Description

Technical Field

[0001] The utility model relates to a guardrail unit, in particular to an assembled guardrail unit. Background Art

[0002] Railways, highways or slopes usually adopt guardrails for interception and isolation to achieve the function of safety protection. Traditional guardrails generally have a tight shielding structure. Although they can prevent all people or animals from passing through, such guardrails are airtight and have a large wind resistance when encountering bad weather such as strong winds, so they are prone to breakage and damage.

[0003] The utility model patent with the publication number CN213142882U discloses a traffic guardrail that is easy to disassemble and assemble. It is composed of a plurality of guardrail components spliced together. The guardrail components include an upper cross bar, a lower cross bar and a plurality of vertical bars arranged between the upper cross bar and the lower cross bar. There is enough clearance between two adjacent vertical bars in this guardrail, so it has good air permeability, can allow air to flow smoothly, has a small wind resistance, and reduces the risk of breakage and damage.

[0004] However, the traffic guardrail in the above patent can only block large and medium-sized animals, while small animals can still pass through between the two vertical bars at the bottom of the guardrail. Therefore, it cannot effectively intercept small animals. Summary of the Utility Model

[0005] In order to solve the above deficiencies in the prior art, the utility model aims to provide an assembled guardrail unit to achieve the purpose of reducing wind resistance and intercepting large, medium and small animals.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An assembled guardrail unit includes a first vertical column and a second vertical column arranged at intervals. An upper cross beam and a lower cross beam are fixedly arranged between the first vertical column and the second vertical column. The upper cross beam and the lower cross beam are arranged at intervals. A plurality of vertical bars are detachably arranged between the upper cross beam and the lower cross beam. There is a clearance between two adjacent vertical bars; a baffle is fixedly arranged at the position of each vertical bar close to the lower cross beam. The clearance size between two adjacent baffles is smaller than the clearance size between two adjacent vertical bars.

[0008] As a limitation of the utility model: a connecting sleeve is arranged between the baffle and the vertical bar. The connecting sleeve includes a first connecting block, a second connecting block and a third connecting block fixedly connected in sequence. The second connecting block is fixedly sleeved on the vertical bar;

[0009] The baffle includes a first blocking rod and a second blocking rod. The first blocking rod and the second blocking rod are both arranged parallel to the vertical bar. The first blocking rod is fixedly sleeved in the first connecting block, and the second blocking rod is fixedly sleeved in the third connecting block;

[0010] The gap size between the first retaining rod and the second retaining rod located between two adjacent vertical rods is smaller than the gap size between two adjacent vertical rods.

[0011] As a further limitation to the present utility model: The longitudinal section of the connecting sleeve is in a Z shape.

[0012] As another limitation to the present utility model: The upper cross beam and the lower cross beam have the same structure, and the detachable connection methods between the vertical rod and the upper cross beam, and between the vertical rod and the lower cross beam are the same;

[0013] The longitudinal section of the upper cross beam is in a U shape, and its U-shaped opening faces the lower cross beam. A plurality of fixing components are arranged at intervals along the length direction in the U-shaped groove of the upper cross beam. The fixing component includes a rotating shaft and a plug block fixedly connected. The rotating shaft is rotatably connected to the upper cross beam, and a slot for matching with the plug block is arranged on the vertical rod.

[0014] As a further limitation to the present utility model: A pair of cross plates are slidably arranged in the U-shaped groove of the upper cross beam. The sliding direction of the cross plates is along the length direction of the upper cross beam. The fixing components are arranged between the two cross plates, and the rotating shaft is rotatably connected to the two cross plates.

[0015] As a further limitation to the present utility model: End caps for sealing are arranged at the tops of the first vertical column and the second vertical column.

[0016] As another limitation to the present utility model: A steering part for changing the connection angle between two adjacent guardrail units is arranged on the first vertical column and / or the second vertical column. The steering part includes a base fixedly connected to the second vertical column and a rotating block fixedly connected to the first vertical column; a rotating head is arranged on the rotating block, and a clamping groove for matching with the rotating head is arranged on the base.

[0017] Due to the adoption of the above technical solutions, compared with the prior art, the beneficial effects obtained by the present utility model are:

[0018] The present utility model includes a first vertical column and a second vertical column arranged at intervals. An upper cross beam and a lower cross beam are fixedly arranged between the first vertical column and the second vertical column. A plurality of vertical rods are detachably arranged between the upper cross beam and the lower cross beam. There is a gap between two adjacent vertical rods, which has good air permeability, can reduce wind resistance, and avoid damage to the guardrail unit caused by too large wind resistance in strong wind weather. At the same time, the guardrail unit can also intercept large and medium-sized animals;

[0019] A baffle is fixedly arranged at the position of each vertical rod close to the lower cross beam.

[0042] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and do not constitute a limitation to the present invention.

[0043] The orientation terms or positional relationships such as "upper", "lower", "left", "right", "front", "rear", etc. described in the embodiments are based on the orientation relationships in the drawings of the specification of the present invention Figure 1 merely for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the content protected by the present invention.

[0044] As Figures 1 to 13 shown, this embodiment includes a first column 1 and a second column 2 arranged at intervals. An upper cross beam 3 and a lower cross beam 4 are fixedly provided between the first column 1 and the second column 2. The upper cross beam 3 and the lower cross beam 4 are arranged at intervals. A plurality of vertical rods 5 are detachably arranged between the upper cross beam 3 and the lower cross beam 4, and there is a gap between adjacent two vertical rods 5; a baffle 6 is fixedly provided at the position of each vertical rod 5 close to the lower cross beam 4, and the gap size between adjacent two baffles 6 is smaller than the gap size between adjacent two vertical rods 5. In this embodiment, the wind can pass through between adjacent two vertical rods 5 and adjacent two baffles 6, having good air permeability; and the gap size between adjacent two baffles 6 is smaller, which can intercept small animals and prevent small animals from passing through the bottom of the guardrail.

[0045] I. Vertical rod 5, baffle 6;

[0046] As Figure 1 shown, a plurality of vertical rods 5 are provided, and the plurality of vertical rods 5 are arranged in parallel. The vertical rod 5 is a cubic rod-shaped structure, and there is a gap between adjacent two vertical rods 5, and this gap is the first gap 12. The size of the first gap 12 is relatively large, having good air permeability.

[0047] The baffle 6 is fixedly arranged at the position of the vertical rod 5 close to the lower cross beam 4, that is, the baffle 6 is fixedly arranged on the lower half section of the vertical rod 5, aiming to prevent small animals from passing through the bottom of the guardrail.

[0048] A connecting sleeve 7 is arranged between the baffle 6 and the vertical rod 5. As Figure 1 , 7 shown, in this embodiment, two connecting sleeves 7 are arranged on each vertical rod 5. Taking the connecting sleeve 7 at the upper position as an example, as Figure 8 shown, the connecting sleeve 7 includes a first connecting block 71, a second connecting block 72 and a third connecting block 73 that are fixedly connected in sequence from left to right. Through grooves are provided at the middle positions of the first connecting block 71, the second connecting block 72 and the third connecting block 73. The second connecting block 72 is fixedly sleeved on the vertical rod 5. Refer to Figure 7 .

[0049] As Figure 1 , 7 , 8, 9 shown, the baffle 6 includes a first baffle rod 61 and a second baffle rod 62. The first baffle rod 61 and the second baffle rod 62 are both arranged parallel to the vertical rod 5. The first baffle rod 61 is fixedly sleeved in the first connecting block 71, and the second baffle rod 62 is fixedly sleeved in the third connecting block 73. After being fixed, the first baffle rod 61 is located on the left side of the vertical rod 5, and the second baffle rod 62 is located on the right side of the vertical rod 5. At this time, the gap between two adjacent baffles 6 specifically refers to the gap between the first baffle rod 61 and the second baffle rod 62 located between two adjacent vertical rods 5. Refer to Figure 1 , and this gap is the second gap 13. The size of the second gap 13 is smaller than the size of the first gap 12, which is convenient for intercepting small animals and still has a certain air permeability.

[0050] To improve this embodiment, as Figure 8 shown, the longitudinal section of the connecting sleeve 7 is in a Z shape. In other words, the first connecting block 71 and the third connecting block 73 are fixedly arranged on both sides of the second connecting block 72 and are offset in the front-back direction, so that the longitudinal section of the connecting sleeve 7 is in a Z shape. This structure is for the purpose of being able to install this embodiment smoothly on a slope as well. When installing on a slope, the upper cross beam 3 and the lower cross beam 4 need to be parallel to the slope, but the first upright post 1, the second upright post 2 and the vertical rod 5 still need to be installed vertically. At this time, the vertical rod 5 and the lower cross beam 4 are not in a vertical state. The first connecting block 71 and the third connecting block 73 are offset in the front-back direction, so that the first baffle rod 61 and the second baffle rod 62 located between two adjacent vertical rods 5 are also in an offset state. Refer to Figure 13 , which can avoid the first baffle rod 61 and the second baffle rod 62 located between two adjacent vertical rods 5 from abutting against each other and being difficult to install when installing on a slope. Of course, if installed on flat ground, the connecting sleeve 7 can also be set in a straight shape.

[0051] II. Upper cross beam 3, fixing component 8;

[0052] The upper crossbeam 3 and the lower crossbeam 4 are arranged at intervals and in parallel, and the upper crossbeam 3 and the lower crossbeam 4 have the same structure. Each vertical pole 5 is detachably connected to the upper crossbeam 3 and the lower crossbeam 4. Taking the connection between the vertical pole 5 and the upper crossbeam 3 as an example for illustration:

[0053] As Figure 2 , 4 shown, the longitudinal section of the upper crossbeam 3 is U-shaped, and its U-shaped opening faces the lower crossbeam 4. A pair of cross plates 11 are slidably arranged in the U-shaped groove 31 of the upper crossbeam 3. Specifically, both ends of the U-shaped opening are bent inwardly towards the inside of the upper crossbeam 3 to form bent ends. A limiting strip 32 is arranged at the bottom of the U-shaped groove 31 corresponding to the bent ends. The bent ends and the limiting strip 32 are used for clamping the cross plates 11. In this embodiment, two mutually parallel cross plates 11 are clamped in the U-shaped groove 31 of the upper crossbeam 3. The cross plates 11 are long and thin plates, and their sliding direction is arranged along the length direction of the upper crossbeam 3.

[0054] As Figure 2 , 5 shown, a plurality of fixing components 8 are arranged at intervals along the length direction in the U-shaped groove 31 of the upper crossbeam 3. Here, the length direction refers to the left and right directions. Specifically, the fixing components 8 are arranged between the two cross plates 11. As Figure 3 shown, the fixing component 8 includes a rotating shaft 81 and an inserting block 82 which are fixedly connected. The rotating shaft 81 is a cylindrical structure, and its axial direction is arranged along the front and back directions. The front and rear ends of the rotating shaft 81 are respectively rotatably connected to the corresponding cross plates 11. The inserting block 82 is used for inserting into the vertical pole 5. The purpose of the rotational connection is to adapt to the terrain with a slope. When installed on flat ground, the vertical pole 5 and the upper crossbeam 3 are in a vertical state. However, on the terrain with a slope, the upper crossbeam 3 needs to be inclined along with the terrain, but the vertical pole 5 still needs to be installed vertically. In this structure, the vertical pole 5 is fixedly connected to the fixing component 8, and the fixing component 8 is rotatably connected to the upper crossbeam 3. Then the vertical pole 5 can rotate relative to the upper crossbeam 3, so that the vertical pole 5 is always in a vertical state.

[0055] As Figure 6 , 7 shown, the inside of the vertical pole 5 is hollow to form a slot 51, and the slot 51 is adapted to the inserting block 82. Here, being adapted means that the size of the slot 51 is equal to or slightly smaller than the size of the inserting block 82 to ensure that the inserting block 82 is inserted into the slot 51 to realize the fixation of the vertical pole 5 and the cross plate 11.

[0056] The way of the rotational connection between the rotating shaft 81 and the cross plate 11 is that, as Figure 2 shown, a through hole with a diameter slightly larger than the outer diameter of the rotating shaft 81 is opened on the cross plate 11 corresponding to the position of the rotating shaft 81, and the width of the U-shaped groove 31 is equal to the axial length of the rotating shaft 81. Here, the width refers to the dimension in the front and back directions, so that the end of the rotating shaft 81 contacts the inner wall of the U-shaped groove 31, ensuring that the rotating shaft 81 will not come out of the through hole and can still rotate relative to the cross plate 11.

[0057] In this embodiment, the purpose of setting the cross plate 11 is that after the vertical poles 5 are fixed to the cross plate 11 one by one, the vertical poles 5 and the cross plate 11 can be slid left and right together, so that the installation position is more accurate. Of course, if it is not necessary to slide the cross plate 11, the rotating shaft 81 can be directly rotatably connected to the upper cross beam 3.

[0058] The connection mode between the vertical pole 5 and the lower cross beam 4 is the same as that between the vertical pole 5 and the upper cross beam 3. Refer to Figure 10 , and details are not described here again.

[0059] III. The first upright column 1, the second upright column 2, and the end cover 10;

[0060] As Figure 1 shown, the first upright column 1 and the second upright column 2 are arranged at intervals and in parallel. There are two upper and lower connectors 14 fixed on each of the first upright column 1 and the second upright column 2. The connectors 14 are fixedly sleeved on the first upright column 1 or the second upright column 2. The connectors 14 are fixed to the upper cross beam 3 and the connectors 14 are fixed to the lower cross beam 4 by screws. The connectors 14 are prior art, and the structure thereof is not described in detail in this embodiment.

[0061] As Figure 1 , 5 shown, end covers 10 for sealing are provided at the tops of the first upright column 1 and the second upright column 2, and the appearance is more beautiful.

[0062] IV. The steering part 9;

[0063] As Figure 1 shown, a steering part 9 for changing the connection angle between adjacent two guardrail units is provided on the first upright column 1 and / or the second upright column 2 to adapt to the installation on a slope. As Figure 11 , 12 shown, the steering part 9 includes a base 91 fixedly connected to the second upright column 2 in one of the guardrail units, and a rotating block 92 fixedly connected to the first upright column 1 in another guardrail unit; the rotating block 92 is a cubic structure, a spherical rotating head 921 is provided on the rotating block 92, and a card slot 911 adapted to the rotating head 921 is provided on the base 91. Here, being adapted means that the rotating head 921 can be inserted into the base 91 and can rotate in multiple directions, similar to a universal ball in the prior art.

[0064] When using this embodiment, drill holes at the positions corresponding to the first upright column 1 and the second upright column 2 on the ground to pour concrete foundations, fix the first upright column 1 and the second upright column 2, insert and fix a plurality of vertical poles 5 to the upper cross beam 3 and the lower cross beam 4 respectively through the fixing assembly 8, and then fix the upper cross beam 3 and the lower cross beam 4 to the first upright column 1 and the second upright column 2 through the connectors 14.

[0065] If this embodiment is installed on the slope body, first insert a number of vertical rods 5 into the inserts 82 on the lower cross beam 4 in sequence. Since the rotating shaft 81 is rotatably connected to the cross plate 11, it can ensure that the vertical rods 5 are in a vertical state after installation. Then insert and fix the vertical rods 5 into the inserts 82 inside the upper cross beam 3. Finally, fix the upper cross beam 3, the lower cross beam 4 to the first upright column 1 and the second upright column 2. After installation, the upper cross beam 3 and the lower cross beam 4 are parallel to the slope body, and the first upright column 1, the second upright column 2 and the vertical rods 5 are all vertical and form a certain angle with the slope body. In actual installation, a number of this embodiment need to be spliced. The existence of the turning part 9 enables multiple this embodiments to be smoothly installed on the slope body.

[0066] After the installation of this embodiment is completed, it can intercept medium and large animals, and the size of the first gap 12 between two adjacent vertical rods 5 is relatively large, with good air permeability and small wind resistance. The baffle 6 located at the lower section of the vertical rod 5 can intercept small animals, and there is also a second gap 13 between adjacent baffles 6, which also has a certain air permeability, avoiding the problem of damage to the guardrail caused by too large wind resistance.

[0067] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or equivalently replace some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
