Description

Transportation system and transportation method for bridge sections

Technical Field

The invention relates to the technical field of bridge construction, in particular to a transportation system and a transportation method of bridge sections.

Background

In the splicing construction process of a large-tonnage bridge, the skid shoes are indispensable tools for transporting bridge sections forming a bridge body. In the process of transporting bridge sections, sliding shoes need to be placed on a slideway for transportation after penetrating through steel strands for guiding, then the bridge sections are moved to the sliding shoes, the steel strands are pulled to generate displacement through a hydraulic driving device, and then the sliding shoes can drive a bridge to move on the slideway, and the mass of the transported bridge sections is very large, so that the method driven by the sliding shoes is a relatively universal method in the field of bridge construction.

The traditional sliding shoe moving mode is mainly one-way moving, the direction can not be changed when a pier or other obstacles are met, so that the transportation is difficult, and the sliding shoes are connected in a mode of penetrating through steel strands or in a flexible connection mode. Lead to wearing steel strand wires can make steel strand wires atress uneven, and the jack is easy by the jamming in succession, and has the safety risk that the sliding shoe pulled away. When the front and rear sliding shoes are in flexible connection (the flexible connection means that a connecting piece is stressed only when being greatly deformed, such as a steel strand, and long finish rolling deformed steel bars (large self deflection) and the like) which are horizontally arranged, the friction force is inconsistent (if the front sliding shoe meets a small bulge on a slide way, and the slide way below the rear sliding shoe is very flat, the friction force of the front and rear sliding shoes is inconsistent, when the difference value of the friction force is very large, the front and rear sliding shoes can relatively displace.

Alternatively, two connecting rods are symmetrically arranged about the sliding shoe 2, and such a symmetrical arrangement can make the connection of the two sliding shoes 2 more stable, if only a single connecting rod or two connecting rods are used to connect the two sliding shoes 2 in an asymmetrical manner, such that the sliding shoe 2 located at the front can be shifted on the slideway due to unbalanced force when pulling the sliding shoe 2 located at the rear, which affects the carrying process. The hydraulic driving part 41 involved in the invention can be a continuous jack commonly used in bridge construction, the slide way in the invention comprises a transverse slide way and a longitudinal slide way, and the hydraulic driving part can effectively bypass each pier 9 in the middle in the transportation process, as shown in fig. 3, the transportation is more flexible and efficient.

In this embodiment, referring to fig. 4 and 8, the sliding shoe 2 includes a box body, the box body is a square structure, four corners are arranged at the bottom of the box body, and a notch 22 is arranged on each corner. When the box body is placed in the slide way, the matching accuracy of the box body is required to be ensured to be sufficient, so that the box body can smoothly slide on the slide way, but the flatness and the verticality of the general slide way cannot reach the corresponding accuracy due to processing defects, abrasion and the like, the box body can not be smoothly placed in the slide way, even one side or two sides of the general slide way are clamped and stagnated, so that the whole sliding shoe 2 structure is deviated in the advancing process to cause serious consequences, the box body is of a square structure, notches 22 are formed in four corners of the bottom of the box body, the matching size of the box body and the slide way can be subjected to certain transition compensation due to the notches 22 when the box body is placed in the slide way, the matching compatibility of the sliding shoe 2 structure and the slide way can be better met, the sliding shoe 2 can be effectively prevented from deviating on the slide way, and the construction efficiency can be better improved.

In this embodiment, referring to fig. 1, fig. 2, fig. 4, fig. 7 to fig. 9, the box body includes four side plates 23, at least two adjacent side plates 23 are provided with support lugs 21 on outer side walls thereof, the support lugs 21 provided between the adjacent side plates are staggered in position, and the support lugs are provided with rotation holes 211 which can be rotatably matched with the first rotation shaft and the second rotation shaft; the reason why the positions of the lugs 21 provided between the adjacent side plates 23 are shifted from each other is to prevent interference between the positions of the tie bars and the positions of the lugs 21 on the adjacent sides having the same height when the tie bars on one side are mounted. The conventional skid shoe structure is provided with the support lug 21 only on one side plate 23, so that the whole skid shoe structure is required to be correspondingly steered when steering is carried out, the weight of the skid shoe structure is very large, steering is difficult, and extra power is required to be consumed to realize steering, so that the problem that the whole skid shoe needs to be steered when the conventional skid shoe is reversed on a slideway is solved by the design mode, and the transportation efficiency of the bridge section is further improved. First mounting through holes 231 are formed in the two side plates 23 in the longitudinal direction, and the steel strand 42 on the longitudinal slide passes through the first mounting through holes 231 and is fixedly connected with the box body; and two lateral plates 23 are provided with second mounting through holes 232, and the steel strands 42 on the transverse slide pass through the second mounting through holes 232 and are fixedly connected with the box body. After passing through the first mounting through hole 231 or the second mounting through hole 232, the steel strand 42 may be fixedly connected to the box body by riveting or other connection methods, so as to stretch the steel strand 42 and drive the box body to slide on the slideway.

In this embodiment, referring to fig. 4-6, a bearing plate 24 is disposed on the top of the box body, and the bearing plate 24 is used for placing the bridge segment; the bottom of the box body is provided with an abrasion-resistant plate 25, the abrasion-resistant plate 25 is made of MGB engineering plastic alloy, and chamfers 251 are arranged on bottom edges of the abrasion-resistant plate 25 on the front side and the rear side in the transverse direction and the longitudinal direction; the sliding shoe 2 further comprises a fixing plate 26 disposed on one side or both sides in the longitudinal direction and the transverse direction, an upper end of the fixing plate 26 is fixed to the box body, and a lower end of the fixing plate 26 is used for blocking the wear-resisting plate 25. The bearing plate 24 can be integrally formed with the box body as a top cover of the box body, the bearing plate 24 and the box body can also be two separate parts, and the bearing plate 24 is fixedly connected to the upper position of the top cover of the box body. Because the box body slides on the slide way for a long time on the premise of bearing heavy objects, the wear-resisting plate 25 needs to be arranged at the bottom of the box body to meet the requirement of long-term wear, and the wear-resisting plate 25 is made of MGB engineering plastic alloy, so that the wear-resisting plate 25 has good heavy load bearing performance and impact resistance and is suitable for translation and sliding of oversized and huge heavy objects; meanwhile, the wear plate 25 has excellent wear resistance due to its low friction coefficient, and can slide smoothly on the slideway under the premise of bearing heavy pressure. If the wear plate 25 slides on the slideway with a high or large obstacle in the sliding direction, the wear plate 25 may directly block at the corresponding obstacle if the design of the chamfer 251 is not adopted, and by the design processed by the chamfer 251, the wear plate 25 can better surmount the obstacle when contacting the obstacle through the transition of the chamfer 251 so as to make the displacement process of the sliding shoe 2 smoother. The fixing plate 26 can be fixed on the box body through a threaded connection or riveting or welding mode, the lower end of the fixing plate 26 can block the wear-resisting plate 25, and the sliding shoe 2 structure can bear the shearing stress of the sliding error of the corresponding displacement of the box body and the wear-resisting plate 25 during the translation.

In this embodiment, referring to fig. 10, the wear-resistant plate 25 may be embedded into the bottom of the box body to achieve the fixed connection therebetween, so that the wear-resistant plate 25 is less likely to fall off from the box body in such a matching manner, and the wear-resistant plate 25 is prevented from protruding outside and rubbing against the box body for a long time to deform.

In this embodiment, referring to fig. 5, a bottom surface of the wear plate 25 is provided with a resistance reduction groove group, the resistance reduction groove group includes a first resistance reduction groove 252 and a second resistance reduction groove 253, the first resistance reduction groove 252 and the second resistance reduction groove 253 are arranged in a staggered manner, a length direction of the first resistance reduction groove 252 is parallel to a longitudinal direction, a length direction of the second resistance reduction groove 253 is parallel to a transverse direction, the bottom surface of the wear plate 25 is divided into a plurality of sliding regions 254 by the first resistance reduction groove 252 and the second resistance reduction groove 253, each sliding region 254 is provided with a counter bore 255, a first mounting hole 256 is arranged in each counter bore 255, a second mounting hole is correspondingly arranged at the bottom of the box body, and the box body and the wear plate 25 are fixed by passing through the first mounting hole 256 and the second mounting hole through a connector. The length direction of the first drag reduction groove 252 is parallel to the longitudinal direction, and when the slipper 2 slides along the longitudinal direction, foreign matters on the slide way more smoothly enter the first drag reduction groove 252; the length direction of second drag reduction groove 253 is parallel with the transverse direction, when the smooth boots 2 when sliding along the transverse direction, the foreign matter on the slide gets into more smoothly inside the second drag reduction groove 253, therefore the condition of jamming appears when the drag reduction groove group that sets up can effectively avoid the smooth boots 2 slides on the slide. Because each of the sliding regions 254 is in direct sliding contact with a slideway, a counterbore 255 may be provided in each of the sliding regions 254, with the first mounting hole 256 being provided within the counterbore 255, in order to prevent the ends of the connectors protruding through the mounting holes from contacting the slideway and thereby preventing the sliding motion from being impeded when the housing and the wear plate 25 are connected by the connectors. Alternatively, the housing and the wear plate 25 may be connected by a threaded member or riveted or otherwise connected.

In this embodiment, referring to fig. 8, a first reinforcing member 271 and a second reinforcing member 272 are disposed inside the box body, two sides of the first reinforcing member 271 are respectively fixed to two opposite side plates 23 in the longitudinal direction, and two sides of the second reinforcing member 272 are respectively fixed to two opposite side plates 23 in the transverse direction. When the sliding shoe 2 slides along the longitudinal direction, the stress between the two opposite side plates 23 in the longitudinal direction is large, and the structure is easy to be unstable due to long-term pulling, so that the first reinforcing piece 271 arranged between the two opposite side plates 23 in the longitudinal direction can effectively enhance the structural rigidity and strength of the box body, and ensure the structural stability of the box body in a long-term carrying process; when the sliding shoe 2 slides along the transverse direction, the stress between the two opposite side plates 23 in the transverse direction is large, and the structure is easy to be unstable due to long-term pulling, so that the second reinforcing member 272 arranged between the two opposite side plates 23 in the transverse direction can effectively enhance the structural rigidity and strength of the box body, and ensure the structural stability of the box body in a long-term carrying process.
