Description

Technical Field

[0001] The present application relates to the technical field of roller conveyor speed measuring devices, and in particular to a support frame and an infrared speed measuring device. Background Art

[0002] In electronic glass production, the stability of the annealing conveyor section plays a critical role in glass quality. The smooth operation of the roller conveyor has a crucial impact on the quality of the finished glass. Scratches and roller marks, two major defects in glass product quality, are caused by the annealing roller conveyor. Therefore, better and more precise control of roller conveyor speed is a top priority for glass production equipment. The original method for measuring roller conveyor speed was to use the feedback output signal from the frequency converter in the control system. Since the computer automatically calculates the speed, there is no basis for verifying whether there are any errors, so manual measurement and verification are required. Manual roller conveyor speed measurement involves using a handheld infrared speed meter to measure the time it takes for the roller to complete one rotation.

[0003] However, the above methods inevitably have human errors: 1. Manually holding the infrared speed meter will cause the infrared laser emission distance to change; 2. The handheld infrared speed meter will shake, resulting in distance errors in the measurement point.

[0004] At the same time, because the roller working area is a high-temperature area with pungent SO2 gas, long-term on-site speed measurement will cause certain damage to the workers' bodies.

[0005] Therefore, how to improve the speed measurement accuracy while protecting the speed measurement personnel is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0049] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.

[0051] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0052] See also Figure 1 、 Figure 4 and Figure 5An embodiment of the present application provides a support frame for supporting an infrared speedometer, including a frame body 100 and an installation assembly 200. The installation assembly 200 includes a receiving portion and an abutting portion. The receiving portion is connected to the frame body 100. The frame body 100 is used to support the receiving portion, and the receiving portion is used to receive the infrared speedometer. The abutting portion is connected to the receiving portion, and the abutting portion is used to abut the start button of the infrared speedometer.

[0053] Specifically, the above solution avoids the changes in infrared laser emission distance and shaking errors caused by manual holding by stably placing the infrared speed meter. The design of the abutment part ensures that the start button of the infrared speed meter is continuously and stably abutted, thereby improving the accuracy and stability of speed measurement.

[0054] When the support frame provided by the present invention is used, the frame body 100 is arranged at a preset position, and the infrared speedometer is arranged inside the accommodating portion. The operator sets a preset working time on the infrared speedometer, and then abuts the abutting portion against the start button of the infrared speedometer. The infrared speedometer starts speed measurement until the above working time ends. Such an arrangement can stably place the infrared speedometer, avoid manual speed measurement errors, and improve speed measurement accuracy. After the speed measurement is turned on, the abutting portion continuously abuts against the start button without the need for staff to follow up. That is, the use of the support frame allows the speed measurement personnel to only set up the support frame and the infrared speedometer at the preset position, and then move away from the speed measurement site to perform safe speed measurement operations. The speed measurement personnel do not need to follow up on the site for a long time to perform speed measurement, thereby avoiding damage to the body caused by high temperature and pungent gases, thereby protecting the speed measurement personnel.

[0055] In order to optimize the above technical solution, the frame 100 includes a connecting plate 101 and three or more supporting legs 102, one end of the supporting leg 102 is connected to the connecting plate 101, and the other end thereof is against the ground, and the side of the connecting plate 101 away from the supporting leg 102 is connected to the accommodating portion.

[0056] In some embodiments, the connecting plate 101 is welded to the support leg 102. In a support frame, a stable connection is an important guarantee for ensuring stable speed measurement of the infrared speed meter and preventing accidental falling. The connecting plate 101 and the support leg 102 are welded to ensure that the entire support frame has sufficient structural strength to withstand large loads and impact forces.

[0057] In other embodiments, the connecting plate 101 and the support leg 102 are connected by a rotating shaft 103, that is, the end of the support leg 102 connected to the connecting plate 101 is rotatably connected to the connecting plate 101 via the rotating shaft 103. The rotating shaft 103 connection allows a certain degree of rotational freedom between the connecting plate 101 and the support leg 102. This design allows the support frame to adjust the angle according to actual needs, thereby adapting to different working environments and speed measurement requirements. For example, in glass production, the rollers may be located at different heights and angles. By adjusting the angle between the support leg 102 and the connecting plate 101, it can be ensured that the infrared speed meter can be stably and accurately aligned with the rollers for speed measurement.

[0058] Furthermore, the connecting plate 101 is designed with a hole or groove that matches the rotating shaft 103 so that the rotating shaft 103 can be inserted and fixed. The shape and size of the hole or groove should match the rotating shaft 103 to ensure that the connecting plate 101 can rotate smoothly on the rotating shaft 103. The support leg 102 is designed with a bearing seat or hole that matches the rotating shaft 103 so that the rotating shaft 103 can be fixed on the support leg 102. The bearing seat can provide better support and rotation performance and reduce friction and wear.

[0059] The design of the connecting plate 101 and three or more supporting legs 102 makes the support frame more stable, capable of supporting the weight of the infrared speed meter and ensuring its stability during use. At the same time, the design of the supporting legs 102 also makes it easy to arrange the support frame in a preset position.

[0060] See also Figure 3 In order to optimize the above technical solution, the support frame also includes a lifting assembly 300, which includes a fixed frame 301, a rocker arm 302 and a first threaded rod 303, wherein the bottom of the fixed frame 301 is fixedly connected to the frame body 100, and a mounting hole for installing the rocker arm 302 is opened on one side of the fixed frame 301, the rocker arm 302 is arranged in a horizontal direction, and the rocker arm 302 is arranged perpendicular to the first threaded rod 303, the first end of the rocker arm 302 is arranged outside the fixed frame 301, and the second end thereof is connected to the end of the first threaded rod 303 away from the accommodating portion by a bevel gear transmission.

[0061] Specifically, the rocker arm 302 may be linear or L-shaped, and the L-shaped rocker arm 302 is more convenient for an operator to drive.

[0062] During use, the operator shakes the rocker arm 302. Since the rocker arm 302 is connected to the telescopic rod through a bevel gear transmission, the rotation of the rocker arm 302 will be converted into the rotation of the first threaded rod 303. When the first threaded rod 303 rotates, since its outer surface has threads, it drives the accommodating part to move in the vertical direction, thereby adjusting the height of the infrared speed meter inside the accommodating part.

[0063] This solution introduces a lifting assembly 300, which can drive the first threaded rod 303 to rotate through the rotation of the rocker arm 302, and then the accommodating part moves in the vertical direction through the threaded transmission mechanism. This design allows the height of the infrared speed meter to be easily adjusted to meet the speed measurement requirements of roller conveyors at different heights, thereby improving the speed measurement accuracy.

[0064] In order to optimize the above technical solution, the support frame also includes an extension component 400, which includes a telescopic rod, a connecting sleeve 405 and a first positioning portion, wherein the telescopic rod includes an outer rod 401 and an inner rod 402, the outer rod 401 is sleeved on the outside of the inner rod 402, and the inner rod 402 can move axially inside the outer rod 401, the interior of the connecting sleeve 405 is provided with a threaded hole that matches the first threaded rod 303, and the connecting sleeve 405 is sleeved on the circumference of the first threaded rod 303, the first end of the telescopic rod is fixedly connected to the connecting sleeve 405, and its second end is connected to the accommodating portion, the telescopic rod is arranged vertically to the first threaded rod 303, and the first positioning portion is arranged on the circumference of the outer rod 401 for locking the inner rod 402.

[0065] It should be noted that, through the solution in the above embodiment, the position of the infrared speed meter in the vertical direction can be adjusted, and this solution is used to adjust the position of the infrared speed meter in the horizontal direction.

[0066] Specifically, the inner rod 402 can move axially inside the outer rod 401, which is the key to realizing the telescopic function. When the length of the telescopic rod needs to be adjusted, the inner rod 402 will move axially inside the outer rod 401. The first positioning portion is used to ensure that the inner rod 402 can remain stable after moving to a preset position inside the outer rod 401.

[0067] Specifically, the outer rod 401 is fixedly connected to the connecting sleeve 405, and the inner rod 402 is connected to the accommodating portion.

[0068] During use, the operator rotates the rocker arm 302, and the rocker arm 302 drives the rotation of the first threaded rod 303. A threaded transmission mechanism is formed between the first threaded rod 303 and the connecting sleeve 405. In the threaded transmission, when the first threaded rod 303 rotates, the connecting sleeve 405 moves along the axial direction of the thread (i.e., the vertical direction), thereby driving the accommodating part to move along the vertical direction to adjust the height of the infrared speed meter inside the accommodating part.

[0069] During use, the operator adjusts the relative position of the inner rod 402 and the outer rod 401 so that the inner rod 402 moves axially inside the outer rod 401. When the inner rod 402 moves to the preset position, the first positioning part fixes the inner rod 402 on the outer rod 401. The structural form of the first positioning part includes but is not limited to a locking device, a snap buckle, etc.

[0070] This solution introduces an extension assembly 400, comprising a telescopic rod and a first positioning portion, further enhancing the flexibility and adaptability of the support frame. The design of the telescopic rod allows the housing (where the infrared speedometer is mounted) to move horizontally for better alignment with the roller conveyor. Furthermore, the first positioning portion secures the length of the telescopic rod, ensuring stability during measurement and improving speed measurement accuracy.

[0071] In order to optimize the above technical solution, the first positioning part includes a first handle 403, a first stud and a first screw 404, wherein the first stud is arranged on the circumference of the outer rod 401, the axial direction of the first stud is arranged perpendicular to the axial direction of the outer rod 401, and the first stud is provided with an internal thread matching the first screw 404, the first end of the first screw 404 is connected to the first handle 403, and its second end can abut against the inner rod 402 for locking the inner rod 402.

[0072] Specifically, the first end of the first screw rod 404 is connected to the first handle 403 to facilitate manual operation by the operator; the second end thereof abuts against the inner rod 402 to achieve positioning and fixation of the inner rod 402 .

[0073] During use, when the operator needs to adjust the position of the inner rod 402 in the outer rod 401, he first rotates the first handle 403, loosens the first positioning part, and disengages the first screw 404 from the internal thread of the first stud, thereby allowing the inner rod 402 to move axially inside the outer rod 401. After moving the inner rod 402 to the preset position, it is ready to be fixed. The first handle 403 is rotated in the opposite direction, and the second end of the first screw 404 gradually presses against the inner rod 402. When the first screw 404 is completely pressed against the inner rod 402, the inner rod 402 is firmly fixed at the preset position on the outer rod 401.

[0074] This design of the first positioning portion ensures the stability and safety of the inner rod 402 in the outer rod 401. Even under the action of external force, the inner rod 402 is not prone to accidental movement, thereby ensuring the overall stability and reliability of the support frame and thus ensuring the speed measurement accuracy.

[0075] By arranging the first positioning portion, the operator can conveniently adjust the length of the telescopic rod and fix the length by rotating the first screw 404, ensuring that the position of the infrared speed meter can be precisely adjusted as needed, thereby meeting the speed measurement accuracy requirements and improving the usability and accuracy of the support frame.

[0076] See also Figure 2 In order to optimize the above technical solution, the accommodating portion is a U-shaped groove, which includes a groove bottom and a first groove wall 202 and a second groove wall 203 arranged opposite to each other. The first groove wall 202 is connected to the inner rod 402, and the second groove wall 203 is connected to the abutting portion.

[0077] Arranging the receiving portion as a U-shaped groove provides a stable support surface for the infrared speedometer and facilitates the installation and removal of the infrared speedometer. At the same time, the first groove wall 202 is connected to the telescopic rod, and the second groove wall 203 is connected to the abutment portion, which facilitates subsequent speed measurement operations.

[0078] It should be noted that the accommodating portion can be of any shape, such as a lidless box shape, a cylindrical shape, etc., but arranging the accommodating portion as a U-shaped groove can facilitate the operator to take and place the infrared speed meter, so this application prefers that the accommodating portion is designed as a U-shaped groove.

[0079] In order to optimize the above technical solution, the abutment portion includes a rotating plate 201 and an abutment member. The rotating plate 201 is rotatably connected to the second groove wall 203, and the abutment member is connected to the rotating plate 201. The abutment member is used to abut the start button of the infrared speed meter.

[0080] It should be noted that the purpose of setting the rotating plate 201 is to provide flexibility and adaptability to meet the use requirements of the infrared speed meter in different scenarios or conditions.

[0081] Specifically, the rotatable connection between the rotating plate 201 and the second groove wall 203 allows the abutment portion to be adjusted in angle within a certain range. Even if the position or angle of the infrared speed meter changes, the abutment can more accurately abut against the start button of the infrared speed meter.

[0082] Specifically, because the positions and shapes of the start buttons of different models of infrared speed meters are different, the abutment can adapt to start buttons of different shapes and positions by adjusting the angle of the rotating plate 201. The operator can adjust the position of the abutment by simply rotating the rotating plate 201 without the need for complicated disassembly or reinstallation. On the one hand, it can ensure that the infrared speed meter can be started correctly, and on the other hand, it is convenient for the operator to operate.

[0083] Specifically, the rotating plate 201 and the second groove wall 203 can be connected by bolts to ensure that they will not loosen due to vibration or external force during use. At this time, the relative position of the rotating plate 201 and the second groove wall 203 can be changed by loosening and tightening the bolts.

[0084] Specifically, refer to Figure 6 The rotating plate 201 includes at least two fixing holes, one of which is used to fix the rotating plate 201 and the second groove wall 203, and the other fixing hole is used to fix the abutment. When the number of fixing holes is three or more, the operator can change the position of the abutment (connecting the abutment to the fixing holes in different positions) to change the position at which the abutment can abut, thereby adapting to start buttons in different positions.

[0085] Furthermore, a convex plate 2011 may be provided on the rotating plate 201 , and the convex plate 2011 is arranged perpendicular to the rotating plate 201 . The operator can move the rotating plate 201 by pulling the convex plate 2011 , which is convenient for operation.

[0086] Specifically, one or more abutment members may be arranged to further adapt to infrared speed meters of different models and arrangement positions, so that the support frame can be applied to various working conditions.

[0087] The above solution allows the operator to easily adjust the position and angle of the abutment member to better abut the start button of the infrared speed meter, thereby improving the accuracy and convenience of the speed measurement operation.

[0088] In order to optimize the above technical solution, the abutment portion also includes a second positioning portion, the second positioning portion includes a second handle 204, a second stud and a second screw 205, wherein the second stud is arranged on the second groove wall 203, the axial direction of the second stud is arranged perpendicular to the second groove wall 203, and the second stud is provided with an internal thread matching the second screw 205, the first end of the second screw 205 is connected to the second handle 204, and its second end abuts against the outer surface of the infrared speed meter.

[0089] Specifically, the first end of the second screw 205 is connected to the second handle 204 to facilitate manual operation by the operator; the second end thereof abuts against the outer surface of the infrared speedometer to achieve positioning and fixation of the infrared speedometer.

[0090] Specifically, the axial direction of the second stud is arranged perpendicular to the second groove wall 203, which ensures that the second stud can provide stable support and positioning functions.

[0091] During use, when the operator needs to fix the infrared speedometer inside the U-shaped groove, he rotates the second handle 204, and the second screw 205 moves axially inside the second stud. The second end of the second screw 205 gradually presses against the outer surface of the infrared speedometer, and the infrared speedometer is firmly fixed inside the U-shaped groove.

[0092] Furthermore, when the position or angle of the infrared speedometer needs to be adjusted, the staff can push or pull the second screw 205 by rotating the second handle 204, thereby fine-tuning the position of the infrared speedometer, that is, by adjusting the screw-in depth of the second screw 205, the infrared speedometer can be accurately positioned. Once the appropriate position is found, the threaded connection between the second screw 205 and the second stud will ensure that the infrared speedometer can be stably maintained at the desired position and angle.

[0093] This arrangement provides additional fixation and support for the infrared speedometer, ensuring stability during measurement. At the same time, the second screw 205 can abut against the outer surface of the infrared speedometer, further enhancing the connection stability of the infrared speedometer to further ensure speed measurement accuracy.

[0094] In order to optimize the above technical solution, the abutment includes a second threaded rod, a first nut, an abutment spring and a second nut, wherein the rotating plate 201 is provided with a threaded hole matching the second threaded rod, the first nut is arranged on the side of the rotating plate 201 away from the second groove wall 203, and is connected to the second threaded rod, the second nut is arranged on the side of the rotating plate 201 close to the second groove wall 203, and is connected to the second threaded rod, the abutment spring is sleeved on the outside of the second threaded rod, and is arranged between the rotating plate 201 and the second nut, and the second nut is used to abut the start button of the infrared speed meter.

[0095] Specifically, the second threaded rod is fixed to the rotating plate 201 through a threaded connection. The second threaded rod can rotate and move axially to a certain extent in the rotating plate 201. By rotating the first nut, the axial position of the second threaded rod in the rotating plate 201 can be adjusted, and the compression degree of the spring can be adjusted. One end of the abutment spring contacts the rotating plate 201, and the other end contacts the second nut, which is used to provide abutment force and buffering force. The position of the second nut is fixed and directly abuts the start button of the infrared speed meter.

[0096] In the initial state, the second nut has been positioned and abutted against the start button of the infrared speedometer. At this time, the abutment spring is in a certain compressed state, but the degree of compression can be adjusted as needed. During use, the operator rotates the second threaded rod, and the abutment spring is in a compressed state (since the position of the second nut is relatively fixed, the compression or release of the abutment spring will directly affect the abutment force of the second nut on the start button, and the degree of compression of the abutment spring is adjusted). After the adjustment is completed, the second nut will maintain a constant abutment force on the start button, and control the first nut to move in the direction close to the infrared speedometer to further fix the second threaded rod and the rotating plate 201. When the infrared speedometer needs to be started, the start button will be triggered by sufficient pressure from the second nut. Due to the buffering effect of the abutment spring, this abutment method can not only ensure a stable starting effect, but also protect the start button from excessive pressure.

[0097] This arrangement enables the abutment portion to continuously and stably abut the start button of the infrared speedometer, avoiding shaking and errors caused by manually holding the infrared speedometer.
