Description

Technical Field

[0001] This invention relates to the field of slope protection railing technology, specifically to a slope wind-resistant warning and protection railing that is easy to expand. Background Technology

[0002] When constructing in environments containing slopes, safety barriers must be installed around the slopes to ensure safety.

[0003] Existing guardrails are generally large in size, have a large windward area, and are relatively bulky in structure. They are suitable for use as fencing in fixed construction areas or as protective fencing for smaller construction areas.

[0004] The filling and paving of gullies in the wild typically involves a large construction area, usually located in remote areas. The process usually begins at the bottom of the gully, with the construction area expanding upwards and outwards as construction progresses. This requires not only setting up protective fences to enclose the slopes and ensure construction safety, but also adapting the fences to the expanding area. For example, in actual construction, the protective fences often need to be dismantled, moved, and expanded approximately twice a day. Using existing fences not only involves a large amount of work in dismantling, moving, and replacing them, but also makes the work time-consuming, labor-intensive, and slow, making it unsuitable for large-scale filling and paving of gullies in the wild. If simple fencing measures are used, such as poles connected to ropes, reflective strips and flags attached to the ropes, flashing lights on the poles, and warning signs, these measures are insufficient to meet the required protection standards.

[0005] Therefore, there is an urgent need for a protective fence that can solve the above problems. Summary of the Invention

[0006] The present invention aims to provide a slope wind-resistant warning and protection railing that is easy to manage and use, convenient to assemble and disassemble, relocate, and connect securely and reliably, and whose expansion capability reduces the amount of supplementary components required as the protected area increases.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The present invention provides an easily expandable slope wind-resistant warning and protection railing, comprising several rigid pipes and several pipe joints. The rigid pipe includes a pipe body, one end of which is provided with a pointed tip, the other end with a slot, and both ends are provided with a first insertion hole.

[0009] The pipe fitting includes a core plug and a first conical nut. The core plug includes an expansion tube, a bolt threaded to the upper end of the expansion tube, and a horizontal plug symmetrically connected to the outer wall of the expansion tube. The horizontal plug includes a connecting plate, an external threaded cylinder, and an arc-shaped groove. The concave surface of the arc-shaped groove has a protruding post, one end has several slots, and the other end is connected to one end of the external threaded cylinder. The connecting plate is connected between the other end of the external threaded cylinder and the outer wall of the expansion tube, and the long side of the connecting plate is parallel to the axis of the expansion tube. The first conical nut is sleeved on the outside of the arc-shaped groove and threadedly connected to the external threaded cylinder.

[0010] The expansion tube is inserted into the slot end of the tube body. Tightening the bolt can expand the lower part of the expansion tube, thereby achieving a fixed connection between the expansion tube and the tube body.

[0011] The connecting plate is inserted into the slot;

[0012] The protrusion is inserted into the first insertion hole.

[0013] Preferably, the rigid pipe is a steel pipe.

[0014] Preferably, the center line of the first insertion hole is parallel to the axis of the tube body.

[0015] Preferably, the arc-shaped groove has a groove opening end connected to a plurality of wedge blocks. The wedge blocks are used to slide the inner surface of the conical end of the first conical nut on the wedge blocks during the tightening process of the first conical nut, and push the groove opening end of the arc-shaped groove to contract inward, so as to promote the pipe joint to clamp the rigid pipe.

[0016] Preferably, the easily expandable slope wind-resistant warning guardrail further includes a pipe connector, which includes a second sleeve, a third hand-tightening screw threaded to the second sleeve, and two U-shaped grooves evenly connected to the outer wall of the second sleeve. A limiting member is connected to one end of the U-shaped groove near the second sleeve. The second sleeve is fitted onto the lower part of the rigid pipe with the expansion tube inserted. The U-shaped groove is used to connect a spare rigid pipe and serves as a foot pedal for inserting the rigid pipe with the expansion tube into the ground. The limiting member is used to confine the spare rigid pipe inserted into the U-shaped groove, preventing it from being pulled out, and also to connect the U-shaped groove to the spare rigid pipe, improving the anti-collapse capability of the rigid pipe assisted by the U-shaped groove.

[0017] Preferably, the limiting component is a hand-tightening screw.

[0018] Preferably, the easily expandable slope wind-resistant warning and protection railing further includes a three-end connector and a flexible pipe. The three-end connector includes a core connector, a first hand-tightening screw and a second conical nut. The core connector includes a first sleeve and a horizontal connector symmetrically connected to the outer wall of the first sleeve. The horizontal connector is formed by removing the connecting plate from the horizontal connector. The second conical nut is threaded to the horizontal connector. The first hand-tightening screw is threaded to the wall of the first sleeve. The first sleeve is fitted into the middle of the rigid pipe into which the expansion tube is inserted.

[0019] The flexible tube includes a waterproof fabric tube and a flashlight detachably connected to both ends of the waterproof fabric tube. One end of the flashlight is detachably connected to a tail cap, and the side wall of the tail cap is provided with a second insertion hole for connecting the horizontal connector. The other end of the flashlight is provided with a lamp head, which is inserted into the waterproof fabric tube. A switch is provided on the wall of the flashlight near the lamp head end. A vent is provided at the bottom of the waterproof fabric tube. The vent is used to expel air from the waterproof fabric tube when it is folded, making it easy to fold. When the waterproof fabric tube is stretched, air can enter to allow the waterproof fabric tube to open.

[0020] Preferably, the switch is a light-controlled switch.

[0021] Preferably, the waterproof fabric tube is made of nylon fabric.

[0022] Preferably, the flashlight has an annular groove on the wall near the lamp head.

[0023] Preferably, both ends of the waterproof pipe are connected to the annular groove via pipe clamps.

[0024] Preferably, the rigid tube and / or the waterproof fabric tube are provided with reflective rings or reflective strips on the outside, which are made of reflective material rolled into a ring shape or formed by brushing reflective paint.

[0025] Preferably, the rigid tube and / or the waterproof fabric tube are connected to the outside of a colored flag 7.

[0026] Preferably, a strobe light is connected to the upper end of the bolt.

[0027] Preferably, a warning sign is attached to the rigid tube.

[0028] Due to the adoption of the above technical solutions, the advantages of this invention are as follows:

[0029] 1. The easily expandable slope wind-resistant warning and protection railing provided by the present invention includes a pipe joint on which a certain number of reserve rigid pipes can be connected. With the support of the reserve rigid pipes, it is not only beneficial to improve the stability of the railing, but also beneficial to reduce the depth of the rigid pipes inserted into the ground, thereby reducing labor intensity and improving construction efficiency.

[0030] 2. As the construction area expands, when the present invention is moved and installed again, since a certain number of reserve rigid pipes can be connected to the insertion joint, the number of additional rigid pipes can be reduced or eliminated.

[0031] 3. The rigid pipe can be easily and quickly pulled out of the ground by lifting the end of the spare rigid pipe closest to the second hand-tightening screw. Unlike the existing operation method, which requires workers to manually pull the loose rigid pipe out of the ground after shaking it multiple times until it is loose, the rigid pipe can be easily and quickly pulled out of the ground.

[0032] 4. The slope wind-resistant warning and protection railing provided by the present invention includes a pipe joint that can be used as a foothold for construction workers to insert rigid pipes into the ground, which can save the trouble and weight of carrying special pipe insertion tools during construction.

[0033] 5. As the construction area expands, when the invention is moved and installed again, it can be disassembled into two parts that are easy to move and install simply by turning the strobe light. This not only eliminates the need to carry disassembly and assembly tools, but also makes the disassembly and assembly operation simpler and more efficient.

[0034] 6. In this invention, the two ends of the horizontally connected rigid tube are connected to the pipe joint by a plug-in clamping connection. This not only makes the connection convenient, but also makes it difficult for the horizontally connected rigid tube to fall off the pipe joint because the first plug hole on the rigid tube is plugged into the protrusion in the pipe joint, thus ensuring a reliable connection.

[0035] 7. The pipe fitting included in this invention is inserted and clamped to the upper end of the rigid pipe through an expansion tube. The pipe fitting is unlikely to loosen and fall off, thus ensuring the protective reliability of the rigid pipe connected laterally in this invention.

[0036] 8. The flexible tube provided by this invention is not only easy to fold, but also has a circular cross-section, resulting in less wind resistance than a planar warning strip. It also has a better multi-angle visibility area and a better warning effect. In addition, under the control of the light-controlled switch, when the light dims, the flashlight at the end of the flexible tube illuminates the inside of the waterproof fabric tube. The light shines through the outer wall of the waterproof fabric tube, thus achieving a significant warning effect when the light is insufficient. The flashlight-like light source setting also avoids the drawbacks of setting up a light strip inside the waterproof fabric tube, which is costly, not resistant to folding, and consumes more electricity.

[0037] 9. This invention requires only one type of rigid tube, which not only has good versatility but also makes management and use more convenient.

[0038] 10. The present invention has a simple structure and low cost. Attached Figure Description

The first hand-tightening screw 43 is threadedly connected to the wall of the first sleeve 411. The first sleeve 411 is fitted into the middle of the rigid tube 1 into which the expansion tube 212 is inserted. See [link to relevant documentation]. Figure 1 , Figure 11 , Figure 12 ;

[0063] The flexible tubing 5 includes a waterproof fabric tube 54 and a flashlight 51. One end of the flashlight 51 is detachably connected to a tail cap 514. The side wall of the tail cap 514 has a second insertion hole 10 for connecting to the horizontal connector 412. The other end of the flashlight 51 has a lamp head 512, which is inserted into the waterproof fabric tube 54. The wall of the flashlight 51 near the lamp head 512 has an annular groove 511 and a light control switch 513. The bottom of the waterproof fabric tube 54 has a vent hole, and colorful flags 7 are attached to the outside. Both ends of the waterproof fabric tube 54 are tightly connected to the annular groove 511 of a flashlight 51 by a pipe clamp 52 and a rubber sleeve 53, respectively. See [link / reference needed]. Figure 1 , Figure 13 ;

[0064] The insertion connector 6 includes a second sleeve 61, a third hand-tightening screw 64 threadedly connected to the second sleeve 61, and two U-shaped grooves 62 evenly connected to the outer wall of the second sleeve 61. A second hand-tightening screw 63 is threaded to one end of each U-shaped groove 62 near the second sleeve 61. The second sleeve 61 is fitted onto the lower part of the rigid tube 1 into which the expansion tube 212 is inserted. See [reference needed]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 ;

[0065] Three pipe fittings 2 are respectively inserted into the end of a rigid pipe 1 with a slot 112 through their expansion tubes 212;

[0066] The pointed ends 111 of the three rigid pipes 1 with pipe fittings 2 are used for vertical insertion into the ground;

[0069] The warning sign 20 is attached to a rigid pipe 1 that is connected to the arc groove 216.

[0070] In this embodiment, the rigid tube 1 is made of steel pipe; the waterproof fabric tube 54 is made of nylon fabric; and reflective rings 8 are coated on the outside of both the rigid tube 1 and the waterproof fabric tube 54 at intervals.

[0071] Obviously, the length of the guardrail can be adjusted by increasing or decreasing the length of the guardrail based on the above embodiment, according to the slope area that needs to be fenced off, to adapt to the actual protection area.

[0072] The first method of using this invention:

[0073] S1. Deployment of guardrail components: Based on the initial construction area of ​​the ditch to be enclosed, deploy the guardrail components provided by this invention at one or more points in the selected guardrail layout area.

[0074] S2. Connect the flexible tube 5 to the three-end connector 4. Unscrew the second conical nut 42 on the three-end connector 4 and put it on the end cap 514 of the flashlight 51. Then insert the end cap 514 of the flexible tube 5 into the arc groove 216 of the horizontal connector 412 and insert the protrusion 2163 into the second insertion hole 10. Then screw the second conical nut 42 to connect with the horizontal connector 412 (as the second conical nut 42 is tightened on the horizontal connector 412, the inner surface of the conical section of the second conical nut 42 presses against the end of the arc groove 216, so that the end of the arc groove 216 clamps the flashlight 51). If it has been pre-connected, this step can be omitted.

[0075] S3. The first sleeve 411 is fitted onto the rigid tube 1, and the first hand-tightening screw 43 is turned to position the first sleeve 411 on the rigid tube 1.

[0076] S4. Connect the insertion connector 6 to the lower part of the rigid tube 1 connected to the first sleeve 411, and tighten the third hand screw 64 to position the insertion connector 6 on the rigid tube 1.

[0077] S5. Place the middle part of the spare rigid tube 1 into the U-shaped groove 62 and lock it in place by tightening the second hand-tightening screw 63 (this step can also be placed after S6).

[0078] S6. The construction worker holds the upper part of the rigid pipe 1 connected to the first sleeve 411 with his hand, steps on the top of the U-shaped groove 62 with his foot, and inserts the pointed end 111 into the ground until the bottom of the U-shaped groove 62 contacts the ground.

[0079] S7. Insert the expansion tube 212 of pipe connector 2 into the upper end of the rigid pipe 1 that has been inserted into the ground (or it can be connected in advance). Then, screw on the strobe light 3 connected to the bolt 211 to expand the expansion tube 212 and fix the pipe connector 2 and rigid pipe 1 in place. Then, connect the horizontal rigid pipe 1 between the horizontal plugs 213 of adjacent pipe connectors 2 (see...). Figure 6 (If you have already connected beforehand, this step can be omitted);

[0080] S8. Finally, hang a warning sign 20 on the horizontally connected rigid pipe 1.

[0081] As the construction area expands, the method for relocating and reinstalling this invention is as follows:

[0082] At this point, due to the longer guardrail, construction workers need to carry additional components included in this invention, such as pipe connectors 2, flashing lights 3, and three-terminal connectors 4. Since a certain number of rigid pipes 1 have already been connected to the pipe connectors 6, they generally do not need to be carried again. However, if the protected area expands too much, a certain number of additional pipes will need to be carried as needed.

[0083] S1. The construction worker holds the spare rigid pipe 1 and lifts it up from the second hand-tightening screw 63 to pry the rigid pipe 1 out of the ground (if there is a hanging warning sign 20, remove the warning sign 20 first and hang it up again when needed).

[0084] S2. Tighten the strobe light 3 to release the pipe connector 2 from the rigid pipe 1 (as the bolt 211 moves upward, the expansion tube 212 contracts and no longer clamps the inner wall of the rigid pipe 1), and then separates from the rigid pipe 1. See the section after separation for details. Figure 3 , Figure 6 If there are many construction workers and the guardrail is short, this step can be omitted, and the entire guardrail can be moved.

[0085] S3. After moving the two parts separated in S2 to the new location to be set, remove the spare rigid tube 1 connected to the cannula connector 6, and replenish the required rigid tube 1 according to the method described in the first use (or, in step S1 or S2, loosen the second hand-tightening screw 63, remove the spare rigid tube 1 from the cannula connector 6 in advance before moving it), and... Figure 3 The part shown is unfolded so that the pointed end 111 points to the ground position to be inserted. Depending on the number of construction workers, the rigid pipe 1 can be inserted into the ground one by one or multiple times at the same time, in the manner described above.

[0086] S4, will Figure 6 The expansion tube 212 of the pipe connector 2 shown is inserted into the upper end of the rigid pipe 1 that has been inserted into the ground, and then the strobe light 3 is screwed on until the pipe connector 2 is fixedly connected to the upper end of the rigid pipe 1 that has been inserted into the ground.

[0087] As the construction area continues to expand, the above-described method of relocation and installation can be used as a reference, and the necessary components included in this invention, such as the rigid pipe 1, pipe connector 2, strobe light 3, and three-terminal connector 4, can be carried along.

[0088] If the spare rigid tube 1 below the insertion connector 6 has been used up, the third hand-tightening screw 64 can be loosened to move the insertion connector 6 upwards a certain distance, allowing the rigid tube 1 used for insertion into the ground to be inserted deeper into the ground, increasing stability. If it is necessary to pull the rigid tube 1 inserted into the ground out at this time, the first conical nuts 22 at both ends of a horizontal rigid tube 1 can be loosened to remove the rigid tube 1, which can be used as a pry bar under the U-shaped groove 62 of the insertion connector 6. If there is still a spare rigid tube 1 connected below the insertion connector 6, the insertion connector 6 can be moved downwards a certain distance to insert the rigid tube 1 used for insertion into the ground relatively shallowly, thereby improving construction speed and reducing labor intensity.

[0089] The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
