Description

Technical Field

[0001] The utility model relates to the field of motor protection, in particular to a collision buffer mechanism and a motor emergency stop device. Background Art

[0002] In the existing equipment installed with linear motors, there is no effective anti-collision device for the protection of linear motors. Even if some equipment has a protective structure, they are just installed with an iron plate directly in front, which can only provide some superficial protection. Small collisions will not affect the operation of the motor equipment, but when a large collision occurs, a piece of iron plate alone cannot provide effective protection, and will only damage the iron plate and the equipment. Moreover, the equipment may continue to operate when a collision occurs. At this time, the collision is likely to physically damage the equipment motor and cause serious leakage and short-circuit hazards, resulting in more serious losses and higher risks of maintenance and repair.

[0003] Therefore, there is a need for a collision buffer mechanism and a motor emergency stop device that can play a more effective role in buffering and resisting shocks, and can automatically disconnect the motor operation when the impact is too large to reduce equipment losses to meet the needs of the existing environment. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] Since there is no effective anti-collision device for the existing protection of linear motors, even if some equipment has a protective structure, an iron plate is directly installed in the front, which has poor protection effect and is difficult to resist large impacts.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a protection assembly, comprising a housing, a protection arc plate rotatably arranged on one side of the housing, and a support plate installed on the inner wall of the housing;

[0007] The elastic component comprises a spring fixedly connected to the inner wall of the protective arc plate, an adjustment assembly fixedly connected to the other end of the spring, and a telescopic unit arranged inside the adjustment assembly.

[0008] As a preferred solution of the collision buffer mechanism of the utility model, wherein: a rotating shaft is fixedly provided on the side wall of the accommodating shell, a sleeve rod is fixedly provided on the inner wall of the protective arc plate, and the sleeve rod is rotatably connected to the rotating shaft.

[0009] As a preferred solution of the collision buffer mechanism of the utility model, the inner ring of the spring is provided with a positioning rod, the positioning rod slides along the inner wall of the adjustment assembly, and the positioning rod passes through the adjustment assembly and is located below the support plate.

[0010] As a preferred solution of the collision buffer mechanism of the utility model, a control hole is opened on the surface of the adjustment assembly, a transmission tube is rotatably sleeved on the inner wall of the control hole, and the other end of the transmission tube is fixedly connected to a rotating handle.

[0011] As a preferred solution of the collision buffer mechanism of the utility model, wherein: the inner wall of the transmission tube is provided with an oblique thread, a limit end is arranged in the transmission tube, a protrusion is fixedly arranged on the outer wall of the limit end, and the protrusion slides along the oblique thread.

[0012] As a preferred solution of the collision buffer mechanism of the utility model, wherein: an elastic telescopic rod is fixedly provided at the end of the limiting end head, and the other end of the elastic telescopic rod is fixedly connected to the rotating handle.

[0013] As a preferred solution of the collision buffer mechanism of the utility model, wherein: a limiting hole is fixedly provided on the surface of the positioning rod, and the limiting hole is in contact with the limiting end head.

[0014] The beneficial effects of the collision buffer mechanism in the utility model are: it can provide a better buffer function, can adapt to working environments of different sizes by adjusting the height of the positioning rod, and can achieve the effect of quick disassembly.

[0015] Given that the equipment may still be running when the existing collision occurs, the collision is likely to physically damage the equipment's motor and cause serious leakage and short-circuit hazards, resulting in more serious losses and higher risks for maintenance and repair.

[0016] In order to solve the above technical problems, the utility model also provides the following technical solutions: a power-off component, comprising a motor assembly arranged at the bottom of the accommodating shell and a matching switch electrically connected to the motor assembly.

[0017] As a preferred solution of the motor emergency stop device of the utility model, wherein: a support rod is fixedly arranged on the support plate, and a accommodating platform is installed on the top of the support rod.

[0018] As a preferred solution of the motor emergency stop device of the utility model, wherein: the matching switch is fixedly connected to the accommodating platform, a starting rod is provided on the top of the matching switch, and the other end of the starting rod is fixedly connected to the inner wall of the protective arc plate.

[0019] The beneficial effect of the motor emergency stop device in the utility model is that it can immediately associate with the switch when a large impact occurs, so that the motor and other equipment can be quickly shut down to ensure that no leakage short circuit hazards are caused, reducing losses and maintenance and repair risks.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the utility model is described in detail with reference to the schematic diagram. When describing the embodiments of the utility model, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the utility model. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1

[0030] Reference Figures 1-2 , which is the first embodiment of the utility model, and this embodiment provides a collision buffer mechanism.

[0031] The protection assembly 100 constitutes the external structure of the collision buffer mechanism. A protective arc plate 102 is provided on one side of the housing 101. The protective arc plate 102 covers the housing 101. The arc design is also convenient for maintenance and cleaning. A support plate 103 is also fixedly provided on the inner side of the housing 101. The support plate 103 divides the housing 101 into two layers, upper and lower.

[0032] The elastic component 200 is used to directly buffer and resist shock, and the inner wall of the arc protection plate 102 is fixedly connected with a spring 201. The surface of the support plate 103 is also fixedly provided with an adjustment assembly 202, and the other end of the spring 201 is fixedly connected to the top of the adjustment assembly 202. When an impact occurs, the spring 201 can play an effective buffering role.

[0033] The inner wall of the adjustment assembly 202 is also provided with a positioning rod 204 that can slide vertically. The positioning rod 204 is located in the inner circle of the spring 201. The positioning rod 204 itself can stabilize the spring 201 to prevent the spring 201 from bending and deforming under the impact of excessive external force. At the same time, the height of the positioning rod 204 is different, and the running distance of the protection arc plate 102 after being hit is also different. According to this situation, it can adapt to different sizes of working environments to cooperate with the power-off component 300. A telescopic unit 203 is provided inside the adjustment assembly 202. One end of the telescopic unit 203 can cooperate with the positioning rod 204, and the other end extends out of the adjustment assembly 202 and is located on the outer wall of the adjustment assembly 202 for easy manual adjustment.

[0034] The power-off assembly 300 is used to quickly power off the motor assembly 301 installed at the bottom of the housing 101 when the impact is too large. The matching switch 302 electrically connected to the motor assembly 301 is fixedly installed above the support plate 103, and the other end of the matching switch 302 is fixedly connected to the arc protection plate 102. When the arc protection plate 102 is hit hard, if the stabilizing spring 201 and the positioning rod 204 can support the movement of the arc protection plate 102, the motor assembly 301 is still safe. Otherwise, the arc protection plate 102 will move significantly until the matching switch 302 is turned on. The matching switch 302 will immediately power off the motor assembly 301 to ensure that there will be no leakage short circuit hazards, reducing losses and maintenance and repair risks.

[0035] Example 2

[0036] Reference Figures 1 to 3 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, but the difference is that the structure of the protective component 100 and the matching structure of the elastic component 200 are further optimized.

[0037] A rotating shaft 101a is fixedly arranged between the left and right side walls of the accommodating shell 101, and two sleeve rods 102a are also fixedly arranged on the inner wall of the protective arc plate 102. The two sleeve rods 102a are rotatably sleeved with the rotating shaft 101a respectively, and the protective arc plate 102 can also rotate around the rotating shaft 101a under the action of the sleeve rods 102a.

[0038] The inner wall of the adjustment assembly 202 is also provided with a positioning rod 204 that can slide vertically. The positioning rod 204 is located in the inner ring of the spring 201. The other end of the positioning rod 204 passes through the adjustment assembly 202 and is located below the support plate 103. Control holes 202a are fixedly opened on the surface of the adjustment assembly 202, and each control hole 202a corresponds to a positioning rod 204.

[0039] The inner wall of the control hole 202a is rotatably sleeved with a transmission tube 202a-1, and the other end of the transmission tube 202a-1 is fixedly provided with a rotating handle 202a-2, which is located on the outer wall of the adjustment assembly 202, so as to facilitate manual debugging by personnel, and the inner wall of the transmission tube 202a-1 is fixedly provided with an oblique thread 202a-3. A limit terminal 205 is arranged in the transmission tube 202a-1, and the front end of the limit terminal 205 faces the positioning rod 204 in the adjustment assembly 202, and an elastic telescopic rod 205b is fixedly arranged at the end of the limit terminal 205, and the other end of the elastic telescopic rod 205b is fixedly connected to the rotating handle 202a-2.

[0040] A protrusion 205a is fixedly provided on the outer wall of the limiting end 205, and the protrusion 205a and the oblique thread 202a-3 cooperate to slide. When the handle 202a-2 is turned to start driving the transmission tube 202a-1 to rotate in situ, the limiting end 205 can be driven to move horizontally under the elastic force of the elastic telescopic rod 205b under the cooperation of the protrusion 205a and the oblique thread 202a-3, so that the limiting end 205 and the limiting hole 204a fixedly provided on the surface of the positioning rod 204 are separated. At this time, the positioning rod 204 is no longer restricted by the limiting end 205 and can be raised and lowered manually. Moreover, the surface of the positioning rod 204 can be provided with a plurality of limiting holes 204a in the same row, which is convenient for adjusting the position of the positioning rod 204.

[0041] The height of the positioning rod 204 is different, and the running distance of the arc protection plate 102 after being hit is also different. According to this situation, it can adapt to working environments of different sizes to cooperate with the power-off component 300.

[0042] Example 3

[0043] Reference Figures 1 to 4 , which is the third embodiment of the utility model. This embodiment is based on the above embodiment and adds a motor emergency stop device.

[0044] The power-off assembly 300 is used to quickly power off the motor assembly 301 installed at the bottom of the housing 101 when the impact is too large. The motor assembly 301 is fixedly installed at the bottom of the housing 101. A support rod 303 is fixedly installed on the surface of the support plate 103, and an L-shaped accommodation platform 303a is fixedly installed on the top of the support rod 303 to assist in installing the matching switch 302.

[0045] The matching switch 302 is electrically connected to the motor assembly 301. A starting rod 302a is fixedly arranged on the top of the matching switch 302. The other end of the starting rod 302a is fixedly connected to the inner wall of the arc protection plate 102. When the arc protection plate 102 is subjected to a violent impact, the starting rod 302a will act on the matching switch 302. After the matching switch 302 starts to operate, the motor assembly 301 will be immediately powered off. This ensures that the motor assembly 301 will not cause leakage and short circuit hazards under a violent impact, and also reduces losses and maintenance and repair risks.
