Description

Technical Field

[0001] This utility model belongs to the field of oil and gas exploration equipment. More specifically, this utility model relates to a foldable operating platform. Background Technology

[0002] Fracturing is a primary measure in oil and gas field exploration and development, and the fracturing truck is the key equipment in fracturing operations. The core component of the fracturing truck is the fracturing pump, which consists of a power end and a hydraulic end. The hydraulic end requires frequent maintenance during operation. The fracturing pump is typically mounted on the chassis beam, with its width roughly matching the width of the entire vehicle, resulting in insufficient space for maintenance operations on the side of the hydraulic end.

[0003] Currently, to facilitate maintenance operations on the hydraulic system, a common practice is to install a pull-out operating platform on the chassis platform below the hydraulic system. When the vehicle is in motion, the operating platform is retracted to prevent the equipment from exceeding its width; when maintenance is required, the platform is pulled out for personnel to stand on. However, these pull-out operating platforms are often designed to be quite bulky to meet load-bearing and structural strength requirements, resulting in laborious and inefficient retraction and deployment. Furthermore, due to the pull-out structure, the effective operating space of the platform is usually small, causing considerable inconvenience for maintenance personnel. In addition, ensuring that the operating platform can be reliably secured after retraction, without affecting the vehicle's driving width and complying with regulations, is also a problem that urgently needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to provide a foldable operating platform to address the shortcomings of existing technologies. This invention aims to achieve rapid and convenient folding and unfolding of the operating platform, ensuring that it does not increase vehicle width when folded, thus complying with vehicle road regulations. Simultaneously, through optimized structural design, the effective usable space of the operating platform is expanded, and a stable and safe working environment is provided for the operator.

[0005] The technical solution adopted by this utility model to solve this technical problem is: a foldable operating platform, including a support arm assembly, an operating platform, a left column assembly and a right column assembly; The support arm assembly includes a support arm, one end of which is connected to the frame via a pin c. The support arm can rotate horizontally around the pin c and is in close contact with the edge of the frame when folded up. The operating platform is set at the corresponding position on the vehicle frame. The operating platform is connected to the vehicle frame through pin a and can be rotated up and down around pin a. In the unfolded state, it is supported by the support arm assembly. The left and right column assemblies are equipped with limiting devices for fixing the operating platform when it is folded to a vertical position.

[0006] As a further embodiment of this utility model, the support arm is provided with a hole. When the support arm is rotated to be parallel to the side of the frame, the support arm is fixed by passing a pin a through the hole and the corresponding hole on the frame.

[0007] As a further embodiment of this utility model, the limiting device is a sliding pin or locking block structure. When the operating platform is flipped to a vertical position, the sliding limiting device engages and fixes it with the corresponding part on the operating platform.

[0008] As a further embodiment of this utility model, it also includes a guardrail, wherein the upright of the guardrail is inserted into the bushing at the other end of the support arm, and the two can rotate freely between them.

[0009] As a further embodiment of this utility model, the left column assembly and the right column assembly are symmetrical structures, each equipped with a protective door connected by a pin. The protective door can be rotated around the pin to open or close, and is fixed by a latch.

[0010] This utility model has at least the following beneficial effects: 1. Solved the problem of excessive vehicle width: Through the horizontal rotation of the support arm and the folding design of the platform flipping up and down, the entire device can be tightly folded into the side of the frame when not in use, without increasing the width of the vehicle. This ensures that the vehicle meets the regulations for road driving and can be properly registered and licensed.

[0011] 2. Easy and efficient operation: Compared with the traditional bulky pull-out platform, the flipping and rotating structure of this invention is more labor-saving, realizing the rapid unfolding and folding of the operating platform, significantly reducing the labor intensity of operators and improving the efficiency of maintenance operations.

[0012] 3. Provides a stable and safe working space: After the platform is deployed, it is reliably supported by the outrigger assembly, ensuring stable load-bearing capacity; together with the fixable guardrails and safety doors, it creates a safe and spacious working area for operators, effectively preventing the risk of falls from heights.

[0013] 4. Reliable storage and fixation: The outrigger in the folded state and the operating platform in the folded state are fixed by the pin and the limiting device on the column, which effectively avoids abnormal noise, loosening or accidental unfolding caused by shaking and vibration during vehicle operation, thus ensuring driving safety.

[0014] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in detail and completely with reference to the accompanying drawings. Those skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention with reference to the accompanying drawings, it should be particularly noted that the technical solutions and features provided in the various parts of the present invention, including the following description, can be combined with each other without conflict.

[0018] Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the protection scope of the present invention.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, and the specific implementation process is as follows: See attached document Figure 1 To be continued Figure 5 This utility model provides a foldable operating platform, including a support arm assembly 7, an operating platform 4, a left column 501 assembly 5, and a right column 501 assembly 2.

[0020] The support arm assembly 7 includes a support arm 701, with bushings at both ends. One end of the support arm 701 is connected to the ear plate d703 on the side of the frame 1 via a pin c702. Through this pin c702 connection, the support arm 701 can rotate horizontally around the pin c702. When the platform 401 is not in use, the support arm 701 can rotate to a position parallel to the side of the frame 1, making it close to the edge of the frame 1, thus not increasing the vehicle's width. Figure 2 As shown.

[0021] The lug plate a404 on the operating platform 4 is connected to the U-shaped lug plate 403 welded to the upper surface of the frame 1 via a pin a402. This connection method allows the operating platform 4 to be tilted up and down around the pin a402. When needed, the operating platform 4 is tilted downwards to a horizontal position. At this time, the pre-deployed support arm assembly 7 moves under the platform 401, providing reliable support for the operating platform 4 and facilitating the operator to stand and perform maintenance work, as shown in the attached figure. Figure 1 As shown.

[0022] The left column assembly 501 and the right column assembly 501 are fixedly mounted on the frame 1 and located on both sides of the operating platform 4, respectively. The two column assemblies 501 are symmetrical in structure. The left column assembly 501 and the right column assembly 501 are provided with limiting devices 502 for fixing when the operating platform 4 is folded to a vertical position.

[0023] To further ensure the stability of the outrigger 701 in the retracted state, as shown in the attached document... Figure 2 and attached Figure 5 As shown, the support arm 701 is provided with one or more holes. When the support arm 701 is rotated to be parallel to the side of the frame 1, the operator can use the pin a6 to pass through the hole and the corresponding hole on the frame 1 to securely lock the support arm 701 in the retracted position and prevent it from shaking due to vibration during vehicle operation.

[0024] In another technical solution, the limiting device 502 is a sliding pin or latch structure. When the operating platform 4 is flipped to the vertical position, the limiting device 502 is slidably engaged with the corresponding part on the operating platform 4. When the operating platform 4 is finished using and flipped upwards to the vertical (folded) state, the operator can slide the limiting device 502 to engage with the corresponding part on the side of the operating platform 4, thereby firmly locking the operating platform 4 in the folded position and preventing it from unfolding on its own, as shown in the attached figure. Figure 2 and attached Figure 3As shown. In one embodiment of this solution, the limiting device 502 includes a slider slidably disposed on the column 501 and a compression spring. The slider has a downward movement tendency under the action of the spring force. The side of the operating platform 4 is provided with a locking slot adapted to the slider. When the operating platform 4 is flipped to the vertical position, the slider automatically slides into the locking slot under the push of the compression spring to achieve locking.

[0025] In another technical solution, a guardrail 3 is also included. The upright of the guardrail 3 is inserted into the bushing at the other end of the support arm 701. This insertion connection allows the guardrail 3 and the support arm 701 to rotate freely. When the support arm 701 is extended, the guardrail 3 moves with the support arm 701 and adjusts to be upright on the side of the platform 401, providing a safety protection function. When the support arm 701 is retracted, the guardrail 3 also rests against the frame 1.

[0026] In another technical solution, a protective door 507 is also provided on both the left column 501 assembly 5 and the right column 501 assembly 2. The ear plate on the protective door 507 is connected to the ear plate c505 welded to the column 501 via a pin b506, allowing the protective door 507 to rotate around the pin b506 to open and close. When the protective door 507 is closed, another ear plate on the protective door 507 corresponds to the ear plate b503 on the column 501, and can be fixed by using a pin b504 passing through the ear plate on the protective door 507 and the ear plate b503 on the column 501, thereby forming a complete safety enclosure on the opening side of the operating platform 4, further ensuring the safety of the operators.

[0027] The working process of this utility model is as follows: Deployment process: First, remove the pin a6 of the fixed support arm 701 and rotate the support arm 701 horizontally to deploy it; then, release the limiting device 502, flip the vertical operating platform 4 downward to the horizontal, and support it with the deployed support arm 701. At the same time, the guardrail 3 is in place, and the protective door 507 is closed and inserted to form a safe working area.

[0028] Retraction process: The operator leaves platform 401 and opens protective door 507; the operating platform 4 is flipped upward to a vertical position, and the sliding limit device 502 is used to lock and fix it; then, the support arm 701 is rotated horizontally to be close to the side of the frame 1, and the pin a6 is inserted to fix it. The entire device is then compactly retracted within the frame 1.

[0029] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
