Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic cylinders in coke oven mobile machinery, specifically a heat-resistant mechanism for hydraulic cylinders in coke oven mobile machinery. Background Technology

[0002] The hydraulic cylinder is the core actuator of the hydraulic system. It consists of components such as cylinder barrel, piston, piston rod, and end cap. The piston is driven to reciprocate through the pressure difference of the hydraulic oil in the sealed cavity.

[0003] In the prior art, the hydraulic cylinders in coke oven mobile machinery operate in high ambient temperatures. Typically, copper tubes are tightly wound around the outer wall of the hydraulic cylinder to form a spiral heat exchange channel. Coolant is driven by a water pump to circulate within the spiral tube, thereby dissipating heat and ensuring that the hydraulic cylinder can operate normally.

[0004] However, this heat-resistant mechanism is usually built into the hydraulic cylinder. When the spiral heat exchange channel is blocked, the heat dissipation effect will be poor, making it difficult for personnel to perform subsequent maintenance and inconvenient for personnel to use. This patent mainly addresses this issue. Therefore, we propose a heat-resistant mechanism for the hydraulic cylinder in a coke oven mobile machine. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-resistant mechanism for a hydraulic cylinder in a coke oven mobile machinery, comprising a hydraulic cylinder body, an external heat-insulating mounting shell installed on the side of the hydraulic cylinder body, and a second connecting pipe, a second connecting hose, a water supply pipe, a first connecting pipe, a first connecting hose, and a return water pipe provided on the side of the hydraulic cylinder body, wherein the second connecting pipe is connected to the second connecting hose through a pipe connection mechanism, and the other end of the second connecting hose is connected to the water supply pipe;

[0007] The outer heat-absorbing mounting shell is internally connected to an inner heat-absorbing copper pipe, a lower connecting pipe, and an upper connecting pipe.

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0028] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] Please see the appendix Figure 1 - Appendix Figure 7 This utility model discloses a heat-resistant mechanism for a hydraulic cylinder in a coke oven mobile machine, comprising a hydraulic cylinder body 1, an outer heat-insulating mounting shell 7 mounted on the side of the hydraulic cylinder body 1, and a second connecting pipe 14, a second connecting hose 13, a water supply pipe 12, a first connecting pipe 4, a first connecting hose 5, and a return water pipe 6 arranged on the side of the hydraulic cylinder body 1. The second connecting pipe 14 is connected to the second connecting hose 13 through a pipe connecting mechanism, and the other end of the second connecting hose 13 is connected to the water supply pipe 12. An inner heat-absorbing copper pipe 10, a lower connecting pipe 8, and an upper connecting pipe 11 are connected inside the outer heat-insulating mounting shell 7, and the upper connecting pipe 11 is connected to the water supply pipe 12. The upper connecting pipe 11 is connected to the inner heat-absorbing copper pipe 10. The other end of the inner heat-absorbing copper pipe 10 is connected to the lower connecting pipe 8. The lower connecting pipe 8 is connected to the return water pipe 6. The other end of the return water pipe 6 is connected to the first connecting hose 5. The other end of the first connecting hose 5 is connected to the second connecting pipe 14 through the pipe connecting mechanism. In actual use, the personnel can rotate the pipe connecting mechanism on the first connecting hose 5 and the second connecting hose 13 to disengage the first connecting hose 5 from the first connecting pipe 4 and the second connecting hose 13 from the second connecting pipe 14. The personnel can then unscrew and remove the mounting bolt 16 to remove the outer insulation mounting shell 7.

[0030] In Example 1, the external insulation mounting shell 7 is mounted on the side of the hydraulic cylinder body 1 by mounting bolts 16. A water tank 2 is connected to the side of the hydraulic cylinder body 1, and a heat dissipation pipe 3 is connected to the side of the water tank 2. One end of the heat dissipation pipe 3 is connected to the inside of the water tank 2, and the other end of the heat dissipation pipe 3 is connected to the first connecting pipe 4. By starting the water pump 15, the coolant in the water tank 2 is drawn into the second connecting pipe 14, flows into the upper connecting pipe 11 through the second connecting hose 13 and the water supply pipe 12, flows into the lower connecting pipe 8 through the upper connecting pipe 11, then flows into the first connecting pipe 4 through the return water pipe 6 and the first connecting hose 5, flows into the heat dissipation pipe 3 through the first connecting pipe 4, dissipates heat through the heat dissipation pipe 3, and finally flows back into the water tank 2. The water tank 2 on the device is provided with an inlet and an outlet, which are not shown in the figure.

[0031] A water pump 15 is connected to the side of the water tank 2. The water pump 15 is connected to the water tank 2 at the water intake end and to the second connecting pipe 14 at the water discharge end. The coolant can absorb the heat generated by flowing through the inner heat-absorbing copper pipe 10 and cool down the hydraulic cylinder body 1.

[0032] In embodiment 2, a positioning groove 17 is provided on the upper surface of the lower end of the hydraulic cylinder body 1. The positioning groove 17 has a square groove structure, and the positioning block 18 can be inserted into the positioning groove 17.

[0033] A positioning block 18 is inserted into the positioning groove 17. The positioning block 18 has a square plate structure. The positioning block 18 slides up and down along the positioning groove 17. When the positioning block 18 is slid into the positioning groove 17, the hole opened on the outer heat insulation mounting shell 7 corresponds to the threaded hole opened on the hydraulic cylinder body 1. This makes it easy for personnel to thread the mounting bolt 16 through the hole opened on the outer heat insulation mounting shell 7 and the threaded hole opened on the hydraulic cylinder body 1. This also makes it easy for personnel to install the outer heat insulation mounting shell 7 on the side of the hydraulic cylinder body 1.

[0034] The upper surface of the positioning block 18 is fixedly connected to the lower surface of the outer thermal insulation mounting shell 7. A heat-conducting block 9 is connected to the inner side of the outer thermal insulation mounting shell 7. The side of the heat-conducting block 9 is curved.

[0035] The side of the heat-conducting block 9 contacts the side of the hydraulic cylinder body 1. The inner side of the heat-conducting block 9 is connected to the inner heat-absorbing copper pipe 10. The side of the heat-conducting block 9 can contact the side of the hydraulic cylinder body 1. Heat is conducted through the heat-conducting block 9 and transferred to the inner heat-absorbing copper pipe 10. The coolant in the inner heat-absorbing copper pipe 10 carries away the heat to cool the device. At the same time, the heat-conducting block 9 can support and protect the outer heat-insulating housing 7, effectively reducing the phenomenon of deformation caused by collision of the outer heat-insulating housing 7.

[0036] Working principle:

[0037] Firstly, a heat-resistant mechanism is formed by combining water tank 2, water pump 15, second connecting pipe 14, second connecting hose 13, water supply pipe 12, upper connecting pipe 11, inner heat-absorbing copper pipe 10, lower connecting pipe 8, return water pipe 6, first connecting hose 5, first connecting pipe 4, and heat dissipation pipe 3 to achieve cooling and heat dissipation of the hydraulic cylinder body 1. By rotating the pipe connection mechanism on the first connecting hose 5 and the second connecting hose 13, the first connecting hose 5 and the first connecting pipe 4, and the second connecting hose 13 and the second connecting pipe 14, can be separated. Then, the installation bolt 16 can be loosened and removed to remove the outer insulation installation shell 7. Then, cleaning fluid can be injected into the inner heat-absorbing copper pipe 10 through the first connecting hose 5 or the second connecting hose 13 for cleaning and maintenance. Cleaning fluid can also be injected into the heat dissipation pipe 3 through the first connecting pipe 4 to clean the heat dissipation pipe 3, ensuring the heat dissipation effect of the device, improving the reliability of the device, and facilitating personnel use. At this point, the entire workflow is complete.
