Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction line setting and measurement technology, and in particular to a line setting device that can easily adjust the height and level of the measuring line. Background Technology
[0002] Setting out is a crucial step in building construction. It refers to the process of marking and positioning the actual locations of various parts of a building or structure (such as walls, columns, doors, and windows) on-site using specific tools, according to the requirements of the design drawings. This process is equivalent to transferring the design content from the drawings to the actual construction site, ensuring safe and smooth construction in accordance with the approved planning requirements. Every construction project begins with setting out, and it is crucial to the success or failure of the entire project. Misalignment of buildings and failure to meet functional requirements due to incorrect setting out are common occurrences.
[0003] The existing line-laying device is just a spool with the measuring line coiled on it, supported by a bracket. During measurement, the height of the measuring line is fixed, and the levelness can only be determined by the flatness of the construction site. Therefore, it is easy to cause the measuring line to tilt or deviate, resulting in line-laying measurement errors or increased measurement errors. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a wire feeder that can not only quickly feed straight wires, but also easily adjust the height and level of the measuring wire.
[0005] To achieve the above objectives, the present invention can adopt the following technical solution:
[0006] The wire feeding device of this utility model includes a supporting base plate and a wire feeding box containing a wire feeding roller and a measuring line, which is disposed on the supporting base plate; a linear traveling wheel is disposed on the bottom surface of the supporting base plate, a pushing handle and a lifting unit are disposed on its top surface, a leveling unit is disposed on the top surface of the lifting unit, the wire feeding box is fixed on the top surface of the leveling unit, and a level is disposed on the top of the wire feeding box.
[0007] Furthermore, the top of the wire feeding box is a horizontally fastened sealing cover to facilitate opening the cover for inspection or maintenance of the wire feeding roller and measuring line inside the wire feeding box. At this time, the level should be fixed to the top surface of the sealing cover. In addition, a wire feeding nozzle through which the measuring line can pass is provided on one side wall of the wire feeding box. The wire feeding nozzle faces or is opposite to the traveling direction of the linear traveling wheel to facilitate wire feeding along the traveling direction of the linear traveling wheel. At the same time, one end of the roller shaft of the wire feeding roller should also pass through the side wall of the wire feeding box, and its protruding end is provided with an operating handle located outside the wire feeding box for easy gripping and operation.
[0008] Furthermore, the lifting unit includes a lifting push rod vertically fixed to the top surface of the supporting base plate. A horizontal support plate is fixedly connected to the lifting end of the lifting push rod, and the lifting push rod drives the horizontal support plate to move up and down. In addition, to improve the stability of the horizontal support plate's up and down movement, guide sleeves should be symmetrically arranged on both sides of the lifting push rod. The guide sleeve is composed of an outer sleeve and an inner sleeve that are appropriately fitted. The lower end of the outer sleeve is vertically fixed to the top surface of the supporting base plate, while the upper end of the inner sleeve is vertically fixed to the bottom surface of the horizontal support plate. This allows the guide sleeve to play a guiding role when the horizontal support plate moves up and down, making the horizontal support plate move up and down more smoothly.
[0009] Furthermore, the leveling unit includes a first-angle tilting slide and a second-angle tilting slide stacked on top of each other. The tilting angle adjustment directions of the first-angle tilting slide and the second-angle tilting slide are the X-axis and the Y-axis, respectively, to realize multi-angle and all-round tilting adjustment of the wire box.
[0010] The advantage of this invention is that the bottom plate with linear wheels drives the wire-laying box to move linearly, thereby quickly completing the wire laying. At the same time, the lifting and leveling units on the bottom plate and the level on the top of the wire-laying box can be used to accurately level the wire-laying box, avoiding the deviation of the measuring line caused by the tilt of the wire-laying box, ensuring the accuracy of the wire laying height and level, preventing wire laying measurement errors, and greatly reducing wire laying errors.

[0015] 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.
[0016] like Figure 1-4As shown, the wire feeding device of this utility model includes a horizontally arranged supporting base plate 1, a wire feeding box 2 on the supporting base plate 1, a rotatable wire feeding roller 3 inside the wire feeding box 2, and a measuring line 4 wound on the wire feeding roller 3. To facilitate the movement of the wire feeding box 2, four sets of linear traveling wheels 5 with the same direction should be arranged at the four corners of the bottom surface of the supporting base plate 1, and a pushing handle 6 should be arranged on the top surface of the supporting base plate 1. The pushing handle 6 has a gate-shaped structure and is composed of a pair of supporting uprights 6.1 and a horizontal cross brace 6.2 between the upper ends of the two supporting uprights 6.1. The lower ends of the two supporting uprights 6.1 are fixed to the edge of the supporting base plate 1 corresponding to the traveling direction of one side of the linear traveling wheel 5, thereby facilitating the pushing of the linear traveling wheel 5 to move in a straight line, driving the wire feeding box 2 on the supporting base plate 1 to move linearly and quickly complete the wire feeding work. In addition, a lifting unit 7 is installed on the top surface of the support base plate 1, and a leveling unit 8 is installed on the top surface of the lifting unit 7. At this time, the wire laying box 2 is fixed on the top surface of the leveling unit 8, and a level 9 is installed on the top of the wire laying box 2 to observe whether it is level. By using the lifting unit 7 and the leveling unit 8 installed on the support base plate 1, together with the level 9 installed on the top of the wire laying box 2, the wire laying box 2 can be accurately leveled, avoiding the deviation of the measuring line 4 during wire laying due to the tilt of the wire laying box 2, ensuring the accuracy of the wire laying height and levelness, preventing wire laying measurement errors, and greatly reducing wire laying errors.
[0017] Specifically, the lifting unit 7 includes a lifting push rod 7.1 vertically fixed to the top surface of the support base plate 1. A horizontal support plate 7.2 is fixedly connected to the lifting end of the lifting push rod 7.1. The lifting push rod 7.1 drives the horizontal support plate 7.2 to move up and down. In addition, to improve the stability of the horizontal support plate 7.2's up and down movement, guide sleeves 7.3 should be symmetrically arranged on both sides of the lifting push rod 7.1. The guide sleeve 7.3 is composed of an outer sleeve and an inner sleeve that are appropriately fitted. The lower end of the outer sleeve is vertically fixed to the top surface of the support base plate 1, while the upper end of the inner sleeve is vertically fixed to the bottom surface of the horizontal support plate 7.2. This allows the horizontal support plate 7.2 to move up and down more smoothly, providing a guiding function.
[0018] The leveling unit 8 includes a first-angle tilting slide 8.1 and a second-angle tilting slide 8.2 stacked on top of each other. The first-angle tilting slide 8.1 and the second-angle tilting slide 8.2 have the same structure and can both adopt commercially available products (such as the "GFG60 X-axis tilting slide" produced by Shenzhen Dingjian Automation Equipment Co., Ltd.). However, when the first-angle tilting slide 8.1 and the second-angle tilting slide 8.2 are stacked, it is necessary to ensure that the tilting angle adjustment directions of the two are X-axis and Y-axis respectively. That is, the first-angle tilting slide 8.1 is rotated 90° horizontally and fixed on the second-angle tilting slide 8.2, so that the tilting angle of the wire feeding box 2 supported on it can be easily and manually adjusted, realizing multi-angle and all-round tilting adjustment of the wire feeding box 2.
[0019] Furthermore, the top of the wire feeding box 2 is a horizontally fastened sealing cover 10. At this time, the level 9 should be fixed at the center of the top surface of the sealing cover 10. This allows for easy opening of the cover to inspect or repair the wire feeding roller 3 and measuring line 4 inside the wire feeding box 2, while ensuring that the level 9 can accurately measure the level of the entire wire feeding box 2 in real time after the sealing cover 10 is fastened. Furthermore, a wire feeding nozzle 11 is provided on one side wall of the wire feeding box 2, through which the measuring line 4 can pass. The wire feeding nozzle 11 faces or is opposite to the direction of travel of the linear travel wheel 5, facilitating wire feeding along the direction of travel of the linear travel wheel 5. Furthermore, one end of the roller shaft of the wire feeding roller 3 should also extend from the side wall of the wire feeding box 2, with an operating handle 12 located outside the wire feeding box 2 for easy gripping and operation.
[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
