Description

A type of road construction bollard Technical Field

[0001] This utility model relates to the field of isolation post technology, and in particular to an isolation post for road engineering. Background Technology

[0002] Road safety barriers, as an important component of traffic management facilities, are primarily used to delineate different functional zones on roads, such as driving lanes, sidewalks, non-motorized vehicle lanes, and temporary construction areas, to ensure orderly traffic and reduce traffic accidents. These barriers are typically made of sturdy and durable materials, such as metal or rigid plastic, and possess a certain degree of impact resistance and stability. Their design aims to guide vehicles and pedestrians along designated routes through physical separation, thereby improving the safety and efficiency of road use.

[0003] To improve the safety of traffic bollards and reduce direct impact damage to vehicles, many traffic bollards on the market currently have rubber sleeves on their outer surfaces. However, these rubber sleeves are constantly exposed to the elements, and over time, oxidation and other factors cause them to age. When the rubber sleeves need replacement, the process is relatively cumbersome and time-consuming because they are usually glued to the bollard surface. This not only increases maintenance costs but also risks damaging the bollard surface due to improper handling. Therefore, a new type of traffic bollard for road engineering is needed to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a road engineering isolation post to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a road engineering bollard, including a locking base. An assembly column is fixedly connected to the top surface of the locking base, and an upright is fixedly connected to the top surface of the assembly column. The upright coincides with the axis of the assembly column. A sleeve is slidably connected to the outer surface of the upright. An internal hexagon bolt is threaded to the top surface of the sleeve, and the threaded portion of the internal hexagon bolt is threaded to the top end of the upright. A rubber sleeve is fixedly connected to the outer surface of the sleeve, and the bottom surface of the sleeve is fixed... A gasket is fixedly connected to the assembly column. The gasket has the same diameter as the rubber sleeve. The bottom surface of the gasket is in contact with the top surface of the assembly column. The top surface of the gasket is fixedly connected to the rubber sleeve. A plurality of circumferentially arrayed locking bolts are rotatably connected to one side of the locking base. The threaded part of the locking bolts is located below the locking base. A threaded sleeve is threadedly connected to the outer surface of the locking base. A pressure plate is fixedly connected to the top surface of the threaded sleeve. The pressure plate is rotatably connected to the assembly column. The bottom surface of the pressure plate is in contact with the nut part of the locking bolts.

[0007] Preferably, in any of the above solutions, the outer surface of the upright is fixedly connected to two symmetrically arranged clamping plates, and the inner wall of the sleeve is provided with two symmetrically arranged clamping grooves, and the sleeve is slidably connected to the two clamping plates through the two clamping grooves.

[0008] Preferably, in any of the above solutions, the bottom surface of the pad is fixedly connected with several pins, and the top surface of the assembly column is provided with several pin holes, and the pins are slidably connected to the assembly column through the pin holes.

[0009] Preferably, in any of the above embodiments, a sealing ring is fixedly connected to the bottom surface of the pad, and a sealing groove is provided on the top surface of the assembly column, wherein the sealing ring is slidably connected to the assembly column through the sealing groove.

[0010] Preferably, in any of the above embodiments, the top surface of the pressure plate has a through hole, the pressure plate is slidably connected to the assembly column through the through hole, and the height of the threaded sleeve is equal to the thickness of the locking base.

[0011] Preferably, in any of the above embodiments, the top of the rubber sleeve has a groove, the nut of the internal hexagonal bolt is located inside the groove, the top surface of the upright has a threaded hole, and the screw of the internal hexagonal bolt is threadedly connected to the top of the upright through the threaded hole.

[0012] Preferably, in any of the above embodiments, a rubber plug is slidably connected to the inner wall of the groove, a cover plate is fixedly connected to the top surface of the rubber plug, the bottom surface of the rubber plug is in contact with the top surface of the internal hex bolt, and the bottom surface of the cover plate is in contact with the top surface of the rubber sleeve.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. When installing the isolation column, the locking base can be locked in the working position using locking bolts. Then, the threaded sleeve is put on the locking base and rotated. The thread drive can drive the pressure plate to move downwards until the bottom surface of the pressure plate is in contact with the nut of the locking bolt. The top of the locking bolt can be squeezed and covered. Then, the sleeve is put on the upright. At this time, the clamping plate will be located inside the clamping groove, which can prevent the sleeve from rotating on the outer surface of the upright.

The top of the locking bolt is covered by the pressure plate, which can prevent rainwater from contacting the hex bolt and the locking bolt, and can reduce the rust rate of the two bolts.

[0015] 2. When the rubber sleeve needs to be replaced, first pull the rubber plug out of the groove to expose the top of the hex bolt. Then, remove the hex bolt to release the lock between the sleeve and the pole. The sleeve can then be quickly removed from the pole, allowing for quick removal of the rubber sleeve for easy replacement. Attached Figure Description

[0024] As an optional technical solution of this utility model, two symmetrically arranged clamping plates 11 are fixedly connected to the outer surface of the upright 3, and two symmetrically arranged clamping grooves 12 are opened on the inner wall of the sleeve 4. The sleeve 4 is slidably connected to the two clamping plates 11 through the two clamping grooves 12, so that the sleeve 4 is sleeved on the upright 3. At this time, the clamping plates 11 will be located inside the clamping grooves 12, which can prevent the sleeve 4 from rotating on the outer surface of the upright 3.

[0025] As an optional technical solution of this utility model, the bottom surface of the pad 7 is fixedly connected with several pins 13, and the top surface of the assembly column 2 is provided with several pin holes 14. The pins 13 are slidably connected to the assembly column 2 through the pin holes 14. After the pins 13 are inserted into the pin holes 14, the connection stability between the pad 7 and the assembly column 2 can be improved.

[0026] As an optional technical solution of this utility model, a sealing ring 15 is fixedly connected to the bottom surface of the pad 7, and a sealing groove 16 is opened on the top surface of the assembly column 2. The sealing ring 15 is slidably connected to the assembly column 2 through the sealing groove 16. The sealing ring 15 will be inserted into the sealing groove 16, which can improve the sealing performance between the pad 7 and the assembly column 2.

[0027] As an optional technical solution of this utility model, the top surface of the pressure plate 10 is provided with a through hole 17, and the pressure plate 10 is slidably connected to the assembly column 2 through the through hole 17. The height of the threaded sleeve 9 is equal to the thickness of the locking base 1.

[0028] As an optional technical solution of this utility model, the top of the rubber sleeve 6 is provided with a groove 18, the nut of the internal hex bolt 5 is located inside the groove 18, the top surface of the upright 3 is provided with a threaded hole 19, and the screw of the internal hex bolt 5 is threadedly connected to the top of the upright 3 through the threaded hole 19. By disassembling the internal hex bolt 5, the locking between the sleeve 4 and the upright 3 can be released, and then the sleeve 4 can be quickly removed from the upright 3, which can realize the quick disassembly of the rubber sleeve 6, so as to facilitate the quick replacement of the rubber sleeve 6.

[0029] As an optional technical solution of this utility model, a rubber plug 20 is slidably connected to the inner wall of the groove 18, and a cover plate 21 is fixedly connected to the top surface of the rubber plug 20. The bottom surface of the rubber plug 20 is in contact with the top surface of the internal hex bolt 5, and the bottom surface of the cover plate 21 is in contact with the top surface of the rubber sleeve 6. When the rubber plug 20 is inserted into the inner wall of the groove 18, the bottom of the internal hex bolt 5 can be sealed. The top of the locking bolt 8 is shielded by a pressure plate 10, which can prevent rainwater from contacting the internal hex bolt 5 and the locking bolt 8, and can reduce the rust rate of the two bolts.

[0030] A type of road safety bollard works on the following principle:

[0031] 1) When it is necessary to install the isolation column, the locking base 1 can be locked in the use position using the locking bolt 8. Then, the threaded sleeve 9 is put on the locking base 1 and rotated. Through the threaded transmission, the pressure plate 10 can be driven to move downward until the bottom surface of the pressure plate 10 is in contact with the nut part of the locking bolt 8. Then the top of the locking bolt 8 can be squeezed and the top of the locking bolt 8 can be covered.

[0032] 2): Sleeve 4 is fitted onto the upright 3. At this time, the clamping plate 11 will be located inside the clamping groove 12, which can prevent the sleeve 4 from rotating on the outer surface of the upright 3. After the pin 13 is inserted into the pin hole 14, the sleeve 4 is locked onto the upright 3 by the hex bolt 5.

[0033] 3): Pull the rubber plug 20 out of the groove 18 to expose the top of the hex bolt 5. Then, remove the hex bolt 5 to release the lock between the sleeve 4 and the pole 3. Then, the sleeve 4 can be quickly removed from the pole 3.

[0034] In summary, for the road construction project's guardrails, when installation is required, locking bolts 8 can be used to lock the locking base 1 in the desired position. Then, threaded sleeve 9 is fitted onto the locking base 1 and rotated. Through threaded transmission, pressure plate 10 moves downwards until the bottom surface of pressure plate 10 is in contact with the nut of locking bolt 8. This compresses and covers the top of locking bolt 8. Next, sleeve 4 is fitted onto the upright 3. At this point, clamping plate 11 is located inside clamping groove 12, preventing sleeve 4 from rotating on the outer surface of upright 3. After pin 13 is inserted into pin hole 14, sleeve 4 is locked onto upright 3 using hexagonal socket bolts 5. At this point, sealing ring 15 is inserted into the sealing ring. The sealing groove 16 improves the sealing performance between the gasket 7 and the assembly column 2. Finally, the rubber plug 20 is inserted into the inner wall of the groove 18 to seal the bottom of the hexagon socket bolt 5. The top of the locking bolt 8 is shielded by the pressure plate 10 to prevent rainwater from contacting the hexagon socket bolt 5 and the locking bolt 8, thus reducing the rust rate of the two bolts. When the rubber sleeve 6 needs to be replaced, the rubber plug 20 is first pulled out from the groove 18 to expose the top of the hexagon socket bolt 5. Then, the hexagon socket bolt 5 is disassembled to release the lock between the sleeve 4 and the upright 3. The sleeve 4 can then be quickly removed from the upright 3, allowing for quick disassembly of the rubber sleeve 6 for easy replacement.
