Description

Technical Field

[0001] This utility model relates to the field of heat storage component processing technology, specifically to a heat storage component closing device. Background Technology

[0002] The heat storage element is made up of hundreds of thin iron sheets with stamped stripes, with cover plates and bottom plates on the top and bottom, and connected vertically by connecting ribs. After unpacking and cleaning, the iron sheets are deformed and the height increases. When the workers place them, they are uneven, which makes the subsequent reassembly extremely difficult. In the past, workers used hammers and hand-operated hoists to pull them, which seriously damaged the heat storage element and was inefficient.

[0003] The utility model patent with patent number CN02295585.2 relates to a large equipment assembly and alignment device for shipbuilding manufacturing. Its features are that it consists of a docking work platform, a traveling track, and a computer control system. The two longitudinal beams of the docking work platform are supported by a three-degree-of-freedom shipyard trolley below them. Under the unified control of the computer, the six-degree-of-freedom posture of the workpiece is adjusted. The workpiece assembly and alignment is completed within a few minutes, which greatly reduces the labor intensity. Moreover, the posture adjustment of the workpiece is completed in a stress-free state, which greatly improves the welding quality. However, the structure of this patent is complex and is not suitable for the assembly and processing of heat storage components. Utility Model Content

[0004] To address the problems mentioned in the background art, such as improper placement of the packaging pieces, difficulty in pressing, and low efficiency, this utility model provides a structurally sound, easy-to-operate, and highly efficient device for closing heat storage components.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heat storage element closure device includes a base, on which opposing columns are fixed, forming a space for placing the heat storage element between the base and the columns. An upper support beam is installed at the upper end of the columns, and a force-applying rod is installed on the upper support beam with its power output end facing downward and connected to an upper pressure beam. A power device is connected to the force-applying rod through a transmission mechanism. A push-side column is connected to the base on one side of the columns, and a side support beam is fixedly connected to the middle of the push-side column. A force-applying rod is fixedly connected to the side support beam, with its power output end facing the heat storage element and connected to a side pressure plate frame. A side-blocking column is connected to the base on the other side of the columns.

[0007] Preferably, the angle between the push post and the stop post and the base is adapted to the shape of the heat storage element.

[0008] Preferably, the side pressure plate frame and the force-applying rod are connected by a pin, and the pin passes through the corresponding connection hole on the side pressure plate frame and the force-applying rod.

[0009] Preferably, the force-applying rod is a hydraulic cylinder, and the corresponding power device is a hydraulic pump, with the two connected by a hydraulic oil pipe.

[0010] Preferably, the force-applying rod is an electric push rod, and the corresponding power device is a motor. The motor and a reducer are connected. The output shaft of the reducer is equipped with a driving synchronous pulley, and one end of the lead screw is equipped with a driven synchronous pulley. The two are connected by a synchronous belt. A nut that matches the thread of the lead screw is fitted on the lead screw. The outer side of the nut is fixedly connected to the electric push rod. The operation of the motor drives the driving synchronous pulley to rotate, causing the lead screw to rotate. The rotation of the lead screw drives the nut to drive the electric push rod to move linearly.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. Example

[0021] refer to Figure 1 , Figure 2 A heat storage element closure device includes a rectangular frame-type base 1 composed of welded square steel pipes, providing stable foundation support for the entire device and located at the bottom of the device. Four uprights 2, also made of square steel pipes, are installed opposite each other on the base 1 and are firmly connected to the base 1 by welding. They are positioned on the upper sides of the base 1 near the four corners. Two upper support beams 3 are installed on both sides of the upper end of one of the uprights 2 and are fixed to the uprights 2 by welding, clamping the upper ends of the two uprights 2 in the middle. Two upper support beams 3 are also installed on both sides of the uprights 2 on the other side. The cylinder ends of two hydraulic cylinders 4 are welded to the middle of the two upper support beams 3 on each side. Each cylinder end has at least two welding points with each of the two upper support beams 3 on each side to ensure stable and firm force distribution. The piston rod of the hydraulic cylinder 4 faces downward and is welded to the end connecting plate. The end connecting plates on both sides are welded to the two ends of an upper pressure beam 5, which moves linearly with the lifting and lowering action of the piston rod of the hydraulic cylinder 4 to apply pressure to the heat storage element.

[0022] The bottom beam 601 is placed horizontally on the base 1 and welded to it. The push-side column 602 and the baffle column 603 are welded and fixed to both ends of the bottom beam 601, respectively. The bottom beam 601, the push-side column 602, and the baffle column 603 are all square steel pipe structures, and there are two of each. Because the combined shape of the multiple heat storage elements is approximately trapezoidal, the push-side column 602 is set at an obtuse angle with the base 1, and the baffle column 603 is set vertically with an approximately right angle with the base 1, in order to adapt to the shape of the heat storage elements and to distribute the force evenly on the heat storage elements when they are closed.

[0023] The heat storage element is placed between the base 1 and the column 2, or more specifically, in the space formed by the bottom beam 601, the push-side column 602 and the baffle column 603. The push-side column 602 provides support when the lateral pressure applies pressure to the heat storage element, and the baffle column 603 restrains the heat storage element from being pushed out of the device by the lateral pressure.

[0024] refer to Figure 1 , Figure 2 , Figure 3 Two side support beams 7 are horizontally welded to the middle of the two pusher columns 602. A cylinder end of a hydraulic cylinder 8 is welded to the middle of the two side support beams 7. The cylinder end has at least two welding points with the two side support beams 7 to ensure stable and secure force distribution. The piston rod of the hydraulic cylinder 8 faces downwards and is welded to an end connecting plate. A fork-shaped joint seat 901 is welded to the end connecting plate. The fork-shaped joint seat 901 has a through hole and an H-shaped side pressure plate frame 10 made of welded steel pipes in the middle. A fork-shaped receiving seat 902 is welded to the side. This fork-shaped receiving seat 902 has two opposing through holes that mate with the fork-shaped joint seat 901. A pin 903 passes through the through holes in both the fork-shaped joint seat 901 and the fork-shaped receiving seat 902, connecting the side pressure plate frame 10 and the hydraulic cylinder 8 for applying pressure from the side. The pin 903 connection also allows the side pressure plate frame 10 to be angled relative to the hydraulic cylinder 8 around the axis of the pin 903 to adapt to the alignment requirements of the heat storage components under different operating conditions. In this example, the power unit and transmission method of the hydraulic cylinders 4 and 8 are the same; both are powered by a hydraulic pump installed on the ground connected to the cylinders via hydraulic oil pipes. In the cylinder structure used in this equipment, an adjusting bolt is provided at a specific position on the cylinder body. This adjusting bolt is installed by engaging with a corresponding threaded hole on the cylinder body. Its design aims to achieve precise control of the piston rod extension stroke, making it a key component for replacing traditional limit switches to achieve stroke control.

[0025] During equipment operation, when it is necessary to adjust the extension stroke of the hydraulic cylinder piston rod, the operator can use a suitable tool to operate the adjusting bolt. To shorten the piston rod extension stroke, the operator rotates the adjusting bolt clockwise, causing it to penetrate deeper into the cylinder along the threaded hole. As the adjusting bolt is screwed in, its end gradually approaches the movement trajectory of the piston rod. When the piston rod extends and contacts the end of the adjusting bolt, it cannot continue forward, thus shortening the stroke. Conversely, to increase the piston rod extension stroke, the operator rotates the adjusting bolt counterclockwise, causing it to extend outward from the cylinder, increasing the range of motion of the piston rod. This satisfies diverse requirements for the piston rod extension stroke under different operating conditions, achieving precise stroke control without the need for limit switches.

[0026] Working principle: In use, the heat storage element is placed between the base 1 and the column 2 from the top, more specifically, in the space formed by the bottom beam 601, the push side column 602 and the baffle side column 603. The side cylinder 8 is activated to push the side pressure plate frame 10 and, under the constraint of the baffle side column 603, make all the heat storage elements come together. The downward pressure cylinder 4 is activated to apply pressure from top to bottom to the heat storage element. When the pressure and stroke reach the preset values, the connecting ribs are welded to the side of the heat storage element. After the assembly process is completed, the button is activated to retract the downward pressure cylinder 4 and the side pressure cylinder 8, the upper pressure beam 5 is removed, the heat storage element is lifted away, and then the next batch of heat storage elements to be assembled is lifted in. Example

[0027] refer to Figure 4 Based on the first specific implementation method, the hydraulic cylinder 8 is replaced by a side-pressure electric push rod 18. The side-pressure electric push rod 18 is connected to the side-pressure plate frame 10. The power device of the side-pressure electric push rod 18 is a side-pressure motor 11 placed on the side of the side support beam 7. The side-pressure motor 11 is connected to a reducer. The output shaft of the reducer is connected to the active synchronous pulley 12. One end of the lead screw 15 is fixed on the side support beam 7 through the bearing seat 16. The lead screw 15 is provided with a driven synchronous pulley 14. The active synchronous pulley 12 and the driven synchronous pulley 14 are connected by a synchronous belt, which is a belt 13. A nut 17 adapted to the thread is installed on the threaded surface of the lead screw 15. The outer side of the nut 17 is fixedly connected to the side pressure electric push rod 18. After the side pressure motor 11 is started, the mechanical force drives the active synchronous pulley to rotate through the reducer. The belt 13 drives the driven synchronous pulley 14 to rotate and drives the lead screw to rotate. Since the lead screw 15 can only rotate, it drives the nut 17 to push the side pressure electric push rod 18 out, further pushing the side pressure plate frame 10 to apply side pressure to the original part and complete the closing process. When it is necessary to withdraw the side pressure operation, the side pressure motor 11 reverses and drives the lead screw 15 to rotate in the opposite direction, thereby retracting the side pressure electric push rod 18.

[0028] The hydraulic cylinder 4 in the first embodiment can also be replaced by an electric push rod. The structure and transmission method of the electric push rod are the same as those of the side-pressure electric push rod 18, so they will not be described again.

[0029] Other features are the same as in the first embodiment.

[0030] In this embodiment, a servo motor or stepper motor is selected to achieve precise control of the rotational speed and the precise control of the closing and pressing strokes. The synchronous belt drive is clearly shown in the attached drawings, and its working principle and related structure are presented in detail therein.

[0031] It should be noted that the above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
