Description

Technical Field

[0001] The present invention relates to the technical field of scissor lift platforms, and more specifically, to a multifunctional working platform for a scissor lift platform, and more particularly to an aerial work system comprising the multifunctional working platform for a scissor lift platform. Background Art

[0002] In the prior art, a scissor lift platform (hereinafter referred to as a scissor lift platform) is a lift platform that uses a scissor lift structure as an extension mechanism. The extension of the scissor lift structure can be used to carry personnel, tools and materials to the work location. It is widely used in the fields of construction, warehousing and logistics, shipbuilding, airports, indoor and outdoor decoration, large exhibition halls, etc. The basic structure of the scissor lift platform includes a working platform 1, an extension mechanism 2, a chassis assembly 3, etc. Figure 1 and Figure 2 shown.

[0003] Among them, the working platform 1 includes a main platform 1-1, an extension platform 1-2, a guardrail 1-3, an upper control operation box 1-4, a platform roller 1-5, a hinge shaft 1-6, and a connecting harness 1-7. The main platform 1-1 is the bearing body of the working platform. The lower part of the main platform 1-1 is connected to the extension mechanism 2, and the upper part of the main platform 1-1 is provided with an extension platform 1-2 and a guardrail 1-3. The extension platform 1-2 is connected to the main platform through the platform roller 1-5, and has an extension function, which can expand the operating range of the operator. The guardrail 1-3 is distributed around the working platform 1, and is connected to the main platform 1-1 or the extension platform 1-2 through the hinge shaft 1-6, and is used to prevent people, tools or materials from falling. The upper control operation box 1-4 is generally hung on the guardrail 1-3, and is used for the operator to control the scissor platform on the working platform 1, and the upper control operation box 1-4 is connected to the electric control system through the connecting harness 1-7.

[0004] Based on the above structure, the working platform of the traditional scissor lift platform only has platform extension, guardrail protection and high-position control functions. However, when the operator is performing high-position operations, especially lifting operations under some complex building structures, due to the limitation of the field of vision, the working platform may be too close to the building or even contact the building, which may cause equipment damage and casualties in serious cases.

[0005] In summary, how to transform the working platform to provide safety warnings for operators under complex construction conditions and ensure the safety of personnel and equipment is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a multifunctional working platform for a scissor lift platform, which is modified on the basis of the original working platform and can provide safety warnings for operators under complex construction conditions (i.e., the anti-collision device promptly feeds back a stop operation signal to the electronic control system) to ensure the safety of personnel and equipment.

[0007] Another object of the present invention is to provide an aerial work system comprising the multifunctional working platform for the scissor platform.

[0008] In order to achieve the above object, the present invention provides the following technical solutions:

[0009] A multifunctional working platform for a scissor lift platform, comprising:

[0010] A working platform, comprising a main platform and an extension platform telescopic relative to the main platform;

[0011] A guardrail is provided along the periphery of the working platform;

[0012] An upper control operation box, which is hung on the guardrail, and the upper control operation box is connected to the electric control system of the working platform through a connecting harness;

[0013] A safety foot switch, which is arranged on the extension platform, and the safety foot switch is connected to the electric control system through the connecting harness;

[0014] An anti-collision device, which is movably arranged on the working platform, and is used to feed back a stop operation signal to the electric control system when the working platform is lifted to a limited height;

[0015] A wire harness drag chain is arranged between the main platform and the extension platform, and the wire harness drag chain moves following the extension platform, and the connecting wire harness is arranged in the wire harness drag chain.

[0016] In one embodiment, a receiving groove for receiving the extension platform is provided under the main platform, the extension platform is connected to the main platform via platform rollers, and the extension platform is fixed to the main platform via a locking member when it is extended to a preset position.

[0017] In one embodiment, the guardrail is connected to the main platform or the extension platform via a hinge shaft.

[0018] In one embodiment, the anti-collision device includes an anti-collision bar seat arranged on the working platform, a top anti-collision bar movably arranged on the anti-collision bar seat, and a top-touch switch arranged on the top of the top anti-collision bar, and the top-touch switch is connected to the electronic control system through the connecting wiring harness.

[0019] In one embodiment, the anti-collision bar seats are arranged at the four corners of the guardrail.

[0020] In one embodiment, the anti-collision bar seat is fixed to the guardrail by bolts, or the anti-collision bar seat is welded to the guardrail.

[0021] In one embodiment, the top anti-collision bar is movable up and down relative to the anti-collision bar seat, the top anti-collision bar and the anti-collision bar seat are both axially provided with mounting holes, and the top anti-collision bar is fixed to the anti-collision bar seat by a fixing member.

[0022] In one embodiment, the main platform is provided with a towline mounting seat and a harness protection cover, the extension platform is provided with the harness towline and the towline cover, and the bottom of the extension platform is provided with a harness groove; the harness entry end of the harness towline is provided above the towline mounting seat, and the harness output end of the harness towline is provided on the extension platform;

[0023] The wire harness protection cover and the drag chain mounting seat are arranged at the same position of the main platform to protect the drag chain mounting seat and the connecting wire harness entering the working platform. The drag chain cover and the wire harness drag chain are arranged at the same position of the extension platform to protect the wire harness drag chain and the connecting wire harness installed inside the wire harness drag chain. The wire harness groove is used to protect the connecting wire harness installed in the wire harness groove.

[0024] A high-altitude work system comprises any of the multifunctional working platforms for scissor platforms described above.

[0025] When using the multifunctional working platform for scissor platforms provided by the present invention, the extension platform can be extended forward a certain distance relative to the main platform to achieve the purpose of expanding the operating range of the operator. Guardrails are distributed around the working platform to effectively prevent operators, tools or materials from falling. The upper control operation box is used for operators to control the equipment on the working platform, and the upper control operation box is connected to the electronic control system through a connecting harness. The safety foot switch is installed on the extension platform and connected to the electronic control system through a connecting harness. When operating the equipment, the operator must first step on the safety foot switch with his foot to trigger the safety foot switch. Then, the safety foot switch sends a signal to the electronic control system through the connecting harness, and the electronic control system will allow the equipment to operate to avoid the equipment being accidentally started.

[0026] When transporting or transferring equipment, the height of the anti-collision device can be adjusted to the lowest position to reduce the total height of the equipment and improve the height passability of the equipment. When the equipment needs to be lifted, the height of the anti-collision device can be adjusted to the highest position to provide operators with sufficient operating safety range. At the same time, if the anti-collision device detects that the working platform has been lifted to the restricted height during the lifting process of the equipment, the anti-collision device can promptly feedback the stop operation signal to the electronic control system to prevent the working platform from continuing to lift and contacting the building, causing equipment damage and casualties.

[0027] In addition, the harness drag chain is installed between the main platform and the extension platform, and the connection harness is installed inside the harness drag chain. When the extension platform is extended, the connection harness can move with the extension platform through the movement of the harness drag chain. The harness drag chain can effectively protect the connection harness and avoid damage to the connection harness during use.

[0028] In summary, the multifunctional working platform for the scissor lift platform provided by the present invention is modified on the basis of the original working platform, and can provide safety warnings for operators under complex construction conditions (i.e., the anti-collision device promptly feeds back a stop operation signal to the electronic control system), thereby ensuring the safety of personnel and equipment.

[0029] In addition, the present invention also provides an aerial work system including the multifunctional working platform for the scissor-type platform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The core of the present invention is to provide a multifunctional working platform for a scissor platform, which is modified on the basis of the original working platform and can provide safety warnings for operators under complex construction conditions (i.e., the anti-collision device promptly feeds back a stop signal to the electric control system), thereby ensuring the safety of personnel and equipment. Another core of the present invention is to provide an aerial work system including the multifunctional working platform for a scissor platform.

[0044] Please refer to Figures 3 to 8 , Figure 3 A schematic diagram of the structure of the aerial work system provided by the present invention; Figure 4 A schematic structural diagram of a multifunctional working platform for a scissor lift platform provided by the present invention; Figure 5It is a structural schematic diagram of a multifunctional working platform for a scissor-type platform from another perspective; Figure 6 for Figure 5 A local enlarged schematic diagram of the middle A; Figure 7 A top view of a multifunctional working platform for a scissor platform; Figure 8 It is a structural schematic diagram of the anti-collision device.

[0045] This specific embodiment provides a multifunctional working platform for a scissor platform, comprising:

[0046] A working platform 1', comprising a main platform 1-1' and an extension platform 1-2' telescopic relative to the main platform 1-1';

[0047] Guardrails 1-3' are arranged around the working platform 1';

[0048] An upper control operation box 1-4' is hung on the guardrail 1-3', and the upper control operation box 1-4' is connected to the electric control system of the working platform 1' through a connecting harness 1-7';

[0049] A safety foot switch 1-8' is arranged on the extension platform 1-2', and the safety foot switch 1-8' is connected to the electric control system through a connecting harness 1-7';

[0050] An anti-collision device, which is movably mounted on the working platform 1', and is used to feed back a stop signal to the electric control system when the working platform 1' is lifted to a limited height;

[0051] The harness drag chain 1-12' is arranged between the main platform 1-1' and the extension platform 1-2', and the harness drag chain 1-12' moves following the extension platform 1-2', and a connecting harness 1-7' is arranged inside the harness drag chain 1-12'.

[0052] It should be noted that the basic structure of the scissor platform of the present application includes a working platform 1', an extension mechanism 2' and a chassis assembly 3' to constitute the aerial work system of the present invention. The present application mainly improves and optimizes the working platform 1', and the extension mechanism 2' and the chassis assembly 3' can be set with reference to the common structures of the prior art. In the present application, the upper control operation box 1-4', the safety foot switch 1-8' and the anti-collision device can be connected to the electronic control system through the connecting harness 1-7'. In order to protect the connecting harness 1-7' from being damaged when the extension platform 1-2' is extending, a harness drag chain 1-12' is provided between the main platform 1-1' and the extension platform 1-2', and the connecting harness 1-7' is installed inside the harness drag chain 1-12' to protect the connecting harness 1-7'. Moreover, when the operator first steps on the safety foot switch 1-8' with his foot, the safety foot switch 1-8' is triggered, and the safety foot switch 1-8' sends a signal to the electronic control system through the connecting harness 1-7', and the electronic control system allows the equipment to operate. In addition, the anti-collision device can provide an adequate safety operation warning range for the operator when performing lifting operations under complex construction conditions, ensuring the safety of the operator and the equipment.

[0053] It should also be noted that in addition to the common platform extension, guardrail protection and high-position control functions, this device is also designed with safety pedals (safety foot switch 1-8'), top collision protection (anti-collision device) and wire harness protection (wire harness drag chain 1-12'). For example, the safety pedal function requires the operator to step on the safety foot switch 1-8' to activate the equipment operation, which can ensure that the equipment will not continue to operate or be misoperated when the operator is resting or an accident occurs.

[0054] The top anti-collision function can provide operators with a sufficient safe operation warning range when performing lifting operations under complex construction conditions, ensuring the safety of operators and equipment. The harness protection function is to use the harness drag chain 1-12' to protect the connecting harness 1-7' of the extended part of the working platform 1', reducing the risk of damage to the connecting harness 1-7' due to exposure and the movable extension platform 1-2'. The above functions strengthen the traditional working platform in terms of operating scope, equipment operation and harness protection, providing multiple safety guarantees for operators working under complex construction conditions, ensuring the safety of personnel and equipment.

[0055] In actual use, the shape, structure, size, etc. of the working platform 1', guardrails 1-3', upper control box 1-4', safety foot switch 1-8', anti-collision device and harness drag chain 1-12' can be determined according to actual conditions and actual needs.

[0056] When using the multifunctional working platform for scissor platforms provided by the present invention, the extension platform 1-2' can be extended forward a certain distance relative to the main platform 1-1' to achieve the purpose of expanding the operating range of the operator. The guardrails 1-3' are distributed around the working platform 1', which can effectively prevent the operator, tools or materials from falling. The upper control operation box 1-4' is used for the operator to control the equipment on the working platform 1', and the upper control operation box 1-4' is connected to the electric control system through the connecting harness 1-7'. The safety foot switch 1-8' is installed on the extension platform 1-2' and is connected to the electric control system through the connecting harness 1-7'. When the operator operates the equipment, he must first step on the safety foot switch 1-8' with his foot to trigger the safety foot switch 1-8', and then the safety foot switch 1-8' sends a signal to the electric control system through the connecting harness 1-7', and the electric control system will allow the equipment to operate to avoid the equipment being accidentally started.

[0057] When the equipment is transported or transferred, the height of the anti-collision device can be adjusted to the lowest position to reduce the total height of the equipment and improve the height passability of the equipment. When the equipment needs to be lifted, the height of the anti-collision device can be adjusted to the highest position to provide operators with sufficient operating safety range. At the same time, if the anti-collision device detects that the working platform 1' is lifted to the restricted height during the lifting process of the equipment, the anti-collision device can promptly feedback the stop operation signal to the electronic control system to prevent the working platform 1' from continuing to lift and contacting the building, causing equipment damage and casualties.

[0058] In addition, the harness drag chain 1-12' is installed between the main platform 1-1' and the extension platform 1-2', and the connection harness 1-7' is installed inside the harness drag chain 1-12'. When the extension platform 1-2' is extending, the connection harness 1-7' can move with the extension platform 1-2' through the movement of the harness drag chain 1-12'. The harness drag chain 1-12' can effectively protect the connection harness 1-7' and avoid damage to the connection harness 1-7' during use.

[0059] In summary, the multifunctional working platform for the scissor lift platform provided by the present invention is modified on the basis of the original working platform, and can provide safety warnings for operators under complex construction conditions (i.e., the anti-collision device promptly feeds back a stop operation signal to the electronic control system), thereby ensuring the safety of personnel and equipment.

[0060] In one embodiment, a receiving groove for receiving the extension platform 1-2' is provided below the main platform 1-1', and the extension platform 1-2' is connected to the main platform 1-1' via the platform roller 1-5'. When the extension platform 1-2' is extended to a preset position, it is fixed to the main platform 1-1' via a locking member. Therefore, when it is necessary to expand the area of ​​the working platform 1', the extension platform 1-2' can be pulled outward, and the extension platform 1-2' moves smoothly under the drive of the platform roller 1-5'. When the extension platform 1-2' moves to the preset position, it is fixedly connected to the main platform 1-1' via a locking member. When it is necessary to reduce the area of ​​the working platform 1', the extension platform 1-2' can be pushed inward, and the extension platform 1-2' moves smoothly in the opposite direction under the drive of the platform roller 1-5'. When the extension platform 1-2' moves to another preset position, it is fixedly connected to the main platform 1-1' via a locking member.

[0061] In one embodiment, the guardrail 1 - 3 ′ is connected to the main platform 1 - 1 ′ or the extension platform 1 - 2 ′ via a hinge shaft 1 - 6 ′.

[0062] In one embodiment, Figure 8 As shown, the anti-collision device includes an anti-collision rod seat 1-9' arranged on the working platform 1', a top anti-collision rod 1-10' movably arranged on the anti-collision rod seat 1-9', and a top-touching switch 1-11' arranged on the top of the top anti-collision rod 1-10', and the top-touching switch 1-11' is connected to the electronic control system through a connecting harness 1-7'.

[0063] It should be noted that the top anti-collision bar 1-10' is movably arranged on the anti-collision bar seat 1-9', which means that the top anti-collision bar 1-10' can be raised and lowered relative to the anti-collision bar seat 1-9' to adjust the maximum height of the device. When the equipment is transported or transferred, the height of the top anti-collision bar 1-10' can be adjusted to the lowest position to reduce the total height of the equipment and improve the height passability of the equipment. When the equipment needs to be lifted, the height of the top anti-collision bar 1-10' can be adjusted to the highest position. The highest position of the top anti-collision bar 1-10' is generally equal to the maximum platform operating height allowed by the equipment (2m), providing operators with sufficient operating safety range.

[0064] Moreover, a top switch 1-11' is installed at the top end of the top anti-collision rod 1-10', which is connected to the electric control system through the connecting harness 1-7'. When the top switch 1-11' touches an obstacle during the lifting operation of the equipment, the top switch 1-11' is triggered and sends a signal to the electric control system through the connecting harness 1-7'. The electric control system immediately prohibits the operation of the equipment to avoid collision damage to the equipment or the operator.

[0065] In one embodiment, the anti-collision rod seats 1-9' are arranged at the four corners of the guardrail 1-3'.

[0066] It should be noted that in order not to increase the outer width of the equipment and not to affect the internal working space of the working platform 1', the anti-collision device is arranged between the transverse guardrail and the longitudinal guardrail of the working platform 1', rather than on the inside or outside of the working platform 1'. Therefore, the anti-collision bar seat 1-9' can be set at the four corners of the guardrail 1-3', that is, the anti-collision bar seat 1-9' is set at the four corners of the working platform 1', and the highest position of the top anti-collision bar 1-10' is generally equal to the maximum platform operating height allowed by the equipment (2m).

[0067] In one embodiment, the anti-collision rod seat 1-9' is fixed to the guardrail 1-3' by bolts, or the anti-collision rod seat 1-9' is welded to the guardrail 1-3' to ensure that the anti-collision rod seat 1-9' is firmly fixed to the guardrail 1-3'.

[0068] In one embodiment, the top anti-collision bar 1-10' is lifted and lowered relative to the anti-collision bar seat 1-9', and both the top anti-collision bar 1-10' and the anti-collision bar seat 1-9' are provided with mounting holes along the axial direction, and the top anti-collision bar 1-10' is fixed to the anti-collision bar seat 1-9' by a fixing piece. Therefore, the top anti-collision bar 1-10' can be moved up and down during use, and after the top anti-collision bar 1-10' moves to the desired height position, the two aligned mounting holes are locked by the fixing piece to fix the top anti-collision bar 1-10' on the anti-collision bar seat 1-9'.

[0069] In one embodiment, Figure 5 and Figure 6 As shown, a drag chain mounting seat 1-13' and a harness protection cover 1-14' are provided on the main platform 1-1', a harness drag chain 1-12' and a drag chain cover 1-15' are provided on the extension platform 1-2', and a harness groove 1-16' is provided at the bottom of the extension platform 1-2'; the harness entry end of the harness drag chain 1-12' is provided above the drag chain mounting seat 1-13', and the harness output end of the harness drag chain 1-12' is provided on the extension platform 1-2';

[0070] The harness protection cover 1-14' and the drag chain mounting base 1-13' are arranged at the same position of the main platform 1-1' to protect the drag chain mounting base 1-13' and the connecting harness 1-7' entering the working platform 1'. The drag chain cover 1-15' and the harness drag chain 1-12' are arranged at the same position of the extension platform 1-2' to protect the harness drag chain 1-12' and the connecting harness 1-7' installed inside the harness drag chain 1-12'. The harness groove 1-16' is used to protect the connecting harness 1-7' installed in the harness groove 1-16'.

[0071] It should be noted that in the prior art, the connection harness 1-7 of the working platform 1 is connected from the main platform 1-1 and connected to the upper control box 1-4 along the guardrail 1-3 of the extension platform 1-2. In the process of the extension platform 1-2 extending to the front of the equipment, the length of the connection harness 1-7 needs to be increased as the extension platform 1-2 extends. The traditional scissor-type platform will design the connection harness 1-7 from the main platform 1-1 to the extension platform 1-2 as a spiral spring harness, which is suspended under the guardrail 1-3 of the extension platform 1-2 by a cable tie or a fixed hook, and the connection harness 1-7 has basically no device. When the operator is working, the connection harness 1-7 is often hooked or scratched by tools, materials or foreign objects in the construction environment, causing the connection harness 1-7 to be damaged, and in severe cases, it may even be cut off, causing equipment failure.

[0072] However, in the present application, the connecting wire harness 1-7' is connected from the main platform 1-1', enters the wire harness drag chain 1-12' from the wire harness entry end of the wire harness drag chain 1-12', and then reaches the extension platform 1-2' from the wire harness output end of the wire harness drag chain 1-12', passes through the wire harness groove 1-16' at the bottom of the extension platform 1-2' and is connected to the upper control operation box 1-4'. The part of the connecting wire harness 1-7' on the main platform 1-1' is protected by the wire harness protection cover 1-14', the part of the connecting wire harness 1-7' in the wire harness drag chain 1-12' is protected by the wire harness drag chain 1-12', and the part of the connecting wire harness 1-7' in the wire harness groove 1-16' is protected by the wire harness groove 1-16'. There is no need to use a coil spring wire harness for the connecting wire harness 1-7' of the working platform 1'. That is, under the premise of satisfying the extension function of the connecting harness 1-7', the exposed length of the connecting harness 1-7' is reduced, the hidden danger of the connecting harness 1-7' being damaged due to being exposed is eliminated, and the failure rate of the equipment is reduced.

[0073] In addition to the above-mentioned multifunctional working platform for the scissors-lift platform, the present invention also provides an aerial work system including the multifunctional working platform for the scissors-lift platform disclosed in the above-mentioned embodiment.
