Description

Technical Field

[0001] The invention relates to the technical field of constructing temporary access roads, in particular to a quick-assembly access road device. Background Art

[0002] Sidewalks are a crucial component of urban municipal projects, particularly those involved in the renovation of older residential communities, pipeline network upgrades, and trench excavation, impacting the overall living experience of community residents during the construction process. Sidewalks, such as steel sidewalks and anti-slip sidewalks, are particularly common in residential design, renovation, and construction. In practice, these sidewalks often suffer from issues such as being too heavy to transport, being too small to fit the finished trench width, and making excessive noise from passing vehicles. However, as a crucial safety measure for municipal and community renovations, their effectiveness has been a source of complaints and reports from community residents and a major pain point in construction.

[0003] Especially in large-scale renovation projects of old communities, dozens of communities in the area are often renovated together. The treatment of trenches and sidewalks seriously affects the overall construction effect and progress.

[0004] The current solution is generally to transport steel plates to designated trench locations by machinery, but this method relies entirely on the technical level of the machine operator. In addition, steel plates are expensive and the noise pollution during construction is too great, which undoubtedly increases the construction cost of the project. In addition, the traffic efficiency is low, making it difficult to ensure construction safety and affecting the construction quality of pipeline renovation projects. Summary of the Invention

[0005] In order to reduce the conflict between urban reconstruction projects and the normal lives of citizens, improve the construction progress of reconstruction projects, and reduce the construction cost of temporary walkways, the present invention provides a quick-assembly walkway device.

[0006] The present invention provides a quick assembly walkway device that adopts the following technical solutions:

[0007] A quick-assembly walkway device includes a top plate support, a slope plate support and a support panel. The slope plate support is arranged on both sides of the top plate support to form an arch bridge structure. The support panel is laid on top of the top plate support and the slope plate support. The slope plate support and the top plate support are hinged to each other through a hinge shaft and fixedly connected at multiple angles through a diagonal support. The support panel is composed of multiple plates that are chain-hinged in sequence.

[0008] By adopting the above technical solution, the top plate support and the slope plate support are assembled with each other, which is easier to store and transport than a whole piece of steel plate. When connected into a bridge shape, its bearing capacity is greater than that of a flat plate structure and its service life is long. The support panel is used to support the passage of people and vehicles. The inclined support can adjust the installation angle of the top plate support and the slope plate support, which is suitable for the installation of temporary trenches with various widths and height requirements. The support panel is composed of multiple plates chain-hinged in sequence, which is conducive to the support panel being close to the top plate support and the slope plate support, thereby improving the stability and user experience.

[0009] Preferably, the top plate support is separated into two parts from the middle, and the two parts of the top plate support are respectively slidably connected to the telescopic frame.

[0010] By adopting the above technical solution, the telescopic frame is used to extend the length of the top plate support, meeting the requirements for setting up a walkway in a wider trench. It has a wide range of applications and is easy to adjust without the need for extra installation steps.

[0011] Preferably, a structural cross bar and a support cross bar are provided on the top plate support. The structural cross bar is fixed to the middle position of the inner side of the top plate support by welding. The support cross bar is detachably arranged in the notch at the top of the top plate support. The installation top surface of the support cross bar is higher than the top surface of the top plate support.

[0012] By adopting the above technical solution, the structural cross bar is conducive to improving the structural bearing strength of the top plate support and increasing the service life of the top plate support. The support cross bar is used to assist in supporting the panel support and reduce the chance of high impact damage to the support panel.

[0013] Preferably, the support panel includes a top plate and a slope plate, the slope plates are hinged on both sides of the top plate respectively, the top plate is laid on the top plate support, the slope plate is laid on the slope plate support, and a positioning groove is opened at the bottom of the support panel corresponding to the position of the support cross bar.

[0014] By adopting the above technical solution, the positioning groove and the supporting cross bar are installed in coordination with each other, thereby improving the anti-slip ability of the supporting panel on the top plate support and the slope plate support.

[0015] Preferably, the top plate is separated into two parts from the middle, and the two parts of the top plate are respectively slidably connected to the splicing plate.

[0016] By adopting the above technical solution, the splicing plate is used to extend the length of the top plate, effectively cooperating with the extension of the top plate support, and ensuring that the installation position of the slope plate remains unchanged.

[0017] Preferably, step-in boards are movably hinged at both ends of the support panel, and the end edges of the top surfaces of the step-in boards are in close contact with the ground.

[0018] By adopting the above technical solution, the step-in plate is close to the ground and effectively connected with the ground, reducing the bumpy feeling of the vehicle and the possibility of pedestrians tripping due to the bulge.

[0019] Preferably, the end of the ramp support that contacts the ground is provided with a ground anchor and a triangular prism, the ground anchor is inserted into a through hole on the side of the ramp support, and the triangular prism is laterally hinged to the bottom end of the ramp support.

[0020] By adopting the above technical solution, the ground anchors are used to fix the entire walkway, reducing the movement and deviation of the walkway caused by external interference, and the triangular frame is used to reduce the pressure of the walkway on the ground, slowing down the walkway from sinking into soft ground.

[0021] Preferably, the ramp supports are connected to each other via a pull chain, and the pull chain is connected at the middle or bottom of the ramp support.

[0022] By adopting the above technical solution, the pull chain is used for safety protection to prevent collapse accidents caused by unreasonable installation or structural damage.

[0023] Preferably, a pedal support is provided on the ramp support, one side of the pedal support is slidably provided on the inner side of the ramp support, and the other side of the pedal support is adjustably installed through a movable frame, and multiple pedal supports are evenly arranged along the side panels of the ramp support structure frame, and a pedal is provided on the support panel, one side of the pedal is hinged to a rectangular opening on the support panel, and the other side of the pedal is overlapped on the pedal support and adjustably installed through the pedal support.

[0024] By adopting the above technical solution, the pedal is used to facilitate pedestrians to pass when the ramp support and the ramp angle are large, and the pedal support is used to control the folding of the pedal and keep the angle horizontal, so as to meet the switching of the two required states of the ramp.

[0025] Preferably, the top plate support, slope plate support and support panel are arranged transversely and connected by expansion connecting rods, and the bottoms of adjacent slope plate supports are connected and fixed by connecting bolts.

[0026] By adopting the above technical solution, parallel expansion can increase the width of the sidewalk to facilitate improving traffic efficiency and allow wider vehicles to pass through.

[0027] In summary, the present invention has the following beneficial technical effects:

[0028] 1. The top plate support and the slope plate support are assembled with each other. Compared with the whole steel plate, they are easier to store and transport. When connected into a bridge shape, their bearing capacity is greater than that of the flat plate structure and their service life is long. The support panel is used to support the passage of people and vehicles. The inclined support can adjust the installation angle of the top plate support and the slope plate support, which is suitable for the installation of temporary trenches with various widths and heights.

[0029] 2. The telescopic frame is used to extend the length of the top plate support to meet the requirements for setting up walkways in wider trenches. It has a wide range of applications and is easy to adjust without the need for extra installation steps. The structural cross bar is beneficial to improving the structural bearing strength of the top plate support and increasing the service life of the top plate support. The support cross bar is used to assist in supporting the support panel and reduce the chance of high impact damage to the support panel. The positioning groove and the support cross bar are installed in coordination with each other to improve the anti-slip ability of the support panel on the top plate support and the slope plate support. The splicing plate is used to extend the length of the top plate, effectively cooperating with the extension of the top plate support to ensure that the installation position of the slope plate remains unchanged. The step-in plate is close to the ground and effectively connected to the ground, reducing the increased vehicle bumps and the possibility of pedestrians tripping due to the bulge.

[0030] 3. The anchors are used to fix the entire walkway and reduce the movement and deviation of the walkway caused by external interference. The triangular frame is used to reduce the pressure of the walkway on the ground and slow down the walkway from sinking into soft ground. The traction chain is used for safety protection to prevent collapse accidents caused by unreasonable installation or structural damage. The pedals are used to facilitate pedestrians to pass when the ramp support and the ramp angle are large. The pedal support is used to control the retraction of the pedal and keep the angle horizontal to meet the switching of the two required states of the ramp. Parallel expansion can increase the width of the walkway to facilitate the improvement of traffic efficiency and allow wider vehicles to pass. BRIEF DESCRIPTION OF THE DRAWINGS
