Description

Technical Field

[0001] This utility model relates to the field of well depth measurement technology, specifically to an auxiliary device for measurement. Background Technology

[0002] Well depth measurement technology can ensure a precise geometric connection between surface and underground measurements, allowing both the surface and underground to use the same plane coordinate system and elevation system, thereby ensuring the safety and accuracy of mining engineering. However, existing measurement devices are inconvenient, and the steel wire used for measurement is cut off directly from the top after the measurement is completed, wasting a lot of steel wire.

[0003] To ensure user safety during readings, facilitate accurate measurements, and avoid waste by recycling the steel wire, utility model patent CN215109038U discloses a connecting measuring device, including a base with an inverted L-shaped bracket mounted on the upper part; an upper telescopic frame mounted on the upper part of the bracket, and a lower telescopic frame mounted on the lower part of the bracket; a measuring part is provided at the lower part of the connecting measuring device, which can rotate through the base after being fixed; it is fixed and positioned by two points: a pulley and a positioning wheel. However, this connecting measuring device is relatively cumbersome to install, requires a flat surface at the location of use, and is inconvenient to use with the steel wire and steel ruler. Therefore, it is essential to design an auxiliary device for connecting measurements that is easy to install, convenient to operate during measurement, and facilitates user readings after the steel wire is inserted. Utility Model Content

[0004] To address the technical problems existing in the background art, the present invention provides an auxiliary device for measurement.

[0005] The technical solution of this utility model is as follows: An auxiliary device for measurement, comprising a tripod and a measuring device, wherein the measuring device includes a wire box, a steel ruler box, and a mounting block.

[0006] The tripod includes a ring disc with a central opening and three telescopic legs.

[0007] The telescopic foot includes a telescopically connected first bracket and a second bracket. The first bracket consists of two parallel square rods and a connecting rod at the bottom. The top end is rotatably connected to an annular disk. One of the parallel square rods has a through groove on its upper surface along the length direction that opens away from the center of the annular disk. One end of the second bracket passes through the connecting rod and enters between the two parallel square rods, and can be locked in any position.

[0008] The three telescopic feet are designated as the first telescopic foot, the second telescopic foot, and the third telescopic foot.

[0009] A wire box is fixed to the lower outer surface of the first bracket of the first telescopic leg. The end of the wire in the wire box is detachably connected to the mounting block. The wire and the mounting block can pass through the central hole of the annular disk along the groove.

[0010] A steel ruler box is rotatably connected to the outer side of the lower end of the first bracket of the second telescopic leg, and a viewing window is provided on the outer side of the steel ruler box.

[0011] The groove cross-section is designed to be arc-shaped, so that when the steel wire passes through the groove, it is at the lowest point of the groove and its position is fixed.

[0012] Preferably, the groove cross-section can also be designed as a V-shaped opening groove, with the opening direction being away from the center of the annular disk.

[0013] The measuring device also includes a turntable, and the steel ruler box is rotatably connected to the first support via the turntable.

[0014] Furthermore, the turntable is also equipped with scale numbers, and the rotation angle can be read after the steel ruler box rotates. The steel ruler can be fixed on the turntable after rotation, and the axis of the steel ruler box and the turntable coincides and is perpendicular to the upper surface of the second telescopic foot.

[0015] The wire outlet on the wire box is aligned with the groove on the telescopic foot, and the wire is stretched along the groove.

[0016] The auxiliary device for measurement also includes a counterweight. The counterweight is installed on the outer surface of the first bracket of the third telescopic foot. The counterweight is installed at the same height as the steel ruler box, and its weight is the same as that of the steel wire box, ensuring the stability of the overall device.

[0017] The central opening of the annular disc is a vertical opening, which allows the steel wire to hang vertically and shortens the path, thus saving steel wire material.

[0018] As a preferred option, a pulley can also be designed in the center hole of the annular disc to make the wire stretching smoother and reduce friction with the annular disc.

[0019] Both the wire box and the ruler box are cylindrical. Furthermore, both the wire box and the ruler box are designed with a braking device and a winding device. When the wire or ruler is stretched to the desired length, it can be fixed. After the measurement is completed, the winding device can retract the wire or ruler without the need for manual winding.

[0020] The tripod's three telescopic legs are set at equal angles on the outer ring of the circular disc, ensuring the stability of the entire device.

[0021] Through the above design, the beneficial effects of this utility model's auxiliary device for measurement are as follows:

[0022] Reduce waste and save costs. The steel wire can be freely extended and retracted, and only unsafe or problematic steel wires are cut off, thus saving costs.

[0023] The tripod is collapsible, saving on transportation costs, making installation easier, use safer, and allowing for easy reading.

[0024] Steel rulers offer greater flexibility, overcome limitations, and are suitable for a wider range of work scenarios. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Figure 1 This diagram illustrates the overall structure of an auxiliary device for measurement, including Embodiment 1 of the present invention.

[0035] An auxiliary device for measurement consists of a tripod and a measuring device, the measuring device including a wire box 6, a steel ruler box 7, and a mounting block 11;

[0036] The tripod includes a circular disc 1 with a central opening and three telescopic legs, such as Figure 2 ;

[0037] The telescopic foot includes a first bracket 2 and a second bracket 4 that are telescopically connected. The first bracket 2 consists of two parallel square rods and a connecting rod at the bottom. The top end is rotatably connected to the annular disk 1. One of the parallel square rods has a through groove 3 that opens away from the center of the annular disk 1 along its length on its upper surface. One end of the second bracket 4 passes through the connecting rod and enters between the two parallel square rods, and can be locked in any position.

[0038] Combination Figure 3 The diagram shows that the three telescopic feet are the first telescopic foot 12, the second telescopic foot 13, and the third telescopic foot 14; a wire box 6 is fixed to the lower outer surface of the first bracket 2 of the first telescopic foot 12, and the end of the wire 10 in the wire box 6 is detachably connected to the hanging block 11, such as... Figure 5 As shown, the steel wire 10 and the mounting block 11 can pass through the central hole of the annular disk 1 along the groove 3;

[0039] A steel ruler box 7 is rotatably connected to the outer side of the lower end of the first bracket 2 of the second telescopic foot 13, and a viewing window 8 is provided on the outer side of the steel ruler box 7.

[0040] The top of the first support 2 of the telescopic legs is rotatably connected to the ring disk 1. When the tripod is in use, the telescopic legs are set at a certain angle to the ground. When the measurement is completed, the three telescopic legs can be retracted to be perpendicular to the ground, and the second support 4 slides into the first support 2, saving the overall placement space required for the device.

[0041] The tripod's three telescopic legs are set at equal angles on the outer ring of the circular disk 1, ensuring the entire device is stable under force. The first and second supports are of equal length, allowing the tripod to be retracted to save space after measurement.

[0042] The center opening of the tripod's ring disc 1 is a vertical opening, which allows the steel wire 10 and the hanging block 11 to hang vertically, and shortens the path, saving material on the steel wire 10.

[0043] Preferably, a pulley can be installed in the center hole of the annular disk 1 to make the steel wire 10 stretch more smoothly and reduce friction with the annular disk 1.

[0044] As a further preferred option, the shape of the central hole of the annular disk 1 is not fixed and can be designed to be any shape that facilitates the passage of the steel wire 10 and the mounting block 11.

[0045] The auxiliary device for measurement also includes a counterweight 5, which is installed on the outer surface of the first bracket 2 of the third telescopic foot 14. The counterweight 5 is installed at the same height as the steel ruler box 7, and the weight of the counterweight 5 is the same as the weight of the steel wire box 6, ensuring the stability of the overall device.

[0046] The measuring device also includes a turntable 9. Figure 4 The positional relationship between the steel ruler, turntable 9, and second telescopic foot 13 is given. The steel ruler box 7 and the first bracket 2 are rotatably connected through the turntable 9.

[0047] Furthermore, the turntable 9 is also equipped with scale numbers. The rotation angle can be read after the steel ruler box 7 rotates, and the steel ruler can be fixed on the turntable 9 after rotation. The axes of the steel ruler box 7 and the turntable 9 coincide and are perpendicular to the upper surface of the second telescopic foot 13.

[0048] Both the wire box 6 and the steel ruler box 7 are cylindrical. Furthermore, both the wire box 6 and the steel ruler box 7 are designed with a braking device and a winding device. When the wire 10 and the steel ruler are stretched to the target length, the wire 10 and the steel ruler can be fixed. After the measurement is completed, the winding device can retract the wire 10 and the steel ruler without the need for manual winding.

[0049] Furthermore, the steel ruler inside the steel ruler box 7 is designed with a device for connecting the hanging block 11 at the end. The width of the steel ruler is smaller than the diameter of the central opening of the annular disk 1. The steel ruler can be connected to the hanging block 11 and pass through the central opening of the annular disk 1 vertically downward.

[0050] The outlet of the wire 10 on the wire box 6 is aligned with the groove 3 on the telescopic foot. The wire 10 is stretched along the groove 3, saving the distance between the wire and the groove. The steel ruler box 7 is designed in the same way, and this design makes the distance between the steel ruler and the groove 3 fixed. During measurement, if the steel ruler needs to enter the location to be measured, the data read by the viewing window 8 is recorded. Subtracting the length of the first bracket 2 and the annular width of the annular disk 1, the data of the location to be measured can be obtained.

[0051] The groove 3 is designed with an arc shape so that when the steel wire 10 passes through the groove 3, it is at the lowest point of the groove 3 and its position is fixed.

[0052] Preferably, the cross-section of the groove 3 can also be designed as a V-shaped opening groove 3, with the opening direction being away from the center of the annular disk 1.

[0053] The specific usage method of this device is as follows: First, the tripod is supported at the position to be measured. The end of the steel wire 10 is fixed together with the hanging block 11 and dropped into the center hole of the annular disk 1. The wire is dropped vertically downward along the side of the center hole to the location to be measured. The braking device of the steel wire box 6 fixes the steel wire 10. The steel ruler in the steel ruler box 7 is operated in the same way. The measurement data is read from the viewing window 8. Second, the braking device releases the steel wire 10, and the winding device retracts the steel wire 10 into the steel wire box 6. The steel ruler box 7 is operated in the same way. Finally, the tripod is put away to proceed to the next step.

[0054] Through the above design, the beneficial effects of this utility model's auxiliary device for measurement are as follows:

[0055] To reduce waste and save costs, the steel wire 10 can be freely extended and retracted, and only unsafe or problematic steel wire 10 is cut off, thus saving costs.

[0056] The tripod is collapsible, saving on transportation costs, making installation easier, use safer, and allowing for easy reading.

[0057] Steel rulers offer greater flexibility, overcome limitations, and are suitable for a wider range of work scenarios.
