Description

Technical Field

[0001] The invention belongs to the technical field of die casting transportation, and in particular relates to a monitoring wiring clamping hardware. Background Art

[0002] Wiring clamps: mainly used to organize disorderly cables or wires, avoid entanglement, squeezing and crossing of wires, reduce short circuits, short circuits and overloads caused by local overheating, and thus avoid fires; at the same time, reduce the incidence of electric shock and leakage accidents caused by damage to wires due to disorderly distribution; through the arrangement of wiring devices, wires with different functions can be classified and placed, which is convenient for quick identification and implementation of corresponding maintenance work when needed, and can make the line layout clearer and more beautiful;

[0003] In addition, when different types of cables (such as power lines, signal lines or data lines, etc.) are close to each other, electromagnetic interference will be generated between them, affecting the stable transmission of information and even causing the corresponding transmission chain to collapse; disorderly cables not only have the problem of occupying a large space, but also increase the probability of mechanical damage to a certain extent, and increase the signal transmission cost;

[0004] However, traditional clamping tools are exposed to the external environment for a long time, so the external temperature, humidity and impurities such as acidity and alkalinity in the air constantly interact with each other on the outer surface. For example, temperature changes constantly affect the elastic modulus of the material, that is, when the temperature rises, the elastic modulus of the material decreases, the elastic deformation ability increases, and the material expands until a gap appears between the material connection ends; when the temperature drops, the elastic modulus of the material increases, the elastic deformation ability of the material decreases, and the material connection ends are prone to fracture, deformation and dislocation.

[0005] During this process, the shape, size and structure between the inner surface of the clamp and the outer surface of the cable change accordingly due to thermal expansion and contraction. That is, the friction between the clamp and the working surface of the cable changes under the influence of temperature, and even sticks to each other. In addition, acidic and alkaline impurities in the air are prone to chemical reactions with the working surface of the material, which promotes corrosion. Corrosion products will gradually fill the gaps between the working surfaces, increase the difficulty of opening and closing in the later stage, affect the disassembly of the clamp by maintenance personnel in the later stage, and further affect the maintenance and rearrangement of the cable.

[0006] At the same time, there are problems of position invariance and singleness between the interacting working surfaces of the traditional clamping tool and the cable, that is, after the clamping tool completes the clamping, its working surface can only clamp a specific area of ​​the outer wall of the cable, and the position remains unchanged. Over time, residual stress will continue to accumulate between the clamping tool and the cable working surface, leading to stress concentration, until an irregular connection appears between the clamping tool and the cable working surface, increasing the difficulty of opening and closing. Summary of the invention

[0043] The lossless transposition wiring method of different types of cables uses the above-mentioned monitoring wiring clamping hardware to implement clamping wiring. The specific steps are as follows:

[0044] S1: First, the telescopic gas rod drives the horizontal axis under the guiding limit of the clamping tooling, and synchronously controls the three-point gear, the four-point gear and the six-point gear in different areas to move away from the end of the telescopic gas rod until the three-point gear, the four-point gear or the six-point gear is meshed with the driven gear at the corresponding position;

[0045] S2: Then, the winches in different areas are driven to move successively through the meshing action between the same three-part gear, four-part gear or six-part gear and the driven gear in different areas. In the specific implementation, the angles between the midline of the gear area of ​​the three-part gear, four-part gear or six-part gear in different areas and the horizontal axis are different;

[0046] S3: Finally, during the rotation of the capstan, the sub-rotation frame is synchronously moved. After that, under the guidance of the sub-rotation frame and the support of the column, the strips drive the pie wheels in different directions to approach or move away from the axial end of the shaft disc at the same time until the pie wheels collide with the outer surface of the cable.

[0047] The present invention has the following beneficial effects:

[0048] 1. The present invention promotes the mutual meshing of the three-part gear, the four-part gear or the six-part gear with the driven gear at different positions through the rotation of the horizontal axis. After that, the capstans at different positions drive the sub-rotation frame to rotate successively. In this process, the strips drive the pie wheel to approach or move away from the axial end of the shaft disk under the dual effects of the sub-rotation frame guide limit and the column support positioning until the pie wheel conflicts with the outer surface of the cable to be clamped, thereby realizing the alternating and stable clamping of different areas of the outer surface of the cable to be clamped by the pie wheels at different positions, fully ensuring the interaction force between the pie wheel and the cable, avoiding the stress concentration problem between the pie wheel and the working surface of the cable in a long-term temperature change environment, reducing the difficulty of disassembly of the clamping tooling by the later maintenance personnel, and improving the maintenance efficiency.

[0049] 2. The present invention controls the right-angle plate to move toward the axial end of the ring rail through the clamping plate until the scraper contacts the outer surface of the cable and the inner wall of the T-tube. After that, the scraper is driven to continuously interact with the outer surface of the cable under the guidance of the ring rail through the table plate. At the same time, the cleaning liquid in the water tank is guided to the scraper and cable working area through the water pipe, so as to improve the cleaning ability of the scraper, fully ensure the cleanliness of the connection end between the cable and the clamping tooling, reduce contact resistance, avoid the occurrence of local overheating, improve the stable transmission of current, create a stable and uniform electric field distribution, and reduce the possibility of arc discharge; in addition, cleaning helps to reduce the wear between the cable and the cake wheel or the clamping tooling, improve the fit between the cable and the clamping working surface, increase the clamping force, and extend the service life of the cable and corresponding components.

[0050] 3. The present invention controls the electric telescopic rod through the square shell to drive the arc plate to move to the designated area away from the clamping tooling before the low temperature comes. After that, the arc plates are driven to move toward each other through the two electric telescopic rods that are oppositely distributed until the cable is clamped to a certain height. At this time, the cable part between the cable and the T-tube is in a non-stretched state, so as to buffer the result of the straightening and breaking caused by the contraction of the outer surface of the cable in the low temperature environment, that is, to provide the cable with a contraction buffer margin in the low temperature environment, improve the material resistance of the cable in the low temperature environment, and reduce the maintenance cost.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0073] It should be noted that the terms “vertical”, “horizontal”, “left”, “right” and similar expressions used in this document are only for the purpose of explanation and do not represent the only implementation method.

[0074] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0075] Reference Figure 1 , Figure 3 and Figure 4 It can be seen that a monitoring wiring clamping hardware includes a clamping tool 1, which is composed of an upper shell 11 and a lower shell 12. A limit unit 2 is arranged inside the clamping tool 1, and adjustment units 3 are symmetrically arranged at both ends of the clamping tool. A cleaning unit 4 is arranged on one side of the adjustment unit 3.

[0077] The shaft disc 26 is mounted on the end face of the chassis 21 close to the column 23; the vertical rods 27 are grouped into three and are evenly distributed in the circumferential direction on the end face of the shaft disc 26 away from the chassis 21; in addition, the vertical rods 27 and the shaft disc 26 are mounted in a snap-fit ​​manner; the capstan 28 is mounted in a snap-fit ​​manner on the end of the three vertical rods 27 in the same group away from the chassis 21; the sub-rotating frames 29 are grouped into three and are evenly distributed in the circumferential direction on the capstan 28; in addition, the sub-rotating frames 29 are mounted in a rotational manner with the capstan 28 through the rotating shaft, and the sub-rotating frames 29 are mounted in a sliding snap-fit ​​manner with the strip 24;

[0078] Reference Figure 5 , Figure 6 , Figure 7 and Figure 8It can be seen that a driven gear 291 is mounted on the outer wall of the capstan 28, a pancake wheel 292 is mounted on the end of the strip 24 away from the column 23 through a rotating shaft, a telescopic gas rod 293 is mounted on the inner wall of the vertical section on one side of the clamping fixture 1, and a horizontal shaft 294 is mounted on the end of the telescopic gas rod 293 near the middle position of the clamping fixture 1, and the horizontal shaft 294 passes through the outer wall of one side of the chassis 21. In addition, the end of the horizontal shaft 294 away from the telescopic gas rod 293 is slidably mounted between the vertical section of the clamping fixture 1 away from the telescopic gas rod 293, and the outer wall of the horizontal shaft 294 is sequentially mounted with a three-point gear 295, a four-point gear 296 and a six-point gear 297, and a single three-point gear 295, a four-point gear 296 and a six-point gear 297 are a group. In addition, the number and position correspond one to one with the chassis 21.

[0079] Reference Figure 1 and Figure 2 It can be seen that the clamping tool 1 is composed of an upper shell 11 and a lower shell 12, the cross-sectional shape of the upper shell 11 and the lower shell 12 is T-shaped, a heat dissipation pad 13 is clamped and installed between the upper shell 11 and the lower shell 12 to seal the upper shell 11 and the lower shell 12, and key plates 14 are symmetrically arranged on the outer walls of the vertical sections on both sides of the upper shell 11 and the lower shell 12, and the key plates 14 are detachably installed with the upper shell 11 and the lower shell 12 by bolts;

[0080] The angle between the midline of the gear area of ​​the three-part gear 295 and the axis of the horizontal axis 294 is ninety degrees, the angle between the midline of the gear area of ​​the four-part gear 296 and the axis of the horizontal axis 294 is one hundred and twenty degrees, and the angle between the midline of the gear area of ​​the six-part gear 297 and the axis of the horizontal axis 294 is one hundred and eighty degrees. The thickness of the three-part gear 295, the four-part gear 296 and the six-part gear 297 are all less than the thickness of the driven gear 291. In addition, the distances between the three-part gear 295, the four-part gear 296 and the six-part gear 297 are equal, and the vertical distance between the three-part gear 295 and the four-part gear 296 or the four-part gear 296 and the six-part gear 297 is greater than the thickness of the driven gear 291; the height of the sub-rotation frame 29 is less than the vertical distance between the capstan 28 and the coaxial disk 26.

[0081] The clamping tool 1 is assembled by splicing the upper shell 11, the lower shell 12, the heat dissipation pad 13 and the key plate 14 for the following purposes:

[0082] First, the clamping connection between the upper shell 11 and the lower shell 12 facilitates the later maintenance personnel to perform maintenance and maintenance on the internal limit unit 2, and also facilitates the later maintenance personnel to perform rapid maintenance on one of the cables, thereby reducing maintenance costs and improving maintenance efficiency;

[0083] Secondly, a heat dissipation pad 13 is filled between the upper shell 11 and the lower shell 12. On the one hand, it can avoid the possibility of impurities being deposited inside the gap between the clamping tool 1 when the clamping tool 1 expands and contracts due to heat, reduce the corresponding residual stress accumulation, and improve the regularity and firmness of the connection between the two. On the other hand, it helps to improve the heat dissipation effect between the upper shell 11 and the lower shell 12 and reduce the local concentration of heat inside the clamping tool 1.

[0084] Finally, by the movable disassembly of the key plate 14, the connection stability between the upper and lower shells 12 is further improved, and it is convenient for the later maintenance personnel to disassemble and assemble;

[0085] The specific limiting process of the limit unit 2 on the cable is taken as an example of the cable model corresponding to the three-part gear 295:

[0086] First, the telescopic gas rod 293 controls the horizontal axis 294 to drive the three-way gear 295 to move away from the telescopic gas rod 293. In the extended state, the gas is compressed in the area between the piston and the bottom of the outer tube. At this time, the pressure of the gas acts on the piston, which makes the inner tube remain in the extended position. In the contracted state, the inner tube contracts inward under the action of external force, the piston compresses the gas, and the gas pressure increases. When it is implemented specifically, it can be driven by an external drive device.

[0087] Until the three-part gears 295 at different positions are in positive relative distribution with the driven gear 291 at the same time, a plurality of three-part gears 295 are evenly distributed at different positions on the outer wall of the horizontal axis 294, and the number and position of the three-part gears 295 correspond to the number and position of the driven gear 291 one by one. In addition, when the three-part gears 295 are in positive relative distribution with the driven gear 291 at the corresponding position, since the angles between the midline of the gear area of ​​the three-part gears 295 at different positions and the axis of the horizontal axis 294 are different, the meshing time of the three-part gears 295 at different positions and the driven gear 291 during rotation is sequential. In order to improve the rationality of the layout, a two-by-two cross-type symmetrical distribution layout is adopted. For details, please refer to the attached Figure 5 In the a, b, c and d areas, that is, a is a group with c, and b is a group with d, the meshing time between the three-part gear 295 in the a and c areas and the driven gear 291 at the corresponding position is consistent, and similarly, the meshing time between the three-part gear 295 in the b and d areas and the driven gear 291 at the corresponding position is consistent, but there is a sequence of meshing times between the three-part gear 295 in the a and c and the b and d areas and the driven gear 291, and thereafter, the meshing between the three-part gear 295 in the a and c and the b and d areas and the driven gear 291 at the corresponding position is alternating reciprocating meshing until the cable model changes;

[0088] Next, the capstan 28 is controlled by the driven gear 291. In specific implementation, the built-in motor can be used to drive the horizontal shaft 294 to rotate, thereby ensuring the meshing between the three-part gear 295 and the driven gear 291, and synchronously driving the sub-rotation frame 29 to rotate. In this process, the shaft disc 26 is driven by the vertical rod 27 to synchronously follow the capstan 28 to rotate;

[0089] Finally, when the sub-rotating frame 29 rotates, the strip plate 24 is forced to drive the pancake wheel 292 to approach or move away from the axial end of the chassis 21 under the support and positioning effect of the column 23, until the pancake wheel 292 contacts the outer surface of the cable, and the pancake wheels 292 arranged at multiple angles clamp the cable at the same time, reducing the contact area of ​​the clamping working surface while fully ensuring the clamping stability;

[0090] It is hereby explained that when the three-dividing gears 295 at different positions are out of meshing area with the driven gear 291 at the corresponding position, the column 23, under the restoring action of the torsion spring 25, prompts the strip 24 to apply a reverse force to the sub-rotation frame 29 until the capstan 28 returns to the initial position, thereby ensuring the long-term effectiveness of the alternate clamping scheme of the pie wheels 292 at different areas on the outer surface of the cable;

[0091] The four-point gear 296 and the six-point gear 297 are the basis for the implementation of other types of cables, and it should be understood that the three-point gear 295, the four-point gear 296 and the six-point gear 297 are only references for specific implementation plans. In specific implementation, more detailed and reasonable divisions can be made. In addition, the movement of the four-point gear 296 or the six-point gear 297 can be achieved by controlling the movement of the horizontal axis 294 through the telescopic gas rod 293, which helps to quickly achieve the clamping of different models and reduce the clamping cost;

[0092] It is hereby explained that the number of teeth of the three-part gear 295, the four-part gear 296 and the six-part gear 297 decreases in a descending manner. The specific meshing areas can be referred to in the attached Fig.13 Middle D, E and F areas.

[0093] Reference Figure 1 , Figure 4 , Fig.11 and Fig.12 It can be seen that the adjustment unit 3 includes: a T-joint 31, which is mounted in the middle of the outer walls of the two sides of the vertical section of the clamping fixture 1, and is perpendicular to the key plate 14; two end plates 32, which are symmetrically mounted in the middle of the outer walls of the two ends of the clamping fixture 1; in addition, the cross-sectional shape of the end plate 32 is concave; an angle seat 33, which is symmetrically mounted on the end surface of the end plate 32 close to the middle of the clamping fixture 1, and the angle seat 33 matches the receiving groove 15; a ring rail 34, which is mounted in the end of the angle seat 33 away from the middle of the clamping fixture 1, and the ring rail 34 is half a semicircle;

[0094] The table plate 35 is slidably mounted on the middle position of the end face of the ring rail 34 away from the clamping fixture 1; the ear seat 36 is mounted on the middle position of the end of the table plate 35 away from the axis of the ring rail 34; the spring rod 37 is plugged and installed in the middle position of the ear seat 36; the clamping plate 38 is slidably mounted on the middle position of the end face of the table plate 35 away from the clamping fixture 1, and the clamping plate 38 and the spring rod 37 are mounted in a clamping manner; the right-angle plate 39 is mounted on the middle position of the end face of the clamping plate 38 away from the table plate 35.

[0095] Reference Figure 5 and Fig.14 It can be seen that a cooling fan 321 is provided in the middle position of one side end plate 32, and a filter cartridge 322 which is mounted on the same end plate 32 is snap-fitted and installed at one end of the cooling fan 321 close to the end plate 32, and an air duct 323 which penetrates the end plate 32 is snap-fitted and installed at one end of the filter cartridge 322 away from the cooling fan 321, and the air duct 323 is located inside the clamping fixture 1, and an air ring 324 which is coaxially arranged with the chassis 21 is snap-fitted and installed at one end of the air duct 323 away from the filter cartridge 322, and the cross-sectional shape of the air ring 324 is an isosceles trapezoid, in addition, the diameter of the air ring 324 at one end close to the corner seat 33 is smaller than the diameter of the air ring 324 at one end away from the corner seat 33, and wind tunnels 325 are evenly opened at one end of the air ring 324 close to the corner seat 33.

[0096] Reference Figure 1 , Fig.10 , Fig.11 and Fig.12 It can be seen that the cleaning unit 4 includes: an air pump 41, which is clamped and installed on the outer walls of the vertical sections of the two right-angle plates 39 at the position of one end plate 32; an air valve 42, which is symmetrically clamped and installed on the end surfaces of the horizontal section of the right-angle plate 39, and the positions of the air valve 42 and the air pump 41 correspond one to one; a water diversion pipe 43, which is clamped and installed on the outer walls of the vertical sections of the two bracket plates at the position of the other end plate 32; a scraper 44, which is symmetrically clamped and installed on the end surfaces of the horizontal section of the right-angle plate 39, and the positions of the scraper 44 and the water diversion pipe 43 correspond one to one;

[0097] There are two square shells 45, which are symmetrically snap-fitted and installed between two opposite end plates 32; in addition, the square shell 45 is snap-fitted and installed with the corner seat 33 through a connecting plate; two electric telescopic rods 46 form a group, and are symmetrically snap-fitted and installed at the middle position of the inner wall of the horizontal section of the square shell 45; the arc plate 47 is snap-fitted and installed at the end of the electric telescopic rod 46 away from the end plate 32; the water storage tank 48 is snap-fitted and installed on the end surface of the end plate 32 away from the clamping tool 1 through a buckle;

[0098] The square shell 45 is assembled from two parts, the length of the air valve 42 and the scraper 44 is greater than the length of the arc plate 47, the length of the horizontal section of the angle seat 33 is consistent with the width of the square shell 45, the inner diameter of the ring rail 34 is greater than the inner diameter of the T-tube 31, and the upper shell 11 and the lower shell 12 are symmetrically provided with storage grooves 15 at one end away from the heat dissipation pad 13.

[0099] The specific adjustment process of the adjustment unit 3 to the position of the right angle plate 39 is as follows:

[0100] First, the angle seat 33 drives the ring rail 34 to move closer to or away from the T-joint pipe 31, so as to adjust the vertical distance between the ring rail 34 and the clamping fixture 1. In specific implementation, the angle seat 33 can be driven to move by an electric slider;

[0101] Next, the ear seat 36, under the control of the table 35, synchronously drives the spring rod 37 to drive the clamping plate 38 to rotate with the axis of the ring track 34 as the center point. In specific implementation, the table 35 can be driven by an electric slider to continuously rotate under the guidance of the ring track 34. The specific rotation speed can be provided by external experimental data.

[0102] Finally, the clamping plate 38 drives the right angle plate 39 to move toward or away from the axis end of the T-tube 31 until the end of the scraper 44 close to the axis of the ring rail 34 conflicts with the outer surface of the cable and the end of the scraper 44 away from the axis of the ring rail 34 conflicts with the inner wall of the T-tube 31, and the aforementioned scraper 44 conflicts with the cable at the corresponding position or the inner wall of the T-tube 31. Specific implementation process: First, the clamping plate 38 drives the right angle plate 39 to move toward one side of the axis of the ring rail 34, at which time the spring rod 37 is stretched. In specific implementation, the clamping plate can be driven by an electric slider 38 moves. When the scraper 44 contacts the cable, the scraper 44 is driven to move toward the T-tube 31 through the angle seat 33. Thereafter, the clamping plate 38 drives the right-angle plate 39 to move away from the axial end of the ring rail 34 until the scraper 44 on one side contacts the inner wall of the T-tube 31 while the scraper 44 on the other side still contacts the cable. The spring rod 37 is stretched a certain distance, but not beyond the elastic coefficient range. Therefore, after falling back a certain distance, the scraper 44 near the axial end of the ring rail 34 and the outer surface of the cable still maintain a certain interaction force.

[0103] The specific cleaning process of the cleaning unit 4 on the outer surface of the cable and the inner wall of the T-tube 31 is as follows:

[0104] When the scraper 44 contacts the T-tube 31 and the cable at the same time, the cleaning liquid stored in the water tank 48 is gradually guided to the working area of ​​the scraper 44, the cable and the inner wall of the T-tube 31 through the water guide pipe 43. In specific implementation, the cleaning liquid in the water tank 48 can be guided to the water guide pipe 43 through an external pump. Thereafter, the scraper 44 synchronously follows the rotation of the table 35 to perform the dual operations of scraping and cleaning the outer surface of the cable and the inner wall of the T-tube 31, thereby fully ensuring the cleanliness of the outer surface of the cable and the inner wall of the T-tube 31, alleviating the problems of local overheating and stress concentration, and the outer wall of the cable contacts the end surface of the inner wall of the T-tube 31;

[0105] The working principle of the air valve 42 is basically the same as that of the scraper 44. In specific implementation, the air pump 41 can be used to deliver high-pressure gas into the air valve 42. Only the implementation method and effect are different. That is, through the blowing effect of the air valve 42, the inner wall of the T-joint pipe 31 and the outer surface of the cable after being cleaned by the scraper 44 are quickly dried, and the local overheating problem at the junction of the two is further alleviated. The clamping process and time of the arc plate 47 on the outer wall of the cable in a low temperature environment:

[0106] The square shell 45 controls the electric telescopic rod 46 to drive the arc plate 47 to move away from the clamping tool 1 to the designated area before the low temperature comes. In specific implementation, the movement of the square shell 45 is realized by the angle seat 33. Thereafter, the arc plates 47 are driven to move toward each other by the two electric telescopic rods 46 that are oppositely distributed, until the cable is clamped to a certain height, and at this time, the cable portion between the cable and the T-tube 31 is in a non-straightened state, so as to buffer the result of the cable outer surface shrinking in the low temperature environment, causing the straightening and breaking, that is, providing the cable with a shrinkage buffer margin in the low temperature environment, improving the material resistance of the cable in the low temperature environment, and reducing the maintenance cost;

[0107] The air ring 324 blocks the external gas at the connection end of the clamping fixture 1 and the T-tube 31, and discharges the gas in the clamping fixture 1. The heat dissipation fan 321 guides the external gas to the filter cartridge 322, and the clean gas in the filter cartridge 322 is guided to the air ring 324 through the air duct 323, and blown to the outside of the clamping fixture 1 through the wind tunnel 325, so as to ensure the internal operating temperature of the clamping fixture 1, to a certain extent curb the thermal expansion and contraction, and reduce the difficulty of opening and closing the clamping fixture 1 in the later stage. In specific implementation, a filter net is arranged inside the filter cartridge 322 to avoid the possibility of impurities in the air entering the clamping fixture 1, thereby isolating the acidic and alkaline impurities in the air from corroding the limit unit 2 and the cable end face.

[0108] The working principle of a monitoring wiring clamping hardware provided by the present invention is as follows: the first step is to first drive the horizontal shaft 294 through the telescopic gas rod 293 under the guiding and limiting action of the clamping tool 1, and synchronously control the three-point gear 295, the four-point gear 296 and the six-point gear 297 in different areas to move away from one end of the telescopic gas rod 293 until the three-point gear 295 or the four-point gear 296 or the six-point gear 297 is meshed with the driven gear 291 at the corresponding position;

[0109] In the second step, the capstan 28 in different areas are driven to move successively through the meshing action between the same three-part gear 295, four-part gear 296 or six-part gear 297 and the driven gear 291. In the specific implementation, the angles between the midline of the gear area of ​​the three-part gear 295, four-part gear 296 or six-part gear 297 in different areas and the horizontal axis 294 are different;

[0110] In the third step, the capstan 28 rotates to synchronously cause the sub-rotation frame 29 to move. After that, the slats 24, under the guidance of the sub-rotation frame 29 and the support of the column 23, drive the pie wheels 292 in different directions to approach or move away from the axial end of the shaft disc 26 at the same time until the pie wheels 292 collide with the outer surface of the cable.

[0111] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
