Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to a multi-directional measurement device used for engineering measurement. Background Art

[0002] Engineering surveying is the process of measuring, recording and analyzing the project site and its surrounding environment using measuring instruments and methods during the construction process. Its purpose is to obtain information such as topography, building structure, underground pipelines, etc., to provide necessary data support for project planning, design, construction and operation, and to ensure project quality and safety.

[0003] The most widely used multi-directional measuring device in engineering surveying is the total station, which is a multifunctional measuring instrument that uses laser beams, infrared or electromagnetic waves to measure distance, angle and elevation. The total station is supported and fixed by a tripod during use, but when used in some wide surveying areas, there are often strong crosswinds, which has a great impact on the placement stability of the total station. The total station is heavier than the tripod, resulting in a higher center of gravity for the entire equipment during use. Strong winds are more likely to cause unstable placement problems, and excessive winds can cause the total station to vibrate, which has a great impact on the stability of the measurement.

The wind speed sensing feedback mechanism 7 includes an L-shaped vertical plate 71 fixedly connected to the upper end of the U-shaped bracket 10. The horizontal part of the L-shaped vertical plate 71 and the upper end of the U-shaped bracket 10 are rotatably connected to a column 72 through a bearing. The upper end of the column 72 is fixedly connected to a wind wheel 73. A booster box 74 is also fixedly installed on the upper end of the U-shaped bracket 10. A booster piston 75 is provided in a sealing sleeve in the booster box 74. The side wall of the booster piston 75 is fixed. Multiple pushing rods 76 are connected, one end of which extends out of the boosting box 74 and is fixedly connected to the same pushing plate 77. Multiple return springs 78 sleeved on the outside of the pushing rods 76 are fixedly connected between the pushing plate 77 and the boosting box 74. The lower end column wall of the column 72 is fixedly sleeved with a cam 79 located on one side of the pushing plate 77. The side wall of the boosting box 74 is fixedly connected to an air filling pipe 710 and an air supplement pipe 711. Both the air filling pipe 710 and the air supplement pipe 711 are provided with a one-way valve.

[0035] The upper side wall of the U-shaped bracket 10 is also fixedly provided with a wind speed self-changing regulating mechanism 8, which includes a feedback shell 81, one end of the gas filling pipe 710 is fixedly connected to the upper end of the feedback shell 81, and one side of the upper end of the feedback shell 81 is also fixedly connected with a small flow exhaust pipe 82, and a feedback piston 83 is provided in the sealing sleeve inside the feedback shell 81, and a push-pull rod 84 is fixedly connected to the lower end of the feedback piston 83, and a return spring 85 sleeved on the outside of the push-pull rod 84 is fixedly connected to the lower end of the feedback piston 83 and the bottom of the inner wall of the feedback shell 81, and the lower end of the feedback shell 81 is also fixedly connected to an insulating cover shell 86, and the inner wall of the insulating cover shell 86 is symmetrically fixedly connected with a height adjustment resistor rod 87 and The strengthening adjustment resistor rod 88 and the lower end of the push-pull rod 84 extend through the insulating cover 86. The lower end rod wall of the push-pull rod 84 is symmetrically fixedly connected with a height adjustment conductive contact 89 and a strengthening adjustment conductive contact 810. A starting switch 811 is also fixedly installed on the bottom of the inner wall of the insulating cover 86. The height adjustment conductive contact 89 and the height adjustment resistor rod 87 are in electrical contact, and the strengthening adjustment conductive contact 810 and the strengthening adjustment resistor rod 88 are in electrical contact. The height adjustment conductive contact 89 and the height adjustment resistor rod 87 are connected in series to the power supply circuit of the annular thrust electromagnetic plate 26, and the strengthening adjustment conductive contact 810 and the strengthening adjustment resistor rod 88 are connected in series to the power supply circuit of the strengthening electromagnetic plate 56.

[0036] The wind speed sensing feedback mechanism 7 and the wind speed self-changing adjustment mechanism 8 are connected and arranged, and the wind speed self-changing adjustment mechanism 8 is electrically connected to the measurement height self-regulating mechanism 2, and can adaptively adjust the center of gravity height of the entire measuring equipment based on the size of the external environmental wind force.

[0037] When the utility model is in use, the wind force of the external environment drives the wind wheel 73 to rotate, and the wind wheel 73 drives the column 72 to drive the cam 79 to rotate synchronously. After the protruding part of the cam 79 acts on the squeezing and pushing plate 77, the squeezing and pushing rod 76 overcomes the elastic force of the return spring 78 to drive the booster piston 75 to move in the booster box 74, and then the gas in the booster box 74 is transported to the feedback shell 81 through the gas filling pipe 710. The small flow exhaust pipe 82 at the upper end of the feedback shell 81 can discharge the gas pressed into the booster box 74 relatively. When the external environment wind force is too strong, the frequency of the gas pressed into the feedback shell 81 by the booster box 74 increases, so that the small flow exhaust pipe 82 cannot meet the balance of gas discharge, and then the feedback piston 83 drives the push-pull rod 84 downward under the action of the air pressure. The greater the wind force, the greater the downward movement distance of the feedback piston 83, so that the height adjustment The moving distance of the conductive contact 89 and the enhanced adjustment conductive contact 810 on the height adjustment resistor rod 87 and the enhanced adjustment resistor rod 88 is greater. The height adjustment conductive contact 89 and the height adjustment resistor rod 87 are connected in series to the power supply circuit of the annular thrust electromagnetic plate 26. The greater the moving distance of the height adjustment conductive contact 89, the greater the resistance value of the height adjustment resistor rod 87, thereby making the power supply current of the annular thrust electromagnetic plate 26 smaller, and the magnetic force of the annular thrust electromagnetic plate 26 smaller. Under the action of the compensation spring 25, the lifting rod 22 and the circular lifting plate 23 move downward relatively, and the installation center of gravity of the total station 9 is lowered. The center of gravity of the entire measuring device can be adaptively adjusted during the measurement work based on the wind force of the external environment during the measurement, thereby ensuring the stability of the measurement work and avoiding the problem that the wind force causes the measurement equipment to be unstable and thus affects the measurement quality;

[0038] The laser rangefinder 41 monitors the distance change between the circular lifting plate 23 and the upper end of the support tube 21, and then feeds back the change in the use height of the total station 9. The laser rangefinder 41 transmits the distance change data to the data translator 42, and the data translator 42 processes the data and stores the data in the data storage 43, which can record the height change data, which is convenient for the later verification of the measurement data;

[0039] The wind direction of the external environment drives the weather vane 63 to rotate. The weather vane 63 is an asymmetrically shaped object with its center of gravity fixed on the transmission shaft 62. When the wind blows, the end that produces greater resistance to air flow will rotate along the wind to display the wind direction. The lower end of the transmission shaft 62 drives the arc-shaped pressing block 65 to move to the wind direction position through the extension rod 64. When the arc-shaped pressing block 65 moves, it indicates that the arc-shaped pressing block 65 is disengaged from the trigger pressure switch 67, thereby connecting the working circuits of the annular drive electric slide rail 66 and the annular synchronous electric slide rail 51, and simultaneously disconnecting the power supply circuit of the reinforcing electromagnetic plate 56. The annular drive electric slide rail 66 and the annular synchronous electric slide rail 51 maintain the same angular velocity and move clockwise. The annular drive electric slide rail 66 drives the trigger pressure switch 67 to move synchronously. The annular synchronous electric slide rail 51 is connected to the connecting plate 52 and the connecting support The frame 53 drives the triangular wind-breaking plate 54 to move synchronously. When the trigger pressure switch 67 moves to the arc-shaped pressing block 65, it indicates that the triangular wind-breaking plate 54 moves to the position facing the wind direction, and the trigger pressure switch 67 is pressed by the arc-shaped pressing block 65, stopping the continued movement of the annular driving electric slide rail 66 and the annular synchronous electric slide rail 51, and synchronously connecting the power supply circuit of the reinforced electromagnetic plate 56. The reinforced electromagnetic plate 56 cooperates with the reinforced permanent magnet plate 57 to achieve the reinforced fixation of the lower side of the front end of the triangular wind-breaking plate 54, ensuring the stability of the triangular wind-breaking plate 54. The triangular wind-breaking plate 54 can effectively break the wind and avoid the problem of excessive wind causing large pressure damage to the measuring equipment. It can self-adjust the wind-breaking direction based on the wind force and direction, and provide the best wind-breaking protection for the measuring equipment, greatly reducing the problem of strong wind weather affecting the stability of the measuring equipment.

[0040] When the wind force is greater, the distance that the enhanced adjustment conductive contact piece 810 moves on the enhanced adjustment resistor rod 88 is greater, thereby reducing the access resistance of the enhanced adjustment resistor rod 88. The enhanced adjustment conductive contact piece 810 and the enhanced adjustment resistor rod 88 are connected in series to the power supply circuit of the enhanced electromagnetic plate 56, thereby enhancing the magnetic force of the enhanced electromagnetic plate 56, and strengthening the structure of the lower front end of the triangular wind-breaking plate 54, thereby ensuring the stable wind-breaking work of the triangular wind-breaking plate 54.

[0041] As the wind force increases to 25m / s, the lower end of the push-pull rod 84 acts on the start switch 811, thereby driving the dual-axis motor 35 to operate. The output ends of the dual-axis motor 35 drive the two rotating screws 33 to rotate synchronously through the bevel gear assembly 36. The threaded connection between the rotating screw 33 and the supporting plate 34 enables the supporting plate 34 to store the total station 9 into the storage tube 31. When the wind force reaches a certain level, the total station 9 can be quickly stored and protected, avoiding the problem of excessive wind force causing damage to the total station 9, and having better safety protection.

[0042] The utility model can adaptively adjust the center of gravity of the entire measuring device during the measuring work based on the wind force of the external environment during the measurement, thereby ensuring the stability of the measuring work and avoiding the problem that the measuring equipment is unstable due to wind force and thus affects the measurement quality. It can self-adjust the wind-breaking direction based on the wind force and direction, and provide the best wind-breaking protection for the measuring equipment, greatly reducing the problem that strong wind weather affects the stability of the measuring equipment. It can quickly store and protect the total station when the wind force reaches 25m / s, avoiding the problem that excessive wind force causes damage to the total station, and has better safety protection.
