Abstract
The utility model discloses a supporting tube for a hoist trolley frame, which is characterized in that the supporting tube for the hoist trolley frame comprises a supporting tube body, wherein an inclined chamfer is disposed on one end of the supporting tube body, longitudinal symmetrical bolt holes are disposed on the other end of the supporting tube body and the external diameter of the supporting tube body is matched with the inner diameter of installation holes for the supporting tube on the hoist trolley frame. The supporting tube for the hoist trolley frame in the utility model has the advantages that the supporting tube for the hoist trolley frame is simple in structure, simple in assembly, small in time consuming and low in production cost.
Description
Technical field
The utility model relates to a kind of support tube, especially a kind of hoist crab frame support tube.
Background technology
In prior art, conventional single-beam hoist-type trolley frame does not have chamfering or only processes very little chamfering with support tube two ends, its support tube adopts H8/H7 level to coordinate with trolley frame, be difficult to pack into, while assembling a pair of single-beam hoist-type trolley frame, at least need 3 assembly manipulation Collaboration operations, expend at least 1 hour and just can complete, take time and effort and productive costs higher.
Summary of the invention
The utility model object is: provide a kind of simple in structure, easy to assembly and hoist crab frame support tube that productive costs is low.
The technical solution of the utility model is: a kind of hoist crab frame support tube, it is characterized in that, comprise support tube body, in described support tube body one end, be provided with ramp down angle, at the described support tube body other end, be provided with laterally zygomorphic bolt hole, described bolt hole aligns with corresponding bolt hole on hoist crab frame, and is tightened by bolts.
Preferably, described this body diameter of support tube matches with the support tube mounting hole internal diameter on described hoist crab frame.
Preferably, the oblique angle at described ramp down angle is more than or equal to 30 °.
The utility model is when installing hoist crab frame, concrete installation steps are as follows, support tube body one end with ramp down angle is penetrated in the support tube mounting hole of hoist crab frame, adjust support tube body upper bolt hole and align with corresponding bolt hole on hoist crab frame, and be tightened by bolts; Then another hoist crab frame is inserted in to the support tube body one end with ramp down angle, adjusting screw(rod) is penetrated to assembly opening corresponding on hoist crab frame, by the nut on adjusting screw(rod), regulate dolly lower edge width, jam nut, assembles thereby complete trolley frame afterwards.
The utility model has the advantages that: adopt the utility model hoist crab frame with support tube not only simple in structure, assemble simple, consuming time less, and productive costs is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model A-A direction cutaway view;
Fig. 3 is the utility model scheme of installation;
Wherein: 1 support tube body, 2 ramp down angles, 3 bolts hole, 4 hoist crab framves, 5 bolts, 6 adjusting screw(rod)s.
The specific embodiment
Embodiment: shown in 3, a kind of hoist crab frame support tube, comprise support tube body 1, in support tube body 1 one end, be provided with ramp down angle 2, at support tube body 1 other end, be provided with laterally zygomorphic bolt hole 3, support tube mounting hole internal diameter on support tube body 1 external diameter and hoist crab frame 4 matches, and the oblique angle at ramp down angle 2 is more than or equal to 30 °.
Shown in Fig. 3, the utility model is when installing hoist crab frame, concrete installation steps are as follows, support tube body 1 one end with ramp down angle 2 is penetrated in the support tube mounting hole of hoist crab frame 4, adjust support tube body 1 upper bolt hole 3 and align with corresponding bolt hole on hoist crab frame 4, and lock with bolt 5; Then another hoist crab frame 4 is inserted in to support tube body 1 one end with ramp down angle 2, adjusting screw(rod) 6 is penetrated to assembly opening corresponding on hoist crab frame 4, by the nut on adjusting screw(rod) 6, regulate dolly lower edge width, jam nut, assembles thereby complete trolley frame afterwards.The utility model has the advantage of adopt the utility model hoist crab frame with support tube not only simple in structure, assemble simple, consuming time less, and productive costs is low.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All modifications of doing according to the Spirit Essence of the utility model main technical schemes, within all should being encompassed in protection domain of the present utility model.
