Description

Technical Field

[0001] The utility model belongs to the technical field of road protection, and in particular relates to a roadside rockfall protection structure. Background Art

[0002] When a highway passes through a hilly area, rocks falling from cliffs and steep slopes can easily pose a great threat to traffic facilities and personal safety below the slope, so it is necessary to protect the roadside from falling rocks.

[0003] A Chinese patent with publication number CN219992259U discloses a rock slope anti-rockfall grid, which includes a base and an interception component. A column is provided on the top of the base, and fixing grooves are provided on the two side walls of the column. The interception component is arranged between two adjacent columns. The above scheme utilizes the two ends of the interception component to be slidably connected in the fixing grooves of the adjacent columns, and the grid is quickly assembled. While protecting against falling rocks, it is also convenient to replace the damaged interception component.

[0004] During use of the above solution, when protecting heavy falling rocks, the interception components will be subjected to a large impact from the falling rocks and may be easily damaged, which will result in a shorter service life and poorer protection effect of the above solution. Utility Model Content

[0005] The utility model aims to provide a roadside rockfall protection structure to solve the problems of short service life and poor protection effect existing in the above-mentioned solutions.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A roadside rockfall protection structure comprises a column and a baffle, the rear end of the column is fixedly provided with a mounting plate protruding from the left and right sides of the column, and the left and right side walls of the column are respectively recessed with a plurality of slide grooves at intervals, one end of the slide groove passes through the rear side wall of the mounting plate, and a buffer assembly is arranged in the slide groove, and the column is arranged with a plurality of buffer assemblies at intervals, and the buffer assembly comprises a cross bar and a tension spring, the cross bar is slidably inserted in the slide groove, a connecting plate is fixedly provided at the rear end of the cross bar, the tension spring is sleeved outside the cross bar and respectively connected to the mounting plate and the connecting plate, and a mounting block is fixedly provided on the side wall of the front end of the cross bar outside the slide groove, and a fixing groove is recessed on the side of the mounting block away from the slide groove, and the baffle is provided with a plurality of baffles, each baffle is respectively arranged between two adjacent columns, and the left and right ends of the baffle are respectively slidably clamped in the corresponding fixing groove.

[0008] The principle and effect of this technical solution:

[0009] A plurality of uprights are fixedly arranged at intervals on one side of the road close to the slope with the mounting blocks facing the side of the slope, and the left and right ends of the baffle are slidably engaged in the corresponding fixing grooves. When falling rocks roll toward the road, they will first contact the baffle. The impact of the falling rocks will drive the cross bar to move, and at the same time, the tension spring will be stretched to give it a certain elastic force. Then the elastic force reacts to the baffle to cushion the impact of the falling rocks.

[0010] Through the above arrangement, the elastic force of the tension spring is utilized to buffer the impact of falling rocks, thereby preventing the baffle from being damaged by the impact of falling rocks, thereby improving the protective effect and extending the service life of the utility model.

[0011] The utility model further comprises a telescopic rod, one end of which is rotatably connected to the rear side wall of the column, and the other end of which is rotatably connected to a fixing plate. The bottom of the column is rotatably connected to a base.

[0012] The principle and effect of this technical solution:

[0013] The base is fixed on the ground, the telescopic rod is rotated, the fixing plate is fixed on the ground at an appropriate position, and then the telescopic rod is extended to adjust the angle between the column and the ground and the slope.

[0014] Through the above arrangement, on the one hand, the device can be arranged on an inclined ground, and on the other hand, the inclination angle of the column can be adjusted according to the inclination of the slope.

[0015] In the utility model, the telescopic rod comprises a screw and a rod sleeve, the top of the fixed plate is rotatably connected with a movable block, one end of the rod sleeve is rotatably connected to the movable block, the other end of the rod sleeve is fitted on one end of the screw, and the other end of the screw is rotatably connected to the rear side wall of the column.

[0016] The principle and effect of this technical solution:

[0017] The rod sleeve is rotated along the axial direction of the rod sleeve. Since the column restricts the screw rod from rotating along the axial direction of the rod sleeve, the screw rod moves relative to the rod sleeve as the rod sleeve rotates.

[0018] Through the above arrangement, the length of the screw rod extending out of the rod sleeve is changed by rotating the rod sleeve, so as to achieve the purpose of adjusting the length of the telescopic rod.

[0019] In the utility model, the front wall of the fixing groove is provided with a screw hole which passes through from front to back, and a fastening bolt is inserted into the screw hole.

[0020] The principle and effect of this technical solution:

[0021] After the baffle is slidably clamped in the fixing groove, it falls to the ground under the action of gravity, and the fastening bolts are matched and penetrated into the screw holes, and one end of the fastening bolts is extended into the fixing groove to press against the side wall of the baffle.

[0022] Through the above arrangement, it is possible to prevent the baffle from moving upward relative to the column after being impacted by falling rocks, thereby preventing the falling rocks from passing under the baffle, thereby further improving the protective effect of the utility model.

[0023] In the utility model, the side wall of the mounting block is slidably abutted against the side wall of the column. Through the above arrangement, the mounting block can be prevented from rotating relative to the column before the baffle is installed, which facilitates the staff to clamp the baffle into the fixing groove and improves work efficiency.

[0024] In the utility model, a first drill rod is slidably penetrated through the top of the fixing plate.

[0025] In the utility model, a second drill rod is slidably penetrated through the top of the base.

[0026] The principle and effect of this technical solution:

[0027] After placing the fixing plate and the base on the ground, the first drill rod is slidably inserted through the top of the fixing plate, and the second drill rod is slidably inserted through the top of the base, so that the bottoms of the first drill rod and the second drill rod are inserted into the ground.

[0028] Through the above arrangement, the purpose of fixing the fixing plate and the base on the ground is achieved, the column is prevented from tipping over, and the stability of the utility model is improved. BRIEF DESCRIPTION OF THE DRAWINGS
