[0032] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments, but the scope of protection claimed in the utility model is not limited to the following specific embodiments.

[0033] refer to Figure 1-2 ,

[0034] A high temperature resistant clamping device with a rear cylinder includes a forklift connecting seat 11, a rotating cylinder 12, a rotating frame 13 and two clamping arms 14. The rotating cylinder 12 is fixedly mounted on the forklift connecting seat 11, the rotating frame 13 is mounted on the rotating cylinder 12, and the clamping arm 14 is rotatably mounted on the rotating frame 13. The two clamping arms 14 are symmetrically arranged. The clamping arm 14 includes a supporting section 21, a heat dissipation section 31 and a clamping section 41. The supporting section 21 is rotatably connected to the rotating frame 13. The two ends of the heat dissipation section 31 are respectively fixed to the supporting section 21 and the clamping section 41. A telescopic cylinder 22 is arranged between the rotating frame 13 and the supporting section 21. The two ends of the telescopic cylinder 22 are respectively rotatably connected to the rotating frame 13 and the supporting section 21. The clamping section 41 is rotatably connected with a heat insulating clamping plate 42. The heat insulating clamping plate 42 is in contact with a high temperature object to achieve a heat insulating effect.

[0035] The heat dissipation section 31 is provided with a heat dissipation structure, which includes a plurality of heat dissipation plates 32, and the heat dissipation plates 32 are fixedly connected to the heat dissipation section 31. The heat dissipation section 31 is provided with a ventilation slot 33, and the heat dissipation plates 32 are located in the ventilation slot 33, and the plurality of heat dissipation plates 32 are parallel to each other. The heat dissipation section 31 is provided with an air inlet 34 connected to the ventilation slot 33, and the heat dissipation section 31 is installed with a fan 35 located at the air inlet 34. The air inlet 34 is located at one end of the ventilation slot 33 close to the support section 21. The heat dissipation section 31 is fixedly connected with a partition plate 36 located in the ventilation slot 33, one end of the partition plate 36 is fixedly connected to the heat dissipation plate 32 located in the middle of the ventilation slot 33, and the end of the partition plate 36 away from the heat dissipation plate 32 is located in the middle of the air outlet end of the fan 35. The opening of the ventilation slot 33 faces the middle position of the two clamping arms 14. The air inlet 34 is located on the side of the heat dissipation section 31 away from the opening of the ventilation slot 33. The heat dissipation section 31 is inclined toward the middle position of the two clamping arms 14 on the supporting section 21 , and the clamping section 41 is inclined toward the middle position of the two clamping arms 14 on the heat dissipation section 31 .

[0036] This embodiment has the following advantages:

[0037] The extension and contraction of the telescopic cylinder 22 can drive the clamping arms 14 to rotate on the rotating frame 13, so that the two clamping arms 14 can clamp the object at the clamping section 41, thereby realizing the function of clamping the object. The rotating cylinder 12 drives the rotating frame 13 and the clamping arms 14 to rotate, thereby realizing the function of driving the object to rotate.

[0038] When clamping a high-temperature object, since the distance between the clamping section 41 and the high-temperature object is relatively close, and the support section 21 is located at the end of the clamping arm 14 away from the clamping section 41, the heat is also continuously diffused into the air during the process of being transferred to the support section 21 through the heat dissipation section 31, thereby reducing the heat transferred to the support section 21, making the clamping section 41 have a higher temperature and the support section 21 have a lower temperature. Therefore, the support section 21 with a lower temperature can be connected to the telescopic oil cylinder 22, which can effectively reduce the temperature of the telescopic oil cylinder 22, increase the service life of the telescopic oil cylinder 22, prevent the hydraulic oil from being overheated after being heated, and improve the stability of the hydraulic system, thereby achieving the advantage of good heat resistance.

[0039] By setting the heat dissipation plate 32, the contact area between the heat dissipation section 31 and the heat dissipation plate 32 as a whole and the air is increased, which is beneficial to diffuse the heat of the heat dissipation section 31 into the air, thereby improving the heat dissipation effect of the heat dissipation section 31, further preventing the hydraulic cylinder connected to the support section 21 from overheating, and achieving the advantage of better heat resistance.

[0040] By providing the ventilation slots 33 , the air can flow on the surface of the heat sink 32 during the process of air flowing through the ventilation slots 33 , thereby improving the heat dissipation effect of the heat sink 32 .

[0041] The fan 35 drives the air at the air inlet 34 to enter the ventilation slot 33 , thereby achieving the function of driving the air flow in the ventilation slot 33 .

[0042] Since the temperature at the supporting section 21 is lower and the temperature at the clamping section 41 is higher, the air inlet 34 and the fan 35 are arranged at a position close to the supporting section 21, so that the temperature of the air entering the ventilation groove 33 through the air inlet 34 is lower, thereby improving the heat dissipation effect of the air on the heat sink 32, and can reduce the temperature of the fan 35, thereby improving the service life and stability of the fan 35.

[0043] After the fan 35 blows air into the ventilation slot 33, a portion of the air is guided to the end of the ventilation slot 33 close to the clamping section 41 through the heat insulation plate, ensuring that the heat sink 32 closer to the clamping section 41 can also obtain a better heat dissipation effect, thereby improving the overall heat dissipation effect of the heat sink 31. It can also prevent the fan 35 from blowing out from the end of the ventilation slot 33 close to the support section 21 and then entering the ventilation slot 33 from the end of the ventilation slot 33 close to the clamping section 41, thereby preventing the formation of vortices in the ventilation slot 33, thereby ensuring the heat dissipation effect of the air on the heat sink 32.

[0044] The air is discharged from the ventilation slot 33 through the opening and blown toward the high-temperature object of the two clamp arms 14 , which can prevent the high-temperature air around the high-temperature object from flowing toward the clamp arms 14 , thereby preventing the clamp arms 14 from being overheated.

[0045] The air inlet 34 and the openings of the ventilation slot 33 are respectively located on both sides of the heat dissipation section 31 to prevent the hot air discharged from the ventilation slot 33 from being sucked into the air inlet 34 , thereby ensuring the heat dissipation effect of the air on the heat dissipation plate 32 .

[0046] The heat dissipation section 31 and the clamping section 41 are inclined toward the clamped high-temperature object, thereby increasing the distance between the support section 21 and the high-temperature object, further reducing the heat transferred to the support section 21, and improving the heat insulation effect.

[0047] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
