[0002] In the field of road engineering construction, surveying and setting out, as a basic link in construction, directly affects the quality of the project. The current scale of road construction continues to expand, and the requirements for measurement efficiency and accuracy are increasing. The traditional wire drawing and line-springing process relies on manual operation, and has technical limitations such as easy deformation of wires and uneven marking spacing, which is particularly prone to cumulative errors in long-distance construction. In the existing technology, there are three core problems: the first is the problem of discontinuity of markings caused by manual wire drawing, the second is the problem of insufficient guiding stability when laying out long distances, and the third is the defect that traditional tools cannot monitor path deviation in real time. Summary of the Invention

[0010] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: By integrating laser positioning and mechanical pay-out functions, the technical defects of traditional manual pay-out are effectively solved. The collaborative work of the transmitting unit and the receiving unit overcomes the problem of insufficient stability of the long-distance pay-out guide. The coordinated use of the laser transmitter and the receiver realizes real-time monitoring of path deviation, and the construction deviation can be corrected in time through the deviation alarm unit. The guide transmission unit adopts a combination structure of hose and support rod, which ensures the continuity of wire transmission while avoiding the problem of marking discontinuity caused by manual pulling. The rolling pay-out unit replaces the traditional line-springing process with mechanical rolling, ensuring the uniformity of marking spacing and reducing the risk of wire deformation. The paint storage unit is equipped with a flow control valve to achieve accurate quantitative output of paint, solving the problems of paint waste and unclear marking in traditional processes. The integrated design of each functional module improves the accuracy of pay-out while maintaining the portability of the equipment, adapting to the needs of complex construction environments in road projects.

DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0016] A portable line-releasing device comprises a transmitting unit arranged at an end point, which comprises a bracket and a laser transmitter arranged on the bracket.

[0017] The paint storage unit includes a paint container 1 and a flow control valve 2 connected thereto.

[0018] The guide transmission unit includes a hose 4 and a support rod 3. The main body of the hose 4 is set on the support rod 3. A placement groove is set at the bottom of the support rod 3 along the length direction. The hose 4 is fixed in the placement groove of the support rod 3 by a detachable clamp. The input end of the hose 4 is connected to the flow control valve 2.

[0019] The rolling pay-off unit includes rollers 5 rotating on both sides of the front end of the support rod 3. The output end of the hose 4 is connected to a drip nozzle 7, which is fixed at the front end of the support rod 3. The drip nozzle 7 is located at the bottom of the front end of the support rod 3 and the discharge port is opposite to the contact surface of the roller 5.

[0020] The receiving unit includes a laser receiver arranged at the front end of the support rod 3 and used in conjunction with the laser transmitter. When working, the laser transmitter and the laser receiver supported by the roller 5 are at the same height.

[0021] The deviation alarm unit includes an audible and visual alarm 6 arranged on the rod body of the support rod 3, and the audible and visual alarm 6 is control-connected to the laser receiver.

[0022] Furthermore, a paint inlet and outlet 11 and a carrying handle 12 are provided on the top of the paint container 1. The carrying handle 12 is convenient for gripping and carrying the equipment during transportation. The top inlet and outlet design enables rapid filling and cleaning of the paint, avoiding leakage problems caused by traditional side openings.

[0023] Furthermore, a handle 31 is provided at one end of the support rod 3 close to the paint container 1 .

[0024] Furthermore, the drip nozzle 7 is conical, and the conical surface guides the coating to form a stable liquid film, which helps to maintain the continuity of the discharge. The tapered structure produces a slight throttling effect, assisting the flow control valve 2 to achieve discharge uniformity.

[0025] The construction workers first fixed the bracket of the transmitting unit at the end position and started the laser transmitter, and established a reference line through laser positioning to solve the problem of insufficient stability of traditional manual wire pulling guide; then they held the handle 31 on the support rod 3 to push the equipment forward. At this time, the laser receiver monitored the path deviation in real time, and triggered the sound and light alarm 6 when it detected that the light spot deviation exceeded the set threshold of 5mm, overcoming the defect that traditional tools could not correct the deviation in real time; the paint was quantitatively output from the container with a handle 12 on the top through the flow control valve 2, and was transported to the conical drip nozzle 7 through the hose 4. The stable liquid film formed by its tapered structure and the mechanical rolling of the roller 5 not only ensured the continuity of the mark but also avoided the uneven spacing and wire deformation caused by manual wire pulling; throughout the process, the integrated design of the hose 4 and the support rod 3 of the guide transmission unit realized the continuous and stable wire laying operation.
