Description

Technical Field

[0001] The present invention relates to the technical field of spatial planning and setting out, in particular to a setting out device for national land space planning. Background Art

[0002] The Chinese invention patent with publication number CN114180410A discloses a line-laying device for land space planning and its use method. When the vehicle body moves and the rotating shaft rotates, the first sprocket rotates synchronously, and the rotation of the second sprocket is realized through chain transmission, thereby driving the line wheel to rotate between the slides to realize the retraction and release of the measuring line. When moving, the rotation of the line wheel is realized by the movement of the vehicle body, thereby automatically realizing the retraction and release of the measuring line; the Chinese invention patent with publication number CN118145420B discloses a line-laying device for land space planning. By utilizing the rolling process of the caster during line laying, the rotation of the line-laying disk is synchronously completed, and the automatic release of the measuring line is completed, so that when laying the line, it only needs to push the device for linear displacement to automatically complete the line-laying process. There is no need for traditional devices to require multiple people to cooperate in pushing the device and manually laying the line. The measuring line can follow the undulations of the road surface to accurately lay out the line to cover the protrusions and depressions of the road surface, and the entire process is still completed automatically, which can significantly improve the overall line-laying accuracy and improve the line-laying efficiency.

[0003] In the related art, the traditional line-laying method usually adopts manual operation to lay out the line, which has high labor intensity and low work efficiency. In order to improve its work efficiency, the existing line-laying device adopts a mobile method to lay out the line, and the line-laying disk is connected to the walking wheel for transmission, so that the line-laying device can form a synchronous line-laying work when walking. However, the line-laying equipment of this method cannot position the measurement after laying out the line, so that when the line is laid out in an area with strong wind, the wind can easily cause movement interference to the measurement line; and the debris on the line-laying path, such as weeds, soil blocks, etc., cannot be cleaned up, so that during the line-laying process, the measuring line is located on the debris, thereby affecting the line-laying measurement effect.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Refer to the attached Figure 1-8 A line-paying device for land space planning comprises a frame 1, the bottom of which is rotatably connected to a rotating shaft 2, both ends of the rotating shaft 2 are fixedly connected to walking wheels 3, a line-paying drum 4 is provided on the top of the frame 1, a measuring line 5 is wound around the outer surface of the line-paying drum 4, the line-paying drum 4 is connected to the rotating shaft 2 through two sets of belt groups 6, a rotating assembly 7 is provided on the top of the frame 1, and the line-paying drum 4 is rotatably connected to the top of the frame 1 through the rotating assembly 7;

[0040] A guide assembly 8 for pressing the measuring line 5 downward is provided at the bottom of the frame 1. The guide assembly 8 includes a guide wheel 81 that can be elastically extended up and down. The outer surface of the guide wheel 81 is provided with a limiting groove for limiting the measuring line 5.

[0041] The guide wheel 81 can be provided to press the measuring line 5 that is in contact with the ground after the line is laid out, thereby improving the effect of the measuring line 5 after the line is laid out and preventing the measuring line 5 from being wrinkled and suspended in the air. The limit groove is provided to position the measuring line 5 during the line laying process, thereby improving the straightness of the measuring line 5 and preventing the measuring line 5 from being bent.

[0042] A cleaning assembly 9 for cleaning debris on the measuring ground is provided on one side of the frame 1, and two positioning assemblies 10 for positioning the measuring line 5 after the line is laid out are provided on one side of the bottom of the frame 1;

[0043] By setting the cleaning component 9, the debris on the line-laying path can be cleaned to prevent the debris from affecting the line-laying effect, and by setting the positioning component 10, the measuring line 5 after the line is laid can be positioned to prevent the strong wind in the line-laying environment from interfering with the measuring line 5 and affecting the line-laying measurement effect.

[0044] Refer to the attached Figure 1 and Figure 4 The cleaning assembly 9 includes a connecting frame 91 fixed to one side of the frame 1, and an inclined conical cleaning block 92 is fixedly connected to the bottom of the connecting frame 91;

[0045] The conical cleaning block 92 is provided to clean up debris on the line-laying path, thereby improving the contact effect between the measuring line 5 and the ground. This solves the problem that the measuring line 5 is located on the debris during the line-laying process, which affects the line-laying measurement effect due to the presence of a large number of debris of different thicknesses on the line-laying path.

[0046] Refer to the attached Figure 1 and Figure 4 , the bottom of the conical cleaning block 92 is fixedly connected with an inclined slotted piece 93, and the connecting frame 91 adopts a telescopic and adjustable telescopic frame;

[0047] The slotted sheet 93 is provided to open a measuring groove on the ground, and the depth of the groove is less than or equal to one centimeter. The opening of the measuring groove not only facilitates intuitive understanding of the straightness of the laying line, but also allows for preliminary positioning of the measuring line 5 for laying out, thereby improving the smoothness of the laying line.

[0048] The connecting frame 91 adopts a telescopic and adjustable snap-on telescopic frame, which facilitates the adjustment of the height of the conical cleaning block 92 and the slotted piece 93, thereby improving the effectiveness of cleaning debris on the line-laying path.

[0049] Refer to the attached Figure 2 and Figure 3 The positioning assembly 10 includes a mounting frame 101 fixed to the bottom of the frame 1, one end of the mounting frame 101 is rotatably connected to two positioning wheels 102, and the inner side of the mounting frame 101 is provided with a positioning member for burying and positioning the measuring line 5, and the positioning member is transmission-connected to one of the positioning wheels 102;

[0050] The setting of the positioning wheel 102 is used to improve the stability of the line-laying equipment when walking and standing, thereby improving its positioning when laying out the line. The setting of the positioning piece is used to pile the soil on the ground on the measuring line 5 in an equidistant manner, which not only ensures the straightness of the measuring line 5 and improves its measurement accuracy, but also avoids the influence of force majeure in the measurement environment on the twisting and bending of the measuring line 5.

[0051] Refer to the attached Figure 2 and Figure 3 The positioning member includes a fixing frame 103 fixed to the inner side of the mounting frame 101 and a reciprocating screw 104 fixed to the side of one of the positioning wheels 102. The outer surface of the reciprocating screw 104 is transmission-connected with a reciprocating block 105. The top of the reciprocating block 105 is slidably connected to the bottom of the fixing frame 103. The bottom of the reciprocating block 105 is fixedly connected to an inclined collecting block 106.

[0052] The movement of the positioning wheel 102 on the ground can drive the reciprocating screw 104 to rotate, and the rotation of the reciprocating screw 104 can drive the reciprocating block 105 to move back and forth, and further drive the collecting block 106 to move left and right;

[0053] By moving the collecting block 106 left and right, the soil on both sides of the measuring line 5 can be gathered to the middle, and then the equidistant burial positioning work is carried out, thereby improving the stability of the measuring line 5 after the line is laid out, and preventing the air flow in the environment from interfering with the measuring line 5, causing the measuring line 5 to be distorted and affecting its measurement effect.

[0054] Example 2: Based on Example 1, the difference is that;

[0055] Refer to the attached Figure 1 and Figure 8 The guide assembly 8 includes a T-shaped plate 82 fixed to the bottom of the frame 1, and both sides of the T-shaped plate 82 are slidably connected to the L-shaped plate 83. Both sides of the top of the T-shaped plate 82 are fixedly connected to springs 84, and the top ends of the two springs 84 are respectively fixedly connected to the tops of the two L-shaped plates 83. The guide wheel 81 is rotatably connected between the bottom ends of the two L-shaped plates 83 through a rotating shaft;

[0056] The guide wheel 81 adopts two L-shaped plates 83 to be slidably connected to the T-shaped plate 82, thereby improving the smoothness of the up and down movement of the guide wheel 81. The two sets of springs 84 are provided to increase the extrusion force of the downward movement of the guide wheel 81, thereby improving the pressing effect of the guide wheel 81 on the measuring line 5 on the ground, improving the stability of the measuring line 5 on the ground, and preventing the measuring line 5 from wrinkling and bending, which affects the subsequent measurement effect.

[0057] Example 3: Based on Example 1, the difference is that;

[0058] Refer to the attached Figure 6 and Figure 7 The rotating assembly 7 includes two rotating shafts 71 rotatably connected to the top of the frame 1 through a bracket. The other ends of the two rotating shafts 71 are transmission-connected to the rotating shaft 2 through a belt group 6. The opposite ends of the two rotating shafts 71 are slidably connected to T-shaped sliding sleeves 72. The inner sides of the two T-shaped sliding sleeves 72 are fixedly connected to the limit frames 73. The inside of the pay-off drum 4 is provided with a limit opening for inserting the two limit frames 73.

[0059] The rotating shaft 71 is connected to the rotating shaft 2 through a belt group 6, so that the rotating shaft 2 can be rotated by the belt group 6 to drive the rotating shaft 71 to rotate synchronously, and then the T-shaped sliding sleeve 72 can be driven to rotate. The rotation of the T-shaped sliding sleeve 72 can drive the wire-paying drum 4 connected thereto to rotate, thereby forming a wire-paying operation;

[0060] Through the setting of the two limit frames 73, it is used to insert the limit openings at the corresponding positions, so that the T-shaped sliding sleeve 72 and the pay-off drum 4 can be rotated and locked, ensuring that when the T-shaped sliding sleeve 72 rotates, it can synchronously drive the pay-off drum 4 to rotate, forming an automatic pay-off operation;

[0061] The outer surfaces of the two T-shaped sliding sleeves 72 are rotatably connected to the sliding frames 74. The two sliding frames 74 are slidably connected to the top of the frame 1. The top of the frame 1 is provided with a driving member 75 for driving the two T-shaped sliding sleeves 72 towards or away from each other.

[0062] Through the setting of the driving member 75, it is convenient for the staff to drive the two T-shaped sliding sleeves 72 relative to or apart, and then to replace the pay-off reel 4. It has good disassembly and assembly functions, which makes it convenient for the staff to replace different models of pay-off reels 4 and measuring lines 5 according to the actual measurement and pay-off conditions, thereby improving the functionality and practicality of its pay-off device.

[0063] The driving member 75 includes a threaded rod 751 rotatably connected to the top of the frame 1 through a bracket. The outer surface of the threaded rod 751 is threadedly connected to a threaded block 752. Both sides of the threaded block 752 are hingedly connected to an inclined driving frame 753. One end of each of the two driving frames 753 is hingedly connected to a movable frame 754. One end of the two movable frames 754 is fixedly connected to the two sliding frames 74 respectively.

[0064] By manually rotating the threaded rod 751, the threaded block 752 can be driven to move left and right, which in turn can drive the two drive frames 753 to move in a fan-shaped manner. The fan-shaped movement of the two drive frames 753 can drive the two movable frames 754 to move relative to or apart from each other, and further, the two sliding frames 74 can drive the two T-shaped sliding sleeves 72 to move relative to or apart from each other.

[0065] By moving the two T-shaped sliding sleeves 72 in relative directions, the pay-off drum 4 can be locked to form the installation of the pay-off drum 4; on the contrary, by moving the two T-shaped sliding sleeves 72 away from each other, the fastening of the pay-off drum 4 can be lost, thereby facilitating the replacement of the pay-off drum 4. It has good disassembly and assembly functions, which is convenient for the staff to replace different models of pay-off drums 4 and measuring lines 5 according to the actual measurement and pay-off conditions, thereby improving the functionality and practicality of its pay-off device.
