Description

Technical Field

[0001] The present invention relates to the technical field of maglev track technology, and particularly to a demolding device for the side mold of a suspension groove of a maglev track beam. Background Art

[0002] The track beam is an important part 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 magnetic buoyancy. In order to ensure the stable development of lift and resistance when the vehicle takes off and lands, and at the same time ensure the driving comfort of the vehicle in the middle section of the line, very strict requirements are put forward for the construction accuracy of the traditional maglev track beam, resulting in the difficulty for the traditional in-situ casting construction process to meet such accuracy requirements.

[0003] In the prior art, the applicant of this case first proposed a brand-new maglev track beam structure and applied for patents such as "Track Beam Structure and Its Forming Method for Ultra-High-Speed Maglev Track Test Section" and "An Assembled Maglev Track Beam" earlier; in such prior art, the idea of pre-burying sleeves during the on-site pouring process was proposed to facilitate the connection of subsequent magnet modules.

[0004] With the continuous in-depth research, the applicant found that since the lateral width of the suspension groove of this type of new track beam is only 40 - 50 cm, the distance between the two side mold templates is relatively narrow; and the volume of the concrete component to be cast and formed is large. Therefore, according to the traditional template setting idea, relatively thick side mold templates are required; if the thickness of the single-side template increases by 5 cm, the width of the working space will be reduced by a total of 10 cm, which undoubtedly exacerbates the operation difficulty. To overcome the above deficiencies, the applicant proposed a technical idea of setting a number of backing ribs on the outer wall of the side mold template to reinforce the side mold template, and submitted a patent application on the same day as this application. Through the setting of the backing ribs, the side mold template can use a relatively thin thickness and is only relatively thicker at the backing ribs, avoiding the significant increase in operation difficulty caused by the overall excessive thickness of the template. However, after setting the backing ribs, the demolding difficulty of the side mold template increases accordingly; during the process of hoisting and removing the side mold template after demolding, the lifted backing ribs swing left and right, easily causing a large number of knocks with the backing ribs on the other side and even getting stuck with each other, making it difficult to remove the template. Summary of the Invention

[0005] The present invention provides a demolding device for the side mold of a suspension groove of a maglev track beam 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 knocks and jams, and achieve the purpose of reducing the demolding difficulty of 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] Further, the positioning mechanism includes first strip-shaped grooves formed on opposite sides of the column surface, and the long axis of the first strip-shaped groove is parallel to the pushing direction of the pushing mechanism; the positioning mechanism further includes a suspension plate connected in the first strip-shaped groove, and the top end of the suspension plate is hinged in the first strip-shaped groove through a folding hinge.

[0013] When the device is not in use, the suspension plate is stored in the corresponding first strip-shaped groove. When the positioning mechanism is needed for positioning, first lift the column above the inspection hole so that the suspension plates on both sides can open above the inspection hole, and then lower the column so that the suspension plates on both sides are respectively placed on the top surfaces of the bottom plates on opposite sides of the top of the inspection hole; since the suspension plate is hinged by a folding hinge and cannot continue to open when opened to a specified angle, the stability of the temporary suspension and positioning of the column can be ensured.

[0014] Further, the positioning mechanism further includes a second strip-shaped groove formed on the column surface and a limit post connected in the second strip-shaped groove, and the top end of the limit post is hinged in the second strip-shaped groove.

[0015] When the device is not in use, the limit post is stored in the second strip-shaped groove. After the suspension plate is suspended, the limit post is also rotated out in this solution so that the end of the limit post away from the hinged position with the second strip-shaped groove abuts against the hole wall of the inspection hole, thereby providing lateral limitation to the column. At the same time, the friction force between the limit post and the groove wall is utilized to improve the stability of the device.

[0016] Further, a groove is formed at the bottom end of the limit post, and a friction block is slidably fitted in the groove. The friction block is connected to the bottom of the groove through a plurality of elastic members. In order to avoid interference during the process of the limit post rotating to abut against the hole wall and at the same time improve the adaptability of the limit post to different size errors of the inspection hole, the bottom end of the limit post is set as a floating structure in this solution. Through a plurality of elastic members, the friction block can float along the axial direction of the limit post, which is beneficial to the limit post rotating to a state where its axis is perpendicular to the hole wall and it will not be unable to rotate in place due to the obstruction of the hole wall during the rotation process.

[0017] In addition, for the limit post rotated to a state perpendicular to the groove wall, the elastic members inside it are in a compressed state, which can push the friction block, so that there is a large pressure between the friction block and the hole wall, and thus the friction force between the two is large, which is more beneficial to improving the stability of the limit post abutting against the hole wall; at the same time, for inspection holes with different size errors, the limit post of this solution also has stronger adaptability.

[0018] Further, the limiting post is a telescopic post, which has stronger versatility for inspection holes of different sizes; its telescopic method can adopt any existing telescopic method, such as two sleeved tubes connected by threads, etc. A plurality of convex teeth and / or concave teeth are arranged on one side surface of the friction block away from the direction where the groove is located, so as to increase the surface roughness of the friction block, and further increase the friction coefficient between the friction block and the hole wall.

[0019] Further, a push block is rotatably connected to the top end of the pushing mechanism, an extension rod is detachably connected to the push block, the axis of the extension rod is perpendicular to the pushing direction of the pushing mechanism, and the rotation axis of the push block is collinear with the axis of the pushing mechanism.

[0020] Under certain working conditions, there may be no back ribs directly opposite above the inspection hole, or the back rib to be pushed is not directly above the hole wall of the inspection hole. At this time, it is difficult for the top end of the pushing mechanism to directly abut against the lower part of the back rib, which is not convenient for the required pushing operation. Based on this, in this solution, a push block is rotatably connected to the top end of the pushing mechanism, and an extension rod is detachably connected to the push block. The extending direction of the extension rod is adjusted by rotating the push block, and the extension rod extends to the lower part of the back rib, so that the pushing control range of the pushing mechanism can be significantly expanded, and the versatility of the present application can be significantly increased and the applicable range can be expanded.

[0021] Further, a threaded through hole is formed in the push 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 detachably connected to the push block by means of screw thread cooperation through the threaded through hole, which can avoid automatic sliding along the axis, ensure the installation stability of the connecting rod, and further improve the bearing stability of the back rib and the side formwork.

[0023] Further, the extension rod includes a threaded section and a smooth rod section, and the threaded section is matched with the threaded through hole. In this solution, the threaded section of the extension rod is directly connected to the threaded through hole, and the smooth rod section is located directly below the back rib.

[0024] Further, considering that the connecting rod with a threaded section and a smooth rod section structure has a fixed connection position with the threaded through hole, that is, the position of the smooth rod section relative to the push block is also fixed, there will inevitably be problems of insufficient adaptability and difficulty for the smooth rod section to extend to the lower part of the back rib. Based on this, a preferred technical solution is also proposed for the extension rod. The extension rod is integrally a screw rod, and further includes a first threaded sleeve and a second threaded sleeve that are matched with the screw rod; an external thread matched with the threaded through hole is arranged on the outer wall of the first threaded sleeve; 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, as a bearing component, is adjusted below the backing strip, and its smooth outer wall is used for bearing to avoid serious damage to the formwork backing strip caused by the existence of threads. 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, enabling this application to be applicable to the combined use of backing strips and inspection holes in more different relative position relationships, significantly improving the versatility of this application.

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

[0027] 1. The demoulding device for the floating trough side formwork of the maglev track beam of the present invention makes full use of the inspection holes on the bottom floor of the high-speed maglev track beam, enabling the bottom of the side formwork to always be stressed, with part of the gravity always loaded on the top of the column body, thereby reducing the probability and amplitude of lateral shaking of the side formwork, reducing the risk of collision between the lifted side formwork and the opposite side formwork or the concrete trough wall, and also reducing the risk of jamming between the opposite side formworks due to the existence of the backing strip, which is beneficial to quickly and conveniently complete the demoulding and removal of the side formwork for forming the floating trough wall.

[0028] 2. In the demoulding device for the floating trough side formwork of the maglev track beam of the present invention, the bottom end of the limit post is set as a floating structure, and through a number of elastic members, the friction block can float along the axial direction of the limit post, which is beneficial to rotating the limit post to a state where its axis is perpendicular to the hole wall, and it will not be unable to rotate in place due to the obstruction of the hole wall during the rotation process; for inspection holes with different dimensional errors, the limit posts of this solution also have stronger adaptability.

[0029] 3. In the demoulding device for the floating trough side formwork of the maglev track beam of the present invention, by extending the extension rod below the backing strip, the pushing control range of the pushing mechanism can be significantly expanded, significantly increasing the versatility of this application and expanding the scope of application.

In the demoulding device for the floating trough side formwork of the maglev track beam of the present invention, the positions of the first threaded sleeve and the second threaded sleeve on the extension rod can be flexibly adjusted according to specific working conditions, enabling this application to be applicable to the combined use of backing strips and inspection holes in more different relative position relationships, significantly improving the versatility of this application.

On one side surface of the positioning block 18 facing the mouth direction of the positioning cylinder 17, a pushing inclined surface 26 matching the reduced-diameter portion 25 is provided. The pushing inclined surface 26 is inclined gradually from the outside to the inside along the radial direction towards the bottom of the positioning cylinder 17.

[0095] The outer wall of the positioning cylinder 17 is provided with an external thread; the inner wall of the pin cap 27 is provided with an internal thread matching the external thread; and a nut 28 matching the positioning cylinder 17 is further included.

[0096] In this embodiment, the cross-section of the pin cap 27 is concave-shaped, and the open end faces the direction where the reduced-diameter portion 25 is located; and along the radial direction, the annular space gap between the pin cap 27 and the starting pin 24 matches the wall thickness of the positioning cylinder 17. When the outer end of the positioning cylinder 17 abuts against the outer end of the pin cap 27, the end of the reduced-diameter portion 25 just abuts against the mounting block 21, and at this time, each positioning block 18 slides radially outwards to the maximum stroke.

[0097] A plurality of back ribs 29 are provided on the outer wall of the side mold template 1. Assembly grooves 30 are formed on the surface of the back ribs 29. Two opposite bearing seats 31 are slidably fitted in the assembly grooves 30. A rotating shaft 33 is rotatably connected between the two bearing seats 31 through a bearing 32. A roller 34 is fixedly sleeved on the rotating shaft 33. The sliding direction of the bearing seats 31 is perpendicular to the outer wall of the side mold template 1. A compression spring 35 is connected between the bearing seats 31 and the bottom of the assembly grooves 30. In the natural state, a part of the roller 34 is located outside the assembly grooves 30.

[0098] The back ribs 29 in this embodiment can be arranged horizontally and / or vertically. At least one assembly groove 30 and its internal structure are provided on each back rib 29.

[0099] The side mold structure of this embodiment has the following advantages:

[0100] The purpose of synchronously completing the construction of the anchor plate and the sleeve during the forming process of the suspension tank is achieved, and the problem of difficult later installation of the anchor plate due to the too narrow horizontal space inside the suspension tank is solved; the sleeve can be installed after the side formwork and the anchor plate are installed, thereby avoiding the problem that the sleeve is easily damaged by collision due to the limited working space when the side formwork is positioned after the sleeve is installed in advance; the temporary positioning of the sleeve can be realized, the sleeve falling off is avoided, and the use safety and the stability of the sleeve consolidation are significantly improved; it can ensure that the anchor plate cannot fall off automatically, the stable temporary connection of the anchor plate is realized, and the connection structure of the anchor plate operates from the outside of the side formwork and is located inside the anchor plate, which will not interfere with the consolidation between the anchor plate and the concrete, and effectively realizes the temporary connection of the anchor plate in a narrow space, significantly improving the construction convenience; after the starting mechanism is taken out, each positioning block can automatically contract and reset, which is convenient for removing the formwork after the concrete has set; after the starting mechanism is inserted, each positioning block can clamp the starting mechanism, which is beneficial to maintaining the stable position of the starting mechanism; the side formwork is reinforced by the backing strip, so that the side formwork can use a relatively thin thickness and is only relatively thicker at the backing strip, thereby avoiding the problem that the overall thickness of the formwork is too thick and the operation difficulty is significantly increased; the risk of collision damage to the side formwork and the wall of the formed suspension tank can be reduced, and the side formwork can also be guided, which is more conducive to quickly removing the side formwork after demoulding.
