Embodiment 1

[0025] figure 1 It is a schematic diagram of an anti-electromagnetic interference telescopic boom provided according to an embodiment of the present invention, and the telescopic boom is applied to a crane. Such as figure 1 As shown, the telescopic boom includes: a first anti-interference module 10, a second anti-interference module 20 and a cable reel 30, wherein the first anti-interference module 10, the second anti-interference module 20 and the cable reel 30 are all provided On the telescopic boom of the crane, the first anti-interference module 10 is connected to the first end of the cable reel 30 , and the second anti-interference module 20 is connected to the second end of the cable reel 30 .

[0026] Specifically, the cable reel 30 is used to transmit control signals and power signals for the control system of the telescopic boom. For example, the cable reel 30 can be connected to the control system and electrical components of the telescopic boom, and the electrical...

Embodiment 2

[0049] Figure 5 It is a schematic diagram of the third anti-electromagnetic interference telescopic boom provided according to an embodiment of the present invention, as shown in Figure 5 As shown, the telescopic boom includes: a first interference eliminator 51 , an in-arm cable reel 52 and a second interference eliminator 53 .

[0050] The first interference eliminator 51 is arranged between the I / O module of the telescopic boom and the cable reel 52 in the arm, and is used for bus, power line and digital signal line between the I / O module and the cable reel in the arm. And the electrical signal in the analog signal line is filtered and processed. Wherein, the I / O module is the I / O module of the sensor of the telescopic boom.

[0051] The second interference eliminator 53 is arranged between the arm tail junction box and the cable reel in the arm of the telescopic boom, and is used for bus, power line, digital signal line and The electric signal in the analog signal lin...

Abstract

The invention discloses an anti-electromagnetic interference telescopic boom and a crane. The anti-electromagnetic interference telescopic boom comprises a first anti-interference module, a second anti-interference module and a cable drum, wherein the first anti-interference module, the second anti-interference module and the cable drum are arranged on the telescopic boom of the crane, the first anti-interference module is connected with the first end of the cable drum, and the second anti-interference module is connected with the second end of the cable drum, the cable drum is used for transmitting a control signal and a power signal for a control system of the telescopic boom, the first anti-interference module is used for performing filtering processing and encryption operation on the control signal, and the second anti-interference module is used for performing re-filtering processing, decryption operation and signal amplification operation on the control signal. The anti-electromagnetic interference telescopic boom and the crane alleviate the technical problem that electromagnetic interference signals cannot be effectively shielded in the prior art.

Description

technical field [0001] The invention relates to the technical field of anti-electromagnetic interference, in particular to an anti-electromagnetic interference telescopic boom and a crane. Background technique [0002] With the process of modern industrialization, more and more large-volume, heavy-weight components and devices require cranes for installation, disassembly, and transfer. Truck cranes are more and more used in various occasions due to their small footprint, flexible transition, and fast construction speed. [0003] Due to its special structure, the horizontal bar bolt barrel jib crane is the optimal technical direction for large-tonnage truck cranes and super-large-tonnage truck cranes. A core element of the horizontal bar bolt barrel arm is the control system of the horizontal bar bolt mechanism in the barrel arm. Since the control system needs to move back and forth repeatedly with the telescopic cylinder barrel, at least one cable that can be passively pull...
