Description

Technical Field

[0001] The utility model relates to the technical field of mold cleaning, in particular to a cleaning structure and a mold cleaning device thereof. Background Art

[0002] In railway construction, sleeper is an important component for supporting railway tracks, and its quality and stability are directly related to the safety and smooth operation of railway lines. Traditionally, railway sleepers are mainly manufactured by the process of casting with cement, and this process highly depends on sleeper molds. Such molds are designed with an inner cavity in a long groove shape for accommodating and shaping the poured cement, and finally forming railway sleepers that meet the specification requirements.

[0003] However, in the actual production process, after each use of the sleeper mold, residual cement often adheres to its inner wall, which not only increases the difficulty of mold maintenance, but also in the subsequent casting and molding process, these residues will directly affect the surface quality and dimensional accuracy of the newly manufactured sleepers, and may further affect the overall laying quality and operation safety of the railway.

[0004] In view of the above problems, the existing solutions mainly rely on manual operations, such as using tools like hand-held angle grinders to polish and clean the inner wall of the mold. Although this method can remove the residual cement to a certain extent, there are two significant defects: one is the high labor cost, which requires a large amount of labor input; the other is the low polishing efficiency, which affects the production cycle and efficiency, and cannot meet the requirements of rapid and efficient production of sleepers for large-scale railway construction.

[0005] Therefore, in view of the limitations of the current technical means and the actual needs, developing a tool that can efficiently, automatically or semi-automatically clean the residual cement on the inner wall of the sleeper mold has become a key technical problem that needs to be solved urgently by those skilled in the art.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The purpose of the present invention is to provide a cleaning structure and its mold cleaning device to solve the problems existing in the prior art. By using a V-shaped spring and a limiting member to restrict the position of the connecting member, and then limit the position of the cleaning head, the cleaning head can be symmetrically installed to clean the two opposite wall surfaces of the mold, improve the cleaning efficiency, and reduce the labor cost.

[0030] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] As Figures 1 to 6 shown, the present invention provides a cleaning structure, including a bracket 1, an adjustment assembly 2, and a cleaning head 3. Among them, the bracket 1 is used to support other structures and is connected to the fixed plate 4 or the base so that it can be driven by a moving device to move and change the cleaning position. The cleaning head 3 is used to clean the surface to be cleaned, and it can be provided with a wire brush, a brush, etc. The action mode of the cleaning head 3 can be rotation, vibration, or a combination of the two. The adjustment assembly 2 includes a V-shaped spring 21, a connecting member 22, and a limiting member 23. The V-shaped spring 21 can be a folding plate spring with two spring arms or a torsion spring with two spring arms. The connecting member 22 includes a connecting body and a first end and a second end connected to both ends of the connecting body. The first end is hinged to the bracket 1, and the second end is connected to the cleaning head 3. The connecting body is connected to the spring arms of the V-shaped spring 21. Thus, by squeezing the connecting member 22 inward, the V-shaped spring 21 can be compressed, and then the V-shaped spring 21 can provide an outward elastic force to the connecting member 22. During the cleaning process, when the surface to be cleaned has undulations, good contact between the cleaning head 3 and the surface to be cleaned can still be achieved. The limiting member 23 is connected to the bracket 1, and the limiting member 23 can adopt structural forms such as a cam and a strut. By setting the limiting member 23, it can abut against the side of the connecting body away from the spring arm, that is, the expansion degree of the V-shaped spring 21 can be limited by the limiting member 23, so that the distance between the cleaning heads 3 can conform to the size of the part to be cleaned. For example, it can adapt to a mold groove with a certain width, and the cleaning head 3 can be smoothly inserted into the groove and fit the inner wall of the groove.

[0032] The utility model utilizes the V-shaped spring 21 to provide an outward supporting force and the limiting member 23 to provide an inward supporting force. Thus, through the cooperation of the V-shaped spring 21 and the limiting member 23, the relative distance between the cleaning heads 3 can be adjusted, so as to limit the positions of the cleaning heads 3, and the cleaning heads 3 can be symmetrically installed to clean the opposite two wall surfaces of the mold, improving the cleaning efficiency and reducing the labor cost.

[0033] As shown in Figure 3 Figure, the limiting member 23 can be an eccentric adjusting wheel. The eccentric adjusting wheel is installed on the bracket 1 through bolts. The center of the eccentric adjusting wheel does not coincide with the rotation center of the eccentric adjusting wheel. The wheel surface of the eccentric adjusting wheel abuts against the connecting body. Thus, when the eccentric adjusting wheel is rotated, the contact position between the eccentric adjusting wheel and the connecting body can be changed, and the opening angle of the connecting member 22 can be changed by combining the rotation of the eccentric adjusting wheel with the elastic force of the V-shaped spring 21. The end of the bolt is provided with a polygonal prism that can be clamped by a wrench. The angle of the eccentric adjusting wheel can be adjusted by twisting the polygonal prism. After the adjustment is in place, the bolt is tightened with a nut to fix the eccentric adjusting wheel.

[0034] The connecting member 22 can adopt a telescopic structure. The first end of the connecting member 22 is telescopically connected to the connecting body. For example, the first end has a plug rod, and the connecting body has a plug hole for cooperating with the plug rod. After adjusting the relative position between the first end and the connecting body, the connecting body and the first end can be locked by using a first fastener. The first fastener can be a fastening screw or a bolt. The above method is convenient for connecting the connecting body with the spring arm.

[0035] It can also include a guiding and supporting member 24. The guiding and supporting member 24 is installed on the bracket 1. The connecting body is a rectangular body. One surface of the rectangular body is in contact connection with the spring arm, and the other surface away from the spring arm is in contact with the wheel surface of the eccentric adjusting wheel. The remaining two opposite surfaces of the rectangular body are slidably buckled in the guiding groove of the guiding and supporting member 24. Thus, when adjusting the opening angle of the rectangular body, the guiding and supporting member 24 can be used for constraint and guidance. The guiding and supporting member 24 can adopt a double-piece buckling method and is fixed by passing through the bolt for fixing the eccentric adjusting wheel. The eccentric adjusting wheel is located in the guiding groove. In addition, to further ensure the fixing effect, at least one more bolt can be provided to fix the guiding and supporting member 24 on the bracket 1.

[0036] The second end of the connecting member 22 can also be telescopically connected to the connecting body. For example, the second end has a plug rod, and the connecting body has a plug hole for cooperating with the plug rod. After adjusting the relative position between the second end and the connecting body, the second end and the connecting body can be locked by using a second fastener. The second fastener can be a fastening screw or a bolt. By adjusting the telescopic length of the second end, the position of the cleaning head 3 can be adaptively adjusted, and the relative distance between the cleaning heads 3 can be adjusted in cooperation with the adjustment of the limiting member 23.

[0037] As shown in Figure 4 Figure 1, the bracket 1 can adopt a U-shaped frame body. The arms of the U-shaped frame body are provided with open slots 11. The V-shaped spring 21 is installed in the open slots 11. The limiting members 23 are connected to both sides of the open slots 11. Moreover, an adjusting assembly 2 and a cleaning head 3 can be installed on each arm of the U-shaped frame body. To ensure the structural stability of the two arms, a second strengthening member 10 can be arranged between the two arms. The second strengthening member 10 can adopt a strengthening plate or a strengthening rod. When a strengthening rod is adopted, it can penetrate through the two arms and then be locked by a nut. Through the U-shaped frame body, the two groups of cleaning heads 3 can be fixed. At this time, each arm is connected to a group of cleaning heads 3; or a single group of cleaning heads 3 can be fixed. At this time, the two arms are jointly connected to a group of cleaning heads 3. To ensure the action consistency and connection stability of the connecting members 22 connected to the two arms, a first strengthening member 9 can be adopted. The first strengthening member 9 can adopt a strengthening plate or a strengthening rod. When a strengthening plate is adopted, it can be fixed to the connecting member 22 by bolts, thereby connecting the two connecting members 22 into a whole.

[0038] As shown in Figure 3 Figure 2, the cleaning head 3 can include a brush body 31, a carrier frame 32 and a double fork arm 33. The middle part of the double fork arm 33 is hinged to the second end of the connecting member 22. The fulcrum of the double fork arm 33 is hinged to the carrier frame 32, that is, the carrier frame 32 can deflect at an angle in the pitching direction relative to the second end. Thus, it can better adapt to the inclination angles of the two side walls of the mold. The brush body 31 is rotatably connected to the carrier frame 32. The carrier frame 32 is used to support the rotation of the brush body 31. At the same time, when the brush body 31 is driven to rotate, it will not affect the angular deflection of the carrier frame 32.

[0039] As shown in Figures 1 to 6 Figure 3, the present utility model also provides a mold cleaning device, which includes a fixing plate 4 and the cleaning structure described above. One group or multiple groups of cleaning structures can be provided. The bracket 1 of the cleaning structure is installed on the fixing plate 4 to realize the connection of the cleaning structure. It also includes a driving device 5. The driving device 5 is connected to the cleaning head 3 through a flexible shaft 8. The flexible shaft 8 can better adapt to the power transmission path and is not affected by the adjustment of the distance between the cleaning heads 3. The driving device 5 can adopt a power source such as a hydraulic motor, a pneumatic motor or an electric motor. Through the fixing plate 4, the whole mold cleaning device is installed on a moving part such as a manipulator to realize the change of the cleaning position.

[0040] As shown in Figure 5As shown, it may further include a spur gearbox 6. The spur gearbox 6 includes a first housing, a driving gear 61 located in the first housing, and a driven gear 62 meshing with the driving gear 61. The driving gear 61 is connected to the driving device 5, and the driven gear 62 is connected to the flexible shaft 8. The driving gear 61 can be arranged in the middle, and according to the number of cleaning heads 3, the driven gears 62 are evenly arranged around the driving gear 61. Preferably, two groups of a total of four cleaning heads 3 are provided. At this time, four driven gears 62 meshing with the driving gear 61 are correspondingly arranged, and each driven gear 62 is connected to a separate flexible shaft 8.

[0041] Combined Figure 6 As shown, it may further include a bevel gearbox 7. The bevel gearbox 7 includes a second housing, a driving bevel gear 71 located in the second housing, and a driven bevel gear 72 meshing with the driving bevel gear 71. The driving bevel gear 71 is connected to the flexible shaft 8, and the driven bevel gear 72 is connected to the cleaning head 3. The flexible shaft 8 can enter from the top of the bevel gearbox 7 and be connected to the driving bevel gear 71. After the power is reversed through the meshing of the driving bevel gear 71 and the driven bevel gear 72, the power is output to the cleaning head 3.

[0042] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
