Description

Technical Field

[0001] The utility model relates to a precast pier construction falsework, belonging to the technical field of falsework. Background Technique

[0002] A falsework is a kind of mold, referring to a support frame that mainly plays a load-bearing and stress-bearing role. It is a special process equipment for facilitating the assembly and welding of mechanical equipment and is widely used in formwork engineering, steel structure installation engineering, and bridge engineering.

[0003] Chinese published patent (Publication No.: CN 215906591 U) discloses a new type of precast pier cap positioning falsework, including a bottom block. A groove is provided on the lower end surface of the bottom block, and openings are provided on both the front and rear sides of the groove. A plurality of equally spaced support plates are welded on the top of the groove. A through groove is provided at the lower end of each support plate. Installation plates are welded and combined on both sides of the bottom block. Two installation screw holes are longitudinally distributed on the installation plates. An array of installation square grooves is provided on the upper end surface of the bottom block, and the array of installation square grooves is longitudinally equally spaced on the end surface of the bottom block. Cross support plates are bolt-fixed at the installation square grooves. A positioning frame is combined on a group of horizontally arranged cross support plates. The overall design of the utility model is reasonable, with strong practicability. The overall structure is convenient for assembly, simple to operate, and realizes the stable and integral connection of the cap and the precast pier, having advantages such as good use effect;

[0004] Existing falseworks are usually assembled indoors and fixed to the top of the ground by bolts. After the pier is assembled in the falsework, the pier needs to be lifted and turned vertically before it can be installed at the bridge foundation. Due to the limited space indoors, after the pier is assembled, the falsework and the pier need to be moved out of the room before the subsequent vertical lifting work can be carried out. Since the pier and the falsework are heavy, a hoisting device is required to move them out of the room as a whole during the process, which will consume a lot of time and labor costs, and the process is relatively cumbersome and not convenient for operators to use.

[0005] Therefore, a precast pier construction falsework is proposed. Content of the Utility Model

[0016] Further preferably, mounting plates are fixedly installed on both the front and rear sides of the cross bar, fixing bolts are threadedly connected to the tops of the mounting plates, and the bottoms of the fixing bolts are threadedly connected to the inner surface of the top of the installation table.

[0017] The embodiment of the present utility model has the following advantages due to the adoption of the above technical solutions:

[0018] 1. By setting up a lifting mechanism in the present utility model, first, the output end of the bidirectional motor drives the second driving bevel gear to rotate. At this time, the second driven bevel gear rotates synchronously due to the rotation of the second driving bevel gear. At this time, the first bidirectional screw rod and the second bidirectional screw rod rotate synchronously due to the rotation of the second driven bevel gear, so that the first bidirectional screw rod and the second bidirectional screw rod rotate synchronously. At this time, the screw block moves inward due to the rotation of the first bidirectional screw rod and the second bidirectional screw rod. As the screw block moves, the turning rod turns downward, and through the turning of the turning rod, the entire moving mechanism moves downward. By lifting the moving mechanism, it can be avoided that when assembling the bridge pier, since the roller is in contact with the guide rail, the overall installation position of the equipment is unstable, thus affecting the assembly work of the bridge pier. By setting up the moving mechanism, through the lowering and lifting of the fixed frame, the roller moves to the surface of the guide rail. Subsequently, the output end of the DC motor drives the connecting rod to rotate. At this time, the first driving bevel gear drives the first driven bevel gear to rotate, and due to the rotation of the first driven bevel gear, the roller rotates synchronously. Thus, the moving mechanism, the lifting mechanism, and the jig body move to the right along the top of the guide rail through the first driven bevel gear, so that the jig body is moved out of the room, facilitating the subsequent removal of the bridge pier, improving the convenience of moving the jig body and the bridge pier out of the room, reducing the time and labor costs consumed when moving the whole out, and facilitating the operation of the operator.

[0019] II. By providing a second driven bevel gear, the present utility model can drive the output of the bidirectional motor, improving the convenience of the roller lifting. By providing a limiting rod, the movement of the screw block can be limited to prevent the screw block from shifting during movement, thereby affecting the roller lifting operation. By providing a first driven bevel gear, the DC motor can be driven, facilitating the rotation of multiple rollers by the DC motor, enabling the rollers to drive the entire device to move. By providing a cross bar, a chassis, and a mounting bracket, since the three are all fixed by bolts, the cross bar, chassis, and mounting bracket can be disassembled conveniently, improving the convenience of assembling the jig body. By providing a ground and a trough, since the height of the bottom of the trough cavity is the same as the height of the top of the ground, the entire device can be conveniently moved from the top of the installation table to the top of the ground, enabling the entire device to be moved outdoors. By providing rollers and guide rails, since the size inside the rollers matches the size of the top of the guide rails and is consistent in the vertical direction, the rollers will not wobble when rotating on the top of the guide rails, thus affecting the stability of the rollers when moving on the top of the guide rails. By providing a mounting plate and fixing bolts, the stability of the jig body installed on the top of the installation table can be improved, reducing the accidental collision due to external factors, which may cause the overall position of the jig body to shift, thereby affecting the assembly work of the bridge pier.

Specific embodiments

[0028] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and descriptions are considered to be exemplary in nature rather than restrictive.

[0029] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0030] Embodiment 1

[0031] As Figures 1-5 shown, the embodiment of the present utility model provides a precast pier construction tire rack, including a mounting table 1 and a ground 6. A tire rack body 4 is provided on the top of the mounting table 1. The tire rack body 4 includes a bottom frame 401. The bottom frame 401 is arranged on the top of the mounting table 1. Cross bars 402 are arranged on the top of the bottom frame 401. Mounting frames 403 are arranged on the front and rear sides of the top of the cross bars 402. Trough bodies 5 are formed on the front and rear sides of the top of the mounting table 1;

[0032] A lifting mechanism 3 is arranged on the left side of the bottom frame 401. The lifting mechanism 3 includes a bidirectional motor 301. The bidirectional motor 301 is fixedly installed on the left side of the bottom frame 401. Second driving bevel gears 302 are fixedly connected to the output ends on the front and rear sides of the bidirectional motor 301. First bidirectional screws 304 are movably connected to the front and rear sides of the bottom of the bottom frame 401. Second bidirectional screws 305 are movably connected to the right sides of the two first bidirectional screws 304. Screw blocks 306 are threadedly connected to the left and right sides of the surfaces of the two first bidirectional screws 304 and the six second bidirectional screws 305. Turning rods 307 are movably connected to the bottoms of the sixteen screw blocks 306;

[0033] A moving mechanism 2 is provided at the bottom of the sixteen flipping rods 307. The moving mechanism 2 includes a fixed frame 201. Both fixed frames 201 are movably connected to the bottom of the sixteen flipping rods 307. DC motors 202 are fixedly installed on the left sides of both fixed frames 201. Output ends of both DC motors 202 are fixedly connected to connecting rods 203. First driving bevel gears 204 are fixedly connected to the surfaces of both connecting rods 203. Rollers 206 are arranged inside both fixed frames 201. Guide rails 207 are fixedly installed at the bottoms of the inner cavities of both trough bodies 5.

[0034] By providing a lifting mechanism 3, first, the output end of a bidirectional motor 301 drives a second driving bevel gear 302 to rotate. At this time, a second driven bevel gear 303 synchronously rotates due to the rotation of the second driving bevel gear 302. At this time, a first bidirectional screw rod 304 and a second bidirectional screw rod 305 synchronously rotate due to the rotation of the second driven bevel gear 303. At this time, a screw block 306 moves inwards due to the rotation of the first bidirectional screw rod 304 and the second bidirectional screw rod 305. As the screw block 306 moves, the flipping rod 307 flips downwards, and through the flipping of the flipping rod 307, the whole moving mechanism 2 moves downwards. By providing the moving mechanism 2, through the lifting of the moving mechanism 2, it is possible to avoid the overall installation position of the equipment being unstable due to the rollers 206 being in contact with the guide rails 207 during the assembly of the bridge pier, thus affecting the assembly work of the bridge pier. Through the lowering and lifting of the fixed frame 201, the rollers 206 move onto the surfaces of the guide rails 207. Subsequently, the output end of the DC motor 202 drives the connecting rod 203 to rotate. At this time, the first driving bevel gear 204 drives the first driven bevel gear 205 to rotate, and due to the rotation of the first driven bevel gear 205, the rollers 206 synchronously rotate, so as to drive the moving mechanism 2, the lifting mechanism 3, and the jig body 4 to move to the right along the top of the guide rail 207, enabling the jig body 4 to be moved out of the room, facilitating the subsequent removal of the bridge pier, improving the convenience of moving the jig body 4 and the bridge pier out of the room, reducing the time and labor costs consumed when moving the whole out, and facilitating the use by the operator.

[0035] Embodiment 2

[0036] In one embodiment, second driven bevel gears 303 are movably connected to both the front and rear sides of the left side of the bidirectional motor 301. The surfaces of the two second driving bevel gears 302 mesh with the surfaces of the two second driven bevel gears 303. The left sides of the two first bidirectional screws 304 are fixedly connected to the right sides of the two second driven bevel gears 303. Limit rods 308 are fixedly installed on both the front and rear sides of the bottom of the chassis 401. The surfaces of the four limit rods 308 are slidably connected to the inner surfaces of the sixteen screw blocks 306. First driven bevel gears 205 are movably connected to the outer sides of the two fixed frames 201. The surfaces of the twelve first driven bevel gears 205 mesh with the surfaces of the twelve first driving bevel gears 204. The outer sides of the twelve rollers 206 are fixedly connected to the inner sides of the twelve first driven bevel gears 205. Seven crossbars 402 are all connected to the tops of the two chassis 401 by bolt threads. The bottoms of the fourteen mounting brackets 403 are all connected to the front and rear sides of the tops of the seven crossbars 402 by bolt threads. The bottom of the mounting table 1 is embedded in the ground 6. The height of the bottom of the inner cavity of the trough body 5 is the same as the height of the top of the ground 6. The size of the inner side of the roller 206 matches the size of the top of the guide rail 207, and the roller 206 is perpendicular to the top of the guide rail 207. Mounting plates 7 are fixedly installed on both the front and rear sides of the crossbar 402. Fixing bolts 8 are threadedly connected to the tops of the mounting plates 7. The bottoms of the fixing bolts 8 are threadedly connected to the inner surface of the top of the mounting table 1.

[0037] By setting the second driven bevel gear 303, the output of the bidirectional motor 301 can be transmitted, improving the convenience of the lifting of the roller 206. By setting the limiting rod 308, the movement of the screw block 306 can be limited to prevent the screw block 306 from shifting during movement, thereby affecting the lifting work of the roller 206. By setting the first driven bevel gear 205, the DC motor 202 can be transmitted, facilitating the rotation of multiple rollers 206 driven by the DC motor 202, so that the roller 206 can drive the entire device to move. By setting the cross bar 402, the chassis 401 and the mounting bracket 403, since they are all fixed by bolts, the cross bar 402, the chassis 401 and the mounting bracket 403 can be disassembled conveniently, improving the convenience of assembling the jig body 4. By setting the ground 6 and the trough 5, since the height of the bottom of the inner cavity of the trough 5 is the same as the height of the top of the ground 6, the entire device can be conveniently moved from the top of the installation table 1 to the top of the ground 6, so that the entire device can be moved outdoors. By setting the roller 206 and the guide rail 207, since the size of the inner side of the roller 206 matches the size of the top of the guide rail 207 and is consistent in the vertical direction, the roller 206 will not shake when rotating on the top of the guide rail 207, thus affecting the stability of the roller 206 when moving on the top of the guide rail 207. By setting the mounting plate 7 and the fixing bolts 8, the stability of the jig body 4 installed on the top of the installation table 1 can be improved, reducing the accidental collision due to external factors, resulting in the overall position of the jig body 4 shifting, thereby affecting the assembly work of the pier.

[0038] When the utility model works: First, the output end of the bidirectional motor 301 drives the second driving bevel gear 302 to rotate. At this time, the second driven bevel gear 303 rotates synchronously due to the rotation of the second driving bevel gear 302. At this time, the first double screw 304 and the second double screw 305 rotate synchronously due to the rotation of the second driven bevel gear 303. At this time, the screw block 306 moves inward due to the rotation of the first double screw 304 and the second double screw 305. As the screw block 306 moves, the turning bar 307 turns downward, and through the turning of the turning bar 307, the moving mechanism 2 moves downward. As the moving mechanism 2 moves, the roller 206 moves to the surface of the guide rail 207. Subsequently, the output end of the DC motor 202 drives the connecting rod 203 to rotate. At this time, the first driving bevel gear 204 drives the first driven bevel gear 205 to rotate, and due to the rotation of the first driven bevel gear 205, the roller 206 rotates synchronously. Thus, the moving mechanism 2, the lifting mechanism 3 and the jig body 4 are driven by the first driven bevel gear 205 to move to the right along the top of the guide rail 207, so that the jig body 4 is moved out of the room, completing the movement work of the entire device.

[0039] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described.
