Utility model content

[0005] The utility model aims at providing a bridge foundation pit support device that can be simply disassembled.

[0006] In order to realize the first purpose of the utility model, the bridge foundation pit support device provided by the utility model comprises a bottom plate and a vertical plate which are perpendicular to each other, and the bottom plate and the vertical plate are connected through a detachable mechanism; the detachable mechanism comprises a first detachable component arranged on the bottom plate and a first groove arranged on the vertical plate, and the first detachable component is arranged in the first groove; the first detachable component is provided with a second groove, a first elastic component is arranged in the second groove, a first end of the first elastic component is fixed to the top wall of the second groove, and a second end of the first elastic component is connected with a first limiting block; a first through hole is arranged on the first groove, the opening direction of the first through hole corresponds to that of the second groove, and the first limiting block is clamped in the first through hole.

[0007] As can be seen from the above scheme, during installation of the base plate and the upright plate, the first detachable component is inserted into the first groove. Under the elastic force of the first elastic component, the first limiting block moves towards the first through hole, thereby engaging with the first through hole. When the bridge foundation pit support device is no longer in use, the first limiting block can be pressed under the first through hole, at which point the first elastic component is compressed, and the base plate and the upright plate can be separated. The detachable mechanism of this utility model makes the base plate and the upright plate easy to disassemble, reducing the effort and time of disassembly personnel during installation and disassembly.

[0008] In a further embodiment, a guide slope is provided on the first limiting block in the direction close to the first through hole.

[0009] Therefore, it can be seen that by providing a guide slope on the first limiting block near the first through hole, and by setting the guide slope away from the base plate, the base plate and the upright plate do not need to be pressed against the compression direction of the first elastic component during installation. When the first detachable component is inserted into the first groove, the first limiting block is pressed against the compression direction of the first elastic component along the guide slope, thereby completing the installation. This reduces the effort and time of the disassembly personnel during installation and disassembly.

[0010] In a further embodiment, a first connecting component is provided above the base plate, and a support rod is movably connected to the first connecting component. The support rod moves close to the upright plate. The first end of the support rod is movably connected to the first connecting component, and a push plate is provided at the second end of the support rod. The push plate is arranged parallel to the push plate, and a baffle is also provided above the baffle.

[0011] Therefore, the support rod provides support to the side of the upright plate. The first connecting assembly is connected to the support rod via a pin, allowing the support rod to rotate along the pin.

[0012] In a further embodiment, the upright plate is also provided with a second connecting component, which has a protrusion and a snap-fit ​​part. The protrusion is located on the first side of the upright plate, and the snap-fit ​​part is located on the second side of the upright plate.

[0013] It can be seen that by setting up protrusions and snap-fit ​​parts, two adjacent bridge foundation pit support devices can be connected, enabling multiple vertical plates to form joint support for the bridge foundation pit, thus improving the support effect.

[0014] In a further embodiment, the snap-fit ​​portion includes a third groove, and the protrusion and the third groove are disposed in the same horizontal direction.

[0015] As can be seen, by setting the protrusion and the third groove in the same horizontal direction, two adjacent upright plates can be connected.

[0016] In a further embodiment, a fourth groove is provided on the protrusion; a second through hole is provided in the third groove, through which the connecting rod passes; a limiting part is provided at the first end of the connecting rod, and a second limiting block is fixedly connected to the second end of the connecting rod; the snap-fit ​​part also includes a second elastic component, the first end of the second elastic component abutting against the top wall of the third groove, and the second end of the second elastic component abutting against the second limiting block.

[0017] It can be seen that, through the cooperation of the connecting rod, the second elastic component and the second limiting block, the protrusion of the other upright plate is engaged in the fourth groove when it is inserted, so that the two upright plates do not easily separate.

[0018] In a further embodiment, the second limiting block has an arc surface in the direction of the opening of the third groove.

[0019] As can be seen, by providing an arc surface in the direction of the opening of the second limiting block near the third groove, when the protrusion of the other vertical plate is inserted into the third groove, it is not necessary to manually move the second limiting block upwards to insert the protrusion of the other vertical plate. The protrusion of the other vertical plate can be directly inserted into the third groove. At this time, the protrusion of the other vertical plate presses against the second limiting block, and the second limiting block moves upwards, thereby completing the connection of the two vertical plates.

[0020] In a further embodiment, the locking part of the bridge foundation pit support device is locked with the protruding part of another bridge foundation pit support device.

[0021] As can be seen, by engaging the snap-fit ​​part with the protrusion of another bridge foundation pit support device, the connection of the two bridge foundation pit support devices is completed, enabling multiple vertical plates to form a joint support for the bridge foundation pit, thus improving the support effect.

[0022] In a further design, a ground cone is also installed beneath the base plate.

[0023] This shows that the ground cone can be driven into the soil to fix the base plate. Attached Figure Description

The first detachable component is provided with a first elastic component and a first limiting block connected to the first elastic component. The first groove is provided with a first through hole. The first detachable component is locked in place by the first limiting block and the first through hole. This detachable mechanism is relatively easy to install and disassemble, reducing the effort and time of disassembly workers.

[0031] See Figure 1 and Figure 2 The bridge foundation pit support device in this embodiment is provided with a base plate 11 and a vertical plate 12, which are vertically and detachably connected by a detachable mechanism. A ground cone 16 is also provided below the base plate 11, which can be driven into the soil to fix the base plate 11.

[0032] A first connecting assembly 13 is provided above the base plate 11, and a support rod 14 is movably connected to the first connecting assembly 13. The support rod 14 moves close to the upright plate 12. Specifically, the support rod 14 is an electric actuator. The first end of the support rod 14 is movably connected to the first connecting assembly 13, and the second end of the support rod 14 is provided with a push plate 15. A baffle 16 is also provided above the push plate 15. The support rod 14 and the push plate 15 support the side of the upright plate 12. The first connecting assembly 13 and the support rod 14 are connected by a pin (not shown in the figure), allowing the support rod 14 to rotate along the pin. The push plate 15 and the support rod 14 are connected by a movable shaft 151, allowing the angle of the push plate 15 to be freely adjusted. The baffle 16 restricts the push plate 15 from the top, preventing the push plate 15 from moving upward and losing its supporting function for the upright plate 12. The baffle 16, the first connecting assembly 13, the support rod 14, and the push plate 15 are provided in a one-to-one correspondence. Specifically, in this embodiment, two baffles 16, two first connecting components 13, two support rods 14, and two push plates 15 are provided to ensure that the support rods 14 and push plates 15 provide sufficient support to the sides of the upright plate 12.

[0033] See Figure 4 The detachable mechanism includes a first detachable component 111 disposed on the base plate 11 and a first groove 13 disposed on the upright plate 12, wherein the first detachable component 111 is disposed in the first groove 13.

[0034] The first detachable component 111 is provided with a second groove 1111, and a first elastic component 1112 is provided inside the second groove 1111. The first end of the first elastic component 1112 is fixed to the top wall of the second groove 1111, and the second end of the first elastic component 1112 is connected to a first limiting block 1113. A first through hole 14 is provided on the first groove 13, and the opening direction of the first through hole 14 corresponds to that of the second groove 1111. The first limiting block 1113 is engaged in the first through hole 14. A guide slope is provided on the first limiting block 1113 near the first through hole 14.

[0035] During installation, the base plate 11 and the upright plate 12 do not need to be pressed against the compression direction of the first elastic member 1112. When the first detachable member 111 is inserted into the first groove 13, the first limiting block 1113 is pressed against the compression direction of the first elastic member 1112 along the guide slope, thereby completing the installation.

[0036] When the bridge foundation pit support device of this embodiment is finished, the first limiting block 1113 can be pressed under the first through hole 14. At this time, the first elastic component 1112 is compressed, and the base plate 11 and the upright plate 12 can be separated. The detachable mechanism of this utility model makes it easy to disassemble the base plate and the upright plate, reducing the effort and time of the disassembly workers during installation and disassembly.

[0037] See Figure 3 and Figure 5 In this embodiment, the upright plate 12 of the bridge foundation pit support device is also provided with a second connecting component. The second connecting component is provided with a protrusion 125 and a snap-fit ​​portion. The protrusion 125 is provided on the first side of the upright plate, and the snap-fit ​​portion is provided on the second side of the upright plate. The snap-fit ​​portion includes a third groove 121, and the protrusion 125 and the third groove 121 are arranged in the same horizontal direction.

[0038] A fourth groove 1251 is provided on the protrusion. A second through hole 1211 is provided in the third groove 121, through which the connecting rod 1221 passes. A limiting part 1224 is provided at the first end of the connecting rod 1221, and a second limiting block 1223 is fixedly connected to the second end of the connecting rod 1221. The locking part also includes a second elastic member 1222, which is sleeved on the outside of the connecting rod 1221. The first end of the second elastic member 1222 abuts against the top wall of the third groove 121, and the second end of the second elastic member 1222 abuts against the second limiting block 1223. The second limiting block 1223 has an arc surface near the opening of the third groove 121. The locking part of this bridge pit support device locks with the protrusion of another bridge pit support device. The second elastic member 1222 is a spring.

[0039] When the protrusion of the upright plate of the other bridge foundation pit support device is inserted into the third groove 121 on the upright plate of the bridge foundation pit support device of this embodiment, it is not necessary to manually move the second limiting block 1223 upward to insert the protrusion of the other upright plate. The protrusion of the other upright plate can be directly inserted into the third groove 121. At this time, the protrusion of the other upright plate presses the second limiting block 1223, and the second limiting block 1223 moves upward. When the protrusion of the other upright plate is fully inserted, the second limiting block 1223 moves into the fourth groove of the protrusion of the other upright plate under the elastic force of the second elastic member 1222, thereby completing the connection of the two upright plates.

[0040] In this embodiment, when the bridge foundation pit support device is installed, the first detachable component 111 is inserted into the first groove 13, and the first limiting block 1113 is pressed along the guide slope towards the compression direction of the first elastic component 1112. When the first detachable component 111 is inserted into the first groove 13, the first limiting block 1113 moves towards the first through hole 14 under the elastic force of the first elastic component 1112, so that the first limiting block is engaged in the first through hole 14.

[0041] The ground cone 16 is driven into the soil to fix the base plate 11. The support rod 14 is moved so that it pushes the push plate 15 to support the upright plate 12. The baffle 16 restricts the push plate 15 from above, preventing it from moving upward and losing its supporting function for the upright plate 12.

[0042] When multiple bridge pit support devices are needed to support the bridge pit together, the protrusion of the upright plate 12 of another bridge pit support device is directly inserted into the third groove 121 of the upright plate 12 of one bridge pit support device. At this time, the protrusion of the other upright plate 12 presses against the second limiting block 1223, and the second limiting block 1223 moves upward. When the protrusion of the other upright plate is fully inserted, the second limiting block 1223 moves into the fourth groove of the protrusion of the other upright plate 12 under the elastic force of the second elastic member 1222, thereby completing the connection of the two upright plates.

[0043] The detachable mechanism of this utility model makes it easy to disassemble the base plate and the upright plate, reducing the effort and time of disassembly workers during installation and disassembly.

[0044] The above is only a preferred embodiment of the present utility model, but the design concept of the utility model is not limited thereto. Without departing from the concept of the present utility model, more other equivalent embodiments may be included. Those skilled in the art can make various obvious changes, readjustments and substitutions without departing from the protection scope of the present utility model.
