Description

Technical Field

[0001] The invention belongs to the technical field of tunnel construction related equipment, and designs a multi-joint double-pipeline template cleaning and oiling loop. Background Art

[0002] Now, with the continuous acceleration of urbanization and the popularization of transportation, various high-speed rail tunnels, subway tunnels and highway tunnels need to be built every year. During the construction of the tunnel secondary lining, the template of the template trolley needs to be cleaned and coated with a release agent in the narrow space between the tunnel secondary lining template and the tunnel outline in order to carry out the subsequent secondary lining construction.

[0003] At present, in the construction of the secondary lining of the tunnel, the work of cleaning the secondary lining formwork trolley formwork and applying the release agent is mostly done manually with a brush, which is time-consuming, labor-intensive and inefficient. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-joint dual-pipeline template cleaning and oiling loop in view of the deficiencies in the prior art, which can be used to clean the template of the tunnel secondary lining template trolley and apply a release agent.

[0005] The present invention is achieved through the following technical solutions:

[0006] A multi-joint dual-pipe template cleaning and oiling loop, comprising a template cleaning loop and a template oiling loop, the template cleaning loop and the template oiling loop are arranged parallel to each other, the template cleaning loop is used to clean the template surface, and the template oiling loop is used to apply a release agent to the template surface;

[0007] The template cleaning loop includes multiple sections of sub-template cleaning pipes, all of which are arranged in a semicircular shape along the tunnel cross section; two adjacent sections of sub-template cleaning pipes are connected by a hinge structure, and a limiting component is provided to limit the angle between the two adjacent sections of sub-template cleaning pipes;

[0008] The template oiling loop includes multiple sections of sub-template oiling pipes, all of which are arranged in a semicircle along the tunnel cross section; two adjacent sections of sub-template oiling pipes are connected by a hinge structure, and a limiting component is provided to limit the angle between the two adjacent sections of sub-template oiling pipes;

[0009] Rollers are installed on each section of the sub-template cleaning tube and the sub-template oiling tube, and the template cleaning loop and the template oiling loop are rolled together on the outer surface of the trolley template through the rollers.

[0010] In the above technical solution, the single-section sub-template cleaning tube has a certain curvature, is formed by bending a seamless tube, and is covered with an outer-wound steel wire roller brush.

[0011] In the above technical scheme, a connecting plate is welded to the end of each section of the sub-template cleaning pipe, the end connecting plates of two adjacent sections of the sub-template cleaning pipe are hinged, and an adjusting bolt is installed through the end connecting plates of the two adjacent sections of the sub-template cleaning pipe. The adjusting bolt is used to limit the angle between the two adjacent sections of the sub-template cleaning pipes, so that the angle between the two adjacent sections of the sub-template cleaning pipes can be changed within a certain range. This can ensure that the entire template cleaning loop can autonomously fit the template contour and adapt to different cross-sectional sizes, and can also keep the entire template cleaning loop in a basic annular shape when the template cleaning loop is separated from the template.

[0012] In the above technical solution, the single-section sub-template oiling tube has a certain curvature, is formed by bending a seamless tube, and is wrapped with a sponge on the outside; the template oiling loop is also provided with an oil pipe, which is arranged along the template oiling loop and is embedded in the sponge of each section of the sub-template oiling tube. The oil pipe is connected to the oil supply system, and a plurality of oil outlet holes are opened on the oil pipe, through which the external sponge is filled with oil. In addition, the oil pipe needs to adopt a deformable hose so that the oil pipe can be deformed between two adjacent sections of the sub-template oiling tubes to adapt to the angle changes between the joints of the sub-template oiling tubes.

[0013] In the above technical scheme, a connecting plate is welded to the end of each section of the sub-template oiling tube, the end connecting plates of two adjacent sections of the sub-template oiling tube are hinged, and an adjusting bolt is installed through the end connecting plates of the two adjacent sections of the sub-template oiling tube. The adjusting bolt is used to limit the angle between the two adjacent sections of the sub-template oiling tube, so that the angle between the two adjacent sections of the sub-template oiling tube can be changed within a certain range. This can ensure that the entire template oiling loop can autonomously fit the template contour and adapt to different cross-sectional sizes, and can also ensure that the entire template oiling loop maintains a basic annular shape when the template oiling loop is detached from the template.

[0014] In the above technical solution, permanent magnets are also installed on each section of the sub-template cleaning tube and the sub-template oiling tube, and the template cleaning loop and the template oiling loop can be attached when close to the template through these permanent magnets, and it can be ensured that the template cleaning loop and the template oiling loop can be easily detached when they are separated from the template through the lifting drive unit. Further, the installation structure of the permanent magnet is: the permanent magnet is installed on the installation plate through the bolt and nut assembly, the installation plate is welded to the sub-template cleaning tube and the sub-template oiling tube, and the position of the magnet can be adjusted by the nut, thereby adjusting the suction force on the template.

[0015] The advantages and beneficial effects of the present invention are:

[0016] The multi-joint dual-pipeline template cleaning and oiling loop of the present invention adopts a multi-joint hinged structural design, which can not only ensure that the entire template cleaning loop can autonomously fit the template contour and adapt to different cross-sectional sizes, but also enable the entire template cleaning loop to maintain a basic annular shape when the template cleaning loop is separated from the template.

[0017] The multi-joint dual-pipeline template cleaning and oiling loop of the present invention comprises a template cleaning loop and a template oiling loop, and can be used to clean the template of the tunnel secondary lining template trolley and apply a release agent.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0034] Embodiment 1

[0035] See attached Figure 1-6 A multi-joint dual-pipe template cleaning and oiling loop 2 includes a template cleaning loop 2-1 and a template oiling loop 2-2. The template cleaning loop and the template oiling loop are arranged parallel to each other. The template cleaning loop is used to clean the template surface, and the template oiling loop is used to apply a release agent to the template surface.

[0036] The template cleaning loop 2-1 includes multiple sections of sub-template cleaning pipes 2-11, all of which are arranged in a semicircular shape along the tunnel cross section; the single-section sub-template cleaning pipe has a certain curvature and is formed by bending a seamless pipe, and is covered with an outer-wound steel wire roller brush on the outside, and the steel wire roller brush is used to scrape and clean the template; two adjacent sections of the sub-template cleaning pipes are connected by a hinge structure, and a limiting component is provided to limit the angle between the two adjacent sections of the sub-template cleaning pipes. Specifically, a connecting plate a is welded to the end of each section of the sub-template cleaning pipe. The end connecting plates of two adjacent sections of sub-template cleaning pipes are hinged, and an adjusting bolt b is installed between the end connecting plates of the two adjacent sections of sub-template cleaning pipes. The adjusting bolt is used to limit the angle between the two adjacent sections of sub-template cleaning pipes, so that the angle between the two adjacent sections of sub-template cleaning pipes can be changed within a certain range. This can ensure that the entire template cleaning loop can autonomously fit the template contour and adapt to different cross-sectional sizes, and can also keep the entire template cleaning loop in a basic annular shape when the template cleaning loop is separated from the template.

[0037] The template oiling loop 2-2 includes a plurality of sub-template oiling pipes 2-21, all of which are arranged in a semicircle along the tunnel cross section; the single-section sub-template oiling pipe has a certain curvature, is formed by bending a seamless pipe, and is wrapped with a sponge on the outside; two adjacent sub-template oiling pipes are connected by a hinge structure, and have a limiting component to limit the angle between the two adjacent sub-template oiling pipes. Specifically, a connecting plate a is welded to the end of each sub-template oiling pipe, and the end connecting plates of the two adjacent sub-template oiling pipes are hinged, and an adjusting bolt b is installed through the end connecting plates of the two adjacent sub-template oiling pipes, and the angle between the two adjacent sub-template oiling pipes is limited by the adjusting bolt, so that the angle between the two adjacent sub-template oiling pipes is The angle can vary within a certain range, which can ensure that the entire template oiling loop can autonomously fit the template contour and adapt to different cross-sectional sizes, and can also keep the entire template oiling loop in a basic annular shape when the template oiling loop is detached from the template; further, the entire template oiling loop 2-2 is also provided with an oil pipe s, which is arranged along the template oiling loop 2-2 and embedded in the sponge of each section of the sub-template oiling tube 2-21. The oil pipe is connected to the oil supply system and has a plurality of oil outlet holes on the oil pipe. The external sponge is filled with oil (release agent) through the oil outlet holes. In addition, the oil pipe needs to adopt a deformable hose (such as a rubber hose, a plastic hose, etc.) so that the oil pipe can be deformed between two adjacent sections of the sub-template oiling tubes to adapt to the angle changes between the joints of the sub-template oiling tubes.

[0038] Furthermore, a roller c is installed on each section of the sub-template cleaning tube and the sub-template oiling tube (the roller c is installed between two vertical plates, and the two vertical plates are fixed on the sub-template cleaning tube and the sub-template oiling tube). The roller makes the template cleaning loop and the template oiling loop roll together on the outer surface of the trolley template.

[0039] Furthermore, permanent magnets d are installed on each section of the sub-template cleaning tube and the sub-template oiling tube, and the template cleaning loop and the template oiling loop can be attached when close to the template through these permanent magnets, and can ensure that the template cleaning loop and the template oiling loop can be easily detached when they are detached from the template through the lifting drive unit. Specifically, the installation structure of the permanent magnet is: the permanent magnet d is installed on the installation plate through the bolt and nut assembly, and the installation plate is welded to the sub-template cleaning tube and the sub-template oiling tube. The position of the magnet can be adjusted by the nut, thereby adjusting the suction force on the template.

[0040] Embodiment 2

[0041] See attached Figure 7-10 This embodiment provides a tunnel secondary lining formwork cleaning and release agent application device that adopts the multi-joint dual-pipeline formwork cleaning and oiling loop 2 described in embodiment one, and the device includes a trolley 1, the multi-joint dual-pipeline formwork cleaning and oiling loop 2 described in embodiment one, a formwork cleaning and oiling track 3, a formwork cleaning and oiling walking drive 4, a push rod 5, a formwork cleaning and oiling track lifting drive mechanism, and a cantilever support frame 7.

[0042] The multi-joint dual-pipeline template cleaning and oiling loop 2 is connected to the template cleaning and oiling walking driver 4 through a push rod 5. The template cleaning and oiling walking driver is installed on the template cleaning and oiling track 3. The template cleaning and oiling walking driver can actively walk along the template cleaning and oiling track, thereby realizing the promotion of the multi-joint dual-pipeline template cleaning and oiling loop 2 to move.

[0043] The template cleaning and oiling track is installed on the cantilever support frame 7 through the template cleaning and oiling track lifting and driving mechanism. The cantilever support frame 7 is horizontally fixedly installed at the tail of the trolley. The template cleaning and oiling track lifting and driving mechanism can drive the template cleaning and oiling track to move up and down and adjust its height position. Further, the template cleaning and oiling track lifting and driving mechanism includes three lifting and driving actuators 6, which are respectively located at the front and rear ends and the middle position of the template cleaning and oiling track. The three lifting and driving actuators synchronously lift and move to drive the template cleaning and oiling track to lift and lower. Further, the template cleaning and oiling track includes two parallel tracks, and a plurality of connecting beams are arranged between the two tracks. The lifting and driving actuator is installed at the bottom of the connecting beam.

[0044] The working principle of the tunnel secondary lining formwork cleaning and release agent application device is as follows:

[0045] The template cleaning and oiling loop is initially located below the template on the rear side of the trolley (i.e. Fig.10 m position), which will not affect the normal operation of the template. When the template is demoulding state, the second lining template trolley is a certain distance away from the tunnel contour. When it is necessary to start the cleaning and oiling work of the template, the template cleaning and oiling loop is switched from the initial position to the working position. The specific method is: control the template cleaning and oiling track lifting drive mechanism (the three lifting drive actuators move upward synchronously), drive the template cleaning and oiling track to move upward as a whole, and then the template cleaning and oiling walking driver 4 on the template cleaning and oiling track drives the push rod 5 and the template cleaning and oiling loop 2 to rise. When the template cleaning and oiling loop 2 is higher than the top surface of the template, it stops rising, and then the template cleaning and oiling walking driver 4 is started, and the template cleaning and oiling loop 2 is pushed by the push rod to make the template cleaning and oiling loop 2 step onto the template, and then the template cleaning and oiling track lifting drive mechanism is controlled to slightly The template cleaning and oiling loop 2 is lowered to contact the upper surface of the template, thereby entering the working position; after entering the working position, the template cleaning and oiling loop is controlled to move back and forth along the longitudinal direction of the template through the rollers by controlling the template cleaning and oiling walking driver. During the movement, the template cleaning loop is used to scrape and clean the template surface, and the template oiling loop is used to apply oil (release agent) to the template surface. Further, the preferred working mode is: during the overall forward movement of the template cleaning and oiling loop, the oil circuit of the oil pipe on the template oiling loop is closed, and no oiling is performed, and the template surface is only scraped and cleaned by the template cleaning loop; during the overall return of the template cleaning and oiling loop, the oil circuit of the oil pipe on the template oiling loop is opened, and the template surface is oiled by the template oiling loop. Alternatively, depending on the specific cleaning situation, if the template cannot be completely cleaned in one go, the template can be scraped and brushed back and forth to clean it. After it is completely cleaned, during the last return process, the template oiling loop oil circuit is opened, and the template surface is oiled using the template oiling loop (it should be noted that the template oiling loop is located on the front side of the forward direction of the template cleaning loop, so that during the return process, the template cleaning loop will not scrape the oil sprayed by the template oiling loop).

[0046] After the template cleaning and oiling work is completed, the template cleaning and oiling loop is returned to the initial position. The specific method is: the template cleaning and oiling walking driver 4 drives the template cleaning and oiling loop 2 to move to the tail, so that the template cleaning and oiling loop 2 is separated from the template, and then the template cleaning and oiling track lifting drive mechanism is controlled (the three lifting drive actuators descend synchronously), driving the template cleaning and oiling track to move downward as a whole, so that the template cleaning and oiling track is lower than the template and returns to the initial position.

[0047] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0048] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0049] The present invention is described above by way of example. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by those skilled in the art without inventive effort falls within the protection scope of the present invention.
