Detailed Description

The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in combination with embodiments.

According to one aspect of the present application, there is provided a gantry hook apparatus, wherein the gantry hook apparatus includes a gantry hook assembly 10, a driving unit 20, a limiting mechanism 30 and a mounting base 40, the gantry hook assembly 10 includes a joint plate 11, a gantry hook 12 and a rotating shaft 13 respectively fixed to the joint plate 11, the gantry hook assembly 10 is rotatably mounted to the mounting base 40, the driving unit 20 is used for driving the rotating shaft 13 to rotate, and the limiting mechanism 30 is mounted to the mounting base 40 and is used for positioning the gantry hook assembly 10 relative to the mounting base 40 after the gantry hook assembly 10 rotates in place.

With the gantry hook apparatus of the present application, the rotation shaft 13 can be driven by the driving unit 20, so as to drive the gantry hook 12 to conveniently adjust the direction. After being adjusted in place, the gantry hook assembly 10 can be positioned relative to a mount that is fixed to the crane main beam 60 by the stop mechanism 30 to meet the requirements of being fixed relative to the crane main beam 60 in use.

The driving unit 20 may take various suitable forms to drive the rotation shaft 13 to rotate. For example, the driving unit 20 may include a motor 21, a first gear 22 mounted to an output shaft of the motor 21, and a second gear 23 engaged with the first gear 22 and fixed to the rotation shaft 13.

To obtain a stable structure, the engagement plate 11 and the mounting seat 40 may be centrally disposed, the mounting seat 40 has an inner space and a bottom center through hole communicating with the inner space to allow the rotation shaft 13 to be inserted, the motor 21 may be disposed outside the mounting seat 40, and a sidewall of the mounting seat 40 is provided with a relief hole to allow the first gear 22 and/or the second gear 23 to pass therethrough.

In this application, the limiting mechanism 30 can limit the proper components of the gantry hook assembly 10 (e.g., the splice plate 11, the gantry hook 12, the shaft 13) to limit the overall assembly. The spacing mechanism 30 may take a variety of suitable forms, depending on the need and spacing arrangement, so long as it is capable of positioning the gantry hook assembly 10 after it is rotated into place.

In a preferred embodiment of the present application, as shown in fig. 1 to 3, the limiting mechanism 30 may include a limiting gear 31, a chuck 32, and a pushing unit for pushing the chuck 32 to be in or out of snap-fit with teeth of the limiting gear 31, where the limiting gear 31 is fixed to the rotating shaft 13. When the gantry hook assembly 10 rotates in place, the pushing unit can push the clamping head 32, and the clamping head 32 is pushed to the position in which the teeth of the limiting gear 31 are in clamping fit, so that the rotation of the limiting gear 31 and the rotating shaft 13 is limited, and the effect of limiting the rotation of the gantry hook assembly 10 (especially preventing the rotating shaft 13 from rotating due to careless rotation of the motor 21) is achieved.

The pushing unit may take a suitable form so as to be able to push the chuck 32 to move into a position of engagement with the limiting gear 31, thereby enabling the chuck 32 to reach a limiting state of engagement with the limiting gear 31. And, the chuck 32 can be driven by the pushing unit to reach a state of releasing the limit gear 31, that is, the chuck 32 can be switched between the limit state and the state of releasing the limit by the operation of the pushing unit. For example, the pushing unit may be in a form capable of linearly expanding and contracting (for example, an expansion cylinder, a push rod, or the like) to push the chuck 32 into a limit state of engagement with the limit gear 31 by extension, and to bring the chuck 32 to a release limit state of being away from the limit gear 31 by retraction.

Preferably, in order to be able to stably adjust the gantry hook assembly 10 in a state where the limit gear 31 and the chuck 32 are disengaged, the pushing unit may be configured to elastically push the chuck 32 in a state where the limit is disengaged. That is, in the state of releasing the limit (i.e., the position of the chuck 32 is not completely restricted, and can be easily released from engagement with the limit gear 31), the chuck 32 is always elastically pushed against the limit gear 31, so that the limit gear 31 can eject the chuck 32 outward to completely release the snap fit against the interference of the chuck 32 while rotating when the rotating shaft 13 is rotated, and when the limit gear 31 rotates one tooth, the chuck 32 can be elastically pushed against to automatically return to the limit state, that is, an appropriate resistance is provided thereto during the rotation of the limit gear 31, so that the rotation of the gantry hook assembly 10 is smooth and controllable.

In order to achieve stable stopper in the stopper state and elastic stopper in the stopper-released state, the stopper unit may have a member capable of rigidly pushing the chuck 32 and a member elastically pushing the chuck 32. Specifically, in the embodiment shown in fig. 2, the pushing unit includes a telescopic cylinder 33 that pushes against the chuck 32 and a biasing member 34 for biasing the chuck 32 toward the limit gear 31. The telescopic cylinder 33 is used for rigidly pushing against the chuck 32, rigidly maintaining the chuck 32 in a limited state by extending, and being capable of disengaging from contact with the chuck 32 by retracting to cancel the rigid limit of the chuck 32 (i.e., putting the chuck 32 in a contact limited state). The biasing member 34 is capable of applying a biasing force to the chuck 32 toward the limit gear 31 in the released limit state so that the chuck 32 provides resistance to the rotation of the limit gear 31.

When it is desired to rotate the shaft 13 to adjust the orientation of the gantry hook assembly 10, the telescoping cylinder 33 is first retracted such that the telescoping cylinder 33 is out of contact with the chuck 32, and the chuck 32 is in an unlocked state but is still held in engagement with the limit gear 31 by the biasing member 34. Subsequently, the rotating shaft 13 can be driven to rotate, the limiting gear 31 overcomes the interference of the clamping head 32 and simultaneously pushes out the clamping head 32 outwards when rotating until the rotating shaft 13 rotates in place, the clamping head 32 can be elastically pushed to automatically return to a limiting state meshed with teeth, and finally the telescopic cylinder 33 stretches and contacts the clamping head 32 to provide rigid limiting for the clamping head 32.

To ensure linear movement of the chuck 32, guidance may be provided for movement of the chuck 32. Specifically, as shown in fig. 2, the pushing unit may include a mounting frame 35 mounted on the mounting base 40, a sliding plate 36, and a sliding rod 37 having both ends respectively fixed to the mounting frame 35 and the mounting base 40, wherein the chuck 32 is fixed to the sliding plate 36, and the sliding plate 36 slides through the sliding rod 37.

In addition, the force of the telescopic cylinder 33 and the biasing member 34 may be applied to the chuck 32 through the slide plate 36. Also, depending on the positions of the respective related components, the respective components of the stopper mechanism 30 may be specifically arranged. Specifically, the connection plate 11 and the gantry hook 12 may be disposed below the mounting seat 40, the rotating shaft 13 may be inserted into an inner space of the mounting seat 40, the limiting gear 31 may be disposed in the inner space of the mounting seat 40, the mounting frame 35, the biasing member 34, and the telescopic cylinder 33 may be disposed outside the mounting seat 40, the mounting frame 35 may be fixed on a side wall of the mounting seat 40, a through hole allowing the chuck 32 to pass through is disposed on the side wall of the mounting seat 40, the biasing member 34 may include a spring, one end of the spring is connected to the outside of the mounting seat 40, the other end is connected to one side of the sliding plate 36 facing the mounting seat 40, and the telescopic cylinder 33 is mounted on the mounting frame 35 and is disposed to be capable of pushing against the other side of the sliding plate 36.

Wherein a plurality of springs may be provided to facilitate providing a uniform biasing force to biasing member 34, the plurality of springs may be evenly distributed about chuck 32. Preferably, a plurality of slide bars 37 may also be provided, with a spring surrounding each slide bar 37 to more stably guide movement of the chuck 32 while applying a uniform biasing force. Also, the telescopic cylinder 33 may be provided to be telescopic in alignment with the chuck 32. Specifically, in the preferred embodiment shown in fig. 2, the chuck 32 is disposed at the center of the slide plate 36, the telescopic cylinder 33 is telescopic in alignment with the center of the slide plate 36, the plurality of springs of the slide rod 37 and the biasing member 34 are uniformly distributed around the chuck 32, and the slide plate 36 is provided with a plurality of through holes around the center to allow the slide rod 37 to pass therethrough.

The chuck 32 may include a chuck body 321 for engaging with teeth of the limiting gear 31 and a connecting rod 322 for connecting the chuck body 321 with the sliding plate 36, and in the moving process of the chuck 32, the chuck body 321 always moves in an inner space of the mounting seat 40, and only the connecting rod 322 penetrates through a side wall of the mounting seat 40, so that the chuck body 321 can be protected as much as possible, and the chuck body is prevented from being damaged by external factors to affect the engagement with the limiting gear 31. Wherein the chuck body 321 is shaped to mate with the teeth of the limit gear 31, for example, to have an isosceles trapezoid cross section.

In this application, in order to facilitate driving the rotating shaft 13, the gravity borne by the rotating shaft 13 should be reduced, for this purpose, the gantry hook apparatus may include a carrying plate 50 fixed on the mounting base 40, the carrying plate 50 is provided with a sliding slot 51, and the engagement plate 11 is provided with a sliding block 111 matched with the sliding slot 51, so that when the gantry hook assembly 10 rotates, the sliding block 111 slides along the sliding slot 51 and is carried by the sliding slot 51. By arranging the bearing plate 50, the bearing plate 50 can bear most of the gravity load of the gantry hook assembly 10 through the cooperation of the sliding groove 51 and the sliding block 111, so that the gravity borne by the rotating shaft 13 is reduced, and the rotating shaft 13 is convenient to rotate. In addition, the runner 51 and the slider 111 may have a suitable structural form to cooperate with each other in a load-bearing manner while guiding the slider 111 through the runner 51, for example, the runner 51 may be a runner of T-shaped cross section, and the slider 111 may be a corresponding slider of T-shaped cross section.

Wherein the shape and position of the chute 51 should be adapted to the trajectory of the slide 111 during rotation of the gantry hook assembly 10. For example, the sliding blocks 111 may be disposed at least two around the rotation center of the gantry hook assembly 10, and the sliding grooves 51 may include an arc shape corresponding to the movement range of each sliding block 111, or the sliding grooves 51 may be ring-shaped corresponding to the distribution circumference of the sliding blocks 111.

In addition, during use, it may also be necessary to adjust the direction of the hook opening of the gantry hook 12, for example from a direction in which both hook openings advance as shown in fig. 1 to a direction in which the hook openings face each other. For this purpose, the gantry hook 12 is preferably fixed to the joint plate 11 in such a manner that the hook direction of the gantry hook 12 is adjustable, so that different hook direction settings can be accommodated by adjusting the fixed position of the gantry hook 12 relative to the joint plate 11.

Wherein the gantry hook 12 can be provided to the joint plate 11 in various suitable ways to achieve adjustability of the hook opening. In a preferred embodiment of the present application, as shown in fig. 1, 4 and 5, the gantry hook assembly 10 may include a connection sleeve 14 sleeved on the top end of the gantry hook 12, a jack 141 communicating with the inner cavity of the connection sleeve 14 is disposed on the outer periphery of the connection sleeve 14, at least two slots 121 capable of being aligned with the jack 141 are disposed on the outer periphery of a portion of the gantry hook 12 sleeved in the connection sleeve 14, and the connection plate 11 is mounted with a plug 112 capable of being inserted into or withdrawn from the slots 121 through the jack 141. In use, the gantry hook 12 can be secured to the connector plate 11 by inserting the connector 112 into the slot 121 through the receptacle 141. When the direction of the hook opening needs to be adjusted, the plug connector 112 can be pulled out of the slot 121, then the gantry hook 12 can be rotated relative to the connecting sleeve 14 to adjust the direction of the hook opening, and after the hook opening is adjusted in place, the other slot 121 is just aligned with the jack 141, so that the gantry hook 12 can be fixed on the connecting plate 11 again by reinserting the plug connector 12.

In order to facilitate the observation of whether the socket 121 is aligned with the jack 141 during operation, a portion of the outer wall of the connecting sleeve 14 may be hollowed out.

It will be appreciated that, in order to achieve a secure connection of the gantry hook 12 to the adapter plate 11 by means of the plug-in connection 112, the portion of the plug-in connection 112 that is inserted into the slot 121 through the insertion hole 141 should have dimensions corresponding to those of the insertion hole 141, the slot 121, in order to ensure a secure plug-in fit.

In this application, the plug-in connector 112 may be plugged in an appropriate manner, for example, the plug-in connector 112 may be plugged in by a telescopic cylinder. To simplify the structure, as shown in fig. 4, the plug 112 may include a fixing base 112a, a bolt portion 112b and a plug post 112c, the fixing base 112a is fixed to the bottom of the connector 11, the fixing base 112a is provided with a screw hole matching with the screw thread of the bolt portion 112b, and the plug post 112c is provided at the free end of the bolt portion 112 b. In use, the bolt 112b can be rotated by the head of the bolt 112b, so that the bolt 112b drives the plug-in post 112c to move to complete the insertion or extraction operation. The two gantry hooks 12 may be provided with corresponding connectors 112, and the two fixing bases 112a may be disposed at positions between the two gantry hooks 12, so that the two bolt portions 112b are rotated to approach each other to pull out the plug-in post 112c, and the two bolt portions 112b are rotated to separate from each other to insert the plug-in post 112c.

Since the direction of the hook opening of the gantry hook 12 is generally selected between the advancing direction shown in fig. 1 and the opposite direction rotated 90 degrees from the direction shown in fig. 1, the gantry hook 12 is provided with two of the slots 121 distributed at 90 degrees as shown in fig. 5 for both cost and efficiency. By selecting a different slot 121 for insertion of the plug 112, it is possible to switch between the hook advance and the hook opposite direction.
