Description

Technical Field

[0001] The invention relates to the technical field of safety protection of petroleum equipment, in particular to an active braking device for a refueling well joint which can prevent movement. Background Art

[0002] The refueling well connector is a key component in the refueling system of a gas station. It is mainly used to connect the underground oil pipeline and the refueling gun. Its function is to safely and efficiently transport the fuel in the underground oil storage tank to the refueling gun, thereby providing fuel filling services for vehicles and other equipment. The refueling well connector usually has one end tightly connected to the underground oil pipeline. This part of the connection structure needs to have good sealing properties to prevent fuel leakage. Generally, special sealing materials and fastening devices such as sealing gaskets, threaded connections or flange connections are used to ensure that the fuel can be stably transmitted from the underground pipeline under long-term pressure.

[0003] In the prior art, after the three-inch refueling connector is moved to an ideal position, one person is required to hold the handle while another person rotates and removes the threaded rod on the brake rod, pulls the brake rod downward to make it contact with the ground, and then rotates the threaded rod again to fix the brake rod. However, the operation is complicated and cumbersome, requiring the cooperation of two people, one person holding the handle while the other person performs multiple steps such as rotating and removing the threaded rod on the brake rod, pulling out and inserting the brake pull, and rotating the threaded rod again to fix it. This not only wastes manpower, but also takes a long time to operate and has low braking efficiency. Summary of the invention

[0004] The object of the present invention is to provide an active braking device for a refueling well joint that prevents movement, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides an active braking device for a refueling well joint that prevents movement, comprising a joint body, a mounting sleeve rod, and a support rod, the support rod, the interior of the mounting sleeve rod being slidably connected with the support rod, the top of the support rod extending a round block that is adapted to the mounting cavity inside the mounting sleeve rod; a reset spring, fixedly mounted between the top round block of the support rod and the inner top wall of the mounting sleeve rod; a frustum, fixedly mounted on the circumferential outer wall of the support rod, and its shape is set to be wide at the top and narrow at the bottom; a mounting frame, fixedly mounted on the circumferential outer wall of the mounting sleeve rod, a trapezoidal block being slidably connected to the mounting frame, the head of the trapezoidal block extending to the interior of the mounting sleeve rod; the trapezoidal block, whose cross section is set to be a right-angled trapezoid, and whose shape is set to be narrow at the top and wide at the bottom; a tension spring, fixedly mounted between the tail of the trapezoidal block and the inner wall of the mounting frame; a pull rope, a plurality of pull ropes are fixedly mounted on the top of the round block, and a pull block is fixedly mounted on the top of the mounting sleeve rod.

[0006] Furthermore, a mounting frame is fixedly mounted on the outer wall of the joint body, a fixing block is fixedly mounted on the top of the mounting frame, and a square opening is formed on the top of the fixing block.

[0007] Furthermore, the top fixed mounting plate of the mounting sleeve rod has a handle, a threaded rod is arranged on the square opening, and a nut is threadedly connected to the outer wall of the threaded rod.

[0008] Furthermore, the diameter of the mounting sleeve rod is greater than the width of the square through-hole, and the nut is greater than the cross-section of the square through-hole.

[0009] Furthermore, a support block is fixedly mounted on the bottom end of the support rod, and the support block is made of steel.

[0010] Furthermore, a pull rod is fixedly installed at the tail of the trapezoidal block, a circular limit block is fixedly installed at one end of the pull rod away from the trapezoidal block, and a pull ring is fixedly installed on one side of the circular limit block.

[0011] Furthermore, the area of ​​the tail of the trapezoidal block is larger than the circular opening between the pull rod and the installation frame, and a square limiting block is fixedly installed on the bottom of the trapezoidal block.

[0012] Furthermore, a guide telescopic rod is fixedly installed between the circular block on the top of the support rod and the inner top wall of the mounting sleeve rod, and a universal wheel is installed on the joint body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, during operation, the staff tightly grasps the pull block and the handle at the top of the pull rope, and the pull block pulls the support rod by the pull rope, while the handle pulls the connector body to the desired position. After releasing the pull block, the reset spring pushes the support rod to move downward, and the outer wall of the truncated table contacts and slides with the inclined surface of the trapezoidal block until the truncated table slides below the trapezoidal block. The two are tightly fitted and contacted to form a stable clamping structure, which prevents the support rod from moving and ensures the stability of the brake device. Loosening the pull block and the handle at the top of the pull rope can realize autonomous braking, and realize the flexible and efficient braking function of the connector body.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 6 , the present invention provides a technical solution:

[0025] See also Figure 1-Figure 6As shown, an active braking device for a refueling well joint to prevent movement includes a joint body 1, a mounting sleeve rod 7, and a support rod 8. The support rod 8 is slidably connected to the interior of the mounting sleeve rod 7, and a round block adapted to the mounting cavity inside the mounting sleeve rod 7 extends from the top of the support rod 8; a reset spring 9 is fixedly installed between the top round block of the support rod 8 and the inner top wall of the mounting sleeve rod 7; a frustum 10 is fixedly installed on the circumferential outer wall of the support rod 8, and its shape is set to be wide at the top and narrow at the bottom; a mounting frame 12 is fixedly installed on the circumferential outer wall of the mounting sleeve rod 7, and a trapezoidal block 11 is slidably connected to the mounting frame 12, and the head of the trapezoidal block 11 extends to the interior of the mounting sleeve rod 7; the trapezoidal block 11 has a cross-section set to a right-angle trapezoid, and its shape is set to be narrow at the top and wide at the bottom; a tension spring 14 is fixedly installed between the tail of the trapezoidal block 11 and the inner wall of the mounting frame 12; a pull rope 17, a plurality of pull ropes 17 are fixedly installed on the top of the round block, and a pull block is fixedly installed on the top of the mounting sleeve rod 7

[0026] During the operation, the staff first holds the pull block and the handle 4 at the top of the pull rope 17. At this time, the pull block pulls the support rod 8 upward with the help of the connection of the pull rope 17. At the same time, the connector body 1 can be flexibly pulled to any desired position with the help of the handle 4. Then, when the staff releases the pull block, the reset spring 9 pushes the support rod 8 downward with its own elastic force. During this period, the outer wall of the truncated cone 10 gradually comes into contact with the inclined surface of the trapezoidal block 11 and slides relative to each other until the truncated cone 10 slides smoothly to the bottom of the trapezoidal block 11. At this time, the bottom of the trapezoidal block 11 fits tightly with the top of the truncated cone 10 and conflicts with each other, thereby building a stable clamping structure. This clamping effect can effectively prevent the support rod 8 from being displaced toward the mounting sleeve rod 7 due to external force when the support block 16 at the bottom end of the support rod 8 is tightly against the ground, thereby effectively ensuring the stability of the entire braking device. At the same time, the pull block on the top of the pull rope 17 and the handle 4 can be loosened to achieve autonomous braking, ultimately realizing the flexible and efficient braking function of the joint body 1.

[0027] See also Figure 1 A mounting frame 2 is fixedly mounted on the outer wall of the joint body 1, a fixing block 3 is fixedly mounted on the top of the mounting frame 2, and a square opening is opened on the top of the fixing block 3.

[0028] The fixing block 3 on the top of the mounting frame 2 and the square opening provided therein further facilitate the installation of other components. The regular shape of the square opening provides a clear positioning and connection mode for the installation of other components.

[0029] In the active brake device for the refueling well joint to prevent movement, the mounting frame 2 fixedly mounted on the outer wall of the joint body 1 provides a stable mounting base for other components. Just like the frame structure of a building, the mounting frame 2 tightly connects the joint body 1 with the subsequently installed components, making the entire device more stable during operation.

[0030] See also Figure 1 The top fixed mounting plate of the mounting sleeve rod 7 has a handle 4, a threaded rod 6 is arranged on the square opening, and a nut 5 is threadedly connected to the outer wall of the threaded rod 6.

[0031] By using the cooperation between the threaded rod 6 and the nut 5, the installation sleeve rod 7 can also be accurately positioned on the square opening. During the installation process, the operator can fine-tune the screwing depth of the nut 5 on the threaded rod 6 to accurately adjust the height, horizontality and other position parameters of the installation sleeve rod 7, so that the components in the installation sleeve rod 7 and the joint body 1 and other related components maintain the best relative position relationship, thereby ensuring the normal performance of various functions of the device. For example, for the sensor in the installation sleeve rod 7, accurate positioning can ensure that it can accurately detect the motion state of the joint body 1, providing reliable data support for the precise control of the active brake device.

[0032] See also Figure 5 The diameter of the mounting sleeve rod 7 is larger than the width of the square opening, and the nut 5 is larger than the cross-section of the square opening.

[0033] The diameter of the mounting sleeve 7 is larger than the width of the square opening, and this design can effectively prevent the mounting sleeve 7 from accidentally falling off the square opening. Just like a stopper is slightly larger than the mouth of a bottle, this interference design allows the mounting sleeve 7 to be firmly stuck on the square opening after installation. For example, during the operation of the refueling well joint, it may be subjected to forces in various directions, such as the pulling force generated by the movement of the refueling vehicle or the impact force generated by the vibration of the refueling equipment itself, and the mounting sleeve 7 with a larger diameter can resist these external forces and ensure that its position is relatively fixed, thereby providing a basis for the stable operation of the entire device.

[0034] The nut 5 is larger than the cross section of the square opening. When the nut 5 is tightened on the threaded rod 6, it can limit the installation sleeve rod 7 from above. This is like putting a "hat" on the installation sleeve rod 7 to prevent it from slipping out of the square opening. At the same time, this design also increases the tightness of the connection between the installation sleeve rod 7 and the square opening, so that the connection between them can withstand a larger load, further improving the stability of the device in a complex working environment.

[0035] See also Figure 1-2 A support block 16 is fixedly installed at the bottom end of the support rod 8, and the material of the support block 16 is steel.

[0036] Steel is a material with high strength. The support block 16 is made of steel and can provide strong support for the entire device. When the active brake device works to prevent the refueling well joint from moving, the support block 16 needs to withstand the joint and the external forces that may be applied to the joint. The high yield strength and tensile strength characteristics of steel enable it to effectively resist these forces and prevent the support rod 8 from excessively sinking or deforming, thereby ensuring that the device can stably fix the joint in the desired position.

[0037] Due to the high rigidity of steel, the support block 16 can increase the stability of the bottom of the device. In a working environment such as a refueling well, it may be disturbed by factors such as vehicle driving and equipment vibration. The steel support block 16 can act like a solid foundation to firmly fix the support rod 8 on the ground, reduce the shaking and displacement of the entire device, and ensure that the active brake device can work reliably under various complex working conditions.

[0038] See also Figure 5 A pull rod 13 is fixedly installed at the tail of the trapezoidal block 11, a circular limit block is fixedly installed at one end of the pull rod 13 away from the trapezoidal block 11, and a pull ring is fixedly installed on one side of the circular limit block.

[0039] During the operation of the device, the engagement state of the trapezoidal block 11 and the truncated table 10 can be accurately controlled by the pull ring and the pull rod 13. For example, when the engagement needs to be released to perform some special operations such as moving or adjusting the equipment, the pull ring can be pulled to disengage the trapezoidal block 11 from the truncated table 10; and during normal operation, the trapezoidal block 11 can be accurately engaged with the truncated table 10, achieving stable position limiting of the support rod 8, and improving the control accuracy and reliability of the active braking device.

[0040] The setting of the pull ring provides a convenient operation point for the staff, so that they can directly apply force with their hands without the help of other complicated tools. The trapezoidal block 11 can be easily controlled through the pull rod 13, thereby completing related operations more efficiently.

[0041] The pull rod 13 and the circular limit block effectively restrain and support the trapezoidal block 11, preventing the trapezoidal block 11 from excessive displacement or shaking due to external forces during operation, thereby enhancing the stability of the entire structure and helping to maintain the reliability and safety of the brake device.

[0042] See also Figure 5 The area of ​​the tail of the trapezoidal block 11 is larger than the circular opening between the pull rod 13 and the mounting frame 12 , and a square limit block 15 is fixedly mounted on the bottom of the trapezoidal block 11 .

[0043] The area of ​​the tail of the trapezoidal block 11 is larger than the circular opening between the pull rod 13 and the mounting frame 12. This design can effectively prevent the trapezoidal block 11 from falling off from the circular opening. Just like the large head of a stopper stuck in the mouth of a bottle, this structure of the trapezoidal block 11 can ensure that it will not easily fall out of the mounting frame 12 during the operation of the device even if it is pulled by a large external force, such as in a vibration environment or when the pull rod 13 is misoperated, thereby ensuring the integrity of the device structure and the stability of the connection between the various components.

[0044] The square stopper 15 fixedly installed at the bottom provides additional support and positioning functions for the trapezoidal block 11. When the trapezoidal block 11 slides in the mounting frame 12 or is in the working position, the square stopper 15 can contact the inner wall or other internal structure of the mounting frame 12 to limit the excessive movement of the trapezoidal block 11 and ensure that it functions in the correct position.

[0045] See also Figure 4 A guide telescopic rod is fixedly installed between the circular block at the top of the support rod 8 and the inner top wall of the mounting sleeve rod 7, and a universal wheel is installed on the joint body 1.

[0046] When subjected to external forces, the guide telescopic rod helps to enhance the structural stability of the entire device. Whether the refueling well joint is subjected to horizontal impact force or various forces generated by equipment vibration, the guide telescopic rod can cooperate with the support rod 8 and the mounting sleeve rod 7 to reasonably disperse and withstand these external forces. For example, when a large external force attempts to bend or deform the support rod 8, the guide telescopic rod can provide additional support and resistance to prevent the device structure from being damaged due to uneven force, ensuring that the device can still maintain a stable working state under complex working conditions.

[0047] The installation of universal wheels enables the joint body 1 to be moved to the ideal position more flexibly, and the staff can easily push the joint body 1 without laborious carrying, which greatly improves work efficiency. Especially in the case where the joint position needs to be adjusted frequently, the advantage is more obvious.

[0048] Working principle: During the operation, the staff first holds the pull block and the handle 4 at the top of the pull rope 17. At this time, the pull block pulls the support rod 8 upward with the help of the connection of the pull rope 17. At the same time, the joint body 1 can be flexibly pulled to any desired position with the help of the handle 4. Then, when the staff releases the pull block, the reset spring 9 pushes the support rod 8 downward by its own elastic force. During this period, the outer wall of the truncated table 10 gradually comes into contact with the inclined surface of the trapezoidal block 11 and slides relative to each other until the truncated table 10 slides smoothly to the bottom of the trapezoidal block 11. At this time, the bottom of the trapezoidal block 11 fits tightly with the top of the truncated table 10 and conflicts with each other, thereby constructing a stable clamping structure. This clamping effect can effectively prevent the support block 16 at the bottom of the support rod 8 from being displaced toward the mounting sleeve rod 7 due to external force when it is tightly against the ground, thereby effectively ensuring the stability of the entire brake device and finally realizing the efficient braking function of the joint body 1.

[0049] During the operation of the device, the engagement state of the trapezoidal block 11 and the truncated table 10 can be accurately controlled by the pull ring and the pull rod 13. For example, when the engagement needs to be released to perform some special operations such as moving or adjusting the equipment, the pull ring can be pulled to disengage the trapezoidal block 11 from the truncated table 10; and during normal operation, the trapezoidal block 11 can be accurately engaged with the truncated table 10, achieving stable position limiting of the support rod 8, and improving the control accuracy and reliability of the active braking device.
