Description

Technical Field

[0001] The utility model relates to a slope measuring device, in particular to a foundation pit side slope measuring device, belonging to the technical field of slope measuring devices. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. It is mainly used to provide space for foundation construction. The slope of the foundation pit needs to be measured after the excavation is completed. Generally, a slope measuring instrument is used to measure the slope of the foundation pit. During measurement, the slope measuring instrument is held in hand so that one side of it contacts the inner wall of the foundation pit whose slope needs to be measured, and then the adjustment knob on the measuring instrument is turned. As the adjustment knob is turned, the spirit level will rotate. When the spirit level is adjusted to horizontal, the scale pointed by the pointer is the slope at that location, thereby realizing the measurement of the slope.

[0003] However, traditional slope measuring instruments require the user to hold the instrument with their hands during the slope measurement process, which wastes physical energy. In addition, since the user needs to hold the instrument with their hands all the time, it is not convenient to free both hands to record the measurement data, making it inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a foundation pit slope gradient measuring device in order to solve the above problems. During the measurement process, the measuring instrument can be fixed on the soil slope, thereby avoiding the need to hold the measuring instrument with hands all the time, saving physical strength and freeing up both hands to record measurement data, making it more convenient to use.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a foundation pit slope measuring device, including a slope measuring instrument body, the bottom end of the slope measuring instrument body is fixedly connected to a base plate, four insertion rods are slidably connected to the base plate, a fixed structure is provided on the base plate, the fixed structure includes a pull plate and a stop block, a pull plate is slidably connected to the base plate, four stop blocks are fixedly connected to the pull plate, four sliders are slidably connected to the base plate, the sliders are in contact with adjacent stop blocks, a clamping rod is fixedly connected to the slider, two clamping slots are fixedly connected to the insertion rod, and the clamping rod is clamped with adjacent clamping slots.

[0006] Preferably, the cross-section of one end of the insertion rod is a conical structure, and the cross-section of the other end of the insertion rod is a T-shaped structure.

[0007] Preferably, a return spring is fixedly connected to the slider, and the return spring is fixedly connected to the base plate.

[0008] Preferably, the entire cross-section of the slider is L-shaped, and the cross-section of one end of the slider is trapezoidal.

[0009] Preferably, the cross-section of one end of the pull plate is L-shaped, and the cross-section of the stop block is trapezoidal.

[0010] Preferably, the pull plate is arranged in the middle of the bottom plate, the clamping rod is perpendicular to the slider, and the two sliders located on both sides of the pull plate are symmetrically arranged about the middle of the pull plate.

[0011] Preferably, an adjusting knob is rotatably connected to the slope measuring instrument body, a rotating sleeve is rotatably connected to the slope measuring instrument body, and a level is installed on the rotating sleeve.

[0012] Preferably, a pointer is fixedly connected to the rotating sleeve, a scale plate is installed on the slope measuring instrument body, and one end of the pointer points to the scale plate.

[0013] The beneficial effect of the present invention is that when it is necessary to measure the slope of the foundation pit slope, the slope measuring instrument body can be held in hand and moved to insert the four insertion rods into the interior of the soil slope. Since the cross-section of one end of the insertion rod is a tapered structure, it is more labor-saving when the insertion rod enters the interior of the soil slope. When the bottom plate and the soil slope collide with each other, the slope measuring instrument body can be loosened. At this time, since the four insertion rods are inserted into the interior of the soil slope, the slope measuring instrument body can be fixed, avoiding the need to hold the slope measuring instrument body with hands all the time during the measurement process, saving physical effort and making it convenient to free up both hands for measurement. The measurement data is recorded, which makes it more convenient to use. When the slope measurement is not needed, the pull plate can be pulled, and the pull plate drives the four blocks to move. The movement of the blocks will interfere with the movement of the slider, and the slider will drive the clamping rod to move away from the clamping slot. When the clamping rod is not engaged with one of the clamping slots, multiple plug rods can be pulled in turn. As the plug rod moves, the plug rod will engage with another clamping slot. At this time, the plug rod cannot move. Since the sharp part of the end of the plug rod is located inside the bottom plate at this time, the sharp part of the end of the plug rod can be avoided from injuring people and other objects during transportation and storage, thereby effectively improving the safety of use.

[0022] As a technical optimization solution of the utility model, Figure 5 As shown, the cross section of one end of the insertion rod 3 is a tapered structure, and the cross section of the other end of the insertion rod 3 is a T-shaped structure, so that the insertion rod 3 can be easily pulled.

[0023] As a technical optimization solution of the utility model, Figure 4 As shown, a return spring 406 is fixedly connected to the slider 403 , and the return spring 406 is fixedly connected to the bottom plate 2 , so that the latching rod 404 can automatically engage with the latching slot 405 under the action of the return spring 406 .

[0024] As a technical optimization solution of the utility model, Figure 4As shown, the entire cross section of the slider 403 is an L-shaped structure, and the cross section of one end of the slider 403 is a trapezoidal structure, so that the block 402 can resist the movement of the slider 403.

[0025] As a technical optimization solution of the utility model, Figure 3 and Figure 4 As shown, the pull plate 401 is arranged in the middle of the bottom plate 2, the clamping rod 404 is perpendicular to the slider 403, and the two sliders 403 on both sides of the pull plate 401 are symmetrically arranged about the middle of the pull plate 401. The cross-section of one end of the pull plate 401 is an L-shaped structure, and the cross-section of the stop block 402 is a trapezoidal structure, so that the pull plate 401 can be easily pulled.

[0026] As a technical optimization solution of the utility model, Figure 1 As shown, the slope measuring instrument body 1 is rotatably connected to an adjusting knob 5, the slope measuring instrument body 1 is rotatably connected to a rotating sleeve 6, the rotating sleeve 6 is mounted with a level 7, the rotating sleeve 6 is fixedly connected with a pointer 8, the slope measuring instrument body 1 is mounted with a dial 9, one end of the pointer 8 points to the dial 9, so that the slope can be measured.

[0027] When the slope measuring device 1 is used, the slope measuring device 1 can be held in the hand and moved to the slope measuring device body 1 so that the four insertion rods 3 are inserted into the interior of the soil slope. Since the cross-section of one end of the insertion rod 3 is a tapered structure, it is more labor-saving in the process of the insertion rod 3 entering the interior of the soil slope. When the base plate 2 and the soil slope are in conflict, the slope measuring device body 1 can be loosened. At this time, since the four insertion rods 3 are inserted into the interior of the soil slope, the slope measuring device body 1 can be fixed, avoiding the need to hold the slope measuring device body 1 with hands all the time during the measurement process, saving physical effort and also facilitating the freeing of hands to record the measurement data, making it more convenient to use. When measuring, the adjusting knob 5 can be turned, and the turning of the adjusting knob 5 will cause the rotating sleeve 6 to rotate.

At this time, the slope here can be known by the reading on the dial 9 pointed by the pointer 8, thereby realizing the measurement of the slope When the slope measurement is not needed, the pull plate 401 can be pulled, and the pull plate 401 drives the four blocks 402 to move. The movement of the blocks 402 will interfere with the movement of the slider 403, and the return spring 406 will contract. The slider 403 will drive the clamping rod 404 to move away from the clamping slot 405. When the clamping rod 404 is not engaged with one of the clamping slots 405, multiple insertion rods 3 can be pulled in sequence. Since there is a certain friction between the insertion rod 3 and the bottom plate 2, after the insertion rod 3 is released, it will not fall under the action of gravity. When the four insertion rods 3 are pulled a certain distance, the pull plate 401 can be pulled in the opposite direction to reset it, and then the insertion rod 3 can be pulled. As the insertion rod 3 moves, the locking rod 404 will be engaged with another locking groove 405 under the action of the reset spring 406. At this time, the insertion rod 3 cannot move. Since the sharp part of the end of the insertion rod 3 is located inside the bottom plate 2 at this time, the sharp part of the end of the insertion rod 3 can be prevented from injuring people and other objects during transportation and storage, thereby effectively improving the safety of use.
