Abstract
The utility discloses a double-screw lifting platform widely used among library, supermarket, building installation, interior and outdoor decoration and electric power installation and maintenance. The structure of the utility is as follows: bearing seat is fixed with screw bolt through bearing; one end of screw bolt is provided with transmission gear engaging with gear of output axle of power source; the screw bolt is mounted with threaded slide block; one end of support rod is fixed at threaded slide block, another end is connected with the platform. The utility can keep balance of platform, reduce cost, increase smoothness during lifting of platform and effective travel and is subject to positioning; lifting platform of same specification can increase lifting height.
Description
Technical field
The utility model relates to a kind of lifting table, relates in particular to a kind of twin screw lifting table, is widely used in places such as library, supermarket, building and installation, indoor and outdoor decoration, electric power installation and maintenance.
Background technology
In the prior art, applied lifting table mainly adopts single screw-rod structure in the mechanical device, promptly rotates the lifting that drives lifting table by driving single screw rod.Adopt the lifting table of said structure, owing to be single screw drive, mostly exist the jiggly problem of transmission, and in the working process, the power that screw rod bore is bigger, the balance of lifting table is hard to keep, and is difficult for the location.
In addition, also have a lot of devices to adopt hydraulic lift, hydraulic lift can overcome not steady, the difficult problem of locating of above-mentioned single screw rod lifting, but it must adopt devices such as oil cylinder, electromagnetic valve, and cost is higher, complex structure.
The utility model content
The utility model provides a kind of twin screw lifting table at above-mentioned problems of the prior art, has solved that the balance of lifting table is hard to keep in the prior art, is difficult for location, problem that cost is high, and flexible and convenient operation.
To achieve these goals, the technical solution of the utility model is as follows:
By bearing fixing screw rod is arranged on the bearing seat, an end of screw rod is provided with transmission gear, and transmission gear is meshed with the gear of propulsion source output axle head; Thread slider is installed on the screw rod, and an end of strut bar is fixed on the thread slider, and the other end of strut bar is connected with platform.
Be connected by bearing pin between described screw rod and the thread slider.
Described bearing seat is arranged on the support.
The utility model has the advantages of as follows:
1, owing to adopt the twin screw lifting,, locatees easily so can keep the flat-bed balance.
2, owing to devices such as oil cylinder, electromagnetic valve need not be set, so greatly reduce cost.
3, thread slider is moved to the centre by both sides simultaneously, and smoothness strengthens in the lifting platform process.
4, effective travel increases, and the lifting table of same specification can increase rise height.
5, can use manually in the occasion that does not have power supply.
Description of drawings
Below, in conjunction with the accompanying drawings, the utility model is elaborated.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. platform, 2. strut bar, 3. thread slider, 4. screw rod, 5. bearing pin, 6. bearing, 7. transmission gear, 8. bearing seat, 9. support.
The specific embodiment
Embodiment
As shown in Figure 1, bearing seat is installed on the support, by bearing fixing screw rod is arranged on the bearing seat, an end of screw rod is provided with transmission gear, and transmission gear is meshed with the gear of propulsion source output axle head; Thread slider 3 is installed on the screw rod 4, and an end of strut bar 2 is fixed on the thread slider 3 by bearing pin, and the other end of strut bar 2 is connected with platform.
Working process is as follows: the thread slider 3 that is installed on the screw rod 4 is moved to the centre by screw rod 4 both sides simultaneously, and the strut bar 2 that is fixed on the thread slider 3 by bearing pin 5 is closed gradually with moving of thread slider, drives platform 1 lifting of strut bar 2 other ends.Platform descended when screw rod rotated round about.Promptly rely on thread slider 3 on screw rod 4, to move, drive strut bar 2 foldings and come the device of implementation platform 1 lifting.The rotation that the occasion of power supply can the electrification drive screw is arranged, do not have the place of power supply can driven by shaking.Also this device can be fixed on self-propelled vehicle or the hand barrow as mobile lifting device.
