Detailed description of the invention
The technical matters solved to make the present invention, the technical scheme of employing, the technique effect easy to understand obtained, below in conjunction with concrete accompanying drawing, be described further the specific embodiment of the present invention.
With reference to figure 1, the invention provides the adaptive mechanism in a kind of transport trolley driver element, this adaptive mechanism is the connection structure between transport trolley vehicle frame and transport trolley drive wheel, it comprises driving upper bracket 1 and drives lower bracket 2, described driving lower bracket 2 is rotatably connected on the below driving upper bracket 1, constitutes the support housing of adaptive mechanism of the present invention.
Wherein, driving upper bracket 1 for being fixedly connected with transport trolley vehicle frame, driving lower bracket 2 for being fixedly connected with the drive wheel bracket of transport trolley.In the embodiment that the present invention one is concrete, with reference to figure 4, described driving upper bracket 1 comprises the upper substrate 15 for being fixedly connected with transport trolley vehicle frame, and be positioned at the first bending part 16 of upper substrate 15 both sides, this first bending part 16 can be one-body molded with upper substrate 15, such as, can be the downward bending at upper substrate 15 edge; Described driving lower bracket 2 comprises infrabasal plate 10, and is positioned at the second bending part 11 of infrabasal plate 10 both sides, and this second bending part 11 can be one-body molded with infrabasal plate 10, such as, can be the upwards bending at infrabasal plate 10 edge, with reference to figure 3.When installation, described first bending part 16 and the second bending part 11 are rotatably connected by rotating shaft 25, thus achieve driving upper bracket 1 and drive being rotationally connected between lower bracket 2, the two can be relatively rotated along rotating shaft 25, when being in state of equilibrium, infrabasal plate 10 keeping parallelism basic with upper substrate 15.
Mode well-known to those skilled in the art can be adopted first bending part 16, second bending part 11, rotating shaft 25 to be installed, in an embodiment of the present invention, one end of described rotating shaft 25 and the second bending part 11 Flange joint, to avoid the situation of the rear bad welding of quenching, and the right alignment at two ends can be ensured preferably.The other end of rotating shaft 25 penetrates in the through hole 17 of the first bending part 16, with reference to figure 2.For the ease of assembling, the through hole 17 of described first bending part 16 takes the shape of the letter U, the through lower end to the first bending part 16.Install time, first by one end of rotating shaft 25 together with the sidewall Flange joint of the second bending part 11, then the opening part of rotating shaft 25 from through hole 17 is pressed into, and adopts fastener to be fixed.Further preferably, lining 8 is also provided with in the through hole 17 of described first bending part 16, to avoid the wearing and tearing between rotating shaft 25 and through hole 17.
Adaptive mechanism of the present invention, also comprises the multiple springings being pressed in advance and driving between upper bracket 1, driving lower bracket 2, specifically incites somebody to action, be provided with the springing of multiple precompressed between upper substrate 15 and infrabasal plate 10.In the present invention's specific embodiment, springing adopts spring 6, can certainly adopt other springing well-known to those skilled in the art, is now described for two springs 6.
One end of spring 6 connects upper substrate 15, and the other end connects infrabasal plate 10, and is in preloading condition.Wherein, two springs 6 are separately positioned on the both sides of infrabasal plate 10 pivot center, and particularly, two springs 6 can be symmetrical with pivot center, also can be arranged in the diagonal of infrabasal plate 10.When the quantity of spring 6 is more, need ensure at least respectively there is a spring 6 in the both sides of infrabasal plate 10 pivot center, preferably, the total dynamics of precompressed of pivot center both sides spring is consistent, to ensure that infrabasal plate 10 and upper substrate 10 keep balancing when initial condition.
Adaptive mechanism of the present invention, driving the lower end mounting transport vehicle drive wheel of lower bracket 2, through roughness pavement, such as road surface is high on one side, and when road surface is low, infrabasal plate 10 can deflect, the one end turning to road surface low by one end that road surface is high, finally make two drive wheels produce differential seat angle, thus remain wheel and the earth surface of transport trolley, make transport trolley bench board remain horizontality; In the traveling process of transport trolley, remain that four-wheel grabs ground, transport trolley is run more steady, controllability is stronger, and different from traditional non-bearing driver element, can provide larger earth-grasping force and power-handling capability.
Adaptive mechanism of the present invention, the predetermincd tension that spring produces by compression afterwards can bear pressure suffered in rotating shaft 25.That is, the unidirectional large stress that rotating shaft 25 is received becomes two-way little stress, pressure when greatly reducing full-load run suffered by rotating shaft, and two-way little reversed of stress frequency is extremely low, reverse stress can be ignored the destruction of material, thus it is stressed to reduce rotating shaft 25, reduces fret wear and destruction, greatly improve the service life of rotating shaft and lining.
Those skilled in the art can adopt existing structure to carry out mounting spring 6, in the present invention, described infrabasal plate 10 are provided with the spring guide pillar 13 for being socketed spring 6 lower end; Described upper substrate 15 is provided with adjustment screw 9, and this adjustment screw 9 screws in the lower end of upper substrate 15 from the upper end of upper substrate 15, is fixed with the spring spool 5 penetrated for spring 6 upper end at the lower end of described adjustment screw 9.When installing, the lower end of spring 6 is enclosed within spring guide pillar 13, and upper end penetrates in spring spool 5.Can rise or decline by operating spring sleeve 5 by rotating adjustment screw 9, thus reach the effect of regulating spring 6 predetermincd tension, certainly, in order to prevent the play voluntarily adjusting screw 9, adjustment screw 9 also can arrange jam nut 4, and this belongs to existing technology, no longer illustrates at this.
Adaptive mechanism of the present invention, the lower end of described infrabasal plate 10 is also provided with the supporting disk 3 for fixing transport trolley drive wheel bracket, this supporting disk 3 has the inner chamber of hollow, the drive wheel bracket of transport trolley is rotationally connected by this supporting disk 3, further, the sidewall of described supporting disk 3 is also provided with stop block 7, and this stop block 7, for coordinating with the corresponding component on mounting bracket, prevents the transition of drive wheel bracket from rotating.
For ensureing that this adaptive mechanism can keep higher rigidity and reliability under large load (such as 300kg), improve its safety performance and service life, be provided with multiple triangle between described infrabasal plate 10 and the second bending part 11 and strengthen perpendicular muscle 14, described triangle is strengthened perpendicular muscle 14 and is extended to infrabasal plate 10 for connecting the position of supporting disk 3 from the second bending part 11 always.Certainly, also can arrange strip shape reinforced rib 12 at the edge of infrabasal plate 10, greatly improve rigidity and the safety performance of sheet metal component, service life is greatly improved.
The present invention is by preferred embodiment having carried out detailed explanation.But, by studying carefully above, concerning the change of each embodiment with to increase be apparent for one of ordinary skill in the art.Being intended that these changes all and increasing of applicant has all dropped in scope that the claims in the present invention protect.
