Abstract
The utility model relates to a pneumatic spare wheel rack which is composed of a cylinder (1), a piston (2), a piston rod (3), a pulley (5), a steel rope (4), a carrier rack (7) and a rack (6). The cylinder (1) is fixedly connected with the rack (6), and four pulleys (5) are provided. Wherein, one pulley (5) is arranged on the piston rod (3), and the other three pulleys (5) are arranged on the rack (6). One end of the steel rope (4) is connected on the piston rod (3). After the steel rope (4) continuously passes through the four pulleys (5), the steel rope (4) is connected with the carrier rack (7) which is placed with a spare wheel (8). An air inlet pipe (10) and an air outlet pipe (13) are connected on the cylinder (1), and the air outlet pipe (13) is provided with an air escape valve (11). The utility model not only is convenient and labor-saving in loading and unloading the spare wheel, but also can increase the elevating height of the carrier rack, making the carrier rack be suitable for an automobile the chassis of which is higher off the ground surface and enlarging the using range of the pneumatic spare wheel rack.
Description
Technical field
The utility model relates to a kind of Das Reserverad moulding bed of automobile, specifically, relates to a kind of pneumatic type spare tyre holder.
Background technology
At present, autotruck spare tyre mostly very important person loads and unloads spare tyre by hand, and labour intensity is very big, and very easily has an accident when loading and unloading.Also have a kind of shaking spare tyre lifter in the prior art, after its shortcoming was to use one or two years, rising or falling speed was very slow, and very painstaking, and the phenomenon that latch can unload any more spare tyre and slip teeth drops spare tyre very easily takes place.Chinese patent CN2425836Y discloses a kind of vapour-pressure type spare tyre holder, prior art is improved, mainly contain compositions such as cylinder, piston rod, pulley, steel rope, support and carriage, it utilizes air pressure promotion piston rod to advance, make steel rope with the carriage pull-up, reached loading and unloading spare tyre convenience, labour-saving purpose.But also there is following deficiency in this structure, because pulley has only three, when piston rod advances, the height that steel rope rises is the twice of piston rod miles of relative movement, steel rope drives the insufficient height that carriage can lifting, be not suitable for the chassis overhead than higher automobile, limited its range of use.And when steel rope drove the insufficient height of carriage lifting, spare tyre just fell less than ground when descending, and the loading and unloading spare tyre is still inconvenient.
Summary of the invention
The purpose of this utility model provides that a kind of not only to load and unload spare tyre convenient, laborsaving, and can increase the pneumatic type spare tyre holder of carriage adjustable height.
The technical scheme that realizes above-mentioned purpose is: a kind of pneumatic type spare tyre holder, form by cylinder, piston, piston rod, pulley, steel rope, carriage and support, cylinder is captiveed joint with support, pulley has four, wherein a pulley is installed on the piston rod, other three pulleys are rack-mount, one end of steel rope is connected on the piston rod, and steel rope is connected with the carriage of placing spare tyre after continuing to pass through four pulleys, be connected with air inlet pipe and freeing pipe on the cylinder, freeing pipe is provided with aie escape valve.
After adopting technique scheme, because pulley has four, wherein a pulley is installed on the piston rod, other three pulleys are rack-mount, one end of steel rope is connected on the piston rod, and steel rope is connected with the carriage of placing spare tyre after continuing to pass through four pulleys, when advancing under the effect of piston rod at air pressure, the length that steel rope rises is three times of piston rod miles of relative movement, and steel rope drives the carriage rising, thereby can increase the adjustable height of carriage, make spare tyre holder also can the chassis overhead than higher automobile, enlarged the range of use of spare tyre holder, and guaranteed that carriage can fall earthward, and is convenient to the loading and unloading of spare tyre when descending.The novel air pressure that leans on of this use makes the carriage lifting as power by steel rope, and is easy to loading and unloading, laborsaving, also avoided latch, the slip teeth phenomenon of shaking spare tyre lifter simultaneously.
Description of drawings
Fig. 1 is a main TV structure scheme drawing of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
As shown in Figure 1, 2, a kind of pneumatic type spare tyre holder, form by cylinder 1, piston 2, piston rod 3, pulley 5, steel rope 4, carriage 7 and support 6, cylinder 1 is captiveed joint with support 6, pulley 5 has four, wherein a pulley 5 is installed on the piston rod 3, other three pulleys 5 are installed on the support 6, one end of steel rope 4 is connected on the piston rod 3, and steel rope 4 continues to pass through four pulleys, 5 backs and is connected with the carriage 7 of placing spare tyre 8, be connected with air inlet pipe 10 and freeing pipe 13 on the cylinder 1, freeing pipe 13 is provided with aie escape valve 11.During installation, support 6 is fixed on the adapter plate 9 by screw bolt and nut, again adapter plate 9 is fixed on the crossbeam of automobile.Tracheae on the automobile is received on the air inlet pipe 10 of cylinder 1.
As shown in Figure 2, be provided with adaptor union 12 in the support 6, two of adaptor union 12 is threaded with freeing pipe 13 respectively.Adopt this structure to be convenient to the vapour-pressure type spare tyre holder is installed to the automobile bottom, the length that can prolong freeing pipe 13 simultaneously, also just can make the aie escape valve 11 on the freeing pipe 13 be positioned at the position that automobile side is convenient to operate, be convenient to operate aie escape valve 11, make things convenient for venting widely.And the vapour-pressure type spare tyre holder air inlet in the past and the shared tracheae of giving vent to anger, and change-over valve has been installed on tracheae, by the change-over valve venting, this change-over valve also is positioned at the automobile bottom near support, thereby venting is extremely inconvenient.This uses later-model structure to overcome above-mentioned shortcoming.
Principle of work of the present utility model is as follows: in the time of need laying spare tyre toward the bottom of automobile, earlier spare tyre 8 is fixedly mounted on carriage 7 above, source of the gas with automobile is inflated to cylinder 1, piston rod 3 advances under the effect of air pressure, piston rod 3 drives steel rope 4 and advances, and steel rope 4 drives connected carriage 7 and rises, when rising near adapter plate 9, stop inflation, promptly finish laying of spare tyre.Broken as wheel, when needing to change spare tyre, the spare tyre of automobile bottom to be unloaded earlier, at this moment, as long as will open aie escape valve 11 on the freeing pipe 13, make cylinder 1 venting, carriage 7 will fall under the effect of self gravitation and spare tyre 8 gravity, drives piston rod by steel rope simultaneously and retreats into initial position, and carriage falls earthward, just can easily spare tyre 8 be taken off, replace bad tire then and install on the axletree.
