Description
Technical field
The utility model relates to the Special type transportation vehicle field of heavy duty, is specially a kind of elasticity walking structure for transport trolley or trailer.
Background technology
Many steel mills employing one easily trackless scrap steel chute transport vehicle carries out converter steel scrap charging technology.This scrap steel chute transport vehicle adopts band lifting the 5th wheel tractor to mix the tractor truck of special hook connecting connection mechanism as scrap steel chute transport vehicle, the trailer of its hopper transport trolley is then original scrap steel trough is set up running mechanism and supporting leg hanging mechanisms convert hopper trailer, and can mount very easily between tractor truck, shirk, and arbitrarily can mate connection, efficiency is very high, be steel mill's converter steel scrap reinforced well have bad luck equipment.
The running mechanism of this hopper trailer above-mentioned generally adopts rigid suspended and band tyre to add wheel mount structure composition, and its major cause is band tyre puncture-resistant, and driving safety is high; Rigid suspended bearing capacity is large, and overload capacity is strong.But the condition of road surface of some steel mill is poor, and the moving velocity of driver scrap steel chute transport vehicle quickly, and this just causes, and its band tyre is subject to impacting greatly, heating is large, easily produces the phenomenons such as knocking over, greatly reduces service life; Meanwhile, rigid suspended is also the impact being subject to excess, and its connection structure position easily produces damage, and fault rate is higher, have a strong impact on production efficiency and working service cost remain high.
Summary of the invention
The purpose of this utility model is, provides a kind of resilient suspension of hopper trailer to overcome the defect existing for existing trailer traveling gear.
In order to achieve the above object, the utility model is achieved in that
For the elasticity traveling gear of transport trolley or trailer, it comprises two large rigidity longerons, and the three axle springs be connected with longitudinal beam welding hang, hang with three axle springs the axletree be connected, and are located at the major diameter band tyre on axletree; Also comprise center suspension device and longeron spring stopper; Described center suspension device comprises box body, be positioned at the axle bed of box body both sides and cross the bearing pin of axle bed, box body, the middle part symmetry of two longerons has axis hole, center suspension device is located at the middle part of two longerons, and both are articulated and connected through after the axis hole on the axle bed of center suspension device, longeron and box body by bearing pin; The top of box body is directly welded to connect with the device such as the hopper installed needed for transport trolley or trailer; Longeron spring stopper comprises pilot bar and is through at the spring in pilot bar; Described pilot bar two ends are fixedly connected with devices such as hoppers.
The described elasticity traveling gear for transport trolley or trailer, is provided with horizontal connecting rod between two corresponding springs of longeron hang.
The utility model adopts three axle springs suspensions, axletree is used as its primary resilient load-carrying unit, have employed center suspension device simultaneously, large rigidity longeron is used as three axle springs and hangs carrying transition between hopper body, and uniform load is distributed to three axletrees.In addition, have employed the both sides that major diameter band tyre is arranged on axletree, as traveling load-carrying unit; So, provide enough bufferings when vehicle travels, the collision between each parts is remained in tolerance range, can extend the traveling life-span of car load.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model center suspension device.
Fig. 3 is scheme of installation of the present utility model.
Detailed description of the invention
The utility model is further illustrated below by way of specific embodiment.
As shown in Figure 1, Figure 2 and Figure 3, a kind of elasticity traveling gear for transport trolley or trailer, it comprises two large rigidity longerons 1, and the three axle springs be welded to connect with longeron 1 hang 2, hang 2 axletrees be connected 4 with three axle springs, are located at the major diameter band tyre 3 on axletree 4; Also comprise center suspension device device 5 and longeron spring stopper; Described center suspension device device comprises box body 5, be positioned at the axle bed 9 of box body 5 both sides and cross the bearing pin 6 of axle bed 9, box body 5, the middle part symmetry of two longerons 1 has axis hole, center suspension device device is located at the middle part of two longerons 1, and both are articulated and connected through after the axis hole on the axle bed 9 of center suspension device device, longeron 1 and box body 5 by bearing pin 6; The top of box body 5 is directly welded to connect with the device 10 such as the hopper installed needed for transport trolley or trailer; The spring 8 that longeron spring stopper comprises pilot bar 7 and is through in pilot bar 7; Described pilot bar 7 two ends are fixedly connected with devices 10 such as hoppers.
The described elasticity traveling gear for transport trolley or trailer, is provided with horizontal connecting rod between two corresponding springs of longeron hang.
The utility model adopts three axle springs suspensions, axletree is used as its primary resilient load-carrying unit, have employed center suspension device simultaneously, large rigidity longeron is used as three axle springs and hangs carrying transition between hopper body, and uniform load is distributed to three axletrees.In addition, have employed the both sides that major diameter band tyre is arranged on axletree, as traveling load-carrying unit; So, provide enough bufferings when vehicle travels, the collision between each parts is remained in tolerance range, can extend the traveling life-span of car load.
