Description

Technical Field

[0001] This invention relates to the field of safety equipment technology for oilfield well workover operations, specifically a rapid fixing device for a balanced guardrail. Background Technology

[0002] Safety railings are essential safety protection facilities on work platforms in oilfield well repair and construction, used to prevent workers from accidentally falling and ensure personal safety. To meet the needs of transportation, installation, and dismantling, existing railings are usually designed as detachable structures. Balanced railing quick-fix devices are a common fixing method, using a balancing principle and clamping mechanism to secure the railing, improving the ease of installation and dismantling, and to a certain extent enhancing the stability and safety of the railing.

[0003] Existing balanced guardrail fixing devices primarily achieve guardrail fixation through a simple insertion structure. Specifically, guardrail posts are inserted into fixing sleeves on a platform, and a limiting structure or manual clamping mechanism prevents the posts from swaying. This type of device has the following advantages: relatively simple structure, low processing cost, suitable for mass production; relatively convenient installation and disassembly, meeting general usage needs; and through certain limiting designs, initial guardrail fixation can be completed in a short time, ensuring basic safety performance.

[0004] However, existing balanced guardrail fixing devices still have the following shortcomings: Insufficient clamping stability: Existing devices mostly use the insertion sleeve fixing method, and the limiting structure is relatively simple. There is a gap between the guardrail post and the sleeve, which makes the guardrail easy to shake after installation, affecting the safety of operation. Cumbersome operation: Some existing devices rely on manual clamping or additional tools to assist in installation and disassembly, which is complicated to operate, reduces work efficiency, and makes it difficult to meet the needs of operation scenarios that require frequent installation and disassembly. Poor impact and vibration resistance: The fixing device is prone to loosening when faced with external impact and vibration, affecting the fixing effect of the guardrail and the safety of the overall device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a balanced guardrail quick-fixing device, which solves the problems of poor clamping stability, cumbersome operation, and insufficient impact and vibration resistance of existing guardrail fixing devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a balanced guardrail quick-fixing device, comprising: The operating platform provides operating space for well workover operations in the oilfield and provides a stable support foundation for the entire unit; Guardrails are installed on the upper side of the operating platform to prevent workers from falling off the platform and ensure personal safety at the work site. A balanced locking mechanism is installed between the operating platform and the guardrail to achieve automatic clamping and release of the guardrail. At the same time, the balanced locking mechanism can clamp the guardrail by squeezing to form a clamping force, making the guardrail stable and not wobbling.

[0007] Preferably, the balanced locking mechanism includes a fixed base, which is installed on the upper side of the operating platform. The guardrail is slidably connected to the middle of the fixed base. Two ear plates are fixedly connected to the outer side of the fixed base. A pin is slidably connected to the middle of the two ear plates. A balanced locking block is sleeved on the outer periphery of the pin. The balanced locking block is rotatably connected between the two ear plates. The pin is located below the center of gravity of the balanced locking block.

[0008] Preferably, the outer side of the fixing seat has a U-shaped notch one and a U-shaped notch two sequentially formed from top to bottom, and the balance locking block is slidably connected to the middle of the U-shaped notch one and the U-shaped notch two.

[0009] Preferably, the balance locking block and the two ear plates are provided with connecting holes in the middle, and the pin is slidably connected to the middle of the connecting holes.

[0010] Preferably, the balancing locking block has a positioning arc surface one and a positioning arc surface two arranged sequentially from top to bottom on the side near the fixed seat, which are used to achieve automatic clamping when the guardrail is inserted.

[0011] Preferably, the mounting base includes, but is not limited to, welding and fixing to the operating platform to provide stable support.

[0012] This invention also provides a method for using a balanced guardrail quick-fixing device, comprising the following steps: Install the balanced locking mechanism on the operating platform; Insert the guardrail into the fixing seat and activate the balance locking block to clamp and fix it; The guardrail can be removed by lifting it upwards.

[0013] Preferably, the installation steps include: The mounting bracket is welded to the predetermined position above the operating platform; Pass the pin through the connecting hole between the fixed base and the balance locking block to allow the balance locking block to rotate freely.

[0014] Preferably, the clamping and fixing step includes: Insert the guardrail into the operating platform; The downward pressure of the guardrail causes the balance locking block to open outwards, causing the bottom positioning arc surface one to clamp the guardrail tightly against the inner wall of the fixing seat.

[0015] Preferably, the disassembly step includes: Lift the guardrail upwards so that the lower end of the guardrail is disengaged from the positioning arc surface of the balance locking block; The balance locking block rotates clockwise to release the clamping state of the guardrail.

[0016] This invention provides a quick-fixing device for balanced guardrails. It has the following beneficial effects: 1. This invention achieves automatic clamping and rapid release of guardrail posts by using the upper and lower positioning arc surface design of the balancing locking block combined with the rotation fulcrum of the pin. The installation and disassembly of the guardrail requires no additional tools, making operation simple, improving work efficiency, and suitable for scenarios requiring frequent installation and disassembly.

[0017] 2. This invention uses multi-point contact clamping to clamp the guardrail posts, forming a stable supporting force and preventing the posts from shaking. The welding and fixing of the fixed base to the operating platform improves the overall impact and vibration resistance of the device, ensuring the stability and safety of the guardrail during operation.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides a quick-fixing device for a balanced guardrail, comprising: Operating platform 1 is used to provide operating space for oilfield well workover operations and to provide a stable support foundation for the entire unit. As a basic structure, operating platform 1 provides a stable installation carrier, ensuring the reliability and structural safety of the rotor and adapting to complex working conditions. Guardrail 2 is installed on the upper side of the operating platform 1 to prevent workers from falling off the operating platform 1 and to ensure personal safety at the work site. Guardrail 2 has a simple structure, which can improve the safety of the working environment, prevent accidental falls, and reduce safety risks. The balanced locking mechanism 30 is installed between the operating platform 1 and the guardrail 2 to realize the automatic clamping and release of the guardrail 2. At the same time, the balanced locking mechanism 30 can clamp the guardrail 2 by squeezing to form a clamping force, making the guardrail 2 stable and not shaking. The balanced locking mechanism 30 automatically realizes the clamping and release of the guardrail 2 through the balance principle. The installation and disassembly process is quick and simple. At the same time, the guardrail 2 is firmly fixed through multi-point contact, which improves the stability of the guardrail 2.

[0022] Please see the appendix Figure 1 - Appendix Figure 7 In a preferred embodiment of the present invention, the balanced locking mechanism 30 includes a fixed base 301, which is mounted on the upper side of the operating platform 1. The guardrail 2 is slidably connected to the middle of the fixed base 301. Two ear plates 302 are fixedly connected to the outer side of the fixed base 301. A pin 304 is slidably connected to the middle of the two ear plates 302. A balanced locking block 303 is sleeved on the outer periphery of the pin 304. The fixed base 301 is used to provide support and sliding fit space between the guardrail 2 and the balanced locking block 303. This allows the guardrail 2 to be inserted smoothly, while the fixing seat 301 and the balance locking block 303 form a sliding contact. The balance locking block 303 is rotatably connected between the two ear plates 302, and the pin 304 is located below the center of gravity of the balance locking block 303. The ear plates 302 and the pin 304 form a stable rotation fulcrum, allowing the balance locking block 303 to rotate freely around the pin 304. This ensures the automatic clamping function of the balance locking block 303 during the installation of the guardrail 2, improving the ease of operation and stability of the device.

[0023] Please see the appendix Figure 3 In a preferred embodiment of the present invention, the outer side of the fixing base 301 is provided with U-shaped notch 1 4 and U-shaped notch 2 5 from top to bottom. The balance locking block 303 is slidably connected to the middle of U-shaped notch 1 4 and U-shaped notch 2 5. By setting U-shaped notch 1 4 and U-shaped notch 2 5, the up and down sliding of the balance locking block 303 is effectively guided, so that it can rotate smoothly and automatically clamp when the guardrail 2 is inserted, thereby improving the stability of the structure and the reliability of clamping.

[0024] Please see the appendix Figure 1 - Appendix Figure 7 In a preferred embodiment of the present invention, a connecting hole 6 is provided in the middle of both the balance locking block 303 and the two ear plates 302. The pin 304 is slidably connected in the middle of the connecting hole 6. By providing the connecting hole 6 in the middle of the balance locking block 303 and the ear plates 302, a stable mounting fulcrum for the pin 304 is formed, which effectively ensures the smooth rotation of the balance locking block 303, improves the structural stability and reliability of the device, and ensures the effective transmission of the insertion force of the guardrail 2, thereby realizing automatic clamping and release, and improving operating efficiency and safety.

[0025] Please see the appendix Figure 4 In a preferred embodiment of the present invention, the balancing locking block 303 is provided with a positioning arc surface 7 and a positioning arc surface 8 from top to bottom on the side near the fixing base 301. These are used to achieve automatic clamping when the guardrail 2 is inserted. The positioning arc surface 7 and the positioning arc surface 8 work together to enable the balancing locking block 303 to automatically respond to the insertion force of the guardrail 2, forming a stable clamping effect, achieving quick installation, simple operation, and stable and reliable operation. At the same time, the design of the positioning arc surface 7 and the positioning arc surface 8 utilizes the principle of mechanical balance to achieve automatic clamping of the guardrail 2. The multi-point contact support effectively improves the stability of the guardrail 2, avoids shaking, and ensures operational safety.

[0026] Please see the appendix Figure 1 - Appendix Figure 3 In a preferred embodiment of the present invention, the fixing base 301 includes, but is not limited to, welding and fixing to the operating platform 1 to provide stable support.
