Embodiment Construction

[0023] The invention is like Figure 1-3 As shown, it includes a frame 1. The top of the frame 1 is provided with a reel 3 driven by a motor 2, a fixed pulley block 4 is provided in the frame 1, and a balance pulley 5 is provided at the bottom of the frame. A movable pulley block 6 is provided under the frame, and both ends of the reel are respectively provided with support shafts 10, the motor 2 is connected to a support shaft of the reel through a reducer 9, and the other support shaft of the reel is connected to the machine through a bearing seat 11. On the rack, the reel can rotate reliably;

[0024] The two ends of the reel 3 are respectively wound and connected with the movable pulley group 6, the fixed pulley group 4 and the balance pulley 5 through the same wire rope 7; the connection sequence of the wire rope is: reel→movement pulley group→fixed pulley one→movement pulley group→balance pulley→ Movable pulley group→fixed pulley 2→moving pulley group→reel.

Abstract

The invention relates to the field of water conservancy machinery, in particular to a linear pulley-block hoist. Under the premise that original working performance keeps unchanged, the width of a service bridge can be reduced, the structure is compact, and installation is convenient. The linear pulley-block hoist comprises a rack, a winding drum driven by a motor is arranged at the top of the rack, and a fixed pulley block is arranged in the rack. A balance pulley is arranged at the bottom of the rack, a movable pulley block is arranged below the rack, and the two ends of the winding drum are each connected with the movable pulley block, the fixed pulley block and the balance pulley through the same steel wire rope in a wound mode. The center lines of the winding drum, the fixed pulley block and the movable fixed pulley block are parallel to one another and located on the same plane. The linear pulley-block hoist is compact in layout, attractive and convenient to install and convey.

Description

Technical field [0001] The invention relates to the field of water conservancy machinery, in particular to a linear pulley block hoist. Background technique [0002] The hoist is used in various large-scale water supply and drainage, water conservancy and hydropower projects to realize the control of various large and medium-sized cast iron gates and steel gates to open and close. In the prior art, the gate hoist is generally composed of a motor, a brake, a coupling, a reducer, a reel device, a wire rope, a pulley block, etc., such as Figure 4-5 As shown, the fixed pulley is usually installed on one side of the drum, and the fixed pulley and the drum are arranged side by side, and the overall width is relatively large. In this way, a large working hole needs to be opened on the working bridge to realize the operation and use of the whole machine. . As a result, the width of the working bridge is large, the manufacturing cost is high, and the manufacturing cost of the entire gate...
