Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a novel ultra-wide front support point guy rope hanging basket thrust stop device. Background Art

[0002] The front support cable hanging basket construction is widely used in the construction technology of cable-stayed bridges. For bridge decks with smaller widths, a double C hanging ear type walking structure can be used. However, due to the requirements of the throughput rate of modern traffic, the width of the bridge deck is required to be wider and wider. At this time, the double C hanging ear type walking structure may not be able to support the hanging basket, so it is necessary to lay a special walking track on the already cast beam section.

[0003] During the construction of the front support cable-stayed basket for extra-wide bridge decks, it is generally necessary to lay more than four special walking tracks on the already cast beam section. When the basket is moving, a stronger hanging leg mechanism and walking counter-pressure mechanism are required to balance the forward tilting force of the basket, which also places high requirements on the thrust force of the thrust device.

[0004] Based on this, for a hanging basket traveling structure with multiple parallel tracks, the present invention attempts to propose a new type of thrust stop device to improve the stability and safety of the thrust stop action. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a novel super-wide front fulcrum rope hanging basket thrust device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A novel ultra-wide front fulcrum cable hanging basket thrust device comprises support blocks arranged at the guardrails on both sides of the cast bridge deck, a fixed support arranged at one side of the end of the hanging basket walking track, and a movable support arranged at one side of the walking mechanism. The support block is specifically a rectangular parallelepiped, and two groups of through-cross bars and a horizontal square steel column are interspersed on the two side surfaces of the support block in a direction perpendicular to the bridge body cross beam. A first fixed steel bar is also interspersed on the top surface of the support block. The first fixed steel bar is vertically arranged and passes through the horizontal square steel column and is inserted into the reserved hole on the cast bridge deck. Any group of through-cross bars is erected by two groups of symmetrical support blocks, and end nuts are provided at both ends of the through-cross bars. The first support legs are symmetrically provided at the bottom of the two side surfaces of the support block in a direction parallel to the bridge body cross beam. The first support leg is welded by a bottom plate and two right-angle plates arranged at both ends of the upper surface of the bottom plate. The first support leg and the support block are integrally formed, and the bottom plate of the first support leg is inserted into another reserved hole on the cast bridge deck through a second fixed steel bar.

[0008] The fixed support mainly includes an anti-slip plate, an L-shaped support plate and a locking frame. The anti-slip plate is placed flat on one side at the end of the hanging basket walking track, and the side wall of the anti-slip plate is in contact with the outer side wall of the hanging basket walking track. The bottom plate and the middle part of the side plate of the L-shaped support plate are welded by another right-angled plate. The bottom plate of the L-shaped support plate and the anti-slip plate are inserted into the third group of reserved holes on the cast bridge deck through the third fixing steel bars. The side plate of the L-shaped support plate and the anti-slip plate form a right-angled chute, and the back and bottom of the locking frame are in contact with the right-angled chute;

[0009] The locking frame is specifically an inverted "卩"-shaped frame body composed of a top plate, a bottom plate and a special-shaped block between the top plate and the bottom plate. The length of the top plate of the locking frame is less than the length of the bottom plate. Smooth through holes sleeved with through cross bars are provided at the top and bottom of both sides of the special-shaped block. A rectangular groove is provided on the upper surface of the bottom plate of the locking frame. The two side walls of the rectangular groove are provided with female head locks through two pin shafts. The female head lock is composed of an upper U-shaped plate and a hinge chain arranged in the middle of the bottom surface of the U-shaped plate. The two ends of the hinge chain are respectively riveted to the inner side wall of the rectangular groove through pin shafts. One side of the bottom surface of the U-shaped plate of the female head lock close to the special-shaped block of the female head lock is fixed to the special-shaped block of the female head lock through a spring. The initial state of the U-shaped plate of the female head lock is that the opening is obliquely upward, and there is a gap between the upturned end of the U-shaped plate and the top plate of the locking frame in the initial state;

[0010] The movable support is also specifically an inverted "卩"-shaped frame body composed of a top plate, a bottom plate and a special-shaped block between the top plate and the bottom plate. The movable support and the locking frame are of the same structure arranged symmetrically. The length of the top plate of the movable support is greater than the length of the bottom plate. Fixed bolts are inserted through the top and bottom of both sides of the special-shaped block of the movable support. The movable support is fixedly connected to one side of the walking mechanism through two groups of fixed bolts, and sealing nuts are also provided at both ends of the fixed bolts;

[0011] A rectangular groove is also opened on the bottom surface of the top plate of the movable support. A male head lock is arranged on the rectangular groove of the movable support through a pin shaft. The male head lock is composed of a lower U-shaped plate and a hinge chain arranged in the middle of the top surface of the U-shaped plate. One side of the U-shaped plate of the male head lock close to the special-shaped block of the male head lock is fixed to the special-shaped block of the male head lock through a spring. The initial state of the U-shaped plate of the male head lock is that the opening is obliquely downward, and there is a gap between the drooping end of the U-shaped plate and the bottom plate of the movable support in the initial state;

[0012] The height of the top plate of the movable support is located at the gap position between the top plate of the locking frame and the U-shaped plate of the female head lock. The height of the bottom plate of the locking frame is located at the gap position between the bottom plate of the movable support and the U-shaped plate of the male head lock. The U-shaped plate of the female head lock and the U-shaped plate of the male head lock are clamped together to form a rectangular frame structure, and the horizontal square steel column is movably sleeved in the rectangular frame structure.

[0013] Preferably, the upper parts of the first fixed steel bar, the second fixed steel bar and the third fixed steel bar are respectively capped by straight threaded steel bar joints, and the straight threaded steel bar joints are used to facilitate the installation and disassembly of the support block and the fixed support.

[0014] One use environment of the present invention is that the support block, the hanging basket walking track, the fixed support, the walking mechanism and the movable support are all arranged on the upper surface of the cast bridge deck. The thrust device of the present invention can be installed on the upper surface of the bridge and is suitable for the walking mechanism of the upper sliding track. The thrust device of this walking mode needs to have a reserved hole on the bridge deck, and can also directly set the first fixed steel bar, the second fixed steel bar and the third fixed steel bar embedded in the guardrail. The first fixed steel bar and the second fixed steel bar embedded in the guardrail can be used as guardrail reinforcement parts later, and the third fixed steel bar in the middle of the road surface needs to be cut and roughened.

[0015] Another use environment of the present invention is that the support block, the hanging basket walking track, the fixed support, the walking mechanism and the movable support are all arranged on the lower surface of the cast bridge deck. The thrust device of the present invention can be installed on the lower surface of the bridge, and is suitable for the walking mechanism of the lower sliding track. The thrust device of this walking mode has few restrictions, and the reserved hole can be filled by additional pouring; if the embedded steel bar method is adopted, the embedded steel bar can be roughened and additionally poured, and can also be used for steel bar binding of expansion joints; but when it is arranged on the lower surface of the bridge, it is necessary to fix the lock frame on the L-shaped support plate and the anti-slip plate by bolting and welding to form a non-detachable fixed support.

[0016] According to the aforementioned structure, the present invention further proposes a method for using a novel ultra-wide front fulcrum guy rope hanging basket thrust stop device, comprising the following steps:

[0017] a. According to the specific walking mode of the cable hanging basket, a novel ultra-wide front fulcrum cable hanging basket thrust device of the present invention is arranged on the upper surface or lower surface of the bridge, and the hanging basket walking track is pre-laid and the walking mechanism is pulled and fixed, the support block is fixed to the guardrails on both sides of the cast bridge deck through the second fixed steel bar, the fixed support is installed on one side of the end of the hanging basket walking track through the third fixed steel bar, the mobile support is arranged on one side of the walking mechanism through the fixing bolt, and the mobile support and the lock frame are located on the straight line of the same track and the openings are arranged oppositely, and the openings of the male lock U-shaped plate and the female lock U-shaped plate are also arranged oppositely;

[0018] b. Multiple sets of fixed supports are mounted on two sets of symmetrical support blocks through two sets of through-cross bars, and the through-cross bars are sealed;

[0019] c. The walking mechanism is controlled to slide on the walking track of the hanging basket through the traction device. When the top plate of the mobile support touches the U-shaped plate of the female lock buckle, the U-shaped plate of the female lock buckle and the U-shaped plate of the male lock buckle are clamped together under the impact force to form a rectangular frame structure. At this time, another traction and towing device is used to insert the horizontal square steel column into the support block and multiple groups of rectangular frame structures in sequence, and then the horizontal square steel column is pinned by the first fixed steel bar, so that the support block, the fixed support and the mobile support are locked and fixed together to complete the thrust work;

[0020] d. When the operation on the guy wire hanging basket is completed and a new casting surface is formed, continue to lay new support blocks, hanging basket walking tracks and fixed supports, and make the new hanging basket walking tracks dock with the previous hanging basket walking tracks, retain the previous support blocks as a suspension or support structure, remove the previous horizontal square steel column, control the walking mechanism to slide in the opposite direction through the traction device, pull the U-shaped plate of the male lock buckle to the right, causing the U-shaped plates of the male lock buckle and the female lock buckle to tilt up respectively, continue to slide for a distance, then the male lock buckle will be smoothly separated from the female lock buckle, and then fix the walking mechanism, and then remove the previous through cross bar and fixed supports to complete a section of unloading work;

[0021] e. Push the walking mechanism to slide forward and enter the newly laid hanging basket walking track, and repeat the operations of steps ad to complete the entire walking-thrusting and unloading work.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention adopts a female lock buckle and a male lock buckle of a simple U-shaped frame structure, wherein the female lock buckle is arranged on a fixed support, and the male lock buckle is arranged on a movable support. The male lock buckle of the movable support is driven by a walking mechanism to impact the female lock buckle, and the two are locked to form a rectangular frame structure, and then a horizontal square steel column is connected in the rectangular frame to form a new clutch locking structure, which can realize clutch locking and unlocking only by the forward and reverse sliding of the walking mechanism, and is convenient to use;

[0024] 2. In addition to its own fixing function, the fixed support of the present invention is also fixed to the support blocks at both ends by penetrating the crossbar and the horizontal square steel column. It has a strong thrust force and converts part of the impact force into a bending moment penetrating the crossbar and the horizontal square steel column. The thrust force has a buffering effect, which improves the stability of the walking thrust.

[0025] 3. The method for using a novel ultra-wide front fulcrum cable hanging basket thrust device proposed in the present invention completes the entire walking-thrusting-unloading work only through the forward and reverse sliding of the walking mechanism, and the installation, fixing and disassembly process is simple and clear, which greatly reduces the laying process of the cable hanging basket embedded parts and speeds up the hanging basket casting construction of the cable-stayed bridge.

The initial state of the U-shaped plate of the male lock (602) is that the opening is obliquely downward, and there is a gap between the hanging end of the U-shaped plate and the bottom plate of the movable support (6) in the initial state. The height of the top plate of the movable support (6) is located at the gap between the top plate of the lock frame (403) and the U-shaped plate of the female lock (407). The height of the bottom plate of the lock frame (403) is located at the gap between the bottom plate of the movable support (6) and the U-shaped plate of the male lock (602). The U-shaped plate of the female lock (407) and the U-shaped plate of the male lock (602) are clamped together to form a rectangular frame structure. The horizontal square steel column (202) is movably sleeved in the rectangular frame structure. The upper parts of the first fixing steel bar (203), the second fixing steel bar (205) and the third fixing steel bar (404) are respectively sealed by straight thread steel bar joints. The support block (2), the hanging basket traveling track (3), the fixed support (4), the traveling mechanism (5) and the movable support (6) are all arranged on the upper surface or the lower surface of the cast-in-place bridge deck (1).

2. The method for using the novel super-wide front fulcrum guy rope hanging basket thrust device according to claim 1 is characterized in that: Including the following steps: a. According to the traveling mode of the specific cable-stayed hanging basket, a novel ultra-wide front fulcrum cable-stayed hanging basket thrust device of the present invention is arranged on the upper surface or the lower surface of the bridge, and the hanging basket traveling track (3) is pre-laid and the traveling mechanism (5) is牵引固定好 (traction-fixed). The support block (2) is fixed at both sides of the guardrail of the cast-in-place bridge deck (1) through the second fixing steel bar (205). The fixed support (4) is installed at one side position at the end of the hanging basket traveling track (3) through the third fixing steel bar (404). The movable support (6) is arranged at one side position of the traveling mechanism (5) through the fixing bolt (601), and the movable support (6) and the lock frame (403) are located on the same straight line of the track and are arranged with openings opposite to each other. The openings of the U-shaped plates of the male lock (602) and the female lock (407) are also arranged opposite to each other. b. The plurality of fixed supports (4) are mounted on two sets of symmetrical support blocks (2) through two sets of through-cross bars (201), and the through-cross bars (201) are sealed; c. The walking mechanism (5) is controlled to slide on the walking track (3) of the hanging basket by means of a traction device. When the top plate of the movable support (6) touches the U-shaped plate of the female lock buckle (407), the U-shaped plate of the female lock buckle (407) and the U-shaped plate of the male lock buckle (602) are clamped together under the action of the impact force to form a rectangular frame structure. At this time, another traction and towing device is used to sequentially insert the horizontal square steel column (202) into the support block (2) and the plurality of rectangular frame structures. The horizontal square steel column (202) is then pinned by means of the first fixed steel bar (203), thereby locking and fixing the support block (2), the fixed support (4) and the movable support (6) together to complete the thrust stop work. d. When the operation on the guy wire hanging basket is completed and a new casting surface is formed, continue to lay new support blocks (2), hanging basket walking tracks (3) and fixed supports (4), and make the new hanging basket walking tracks (3) dock with the previous hanging basket walking tracks (3), retain the previous support blocks (2) as a suspension or support structure, remove the previous horizontal square steel column (202), control the walking mechanism (5) to slide in the opposite direction through the traction device, pull the U-shaped plate of the male lock buckle (602) to the right, causing the U-shaped plates of the male lock buckle (602) and the female lock buckle (407) to tilt up respectively, continue to slide for a distance, then the male lock buckle (602) is successfully separated from the female lock buckle (407), and then fix the walking mechanism (5), and then remove the previous through cross bar (201) and fixed supports (4) to complete a section of unloading work; e. Push the walking mechanism (5) to slide forward and enter the newly laid hanging basket walking track (3), and repeat the operation of steps ad to complete the entire walking-thrusting and unloading work.
