Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a lightning protection grounding bridging round steel bending device. Background Technology

[0002] With the rapid development of the construction industry, the importance of lightning protection and grounding engineering has become increasingly prominent. Round steel, as a commonly used conductor material in lightning protection and grounding systems, directly affects the effectiveness of the lightning protection and grounding. In actual construction, traditional round steel bending methods, such as manual bending after heating, are not only labor-intensive, but also difficult to ensure consistent bending angles and curvatures, leading to weak connections at the bridging points and affecting the reliability of the lightning protection and grounding system. Furthermore, they are inefficient and increase project costs. In addition, existing bending equipment on the market is either expensive and unsuitable for small-scale projects, or has limited functionality and cannot meet the diverse bending needs of lightning protection and grounding engineering.

[0003] Against this backdrop, the development of a round steel bending device that is easy to operate, low in cost, and suitable for lightning protection and grounding projects has become an urgent need in the industry. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a lightning protection grounding bridging round steel bending device to solve the problems of inconsistent bending angles and inability to adjust the bending angle.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lightning protection grounding bridging round steel bending device, characterized in that it comprises:

[0007] Base;

[0008] A rotatable pressing assembly includes an operating handle pivotally connected to the base for applying a bending force to the round steel bar to be processed placed below it;

The position of the limiting rod in the movement path of the operating handle is adjustable. It is used to control the bending angle of the round steel to be processed by controlling the downward stroke of the operating handle.

[0011] Furthermore, the rotatable pressing assembly also includes a rotating shaft and a sleeve. The rotating shaft is fixedly connected to the base, the sleeve is rotatably connected to the rotating shaft on the same axis, and the operating handle is fixedly connected to the sleeve.

[0012] Furthermore, the limiting bracket is provided with a first elongated hole distributed along the height direction, and the end of the limiting rod is provided with an external thread and passes through the first elongated hole and is fixedly connected to the limiting bracket by a fastening nut.

The fixing bracket is fixedly connected to the base, the support platform is detachably fixedly connected to the fixing bracket, and the pipe clamp is fixedly connected above the support platform.

[0014] Furthermore, a fixing bolt is fixedly connected to one side of the support platform, and the fixing bracket is provided with mounting holes that correspond to and cooperate with the positions of the fixing bolts. After the fixing bolts pass through the mounting holes, they are tightened by nuts.

[0015] Furthermore, the pipe clamp is a heavy-duty pipe clamp, and one of the separate pipe clamps of the heavy-duty pipe clamp is fixedly connected to the support platform.

[0016] Furthermore, the base is composed of two sets of parallel channel steels, and two sets of round steel fixing components are provided, with the two sets of round steel fixing components located on the outer sides of the two channel steels respectively.

[0017] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0018] 1. By setting the limit component, the downward stroke of the rotatable pressing component can be limited, thereby improving the consistency of the bending angle of round steel and preventing the operating handle from directly contacting the ground due to excessive operating force.

[0021] 4. The pipe clamp is detachably connected to the support platform and the fixed bracket, making it easy to replace different types of pipe clamps, thus making it suitable for the bending of different types of round steel.

[0022] 5. It can achieve both single-point bending (angle bending) and double-point bending (bridge bending) to meet different construction needs. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] like Figs. 1-3 As shown, this utility model provides a lightning protection grounding bridging round steel bending device, including a base, a rotatable pressing component disposed at the front end of the base, a round steel fixing component disposed at the rear end of the base, and a limiting component fixedly connected to the base and located between the rotatable pressing component and the round steel fixing component.

[0031] Specifically, the base consists of two sets of channel steels 1 distributed parallel to each other on the ground. The rotatable pressing assembly includes a rotating shaft 2, a sleeve 3, and an operating handle 4. The rotating shaft 2 is horizontally distributed along its length and its two ends are welded and fixed to the inner sides of the two channel steels 1 respectively. The sleeve 3 is sleeved on the outside of the rotating shaft 2 and can rotate coaxially along the rotating shaft 2. One end of the operating handle 4 is fixedly connected to the sleeve 3 along its length. The operating handle 4 can rotate along the rotating shaft 2 through the sleeve 3, thereby pressing down the round steel 14 fixed on the fixed round steel assembly through the operating handle 4.

[0032] The limiting assembly includes two sets of limiting brackets 5 and one set of limiting rods 7. The limiting brackets 5 are angle steel, one side plate of which is welded and fixed to the outer side of the channel steel 1 and is provided with a first elongated hole 6 distributed along the height direction. The length of the limiting rod 7 is horizontally distributed along the left and right directions, and both ends of the length direction are provided with external threads. The outer end of the limiting rod 7 passes through the first elongated hole 7 and can slide up and down along the first elongated hole 7 to adjust the position of the limiting rod 7 in the height direction. After adjustment, it is fixed by the first fastening nut 8. By adjusting the height of the limiting rod 7, the downward pressing height of the operating handle 4 can be limited, thereby realizing the processing of round steel 14 at different bending angles.

[0033] Two sets of round steel fixing components are provided, located on the outside of the two sets of channel steel 1 respectively. Each set of round steel fixing components consists of a fixing bracket 9, a support platform 10 and a pipe clamp 11. The fixing bracket 9 includes two sets of angle steel, which are spaced apart and welded to the outer side of the channel steel 1. The angle steel has a mounting hole on one side plate. The support platform 10 has a set of fixing bolts 12 threaded on both the front and rear sides. The end of the first fixing bolt 12 away from the support platform passes through the mounting hole on the angle steel and is fixed by the second fastening nut 13, thereby fixing the support platform 10 to the fixing bracket 9. The pipe clamp 11 is a heavy-duty pipe clamp, consisting of an upper pipe clamp and a lower pipe clamp. The lower pipe clamp is welded above the support platform 10. The lower end face of the upper pipe clamp and the lower end face of the lower pipe clamp are provided with semi-circular grooves distributed in corresponding positions, and they are also provided with threaded holes distributed in corresponding positions. When the round steel 14 is placed in the pipe clamp 11 and the left and right positions are adjusted, the upper pipe clamp and the lower pipe clamp are tightened by bolts to fix the round steel 14.

[0034] Furthermore, during the processing of round steel, the round steel 14 is fixed by a set of round steel fixing components, which can achieve the following: Fig. 2 The bending operation shown in the diagram, where the round steel 14 is positioned in the left-right direction of the round steel fixing assembly, can also be adjusted. When the round steel 14 is clamped between the two sets of round steel fixing assemblies, the following can be achieved: Fig. 3 The bending operation of the "bridge bend" structure shown.
