Example Embodiment

[0014] The drawings show a specific embodiment of the invention. The horizontal screw hoist is mainly composed of a power machine, a transmission transmission system, a lead screw, a nut, a base and a hand crank. The lead screw is driven to rotate by a transmission part, and is characterized in that the lead screw is set horizontally, which is a continuous Body screw 2, that is, a screw with two coaxial wires connected with opposite threads. The middle part of the two threads of the conjoined screw 2 is a light rod. The light rod is equipped with a transmission transmission component connected with the main transmission transmission system and is on the machine. The seat 18 is positioned, and a mechanical device is provided on the two nuts 5, which is connected to the gate through the mechanical facilities and connecting pieces that are matched with it. The transmission and transmission component of the conjoined screw 2 on the smooth rod is a worm gear reducer 3. The worm gear...

Abstract

The invention discloses a headstock gear for a hydraulic gate, in particular a horizontal screw type headstock gear mainly comprising a power machine, a driving speed change system, a screw rod, two nuts, a machine seat and a hand crank, wherein the screw rod is driven to rotate by a driving part. The horizontal screw type headstock gear is characterized in that the screw rod is horizontally arranged and is a siamesed screw rod including two screw rods which are coaxially connected and have opposite thread rotating directions; a feeding rod is arranged between two threads of the siamesed screw rod and is provided with a driving speed change part which is connected with the main driving speed change system and is positioned on the machine seat; and mechanical devices are arranged on the two nuts and are connected with the gate by a mechanical facility and a connecting piece which are matched with the mechanical devices. The horizontal screw type headstock gear solves the problem that the screw rods are overlong, is convenient for manufacture, storage, transportation, installation and maintenance, prolongs the running service of the equipment, improves the door-opening height, can completely replace the winch hoist with expensive price on medium and small hydraulic gates in the infrequent start and close processes and can greatly save the engineering investment.

Description

(1) Technical field [0001] The invention relates to a hoist for hydraulic gates, in particular to a horizontal 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 horizontal screw hoist with convenient manufactu...
