Description

Technical Field

[0001] This utility model belongs to the technical field of gate equipment, and in particular relates to a winch-type gate opening and closing machine drum. Background Technology

[0002] Winch-type gate hoists are mainly used for opening and closing planar gates or arc gates. They rely on the gate's own weight, water column, or other weighting methods to close the orifice gate. Usually, one hoist is used for one gate. They can be operated individually or centrally, as well as locally or remotely. They are widely used for opening and closing gates in various parts of water discharge, diversion, and inlet.

[0003] Gate hoists are classified by the number of lifting points into single-point and double-point types; and by the drum winding method into single-layer and multi-layer winding types. Scientifically selecting the hoisting mechanism's transmission method not only reduces the overall structural size, facilitating hydraulic engineering layout, but also lowers the hoist's weight and cost. The traditional reducer + open gear transmission scheme reduces the torque requirements of the reducer; the current mainstream design concept is to adopt an ultra-large, fully enclosed transmission arrangement. The drum used in the winch adopts an all-metal structure, cast by pouring and reinforced with welded parts, resulting in a stable structure. However, the high-torque gears used in the transmission bear enormous torque due to the weight of the gate, and ordinary castings are difficult to meet the requirements, easily leading to wear and deformation. Utility Model Content

[0004] The purpose of this utility model is to provide a winch-type gate hoist drum. Existing cast drum end-side gears have a large torque, which solves the problem of deformation and easy damage caused by insufficient strength of the gear teeth.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A winch-type gate hoist drum includes a cylindrical body with a spiral rope groove on its circumference. A rotating shaft is coaxially fixed to the cylinder, and a rotating roller is installed at the end of the rotating shaft.

[0007] A turntable is fixed to one end of the cylinder. The turntable is a circular structure. A gear ring is fitted onto the turntable. The outer ring of the gear ring has teeth, and a gear ring is fixed to the inner ring. The gear ring is integrally fixed to the side of the gear ring. The gear ring overlaps with the side of the turntable, and through holes are provided in the corresponding overlapping parts for fixing with bolts.

[0008] Furthermore, a reinforcing ring is fixed on the overlapping side of the turntable, and a reinforcing ridge is formed on the outer ring side of the reinforcing ring. Multiple reinforcing ridges are evenly arranged around the reinforcing ring, and the gear ring has a groove to accommodate the reinforcing ridges for limiting installation.

[0009] Furthermore, multiple fixing discs are fixed between the rotating shaft and the inner wall of the cylinder. The fixing discs are circular in structure and arranged at intervals. Each fixing disc has a weight reduction hole.

[0010] A first rib is also fixed between the fixed plate and the rotating shaft on the corresponding end side of the cylinder. The turntable and the cylinder are separate structures. A second rib is provided between the turntable and the fixed plate on the corresponding end side of the cylinder. The second rib is corresponding to the first rib. A fixing member is installed at the end of the rope groove of the cylinder to fix the end rope.

[0011] The present invention has the following advantages: the cylindrical part corresponding to the drum is prepared by casting, while the gear ring of the stress part is detachably installed with the drum. After the gear ring is cast, it will undergo secondary processing, and its industrial properties will be increased by quenching and other technologies, thereby greatly reducing the additional costs caused by the overall processing.

[0018] The components represented by each number in the attached diagram are listed below: cylinder 1, shaft 3, roller 31, motor 5, gearbox 51, small diameter gear 52, gear ring 2, turntable 11, gear ring 21, through hole 22, bolt 4, reinforcing ring 12, reinforcing rib 13, rib groove 23, fixing plate 32, weight reduction hole 33, first plate rib 6, second plate rib 7, and fastener 8. Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1-3 As shown: A winch-type gate hoist drum includes a cylindrical drum 1 with a spiral rope groove on the circumference of the drum 1. A rotating shaft 3 is coaxially fixed to the drum 1, and a rotating roller 31 is installed at each end of the rotating shaft 3.

[0021] This drum-type equipment is used in gate hoists to wind and lift steel cables for gates. The overall hoist also includes a support frame, on which a motor 5 is mounted. The output end of the motor 5 is a gearbox 51, and the output gear of the gearbox 51 is a small-diameter gear 52. A large-diameter gear ring 2 is located on the end of the drum 1. This increases torque during transmission, enabling the lifting of steel gates weighing tons. To further reduce motor power, a movable pulley system is installed at the lower end of the rope, balancing the force and improving stability. Therefore, rope grooves are symmetrically arranged on both sides of the drum.

[0022] A turntable 11 is fixed to one end of the cylinder 1. The turntable 11 is a disc structure. A gear ring 2 is fitted onto the turntable 11. The outer ring of the gear ring 2 has gear teeth, and a gear ring 21 is fixed to the inner ring. The gear ring 21 is integrally fixed to the side of the gear ring 2. The gear ring 21 overlaps with the side of the turntable 11, and through holes 22 are provided in the corresponding overlapping parts for fixing with bolts 4.

[0023] Because large gears for transmission need to be installed on the ends of the cylinder, and the meshing of these gears bears enormous torque, ordinary drums are cast using a casting method. However, the lack of quenching and other processes in the overall metal material manufacturing process results in gear rings with either too low or too high hardness, both of which can lead to gear tooth deformation or wear during operation. Furthermore, performing secondary processing on the cast cylinder to improve its impact resistance would significantly increase manufacturing costs.

[0024] Therefore, the cylinder body of this roll is prepared by casting, while the gear ring of the load-bearing part is detachably installed from the cylinder body. After the gear ring is cast, it will undergo secondary processing, and its industrial properties will be increased through technologies such as quenching, thereby greatly reducing the additional costs caused by the overall processing.

[0025] like Figure 1 As shown: A reinforcing ring 12 is fixed to the overlapping side of the turntable 11. A reinforcing rib 13 is formed on the outer ring side of the reinforcing ring 12. Multiple reinforcing ribs 13 are evenly distributed around the reinforcing ring 12. The gear ring 21 has a groove 23 to accommodate the reinforcing ribs 13, providing a limiting installation. When the gear ring and turntable are overlapped, the reinforcing ribs are limited and installed in the groove, improving the transmission properties between the turntable and the gear ring and preventing excessive torque from causing bolt deformation. Specifically, there are 8-12 reinforcing ribs, with corresponding bolts installed at intervals on adjacent reinforcing ribs.

[0026] like Figure 5As shown: Multiple fixed discs 32 are fixed between the rotating shaft 3 and the inner wall of the cylinder 1. The fixed discs 32 are circular in structure and arranged at intervals. Each fixed disc 32 has a weight-reducing hole 33. These holes are used for synchronous rotation of the rotating shaft and the cylinder. The joints between the fixed discs and the rotating shaft and the cylinder are welded together. There are four circular weight-reducing holes, evenly distributed. A first rib 6 is also fixed between the fixed disc 32 and the rotating shaft 3 on the corresponding end of the cylinder 1. The first rib and the weight-reducing holes are spaced apart to improve the rotational stability of the corresponding end position of the rotating shaft.

[0027] The turntable 11 and the cylinder 1 are separate structures. A second rib 7 is provided between the corresponding end fixing plates 32 of the turntable 11 and the cylinder 1. The second rib 7 is corresponding to the first rib 6. A fixing member 8 is installed at the end of the rope groove of the cylinder 1 to fix the end of the rope. The separate design of the cylinder structure facilitates the installation of fixing members at the end positions. The fixing member is a block structure with a screw hole in the center for fixing with screws. The inner side of the fixing member has a groove for fixing the steel cable. In order to reduce the rotational pressure of the shaft, a second rib is provided between the turntable and the corresponding end fixing plates of the cylinder to increase the transmission function.

[0028] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
