Abstract
The utility model discloses a transmission damping device of a lifter. The transmission damping device of the lifter consists of a transmission mechanism, connecting transmission plates and cages, wherein the connecting transmission plates and the cages are firmly connected through high-strength bolts; middle belleville springs are respectively arranged between the transmission plates and the cages; and the corresponding high-strength bolt between the corresponding transmission plate and a nut of the corresponding high-strength bolt is sheathed with a cushion collar, an annular pressure sensor and a belleville spring from top to bottom. The transmission damping device of the lifter has the characteristics that the annular pressure sensors are adopted, so that the lifter safely and efficiently runs; the manufacturing process is simplified; load measuring equipment of the lifter is more accurate; the accuracy of mesh of gear racks is ensured; the vibration phenomenon is thoroughly eliminated; and the problem that pin shaft sensors can be easily broken is solved.
Description
Technical field
The utility model belongs to the construction machine technical field, especially relates to a kind of lifter driving mechanism damping device.
Background technique
The building hoist of present domestic use, transmission frame is rigidly connected with the many employings of being connected of cage, and manufacturability is relatively poor, does not have preferably buffer function; Because single ears fork connects and fabrication error occurs, interferes, make the reflection of sensor bearing pin insensitive, error in dipping is large; Driving mechanism is not operational system independently, and the vibration of driving mechanism and cage is transmitted mutually, causes easily resonance.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide a kind of adopt annular pressure sensor, lift safety and efficiently move, simplified production process, make the lift load measuring device more accurately, guarantee the accuracy of mesh of gear rack, thoroughly solve the lifter driving mechanism damping device of oscillation phenomenon and bearing pin sensor easy-rupturing.
The purpose of this utility model is to realize like this, a kind of lift transmission damping device, formed by driving mechanism, driver plate and cage, be characterized in that driver plate and cage are connected firmly by high-strength bolt, butterfly spring in the middle of being provided with between connection for transmission plate and cage, overlapping from top to bottom on the high-strength bolt between the nut of connection for transmission plate and high-strength bolt has cushion collar, annular pressure sensor, belleville spring.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts connection for transmission plate and cage to be connected firmly by high-strength bolt, be provided with butterfly spring between connection for transmission plate and cage, overlap from top to bottom on the high-strength bolt between the nut of connection for transmission plate and high-strength bolt cushion collar, annular pressure sensor, belleville spring are arranged, with belleville spring cage is connected with driver plate by cushion collar with high-strength bolt, realized the secondary damping, made in the different situation of cage carrying capacity damping effect obvious; Placement of the present utility model makes the bore hole of driver plate bolt hole prior art change boring into, greatly reduces processing request; Replace forging bolt with high-strength bolt, simplified production technology, the generalization degree of part is high, replaces the pin axle type sensor with the annular pressure sensor, has overcome the problem of pin axle type sensor because of the remitted its fury easy-rupturing, has effectively guaranteed the lift safe operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is a kind of structural representation at high-strength bolt of the present utility model position.
Embodiment
Embodiment, a kind of lift transmission damping device, with reference to Fig. 1, Fig. 2, that driving mechanism 1 is installed on the driver plate 2, and being arranged on cage 7 tops, connection for transmission plate 2 and cage 7 are connected firmly by high-strength bolt 3, butterfly spring 8 in the middle of 7 of connection for transmission plate 2 and cages are provided with, overlapping from top to bottom on the high-strength bolt 3 between the nut of connection for transmission plate 2 and high-strength bolt 3 has cushion collar 4, annular pressure sensor 5, belleville spring 6, and this consists of a kind of structure of the present utility model.
