Description

Technical Field

[0001] The utility model relates to the technical field of maintenance tooling, in particular to an innovative core-pulling maintenance tooling for heat exchangers. Background Technique

[0002] Heat exchangers are commonly used equipment in life, mainly used to transfer heat from one medium to another. After long-term use, various impurities and dirt will accumulate inside the heat exchanger, seriously affecting the heat transfer efficiency of the heat exchanger and even causing heat exchanger failures. The role of core-pulling is to remove substances such as dirt, corrosion products, and rust blocked in the core tube, clean the internal deposits, so that the inside of the heat exchanger can be thoroughly cleaned to ensure the normal operation of the heat exchanger. However, during the core-pulling process, dirt and other sundries fall on the bottom surface or the machine as the heat exchanger core is pulled out, resulting in very troublesome subsequent cleaning.

[0003] Therefore, an innovative core-pulling maintenance tooling for heat exchangers is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defect that dirt falls randomly during the core-pulling process in the prior art, and an innovative core-pulling maintenance tooling for heat exchangers is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An innovative core-pulling maintenance tooling for heat exchangers includes a bottom plate. Two groups of C-shaped plates are fixedly installed on the top of the bottom plate. The same cross plate is slidably installed on the mutually close sides of the two groups of C-shaped plates. Two positioning plates are fixedly installed on the top of the cross plate. A plurality of groups of rollers are rotatably installed on the mutually close sides of the positioning plates. A storage box is slidably installed on the bottom of the cross plate. A clamping plate is rotatably installed on the side of the cross plate;

[0007] A support frame is arranged on one side of the bottom plate, and a heat exchanger is installed inside the support frame;

[0008] A support block is installed on the surface of the bottom plate. A winch is fixedly installed inside the support block, and a steel wire rope is arranged on the outer wall of the rotating shaft of the winch.

[0009] In a possible design, two positioning blocks are fixedly connected to the surface of the bottom plate. A lead screw is rotatably connected between the tops of the two positioning blocks and the two C-shaped plates respectively. Fixing blocks are threadedly connected to the circumference of the lead screw, and the fixing blocks are all fixed to the cross plate. A connecting rod is rotatably connected between the two positioning blocks. Two first bevel gears are fixedly connected to the circumference of the connecting rod. Second bevel gears are fixedly connected to the bottoms of the lead screws respectively. The first bevel gears are meshed with the second bevel gears respectively. A first motor is fixedly connected to one side of one of the positioning blocks. The output shaft of the first motor penetrates the positioning block and is fixedly installed with a third bevel gear, and the third bevel gear is meshed with one of the second bevel gears.

[0010] In a possible design, a handle is fixedly installed on the side of the storage box for pulling the storage box to slide on the bottom surface of the cross plate. A water outlet penetrating the storage box is arranged at the bottom of the storage box. An end cover is threadedly connected to the outer wall of the water outlet for controlling the discharge of waste water inside the storage box.

[0011] In a possible design, grooves are arranged at the four corners of the bottom of the bottom plate. An electric push rod is fixedly installed inside the groove. A universal wheel is fixedly installed at the output end of the electric push rod. A push handle is fixedly installed on the side of the bottom plate for pushing the bottom plate to move.

[0012] In a possible design, a through groove is arranged on the outer side of the support block, and a pulley block is fixedly installed on the outer side of the support block. The through groove and the pulley block are used in cooperation with a steel wire rope.

[0013] In this application, the device is pushed to the front of the support frame through the push handle, and the device is adjusted to a suitable position. The heat exchanger is fixed by the clamping plate. After the fixing is completed, the steel wire rope on the outer wall of the winch is taken out, and the steel wire rope is passed through the pulley block along the through groove, and finally sleeved on the ear plate of the inner core of the heat exchanger. The second motor is started, and the rotating shaft of the winch is driven by the second motor to rotate. While rotating, the steel wire rope is tightened to drag the inner core of the heat exchanger. The dragged inner core moves along the roller. While moving, the liquid impurities inside the inner core fall into the storage box and slide down to the bottom of the storage box for unified collection. If the position of the heat exchanger to be cored is too high, the first motor is started. The first motor rotates to drive the bevel gears inside the positioning block to mesh. One of the bevel gears drives the lead screw to rotate. The fixing block on the outer wall of the lead screw drives the cross plate to rise. Stop when reaching the specified position, and continue to drag the inner core through the steel wire rope.

[0014] Beneficial effects:

[0015] In the present utility model, for the innovative heat exchanger core-pulling maintenance tooling, the horizontal plate is slidably connected to the storage box. While dragging the core body, liquid impurities and the like slide to the bottom of the storage box. When the inspection and maintenance of the heat exchanger are completed, the device is pushed to move, and the storage box is pulled out through the handle on the side of the storage box. The end cover is rotated to uniformly collect and process the impurities inside the storage box, and it is convenient for cleaning;

[0016] In the present utility model, for the innovative heat exchanger core-pulling maintenance tooling, the fixing block on the outer wall of the screw rod is fixedly connected to the horizontal plate. The rotation of the screw rod drives the fixing block to rise, and the fixing block drives the horizontal plate to rise, so as to perform core-pulling maintenance on heat exchangers of different heights.
