[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-3 As shown, a winch for construction engineering includes a support plate 1, a rubber pad 2, a winch device 3, a power distribution control box 4, and a gear box 5. Two rubber pads 2 are glued to both sides of the support plate 1, the winch device 3 is welded to the rear of the top of the support plate 1, the power distribution control box 4 is welded to the right side of the front end of the top of the support plate 1, and the gear box 5 is welded to the left side of the top of the support plate 1.

[0016] The hoisting device 3 includes a side plate 6, an electromagnetic brake 7, a reel 8, a speed measuring probe 9, a driven wheel 10, a center wheel 11, a center wheel shaft 12, a gear box housing 13, a motor base 14, a DC motor 15, and a driving wheel 16. The reel 8 is axially connected between the two side plates 6. The electromagnetic brake 7 is welded on the upper inner side of the right side plate 6. The speed measuring probe 9 is welded on the top of the right side plate 6. The driven wheel 10 is welded on the left side of the reel 8 axle. The center wheel 11 is axially connected to the center of the inner side of the gear box housing 13 through the center wheel shaft 12. The DC motor 15 is welded on the top of the motor base 14. The driving wheel 16 is welded on the front end of the DC motor 15. The driven wheel 10 and the driving wheel 16 are meshed with the center wheel 11. The electromagnetic brake 7 is electrically connected to the speed measuring probe 9 and the power distribution control box 4.

[0017] The power distribution control box 4 includes a fixing plate 17, screw holes 18, a film capacitor 19, a circuit board 20, a control processor 21, and an IGBT driving circuit board 22. Four screw holes 18 are equidistantly provided at the four corners of the fixing plate 17. The film capacitor 19 is welded to the left front side of the fixing plate 17. The circuit board 20 is bolted to the right front side of the fixing plate 17. The control processor 21 is welded to the upper left corner of the front side of the circuit board 20. The IGBT driving circuit board 22 is welded to the right front side of the circuit board 20.

[0018] The working principle of the utility model is as follows: after the hoisting device is turned on, the speed measuring probe monitors the speed of the reel. When the reel stalls, the speed measuring probe sends a signal back to the power distribution control box, and the power distribution control box quickly starts the electromagnetic brake to forcibly lock the reel axle and stop the reel from rotating, thereby ensuring the safety of lifting.

[0019] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
