Description

Technical Field

[0001] The utility model relates to the technical field of subway operation protection, and specifically, to a new safety device for subway operation. Background Technique

[0002] The subway is a rapid, high-capacity, electrically powered rail transit built in cities. The train runs on a fully enclosed line. The lines in the central urban area are basically located in underground tunnels, and the lines outside the central urban area are generally located on viaducts or on the ground. The subway is an urban rail transit system that covers various underground and above-ground exclusive rights of way, high density, and high capacity in urban areas. During the operation and use of the subway, it is often necessary to maintain and repair facilities and equipment. To prevent passengers or unauthorized personnel from straying in, it is necessary to use protective devices for isolation to maintain the subway operation.

[0003] The existing operation protection devices are inconvenient to use, have the defects of large volume and inability to be folded and stored, resulting in inconvenience for users to carry; and they do not have the function of height adjustment or width adjustment, and cannot meet complex and changeable usage scenarios.

[0004] For example, Chinese Patent No. CN214365394U discloses a protective alarm device for subway operation and maintenance. The protective alarm device improves the laying efficiency through the rotational connection between the inclined rods, between the inclined rods and the ear plates, and the clearance fit between the slider and the chute, has the advantages of small occupied space and easy storage, and has an automatic alarm warning function. However, this device still has certain defects. For example, it cannot be height-adjusted, that is, it cannot change the height of the main protective rod and the protective fence, and is not suitable for rich scenarios; and its foldable fence structure is relatively simple and the protection ability is insufficient.

[0005] In view of the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0006] In view of the problems in the related art, the utility model proposes a new safety device for subway operation to overcome the above technical problems existing in the existing related art.

[0007] For this reason, the specific technical solution adopted by the utility model is as follows:

[0008] A new safety device for subway operation includes two symmetrically arranged support columns. A cavity is opened inside the support columns. A threaded column is inserted through the bottom of the cavity. A base is arranged at the bottom end of the threaded column. An adjusting knob is sleeved on the outer circumference of the bottom of the threaded column; a plurality of equally spaced folding components are arranged between the two support columns, and a protective column is arranged between adjacent two folding components.

[0009] Furthermore, to improve the warning effect, the connecting buckle can be used to connect multiple operation protection devices, so as to maintain isolation for locations with a large range or distance. A warning light is provided at the top of the support column, and connecting buckles are provided at both the bottom and the top on the outer side of the support column.

[0010] Furthermore, to ensure the stability of the support column and prevent it from tilting and shaking on the outer side of the threaded column, a limiting column is provided at the top of the threaded column. The cavity and the limiting column are both cylindrical structures and have the same diameter. The diameter of the threaded column is smaller than that of the limiting column.

[0011] Furthermore, to connect two support columns and multiple protection columns, the folding function of the upper and lower groups of connecting rods in the folding assembly is utilized to realize the storage and deployment of the protection device. An upper fixing seat is provided at the top inside the support column, and a lower fixing seat is provided at the bottom inside the support column. The folding assembly includes a first upper connecting rod, a second upper connecting rod, a first lower connecting rod, and a second lower connecting rod. The first upper connecting rod and the second upper connecting rod are movably connected, and the first lower connecting rod and the second lower connecting rod are movably connected. A vertical connecting rod is provided between the intersection of the first upper connecting rod and the second upper connecting rod and the intersection of the first lower connecting rod and the second lower connecting rod. The two upper fixing seats are respectively movably connected to the first upper connecting rod and the second upper connecting rod, and the two lower fixing seats are respectively movably connected to the first lower connecting rod and the second lower connecting rod. The protection column is a U-shaped hollow structure, and the inner top of the protection column is respectively movably connected to the first upper connecting rod and the second upper connecting rod, and the inner bottom of the protection column is respectively movably connected to the first lower connecting rod and the second lower connecting rod.

[0012] Furthermore, to improve the warning effect of the protection device, reflective warning strips are provided on both the front and the back of the protection column.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. Through the support column with an internal cavity, the height adjustment of the overall structure can be realized by the action of the threaded column and the adjustment knob, which is convenient for carrying and transferring in the subway station and placing in various places, so as to meet more and more complex usage scenarios. Moreover, the adjustment is convenient and fast, the operation is simple, which can effectively save the workload and operation difficulty of the users and improve the operation and maintenance protection effect.

[0015] 2. By setting the foldable and retractable folding assembly and the protection column, the state switching between the foldable storage and the deployed protection of the protection device can be realized, effectively improving the portability and flexibility of the protection device. And in the deployed state, it has strong protection ability, that is, using multiple protection columns and reflective warning strips to achieve the functional purpose of warning and protection, avoiding the phenomenon of insufficient warning effect in the dim places in the subway station, so as to ensure the quality of operation and maintenance in the subway station.

With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a new type of safety device for subway operation is provided.

[0026] Now, in combination with the drawings and specific implementation manners, the present invention is further described as follows. For example, Figures 1 - 5As shown in the figure, a new safety device for subway operation according to an embodiment of the present utility model includes two symmetrically arranged support columns 1. A cavity 2 is provided inside the support column 1. A threaded column 3 is inserted through the bottom of the cavity 2. A base 4 is provided at the bottom end of the threaded column 3. An adjusting knob 5 is sleeved on the outer circumference of the bottom of the threaded column 3. A plurality of equally spaced folding components 6 are arranged between the two support columns 1, and a protection column 7 is arranged between two adjacent folding components 6.

[0027] With the above technical solution, through the support column 1 with an internal cavity 2, the height adjustment of the overall structure can be realized by the action of the threaded column 3 and the adjusting knob 5, so as to meet more and more complex usage scenarios. Moreover, the adjustment is convenient and fast, the operation is simple, which can effectively save the workload and operation difficulty of the user, and improve the operation and maintenance protection effect.

[0028] In one embodiment, for the above support column 1, a warning light 8 is provided at the top end of the support column 1, and connection buckles 9 are provided at both the bottom and the top of the outer side of the support column 1, so as to improve the warning effect. By using the connection buckles 9, the connection of multiple operation protection devices can be realized, and then the maintenance isolation of locations with a large range or distance can be carried out.

[0029] In one embodiment, for the above threaded column 3, a limit column 10 is provided at the top end of the threaded column 3. Both the cavity 2 and the limit column 10 are cylindrical structures and have the same diameter. The diameter of the threaded column 3 is smaller than the diameter of the limit column 10, so as to ensure the stability of the support column 1 and prevent it from tilting and shaking on the outer side of the threaded column 3.

[0030] In one embodiment, for the above-mentioned support column 1, an upper fixing seat 11 is arranged at the top inside the support column 1, and a lower fixing seat 12 is arranged at the bottom inside the support column 1. The folding assembly 6 includes a first upper connecting rod 601, a second upper connecting rod 602, a first lower connecting rod 603 and a second lower connecting rod 604. The first upper connecting rod 601 and the second upper connecting rod 602 are movably connected to each other, and the first lower connecting rod 603 and the second lower connecting rod 604 are movably connected to each other. A vertical connecting rod 605 is arranged between the intersection point of the first upper connecting rod 601 and the second upper connecting rod 602 and the intersection point of the first lower connecting rod 603 and the second lower connecting rod 604. The two upper fixing seats 11 are respectively movably connected to the first upper connecting rod 601 and the second upper connecting rod 602, and the two lower fixing seats 12 are respectively movably connected to the first lower connecting rod 603 and the second lower connecting rod 604. The protection column 7 is a U-shaped hollow structure. The inner top of the protection column 7 is respectively movably connected to the first upper connecting rod 601 and the second upper connecting rod 602, and the inner bottom of the protection column 7 is respectively movably connected to the first lower connecting rod 603 and the second lower connecting rod 604, so as to realize the connection between the two support columns 1 and the multiple protection columns 7. By using the folding function of the upper and lower groups of connecting rods in the folding assembly 6, the storage and deployment of the protection device are realized, and the upper and lower groups of connecting rods can ensure the protection range and area.

[0031] Multiple folding assemblies 6 are arranged and connected in sequence. The protection column 7 plays a connecting role. The first upper connecting rod 601, the second upper connecting rod 602, the first lower connecting rod 603 and the second lower connecting rod 604 are all J-shaped structures, and the intersection points thereof are arc-shaped to prevent the two connecting rods from jamming in the folded state. The folding assemblies 6 on the outermost sides play the role of connecting the support column 1 and the protection column 7, and the remaining intermediate folding assemblies 6 play the role of connecting the respective protection columns 7. Each folding assembly 6 forms two parallelograms, and the telescopic folding of the protection device is realized by using the deformable characteristics of the parallelogram.

[0032] In one embodiment, for the above-mentioned protection column 7, reflective warning strips 13 are arranged on both the front and the back of the protection column 7, so as to improve the warning effect of the protection device.

[0033] In order to facilitate the understanding of the above technical solution of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0034] During actual application, the staff carry the operation protection device in the folded state to the working area in the subway station. First, the device can be placed horizontally on the ground and adjusted according to the required height of the scenario. Specifically, rotate the adjustment knob 5, and draw the threaded column 3 to slide in the cavity 2 until the height meets the usage requirements. Then, adjust the adjustment knob 5 to a suitable position. Finally, as the support column 1 stands upright, the support column 1 is pressed against the adjustment knob 5 under the action of gravity. After determining the height, two staff members respectively drag the two support columns 1 to move to both sides, so that the folding assembly 6 is completed and unfolded, and finally forms a protective fence after being fully unfolded to prevent people from accidentally entering the working area and getting into danger.

[0035] This operation protection device is preferably applicable to the operation protection of subways and plays a protective role when maintaining the facilities and equipment in the subway station. By using warning lights and reflective strips, it can achieve the purpose of warning and reminding in relatively dim scenarios. However, this device is also applicable to working scenarios similar to subway stations, such as road construction, construction sites and other scenarios that require isolation and protection.

[0036] In summary, by means of the above technical solution of the present utility model, through the support column 1 with an internal cavity 2, the height adjustment of the overall structure can be realized by the action of the threaded column 3 and the adjustment knob 5, which is convenient for carrying and transferring in the subway station and placing in various places, so as to meet more and more complex usage scenarios. Moreover, the adjustment is convenient and fast, the operation is simple, which can effectively save the workload and operation difficulty of the users and improve the operation and maintenance protection effect. By setting the foldable and retractable folding assembly 6 and the protection column 7, the state switching between the folding and storage and the unfolding and protection of the protection device can be realized, effectively improving the portability and flexibility of the protection device, and having a strong protection ability in the unfolded state, that is, using multiple protection columns 7 and reflective warning strips 13 to achieve the functional purpose of warning and protection, avoiding the phenomenon of insufficient warning effect in the dim places in the subway station and ensuring the quality of operation and maintenance in the subway station.
