Description

Technical Field

[0001] This utility model relates to the field of aerial work platform technology, specifically to an aerial work platform. Background Technology

[0002] Aerial work platforms consist of a vehicle body and a liftable work platform. They are specialized engineering vehicles used to elevate personnel to high altitudes for work, with the work platform being a personnel basket. Most existing work platforms have hinged, swing-out doors that are locked using a mechanical bolt lock.

[0003] In actual operation, it was found that there may be hidden dangers of doors being accidentally opened or unlocked. In the event of doors being accidentally opened or unlocked, it is not easy to be discovered and there is a lack of warning. Hinged doors are relatively easier to be fully opened, exposing the user to a dangerous environment. In addition, it was found that the working space inside the aerial work platform is limited, and the protection height is restricted. If the protection is too high, it is difficult to extend the arms to operate during the operation. If the protection is too low, there are also certain safety hazards.

[0004] Based on the above problems, in order to improve the safety and protection of high-altitude operations, the working platform of the aerial work vehicle has been further improved, and a new aerial work vehicle working platform has been provided. Utility Model Content

[0005] The purpose of this utility model is to provide a working platform for aerial work vehicles, which solves the problem of improving the safety and protection of aerial work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a working platform for an aerial work vehicle, comprising a working platform and a sliding door. The working platform includes an enclosed work bucket, a protective fence fixed to the top of the work bucket, and an extended guardrail fixed to the outside of the protective fence and extending diagonally upward. One side of the working platform has an entrance, and a sliding door is provided at the entrance. The sliding door is slidably mounted on the working platform via a sliding rail mechanism. A buzzer alarm magnetic lock and a manual bolt lock are respectively provided between the working platform and the sliding door for locking.

[0007] Preferably, the height of the inlet is higher than the ground level of the work vehicle's bucket.

[0008] Preferably, the slide rail mechanism includes a ground rail and two sets of auxiliary handle slide rails.

[0009] Preferably, the ground track is laid on the ground of the work vehicle bed along the sliding door's translational trajectory, and the bottom of the sliding door is slidably mounted on the ground track.

[0010] Preferably, the two sets of auxiliary handle rails are respectively installed on the outer and inner sides of the sliding door;

[0011] The auxiliary handle slide rail is fixed to the work vehicle bed, and the handle slide rail is fixed to the sliding door and slidably set on the fixed slide rail.

[0012] Preferably, the manual latch lock is located inside the work truck bed and installed between the work truck bed and the sliding door;

[0013] The manual latch lock is fixed in place along the vertical sliding direction of the sliding door.

[0014] Preferably, the buzzer alarm magnetic lock includes a buzzer alarm module and an LED display module;

[0015] The magnetic lock with buzzer alarm has a built-in position sensor. The position sensor detects the bolt status signal and sends it to the built-in logic control unit. The output of the logic control unit is connected to the buzzer alarm module and the LED display module, respectively.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model features a work platform, a sliding door, and a buzzer-alarm magnetic lock. The work platform is designed with an enclosed work basket to enhance safety and prevent items from falling out. The extended guardrails increase the height of protection on the work platform. The sliding door offers higher safety performance than a swing door, as it is less likely to be opened and expose the entrance. The buzzer-alarm magnetic lock on the work platform can alert the user to the status of the sliding door when it is closed, thus improving the safety and reliability of the operation.

[0018] 2. This utility model improves the stability of the sliding door by setting up a slide rail mechanism and a manual bolt lock. The slide rail mechanism improves the stability of the sliding door, and the auxiliary handle of the slide rail mechanism acts as a handle, making it easy to operate. The addition of a manual bolt lock can be used according to specific needs. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5 As shown, this utility model provides a technical solution: a working platform for an aerial work vehicle, including a working platform 1 and a sliding door 2. The working platform 1 includes an enclosed working truck bed 11, a protective railing 12 fixed to the top of the working truck bed 11, and an extended guardrail 13 fixed to the outside of the protective railing 12 and extending obliquely upward. The enclosed working truck bed 11 has good protective performance, and tools placed in the enclosed working truck bed 11 will not fall out. The use of the extended guardrail 13 to increase the protective height avoids the shortcomings of restricting the operator's arms from reaching out to work compared to the direct extension height.

[0027] One side of the work platform 1 has an entrance 14, which is higher than the ground level of the work truck bed 11, providing good protection. A sliding door 2 is installed at the entrance 14 on the work platform 1. The sliding door 2 is slidably mounted on the work platform 1 via a sliding rail mechanism 3. The sliding rail mechanism 3 includes a ground rail 31 and two sets of auxiliary handle rails 32. The ground rail 31 is laid on the ground of the work truck bed 11 along the sliding door 2's trajectory, and the bottom of the sliding door 2 is slidably mounted on the ground rail 31. The two sets of auxiliary handle rails 32 are respectively... The auxiliary handle slide rail 32 is placed on the outside and inside of the sliding door 2; the fixed slide rail 321 of the auxiliary handle slide rail 32 is fixed on the work vehicle 11, and the handle slide rail 322 of the auxiliary handle slide rail 32 is fixed on the sliding door 2 and slidably set on the fixed slide rail 321; the combination of the ground rail 31 and the auxiliary handle slide rail 32 improves the stability of the sliding door 2 during installation and sliding, and makes room for workers to enter and exit after the sliding door 2 is opened. The auxiliary handle slide rail 32 serves as a handle on both the outside and inside of the sliding door 2, making it convenient to use.

[0028] A buzzer-alarm magnetic lock 4 and a manual bolt lock 5 are respectively installed between the work platform 1 and the sliding door 2. During operation, either the buzzer-alarm magnetic lock 4 or the manual bolt lock 5 can be used as needed. Both locks are provided to improve the product's security. The manual bolt lock 5 is located inside the work truck bed 11 and installed between the work truck bed 11 and the sliding door 2. The manual bolt lock 5 is locked and fixed along the direction perpendicular to the sliding door 2.

[0029] The buzzer alarm magnetic lock 4 includes a buzzer alarm module 41 and an LED display module 42;

[0030] The buzzer-alarm magnetic lock 4 has a built-in position sensor 43. The bolt status signal detected by the position sensor 43 is sent to the built-in logic control unit 44. The output of the logic control unit 44 is connected to the buzzer alarm module 41 and the LED display module 42 respectively. When the bolt is not locked, the bolt unlock status signal detected by the position sensor 43 is sent to the built-in logic control unit 44. The logic control unit 44 controls the buzzer alarm module 41 to sound an alarm and controls the LED display module 42 to light up a warning light (such as a red light). When the bolt is locked, the bolt locking status signal detected by the position sensor 43 is sent to the built-in logic control unit 44. The logic control unit 44 controls the LED display module 42 to light up a warning light (such as a green light).
