Description

Technical Field

[0001] This utility model relates to the field of cylinder opening technology, and in particular to a limiting and fixing opening device for special equipment with cylinder pressure bearing. Background Technology

[0002] The cylinder of pressure-bearing special equipment refers to a container used to withstand internal or external pressure, typically for storing or transporting media such as gases and liquids. They are widely used in boilers, pressure vessels, gas cylinders, chemical equipment, and other fields.

[0003] A search of the Chinese patent "Cylinder Hole Opening Device for Pressure-Bearing Special Equipment" (publication number CN222710873U) reveals that this utility model belongs to the field of cylinder hole opening technology, specifically a cylinder hole opening device for pressure-bearing special equipment. It includes a hole opening device base plate, a pressure-bearing equipment cylinder fixing component mounted on the top of the base plate, a cylinder hole opening component mounted on the top of the pressure-bearing equipment cylinder fixing component, and a lifting component mounted on the side of the cylinder hole opening component. The base plate has an internal clearance groove. The pressure-bearing equipment cylinder fixing component includes a fixing support block, with a fastening bolt threaded internally connected to the fixing support block. A fastening clamping block is fixedly connected to the end of the fastening bolt. A first cylinder limiting block is provided on the side of the fastening clamping block, and a connecting clip is integrally connected to the bottom of the first cylinder limiting block. This utility model makes fixing the cylinder more labor-saving and convenient, and prevents the cylinder from moving during drilling, thus preventing interference with the drilling work.

[0004] Although the aforementioned perforation device can clamp and fix the cylinder, when the cylinder is punched at one position and needs to be rotated to the next punching position, the operator needs to disassemble the clamping structure and re-press and fix the cylinder. The operation is not only cumbersome, but also the support structure of the cylinder in the aforementioned perforation device has a limited diameter, making it impossible to place cylinders of different diameters.

[0005] Therefore, a limiting and fixing opening device for special equipment with cylindrical pressure bearing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a limiting and fixing opening device for special equipment with cylindrical pressure bearing in order to solve the above-mentioned problems. It improves the problems that the above-mentioned limiting and fixing opening device for special equipment with cylindrical pressure bearing cannot rotate the cylinder and open holes in different directions, and that the cylinder support structure has a limited diameter and cannot be applied to cylinders of different diameters.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a limiting and fixing opening device for special equipment with cylindrical pressure bearing, comprising: a base plate and a base disposed above it, wherein a cover plate is hinged above the base plate, and grooves are provided inside the base plate and the cover plate.

[0008] A limiting component, wherein three limiting components are provided and evenly distributed in the grooves of the base and the cover plate;

[0009] The limiting component includes a push rod disposed in the groove, and a roller is provided at the telescopic end of the push rod.

[0010] Preferably, three limiting components are provided, and the three limiting components are arranged in an inverted isosceles triangle. Through the above design, the stability of the cylinder can be improved by using three-way extrusion when clamping the cylinder, while also maintaining the accuracy of the hole position of the cylinder opening.

[0011] Preferably, the limiting component further includes a movable shell disposed at the telescopic end of the push rod. The inner wall of the movable shell is movably connected to the roller via a rotating shaft. By providing the movable shell, the roller can be axially limited.

[0012] Preferably, a dual-axis motor is provided in the inner center of the movable shell. The output ends on both sides of the dual-axis motor are fixedly connected to the rollers. By providing the dual-axis motor, the rollers can be driven to rotate the cylinder, so that the cylinder can be rotated and holes can be opened in other parts of the cylinder without disassembling it.

[0013] Preferably, the rollers are provided with guide patterns on their surfaces, and the guide patterns on the surfaces of the two rollers are arranged opposite to each other. By providing guide patterns, pressure can be applied from both sides of the cylinder to the center of the cylinder when the rollers rotate, so that the cylinder can remain longitudinally centered and improve the accuracy of the opening.

[0014] Preferably, a guide rail is provided on one side of the base plate surface, and a lifting device is provided above the guide rail via a slide. A hole opener is provided at the lifting end of the lifting device. By providing the guide rail, the horizontal position of the hole can be adjusted. By providing the lifting device, the depth of the hole can be adjusted. By providing the hole opener, the surface of the cylinder can be opened.

[0015] Preferably, the surface of the cover plate has a slotted hole, and the hole opener is on the same axis as the slotted hole.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting push rods and movable shells in the limiting component, it is convenient for workers to place cylinders of different diameters on the base and cover plate for limiting. In addition, the three push rods are driven synchronously, which can also keep the position of the cylinder horizontally centered and ensure the opening accuracy of each part.

[0018] 2. By setting up a dual-axis motor and rollers in the limit assembly, the angle of the cylinder can be adjusted without disassembling the cylinder when workers need to drill holes in multiple parts of the cylinder. The angle adjustment accuracy is high, which can reduce the positional distortion caused by human intervention. At the same time, the guide texture on the roller surface can also push the cylinder from both sides towards the center when the roller rotates, so that the cylinder remains longitudinally centered and improves the accuracy of drilling.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In practical implementation: such as Figure 1-4 As shown, a limiting and fixing opening device for special equipment with cylindrical pressure bearing includes: a base plate 1 and a base 5 disposed on the base plate 1, a cover plate 6 is hinged to the top of the base 5, and grooves are provided inside the base plate 1 and the cover plate 6.

[0026] The cylinder of pressure-bearing special equipment refers to a container used to withstand internal or external pressure. It is usually used to store or transport media such as gases and liquids. The main purpose of the openings in the cylinder of pressure-bearing special equipment is to install equipment for testing, maintenance, cleaning, heating or cooling. The design and location of the openings usually need to be precisely calculated to ensure the safety and functionality of the equipment. The openings make it easier to inspect the inside of the equipment, especially when performing regular inspections and maintenance on pressure vessels. The openings provide the necessary passage. In addition, the openings can also allow the entry and exit of media, such as the injection and discharge of liquids and gases, to ensure the normal operation of the equipment.

[0027] Limiting component 7, three of which are evenly distributed in the grooves of the base 5 and the cover plate 6;

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the limiting component 7 includes a push rod 702 disposed in the groove, and a roller 703 is disposed at the telescopic end of the push rod 702; three limiting components 7 are provided, and the three limiting components 7 are arranged in an inverted isosceles triangle; the limiting component 7 also includes a movable shell 701 disposed at the telescopic end of the push rod 702, and the inner wall of the movable shell 701 is movably connected to the roller 703 through a rotating shaft;

[0029] First, the staff placed the cylinder to be drilled into the base 5, and then closed the cover plate 6;

[0030] At this time, the three push rods 702 open together and push the movable shell 701. The three movable shells 701 are relatively close and squeeze the cylinder. At this time, the cylinder will be squeezed to the middle of the base 5 and the cover plate 6 by the rollers 703 inside the three movable shells 701. This not only keeps the cylinder horizontally centered and keeps the opening depth of each part of the cylinder consistent, but also allows for positioning of cylinders of different diameters.

[0031] It should be noted that during the above-mentioned clamping operation of the cylinder, the dual-axis motor 704 is in a stopped state, and the roller 703 will not rotate due to the squeezing of the cylinder. Therefore, there will be no phenomenon of the cylinder rotating after being clamped by the roller 703. Furthermore, the roller 703 is a rubber wheel. The rubber is relatively soft and can generate a certain friction force with the surface of the cylinder when in contact with it, which can stably clamp and limit the cylinder.

[0032] A dual-axis motor 704 is installed in the center of the movable housing 701, and the output ends on both sides of the dual-axis motor 704 are fixedly connected to the roller 703.

[0033] At this point, the staff can use the guide rail 4 to adjust the lateral position of the hole opener 3. After the adjustment is completed, the lifting device 2 will move the hole opener 3 down, and the driving end of the hole opener 3 will pass through the strip hole and extend into the cover plate 6 to open the cylinder.

[0034] After the hole in this part is opened, the staff can also drive the rollers 703 to rotate through three dual-axis motors 704, so that the three sets of rollers 703 can rotate in the same direction and make the cylinder rotate, so as to open the next part of the cylinder. This can achieve the effect of flipping the cylinder without disassembling it, which can improve the convenience of opening the cylinder, and at the same time maintain the stability of the cylinder during opening, and improve the quality of opening.

[0035] The surface of the roller 703 is provided with guide patterns 705, and the guide patterns 705 on the surfaces of the two rollers 703 are arranged opposite to each other;

[0036] When the dual-axis motor 704 controls the roller 703 to rotate, since the guide pattern 705 is designed with opposite sides and the line is oblique, it can use the friction between its surface and the cylinder to apply pressure from both sides of the cylinder to the middle, so that the cylinder can be kept in the axial middle of the cover plate 6 and the base 5, which can prevent the position from shifting and causing the opening position to deviate.

[0037] A guide rail 4 is provided on one side of the surface of the base plate 1. A lifting device 2 is provided above the guide rail 4 via a slide. A hole opener 3 is provided at the lifting end of the lifting device 2. A strip hole is provided on the surface of the cover plate 6. The hole opener 3 and the strip hole are on the same axis.

[0038] It should be noted that: the above-mentioned guide rail 4 is an electric guide rail 4, which is equipped with a slide block inside. The upper part of the slide block is fixedly connected to the housing of the lifting device 2. The housing is equipped with a lead screw through a bearing seat inside. The upper part of the housing is equipped with a motor. The output end of the motor passes through the housing and is fixedly connected to the lead screw. The surface of the lead screw is threaded with a threaded sleeve. The surface of the threaded sleeve is equipped with a connecting plate. The surface of the connecting plate is provided with a fixing hole. The hole opener 3 is set in the fixing hole of the connecting plate through a connecting bracket. In actual use, the guide rail 4 can adjust the horizontal position of the hole through the slide block. At the same time, the output end of the motor drives the threaded sleeve through the lead screw to adjust the height of the hole opener 3 inside the threaded sleeve. It can also adjust the hole depth of the cylinder. Finally, the hole opener 3 can be used to open the surface of the cylinder.

[0039] The aforementioned guide rail 4, dual-axis motor 704, slide block, motor, lead screw, threaded sleeve, and hole opener 3 are all relatively mature products in the existing technology. Among them, the guide rail 4 and motor have built-in power supplies. The specific models of the above structures can be selected as needed. The specific usage steps and principles can be found on the webpage and will not be elaborated here.

[0040] In practical use, the operator first places the cylinder to be drilled in the base 5, then closes the cover plate 6. At this time, the three push rods 702 open together and push the movable shells 701. The three movable shells 701 move closer together and squeeze the cylinder. The cylinder is then squeezed to the center of the base 5 and the cover plate 6 by the rollers 703 inside the three movable shells 701. This not only keeps the cylinder horizontally centered and the drilling depth of each part of the cylinder consistent, but also allows for positioning of cylinders of different diameters. The operator can then use the guide rail 4 to move the drill bit 3 horizontally. After the adjustment is completed, the lifting device 2 drives the hole opener 3 to move down. The driving end of the hole opener 3 will pass through the strip hole and extend into the cover plate 6 to open the cylinder. After the opening of this part is completed, the operator can also drive the roller 703 to rotate through three dual-axis motors 704, so that the three sets of rollers 703 can rotate in the same direction and make the cylinder rotate to open the next part of the cylinder. This achieves the effect of turning the cylinder without disassembly, which can improve the convenience of opening the cylinder and also maintain the stability of the cylinder during opening, thus improving the opening quality.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
