detailed description

In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways than described here. Therefore, the present invention is not limited to the specific embodiments disclosed below. limit.

Embodiment 1, as shown in Fig. 1, Fig. 2, Fig. 3, and Fig. 4, this embodiment provides a vehicle-mounted multifunctional maintenance lifting platform. Guide rail 1. In this embodiment, the guide rail 1 is an I-shaped guide rail, and a mast-type lifting device is arranged on the guide rail 1. The structure of the mast-type lifting device provided in this embodiment is basically the same as that of a traditional mast-type lifting platform. , all include a fixed frame 2 for fixing on the guide rail 1 and a mast lifting mechanism 3 arranged on the fixed frame 2, and a center console 21 for controlling the work of the mast lifting mechanism 3 is also arranged on the fixed frame 2. The key improvement of the embodiment is also different from the traditional mast lifting platform in that in this embodiment, the mast lifting mechanism 3 is fixed on the fixed frame 2 in rotation. The advantage of this arrangement is that the mast lifting mechanism 3 When no work is needed, it can be laid flat, so that the overall height of the detection vehicle is reduced, and then it can pass through some height-limited places. In this embodiment, after considering the mast lifting mechanism 3 is brought down , it is necessary to support the mast lifting mechanism 3 at a certain angle so that it can be easily propped up. Therefore, in this embodiment, a support mechanism 4 for supporting the mast lifting mechanism 3 is provided between the two parallel guide rails 1. The side of the guide rail 1 away from the mast type lifting device is provided with a propping mechanism 5 for propping up the mast lifting mechanism 3 .

Wherein, the main function of the supporting mechanism 4 is to support the mast lifting mechanism 3 toppled over a certain angle of inclination, and the propping mechanism 5 is to lift the mast lifting mechanism 3 to a certain angle after the supporting mechanism 4 props up the mast lifting mechanism 3. Lifting mechanism 3 stands up, and after standing up, it provides a certain supporting effect. Of course, a limit baffle (not shown) for limiting the mast lifting mechanism needs to be set on the fixed frame 2 .

In this embodiment, the structure of the mast lifting mechanism 3 is basically the same as that of a traditional mast-type lifting mechanism, the mast lifting frame 31 and the workbench 32 arranged on the mast lifting frame 31, the mast lifting frame 31 There is technology, so in this embodiment, its mode of operation and specific structure are not described, and in this embodiment, a base (not marked in the figure) is provided at the bottom of the mast lifting frame 31, and the purpose of the base setting is to To realize the overall turning over of the mast lifting mechanism 3, in this embodiment, the lock and the propping mechanism 5 are used to cooperate with each other to realize the fixing of the mast lifting mechanism.

In this embodiment, the supporting mechanism 4 includes a jack 41 arranged between the two parallel guide rails 1 and a top plate 42 arranged on the top of the jack 41. The position of the jack 41 is arranged between the two parallel guide rails 1. In this embodiment , the jack 41 can be fixed on the carriage, and of course, can also be fixed on the guide rail 1 by means of bolts. End can be propped up slowly, similarly, in the process of jacking up, mast lifting frame 31 is in an inclined state, therefore, in the present embodiment, top plate 42 is arranged on the top of jack 41 obliquely, specifically, The top plate 42 is arranged on the top of the jack 41 at a 30° inclination.

Of course, the support mechanism 4 can also be selected in a manner of its structure, for example, it is also possible to use a screw lifting method to replace the jack, but, considering the angle of saving time and effort, the jack structure is preferably used.

The propping mechanism 5 then includes a fixed seat 51 arranged on the guide rail 1 and a hydraulic cylinder 53 which is rotatably fixed on the fixed seat 51. The fixed seat 51 is provided with a groove 52 for placing the hydraulic cylinder 53. In this embodiment , the fixing seat 51 is arranged in a cuboid structure, and a groove 52 is arranged at its central position, and the hydraulic cylinder 53 is arranged in the groove 51. When the mast lifting mechanism 3 needs to work, the support mechanism 4 starts to work, and the After the mast lifting frame 31 is jacked up to a certain angle, then the hydraulic cylinder 52 starts to work, and the mast lifting frame 31 is propped up to withstand it.

Considering that the hydraulic cylinder 53 needs to maintain an inclined angle when propping up the mast lifting frame 31, but when the mast lifting frame 31 is toppled over, the hydraulic cylinder 53 will be in a horizontal state. Therefore, in this embodiment, in the concave A support rod 54 for supporting the hydraulic cylinder 53 is also provided in the groove 52, and the support rod 54 is telescopically arranged in the groove 52. Specifically, a crank handle for controlling the expansion and contraction of the support rod 54 is provided on one side of the fixing seat 51. 55. The control mode of the crank handle 55 is also realized by using a screw rod. Similarly, in order to realize the tilting and leveling of the hydraulic cylinder, in this embodiment, the power end of the hydraulic cylinder 53 is hinged with the mast lifting mechanism 3 .

In this embodiment, in order to facilitate maintenance, the propping mechanism 5 is movably fixed on the guide rail, that is, the propping mechanism 5 is detachably arranged on the guide rail 1 .

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention to other forms. Any skilled person who is familiar with this profession may use the technical content disclosed above to change or remodel it into an equivalent change. The embodiments are applied to other fields, but any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solutions of the present invention without departing from the content of the technical solutions of the present invention.
