Description

Technical Field

[0001] The present invention relates to the field of engineering maintenance, and particularly to a device for quickly peeling off rust from the steel structure coating of a railway station building. Background Art

[0002] At the present stage, steel structures are widely used in railway passenger stations in China because of their good mechanical properties, high bearing capacity, light self-weight, good seismic performance, easy factory production, short construction period, energy conservation and environmental protection. Corrosion and high temperature will have a great impact on the safe use of steel structures. Therefore, coating technology is used on the surface of steel structures for anti-corrosion and fire protection. However, the peeling off of the steel structure coating in railway passenger stations is a common phenomenon, and more than three thousand passenger stations in the railway industry will face this problem. The peeling off of the steel structure coating in passenger stations will not only cause corrosion of the steel structure, reduce the structural strength of the steel structure, but also affect the safety of pedestrians and trains. Therefore, it is necessary to repair the steel structure coating of railway passenger stations in a timely manner, especially the fireproof and anti-corrosion coating system of the steel columns in the station building. However, there is a lack of efficient equipment and technology for repairing the steel structure coating in railway passenger stations. At present, the repair of the steel structure coating mainly relies on manual climbing and manual rust removal, which is inefficient, has great potential safety hazards, and has high labor and material costs.

[0003] In order to eliminate the hidden danger of the peeling off of the steel structure coating in passenger stations and ensure the safety of high-speed rail operation and passenger travel, it is urgent to repair the steel structure coating in passenger stations. Due to the particularity of the railway industry, most of the repair work is carried out during the night skylight time. Therefore, it is necessary to quickly peel off the old coating and remove rust. Summary of the Invention

A pin shaft rotary pair is arranged at the side end of the first box body, and a pin shaft embedding groove is arranged at the side end of the second box body. The first box body and the second box body are locked and connected through the pin shaft rotary pair and the pin shaft embedding groove.

[0006] Among them, the first box body includes a first upper track, and the peeling mechanism is installed on the first upper track; a first lower track, and the rust removal mechanism is installed on the first lower track.

The fixed motor is connected to the driving wheel through a bracket, and the driving wheel is installed on the base of the climbing mechanism. The structure of the driving wheel is an aluminum hub in the core + an outer rubber coating + a deep groove ball bearing. The outer rubber-coated wheel surface of the driving wheel is a large arc Adjust the radial position along the long groove at the top of the base with the bracket to adapt to steel columns of different diameters;

[0010] Among them, the peeling mechanism includes a peeling device housing, a servo motor, and a peeling roller. Among them, the servo motor drives the peeling roller in a linkage manner, and the servo motor and the peeling roller are installed inside the peeling device housing.

[0012] Preferably, three sets of the climbing mechanism are evenly distributed at 120° within the annular device and surround the steel column. The single-wheel climbing force × 3 ≥ the weight of the whole set of equipment. In special cases, when the climbing mechanism fails, the stall sensor controls the climbing servo motor to stop.

[0025] The following combines the drawings and specific embodiments to describe in detail a rapid peeling and rust removal device for the steel structure coating of a railway station house provided by the present invention.

[0026] Figures 1-7 As shown, a rapid peeling and rust removal device for the steel structure coating of a railway station house, the device is generally an annular body, including a first box 1, a second box 2, a clamping mechanism 3, a climbing mechanism 4, a peeling mechanism 5 and a rust removal mechanism 6 are arranged inside the first box 1 and the second box 2. A pin shaft rotary pair 11 is arranged at the side end of the first box 1, a pin shaft insertion groove 21 is arranged at the side end of the second box 2, and the first box 1 and the second box 2 are locked and connected through the pin shaft rotary pair 11 and the pin shaft insertion groove 21.

[0027] The first box 1 includes a first upper track 12, on which the peeling mechanism 5 is installed; a first lower track 13, on which the rust removal mechanism 6 is installed, and a first fixed seat 14, on which the climbing mechanism 4 is installed.

[0028] The second box body 2 includes a second upper track 22 on which the peeling mechanism 5 is installed; a second lower track 23 on which the rust removal mechanism 6 is installed, and a second fixed seat 24 on which the climbing mechanism 4 is installed.

[0029] The climbing mechanism 4 includes a driving wheel 41. The fixed motor 42 is connected to the driving wheel 41 through a bracket 43, and the driving wheel 41 is installed on the climbing mechanism base 44.

[0030] The clamping mechanism 3 includes a clamping friction head 31, a hydraulic transmission device 32, and a clamping mechanism base 33. Among them, the hydraulic transmission device 32 drives the clamping friction head 31 in a linkage manner, and the hydraulic transmission device 32 is installed on the clamping mechanism base 33.

[0031] The peeling mechanism 5 includes a peeling device housing 51, a servo motor 52, and a peeling roller 53. Among them, the servo motor 52 drives the peeling roller 53 in a linkage manner, and the servo motor 52 and the peeling roller 53 are installed inside the peeling device housing 51.

[0032] The rust removal mechanism 6 includes a rust removal mechanism housing 61, a rust removal mechanism motor 62, and a rust removal grinding wheel 63. Among them, the rust removal mechanism motor 62 drives the rust removal grinding wheel 63 in a linkage manner, and the rust removal mechanism motor 62 and the rust removal grinding wheel 63 are installed inside the rust removal mechanism housing 61.

[0033] Three sets of the climbing mechanism 4 are evenly distributed at 120° in the annular body device, and three sets of the clamping mechanism 3 are evenly distributed at 120° in the annular body device.

[0034] There are multiple peeling mechanisms 5 and rust removal mechanisms 6.

[0035] During the implementation process,

[0036] Attach the first box body to the surface of the steel column. According to the distance between the driving wheel of the climbing mechanism and the surface of the steel column, adjust the position of the support to ensure that the surface of the driving wheel can closely adhere to the surface of the steel column; the operation of the second box body is the same as above. Finally, connect the first and second box bodies through the quick-install locking mechanism.

[0037] Turn on the power, and the rapid peeling and rust removal device starts to operate. The working principle is as Figure 8 shown. First, judge whether the current climbing mechanism is in contact with the surface of the steel column through the pressure sensor in the driving wheel of the climbing mechanism. If not, the rapid peeling and rust removal device automatically cuts off the power, and the operator checks the climbing mechanism; if so, the climbing mechanism operates and drives the peeling and rust removal device to climb upward. When it reaches the place where operation is required, the clamping mechanism clamps, and the peeling mechanism and the rust removal mechanism start to work simultaneously. After the two devices complete three laps of circular work around the axis respectively in the first and second box bodies, the operation stops. At this time, the clamping mechanism loosens, and the climbing mechanism operates to drive the peeling and rust removal device to continue climbing upward.

[0038] After completing the peeling and rust removal operations, the climbing mechanism runs in the reverse direction, driving the peeling and rust removal device to fall until the bottom, and then power off to remove the equipment.

[0039] Finally, it should be noted that the above embodiments are only used to describe the technical solution of the present invention rather than to limit the technical method. The present invention can be extended to other modifications, variations, applications and embodiments in application, and therefore it is considered that all such modifications, variations, applications and embodiments are within the scope of the present invention.
