Description
Technical Field
[0001] This application relates to the technical field of measuring instruments, and particularly to a slope measuring instrument. Background Art
[0002] Slopes can be seen everywhere in our lives, such as highway roadbeds, river embankments, ditches, stairs, etc. The slope size of the slope body is an important control and detection index both in construction and in subsequent maintenance construction.
[0003] Currently, when measuring the slope, the slope measuring instrument is directly placed on the slope for measurement. Although this measurement is convenient, the error of this method is relatively small when measuring on a flat slope, but when measuring on a wild or uneven slope, the measurement result has a large error, thus affecting the accuracy of slope measurement. Utility Model Content
[0004] In order to reduce measurement error and improve measurement accuracy, this application provides a slope measuring instrument.
[0005] A slope measuring instrument provided by this application adopts the following technical solutions:
[0006] A slope measuring instrument includes a measurement platform. The measurement platform includes a placement table, a plurality of support rods and a plurality of connecting rods. The slope measuring instrument is placed on the placement table, and a fixing component for fixing the slope measuring instrument is provided on the placement table; both the support rods and the connecting rods are telescopic. Connecting blocks are provided at both ends of the placement table. Two ends of the connecting rod are respectively fixedly connected to the connecting block and the placement table. The support rod is fixedly connected to the connecting block and is perpendicular to the connecting rod. A leveling member for detecting the inclination angle of the placement table is provided on the placement table.
[0007] By adopting the above technical solutions, before the staff measures the slope, the staff selects two relatively flat support points on the slope and places the support rods of the measurement platform on the selected points on the slope respectively, and adjusts the length of the connecting rod according to the distance between the selected points, and adjusts the height of the support rod according to the road conditions of the slope. Subsequently, according to the leveling member, the heights of the support rods at both ends of the measurement platform are adjusted to make the placement table parallel to the slope. After setting, the staff places the slope measuring instrument on the placement table and fixes it through the fixing component, so as to more accurately measure the inclination of the slope and reduce the measurement error; if the slope is too long, the staff can select to measure in segments multiple times.
[0008] Preferably, a base is fixedly connected to the end of the support rod away from the connecting block, and a roller is installed on the base, and the roller rolls on the slope.
[0009] By adopting the above technical solution, installing rollers on the measurement platform helps the staff move the measurement platform, thereby reducing the work intensity of the staff.
[0010] Preferably, a placement groove is formed at one end of the base away from the support rod. An electric push rod is arranged in the placement groove, and one end of the electric push rod is fixedly connected to the roller.
[0011] By adopting the above technical solution, after the measurement platform is moved to a suitable position on the slope, the staff retracts the roller into the placement groove through the electric push rod. At this time, the support rod abuts against the slope. Thus, when the staff is working, the measurement platform slides on the slope under the action of the roller, affecting the measurement work and reducing the work efficiency.
[0012] Preferably, a rotation groove is formed on the side wall of the base. A support block is rotatably connected in the rotation groove. The support block is perpendicular to the support rod and abuts against the slope. An anti-slip pad is fixedly connected to the support block.
[0013] By adopting the above technical solution, after the staff retracts the roller, the staff rotates the support block so that the support block abuts against the slope. The support block not only increases the contact area with the slope, but the anti-slip pad also increases the friction between them, thereby reducing the possibility of the measurement platform sliding on the slope.
[0014] Preferably, a rotating rod rotates in the rotation groove. The support block is fixedly sleeved on the rotating rod. A pin is arranged on the side wall of the support rod. Two insertion grooves for the pin to be inserted are formed on the side wall of the support block, corresponding to the support block being perpendicular to and parallel to the support rod respectively. A spring is sleeved on the pin, and both ends of the spring are fixedly connected to the pin and the side wall of the support rod respectively.
[0015] By adopting the above technical solution, when the support block is in the rotation groove, the pin is inserted into the insertion groove, and the support block is fixed in the rotation groove. When the staff needs to activate the support block, the staff first pulls the pin away from the insertion groove. At this time, the support block rotates in the rotation under the action of gravity. The staff releases the pin, and the pin abuts against the side wall of the support block under the action of the spring. When the support block rotates to be perpendicular to the support rod, the pin aligns with one of the insertion grooves, and the pin is inserted into the insertion groove under the action of the spring, thereby fixing the position of the support block.
[0016] Preferably, the fixing component includes two clamping plates, a lead screw and a handle. An installation groove is formed on the placement table. The two clamping plates slide towards or away from each other in the installation groove. The lead screw rotates in the installation groove and is threadedly connected to the clamping plate. The handle is fixedly connected to one end of the lead screw.
[0017] By adopting the above technical solution, after the measurement platform is placed properly, the staff places the measuring instrument in the placement groove. Subsequently, the handle is rotated. The rotation of the handle drives the lead screw to rotate, and the rotation of the lead screw drives the two clamping plates to move relatively, thereby clamping and fixing the measuring instrument for measurement.
[0018] Preferably, the horizontal member is a detection plate. Two clamping blocks are fixedly connected to the side wall of the placement table. The detection plate slides in the clamping blocks. A limiting block is fixedly connected to the detection plate. The limiting block abuts against the clamping blocks. The detection plate has elasticity and abuts against the slope surface.
[0019] By adopting the above technical solution, the staff inserts the detection plate into the gap between the clamping block and the side wall of the placement table. The detection plate moves downward under the action of gravity until the bottom end abuts against the slope surface. The staff adjusts the support rods at both ends until the bottom end of the detection plate completely fits the slope surface. At this time, the placement table is parallel to the slope surface. The limiting block on the detection plate prevents the detection plate from detaching from the placement table. When the length of the detection plate is insufficient, the staff extends the telescopic plate of the detection plate.
[0020] In summary, the present application includes at least one of the following beneficial technical effects:
[0021] 1. Before the staff measures the slope, the staff selects two relatively flat support points on the slope surface, places the support rods of the measurement platform on the selected points on the slope surface respectively, and adjusts the length of the connecting rod according to the distance between the selected points. The height of the support rods is adjusted according to the road conditions of the slope surface. Subsequently, the height of the support rods at both ends of the measurement platform is adjusted according to the horizontal member to make the placement table parallel to the slope surface. After the setting is completed, the staff places the slope measuring instrument on the placement table and fixes it through the fixing component, so as to more accurately measure the inclination of the slope surface and reduce the measurement error. If the slope surface is too long, the staff can select to measure in segments multiple times;
[0022] 2. Installing rollers on the measurement platform helps the staff move the measurement platform, thereby reducing the work intensity of the staff;
[0023] 3. After the measurement platform is moved to a suitable position on the slope surface, the staff retracts the rollers into the placement groove through the electric push rod. At this time, the support rods abut against the slope surface. Therefore, when the staff is working, the measurement platform slides on the slope surface under the action of the rollers, affecting the measurement work and reducing the work efficiency.

[0029] The following further elaborates on the present application in conjunction with the attached Figures 1-3 for a more detailed description of the present application.
[0030] An embodiment of the present application discloses a slope measuring instrument, as Figure 1 shown, which includes a measuring platform 1. The measuring platform 1 includes a placement table 2, a plurality of support rods 3 and a plurality of connecting rods 4. The placement table 2 is in a cuboid shape, and an placement groove 20 is provided on its upper end surface. The measuring instrument is placed in the placement groove 20. A fixing component 5 for fixing the slope measuring instrument is provided on the placement table 2. The connecting rods 4 and the support rods 3 are relatively perpendicular to each other and are both cylindrical in shape and have telescopic properties. The connecting rods 4 are horizontally arranged along the extension direction of the placement table 2, and the support rods 3 are perpendicular to the placement table 2. Connecting blocks 6 are provided at both ends of the placement table 2. The two ends of the connecting rod 4 are respectively fixedly welded to the opposite side walls of the connecting block 6 and the placement table 2. A leveling member for detecting the inclination angle of the placement table 2 is provided on the side wall of the placement table 2.
[0031] As Figure 2 and Figure 3As shown, the fixing component 5 includes two clamping plates 17, a lead screw 18 and a handle 19. The clamping plates 17 are arranged along the extending direction of the connecting rod 4. The two clamping plates 17 slide towards or away from each other in the placement groove 20. The lead screw 18 rotates on the inner wall of the placement groove 20 and is threadedly connected to the clamping plate 17. One end of the lead screw 18 penetrates through the side wall of the placement table 2 and is fixedly welded to the handle 19. A guide rod 25 is fixedly welded in the placement groove 20, and the two clamping plates 17 slide on the guide rod 25. The horizontal member is a detection plate 21. Two clamping blocks 23 are fixedly welded on the side wall of the placement table 2. The clamping blocks 23 are L-shaped. The detection plate 21 is slidably connected to the side wall of the clamping block 23 along a direction perpendicular to the placement table 2. At both ends of the top side wall of the detection plate 21, limiting blocks 22 are fixedly welded respectively. The lower end surface of the limiting block 22 can abut against the upper end surface of the clamping block 23. The bottom of the detection plate 21 abuts against the slope surface, and the detection plate 21 has elasticity. A base 7 is fixedly welded to the bottom end of the support rod 3. The base 7 is rectangular. The base 7 is provided with a placement groove 10 in the vertical direction. An electric push rod 9 is arranged in the placement groove 10. One end of the electric push rod 9 is fixedly welded to the inner wall of the placement groove 10, and the other end is provided with a roller 8. The roller 8 rolls on the slope surface. Installing the roller 8 helps the staff to move the measuring platform 1, thereby reducing the working intensity of the staff.
[0032] As Figure 3 shown, a rotating groove 11 is opened in the side wall of the base 7 in the vertical direction. A rotating rod 13 rotates in the rotating groove 11. A support block 12 is fixedly sleeved on the rotating rod 13. The support block 12 rotates to be perpendicular to the support rod 3 and fits on the slope surface. An anti-slip pad 14 is fixedly connected to the support block 12. A pin 15 is arranged on the side wall of the support rod 3. The pin 15 is vertically inserted into the side wall of the base 7. Two insertion slots 24 for the pin 15 to be inserted are opened on the side wall of the support block 12. The pin 15 is inserted into the two insertion slots 24 corresponding to the state where the support block 12 is perpendicular to the support rod 3 and the state where the support block 12 is parallel to the support rod 3 respectively. A spring is sleeved on the pin 15. The two ends of the spring are fixedly welded to the pin 15 and the side wall of the support rod 3 respectively.
[0033] As Figure 1 and Figure 2As shown, before the staff measures the slope, the staff selects two relatively flat support points on the slope surface and pushes the measuring platform 1. The length of the connecting rod 4 is adjusted according to the distance between the selected points, so that the support rods 3 at both ends of the measuring platform 1 are respectively placed on the selected points on the slope surface. Subsequently, the staff retracts the roller 8 by controlling the electric push rod 9, and the base 7 abuts against the slope surface to reduce the possibility of the measuring platform 1 sliding on the slope surface. Then, when the staff pulls the bolt 15, the bolt 15 moves away from the insertion slot 24, and the support block 12 rotates under the action of gravity. The staff releases the bolt 15, and the spring reduces the thrust of the bolt 15 on the base 7. The bolt 15 abuts against the side wall of the support block 12 under the action of the spring. When the support block 12 rotates to be perpendicular to the support rod 3, the bolt 15 aligns with one of the insertion slots 24, and the bolt 15 is inserted into the insertion slot 24 under the action of the spring, thereby fixing the position of the support block 12. Furthermore, the lower end surface of the support and the lower end surface of the base 7 are flush and both abut against the slope surface, not only increasing the contact area with the slope surface, but also the anti-slip pad 14 on the support block 12 increasing the friction therebetween, thereby reducing the possibility of the measuring platform 1 sliding on the slope surface.
[0034] As Figure 3 shown, the staff inserts the detection plate 21 between the two clamping blocks 23. The two side walls of the detection plate 21 slide on the side walls of the clamping blocks 23. The detection plate 21 moves downward under the action of gravity until its bottom end abuts against the slope surface. Subsequently, the staff adjusts the support rods 3 at both ends until the bottom end of the detection plate 21 completely fits the slope surface. At this time, the placement table 2 is parallel to the slope surface, thereby reducing the measurement error. The limiting block 22 on the detection plate 21 prevents the detection plate 21 from detaching from the placement table 2. When the length of the detection plate 21 is insufficient, the staff activates the telescopic function of the detection plate 21. Then, the staff places the measuring instrument in the placement groove 20 and rotates the handle 19. The rotation of the handle 19 drives the screw rod 18 to rotate, and the rotation of the screw rod 18 drives the two clamping plates 17 to move relatively, thereby clamping and fixing the measuring instrument for measurement, so as to more accurately measure the inclination of the slope surface and reduce the measurement error. If the slope surface is too long, the staff can select to measure in segments multiple times.
[0035] The implementation principle of the embodiments of this application is as follows: Before the staff measures the slope, the staff selects two relatively flat support points on the slope surface, places the support rods 3 of the measurement platform 1 on the selected points on the slope surface respectively, and adjusts the length of the connecting rod 4 according to the distance between the selected points. The height of the support rod 3 is adjusted according to the road conditions of the slope surface. Subsequently, according to the horizontal member, the heights of the support rods 3 at both ends of the measurement platform 1 are adjusted to make the placement table 2 parallel to the slope surface. After the setting is completed, the staff places the slope measuring instrument on the placement table 2 and fixes it through the fixing component 5, so that the inclination of the slope surface can be measured more accurately and the measurement error can be reduced. The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
