Description

Technical Field

[0001] The utility model relates to the field of a multi-directional motion positioning mechanism for a three-gun cleaning machine, in particular to a multi-directional motion positioning mechanism for a three-gun cleaning machine. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. Due to the long-term operation of the heat exchanger, the different purity levels of the cooling or heating sides and the differences in the properties of the process media themselves have led to inevitable scaling of the heat exchanger, resulting in a decrease in the heat exchange efficiency of the heat exchanger, thereby affecting the normal production and the safety of the equipment. Therefore, the heat exchanger should be cleaned regularly to remove dirt to ensure high heat exchange of the heat exchanger and normal production.

[0003] The three-gun cleaning machine is a common device used to clean heat exchangers. It is installed on a crossbeam. The motor enables the cleaning machine to move in multiple directions on the cross frame so that the muzzle is aligned with the pipe mouth of the heat exchanger, and the internal hose is used to move for cleaning. The traditional cross frame needs to be fixed on the surface of the heat exchanger for use. The Chinese patent with patent number CN 202021057462.4 discloses a main crossbeam structure for a three-gun cleaning machine for a heat exchanger. Since the three-gun cleaning machine is installed on the outside of the cross frame, the overall center of gravity is unstable, affecting stability. Utility Model Content

[0004] The main purpose of the utility model is to provide a multi-directional motion positioning mechanism for a three-gun cleaning machine, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a multi-directional motion positioning mechanism for a three-gun cleaning machine, comprising two supporting beams and two cross beams, the two ends of the two cross beams are respectively installed on the surfaces of the two supporting beams, the surfaces of the two cross beams are installed with first clamping wheels, a vertical beam is installed between the two first clamping wheels, the surface of the vertical beam is installed with a second clamping wheel, the surface of the second clamping wheel is installed with a three-gun cleaning machine body, and an eccentric rod is fixedly installed at the bottom of the two supporting beams, and the orientation direction of the eccentric rod is consistent with the installation orientation of the three-gun cleaning machine body.

[0006] The surface of the support beam is provided with a plurality of through grooves, which are longitudinally arranged linearly on the surface of the support beam. Two protrusions are fixedly installed on the surface of the cross beam, and the two protrusions are respectively stuck in the through grooves of the two support beams, and a connecting component is installed between the protrusions and the inside of the through grooves.

[0007] The connection assembly comprises a thread groove, which is arranged on the surface of the protrusion. A bolt is installed inside the thread groove, and the head of the bolt is against the surface of the support beam.

[0008] The surface of the support beam is provided with a transverse groove, the surface of the transverse beam is fixedly mounted with a limit block, the protrusion is fixed on the surface of the limit block, and the limit block is clamped in the transverse groove.

[0009] The eccentric rod and the support beam are an integrated structure.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. In the utility model, by arranging a support beam, a cross beam and an eccentric rod, the center of gravity of the bracket composed of the support beam and the cross beam is located in the plane of the bracket. Since the three-gun cleaning machine body is installed on one side of the cross beam, the overall center of gravity is offset. Therefore, the center of gravity keeps moving during the movement, which will cause the installation of the support beam and the cross beam to be unstable. However, the eccentric rod has a certain support for the support beam, so it can ensure the stability of the three-gun cleaning machine body when moving.

[0012] 2. In the utility model, by setting the crossbeam, threaded groove and bolts, the distance between the two crossbeams is constant, and the three-gun cleaning machine body can only move longitudinally within this range. However, for different heat exchangers, the height is different. Therefore, it is necessary to change the moving range of the three-gun cleaning machine body, remove the bolts from the inside of the threaded groove, install them to the inside of the new through groove, and then fix the bolts. At this time, the position of the crossbeam can be replaced to adapt to different heat exchangers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, a multi-directional motion positioning mechanism for a three-gun cleaning machine includes two support beams 1 and two cross beams 2. The support beam 1 is placed longitudinally and the cross beam 2 is placed transversely. The two ends of the two cross beams 2 are respectively installed on the surfaces of the two support beams 1, so that the two support beams 1 and the two cross beams 2 form a rectangular shape to ensure the overall external frame. The surfaces of the two cross beams 2 are installed with first clamping wheels 3, and the first clamping wheels 3 can move transversely on the surfaces of the cross beams 2. A vertical beam 4 is installed between the two first clamping wheels 3. The surface of the vertical beam 4 is installed with a second clamping wheel 5, and the second clamping wheel 5 can move longitudinally on the surface of the vertical beam 4. The surface of the second clamping wheel 5 is installed with a three-gun cleaning machine body 6. An eccentric rod 7 is fixedly installed at the bottom of the two support beams 1. The eccentric rod 7 and the support beam 1 form an L-shaped structure. The orientation direction of the eccentric rod 7 is consistent with the installation orientation of the three-gun cleaning machine body 6.

[0020] The center of gravity of the bracket composed of the support beam 1 and the cross beam 2 is located in the plane of the bracket. Since the three-gun cleaning machine body 6 is installed on one side of the cross beam 2, the overall center of gravity will be shifted and moved to the outside of the bracket. At this time, the center of gravity of the three-gun cleaning machine body 6 will continue to move during the movement, which will cause the installation of the support beam 1 and the cross beam 2 to be unstable. However, the eccentric rod 7 has a certain support for the support beam 1, so it can ensure the stability of the three-gun cleaning machine body 6 during movement.

[0021] The surface of the support beam 1 is provided with a plurality of through grooves 8, and the plurality of through grooves 8 are longitudinally arranged linearly on the surface of the support beam 1. Two protrusions 9 are fixedly installed on the surface of the cross beam 2. The shape of the protrusions 9 is adapted to the shape of the inner wall of the through grooves 8. The two protrusions 9 are respectively stuck in the through grooves 8 of the two support beams 1, and a connecting component is installed between the protrusions 9 and the inside of the through grooves 8.

[0022] The distance between the two beams 2 is constant, and the three-gun cleaning machine body 6 can only move longitudinally within this range. However, for different heat exchangers, the heights are different, so it is necessary to change the moving range of the three-gun cleaning machine body 6. At this time, the position of the beam 2 can be replaced through the connecting assembly to adapt to different heat exchangers.

[0023] The connecting assembly includes a thread groove 10, which is opened on the surface of the protrusion 9. The front of the protrusion 9 is flush with the front of the beam 2. A bolt 11 is installed inside the thread groove 10. The head of the bolt 11 is against the surface of the support beam 1. The width of the head of the bolt 11 is greater than the width of the through groove 8. When the beam 2 needs to be replaced, the bolt 11 is removed from the inside of the thread groove 10, and then the beam 2 is removed and installed in the inside of the new through groove 8, and then the bolt 11 is fixed, which is convenient for installation and fixing.

[0024] The surface of the support beam 1 is provided with a transverse groove 12, the surface of the cross beam 2 is fixedly installed with a limit block 13, the protrusion 9 is fixed on the surface of the limit block 13, and the limit block 13 is stuck in the inside of the transverse groove 12. When the cross beam 2 is reinstalled, the limit block 13 is stuck in the inside of the transverse groove 12 to ensure the accuracy of the installation position.

[0025] The eccentric rod 7 and the support beam 1 are an integrated structure to ensure the stability of the connection.

[0026] It should be noted that the utility model is a multi-directional motion positioning mechanism for a three-gun cleaning machine. When in use, the center of gravity of the bracket composed of the support beam 1 and the cross beam 2 is located in the plane of the bracket. Since the three-gun cleaning machine body 6 is installed on one side of the cross beam 2, the overall center of gravity will be offset and moved to the outside of the bracket. At this time, during the movement, the center of gravity will continue to move, resulting in unstable installation of the support beam 1 and the cross beam 2. However, the eccentric rod 7 has a certain support for the support beam 1, so it can ensure the stability of the three-gun cleaning machine body 6 during movement. If the position of the cross beam 2 needs to be replaced, the bolt 11 is removed from the inside of the threaded groove 10, and then the cross beam 2 is removed and installed to the inside of the new through groove 8, and then the bolt 11 is fixed to adapt to heat exchangers of different heights.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
