Description

Technical Field

[0001] The invention relates to the technical field of magnetic levitation tracks, and in particular to a levitation groove side mold demoulding device for a magnetic levitation track beam. Background Art

[0002] The track beam is an important component of the maglev track. In the field of high-speed maglev, the distance between the train magnet and the magnet on the track beam directly affects the change of the magnetic buoyancy force. In order to ensure the smooth development of lift and resistance of the vehicle when taking off and landing, and to ensure the riding comfort of the vehicle in the middle section of the line, very strict requirements are placed on the construction accuracy of traditional maglev track beams, which makes it difficult for traditional cast-in-place construction technology to meet this accuracy requirement.

[0003] In the prior art, the applicant in this case was the first to propose a new maglev track beam structure, and previously applied for patents such as "track beam structure and forming method for ultra-high-speed maglev track test section" and "an assembled maglev track beam"; in this type of prior art, the idea of ​​pre-embedded sleeves during on-site casting was proposed to facilitate the connection of subsequent magnet modules.

[0004] As the research deepened, the applicant found that since the lateral width of this type of new type of track beam suspension groove is only 40 to 50 cm, the spacing between the side formwork templates on both sides is relatively narrow; and the volume of the concrete component to be cast is large, so if the traditional template setting idea is followed, a thicker side formwork template is required; if the thickness of the single-side template is increased by 5 cm, the width of the working space will be reduced by 10 cm, which undoubtedly aggravates the difficulty of the operation. In order to overcome the above shortcomings, the applicant proposed a technical idea of ​​setting a number of back ribs on the outer wall of the side formwork template and reinforcing the side formwork template through the back ribs, and submitted a patent application on the same day as this application. Through the setting of the back ribs, the side formwork template can use a relatively thin thickness and only be relatively thicker at the back ribs, avoiding the overall thickness of the template from significantly increasing the difficulty of the operation. However, after the back ribs are set, the demoulding difficulty of the side formwork template increases; in the process of hoisting and removing the side formwork template after demoulding, the lifted back ribs swing left and right, which is easy to cause a large number of collisions with the back ribs on the other side, and even jamming with each other, making it more difficult to remove the template. Summary of the invention

[0005] The present invention provides a demoulding device for the side mold of the suspension groove of the maglev track beam, so as to solve the problem that the side mold template of the suspension groove of the maglev track beam is difficult to remove and is prone to collision and jamming, thereby achieving the purpose of reducing the difficulty of removing the side mold template of the suspension groove of the maglev track beam.

[0006] The present invention is achieved through the following technical solutions:

[0007] A demoulding device for the side mold of a suspended groove of a maglev track beam comprises a column, a pushing mechanism arranged in the column, the pushing end of the pushing mechanism faces upward and passes through the top of the column; and a positioning mechanism arranged on the column, the positioning mechanism is used to position the column on the wall of a maintenance hole of the maglev track beam.

[0008] In view of the problem that the side mold template of the suspension groove of the maglev track beam is difficult to remove and prone to collision and jamming, the present invention proposes a side mold demoulding device for the suspension groove of the maglev track beam, wherein the interior of the column is a hollow structure capable of accommodating a push mechanism, and the top of the hollow structure is open, so that the push end of the push mechanism can pass through the top of the column. The positioning mechanism can use any positioning method that can be implemented by a person skilled in the art to position the column on the wall of the inspection hole of the maglev track beam.

[0009] The present application makes full use of the inspection hole on the bottom plate of the high-speed maglev track beam. In the process of casting the track beam in sections, the bottom plate and the inspection hole thereon have been pre-constructed, and then the side formwork is installed on the bottom plate and the suspension groove is cast; when the solidification is completed and the formwork needs to be removed, the device is carried from the inspection hole into the space between the two side formworks of the suspension groove wall, and then the column is positioned on the inspection hole wall of the maglev track beam through the positioning mechanism, and then the pushing mechanism is started to make the pushing mechanism abut against the bottom of the back rib on the surface of the side formwork, and after the side formwork is removed, the side formwork is lifted by a crane. During the process of lifting the formwork template upward out of the suspended trough, the jacking mechanism below is lifted synchronously, so that the side formwork template during the lifting process is subjected to a thrust from bottom to top, which can make the bottom of the side formwork template always under force, and part of the gravity is always loaded on the top of the column, thereby reducing the probability and amplitude of lateral shaking of the side formwork template, reducing the risk of collision between the lifted side formwork template and the opposite side formwork or concrete trough wall, and reducing the risk of jamming between the opposite side formwork templates due to the existence of back ribs, which is conducive to the quick and convenient demoulding and removal of the side formwork template used for forming the trough wall of the suspended trough.

[0010] The pushing mechanism in the present application can be implemented by any linear drive device with lifting and pushing functions in the prior art, such as a cylinder, a hydraulic cylinder, an electric push rod, a lifting rod or a lifting platform.

[0011] Furthermore, the column has a cavity formed at the top, and the cavity is used to receive the push mechanism. When the device is not needed, the push mechanism is received in the cavity, which is beneficial to protecting the push mechanism and convenient for the applicant to enter the space between the templates on both sides of the wall of the suspension tank through the inspection hole.

[0012] Furthermore, the positioning mechanism includes a first strip groove opened on opposite sides of the column surface, and the long axis of the first strip groove is parallel to the pushing direction of the pushing mechanism; the positioning mechanism also includes a hanging plate connected to the first strip groove, and the top end of the hanging plate is hinged in the first strip groove through a folding hinge.

[0013] When the device is not needed, the hanging plate is stored in the corresponding first strip groove. When the positioning mechanism is needed for positioning, first lift the column to the top of the inspection hole so that the hanging plates on both sides can be opened to the top of the inspection hole, and then lower the column so that the hanging plates on both sides are respectively placed on the top surface of the bottom plate on the opposite sides of the top of the inspection hole; because the hanging plates are hinged by folding hinges and cannot be opened further after being opened to a specified angle, the stability of the temporary hanging positioning of the column can be guaranteed.

[0014] Furthermore, the positioning mechanism also includes a second strip groove opened on the surface of the column, a limiting column connected to the second strip groove, and the top end of the limiting column is hinged in the second strip groove.

[0015] When the device is not in use, the limiting column is stored in the second strip groove. When the hanging plate is hung, the limiting column is rotated out so that the limiting column is away from the end of the hinged position with the second strip groove and abuts against the wall of the inspection hole, thereby limiting the column body horizontally and utilizing the friction between the limiting column and the groove wall to improve the stability of the device.

[0016] Furthermore, a groove is provided at the bottom end of the limit column, and a friction block is slidably fitted in the groove, and the friction block is connected to the bottom of the groove through a number of elastic parts. In order to avoid interference during the process of the limit column rotating to abut against the hole wall and to improve the adaptability of the limit column to different inspection hole size errors, the present solution sets the bottom end of the limit column as a floating structure, and enables the friction block to float along the axis of the limit column through a number of elastic parts, which is conducive to rotating the limit column to a state where the axis is perpendicular to the hole wall, and the limit column will not be unable to rotate into place due to obstruction of the hole wall during the rotation process.

[0017] In addition, when the limit column is rotated to a state perpendicular to the groove wall, the elastic part inside it is in a compressed state, which can push the friction block, so that there is a greater pressure between the friction block and the hole wall, and then the friction between the two is greater, which is more conducive to improving the stability of the limit column against the hole wall; at the same time, for inspection holes with different dimensional errors, the limit column of this scheme also has stronger adaptability.

[0018] Furthermore, the limit column is a telescopic column, which can be more versatile for inspection holes of different sizes; its telescopic method can adopt any existing telescopic method, such as two threaded sleeves, etc. A plurality of convex teeth and / or concave teeth are arranged on the surface of the friction block away from the groove to increase the surface roughness of the friction block, thereby increasing the friction coefficient between the friction block and the hole wall.

[0019] Furthermore, the top end of the pushing mechanism is rotatably connected to a pushing block, and the pushing block is detachably connected to an extension rod, the axis of the extension rod is perpendicular to the pushing direction of the pushing mechanism, and the rotating shaft of the pushing block is colinear with the axis of the pushing mechanism.

[0020] Under certain working conditions, there may not be any back rib directly above the inspection hole, or the back rib to be pushed is not directly above the wall of the inspection hole. At this time, it is difficult for the top of the push mechanism to directly contact the bottom of the back rib, which is not convenient for the required pushing operation. Based on this, the top of the push mechanism is rotatably connected to the push block, and an extension rod is detachably connected to the push block. The extension direction of the extension rod is adjusted by rotating the push block, and the extension rod is extended to the bottom of the back rib, thereby significantly expanding the push control range of the push mechanism, significantly increasing the versatility of the present application and expanding the scope of application.

[0021] Furthermore, a threaded through hole is provided on the pushing block, and the axis of the threaded through hole is perpendicular to the pushing direction of the pushing mechanism; the threaded through hole is used to connect the extension rod.

[0022] In this solution, the connecting rod is connected to the push block in a detachable manner through a threaded through hole, which can avoid automatic sliding along the axial direction, ensure the installation stability of the connecting rod, and further improve the bearing stability of the back rib and side mold templates.

[0023] Further, the extension rod comprises a threaded section and a polished rod section, and the threaded section matches the threaded through hole. In this solution, the threaded section of the extension rod is directly connected to the threaded through hole, and the polished rod section is located directly below the back rib.

[0024] Furthermore, considering that the connecting rod adopts the structure of threaded section and polished rod section, the connection position and fixation between the connecting rod and the threaded through hole, that is, the position of the polished rod section relative to the push block is also fixed, it is inevitable that there will be problems of insufficient adaptability and difficulty in extending the polished rod section to the bottom of the back rib. Based on this, an optimal technical solution is also proposed for the extension rod, wherein the extension rod is made of a screw rod as a whole, and also includes a first threaded sleeve and a second threaded sleeve matching the screw rod; the outer wall of the first threaded sleeve is provided with an external thread matching the threaded through hole; and the outer wall of the second threaded sleeve is smooth.

[0025] In this solution, both the first threaded sleeve and the second threaded sleeve can be movably sleeved outside the extension rod, the first threaded sleeve is used to connect with the threaded through hole, and the second threaded sleeve is used as a bearing component, which is adjusted to the bottom of the back rib, and is supported by its smooth outer wall to avoid the existence of the thread causing serious damage to the back rib of the template. In this solution, the positions of the first threaded sleeve and the second threaded sleeve on the extension rod can be flexibly adjusted, so they can be flexibly adjusted according to specific working conditions, so that the application can be applied to the coordinated use of back ribs and inspection holes in more different relative position relationships, which significantly improves the versatility of the application.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0027] 1. The demoulding device for the suspended groove side form of the maglev track beam of the present invention makes full use of the inspection hole on the bottom plate of the high-speed maglev track beam, so that the bottom of the side form template is always under force, and part of the gravity is always loaded on the top of the column, thereby reducing the probability and amplitude of lateral shaking of the side form template, reducing the risk of collision between the hoisted side form template and the opposite side form template or the concrete groove wall, and also reducing the risk of jamming between the opposite side form templates due to the existence of back ribs, which is conducive to quickly and conveniently completing the demoulding and removal of the side form template used for forming the groove wall of the suspended groove.

[0028] 2. The present invention is used for the demoulding device of the side mold of the suspended groove of the maglev track beam. The bottom end of the limit column is arranged as a floating structure. Through a plurality of elastic parts, the friction block can float along the axial direction of the limit column, which is conducive to the rotation of the limit column to a state where the axis is perpendicular to the hole wall, and the limit column will not be unable to rotate into place due to obstruction of the hole wall during the rotation process; for inspection holes with different size errors, the limit column of this scheme also has stronger adaptability.

[0029] 3. The demoulding device for the side mold of the suspended groove of the maglev track beam of the present invention can significantly expand the pushing control range of the pushing mechanism by extending the extension rod to the bottom of the back rib, significantly increasing the versatility of the present application and expanding the scope of application.

[0030] 4. The demoulding device for the side mold of the suspended groove of the maglev track beam of the present invention can flexibly adjust the positions of the first threaded sleeve and the second threaded sleeve on the extension rod according to specific working conditions, so that the present application can be applied to the coordinated use of back ribs and inspection holes in more different relative position relationships, which significantly improves the versatility of the present application.
