The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The application discloses detachable carrier lifting devices, including lifting column 11 and installing the supporting mechanism 112 in lifting column 11 bottom, be equipped with the coupling assembling 30 that is used for installing tie-beam 20 on the supporting mechanism 112, tie-beam 20 is used for connecting a plurality of carrier lifting devices, and coupling assembling 30 includes:
a connecting upper seat 31 and a connecting lower seat 32, one of which is fixedly connected with the supporting mechanism 112 and has an operating state of clamping and positioning the connecting beam 20 and a release state of being away from each other to allow the connecting beam 20 to be separated from the connecting assembly 30;
and a locking member 33 mounted on the coupling upper seat 31 or the coupling lower seat 32 for maintaining the coupling upper seat 31 and the coupling lower seat 32 in an operating state.
The connecting assembly 30 is used for realizing the detachable installation of the supporting mechanism 112 and the connecting beam 20, and the portability and the stability of the carrier lifting device are considered. When the upper connecting seat 31 and the lower connecting seat 32 are in an operating state, the connecting beam 20 and the supporting mechanism 112 are mutually positioned, so that a stable stress system is constructed, and the stable arrangement of the lifting column 11 in space is realized. The operation of connecting the upper seat 31 and the lower seat 32 is realized by the locking member 33, and the locking member 33 should in principle avoid directly bearing the lifting load and avoid the possibility of locking failure.
In the specific arrangement of the locking member 33, referring to an embodiment, the upper connecting seat 31 and the lower connecting seat 32 are connected by a hinge 301, one of the upper connecting seat 31 and the lower connecting seat 32 is provided with the locking member 33 on a side away from the hinge 301, and the other is provided with a locking rib 302 engaged with the locking member 33.
The locking ribs 302 function to achieve an even distribution of the locking torque and a positioning function of the locking member 33, thereby enhancing the effect of locking of the locking member 33.
The locking rib 302 may be provided in various shapes, for example, as a flat bearing surface for more stably achieving engagement with the locking member 33. It is also possible to refer to an embodiment in which the locking rib 302 comprises a positioning ramp 303 for cooperating with the locking member 33, the positioning ramp 303 being directed towards the hinge 301, the width of the positioning ramp 303 cooperating with the locking member 33.
The positioning slope 303 can ensure the stability of the locking member 33 in the locked state. In the present embodiment, the positioning slope 303 is disposed toward the hinge 301, that is, the direction of the force applied to the locking element 33 in the process of determining the slope fit at least includes a component force toward the hinge 301, so as to avoid an unexpected failure of the locking state of the locking element 33. The width of the positioning slope 303 and the locking piece 33 cooperate with each other to realize the positioning of the locking piece 33 by the positioning slope 303. For example, as shown in fig. 1c, the platforms on both sides of the positioning slope 303 limit the locking element 33, and the locking element 33 cannot move along the positioning slope 303 when in the locked state, thereby improving the stability of the operation of the locking element 33.
In terms of establishing the locking moment of the locking member 33, referring to an embodiment, a locking anchor 331 is disposed on one of the upper connecting seat 31 and the lower connecting seat 32, the locking member 33 includes a screw rod 333 having one end hinged to the locking anchor 331 and a pressing member 332 moving on the screw rod 333, and the pressing member 332 cooperates with the positioning slope 303 to maintain the upper connecting seat 31 and the lower connecting seat 32 in the working state.
In this embodiment, applying a force to one of upper connection seat 31 and lower connection seat 32 is achieved by locking anchor 331 and pressing member 332, thereby achieving mutual approaching of upper connection seat 31 and lower connection seat 32. The locking piece 33 can hold the coupling upper seat 31 and the coupling lower seat 32 in the operating state, and also can clamp the coupling beam 20 by the coupling upper seat 31 and the coupling lower seat 32, thereby providing a friction force in the axial direction of the coupling beam 20 and improving the stability.
In the arrangement of the pressing member 332, the pressing member 332 and the locking rib 302 are pressed by the screw kinematic pair with the screw 333, but the simultaneous rotation and axial movement of the screw kinematic pair has a certain effect on the operation of the pressing member 332. Referring to an embodiment, the pressing member 332 includes a force applying member 3321 threadedly engaged with the screw 333 and an engaging member 3322 engaged with the positioning inclined surface 303, the engaging member 3322 is provided with an inwardly retracted engaging region 3323 on a side facing the locking rib 302, a side wall of the engaging region 3323 includes an engaging surface 3324 engaged with a side wall of the locking rib 302 and an engaging surface 3325 engaged with the positioning inclined surface 303, and the engaging member 3322 can move in the axial direction of the screw 333 and transmit the force of the force applying member 3321 to the positioning inclined surface 303.
In this embodiment, the engaging piece 3322 and the force applying piece 3321 are independently disposed to avoid the problem that the rotation and the axial movement occur simultaneously in the screw kinematic pair, and the engaging piece 3322 realizes the rotation stop relative to the screw 333 through the engaging surface 3324 of the engaging area 3323, thereby realizing the better engaging effect of the engaging surface 3325 and the positioning inclined surface 303, and improving the stability of the whole product while improving the locking effect of the locking piece 33.
As mentioned above, the upper connecting seat 31 and the lower connecting seat 32 can achieve the positioning effect by applying pressure to the outer peripheral surface of the connecting beam 20, and in an embodiment, the upper connecting seat 31 and/or the lower connecting seat 32 is provided with a first positioning hole 304, the connecting beam 20 is provided with a plurality of second positioning holes 201, and when the connecting beam 20 is matched with the connecting assembly 30, the first positioning hole 304 is aligned with one of the second positioning holes 201.
The first positioning hole 304 and the second positioning hole 201 can be aligned to form a positioning pin (not shown) in a penetrating manner, so that the rigid connection among the upper seat 31, the lower seat 32 and the connecting beam 20 is realized, and the stability can be effectively improved when the carrier lifting device is stressed. The increase in the number of the second positioning holes 201 can also improve the adaptability and facilitate fine adjustment. The second positioning holes 201 may be independent holes as shown in the drawings, or may be elongated guide grooves with limiting holes.
In the specific shape of the upper connecting seat 31 and the lower connecting seat 32, referring to an embodiment in which the lower connecting seat 32 has a U-shaped cross section and an open interior for receiving the connecting beam 20, the upper connecting seat 31 is configured as follows:
the section is U-shaped and surrounds the connecting beam 20 with the connecting lower seat 32; or
The sectional shape is a shape of one and closes the opening of the connection lower seat 32 to wrap the connection beam 20.
The lower coupling seat 32 is formed in a U shape as a member for supporting the coupling beam 20, and can improve the stability of the coupling beam 20 by accommodating the coupling beam 20. The upper connecting seat 31 is U-shaped and wraps the connecting beam 20, so that acting force can be more uniformly distributed to the connecting beam 20 and effective stress points of the supporting mechanism 112, and the connecting stability is improved; the connecting upper seat 31 is in a shape of one, so that the weight of the connecting upper seat 31 can be reduced, and the operation is convenient.
As described above, the connection beam 20, the connection assembly 30 and the support mechanism 112 constitute a support system connected with each other, thereby achieving a stable arrangement of the lifting column 11. In an embodiment, at least two connecting assemblies 30 are disposed on the connecting mechanism, each connecting assembly 30 connects different connecting beams 20, and the extending directions of the different connecting beams 20 are different.
The coupling beams 20 having different extending directions can provide a larger projected area in the gravity direction under the condition of the same material, weight and volume, thereby providing a more stable supporting effect.
The different arrangements will be explained with reference to the specific structure, and referring to fig. 1c, the connection lower seat 32 indicated at a is connected to the support mechanism 112 and provided with a locking anchor 331 for connecting the locking member 33, and the other side is provided with a hinge 301, the connection upper seat 31 is connected to the hinge 301, and the other side is engaged with the locking member 33 by bypassing the connection beam 20. In other embodiments, the positions of the locking anchor 331 and the hinge 301 may be reversed, and the position of the locking flange may be adjusted accordingly.
Referring to fig. 1c, the connecting lower seat 32 indicated at B is connected to the supporting mechanism 112 and has a hinge 301 on one side, and a locking anchor 331 for connecting the locking member 33 on the other side, and the connecting upper seat 31 is connected to the hinge 301 on one side and engaged with the locking member 33 by bypassing the connecting beam 20 on the other side. In other embodiments, the positions of the locking flange and the hinge 301 may be reversed, and correspondingly, the position of the locking anchor should be adjusted accordingly.
In a practical product, the two connection modes can be combined as required, thereby realizing different technical effects. For example, as shown in fig. 1c, the two connecting members 30 are connected in different ways, mainly considering the convenience of the different connecting beams 20 during the connection process, and avoiding the mutual interference between the connecting members 30. In addition to the alternative of the snap-fit of the connecting members 30, the positions of the locking members 33 of the two connecting members 30 may be the same or different as desired. Referring to fig. 1c, the locking members 33 of the two connecting members 30 are disposed at different positions, wherein a is a position where the locking member 33 is disposed on a side of the connecting member 30 close to the supporting mechanism 112, and B is a position where the locking member 33 is disposed on a side of the connecting member 30 away from the supporting mechanism 112. In keeping with the above, the main consideration is the ease of handling of the various coupling beams 20 during the coupling process, while also avoiding interference between the coupling assemblies 30. The specific settings can be adjusted according to the actual requirements of the product.
In the installation and installation of the connection assembly 30, referring to fig. 2c, the support mechanism 112 is provided with an installation structure 34 for installing a corresponding structure, and the installation structure 34 and the connection assembly 30 can be connected by welding, bolts, or by inserting or other structures which are convenient to detach, so as to further improve the detachability of the product, thereby facilitating storage and transportation.
With reference to fig. 2a, the connecting assembly 30 is taken as an example, and a specific operation process of the connecting assembly 30 is exemplarily explained. When it is desired to effect the mounting of the connecting assembly 30 and the connecting beam 20:
firstly, the connecting assembly 30 needs to be opened, the connecting assembly 30 is in a locking state by default in the storage and transportation process, and the upper seat 31 and the lower seat 32 can be connected in a loss mode in the storage and transportation process; the movement stroke of the engagement piece 3322 is released by rotating the force applying piece 3321 of the locking piece 33, and when the movement stroke of the engagement piece 3322 can allow the engagement surface 3325 to be disengaged from the locking slant, the screw rod 333 is rotated about the locking anchor point 331 as the rotation axis, and at this time, the locking of the connection upper seat 31 is released, and the operator manually opens the connection upper seat 31;
secondly, mounting the connecting beams 20, placing the corresponding connecting beams 20 into the connecting lower seats 32, adjusting the relative positions between the positioning holes, manually closing the connecting upper seats 31 after confirmation, and positioning the connecting beams 20 through positioning pins (not shown), wherein the positioning pins can prevent the connecting beams 20 from relatively displacing relative to the connecting assembly 30 in the locking process of the connecting assembly 30;
finally, the connecting assembly 30 is locked, the screw rod 333 is rotated with the locking anchor 331 as a rotation axis and the position of the engaging piece 3322 is adjusted until the side wall of the locking protrusion 302 is attached to the engaging surface 3324, the positioning inclined surface 303 is attached to the engaging surface 3325, and then the force applying piece 3321 is rotated to press the engaging piece 3322, so as to lock the upper seat 31 and the lower seat 32. The specific force applying member 3321 locking torque in this step can be adjusted according to different settings of the product. For example, in an embodiment, the size of the connecting beam 20 is larger than the accommodating size of the connecting assembly 30, and the tightening of the connecting beam 20 by the connecting upper seat 31 and the connecting lower seat 32 needs to be realized by the locking piece 33, and the force application piece 3321 needs a larger locking moment; corresponding limiting structures can be arranged to prevent the force application member 3321 from being too tight; for example, in another embodiment, the dimension of the connecting beam 20 is smaller than or equal to the accommodating dimension of the connecting assembly 30, and the force application member 3321 requires a smaller locking moment; corresponding limiting structures may also be provided to prevent over-tightening of the force applying member 3321.
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. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
