Abstract
The utility model belongs to the field of building machinery and particularly relates to a hanger rod used by a construction elevator. The hanger rod comprises a hanger rod body, an installation rod and a suspension arm, wherein the suspension arm is arranged at the upper end of the hanger rod body; the lower end of the hanger rod body is sleeved on the installation rod; the hanger rod body can rotate relative to the installation rod; a bearing is sleeved between the hanger rod body and the installation rod; the suspension arm comprises a main beam, a cross beam and a supporting beam which are detachably connected. According to the hanger rod used by the construction elevator disclosed by the utility model, the bearing is sleeved between the hanger rod body and the installation rod, so that friction force between the hanger rod body and the installation rod is greatly reduced, and therefore, the hanger rod body can be enabled to rotate around the installation rod only by acting less force on the hanger rod body, and the labor intensity of working staff is relieved. Besides, the suspension arm is an assembly structure, and therefore, the hanger rod can be convenient for transportation and installation.
Description
Technical field
The utility model belongs to vehicle for construction field, and the suspension rod that particularly a kind of building hoist is used belongs to the improvement technology of the suspension rod that building hoist uses.
Background technology
In today of the high speed development of national economy, the vehicle for constructions such as building hoist start bringing into play huge effect at increasing building field, especially for large-engineering, and skyscraper place, it is particularly important that the use of building hoist seems, it can greatly be boosted productivity and economize labor time.Therefore, people are also more and more higher to the composite request of the various aspects such as the performance of elevator, efficiency, load carrying ability, energy-conservation, maintenance.
Building hoist is in the process of Assembly &Disassembly at present, sometimes to utilize the tower crane in building site to assist operation, but do not having tower crane or tower crane that the building site of use can not be provided, the standard knot of elevator and the installing/dismounting of wall-attached frame all need a suspension rod of elevator outfit to install.Existing most suspension rod exists and rotates painstakingly, when suspension rod lifting 1 joint standard knot, needs 2 staff could rotate suspension rod, has greatly affected work efficiency.The arm of now a lot of suspension rods is all one welding simultaneously, during transportation, relatively takes up room.
Summary of the invention
The purpose of this utility model is for above-mentioned problem, to propose a kind of rotation to be easy to the suspension rod that building hoist is used.
In order to achieve the above object, the technical scheme that the utility model is taked: the suspension rod that a kind of building hoist is used, comprise boom body, mounting rod and arm, arm is arranged on boom body upper end, the lower end of boom body is sleeved on mounting rod, suspension rod physical efficiency is rotated relative to mounting rod, between described boom body and mounting rod, is set with bearing.
In such scheme, due to the effect of bearing, greatly reduce the friction force between boom body and mounting rod, made boom body can be easy to rotate relative to mounting rod.
The sidewall of above-mentioned mounting rod is provided with projection, and the upper surface of bearing contacts with boom body, and the lower surface of bearing contacts with projection.
Above-mentioned boom body is provided with motor installation position.
Because bearing need to bear larger axial force, above-mentioned rolling bearing is tapered roller bearing.
For convenient transportation and installation, above-mentioned arm comprises girder, crossbeam and support beam, and the lower end of girder and boom body upper end removably connect, and crossbeam and girder removably connect, and the two ends of support beam removably connect with girder and crossbeam respectively.
The cavity that above-mentioned girder, crossbeam and support beam surround is triangular in shape, has improved the intensity of arm.
The utility model is owing to being set with tapered roller bearing between boom body and mounting rod, greatly reduced the friction force between boom body and mounting rod, therefore only need less masterpiece to be used on boom body and just can make boom body rotate around mounting rod, alleviated staff's labour intensity; In addition, because arm is splicing structure, therefore can conveniently transport and install.
Accompanying drawing explanation
Fig. 1 is the exploded drawings of suspension rod of the present utility model.
Fig. 2 is the appearance assumption diagram of suspension rod of the present utility model.
Fig. 3 is the front view of suspension rod of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Wherein accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; For better explanation the following example, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known features and explanation thereof may to omit be understandable.
Embodiment
The structure of the suspension rod that building hoist of the present utility model is used as shown in Figures 1 to 3, comprise boom body 1, mounting rod 2, arm 3 and bearing 4, arm 3 is arranged on the upper end of boom body 1, the lower end of boom body 1 is sleeved on mounting rod 2, the sidewall of mounting rod 2 is provided with projection 21, bearing 4 is sleeved on mounting rod 2, and the lower surface of bearing 4 21 contacts with projection, and the upper surface of bearing 4 contacts with boom body 1.During use, because bearing 4 need to bear larger axial force, so the bearing in the present embodiment 4 is preferentially selected tapered roller bearing.
Above-mentioned boom body 1 is provided with motor installation position 11, and motor 5 is arranged on the motor installation position 11 on boom body 1, and motor 5 draws material that power is provided for hanging, and the motor 5 of the present embodiment is winch.
Above-mentioned arm 3 comprises girder 31, crossbeam 32 and support beam 33, girder 31 lower end and boom body 1 upper end are with bolts, crossbeam 32 is with bolts with girder 31, support beam 33 two ends are connected with crossbeam 32 with girder 31 respectively by bolt, and the cavity that girder 31, crossbeam 32 and support beam 33 surround is triangular in shape, further improved the intensity of arm 3, because above-mentioned arm 3 adopts splicing structure, not only convenient transportation, also can easy disassembly.
When the utility model is used, mounting rod 2 is fixed on elevator, if need to change operating direction, firmly rotate boom body 1, boom body 1 can rotate together with arm 3, and mounting rod 2 is not followed rotation, due to the effect of bearing 4, friction force between boom body 1 and mounting rod 2 is diminished greatly, therefore rotate more laborsaving.
The corresponding same or analogous parts of same or analogous label in above-described embodiment; In accompanying drawing, describe position relationship for only for exemplary illustration, can not be interpreted as the restriction to this patent.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.All any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in the protection domain of the utility model claim.
