Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial furnace technology, and in particular to an industrial furnace door clamping device. Background Technology
[0002] An industrial furnace is a thermal device used in industrial production to heat materials or workpieces using heat generated from fuel combustion or electrical energy conversion. Broadly speaking, a boiler is also a type of industrial furnace, but it is conventionally not included within the scope of industrial furnaces.
[0003] In the existing technology, when pressing the furnace door of an industrial furnace, most methods combine the sealing of the furnace door itself with external force to assist in pressing. However, the existing external force-assisted pressing methods are mostly fixed structures, which can easily affect normal material transportation and affect the production efficiency of the industrial furnace. Utility Model Content
[0004] The present invention aims to provide an industrial furnace door clamping device to overcome or at least partially solve the above-mentioned problems.
[0005] To achieve the above objectives, the technical solution of this utility model is specifically implemented as follows:
[0006] This utility model provides an industrial furnace door clamping device, including a furnace door. A top rod is provided on the right side of the furnace door. The top rod is inserted into a guide seat and moves left and right along the guide seat. The right side of the top rod is connected to a locking cylinder. The locking cylinder and the guide seat are both fixedly connected to the inner side of a connecting plate. A U-shaped channel steel is provided on the outer side of the connecting plate, and a fixing plate is welded and fixed on the outer side of the U-shaped channel steel. A telescopic cylinder is fixedly connected to the outer side of the fixing plate, and the telescopic rod of the telescopic cylinder is fixedly connected to the connecting plate. A connecting seat is also fixed on the outer side of the U-shaped channel steel. The connecting seat is sleeved on a lead screw. The left end of the lead screw is connected to the output shaft of a servo motor. The servo motor and the lead screw are both located on the front and rear sides of the furnace door.
[0007] As a further embodiment of this utility model, the U-shaped channel steel has an internal placement cavity.
[0008] As a further embodiment of this utility model, a guide groove is provided on the lower side of the U-shaped channel steel, and a guide rail is provided in the guide groove. The guide rail is respectively provided on the front and rear sides of the furnace door, and the U-shaped channel steel moves left and right along the guide rail through the guide groove.
[0009] This utility model provides an industrial furnace door clamping device, which has the following advantages: it achieves the purpose of auxiliary clamping of the industrial furnace door, and at the same time facilitates the storage and extension of the top rod, without affecting the normal operation of the industrial furnace, ensuring the operating efficiency of the industrial furnace. It is simple to operate and has good performance. Attached Figure Description

[0013] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0014] See Figure 1 This utility model provides an industrial furnace door 1 clamping device, including a furnace door 1. A top rod 2 is provided on the right side of the furnace door 1. The top rod 2 is inserted into a guide seat 3 and moves left and right along the guide seat 3. The right side of the top rod 2 is connected to a locking cylinder 4. The locking cylinder 4 and the guide seat 3 are both fixedly connected to the inner side of a connecting plate 6. A U-shaped channel steel 5 is provided on the outer side of the connecting plate 6, and a fixing plate 8 is welded and fixed on the outer side of the U-shaped channel steel 5. A telescopic cylinder 7 is fixedly connected to the outer side of the fixing plate 8, and the telescopic rod of the telescopic cylinder 7 is fixedly connected to the connecting plate 6. A connecting seat 9 is also fixed on the outer side of the U-shaped channel steel 5. The connecting seat 9 is sleeved on a lead screw 10. The left end of the lead screw 10 is connected to the output shaft of a servo motor 11. The servo motor 11 and the lead screw 10 are both provided on the front and rear sides of the furnace door 1.
[0015] The U-shaped channel steel 5 has an internal placement cavity 13, which facilitates the retraction of the connecting plate 6 and the top rod 2 into the U-shaped channel steel 5.
[0016] The U-shaped channel steel 5 is provided with a guide groove on its lower side, and a guide rail 12 is provided in the guide groove. The guide rail 12 is respectively provided on the front and rear sides of the furnace door 1. The U-shaped channel steel 5 moves left and right along the guide rail 12 through the guide groove, which facilitates the movement of the U-shaped channel steel 5 and ensures the stability of the movement of the U-shaped channel steel 5.
[0017] In use, the locking cylinder 4 drives the push rod 2 to move to the left along the guide seat 3, and the left end of the push rod 2 contacts the furnace door 1, thereby assisting in tightening the furnace door 1. When it is necessary to open the furnace door 1, the locking cylinder 4 is run again to drive the push rod 2 to reset. Then, the telescopic cylinder 7 is run to drive the connecting plate 6 to move into the placement cavity 13, thereby retracting the connecting plate 6, the push rod 2, and the locking cylinder 4 into the placement cavity 13. Then, the servo motor 11 is run, which can drive the lead screw 10 to rotate. Under the influence of the ball nut, the U-shaped channel steel 5 is driven to move to the left along the guide rail 12, thereby moving the push rod 2 and the locking cylinder 4 to the front and rear sides of the furnace door 1.
