Description

Technical Field

[0001] The utility model relates to the technical field of spline shaft transportation, in particular to a spline shaft hanger. Background Art

[0002] The spline shaft has a neck at one end with the teeth, that is, the diameter of the teeth is larger than the diameter of the adjacent parts, so that a rope can be tied to the neck when the spline shaft is hoisted, and the teeth are used to limit the rope from falling off. Although the spline shaft can be safely hoisted most of the time, when the rope is loose, it is easy for the rope to fall off the neck of the spline shaft, and the spline shaft will fall off the rope, which may easily cause a safety accident. At the same time, the fallen spline shaft will be damaged by impact under the action of gravity. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a spline shaft hoist which can still hoist the spline shaft when the rope is loose.

The top surface of each of the clamping members is used to support the spline shaft. Each of the clamping members is provided with a clamping groove, which is vertically arranged. When the clamping members clamp the spline shaft, the spline shaft is located in the clamping groove. The first ends of the two clamping members are rotatably connected, and the second ends of the two clamping members are connected by a locking mechanism. When the locking mechanism is locked, the clamping members can clamp the spline shaft, and when the locking mechanism is unlocked, the spline shaft can be detached from the clamping groove.

[0005] Furthermore, each of the clamping members is also provided with a clamping protrusion, and the clamping protrusion is located in the clamping groove.

[0006] Furthermore, the hardness of the clamping protrusion is less than the hardness of the spline shaft.

[0007] Furthermore, the clamping member includes a clamping body, a top plate and a bottom plate, wherein the top plate is fixed to the top surface of the clamping body, and the bottom plate is fixed to the bottom surface of the clamping body.

[0008] Furthermore, the first ends of the two clamping members are connected via a hinge mechanism, the clamping members are provided with a mounting notch, and the hinge mechanism is located in the mounting notch.

[0009] Furthermore, the hinge mechanism includes a connecting block and a pivot shaft, both ends of the connecting block are provided with a pivot shaft, and the pivot shaft is installed on the clamping member.

[0010] Furthermore, the locking mechanism includes a locking rod and a locking pin, the locking rod is inserted through the two clamping members, the locking pin is inserted into the locking rod and the clamping member at the same time, and the locking pin is inserted into the locking rod and the clamping member in a vertical direction.

[0011] Furthermore, a limiting groove is provided on the clamping member into which the locking pin is inserted, and the locking pin is located in the limiting groove.

[0012] Furthermore, a protective rubber sleeve is provided on the locking rod.

[0013] Furthermore, the locking mechanism includes a locking screw and a locking nut. The locking screw is passed through the two clamping members and is threadedly connected with the locking nut to lock the two clamping members.

DETAILED DESCRIPTION

[0021] The utility model will be further described below in conjunction with the accompanying drawings.

[0022] like Figure 1As shown, the preferred embodiment of the spline shaft hanger of the utility model includes a locking mechanism 2, two lifting rings 3 and two clamping members 1. The two clamping members 1 are symmetrically arranged. The first ends of the two clamping members 1 are connected by a hinge mechanism 4. Of course, in other embodiments, the two clamping members 1 can be directly pivoted or hinged by a rotating shaft so that the two clamping members 1 can rotate relative to each other. The second ends of the two clamping members 1 are connected by a locking mechanism 2. When the locking mechanism 2 is unlocked, the two clamping members 1 can rotate relative to each other. When the locking mechanism 2 is locked, the two clamping members 1 can clamp the neck of the spline shaft. Each lifting ring 3 is provided on each clamping member 1. The lifting equipment is a rope fixed on the lifting ring 3 to lift the spline shaft hanger.

[0023] like Figures 2 to 4 As shown, the top surface of each clamping member 1 is used to support the tooth portion of the spline shaft, and each clamping member 1 is provided with a clamping groove, which is vertically arranged to facilitate clamping the neck of the spline shaft, that is, when the clamping member 1 clamps the spline shaft, the neck of the spline shaft is located in the clamping groove. Each clamping member 1 is provided with a clamping protrusion 14, and the clamping protrusion 14 is located in the clamping groove, which can reduce the contact area and minimize the area that may be damaged and scratched. The hardness of the clamping protrusion 14 is less than the hardness of the spline shaft, so as to further avoid damage to the spline shaft during the clamping or clamping process.

[0024] Specifically, the clamping member 1 includes a clamping body 11, a top plate 12 and a bottom plate 13. The top plate 12 is welded and fixed to the top surface of the clamping body 11, and the bottom plate 13 is welded and fixed to the bottom surface 13 of the clamping body 11. The clamping member 1 is divided into three structures, which can reduce the weight of the entire clamping member 1 and facilitate the picking up of the entire sling. In other embodiments, the clamping body 11, the top plate 12 and the bottom plate 13 can also be integrally formed for easy processing and manufacturing. The top plate 12, the bottom plate 13 and the clamping body 11 are concave in the direction away from the other clamping member 1 at the side wall close to the other clamping member 1, thereby forming a clamping groove. The side walls of the clamping body 11, the top plate 12 and the bottom plate 13 are flush at the side walls where the clamping groove is formed. The length of the clamping body 11 in the longitudinal direction is smaller than the length of the top plate 12 and the bottom plate 13 in the same direction, so that the clamping member 1 forms a mounting notch at the first end. The space formed by the mounting notch is used as the space required for installing the hinge mechanism 4. The top plate 12 and the bottom plate 13 are both provided with mounting holes, and the mounting holes are used to install the hinge mechanism 4. A locking connecting plate 15 connected to the clamping body 11 is provided at the second end of the clamping member 1, and the locking mechanism 2 is installed on the locking connecting plate 15. A limiting sleeve 23 is also provided on the locking connecting plate 15 on one of the clamping members 1, and the limiting sleeve 23 is used to limit the locking mechanism 2. Screw holes are provided on the top plate 12 and the bottom plate 13, and the lifting ring 3 is screwed in the screw holes. In order to prevent the top plate 12 and the bottom plate 13 from being easily deformed, a support tube 16 adapted to the lifting ring 3 is provided between the top plate 12 and the bottom plate 13, and the support tube 16 is welded to the locking body. It should be known that the support tube 16 can also be integrated with the locking body, and can also have no connection relationship with the locking body.

[0025] The hinge mechanism 4 includes a connecting block 41 and a pivot shaft 42. The two ends of the connecting block 41 are rotatably provided with the pivot shaft 42. The pivot shaft 42 is installed in the installation hole, so as to connect the two clamping members 1 and enable relative rotation.

[0026] The locking mechanism 2 includes a locking rod 21 and a locking pin 22. The locking rod 21 is inserted into the locking connecting plates 15 of the two clamping members 1, that is, one end of the locking rod 21 is inserted into the locking connecting plate 15 on one clamping member 1, and the other end of the locking rod 21 is inserted into the other locking connecting plate 15. At the same time, the other end of the locking rod 21 also passes through a limiting sleeve 23, and the limiting sleeve 23 is used to limit the shaking of the locking rod 21 in the radial direction. A protective rubber sleeve 24 is provided on the locking rod 21, and the protective rubber sleeve 24 is used to protect the spline shaft to prevent the locking rod 21 from hitting the spline shaft and scratching the spline shaft. The locking pin 22 is first inserted into the top plate 12 of the clamping member 1 from the vertical direction, and then inserted into the locking rod 21, and passes through the locking rod 21, thereby locking the locking rod, so that the locking rod cannot fall off from the locking connecting plate 15, thereby locking the two clamping members 1. The limiting sleeve 23 is provided with a limiting groove 231 in the vertical direction. When the locking pin 22 is inserted into the locking rod 21, the locking pin 22 is located in the limiting groove 231 to limit the shaking of the locking pin 22. In other embodiments, the locking mechanism 2 includes a locking screw 32 and a locking nut. The locking screw 32 is passed through the two clamping members 1 and is screwed with the locking nut to lock the two clamping members 1. Tightening the locking screw 32 will lock the clamping member 1, and loosening the locking screw 32 will loosen the clamping member 1. The locking nut can be welded on the locking connecting plate 15, or it can be a part of the locking connecting plate 15.

[0027] The lifting ring 3 includes a connecting ring 31 and a screw rod 32 . The screw rod 32 is integrated with the connecting ring 31 . The screw rod 32 is screwed into a screw hole. When lifting is required, the rope of the lifting device is fixed to the connecting ring 31 .

[0028] During hoisting, first insert the neck of the spline shaft into the locking groove, then insert the locking rod 21 into the locking connecting plate 15, and then insert the locking pin 22 into the locking rod 21 to complete the clamping of the spline shaft. The locking mechanism 2 is used for locking and clamping, so that the clamp 1 is clamped on the neck of the spline shaft, and the top of the clamp 1 is used to support the teeth of the spline shaft. The hoisting rope is connected to the lifting ring 3. Even if the rope is loose, it will not affect the clamping of the spline shaft by the clamp 1. The clamp 1 can still stably clamp the spline shaft and will not be affected by the loose rope, which is highly safe. It should be noted that the loose rope mentioned in this description refers to the enlargement of the fastening circle formed after the rope is knotted, rather than the looseness at the knot position.

[0029] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
