Description

Technical Field

[0001] This utility model relates to the field of belt breakage detection technology, and in particular to a belt breakage detection mechanism and lifting device. Background Technology

[0002] In automated production lines, lifting devices use motors to drive a winding reel, which in turn winds and unwinds the transmission belt on the reel, thus achieving the lifting function. When the object being lifted is too large or the transmission belt is severely worn, belt breakage may occur. This needs to be detected immediately so that the machine can be stopped for maintenance. Therefore, a belt breakage detection mechanism is designed to address this issue. Utility Model Content

When the transmission belt of the external mechanism is intact, the pressure roller will be blocked by the transmission belt and will not move downward. The detection module will not detect the pressure roller and will judge that the belt is intact.

[0022] 2. The overall structure is simple and the manufacturing cost is low.

[0023] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0025] Figure 2 This is a three-dimensional structural diagram of a belt breakage detection mechanism for detecting a transmission belt according to an embodiment of the present invention.

[0026] Figure 3 This is a three-dimensional structural diagram of a lifting device according to an embodiment of the present utility model. Detailed Implementation

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0028] First, combine Figures 1-2 This invention describes a belt breakage detection mechanism according to an embodiment of the present invention, used for detecting belt breakage of a transmission belt 700, and has a wide range of applications.

[0029] like Figures 1-2 As shown, a belt breakage detection mechanism according to an embodiment of the present invention includes a base 100, a pair of support frames 200, a pressure module, a pressure roller 400, and a detection module.

[0030] Specifically, such as Figures 1-2As shown, a pair of support frames 200 are arranged on the top sides of the base 100.

[0031] Specifically, such as Figures 1-2 As shown, a pressure-applying module is mounted on a pair of support frames 200 and is used to apply downward pressure. The pressure-applying module includes: a pair of elongated grooves 301, a pair of guide rods 302, and a pair of elastic elements 303. The pair of elongated grooves 301 are respectively formed on the pair of support frames 200, and the two ends of the pressure roller 400 are respectively guided and positioned within the pair of elongated grooves 301; the bottom ends of the pair of guide rods 302 are respectively connected to the two ends of the pressure roller 400, and the top ends of the pair of guide rods 302 respectively penetrate the pair of support frames 200; the pair of elastic elements 303 are respectively sleeved on the pair of guide rods 302, and the elastic elements 303 are located between one end of the corresponding pressure roller 400 and the top end of the elongated groove 301, and the elastic elements 303 are springs. The elastic force of the elastic elements 303 applies pressure to the pressure roller 400.

[0032] Furthermore, such as Figures 1-2 As shown, the pressure module also includes: a pair of limit caps 304, which are respectively disposed at the top of a pair of guide rods 302 to limit the stroke of the guide rods 302.

[0033] Specifically, such as Figures 1-2 As shown, the detection module is located on the outside of the base 100. When the transmission belt 700 of the external mechanism is intact, the pressure roller 400 is blocked by the transmission belt 700 and does not move downwards. The detection module cannot detect the pressure roller 400 and determines that the belt is intact. When the transmission belt 700 of the external mechanism breaks, the pressure module drives the pressure roller 400 to move downwards, which is detected by the detection module and determined to be a broken belt. The detection module includes a mounting bracket 501 and a proximity switch 502. The mounting bracket 501 is located on one side of the base 100; the proximity switch is located on the mounting bracket 501.

[0034] Furthermore, such as Figures 1-2 As shown, a belt breakage detection mechanism according to an embodiment of the present invention further includes: a pair of guide rollers 600, which are disposed on both sides of the base 100 for guiding and limiting the transmission belt 700.

[0035] Initially, the pressure roller 400 presses on the transmission belt 700 of the external mechanism. At this time, a pair of elastic elements 303 will be compressed. When the belt breaks, the pair of elastic elements 303 will no longer be compressed. The pressure roller 400 will move downward under the action of the pair of elastic elements 303, which will be detected by the proximity switch 502, which will determine that the belt is broken and send out a belt break signal.

[0036] As described above, the tape breakage detection mechanism according to an embodiment of the present invention has the following beneficial effects:

[0037] 1. It can trigger a response the moment the transmission belt breaks at 700°, sending a belt break signal to prompt workers to carry out repairs;

[0038] 2. The overall structure is simple and the manufacturing cost is low.

[0039] The above combined with the appendix Figures 1-2 A belt breakage detection mechanism according to an embodiment of the present invention is described. Furthermore, the present invention can also be applied to a lifting device.

[0040] like Figure 3 As shown, according to a second aspect of the present invention, a lifting device is provided, comprising a belt breakage detection mechanism 1 as described in the first aspect.

[0041] It should be noted that, in this specification, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0042] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above content. Therefore, the scope of protection of the present invention should be defined by the appended claims.
