Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for building construction, and in particular to a structure for a building construction line-laying frame. Background Technology

[0002] In building construction projects, positioning and setting out are essential tasks in the early stages of construction and are also a guarantee of construction accuracy and quality. By setting out during building construction, construction workers can strictly follow the design drawings. Therefore, the standardization of setting out directly affects the appearance quality of the building construction and is also related to the success or failure of the entire project.

[0003] For example, patent number CN212292280U discloses a wire-laying frame for building construction sites, including a base plate. First mounting seats are fixed at both ends of the top side of the base plate. The first mounting seats are concave, and a first support rod is rotatably mounted inside the first mounting seat. A support is fixed at the top of the first support rod, and a winding drum is rotatably mounted between the supports. A mounting groove is formed at the end of the base plate opposite to the first mounting seat. A movable seat is slidably mounted inside the mounting groove. An adjusting screw is installed through the middle of the movable seat. One end of the adjusting screw extends out of the mounting groove and is fitted with a handle. Second mounting seats are fixed at the top of both ends of the movable seat. The second mounting seats are concave, and a second support rod is rotatably mounted inside the second mounting seat. A support mechanism is installed between the second support rod and the winding drum. This utility model has a simple structure and is easy to adjust.

[0004] For example, patent number CN217024780U discloses a wire-laying frame for building construction, including a positioning block, support rods, connecting rods, a support plate, a turntable, a fixing tube, and a dust cover. The positioning block has several mounting slots at its bottom. One end of each support rod is rotatably installed in a mounting slot, and the support rods rotate and unfold into a planar structure flush with the bottom surface of the positioning block. A circular turntable is rotatably installed on the positioning block, and the lower end of each connecting rod is inserted into the turntable and movably connected to the positioning block. Multiple connecting rods are coaxially connected. A disc-shaped support plate is mounted on the connecting rods, and the circular turntable is rotatably installed on the support plate. The lower end of the fixing tube is inserted into the turntable and movably connected to the support plate. A dust cover is placed on the fixing tube. This utility model allows for flexible assembly of the connecting rods and support plate to meet the installation and use requirements of multiple wire bundles. It also reduces the space occupied by the wire-laying frame by rotating and folding the support rods, facilitating storage and transportation.

[0005] Regarding the above description, the applicant believes the following problems exist: Although the existing coil feeder can meet the installation and use requirements of multiple coils, its coil shaft has a fixed inner diameter and width, making it difficult to adapt to the inner diameter and width requirements of coils of different specifications. Furthermore, since only one coil shaft is provided, multiple coils must be stacked sequentially and can only be used simultaneously. Moreover, when the bottom coil is used up, all the coils above must be disassembled, making the operation cumbersome and inefficient. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a construction wire laying frame structure with adjustable inner diameter and width of coil shafts, which can meet the adaptation needs of coils of different specifications. Each coil shaft is an independent module, supporting synchronous or independent operation, which greatly improves the flexibility of operation and the scope of application.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A construction line-laying frame structure includes a base, with lockable casters fixedly connected to the four corners of the base's bottom. A mounting frame is fixedly connected to the base, with a handle at one end and a wire hole bracket threaded to the other end. Two mounting rods are staggered on the mounting frame, with rotating shafts at both ends of each rod. A fixed wire reel is fixedly connected to one end of the rotating shaft near the mounting frame, and a quick-release cover plate is fixedly connected to the middle of the rotating shaft. Triangular plates are rotatably connected to the rotating shaft near the fixed wire reel and ratchet rack, respectively. The two triangular plates are interconnected by fixed shafts at their three endpoints. Support plates are rotatably connected to the three fixed shafts, with limit plates fixedly connected to the triangular plates, and limit support rods fixedly connected to the other ends of the support plates.

[0009] In one optional embodiment, two wire hole holders are provided, and each wire hole holder has a wire hole fixedly connected to both ends.

[0010] In one optional embodiment, ratchet racks are respectively provided on the upper and lower surfaces of the outer side of the rotating shaft away from the mounting bracket, and the rotating shaft is rotatably connected to the mounting rod through bearings provided at both ends inside.

[0011] In one optional embodiment, three limiting grooves are equidistantly provided on the fixed reel.

[0012] In one optional embodiment, three limiting grooves are provided at equal intervals at the corresponding positions of the limiting groove one on the quick-release cover plate. Two symmetrical arc-shaped blocks are fixedly connected to the edge of the central through hole of the quick-release cover plate. Pawls are rotatably connected to the upper and lower ends of the gap between the two arc-shaped blocks. An installation plate is fixedly connected to the inner side of the arc-shaped blocks below the operating end of the pawl. The pawl is connected to the installation plate by a spring.

[0013] In one alternative embodiment, the limiting plate and the support plate are connected by a torsion spring, which provides a reset torque for the rotational movement.

[0014] In one alternative embodiment, the quick-release cover can be directly close to the fixed reel on the rotating shaft, and when both pawls are pressed down simultaneously, the quick-release cover can be moved away from the fixed reel.

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

[0016] 1. A fixed coil is fixedly connected to one end of the rotating shaft near the mounting bracket. A quick-release cover is fixedly connected to the middle of the rotating shaft. Triangular plates are rotatably connected to the rotating shaft near the fixed coil and the ratchet rack, respectively. The two triangular plates are interconnected by fixed shafts at their three ends. Support plates are rotatably connected to the three fixed shafts. Limit plates are fixedly connected to the triangular plates. Limit support rods are fixedly connected to the other end of the support plates. This structure enables flexible adjustment of the inner diameter of the coil shaft, alleviating the problem that traditional pay-off frames are difficult to adapt to coils with different inner diameters due to fixed shaft diameters, and expanding the application range of the equipment.

[0017] 2. Three limiting grooves are equidistantly provided on the quick-release cover plate at positions corresponding to limiting groove one. Two symmetrical arc-shaped blocks are fixedly connected to the edge of the central through hole of the quick-release cover plate. Pawls are rotatably connected to the upper and lower ends of the gap between the two arc-shaped blocks. An installation plate is fixedly connected to the inner side of the arc-shaped blocks below the operating end of the pawl. The structure in which the pawl is connected to the installation plate through a spring realizes the flexible adjustment effect of the coil shaft width and the quick installation and locking effect of the quick-release cover plate. This alleviates the problem that traditional wire feeding frames cannot adapt to coils of different widths due to the fixed installation cover, and improves the flexibility of operation and the application range of the equipment.

[0018] 3. The mounting frame has two mounting rods arranged alternately, and each mounting rod has a rotating shaft at both ends. This structure makes each coil shaft an independent module, supporting synchronous or independent operation, which greatly improves the flexibility of operation and the scope of application.

[0019] This device is based on an improvement of existing equipment, so the improvement cost is relatively low and it will not cause a large amount of existing equipment to be discarded. It ensures the processing effect while reducing the investment in improvement costs, making it suitable for large-scale production. Attached Figure Description
