Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 2 to 5, the lifting device with the snow-proof cover steel spring for the bogie of the high-speed motor train unit comprises: the lifting ring comprises a lifting ring 1, a guide rod 2, a connecting ring 3, three connecting rods 4, a handle 5, a support frame 6, three groups of support rods 7 and three support claws 8; the lifting ring 1 is fixedly connected to the top end of the guide rod 2, the upper part of the guide rod 2 is a polished rod, and the lower part of the guide rod 2 is provided with external threads; the lifting ring 1 is connected with a lifting hook 10 of the intelligent lifting equipment, and the whole lifting device and the spiral steel spring 9 of the thermal shrinkage snow-proof rubber sleeve can be borne by the lifting ring 1.
The connecting ring 3 is sleeved at the upper part of the guide rod 2, the upper parts of the three connecting rods 4 are respectively connected with the connecting ring 3 by shafts, and the three connecting rods 4 are distributed at equal intervals of 120 degrees by taking the connecting ring 3 as the center; one end of the handle 5 is fixedly connected with the connecting ring 3; the connecting ring 3 moves upwards or downwards along the guide rod 2 by lifting or pulling the handle 5 downwards, so that the three connecting rods 4 and the supporting claw 8 can contract or expand around the center of the connecting ring 3, and the supporting claw 8 can be conveniently extended into or pulled out of the spiral steel spring 9.
The support frame 6 is in threaded connection with the lower portion of the guide rod 2, one ends of three groups of support rods 7 are respectively in shaft connection with the support frame 6, the other ends of the three groups of support rods 7 are respectively in corresponding shaft connection with the middle portions of the three connecting rods 4, and the three groups of support rods 7 are uniformly distributed at intervals of 120 degrees on the circumference by taking the support frame 6 as the center. Support frame 6 is in the same place through threaded connection with guide bar 2, the lifting effect power of transmitting by rings 1 is used on guide bar 2, will play lifting force and transmit support frame 6, support frame 6 upward movement, will play lifting force transmission again for three connecting rod 4 through support frame 6, make three connecting rod 4 be in open trend round connecting ring 3, but because of the structure restriction of 9 inner circles of coil spring, lead to at the handling in-process, the lateral surface of three connecting rod 4 pastes the inner circle surface of leaning on coil spring 9 all the time, thereby realize hoisting device's self-locking function, prevent that handling in-process coil spring 9 accident from droing.
The three support claws 8 are fixedly connected to the lower parts of the three connecting rods 4 in a one-to-one correspondence manner, and the support claws 8 and the connecting rods 4 are extended or contracted together. The bearing surfaces of the three supporting claws 8 are contact surfaces acting on the steel ring of the spiral steel spring 9, the height difference exists among the bearing surfaces of the three supporting claws 8 according to the pitch size of the spiral steel spring 9, the shapes of the bearing surfaces of the three supporting claws 8 and the spiral line shape of the steel ring of the spiral steel spring 9 are kept consistent, and the inclination of the spiral steel spring 9 in the hoisting process is avoided. The outer surfaces of the three supporting claws 8 are provided with a layer of protective sleeve in a heat-shrinkable mode and are used for preventing the lifting device from damaging paint on the surface of the spiral steel spring.
As shown in figure 5, when the lifting device with the snow-proof cover steel spring for the high-speed motor train unit bogie is used, the lifting device is firstly hung on a lifting hook 10 of an intelligent lifting equipment operating handle through a lifting ring 1, then the operating handle of the intelligent lifting equipment is held by a hand, and the lifting hook 10 and the lifting device can move in any direction along with an operator through a gravity sensor arranged on the intelligent lifting equipment. Moving the lifting device above the spiral steel spring 9, then holding a handle 5 of the lifting device by an operator, slightly lifting the handle 5, enabling three support claws 8 of the lifting device to contract until the support claws 8 can be deeply inserted into the inner ring of the spiral steel spring 9, then slightly loosening the handle 5, and automatically expanding the support claws 8 through self weight until the support claws are attached to the inner ring of the spiral steel spring 9; then, an operator manually controls an operating handle of the intelligent lifting equipment, and the spiral steel spring 9 can be lightly lifted. Because the lifting device provided by the invention realizes lifting by inserting the supporting claw 8 into the inner ring of the spiral steel spring 9 to hook the spiral steel spring 9, the lifting device can realize convenient lifting of the spiral steel spring 9 before and after thermal shrinkage.
