The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can be implemented or applied by other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than being drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed arbitrarily, and the layout of the components may be more complicated.

Embodiments of the present invention are described below with reference to the drawings. In the following drawings, like reference numerals are used for like parts. Although the embodiments are described using terms indicating directions such as "front", "rear", "upper", "lower", "left", "right", and the like in the present invention, these terms are used herein for convenience of description only and are determined based on exemplary orientations shown in the drawings. Because the disclosed embodiments may be arranged in different orientations, these directional terms are used for descriptive purposes and are not to be construed as limiting.

For example, the term "first support" does not itself imply the presence of "second support", nor does the term "second support" itself imply the presence of "first support".

The utility model discloses a hoist and mount subassembly is arranged in setting up the floor in the building for hoist and mount object. For example, a building includes multiple floors (e.g., 20 floors), and when it is desired to transport an object from outside the building (e.g., 1 floor) to 18 floors, an operator can place the hoist assembly in 18 floors of the building and then hoist the object from 1 floor to 18 floors via the hoist assembly.

As shown in fig. 1-4, the hoisting assembly of the present invention comprises a base 10 and a hoisting device 20. Wherein the hoisting device 20 is used for hoisting an object. The base 10 is intended to be placed in a building and to provide support for the lifting device 20. The lifting device 20 is movable relative to the base 10 and has a first operating position (as shown in figures 1-2) and a second operating position (as shown in figures 3-4).

As shown in fig. 1 to 4, the base 10 of the present invention includes a base main body 101, a pair of first supporting members 111, a pair of second supporting members 112, and a pair of third supporting members 113. The base main body 101 is a substantially rectangular frame having a thickness. Specifically, the base main body 101 includes a base first rod 102, a base second rod 103, a base third rod 104, and a base fourth rod 105, which are sequentially enclosed. Wherein the base first bar 102 is disposed at the front side and the base third bar 104 is disposed at the rear side. The base first rod 102 and the base third rod 104 extend in the longitudinal direction of the base body 101. A pair of first supports 111 are provided on the base first bar 102 and the base third bar 104, respectively, and a pair of second supports 112 are provided on the base first bar 102 and the base third bar 104, respectively. A pair of first supports 111 is disposed near the left side, and a pair of second supports 112 is disposed near the right side. The pair of third supporting members 113 is transversely disposed between the first supporting members 111 and the second supporting members 112, thereby enhancing the stability of the pair of first supporting members 111 and the pair of second supporting members 112.

As shown in fig. 1-4, a base moving mechanism is disposed on the base 10 for cooperating with the lifting device moving mechanism on the lifting device 20, so as to move the lifting device 20 relative to the base 10. In particular, the lifting assembly has a length direction, along which the lifting device 20 is movable relative to the base 10. More specifically, the base moving mechanism includes a pair of guide rails 121. One of the guide rails 121 is disposed at a front side of the base first bar 102, and the other guide rail 121 is disposed at a rear side of the base third bar 104. Further, the guide rail 121 has an opening toward the left side.

As shown in fig. 1-4, the lifting device 20 includes a frame 201 for cooperating with the base 10. The frame 201 is substantially a rectangular frame having a thickness. Specifically, the frame 201 includes a frame first rod 202, a frame second rod 203, a frame third rod 204, and a frame fourth rod 205, which are sequentially enclosed. Wherein the rack first bar 202 is disposed at the front side and the rack third bar 204 is disposed at the rear side. The extension direction of the rack first bar 202 and the rack third bar 204 is the length direction of the rack 201. The width of the frame 201 is slightly smaller than the width of the base so that the frame first bar 202 and the frame third bar 204 can be received between the base first bar 102 and the base third bar 104. The lower portion of the frame 201 is also provided with a generally U-shaped support bar 216 for mounting a power mechanism.

As shown in fig. 1 to 4, the frame 201 is provided with a lifting device moving mechanism for cooperating with the base moving mechanism on the base 10, so as to realize the movement of the lifting device 20 relative to the base 10. Specifically, the hoist moving mechanism includes a pair of first wheels 206 and a pair of second wheels 207. A pair of first wheels 206 are respectively disposed at the front and rear sides of the frame first bar 202, a pair of second wheels 207 are respectively disposed at the front and rear sides of the frame first bar 202, and the pair of first wheels 206 are disposed at the middle of the frame 201 and the pair of second wheels 207 are disposed at the right portion of the frame 201. The first and

second wheels

206 and 207 can enter the guide rail 121 from the opening, be accommodated in the guide rail 121, and move in the length direction of the guide rail 121.

In addition, the hoisting assembly further comprises a blocking device. The blocking device is detachably connected to the base 10 so as to prevent the housing 201 from falling off the base 10 when moving relative to the base 10. In the present invention, the blocking means comprises a pair of blocks 51. The pair of blocks 51 can be respectively received in the pair of guide rails 121 and disposed at the opening so as to close the opening to prevent the first and

second wheels

206 and 207 received in the guide rails 121 from coming out of the guide rails 121. When the pair of first wheels 206 and the pair of second wheels 207 enter the guide rails 121, the pair of blocks 51 are respectively placed at the openings of the pair of guide rails 121 and are connected to the base 10 by the connectors. As an example, the connecting members are screws, and the base 10 is provided with corresponding holes. In other embodiments, the blocking device may be a pin or the like.

It will be appreciated that although a blocking device is provided in the present invention, in other embodiments, a pair of rails 121 may have an upward opening so that the first and

second wheels

206, 207 can be received in the rails 121 and prevent the frame 201 from falling out of the base 10 when the frame 201 moves relative to the base 10.

Thereby, the hoist 20 can move in the lengthwise direction with respect to the base 10. The lifting device 20 has a first operating position (as shown in fig. 1-2) and a second operating position (as shown in fig. 3-4) and is movable between the first operating position and the second operating position. When the hoist 20 is in the first operating position, the first wheel 206 is substantially in the middle of the rail 121 and the second wheel 207 is substantially at the right end of the rail 121. In the length direction, the frame 201 substantially coincides with the base 10, such that the lifting assembly has a first length. When the hoist 20 is in the second operating position, the first wheel 206 is substantially at the left end of the rail 121 and the second wheel 207 is substantially in the middle of the rail 121. In the length direction, the left end of the frame 201 exceeds the left end of the base 10, so that the hoisting assembly has a second length. Wherein the second length is greater than the first length.

It is understood that although the first wheel 206 is disposed substantially in the middle of the frame 201 and the second wheel 207 is disposed substantially in the right of the frame 201, in other embodiments, the distance between the first wheel 206 and the second wheel 207 may be arranged as desired, only if the second length is greater than the first length.

Other components of the hoist device 20 are briefly described below with reference to fig. 1-6. As shown in fig. 1-6, the lifting device further comprises a lifting mechanism, a power mechanism and a hook assembly. Wherein the lifting mechanism is movable relative to the frame 201 and has a standby position and a hoisting position. The power mechanism is arranged on the frame 201 and the lifting mechanism and is matched with the lifting mechanism to lift or lower the hook component. The lifting hook component is used for hooking an object to be lifted.

As shown in fig. 5-6, the lifting mechanism of the lifting device is rotatably connected to the frame 201. Specifically, the lifting mechanism includes a first lifting mechanism body 211, a second lifting mechanism body 212, and a connecting mechanism 213. In the present invention, the connecting mechanism 213 is a hinge. One end of the connection mechanism 213 is connected to the first lifting mechanism body 211, and the other end of the connection mechanism 213 is connected to the second lifting mechanism body 212, so that the first lifting mechanism body 211 can rotate relative to the second lifting mechanism body 212.

As shown in fig. 1 to 6, the first lifting mechanism main body 211 is a substantially rectangular frame having a thickness (i.e., formed of a front frame, a left frame, a rear frame, and a right frame connected in this order). The left end of the first lifting mechanism main body 211 is connected to the connection mechanism 213. A pair of first guide grooves 214 are provided on the outer sides of the front frame and the rear frame of the first lifting mechanism main body 211, and the first guide grooves 214 extend in the longitudinal direction of the first lifting mechanism main body 211. The first guide groove 214 is configured to receive the first pulley 92 and the second pulley 94 of the connecting slide assembly 90, so that the first lifting mechanism main body 211 can translate relative to the first pulley 92 and the second pulley 94 of the connecting slide assembly 90.

As shown in fig. 1 to 6, the second lifting mechanism main body 212 includes two rods (i.e., a front rod and a rear rod) extending in parallel to the frame first rod 202 and the frame third rod 204 of the frame 201. The front lever of the second lifting mechanism main body 212 has one end rotatably connected to the frame first lever 202 and the other end connected to the connecting mechanism 213. The rear lever of the second lifting mechanism main body 212 has one end rotatably connected to the frame third lever 204 and the other end connected to the connecting mechanism 213. Thus, the second lifting mechanism body 212 is rotatably connected to the frame 201. Further, the connecting mechanism 213 is connected to the first lifting mechanism main body 211 while being connected to the second lifting mechanism main body 212, so that the first lifting mechanism main body 211 can be rotated with respect to the second lifting mechanism main body 212.

As shown in fig. 1-6, a pair of connecting slide assemblies 90 are disposed at the right end of the frame 201. For each connecting slide assembly 90, it includes a base plate 91 and a set of pulleys disposed on base plate 91. The pulley block includes a first pulley 92 and a second pulley 94. The base plate 91 is rotatably connected to the frame 201. Specifically, the right end of the rack first bar 202 and the right end of the rack third bar 204 are provided with rack through holes 107. Each of the two substrates 91 is provided with a substrate through-hole 93. The frame through-holes 107 of the frame first bar 202 are aligned with the substrate through-holes 93 of one of the substrates 91, and a connector (not shown) is received in the frame through-holes 107 of the frame first bar 202 and the substrate through-holes 93 of the substrate 91, so that the substrate 91 is rotatably connected to the frame 201. The frame through hole 107 and the substrate through hole 93 on the substrate 91 and the connection member define a rotation axis so that the substrate 91 rotates about the rotation axis with respect to the frame 201. The first pulley 92 and the second pulley 94 are disposed on the substrate 91, and are disposed on the same side of the substrate 91. The first pulley is rotatable about a first pulley axis and the second pulley 94 is rotatable about a second pulley axis. The first and second pulley axes are parallel to the frame fourth bar 205 of the frame 201, and the rotation axis, the first pulley axis and the second pulley axis are not coaxially arranged. The first pulley 92 and the second pulley 94 are accommodated in first guide grooves of the front frame and the rear frame of the first lifting mechanism main body 211. When the base plate 91 rotates about the rotation axis with respect to the frame 201, the first pulley 92 and the second pulley 94 also rotate about the rotation axis together, and the first lifting mechanism body 211 can translate with respect to the first pulley 92 and the second pulley 94. A pair of connecting slide assemblies 90 are symmetrically arranged on the frame 201 in front and back directions, so the detailed structure and the matching relationship with other components of the other connecting slide assembly 90 are not described in detail.

The lifting mechanism thus has a standby position (as shown in fig. 1-4) and a hoisting position (as shown in fig. 6) relative to the frame 201. When the lift mechanism is in the standby position, the frame 201, the first lift mechanism body 211, the second lift mechanism body 212, and the base body 101 are disposed substantially in parallel. When the lifting mechanism is in the lifting position, the first lifting mechanism body 211 is substantially perpendicular to the frame 201, and the second lifting mechanism body 212 is disposed obliquely to the frame 201 and the first lifting mechanism body 211.

It should be noted that when the lifting mechanism is in the standby position, the upper surface of the first lifting mechanism main body 211 is flush with the upper surface of the base main body 101 regardless of whether the lifting device 20 is located in the first operating position or the second operating position.

As shown in fig. 1 to 6, the lifting device further includes a pair of elastic members 80 for connecting the support rod 216 and the second lifting mechanism body 212 on the frame 201 and providing a force for rotating the first lifting mechanism body 211 and the second lifting mechanism body 212 with respect to the frame 201. Specifically, one end of each of the pair of elastic members 80 is connected to the support rod 216 on the frame 201, and the other end of each of the pair of elastic members 80 is connected to the front rod and the rear rod of the second lifting mechanism main body 212, respectively. When the first lifting mechanism main body 211 is located at the standby position, the pair of elastic members 80 are in a compressed state. The compressed pair of elastic members 80 applies a force to the second lifting mechanism body 212, so that the second lifting mechanism body 212 rotates clockwise with respect to the frame 201. Since the left ends of the first lifting mechanism body 211 and the second lifting mechanism body 212 are connected to each other by the connecting mechanism 213, the first lifting mechanism body 211 can be translated with respect to the connecting slide assembly 90, and the connecting slide assembly 90 can be rotated with respect to the frame 201, so that when the second lifting mechanism body 212 is rotated clockwise with respect to the frame 201, the first lifting mechanism body 211 is rotated with respect to the frame 201 while moving downward with respect to the frame 201.

In the present invention, the elastic member 80 is a telescopic rod having a spring. Those skilled in the art will appreciate that the resilient member 80 may be other resilient members.

As shown in fig. 1-6, the hook assembly is rotatably coupled to the first lifting mechanism body 211. Specifically, a pair of rings 416 (only one ring 416 is shown in fig. 1-5 for clarity) is provided on the left frame of the first lifting mechanism body 211. The hook assembly includes a hook base 411, a pair of hooks 412 and a pair of jaws 418. The hook base 411 is a sheet material having a thickness, including a left edge, a right edge, a front edge, and a back edge. A pair of lifting claws 418 (only one ring 416 is shown in fig. 1-5 for clarity of illustration) are provided at the left edge of the hook base 411. The pair of lifting claws 418 can respectively grip the pair of rings 416 on the first lifting mechanism body 211 so that the hook assembly is rotatably connected with the first lifting mechanism body 211. First and

second hook wheels

413 and 415 are provided at front and rear ends of the hook base 411 near the left edge, respectively. A pair of hooks 412 are provided at front and rear ends of the hook base 411 near the right edge for hooking an object to be hung. It should be noted that the number of hooks 412 in the hook assembly may be any number.

As shown in fig. 1-6, the power mechanism of the lifting device comprises a power device 301, a rope 302 and a pair of rope fixing wheels 303. Wherein, the power device 301 is arranged on the support rod 216 of the frame 201 and is used for pulling or releasing the rope 302. Specifically, the power unit 301 is a motor (not shown) capable of bidirectional rotation. The motor is able to release the cable 302 when the motor is rotating in the forward direction. When the motor is rotating in the reverse direction, the motor is able to tighten the cable 302. A pair of rope fixing pulleys 303 are provided at the left ends of the first lifting mechanism body 211, respectively, and are spaced apart from each other in the front-rear direction. One end of the rope 302 is connected to a motor in the power unit 301 on the frame 201. The other end of the rope 302 is connected to the power unit 301 after passing around the rope fixing pulley 303 on the front side, the second hook pulley 415, and the rope fixing pulley 303 on the rear side. Here, the rope 302 can generate a force to the first lifting mechanism main body 211 by passing around the pair of rope fixing wheels 303 to overcome the force generated by the pair of elastic members 80 in a compressed state, so that the first lifting mechanism main body 211 is held at the standby position.

The working principle of the hoist assembly is described below with reference to fig. 1-8:

in fig. 7-8, the upper floor 61 and the lower floor 62 of the floor are shown, and in which the scaffold 63 is also shown. And a glass assembly 64 is used as an example of the object to be hoisted. Firstly, the person of hoisting can be with the earlier the utility model discloses a hoist and mount subassembly transports the floor (for example, the third floor) of treating the hoist and mount. The second support 112 is then supported on the scaffold 63 and the first support 111 is supported on the lower floor 62. The lifting device 20 is then moved to the first operating position. The power unit 301 is then activated, as shown in fig. 5-6, causing the motor to rotate in a forward direction to release the cord 302. With the gradual release of the rope 302, the rope 302 no longer applies a leftward force to the first lifting mechanism body 211 via the pair of rope fixing pulleys 303. The pair of elastic members 80 in the compressed state applies a force to the left end of the second lifting mechanism body 212 parallel to the frame 201 to help the lifting mechanism rotate from the standby position (shown in fig. 1) to the lifting position (shown in fig. 6). Specifically, the pair of elastic members 80 in the compressed state applies an upward force to the left end of the second lifting mechanism body 212, so that the second lifting mechanism body 212 rotates clockwise with respect to the frame 201 to tilt with respect to the frame body 101. Since the left end of the second lifting mechanism body 212 and the left end of the first lifting mechanism body 211 are rotatably connected to each other by the connecting mechanism 213, when the second lifting mechanism body 212 is rotated clockwise, the first lifting mechanism body 211 is also rotated clockwise. In addition, since the right end of the first lifting mechanism main body 211 is rotatably connected to the frame main body 101 through the connecting slide assembly 90, the first lifting mechanism main body 211 can translate relative to the first pulley 92 and the second pulley 94 in the connecting slide assembly 90 during rotation relative to the frame main body 101. In other words, when the second lifting mechanism body 212 is rotated clockwise, the right end of the first lifting mechanism body 211 is also rotated clockwise while being translated downward away from the connecting slide assembly 90. Thereby, the lifting mechanism is moved to the hoisting position.

Release of cord 302 is then continued until a worker located at the bottom floor can hang glass subassembly 64 from hook 412. After the glass assembly 64 is hung on the hook 412, the power unit 301 is again activated and the motor is reversed, thereby tightening the cord 302. The cable 302 will move the glass assembly 64 upward until the glass assembly 64 is approximately level with the floor to be hoisted (e.g., third floor). Then, as the cord 302 is tightened, the glass assembly 64 is moved from the hoist position to the standby position by the hoist mechanism at the hoist position. The process of the lifting mechanism driving the glass assembly 64 to move from the hoisting position to the standby position is opposite to the process of the lifting mechanism moving from the standby position to the hoisting position, and the description is omitted here. The hoist may then translate the hoist 20 from the first operating position to the second operating position (as shown in fig. 8). Thus, the glass assembly 64 is hoisted to the floor to be hoisted, and since the upper surface of the first lifting mechanism body 211 is flush with the upper surface of the base body 101, the glass assembly 64 is fully carried by the hoisting mechanism.

It should be noted that although the present invention shows an embodiment in which the second support member 112 is supported on the scaffold 63 and the first support member 111 is supported on the lower floor 62, it will be understood by those skilled in the art that the first support member 111 and the second support member 112 may be supported on the lower floor 62 together.

In the prior art, although the first lifting mechanism body of the hoisting assembly can rotate relative to the base, because the length of the first lifting mechanism body is limited, an object with a large volume cannot be completely borne on the first lifting mechanism body, and the object is damaged.

The utility model discloses a hoist and mount subassembly has hoist device 20 and base 10 that can relative movement to can also carry out effectual support to the object when realizing the hoist and mount function, and can increase the degree of depth that the object got into the building, thereby avoid the object to damage.
