[0003] Chinese Patent CN216786848U discloses a support device for bridge construction in bridge engineering. By setting bumps, when performing post-maintenance on the bridge main body, auxiliary support for the bridge is required. At this time, the device can be fixed below the bridge through the base. At this time, the hydraulic rod is started, and the hydraulic rod will gradually rise. When the upper surface of the support plate contacts the bridge main body, the bridge will squeeze the bump and cause it to drop. When the bump drops, it will squeeze the rotating block on the lower surface, and the rotating block will rotate accordingly. When the rotating block rotates, it will drive the lever to rotate and drive the multi-layer telescopic rod to extend. At this time, the operator can judge whether to close the hydraulic rod according to the extension of the multi-layer telescopic rod; however, during the support process, stones will hit and fall on the top of the hydraulic rod at the lower part of the bridge, causing damage to the top of the hydraulic rod.

[0022] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 1 to 4 , the utility model provides a technical solution:

[0024] A bridge substructure construction support adjusting device, comprising: a base 1, the bottom of the base 1 is clamped with four legs 2, the four legs 2 are distributed in a rectangle, the top of the base 1 is fixedly connected with a hydraulic adjustment seat 3, and the top end of the hydraulic adjustment seat 3 is fixedly connected with a top plate 4; a protection mechanism, the protection mechanism is arranged on the top of the base 1; wherein, the protection mechanism includes a protection frame 51 clamped on the top of the base 1, a groove is opened at the top of the protection frame 51, a sealing frame 52 is slidably connected to the groove of the protection frame 51, the top of the sealing frame 52 is fixedly connected with a protection block 53, the shape of the protection block 53 is a frustum of a cone, a plurality of springs 54 are fixedly connected to the relative ends of the sealing frame 52 and the protection frame 51, the top end of the protection block 53 is fixedly connected with a corrugated sleeve 55, the top end of the corrugated sleeve 55 is fixedly connected to the bottom end of the top plate 4, a reinforcing ring 56 is fixedly connected to the inner surface of the corrugated sleeve 55, a limiting block 511 is fixedly connected to one side of the sealing frame 52, the surface of the limiting block 511 is slidably connected to the inner wall of the protection frame 51, and handles 512 are fixedly connected to one side of the protection frame 51 and the base 1 respectively.

[0025] The top end of the hydraulic adjustment seat 3 penetrates and extends out of the inner wall of the protection block 53, and the top plate 4 and the hydraulic adjustment seat 3 can be fixed by threads. The specific fixing method is selected according to actual needs and will not be elaborated here. The protection frame 51, the sealing frame 52, the protection block 53 and the corrugated sleeve 55 are all rubber components.

[0026] During the construction of the lower structure of the bridge, a support adjusting device is required to support the formwork. Through the handle 512, the base 1 is placed on the formwork to be supported. The hydraulic adjusting seat 3 is manually activated, and when the top plate 4 moves upward, the corrugated sleeve 55 is stretched and abuts against the surface of the formwork. When the height of the formwork needs to be adjusted, the hydraulic adjusting seat 3 can be continuously opened, so that the top plate 4 pushes the formwork upward to a suitable position. The hydraulic adjusting seat 3 is manually closed to enable the support adjusting device to support and adjust the formwork. When stones fall and impact on the protective block 53 during the construction of the lower part of the bridge, the protective block 53 and the plugging frame 52 are forced to move downward, and the elastic force of the spring 54 pushes the plugging frame 52 and the protective block 53 upward, causing the stones on the protective block 53 to fall off. The plugging frame 52 blocks the stones from splashing onto the top of the hydraulic adjusting seat 3, the protective frame 51 blocks the stones from impacting on the side of the hydraulic adjusting seat 3, and the corrugated sleeve 55 and the reinforcing ring 56 block the stones from impacting on the upper end of the hydraulic adjusting seat 3.

[0027] As Figure 4 shown, magnetic holes 57 are provided at the upper ends of the surfaces of the legs 2 and the lower ends of the surfaces of the protective frames 51. When the legs 2 are inserted into the bottom of the base 1, the magnetic holes 57 of the legs 2 and the magnetic holes 57 of the protective frames 51 are on the same horizontal line. An insertion groove is provided on the side wall of the base 1, and a plurality of magnetic blocks 58 are slidably connected to the insertion groove of the base 1. The surface of the magnetic block 58 is clamped to the inner wall of the magnetic hole 57 and attracts with opposite poles. That is, the magnetic block 58 sequentially passes through the insertion groove of the base 1, the magnetic hole 57 of the leg 2, and the magnetic hole 57 of the protective frame 51 from the outside to the inside. Two moving frames 59 are slidably connected to the inner wall of the base 1. The front end of the magnetic block 58 is fixedly connected to the rear end of the moving frame 59. A positioning block 510 is slidably connected to the front end of the protective frame 51. A clamping groove is provided at the top of the moving frame 59, and the surface of the positioning block 510 is clamped to the inner wall of the clamping groove of the moving frame 59.

[0028] When the leg 2 needs to be replaced, the positioning block 510 is pulled upward to move it away from the lower moving frame 59. The lower moving frame 59 is pulled to move the magnetic block 58 away from the magnetic hole 57, releasing the positioning state of the leg 2 on the base 1. The handle 512 is lifted to simultaneously disengage the four legs 2 from the base 1, and then the leg 2 to be used can be replaced.

[0029] The working principle of the above-mentioned support adjusting device for the construction of the lower structure of the bridge is as follows:

[0030] In use, place the base 1 on the template to be supported through the handle 512. Manually activate the hydraulic adjusting seat 3 to move the top plate 4 upward to stretch the corrugated sleeve 55 and press it against the surface of the template. Manually close the hydraulic adjusting seat 3 so that the support adjusting device supports the template. When stones fall and impact on the protection block 53 during the construction of the lower part of the bridge, the protection block 53 and the blocking frame 52 are forced to move downward, and the elastic force of the spring 54 pushes the blocking frame 52 and the protection block 53 upward to shake off the stones on the protection block 53. The blocking frame 52 blocks the stones from splashing onto the top of the hydraulic adjusting seat 3, the protection frame 51 blocks the stones from impacting on the side of the hydraulic adjusting seat 3, and the corrugated sleeve 55 and the reinforcing ring 56 block the stones from impacting on the upper end of the hydraulic adjusting seat 3.

[0031] It should be noted that in the above description, the hydraulic adjusting seat 3, the magnetic block 58, the magnetic hole 57, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the hydraulic adjusting seat 3 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0032] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
