Description

Technical Field

[0001] The utility model relates to the technical field of road safety protection, in particular to a buffer column for municipal roads. Background Art

[0002] In municipal management, road safety protection is extremely important. Against the backdrop of the rapid development of automobiles, traffic accidents on roads often occur. To provide certain protection for automobiles, buffer columns are set on relevant roads to block and buffer the automobiles. However, the current traditional road columns have a simple structure and are usually made of steel; they are fixed to the ground on both sides of the intersection by expansion bolts; when being impacted, although the blocking ability is strong, the buffering effect on the impact object is poor, and the column itself is also prone to cause reverse damage to the automobile, resulting in poor use effects. Content of the Utility Model

[0003] The purpose of the utility model is to provide a buffer column for municipal roads to solve the above-mentioned deficiencies in the prior art.

[0004] The utility model provides the following technical solution: a buffer column for municipal roads, including a central column. Multiple sets of ring sleeves and the same number of ring cylinders are arranged outside the central column. The ring sleeves are rotatably installed outside the central column. The ring sleeves and the ring cylinders are connected by a plurality of elastic connectors. The elastic connectors can be spring structures. The two ends of the elastic connectors are respectively fixedly connected to the ring sleeves and the ring cylinders, and the plurality of elastic connectors are evenly distributed in a circumferential direction inside the ring cylinder. The elastic connectors are arranged along the radial direction of the ring cylinder. A sealing cover is detachably installed at the top of the central column. After the sealing cover is installed on the top of the central column, it seals each ring sleeve. Thus, in actual use, the multiple ring cylinders are naturally stacked into a whole cylindrical structure. When being impacted, it can follow the actual shape and impact area of the impact object, causing the corresponding ring cylinder to generate a lateral offset. At this time, the elastic buffer can be carried out by means of each elastic connector inside the corresponding ring cylinder. Moreover, since the elastic connectors are circumferentially distributed, the ring cylinder can withstand and buffer impacts from multiple directions. At the same time, since the ring cylinder at the specific contact position of the corresponding impact object only offsets after being contacted, the overall device can generate uniform buffer force unloading adapted to the external shape of the impact object. At the same time, since the ring sleeve can rotate relative to the central column, when the impact object impacts the device obliquely, the impact force can be decomposed and deflected by means of the rotation of the ring cylinder and the ring sleeve, causing the impact object to generate a certain offset and force unloading, thereby avoiding the problems of poor buffer effect and large damage to the impact object caused by the concentrated impact force and impact point, thus greatly improving the buffer effect of the device and enhancing the road safety effect of municipal management.

[0005] Preferably, a mounting plate is fixedly connected to the bottom of the central column. The mounting plate is installed on the ground through expansion bolts. A pre-buried part is fixedly connected to the bottom end of the central column, and the pre-buried part is buried below the ground, thereby improving the support and installation of the central column.

[0006] Preferably, a thread is provided at the top of the central column. The capping cover is threadedly sleeved outside the top end of the central column. A thin-walled metal cover is fixedly connected to the outside of the capping cover. The thin-walled metal cover covers the area where the annular cylinder is located, thereby facilitating the assembly of the device. At the same time, the top of the device can also be protected by the thin-walled metal cover. The thin-walled metal cover adopts a thin-walled structure and is prone to deformation when impacted, and will not cause reverse damage to the impact object.

[0007] Preferably, bearings are provided between the collar and the central column and between the collars. A radial bearing is provided between the collar and the central column, and an axial bearing is provided between the collars, thereby making it easier for the annular cylinder to rotate.

[0008] Preferably, a plurality of rubber cross columns are fixedly connected to the inner wall of the annular cylinder. The rubber cross columns are inserted into the elastic connectors, thereby supporting the elastic connectors. When the impact is too strong and the rubber cross columns contact the collar, further buffering can also be performed.

[0009] Preferably, inner edges are provided on the inner sides of the top and bottom of the annular cylinder, thereby increasing the contact area between the annular cylinders and improving the stability of the translation between two adjacent annular cylinders.

[0010] Preferably, a plastic outer shell is provided on the outside of the collar. The plastic outer shell covers the outside of a plurality of annular cylinders, thereby protecting the annular cylinders and preventing unauthorized personnel from manually pushing the annular cylinders and affecting the use. At the same time, reflective signs can also be pasted on the plastic outer shell. When impacted, the plastic outer shell can be broken, without affecting the operation of the annular cylinder.

[0011] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0012] By arranging multiple groups of annular cylinders outside the central column, and using the elastic connectors inside the annular cylinders for elastic buffering, the annular cylinder corresponding to the specific contact position of the impact object deflects only after being contacted. Therefore, the overall device can generate uniform buffer and force unloading adapted to the external shape of the impact object. When the impact object impacts the device obliquely, the impact force can be decomposed and deflected by means of the rotation of the annular cylinder and the collar, avoiding the problems of deviation in the buffer effect and large damage to the impact object caused by the concentrated impact force and impact point, thereby greatly improving the buffer effect of the device.

[0019] Embodiment

[0020] The present utility model provides as Figures 1-3A buffer column for a municipal road as shown includes a central column 1. Multiple sets of annular sleeves 2 and the same number of annular cylinders 3 are arranged outside the central column 1. The annular sleeves 2 are rotatably installed outside the central column 1. The annular sleeves 2 and the annular cylinders 3 are connected by a plurality of elastic connectors 4. The elastic connectors 4 can be selected as spring structures. The two ends of the elastic connectors 4 are respectively fixedly connected to the annular sleeves 2 and the annular cylinders 3. And the plurality of elastic connectors 4 are evenly distributed in a circumferential direction inside the annular cylinder 3. The elastic connectors 4 are arranged along the radial direction of the annular cylinder 3. A sealing cover 6 is detachably installed at the top of the central column 1. After the sealing cover 6 is installed on the top of the central column 1, it seals each annular sleeve 2. When the above device is set on the road under municipal management, in actual use, the plurality of annular cylinders 3 are naturally stacked into an entire cylindrical structure. When being impacted, it can follow the actual shape and impact area of the impact object, causing the annular cylinder 3 at the corresponding position to generate a lateral offset. At this time, the elastic buffer can be carried out by means of each elastic connector 4 inside the corresponding annular cylinder 3. And because the elastic connectors 4 are distributed in a circumferential direction, the annular cylinder 3 can withstand and buffer impacts from multiple directions. At the same time, because the annular cylinder 3 at the specific contact position of the corresponding impact object only offsets after being contacted, the overall device can generate uniform buffer force unloading adapted to the external shape of the impact object. At the same time, because the annular sleeve 2 can rotate relative to the central column 1, when the impact object impacts the device obliquely, the impact force can be decomposed and deflected by means of the rotation of the annular cylinder 3 and the annular sleeve 2, so that the impact object can generate a certain offset and force unloading, thereby avoiding the problems of poor buffer effect caused by concentrated impact force and impact point and large damage to the impact object, thus greatly improving the buffer effect of the device and enhancing the road safety effect of municipal management.

[0021] Further, in the above technical solution, a mounting plate 11 is fixedly connected to the bottom of the central column 1. The mounting plate 11 is installed on the ground through expansion bolts. A buried part 12 is fixedly connected to the bottom end of the central column 1. The buried part 12 is buried below the ground, thereby improving the support and installation of the central column 1.

[0022] Further, in the above technical solution, the top of the central column 1 is provided with threads. The sealing cover 6 is threadedly sleeved outside the top end of the central column 1. A thin-walled metal cover 61 is fixedly connected to the outside of the sealing cover 6. The thin-walled metal cover 61 covers the area where the annular cylinder 3 is located, thereby facilitating the assembly of the device. At the same time, the top of the device can also be protected by means of the thin-walled metal cover 61. The thin-walled metal cover 61 adopts a thin-walled structure and is easy to deform when being impacted, and will not cause reverse damage to the impact object.

[0023] Further, in the above technical solution, bearings 7 are arranged between the annular sleeve 2 and the central column 1 and between the annular sleeves 2. And a radial bearing is arranged between the annular sleeve 2 and the central column 1, and an axial bearing is arranged between the annular sleeves 2, thereby making it easier for the annular cylinder 3 to rotate.

[0024] Furthermore, in the above technical solution, a plurality of rubber cross-columns 5 are fixedly connected to the inner wall of the annular cylinder 3. The rubber cross-columns 5 are inserted into the elastic connecting member 4. Thus, while supporting the elastic connecting member 4, if the impact is too strong, the rubber cross-columns 5 will contact the collar 2, and further buffering can also be carried out.

[0025] Furthermore, in the above technical solution, inner edges 31 are provided on the inner sides of the top and bottom of the annular cylinder 3, which can increase the contact area between the annular cylinders 3, thereby improving the stability of the translation between two opposite annular cylinders 3.

[0026] Furthermore, in the above technical solution, a plastic outer shell 8 is provided outside the collar 2. The plastic outer shell 8 covers the outside of a plurality of annular cylinders 3, thereby protecting the annular cylinders 3 and preventing unauthorized personnel from manually pushing the annular cylinders 3 and affecting the use. At the same time, reflective markings can also be pasted on the outside of the plastic outer shell 8. When impacted, the plastic outer shell 8 can be broken, which does not affect the operation of the annular cylinders 3.

[0027] Working principle: By arranging multiple groups of annular cylinders 3 outside the central column 1 and using the collar 2 and the elastic connecting member 4 to support the annular cylinders 3. During actual use, a plurality of annular cylinders 3 are naturally stacked into a whole cylindrical structure. When impacted, it can follow the actual shape and impact area of the impact object, causing the annular cylinders 3 at the corresponding positions to generate lateral offsets. At this time, the elastic buffer can be carried out by means of the respective elastic connecting members 4 inside the corresponding annular cylinders 3. Moreover, since the elastic connecting members 4 are circumferentially distributed, the annular cylinders 3 can withstand and buffer impacts from multiple directions. At the same time, since the annular cylinders 3 at the specific contact positions of the corresponding impact object are offset only after being contacted, the overall device can generate uniform buffer force relief adapted to the external shape of the impact object. At the same time, since the collar 2 can rotate relative to the central column 1, when the impact object impacts the device obliquely, the impact force can be decomposed and deflected by means of the rotation of the annular cylinders 3 and the collar 2, so that the impact object can generate a certain amount of offset force relief, thereby avoiding problems such as poor buffer effect caused by concentrated impact force and impact point and large damage to the impact object, and greatly improving the buffer effect of the device and enhancing the road safety effect of municipal management.
