[0039] The present application embodiment provides an encoder and a cable protection device, referring to Figure 1 and Figure 2 , Figure 1The overall structure diagram of the encoder and cable protection device is shown. Figure 2 Shows Figure 1 The encoder and cable protection device includes: a support component 1, a protection component 2 and an auxiliary component 3; wherein the support component 1 is installed on the iron mouth opening machine 4 at a position corresponding to the encoder 5, the support component 1 has a receiving space 13, and the encoder 5 is placed in the receiving space 13; the support component 1 is provided with an avoidance space 12, and the protection component 2 is placed in the avoidance space 12 at a position corresponding to the encoder 5; the protection component 2 has a switching structure, which can be switched according to different scenes to protect the encoder 5; the auxiliary component 3 is connected to the support component 1, and cooperates with the protection component 2 to protect the encoder 5; the auxiliary component 3 is provided with a protection structure adapted to the cable to protect the cable.

[0040] Exemplarily, the support assembly 1 can be detachably mounted on the taphole opening machine 4 by means of bolts, etc. This arrangement facilitates the removal of the support assembly 1 and parts such as the encoder 5 from the taphole opening machine 4.

[0041] As another example, the support assembly 1 may be installed on the outside of the encoder 5 . For example, the support assembly 1 may be a box body, a shell, or other parts to protect the encoder 5 .

[0042] Exemplarily, the protection component 2 may be disposed in the support component 1, and the encoder 5 is protected by the protection component 2. For example, the protection component 2 may include a cold water pipe, and the temperature around the encoder 5 is cooled by circulating cold water, thereby reducing the probability of the encoder 5 failing due to high temperature, and thus protecting the encoder 5.

[0043] As another example, a switching structure may be further provided on the protection component 2 , for example, the degree of cooling of the encoder 5 may be adaptively adjusted according to different ambient temperatures, thereby further improving the protection effect on the encoder 5 .

[0044] Exemplarily, the encoder cable 51 or other component cables may be protected by the auxiliary component 3 , for example, by providing a protective sleeve around the cable.

[0045] As another example, the encoder 5, the encoder cable 51 or cables of other parts may be cooled by passing cooling air.

[0046] In the above embodiment, since a support component 1 is provided, the support component 1 can provide protection for the encoder 5 and provide an installation environment for other parts; since a protection component 2 is provided, the encoder 5 is protected by the protection component 2, and the structure can be switched according to different scenarios to improve the protection effect of the encoder 5; since an auxiliary component 3 is provided, the protection effect of the encoder 5 can be further improved by the auxiliary component 3, and the component cables can be protected.

[0047] In some embodiments of the present application, reference Figure 3 and Figure 4 , Figure 3 Shows Figure 1 View of the middle part in the direction of B, Figure 4 Shows Figure 3 The support assembly 1 includes a support member 11, the support member 11 has a receiving space 13, the support member 11 and the tap hole opening machine 4 are respectively provided with a first connection structure and a second connection structure that match each other, and the support member 11 is connected to the tap hole opening machine 4 through the first connection structure and the second connection structure.

[0048] In an embodiment of the present application, the support assembly 1 can be configured to have a structural form including a support member 11, the support member 11 can be provided with a accommodating space 13, a first connecting structure can be provided on the support member 11, the iron mouth opening machine 4 can be provided with a second connecting structure, and the support member 11 is installed on the iron mouth opening machine 4 via the first connecting structure and the second connecting structure.

[0049] It can be understood that the encoder 5 is installed on the opposite side of the driving motor 6 on the iron mouth opening machine 4. The encoder 5 can transmit the rotation value of the driving motor 6 to the electronic control system 39 through the connecting cable fixed on the iron mouth opening machine 4, and convert it into the depth value of the iron mouth opening machine 4 through the electronic control system 39 and programming.

[0050] Exemplarily, the support member 11 may be provided with a threaded hole, and a position on the taphole opening machine 4 corresponding to the support member 11 may also be provided with a threaded hole, and the support member 11 may be mounted on the taphole opening machine 4 through the threaded hole and bolts.

[0051] As another example, the support member 11 can be configured to include an inner support portion 112 and an outer support portion 111. For example, the inner support portion 112 can be an inner sleeve, and the two ends of the inner sleeve are detachably connected with cover plates, and a sealed accommodating space 13 is formed in the inner sleeve. The outer support portion 111 can be an outer sleeve, and the outer sleeve is sleeved on the outside of the inner sleeve, and the axes of the outer sleeve and the inner sleeve can coincide, or nearly coincide. The inner sleeve can be connected to the inner side wall of the outer sleeve by a connecting rod, and the connecting rod is not marked in the figure. On the one hand, it is convenient to fix the inner sleeve, and on the other hand, it does not affect the flow of water in the avoidance space. Closing plates are detachably installed at both ends of the outer sleeve, so that a sealed avoidance space 12 can be formed between the outer side wall of the inner sleeve and the inner side wall of the outer sleeve.

[0052] Among them, installation points or installation structures can be set on the inner side of the inner sleeve, and the encoder 5 or other parts can be installed in the inner sleeve through these points or structures.

[0053] In the above embodiment, since the internal support portion 112 is provided, the internal support portion 112 can provide an installation environment for the encoder 5 or other components, and isolate the encoder 5 from the protective structure to reduce the probability of damage to the encoder 5; since the external support portion 111 is provided, the external support portion 111 can provide an installation environment for the protective component 2 and the auxiliary component 3, and the structure is simple and easy to assemble.

[0054] In some embodiments of the present application, reference Figure 5 and Figure 6 , Figure 5 The figure shows the connection structure of the water inlet pipe 21, the water return pipe 22 and the support member 11. Figure 6 Shows Figure 5 Internal structure diagram. Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the protection component 2 includes an inlet pipe 21 and a return pipe 22. The inlet pipe 21 is arranged in the avoidance space 12. The inlet pipe 21 located in the avoidance space 12 is arranged around the inner support part 112. The inlet pipe 21 is connected to the water circulation system, and the return pipe 22 is connected to the water circulation system.

[0055] Exemplarily, the protection component 2 can be configured to include a water inlet pipe 21 and a water return pipe 22. For example, a water circulation system is provided on the iron mouth opening machine 4 or other positions corresponding to the iron mouth opening machine 4, and the water circulation system is connected with the water inlet pipe 21 and the water return pipe 22. Cold water enters the water inlet pipe 21 from the water circulation system, passes through the inner support part 112 and the outer support part 111, and then flows back to the water circulation system from the water return pipe 22, and the cycle continues.

[0056] The water inlet pipe 21 in the avoidance space 12 can be spirally wound around the inner support portion 112. This arrangement can better cool the area around the inner support portion 112, and no other structure is required to support the water inlet pipe 21. One end of the return pipe 22 can also be set at a corresponding position in the avoidance space 12.

[0057] In the above embodiment, since the water inlet pipe 21 and the water return pipe 22 are provided, cold water is transported through the water inlet pipe 21 and the water return pipe 22 to cool the surroundings of the inner support part 112 and the outer support part 111, thereby reducing the temperature around the encoder 5 and protecting the encoder 5.

[0058] In some embodiments of the present application, reference Figure 7 , Figure 8 , Fig. 9 and Fig.10 , Figure 7 It shows a cross-sectional view of the water inlet pipe 21, the water return pipe 22, and the support member 11. Figure 8 Shows Figure 7 The enlarged view of the structure at II in the middle. Fig. 9 Shows Figure 7 The enlarged view of the structure at III in the middle. Fig.10 FIG. 2 shows a structural diagram of a portion of the water inlet pipe 21 located in the first switching member 23. Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the protection component 2 also includes a first switching component 23 and a second switching component 24, and the first switching component 23 and the second switching component 24 both have a connecting structure; the first switching component 23 and the second switching component 24 are both arranged in the avoidance space 12, and the first switching component 23 and the second switching component 24 are both connected to the outer support part 111, and along the water inlet direction, the first switching component 23 and the second switching component 24 are respectively arranged at both ends of the inner support part 112.

[0059] Exemplarily, the protection component 2 may be configured to include a first switching member 23 and a second switching member 24. For example, the first switching member 23 may be a first connection block, which is hollow inside; the second switching member 24 may be a second connection block, which is hollow inside. Along the water inlet direction, that is, along the axial direction of the inner support portion 112, the first connection block and the second connection block are respectively arranged at the location areas of the two ports of the inner support portion 112.

[0060] Among them, along the axial direction of the inner support part 112, the water inlet pipe 21 can pass through the first switching member 23, and the water inlet pipe 21 can move, for example, rotate, in the first switching member 23; the connection between the water inlet pipe 21 and the first switching member 23 has good sealing performance. Taking the first switching member 23 as an example, the first connection block can be provided with a first notch 211 on the circumference of the water inlet pipe 21 arranged in the first connection block, and the side wall of the first connection block can be provided with a second notch 231, and the size of the second notch 231 can match the size of the first notch 211.

[0061] It can be understood that the position of the first notch 211 can be close to the inner bottom surface of the first connecting block. It is configured so that when the first notch 211 and the second notch 231 are not aligned, the first notch 211 can be close to the inner bottom surface of the first connecting block, and the first notch 211 is blocked by the inner bottom surface of the first connecting block, so that water can flow into the second switching component 24 through the water inlet pipe 21. During this process, water will not enter the first switching component 23 or a small amount of water will enter the first switching component 23.

[0062] It should be explained that the water inlet pipe 21 in the first switching member 23 can be set to a partially raised structure, that is, the inner diameter of the water inlet pipe 21 in the first switching member 23 can be different; and a sealing member with elastic function, such as a sealing strip, sealing cotton, etc., can be set at a position corresponding to the first notch 211 on the inner bottom surface of the first switching member 23, as long as it does not affect the rotation of the water inlet pipe 21 in the first switching member 23. In this way, when the first notch 211 and the second notch 231 are not aligned, the probability of water leakage in the water inlet pipe 21 can be reduced.

[0063] In another example, the second switching member 24 is a second connection block. The end of the water inlet pipe 21 away from the first switching member 23 can be inserted into the second connection block, and the water inlet pipe 21 can rotate in the second connection block, and there is good sealing between the water inlet pipe 21 and the second connection block. One end of the return pipe 22 is inserted into the second connection block, and there is a good seal between the return pipe 22 and the second connection block. The water flow entering the second connection block through the water inlet pipe 21 can enter the return pipe 22 and then flow back to the water circulation system.

[0064] In addition, a water outlet 212 is provided around the water inlet pipe 21 in the second connection block, and the water flow in the water inlet pipe 21 in the second connection block can enter the second connection block through the water outlet 212. A water inlet 241 is provided around the second connection block, and the water flow in the avoidance space 12 can enter the second connection block through the water inlet 241. A baffle 213 is detachably connected to the water inlet pipe 21 in the second connection block. For example, the baffle 213 can be sleeved on the water inlet pipe 21. When the water inlet pipe 21 is subjected to a force, the baffle 213 can be driven to rotate. The size of the baffle 213 can be the same as the size of the water inlet 241. When the baffle 213 is in contact with the water inlet 241, the baffle 213 blocks the water inlet 241, and the water flow in the avoidance space 12 will not enter the second connecting block; when the baffle 213 is offset from the water inlet 241, the water flow in the avoidance space 12 can enter the second connecting block and flow back to the water circulation system through the return pipe 22.

[0065] In the above embodiment, since the first switching member 23 and the second switching member 24 are provided, when the ambient temperature continues to rise, the first switching member 23 and the second switching member 24 can allow water to flow into the avoidance space 12, directly cool down the inner support portion 112, and then cool down the area around the encoder 5, thereby improving the cooling effect.

[0066] In some embodiments of the present application, Figure 5 and Figure 7 As shown, the port of the water inlet pipe 21 located in the second switching member 24 is connected to a blocking member 25, the outer support portion 111 is connected to a driving member 26, the output shaft of the driving member 26 is inserted into the outer support portion 111 and the two are rotationally connected, and the output shaft of the driving member 26 is connected to the blocking member 25.

[0067] For example, the second switching member 24 is a second connection block. A blocking member 25 may be connected to the port of the water inlet pipe 21 in the second switching member 24, that is, the water in the water inlet pipe 21 does not flow out from the port, but flows out from the water outlet 212 on the side of the water inlet pipe 21 to the second connection block. The blocking member 25 may be a blocking block, a blocking plate or other parts that can achieve a sealing effect.

[0068] In another example, a driving member 26 may be provided at a position corresponding to the outer support portion 111, the iron mouth opening machine 4 or other second switching member 24. For example, the driving member 26 may be a motor, and the axial direction of the motor output shaft may be parallel to, or nearly parallel to, the axial direction of the outer support portion 111. The motor output shaft may be inserted into the outer support portion 111, and the motor output shaft may be able to rotate on the outer support portion 111; the motor output shaft may be connected to the blocking member 25, and the blocking member 25 may be driven to rotate by the motor output shaft, thereby driving the water inlet pipe 21 and the baffle 213 to rotate.

[0069] In the above embodiment, since the blocking member 25 is provided, the blocking member 25 provides an installation point for the driving member 26, which facilitates the connection between the driving member 26 and the water inlet pipe 21; since the driving member 26 is provided, the driving member 26 can drive the water inlet pipe 21 to move and switch the mode without manual operation, which is flexible and convenient.

[0070] In some embodiments of the present application, reference Fig.11 and Fig.12 , Fig.11 The structure diagram of auxiliary component 3 is shown. Fig.12 The cross-sectional view of the encoder cable 51, the temperature sensor cable 371, the covering member 33, and the auxiliary member 31 is shown. Figure 1 , Figure 4 , Fig.11 and Fig.12 As shown, the auxiliary component 3 includes an auxiliary part 31, which is installed on the iron mouth opening machine 4 at a position corresponding to the encoder 5, and the auxiliary part 31 is provided with a ventilation structure 32, and the encoder cable 51 is provided with a covering part 33, and the covering part 33 passes through the auxiliary part 31; the auxiliary part 31 is provided with an air inlet 34 and an air outlet 35, and the air outlet 35 is connected to a cooling air pipe 36, and the cooling air pipe 36 is inserted into the outer support part 111 and the inner support part 112.

[0071] Exemplarily, the auxiliary component 3 can be configured to include an auxiliary part 31. For example, the auxiliary part 31 can be an external protective tube, which can be mounted on the tapping machine 4 by means of a tube clamp 7 or other means, and the middle of the external protective tube can be configured to be a hollow structure so that other parts can be mounted in the external protective tube.

[0072] The outer protective tube is also penetrated by a sheath 33. For example, the sheath 33 may be an inner protective tube, that is, the inner protective tube penetrates the outer protective tube, and part of the structure of the inner protective tube is located in the outer protective tube. The encoder cable 51 may be inserted into the inner protective tube, and the encoder cable 51 may be protected by the inner protective tube. The inner protective tube may be made of high temperature resistant material to reduce the probability of being damaged by iron filings. In the embodiment of the present application, there is no specific restriction on the materials of the outer protective tube and the inner protective tube.

[0073] In addition, the external protective tube is provided with an air inlet 34 and an air outlet 35. The air inlet 34 can be connected to an air inlet pipe, and the air outlet 35 can be connected to a cooling air pipe 36.

[0075] In some embodiments of the present application, Figure 1 , Figure 4 , Fig.11 and Fig.12 As shown, a temperature sensor 37 is arranged at a position corresponding to the encoder 5 in the accommodating space 13, the temperature sensor cable 371 is covered by the covering member 33, an electromagnetic switch valve 38 is installed at the air inlet 34, and the encoder cable 51, the temperature sensor cable 371, and the electromagnetic switch valve cable 381 are connected to the electronic control system 39.

[0076] Exemplarily, a temperature sensor 37 can be arranged in the accommodating space 13, that is, the temperature sensor 37 can be installed on the inner wall of the inner support portion 112. The temperature sensor cable 371 can pass through the inner support portion 112 and the outer support portion 111 to enter the covering member 33 and be covered by the covering member 33; the encoder cable 51 can also pass through the inner support portion 112 and the outer support portion 111.

[0078] In the above embodiment, since a temperature sensor 37 is provided, the environment around the encoder 5 can be monitored through the temperature sensor 37, so that timely measures can be taken to reduce the probability of damage to the encoder 5; since an electromagnetic switch valve 38 and an electronic control system 39 are provided; the electromagnetic switch valve 38 and the electronic control system 39 can control the input of the cooling gas, and the encoder 5 is cooled by the cooling gas, thereby improving the cooling effect on the encoder 5.

[0079] The following is an explanation of the use of the encoder 5 provided by the present application, i.e., the cable protection device. When in use:

[0080] S100: First, the water circulation system is started, and the cold water in the water circulation system enters the second switching member 24 through the water outlet 212 on the water inlet pipe 21. At this time, the first notch 211 on the first switching member 23 is not aligned with the second notch 231, that is, the first switching member 23 blocks the first notch 211, and the cold water in the water inlet pipe 21 will not enter the avoidance space 12 through the second notch 231. After the cold water enters the second switching member 24, the baffle 213 blocks the water inlet 241, and the cold water flowing from the water inlet pipe 21 to the second switching member 24 enters the water circulation system through the return pipe 22; this goes back and forth, and the encoder 5 is cooled by setting a circulating water flow in the water inlet pipe 21 wound around the inner support part 112.

[0081] S200: When the ambient temperature continues to rise, the driving member 26 is started, the driving member 26 drives the blocking member 25 to rotate, the blocking member 25 drives the water inlet pipe 21 to rotate, the water inlet pipe 21 drives the baffle 213 to rotate, the baffle 213 is staggered with the water inlet 241, and the first notch 211 and the second notch 231 are aligned, the cold water in the water inlet pipe 21 can enter the first switching member 23 and the avoidance space 12, the water flow in the avoidance space 12 enters the second switching member 24 through the water inlet 241 on the second switching member 24, and the second switching member 24 The water flow on the upper side can enter the water circulation system through the return pipe 22; the avoidance space 12 can also be connected to a water storage component, and the cooling effect on the environment around the encoder 5 is improved by adding flowing water in the avoidance space 12; when the temperature drops to the set temperature, the driving member 26 drives the blocking member 25 to rotate in the opposite direction, and the blocking member 25 drives the water inlet pipe 21 to rotate, the baffle 213 blocks the water inlet 241, and the first notch 211 and the second notch 231 will not be aligned, and the cold water in the water inlet pipe 21 will not enter the accommodating space 13, and the cycle is repeated.

[0082] S300: When the temperature measurement system detects that the temperature near the encoder 5 rises and exceeds the set temperature, the encoder 5 cable transmits a signal to the electronic control system 39, and the electronic control system 39 controls the electromagnetic switch valve 38 to start through the electromagnetic switch valve cable 381, and the cooling air enters the auxiliary part 31 through the air inlet 34, and the cooling air cools the covering part 33, and then cools the encoder cable 51 and the temperature sensor cable 371. The cooling air in the auxiliary part 31 enters the accommodating space 13 through the air outlet 35 to cool the encoder 5 and the temperature sensor 37. An exhaust pipe can be inserted in the accommodating space 13, and the exhaust pipe is not drawn in the figure. The exhaust pipe passes through the inner support part 112 and the outer support part 111. The end of the exhaust pipe away from the encoder 5 can be set in the outside to facilitate the discharge of the cooling gas in the accommodating space 13. There is good sealing between the exhaust pipe and the inner support part 112, and there is good sealing between the exhaust pipe and the outer support part 111. The connections between the inner support portion 112 , the outer support portion 111 , and the avoidance space 12 involved in this application should all meet the sealing requirements to reduce the probability of water leakage in the avoidance space 12 .
