DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See Figure 1 The invention discloses an insulator cover clip electric mounting clamp, comprising an insulating tube 10, a clamping unit 20 at the upper end and a driving unit 30 at the lower end. The upper end of the insulating tube 10 is provided with a rectangular notch 12, and the lower end is glued with a rubber handle 11.

[0026] See Figure 2 The clamping unit 20 includes a fixed caliper portion 21 , a movable caliper portion 22 , a hinged pull rod 23 , an adapter 24 , three sets of pins 25 , an insulating connecting rod 26 , and a fastening sleeve 27 .

[0027] The bottom end of the fixed caliper part 21 is installed on the top end of the insulating tube 10, fixed by a fastening sleeve 27, and the middle part is a through hole. The movable caliper part 22 is S-shaped, and the middle part is inserted into the middle part of the fixed caliper part 21, and is assembled into a relatively rotatable pliers structure through a pin 25. The two clamping feet 28 at the head of the fixed caliper part 21 and the head of the movable caliper part 22 are the clamping working parts of the clamp.

[0028] See Figure 4 During operation, the clamping feet 28 are located on both sides of the front end boss of the buckle 41, and the head of the movable clamp part 22 pushes the rear end boss of the buckle 41 forward, and the front end boss of the buckle 41 passes through the socket 42 of the insulator cover to achieve the fastening installation of the buckle 41.

[0029] See Figure 3 The tightening thrust of the movable caliper part 22 is provided by the power of the rechargeable battery 33 of the driving unit 30. The electric operating device is a stepping electric push rod 31, and the head of the push rod 35 is a screw rod, which is connected to the insulating connecting rod 26 through a screw-connected threaded connector 34.

[0030] The push rod 35 , the threaded connector 34 , and the insulating connecting rod 26 are coaxially connected and installed in the insulating tube 10 .

[0031] By pressing the push-type reset switch 32 on the upper part of the rubber handle 11 , the electric power drives the motor inside the stepping electric push rod 31 to rotate, driving the push rod 35 to reciprocate, generating a forward thrust, which is synchronously transmitted by the insulating connecting rod 26 .

[0032] See Figure 2 The adapter 24 is connected to the upper part of the insulating connecting rod 26, and slides back and forth along the inner cavity of the insulating tube 10 under its action. The lower end of the articulated pull rod 23 passes through the notch 12 at the upper end of the insulating tube 10, and is connected to the adapter 24 in the tube through the pin 25 to form an axis-rotating structure; its upper end and the S-shaped lower end of the movable caliper part 22 form an axis-rotating structure through the pin 25.

[0033] The insulating connecting rod 26, the articulated pull rod 23 and the movable caliper part 22 form a planar connecting rod mechanism, which converts the linear reciprocating motion of the push rod 35 into the rotational motion of the movable caliper part, thereby realizing the clamping operation function.

[0034] See Figure 3 The lower end of the threaded connector 34 is screwed onto the right-handed thread of the push rod, and the upper end is screwed onto the left-handed thread of the insulating connecting rod; a number of sockets 36 are evenly distributed in the middle of the threaded connector 34, and a small annular hole is opened in the insulating tube 10, and the hole length covers two adjacent sockets 36. Use an ordinary screwdriver to insert into the socket 36, and the threaded connector 34 can be rotated to adjust the operating length of the stepping electric push rod.

[0035] See Figure 6, a block diagram of the principle of a control unit of an insulator cover clip electric mounting clamp.

[0036] The control unit is used to realize automatic clamping operation and control the operation rate.

[0037] The control unit includes a single chip microcomputer, a motor drive circuit, a power control module and a display module.

[0038] The single chip microcomputer is connected to the motor driving circuit of the stepping electric push rod 31 , and drives the motor to rotate and output torque, thereby driving the stepping electric push rod 31 to reciprocate.

[0039] The push-type reset switch 32 is connected to the single-chip microcomputer through a switch control circuit. When the push-type reset switch 32 is pressed once manually, the single-chip microcomputer controls the stepping electric push rod 31 to reciprocate once.

[0040] The single chip microcomputer is connected to the computer through the display module to set and update the operation parameters.

[0041] The MCU monitors the charge and discharge status of the battery through the charging control module and current sensor. The BMS can ensure that the battery operates within a safe range, warn of low power, and prevent overcharging and over-discharging, thereby avoiding thermal runaway of the battery and potential fire risks.

[0042] See Figure 4-Figure 5 , an operation method of an insulator cover buckle electric installation clamp, the installation process includes the following steps: (1) The adhesive portion 431 of the lifting ring 43 is glued to the truncated cone-shaped top of the insulator cover 40; (2) Insert the lifting portion 432 of the glued lifting ring into the hook ring 51 of the electric gun-type insulating operating rod 50, and control the electric operating mechanism 51 through the remote control to automatically close and tighten the hook ring 52; (3) Lift the insulating operating rod 53, put the insulator cover 40 into the insulator head at a high altitude, open the hook ring 52 by remote control, and remove the electric gun-type insulating operating rod 50; (4) According to the model and size of the insulator buckle, set the program data of the single-chip microcomputer and adjust the operating length and movement speed parameters of the stepper electric push rod; (5) Holding the rubber handle 11 at the bottom of the insulating tube 10, with the fixed clamp portion 21 and the movable clamp portion 22 of the clamping unit 20 in the open state, clamp the clamping unit 20 into the buckle 41 of the insulator cover 40; (6) The fixed caliper portion 21 is placed against the outer side of the insertion hole 42, with the two clamping feet 28 arranged on both sides of the insertion hole 42; (7) The finger clicks the push-type reset switch 32, and the stepping electric push rod 31 performs a reciprocating motion. Under the transmission action of the insulating connecting rod 26 and the hinged pull rod 23, the movable caliper part 22 and the fixed caliper part 21 perform a process of closing and opening. When closing, the head of the movable caliper part 22 pushes the buckle 41 of the insulator cover into the socket 42, thereby realizing the buckle 41 The installation operation is completed.

[0043] (8) Move the mounting clamp to the next socket 42 and repeat the above steps to complete the installation of the remaining clips 41 on the insulator cover.
