[0002] The slope angle measuring equipment for highway design is mainly used for measuring and evaluating the inclination angle of slopes (such as embankments, cuts, side slopes, etc.) along the road to ensure that it meets the engineering safety standards and design requirements. Current inclination angle measuring equipment includes inclinometers, total stations, and simple slope rulers, but most of the measuring equipment is prone to landslides when placed obliquely, reducing the measurement efficiency. To solve this technical problem, for example, a highway construction slope measuring device is disclosed in Chinese patent (Patent Publication No. CN219265293U), which can twist the adjusting ring to drive the support column to extend and retract in the installation cylinder, thereby conveniently and stably supporting the bottom plate horizontally. At the same time, the adjusting rod can be twisted to drive the adjusting wheel to rotate on the shaft body, so that the staff is attached to the road slope surface, and the specific angle of the indicating needle on the protractor is read, which is the inclination angle of the slope. The staff is rotated by the adjusting wheel, making it easy to use different angles of slope, improving the versatility of the measuring device.

[0003] The above technical solution provides a slope measuring device, but the operation is complicated when in use. It needs to use the leveling mechanism to level first, then rotate the adjusting rod to indirectly drive the staff to rotate, and finally the angle pointed by the staff is the inclination angle of the slope.

DETAILED DESCRIPTION

[0021] As shown in Figures 1-4 ,

[0022] The utility model provides a kind of slope angle measuring equipment for highway design, including slope ruler body 1 and movable disc 2 rotationally arranged on its surface, the side surface of the slope ruler body 1 is provided with through hole along its width direction, the movable disc 2 is coaxially rotated in through hole and is vertically arranged, the both side surfaces of the slope ruler body 1 are provided with scale gauge coaxially surrounded in the outer circle of through hole, the both side surfaces of the movable disc 2 are fixed with pointer for pointing to scale gauge, the inside of the movable disc 2 is fixed with weight 3 corresponding with the position of scale gauge, and movable disc 2 makes pointer always keep vertical downward under the action of weight 3, one side surface of the slope ruler body 1 is elastically slidably connected with vertically moving button 4, spring is arranged between button 4 and slope ruler body 1, and the lower end between button 4 and movable disc 2 is equipped with limiting component in the slope ruler body 1, the limiting component includes horizontally arranged limiting block 7 and connecting rod 5 fixed in the lower end of button 4, the limiting block 7 is semicircular arc, the limiting block 7 is elastically slidably arranged in the slope ruler body 1 and close to movable disc 2 in horizontal plane, vertical fixed linkage block 6 is arranged on the side surface of limiting block 7 away from movable disc 2, one end of linkage block 6 and one end of connecting rod 5 are all bevelled and mutually adhere, and when button 4 moves in vertical direction towards down, one end of connecting rod 5 is driven by button 4 to abut linkage block 6 in sliding contact mode, and drive linkage block 6, limiting block 7 moves towards movable disc 2, so that the surface of limiting block 7 abuts the surface of movable disc 2 and limits its movement, the inside of the slope ruler body 1 is equipped with angular displacement sensor 8 for detecting the rotation of movable disc 2, and angular displacement sensor 8 is electrically connected with main controller (main controller is not shown in the figure), and the outer surface of the slope ruler body 1 is equipped with three display screens 9 for showing slope, three display screens 9 are arranged on the upper surface and the left and right two side surfaces of the slope ruler body 1 respectively, and each display screen 9 is electrically connected with main controller.

[0023] When the slope of the road needs to be detected, the lower end surface of the slope ruler body 1 is directly placed on the slope, and the length direction of the slope ruler body 1 is kept parallel to the length direction of the slope. At this time, the weight 3 in the movable block will drive the movable block to deflect a certain angle under the action of gravity. Since the position of the pointer corresponds to the position of the weight 3, the pointer will also rotate with the weight 3 and always point vertically to the ground. At this time, the scale pointed to by the pointer represents the slope value of the road. The angular displacement sensor 8 also detects the angle of deflection of the movable disc 2 (when the bottom end of the slope ruler body 1 is placed on the water surface, the position of the movable disc 2 detected by the angular displacement sensor 8 is the initial position, and the angle of deflection can be obtained by comparing the initial position with the deflected angle of the movable disc 2). The angular displacement sensor 8 transmits the detected data to the main controller, and the current slope value can be displayed on each display screen 9 through the pre-set program in the main controller, which is convenient for workers to intuitively view the data, simple and convenient to operate, and greatly improves the work efficiency of workers. After the movable disc 2 is deflected a certain angle under the action of the weight 3, the worker can press the button 4 vertically downward, and fix the movable disc 2 at the current position through the cooperation of the linkage block 6 and the limiting block 7. At this time, the worker can take up the slope ruler body 1 to conveniently view the slope value. Since the movable disc 2 is fixed, the slope value displayed on the display screen 9 will not change, and the previously detected slope value will always be displayed, effectively improving the flexibility and convenience of the device (a kind of slope angle measuring device for highway design) in use. Of course, we can also write corresponding programs in the controller to enable the display screen 9 to record multiple measured slope values, which is convenient for workers to observe. We can also set a corresponding Bluetooth module in the first shell 101 to connect with the mobile phone end, and view the historical slope value through the mobile phone end.

[0024] In the present embodiment, the slope ruler body 1 is composed of a first shell 101 and a second shell 102 which are hinged to each other in the horizontal plane. The lengths of the first shell 101 and the second shell 102 are equal, and the hinge of the first shell 101 and the second shell 102 is provided with damping. The movable disc 2, the display screen 9, the button 4 and the limiting assembly are all arranged on the first shell 101. The surface of the second shell 102 is provided with a through holding hole arranged along the width direction thereof, and the inner side of the holding hole is provided with a continuous smooth curved surface which conforms to human engineering.

[0025] In combination with Figure 3 The slope ruler body 1 is composed of a first shell 101 and a second shell 102 which are hinged to each other and have equal lengths. When not in use, the first shell 101 and the second shell 102 can be folded up, reducing the floor area and facilitating portability.

[0026] In the embodiment, the two side surfaces of the first shell 101 are fixedly connected with transparent first protective covers 10 through buckling, each of the first protective covers 10 is circular, and each of the first protective covers 10 covers the movable disc 2 and the corresponding scale.

[0027] As shown in the drawings, the first protective cover 10 can be made of transparent plastic material, which can effectively protect the scale and the movable disc 2, prevent the external environment from interfering with the movement of the movable disc 2, and ultimately ensure the accuracy of the scale pointed by the pointer.

[0028] In the embodiment, the lower surface of the second shell 102 is provided with a placing groove, and a vertically movable fixing block 11 is slidably connected in the placing groove, the fixing block 11 is in a cylindrical shape, the lower end of the fixing block 11 is conical after being guided at an angle, and the circumferential surface of the fixing block 11 is fixedly connected with a protrusion outside the second shell 102.

[0029] As shown in the drawings, Figure 3 and Figure 4 , the position of the protrusion is pushed down in the vertical direction, which will simultaneously drive one end of the fixing block 11 to extend out of the second shell 102, the extended end of the fixing block 11 can be vertically inserted into the ground, and the slope scale body 1 can be fixed on the slope surface, which can expand the use scenarios of the device; and the first shell 101 and the second shell 102 can be rotated to a certain angle (for example, the first shell 101 and the second shell 102 are rotated so that the included angle between them is 90°), and due to the damping provided at the hinge between the first shell 101 and the second shell 102, the device will remain in this state, at this time, when measuring the slope value of the road, only the length direction of the first shell 101 needs to be parallelly arranged with the length direction of the slope, and the fixing block 11 on the second shell 102 is inserted into the ground, so that the slope scale body 1 can be fixed on the road surface, and the device is more stable than when the first shell 101 and the second shell 102 are not folded.

[0030] In the embodiment, the side surface of the first shell 101 away from the second shell 102 is slidably connected with a vertically movable sliding block 12, one side surface of the sliding block 12 is provided with a horizontally placed laser emitter 13, and the outer surface of the first shell 101 is detachably connected with a transparent second protective cover 14 for covering the laser emitter 13.

[0031] In combination with the drawings, the second protective cover 14 can be made of transparent plastic material, when the slope ruler body 1 is fixed on the road surface, the laser emitted by the laser emitter 13 should be parallel to the slope of the road, which is convenient for measuring the slope value of the road at night, and ensures that the slope ruler body 1 can be placed on the road surface in the correct position; the position of the laser emitter 13 can be adjusted vertically within a certain range through the sliding block 12, which indirectly adjusts the vertical distance between the laser emitted by the laser emitter 13 and the slope surface, which is convenient for the staff to observe the path of the laser.

[0032] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application.
