Description

Pole hat

technical field

The utility model relates to a device for installing power transmission and distribution lines, in particular to a pole holding cap.

Background technique

Reinforced concrete poles are widely used on transmission and distribution lines. Assembling poles is one of the routine operations of power transmission and distribution companies in power supply companies. The workload is heavy, the technical requirements are high, the number of operators is large, and the risk is high. Due to the weight of the pole, which can reach several tons, and is a slender component, it is dangerous to install at high altitude, and it is very dangerous during the lifting process. Many tools are needed, and many parties need to work together during the operation, which is technically difficult and difficult to operate. The technical requirements are high. In the process of erecting the pole, if you use the inverted "herringbone" character pole to erect and release the pole, you must use the pole cap. The old-fashioned pole cap cannot separate the pole during the lifting process. Electric poles, making the pole erecting process incomplete.

Utility model content

The technical problem to be solved by the utility model is to provide a pole holding cap which can separate the pole holding and the electric pole during the pole erecting process.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a pole cap, which is characterized in that the two bases are connected by an upper fixing plate, and the upper end surface of the upper fixing plate is fixedly connected with two hook plates , the two hook plates are connected by a connecting column, the hook plate is provided with a duckbill-shaped opening, and an arc-shaped locking piece is arranged between the two hook plates at the duckbill-shaped opening, and the arc-shaped locking piece The middle part is hinged with the first connecting column below the duckbill-shaped opening, the left end of the arc-shaped locking part is connected with the second connecting column above the duckbill-shaped opening through a spring, and the arc-shaped locking piece The left end of the part is also provided with a card slot, and the left middle part between the two hook plates is fixedly connected with a locking mechanism, and the card slot is adapted to the locking mechanism.

The locking mechanism is composed of a fixed pipe, a spring bolt and a return spring, the fixed pipe is fixed between the two hook plates, the spring bolt is connected inside the fixed pipe, and the two spring bolts A return spring is arranged between the baffles, and the right end of the spring bolt fits into the slot.

A reinforcement is provided between the hook plate and the upper end surface of the upper fixing plate.

A mounting ring is fixedly connected to the lower end surface of the upper fixing plate.

The beneficial effect produced by adopting the above technical scheme is: When performing the pole erection operation, an "8"-shaped connection device is placed in the duckbill-shaped opening, and one end of the "8"-shaped connection device passes through the steel wire Connect the pole that needs to be erected, and the other end is connected to the power end through a steel wire. When the pole is erected to about 70°, the "8"-shaped connecting device will come out from the duckbill-shaped opening. At this time, the pole can fall off freely, and the electric pole is completed. The pole rises to complete the pole erection process. The mounting ring on the pole cap can be connected with a wire rope to prevent the pole from slipping suddenly and causing a safety accident. When the pole is put down, the "8"-shaped connecting device is stuck in the duckbill-shaped opening, and the arc-shaped locking part is closed to prevent the "8"-shaped connecting device from coming out of the duckbill-shaped opening, causing a safety accident .

Detailed ways

As shown in Figure 1, Figure 5 and Figure 6, a pole cap, two bases 1 are connected by an upper fixed plate 8, and the upper end surface of the upper fixed plate 8 is fixedly connected with two hook plates 2, the The two hook plates 2 are connected by a connecting column, the hook plate 2 is provided with a duckbill-shaped opening 4, and an arc-shaped locking part 5 is arranged between the two hook plates 2 at the duckbill-shaped opening 4. The middle part of the shaped locking part 5 is hinged with the first connecting column 13 below the duckbill opening 4, and the left end of the arc-shaped locking part 5 is connected to the second connecting column above the duckbill opening 4 through a spring 12. The connecting column 14 is connected, and the left end of the arc-shaped locking member 5 is also provided with a draw-in groove 6, and the middle part on the left side between the two hook plates 2 is fixedly connected with a locking mechanism 15, and the draw-in groove 6 and The locking mechanism 15 is adapted.

As shown in Fig. 3 and Fig. 4, described locking mechanism 15 is made up of fixing pipe 9, spring bolt 10 and return spring 11, and described fixing pipe 9 is fixed between described two hook plates 2, and described spring bolt 10 Connected to the inside of the fixed pipe 9 , a return spring 11 is provided between the two baffles of the spring bolt 10 , and the right end of the spring bolt 10 fits into the slot 6 .

As shown in FIG. 1 and FIG. 2 , a reinforcing member 7 is provided between the hook plate 2 and the upper end surface of the upper fixing plate 8 .

As shown in FIG. 3 , a mounting ring 3 is fixedly connected to the lower end surface of the upper fixing plate 8 .

When carrying out the pole erecting operation, at first the two bases 1 are set on the head of the holding pole and fixed. At this time, the arc-shaped locking part 5 does not close the duckbill-shaped opening 4 . Secondly, an "8"-shaped connection device is enclosed within the duckbill opening 4, one end of the "8"-shaped connection device is connected to the electric pole that needs to be erected by a steel wire, and the other end is connected to the power end by a steel wire. Connect the installation ring 3 on the pole cap with two steel wire ropes respectively, pull the steel wire rope at the power end, and when the pole stands up to about 70°, the "8"-shaped connecting device comes out from the duckbill-shaped opening 4, and simultaneously pulls the The two wire ropes that are connected with the installation ring 3 prevent the pole from slipping suddenly and cause a safety accident, and the pole is put down to the ground. Finally, tighten the steel wire at the power end of the "8"-shaped connection device to raise the pole to 90° to complete the erection of the pole.

When carrying out the pole down operation, firstly, the "8"-shaped connecting device is stuck in the duckbill-shaped opening 4, the spring bolt 10 is pulled outward, and the arc-shaped locking part 5 is lifted upward, and the spring bolt 10 is snapped into the The duckbill-shaped opening 4 is closed in the groove 6 of the arc-shaped locking part 5 to prevent the "8"-shaped connection device from coming out of the duckbill-shaped opening 4 and cause a safety accident. Then, operate the wire ropes at both ends of the "8"-shaped connection device and the wire ropes in the installation ring 3, and place the pole.
