[0001] The utility model relates to the technical field of building construction, and particularly relates to a multi-point synchronous support type frame bridge. Background Technique

[0002] A frame bridge is a place where a water channel passes through a road. In order not to interfere with traffic, a frame bridge built under the road surface allows water to flow under the road and then turn up to the ground. Its shapes include tubular, box-shaped, arched, etc. However, the existing frame bridges still have deficiencies. Specifically, the support structure of the existing frame bridges cannot be adjusted, and the support effect is poor.

[0003] Therefore, a multi-point synchronous support type frame bridge is needed to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-point synchronous support type frame bridge to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A multi-point synchronous support type frame bridge includes a frame bridge body, and a support mechanism is arranged at the bottom of the frame bridge body;

[0007] The support mechanism includes a guide rod fixedly connected to the bottom of the frame bridge body. A support plate is slidably connected to the outer wall of the guide rod. A support rod is fixedly connected to the bottom of the support plate. A fixed sleeve is slidably connected to the outer wall of the support rod and below the support plate. A piston plate is fixedly connected to the bottom end of the support rod and inside the fixed sleeve. A liquid inlet pipe is fixedly connected to the inside of the fixed sleeve and below the piston plate. A one-way valve is fixedly connected to the inside of the liquid inlet pipe. An oil storage cylinder is fixedly connected to the outer wall of the liquid inlet pipe and outside the fixed sleeve. A return pipe is fixedly connected to the outer wall of the oil storage cylinder and behind the liquid inlet pipe. A stop valve is installed on the outer wall of the return pipe. A delivery pump is fixedly connected to the outer wall of the liquid inlet pipe and near the oil storage cylinder.

[0008] As a preferred scheme of the utility model, multiple groups of the support mechanisms are provided, and the frame bridge body is made of concrete casting.

[0009] As a preferred scheme of the utility model, the guide rod, the support plate and the support rod are all made of stainless steel. Multiple groups of the guide rod, the support rod, the fixed sleeve and the oil storage cylinder are provided. The connection modes of the oil storage cylinder, the delivery pump and the fixed sleeve are all fixed connections.

[0010] As a preferred scheme of the utility model, the liquid inlet pipe penetrates through the fixed sleeve and extends into the oil storage cylinder, and the one-way valve only allows hydraulic oil to flow into the fixed sleeve.

[0011] As a preferred solution of the present utility model, the return pipe penetrates through the oil storage cylinder and extends into the fixed sleeve, and the piston plate is slidably connected to the fixed sleeve.

[0012] As a preferred solution of the present utility model, both the oil storage cylinder and the fixed sleeve store hydraulic oil, and the guide rod penetrates through and extends outside the support plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, by designing a multi-point synchronous support type framed bridge, the support mechanism in the device is used to support the framed bridge body. The framed bridge body is installed at a suitable position, and then the delivery pump is started. The delivery pump injects the hydraulic oil in the oil storage cylinder into the fixed sleeve through the liquid inlet pipe. The hydraulic oil entering the fixed sleeve will push the piston plate and the support rod upward. The upward moving support rod drives the support plate to rise, and the support plate will abut against the framed bridge body, thereby supporting the framed bridge body. When it is necessary to lower the height of the support plate, the stop valve is opened, and the hydraulic oil in the fixed sleeve flows back into the oil storage cylinder through the return pipe. The hydraulic oil pressure in the fixed sleeve decreases, and the piston plate and the support rod drive the support plate to move downward, reducing the height of the support plate, solving the problem that the support structure of the existing framed bridge cannot be adjusted and the support effect is poor.

[0024] A multi-point synchronous support type frame bridge, including a frame bridge body 1, and a support mechanism 2 is arranged at the bottom of the frame bridge body 1;

[0025] In this embodiment, referring to Figure 2 and Figure 3 , the support mechanism 2 includes a guide rod 201 fixedly connected to the bottom of the frame bridge body 1. The outer wall of the guide rod 201 is slidably connected with a support plate 202. The bottom of the support plate 202 is fixedly connected with a support rod 203. The outer wall of the support rod 203 is slidably connected with a fixed sleeve 204 below the support plate 202. The bottom end of the support rod 203 is fixedly connected with a piston plate 205 inside the fixed sleeve 204. A liquid inlet pipe 206 is fixedly connected below the piston plate 205 inside the fixed sleeve 204. A one-way valve 207 is fixedly connected inside the liquid inlet pipe 206. An oil storage cylinder 208 is fixedly connected to the outer wall of the liquid inlet pipe 206 outside the fixed sleeve 204. A return pipe 209 is fixedly connected to the outer wall of the oil storage cylinder 208 on the back of the liquid inlet pipe 206. A stop valve 210 is installed on the outer wall of the return pipe 209. A delivery pump 211 is fixedly connected to the outer wall of the liquid inlet pipe 206 near the position of the oil storage cylinder 208;

[0026] Among them, the guide rod 201, the support plate 202, and the support rod 203 are all made of stainless steel. There are multiple groups of the guide rod 201, the support rod 203, the fixed sleeve 204, and the oil storage cylinder 208. The connection methods of the oil storage cylinder 208, the delivery pump 211, and the fixed sleeve 204 are all fixed connections. The liquid inlet pipe 206 penetrates through the fixed sleeve 204 and extends into the oil storage cylinder 208. The one-way valve 207 only allows hydraulic oil to flow into the fixed sleeve 204.

The guide rod 201 penetrates and extends outside the support plate 202. Start the delivery pump 211. The delivery pump 211 injects the hydraulic oil in the oil storage cylinder 208 into the fixed sleeve 204 through the liquid inlet pipe 206. The hydraulic oil entering the fixed sleeve 204 will push the piston plate 205 and the support rod 203 to move upward. The upward-moving support rod 203 drives the support plate 202 to rise. The support plate 202 will abut against the frame bridge body 1, thereby supporting the frame bridge body 1. When it is necessary to lower the height of the support plate 202, open the stop valve 210. The hydraulic oil in the fixed sleeve 204 flows into the oil storage cylinder 208 through the return pipe 209. The pressure of the hydraulic oil in the fixed sleeve 204 decreases. The piston plate 205 and the support rod 203 drive the support plate 202 to move downward, reducing the height of the support plate 202.

[0027] Working process of the present utility model: When the multi-point synchronous support type frame bridge designed by this solution is in operation, install the frame bridge body 1 at a suitable position, start the delivery pump 211. The delivery pump 211 injects the hydraulic oil in the oil storage cylinder 208 into the fixed sleeve 204 through the liquid inlet pipe 206. The hydraulic oil entering the fixed sleeve 204 will push the piston plate 205 and the support rod 203 to move upward. The upward-moving support rod 203 drives the support plate 202 to rise. The support plate 202 will abut against the frame bridge body 1, thereby supporting the frame bridge body 1. When it is necessary to lower the height of the support plate 202, open the stop valve 210. The hydraulic oil in the fixed sleeve 204 flows into the oil storage cylinder 208 through the return pipe 209. The pressure of the hydraulic oil in the fixed sleeve 204 decreases. The piston plate 205 and the support rod 203 drive the support plate 202 to move downward, reducing the height of the support plate 202.
