Description

Technical Field

[0001] The present invention relates to the technical field of construction transportation equipment, and particularly relates to a vertical transportation device for on-site construction. Background Art

[0002] Vertical transportation at indoor material transfer ports is a technology that realizes cross-floor material transportation by setting up a dedicated vertical channel (material transfer port) in a building or production environment and combining mechanical or automated systems. Its core goal is to efficiently and safely complete the transfer of building materials between different structural layers during construction, especially in scenarios such as high-rise buildings and decoration projects (such as EPS lines and dry-hanging stones).

[0003] In narrow indoor construction sites, due to limited space and decentralized transportation requirements, a simple vertical transportation solution of hanging a 3T-class chain electric hoist on a portal frame is generally adopted at present. Its basic process is as follows: 1. Hang the electric hoist outside the scaffold and lift the materials to the scaffold platform through a steel wire rope; 2. Manually transfer the materials to the working surface through a gangplank. However, this transportation method has the following safety hazards and technical defects:

[0004] 1. Insufficient structural safety: Eccentric loads cause the instability of the frame. The single-point suspension operation of the electric hoist generates a lateral eccentric load, resulting in the horizontal displacement of the scaffold exceeding the design requirements and significantly reducing the overall stability of the frame. There is a risk of node loosening. When transporting heavy materials (such as stones and metal components), the dynamic load impact during the start and stop stages of the electric hoist is likely to cause the loosening of the fastener connection nodes, forming an overturning hazard.

[0005] 2. Low construction efficiency: Secondary handling is time-consuming and laborious. After the materials are lifted to the scaffold platform, they need to be manually transferred to the working surface through a gangplank, which additionally increases the working hours, and the passage of the gangplank is likely to cause the risk of personnel falling.

[0006] 3. Conflict in space occupation: When setting up the scaffold, a working surface needs to be reserved, further compressing the available space in the narrow site and conflicting with the moving lines of construction machinery and personnel.

[0007] Based on this, the present invention proposes a vertical transportation device for indoor transfer construction to solve the problems existing in the above-mentioned prior art. Summary of the Invention

[0022] Compared with the prior art, the present invention provides a vertical transportation device for on-site construction, which has the following

[0023] Advantages:

[0024] 1. Through the arrangement of the transportation mechanism, the vertical operation of materials at the indoor material transfer port can be realized, and the overall transportation process is inside the construction frame, which will not affect the stability of the construction frame. During transportation, the center of gravity is stable, ensuring that the materials are inside the storage rack and will not shake. The cooperation between the telescopic plate and the positioning plate can limit the materials in the storage rack and position them during the vertical transportation of the materials, so that the materials will not tilt or shake, improving the stability of the vertical operation of the materials;

[0025] 2. Through the cooperation between the clamping block and the clamping plate, the storage rack can be locked when the storage rack stops, ensuring the stability of the operation of the transportation mechanism. Moreover, locking is carried out on both sides simultaneously, with better stability and more convenience for taking materials. When the electric drive wheel is running, the corresponding scraper will scrape the surface of the slide rail to avoid the slide rail being affected by on-site impurities and ensure the stable operation of the electric drive wheel;

[0026] 3. By setting up the transfer and moving mechanism, two support frames are used to increase the overall force points of the device, thereby increasing the overall stability of the device, and the hydraulic cylinder can adjust the height of the universal wheel. When the device needs to move, the universal wheel can be used to contact the ground, and the bottom end of the transport mechanism and the support frame can be lifted off the ground, which can assist the device in transporting and improve the applicability of the device. At the same time, when the transport mechanism is in use, the transfer and moving mechanism can be used to complete the short-distance transport of materials. This solves the problems of insufficient structural safety, low construction efficiency and space occupancy contradictions in traditional indoor vertical transportation systems.

[0041] The following further elaborates in detail on the structure and process of the vertical transportation device for on-site construction in combination with the accompanying drawings and embodiments of the present invention.

[0042] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will elaborate on the present invention in detail with reference to the accompanying drawings and embodiments.

[0046] The following combines the description of the Figures 1 - 11 vertical transportation device for on-site construction of the present invention with the attached drawings of the specification.

[0047] Embodiment 1:

[0048] Embodiment 1 of the present invention - Figure 10 provides a vertical transportation device for on-site construction, which is used for the vertical transportation of materials at the material transfer opening 11 of the indoor floor slab 1, and includes a transportation mechanism 2 and a transfer and moving mechanism 3, where:

[0049] When in use, the transportation mechanism 2 is installed between the lower floor slab 1 and the upper floor slab 1, and the lower end of the transportation mechanism 2 is connected to the lower floor slab 1, and the upper end penetrates through the material transfer opening 11 of the upper floor slab 1 and is connected to the floor slab 1 where the material transfer opening 11 is located. The transportation mechanism 2 includes a slide rail 21 and a storage rack 4; the slide rail 21 is installed between the lower floor slab 1 and the upper floor slab 1, and the lower end of the slide rail 21 is connected to the lower floor slab 1, and the upper end penetrates through the material transfer opening 11 of the upper floor slab 1 and is connected to the floor slab 1 where the material transfer opening 11 is located; the storage rack 4 is movably installed on the slide rail 21, and two mounting frames 5 are fixedly connected to one side of the storage rack 4 close to the slide rail 21, and electric drive wheels 51 are provided at both ends of the mounting frame 5, and the electric drive wheels 51 are meshed with the slide rail 21, and limiting components are provided on both sides of the storage rack 4 to limit the materials;

[0050] When transferring, the transfer and moving mechanism 3 is detachably installed at the lower end of the slide rail 21, which serves to facilitate the movement of the transportation mechanism 2; when the slide rail 21 is in use, the transfer and moving mechanism 3 is used for the short-distance transportation of materials, facilitating workers to place the materials on the storage rack 4.

[0051] In the above description, the transportation mechanism 2 can be assembled between the lower floor slab 1 and the upper floor slab 1 of the corresponding layer according to the on-site construction requirements. During use, according to the construction requirements, multiple transportation mechanisms 2 can be assembled between the floor structures of different floors of the building body to complete the multi-level transportation of indoor construction of the building structure. During use, after moving the transportation mechanism 2 to the corresponding position, workers transfer the materials from the ground to the storage rack 4 and control the action of the electric drive wheel 51. Under the driving action of the electric drive wheel 51, the storage rack 4 is driven to move along the length direction of the slide rail 21 to perform the vertical transportation of the materials at the construction site. The materials at the construction site include construction equipment, cement, and some decoration materials, etc.

[0052] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the overall shape of the slide rail 21 is L-shaped, and a buffer pad 211 is provided at the bent part at the lower end of the slide rail 21. The buffer pad 211 is a rubber material component, which is used to buffer and shock-absorb when the storage rack 4 contacts the buffer pad 211 to protect the storage rack 4.

[0053] Specifically, as Figure 1 and Figure 2 shown, the storage rack 4 is a drawer-like structure, and the axis of the storage rack 4 is parallel to the axis of the slide rail 21. A restraint plate 48 is rotatably provided on the front side of the storage rack 4, and a plurality of round holes are provided on the storage rack 4 and the restraint plate 48. The round holes can automatically discharge the material residues and reduce the weight of the storage rack 4 and the restraint plate 48, thereby avoiding the residue of impurities in the storage rack 4 and reducing the influence of the external environment on the storage rack 4. When it is parallel to the slide rail 21, the transportation stability is better.

[0054] Specifically, as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a limiting plate 49 is fixedly connected to the inner side of the bottom of the storage rack 4, and the cross-section of the limiting plate 49 is a right triangle. The limiting plate 49 can limit the bottom end of the materials in the storage rack 4 to improve the stability of the materials in the storage rack 4.

[0055] Specifically, as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the restraint plate 48 is rotatably installed at the front opening of the storage rack 4 through a hinge plate, and a buckle structure is provided at the free end of the rotation of the restraint plate 48 to be clamped with the storage rack 4 to realize the locking of the restraint plate 48 during use and avoid the occurrence of material scattering during the vertical transportation of the materials.

[0056] Specifically, 1. Figure 2 , Figure 3 and Figure 5 As shown, a positioning steel member 22 is detachably installed at the upper end of the slide rail 21. A plurality of positioning holes are provided on the positioning steel member 22 for connecting with the upper floor slab 1 during installation and fixing to complete the fixing and installation of the slide rail 21.

[0057] In a preferred embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the limiting components are symmetrically installed in the chutes on the two side walls of the storage rack 4, and include a telescopic plate 41 and a positioning plate 43. The telescopic plate 41 penetrates through the two side walls of the storage rack 4 and is movably installed in the chutes on the two side walls of the storage rack 4. A first spring 42 is provided at one end of the telescopic plate 41 close to the outer side of the side wall of the storage rack 4, and the other end of the first spring 42 is fixedly connected to the outer side wall of the storage rack 4. It is used to make the two telescopic plates 41 slide left and right along the chute during use through the buffering and resetting effects of the first spring 42 after deformation, so as to clamp the transported materials and buffer the vibration during transportation, and realize the stable transportation of the materials during transportation. The positioning plate 43 is arranged at the other end of the telescopic plate 41 and is located inside the storage rack 4. A second spring 44 is also provided at the connection between the positioning plate 43 and the telescopic plate 41. One end of the second spring 44 is connected to the telescopic plate 41, and the other end is connected to the positioning plate 43. It is used to make the two positioning plates 43 move back and forth inside the storage rack 4 through the buffering and resetting effects of the second spring 44 during use, so as to clamp and position the transported materials with different volumes.

[0058] In the above description, after the strip-shaped material is placed in the storage rack 4, the material will first squeeze the two side positioning plates 43, drive the two telescopic plates 41 to move relatively outward, the first spring 42 will be stretched. After the material fits with the storage rack 4, under the influence of the shape of the positioning plate 43, the positioning plate 43 will move outward, and then drive the second spring 44 to be stretched, automatically fitting the surface of the material. Under the action of the first spring 42 and the second spring 44, the telescopic plate 41 and the positioning plate 43 automatically reset, realizing the locking and positioning of the material and preventing the material from falling during transportation.

[0059] Specifically, as Figure 5 , Figure 6 and Figure 7As shown, at one end of the telescopic plate 41 close to the outer side of the side wall of the storage rack 4, a first guiding column 46 is also provided to cooperate with the first spring 42 to guide the expansion and contraction of the first spring 42; at one end of the telescopic plate 41 close to the outer side of the side wall of the storage rack 4, a handle 45 is also provided. The overall shape of the handle 45 is U-shaped. The U-shaped handle 45 can make the operation of the telescopic plate 41 more convenient, facilitating the taking of materials, and can be reasonably selected according to the on-site construction conditions; on the positioning plate 43, a second guiding column 47 is also provided, and the second guiding column 47 cooperates with the second spring 44 to facilitate guiding the expansion and contraction of the second spring 44 during use.

[0060] Specifically, as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, the cross-section of the positioning plate 43 is trapezoidal, and a plurality of rotating rollers 431 are installed on one surface of the opposite sides of the two positioning plates 43; therefore, when placing materials between the two positioning plates 43, the rotation of the rotating rollers 431 will not affect the vertical movement of the materials between the two positioning plates 43, and the trapezoidal positioning plate 43 also facilitates the taking of materials (it is convenient to press and lock the materials by squeezing the positioning plate 43 forward through the shape during use, and at the same time, the materials can be conveniently removed after being transported in place through the action of the inclined surface).

[0061] In a preferred embodiment, as Figure 3 , Figure 4 and Figure 9 shown, the electric drive wheel 51 is installed on the rear side of the storage rack 4 through the mounting frame 5, behind the slide rail 21. The slide rail 21 is located between the storage rack 4 and the electric drive wheel 51, and a plurality of grooves are formed on the surface of the electric drive wheel 51 and meshed with the rack provided on the rear side of the slide rail 21. The electric drive wheel 51 is also fixedly connected to the drive motor 57 provided outside the mounting frame 5.

[0062] In the above description, by turning on the drive motor 57 to drive the electric drive wheel 51 to rotate, and then driving the mounting frame 5 to move along the length direction of the slide rail 21 through the meshing force between the electric drive wheel 51 and the rack on the rear side of the slide rail 21, so that the storage rack 4 can play the role of material transportation. The slide rail 21 is a common component in the art and will not be elaborated here.

[0063] Specifically, as Figure 7As shown in the figure, scraping plates 56 are fixedly connected to the opposite sides of the two electric drive wheels 51. One end of the scraping plate 56 away from the electric drive wheel 51 is meshed and connected to the slide rail 21. Through the arrangement of the scraping plate 56, when the electric drive wheel 51 runs on the slide rail 21, the scraping plate 56 will move synchronously with it and scrape the impurities on the surface of the slide rail 21, avoiding the influence of on-site impurities on the slide rail 21 and ensuring the stable operation of the electric drive wheel 51.

[0064] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 7 shown, two clamping plates 54 are also fixedly connected to the middle of the side of the storage rack 4 close to the slide rail 21. A plurality of clamping holes 55 are formed in the clamping plates 54. An electric push rod 52 is fixedly connected to the middle of the mounting rack 5, and a clamping block 53 matching the clamping holes 55 is fixedly connected to the telescopic end of the electric push rod 52. When the storage rack 4 needs to stop during transportation, the electric push rod 52 is started to act. The electric push rod 52 will drive the clamping block 53 into the clamping holes 55 to lock the plurality of electric drive wheels 51 on the slide rail 21, thereby locking the storage rack 4. The mutual cooperation of the clamping block 53 and the clamping plate 54 can lock the storage rack 4 when the storage rack 4 stops, determine the stability of the operation of the transportation mechanism 2, and the locking on both sides at the same time has better stability and is also more convenient when taking materials.

[0065] In a preferred embodiment, as Figure 3 , Figure 4 and Figure 11 shown, the transfer moving mechanism 3 is movably installed at the bottom of the slide rail 21, including a bottom frame 31 arranged at the bottom end of the slide rail 21. A support frame 32 is fixedly connected to the bottom end of the bottom frame 31. The support frame 32 is in a structure similar to a "return" shape. And a hydraulic cylinder 33 is also arranged at the bottom end of the bottom frame 31 at the hollow part of the support frame 32. A universal wheel 34 is fixedly connected to the bottom end of the hydraulic cylinder 33.

[0066] In the above description, when the transportation mechanism 2 needs to be transferred, the hydraulic cylinder 33 is started, and the universal wheels 34 will contact the ground. By continuously starting, the bottom ends of multiple construction frames 1 can be separated from the support frame 32, assisting in the transfer of the device. At the same time, through the setting of the transfer and movement mechanism 3, the overall stress points of the device can be increased by using the two support frames 32, enhancing the overall stability of the device. Moreover, the hydraulic cylinder 33 can adjust the height of the universal wheels 34. When the device needs to move, the universal wheels 34 can be used to contact the ground, separating the bottom ends of multiple construction frames 1 from the support frame 32. The height of separation should not be too high, which can assist in the transfer of the device, improving the applicable range of the device. The vertical movement trajectory of the universal wheels 34 is located within the support frame 32, with better stability. And through the setting of the transfer and movement mechanism 3, small-range transfer of materials can also be completed.

[0067] Specifically, as Figure 11 shown, the transfer and movement mechanism 3 further includes a connection block 35 and a fastening bolt 36 fixedly connected to the top end of the chassis 31. The connecting end of the fastening bolt 36 sequentially passes through the connection block 35 and the slide rail 21, and is threadedly connected to both the connection block 35 and the slide rail 21, realizing the detachable connection between the chassis 31 and the slide rail 21. And when the transfer and movement mechanism 3 is not in use, the fastening bolt 36 can be disassembled, and the connection block 35 and the slide rail 21 are separated, enabling the entire transfer and movement mechanism 3 to be detached, improving the applicable range of the device.

[0068] The working principle of the vertical transportation device for on-site construction described in the present invention includes: using the transfer and movement mechanism 3 to move the transportation mechanism 2 to the position of the material transfer opening 11 on the upper floor slab 1 between the lower floor slab 1 and the upper floor slab 1, removing the transfer and movement mechanism 3 (if required, the transfer and movement mechanism 3 can also not be removed), and installing the transportation mechanism 2 between the lower floor slab 1 and the upper floor slab 1, and making the upper end of the slide rail 21 pass through the material transfer opening 11 and fixing the slide rail 21 on the floor slab 1; then placing the material in the storage rack 4, the material will first squeeze the positioning plate 43, driving the two telescopic plates 41 to move relatively outward, the first spring 42 is stretched, after the material fits with the storage rack 4, under the influence of the shape of the positioning plate 43, the positioning plate 43 will move outward, the second spring 44 is stretched, automatically fitting the surface of the material, under the action of the first spring 42 and the second spring 44, the telescopic plate 41 and the positioning plate 43 automatically reset, locking and positioning the material. After the material is placed, the cooperation of the electric drive wheel 51 and the slide rail 21 can be used to realize the vertical movement of the material and transport the material to the upper floor slab 1, completing the transfer of materials from the lower layer to the upper layer during the construction process.

[0069] It should be noted that the construction frame 1, the slide rail 21, the electric drive wheel 51, the electric push rod 52, the hydraulic cylinder 33, the universal wheel 34, etc. in the above description are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the electric drive wheel 51 and the electric push rod 52 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0070] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0071] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
