Description

Technical Field

[0001] The present invention relates to the technical field of construction protection, and more specifically, to a protection device for construction engineering. Background Art

[0002] The protective device for construction engineering construction refers to a safety facility installed at the construction site of buildings, road construction, bridge construction and other projects. Its main purpose is to protect the safety of construction personnel, equipment, pedestrians and vehicles passing by, and prevent accidents. These fences are usually made of strong materials such as steel, aluminum alloy or high-strength plastic to ensure their stability and durability. However, when using the protective device for construction engineering construction, workers often encounter problems with inconvenient disassembly and assembly. These problems are not only related to construction efficiency, but also directly affect construction safety and on-site order. Therefore, when designing protective fences, it is necessary to consider stability while also considering the convenience of disassembly and assembly.

[0003] In the prior art, a "protective safety fence for engineering construction" is disclosed, with a specific announcement number of CN219754102U, which includes a main body mechanism, a reinforcement mechanism and a convenient mechanism. The reinforcement mechanism is located at the left end of the main body mechanism, and the convenient mechanism is located below the reinforcement mechanism. The main body mechanism includes a mounting base, a safety fence 1 and a safety fence 2. The safety fence 1 is fixedly mounted on the upper end of the mounting base, and the safety fence 2 is movably mounted in front of the safety fence 1. The protective safety fence for engineering construction, through the installation of the main body mechanism, the fixing part can be rotated with the help of a movable cylinder, which is convenient for adjusting the position of the safety fence, folding the two safety fences, and transporting the safety fence. The pressing plate is convenient for clamping and fixing the fixing rod, and the two safety fences can be connected and fixed, making the connection more firm, thereby improving the convenience of using the protective safety fence for engineering construction.

[0004] Although the foldable design of this device can avoid taking up space when not in use, this device has the following disadvantages: when the protective fence needs to be transported or needs to be disassembled for recycling, this device is not easy to disassemble and subdivide, resulting in excessive volume occupied by the transportation space, affecting the convenience of transportation and use. Therefore, it is necessary to design a new type of protective device for construction engineering to solve the above problems. Summary of the invention

[0005] In view of at least one of the above technical problems, the present disclosure provides a protective device for construction engineering, aiming to solve the problem that the protective fences used for engineering construction in the prior art are inconvenient to disassemble and have great limitations in use.

[0006] According to one aspect of the present disclosure, a protective device for construction engineering is provided, comprising a pair of vertical support rods erected on the ground, a support mechanism horizontally installed between the vertical support rods for limiting position, and a protective plate clamped on the support mechanism, wherein both ends of the protective plate extend and are clamped in the vertical support rods, and the vertical support rods are also provided with a plurality of side positioning holes for cooperating with the support mechanism;

[0007] The support mechanism includes a positioning tube clamped between the vertical support rods, a support groove fixed on the positioning tube, and a support limit assembly installed at both ends of the support groove, and the support groove is adapted to the bottom block of the plate;

[0008] The inner side of the positioning tube is symmetrically provided with a positioning assembly and a pushing assembly which cooperates with the positioning assembly and is movably arranged at the bottom of the positioning tube;

[0009] The positioning assembly includes a pair of fixed shafts fixed in the positioning tube, a follower rod rotatably mounted on the fixed shaft facing outward, an active rod extending inwardly and mounted on the follower rod, and an extension plate extending outwardly and fixed on the follower rod, and a return spring 1 is further connected between the extension plate and the inner side wall of the positioning tube;

[0010] The follower rod is also provided with a rod through slot, and a positioning rod is movably clamped in the rod through slot.

[0011] Preferably, a support seat is also installed at the lower end of the vertical support rod, and an auxiliary support plate can be movably installed in the support seat, and a fixing bolt for limiting is also passed through the support seat, and a seat bottom hole corresponding to the fixing bolt is also opened at the bottom of the support seat, and plate fixing holes with sizes corresponding to the fixing bolts are also opened on the two side edges of the auxiliary support plate located on the same center line as the fixing bolt.

[0012] Preferably, the protective plate includes a plate bottom block arranged at the bottom thereof, a plate top groove arranged at the top thereof, and a plate limiting assembly installed at both ends of the plate top groove, and the plate bottom block is adapted to the plate top groove.

[0013] Preferably, the plate limiting assembly comprises a positioning block 1 which is inwardly and movably installed at both ends of the plate top groove, and a limiting block 1 which is connected to the positioning block 1 and installed outwardly, and the limiting block 1 abuts against the inner side walls of the vertical support rod.

[0014] Preferably, the pushing assembly includes a pushing block arranged between the lower part of the active rod and abutting against the active rod, a movable column connected to the bottom of the pushing block and movably passed through the bottom of the positioning tube, and a return spring 2 is also sleeved on the movable column outside the positioning tube.

[0015] Preferably, the positioning rod is movably arranged on the side wall of the positioning tube and movably arranged in the side positioning hole, and a limiting end block for limiting is also provided on the outer end of the positioning rod.

[0016] Preferably, the support limit assembly includes a limit column movably arranged on the side wall of the support groove, a positioning block connected to the inner end of the limit column, a limit block connected to the outer end of the limit column for limiting, and a return spring three mounted on the limit column inside the support groove.

[0018] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0019] 1. The device of the present application has the advantage of easy disassembly. The protective plate used is arranged between the vertical support rods in a clip-on manner and fixed on the support mechanism. When disassembly is required, it only needs to be taken down from the vertical support rods. When disassembling the protective plate, it is only necessary to manually push the movable column, and then the pushing block inside it pushes the active rod, thereby indirectly realizing the contraction of the positioning rod into the positioning tube, and the support mechanism with the limit canceled can move freely between the vertical support rods and be removed from them. The operation is simple and the construction efficiency is improved. At the same time, the transportation volume after disassembly is less, which can increase the transportable volume.

[0020] 2. The device of the present application has the advantage of wide applicability. When using the device, the protective position and height of the device can be adjusted according to the conditions of the construction site. When adjusting the position, the height of the support mechanism can be manually adjusted so that the positioning rods therein are correspondingly limited in the side positioning holes at different positions, so as to realize the adjustment of the protective position. When the area to be protected increases, a protective plate can be added to the device to increase the protective height. Since a plate limiting assembly and a support limiting assembly are respectively provided on both sides of the protective plate and the support mechanism, when a protective plate is continuously inserted downward above it, the plate limiting assembly and the support limiting assembly abut against the inner wall of the vertical support rod under the action of the plate bottom block. This design can not only avoid the gravity influence of too many protective plates on the support mechanism, but also make the connection between the vertical support rod, the protective plate and the support mechanism more firm, so as to enhance the stability of the device.

DETAILED DESCRIPTION

[0032] The embodiment of the present application solves the problem that the protective fences used for engineering construction in the prior art are inconvenient to disassemble and have great limitations in use by providing a protective device for construction engineering. In order to better understand the technical solution of the present application, the above-mentioned technical solution will be described in detail below in conjunction with the drawings in the specification and specific implementation methods.

[0033] This example discloses a protective device for construction engineering, see Figures 1 to 10Specifically, it includes a pair of vertical support rods 1 erected on the ground, a support mechanism 3 horizontally installed between the vertical support rods 1 for limiting the position, and a protective plate 2 clamped on the support mechanism 3. The two ends of the protective plate 2 are also extended and clamped in the vertical support rods 1. A plurality of side positioning holes 12 for limiting the support mechanism 3 are also provided on the vertical support rods 1. The side positioning holes 12 can be used to limit the support mechanism 3.

[0034] A support seat 11 is also installed at the lower end of the vertical support rod 1, and an auxiliary support plate 113 can be movably installed in the support seat 11. A fixing bolt 111 for limiting is also penetrated on the support seat 11, and a seat bottom hole 112 corresponding to the fixing bolt 111 is also opened at the bottom of the support seat 11.

The plate stopper assembly 23 can be used to fix the protective plate 2 on the vertical support rod 1 to improve the stability of the device.

[0036] The support mechanism 3 includes a positioning tube 31 clamped between the vertical support rods 1, a support groove 32 fixed on the positioning tube 31, and a support limit assembly 321 installed at both ends of the support groove 32. The width and depth of the support groove 32 correspond to the width and height of the bottom block 21. The support limit assembly 321 includes a limit column 3212 movably arranged on the side wall of the support groove 32, a positioning block 2 3214 connected to the inner end of the limit column 3212, a limit block 2 3211 connected to the outer end of the limit column 3212 for limiting, and a return spring 3213 sleeved on the limit column 3212 inside the support groove 32. A convex tooth 32111 for increasing friction is also arranged on the outer surface of the limit block 2 3211, and the limit block 2 3211 also abuts against the inner side walls of the vertical support rod 1. The use of the limit block 2 3211 can increase the firmness of the connection between the support mechanism 3 and the vertical support rod 1. The positioning tube 31 also includes a positioning assembly 311 rotatably fixed at both ends thereof, and a push assembly 312 cooperating with the positioning assembly 311 and movably arranged at the bottom of the positioning tube 31. The position of the support mechanism 3 can be adjusted by cooperating with the positioning assembly 311 and the push assembly 312. The positioning assembly 311 includes a pair of fixed shafts 3114 fixed in the positioning tube 31, a follower rod 3112 rotatably mounted on the fixed shaft 3114 facing outward, an active rod 3111 mounted on the follower rod 3112 extending inward, and an extension plate 3115 fixed on the follower rod 3112 extending outward, and a return spring 1 3116 is also connected between the extension plate 3115 and the inner wall of the positioning tube 31. The follower rod 3112 is also provided with a rod slot 31121, in which a positioning rod 3113 is movably mounted, the positioning rod 3113 is movably mounted on the side wall of the positioning tube 31 and is movably mounted in the side positioning hole 12, and a limiting end block 31131 for limiting is also provided on the outer end of the positioning rod 3113. The push assembly 312 includes a push block 3123 disposed between the lower side of the active rod 3111 and abutting against the active rod 3111, a movable column 3121 connected to the bottom of the push block 3123 and movably mounted on the bottom of the positioning tube 31, and a return spring 2 3122 is also sleeved on the movable column 3121 outside the positioning tube 31.

[0037] When implementing the device of the present application, the vertical support rod 1 is first erected vertically in the area to be protected, and then the protective plate 2 is horizontally clamped between the vertical support rods 1; the specific operation is that the staff pushes the movable column 3121 with their hands, and the movable column 3121 simultaneously drives the pushing block 3123 to move upward. Since the pushing block 3123 is designed with a triangular cross-section, when the pushing block 3123 moves upward, the pushing active rod 3111 rotates to both sides around the fixed axis 3114, and then drives the follower rod 3112 to rotate toward the center position in the positioning tube 31. While the follower rod 3112 rotates, it drives the positioning rod 3113 to move into the positioning tube 31 until the positioning rod 311 3 is stuck outside the positioning tube 31, and the supporting mechanism 3 can move up and down between the vertical supporting rods 1 at this time; during this period, the staff moves the supporting mechanism 3 to the specified height position according to the need of protection, and loosens the pushing movable column 3121 by hand, and the pushing block 3123 is reset under the pushing of the reset spring 2 3122, and at the same time, the positioning rod 3113 is indirectly displaced outward under the pulling of the reset spring 1 3116, and is inserted into the side positioning hole 12 at the corresponding position, so as to achieve the effect of connecting and fixing the supporting mechanism 3 with the vertical supporting rod 1; by adjusting the height of the supporting mechanism 3, the device of the present application can be applied to the construction areas of different projects, so that the device has high applicability. After fixing the supporting mechanism 3, the staff screws the fixing bolts 111, and the fixing bolts 111 pass through the plate fixing holes 1131 on the auxiliary supporting plate 113 and the seat bottom holes 112 on the supporting seat 11 and are inserted into the ground to achieve a fixing effect; moreover, when there is a strong wind in the protection area, the auxiliary supporting plate 113 can also be pulled out and fixed on the ground by the fixing bolts 111, and the staff can place heavy objects on the extended auxiliary supporting plate 113 to enhance the stability of the device; after fixing, the staff inserts the protective plate 2 into the vertical supporting rod 1 from the top and inserts it into the supporting groove 32, and while the plate bottom block 21 is inserted into the supporting groove 32, the positioning block 2 3214 is pushed to move to both sides The movement indirectly drives the limit block 2 3211 to move outward and abut against the inner wall of the vertical support rod 1 to enhance the firmness of the connection; when the protective plate 2 is continuously installed and clamped, the top groove 22 provided on the protective plate 2 can limit and fix the protective plate 2 thereon, and at the same time, the positioning block 1 232 on the top groove 22 is pushed by the bottom block 21 on it, so that the limit block 1 231 is pushed and abutted against the inner wall of the vertical support rod 1. This design can avoid the gravity of the protective plate 2 affecting the stability of the device; during the protection period, the staff can increase or reduce the stacking of the protective plates 2 according to the needs of the construction protection area, so that the device of the present application can be suitable for the protection of different engineering construction areas.When the protective fence is used up, the protective plate 2 can be directly removed from the top to the bottom along the vertical support rod 1. When the upper protective plate 2 is removed, the plate limit assembly 23 is reset under the action of its internal spring, which is convenient for the staff to continue to remove. When the last protective plate 2 is removed, the support limit assembly 321 is reset under the action of the reset spring three 3213, and the staff can push the movable column 3121 to remove the support mechanism 3. It is not only convenient to disassemble but also easy to operate.
