Description

Technical Field

[0001] This utility model relates to the technical field of highway slope protection railings, specifically a highway slope safety protection device. Background Technology

[0002] To prevent rocks and soil from falling off roadside slopes due to weathering and damage, or to avoid safety accidents caused by slope collapses during highway construction, slope protection railings are usually installed along the roadside to prevent rocks and soil from rolling onto the road surface.

[0003] Publication No. CN218813250U discloses a highway slope protection barrier. This device is easy to install, and the impact force generated by falling rocks hitting the protective net is transmitted to the compression spring through the edge band, which is used for buffering. Compared with the prior art, it improves the load-bearing capacity of the connection structure between the protective net and the post, effectively preventing the guardrail from being damaged or tilted, and increasing its service life. However, this patent still has the following problems in actual use:

[0004] This device transmits the impact force generated by falling rocks hitting the protective netting to a compression spring via a sealing hoop. The compression spring then acts as a buffer, improving the load-bearing capacity of the connection structure between the protective netting and the posts compared to existing technologies. This effectively prevents the guardrail from being damaged or tilted, and extends its service life. In existing technologies, guardrails are usually connected using bolts and nuts, which cannot achieve a quick connection and fixation between guardrails. This requires workers to operate wrenches and other tools to operate multiple sets of bolts, greatly reducing the efficiency of guardrail assembly and the efficiency of highway slope protection.

[0005] A highway slope safety protection device is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a highway slope safety protection device to solve the problem mentioned in the background technology, which uses the edge banding to transfer the impact force generated by falling rocks on the protective net to the compression spring for buffering. Compared with the prior art, this improves the bearing capacity of the connection structure between the protective net and the post, effectively preventing the guardrail from being damaged or tilted, and increasing its service life. In the prior art, the connection between guardrails is usually fixed with bolts and nuts, which cannot achieve the effect of quick connection and fixation between guardrails. Therefore, workers need to operate wrenches and other tools to operate multiple sets of bolts, which greatly reduces the assembly efficiency of guardrails.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a highway slope safety protection device, comprising an installation frame, a protective net fixedly installed inside the installation frame, and support columns symmetrically arranged on both sides of the installation frame, with a base fixedly installed at the bottom of the support columns; a fixing mechanism is provided between the installation frame and the support columns, and a limit component is provided on the reverse side of the support columns;

[0008] The fixing mechanism includes a limiting plate, which is symmetrically fixedly installed on both sides of the mounting frame. Limiting grooves are symmetrically opened on both sides of the support column. An end plate is provided on the top of the support column, and limiting blocks are symmetrically welded to the bottom of the end plate. Fixing boxes are symmetrically embedded inside both ends of the end plate. A bidirectional screw is rotatably connected between the fixing box and the end plate. Threaded blocks are symmetrically threaded to both ends of the bidirectional screw. An insert plate is slidably connected inside one side of the fixing box. An installation groove is opened inside one side of the insert plate. A fixing plate is symmetrically welded to one side of the threaded block. A movable rod is symmetrically rotatably connected between the installation groove and the fixing plate. A support plate is symmetrically fixedly installed on the top of the support column, and a slot is opened on one side of the support plate.

[0009] Preferably, sliders are symmetrically welded on both the upper and lower sides of the insert plate, and sliding grooves are symmetrically opened on the inner side of the fixing box, and the sliders are slidably connected to the sliding grooves.

[0010] Preferably, the limiting component includes a pin disposed on one side of the support column, and a first connecting ring is fixedly installed on the top of the pin, and a second connecting ring is fixedly installed on one side of the support column, and a connecting rope is fixedly installed between the first connecting ring and the second connecting ring.

[0011] Preferably, the outer side of the limiting block fits into the inner side of the limiting groove, and the limiting block and the limiting groove are interlocked.

[0012] Preferably, the outside of the insert plate fits into the inside of the slot, and the insert plate and the slot are plugged in.

[0013] Preferably, the side of the threaded block away from the movable rod is in contact with the inner side of the fixed box.

[0014] Preferably, the end plate is inserted into the support plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This highway slope safety protection device is specifically designed as follows: Limiting plates are inserted into corresponding limiting slots, and limiting blocks are inserted into the top of the limiting slots. Workers rotate two sets of bidirectional screws inside the fixing box, and the movement and rotation of the movable rod pushes or pulls the insert plate to slide inside the fixing box. At this time, the insert plate and slot are connected, thus achieving the effect of quick installation and disassembly of the protective net. Multiple sets of protective nets can be quickly spliced ​​together, which is more convenient than the existing method of fixing guardrails with multiple sets of bolts and nuts. This design achieves quick initial installation and locking of multiple sets of protective nets, convenient and efficient splicing, and allows for direct extraction and individual repair of damaged protective nets without overall disassembly, making maintenance more convenient. Workers insert pins into the roadside soil, and then wrap connecting ropes between the first and second connecting rings. The connecting ropes reduce the forward tilting of the protective net, greatly improving the protective effect of the net on slope stabilization and significantly enhancing the safety of the device during use.

[0016] 1. The installation frame is placed between the support columns by the staff. At this time, the limiting plates are inserted into the corresponding limiting slots. Then, the end plate is placed on top of the support columns, and the limiting blocks are inserted into the top of the limiting slots. The end plate is then inserted between the support plates. The staff then rotates two sets of bidirectional screws inside the fixing box. The rotation of the bidirectional screws causes the two sets of threaded blocks to move in a convergent and unfolding trajectory. The movement of the threaded blocks causes the movement of two sets of movable rods. The movement of the movable rods rotates and pushes or pulls the insert plate to slide inside the fixing box. At this time, the insert plate is inserted into the slot, thus enabling... This design enables rapid installation and disassembly of protective netting, allowing for quick splicing of multiple netting units. Compared to existing technologies that use multiple bolts and nuts to fix guardrails, this design is more convenient. It enables rapid initial installation and locking of multiple netting units, with convenient and efficient splicing. When a single netting unit is damaged, it can be pulled out for individual repair without overall disassembly, making maintenance more convenient. The movement of the insert plate drives two sets of sliders to slide inside the groove, thereby achieving the effect of limiting the sliding of the insert plate. This effectively prevents the insert plate from falling off due to excessive movement, greatly improving the stability of the device during use.

[0017] 2. The staff inserts the pin into the roadside soil, and then wraps the connecting rope between the first and second connecting rings. When rocks fall from the slope and impact the protective net, the connecting rope can reduce the forward tilting of the protective net, greatly improving the protective effect of the protective net on slope stabilization and other protections, and greatly improving the safety of the device during use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a highway slope safety protection device, including an installation frame 1, a protective net 101 fixedly installed inside the installation frame 1, and support columns 102 symmetrically arranged on both sides of the installation frame 1, and a base 103 fixedly installed at the bottom of the support columns 102; a fixing mechanism 2 is provided between the installation frame 1 and the support columns 102, and a limit component 3 is provided on the reverse side of the support columns 102;

[0026] The fixing mechanism 2 includes a limiting plate 201, which is symmetrically fixedly installed on both sides of the mounting frame 1. Limiting grooves 202 are symmetrically formed on both sides of the support column 102. An end plate 203 is provided at the top of the support column 102, and limiting blocks 204 are symmetrically welded to the bottom of the end plate 203. The exterior of the limiting block 204 fits into the interior of the limiting groove 202, and the limiting block 204 is inserted into the limiting groove 202. Fixing boxes 205 are symmetrically embedded inside both ends of the end plate 203. A bidirectional screw 206 is rotatably connected between the fixing box 205 and the end plate 203. Threaded blocks 207 are symmetrically threaded to the exterior of both ends of the bidirectional screw 206. An insert plate 208 is slidably connected to one side of the fixing box 205, and an installation groove 209 is formed inside one side of the insert plate 208. Fixing plates 2091 are symmetrically welded to one side of the threaded blocks 207. Furthermore, a movable rod 210 is symmetrically rotatably connected between the mounting groove 209 and the fixing plate 2091. The side of the threaded block 207 away from the movable rod 210 is in contact with the inner side of the fixing box 205. Moreover, a support plate 211 is symmetrically fixedly installed on the top of the support column 102. The outer side of the end plate 203 is inserted into the support plate 211. A slot 212 is opened on one side of the support plate 211. The outer side of the insert plate 208 is in contact with the inner side of the slot 212. The insert plate 208 is inserted into the slot 212. This enables the quick installation and disassembly of the protective net 101. Multiple sets of protective nets 101 can be quickly spliced. Compared with the existing technology of fixing guardrails with multiple sets of bolts and nuts, this design is more convenient. This design not only enables the quick initial installation and locking of multiple sets of protective nets 101, but also makes splicing convenient and efficient. When a single protective net 101 is damaged, it can be directly pulled out for individual repair without the need for overall disassembly, making maintenance more convenient.

[0027] Slider 213 is symmetrically welded on both the upper and lower sides of the insertion plate 208, and sliding grooves 214 are symmetrically opened on the inner side of the fixing box 205. The slider 213 and the sliding groove 214 are slidably connected, thereby achieving the effect of limiting the sliding of the insertion plate 208. This effectively avoids the phenomenon of the insertion plate 208 falling off due to excessive movement, and greatly improves the stability of the device during use.

[0028] The limiting component 3 includes a pin 301 disposed on the opposite side of the support column 102, and a first connecting ring 302 is fixedly installed on the top of the pin 301, and a second connecting ring 303 is fixedly installed on the opposite side of the support column 102. A connecting rope 304 is fixedly installed between the first connecting ring 302 and the second connecting ring 303. When the slope rocks fall and impact the protective net 101, the connecting rope 304 can reduce the forward tilting of the protective net 101, greatly improving the protective effect of the protective net 101 against slope rocks and greatly improving the safety of the device during use.

[0029] Working principle: Before using this type of highway slope safety protection device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, firstly, the workers evenly place the support columns 102 near the collapsed area of ​​the highway slope. Then, the workers place the installation frame 1 between the support columns 102. At this time, the limiting plates 201 are inserted into the corresponding limiting grooves 202. Next, the workers place the end plates 203 on top of the support columns 102. At this time, the limiting blocks 204 are inserted into the top of the inner side of the limiting grooves 202. At this time, the end plates 203 are inserted between the support plates 211. Then, the workers rotate the two sets of bidirectional screws 206 inside the fixing box 205. The rotation of the bidirectional screws 206 drives the two sets of threaded blocks 207 to move in a convergent and unfolding trajectory. The movement of the threaded blocks 207 drives the movement of the two sets of movable rods 210. The movement and rotation of the movable rods 210 push or pull the insert plate 208. The fixed box 205 slides inside, at which time the insert plate 208 is inserted into the slot 212, thereby realizing the effect of quick installation and disassembly of the protective net 101. Multiple sets of protective nets 101 can be quickly spliced ​​together, which is more convenient than the existing technology of fixing guardrails with multiple sets of bolts and nuts. This design not only realizes the quick initial installation and locking of multiple sets of protective nets 101, but also makes splicing convenient and efficient. When a single protective net 101 is damaged, it can be directly pulled out for individual repair without the need for overall disassembly, making maintenance more convenient. The movement of the insert plate 208 drives the two sets of sliders 213 to slide inside the slide groove 214, thereby realizing the effect of limiting the sliding of the insert plate 208, which can effectively prevent the insert plate 208 from falling off due to excessive movement, and greatly improve the stability of the device during use.

[0030] Workers insert the pin 301 into the roadside soil, and then wrap the connecting rope 304 between the first connecting ring 302 and the second connecting ring 303. When rocks fall from the slope and impact the protective net 101, the connecting rope 304 can reduce the forward tilting of the protective net 101, greatly improving the protective effect of the protective net 101 on slope stabilization and other protection, and greatly improving the safety of the device during use.
