Description

Technical Field

[0001] The utility model belongs to the field of bridge construction equipment, in particular to a concrete bridge guardrail construction device. Background Art

[0002] Concrete bridge guardrails are indispensable protective structures on both sides of the beam surface. After the concrete is poured on the guardrails, the outside of the bridge guardrails needs to be repaired, demolded, and decorated. The construction involves high-altitude operations and has high safety risks. At present, after the workers complete the construction within a certain range, they must first return to the beam surface and then flip out the guardrail from another position to work. This consumes a lot of physical energy for the workers and poses great safety hazards during the operation. When constructing the outside of the bridge guardrail, the workers wear safety belts and use the work rope to work on the outside. When the wind is strong on site, the workers will swing left and right due to the influence of the wind and cannot work stably. If a car crane is used to suspend the cage for operation, two people are required to pull the wind rope for stability. In addition, the moving work is cumbersome when changing the construction position, and the manpower and material resources are consumed a lot, and the construction efficiency is low.

[0037] See attached Figures 1 to 4 , a schematic embodiment of the concrete bridge guardrail construction device proposed by the utility model is given, and the concrete bridge guardrail construction device is composed of a hanging basket 1 and a positioning assembly 2, wherein the positioning assembly 2 includes a first vertical rod 21, a first horizontal rod 22, a second horizontal rod 23 and a second vertical rod 24.

[0038] The hanging basket 1 is a cubic frame formed by connecting twelve frame rods 11. In this embodiment, the frame rods 11 are selected as angle steel keels, and the size of the angle steel keels is 5cm×5cm×5mm. The angle steel keels have the advantages of light weight, high rigidity, fire resistance, insect resistance, no deformation, firmness and not easy to crack. The size of the hanging basket 1 is 1.5m×0.75m×0.65m, and the maximum allowable load of the hanging basket 1 is 300kg. The operator stands on the hanging basket 1 to perform construction on the outside of the concrete bridge guardrail, which has high safety and stability.

[0039] The hanging basket 1 is fixed at the construction position outside the concrete bridge guardrail by the positioning assembly 2. In the positioning assembly 2, the first vertical rod 21 has a first end and a second end, and the first end of the first vertical rod 21 is connected to the hanging basket 1. The first horizontal rod 22 has a first end and a second end, and the first end of the first horizontal rod 22 is connected to the second end of the first vertical rod 21, and the first horizontal rod 22 is perpendicular to the first vertical rod 21. The second horizontal rod 23 has a hollow cavity, and the second end of the first horizontal rod 22 is inserted into the hollow cavity of the second horizontal rod 23, and the second horizontal rod 23 is slidably connected to the first horizontal rod 22. The second vertical rod 24 is vertically connected to the second horizontal rod 23. The first vertical rod 21, the first horizontal rod 22, the second horizontal rod 23 and the second vertical rod 24 form a positioning assembly 2 of a U-shaped structure, which is clamped on the concrete bridge guardrail, and the positioning assembly 2 can slide along the concrete bridge guardrail, so as to adjust the position of the concrete bridge guardrail construction device according to the operation point. In this embodiment, the first vertical rod 21 and the first horizontal rod 22 are square steel tubes with a size of 5 cm×5 cm×5 mm, and the second vertical rod 24 and the second horizontal rod 23 are square steel tubes with a size of 6 cm×6 cm×6 mm. The first vertical rod 21, the first horizontal rod 22 and the second horizontal rod 23 are 1 meter long, and the second vertical rod 24 is 0.5 meter long.

[0040] In order to prevent the positioning component 2 from damaging the concrete bridge guardrail when sliding along the concrete bridge guardrail, the concrete bridge guardrail construction device also includes a moving wheel 4, and a plurality of moving wheels 4 are provided. The plurality of moving wheels 4 are arranged on the contact surface between the positioning component 2 and the concrete bridge guardrail, thereby reducing the friction between the positioning component 2 and the concrete bridge guardrail, facilitating movement, and preventing damage to the guardrail. In this embodiment, see the attached Figure 1 Taking practical applications into consideration, four moving wheels 4 are provided on a positioning assembly 2, wherein one moving wheel 4 is provided on the second vertical rod 24, one moving wheel 4 is provided on the second horizontal rod 23, and the other two moving wheels 4 are provided on the first vertical rod 21.

[0041] When the positioning assembly 2 is clamped on the concrete bridge guardrail, the concrete bridge guardrail is located between the first vertical rod 21 and the second vertical rod 24. The first horizontal rod 22 is slidably connected to the second horizontal rod 23 to adjust the distance between the first vertical rod 21 and the second vertical rod 24, so that the concrete bridge guardrail construction device of this embodiment can be applied to bridge guardrails of various widths and sizes. One concrete bridge guardrail construction device can be reused and applied to different bridge guardrail constructions, with high flexibility, low construction cost, energy saving and environmental protection.

[0042] In order to ensure accurate positioning when the first horizontal rod 22 and the second horizontal rod 23 slide relative to each other to adjust the distance, and to improve the working efficiency of adjusting the distance, a plurality of first positioning holes 221 are provided on the first horizontal rod 22, and a plurality of second positioning holes 231 are provided on the second horizontal rod 23, and the plurality of first positioning holes 221 and the second positioning holes 231 correspond one to one. In this embodiment, the plurality of first positioning holes 221 are provided on two sides of the first horizontal rod 22, and the plurality of second positioning holes 231 are provided on two sides of the second horizontal rod 23, and the first positioning holes 221 and the second positioning holes 231 are holes with a diameter of 1 cm.

[0043] In order to maintain stability after the first horizontal rod 22 and the second horizontal rod 23 slide relative to each other to the set distance required for construction, the concrete bridge guardrail construction device also includes a positioning pin, which is inserted into the first positioning hole 221 and the second positioning hole 231 to lock the first horizontal rod 22 and the second horizontal rod 23. Ensure that during the construction process, the first horizontal rod 22 and the second horizontal rod 23 no longer slide relative to each other, ensuring construction safety. In some embodiments, the positioning pin can be replaced with a matching bolt and nut.

[0044] When the first horizontal rod 22 and the second horizontal rod 23 slide relative to each other to adjust the distance, in order to ensure that the two will not fall off and separate when sliding to the limit distance, the concrete bridge guardrail construction device also includes a limit assembly 3, and the limit assembly 3 includes a first limit member 31 and a second limit member 32.

The second limit member 32 is arranged at the opening of the hollow cavity of the second horizontal rod 23. When the first horizontal rod 22 and the second horizontal rod 23 slide relative to each other to the set position, the first limit member 31 abuts against the second limit member 32. The abutting first limit member 31 and the second limit member 32 limit the first horizontal rod 22 and the second horizontal rod 23 from continuing to slide after sliding relative to each other to the limit distance, thereby ensuring the overall stability of the device.

[0045] In order to ensure that the concrete bridge guardrail construction device can be conveniently and stably moved along the concrete bridge guardrail, in this embodiment, two groups of positioning components 2 are provided, and the two groups of positioning components 2 are fixed on the same side of the hanging basket 1. After the workers complete the construction of a certain work point, the workers on the bridge push the device to move the entire device to the next work point.

[0046] In order to make the workers stand stably when performing construction work in the hanging basket 1, a plurality of support rods 12 are provided on the bottom surface of the hanging basket 1, and the plurality of support rods 12 are fixedly connected to the hanging basket 1 in a grid shape. The provision of the support rods 12 enhances the stability of the hanging basket 1, and the workers stand on the support rods 12 to perform construction work, further ensuring the personal safety of the workers.

[0047] When carrying out construction work, workers will carry items for construction. In order to prevent the items for construction from falling, in this embodiment, a bottom plate 13 is provided on the plurality of support rods 12, and the bottom plate 13 can catch the construction items that accidentally fall. In some embodiments, the bottom plate 13 is a wooden template, and the wooden template is laid on the plurality of support rods 12. In some embodiments, the bottom plate 13 can also be a steel plate, and the steel plate is welded on the plurality of support rods 12.

[0048] In order to further improve the stability of the hanging basket 1 , four reinforcement rods 14 are respectively provided on the four sides of the hanging basket 1 , and the four reinforcement rods 14 are fixed to the hanging basket 1 in a crisscross shape.

[0049] In the above-mentioned schematic embodiment, the concrete bridge guardrail construction device consists of a hanging basket and a positioning assembly, which has a simple structure and is sturdy and durable. The positioning assembly can move along the bridge guardrail. After the construction of the outer side of the entire concrete bridge guardrail is completed, the device is lifted down as a whole using lifting equipment without the need for repeated lifting, thereby saving the cost of using machinery and equipment and improving construction efficiency.

[0050] The following is combined with Figures 1 to 4 The working process of an embodiment of the concrete bridge guardrail construction device of the utility model is described as follows:

[0051] First, determine the width of the concrete bridge guardrail, remove the positioning pins inserted in the first positioning hole 221 and the second positioning hole 231, slide the first horizontal rod 22 and the second horizontal rod 23 relative to each other, adjust the distance between the first vertical rod 21 and the second vertical rod 24 to be slightly larger than the width of the concrete bridge guardrail, and then insert the positioning pins in the first positioning hole 221 and the second positioning hole 231 to lock the first horizontal rod 22 and the second horizontal rod 23. During the adjustment process, the first limit member 31 and the second limit member 32 ensure that the first horizontal rod 22 and the second horizontal rod 23 do not separate and fall off.

[0052] Then determine the operating point of the concrete bridge guardrail, use lifting equipment to lift the entire device to the operating point, clamp the positioning assembly 2 on the concrete bridge guardrail, remove the positioning pin again, slide the first horizontal rod 22 and the second horizontal rod 23 relative to each other, adjust the distance between the first vertical rod 21 and the second vertical rod 24 to the appropriate width, and insert the positioning pin.

[0053] The workers enter the hanging basket 1 and carry out construction at the work point. After the construction is completed, the workers on the bridge push the device, and the positioning component 2 slides along the concrete bridge guardrail through the moving wheels 4 to move the entire device to the next work point.

[0054] After the construction of the outer side of the concrete bridge guardrail along the entire line is completed, the entire device will be lowered using lifting equipment.
