Description

Technical Field

[0001] This application relates to the technical field of unloading platforms, and in particular to a self-climbing unloading platform. Background Technology

[0002] Self-climbing unloading platforms are used in high-rise buildings for material handling. They typically employ a pre-embedded structure reliably connected to the main structure, and are lifted to the designated position via an electric hoist along guide rails. Due to their advantages of simple and quick operation and cyclical use after a single installation, they are increasingly widely used in the construction of high-rise buildings.

[0003] In practice, hoisting equipment is typically used to lift materials onto an unloading platform, from which workers on the corresponding floor then move the materials. However, workers need to enter the unloading platform to move materials, and the platform is usually not very large, which can limit the convenience and efficiency of workers moving goods on it. Summary of the Invention

[0004] To facilitate the transport of goods from the platform to the floors, this application provides a self-climbing unloading platform.

[0005] The technical solution adopted in this application is as follows:

[0006] A self-climbing unloading platform includes a platform body with a receiving cavity, a sliding plate sliding in the platform body, and a driving assembly for driving the sliding plate to slide. The bottom surface of the sliding plate is provided with pulleys. The driving assembly can drive the sliding plate to slide into the receiving cavity of the platform body or slide out from one end of the platform body. The driving assembly is provided with a locking member, which can be used to position the sliding plate when it is in the receiving cavity or when it slides out from the platform body.

[0007] By adopting the above technical solution, the sliding plate is installed in the platform body via pulleys and can be positioned by locking components. After the material is hoisted onto the sliding plate, the sliding plate is driven out by the drive assembly, allowing workers to unload materials from within the floor. The locking components also position the sliding plate during unloading, preventing it from sliding arbitrarily.

[0008] Optionally, the drive assembly includes a drive rod rotatably connected to the platform body and a power source for driving the drive rod to rotate; a rack is provided at the bottom of the sliding plate, the length direction of the rack is parallel to the sliding direction of the sliding plate, and a gear is coaxially provided on the outer wall of the drive rod, the gear being able to mesh with the rack.

[0009] By adopting the above technical solution, the gear and rack can mesh, and when the power source drives the drive rod to rotate, it can drive the sliding plate to slide.

[0010] Optionally, the sliding plate has a first plate and a second plate on the side near the drive rod. There are two of each type of plate. The two first plates are symmetrically arranged on both sides of the rack, and the two second plates are symmetrically arranged on both sides of the rack, with the two first plates located between the two second plates. The outer wall of the drive rod has symmetrically arranged threaded portions with opposite threads. The locking member includes two symmetrically threaded locking blocks connected to the outer wall of the drive rod. A guide structure is provided between the locking blocks and the platform body, so that when the drive rod rotates, the two locking blocks can move closer to each other to abut against the opposite side of the two first plates, or move away from each other to abut against the opposite side of the two second plates.

[0011] By adopting the above technical solution, when the sliding plate is in the platform body, the two locking blocks approach each other and press against the first plate, thereby positioning the sliding plate; during unloading, the sliding plate slides out of the platform body, and the locking blocks move away from each other and press against the second plate, thereby positioning the sliding plate.

[0012] Optionally, one end of the rack away from the platform body outlet is hinged to the sliding plate, and the other end of the rack is provided with a clearance groove. A limiting rod extending into the clearance groove is installed on the sliding plate. A positioning member for positioning the rack is provided on the first plate. An extension portion that slides through the first plate is installed on the positioning member, and an abutment member is provided at the end of the positioning member away from the extension portion. When the locking blocks approach each other and abut against the extension portion, the positioning effect of the positioning member on the rack can be released, and the abutment member can drive the rack to rotate upward so that the rack and the gear disengage from contact.

[0013] By adopting the above technical solution, when the sliding plate is driven to slide, the positioning component can position the rack, so that the gear and rack can mesh well. When the locking block abuts against the extension, the positioning block begins to release the positioning effect on the rack. Under the action of the abutting component, the rack rotates upward, and the gear and rack mesh. At this time, the drive rod continues to rotate, and the locking blocks move closer to each other and abut against the first plate. This makes the positioning effect of the locking block on the first plate good and prevents wear on the side of the first plate that contacts the locking block.

[0014] Optionally, the positioning element includes a positioning plate hinged to the first plate, and a positioning block is provided at one end of the positioning plate. The side wall of the rack is provided with a slot. An elastic element is installed between the positioning plate and the first plate. Under the action of the elastic element, the positioning block abuts against the slot to restrict the rack from rotating. The extension is located at the end of the positioning plate away from the positioning block.

[0015] By adopting the above technical solution, when the positioning block is engaged in the slot, the rack is not easy to rotate under the limiting effect of the positioning block. When the extension is pressed by the locking block and drives the positioning plate to rotate, the positioning block is disengaged from the slot, releasing the positioning effect on the rack, so that the rack can be pressed by the abutment and rotate.

[0016] Optionally, the abutting member includes an abutting block mounted on the positioning plate. The abutting block has an inclined surface on the side near the rack. When the locking block abuts against the extension so that the positioning block disengages from the slot, the inclined surface of the abutting block can abut against the edge of the slot and drive the rack to rotate upward.

[0017] By adopting the above technical solution, the inclined surface of the contact block abuts against the edge of the slot, thereby pushing the rack upward and causing the rack and gear to disengage.

[0018] Optionally, the guide structure includes a guide groove disposed within the platform body, and the lower end of the locking block extends into the guide groove.

[0019] By adopting the above technical solution, the locking block slides more stably under the guidance of the guide groove.

[0020] Optionally, symmetrical limiting grooves are provided on the inner wall of the platform body, and the side of the sliding plate can be inserted into the limiting grooves.

[0021] By adopting the above technical solution, the stability of the sliding plate is improved, and the sliding plate is less likely to deviate when sliding.

[0022] In summary, this application includes at least one of the following beneficial effects:

[0023] 1. A sliding plate is installed on the unloading platform. Materials can be placed on the sliding plate and then the sliding plate can be slid out, so that materials can be unloaded on the floor.

[0024] 2. The sliding plate can be positioned by the cooperation of the locking block, the first plate and the second plate, thereby improving the stability of the sliding plate during loading or unloading. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses a self-climbing unloading platform. (Refer to...) Figure 1 The self-climbing unloading platform includes a platform body 1, which has a receiving cavity. The platform body 1 is installed by guide rails vertically mounted on the floor and moves up and down by means of an electric hoist or similar means. The installation and use of the platform body 1 are existing technologies and are not the focus of this application, so they will not be described in detail here.

[0033] Reference Figure 2 A sliding plate 2 is horizontally slidably installed in the platform body 1. Rollers 4 are installed at the four corners of the lower surface of the sliding plate 2, allowing it to slide within the platform body 1. The end of the platform body 1 closest to the floor is the unloading outlet. During installation, the inner bottom surface of the receiving cavity of the platform body 1 is flush with the floor floor. Materials are typically hoisted into the platform body 1 using hoisting equipment, and then the sliding plate 2 slides out of the platform body 1 and onto the floor, allowing workers to unload the goods from there.

[0034] Reference Figure 2 and Figure 3To facilitate the sliding of the sliding plate 2, a drive assembly 3 is installed on the platform body 1 to drive the sliding plate 2 into or out of the platform body 1. The drive assembly 3 includes a drive rod 31 rotatably mounted on the platform body 1 and a power source 32 for driving the drive rod 31 to rotate. The power source 32 is a motor. The drive rod 31 rotates on the platform body 1 via bearings or other means. The drive rod 31 is horizontally positioned and located on the platform body 1 near the discharge opening. A gear 33 is coaxially fixed on the outer wall of the drive rod 31. A rack 34 is installed on the lower surface of the sliding plate 2. The length direction of the rack 34 is parallel to the sliding direction of the sliding plate 2, and the gear 33 can mesh with the rack 34. When the drive rod 31 rotates, it can drive the sliding plate 2 to slide. When the sliding plate 2 slides out of the platform body 1, most of the sliding plate 2 slides out of the platform body 1, thus facilitating unloading.

[0035] Furthermore, to reduce slippage of the sliding plate 2 during loading and unloading, a locking element 5 is installed on the drive assembly 3 to position the sliding plate 2. Two first plates 6 and two second plates 7 are mounted on the bottom surface of the sliding plate 2. The two first plates 6 are symmetrically mounted on both sides of the rack 34, and the two second plates 7 are also symmetrically mounted on both sides of the rack 34, with the two first plates 6 positioned between the two second plates 7. The drive rod 31 has symmetrically threaded portions on the outer wall of its portion inside the platform body 1, with the thread directions opposite. The locking element 5 includes locking blocks 51 symmetrically threaded to the threaded portions. The locking blocks 51 are also symmetrically located on both sides of the rack 34, and a guide structure exists between the locking blocks 51 and the platform body 1. When the drive rod 31 rotates, the two locking blocks 51 can move closer or further apart. When the sliding plate 2 slides into the platform body 1, the locking blocks 51 move closer together and press against the first plates 6, thereby positioning the sliding plate 2. When the sliding plate 2 slides out of the platform body 1, the locking blocks 51 move away from each other and press against the second plate 7, thereby positioning the sliding plate 2.

[0036] In a further embodiment, the guide structure includes a guide groove 9 disposed on the surface of the platform body 1, and the lower end of the locking block 51 extends into the guide groove 9. Under the limiting action of the guide groove 9, the rotation of the locking block 51 can be restricted, so that when the drive rod 31 rotates, it can drive the locking block 51 to slide.

[0037] Reference Figure 3 and Figure 4In a further embodiment, the end of the rack 34 furthest from the outlet of the platform body 1 is hinged to the bottom surface of the sliding plate 2. The end of the rack 34 can be hinged to the sliding plate 2 in the form of a hinge seat, so that the rack 34 can rotate around the hinge point as the center point. A relief groove 10 is provided on the end face of the rack 34 furthest from the hinge point. A limiting rod 11 is fixed on the sliding plate 2. The limiting rod 11 has an L-shaped structure, and the end of the limiting rod 11 extends into the relief groove 10. The relief groove 10 is larger than the size of the limiting rod 11. When the limiting rod 11 abuts against the upper inner wall of the relief groove 10, the rack 34 is in a horizontal state.

[0038] A positioning element 12 for positioning the rack 34 is installed on the first plate 6. The positioning element 12 is located on the side of the first plate 6 facing the rack 34. Under the action of the positioning element 12, the rack 34 is less likely to rotate when the gear 33 and the rack 34 are engaged. An extension 13 and an abutment 14 are installed on the positioning element 12. The extension 13 slides through the first plate 6 and has a portion that extends beyond the surface of the first plate 6. The abutment 14 is located on the side of the positioning element 12 closer to the rack 34. When the sliding plate 2 slides into the platform body 1, the locking blocks 51 approach each other and first abut against the extension 13, thereby driving the positioning element 12 to move, so that the positioning element 12 releases its positioning effect on the rack 34. Then the abutment 14 abuts against the rack 34 and drives the rack 34 to rotate upward, thereby causing the gear 33 and the rack 34 to disengage. The locking blocks 51 continue to approach each other and can then abut against the first plate 6.

[0039] Reference Figure 4 and Figure 5 The positioning component 12 includes a positioning plate 121 hinged to the first plate 6. The positioning plate 121 is hinged to the first plate 6 via a hinge seat, and the hinge point of the positioning plate 121 is located in the middle of the positioning plate 121. A positioning block 122 is fixed to one end of the positioning plate 121. A slot 15 is formed on the side wall of the rack 34, extending horizontally. An elastic element 16, which is a spring, is installed on the side of the positioning plate 121 opposite to the positioning block 122. One end of the spring is connected to the first plate 6, and the other end is connected to the positioning plate 121. Under the elastic force of the spring, the positioning block 122 can abut against the slot 15, and when the sliding plate 2 slides, the positioning block 122 can slide relative to the slot 15. Under the limiting action of the positioning block 122 and the slot 15, the rack 34 cannot rotate.

[0040] The extension 13 has a block-like structure and is fixed to the positioning plate 121 on the side opposite to the rack 34. The extension 13 slides through the first plate 6. The first plate 6 has an opening larger than the extension 13. Under the action of the elastic member 16, the positioning block 122 abuts against the slot 15. One end of the extension 13 passes through the first plate 6 and has a portion extending beyond the surface of the first plate 6. The abutting member 14 includes an abutting block 141 mounted on the positioning plate 121. The abutting block 141 is located at the end away from the positioning block 122, and the height of the abutting block 141 is higher than the height of the positioning block 122. The end of the abutment block 141 near the rack 34 has an inclined surface 142. When the locking blocks 51 approach each other and abut against the extension 13, the positioning plate 121 begins to rotate, causing the positioning block 122 to gradually disengage from the slot 15. The abutment block 141 then gradually moves towards the rack 34, and the edge of the slot 15 abuts against the inclined surface 142 of the abutment block 141, thereby gradually driving the rack 34 to rotate upward, causing the gear 33 and the rack 34 to disengage. Then, the locking block 51 abuts against the first plate 6. When the locking blocks 51 move away from each other, the abutment block 141 disengages from the slot 15, and the rack 34 can reset. To improve the reset effect of the rack 34, a spring is also installed between the upper surface of the rack 34 and the sliding plate 2. When the rack 34 moves upward, the spring is compressed, thus providing the reset force for the rack 34.

[0041] Referring to the figure, friction pads 18 are provided on the opposite sides of the second plate 7 and the locking block 51. When the sliding plate 2 slides out of the platform body 1, the friction pads 18 can abut against each other, thereby improving the positioning effect of the sliding plate 2. Furthermore, in order to improve the sliding stability of the sliding plate 2, a limiting groove 17 is installed on the inner wall of the platform body 1. The edge of the sliding plate 2 abuts against the limiting groove 17, making the sliding plate 2 more stable when sliding.

[0042] The implementation principle of a self-climbing unloading platform according to an embodiment of this application is as follows: when the sliding plate 2 is in the platform body 1, the locking block 51 abuts against the first plate 6 to position the sliding plate 2. When the material is placed on the sliding plate 2, the sliding plate 2 is driven to slide out by the driving component 3. Then the locking block 51 abuts against the second plate 7 to position the sliding plate 2, and then personnel can unload the material.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
