Description
Technical Field
The utility model relates to a hoist technical field, especially a quiet atress formula electric block trolley.
Background
Electric hoist type crane trolleys are widely used in industrial cranes, for example, double-beam cranes are widely used. For a double-beam crane, the trolley is generally welded by two end beams, a plurality of cross beams and a plurality of small rib plates to form a rigid frame and at least four wheels, but as the trolley is a non-statically determinate stress structure, the practical findings show that once the geometric accuracy of bridge frame manufacturing, steel rail installation, trolley frame manufacturing and wheel installation is not satisfactory, the four wheels are not aligned (for example, a certain wheel is too high), the problems of uneven wheel pressure, three-point landing and the like occur, and the trolley becomes unstable. A hinged shaft three-fulcrum type electric hoist hoisting trolley with pure static stress is designed, the problem of uneven wheel pressure is solved, the safety is not good enough, the requirement on a vibration and noise reduction structure is higher, and damage is easy to occur in product transportation and transportation.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein.
Referring to fig. 1 and 2, the statically determinate stress type electric hoist trolley comprises frame devices which are arranged on the left side and the right side in a split mode, the frame devices can run on steel rails, and wheels 1 are arranged on the frame devices. A connecting beam 2 is arranged between the frame devices, and an electric hoist 21 is arranged on the connecting beam 2 to form a main frame of the trolley device.
The frame device comprises a rigid connection cross beam frame 3 on one side and a hinged cross beam frame 4 on the other side, the rigid connection cross beam frame 3 is fixedly connected with the connecting beam 2, the hinged cross beam frame 4 is connected with the connecting beam 2 through a hinge pin 5, namely the rigid connection between the rigid connection cross beam frame 3 and the connecting beam 2 is not movable any more, and the hinged cross beam frame 4 and the connecting beam 2 can swing along the hinge pin 5.
Referring to fig. 2 and 3, a safety bolt 6 is further arranged between the hinged cross beam frame 4 and the connecting beam 2, and a damping block 7 is sleeved on the safety bolt 6. The design of the damping block ensures that the position of the articulated cross beam frame 4 of the trolley has enough flexibility to adjust the contact condition with the steel rail, can completely solve the problems of uneven wheel pressure and three-point landing and improves the stability of the trolley. The damping mass 7 retains a suitable pre-compression amount, so that the damping mass 7 can better absorb vibration energy of the whole trolley and reduce mechanical noise. The safety bolt 6 can improve the safety of the trolley frame, and even if the hinge pin 5 is broken and falls off, the safety bolt 6 can achieve the protection effect without causing serious safety accidents.
Alternatively, the damping block 7 may be made of rubber or polyurethane material having good plasticity, good vibration absorption and a certain strength. Four safety bolts 6 can be adopted, connecting holes are drilled corresponding to four corners to install the safety bolts 6, and the axial lead of the connecting holes is as close as possible to the vertical plane of the hanging load center of the electric hoist 21 so as to reduce the torque applied to the connecting beam 2.
When the product is transported, four safety bolts 6 can be screwed down temporarily and uniformly, and the hinged cross beam frame 4 cannot shake along the axis of the hinge pin 5 to damage the crane trolley.
