[0002] Aerial work boom truck is a high-performance mechanical equipment, mainly used in some places of aerial work, such as construction, bridges, electricity, mining and other industries. It can quickly deliver construction personnel and equipment to the work position. It has the characteristics of high efficiency, simple operation, good safety, strong flexibility, etc., and is deeply favored by on-site construction personnel. At present, when on-site construction personnel rely on aerial work boom trucks to use electric tools for aerial work and need to take city power, the usual practice is to make a power cord on site at will, prefabricate a plug at one end, and directly insert it into the socket of the power supply point on the ground, and prefabricate the socket at the other end and directly put it into the work column of the aerial work boom truck for construction personnel working at high altitude to take power. The characteristics of this method are mainly reflected in: the power cord is not fixed in position and forms a flying line. It changes with the change of the position of the work column, causing interference and wear with other objects.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "inside", and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0028] The purpose of the utility model is to provide a safe power supply system for an aerial work boom vehicle, which can safely supply power by relying on the structural characteristics of the aerial work boom vehicle itself. To achieve the above purpose, the utility model provides the following technical solutions:

[0029] See also Figure 1 and Figure 2 The present embodiment provides a safe power supply system for an aerial work boom vehicle, comprising: an industrial plug 100 and a leakage protection switch 200 arranged on a turntable 01, the industrial plug 100 is connected to the input end of the leakage protection switch 200 through a first cable 300, the output end of the leakage protection switch 200 is connected to a platform socket 500 arranged on a working platform 02 through a second cable 400, the industrial plug 100 can be detachably connected to an industrial socket 600, the industrial socket 600 is connected to a wired plug 800 through a third cable 700, and the wired plug 800 is used to connect to a power supply; the second cable 400 is sequentially passed through the drag chain 03 and the inside of the flying arm.

[0030] Specifically, the industrial plug 100 and the industrial socket 600 mentioned in the present application are circuit connectors commonly used in industry, and are generally used in combination; the leakage protection switch 200 is also a common leakage protector, which can be used in a circuit to disconnect the power supply in time when leakage or short circuit occurs in the circuit, thereby reducing safety hazards; in the present embodiment, the industrial plug 100 and the leakage protection switch 200 will be installed on the turntable 01 of the aerial work arm vehicle for convenient power supply, and the two are connected through a first cable 300, which is led out from the terminal of the industrial plug 100 and connected to the incoming line end of the leakage protection switch 200; the platform socket 500 is an ordinary socket, and its specific type can be adjusted according to actual needs. The platform socket 500 is installed on the working platform 02 of the aerial work arm vehicle, which is convenient for construction personnel on the working platform 02 to obtain power, and the platform socket 500 is connected to the outgoing line end of the leakage protection switch 200 through a second cable 400.

[0031] It can be understood that the aerial work boom vehicle is generally a multi-section movable structure, and a drag chain 03 is provided along the direction of its telescopic arm to bind the cables or wires or hydraulic pipes to facilitate their rotation and movement. Therefore, in the present application, in order to prevent the second cable 400 from being directly exposed to the working environment, the second cable 400 is passed through the inside of the drag chain 03, and because the working platform 02 is connected to the flying arm of the aerial work boom vehicle, the flying arm is not provided with a drag chain 03. The second cable 400 extends from the drag chain 03 and is inserted into the inside of the flying arm until it passes through the working platform 02 and is connected to the platform socket 500. In this way, the second cable 400 will not move as the position of the working platform 02 changes when the aerial work boom vehicle is working, thereby preventing the second cable 400 from interfering with and wearing other objects, thereby improving the safety of power supply.

[0032] The industrial socket 600 and the wired plug 800 are connected through the third cable 700. The length of the third cable 700 can be selected according to actual needs. When power is needed, just plug the wired plug 800 into the power supply, and then connect the industrial socket 600 to the industrial plug 100 installed on the turntable 01. In this way, electricity can be safely transmitted to the platform socket 500 of the working platform 02. After the power is taken, the connection between the industrial plug 100 and the industrial socket 600 can be disconnected, and the industrial socket 600, the wired plug 800 and the third cable 700 can be stored.

[0033] That is to say, the industrial plug 100 and the leakage protection switch 200 are arranged on the turntable 01 of the aerial work boom vehicle, the industrial plug 100 is close to the leakage protection switch 200, and the two are connected by the first cable 300, and the platform socket 500 is installed on the working platform 02, so that the construction personnel can get electricity at the working platform 02, and the platform socket 500 is connected by the second cable 400; it should be noted that the arrangement of the second cable 400 is based on the structural characteristics of the aerial work boom vehicle, and is arranged inside the drag chain 03, which can be It moves back and forth with the drag chain 03, passes through the drag chain 03, and then passes through the inside of the flying arm connected to the working platform 02 again, until it is connected to the platform socket 500 set on the working platform 02; in order to facilitate power supply, a wired plug 800 and an industrial socket 600 are also provided, and the two are connected by a third cable 700, which can be used at any time. When power is needed, the wired plug 800 is connected to the power supply, and the industrial socket 600 is connected to the industrial plug 100, so that the platform socket 500 on the working platform 02 can be stably supplied with power. In this way, the cable used for power supply can be avoided from being exposed to the outside and changing with the position of the working platform 02, causing interference and wear with other objects. A leakage protection switch 200 is also provided, which greatly improves the safety when power is taken.

[0034] Preferably, a shielding member is provided above the turntable 01 where the industrial plug 100 and the leakage protection switch 200 are installed, and the shielding member is used to prevent rainwater from entering the industrial plug 100 and the leakage protection switch 200 .

[0035] It can be understood that in order to prevent rainwater from entering the industrial plug 100 and the leakage protection switch 200 when it rains, affecting their performance or causing safety accidents, a shielding member can be set on the turntable 01. The shielding member is located directly above the industrial plug 100 and the leakage protection switch 200, and its area can be adjusted according to actual conditions, as long as it can ensure that the industrial plug 100 and the leakage protection switch 200 can be protected.

[0036] Of course, if the industrial plug 100 and the leakage protection switch 200 are arranged too far apart on the turntable 01, shielding members can be respectively arranged above the industrial plug 100 and the leakage protection switch 200, and each shielding member only protects one part.

[0037] Preferably, the first electrical cable 300 is introduced into the incoming line terminal of the leakage protection switch 200 through a wire clamp.

[0038] It can be understood that the first cable 300 is used to connect the industrial plug 100 and the leakage protection switch 200. Both the industrial plug 100 and the leakage protection switch 200 are installed on the turntable 01. In order to prevent the first cable 300 from being in a flying wire state and being easily damaged by the working turntable 01, and to prevent the first cable 300 from tripping the operator, the first cable 300 is fixed to the turntable 01 through a wire clamp, so that it is introduced into the incoming line end of the leakage protector through the wire clamp; of course, the number of wire clamps is adjusted according to actual conditions.

[0039] Preferably, the leakage protection switch 200, the industrial plug 100 and the platform socket 500 are all provided with a waterproof box on the outside, and the waterproof box is provided with a movable protective cover for operating the leakage protection switch 200, the industrial plug 100 or the platform socket 500.

[0040] In this embodiment, in order to further waterproof the leakage protection switch 200, the industrial plug 100 and the platform socket 500, they can all be set in a waterproof box. Of course, in order to waterproof the leakage protection switch 200, the industrial plug 100 and the platform socket 500 without affecting their use, a movable protective cover can be provided on the outside of the waterproof box. The protective cover can be hinged on the box body. When the leakage protection switch 200, the industrial plug 100 and the platform socket 500 need to be operated or used, the movable cover is rotated. After use, the protective cover can be closed to strictly protect the parts inside the waterproof box.

[0041] Preferably, the second electrical cable 400 is introduced into the incoming end of the drag chain 03 through the first cable fixing device.

[0042] It can be understood that the part of the second cable 400 coming out from the outlet of the leakage protection switch 200 is fixed by the first wire fixing device and then enters the inlet of the drag chain 03. This arrangement is also to enable the second cable 400 to be fixed on the turntable 01, wherein the first wire fixing device can use a U-shaped clamp.

[0043] Preferably, the inlet and outlet ends of the drag chain 03 and the middle portion of the drag chain 03 are provided with a second wire fixing device for preventing the second electrical cable 400 from moving inside the drag chain 03 .

[0044] Furthermore, in order to prevent the second cable 400 from moving randomly in the drag chain 03, second cable fixing devices are provided at the cable input end, cable output end and the middle part of the drag chain 03. The second cable fixing devices provided at various parts inside the drag chain 03 cooperate with each other so that the second cable 400 is firmly fixed inside the drag chain 03. This can effectively prevent the wear of the second cable 400 and the drag chain 03, and can extend the service life of the second cable 400 and its safety during use.

[0045] Preferably, the inlet end, outlet end and middle part of the flying arm are provided with rubber protective covers to prevent the flying arm from causing wear to the second cable 400.

[0046] In this embodiment, the flying wall 04 is a structure at one end of the aerial work arm vehicle connected to the work platform 02. No drag chain 03 is set on the flying wall 04. Therefore, the second cable 400 will extend from the outlet end of the drag chain 03, and then enter from the inlet end of the flying arm, pass through the entire flying wall 04, and extend from its outlet end to connect to the platform socket 500. Similarly, in order to prevent the second cable 400 from moving freely in the flying wall 04 and causing wear, rubber protective covers are provided at the inlet end, outlet end and middle part of the flying arm, and the rubber protective covers also have a certain function of fixing the second cable 400.

[0047] It should be noted that, in the present embodiment, the length of the second cable 400 passing through the drag chain 03 and the flying wall 04 is greater than the total length of the drag chain 03 and the flying wall 04, that is, at the incoming and outgoing ends of the drag chain 03 and the incoming and outgoing ends of the flying arm, there is always a margin in the length of the second cable 400, so as to facilitate the pulling of the second cable 400 when the flying arm or the working platform 02 swings left and right.

[0048] Preferably, the portion of the second electrical cable 400 between the platform socket 500 and the flying arm is fixed by a third cable fixing device.

[0049] Specifically, the second cable 400 led out from the outlet end of the hollow structure of the flying arm is introduced into the platform socket 500 in the working platform 02 through the third wire fixing device. This arrangement is also to reduce the wear caused by the swing of the second cable 400 when the working platform 02 moves.

[0050] Preferably, the first cable 300 , the second cable 400 and the third cable 700 are specifically drag chain 03 cables.

[0051] In this embodiment, the first cable 300, the second cable 400 and the third cable 700 will inevitably wear out. In order to further enhance the service life of the first cable 300, the second cable 400 and the third cable 700, and to improve the safety of the cables when used, the three are preferably drag chain cables, which have better wear resistance.

[0052] Preferably, waterproof joints are provided at the joints of the first cable 300 , the second cable 400 and the third cable 700 .

[0053] In this embodiment, in order to enhance the waterproofness and safety of the power supply system, waterproof connectors are provided at the connections between the first cable 300, the second cable 400, the third cable 700 and each component, and the incoming and outgoing ends of the waterproof box are also provided with waterproof connectors.

[0054] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0055] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
