Description

Technical Field

[0001] The utility model generally relates to the technical field of protective fences, and in particular to a railway line protective fence. Background Art

[0002] Fences are set up on both sides of the railway for protection to ensure safety. At present, in order to facilitate the construction of transport aircraft, most of the fences along the railway have been replaced by the original concrete fences with the current lightweight steel pipe railway fences. For example, the Chinese utility model patent with application number 2023226452724 discloses a sleeve-type strong connection railway safety protection fence, which adopts a support sleeve embedded in the ground through concrete, and the fence body is designed with support feet, which can be connected to the support sleeve through the first edge and the second edge. Through this setting method, the convenience of the fence installation process can be effectively improved and the construction efficiency can be improved.

[0003] However, since the legs of the fence body are fixedly connected by welding, and the support sleeves are pre-buried in the ground, the first edge and the second edge are respectively welded to the legs and the support sleeves, and the first edge and the second edge are locked by bolts. This connection method requires high pre-embedding accuracy of the two support sleeves corresponding to the two legs of a fence body. When the distance error between the two support sleeves is large, it is easy for the installation to fail.

[0004] On the other hand, due to the large size and weight of the fence body, a lifting device is needed to assist the construction. However, in some areas where the lifting device is difficult to reach, manual lifting is required. The large-sized fence body is difficult to lift, the labor intensity is high, and the risk factor is high. Utility Model Content

[0005] In view of the above problems, the present application provides a railway line protection fence to at least partially solve the technical problems existing in the prior art.

[0006] The utility model provides a railway line protection fence, comprising support columns arranged at intervals, and also comprising:

[0007] Fence components, each of the fence components includes two fence sub-bodies respectively hingedly connected to two adjacent support columns, the axis of the hinge shaft of the hinge position of the fence sub-body and the support column is vertically arranged, and a locking unit is arranged at one end of the two fence sub-bodies close to each other, and the two fence sub-bodies can be locked and connected by the locking unit.

[0008] Specifically, by dividing the fence assembly into two fence sub-bodies, and hingedly connecting the two fence sub-bodies to the support column through a hinge shaft, a single fence sub-body is light in weight and easy to construct during construction, and the fence sub-bodies are conveniently connected by connecting through the hinge shaft, and then the two fence sub-bodies can be rotated and locked through a locking unit. The construction is convenient and simple, and the safety factor is high.

[0009] Furthermore, the locking unit includes two lap plates and locking bolts which are respectively arranged on the two fence sub-bodies, and the two lap plates are both horizontally provided with strip holes, and the locking bolts pass through the two strip holes to lock and connect the two lap plates.

When the fence sub-body is connected to the support column, the fence sub-body only needs to be lifted, and the sleeve is sleeved on the hinge shaft to realize the connection between the fence sub-body and the support column. The connection method is simple and reliable. After the fence sub-body is installed on the support column, an anti-slip plate is installed. The anti-slip plate can limit the position of the sleeve in the vertical direction, thereby achieving the effect of preventing disassembly and theft.

[0013] Furthermore, the support column includes a first section pre-buried in the ground and a second section connected to the fence assembly, one of the ends of the first section and the second section is provided with a first connecting plate, and the other is provided with a second connecting plate, the first connecting plate is vertically provided with a screw rod, the second connecting plate is provided with a second strip hole for the screw rod to pass through, the end of the screw rod extending out of the second strip hole is threadedly connected with a locking nut, and the second strip hole is extended along the direction of the interval between two adjacent support columns.

[0014] Specifically, by configuring the support column to include a first section pre-buried in the ground and a second section arranged at the upper end of the first section, and connected by a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are connected by a screw and a second strip hole, so that the position of the second section can be adjusted in the spacing direction of the support column, further compensating for the positioning error of the support column, and making it easier to install.

[0015] Furthermore, the first connecting plate is provided with limit assemblies at both ends of the second strip hole, the limit assemblies include limit surfaces abutting against the ends of the second strip hole for limit, and the screw rod is located between the two limit assemblies.

[0016] Specifically, by setting two limiting components, after the first section and the second section are locked by the locking nut, the two ends of the second strip hole are limited by the limiting components, thereby avoiding the deviation of the second section and achieving effective positioning.

[0017] Furthermore, the limiting assembly includes a movable part that abuts against the end of the strip hole, a clamping plate arranged on the side of the movable part close to the screw rod, and a clamping bolt threadedly connected to the first connecting plate and providing a clamping force to the clamping plate.

[0018] Specifically, through this arrangement, the clamping plate can be pressed, and the second mating bevel can be used to apply a thrust to the first mating bevel, so as to push the limiting surface of the movable part against the end of the second strip hole. Through the cooperation of the second mating bevel and the first mating bevel, the movable part has an adjustment margin in the length direction of the second strip hole. Different sizes of movable parts can be used according to actual usage conditions, which can adapt to various connection conditions between the second section and the first section and increase the adjustment range.

[0019] Furthermore, a support member is provided on the clamping plate at a side of the clamping bolt close to the screw rod.

[0020] Furthermore, a limiting protrusion is provided at the end of the second strip-shaped hole, and a limiting groove cooperating with the limiting protrusion is provided on the limiting surface.

[0021] Specifically, by providing a limiting groove that is adapted to the limiting protrusion, the movable part can be limited in the axial direction of the screw rod to prevent the movable part from falling off.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Embodiment 1

[0036] The utility model provides a railway line protection fence, referring to Figure 1-Figure 3 As an embodiment, it includes support columns 1 arranged at intervals, and also includes:

[0037] The fence assembly 2, each of the fence assembly 2 includes two fence sub-bodies 21 respectively hingedly connected to the two adjacent support columns 1, the axis of the hinge shaft 22 at the hinge position of the fence sub-body 21 and the support column 1 is vertically arranged, and a locking unit 23 is arranged at one end of the two fence sub-bodies 21 close to each other, and the two fence sub-bodies 21 can be locked and connected by the locking unit 23.

[0038] Specifically, refer to Figure 1 The support column 1 is pre-buried in the ground, and hinge shafts are provided on the opposite sides of the support column, so that fence sub-bodies can be set on both sides. The fence component 2 is divided into two fence sub-bodies 21, and the two fence sub-bodies 21 are hingedly connected to the support column 1 through the hinge shaft 22. During construction, a single fence sub-body is light in weight and easy to construct, and the fence sub-body is conveniently connected by connecting the hinge shaft 22, and then the two fence sub-bodies are rotated and locked through the locking unit 23. The construction is convenient and simple, and the safety factor is high.

[0039] Further, as a specific implementation method, refer to Figure 1 , Figure 2 The locking unit 23 includes two lap plates 231 and locking bolts 230 which are respectively arranged on the two fence sub-bodies 21. The two lap plates 231 are both horizontally provided with strip holes 232. The locking bolts pass through the two strip holes to lock and connect the two lap plates.

[0040] Specifically, the lap plate 231 is welded to the fence sub-body 21, and the locking is simple and reliable by setting a strip hole 232 on the lap plate. The strip hole 232 can have a certain adjustment amount in the direction of two adjacent support columns, thereby compensating for the positioning error of the support column and making it easier to install.

[0041] Further, as a specific implementation method, refer to Figure 2 A first support plate 220 is arranged on the support column 1, and the hinge shaft 22 is vertically arranged on the first support plate 220. A sleeve 221 which is sleeved and matched with the hinge shaft 22 is arranged on the fence sub-body 21. An anti-slip plate 222 is also detachably and fixedly connected to the support column 1, and the anti-slip plate is located above the hinge shaft 22.

[0042] Specifically, by setting the hinge axis on the upper plate surface of the first support plate 220, the first support plate is welded to the support axis 1, and a sleeve is set on the fence sub-body. When the fence sub-body is connected to the support column, it is only necessary to lift the fence sub-body and sleeve the sleeve on the hinge axis to achieve the connection between the fence sub-body and the support column. The connection method is simple and reliable. After the fence sub-body is installed on the support column 1, the anti-slip plate 222 is installed. The anti-slip plate can limit the vertical position of the sleeve 221 to achieve the effect of anti-dismantling and anti-theft. As a specific implementation method, the anti-slip plate 222 is connected to a fixed plate 223, and the fixed plate is detachably fixed to the support column 1 by bolts, and the anti-slip plate is welded to the fixed plate 223.

[0043] Embodiment 2

[0044] The utility model provides a railway line protection fence as a specific implementation method, referring to Figure 4-Figure 8 , which is different from the first embodiment, is that the support column 1 includes a first section 1a pre-buried in the ground and a second section 1b connected to the fence assembly 2, one of the ends of the first section 1a and the second section is provided with a first connecting plate 11, and the other is provided with a second connecting plate 12, a screw rod 13 is vertically provided on the first connecting plate, and a second strip hole 14 for the screw rod to pass through is provided on the second connecting plate, and a locking nut 15 is threadedly connected to the end of the screw rod 13 extending out of the second strip hole 14, and the second strip hole 14 is extended along the direction of the interval between two adjacent support columns.

[0045] Specifically, the first connecting plate and the second connecting plate are connected to the first section 1a or the second section by welding. As a specific implementation, exemplarily, the second connecting plate is connected to the second section. By setting the support column 1 to include a first section 1a pre-buried in the ground and a second section arranged at the upper end of the first section, and connected by the first connecting plate and the second connecting plate, the first connecting plate and the second connecting plate are connected by a screw 13 and a second strip hole 14. The position of the second section can be adjusted in the spacing direction of the support column, further compensating for the positioning error of the support column, and making it easier to install.

[0046] Further, as a specific implementation method, refer to Figure 6-Figure 8 A limiting assembly 16 is provided at both ends of the second strip hole 14 on the first connecting plate 11 . The limiting assembly 16 includes a limiting surface 161 that abuts against the end of the second strip hole 14 for limiting the position. The screw rod 13 is located between the two limiting assemblies 16 .

[0047] Specifically, by setting two limiting components, after the first section and the second section are locked by the locking nut 15, the two ends of the second strip hole are limited by the limiting components, thereby avoiding the deviation of the second section and achieving effective positioning.

[0048] Further, as a specific implementation method, refer to Figure 6-Figure 8 The specific structure of the limiting assembly is as follows: the limiting assembly 16 includes a movable part 160 that abuts against the end of the strip hole, a clamping plate 162 arranged on the side of the movable part 160 close to the screw rod 13, and a clamping bolt 163 threadedly connected to the first connecting plate and providing a clamping force to the clamping plate. The movable part 160 is provided with a first mating inclined surface 1611 at one end close to the clamping plate, and the clamping plate is provided with a second mating inclined surface 1621 adapted to the first mating inclined surface. The limiting surface 161 is the end surface of the movable part 160.

[0049] Specifically, it can be understood that the second section can be fine-tuned in the spacing direction of the support columns. If the adjustment range is different, the axial offset distances of the second section and the first section are also different. Therefore, the distances of the clamping bolt 163 reaching the end of the strip hole are also different. Through this arrangement, the clamping plate can be clamped, and the second mating bevel can apply a thrust to the first mating bevel, thereby pushing the limiting surface of the movable part 160 against the end of the second strip hole. Through the cooperation of the second mating bevel and the first mating bevel, the movable part 160 has an adjustment margin in the length direction of the second strip hole. Different sizes of movable parts 160 can also be used according to actual usage. Different sizes of movable parts 160 refer to the dimensions along the length direction of the second strip hole. As a specific implementation method, the movable part 160 uses a rectangular block. The width of the rectangular block is equal to the width of the second strip hole. It can adapt to the various offset ranges between the second section and the first section and increase the adjustment range.

[0050] Further, as a specific implementation, the clamping plate is further provided with a support member 164 on one side of the clamping bolt close to the screw rod 13. Specifically, the end of the clamping plate is supported by the support member 164, and at this time, when the clamping bolt 163 is clamped, it can apply a clamping force to the first matching bevel through the second matching bevel, and push the movable member 16 to move and abut against the end of the second strip hole. Through this arrangement, the support member 164 of different heights can be adjusted according to actual use conditions.

[0051] Further, as a specific implementation, a limiting protrusion 141 is disposed at the end of the second strip-shaped hole 14 , and a limiting groove 1610 cooperating with the limiting protrusion 141 is disposed on the limiting surface 161 .

[0052] Specifically, by providing a limiting groove that is adapted to the limiting protrusion, the movable part can be limited in the axial direction of the screw rod 13 to prevent the movable part from falling off.
