Description

Technical Field

[0001] The utility model relates to the field of slope protection facilities, in particular to a passive slope protection net device. Background Art

[0002] High-speed railways, highways, hydropower stations and other related construction areas inevitably pass through mountainous areas or are located in high and steep slope environments. Due to the long-term exposure to wind and sun, the mountain body has weathered, unloaded and other geological changes on the surface, making the broken stones unstable, posing a serious threat to on-site construction and road safety. If the possible risk of falling rocks is not eliminated, active protection nets, passive protection, retaining walls, etc. are usually used to intercept them in dangerous areas.

[0003] In the existing technology, the passive protection net usually includes a base, a column, a rope net, and upper and lower support ropes, etc. However, the existing passive protection net still has the following shortcomings in actual use: First, the column is installed on the base through a simple hinge structure. The existing base and the column are stuck after installation and cannot be deflected, and cannot effectively buffer and dissipate energy. When the passive protection net is impacted by falling rocks, the column is easily bent and damaged, which leads to the failure of the entire passive protection net system. Second, the passive protection net is fixed on the column once and for all. When the net intercepts the falling rocks, there are problems such as difficulty in cleaning the fallen rocks and difficulty in replacing the net. It can only be replaced by dismantling and rearranging a new passive protection net device. Third, the height of the existing passive protection net is set according to different energy levels, and there are many types. Each energy level corresponds to a height. After installation, the height of the net and the column cannot be adjusted, and the adjustability is poor. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a slope passive protection net device which can adjust the height of the protection net so as to adapt to the protection energy level requirements.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a passive slope protection net device, including a pair of columns, the columns are arranged in the vertical direction, a rollable and retractable protection net is arranged between the columns, the protection net includes at least two protection net units, two adjacent protection net units are connected to each other by a locking buckle assembly, the left and right sides of the protection net can be slidably arranged in the slide groove of the column, and the left and right sides of the protection net are fixedly arranged at any position in the slide groove by a protection net locking device.

[0006] Furthermore, the locking buckle assembly includes a locking buckle hook and a locking buckle slot, the locking buckle hook and the locking buckle slot are respectively arranged on the sides of two adjacent protective net units, and the locking buckle hook is snap-connected in the locking buckle slot.

[0007] Furthermore, the protective net locking device includes a side hook of the protective net and a locking thread, the side hook is clamped in the buckle of the locking thread, the locking thread is arranged in the slide groove, the locking thread can slide along the slide groove direction of the column and can be tightened at any position in the slide groove.

[0008] Furthermore, it includes a protective net storage roller, in which a protective net unit is curled and stored; when the protective net unit between the columns slides upward, the protective net unit in the protective net storage roller is pulled out and arranged between the columns to form a protective net; when the protective net unit between the columns slides downward, the protective net between the columns is curled and stored in the protective net storage roller.

[0009] Furthermore, the column includes an outer column, a first inner column sleeved in the outer column, and a second inner column sleeved in the first inner column. The first inner column and the second inner column slide along the direction of the outer column. The side walls of the first inner column and the second inner column are provided with inner and outer column locking buckles. The first inner column and the second inner column are locked in position by the inner and outer column locking buckles.

[0010] Furthermore, a tension locking ring is provided on the top side wall of the second inner column; it includes a pull rope, the pull rope includes a rope body and a damping energy dissipation device arranged on the rope body, one end of the rope body is fixedly arranged on the tension locking ring, and the other end of the rope body is fixedly arranged on the mountain foundation.

[0011] Furthermore, an energy dissipation device and a base are provided at the bottom of the column, and the energy dissipation device includes a top plate of the energy dissipation device, a spring shock-absorbing energy dissipation device and a hydraulic buffer energy dissipation device. The top plate of the energy dissipation device is fixedly connected to the bottom of the column, the spring shock-absorbing energy dissipation device is arranged between the top plate of the energy dissipation device and the top plate of the base, one end of the hydraulic buffer energy dissipation device is fixedly arranged on the top plate of the energy dissipation device, and the other end of the hydraulic buffer energy dissipation device is arranged on the top plate of the base.

[0012] The beneficial effect of the utility model is that in actual use, the height of the protective net between the columns can be adjusted according to actual needs. When the height of the protective net needs to be increased, the protective net is slid upward along the slide groove of the column. Since the two protective net units are connected to each other through a locking buckle assembly, several protective net units can together form a complete protective net. When the height of the protective net needs to be lowered, the protective net is slid downward along the slide groove of the column. In addition, since the protective net is composed of independent protective net units connected to each other, even if a single protective net unit needs to be disassembled and replaced later, it can be very convenient. The utility model is particularly suitable for slope protection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 7The passive slope protection net device shown includes a pair of columns 2, the columns 2 are arranged in the vertical direction, and a rollable and retractable protection net 1 is arranged between the columns 2. The protection net 1 includes at least two protection net units 11, and two adjacent protection net units 11 are connected to each other by a locking buckle assembly. The left and right sides of the protection net 1 can be slidably arranged in the slide groove of the column 2, and the left and right sides of the protection net 1 are fixedly arranged at any position in the slide groove by the protection net locking device. Before the installation of the passive slope protection net device, each module is separated separately to facilitate transportation before installation. Its split design also provides convenience for on-site construction during maintenance and replacement. The damaged device can be replaced separately, which overcomes the trouble of overall replacement after damage in the prior art and saves a lot of manpower and material resources. In addition, after the small gravel is intercepted, it can be caught by removing the net, so as to achieve the purpose of cleaning up the fallen rocks at one time, overcoming the problem that the fallen rocks can only be cleaned up manually one by one at this stage.

[0023] After the rock falls down the hillside, it impacts the passive slope protection net device and is intercepted by the protection net unit 11. The protection net unit 11 is fixed to the column 2 through the side hook 12 and the locking thread 24. The passive slope protection net device mitigates the impact energy of the rock falls through the energy dissipation device 3 and the damping energy dissipation device 62. The energy dissipation device 3 mitigates the energy transmitted from the upper column 2 through the spring shock-absorbing energy dissipation device 32 and the hydraulic buffer energy dissipation device 33 to ensure the normal use of the device.

[0024] According to the rolling situation of falling rocks on the slope, the height is adjusted by adjusting the column 2. The specific method of adjusting the height is: the first inner column 22 and the second inner column 23 slide up and down along the outer column 21. After the first inner column 22 and the second inner column 23 are adjusted to the required height, the first inner column 22 and the second inner column 23 are fixed to the corresponding height through the inner and outer column locking buckles 26 and the locking threads 24. The height of the protective net unit 11 is adjusted through the side hooks 12 and the locking threads 24. The protective net unit 11 drives the protective net storage roller 5 to pull out the protective net unit 11 in the protective net storage roller 5, so that the entire height is covered with the protective net 1 to meet the on-site requirements.

[0025] The base 4 is fixed to the ground slope by locking anchor rods 42, the energy dissipation device 3 is fixed to the base 4 by spring shock-absorbing energy dissipation device 32 and hydraulic buffer energy dissipation device 33, the column 2 is fixed to the top plate 31 of the energy dissipation device, and the first inner column 22 and the second inner column 23 are fixed to the outer column 211 by the slide groove of the column 2 and the inner and outer column locking buckle 26. At the same time, the protective net unit 11 moves up and down in the slide groove of the column 2 through the locking thread 24 and the protective net unit 11, so that the protective net unit 11 can reach the required height. At the same time, the protective net units 11 are connected to form a continuous structure by the locking buckle hook 13 and the locking buckle bayonet 14, and the protective net storage roller 5 stores the protective net units 11 of corresponding length to meet the requirements of different protection heights. At the same time, the pull rope 6 fixes the column 2 at the corresponding position by anchoring on the mountains on both sides, and the pull rope 6 is provided with a damping energy dissipation device 62 to reduce the impact damage of falling rocks on the device.
