[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist:

[0005] Common aerial work platforms are typically rectangular hollow structures. Initially, when workers need to climb into the platform, they must first climb onto the support platform at the rear of the vehicle, and then climb into the platform. Due to the limited space at the rear of the vehicle, the process of climbing up and down is inconvenient and unsafe without external tools or personnel assistance. Utility Model Content

[0006] This application provides a convenient access bucket for aerial work to improve the following technical problems:

[0007] In common high-altitude work platforms, without external tools or personnel assistance, the process of workers climbing in and out is not convenient or safe.

[0008] This application provides a convenient access and exit aerial work platform, employing the following technical solution:

[0009] A convenient access aerial work platform includes a platform body and a telescopic ladder. Two sets of symmetrically arranged supports are provided on one side of the platform body, with a gap reserved between the two sets of supports for installing the telescopic ladder in its retracted state. Movable mounting seats are provided on the inner bottom of each support. The top two sides of the telescopic ladder are respectively hinged to the two movable mounting seats. A locking pin is also provided in the middle of the support, used to lock and fix the bottom of the telescopic ladder in its retracted state. A snap-fit ​​seat is also fixedly installed on the side of the work vehicle chassis. The telescopic ladder in its extended state is inclined downwards and snap-fitted into the snap-fit ​​seat.

[0010] In one feasible technical solution of this application, the movable mounting base includes a fixed plate and a hinge shaft. The fixed plate is fixed to the bottom of the bracket, and the hinge shaft is horizontally arranged and rotatably assembled between the fixed plate and the top of the telescopic ladder.

[0011] In one feasible technical solution of this application, a metal part is provided at the top corner of the telescopic ladder. The metal part is a stainless steel block or an aluminum alloy block, and the hinge shaft is rotatably assembled with the metal part.

[0012] In one feasible technical solution of this application, the multiple steps of the telescopic ladder in the storage state are fixed together by straps, and the straps are provided with Velcro or buttons for fixing.

[0013] In one feasible technical solution of this application, the locking pin has two sets, both sets of the locking pin are arranged horizontally and respectively threaded onto the middle of the bracket, and the two sets of the locking pin are respectively used to abut against the two sides of the bottom foot of the telescopic ladder.

[0014] In one feasible technical solution of this application, the locking pin includes a threaded rod and a ring, the middle part of the bracket is provided with a threaded hole for threaded assembly of the threaded rod, and the ring is fixed to the end of the threaded rod away from the telescopic ladder.

[0015] In one feasible technical solution of this application, the snap-fit ​​seat includes a T-shaped plate seat and multiple sets of bolts. The vertical plate portion of the T-shaped plate seat is fixedly installed on the side of the chassis of the work vehicle by the multiple sets of bolts. The horizontal plate portion of the T-shaped plate seat is provided with a snap-fit ​​groove, and the side column of the telescopic ladder can be detachably snapped into the snap-fit ​​groove.

[0016] In one feasible technical solution of this application, the support includes a vertical rod and a plurality of horizontal rods, the two ends of the horizontal rods being respectively connected between the working bucket body and the vertical rod, and both the horizontal rods and the vertical rods are steel pipes.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] In non-high-altitude operation mode, the locking pin can be unlocked, and the telescopic ladder can be rotated to extend it. It can then be fixed to the side of the work vehicle chassis via the locking bracket. In this extended state, the telescopic ladder is tilted downwards, allowing workers to easily enter and exit the work bucket from the ground, which is convenient and safe. When working at height, the telescopic ladder can be rotated upwards and compressed for storage, and then locked in place by the locking pin. In this retracted state, the telescopic ladder, together with the two brackets, forms a guardrail, providing a protective safety effect. This concealed and multifunctional structural design means that the telescopic ladder will not significantly hinder high-altitude operations. It is especially convenient for workers inside the work bucket to quickly unlock, extend, and retract the telescopic ladder themselves, making it very easy to use. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0036] This application discloses a convenient aerial work platform for entry and exit. (Refer to...) Figure 1-3 The convenient access aerial work platform includes a work platform body 1 and a telescopic ladder 2. Two sets of symmetrically arranged brackets 3 are provided on one side of the work platform body 1. A gap is reserved between the two sets of brackets 3 for the installation of the telescopic ladder 2 in the storage state. Movable mounting seats 4 are provided on the inner bottom of the brackets 3. The top two sides of the telescopic ladder 2 are respectively hinged to the two movable mounting seats 4. A locking pin part 5 is also provided in the middle of the brackets 3. The locking pin part 5 is used to lock and fix the bottom feet of the telescopic ladder 2 in the storage state. A snap-fit ​​seat 6 is also fixedly installed on the side of the work vehicle chassis. The telescopic ladder 2 in the extended state is inclined downward and snap-fitted and fixed in the snap-fit ​​seat 6.

[0037] In this embodiment, the movable mounting base 4 includes a fixed plate 41 and a hinge shaft 42. The fixed plate 41 is fixed to the bottom of the bracket 3, and the hinge shaft 42 is horizontally arranged and rotatably assembled between the fixed plate 41 and the top of the telescopic ladder 2. To prevent damage to the top of the telescopic ladder 2 during frequent rotation, a metal part 21 is provided at the top corner of the telescopic ladder 2. The metal part 21 is a stainless steel block or an aluminum alloy block, and the hinge shaft 42 is rotatably assembled with the metal part 21. The movable mounting base 4 designed above has a simple structure, is firmly installed, and can ensure that the telescopic ladder 2 can rotate freely to a suitable angle.

[0038] To prevent the steps 22 of the telescopic ladder 2 from moving freely when it is in the retracted state, the multiple steps 22 of the telescopic ladder 2 in the retracted state are fixed together by straps 7, which are equipped with Velcro or buttons for fixing.

[0039] In this embodiment, there are two sets of locking pins 5, both horizontally arranged and threadedly fitted onto the middle of the bracket 3. The two sets of locking pins 5 are used to abut against both sides of the base of the telescopic ladder 2. Each locking pin 5 includes a threaded rod 51 and a ring 52. A threaded hole for threaded fitting of the threaded rod 51 is provided in the middle of the bracket 3. The ring 52 is fixed to the end of the threaded rod 51 away from the telescopic ladder 2. The locking pins 5 designed above have a simple structure, are easy to install and adjust, and facilitate the fixing and unlocking of the telescopic ladder 2 by workers.

[0040] In this embodiment, the locking seat 6 includes a T-shaped plate seat 61 and multiple sets of bolts 62. The vertical plate portion of the T-shaped plate seat 61 is fixedly installed on the side of the work vehicle chassis by the multiple sets of bolts 62. The horizontal plate portion of the T-shaped plate seat 61 is provided with a locking groove 611, and the side column 23 of the telescopic ladder 2 can be detachably locked into the locking groove 611. The locking seat 6 with the above-described structure is simple in structure and easy to install. The locking effect of the locking groove 611 on the side column 23 of the telescopic ladder 2 makes it easier for workers to stand inside the work bucket body 1 and turn the side column 23 of the telescopic ladder 2 out of the locking groove 611 or turn the side column 23 of the telescopic ladder 2 into the locking groove 611, making the operation more convenient.

[0041] To simplify the structure of the support 3 and reduce its weight, the support 3 includes a vertical rod 31 and multiple horizontal rods 32. The two ends of the horizontal rods 32 are connected between the working bucket body 1 and the vertical rod 31, respectively. Both the horizontal rods 32 and the vertical rods 31 are steel pipes.

[0042] The beneficial technical effects of the convenient access and exit of the aerial work platform in this application embodiment are roughly as follows:

[0043] In non-high-altitude operation mode, the locking pin 5 can be unlocked, and then the telescopic ladder 2 can be rotated to extend it. It can then be fixed to the side of the work vehicle chassis via the locking seat 6. At this time, the telescopic ladder 2 in the extended state is tilted downwards, making it convenient and safe for workers to enter and exit the work bucket directly from the ground. When working at height, the telescopic ladder 2 can be rotated upwards and then compressed and stored, and locked and fixed via the locking pin 5. At this time, the telescopic ladder 2 in the stored state, together with the two brackets 3, forms a barrier and guardrail, which has a protective and safety effect. This hidden and multi-functional structural design means that the presence of the telescopic ladder 2 will not hinder the work bucket from working at height. It is especially convenient for workers inside the work bucket to quickly unlock, unfold, and store and fix the telescopic ladder 2 themselves, making it very convenient to use.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
