Abstract
The utility model relates to a simple installation structure of a non-power drum shaft. The simple installation structure comprises a drum, a drum shaft, a bearing mounted between the drum and the drum shaft, and brackets used for supporting the two ends of the drum shaft, wherein the drum shaft penetrates through the center of the drum, the two ends of the drum shaft are round structures, and pin shaft holes are respectively formed on the round structures at the two ends of the drum shaft; and the two ends of the drum shaft are respectively inserted into round holes formed on the brackets at the two ends and matched with the two ends of the drum shaft, and pin shafts are inserted into the pin shaft holes on the round structures at the two ends of the drum shaft for positioning. As the two ends of the drum shaft adopt round structures, the simple installation structure has the advantages of simple structure, easiness in processing and convenience in installation, and the drum shaft can be reliably positioned through the positioning of the round structures at the two ends and the pin shafts without centering, which avoids the problem in the prior art that the centering is difficult, resulting in the derivation of the drum shaft in installation, and improves the reliability and the installation efficiency.
Description
Technical field
The utility model relates to the logistics equipment field, relates in particular to roller conveyor.
Background technology
Roller conveyor generally partly is made up of driving drum, frame, support, drive division etc., be applicable to the conveying of freight all kinds such as all kinds of casees, bag, pallet, be widely used in the airport, the harbour in other logistics disposal systems such as coal mining industry, can be carried the bigger material of single-piece weight and bear bigger impact load, it is big to have operational throughput, speed is fast, and it is brisk to turn round, and can realize the characteristics that the shunting of many kinds conllinear is carried.
Its intermediate roll is mainly used in and drives the circle tube assembly of carrying.The version of rolling can be divided into power drum line and unpowered cylinder line by type of drive, and unpowered roller frame has simple in structure, reliability height, simple installation, advantages such as working service convenience.
At present, unpowered cylinder commonly used is made up of cylinder, drum shaft, both sides support, and described drum shaft runs through the center with cylinder, and the two ends of described drum shaft are processed with screw thread, have tapped bore on the described support, logical bolted connection is fixed the two ends of support and drum shaft.
The structure of this drum shaft and mounting means are by following shortcoming:
(1) need be in the two ends of axle machining screw, process the tapped bore that is cooperated on the support of both sides, the right alignment that in processing and installation process, needs to guarantee institute's machining hole, during installation, the centering complexity, make easily the axle the installation sideslip, influence the operation of cylinder, so this method processing difficulties, installation difficulty are big, the cost height;
(2) in long-term service firing process, because bolted connection is adopted at the drum shaft two ends, easily produce wearing and tearing, make and can produce drum shaft and being connected of support loosening or disengaging, influence alerting ability in the cylinder use, then can influence the operational process of whole roller conveyor, when serious, can cause phenomenons such as stuck in the course of conveying, influence the work efficiency of roller conveyor.
The utility model content
The applicant provides a kind of rational in infrastructure at shortcomings such as above-mentioned existing drum shaft processed complex of the prior art, installation difficulties, the simple and easy mounting structure of the unpowered drum shaft of easy-to-install, thus make processing easy, be easy to install and the location.
The technical scheme that the utility model adopted is as follows:
A kind of simple and easy mounting structure of unpowered drum shaft, comprise cylinder, drum shaft, be installed on the bearing between cylinder and the drum shaft and the support at back-up roller axle two ends, described drum shaft is through the center of cylinder, the two ends of described drum shaft are the round structure, have pin shaft hole on the two terminal circle body of described drum shaft; The circular port that matches that has on two side stands is inserted at the two ends of described drum shaft respectively, inserts the bearing pin location in the pin shaft hole that has on drum shaft two terminal circle body.Its further technical scheme is:
Described bearing pin is the R font.
The beneficial effects of the utility model are: the round structure is adopted at the drum shaft two ends, not only simple in structure, handling ease, easy for installation, can reach the reliable location of drum shaft by the positioning instant of two terminal circle physique structure and bearing pin, need not centering, avoided centering difficulty in the prior art and produce the problem of the installation sideslip of drum shaft, improve reliability and the installation effectiveness of cylinder.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model support.
Fig. 3 is the structural representation of the utility model bearing pin.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
See Fig. 1 and Fig. 2, device described in the utility model comprises cylinder 1, drum shaft 2 and two side stands 3, drum shaft 2 is through the center of cylinder 1, the two ends of drum shaft 2 are the round structure, two side stands 3 have the circular port 6 that matches with the drum shaft two ends, drum shaft 2 two terminal circle physique structure places have and adopt R font bearing pin 4 to insert pin shaft holes 5 location (see figure 3)s after pin shaft hole 5, two side stands 3 are connected with drum shaft 2.
In the actual installation and processing process, the two ends of drum shaft 2 are processed as the round structure, be inserted into the center of cylinder 1, earlier an end of round structure is inserted in the circular hole 6 that a side stand 3 opened, make axle and circular hole finish free-running fit, and cylinder 1 and drum shaft 2 are the level of state, then the other end round structure of drum shaft 2 is aimed at the circular hole of opposite side support 3, and be inserted into, assembling of the present utility model has promptly been finished in the last reliably location of R font bearing pin 4 of inserting in the pin shaft hole 5 at drum shaft two.Location by the two ends bearing pin makes axial location reliable, and the circular port by two side stands makes the diameter of axle reliable to the location.So drum shaft adopts the two terminal circle physique structure, and it is easy promptly to reach processing, and installing and locating is reliable.
More than describing is to explanation of the present utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of spirit of the present utility model, the utility model can be done any type of modification.
Claims (2)
1. the simple and easy mounting structure of a unpowered drum shaft, comprise cylinder, drum shaft, be installed on the bearing between cylinder and the drum shaft and the support at back-up roller axle two ends, described drum shaft is through the center of cylinder, it is characterized in that: the two ends of described drum shaft are the round structure, have pin shaft hole on the two terminal circle body of described drum shaft; Insert respectively in the circular port that matches that has on two side stands at the two ends of described drum shaft, inserts the bearing pin location in the pin shaft hole that has on drum shaft two terminal circle body.
