Description

Technical Field

[0001] This utility model relates to the field of measurement auxiliary tools, and in particular to a multifunctional measurement auxiliary tool for underground mine roadways. Background Technology

[0002] In the mining process, accurate measurement of underground roadways is crucial for ensuring mine safety, rationally planning mining schemes, and guaranteeing the quality of roadway construction. Therefore, when conducting roadway measurements, a level instrument must be used for elevation measurement. When using a level instrument, auxiliary tools are needed to support it to ensure the accuracy and stability of the measurement.

[0003] In practical use, existing leveling instrument support tools typically feature adjustable legs for easy height adjustment. A common structure involves sliding a rod with legs onto a grooved rod, then securing the rod with legs by tightening bolts. However, when the bolts are tightened to fix the rod, the relatively small contact area between the bolt and the rod leads to significant stress concentration at the contact point. Under prolonged heavy loads or frequent assembly / disassembly operations, this stress concentration can cause localized deformation or even cracks in the rod, adversely affecting the structural integrity and lifespan of the entire device. Summary of the Invention

[0004] The purpose of this utility model is to provide a multifunctional auxiliary tool for measuring underground mine roadways, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A multifunctional auxiliary tool for measuring underground mine roadways includes a level body, which is threadedly mounted on a carrier plate. Multiple connecting pipes are connected to the bottom of the carrier plate via a rotating shaft, and support legs are slidably connected to each of the connecting pipes. The tool also includes...

[0007] A limiting component is disposed on the support leg and is used to fix the support leg at a set lifting position.

[0008] The limiting component includes a guide hole and multiple pairs of limiting holes opened inside the connecting tube. A cavity is opened on the support leg. Two pairs of connecting plates are arranged inside the cavity. A pressing piece is slidably connected to the cavity through the two pairs of connecting plates. A pair of fixing pieces that cooperate with the limiting holes are fixed on the top of the pressing piece. A return spring is also fixed inside the cavity. One end of the return spring abuts against the bottom of the pressing piece.

[0009] A button is provided on the top of the pressing plate.

[0010] The height of the button is greater than the height of the guide hole.

[0011] The button has a silicone pad on top.

[0012] The support leg is provided with multiple support plates.

[0013] The top of the connecting tube is provided with several second mounting plates evenly distributed on both sides of the guide hole, and the top of the button is provided with a pair of first mounting plates, which are parallel to the second mounting plates.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1) By setting a limiting component, the height of the support leg can be adjusted and locked securely. The operation is convenient. The elastic restoring force of the return spring makes the connection between the fixing plate and the limiting hole tighter and more secure, effectively avoiding local deformation or cracking caused by stress concentration, and improving the structural integrity and service life of the entire device.

[0016] 2) By setting up support plates, the force on the support legs is increased, thereby improving the stability of the entire device and ensuring the high stability of the device during the measurement process, preventing the measurement accuracy from being affected by accidental shaking or movement.

[0017] 3) By setting the first mounting plate and the second mounting plate, the support leg can be aligned and fixed more quickly and accurately when adjusting its height, thus improving work efficiency. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example

[0028] like Figure 1-5As shown, this utility model provides a multifunctional auxiliary tool for measuring underground mine roadways, including a carrying plate 1 and a level body 2. The level body 2 is threaded onto the carrying plate 1. Multiple connecting pipes 3 are connected to the bottom of the carrying plate 1 via a rotating shaft, and support legs 4 are slidably connected to each of the connecting pipes 3. A limiting component 100 is disposed on the support legs 4 to fix the support legs 4 at a set lifting position, ensuring the height stability of the device during measurement and preventing measurement accuracy from being affected by accidental shaking or movement. The limiting component 100 includes a guide hole 5 and multiple pairs of limiting holes 107 opened inside the connecting pipes 3. A cavity 101 is opened on the support legs 4, and two pairs of connecting plates 102 are disposed inside the cavity 101. A push button is slidably connected to the cavity 101 through the two pairs of connecting plates 102. The pressing plate 103 has a pair of fixing plates 104 fixed on its top for use with the limiting hole 107. A return spring 106 is also fixed inside the cavity 101, with one end of the return spring 106 abutting against the bottom of the pressing plate 103. A button 105 is provided on the top of the pressing plate 103. The height of the button 105 is greater than the height of the guide hole 5, allowing the button 105 to pass through the guide hole 5 and extend to the outside of the connecting tube 3 for easy operation by the operator. A silicone pad is provided on the top of the button 105, which improves the comfort of the operator and has a certain anti-slip property to prevent the operator from slipping during operation. Multiple support plates 6 are provided on the support leg 4 to increase the force on the support leg 4, thereby improving the stability of the entire device.

[0029] When using the support leg 4, to adjust its height, first press down on button 105. The button 105, under pressure, causes the pressing plate 103 to slide downwards within the cavity 101, compressing the return spring 106. The pressing plate 103 then disengages the fixing plate 104 from the limiting hole 107. At this point, the support leg 4 can be slid up and down to the desired height. Then, release button 105. The return spring 106 pushes the pressing plate 103 back to its original position, causing the pressing plate 103 to engage with the fixing plate 104 within the corresponding limiting hole 107. The support leg 4 is fixed in the set lifting position, which is convenient to operate. By utilizing the elastic restoring force of the return spring 106, the connection between the fixing plate 104 and the limiting hole 107 is more tight and stable, which effectively avoids the problem of local deformation or cracks caused by stress concentration, and improves the structural integrity and service life of the entire device. In addition to the height adjustment function, the device also has a variety of other practical functions. The level body 2 and the carrier plate 1 are connected by threads, which makes the installation and disassembly of the level body 2 more convenient and quick. Example

[0030] like Figure 6-7As shown, the difference between Embodiment 2 and Embodiment 1 is that: the top of the connecting pipe 3 is provided with several second mounting pieces 21 evenly distributed on both sides of the guide hole 5, and the top of the button 105 is provided with a pair of first mounting pieces 20. The first mounting pieces 20 and the second mounting pieces 21 are parallel. When it is necessary to adjust the height of the support leg 4, the first mounting pieces 20 and the second mounting pieces 21 are precisely aligned. At this time, the fixing piece 104 will naturally slide down to the bottom of the limiting hole 107. After releasing the button 105, the elastic force of the return spring 106 will drive the pressing piece 103 to return to its original position, thereby driving the fixing piece 104 to be tightly inserted into the limiting hole 107, thus firmly locking the height of the support leg 4.
