[0001] The present invention relates to fence construction, and more particularly to a metal fence construction device. Background Art

[0002] Metal fences can be divided into zinc steel fences, aluminum alloy fences, stainless steel fences, wrought iron fences and aluminum art fences, etc. according to their materials. Their applications can be divided into dozens of types such as residential fences, community fences, villa fences, school fences, factory fences, hospital fences, municipal fences, public facilities fences, park fences and greening fences, etc. Their specific structure is generally a staggered railing structure with sharp objects on the top to deter people from climbing over.

[0003] However, sharp objects can also cause serious puncture injuries to people who climb over, which is dangerous. Therefore, fences without sharp object structures are also produced. Such fences usually increase the difficulty of climbing over in structure, so that the human body encounters obstacles when climbing to a high place, thereby creating climbing obstacles. Such fences are also mostly multi-rail structures, and the present application is conducive to the construction of such fences. Summary of the invention

[0018] A metal fence construction device, including two frames that are symmetrically arranged and extend longitudinally, the frames are used for arranging supports, the supports are used for supporting horizontal rod-shaped members, and multiple rod-shaped members are arranged in sequence from top to bottom, so as to be welded together with vertical rod-shaped members to complete the installation of the fence. The height of the supports does not need to be adjusted again after being set once. If there is a need for a fence operation with a customized size, the spacing between the upper and lower adjacent supports can be changed. The frame includes a stand 21, which is a front-to-back conductive and upper-open structure, and is in the shape of a concave character elongated in the longitudinal direction. Two round steels 22 arranged one after the other are fixedly connected to the bottom of the stand 21, and a top seat 23 is detachably fixedly connected to the upper end of the stand 21. When the top seat 23 is removed, a support connected to the round steel 22 can be added, and the top seat 23 is matched with the top clearance of the round steel 22 to increase the stability of the round steel 22;

[0019] The support includes a base 32, which is mounted on the round steel 22 and located in the stand 21 so as to be able to slide up and down only. The base 32 can be screwed into the round steel 22 by bolts to achieve positioning, but this method is more complicated to adjust its height, and the support located at a high place is not easy to adjust. Therefore, the following scheme is preferably adopted, and the following scheme will also explain how the horizontal rod-shaped member is fixed in the support:

[0020] The support device also includes: a mounting seat 41 fixedly connected to the rear part of the upper end of the base 32, the mounting seat 41 is open to the left and right and has an upper opening structure, and two mirror-symmetrical clamping components are arranged in one mounting seat 41, and the clamping components include a reset rod 42, a vertical plate 43, an inclined plate 44, a compression spring 45 and a limiter 46; Figure 5 The fixing assembly at the rear side is shown in the figure, wherein the inclined plate 44 is integrally connected to the upper end of the vertical plate 43, and the inclined plate 44 is tilted backward from bottom to top. For the convenience of description, the inner side is between the two fixing assemblies, and the direction away from the inner side is the outer side. For example, two reset rods 42 are fixedly connected to the outer side of the vertical plate 43, and the two reset rods 42 are slidably connected to the rear part of the mounting seat 41. The outer side of the reset rod 42 is fixedly connected to the limiting portion 46, and the inner side of the limiting portion 46 abuts against the outer end of the mounting seat 41. A compression spring 45 is sleeved on the reset rod 42, and the two ends of the compression spring 45 abut against the mounting seat 41 and the corresponding vertical plate 43 respectively.

[0021] The horizontal rod-shaped member is directly squeezed into two supports of the same height, specifically between two symmetrically arranged vertical plates 43, so that the horizontal rod-shaped member does not move; this solution facilitates the direct insertion of horizontal rod-shaped members of different diameters.

[0022] Preferably, the second mounting seat 41 from top to bottom is longer, specifically, its rear portion extends backward to create a spacing with the rear portions of other mounting seats 41, so that the fixing components thereon are positioned further back. The mounting seats 41 can be replaced with mounting seats 41 of different lengths for matching according to the actual needs of the curvature, so that the second horizontal rod-shaped member from top to bottom is positioned further back than the other horizontal rod-shaped members to match the vertical rod-shaped members with curvature in the grid groove. Providing a curvature on the upper portion of the vertical rod-shaped member can increase the difficulty of climbing over the guardrail, with the protrusion of the curvature facing the outside surrounded by the fence.

[0023] An electric cylinder 31 for driving the lifting of the mounting seat 41 is installed on the front side of the upper end of the mounting seat 41. The movable end of the electric cylinder 31 is arranged upward. The mounting seat 41 is slidably connected to the round steel 22. The mounting seat 41 located above between adjacent supports is fixed to the movable end of the electric cylinder 31 located below.

[0024] Further, such as Figure 2As shown, it also includes a leveling frame 11, two stands 12 respectively fixed to the left and right ends of the leveling frame 11, and two double-headed screws 13 rotatably connected to the stands 12, the left and right sides of the double-headed screws 13 have opposite threads, and an adjustment seat 14 respectively threadedly connected to the left and right sides of the double-headed screws 13, the right parts of the two double-headed screws 13 are synchronously driven by a pulley and belt assembly, one of the double-headed screws 13 is driven by a motor to rotate, and the motor is installed on the stand 12 on the left, and the two stands 21 are respectively fixed to the upper ends of the two stands 12, and starting the motor to rotate the double-headed screw 13 can change the spacing between the left and right support devices to adapt to horizontal rod-shaped members of different lengths.

[0025] The lower end of the adjustment seat 14 is rotatably connected with a wheel 15 that travels on the leveling frame 11. The bottom of the leveling frame 11 should keep the accessories above it in a horizontal state, and the upper end of the leveling frame 11 should also be horizontal.

[0026] like Figure 7 As shown, it also includes a leveling plate 51 arranged directly below the inclined plate 44. The leveling plate 51 is used to support the bottom of the vertical rod-like members to ensure that the bottoms of all vertical rod-like members are level. A connecting seat 52 is fixed to each of the left and right ends of the leveling plate 51. The connecting seat 52 on the left is slidably connected to a positioning guide rod 53, and the connecting seat 52 on the right is fixed to the movable end of the telescopic cylinder Ⅰ55. The movable end of the telescopic cylinder Ⅰ55 is set downward, and the telescopic cylinder Ⅰ55 is installed on the positioning bracket 54.

[0027] like Figure 8 As shown, it also includes a telescopic cylinder II 61 with an upwardly disposed movable end, and a telescopic cylinder III 62 fixedly connected to the upper end of the movable end of the telescopic cylinder II 61, the movable end of the telescopic cylinder III 62 is arranged backward, and a support rod 63 fixedly connected to the movable end of the telescopic cylinder III 62, the support rod 63 extends left and right, and the minimum length is equal to the maximum spacing of the support, and a plurality of guide seats 64 are slidably connected to the support rod 63, and a limit plate 65 is fixedly connected to the left and right ends of the rear end of the guide seat 64, and a pre-tightening member 66 capable of supporting the support rod 63 is threadedly connected in the middle of the rear end of the guide seat 64, and any two adjacent guide seats 64 are connected to each other. The seat 64 is used to limit the vertical rod-like member. The top of the vertical rod-like member is placed between the two guide seats 64 and clamped by the limiting plate 65. At the same time, the vertical rod-like member rests on the front end of the horizontal rod-like member, and the front end of the vertical rod-like member rests on the rear end of the support rod 63. At this point, the limiting is completed and waiting for welding can be done. The various adjustment components of the device do not need to be adjusted again after adjustment. Multiple groups of operators can cooperate with each other to work continuously. After the staff who install the rod-like members arrange all the horizontal and vertical rod-like members, the welders perform overall welding to complete the efficient operation of the assembly line.
