Description

Technical Field

[0001] This invention relates to a mobile platform device for railway bridge maintenance and its usage method, belonging to the field of railway engineering auxiliary equipment. Background Technology

[0002] When repairing pedestrian railings on railway bridges, high-altitude operations are often required, posing significant safety hazards. However, traditional devices (such as suspended platforms) suffer from poor stability, inadequate fixation, and susceptibility to damage, often failing to meet the requirements.

[0003] Based on the above problems, we have developed a device that is simple to operate, low in cost, and can ensure personnel safety. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a mobile platform device for railway bridge maintenance, which ensures the longitudinal and lateral movement of personnel and solves the problems of low efficiency, high risk and low efficiency of the existing devices.

[0005] The technical solution adopted in this invention is:

[0006] A mobile platform device for railway bridge maintenance includes a longitudinal moving device, a lateral moving device, and a fixing device;

[0007] The fixing device includes four retaining rings, and the lateral moving device and the longitudinal moving device are fixed by the fixing device;

[0008] The longitudinal moving device includes a longitudinal pulley block, a longitudinal hand crank, a longitudinal operating platform, and a first fixed rod. The longitudinal operating platform is a cuboid frame structure with a support plate at the bottom, allowing the operator to stand on the support plate for operation. The first fixed rod is connected to the upper part of the longitudinal operating platform. The bottom pulley of the longitudinal pulley block is connected to the longitudinal hand crank, which controls the vertical displacement of the longitudinal pulley block, thus moving the moving platform device in the vertical direction.

[0009] The lateral movement device includes a lateral fixed frame, a second fixed rod, a lateral pulley block, a lateral bearing block, lateral sliding wheels, vertical auxiliary sliding wheels, and a lateral hand crank. The lateral fixed frame is a horizontally placed square frame structure. Two angle steel supports are connected to the lower center of the left and right side frames. The rear side of the lateral fixed frame is connected downwards to the second fixed rod at both ends, and the front side is connected downwards to angle steel limiting posts with vertical auxiliary sliding wheels at both ends. The two angle steel supports are arranged opposite each other to fix the connecting rods of the upper and middle pulleys of the longitudinal pulley block, ensuring that the longitudinal and lateral movement devices are connected and do not experience relative displacement. The angle steel limiting posts are used to connect to the railway bridge railing. A vertical auxiliary sliding wheel is located in the middle of the angle steel limiting post, which contacts the railway bridge railing for easy movement. The vertical auxiliary sliding wheel reduces the friction of the lateral sliding wheels and improves efficiency.

[0010] A transverse sliding wheel is provided on the outer side of one end of the transverse fixed frame. The two ends of the transverse sliding wheel are connected to the angle steel column and the angle steel limiting column through connecting plates. A transverse bearing assembly is provided on the outer side of the other end of the transverse fixed frame. The two ends of the transverse bearing assembly are connected to the angle steel column and the angle steel limiting column. A transverse pulley assembly is fixed in the middle of the transverse bearing assembly. The transverse pulley assembly includes a transverse sliding wheel, a transverse hand crank, a first sleeve, a second sleeve, and a transverse connecting rod. The first sleeve is fitted on one end of the transverse connecting rod, and the second sleeve is provided in the middle of the transverse connecting rod. The other end of the transverse connecting rod is connected to the transverse hand crank. The second sleeve can rotate on the transverse connecting rod. The belt connects the transverse sliding wheel and the second sleeve. Under the action of the transverse hand crank, the second sleeve moves left and right on the transverse connecting rod, thereby driving the transverse pulley assembly to move left and right, causing the entire mobile platform device to undergo transverse displacement.

[0011] Furthermore, the longitudinal pulley block includes three pulleys connected by a belt. The upper and middle pulleys are fixed to the transverse fixed frame, so that the longitudinal pulley block is located below the center of the transverse fixed frame, which facilitates the control of the movement of the entire device. The lower pulley is connected to the longitudinal hand crank through a longitudinal connecting rod and a third sleeve. The longitudinal connecting rod and the third sleeve are set perpendicularly. A connecting plate is vertically provided on the longitudinal connecting rod. The other end of the connecting plate is connected to the first fixed rod, connecting and fixing the longitudinal pulley block to the first fixed rod. Furthermore, the contact position between the connecting plate and the longitudinal connecting rod is an arc-shaped groove structure, which plays a certain limiting role for the longitudinal hand crank.

[0012] The operation method is as follows: manually operate the longitudinal hand crank to drive the longitudinal pulley assembly to rotate, thereby driving the longitudinal operating platform to move up and down.

[0013] Furthermore, the first fixing rod is connected to the longitudinal operating platform by welding.

[0014] Furthermore, the first fixed rod of the longitudinal moving device and the second fixed rod of the transverse moving device are fixed by retaining rings. The retaining rings are equipped with a locking structure. After the moving platform device reaches the appropriate position, the retaining rings are locked. There are a total of four retaining rings, which lock the upper and lower ends of the first and second fixed rods respectively.

[0015] Furthermore, the first sleeve is connected to the first fixed rod, specifically: the first fixed rod is provided with an arc-shaped connecting groove, and the first sleeve is fixed in the arc-shaped connecting groove, so that the position of the transverse pulley group in the vertical direction remains unchanged.

[0016] Furthermore, the connection method between the horizontal hand crank and the horizontal connecting rod is as follows: one end of the hand crank is screwed into the threaded end of the threaded hole of the part and presses against the recess of the connecting rod to fix the relative position of the two parts.

[0017] The operation is as follows: a horizontal hand crank is located at the bottom of a horizontal pulley block. The operator rotates the hand crank, causing the pulley block to rotate. The pulleys then move the horizontal bearing assembly horizontally, thereby moving the mobile platform device laterally. Furthermore, to prevent the hand crank from reversing, it is equipped with an automatic locking linkage shaft.

[0018] Furthermore, the horizontal fixing frame is connected to the second fixing rod by welding.

[0019] This invention provides a method for using the aforementioned mobile platform device during railway bridge maintenance, the specific process of which is as follows:

[0020] Step 1: Place the mobile platform device under the railing of the railway bridge;

[0021] Step 2: Fix the horizontal fixing frame of the mobile platform device to the railway bridge railing: the railing is secured by the angle steel limiting posts of the vertical auxiliary sliding wheels in the horizontal fixing frame;

[0022] Step 3: Check whether the horizontal fixing frame is securely fixed to the railway bridge railing;

[0023] Step 4: Maintenance personnel enter the operating platform;

[0024] Step 5: The maintenance personnel rotate the longitudinal hand crank in the longitudinal moving device to move the longitudinal pulley block, thereby moving the longitudinal operating platform in the vertical direction;

[0025] Step Six: The maintenance personnel rotate the horizontal hand crank in the horizontal moving device, which drives the horizontal sliding wheel and the horizontal bearing assembly. The rotation of the horizontal bearing assembly drives the vertical auxiliary sliding wheel, thereby moving the horizontal operating platform in the horizontal direction.

[0026] Step 7: When the maintenance personnel have completed the maintenance, they will move the operating platform upward by rotating the hand crank of the longitudinal movement device upward.

[0027] This invention connects to the railway bridge via a fixed frame and uses pulleys for movement, saving time in railway bridge maintenance, improving maintenance efficiency, ensuring the safety of workers, and reducing production costs.

[0028] The beneficial effects of this invention are:

[0029] This invention is used during the maintenance of pedestrian railings on railway bridges, which can significantly improve the safety and work efficiency of maintenance personnel. At the same time, the device has a simple structure, low cost, reliable operation, and requires no maintenance. Furthermore, the installation of this mobile platform device will greatly reduce the accident risk for maintenance personnel when working at heights, improve their work efficiency, and contribute to protecting the lives and property of personnel.

Detailed Implementation

[0043] The present invention will be further illustrated by the following embodiments, but is not limited to the following embodiments.

[0044] Example 1:

[0045] like Figures 1-12 As shown, a mobile platform device for railway bridge maintenance includes a longitudinal moving device, a lateral moving device, and a fixing device.

[0046] The fixing device includes four retaining rings 18, and the lateral moving device and the longitudinal moving device are fixed by the fixing device;

[0047] The longitudinal moving device includes a longitudinal pulley block 2, a longitudinal hand crank 3, a longitudinal operating platform 4, and a first fixed rod 5. The longitudinal operating platform 4 is a cuboid frame structure with a support plate at the bottom, allowing the operator to stand on the support plate for operation. The first fixed rod 5 is connected to the upper part of the longitudinal operating platform 4. The bottom pulley of the longitudinal pulley block 2 is connected to the longitudinal hand crank 3, which controls the vertical displacement of the longitudinal pulley block 2, thus moving the moving platform device in the vertical direction.

[0048] Specifically, the longitudinal pulley block includes three pulleys connected by a belt. The upper and middle pulleys are fixed on the transverse fixed frame, so that the longitudinal pulley block is located below the center of the transverse fixed frame, which facilitates the control of the movement of the entire device. The lower pulley is connected to the longitudinal hand crank 3 through the longitudinal connecting rod 13 and the third sleeve 14. The longitudinal connecting rod 13 and the third sleeve 14 are set perpendicularly. A connecting plate 17 is vertically provided on the longitudinal connecting rod 13. The other end of the connecting plate 17 is connected to the first fixed rod 5, connecting and fixing the longitudinal pulley block 2 to the first fixed rod 5. The contact position between the connecting plate 17 and the longitudinal connecting rod 13 is an arc-shaped groove structure, which plays a certain limiting role for the longitudinal hand crank.

[0049] The operation method is as follows: manually operate the longitudinal hand crank to drive the longitudinal pulley assembly to rotate, thereby driving the longitudinal operating platform to move up and down.

[0050] Furthermore, the first fixing rod 5 is connected to the longitudinal operating platform 4 by welding.

[0051] The lateral movement device includes a lateral fixed frame 6, a second fixed rod 7, a lateral pulley group 8, a lateral bearing group 9, a lateral sliding wheel 10, a vertical auxiliary sliding wheel 11, and a lateral hand crank 12;

[0052] The horizontal fixing frame 6 is a square frame structure placed horizontally, and two angle steel pillars 21 are connected to the bottom of the two opposite sides. The two ends of the rear side of the horizontal fixing frame 6 are respectively connected to the second fixing rod 7 downwards; the two ends of the front side are respectively connected to the angle steel limiting column 20 with vertical auxiliary sliding wheel 11 downwards.

[0053] The second fixing rod 7 of the horizontal fixing frame is fixed to the upper part of the first fixing rod 5 by a retaining ring 18. When the position needs to be adjusted, the retaining ring is loosened, and after the position is adjusted, the entire device is tightened by the retaining ring.

[0054] Two angle steel supports 21 are arranged opposite each other to fix (weld) the connecting rods of the upper and middle pulleys of the longitudinal pulley block 2, so that the longitudinal moving device and the lateral moving device are connected and do not have relative displacement.

[0055] Angle steel limiting posts 20 are used to connect railway bridge railings (two angle steels rest on the railway bridge railing). A vertical auxiliary sliding wheel 11 is provided in the middle of the angle steel limiting post 20. This vertical auxiliary sliding wheel contacts the railway bridge railing for easy movement. The vertical auxiliary sliding wheel reduces the friction of the horizontal sliding wheel, improving efficiency.

[0056] A transverse sliding wheel 10 is provided on the outer side of one end of the transverse fixed frame 6. The two ends of the transverse sliding wheel are connected to the angle steel column 20 and the angle steel limiting column 21 through connecting plates. A transverse bearing assembly 9 is provided on the outer side of the other end of the transverse fixed frame. The two ends of the transverse bearing assembly are connected to the angle steel column and the angle steel limiting column. A transverse sliding wheel of a transverse pulley assembly is fixed in the middle of the transverse bearing assembly 9. The transverse pulley assembly includes a transverse sliding wheel 10, a transverse hand crank 12, a first sleeve 15, a second sleeve 16, and a transverse connecting rod 19. The first sleeve 15 is sleeved on one end of the transverse connecting rod 19, and the second sleeve 16 is provided in the middle of the transverse connecting rod 19. The other end of the transverse connecting rod 19 is connected to the transverse hand crank 12. The second sleeve 16 can rotate on the transverse connecting rod 19. The belt connects the transverse sliding wheel 10 and the second sleeve 16. Under the action of the transverse hand crank 12, the second sleeve 16 moves left and right on the transverse connecting rod 19, thereby driving the transverse pulley assembly 8 to move left and right, so that the entire mobile platform device undergoes transverse displacement.

[0057] Specifically, the first sleeve 15 is connected to the first fixed rod 5, specifically: the first fixed rod 5 is provided with an arc-shaped connecting groove, and the first sleeve 15 is fixed in the arc-shaped connecting groove, so that the position of the transverse pulley group in the vertical direction remains unchanged.

[0058] Specifically, the horizontal hand crank 12 and the horizontal connecting rod 19 are connected by screwing one end of the hand crank into the threaded hole of the part and pressing against the recess of the connecting rod to fix the relative position of the two parts.

[0059] The operation is as follows: the horizontal hand crank 12 is located at the bottom of the horizontal pulley block 8. The operator rotates the horizontal hand crank to rotate the horizontal pulley block, which in turn drives the horizontal bearing block to move horizontally, thereby moving the mobile platform device laterally. Furthermore, to prevent the horizontal hand crank from reversing, it is equipped with an automatic locking linkage shaft.

[0060] Specifically, the first fixed rod 5 of the longitudinal moving device and the second fixed rod 7 of the transverse moving device are fixed by retaining rings 18. The retaining rings have a locking structure. After the moving platform device reaches the appropriate position, the retaining rings are locked. There are four retaining rings in total, which lock the upper and lower ends of the first and second fixed rods respectively.

[0061] Specifically, the horizontal fixing frame 6 is connected to the second fixing rod 7 by welding.

[0062] The specific implementation process of the mobile platform device used for the maintenance of the aforementioned railway bridge is as follows:

[0063] Step 1: Place the mobile platform device under the railing of the railway bridge;

[0064] Step 2: Fix the horizontal fixing frame of the mobile platform device to the railway bridge railing: the railing is secured by the angle steel limiting posts of the vertical auxiliary sliding wheels in the horizontal fixing frame;

[0065] Step 3: Check whether the horizontal fixing frame is securely fixed to the railway bridge railing;

[0066] Step 4: Maintenance personnel enter the operating platform;

[0067] Step 5: The maintenance personnel rotate the longitudinal hand crank in the longitudinal moving device to move the longitudinal pulley block, thereby moving the longitudinal operating platform in the vertical direction;

[0068] Step Six: The maintenance personnel rotate the horizontal hand crank in the horizontal moving device, which drives the horizontal sliding wheel and the horizontal bearing assembly. The rotation of the horizontal bearing assembly drives the vertical auxiliary sliding wheel, thereby moving the horizontal operating platform in the horizontal direction.

[0069] Step 7: When the maintenance personnel have completed the maintenance, they will move the operating platform upward by rotating the hand crank of the longitudinal movement device upward.

[0070] This device can significantly improve the safety and work efficiency of maintenance personnel. At the same time, the device has a simple structure, low cost, reliable operation, and requires no maintenance.
