Description
Technical Field
The invention belongs to the field of auxiliary installation devices of elastic traction center components for a bogie, and particularly relates to an auxiliary installation device of an elastic traction center component for a bogie.
Background
The traction center component is a key component for realizing connection of a rail train bogie and a train body steel structure and transmitting traction force and braking force, and as shown in fig. 4 to 8, the traction center component of a certain type comprises an integrated spring seat center cylinder 1, four laminated rubber springs 2 and four spring positioning end plates 3, two wing-shaped double-sided spring seats 1-1 parallel to the axial direction of the integrated spring seat center cylinder 1 are symmetrically arranged on two sides of the outer diameter of the integrated spring seat center cylinder 1, and a center cylinder spring mandrel positioning hole 1-1-1 is formed in the center of the double-sided spring seat 1-1. The width value of the spring positioning end plate 3 is d1, two lug plates 3-2 integrally formed with the spring positioning end plate are symmetrically arranged on two sides of the lug plate 3-3, the lug plate 3-3 protrudes outwards from the end face of the lug plate 3-2 to form a boss with the length of F1 and the height of H1, so that the side view of the spring positioning end plate 3 is similar to the Chinese character shape, the rear end face of the lug plate 3-3 is inwards recessed to form an end plate spring positioning groove 3-1 on the basis of the rear end faces of the two lug plates 3-2, and the center of the end plate spring positioning groove 3-1 is provided with an end plate spring mandrel jack 3-1-1. Two ends of the spring positioning end plate 3 are respectively provided with a group of end plate positioning screw holes 3-2-1. The front and rear end surfaces of the laminated rubber spring 2 are respectively provided with a spring mandrel 2-1, one spring mandrel 2-1 is coaxially inserted into an end plate spring mandrel insertion hole 3-1-1 on the corresponding end plate spring positioning groove 3-1, and the other spring mandrel 2-1 is inserted into a mandrel spring mandrel positioning hole 1-1-1 of the spring seat central cylinder 1. The front end face and the rear end face of the double-sided spring seat 1-1 of each spring seat central cylinder 1 are in mirror symmetry and are respectively in contact connection with one laminated rubber spring 2 in one-to-one correspondence, and the two laminated rubber springs 2 share the same central cylinder spring mandrel positioning hole 1-1-1. As shown in fig. 7 and 8, the initial distance value of the outer end convex surfaces of the two spring positioning end plates 3 of the two laminated rubber springs 2 positioned on both sides of the same double-sided spring seat 1-1 in the natural extension state is D1.
As shown in fig. 1 to 3, a certain traction center component N is positioned and installed in a rectangular inner crotch M formed by framework beams, two opposite inner side walls of the inner crotch M formed by the framework beams are respectively and radially symmetrically provided with a spring positioning end plate mounting seat T, and each spring positioning end plate mounting seat T is provided with two end plate outward protruding surface positioning grooves E corresponding to the laminated rubber springs 2 and the positions of the spring positioning end plates 3 thereof in a matching manner. The outer protruding surface of the end plate of each spring positioning end plate 3 is propped in a corresponding outer protruding surface positioning groove E of the end plate under the action of the elastic force of the laminated rubber spring 2, and the front end surface and the rear end surface of each double-sided spring seat 1-1 are clamped by the corresponding two laminated rubber springs 2 under the action of the elastic force, so that the integrated spring seat center cylinder 1 is elastically suspended and positioned in an inner crotch M formed by frame beams under the action of the common clamping force of the four laminated rubber springs 2, and the integrated spring seat center cylinder is used for installing a traction center pin and transmitting the traction force of a bogie to a vehicle body.
However, under the natural length of the laminated rubber spring 2 without stress, the distance value between the outer end surfaces of the two spring positioning end plates 3 which are in mirror symmetry with the front and rear of the double-sided spring seat 1-1 is larger than the width value of the inner crotch M formed by the framework beams, so that when the traction center assembly N with the laminated rubber spring is installed in the inner crotch M formed by the existing framework beams, the traction center assembly N needs to be integrally compressed by adopting a vertical press machine, the value of D1 is smaller than the inherent width value of the inner crotch M formed by the framework beams, and then two ends of the 4 special double-thread pull rods are respectively connected with the lug threaded holes 3-2 of the spring positioning end plates 3 through bolts, so that the integral compressed state of the traction center assembly N is ensured to be unchanged. Thereafter, the compressed traction center assembly N is then suspended in the crotch M of frame rails and in the aligned mounting position, ready to re-release the compression set of the laminated rubber springs 2. However, because the spring positioning end plates 3 at the front and rear ends of the double-sided spring seat 1-1 are continuously opened by the elastic restoring force of the laminated rubber spring 2, the lug threaded holes 3-2 have larger reaction force on 4 special double-ended threaded pull rods of the compression traction center assembly N, so that the two ends of each special double-ended threaded pull rod are in excessive static friction force with the threaded connection of the corresponding lug threaded holes 3-2, and the threaded connection is difficult to disassemble.
In addition, when the laminated rubber spring 2 is compressed in two directions by the F-shaped industrial clamp, a great force needs to be applied, and after the traction center assembly N is hung in the inner crotch M formed by the frame beams, the clamping contact surface between the outer side end surface of the spring positioning end plate 3 and the F-shaped industrial clamp is very narrow, the F-shaped industrial clamp is easy to suffer from uneven stress when the laminated rubber spring 2 is compressed, and the F-shaped industrial clamp is often burst out. On the other hand, the situation that the spring positioning end plate 3 is mounted in an improper position can happen occasionally after the special double-thread pull rod is dismounted, and the position of the spring positioning end plate 3 needs to be adjusted by a crowbar to enable the spring positioning end plate 3 to be mounted in an proper position, but the crowbar is not suitable for crowbar operation because the inner crotch formed by the framework cross beams is too narrow, the condition that the crowbar slips off and bumps on bogie parts is easy to happen, so that the existing assembly mode is low in efficiency, personal safety of operators can be threatened, and meanwhile, the bogie is easy to damage, so that the assembly quality and the assembly efficiency of the integrated spring seat central cylinder 1 are affected.
Disclosure of Invention
When the existing certain traction center assembly N is required to be installed in an inner crotch formed by framework beams in a compressed state, the traction center assembly N is required to be precompressed by a vertical press, the compression state of the traction center assembly N is kept fixed by a plurality of special double-thread pull rods, the traction center assembly N is then hung at an inner crotch installation position formed by the framework beams, an operator further compresses the traction center assembly N by using F-shaped industrial clamps so as to smoothly detach the special double-thread pull rods from spring positioning end plates corresponding to the two ends of the special double-thread pull rods, and then the lever force of a crowbar is utilized to finish the normal position adjustment under the condition of the installation misalignment of the traction center assembly N. Because the F-shaped industrial clamp and the crowbar are required to exert great force during operation, and the narrow working space in the inner crotch formed by the framework beams leads to the problems that the F-shaped industrial clamp has small available clamping surface and is easy to bear uneven force, the F-shaped industrial clamp is frequently broken out, the traction center assembly N is not installed in place, the crowbar slips off and the like, the installation process of the traction center assembly is time-consuming and labor-consuming and has low efficiency, the personal safety of operators can be threatened, and meanwhile, the condition of damaging the bogie is easy to cause, the invention provides the auxiliary installation device for the elastic traction center assembly of the bogie, and the auxiliary installation device for the elastic traction center assembly of the bogie is used for solving the technical problems.
