Description

Technical Field

[0001] This invention relates to the field of dual-purpose tippler technology, specifically to a dual-purpose tippler container crushing force testing and protection mechanism and its usage method. Background Technology

[0002] A tippler is a large mechanical device used to unload bulk materials from open railway wagons. It is a loading and unloading machine that can tilt or tilt rail vehicles to unload materials. It is suitable for ports with large transportation volumes and industrial sectors such as metallurgy, coal, and thermal power. Mining cars in mines are also mostly unloaded using small tipplers. A tippler can unload 1-4 wagons at a time. During use, the pressure force of the tippler needs to be tested regularly to prevent excessive pressure force from causing deformation at the stress point of the container, or insufficient pressure force from causing the container to fall off during clamping. The existing tippler's container pressure force detection structure is a pressure detection structure installed on the contact surface between the tippler's clamping parts and the container. The pressure sensor inside the pressure detection structure is directly subjected to force for detection. When the clamping force of the clamping parts exceeds the pressure sensor's stress limit, the pressure sensor will be damaged. Therefore, an overload protection structure needs to be set on the pressure sensor. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-purpose tippler container pressure testing and protection mechanism. By using this device, the problem of potential overload of the pressure sensor in the pressure detection structure of the existing tippler clamping components can be solved.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dual-purpose tipper container pressure testing and protection mechanism, including a clamping component, an installation component on one side of the clamping component, an overload protection component above the installation component, a pressure sensor inside the overload protection component, the installation component for installing the overload protection component on one side of the clamping component, and the overload protection component for overload protection when the pressure sensor is subjected to force exceeding the limit.

[0005] Preferably, the mounting assembly includes a mounting member disposed inside one side of the clamping member, a connecting member being movably connected inside the mounting member, and a spring being sleeved on one side of the connecting member.

[0006] Preferably, the mounting component has an internal movable hole and a slot on its front side.

[0007] Preferably, the connector has a pull rod at one end near the mounting component, a locking block at one end of the pull rod, and a connecting hole at one end of the connector. The pull rod matches the movable hole, and the locking block matches the locking groove.

[0008] Preferably, the overload protection component includes a sleeve fixed to the upper part of the connector by screws, a pressure sensor is provided inside the sleeve, a stop is movably connected to the outside of the pressure sensor, a bearing plate is fixedly connected to one end of the pressure sensor, a movable shaft is provided at the other end of the pressure sensor, a spring three is provided at the end of the movable shaft away from the pressure sensor, a bushing is sleeved on the outer surface of the movable shaft, and a spring two is provided at one end of the bushing.

[0009] Preferably, the support plate has a countersunk hole inside, and the support plate is fixed to the pressure sensor by screws passing through the countersunk hole.

[0010] Preferably, the sleeve has a first sliding groove inside, which matches the chassis, and a second sliding groove, a third sliding groove, a fourth sliding groove, a fifth sliding groove, and a sixth sliding groove are sequentially provided below the first sliding groove.

[0011] Preferably, the block has a transmission hole inside, which matches the data transmission port.

[0012] Preferably, a method for using a dual-purpose tippler container crushing force testing and protection mechanism includes the following steps:

[0013] S1. When there is no need for detection, the force-bearing surface of the pressure sensor faces the horizontal direction, and the overload protection component is fixed by the locking block into the slot.

[0014] S2. When testing is required, pull the connector to disengage the locking block from the slot. At this time, the pull rod slides in the movable hole and compresses the spring.

[0015] S3. Rotate the connecting piece so that the force-bearing surface of the pressure sensor faces the vertical direction. After loosening the connecting piece, the spring causes the locking block to engage with the slot, thus fixing the overload protection component and allowing the pressure sensor to bear force normally.

[0016] S4. When the pressure of the press is detected, the pressure is transmitted to the pressure sensor through the bearing plate. When the pressure sensor is subjected to excessive pressure, the chassis of the pressure sensor will push the movable shaft backward along the slide groove, causing the movable shaft to slide along the slide groove. At the same time, one end of the movable shaft will squeeze the spring.

[0017] S5. When the chassis of the pressure sensor is pushed backward a certain distance, it will open the compression bushing, causing the bushing to slide backward along the second slide groove and compress the second spring in the third slide groove until one end of the bearing plate is on the same plane as the clamping surface of the clamping member, so that the pressure on the pressure sensor no longer increases, thereby preventing the pressure sensor from being subjected to force exceeding the limit range.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention proposes a dual-purpose container pressure testing and protection mechanism for tippers. When the pressure is initially tested, the pressure is transmitted to the pressure sensor via a support plate. When the pressure sensor experiences excessive pressure, its base pushes backward against the movable shaft, which in turn compresses spring three. After the pressure sensor's base pushes backward a certain distance, it engages the compression sleeve, which in turn compresses spring two until one end of the support plate is flush with the clamping surface of the clamping component. This prevents the pressure on the pressure sensor from increasing further, ensuring that the pressure sensor's force does not exceed its limit. This provides overload protection for the pressure sensor, preventing damage due to excessive force during testing and extending its service life.

[0020] 2. The present invention proposes a dual-purpose container pressure testing and protection mechanism for tippers. When testing is required, pulling the connecting piece causes the locking block to disengage from the slot, and rotating the connecting piece causes the force-bearing surface of the pressure sensor to face the vertical direction. At this time, the spring is compressed. After releasing the connecting piece, the locking block is locked into the slot under the action of the spring. When testing is not required, rotating the connecting piece causes the force-bearing surface of the pressure sensor to face the horizontal direction. This avoids the need for repeated installation and disassembly of existing testing structures according to testing requirements, reduces workload, and is more practical. Attached Figure Description

[0029] The technical solutions of 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.

[0030] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0031] Combination Figures 1-7 A dual-purpose tipper container pressure testing and protection mechanism includes a clamping component 1, an installation component 2 on one side of the clamping component 1, an overload protection component 3 on the top of the installation component 2, and a pressure sensor 4 inside the overload protection component 3. The installation component 2 is used to install the overload protection component 3 on one side of the clamping component 1, and the overload protection component 3 is used to provide overload protection when the pressure sensor 4 is subjected to force exceeding the limit.

[0032] Mounting assembly 2 includes a mounting member 21 disposed inside one side of clamping member 1. A connecting member 23 is movably connected inside the mounting member 21. A spring 22 is sleeved on one side of the connecting member 23. A movable hole 211 is provided inside the mounting member 21. A slot 212 is provided on the front of the mounting member 21. A pull rod 231 is provided at one end of the connecting member 23 near the mounting member 21. A locking block 232 is provided at one end of the pull rod 231. A connecting hole 233 is provided at one end of the connecting member 23. The pull rod 231 matches the movable hole 211, and the locking block 232 matches the slot 212. When the 12 are matched, when testing is required, the connecting piece 23 is pulled to disengage the locking block 232 from the slot 212. At this time, the pull rod 231 slides in the movable hole 211 and drives the spring 22 to compress. The connecting piece 23 is rotated so that the force-bearing surface of the pressure sensor 4 is facing the vertical direction. After the connecting piece 23 is released, the locking block 232 is locked into the slot 212 for fixation under the action of the spring 22. When testing is not required, the connecting piece 23 is rotated so that the force-bearing surface of the pressure sensor 4 is facing the horizontal direction.

[0033] The overload protection assembly 3 includes a sleeve 32 fixed to the connector 23 by screws. A pressure sensor 4 is installed inside the sleeve 32, and a stop 33 is movably connected to the outside of the pressure sensor 4. The stop 33 prevents external dust from entering the sleeve 32, and the stop 33 can slide along the slide groove 326 inside the sleeve 32 along with the pressure sensor 4. A support plate 31 is fixedly connected to one end of the pressure sensor 4, and a movable shaft 36 is provided at the other end of the pressure sensor 4. A spring 37 is provided at the end of the movable shaft 36 away from the pressure sensor 4. A bushing 34 is sleeved on the outer surface of the movable shaft 36, and a spring 35 is provided at one end of the bushing 34. A countersunk hole 311 is opened inside the support plate 31, and the support plate 31 is fixed to the pressure sensor 4 by screws passing through the countersunk hole 311. A slide groove 32 is opened inside the sleeve 32. 1. Slide 1 321 matches the chassis 42. Slide 2 322, slide 323, slide 4 324, slide 5 325 and slide 6 326 are sequentially provided below slide 1 321. Transmission hole 331 is provided inside the stop block 33. Transmission hole 331 matches the data transmission port 41. When the pressure of the press is detected, the pressure is transmitted to the pressure sensor 4 through the bearing plate 31. When the pressure sensor 4 is subjected to excessive pressure, the chassis 42 of the pressure sensor 4 will push the movable shaft 36 backward. At the same time, the movable shaft 36 will push the spring 37. After the chassis 42 of the pressure sensor 4 pushes backward a certain distance, it will start to squeeze the bushing 34, so that the bushing 34 will squeeze the spring 2 35 until one end of the bearing plate 31 is on the same plane as the clamping surface of the clamping member 1, so that the pressure on the pressure sensor 4 no longer increases.

[0034] Working principle: When there is no testing requirement, the force-bearing surface of the pressure sensor 4 faces horizontally. The overload protection component 3 is fixed by the locking block 232 engaging with the slot 212, thus keeping the force-bearing surface of the pressure sensor 4 always horizontal. When testing is required, pulling the connecting piece 23 disengages the locking block 232 from the slot 212. At this time, the pull rod 231 slides in the movable hole 211, compressing the spring 22. Rotating the connecting piece 23 makes the force-bearing surface of the pressure sensor 4 face vertically. Releasing the connecting piece 23 allows the spring 22 to engage the locking block 232 with the slot 212, fixing the overload protection component 3 and allowing the pressure sensor 4 to bear force normally. This is necessary when starting to test the pressure on the vehicle. During testing, pressure is transmitted to pressure sensor 4 through bearing plate 31. When the pressure on pressure sensor 4 is too high, the base 42 of pressure sensor 4 will push the movable shaft 36 backward along slide groove 321, causing the movable shaft 36 to slide along slide groove 325. At the same time, one end of the movable shaft 36 will squeeze spring 37. After the base 42 of pressure sensor 4 pushes backward a certain distance, it will squeeze the bushing 34, causing the bushing 34 to slide backward along slide groove 322 and squeeze spring 35 in slide groove 323 until one end of bearing plate 31 is on the same plane as the clamping surface of clamping member 1, so that the pressure on pressure sensor 4 no longer increases, thereby preventing pressure sensor 4 from being subjected to force exceeding the limit range.
