Background

Along with the automation degree of ports, various grain processing enterprises and various grain logistics transfer centers is higher and higher, the use of conveying equipment is wider and wider. The current trend is that conveying equipment develops towards long-distance high-yield direction, when equipment is conveyed for long distance and high-yield, chain breakage possibly occurs to chains in the equipment because of insufficient strength, or chain breakage occurs to the chains due to foreign matters mixed in materials, if equipment is easy to damage after chain breakage if the equipment continues to operate, the development of chain breakage protection structures on the equipment is promoted.

General chain rupture detection is the speed measurement switch warning of equipment afterbody in original trade, when the inside chain of equipment broke, equipment continues the operation, only break away from equipment head sprocket (drive sprocket) completely when chain rupture department leads to equipment afterbody sprocket (driven sprocket) not to change, perhaps break away from equipment afterbody sprocket (driven sprocket) completely when chain rupture department, afterbody sprocket does not change, the speed measurement switch of equipment tail installation can not detect signal alarm, these two kinds of circumstances are the chain rupture back, equipment operation leads to equipment to appear damaging easily, consequently, it is necessary to increase chain rupture protection device on equipment.

SUMMERY OF THE UTILITY MODEL

Need just can report an alarm after overcoming current equipment chain broken chain and shut down not enough in a section reaction time, the utility model provides a supporting broken chain protection architecture of conveying equipment, through set up the sprocket dish that takes speed switch on equipment length direction and come the solution problem.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a supporting chain rupture protection architecture of conveying equipment, sets up in conveying equipment's chain, includes driven sprocket, supporting component and speed measuring component, and driven sprocket erects between the supporting component at both ends through its central supporting shaft, still is provided with the speed measuring component who is used for the chain rupture warning on the supporting component of one end wherein, and driven sprocket and chain mesh transmission.

Furthermore, the driven chain wheel comprises a chain wheel disc arranged on the supporting shaft in a penetrating mode, clamping sleeves arranged on two sides of the chain wheel disc and fasteners arranged on the clamping sleeves, and the clamping sleeves are symmetrically arranged on two sides of the chain wheel disc through the fasteners.

Further, the support component is a bearing seat with a bearing arranged at the end part of the support shaft.

Furthermore, a bearing protective cover used for ensuring the use safety is arranged on the periphery of the bearing seat.

Furthermore, the inner side surface of the bearing seat is provided with a sealing plate for sealing, and the sealing plate is connected with the bearing seat through a bolt.

Further, the speed measuring component comprises a speed measuring disk arranged at the end part of the supporting shaft and a speed measuring switch arranged on the periphery of the speed measuring disk.

The utility model has the advantages that the alarm time can be further shortened when chain breakage occurs in the equipment by increasing the number of the chain breakage protection devices on the length of the equipment, the chain breakage position can be quickly found for maintenance, and the maintenance work efficiency is improved; only the chain wheel disc and the chain are meshed consistently during installation, and the chain wheel disc has the characteristics of low cost, simple structure, good sealing performance, good use effect, long service life and the like.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic structural view of the driven sprocket;

fig. 3 is a schematic structural view of the bearing housing.

In the figure, 1, a support shaft, 2, a chain wheel disc, 3, a clamping sleeve, 4, a fastener, 5, a bearing seat, 6, a bearing protective cover, 7, a sealing plate, 8, a speed measuring disc and 9, a speed measuring switch are arranged.

Detailed Description

If fig. 1 is the utility model discloses a structural schematic diagram, a supporting chain rupture protection architecture of conveying equipment sets up in conveying equipment's chain, including driven sprocket, supporting component and speed measuring component, driven sprocket erects between the supporting component at both ends through its central back shaft 1, still is provided with the speed measuring component who is used for the chain rupture warning on the supporting component of one end wherein, driven sprocket and chain meshing transmission. During installation, the chain wheel disc 2 is meshed with the chain uniformly to complete installation.

The speed measuring component comprises a speed measuring disk 8 arranged at the end part of the supporting shaft 1 and a speed measuring switch 9 arranged on the periphery of the speed measuring disk 8. The traditional mode that the chain of the equipment needs a period of reaction time to alarm and stop after chain breakage is changed into the mode that the chain breakage protection device alarms and stops in a short time after the chain of the equipment is broken.

Driven sprocket installs on back shaft 1, and the normal operating of bearing frame 5 assurance driven sprocket is placed at the axle both ends, and driven sprocket outside is placed and is tested the speed dish 8 and report to the police with the switch 9 that tests the speed, and when equipment normal operating, driven sprocket and chain together move, when the chain broken chain appears, breaks away from driven sprocket in the department of chain broken nearby, driven sprocket stall, and outside switch 9 that tests the speed reports to the police.

This chain breakage protection architecture is by sprocket disc 2, back shaft 1, closing plate 7, bearing frame 5, the disk 8 tests the speed, speed measuring switch 9, bearing protection casing 6 constitutes, supporting various conveying equipment, can realize that the switch sends alarm signal when the chain breaks in equipment, can set up this chain breakage protection architecture of multiunit on equipment length direction, but the warning shut down in the short time when the chain breaks in somewhere, simultaneously according to chain breakage protection device alarm position lock chain breakage position rapidly in time change the chain and do not influence normal equipment production, the chain is broken suddenly when having solved equipment operation from this, equipment continues to operate and causes the problem of damage for equipment, the work efficiency of maintenance has been improved, can guarantee equipment leakproofness simultaneously and prevent that the dust from spilling over.

As shown in fig. 2, the driven sprocket comprises a sprocket wheel disc 2 arranged on a supporting shaft 1 in a penetrating mode, clamping sleeves 3 arranged on two sides of the sprocket wheel disc 2 and fasteners 4 arranged on the clamping sleeves 3, wherein the clamping sleeves 3 are symmetrically arranged on two sides of the sprocket wheel disc 2 through the fasteners 4.

Sprocket dish 2 is fixed the setting on back shaft 1 through the clamping sleeve 3 of its both sides to utilize fastener 4 to fix clamping sleeve 3, fastener 4 generally adopts hexagon bolt, and the bolt of screwing supports the surface that back shaft 1 and can carry on spacingly to sprocket dish 2.

As shown in fig. 3, the supporting component is a bearing seat 5 with a bearing arranged at the end of the supporting shaft 1, so as to ensure the normal operation of the chain breakage protection device.

The periphery of the bearing seat 5 is provided with a bearing protective cover 6 for ensuring the use safety, so that the man-machine safety is protected.

The inner side surface of the bearing seat 5 is provided with a sealing plate 7 for sealing, and the sealing plate 7 is detachably connected with the bearing seat 5 through a bolt, so that the sealing reliability of the equipment during operation is ensured.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
