Description

Technical Field

[0001] The utility model relates to the technical field of wall construction, in particular to a lifting device. Background Art

[0002] At present, large-sized ceramic tiles are commonly used for wall decoration of houses. Visually, the style is generous and gives people a sense of extension and openness. When large-sized ceramic tiles are placed on the wall, due to the large quality of the wall surface layer of the veneer tiles, a large shear stress is generated between the primer and the base layer. If the surface flatness deviation of the base layer is large, the base layer is improperly treated or the construction operation is improper, and the bonding strength between the layers is poor, the surface layer will produce hollows and easily fall off the surface. Therefore, during the pasting process of the tiles, it is advisable to fix them once and for all and not to move them, especially after the mortar absorbs water and then corrects the deviation and moves them, which is easy to cause hollows.

[0003] When pasting large-sized tiles on the wall, after pasting one layer of tiles, the top of the tiles should be kept straight, the top should be scraped flat, and the dividing strips should be placed before pasting the second layer of tiles. In order to ensure the pasting quality of the wall tiles, the horizontal elevation of the wall tiles needs to be aligned. The method used is: using laser leveling, adding wooden wedges and pads to the bottom of the wall tiles. However, in actual operation, it is necessary to repeatedly raise the height, which is easy to cause poor stability of the wall tiles, thereby affecting the quality of the wall tiles.

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] See also Figures 1 to 4 , the figure shows the preferred structure of the lifting device in this embodiment. As shown in the figure, the lifting device includes: a support device 1 and a lifting mechanism 2. Among them, the support device 1 is set on one side of the structure to be installed, and the lifting mechanism 2 is movably set on the support device 1, so that the lifting mechanism 2 can move relative to the support device 1. The lifting mechanism 2 is used to support the object 3 to be lifted. In this way, when the lifting mechanism 2 moves, it drives the object 3 to be lifted to move, so that the object 3 to be lifted can move relative to the support device 1. Specifically, the lifting mechanism 2 is along the height direction of the support device 1 ( Figure 1 If the lifting member 3 moves in the direction from top to bottom as shown in the figure, the lifting member 3 also moves in the height direction of the supporting device 1.

[0023] During specific implementation, the member 3 to be lifted may be a wall tile, and correspondingly, the structure to be installed is a wall structure.

[0024] It can be seen that in the present embodiment, the lifting mechanism 2 can be moved relative to the supporting device 1, driving the part to be lifted 3 to move relative to the supporting device 1, so that the part to be lifted 3 can be moved to the desired position. When the part to be lifted 3 is a wall tile, the wall tile can be adjusted to the desired elevation according to actual needs through the lifting of the lifting mechanism 2, thereby realizing the adjustment of the horizontal height difference of the upper installation of the wall tile. After the wall tile is lifted to the desired position, the wall tile can be fixed without adding wooden wedges or pads to repeatedly raise it, thereby improving the stability of the wall tile and thus ensuring the construction quality of the wall tile. In addition, the operation is simple, the construction efficiency is improved, and the problem of repeated raising of the wall tile for horizontal elevation alignment in the prior art is solved.

[0025] See also Figures 1 to 4 In the above embodiment, the lifting mechanism 2 includes: a supporting plate 21, a driving mechanism 22 and a backstop mechanism 23. The supporting plate 21 is movably disposed on the supporting device 1, and the supporting plate 21 is used to support the to-be-lifted member 3. Specifically, the supporting plate 21 is movably disposed on the supporting device 1 along the height direction of the supporting device 1.

[0026] The driving mechanism 22 is disposed on the supporting device 1 , and the driving mechanism 22 is connected to the supporting plate 21 . The driving mechanism 22 is used to drive the supporting plate 21 to move.

[0027] The anti-retraction mechanism 23 is movably arranged on the supporting device 1, and is used to prevent the support plate 21 from retreating. Specifically, when the support plate 21 drives the member to be lifted 3 to move, the anti-retraction mechanism 23 prevents the support plate 21 from retreating, which can ensure the stable movement of the support plate 21, avoid the unstable position of the support plate 21, ensure the stability of the member to be lifted 3 during the movement process and when it is parked at the required position, and effectively ensure the construction quality of the wall tiles when the member to be lifted 3 is a wall tile.

[0028] See also Figures 1 to 4 The driving mechanism 22 may include: a lifting shaft 221, a lifting plate 222, a first elastic member 223 and a pull structure. The lifting shaft 221 is provided on the support device 1, and the supporting plate 21 is movably provided on the lifting shaft 221. Specifically, the lifting shaft 221 is provided along the height direction of the support device 1, and the height direction of the lifting shaft 221 is consistent with the height direction of the support device 1. The supporting plate 21 is provided with an opening corresponding to the lifting shaft 221 to ensure that the supporting plate 21 can move freely along the lifting shaft 221.

[0029] The lifting plate 222 is provided with a through hole for the lifting shaft 221 to pass through, and the aperture of the through hole is slightly larger than the diameter of the lifting shaft 221 to ensure that the lifting plate 222 can move along the lifting shaft 221, and there is a preset tolerance between the aperture of the through hole and the diameter of the lifting shaft 221, and the preset tolerance can be determined according to actual conditions, and this embodiment does not impose any restrictions on this.

[0030] The first elastic member 223 is sleeved on the lifting shaft 221, and the first elastic member 223 is placed between the lifting plate 222 and the supporting plate 21. Specifically, the first elastic member 223 can be a spring.

[0031] The pull structure is connected to the supporting plate 21, and the pull structure is arranged on the first side of the lifting plate 222. The pull structure is used to push the first side of the lifting plate 222 to move downward, so that the lifting plate 222 interacts with the lifting shaft 221, thereby driving the supporting plate 21 to move upward. Specifically, the first side of the lifting plate 222 moves downward, and at this time, the lifting plate 222 is in an inclined state, so that the through hole is also in an inclined state, and the lifting plate 222 compresses the first elastic member 223 downward, so that the lifting plate 222 and the lifting shaft 221 act relative to each other, driving the supporting plate 21 to move upward, so that the member to be lifted 3 moves upward, and the member to be lifted 3 moves upward along the height direction of the support device 1.

[0032] The trigger structure includes: a trigger handle 224 and a hand-held handle 225. The hand-held handle 225 includes: a hand-held portion 2251 and a connecting portion 2252. The connecting portion 2252 is U-shaped. Specifically, the connecting portion 2252 includes: two side walls and a bottom wall sandwiched between the two side walls. The connecting portion 2252 has an open end and a closed end. The bottom wall forms the closed end, and the area between the ends of the two side walls away from the bottom wall is open to form the open end. The hand-held portion 2251 is in an inclined state. The hand-held portion 2251 is arranged on one side of the closed end of the connecting portion 2252, that is, the hand-held portion 2251 is arranged at the connection between one of the side walls and the bottom wall of the connecting portion 2252, and the hand-held portion 2251 is placed on the outside of the connecting portion 2252. There is an obtuse angle between the hand-held portion 2251 and the bottom wall of the connecting portion 2252, so that the hand-held portion 2251 is inclined upward away from the connecting portion 2252. Preferably, the connecting portion 2252 and the handle portion 2251 are integrally formed. The handle portion 2251 and the first side of the lifting plate 222 are disposed on the same side.

[0033] The open end of the connecting portion 2252 is connected to the supporting plate 21, and the connecting portion 2252 and the supporting plate 21 are surrounded by a containing frame. The closed end of the connecting portion 2252 is movably inserted into the lifting shaft 221. Specifically, the lifting shaft 221 is movably inserted into the closed end of the connecting portion 2252 after being inserted into the supporting plate 21, and the lifting shaft 221 is partially placed in the containing frame. In a specific implementation, the closed end of the connecting portion 2252 is provided with an opening, and the aperture of the opening is slightly larger than the outer diameter of the lifting shaft 221, so that the closed end of the connecting portion 2252 can move along the lifting shaft 221.

[0034] The lifting plate 222 is disposed inside the accommodating frame.

[0035] The pull handle 224 is rotatably connected to the side wall of the connecting portion 2252. Specifically, the pull handle 224 is placed below the hand-holding portion 2251. The pull handle 224 is rotatably connected to the side wall of the connecting portion 2252 near the hand-holding portion 2251, preferably through a rotating shaft. Of course, other rotating connection methods can also be used, and this embodiment does not impose any restrictions on this.

[0036] The first end of the pull handle 224 is placed in the accommodating frame, and the first end of the pull handle 224 is crimped to the first side of the lifting plate 222. The second end of the pull handle 224 is a free end and is placed outside the accommodating frame. At the same time, the second end of the pull handle 224 is placed below the hand-held portion 2251.

[0037] During specific implementation, in the initial state, the first elastic member 223 is in a certain compression state, and the first elastic member 223 pushes the lifting plate 222 to move toward the closed end of the accommodating frame, but the lifting plate 222 is restricted by the closed end of the accommodating frame. Since the first end of the pull handle 224 is crimped to the first side of the lifting plate 222, the pull handle 224 is in an inclined state driven by the lifting plate 222, and is inclined downward, so there is a certain gap between the pull handle 224 and the hand-held part 2251.

[0038] Preferably, two mounting plates 226 are protruded outward from the first side of the lifting plate 222, and the two mounting plates 226 are arranged in parallel, and there is a certain distance between the two mounting plates 226, and the distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. Each mounting plate 226 extends toward the trigger handle 224. A crimping shaft is arranged between the two mounting plates 226, and an anti-slip block 227 is arranged on each mounting plate 226, then there are two anti-slip blocks 227, and each anti-slip block 227 extends toward the closed end of the accommodating frame, and the first end of the trigger handle 224 is clamped between the two anti-slip blocks 227, and the first end of the trigger handle 224 is crimped onto the crimping shaft. Specifically, the distance between the two anti-slip blocks 227 matches the lateral dimension of the first end of the pull handle 224, and the two anti-slip blocks 227 limit the position of the first end of the pull handle 224, ensuring that the first end of the pull handle 224 is crimped on the crimping shaft. In this way, the first end of the pull handle 224 can press the first side of the lifting plate 222 downward, so that the first side of the lifting plate 222 moves downward.

[0039] In specific implementation, the driving mechanism 22 may further include: a bottom plate 4, the open end of the connecting portion 2252 is connected to the bottom plate 4, and the connecting portion 2252 and the bottom plate 4 are surrounded to form a containing frame. The bottom plate 4 is detachably connected to the supporting plate 21, preferably by bolts.

[0040] It can be seen that in this embodiment, the driving mechanism 22 has a simple structure and is easy to implement. The lever structure pushes the first side of the lifting plate 222 to move downward, so that the lifting plate 222 and the lifting shaft 221 act relative to each other, driving the supporting plate 21 to move upward, and the part 3 to be lifted follows the supporting plate 21 and also moves upward and is lifted, so that the part 3 to be lifted can be lifted to the desired height position, which is convenient for the installation of the part 3 to be lifted.

[0041] See also Figures 1 to 4 In the above embodiments, the backstop mechanism 23 includes: a backstop plate 231 in an inclined state, a second elastic member 232 and a stopper 233. The stopper 233 is arranged on a side where the closed end of the connecting portion 2252 is placed outside the accommodating frame, and the stopper 233 extends away from the closed end of the connecting portion 2252.

[0042] The backstop plate 231 is movably disposed on the lifting shaft 221. Specifically, an opening is provided in the middle of the backstop plate 231, and the diameter of the opening is slightly larger than the diameter of the lifting shaft 221, so that the backstop plate 231 can move along the lifting shaft 221. In addition, the first end of the backstop plate 231 is movably disposed on the limiting member 233, and the position of the second end of the backstop plate 231 is higher than the position of the first end.

[0043] The second elastic member 232 is sleeved on the lifting shaft 221, and the second elastic member 232 is placed between the backstop plate 231 and the closed end of the connecting portion 2252. The second elastic member 232 is in a compressed state to push the backstop plate 231 to move away from the closed end of the accommodating frame, but the first end of the backstop plate 231 is limited by the limiter 233. Under the elastic restoring force of the second elastic member 232, the second end of the backstop plate 231 is tilted upward to ensure that the backstop plate 231 remains in an inclined state. At this time, the opening on the backstop plate 231 is in an inclined state, and the backstop plate 231 interacts with the lifting shaft 221 to prevent the pull structure and the supporting plate 21 from retreating. Specifically, the second elastic member 232 can be a spring.

[0044] Preferably, a limiting portion 234 is provided at one end of the limiting member 233 away from the connecting portion 2252 .

[0045] The first end of the backstop plate 231 is provided with a groove recessed toward the second end, and the groove is movably arranged in the limiter 233, and the lateral dimension of the limiter 234 is greater than the lateral dimension of the limiter 233, and the lateral dimension of the limiter 234 is greater than the lateral dimension of the groove. Specifically, the limiter 234 and the limiter 233 are roughly T-shaped, and the backstop plate 231 can move along the limiter 233 through the groove, but the backstop plate 231 is limited by the limiter 234, and the second elastic member 232 is in a compressed state, and the second elastic member 232 pushes the backstop plate 231 to move toward the closed end away from the accommodating frame, but the backstop plate 231 is limited by the limiter 234, and the second end of the backstop plate 231 is a free end, so the backstop plate 231 remains in an inclined state.

[0046] In a specific implementation, the limiting portion 234 may be in a triangular shape, and the limiting portion 234 and the limiting member 233 form an arrow shape.

[0047] It can be seen that in the present embodiment, the structure of the anti-recognition mechanism 23 is simple and easy to implement, and the anti-recognition plate 231 is in an inclined state in a free state, that is, the anti-recognition state. The anti-recognition plate 231 applies an anti-recognition force to the driving mechanism 22 to prevent the support plate 21 from retreating. The anti-recognition plate 231 can be rotated to an unlocked state under the action of an external force, that is, the anti-recognition plate 231 is in a horizontal state, so that the support plate 21 can fall back downward to release the support plate 21 from supporting the lifting member 3.

[0048] See also Figures 1 to 4 In the above embodiment, the support device 1 includes: two support plates 11 and at least two support columns 12. The two support plates 11 are arranged in parallel, and each support column 12 is arranged between the two support plates 11 at intervals, so that each support column 12 supports the two support plates 11.

[0049] The lifting shaft 221 and each support column 12 are arranged in parallel, and the lifting shaft 221 is arranged between two support plates 11. Preferably, the lifting shaft 221 and each support column 12 are evenly distributed on the support plate 11.

[0050] In a specific implementation, there are two support columns 12 , and the lifting shaft 221 and the two support columns 12 are distributed on the support plate 11 in the shape of an equilateral triangle.

[0051] The supporting plate 21 is movably inserted into each supporting column 12 . Specifically, the supporting plate 21 is provided with an opening corresponding to each supporting column 12 , so that the supporting plate 21 can move along each supporting column 12 , and each supporting column 12 guides the movement of the supporting plate 21 .

[0052] The two ends of each support column 12 are detachably connected to the two support plates 11 in a one-to-one correspondence, and the two ends of the lifting shaft 221 are also detachably connected to the two support plates 11 in a one-to-one correspondence.

[0053] Preferably, the support plate 11 disposed below is provided with a first nut 13 at a position corresponding to the lifting shaft 221 and each support column 12 . Specifically, each first nut 13 is welded to the support plate 11 .

[0054] The upper support plate 11 is provided with a second nut 14 at a position corresponding to the lifting shaft 221 and each support column 12 .

[0055] Both ends of the lifting shaft 221 are provided with threads, and the two ends of the lifting shaft 221 are respectively screwed with the corresponding first nut 13 and the second nut 14. Both ends of each support column 12 are provided with threads, and the two ends of each support column 12 are respectively screwed with the corresponding first nut 13 and the second nut 14.

[0056] In a specific implementation, the support plate 11 placed above is provided with mounting holes corresponding to the lifting shaft 221 and each support column 12, and each second nut 14 is arranged on the upper plate surface of the support plate 11 and corresponds to each mounting hole one by one. Figure 1 The lower end shown in FIG. 1 is provided with a thread, and the second end ( Figure 1The upper end of each support column 12 is provided with a pad 15 near the end, and the second end of each support column 12 is provided with a thread, and the second end of each support column 12 is inserted into the corresponding mounting hole and then screwed with the second nut 14, and the pad 15 contacts the lower plate surface of the support plate 11 placed above. Figure 1 The lower end shown in FIG. 22 is provided with a thread, and the second end ( Figure 1 A pad 15 is also provided near the end portion (as shown in the upper end), and a thread is provided at the second end of the lifting shaft 221. The second end of the lifting shaft 221 is passed through the corresponding mounting hole and then screwed with the second nut 14. The pad 15 contacts the lower plate surface of the support plate 11 placed above.

[0057] In specific implementation, the two support plates 11 are both trapezoidal. In this embodiment, each support plate 11 can be a trapezoidal plate with a thickness of 10 mm.

[0058] In specific implementation, each support column 12 can be a round steel. In this embodiment, the diameter of the round steel is φ8mm.

[0059] It can be seen that in this embodiment, the structure of the support device 1 is simple and easy to implement, and the support device 1 can ensure the overall stability of the lifting device to avoid instability, and can also ensure the free lifting and lowering movement of the lifting mechanism 2. Each support column 12 in the support device 1 can guide the driving mechanism 22 to ensure that the driving mechanism 22 stays at any position, thereby ensuring the moving trajectory of the part to be lifted 3, and improving the firmness of the lifting device and the stability of the lifting mechanism 2.

[0060] Combination Figures 1 to 4The use process of the lifting device is introduced, and the lifting member 3 is a wall tile as an example: the lifting member 3 is placed on the supporting plate 21, and the operator holds the hand-held portion 2251 and the second end of the pull handle 224 tightly, so that the gap between the hand-held portion 2251 and the second end of the pull handle 224 becomes smaller, and the first end of the pull handle 224 presses downward on the first side of the lifting plate 222, so that the lifting plate 222 is in an inclined state, and the through hole on the lifting plate 222 is also in an inclined state. As the gap between the hand-held portion 2251 and the second end of the pull handle 224 gradually becomes smaller, the lifting plate 222 squeezes the first elastic member 223 downward, and because the through hole on the lifting plate 222 is in an inclined state, the lifting plate 222 interacts with the lifting shaft 221, and relying on the contact between the through hole and the lifting shaft 221, the pulling structure and the supporting plate 21 move upward as a whole, driving the lifting member 3 to move upward. After the second end of the pull handle 224 contacts the hand-held portion 2251, the second end of the pull handle 224 is released, and the gap between the hand-held portion 2251 and the second end of the pull handle 224 gradually increases. Under the elastic restoring force of the first elastic member 223, the lifting plate 222 moves upward, driving the first end of the pull handle 224 to move upward, so that the pull handle 224 returns to its original position.

[0061] During this lifting process, the second elastic member 232 pushes the backstop plate 231, the first end of the backstop plate 231 is limited by the limiting portion 234, the second end of the backstop plate 231 is a free end and its position is higher than the position of the first end, that is, the backstop plate 231 is in a backstop state, preventing the supporting plate 21 from retreating.

[0062] After the lever 224 returns to its original position, the second end of the lever 224 can be tightened and loosened again to lift the component 3 to be lifted multiple times until it reaches the desired height. When the component 3 to be lifted is a wall tile, the wall tile is lifted to the installation elevation through multiple lifting and then fixed.

[0063] After the part 3 to be lifted reaches the required height and is fixed, the operator applies force to the second end of the stop plate 231, that is, presses the second end of the stop plate 231 downward, so that the second elastic member 232 continues to be in a compressed state. When the stop plate 231 is pressed to a horizontal state, the stop plate 231 can move along the lifting shaft 221. At this time, the pull structure and the supporting plate 21 can move downward along the lifting shaft 221, and the supporting plate 21 is separated from the part 3 to be lifted, thereby releasing the support of the part 3 to be lifted.

[0064] In summary, in the present embodiment, the lifting mechanism 2 can move relative to the supporting device 1, driving the part to be lifted 3 to move relative to the supporting device 1, so that the part to be lifted 3 can be moved to the desired position, so that the part to be lifted 3 can be quickly and stably adjusted to the desired elevation. When the part to be lifted 3 is a wall tile, the wall tile can be lifted by the lifting mechanism 2 to quickly and stably adjust to the desired elevation according to actual needs, and the height difference of the upper installation level of the wall tile can also be adjusted. After the wall tile is lifted to the desired position, the wall tile can be fixed, thereby avoiding the wall tile from being affected by external factors and being displaced by gravity. There is no need to add a wedge iron to the lower mouth of the wall tile and repeatedly pad the height difference as in the prior art, thereby improving the stability of the wall tile, thereby ensuring the construction quality of the wall tile, and simple operation, thereby improving construction efficiency and reducing the labor intensity of personnel.
