Description

Technical Field

[0001] The present invention relates to the technical field of drainage facilities, and in particular to an installation device for bridge deck drainage facilities and a use method thereof. Background Art

[0002] Most bridges are reinforced concrete structures. If water corrodes the steel bars, they will rust and shorten the service life of the bridge. Bridges corroded by water in winter are prone to ice, which can easily lead to concrete damage. If the drainage of the bridge deck is not handled properly, it will not only be detrimental to driving safety, but also cause inconvenience to pedestrians and damage the structure of the bridge deck. Therefore, in order to prevent the durability of the bridge from being damaged by the accumulation of rainwater, it is necessary not only to set a waterproof layer in the bridge deck pavement, but more importantly, to reasonably design a bridge deck drainage system on the bridge deck that can guide rainwater to quickly drain out of the bridge.

[0003] Existing bridge deck drainage methods include a method of directly draining water by connecting the water inlet to the drain pipe, and a method of draining water by connecting the water inlet to the drain pipe and the downspout along the bridge pier. Drainage facilities are not only arranged on the side walls of the bridge deck, but also often arranged on the lower side of the bridge deck and at the piers, and construction work needs to be carried out at the bottom of the bridge using a construction basket. The construction platform at the bottom of the bridge is generally erected on the bridge, and slides along the length of the bridge with the help of the track laid on the bridge deck, thereby driving the construction basket set under the bridge to move, thereby realizing rapid construction in the length direction of the bridge. Then, because the construction basket is set across the width of the entire bottom of the bridge, when it moves to the vertically arranged piers at the bottom of the bridge, it is difficult for the construction basket to cross the piers to continue construction, and it needs to be disassembled and reassembled, which is very troublesome.

[0004] In the prior art, the patent application number CN201821118781.4 discloses a municipal bridge engineering construction platform, which is connected by sliding between the U-shaped frame and the slide rail section and the bottom ends of the two U-shaped frames are respectively slid in the horizontal direction to set the docking of the adjustment frame. When sliding to an obstacle, the docking adjustment frame can be quickly opened to achieve the continued sliding of the construction platform, and can be quickly re-joined after crossing the obstacle, so that the construction personnel can continue to work. However, in the process of specific operation and use, the adjustment frames on both sides of the construction platform are docked with the slots through the plug blocks and limited by the fixing bolts. The fixing bolts need to be installed or removed before and after the docking of the adjustment frames on both sides, so that the docking work of the adjustment frames still requires the staff to disassemble and reassemble some links, and the construction efficiency is still not effectively improved; and the sliding work between the adjustment frames on both sides still requires the winch to pull it, which makes the construction platform cost high, thereby increasing the cost of bridge drainage construction.

[0011] Preferably, an elastic telescopic rod is fixed on the working longitudinal frame, and an abutment plate is fixed on one end of the elastic telescopic rod away from the working longitudinal frame.

[0017] The present invention also discloses a method for using an installation device for bridge deck drainage facilities, comprising the following steps:

[0018] S1: The working platform is fixed at the lower end of the connecting frame connected to the tractor, so that the working platform is placed on the lower side of the bridge, and the tractor is controlled to move so that the tractor drives the working platform through the connecting frame to the area of ​​the bridge where the drainage facilities are to be installed. The workers move along the working horizontal frame and the working vertical frame, and install the drainage facilities on the side of the bridge deck and the lower side of the bridge deck according to the installation requirements;

[0019] S2: The staff then continues to control the tractor to drive the working platform to move along the bridge, so that the working platform moves to the next location where the drainage facilities are to be installed;

[0020] S3: When the working platform moves with the tractor, the working longitudinal frame of the working platform abuts against the pier on the lower side of the bridge;

[0021] The abutment plate first abuts against the bridge pier, and the abutment plate is subjected to force to compress the elastic telescopic rod, and the elastic telescopic rod is deformed to buffer and unload the force on the abutment plate;

[0022] When the abutment plate moves, the plug-in block is driven to squeeze the plug-in slot of the plug-in rod, and the plug-in rod is forced to move upward so that its bottom is separated from the plug-in hole of the fixed plate, and the working frames on both sides of the working platform are no longer plugged into each other;

[0023] As the working platform moves along the bridge, the working longitudinal frame continues to abut against the bridge pier, and the working longitudinal frame deflects relative to the working transverse frame;

[0024] When the abutment plate moves, it drives the push rod to push the side of the swing rod, so that the swing rod rotates around the first pin shaft, and the swing rod drives the connecting rod and the protective rod to move, so that the swing rod cooperates with the connecting rod and the protective rod to block the open end of the working longitudinal frame, thereby protecting the construction personnel moving in the working longitudinal frame. The construction personnel can install drainage facilities along the working longitudinal frame at the pier position abutting against the working longitudinal frame at this time;

[0025] S4: When the abutment plate no longer abuts against the pier, the working longitudinal frame on the front side of the working platform passes over the pier, and the rotating rod drives the working longitudinal frame to reset and rotate under the action of the first torsion spring, so that the two working longitudinal frames are reconnected. At this time, the pier is placed between the working longitudinal frames at both ends of the working cross frame. The construction workers drive the working platform to stop or continue to move by the tractor according to the installation position of the drainage facilities until the installation of the drainage facilities of the entire bridge is completed.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The installation device and the use method of the bridge deck drainage facility enable the tractor to use the connecting frame to drive the working platform to move under the bridge, so that the construction personnel can move on the working platform along the U-shaped groove of the working horizontal frame and the working vertical frame, and can construct and install drainage facilities at any position of the bridge side and bottom piers to ensure smooth drainage of the bridge. The entire working platform is symmetrically placed under the bridge, so that the working vertical frames connected on both sides can automatically separate when sliding to the pier obstacle, so as to achieve the continuous sliding of the working platform, avoid hindering the movement of the working platform, and can be quickly reassembled after crossing the pier obstacle, without the need for additional disassembly and reorganization by the staff, effectively improving the construction efficiency, and using the bearing force with the pier to automatically separate and adjust the working vertical frame, without the need to use other power equipment to adjust the position of the working vertical frame, effectively reducing the cost of bridge deck drainage construction;

[0028] 2. The installation device for bridge deck drainage facilities and the use method thereof, when the abutment plate moves, the push rod is driven to push the side of the swing rod, so that the swing rod rotates around the first pin shaft, and the swing rod drives the connecting rod and the protective rod to move, so that the swing rod cooperates with the connecting rod and the protective rod to block the open end of the working longitudinal frame, thereby protecting the construction personnel moving in the working longitudinal frame, preventing the construction personnel from falling from the opening at the end of the working longitudinal frame, and ensuring the safety of the installation operation of the bridge deck drainage facilities;

[0049] Specifically, the working platform 3 is fixed to the lower end of the connecting frame 2 connected to the tractor 11 (it should be noted that the connecting frame 2 should be provided with a lifting device for driving the working platform 3 to rise and fall, so that the working platform 3 can install drainage facilities at different heights. Controlling the lifting of the working platform 3 is a prior art and will not be described in detail here). The working platform 3 is placed on the lower side of the bridge 1, and the tractor 11 is controlled to run so that the tractor 11 drives the working platform 3 to move to the area of ​​the bridge 1 where the drainage facilities are to be installed through the connecting frame 2. The limiting guide part 4 provided on the connecting frame 2 abuts against the side of the bridge 1 through the limiting wheel 402, so as to limit the moving direction of the working platform 3 and the tractor 11. The staff moves along the working horizontal frame 302 and the working vertical frame 303 according to the installation needs. , drainage facilities are installed on the side of the bridge deck and at the position to be installed on the lower side of the bridge deck, and the two groups of working frames 301 of the working platform 3 are plugged into each other, so that the two groups of plugged working frames 301 are automatically separated when they abut against the pier 101 on the lower side of the bridge 1, avoiding obstruction to the movement of the working platform 3, and when the working longitudinal frame 303 rotates relative to the working cross frame 302, the filling frame 304 can fill the gap between the working longitudinal frame 303 and the working cross frame 302, avoiding the staff from falling when moving to the junction of the working longitudinal frame 303 and the working cross frame 302, thereby ensuring the safe installation of the drainage facilities of the bridge 1; and the entire working platform 3 is symmetrically placed on the lower side of the bridge 1, effectively avoiding the unstable center of gravity caused by placing the existing working platform 3 on one side of the bridge 1.

[0050] Example 2: Reference Figure 1-Figure 11 , a mounting device for bridge deck drainage facilities, based on Example 1, further, two groups of working frames 301 of the working platform 3 are provided with plug-in components, the plug-in components include a support plate 5 fixedly mounted on the working longitudinal frame 303, a plug-in rod 501 is slidably connected to the support plate 5, a limit plate 502 is fixedly arranged on the top of the plug-in rod 501, an elastic element 503 whose two ends are respectively connected to the limit plate 502 and the support plate 5 is sleeved on the outer side of the plug-in rod 501, the plug-in component also includes a fixed plate 6 fixedly mounted on the other working longitudinal frame 303, a plug-in hole 601 is provided on the fixed plate 6 for matching with the plug-in rod 501 on the other working longitudinal frame 303, and an extrusion slope is provided on the end of the plug-in rod 501 away from the limit plate 502.

[0051] Furthermore, an elastic telescopic rod 7 is fixedly provided on the working longitudinal frame 303, and an abutment plate 701 is fixedly provided at one end of the elastic telescopic rod 7 away from the working longitudinal frame 303. The abutment plate 701 and the bridge pier 101 are movably abutted against each other, and a plug-in block 702 is fixedly provided on the outer side of the abutment plate 701. The plug-in block 702 is slidably connected to the plug-in rod 501 and is used to drive the plug-in rod 501 to perform lifting and lowering movements.

[0052] Furthermore, a plug-in slot 5011 for sliding the plug-in block 702 is formed on the plug-in rod 501 , and an upper inner wall of the plug-in slot 5011 and an upper side of the end of the plug-in block 702 are both formed with inclined surfaces that are movable against each other.

[0053] Specifically, initially, the plug-in rods 501 of two adjacent working vertical frames 303 are plugged into the fixing plate 6 to achieve connection and locking of the two working vertical frames 303;

[0054] When the working platform 3 moves with the tractor 11, the working longitudinal frame 303 of the working platform 3 abuts against the pier 101 at the lower side of the bridge 1, and the abutting plate 701 abuts against the pier 101 first. The abutting plate 701 is subjected to force to compress the elastic telescopic rod 7, and the elastic telescopic rod 7 is deformed to buffer and unload the force on the abutting plate 701.

[0055] When the abutment plate 701 moves, the plug-in block 702 is driven to squeeze the plug-in slot 5011 of the plug-in rod 501, and the plug-in rod 501 is forced to move upward so that its bottom is separated from the plug-in hole 601 of the fixed plate 6, and the work frames 301 on both sides of the work platform 3 are no longer plugged into each other, so that the two groups of plugged work frames 301 are automatically separated when they abut against the pier 101 on the lower side of the bridge 1, avoiding obstruction to the movement of the work platform 3, thereby ensuring the normal installation of the drainage facilities of the bridge 1;

[0056] As the working platform 3 moves along the bridge 1, the working longitudinal frame 303 continues to abut against the bridge pier 101, and the working longitudinal frame 303 deflects relative to the working transverse frame 302, so that the construction workers can install drainage facilities along the working longitudinal frame 303 at the position of the bridge pier 101 abutting against the working longitudinal frame 303 at this time;

[0057] When the abutment plate 701 is no longer in abutment with the bridge pier 101, the working longitudinal frame 303 on the front side of the working platform 3 passes over the bridge pier 101, and the rotating rod 8 drives the working longitudinal frame 303 to reset and rotate under the action of the torsion spring, so that the two working longitudinal frames 303 are reconnected.

[0059] Specifically, by setting an auxiliary roller 7012 on the outside of the main body 7011, the abutting plate 701 contacts the pier 101 through the auxiliary roller 7012 during the abutment between the abutting plate 701 and the pier 101, so that the sliding friction is converted into rolling friction, thereby reducing the degree of wear when the abutting plate 701 and the pier 101 abut.

[0060] Example 4: Reference Figure 5 , Figure 6 and Fig.11 , a mounting device for bridge deck drainage facilities, based on Example 3, further, the bottom of the working longitudinal frame 303 is rotatably connected to two swing rods 9 through a first pin shaft, the first pin shaft is sleeved with a second torsion spring for driving the swing rod 9 to reset and rotate, the middle parts of the two swing rods 9 are rotatably connected to a connecting rod 901 through a second pin shaft, the end of the swing rod 9 away from the first pin shaft is movably connected to a protective rod 902, and a push rod 10 that movably abuts against the swing rod 9 is provided on the abutment plate 701.

[0061] Specifically, when the abutment plate 701 moves, it also drives the push rod 10 to push the side of the swing rod 9, so that the swing rod 9 rotates around the first pin axis, and the swing rod 9 drives the connecting rod 901 and the protective rod 902 to move, so that the swing rod 9 cooperates with the connecting rod 901 and the protective rod 902 to seal the open end of the working longitudinal frame 303, thereby protecting the construction personnel active in the working longitudinal frame 303 and preventing the construction personnel from falling from the opening at the end of the working longitudinal frame 303, thereby ensuring the safety of the installation of the bridge deck drainage facilities.
