TECHNICAL FIELD
[0001] The utility model relates to safety warning protection equipment technical field, specifically relates to a safety guardrail. BACKGROUND
[0002] In the production process of coating equipment, usually, the limited space of underground part is involved, such as the closed or semi-closed underground pipe gallery with narrow entrance and exit and poor ventilation, which is not as a fixed work place, but when maintenance, cleaning or inspection work, personnel need to enter and as a temporary work place. At present, protective fences are usually installed to prevent personnel from falling, and to inform other personnel that there is personnel working in the current limited space during maintenance.
[0003] However, the protective fence for limited space operation is usually too simple and cannot be adjusted according to actual needs, and only the openable fence assembly is used. Based on this, the Chinese invention patent document (CN107012811B) discloses a safety fence, which comprises a support frame, a main support, a telescopic frame and a stabilizing support. By setting the telescopic frame, the fence can be stretched outward according to the actual needs, thereby increasing the length of the fence, without the need to additionally add a fence, and the operation is simple. When the telescopic frame is not needed, it can be collected in the main support.
[0004] However, it is more suitable for temporary work places such as railway construction, and for limited space operation of underground part, the extendable function is redundant, and it does not have warning function. That is, there is still an urgent need for a safety fence that can be used for temporary operation in limited space. UTILITY MODEL CONTENT
[0005] The utility model provides a kind of safety guardrail to solve the problem of lack of suitable safety guardrail in prior art when limited space temporary operation.
[0006] To solve the above technical problems, the utility model adopts the technical scheme to provide a kind of safety guardrail, and the safety guardrail includes: guardrail main body, fixed part, rod and warning sleeve.
[0007] The guardrail main body includes first guardrail main body and second guardrail main body spaced apart along the first direction, and an access passage is provided between the first guardrail main body and the second guardrail main body;The fixed part is fixed to the first guardrail main body;The rod includes a straight blocking part and a bent part connected by rotation, wherein the bent part is fixed to the fixed part, and the straight blocking part extends along the first guardrail main body to the second guardrail main body;The warning sleeve is sleeved on one side of the straight blocking part close to the second guardrail main body.
[0008] The technical scheme provided by the utility model has the beneficial effects compared with prior art:
[0009] The guardrail body and the blocking rail are arranged to achieve the protection function, so as to prevent the staff from falling, and the blocking rail can be opened and closed to facilitate the staff to open the rail to enter the limited space for work. The opening and closing of the blocking rail is realized by the straight blocking part and the bent part connected by rotation, that is, when the staff needs to open the blocking rail, the lever principle is used to realize the opening and closing by taking the fixed part of the first guardrail body as the supporting point.
[0010] In addition, the blocking rail is further sleeved with a warning sleeve, so that the staff can determine the state of the limited work space through the warning sleeve. When the staff needs to open the blocking rail to enter the limited space through the access channel, the warning sleeve is located at the force position of the staff, so as to ensure that the staff can discover the warning information of the warning sleeve in time. Compared with the safety guardrail currently used for railway construction work, the above-mentioned guardrail structure is simpler and more convenient to open and close, and is more suitable for underground limited space.
[0011] In some embodiments, the second guardrail body is further provided with a pad, and one side of the straight blocking part of the warning sleeve can be placed on the pad in a second direction.
[0012] Since the safety guardrail is usually applied to the limited work of underground space, that is, the staff's movable space is usually small, by using the above technical solution, the blocking rail is directly placed on the pad, and the straight blocking part and the bent part of the blocking rail are rotated to realize the opening and closing of the access space, so as to reduce the difficulty of closing the blocking rail after the staff enters the access channel, and the pad can also buffer the blocking rail.
[0013] In some embodiments, the warning sleeve includes a plurality of display colors, and the warning sleeve can be rotated clockwise or counterclockwise around the blocking rail, so that the required display color can be located on the outside of the first guardrail body.
[0014] By using the above technical solution, the warning sleeve is provided with a plurality of display colors, so that the staff can determine whether there is a person working in the limited space through the current display color.
[0015] Further, the warning sleeve is a rubber sleeve. The rubber material has good wear resistance and impact resistance, and the rubber material warning sleeve can maintain a relatively bright color in long-term use and tightly fit the blocking rail.
[0016] In some embodiments, the display colors of the warning sleeve include red and green. Generally, the limited space mainly includes a person state and a no person state, in order to facilitate other staff to quickly identify the work situation in the limited space, red can be set as the "person working" state, and green can be set as the "no person working" state.
[0017] In some embodiments, the fixing part comprises a first U-shaped clamp, a fixing sheet and a second U-shaped clamp, the first U-shaped clamp and the second U-shaped clamp are arranged in a second direction with a spacing, and the fixing sheet is connected to the first U-shaped clamp and the second U-shaped clamp respectively.
[0018] By arranging the first U-shaped clamp and the second U-shaped clamp, the fixing sheet can be installed flexibly, that is, by adjusting the spacing between the first U-shaped clamp and the second U-shaped clamp, different specifications of the fixing sheet can be replaced, or by adjusting the height at which the first U-shaped clamp and the second U-shaped clamp are fixed to the first guardrail main body, the installation height of the barrier rod can be adjusted, thereby facilitating the quick installation and adjustment of the safety guardrail in different terrains and working scenarios.
[0019] In some embodiments, the bending part is a lead screw, the fixing sheet further comprises a first fixing member and a second fixing member connected to the bending part respectively, and the first fixing member and the second fixing member are arranged in a second direction with an inclination.
[0020] By using the lead screw structure for the bending part, the lead screw structure can provide good self-locking performance and anti-loosening performance for the barrier rod, and the use and maintenance cost of the lead screw structure is relatively low, which is more suitable for use in limited space. In addition, the lead screw structure cooperates with the first fixing member and the second fixing member arranged with an inclination, which can better adapt to the installation requirements of different angles and heights of the barrier rod.
[0021] In some embodiments, the cushion block is further provided with a third U-shaped clamp at the lower end in the second direction, and the third U-shaped clamp is sleeved on the first guardrail main body. By fixing the installation height of the cushion block through the third U-shaped clamp, the installation height of the cushion block can be adjusted accordingly when the height of the barrier rod is adjusted.
[0022] In some embodiments, the first guardrail main body and / or the second guardrail main body comprises a wall. In some application scenarios, the wall can also serve as the fixing base of the safety guardrail.
[0023] In some embodiments, the access passage further comprises a staircase. In some application scenarios, the access passage is located at the edge of the corridor, and the staircase is arranged to facilitate the access of the staff to the restricted space through the staircase, which cooperates with the safety guardrail structure to ensure the safety of the work area.

DETAILED DESCRIPTION
[0033] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0034] In order to facilitate the subsequent description, before describing the specific structure of the safety fence, the present application first combinesFigure 1 A first direction (X) and a second direction (Z) are defined. The first direction is the width direction of the safety fence when it is normally placed, for example, the X direction. The second direction is the height direction of the safety fence when it is normally placed, for example, the Z direction. In this application, the first direction (X) and the second direction (Z) are perpendicular to each other. It can be understood that the perpendicular in this application is not absolute, and the approximate perpendicular (for example, the included angle between two structural features is 89.9°) caused by processing errors and assembly errors is also within the scope of the perpendicular in this application.
[0035] Referring to Figure 1 as shown, Figure 1 A front view of an embodiment of a safety fence provided by the present application is shown.
[0036] In some embodiments, the safety fence comprises a fence body 10, a fixed part 20, a blocking rod 30 and a warning sleeve 40. The fence body 10 comprises a first fence body 11 and a second fence body 12 arranged at intervals along the first direction, and an access passage 13 is arranged between the first fence body 11 and the second fence body 12; the fixed part 20 is fixed to the first fence body 11; the blocking rod 30 comprises a straight blocking part 31 and a bent part 32 connected by rotation, wherein the bent part 32 is fixed to the fixed part 20, and the straight blocking part 31 extends along the first fence body 11 to the second fence body 12; the warning sleeve 40 is sleeved on one side of the straight blocking part 31 close to the second fence body 12.
[0037] In the embodiment of the present application, the fence body and the blocking rod 30 that blocks the access passage 13 are arranged to achieve the protection function, preventing the staff from falling, and at the same time, the blocking rod 30 can be opened and closed to facilitate the staff to open the fence to enter the restricted space for work. As shown in Figure 1 in some application scenarios, the access passage 13 is located at the edge of the corridor, and the access passage 13 is provided with a staircase 130 for facilitating the staff to enter and exit the restricted space, which cooperates with the safety fence structure to ensure the safety of the work area. Wherein, the access passage 13 can also be used as a path towards the restricted work space.
[0038] Wherein, the opening and closing of the blocking rod 30 is realized by the straight blocking part 31 and the bent part 32 connected by rotation, that is, when the staff needs to open the blocking rod 30, the lever principle can be used to realize the opening and closing by taking the fixed part 20 of the first fence body 11 as the support point. As shown in
[0039] In addition, a warning sleeve 40 is fitted onto the lever 30, allowing workers to determine the current status of the restricted work space through the warning sleeve 40. Furthermore, when workers need to open the lever 30 to enter the restricted space through the access passage 13, the warning sleeve 40 is positioned at the worker's hand position, ensuring that workers can promptly detect the warning information from the warning sleeve 40.
[0040] In some implementations, the second guardrail body 12 is also provided with a pad 120, wherein the side of the straight stop 31 covered with the warning sleeve 40 can rest on the pad 120 in the second direction.
[0041] Since this safety barrier is typically used for restricted operations in underground spaces, where the space available for workers is usually limited, in this embodiment, the barrier 30 is directly supported by a pad 120. The opening and closing of the barrier 30 for entering and exiting the space is achieved by rotating the straight stop 31 and the bent part 32 of the barrier 30. This reduces the difficulty for workers to close the barrier 30 after entering or exiting the passage 13, and the pad 120 also provides cushioning for the barrier 30. In some applications, the pad 120 can also be connected to a warning light to detect whether the barrier 30 is placed on the pad 120.
[0042] See Figures 2 to 3 As shown, Figure 2 A top view of an embodiment of a safety guardrail provided in this application is shown. Figure 1 ; Figure 3 A top view of an embodiment of a safety guardrail provided in this application is shown. Figure 2 ;in, Figure 3 The middle gear lever 30 is in the closed position. Figure 2 The middle gear lever 30 is in the open position.
[0043] In some application scenarios, when workers need to enter a confined space for work, they can raise the barrier lever 30 and rotate it by a corresponding angle, so that the barrier lever 30 is... Figure 3 Status switch to Figure 3 Status, so that staff can follow Figure 4 Enter through passage 13 in the direction of the arrow shown, and then enter the restricted space via staircase 130.
[0044] In some implementation schemes, combined Figure 4 As shown, Figure 4 A schematic diagram of an embodiment of a warning sleeve 40 for a safety guardrail provided in this application is shown.
[0045] In some implementations, the warning sleeve 40 includes multiple display colors, wherein the warning sleeve 40 is rotatable clockwise or counterclockwise around the guardrail 30 so that the desired display color can be located on the outside of the first guardrail body 11.
[0046] In this embodiment of the application, by setting multiple display colors for the warning sleeve 40 (e.g., blue for maintenance status, yellow for upkeep status, red for current personnel operation status, etc.), the staff can determine the operation status of the restricted space by the current display color. In this application, the color of the warning sleeve 40 is not limited. For example, the display color can be determined by the actual application scenario and employee training to achieve the warning purpose.
[0047] For example, the display colors of the warning sleeve 40 include red and green. (As...) Figure 2 The shaded area A represents green, and the shaded area B represents red. Generally, confined spaces are either occupied or unoccupied. To facilitate quick identification of work status within the confined space by other personnel, red can be designated as "occupied" and green as "unoccupied".
[0048] Furthermore, the warning sleeve 40 is a rubber sleeve. The rubber material has good wear resistance and impact resistance, and the rubber warning sleeve 40 can maintain a relatively bright color during long-term use and fits tightly against the stop lever 30.
[0049] Combination Figure 5 and Figure 5 As shown, Figure 6 This illustration shows an application scenario diagram of an embodiment of a safety barrier provided in this application. Exemplarily, the restricted space can be a maintenance passageway space equipped with various devices. When staff need to maintain the equipment within this restricted space, they can open the barrier 30 and enter the maintenance space via the stairs 130. Specifically, when staff open the barrier 30, they need to rotate the display color of the warning sleeve (e.g., change the color from green to red), enter the stairs 130, and then place the barrier 30 on the pad 120.
[0050] In some implementation schemes, the first guardrail body 11 or the second guardrail body 12 includes a wall. In some application scenarios, the wall can also serve as the fixed foundation for the aforementioned safety guardrail.
[0051] See Figure 6 As shown, A partial structural schematic diagram of an embodiment of the fixing part 20 of a safety guardrail provided in this application is shown.
[0052] In some embodiments, the fixing part 20 includes a first U-shaped card 21, a fixing piece 22, and a second U-shaped card 23. The first U-shaped card 21 and the second U-shaped card 23 are spaced apart along a second direction, and the fixing piece 22 is connected to the first U-shaped card 21 and the second U-shaped card 23 respectively.
[0053] In the embodiments of the present application, the U-shaped clamps are fixing clamps made of metal material and similar to the letter "U". When they are applied to the installation of the fixing plates 22, the interval distance between the first U-shaped clamp 21 and the second U-shaped clamp 23 can be adjusted to replace fixing plates 22 of different specifications, or the height of the first U-shaped clamp 21 and the second U-shaped clamp 23 fixed to the first guardrail main body 11 can be adjusted to adjust the installation height of the barrier rod 30, so that the above-mentioned safety guardrail can be quickly installed and adjusted and adapted to different terrains and working scenes.
[0054] In some embodiments, the cushion block 120 is further provided with a third U-shaped clamp 121 at the lower end in the second direction, and the third U-shaped clamp 121 is sleeved on the first guardrail main body 11. The third U-shaped clamp 121 is used to fix the installation height of the cushion block 120, so that the installation height of the cushion block 120 can be adjusted when the height of the barrier rod 30 is adjusted.
[0055] In some embodiments, the fixing plate 22 further comprises a first fixing piece 220 and a second fixing piece 221 connected with the bent part 32 respectively, and the first fixing piece 220 and the second fixing piece 221 are arranged obliquely in the second direction.
[0056] In the embodiments of the present application, the screw rod structure cooperates with the obliquely arranged first fixing piece 220 and the second fixing piece 221, so that the installation requirements of different angles and heights of the barrier rod 30 can be better met.
[0057] The above-mentioned is only the implementation manner of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation by using the content of the present application specification and drawings, or direct or indirect application in other related technical fields should be carried in the protection range of the present application.
