Examples

For a higher bridge, a water collecting pipe is installed at a central separation position under the bridge, and an ultrahigh scaffold needs to be erected. The ultrahigh scaffold is high in erection difficulty and long in construction period, and the stability of the ultrahigh scaffold is the foundation of construction safety and has higher technical requirements on workers.

For the ultrahigh bridge, it is also very difficult to erect the ultrahigh scaffold, and the installation is difficult to complete.

This embodiment provides a catchment pipe installation auxiliary device under bridge, adopts this auxiliary device can conveniently accomplish the catchment pipe installation of central separation position under the bridge.

As shown in fig. 1, 2 and 3, the auxiliary device includes two suspension cables 100, a track frame 200 and a trolley 300.

The two suspension cables 100 are positioned at the central separation position under the bridge, and two ends of the two suspension cables 100 are respectively fixed on the piers at two sides. Fig. 1 and 2 show a pier and a deck B, where the center under bridge separation is located on the bottom surface of the bridge and between two beams C on the bottom surface of the bridge.

Two rows of piers are generally provided along both sides of the center of the bridge C, and thus, the two suspension cables 100 are connected to the two rows of piers, respectively.

The rail bracket 200 is installed on the two suspension cables 100, and a slide rail 220 is formed on the rail bracket 200.

The cart 300 is placed on the rail housing 200 and mounted to the slide rail 220 so that the cart 300 can move back and forth on the rail housing 200 along the slide rail 220.

The front-rear direction referred to herein is along the longitudinal direction of the bridge C, and the left-right direction referred to herein is along the width direction of the bridge C.

The two suspension cables 100 form flexible supports between piers, the track frame 200 is used as a rigid support, the track frame 200 is used for drawing the two suspension cables 100, the two suspension cables 100 support the track frame 200, and the two suspension cables 100 and the track frame are combined to form a temporary work platform under a bridge, so that the work platform is high in building speed.

The left side and the right side of the track frame 200 are simultaneously supported, and the track frame 200 is stable and not easy to turn over.

In addition, because the trolley 300 on the track frame 200 is positioned at a position separated from the center under the bridge, that is, the trolley 300 is positioned between the side vertical surfaces of the two beams C on the bottom surface of the bridge, the trolley 300 is matched with the vertical surfaces of the two beams C to further limit the whole overturn of the device, and the stability is improved.

Utilize this stable and have under-bridge catchment pipe construction auxiliary device of carrying capacity during the construction, the operation personnel can load pipeline D in dolly 300 to promote dolly 300 removal operation on this interim work platform, construction convenience, quick, the catchment pipe of solving central authorities' separation position is difficult to the problem of installation.

For further convenience of construction, both ends of the two suspension cables 100 are connected to the pier at both ends, respectively.

The bridge side piers are piers at two ends of the bridge C close to the shore and are also called bridge abutments; the pier A in the bridge is a pier between two bridge abutments.

When the suspension cable 100 is too long, the middle section of the suspension cable 100 is easy to loosen and droop, and in the prior art, in order to tension the suspension cable 100, a plurality of suspension points are generally arranged at the middle section of the suspension cable 100, the suspension cable 100 is hung under the bridge C, so that the track frame 200 cannot cross the suspension points, and when the next section is constructed, the track frame 200 must be disassembled, and then the track frame 200 must be reinstalled on the next section. In this way, the arrangement of the full length of the suspension cable 100 is meaningless.

In order to solve the technical problem, the auxiliary device for the water collecting pipe construction further comprises a tensioning device, and the tensioning device comprises a supporting wheel 500. The supporting wheel 500 is arranged on the side stop block of the pier A in the bridge, and the middle section of the suspension cable 100 passes through the supporting wheel 500.

The suspension cable 100 is connected to the pier at the two ends to form a full-length flexible support, and the bearing wheel 500 is supported at the middle section of the suspension cable 100 to tension the suspension cable 100, so that the stability is improved. When the next construction is required, the rail housing 200 is moved across the supporting wheels 500 along the suspension cable 100, so that the rail housing 200 can pass through the entire center-spaced portion under the bridge along the suspension cable 100.

In this embodiment, at least one supporting wheel 500 is disposed on the side stop of each pier a in the bridge.

The structure of the supporting wheel 500 is as shown in fig. 4, the base of the supporting wheel 500 is fixed on the edge stop block of the pier a in the bridge, the wheel body of the supporting wheel 500 is mounted on the base through a bearing, and the wheel shaft of each supporting wheel 500 is provided with a third groove 510.

The suspension cable 100 passes through the third groove 510, and the side wall of the third groove 510 prevents the suspension cable 100 from slipping right and left.

Under the bridge, because an environment for ventilation is often formed, the suspension cable 100 and the track frame 200 are easy to sway left and right when the wind is strong, and the aforementioned tensioning device further comprises a tying rope 700 for further tensioning the suspension cable 100. One end of the drawknot rope 700 is fixed to the pier body of the pier A in the bridge, and the other end of the drawknot rope 700 is connected with the suspension cable 100.

Under the action of the drawknot rope 700, the suspension cable 100 keeps close to the pier A adjacent to the suspension cable 100, and the suspension cable 100 can be limited to swing left and right to a certain extent, so that the overall stability of the device is further improved.

The rail holder 200 is configured to be slidable along the suspension cable 100, and the rail holder 200 is not detached from the suspension cable 100 when the suspension cable 100 swings left and right. A plurality of pulley blocks 210 are respectively arranged at both sides of the track frame 200, and the pulley blocks 210 at both sides are respectively connected to the corresponding suspension cables 100.

Fig. 5 and 6 show the structure of the pulley blocks 210, each pulley block 210 includes a first wheel 211 and a second wheel 212, the first wheel 211 is located above the suspension cable 100, the second wheel 212 is located below the suspension cable 100, and the first wheel 211 and the second wheel 212 cooperate to clamp the suspension cable 100. Under the clamping of the first wheel body 211 and the second wheel body 212, the track frame 200 is not easy to be separated from the suspension cable 100, and the overall stability of the temporary platform is high.

To further prevent the suspension cable 100 from being detached, the first wheel body 211 is formed with a first groove 2111 at its periphery, the second wheel body 212 is formed with a second groove 2121 at its periphery, and the first groove 2111 and the second groove 2121 are opposed to form a passage for allowing the suspension cable 100 to pass therethrough. The suspension wire 100 is embedded in the passage so that the suspension wire 100 does not get out of the pulley block 210 regardless of the swing and movement of the rail housing 200.

In one embodiment, the width of the third groove 510 of the supporting wheel 500 is larger than the widths of the first wheel body 211 and the second wheel body 212, so that at least the second wheel body 212 passes through the third groove 510 when the track frame 200 spans the pier a in the bridge, thereby ensuring that the suspension cable 100 is always aligned with the middle position of the third groove 510 to further prevent the suspension cable 100 from being separated from the supporting wheel 500.

In another embodiment, the width of the third groove 510 of the supporting wheel 500 is equal to the width of the first wheel body 211 and the second wheel body 212, and when the track frame 200 spans the pier a, the wheel circumference of the second wheel body 212 abuts against and fits the wheel circumference of the supporting wheel 500, so as to ensure that the suspension cable 100 is always aligned with the middle position of the third groove 510, and further prevent the suspension cable 100 from being separated from the supporting wheel 500.

To facilitate the mating of the periphery of the second wheel body 212 with the periphery of the support wheel 500, the periphery of the second wheel body 212 is formed with second gear teeth 2122 and the periphery of the support wheel 500 is formed with corresponding gear teeth, the gear teeth of the support wheel 500 being engaged with the second gear teeth 2122.

In order to keep the first wheel 211 and the second wheel 212 rotating synchronously, so that the friction force of the suspension cable 100 is consistent up and down, prevent the track frame 200 from tilting forward or backward, and improve the stability of the track frame 200, the first wheel 211 has a first gear tooth 2112 formed on the periphery thereof, and the first gear tooth 2112 is engaged with the second gear tooth 2122 to ensure that the first wheel 211 and the second wheel 212 rotate synchronously.

When the weight of the rail frame 200 is heavy, it is sometimes difficult for an operator to push the rail frame 200 to cross the pier a in the bridge, and to solve this technical problem, winches (not shown in the figure) are respectively fixedly provided on the pier at both ends.

For convenience of description, one of them is referred to as a first winch, and the other is referred to as a second winch.

The traction rope 800 of the first winch is connected with one end of the rail frame 200, and the traction rope 800 of the second winch is connected with the other end of the rail frame 200.

When the first winch unwinds, the second winch unwinds, and when the first winch winds, the second winch unwinds, and the first winch and the second winch are matched to move the rail frame 200 forward or backward along the suspension cable 100. Under the effect of two hoists, the operation personnel control two hoists synchronous working and can accomplish the track frame 200 and remove, use manpower sparingly, reduce the construction degree of difficulty.

In addition, when the pulley block 210 passes through the connection node between the knot rope 700 and the suspension cable 100, the knot rope 700 may generate resistance to the pulley block 210, and in order to prevent the resistance from being too large to pass through, the second wheel body 212 is elastically matched with the first wheel body 211.

Referring to fig. 5 and 6 again, a sleeve 213 is fixed on the track frame 200, a piston rod 214 is disposed in the sleeve 213, a spring 215 is sleeved on the piston rod 214, and two ends of the spring 215 are respectively connected to the sleeve 213 and the piston rod 214.

The rotating shaft of the first wheel 211 is mounted on the sleeve 213, the rotating shaft of the second wheel 212 is mounted on the piston rod 214, and the elastic force of the spring 215 pulls the second wheel 212 toward the first wheel 211, so that the first wheel 211 and the second wheel 212 are kept in close fit.

When the pulley block 210 passes through the connection node of the hitch rope 700 and the suspension cable 100, the second wheel body 212 is slightly moved downward by the compression of the hitch rope 700 to reduce the passing resistance, and the spring 215 is stretched. After the passage, the spring 215 returns to deform and contract, and the second wheel body 212 is attached to the first wheel body 211 again.

The first wheel body 211 and the second wheel body 212 are elastically matched, so that the track frame 200 can be initially installed on the suspension cable 100 before construction is facilitated.

In order to further prevent the trolley 300 from tipping over or falling off the rail frame 200 to the left and right, a fixing rope 400 is stretched between the two pier abutments, and the trolley 300 is connected to the fixing rope 400 through a slide hook 410 or other sliding connection. During construction, an operator can also pull the trolley 300 to move along the track frame 200 on the trolley 300 by climbing the fixing rope 400, thereby further facilitating construction.

In operation, the lanyard 400 also acts as a handle to help the operator stand steady. Meanwhile, after the body of the worker can be tightened by the safety rope, the other end of the safety rope is connected to the fixing rope 400 through the sliding hook 410, so that personal safety is further guaranteed.
