Abstract
Description
Technical Field
[0001] The present application relates to the technical field of engineering surveying and setting out, and in particular to a setting out device. Background Art
[0002] Engineering surveying, as the cornerstone of engineering construction, is of great importance. It relies on precise laying-out devices to accurately map every detail on the design drawings, such as the precise location of the building, detailed dimensions, and strict elevations, to the actual construction site through meticulous measurement and laying-out technology, and convert it into tangible physical coordinates and dimensions. The application of this technology is not only the guardian of engineering accuracy, but also the cornerstone of dual quality and safety assurance.
[0003] At present, the widely used traditional pay-off device is composed of a stable frame, a flexible winding roller and a convenient rotating handle. When in use, the winding roller is fixed by the frame support. The winding roller serves as the winding and releasing structure of the measuring line. Then, the surveyor pulls one end of the measuring line to the other end of the pay-off to complete the pay-off for measurement. When taking up the line, the surveyor rotates the winding roller by turning the handle to achieve the winding operation. Although its operation mode is intuitive, its limitations are gradually exposed in practice. When the measuring line is slowly released from the winding roller, if there is a lack of orderly guidance and control, the measuring line often presents a disordered and scattered state, which not only increases the complexity of measurement, but also affects the efficiency and accuracy of the operation. In the winding stage, although the reverse rotation of the winding roller can realize the recovery of the measuring line, the long-term concentrated winding in one area can easily cause the measuring line to be entangled and knotted, which lays a hidden danger for subsequent reuse and may even affect the progress and quality of the entire project.

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.
[0024] Example:
[0025] See also Figure 1 , Figure 2 A wire-releasing device includes a base 1, which serves as a supporting base for the entire wire-releasing device and is made of a sturdy and durable material to ensure the stability of the wire-releasing device during operation. The surface of the base 1 is designed to be a flat mounting surface so that the wire-releasing machine 2 can be stably welded thereon.
[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A wire-releasing device comprises a wire-releasing machine 2 welded on the surface of a base 1, the wire-releasing machine 2 comprises a support frame 21, a traction mechanism 22, a retracting mechanism 23 and two bearings 24, the support frame 21 comprises a back plate 211, two side plates 212, two connecting plates 213 and a supporting rod 214; the traction mechanism 22 comprises a fixed seat 221, a driving motor 222, a rotating rod 223, a limit block I 224, a guide rod 225, a sliding groove I 226, a traction hole 227, a limit block II 228, a cross plate 229, a sliding groove II 2291 and a cross bar 2292; the retracting mechanism 23 comprises a cylinder 231, two discs 232 and a servo motor 233; a notch 3 is provided at the top of the connecting plate 213, and two threaded holes are provided at the bottom of the notch 3.
[0027] Among them, the support frame 21 is welded with a steel structure and has sufficient strength and rigidity to support the weight of the entire wire-laying machine 2 and various forces generated during the wire-laying process. The bottom end of the support frame 21 is welded and fixed to the surface of the base 1 to ensure the stability of the overall structure. Welding interfaces are reserved on the edges of both sides of the back plate 211 for integral welding with the side plates 212. The side plates 212 are also made of high-strength steel plates, and their design needs to take into account the support for the retracting mechanism 23 and the installation position of the bearing 24. The other side of the side plate 212 is welded to the connecting plate 213 to form the side frame of the support frame 21. The design of the connecting plate 213 needs to meet the installation requirements of the support rod 214, and corresponding welding interfaces and fixing holes are reserved. At the same time, the connecting plate 213 also plays a role in strengthening the overall structural strength of the support frame 21. The two ends of the support rod 214 are welded to the opposite surfaces of the two connecting plates 213. The number and positions of the support rods 214 need to be reasonably designed according to the overall size and load-bearing requirements of the support frame 21 to ensure the stability of the support frame 21 .
[0028] Among them, the traction mechanism 22 is welded to one side of the top of the support frame 21, and is a component that guides the retracting mechanism 23 to perform the wire laying or wire taking-up operation. The fixed seat 221 serves as the support base of the traction mechanism 22, and the bottom end of the fixed seat 221 is welded and fixed to the surface of the support rod 214 to ensure the stability of the entire traction mechanism 22. The fixed seat 221 is designed with a mounting hole inside to facilitate the passage of the output end of the drive motor 222. The drive motor 222 is fixed to the outer end of the fixed seat 221 and is the power source of the traction mechanism 22. The output end of the drive motor 222 is fixedly connected to one end of the rotating rod 223 through the mounting hole inside the fixed seat 221 to realize the conversion of electric energy and the transmission of power. The rotating rod 223 serves as the main transmission component of the traction mechanism 22. One end of the rotating rod 223 is fixedly connected to the output end of the drive motor 222, and the other end is hinged to the outer end of the limit block I 224. Driven by the drive motor 222, the rotating rod 223 can rotate around its axis. The limit block I 224 is hinged to the rotating rod 223, and its inner end is slidably connected to the inside of the sliding groove I 226 on the guide rod 225. The design of the limit block I 224 limits the rotation range of the rotating rod 223, ensuring that the traction mechanism 22 can move according to the predetermined trajectory. The outer wall of the guide rod 225 is provided with a sliding groove I 226 and a traction hole 227, and a limit block II 228 is welded. The guide rod 225 plays a guiding and supporting role in the traction mechanism 22, and the rotational movement of the rotating rod 223 is transmitted to the cross plate 229 through the cooperation of the sliding groove I 226 and the limit block I 224. The limit block II 228 is welded to the guide rod 225, and its outer end is slidably connected to the inside of the sliding groove II 2291 on the cross plate 229. The limit block II 228 and the limit block I 224 work together to ensure the stability and accuracy of the traction mechanism 22 during the movement. The outer wall of the horizontal plate 229 is provided with a sliding groove II 2291, and the bottom end is welded to the surface of the horizontal bar 2292. The horizontal plate 229 realizes synchronous movement with the guide rod 225 through the cooperation of the sliding groove II 2291 and the limit block II 228. The two ends of the surface of the horizontal bar 2292 can be respectively inserted into the two notches 3, and are threadedly fixed by bolts and threaded holes to achieve the purpose of fixing the traction mechanism 22.
[0029] The retractable mechanism 23 is installed on the other side of the top of the support frame 21, and its two ends are fixedly connected to the inner rings of the two bearings 24 to form a stable rotation axis. The measuring line to be released is wound on the retractable mechanism 23. With the assistance of the traction mechanism 22, the retractable mechanism 23 can smoothly release or retract the line. The cylinder 231 is the main part of the retractable mechanism 23, and the two ends of the cylinder 231 are welded and fixed to the opposite surfaces of the two discs 232. The measuring line is wound on the cylinder 231, and its diameter and length are designed according to actual needs to ensure that it can accommodate a cable of sufficient length. The separated surfaces of the two discs 232, i.e., the non-welded surfaces, are tightly fitted with the inner wall of the side plate 212 to provide stable support and positioning. At the same time, the disc 232 has a connecting column for fixed connection with the inner ring of the bearing 24 to realize the rotation of the retractable mechanism 23. The servo motor 233 is the power source of the retractable mechanism 23, and the servo motor 233 is fixed to the outer wall of the side plate 212 by bolts. The output end of the servo motor 233 is fixedly connected to the inside of the connecting column on the disc 232, and the precise rotation and speed adjustment of the cylinder 231 are achieved through a precise control algorithm.
[0030] The bearing 24 is embedded in the side plate 212 to support and guide the rotational movement of the retracting and releasing mechanism 23, thereby reducing friction and improving operating efficiency.
[0031] Among them, in the design of the support frame 21, the connecting plate 213 is one of the key components, and a notch 3 is designed on the top thereof. The shape and size of the notch 3 are determined according to actual needs to ensure that the space optimization needs are met without adversely affecting the overall structural strength of the connecting plate 213. At the same time, two threaded holes are opened at the bottom of the notch 3, and the positions and sizes of these threaded holes are accurately calculated and designed to ensure that the traction mechanism 22 can be firmly fixed by bolts.
[0032] The working principle of the wire-releasing device is as follows: when releasing the wire, one end of the measuring wire wound on the cylinder 231 is held by the surveyor through the traction hole 227. When the servo motor 233 receives the control signal and starts, its output end drives the disc 232 connected to the connecting column to rotate. Since the disc 232 is welded and fixed to the cylinder 231, the cylinder 231 will also rotate clockwise, and the measuring wire will be released. At the same time, when the driving motor 222 is started, its output end drives the rotating rod 223 to rotate. The rotation of the rotating rod 223 is transmitted to the guide rod 225 through the cooperation of the limit block I 224 and the sliding groove I 226, and then drives the limit block II 228 to slide in the sliding groove II 2291, so that the guide rod 225 reciprocates along the cross plate 229 to achieve the purpose of uniform wire-releasing. When the drum 231 rotates counterclockwise during winding, the measuring line will be wound around the drum 231 to achieve winding, and with the assistance of the traction mechanism 22, the purpose of uniform winding is achieved.
[0033] When in use, it should be noted that the specific models and specifications of the drive motor 222 and the servo motor 233 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0034] The power supply and principle of the drive motor 222 and the servo motor 233 are clear to those skilled in the art and will not be described in detail here.
[0035] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
