Problems solved by technology

[0004] The above existing technical solutions have the following defects: during the operation of the electric hoist, the electrical components in the control box will generate a large amount of heat, and the control box on the electric hoist working in an environment with a lot of dust often needs to be sealed Set to prevent dust from entering the control box, which will cause the heat generated by the electrical components to not dissipate from the control box in time, and the electrical components are easily damaged in high temperature environments

Embodiment 1

[0037] refer to figure 1, is an electric hoist that is convenient for heat dissipation disclosed in the present invention, including an electric trolley 1 slidingly connected on the guide rail, a hoist body 3 suspended below the electric trolley 1, and a control box 2 installed on the electric trolley 1, and the hoist body 3 It includes a sprocket 33 , a second reducer 32 installed on one side of the sprocket 33 and a second motor 31 . The second motor 31 controls the rotation of the sprocket 33 through the second speed reducer 32, and the sprocket 33 is wound with a chain ring 5, and the suspension hook 4 is installed on the chain ring 5. Electrical components for controlling the operation of the second motor 31 are installed in the control box 2 , and the electrical components are connected to the second motor 31 through cables.

[0038] see figure 1 , figure 2 , the electric car 1 includes a first mounting plate 11, a second mounting plate 12, a drive mechanism 15, ther...

Embodiment 2

[0047] see Image 6 The difference from Embodiment 1 is that the gourd body includes a ball-worm gear mechanism and a second motor. The ball-worm gear mechanism is a transmission structure disclosed in a Chinese invention patent with the publication number CN102338195A. The ball-worm gear mechanism includes The worm, the ball worm gear, the ball worm gear and the worm mesh with each other, the worm is coaxially fixed with the output shaft of the second motor, and the worm gear is coaxially connected with the sprocket.

Abstract

The invention relates to an electric hoist for heat dissipation, comprising an electric trolley, a hoist body, a control box and a water cooling device, wherein electrical components are installed in the control box, and the water cooling device includes a water storage tank, a first water pump and Two water-cooled pipes, cooling water is stored in the water storage tank, and the two water-cooled pipes are respectively connected to the two ends of the first water pump, part of the water-cooled pipes are located in the control box, and some of the water-cooled pipes are located outside the control box. There are several through holes for the passage of water-cooling pipes, each of which is equipped with a sealing ring, and the electric trolley is provided with a driving mechanism for driving the first water pump. When the hoist body is working, the electrical components in the control box work and generate heat, and the driving mechanism drives the first water pump to run, so that the cooling water in the water-cooling tube is driven and circulates continuously in the water-cooling tube, and the flowing cooling water can continuously Help the control box to dissipate heat, so that the temperature rise rate in the control box can be controlled.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to an electric hoist that facilitates heat dissipation. Background technique [0002] Electric hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage, docks and other places. [0003] At present, the Chinese patent with the notification number CN108657951A discloses an electric hoist structure for lifting equipment, including: the electric hoist body, on which the hook structure is set, connected to the electric trolley through the hook, and connected to the upper end of the electric trolley The I-beam is used, and a conical rotor motor is installed in the electric hoist body. The conical rotor motor is connected to the reducer through the main shaft, and the sprocket ...
