Abstract
The utility model discloses a construction winch used for lifting heavy things during construction engineering, which comprises a framework, a motor, a reduction box and a rope drum. The rope drum is welded into a whole by an iron plate, a coupling used for connecting a motor shaft and an input shaft of the reduction box is of a disc shaft pin connection structure, the shaft pin can be divided into a taper pin and a cylindrical pin, which are matched with the tapered hole and the column hole respectively, a bearing hole cover on the reduction box is fastened on the outer side of the reduction box by a screw, and a sealing ring is arranged at the connection place. The utility model has advantages of light weight, material saving, energy saving, convenient installation and maintenance, low operating cost and applicability to small batch of diversified production without oil leakage to the reduction box and environmental pollution.
Description
Technical field
The utility model relates to a kind of electrodynamic type winch that is used for building engineering.
Background technology
Hoisting heavy is extensive use of the electrodynamic type winch in the building engineering, and this building whim mainly is made of frame, reel, motor, drop-gear box.Reel is an ironcasting in the existing winch, volume heaviness not only, and consumptive material, big energy-consuming, and also cost of manufacture is also higher, is not suitable for many variety production; Coupler in the winch between motor shaft and the drop-gear box input shaft adopts the disk connection structure with inside and outside gear ring, and not only installation and maintenance trouble, and in a single day indivedual tooth is damaged, and will change coupler, increases operating cost; In addition, the door in drop-gear box head bearing hole directly snaps in the half circle groove of upper and lower casing, also brings difficulty to installation and maintenance, and leakage of oil easily, causes environmental pollution.
The utility model content
The technical problems to be solved in the utility model is the weak point that overcomes existing electric winch, provide a kind of material-saving, energy-conservation, cost is low, and is and convenient for installation and maintenance, helps the building whim of environmental protection.
The technical solution of the utility model is: building whim comprises reel, motor, drop-gear box, motor shaft is linked to each other by coupler with the drop-gear box input shaft, drop-gear box is provided with the bearing hole door, improvements are that described reel is the integral solder part, described coupler is the disc shaft pin connected construction, in the drop-gear box outside, there is seal ring door and drop-gear box junction to described bearing hole door by screw retention.
Pivot pin is divided into two sections of tapered pin and straight pins in the above-mentioned coupler, matches with taper hole, the cylindrical hole of two disks respectively.
In the utility model, reel is welded into integral body with end plate again by the cylindrical shell that roll of steel plate is welded into, and the weight ratio ironcasting alleviates many, manufacture craft is simpler, and power drain is little during running, thus material-saving, energy-conservation, cost is low, and the product specification change easily, is more suitable for many kinds, small batch production.The coupler that connects motor shaft and drop-gear box input shaft adopts the disc shaft pin connected construction, and this pivot pin is divided into two sections of tapered pin and straight pins, match with the taper hole and the cylindrical hole of left and right disk respectively, not only convenient for installation and maintenance, can reduce tolerance clearance after the assembling, reduce wear, and after a certain pivot pin damages, as long as change single pivot pin, needn't change other part, save operating cost.In addition, in the drop-gear box outside, and there is seal ring the junction to drop-gear box head bearing hole door, makes its installing/dismounting very convenient by screw retention, again can leakage of oil, avoid environmental pollution.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As figure, motor 1, drop-gear box 3, reel 6 are installed on the frame 7.Reel 6 is welded into integral body after by the iron plate blanking.The coupler 2 that connects motor shaft and drop-gear box input shaft is the disc shaft pin connected construction, its pivot pin 2-2 is divided into two sections of tapered pin and straight pins, taper hole and cylindrical hole with left disk 2-1, right disk 2-3 matches respectively, and the small end of pivot pin conical section is strained by nut.In the drop-gear box outside, there is seal ring 5 door and drop-gear box junction to drop-gear box head bearing hole door 4 by screw retention.
Claims (2)
1, a kind of building whim, comprise reel, motor, drop-gear box, motor shaft is linked to each other by coupler with the drop-gear box input shaft, drop-gear box is provided with the bearing hole door, it is characterized in that described reel is the integral solder part, described coupler is the disc shaft pin connected construction, and in the drop-gear box outside, there is seal ring door and drop-gear box junction to described bearing hole door by screw retention.
2,, it is characterized in that in the described coupler that pivot pin is divided into two sections of tapered pin and straight pins, matches with taper hole, the cylindrical hole of two disks respectively by the described building whim of claim 1.
