Description
Technical field
The utility model relates to drag conveyor inner guide pulley technical fields, and in particular to a kind of inner guide pulley machine of adjustable axial length
Structure.
Background technique
Drag conveyor is widely used in coal dust bottom slag transportation system, and inner guide pulley is the weight of drag conveyor transmission system
Component is wanted, guiding is provided and is supported for chain and scraper plate.The inner guide pulley of general type is all bolted, and is fixed to scraper plate and conveys
On pusher side wall, and contact surface has rubber strip sealing, and in use for some time, casing inner width may be due to object for drag conveyor
The reasons such as the impact and thermal deformation of material, size change；Or during processing and manufacturing, existing manufacture level makes casing
Inner width is larger with design deviation, and the precision of design code is not achieved；Above two reason will lead to after inner guide pulley installation, and two
Center between inner guide pulley can generate deviation, this deviation meeting away from design requirement, drag conveyor is unsatisfactory in the process of running
Aggravate the abrasion between guide wheel and chain, scraper plate, reduces the service life of equipment.
The measure of existing adjusting center distance is substantially: dismantling inner guide pulley again, the cushioning rubber pad or again at contact surface
The thickness of secondary turner, then installed.This mode is time-consuming and laborious, and precision can not be completely secured after installing again；
Dismantle inner guide pulley, it is also necessary to which the operation for stopping drag conveyor influencing the continuity of system work；If casing internal has dirt
Water then also results in sewage and flows out from the guide wheel hole after disassembly, pollutes environment.
Utility model content
The purpose of this utility model is and to provide a kind of the interior of adjustable axial length for technological deficiency existing in the prior art
Guide wheel mechanism.
It is for technical solution used by realization the purpose of this utility model:
A kind of inner guide pulley mechanism of adjustable axial length, including inner guide pulley and the external screw thread bearing being connect with the inner guide pulley
Case, the external screw thread bearing housing are threadedly coupled by the internal screw thread of its external screw thread and Internal thread flange disk, the internal screw thread method
Blue disk is connected on the casing of drag conveyor.
The Internal thread flange disk is bolt-connected on the casing of drag conveyor.
It is wound with sealing joint strip in the thread joint face of the external screw thread bearing housing and Internal thread flange disk, to prevent sewage
It is leaked from thread joint face.
The center of the external screw thread bearing housing has stair-stepping axis hole, and the axis of the inner guide pulley passes through the axis hole and leads to
It crosses bearing part to connect with the external screw thread bearing housing and external bearing housing, the other end of the axis connects guide wheel body, described outer
Screw thread bearing housing is bolted with external bearing housing.
End cap is bolted in the external bearing housing.
The utility model may be implemented after inner guide pulley installs sealing, without dismantling and stopping drag conveyor fortune again
Row can be achieved with the axial dimension for adjusting inner guide pulley, to compensate casing inner width change in size caused by a variety of causes, to guarantee
Two inner guide pulley centers are away from size constancy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the inner guide pulley of adjustable axial length；
Fig. 2 is the schematic diagram of Internal thread flange disk；
Fig. 3 is the big schematic diagram of external screw thread bearing housing；
The schematic front view of the inner guide pulley for axial length that Fig. 4 is adjustable.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Referring to shown in Fig. 1-4, a kind of inner guide pulley of adjustable axial length, comprising:
Inner guide pulley 100, external screw thread bearing housing 1, Internal thread flange disk 2, the inner guide pulley 100 pass through bolt 14 and spiral shell
Keyhole 12 is connected on external screw thread bearing housing 1, and the Internal thread flange disk 1 is bolt-connected to the casing of drag conveyor
On, the contact surface pad rubber strip sealing with drag conveyor；External screw thread bearing housing 1 and Internal thread flange disk 2 pass through regular screw threads
Connection, external screw thread bearing housing 1 have external screw thread 11, and Internal thread flange disk 2 has internal screw thread 22, and the joint face of the two winds band,
Playing can to adjust screw thread mobile and prevent sewage from leaking from flank for front and back.
Wherein, the Internal thread flange disk is connected to the casing of drag conveyor by connection bolt 23 and bolt hole 21
On 200.
Wherein, sealing joint strip is wound with (not in the external screw thread bearing housing 1 and the thread joint face of Internal thread flange disk 2
Show), to prevent sewage from leaking from thread joint face.
Wherein, the center of the external screw thread bearing housing has stair-stepping axis hole 13,110 institute of guide wheel body of the inner guide pulley
Connecting shaft 120 passes through the axis hole 13, and respectively by a bearing part 130 and the external screw thread bearing housing 1 and outer wall
The external bearing housing 140 for being connected with lubricating cup connects, and the other end of the axis connects guide wheel body 110, the external screw thread bearing housing with
External bearing housing is connected by bolt 14.
Wherein, the external bearing housing connects the end cap 150 of bearing housing by bolt 160, the external screw thread bearing housing 1 with
There are shaft packing 15 or shaft seal between axis, to play the sealing function and function between axis and external screw thread bearing housing 1.
When inner guide pulley is installed on drag conveyor side wall, whether the operation of observation drag conveyor is put down in the process of running
Surely, and according to the needs of actual state with the external screw thread bearing housing 1 of large-scale spanner rotation inner guide pulley it is allowed to and internal screw thread method
Relative displacement occurs for blue disk 2, plays the function of adjusting at any time, to can guarantee guide wheel center away from constant.
The utility model has the following beneficial effects:
1, without dismantling inner guide pulley, i.e., the center of adjustable guide wheel is away from avoiding the sewage of casing internal from outflowing.
2, without shutting down, i.e., the center of adjustable guide wheel is away from avoiding drag conveyor shutdown from causing material conveying pause, protect
The continuous sex work of system is hindered.
3, inner guide pulley screw thread adjusting center distance, precision are relatively high.
4, the utility model is not high to the required precision of casing inner width, and there is a certain error for permission, can reduce casing
The difficulty of welding processing, improves working efficiency indirectly.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
