Description

Technical Field

[0001] The utility model relates to the technical field of wire transmission devices, in particular to a novel lifting wire transmission device. Background Art

[0002] The lifting line is a wire that can be raised and lowered. It can be used in various scenarios such as life and production. For example, in the production process of workpieces, the lifting line is first lowered, then the lifting line is further tied to the workpiece, and finally the lifting line is raised to achieve the purpose of hanging and drying the workpiece.

[0003] Among them, there is an existing lifting wire transmission device including a box, a motor, a wire reel and other components. The motor and the wire reel are both arranged inside the box. The motor is connected to the wire reel. A lifting wire is wound around the wire reel. A lifting wire through-hole is provided at the bottom of the box. When working, the wire reel is driven to rotate by the motor, so that the lifting wire passes through the lifting wire through-hole in and out of the box to realize the rising and falling of the wire.

[0004] However, the above-mentioned lifting line transmission device has the following technical problems: when the lifting line is running without load (for example, during the descent of the lifting line without any objects tied to it), and the motor is still in working condition, the lifting line is prone to become loose, and the lifting line is difficult to lead out from the inside of the box, which can easily lead to problems such as the lifting line getting stuck in the wire drum, thereby affecting the normal transmission of the lifting line.

DETAILED DESCRIPTION

[0024] 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.

[0025] The utility model provides a new type of lifting wire transmission device, including a box body 1, a first motor 2 and a wire drum 3. The first motor 2 and the wire drum 3 are both arranged inside the box body 1. The first motor 2 is connected to the wire drum 3 to drive the wire drum 3 to rotate. A lifting wire 4 is wound around the wire drum 3, and a lifting wire through hole 5 is provided at the bottom of the box body 1.

[0026] In addition, the new lifting line transmission device also includes a second motor 6, a third motor 7, a first conduction wheel 8 and a second conduction wheel 9. The second motor 6 and the third motor 7 are both arranged inside the box 1, the second motor 6 is connected to the first conduction wheel 8, and the third motor 7 is connected to the second conduction wheel 9. The first conduction wheel 8 and the second conduction wheel 9 are spaced apart from each other to form a conduction wheel gap. The first conduction wheel 8 and the second conduction wheel 9 are both located at the bottom of the wire drum 3 and between the lifting line through hole 5. The conduction wheel gap corresponds to the lifting line through hole 5 in the upper and lower parts. The lifting line 4 passes through the conduction wheel gap. The first conduction wheel 8 contacts one side of the lifting line 4 and the second conduction wheel 9 contacts the other side of the lifting line 4.

[0027] It can be understood that the descending transmission process of the lifting line 4 of the present invention is as follows: the first motor 2 drives the wire drum 3 to rotate; the lifting line 4 on the wire drum 3 passes through the gap between the conduction wheels, the second motor 6 drives the first conduction wheel 8 to rotate and the third motor 7 drives the second conduction wheel 9 to rotate, and the lifting line 4 is transmitted downward through the first conduction wheel 8 and the second conduction wheel 9 to be transmitted toward the lifting line through hole 5, that is, the rotating first conduction wheel 8 and the second conduction wheel 9 provide a force to both sides of the lifting line 4 to better avoid the lifting line 4 from being in a slack state when there is no load; finally, the lifting line 4 transmitted by the first conduction wheel 8 and the second conduction wheel 9 passes through the lifting line through hole 5, so that the lifting line 4 is led out from the inside of the box body 1, thereby realizing the descending transmission of the lifting line 4.

[0028] In this embodiment, the first conduction wheel 8 and the second conduction wheel 9 are arranged one above the other, that is, they are not on the same horizontal line. In other embodiments, the first conduction wheel 8 and the second conduction wheel 9 may also be on the same horizontal line. This is not particularly limited here.

[0029] Preferably, a support plate 10 is provided inside the box 1, and the wire drum 3 is mounted on the support plate 10 via a rotating shaft. The first motor 2 is mounted on the support plate 10 and is located below the wire drum 3. Furthermore, the first motor 2 is provided with a first synchronous wheel 11, and the rotating shaft is provided with a second synchronous wheel. The first synchronous wheel 11 is connected to the second synchronous wheel via a synchronous belt. During operation, the first motor 2 drives the first synchronous wheel 11 to rotate, and further drives the second synchronous wheel to rotate via the synchronous belt, thereby realizing the rotation of the rotating shaft and the wire drum 3.

[0030] In addition, the support plate 10 can be connected to a first bracket 12, which is connected to a second bracket 13. The third motor 7 is disposed on the first bracket 12, and the second motor 6 is disposed on the second bracket 13. Of course, the second motor 6 and the third motor 7 can also be fixedly disposed inside the box body 1 using other structural members, and no further restrictions are imposed here.

[0031] Specifically, the present invention further includes a power supply disposed inside the box 1 , through which power is supplied to the first motor 2 , the second motor 6 , and the third motor 7 .

[0032] In addition, preferably, a hanging ring 14 and a mounting bracket 15 are provided on the top of the box body 1 to facilitate the installation and fixation of the box body 1 of the present invention.

[0033] Compared with the prior art, the present invention provides a new lifting line transmission device with the following beneficial effects: the present invention is provided with a first conduction wheel and a second conduction wheel between the bottom of the line drum and the lifting line through hole. When the lifting line is running without load, the first motor is still in working state, and the second motor and the third motor are also working at the same time. The second motor drives the first conduction wheel to rotate and the third motor drives the second conduction wheel to rotate, so that the lifting line is transmitted through the first conduction wheel and the second conduction wheel, which better avoids the lifting line from being in a loose state and better allows the lifting line to be led out from the inside of the box, thereby better solving the problem of the lifting line getting stuck in the line drum and ensuring the normal transmission of the lifting line.

[0034] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
