Abstract
The utility model discloses an adjustable wheel type screw support device and relates to the technical field of water conservancy engineering. The adjustable wheel type screw support device comprises a base plate, two vertical plates and two support wheels. The vertical plates which are in left-right symmetry are vertically fixedly connected to the upper surface of the base plate. The support wheels which are in up-down parallelism are disposed at the tops of the two vertical plates. The support wheels are detachably connected with the vertical plates through double nut bolts. The adjustable wheel type screw support device has the advantages that rolling wheel type support is used, friction force of the support wheels to a screw is small, corresponding abrasion is small, a self-lubricating shaft sleeve is added to each support wheel, regular lubricating maintenance is avoided, time and labor are saved, the service life is prolonged, the friction coefficient of the adjustable wheel type screw support device is evidently lowered as compared with the friction coefficient of a steel pipe or cement support device, great convenience is brought to mounting by mounting holes, only bolt fixing is needed, convenient mounting and demounting are achieved, and adjustability is increased.
Description
Technical field
The utility model relates to hydraulic engineering technical field, relates in particular to a kind of adjustable wheeled screw mandrel support device.
Background technique
At present, in hydraulic engineering, the most of cement that adopts of the support device of oblique pull gate screw mandrel supports or steel pipe support, during open-close sluice gate, screw mandrel supports or moves back and forth above steel pipe support at cement, owing to producing larger frictional force in the process in motion, larger frictional force causes the wearing and tearing of screw mandrel, has had a strong impact on the working life of screw mandrel.Cement supports or steel pipe support exists certain error when construction, once after fixed installation, dislocation is mobile very difficult, and adjustment and installation gets up also inconvenient, there is above problem in existing these screw lead supporting devices, we provide a kind of adjustable wheeled screw mandrel support device for this reason.
Model utility content
Technical problem to be solved in the utility model be to provide a kind of simple in structure, easy for installation, tunable performance is good, the adjustable wheeled screw mandrel support device of long service life.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of adjustable wheeled screw mandrel support device, comprise base plate, riser and supporting wheel, described riser is provided with two, symmetrically vertically be fixedly connected on described plate upper surface, described supporting wheel is provided with two, upper and lower parallel be arranged between two risers top, described supporting wheel removably connects by double nut bolt and symmetrical riser.
Preferably, described supporting wheel middle part is provided with race, the rotation that moves back and forth the described supporting wheel of drive of described screw mandrel, and described supporting wheel inside is provided with self lubrication bearing.
Preferably, described base plate is at least provided with two mounting holes.
The beneficial effect that adopts technique scheme to produce is: the utility model adopts the wheeled support of rolling type, supporting wheel is less to the frictional force of screw mandrel, corresponding wearing and tearing are also smaller, on supporting wheel, installed self lubrication bearing additional, avoided the work of intermittent oiling maintenance, time saving and energy saving, and increased working life, the relative steel pipe of roller type support device friction factor or cement support device that self lubrication bearing is installed in employing additional obviously reduce, by mounting hole, very model utility is brought great convenience at installation, only need bolt fixing, easy accessibility, increased adjustability.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure sectional view;
Wherein, 1 base plate, 2 risers, 3 supporting wheels, 4 selflubricating sleeves, 5 double nut bolts, 6 mounting holes.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model is a kind of adjustable wheeled screw mandrel support device, comprise base plate 1, riser 2 and supporting wheel 3, described riser 2 is provided with two, symmetrically vertically be fixedly connected on described base plate 1 upper surface, described supporting wheel 3 is provided with two, upper and lower parallel be arranged between two risers top, described supporting wheel 3 removably connects by double nut bolt 5 and symmetrical riser 2; Described supporting wheel 3 middle parts are provided with race, and described in it, tongue can also be arranged in supporting wheel 3 middle parts, the rotation that moves back and forth the described supporting wheel 3 of drive of described screw mandrel, and described supporting wheel 3 inside are provided with self lubrication bearing 4; Described base plate 1 is at least provided with two mounting holes 6.
The utility model adopts the wheeled support of rolling type, supporting wheel is less to the frictional force of screw mandrel, corresponding wearing and tearing are also smaller, on supporting wheel, installed self lubrication bearing additional, avoided the work of intermittent oiling maintenance, time saving and energy saving, and increased working life, the relative steel pipe of roller type support device friction factor or cement support device that self lubrication bearing is installed in employing additional obviously reduce, by mounting hole, very model utility is brought great convenience at installation, only need bolt fixing, easy accessibility, has increased adjustability.
The utility model supports with steel pipe socket and supports and compare the wearing and tearing that reduced screw mandrel with cement, extended the working life of screw mandrel, adopted the wheeled support of rolling type, to almost not wearing and tearing of screw mandrel, on two wheels of wheeled support, self lubrication bearing is housed, has saved the work of intermittent oiling maintenance.Reduced to a certain extent the hoisting capacity of gate; Friction factor while adopting steel pipe socket to support is 0.5 ~ 0.6, and the roller type support friction factor that self lubrication bearing is equipped with in employing is 0.12 ~ 0.14, has reduced to a certain extent thus the hoisting capacity of gate; Owing to there is certain error in civil engineering process, the adjustability of this device brings great convenience in installation; This device is easy for installation, only needs four bolts fixing, in reinforcement engineering, can adopt chemical anchor bolts, can pre-buried first phase embedded part.
