[0024] like Figure 1-3 As shown, the device of the utility model for installing a large-diameter drainage pipe along the bridge deck of a steel-concrete composite beam bridge comprises:

[0025] The trolley 1 is arranged between the road guardrail 16 and the sidewalk guardrail 17, and the moving direction is arranged along the bridge direction;

[0026] The lower tube guide frame 2 is arranged on the outer side of the side where the trolley 1 is arranged in the transverse direction of the bridge deck. The upper end of the lower tube guide frame 2 extends toward the trolley 1 and is fixedly connected to the upper end of the trolley 1. The lower end of the lower tube guide frame 2 extends downward to below the bottom of the bridge deck and then extends to the inner side of the bridge to the installation position of the drainage pipe 15. The upper end of the lower tube guide frame 2 is provided with a pulley structure 3 downward near the side of the bridge deck. A traction rope 4 is wound around the pulley structure 3. One end of the traction rope 4 is connected to the bridge deck traction equipment, and the other end is used to connect with the drainage pipe 15.

[0027] The trolley 1 has a certain load-bearing capacity and walking function. It is arranged between the lane guardrail 16 and the sidewalk guardrail 17 without occupying the driving channel. The trolley 1 is provided with a moving device 18. The specific structure can install wheels at the bottom. The wheels are connected to the motor by a transmission device. The motor is used to provide power for the trolley 1 to move, thereby driving the trolley 1 as a whole to move along the bridge direction. The frame rods of the lower tube guide frame 2 and the trolley 1 are respectively spliced ​​with 6cm×4cm square steel, which bear the connection between the lower tube guide frame 2 and the trolley 1 and the weight of the pulley structure 3 and the traction rope 4 for lifting the drainage pipe 15. Most of the overall structure of the trolley 1 is connected by welding. The lower tube guide frame 2 and the connection between the lower tube guide frame 2 and the trolley 1 are connected by high-strength bolts. The pulley structure 3 is generally set as a fixed pulley.

[0028] When using the device, place the trolley 1 in a fixed position between the lane guardrail 16 and the sidewalk guardrail 17, then install the lower pipe guide frame 2, use a crane to place the longitudinal main drainage pipe 15 in advance in the direction of travel of the device, adjust the placement of the drainage pipe 15 so that the drainage pipe 15 is placed under the pulley structure 3, the pulley structure is generally set as a fixed pulley, and start walking after releasing the fixed state of the trolley 1, so that the trolley 1 and the lower pipe guide frame 2 are moved horizontally as a whole to the position of the drainage pipe 15, and the trolley 1 is fixed again. At this time, the traction rope 4 used for on-site construction is passed around the pulley structure 3 and one end is fixed to the drainage pipe 15, and the other end is fixed to the traction equipment forklift on the bridge deck, and then the forklift is first moved horizontally to the bridge as shown in the figure. Figure 1 As shown, the right side is moved to pull up the drain pipe 15 so that it is suspended in the air, and then it is moved to the left to move the drain pipe 15 along the lower pipe track. After reaching the predetermined lowering position, the set traction rope 4 is used to prevent the drain pipe 15 from shaking during the lowering process. The traction rope 4 is released by the personnel on the bridge inspection vehicle, and then one end of the traction rope 4 is fixed to the forklift, and the other end is fixed to the drain pipe 15 through the drainage hole on the bridge deck. The forklift assists in completing the installation of the drain pipe 15.

[0029] The utility model is a device for installing a large-diameter along-the-bridge drainage pipe 15 on the deck of a steel-concrete composite beam bridge. The device is used for installing the large-diameter drainage pipe 15 and has a simple structure, is easy to install, and has strong applicability. The trolley 1 can drive the lower pipe guide frame 2 to move on the bridge deck, which occupies a small space on the bridge deck and is convenient to use during construction. The pulley structure and the lower pipe guide frame 2 limit the movement trajectory of the guide drainage pipe 15. The traction equipment forklift is used to cooperate with the lowering of the drainage pipe 15, which replaces the setting and use of the traditional crane or hanging basket. The working surface required during the installation of the bridge deck drainage pipe 15 is small, the investment in lifting equipment is reduced, and the construction cost is effectively saved.

[0030] In another technical solution, Figure 1-2As shown, the lower tube guide frame 2 includes an upper cross frame 5, a lower cross frame 7 and a vertical pole frame 6 connected between the upper cross frame 5 and the lower cross frame 7. The lower cross frame 7 extends toward the inner side of the bridge to the installation position of the drain pipe 15. A lowering space for the drain pipe 15 is formed between the vertical pole frame 6 and the outer side edge corresponding to the bridge deck. The pulley structure 3 is arranged on the upper cross frame 5 just above the lowering space. An inclined pole frame 8 is connected between the vertical pole frame 6 below the bridge deck and the lower cross frame 7 in a direction inclined toward the bottom of the bridge deck. The portion of the vertical pole frame 6 above the inclined pole frame 8, the inclined pole frame 8, and one end of the lower cross frame 7 toward the installation position of the drain pipe 15 together form a lower tube track for guiding the drain pipe 15 to move downward.

[0031] The end of the upper truss away from the trolley 1 extends outwardly toward the cross bridge and is connected to the vertical pole frame 6 at a 90° angle. The vertical pole frame 6 extends vertically downward, and the downwardly extending end is connected to the lower horizontal frame 7 at a 90° angle again. The lower horizontal frame 7 is as shown in FIG. Figure 1 The right end shown extends inwardly toward the cross bridge to the installation position of the drain pipe 15. The upper cross frame 5 and the lower cross frame 7 generally include a pair of parallel cross bars respectively, and the vertical bar frame 6 includes a pair of vertical vertical bars. One end of the upper cross bar is connected to the upper end of the trolley 1, and the other end of the cross bar is connected to the upper end of the vertical bar. The lower end of the vertical bar is connected to one end of the lower cross bar, and the other end of the lower cross bar extends toward the inside of the bridge. The upper section of the vertical bar, the inclined bar frame 8, and the right section of the lower cross bar form a three-section lower pipe track to guide the movement of the limited drain pipe 15 on the cross section of the bridge. The inclination angle of the inclined bar frame and the distance from the outer side of the bridge deck and the height of the lower cross frame are to ensure that the cross bridge has enough space for the drain pipe to the inside, and it is advisable not to interfere with the movement of the drain pipe.

[0032] In another technical solution, Figure 1 As shown, the upper cross frame 5 is downwardly connected with an auxiliary strut 9, which is located on the outside of the sidewalk guardrail 17. A roller 10 is installed at the bottom of the auxiliary strut 9, and the roller 10 rolls on the bridge deck along the direction of the bridge.

[0033] When going up along the bridge, auxiliary struts 9 are respectively arranged at the front and rear ends of the upper cross frame 5. The auxiliary struts 9 move synchronously with the trolley 1 through the rollers 10 arranged at the bottom. The rollers 10 are supported on the bridge deck, further improving the overall stability of the trolley 1 and the lower pipe guide frame 2. When the drainage pipe 15 is connected to the bridge deck through the traction rope 4, the drainage pipe 15 is first placed outside the auxiliary struts 9, that is, Figure 1 In the space between the upright pole frame 6 and the auxiliary support rod 9 shown.

[0034] In another technical solution, Figure 1 As shown, the corresponding connections between the trolley 1, the upper cross frame 5, the lower cross frame 7, and the upright frame 6 are connected by respectively setting connecting plates 11 and screwing in high-strength bolts.

[0035] The connecting plate 11 is a 1 cm thick steel plate, and high-strength bolts are used to connect the lower tube guide frame 2, the trolley 1, and the auxiliary support rod 9 to transmit the reaction force of the trolley 1 and the stress borne by the track. The corners of the lower tube guide frame 2 are all connected with the connecting plate 11 to facilitate the adjustment of the angle and size.

[0036] In another technical solution, Figure 1 As shown, a safety rope 12 is detachably connected between the trolley 1 and the corresponding position of the guardrail 16 of the upward lane of the cross bridge.

[0037] When the position of the trolley 1 needs to be fixed, move the cross bridge of the trolley 1 inwards. Figure 1 The right side shown is connected to the existing anti-collision guardrail and the lane guardrail 16 by a safety rope 12 to improve the stability and safety of the overall structural support when operating the drainage pipe 15. When the trolley 1 needs to move, the connection of the safety rope 12 is released.

[0038] In another technical solution, Figure 1 As shown, the end of the lower cross frame 7 facing the installation position of the drain pipe 15 is connected upward with a baffle 13. The baffle 13 is arranged as shown in FIG. Figure 1 The right side of the lower cross frame 7 shown in the figure acts as a barrier to prevent the drain pipe 15 from moving laterally too fast and detaching from the lower cross frame 7 .

[0039] In another technical solution, Figure 1-2 As shown, the trolley 1 is provided with a counterweight 14. A concrete counterweight 14 is placed at each end of the trolley 1 along the bridge, each weighing 400 kg, to improve the load-bearing stability of the trolley 1.

[0040] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the drawings shown and described herein.
