Description

Technical Field

[0001] The utility model relates to the technical field of arch frame sliding devices, in particular to a Bailey steel arch frame sliding device. Background Art

[0002] In the construction of reinforced concrete box arch bridges with a span of 100-200m, the use of Bailey steel arch frame horizontal sliding formwork is a brand-new process technology. One of the conventional methods for new concrete box arch bridges is to set up temporary Bailey steel arch frames across the river bank as a support system for the concrete box arch casting formwork. For multi-span bridges with many lanes, multiple temporary Bailey steel arches need to be set up at one time, which has high measures costs and a long construction period. The second conventional method is to set up a full-span frame on the riverbed when conditions permit, which not only requires cutting off the flow, but also has higher construction measures costs. The use of the process technology of sliding the Bailey steel arch frame horizontally is an innovative method. The process technology and construction system effectively overcome the defects of high measures costs and long construction periods of previous conventional methods.

[0003] When the Bailey steel arch is sliding horizontally, no one must be near the slide rail. This is because during the sliding process, the Bailey steel arch may encounter accidents due to various reasons (such as uneven load, sliding equipment failure, uneven slide rail, etc.), such as sudden acceleration, deceleration or deviation from the slide rail, which may cause serious harm to nearby personnel. When performing translation, all obstacles on the slide rail, including tools, debris, dust, etc., need to be thoroughly cleared to ensure the flatness and smoothness of the slide rail. However, in order to accurately control and move smoothly, the movement is often slow. During the movement, the slide rail is easily contaminated with dust again. When operating in mountainous areas, rocks are prone to fall on the slide rail, thereby reducing the stability and safety of the arch during translation. Summary of the invention

[0004] The utility model aims to solve the problems existing in the background technology and proposes a Bailey steel arch frame sliding device which can temporarily clean and lubricate the slide rail when the supply frame is moving.

[0005] The technical solution of the utility model is: a Bailey steel arch frame sliding device, including two slide rails, and also including

[0006] Two driving mechanisms slidably mounted on the slide rail, the driving mechanisms comprising a driving block and a supporting block slidably mounted on the slide rail, the driving block being provided with a limit assembly, the limit assembly controlling whether the driving block can slide on the slide rail, an arch frame being fixedly mounted on the four supporting blocks, and the driving mechanism driving the arch frame to move on the slide rail;

[0007] A cleaning mechanism is installed on the support block and is slidably connected to the slide rail. The cleaning mechanism clears obstacles on the slide rail and lubricates the slide rail.

[0008] Optionally, the driving mechanism further comprises a hydraulic rod rotatably mounted on the driving block, and the other end of the hydraulic rod is rotatably connected to the supporting block.

[0009] Optionally, the limiting assembly includes a plurality of first limiting blocks fixedly mounted on the slide rail, an electric push rod fixedly mounted on both sides of the support block, and a second limiting block fixedly mounted on the telescopic shaft of the electric push rod.

[0010] Optionally, the cleaning mechanism includes a telescopic rod fixedly mounted on both sides of the support block, a cleaning plate fixedly mounted on the telescopic rod, a spring fixedly mounted on the cleaning plate and fixedly connected to the support block, a first motor fixedly mounted on both sides of the cleaning plate, a first connecting block height-mounted on the output shaft of the first motor, a plurality of first brushes fixedly mounted on the first connecting block, a second motor fixedly mounted on the cleaning plate, a second connecting block fixedly mounted on the output shaft of the second motor, and a plurality of second brushes fixedly mounted on the second connecting block.

[0011] Optionally, an obstacle warning component is also included, which is installed between the support block and the cleaning plate, and the obstacle warning component sends an alarm when the cleaning plate encounters resistance and cannot move.

[0012] Optionally, the obstacle warning component includes an alarm button fixedly mounted on the support block and an alarm strip fixedly mounted on the cleaning plate, wherein the alarm strip is located on one side of the alarm button and can contact the alarm button.

[0013] Optionally, the first connecting block and the second connecting block are both hollow structures, lubricating oil is provided in the first connecting block and the second connecting block, the first brush is in contact with the hydraulic oil in the first connecting block, and the second brush is in contact with the lubricating oil in the second connecting block.

[0014] Compared with the prior art, the utility model has the following beneficial technical effects:

[0015] The first motor drives the first brush to rotate, so that the first brush cleans the inside of the slide rail to prevent the inside of the slide rail from being contaminated with dust. The second motor drives the second brush to rotate, so that the second brush cleans the surface of the slide rail and can sweep away obstacles on the slide rail, thereby improving the stability and safety of the arch frame when moving, and preventing the slide rail from being contaminated with dust again during the slow movement of the arch frame.

[0016] Furthermore, through the contact between the lubricating oil and the first brush and the second brush, the capillary action causes the lubricating oil to be sucked into the hairs of the first brush and the second brush. Thus, the lubricating oil is evenly distributed on the entire surface of the first brush and the second brush. Thus, the first brush and the second brush can evenly lubricate the slide rail to reduce the friction resistance of the arch frame during the sliding process;

[0017] Furthermore, when an uncleanable obstacle appears on the slide rail, the obstacle will exert resistance on the cleaning plate, making it impossible for the cleaning plate to move. At this time, the movement of the support block will compress the spring and move the support block toward the cleaning plate, so that the alarm button contacts the alarm bar. After the alarm button is pressed, an alarm will sound, so that the operator can receive the alarm information in time and stop the support block from moving, thus avoiding the occurrence of dangerous accidents.

DETAILED DESCRIPTION

[0024] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example

[0026] like Figure 1-2As shown, the Bailey steel arch frame sliding device proposed by the utility model includes two slide rails 1, and also includes two driving mechanisms slidably installed on the slide rails 1, the driving mechanism includes a driving block 2 and a support block 201 slidably installed on the slide rails 1, and the driving mechanism also includes a hydraulic rod 202 rotatably installed on the driving block 2, and the other end of the hydraulic rod 202 is rotatably connected to the support block 201. The four support blocks 201 are fixedly installed with arch frames 4, and the driving mechanism drives the arch frames 4 to move on the slide rails 1. When the driving block 2 cannot move to the left on the slide rail 1, the hydraulic rod 202 is extended at this time, and the hydraulic rod 202 can push the support block 201 to move to the right, thereby driving the arch frame 4 to move to the right, thereby driving the arch frame 4 to move. When the hydraulic rod 202 is extended to the limit position, the hydraulic rod 202 is retracted. At this time, under the action of the gravity of the arch frame 4, there will be damping between the support block 201 and the slide rail 1, so that the support block 201 remains stationary on the slide rail 1. At this time, the hydraulic rod 202 drives the driving block 2 to move to the right along the slide rail 1, and then the hydraulic rod 202 is extended again to drive the support block 201 to move to the right again. Repeating this process can drive the arch frame 4 to move along the slide rail 1.

[0027] like Figure 1-2 and Figure 5 As shown, a limit assembly is provided on the driving block 2, and the limit assembly controls whether the driving block 2 can slide on the slide rail 1. The limit assembly includes a plurality of first limit blocks 3 fixedly mounted on the slide rail 1, electric push rods 301 fixedly mounted on both sides of the support block 201, and second limit blocks 302 fixedly mounted on the telescopic shaft of the electric push rod 301. When the telescopic shaft of the electric push rod 301 drives the second limit block 302 to descend, the second limit block 302 can be moved to one side of the first limit block 3. At this time, when the driving block 2 moves to the left, it will drive the second limit block 302 to move to the left, and the first limit block 3 will block the second limit block 302 from moving to the left, thereby preventing the driving block 2 from moving to the left, so that the hydraulic rod 202 can push the support block 201 to move to the right. When the hydraulic rod 202 is extended to the limit position, the hydraulic When the pressure rod 202 contracts, the electric push rod 301 drives the second limit block 302 to rise, and under the action of the hydraulic rod 202, the second limit block 302 moves to the right side of another first limit block 3 located on the right side of this first limit block, and then the electric push rod 301 drives the second limit block 302 to move downward again, so that the first limit block 3 can limit the second limit block again, thereby realizing continuous feeding of the support block 201, and then being able to continuously drive the support block 201 to move along the slide rail 1.

[0028] like Figure 3-4As shown, a cleaning mechanism is installed on the support block 201 and is slidably connected to the slide rail 1, and the cleaning mechanism removes obstacles on the slide rail 1 and lubricates the slide rail 1. The cleaning mechanism includes a telescopic rod 5 fixedly installed on both sides of the support block 201, a cleaning plate 501 fixedly installed on the telescopic rod 5, a spring 502 fixedly installed on the cleaning plate 501 and fixedly connected to the support block 201, a first motor 503 fixedly installed on both sides of the cleaning plate 501, a first connecting block 504 highly installed on the output shaft of the first motor 503, a plurality of first brushes 505 fixedly installed on the first connecting block 504, a second motor 506 fixedly installed on the cleaning plate 501, a second connecting block 507 fixedly installed on the output shaft of the second motor 506, and a plurality of second brushes 508 fixedly installed on the second connecting block 507. The cleaning plate 501 will move with the movement of the supporting block 201. When the cleaning plate 501 moves, the first motor 503 is started to drive the first connecting block 504 to rotate, and then the first brush 505 is driven to rotate, so that the first brush 505 cleans the inside of the slide rail 1 to prevent the inside of the slide rail 1 from being contaminated with dust, and the second motor 506 is started to drive the second connecting block 507 to rotate, and then the second brush 508 is driven to rotate, so that the second brush cleans the surface of the slide rail 1 and can sweep away obstacles on the slide rail 1 (such as stones, fallen leaves), thereby improving the stability and safety of the arch frame 4 during movement.

[0029] The first connection block 504 and the second connection block 507 are both hollow structures, and lubricating oil is provided in the first connection block 504 and the second connection block 507. The first brush 505 contacts the hydraulic oil in the first connection block 504, and the second brush 508 contacts the lubricating oil in the second connection block 507. When the lubricating oil contacts the first brush 505 and the second brush 508, due to the fine pipe structure of the first brush 505 and the second brush 508, the capillary action causes the lubricating oil to be sucked into the hairs of the first brush 505 and the second brush 508. This is because there is a certain attraction between the lubricating oil and the hairs of the first brush 505 and the second brush 508, and the cohesive force between the hairs causes the lubricating oil to rise along the hairs. The force of the capillary action is sufficient to make the lubricating oil penetrate into every corner of the first brush 505 and the second brush 508, so that the lubricating oil is evenly distributed on the entire surface of the first brush 505 and the second brush 508. Thereby, the first brush 505 and the second brush 508 can evenly lubricate the slide rail 1 to reduce the friction resistance of the arch frame 4 during the sliding process.

[0030] like Figure 3-4As shown, the slide rail 1 also includes an obstacle warning component, which is installed between the support block 201 and the cleaning plate 501. The obstacle warning component alarms when the cleaning plate 501 is unable to move due to resistance. The obstacle warning component includes an alarm button 509 fixedly installed on the support block 201 and an alarm bar 510 fixedly installed on the cleaning plate 501. The alarm bar 510 is located on one side of the alarm button and can contact the alarm button 509. When an obstacle that cannot be cleaned appears on the slide rail 1, the obstacle will apply resistance to the cleaning plate 501, so that the cleaning plate 501 cannot move. At this time, the movement of the support block 201 will compress the spring 502 and move the support block 201 in a direction close to the cleaning plate 501, so that the alarm button 509 contacts the alarm bar 510. After the alarm button 509 is pressed, an alarm will be sounded (the alarm device is a prior art and will not be described again), so that the operator can receive the alarm information in time and stop the support block 201 from moving, thereby avoiding the occurrence of dangerous accidents.

[0031] Working principle: The telescopic shaft of the electric push rod 301 drives the second limit block 302 to descend, so that the second limit block 302 can be moved to one side of the first limit block 3. At this time, when the driving block 2 moves to the left, it will drive the second limit block 302 to move to the left, and the first limit block 3 will block the second limit block 302 from moving to the left, thereby making it impossible for the driving block 2 to move to the left. The hydraulic rod 202 extends, and the hydraulic rod 202 can push the support block 201 to move to the right, thereby driving the arch frame 4 to move to the right. When the hydraulic rod 202 extends to the limit position, the hydraulic rod 202 is retracted. At this time, under the action of gravity of the arch frame 4, the support block 2 There is damping between 01 and the slide rail 1, so that the support block 201 remains stationary on the slide rail 1, and the electric push rod 301 drives the second limit block 302 to rise. At this time, the hydraulic rod 202 drives the drive block 2 to move to the right along the slide rail 1, so that the second limit block 302 moves to the right side of another first limit block 3 located on the right side of this first limit block, and then the electric push rod 301 drives the second limit block 302 to move down again, so that the first limit block 3 can limit the second limit block again, and then the hydraulic rod 202 is extended again to drive the support block 201 to move to the right again, and repeat this process to drive the arch frame 4 to move along the slide rail 1.

[0032] Start the first motor 503 to drive the first connecting block 504 to rotate, and then drive the first brush 505 to rotate, so that the first brush 505 cleans the inside of the slide rail 1 to prevent the inside of the slide rail 1 from being contaminated with dust, and start the second motor 506 to drive the second connecting block 507 to rotate, and then drive the second brush 508 to rotate, so that the second brush cleans the surface of the slide rail 1 and can sweep away obstacles (such as stones, fallen leaves) on the slide rail 1, thereby improving the stability and safety of the arch frame 4 during movement.

[0033] When an uncleanable obstacle appears on the slide rail 1, the obstacle will exert resistance on the cleaning plate 501, thereby preventing the cleaning plate 501 from moving. At this time, the movement of the support block 201 will compress the spring 502 and move the support block 201 toward the cleaning plate 501, thereby making the alarm button 509 contact the alarm bar 510. After the alarm button 509 is pressed, an alarm will be sounded (the alarm device is a prior art and will not be described in detail again), so that the operator can receive the alarm information in time and stop the support block 201 from moving, thereby avoiding the occurrence of dangerous accidents.

Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
