Description

Technical Field

[0001] The utility model relates to the field of cranes, and particularly relates to an orbital spring rail clamp system. Background Art

[0002] Most of the brakes for preventing wind of existing orbital lifting and running machinery (referred to as "main machine") adopt clamp type. Its working principle is that the rail clamp connected to the main machine is transmitted by the spring force or gravity through the connecting rod mechanism, so that the clamp jaws clamp the rail, in order to prevent the main machine from being blown away by strong wind. When the main machine moves, the clamp jaws are released by the hydraulic system. The clamp jaw mechanism of the existing rail clamp is fixedly connected to the frame, the frame is connected to the main machine through a connecting shaft and a connecting frame, the supporting wheels fixed on the frame are in contact with the rail, and the guiding wheels are suspended and fixed on the connecting shaft. When the height difference of the rail is large, the jaw is raised and cannot clamp the rail, or the guiding wheel squeezes the rail downward and causes damage. In addition, due to the unevenness of the rail after being used for a period of time and the shaking of the main machine during operation, the non-working wear of the guiding wheel and the jaw is serious, the service life is reduced, the side gap between the jaw of the rail clamp and the rail increases, the working stroke of the clamp jaw increases, and the size of the connecting rod mechanism increases.

[0080] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0081] The utility model discloses a track type spring rail clamp system, such as Figures 1-7 As shown, it includes a hydraulic system 1, a main clamp mechanism 2, and a body structure 3. The hydraulic system 1 includes a hydraulic cylinder 130. The main clamp mechanism 2 includes a main spring, a clamp connecting rod, a jaw iron 231, and a guide wheel group. The main spring includes a right-handed first spring 211 and a left-handed second spring 212. The outer diameter of the first spring 211 is larger than the outer diameter of the second spring 212. The first spring 211 is coaxially embedded outside the second spring 212. The clamp connecting rod includes a connecting rod 221, a clamp 228, a striker 225 and a limit switch 229. The connecting rod 221 is a two-force rod. The hydraulic cylinder 130, the connecting rod 221, the first spring 211, and the first spring 211 are all arranged in the clamp 228. The two sides of the top of the clamp 228 are respectively connected to the two sides of the hydraulic cylinder 130 from top to bottom, and are respectively connected to the two sides of the top of the connecting rod 221. The bottom end of the connecting rod 221 is connected to the top of the first spring 211 and the second spring 212. The jaw iron 231 is set on the clamp 228, and the jaw iron 231 is abutted against the side of the track 450. The top of the guide wheel group is connected to the limit switch 229, and the bottom of the guide wheel group is slidably connected to the track 450. The body structure 3 is supported between the top and bottom of the guide wheel group. The inner end of the impact plate 225 is connected to the rotating shaft of the connecting rod 221 and is coaxial with the rotating shaft of the connecting rod 221. The outer end of the impact plate 225 is arranged at the lower side periphery relative to the limit switch 229.

[0082] Specifically, the connecting rod 221 consists of two rods, and the bottom ends are rotatably connected by a rotating shaft. The first spring 211 and the second spring 212 are preloaded elastic elements. The guide wheel set is slidably connected to the track 450, and one side of its top supports the body structure 3, forming a floating structure without mechanical connection. The jaw iron 231 directly contacts the side of the track 450 to provide the frictional force required for braking.

[0083] This device is a mechatronic product with a normally closed design. It uses a nested design of two springs, the first spring 211 and the second spring 212, which are preloaded to provide a greater clamping force for the clamp 228 in the same size space. The main clamp mechanism 2 has a floating structure without mechanical connection to the clamp seat 310. During operation, the main clamp mechanism 2 effectively fits the surface of the track 450, and the guide wheels 242 and the jaws do not have abnormal wear, with a long service life, stable and reliable operation, effectively overcoming the phenomenon that the clamp 228 of the existing spring rail clamp cannot work effectively when the track 450 is uneven. The hydraulic system 1 can steplessly adjust the closing time of the clamp 228, and cooperate with the limit switch 229 to effectively keep the clamp 228 released through the electric control system. The track-type spring rail clamp system solves the problems of side wear of the guide wheels and non-working wear of the jaw irons of the original spring rail clamp during use due to the unevenness of the main machine track, effectively ensuring that the guide wheels 242 closely adhere to the top surface of the track 450, and the clamp jaws have a reasonable and effective working stroke with the side of the track 450. The main clamp mechanism is tensioned by the preloaded spring force. When the hydraulic system 1 is powered on, oil is supplied to the hydraulic cylinder 130 to release the main clamp mechanism. When powered off, the hydraulic cylinder 130 is depressurized, and the main clamp mechanism works to clamp the track main machine for braking. The normally closed design system works reliably and safely. When the hydraulic system fails or there is no mains power, the main clamp mechanism can be released by operating the manual pump 125 to supply oil to the hydraulic cylinder 130, and the emergency operation is convenient for system maintenance and repair.

The oil inlet of the valve block is communicated with the fuel tank 141, and the oil outlet of the valve block is communicated with the hydraulic cylinder 130 through two hydraulic hoses 146. The two hydraulic hoses 146 are respectively communicated to the cylinder barrels 131 on both sides of the piston. The hydraulic hoses 146 convey hydraulic oil.

[0107] The hydraulic cylinder 130 includes a cylinder barrel 131, a piston, a piston rod 132, a guide sleeve, and an earring 133.

[0108] The fuel tank pipeline accessories include a fuel tank 141, a cover plate 142, an oil suction filter, a liquid level gauge 144, an air filter 145, hydraulic hoses 146, and a pressure gauge 143. The fuel tank 141 is a storage and heat dissipation container for hydraulic oil. The oil suction filter is arranged in the hydraulic pipeline. When the gear pump or the manual pump 125 pumps hydraulic oil, the oil suction filter has the function of filtering hydraulic oil, reducing the failure rate of the hydraulic system 1 and enabling the whole system to work more smoothly. The liquid level gauge 144 is arranged on the side wall of the fuel tank 141 and is communicated with the inside of the fuel tank 141. The liquid level gauge 144 has the function of indicating the liquid level. The air filter 145 is arranged on the cover plate 142. Installation holes are drilled on the cover plate 142 into the fuel tank 141, and the outside air can enter the fuel tank 141 through the air filter 145. The air filter 145 filters the air entering the fuel tank 141. The pressure gauge 143 is also arranged on the valve block and is connected to the hydraulic oil pipeline, serving as a pressure indicating instrument for the hydraulic system 1.
