Description

Technical Field

[0001] This invention relates to the field of mounting hole fixing brackets, specifically a mounting hole fixing bracket for a steel cage. Background Technology

[0002] In bridge pile foundation construction, temporary fixing of the rebar cage is always completed inside the borehole during the extension and lowering process. In traditional pile foundations, the rebar cage is relatively lightweight, and a sling is used to hold the cage horizontally on temporary square timber placed around the borehole. With the increasing popularity of large bridge construction, ultra-long pile foundations are widely used, and the weight of the pile foundation rebar cage has increased accordingly. The traditional method of temporarily fixing the rebar cage with a sling requires high rigidity of the sling, and the weight of the sling may even exceed the range of manual operation, leading to a decrease in efficiency. When the rebar cage is extended and lowered, a temporary fixing frame is needed on one side of the installation hole to complete the lowering of the rebar cage. As shown in the comparison document 1 The prior art, represented by a tool-type fixing frame for extending and protecting the reinforcing cage of cast-in-place piles (publication number CN102828505B), uses a sub-protective frame that passes through a connector on a main protective frame for fixation. The lower crossbar of the main protective frame is equipped with a locking clip to fix an adjustable hanging component. An I-beam passes through this adjustable hanging component and extends the reinforcing cage to another adjustable hanging component at the other end. This fixing frame of the present invention provides safety protection during the drilling and extension of the reinforcing cage of cast-in-place piles, preventing accidents and demonstrating good practicality. It effectively solves the problems of existing technologies. However, its structure still needs improvement, specifically as follows:

[0003] In this solution, the rebar cage installation orifice fixing frame suffers from several drawbacks. Since the rebar cages vary in size and design according to the column's tonnage, the device lacks the flexibility to adjust to accommodate different installation orifice sizes. Furthermore, the fixing frame lacks a leveling function. When installing the fixing frame at the orifice, the surrounding soil base needs to be leveled. However, manual leveling can be inefficient, leading to inaccuracies in the soil base and causing the fixing frame to tilt, affecting project quality. Installation is also inconvenient, requiring the fixing frame to be set up before lowering the rebar cage. During lowering, the fixing frame cannot be adjusted or replaced. After the rebar cage is lengthened, the fixing frame needs to be disassembled, but existing fixing frames are difficult to disassemble. Therefore, a fixing frame that is easy to adjust in size, can level, and has a simpler support structure for installation and release is needed. A more practical and practical rebar cage installation orifice fixing frame is required to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing rebar cage installation orifice fixing frames, such as the lack of flexibility to adapt to different sized orifices, the absence of leveling capabilities leading to cage tilting and affecting project quality, the inability to adjust or replace the frame during cage lowering, and the difficulty in disassembling the frame after cage lengthening, this invention provides a rebar cage installation orifice fixing frame to solve these problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fixing bracket for installing a steel cage includes a mounting plate, a fixing block is mounted on the base surface of the mounting plate, and a fixing component is plugged into and pulled onto the outer wall of the fixing block;

[0007] The fixing assembly includes a fixing housing. A slot is formed on the outer wall of the fixing housing, which is pluggable to the outer wall of a fixing block. A wire wheel motor is mounted on the outer wall of the fixing housing. A gearbox is mounted on the outer wall of the drive shaft of the wire wheel motor. A control panel is mounted on the outer wall of the gearbox. A wire wheel is mounted on the transmission end of the gearbox. A level detection sensor is embedded in the outer wall of the fixing housing. A support column is mounted on one side of the level detection sensor and on the outer wall of the fixing housing. A mounting groove is formed on the outer wall of the support column. The inner wall opposite the mounting groove has... A rotating shaft is rotatably connected to the rotating shaft. A fixing block is installed on the outer wall of the rotating shaft. A fixing groove is formed on the outer wall of the fixing block. A fixing rod is installed on the inner wall of the fixing groove, which is opposite to the fixing groove. A pulling steel rope is installed on the outer wall of the fixing rod. A fixing block is installed on one side of the rotating shaft and on the outer wall of the support column. A positioning groove is formed on the outer wall of the fixing block. A rotating shaft is rotatably connected to the inner wall of the positioning groove, which is opposite to the positioning groove. A sliding wheel is installed on the outer wall of the rotating shaft. The pulling steel rope is slidably connected to the outer wall of the sliding wheel. One end of the pulling steel rope extends to one side of the sliding wheel and is connected to a reel.

[0008] In a preferred embodiment of the present invention, the control panel is electrically connected to the wire wheel motor and the horizontal detection sensor via wires, and the fixing groove is a T-shaped structure.

[0009] As a preferred embodiment of the present invention, the mounting plate is provided in two sets, one long and one short, the mounting plate has an arc-shaped structure, and the fixing blocks are provided in multiple sets and are respectively located on the outer wall of the mounting plate.

[0010] As a preferred embodiment of the present invention, the spacing between the fixing blocks is distributed in an equidistant array, the fixing components are provided in multiple sets and are respectively located on the base surface of the mounting plate, and the edge of the fixing housing is a chamfered structure.

[0011] As a preferred embodiment of the present invention, the cross-section of the fixed housing is an L-shaped structure, two sets of slots are provided and are respectively located on the outer wall of the fixed housing, and the angle of the support column is inclined at 45° relative to the horizontal plane.

[0012] As a preferred embodiment of the present invention, the connection between the rotating shaft and the fixing block is a rotatable connection, the cross-section of the fixing block is a groove structure, and the fixing groove is located on one side of the rotating shaft.

[0013] As a preferred embodiment of the present invention, the fixing block and the support column are perpendicular to each other, the rotating shaft and the sliding wheel are connected by a rotatable connection, and the pulling steel rope is made of carbon steel wire.

[0014] Compared with the prior art, the present invention sets different sizes and lengths of mounting plates in the fixing frame for the installation holes of the reinforcing cage. The appropriate length of the mounting plate can be selected according to the site environment. Since there are multiple sets of fixing components, the appropriate number of fixing components can be selected according to the site construction conditions. The slots are inserted into the fixing blocks on the base surface of different mounting plates in sequence, so that the fixing shell can connect the mounting plates together. Small-sized installation holes can be fixed with three fixing components, and large-sized installation holes can be fixed with more than three fixing components. It can be flexibly adjusted to adapt to different installation holes.

[0015] Based on real-time device height information, the horizontal detection sensor generates an electrical signal that is transmitted to the control panel via wires. Workers can then adjust the device in a timely manner based on the height information on the control panel, either by raising or flattening the soil base at the bottom of the device, ensuring that the installation plate remains on the same horizontal plane. This prevents the steel cage from tilting due to the tilt of the fixing frame, which would affect the construction quality.

[0016] Pulling one end of the steel rope applies tension to the fixing rod, which simultaneously causes the fixing rod to rotate on the outer wall of the shaft. This makes the groove structure of the fixing block vertically upward, facilitating the clamping of the rebar cage onto the inner wall of the fixing block, thus completing the fixing function. The control panel controls the reel motor to rotate in the opposite direction, causing the pulling steel rope to lose its tension on the fixing rod and the fixing block to lose its supporting force on the rebar cage. The arc-shaped mounting plate facilitates installation and future replacement and maintenance. The equal distance between the fixing blocks facilitates the installation and fixing of components. The device is easy to disassemble and has better practicality. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Example: Please refer to Figure 1-8 The shown is a steel cage installation hole fixing bracket, including a mounting plate 1, a fixing block 2 installed on the base surface of the mounting plate 1, and a fixing component 3 plugged into and pulled onto the outer wall of the fixing block 2;

[0028] In this embodiment, specific references Figure 1 , Figure 5 and Figure 7The fixing component 3 includes a fixing housing 301. A slot 302 is formed on the outer wall of the fixing housing 301, which is pluggable to the outer wall of the fixing block 2. A spool motor 303 is mounted on the outer wall of the fixing housing 301. A gearbox 304 is mounted on the outer wall of the drive shaft of the spool motor 303. A control panel 305 is mounted on the outer wall of the gearbox 304. A spool disc 306 is mounted on the transmission end of the gearbox 304. A horizontal detection sensor 307 is embedded in the outer wall of the fixing housing 301. A support column 308 is mounted on one side of the horizontal detection sensor 307 and on the outer wall of the fixing housing 301. A mounting groove 309 is formed on the outer wall of the support column 308, and a rotatable connection is formed on the inner wall of the mounting groove 309. There is a rotating shaft 310, and a fixing block 311 is installed on the outer wall of the rotating shaft 310. A fixing groove 312 is opened on the outer wall of the fixing block 311. A fixing rod 313 is installed on the inner wall opposite to the fixing groove 312. A pulling steel rope 314 is installed on the outer wall of the fixing rod 313. A fixing block 315 is installed on one side of the rotating shaft 310 and on the outer wall of the support column 308. A positioning groove 316 is opened on the outer wall of the fixing block 315. A rotating shaft 317 is rotatably connected to the inner wall opposite to the positioning groove 316. A sliding wheel 318 is installed on the outer wall of the rotating shaft 317. The pulling steel rope 314 is slidably connected to the outer wall of the sliding wheel 318. One end of the pulling steel rope 314 extends to one side of the sliding wheel 318 and is connected to a wire reel 306.

[0029] The control panel 305 is electrically connected to the reel motor 303 and the horizontal detection sensor 307 via wires, enabling the device to be powered on. The mounting plate 1 has two sets, one long and one short, with an arc-shaped structure to facilitate selection of the appropriate length based on the size of the mounting holes. Multiple sets of fixing blocks 2 are located on the outer wall of the mounting plate 1, with equidistant array spacing between them. Two sets of slots 302 are located on the outer wall of the fixing housing 301. Because there are two sets of slots 302, they can be inserted sequentially into the fixing blocks 2 on different mounting plate 1 base surfaces, allowing the fixing housing 301 to connect the mounting plates 1 together, resulting in greater overall stability of the device. Multiple sets of fixing components 3 are located on the base surfaces of the mounting plates 1, offering better versatility. When the device is damaged, only one set of fixing components 3 needs to be replaced, resulting in lower economic costs and better practicality.

[0030] The fixing groove 312 has a T-shaped structure, which allows the pulling steel rope 314 to be hidden inside the fixing groove 312 when it is extended, thus preventing the pulling steel rope 314 from affecting the lowering of the reinforcing cage.

[0031] The fixed housing 301 has a chamfered edge to prevent injury to on-site construction personnel, improving safety. The support column 308 is inclined at 45° relative to the horizontal plane, allowing it to better apply force to the outer wall of the fixed housing 301. The fixed housing 301 has an L-shaped cross-section. When the support column 308 is subjected to downward pressure, the protruding part of the fixed housing 301 increases the contact area between the fixed housing 301 and the soil foundation, resulting in more even stress distribution on the soil and preventing sagging. The connection between the rotating shaft 310 and the fixing block 311... The method of rotational connection makes the rotation of the device easier. The cross-section of the fixing block 311 is a groove structure. The fixing groove 312 is located on one side of the rotating shaft 310. The fixing block 315 and the support column 308 are perpendicular to each other. The top of the fixing block 315 is higher than the top of the support column 308, so that when the steel rope 314 pulls the fixing rod 313, one end of the fixing block 311 is more easily subjected to tension. The rotating shaft 317 and the sliding wheel 318 are connected by rotation. The steel rope 314 is made of carbon steel wire, which makes the structure of the steel rope 314 stronger.

[0032] In this design, the fixing bracket for the rebar cage installation openings uses fixing blocks 2 installed on the base surface of the mounting plate 1. Fixing components 3 are plugged into and pulled onto the outer wall of the fixing blocks 2. The mounting plate 1 has two sets, one long and one short. Due to its arc-shaped structure, the size of the mounting plate 1 can be adjusted according to the size and shape of the rebar cage. A suitable length of mounting plate 1 can be selected based on the site conditions. Since multiple sets of fixing components 3 are provided, an appropriate number of fixing components 3 can be selected according to the site construction situation. With the fixing blocks 2 spaced in an equidistant array, two sets of slots 302 are provided, each located on the outer wall of the fixing housing 301. Because there are two sets of slots 302, the blocks can be inserted sequentially into different locations. On the same mounting plate 1 base surface, the fixing blocks 2 allow the fixing housing 301 to connect the mounting plate 1 together. Small-sized mounting holes can be fixed with three fixing components 3, while large-sized mounting holes can be fixed with more than three fixing components 3. The overall stability of the device is stronger, the installation method is more flexible, and the fixing components 3 have better versatility. When the device is damaged, only one set of fixing components 3 needs to be replaced, resulting in lower economic costs and better practicality. This solves the problem that when using the rebar cage mounting hole fixing bracket, since the rebar cage is designed with different sizes according to the column tonnage, the device does not have the function of flexibly adjusting to adapt to different sizes of mounting holes.

[0033] A control panel 305 is mounted on the outer wall of the gearbox 304. A pulley 306 is mounted on the transmission end of the gearbox 304. A horizontal detection sensor 307 is embedded in the outer wall of the fixed housing 301. During installation, the horizontal detection sensor 307 generates an electrical signal based on real-time device height information, which is transmitted to the control panel 305 via wires. The control panel 305 analyzes and processes the data and then displays the height information in real-time on its screen. This allows workers to adjust the device promptly based on the height information, such as raising or flattening the soil base at the bottom of the device, ensuring the mounting plate 1 remains on the same horizontal plane and preventing tilting of the mounting frame. The tilting of the reinforcing cage affects construction quality. Simultaneously, the 45° tilt of the support column 308 relative to the horizontal plane allows it to better apply force to the outer wall of the fixed shell 301. The fixed shell 301 has an L-shaped cross-section. When the support column 308 is subjected to downward pressure, the protruding part of the fixed shell 301 increases the contact area between the fixed shell 301 and the soil foundation, resulting in more even soil stress and preventing sagging. This solves the problem that the fixing frame at the installation hole of the reinforcing cage does not have a leveling function. When installing the fixing frame at the installation hole, the surrounding soil base needs to be leveled. However, if manual leveling is done without sufficient experience, the soil base may not be completely parallel to the horizontal plane, leading to errors in the fixing frame and causing the reinforcing cage to tilt, thus affecting project quality.

[0034] A spool motor 303 is mounted on the outer wall of the fixed housing 301. A gearbox 304 is mounted on the outer wall of the drive shaft of the spool motor 303. When the switch on the control panel 305 is turned on, the control panel 305 controls the operation of the spool motor 303, causing the drive shaft of the spool motor 303 to output power. The drive shaft of the spool motor 303 drives the gearbox 304 to transmit power. Simultaneously, a fixing block 315 is mounted on one side of the rotating shaft 310 and on the outer wall of the support column 308. A positioning groove 316 is formed on the outer wall of the fixing block 315. A rotating shaft 317 is rotatably connected to the inner wall opposite to the positioning groove 316. A sliding wheel 318 is installed on the outer wall of the rotating shaft 317. A pulling steel rope 314 is slidably connected to the outer wall of the sliding wheel 318. One end of the pulling steel rope 314 extends to one side of the sliding wheel 318 and is connected to a wire reel 306. When the transmission end of the gearbox 304 drives the wire reel 306 to rotate, the wire reel 306 rotates and drives the carbon steel wire pulling steel rope 314 to contract, while the pulling steel rope 314 slides on the outer wall of the sliding wheel 318.

[0035] A support column 308 is installed on the outer wall of the fixed housing 301. An installation groove 309 is formed on the outer wall of the support column 308. A rotating shaft 310 is rotatably connected to the inner wall of the mounting groove 309. A fixing block 311 is installed on the outer wall of the rotating shaft 310. A fixing groove 312 is formed on the outer wall of the fixing block 311. A fixing rod 313 is installed on the inner wall of the fixing groove 312. A pulling steel cable 314 is installed on the outer wall of the fixing rod 313. Under the action of the pulling steel cable 314, one end of the pulling steel cable 314 applies tension to the fixing rod 313. The fixing block 315 and the support column 308 are perpendicular to each other. The straight structure, with the top of the fixing block 315 higher than the top of the support column 308, makes it easier for one end of the fixing block 311 to be subjected to tension when the steel rope 314 pulls the fixing rod 313. The connection between the rotating shaft 317 and the sliding wheel 318 is a rotatable connection. The steel rope 314 is made of carbon steel wire, resulting in higher structural strength. Simultaneously, the fixing rod 313 drives the fixing block 311 to rotate on the outer wall of the rotating shaft 310. The rotatable connection between the rotating shaft 310 and the fixing block 311, along with the grooved cross-section of the fixing block 311, contributes to this structural strength. This design ensures that the groove structure of the fixing block 311 is vertically upward, facilitating the clamping of the rebar cage onto the inner wall of the fixing block 311 for fixation. When the rebar cage is lengthened and needs to be lowered, simply turn on the switch of the control panel 305. This causes the control panel 305 to control the reel motor 303 to rotate in the opposite direction, causing the pulling steel rope 314 to lose tension on the fixing rod 313. Consequently, the fixing block 311 loses tension on one side, and the weight of the rebar cage presses down on the fixing block 311, causing it to flip on the outer wall of the rotating shaft 310. The fixing block 311 then loses its tension on one side. The device provides support for the reinforcing cage. Multiple sets of fixing blocks 2 are located on the outer wall of the mounting plate 1, with equidistant array spacing between them. The arc-shaped mounting plate 1 facilitates installation and future replacement and maintenance. The equal distance between the fixing blocks 2 also facilitates the installation and disassembly of the fixing components 3. This simplifies the installation and disassembly of the device, thus solving the problem of needing to install a fixing frame before lowering the reinforcing cage. During the lowering process, the fixing frame cannot be adjusted or replaced, and after the reinforcing cage is lengthened, it needs to be disassembled. Existing fixing frames are not easily disassembled.
