Description

Technical Field

[0001] This utility model relates to the field of gate hoisting technology, specifically to a gate hoisting machine for water conservancy projects. Background Technology

[0002] Gate hoists are used to control the lifting and lowering of various large and medium-sized cast iron gates and steel gates. However, the gate hoists currently in use have simple structures and mostly use a single transmission method, which cannot achieve the switching between manual and electric operation, seriously affecting the practicality of the gate hoists.

[0003] The specification of a hydraulic engineering gate hoist in the prior art (announcement number CN221118428U) mentions that "a support column is fixed to the top corner of the base by screws, and a housing is fixed to the top of the support column by screws. The housing is provided with a drive motor, a slide, a through hole, a drive shaft sleeve and a bracket. The drive motor is fixed to the left rear end of the housing by screws. The slide is opened on the left side of the rear end of the housing. The through hole is symmetrically opened in the middle of the top and bottom of the housing. The drive shaft sleeve is connected to the middle of the inside of the housing by an interference fit bearing. The bracket is symmetrically fixed to the rear end of the inside of the housing by screws." However, the operating turntable in the prior art may malfunction or be misoperated, affecting the safety and stability of operation. Moreover, the upper part of the screw may bend due to excessive tension during rotation, which is not safe, stable and durable. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a gate hoist for hydraulic engineering is provided to solve the problems in existing technologies, such as the possibility of the operating turntable malfunctioning or being misoperated, affecting the safety and stability of operation, and the possibility of the upper part of the screw bending due to excessive tension during rotation, which makes it unsafe, unstable and not durable.

[0005] To achieve the above objectives, a gate hoist for hydraulic engineering is provided, comprising a casing, side mounting brackets, and a right anti-bend sleeve structure. Side mounting brackets are fixed to both the left and right sides of the casing, and a telescopic cylinder is installed at the upper end of each side mounting bracket. A top plate is installed at the upper end of each telescopic cylinder, and a double-fork slot on the upper side of the top plate engages with a set of connecting rods at the upper end of the casing. An oil tank is fixed to the center of the front side of the casing, and conveying pipes are installed on both the left and right sides of the lower end face of the oil tank. The lower end of each conveying pipe leads to the inner wall of the upper protective sleeve at the lower part of the casing, and a screw is fitted inside the upper protective sleeve. A left anti-bend sleeve structure is fitted over the left side of the screw, and a right anti-bend sleeve structure is fitted over the right side of the screw.

[0006] Furthermore, an upper connecting shaft is installed at the center of the chassis, and four sets of middle connecting rods are fixed at the upper end of the upper connecting shaft, with the outer ends of the middle connecting rods fixed on the inner ring surface of the upper turntable.

[0007] Furthermore, a turbine is installed in the center of the casing, the lower end of the upper connecting shaft is fixed inside the turbine, and a drive motor is installed on the rear right side of the casing. The front part of the worm gear installed at the front end of the drive motor is connected to the turbine for transmission.

[0008] Furthermore, the inner bottom surface of the double-fork slot is provided with an anti-slip plate, and the anti-slip plate is made of silicone rubber.

[0009] Furthermore, the upper end face of the oil tank is provided with an inlet, and the upper part of the delivery pipe provided on the lower end face of the oil tank is equipped with an electromagnetic control valve. The delivery pipe is connected to the interior of the upper protective sleeve, and a support frame is provided outside the upper protective sleeve.

[0010] Furthermore, a side fixing block is fixed in the middle of the right anti-bending sleeve structure, and a side fixing frame is fixed on the outside of the side fixing block. The upper end of the side fixing frame is fixed to the base. The right anti-bending sleeve structure is made of cast steel, and the left and right anti-bending sleeve structures are symmetrical about the center line of the screw. The left and right anti-bending sleeve structures have the same structural configuration.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model extends upwards via telescopic cylinders on the left and right sides of the chassis, and the top plate presses against the lower end of the middle connecting rod, securing the two sets of double-fork slots on the top plate to the front and rear sides of the middle connecting rod. This ensures that the upper turntable remains stable when not in use, preventing malfunctions or misoperation by unauthorized personnel, making it safer, more stable, and reliable.

[0012] 2. In this utility model, the oil is delivered to the upper protective sleeve through two sets of conveying pipes at the bottom of the oil tank. The upper part of the screw extends into the upper protective sleeve and is fixed to the lower end of the upper connecting shaft, so that the lubricating oil can be gradually lubricated to the screw, thereby reducing wear on the screw during rotation and preventing jamming.

[0013] 3. The left and right anti-bending sleeve structures in this utility model are designed to prevent the screw from bending due to excessive height of the upper rod during rotation. By placing the left and right anti-bending sleeve structures on the left and right sides of the outer ring surface of the screw, they help to stably and straighten the screw, ensuring that the rod remains straight during rotation, resulting in safer and longer operation.
