Specific embodiment
The utility model is not limited by following embodiments, can technical solution according to the present utility model and actual conditions Determine specific embodiment.
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to specification The Butut mode of attached drawing 1 is described, such as: front, rear, top, and bottom, left and right positional relationship be according to Figure of description Butut direction determine.
The utility model is further described below with reference to examples and drawings:
As shown in attached drawing 1,2,3, which includes rack 1, connection frame, connector and wirerope 12, machine 1 left part of frame is fixed with two connectors that can adjust upper-lower height along the longitudinal direction, connection frame is equipped with above rack 1, even Connecing frame includes locating rod 15 and two fixed links 4 being spaced apart along the longitudinal direction, each fixed link 4 with corresponding connector It is fixed together, locating rod 15 is located at the left part of two fixed links 4 and is fixed together the two, outside locating rod 15 Lateral edge front-rear direction is equipped at least one chain block 11, and the suspension hook of each chain block 11 is respectively connected with wirerope 12.
When operation, the upper-lower height of adjusting connector makes it meet job requirements, and heat exchanger by the right part of fixed link 4 Shell flange 5 is fixed together, while one end of wirerope 12 and heat exchanger water cooling core 10 being fixed together.By It being fixed together in connection frame and shell flange 5, the two is fixed, when operating the pulling wirerope 12 of chain block 11, It is moved to the left water cooling core 10 relative to shell flange 5, and then water cooling core 10 is extracted out from heat exchanger, complete heat exchanger core pulling Operation.The utility model and heat exchanger shell flange 5 are fixed together by the setting of connection frame, and chain block 11 and locating rod 15 are fixed together, and when operating the pulling wirerope 12 of chain block 11, make shell flange 5 by thrust to the right, water cooling core 10 by pulling force to the left, and then makes that core pulling operation is more laborsaving, improves operating efficiency.In addition, respectively by connection frame and cylinder Body flange 5, bottle gouard moved by hands and fixed frame, which link together, to be also avoided in operation process wirerope 12 and occurs swinging to lead to water The phenomenon that cold core 10 glances off when extracting out, resistance increases, also makes the utility model operation more stable, improves its operation Safety reduces operation consumption.It is full with this that the setting of connector can need to adjust the upper-lower height of connection frame according to operation The job requirements of sufficient different height heat exchanger core pulling.In addition, the utility model does not need other Large-scale Hoistings in operation process Less important work is carried out, and its is compact-sized, and smaller, using flexible, conveniently is influenced by working space limitation.According to need It wants, fixed link 4 can be fixed together by U-shaped card part or bolt or steel wire with shell flange 5;Wirerope 12 and water cooling core 10 tube sheets are fixed together.
Above-mentioned heat exchanger core-pulling device can be made further optimization and/or improvements according to actual needs:
As shown in attached drawing 1,2,3, each connector includes locating piece 14, adjusts screw rod 2 and adjusting nut 3, adjusts silk 2 lower part of bar is fixed together with rack 1, is adjusted 2 top of screw rod set and is respectively arranged with locating piece 14, corresponding 14 lower section of locating piece The adjusting nut 3 that limitation locating piece 14 moves down is respectively connected on the outside of the adjusting screw rod 2 of position, each 14 left part of locating piece is equal It links together with corresponding 4 left part of fixed link.It is moved down since adjusting nut 3 can limit locating piece 14, when needs pair When the upper-lower height of connection frame is adjusted, turn adjusting nut 3 and then the adjustment for realizing connection frame upper-lower height.Thus can make The utility model meets the job requirements of different height heat exchanger core pulling.Meanwhile it can also be by adjusting the operation height of connection frame The angle the drive of water cooling core 10 is adjusted, guarantees that water cooling core 10 horizontal can extract that (water cooling core 10 is pacified with it during extraction out Fill hole and keep concentric), it avoids making due to 10 deflection of water cooling core operation resistance when its extraction from increasing, causes operation consumption increased existing As occurring.
As shown in attached drawing 1,2,1 top of rack is equipped with the rolling bar 6 that at least one is in front-rear direction arrangement, rolling in left-right direction The front of thick stick 6 links together with rack 1 respectively with rear portion, and rolling bar 6 being capable of rotation.When water cooling core 10 extracts a part out, water Cold core 10 is placed on 1 top of rack and extracts out to the left under the action of rolling bar 6, since the setting of rolling bar 6 makes water cooling core 10 Sliding friction between rack 1 is converted to rolling friction, effectively reduces the operation resistance of the extraction of water cooling core 10, makes core pulling Operation is time saving and energy saving, reduces operation consumption.
As shown in attached drawing 1,3, the front and rear of rack 1 is equipped at least two support frames 7, Mei Gezhi in left-right direction 7 top of support is fixed together with rack 1, and the lower outside of each support frame 7 is set with abutment sleeve 8, corresponding each Jack 9 is equipped on the inside of the corresponding abutment sleeve 8 of 7 bottom position of support frame, each 9 top of jack is against correspondence respectively 7 bottom of support frame.The upper-lower height of rack 1 is adjusted by setting jack 9, and then enables rack 1 to the water cooling of extraction Core 10 plays the role of lifting support, improves the adaptability of the utility model operation.Meanwhile rack 1 is carried out by jack 9 Height adjustment it is time saving and energy saving, improve operating efficiency.In addition, being set with abutment sleeve 8 also in 7 lower outside of support frame makes Its operation when highly adjusting to rack 1 is more stable.
As shown in attached drawing 1,3, it is fixedly connected to along the longitudinal direction or/and between the adjacent abutment sleeve 8 of left and right directions Reinforcing rod 13.The mechanical strength for effectively improving the utility model guarantees the reliability of its operation.
As shown in attached drawing 1,2, the outside of locating rod 15 sets that there are two chain block 11 and its operating speeds along the longitudinal direction Unanimously.Thus it can make water cooling core 10 in extraction by uniform pulling force, and then prevent water cooling core 10 in core pulling operation process There is the phenomenon that deflection causes operation resistance to increase.
The above technical characteristic constitutes the most preferred embodiment of the utility model, with stronger adaptability and best implementation Effect can increase and decrease non-essential technical characteristic, according to actual needs to meet the needs of different situations.
