Description
Technical field
The utility model belongs to the electric power apparatus examination technical field of tools, relates in particular to a kind of anti-fall support that uses in electric power apparatus examination work.
Background technology
In substation equipment service work process, the substation equipment maintenance and repair personnel in the overhead rheology more than two meters high, press when need of work is walked about work on the stands such as change, lightning arrester, plug-in strip, the safety belt of being worn does not often have reliable system.When the substation equipment maintenance and repair personnel stand in when working on the channel-section steel, normally safety belt is tied up on the channel-section steel, the mode of the high usefulness of this low extension is very dangerous, and this moment, staff if fall on stand fell, and the personnel that very easily cause injure.Perhaps, the substation equipment maintenance and repair personnel tie up to safety belt and carry out work on the porcelain insulator, and this moment, the gravity of health was all born by porcelain insulator, was easy to porcelain insulator is fractureed, thereby had potential safety hazard.
The utility model content
The technical problems to be solved in the utility model provide a kind ofly be convenient to install, safe and reliable anti-fall support.
The utility model comprises a support bar, the fixedly connected safety belt binding ring on the top of described support bar; The bottom of described support bar connects a backup plate, and backup plate is vertical layout, and the top of described backup plate one side is connected on the lower external face of support bar; Connect two or more gib headed bolts on the remainder of backup plate, the front end of described each gib headed bolt is provided with a gib head, and backup plate is run through in the rear end, and the handwheel that is threaded in the rear end of each gib headed bolt.
As improvement of the present utility model, bilateral symmetry ground at support bar connects two anti-inclination stiffeners, the medial shaft of each anti-inclination stiffener is connected on the lateral surface of support bar to side, the lower side of each anti-inclination stiffener and the downside of support bar are substantially flush, each anti-inclination stiffener and backup plate almost parallel.
As improvement of the present utility model, connect a stiffener respectively, stiffener and backup plate approximate vertical at two vertical sides of backup plate.
As improvement of the present utility model, several gib headed bolts are set on backup plate run through through hole.
As improvement of the present utility model, support bar is an expansion link, and it is made up of outer tube and interior bar, and interior bar places outer tube.
Improve again as of the present utility model, several vertical upper shed grooves of arranging are set on the tube wall of the top of outer tube, the shroud ring spare of between the peripheral shroud ring one of the outer tube of the upper shed groove that is provided with vertical layout can be with outer tube and interior bar, locking, described shroud ring spare integral body is cylindric, vertical direction along shroud ring spare is provided with a breach on shroud ring spare, the two vertical sides of forming the shroud ring spare of above-mentioned breach stretch out and form the pair of bolts connecting plate, and a bolt locking member is connected can be with banding between outer tube and the interior bar on the above-mentioned pair of bolts connecting plate.
As further improvement of the utility model, the upper surface of shroud ring spare extends internally and forms all inward flanges.
The utility model is easy for installation, and before carrying out the substation equipment service work, the gib head with gib headed bolt is stuck on the channel-section steel earlier, and will lock between gib headed bolt and the channel-section steel by rotating handwheel, thereby whole anti-fall support vertically is locked on the channel-section steel.The utility model is safe and reliable, and when the substation equipment maintenance and repair personnel stand in when working on the channel-section steel, safety belt ties up on the safety belt binding ring that is in supporting bar top, thereby has avoided in the prior art safety belt tied up to the potential safety hazard that exists on channel-section steel or the porcelain insulator.
When anti-fall support vertically is locked on the channel-section steel, the lower side of two anti-inclination stiffeners and the lower surface of support bar are against on the upper side of channel-section steel in the lump, thereby increased the contact-making surface of anti-fall support and channel-section steel, guaranteed that anti-fall support more firmly is locked on the channel-section steel, prevented the stressed back run-off the straight in anti-fall support upper end in service work.
Stiffener then is in order to strengthen the anti-bending strength of backup plate.
Because several gib headed bolts are set on backup plate runs through through hole, so the distance between the gib headed bolt can be adjusted, to adapt to anti-fall support is connected on the channel-section steel of different model.
Telescopic support bar can be regulated the height of safety belt binding ring, thereby adapts to the substation equipment maintenance and repair personnel of different heights.
Because several vertical upper shed grooves of arranging are set on the top tube wall of outer tube, so deformation easily takes place in the top of outer tube when shroud ring spare hoop tightens up by bolt, thus can be with banding between sleeve pipe and the interior bar.
The upper surface of the shroud ring spare all inward flanges that form that extend internally can be against on the upper surface of outer tube, glide along outer tube to stop shroud ring spare.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is that A among Fig. 1 is to structural representation.
Embodiment
As depicted in figs. 1 and 2, anti-fall support comprises a support bar 1, and a fixedly connected safety is treated binding ring 2 on the top of described support bar 1.
The bottom of described support bar 1 connects a backup plate 3, and described backup plate 3 is vertical layout, and the top in backup plate 3 fronts is connected on the lower external face of support bar 1, connects two gib headed bolts 4 on the remainder of backup plate 3.The front end of each gib headed bolt 4 is provided with a gib head 4-1, and backup plate 3 is run through in the rear end, and the handwheel 4-2 that is threaded in the rear end of each gib headed bolt 4.Going to upper and lower direction between two gib headed bolts 4 arranges, and several gib headed bolts are set on the backup plate between two gib headed bolts 43 run through through hole 3-1, thereby so that regulate the channel-section steel that two distances between the gib headed bolt 4 are connected anti-fall support different model.
On two vertical sides of backup plate 3, connect a stiffener 5 respectively, described two stiffeners 5 and backup plate 3 approximate vertical, and two stiffeners 5 are in the back side one side of backup plate 3.
In addition, bilateral symmetry ground at support bar 1 connects two anti-inclination stiffeners 6, the medial shaft of each anti-inclination stiffener 6 is connected on the lateral surface of support bar 1 to side, simultaneously, the downside of the lower side of two anti-inclination stiffeners 6 and support bar 1 is substantially flush, and two anti-inclination stiffeners and backup plate 3 almost parallels.
As depicted in figs. 1 and 2, the gib head 4-1 of two gib headed bolts 4 blocks the upper and lower side of channel-section steel 8 respectively, rotates handwheel 4-2 with locking between gib headed bolt 4 and the channel-section steel 8, thereby whole anti-fall support vertically is locked on the channel-section steel 8.
