Description

Technical Field

[0001] The utility model relates to the technical field of pressure ring tightening hoop, in particular to a pressure ring tightening hoop device. Background Art

[0002] At present, pressure rings are often replaced during the maintenance of ferrosilicon furnaces. The pressure ring is composed of six pieces, each of which is connected by a stainless steel pin. During on-site maintenance, when the pressure ring is inserted with the last pin, it is usually necessary to use a 5-ton lifting chain to wrap the pressure ring around and then tighten the pressure ring. In order to ensure that the pressure ring is reinstalled in time, a pressure ring tightening device is required.

[0003] For example, a pressure ring tightening device with publication number CN212020531U includes two threaded rods installed in the threaded holes of the pressure ring. The two threaded rods can be installed in the corresponding two threaded holes on the pressure ring respectively, and then the distance between the two threaded rods can be shortened by screwing the nut on the lead screw, thereby tightening the two corresponding parts of the pressure ring, and inserting the last pin at the corresponding position of the pressure ring;

[0004] The pressure ring tightening device shortens the distance between the two threaded rods by screwing the nut on the screw, thereby tightening the two components corresponding to the pressure ring. However, since the ear seat and the screw are arranged on the front end surface of the threaded rod, when the screw is screwed, the force points of the threaded rod are concentrated on the front end. Under the blocking effect of the pressure ring, only the front ends of the two threaded rods will move closer to the middle and deform. Therefore, the tightening effect of the pressure ring is not good. At the same time, the nut on the screw is manually screwed in the above method, but since the tightening force of the pressure ring is very large, the manual operation is relatively labor-intensive. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a pressure ring tightening device, which solves the problem that the existing pressure ring tightening device has a problem that, since the ear seat and the lead screw are arranged on the front end surface of the threaded rod, when the lead screw is screwed, the force points of the threaded rod are concentrated on the front end. Under the blocking effect of the pressure ring, the two threaded rods will only move toward the middle at the front ends and deform. At the same time, the nut on the lead screw is tightened manually in the above-mentioned method. However, since the force of the pressure ring tightening device is very large, the labor degree of manual operation is relatively high.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a pressure ring tightening device, including a pressure ring body, a tightening rod and a one-way thread, a pair of tightening rods are installed inside the upper part of the pressure ring body, the lower outer wall of the tightening rod is processed with a one-way thread, and the tightening rod is connected to the internal thread of the pressure ring body through the one-way thread, a back plate is installed on the rear end face of the tightening rod, a tightening mechanism is installed on the front end face of the back plate, and a connecting mechanism is installed on the left end of the back plate.

[0007] Preferably, the tightening mechanism includes a pair of first vertical plates fixedly connected to the front end face of the back plate, the left and right first vertical plates are internally rotatably connected with a first cross bar, and the outer wall of the first cross bar is processed with a two-way thread, the outer wall of the first cross bar is threadedly connected to a pair of clamps through the two-way threads, and the rear end face of the clamps is in contact with the front end face of the back plate, and the inner side of the clamps is bonded with a rubber pad in contact with the outer wall of the tightening rod.

[0008] Preferably, two pairs of second cross bars are fixedly connected to the inner sides of the left and right first vertical plates, and the outer walls of the second cross bars are gap-matched with the inner walls of the through holes of the clamping plate.

[0009] Preferably, the connection mechanism comprises a pair of second vertical plates fixedly connected to the left side of the rear end surface of the back plate, third vertical plates are fixedly connected to the inner sides of the left and right second vertical plates, and the motor is fixedly connected to the inside of the third vertical plate.

[0010] Preferably, the output shaft of the motor is fixedly connected to a rotating rod, and the front end surface of the rotating rod is fixedly connected to a first bevel gear.

[0011] Preferably, the right side of the front end surface of the first bevel gear is meshedly connected with a second bevel gear fixed to the first cross bar.

[0012] Beneficial Effects

[0013] The utility model provides a pressure ring tightening device, which has the following beneficial effects:

[0014] The clamping rod can be installed on the pressure ring body through a one-way thread, and then the device can be driven to move through the back plate, so that the clamping plate is close to the two clamping rods, and then the motor is started to make the output shaft of the motor drive the rotating rod to rotate, so that the rotating rod can drive the first umbrella gear to rotate, and the first umbrella gear drives the first cross bar to rotate through the second umbrella gear, so that the first cross bar cooperates with the two-way thread and the second cross bar to drive a pair of clamping plates to move inward, so that the clamping plates cooperate with the rubber pads to squeeze the pair of clamping rods, so that the contact area between the clamping rod and the clamping plate is large, and the extrusion force can act on the outer wall of the clamping rod, so that the clamping rod can better clamp the pressure ring body, and the motor is used to drive the first cross bar and the clamping plate to move, which also reduces the degree of labor.
