Abstract
The utility model relates to a spare tire hoisting device, which comprises a rope, a rope wheel, a crank and the like, and power is input into a speed reducer by the crank to drive a winding drum to achieve the purpose of ascending and descending a spare tire. The device solves the problems that the cooperation of multiple people is needed and time and labor are wasted in spare tire replacement. The spare tire is arranged in a higher position above the ground, and a special lifter is arranged, so the spare tire is convenient to lift and replace, and labor is saved. Only one person is needed for lifting and installing the spare tire, the labor intensity of personnel replacing the spare tire is greatly reduced, and the spare tire hoisting device has good economic benefits.
Description
Technical field
The utility model relates to the especially spare tyre hanging apparatus of oil field job that requires special skills automobile of special-use vehicle.
Background technology
Spare tyre is the motor tire of emergency.For general heavy-duty vehicle, spare tyre is lifted on rear overhang below or vehicle frame side, takes horizontal mode to place.Under the situation of space permission, this mode is a simple possible.But oil field job that requires special skills vehicle structure compactness often must be used to install miscellaneous part to realize the function of special operation in order to the space that spare tyre is installed originally.With the cementing concrete truck is example, and this part space requirement is installed centrifugal pump in order to pumping fluid, or lubrication box is installed and the tool box is used to store oil product and instrument.Certain position that this just forces spare tyre to be installed in to be higher than vehicle frame.Because the support installation site is higher, in case vehicle need be changed spare tyre in the open air, often needs 3 to 4 people it could be given rise to this eminence.If the appliance crew is less, can't finishes spare tyre at all and more change jobs.
Summary of the invention
The purpose of this utility model provides a kind of spare tyre hanging apparatus, solves the problem that spare tyre is changed to be needed multiple person cooperational, waste time and energy.By spare tyre being installed in liftoff higher position, and special elevator is set, make spare tyre lifting, change more convenient, laborsaving.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of spare tyre hanging apparatus is made up of rope, rope sheave, crank, is wound with rope on the rope sheave, and rope is a steel rope.In the below of column (3) retarder (2) is installed, the vertical installation that support (12) can be realized spare tyre is installed.Steel rope (9) acts on spare tyre by fixing column (3), rotary cantilever beam (7).The action of rotary cantilever beam (7) realizes by the slip between copper sheathing (5) and the rotating shaft (6).It is spacing to utilize location bearing shell (4) countershaft (6) to carry out, thereby the angular transposition of assurance cantilever beam (7) is in stated limit.Assembly pulley is installed.Assembly pulley is made up of two fixed pulleys (8), a movable pulley (10), a steel rope (9).Fixed pulley (8) is installed in the elbow and the end of cantilever beam (7) respectively, and movable pulley (10) overhangs the end of cantilever beam (7).Movable pulley and spare tyre are by rigging (11) bolt system, and rigging is made up of parts such as corrosion-resistant steel chain and spring latch hooks.The motion of reductor is delivered on the spare tyre by this a series of pulley mechanism and rigging just.
The beneficial effect that the utility model is had compared with the prior art is: system design is reasonable, simple in structure, save installing space, rapid operation is convenient, makes the lifting of spare tyre, installation exercise only need a people.Alleviated porter's labour intensity greatly.When vehicle ' in the Gobi desert, when the positive fetal hair of open-air road conditions such as desert, marsh is given birth to and damaged, only chaufeur one people just can realize the replacing of spare tyre fast.Retarder is taked the worm and gear structure, himself possesses the mechanical self-latching function.When manual driven power was ended, spare tyre can be suspended on original height and can not cause falling accident by by gravity, could realize the lifting of spare tyre when having only the crank action, had therefore improved the safety of operation.Cantilever beam can be by rotating mechanism around the rotation of column axis, in the appointment angular displacement range of motion amplitude between Fig. 2 and two end positions of Fig. 3, to guarantee that mechanism can not brush up against miscellaneous part and cause accidental damage.The design of rotating shaft guarantees that mechanism can not cause action not smooth because of corrosion.
Description of drawings
Fig. 1 is a front view of the present utility model, and Fig. 2 is the lateral plan of mode of operation of the present utility model, and Fig. 3 is the lateral plan of normal condition of the present utility model.
Among the figure: the 1-crank, the 2-retarder, the 3-column, 4-locatees bearing shell, 5-copper sheathing, 6-rotating shaft, 7-cantilever beam, 8-fixed pulley, 9-steel rope, 10-movable pulley, 11-rigging, 12-support.
The specific embodiment
The utility model will be further described by embodiment below in conjunction with Figure of description:
Referring to accompanying drawing, a kind of spare tyre hanging apparatus, support and elevator are installed on liftoff 1 to the 2 meter platform of special vehicle, and elevator is made up of column (3), rotating mechanism, cantilever beam (7), assembly pulley, retarder (2), crank (1), rigging (11).Wherein, rotating mechanism is made up of rotating shaft (6), location bearing shell (4), copper sheathing (5), and assembly pulley is made up of two fixed pulleys (8), a movable pulley (10), steel cable (9).
Described column (3) lower flange is by being bolted on the special vehicle platform.Location bearing shell (4), the copper sheathing (5) of described rotating mechanism are flush-mounted in column top.Rotating shaft (6) top and cantilever beam (7) are welded as a whole, and the middle part is plugged in the copper sheathing (5), and sports limiting is realized by location bearing shell (3) in the bottom.The axle center hollow of rotating shaft (6), column (3) and cantilever beam (7) all adopt tubular structure, are convenient to steel rope (9) and run through up and down.Cantilever beam (7) can rotate in specifying angular displacement range around column (3) axis by rotating mechanism.Two fixed pulleys (8) of assembly pulley are installed in the elbow and the end of cantilever beam (7) respectively, and the top of steel rope (9) is installed in cantilever beam (7) top, and terminal bolt ties up on the reel of retarder (2).During work, crank (1) drives the worm shaft rotation of retarder, by worm gear reducer rear drive reel.Steel rope (9) constantly twines to reel, drives movable pulley (10) and rigging (11) the lifting spare tyre that moves up.
During work, at first rotate cantilever beam (7) and make it stretch out vehicle width, will be placed on ground-surface spare tyre and movable pulley (10) bolt is with rigging (11), as shown in Figure 2.Clockwise rotate crank (1), make retarder (2) action of elevator, steel rope (9) constantly is wound on the reel of retarder (2), and movable pulley (10) drives spare tyre and rises.When lifting reaches specified altitude assignment, rotate cantilever beam and make it according to design corner displacement rotation, make spare tyre shift to support (12).Spare tyre is fixed on finishes lifting operation on the support, as shown in Figure 3.
