Description

Technical Field

[0001] The utility model belongs to the technical field of rotation monitoring equipment, and in particular relates to a novel rotation monitoring device capable of preventing mechanical accidental collision. Background Art

[0002] Power plants often use proximity switches to monitor the operating status of equipment. They are widely used due to their small size and simple wiring. The existing rotation monitoring device probe is vertically installed in front of the turntable, and the turntable is fixed on the shaft. When the turntable rotates, the rotation monitoring device probe senses the turntable and lights up. When it senses holes on the turntable surface, the light goes out. Therefore, the rotation of the turntable is monitored by the flashing of the rotation monitoring device light.

[0003] During operation, the turntable may shake due to the movement of the rotating shaft, causing the distance between the turntable and the probe to change. The monitoring device may be far away from the turntable at different times, which may easily damage the probe of the monitoring device and the equipment. When the turntable is disassembled and replaced, the probe on the front side needs to be disassembled, thereby reducing the replacement rate of the turntable.

[0004] In order to solve the above problems, the present application proposes a novel rotation monitoring device for preventing mechanical accidental collision. Utility Model Content

[0005] To solve the problems raised in the above background technology. The utility model provides a new type of rotation monitoring device to prevent mechanical accidental collision, which has the feature of changing the installation of the proximity switch from the vertical front of the turntable to the vertical side installation, and the turntable on the rotating shaft does not need to be punched, and a protruding iron sheet is set on the outer periphery of the turntable, so that the distance between the proximity switch and the turntable is no longer affected when the driven wheel shaft shakes horizontally, thereby protecting the proximity switch from the risk of being damaged and reducing the maintenance rate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel rotation monitoring device for preventing mechanical accidental collision, comprising a fixed seat, a rotating shaft installed on one side of the fixed seat, and a rotating disk fixedly installed on one end of the rotating shaft, wherein a monitoring mechanism is arranged on the surface of the rotating disk;

[0007] The monitoring mechanism comprises a mounting bracket fixedly connected to one side of a turntable on the surface of the fixing seat and a proximity switch mounted on the surface of the mounting bracket. A plurality of groups of iron sheets are mounted on the surface of the turntable.

[0008] As a preferred embodiment of the novel rotation monitoring device for preventing mechanical accidental collision of the utility model, a monitoring probe is installed on the side of the proximity switch surface close to the iron sheet, and a warning light is installed on the side of the proximity switch surface away from the monitoring probe.

[0009] As a preferred embodiment of the novel rotation monitoring device for preventing mechanical accidental collision of the utility model, the cross section of the iron sheet is an L-shaped structure, and is welded and fixed on the surface of the turntable in a ring array.

[0010] As a preferred novel rotation monitoring device for preventing mechanical accidental collision of the utility model, a mounting mechanism is arranged on the surface of the mounting bracket, and the mounting mechanism includes a mounting block fixedly connected to the outside of the proximity switch and limit blocks symmetrically arranged on the upper and lower sides of the mounting block in an L-shaped structure, and the adjacent sides of the two groups of limit blocks are fixedly connected with a connecting rod, and the connecting rod is slidably connected to the inside of the mounting bracket, and the end of the connecting rod away from the limit block is fixedly connected with a pressing block, and a first spring is fixedly connected between the pressing block and the mounting bracket.

[0011] As a preferred embodiment of the novel rotation monitoring device for preventing mechanical accidental collision of the utility model, a frame-shaped groove is provided on the surface of the mounting block, and the size of the limit block matches that of the frame-shaped groove.

[0012] As a preferred new type of rotation monitoring device for preventing mechanical accidental collision of the utility model, a card block with a T-shaped structure is slid out and connected to one side of the mounting block inside the mounting bracket, and one end of the card block is located on the outside of the mounting bracket, a second spring is fixedly connected between the card block and the mounting bracket, and a card groove is opened on the surface of the connecting rod close to the card block.

[0013] Compared with the prior art, the utility model has the following beneficial effects: by setting a monitoring mechanism, the iron sheet cooperates with the proximity switch to monitor the rotation of the turntable, and there is no need to open holes on the surface of the turntable. When the turntable shakes horizontally, the distance between the proximity switch and the turntable is no longer affected, thereby protecting the risk of the proximity switch being damaged and reducing the maintenance rate. The iron sheet can be installed on the turntable by welding. As long as the installation position and distance of the proximity switch are adjusted before the first installation of the mounting bracket, the replacement and maintenance of the proximity switch are convenient, and the installation is convenient. After the proximity switch is installed, since the swing distance of the turntable is limited, as long as the length of the iron sheet is sufficient, the swing of the turntable back and forth to cause the change of the position of the turntable to affect the measurement effect is avoided. At the same time, the proximity switch will not affect the installation and removal of the turntable, thereby improving the convenience of installing or removing the turntable. At the same time, an installation mechanism is set, and the limit block can be pushed by two groups of pressing blocks to release the limit of the installation block, which is convenient for disassembling the proximity switch. The installation block is inserted between the two groups of limit blocks and the card block is pushed to move, so that the two groups of limit blocks can clamp the proximity switch, and the proximity switch can be quickly installed.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 As shown:

[0027] A novel rotation monitoring device for preventing mechanical accidental collision comprises a fixing seat 1, a rotating shaft 2 installed on one side of the fixing seat 1, and a rotating disk 5 fixedly installed on one end of the rotating shaft 2.

[0028] In this embodiment: "During operation, due to the movement of the rotating shaft 2, the turntable 5 may shake, causing the distance between the turntable 5 and the probe to change. The monitoring device is sometimes far away from the turntable 5 and sometimes close, which can easily damage the probe of the monitoring device and damage the equipment. When the turntable 5 is disassembled and replaced, the front probe needs to be disassembled, thereby reducing the replacement rate of the turntable 5." In terms of combined use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a monitoring mechanism 3 and an installation mechanism 4 are added to the application document.

[0029] More specifically:

[0030] like Figure 1-Figure 4 As shown:

[0031] In combination with the above content, the monitoring mechanism 3 includes a mounting bracket 32 ​​fixedly connected to one side of the turntable 5 on the surface of the fixing base 1 and a proximity switch 33 installed on the surface of the mounting bracket 32. A plurality of groups of iron sheets 31 are installed on the surface of the turntable 5.

[0032] In this embodiment: the iron sheet 31 cooperates with the proximity switch 33 to monitor the rotation of the turntable 5. The iron sheet 31 can be installed on the turntable 5 by welding, and there is no need to open holes on the surface of the turntable 5. When the turntable 5 shakes horizontally, it no longer affects the distance between the proximity switch 33 and the turntable 5, thereby protecting the risk of the proximity switch 33 being damaged and reducing the maintenance rate. As long as the installation position and distance of the proximity switch 33 are adjusted before the first installation of the mounting bracket 32, the replacement and maintenance of the proximity switch 33 are convenient, and the installation is convenient. At the same time, the proximity switch 33 will not affect the installation and removal of the turntable 5, thereby improving the convenience of installing or removing the turntable 5.

[0033] Going further:

[0034] like Figure 1-Figure 4 As shown:

[0035] In order to monitor the rotation of the turntable 5, in an optional embodiment: a monitoring probe 35 is installed on the side of the proximity switch 33 surface close to the iron sheet 31, and a warning light 34 is installed on the side of the proximity switch 33 surface away from the monitoring probe 35; the cross-section of the iron sheet 31 is L-shaped and is welded and fixed to the surface of the turntable 5 in a circular array.

[0036] In this embodiment: the iron sheet 31 can be sensed by the monitoring probe 35. During the rotation of the turntable 5, the warning light 34 turns on when the monitoring probe 35 senses the iron sheet 31 on the turntable 5, and turns off when the monitoring probe 35 senses the gap between adjacent iron sheets 31. Therefore, the rotation of the turntable 5 is monitored by flashing the warning light 34 on the proximity switch 33. When the shaft 2 does not rotate, the turntable 5 does not rotate, and the warning light 34 is in a state of being always on or off.

[0037] It should be noted that the proximity switch 33 is electrically connected to an external power supply through a wire. The proximity switch 33 consists of a warning light 34 and a monitoring probe 35. The proximity switch 33 is a switch that can be operated without mechanical contact with moving parts, also known as a contactless switch. When an object approaches the monitoring probe 35 of the proximity switch 33 to the operating distance, the monitoring probe 35 can be activated (lit up) without mechanical contact or application of any pressure.

[0038] More specifically:

[0039] like Figure 1-Figure 4 As shown:

[0040] In combination with the above content, a mounting mechanism 4 is provided on the surface of the mounting bracket 32, and the mounting mechanism 4 includes a mounting block 42 fixedly connected to the outside of the proximity switch 33 and limit blocks 41 symmetrically arranged on the upper and lower sides of the mounting block 42 in an L-shaped structure, and the adjacent sides of the two groups of limit blocks 41 are fixedly connected to a connecting rod 43, and the connecting rod 43 is slidably connected to the inside of the mounting bracket 32, and the end of the connecting rod 43 away from the limit block 41 is fixedly connected to a pressing block 46, and a first spring 45 is fixedly connected between the pressing block 46 and the mounting bracket 32; a frame-shaped groove is opened on the surface of the mounting block 42, and the size of the limit block 41 matches the frame-shaped groove.

[0041] In this embodiment: when the proximity switch 33 needs to be disassembled, the first spring 45 is squeezed and contracted by pressing the pressing blocks 46 on both sides, and the two sets of limit blocks 41 are pushed to move by the connecting rod 43 to release the limit on the installation block 42, so that the proximity switch 33 can be removed, thereby improving the convenience of maintenance of the proximity switch 33.

[0042] Going further:

[0043] like Figure 1-Figure 4 As shown:

[0044] In order to improve the convenience of installing the proximity switch 33, in an optional embodiment: a T-shaped block 44 is slidably connected to one side of the mounting block 42 inside the mounting bracket 32, and one end of the block 44 is located on the outside of the mounting bracket 32, a second spring 48 is fixedly connected between the block 44 and the mounting bracket 32, and a slot 47 is opened on the side of the surface of the connecting rod 43 close to the block 44.

[0045] In this embodiment: when the pressing block 46 pushes the limit block 41 to open through the connecting rod 43, the slot 47 on the connecting rod 43 is flush with the block 44, and then the block 44 is clamped into the slot 47 by the elastic force of the second spring 48 to limit the connecting rod 43. When installing the proximity switch 33, the mounting block 42 is aligned with the mounting bracket 32 ​​by moving the proximity switch 33, and then the mounting block 42 is pushed and placed between the two groups of limit blocks 41. The mounting block 42 will push the block 44 to move, so that the block 44 slides out of the slot 47, releasing the limit on the connecting rod 43. The pressing block 46 will be pulled by the elastic force of the first spring 45 to move the two groups of limit blocks 41 through the connecting rod 43, and the mounting block 42 is clamped and limited by the limit block 41 to complete the installation of the proximity switch 33.

[0046] Working principle: The monitoring probe 35 can sense the iron sheet 31. During the rotation of the turntable 5, the warning light 34 turns on when the monitoring probe 35 senses the iron sheet 31 on the turntable 5, and turns off when the gap between adjacent iron sheets 31 is sensed. Therefore, the rotation of the turntable 5 is monitored by flashing the warning light 34 on the proximity switch 33. When the rotating shaft 2 does not rotate, the turntable 5 does not rotate, and the warning light 34 is in a state of being always on or off. When the proximity switch 33 needs to be disassembled, the pressing blocks 46 on both sides are pressed to squeeze the first spring 45 to contract, and the two sets of limit blocks 41 are pushed to move through the connecting rod 43 to release the limit on the mounting block 42, and the proximity switch 33 can be removed. During this period, the connecting rod The card slot 47 on 43 is flush with the card block 44, and then the card block 44 is clamped into the card slot 47 by the elastic force of the second spring 48 to limit the connecting rod 43. When installing the proximity switch 33, the mounting block 42 is aligned with the mounting bracket 32 ​​by moving the proximity switch 33, and then the mounting block 42 is pushed and placed between the two groups of limit blocks 41. The mounting block 42 will push the card block 44 to move, so that the card block 44 slides out from the inside of the card slot 47, releasing the limit on the connecting rod 43. The pressing block 46 will be pulled by the elastic force of the first spring 45 through the connecting rod 43 to move the two groups of limit blocks 41, and the mounting block 42 is clamped and limited by the limit block 41, completing the installation of the proximity switch 33, thereby improving the convenience of maintenance of the proximity switch 33.

[0047] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention to solve the problems raised in the above background technology.
