Description

Technical Field

[0001] This utility model relates to the field of construction safety protection technology, and in particular to a quick-folding temporary protective net. Background Technology

[0002] In bridge construction scenarios, the working environment is more complex and demanding. Bridges often have large spans, so temporary protective netting is needed as a key line of defense to ensure construction safety. It serves to warn and intercept pedestrians, preventing them from entering the construction site and causing unnecessary danger and trouble.

[0003] The temporary protective netting used in existing bridge construction can only be fixed piece by piece to the steel pipe columns, which often results in poor protective effect and is quite cumbersome to install and remove.

[0004] To address this, a quick-folding temporary protective netting is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a quick-folding temporary protective netting that can solve the problem that temporary protective netting used in bridge construction can only be fixed piece by piece to steel pipe columns, which often results in poor protective effect and cumbersome disassembly and assembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-folding temporary protective netting, comprising a fixed net frame, wherein a net frame unfolding mechanism is provided on the outer side of the fixed net frame;

[0007] The space frame stacking mechanism includes a damping hinge, a right space frame, a left space frame, and a connecting structure. The damping hinge is bolted to both sides of the fixed space frame. The rear side of the right space frame is bolted to the front side of the right damping hinge, and the front side of the left space frame is bolted to the rear side of the left damping hinge. The connecting structure is respectively located on the front side of the right space frame and the rear side of the left space frame.

[0008] Preferably, the connection structure includes a fixing plate embedded inside the left side of the right grid frame, and a sliding sleeve is fixedly connected to the left side of the fixing plate.

[0009] Preferably, a connecting rod is slidably connected inside the sliding sleeve, and a hand handle is fixedly connected to the bottom of the connecting rod.

[0010] Preferably, an installation plate is embedded inside the left side of the left grid frame, and a connecting sleeve is fixedly connected to the left side of the installation plate. The internal dimensions of the connecting sleeve are the same as the external dimensions of the connecting rod.

[0011] Preferably, the bottom of the front side of the right space frame and the bottom of the rear side of the left space frame are both provided with a fixing structure. The fixing structure includes a docking plate embedded in the front side of the bottom of the right space frame and a connecting plate embedded in the rear side of the bottom of the left space frame.

[0012] Preferably, both the connecting plate and the mating plate have slots on their tops, and a positioning cone rod is provided inside the front slot.

[0013] Preferably, the inner sides of the fixed grid frame, the right grid frame, and the left grid frame are all fixedly connected with reinforcing rods, and the reinforcing rods are in the shape of a cross.

[0014] Preferably, a fixing plate is fixedly connected to the top of the positioning cone rod, and the size of the fixing plate is larger than the size of the slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application cleverly simulates the opening and closing principle of a foldable screen phone by setting up a space frame folding mechanism and using damping hinges to connect the fixed space frame, the right space frame and the left space frame. This allows the right space frame and the left space frame to quickly and smoothly achieve folding and unfolding operations. When the bridge construction scene changes, such as transitioning from the pier construction stage to the bridge deck construction stage, there is no need to spend a lot of time disassembling the traditional fixed net. It can be easily folded and stored. This not only greatly shortens the disassembly and assembly time of the right space frame and the left space frame and improves construction efficiency, but also reduces the risk of damage to the net due to frequent disassembly and assembly, and extends its service life. At the same time, the folded net occupies very little space, which is convenient for storage and transportation, and provides convenience for construction site management.

[0017] 2. By setting up a connection structure, this application enables the two sets of right and left space frames to be connected and used in their unfolded state. This allows the continuously installed fixed space frames, right and left space frames to be tightly connected to form a solid whole, greatly improving the overall protective performance and effectively realizing the blocking and protection function. Moreover, this connection structure is easy to operate, and workers can quickly complete the connection or disconnection operation, further optimizing the construction process, assisting the space frame stacking mechanism, and comprehensively improving the practicality and efficiency of bridge construction safety protection.

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A quick-folding temporary protective netting includes a fixed net frame 1, and a net frame unfolding mechanism 2 is provided on the outside of the fixed net frame 1;

[0027] The space frame stacking mechanism 2 includes a damping hinge 201, a right space frame 202, a left space frame 203, and a connecting structure 204. The damping hinge 201 is bolted to both sides of the fixed space frame 1. The rear side of the right space frame 202 is bolted to the front side of the right damping hinge 201, and the front side of the left space frame 203 is bolted to the rear side of the left damping hinge 201. The connecting structure 204 is respectively located on the front side of the right space frame 202 and the rear side of the left space frame 203.

[0028] In this embodiment: By setting a fixed space frame 1 and a space frame folding mechanism 2, damping hinges 201 are set on both sides of the fixed space frame 1 and connected to the right space frame 202 and the left space frame 203 respectively. Due to the special damping characteristics of the damping hinges 201, the rotation amplitude and speed of the right space frame 202 and the left space frame 203 relative to the fixed space frame 1 can be precisely controlled. When it is necessary to fold up the right space frame 202 and the left space frame 203, the construction personnel can apply a little force, and the damping hinges 201 can smoothly guide the right space frame 202 and the left space frame 203 to fold towards both sides of the fixed space frame 1, just like the elegant closing of a foldable screen phone. The process is smooth and quiet, effectively avoiding collisions caused by rapid folding. Damage to components is prevented. When the right space frame 202 and left space frame 203 need to be deployed during the construction phase, the damping hinge 201 can apply force evenly, allowing the right space frame 202 and left space frame 203 to slowly and accurately deploy to the predetermined position. Then, the connecting structure 204 located in front of the right space frame 202 and behind the left space frame 203 comes into play. After the right space frame 202 and left space frame 203 are deployed in place, the connecting structure 204 behind the left space frame 203 of this group is connected to the connecting structure 204 at the front of the other right space frame 202. Together with the fixed space frame 1, they form a stable protective whole, which comprehensively improves the practicality and efficiency of bridge construction safety protection and escorts the bridge construction.

[0029] Specifically, such as Figure 4 As shown, the connection structure 204 includes a fixing plate 2041 embedded inside the left side of the right grid frame 202, and a sliding sleeve 2042 is fixedly connected to the left side of the fixing plate 2041.

[0030] Specifically, such as Figure 4 As shown, a connecting rod 2043 is slidably connected inside the sliding sleeve 2042, and a hand handle is fixedly connected to the bottom of the connecting rod 2043.

[0031] Specifically, such as Figure 4 As shown, an installation plate 2044 is embedded inside the left side of the left grid 203. A connecting sleeve 2045 is fixedly connected to the left side of the installation plate 2044. The internal dimensions of the connecting sleeve 2045 are the same as the external dimensions of the connecting rod 2043.

[0032] In this embodiment: By setting up a connecting structure 204, with the fixing plate 2041 embedded in the left side of the right space frame 202 as the basic support, the sliding sleeve 2042 of the fixed connection provides flexible guidance. When it is necessary to connect the two sets of left space frames 203 and right space frames 202, the construction personnel hold the hand handle at the bottom of the connecting rod 2043 and slide the connecting rod 2043 precisely along the inside of the sliding sleeve 2042. Thanks to the good size fit between the sliding sleeve 2042 and the connecting rod 2043, the connecting rod 2043 can be pushed in smoothly. At the same time, the connecting sleeve 2045 on the mounting plate 2044 embedded in the left side of the left space frame 203 has an internal size that precisely matches the external size of the connecting rod 2043. The connecting rod 2043 is inserted into the sleeve in an orderly manner, like a mortise and tenon joint, instantly and firmly fixing the two sets of left space frames 203 and right space frames 202, realizing rapid and stable splicing, effectively expanding the protection range, and improving the overall protection efficiency.

[0033] Specifically, such as Figure 5 As shown, a fixing structure 3 is provided at the bottom front side of the right space frame 202 and the bottom rear side of the left space frame 203. The fixing structure 3 includes a docking plate 301 embedded in the front bottom of the right space frame 202 and a connecting plate 302 embedded in the rear bottom of the left space frame 203.

[0034] Specifically, such as Figure 5 As shown, both the connecting plate 302 and the docking plate 301 have slots 303 on their tops, and a positioning cone rod 304 is provided inside the front slot 303.

[0035] In this embodiment: by setting a fixing structure 3, the docking plate 301 embedded in the front side of the bottom of the right space frame 202 and the connecting plate 302 embedded in the rear side of the bottom of the left space frame 203 correspond to each other. The slots 303 opened at the top of the two provide precise guidance for positioning. During construction, the positioning cone rod 304 is inserted into the front slot 303. The positioning cone rod 304 smoothly enters due to its own shape advantage and is firmly stuck in the top of the slot 303. Through this tight connection, the bottom of the right space frame 202 and the left space frame 203 are tightly attached, eliminating shaking and ensuring that the entire device stands stably in the complex environment of bridge construction, providing a solid guarantee for safety protection.

[0036] Specifically, such as Figure 3 As shown, the inner sides of the fixed space frame 1, the right space frame 202 and the left space frame 203 are all fixedly connected with reinforcing rods 4, which are cross-shaped.

[0037] Specifically, such as Figure 5 As shown, a fixing plate 5 is fixedly connected to the top of the positioning cone rod 304, and the size of the fixing plate 5 is larger than the size of the slot 303.

[0038] In this embodiment: By setting up reinforcing rods 4 and fixing plates 5, the reinforcing rods 4 are fixed in a cross shape to the inner side of the fixed grid frame 1, the right grid frame 202 and the left grid frame 203, which greatly improves the structural strength. When subjected to external impact, the cross-shaped reinforcing rods 4 can disperse stress from multiple directions, effectively preventing deformation and twisting of the fixed grid frame 1, the right grid frame 202 and the left grid frame 203, and ensuring the integrity of the protection. The fixing plates 5 are used in conjunction with the positioning cone rods 304. Their larger size design enhances the fixing effect of the positioning cone rods 304 in the slots 303.

[0039] Working Principle: In the use of temporary protective netting during bridge construction, firstly, the fixed grid 1 serves as the foundation of the entire protective system, stably bearing the forces from all sides. The damping hinges 201 located on both sides of the fixed grid 1, with their special damping characteristics, precisely control the rotation details of the right grid 202 and left grid 203 relative to the fixed grid 1. When retracting, the construction worker applies light force, and the damping hinges 201 smoothly guide the two to fold gracefully to both sides of the fixed grid 1, quietly, stably, and without collision. When unfolding, the force is applied evenly to ensure precise positioning. The connecting structure 204 then exerts force, and the fixed plate 2041 embedded on the left side of the right grid 202 carries the sliding sleeve 2042, providing guidance for the connecting rod 2043. When splicing the two sets of right grid 202 and left grid 203, the construction worker holds the bottom handle of the connecting rod 2043 and pushes it precisely along the sliding sleeve 2042. The sleeve 2045 is perfectly sized, and the connecting rod 2043 smoothly enters the sleeve, instantly achieving a secure splicing of the two sets of right space frame 202 and left space frame 203, quickly expanding the protective boundary. At the same time, the docking plate 301 and connecting plate 302 in the fixed structure 3 closely correspond to each other, and the slot 303 provides precise guidance for the positioning cone rod 304. During construction, the positioning cone rod 304 is smoothly inserted. Thanks to the design of the fixed plate 5 being larger than the slot 303, it is firmly locked at the top of the slot 303, allowing the bottom of the right space frame 202 and the left space frame 203 to fit seamlessly, without fear of shaking. Furthermore, the cross-shaped reinforcing rods 4 on the inner sides of the fixed space frame 1, right space frame 202 and left space frame 203 disperse the impact stress from external forces from multiple directions, effectively resisting deformation and torsion, and comprehensively ensuring the structural integrity in complex construction environments. This builds a solid safety barrier for bridge construction and comprehensively improves the practicality and efficiency of safety protection.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
