Abstract
The utility model discloses a wire rope hydraulic cylinder tensioning device. One end of a wire rope is connected with a driving device, and the other end of the wire rope is connected with a towed object. The device comprises a hydraulic cylinder, a movable pulley and a fixed pulley, wherein both the fixed pulley and the hydraulic cylinder are fixed on an operating platform, the movable pulley is connected with the piston rod of the movable pulley and moves with the piston rod, and the wire rope passes through the movable pulley and the fixed pulley. The wire rope hydraulic cylinder tensioning device adopts the hydraulic device to automatically tension the wire rope according to different lengths of the wire rope during operation. The device has simple and compact structure and low cost, and is convenient in mounting and maintenance.
Description
Technical field
The utility model belongs to steel wire rope stretching device, is specifically related to a kind of steel rope hydraulic actuating cylinder tightening device.
Background technology
Rope traction equipment is usually used in fields such as mechanical execution, loading and unloading goods, comprises rope traction equipment, steel rope, is pulled object, and rope traction device drives steel rope is being pulled movement of objects to destination locations.Because steel rope is flexible transmission device, can the actv. transmission for exerting all one's strength by steel rope, must keep steel rope in tension all the time, this just needs steel wire rope stretching device.For example the applicant designs the Winch-driven moveable baseboard dumper of producing and applying for a patent, the patent No. is 200920291157.9, a kind of Winch-driven moveable baseboard dumper is disclosed, the design plan that this car adopts is, the compartment is arranged on the main car frame of chassis, subframe and hydraulic lifting system have been exempted, car load is designed to the compartment and maintains static, the compartment header board is designed to movable push, employing drags the unloading mode that the compartment header board moves backward by movable base plate, by the firm and hard movably existing unloading of capstan driving device pulling, capstan driving device is exactly a kind of rope traction equipment, drives the movable base plate motion by rope traction compartment header board.
Summary of the invention
The purpose of this utility model is, a kind of steel rope hydraulic actuating cylinder tightening device is provided, this apparatus structure compactness, simple to operate, and at the bottom of the manufacturing cost, I﹠M is convenient, high efficiency.
The steel rope hydraulic actuating cylinder tightening device that the utility model provides, steel rope one end connects actuating device, other end connection is pulled object, this device comprises hydraulic actuating cylinder, movable pulley, quiet assembly pulley, described quiet assembly pulley, hydraulic actuating cylinder are fixedly installed on the workplatform respectively, movable pulley is connected with the piston rod of hydraulic actuating cylinder, and with piston rod movement, steel wire penetrating movable pulley and quiet assembly pulley.It also comprises pull back spring, and described pull back spring is arranged in the bar chamber of hydraulic cylinder piston rod.
The steel rope hydraulic actuating cylinder tightening device that the utility model provides, its beneficial effect are, adopt hydraulic efficiency gear, and the different length when working according to steel rope is to the enforcement auto-tensioning of steel rope.This apparatus structure is simple, compact, at the bottom of the cost, I﹠M is convenient.
Description of drawings
Fig. 1 is the integral structure scheme drawing of an embodiment of the utility model.
Mark among the figure:
1. cabin floor; 2. compartment push pedal; 3. rubber plate belt conveyor; 4. steel rope; 5. hydraulic actuating cylinder; 6. movable pulley; 7. quiet assembly pulley; 8. head roll.
The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the steel rope hydraulic actuating cylinder tightening device that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1, the steel rope hydraulic actuating cylinder tightening device of present embodiment, be arranged on bottom, Winch-driven moveable baseboard dumper compartment, this device comprises hydraulic actuating cylinder 5, movable pulley 6, quiet assembly pulley 7, steel rope 4 one ends connect head roll 8, the other end is walked around assembly pulley and is connected compartment push pedal 2, quiet assembly pulley 7, hydraulic actuating cylinder 5 are fixedly installed on respectively on the cabin floor 1, movable pulley 6 is connected with the piston rod of hydraulic actuating cylinder 5, and with piston rod movement, it also comprises pull back spring, and described pull back spring is arranged in the bar chamber of hydraulic cylinder piston rod.Because the winding radius of rubber plate belt conveyor 3 and steel rope 4 is different, so in head roll 8 rotary courses, steel rope 4 does not wait with the collapsing length of rubber plate belt conveyor 3, by the flexible difference of replenishing between the two of hydraulic actuating cylinder, thus keep the steel rope in tension and make steel rope 4 and rubber plate driving band 3 between actv. carry out the transmission of power.
Claims (1)
