Offer fifth through-hole 24 and sixth through-hole 25 on inner tube 2, fifth through-hole 24 axial runs through inner tube 2, and be connected to the switch 5 who sets up on handle 4 on, square groove 26 is seted up to the bottom of inner tube 2, the size of square groove 26 is the same with chucking mechanism 3, chucking mechanism 3 is placed in square groove 26, set up sixth through-hole 25 between square groove 26 and inner tube 2 outer wall, the electric wire that switch 5 and electro-magnet 32 are connected can be placed in fifth through-hole 24 and sixth through-hole 25, fifth through-hole 24 and sixth through-hole 25 can also reduce the weight of inner tube 2, be favorable to saving operating personnel's physical power.
Referring to fig. 8, as a specific implementation of the embodiment of the present invention, the electromagnet 32 is adhered to the mounting plate 36 by a strong glue. Since the two electromagnets 32 are mounted at the same position on the mounting plate 36, they are not suitable for the fastener mounting method. The electromagnet 32 is bonded to the mounting plate 36 by the strong glue, so that the impact force generated by the electromagnet 32 and the magnet 34 in the process of attraction can be prevented from influencing the electromagnet 32, the fixed position of the electromagnet 32 is changed, and the attraction effect of the electromagnet 32 and the magnet 34 is further influenced.
In this embodiment, a mounting bracket may be provided on the mounting plate 36, the mounting bracket taking the form of a clamp that adjusts the clamping force via a bolt. The mounting bracket is used for placing the electromagnet 32, and the damaged electromagnet 32 can be conveniently replaced by using the mounting bracket in the form of the mounting bracket.
As a specific implementation manner of the embodiment of the present invention, please refer to fig. 5, a baffle ring 14 is disposed on the inner wall of the outer tube 1. The purpose of the stop ring 14 is to prevent the clamping mechanism 3 at the bottom of the inner tube 2 from colliding with the bottom of the outer tube 1 when the inner tube 2 is completely retracted into the outer tube 1. The height of the stop ring 14 inside the outer tube 1 from the bottom of the outer tube 1 should be greater than the height of the clamping mechanism 3.
In this embodiment, an elastic member may be further bonded to the retainer ring 14 for buffering the impact force generated when the inner tube 2 contacts the retainer ring 14. The elastic member may be selected from metals such as: an elastic washer; non-metallic materials, such as rubber pads, may also be selected.
As a specific implementation manner of the embodiment of the present invention, please refer to fig. 3, a handle 13 is disposed on the top of the outer tube 1. The top of outer tube 1 sets up handle 13, and handle 13 is the T type, makes things convenient for the operator to snatch. When the outer pipe 1 needs to be placed into the pre-buried pipe in the substation site, an operator can grasp the handle 13 to place the outer pipe 1 into the pre-buried pipe. The operator can also place the outer pipe 1 into the pre-buried pipe with the aid of a tool, the wall of the pre-buried pipe not interfering with the tool.
In this embodiment, a threaded hole can be formed in the top end of the outer tube 1, and the hanging ring is placed in the threaded hole. The hanging ring is used for replacing the handle 13, and the hanging ring has the advantage that when the pipe orifice of the embedded pipe is very low and the height of an operator is large, the operator can use a rope to penetrate through the hanging ring to place the outer pipe 1 into the embedded pipe.
The method of using the safety measure rod provided by the invention will now be described. The using method of the safety measure rod comprises the following steps:
a handle 4 for holding the top of the inner tube 2;
the inner tube 2 is lifted upwards while the switch 5 on the handle 4 is pressed;
after the inner tube 2 reaches a preset position, the switch 5 is released;
after the inner tube 2 does not slide any more, the handle 4 is released;
the safety warning belt is tied on the safety measure rod;
when the safety measure rod is not used, the safety warning belt is unfastened;
the switch 5 is pressed down, and the inner tube 2 is pressed down by holding the handle 4;
after the inner tube 2 is completely retracted into the outer tube 1, the switch 5 is released.
When the transformer substation needs to be maintained, an operator pulls out a safety measure rod in the pre-buried pipe, presses a button 5 of a switch on a handle 4, then pulls out the inner pipe 2 from the outer pipe 1 through the handle 4, and when the inner pipe 2 reaches a preset position, the button 5 of the switch is released, so that the switch 5 is reset, and the inner pipe 2 cannot slide in the outer pipe 1; then, a safety warning belt is tied on the safety measure rod, and the operation on the site can be finished. After the maintenance of transformer substation finishes, the operator will press the 5 on-switch buttons on the handle 4 once more to handheld handle 4 puts down inner tube 2, after inner tube 2 slided into outer tube 1 completely, loosens the button on the switch 5, makes switch 5 reset once more, can accomplish the receipts to the safety measure pole.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
