Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a portable construction safety protection fence. Background Art

[0002] In the field of building construction, in order to ensure the safety of workers and prevent non-staff from straying into dangerous areas, it is usually necessary to set up safety protection fences at the construction site. Most of the traditional safety protection fences adopt a structure with fixed dimensions, which leads to certain limitations in their actual application. These fences often cannot well adapt to construction sites of different shapes and sizes. In addition, traditional fences are usually heavy and not easy to carry, and the installation and disassembly processes are also relatively complex, time-consuming and laborious.

[0003] In view of the above problems, there have been foldable and telescopic fences in the prior art to solve the problems of handling, installation and disassembly. For example, the Chinese invention patent "A protection fence structure for municipal engineering" with the publication number CN113202341A specifically discloses a protection fence structure for municipal engineering, which includes a number of connected fence units. Each fence unit includes a first rod body and a second rod body arranged vertically. A number of first folding members and second folding members arranged in parallel and at intervals are connected between the first rod body and the second rod body, and a rotating connecting member is connected between the first folding member and the second folding member. In this application, an included angle can be formed between adjacent first folding members and second folding members through the rotating connecting member, so that the fence structure can more easily adapt to the shape of the periphery of the construction site, and thus the position reserved for the passage of pedestrians and vehicles can be increased, and the adaptability is better.

[0004] However, when the above prior art is applied to the construction site, there are obvious problems. Since the extended fence structure is in a straight line form, it can only effectively enclose one side of the construction point. For construction points that require all-round protection, this is a significant limiting factor, resulting in a reduction in the safety of the entire construction area. To achieve all-round protection, four identical devices are required to enclose the four sides of the construction point. In this way, not only does it increase the cost of purchasing and maintaining the equipment, but it may also increase the overall project budget. At the same time, it means that more labor and time are required for each handling and installation. This poses a severe challenge for frequently moving construction sites, especially in limited spaces. Moreover, four fence units require a larger storage space, which may become a problem for construction teams with limited storage facilities. Summary of the Invention

[0005] To solve the above technical problems, the present application provides a portable construction safety protection fence, which includes a support assembly, a first enclosure assembly, and a second enclosure assembly. The support assembly includes an upper arc-shaped block, a lower arc-shaped block, and a plurality of third telescopic rods. One end of the third telescopic rod is connected to the lower arc-shaped block, and the other end is connected to the upper arc-shaped block. The third telescopic rod can drive the upper arc-shaped block to move up and down in the vertical direction. The upper arc-shaped block and the lower arc-shaped block are both provided with opposite first sliding grooves and second sliding grooves; the first enclosure assembly is arranged in the first sliding groove and can slide along the extension line of the first sliding groove. The first enclosure assembly is in limit fit with the first sliding groove; the second enclosure assembly is arranged in the second sliding groove and can slide along the extension line of the second sliding groove in a direction opposite to that of the first enclosure assembly. The second enclosure assembly is in limit fit with the second sliding groove.

[0006] Preferably, the first enclosure assembly includes a first upper arc-shaped sliding rod, a first lower arc-shaped sliding rod, and a plurality of first telescopic rods.

The first upper arc-shaped sliding rod and the first lower arc-shaped sliding rod are both in limit fit with the first sliding groove. One end of the first telescopic rod is connected to the first upper arc-shaped sliding rod, and the other end is connected to the first lower arc-shaped sliding rod. The first telescopic rod can drive the first upper arc-shaped sliding rod to move up and down in the vertical direction.

[0007] Preferably, the second enclosure assembly includes a second upper arc-shaped sliding rod, a second lower arc-shaped sliding rod, and a plurality of second telescopic rods. The second upper arc-shaped sliding rod and the second lower arc-shaped sliding rod are respectively arranged in the second sliding grooves on the upper arc-shaped block and the lower arc-shaped block, and the second upper arc-shaped sliding rod and the second lower arc-shaped sliding rod can slide along the second sliding groove simultaneously. The second upper arc-shaped sliding rod and the second lower arc-shaped sliding rod are both in limit fit with the second sliding groove. One end of the second telescopic rod is connected to the second upper arc-shaped sliding rod, and the other end is connected to the second lower arc-shaped sliding rod. The second telescopic rod can drive the second upper arc-shaped sliding rod to move up and down in the vertical direction.

[0008] Preferably, locking members are arranged on the first upper arc-shaped sliding rod and the second upper arc-shaped sliding rod. The locking members include a rotating buckle hinged on the first upper arc-shaped sliding rod and a positioning pin arranged on the second upper arc-shaped sliding rod. The positioning pin can be locked with the rotating buckle.

[0009] Preferably, the first telescopic rod, the second telescopic rod, and the third telescopic rod are all composed of a sleeve and a telescopic part, and a clamping member is arranged between the sleeve and the telescopic part.

[0010] Preferably, the clamping member includes a groove, a protrusion and a return spring. The groove is located on the inner wall of the sleeve. The return spring is placed inside the telescopic part, and both ends of the return spring are connected with the protrusion, and the protrusion can be cooperatively connected with the groove.

[0011] Preferably, the portable construction safety protection fence further includes a bundling belt. One end of the bundling belt is connected with the rotary buckle, and the other end is detachably connected with the first lower arc-shaped sliding rod.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] Such as Figures 1 to 8As shown in the figure, the present application provides a portable construction safety protection fence, including a support assembly 1, a first enclosure assembly 2, and a second enclosure assembly 3. The support assembly 1 includes an upper arc-shaped block 13, a lower arc-shaped block 11, and a plurality of third telescopic rods 12. One end of the third telescopic rod 12 is connected to the lower arc-shaped block 11, and the other end is connected to the upper arc-shaped block 13. The third telescopic rod 12 can drive the upper arc-shaped block 13 to move up and down in the vertical direction. Opposite first sliding grooves 14 and second sliding grooves 15 are provided on both the upper arc-shaped block 13 and the lower arc-shaped block 11; the first enclosure assembly 2 is arranged in the first sliding groove 14 and can slide along the extension line of the first sliding groove 14, and the first enclosure assembly 2 is in limit fit with the first sliding groove 14; the second enclosure assembly 3 is arranged in the second sliding groove 15 and can slide along the extension line of the second sliding groove 15 in a direction opposite to that of the first enclosure assembly 2, and the second enclosure assembly 3 is in limit fit with the second sliding groove 15.

[0028] Specifically, the present application includes a support assembly 1, a first enclosure assembly 2, and a second enclosure assembly 3. The support assembly 1 further includes an upper arc-shaped block 13, a lower arc-shaped block 11, and third telescopic rods 12. The upper arc-shaped block 13 and the lower arc-shaped block 11 are structures with arc-shaped contours, and adjacent first sliding grooves 14 and second sliding grooves 15 are provided on their surfaces. The cross-sectional dimensions of the first sliding groove 14 and the second sliding groove 15 are the same, and the openings of the first sliding grooves 14 on the upper arc-shaped block 13 and the lower arc-shaped block 11 are opposite. Similarly, the openings of the second sliding grooves 15 on the upper arc-shaped block 13 and the lower arc-shaped block 11 are also opposite. One end of the third telescopic rod 12 is fixedly connected to the lower arc-shaped block 11, and the other end, as a telescopic end, is connected to the upper arc-shaped block 13. The third telescopic rod 12 can be extended or shortened, thereby driving the upper arc-shaped block 13 to move up and down in the vertical direction.

[0029] The first enclosure assembly 2 is located between the upper and lower first sliding grooves 14, and the first sliding groove 14 is a track for the first enclosure assembly 2 to slide. The first enclosure assembly 2 can slide along the extension line of the first sliding groove 14, and a limiting structure is used to ensure that the first enclosure assembly 2 moves stably in the first sliding groove 14 and will not fall off from the first sliding groove 14.

[0030] The second enclosure assembly 3 is located between the upper and lower second sliding grooves 15. The second sliding groove 15 is a track for the second enclosure assembly 3 to slide and can slide along the extension line of the second sliding groove 15 in a direction opposite to that of the first enclosure assembly 2. Similarly, a limiting structure is used to ensure that the second enclosure assembly 3 moves stably in the second sliding groove 15 and will not fall off from the second sliding groove 15.

[0031] When the first enclosure component 2 and the second enclosure component 3 slide and unfold and extend in the vertical direction, they, together with the upper arc-shaped block 13, the lower arc-shaped block 11 and the third telescopic rod 12, enclose a circular fence. Since the fence can be folded up, it occupies very little space when not in use, which is convenient for storage and transportation.

[0032] The operation process is as follows:

[0033] First, adjust the length of the third telescopic rod 12 to raise the position of the upper arc-shaped block 13. Subsequently, slide the first enclosure component 2 along the first chute 14 to unfold it in one direction, and at the same time slide the second enclosure component 3 along the second chute 15 to unfold it in the direction opposite to that of the first enclosure component 2. When the first enclosure component 2 and the second enclosure component 3 are fully unfolded, the entire fence will form a circle. During this process, the first enclosure component 2, the second enclosure component 3 and the upper arc-shaped block 13 rise to the set position together. Then, confirm that all components can be firmly fixed without falling off. After use, perform the above operations in reverse. First, retract the first enclosure component 2 into the first chute 14, retract the second enclosure component 3 into the second chute 15, and then contract the third telescopic rod 12 to lower the upper arc-shaped block 13 to the lowest position.

[0034] The above technical solution adopted by the portable construction safety protection fence provided by this application can achieve the following beneficial effects:

[0035] This application adopts an integrated design, and is provided with an upper arc-shaped block 13, a lower arc-shaped block 11, a number of third telescopic rods 12, a first enclosure component 2 and a second enclosure component 3. At the same time, a first chute 14 and a second chute 15 are opened on both the upper arc-shaped block 13 and the lower arc-shaped block 11. The first enclosure component 2 and the second enclosure component 3 can be unfolded along the extension lines of the first chute 14 and the second chute 15 respectively, and finally form a complete circular fence, effectively solving the problem that the traditional folding fence can only be in a straight line form and can only effectively enclose a single side of the construction site. When not in use, the third telescopic rod 12 is in a contracted state, and the first enclosure component 2 and the second enclosure component 3 are also retracted into the first chute 14 and the second chute 15, greatly saving storage space. The fence designed in this application is small in size and light in weight, convenient for storage and transportation in the storage state, also reduces the purchase and maintenance costs, reduces the overall project budget, shortens the handling and installation time, and saves labor.

[0036] In one embodiment, the first enclosure assembly 2 includes a first upper arc-shaped slide bar 23, a first lower arc-shaped slide bar 21, and a plurality of first telescopic rods 22. The first upper arc-shaped slide bar 23 and the first lower arc-shaped slide bar 21 are respectively disposed in the first chute 14 formed in the upper arc-shaped block 13 and the lower arc-shaped block 11, and the first upper arc-shaped slide bar 23 and the first lower arc-shaped slide bar 21 can slide along the first chute 14 simultaneously. The first upper arc-shaped slide bar 23 and the first lower arc-shaped slide bar 21 are both in limiting fit with the first chute 14. One end of the first telescopic rod 22 is connected to the first upper arc-shaped slide bar 23, and the other end is connected to the first lower arc-shaped slide bar 21. The first telescopic rod 22 can drive the first upper arc-shaped slide bar 23 to move up and down in the vertical direction.

[0037] Specifically, the first upper arc-shaped slide bar 23 has an arc-shaped contour structure and is installed in the first chute 14 of the upper arc-shaped block 13. Similarly, the first lower arc-shaped slide bar 21 also has an arc-shaped contour structure and is installed in the first chute 14 of the lower arc-shaped block 11. The first upper arc-shaped slide bar 23 and the first lower arc-shaped slide bar 21 can slide in the first chute 14, which means the entire first enclosure assembly 2 can slide in the first chutes 14 of the upper arc-shaped block 13 and the lower arc-shaped block 11. One end of the first telescopic rod 22 is connected to the first lower arc-shaped slide bar 21, and the other end, as the telescopic end, is connected to the first upper arc-shaped slide bar 23. The first telescopic rod 22 can extend or contract, thereby driving the first upper arc-shaped slide bar 23 to move up and down in the vertical direction to adjust the height of the enclosure. At the entire opening of the first chute 14, there are inward flanges, and limit blocks are respectively provided at the ends where the first upper arc-shaped slide bar 23 and the first lower arc-shaped slide bar 21 slide outwards. In this way, when the first upper arc-shaped slide bar 23 and the first lower arc-shaped slide bar 21 slide along the first chute 14, they can be prevented from sliding out of the first chute 14, and at the same time, when the first telescopic rod 22 expands in the vertical direction, the first upper arc-shaped slide bar 23 and the first lower arc-shaped slide bar 21 can be prevented from detaching from the first chute 14.

[0038] Preferably, the second enclosure assembly 3 includes a second upper arc-shaped slide bar 33, a second lower arc-shaped slide bar 31, and a plurality of second telescopic rods 32. The second upper arc-shaped slide bar 33 and the second lower arc-shaped slide bar 31 are respectively disposed in the second chute 15 on the upper arc-shaped block 13 and the lower arc-shaped block 11, and the second upper arc-shaped slide bar 33 and the second lower arc-shaped slide bar 31 can slide along the second chute 15 simultaneously. The second upper arc-shaped slide bar 33 and the second lower arc-shaped slide bar 31 are both in limiting fit with the second chute 15. One end of the second telescopic rod 32 is connected to the second upper arc-shaped slide bar 33, and the other end is connected to the second lower arc-shaped slide bar 31. The second telescopic rod 32 can drive the second upper arc-shaped slide bar 33 to move up and down in the vertical direction.

[0039] Specifically, the second upper arc-shaped slide bar 33 has an arc-shaped contour structure and is installed in the second chute 15 of the upper arc-shaped block 13. Similarly, the second lower arc-shaped slide bar 31 also has an arc-shaped contour structure and is installed in the second chute 15 of the lower arc-shaped block 11. The second upper arc-shaped slide bar 33 and the second lower arc-shaped slide bar 31 can slide within the second chute 15, which means that the entire second enclosure assembly 3 can slide within the second chutes 15 of the upper arc-shaped block 13 and the lower arc-shaped block 11. One end of the second telescopic rod 32 is connected to the second lower arc-shaped slide bar 31, and the other end, as the telescopic end, is connected to the second upper arc-shaped slide bar 33. The second telescopic rod 32 can extend or shorten, thereby driving the second upper arc-shaped slide bar 33 to move up and down in the vertical direction to adjust the height of the enclosure. Flanges are provided inwardly at the entire opening of the second chute 15, and limit blocks are respectively provided at the ends of the second upper arc-shaped slide bar 33 and the second lower arc-shaped slide bar 31 that slide outwards. In this way, when the second upper arc-shaped slide bar 33 and the second lower arc-shaped slide bar 31 slide along the second chute 15, they can be prevented from sliding out of the second chute 15, and at the same time, when the second telescopic rod 32 expands in the vertical direction, the second upper arc-shaped slide bar 33 and the second lower arc-shaped slide bar 31 can be prevented from detaching from the second chute 15.

[0040] In one embodiment, locking members 6 are provided on the first upper arc-shaped slide bar 23 and the second upper arc-shaped slide bar 33. The locking members 6 include a rotary buckle 61 hinged to the first upper arc-shaped slide bar 23 and a positioning pin 62 provided on the second upper arc-shaped slide bar 33. The positioning pin 62 can be locked with the rotary buckle 61.

[0041] Specifically, the rotary buckle 61 is installed on the first upper arc-shaped slide bar 23 and can rotate around an axis through a hinge connection. The positioning pin 62 is provided on the second upper arc-shaped slide bar 33 and is usually a protruding cylinder for cooperating with the rotary buckle 61 for locking. When the first upper arc-shaped slide bar 23 and the second upper arc-shaped slide bar 33 need to be fixed together, the rotary buckle 61 can rotate and cooperate with the positioning pin 62 to form a locked state, preventing the first upper arc-shaped slide bar 23 and the second upper arc-shaped slide bar 33 from accidentally separating during use. To unlock, simply rotate the rotary buckle 61 to disengage it from the positioning pin 62, and the first upper arc-shaped slide bar 23 and the second upper arc-shaped slide bar 33 can be easily separated. The locking members 6 ensure that the first upper arc-shaped slide bar 23 and the second upper arc-shaped slide bar 33 will not accidentally separate during use, thereby increasing the stability of the entire device during use.

[0042] In one embodiment, the first telescopic rod 22, the second telescopic rod 32, and the third telescopic rod 12 are each composed of a sleeve A and a telescopic portion B, and a clamping member 7 is provided between the sleeve A and the telescopic portion B.

[0043] Specifically, the sleeve A is the main part of the entire telescopic structure and is a hollow tubular structure. The telescopic part B is sleeved in the sleeve A and can slide within the sleeve A to achieve elongation or shortening. When the telescopic part B slides out of the sleeve A, a part remains inside the sleeve A. The clamping member 7 is installed at the connection between this part of the telescopic part B and the sleeve A, which can ensure that the telescopic part B is locked at the required position. The clamping member 7 ensures that the first telescopic rod 22, the second telescopic rod 32, and the third telescopic rod 12 remain stable during use and will not accidentally expand or contract due to external factors. To ensure durability and reliability, the sleeve A and the telescopic part B are made of high-strength materials such as aluminum alloy or stainless steel. The telescopic part B and the clamping member 7 should use precision machining techniques to ensure smooth sliding between the sleeve A and the telescopic part B, while ensuring the effective locking of the clamping member 7. The telescopic part B and the clamping member 7 should have good weather resistance to adapt to different usage environments. For example, when used outdoors, rust prevention treatment is required.

[0044] Based on the above implementation scheme, the clamping member 7 includes a groove 73, a protrusion 72, and a return spring 71. The groove 73 is located on the inner wall of the sleeve A. The return spring 71 is placed inside the telescopic part B, and both ends of the return spring 71 are connected to the protrusion 72, and the protrusion 72 can be cooperatively connected with the groove 73.

[0045] Specifically, when the telescopic part B extends relative to the sleeve A, a part will remain inside the sleeve A, thus forming a connected position after extension. At this connected position, two symmetric semi-circular grooves 73 are provided on the inner wall of the sleeve A. At this connected position, the telescopic part B is a solid structure, and a through hole for installing the return spring 71 is opened on this solid structure. The return spring 71 is placed in this through hole, and both ends are connected to the protrusion 72, enabling the protrusion 72 to slide along the through hole. In the natural state, the length of the return spring 71 is adapted to the length of the through hole to ensure that the protrusion 72 can smoothly slide into the groove 73 on the inner wall of the sleeve A. When the telescopic part B slides within the sleeve A, the protrusion 72 will be squeezed into the through hole due to the pressure on the inner wall of the sleeve A, causing the return spring 71 to be compressed. Once the protrusion 72 moves to a position aligned with the groove 73, the return spring 71 will return to its original state and expand, pushing the protrusion 72 into the groove 73 to lock the position. Additionally, the telescopic part B can be composed of two or more joint rods to meet different usage requirements.

[0046] In one implementation scheme, the portable construction safety protection fence further includes a binding band 4. One end of the binding band 4 is connected to the rotary buckle 61, and the other end is detachably connected to the first lower arc-shaped sliding rod 21.

[0047] Specifically, the binding band 4 is made of a material with high strength and certain elasticity, such as nylon, polyester fiber, etc., to adapt to different stretching requirements and maintain durability. One end of the binding band 4 is fixedly connected to the rotary buckle 61 to ensure that the binding band 4 will not accidentally fall off during use; the other end is detachably connected to the first lower arc-shaped slide bar 21 through a buckle. The buckle is arranged on the side of the first lower arc-shaped slide bar 21 and is a press type, including one or more locking mechanisms, and a reinforcing ring or hook is correspondingly arranged at the end of the binding band 4 for cooperation with the buckle. After the fence is installed, align the reinforcing ring or hook at the free end of the binding band 4 with the buckle, and gently press it down to make it enter the buckle. The locking mechanism inside the buckle will automatically bite, thus locking the binding band 4 and preventing it from fluttering in the wind. When the construction structure no longer needs the fence, untie the binding band 4, contract the first telescopic rod 22, the second telescopic rod 32 and the third telescopic rod 12, and slide the first upper arc-shaped slide bar 23, the first lower arc-shaped slide bar 21, the second upper arc-shaped slide bar 33 and the second lower arc-shaped slide bar 31 into the upper arc-shaped block 13 and the lower arc-shaped block 11 respectively. Then wind up the binding band 4 and insert it into the buckle to prevent the telescopic rods from accidentally extending.

[0048] In an embodiment, fluorescent strips 5 are provided on the outer walls of the upper arc-shaped block 13 and the lower arc-shaped block 11.

[0049] Specifically, the fluorescent strip 5 is a special material that can emit light in a dark or low-light environment after absorbing sufficient light. The fluorescent strip 5 is pasted or embedded on the outer side of the upper arc-shaped block 13 and the lower arc-shaped block 11 facing the outside, that is, the part that can be directly seen by passing vehicles or pedestrians. Under low-light conditions, the light-emitting characteristics of the fluorescent strip 5 will make the upper arc-shaped block 13 and the lower arc-shaped block 11 more conspicuous and can be clearly recognized even at night or in a dim environment. Its main purpose is to warn passing vehicles or pedestrians that there is a construction area ahead, thereby improving the safety of the construction site.

[0050] The specific operation process is as follows:

[0051] First, temporarily fix the lower arc-shaped block 11 in the construction area and untie the binding strap 4. Next, lift the upper arc-shaped block 13, which will drive the third telescopic rod 12, the first telescopic rod 22, and the second telescopic rod 32 to rise to a preset height simultaneously. At this time, during the rising of the first telescopic rod 22 and the second telescopic rod 32, the first upper arc-shaped sliding rod 23 and the second upper arc-shaped sliding rod 33 will also be promoted to rise to the same height as the upper arc-shaped block 13. After that, pull the first upper arc-shaped sliding rod 23 or the first lower arc-shaped sliding rod 21 to slide within the first chute 14 to unfold the entire first enclosure assembly 2 until it is blocked by the limit block and cannot slide. Pull the second upper arc-shaped sliding rod 33 or the second lower arc-shaped sliding rod 31 to slide within the second chute 15 to unfold the entire second enclosure assembly 3 until it is blocked by the limit block and cannot slide (regardless of the order with the first enclosure assembly 2). Use the rotary buckle 61 and the positioning pin 62 to cooperate and lock the first upper arc-shaped sliding rod 23 and the second upper arc-shaped sliding rod 33 to ensure that the entire device will not accidentally separate during use. During this process, after the first telescopic rod 22, the second telescopic rod 32, and the third telescopic rod 12 are extended, the locking between the telescopic part B and the sleeve A, and between the telescopic part B and the telescopic part B is carried out through the clamping member 7. After the fence is formed, continue to fix the binding strap 4 through the buckle.

[0052] After use, unlock the rotary buckle 61 and the positioning pin 62, and at the same time untie the binding strap 4, and slide the first upper arc-shaped sliding rod 23, the first lower arc-shaped sliding rod 21, the second upper arc-shaped sliding rod 33, and the second lower arc-shaped sliding rod 31 back into the upper arc-shaped block 13 and the lower arc-shaped block 11 respectively. Then, contract the first telescopic rod 22, the second telescopic rod 32, and the third telescopic rod 12 to lower the upper arc-shaped block 13 to the lowest position. Finally, wind the binding strap 4 around the entire device and insert the binding strap 4 into the buckle for locking.
