Description

Storage operating mechanism and folding crane

Technical Field

The invention relates to the technical field of hoisting equipment, in particular to a folding crane which is used on a vehicle or in the occasion of automobile repair and the like.

Background

The folding crane that current on-vehicle or vapour repair field used can set up the bolt in the below folding position of landing leg generally, and when normal use, the bolt is inserted on the hole site in the middle of landing leg and extension leg for landing leg and extension leg remain stable and crane's firm work, when needs folding, then extract the bolt, extension leg overturns, accomplishes the operation of accomodating. However, in the existing crane, 2 persons often need to operate at the same time when taking in due to self weight, so that the bolt can be pulled out, one person slightly lifts the crane at the rear, and the other person pulls out the bolt at the front, so that the operation is inconvenient.

Disclosure of Invention

Aiming at the problem that the folding crane in the prior art is inconvenient to operate during storage, the invention provides a novel storage operation mechanism and the folding crane with the same, which can realize one-man operation to finish folding storage of the crane.

In order to achieve the above object, the present invention provides a storage operation mechanism of a folding crane, the storage operation mechanism being mounted on a support member located between two fixed legs below a main body of the folding crane, the storage operation mechanism comprising:

a fixing plate fastened to the support member, the fixing plate being provided with a first hole site;

a pedal rotatably provided on the fixed plate;

a spindle assembly having a shaft passing through the pedal and mounted in a first hole of the fixed plate such that the pedal is rotatably movable about an axis of the shaft to at least a first position in which the pedal is free from the support and a second position in which the pedal is raised against the support.

In some examples, the pedal is generally L-shaped in configuration, having a corresponding pair of webs along the direction of the fixed plate and an arm plate secured thereto, the webs being provided with holes for the axle.

In some examples, the armplate is provided with a securing hole for receiving a pedal onto the body of the folding crane.

In some examples, the accommodating operation mechanism further comprises at least one roller sleeved on the shaft of the rotating shaft assembly.

In some examples, the fixing plates are arranged in pairs.

In some examples, the pair of securing plates are integrally formed.

In some examples, the shaft of the spindle assembly is configured as a pin.

In some examples, the latch is provided with a receptacle and a torsion spring latch passing through the receptacle.

According to the invention, a folding crane comprising any of the aforementioned storage operating mechanisms is also proposed.

By the technical scheme, the storage operating mechanism can enable a user to slightly lift the fixed support leg through the pedal, so that the compression state between the fixed support leg and the extension support leg (namely the movable folding support leg) is released, and a person can conveniently take out the bolt from the storage operating mechanism, and the operation is convenient. Further, still designed the rotatory structure of accomodating operating device, rotated out the footboard and used when using, when not using, can rotate the footboard and accomodate, avoid influencing the operation.

Meanwhile, the folding crane also designs the moving mechanism in the storage operation mechanism, so that the problem of difficult movement caused by the fact that the traditional folding crane only has a pair of wheels positioned below the main body after storage is solved, and convenience in movement after storage is realized through the roller with the integrated design.

Additionally, some aspects of the disclosure may be used alone or in any suitable combination with other aspects of the disclosure.

Referring to fig. 1 to 6, a folding crane according to the present disclosure includes a main body of the crane and a storage operation mechanism provided below the main body, wherein the storage operation mechanism is capable of being stored in a tilted state. Referring to fig. 1 to 6, the main body portion of the crane has a boom assembly, a hinge assembly, a hydraulic assembly, etc. of a general crane, and further has fixing legs 15, extension legs (i.e., storable legs) foldable to be stored in upper portions of the fixing legs, and a support 17 provided between the 2 fixing legs 15.

With reference to fig. 1-3, and 4-5, the stowing operation mechanism is operable by a user from the stowed condition to the open condition and then into the use condition (fig. 3) to slightly jack up the support 17 of the crane and slightly jack up the fixed leg 15, so that the compression between the fixed leg 15 and the extension leg 16 (i.e., the movably foldable leg) is released, thereby facilitating one person to remove the T-shaped latch 13 therefrom for operation without requiring 2 persons to perform simultaneous operations.

Referring to fig. 4 to 6, the folding crane storage operating mechanism includes a fixed plate 1, a pedal 2, and a rotating shaft assembly 3.

The fixed plates 1 are fastened to the supporting members 17, and the fixed plates 1 are oppositely provided with first hole sites 1A, respectively.

A pedal 2 rotatably provided on the fixed plate 1.

The rotating shaft assembly 3 is provided with at least one shaft penetrating through the pedal 2 and installed in a first hole position between the pair of fixed plates 1, so that the pedal 2 can rotate around the shaft of the rotating shaft assembly 3 to at least a first position and a second position, the pedal and the supporting piece are in a free state in the first position, the pedal jacks up the supporting piece in the second position, the effect of jacking up the fixed supporting leg is achieved, and the plug pin 13 is conveniently pulled out by one person.

In some embodiments, the receiving and operating mechanism of the present invention may be provided with one fixed plate, or may be provided with a plurality of fixed plates in pairs, the function of which is to provide rotational support and mounting of the pedal, the fixed plates being provided at two opposite intervals in the embodiments shown in fig. 1-6 as an exemplary illustration.

In connection with fig. 6, in this embodiment, the shaft 5 of the shaft assembly 3 penetrates the pedal 2 and then is located between the shaft and the corresponding first hole on the fixing plate 1, and in a specific embodiment, the shaft is configured as a pin, on which a hole (not shown) and a torsion spring pin 6 that can be inserted into the hole are provided, so as to fix the relative position of the shaft assembly with respect to the fixing plate, and in fig. 6, a washer 7 is preferably further provided and installed at one end of the pin to enhance the stability of the position of the pin.

Referring to fig. 6, the pedal 2 has an L-shaped overall structure and includes a pair of corresponding connection plates (2 a, 2 b) along the direction of the fixing plate and an arm plate 2c fixed thereto, and the connection plates are provided with holes adapted to the shaft assembly.

In connection with the figures, the connection plates 2a, 2b are arranged outside the fixing plate 1.
