Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy project construction, in particular to a water conservancy construction guardrail. Background Art
[0002] Water conservancy project construction refers to a series of engineering activities to regulate, utilize and protect surface water and groundwater by building hydraulic structures such as reservoirs, embankments, channels, sluices and pumping stations in order to achieve the goal of rational allocation of water resources.
[0003] During the construction of water conservancy projects, it is necessary to build guardrails around the construction site. The water conservancy construction guardrail is a safety protection facility used at the water conservancy project construction site. Its main function is to isolate the construction area from the external environment, prevent people or animals from mistakenly entering the dangerous area, and ensure the safety of construction and passers-by. This type of guardrail is usually made of strong materials, such as steel or composite materials, and has sufficient stability and durability to withstand possible environmental impacts.
[0004] However, most of the guardrails on the market are fixed with bolts to the ground and are difficult to move. When a guardrail of this type is impacted, the impact is mainly borne by the bolts connecting the guardrail and the ground. The bolts can easily deform or even break due to the impact on the guardrail, which results in poor impact resistance of the guardrail. In view of this, a water conservancy construction guardrail is provided to overcome the above-mentioned defects. Utility Model Content
[0005] The utility model aims to solve the shortcomings in the prior art and proposes a water conservancy construction guardrail.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a water conservancy construction guardrail, comprising a guardrail frame, a guardrail is fixedly connected to the inner side of the guardrail frame, a hollow load-bearing shell is fixedly connected to the lower front end surface of the guardrail frame, threaded rods are rotatably connected to the lower left and right sides of the inside of the hollow load-bearing shell, a rotating rod is fixedly connected to the top of the threaded rod, a handle is fixedly connected to the top of the rotating rod, a movable plate is spirally connected to the outer side of the threaded rod, an extension plate is fixedly connected to the top end of the movable plate, a plug rod is fixedly connected to the bottom end of the extension plate, a triangular block is fixedly connected to the rear of the top of the extension plate, and a weight-increasing block is fixedly connected to the lower part of the inside of the hollow load-bearing shell.

The rear reinforcement can be performed when the guardrail frame is installed to prevent objects from rolling and colliding with the inner side of the guardrail frame, causing the guardrail frame to collapse.
[0008] As a further description of the above technical solution: the number of the threaded rods is two, and the threaded rods are distributed on the left and right sides of the hollow load-bearing shell. The interval distance between the threaded rods is two meters, which is suitable for guardrails with longer lengths. A group of threaded rods is set every two meters to improve the overall stability of the longer guardrail.
[0009] As a further description of the above technical solution: a slide groove is opened on the front side of the interior of the hollow load-bearing shell, and the width of the slide groove on the front side of the interior of the hollow load-bearing shell matches the width of the movable plate. The position of the slide groove on the front side of the interior of the hollow load-bearing shell is parallel to the position of the threaded rod, and the threaded rod can be driven downward by the threaded rod to insert into the pre-drilled hole, thereby avoiding the guardrail being fixed to the ground with bolts.
[0010] As a further description of the above technical solution: a longitudinal groove is provided on the front end face of the hollow load-bearing shell, and the width of the groove on the front end face of the hollow load-bearing shell matches the width of the rear end face of the triangular block. The cross-sectional shape of the triangular block is a right-angled triangle. The triangle is stable and can be used to support the contact point between the extension plate and the hollow load-bearing shell to avoid breakage caused by impact between the extension plate and the movable plate.
[0011] As a further description of the above technical solution: a block is engaged in the middle of the outer side of the railing, the rear end face of the block is fixedly connected to a sleeve, the front side of the sleeve is fixedly connected to a compression spring, the top end of the rear of the compression spring is fixedly connected to a push rod, the end of the push rod away from the compression spring is fixedly connected to a baffle, the rear end face of the baffle is fixedly connected to a buffer pad, and the rear inside of the sleeve is slidably connected to the outer side of the push rod.
[0012] As a further description of the above technical solution: the position of the block fixed on the railing is parallel to the position of the threaded rod, the area of the buffer pad is the same as the area of the rear end surface of the baffle, and the thickness of the buffer pad is half the thickness of the baffle, which can protect the railing to prevent the railing from being deformed by the impact of objects. At the same time, the buffer pad will also reduce the rebound force of the colliding object due to the hardness of the railing, thereby improving the safety of both the railing and the colliding object to a certain extent.
[0013] The utility model has the following beneficial effects:
[0014] The water conservancy construction guardrail designed by the utility model can be reinforced at the rear when the guardrail frame is installed through design coordination, so as to prevent objects from rolling and colliding with the inner side of the guardrail frame, causing the guardrail frame to collapse, thereby improving the overall impact resistance of the guardrail frame to a certain extent. At the same time, a triangular block is arranged between the extension plate and the hollow load-bearing shell for support, so as to prevent the guardrail frame from being broken due to the impact between the extension plate and the movable plate when being hit.
[0015] The water conservancy construction guardrail designed by the utility model can protect the railing through design coordination to prevent the railing from being deformed by the impact of objects. The railing has a supporting effect on the guardrail frame. When the railing is deformed, the overall load-bearing effect of the guardrail frame will also be reduced. Therefore, a buffer pad with a buffering effect is arranged at the rear of the railing, which can not only prevent the railing from being deformed due to the impact of objects on the railing, but also reduce the rebound impact force received by the colliding object due to the hardness of the railing, thereby improving the safety of both the railing and the colliding object to a certain extent.

[0028] Working principle:
[0029] When using the utility model, a hole is drilled on the ground of a set area, and the diameter of the drilled reserved hole is consistent with the cross-sectional diameter of the insertion rod 8. Then the guardrail frame 1 together with the hollow load-bearing shell 3 is placed on the upper rear side of the reserved hole in the ground. At this time, the insertion rod 8 is in a vertical state with the reserved hole. Then the operator turns the handle 5, and the handle 5 drives the threaded rod 14 to rotate in the hollow load-bearing shell 3 through the rotating rod 4. The movable plate 6 outside the threaded rod 14 drives the extension plate 7 and the insertion rod 8 to be inserted into the reserved hole. The triangular block 9 on the top of the extension plate 7 slides downward along the front end surface of the hollow load-bearing shell 3 until the insertion rod 8 is completely inserted into the reserved hole in the ground. Then the rotation of the handle 5 is stopped, and the guardrail frame 1 is installed. Then the baffle plate 12 is taken out, and the block 10 on the front end surface of the baffle plate 12 is sleeved on the guardrail The outer side of the railing 2 inside the frame 1 can be used normally after being fixed. When an object collides with the guardrail frame 1, the buffer pad 13 on the rear end face of the baffle 12 reduces the impact force between the colliding object and the railing 2, and then the baffle 12 moves forward due to the remaining impact force. The baffle 12 drives the top rod 17 to slide toward the front side of the sleeve 11, and the compression spring 16 is deformed. The rebound effect of the compression spring 16 can reduce most of the impact force. If the impact force is large and affects the guardrail frame 1, the impact force borne by the hollow load-bearing shell 3 is borne by the movable plate 6 and the extension plate 7, and a triangular block 9 is set between the extension plate 7 and the hollow load-bearing shell 3 for support to prevent the guardrail frame 1 from being broken due to the impact between the extension plate 7 and the movable plate 6 when it is hit.
