[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0031] At the same time, the meaning of "and / or" or "and / or" appearing in the full text includes three options. Taking "A and / or B" as an example, it includes option A, or option B, or a option in which both A and B are satisfied.
[0032] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model. Example 1
[0033] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a cab hoisting mechanism, which includes a frame 1, an electric push rod 2 installed on the top of the frame 1, a support frame 3 installed at the output end of the electric push rod 2, a winding roller 4 installed on the top of the support frame 3, and a traction rope 5 wound on the surface of the winding roller 4. A bearing plate 51 is installed on the surface of the support frame 3, and a wire management member 6 is provided inside the bearing plate 51;
[0034] The wire management component 6 includes a motor 61 and a baffle 62 installed inside the supporting plate 51. The motor 61 is located on the outside of the baffle 62. The baffle 62 is provided with two groups. The inner side of the baffle 62 is rotatably connected to a twisted shaft 63. The output end of the motor 61 extends to the inside of the baffle 62 and is fixedly connected to the twisted shaft 63. The baffle 62 is fixed inside the supporting plate 51, and an external power supply can be installed on the outside of the winding roller 4 to drive the winding roller 4 to rotate. A groove is opened inside the supporting plate 51, and the wire management component 6 is located inside the groove.
[0035] A slider 64 is movably sleeved on the surface of the twisted shaft 63, and a guide block 65 is movably connected inside the slider 64. The guide block 65 is located on the surface of the twisted shaft 63 and is movably connected thereto. The guide block 65 is movably connected to a thread on the surface of the twisted shaft 63. Since the thread on the surface of the twisted shaft 63 is bidirectional, the slider 64 can be driven to perform reciprocating motion.
[0036] A limit block 66 is fixedly connected to one side of the slider 64, and the guide block 65 is located at one end of the limit block 66 and is movably connected thereto. The limit block 66 can limit the guide block 65 so that it always maintains a state of threaded contact with the twisted shaft 63 and prevents the guide block 65 from detaching from the slider 64.
[0037] A connecting rod 67 is fixedly connected to one side of the slider 64 and away from the limit block 66, and an anti-winding part 7 is fixedly connected to one end of the connecting rod 67 and away from the slider 64. A limiting block 69 is fixedly connected to the other side of the anti-winding part 7. The connecting rod 67 can connect the anti-winding part 7 to the twisted shaft 63.
[0038] A slide bar 68 is fixedly connected to the inner side of the two sets of baffles 62 and on one side of the twisted shaft 63. A limiting block 69 is located on the surface of the slide bar 68 and is movably connected to it. The setting of the slide bar 68 and the limiting block 69 can prevent the slider 64 from shifting during movement.
[0039] During use, the motor 61 and the external power supply can be started at the same time to drive the twisted shaft 63 and the winding roller 4 to work at the same time. When the motor 61 is running, it will drive the twisted shaft 63 to rotate. Since the surface of the twisted shaft 63 is provided with two sets of opposite threads, when it rotates, the guide block 65 inside the slider 64 will move along the rotation of the twisted shaft 63. When it rotates to one end of the twisted shaft 63, the guide block 65 will move along the other set of threads, thereby driving the guide block 65 to reciprocate, thereby driving the anti-winding part 7 to reciprocate, and the traction rope 5 can be reciprocated along the surface of the winding roller 4, so that the traction rope 5 can be evenly laid on the surface of the winding roller 4, further solving the problem of the traction rope 5 being tied or entangled, and further extending the service life of the traction rope 5. Example 2
[0040] Reference Figure 1-5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:
[0041] The anti-winding part 7 includes an outer ring 71 fixed at one end of the connecting rod 67, the interior of the outer ring 71 is fixedly connected to a fixing rod 72, one end of the fixing rod 72 and the end away from the outer ring 71 is fixedly connected to an inner ring 73, the outer ring 71 and the inner ring 73 are fixedly connected by the fixing rod 72, the fixing rods 72 are arranged in a ring array, the interior of the outer ring 71 is movably sleeved with an adaptor 74, the inner ring 73 can provide support for the adaptor 74, and can limit the traction rope 5, and the traction rope 5 is located inside the inner ring 73.
[0042] The adaptor 74 includes a moving rod 741 movably sleeved inside the outer ring 71, a spring 742 is sleeved on the surface of the moving rod 741, one end of the spring 742 is fixedly connected to the inner side of the outer ring 71, and the other end of the spring 742 is fixedly connected to the moving rod 741. The spring 742 can make the moving rod 741 have elastic force to organize the traction rope 5.
[0043] An arc-shaped plate 744 is provided on the inner side of the inner ring 73, one end of the moving rod 741 extends to the inside of the inner ring 73 and is fixedly connected to the arc-shaped plate 744, an anti-slip ring 743 is provided on the outer side of the outer ring 71, the other end of the moving rod 741 and the end away from the arc-shaped plate 744 extends to the outside of the outer ring 71 and is fixedly connected to the anti-slip ring 743, the anti-slip ring 743 can prevent the moving rod 741 from detaching from the outer ring 71, and the arc-shaped plate 744 is arc-shaped, which can facilitate the arrangement of the traction rope 5.
[0044] During use, the winding roller 4 is driven in the reverse direction by an external power supply to rotate, and the traction rope 5 is driven to rise along the surface of the arc plate 744. During the rising process, if there is shaking, it will first collide with the arc plate 744. During the movement of the arc plate 744, the moving rod 741 will be driven to move along the inner ring 73 and the inner ring 71. At the same time, the spring 742 will be deformed. Since the spring 742 is elastic, it can quickly restore the deformation and drive the moving rod 741 to drive the arc plate 744 to move toward the direction of the traction rope 5, so as to quickly maintain the stability of the traction rope 5, so that the operation can be carried out more smoothly.
[0045] In summary, the spring 742, as an elastic element, can absorb or release energy when the traction rope 5 rises or falls, thereby playing a role of buffering and supporting. When the traction rope 5 rises or falls, the spring 742 will drive the moving rod 741 to automatically adjust its length according to the movement state of the traction rope 5, thereby adjusting the tension. Moreover, since the arc plate 744 fits the traction rope 5, the friction can be reduced, allowing the traction rope 5 to pass more smoothly, thereby ensuring the stability and accuracy of the tension adjustment.
[0046] The remaining structures are the same as those of Example 1.
[0047] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
