Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, be described in further detail detailed description of the invention of the present utility model, object helps those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme, and contribute to its enforcement.
As shown in Figures 1 and 2, the shock absorbing apparatus of this electric pallet truck, comprise drive installation plate 15, driver element installed by drive installation plate 15, driver element connects drive wheel, and drive installation plate 15 front end is provided with connecting rod mechanism, and the vehicle frame 1 of connecting rod mechanism and electric pallet truck is flexibly connected, connecting rod mechanism can centered by the attachment point on vehicle frame 1, and connecting rod is radius synchronous rotary; Drive installation plate 15 rear end is provided with stage clip 16, and stage clip 16 can provide the wheel load of acting in opposition force compensating drive wheel on road surface of jolting; Stage clip 16 top is provided with the regulating mechanism regulating stage clip 16 thrust.Jolting on road surface, drive installation plate 15 is under connecting rod mechanism effect, can centered by the attachment point on vehicle frame 1, the connecting rod of connecting rod mechanism is that radius rotates, simultaneously under the antagonistic force of stage clip 16, and the wheel load of energy effective compensation drive wheel, prevent from skidding because of the change of drive wheel wheel load, the phenomenon such as hard steering, also reduce road surface greatly to the impact of vehicle, realize shock-absorbing, improve the driver comfort of car load.
For reaching better shock-proof effect, the thrust of stage clip 16 needs to adjust according to actual working environment and real work duration, and the thrust of stage clip 16 can be adjusted by regulating mechanism.For the defect of prior art, the thrust of preferred stage clip 16 is regulated and is realized by adjusting bolt 7, and the adjustment of adjusting bolt 7 not only operates more for convenience, and adjustment is comparatively directly perceived, is convenient to observe, has the advantage that adjustment is quick, easy to operate.Concrete, regulating mechanism comprises the pressing plate 5 be connected with stage clip 16 and the adjustment limiting stopper 6 be located on vehicle frame 1, also comprises the adjusting bolt 7 for connecting pressing plate 5 and adjustment limiting stopper 6.Pressing plate 5 is connected with stage clip 16, adjustment limiting stopper 6 is fixed on vehicle frame 1, the connection location of adjustment adjusting bolt 7 on adjustment positioning plate 6, adjusting bolt 7 makes pressing plate 5 to move or moves down, stage clip 16 has different amount of compressions under the pressuring action of pressing plate 5, namely there is different thrusts, and then provide enough application forces for driver element, avoid drive wheel to skid and car load shakes.
The number of adjustment limiting stopper 6 can adjust according to actual needs, as shown in Figure 6, as a kind of embodiment, preferably adjustment limiting stopper 6 is one, adjustment limiting stopper 6 is provided with tapped bore 19, and adjusting bolt 7 crimps with connecting bore 20 set on pressing plate 5 mutually through tapped bore 19.Adjusting bolt 7 realizes fixing by the tapped bore 19 on adjustment limiting stopper 6, and adjusting bolt 7 compresses with connecting bore 20 and contacts, and adjusting bolt 7 can realize freely rotating in connecting bore 20; By adjustment adjusting bolt 7 and the connection location adjusting limiting stopper 6, adjusting bolt 7 makes pressing plate 5 to move or moves down, and then stage clip 16 has different amount of compressions, namely has different thrusts.
When adjustment limiting stopper 6 is one, balanced for ensureing the amount of compression of each stage clip 16, preferred connecting bore 20 is located at the medium position of pressing plate 5, is beneficial to like this and ensures that the power that adjusting bolt 7 acts on pressing plate 5 is balanced; Further preferably adjust tapped bore 19 line of centers on limiting stopper 6 and vehicle frame 1 centerline parallel, ensure that the power that pressing plate 5 pairs of stage clip 16 both sides apply is balanced further.
Adopt single adjusting bolt 7, the amount of compression of each stage clip 16 cannot be regulated respectively, so very high to the welding requirements of adjustment limiting stopper 6, as adjusted tapped bore 19 line of centers on limiting stopper 6 and the requirement of vehicle frame 1 centerline parallel degree out of reach, often occur that adjusting bolt 7 tilts, cause the power difference that pressing plate 5 pairs of stage clip 16 both sides apply, the amount of compression of stage clip 16 is also just different, the stressed excessive driver element that may cause of stage clip 16 tilts, and then affects the work of drive wheel.
