pillar, a fixing mechanism for fixing the limit assembly is provided on the pillar, a through groove matching the limit assembly is provided on the pillar, and the through groove is communicated with the slot.

[0008] Furthermore, the limiting assembly includes a semicircular member and a connecting plate fixedly connected to the semicircular member, and an extending portion for limiting the plug-in portion is provided on one side of the connecting plate.

[0009] Furthermore, a limit plate A is also provided on the connecting plate, a limit column matched with the limit plate A is fixedly provided at the lower end of the through slot, and a limit plate B matched with the limit column is fixedly provided on the semicircular member.

[0010] Furthermore, when the limiting assembly is in the initial state, the limiting plate B abuts against the limiting column;

[0011] After the limiting assembly rotates to the first preset angle, the limiting plate A abuts against the limiting column, and the extension portion is inserted into the slot to limit the crossbar that has not passed through.

[0012] Furthermore, the extension portion is a wedge-shaped extension portion, so that when the limit assembly is pressed down by the cross bar and rotated to the second preset angle, the extension portion is inserted between the two groups of cross bars to separate the two groups of cross bars. When the limit assembly continues to rotate to the first preset angle, the lower cross bar passes through, and the upper cross bar abuts against the extension portion.

[0013] Furthermore, the fixing mechanism includes a movable pin inserted on the pillar and connected to the limiting assembly, a spring connected to the movable pin is arranged in the pillar, and one end of the movable pin is provided with an inclined surface matching the limiting assembly.

[0014] The utility model provides a sluice inspection guardrail structure, which has the following beneficial effects:

[0015] In the utility model, the crossbar is fixed by the pillars, and the two ends of the crossbar are respectively inserted into the slots on the pillars to complete the installation steps. The crossbar naturally falls down to press the limit assembly to rotate, and the crossbar is separated by the extension part to form a guardrail structure.

[0016] Secondly, in the utility model, the limit assembly is fixed by a fixing mechanism, and when a group of cross bars come into contact with the limit assembly, the limit assembly is pressed to rotate, and after reaching a certain angle, the limit assembly abuts against the inclined surface on the movable pin, pressing the movable pin to move it backward, and when the limit assembly continues to rotate until the group of cross bars falls off, the movable pin pops out and is plugged into the limit assembly, fixing the limit assembly to prevent it from automatically resetting under the action of gravity, so as to limit the subsequent cross bars.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A sluice inspection guardrail structure includes pillars 1 and cross bars 2. There are at least two groups of pillars 1 and slots 3 are provided on the pillars 1. Insertion parts 4 are fixedly provided on both sides of the cross bars 2, and the insertion parts 4 are respectively inserted into the slots 3 on the two groups of pillars 1. A limiting component 5 for intermittently limiting the insertion part 4 is rotatably provided on the pillars 1. A fixing mechanism 6 for fixing the limiting component 5 is provided on the pillars 1. A through groove 7 cooperating with the limiting component 5 is provided on the pillars 1, and the through groove 7 is communicated with the slot 3.

[0024] In the utility model, the plug-in parts 4 at both ends of the cross bar 2 are respectively inserted into the slots 3 on the pillar 1, and then the cross bar 2 is pressed down or allowed to fall freely. When the cross bar 2 falls and contacts with the limit assembly 5, pressure is applied to the limit assembly 5 to make the limit assembly 5 rotate, so that the cross bar 2 continues to fall and hinders the subsequent cross bars 2 from falling, forming a guardrail structure.

[0025] Reference Figure 3 Furthermore, in the utility model, the limiting assembly 5 includes a semicircular member 51 and a connecting plate 52 fixedly connected to the semicircular member 51. An extension portion 53 for limiting the plug-in portion 4 is provided on one side of the connecting plate 52. When the cross bar 2 moves down and contacts the connecting plate 52, the limiting assembly 5 rotates, thereby allowing the cross bar 2 to fall smoothly and hinder the subsequent cross bar 2.

[0026] Reference Figure 3 In detail, in the utility model, a limit plate A54 is further provided on the connecting plate 52, a limit column 55 matched with the limit plate A54 is fixedly provided at the lower end of the through slot 7, and a limit plate B56 matched with the limit column 55 is fixedly provided on the semicircular member 51 to limit the rotation angle of the limit component 5 to prevent the rotation angle of the limit component 5 from exceeding a preset value and thus affecting the function of the limit component 5.

[0027] Reference Figure 3, in more detail, in the present utility model, when the limiting assembly 5 is in the initial state, the limiting plate B56 abuts against the limiting column 55 (not shown) to prevent the angle of the limiting assembly 5 from changing so that the connecting plate 52 cannot contact the crossbar 2;

[0028] After the limit assembly 5 rotates to the first preset angle, the limit plate A54 abuts against the limit column 55 to limit the limit assembly 5 to prevent its rotation from causing the subsequent cross bar 2 to fall, and the extension part 53 is inserted into the slot 3 to limit the cross bar 2 that has not passed through.

[0029] Reference Figure 3 In addition, in the present invention, the extension portion 53 is a wedge-shaped extension portion, so that when the limit assembly 5 is pressed down by the cross bar 2 and rotated to the second preset angle, the extension portion 53 is inserted between the two groups of cross bars 2 to separate the two groups of cross bars 2. When the limit assembly 5 continues to rotate to the first preset angle, the lower cross bar 2 passes through, and the cross bar 2 at the top abuts against the extension portion 53, thereby separating the two groups of cross bars 2 and passing only one group of cross bars 2 to form a guardrail structure with the two groups of pillars 1.

[0030] Reference Figure 4 Furthermore, the fixing mechanism 6 includes a movable pin 61 inserted on the pillar 1 and connected to the limiting portion 5. A spring 62 connected to the movable pin 61 is arranged in the pillar 1. One end of the movable pin 61 is provided with an inclined surface matching the limiting portion 5. When the limiting component 5 needs to pass through multiple groups of cross bars 2, it is only necessary to move the movable pin 61 outward to reset the limiting component 5, so that it can pass through multiple groups of cross bars 2.

[0031] Working method: When working, the plug-in parts 4 at both ends of the cross bar 2 are respectively inserted into the slots 3 on the pillar 1, and then the cross bar 2 is pressed down or allowed to fall freely. When the cross bar 2 falls to contact with the connecting plate 52, the limit assembly 5 rotates, so that the cross bar 2 falls smoothly. When the limit assembly 5 rotates to the second preset angle, the extension part 53 is inserted between the two groups of cross bars 2 to separate the two groups of cross bars 2. When the limit assembly 5 continues to rotate to the first preset angle, the lower cross bar 2 passes, and the cross bar 2 at the top abuts against the extension part 53, so that the two groups of cross bars 2 are separated and only one group of cross bars 2 is passed, forming a guardrail structure with the two groups of pillars 1. When the limit assembly 5 needs to pass through multiple groups of cross bars 2, it only needs to move the movable pin 61 outward to reset the limit assembly 5, so as to pass through multiple groups of cross bars 2.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
