Description
Technical Field
The invention belongs to the technical field of guardrail rods, and particularly relates to a guardrail rod for overhauling power equipment.
Background
Guardrail bars are referred to herein as industrial "guardrail bars". The guardrail is mainly used for protecting and protecting personal safety and equipment facilities in occasions such as houses, roads, commercial districts, public places and the like. The guard rail is visible everywhere in our lives. The price per meter length of the guardrail can also be different according to the height. The guardrail of different grade type undertakes different protection tasks, need use guardrail bar when power equipment overhauls at present, need enclose the operation scene and separate, enclose and separate the guardrail and do not establish the part often, in the post hole on time-consuming cartridge ground, demolish when not, it is convenient to require the loading and unloading, and the cartridge is firm. The existing guardrail column is a section of round steel pipe with the length of about one meter, the lower end of the round steel pipe is not processed, and the round steel pipe is inserted into a pit dug on site in an original state in a floating mode to form a gravity pair matching mode. Although the loading and unloading are convenient, the loading and unloading are not firm enough, and the guardrail rod can be pulled out accidentally, and the introduction of the guardrail rod for overhauling the electrical equipment can be seen in the journal period: the collision simulation analysis of the treegand army, the Lisa thinking, the cinnabar, the Lixia, the SAm-level anti-collision movable guardrail is a system simulation study, 2020(03), however, the current protective guardrail rod for the electric power equipment maintenance still has certain problems, and the method specifically comprises the following aspects:
be used for rural or outdoor guardrail bar structure more singlely specially among the prior art, when comparatively leveling open air on ground overhauls equipment, only utilize the supporting shoe of guardrail bar bottom to support, thereby take place to incline easily and empty, thereby play not playing the effect of warning passerby, when comparatively inclining open air on ground overhauls equipment, bury guardrail bar in the soil usually and prevent that guardrail bar from taking place to empty, thereby increase maintainer's work efficiency's problem.
There are also some proposals related to guardrail bar for power equipment maintenance in the prior art, such as patent numbers: 201611223537.X, the patent name is a guardrail bar for electrical equipment overhaul, and this technical scheme is through setting up pole base and the body of rod, dare in through inserting the body of rod, fixed through the gear intermeshing in the body of rod, but this technical scheme's weight is heavier, is unfavorable for carrying for a long time, only utilizes the gravity of pole base to accomplish to prevent that the guardrail bar from taking place to topple over simultaneously.
In view of this, in order to overcome the above technical problems, the present applicant has designed and developed a guardrail bar for electrical equipment maintenance, and manufactured a special guardrail bar, so as to solve the above technical problems.
Disclosure of Invention
In order to make up for the defects of the prior art, the guardrail rod for electric power equipment maintenance is mainly used for solving the problems that in the prior art, the guardrail rod specially used in rural areas or outdoors has a single structure, when equipment is maintained outdoors with a flat ground, the guardrail rod is supported only by the supporting block at the bottom of the guardrail rod, so that the guardrail rod is easy to tilt and tilt, the function of warning passersby cannot be realized, when the equipment is maintained outdoors with a tilted ground, the guardrail rod is usually buried in the soil to prevent the guardrail rod from tilting, and the working efficiency of maintenance personnel is increased.

As an embodiment of the present invention, the outer surface of the first long rod 16 is fixedly connected with an arc-shaped strip 193 at the conical surface of the first long rod 16;
during operation, owing to be equipped with arc 193 on the 16 conical surfaces of first stock, can improve the land fertility of grabbing of first stock 16 at the in-process of first stock 16 to the soil internal rotation, make in the comparatively easy soil that inserts of first stock 16, can further improve guardrail bar's firm degree at this in-process, prevent that guardrail bar from taking place to empty.
As an embodiment of the present invention, a third sliding slot 161 is opened in the inner wall of the first rail 1 above each square groove 131, and a support rod 171 is slidably connected in each third sliding slot 161;
the during operation, because be equipped with bracing piece 171 in the first railing 1, when guardrail bar is under construction on comparatively level and smooth ground, can take bracing piece 171 in the third spout 161 out, after bracing piece 171 is taken out, can improve the support degree to guardrail bar, can also remind pedestrian and the vehicle of passing by simultaneously, prevent that pedestrian and vehicle are close to and influence the staff construction.
The specific working process is as follows:
when the guardrail is used outdoors, the controller is firstly used for controlling the drive shaft of the motor 12 to stretch until the drive shaft is meshed with the third gear set 15, and simultaneously controlling the motor 12 to rotate, in the rotating process of the motor 12, the first gear 13 is meshed with the second gear 14 and the third gear set 15, so that the second gear 14 can be driven to rotate and the third gear set 15 can be driven to rotate, in the rotating process of the second gear 14, the lead screw 21 can be driven to rotate, and the lead screw 21 is connected with the second guardrail 2 through the thread rotation, so that the second guardrail 2 can be driven to move upwards, in the process, the height of the guardrail can be increased, so that the guardrail is more striking, in the rotating process of the first gear 13 driving the third gear set 15, because the third gear set 15 is meshed with the first gear teeth 17, so that the first long rod 16 can be driven to rotate, and because the first long rod 16 is connected with the circular plate 194 through the thread, the circular plate 194 can drive the first circular rod to move downwards in the rotating process of the first long rod 16, and the first gear teeth 17 are designed in a spiral manner, so that the first long rod 16 can be prevented from being incapable of being driven to rotate in the rotating process of the third gear set 15, after the control rod 18 arranged in the first long rod 16 is matched with the clamping groove 195 arranged in the circular plate 194, the circular plate 194 can be driven to move downwards, the lower surface of the circular plate 194 is fixedly connected with the spiral rod 196, so that the spiral rod 196 can be screwed into soil, the fixing degree of the guardrail rod and the ground can be increased in the process, the guardrail rod is prevented from falling down to reduce the warning effect on pedestrians, meanwhile, the guardrail rod can be suitable for uneven ground and inclined ground, meanwhile, stronger ground holding force can be provided for the first long rod 16, the first long rod 16 is inserted into the ground, and the fixing degree of the guardrail rod can be further improved, when the circular plate 194 moves to the lower side of the elongated slot 11, the controller controls the control rod 18 to contract inwards, and the first long rod 16 is driven by the third gear set 15 to continue moving downwards, so that the grip of the guardrail bar can be further improved, the guardrail bar is prevented from being inclined, and the warning effect of the guardrail bar is reduced.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
