Description

Technical Field

[0001] This application relates to the field of slope protection technology, and in particular to a slope protection device for engineering construction. Background Technology

[0002] In road and building construction, slope protection is a key safety guarantee. Its core function is to prevent rocks and sand from falling from the slope, thus avoiding accidents such as injuries to construction workers and damage to equipment caused by falling materials.

[0003] To prevent rocks and sand from rolling down the slope during construction, workers lay a protective net on the slope to block the falling rocks and sand, which effectively protects personnel and equipment during construction. After construction is completed, the protective net needs to be removed and vegetation planted on the slope to reduce soil erosion. However, since the protective net is rolled up directly at the top of the slope, the rolling up process can drag rocks and sand, causing them to roll down.

[0004] Therefore, those skilled in the art provide a slope protection device for engineering construction to solve the problems mentioned in the background art. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a slope protection device for engineering construction.

[0006] The slope protection device for engineering construction provided in this application adopts the following technical solution:

[0007] A slope protection device for engineering construction includes a winding roller with a protective net wound around it. Both ends of the winding roller are rotatably connected to movable frames. The lower ends of the two movable frames are vertically slidably connected to insert rods, and the upper ends of the insert rods are threaded with nuts. One end of each of the two movable frames is equipped with an inclined support rod. The bottom ends of each of the two support rods are slidably connected to sliding sleeves. One side of each sliding sleeve is fixed with a cable, and the other ends of each cable are fixedly connected to both sides of the end of the protective net. Both sides of the bottom of the protective net are fixed with pull ropes. One end of each pull rope is fixed with a collar, and each collar has an insert rod fitted inside it.

[0008] In this invention, the nut penetrates the inner wall of the insert rod (not shown in the figure) and contacts the outer surface of the movable frame, and is used to press the movable frame.

[0009] Preferably, one of the movable frames has a sliding groove, and a V-shaped movable rod is vertically slidably connected to the sliding groove. One end of the movable rod is rotatably connected to a pressure column, which presses against the outer surface of the upper end of the protective net.

[0010] Preferably, the movable frame is rotatably connected to a screw inserted into the slide groove, and the screw is threadedly connected to one end of the movable rod.

[0011] Preferably, each of the two movable frames is fixed to one side with a fixed seat, and the upper ends of the two support rods are threadedly connected to the two fixed seats respectively.

[0012] Preferably, the outer walls of the insertion rod and the insertion post are fixed with limit plates, the upper end of the insertion post is provided with a U-shaped groove, and one end of the winding roller is fixed with a crank handle.

[0013] Preferably, the bottom end of the support rod is provided with a threaded groove, which is used to thread a threaded rod, and an extension rod is fixed to one end of the threaded rod.

[0014] In this utility model, the fixing methods of the slope top insertion rod and slope foot insertion post ensure that the protective net is stable and reliable after it is deployed and is not easily displaced by external forces. The movable frame can be fixed by squeezing with nuts to meet the usage needs of different construction scenarios.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. This application, by inserting a hammer into the top of the slope to fix the winding roller, and inserting a hammer into the bottom of the slope to tighten the protective net with a collar and a rope, can quickly cover the slope with the protective net, effectively blocking falling rocks and rolling sand from the slope, directly avoiding the risk of personnel injury during construction, and providing core protection for on-site construction safety.

[0017] 2. When winding, the movable frame is moved upward and fixed to allow the protective net to rise and detach from the slope surface. Then, the winding roller is rotated to wind the net. This can completely avoid the protective net dragging down rocks and sand from the slope during the winding process, thus eliminating secondary safety hazards caused by material rolling off during the net winding stage and improving operational safety.

[0018] 3. On the one hand, the winding roller can be turned by cranking the handle to complete the winding, and the design of the collar sliding along the support rod simplifies the net winding operation; on the other hand, the cooperative structure of the pressure column, screw and movable rod can not only enhance the protective fit by pressing down on the protective net, but also assist in the winding and unwinding of the protective net.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] like Figure 1-5As shown, this application discloses a slope protection device for engineering construction, including a winding roller 11, on which a protective net 2 is wound. Movable frames 12 are rotatably connected to both ends of the winding roller 11. Insert rods 1 are vertically and slidably connected to the lower ends of the two movable frames 12, and nuts 22 are threadedly connected to the upper ends of the insert rods 1. Inclined support rods 4 are installed at one end of each of the two movable frames 12. Sliding sleeves 9 are slidably connected to the bottom ends of the two support rods 4. Cables 10 are fixed to one side of each of the two sliding sleeves 9, and the other ends of the two cables 10 are respectively connected to the protective net 2. The protective netting 2 is fixedly connected to both ends; pull ropes 8 are fixed to both sides of the bottom end of the protective netting 2, and a collar 7 is fixed to one end of each of the two pull ropes 8. Inserted posts 3 are fitted inside each of the two collars 7. The user hammers the two inserted posts 1 into the top of the slope to support the protective netting 2 on the winding roller 11, and hammers the two inserted posts 3 into the foot of the slope. When the protective netting 2 is unrolled and extended downwards, the two collars 7 are respectively fitted onto the two inserted posts 3. The protective netting 2 is then tightened using the collars 7 and pull ropes 8 until it covers the slope, protecting the slope and preventing it from falling. To prevent stones and sand from rolling down and causing injury to personnel during construction, when the protective netting 2 needs to be rolled up at the end of construction, two people work together at the top and bottom of the slope to move the two movable frames 12 upwards. They tighten the nuts 22 to compress the movable frames 12, preventing them from sliding down. Then, they move the two collars 7 upwards to disengage from the posts 3 and insert the collars 7 into the bottom of the support rods 4. During the upward movement of the movable frames 12, the winding rollers 11 and the wound protective netting 2 move upwards, along with the two support rods 4, the sliding sleeves 9, the cables 10, and the netting laid on the slope. The protective netting 2 on the slope moves upward until it detaches from the upper surface of the slope. Then, the handle 13 is held and the winding roller 11 is rotated to wind up the protective netting 2. This causes the bottom end of the protective netting 2 to move upward, driving the sliding sleeve 9 to slide up along the support rod 4, and also driving the collar 7 to slide up along the support rod 4, until the protective netting 2 is wound onto the winding roller 11. Since the protective netting 2 moves upward and detaches from the upper surface of the slope before winding, it will not drag the falling rocks and sand on the slope during the winding process, thus avoiding the rolling of falling rocks and sand during the winding process.

[0027] After the protective netting 2 is rolled up, use a tool (not shown) to remove the insert rod 1 and the insert post 3, store the protective netting 2, and proceed to the next construction slope protection project.

[0028] It should be noted that when laying the protective netting 2 on the slope, the protective netting 2 can be rolled up on the top of the slope first, and then the poles 1 and posts 3 can be hammered into the top and bottom of the slope respectively until the protective netting 2 is laid on the slope, which reduces the rolling of rocks and sand during the process of laying the protective netting on the slope.

[0029] One of the movable frames 12 has a sliding groove 16, and a V-shaped movable rod 6 is vertically slidably connected to the sliding groove 16. One end of the movable rod 6 is rotatably connected to a pressure post 5, which presses on the upper outer surface of the protective net 2. Pressing a pressure post 5 on the upper surface of the protective net 2 is beneficial for the winding and unwinding of the protective net 2.

[0030] The movable frame 12 is rotatably connected to a screw 15 inserted into the slide groove 16. The screw 15 is threadedly connected to one end of the movable rod 6. By manually rotating the screw 15, the movable rod 6 moves down, which drives the pressure column 5 to move down and press down on the protective net 2. This helps the protective net 2 to stick to the slope for protection and prevent rocks and sand from rolling down.

[0031] Each of the two movable frames 12 has a fixed seat 14 on one side, and the upper ends of the two support rods 4 are threaded to the two fixed seats 14 respectively. The support rods 4 are threaded to the movable frames 12, which facilitates the disassembly and installation of the support rods 4. When the protective net 2 is rolled up on the winding roller 11, the support rods 4 can be rotated and disassembled, which facilitates the recycling, movement, transportation and reuse of the protective net 2.

[0032] Both the insert rod 1 and the insert post 3 have a limiting plate 17 fixed on their outer walls. The upper end of the insert post 3 has a U-shaped groove 21. One end of the winding roller 11 is fixed with a crank 13. The limiting plate 17 is used to press on the upper surface of the slope to support the insert rod 1 and the insert post 3. The groove 21 is set to prevent the insert post 3 from blocking the support rod 4.

[0033] The bottom end of the support rod 4 is provided with a threaded groove 19, which is used to thread the threaded rod 20. One end of the threaded rod 20 is fixed with an extension rod 18. The extension rod 18 is threadedly connected to the lower end of the support rod 4 through the cooperation of the threaded rod 20 and the threaded groove 19, which increases the length of the support rod 4 and makes it easier to adjust the unwinding length of the protective net 2 according to the length of the slope, so that the support rod 4 and the extension rod 18 can support the collar 7.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] Working principle: Two personnel work together at the top and bottom of the slope to move the two movable frames 12 upwards. By tightening the nuts 22, the movable frames 12 are compressed to prevent them from moving downwards. Then, the two collars 7 are moved upwards to disengage from the inserts 3, and the collars 7 are slipped onto the bottom of the support rods 4. During the upward movement of the movable frames 12, the winding rollers 11 and the wound protective netting 2 are moved upwards, which in turn moves the two support rods 4, the sliding sleeves 9, the cables 10, and the protective netting 2 laid on the slope upwards until the protective netting 2... Once the netting is detached from the upper surface of the slope, the handle 13 can be gripped to rotate the winding roller 11 and rewind the protective netting 2. This causes the bottom end of the protective netting 2 to move upward, causing the sliding sleeve 9 to slide up along the support rod 4, and also causing the collar 7 to slide up along the support rod 4 until the protective netting 2 is rewinding onto the winding roller 11. Because the protective netting 2 moves upward and detaches from the upper surface of the slope before rewinding, it will not drag rocks or sand on the slope during the rewinding process, thus preventing rocks and sand from rolling down during the rewinding process.

[0037] 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 preferred examples and are not intended to limit the utility model.
