Description

Technical Field

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

[0002] Bridge slope measurement plays a crucial role in design, construction, and maintenance. A reasonable slope not only ensures safe and comfortable driving, but also helps effectively drain water from the bridge, reducing road damage and potential traffic accidents caused by accumulated water.

[0003] Traditionally, a bubble level, a fundamental tool for slope measurement, determines whether a level has been reached by observing the position of a bubble within a closed container. When the bubble is centered, the instrument is horizontal. While this method is simple and easy to use, it also has significant drawbacks. To ensure accurate measurement data, operators must meticulously adjust the instrument until the bubble is stabilized in the center, a process that is often time-consuming and inefficient. Furthermore, bubble levels are susceptible to external influences. Temperature fluctuations or even slight vibrations can cause the bubble to shift, affecting the final measurement result.

[0004] In view of this, it is particularly necessary to develop a more accurate, efficient and stable bridge slope measurement device. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a more accurate, efficient and stable bridge slope measuring device.

A slot is provided on one side of the grip frame for holding during use. Degree disks are provided on the front and rear sides of the grip frame, and a mounting shaft is provided at the center of the degree disks on both sides. Bearings are provided on the mounting shafts, and pointers for indicating the slope value are provided on the bearings. The lower end of the pointer is connected to a weight block, and a chuck that is slidably engaged with the pointer on the same side is also provided on the mounting shaft. A mounting frame located between the two mounting shafts is provided inside the grip frame, and a dial plate is rotatably provided on the slotted inner wall of the grip frame. A connecting rope is symmetrically and slidably passed through the interior of the mounting frame, and the two ends of the connecting rope are respectively connected to the chuck and the dial plate on the same side, so as to pull the chuck to move, and an elastic member is provided between the chuck and the mounting frame.

[0007] More preferably, a guide ring and an indicator needle are included. The front and rear sides of the grip frame are both provided with guide rings located at the outer circle of the degree dial on the same side, and the guide rings are concentrically arranged with the degree dial. Indicator needles are slidingly arranged at intervals on the guide rings to assist in recording numerical values.

DETAILED DESCRIPTION

[0020] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0021] Embodiment: A bridge slope measuring device, such as Figures 1-4 As shown, it includes a grip frame 1, a degree disk 2, a mounting shaft 3, a bearing 4, a pointer 5, a weight block 6, a mounting frame 7, a dial plate 8, a connecting rope 9, a chuck 10 and an elastic member 11. A slot is provided on the right side of the grip frame 1 for holding during use. Degree disks 2 are provided on the front and back sides of the grip frame 1, as well as mounting shafts 3 located at the center of the degree disks 2 on both sides. The degree disk 2 is used to display the measured slope value, so that the slope can be perceived intuitively through the data. Bearings 4 are provided on the mounting shafts 3. 4 is provided with a pointer 5 for indicating the slope value, which makes the support of the pointer 5 more stable, allowing the pointer 5 to rotate stably, thereby ensuring the accuracy of the measurement result. The lower end of the pointer 5 is connected with a weight block 6, which drives the pointer 5 to point to the correct slope value by utilizing gravity to achieve a fast and accurate measurement effect. A chuck 10 that is engaged with the pointer 5 on the same side is also slidably provided on the mounting shaft 3. The chuck 10 slides back and forth and can move away from and close to the pointer 5 on the same side, thereby utilizing the chuck to adjust the position of the pointer 5. The rotation of the pointer 5 is limited to stabilize the pointing of the pointer 5 and determine the measured slope value. A mounting frame 7 located between the two mounting shafts 3 is provided inside the grip frame 1, and a dial plate 8 is rotatably provided on the slotted inner wall of the grip frame 1. A connecting rope 9 is symmetrically slid through the interior of the mounting frame 7. The left and right ends of the connecting rope 9 are respectively connected to the chuck 10 and the dial plate 8 on the same side. The connecting rope 9 can be pulled by toggling the dial plate 8, thereby moving the chuck 10 on the mounting shaft 3. When the chuck 10 is engaged with the pointer 5, the rotation of the bearing 4 is synchronously limited, so that the pointing position of the pointer 5 is fixed, and an elastic member 11 is provided between the chuck 10 and the mounting frame 7. In this embodiment, the elastic member 11 is a spring, which can provide elastic force support for the reset of the chuck 10. In combination with the above, through the setting of the weight block 6 and the cooperation of the chuck 10, the device can present a more efficient, fast and accurate slope measurement effect, which not only reduces the workload of personnel, but also improves the overall measurement efficiency.

[0022] like Figure 1 and Figure 5 As shown, it also includes a guide ring 12 and an indicator needle 13. The front and rear sides of the grip frame 1 are both provided with a guide ring 12 located at the outer circle position of the degree disk 2 on the same side, and the guide ring 12 is concentrically arranged with the degree disk 2. The indicator needle 13 is slidingly arranged at intervals on the guide ring 12 to assist in recording the numerical value.

[0023] like Figure 6 As shown, it also includes a clamping rod 14 and an elastic member 15. The clamping rod 14 is slidably penetrated on the sliding sleeve of the indicator needle 13, and the elastic member 15 is provided between the clamping rod 14 and the corresponding indicator needle 13. In this embodiment, the elastic member 15 is a spring, and the end of the clamping rod 14 is in contact with the guide ring 12 on the same side. Through the action of the elastic member 15, the position of the indicator needle 13 can be kept stable to prevent the value from changing due to external vibration.

[0024] like Figure 1 As shown, a placement plate 16 is also included. The bottom of the grip frame 1 is provided with a placement plate 16 to provide a stable placement platform for the device.

[0025] like Figure 1 As shown, a cover plate 17 is also included. The degree disk 2 is provided with a cover plate 17, which is made of a transparent material and can protect the degree disk 2 from external damage without affecting the degree.

[0026] When it is necessary to measure the slope of the bridge, first hold the slotted position of the grip frame 1 and place the device at the slope to be measured, so that the placement plate 16 is placed stably in the measuring position. Affected by the inclination of the slope, the load block 6 droops under the action of gravity, and then the load block 6 presents a longitudinal vertical state, and at the same time drives the pointer 5 and the bearing 4 to rotate, so that the pointer 5 follows the drooping of the load block 6, thereby pointing to the corresponding value on the degree dial 2, and then the dial plate 8 can be dialed, and then the connecting rope 9 can be pulled, so that the chuck 10 is pulled by the connecting rope 9 and slides on the installation shaft 3, and the elastic member 11 is deformed accordingly, and then the chuck 10 follows the trajectory of the installation shaft 3 to fit with the pointer 5, thereby jamming the pointer 5 and the bearing 4, thereby limiting the pointer 5. The rotation of the indicator needle 13 allows it to accurately point to the numerical value of the bridge slope. Then, one of the indicator needles 13 is moved to slide on the guide ring 12, and the elastic member 15 is deformed accordingly, so that the clamping rod 14 slides on the corresponding indicator needle 13, thereby continuously contacting the guide ring 12, providing friction for the movement of the indicator needle 13, making it slide more smoothly, and wait until the indicator needle 13 points to the corresponding numerical position on the degree dial 2 to record the slope value at this position, and then the operation can be repeated. Because the setting of the weight block 6 makes the slope measurement faster, and at the same time, with the fixing effect of the chuck 10, the overall numerical presentation effect is more stable, which can not only improve the accuracy of the measurement, but also improve the measurement efficiency and reduce the workload of the staff.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
