Description

Technical Field

[0001] This utility model relates to the technical field of bridge construction, and in particular to a bracket for bridge construction. Background Technology

[0002] A bridge is generally a structure built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, the term "bridge" has also been extended to refer to a building that crosses mountain streams, adverse geological conditions, or meets other transportation needs to make travel more convenient. During the construction of a bridge, brackets are usually used to support its bottom to prevent the bridge from collapsing.

[0003] Currently, most existing bridge construction brackets have simple structures. When the bracket's support force is insufficient, it cannot provide an alarm, which may lead to accident risks due to insufficient support force. Moreover, existing bridge construction brackets are all one-piece structures, which makes it difficult to adjust their height, resulting in poor practicality. Utility Model Content

[0004] This utility model provides a bracket for bridge construction, which facilitates the monitoring of the bracket's support force and the convenient adjustment of the support height.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A bridge construction bracket includes a base and a support plate, wherein the support plate is disposed above the base;

[0007] A support block is fixed to the lower end of the pallet, and a support plate is fixed to the lower end of the support block. A first bidirectional lead screw that rotates through the support block is provided above the support plate, and clamping plates are provided on both the left and right sides of the upper end of the pallet.

[0008] A lifting plate is provided below the support plate, a pressure alarm is installed on the outer side of the lower end of the lifting plate, and a pressure sensor is connected in the middle between the lifting plate and the support plate.

[0009] A fixing block is fixed in the middle of the bottom of the base, and a telescopic shaft is connected between the fixing block and the lifting plate. A lifting adjustment component is provided below the lifting plate.

[0010] Furthermore, each of the clamping plates is fixed with a push plate on its outer side, and each push plate is threadedly connected to the first bidirectional lead screw. Each of the support blocks is fixed with a guide plate at its left and right ends, and each guide plate slides through the adjacent push plate.

[0011] Furthermore, several telescopic rods are connected between the lifting plate and the support plate.

[0012] Furthermore, the pressure sensor is connected to the pressure alarm signal.

[0013] Furthermore, the lifting and adjusting assembly includes guide rails, adjusting blocks, inclined support plates, and a second bidirectional lead screw. The guide rails are provided in two positions and are distributed on the left and right sides, both fixed to the bottom of the base. The adjusting blocks are provided in two positions and are slidably connected to the two guide rails.

[0014] Furthermore, the inclined support plate is provided in two pieces, and one end of each inclined support plate is hinged to the upper end of the adjacent adjusting block, and the other end of each inclined support plate is hinged to the lower end of the lifting plate. The second bidirectional lead screw rotates through the base and the fixed block, and the adjusting blocks are threadedly connected to the second bidirectional lead screw.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting clamps, the bridge can be clamped, thus effectively ensuring the practicality of the bracket;

[0017] 2. By setting up pressure sensors and pressure alarms to detect the support force of the bracket, when the support force of the bracket is insufficient, the pressure alarm will sound to remind the staff, which is conducive to timely reinforcement and maintenance of the bracket and reduces the occurrence of accidents.

[0018] 3. By setting up a height adjustment component, the support height of the bracket can be easily adjusted, thereby facilitating stable support for bridges of various heights and better ensuring the practicality of the bracket. Attached Figure Description

Detailed Implementation

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] like Figure 1 , 2 As shown, in this embodiment, a base 1 and a support plate 2 are included. The support plate 2 is located above the base 1. A support block 9 is fixed to the lower end of the support plate 2. A support plate 4 is fixed to the lower end of the support block 9. A first bidirectional lead screw 8 is provided above the support plate 4 and rotates through the support block 9. Clamping plates 12 are provided on both the left and right sides of the upper end of the support plate 2. Push plates 11 are fixed to the outer side of the clamping plates 12. The push plates 11 are threadedly connected to the first bidirectional lead screw 8. Guide plates 10 are fixed to the left and right ends of the support block 9. The guide plates 10 slide through the adjacent push plates 11.

[0026] By setting the clamping plate 12, and by rotating the first bidirectional lead screw 8, the push plate 11 can be easily driven to slide along the guide plate 10. The push plate 11 facilitates the movement of the clamping plate 12, thus facilitating the clamping of the bridge through the clamping plate 12, thereby effectively ensuring the practicality of the bracket.

[0027] like Figure 1 As shown, in this embodiment, a lifting plate 3 is provided below the support plate 4, a pressure alarm 7 is installed on the outer side of the lower end of the lifting plate 3, a pressure sensor 5 is connected in the middle between the lifting plate 3 and the support plate 4, and several telescopic rods 6 are connected between the lifting plate 3 and the support plate 4. The pressure sensor 5 is signal-connected to the pressure alarm 7.

[0028] The support force of the bracket is detected by setting pressure sensor 5 and pressure alarm 7. When the bracket plate 2 supports the bridge, if the support force of the bracket is insufficient, the pressure alarm 7 will be preset with a pressure start value. The specific start value depends on the specific situation. Once the support force of the bracket is insufficient, the support plate 4 will press down to activate the pressure alarm 7 due to the excessive downward pressure of the bridge. After the pressure alarm 7 reaches the start value, it will control the pressure alarm 7 to sound an alarm. The alarm sound will then remind the staff to reinforce and maintain the bracket in a timely manner, which will help reduce the occurrence of accidents. In addition, multiple telescopic rods 6 provide auxiliary support for the support plate 4, which helps to ensure the balance of the support plate 4.

[0029] like Figure 1-3As shown, in this embodiment, a fixing block 17 is fixed in the middle of the bottom of the base 1. A telescopic shaft 13 is connected between the fixing block 17 and the lifting plate 3. A lifting adjustment assembly is provided below the lifting plate 3. The lifting adjustment assembly includes a guide rail 16, an adjusting block 15, an inclined support plate 14, and a second bidirectional lead screw 18. There are two guide rails 16, which are distributed left and right and fixed to the bottom of the base 1. There are two adjusting blocks 15, which are slidably connected to the two guide rails 16. There are two inclined support plates 14, and one end of each inclined support plate 14 is hinged to the upper end of the adjacent adjusting block 15. The other end of each inclined support plate 14 is hinged to the lower end of the lifting plate 3. The second bidirectional lead screw 18 rotates through the base 1 and the fixing block 17. The adjusting blocks 15 are threadedly connected to the second bidirectional lead screw 18.

[0030] A height adjustment component is installed, and the adjustment block 15 slides along the guide rail 16 by rotating the second bidirectional lead screw 18. The adjustment block 15 pushes the inclined support plate 14 to adjust the tilt angle of the inclined support plate 14. When the tilt angle of the inclined support plate 14 changes, the lifting plate 3 is pushed up or pulled down. Therefore, the lifting plate 3 will drive the support plate 4 and the support plate 2 to move up and down together. At the same time, the telescopic shaft 13 will extend and retract, which facilitates the convenient adjustment of the support height of the bracket, thereby facilitating the stable support of bridges of various heights. Thus, the support plate 2 can support bridges of various heights, better ensuring the practicality of the bracket.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementations of this utility model. In addition, other implementations are also included. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
