Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model pulley bracket assembly;
Fig. 3 is use principle figure of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of sister block mechanism for high-pressure rubber pipe as shown in Figure 1, comprise pulley assembly and pulley bracket assembly, pulley bracket assembly comprises the pulley bracket 1 being used for fixing pulley and the cylinder bracket 2 being used for connecting oil cylinder, the diameter that pulley assembly comprises first, second, third, fourth pulley 3,4,5,6, first, second, third, fourth pulley 3,4,5,6 be set up in parallel between two is 60mm.
Further, as shown in Figure 2, pulley bracket 1 comprises between first, second, third plate 11,12,13, first, second, third plate 11,12,13 that is arranged in parallel successively in vertical and linking into an integrated entity by supporting round steel 7, and cylinder bracket 2 is fixed on the below of the second plate 12.
Preferably, the end face of the second plate 12 is higher than the end face of the first, the 3rd plate 11,13.The height of the second plate is higher than the advantage of the first, the 3rd plate: can by fixing for sebific duct fender bracket 10 on the second plate, thus protection high-pressure rubber pipe does not come off from pulley.
Further, pulley assembly comprises first, second pulley 3,4 be disposed in parallel between first, second plate 11,12 and the 3rd, the 4th pulley 5,6 be disposed in parallel between second, third plate 12,13, the first, the 3rd pulley 3,5 is coaxially arranged, and the first, the 3rd pulley 3,5 is connected on pulley bracket 1 by the first bearing pin 8, the second, the 4th pulley 4,6 is coaxially arranged, and the second, the 4th pulley 4,6 is connected on pulley bracket 1 by the second bearing pin 9.Namely using first, second pulley as an assembly pulley, 3rd, the 4th pulley is made an assembly pulley to replace original two major diameter pulleys, both the motion bending spring needed for high-pressure rubber pipe can have been ensured, also effectively can reduce the height of pulley bracket, reduce taking up room of whole mechanism.These two assembly pulleys can be arranged in juxtaposition in cylinder head position, reduce the impact on the free lifting altitude of forklift door frame and the driver visual field.
Preferably, first, second, third, fourth pulley 3,4,5,6 is respectively double grooved pulley.The benefit of double grooved pulley is adopted to be: can be arranged in a pulley by two high-pressure rubber pipes, replace two single-sheaved blocks with a double grooved pulley, effectively reduce the space that pulley takies.
Further; the top of pulley bracket 1 is provided with the sebific duct fender bracket 10 preventing sebific duct from coming off; sebific duct fender bracket 10 entirety is in square frame shape; the centre portion of sebific duct fender bracket 10 is connected with the second plate 12, the two ends of sebific duct fender bracket 10 downward bending being connected on the outer panel face of the first, the 3rd plate 11,13 respectively.
As shown in Figure 3, during installation, pulley bracket assembly is connected with oil cylinder 100 by cylinder bracket 2, and high-pressure rubber pipe is placed on two assembly pulleys, and prevents high-pressure rubber pipe on the go from coming off by sebific duct fender bracket 10.Structurally, the first, the 3rd plate is all coated by chain 200, efficiently solves the problem of chain releasing simultaneously.
The beneficial effects of the utility model are: (1) this mechanism reduces the height of whole pulley bracket assembly, meet the full free height demand of forklift door frame; (2) horizontal direction that this mechanism reduces whole pulley bracket assembly takes up room, and ensures the driver operation visual field; (3) this mechanism ensure that the bending spring needed for high-pressure rubber pipe motion, extends the service life of high-pressure rubber pipe; (4) this mechanism ensure that the required friction force that to be synchronized with the movement between sebific duct and pulley effectively, avoids there is relative motion between pulley and high-pressure rubber pipe, wearing and tearing sebific duct surface; (5) this structure structure is simple, cost is low, reasonable in design, safe and reliable; (6) structure of this mechanism inherently effectively can be protected chain.
In sum, the utility model replaces 2 original major diameter pulleys by adopting the reasonable Arrangement of 4 minor diameter biserial pulleys, both the bending spring needed for high-pressure rubber pipe motion had been met, the horizontal direction of the height and whole mechanism that simultaneously also effectively reduce whole mechanism takes up room, ensure that the complete free lifting altitude needed for forklift door frame and the driver visual field, two minor diameter biserial pulley structures are simple simultaneously, cost is low, larger with high-pressure rubber pipe contact surface, can effectively ensure the required friction force that is synchronized with the movement between sebific duct and pulley, avoid there is relative motion between pulley and high-pressure rubber pipe, thus wearing and tearing sebific duct surface.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
