Description

Technical Field

[0001] This invention relates to the field of natural gas vehicle gas supply system technology, and in particular to a natural gas cylinder frame locking device. Background Technology

[0002] Natural gas vehicles are automobiles primarily powered by combustion engines and can be divided into two types: liquefied petroleum gas (LPG) vehicles and compressed natural gas (CNG) vehicles. Natural gas vehicles primarily use natural gas as fuel. The gas supply system of a natural gas vehicle mainly consists of gas cylinders and a valve system. Large natural gas vehicles require multiple gas cylinders for operation, and these cylinders are typically secured to the vehicle using a natural gas cylinder frame.

[0003] Chinese invention patent application number 201510152327.5 discloses a conveniently assembled and disassembled upper and lower double gas cylinder storage frame, including at least two upper and lower double gas cylinder support template frames. All upper and lower double gas cylinder support template frames are fixed together by connecting plates. The structure of the upper and lower double gas cylinder support template frame is as follows: it includes an integrally formed upper and lower double gas cylinder support template frame body. The top of the upper and lower double gas cylinder support template frame body is provided with an upper arc-shaped gas cylinder seat adapted to the body of a liquefied natural gas cylinder. The upper and lower double gas cylinder support template frame body below the upper arc-shaped gas cylinder seat is provided with an installation hole for the liquefied natural gas cylinder to pass through. The bottom side of the installation hole is provided with a lower arc-shaped gas cylinder seat adapted to the body of a liquefied natural gas cylinder. The upper arc-shaped gas cylinder seats of all the upper and lower double gas cylinder support template frames form a first placement platform for placing one liquefied natural gas cylinder, and the lower arc-shaped gas cylinder seats of the installation holes of all the upper and lower double gas cylinder support template frames form a second placement platform for placing another liquefied natural gas cylinder. This cylinder storage frame is only suitable for storing two gas cylinders, which has a small storage capacity. Furthermore, after the gas cylinders are placed, they need to be manually secured one by one using straps, which is inconvenient to operate. Summary of the Invention

[0004] The purpose of this invention is to provide a natural gas cylinder frame locking device, which can store multiple gas cylinders, automatically fix the gas cylinders, and is easy to operate.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a natural gas cylinder frame locking device, comprising a frame, wherein multiple layers of support frames are uniformly arranged in the vertical direction within the frame, and each layer of the support frame is provided with a plurality of cylinder fixing frames. Each cylinder fixing frame includes a placement groove fixedly connected to the support frame and a drive frame slidably connected to the support frame. The placement groove is provided with a plurality of fixing straps, and a cavity is provided within the placement groove. A drive assembly is provided within the cavity, and the drive assembly is connected to the fixing straps and the drive frame respectively. When the drive frame moves away from the placement groove, the two ends of the fixing straps move downward through the drive assembly.

[0006] By adopting the above technical solution, the frame is equipped with multiple support frames, each with several gas cylinder fixing frames. Multiple gas cylinders can be placed within the gas cylinder frame. A drive frame is slidably connected to the support frame, and a fixing strap is provided on the placement slot. A cavity is provided within the placement slot, and a drive assembly is located within the cavity. The drive assembly is connected to both the fixing strap and the drive frame. When the drive frame moves away from the placement slot, the drive assembly drives both ends of the fixing strap downwards. When placing a gas cylinder, it is placed in the placement slot with the fixing strap above the cylinder. Then, the tail end of the cylinder is placed on the drive frame. When the cylinder is pushed into the frame, the tail end of the cylinder drives the drive frame away from the placement slot, thereby driving both ends of the fixing strap downwards. Once the cylinder is completely pushed into the frame, the fixing strap tightens around the cylinder under the action of the drive assembly. Through the drive device, the cylinder is locked simultaneously during placement, eliminating the need for manual fixing with straps, making the operation simple and quick.

[0007] A further configuration of the present invention is as follows: each of the placement slots is provided with two fixing straps, and a through hole is provided above the placement slot for the fixing straps to pass through. The lower end of the fixing strap passes through the through hole and is located in the cavity. A driving assembly is provided on each side of the cavity. The driving assembly includes two guide wheels rotatably connected in the cavity. The two guide wheels are respectively located below the fixing straps. A central rotating wheel is rotatably connected in the cavity. A connecting rod is fixedly connected to the driving frame. The connecting rod is slidably connected in the cavity. A driving wheel is rotatably connected to the connecting rod. One end of the driving rope is connected to the lower end of a fixing strap, and after being wound around the guide wheel, the central rotating wheel, and the driving wheel in sequence, the other end is connected to the lower end of another fixing strap.

[0008] By adopting the above technical solution, the two ends of the fixing strap are inserted into the through holes of the placement slot, and the lower end of the fixing strap is connected to the drive assembly. The drive assembly drives the two ends of the fixing strap to move downward, thereby fixing the gas cylinder. The drive assembly includes a drive rope. One end of the drive rope is connected to the lower end of a fixing strap, and after being wound around the guide wheel, the central rotating wheel, and the drive wheel in sequence, the other end is connected to the lower end of another fixing strap. When the drive frame moves away from the placement slot, the drive frame drives the connecting rod and the drive wheel on the connecting rod to move. The drive wheel can simultaneously drive the two fixing straps to move downward through the drive rope. In addition, the drive wheel also acts as a movable pulley. The force of the gas cylinder pushing the drive plate can be converted into a larger force to pull the fixing strap downward, so that the fixing strap tightens the gas cylinder.

[0009] A further feature of the present invention is that: a ratchet rack is provided on the connecting rod, the ratchet rack is inclined toward the placement groove, a pawl is rotatably connected inside the cavity, the pawl is connected to the inner wall of the cavity through a spring, and the elastic force of the spring drives the pawl to engage with the ratchet rack.

[0010] By adopting the above technical solution, the connecting rod is equipped with a ratchet rack and the cavity is equipped with a pawl. Under the action of the pawl, the connecting rod can only move away from the placement slot, which can lock the fixing belt and prevent the fixing belt from loosening.

[0011] A further configuration of the present invention is as follows: two pawls located in the same placement slot cavity are connected by a connecting rod, the connecting rod is slidably connected to the placement slot, the side wall of the placement slot is provided with a circular hole for the connecting rod to pass through, one end of the connecting rod passing through the circular hole is provided with a handle, a second spring is provided between the handle and the placement slot, the elastic force of the second spring drives the connecting rod to move into the cavity, the other end of the connecting rod is provided with a buffer block, when the buffer block is in contact with the inner wall of the cavity, the pawl is in contact with the ratchet rack.

[0012] By adopting the above technical solution, the two pawls are connected by a connecting rod. Pulling the connecting rod can control the movement of the two pawls simultaneously. One end of the connecting rod is located outside the side wall of the placement groove. Pulling the handle can cause the pawls to disengage from the ratchet rack through the connecting rod, thereby allowing the connecting rod to move towards the placement groove, thus loosening the fixing strap. A second spring is provided between the handle and the placement groove. The elastic force of the second spring drives the connecting rod to move into the cavity. Therefore, when the handle is released, the second spring can drive the connecting rod to move into the cavity, so that the buffer block at the other end of the connecting rod contacts the inner wall of the cavity, and at the same time, the pawls engage with the ratchet rack.

[0013] A further feature of the present invention is that a spring three is provided inside the cavity, one end of the spring three is fixedly connected to the inner wall of the cavity and the other end is fixedly connected to a connecting rod, and the elastic force of the spring drives the connecting rod to move towards the placement groove.

[0014] By adopting the above technical solution, a spring three is provided inside the cavity. Under the action of the spring three, when the handle is pulled outward, the spring three can drive the connecting rod to move towards the placement slot. At the same time as loosening the fixing strap, the gas cylinder can also be moved outward, making it easier to take out the gas cylinder.

[0015] A further feature of the present invention is that the fixing belt includes two vertical plates slidably connected to the placement groove, the two vertical plates are connected at the top by an arc-shaped belt, a connecting plate is fixedly connected at the bottom of the vertical plates, and the connecting plate is provided with a connecting hole for connecting a drive rope.

[0016] By adopting the above technical solution, the fixing belt includes a vertical plate and an arc-shaped belt. The vertical plate is slidably connected in the placement groove, which facilitates the drive rope to pull the fixing belt downward. A connecting plate is provided below the vertical plate. The connecting plate can be made of a hard metal or other materials. The connecting plate has connecting holes to facilitate the fixed connection of the drive rope.

[0017] A further feature of the present invention is that the drive frame is L-shaped.

[0018] By adopting the above technical solution, the drive frame is set to L-shape, and the tail of the gas cylinder is connected to the drive frame. Pushing the gas cylinder into the frame can drive the drive frame to move.

[0019] The beneficial effects of this invention are:

[0020] 1. The natural gas cylinder frame of the present invention has multiple layers, each layer has two placement slots, which can hold multiple gas cylinders. The gas cylinders are placed on the placement slots, so that the fixing straps are above the gas cylinders. Then, while pushing the gas cylinders into the frame, the fixing straps can fix the gas cylinders under the action of the driving component. The gas cylinder installation operation is simple and quick.

[0021] 2. The drive assembly is connected to two fixing belts simultaneously. The same drive assembly can move the lower ends of both fixing belts downwards, ensuring consistent fixing time and tension, thus securing the gas cylinder more firmly and preventing it from tilting due to uneven force. Furthermore, the drive wheel in the drive assembly also functions as a pulley; the force exerted by the gas cylinder on the drive plate is converted into a greater force that pulls the fixing belts downwards, tightening them around the gas cylinder.

[0029] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example: A locking device for a natural gas cylinder frame 12, such as Figure 1 As shown, the device includes a frame 1, with multiple support frames 2 evenly arranged vertically inside the frame 1. Each support frame 2 has several gas cylinder 12 fixing frames 3. Each gas cylinder 12 fixing frame 3 includes a placement groove 31 fixedly connected to the support frame 2 and a drive frame 32 slidably connected to the support frame 2. The placement groove 31 has several fixing straps 33. The placement groove 31 has a cavity, and the cavity has a drive assembly 4. The drive assembly 4 is connected to the fixing straps 33 and the drive frame 32 respectively. When the drive frame 32 moves away from the placement groove 31, it drives the two ends of the fixing straps 33 to move downward through the drive assembly 4.

[0031] like Figure 1 As shown, the frame is provided with multiple support frames 2, and each support frame 2 is provided with several gas cylinder 12 fixing frames 3. Multiple gas cylinders 12 can be placed in the gas cylinder 12 frame. A drive frame 32 is slidably connected to the support frame 2. A fixing strap 33 is provided on the placement groove 31. A cavity is provided in the placement groove 31. A drive component 4 is provided in the cavity. The drive component 4 is connected to the fixing strap 33 and the drive frame 32 respectively. When the drive frame 32 moves away from the placement groove 31, the two ends of the fixing strap 33 are driven downward by the drive component 4. When placing the gas cylinder 12, it is placed in the placement groove 31 so that the fixing strap 33 is above the gas cylinder 12. Then the tail of the gas cylinder 12 is placed on the drive frame 32. When the gas cylinder 12 is pushed into the frame, the tail of the gas cylinder 12 drives the drive frame 32 to move away from the placement groove 31, thereby driving the two ends of the fixing strap 33 to move downward. When the gas cylinder 12 is completely pushed into the frame, the fixing strap 33 tightens the gas cylinder 12 under the action of the drive component 4. The gas cylinder 12 can be locked at the same time as it is placed using the drive device, eliminating the need for manual fixing with straps, making the operation simple and quick.

[0032] like Figure 2 , Figure 3As shown, each placement slot 31 is provided with two fixing straps 33. The placement slot 31 is provided with a through hole for the fixing straps 33 to pass through. The lower end of the fixing strap 33 passes through the through hole and is located in the cavity. A drive assembly 4 is provided on each side of the cavity. The drive assembly 4 includes two guide wheels 41 rotatably connected in the cavity. The two guide wheels 41 are located below the fixing straps 33. A central rotating wheel 42 is rotatably connected in the cavity. A connecting rod 43 is fixedly connected to the drive frame 32. The connecting rod 43 is slidably connected in the cavity. A drive wheel 44 is rotatably connected to the connecting rod 43. One end of the drive rope 45 is connected to the lower end of a fixing strap 33. After being wound around the guide wheel 41, the central rotating wheel 42, and the drive wheel 44 in sequence, the other end is connected to the lower end of another fixing strap 33.

[0033] like Figure 2 , Figure 3 As shown, the two ends of the fixing strap 33 are inserted into the through holes of the placement slot 31. The lower end of the fixing strap 33 is connected to the drive assembly 4. The drive assembly 4 drives the two ends of the fixing strap 33 to move downward, thereby fixing the gas cylinder 12. The drive assembly 4 includes a drive rope 45. One end of the drive rope 45 is connected to the lower end of a fixing strap 33, and is sequentially wound around the guide wheel 41, the central rotating wheel 42, and the drive wheel 44. The other end is connected to the lower end of another fixing strap 33. When the drive frame 32 moves away from the placement slot 31, the drive frame 32 drives the connecting rod 43 and the drive wheel 44 on the connecting rod 43 to move. The drive wheel 44 can simultaneously drive the two fixing straps 33 to move downward through the drive rope 45. The drive wheel 44 also acts as a movable pulley. The force of the gas cylinder 12 pushing the drive plate can be converted into a greater force to pull the fixing strap 33 downward, so that the fixing strap 33 tightens the gas cylinder 12.

[0034] like Figure 4 As shown, the connecting rod 43 is equipped with a ratchet rack 5, which is inclined towards the placement groove 31. A pawl 6 is rotatably connected inside the cavity, and the pawl 6 is connected to the inner wall of the cavity via a spring 7. The elastic force of the spring 7 drives the pawl 6 to engage with the ratchet rack 5. With the ratchet rack 5 on the connecting rod 43 and the pawl 6 inside the cavity, the connecting rod 43 can only move away from the placement groove 31 under the action of the pawl 6, which can lock the fixing strap 33 and prevent it from loosening.

[0035] like Figure 3As shown, two pawls 6 located in the same placement slot 31 cavity are connected by a connecting rod 8. The connecting rod 8 is slidably connected to the placement slot 31. The side wall of the placement slot 31 is provided with a round hole for the connecting rod 8 to pass through. One end of the connecting rod 8 that passes through the round hole is provided with a handle 9. A second spring 11 is provided between the handle 9 and the placement slot 31. The elastic force of the second spring 11 drives the connecting rod 8 to move into the cavity. The other end of the connecting rod 8 is provided with a buffer block. When the buffer block is in contact with the inner wall of the cavity, the pawl 6 is in contact with the ratchet rack 5. Two pawls 6 are connected by a connecting rod 8. Pulling the connecting rod 8 can simultaneously control the movement of both pawls 6. One end of the connecting rod 8 is located outside the side wall of the placement groove 31. Pulling the handle 9 can cause the pawls 6 to disengage from the ratchet rack 5 via the connecting rod 8, thereby allowing the connecting rod 43 to move towards the placement groove 31, thus loosening the fixing strap 33. A second spring 11 is provided between the handle 9 and the placement groove 31. The elastic force of the second spring 11 drives the connecting rod 8 to move into the cavity. Therefore, when the handle 9 is released, the second spring 11 can drive the connecting rod 8 to move into the cavity, so that the buffer block at the other end of the connecting rod 8 contacts the inner wall of the cavity, and at the same time, the pawls 6 engage with the ratchet rack 5.

[0036] like Figure 3 As shown, a spring 10 is installed inside the cavity. One end of the spring 10 is fixedly connected to the inner wall of the cavity, and the other end is fixedly connected to the connecting rod 43. The spring force drives the connecting rod 43 to move towards the placement groove 31. With the spring 10 inside the cavity, when the handle 9 is pulled outward under the action of the spring 10, the spring 10 can drive the connecting rod 43 to move towards the placement groove 31. At the same time as loosening the fixing strap 33, the gas cylinder 12 can also be moved outward, making it easier to remove the gas cylinder 12.

[0037] like Figure 5 As shown, the fixing strap 33 includes two vertical plates 331 slidably connected to the placement groove 31. The two vertical plates 331 are connected at the top by an arc-shaped strap 332. A connecting plate 333 is fixedly connected to the bottom of the vertical plates 331. The connecting plate 333 has a connecting hole 334 for connecting the drive rope 45. The fixing strap 33 includes vertical plates 331 and arc-shaped strap 332. The vertical plates 331 are slidably connected in the placement groove 31, which facilitates the drive rope 45 to pull the fixing strap 33 downward. The connecting plate 333 is located below the vertical plates. The connecting plate 333 can be made of a hard metal or other materials. The connecting plate 333 has a connecting hole 334 for the drive rope 45 to be fixedly connected.

[0038] The drive frame 32 is L-shaped. The drive frame 32 is L-shaped, and the tail of the gas cylinder 12 is connected to the drive frame 32. Pushing the gas cylinder 12 into the frame 1 will move the drive frame 32.
