Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and in particular to a mobile scissor lift platform. Background Technology

[0002] In the field of high-altitude operations, mobile scissor lifts have been widely used in various scenarios such as construction, equipment installation, and warehousing logistics due to their advantages such as stable structure, high load-bearing capacity, and smooth lifting. However, existing mobile scissor lifts still have several obvious defects in actual use, which restrict their operational efficiency and safety.

[0003] First, traditional platforms typically only have fixed railings around the workbench, which provide basic protection, but operators often have to rely on external ladders or climb from the side of the platform when they want to get on. This is not only cumbersome and inefficient, but also poses safety hazards such as slipping and instability.

[0004] Secondly, although some platforms are equipped with openable fences, their structures are mostly simple disassembly type or side-opening type, which cannot ensure safe enclosure while also providing convenient access to the platform. This significantly increases labor intensity and time costs, especially in situations where workers frequently go up and down.

[0005] In addition, the existing platform's fence system and lifting mechanism lack functional integration, failing to make full use of the structural space to achieve a multi-functional integrated design, resulting in insufficient overall equipment compactness and human-computer interaction experience.

[0006] Therefore, there is an urgent need for a technical solution that can both ensure the safety of high-altitude operations and improve the ease of access to the platform, so as to solve the problem of operators' difficulty in accessing the platform without sacrificing protective performance, thereby improving work efficiency and safety. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this utility model discloses a mobile scissor lift platform.

[0008] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0009] A mobile scissor lift platform includes:

[0010] Car;

[0011] A scissor lift mechanism is installed on a trolley; the scissor lift mechanism is driven by a telescopic cylinder, and a power source for providing power to the telescopic cylinder is installed on the trolley.

[0012] The workbench is installed on top of the scissor lift mechanism;

[0013] Fixed railings are installed on the front and left and right sides of the workbench;

[0014] A flip-up barrier is installed on the back of the workbench; the bottom of the flip-up barrier is hinged to the workbench; when the flip-up barrier is opened downwards, it forms a ladder.

[0015] Preferably, the worktable has an extension structure on its rear side, the extension structure comprising:

[0016] An extension plate, with its two sides connected to the workbench via telescopic slide rails; the flip-up fence is installed on the extension plate;

[0017] Guardrails are installed on both sides of the extension board.

[0018] Preferably, a telescopic rod is installed between the workbench and the extension plate.

[0019] Preferably, a latch assembly is installed between the top two sides of the flip-up fence and the guardrail.

[0020] Preferably, a limit baffle is installed at the position of the flip-up fence corresponding to the pin assembly.

[0021] Preferably, the trolley is equipped with hydraulic outriggers that can extend to both sides on both the front and rear sides.

[0022] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0023] (1) This utility model integrates a scissor lift mechanism on the top of the trolley and uses an electric hydraulic station to drive the hydraulic telescopic cylinder to achieve smooth lifting of the work platform. It is not only compact and reliable in operation, but also easy to move flexibly between different work sites, which significantly improves the mobility and adaptability of high-altitude operations. The work platform is equipped with a protective structure that combines fixed railings and rear flip-up railings. This not only ensures the all-round safety protection of operators when working at height, but also allows the flip-up railings to flip down to form a ladder when at the lowest position, eliminating the trouble of carrying extra ladders and improving the efficiency of climbing onto the platform and the convenience of operation.

[0024] (2) This utility model further adds a retractable extension plate structure to the rear side of the workbench, which is horizontally telescopically connected to the workbench via a slide rail, and works in conjunction with a synchronously moving guardrail to effectively expand the working area. At the same time, it avoids protective gaps caused by the extension plate extending out, ensuring the continuity and integrity of the enclosure structure. The extension length of the extension plate is reasonably limited to less than one-third of the total length of the workbench, balancing the expansion of the working space with the stability of the whole machine. The extension plate is driven by an electric hydraulic station shared with the lifting mechanism, which simplifies the power system, improves energy utilization efficiency, and reduces equipment complexity and maintenance costs.

[0025] (3) This utility model further incorporates a pin assembly and a limiting baffle between the flip-over fence and the guardrail, enabling the flip-over fence to be reliably locked after closing, preventing accidental opening during operation. At the same time, the limiting baffle effectively restricts the flipping stroke, avoiding over-flipping and ensuring accurate locking action, further enhancing the safety and reliability of high-altitude operations. Horizontally extendable hydraulic outriggers are added to the front and rear sides of the trolley. During operation, the outriggers extend outwards and support the ground, significantly enhancing the machine's anti-overturning capability in the parked state. This is particularly suitable for uneven ground or eccentric load conditions, greatly improving the platform's operational stability and safety in complex environments. Attached Figure Description

[0032] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] Example 1:

[0036] Combined with appendix Figures 1-2 A mobile scissor lift platform includes a trolley 1, a scissor lift mechanism 2, and a worktable 3. The trolley 1 serves as the mobile carrier for the entire platform, enabling its overall movement. The scissor lift mechanism 2 is mounted on the upper part of the trolley 1; this mechanism is driven by a telescopic cylinder, and the trolley 1 is equipped with a power source to provide power to the cylinder. The scissor lift mechanism 2 is a mature structure widely used in the prior art, and its specific construction and working principle will not be described in detail in this embodiment. Preferably, the scissor lift mechanism 2 uses a hydraulic telescopic cylinder as its driving element. An electro-hydraulic station is mounted on the trolley 1 to drive the hydraulic telescopic cylinder to perform telescopic movements, thereby controlling the lifting motion of the scissor lift mechanism 2 and achieving height adjustment of the worktable 3.

[0037] A work platform 3 is fixedly installed on top of the scissor lift mechanism 2, allowing operators to perform high-altitude work. To ensure operator safety, fixed guardrails 4 are installed on the front, left, and right sides of the work platform 3. A flip-up guardrail 5 is installed on the rear side of the work platform 3. Specifically, the bottom of the flip-up guardrail 5 is connected to the rear edge of the work platform 3 via a hinge structure, allowing it to flip downwards around the hinge axis. When the scissor lift mechanism 2 descends to its lowest position, the work platform 3 still maintains a certain height above the ground. At this time, the operator can flip the flip-up guardrail 5 downwards, unfolding it to form a ladder structure that can be climbed. Using this ladder, the operator can directly climb onto the work platform 3 without carrying or using additional ladders, improving convenience and work efficiency. After climbing, the operator can flip the flip-up guardrail 5 upwards to reset it, closing it and connecting it with the fixed guardrails 4 on the left and right sides of the work platform 3, thus forming a complete protective structure around the work platform 3, providing all-round safety protection for the operator.

[0038] Example 2:

[0039] Combined with appendix Figures 1-4A mobile scissor lift platform is disclosed, whose overall structure is based on Embodiment 1, but with functional extensions. Specifically, an extension structure is added to the rear side of the workbench 3, which includes an extension plate 6 and a guardrail 7. The left and right sides of the extension plate 6 are telescopically connected to corresponding parts of the workbench 3 via telescopic slide rails, allowing the extension plate 6 to extend horizontally towards the rear of the workbench 3 along the slide rail direction, thereby effectively expanding the working area of ​​the workbench 3 and increasing the operator's activity space.

[0040] To ensure the structural stability of the machine during operation, the outward extension length of the extension plate 6 is limited, and its maximum extension length must not exceed one-third of the total length of the workbench 3. The flip-up guardrail 5 is installed on the rear edge of the extension plate 6 and can move synchronously with the extension and retraction of the extension plate 6. Guardrails 7 are provided on the left and right sides of the extension plate 6. When the extension plate 6 extends outward, the guardrails 7 also extend synchronously to cover the gap formed between the flip-up guardrail 5 and the fixed guardrails 4 on both sides of the workbench 3 due to the extension of the extension plate 6, thereby maintaining the continuity and integrity of the enclosure structure and ensuring the safety of the operators.

[0041] Furthermore, a telescopic rod 8 is provided between the workbench 3 and the extension plate 6. This telescopic rod 8 is used to drive the extension plate 6 to extend or retract. The telescopic rod 8 can share the same power source as the hydraulic telescopic cylinder in the scissor lift mechanism 2, that is, it is powered by the electric hydraulic station installed on the trolley 1, which simplifies the system structure and improves energy efficiency. In addition, as shown in the attached... Figure 4 As shown, latch assemblies 9 are provided on the left and right sides of the top of the flip-up fence 5 and between them and the corresponding guardrails 7. These assemblies are used to lock the flip-up fence 5 to the guardrails 7 after it is closed, preventing the flip-up fence 5 from being accidentally opened during operation. A limiting baffle 10 is also provided on the flip-up fence 5 at the position corresponding to the latch assembly 9. When the flip-up fence 5 is flipped upward to the closed position, the limiting baffle 10 contacts the guardrail 7, which serves to limit the flip-up fence 5 from over-flipping due to inertia or external force. It also helps the latch assembly 9 to complete the locking action quickly and accurately.

[0042] Example 3:

[0043] Combined with appendix Figure 1 and 5 A mobile scissor lift platform, based on Embodiment 1 or Embodiment 2, further incorporates a stable support structure. Specifically, hydraulic outriggers 11 are installed on both the front and rear sides of the trolley 1, each hydraulic outrigger 11 capable of extending horizontally to the corresponding side of the trolley 1. (See attached diagram.) Figure 5As shown, the hydraulic outriggers 11 are telescopically connected to the trolley 1 via retractable connecting rods. When the platform is in parking operation, the operator can control the four hydraulic outriggers 11 to extend outwards simultaneously, extending them to the ground areas on the left and right sides of the trolley 1 respectively. Then, the supporting ends of the hydraulic outriggers 11 contact the ground and apply supporting force, thereby significantly improving the support stability of the entire machine in operation, preventing the risk of overturning due to uneven ground or load shift, and ensuring the safety and reliability of high-altitude operations.

[0044] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
