Description

Technical Field

[0001] The invention relates to the technical field of engineering measurement, in particular to a distance measuring device used for engineering measurement. Background Art

[0002] Distance measurement refers to the work of measuring the length of the line connecting two points on the ground. What usually needs to be measured is the horizontal distance, that is, the length of the projection of the line connecting the two points on a certain horizontal plane. It is one of the elements to determine the plane position of the ground point and is one of the most basic tasks in measurement work.

[0003] The Chinese patent publication number CN206563800U discloses a portable distance measuring device for engineering measurement. The portable distance measuring device for engineering measurement is provided with a storage seat, and the support rod can be rotated around the U-shaped sleeve rod through a rotating shaft. When carrying, the support rod can be rotated to be on the same horizontal line with the storage seat, so that the support rod is engaged with the card slot, and the pin and the socket are engaged to fix the support rod, thereby preventing the support rod from falling off during carrying, and ensuring that the support rod does not affect the carrying of the distance measuring device.

[0004] In engineering distance measurement, when the device measures the distance through the running wheels, since the engineering road surface usually has a lot of mud, this may cause the outer wall of the running wheels to adhere to more mud during the rolling process, thereby making the circumference of one rotation of the running wheels longer. In this case, if the distance is still calculated according to the original circumference, the error of the measured distance will increase and the measurement accuracy will be reduced.

[0005] Therefore, a distance measuring device for engineering measurement is proposed. Summary of the invention

By setting the fixed column 303, the movable frame 305 can be limited, so that the movable frame 305 can move up and down reciprocatingly more smoothly.

[0056] Specifically, Figure 1-Figure 9 As shown, a moving groove 308 is provided on the inner wall at one end of the moving frame 305, and two L-shaped bars 309 are fixedly installed on the side of the support frame 205. The two L-shaped bars 309 are rotatably installed with rotating columns 1 310 near the sides. The near ends of the two rotating columns 1 310 are fixedly connected to the side of the fixed rod 311, and a connecting shaft 313 is fixedly installed on the side of the brush 2 314.

[0063] Specifically, Figure 1-Figure 9 As shown, two fixing sleeves 405 are fixedly installed on the outer wall of the connecting shaft three 313, and L-shaped rods 406 are fixedly installed on the outer walls of the two fixing sleeves 405 respectively. Arc-shaped grooves 407 are respectively provided on the inner and outer walls of the arc plate 402, and one end of the two L-shaped rods 406 are respectively slidably connected with the inner walls of the two arc-shaped grooves 407, and a fixing frame 408 is fixedly installed on the side of the fixing rod 311. A through groove is provided on the side of the fixing frame 408, and the inner wall of the through groove is rotatably connected with the outer wall of the connecting shaft three 313, and L-shaped plates 5 are respectively fixedly installed on the sides of the two L-shaped strips 309, and multiple cleaning rods 51 are respectively fixedly installed near the sides of the two L-shaped plates 5, and the outer walls of the multiple cleaning rods 51 are slidably connected with the bristles of the brush two 314.

Through the provided L-shaped plate 5 and cleaning rod 51, when the brush 209 rotates and reciprocates in an arc, the bristles contact and slide with the multiple cleaning rods 51, so that the dust on the surface of the bristles can fall off more easily, thereby ensuring the cleanliness of the brush 209, improving the quality of the brush 209 cleaning the measuring wheel 102, and improving the measurement accuracy.

[0065] The specific solution is as follows: the pushing device moves, and when the measuring wheel 102 is measuring and rotating, it drives the rotating shaft 101 and the pulley 1 201 to rotate, the pulley 1 201 drives the pulley 2 204 and the connecting shaft 1 203 to rotate through the belt, the connecting shaft 1 203 drives the bevel gear 1 206 to rotate, the bevel gear 1 206 drives the bevel gear 207 and the connecting shaft 208 to rotate, the connecting shaft 208 drives the brush 1 209 to rotate, the brush 1 209 sweeps the loose soil on the front side of the measuring wheel 102, and the measuring wheel 102 is not easy to contact and adhere to the loose soil when measuring and rotating, so as to ensure the cleanliness of the outer wall of the measuring wheel 102, and the measuring wheel 102 is clean and tidy. 2 The circumference of one rotation is not easy to change, thereby ensuring the accuracy of measurement. At the same time, the second connecting shaft 208 drives the rotating sleeve 302 to rotate, and the rotating sleeve 302 drives the groove body 306 to rotate. The rotation of the groove body 306 drives the support column 307 and the fixed frame 304 to move back and forth up and down. When the fixed frame 304 moves back and forth up and down, it drives the second rotating column 312 to move back and forth up and down and move back and forth left and right. The second rotating column 312 drives one end of the fixed rod 311 to rotate back and forth in an arc. Similarly, the other end of the fixed rod 311 also rotates back and forth in an arc. The fixed rod 311 drives the third connecting shaft 313 and the second brush 314 to rotate back and forth in an arc. When the brush 2 314 reciprocates in an arc shape, the dirt adhering to the outer wall of the measuring wheel 102 is removed, so that the circumference of the measuring wheel 102 does not change after one rotation, and the error of the measured distance is not easily enlarged, thereby improving the measurement accuracy. When the fixed rod 311 drives the connecting shaft 3 313 to reciprocate in an arc shape, one end of the connecting shaft 3 313 drives the roller 404 to reciprocate in an arc shape. When the roller 404 reciprocates in an arc shape, the roller 404 rolls on the inner wall of the arc groove 1 403, and through the fixed sleeve 405, the L-shaped rod 406 and the arc groove 2 407, the roller 404 is in closer contact with the inner wall of the arc groove 1 403, and the roller 404 is in closer contact with the inner wall of the arc groove 1 403. The rotation of wheel 404 simultaneously drives connecting shaft three 313 to rotate, and connecting shaft three 313 drives brush two 314 to rotate. When brush two 314 rotates, it sweeps the dirt on the outer wall of measuring wheel 102, so that the dirt on the outer wall of measuring wheel 102 is cleared more thoroughly, and the measurement accuracy is further improved. Through the arrangement of L-shaped plate 5 and cleaning rod 51, when brush one 209 rotates and reciprocates in an arc, the bristles contact and slide with multiple cleaning rods 51, so that the dust on the surface of the bristles can fall off more easily, thereby ensuring the cleanliness of brush one 209, improving the quality of brush one 209 cleaning the measuring wheel 102, and improving the measurement accuracy.
