Description

Technical Field

[0001] The invention relates to the field of manufacturing CRTS III type track slabs for high-speed railways, and in particular to an automatic cleaning device for CRTS III type ballastless track slab moulds. Background Art

[0002] In the past decade, the construction level of my country's high-speed railway and underground rail transportation industries has continued to develop with high quality, and ballastless track structures have been widely adopted, among which CRTS III slab track structures are widely used. However, the construction process of CRTSS III slab track is numerous, the technology is complex, and the quality standards are high. At the same time, in order to meet the domestic demand for more than one million track plates per year, the current production tends to be automated assembly lines.

[0003] In the automated production line, the track slab moulds are used in continuous circulation. After the track slab demoulding process is completed, some concrete will inevitably remain on the mould surface due to the inconsistency of the mould surface quality and the quality of the release agent spraying. Therefore, the casting area on the inner surface of the mould needs to be thoroughly cleaned before the next step to remove the remaining concrete debris in the mould to facilitate subsequent processes.

[0004] At present, traditional mold cleaning methods are still used in the pedestal method and semi-automatic production lines, which are all completed manually. The cleaning work is cumbersome, labor-intensive and time-consuming, and the labor intensity of workers is high; the dust generated during cleaning causes certain harm to human health; and the curved surfaces and dead corners such as the rail platform are not easy to clean, and the consistency and quality of cleaning cannot be guaranteed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an efficient, reliable, comprehensive, accurately controllable CRTSⅢ type track plate mold automatic cleaning device to solve the above-mentioned problems.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is: An automatic cleaning device for high-speed railway CRTSⅢ type track plate molds, comprising: a support frame, a first moving crossbeam and a second moving crossbeam, the support frame is composed of four support frame columns, two longitudinal beams and two crossbeams, the support frame longitudinal beams are provided with frame racks and frame slide rails, the moving crossbeam is connected between the two frame longitudinal beams, and can be driven by a servo motor and a gear arranged thereon to move along the length direction of the frame longitudinal beams, the moving crossbeam is provided with a rack and a guide rail in the transverse direction, each moving crossbeam is provided with two side wall roller brush modules that can be moved in the transverse direction, one bottom plate roller brush module and two rail support cleaning devices The base of the side wall roller brush module is driven by a servo motor, a gear and a rack mounted on the moving crossbeam, and can move laterally along the crossbeam. The base of the side wall roller brush module is installed with a motor roller brush assembly that can be lifted and lowered by floating up and down through a cylinder, a slide rail and a slider assembly. The base of the bottom plate roller brush module is fixedly installed on the moving crossbeam according to the position of the rail support platform, and is installed with at least one group of bottom plate roller brushes that can be lifted and lowered that are arranged laterally and driven by a motor by floating up and down through a cylinder, a slide rail and a slider assembly. The base of the rail support platform cleaning module is fixedly installed on the moving crossbeam, and is installed with a flexible module that can be lifted and lowered by floating through a screw motor, a slide rail and a slider assembly. The flexible module consists of a double rocker roller brush and a flat brush. The double rocker roller brush is installed on the lower end of the base of the rail support platform cleaning module through a hinge and a spring, and a motor-driven roller brush is installed at the lower end of the rocker arm for cleaning the curved surface area of ​​the rail support platform. The flat brush is flexibly connected to the lower end of the base of the rail support platform cleaning module through four springs. The flat brush is also provided with a vibrator for cleaning the flat surface area of ​​the rail support platform.

[0007] Due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The present invention adopts two groups of symmetrically arranged moving beams. The two moving beams can move along the full-size longitudinal direction of the track plate mold. The cleaning devices thereon can perform cleaning operations independently or cross-complementary operations, which greatly improves the operating efficiency of the equipment and can ensure the rhythm of the continuous production line.

[0008] 2. The flexible cleaning module of the rail support platform adopts a dual-area cleaning mode. The flat part adopts the cleaning mode of "spring + vibration flat brush", and the curved area adopts the cleaning mode of "spring rocker arm + roller brush". During the downward pressure of the entire module, the compaction cleaning of the vibration flat brush and the surface cleaning of the rocker arm roller brush are realized at the same time, and the cleaning work of multiple surfaces of the entire rail support platform is completed in one stroke. While the overall rail support platform cleaning module is lifted, under the action of the spring, the flat brush and the rocker arm roller brush can be reset to the initial position to prepare for the cleaning work of the next group of rail support platforms. The above design not only ensures the cleaning quality of the rail support platform area, but also greatly improves the overall cleaning efficiency.

[0009] 3. In the two movable beams of the present invention, the side wall roller brushes installed thereon can realize full-size movement in the lateral direction of the track plate mold, so that the side wall roller brushes can cover all the two end lateral side walls of the mold when working, and at the same time, when the beam moves longitudinally, the two longitudinal side walls can be cleaned at one time.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1 As shown, an automatic mold cleaning device for a high-speed railway CRTSⅢ type track plate mold includes a support frame 1, a first moving beam 2 and a second moving beam 3.

[0018] like Figure 2 As shown, the support frame includes four columns 1-1, two end beams 1-2 and two side beams 1-3, and the side beams are equipped with slide rails 1-4 and racks 1-5.

[0019] like Figure 3 As shown, the first moving beam 2 and the second moving beam 3 have the same structure, and the installation directions are opposite. The first moving beam 2 is taken as an example for explanation. The first moving beam 2 is composed of a moving beam body 2-1, two sets of bottom plate roller brush modules 2-2, two sets of side wall roller brush modules 2-3 and two sets of rail cleaning modules 2-4. The main body of the first moving beam 2 is the moving beam body 2-1, and its end is floatingly installed on the supporting frame side beam 1-3 through a slider 2-5, and the servo motors 2-6 at both ends can drive the gears meshing with the rack 1-5 on the supporting frame side beam 1-3, so that the moving beam moves longitudinally along the slide rail 1-4 on the supporting frame side beam 1-3.

[0020] Two beam slide rails 2-8 are installed on the edge of the top of the moving beam body 2-1, and a beam rack 2-9 is installed in the middle. Two sets of side wall roller brush modules 2-3 are installed on the moving beam body 2-1 in a floating manner and can move horizontally. The rail support cleaning module 2-4, which is fixed in a horizontal position, can move in a vertical direction. The bottom plate roller brush module 2-2, which is fixed in a horizontal position, is installed on the moving beam body 2-1 in a floating manner and can only move in a vertical direction.

[0021] like Figure 4 As shown, the bottom plate roller brush module 2-2 is composed of a bottom plate roller brush module lifting bracket 2-2-1, a bottom plate roller brush module lifting cylinder 2-2-2, a bottom plate roller brush module frame 2-2-3, a bottom plate roller brush module slide rail bracket 2-2-4, a bottom plate roller brush module slide rail 2-2-5, a bottom plate roller brush 2-2-6 and a bottom plate roller brush cover 2-2-7. The bottom plate roller brush module lifting bracket 2-2-1 and the bottom plate roller brush module slide rail bracket 2-2-4 are fixed on the moving crossbeam body 2-1, and move up and down under the drive of the vertical sliding system composed of the bottom plate roller brush module lifting cylinder 2-2-2, the bottom plate roller brush module slide rail 2-2-5 and the slider. Two sets of bottom plate roller brushes 2-2-6 are driven by a motor to clean the mold bottom plate.

[0022] like Figure 5 As shown, the side wall roller brush module lifting bracket 2-3-1 can be driven by a horizontal sliding system composed of a side wall roller brush module servo motor 2-3-8, a side wall roller brush module driving gear 2-3-9 and a side wall roller brush module transverse sliding slider 2-3-10 to move laterally, so that the entire side wall roller brush module 2-3 can cover the width of the track plate laterally. The side wall roller brush motor 2-3-4 is fixed on the side wall roller brush bracket 2-3-3 and drives the side wall roller brush 2-3-5 to rotate. The vertical lifting movement of the side wall roller brush 2-3-5 and the side wall roller brush motor 2-3-4 is driven by a vertical sliding system composed of a side wall roller brush module lifting cylinder 2-3-2, a side wall roller brush lifting slide rail 2-3-7 and a side wall roller brush lifting slide 2-3-6.

[0023] like Figure 6As shown, the rail platform cleaning module mounting bracket 2-4-1 of the two sets of rail platform cleaning modules 2-4 is fixedly mounted on the movable crossbeam body 2-1, and is laterally positioned by the position of the mold rail platform part. The rail platform cleaning module lifting bracket 2-4-2 is driven by a vertical sliding system composed of a screw motor 2-4-3, a rail platform cleaning module lifting slide rail 2-4-4 and a slider to perform lifting and lowering movements. Two sets of rocker arms 2-4-6 are hinged on both sides of the lower end of the rail platform cleaning module lifting bracket 2-4-2, and the opening angle is tensioned and controlled by the rocker arm tensioning spring 2-4-12. The outer ends of the two sets of rocker arms 2-4-6 are installed with motor-driven rail platform roller brushes 2-4-7 for cleaning the curved surface of the rail platform, and the inner ends are rocker arm limit cams 2-4-11 for limiting the maximum opening angle of the rocker arms. A flat brush bracket 2-4-9 is fixedly installed at the lower end of the lifting bracket 2-4-2 of the rail platform cleaning module, and a flat brush 2-4-5 is floatingly installed on the lower side of the flat brush bracket 2-4-9 through four sets of flat brush support springs 2-4-8 for cleaning the flat surface of the rail platform. The flat brush 2-4-5 is vibrated by a flat brush excitation motor 2-4-10.

[0024] Working principle of the present invention: The mold car runs along the assembly line to the mold cleaning station. When the mold car stops at the set position, the system automatically reads the track plate model information of the current mold built-in chip. The system selects the initial positions of the first moving beam 2 and the second moving beam 3 according to the track plate model and the stop position. The first moving beam 2 reaches the mold end at its proximal end, and the second moving beam 3 reaches the middle position of the mold. Each cleaning module starts working.

[0025] The bottom plate roller brush module 2-2 on the first movable crossbeam 2 is driven by the bottom plate roller brush module lifting cylinder 2-2-2 to descend to the working height, and the bottom plate roller brush 2-2-6 is turned on to clean the bottom plate. As the bottom plate is cleaned, the first movable crossbeam 2 moves longitudinally under the drive of the servo motor, from the end of the mold to the middle position of the mold. When it moves to the working distance between the two sets of side wall roller brush modules 2-3 and the side wall of the end of the mold, the first movable crossbeam 2 stops. The side wall roller brush module 2-3, whose vertical initial position is at a high position and whose horizontal initial position is in the middle of the mold, descends to the working height, and the side wall roller brush motor 2-3-4 starts and rotates the side wall roller brush 2-3-5. At the same time, the two sets of side wall roller brush modules 2-3 translate from the middle position of the movable crossbeam body 2-1 to the side to complete the cleaning of the side wall of the mold end.

[0026] When the above movement is completed, the first movable beam 2 continues to move longitudinally toward the middle position of the mold. At this time, the side wall roller brush module 2-3 on the side of the mold continues to clean the side wall of the mold, and the bottom plate roller brush module 2-2 continues to clean the bottom plate of the mold.

[0027] When the first movable crossbeam 2 moves to the point where the rail platform cleaning module 2-4 is aligned with the rail platform on the mold, the first movable crossbeam 2 stops again, and the rail platform cleaning module 2-4 slowly descends under the drive of the screw motor 2-4-3, and at the same time, the rail platform roller brush 2-4-7 and the flat plate brush 2-4-5 start working.

[0028] like Figure 7 As shown, the initial position of the rail support roller brush 2-4-7 is determined by the rocker arm tensioning spring 2-4-12, so that the rail support roller brush 2-4-7 can be close to the inclined surface inside the rail support when it descends and contacts the mold. The outer edge of the rail support roller brush 2-4-7 has a rim with a radius smaller than the bristles, so that the pressing distance between the roller brush and the mold surface is controlled within a suitable value range.

[0029] like Figure 8 As shown, as the rail support platform cleaning module 2-4 further descends, the outer edge rim of the rail support platform roller brush 2-4-7 slides along the curved surface of the rail support platform, and overcomes the tension of the rocker arm tensioning spring 2-4-12 to open the rocker arm 2-4-6 outward, driving the rail support platform roller brush 2-4-7 to gradually clean the curved surface of the rail support platform.

[0030] like Fig. 9 As shown, when the rail platform cleaning module 2-4 descends to the maximum stroke, the flat brush support spring 2-4-8 is compressed, so that the flat brush 2-4-5 is flexibly in contact with and pressed against the flat surface of the rail platform. At the same time, the flat brush excitation motor 2-4-10 is started and provides an exciting force for the floatingly mounted flat brush 2-4-5, so that the flat brush 2-4-5 cleans the flat surface of the rail platform through a small distance reciprocating motion. At this time, the rail platform roller brush 2-4-7 moves to the highest point and is limited by the contact between the rocker arm limit cam 2-4-11 and the horizontal part of the lower end of the rail platform cleaning module mounting bracket 2-4-1. At this time, the tension of the rocker arm tensioning spring 2-4-12 reaches the maximum value.

[0031] After the above actions are completed, the screw motor 2-4-3 drives the bottom plate roller brush module 2-2 to rise and finally detach from the mold, and the cleaning of the single rail platform is completed. Then the first moving beam 2 is restarted from the parked state and moves longitudinally to the middle position of the mold, and continues to clean the side walls and bottom of the mold until it reaches the next rail platform position. The rail platform cleaning module 2-4 repeats the above actions until the working surface of the first moving beam 2 is connected with the working surface of the second moving beam 3, and the cleaning of the entire mold is completed.

[0032] While the first moving beam 2 starts the above series of actions, the second moving beam 3 synchronously performs the actions in the opposite direction to the first moving beam, but the roller brush assembly moves in the same way, until the working surfaces of the two sets of side wall roller brush modules 2-3 on the second moving beam 3 reach the end face of the mold. At this time, the two side wall roller brush modules 2-3 are driven by the servo motor to move horizontally from the two sides of the mold along the mold end face to the middle direction of the mold horizontal direction, and clean the mold end face. After the above actions are completed, the side wall roller brush module 2-3 is driven by the side wall roller brush module lifting cylinder 2-3-2 to rise and leave the mold height, and then the second moving beam 3 continues to move toward the end face of the mold until the cleaning working surface of the bottom plate cleaning roller brush module 2-2 covers the end of the bottom face of the mold.

[0033] When all the above actions are completed, each module on the two sets of moving beams is lifted to a height that is separated from the mold, and the mold leaves the mold cleaning station. Then the two moving beams move longitudinally to the initial position and wait for the next set of molds to enter the work. At this point, the system completes a typical mold cleaning workflow.

[0034] It should be noted that, in this document, relational terms such as one and two are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the 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.
