Description

Technical Field

[0001] This application relates to the field of gas cylinder vehicle support technology, and in particular to a novel gas cylinder vehicle. Background Technology

[0002] Gas-insulated metal-enclosed switchgear is widely used in power systems due to its advantages such as small footprint, high reliability, and low maintenance workload. During the installation and maintenance of gas-insulated metal-enclosed switchgear, the gas chamber is often filled and replenished with gas, requiring the use of a large number of gas cylinder trolleys to transport sulfur hexafluoride cylinders and nitrogen cylinders.

[0003] Traditional vehicle-mounted gas cylinder support frames include: spaced-apart saddle brackets, with a connecting plate between two saddle brackets. The connecting plate is arc-shaped relative to the gas cylinder, supporting it. Steel straps for securing the gas cylinder are mounted on the two saddle brackets, with both ends fixed to the saddle brackets. Therefore, the gas cylinder can be secured by adjusting the steel straps. Furthermore, to ensure the connection strength between the saddle brackets and the vehicle body and to prevent the gas cylinder from shaking or falling off during transportation, existing saddle brackets typically use a rigid connection method when fixing them to the vehicle body.

[0004] Rigid connections typically include welding or multiple sets of bolts. Welding makes the saddle bracket integrated with the vehicle body, preventing disassembly and increasing transportation and storage costs. For example, when the gas cylinder vehicle is not in use, it is inconvenient to separate the saddle bracket from the tie rod to reduce the overall volume and facilitate warehousing or transportation. Bolt fixing, on the other hand, requires auxiliary tools for multiple tightening and loosening operations, which are cumbersome and time-consuming. Furthermore, under long-term vibration, the bolts are prone to loosening or corrosion, making later maintenance and disassembly difficult and failing to meet users' needs for quick installation and removal of the saddle bracket. Summary of the Invention

[0012] In some embodiments, a sector-shaped groove is provided on the other side of the first limiting plate, and a sector-shaped portion is provided on the second limiting plate. The sector-shaped portion is engaged with the sector-shaped groove. A locking component is provided between the first limiting plate and the second limiting plate.

Detailed Implementation

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

[0021] This application provides a novel gas cylinder vehicle that solves the problem in related technologies where the saddle bracket is mainly fixed by welding or multiple sets of bolts during installation, making it inconvenient to separate the saddle bracket from the tie rod.

[0022] Reference Figure 1-7 A new type of gas cylinder vehicle, comprising a gas cylinder vehicle body 1, a saddle support 3, and an installation and removal mechanism 5. The gas cylinder cart body 1 is equipped with a pull rod 2, which is made of a separate adjustable type and includes two parts: a lower rod and an upper rod. There are two lower rods, which are symmetrically installed on one side of the gas cylinder cart body 1. The upper rod is U-shaped and is fitted onto the two lower rods. The upper rod and the lower rod are connected by a spring pin. A mounting block 30 is fixed on one side of the saddle bracket 3, and a pull strap 31 is connected to the other end. The pull strap 31 is wrapped to form a ring, and the gas cylinder is placed in the middle of the pull strap 31 and fixed. The tension of the pull strap 31 is adjustable, and the tension can be adjusted by means of, but not limited to, adjusting buckles. A fixing block 4 is fixedly fitted onto the pull rod 2, and the fixing block 4 has a slot 40. The mounting block 30 is snapped into the slot 40. The installation and removal mechanism 5 includes a docking component 50 and a snap-fit ​​component 51. The docking component 50 is located on the mounting block 30, and the snap-fit ​​component 51 is located on the fixing block 4. The docking component 50 and the snap-fit ​​component 51 cooperate to detachably connect the saddle bracket 3 and the fixing block 4.

[0023] By matching the dimensions of the mounting block 30 on one side of the saddle bracket 3 with the slot 40 on the fixing block 4, the mounting block 30 is first inserted into the slot 40 to complete the pre-installation, achieving the initial physical connection and positional limitation between the bracket and the vehicle body, ensuring the accuracy of the docking and preventing initial misalignment. Subsequently, the docking component 50 on the mounting block 30 and the snap-fit ​​component 51 on the fixing block 4 lock together to complete the final rigid fixation, forming a reliable mechanical lock. The synergistic effect of the docking component 50 and the snap-fit ​​component 51 enables a quick and detachable connection between the saddle bracket 3 and the vehicle body. This design uses mechanical locking instead of threaded fastening, which not only avoids the non-removability caused by welding and solves the problem of large space occupation when not in use, but also overcomes the defects of bolted connections, such as easy loosening and corrosion under vibration and cumbersome disassembly and assembly. Users can complete the installation and separation without auxiliary tools, which is convenient for warehousing, storage and transportation, significantly improving operation and maintenance efficiency and reducing management costs.

[0024] In this application, a slot 300 is provided on the mounting block 30, with the slot opening facing the bottom of the mounting block 30. The mounting block 30 is divided by the slot 300 to form a mounting ring 32 and a reinforcing block 33. The mounting ring 32 is snapped into the slot 40, and the reinforcing block 33 is located on the outside of the slot 40. During actual installation, both the slot 40 and the slot 300 penetrate the tie rod 2, separating the upper and lower rods. The mounting ring 32 is fitted from the lower rod and snapped into the slot 40. The reinforcing block 33 is tightly attached to the outside of the slot 40, achieving pre-installation of the mounting block 30 and the fixing block 4. The embedded mounting ring 32 ensures accurate positioning, and the tight attachment of the reinforcing block 33 on the outside effectively distributes the load. The overall operation is convenient, quick, and the structure is reliable.

[0025] In this application, the docking assembly 50 includes a first docking circle 500, a first tension spring 501, a first docking plate 502, and a pressing member 503. The mounting ring 32 has a mounting groove 320, with the groove opening facing the reinforcing block 33. The pull rod 2 passes through the reinforcing block. The first docking circle 500 is rotatably connected to the mounting groove 320 via a bearing and is connected to the corresponding inner wall of the reinforcing block 33. The first docking circle 500 has a first straight surface 5001, facing the top wall of the mounting groove 320. One end of the first tension spring 501 is connected to one end of the first straight surface 5001, and the other end faces the first straight surface 5001. The other end is inclined and fixed to the top wall of the mounting groove 320; one end of the first mating plate 502 is rotatably connected to the first mating circle 500, and the other end is provided with a first mating member that is opposite to the snap-fit ​​assembly 51, and the first mating circle 500 is provided with a first mating hole 5002 that is opposite to the snap-fit ​​assembly 51 at one end near the first tension spring 501; the pressing member 503 is connected to the mounting ring 32, and the pressing member 503 is used to press down on the end of the first mating circle 500 near the first mating hole 5002.

[0026] By using the pressing member 503 as the power input end, the force is transmitted to the first docking plate 502 through the rotational movement of the first docking circle 500, thereby controlling the engagement state of the first docking member and the locking assembly 51, and realizing the switching between locking and releasing. Specifically: when the operator presses down on the pressing member 503, the pressing member 503 acts directly on the end of the first docking circle 500 near the first docking hole 5002. Since the first docking circle 500 is rotatably connected to the mounting groove 320 through a bearing, this vertical pressure is converted into rotational torque, forcing the first docking circle 500 to deflect around its axis. At this time, the first tension spring 501 connected between the first straight surface 5001 and the top wall of the mounting groove 320 is further stretched, storing elastic potential energy to provide a power source for subsequent reset. At the same time, the first docking plate 502, which is rotatably connected to the first docking circle 500, swings synchronously with the circle, driving the first docking member at its end to lock with the locking assembly 51. After the pressing component 503 is released, the spring's restoring force pushes the first mating circle 500 to rotate in the opposite direction, causing the first mating plate 502 to reset, so that the first mating component is tightly embedded in the locking assembly 51, achieving automatic locking. When the operator presses the pressing component 503 down again, the first mating plate 502, which is rotatably connected to the first mating circle 500, swings synchronously with the circle, causing the first mating component at its end to exit from the locking groove of the locking assembly 51, thereby releasing the mechanical lock and allowing the mounting block 30 to separate from the slot 40. No wrenches or other auxiliary tools are required during operation, significantly reducing the operational threshold and time cost. Secondly, the self-adaptive reset function of the spring ensures a constant locking force in the non-pressed state, effectively resisting vibration and loosening during transportation and avoiding bolt corrosion problems.

[0027] In this application, the snap-fit ​​assembly 51 includes a second mating circle 510, a second tension spring 511, and a second mating plate 512. The second mating circle 510 is rotatably connected to the inner wall of the slot 40 facing the first mating circle 500; the second tension spring 511 has a second straight surface 5100 on the second mating circle 510, one end of the second tension spring 511 is connected to one end of the second straight surface 5100, and the other end is inclined and fixed to the top wall of the slot 40 facing the other end of the second straight surface 5100; the second mating plate 512 has one end rotatably connected to the second mating circle 510, and the other end is provided with a second mating member that mates with the first mating hole 5002, and the second mating circle 510 has a second mating hole 5101 that mates with the first mating member at one end near the second tension spring 511.

[0028] In this application, the first mating hole 5002 and the second mating hole 5101 are incomplete circular holes, both with openings. During the mating process, in the locked state, the second tension spring 511 pulls the second mating circle 510, causing the second mating piece to embed into the first mating hole 5002, while the first mating piece embeds into the second mating hole 5101, forming a cross-locking. When disassembly is required, the operator presses the pressing piece 503 on the mating assembly 50, forcing the first mating circle 500 to rotate around the bearing. This rotational action produces a dual effect: firstly, it causes the first mating plate 502 to swing, pulling the first mating piece out of the second mating hole 5101; secondly, it causes the first mating hole 5002 to shift, disengaging from the second mating piece's clamping. At this time, the bidirectional constraint is simultaneously released, and the saddle bracket 3 can be separated. After releasing the pressing piece 503, the restoring forces of the first tension spring 501 and the second tension spring 511 work together to drive the two circular bodies to rotate in the opposite direction and reset, and the mating piece automatically re-embeds into the mating hole, completing the self-locking.

[0029] In this application, both the first and second mating parts are configured as positioning rods 6. In the locked state, the first tension spring 501 pulls the first mating circle 500, causing the first positioning rod 6 at the end of the first mating plate 502 to embed into the second mating hole 5101 of the snap-fit ​​assembly 51; simultaneously, the second tension spring 511 pulls the second mating circle 510, causing the second positioning rod 6 at the end of the second mating plate 512 to embed into the first mating hole 5002 of the mating assembly 50, forming a cross-interlocking structure that effectively restricts relative displacement. During the unlocking process, the operator presses down on the pressing member 503, forcing the first mating circle 500 to rotate around the bearing. This action generates a linkage effect: on the one hand, the first mating plate 502 swings with the circle, pulling the first positioning rod 6 out of the second mating hole 5101; on the other hand, the first mating hole 5002 on the first mating circle 500 deviates from the second positioning rod 6 with rotation, releasing the constraint on the second positioning rod 6. At this time, both bidirectional locking is released, and the saddle bracket 3 can be easily separated. After releasing the pressing part 503, the spring's restoring force drives the mating circles on both sides to rotate in the opposite direction and reset. The positioning rod 6 automatically aligns and inserts into the mating hole, completing the self-locking process.

[0030] In this application, in order to limit the linear displacement of the first docking plate 502 and the second docking plate 512 during movement, a first limiting plate 7 parallel to the first docking plate 502 is provided at the top of the slot 300, and the side of the first limiting plate 7 near the first docking plate 502 is set as a first vertical limiting surface 70. A second limiting plate 8 parallel to the second docking plate 512 is provided at the bottom of the slot 40, and the side of the second limiting plate 8 near the second docking plate 512 is set as a second vertical limiting surface 80.

[0031] The linear displacement of the first docking plate 502 and the second docking plate 512 during movement is restricted by physical constraints. The core principle lies in utilizing the vertical limiting surfaces on the first limiting plate 7 and the second limiting plate 8, which form a tight fit with the sides of the first docking plate 502 and the second docking plate 512, respectively. This restricts the docking plates to rotate only along a preset trajectory, eliminating the degree of freedom of axial movement. In actual operation, when the pressing component 503 drives the docking circle to rotate, the docking plates swing accordingly. At this time, the first vertical limiting surface 70 and the second vertical limiting surface 80 act as rigid barriers, effectively blocking any linear offset of the docking plates along the axial direction. This constraint ensures that the positioning rod 6 on the docking plate always maintains precise coaxiality with the corresponding docking hole. It avoids alignment deviations caused by linear displacement, ensuring that the positioning rod 6 can smoothly insert into the docking hole.

[0032] This application further provides a sector-shaped groove 71 on the other side of the first limiting plate 7, and a sector-shaped portion 81 on the second limiting plate 8. The sector-shaped portion 81 engages with the sector-shaped groove 71. A locking component is provided between the first limiting plate 7 and the second limiting plate 8 to lock the sector-shaped portion 81 within the sector-shaped groove 71. The cooperation between the sector-shaped structure and the locking component further enhances the stability and safety of the connection between the saddle bracket 3 and the pull rod 2. Its core lies in using the curved surface cooperation between the sector-shaped portion 81 and the sector-shaped groove 71 to achieve self-guiding positioning, and using the locking component to achieve rigid fixation, complementing the internal installation and removal mechanism 5.

[0033] During installation, the operator places the mounting block 30 downwards, and the mounting ring 32 initially enters the slot 40. At this time, the fan-shaped portion 81 on the second limiting plate 8 begins to slide into the fan-shaped groove 71 of the first limiting plate 7, automatically correcting the angular deviation between the mounting block 30 and the fixing block 4 using curved surface guidance. Simultaneously, the vertical limiting surface of the limiting plate restricts the linear displacement of the mating plates. As the mounting block 30 continues to be pressed down, the mating assembly 50 on the mounting block 30 and the snap-fit ​​assembly 51 in the slot 40 gradually approach each other. Under the combined constraint of the fan-shaped structure and the limiting plate, the first mating plate 502 and the second mating plate 512 remain strictly parallel, ensuring precise alignment of the first positioning rod 6 with the second mating hole 5101 and the second positioning rod 6 with the first mating hole 5002. Under the elastic force of the first tension spring 501 and the second tension spring 511, the positioning rod 6 automatically embeds into the mating hole of the other, completing the internal mechanical interlock. Finally, the external locking component is used to fix the sector part 81 in the sector groove 71, completing the external rigid locking. The internal positioning rod 6 interlocks with the external sector lock to form redundancy, which greatly reduces the risk of accidental unlocking.

[0034] In this application, the locking assembly includes a support rod 90 and an elastic rod 91. The support rod 90 is fixed to the inner wall of the fan-shaped groove 71 and is arranged as a long rod. The elastic rod 91 is connected to the support rod 90 and is located at the lower part of the support rod 90. The elastic rod 91 has an outwardly protruding bow-shaped portion 910, a snap-fit ​​surface 911 on the bow-shaped portion 910, and a through groove 810 on the fan-shaped portion 81. A locking groove 811 is provided on the inner wall of the through groove 810. The elastic rod 91 passes through the through groove 810 so that the snap-fit ​​surface 911 snaps into the locking groove 811.

[0035] The operator lowers the mounting block 30, aligning the sector-shaped part 81 with the entrance of the sector-shaped groove 71. At this point, the positioning rod 6 of the internal docking assembly 50 is initially close to the second docking hole 5101 of the snap-fit ​​assembly 51. As the mounting block 30 continues to be pressed down, the sector-shaped part 81 slides into the sector-shaped groove 71, and the through groove 810 on the second limiting plate 8 fits into the support rod 90 and elastic rod 91 fixed to the inner wall of the sector-shaped groove 71. During this process, the arc-shaped part 910 of the elastic rod 91 undergoes elastic deformation under the pressure of the inner wall of the through groove 810, storing potential energy. When the mounting block 30 is in place, the positioning rod 6 of the internal docking assembly 50 is fully embedded in the docking hole under the action of the spring, completing the internal interlock; at the same time, the locking groove 811 in the through groove 810 moves exactly to the position of the snap-fit ​​surface 911 of the elastic rod 91, the elastic rod 91 instantly resets, and the snap-fit ​​surface 911 forcefully snaps into the locking groove 811, issuing locking feedback. The dual locking mechanism in this application provides enhanced security. The external locking component and the internal docking component 50 form redundant protection, greatly reducing the risk of loosening caused by transportation vibration. The flexible snap-fit ​​design ensures proper installation without the need for additional tools.

[0036] In this application, an abutment rod 900 is also provided on the support rod 90. A connecting spring 901 is fitted on the abutment rod 900. One end of the connecting spring 901 is connected to the abutment rod 900, and the other end is connected to the support rod 90. One end of the abutment rod 900 is used to abut against the bow-shaped part 910 so that the snap-fit ​​surface 911 is deformed. The other end of the abutment rod 900 is provided with a pressing rod 902. A pressing post 903 is provided on the first mating circle 500. The pressing post 903 is located above the pressing post 902. When the pressing member 503 presses down on the end of the first mating circle 500 near the first mating hole 5002, the pressing post 903 presses on the pressing post 902 to drive the abutment rod 900 to abut against the bow-shaped part 910.

[0037] When the operator presses down on the pressing part 503, the first mating circle 500 deflects, and the pressure column 903 fixed thereon moves accordingly, pressing down on the pressing rod 902. The pressing rod 902 pushes the abutment rod 900 downwards, overcoming the resistance of the connecting spring 901. The end of the abutment rod 900 directly abuts the arc-shaped part 910 of the elastic rod 91, forcing the locking surface 911 to deform and exit from the locking groove 811, thus releasing the external lock. At the same time, the deflection of the first mating circle 500 also causes the internal positioning rod 6 to be pulled out of the mating hole, releasing the internal interlock. This application only requires a single point press to complete all unlocking steps, eliminating the need to operate the internal and external locks separately, greatly improving loading and unloading efficiency; and the automatic reset is reliable. After releasing the pressing part 503, the connecting spring 901 and the internal tension spring work together to reset, ensuring that the locking mechanism automatically returns to the locked state, preventing accidental loosening during transportation.

[0038] In this application, the pressing component 503 includes a pressing rod 5030 and a return spring 5031. A through hole is provided at the top of the mounting ring 32, and the pressing rod 5030 is connected to the through hole. The return spring 5031 is sleeved on the pressing rod 5030, with one end connected to the pressing rod 5030 and the other end connected to the mounting ring 32. During operation, the operator presses down on the pressing rod 5030, compressing the return spring 5031 to store energy. The linear displacement of the pressing rod 5030 drives the internal first mating circle 500, the pressure column 903, and the abutment rod 900 to engage, simultaneously releasing the constraint between the internal mating assembly 50 and the external locking assembly, achieving rapid unlocking. After releasing the hand, the return spring 5031 releases its potential energy, pushing the pressing rod 5030 back to its original position, causing the internal mechanism to re-engage and lock.
