Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 7The utility model provides a technical solution: an auxiliary tool for installing a heat exchanger, comprising: a tubular shell 1 and a lifting platform 2, the lifting platform 2 is located below the tubular shell 1, a supporting unit is provided above the lifting platform 2, and the supporting unit comprises: a pair of inclined blocks 3, a pair of inclined blocks 3 are both located above the lifting platform 2, a plurality of first balls 4 are provided on the upper surface of the inclined blocks 3, the first balls 4 are in contact with the outer wall of the tubular shell 1, a cavity plate 5 is connected below the inclined blocks 3, an electric telescopic rod 6 is fixed to the top of the cavity plate 5, a cavity shell 7 is fixed to the top of the electric telescopic rod 6, a cylinder 8 is rotatably connected to the top of the cylinder 8, a U-shaped plate 9 is fixed to the top of the U-shaped plate 9, and a U-shaped plate 9 is fixed to the top of the cylinder 8. A roller 10 is provided above the plate 9, and the outer wall of the roller 10 is sleeved with an anti-slip sleeve 11. The front and rear ends of the roller 10 are connected with a round rod 12. The front surface of the U-shaped plate 9 is fixedly connected to a first motor 13, and the output shaft of the first motor 13 is fixedly connected to the round rod 12. The bottom end of the cylinder 8 is fixedly connected to a circular plate 14, and the upper surface of the circular plate 14 is fixedly connected to a gear ring 15. The upper side of the gear ring 15 is meshed with a tooth column 16, and the inner wall of the tooth column 16 is fixedly connected to a rotating rod 17. The rotating rod 17 is rotatably connected to the cavity shell 7 through a ball bearing. One end of the rotating rod 17 is fixedly connected to a second motor 18, and the second motor 18 is fixedly connected to the cavity shell 7. A control panel 19 is installed on one side of an inclined block 3.

[0027] In the specific implementation process, it is worth noting that the tubular shell 1 is the shell of the heat exchanger equipment, and the lifting platform 2 is composed of a base plate, a cylinder and a universal wheel structure with a self-locking function. Specifically, the four corners of the lower surface of the base plate are fixedly connected with a universal wheel with a self-locking function; the inner wall of the base plate is fixedly connected with a cylinder, the output end of the cylinder is fixedly connected to the cavity plate 5, and the air supply port of the cylinder is connected to the external air supply device through the air supply pipe to provide the required power source for the operation of the cylinder. The first ball 4 is composed of a groove seat and a ball. The groove seat is fixedly connected to the inclined block 3. The ball fits in the tubular shell 1, and the ball can be in the groove seat. The electric telescopic rod 6 is an electric drive device that converts electrical energy into mechanical energy to realize linear reciprocating motion. It is driven by a motor to convert rotary motion into linear motion. Common structures include motor, reducer, screw nut pair, guide rail, etc. When the motor rotates, the screw is driven to rotate by the reducer, and the nut moves along the screw in a straight line, thereby driving the push rod to extend and retract. By controlling the start, stop and direction of the motor, the telescopic length and speed of the push rod can be accurately adjusted. The power cord of the electric telescopic rod 6 is connected to the external power supply device to provide the required power for its operation. The cylinder 8 is connected to the electric power supply device by the roller. The ball bearing is rotatably connected to the cavity shell 7, and the anti-slip sleeve 11 is made of rubber material, which has a certain flexibility and a large surface friction resistance. This is because rubber is composed of long-chain polymers, and there are a large number of physical entanglement points between the molecular chains. When subjected to external forces, the molecular chains need to undergo a process of disentanglement, slippage, and re-entanglement. This dynamic process consumes a lot of energy and converts it into heat energy, resulting in a significant increase in energy dissipation friction resistance. In addition, there are micron-scale protrusions and nano-scale wrinkles on the rubber surface, which will form a multi-level contact structure with a real contact area far greater than the nominal contact area when in contact. This graded contact both enhances mechanical interlocking. The effect leads to uneven distribution of actual contact pressure, and local stress concentration causes adhesive friction. The round rod 12 is rotatably connected to the U-shaped plate 9 through a ball bearing. The casing of the first motor 13 is fixedly connected to the U-shaped plate 9. The power lines of the first motor 13, the second motor 18 and the third motor 29 are all connected to the external power supply device to provide them with the required electrical energy for operation. The casing of the second motor 18 is fixedly connected to the cavity shell 7. The connection lines of all electrical components in this application are connected to the external power supply device through the control panel 19, and the start and stop operations of all electrical components in the structure of this application can be controlled by the control panel 19.

[0028] Furthermore, the roller 10 is connected to the round rod 12 through a first connecting unit, and the first connecting unit includes: a pair of insertion rods 20, which are respectively fixed to the front and rear ends of the roller 10, and the insertion rods 20 are connected to the round rod 12 by plugging, and the insertion rods 20 are connected to the round rod 12 through fasteners 21.

[0029] During the specific implementation process, it is worth noting that a through groove for the insertion rod 20 is opened at the end of the round rod 12 close to the insertion rod 20, so that they can be plugged in. The fastener 21 is composed of a screw and a nut. Operating the fastener 21 can control whether the insertion rod 20 is connected to the round rod 12.

[0030] Furthermore, the anti-slip sleeve 11 is connected to the roller 10 through a second connecting unit, and the second connecting unit includes: two pairs of grooves 22, which are respectively opened at both ends of the outer wall of the anti-slip sleeve 11, and abutment plates 23 are provided inside the grooves. Bolts 24 are inserted into the surface of the butt plate 23, and the bolts 24 pass through the butt plate 23 and the anti-slip sleeve 11 in turn and are threadedly connected to the roller 10.

[0031] During the specific implementation process, it is worth noting that by rotating the bolt 24 counterclockwise to separate it from the roller 10, and removing the bolt 24 and the abutment plate 23, the anti-slip sleeve 11 can be stripped off the outer wall of the roller 10 and replaced with a new one, so that the tooling can operate stably for a long time.

[0032] Furthermore, a pair of second balls 25 are fixed to the lower surface of the U-shaped plate 9 , and the second balls 25 are in contact with the cavity shell 7 .

[0033] During the specific implementation process, it is worth noting that the second ball 25 is composed of a groove seat and a sphere. The groove seat is fixedly connected to the U-shaped plate 9, and the sphere is fitted with the cavity shell 7. The sphere can roll inside the groove seat but cannot be separated from the groove seat, which can reduce the burden on the connection between the cylinder 8 and the cavity shell 7.

[0034] Furthermore, the oblique block 3 is connected to the cavity plate 5 through an installation unit, and the installation unit includes: a pair of support blocks 26, a pair of support blocks 26 are respectively fixed to the bottom ends of a pair of oblique blocks 3, the support blocks 26 pass through a part of the cavity plate 5 through a transverse groove 27, the inner wall of the support block 26 is threadedly connected with a screw rod 28, the screw rod 28 is rotatably connected to the cavity plate 5 through a ball bearing, one end of the screw rod 28 is fixedly connected to a third motor 29, and the third motor 29 is fixedly connected to the cavity plate 5.

[0035] During the specific implementation process, it is worth noting that the support block 26 can move laterally inside the transverse groove 27, the screw rod 28 is a double-headed screw rod, the output shaft of the third motor 29 is fixedly connected to the screw rod 28, and the casing of the third motor 29 is fixedly connected to the cavity plate 5. The operator can drive the third motor 29 to rotate the screw rod 28. Since the threads on both sides of the outer wall of the screw rod 28 are set in opposite directions, when the output shaft of the third motor 29 rotates forward or reversely, the two support blocks 26 can be moved closer to or away from each other. In this way, the distance between the two inclined blocks 3 can be adjusted, so that the tooling can be adapted to use with tubular shells 1 of different outer diameters.

[0036] Furthermore, rollers 30 are fixed to the four corners of the lower surface of the inclined block 3 , and the rollers 30 are in contact with the cavity plate 5 .

[0037] During the specific implementation process, it is worth noting that the roller 30 is composed of a bracket and a wheel body. The wheel body is rotatably connected to the bracket through a pin shaft. The specific bracket is fixedly connected to the inclined block 3, and the wheel body is fitted with the cavity plate 5, which can play the effect of burdening the connection between the support block 26 and the screw rod 28.

[0038] Working principle:

[0039] Preparation before use:

[0040] First, move the lifting platform 2 to a suitable position in the installation area. The operator can drive the third motor 29 to rotate the screw rod 28. Since the threads on both sides of the outer wall of the screw rod 28 are set in opposite directions, when the output shaft of the third motor 29 rotates forward or reversely, the two support blocks 26 can be moved closer to or away from each other. In this way, the distance between the two inclined blocks 3 can be adjusted so that the distance between the two inclined blocks 3 meets the assembly requirements of the tubular shell 1.

[0041] Fine-tuning of the tubular shell position:

[0042] When the tubular shell 1 needs to be installed, first move the lifting platform 2 to a suitable position in the installation area, use the lifting tool to place the tubular shell 1 between the two inclined blocks 3, so that it fits with the first ball 4, then drive the lifting platform 2, adjust the height of the cavity plate 5, the inclined block 3 and the tubular shell 1, and lift the tubular shell 1 to a suitable height position. At this time, drive the second motor 18 to drive the rotating rod 17 and the tooth column 16 to rotate, and the tooth column 16 engages with the gear ring 15 for transmission, so that the gear ring 15, the circular plate 14, the cylinder 8, the U-shaped plate 9 and the roller 10 rotate 90° as a whole. Then, the operator starts the electric telescopic rod 6 to move the cavity shell 7, the U-shaped plate 9 and the roller 10 upward together. When the anti-slip sleeve 11 on the outer wall of the roller 10 fits and presses against the tubular shell 1, stop the operation of the electric telescopic rod 6, and then drive the first motor 13. By rotating the roller 10 and the anti-slip sleeve 11, the flange to be installed above the tubular shell 1 can be adjusted in the front-to-back direction. After completing the front-to-back position adjustment, the operator holds the flange to be installed above the tubular shell 1 with his hand and drives the electric telescopic rod 6 again to separate the anti-slip sleeve 11 from the tubular shell 1. Then, the second motor 18 is driven again to rotate the roller 10 90°. After that, the electric telescopic rod 6 is driven again to allow the anti-slip sleeve 11 to fit and press against the tubular shell 1 again. Finally, the first motor 13 is driven again to roll the roller 10 and the anti-slip sleeve 11, thereby fine-tuning the angle of the flange to be installed above the tubular shell 1 so that it is aligned with the flanges of other pipelines. This can not only support the tubular shell of the heat exchange equipment, but also adjust the position of the flange on the tubular shell more effortlessly. It does not require the hoisting personnel to work for a long time and can also improve the safety of the installation operation.

[0043] Maintenance of tooling wearing parts:

[0044] After long-term use, when the anti-slip sleeve 11 on the outer wall of the roller 10 is severely worn and the friction resistance of the outer wall is reduced to the point where it cannot meet the driving requirements of the tubular shell 1, the operator removes the fastener 21 and pulls out the plug 20 from the inside of the round rod 12, rotates the bolt 24 counterclockwise to separate it from the roller 10, and takes out the bolt 24 and the abutment plate 23. In this way, the anti-slip sleeve 11 can be stripped off the outer wall of the roller 10 and replaced with a new one. After the new anti-slip sleeve 11 is installed, the above-mentioned disassembled workpieces can be reset in sequence, which will be convenient for next use and ensure long-term and stable operation of the tooling.

[0045] Finishing work:

[0046] After the flange connection is installed, the upper support column is welded and fixed to the lower side of the outer wall of the tubular shell 1, and the bottom end of the support column is fixed to the ground to complete the overall installation of the tubular shell 1. Then drive the lifting platform 2 to move the inclined block downward, and finally pull out the entire workpiece for next use.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
