DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0035] See also Figure 1-Figure 9 As shown, the utility model provides a rope-driven multi-purpose insulating telescopic arm, comprising a power assembly 1, a bottom fixed tube 2, a driving tube 3, a top telescopic tube 5 and a plurality of intermediate telescopic tubes 4, wherein the power assembly 1 is fixedly mounted at the bottom of the bottom fixed tube 2, the driving tube 3 is nestedly connected with the bottom fixed tube 2 and the driving tube 3 is connected with the power assembly 1.

[0036] The plurality of intermediate telescopic tubes 4 are respectively the first intermediate telescopic tube 4, the second intermediate telescopic tube 4, the third intermediate telescopic tube 4, ... the Nth intermediate telescopic tube 4. For example, the intermediate telescopic tubes 4 can be set to four, five, etc., and the diameters of these intermediate telescopic tubes 4 decrease from bottom to top, and they are nested and connected from bottom to top, and the uppermost intermediate telescopic tube 4 is nested and connected with the top telescopic tube 5. The driving tube 3 is driven by the power assembly 1, and the driving tube 3 can drive these telescopic tubes to rise or fall synchronously.

[0037] Reference Figure 8 and Fig. 9As shown, the present application scheme includes a tube body including a bottom fixed tube 2, a driving tube 3, a top telescopic tube 5 and a plurality of intermediate telescopic tubes 4, and an upper pull rope row 6 and a lower pull rope row 7 are arranged between any three adjacent tube bodies, and these three tube bodies are respectively called the lower section tube body, the intermediate section tube body and the upper section tube body from bottom to top (these three adjacent tube bodies may also be the bottom fixed tube 2, the driving tube 3 and the first intermediate telescopic tube 4), wherein one end of the upper pull rope row 6 is fixedly connected to the upper end of the lower section tube body, and the other end is fixedly connected to the lower end of the upper section tube body, and the upper pull rope row 6 passes through the upper end wire pulley 2g arranged at the upper end of the intermediate section tube body; one end of the lower pull rope row 7 is fixedly connected to the upper end of the lower section tube body, and the other end is fixedly connected to the lower end of the upper section tube body, and the lower pull rope row 7 passes through the lower end wire pulley 3e arranged at the lower end of the intermediate section tube body.

[0038] As one of the implementation methods of this case, for example Figure 8 and Fig. 9 , the bottom fixed tube 2 (called the lower tube body), the driving tube 3 (called the middle tube body) and the first intermediate telescopic tube 4 (called the upper tube body) are nested and connected in sequence, that is, the upper end of the upper pulley row 6 is fixedly connected to the first upper rope head fixing piece 2d installed on the bottom fixed tube 2, and then the upper pulley row 6 passes through the upper wire pulley 2g installed on the driving tube 3 and extends to the lower end of the first intermediate telescopic tube 4, and is fixedly connected to the first lower rope head fixing piece 3b installed at the lower end of the first intermediate telescopic tube 4. This structure is the connection structure of the upper pulley row 6, and the upper pulley row 6 can make each tube body rise synchronously; the specific principle of the rise is that when the driving tube 3 is subjected to the thrust of the power component 1, since the upper end of the upper pulley row 6 is connected and fixed to the upper end of the bottom fixed tube 2, the lower end of the first intermediate telescopic tube 4 will be subjected to the rising force, so that the first intermediate telescopic tube 4 can move upward, and the other intermediate telescopic tubes 4 are similar. Under the joint action of the upper pulley row 6, the remaining tube sections will make a synchronous rising movement to achieve the elongation of the telescopic tube (such as Figure 8As shown). For the pull-down rope row 7, the upper end of the pull-down rope row 7 is fixedly connected to the second upper end rope head fixing piece 2e installed on the bottom end fixed tube 2, and then the pull-down rope row 7 extends downward through the lower end wire pulley 3e installed at the lower end of the bottom end fixed tube 2 and is fixedly connected to the second lower end rope head fixing piece 3c set at the lower end of the first intermediate telescopic tube 4. This structure is the connection structure of the pull-down rope row 7, and the pull-down rope row 7 can make each tube body descend synchronously; the principle of descent is that when the driving tube 3 is subjected to the force applied by the power component 1, since the upper end of the pull-down rope row 7 is fixed to the upper end of the bottom end fixed tube 2, the first intermediate telescopic tube 4 will be subjected to the descending force and move downward, and then the remaining tube sections will perform synchronous descending movement under the joint action of each pull-down rope row 7, so as to shorten the telescopic tube. The connection method of the other three adjacent tube bodies through the upper pull rope row 6 and the lower pull rope row 7 is the same as the structure and principle in the example. When working, turn on the power, and the remote control controls the rise, fall or stop, so as to achieve the extension, shortening or stop of the telescopic arm.

[0039] The upper pull rope row 6 and the lower pull rope row 7 in the present application are both made of Kevlar tape, which has the characteristics of low density, high strength, good toughness, high temperature resistance and the like.

Among them, the power assembly 1 is a motor, and is preferably a servo motor. The servo motor is provided with an electromagnetic brake 1b, and the rear end of the housing of the servo motor is provided with a motor tail cover 1a with a snap-fit ​​threaded connection. The motor is connected to the bottom fixed tube 2 through a square tube base 12, and the output shaft of the motor passes through the square tube base 12 and is connected to one end of the ball screw 8. The servo motor can receive a control signal to achieve precise control of the motor. The snap-fit ​​threaded connection of the motor tail cover 1a is convenient for disassembly and has a certain degree of airtightness, which can well ensure the safe operation of the motor. The electromagnetic brake 1b can brake the ball screw 8 to stop the telescopic arm.

[0041] As a preferred embodiment of this case, refer to Figure 4 and Figure 5The bottom fixed tube 2, the driving tube 3, the top telescopic tube 5 and the plurality of intermediate telescopic tubes 4 all include an upper end seat assembly and a glass fiber reinforced plastic tube 2a, and the glass fiber reinforced plastic tube 2a has the advantages of being light, high-strength and insulating.

A magnet is also provided on the lower end connecting piece 3a of the driving tube 3, so that the magnet proximity switch 13 can capture the position of the telescopic tube.

[0043] Optionally, the first upper rope end fixing piece 2d, the second upper rope end fixing piece 2e, the first lower rope end fixing piece 3b and the second lower rope end fixing piece 3c all adopt a structure of fixing the rope ends with a buckle.

[0044] Furthermore, the screw nut 14 is mounted on the lower end connecting piece 3 a below the driving tube 3 , and the ball screw 8 passes through the lower end connecting pieces 3 a of a plurality of intermediate telescopic tubes 4 .

The rolling directions of the wire wheels and rollers are both axial. The upper end wire wheels 2g and the lower end wire wheels 3e are composed of deep groove ball bearings wrapped with bearing silicone sleeves, which can effectively reduce the friction force during the axial movement of the two sections of the pipe body, and at the same time reduce the radial runout tolerance to ensure the matching precision. The silicone sleeve can prevent the bearing from damaging the contact surface of the pipe. The outer side of the roller is also wrapped with a silicone sleeve. The lower end connecting member 3a has multiple lower end roller installation grooves 3a1 for installing the lower end roller 3d on both sides corresponding to the installation of the second lower end rope head fixing member 3c.
