Abstract
The invention discloses a shell weld stud type retarder, radically solves the problem that the conventional retarder shell is inconvenient to mount, and provides a novel retarder which is convenient to mount and construct and has long service life. The shell weld stud type retarder comprises a shell and a cylinder assembly inserted into the shell, and has the technical key points that: a pair of grooves is formed on the outer side of the shell; a pair of single end studs is welded in the grooves; and a small hole for buffer stop is formed at the tail of the cylinder assembly, extends from the bottom of the shell and is inserted into a buffer stop pin to realize buffer stop. Processes such as drilling, tapping, screwing double end studs into the shell and the like are replaced by a welding process, so that machining processes are reduced, production cost is reduced, manufacturing quality is improved and production efficiency is improved.
Description
Technical field
The present invention relates to railway vehicle deceleration top, particularly a kind of housing welding screw formula of being convenient to install is slowed down and is pushed up.
Background technology
Slowing down to push up is widely used in yard, and skating vehicle is slowed down.Slow down to push up and be made up of hydraulic cylinder assembly and housing assembly two large divisions, hydraulic cylinder assembly is inserted in the housing of housing assembly, utilizes to end writing off to connect hydraulic cylinder assembly and housing assembly, and housing is fixed on the rail side.All be shaped on tapped bore on the housing on existing deceleration top, installation form has two kinds, a kind ofly be: the end with double end stud before dispatching from the factory screws in the tapped bore of housing, during on-site installation the mounting hole of double-screw bolt from circuit rail one side is passed, and housing is fixed with spring washer and nut at opposite side; Another kind is: in a side of circuit rail the tapped bore of housing is directly aimed at the mounting hole of rail during on-site installation, housing is fixed with the bolt and spring washer circle at opposite side.Screw rod penetrated in the mounting hole of rail and installs than being easier to when the former installed, but dispatching from the factory before as negligence of operation, double end stud is not tightened with housing, is difficult in appearance discovering, generation is in use become flexible after the installation, causes the damage of double-screw bolt and housing.The mounting hole that the tapped bore of housing is aimed on the rail could need be screwed in bolt when the latter installs, installation difficulty is higher than the former.
Summary of the invention
The objective of the invention is fundamentally to solve existing deceleration top housing inconvenient problem is installed, and then provide a kind of installation convenient for more reasonably housing welding screw formula deceleration top of a kind of housing structure design is provided, the novel deceleration top of long service life.
Technical scheme of the present invention is: this housing welding screw formula is slowed down and is pushed up, and comprises housing and is inserted into the interior hydraulic cylinder assembly of described housing, and its technical essential is: described hull outside casts out a pair of groove, and welds a pair of double-screw bolt in described groove.
The afterbody of described hydraulic cylinder assembly is provided with end to dash use aperture, described end dashing stretch out from described housing bottom with aperture, and insert to end and write off realization and only dash.
Described double-screw bolt is the single head double-screw bolt.
Advantage of the present invention and positive technique effect: owing to utilize welding sequence to weld double-screw bolt in the groove that deceleration of the present invention top housing casts out outward, the installation on top had both been avoided dispatching from the factory preceding as negligence of operation so slow down, double-screw bolt is not tightened with housing and is caused and produce the situation of becoming flexible, cause double-screw bolt and housing to damage in the use after the installation, reached easy for installation again, reliable fastening purpose has prolonged service life of product.The present invention utilizes welding sequence to substitute boring, tapping and double-screw bolt and is screwed into operations such as housing, has reduced manufacturing procedure, has reduced productive costs, has improved build guality, enhances productivity.
Description of drawings
The invention will be further described in conjunction with the accompanying drawings:
Fig. 1 is a kind of structural representation sketch of the present invention;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the connection diagram of the present invention and track;
Sequence number explanation among the figure: 1 hydraulic cylinder assembly, 2 housings, 3 end abatement, 4 grooves, 5 double-screw bolts, 6 rail, 7 nuts, 8 spring washers, 9 mounting holes.
The specific embodiment
Couple the present invention is described in detail according to Fig. 1-3.This housing welding screw formula is slowed down and is pushed up, and is made up of housing and the hydraulic cylinder assembly that is inserted in the housing, and wherein: hull outside casts out a pair of groove 4, and welds a pair of single head double-screw bolt 5 in groove 4.
The afterbody of hydraulic cylinder assembly 1 is provided with end to dash use aperture, end dashing and stretch out from housing 2 bottoms with aperture, and end dash with aperture in insertion only write off 3 realizations and only dash.
The present invention is slowed down, and the top housing casts out a pair of groove 4 outward and distinguish welding screw 5 in groove, has promptly substituted boring, tapping and screw rod with welding sequence and has been screwed into operations such as housing.
During installation, in a side of circuit rail 6 is directly passed the double-screw bolt 5 of housing 2 mounting hole 9 on the rail 6, fastening with spring washer 8 and nut 7 at the opposite side of rail 6.
Claims (3)
1. a housing welding screw formula deceleration top comprises housing and is inserted into the interior hydraulic cylinder assembly of described housing, and it is characterized in that: described hull outside casts out a pair of groove, and welds a pair of double-screw bolt in described groove.
2. the housing welding screw formula according to claim 1 top of slowing down, it is characterized in that: the afterbody of described hydraulic cylinder assembly is provided with to end dashing use aperture, described end dashing stretch out from described housing bottom with aperture, and insert to end and write off realization and only dash.
