Problems solved by technology
At the same time, in order to prevent the pull rod from jumping out of the guide device due to the action of storm or other external forces, the design requirements of the guide device are very high, resulting in a large structure weight and increased energy consumption of related mechanisms, resulting in high economic costs.
In addition, the traditional tie rod guide device has high requirements on the manufacturing accuracy and installation accuracy of the tie rod structural parts, and it is very easy for the tie rod and the guide device to interfere with each other

Embodiment Construction
[0027] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.
[0028] At the same time, in order to clarify the crane pull rod guide device of the present invention more clearly, it is necessary to explain:
[0029] The first state of the crane pull rod guide means that the pull rod 1 is about to enter the initial state of the guide;
[0030] The second state of the crane rod guiding device refers to the state when the rod 1 enters the guiding device and just touches the anti-wear block 2;
[0031] The third state of the crane rod guiding device is the state when the guiding device starts to slowly retract under the gravity of the rod 1;
[0032] The fourth state of the crane rod guiding device is the state after the guiding device locks the rod 1.

The invention discloses a crane pull rod guide device. The crane pull rod guide device comprises two side plates oppositely arranged at intervals, and a guide plate arranged between the two side plates; the two ends of the guide plate are respectively hinged to the two side plates; the lower parts of the two side plates are both hinged to a front girder of a crane; springs are respectively arranged between the two side plates and the front girder; one ends of the springs are connected to the side plates, and the other ends of the springs are connected to the front girder; and the springs are always located in a compressed state. The crane pull rod guide device with the structure enables the two side plates arranged at intervals to be gradually gathered through self weight of a pull rod to finally firmly bond with the pull rod, only locks the pull rod through friction force between the side plates and the pull rod to prevent movement of the pull rod, and has the advantages of simple structure, light self weight, good adaptability, cost saving and lower requirements on production precision and installation precision of the pull rod.
Description
Technical field [0001] The invention relates to the field of hoisting machinery, in particular to a hoisting rod guide device. Background technique [0002] Tie rod guides are usually installed on the front girder of a quayside container crane. When the current girder is raised, the tie rods must be folded. The tie rod guides can allow the tie rods to be folded according to the designed folding method and angle without interference with surrounding parts. [0003] Traditional pull rod guides such as figure 1 As shown, in order to ensure that the pull rod can enter the slot, the opening needs to be made into a horn shape. At the same time, in order to prevent the pull rod from jumping out of the guide device due to storms or other external forces, the design requirements of the guide device are very high, resulting in a larger structural deadweight, increased energy consumption of related mechanisms, and higher economic costs. In addition, the traditional pull rod guide device has ...
