Description

Technical Field

[0001] The utility model relates to the technical field of slope detection, in particular to a slope detection device. Background Art

[0002] In road engineering, whether the roadbed is constructed through fill or cut, slopes naturally form afterwards. The quality of slope construction directly impacts the overall quality and safety of the entire road, making its importance self-evident. Precise slope control is particularly crucial during the detailed finishing of slopes after excavation. This not only ensures the stability of the road structure but also prevents potential safety hazards, ensuring long-term safe and smooth road use.

[0003] The Chinese patent publication number CN219736350U discloses a slope detection device. Under the action of an adjustment mechanism, the mounting seat and the mounting plate can be fixed to the high end of the slope through an insert rod and a connecting cone head, and the height of the four corners of the mounting seat can be adjusted individually by rotating a threaded sleeve, ensuring that the mounting seat and the mounting plate can be adjusted to a horizontal state, making the detection more accurate. Under the action of the measuring mechanism, the measuring plate can drive the pointer to rotate when it fits the slope. The staff can directly read the reading on the side of the display board to obtain the slope of the slope, which facilitates detection, makes the detection process more concise, and increases the practicality of the device.

[0004] However, the above patent is cumbersome and time-consuming to use, which reduces the efficiency of slope detection. Moreover, if the slope is high, in order to ensure the accuracy of the detection, it is usually necessary to detect at multiple positions on the slope and perform statistical analysis on the multiple detected data. However, since the above patent needs to be fixed on the high end of the slope for use, it is unable to detect the middle area and the lower area of ​​the slope, and its practicality is poor. Utility Model Content

[0005] The purpose of the present utility model is to provide a slope detection device to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0007] A slope detection device includes a base plate, a scale measuring plate is installed on the upper surface of the base plate, a rotating shaft is passed through the inside of the scale measuring plate and is rotatably connected, a counterweight pointer is installed at one end of the rotating shaft, side plates are installed on both side surfaces in the width direction of the base plate, a first extension plate is inserted into the inside of the side plate, and a second extension plate is inserted into the inside of the first extension plate, and an abutment plate is installed on the side of the scale measuring plate away from the counterweight pointer through a moving mechanism, and the abutment plate is used to clamp and fix the rotating shaft.

[0008] It can be seen that by placing the base plate on the slope, the counterweight pointer automatically moves vertically downward under the action of gravity. At this time, the slope detection can be quickly completed by directly observing the scale indicated by the counterweight pointer. It is simple to operate and portable to use, and can improve the efficiency of slope detection. Moreover, by setting the side plates, the first extension plate and the second extension plate, the length of the base plate can be extended so that the operator can stand on the top or bottom of the slope to complete the detection of different areas of the entire slope. It is highly practical. Moreover, when observing the scale, the operator needs to be directly in front of the counterweight pointer to avoid sideways observation causing perspective deviation, which affects the detection result. However, if the operator stands directly on the slope, there is a risk of slipping and falling. Therefore, through the setting of the moving mechanism, the abutment plate can be remotely driven to press against the rotating shaft to fix the counterweight pointer, and then the base plate can be retracted for observation.

[0009] Furthermore, the moving mechanism includes a screw rotatably installed inside the base plate, and the lower end of the abutment plate is installed on the outer surface of the screw. A telescopic rod is rotatably installed inside the base plate along its length direction, and a second bevel gear is sleeved on the outer surface of the telescopic rod. A first bevel gear is installed at the end of the screw, and the first bevel gear is meshed with the second bevel gear.

[0010] When the rotating telescopic rod drives the second bevel gear to rotate, the second bevel gear and the first bevel gear are engaged with each other, so the screw can be driven to rotate. When the screw rotates, the abutment plate is driven to move on it, so that the abutment plate can be pressed against the end of the rotating shaft to fix the counterweight pointer, making it convenient to retract the base plate to observe the scale.

[0011] Furthermore, a hand-held plate is commonly installed at the ends of the two second extension plates, and the end of the telescopic rod passes through the other side of the hand-held plate and is installed with a knob.

[0012] The setting of the hand-held plate not only provides a hand grasping position, but also connects the telescopic rod and the second extension plate together. When the second extension plate is extended or retracted, the telescopic rod can also be driven to extend or retract, thereby satisfying the operation of remotely driving the abutment plate to press against the rotating shaft.

[0013] Furthermore, fastening bolts for fixing the first extension plate are installed on the outer surface of the side plate.

[0014] After the first extension plate is stretched outward to a suitable length, the fastening bolts are tightened to fix the first extension plate.

[0015] Furthermore, an inner groove is provided inside the second extension plate, a push rod is provided inside the inner groove, a plurality of sockets are provided on the outer surface of the first extension plate along its length direction, and the push rod is adapted to the sockets, a spring is provided inside the inner groove, and the two ends of the spring are respectively in contact with the inner wall of the inner groove and the push rod.

[0016] When extending the length of the second extension plate outward, first press the push rod inward to retract it into the first extension plate, and then slide the second extension plate inside the first extension plate. When it reaches the appropriate length, use the elastic force of the spring to push the push rod outward and insert it into the socket.

[0017] Furthermore, universal wheels are installed on both sides of the bottom of the side panel in the length direction.

[0018] The setting of the universal wheel makes it easy to push the bottom plate to slide on the slope surface for testing different areas.

[0019] Furthermore, a bearing is sleeved on the outer surface of the screw, a connecting plate is installed on the outer surface of the bearing, and the end of the connecting plate is connected to the inner wall of the base plate.

[0020] The setting of the bearing and the connecting plate can support the screw, improve its structural stability, and make it rotate more smoothly.

[0021] Furthermore, a rubber pad is provided at the end of the abutting plate corresponding to the rotating shaft, and an outer surface of the rubber pad is provided with anti-slip grooves.

[0022] The provision of the rubber pad and the anti-slip grooves can increase the friction between the abutment plate and the rotating shaft, thereby improving the fixing effect on the rotating shaft. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-5 As shown, a slope detection device includes a base plate 100, a scale measuring plate 101 is installed on the upper surface of the base plate 100, a rotating shaft 102 is passed through the interior of the scale measuring plate 101 and is rotatably connected, a counterweight pointer 103 is installed at one end of the rotating shaft 102, side plates 104 are installed on both side surfaces in the width direction of the base plate 100, a first extension plate 105 is inserted into the interior of the side plate 104, and a second extension plate 106 is inserted into the interior of the first extension plate 105, and an abutment plate 107 is installed on the side of the scale measuring plate 101 facing away from the counterweight pointer 103 through a moving mechanism 200, and the abutment plate 107 is used to clamp and fix the rotating shaft 102.

[0031] When in use, by placing the base plate 100 on the slope, the counterweight pointer 103 automatically moves downward vertically under the action of gravity. At this time, the slope detection can be quickly completed by directly observing the scale indicated by the counterweight pointer 103. It is simple to operate and portable, and can improve the efficiency of slope detection. In addition, by setting the side plates 104, the first extension plate 105 and the second extension plate 106, the length of the base plate 100 can be extended, so that the operator can stand on the top or bottom of the slope to complete the detection of different areas of the entire slope. It is highly practical. In addition, when observing the scale, the operator needs to be in front of the counterweight pointer 103 to avoid side observation causing perspective deviation, which affects the detection result. However, if the operator stands directly on the slope, there is a risk of slipping and falling. Therefore, through the setting of the moving mechanism 200, the abutment plate 107 can be remotely driven to press against the rotating shaft 102 to fix the counterweight pointer 103, and then the base plate 100 can be retracted for observation.

[0032] Specifically, the moving mechanism 200 includes a screw 201 rotatably mounted inside the base plate 100, and the lower end of the abutment plate 107 is mounted on the outer surface of the screw 201. A telescopic rod 203 is rotatably mounted inside the base plate 100 along its length direction, and a second bevel gear 204 is sleeved on the outer surface of the telescopic rod 203. A first bevel gear 202 is mounted on the end of the screw 201, and the first bevel gear 202 is meshed with the second bevel gear 204. When the telescopic rod 203 is rotated to drive the second bevel gear 204 to rotate, the second bevel gear 204 and the first bevel gear 202 are meshed with each other, so that the screw 201 can be driven to rotate. When the screw 201 rotates, the abutment plate 107 is driven to move thereon, so that the abutment plate 107 can be pressed against the end of the rotating shaft 102, fixing the counterweight pointer 103, and facilitating the retraction of the base plate 100 to observe the scale.

[0033] Specifically, a hand-held plate 300 is installed at the ends of the two second extension plates 106. The end of the telescopic rod 203 passes through the other side of the hand-held plate 300 and is installed with a knob 301. Through the setting of the hand-held plate 300, not only a hand grasping position is provided, but the hand-held plate 300 also connects the telescopic rod 203 and the second extension plate 106 together. When the second extension plate 106 is extended or retracted, the telescopic rod 203 can also be driven to extend or retract, thereby satisfying the operation of remotely driving the abutment plate 107 to press against the rotating shaft 102.

[0034] Specifically, fastening bolts 400 for fixing the first extension plate 105 are installed on the outer surface of the side plate 104. After the first extension plate 105 is stretched outward to a suitable length, the fastening bolts 400 are tightened to fix the first extension plate 105.

[0035] Specifically, an inner groove 500 is provided inside the second extension plate 106, and a push rod 501 is provided inside the inner groove 500. A plurality of insertion holes 502 are provided on the outer surface of the first extension plate 105 along its length direction, and the push rod 501 is adapted to the insertion holes 502. A spring 503 is provided inside the inner groove 500, and the two ends of the spring 503 are respectively in contact with the inner wall of the inner groove 500 and the push rod 501. When the length of the second extension plate 106 is extended outward, the push rod 501 is first pressed inward to shrink it into the first extension plate 105, and then the second extension plate 106 can be slid inside the first extension plate 105. After reaching the appropriate length, the elastic force of the spring 503 is used to push the push rod 501 outward and insert it into the insertion hole 502.

[0036] Specifically, universal wheels 600 are installed on both sides of the bottom of the side panel 104 in the longitudinal direction. The arrangement of the universal wheels 600 facilitates pushing the bottom panel 100 to slide on the slope for detecting different areas.

[0037] Specifically, the outer surface of the screw 201 is sleeved with a bearing 700, and the outer surface of the bearing 700 is installed with a connecting plate 701. The end of the connecting plate 701 is connected to the inner wall of the base plate 100. Through the setting of the bearing 700 and the connecting plate 701, the screw 201 can be supported, thereby improving its structural stability and making it rotate more smoothly.

[0038] Specifically, a rubber pad is provided at the end of the abutment plate 107 corresponding to the rotating shaft 102, and the outer surface of the rubber pad is provided with anti-slip grooves. By setting the rubber pad and the anti-slip grooves, the friction between the abutment plate 107 and the rotating shaft 102 can be increased, thereby improving the fixing effect of the rotating shaft 102.
