Description

Technical Field

[0001] This utility model relates to the field of anti-collision pier technology, and in particular to an anti-collision pier for highway construction. Background Technology

[0002] When constructing or maintaining a highway, it is necessary to place some crash barriers around the construction site. On the one hand, this prevents vehicles from accidentally entering the construction site, and on the other hand, it isolates pedestrians and vehicles, facilitating the normal progress of highway construction.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0004] Existing technology, patent number CN221398781 U, discloses a crash barrier for highway construction, including a base plate. A rotating shaft is rotatably connected to the top front side of the base plate, and a buffer plate is rotatably connected to the base plate via the rotating shaft. Several support rods are fixedly connected to the rear side of the buffer plate. Several slots are formed on the base plate, and the support rods pass through the slots to directly support the ground. The advantage of this invention is that by setting support rods with compression springs on the rear side of the buffer plate, the support rods can directly support the ground. When the buffer plate is impacted, due to the high chassis of the vehicle, the top of the buffer plate is generally subjected to the impact force. The buffer plate tilts backward under the impact force, increasing the pressure of the support rods on the ground. This increases the suction effect of the suction cups on the ground and the friction between the support rods and the ground. By utilizing part of the impact force from the vehicle, the friction between the support rods and the ground is increased, thereby improving the stability of the crash barrier when impacted.

[0005] However, existing patents have the following drawbacks:

[0006] (1) This utility model of highway construction anti-collision pier does not have a component that allows the anti-collision pier to be moved quickly. Because the anti-collision pier is heavy, workers need to use professional tools to move it, which is time-consuming and laborious.

[0007] (2) This type of highway construction anti-collision pier lacks a deflection component. When the impacting object hits the anti-collision pier from the front, the anti-collision pier cannot deflect the impact in the opposite direction. The impact force on the front is relatively large, so both the anti-collision pier and the impacting object are subjected to a large impact and are easily damaged. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a highway construction anti-collision pier that can be stored, folded and supported for easy movement, and can deflect part of the impact force to reduce the head-on collision between the anti-collision pier and the impacting object.

[0009] To solve the above problems, the technical solution of this utility model is: a highway construction anti-collision pier, comprising:

[0010] The crash barrier body has a storage compartment on the inner bottom side, a limiting groove on both sides of the storage compartment, a rotating groove on both sides of the top, a disc groove on the top, and a positioning groove on one side of the disc groove.

[0011] A buffer deflection assembly is disposed on both sides of the crash barrier body. The buffer deflection assembly includes: a limiting shaft, a buffer plate, a spring, a support frame, and rollers. Several buffer grooves are opened on both sides of the crash barrier body. The limiting shaft is fixedly connected to the inner side of the buffer groove. The buffer plate is slidably connected to the inner side of the buffer groove. The buffer plate is slidably connected to the limiting shaft. The spring is sleeved on the outer side of the limiting shaft and fixedly connected between the buffer plate and the buffer groove. The support frame is fixedly connected to one side of the buffer plate. The rollers are rotatably connected between the support frames.

[0012] A drive assembly is disposed on the top of the crash barrier body;

[0013] A folding and moving component is disposed inside the storage compartment.

[0014] Furthermore, the drive assembly includes: a rotating disk, a rotating shaft, a sleeve, a connecting shaft, and a bevel gear. The rotating disk is rotatably connected to the inner side of the disk groove, the rotating shaft is rotatably connected to one side of the rotating disk, the sleeve is rotatably connected to the outer side of the rotating shaft, the connecting shaft is fixedly connected to the bottom end of the rotating disk and rotatably connected to the anti-collision block body, and the bevel gear is fixedly connected to the bottom end of the connecting shaft.

[0015] Furthermore, the folding and moving assembly includes: a forward and reverse lead screw, a second bevel gear, a limiting rod, a connecting frame, a lifting plate, casters, and a support rod. The forward and reverse lead screw is rotatably connected to the inner side of the rotating groove. The second bevel gear is fixedly connected to the outer side of the forward and reverse lead screw and meshes with the first bevel gear. The limiting rod is fixedly connected to the inner side of the storage compartment. The connecting frame is threadedly connected to the outer side of the forward and reverse lead screw and is slidably connected to the storage compartment and the limiting rod. The lifting plate is slidably connected to the inner side of the limiting groove. The casters are fixedly installed at the bottom end of the lifting plate. The support rod is rotatably connected between the connecting frame and the lifting plate.

[0016] The advantages of this invention compared to existing technologies are as follows:

[0017] (1) The present invention provides a folding and moving component for a highway construction anti-collision pier. The folding and moving component can be adjusted by the drive component so that the casters lift the anti-collision pier and the anti-collision pier can be moved quickly. The operation is simple, fast and labor-saving.

[0018] (2) The present invention provides a highway construction anti-collision pier equipped with a deflection component, which can deflect part of the impact force when subjected to a frontal impact, reduce the frontal collision between the anti-collision pier and the impacting object, protect the anti-collision pier and the impacting object, and reduce damage.

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Example 1:

[0028] like Figures 1 to 5 As shown,

[0029] A highway construction crash barrier includes: a crash barrier body 1, a storage compartment 2 is provided on the inner side of the bottom of the crash barrier body 1, limiting grooves 3 are provided on the bottom of both sides of the storage compartment 2, rotating grooves 4 are provided on the top of both sides of the storage compartment 2, a disc groove 5 is provided on the top of the crash barrier body 1, and a positioning groove 6 is provided on one side of the disc groove 5; a buffer deflection component 7 is provided on both sides of the crash barrier body 1; a drive component 8 is provided on the top of the crash barrier body 1; and a folding and moving component 9 is provided inside the storage compartment 2.

[0030] The drive assembly 8 includes: a rotating disk 801, a rotating shaft 802, a sleeve 803, a connecting shaft 804, and a bevel gear 805. The rotating disk 801 is rotatably connected to the inner side of the disk groove 5, the rotating shaft 802 is rotatably connected to one side of the rotating disk 801, the sleeve 803 is rotatably connected to the outer side of the rotating shaft 802, the connecting shaft 804 is fixedly connected to the bottom end of the rotating disk 801 and rotatably connected to the anti-collision block body 1, and the bevel gear 805 is fixedly connected to the bottom end of the connecting shaft 804.

[0031] Hold the sleeve 803 and rotate the rotating shaft 802 to remove it from the positioning groove 6, so that the rotating shaft 802 is perpendicular to the rotating disk 801. At this time, the rotating disk 801 can rotate. Hold the sleeve 803 and rotate the rotating disk 801, so that the connecting shaft 804 drives the bevel gear 805 to start rotating.

[0032] The folding and moving assembly 9 includes: a forward and reverse lead screw 901, a second bevel gear 902, a limiting rod 903, a connecting frame 904, a lifting plate 905, a caster wheel 906, and a support rod 907. The forward and reverse lead screw 901 is rotatably connected to the inner side of the rotating groove 4. The second bevel gear 902 is fixedly connected to the outer side of the forward and reverse lead screw 901 and meshes with the first bevel gear 805. The limiting rod 903 is fixedly connected to the inner side of the storage compartment 2. The connecting frame 904 is threadedly connected to the outer side of the forward and reverse lead screw 901 and is slidably connected to the storage compartment 2 and the limiting rod 903. The lifting plate 905 is slidably connected to the inner side of the limiting groove 4. The caster wheel 906 is fixedly installed at the bottom end of the lifting plate 905. The support rod 907 is rotatably connected between the connecting frame 904 and the lifting plate 905.

[0033] The rotating bevel gear 805 drives the bevel gear 902 to rotate, which in turn drives the forward and reverse lead screws 901 to rotate. Since the threads at both ends of the forward and reverse lead screws 901 are in opposite directions, they drive the connecting frame 904 to move away from each other, causing the support rod 907 to rotate and push the lifting plate 905 down, so that the caster wheel 906 touches the ground and continuously lifts the crash barrier body 1. After the crash barrier body 1 is lifted, the rotating shaft 802 is rotated so that the sleeve 803 is engaged in the positioning groove 6, locking the rotating disk 801. At this time, the folding moving component 9 is locked, and the worker can quickly move the crash barrier body 1.

[0034] The buffer deflection assembly 7 includes: a limiting shaft 701, a buffer plate 703, a spring 704, a support frame 705, and a roller 706. Several buffer grooves 702 are provided on both sides of the anti-collision block body 1. The limiting shaft 701 is fixedly connected to the inner side of the buffer groove 702. The buffer plate 703 is slidably connected to the inner side of the buffer groove 702. The buffer plate 703 is slidably connected to the limiting shaft 701. The spring 704 is sleeved on the outer side of the limiting shaft 701 and fixedly connected between the buffer plate 703 and the buffer groove 702. The support frame 705 is fixedly connected to one side of the buffer plate 703. The roller 706 is rotatably connected between the support frames 705.

[0035] When the crash barrier body 1 is hit head-on, the buffer plate 703 slides and compresses the spring 704 in the buffer groove 702, and the spring 704 completes a certain impact buffering. At the same time, the impacting object collides with the roller 706, causing the roller 706 to rotate. The impacting object is affected by the roller 706 and deflects at one end, which also deflects the subsequent impact, reducing the head-on impact on the crash barrier body 1.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
