Abstract
The utility model provides a belt type non-return device for a belt conveyor. The belt type non-return device comprises a fixing rack and a brake belt. One end of the brake belt is fixedly connected onto the fixing rack, and the other end of the brake belt extends outwards from the fixing rack. When the fixing rack is fixed onto a framework of the belt conveyor, the brake belt downwards droops on a conveying belt of the belt conveyor. The belt type non-return device is simple in structure, low in cost and convenient to install, and is manufactured easily, and a non-return effect of an existing mechanical non-return device can be improved when the belt type non-return device is used with the existing mechanical non-return device.
Description
Technical field
The utility model relates to a kind of holdback that is used for belt conveyer, relates to a kind of belt holdback particularly.
Background technology
Belt conveyer is coal preparation plant's transportation device commonly used, plays an important role in process of production.Usually the belt conveyer that has the inclination angle can be because of equipment or the anxious phenomenon of stopping of other problem generation in operational process; Therefore the coal that causes transporting on the belt conveyor of belt conveyer is along with belt conveyor together slides into tail; Not only increase operator's labour intensity, and caused the certain resource and the waste of labour power.
In order to avoid the generation of this type of accident as far as possible, when the belt conveyer Selection and Design, require on reductor high speed shaft or slow-speed shaft, to install a mechanical type holdback usually.The main effect of machinery holdback is only to allow conveyer toward the fixed-direction operation, allows head roll freely to rotate in working direction, but can prevent the driving drum backward rotation automatically.Common mechanical holdback has roller holdback, contactless holdback, contact wedge backstop or the like; Mostly its principle of work be through the coaxial inner ring in holdback set inside one and outer ring, when the backwards rotation of outer ring, produces friction force by inner ring or produce resistance to suppress the outer ring and rotate and realize, therefore; This type of holdback is behind repeated use; Damage easily, especially on large inclination belt conveyor, breakdown speed is faster.This has not only increased work capacity, influences the ordinary production tissue, but also has increased productive costs.
The utility model content
In order to solve the problem that the existing machinery holdback damages easily; The utility model provides a kind of belt holdback that is used for belt conveyer to assist the work of existing machinery holdback; Said belt holdback comprises: fixed mount and brake collar; Brake collar one end is fixedly connected on the fixed mount, and the other end stretches out from fixed mount.
Fixed mount is used for fixing on the frame of said belt conveyer, so that brake collar lets droop on the belt conveyor of belt conveyer.Preferably, fixed mount is the column alloy steelframe that the bottom has screw, is installed near the belt-driven cylinder of belt conveyer.The length that brake collar extends out from fixed mount is 1/2nd to times of girth of the belt-driven cylinder of belt conveyer, and preferably, brake collar is terylene adhesive tape or rubber adhesive tape.
The belt holdback that the is used for belt conveyer manufacturing simple in structure, easy that the utility model provided, cost is low and easy for installation; When using jointly with the existing machinery holdback; Not only can improve the non-return effect of existing machinery holdback, but also be easy to change.So not only guaranteed the safe handling of belt conveyer, also prolonged the service life of existing machinery holdback, and its cheap manufacturing cost can't increase the extra maintenance expense of existing machinery holdback.
Description of drawings
Fig. 1 is the structural representation of the belt holdback that is used for belt conveyer in the utility model;
Fig. 2 is the running condition figure of belt holdback shown in Figure 1.
The specific embodiment
To combine accompanying drawing below; Describe the embodiment of the utility model, be used for the belt holdback of belt conveyer shown in Fig. 1, this holdback comprises the fixed mount 1 and brake collar 2 that the column alloy steel is processed; Brake collar 2 is wrapped on the fixed mount 1, and purpose is fixing said brake collar 2.Fixed mount 1 is installed on the frame of belt conveyer with being used for fixing, and brake collar 2 is hung down to the belt conveyor of belt conveyer downwards naturally.
In the embodiment of the utility model, fixed mount 1 has the column alloy steelframe of screw for the bottom, and the bottom screw is used for through the mode that is spirally connected fixed mount 1 being fixed on frame, certainly, also can adopt other known fixed form with certain intensity.Selecting the material of alloy steel as the fixed mount 1 of making the belt holdback for use, is in order to guarantee that fixed mount 1 itself can bear the thrust and the tensile force of brake collar 2, makes brake collar 2 constant relatively about the attachment point of frame.Certainly, fixed mount 1 can also adopt other known form except adopting said structure with the material, as long as guarantee fixing an end of brake collar 2.The installation site of fixed mount 1 need be looked concrete applied environment and confirm; Consider the parameters such as operational throughput, leaning angle and delivery speed of applied belt conveyer; Basically; Guarantee to make brake collar 2 as early as possible with belt conveyor contact belt-driven cylinder and with its braking the anxious belt conveyor that stops taking place when driving in the wrong direction.Preferably, fixed mount 1 is installed near the belt-driven cylinder 11 (Fig. 2 illustrates) of belt conveyer.
It will be appreciated by those skilled in the art that; According to concrete applied environment; For the conveyer of different operational throughpuies, leaning angle, delivery speed, the length of brake collar 2, width, thickness and material all can change, and these attributes of brake collar 2 have also determined braking time.
Fig. 2 illustrates the running condition of belt holdback.Wherein, belt conveyor 10 is around 11 operations of belt-driven cylinder, and service direction is a direction shown in the arrow A.Fixed mount 1 is fixed on the frame of belt conveyer, and brake collar 2 is hung down on a side of belt conveyor 10.When belt conveyor 10 moved with direction A, because fixed mount 1 is fixing, brake collar 2 did not hinder the motion of belt conveyor 10, because when high-speed cruising, because belt conveyor 10 caused air motions, the free end of brake collar 2 roughly is the shape that suspends.In case and the drive system et out of order of belt conveyer; Belt conveyor 10 is with antikinesis; Promptly in contrast to direction A, at this moment, brake collar 2 will be with belt conveyor 10 towards 11 motions of belt-driven cylinder; And then be involved between head roll 11 and the belt conveyor 10, thereby utilize rubbing effect with head roll 11 brakings.In this embodiment, the length that brake collar 2 extends out from fixed mount is girth half the of head roll 11, can be involved in rapidly and brake.
That the belt holdback that is used for belt conveyer in the utility model is made is simple, with low cost, carry and change conveniently, can effectively assist existing holdback to prevent that conveyer from reversing.
