[0001] This utility model relates to the technical field of heating and drying devices, and in particular to a heating and drying device for steel pipes. Background Technology

[0002] The heating and drying device is a device used to process the surface of steel pipes. When using the heating and drying device, the steel pipe is placed inside the sliding frame, and then the sliding frame is placed inside the limiting box. The connecting door is then closed, and the temperature inside the limiting box is increased by electric heating rods, which facilitates the heating and drying of the steel pipe.

[0003] The inventors found in their daily work that the heating and drying device still has at least the following problems: When using the heating and drying device, the steel pipe is placed inside the sliding frame, and then the sliding frame is placed inside the limiting box. The connecting door is then closed, and the temperature inside the limiting box is increased by the electric heating rod. This makes it easy to heat and dry the steel pipe. However, in actual use, because the temperature of the processed steel pipe is too high, it is troublesome to disassemble the steel pipe. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steel pipe heating and drying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel pipe heating and drying device, comprising a connecting box, a limiting box fixedly connected to the top of the connecting box, heating rods evenly installed on the inner wall of the limiting box, a connecting door hinged to one side of the top of the limiting box, a sliding frame slidably connected to the inner wall of the limiting box, a connecting device provided at the bottom of the connecting box, the connecting device comprising a sliding rod, a sliding groove provided at the bottom of the inner wall of the limiting box, the inner wall of the sliding groove slidably connected to the bottom of the sliding frame, one side of the inner wall of the sliding groove and one end of the sliding rod fixedly connected, and the sliding rod slidably penetrating and inserted into one side of the sliding frame.

[0006] The effect achieved by the above components is as follows: when using the connecting device, the sliding frame is manually controlled to slide on the inner wall of the slide groove, thereby allowing the sliding frame to slide at the bottom of the limiting box. This makes it easy to slide the sliding frame out of the limiting box, which makes it easier to remove the steel pipe from the inside of the limiting box.

[0007] Preferably, a first support frame and a second support frame are fixedly connected to one side of the connecting box, and both the first support frame and the second support frame are located at the bottom of the sliding frame.

[0008] The effect achieved by the above components is that the sliding frame that slides out of the limit box can be well supported by the first support frame and the second support frame.

[0009] Preferably, the top of the second support frame is provided with a connecting groove, and a locking block is slidably connected to the inner wall of the connecting groove.

[0010] The effect achieved by the above components is as follows: because the second support frame is slightly lower than the first support frame, the locking block is slid to the bottom of the sliding frame through the connecting groove, which increases the height of the second support frame. This makes it easier to support the sliding frame through the first and second support frames. The locking block can be manually controlled to move away from the bottom of the sliding frame, so that the sliding frame can tilt in one direction, which makes it easier to tilt the steel pipe down.

[0011] Preferably, the top of the locking block is provided with a groove, and a roller is rotatably inserted into the inner wall of the groove, and the roller is disposed at the bottom of the sliding frame.

[0012] The effect achieved by the above components is that when the locking block slides at the bottom of the sliding frame, the roller is driven to rotate, thereby allowing the locking block to slide well at the bottom of the sliding frame.

[0013] Preferably, a first damping rod is fixedly connected to one side of the inner wall of the groove, one end of the first damping rod is fixedly connected to one side of the inner wall of the groove, one end of the first damping rod near the inside of the groove is fixedly connected to one side of the locking block, a first spring is sleeved on the surface of the first damping rod, one end of the first spring is fixedly connected to one side of the inner wall of the groove, and one end of the first spring near the locking block is fixedly connected to one side of the locking block.

[0014] The effect achieved by the above components is that the locking block is pulled towards the connecting box by the first spring, which makes it easier to restrict the locking block to the bottom of the sliding frame.

[0015] Preferably, a fixing device is provided on one side of the connecting box. The fixing device includes an extension plate, which is fixedly connected to one side of the connecting box. A locking strip is provided on the side of the extension plate away from the connecting box. A limiting groove is provided on one side of the extension plate, and a pressing plate is slidably connected to the inner wall of the limiting groove.

[0016] The effect achieved by the above components is that when using the fixing device, the collection frame is placed on one side of the extension plate and between the locking strip and the squeezing plate, which makes it easy to restrict the collection frame to one side of the extension plate.

[0017] Preferably, a threaded rod is rotatably inserted into one side of the limiting groove, and the threaded rod is threadedly inserted into one side of the extrusion plate.

[0018] The effect achieved by the above components is that the screw rod can be manually controlled to rotate, which can effectively drive the extrusion plate to press against one side of the collection frame.

[0019] Preferably, a second damping rod is fixedly connected to the side of the extension plate away from the locking strip, and a connecting plate is fixedly connected to the end of the second damping rod away from the extension plate. A second spring is sleeved on the surface of the second damping rod, and one end of the second spring is fixedly connected to one side of the extension plate, and the end of the second spring away from the extension plate is fixedly connected to one side of the connecting plate.

[0020] The effect achieved by the above components is that when the collection box approaches the extension plate, the second spring is compressed, which can, to a certain extent, prevent the collection box from hitting one side of the extension plate with great force.

[0021] In this utility model, by setting a connecting device, when using the connecting device, the sliding frame is manually controlled to slide on the inner wall of the slide groove, thereby making the sliding frame slide at the bottom of the limiting box. This makes it easy to slide the sliding frame out of the limiting box, which makes it easier to take the steel pipe out of the limiting box. Attached Figure Description

[0027] Example 1, as Figure 1-4As shown, a steel pipe heating and drying device is provided. A limiting box 2 is fixedly connected to the top of a connecting box 1. Electric heating rods 3 are evenly installed on the inner wall of the limiting box 2. A connecting door 4 is hinged to one side of the top of the limiting box 2. A sliding frame 5 is slidably connected to the inner wall of the limiting box 2. A connecting device 6 is provided at the bottom of the connecting box 1. When using the heating and drying device, the steel pipe is placed inside the sliding frame 5, and then the sliding frame 5 is placed inside the limiting box 2. The connecting door 4 is then closed. The temperature inside the limiting box 2 is increased by the electric heating rods 3, which facilitates the heating and drying of the steel pipe.

[0028] Reference Figure 2 and Figure 3The connecting device 6 includes a sliding rod 602. A groove 601 is provided at the bottom of the inner wall of the limiting box 2. The inner wall of the groove 601 is slidably connected to the bottom of the sliding frame 5. One side of the inner wall of the groove 601 is fixedly connected to one end of the sliding rod 602. The sliding rod 602 is slidably inserted through and inserted into one side of the sliding frame 5. When using the connecting device 6, the sliding frame 5 is manually controlled to slide along the inner wall of the groove 601, thereby allowing the sliding frame 5 to slide at the bottom of the limiting box 2. This facilitates sliding the sliding frame 5 out of the limiting box 2, making it easier to remove the steel pipe from inside the limiting box 2. A first... Support frame 603 and second support frame 610 are both located at the bottom of the sliding frame 5. These support frames effectively support the sliding frame 5 as it slides out of the limiting box 2. The top of the second support frame 610 has a connecting groove 604, and a locking block 605 is slidably connected to the inner wall of the connecting groove 604. Because the second support frame 610 is slightly lower than the first support frame 603, the locking block 605 is slid to the bottom of the sliding frame 5 via the connecting groove 604, thus increasing the height of the second support frame 610 and facilitating passage. The sliding frame 5 is supported by the first support frame 603 and the second support frame 610. The locking block 605 is manually controlled to move away from the bottom of the sliding frame 5, allowing the sliding frame 5 to tilt in one direction, facilitating the tipping of the steel pipe. The top of the locking block 605 has a groove 606, and a roller 607 is rotatably inserted into the inner wall of the groove 606. The roller 607 is located at the bottom of the sliding frame 5. When the locking block 605 slides at the bottom of the sliding frame 5, the roller 607 is driven to rotate, allowing the locking block 605 to slide smoothly at the bottom of the sliding frame 5. One side of the inner wall of the groove 606 is fixedly connected to... A first damping rod 608 is provided. One end of the first damping rod 608 is fixedly connected to one side of the inner wall of the groove 606. The end of the first damping rod 608 near the inside of the groove 606 is fixedly connected to one side of the locking block 605. A first spring 609 is sleeved on the surface of the first damping rod 608. One end of the first spring 609 is fixedly connected to one side of the inner wall of the groove 606. The end of the first spring 609 near the locking block 605 is fixedly connected to one side of the locking block 605. The locking block 605 is pulled towards the connecting box 1 by the first spring 609, which makes it easier to restrict the locking block 605 to the bottom of the sliding frame 5.

[0029] Reference Figure 4A fixing device 7 is provided on one side of the connecting box 1. The fixing device 7 includes an extension plate 701, which is fixedly connected to one side of the connecting box 1. A locking strip 702 is provided on the side of the extension plate 701 away from the connecting box 1. A limiting groove 703 is provided on one side of the extension plate 701. An extrusion plate 704 is slidably connected to the inner wall of the limiting groove 703. When using the fixing device 7, the collection frame is placed on one side of the extension plate 701 and between the locking strip 702 and the extrusion plate 704. This makes it easy to restrict the collection frame to one side of the extension plate 701. A threaded rod 705 is rotatably inserted through one side of the limiting groove 703. The threaded rod 705 is threaded through and inserted into one side of the extrusion plate 704. The threaded rod 705 is manually rotated, which can effectively drive the extrusion plate 704 to press against one side of the collection frame. A second damping rod 706 is fixedly connected to the side of the extension plate 701 away from the locking strip 702. A connecting plate 708 is fixedly connected to the end of the second damping rod 706 away from the extension plate 701. A second spring 707 is sleeved on the surface of the second damping rod 706. One end of the second spring 707 is fixedly connected to one side of the extension plate 701, and the other end of the second spring 707 away from the extension plate 701 is fixedly connected to the side of the connecting plate 708. When the collection frame approaches the extension plate 701, the second spring 707 is compressed, which can prevent the collection frame from hitting the side of the extension plate 701 with great force to a certain extent.

[0030] Working principle: When using the heating and drying device, the steel pipe is placed inside the sliding frame 5, which in turn is placed inside the limiting box 2. Then, the connecting door 4 is closed, and the temperature inside the limiting box 2 is increased by the heating rod 3, which facilitates the heating and drying of the steel pipe. When using the connecting device 6, the sliding frame 5 is manually controlled to slide on the inner wall of the sliding groove 601, which in turn allows the sliding frame 5 to slide at the bottom of the limiting box 2. This makes it easy to slide the sliding frame 5 out of the limiting box 2, thus facilitating the removal of the steel pipe from the limiting box 2. Because the second support frame 610 is slightly lower than the first support frame 603, the locking block 605 is slid to the bottom of the sliding frame 5 through the connecting groove 604. The locking block 605 is pulled towards the connecting box 1 by the first spring 609, which helps to restrict the locking block 605 at the bottom of the sliding frame 5. This increases the height of the second support frame 610, which facilitates the passage of the first spring 609. Support frame 603 and second support frame 610 support the sliding frame 5. Manually control the locking block 605 away from the bottom of the sliding frame 5. When the locking block 605 slides at the bottom of the sliding frame 5, the roller 607 is driven to rotate, so that the locking block 605 can slide well at the bottom of the sliding frame 5. This allows the sliding frame 5 to tilt in one direction, which makes it easier to tilt the steel pipe down. When using the fixing device 7, the collecting frame is set on one side of the extension plate 701, and then the threaded rod 705 is manually controlled to rotate. This can effectively drive the extrusion plate 704 to press against one side of the collecting frame. The collecting frame is set between the locking strip 702 and the extrusion plate 704, which makes it easier to restrict the collecting frame to one side of the extension plate 701. When the collecting frame is close to the extension plate 701, the second spring 707 is compressed, which can prevent the collecting frame from hitting the side of the extension plate 701 with great force to a certain extent.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
