Description

Technical Field

[0001] This utility model relates to the field of gearbox cover disassembly technology, and in particular to a disassembly device for a manual ball valve gearbox cover in a natural gas station. Background Technology

[0002] In gas transmission and distribution systems, manual ball valves are key devices for controlling the on / off state and flow rate of pipeline media. Their gearbox covers are fixed with bolts and sealed to the valve body. Due to the complex environment of gas stations (such as high pressure, flammable and explosive media, and corrosive media), ball valves require regular maintenance or emergency repairs, and disassembling the gearbox cover is a crucial step in the maintenance process. The gearbox cover bolts are typically symmetrically distributed and have high preload, requiring multiple people to disassemble manually, which is time-consuming, especially in confined spaces or at heights.

[0003] Currently, there are various specifications of gearboxes in gas stations. Traditional disassembly tools (such as ordinary wrenches and pry bars) are incompatible with the irregular structure of the gearbox covers, which can easily lead to low disassembly efficiency and even damage to the sealing surface or bolt threads, affecting the reusability of the equipment. Therefore, there is an urgent need for a manual ball valve gearbox cover disassembly tool for gas stations to improve operational safety and reduce maintenance costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a manual ball valve gearbox cover disassembly device for natural gas stations, which aims to improve the inconvenience of opening and maintaining the ball valve gearbox.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a disassembly device for a manual ball valve gearbox cover of a natural gas station, comprising a force-bearing rod, a limit groove inside the force-bearing rod, a movable rod slidably connected to the outer wall of the force-bearing rod, a top rod through hole inside the force-bearing rod, a top rod inside the top rod through hole, the top rod being threadedly connected to the inside of the force-bearing rod through the top rod through hole, and a top rod sleeve fixedly connected to the bottom of the top rod.

[0006] As a further description of the above technical solution:

[0007] The bottom of the movable rod is threaded with a locking screw, and an adjusting rod is rotatably connected to the outer wall of the locking screw.

[0008] As a further description of the above technical solution:

[0009] The bottom of the adjusting rod is threadedly connected to a force-bearing screw, and the bottom of the force-bearing screw is fixedly connected to a force-bearing claw.

[0010] As a further description of the above technical solution:

[0011] The top of the movable rod is slidably connected to a limiting device, which passes through the limiting groove.

[0012] As a further description of the above technical solution:

[0013] The movable rod is limited on the outer wall of the force-bearing rod by a limiting device.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the position of the moving rod on the force-bearing rod of the gearbox cover size adjustment rod is adjusted, and the angle of the adjusting rod at the lower end of the moving rod is finely adjusted. Then, the force-bearing claw head is screwed into the internal thread hole at the lower end of the adjusting rod through the force-bearing screw and inserted into both ends of the gearbox cover. This causes the push rod sleeve to push the shaft under the action of leverage, thereby realizing the quick opening of the gearbox cover. This achieves the effect of facilitating the disassembly of the ball valve gearbox cover, solving the problem of inconvenience when the ball valve gearbox needs to be opened for maintenance, and improving the convenience of ball valve gearbox maintenance.

[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3This utility model provides an embodiment of a disassembly device for a manual ball valve gearbox cover in a natural gas station. The device includes a force-bearing rod 1, which serves as the main support for the overall disassembly structure, bearing the connection and force transmission of various components. A limiting groove 2 is formed inside the force-bearing rod 1, providing a movement trajectory for a limiting device 9 to ensure the moving rod 5 is accurately positioned within a set range. The moving rod 5 is slidably connected to the outer wall of the force-bearing rod 1. The moving rod 5 is used to adjust the lateral position on the force-bearing rod 1 according to the width of the gearbox cover, adapting to different models. The gearbox structure includes a push rod through hole 10 inside the force-bearing rod 1. This through hole 10 serves as a mounting hole, ensuring the push rod 3 is stably guided and transmits force in the vertical direction. The push rod 3 is housed inside the through hole 10, applying a lifting force. It drives the push rod sleeve 4 via rotation to achieve upward axial force transmission. The push rod 3 is threaded into the force-bearing rod 1 through the through hole 10. This threaded connection facilitates the vertical adjustment of the push rod 3 and the transmission of torque. The push rod sleeve 4 is fixedly connected to the bottom of the push rod 3, and the push rod sleeve 4 is centered with the gearbox cover. The shafts are in corresponding contact, directly acting on the lifting of the cover during rotation. A locking screw 7 is threadedly connected to the bottom of the moving rod 5, used to fix the adjusting rod 6 and prevent positional displacement due to vibration during operation. The adjusting rod 6 is rotatably connected to the outer wall of the locking screw 7, allowing for fine adjustment in the parallel angle direction to control the position and angle of the force-bearing claw head 8. A force-bearing screw 11 is threadedly connected to the bottom of the adjusting rod 6, allowing for vertical height adjustment by adjusting the screw-in depth. The bottom of the force-bearing screw 11 is fixed. A force-bearing claw 8 is connected and inserted into the locking point on the side of the gearbox cover. Under the drive of the top rod 3, it plays a role in pulling open. A limit device 9 is slidably connected to the top of the moving rod 5. The limit device 9 is used to limit the lateral movement range of the moving rod 5 to ensure that it does not deviate after positioning. The limit device 9 passes through the limit groove 2. By cooperating with the limit groove 2, it realizes adjustable positioning and anti-displacement functions. The moving rod 5 is limited by the limit device 9 on the outer wall of the force-bearing rod 1, thereby improving the structural stability and positioning accuracy of the device during operation.

[0023] Working principle: When using this manual ball valve gearbox cover disassembly device for natural gas stations, adjust the position of the moving rod 5 on the force-bearing rod 1 according to the size of the manual ball valve gearbox cover. Use the limiting device 9 to accurately position it on the limiting groove 2. Fine adjust the lower end of the moving rod 5 to the adjusting rod 6 connected by the locking screw 7 to adjust its angle in the parallel direction. Screw the force claw 8 into the internal threaded hole at the lower end of the adjusting rod 6 through the vertically connected force screw 11. While adjusting the parallel angle using the adjusting rod 6, insert the force claw 8 into both ends of the gearbox cover. Rotate the top rod 3 on the force-bearing rod 1, which is threaded to the top rod through hole 10. This causes the top rod sleeve 4, which is threaded to the top rod 3, to push the shaft under the action of leverage force, quickly opening the gearbox cover upwards.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
