Description

Technical Field

[0001] This utility model relates to the field of heating infrastructure construction technology, and more specifically to an automatic bending device for butterfly panels. Background Technology

[0002] A thermal storage tank is a device used to store and release thermal energy, and it is widely used in many fields such as heating, industrial waste heat recovery, and solar power generation.

[0003] Thermal storage tanks are typically large, reaching heights of over 37 meters and diameters of over 9 meters, requiring the construction of an installation platform during the installation process.

[0004] In current construction, the installation platform is directly welded to the tank body. After the heat storage tank is installed, the construction platform needs to be dismantled. Due to the welding between the installation platform and the tank body, a lot of cutting and welding work is required during the dismantling process, which can easily cause damage to the tank body.

[0005] In some construction sites, in order to prevent damage to the tank, a large number of butterfly boards are processed into supports for the construction of installation platforms. There is no need to weld them to the tank. Currently, construction companies usually purchase a large number of butterfly boards from outside. After the butterfly board supports are used, they cannot be reused, resulting in material waste.

[0006] Therefore, how to provide a bending device that can process steel plates into butterfly plates without purchasing butterfly plates and reduce construction costs is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, the present invention provides an automatic butterfly plate bending device that can bend steel plates into butterfly plates. By processing the butterfly plates into brackets, the installation platform of the heat storage tank can be erected, which reduces the construction cost and avoids the disadvantages of large workload and damage to the tank caused by welding the installation platform to the tank.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An automatic bending device for butterfly boards includes:

[0010] support

[0011] A hydraulic cylinder, wherein the cylinder body is detachably connected to the upper end of the bracket;

[0012] Support columns, wherein there are multiple support columns, and the lower ends of the multiple support columns are vertically fixed to the top surface of the bracket relative to the hydraulic cylinder in the circumferential direction;

[0013] A movable beam is slidably connected to multiple support columns and its bottom surface abuts against the piston rod of the hydraulic cylinder at the middle; multiple pressure plates are fixed to the top surface of the movable beam.

[0014] A fixed beam is fixed to the top of the multiple support columns and corresponds to the movable beam; a positioning plate is fixed to the bottom surface of the fixed beam, and the positioning plate corresponds to the gap between two adjacent pressure plates.

[0015] The beneficial effect of this utility model is that the steel plate to be bent is placed on the pressure plate, and the movement of the movable beam is controlled by the extension and retraction of the hydraulic cylinder piston rod. When the steel plate contacts the positioning plate, the piston rod continues to extend, and the butterfly plate can be bent by cooperating with the gap between the two adjacent pressure plates.

[0016] Preferably, the bracket includes a top beam, support legs, and a mounting plate; there are multiple top beams connected end-to-end to form a square frame; there are multiple support legs, the upper ends of which are welded to the bottom surface of the square frame; the mounting plate is fixed to the top surface of the square frame; and the support columns are vertically fixed to the mounting plate. The bracket has a simple structure and is easy to manufacture. The top surface of the bracket uses the mounting plate to install the support columns and hydraulic cylinders.

[0017] Preferably, it also includes a cylinder base, which comprises multiple steel plates that are joined together to form a box and fixed to the top surface of the mounting plate; the hydraulic cylinder is located within the inner cavity of the box. Confining the hydraulic cylinder within the box prevents it from shaking or moving due to excessive hydraulic pressure during bending.

[0018] Preferably, it also includes a hydraulic pump and an oil pipe; the side wall of the housing corresponding to the oil inlet of the hydraulic cylinder is provided with a groove; one end of the oil pipe is connected to the oil outlet of the hydraulic pump, and the other end passes through the groove and is connected to the oil inlet to drive the extension and retraction of the piston rod.

[0019] Preferably, there are four support legs, with the upper ends of the four support legs fixed to the four corners of the bottom surface of the square frame, and the lower ends extending outward along the frame of the square frame. The inclined arrangement of the support legs ensures the stability of the support.

[0020] Preferably, a support base is fixed between the multiple outriggers, and the hydraulic pump is mounted on the support base. The hydraulic pump is mounted via the support base, eliminating the need for additional space outside the support frame and resulting in a more compact structure.

[0021] Preferably, there are two support columns, and the two end faces of the movable beam slide against the opposite side walls of the two support columns.

[0022] Preferably, baffles are fixed to both sides of the support column, and the ends of the side walls of the movable beam slide against the panels of the baffles. Since the movable beam is supported only by the piston rod of the hydraulic cylinder, the baffles prevent the movable beam from tilting, ensuring that the bending operation is carried out effectively.

[0023] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an automatic bending device for butterfly panels, which can realize the automatic bending operation of butterfly panels and facilitate the processing of the support for the heat storage tank installation platform.

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.

[0028] like Figure 1As shown in the figure, this utility model embodiment discloses an automatic bending device for butterfly boards, including a bracket 1, a hydraulic cylinder 2, support columns 6, a movable beam 7, and a fixed beam 8; the cylinder body of the hydraulic cylinder 2 is detachably connected to the upper end of the bracket 1. In this embodiment, the cylinder body of the hydraulic cylinder 2 can be directly placed on the top surface of the bracket 1; there are multiple support columns 6, and the lower ends of the multiple support columns 6 are vertically fixed to the top surface of the bracket 1 relative to the circumference of the hydraulic cylinder 2; the movable beam 7 is slidably connected to the multiple support columns 6, and its bottom center is connected to the piston rod of the hydraulic cylinder 2. The movable beam 7 is connected to the support column 6. Multiple pressure plates 71 are fixed on the top surface of the movable beam 7. The piston rod of the hydraulic cylinder 2 drives the movable beam 7 to move up and down along the support column 6. The steel plate to be processed is placed on the pressure plate 71. The fixed beam 8 is fixed to the top of the multiple support columns 6 and corresponds to the movable beam 7. The bottom surface of the fixed beam 8 is fixed with a positioning plate 81, which corresponds to the gap between two adjacent pressure plates 71. During the upward movement of the movable beam 7 along the support column 6, the bending operation of the butterfly plate can be realized under the action of the positioning plate 81 and the pressure plate 71.

[0029] In this embodiment, there are two pressure plates, and the gap between the two pressure plates can accommodate a positioning plate, thereby enabling the steel plate to be bent into a butterfly plate.

[0030] To further optimize the above technical solution, the bracket 1 includes a top beam 12, support legs 11 and mounting plate 14; there are multiple top beams 12, which are connected end to end to form a square frame; there are multiple support legs 11, and the upper ends of the multiple support legs 11 are welded to the bottom surface of the square frame; the mounting plate 14 is fixed to the top surface of the square frame; and the support column 6 is vertically fixed on the mounting plate 14.

[0031] There are four top beams, all made of angle steel. The four angle steels are aligned end-to-end and welded together to form a square frame. The support legs are also made of angle steel. Angle steel is a common support material, readily available and inexpensive. To save costs, the width of the mounting plate can be smaller than the width of the square frame. The bottom ends of the mounting plate are welded and fixed to two oppositely arranged angle steels.

[0032] In some other specific embodiments, to ensure the stability of the hydraulic cylinder, a cylinder seat 3 is also included. The cylinder seat 3 includes multiple steel plates 31, which are arranged to form a box and fixed to the top surface of the mounting plate 14; the hydraulic cylinder 2 is located in the inner cavity of the box.

[0033] The box structure is made of four steel plates welded together. The lower end is welded and fixed to the mounting plate, and the upper end is open. The hydraulic cylinder is placed in the inner cavity of the box, and the circumference of the hydraulic cylinder abuts against the inner wall of the box. The cylinder seat restricts the hydraulic cylinder from shaking or moving.

[0036] In some other embodiments, in order to ensure the compactness of the device, a support base 13 is fixed between multiple legs 11, and the hydraulic pump 4 is mounted on the support base 13.

[0037] To further optimize the above technical solution, two support columns 6 are used, and the two end faces of the movable beam 7 slide against the opposite side walls of the two support columns 6. The movable beam 7 is located between the two support columns 6, and is driven by the hydraulic cylinder 2 to move up and down relative to the support columns 6.

[0038] The supporting columns, movable beams, and fixed beams are all made of square steel, which ensures structural strength and is easy to source, resulting in low cost.

[0039] To further optimize the above technical solution, baffles 9 are fixed to both sides of the support column 6, and the ends of the side walls of the movable beam 7 slide against the panels of the baffles 9. By setting the baffles 9, the movable beam 7 can be prevented from sliding out of the two support columns 6.
