Description

A kind of resilient supporting unit that is used for the steel billet transport trolley

Technical field

The utility model belongs to the handling machinery field, is specifically related to the shock proof resilient supporting unit of a kind of energy, is used for the elastic support between steel billet transport trolley vehicle frame and the set of wheels.

Background technology

The steel billet transport trolley generally is used for the mistake in the parallel workshop of steel rolling mill and strides transportation, and horizontal mistake is striden on the ground-surface track and moved in the workshop.The steel billet transport trolley runs to the appointed place, steel billet is hung onto on the upper table surface of steel billet transport trolley by weight-lifting equipment, because when placing steel billet, the steel billet that weight is bigger can produce greater impact when falling on the transport trolley table top.Between the vehicle frame of metallurgical transport vehicle commonly used and the set of wheels is rigidly connected, the steel billet that frequently fall this moment will produce repeatedly bigger impact to vehicle frame, the load that vehicle frame bore is much larger than load carrying ability, just Vehicle Frame Design must be got very heavy, not only increase the manufacturing cost of steel billet transport trolley, and increased the energy consumption when transport trolley moves.

Summary of the invention

To the impact of steel billet transport trolley, the utility model proposes a kind of resilient supporting unit when falling, be used for the supporting between transport trolley vehicle frame and the set of wheels in order to slow down steel billet.

The technical scheme that its technical matters that solves the utility model adopts: above four set of wheels of steel billet transport trolley and between the vehicle frame, four corresponding resilient supporting unit (accompanying drawings 2 are installed symmetrically, 3), each resilient supporting unit comprises a rotary support, two springs, two spring guides, five hinged-support (accompanying drawings 1,4,5), set of wheels and rotary support are integral (accompanying drawing 1 by Bolt Connection, 5), lug is by bearing pin hinged (accompanying drawing 4) under the following lug of rotary support and the vehicle frame, bearing pin is by locating clamp plate and screw retention thereof, two upper lug of rotary support respectively with the lug of two spring guide one ends with articulation bolt hinged (accompanying drawing 5), two the lug articulation bolts hinged (accompanying drawing 4) above the lug of two spring guide other ends and the vehicle frame.

Vehicle frame is welded with down 4 of lugs symmetrically along the side-lower of track alignment, 8 of upper lug.Corresponding to each resilient supporting unit, vehicle frame is welded with the lug that resilient supporting unit is installed, one of below, two of tops along the side-lower of track alignment.

Each rotary support is useful on a side-lower lug and two top lugs of hinge mounted.On each resilient supporting unit, two springs and two spring guides are arranged between vehicle frame upper lug and rotary support upper lug, spring housing is on spring guide, and the spring guide horizontal direction is placed (accompanying drawing 1).

Set of wheels is placed on the rail, not motion on the vertical direction.Spring horizontal is arranged and has been reduced the transport trolley height overall, and four elastic support means of vehicle frame below symmetric arrangement, rotary support lug and vehicle frame lug and guide rod lug carry out that the bearing pin direction is stuck when hinged, be under the rotary support under lug and the vehicle frame between the lug between (accompanying drawing 4), rotary support upper lug and the spring guide lug under (accompanying drawing 5), spring guide other end lug and the vehicle frame between the lug (accompanying drawing 4) all are free-running fits along the bearing pin direction, make swing perpendicular to track alignment do not take place in the vehicle frame sinking process.When steel billet impacted the transport trolley upper table surface, vehicle frame and lug thereof sank, and around lug bearing pin rotation down, rotary support upper lug compression spring has played buffer action (accompanying drawing 1) together for rotary support and set of wheels.

The invention has the beneficial effects as follows, when weight-lifting equipment produces impact with a piece ground of steel billet let-down to the transport trolley table top, vehicle frame has elasticity to sink, and has improved the force-bearing situation of transport trolley vehicle frame greatly, has reduced the manufacturing cost and the operation energy consumption of steel billet transport trolley deadweight, transport trolley.

Specific implementation method

Shown in Figure 2, the transport trolley below has been arranged four resilient supporting units and the set of wheels that connects with it symmetrically.100T steel billet transport trolley main dimension is: wheel diameter D=φ 800mm, ride face length L=12000mm, ride face width B=2500mm, overall height H=2000mm, the identical B1=1435mm of resilient supporting unit transverse pitch, wheelspan T=8000mm with the rail square, spring guide spacing B2=400mm, shown in Figure 1, rotary support lower link point and wheel center horizontal throw L1=840mm, rotary support upper link point and wheel center perpendicular separation H1=880mm.

Each resilient supporting unit is assembling like this: at the front and back of vehicle frame (1) side-lower the resilient supporting unit corresponding position is installed and is welded with four following lugs, eight upper lug (Fig. 1,2,3).At first set of wheels (11) is connected into one (Fig. 1,5) by bolt (10), locating piece (12) with rotary support (6).The side-lower of rotary support (6) has a lug, and there are two lugs the top, and its side-lower lug and vehicle frame (1) lug down are hinged with bearing pin (8), with locating clamp plate (9) and screw (7) fixed pin shaft (8) (Fig. 4 bottom).Two springs (4) of each resilient supporting unit are enclosed within respectively on two spring guides (3), the upper lug of one end of spring guide (3) and vehicle frame (1) articulation bolt I (2) hinged (Fig. 4 top), the upper lug of the other end of spring guide (3) and rotary support (6) articulation bolt II (5) hinged (Fig. 5 top).Spring (4) and spring guide (3) horizontal positioned.

Rotary support (6) down lug and vehicle frame (1) down between the lug, between rotary support (6) upper lug and spring guide (3) lug, spring guide (3) other end lug and vehicle frame (1) descend between the lug along the bearing pin direction all is free-running fits, make swing perpendicular to track alignment does not take place in the vehicle frame sinking process.

By the position between horizontal location piece and perpendicular positioning piece (12) adjustment four set of wheels (11) and the rotary support (6), guarantee four wheel tread summits in a plane, the direction along ng a path front and back wheel is on a line, and online being parallel to each other of front and back wheel, the wheel transverse distance is consistent with gauge.After adjusting, two horizontal location pieces and two perpendicular positioning pieces (12) all were welded on the rotary support (6) with each set of wheels had, were the set of wheels reference for assembling with this locating piece during later change of wheels.
