Description

Technical Field

[0001] This utility model relates to the technical field of pile driver accessories, specifically to an impact-resistant pile head base for a pile driver. Background Technology

[0002] When a pile driver is in use, its pile head is subjected to tremendous force. Therefore, after working for a period of time, there will be residual internal stress inside the pile head. This internal stress will prevent the pile driver from continuing to operate and will also easily cause cracks inside the pile head, thereby reducing the life of the pile head.

[0003] To extend the lifespan of pile heads, improve their impact resistance, and improve their overall lifespan, it is necessary to eliminate internal stress after each use. This can be achieved through heat treatment, allowing the pile head to cool down, or manually vibrating it. However, in practice, due to the large size of the pile head and its suspended position, heat treatment and vibration are difficult to implement, and allowing it to cool down requires a considerable amount of time. Therefore, a new type of pile head base is needed to address this issue. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model proposes an impact-resistant pile head base for pile drivers, which can cool the pile head by spraying water, and the water temperature can gradually change from high temperature to low temperature during the process, thereby effectively reducing the internal stress of the pile head, extending the service life of the pile head, preventing internal cracks, and maintaining its impact resistance.

[0005] The technical solution to achieve the purpose of this utility model is as follows: an impact-resistant pile head base for a pile driver, including a connecting column, a base fixedly connected to the connecting column, a cooling component provided on the connecting column, the cooling component including a shell, a housing, a water pump, a solenoid valve, a water pipe and a bottom hole, the shell being disposed on the connecting column, two housings being fixedly connected to the shell, two water pumps being disposed inside the two housings respectively, two solenoid valves being disposed on the two water pumps respectively, two water pipes being connected to the water pumps, the bottom hole being opened at the bottom of the shell, and a mixing component being disposed inside the shell.

[0006] Preferably, the cooling component further includes a heat insulation ring, which is fixedly connected to the connecting post, and the outer shell is fixedly connected to the heat insulation ring.

[0007] Preferably, the heat insulation ring is made of heat insulation material and is located between the connecting post and the outer shell.

[0008] Preferably, the mixing component includes rings and through holes, with multiple rings fixedly connected to the inside of the outer shell, and multiple through holes respectively opened on multiple rings.

[0009] Preferably, the plurality of rings are equally spaced inside the outer casing, and the plurality of through holes are located at different positions on the plurality of rings.

[0010] Preferably, a plurality of heat-conducting plates are fixedly connected to the base, and a bottom hole is provided between every two heat-conducting plates.

[0011] Compared with the prior art, the significant advantages of this utility model are:

[0012] Firstly, in this utility model, the base is connected by a connecting column, and then the base is connected to the pile head for pile driving. After pile driving, the base will have a high temperature and internal stress remaining. At this time, heat dissipation and stress elimination are required. Therefore, the heat-conducting plate on the base can increase the heat dissipation area and improve the heat dissipation efficiency. The two water pipes are used to connect hot and cold water respectively, and water pumps can be used to pump water into the outer shell. The amount of hot and cold water entering the outer shell is precisely controlled by a solenoid valve, thereby controlling the ratio of hot and cold water. By injecting the mixed water into the outer shell and then pouring it onto the base and heat-conducting plate through the bottom hole, heat can be dissipated from the base and heat-conducting plate. During the heat dissipation process, in order to eliminate internal stress, the temperature of the water poured onto the base needs to gradually decrease from hot to cold. Therefore, by controlling the ratio of hot and cold water by a solenoid valve, the temperature of the water poured onto the base can gradually change, thereby achieving the effect of eliminating internal stress.

[0013] Secondly, in this invention, when hot and cold water enter the outer casing, they are on a ring. The hot and cold water need to converge and then flow down through the through-hole on the ring to the next ring. The hot and cold water need to repeat this process until they finally reach the bottom of the outer casing and flow out from the bottom hole. During this process, since there are multiple rings and the position of the through-hole on each ring is different, the hot and cold water will be fully mixed on multiple rings to make the temperature of the water discharged from the bottom hole uniform.

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] This utility model provides an improved impact-resistant pile head base for pile drivers. The technical solution of this utility model is as follows:

[0023] like Figures 1-4 As shown, the impact-resistant pile head base for a piling machine includes a connecting column 1, a base 2 fixedly connected to the connecting column 1, and a cooling component 3 installed on the connecting column 1. The cooling component 3 includes a housing 31, a chassis 32, a water pump 33, a solenoid valve 34, a water pipe 35, and a bottom hole 36. The housing 31 is installed on the connecting column 1, and two chassis 32 are fixedly connected to the housing 31. Two water pumps 33 are respectively installed inside the two chassis 32, and two solenoid valves 34 are respectively installed on the two water pumps 33. The solenoid valves 34 can control the flow rate of water discharged from the water pumps 33 into the housing 31. Hot water and cold water are respectively drawn into the housing 31 through the two water pumps 33, and the flow rate is controlled by the solenoid valves 34, thereby realizing the adjustment of the hot and cold water ratio and controlling the final water temperature in the housing 31. Two water pipes 35 are connected to the water pumps 33, and the bottom hole 36 is opened at the bottom of the housing 31. A mixing component 4 is installed inside the housing 31.

[0024] In this embodiment, the cooling component 3 also includes a heat insulation ring 37, which is fixedly connected to the connecting column 1. The outer shell 31 is fixedly connected to the heat insulation ring 37. The function of the heat insulation ring 37 is to keep the water inside the outer shell 31 warm, so as to prevent the water from being cooled down inside the outer shell 31, thereby improving the accuracy of the water temperature throughout the process, so as to avoid problems with the elimination of internal stress of the base 2 caused by unstable water temperature.

[0025] In this embodiment, the heat insulation ring 37 is made of heat insulation material and is located between the connecting post 1 and the outer shell 31.

[0026] In this embodiment, the mixing component 4 includes rings 41 and through holes 42. Multiple rings 41 are fixedly connected to the inside of the outer shell 31, and multiple through holes 42 are respectively opened on multiple rings 41. Multiple rings 41 evenly divide the space inside the outer shell 31 into multiple layers. After the cold water and hot water discharged by the water pump 33 enter the outer shell 31, they need to be mixed between the multiple layers of rings 41 and finally discharged from the bottom hole 36. In this process, the cold and hot water can be fully mixed.

[0027] In this embodiment, multiple rings 41 are evenly spaced inside the outer casing 31, and multiple through holes 42 are located at different positions on the multiple rings 41. Since there are multiple rings 41 and the positions of the through holes 42 on each ring 41 are not consistent, hot and cold water will be fully mixed on the multiple rings 41 so that the temperature of the water discharged from the bottom hole 36 is uniform.

[0028] In this embodiment, a plurality of heat-conducting plates 21 are fixedly connected to the base 2, and a bottom hole 36 is provided between every two heat-conducting plates 21. The heat-conducting plates 21 can increase the heat dissipation area of ​​the base 2, and the water dripping from the bottom hole 36 can be evenly sprayed between every two heat-conducting plates 21, thereby achieving the effect of evenly guiding the water.

[0029] The specific working method is as follows: the base 2 is connected to the connecting column 1, and then the base 2 is connected to the pile head and pile driving is carried out. After pile driving, the base 2 will have a high temperature and internal stress. At this time, heat dissipation and internal stress elimination are required. Therefore, the heat-conducting plate 21 on the base 2 can increase the heat dissipation area and improve the heat dissipation efficiency. The two water pipes 35 are used to connect cold and hot water respectively, and water pump 33 can be used to pump water to allow cold and hot water to enter the outer shell 31. The amount of cold and hot water entering the outer shell 31 is precisely controlled by the solenoid valve 34, thereby controlling the ratio of cold and hot water. By injecting the mixed water into the outer shell 31 and then spraying it onto the base 2 and the heat-conducting plate 21 through the bottom hole 36, heat dissipation can be achieved for the base 2 and the heat-conducting plate 21. During the heat dissipation process, in order to eliminate internal stress, the temperature of the water sprayed on the base 2 needs to gradually change from hot to cold. Therefore, by controlling the ratio of cold and hot water by the solenoid valve 34, the temperature of the water sprayed on the base 2 can be gradually changed, thereby achieving the effect of eliminating internal stress.

[0030] When hot and cold water enter the outer casing 31, they are on the rings 41. The hot and cold water need to mix and then flow down through the through holes 42 on the rings 41 to the next ring 41. The hot and cold water need to repeat this process until they finally reach the bottom of the outer casing 31 and flow out from the bottom hole 36. During this process, since there are multiple rings 41 and the positions of the through holes 42 on each ring 41 are not consistent, the hot and cold water will be fully mixed on multiple rings 41 to make the temperature of the water discharged from the bottom hole 36 uniform.

Matters not covered in this utility model are common knowledge to those skilled in the art.
