Description
The cross reference of related application
With reference to by contriver Anthony Shakal and John Holman the name of filing an application on the same day with the application be called the number one non-provisional application of " HOSE REEL FRAME AND GUDIE ARM " and by contriver Anthony Shakal and Scott Hill in the number one non-provisional application that is called " HOSE REEL LATCH " of filing an application on the same day with the application.
Technical field
The present invention relates in general to hose reel, and relates more specifically to have the hose reel spool that flexible pipe is remained on the sidepiece on the spool.
Background technology
Hose reel is generally used for putting in order the current-carrying flexible pipe.The flexible pipe of reeling occupies less space, and not can with the ambient circumvolution.The industrial hose reel utilizes torsion spring or counterweight biased usually, under the situation that does not have stretching force to act on to be connected on the flexible pipe of spool, automatically to roll flexible pipe.
Hose reel generally includes three major parts: spool, framework and guide arm.The hose reel spool generally includes the hub with cylindrical wall and axial opposing sidewalls.Sidewall and cylindrical wall limit annular retaining zone together, and the flexible pipe of coiling is stored in this annular retaining zone.The anchored end of flexible pipe usually through or be connected to the flexible pipe installation portion on the cylindrical wall.This flexible pipe installation portion tilts usually, with flexible pipe around reel disc around the time prevent that flexible pipe is overflexing.In addition, a plurality of hose reels also comprise the framework or the support of support and grappling spool.This framework can be connected to the one or both sides of spool.The flexible pipe framework must be able to support the total weight of the spool that is mounted with flexible pipe, and any strain that is associated with coiling and unwinding hoses.In addition, some hose reels comprise the winding of guide arm with guiding hose, guarantee that by this flexible pipe correctly is wound on the spool.Similar with framework, guide arm can be connected to the one or both sides of hose reel.Most of guide arms are rotatably connected, so that allow flexible pipe to be twined and unwinding with the angle of certain limit.
In the past, some hose reels comprise the ratchet latch assembly, to prevent that flexible pipe from returning in use or to twine again.These latch assemblies are usually included in the ratchet on any in hose reel framework or the guide arm and are fixed to the dentation pawl member of a side of spool.Usually because cost that increases and required manufacturing time, previous hose reel comprises on any one that is used for framework or guide arm but is not the installation portion that is used for the ratchet on framework and the guide arm.The engaged pawl pawl member prevents that with the rotation of restriction spool spool from twining.Through this latch assembly, the flexible pipe of breech lock through at first make flexible pipe slightly unwinding so that pawl member is separated with ratchet by being return.This can prove if engaged pawl flexible pipe unwinding fully simultaneously is difficult.In this case, under the situation of not dismantling hose reel, can not untie and twine again flexible pipe.Can guarantee on the guide arm that this situation can not occur through pawl member being manufactured on spool being installed in the radially opposite side flexible pipe installation portion and with ratchet.When the complete unwinding of flexible pipe, the flexible pipe installation portion will with the guide arm radial.Therefore, when flexible pipe was fully stretched, the ratchet that is installed on the guide arm engaged the pawl member relative with the flexible pipe installation portion never.This solution is unavailable when hose reel does not comprise guide arm.Guide arm is omitted in the application with cost saving, weight or space therein, and latching portion must be installed in other place or not have latching portion.
Preferably, hose reel is firm, compact and assembled easily.In the past, the hose reel framework is configured to have axial outward extending support lugn sometimes, and the hose reel spool is configured to have axially outward-dipping plate-like sidewall sometimes.This structure provides extra intensity, but heavier than smooth spool, therefore need have the broad coverage zone than big frame.The convenience of assembling all is important with making afterwards during manufacture; Particularly, it is desirable to hose reel and be easy to be suitable for different working condition and application.
Summary of the invention
The present invention relates to a kind of hose reel spool with two recesses and plate-like sidewall of supporting cylindrical wall.This side-wall shaft is to sloping inwardly, thereby when sidewall extends radially outwardly, assembles toward each other.

The specific embodiment
I. summarize
Fig. 1 a and 1b have described hose reel assembly 10; Hose reel assembly 10 comprises that spool 12 (having sidewall 108a and 108b), framework 14 (have frame base 26 and frame side 28a and 28b; Frame side 28a and 28b (having flange 30 and column bolt 29), guide arm 16 (have L shaped 32 and I shape part 34, each has hole or recess 31), flexible pipe 18, hole 20, anchor portion 22, installation component 23, pawl member 24 and ratchet 25 (diplopia that draws in guide arm 16 back).Fig. 1 a and 1b have also shown coiling direction and expansion direction UW.Spool 12 rotations are with the flexible pipe 18 that twines and unwinding centers on the central cylindrical surface and between the sidepiece of spool 12, reels.
Spool 12 comprises that axial hub 104 is (invisible in Fig. 1 a or 1b; Referring to Fig. 2) and the first side wall 108 and the second sidewall 108b that radially extend.As described, spool 12 is continued to use in coiling direction W that twines flexible pipe 18 and the expansion direction UW that is used for unwinding flexible pipe 18 and is rotated.In other embodiments, spool 12 can be made to twine and unwinding flexible pipe 18 along opposite direction.Framework 14 supporting reels 12 and guide arm 16.Guide arm 16 extends with maintenance flexible pipe 18 as shown in the figure from framework 14.Spool 12 is rotatably connected to framework 14 through installation component 23, and in certain embodiments, this installation component is to extend through the part 32 of spool 12, frame side 28a and 28b and guide arm 16 and 34 center-wheel arbor or pin.In one embodiment, spool 12 is biased (for example passing through torsion spring) with there not being the situation lower edge coiling direction W rotation of opposing force, twines flexible pipe 18 by this.The sidepiece 108a and the 108b of spool 12 axially slope inwardly when it extends radially outwardly, and sidepiece 108a tilts towards sidepiece 108b, and vice versa.This incline structure strengthen spool 12 and avoid sidewall 108a and 108b and flange 30 (being described below) between contact.
Pawl member 24 is fixed to spool 12, and is connected with ratchet 25 on the guide arm 16, returns inadequately to prevent flexible pipe 18.As shown in the figure, pawl member 24 is only across the part radial strut of spool 12, therefore only aims at the ratchet 25 of the part of each rotation that is used for spool 12.It is punctual to be rotated into 25 pairs on ratchet along the UW direction in pawl member 24, and ratchet 25 blocks pawl member 24, thereby applies the contrarotation power of spool 12 along the rotation of W direction that prevents.It is punctual perhaps to be rotated into 25 pairs on ratchet along the W direction at pawl member 24 and ratchet 25 mis-aligneds, and ratchet 25 can not be stuck on the pawl member 24, and can not prevent that spool 12 is along any one direction rotation.Though ratchet 25 is shown on the guide arm 16 that is installed among Fig. 1 a, ratchet 25 can be installed on the framework 14 alternatively.
Fig. 2 is the front view of spool 12 (having spool half part 102a and 102b); Spool comprises axial hub 104 (have outer cylindrical wall 106, this outer cylindrical wall 106 has flexible pipe installation portion 112), sidewall 108a (having the outer annular lip shape 118a of portion) and sidewall 108b (having outer annular lip shape 118b of portion and annular ridge 114).Outer cylindrical wall 106 limits annular hose retaining zone 110 together with sidewall 108a and 108b.
As stated, spool 12 is made up of with sidewall 108a and 108b axial hub 104.Axially hub 104 comprises that inner end wall 120 is (invisible in Fig. 2; Referring to Fig. 3) and outer cylindrical wall 106.Outer cylindrical wall 106 is outermost radial outside cylindrical parts of axial hub 104. Sidewall 108a and 108b are the annular flange flange that the edge from outer cylindrical wall 106 extends radially outwardly.Outer cylindrical wall 106 limits flexible pipe retaining zone 110 and annular space with sidewall 108a and 108b, and flexible pipe 18 is wound into and is used in this annular space storing.In one embodiment, spool 12 is formed two halves.The first half spool 102a comprise the first side wall 108a and Outer cylindrical wall part 106a.The second half spool 102b comprise second sidewall 108 and Outer cylindrical wall part 106b.Spool 12 is through with the first half spool 102a and the second half spool 102b welding or be threaded and form together.
Be wound onto 12 last times of spool in the hole 20 (referring to Fig. 1 a and 1b) of flexible pipe through guide arm 16; Flexible pipe piles Pyramid naturally; 106 places seldom have the width more than four flexible pipe width in outer cylindrical wall, and owing to flexible pipe radially outward piles up, so narrower basically.Therefore outer cylindrical wall 106 is designed to only have a little more than the width of four flexible pipe width, and this is because extra width will increase the volume of hose reel assembly 10, and does not have benefit.
Fig. 3 is the lateral plan of spool 12, has shown sidewall 108b, annular ridge 114, mounting hole 116, the outer annular lip shape 118b of portion, the inner end wall 120 with installation site 122 and pawl member 24.As previously mentioned, axially hub 104 comprises inner end wall 120 and outer cylindrical wall 106.Inner end wall 120 is smooth radial surfaces of radially inner in-to-in across spool 12 (referring to Fig. 2) of cylindrical wall 106.Inner end wall 120 also comprises installation site 122.Installation component 25 is fastened to installation site 122 so that spool 12 is supported on the framework 14.In one embodiment, installation component 24 is axle or pin, and installation site 122 is the passages that pass inner end wall 120, and the installation component assembling is through inner end wall 120.Installation site 122 below by explanation in further detail.
The radially outer of sidewall 108a and 108b is axially outwards turnover in outer annular lip shape 118a of portion that strengthens spool 12 and 118b.The second sidewall 108b ends at the second outer annular lip shape 118b of portion, and the second outer annular lip shape 118b of portion is axially away from flexible pipe retaining zone and the first side wall 108a turnover.Similarly, the first side wall 108a is (invisible in Fig. 3; Referring to Fig. 2 and 4) end in the first outer annular lip shape portion 118 and finish, the first outer annular lip shape 118a of portion is axially away from flexible pipe retaining zone 110 and second sidewall 108b turnover.Because sidewall 108a and 108b axially slope inwardly when sidewall 108a and 108b extend radially outwardly, so outer annular lip shape portion 118 can not increase the overall width of spool 12.As stated, pawl member 24 connect through screw or be riveted to sidewall 108b with ratchet 25 mutual actions.Fig. 3 also shows hatching 4-4, and this hatching 4-4 passes the axis of spool 12.
Fig. 4 is the exploded cross section views along the spool 12 of the hatching 4-4 intercepting of Fig. 3.Fig. 4 shows spool 12, and spool 12 comprises outer cylindrical wall 106, sidewall 108a and 108b, the outer annular lip shape 118a of portion and 118b, inner end wall part 120a and 120b, installation site 122, the collar 124 and hole 126.For clarity sake, Fig. 4 has shown spool half part 102a and the 102b that decomposes.When spool 12 was assembled, spool half part 102a and 102b linked together, as previously mentioned.Installation component 25 through installation site 122 so that spool 12 is anchored to framework 14.
Among the embodiment that spool 12 is formed by two and half parts therein, inner end wall 120 can be divided into two adjacent parts: the first inner end wall part 120a (being the part of the first half spool 102a) and the second inner end wall part 120b (being the part of the second half spool 102b).These parts by bolt or weld together so that spool half part 102a is connected to spool half part 102b.In one embodiment, the first inner end wall part 120a comprises hole 126, and the second inner end wall part 120b comprises the collar 124.Hole 126 is centre holes among the axial end wall part 120a in second, and enough greatly to hold the collar 124.The collar 124 is that the center shaft of axle journal that passes through hole 126 and be formed for installation component 25 of axial end wall part 120b in second is to extendible portion.In another embodiment, the position of the collar 124 is opposite with hole 126: the collar 124 is positioned on the first inner end wall part 120a, and hole 126 is arranged in the second inner end wall part 120b.Axle bush or bearing are inserted in the collar 124 with at spool 12 time rotational supporting reels 12.
As stated, because sidewall 108 extends radially outwardly, sidewall 108 axially slopes inwardly and is used to gain in strength.This slope inwardly be designed to pile up profile and be complementary around the above-mentioned natural pyramid of interior annular ring 106 and flexible pipe 18, therefore can not hinder winding.The outermost radial outside edge termination of the first side wall 108a is in the first outer annular lip shape 118a of portion, and the outermost radial outside edge termination of the second sidewall 108b is in second 118b of outer ring spine.118a of outer ring spine and 118b further strengthen spool 12.
Fig. 4 also shows region R, and region R is surrounded a part and the second sidewall 108b of outer cylindrical wall 106.
