When a bogie frame 1 and a wheel set axle box spring assembly 2 are dropped, an operator is needed to be arranged at each of four corners of the frame 1, when an overhead traveling crane suspension frame 1 slowly drops onto two wheel sets, four operators see whether a pressure plate boss 2-1-1 of the four axle box spring assemblies 2 accurately and centrally drops into a cap barrel center hole 1-1-1 of the frame, if the frame 1 does not drop into the hole after dropping, a jack is needed to be used and a crowbar is matched to insert the pressure plate boss 2-1-1 into the cap barrel center hole 1-1-1, the prying process needs the operator to have certain operation experience, sometimes the overhead traveling crane suspension frame is needed to be reused to drop again, and the operation is time-consuming and labor-consuming.
Disclosure of Invention
The invention provides an adjusting device for the drop of a bogie frame and a wheel set axle box spring, which aims to solve the technical problems of time and labor waste in operation, high labor intensity and low working efficiency in the existing drop mode of the frame and the wheel set axle box spring.
The technical scheme adopted by the invention for solving the technical problem is as follows:
the adjusting device for the forming is composed of a bogie frame and wheel set axle box springs and comprises an adjusting rod, a guide washer and an adjusting bolt; the guide gasket is of a circular truncated cone structure, a gasket boss is coaxially arranged at the bottom of the guide gasket, the outer diameter of the gasket boss is smaller than the diameter of the bottom surface of the guide gasket and equal to the aperture of a central hole of an upper pressure plate consisting of wheel set axle box springs, and a gasket central through hole penetrating along the axial direction is arranged in the center of the guide gasket; the diameter of the upper end part of the adjusting bolt is larger than the aperture of the central through hole of the gasket and smaller than the diameter of the upper end surface of the guide gasket, the upper part of the adjusting bolt is inserted into the central through hole of the gasket of the guide gasket and is in threaded connection with the central hole of the positioning seat formed by the axle box spring of the wheel pair, the center of the adjusting bolt is provided with a central slotted hole along the axial direction, and the external thread at the front end of the adjusting rod is in threaded connection with the internal thread of the.
The invention has the beneficial effects that: when the framework and the wheel pair fall, the position of the four axle box springs can be controlled and adjusted by utilizing the conical guiding function of the guide gasket and the swinging adjusting function of the central slotted hole of the adjusting bolt, so that the smooth falling of the wheel pair and the framework is ensured. The device simple structure, convenient operation, labour saving and time saving has improved work efficiency, and the device is applicable to the bogie of a plurality of motorcycle types of structure similarity and falls into.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 4 to 6, the adjusting device for the bogie frame and the wheel-set pedestal spring assembly of the present invention comprises: an adjusting rod 3, a guide washer 4 and an adjusting bolt 5; the guide gasket 4 is made of vulcanized rubber, so that the rigidity can be ensured, and certain flexibility is realized.
The guide gasket 4 is in a circular truncated cone structure, a gasket boss 4-1 is coaxially arranged at the bottom of the guide gasket 4, the outer diameter of the gasket boss 4-1 is smaller than the diameter of the bottom surface of the guide gasket 4 and is slightly smaller than the aperture of an upper pressure plate center hole 2-1-2 of the wheel set axle box spring assembly 2, so that the gasket boss 4-1 can be just inserted into the upper pressure plate center hole 2-1-2 without a gap between the gasket boss and the upper pressure plate center hole, and a gasket center through hole 4-2 which penetrates through the center of the guide gasket 4 along the axial direction.
The diameter of the upper end part of the adjusting bolt 5 is larger than the aperture of the central through hole 4-2 of the gasket and smaller than the diameter of the upper end face of the guide gasket 4, the upper part of the adjusting bolt 5 is inserted into the central through hole 4-2 of the gasket of the guide gasket 4 and is in threaded connection with the central hole 2-4-1 of the positioning seat of the wheel set axle box spring assembly 2, the center of the adjusting bolt 5 is provided with a central slotted hole 5-1 along the axial direction, and the external thread at the front end of the adjusting rod 3 is in threaded connection with the internal thread of the central slotted hole 5-.
Referring to fig. 1 to 6, when the bogie frame and the wheel set axle box spring assembly of the invention are used as an adjusting device, four sets of adjusting devices of the invention are needed, the lower part of an adjusting bolt 5 of each set of adjusting device is coaxially screwed into a positioning seat central hole 2-4-1 until a gasket boss 4-1 of a guide gasket 4 is coaxially inserted into an upper pressure plate central hole 2-1-2, so that the bottom surface of an outer ring of the guide gasket 4 is clamped on the upper end surface of the pressure plate boss 2-1-1; then, a crane is used for hoisting the framework 1 to the position above the four wheel pair axle box spring assemblies 2, the four spring cap cylinders 1-2 of the framework 1 slowly fall to the four wheel pair axle box spring assemblies 2, and under the conical guiding action of a guide gasket 4 of each set of adjusting device, the four spring cap cylinders 1-2 can be quickly sleeved on the four wheel pair axle box spring assemblies 2; when the pressure plate boss 2-1-1 is not accurately inserted into the cap cylinder central hole 1-1-1, the front end of the adjusting rod 3 is sequentially screwed into the cap cylinder central hole 1-1-1 and the central slotted hole 5-1 of the adjusting bolt 5, so that the pressure plate boss 2-1-1 can be quickly and accurately inserted into the cap cylinder central hole 1-1-1, and the assembly 2 of the framework 1 and the wheel set axle box spring is completed.
