Problems solved by technology

[0002] Surveying and mapping is measurement and drawing. When surveying and mapping, the staff need to use tools to mark the surveying place with a wire releaser. Most of the current wire releasers are marked with ink with pollutants, but the surveying line is usually Soaking in the ink cartridge for a long time will easily affect the performance of the surveying line, causing it to break, and the surveying line is inconvenient to retract and easy to tie. How to prevent such things from happening is what people need to solve most now. The problem

Embodiment 1

[0035] refer to Figure 1-7 , a pay-off device for surveying and mapping, comprising a box body 1, the inner wall of the box body 1 is fixedly connected with a first baffle plate 101 and a second baffle plate 102, respectively, between the first baffle plate 101 and the second baffle plate 102 The first rotating shaft 2, the second rotating shaft 3 and the reciprocating screw rod 301 are connected in rotation;

[0036] The outer wall of the first rotating shaft 2 is connected with a winding disk 201, and the outer wall of the reciprocating screw rod 301 is connected with an auxiliary winding member;

[0037] A first fixed plate 402 is also slidably connected between the second baffle plate 102 and the side wall of the box body 1, the bottom of the first fixed plate 402 is connected with a first connecting plate 403, and the outer walls of the first connecting plate 403 are respectively connected with A first pulley 404 and a second pulley 405 cooperating with each other;

Embodiment 2

[0049] refer to Figure 1-7 , a pay-off device for surveying and mapping, comprising a box body 1, the inner wall of the box body 1 is fixedly connected with a first baffle plate 101 and a second baffle plate 102, respectively, between the first baffle plate 101 and the second baffle plate 102 The first rotating shaft 2, the second rotating shaft 3 and the reciprocating screw rod 301 are connected in rotation;

[0050] The outer wall of the first rotating shaft 2 is connected with a winding disk 201, and the outer wall of the reciprocating screw rod 301 is connected with an auxiliary winding member;

[0051] A first fixed plate 402 is also slidably connected between the second baffle plate 102 and the side wall of the box body 1, the bottom of the first fixed plate 402 is connected with a first connecting plate 403, and the outer walls of the first connecting plate 403 are respectively connected with A first pulley 404 and a second pulley 405 cooperating with each other;

Embodiment 3

[0064] On the basis of embodiment 1 or embodiment 2, such as Figure 8 with Figure 9 As shown, this embodiment also includes two wearers, the two wearers are arranged at the position of the outlet hole, and the two wearers are symmetrically arranged on the upper and lower sides of the marking line, and the wearers include return springs 801, reset Rod 802 and wear-resistant roller 803. The hardness of wear-resistant roller 803 is less than or equal to the hardness of the marking line. Since the marking line is wound on the winding reel 201, it is inconvenient to replace and the replacement cost is high. When the hardness of the marking line is less than that of the wear-resistant roller When the hardness is 803, the marking line wears before the wear-resistant roller 803, which causes the marking line to be easily worn and broken, but when the hardness of the wear-resistant roller 803 is less than the hardness of the marking line, the wear-resistant roller 803 wears first, th...

Abstract

The invention discloses a wire-drawing device for surveying and mapping, which belongs to the field of surveying and mapping-laying out. A pay-off device for surveying and mapping, comprising a box body, the inner walls of the box body are respectively fixedly connected with a first baffle and a second baffle, and the first baffle and the second baffle are respectively rotatably connected with The first rotating shaft, the second rotating shaft and the reciprocating screw; the outer wall of the first rotating shaft is connected with a winding disk, and the outer wall of the reciprocating screw is connected with an auxiliary winding member; the second baffle and the box There is also a first fixing plate slidingly connected between the side walls of the body, and the outer walls of the first connecting plate are respectively rotatably connected with a first pulley and a second pulley that cooperate with each other; the outer wall of the second connecting plate is rotatably connected with a first Three pulleys; the invention is convenient to use, can prevent the surveying line from being soaked in ink for a long time, thereby affecting the energy of the surveying line, avoiding its breakage, enhancing the service life and use effect, and is convenient to retract and release without knotting.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, and in particular to a surveying and mapping line-discharging device. Background technique [0002] Surveying and mapping is measurement and drawing. When surveying and mapping, the staff need to use tools to mark the surveying place with a wire releaser. Most of the current wire releasers are marked with ink with pollutants, but the surveying line is usually Soaking in the ink cartridge for a long time will easily affect the performance of the surveying line, causing it to break, and the surveying line is inconvenient to retract and easy to tie. How to prevent such things from happening is what people need to solve most now. The problem. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and propose a kind of pay-off device for surveying and mapping. [0004] In order to achieve the above object, the prese...
