Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric hoists, in particular to a high-precision anti-deflection electric hoist hook. Background Art
[0002] Electric hoist is a kind of lifting equipment installed on overhead crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and easy use. It is used in industrial and mining enterprises, warehouses, docks and other places.
[0003] Existing wire rope electric hoist hooks are usually lightweight to save costs, which causes the hook head to be skewed when the hook is empty. When the hoisted object is heavy, the hook itself cannot maintain balance and is prone to swinging. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a high-precision anti-skew electric hoist hook. By arranging the counterweight shell, the upper counterweight shaft and the lower counterweight shaft, the hook head is positioned on the counterweight shell, the lower counterweight shaft and the upper counterweight shaft, so that the gravity of the hook head itself is guaranteed, so that the hook will not be skewed when it is hung in the air, thereby ensuring the lifting stability of the hook, and can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-precision anti-skew electric hoist hook, comprising a hook, a fixed cover is provided at the upper end of the hook, a lower counterweight shaft is horizontally passed through the upper end of the hook, a counterweight shell is provided at both ends and sides of the lower counterweight shaft, two pulleys are installed on the upper part of the lower counterweight shaft, an upper counterweight shaft is passed through the center of the pulley, and four-axis gyroscopes are installed at the four corners of the upper part of the counterweight shell.
[0006] Furthermore, a partition plate is provided on the upper side of the fixed cover, and the partition plate is welded to the counterweight shell.
[0007] Furthermore, an inspection cover is provided on the outside of the counterweight housing corresponding to the position of the pulley, and the inspection cover is connected to the counterweight housing by bolts.
[0008] Furthermore, the four-axis gyroscope is connected to the counterweight housing via bolts, and the pulley is connected to the upper counterweight shaft via bearings.
[0009] Furthermore, the fixing cover is connected to the upper end of the hook via bolts, and the upper part of the hook is plugged into the lower counterweight shaft.
[0010] Furthermore, a covering plate is provided on the upper side of the pulley.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The utility model arranges the counterweight shell, the upper counterweight shaft and the lower counterweight shaft so that the hook head is located on the counterweight shell, the lower counterweight shaft and the upper counterweight shaft, so that the gravity of the hook head is guaranteed, and the hook will not be skewed when it is hoisted in the air, thereby ensuring the lifting stability of the hook.
[0013] 2. The utility model is equipped with a four-axis gyroscope, so that when the hook is lifting objects, the four-axis gyroscope can automatically detect the tilt angle and position of the hook, and then the electric hoist adjusts the tilt position of the hook through the wire rope, so that the hook remains balanced and avoids swinging.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-2 This embodiment provides a technical solution: a high-precision anti-skew electric hoist hook, including a hook 1, a fixed cover 9 is provided on the upper end of the hook 1, a lower counterweight shaft 2 is horizontally passed through the upper end of the hook 1, and a counterweight shell 4 is provided at both ends and sides of the lower counterweight shaft 2. Two pulleys 5 are installed on the upper part of the lower counterweight shaft 2, an upper counterweight shaft 7 is passed through the center of the pulley 5, and a four-axis gyroscope 3 is installed at the four corners of the upper part of the counterweight shell 4.
[0019] like Figure 1-2 As shown, when the hook is in use, the wire rope passes through the pulley 5. Under the action of the power equipment, the wire rope can adjust the hook 1 up and down. The counterweight housing 4, the lower counterweight shaft 2 and the upper counterweight shaft 7 make the overall weight of the hook 1 heavier, so that the stability of the hook 1 is guaranteed, and the hook 1 is prevented from tilting when it is empty. When lifting objects, the four-axis gyroscope 3 can accurately measure the inclination and position of the hook 1 structure, so that the electric hoist can adjust the inclination and position of the hook 1 through the wire rope, so that the hook 1 remains balanced and avoids swinging.
[0020] A partition plate 8 is provided on the upper side of the fixed cover 9 , and the partition plate 8 is welded to the counterweight shell 4 .
[0021] An inspection cover 6 is provided on the outside of the counterweight housing 4 at a position corresponding to the pulley 5 , and the inspection cover 6 is connected to the counterweight housing 4 by bolts.
[0022] The four-axis gyroscope 3 is connected to the counterweight housing 4 through bolts, and the pulley 5 is connected to the upper counterweight shaft 7 through bearings.
[0023] The fixing cover 9 is connected to the upper end of the hook 1 by bolts, and the upper part of the hook 1 is plugged into the lower counterweight shaft 2.
[0024] A cover plate is provided on the upper side of the pulley 5 .
[0025] The working principle of a high-precision anti-skew electric hoist hook provided by the utility model is as follows: Figure 1-Figure 2 As shown, when the hook is in use, the wire rope passes through the pulley 5. Under the action of the power equipment, the wire rope can adjust the hook 1 up and down. The counterweight housing 4, the lower counterweight shaft 2 and the upper counterweight shaft 7 make the overall weight of the hook 1 heavier, so that the stability of the hook 1 is guaranteed, and the hook 1 is prevented from tilting when it is empty. When lifting objects, the four-axis gyroscope 3 can accurately measure the inclination and position of the hook 1 structure, so that the electric hoist can adjust the inclination and position of the hook 1 through the wire rope, so that the hook 1 remains balanced and avoids swinging.
