Abstract
The utility model discloses a tension device for a scraper feeder. The tension device comprises a hydraulic cylinder, and a hydraulic cylinder body is connected with a sliding bearing block of a tail wheel unit. The tension device is characterized by further comprising a mounting base fixed on a scraper feeder rack, a through hole is opened in the mounting base, and a hydraulic cylinder piston rod penetrates the hole in the mounting base. A pressure plate is fixed at the front end of the hydraulic cylinder piston rod, and a pressure sensor is arranged between the pressure plate and the mounting base and is connected with a controller which is connected with a hydraulic control station driving the hydraulic cylinder. According to the tension device, the tension is accurate, tension changes of the scraper feeder during the whole operation can be reflected visually, the device is convenient to maintain and capable of saving maintenance time and suitable for intelligence of heavy large-pitch bilateral-chain type scraper feeders.
Description
Technical field
The utility model relates to a kind of tightening device for scraper feeder, especially a kind of tightening device that can automatically regulate according to operating mode.
Background technology
At present, in slat conveyer manufacturing, to the tensioning of chain, be all to rely on to drive the hydraulic actuating cylinder or the spiral tightening device that are connected with tail wheel plain bearing housing to carry out with loosening.The degree of tightness of chain cannot accurately be located, be generally to lean on operative employee's experience to judge, these artificial judgements also have many wrong diagnosis, and the safe operation of scraper plate feed is caused to unnecessary shutdown, thereby increase maintenance cost, causes economic loss to production; In feeder work, the tightness of chain is breezy relevant to safe operation, and chain is excessively loose, can cause that annular chains skids, sideslip and freight volume reduce out of reach designing requirement; Chain tension, can make running current increase and the parts wear of motor too fast, increases maintenance cost, with also greatly having affected production.
Utility model content
For the technical matters of above-mentioned existence, the utility model provides a kind of scraper feeder tightening device, can accurately test out tension force that chain bears according to circumstances suitable adjusting.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A scraper feeder tightening device, comprises hydraulic actuating cylinder, and described hydraulic cylinder body is connected with the plain bearing housing of tail-pulley device; It is characterized in that: also comprise a mount pad being fixed in scraper feeder frame, on described mount pad, have the hole of running through; Described hydraulic cylinder piston rod runs through the hole on mount pad; Hydraulic cylinder piston rod front end is fixed with pressure plate, between described pressure plate and mount pad, is provided with pressure sensor; Described pressure sensor is connected with controller; Described controller is connected with driving the fluid control station of hydraulic actuating cylinder.
As a kind of improvement, on described hydraulic cylinder piston rod, being positioned at pressure plate front end sleeve has adjustment bearing, and relies on nut to be pressed on pressure plate.Can prevent that piston rod from radially wobbling.
As a kind of preferred, described controller is PLC controller or controls computer.
As a kind of improvement, on described controller, be connected with telltale and operator's station.In the time of necessary, facilitate manual operation.
Usefulness of the present utility model is: regulate and compare with hydraulic actuating cylinder with traditional adjustable diameter and screw adjusting, the tension force that the utility model provides is more accurate, can intuitively reflect that scraper feeder is in the operating tension variation of whole process, easy to maintenance, can save maintenance time, be more suitable for the intellectuality of the bilateral scraper chain conveyer of heavy coarse pitch.Intensive, high strength exploitation at Coal Industry simultaneously meets higher requirement, the important channel that greatly raise labour productivity, save investment, reduces production costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 pressure sensor, 2 pressure plates, 3 are adjusted bearing, 4 hydraulic actuating cylinders, 5 mount pads, 6 frames, 7 plain bearing housings, 8 fluid control stations, 9 controllers, 10 telltales, 11 operator's stations.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1:
The utility model comprises the hydraulic actuating cylinder 4 being driven by fluid control station 8, and described hydraulic actuating cylinder 4 cylinder bodies are connected with the plain bearing housing 7 of tail-pulley device; Also comprise a mount pad 5 being fixed in scraper feeder frame 6, on described mount pad 5, have the hole of running through; Described hydraulic actuating cylinder 4 piston rods run through the hole on mount pad 5; Hydraulic actuating cylinder 4 piston rod front ends are fixed with pressure plate 2, between described pressure plate 2 and mount pad 5, are provided with pressure sensor 1; Described pressure sensor 1 is connected with controller 9; Described controller 9 is connected with driving the fluid control station 8 of hydraulic actuating cylinder 4.On hydraulic actuating cylinder 4 piston rods, being positioned at pressure plate 2 front end sleeves has the bearing 3 of adjustment, and relies on nut to be pressed on pressure plate 2.Controller 9 can or be controlled computer for PLC controller, can also be connected with telltale 10 and operator's station 11 on controller 9.
By contraction or diastole hydraulic actuating cylinder 4, pull plain bearing housing 7, in order to adjust the tensile force of chain.Pressure plate 2 and 5 pairs of pressure sensors of mount pad are executed 1 pressure simultaneously, and its force value is equal to the tension force that chain bears.Tension force numerical value is fed back to controller 9, by controller 9 automatic decisions, should be tightened up or diastole, and drive 8 work of fluid control station, complete adjustment.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; 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 protection domain of the present utility model.
