Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof, in particular to an explosion-proof lifting vehicle. Background Art

[0002] In the process of transporting materials in factories, it is often necessary to transport heavy objects from the ground to the platform. The objects to be transported are relatively heavy, and hydraulic cylinders are usually used to lift and lower heavy objects. Hydraulic cylinders are hydraulic actuators that convert hydraulic energy into mechanical energy and perform linear reciprocating motion (or swinging motion). They have a simple structure and reliable operation. When using them to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so they are widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device.

[0003] However, when the hydraulic cylinder is used to lift heavy objects, the following problems may occur:

[0004] 1. When the hydraulic cylinder is working, the hydraulic pressure inside the hydraulic cylinder will be too high when the lifted workpiece is heavy, causing the cylinder body to explode. It is also easy for the cylinder body to deform and burst. In addition, the high pressure during the support process of the hydraulic rod may cause the piston rod to tilt, affecting the use of the hydraulic equipment.

[0005] 2. When the hydraulic cylinder explodes, there are no external protective measures, and the explosion fragments are not mitigated by measures, causing them to fly around, causing damage to other devices. In serious cases, it will cause physical harm to the staff operating the accessories. At the same time, the explosion causes the hydraulic oil to splash directly, causing waste.

At the same time, the walking wheel 11 is a single-sided wheel, and the walking wheel 11 is driven to move by the existing motor, reduction box and gear box to make the device walk and move. The explosion-proof lifting component includes an explosion-proof component 2 and a lifting rod 3. The lifting rod 3 includes a hydraulic cylinder 31 and a hydraulic rod 32. The hydraulic rod 32 is located inside the explosion-proof tube 21 and is fixedly connected to the fixed plate 22. The explosion-proof ring 24 and the explosion-proof hoop 25 are wrapped around the outer wall of the hydraulic cylinder 31. The hydraulic cylinder 31 is pressurized or reduced to achieve the state of pushing out or retracting the hydraulic rod 32, thereby achieving the lifting effect. The explosion-proof ring 24 and the explosion-proof hoop 25 wrapped around the outer wall of the hydraulic cylinder 31, after the hydraulic cylinder 31 is subjected to huge pressure, the explosion-proof ring 24 and the explosion-proof hoop 25 are still wrapped around the outer wall of the hydraulic cylinder 31 to prevent it from exploding, so that the lifting rod 3 can withstand greater pressure and is safer to use.
