Description

Technical Field

[0001] This utility model relates to the field of anti-collision column straightening, specifically to an anti-collision column straightening device. Background Technology

[0002] Crash bollards (also known as warning bollards) are usually placed on both sides of the road or in areas that need to be marked, and play an important role in guiding drivers to obey traffic rules and ensuring road safety.

[0003] However, in actual use, existing straightening methods have significant shortcomings when vehicle collisions cause pillars to bend. Currently, the common practice is for multiple people to work together, using force-applying sleeves to manually straighten the bent pillars. This method is not only time-consuming and labor-intensive, but also poses safety hazards. Especially when straightening operations are carried out in busy traffic areas, it disrupts normal traffic flow and may threaten the safety of the workers. In addition, traditional straightening methods make it difficult to precisely control the straightening force and angle, easily causing secondary damage or unsatisfactory straightening results. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a device for straightening anti-collision columns.

[0005] This utility model is achieved through the following technical solution:

[0006] This application provides a device for straightening a crash barrier post, including a sleeve that can be fitted onto the upper part of the crash barrier post, a support cantilever that is fixed to the side of the sleeve, a jack that can adjust the span at the lower part of the support cantilever, and a height adjustment component at the lower part of the jack.

[0007] Furthermore, this application also proposes that the lower part of the support cantilever is provided with a connecting groove, and the connecting groove has several adjustment holes, which are hinged to the top of the jack rod through pins.

[0008] Furthermore, this application also proposes that the height adjustment component includes a base plate, with two support plates on the upper part of the base plate, and several insertion holes on the two support plates, into which insertion rods hinged to the lower part of the jack are inserted.

[0009] Furthermore, this application also proposes that the upper part of the support cantilever is provided with a rib support that is reinforcedly connected to the sleeve.

[0010] Furthermore, this application also proposes that a support stop be provided at the top of the sleeve.

[0011] Compared with existing technologies, the advantages of this utility model are: by using the sleeve, support cantilever, jack and height adjustment component together, this utility model can enable a single person to complete the column straightening operation, avoiding the safety hazards of multiple people working together. At the same time, through the precise adjustment function of the jack and height adjustment component, the straightening force and angle can be accurately controlled. It has the advantages of simple operation, safety and reliability and precise control of straightening force and angle. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0016] like Figure 1-2 As shown, this application proposes a bollard straightening device, including a sleeve that can be fitted onto the upper part of the bollard, a support cantilever that is fixed to the side of the sleeve, a jack that can adjust the span at the lower part of the support cantilever, and a height adjustment component at the lower part of the jack.

[0017] The sleeve is a short tube, 10-20cm in length, with a hard rubber pad on the inner wall to increase friction with the column. The support cantilever and sleeve can be fixed by welding; the support cantilever can be made of square steel to enhance structural strength. A manual jack is preferred, with a bushing at the end of the jack rod for easy insertion and connection. The base plate in the height adjustment assembly can be made of steel, and the insertion holes on the support plate are evenly spaced. The insertion rod can be a cylindrical rod structure with a limiting pin.

[0018] This device achieves positioning by connecting a sleeve to the column, and uses the lifting force of the jack and the lever action of the support cantilever to straighten the column. The height adjustment component allows for rapid adjustment of the jack's working height through the cooperation of the insert rod with different holes, while the cooperation between the support cantilever and the jack allows for precise control of the straightening angle. Compared to traditional manual straightening methods, this device significantly reduces labor intensity, allowing for operation by a single person, and its mechanical structure ensures the stability and safety of the straightening process.

[0019] Furthermore, this application also proposes that the lower part of the support cantilever is provided with a connecting groove, and the connecting groove has several adjustment holes, which are hinged to the top of the jack rod through pins.

[0020] Specifically, the connecting groove can be an inverted U-shaped groove with a groove thickness of 8-12mm to ensure structural strength. Adjustment holes are evenly spaced along the length of the groove, with a spacing of 20-50mm and a diameter of 12-16mm to accommodate different specifications of pins. The pins are preferably made of 45# steel with a tempered finish, and their diameter is fitted with a transition fit to the adjustment holes. A bushing that rotates with the pin is installed at the end of the jack rod.

[0021] Therefore, through the coordinated design of the connecting groove and the adjustment hole, the installation position of the jack can be continuously adjusted, effectively adapting to the need for uprighting columns at different tilt angles. This structure utilizes a pin-hinged connection to transmit lifting force, ensuring efficient torque transmission while allowing the jack to swing freely within a certain angle range, preventing damage to the jack rod due to lateral forces caused by column tilting. Compared to the fixed connection structure in existing technologies, this solution significantly improves the device's adaptability to different working conditions, and the adjustment process requires no disassembly of parts, allowing for operation by a single person.

[0022] Furthermore, this application also proposes that the height adjustment component includes a base plate, with two support plates on the upper part of the base plate, and several insertion holes on the two support plates, into which insertion rods hinged to the lower part of the jack are inserted.

[0023] Specifically, the base plate, serving as the fundamental support component, can be made of steel plate or cast iron, with a thickness of 10-20mm to ensure structural strength. Support plates are vertically welded to the base plate, with spacing determined by the jack base dimensions, typically 100-200mm. Insertion holes are evenly spaced along the height of the support plate, with a hole diameter 1-2mm larger than the insertion rod diameter for easy insertion. The hole spacing is 20-50mm to allow for graded height adjustment. The insertion rod can be made of round steel, with through holes machined at both ends for pin connection to the jack base. The rod diameter is 20-30mm to ensure load-bearing capacity. As a preferred embodiment, the insertion holes can be elongated for fine-tuning the height, or positioning bolts can be added to the side of the support plate to enhance stability.

[0024] Therefore, this technical solution achieves rapid adjustment of the jack's support height through the cooperation of the insertion rod and multi-stage insertion holes. Compared with the existing technology that requires disassembly and reassembly of the support structure, this solution only requires pulling out the insertion rod and changing the insertion position to complete the height adjustment, reducing operation time by more than 70%. Simultaneously, the hinged structure allows the jack to adaptively tilt within a certain angle range, better adapting to the stress state of the column during straightening operations and avoiding stress concentration problems caused by rigid connections. The combined design of the base plate and double support plates gives the overall structure higher anti-overturning stability, capable of withstanding a maximum lateral load of 20kN.

[0025] Furthermore, this application also proposes that the upper part of the support cantilever is provided with a rib support that is reinforcedly connected to the sleeve.

[0026] Rib supports can be constructed by welding multiple short rods together in a triangular pattern between the sleeve and the support cantilever. By using rib supports, stress concentration at the connection point between the sleeve and the support cantilever can be effectively distributed. When the jack applies a straightening force, the rib supports prevent deformation or cracking at the connection between the support cantilever and the sleeve, thereby improving the overall structural stability. Compared to solutions without reinforcement, this design allows the straightening device to withstand greater bending moments, making it particularly suitable for straightening anti-collision columns with larger diameters or severe deformation.

[0027] Furthermore, this application also proposes that a support bar be provided at the top of the sleeve.

[0028] The support bar can be configured as a laterally extending rod-like structure, with both ends fixed to the top sides of the sleeve by welding. As a preferred embodiment, the support bar can be made of a circular steel tube.

[0029] This technical solution, by installing a support bar at the top of the casing, ensures that the casing is at the very top of the anti-collision column, thereby increasing the maximum torque on the bottom of the column and preventing the casing from falling off. This allows a single person to complete the straightening operation, solving the problem of existing technologies requiring multiple people and being laborious to operate. Compared to relying solely on the casing itself to bear the force, the support bar structure disperses stress concentration and improves the stability of the operation process.

[0030] The implementation principle of the anti-collision column straightening device in this application embodiment is as follows:

[0031] First, put the sleeve 1 on the top of the bent anti-collision column 11, and connect the top of the jack 10 to the adjustment hole 6 on the lower outer side of the support cantilever 3 through the pin. After connection, manually press the handle of the jack 10 to move the upper push rod of the jack 10 upward. The support cantilever 3 forms a lever to lift the anti-collision column 11 back to its original position. When the height of the jack 10 is not high enough, the position of the jack 10 on the support plate 7 of the height adjustment component can be adjusted to ensure adaptability to anti-collision columns 11 with different bending heights.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
