Description

Technical Field

[0001] The utility model relates to the technical field of steel belt tensioning, in particular to a steel belt tensioner for leak plugging with pressure. Background Art

[0002] The steel belt tensioner is an indispensable device in the leak plugging system. It plays the role of tightening the steel belt, thereby completing the emergency leak plugging. The tensioners currently used on site have poor tightening effect, unreasonable layout, easy loosening of the steel belt, and bulky overall structure.

[0003] The tensioners currently used have the following problems:

[0004] 1. The steel belt is very easy to loosen. If it cannot be tightened once, it needs to be tightened twice. However, the existing tensioner does not have the function of secondary tightening, which will cause the steel belt to loosen directly (such as a steel belt tensioner disclosed in 2018213359834);

[0005] 2. When tightening, the tightening shaft will move backwards, taking up a large space. If used in a small space, there will be problems with being unable to use or tighten the steel belt, resulting in failure to plug the leak. Utility Model Content

[0006] The utility model aims to solve the technical problems existing in the steel belt tensioner of the prior art and provides a belt pressure leak plugging steel belt tensioner.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A steel belt tensioner for plugging leaks with pressure comprises a first supporting module and a second supporting module. A lead screw shaft is rotatably installed between the first supporting module and the second supporting module. A pulling and pressing movable module is threadedly installed on the lead screw shaft. Positioning rods are passed through both sides of the pulling and pressing movable module. A first steel belt limiting groove is provided on the first supporting module, a second steel belt limiting groove is provided on the pulling and pressing movable module, and locking pieces are provided at the first steel belt limiting groove and the second steel belt limiting groove.

[0009] Furthermore, an operating handle is connected to one side of the first supporting module and the second supporting module.

[0010] Furthermore, the locking member includes a locking screw segment and a polished rod at the end of the locking screw segment, and the diameter of the polished rod is smaller than the diameter of the locking screw segment.

[0011] Furthermore, the first support module and the pulling and pressing movable module are both equipped with locking parts on one side, and the first support module is provided with a first anti-drop plate on one end face, and the pulling and pressing movable module is provided with a second anti-drop plate on one end face, and the first anti-drop plate and the second anti-drop plate are both provided with mounting holes for installing the light rod.

[0012] Furthermore, a knob is provided at the end of the lead screw shaft extending out of the second supporting module.

[0013] Furthermore, first blind holes are provided on both sides of the first supporting module, second blind holes are provided on both sides of the second supporting module, and the positioning rod is connected to the first supporting module and the second supporting module via threads.

[0014] Furthermore, compression nuts are installed at the mounting locations of the positioning rod and the first supporting module and the second supporting module.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model occupies a small space and can be used in a narrow space. After the first tightening, when the second tightening is needed, the locking member on the first supporting module is used to lock the steel belt, and then the pulling and pressing moving module can be loosened for the second tightening. The utility model has a simple structure, strong practicality and is easy to operate.

[0017] The utility model is provided with an operating handle to facilitate grasping and carrying the steel belt tensioner.

[0018] The utility model sets the locking piece into a two-stage structure, and then uses an anti-drop plate. The hole diameter of the anti-drop plate is smaller than the diameter of the locking screw section, which can play a limiting role and prevent the locking piece from falling off. The utility model uses a limiting rod to ensure that the pulling and pressing dynamic module will not rotate when moving, thereby ensuring the movement stability of the pulling and pressing dynamic module.

[0026] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1-6 As shown, a pressure-sealing steel belt tensioner comprises a first support module 1 and a second support module 5 , and an operating handle 8 is welded to one side of the first support module 1 and the second support module 5 .

[0028] A lead screw shaft 4 is rotatably installed between the first support module 1 and the second support module 5 (a first axial hole 13 is provided on the first support module 1, a second axial hole 15 is provided on the second support module 5, and a threaded hole 19 is provided on the pulling and pressing movable module 3), a knob 6 is installed on the end of the lead screw shaft 4 extending out of the second support module 5, and the pulling and pressing movable module 3 is threadedly installed on the lead screw shaft 4, and positioning rods 2 are penetrated on both sides of the pulling and pressing movable module 3, first blind holes 12 are provided on both sides of the first support module 1, and second blind holes 14 are provided on both sides of the second support module 5, the positioning rod 2 is connected to the first support module 1 and the second support module 5 through threads, and a clamping nut 7 is installed at the installation position of the positioning rod 2 and the first support module 1 and the second support module 5 (the connection method between the positioning rod 2 and the first support module 1 and the second support module 5 can also be selected to be fixed).

[0029] The first support module 1 is provided with a first steel belt limiting groove 11, the pulling and pressing movable module 3 is provided with a second steel belt limiting groove 18, and a locking member 10 is installed on one side of the first support module 1 and the pulling and pressing movable module 3, and a locking member 10 is provided near the first steel belt limiting groove 11 and the second steel belt limiting groove 18. The locking member 10 includes a locking screw section 20 and a light rod 21 at the end of the locking screw section 20, and the diameter of the light rod 21 is smaller than the diameter of the locking screw section 20. A first anti-slip plate 9 is fixed to one end surface of the first support module 1, and a second anti-slip plate 16 is fixed to one end surface of the pulling and pressing movable module 3, and a mounting hole for mounting the light rod 21 is provided on the first anti-slip plate 9 and the second anti-slip plate 16.

[0030] When the steel belt needs to be tightened, the steel belt to be tightened is clamped in the first steel belt limiting groove 11 and the second steel belt limiting groove 18, the locking piece 10 on the pulling and pressing movable module 3 is locked, the steel belt is positioned, and then the knob 6 is rotated. Under the rotation of the screw shaft 4, the pulling and pressing movable module 3 moves to the side close to the second support module 5 to tighten the steel belt.

[0031] If the steel belt is not tightened when the pulling and pressing dynamic module 3 is fitted with the second support module 5, it needs to be tightened again. At this time, first lock the locking member 10 on the first support module 1, loosen the locking member 10 on the pulling and pressing dynamic module 3, and return the pulling and pressing dynamic module 3 close to the first support module 1. Then lock the locking member 10 on the pulling and pressing dynamic module 3, loosen the locking member 10 on the first support module 1, and rotate the lead screw shaft 4 for secondary tightening. After the steel belt is tightened, lock the steel belt with its own locking device, then loosen the locking member 10 on the pulling and pressing dynamic module 3, and remove the equipment.
