A special safety protection device for bridge erecting machines

Abstract

This utility model discloses a safety protection device for special equipment such as bridge erecting machines, including a base plate with a housing fixedly connected to it, and the housing having a cover. This utility model utilizes a motor-driven rod to rotate a wheel, which intermittently contacts a piston. When the wheel is not in contact with the piston, the piston can move within the housing with the help of a spring, pushing airflow into the pipeline. This causes a rubber sleeve to briefly inflate and contact the warning panel, causing the warning panel to vibrate and thus clean it. This avoids the problem of stubborn stains and accelerated dust accumulation caused by residual water during rinsing. Furthermore, the vibration generated by the rubber sleeve contact, instead of dry brushing, reduces dust generation during cleaning, lowers the possibility of dust re-adhesion, and the flexible contact of the rubber sleeve also reduces the risk of scratching the warning coating on the warning panel surface, making it easier to maintain the clarity and readability of the text.

Description

Technical Field

[0001] This utility model relates to the field of protection-related technology, and in particular to a safety protection device for special equipment such as bridge erecting machines. Background Technology

[0002] During bridge erection machine construction, safety-compliant protective signs must be set up in and around its working area, including conspicuous warning signs, clear no-entry signs, and clear warning lines. These signs effectively remind passersby and nearby workers of the existence of the construction area, clearly warn of potential risks, and thus provide necessary safety reminders and protections for the safety of workers and the surrounding environment.

[0003] The existing announcement number is CN222666624U, which describes a safety protection device for special equipment of a bridge erecting machine. By starting a water pump, the water pump draws water from two water tanks through a connecting pipe into the inside of a water supply pipe. The water then enters the water distribution frame and is sprayed outward through multiple outlet pipes and nozzles. The sprayed water directly hits the outer surface of the warning board, effectively rinsing it and cleaning away the dust adhering to the surface of the warning board. This achieves the purpose of effectively cleaning the dust adhering to the outer surface of the warning board.

[0004] While existing protective devices can provide warnings, the rinsing function relies on spraying water from nozzles. If the water pressure is not properly controlled, water may remain on the surface of the warning board. After drying, this water may combine with dust to form stubborn stains, which may accelerate dust accumulation. The brush board uses a dry brushing method, which can easily generate dust during cleaning. This dust may re-adhere to the warning board or surrounding equipment. Furthermore, if the hard brush is used for a long time, it may scratch the warning coating on the surface of the warning board, affecting the clarity and readability of the text. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety protection device for special equipment such as bridge erecting machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A safety protection device for a bridge erecting machine includes a base plate, a housing fixedly connected to the base plate, a cover provided in the housing, a motor fixedly connected to the cover, the output end of the motor being rotatably connected through the cover, a rod fixedly connected to the motor output end, a wheel rotatably connected to the rod, a piston in contact with the wheel, and multiple springs fixedly connected at equal intervals between the piston and the inner wall of the housing, two pipes fixedly connected to the cover, each pipe having a rubber sleeve fixedly connected to one end, a frame fixedly connected to the base plate, and a warning plate provided at one end of the frame.

[0007] Preferably, the cover is fixedly connected to a battery, the cover is fixedly connected to a housing, and the battery and the cover are placed inside the housing.

[0008] Preferably, the indicator panel is placed corresponding to the two rubber sleeves.

[0009] Preferably, a rubber pad is fixedly connected at the contact point between the cover and the box.

[0010] Preferably, the frame is fixedly connected to the base plate with multiple reinforcing ribs.

[0011] Preferably, the frame is fixedly connected to the indicator board by bolts.

[0012] Preferably, the housing and the cover are fixedly connected by bolts.

[0013] The beneficial effects of this utility model are as follows: 1. Through the coordination of the base plate, housing, cover, motor, rod, wheel, piston, spring, pipe, and rubber sleeve, the motor drives the rod to rotate the wheel. The wheel intermittently contacts the piston. When the wheel is not in contact with the piston, the piston can move within the housing with the help of the spring force, pushing airflow into the pipe. This causes the rubber sleeve to briefly inflate and contact the indicator panel, causing the indicator panel to vibrate and achieve cleaning. This avoids the problem of stubborn stains and accelerated dust accumulation caused by residual water during rinsing. At the same time, the vibration generated by the contact of the rubber sleeve replaces the dry brush mode, which reduces dust during the cleaning process and reduces the possibility of dust re-adhesion. In addition, the flexible contact of the rubber sleeve also reduces the risk of scratching the warning coating on the surface of the indicator panel, and is more conducive to maintaining the clarity and readability of the text. 2. By coordinating the enclosure, cover, and motor, the enclosure can shield the motor from falling debris and other contaminants in the construction environment, reducing direct impact on the motor and helping to maintain its stable operation, thus ensuring the reliable operation of the entire device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1, referring to Figures 1 to 5 A special safety protection device for a bridge erecting machine includes a base plate 1, a housing 2 fixedly connected to the base plate 1, a cover 3 on the housing 2, a motor 4 fixedly connected to the cover 3, the model of the motor 4 being selected according to actual working requirements, the output end of the motor 4 being rotatably connected to the cover 3, a rod 5 fixedly connected to the output end of the motor 4, a wheel 6 rotatably connected to the rod 5, and a piston 7 in contact with the wheel 6. The piston 7 is made of wear-resistant nitrile rubber, its size matching the inner cavity of the housing 2, and a sealing ring on its edge to ensure airtightness. The piston 7 is fixedly connected at equal distances to the inner wall of the housing 2. Multiple springs 8 provide a force to push the piston 7 when the wheel 6 is not in contact with it. The cover 3 is fixedly connected to two pipes 9. Airflow entering the housing 2 through the pipes 9 inflates the rubber sleeve 10, allowing it to contact the indicator plate 12 and vibrate it in a flexible contact manner. Rubber sleeves 10 are fixedly connected to one end of each pipe 9. A frame 11 is fixedly connected to the base plate 1, with the indicator plate 12 at one end. When the motor 4 starts, the drive rod 5 rotates the wheel 6, which periodically presses against the piston 7. When the wheel 6 leaves the piston 7, the springs 8 push the piston 7 back to its original position within the housing 2. Compressed air then inflates the rubber sleeve 10 through the pipes 9, gently tapping the indicator plate 12. This vibration cleaning method avoids water washing residue and replaces traditional brush cleaning, reducing dust and preventing coating scratches, ensuring the indicator plate 12 remains clear and visible for a long time.

[0018] In this embodiment, a battery 13 is fixedly connected to the cover 3, which is used to power the motor 4. A cover 14 is fixedly connected to the cover 3, which can protect the battery 13 and the cover 3 to a certain extent. The battery 13 and the cover 3 are placed inside the cover 14. The indicator board 12 is placed correspondingly to the two rubber sleeves 10, ensuring that the two rubber sleeves 10 are detached from the indicator board 12. A rubber pad 15 is fixedly connected to the contact point between the cover 3 and the box 2 to prevent gas leakage inside the box 2. Multiple reinforcing ribs are fixedly connected to the connection point between the frame 11 and the base plate 1 to increase the strength of the frame 11. The frame 11 is fixedly connected to the indicator board 12 by bolts. The box 2 and the cover 3 are fixedly connected by bolts for easy disassembly and assembly for maintenance operations.

[0019] The working principle of this embodiment is as follows: During use, the motor 4 is connected to the battery 13 and an external drive device. The motor 4 drives the rod 5 to rotate the wheel 6 at a constant speed. The wheel 6 contacts the piston 7 once for each rotation. At the moment the wheel 6 leaves the piston 7, the force of the spring 8 pushes the piston 7 to move rapidly inside the housing 2, compressing the airflow in the housing 2 and delivering it to the pipe 9. This causes the rubber sleeve 10 to inflate briefly and lightly press against the surface of the warning board 12, causing the attached dust to fall off through vibration. This process avoids the problem of residual water forming stubborn stains in traditional water washing methods. The flexible rubber sleeve 10 replaces the hard brush, reducing dust and preventing scratches on the warning coating. At the same time, the cover 14 above the motor 4 continuously provides protection, blocking falling gravel and debris in the construction environment and preventing them from directly impacting the motor 4. This ensures the stable operation of the motor 4 and provides reliable power support for the entire cleaning process, thereby achieving efficient cleaning and long-term clear display of the warning board 12.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
