Problems solved by technology
[0002] The screw type hoist currently in use, the lead screw or the screw is set vertically, and is divided into two working forms: nut rotation or lead screw rotation. Since the lead screw or the nut is directly connected with the gate, the two working forms are both There are the following disadvantages: the lead screw is too long, it is extremely inconvenient to manufacture, store, transport, install and maintain, and the height of the door opening is limited. At the same time, if the operation is not proper, the lead screw is easy to bend

Embodiment Construction
[0014] Accompanying drawing is a kind of specific embodiment of the present invention. figure 1 Middle: The vertical screw hoist is mainly composed of a power machine, a transmission transmission system, a screw, a nut, a machine base and a hand crank. The upper end of the screw is fixedly connected with the transmission part. Inside the body but not out of the body, the nut 14 is provided with a mechanical device, which is connected with the gate by the mechanical facilities and connectors matched therewith. The mechanical device located on the nut 14 is a movable pulley block 2 arranged symmetrically, and its movable pulley shaft 3 is fixedly connected with the nut 14 and the axis is vertical. The suspender 8 established at the connector wire rope end of the overmoving and fixed pulley block links to each other with the gate. The inner wall of the base 11 is provided with a symmetrical limiting groove 4, and the shaft end of the movable pulley shaft 3 corresponding thereto ...

The invention relates to an open-close machine for hydraulic gates, in particular to a vertical screw open-close machine. The vertical screw open-close machine mainly comprises an engine, a variable transmission system, a lead screw, a nut, a base and a handle, wherein the upper end of the lead screw is fixedly connected with a transmission component. The vertical screw open-close machine is characterized in that the lead screw is arranged in the engine and is not protruded out from the engine; and the nut is provided with a mechanical device and is connected with a connecting component and agate by mechanical facilities matched with the nut. The vertical screw open-close machine has the advantages that the problem that the lead screw is overlong is solved; the open-close machine is easyto manufacture, store, transport and install; and because components and parts of the open-close machine are arranged in a shell of the open-close machine, the open-close machine is easy to maintain,the equipment service life is prolonged, and the gate opening height is improved. The open-close machine provided by the invention concurrently has the operating characteristics of a winch open-closemachine, is wide in application range, and completely can replace an expensive winch open-close machine on medium and small sized gates which are opened and closed infrequently, therefore, the open-close machine can be used for remarkably saving the hydraulic investment.
Description
(1) Technical field [0001] The invention relates to a hoist for hydraulic gates, in particular to a vertical screw type hoist. (2) Background technology [0002] The screw type hoist currently in use, the lead screw or the screw is set vertically, and is divided into two working forms: nut rotation or lead screw rotation. Since the lead screw or the nut is directly connected with the gate, the two working forms are both There are the following disadvantages: the lead screw is too long, making it extremely inconvenient to manufacture, store, transport, install, and maintain, and the height of the door opening is limited. At the same time, the lead screw is easy to bend if it is not operated properly. Lead screw bending and lead screw and nut jamming are the main damage forms of traditional machines. (3) Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provides a vertical screw hoist which is convenient to manufa...
