[0002] Currently, the PTA tanker unloading shut-off valve is malfunctioning and needs to be disassembled and repaired. To prevent the unloading dust removal device from falling or becoming misaligned, complex scaffolding needs to be erected, and multiple manual hoists need to be used for simultaneous hoisting. Disassembly requires multiple workers, and improper operation can cause damage to the dust removal device and connecting hoses, resulting in poor disassembly efficiency. Due to the high-altitude and complex nature of the work, personnel are prone to fall accidents.

[0003] Therefore, there is an urgent need for a tool for quickly disassembling the PTA tank truck unloading shut-off valve. Utility Model Content

[0005] This utility model discloses a quick disassembly tool for a PTA tank truck unloading shut-off valve, including an upper limit block, a connecting arm, a lower limit block, a centering pin, and a gap adjusting pin. The upper limit block and the lower limit block are respectively fixed to both ends of the connecting arm. Two positioning holes are provided on both the upper limit block and the lower limit block. The centering pin cooperates with the positioning hole on the upper limit block, and the gap adjusting pin cooperates with the positioning hole on the lower limit block. The hole spacing of the two positioning holes on the upper limit block and the lower limit block is consistent with the hole spacing of two adjacent bolt holes on the pipe flange of the unloading shut-off valve.

[0006] The distance between the upper limit block and the lower limit block is 3-10mm greater than the distance between the outer sides of the flanges on both sides of the PTA tanker unloading shut-off valve pipeline.

Attached Figure Description

[0012] Figure 2 This is a schematic diagram illustrating the use of this utility model. Detailed Implementation

[0013] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1:

[0015] like Figure 1 , Figure 2 As shown, this utility model discloses a quick disassembly tool for a PTA tank truck unloading shut-off valve, including an upper limit block 1, a connecting arm 3, a lower limit block 2, a centering pin 4, and a gap adjusting pin 5. The upper limit block 1 and the lower limit block 2 are respectively fixed to both ends of the connecting arm 3. Two positioning holes are provided on both the upper limit block 1 and the lower limit block 2. The centering pin 4 cooperates with the positioning hole on the upper limit block 1, and the gap adjusting pin 5 cooperates with the positioning hole on the lower limit block 2. The hole spacing of the two positioning holes on the upper limit block 1 and the lower limit block 2 is consistent with the hole spacing of two adjacent bolt holes on the pipe flange 7 of the unloading shut-off valve 6.

[0016] The connecting arm 3 can be welded to the upper limit block 1 and the lower limit block 2. Full welding is used on the outside, and no welding is required on the inside to prevent the weld from affecting the assembly during use and causing interference to the flange 7.

[0017] During use, i.e. when disassembling the material shut-off valve 6, the upper limit block 1 and the lower limit block 2 are respectively connected to the pipe flange 7 of the material shut-off valve 6. The positioning holes on the upper limit block 1 and the lower limit block 2 correspond to the bolt holes on the pipe flange 7 of the material shut-off valve 6, and are connected by the centering pin 4 and the clearance adjusting pin 5, so that the position of the dust removal device 8 can be kept stable and safe and reliable during disassembly.

[0018] The clearance between the upper limit block 1 and the lower limit block 2 is 3-10mm larger than the distance between the outer sides of the flanges 7 on both sides of the PTA tank truck unloading shut-off valve 6 pipeline. The clearance between the upper limit block 1 and the lower limit block 2 is slightly larger than the outer sides of the flanges 7 on both sides of the PTA tank truck unloading shut-off valve 6 pipeline. This allows the upper limit block 1 and the lower limit block 2 to be directly fitted onto the outer sides of the flanges 7 on both sides of the unloading shut-off valve 6 pipeline during disassembly and assembly. The process is easy and stable, improving disassembly efficiency. The clearance adjusting pin 5 is used to fix the dust removal device 8, achieving a quick, secure, and stable connection.

[0019] The positioning hole on the upper limit block 1 is a through hole, the centering pin 4 is a nail-shaped structure, the pin diameter is equal to the bolt hole diameter of the feed shut-off valve 6 pipe flange 7, the length of the centering pin 4 is greater than or equal to 1.5 times the thickness of the upper limit block 1, the pin head of the centering pin 4 is a 30° cone, and the length of the pin head is equal to 0.5 times the thickness of the upper limit block 1.

[0020] In the above scheme, the centering pin 4 is a nail-shaped structure with a pin diameter equal to the diameter of the flange 7 bolt hole. The outer wall of the pin is smooth, allowing it to be freely and smoothly inserted and removed from the positioning hole of the limiting block. The length of the centering pin 4 is equal to 1.5 times the thickness of the upper limit block to ensure the concentricity of the positioning holes of the upper limit block 1 and the lower limit block 2 with the bolt hole of the pipe flange 7. At the same time, in order for the centering pin 4 to pass through the positioning hole and smoothly transition into the bolt hole of the pipe flange 7 during the centering insertion process, the head of the centering pin 4 is designed as a 30° conical structure with a length equal to 0.5 times the thickness of the upper limit block 1.

[0021] The positioning hole on the lower limit block 2 is a threaded hole, and the gap adjusting pin 5 is a single-headed hexagonal bolt structure. The end of the stud of the gap adjusting pin 5 is provided with a 45° chamfer with a length of more than 6mm. The stud length is greater than or equal to twice the thickness of the lower limit block 2. The thread of the gap adjusting pin 5 is engaged with the thread of the threaded hole of the lower limit block 2.

[0022] In the above scheme, the gap adjusting pin 5 is a single-headed hexagonal bolt structure. In order to smoothly transition into the bolt hole of the lower flange 7 of the pipe, the end of the stud has a 45° chamfer with a length of more than 6mm. The total length of the stud is greater than twice the thickness of the lower limit block. The thread specification matches the thread specification of the positioning hole of the lower limit block 2 to meet the needs of adjusting the gap between the lower limit block 2 and the pipe flange 7.

[0023] Both the upper limit block 1 and the lower limit block 2 are arc-shaped structures, and the arc length of the arc structure is greater than or equal to twice the distance between the two positioning holes. This design effectively improves the strength of the upper limit block 1 and the lower limit block 2, and makes the connection more stable and reliable.

[0024] Working principle: such as Figure 2As shown, before disassembling the feed shut-off valve 6, first remove the two adjacent pipe flange 7 fixing bolts 9 of the feed shut-off valve 6, take out the utility model, align the two positioning holes of the upper limit block with the two bolt holes on the pipe flange 7, and fix the limit block to the upper pipe flange 7 by fully inserting the centering pin 4, and then screw the two gap adjusting pins 5 into the threaded holes of the lower limit block 2 respectively, until the chamfered end of the stud of the gap adjusting pin 5 enters the bolt hole of the lower pipe flange 7, and the gap... The gap adjusting pin 5 will generate a stopping force on the lower flange 7 of the pipeline; the two diagonal bolts 9 of the two pipeline fixing bolts 9 that have been removed from the feed shut-off valve 6 will be removed again. Using the above method, another set of utility model products will be installed so that the other side of the pipeline flange 7 will also generate a stopping force. After the two sets of utility model products are installed, the other pipeline fixing bolts 9 can be removed. Under the action of the two sets of utility model products, the feed dust removal device 8 will be fixed and will not fall, thereby completing the disassembly of the feed shut-off valve 6.
