Abstract
The utility model discloses a vehicle-mounted access ladder device comprising an access ladder, a driving lever and a driving shaft, wherein the driving shaft is fixed on a vehicle frame by a fixed seat; the driving shaft is matched with the fixed seat in a sliding way; the driving lever is fixedly sheathed on the driving shaft by a shaft sleeve arranged on the driving lever; the access ladder is sheathed on the driving shaft by the shaft sleeve; and the driving lever is externally connected with a power source. The driving lever is driven by the external power source; the turnover of the access ladder is realized as follows: the driving lever drives the driving shaft and the driving shaft drives the access ladder; other parts are not connected with the access ladder, and the access ladder can move freely along the driving shaft in the radial direction, thus meeting the vertical movement of the mechanical vehicles with different wheel distances or the merchandise with different widths; therefore, the access ladder has wide application scope; and the driving lever can realize automatic control by the external power source, therefore, the labor intensity of the worker is greatly lightened, the working efficiency is improved, and the safety of people is ensured.
Description
Technical field
The utility model relates to a kind of vehicle-mounted climbing ladder apparatus that is used for the transport vehicle handling goods.
Background technology
Construction machinery and equipment transportation special-use vehicle because equipment volume, weight are bigger, all needs can finish by means of cat ladder when the various engineering mechanical device of loading and unloading.Known cat ladder structure has spring assist cat ladder and multiple stage cat ladder.The rotation of these two kinds of cat ladders all is to realize requirement on machining accuracy height, installation and maintenance complexity by bearing pin; Driving then is that external force direct drive cat ladder is realized, has limited the side travel of cat ladder.Must be auxiliary when the spring assist cat ladder uses by manpower, labor strength is big, poor stability, and lateral dimension fixes, and can only adapt to the loading and unloading of the motor vehicles and machines of certain limit wheelspan; Multiple stage cat ladder structure is comparatively complicated, and lateral dimension is also fixed simultaneously, can not satisfy the loading and unloading of wheelspan motor vehicles and machines on a large scale equally.
Summary of the invention
In order to overcome the above-mentioned defective that the known technology field exists, the purpose of this utility model is, a kind of novel on-vehicle climbing ladder apparatus is provided, it can solve in the prior art because of structural limitations, cat ladder can not side travel, can not adapt to the loading and unloading of wheelspan vehicle on a large scale, need be in the cat ladder switching process by defectives such as manpower, requirement on machining accuracy height and installation and maintenance complexity.
The vehicle-mounted climbing ladder apparatus that the utility model provides, it comprises cat ladder, activation lever, axle drive shaft, described axle drive shaft is fixedly installed on the vehicle frame by permanent seat, bearing fit between axle drive shaft and the permanent seat, activation lever is fixed on the axle drive shaft by self axle sleeve suit, cat ladder is sleeved on the axle drive shaft by axle sleeve, the external propulsion source of activation lever.
Described axle drive shaft comprises cylindrical gooseneck part, axle base portion, and cylindrical gooseneck part matches with permanent seat, and bearing fit between the permanent seat, and the axle base portion matches with activation lever axle sleeve and cat ladder axle sleeve.The cross sectional shape of the axle base portion of described axle drive shaft, be circular trough of belt or circular band projection or oblong or rectangle or polygon, the axle sleeve cross section of described cat ladder is identical with the axle main body section, radially slide cooperation along axle drive shaft between the two, can limit the cat ladder axle sleeve can not rotate along the axle drive shaft axial line, but can move radially along axle drive shaft.
The vehicle-mounted climbing ladder apparatus that the utility model provides, its beneficial effect is: 1. activation lever is by external drive power source, the upset of cat ladder drives axle drive shaft by activation lever, axle drive shaft drives cat ladder and realizes, owing to there are not other parts to be connected with cat ladder, cat ladder can radially move freely along axle drive shaft, can satisfy the motor vehicles and machines of different wheelspans or the goods of different in width and move up and down applied range; 2. activation lever can realize automatic guidance by the external force source, alleviates labor strength greatly, increases work efficiency, and guarantees personal safety; 3. this climbing ladder apparatus, requirement on machining accuracy is not high, and the tolerance ability is strong, and is easy for installation, easy to maintenance.

The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the vehicle-mounted climbing ladder apparatus that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1-Fig. 5, the vehicle-mounted climbing ladder apparatus of present embodiment is arranged on the compartment afterbody of construction machinery transporter, and it comprises cat ladder 3, activation lever 4, axle drive shaft 1, described axle drive shaft 1 is fixedly installed on the vehicle frame 6 by permanent seat 5, bearing fit between axle drive shaft 1 and the permanent seat 5; Activation lever 4 is fixed on the axle drive shaft 1 by self axle sleeve suit, and activation lever 4 connects hydraulic actuating cylinders 2, and hydraulic actuating cylinder 2 one ends are hinged on the vehicle frame 6, and the other end is hinged on the activation lever 4; Cat ladder 3 is sleeved on the axle drive shaft 1 by axle sleeve.
Described axle drive shaft 1 comprises cylindrical gooseneck 8, square-section axle 7, and cylindrical gooseneck 8 matches with permanent seat 5, and bearing fit between the permanent seat 5, and square-section axle 7 matches with the axle sleeve of activation lever 4 and the axle sleeve of cat ladder 3.The axle sleeve cross section of described cat ladder is identical with the square-section axle, radially slides cooperation along axle drive shaft between the two, can limit the cat ladder axle sleeve and can not rotate along the axle drive shaft axial line, but can move radially along axle drive shaft; The axle sleeve of activation lever 4 is fixedly installed on the square-section axle 7 of axle drive shaft 1.
The cross sectional shape of the axle base portion of described axle drive shaft 1 not only can be rectangle, can also be circular trough of belt or circular band projection or oblong or polygon, can not rotate along the axle drive shaft axial line as long as can limit the cat ladder axle sleeve, but can move radially just passable along axle drive shaft.
The upset of cat ladder 3 drives activation lever 4 by hydraulic actuating cylinder 2 and drives axle drive shaft 1, axle drive shaft 1 drives cat ladder 3 and realizes, owing to there are not other parts to be connected with cat ladder, cat ladder 3 can radially move freely along axle drive shaft 1, can satisfy the motor vehicles and machines of different wheelspans or the goods of different in width and move up and down applied range.
