Description

Technical Field

[0001] The utility model relates to the technical field of delamination instrument detection, and more specifically, to a fixing device for a coal mine delamination instrument. In addition, it also relates to a delamination instrument assembly including the fixing device for a coal mine delamination instrument. Background Art

[0002] In the prior art, many coal mines require that the delamination meter 4 has a preset initial value after installation. However, the common method is to install the delamination meter 4 on the coal seam roof 9 of the coal mine to monitor the delamination of the roof coal seam using the delamination meter 4. The installation diagram is as follows: Figure 1 As shown, the support plate 8 of the delamination meter 4 is close to the coal seam roof 9, so the initial value of the delamination meter 4 installed on the coal seam roof 9 is always 0, which does not meet the current use requirements of the coal mine. Among them, the coal mine requires the delamination meter 4 to have a non-zero initial value in order to verify whether the delamination meter 4 is installed firmly and reliably. Therefore, after the delamination meter 4 is installed, it is necessary to pull down the fixing tube 2 of the delamination meter 4. If the fixing tube 2 is pulled to have an indication (initial value), it can be determined that the delamination meter 4 is installed properly and the anchor claw 3 is firmly fixed in the anchor hole 6 and is not loose. If the fixing tube 2 is pulled without an indication (initial value), it means that the anchor claw 3 is not firmly anchored in the anchor hole 6 and is loose, and then it is judged that the installation of the delamination meter 4 has failed, and it is necessary to re-drill and re-install.

[0003] In summary, how to make the delamination instrument have a preset initial value to meet the use requirements of certain coal mines is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The core of the utility model is to provide a fixing device for a coal mine delamination instrument, which can make the delamination instrument have a preset initial value to meet the use requirements of certain coal mines, and the device has a simple structure and is easy to use, and can be promoted for use. Another core of the utility model is to provide a delamination instrument assembly including the above-mentioned fixing device for a coal mine delamination instrument.

[0029] Please refer to Figures 2 to 4 .

[0030] This specific embodiment provides a fixing device for a coal mine delamination instrument, which is applied to the delamination instrument 4 and includes: a fixing member 1 clamped on the outer periphery of a fixing tube 2 of the delamination instrument 4, and the fixing member 1 and the fixing tube 2 are interference-fitted to limit the position of the fixing tube 2.

[0031] It should be noted that the delamination meter 4 is a special monitoring instrument for monitoring the movement of the roof rock layer. The delamination meter 4 is also called the roof delamination meter, which is also called the roof delamination indicator, and can effectively ensure the safe production of coal mines. In actual use, the shape, structure, material, size, etc. of the fixing part 1 can be determined according to actual conditions and actual needs.

[0032] It should also be noted that the present device is applied to the delamination meter 4 in order to make the delamination meter 4 have a preset initial value, and the initial value is not 0. The delamination meter 4 has a preset initial value because the mine needs to verify whether the delamination meter 4 is installed firmly and reliably. Therefore, after the delamination meter 4 and other components are installed, the fixing tube 2 needs to be pulled down. When the fixing tube 2 is pulled, there is still an indication (initial value), which means that the installation of the anchor claw 3 in the anchor hole 6 is fine, and the anchor claw 3 is firmly fixed in the anchor hole 6 and is not loose. If there is no indication (initial value) when the fixing tube 2 is pulled, it means that the anchor claw 3 is not firmly fixed in the anchor hole 6 and the anchor claw 3 is loose, that is, the installation of the delamination meter 4 fails, and it is necessary to re-drill and re-install a set of delamination meters 4. By installing the fixing part 1 on the fixing tube 2, it can be ensured that the delamination meter 4 has an indication, which makes it easier to judge the fixing condition of the anchor claw 3.

[0033] When using the fixing device for coal mine separation meter provided by the utility model, since the fixing device for coal mine separation meter is applied to the separation meter 4, the separation meter 4 needs to be installed first. First, the anchor claw 3 is sent to the deep of the anchor hole 6 by the top rod and fixed by the barb, then the top rod is taken out, and then the fixing tube 2 of the separation meter 4 is inserted into the anchor hole 6, and the wire rope 5 connected with the anchor claw 3 is hung down and passed through the through hole of the fixing tube 2, and then the wire rope 5 can be tightened, and the wire rope 5 is connected to the sensor inside the separation meter 4 to complete the assembly operation of the separation meter 4.

[0034] Subsequently, the fixed tube 2 can be pulled downward to a preset distance (which is the preset initial value of the delamination meter 4), and the fixing part 1 of the fixing device for the coal mine delamination meter can be sleeved on the outer periphery of the fixed tube 2. The fixing part 1 and the fixed tube 2 have an interference fit, which can effectively limit the position of the fixed tube 2 and prevent the fixed tube 2 from retracting into the anchor hole 6 under the pulling force of the wire rope 5 after the operator removes the pulling force. That is, by using the fixing part 1, it can be effectively ensured that the fixed tube 2 moves to the preset position and will not move again, so that the delamination meter 4 has the required initial value.

[0035] In summary, the fixing device for the coal mine delamination meter provided by the utility model can make the delamination meter 4 have a preset initial value to meet the use requirements of certain coal mines, and the device has a simple structure and is easy to use, and can be promoted for use.

[0036] In one embodiment, the fixing member 1 includes a first plate 11 for clamping with the multi-toothed rubber sleeve 7 on the fixing tube 2 and a second plate 12 for hand-held operation. The first plate 11 is provided with a U-shaped notch, and the second plate 12 is distributed along the axial direction of the central axis of the U-shaped notch. The structure is as follows Figure 4 shown.

[0037] It should be noted that the outer periphery of the fixing tube 2 and the anchor hole 6 are clamped and fixed by a soft multi-toothed rubber sleeve 7. When the force is small, the fixing tube 2 will not be displaced under the action of the multi-toothed rubber sleeve 7, but when the force is large, the multi-toothed rubber sleeve 7 cannot effectively fix the fixing tube 2, that is, the multi-toothed rubber sleeve 7 is mainly used to preliminarily fix the fixing tube 2 at a certain position of the anchor hole 6. If it is necessary to ensure that the position of the fixing tube 2 is not easily changed, it is necessary to use the fixing piece 1 in conjunction.

[0038] When the fixing member 1 is needed to fasten the fixing tube 2 at a certain position, the operator can hold the second plate 12 to insert the first plate 11 into the multi-tooth rubber sleeve 7. The position of the fixing tube 2 can be effectively fixed through the interference fit between the first plate 11 and the multi-tooth rubber sleeve 7.

[0039] In one embodiment, the first plate 11 and the second plate 12 are an integrated structure to ensure the structural stability of the fixing member 1, avoid the first plate 11 and the second plate 12 from being separated due to excessive force during use, and reduce the assembly process of the device.

[0040] In one embodiment, the first plate 11 and the second plate 12 are both metal plates or plastic plates to ensure that when the first plate 11 is inserted into the outer periphery of the multi-toothed rubber sleeve 7, the first plate 11 and the second plate 12 are not damaged or deformed, and the hard metal plate or plastic plate and the soft multi-toothed rubber sleeve 7 have an interference fit to ensure the assembly and fixing effect of the two.

[0041] In one embodiment, the U-shaped notch includes a first notch 13, a second notch 14 and a third notch 15 distributed in a semicircular shape, the first notch 13, the second notch 14 and the third notch 15 are connected in sequence, the second notch 14 includes two parallel straight sections, the diameter of the third notch 15 is less than or equal to the minimum outer diameter of the multi-tooth rubber sleeve 7, and the structure is as follows: Figure 4 The size of the first notch 13 is larger than that of the second notch 14, which makes it easier to fit the second notch 14 and the third notch 15 on the outer periphery of the multi-toothed rubber sleeve 7, so that the third notch 15 is tightly fitted on the outer periphery of the multi-toothed rubber sleeve 7.

[0042] In one embodiment, the thickness of the first plate 11 is less than or equal to the pitch height of the multi-pronged rubber sleeve 7. Therefore, during use, if the preset initial value needs to be changed, the second plate 12 can be pulled outward by hand, so that the first notch 13 and the outer periphery of the multi-pronged rubber sleeve 7 are in contact, so as to move the first plate 11 up and down, so that the first plate 11 and the multi-pronged rubber sleeve 7 at different height positions are clamped and fixed, and when the fixed cylinder 2 moves to a new preset position, the second plate 12 is pushed again, so that the third notch 15 is tightly sleeved on the outer periphery of the multi-pronged rubber sleeve 7, so as to re-fix the fixed cylinder 2, so that the delamination instrument 4 has a new initial value.

[0043] In one embodiment, the fixing member 1 includes two semi-circular ring-shaped snap rings, which are fixed by snapping to form a circular ring structure, and the circular ring structure is used to snap with the multi-toothed rubber sleeve 7 of the fixing tube 2. That is, the fixing tube 2 can be pulled down by a preset distance, and then the two snap rings are set on the outer periphery of the multi-toothed rubber sleeve 7 of the fixing tube 2. Finally, the two semi-circular ring-shaped snap rings are snap-fitted and fixed, so that the position of the fixing tube 2 is effectively fixed by the snap rings to achieve the desired preset initial value. In actual use, the shape, structure, material, size, etc. of the fixing member 1 can be determined according to actual conditions and actual needs to effectively fix the fixing tube 2 and facilitate manufacturing and use.

[0044] In addition to the above-mentioned fixing device for coal mine delamination instrument, the utility model also provides a delamination instrument assembly including the fixing device for coal mine delamination instrument disclosed in the above-mentioned embodiment, the structure of which is as follows: Figure 2 and Figure 3 shown.

[0045] The delamination meter assembly is applied to the delamination meter 4, which includes the delamination meter 4, the anchor claw 3, the wire rope 5 and any one of the above-mentioned fixing devices for the delamination meter in coal mines. The anchor claw 3 is fixed in the anchor hole 6, the fixing tube 2 of the delamination meter 4 is inserted into the anchor hole 6, one end of the wire rope 5 is connected to the anchor claw 3, and the other end of the wire rope 5 passes through the fixing tube 2 and is connected to the sensor of the delamination meter 4; the outer periphery of the fixing tube 2 is sleeved with a multi-toothed rubber sleeve 7 for clamping with the anchor hole 6, a preset distance is provided between the support plate 8 of the delamination meter 4 and the coal seam roof 9, and the fixing part 1 of the fixing device for the delamination meter in coal mines is sleeved on the multi-toothed rubber sleeve 7, and the fixing part 1 is against the coal seam roof 9. Please refer to the prior art for the structures of other parts of the delamination meter assembly, which will not be described in detail herein.

[0046] In order to further illustrate the use process of the delamination instrument assembly provided by the utility model, an example is given below.

[0047] First, the anchor claw 3 can be sent to the deepest part of the anchor hole 6 through the mandrel, and the anchor claw 3 can be fixed in the anchor hole 6 by the barb, then the mandrel is taken out, and then the fixing tube 2 of the delamination instrument 4 can be put into the anchor hole 6, and the wire rope 5 connected with the anchor claw 3 at one end is hung down and passed through the through hole of the fixing tube 2, and the other end of the wire rope 5 is extended into the fixing tube 2 until it is connected with the sensor of the delamination instrument 4, so as to tighten the wire rope 5, and then, the multi-toothed rubber sleeve 7 can be set on the outer periphery of the fixing tube 2, so as to use the multi-toothed rubber sleeve 7 to preliminarily fix the fixing tube 2 at a certain position of the anchor hole 6, and then, the fixing tube 2 can be pulled outward by a certain distance according to the required initial value, so that the support plate 8 of the delamination instrument 4 is no longer close to the coal seam roof 9, at this time, the fixing part 1 (for example, the operator holds the second plate 12 to clamp the first plate 11 on the multi-toothed rubber sleeve 7) can be clamped on the multi-toothed rubber sleeve 7, so as to prevent the fixing from retracting into the anchor hole 6, thereby ensuring the stability of the initial value of the delamination instrument 4. During use, if the coal seam sinks or breaks, it will cause the wire rope 5 to move, and transmit the changes to the sensor in real time, so that the delamination instrument 4 can accurately detect the changes in the coal seam.

[0048] It should be noted that the first plate 11 and the second plate 12, the first notch 13 and the second notch 14 and the third notch 15 mentioned in the present invention, wherein the first, second and third are only used to distinguish the different positions, and there is no order of precedence.
