Description

Technical Field

[0001] The invention relates to a bridge ballast retaining block replacement process and equipment. Background Art

[0002] The existing ballast blocks of many bridges on the Shuohuang Line and Huangwan Line have been in service for a long time. Most of them are damaged, broken, and exposed. In addition, due to the continuous increase in the traffic volume of the Shuohuang Line and Huangwan Line, the lines have been changed to seamless lines, and the line has been raised and the ballast shoulders have been widened. The height of the ballast blocks on the entire bridge is insufficient. In order to ensure driving and personal safety, the ballast blocks are replaced to ensure the stability of the ballast on the bridge. The estimated replacement length of the bridge alone is 5362 single-line meters, and a total of 3365.58m of rubber ballast blocks are replaced. 2 , demolition masonry 184.09m 3 .

[0003] The existing solution is that the dismantled ballast retaining blocks and other waste materials should be transported to the designated location by the construction unit. It is strictly forbidden to abandon them at will to pollute the environment and prevent ballast leakage. It adopts a simple and reasonable L-shaped structure to facilitate production and installation. The new replacement ballast retaining blocks use rubber ballast retaining blocks.

[0004] The ballast retaining blocks in the prior art generally use L-shaped rubber ballast retaining blocks, with a steel frame built into the rubber plate, and the thickness of the rubber plate is 50mm; the dimensions of the ballast retaining blocks on the inside of a straight bridge or a curved bridge are: the vertical wall height is 350mm, and the bottom plate length is 200mm; the dimensions of the ballast retaining blocks on the outside of a curved bridge are: the vertical wall height is 500mm, and the bottom plate length is 250mm. The outer edge of the vertical wall of the L-shaped ballast retaining block is aligned with the ballast retaining wall. The ballast retaining blocks are overlapped and connected, and the overlap length is 4cm.

[0005] The existing process for replacing bridge ballast blocks is as follows: remove the ballast within 0.5m of the ballast blocks, dismantle the existing ballast blocks, and expose the existing bridge ballast walls. Clean the top surface of the ballast wall to make it flat and clean; use epoxy resin glue to install rubber ballast blocks; backfill the ballast and compact it. The road can only be opened to traffic after the ballast is backfilled. It generally requires manual work, resulting in high labor intensity. When encountering extreme weather such as rainy season and hot summer, it will cause work to stop, especially when it involves the replacement and transportation of a large number of ballast and ballast blocks, which takes a lot of time and delays the construction period. How to improve the automation of operations, reduce the extension of auxiliary time caused by turnover materials, and reduce the amount of manual work has become a technical problem that needs to be solved urgently.

[0138] The bridge ballast block replacement process of this embodiment includes the replacement device 4 of claim 1; the specific steps are as follows;

[0139] Step 1: First, the replacement device 4 of claim 1 is driven to the track of the ballast block 2 to be replaced; then, the ballast assembly 8 is cleaned and a ditch is opened manually at the beginning of the ballast block 2 to be repaired, so that the ballast block 2 is exposed;

[0140] Step 2, first, adjust the lifting and translation support 12 so that the front shovel head 20 sinks into the trench; the bottom plate of the front shovel support frame 21 contacts the upper surface of the ballast block 2 in the trench; then, start the linear reciprocating drive unit 23, so that the movable shovel 22 reciprocates on the bottom plate of the front shovel support frame 21, thereby shoveling and collecting the ballast in the trench; secondly, the transverse baffle 52 on the rising conveyor belt 13 enters the movable shovel 22, and the collected ballast is raised and output to the upper output guide frame 14; thirdly, the ballast falls from the upper output guide frame 14 to the vibrating screening assembly 15, and under the vibration of the inclined vibrating screen plate 25, the ballast with an appearance smaller than the screen hole of the vibrating screening assembly 15 falls and is separated, and under the guidance of the side guide plate 26, the ballast with an appearance larger than the screen hole falls onto the secondary conveyor belt 16;

[0141] Step 3: After the ballast at the trench is cleaned for a set distance, the equipment is replaced and moved forward, and the ballast retaining block 2 exposed after the ballast is cleaned is taken out from the trench;

[0142] Step 4: Place the new L-shaped ballast retaining member 27 at the trenching position and position it;

[0143] Step five: the ballast on the secondary conveyor belt 16 falls onto the output guide frame 17 and the falling channel 18 and falls onto the L-shaped ballast retaining member 27 for covering.

[0144] In step three, the ballast retaining block 2 is taken out from the trench manually or by a robot and placed in the old parts storage frame 50, and the remaining debris is cleaned;

[0145] In step 4, first, a number of L-shaped ballast retaining members 27 are placed in the storage channel 34 and separated by the spacer pads 29, and the bottom layer of L-shaped ballast retaining members 27 is carried by the extended lower support plate B49; then, the indexing assembly 35 is started, and the indexing power shaft 42 is rotated forward and reversed, so that the H-shaped swing frame 43 swings left and right, and the upper swing shaft 45 and the lower swing shaft 46 are guided by the corresponding U-shaped opening 44 and the horizontal guide groove 48, so that the lower support plate B49 and the upper support plate A47 alternately come to and leave the bottom layer of the L-shaped ballast retaining member 27, and at the same time, the stacked L-shaped ballast retaining members 27 are realized in the storage channel. The L-shaped ballast stopper 27 is dropped from the channel 34 to achieve the lowest layer of the L-shaped ballast stopper 27 on the bottom support plate 30. The next L-shaped ballast stopper 27 carried by the upper support plate A47 avoids the epoxy resin glue-coated part through the process opening 52 and drops to the lower support plate B49 to become the lowest layer of the L-shaped ballast stopper 27. Secondly, on the bottom support plate 30, the auxiliary push-out plate 36 pushes the dropped L-shaped ballast stopper 27 horizontally to the drop channel 39, and the L-shaped ballast stopper 27 falls into the open groove. At the same time, the auxiliary material coating part 37 coats the epoxy resin glue on the lower surface of the L-shaped ballast stopper 27 carried by the lower support plate B49.

[0146] Step 4: When the L-shaped ballast retaining member 27 falls into the trench, the side positioning assembly 10 is started to rotate, and the L-shaped ballast retaining member 27 is moved longitudinally so that the L-shaped ballast retaining member 27 is matched through the matching opening 28;

[0147] In step 5, as the replacement device 4 moves forward, the rear paddle 19 pushes the falling ballast 3 forward, so that the ballast 3 is paved flat;

[0148] After step five, compact the replacement area with a compacting hammer.

[0149] As a specific detail improvement, for the existing railway bridge 1, for the ballast block part 2 that needs to be replaced, the ballast 3 is collected, cleaned, screened, and backfilled. The replacement equipment 4 realizes mechanized operation replacement, which greatly reduces the workload. The pressure is reduced by the front car body 5, thereby reducing the impact of the replacement process on the track. The middle sinking connector 6, part of which may not be equipped with wheels, and the rear car body 7 is used as the load-bearing part to complete the main operation. The length of the car body is used to complete the circulation of ballast and the replacement of ballast blocks through time difference. The cleaning of the ballast stone assembly 8 realizes the circulation of ballast particles. The present invention has mentioned the main part, and it also has a new ballast particle adding and supplementing part, as well as a quantitative falling part. The new block falling assembly Component 9 realizes the installation of the ballast block, the side positioning component 10 cleverly uses rotation to realize the lateral push of the ballast block, the inclination of the rising conveyor belt 13 is realized through the hinged bracket 11 and the lifting and translation bracket 12, and the collection of ballast is realized through the upper output guide frame 14.
