Description

Technical Field

[0001] The present invention relates to the technical field of equipment inspection, and particularly to an inspection device for mechanical engineering equipment. Background Art

[0002] Mechanical engineering equipment plays a crucial role in many fields such as industrial production and infrastructure construction, and its operating state directly affects production efficiency, product quality and safety. In industrial production, mechanical engineering equipment is the core element to maintain the efficient operation of the production line. From the automated welding robots that operate precisely in the automotive manufacturing workshop to the chip mounters with micron-level precision on the electronic component production line, their stable operation ensures product consistency and yield. Once the equipment fails, it will not only lead to production stagnation, causing direct economic losses, but may also trigger a chain reaction, disrupting the rhythm of the entire supply chain and affecting the enterprise's delivery capacity and market reputation. In terms of infrastructure construction, mechanical engineering equipment is an indispensable main force.

[0003] However, during the inspection of mechanical engineering equipment, a lift that can be raised and lowered is usually used. However, during the maintenance of a conventional lift, when holding a tool in one hand and grasping the handrail tightly with the other hand, there may be a situation of accidental dropping. In addition, sometimes to facilitate the work of the inspectors, there is usually someone assisting in handing tools beside. Since the assisting personnel beside need to move, there may be shaking when moving above the lift, which undoubtedly makes it more difficult for the inspectors with relatively low safety to conduct inspections. This patent aims to provide an inspection device for mechanical engineering equipment to alleviate the above-mentioned technical problems existing in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art. During the inspection of mechanical engineering equipment, a lift that can be raised and lowered is usually used. However, during the maintenance of a conventional lift, when holding a tool in one hand and grasping the handrail tightly with the other hand, there may be a situation of accidental dropping. In addition, sometimes to facilitate the work of the inspectors, there is usually someone assisting in handing tools beside. Since the assisting personnel beside need to move, there may be shaking when moving above the lift, which undoubtedly makes it more difficult for the inspectors with relatively low safety to conduct inspections. And an inspection device for mechanical engineering equipment is proposed.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A device for inspecting mechanical engineering equipment, comprising a base and a support frame. A stabilizing block is fixedly connected above the support frame. A rocker is rotatably connected to the stabilizing block. The rocker passes through the stabilizing block and is fixedly connected to a worm. The worm is meshed with a worm gear. The worm gear is drivingly connected to a winding roller. The rocker is drivingly connected to a connecting rod. One end of the connecting rod away from the rocker is drivingly connected to a lower plate gear. The lower plate gear is meshed with a protective rack. The protective rack is slidably connected to a seat plate. A lower connecting gear is fixedly connected to the bottom of the worm gear. The lower connecting gear is meshed with a sliding rack. A placing mechanism for placing tools is arranged on one side of the support frame. The placing mechanism comprises a mounting frame on the side of the support frame. A turntable is arranged on the side of the mounting frame. A convex column is eccentrically fixedly connected to the turntable. A through groove plate is arranged outside the convex column. A connecting strip is fixedly connected to the bottom of the through groove plate. The connecting strip is slidably connected to a track. A small part placing box is fixedly connected to the side of the through groove plate. A tool hanging rack is fixedly connected above the mounting frame.

[0007] The above technical solution further includes:

[0008] A wide rack is fixedly connected above the base. The wide rack is meshed with an in-slot gear. The in-slot gear is rotatably connected to a wide horizontal rack. The side of the wide horizontal rack is meshed with a cut gear. The cut gear is arranged in a groove of the support frame. An extending strip is arranged on the side of the support frame. The extending strip on the side of the support frame is slidably connected to the side of the wide horizontal rack. The worm gear is drivingly connected to a first belt. One end of the first belt away from the worm gear is drivingly connected to a winding roller. The rocker is drivingly connected to a second belt. One end of the second belt away from the rocker is drivingly connected to a connecting rod. The connecting rod is drivingly connected to a third belt. One end of the third belt away from the connecting rod is drivingly connected to a lower plate gear.

[0009] A connecting block is fixedly connected to the bottom of the seat plate. The connecting block is rotatably connected to a connecting rod. The seat plate is fixedly connected to the support frame. The support frame is fixedly connected to a pedal.

[0010] A motor is arranged on one side of the wide horizontal rack. The motor on the side of the wide horizontal rack penetrates its surface and is fixedly connected to the in-slot gear.

[0011] A support block for connecting a safety belt is arranged above the support frame. A cut is arranged on the side of the support frame. A cut gear is rotatably connected inside the cut on the side of the support frame.

[0012] The bottom of the retraction roller is rotatably connected to a support frame. A long slot for placing the lower connecting gear is formed on the surface of the support frame, and the lower connecting gear is rotatably connected to the support frame. The bottom of the retraction roller is rotatably connected to the support frame, and the lower connecting gear is placed in the long slot of the support frame and rotatably connected thereto. This structure realizes the effective linkage between the seat belt retraction and the transmission mechanism. While the seat belt tightens to fix the inspector, the lower connecting gear can transmit the rotational power of the retraction roller to the sliding rack, enabling the sliding rack to appear in front of the worker's abdomen in time to provide auxiliary support. This integrated transmission design not only ensures the realization of the safety protection function but also avoids the setting of an additional power source, simplifies the device structure, and improves the operation stability.

[0013] A long strip is fixedly connected to the side of the mounting frame, and the long strip on the side of the mounting frame is rotatably connected to the turntable. The connection between the long strip on the side of the mounting frame and the turntable provides a stable support basis for the eccentric circular motion of the turntable. This connection method enables the turntable to drive the convex column to move with a stable and precise trajectory during rotation, thereby ensuring that the through-channel plate realizes stable intermittent up-and-down movement to meet the operation requirements such as taking and placing tools from the tool hanger and pulling out and pushing in the drawer of the small parts placement box, ensuring the reliable operation of the tool access function, and improving the convenience of maintenance and inspection work.

[0014] A notch for the up-and-down sliding of the connecting strip is provided at the connection between the support frame and the mounting frame. The design of providing a notch for the up-and-down sliding of the connecting strip at the connection between the support frame and the mounting frame provides guidance and space for the movement of the connecting strip. During the up-and-down reciprocating movement of the through-channel plate, the connecting strip can slide stably along the notch, effectively preventing the through-channel plate from shifting or jamming, ensuring the stability and reliability of the operation of the through-channel plate driving the tool taking and placing mechanism, and ensuring that the inspector can smoothly access and return tools and parts.

[0015] Multiple groups of rollers for movement are provided at the bottom of the base. The provision of multiple groups of rollers at the bottom of the base enables the inspection device to have flexible mobility. The operator can easily push the device to different equipment inspection positions without the need for other handling tools, saving labor and time costs. At the same time, it is convenient for the device to quickly transfer between different operation scenarios, greatly improving the versatility and use efficiency of the inspection device and adapting to the diverse inspection requirements of mechanical engineering equipment.

[0016] A square opening for placing the legs is formed on the surface of the seat plate. The formation of a square opening for placing the legs on the surface of the seat plate conforms to the ergonomic design. When the inspector is seated, the square opening can provide a suitable placement space for the legs, avoiding fatigue caused by the legs being suspended or improperly placed, helping to maintain a comfortable working posture, and reducing physical discomfort caused by long-term operation. At the same time, reasonable leg placement also helps the inspector maintain body balance during operation, improving operation safety and comfort.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, through multiple protection structures such as seat belt contraction and fixation, automatic rising of the protection rack, and auxiliary support of the sliding rack, it effectively avoids accidental falling of the inspection personnel due to imbalance during operation. At the same time, the tool management system with the tool hanging rack, small part placement box, and through slot plate linkage enables the maintenance tools to be retrieved as needed without the need to hold them with one hand, completely eliminating the hidden danger of tool falling and comprehensively ensuring the safety of high-altitude operations.

[0019] 2. In the present invention, integrating height adjustment and lateral sliding functions, the inspection personnel can independently control the up and down lifting and left and right movement of the support frame to accurately reach the equipment inspection position. The built-in tool access mechanism realizes the automatic delivery of tools and parts through the eccentric movement of the turntable and the convex column, without the need for the cooperation of auxiliary personnel, reducing the platform shaking caused by personnel movement, and significantly improving the stability and working efficiency of the inspection operation.

[0042] In one embodiment, for the seat plate 5, a square opening for placing the legs is provided on the surface of the seat plate 5.

[0043] In this embodiment, a square opening for placing the legs is provided on the surface of the seat plate 5, which conforms to the ergonomic design. When the inspection personnel are seated, the square opening can provide a suitable space for the legs to be placed, avoiding fatigue caused by the legs being suspended or improperly placed, helping to maintain a comfortable working posture, and reducing physical discomfort caused by long-term operation. At the same time, reasonable leg placement also helps the inspection personnel to maintain body balance during operation, improving operation safety and comfort.

[0044] The working principle of an inspection device for mechanical engineering equipment in the present invention is as follows. First, the base 1 is moved to the lower side of the equipment to be inspected by using the rollers at the bottom, and then the operator sits above the seat plate 5. At this time, the rocker 12 is shaken, so that the worm 13 drives the worm gear 14 to rotate. The rotation of the worm gear 14 will drive the reel 16 to rotate by using the first belt 15. The rotation of the reel 16 will contract the safety belt on its surface. The other end of the safety belt is fixedly connected to the irregular block above the support frame 2. Therefore, the safety belt will fix the operator sitting above the seat plate 5. At the same time, the rotation of the rocker 12 will drive the connecting rod 20 to rotate by using the second belt 19. The connecting rod 20 will drive the gear under the plate 24 to rotate by using the third belt 23. The rotation of the gear under the plate 24 will engage with the protective rack 25, so that the protective rack 25 moves upward and appears inside the operator's thigh, thus preventing the accidental fall of the operator. However, when the worm gear 14 rotates, it will drive the lower connecting gear 18 at the bottom to rotate. The rotation of the lower connecting gear 18 will engage with the sliding rack 17, so that the sliding rack 17 appears in front of the operator's abdomen. Then, at this time, the internal gear 9 in the control groove is rotated. The rotation of the internal gear 9 in the control groove will engage with the rack wide column 3, so that the horizontal wide rack 4 slides upward, and then reaches the area where the equipment is located. Then, the cut gear 10 is controlled to rotate. The rotation of the cut gear 10 will engage with the rack on the side of the horizontal wide rack 4 Figure 1 as an example, so that the support frame 2 slides left and right on the side of the horizontal wide rack 4, which is convenient for the overall maintenance and inspection of the equipment.

[0045] Subsequently, during maintenance, by controlling the rotation of the turntable 26, the rotation of the turntable 26 will drive the convex column 28 to perform eccentric circular motion. The through groove plate 27 slides outside the convex column 28, so that the through groove plate 27 shows an intermittent up and down movement trend. A connecting strip 29 is fixedly connected to the bottom of the through groove plate 27, and the connecting strip 29 slides along the track 30 at the bottom, so as to ensure the stability of the up and down reciprocating sliding of the through groove plate 27. When it is necessary to take maintenance tools, the turntable 26 is controlled to rotate. When the convex column 28 reaches the Figure 6 lowest point in the figure, it is just possible to take the tools suspended on the surface of the tool hanger 7 for work. When taking parts, the turntable 26 is controlled to rotate. The rotation of the turntable 26 will drive the through groove plate 27 to have an up and down reciprocating trend. A small part placement box 8 is fixed on the side of the through groove plate 27. Then, the drawer on the surface of the small part placement box 8 can be pulled out to facilitate the taking of small parts. If it is necessary to return the tools above the tool hanger 7, similarly, the turntable 26 is controlled to rotate, so that the height that the through groove plate 27 can reach is placed above to replace or return the tools.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and permutations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
