It will be appreciated that the jaws 43 are provided in pairs, and that pairs of jaws 43 may be provided in the height direction (i.e. up and down direction) to enable a more secure connection of the push beam 4 to the heat exchanger tube bundle 10.
The suspension bolts 44 are provided at both ends of the main beam portion 41 in a direction perpendicular to the insertion direction.

Specifically, the rope 64 is bifurcated, i.e., the rope 64 includes a first rope 641 and a second rope 642, the first rope 641 being drawn from one side (e.g., the upper side) of the hoist 61, the second rope 642 being drawn from the other side (e.g., the lower side) of the hoist 61, such that when the first rope 641 is drawn from the hoist 61, the second rope 642 is reeled in, and vice versa.
As shown in fig. 3 and 4, the first rope 641 is led out from the winding machine 61, passes through three fixed pulleys 621 of the fixed pulley group 62 and one movable pulley 631 of the movable pulley group 63 (fixedly mounted on the push beam 4) in sequence, and is then fixedly mounted on the integrated frame 7. The second rope 642 is led out from the winch 61, passes through two fixed pulleys 621 of the fixed pulley block 62 and one movable pulley 631 of the movable pulley block 63 (fixedly installed on the push beam 4) in sequence, and is then fixedly installed on the whole frame 7. The fixed ends of the first rope 641 and the entire frame 7 and the fixed ends of the second rope 642 and the entire frame 7 are respectively located at two sides of the entire frame 7 in the penetrating direction and at two sides of the heat exchanger tube bundle 10.
In the present embodiment, when the pushing beam 4 is fixedly mounted on the heat exchanger tube bundle 10 on the supporting trolley 2, the winch 61 rotates in a predetermined direction (for example, rotates in a forward direction), and the pushing beam 4 with the heat exchanger tube bundle 10 can be driven by the first rope 641 to move toward the barrel 20 in the penetrating direction, in the process, the first rope 641 is reeled in, and the second rope 642 is reeled out; the hoist 61 is rotated in a direction opposite to the predetermined direction (e.g., counter-rotated), and the push beam 4 can be driven by the second rope 642 in a threading direction away from the drum 20 with the heat exchanger tube bundle 10, during which the first rope 641 is paid out and the second rope 642 is paid in.
In the present embodiment, the winding machine 61, the fixed pulley block 62, the movable pulley block 63, and the rope 64 in the driving mechanism 6 may have two sets, and the two sets may be provided at intervals in a direction perpendicular to the threading direction. It can be understood that two sets of movable pulley blocks 63 are respectively arranged on the pulley mounting portions 42 at both ends of the pushing beam 4.
In the present embodiment, as shown in fig. 3 and 4, the entire frame 7 includes a base 71, a left upright 72, and a right upright 73. The left upright 72 is connected to the right upright 73 via the base 71.
The base 71 has a substantially rectangular shape as a whole. The support frame 11 is integrally connected to the base 71 through a connecting plate 111, and a part of the winch 61 and the fixed pulley block 62 is also disposed on the base 71. Thus, the whole migration of the penetrating tool is facilitated.
The left upright 72 is disposed at the left end of the base 71, the first rope 641 passes through the movable pulley 631 of the push beam 4 and is fixed to the left upright 72, and the last fixed pulley 621 through which the first rope 641 passes is disposed on the left upright 72.
The right upright 73 is provided at the right end of the base 71, and the second rope 642 is fixed to the right upright 73 after passing through the movable pulley 631 on the push beam 4.
Reinforcing rib plates 74 can be arranged between the left upright post 72 and the base 71, and between the right upright post 73 and the base 71, so that the structural strength of the integral frame 7 can be enhanced.
It should be understood that the left post 72 may be unitary (as shown in fig. 3), or may be separate. Likewise, the right upright 73 may be integral, or may be separate (as shown in fig. 3).
In the present embodiment, as shown in fig. 1, 2, and 7, the cylindrical body center adjustment mechanism 8 includes two sets of roller support mechanisms that are provided at intervals in the piercing direction for supporting the cylindrical body 20.
Each set of roller support mechanism includes two roller support portions 81, and the two roller support portions 81 are disposed opposite to each other in a direction perpendicular to the penetrating direction. The roller supporting portion 81 includes a supporting roller 811 and a height adjusting mechanism including a supporting base 812, a first fixing base 813, a second fixing base 814, and a telescopic cylinder 815 (e.g., a hydraulic cylinder or an air cylinder).
The supporting roller 811 can be rotatably disposed on the supporting base 812 relative to the supporting base 812, two ends of the supporting base 812 are rotatably connected to the first fixing base 813 and the telescopic cylinder 815 respectively, and one end of the telescopic cylinder 815 departing from the supporting base 812 is rotatably connected to the second fixing base 814. The first fixing seat 813 and the second fixing seat 814 are fixed on the ground or other structures.
In the present embodiment, as shown in fig. 7, the simultaneous extension of the two telescopic cylinders 815 can increase the height of the cylinder 20, the simultaneous contraction of the two telescopic cylinders 815 can decrease the height of the cylinder 20, the extension of the front telescopic cylinder 815 (i.e., the left side in fig. 7) or the contraction of the rear telescopic cylinder 815 (i.e., the right side in fig. 7) can move the cylinder 20 backward, and the extension of the rear telescopic cylinder 815 or the contraction of the front telescopic cylinder 815 can move the cylinder 20 forward. That is, the telescoping of the telescoping cylinder 815 can adjust the central axis position of the barrel 20 such that the central axis of the barrel 20 is aligned with the central axis of the heat exchanger tube bundle 10. This also enables the inventive piercing tooling to accommodate heat exchanger tube bundles 10 of different specifications.
In the present embodiment, as shown in fig. 1 and 2, the stopper mechanism 9 includes a stopper plate 91 and a stopper rope 92. The limit plate 91 is connected with the left upright 72 in the integral frame 7 through a limit pull rope 92.
The limiting plate 91 is used for axially limiting the cylinder 20. That is, when the barrel 20 and the heat exchanger tube bundle 10 are installed in place, the limiting plate 91 is disposed at one end of the barrel 20 away from the heat exchanger tube bundle 10 (or the heat exchanger tube bundle supporting mechanism 1), and the plate surface of the limiting plate 91 abuts against the barrel 20 under the action of the limiting pull rope 92. Thus, when the heat exchanger tube bundle 10 moves into the barrel 20, the barrel 20 does not move in the axial direction due to the friction force applied by the heat exchanger tube bundle 10, and the heat exchanger tube bundle 10 can accurately and smoothly enter the barrel 20.
The following describes a method of inserting a heat exchanger tube bundle in the insertion tool according to the present invention.
In this embodiment, referring to fig. 1 and 2, when the heat exchanger tube bundle 10 needs to be threaded into the cylinder 20, the chain transmission mechanism 3 can be moved by the manual crank, the spacing between the support trolleys 2 is adjusted to match the spacing between the baffles 101 on the heat exchanger tube bundle 10 to be threaded, and finally the support trolleys 2 stay at the proper positions. Then, the heat exchanger tube bundle 10 is lifted (may be lifted by a crane or the like) onto the bundle support mechanism 1, and the heat exchanger tube bundle 10 is supported by the support trolley 2.
The barrel 20 is lifted to the barrel center adjusting mechanism 8, and the central axis position of the barrel 20 is adjusted by the barrel center adjusting mechanism 8, so that the central axis of the barrel 20 is aligned with the central axis of the heat exchanger tube bundle 10.
The hoisting mechanism 5 moves the push beam 4 to a proper position (preset position), the push beam 4 is fixedly arranged on the heat exchanger tube bundle 10, and then the hoisting mechanism 5 is separated from the push beam 4. Threading cord 64. The limit mechanism 9 is installed so that the limit plate 91 abuts on one end of the cylinder 20.
The hoist 61 rotates in a predetermined direction, and the push beam 4 and the heat exchanger tube bundle 10 are moved together in the predetermined direction toward the drum 20 by the first rope 641, so that the heat exchanger tube bundle 10 finally enters the drum 20. It will be appreciated that during this process, the support carriages 2 move with the drive chains 31, the support carriages 2 being separated one by one from the baffles 101 and finally from the heat exchanger tube bundle 10.
It will be appreciated that the threading of the heat exchanger tube bundle 10 need not be performed exactly as described above, and that some of the processes may be performed simultaneously or in an alternate sequence, as may be practical. For example, the can 20 can be lifted first, followed by the heat exchanger tube bundle 10. For another example, the stopper plate 91 may be installed, and then the push beam 4 and the reeving rope 64 may be installed.
When it is desired to withdraw the heat exchanger tube bundle 10 from the drum 20, it is likewise desired to fixedly mount the push beam 4 on the heat exchanger tube bundle 10, adjust the chain drive 3 so that the support trolley 2 is in position, thread the rope 64, rotate the hoist 61 in the direction opposite to the predetermined direction, carry the push beam 4 together with the heat exchanger tube bundle 10 away from the drum 20 in the predetermined direction by means of the second rope 642, and finally withdraw the heat exchanger tube bundle 10 from the drum 20. It will be appreciated that in the process, the baffles 101 of the heat exchanger bundle 10 will snap-fit one by one with the plurality of support trolleys 2, the support trolleys 2 moving with the heat exchanger bundle 10 (also with the movement of the drive chains 31), and finally the heat exchanger bundle 10 completely extracted being supported by the plurality of support trolleys 2.
By adopting the technical scheme, the penetrating tool for the heat exchanger tube bundle disclosed by the invention at least has the following advantages:
(1) the penetrating tool for the heat exchanger tube bundle comprises a tube bundle supporting mechanism and a supporting trolley, wherein the tube bundle supporting mechanism and the supporting trolley are used for supporting the heat exchanger tube bundle, the pushing cross beam is used for being fixedly connected with the heat exchanger tube bundle, and the driving mechanism is used for driving the pushing cross beam and the heat exchanger tube bundle to reciprocate along the penetrating direction.
