Description

Technical Field

[0001] This utility model relates to the field of safety corridors, and in particular to a safety protection corridor for construction machinery in high-speed railways under ultra-high voltage lines. Background Technology

[0002] In recent years, with the rapid development of high-speed railways, high-speed rail lines inevitably intersect with high-voltage power transmission lines. Especially when intersecting with ultra-high-voltage power transmission lines, the distance between high-speed rail construction machinery and high-voltage lines must be strictly maintained within a safe distance range; otherwise, electric shock accidents can easily occur.

[0003] To prevent such accidents, the "Detailed Rules for the Implementation of the Regulations on the Protection of Power Facilities of the People's Republic of China" stipulates that safety measures must be taken during construction. Currently, this is mainly achieved by constructing protective corridors. Existing protective corridors are all fixed in a certain location. If the construction distance is long, some choose to build a protective corridor of the same length; others choose to build a section, dismantle it after completion, and then rebuild it along the construction direction. The former wastes more materials and is more costly; the latter is more troublesome and time-consuming, seriously affecting construction efficiency. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a safety protection corridor for construction machinery in high-speed railways under ultra-high voltage lines. By transferring two sections of the corridor together, it extends in the direction of construction, which not only has the advantage of low cost, but also enables continuous construction and has high construction efficiency.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A construction safety protection corridor for high-speed railway construction machinery under ultra-high voltage lines includes foundation components, guide components, and protective components;

[0007] The foundation component consists of two parallel foundation components. Each foundation component includes multiple foundation blocks spaced apart along the construction direction. Each foundation block has a first positioning hole on its top.

[0008] The guide component consists of two rows of guide components that cooperate with the base component. Each row of guide components includes two sets of guide rails arranged in sequence. Each set of guide rails overlaps at least two base blocks. Each set of guide rails has an inner guide groove and an outer guide groove at the top. The inner guide groove and / or the outer guide groove has a second positioning hole on the side that can cooperate with the first positioning hole, so that the guide rail can be positioned and connected to the base block via the first connector.

[0009] The protective components include an inner protective pergola and an outer protective pergola. The bottom of the inner and outer protective pergolas are respectively provided with moving wheels. The moving wheels of the outer protective pergola cooperate with the outer guide groove, and the moving wheels of the inner protective pergola cooperate with the inner guide groove, so that the outer and inner protective pergolas can be fitted and moved. The outer and inner protective pergolas are respectively provided with a plurality of third positioning holes. The guide rail is provided with a fourth positioning hole that can cooperate with the third positioning holes, so that the outer and inner protective pergolas can be positioned and connected to the guide rail via a second connecting member.

[0010] Furthermore, the first connector adopts a first limiting rod, which is connected to the first positioning hole, and the guide rail falls onto the first limiting rod through the second positioning hole to be positioned and connected to the base block.

[0011] Furthermore, each base block has a first limiting rod connected to its top two sides, and each side of the guide rail has a connecting protrusion with a second positioning hole.

[0012] Furthermore, the outer protective corridor and the inner protective corridor are respectively provided with two sets of third positioning holes, so as to position the second limiting rod through the third positioning hole and the fourth positioning hole.

[0013] Furthermore, the outer protective corridor includes an n-shaped frame, with casters at the bottom and a wire rope net at the top. The structure of the inner protective corridor is the same as that of the outer protective corridor.

[0014] Furthermore, both the upper part of the inner protective corridor and the upper part of the outer protective corridor are equipped with infrared alarms.

[0015] Furthermore, auxiliary wheels are provided at the bottom of both ends of the guide rail.

[0016] The advantages of this utility model using the above-mentioned technical solution are: the construction safety protection corridor for high-speed railway construction machinery under the ultra-high voltage line, through the sequential cooperation of basic components, guiding components and protective components, can extend the length of the protection corridor by alternating between the inner and outer protection corridors in the construction direction without affecting the continuity of construction, which not only ensures construction efficiency, but also has a low construction cost.

[0024] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0025] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0026] like Figure 1-4 As shown in this embodiment, the construction safety protection corridor for high-speed railway construction machinery under the ultra-high voltage line includes a foundation component a, a guide component b, and a protective component c.

[0027] The basic component a consists of two parallel basic components a1. Each basic component a1 includes multiple basic blocks a11 spaced apart along the construction direction. Each basic block a11 has a first positioning hole on its top.

[0028] The guide component b consists of two rows of guide components b1 that cooperate with the base component a1. Each row of guide components b1 includes two sets of guide rails b11 arranged in sequence. Each set of guide rails b11 overlaps at least two base blocks a11. Each set of guide rails b11 has an inner guide groove b111 and an outer guide groove b112 at its top. The inner guide groove b111 and / or the outer guide groove b112 have a second positioning hole b113 on their sides that can cooperate with the first positioning hole, so that the guide rail b11 can be positioned and connected to the base block a11 via the first connector a12.

[0029] The protective component c includes an inner protective canopy c1 and an outer protective canopy c2. The bottom of the inner protective canopy c1 and the outer protective canopy c2 are respectively provided with moving wheels c21. The moving wheels of the outer protective canopy c2 cooperate with the outer guide groove b112, and the moving wheels of the inner protective canopy c1 cooperate with the inner guide groove b111, so that the outer protective canopy c2 and the inner protective canopy c1 can be fitted and moved. The outer protective canopy c2 and the inner protective canopy c1 are respectively provided with a plurality of third positioning holes c23. The guide rail b11 is provided with a fourth positioning hole b114 that can cooperate with the third positioning holes c12, so that the outer protective canopy c2 and the inner protective canopy c1 can be positioned and connected to the guide rail b11 via the second connecting member c3.

[0030] Furthermore, both the upper part of the inner protective corridor c1 and the upper part of the outer protective corridor c3 are equipped with infrared alarms c4. The infrared alarms can be commercially available devices, specifically comprising an infrared transmitter, an infrared receiver, an alarm, and a power supply. The infrared transmitter emits a fan-shaped infrared beam, and the emission wavelength can be set within a wide range. The infrared receiver is paired with the infrared transmitter and can receive reflected infrared light; the received wavelength should be the same as the emission wavelength of the paired infrared transmitter. The alarm is connected to the infrared receiver; when the infrared receiver receives a reflected infrared signal, the alarm activates and emits a warning sound, alerting construction personnel that machinery may be crossing the safety distance boundary. The power supply powers the infrared transmitter and receiver; each set of infrared transmitters and receivers is equipped with its own power supply, which has a power storage function to ensure the infrared alarm device functions normally during power outages.

[0031] Furthermore, the outer protective corridor c2 includes an n-shaped frame, with a moving wheel c21 at the bottom of the n-shaped frame and a wire rope net c22 at the top of the n-shaped frame. The structure of the inner protective corridor c1 is the same as that of the outer protective corridor.

[0032] The operating principle is as follows:

[0033] First, regarding the foundation components, the foundation blocks are made of poured concrete. After the foundation is poured, the surrounding soil is backfilled and compacted, so that most of the foundation is buried below the bottom surface to improve its resistance to overturning.

[0034] Next, fix two sets of guide rails onto the base block in sequence, naming them guide rail (1) and guide rail (2) from left to right. Then, install the inner protective corridor on guide rail (1) and fix it in position with the second connector. Install the outer protective corridor on guide rail (2) and fix it in position with the second connector.

[0035] After construction begins, when the work is transferred from under the inner protective corridor to under the outer protective corridor, the inner protective corridor is pulled to move along the inner guide groove from guide rail (1) to guide rail (2); then guide rail (1) is removed and transferred to the rear of guide rail (2) and fixed to the foundation block by the first connector; then the inner protective corridor is pulled to continue moving along the inner guide groove from guide rail (2) to guide rail (1) and fixed by the second connector. During the above transfer process, construction can be carried out continuously without interruption, ensuring high construction efficiency. When the work is transferred again from under the outer protective corridor to under the inner protective corridor behind it, the transfer of guide rail (2) and outer protective corridor can be carried out according to the above steps. In addition, the transfer of the outer and inner protective corridors can be achieved by pulling ropes from the front, which allows the transfer personnel to stay as far away from the construction site as possible, making it safer.

[0036] The protective principles of the inner and outer protective corridors are as follows: Infrared transmitters and receivers are installed 1 meter below the top of the steel pipes on both sides of the two protective corridors, according to the designed positions. The designed installation positions should ensure that there are no blind spots in the corridor. When construction machinery is raised and intrudes into the infrared emitting field, it will cause infrared light reflection, which will be received by the infrared receiver, thereby triggering the alarm to issue a warning, indicating that the construction machinery is at risk of crossing the safety distance boundary. In some cases, if the construction machinery is raised too quickly and cannot stop immediately after triggering the alarm, the steel wire rope net at the top of the corridor can act as a hard barrier, forcing the construction machinery to stop raising and preventing it from crossing the safety distance boundary, forming an induced current, and causing an electric shock accident.

[0037] In one specific embodiment, for ease of assembly and disassembly, the first connecting member can be configured as follows: Specifically, the first connecting member a12 adopts a first limiting rod, which is connected to a first positioning hole. The guide rail b11 falls onto the first limiting rod through a second positioning hole b113 to be positioned and connected to the base block a11. This structural configuration not only facilitates assembly and disassembly but also ensures the stability of the guide rail by increasing the length of the first limiting rod, preventing it from easily detaching from the first limiting rod.

[0038] Furthermore, each base block a11 has a first limiting rod connected to its top two sides, and the guide rail b11 has a connecting protrusion b115 on each side, with a second positioning hole on the connecting protrusion b115.

[0039] This setting is more stable

[0040] Furthermore, the outer protective canopy c2 and the inner protective canopy c1 are each provided with two sets of third positioning holes, which makes the temporary fixation between them and the guide rail relatively firm. Specifically, the second connecting piece can be a second limiting rod, which achieves positioning and fixation between the guide rail and the two protective canopies through direct insertion.

[0041] In one specific embodiment, in order to facilitate the transfer of the guide rail, auxiliary wheels b12 can be provided at the bottom of both ends of the guide rail b11.

[0042] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0043] Any aspects of this utility model not described in detail are known to those skilled in the art.
