As an improvement, being connected with the balanced weight for mitigating motor load on the top of the slide plate.
Compared with prior art, the utility model has the following beneficial effects: the utility model pulls lifting using a pair of of chain Platform is gone up and down in the guide rail made of channel steel, changes traffic direction by motor commutation, chain is sturdy and durable, the motor of strap brake Guarantee that platform out of control will not glide under halted state.In addition, slide plate, which is connected with balanced weight, can mitigate workbench loading rising When motor load, workbench decline is also driven by a motor, it is ensured that decline process velocity-stabilization, and have safety, hard Gu the features such as durable, cheap, maintenance is simple.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is structural schematic diagram of the utility model about driving device.
Fig. 3 is second of embodiment of the utility model.
In figure:
Bottom plate 1, hoistable platform 3, driving device 4, the first chain 5, the second chain 6, balanced weight 7, pulley 8, subtracts guide rail 2 Fast case 9, workbench 30, slide plate 31, motor 41, transmission shaft 42, speed adjusting gear 43, upper sprocket wheel 44, top 310, minor sprocket 430, Big sprocket wheel 431, lower sprocket 432.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As depicted in figs. 1 and 2, a kind of chain-type elevator, including bottom plate 1, guide rail 2 and the liter being vertically moved up or down along guide rail 2 Platform 3 drops, and the bottom plate 1 is equipped with the driving device 4 for driving hoistable platform 3 to go up and down, and the driving device 4 includes motor 41, transmission shaft 42, speed adjusting gear 43 and the upper sprocket wheel 44 being connected with motor 41, in the present embodiment one, the speed adjusting gear 43 Including minor sprocket 430, big sprocket wheel 431 and lower sprocket 432, the minor sprocket 430, big sprocket wheel 431 are successively coaxially set from top to bottom It sets on lower sprocket 432, so that the shaping modes of two stage speed change are formed, it is vertical flat locating for the central axis of the lower sprocket 432 Vertical plane locating for the central axis of face and upper sprocket wheel 44 is on same vertical plane, the minor sprocket 430 and big sprocket wheel 431 Horizontal plane locating for horizontal plane locating for central axis and transmission shaft 42 guarantees the smooth rotation of chain in same level.Institute It states the first chain 5 and the engagement turn on minor sprocket 430 or big sprocket wheel 431 can be switched by the control of derailleur (not shown) It is dynamic, specifically, the derailleur is the product (derailleur as being used for bicycle) for utilizing market on sale, made according to actual The first chain 5 and 430 engagement rotation of minor sprocket are adjusted by derailleur with environment, or the first chain is adjusted by derailleur Item 5 and 431 engagement rotation of big sprocket wheel so far realize that lower sprocket 432 has different revolving speeds, and then effectively control hoistable platform 3 The speed of lifting.In addition, the upper sprocket wheel 44 is connect by the second chain 6 with lower sprocket 432, to realize driven, that is, pass through Lower sprocket 432 is driven, the upper sprocket wheel 44 also and then rotates.
As the further improvement of the present embodiment one, in 1 upside of bottom plate, purpose exists for the exposed setting of speed adjusting gear 43 In maintenance and observation, although explanation, to those skilled in the art, the speed adjusting gear 43 is not limited only to minor sprocket 430 and 431 two stage speed change of big sprocket wheel adjusting, can also be three-level or level Four or even the other speed change of more stages.
It is the engagement rotation such as adjustable first chain 5 and minor sprocket 430 or big sprocket wheel 431 for derailleur is described in detail, As shown in Fig. 2, when operator needs steady and slowly hoistable platform 3 speed, user can be by stirring derailleur, by the One chain 5 is engaged with big sprocket wheel 431, by the output of 42 fixed rotating speed of transmission shaft, rotates big sprocket wheel 431 slowly, and then make Hoistable platform 3 is slowly effectively risen by the cooperation of the second chain 6 and upper sprocket wheel 44 or steady decline.Similarly, work as use Person is to go up and down hoistable platform 3 quick smoothly, and user is by stirring derailleur, by the first chain 5 and minor sprocket 430 Engagement, by the output of 42 fixed rotating speed of transmission shaft, makes 430 quick rotation of minor sprocket, and then hoistable platform 3 is made to pass through the second chain The cooperation of item 6 and upper sprocket wheel 44 and quick smoothly rise or fall.
As shown in Figure 1, the hoistable platform 3 includes workbench 30 and slide plate 31, the slide plate 31 is mounted on the second chain 6 It above and in guide rail 2 slides up and down, wherein workbench 30 is fixedly connected with slide plate 31, to realize the lifting of workbench 30.As It improves, the balanced weight 7 for mitigating 41 load of motor is connected on the top 310 of slide plate 31, the balanced weight 7 passes through two cunnings Wheel 8 is connected with the top 310 of slide plate 31, convenient for slidably reciprocating for balanced weight 7;Specifically, the balanced weight 7 can mitigate liter The load of motor 41 when 3 loading of platform rises drops, the decline of hoistable platform 3 is also driven by motor 41, it is ensured that decline process speed Degree is stablized.
As shown in figure 3, being second embodiment of the utility model, substantially similar to embodiment one, the embodiment two The places different from embodiment one are, add a reduction gearbox 9, and transmission shaft 42 is arranged on reduction gearbox 9, motor 41 and deceleration The other end of case 9 is connected.When operating, the rotation of motor 41 drives reduction gearbox 9 to work, and reduction gearbox 9 so that drive transmission shaft 42 again Rotation, the purpose being arranged in this way be using reduction gearbox 9 self-locking function guarantee hoistable platform 3 under halted state will not it is out of control under It is sliding, improve the safety of the utility model.
In conclusion the utility model structure is simple, low cost, maintenance and replacement are simple, have safe, sturdy and durable etc. Feature can bring economic benefit for enterprise.
