A vertical building material transport apparatus 100 according to an embodiment of the present invention is described with reference to fig. 1-5.

According to an embodiment of the present invention, a vertical building material transport device 100, as shown in fig. 1 to 4, the vertical building material transport device 100 includes: the device comprises a body 1, a conveying body 2, a conveying driving assembly 3, an upper clamping assembly 4 and a lower clamping assembly 5. As shown in fig. 1 and 3, the body 1 is adapted to be provided at a transfer port 210 of a floor slab 200. Here, the delivery port 210 is a through hole penetrating vertically and provided at a certain position on the floor 200, and the building material 300 at the lower layer is transported to the upper layer through the delivery port 210, or the building material 300 at the upper layer is transported to the lower layer through the delivery port 210. As shown in fig. 1 and 5, the transporting body 2 is provided on the body 1 to be movable up and down, and the transporting body 2 is adapted to extend from the transfer port 210 to below the floor 200 at least in part when it is lowermost. The conveying driving assembly 3 is used for driving the conveying body 2 to move up and down. As shown in fig. 1 and 4, the upper clamping assembly 4 is provided on the body 1, and the upper clamping assembly 4 is adapted to press against the upper surface of the floor 200. As shown in fig. 4, the lower card assembly 5 is provided on the body 1, a portion of the lower card assembly 5 is adapted to protrude downward from the transfer opening 210, and the lower card assembly 5 includes a pressing portion 52 pressed against the lower surface of the floor 200.

It can be understood that, as shown in fig. 1, during the vertical transportation of the building material 300 in the lower layer through the transfer opening 210, the conveyor 2 may extend from the transfer opening 210 to the lower floor, so that the building material 300 may be mounted on the conveyor 2, and as shown in fig. 5, the building material 300 may follow the conveyor 2 to move upward relative to the body 1 under the driving of the conveying driving assembly 3, so that the building material 300 may be transported from the lower floor to the upper floor. Of course, the building material 300 on the upper floor can be transported downward through the delivery opening 210, and at this time, a part of the conveyor 2 still can extend from the delivery opening 210 to the lower part of the floor 200 at the lowest part, and the building material 300 is fixed on the conveyor 2, and under the driving of the conveying driving assembly 3, the building material 300 can be transported downward along with the conveyor 2, so that the building material 300 can be transported from the upper floor to the lower floor. That is, the conveying driving assembly 3 drives the building material 300 to be transported across layers without being transported by workers, so that the labor intensity of the workers is reduced, the construction efficiency is improved, the safety of constructors is improved, and casualties caused by the fact that the building materials such as aluminum molds topple over due to the fact that the workers are not concentrated or lack of physical strength is reduced as much as possible.

In addition, in the vertical transportation process of the building materials such as the aluminum mold, the impact force generated by the building material 300 risks to push down the machine, and poses a threat to the personal safety and the property safety. To solve the problem, as shown in fig. 4, the present invention provides an upper clamping assembly 4 and a lower clamping assembly 5, wherein a portion of the lower clamping assembly 5 can extend downward from the conveying opening 210, the pressing portion 52 presses against the lower surface of the floor 200, and the upper clamping assembly 4 presses against the upper surface of the floor 200, so that the fixing and limiting effects can be exerted on the body 1, the vertical conveying device 100 for building materials can be stably fixed at the conveying opening 210, the situations of shaking, vertical movement, even overturning and the like of the vertical conveying device 100 for building materials can be effectively reduced, and the safety of field construction can be further improved.

According to the building material vertical conveying device 100 provided by the embodiment of the invention, the conveying body 2 is driven by the conveying driving component 3 to move up and down relative to the body 1, so that the building material 300 can move up and down along with the conveying body 2, the manual conveying and carrying is reduced, the labor intensity of workers is reduced, the construction efficiency is improved, the safety of constructors is improved, and the casualties caused by the fact that aluminum molds topple over due to the fact that the attention of the workers is not concentrated or the physical strength is insufficient are reduced as far as possible. In addition, the upper clamping assembly 4 and the pressing part 52 are respectively pressed against the upper surface and the lower surface of the floor slab 200, so that the fixing and limiting effects on the body 1 can be achieved, the building material vertical conveying device 100 is stably fixed at the conveying opening 210, and the site construction safety is further improved.

In some embodiments, as shown in fig. 1 and 2, the transport drive assembly 3 comprises: a conveying motor 31, a conveying rack 32 and a conveying gear 33. The conveying motor 31 is arranged on the body 1, the conveying rack 32 is vertically arranged on the conveying body 2, and the conveying gear 33 is connected with the conveying motor 31 and meshed with the conveying rack 32. It can be understood that, under the driving of the conveying motor 31, the conveying gear 33 can make a rotational motion, and the conveying rack 32 engaged with the conveying gear 33 can convert the rotational motion into a moving motion, that is, the conveying rack 32 can move up and down, so that the conveying gear 33 can drive the conveying body 2 to move up and down. The conveying driving assembly 3 adopts the driving structure, so that the number of parts is small, the structure is compact, the simplified design of the building material vertical conveying device 100 is facilitated, the driving structure is high in stability, and the transmission is more reliable.

Of course, in other embodiments of the present invention, the conveying driving assembly 3 may also adopt other structures, such as using a chain transmission mechanism, or directly adopting a linear motor as the conveying motor 31, etc.

In some embodiments, as shown in fig. 2, the upper clamping assembly 4 includes a plurality of length-adjustable feet 41, and the feet 41 are respectively disposed at the corners of the body 1. Thus, the plurality of feet 41 can support the body 1 together, and the working stability of the body 1 is improved. In addition, the plurality of feet 41 can also improve the fatigue resistance life of the feet 41, that is, the impact force generated by the building material 300 can be distributed on each foot 41, and the impact force received by a single foot 41 is reduced, so that the fatigue resistance of the foot 41 is improved, and the service life of the foot 41 is further prolonged.

In addition, if there is a certain height of the upper surface of the floor slab 200, the gap between the footing 41 and the upper surface of the floor slab 200 may cause the vertical transportation device 100 to be unstably fixed on the upper surface of the floor slab 200. The body 1 is provided with the footing 414 capable of moving up and down, and the length of the footing 41 can be adjusted to enable the footing 41 to be abutted against the upper surface of the floor slab 200, so that the stability of the body 1 is improved, and the working stability of the building material vertical transportation device 100 is further improved.

In some embodiments, as shown in fig. 2, the height-adjusting nut 11 is disposed on the body 1, and the footing 41 includes: the adjustable rod 411, the rotary table 412 and the chassis 413, the adjustable rod 411 is provided with an external thread and is matched on the height-adjusting nut 11, and the rotary table 412 and the chassis 413 are respectively arranged at the upper end and the lower end of the adjustable rod 411. It can be understood that by rotating the dial 412, the adjusting rod 411 can be rotated, and the adjusting rod 411 can convert the rotation motion into up and down movement, thereby changing the distance between the height-adjusting nut 11 and the chassis 413.

The matching of the height-adjusting nut 11 and the adjusting rod 411 is equivalent to a screw structure, in this way, the chassis 413 is driven to move, the rotating motion form is converted into the moving motion form, and the footing 41 converts a small rotating force into a large pressing force, so that the chassis 413 can support the body 1 conveniently.

In some embodiments, as shown in FIG. 4, the lower card assembly 5 includes: a connecting plate 51, a pressing portion 52 and a driving member 53. A connecting plate 51 is provided on the body 1 to be movable up and down, and a pressing portion 52 is provided at the bottom of the connecting plate 51. The driving member 53 is connected to the connecting plate 51 to drive the connecting plate 51 to move up and down. That is, the driving member 53 can drive the connecting plate 51 to move up and down, and the pressing portion 52 provided at the bottom of the connecting plate 51 can move up and down along with the connecting plate 51. Thus, when the vertical building material conveying device 100 is suitable for the arrangement of the conveying opening 210, the position of the pressing part 52 can be adjusted up and down so that the pressing part 52 is pressed against the lower surface of the floor slab 200.

The connection plate 51 moves up and down to drive the pressing part 52 to move up and down, and the operation is simple when the pressing part 52 is adjusted. And because the compressing part 52 can move up and down, the lower clamping component 5 can be repeatedly adjusted and then compressed, which is beneficial to keeping the stability of the building material vertical transportation device 100 when in long-term use. The transfer of the vertical building material transport device 100 from one transport opening 210 to another transport opening 210 is also very easy to accomplish. The driving member 53 may be driven manually or electrically or in other manners, and the driving member 53 drives the connecting plate 51 to move to adjust the pressing portion 52, which is more labor-saving than directly drawing the connecting plate 51 on the premise of reasonably arranging the driving member 53.

In addition, if the connection plate 51 is manually extended and contracted only from below the floor 200, a worker at a lower floor may touch the connection plate 51 only by stepping on the traveling ladder, in which case it is difficult to press the pressing portion 52 against the floor 200. And adopt driving piece 53 to drive connecting plate 51 and remove, the position of driving piece 53 is more nimble, can set up driving piece 53 in the position of convenient operation.

It is mentioned above that the driving member 53 may be driven manually, electrically or otherwise, for example, the driving member 53 may be a cylinder, and for example, the driving member 53 may be a linear motor.

Specifically, as shown in fig. 4, a threaded hole (not shown) is formed in the connecting plate 51, a threaded rod 532 engaged with the threaded hole is formed in the driving member 53, and the driving member 53 drives the connecting plate 51 to move up and down when rotating. Thus, the driving member 53 can be connected to the connecting plate 51 by the engagement of the threaded rod 532 of the driving member 53 and the threaded hole of the connecting plate 51, so that the driving member 53 can move the connecting plate 51 up and down when rotating.

The threaded hole and the screw rod 532 are matched to be equivalent to a screw rod structure, the connecting plate 51 is driven to move in this way, the rotating motion form is converted into the moving motion form, the structural volume of the driving piece 53 can be very small, and small rotating force can be converted into large pressing force, so that the pressing part 52 can be favorably pressed on the floor slab 200.

The driving member 53 can be a manual driving member 53, and the manual driving member 53 can rotate the screw 532. The driving member 53 may be an electric driving member 53, and the driving member 53 may be a rotating motor.

Further, as shown in fig. 4, the top of the driving member 53 extends from above the body 1, and the top of the driving member 53 is provided with a hand wheel 531. That is, the hand wheel 531 protrudes from above the body 1, so that the worker can easily rotate the hand wheel 531 to rotate the drive screw 532. When the driving member 53 is a manual driving member 53, the hand wheel 531 is arranged to conveniently rotate the screw 532 to adjust the position of the pressing portion 52.

In some alternative embodiments, as shown in fig. 4, the vertical building material transport device 100 further comprises a stop member 7 attached to the body 1 and cooperating with the connecting plate 51. The stop member 7 can cooperate with the connecting plate 51 to clamp the connecting plate 51, so that the stop member 7 can fix and limit the connecting plate 51, and the connecting plate 51 can be fastened in both vertical and horizontal directions. Specifically, after the connection plate 51 moves up and down to press the pressing portion 52 against the lower surface of the floor 200, the stopper 7 may be fitted on the connection plate 51, so that the connection plate 51 may be smoothly fixed to the body 1, so that the pressing portion 52 firmly presses the lower surface of the floor 200.

Specifically, the stopper 7 may be a stopper bolt.

Thus, when the connecting plate 51 needs to be fixed, the stop bolt can be conveniently screwed into the connecting plate 51. When the connecting plate 51 needs to be moved up and down to adjust the position of the pressing portion 52, the stopper bolt can be easily unscrewed from the connecting plate 51. The stop bolt is convenient to disassemble and assemble and can be repeatedly used.
