Description

Technical Field

[0001] This utility model relates to the technical field of bell-type furnace equipment, and in particular to a bell-type furnace heating hood hoisting anti-detachment hook device. Background Technology

[0002] A bell-type furnace is an intermittent industrial heat treatment equipment, mainly composed of a movable heating hood and a fixed furnace platform. It is suitable for processes such as annealing, tempering, sintering, and brazing, and is widely used in metal processing, electronic components, ceramic materials, and other fields. The top surface of the heating hood of the bell-type furnace is equipped with a lifting shaft. During hoisting, the lifting shaft is hooked by a crane hook to lift the heating hood for movement. However, because the overall height of the heating hood is relatively high (5-6 meters), it obscures the top surface of the heating hood. Therefore, it is difficult for workers standing on the ground to observe the situation of the crane hook and the lifting shaft hook. Furthermore, the hook may not be properly engaged, causing the heating hood to fall and break. Therefore, it is necessary to design a new type of heating hood anti-disengagement structure to solve the above problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a baffle and lifting lug of a bell-type furnace heating hood hoisting anti-detachment device. The baffle is connected to the counterweight block through a connecting rope. When the lifting shaft body is hooked with the crane hook, the crane hook abuts against the baffle and drives the baffle to swing upward. The baffle drives the counterweight block to move upward through the connecting rope. After the lifting shaft body and the crane hook complete the hooking action, the counterweight block moves upward and abuts against the limiting sleeve, so that the staff can observe the hooking situation between the crane hook and the lifting shaft body, so as to prevent the heating hood body from falling off and being damaged due to the hook not being in place.

[0004] A hoisting anti-detachment device for a bell-type furnace heating hood includes a counterweight and a baffle plate disposed on the top surface of the heating hood. The top surface of the heating hood is provided with a lifting lug, and a lifting shaft is disposed on the lifting lug. The baffle plate is hinged to the lifting lug, and a connecting rope is disposed on the baffle plate. A limiting sleeve is disposed on the side wall of the top of the heating hood. The connecting rope passes through the limiting sleeve. The counterweight is connected to the connecting rope and can move with the connecting rope to abut against the limiting sleeve.

[0005] Preferably, the lifting lug is provided with a mounting groove, and the lifting shaft is mounted on the lifting lug through the mounting groove.

[0006] Preferably, the baffle is disposed adjacent to the lifting shaft body, and the baffle is hinged to the lifting lug via a rotating shaft.

[0007] Preferably, the baffle is provided with a through hole, and the through hole is connected to the connecting rope.

[0008] Preferably, a roller is provided at the top of the limiting sleeve, and the connecting rope passes through the limiting sleeve after wrapping around the roller.

[0009] Preferably, the counterweight is an inverted conical structure, the top surface of the counterweight is connected to the connecting rope, and the diameter of the counterweight is the same as the outer diameter of the limiting sleeve.

[0010] The beneficial effects of this utility model are as follows: The anti-detachment device for the heating cover of the bell-type furnace is achieved by the cooperation of a counterweight and a baffle, which makes the baffle hinged to the lifting lug. The baffle is connected to the counterweight through a connecting rope. When the lifting shaft is hooked to the crane hook, the crane hook abuts against the baffle and drives the baffle to swing upward. The baffle drives the counterweight to move upward through the connecting rope. After the lifting shaft and the crane hook have completed the hooking action, the counterweight moves upward and abuts against the limiting sleeve, so that the staff can observe the hooking situation between the crane hook and the lifting shaft, so as to prevent the heating cover from falling off and being damaged due to the hook not being in place.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0017] like Figures 1 to 4 As shown, a hoisting anti-detachment device for a bell-type furnace heating hood includes a counterweight 1 and a baffle 2 disposed on the top surface of the heating hood. The top surface of the heating hood is provided with a lifting lug 3, and a lifting shaft 4 is provided on the lifting lug 3. The baffle 2 is hinged to the lifting lug 3, and a connecting rope 5 is provided on the baffle 2. A limiting sleeve 6 is provided on the side wall of the top of the heating hood. The connecting rope 5 passes through the limiting sleeve 6. The counterweight 1 is connected to the connecting rope 5 and can move with the connecting rope 5 to abut against the limiting sleeve 6.

[0018] The working principle of the anti-detachment hook device for the heating hood of the bell-type furnace described in this utility model is achieved through the cooperation of the counterweight 1 and the baffle 2. Figures 1 to 4As shown, the connecting rope 5 can be made of thin steel wire rope. The counterweight 1 is connected to the connecting rope 5, and the weight of the counterweight 1 keeps the connecting rope 5 taut. When the lifting shaft 4 is hooked to the crane hook, the crane hook abuts against the baffle 2 and drives the baffle 2 to swing upward. In this way, the baffle 2 drives the counterweight 1 to move upward through the connecting rope 5. After the lifting shaft 4 and the crane hook have completed the hooking action, the counterweight 1 moves upward and abuts against the limiting sleeve 6. At this time, the staff can observe the state of the counterweight to know that the lifting shaft 4 and the crane hook are hooked in place. Compared with the traditional heating hood, the baffle 2 and the counterweight 1 of the anti-disengagement device for the heating hood of this bell-type furnace work together to facilitate the staff to observe the hooking situation of the crane hook and the lifting shaft 4, so as to prevent the heating hood from falling and being damaged due to the hook not being hooked in place.

[0019] Specifically, the lifting lug 3 is provided with a mounting groove 7, and the lifting shaft 4 is mounted on the lifting lug 3 through the mounting groove 7. The baffle 2 is adjacent to the lifting shaft 4 and is hinged to the lifting lug 3 via a rotating shaft. Further, the baffle 2 is provided with a through hole 8, and the through hole 8 is connected to the connecting rope 5. Even further, the top of the limiting sleeve 6 is provided with a roller 9, and the connecting rope 5 passes through the limiting sleeve 6 after wrapping around the roller 9. The counterweight 1 is an inverted conical structure, the top surface of the counterweight 1 is connected to the connecting rope 5, and the diameter of the counterweight 1 is the same as the outer diameter of the limiting sleeve 6. Figures 1 to 4 As shown, the lifting lug 3 has a concave structure. After the lifting shaft 4 is inserted into the mounting groove 7 of the lifting lug 3, it can be fixed to the lifting lug 3 by bolts. The crane hook abuts against the baffle 2 and drives the baffle 2 to swing upward. The through hole 8 of the baffle 2 is connected to the connecting rope 5. The baffle 2 swings and pulls one end of the connecting rope 5 upward. The connecting rope 5 moves along the roller 9 towards the baffle 2 and drives the counterweight 1 to move upward. After the lifting shaft 4 and the crane hook complete the hooking action, the counterweight 1 moves upward and abuts against the limiting sleeve 6 to prevent the counterweight 1 from falling off the limiting sleeve 6. At this time, the staff observes the state of the counterweight to know that the lifting shaft 4 and the crane hook are hooked in place, avoiding the situation where the hook is not hooked in place, which would cause the heating cover to fall off and be damaged.

[0020] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
