Description

Technical Field

[0001] This utility model relates to the field of automation instrumentation technology, specifically to a support device for industrial automatic control instruments. Background Technology

[0002] Industrial automation instruments are instruments used to detect, display, record, or control process parameters during industrial production. They are also called industrial instruments or (industrial) process detection and control instruments. Detection of the production process is a fundamental means of understanding and controlling industrial production. Only by accurately understanding the entire process at any time and controlling it can we ensure smooth production and produce qualified products with high productivity and low consumption.

[0003] Chinese Patent Publication No. CN216692874U discloses a novel adjusting base for industrial automatic control instruments, comprising a support base and an automatic control instrument. The support base includes a base plate and two columns fixed to the top of the base plate. Bearings are fixedly connected inside each of the two columns, and a common rotating shaft is fixedly connected inside each of the two bearings. A connecting seat located between the two opposing columns and fixedly connected to one side of the automatic control instrument is fixedly connected to the outer side of the rotating shaft. A cavity is provided inside the left end of the rotating shaft, and four openings are formed on the outer surface of the rotating shaft, each communicating with the cavity. The left end of the left column is fixedly connected to a U-shaped ring block located outside the rotating shaft. The left side wall of the inner cavity of the U-shaped ring block has a ring-shaped, equidistant insertion positioning groove. The cavity is equipped with a telescopic component, which includes a thrust recess. The outer surface of the thrust recess is fixedly connected to four insertion positioning rods that pass through the four clearance holes and extend into the insertion positioning grooves. The left side of the thrust recess is fixedly connected to a push button that extends to the left side of the U-shaped ring block. The interior of both columns is fixedly connected to a first spring, and the top of the two first springs is equipped with the same storage component.

[0004] However, this device achieves the storage effect by being fitted onto the outside of the automatic control instrument with a storage component, thus preventing dust from the air from adhering to the surface of the automatic control instrument when it is not in use. However, this device cannot adapt to various specifications and models of control instruments and can achieve a good placement effect, so its overall practicality is somewhat lacking. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the prior art, namely that the device cannot adapt to various specifications and models of control instruments and its overall practicality is not good.

[0006] A support device for an industrial automatic control instrument is proposed, including the automatic control instrument, a clamping device, a dust cover, a lifting device, and a drive assembly. The clamping device is located above the lifting device and connected to the lifting device. The automatic control instrument is disposed inside the clamping device. The dust cover is located above the clamping device and covers the automatic control instrument. The lifting device is located below the clamping device. The drive assembly is disposed at one end of the lifting device and connected to the lifting device.

[0007] In this utility model's technical solution, when an automatic control instrument needs to be fixed, the clamping device clamps and fixes the side walls of the automatic control instrument from both sides using clamping plates, thereby fixing the position of the automatic control instrument. The clamping plates are inserted and connected to the movable plate via plug-in plates. Therefore, when needed, the clamping plates can be selected according to the model of the automatic control instrument, thus adapting to different models of automatic control instruments through different types of clamping plates. This solves the shortcoming mentioned in the technical background that the device cannot adapt to achieve a good placement effect for various specifications and models of control instruments, resulting in poor overall practicality.

[0008] In a preferred embodiment of the present invention, the drive assembly includes a mounting box, a motor, driven wheels, a drive wheel, and a chain. The mounting box is connected to the end of the housing. The motor is located outside the mounting box and connected to the drive wheel. There are two driven wheels, both located inside the mounting box, with the two driven wheels respectively located at both ends of the mounting box. The two driven wheels are respectively connected to two threaded rods inside the lifting device. There are two drive wheels, both located in the middle of the two driven wheels. There are two sets of chains, each sleeved on one set of drive wheels and one set of driven wheels. After the motor is started, it can drive the drive wheels and driven wheels to rotate via the chain, thereby driving the threaded rods to rotate, and then driving the lifting plate to move up and down via the threaded rods. The chain used is a roller chain, and both the driven wheels and the drive wheel are sprockets.

[0009] In a preferred embodiment of the present invention, the lifting device includes a housing, a rotating rod, a movable block, a lifting plate, and a threaded rod. The lifting plate is positioned above the housing. There are two threaded rods, both located below the lifting plate and positioned on opposite sides of the lifting plate. Each threaded rod has a movable block at both ends, and both movable blocks are threadedly connected to the threaded rod. Each movable block has a rotating rod on its outer side, with both ends of the rotating rod hinged to the lifting plate and the movable block, respectively. The drive assembly is located at one end of the housing and connected to the two threaded rods. When the height of the automatic control instrument needs to be adjusted, the rotating rod can be rotated via the movable block. When the rotating rod rotates, it can move the lifting plate and the automatic control instrument up and down.

[0010] In a preferred embodiment of the present invention, the lower part of the housing is provided with braked casters. After the automatic control instrument moves to the required position, the casters can be locked to restrict the position of the automatic control instrument and the lifting device, thereby preventing the automatic control instrument from shifting.

[0011] In a preferred embodiment of the present invention, the clamping device is connected to the lifting plate, and when it is necessary to fix the automatic control instrument, the clamping device can clamp and restrict the automatic control instrument.

[0012] In a preferred embodiment of the present invention, the clamping device includes an electric slide, a movable plate, a plug-in plate, a damping rotator, and a clamping plate. The electric slide is connected to a lifting plate. There are two movable plates, each located at one end of the electric slide and vertically connected to the slide. The plug-in plate is vertically connected to the movable plate. Each plug-in plate is connected to a clamping plate via a damping rotator. The two clamping plates are located inside the two plug-in plates. An automatic control instrument is mounted on the clamping plate, and a dust cover is fitted over the instrument. The clamping plate is vertically inserted into the movable plate via the plug-in plate. Therefore, the size of the clamping plate can be changed to accommodate different sizes of automatic control instruments when needed.

[0013] In a preferred embodiment of the present invention, the two clamping plates are provided with anti-slip strips made of rubber. The rubber can increase the friction between the clamping plates and the automatic control instruments, thereby preventing the automatic control instruments from slipping off the clamping plates.

[0014] In a preferred embodiment of the present invention, a placement frame is provided on the inner wall of the dust cover, and a desiccant is placed in the placement frame. The desiccant absorbs the moisture inside the dust cover, thereby preventing the inside of the dust cover from becoming too damp, avoiding malfunctions or damage to the electronic components inside the automatic control instrument, and improving the practicality of the device.

[0015] The advantages of this utility model compared with the prior art are:

[0016] In use, this utility model allows for the replacement of clamping plates of different sizes according to the model of the automatic control instrument, thereby ensuring that the clamping assembly can clamp and fix different models of automatic control instruments. The dust cover is equipped with a desiccant, which absorbs moisture inside the dust cover to prevent it from becoming too damp and to avoid malfunctions or damage to the electronic components inside the automatic control instrument. When it is necessary to adjust the height of the automatic control instrument, it can be adjusted by the lifting device to ensure that the automatic control instrument is at the required height.

Detailed Implementation

[0030] The following will refer to the appendix in the embodiments of this utility model. Figure 1-12 The technical solutions in the embodiments of this utility model will be described in detail below.

[0031] like Figure 1-2 As shown, a support device for an industrial automatic control instrument includes an automatic control instrument 1, a clamping device 2, a dust cover 3, a lifting device 4, and a drive assembly 5. The clamping device 2 is disposed above the lifting device 4, and the automatic control instrument 1 is disposed inside the clamping device 2.

[0032] like Figure 1-2 As shown, when it is necessary to adjust the height of the automatic control instrument 1, the height of the clamping device 2 can be adjusted up and down by the lifting device 4. When the clamping device 2 moves up and down under the drive of the lifting device 4, it will synchronously drive the automatic control instrument 1 to move up and down.

[0033] like Figure 1-2 As shown, the height of the automatic control instrument 1 is adjusted in this way. The dust cover 3 is set above the lifting device 4 and covers the automatic control instrument 1. The drive device is set at one end of the lifting device 4 and connected to the lifting device 4.

[0034] like Figure 3-6 As shown, the drive assembly 5 includes a mounting box 51, a motor 52, a driven wheel 53, a driving wheel 54, and a chain 55. The mounting box 51 is located at the end of the housing 41 and is connected to the housing 41 by screws.

[0035] like Figure 3-6 As shown, there are two driven wheels 53, and both driven wheels 53 are located inside the mounting box 51. The two driven wheels 53 are respectively located at both ends of the mounting box 51. There are two driving wheels 54, and both are located inside the mounting box 51. The two driving wheels 54 are coaxially arranged and located in the middle position between the two driven wheels 53.

[0036] like Figure 3-6 As shown, there are two chains 55, which are respectively fitted onto two sets of driven wheels 53 and driving wheels 54. Both driven wheels 53 and driving wheels 54 are sprockets, and the chains 55 are roller chains. Therefore, when the driving wheel 54 rotates, it can drive the two driven wheels 53 to rotate synchronously through the chains 55.

[0037] like Figure 3-6 As shown, a motor 52 is provided on the outside of the mounting box 51. The motor 52 is connected to the mounting box 51 by screws. The output shaft of the motor 52 passes through the mounting box 51 and is located inside the mounting box 51. The drive wheel 54 is connected to the output shaft of the motor 52 by a key.

[0038] like Figure 3-6 As shown, once the motor 52 is started, it can drive the drive wheel 54 to rotate. When the drive wheel 54 rotates, it will drive the driven wheel 53 to rotate through the chain 55.

[0039] like Figure 7-8 As shown, the lifting device 4 includes a housing 41, a rotating rod 42, a moving block 43, a lifting plate 44, and a threaded rod 45. The lifting plate 44 is located above the housing 41, and the threaded rod 45 is located in a pre-set groove inside the housing 41 (the thread on the threaded rod 45 is a rectangular thread).

[0040] like Figure 7-8 As shown, two threaded rods 45 are rotatably connected to the housing 41 via bearings. One end of each threaded rod 45 passes through the housing 41 and is located inside the mounting box 51. Two driven wheels 53 are connected to the two threaded rods 45 via pins. The threads of the two threaded rods 45 are opposite in direction.

[0041] like Figure 7-8 As shown, when the driven wheel 53 rotates, it can drive the threaded rod 45 to rotate synchronously. Each threaded rod 45 has a moving block 43 at both ends. The moving block 43 is slidably disposed in the housing 41, and both moving blocks 43 are threadedly connected to the threaded rod 45.

[0042] like Figure 7-8 As shown, when the threaded rod 45 rotates, it can drive the moving block 43 to slide. Each moving block 43 has a rotating rod 42 on one side. The two ends of the rotating rod 42 are respectively hinged to the moving block 43 and the lifting plate 44. The rotating rod 42 is set in the preset groove of the box body 41.

[0043] like Figure 7-8 As shown, when the driven wheel 53 drives the threaded rod 45 to rotate clockwise, the threaded rod 45 will drive the moving blocks 43 at both ends to slide towards the center of the housing 41. When the moving blocks 43 slide towards the center of the housing 41, the moving blocks 43 can lift the lifting plate 44 upward through the rotating rod 42.

[0044] like Figure 7-8 As shown, conversely, when the driven wheel 53 drives the threaded rod 45 to rotate counterclockwise, the threaded rod 45 will drive the moving blocks 43 at both ends to slide towards the two ends of the housing 41 respectively. When the moving blocks 43 slide towards the two ends of the housing 41...

[0045] like Figure 7-8As shown, the moving block 43 can drive the lifting plate 44 to move downward through the rotating rod 42. There are also four brake-type universal wheels 6 at the bottom of the box body 41, which are respectively set at the four corners of the box body 41, and all four brake-type universal wheels 6 are vertically connected to the box body 41 by screws.

[0046] like Figure 7-8 As shown, when the automatic control instrument 1 needs to be moved, the housing 41 can be moved by the braked casters 6, thereby moving the position of the clamping device 2 and the automatic control instrument 1 using the housing 41.

[0047] like Figure 7-8 As shown, after the automatic control instrument 1 is moved to the desired position, the brake on the brake-type caster 6 can be used to lock the caster, thereby preventing the caster from shifting.

[0048] like Figure 9-11 As shown, the clamping device 2 includes an electric slide 21, a movable plate 22, a plug-in plate 23, a damping rotator 24, and a clamping plate 25. The electric slide 21 is arranged above the lifting plate 44 along the length direction of the lifting plate 44, and the electric slide 21 is connected to the lifting plate 44 by screws.

[0049] like Figure 9-11 As shown, the electric slide table 21 is provided with two sliders, and each slider is provided with a vertically mounted movable plate 22. The lower end of the movable plate 22 is attached to the slider, and each movable plate 22 is provided with a vertically mounted plug plate 23.

[0050] like Figure 9-11 As shown, the plug plate 23 is vertically inserted into the movable plate 22, and the outer side of the plug plate 23 is provided with a threaded hole, and a bolt is threaded into the threaded hole. After the plug plate 23 is inserted into the movable plate 22, the bolt can be rotated clockwise.

[0051] like Figure 9-11 As shown, the bolt is pressed against the movable plate 22 until the end of the bolt is pressed against the movable plate 22. At this point, displacement of the plug plate 23 on the movable plate 22 can be avoided. Each plug plate 23 is also provided with a clamping plate 25 on one side. The two clamping plates 25 are located inside the two movable plates 22.

[0052] like Figure 9-11 As shown, the clamping plate 25 is L-shaped. The plug plate 23 is connected to the clamping plate 25 through the damping rotator 24. The damping rotator 24 is connected to the plug plate 23 by screws. The output end of the damping rotator 24 is connected to the clamping plate 25.

[0053] like Figure 9-11As shown, each clamping plate 25 has an anti-slip strip 7 on its side wall. The anti-slip strip 7 is made of rubber and is bonded to the clamping plate 25. When it is necessary to fix the automatic control instrument 1, the automatic control instrument 1 is placed in the middle position of the two clamping plates 25.

[0054] like Figure 9-11 As shown, the electric slide 21 is turned on to drive the two moving plates 22 to move synchronously toward the automatic control instrument 1 until the clamping plate 25 clamps the side wall of the automatic control instrument 1 from both sides.

[0055] like Figure 9-11 As shown, the electric slide 21 can be turned off. The rubber anti-slip strip 7 can increase the friction between the clamping plate 25 and the automatic control instrument 1, thereby preventing the automatic control instrument 1 from slipping off the clamping plate 25. After the "L"-shaped clamping plate 25 clamps and fixes the automatic control instrument 1, the clamping plate 25 will also support the automatic control instrument 1 from below.

[0056] like Figure 12 As shown, the dust cover 3 is placed above the automatic control instrument 1. The lifting plate 44 has a groove at the lower end of the dust cover 3. After the dust cover 3 is placed on the automatic control instrument 1, the lower end of the dust cover 3 can be inserted into the preset groove on the lifting plate 44.

[0057] like Figure 12 As shown, the dust cover 3 has a desiccant 8 inside and a placement frame 31 on the inner wall of the dust cover 3. The placement frame 31 is adhered to the inner wall of the dust cover 3, and the desiccant 8 is placed in the placement frame 31 to absorb the moisture inside the dust cover 3.

[0058] like Figure 12 As shown, this avoids excessive moisture inside the dust cover 3, prevents malfunctions or damage to the electronic components inside the automatic control instrument 1, and improves the practicality of the device.

[0059] The movement process in this embodiment is as follows: After the automatic control instrument 1 is placed in the middle position of the two clamping plates 25, the electric slide 21 is turned on to drive the moving plate 22 to move in the direction of the automatic control instrument 1. After the clamping plates 25 clamp and fix the automatic control instrument 1.

[0060] The electric slide 21 can be turned off. Then, when the height of the automatic control instrument 1 needs to be adjusted, the motor 52 is turned on to drive the drive wheel 54 to rotate. When the drive wheel 54 rotates, it will drive the threaded rod 45 to rotate clockwise through the chain 55 and the driven wheel 53. When the threaded rod 45 rotates clockwise, it will lift the lifting plate 44 and the automatic control instrument 1 upward through the rotating rod 42.

[0061] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
