All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. 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.

Referring to fig. 1a to 2d, the present application discloses a carrier lifting device, which includes a lifting column 11, a hoisting mechanism 111 installed at the top end of the lifting column 11, and a supporting mechanism 112 installed at the bottom of the lifting column 11;

hoisting machine constructs 111 and includes:

a lifting seat 1111 installed at the top end of the lifting column 11 and having a lifting chamber 1112 inside;

a hoisting fixed block 1113 accommodated in the hoisting chamber 1112 and connected to the hoisting mechanism 12 on the hoisting column 11;

the hoisting rotating assembly 1114 is used for limiting the relative positions of the hoisting seat 1111 and the hoisting fixed block 1113 in the axial direction of the hoisting column 11 and releasing the relative rotation between the hoisting seat 1111 and the hoisting fixed block 1113;

the support mechanism 112 includes:

a support seat 1121, one end of which abuts against the support surface and the other end of which is connected with the bottom end of the lifting column 11;

the rotation stop seat 1122 is disposed between the support seat 1121 and the bottom end of the lifting column 11, and is used for limiting the rotation between the lifting column 11 and the support seat 1121.

The lifting column 11 in this embodiment is installed through the supporting mechanism 112 at the bottom, and the hoisting mechanism 111 is used for connecting the lifting mechanism 12 and the lifting column 11.

The hoisting mechanism 111 realizes the motion release between the lifting mechanism 12 and the lifting column 11 through the hoisting rotating assembly 1114. The above-mentioned movement is embodied as a rotational movement of a part of the lifting mechanism 12 relative to the lifting column 11. The rotation may be accompanied by the lifting movement in the upward direction relative to the lifting column 11, for example, the screw 121 may drive the lifting mechanism 12 to rotate along with the screw 121 when the lifting column 11 goes upward or downward; the above-mentioned rotary motion may also be a sporadic motion when the lifting mechanism 12 moves upward relative to the lifting column 11, for example, a transmission structure such as a chain, a driving belt, a gear rack, etc. drives the lifting mechanism 12 to rotate along with the lifting column 11 in an upward or downward direction so as to adjust the direction of the load.

The support mechanism 112 can realize the axial support of the lifting column 11 and also realize the circumferential limit of the lifting column 11. When the lifting mechanism 12 moves relative to the lifter, referring to the above-mentioned manner of driving the lifting mechanism 12, the lifting column 11 may be subjected to a component of rotational force from the driving mechanism, thereby tending to move in its circumferential direction. The present embodiment achieves the positioning effect of the lifting column 11 through the rotation stopping seat 1122.

To sum up, the technical scheme disclosed in this application realizes the installation of lifting column 11 through hoisting machine 111 and supporting mechanism 112, and hoisting machine 111 can realize the motion of lifting mechanism 12 on lifting column 11 simultaneously, and overall structure is simple stable, has positive meaning to the miniaturization and the compact design of overall device.

The hoisting mechanism 111 and the support mechanism 112 will be explained in detail separately below. Referring to an embodiment, the hoist rotation assembly 1114 includes:

a rotation base 1115 accommodated in the hoisting chamber 1112, one end of which abuts against the hoisting base 1111 and the other end of which is open to form a rotation chamber 1116;

and a rotating member 1117 received in the rotating chamber 1116 and configured to release the relative rotation between the lifting seat 1111 and the lifting fixing block 1113.

Swivel 1115 can provide a constraint for rotation of swivel 1117 to avoid component displacement and positioning failures during rotation. The rotating member 1117 is the actual component that releases the rotational motion. The rotating member 1117 may be a different member depending on the rotational stroke in a specific product. For example, when the driving member of the lifting mechanism 12 is the screw 121, the rotating member 1117 may be a bearing, a bush, or the like that can rotate circumferentially; for example, when the driving member of the lifting mechanism 12 is a chain, a driving belt, a rack and pinion, etc., the rotating member 1117 may be in the form of an elastic member such as a rubber seat, and the rotating member 1117 under this arrangement can release the rotation stroke by deforming itself.

In the assembly of the lifting seat 1111 and the rotation seat 1115, referring to an embodiment, the lifting chamber 1112 is stepped in cross section, and the lifting seat 1111 and the rotation seat 1115 are abutted against the first step 113 passing through in the axial direction of the lifting column 11.

The lifting saddle 1111 is required to realize positioning of the swivel 1115, particularly in the axial direction of the lifting column 11. In the present embodiment, the above-described positioning effect is achieved by the first step 113. Specifically, the shape of the lifting seat 1111 is complementary to the shape of the rotating seat 1115, and both are stepped, and the two are matched with each other through the first steps 113 corresponding to each other. Besides the axial limit, the matching of the outer edge of the first step 113 can also realize the positioning of the hoisting seat 1111 and the rotating seat 1115 in the radial direction of the lifting column 11, thereby improving the stability of the assembly.

Similarly, the axial and radial positioning between the lifting seat 1111 and the lifting column 11 is also required. Referring to an embodiment, the lifting column 11 is cylindrical, at least a portion of the lifting seat 1111 is inserted into the top end of the lifting column 11, and the lifting seat 1111 abuts against the second step 114, through which the lifting column 11 passes in the axial direction.

The positioning effect of the second step 114 is similar to the principle of the first step 113, and will not be described herein. But it is different that the lifting seat 1111 may be selected to receive a part of the lifting column 11 or a part of the lifting column 11. The positioning and assembling effects of the second step 114 are not different greatly in the matching, and the second step can be arranged as required in an actual product.

In the engagement between the hoisting fixture block 1113 and the rotating member 1117, referring to an embodiment, the hoisting fixture block 1113 is pressed against the rotating member 1117 directly or through an intermediate member.

The hoisting fixed block 1113 can realize the connection with a certain part of the lifting mechanism 12, such as the screw 121 in fig. 2 a. The hoisting fixing block 1113 and the rotating piece 1117 are pressed against each other to realize hoisting. In a specific product, a certain part of the fixed hoisting block 1113 and the lifting mechanism 12 can be formed in various forms such as welding, screwing, bonding and integral forming, and the corresponding fixed hoisting block 1113 and the rotating part 1117 can also be directly pressed against each other or indirectly pressed against each other through an intermediate part.

As will be appreciated from the foregoing, the hoist mechanism 111 is located within the hoist chamber 1112 and provides for relative movement. In an embodiment, a lifting cover 1118 is disposed on a side of the lifting base 1111 facing away from the lifting column 11, and the lifting cover 1118 is used to cooperate with the lifting base 1111 to close the lifting chamber 1112.

After the hoisting cover 1118 closes the hoisting chamber 1112, the components in the hoisting chamber 1112 can be isolated from the external environment, so that the stability of the hoisting mechanism 111 is improved. In the use of the product, the maintenance cycle of the lubricating medium and other media which are easily influenced by the external environment in the hoisting mechanism 111 can be prolonged. In the embodiment shown in the drawings, the hoisting cover 1118 is detachably mounted on the top end of the hoisting base 1111 through bolts.

In the configuration of the supporting mechanism 112, referring to an embodiment, the lifting column 11 is cylindrical, the supporting seat 1121 accommodates at least a portion of the bottom end of the lifting column 11, and at least a portion of the rotation stopping seat 1122 is located between the bottom end of the lifting column 11 and the gap between the supporting seat 1121.

The supporting seat 1121 can be disposed inside the supporting column or wrapped outside the supporting column, and the positioning column is axially and radially fixed through the positioning relationship between the supporting seat and the supporting column. The rotation stopper 1122 is located between the bottom end of the lifting column 11 and the gap between the supporting seat 1121 to limit the relative rotation between the lifting column 11 and the supporting seat 1121, so as to provide a better positioning effect for the lifting column 11 and avoid unnecessary wear between the components.

In a specific configuration of the rotation stopping seat 1122, referring to an embodiment, the rotation stopping seat 1122 includes:

a connecting cylinder 1123 sleeved between the gap between the bottom end of the lifting column 11 and the supporting seat 1121;

the rotation stopping portion 1124 is outwardly turned from the top edge of the connection cylinder 1123 and extends radially, and the rotation stopping portion 1124 cooperates with the support seat 1121 to limit the rotation of the connection cylinder 1123 relative to the support seat 1121.

The bottom ends of the communicating cylinder body and the lifting column 11 can be in interference fit, and are limited mutually through friction force, and corresponding rotation stopping structures can be arranged, such as key grooves, tooth surfaces and the like. The rotation stopping portion 1124 extends in the radial direction of the supporting column to increase the limiting moment, and the engagement between the rotation stopping portion 1124 and the supporting seat 1121 may be direct engagement or may be engaged by an independent positioning member 1126 as shown in the drawings. In one embodiment, the rotation stopper 1124 is ring-shaped, the inner edge of the ring is connected to the top edge of the connecting cylinder 1123, the outer edge of the ring is provided with positioning teeth 1125, and the supporting seat 1121 is provided with positioning members 1126 engaged with the positioning teeth 1125. The positioning member 1126 and the positioning teeth 1125 engage until the swivel base 1122 provides a stable positioning effect.

The rotation stopper 1122 can also have an axial position-limiting effect, in addition to a circumferential position-limiting effect on the lifting column 11. Referring to one embodiment, the rotation stop 1122 further includes a support skirt 1127, the support skirt 1127 extending radially from the inner sidewall or bottom edge of the connection cylinder 1123 and abutting the bottom edge of the lifting column 11.

The support skirt 1127 may be a separate component from the anti-rotation mount 1122 or may be formed from an extension of the material of the connection cylinder 1123 itself as shown in the drawings. The supporting side edge 1127 can provide axial limit for the lifting column 11 and simultaneously can reduce the fit clearance between the rotation stop seat 1122 and the lifting column 11, thereby providing a better mechanism basis for circumferential fit of the two.

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.
