Accompanying drawing explanation
The accompanying drawing constituting the part of the present invention is used for providing a further understanding of the present invention, and the schematic description and description of the present invention is used for explaining the present invention, is not intended that inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 diagrammatically illustrates Anti-over-hoisting device provided by the invention and the stereochemical structure of building hoist section components；
Fig. 2 illustrates the partial enlargement structure in Fig. 1.
Detailed description of the invention
It should be noted that when not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Referring to Fig. 1 and Fig. 2, it is shown that the structure of the Anti-over-hoisting device for building hoist that the embodiment of the present invention provides, for purposes of illustration only, Fig. 1 also show the structure of the section components of building hoist.In conjunction with prior art it can be seen that building hoist mainly includes guide rail bracket and the lowering or hoisting gear that can vertically move along guide rail bracket.Wherein, guide rail bracket includes the support body (not shown in figure 1) formed by the standard knot that more piece is stacked, and the tooth bar 81 being fixedly mounted on support body and guide rail (not shown in figure 1), and the height of tooth bar 81 is essentially identical with the height of support body.Lowering or hoisting gear includes cage (not shown in figure 1) and drive division 9, cage can vertically move to transport workman along guide rail, drive division 9 includes drive section flame 91 and the motor 92 being arranged in drive section flame 91, gear 93, drive section flame 9 is arranged on the top of cage, with gear 93 is driven from motor 92 and engages with the tooth bar 81 of guide rail bracket, vertically move offer driving force for cage.
This Anti-over-hoisting device includes: mounting seat 1, briquetting 2 and travel switch 3.Mounting seat 1 is installed on the top of lowering or hoisting gear, it is preferable that mounting seat 1 is arranged on the top of driver framework 91 so that Anti-over-hoisting device is positioned at the top of whole lowering or hoisting gear, it is possible to reach the top of guide rail bracket at first.Mounting seat 1 has the slideway being obliquely installed, and briquetting 2 can have certain weight, and is slidably matched with slideway, and the slide downward of briquetting 2 is limited by guide rail bracket, makes briquetting 2 be on the proper height of slideway when building hoist normal operation.It is appreciated that in the process that Anti-over-hoisting device vertically moves with lowering or hoisting gear, briquetting 2 vertically moves along guide rail bracket.Briquetting 2 includes trigger unit 21, and travel switch 3 is arranged in the glide paths of trigger unit 21.Travel switch 3 may be mounted in mounting seat 3, can also be arranged on driver framework 91, it is appreciated that, when briquetting 2 glides along slideway, the trigger unit 21 of briquetting 2 is used for triggering travel switch 3 action, in conjunction with prior art it can be seen that travel switch 3 electrically connects with motor 92, it is possible to control startup and the stopping of motor 92.Preferably, travel switch 3 is Direct Action Type travel switch, advantageously reduces cost.
The Anti-over-hoisting device that the embodiment of the present invention provides runs up in process along with lowering or hoisting gear, briquetting 2 is close to guide rail bracket under self gravitation effect, when running to guide rail bracket top, the restriction of briquetting 2 first getaway frame, immediately along the slideway slide downward being obliquely installed under the effect of self gravitation, and trigger travel switch 3 by its trigger unit 21, thus the rapid power-off of motor 92 controlling lowering or hoisting gear drive division is out of service, realize braking, it is prevented that cage is rushed to summit.And briquetting 2 is under the effect of self gravitation and the frictional force of mounting seat 1 and under the constraint of slideway, even if impacting owing to cage jerk causes, it is not easy to upspring from travel switch, thus having reached the effect comparatively reliably avoiding cage to rush to summit.
In the process vertically moved along guide rail bracket along with lowering or hoisting gear at Anti-over-hoisting device, briquetting 2 can be slip cooperating relationship with guide rail bracket, the rolling matching relationship that can also go out as shown in this embodiment, referring to Fig. 2, briquetting 2 is provided with and rolls, with guide rail bracket, the roller 4 coordinated, and is so conducive to alleviating the abrasion of briquetting 2 and guide rail bracket.Preferably, the tooth bar 81 of roller 4 and guide rail bracket rolls and coordinates, and tooth bar 81 can provide relatively smooth rolling plane to roller 4 so that the slip of briquetting 2 opposite rail frame is more smoothly reliably, reduces abrasion further.
Preferably, present embodiment illustrates a kind of preferred implementation of mounting seat 1 sliding way, referring to Fig. 2, this mounting seat 1 includes swash plate 11, and swash plate 11 offers elongated hole 110, and elongated hole 110 forms slideway, and briquetting 2 and this elongated hole 110 are slidably matched.Certainly in other embodiments, the slideway in mounting seat 1 can also be such as other suitable structures such as female groove structures, in this not reinflated description.
Preferably, also show a kind of preferred implementation of briquetting 2 in the present embodiment, the slideway formed with above-mentioned elongated hole 110 is slidably matched.Specifically, briquetting 2 includes the body 22 and the trigger unit 21 that removably connect, and body 22 and trigger unit 21 are such as connected by connecting bolt.Body 22 is positioned at the upside of swash plate 11, it is possible to possessing heavier weight, roller 4 is arranged on body 22.Trigger unit 21 is positioned at the downside of swash plate 11, it will be understood that the connecting portion between body 22 and trigger unit 21 and elongated hole 110 are slidably matched.Travel switch 3 is preferably mounted on the swash plate 11 of mounting seat 1 so that overall simple and compact for structure of Anti-over-hoisting device, it is easy to assemble with building hoist, and simple in construction, cost are low.Additionally, for ease of being slidably matched of briquetting 2 and elongated hole 110, preferably, it is possible to the boss being slidably matched with elongated hole 110 is set on body or trigger unit 21, or is directly slidably matched connecting the body 22 connecting bolt with trigger unit 21 with elongated hole 110.
Preferably, as can be seen from Figure, in the present embodiment, mounting seat 1 also includes the riser 12 being connected with swash plate 11, and riser 12 is removably mounted on the top of the drive section flame 91 of lowering or hoisting gear by bolt or screw, is conducive to alleviating the weight of mounting seat 1.It is appreciated that travel switch may be mounted on riser 12 when elongated hole 110 and the close together of riser 12.Certainly, in actual applications, the structure of mounting seat 1 is also a variety of, does not repeat them here.
The embodiment of the present invention additionally provides a kind of building hoist, and this building hoist is provided with above-mentioned Anti-over-hoisting device.The Anti-over-hoisting device provided due to the embodiment of the present invention can reach above-mentioned technique effect, and the building hoist being provided with this Anti-over-hoisting device also should possess corresponding technique effect, does not repeat them here.
These are only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
