Description

Technical Field

[0001] The utility model belongs to the technical field of slope measurement, and in particular relates to a slope measuring device for highway construction. Background Art

[0002] As we all know, the slope measuring device commonly used in highway construction is an instrument for measuring the slope, including: slope meter, laser rangefinder, total station, GNSS receiver, etc. Among them, laser rangefinder (Laser Level): Laser rangefinder is a device that uses laser technology to measure distance. In highway construction, the laser rangefinder can measure the height difference of the ground by emitting a laser beam and receiving the reflected beam, thereby determining the size of the slope.

[0003] A laser rangefinder is disclosed in a utility model patent with a patent authorization announcement number of CN206930780U. The laser rangefinder includes a support assembly and a rangefinder body. The rangefinder body is provided with a laser head capable of emitting a laser beam, and one end is rotatably mounted on the support assembly. The support assembly forms a predetermined angle with a line connecting a measurement start point and a measurement end point. The rangefinder body rotates with its connection point with the support assembly as a rotation axis. The laser rangefinder performs rangefinder of unobstructed objects when the rangefinder body rotates relative to the support assembly until the laser head is aligned with the measurement end point.

[0004] However, the existing road construction slope measurement device also has certain shortcomings. First, the existing road construction slope measurement device mostly uses manual operation to adjust the position of the laser rangefinder, which is not convenient for operators to measure.

[0005] Secondly, the existing slope measurement devices for highway construction mostly use bolts and other structures to install the laser rangefinder, and the use of bolts requires professional assembly tools, which is undoubtedly inconvenient to operate. Summary of the invention

[0006] The utility model aims to provide a slope measuring device for highway construction, which solves the problem that the existing slope measuring devices for highway construction mostly use manual operation to adjust the position of the laser rangefinder, which is inconvenient for operators to use for measurement; and solves the problem that the existing slope measuring devices for highway construction mostly use bolts and other structures to install and use the laser rangefinder, and the use of bolts requires professional assembly tools, which is inconvenient to operate.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a slope measuring device for highway construction, comprising a base, a rotating seat is fixedly connected to the right side of the upper end of the base, a motor is fixedly installed on the front side of the rotating seat, the output shaft of the motor is rotatably connected to the rotating seat, a mounting plate is fixedly sleeved on the outer side of the output shaft of the motor, the mounting plate is in contact with the rotating seat, a laser rangefinder is in contact with the left end of the mounting plate, a plug plate is fixedly connected to the right end of the laser rangefinder, the plug plate is slidably connected to the mounting plate, an end 1 is fixedly connected to the inside of the mounting plate, an insertion rod is slidably connected to the inside of the mounting plate, the insertion rod is slidably connected to the insertion plate, and an end 2 is fixedly connected to the right side of the insertion rod.

[0008] The principle of the utility model is: by pushing the laser rangefinder to contact with the mounting plate, the plug-in plate is inserted into the mounting plate. In this process, when the oblique end of the plug-in plate contacts the round end of the plug-in rod, the plug-in rod drives the second end to move under the extrusion of the force. Under the action of the first end, the tension spring is deformed, and finally the plug-in rod contacts the surface of the plug-in plate. Under the action of the force, the plug-in rod slides along the surface of the plug-in plate. When the plug-in rod slides into the plug-in hole of the plug-in plate, the tension spring restores the deformation to pull the plug-in rod to insert into the plug-in plate, and the plug-in plate is limited, so that the laser rangefinder with the plug-in plate is placed stably.

[0009] The motor is started to drive the output shaft to rotate, so as to drive the mounting plate to rotate, and then drive the laser rangefinder to move, and adjust the position of the laser rangefinder. The laser rangefinder can measure the height difference of the ground by emitting a laser beam and receiving a reflected beam, so as to determine the size of the slope. In this process, when the motor drives the output shaft to rotate, it can drive the rotating disk to rotate, and the inner wall of the clamping hole squeezes the clamping ball to push the guide plate to move. Under the action of the connecting disk, the spring is deformed, and finally the clamping ball is separated from the clamping hole. Under the action of the force, the clamping ball slides along the surface of the rotating seat. When the clamping ball slides into the next clamping hole, the spring restores the deformation to pull the clamping ball into the clamping hole, limit the rotating disk, and then limit the output shaft of the motor, and finally refine the position of the laser rangefinder.

[0010] The beneficial effect of the utility model is that the scheme pushes the laser rangefinder to contact the mounting plate so that the plug-in plate is inserted into the mounting plate. Under the action of the tension spring, the plug-in rod and other structures, the plug-in plate can be plugged in so that the plug-in plate drives the laser rangefinder to be stably placed, which is convenient for the operator to quickly install and use. Through the driving action of the motor, the mounting plate can be driven to rotate, and then the position of the laser rangefinder can be adjusted, which is convenient for the operator to measure and use. Under the action of the clamping hole, the clamping ball and other structures, the output shaft of the motor can be limited, and then the position of the laser rangefinder can be finely processed.

[0011] Furthermore, an end plate is fixedly connected to the upper end of the insertion rod, and the end plate is in contact with the mounting plate. The provision of the end plate facilitates the insertion rod to be pulled for mobile use.

[0012] Furthermore, a friction groove is provided on the surface of the end plate, and a plurality of the friction grooves are provided. The plurality of friction grooves are evenly distributed on the end plate. By providing the friction grooves, the friction effect of the end plate can be improved, and it is convenient for operators to use.

[0013] Furthermore, a tension spring is welded to the outer side of the second end, and the other end of the tension spring is welded to the first end. Through the provision of the tension spring, the insertion rod can be connected for use.

[0014] Furthermore, a clamping hole is provided on the back side of the rotating seat, and the output shaft of the motor is fixedly connected to a rotating disk, and a guide plate is slidably connected to the inside of the rotating disk, and a clamping ball is fixedly connected to the end face of the guide plate close to the rotating seat, and the clamping ball is slidably connected to the clamping hole, and the end face of the guide plate away from the rotating seat is fixedly connected to a connecting disk, and a spring is provided on the outer side of the guide plate, which can be driven by the driving action of the motor to drive the mounting plate to rotate, and under the action of the clamping hole, the clamping ball and other structures, the rotating disk can be limited, and then the output shaft of the motor can be limited, so as to complete the precise control of the position of the mounting plate.

[0015] Furthermore, there are a plurality of the clamping holes, which are arranged in a circular array on the rotating seat. The arrangement of the clamping holes facilitates clamping with the clamping ball.

[0016] Furthermore, one end of the spring is welded to the connecting disk, and the other end of the spring is welded to the rotating disk. Through the setting of the spring, the connecting disk can be connected for use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the upper end of the insertion rod 7 is fixedly connected with an end plate 8, and the end plate 8 is in contact with the mounting plate 4. The setting of the end plate 8 makes it easy to pull the insertion rod 7 for movement. The surface of the end plate 8 is provided with a friction groove, and there are multiple friction grooves. The multiple friction grooves are evenly distributed on the end plate 8. The setting of the friction grooves can improve the friction effect of the end plate 8, which is convenient for operators to use. A tension spring 9 is welded to the outer side of the end 2 71, and the other end of the tension spring 9 is welded to the end 1 61. The setting of the tension spring 9 allows the insertion rod 7 to be connected for use.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, a clamping hole 10 is provided on the back of the rotating seat 2, and the output shaft of the motor 3 is fixedly connected to a rotating disk 11, and a guide plate 12 is slidably connected inside the rotating disk 11.

[0028] The specific implementation process of the utility model is as follows: by pushing the laser rangefinder 5 to contact the mounting plate 4, the plug plate 6 is inserted into the mounting plate 4. In this process, when the oblique end of the plug plate 6 contacts the round end of the plug rod 7, the plug rod 7 drives the end 2 71 to move under the extrusion of the force. Under the action of the end 1 61, the tension spring 9 is deformed, and finally the plug rod 7 contacts the surface of the plug plate 6.

In this process, when the motor 3 drives the output shaft to rotate, the rotating disk 11 can be driven to rotate, and the inner wall of the clamping hole 10 squeezes the clamping ball 13 to push the guide plate 12 to move. Under the action of the connecting disk 14, the spring 15 is deformed, and finally the clamping ball 13 is separated from the clamping hole 10. Under the action of the force, the clamping ball 13 slides along the surface of the rotating seat 2. When the clamping ball 13 slides into the next clamping hole 10, the spring 15 restores the deformation to pull the clamping ball 13 into the clamping hole 10, limit the rotating disk 11, and then limit the output shaft of the motor 3, and finally refine the position of the laser rangefinder 5.

[0030] This solution pushes the laser rangefinder 5 to contact the mounting plate 4 so that the plug plate 6 is inserted into the mounting plate 4. Under the action of the tension spring 9, the plug rod 7 and other structures, the plug plate 6 can be plugged in so that the plug plate 6 drives the laser rangefinder 5 to be stably placed, which is convenient for the operator to quickly install and use.
