Description

Technical Field

[0001] The invention relates to the field of engineering surveying and mapping, and in particular to an engineering layout and horizontal measurement device. Background Art

[0002] At present, in the entire construction cycle of a building, it is necessary to go through the stages of preliminary preparation, land leveling and processing, construction stage and final acceptance. In the preliminary preparation process at the beginning of construction, operators need to measure and explore the site to determine the location and orientation of the construction. In the process of building foundation construction, the land needs to be leveled, the foundation needs to be dug and compacted.

[0003] During the foundation construction process, the operator needs to level the foundation, measure the elevation of the ground with a level, and determine whether it meets the construction requirements after the measurement is completed. The level needs to be leveled first to ensure its line of sight when in use. Usually, the operator makes a rough adjustment by adjusting the legs of the tripod, and then adjusts the three foot screws on the level to achieve precise adjustment of the horizontal position. Another operator carries the tape measure to the required inspection location, adjusts the inclination of the tape measure to keep it vertical, and the operator at the level reads the data on the tape measure. The elevation is obtained by measuring on both sides of the level. After completing the elevation measurement, it is necessary to set the line. The ink line will be stained with toner after passing through the ink fountain. The toner is retained on the ground by stretching the line to facilitate subsequent construction operations.

[0004] With regard to the above-mentioned related technologies, the leveling process of the level requires the operator to observe the bubble in the spirit level on the level to determine whether it is horizontal, and the operator needs to determine whether the inclination angle of the scale is perpendicular to the ground by whether the cross on the level mirror is parallel to the edge of the scale indication. Leveling by visual means results in poor leveling accuracy, and unskilled operators may cause greater errors to affect the measurement results. After completing the measurement, the operator is required to tie the ink line by piling and return to the original position to lay out the line. Summary of the invention

[0005] In order to simplify the equipment leveling process, reduce the large reading error caused by the tilt of the tower scale during the horizontal elevation measurement, complete the layout and marking at the same time as the elevation measurement, and reduce the workload of the operator, the present invention provides an engineering layout and horizontal measurement device.

[0006] The present invention provides a device for measuring the level of engineering layout, which adopts the following technical solution:

[0007] A device for measuring the level of engineering line laying comprises a tripod and a tower ruler. A fixed platform is arranged on the upper side of the tripod. A leveling motor is arranged on the upper end surface of the fixed platform. The number of the leveling motors is greater than two. The leveling motor is provided with a screw. A storage platform is arranged on the upper side of the fixed platform. The storage platform is provided with a fisheye joint corresponding to the screw one by one. A connecting block is arranged in the fisheye joint. The connecting block is threadedly connected to the screw. A through hole is opened in the center of the fixed platform. A swing rod is passed through the through hole. The swing rod is provided with a spherical joint. The spherical joint rotates in the through hole. A line laying component is arranged at the lower end of the swing rod. A swing platform is arranged on the upper side of the swing rod. The swing platform is located between the fixed platform and the storage platform. A plurality of contact switches are arranged on the upper side of the swing platform. The contact switches are arranged at intervals between two adjacent leveling motors. A locking component for fixing the spherical joint is arranged on the fixed platform. A measuring component and a control screen are arranged on the upper side of the storage platform. The weight of the part below the spherical joint of the swing rod is greater than the weight above the spherical joint.

[0008] By adopting the above technical solution, since the weight of the part below the spherical joint of the swing arm is greater than the weight above the spherical joint, the swing arm will be in a vertical state when in a natural state, and the swing platform will also be in a horizontal state. The swing arm is fixed by the locking assembly, and leveling is started through the operation screen. The contact switch is triggered by multiple up and down movements of the storage platform to complete the leveling, which can effectively speed up the leveling accuracy and reduce the operating difficulty of the operator.

[0009] Optionally, the pay-off assembly includes an ink cartridge, a pay-off wheel and a toner block are provided inside the ink cartridge, the ink line is wound around the pay-off wheel, the toner block abuts against the ink line, the pay-off wheel is rotatably connected to the inner wall of the ink cartridge, the tower ruler is slidably connected to a first mounting block, and the first mounting block is connected to the ink line.

[0010] By adopting the above technical solution, when the operator drives the tower ruler to move, the first mounting block pulls the ink line out of the ink cartridge, and while the pay-off wheel rotates, the ink line rubs against the toner block. At this time, the toner block evenly applies the toner on the ink line. After completing the elevation measurement, the operator only needs to flick the ink line to leave a mark on the ground. The elevation measurement is not interfered with and the operator does not need to re-lay out the line for marking.

[0011] Optionally, an auxiliary wire wheel is provided on the storage platform, the auxiliary wire wheel is provided with an auxiliary guide line, the tower ruler is provided with a second mounting block connected to the auxiliary guide line, the second mounting block is located above the first mounting block, a connecting assembly is provided between the first mounting block and the second mounting block, and detection brackets and guide brackets are provided at the outlets of the ink line and the auxiliary guide line. The detection bracket is located on the side close to the tower ruler, and the two guide brackets are arranged in sequence in the vertical direction. The guide bracket is provided with a guide hole, and the detection bracket is provided with a detection hole. The guide hole is directly opposite to the detection hole, and a detection sleeve is provided on the inner wall of the detection hole. The distance between the first mounting block and the second mounting block is equal to the distance between the two detection sleeves, a number of supporting springs are provided between the detection sleeve and the inner wall of the detection hole, and a number of distance sensors are also provided between the detection sleeve and the inner wall of the detection hole. The fixed platform is provided with a status indicator light, and the pay-off wheel and the auxiliary wire wheel are provided with encoders. When the swing arm is parallel to the tower ruler, the auxiliary guide line and the ink line coincide with the axis of the corresponding detection hole.

[0012] By adopting the above technical solution, the encoder detects the length of the auxiliary reference line and the ink line, and multiple distance sensors simultaneously detect the degree of deviation of the detection sleeve in the detection hole. When the angles recorded by the two encoders are the same and the two inspection sleeves are both located in the center of the detection hole, it proves that the tape measure is parallel to the swing rod, which effectively realizes the detection of whether the tape measure is vertical.

[0013] Optionally, the connecting assembly includes a distance adjusting knob and a connecting rod, a connecting rod is provided on the side where the first mounting block and the second mounting block are close to each other, a rack is provided on the side where the connecting rods are close to each other, the distance adjusting knob is located between the two connecting rods, the distance adjusting knob is provided with a gear meshing with the rack, and the distance between the first mounting block and the second mounting block changes when the distance adjusting knob is rotated, the lower end of the swing arm includes an extension rod, the extension rod is slidably connected to the end of the swing arm, a scale displaying the distance between the axes of the two guide holes is provided in the length direction of the extension rod, and the swing arm is provided with a top rod for fixing the extension rod.

[0014] By adopting the above technical solution, the adjustment knob is used to adjust the distance between the first mounting block and the second mounting block. At the same time, the distance between the two is read by a tower ruler to adjust the degree to which the extension rod extends the swing rod, thereby effectively adjusting the entire length of the swing rod for different terrains to adapt to more complex terrains.

[0015] Optionally, the measuring components include a laser rangefinder and a telescope, both of which are located at the center of the storage platform, the laser rangefinder and the storage platform are arranged in parallel from top to bottom, and both of which are directly opposite to the tower ruler.

[0016] By adopting the above technical solution, after the vertical placement of the mast, the laser rangefinder and the status indicator light work simultaneously, and the operator at the mast can read the position where the laser rangefinder hits the mast, and the operator can also read the reading on the mast by observing the telescope. The laser rangefinder can effectively and quickly detect the distance between the mast and the tripod, and when an operator performs elevation measurement, the mast can also be read.

[0017] Optionally, the swing arm is provided with a battery, which is located at the end of the extension rod away from the swing platform. The swing arm and the battery are both provided with corresponding electrode contacts. The swing arm is provided with a buckle for connecting with the battery. The inside of the swing arm is provided with a cable groove for passing cables. The storage platform is provided with an avoidance hole for passing cables. The direction of the center of gravity of the battery is the same as the axial direction of the swing arm.

[0018] By adopting the above technical solution, the battery can effectively power the equipment while effectively adjusting the center of gravity of the swing arm. It can not only power the related components above through cables, but also serve as a counterweight to improve the stability of the swing arm when it is stationary after completing the swing. It can avoid the swing arm shaking caused by tightening the locking assembly as much as possible, thereby effectively further improving the accuracy of the swing.

[0019] Optionally, the locking assembly includes a threaded rod and a locking knob, the locking knob is fixedly connected to a side of the threaded rod away from the spherical joint, a conical ejector pin is provided on a side of the threaded rod close to the spherical joint, and the spherical joint is provided with a groove adapted to the conical ejector pin.

[0020] By adopting the above technical solution, the operator rotates the locking knob to screw the threaded rod into the fixed platform, and the conical ejector pin is pushed into the groove to complete the fixation of the swing arm. When the conical ejector pin does not abut against the bottom of the groove and is located in the groove, it can effectively limit the horizontal swing of the swing arm without affecting the adjustment of the swing arm to vertical, thereby facilitating the operator to determine the direction of the device.

[0021] In summary, the present invention includes at least one of the following beneficial technical effects:

[0022] 1. Since the weight of the part below the ball joint of the swing arm is greater than the weight above the ball joint, the swing arm will be in a vertical state when in a natural state, and the swing platform will also be in a horizontal state. The swing arm is fixed by the locking assembly, and leveling is started through the operation screen. The contact switch is triggered by multiple up and down movements of the storage platform to complete the leveling, which can effectively speed up the accuracy of leveling and reduce the difficulty of operation for operators;

[0023] 2. When the operator drives the tower ruler to move, the first mounting block pulls the ink line out of the ink cartridge. While the pay-off wheel rotates, the ink line rubs against the toner block. At this time, the toner block evenly applies the toner on the ink line. After completing the elevation measurement, the operator only needs to flick the ink line to leave a mark on the ground. The elevation measurement is not interfered with and the operator does not need to re-lay out the line for marking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with all the accompanying drawings.

[0033] The embodiment of the invention discloses a device for measuring the level of engineering layout.

[0034] Reference Figures 1 to 7 A device for measuring the level of engineering layout, including a tripod 101 and a tower ruler 102. A fixed platform 1 is provided on the upper side of the tripod 101. A leveling motor 11 is provided on the upper end surface of the fixed platform 1. The number of the leveling motors 11 is greater than two. The leveling motor 11 is provided with a screw rod 111. A storage platform 3 is provided on the upper side of the fixed platform 1. The storage platform 3 is provided with a fisheye joint 31 corresponding to the screw rod 111. A connecting block 311 is provided in the fisheye joint 31. The connecting block 311 is threadedly connected to the screw rod 111. A through hole is provided in the center of the fixed platform 1. A swing rod 2 is passed through the through hole. The rod 2 is provided with a spherical joint 21, and the spherical joint 21 rotates in the through hole. A line-releasing component 4 is provided at the lower end of the swing rod 2. A swing platform 22 is provided on the upper side of the swing rod 2. The swing platform 22 is located between the fixed platform 1 and the storage platform 3. A plurality of contact switches 23 are provided on the upper side of the swing platform 22. The contact switches 23 are arranged at intervals between two adjacent leveling motors 11. The fixed platform 1 is provided with a locking component 5 for fixing the spherical joint 21. A measuring component 6 and a control panel 7 are provided on the upper side of the storage platform 3. The weight of the part below the spherical joint 21 of the swing rod 2 is greater than the weight above the spherical joint 21.

[0035] Reference Figure 1 and Figure 3 Before use, the operator unfolds the tripod 101 and completes the support. Since the weight of the part below the ball joint 21 of the swing arm 2 is greater than the weight above the ball joint 21, the swing arm 2 will be in a suspended vertical state in the natural state, and the swing platform 22 will also be in a horizontal state. The operator fixes the position of the swing arm 2 through the locking assembly 5.

[0036] Reference Figure 1 and Figure 3, after completing the fixation of the swing rod 2, the operator operates the control panel 7 to start the leveling operation. In the process of completing the invention, the applicant found that when the leveling motor 11 is single, the leveling cannot be completed, and when it is two, the leveling accuracy is low and cannot meet the accuracy requirements, so the number of leveling motors 11 should be three or more. In this embodiment, it is preferred to set three leveling motors 11 and three contact switches 23. The more leveling motors 11 and contact switches 23 are set, the higher the adjustment accuracy will be, and the corresponding device manufacturing cost and weight will also increase. The three leveling motors 11 rotate synchronously to drive the storage platform 3 to move. As the storage platform 3 approaches the swing platform 22, until a certain contact switch 23 is triggered, all the leveling motors 11 will stop rotating, and then the two leveling motors 11 adjacent to the triggered contact switch 23 will rotate in the opposite direction to move the storage platform 3 in the area upward by a short distance. After completion, the three leveling motors 11 will continue to drive the storage platform 3 to move downward, and then repeat the above process. Until the three trigger switches are triggered at the same time, it is proved that the storage platform 3 is parallel to the swing platform 22 at this time, that is, the storage platform 3 remains horizontal.

[0037] Reference Figure 1 and Figure 2 Since there are no excessive requirements for the placement of the fixed platform 1, the fixed platform 1 will not be parallel to the ground after leveling, so the leveling motor 11 will not be perpendicular to the ground after leveling is completed. In order not to affect the mutual jamming and blocking of the screw rod 111 and the storage platform 3 during the leveling process, a fisheye joint 31 is set on the storage platform 3 and a connecting block 311 is installed therein. The fisheye joint 31 can swing within a certain angle. Since three leveling motors 11 are energized and leveling is completed, the leveling bearings will continue to be energized after leveling is completed to ensure that they continue to have potential energy. Therefore, the fisheye joint 31 will be fixed and difficult to rotate after leveling is completed, thereby achieving the stability of the storage platform 3.

[0038] Reference Figure 1 , Figure 3 and Figure 5 The pay-off assembly 4 includes an ink cartridge 41, a pay-off wheel 43 and a toner block 42 are arranged inside the ink cartridge 41, an ink line 44 is wound around the pay-off wheel 43, the toner block 42 abuts against the ink line 44, the pay-off wheel 43 is rotatably connected to the inner wall of the ink cartridge 41, and the tower ruler 102 is slidably connected to the first mounting block 81, and the first mounting block 81 is connected to the ink line 44. When the operator drives the tower ruler 102 to move, the first mounting block 81 pulls the ink line 44 out of the ink cartridge 41, and while the pay-off wheel 43 rotates, the ink line 44 rubs against the toner block 42, and at this time, the toner block 42 evenly applies the toner on the ink line 44. After completing the height measurement, the operator only needs to flick the ink line 44 to leave a mark on the ground, and the height measurement is not interfered with and the operator does not need to re-lay out the line for marking.

[0039] Reference Figure 1 and Figure 7 The traditional method of detecting the tower ruler 102 is to observe with the human eye that the scale line on the telescope 61 is parallel to the scale line of the tower ruler 102, in order to quickly and intuitively determine the verticality of the tower ruler 102 and reduce the error caused by human eye observation.

[0040] Reference Figure 1 , Figure 5 and Figure 7 The storage platform 3 is provided with an auxiliary wire wheel 32, and the auxiliary wire wheel 32 is provided with an auxiliary guide line 321. The tower ruler 102 is provided with a second mounting block 82 connected to the auxiliary guide line 321, and the second mounting block 82 is located above the first mounting block 81. A connecting component 8 is provided between the first mounting block 81 and the second mounting block 82. A detection bracket 9 and a guide bracket 45 are provided at the outlet of the ink line 44 and the auxiliary guide line 321. The detection bracket 9 is located on the side close to the tower ruler 102. The two guide brackets 45 are arranged in sequence in the vertical direction. The guide bracket 45 is provided with a guide hole. The detection bracket 9 is provided with a There is a detection hole, the guide hole is opposite to the detection hole, a detection sleeve 91 is provided on the inner wall of the detection hole, the distance between the first mounting block 81 and the second mounting block 82 is equal to the distance between the two detection sleeves 91, a number of support springs 92 are provided between the detection sleeve 91 and the inner wall of the detection hole, and a number of distance sensors 93 are also provided between the detection sleeve 91 and the inner wall of the detection hole. The fixed platform 1 is provided with a status indicator light 63, and the pay-off wheel 43 and the auxiliary wire wheel 32 are both provided with an encoder 46. When the swing rod 2 is parallel to the tower ruler 102, the auxiliary alignment line 321 and the ink line 44 are both coincident with the axis of the corresponding detection hole.

[0041] Reference Figures 1 to 7 When the operator carries the measuring tape 102 away from the tripod 101, the ink line 44 and the auxiliary guide line 321 are pulled out at the same time. When the operator reaches the detection location, the measuring tape 102 stands on the ground. When the operator keeps the measuring tape 102 vertical, the status indicator 63 lights up to remind the operator that the measuring tape can be read. When the measuring tape 102 is kept vertical, the following conditions must be met.

[0042] First, the length of the released ink line 44 is equal to the length of the auxiliary guide line 321, and the number of revolutions of the pay-off wheel 43 and the auxiliary line wheel 32 should be the same, that is, the angles recorded by the two encoders 46 should be the same.

[0043] Second, since the two guide brackets 45 are arranged in sequence in the vertical direction, if the tower ruler 102 is skewed, which causes the first mounting block 81 and the second mounting block 82 to be not located in the same vertical direction, the offset directions and offset degrees of the two detection sleeves 91 in the detection hole will also be different, and the distance readings obtained by the distance sensor 93 will also be different. Therefore, it is necessary to satisfy that the two detection sleeves 91 are both located in the center of the corresponding detection hole, that is, the distance readings of the distance sensor 93 are the same.

[0044] Reference Figures 1 to 7 At this time, a rectangle is formed in a vertical plane between the guide hole of the ink line 44, the guide hole of the auxiliary guide line 321, the connection between the ink line 44 and the first mounting block 81, and the connection between the auxiliary guide line 321 and the second mounting block 82.

[0045] Reference Figure 3 and Figure 7 In order to adapt to more complex terrains, such as placing the device on slopes and steps, sometimes the device may not be used normally due to the excessive length of the swing rod 2. In order to adapt to different terrains. The connecting component 8 includes a distance adjustment knob 85 and a connecting rod 83. The first mounting block 81 and the second mounting block 82 are both provided with a connecting rod 83 on one side close to each other. The connecting rod 83 is provided with a rack 84 on one side close to each other. The distance adjustment knob 85 is located between the two connecting rods 83. The distance adjustment knob 85 is provided with a gear meshing with the rack 84. When the distance adjustment knob 85 is rotated, the distance between the first mounting block 81 and the second mounting block 82 changes. The lower end of the swing rod 2 includes an extension rod 24. The extension rod 24 is slidably connected to the end of the swing rod 2. The extension rod 24 is provided with a scale showing the distance between the axes of the two guide holes in the length direction. The swing rod 2 is provided with a top rod 242 for fixing the extension rod 24. The adjustment knob adjusts the distance between the first mounting block 81 and the second mounting block 82, and the distance between the two is read out through the scale 102, and the extension degree of the swing rod 24 is adjusted. The distance between the two guide holes can be intuitively obtained through the reading on the scale, and then the distance between the two guide holes is ensured to be equal to the distance between the first mounting block 81 and the second mounting block 82, so as to complete the detection process. The entire length of the swing rod 2 can be effectively adjusted for different terrains to adapt to more complex terrains.

[0046] Reference Figure 1 and Figure 7 In order to enable the operator to read the distance alone, and also to enable the operator to accurately measure the distance between two points when two people work together. The measuring component 6 includes a laser rangefinder 62 and a telescope 61. The laser rangefinder 62 and the telescope 61 are both located at the center of the storage platform 3. The laser rangefinder 62 and the storage platform 3 are arranged in parallel from top to bottom. The laser rangefinder 62 and the storage platform 3 are both directly opposite to the tower ruler 102. When the tower ruler 102 is placed vertically, the laser rangefinder 62 and the status indicator 63 work at the same time. The operator at the tower ruler 102 can read the position where the laser rangefinder 62 hits the tower ruler 102. The operator can also read the reading on the tower ruler 102 by observing the telescope 61. The laser rangefinder 62 can effectively and quickly detect the distance between the tower ruler 102 and the tripod 101, and when an operator performs elevation measurement, the tower ruler 102 can also be read.

[0047] Reference Figures 1 to 7 , in order to power the device and further improve the stability of the swing arm 2 after it swings and stabilizes and before the locking assembly 5 is fixed. The swing arm 2 is provided with a battery 243, and the battery 243 is located at the end of the extension rod 24 away from the swing platform 22. The swing arm 2 and the battery 243 are both provided with corresponding electrode contacts. The swing arm 2 is provided with a buckle for engaging with the battery 243. The inside of the swing arm 2 is provided with a cable groove 241 for passing the cable, and the storage platform 3 is provided with an avoidance hole for passing the cable. The center of gravity direction of the battery 243 is the same as the axial direction of the swing arm 2. While the battery 243 effectively powers the device, it can effectively adjust the center of gravity position of the swing arm 2, which can not only power the related components above through the cable, but also serve as a counterweight to improve the stability of the swing arm 2 when it is stationary after completing the swing, and can avoid the shaking of the swing arm 2 caused by tightening the locking assembly 5 as much as possible, thereby effectively further improving the accuracy of the swing.

[0048] The locking assembly 5 includes a threaded rod 51 and a locking knob 52. The locking knob 52 is fixedly connected to the side of the threaded rod 51 away from the spherical joint 21. The side of the threaded rod 51 close to the spherical joint 21 is provided with a conical ejector pin, and the spherical joint 21 is provided with a groove 211 adapted to the conical ejector pin. The operator rotates the locking knob 52 to screw the threaded rod 51 into the fixed platform 1, and the conical ejector pin is pushed into the groove 211 to complete the fixation of the swing rod 2. When the conical ejector pin does not abut against the bottom of the groove 211 and is located in the groove 211, it can effectively limit the swing of the swing rod 2 in the horizontal direction without affecting the adjustment of the swing rod 2 to the vertical direction, thereby facilitating the operator to determine the direction of the device.

[0049] The operator can adjust the pointing direction of the device by adjusting the direction of the tripod 101 .

[0050] The principle of the present invention is that the operator adjusts the swing platform 22 described in the text to a horizontal level, and then the contact switch 23 on the horizontal swing platform 22 repeatedly contacts the storage platform 3 to keep the storage platform 3 horizontal. At this time, the operator pulls out the tower ruler 102. In order to ensure that the tower ruler 102 is placed vertically, the pull-out distance of the auxiliary alignment 321 should be the same as the pull-out distance of the ink line 44, so the rotation angles recorded by the two encoders 46 should be the same. In order to make the tower ruler 102 face the telescope 61 and the laser rangefinder 62, the operator needs to adjust the distance between the first slider and the second slider to be equal to the distance between the two guide holes. The operator slides the first slider and the second slider up and down until the two detection sleeves 91 are both located in the center of the detection hole, and then the normal degree can be started.

[0051] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
