Abstract
The utility model relates to the technical field of balance cranes, and in particular relates to a balance crane driving device. A balance crane driving rod (1) is provided with a coupler which comprises an upper coupler (9) and a lower coupler (11), wherein the upper coupler (9) is in a push-in type structure, and the upper coupler (9) and the lower coupler (11) are connected by a dowel-pin nylon rod (10); a pressing cover (8) is arranged on one side of the upper coupler (9), and one side of the pressing cover (8) is locked by a locking nut (7); and a plane bearing (12) is arranged on one side of the lower coupler (11), and a cap (13) is arranged on the end of the plane bearing (12). The dowel-pin nylon rod is used for transferring the torque, and when a crane is overloaded, the turning part of the middle nylon rod is broken, thereby performing a safety protection effect. Additionally, a driving (copper) nut is in a split type and is fixed by the pressing cover, and when the driving copper nut is worn, a fastening screw rod on the pressing cover is removed so as to take out the worn driving copper nut. The balance crane driving device has the advantage of convenience in maintenance, and the whole balance crane driving rod device does not need to be removed.
Description
Technical field
The utility model relates to the balance crane technical field, specifically relates to a kind of balance crane driving device.
Background technology
At present, in the copper material processing technique field, the main balance crane that adopts of copper volume lifts by crane, balance crane driving device of the prior art, and its structure sees also Fig. 1, mainly has following technological deficiency:
The balance crane coupler adopts spring to transmit moment of torsion, and plays the safety guard-safeguard effect, during use and cap be prone to looseningly, deflection of spring skids, maintenance time is longer, and spring protection effect difficulty reaches the expection result of use.
Balance crane transmission copper nut is cylindrical structural, changes after needing after the wearing and tearing to remove the feed screw nut, and problems such as removal time, maintenance load is bigger, produces considerable influence to producing.
Summary of the invention
At the technical matters that exists in the prior art, the utility model provides a kind of balance crane driving device, has eliminated the coupler skidding, convenient for maintaining, and the labour intensity of reduction service worker promotes and produces operational paradigm.
To achieve these goals, the technical scheme of employing is as follows:
A kind of balance crane driving device, it is characterized in that, has balance crane drive link (1), described balance crane drive link (1) is provided with coupler, described coupler comprises upper coupling (9) and the following coupler (11) that is plug in construction, connect by pin nylon rod (10) between described upper coupling (9) and the following coupler (11), a side of described upper coupling (9) is provided with gland (8), and described gland (8) one sides are by fastening screw nut (7) locking; A described side of coupler (11) down is provided with surface bearing (12), and the end of described surface bearing (12) is provided with and cap (13).
Further, described balance crane drive link (1) is provided with transmission copper nut (6), the outside of described transmission copper nut (6) be provided with can be outside transmission copper nut (6) nut seat (4) of side shifting, one side of described transmission copper nut (6) is provided with nut seat gland (3), is connected by fastening screw (2) between described nut seat gland (3) and the nut seat (4).
Comparatively perfect is that described nut seat (4) is provided with nut set pin (5).
The utility model balance crane driving device transmits moment of torsion by the pin nylon rod, when lifting overloads, and the fracture of middle nylon rod turning position, thus play the safety guard-safeguard effect.Simultaneously, transmission (copper) nut is dissection type, fixes by gland, when the transmission copper nut weares and teares, removes the fastening screw on the gland, can take out the transmission copper nut of wearing and tearing, and is easy to maintenance, need not remove whole machine balancing and hang drive pole device.
