Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and in particular to a clamping fixture for heat exchanger pipes. Background Technology

[0002] Shell-and-tube heat exchangers, also known as tubular heat exchangers, mainly work by injecting liquids of different temperatures into the tubes and shell, allowing their temperatures to interact and cooling the higher-temperature liquid while heating the lower-temperature liquid. This type of heat exchanger has a simple structure and low cost, making it the most widely used type of heat exchanger.

[0003] However, existing shell-and-tube heat exchangers are inconvenient to pipe and have low heat exchange efficiency. Therefore, multiple shell-and-tube heat exchangers are usually used in series or parallel, which makes the pipe connection and layout between shell-and-tube heat exchangers more complicated. When installing large metal pipes, it is not convenient to support and adjust the height of the other end of the pipe. If the pipe joints are not properly connected, it will cause a reduction in service life. Utility Model Content

[0005] The technical solutions adopted in the embodiments of this application are as follows.

[0006] A clamping fixture for heat exchanger pipes includes a base, a support plate mounted on the base, a movable rod sliding on the base, a guide rod guiding the movable rod, a movable component driving the movable rod to move up and down, a clamping component mounted on the end face of the movable rod, a locking component locking the clamping component, and a first block driving the clamping component to gradually move towards the workpiece; a second block is mounted on the base; the movable component is mounted inside the second block; the guide rod is mounted on the support plate and passes through the movable rod; the locking component is mounted at both ends of the clamping component; the first block is mounted on the base and abuts against the side wall of the clamping component.

[0008] As a further improvement to the above technical solution: the guide rod is hexagonal.

[0009] As a further improvement to the above technical solution: the moving part includes a worm gear and a worm meshing with the worm gear; the worm gear rotates within the second block; the worm rotates within the second block; the worm gear is threadedly connected to the moving rod.

[0010] As a further improvement to the above technical solution: the clamping member includes a third block, a clamping plate hinged to the end face of the third block, and a rubber block disposed on the clamping plate; the rubber block array is provided in several ways; the clamping plate is arc-shaped; the third block is disposed on the moving member and the third block moves up and down synchronously with the moving member; the clamping plates are arranged in two sets opposite to each other.

[0011] As a further improvement to the above technical solution: an inclined surface is provided on the side wall of the first block; the inclined surface corresponds to the side wall of the clamping plate; the clamping plate moves down so that the clamping plate gradually moves closer.

[0012] As a further improvement to the above technical solution: the locking component includes a fourth block, a fifth block that rotates within the fourth block, a connector threaded onto the fifth block, and a sixth block corresponding to the connector; both the sixth block and the fourth block are U-shaped; after the connector is inserted into the sixth block, the connector is rotated so that the end faces of the clamps on both sides gradually approach each other.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] 1. Due to the use of a U-shaped base, a support plate is set at the bottom of the base, and a guide rod is set on the support plate. The guide rod is vertically set and can be hexagonal, quadrilateral, or pentagonal. A movable rod is slidably connected to the base. The side wall of the movable rod is threaded. A second block is set at the bottom of the base, which corresponds to the axis of the movable rod. The movable rod passes through the second block, and a worm gear is set inside the second block. The axis of the worm gear corresponds to the movable rod, and the worm gear is threadedly connected to the thread of the movable rod. The worm gear rotates inside the second block, and the worm rotates inside the second block and meshes with the worm gear. A hexagonal groove is set on the end face of the worm to facilitate rotation. When the worm rotates, it drives the worm gear to rotate, causing the worm gear to move up and down on the thread on the movable rod. At the same time, the worm gear is stationary, which causes the movable rod to move up and down. The guide rod limits the angle of the movable rod, so the movable rod moves up and down but does not rotate.

A first piece is provided on the base. Two sets of first pieces are arranged opposite each other and correspond to the clamping plates. An inclined surface is provided on the first piece. The inclined surface contacts the outer wall of the clamping plate and causes the clamping plate to gradually approach, thereby realizing rapid clamping of the pipe sidewall and preventing loosening of the clamping by the moving part.

[0030] The base 1 is U-shaped, with a support plate 2 at its bottom. A guide rod 4 is mounted on the support plate 2, and the guide rod 4 is vertically oriented. The guide rod 4 can be hexagonal, quadrilateral, or pentagonal. A movable rod 3 is slidably connected to the base 1, and the side wall of the movable rod 3 is threaded. A second block 11 is located at the bottom of the base 1, and the second block 11 corresponds to the axis of the movable rod 3. The movable rod 3 passes through the second block 11, and a worm gear 51 is installed inside the second block 11, with the axis of the worm gear 51 corresponding to the movable rod 3. Furthermore, the worm gear 51 is threadedly connected to the thread of the moving rod 3. The worm gear 51 rotates inside the second block 11, and the worm 52 rotates inside the second block 11 and meshes with the worm gear 51. A hexagonal groove is provided on the end face of the worm 52 to facilitate rotation. When the worm 52 rotates, it drives the worm gear 51 to rotate, thereby causing the worm gear 51 to move up and down on the thread on the moving rod 3. At the same time, the worm gear 51 is stationary, thereby causing the moving rod 3 to move up and down.

The base 1 is provided with a first piece 8. There are two sets of first pieces 8 arranged opposite each other and the first piece 8 corresponds to the clamping plate 62. The first piece 8 has an inclined surface 81. The inclined surface 81 contacts the outer wall of the clamping plate 62 and at the same time makes the clamping plate 62 gradually approach each other.

When the sixth block 74 and the connector 73 are engaged, rotating the connector 73 causes the two sets of clamping plates 62 to gradually approach each other until the rubber parts completely clamp the workpiece. The base 1 is provided with a first block 8. Two sets of first blocks 8 are arranged opposite each other and the first block 8 corresponds to the clamping plate 62. The first block 8 has an inclined surface 81. The inclined surface 81 contacts the outer wall of the clamping plate 62 and causes the clamping plate 62 to gradually approach each other, thereby realizing the rapid clamping of the pipe side wall and preventing the clamping from loosening through the moving part 5.
