Description

Technical Field

[0001] This utility model relates to the field of bridge construction support technology, and in particular to an adjustable support device for bridge construction. Background Technology

[0002] As roads have become more complete, the distribution of basic infrastructure such as bridges and roads has become increasingly widespread. Bridges generally refer to structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also been extended to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient.

[0003] Bridge construction involves the use of support devices. Common bridge support adjustment devices often require independent support to accommodate different heights between bridges. Existing support devices, in order to improve structural strength, are generally made of welded supports. The welded joints are usually fixed connections that are difficult to disassemble. When reused, they need to be re-welded. Repeated welding can easily reduce the structural strength of the support and cause inconvenience in use. Utility Model Content

[0004] Therefore, it is necessary to address the issue that existing support devices, which typically rely on welded supports to improve structural strength, generally have fixed connections at the welded joints that are difficult to disassemble. When reused, they need to be re-welded, and repeated welding can easily reduce the structural strength of the support, causing inconvenience in use. Therefore, it is necessary to provide an adjustable support device for bridge construction.

[0005] An adjustable support device for bridge construction includes: a base, two limiting frames fixedly connected to the top of the base, a support frame movably connected inside the two limiting frames, and a support plate fixedly connected to the upper end of the two support frames;

[0006] The motor is mounted on the base and located on one side of the two limiting frames;

[0007] The transmission wheel is provided in two parts, which mesh with each other. The sides of the two transmission wheels that are far apart from each other are respectively meshed and connected to the outer walls of the two support frames. One of the transmission wheels and one output end of the motor are connected to a chain through a sprocket.

[0008] A limiting component is disposed in the middle of the chain and fixed to the two limiting frames.

[0009] In one embodiment, the two support frames are fixedly connected to the side away from each other with limiting teeth, and the two limiting frames are fixedly connected to the side away from each other with hooks, and the side of the two hooks that are close to each other engages with the limiting teeth.

[0010] In one embodiment, the plurality of the limiting teeth extend downward at an angle, and one side of the hook extends upward at an angle and fits against the underside of one of the limiting teeth.

[0011] In one embodiment, a fixing frame is movably sleeved on both sides of the shaft of the two drive wheels, and multiple fixing frames are respectively fixed on the side of the two limiting frames that are close to each other.

[0012] In one embodiment, the limiting assembly includes a first limiting gear disposed between the two limiting frames, both sides of the first limiting gear being meshed with the chain, a second limiting wheel being meshed with one side of the first limiting gear, and a limiting block being engaged with one side of the second limiting wheel.

[0013] In one embodiment, the chain is provided with limiting discs on both sides, and one of the limiting discs is fixed on the second limiting wheel.

[0014] In one embodiment, a bracket is movably connected to one side of the first limiting gear and one side of each of the two limiting discs, and one side of each bracket is fixed to one side of the outer wall of the two limiting frames. Beneficial effects

[0015] 1. The motor drives the sprockets to rotate via a coupling. There are two sprockets, which are fixed to the output end of the motor and the shaft of one of the drive wheels, respectively. The two sprockets are connected by a chain drive to rotate one of the drive wheels. The two drive wheels mesh and rotate. The outer wall of the support frame near the drive wheel has a toothed plate that can mesh with the drive wheel. The two rotating drive wheels drive the support frame to rise and fall through the meshing toothed plate. The two support frames slide inside the two limit frames respectively. The tops of the two support frames support the support plate to change the support height of the support plate, which facilitates the adjustment of the support height of the bridge parts and increases the installation efficiency of the bridge parts during the installation process.

[0016] 2. The first limiting gear consists of two gears that rotate coaxially and are fixed to the bracket. Two rotatable limiting discs are also mounted on the bracket. One gear meshes with the chain on both sides. When the chain moves, it drives the first limiting gear to rotate, and the two sides of the chain are limited by the two limiting discs, increasing the meshing degree between the chain and the first limiting gear. The other gear of the first limiting gear meshes with the second limiting wheel. One side of the second limiting wheel is limited by a limiting block fixed to the bracket and supported by a spring. When the limiting block engages with the second limiting wheel, the first limiting gear stops rotating. This design enhances the chain's limiting function, improves chain safety during use, and increases the stability of the support frame's lifting and lowering. Attached Figure Description

[0030] The following is combined Figures 1-5 This invention describes an adjustable support device for bridge construction.

[0031] In one embodiment, an adjustable support device for bridge construction includes: a base 100, a motor 500, a transmission wheel 700, and a limiting component 800. Two limiting frames 200 are fixedly connected to the top of the base 100. Support frames 300 are movably connected inside the two limiting frames 200. Support plates 400 are fixedly connected to the upper ends of the two support frames 300. The motor 500 is mounted on the base 100 and located on one side of the two limiting frames 200. Two transmission wheels 700 are provided, and the two transmission wheels 700 mesh with each other. The sides of the two transmission wheels 700 that are far apart from each other are respectively meshed with the outer walls of the two support frames 300. One of the transmission wheels 700 and one output end of the motor 500 are meshed with a chain 600 through a sprocket. The limiting component 800 is located in the middle of the chain 600 and is fixed on the two limiting frames 200.

[0032] In this embodiment, two limiting frames 200 are erected on the base 100, and two support frames 300 slide inside the two limiting frames 200 respectively. The support plate 400 is fixed above the two support frames 300, and the bridge equipment is supported above the support plate 400.

[0033] The motor 500 drives the sprockets to rotate via a coupling. Two sprockets are installed, one fixed to the output end of the motor 500 and the other to the surface of the shaft of one of the drive wheels 700. The two sprockets are connected by a chain 600, which drives one of the drive wheels 700 to rotate. The two drive wheels 700 mesh and rotate. The outer wall of the support frame 300 near the drive wheel 700 has a toothed plate that can mesh with the drive wheel 700. The two rotating drive wheels 700 drive the support frame 300 to rise and fall through the meshing toothed plate. The two support frames 300 slide inside the two limit frames 200 respectively. The tops of the two support frames 300 support the support plate 400, which is used to change the support height of the support plate 400, making it convenient to adjust the support height of the bridge parts and increasing the installation efficiency of the bridge parts during the installation process.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the two support frames 300 are fixedly connected to the side of each other that is far apart, and the two limit frames 200 are fixedly connected to the side of each other that is far apart. The two hooks 201 are engaged with the limit teeth 301 on the side that is close to each other. The multiple limit teeth 301 extend downward at an angle, and one side of the hook 201 extends upward at an angle and fits against the bottom of one of the limit teeth 301.

[0035] The hook 201 is hinged to the fixed plate. A telescopic column is installed below the fixed plate. The telescopic column is a mature product in the existing technology. The appropriate model can be selected according to the needs. The telescopic column limits the hook 201, causing the hook 201 to swing towards the side close to the limiting tooth 301. Multiple limiting teeth 301 are installed at equal intervals. The limiting teeth 301 that extend outward at an angle will limit the hook 201. When the support frame 300 falls, the hook 201 will lock the limiting teeth 301, increasing the stability of the support frame 300 when it rises and falls.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, fixed frames 701 are movably sleeved on both sides of the shaft of the two transmission wheels 700, and multiple fixed frames 701 are respectively fixed on the side of the two limit frames 200 that are close to each other.

[0037] The shaft of the transmission wheel 700 is inserted into the fixed frame 701 and rotates. The fixed frame 701 limits the transmission wheel 700, increasing the stability of the two transmission wheels 700 during rotation.

[0038] like Figure 3 , Figure 4 and Figure 5 As shown, the limiting assembly 800 includes a first limiting gear 801 disposed between two limiting frames 200. Both sides of the first limiting gear 801 are meshed with the chain 600. A second limiting wheel 803 is meshed with one side of the first limiting gear 801. A limiting block 804 is engaged with one side of the second limiting wheel 803. Limiting discs 802 are provided on both sides of the chain 600. One of the limiting discs 802 is fixed on the second limiting wheel 803. A bracket 805 is movably connected to one side of the first limiting gear 801 and the two limiting discs 802. One side of the bracket 805 is fixed to one side of the outer wall of the two limiting frames 200 respectively.

[0039] In this embodiment, the first limiting gear 801 consists of two gears that rotate coaxially and are fixed on the bracket 805. Two rotatable limiting discs 802 are also mounted on the bracket 805. One gear meshes with the chain 600 on both sides. When the chain 600 moves, it drives the first limiting gear 801 to rotate, limiting the chain 600 on both sides with the two limiting discs 802, thus increasing the meshing degree between the chain 600 and the first limiting gear 801. The other gear of the first limiting gear 801 meshes with the second limiting wheel 803. One side of the second limiting wheel 803 is limited by a limiting block 804, which is fixed on the bracket 805 and supported by a spring. When the limiting block 804 engages with the second limiting wheel 803, the first limiting gear 801 stops rotating, thus increasing the limiting function of the chain 600, improving the safety and stability of the chain 600 during use.

[0040] Working principle:

[0041] The motor 500 is driven by a coupling and two sprockets. The two sprockets drive the chain 600 to rotate, and the chain 600 drives the transmission wheel 700 to rotate through the sprockets. The two meshing transmission wheels 700 rotate simultaneously, causing the two support frames 300 to rise and fall inside the limit frame 200. The top of the two limit frames 200 drives the support plate 400 to support the bridge parts, which facilitates the adjustment of the support height of the bridge parts and increases the installation efficiency of the bridge parts during the installation process.

[0042] It should be noted that the motor 500 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the motor 500 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
