Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
As shown in fig. 1-8, the present invention provides an embodiment of a gravity slope gauge apparatus based on geological surveys.
Concretely, gravity slope gauge equipment based on geological survey comprises a fixing frame 1, wherein a mounting hole is formed in the fixing frame; the slope gauge body 2 is arranged in the mounting hole, the slope gauge body 2 can rotate around the axis of the mounting hole, and the slope gauge body 2 can measure the slope inclination angle of the current ground when the fixing frame 1 is placed on the ground; the fixed barrels 3 are positioned at two sides of the slope gauge body 2, and each pair of fixed barrels 3 is correspondingly connected with the two side surfaces of the fixed frame 1 one by one; the sliding columns 4 are sleeved in each fixed cylinder 3 in a one-to-one corresponding sliding manner, indication scales are arranged on the side walls of the sliding columns 4, and the sliding columns 4 can display the sliding-out length of the sliding-out fixed cylinders 3 through the indication scales;
when the slope gauge body 2 measures the slope inclination angle, a certain sliding column 4 is jacked up by the ground protrusion and slides into the corresponding fixed barrel 3.
When the fixing frame 1 is placed on the ground, one side close to the ground is the bottom end, and one side far away from the ground is the top end.
According to the invention, the early warning operation of the ground protrusion can be realized through the cooperation of the sliding column 4 and the fixed barrel 3, so that the condition that the detection data is influenced is prevented from happening because one end of the slope gauge is jacked up by the protrusion when the slope gauge is placed on the ground. When the slope gauge is specifically implemented, each sliding column 4 slides out of the corresponding fixed cylinder 3, then the fixed frame 1 is placed on the ground, so that the slope gauge body 2 measures the slope inclination angle of the current ground, when the fixed frame 1 is placed, all the sliding columns 4 are pressed on the ground, then pressure is applied to all the sliding columns 4 under the condition of ensuring the stability of the fixed frame 1, if one sliding column 4 is pressed on a protrusion, the sliding column 4 can be jacked up by the ground protrusion and slides into the corresponding fixed cylinder 3, and then the jacking quantity of the protrusion can be displayed through indication marks, so that an operator can conveniently clean or replace the measuring position.
Normally, if the ground is flat, the amount of shrinkage of each sliding column 4 is the same when the fixing frame 1 is pressed on all the sliding columns 4, but once there is a small protrusion on the ground, the operator easily ignores, so that when all the sliding columns 4 are pressed on the ground, the protrusion will lift up one sliding column 4.
Referring to fig. 1, P2 and P3 in the drawings represent bubbles, a liquid column containing the bubbles and a scale indicator, respectively, the slope gauge body 2 according to the present invention is related art, and the present invention can refer to a multifunctional slope measuring instrument in the related art when in use, and its specific working principle is as follows: when the fixing frame 1 is on the horizontal ground, the bubble is at the most central position of the liquid column (refer to fig. 1), and the pointer (the pointer comprises a rotating ring connected with the liquid column and a scale pointer arranged on the rotating ring) points to the 0 position on the scale indicating disc; when mount 1 is in the ground that has the slope, take the example of fig. 1 just if mount 1 right side is higher, the bubble is in liquid column right-hand member this moment, later rotatory swivel becket, drives the liquid column through the swivel becket and rotates for bubble in the liquid column returns central point and puts, then judges the slope through the position of scale pointer on the scale indicating plate.
Since the sliding columns 4 may have different lengths when sliding out of the fixed cylinder 3, in order to allow all the sliding columns 4 to extend out of the same length and not easily retract into the fixed cylinder 3, the sliding columns 4 and the fixed cylinder 3 are further defined: the sliding column 4 comprises a limiting section 10 and a display section 11 which are sequentially arranged along the sliding-out direction of the sliding-out fixed cylinder 3, and indication scales are arranged on the side wall of the display section 11 (the arrangement of the indication scales is shown in fig. 6);
the fixed cylinder 3 comprises an outer cylinder 5 arranged on the side wall of the fixed frame 1, and an inner cylinder 6 is sleeved in the outer cylinder 5 in a sliding manner; the limiting section 10 is sleeved in the inner cylinder 6;
an air inlet cavity is arranged between the inner cylinder 6 and the outer cylinder 5, and can store the gas injected from the outside; when the external air does not enter the air inlet cavity, the end part of the display section 11 is flush with the bottom end of the outer cylinder 5; when the external air enters the air inlet cavity, the inner cylinder 6 is pushed by the air and slides out of the outer cylinder 5 with the display section 11.
When the detection is needed, external air is directly guided to enter the air inlet cavity, then the air entering the air inlet cavity pushes the inner cylinder 6 to move towards the bottom end of the fixing frame 1, the moving inner cylinder 6 can slide out of the outer cylinder 5 with the display section 11, meanwhile, whether all the sliding columns 4 extend out of the same length can be known by judging the extending length through the indication scale, and the inner cylinder 6 cannot be easily reset due to the existence of the air.
When the gas enters the gas inlet cavity, in order to prevent the gas from flowing out of the gap between the inner cylinder 6 and the sliding column 4, the inner cylinder 6 is further limited: the inner cylinder 6 comprises a first cylinder 7 and a second cylinder 8 which slide along the inner wall of the outer cylinder 5, the second cylinder 8 is sleeved on the inner side of the first cylinder 7 in a sliding manner, the first cylinder 7 and the second cylinder 8 are respectively provided with an isolating ring 9 at one ends which are far away from each other, an air inlet cavity is positioned between the two isolating rings 9, the sliding column 4 is sleeved on the inner side of the second cylinder 8, and the inner diameter of one end of the first cylinder 7 which is far away from the second cylinder 8 is equal to the diameter of the display section 11.
When the gas enters the gas inlet cavity, the gas entering the gas inlet cavity pushes the first cylinder 7 and the second cylinder 8 away from each other, and referring to fig. 3 and 4, it can be seen that the second cylinder 8 moves towards the top end side of the fixing frame 1, the first cylinder 7 moves towards the bottom end side of the fixing frame 1, and the moving first cylinder 7 gradually slides out of the outer cylinder 5 with the display section 11.
The first cylinder 7 and the second cylinder 8 are sleeved, so that gas cannot escape from between the first cylinder 7 and the second cylinder 8, and a sealing mechanism should be arranged between the first cylinder 7 and the second cylinder 8, and the sealing mechanism can be arranged as follows (not shown in the drawings):
directly enabling one end of the first cylinder 7, which is close to the second cylinder 8, to be provided with a sealing ring groove capable of sleeving the second cylinder 8, wherein when the first cylinder 7 and the second cylinder 8 slide relatively, the second cylinder 8 slides along the sealing ring groove;
or a rubber ring sleeve which is in sealing connection with the end part of the first cylinder 7 is directly arranged at one end of the second cylinder 8, which is close to the first cylinder 7 (one end of the rubber ring sleeve is in sealing connection with one end of the second cylinder 8, which is close to the first cylinder 7, and the other end of the rubber ring sleeve is in sealing connection with one end of the first cylinder 7, which is close to the second cylinder 8), and when the second cylinder 8 slides out of the first cylinder 7, the rubber ring sleeve is gradually taken out.
The above-described two sealing methods are not limited to these two sealing methods, and the gas may not escape from between the first tube 7 and the second tube 8.
In order to prevent the sliding column 4 from sliding rapidly during sliding, the sliding column 4 is further defined as follows: the outer side wall of the limiting section 10 is provided with a clamping groove 12, a stabilizing bag sleeve 13 is sleeved in the clamping groove 12, and the stabilizing bag sleeve 13 can limit the speed of the sliding limiting section 10.
The sliding column 4 has two sliding conditions when sliding, and is jacked by the protrusion or indirectly pushed by the gas with the first cylinder 7, and in both cases, the sliding column 4 slides, so that the gas is selected to indirectly push with the first cylinder 7 for illustration.
When the moving first cylinder 7 gradually slides out of the outer cylinder 5 with the display section 11, the restriction section 10 also slides, and the sliding restriction section 10 slides along the inner wall of the second cylinder 8 with the stabilizing cuff 13 (the stabilizing cuff 13 is filled with gas), thereby restricting the sliding speed of the restriction section 10.
The bottom sliding connection of mount 1 has restriction gleitbretter 19, and restriction gleitbretter 19 can block sliding column 4.
For rapid extension operation of the slide column 4, it is preferable that: the fixing frame 1 is internally provided with a plurality of air cylinders 20, each air cylinder 20 is communicated with each pair of fixing cylinders 3, the end part of each air cylinder 20 penetrates through the bottom of the fixing frame 1 to the outer side, a piston column 21 is connected in a sliding manner in the air cylinders 20, one end, far away from the bottom of the fixing frame 1, of each piston column 21 penetrates through the fixing frame 1 to the outer side, a return piece 22 is sleeved on the side wall of one end, far away from the bottom of the fixing frame 1, of each piston column 21, the return piece 22 is located in each air cylinder 20, the piston column 21 can slide along the inner wall of each air cylinder 20 and suck external air into the fixing cylinders 3, a handle 23 is installed on one side of the bottom of the fixing frame 1, and a pair of handles 24 connected with all the piston columns 21 is arranged in the handle 23.
In this embodiment, a check valve (refer to a check valve on a vacuum compression bag in the prior art) may be disposed at the bottom of the air cylinder 20, so that only air can enter the bottom of the air cylinder 20 and no air can exit.
Once all the sliding columns 4 need to be extended, only the auxiliary handle 24 is continuously pulled, and then the movable auxiliary handle 24 drives all the piston columns 21 to slide in the air cylinder 20, when the piston columns 21 are lifted (namely, the auxiliary handle 24 is lifted), the return parts 22 are compressed, and meanwhile, the piston columns 21 pull external air into the air cylinder 20, and then the piston columns 21 are lowered (namely, the auxiliary handle 24 is released), and the return parts 22 are reset, so that the air in the air cylinder 20 is pushed into the air inlet cavity.
After knowing that there is a protrusion on the ground, the operator can choose to remove the protrusion or replace the measurement location, and the protrusion at the current location cannot be removed, and the current location is also optimal or the measurement location is chosen not to be replaced in order to speed up the measurement efficiency, so that it is preferable: the top end of the outer cylinder 5 is provided with a step pushing column 14 filled with fluid, a pushing rod 15 is sleeved in the step pushing column 14, a plurality of fluid conducting columns 16 communicated with the inside of the step pushing column 14 are arranged on the outer side of the pushing rod 15, a piston pushing column 17 is arranged in each fluid conducting column 16, and an isolating ring 9 connected with the second cylinder 8 is fixedly connected with one end of the piston pushing column 17 away from the fluid conducting column 16; excluder ring 9, connected to cartridge two 8, is movable towards step push post 14 and is slidable towards slide post 4 by fluid pushing push rod 15.
After knowing that the protrusions are present on the ground (the length of the sliding columns 4 lifted by the protrusions is recorded), all the sliding columns 4 are extended by the same length, and then the sliding columns 4 corresponding to the protrusions are locked by the restricting slide 19 (for example, the protrusions can lift up the two sliding columns 4 simultaneously), the air cylinders 20 corresponding to the two sliding columns 4 are opened simultaneously (the check valve is pushed open manually), or other air can be prevented from entering the air inlet chambers corresponding to the two sliding columns 4 temporarily.
After that, the fixing frame 1 is placed on the ground, due to the existence of the protrusions, the two sliding columns 4 tilt up against one side of the fixing frame 1, the other side tilts downwards, then, the auxiliary handle 24 is continuously lifted, the movable auxiliary handle 24 drives all the piston columns 21 to slide in the air cylinders 20, the air cylinders 20 corresponding to the two tilted sliding columns 4 are opened, so that the two sliding columns 4 cannot stretch, the air cylinders 20 corresponding to the other two sliding columns 4 can inject air into the air inlet cavities corresponding to the other two sliding columns 4, the first cylinder 7 does not move continuously along with the injection of the air (because the bottom of the outer cylinder 5 is limited), and the second cylinder 8 moves towards one side far away from the first cylinder 7.
The moving cylinder two 8 pushes all the piston pushing columns 17 to move towards the top of the outer cylinder 5 along the corresponding fluid conducting columns 16, at this time, the moving piston pushing columns 17 push the fluid (liquid or gas) in the fluid conducting columns 16 to enter the step pushing columns 14, along with the continuous entering of the fluid, the pressure increase in the step pushing columns 14 pushes the pushing rod 15 to move towards the side far away from the top of the outer cylinder 5, and then the moving pushing rod 15 pushes the other two sliding columns 4 to rise, that is, the declining side is lifted (the lifting amount is the length of the sliding column 4 lifted by the protrusion), so that the declining side is gradually close to the lifting side, the bottom of the fixing frame 1 is parallel to the ground, that is, the influence of the protrusion on gradient measurement data is reduced.
The maximum sliding amount of the first cylinder 7 is smaller than the maximum sliding amount of the pushing rod 15. The reason for this is that the movable amount of the pushing rod 15 is larger than the movable amount of the cylinder 7 with the slide column 4, and if the maximum sliding amount of the cylinder 7 is equal to (or larger than) the maximum sliding amount of the pushing rod 15, the slide column 4 is likely to be unable to be pushed again.
In order to enable the push rod 15 to extend the push rod 15 further in the first extension, it is further optimized for the push rod 15: the end of the pushing rod 15, which is close to the sliding column 4, is provided with a connecting table 18, the connecting table 18 is fixedly connected with one end of the sliding column 4, which is close to the step pushing column 14, and the diameter of the connecting table 18 is equal to the inner diameter of the second cylinder 8.
When all the sliding columns 4 extend the same length, each sliding column 4 will draw the corresponding pushing rod 15 to move the same length by the connecting table 18 at its end.
In summary, the operation flow of the invention is as follows:
the ground protrusion is first warned, and the existence position and the protrusion height of the protrusion (determined by changing the position of the sliding column 4 of the extension length) are determined.
When it is determined that the protrusion at the current position cannot be removed and the current position is also optimal or the measurement position is selected not to be replaced in order to accelerate the measurement efficiency, the lower side of the fixing frame 1 can be lifted, so that the bottom end of the fixing frame 1 is kept parallel to the ground.
The invention specifically works as follows:
each sliding column 4 is slid out of the corresponding fixed cylinder 3, namely the auxiliary handle 24 is continuously pulled, and then the movable auxiliary handle 24 drives all the piston columns 21 to slide in the air cylinder 20.
(refer to fig. 7) when the piston 21 is lifted (i.e., the lifting auxiliary handle 24), the return member 22 is compressed, and the piston 21 pulls the external air into the air cylinder 20, and then the piston 21 is lowered (i.e., the lifting auxiliary handle 24) and the return member 22 is reset, so that the air in the air cylinder 20 is pushed into the air inlet chamber.
When the gas enters the gas inlet cavity, the gas entering the gas inlet cavity pushes the first cylinder 7 and the second cylinder 8 away from each other, and referring to fig. 3 and 4, it can be seen that the second cylinder 8 moves towards the top end side of the fixing frame 1, the first cylinder 7 moves towards the bottom end side of the fixing frame 1, and the moving first cylinder 7 gradually slides out of the outer cylinder 5 with the display section 11.
Meanwhile, whether the display section 11 extends for the same length can be known by judging the extending length through the indication scale, and the inner cylinder 6 cannot be easily reset due to the existence of gas.
Then, place mount 1 on ground again, make slope rule body 2 measure the slope inclination on current ground, and when mount 1 is placed, all slip post 4 can press subaerial earlier, afterwards, exert pressure to all slip post 4 under the circumstances of guaranteeing mount 1 stability, if certain slip post 4 has pressed on the protrusion, so this slip post 4 can be jacked and slide into corresponding fixed barrel 3 by ground protrusion, afterwards alright show the jacking volume of protrusion through the instruction scale, make things convenient for the operator clean or change the measurement position.
Normally, if the ground is flat, the amount of shrinkage of each sliding column 4 is the same when the fixing frame 1 is pressed on all the sliding columns 4, but once there is a small protrusion on the ground, the operator easily ignores, so that when all the sliding columns 4 are pressed on the ground, the protrusion will lift up one sliding column 4.
When it is known that the protrusions are present on the ground (the length of the slide columns 4 lifted by the protrusions is recorded), all the slide columns 4 are extended by the same length (the slide columns 4 are extended again after the reset), and then the slide columns 4 corresponding to the protrusions are locked by the restricting slide 19 (for example, the protrusions can lift up the two slide columns 4 at the same time), and the air cylinders 20 corresponding to the two slide columns 4 are opened at the same time (the check valve can be manually pushed open).
After that, the fixing frame 1 is placed on the ground, due to the existence of the protrusions, the two sliding columns 4 tilt up against one side of the fixing frame 1, the other side tilts downwards, then, the auxiliary handle 24 is continuously lifted, the movable auxiliary handle 24 drives all the piston columns 21 to slide in the air cylinders 20, the air cylinders 20 corresponding to the two tilted sliding columns 4 are opened, so that the two sliding columns 4 cannot stretch, the air cylinders 20 corresponding to the other two sliding columns 4 can inject air into the air inlet cavities corresponding to the other two sliding columns 4, the first cylinder 7 does not move continuously along with the injection of the air (because the bottom of the outer cylinder 5 is limited), and the second cylinder 8 moves towards one side far away from the first cylinder 7.
The moving cylinder two 8 pushes all the piston pushing columns 17 to move towards the top of the outer cylinder 5 along the corresponding fluid conducting columns 16, at this time, the moving piston pushing columns 17 push the fluid (liquid or gas) in the fluid conducting columns 16 to enter the step pushing columns 14, along with the continuous entering of the fluid, the pressure increase in the step pushing columns 14 pushes the pushing rod 15 to move towards the side far away from the top of the outer cylinder 5, and then the moving pushing rod 15 pushes the other two sliding columns 4 to rise, that is, the declining side is lifted (the lifting amount is the length of the sliding column 4 lifted by the protrusion), so that the declining side is gradually close to the lifting side to enable the bottom of the fixing frame 1 to be parallel to the ground, that is, the influence of the protrusion on gradient measurement data is reduced.
Operation of resetting the extended slide column 4:
all the check valves are opened to discharge the gas in the gas cylinder 20 and the gas in the gas inlet cavity, then the sliding column 4 is manually pushed to reset until the bottom end of the sliding column 4 is flush with the bottom end of the outer cylinder 5, and when the sliding column 4 is reset, the pushing rod 15 is pushed to reset, for example, as shown in fig. 4, when the pushing rod 15 rises, the pressure in the step pushing column 14 is increased, so that the fluid conducting column 16 is entered and the piston pushing column 17 in the fluid conducting column 16 is pushed to reset, and the reset piston pushing column 17 pushes the second cylinder 8 to move towards one side of the first cylinder 7, and then the first cylinder 7 is pushed to move towards the second cylinder 8 by an auxiliary device such as a wood rod until the state shown in fig. 1 is shown.
Compared with the prior art, the improvement points of the invention are as follows:
according to the invention, the early warning operation of the ground protrusion can be realized through the cooperation of the sliding column 4 and the fixed barrel 3, so that the condition that the detection data is influenced is prevented from happening because one end of the slope gauge is jacked up by the protrusion when the slope gauge is placed on the ground.
According to the invention, through the cooperation of the piston pushing column 17 and the pushing rod 15, when the fixing frame 1 is placed on the ground, the declining side of the fixing frame 1 can be gradually close to the tilting side, so that the bottom of the fixing frame 1 is parallel to the ground, that is, the influence of the protrusions on gradient measurement data is reduced.
