Description

Technical Field

[0001] The invention relates to the technical field of pipe assembly, and in particular to automatic assembly equipment for geothermal energy air ducts. Background Art

[0002] The ground source heat pump system is the most common geothermal energy application equipment, which mainly uses the relatively stable underground temperature to extract or discharge heat to provide heating services for buildings.

[0003] Ground source heat pump systems often need to be integrated with HVAC systems. When in use, fresh outdoor air needs to be introduced and preheated air needs to be transported, and the air needs to be transported through duct fittings.

[0004] In order to adapt to the use site and use path, it is essential to assemble multiple duct parts. When using existing technology to assemble multiple duct parts, the duct to be assembled is usually cleaned first, and it is determined that the duct parts are not damaged and the size is correct. Then the two ends of the duct are connected to the corner flange by rivets, and then the two adjacent corner flanges are connected by bolts, so as to realize the connection and assembly of the two ducts, and then repeat the bolt connection steps to realize the assembly of multiple ducts. However, in the process of connecting the duct by bolts, since multiple bolts need to be used for connection, the assembler needs to connect the multiple bolts in the multiple connection holes on the corner flange in turn, resulting in low efficiency of duct assembly, and the assembler needs to repeatedly move the duct to achieve precise positioning during assembly, thereby increasing the assembly operation steps and increasing the manpower investment.

The telescopic sections of the two third hydraulic push rods 361 drive the two rectangular frames 362 to move. The two rectangular frames 362 drive the four corresponding L-shaped rods 363 to move leftward. The L-shaped rods 363 drive the T-shaped cylindrical rod 355 to move until the vertical section of the T-shaped cylindrical rod 355 contacts the left side wall of the receiving tube 354. Then, the two third hydraulic push rods 361 are closed, and then a plurality of nuts used for assembly are sequentially placed in the plurality of receiving tubes 354 to fill the receiving tubes 354.

[0044] See also Figure 1 , Figure 2 , Figure 7 and Figure 8The geothermal energy air duct automatic assembly equipment also includes a docking device 4, which is provided with two and is symmetrically connected to the upper end of the base plate 1 front and back, and the docking device 4 includes a second support plate 41 installed on the upper end of the base plate 1 and located on the right side of the first support plate 32, and the second support plate 41 is penetrated by a second hydraulic push rod 42 near the upper end, and a second movable plate 43 is installed at one end of the second hydraulic push rod 42 close to the supporting mechanism 25, and a docking mechanism 44 is symmetrically connected to the end of the second movable plate 43 away from the second hydraulic push rod 42, and a limiting mechanism 45 connected to the second support plate 41 is provided on the left side of the second movable plate 43, and a supporting mechanism 46 is provided on the right side of the second movable plate 43.

[0046] Initially, the second hydraulic push rod 42 is connected to an external hydraulic pump. Before assembly, the four corresponding strip plates 443 are placed at corresponding positions on the two second support plates 41 according to the positions of the connecting holes at the corners of the duct corner flanges. Then, the four second connecting screws 442 are passed through the corresponding second circular holes 441 and threadedly connected to the corresponding strip plates 443, thereby installing the four strip plates 443 on the two second support plates 41.

[0047] See also Figure 5 , Figure 7 and Figure 8 The limiting mechanism 45 includes a T-shaped plate 451 fixedly connected to the end of the second supporting plate 41 close to the supporting mechanism 25, and the upper and lower ends of the vertical section of the T-shaped plate 451 are slidably connected with lifting rods 452.

[0048] During specific operation, the strip plate 443 drives the corresponding locking plate 453 to move through the two sliding grooves 445 when adjusting the position. The locking plate 453 slides in the vertical section of the T-shaped plate 451 through the lifting rod 452 to ensure that the locking opening 454 on the locking plate 453 is in the same position as the placement opening 444 on the strip plate 443.

[0049] See also Figure 1 , Figure 2 , Figure 5 and Fig. 9 The placing mechanism 46 includes a support rod 461 installed at the upper end of the rectangular slide rod 23, and two rectangular blocks 462 symmetrically distributed up and down are arranged above the support rod 461. The rectangular block 462 located at the bottom is detachably connected to the upper end of the support rod 461. A rectangular column 466 is installed at the upper end of the rectangular block 462 located at the bottom. A lifting frame 468 is slidably connected to the upper end of the rectangular column 466. The upper end of the lifting frame 468 is fixedly connected to the rectangular block 462 located at the top. The rectangular column 466 is provided with a plurality of evenly distributed from top to bottom. The cloth has positioning holes 467, and a positioning rod 469 is inserted into any one of the positioning holes 467. The positioning rod 469 is plugged into the lifting frame 468. A horizontally placed receiving tube 463 is installed through the middle of the rectangular block 462. The inner hole cross-section of the receiving tube 463 is consistent with the head shape of the bolt used for assembly. A T-shaped pushing rod 464 is slidably penetrated and connected to the right side wall of the receiving tube 463. The vertical section of the T-shaped pushing rod 464 is located inside the receiving tube 463 and a connecting spring 465 is installed between the right side wall of the receiving tube 463.

[0050] Initially, the rectangular block 462 at the bottom is in a separated state from the support rod 461. Before assembly, during the adjustment of the two rectangular slide bars 23, the rectangular slide bars 23 drive the support rod 461 to move at the same time, and the two lifting frames 468 are slid according to the positions of the connecting holes at the corners of the duct flanges. The lifting frames 468 drive the rectangular block 462 and the receiving tube 463 at the top to move. When the lifting frames 468 slide to the desired position on the positioning rods 469, the positioning rods 469 are inserted through the lifting frames 468 and matched with the corresponding positioning holes 467 to realize the function of limiting the rectangular block 462 at the top, ensuring that the two receiving tubes 463 are in a stable state. 63 is consistent with the distance between the upper and lower connecting holes of the corner flange, and then the four T-shaped pushing rods 464 are pulled in turn, the vertical section of the T-shaped pushing rod 464 slides in the receiving tube 463 and squeezes the connecting spring 465, and then the multiple bolts required for assembly are placed in the four receiving tubes 463 in turn and the receiving tubes 463 are filled, and then the filled receiving tubes 463 are placed on the upper end of the support rod 461, and then the two rectangular blocks 462 located below are respectively installed on the support rod 461. At this time, the left ends of the four receiving tubes 463 are tightly attached to the four strip plates 443, and the strip plates 443 block and limit the bolts in the receiving tubes 463.

[0051] See also Figure 1 , Figure 5 , Figure 7 and Figure 8 The docking mechanism 44 also includes two sliding rails 446 symmetrically installed on the right end of the strip plate 443 through a mounting block.

The opening of the limit plate 447 faces the second movable plate 43. Reset springs 448 are installed between the two ends of the opening of the limit plate 447 and the two mounting blocks respectively. A baffle 449 is hinged at one end of the limit plate 447 away from the second movable plate 43.

[0052] After the four receiving tubes 463 are installed and positioned, the two second hydraulic push rods 42 are started at the same time. The second hydraulic push rods 42 drive the two strip plates 443 to move away from the supporting mechanism 25 through the second moving plate 43. The strip plates 443 drive the limit plates 447 to move toward the receiving tubes 463 through the two slide rails 446 and the two return springs 448. After the strip plates 443 continue to move and drive the middle section of the limit plates 447 to contact the receiving tubes 463, the receiving tubes 463 block the limit plates 447, so that the strip plates 443 and the limit plates 447 are relatively displaced until the placement opening of the strip plates 443 is reached. 444 moves to the opening of the receiving tube 463. At this time, the second hydraulic push rod 42 is closed, and the squeezed connecting spring 465 drives the T-shaped pushing rod 464 to push the multiple bolts. After the multiple bolts are forced, they move toward the placement opening 444, and the bolt on the far left moves out of the receiving tube 463 until the head of the far left bolt moves into the placement opening 444. The placement opening 444 holds the head of the bolt, and the screw rod of the bolt moves into the sliding groove 445 of the positioning plate 453. The positioning plate 453 limits and blocks the head of the far left bolt to ensure that the head of the bolt can accurately enter the placement opening 444.

[0053] See also Figure 1 , Figure 2 and Figure 5 The supporting mechanism 25 includes two supporting columns 251 symmetrically installed on the upper end of the rectangular sliding rod 23, and a right-angle plate 252 is installed on the upper end of the supporting column 251. Two alignment rods 253 are commonly installed on the two right-angle plates 252, and the two alignment rods 253 are respectively fixedly connected to the horizontal section and the vertical section of the right-angle plate 252.

[0054] Initially, the sealing pad required for assembly is clamped on any end of the air duct. During assembly, the multiple air ducts to be assembled are placed in the space formed by the four alignment rods 253 in sequence (see Fig.10), when placing the air duct, the end with the sealing gasket faces left, the two calibration rods 253 at the bottom support the multiple air ducts, and the two calibration rods 253 at the top limit and guide the multiple air ducts, so as to realize the function of automatic and precise alignment of the multiple air ducts, and sequentially place the multiple air ducts between the four calibration rods 253 and move from left to right, when the corner flange at the right end of the right air duct moves over the strip plate 443, start the two second hydraulic push rods 42, the second hydraulic push rods 42 drive the two strip plates 443 to move toward the air duct through the second moving plate 43, the placement opening 444 on the strip plate 443 drives the bolt to move toward the air duct, the baffle 449 on the limiting plate 447 limits the head of the bolt to prevent the bolt from separating from the placement opening 444 when the strip plate 443 moves, and when the four strip plates 443 move, the two second hydraulic push rods 42 drive the two strip plates 443 to move toward the air duct, and the baffle 449 on the limiting plate 447 limits the head of the bolt to prevent the bolt from separating from the placement opening 444 when the strip plate 443 moves. After the plate 443 drives the four bolts to move between the two corner flanges at the left and right ends of the air duct, the two second hydraulic push rods 42 are closed, and the air duct on the right side continues to move. The air duct on the right side drives the four connecting holes on the corner flange at the left end to be sleeved on the four bolts. At the same time, the four strip plates 443 block the corner flange at the left end of the air duct on the right side to realize the function of limiting the air duct on the right side. In the process of the four connecting holes on the corner flange being sleeved on the four bolts, the limiting plate 447 blocks the right end of the bolt head to prevent the bolt from falling off. When the air duct on the right side contacts the strip plate 443, the adjacent air duct continues to move and fits tightly with the air duct on the right side, and the four connecting holes on the corner flange at the right end of the adjacent air duct are sleeved on the four bolts to realize the preliminary connection of the two adjacent air ducts.

[0055] See also Figure 1 and Figure 6 The tightening mechanism 35 also includes a first pulley 356 installed on the outer ring surface of the receiving tube 354, a driving motor 357 is installed on the rectangular plate 353, and a second pulley 358 is installed on the output shaft of the driving motor 357. The second pulley 358 is connected to the first pulley 356 by a belt.

[0056] Initially, the driving motor 357 is connected to an external power source. After the two adjacent air ducts are preliminarily connected, the two first hydraulic push rods 33 are started. The two first hydraulic push rods 33 drive the four rectangular plates 353 to move toward the air duct direction through the two first moving plates 34. The rectangular plates 353 drive the receiving tube 354 to move. When the receiving tube 354 moves to the axial position of the corner flange connecting hole, the two first hydraulic push rods 33 are closed, and then the electric slider 312 is started. The electric slider 312 drives the first hydraulic push rod 33 to move through the first supporting plate 32. The first hydraulic push rod 33 drives the rectangular plate 353 to move through the first moving plate 34. The rectangular plate 353 drives the nut to move toward the corresponding bolt through the receiving tube 354 ... After the nut at the right end of the cylinder 354 contacts the bolt, the drive motor 357 is started. The drive motor 357 is a low-speed motor. The drive motor 357 drives the second pulley 358 to rotate. The second pulley 358 drives the first pulley 356 to rotate through the belt. The first pulley 356 drives the receiving cylinder 354 to rotate. The receiving cylinder 354 drives the nut to rotate and is threadedly connected with the corresponding bolt. The length of the bolt's screw rod exceeding the two corner flanges is consistent with the thickness of the nut until the nut is tightened to the corner flange of the air duct and fits tightly therewith, thereby realizing the function of assembling and connecting the two air ducts, and four bolts are connected at the same time, which effectively improves the efficiency of the air duct assembly. There is no need for the assemblers to repeatedly perform bolt connection operations, reducing manpower investment.

[0057] Turn off the driving motor 357, the electric slider 312 drives the first hydraulic push rod 33 to reset through the first support plate 32, the first hydraulic push rod 33 drives the rectangular plate 353 to move through the first movable plate 34, the rectangular plate 353 drives the receiving tube 354 to reset, start the first hydraulic push rod 33 again, the first hydraulic push rod 33 drives the rectangular plate 353 to reset through the first movable plate 34, then start the third hydraulic push rod 361, the third hydraulic push rod 361 drives the L-shaped rod 363 to move through the rectangular frame 362, the L-shaped rod 363 drives the corresponding T-shaped cylindrical rod 355 to push multiple nuts until the nuts move to the end of the receiving tube 354, and then turn off the third hydraulic push rod 361.

[0058] Start the two second hydraulic push rods 42 again. The two second hydraulic push rods 42 drive the four strip plates 443 to reset through the two second movable plates 43. The four bolts are separated from the corresponding placement openings 444. The previous steps of automatic bolt loading are repeated. At this time, the four strip plates 443 release the limit on the air ducts. Push multiple air ducts again and push the next air duct to the four strip plates 443. Repeat the previous steps of assembling and connecting the two air ducts until all the multiple air ducts that need to be assembled are assembled.
