Description

Technical Field

[0001] This utility model relates to the field of maintenance tool technology, specifically to a clamping and disassembling device for cylindrical objects. Background Technology

[0002] Air dryer cans, as crucial filtering devices connecting the air compressor and the air tank, function to absorb moisture from compressed air, ensuring the output compressed air remains dry. Air dryer cans are consumable products and require periodic replacement. Failure to replace the dryer can for an extended period may lead to brake failure and shorten the lifespan of related components, especially in harsh weather conditions, potentially severely impacting driving safety.

[0003] While air dryer canisters are easily installed onto the air dryer valve body during the initial setup of a new machine, over time, the threads on the valve body gradually corrode, making disassembly difficult. Alternatively, repeated replacements can cause wear on the threads, further complicating disassembly. Furthermore, the air compressor connected to the valve body frequently pumps and stores air through the canister, often creating negative pressure on the canister after the engine stops, making removal even more challenging. Because the air dryer canister is cylindrical, current technology typically uses belt-operated wrenches for disassembly and assembly. However, belt-operated wrenches are prone to slipping and loosening, making disassembly difficult; they are also frequently damaged, resulting in low reliability. Sometimes, operators are forced to resort to destructive disassembly, leading to significant waste of parts. Moreover, belt-operated wrenches have a short lifespan, and frequent replacements increase costs. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used in this document do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0028] like Figures 1 to 4 As shown, the clamping and disassembly device for cylindrical objects includes a mounting base 1. Two opposing arc-shaped bracket assemblies are provided on both sides of the mounting base 1. The upper end of one arc-shaped bracket assembly is hinged to one end of a rotating arm 2, and the other end of the rotating arm 2 is detachably and fixedly connected to the upper end of the other arc-shaped bracket assembly.

[0029] The mounting base 1, two arc-shaped bracket assemblies, and the rotating arm 2 form a receiving area 21. Within the receiving area 21, top blocks are respectively provided on the rotating arm 2 and the mounting base 1. The two top blocks are positioned opposite each other, and the position of at least one top block is adjustable vertically. An adjustment mechanism is provided between the mounting base 1 and the two arc-shaped bracket assemblies to adjust the distance between the two arc-shaped bracket assemblies. In other words, the distance between the two arc-shaped bracket assemblies is adjustable.

[0030] like Figure 3 As shown, the adjustment mechanism includes a drive shaft 3, two coaxial driven adjustment shafts, a drive bevel gear 4 fixedly connected to the drive shaft 3, and a driven bevel gear fixedly connected to the driven adjustment shaft. The mounting base 1 is provided with a mounting cavity. The drive bevel gear 4 meshes with the two driven bevel gears respectively and is installed in the mounting cavity. The driven adjustment shaft is perpendicular to the drive shaft 3. The drive shaft 3 is rotatably connected to the mounting base 1 and one end protrudes from the mounting base 1. The driven adjustment shaft is rotatably connected to the mounting base 1 and partially extends out of the mounting base 1. The protruding part of the driven adjustment shaft passes through the arc-shaped bracket assembly. When the drive shaft 3 is rotated, the two arc-shaped bracket assemblies are connected and simultaneously displaced inward or outward along the driven adjustment shaft.

[0031] The aforementioned drive shaft 3 can be fixedly connected to the driving bevel gear 4 via a spline. The driven adjusting shaft is fixedly connected to the driven bevel gear via a standard flat key.

[0032] like Figure 3 As shown, the mounting base 1 has a driven shaft hole for the driven adjustment shaft to pass through. A wear-resistant stepped nut 20 is installed between the driven shaft hole and the driven adjustment shaft, and the wear-resistant stepped nut 20 is located at the outer end of the driven shaft hole. The wear-resistant stepped nut 20 can reduce the axial wear of the driven adjustment shaft, facilitate timely replacement, and ensure coaxiality during use.

[0033] In some embodiments, the portion of the driven adjustment shaft extending out of the mounting base 1 is designated as the driven adjustment shaft extension section. One end of the arc-shaped bracket assembly has a bracket mounting hole through which the driven adjustment shaft extension section passes, and the arc-shaped bracket assembly is threadedly connected to the driven adjustment shaft extension section. The bracket mounting hole is threadedly connected to the driven adjustment shaft extension section.

[0034] In some embodiments, the portion of the driven adjusting shaft extending out of the mounting base 1 is designated as the driven adjusting shaft extension section. One end of the arc-shaped bracket assembly has a bracket mounting hole for the driven adjusting shaft extension section to pass through. The bracket mounting hole can be a smooth hole. An adjusting nut 19 is threaded onto the driven adjusting shaft extension section. In this case, the adjusting nut 19 can be screwed to a position close to the outer side of the arc-shaped bracket assembly. Alternatively, the bracket mounting hole can be a threaded hole, allowing the adjusting nut 19 to be positioned near the outer end of the driven adjusting shaft, thus acting as a shaft end limiter and preventing the arc-shaped bracket assembly from dislodging from the driven adjusting shaft extension section.

[0035] The top block on the mounting base 1 is the first top block 5, and the top block on the rotating arm 2 is the second top block 6. To prevent slippage when clamping cylindrical objects, anti-slip pads can be fixed on both the first top block 5 and the second top block 6.

[0036] The first top block 5 is an adjustable top block, which includes a connecting rod portion 51 and a top block portion 52 fixedly connected to the connecting rod portion 51. The drive shaft 3 has a shaft hole, and the mounting base 1 has a mounting base hole. The shaft hole and the mounting base hole are coaxially arranged. The connecting rod portion 51 passes through the mounting base hole and the shaft hole, and one end extends out of the drive shaft 3. The connecting rod portion 51 is threadedly connected to the mounting base hole. The connecting rod portion 51 is rotatably connected to the shaft hole.

[0037] A directional handle 7 is fixed to one end of the connecting rod 51 extending from the drive shaft 3. The directional handle 7 is threadedly connected to the connecting rod 51, and further, a baffle plate locks the directional handle 7 and the connecting rod 51 together. Of course, the directional handle 7 and the connecting rod 51 can also be welded together. Rotating the directional handle 7 can push the first top block 5 upward or retract it downward, achieving more precise feeding and retraction of the air drying tank 22.

[0038] The second top block 6 can be a fixed top block, which is fixedly mounted on the rotating arm 2 with screws. Alternatively, the second top block 6 can be an adjustable top block, with the screws being long adjustment screws. The position of the top block is adjusted by screwing the long adjustment screw into the top block. Furthermore, the top blocks on the rotating arm 2 are connected by hexagonal head bolts, and both the top blocks and the hexagonal head bolts can rotate to match the replenishment position dimensions of the air drying tank 22 in the length direction.

[0039] The two coaxial driven adjustment shafts are the first driven adjustment shaft 8 and the second driven adjustment shaft 9, respectively. The two driven bevel gears are the first driven bevel gear 10 and the second driven bevel gear 11, respectively. The first driven adjustment shaft 8 is fixedly connected to the first driven bevel gear 10 and one end extends out of the mounting base 1. The second driven adjustment shaft 9 is fixedly connected to the second driven bevel gear 11 and one end extends out of the mounting base 1. The extended ends of the first driven adjustment shaft 8 and the second driven adjustment shaft 9 are respectively threadedly connected to the arc-shaped bracket assembly. When the drive shaft 3 is rotated, the drive bevel gear 4 rotates and drives the first driven adjustment shaft 8 and the second driven adjustment shaft 9 to rotate through the driven bevel gears. This causes the two arc-shaped bracket assemblies to move inward or outward simultaneously along the driven adjustment shafts, thus adapting to the clamping of cylindrical objects of different diameters.

[0040] In some embodiments, the arc-shaped bracket assembly includes a guard 12 and a bracket 13, which are connected by a pin 14 and a first nut 15. Specifically, the first nut 15 is preferably a type I hexagonal nut, and the guard can rotate about an axis centered on the pin 14.

[0041] The bracket 13 includes an upper connecting end, an arc-shaped part, and a lower connecting end. The upper connecting end has a first U-shaped groove, and the lower connecting end has a second U-shaped groove. The upper end of the guard 12 is located in the second U-shaped groove and is hinged to the lower connecting end by a pin 14. The pin 14 is threadedly connected to the first nut 15. When the guard 12 does not need to rotate relative to the bracket 13, the first nut 15 can be locked.

[0042] The lower end of the guard 12 is provided with a guard hole for the extended section of the driven adjustment shaft to pass through. The two arc-shaped bracket assemblies are a left arc-shaped bracket assembly and a right arc-shaped bracket assembly. The left arc-shaped bracket assembly includes a left guard 12a and a left bracket 13a, and the right arc-shaped bracket assembly includes a right guard 12b and a right bracket 13b. The upper end of the left arc-shaped bracket assembly is hinged to the left end of the rotating arm 2. Specifically, the left end of the rotating arm 2 is located in the first U-shaped groove of the connecting end of the left bracket 13a and is hinged with a pin 14. A detachable fixed connection structure is provided between the first U-shaped groove of the right bracket 13b and the right end of the rotating arm 2, which can fix the right end of the rotating arm 2 to the right bracket 13b. The rotating arm 2 can rotate clockwise or counterclockwise around the pin 14, and the left bracket 13a can rotate clockwise or counterclockwise around the pin 14.

[0043] In some embodiments, the right end of the rotating arm 2 has an axially extending elongated hole for mounting a pin. Both sides of the first U-shaped groove of the right bracket 13b have pin through holes. The pin is inserted and fixed to the right end of the rotating arm 2 and the right bracket 13b through the positioning pin mounting hole and the pin through hole. A locking nut 17 is threaded onto the right end of the rotating arm 2, located to the right of the pin. By tightening the locking nut 17 and removing the pin, the relative distance between the left bracket 13a and the right bracket 13b can be adjusted to meet the requirements of different sizes of the air dryer 22 (or other cylindrical objects).

[0044] In some embodiments, a rotating block 16 is sleeved on the right end of the rotating arm 2. The rotating block 16 is located in the first U-shaped groove of the connecting end of the right arc-shaped bracket assembly. The connecting end of the right arc-shaped bracket assembly is fixedly connected to the rotating block 16 by bolts 18. A locking nut 17 is threadedly connected to the right end of the rotating arm 2, and the locking nut 17 is located on the right side of the rotating block 16. Specifically, two bolts 18 for fixing the rotating block 16 are installed on the two side walls of the first U-shaped groove. The bolts 18 are preferably hexagonal head bolts. Tightening the locking nut 17, bolts 18, and first nut 15 can adjust the relative distance between the left bracket 13a and the right bracket 13b to meet the requirements of different sizes of air dryer canisters 22 (or other cylindrical objects). It can not only adapt to various shapes of air dryer canisters, but also remove and assemble air dryer canisters of different specifications, making it highly versatile. It can reduce the number of different specifications of air dryer canister disassembly devices.

[0045] This utility model's clamping and disassembling device for cylindrical objects clamps the cylindrical object, and by manipulating the device, the cylindrical object can be rotated to disassemble it from the threaded connection. The operation is convenient and reliable, greatly reducing disassembly difficulty and improving assembly and disassembly efficiency. Furthermore, the clamping and disassembly device is not easily damaged. In addition, the clamping and disassembly device for cylindrical objects has a simple structure, making it easy to process and manufacture.

[0046] Combination Figure 2 , Figure 3 and Figure 5 As shown, the clamping and disassembly device for cylindrical objects operates on the following principle for clamping the air drying canister 22:

[0047] When facing the drive shaft 3, rotating the drive shaft 3 counterclockwise will cause the driving bevel gear 4 to rotate counterclockwise, which in turn will cause the two driven bevel gears to rotate clockwise. This will cause the two driven adjusting shafts to rotate, moving the left bracket 13 assembly and adjusting nut 19 on the first driven adjusting shaft 8 to the left, and simultaneously moving the right arc-shaped bracket assembly and adjusting nut 19 on the second driven adjusting shaft 9 to the right. In other words, both the left bracket assembly and the right arc-shaped bracket assembly move outwards, increasing the distance between them, thus allowing the large-sized air drying canister 22 to be tightened. Then, the first nut 15 on the pin 14 between the guard 12 and the bracket 13 is tightened to lock the desired size. Similarly, rotating the drive shaft 3 clockwise will cause both the left bracket 13 assembly and the right arc-shaped bracket assembly to move inwards, decreasing the distance between them, thus allowing the small-sized air drying canister 22 to be tightened. The cylindrical object clamping and disassembling device can disassemble the air dryer 22 by rotating it after clamping it, so as to facilitate the replacement of the air dryer 22.

[0048] This utility model's clamping and disassembling device for cylindrical objects can be used not only for disassembling and assembling air dryers, but also for clamping and disassembling other cylindrical objects. After clamping the cylindrical object, manipulating the clamping and disassembling device allows the cylindrical object to be rotated to be disassembled from the threaded connection. The operation is convenient and reliable, greatly reducing the difficulty of disassembly and improving the efficiency of assembly and disassembly.

[0049] This utility model is not limited to the above embodiments. All improvements made based on the concept, principle, structure and method of this utility model are within the protection scope of this utility model.
