Technical Field

[0001] This utility model relates to the field of gate hoisting technology, specifically a single-drive double-lifting-point gate hoisting machine. Background Technology

[0002] A gate hoist is a device used to control and drive the opening and closing movements of valves, gates, doors, and windows. A gate hoist typically consists of a motor, a reducer, a drive shaft, and a control system. The motor drives the drive shaft to rotate, thereby achieving the opening and closing action of the valve or gate. Gate hoists are widely used in industrial production, automating the opening and closing operations of equipment and improving production efficiency and safety.

[0003] Currently, gate hoists are typically controlled by a dual-motor drive. However, the synchronization of dual-motor drives is insufficient, and after the gate hoist winds up, brake pads are needed to lock the drum. In rainy weather, the brake pads can slip due to water, causing the gate hoist to malfunction. Therefore, improvements are needed. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model designs a meshing mechanism between bevel gear one and bevel gear two. When the drive motor is working, it can realize the rotation of the connecting shaft and the drum to wind up and unwind the gate. Driven by one motor, both drums can rotate simultaneously, resulting in better synchronization. The rotation of the connecting shaft can drive the top block to rotate and squeeze the protrusion, which in turn can cause the top plate to squeeze the sponge block. This allows the lubricating oil inside the sponge block to be squeezed into the drain pipe. The lubricating oil can then lubricate the bevel gear, reducing friction and extending service life.

[0014] 2. This utility model utilizes the design of a rotating motor. The output end of the rotating motor can drive the screw to rotate, which can realize the threaded movement of the connecting block. The connecting block can drive the insert block to move, allowing the insert block to be inserted into the slot of the rotating seat. At this time, the rotating seat can be limited, thus limiting the drum and preventing the gate from moving when the machine stops. Attached Figure Description

By designing the spring 83, the force of the spring 83 can act on the top plate 84. The lower end of the sponge block 82 contacts the top plate 84. A sealing sleeve 85 is fixedly sleeved on the outside of the top plate 84. The sealing sleeve 85 contacts the sponge block 82 and is slidably connected to the fixed seat 1.

[0023] Please see Figure 1 , Figure 2 , Figure 4 The locking mechanism 9 includes a slot 91. The rotating seat 7 has a slot 91 inside. A plug 92 is slidably connected inside the slot 91. There are multiple slots 91, which are evenly distributed inside the rotating seat 7. By designing multiple slots 91, the plug 92 can be inserted into slots 91 at different positions.

[0026] When it is necessary to limit the winding drum 10, the rotating motor 96 is started. The output end of the rotating motor 96 drives the screw 97 to rotate, causing the connecting block 93 to make threaded movement. The connecting block 93 drives the guide block 94 to slide along the guide groove 95. At the same time, the connecting block 93 drives the insert block 92 to move down, so that the insert block 92 is inserted into the slot 91 in the rotating seat 7.
