Description

Technical Field

[0001] This utility model relates to an automatic charging mechanism for the control device of the working platform of an insulated aerial work vehicle, belonging to the field of aerial work vehicles. Background Technology

[0002] According to the GB / T 9465 Aerial Work Platform Vehicle standard, the aerial work platform vehicle should be equipped with two sets of control devices, one upper and one lower. The upper control device should be located on the working platform. For insulated aerial work platforms, in order to meet the different voltage withstand performance requirements, it is not advisable to directly supply power to the control device on the working platform via cable.

[0003] Currently, most insulated aerial work platforms use either independent power supplies or hydraulic generators to power their upper control devices. However, both methods have distinct advantages and disadvantages: Independent power supplies offer the advantages of simple structure and low cost, but require frequent manual maintenance and charging after disassembly, resulting in poor user reviews; Hydraulic generators offer the advantage of continuous power supply without manual maintenance, but are complex in structure, heavy in weight, and expensive, and continuous power generation can lead to increased heating in the hydraulic circuits, reducing the efficiency of other operations. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and to provide an automatic charging mechanism for the working platform control device of an insulated aerial work vehicle with a reasonable structural design.

[0005] The technical solution adopted by this utility model to solve the above problems is: the automatic charging mechanism of the working platform control device of the insulated aerial work vehicle, characterized in that: it includes a fixed electrode assembly installed on a fixed working arm and a movable electrode assembly installed on a telescopic working arm, wherein the movable electrode assembly is in contact with the fixed electrode assembly; the fixed electrode assembly includes a fixed electrode support, a fixed electrode, and a fixed insulator, wherein the fixed electrode is installed on the fixed insulator, and the fixed insulator is installed on the fixed electrode support; the movable electrode assembly includes a movable electrode support, a movable insulator, and a movable electrode, wherein the movable electrode is installed on the movable insulator, and the movable insulator is installed on the movable electrode support, wherein the fixed electrode is in contact with the movable electrode.

[0006] Furthermore, the fixed electrode assembly also includes a connecting pin, a torsion spring, and a supporting pin. The connecting pin and the supporting pin are both mounted on the fixed electrode support. The torsion spring and the fixed insulator are both mounted on the connecting pin, with the torsion spring abutting against the fixed insulator and the fixed insulator contacting the supporting pin.

[0007] Furthermore, the fixed electrode assembly also includes a positioning bushing, an adjusting support, a positioning pin, and a second bolt. The positioning pin is fixed to the fixed electrode support, the positioning bushing is fitted over the positioning pin and mounted on the adjusting support, and the adjusting support is fixed to the fixed electrode support by the second bolt, which abuts against the positioning bushing.

[0008] Furthermore, the fixed electrode assembly also includes a connecting support and a first bolt, wherein the adjusting support and the connecting support are connected by the first bolt.

[0009] Furthermore, both the fixed electrode and the movable electrode are provided with wiring terminals.

[0010] Compared with the prior art, this utility model has the following advantages: When the insulated aerial work platform is in operation, the telescopic boom extends, the work platform control device is powered by an independent power supply, and the automatic charging mechanism is disconnected to ensure the insulated operation performance; when not in operation, the telescopic boom retracts, the work platform control device is powered off, and the automatic charging mechanism is turned on to charge the independent power supply of the work platform, eliminating the need for manual disassembly and carrying of the independent power supply into and out of the work platform.

[0011] The automatic charging mechanism of the work platform control device of this insulated aerial work platform solves the shortcomings of independent power supply, requires no manual maintenance, and can automatically charge the independent power supply on the work platform; at the same time, it has a cost advantage over hydraulic power generation.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0019] Example

[0020] See Figures 1 to 5 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0021] The automatic charging mechanism of the working platform control device of the insulated aerial work vehicle in this embodiment includes a fixed electrode assembly installed on the fixed working arm A and a movable electrode assembly installed on the telescopic working arm B, with the movable electrode assembly in contact with the fixed electrode assembly.

[0022] The fixed electrode assembly includes a connecting support 1, a fixed electrode support 2, a connecting pin 3, a torsion spring 4, a fixed electrode 5, a fixed insulator 10, a positioning bushing 11, an adjusting support 12, a first bolt 13, a positioning pin 14, a supporting pin 15, and a second bolt 16. The fixed electrode 5 is mounted on the fixed insulator 10, and the fixed insulator 10 is mounted on the fixed electrode support 2.

[0023] The movable electrode assembly includes a movable electrode support 7, a movable insulator 8, and a movable electrode 9. The movable electrode 9 is mounted on the movable insulator 8, and the movable insulator 8 is mounted on the movable electrode support 7. The fixed electrode 5 is in contact with the movable electrode 9. Both the fixed electrode 5 and the movable electrode 9 are provided with terminals 6.

[0024] Both the connecting pin 3 and the supporting pin 15 are mounted on the fixed electrode support 2. Both the torsion spring 4 and the fixed insulator 10 are mounted on the connecting pin 3, with the torsion spring 4 abutting against the fixed insulator 10 and the fixed insulator 10 contacting the supporting pin 15.

[0025] The positioning pin 14 is fixed to the fixed electrode support 2. The positioning sleeve 11 is fitted outside the positioning pin 14 and is installed on the adjusting support 12. The adjusting support 12 is fixed to the fixed electrode support 2 by the second bolt 16 and the second bolt 16 abuts against the positioning sleeve 11. The adjusting support 12 is connected to the connecting support 1 by the first bolt 13.

[0026] Specifically, such as Figure 1-3 As shown, one end of the connecting support 1 is bolted to the fixed working arm A, and the other end is bolted to the adjusting support 12. The adjusting support 12 has a slotted hole, which allows for adaptation of the automatic charging mechanism in the length direction via the first bolt 13, avoiding the influence of manufacturing errors in the working arm. The adjusting support 12 is connected to the fixed electrode support 2 via a positioning pin 14, a positioning sleeve 11, and a second bolt 16. A torsion spring 4 and a fixed insulator 10 are mounted on the fixed electrode support 2 via a connecting pin 3, and the torsion spring 4 presses the fixed insulator 10 to prevent poor electrode contact. The fixed insulator 10 is connected to the fixed electrode 5, and the movable insulator 8 is connected to the movable electrode 9 via screws to ensure insulation between the electrode and the metal structure. Terminals 6 are provided on both the fixed electrode 5 and the movable electrode 9 for connecting and drawing current. One end of the movable electrode support 7 is bolted to the telescopic working arm B, and the other end is bolted to the movable insulator 8.

[0027] The connecting pin 3 and the torsion spring 4 can be matched by the installation dimensions so that the torsion spring 4 can provide a torque to rotate around the connecting pin 3 after installation, so that the electrodes can be pressed together when they come into contact, avoiding insufficient charging caused by poor contact. At the same time, it is also necessary to ensure that the magnitude of the torque does not affect the extension and retraction of the working arm.

[0028] The fixed electrode 5 and the movable electrode 9 are made of copper as the base material, which can minimize the space occupied by the charging mechanism while ensuring the charging power. In addition, the contact surfaces of the fixed electrode 5 and the movable electrode 9 are both arc surfaces, which minimizes the wear when the charging mechanism switches states and increases the contact surface contact angle range, reducing the impact on the charging function when the telescopic working arm B is not fully retracted.

[0029] The movable insulator 8 and the fixed insulator 10 isolate the fixed electrode 5 and the movable electrode 9 from the metal structure, avoiding the safety hazards to people around them caused by the conductivity of the metal structure during charging, and also reducing the charging power loss; the two sets of holes on the movable insulator 8 where the movable electrode 9 is installed are staggered, serving as a distinguishing mark between the positive and negative electrodes, and preventing the positive and negative electrodes from being connected incorrectly.

[0030] The adjustment support 12 and the first bolt 13 can be adjusted by adjusting the waist-shaped hole on the support 12 to achieve dimensional adaptation in the length direction of the mechanism, avoiding the influence of cumulative manufacturing errors of the working arm, and also improving the range of working arm sizes applicable to the charging mechanism to a certain extent.

[0031] The positioning bushing 11, the positioning pin 14, and the second bolt 16 can be tightened to move the positioning pin 14 within the positioning bushing 11 along its length direction, and tighten the second bolt 16 to abut against the positioning bushing 11, thereby fixing the adjusting support 12 and the fixed electrode support 2.

[0032] like Figure 4 As shown, when the insulated aerial work platform is in operation, the telescopic boom B extends, the work platform control device is powered by an independent power supply, and the automatic charging mechanism is disconnected to ensure insulated operation performance.

[0033] like Figure 5 As shown, when the insulated aerial work platform is not in operation, the telescopic boom B retracts, the work platform control device is powered off, and the automatic charging mechanism is activated to charge the independent power supply of the work platform, eliminating the need for manual disassembly and carrying of the independent power supply into and out of the work platform.

[0034] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model.
