Description

TECHNICAL FIELD

[0002] In civil construction, the complexity and variability of the construction environment often require the construction team to build corresponding protection devices according to the specific site conditions. In particular, in the environment of live-line construction, due to the long construction period and the limitation of power-off maintenance, the construction personnel can only carry out construction work under the live-line body or live-line system.

[0003] Although the height of the live-line system from the ground can meet the basic requirements of the construction personnel walking under it, the problems encountered during construction will be more complex, specifically including the following problems: (1) the tools used for construction may exceed the safe height due to improper operation or accidental situations, and even directly contact the live-line system above, resulting in the risk of electric shock; (2) a safety protection layer is built under the live-line system to separate the construction personnel from the live-line system above, but due to the long construction period, the live-line system is likely to malfunction due to its own reasons or construction reasons, at which time the protection layer will block the live-line system above, hindering the observation and maintenance of the live-line system, and the fault location and maintenance can only be carried out after the protection layer is removed, and the protection layer needs to be built again after maintenance, which is not ideal in terms of construction efficiency and real-time performance; (3) due to the high risk of live-line environment, isolation protection needs to be built around the construction area, and the isolation protection around generally has a structural connection with the protection layer above, when the protection layer above needs to be removed for maintenance, it will also affect the structural stability of the isolation protection around.

[0021] The charged interval safety protection equipment provided by the embodiment is characterized in that: the top support frame 20 is arranged, the top support frame 20 is used to mark the safe height and separate the charged system above from the construction area below to form an isolation protection layer; on this basis, the top support frame 20 is arranged in a pair, the turnover mechanism is arranged, a pair of turnover plates 101 are arranged at the bottom of the turnover mechanism, the two turnover plates 101 are fixedly connected with the two top support frames 20 respectively, the top support frame 20 can be converted between the horizontal state and the vertical state by using the turnover mechanism, when the top support frame 20 is in the horizontal state, the pair of top support frames 20 are located in the same plane and are tightly spliced on the inner side to ensure the protection effect, when the charged system above needs to be overhauled due to failure, the top support frame 20 is only needed to be converted to the vertical state by using the turnover mechanism, the two top support frames 20 can be separated from each other, the charged system above can be completely exposed to facilitate observation and overhaul, and the protection can be formed again by converting the top support frame 20 to the horizontal state by using the turnover mechanism again after the overhaul is completed, thereby effectively avoiding the problem that the protection layer affects the overhaul of the charged system; on this basis, the top support frame 20 is arranged in a rectangular frame shape, a plurality of base bars 21 are arranged on the top support frame 20, and a plurality of light shielding plates 30 are further arranged, the light shielding plates 30 are arranged in an array and are rotationally connected with the base bars 21, one column of light shielding plates 30 is arranged on each base bar 21, and two adjacent columns of light shielding plates 30 are arranged at intervals, so that the light of the light source above the light shielding plates 30 can pass through the interval between the two columns of light shielding plates 30 and reach the ground of the construction area, the elastic extension plates 31 are elastically connected on both sides of the light shielding plates 30, the magnets 32 are arranged on the extension plates 31, the extension plates 31 are elastically stretched by using the magnets 32 to attract each other, the interval between the two columns of light shielding plates 30 is shielded by using the extension plates 31, at this time, the light source above is completely blocked by the light shielding plates 30 and the extension plates 31, when the tool stretches upward and exceeds the safe height, the light shielding plates 30 or the extension plates 31 are pressed upward, the light shielding plates 30 are rotated under stress, the side of the light shielding plates 30 pressed is gradually tilted upward, until the magnetic force between the two magnets 32 exceeds the critical point, the two magnets 32 are separated, the extension plates 31 are elastically reset and withdrawn, the two extension plates 31 attracted to each other are separated from each other, a gap is formed between the two extension plates 31, at this time, the light source above instantaneously passes through the gap between the withdrawn extension plates 31 and reaches the ground of the construction area, and the construction personnel are timely prompted that the tool contacts the light shielding plates 30 above and exceeds the safe height; by the mutual combination of the above-mentioned features, the charged interval safety protection equipment can effectively solve the technical problems that the protection layer affects the overhaul of the charged system above and cannot timely warn that the tool exceeds the safe height when the construction is carried out in the charged environment above.

[0022] It should be noted that, in order to further facilitate identification, the light source above the light shielding plate 30 can adopt a colored light source, for example, a red light with a warning effect.

[0023] Please refer to Figure 6 andFigure 7 In order to further explain the specific structure of the extension plate 31 and the connection structure with the sunshade plate 30, an adjusting cavity 301 is formed in the sunshade plate 30, the adjusting cavity 301 penetrates through the opposite sides of the sunshade plate 30 along the length direction of the sunshade plate 30 to form an adjusting groove, and two extension plates 31 are respectively slidingly inserted into the two ends of the adjusting groove; a plurality of springs 33 are arranged in the adjusting cavity 301, and the two ends of the spring 33 are respectively connected with the inner sides of the two extension plates 31, when the spring 33 is in a natural state, the extension plate 31 is accommodated in the adjusting cavity 301.

[0024] By forming the adjusting cavity 301 in the sunshade plate 30 and making the adjusting cavity 301 penetrate through the sunshade plate 30 along the length direction to form the adjusting groove, the extension plate 31 is slidingly inserted into the adjusting groove, so that the extension plate 31 can be accommodated in the adjusting cavity 301; by arranging the spring 33, the end of the spring 33 is connected with the inner side of the extension plate 31, so that the extension plate 31 is elastically connected with the sunshade plate 30 through the spring 33; when the two adjacent extension plates 31 are attracted by the magnet 32, the spring 33 is elastically stretched and extends out of the adjusting cavity 301; when the two extension plates 31 are separated by overcoming the magnetic force limit of the magnet 32, the spring 33 is reset and retracted into the adjusting cavity 301 under the action of the elastic force of the spring 33.

[0025] It should be noted that the middle part of the spring 33 is preferably fixedly connected with the cavity wall of the adjusting cavity 30, so as to ensure that the spring 33 is always arranged in the middle.

[0026] In order to make the sunshade plate 30 automatically reset and further explain the rotating connection structure between the sunshade plate 30 and the base rod 21, a mounting hole is formed in the middle of the sunshade plate 30, and a mounting cylinder 34 is coaxially and rotatably connected with the mounting hole, the mounting cylinder 34 is arranged in the adjusting cavity 301, and the axial direction of the mounting cylinder 34 is parallel to the width direction of the sunshade plate 30; the inner diameter of the mounting cylinder 34 matches the diameter of the corresponding base rod 21, the sunshade plate 30 is arranged through the mounting hole and the mounting cylinder 34 and is rotatably connected with the corresponding base rod 21, a plurality of key grooves are formed in the inner wall of the mounting cylinder 34, and a plurality of key edges are correspondingly protruded on the side wall of the base rod 21; a torsional spring 35 is sleeved on the mounting cylinder 34, and the end of the torsional spring 35 is connected with the cavity wall of the adjusting cavity 301, when the torsional spring 35 is in a natural state, the sunshade plate 30 is arranged horizontally.

[0027] The base rod 21 is arranged in the mounting hole and the mounting cylinder 34 to achieve the rotational connection of the base rod 21 and the sun shield 30. Further, the key groove and the key edge are arranged to limit the rotation of the base rod 21 and the mounting cylinder 34, so that they can rotate together relative to the sun shield 30. Further, the torsion spring 35 is sleeved on the mounting cylinder 34, and the end of the torsion spring 35 is fixedly connected with the cavity wall of the adjusting cavity 301, so that the rotation of the mounting cylinder 34 is limited by the torsion spring 35 and the mounting cylinder 34 is reset to the horizontal state when it is not pressed by the tool.

[0028] Please refer to Figure 4 and Figure 5 In order to further facilitate the extension plate 31 to exceed the magnetic force critical point of the magnet 32, the outer end surface of the extension plate 31 is arranged as a cylindrical arc surface, and the generatrix is parallel to the width direction of the sun shield 30, so that the adjacent two extension plates 31 are in line contact when they are attracted to each other. The magnet 32 is embedded in the upper part of the outer end surface of the extension plate 31.

[0029] Through the above arrangement, on the one hand, due to the end surface of the cylindrical arc surface and the magnet 32 arranged on the upper part of the end surface of the extension plate 31, when the extension plate 31 is rotated to a certain angle, the two magnets 32 on the side of the extension plate 31 that is pushed upward by the tool will be directly physically separated, so that it is easier to overcome the magnetic force critical point of the magnet 32. On the other hand, the two magnets 32 of the downward inclined extension plate 31 on the other side are always in contact and attracted, so that the extension plate 31 is prevented from being retracted due to overcoming the critical point on the other side.

[0030] In order to further explain the specific structure of the top support frame 20 and the connection structure with the turnover plate 101, the top support frame 20 includes a pair of parallel arranged base beams 201 and a pair of parallel arranged support beams 202. The end of the support beam 202 is connected perpendicularly to the end of the base beam 201 to form a rectangular frame-shaped top support frame 20. When two top support frames 20 are arranged horizontally and coplanarly, the top parts of the pair of base beams 201 on the outer side are connected with the corresponding two turnover plates 101 respectively, so that the pair of base beams 201 on the inner side are arranged in parallel and closely.

[0031] Through the above arrangement, the middle part of the top support frame 20 forms a hollow rectangular area. By connecting the base beams 201 on the outer side with the turnover plates 101, the two base beams 201 on the inner side can abut against each other to ensure that the middle abutment part of the two top support frames 20 will not leak light.

[0032] It should be noted that the two base beams 201 on the inner side can be fixed by using existing quick fixing structures, such as pins, bolts, buckles, etc., for easy positioning, but they should be easily detachable for easy maintenance of the live system.

[0033] Please refer to Figure 10, in order to make further explanation to the connecting structure of the base bar 21 and the top support frame 20, the support beam 202 is slidingly connected with the base beam 201 located at the outer side, and is provided with a locking member; the top support frame 20 is provided with a folding frame, the folding frame comprises two groups of linearly arranged pairs of rotary arms 22, each pair of the rotary arms 22 is X-shaped and is hinged at the axis, and the hinge shaft is one of the base bars 21, two pairs of the rotary arms 22 arranged adjacently are hinged in a scissor type, the two groups of linearly arranged pairs of the rotary arms 22 are symmetrically arranged and are connected through all the base bars 21; the top of the base beam 201 is provided with an embedding groove 2011 matched with the base bar 21, the embedding groove 2011 extends along the length direction of the base beam 201, and both ends penetrate through the base beam 201; the outermost two base bars 21 of the folding frame are embedded in the two embedding grooves 2011 respectively, and both ends of the remaining base bars 21 are arranged on the top of the two support beams 202 respectively, the rotary arms 22 are arranged on the outer side of the corresponding support beam 202 through the base bar 21; the top of the base beam 201 is hinged with a plurality of buckles 2012, the free end of the buckle 2012 is detachably connected with the base beam 201, and when connected, the buckle 2012 can partially close the slot of the embedding groove 2011.

[0034] Through the above setting, the size of the top support frame 20 can be adjusted by the sliding connection of the support beam 202 and the base beam 201, so as to adapt to the range of different live working environments, the locking member is arranged to relatively fix the support beam 202 and the base beam 201 after adjustment; the folding frame is arranged in a scissor type structure assembled by the rotary arms 22, so that the folding frame can be folded and compressed, and can be adaptively adjusted according to the size of the top support frame 20, and is convenient to store when the live system is overhauled, so as to avoid affecting the overhaul; the embedding groove 2011 and the buckle 2012 are arranged, so that the folding frame can be detachably connected with the top support frame 20, which is convenient to assemble and disassemble, and the folding frame of the relatively adaptive size can be replaced according to the specific size of the top support frame 20, so as to ensure the distance between the adjacent base bars 21.

[0035] Please further refer to Figure 1 , on the basis of Figure 8 and Figure 9, in order to further explain the specific structure of the turnover mechanism, the turnover mechanism comprises two groups of longitudinal members and a pair of the turnover plates 101, and the two groups of longitudinal members correspond to the two turnover plates 101 respectively; the longitudinal member comprises a hanging seat 17, a driving plate 10 and an adjusting plate 11, the driving plate 10 and the adjusting plate 11 are arranged in parallel, and the plane where the driving plate 10 and the adjusting plate 11 are arranged is perpendicular to the length direction of the base beam 201; the top of the hanging seat 17 is connected with the external environment, and the driving plate 10 is pivotally connected to the lower part of the hanging seat 17; the driving plate 10 is pivotally connected with a tension rod 12 and a pull rod 13, and the three pivotally connected points of the driving plate 10 are arranged in a triangular shape; the free ends of the tension rod 12 and the pull rod 13 are pivotally connected with the adjusting plate 11 respectively; all the adjusting plates 11 included in each group of longitudinal members are vertically connected with the top surface of the corresponding turnover plate 101; the middle part of the tension rod 12 is vertically connected with an extension rod 14, one end of the extension rod 14 away from the tension rod 12 is pivotally connected with an auxiliary rod 15, and one end of the auxiliary rod 15 away from the extension rod 14 is pivotally connected with the bottom of the hanging seat 17; the upper part of the hanging seat 17 is pivotally connected with a hydraulic cylinder 16, the push rod of the hydraulic cylinder 16 is pivotally connected with the driving plate 10, and the hydraulic cylinder 16 can drive the driving plate 10 to rotate about the pivotally connected shaft of the hanging seat 17; when the driving plate 10 is rotated to a first angle, the corresponding top support frame 20 is arranged horizontally; when the driving plate 10 is rotated to a second angle, the corresponding top support frame 20 is arranged vertically.

[0036] Through the above arrangement, the hydraulic cylinder 16 drives the driving plate 10 to rotate between the first angle and the second angle, thereby driving the adjusting plate 11 to rotate by the driving plate 10, so as to drive the turnover plate 101 to switch between the horizontal state and the vertical state, and then drive the top support frame 20 to switch between the horizontal state and the vertical state. Since the tension rod 12 and the pull rod 13 form a quadrilateral rotating structure, the base beam 201 not only rotates in angle when rotating, but also moves in position, so that the base beam 201 rotated to the horizontal state is translated outward as much as possible to increase the overall size of the top support frame 20 and optimize the stress condition, and the base beam 201 rotated to the vertical state is retracted inward as much as possible to make the base beam 201 close to the side wall of the longitudinal member, so as to further retract the folding frame and the sliding structure of the support beam 202 and the base beam 201, thereby avoiding occupying too large volume and facilitating the operation of the live system maintenance.

[0037] It should be noted that the lengths of the tension rod 12, the pull rod 13, the extension rod 14 and the auxiliary rod 15 can be calculated and mathematically designed according to actual use requirements.
