Description

Technical Field

[0001] The present invention relates to the technical field of wall maintenance equipment, and in particular to an external wall maintenance equipment for railway station buildings. Background Art

[0002] A railway station building refers to the building for passengers in a passenger station or a passenger and freight station; including: waiting room, ticket office, hall, passage, catering and entertainment rooms, toilets and washrooms, etc.; it should fully consider the needs of various activities such as passengers waiting for trains, getting on and off trains, and provide good environmental conditions and services, such as lighting, ventilation, heating, air conditioning, guidance and display, shopping, entertainment, accommodation, inquiry, communication, etc.

[0003] In order to ensure the aesthetics and safety of the station building and extend its service life, a railway station building usually needs to be maintained regularly. When maintaining the station building, the main content of the maintenance is to remove the dust, dirt and rust on the external wall of the station building. However, due to the height of the station building and it being a landmark building, its external shape has its own design features. The external wall of the station building is usually composed of arc surfaces, curved surfaces and other building surfaces with different convexities and concavities, which will cause traditional equipment to be unable to effectively care for the external wall of the station building. Using manual climbing for cleaning can solve the above problems, but there will be relatively large safety hazards, and when workers climb using a lifting platform or safety cable, their positions will also be restricted at high altitudes, and the efficiency of single - time maintenance will be very low. Summary of the Invention

[0004] The present invention discloses an external wall maintenance equipment for railway station buildings, aiming to solve the technical problems that existing cleaning equipment cannot effectively maintain the external wall of railway station buildings, and using manual labor will have relatively large safety hazards and the efficiency of single - time maintenance will be very low.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An external wall maintenance equipment for railway station buildings includes a lifting platform, and a driving mechanism for providing rotational power is arranged inside the lifting platform;

[0007] A locking mechanism that adapts to the deformation of the external wall and locks is arranged in the middle of the driving mechanism;

[0008] A maintenance mechanism for cleaning and painting protection of the external wall is arranged outside the locking mechanism;

[0009] The driving mechanism drives the maintenance mechanism to perform periodic revolution and switch the working mode of the maintenance mechanism, so as to realize the cleaning and painting protection of the external wall, and then cooperate with the locking mechanism to drive the maintenance mechanism to adaptively deform according to the shape of the external wall.

[0010] By setting a driving mechanism with a maintenance mechanism on the basis of a traditional lifting platform, the driving mechanism is used to cooperate with the climbing of the lifting platform to drive the maintenance mechanism to contact the outer wall of the railway station building, so as to maintain the outer wall. At the same time, the driving mechanism can change the working mode of the maintenance mechanism, so that the dirt on the outer wall can be cleaned and the metal outer wall can be painted and maintained, improving the working ability. Moreover, the additionally provided locking mechanism can cooperate with the extrusion of the outer wall by the maintenance mechanism to lock the maintenance mechanism after deformation and fitting, so that the maintenance mechanism can better maintain the outer wall of the railway building, thus improving the functionality and efficiency of the equipment.

[0011] In a preferred solution, the driving mechanism includes a base fixed to the middle of the lifting platform. A lower bottom plate is rotatably installed on the top of the base. A first motor is horizontally fixed on one side of the base. The output end of the first motor horizontally penetrates through the base and is connected to the lower bottom plate. An upper top plate is slidably installed on the top of the lower bottom plate. A turning plate is rotatably installed on the top of the upper top plate. A second motor is horizontally fixed on one side of the upper top plate. The output end of the second motor horizontally penetrates through the upper top plate and is connected to the turning plate. The locking mechanism is arranged inside the turning plate.

[0012] By setting a base with a lower bottom plate and an upper top plate structure on the basis of a traditional lifting platform, and at the same time, a turning plate structure is also arranged inside the upper top plate. The operation of the first motor and the second motor respectively drives the lower bottom plate and the turning plate to rotate, so that the maintenance mechanism located on the turning plate can contact the outer wall to be maintained, and the working mode can be switched according to requirements, thus ensuring the perfection and rationality of the operation of the equipment.

[0013] In a preferred solution, the locking mechanism includes a plurality of positioning rods slidably installed inside the turning plate. The plurality of positioning rods are divided into two groups and symmetrically distributed along the vertical direction at the upper and lower ends of the turning plate. One air chamber is respectively arranged on both sides of the upper and lower ends of the turning plate. A plug board is slidably installed inside each air chamber. A jet board is connected to the side of the air chamber located above. The jet board is horizontally fixed on the side of the turning plate. An air pump is horizontally fixed on one side of the upper top plate. The output end of the air pump horizontally penetrates through the upper top plate and is connected to the side of the air chamber located above. The maintenance mechanism is arranged outside each group of positioning rods.

[0014] By arranging a number of positioning rod structures slidably installed inside the flipping plate, as the maintenance mechanism located outside the positioning rod contacts and presses against the exterior wall to be maintained, the pressed positioning rod will undergo corresponding displacement, thereby changing the current shape of the maintenance mechanism, enabling the maintenance mechanism to better fit the surface of the exterior wall. And by using the air pressure generated by the air pump to push the plug plate inside the air chamber, driving the plug plate to press and engage with the displaced positioning rod, thereby realizing the fixation of the deformed maintenance mechanism and ensuring the perfection of the operation of the maintenance mechanism. The additionally provided jet plate can divert a part of the gas generated by the air pump to blow the exterior wall, thereby increasing the drying rate of the moisture after the maintenance mechanism wipes the exterior wall, and indirectly improving the working efficiency of the maintenance mechanism.

[0015] In a preferred solution, the maintenance mechanism includes a sponge scrubber fixed to the top of a group of the positioning rods. One end of the side surface of the flipping plate is horizontally fixed with a water outlet member, and the water outlet member is connected in communication with the inside of the sponge scrubber. One end of each of another group of several positioning rods is respectively fixedly installed with a brush. The other end of the side surface of the flipping plate is horizontally fixed with a glue spraying member, and the glue spraying member is distributed on the side of several of the brushes.

[0016] By respectively arranging a sponge scrubber and a brush structure at the side ends of the positioning rods, using the water outlet member to introduce clean water into the inside of the sponge scrubber, and using the operation of the driving mechanism and the locking mechanism to clean the exterior wall. At the same time, a single brush can brush off stubborn dirt, and the brush cooperating with the glue spraying member can paint the rusty parts of the metal exterior wall, thereby cooperating with the rotation of the flipping plate to simultaneously realize multiple functions, thus greatly improving the perfection and functionality of the operation of this equipment.

[0017] In a preferred solution, a first elastic member is fixedly connected between the interlayer of each positioning rod and the flipping plate, and a second elastic member is fixedly connected between the interlayer of each plug plate and the air chamber.

[0018] By arranging the first elastic member to provide a restoring force for the displaced positioning rod and the second elastic member to provide a restoring force for the displaced plug plate, thereby ensuring the perfection of the periodic operation of this equipment.

[0019] In a preferred solution, an adapter is slidably sleeved outside the output end of the air pump, the adapter is slidably engaged inside the air chamber, and a spring is horizontally fixed between the interlayer of the adapter and the upper top plate, and the spring is sleeved outside the output end of the air pump.

[0020] By providing a connecting piece structure pushed by a spring at the output end of the air pump, the connecting piece can be horizontally inserted into the interiors of two air chambers, thus ensuring the connection of the air path. At the same time, when the turning plate rotates, the squeezed connecting piece can slide out of the interior of the air chamber, further ensuring the rationality and perfection of the operation of this device.

[0021] In a preferred solution, a telescopic rod is fixedly connected between the sliding connection ends of the lower bottom plate and the upper top plate respectively.

[0022] By providing a telescopic rod to provide a driving force for the upper top plate that has lost the extrusion restriction, thus ensuring the rationality of the periodic operation of this device.

[0023] As can be seen from the above. The railway station house exterior wall maintenance device provided by the present invention, compared with the prior art, has the following improvements and advantages:

[0024] First: By providing a base with a lower bottom plate and an upper top plate structure on the basis of a traditional lifting platform, and at the same time, a turning plate structure is provided inside the upper top plate. By the operation of the first motor and the second motor respectively driving the lower bottom plate and the turning plate to rotate, the sponge wipes and brush structures respectively arranged on the turning plate can contact the exterior wall to be maintained in a switching manner according to actual needs. On the one hand, water is introduced into the sponge wipes through the water outlet parts to wipe and clean the common dirt on the exterior wall. On the other hand, a single brush can scrape and brush the stubborn dirt, and the brush cooperating with the glue spraying part can paint the rusty parts of the metal exterior wall, replacing manual maintenance, improving work efficiency and realizing multiple functions at the same time.

[0025] Second: Also, by providing a plurality of sliding positioning rod structures, as the sponge wipes and brushes on the outside of the positioning rods contact and squeeze the exterior wall to be maintained, the positioning rods will have corresponding displacements and change the current working forms of the sponge wipes and brushes, so that the cleaning end of this device can better fit the surface of the exterior wall. Then, by the air pressure of the air pump pushing the plug board inside the air chamber, driving the plug board to squeeze and engage with the displaced positioning rods, the fixed deformation of the sponge wipes and brushes can be realized, which can adapt to more peculiarly shaped walls, and at the same time ensure the stability and efficiency of this device during cleaning. The additionally provided air jet plate can divert a part of the gas generated by the air pump to blow the exterior wall, thereby further increasing the drying rate of the water after adding water and wiping the exterior wall by this device, and indirectly improving the work efficiency of this device.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described 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 of the embodiments.

[0038] A maintenance equipment for the exterior wall of a railway station building disclosed by the present invention is mainly applied to the scenario of maintaining the exterior wall of a railway station building.

[0039] Refer to Figures 1 to 10 , a maintenance device for the outer wall of a railway station building, including a lifting platform 1, and a driving mechanism 2 for providing rotational power is arranged inside the lifting platform 1;

[0040] A locking mechanism 3 that adapts to the deformation of the outer wall and locks is arranged in the middle of the driving mechanism 2;

[0041] A maintenance mechanism 4 for cleaning and painting protection of the outer wall is arranged outside the locking mechanism 3;

[0042] The driving mechanism 2 drives the maintenance mechanism 4 to perform periodic revolution and switch the working mode of the maintenance mechanism 4, so as to realize the cleaning and painting protection of the outer wall, and then cooperate with the locking mechanism 3 to drive the maintenance mechanism 4 to adaptively deform according to the shape of the outer wall.

[0043] In this embodiment: The user moves the lifting platform 1 to the lower part of the outer wall of the railway station building to be maintained, and at the same time starts the lifting platform 1, causing the lifting platform 1 to be lifted to a specified height. At this time, the user controls the driving mechanism 2 to rotate, driving the maintenance mechanism 4 to be in extrusion contact with the outer wall to be maintained. As the extrusion contact progresses, the maintenance mechanism 4 will deform correspondingly according to the shape of the extruded outer wall and simultaneously push the locking mechanism 3 until the maintenance mechanism 4 deforms and closely adheres to the outer wall to be maintained. At this time, the user controls the locking mechanism 3 to lock the deformed maintenance mechanism 4. After locking, the lifting platform 1 is started again, causing the lifting platform 1 to drive the maintenance mechanism 4 to move slowly downward. During the moving process, the maintenance mechanism 4 will clean and maintain the outer wall of the station building to complete the work process; and before the maintenance mechanism 4 is extruded and adhered to the outer wall of the station building, the user can start the driving mechanism 2 according to the need, causing the driving mechanism 2 to drive the maintenance mechanism 4 to rotate, so as to change the contact part between the maintenance mechanism 4 and the outer wall of the station building, causing the maintenance mechanism 4 to freely switch between the two functions of realizing water spraying and wiping on the outer wall and painting the rusty parts on the metal parts of the outer wall.

[0044] Among them, the lifting platform 1 can adopt an existing scissor lift, which is not fully drawn in the figure.

[0045] In the above solution, considering that it is convenient for this device to maintain the outer wall of the station building at different angles, the specific operation is as follows.

[0046] Refer to Figures 1 to 8, in a preferred embodiment, the driving mechanism 2 includes a base 201 fixed to the middle of the lifting platform 1. A lower bottom plate 202 is rotatably installed on the top of the base 201. A first motor 203 is horizontally fixed to one side of the base 201. The output end of the first motor 203 horizontally penetrates the base 201 and is connected to the lower bottom plate 202. An upper top plate 204 is slidably installed on the top of the lower bottom plate 202. A turning plate 205 is rotatably installed on the top of the upper top plate 204. A second motor 206 is horizontally fixed to one side of the upper top plate 204. The output end of the second motor 206 horizontally penetrates the upper top plate 204 and is connected to the turning plate 205. The locking mechanism 3 is arranged inside the turning plate 205.

[0047] In this embodiment: The user moves the lifting platform 1 below the outer wall of the railway station house to be maintained and simultaneously starts the lifting platform 1, causing the lifting platform 1 to rise to a specified height. At this time, the user controls the first motor 203 to rotate. The rotating first motor 203 will synchronously drive the lower bottom plate 202 and the upper top plate 204 to rotate, causing the maintenance mechanism 4 located on the turning plate 205 to be in pressing contact with the outer wall to be maintained; before the maintenance mechanism 4 is pressed and fitted to the outer wall of the station house, the user can start the second motor 206 according to needs, causing the second motor 206 to drive the turning plate 205 to rotate. The rotating turning plate 205 will drive the maintenance mechanism 4 to rotate synchronously, thereby changing the contact part between the maintenance mechanism 4 and the outer wall of the station house, enabling the maintenance mechanism 4 to freely switch between the two functions of spraying and wiping the outer wall and painting the rusty parts of the metal parts on the outer wall.

[0048] Among them, it should be added that: A telescopic rod 207 is fixedly connected between the sliding connection ends of the lower bottom plate 202 and the upper top plate 204. As the lower bottom plate 202 rotates, the relative distance between the upper top plate 204 and the wall will decrease. At this time, the upper top plate 204 will overcome the resistance of the telescopic rod 207 and relatively shorten with the lower bottom plate 202. At the same time, the telescopic rod 207 can also provide power for the extension of the upper top plate 204.

[0049] In the above solution, considering to ensure the stability of the deformed maintenance mechanism 4 when wiping the outer wall, the specific operation is as follows.

[0050] Refer to Figures 1 to 4 、 Figures 5 to 8, in a preferred embodiment, the locking mechanism 3 includes a plurality of positioning rods 301 slidably installed inside the turning plate 205. The plurality of positioning rods 301 are divided into two groups and symmetrically distributed along the vertical direction at the upper and lower ends of the turning plate 205. On both sides of the upper and lower ends of the turning plate 205, an air chamber 302 is respectively provided. Inside each air chamber 302, a plug plate 303 is slidably installed. A jet plate 304 is connected through the side of the air chamber 302 located above. The jet plate 304 is horizontally fixed on the side of the turning plate 205. An air pump 305 is horizontally fixed on one side of the upper top plate 204. The output end of the air pump 305 horizontally penetrates through the upper top plate 204 and is connected to the side of the air chamber 302 located above. The maintenance mechanism 4 is arranged outside each group of positioning rods 301.

[0051] In this embodiment: The rotating first motor 203 will synchronously drive the lower bottom plate 202 and the upper top plate 204 to rotate, causing the maintenance mechanism 4 located on the turning plate 205 to come into extrusion contact with the exterior wall to be maintained. As the maintenance mechanism 4 is extruded and deformed, the deformed maintenance mechanism 4 will synchronously push the positioning rod 301, causing the positioning rod 301 to move towards the inside of the turning plate 205 until the maintenance mechanism 4 is in close contact with the exterior wall. At this time, the user controls the air pump 305 to work. The gas generated by the air pump 305 will enter the inside of the air chamber 302 and push the plug plate 303 located inside the air chamber 302, causing the plug plate 303 to move and be engaged inside the plurality of positioning rods 301 that have moved, forming a fixation of the positioning rod 301. When the positioning rod 301 is fixed, the maintenance mechanism 4 located at the top of the positioning rod 301 will also be locked synchronously. When the maintenance mechanism 4 moves synchronously with the lifting platform 1, the stable maintenance mechanism 4 can more effectively wipe and maintain the exterior wall; at the same time, part of the gas entering the air chamber 302 will be ejected through the jet plate 304 and blow the place wiped by the maintenance mechanism 4, thereby improving the drying efficiency of the moisture at the wiping place.

[0052] Among them, it should be supplemented and explained that: A first elastic member 306 is fixedly connected between the interlayer of each positioning rod 301 and the turning plate 205. When the positioning rod 301 loses the extrusion of the maintenance mechanism 4, the first elastic member 306 can push the positioning rod 301 to move back to its original position; A second elastic member 307 is fixedly connected between the interlayer of each plug plate 303 and the air chamber 302. When the plug plate 303 loses the push of air pressure, the contracted second elastic member 307 can pull the plug plate 303 to move back to its original position.

[0053] Furthermore, it should be supplemented and explained that: A connecting piece 308 is slidably sleeved outside the output end of the air pump 305. The connecting piece 308 is slidably engaged inside the air chamber 302. A spring 309 is horizontally fixed between the connecting piece 308 and the upper top plate 204. The spring 309 is sleeved outside the output end of the air pump 305. When the turning plate 205 rotates, the squeezed connecting piece 308 will overcome the resistance of the spring 309 and disengage from the inside of the air chamber 302 until the connecting piece 308 is realigned with the side surface of an air chamber 302 again. At this time, the spring 309 that has lost the restraining force will push the connecting piece 308 again, causing the connecting piece 308 to snap back into the inside of the air chamber 302.

[0054] In the above solution, considering that dust and dirt will accumulate on the outer wall of the railway station building after long-term exposure and need to be processed, and the external metal wall of the railway station building will also peel off paint and rust after long-term exposure and requires maintenance treatment. The specific operations are as follows.

[0055] Refer to Figures 1 to 3 、 Figures 5 to 7 In a preferred embodiment, the maintenance mechanism 4 includes a sponge brush 401 fixed to the top of a set of positioning rods 301. One end of the side surface of the turning plate 205 is horizontally fixed with a water outlet member 402. The water outlet member 402 is connected to the inside of the sponge brush 401 in a through manner. The ends of another set of several positioning rods 301 are respectively fixed with a brush 403. The other end of the side surface of the turning plate 205 is horizontally fixed with a glue spraying member 404. The glue spraying member 404 is distributed on the side surfaces of several brushes 403.

[0056] In this embodiment: When the rotating first motor 203 synchronously drives the lower bottom plate 202 and the upper top plate 204 to rotate, the sponge brush 401 located on the turning plate 205 will be in extrusion contact with the outer wall to be maintained. At this time, the user introduces clean water into the inside of the water outlet member 402, and the water outlet member 402 will introduce the clean water into the inside of the sponge brush 401. Along with the slow descent of the lifting platform 1, the sponge brush 401 in contact with the outer wall will moisten and wipe the outer wall at the same time. And when the user starts the second motor 206 according to the need, the second motor 206 drives the turning plate 205 to rotate. The rotating turning plate 205 will drive the maintenance mechanism 4 to rotate synchronously, causing the lower brush 403 to contact the outer wall. At this time, along with the slow descent of the lifting platform 1, the brush 403 in contact with the outer wall can brush off the stubborn stains adhering to the outer wall. And when the brush 403 moves to the place with rust on the metal wall surface, at this time, the user introduces glue paint into the inside of the glue spraying member 404, and the glue paint will adhere to the brush 403 and can brush the paint onto the metal wall surface along with the movement of the brush 403.

[0057] Among them, it should be noted that: one end of the water outlet part 402 and one end of the glue spraying part 404 are respectively rotatably installed with a liquid guide pipe 405, and the two liquid guide pipes 405 are respectively connected to the inside of the water outlet part 402 and the brush 403 in a penetrating manner; used to respectively introduce clean water into the inside of the water outlet part 402 and introduce glue paint into the inside of the glue spraying part 404.

[0058] Working principle: The user moves the lifting platform 1 to the lower part of the outer wall of the railway station building to be maintained, and at the same time starts the lifting platform 1, causing the lifting platform 1 to rise to the specified height. At this time, the user controls the first motor 203 to rotate, and the rotating first motor 203 will synchronously drive the lower bottom plate 202 and the upper top plate 204 to rotate, causing the sponge wipe 401 on the turning plate 205 to be in extrusion contact with the outer wall to be maintained. As the sponge wipe 401 is extruded and deformed, the deformed sponge wipe 401 will synchronously push the positioning rod 301, causing the positioning rod 301 to move towards the inside of the turning plate 205 until the sponge wipe 401 is in close contact with the outer wall. At this time, the user controls the air pump 305 to work, and the gas generated by the air pump 305 will enter the inside of the air chamber 302 and push the plug plate 303 located inside the air chamber 302, causing the plug plate 303 to move and be engaged inside a number of the moved positioning rods 301, forming a fixation of the positioning rods 301. When the positioning rods 301 are fixed, the sponge wipe 401 at the top of the positioning rods 301 will also be locked synchronously. At this time, the user introduces clean water into the inside of the water outlet part 402, and the water outlet part 402 will then introduce the clean water into the inside of the sponge wipe 401. Along with the slow descent of the lifting platform 1, the sponge wipe 401 in contact with the outer wall will humidify and wipe the outer wall at the same time, and a part of the gas that enters the inside of the air chamber 302 will be ejected through the air jet plate 304 and blow the place wiped by the sponge wipe 401, thereby improving the drying efficiency of the moisture at the wiping place; and before the maintenance mechanism 4 is pressed against the outer wall of the station building, the user can start the second motor 206 according to the need, causing the second motor 206 to drive the turning plate 205 to rotate, and the rotating turning plate 205 will drive the maintenance mechanism 4 to rotate synchronously, thereby changing the contact part between the maintenance mechanism 4 and the outer wall of the station building, causing the brush 403 below to be in contact with the outer wall. At this time, along with the slow descent of the lifting platform 1, the brush 403 in contact with the outer wall can brush off the stubborn stains adhering to the outer wall, and when the brush 403 moves to the place with rust on the metal wall surface, at this time the user introduces glue paint into the inside of the glue spraying part 404, and the glue paint will adhere to the brush 403 and can brush the paint onto the metal wall surface as the brush 403 moves.
