Abstract

The invention belongs to the technical field of mining machinery and discloses a hydraulic five-wheel tensioning device which comprises a vertical fixed frame, two guide wheels, two double guide wheels, three fixed pulleys, two movable pulleys and hydraulic cylinders. The two guide wheels are mounted on two sides of the fixed frame respectively, the two double guide wheels are mounted on the top of the fixed frame, the three fixed pulleys and the two movable pulleys are arranged on one face of the fixed frame and in transverse alternate arrangement, and the guide wheels, the fixed pulleys and the movable pulleys are flexibly connected through a traction steel wire rope. The hydraulic cylinders are arranged on the other face of the fixed frame, each movable pulley and the corresponding hydraulic cylinder are flexibly connected through a connection steel wire rope which bypasses the corresponding double guide wheel. The hydraulic five-wheel tensioning device has the advantages that labor intensity is relieved for workers, and production and transport cost is reduced. Further, tensioning force of the device can be changed at any time only by changing the pressure of a hydraulic system, the hydraulic five-wheel tensioning device is convenient to operate, laborsaving and timesaving, and more reliable and larger tensioning force can be provided.

Description

A kind of hydraulic pressure five is taken turns tightening device

Technical field

The present invention relates to a kind of hydraulic pressure five and take turns tightening device, belong to the mining machinery technical field.

Background technology

The haulage cable of endless rope winch, rope traction road railer, rope traction monorail crane etc. can produce deformation in the situation of tension, the pulling force difference be load not simultaneously, the distortion of its generation is that stretched length is also different, therefore just requires a kind of device can absorb the length of haulage cable stretching and the stretched length that can automatically regulate absorption.As shown in Figure 2, prior art is commonly weight five and takes turns tightening device, and it adopts the mode of weight to absorb the distortion of haulage cable, because the reliability of physical construction, this device has adopted decades, therefore never has substitute.But, at first weight five take turns tightening device produce, during transportation, the counterweight of employing all needs a dead lift, goes into the well when installing, also needing has manually increased workman's labour intensity and productive costs with the installing on the tightening device of one one of counterweight; Secondly, when tensile force need to change, can only regulate by the quantity of manual change's counterweight, time-consuming; In addition, be subjected to the restriction of counterweight volume and have maximum tensile force to limit, when the larger tensile force of needs, can only change the structure of device.Meanwhile, along with the development of hydraulic technique, Hydranlic tensioner is accepted by a lot of equipment and is used, and the proven technique application has been arranged.

Summary of the invention

For above-mentioned existing technical matters, the invention provides a kind of hydraulic pressure five and take turns tightening device, time saving and energy saving to arrive, easy to operate and the purpose of more reliable, larger tensile force is provided.

The present invention for achieving the above object, be achieved through the following technical solutions: a kind of hydraulic pressure five is taken turns tightening device, the fixed frame that comprises vertical placement, be installed in respectively two track adjusting wheels of fixed frame both sides, be installed in respectively two two track adjusting wheels of fixed frame top margin, be placed on three fixed pulleys and two movable pulleys of fixed frame one side, and the horizontal alternative arrangement of fixed pulley and movable pulley, track adjusting wheel, be flexible coupling by a haulage cable between fixed pulley and the movable pulley, also comprise the hydraulic ram that is placed on the fixed frame another side, be flexible coupling by connecting steel wire ropes between corresponding movable pulley and the hydraulic ram, and two track adjusting wheels corresponding to connecting steel wire ropes difference pile warp.

The invention has the beneficial effects as follows: at first, adopt hydraulic ram can effectively reduce the weight of counterweight, and then reduce workman's labour intensity and the cost of production and transport.Secondly, only need to change the just tensile force of modifier at any time of hydraulic system pressure, easy to operate, saving of work and time.In addition, only need to improve hydraulic system pressure and the structure that need not modifier, more reliable and larger tensile force can be provided.

Description of drawings

Fig. 1 is the structural representation that hydraulic pressure five of the present invention is taken turns tightening device;

Fig. 2 is the structural representation that weight five is taken turns tightening device in the prior art.

Among the figure: 1, haulage cable, 2, track adjusting wheel, 3, fixed pulley, 4, movable pulley, 5, two track adjusting wheel, 6, connecting steel wire ropes, 7, hydraulic ram, 8, fixed frame, 9, counterweight.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

As shown in Figure 1, the present invention includes the fixed frame 8 of vertical placement, be installed in respectively two track adjusting wheels 2 of fixed frame 8 both sides, be installed in respectively two two track adjusting wheels 5 of fixed frame 8 top margins, be placed on three fixed pulleys 3 and two movable pulleys 4 of fixed frame 8 one sides, and fixed pulley 3 and movable pulley 4 horizontal alternative arrangements, track adjusting wheel 2, be flexible coupling by a haulage cable 1 between fixed pulley 3 and the movable pulley 4, also comprise the hydraulic ram 7 that is placed on fixed frame 8 another sides, be flexible coupling by connecting steel wire ropes 6 between corresponding movable pulley 4 and the hydraulic ram 7, and two track adjusting wheels 5 corresponding to connecting steel wire ropes 6 difference pile warps.

Further, five take turns three fixed pulleys 3 of finger and two movable pulleys 4; Fixed frame 8 is mainly used in stator wheel 2, two track adjusting wheel 5 and hydraulic ram 7, and guiding is provided when also can be used for sliding for movable pulley 4 tensionings.

During enforcement, haulage cable 1 can produce deformation in the different situation of load, track adjusting wheel 2 accesss to plant that it takes turns the tightening device both sides by hydraulic pressure five are inner, its two ends and midway location are fixing by three fixed pulleys 3 respectively, when hydraulic ram 7 is upwards strained movable pulley 4 by connecting steel wire ropes 6 and two track adjusting wheel 5, just strained because load produces the haulage cable 1 of deformation.Because different equipment is different for the requirement of tensile force, therefore need tightening device that very large setting range is arranged, when satisfying distinct device to the different needs of tensile force, a hydraulic system pressure that only needs to regulate this device hydraulic ram 7 gets final product, easy to operate, saving of work and time.
