Fig. 1 is a schematic structural diagram illustrating a cab spreader 100 according to an embodiment of the present invention in a use state; fig. 2 is a schematic structural diagram illustrating a cab spreader 100 in a storage state according to an embodiment of the present invention; fig. 3 shows a schematic diagram of the cab spreader 100 according to an embodiment of the present invention when lifting the cab 200.

Referring to fig. 1, 2 and 3, a cab spreader 100 according to an embodiment of the present invention includes a support frame 10 and a lifting beam 20. The lifting beam 20 has a rotation end 21 and a lifting end 22 opposite to each other in the longitudinal direction thereof, and the rotation end 21 is rotatably connected to the support frame 10 to switch the cab spreader 100 between the storage state and the use state. When the cab spreader 100 is switched to the storage state, one side surface of the lifting beam 20 in the longitudinal direction abuts against the support frame 10. When the cab spreader 100 is switched to the use state, the rotation end 21 of the lifting beam 20 abuts on the support frame 10, and the lifting end 22 of the lifting beam 20 is used to lift the cab 200.

The cab spreader 100 according to the present invention can ensure that the cab spreader 100 can stably lift the cab 200 by placing the lifting beam 20 in a use state when the cab 200 needs to be lifted by the lifting beam 20 that can rotate relative to the support frame 10 along the rotation axis a. When the lifting process is finished, one side surface of the lifting beam 20 along the longitudinal direction is attached to the support frame 10, so that the lifting beam is in a storage state, the overall occupied space of the cab spreader 100 is reduced, and the cab spreader 100 is easy to place.

Referring to fig. 1 and 2, in some embodiments, the plane of the supporting frame 10 is a reference plane, and when the cab spreader 100 is switched to the use state, the longitudinal direction of the lifting beam 20 is parallel to the reference plane. In this way, the lifting beam 20 is parallel to the reference plane in the use state, and the lifting beam 20 and the support frame 10 can be ensured to be parallel, so that the lifting beam 20 and the support frame 10 can apply force to the cab 200 in the same plane, and the cab 200 can be lifted smoothly. In particular, in some embodiments, the support frame 10 includes a first cross member 11 and a plurality of first side members 12 spaced apart from and disposed parallel to each other. The first cross member 11 is connected to a plurality of first longitudinal members 12 to configure a support frame 10, and the rotating end 21 of the lifting beam 20 is rotatably connected to the first cross member 11 or the first longitudinal members 12. In this way, the supporting frame 10 is formed by the first cross beam 11 and the plurality of first longitudinal beams 12, so that the overall strength of the supporting frame 10 can be improved, and the cab 200 can be lifted more safely and stably. In the present embodiment, the rotating end 21 of the lifting beam 20 is rotatably connected to the first cross member 11. Further, the first longitudinal beams 12 include two, and the two first longitudinal beams 12 are spaced from each other and arranged in parallel, and are connected to the first cross beam 11. Furthermore, the support frame 10 further includes a second cross member 13, two ends of the second cross member 13 are respectively connected to the two first longitudinal members 12, and the second cross member 13 and the first cross member 11 are spaced from each other and are arranged in parallel. In this way, the structural stability of the support frame 10 can be ensured by the second cross member 13, and the structural strength of the support frame 10 can be improved.

Referring to fig. 1, in some embodiments, the rotating end 21 of the lifting beam 20 has a rotation axis a, and the rotation axis a is perpendicular to the extending direction of the first cross beam 11. In particular, in some embodiments, the rotation axis a is perpendicular to both the reference plane and the direction of extension of the first crosspiece 11. In this way, when the cab spreader 100 is switched to the storage state, the length of the cab spreader 100 in the extending direction of the first longitudinal beam 12 can be reduced, and when the cab spreader 100 is switched to the use state, the force receiving direction of the lifting end 22 of the lifting beam 20 is perpendicular to both the extending direction of the first transverse beam 11 and the reference plane, so that the lifting beam 20 can be prevented from deflecting to cause unstable lifting when receiving force. In other embodiments, the rotation axis a may be perpendicular to the extending direction of the first beam 11 and parallel to the reference plane, which is not limited herein. Alternatively, the rotating end 21 of the lifting beam 20 is rotatably connected with the first cross beam 11 by a positioning pin, or the rotating end 21 of the lifting beam 20 is rotatably connected with the first cross beam 11 by a hinge. In addition, the rotating end 21 of the lifting beam 20 may be rotatably connected to the first cross beam 11 by other means, which is not limited herein.

Referring to fig. 2, in some embodiments, the cab spreader 100 further includes a locking member 30. When the lifting beam 20 is in the storage state, the locking member 30 penetrates through the first cross beam 11 and the lifting beam 20 to lock the first cross beam 11 and the lifting beam 20. In this way, the first cross member 11 and the lifting beam 20 can be locked by the locking member 30 when the lifting beam 20 is in the stored state, so that the lifting beam 20 is prevented from being released from the stored position and colliding with an external member. In particular, in some embodiments, the cab spreader 100 includes a first mating member 40 and a second mating member 50. The first fitting member 40 is connected to the first cross member 11, the second fitting member 50 is connected to the lifting beam 20, and the locking member 30 penetrates through the first fitting member 40 and the second fitting member 50 to lock the first cross member 11 and the lifting beam 20. In this way, additional tapping on the first cross beam 11 and the lifting beam 20 can be avoided by the first fitting member 40 and the second fitting member 50, thereby ensuring the strength of the first cross beam 11 and the lifting beam 20.

Referring to fig. 1 and 3, in some embodiments, the cab spreader 100 further includes a plurality of first slings 60. The plurality of first slings 60 are provided on the support frame 10 at intervals from each other in the circumferential direction of the support frame 10. Thus, the plurality of first hoisting rings 60 can be matched with a hoisting overhead traveling crane, and the hoisting force of the hoisting overhead traveling crane is transmitted to the first hoisting rings 60 through the hoisting rope, so that the force is applied to the support frame 10. Furthermore, the support frame 10 can be biased from a plurality of positions by the plurality of first hanging rings 60, thereby preventing the support frame 10 from being tilted or broken due to the biasing. In particular, in some embodiments of the present application, the first hanging ring 60 includes four first hanging rings 60, and the four first hanging rings 60 are disposed on the supporting frame 10 at intervals along the circumferential direction of the supporting frame 10. Further, lifting lugs 65 are respectively arranged at one end of the first cross beam 11, the lifting beam 20 and the first longitudinal beam 12 for lifting the cab 200. Thus, the stability of the cab 200 and the cab spreader 100 in the hoisting process can be further ensured.

Referring again to fig. 1 or 2, in some embodiments, the cab spreader 100 further includes a plurality of first stiffeners 71. Each first reinforcing member 71 is disposed between a corresponding first hanging ring 60 and the supporting frame 10. Thus, reinforcement can be provided at the stressed position of the cab spreader 100, and the support frame 10 is prevented from being broken. In the embodiment of the present application, the first reinforcement 71 includes four in order to be fitted to the first suspension ring 60. It should be noted that the cab spreader 100 includes a reinforcement assembly 70, and the reinforcement assembly 70 includes a first reinforcement 71. In some embodiments, the reinforcement assembly 70 further includes a second reinforcement 72 and a third reinforcement 73, wherein two ends of the second reinforcement 72 are connected between the adjacent first cross beam 11 and the first longitudinal beam 12, respectively, and two ends of the third reinforcement 73 are connected between the adjacent second cross beam 13 and the first longitudinal beam 12, respectively. In this way, the strength of the support frame 10 can be further reinforced by the second reinforcement 72 and the third reinforcement 73. In the embodiment of the present application, the second reinforcement 72 includes two, and the third reinforcement 73 includes two.

With continued reference to fig. 1 or fig. 2, in some embodiments, the reinforcing assembly 70 further includes a plurality of reinforcing beams 74 disposed parallel to and spaced apart from each other, and two ends of each reinforcing beam 74 are respectively connected to the two first longitudinal beams 12. Therefore, the force bearing effect of the support frame 10 is better, and the support frame 10 is prevented from being broken. In the embodiment of the present application, the reinforcing beam 74 includes two. Further, the cab spreader 100 further comprises a reinforcing longitudinal beam 75, and the reinforcing longitudinal beam 75 is connected between two adjacent reinforcing cross beams 74. In this way, the strength of the support frame 10 can be further increased by the reinforcing side members 75.

As shown in fig. 1 or 2, in some embodiments, the cab spreader 100 further includes a moving wheel 80, and the moving wheel 80 is provided on a side of the support frame 10 near the rotating end 21 of the lifting beam 20. In this way, when the support frame 10 is switched to the storage state by the moving wheels 80, the sliding friction of the cab spreader 100 can be converted into rolling friction by the moving wheels 80, thereby improving the convenience of moving the cab spreader 100. In particular, in some embodiments, the moving wheels 80 include universal wheels. The universal wheel structure can allow 360 degrees of horizontal rotation, thereby enabling the cab spreader 100 to be more easily oriented and thus able to travel more site-wise to a desired location. Further, the moving wheels 80 include at least two moving wheels 80, and the at least two moving wheels 80 are respectively disposed on two sides of the first longitudinal beam 12 along a direction perpendicular to the reference plane. In this way, when the cab spreader 100 is switched to the storage state, the cab spreader 100 can be supported more stably. Furthermore, the moving wheels 80 include three moving wheels 80, two moving wheels 80 are respectively disposed on two sides of the first longitudinal beam 12 in a direction perpendicular to the reference plane, and one moving wheel 80 is disposed on the first longitudinal beam 12.

Fig. 4 shows a schematic structural diagram of the abutment beam 90 of the cab spreader 100 according to an embodiment of the present invention.

As shown in fig. 4, in some embodiments, cab spreader 100 further comprises an abutment beam 90, abutment beam 90 being adapted to be suspended against cab 200. The abutting beam 90 is provided with a plurality of second hanging rings 92, and the second hanging rings 92 are arranged at intervals along the axial direction of the abutting beam 90. The second hoist ring 92 is used to be connected to the support frame 10 to hoist the cab 200. In this way, the support frame 10 can transmit force to the second suspension ring 92, and the contact beam 90 can provide support at the forward suspension position of the cab 200, thereby lifting the cab 200 more stably. In particular, in some embodiments, the second sling 92 includes two.

With reference to fig. 4 and fig. 3, in some embodiments, the cab spreader 100 further includes an abutting member 94, one end of the abutting member 94 is sleeved on the abutting beam 90, and the other end of the abutting member 94 has a profile shape adapted to the front suspension. Wherein the abutment 94 is movable in axial direction of the abutment beam 90 relative to the abutment beam 90 for abutment against the front suspension. In this way, the abutment 94 can reliably abut against the front suspension, thereby ensuring the stability of the lifting, and the abutment 94 can reliably apply force to the front suspension during lifting by abutting and matching with the front suspension when the front suspension has no lifting point. In some embodiments, the cab spreader 100 further includes a plurality of first stoppers 96, the first stoppers 96 are spaced from each other along the axial direction of the abutment beam 90, and the first stoppers 96 are used for limiting the movement of the abutment members 94. In this way, the ease of adjustment of the contact piece 94 can be ensured, and it is possible to avoid the problem that the movement range is too large, and it is difficult to perform adaptive adjustment according to the front overhang. In the embodiment of the present application, the first stopper 96 includes two. Further, the cab spreader 100 further includes a plurality of second limiting members 98, the second limiting members 98 are disposed at intervals along the axial direction of the abutting beam 90, and the second limiting members 98 are disposed on one side of the abutting beam 90 away from the supporting frame 10. Thus, when the abutment 94 rotates relative to the cab spreader 100, the cab spreader 100 is prevented from rotating beyond the second stopper 98 by the second stopper 98. In the embodiment of the present application, the second retaining member 98 includes two.

According to the cab spreader 100 provided by the embodiment of the application, the lifting beam 20 which can rotate along the rotation axis a relative to the support frame 10 enables the lifting beam 20 to be in a use state when the cab 200 needs to be lifted, and the cab spreader 100 can be ensured to stably lift the cab 200. When the lifting process is finished, one side surface of the lifting beam 20 along the longitudinal direction is attached to the support frame 10, so that the lifting beam is in a storage state, the overall occupied space of the cab spreader 100 is reduced, and the cab spreader 100 is easy to place. The lifting beam 20 is locked with the first cross beam 11 in the storage position by the locking member 30, so that the lifting beam can be prevented from being loosened. The force bearing effect of the support frame 10 can be improved through the reinforcing component 70, and the support frame 10 is prevented from being damaged or broken. The moving wheels 80 can be easily moved to a desired position when the cab spreader 100 is switched to the storage state. The abutting beam 90 can provide additional support for the front suspension part of the cab 200, so that the stability of the cab spreader 100 in lifting the cab 200 is further ensured, and the damage to the cab 200 is also avoided.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
