Description

Technical Field

[0001] This utility model belongs to the field of formwork support machine technology, specifically relating to a formwork support machine for highway bridges and culverts. Background Technology

[0002] A culvert is a water passage or pedestrian walkway built under the roadbed in highway construction to allow water to flow under the road or across roads of various sizes without obstructing traffic. It serves as an elevated passage for people, livestock, and vehicles, or as an irrigation canal for farmland. A culvert mainly consists of the culvert body, foundation, end walls, and purlins. Based on the principle of communicating vessels, culverts are commonly constructed using materials such as brick, stone, concrete, and reinforced concrete. Currently, culvert construction involves workers assembling formwork onto a formwork frame, then using support rods to hold the formwork in place to form the pouring cavity. After one section of pouring is completed, workers must remove the formwork and use cranes or other equipment to move the construction equipment to the next construction site. This repeated manual formwork closing and dismantling, and moving of the formwork frame, is labor-intensive, inefficient, and costly. Furthermore, most formwork frames have fixed dimensions, limiting their versatility to specific culvert sizes. Although existing formwork machines for highway bridges and culverts already exist, they still have certain functional defects. Firstly, existing formwork machines focus on the fixed support on both sides of the mold, while the ends and top are still not securely fixed, which can easily lead to the problem of the top of the mold expanding during the pouring process. Secondly, because existing formwork machines have walking components, they lack the stability of the overall structure when supporting the mold, and are prone to displacement of the whole machine.

[0003] In view of this, in order to solve the above-mentioned technical problems, this utility model proposes a formwork support machine for highway bridge culverts that improves the overall stability of the mold and avoids deformation and displacement during the casting process. Utility Model Content

[0004] This utility model provides a formwork support machine for highway bridges and culverts, which improves the overall stability of the mold and effectively avoids deformation and displacement of the mold during the pouring process. The specific solution is as follows: A formwork support machine for highway bridge culverts includes two crossbeams spaced apart along the length of the culvert. Two uprights are symmetrically arranged on the lower surfaces of the two crossbeams. Multiple uprights have wheels at their lower ends that can travel on tracks. Diagonal braces are provided between the lower parts of the uprights and the crossbeams. Side support columns are vertically arranged downwards at the center of the lower surfaces of the two crossbeams. Support components for supporting the inner and outer molds are provided on the side support columns and the two uprights. Reinforcing beams are symmetrically arranged between the two crossbeams. Clamping components for reinforcing the top of the mold are provided on the two reinforcing beams. Mold lifting components are provided on the lower surfaces of the two crossbeams.

[0005] Furthermore, the clamping assembly includes two clamping frames, a clamping cylinder, and a clamping rod. The two clamping frames are rotatably mounted on both sides of the reinforcing beam via mounting seats. The free ends of the two clamping frames are horizontally connected to clamping rods located on the sidewalls of the mold. The clamping cylinder is connected between the two clamping frames on the upper side of the mold via mounting lugs.

[0006] Furthermore, each of the two tracks is equipped with a braking assembly, which includes a brake cylinder, a rail-holding seat, a connecting rod, a pull rod, and a rail-holding block. The rail-holding seat is slidably mounted on the track, and a through groove communicating with the track is vertically opened in the middle of the rail-holding seat. The pull rod is hinged between the two side walls of the through groove, and the rail-holding block is hinged to the lower end of the pull rod. The brake cylinder is rotatably mounted on one side of the column, and the output end of the brake cylinder is hinged to the pull rod through a connecting lug. The connecting rod is located between the column and the rail-holding seat.

[0007] Furthermore, the support assembly includes a support cylinder, a cylinder connecting lug, and a ridge cylinder lug. The column and the side support column are each provided with two cylinder connecting lugs at intervals along their height direction. Support cylinders are rotatably mounted on the plurality of cylinder connecting lugs. The output ends of the plurality of support cylinders are rotatably connected to the outer side and the inner side of the template through the ridge cylinder lug.

[0008] Furthermore, a reinforcing support frame is connected between the top two sides of the two crossbeams.

[0009] Furthermore, the mold has multiple end cap mold horizontal push rods spaced apart at both ends along its height direction.

[0010] Furthermore, the mold lifting assembly includes lifting cylinders and lifting fixing lugs. Lifting cylinders are respectively hinged to the crossbeams above both sides of the mold, and lifting fixing lugs are respectively fixed to the mold sidewalls below the two lifting cylinders. The output ends of the two lifting cylinders are respectively hinged to the two lifting fixing lugs.

[0011] The beneficial effects of this utility model are: This utility model discloses a formwork support machine for highway bridges and culverts. It utilizes a reinforcing beam positioned between two crossbeams and a clamping assembly on the reinforcing beam. A clamping cylinder allows the two clamping frames to limit and clamp the sides of the mold, preventing deformation during pouring and ensuring pouring quality. A braking assembly, through a braking cylinder pulling a lever, causes the rail-holding block to abut against the rail, creating a locked state and stabilizing the formwork support machine on the rail, preventing mold displacement during pouring. Multiple end-cap mold horizontal support rods at both ends of the mold further limit and clamp the mold, ensuring stability during pouring. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] See Figure 1-5 A formwork support machine for highway bridge culverts includes two crossbeams 1 spaced apart along the length of the culvert. Two uprights 2 are symmetrically arranged on the lower surface of each crossbeam 1. The uprights 2 are detachably connected to the crossbeams 1 via U-shaped clamps. Multiple uprights 2 have wheels 4 at their lower ends that can travel on tracks 3. Diagonal braces 5 are provided between the lower parts of the uprights 2 and the crossbeams 1, with both ends of the diagonal braces 5 detachably connected to the uprights 2 and the crossbeams 1 via bolts. Side support columns 10 are vertically downwards at the middle of the lower surface of the two crossbeams 1. The side support columns 10 and the two uprights 2 are respectively equipped with inner molds for supporting the formwork 7. The support assembly 8 for the outer mold is provided. The support assembly 8 is designed to allow for adjustment of the width of the mold 7 to meet construction dimensions and to provide support for the mold 7. Reinforcing beams 11 are symmetrically provided between the two crossbeams 1 to further ensure the stability of the formwork support machine. Clamping assemblies 9 are provided on the two reinforcing beams 11 to reinforce the top of the mold 7. The clamping assemblies 9 are designed to allow for limiting and clamping the upper sides of the mold 7. Mold lifting assemblies are provided on the lower surfaces of the two crossbeams 1 to allow for raising the height of the mold 7 to meet construction requirements.

[0020] The clamping assembly 9 includes two clamping frames 901, a clamping cylinder 902, and a clamping rod 903. The two clamping frames 901 are rotatably mounted on both sides of the reinforcing beam 11 via mounting seats. The free ends of the two clamping frames 901 are horizontally connected to the clamping rods 903 located on the side walls of the mold 7. The clamping cylinder 902 is connected between the two clamping frames 901 on the upper side of the mold 7 via mounting lugs. Specifically, mounting seats are welded at intervals on both sides of the reinforcing beam 11. The upper ends of the two clamping frames 901 are rotatably connected to the mounting seats via shafts. The lower ends of the two clamping rods 903 are horizontally located on both sides of the mold 7. The clamping cylinders 902 are activated and deactivated to retract the two clamping frames 901, thereby pressing the two clamping rods 903 against the side walls of the mold 7 to form a limit, thus preventing deformation of the middle part of the mold 7 during the casting process and affecting the casting quality.

[0021] Braking assemblies 6 are respectively installed on the two tracks 3. Each braking assembly 6 includes a brake cylinder 601, a rail-holding seat 602, a connecting rod 603, a pull rod 604, and a rail-holding block 605. The rail-holding seat 602 is slidably mounted on the track 3. A through groove communicating with the track 3 is vertically opened in the middle of the rail-holding seat 602. The pull rod 604 is hinged between the two side walls of the through groove. The pull rod 604 is rotatably connected between the two side walls of the through groove via a shaft. The rail-holding block 605 is hinged to the lower end of the pull rod 604. The brake cylinder 601 is rotatably mounted on one side of the column 2. The output end of the brake cylinder 601 is hinged to the pull rod 604 via a connecting lug. The connecting rod 603 is set between the column 2 and the rail seat 602. Specifically, the structure of the track 3 is a groove type, and the upper two sides of the groove are horizontally provided with baffles. The rail seat 602 slides on the track 3, and the rail block 605 is a rectangular structure with a width slightly smaller than the width of the two sides inside the groove. When braking, the brake cylinder 601 is activated, which pushes the pull rod 604. At this time, the pull rod 604 pushes the rail block 605 to move and makes the bottom surface of the rail block 605 abut against the bottom surface of the groove on the track 3, so as to form a lock to meet the braking purpose and thus ensure the stability of the formwork machine on the track 3.

[0022] The support assembly 8 includes a support cylinder 801, a cylinder connecting lug 802, and a back cylinder lug 803. The column 2 and the side support column 10 are respectively provided with two cylinder connecting lugs 802 at intervals along their height direction. Support cylinders 801 are rotatably mounted on multiple cylinder connecting lugs 802. The output ends of multiple support cylinders 801 are rotatably connected to the outer side and the inner side of the template through the back cylinder lug 803. Specifically, when adjusting the distance between the outer mold and the inner mold of the mold 7, it is only necessary to start the support cylinders 801 on both the inner and outer sides.

[0023] A reinforcing support frame 12 is connected between the top two sides of the two crossbeams 1, and the reinforcing support frame 12 is provided to strengthen the two crossbeams 1.

[0024] Multiple end-capping mold push rods 13 are provided at intervals along the height direction at both ends of the mold 7. The mold 7 has ridges on both sides, and through holes suitable for the end-capping mold push rods 13 to pass through are opened on the ridges on both sides. The end-capping mold push rods 13 can further limit and clamp the two ends of the mold 7, further ensuring the stability of the mold 7 during casting.

[0025] The mold lifting assembly includes lifting cylinders 14 and lifting fixing lugs 15. Lifting cylinders 14 are hinged to the crossbeams 1 on both sides of the mold 7. Lifting fixing lugs 15 are fixed to the side walls of the mold 7 below the two lifting cylinders 14. The output ends of the two lifting cylinders 14 are hinged to the two lifting fixing lugs 15 respectively. Specifically, the lifting cylinders 15 are rotatably connected to the crossbeams 1 via U-shaped lugs and can rotate left and right. The output ends of the lifting cylinders 14 are also rotatably connected to the lifting fixing lugs 15. The lifting fixing lugs 15 are fixedly connected to the side of the mold 7 and can also rotate left and right on the lifting fixing lugs 15. The lifting cylinders 14 and the mold 7 are spaced apart so that the mold lifting assembly can adapt when the support assembly 8 adjusts the width of the mold 7. When it is necessary to raise the height of the mold 7, only the lifting cylinders 14 need to be controlled.

[0026] The working principle of this utility model: When using this formwork support machine, first activate the brake cylinder 601, which pushes the pull rod 604. The pull rod 604 then moves the rail clamping block 605, causing its bottom surface to abut against the bottom surface of the groove on the track 3, thus locking the machine for braking purposes and ensuring its stability on the track 3. Next, adjust the width of the template 7 as needed. This can be done by activating the support cylinders 801 on both sides of the template 7, making it wider or narrower. Then, cover the ends of the template 7 with the side plates and use the end-capping mold horizontal push rod 13 for limiting and fixing. Finally, control the clamping... The start and stop of the hydraulic cylinder 901 causes the two clamping frames 901 to retract, thereby causing the two clamping rods 903 to press against the side wall of the mold 7 to form a limit. At this time, the mold 7 can be poured. After the pouring of this section is completed and solidified, the end cap mold horizontal top rods 13 at both ends are removed to take the side plate. The clamping hydraulic cylinder 901 and the support hydraulic cylinder 801 are controlled to control the clamping rods 903 away from the side of the mold 7 and the side of the mold 7 away from the poured body. Then, the brake hydraulic cylinder 601 is controlled to pull the pull rod 604 to release the brake of the rail clamping block 605 on the rail. The formwork machine can then be pushed to carry out construction at the next construction site.
