Description

Technical Field

[0001] The utility model relates to the technical field of flange locking, in particular to a remote automatic control flange locking device. Background Art

[0002] In the fields of chemical industry, nuclear power, etc., some large containers and gates have a diameter of several meters or even more than ten meters. They are connected by flanges and bolts. There are more than a hundred bolts. The diameter and preload force are relatively large, and a torque wrench is used to apply the preload force. Because the equipment has a large diameter, a large number of bolts, and a wide distribution range, a special operating platform is required when working with a manual hand-held torque wrench; to ensure that the preload force is evenly distributed, it is necessary to tighten in symmetrical positions, and multiple rounds of tightening are required. The operation is cumbersome, the work is difficult, the working time is long, and the efficiency is very low; after the equipment has been working for a long time, there is a lack of effective means to check whether the internal pressure, vibration and other factors have caused the bolts to loosen. If they fail, accidents are likely to occur; these equipment are in a harmful environment, and long-term work affects the health of the staff. Therefore, disassembly, assembly and maintenance all generate a lot of workload.

[0003] Bolted connection of large flanges is a common structure with low cost and high reliability in the industry. It is easily accepted and has formed a common method of manual disassembly and assembly. However, in special environments, this traditional connection method of large flanges brings many problems to work and also creates safety hazards. For this reason, we propose a remote automatic control flange locking device. Utility Model Content

[0004] In view of the above problems, the utility model provides a remote automatic control flange locking device, which can lock the flange bolt connection to replace the original bolt connection method.

[0005] The technical solution of the utility model is:

[0006] A remote automatic control flange locking device comprises a first flange and a second flange, wherein the first flange is arranged on one side of the second flange, a bracket is fixedly installed on the second flange, a control box is installed on one side of the bracket, a motor is fixedly installed on one side of the control box, a driven gear is fixedly connected to the output shaft of the motor, the bottom end of the driven gear is meshedly connected to the driving gear, the middle end of the driving gear is fixedly connected to a bidirectional screw rod, clamping plates are arranged at both ends of the outer surface of the bidirectional screw rod, and a bending moment compensator is installed at the middle position of the top ends of the two clamping plates.

[0007] In a further technical solution, a threaded rod is arranged inside the control box and at the rear end of the driving gear, a motor is installed on the top of the threaded rod, a movable cylinder is threadedly connected to the outer surface of the threaded rod, and a slider is fixedly connected to one side of the movable cylinder.

[0008] In a further technical solution, a hinge is installed on one side of the control box close to the bracket, and the other end of the hinge is fixedly installed on the bracket.

[0009] The beneficial effects of the utility model are:

[0010] The motor drives the driven gear and the driving gear to rotate, and the driving gear drives the bidirectional screw to rotate so that the two clamping plates are close to each other. The bottom ends of the two clamping plates lock the connection between the first flange and the second flange, replacing the original method of fastening with bolts, reducing the burden on workers and avoiding workers from working in special environments. It has good development prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings. Example

[0017] like Figure 1-Figure 3 As shown, the remote automatic control flange locking device includes a first flange 1 and a second flange 2, the first flange 1 is arranged on one side of the second flange 2, a bracket 3 is fixedly installed on the second flange 2, a control box 11 is installed on one side of the bracket 3, a motor 4 is fixedly installed on one side of the control box 11, a driven gear 10 is fixedly connected to the output shaft of the motor 4, the bottom end of the driven gear 10 is meshedly connected to the driving gear 5, the middle end of the driving gear 5 is fixedly connected to the bidirectional lead screw 9, the outer surfaces of the bidirectional lead screw 9 are provided with clamping plates 8 at both ends, and a bending moment compensator 7 is installed at the middle position of the top ends of the two clamping plates 8.

[0018] The working principle of the above technical solution is as follows:

[0019] By controlling Xiyong to issue a locking command and control the start of the motor 4, the output shaft of the motor 4 drives the driven gear 10 to rotate, and the driven gear 10 drives the driving gear 5 to rotate, and the driving gear 5 can drive the bidirectional screw 9 to rotate. Since the thread directions at both ends of the bidirectional screw 9 are opposite, and the two clamping plates 8 and the two ends of the bidirectional screw 9 are threadedly connected, the two clamping plates 8 are moved close to each other, so that the connection between the first flange 1 and the second flange 2 can be locked. At the same time, the bending moment compensator 7 is designed to prevent the clamping torque from being too large and causing the bidirectional screw 9 to deform. When the two clamping plates 8 need to be loosened, the output shaft of the motor 4 can be rotated in the opposite direction.

[0020] In another embodiment, if Figure 2 As shown, a threaded rod 12 is provided inside the control box 11 and at the rear end of the driving gear 5, a motor 6 is installed on the top of the threaded rod 12, a movable cylinder 13 is threadedly connected to the outer surface of the threaded rod 12, and a slider 14 is fixedly connected to one side of the movable cylinder 13. After loosening the two clamping plates 8, the threaded rod 12 can be driven to rotate by the starting cabinet motor 6, and the threaded rod 12 drives the movable cylinder 13 to move upward under the action of the slider 14, so that the control box 11 and the two clamping plates 8 and other structures move upward, and can leave the connection between the first flange 1 and the second flange 2.

[0021] In another embodiment, if Figure 3 As shown, a hinge 15 is installed on one side of the control box 11 close to the bracket 3, and the other end of the hinge 15 is fixedly installed on the bracket 3. After loosening the two clamping plates 8, the control box 11 is moved upward to flip it, so that the two clamping plates 8 can be driven to leave the connection between the first flange 1 and the second flange 2.

[0022] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
