Abstract
The utility model discloses the anti roll device on hoisting crane that a kind of production efficiency and safety factor can both improve.Anti roll device on hoisting crane, include trolley frame table top, sling upper rack, also include cable drum, cycloidal pin retarder, torque motor, leading sheave group, steel rope, four cable drums be rotatably connected under trolley frame table top are located at four angles of trolley frame table top, cable drum is connected with torque motor output shaft by cycloidal pin retarder, the steel rope be located on cable drum is connected with sling upper rack by the leading sheave group be rotatably connected under trolley frame table top, and sling upper rack is suspended on steel rope lower end.The utility model effectively can reduce the amplitude of fluctuation of suspender, enhances productivity and safety factor.
Description
Technical field
The utility model relates to hoisting crane, the anti roll device particularly on hoisting crane.
Background technology
Hoisting crane is when handling goods, due to the change of its speed and the impact of external interference factor, suspender in lifting, often there is all around in decline process and to swing back and forth phenomenon, the operating skill really up to the mark by driver can overcome all around dancing when lifting speed is low, and the driver of operating skill difference controls to get up just to have certain difficulty.Production efficiency can be made to reduce when lifting speed is low, wanting to enhance productivity just needs to improve lifting speed, and lifting speed crosses conference makes the suspender all around phenomenon that swings back and forth more serious.When suspender amplitude of fluctuation is excessive, safety factor will reduce, and safety factor reduces the safety misadventure probability of occurrence caused and will improve.
Summary of the invention
The technical matters that the utility model solves is to provide the anti roll device on hoisting crane that a kind of production efficiency and safety factor can both improve.
The technical solution of the utility model completes like this, anti roll device on hoisting crane, include trolley frame table top, sling upper rack, also include cable drum, cycloidal pin retarder, torque motor, leading sheave group, steel rope, four cable drums be rotatably connected under trolley frame table top are located at four angles of trolley frame table top, cable drum is connected with torque motor output shaft by cycloidal pin retarder, the steel rope be located on cable drum is connected with sling upper rack by the leading sheave group be rotatably connected under trolley frame table top, sling upper rack is suspended on steel rope lower end.
Further preferred embodiment, described four cable drums are symmetrical arranged in all around under trolley frame table top.
Further preferred embodiment, described be connected with sling upper rack the point of connection of four steel ropes on sling upper rack in left and right, front and back are symmetrical arranged.
Further preferred embodiment, the width between described four steel rope lower ends is less than the width between its upper end.
Further preferred embodiment, sling upper rack is in uphill process, and the angle [alpha] between the plane at steel rope and sling upper rack place changes between 60-75 degree.
Further preferred embodiment, sling upper rack is in decline process, and the angle [alpha] between the plane at steel rope and sling upper rack place changes between 75-60 degree.。
Technique effect of the present utility model is: in operation process, by being continued energising to torque motor, all the time steel rope tension force is given, suspender is in process of rising or falling, all the time strained condition is in for outstanding four steel ropes holding sling upper rack, an application force can be produced when suspender rocks to some directions, because reciprocal steel rope is in strained condition all the time, can to suspender reciprocal antagonistic force, when application force and antagonistic force are cancelled out each other, prevent the swing of suspender, suspender is made to be in stabilized conditions, effectively can reduce the amplitude of fluctuation of suspender, thus while can be implemented in and enhancing productivity, safety factor also increases accordingly, serve certain stabilizing efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model portion face structural representation.
Fig. 2 is the connection structure schematic diagram between cable drum in Fig. 1, cycloidal pin retarder, torque motor.
Detailed description of the invention
