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. The horizontal 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 screw is driven to rotate by the transmission part. One-body screw 2, that is, two coaxial shafts connected to each other and the thread direction is opposite to the screw. Seat 18 is positioned, is provided with mechanical device on two nuts 5, links to each other with gate by the mechanical facility that cooperates with it and connector. The transmission and speed change parts established on the Siamese leading screw 2 feed rods is a worm gear reducer 3, and the worm gear is vertically arranged, and the Siamese leading screw 2 fixedly connected with it is positioned in the thrust bearing 4 that the worm wheel both sides in the housing are provided with. The mechanical device arranged on the nut 5 is a symmetrically arranged movable pull...

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...
