Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an access platform for a construction site elevator. Background Art

[0002] The Chinese utility model patent with patent number CN217920973U discloses a construction elevator flap device and a construction elevator, wherein the construction elevator flap device includes a flap assembly and a drive assembly. The flap assembly is connected to the bottom plate of the elevator car of the construction elevator; the fixed end of the drive assembly is connected to the elevator car, and the output end of the drive assembly is connected to the flap assembly, and the output end of the drive assembly can drive the flap assembly to flip relative to the bottom plate of the elevator car to overlap between the bottom plate of the elevator car and the floor slab of the floor building, thereby covering the gap to prevent the falling of fragmented materials and ensure the personal safety of construction workers. The construction elevator flap device has a simple structure and is easy to use, which reduces the workload of construction workers and is safe to use.

[0003] However, the utility model still has the following defects:

[0004] From its attachment Figure 1 It can be clearly seen that the flap is hingedly connected to the elevator through a connecting rod and a driving assembly, wherein the driving assembly is an electric push rod; that is, when someone steps on the flap, or pushes construction equipment out of the elevator or into the elevator, even if the flap is also overlapped on the building floor, the gravity borne by the flap will actually be concentrated on the driving assembly and the connecting rod in the form of bending moment, causing the driving assembly and the connecting rod to bend easily, thus affecting the normal use of the flap device. In other words, the load-bearing performance of the flap device of the utility model is extremely poor.

[0005] In addition, the drive components are relatively sophisticated devices such as electric cylinders, pneumatic cylinders, hydraulic cylinders, electric push rods, etc. Once a failure occurs, the maintenance and procurement costs are relatively high. Utility Model Content

[0006] The utility model provides a construction site elevator access platform, which solves the above-mentioned technical problems by arranging a supporting structure rod obliquely connected to the mounting bracket under the supporting bracket so that the supporting structure rod cooperates with the supporting bracket and the mounting bracket to form a triangular supporting structure with better supporting performance, so as to effectively improve the load-bearing performance of the access platform.

[0007] The technical solution of the present utility model to solve the above problems is: to provide a construction elevator access platform, which includes an installation bracket, a support bracket, and a support plate body. The installation bracket is fixedly installed at the entrance and exit of the elevator. The support bracket is located outside the entrance and exit of the elevator and is fixedly connected to the installation bracket. The support plate body is horizontally paved on the support bracket; it also includes a support structure rod with one end connected to the installation bracket and the other end connected to the support bracket. The support structure rod, the installation bracket, and the support bracket cooperate to form a support structure for carrying the support plate body and heavy objects.

[0008] Further, at least one installation through hole is provided on the installation bracket, and at least one first bolt and at least one first nut are also provided at at least one installation through hole. The installation bracket is detachably and fixedly installed on the outside of the elevator through at least one first bolt, at least one first nut, and at least one installation through hole.

[0009] Further, the installation bracket includes a horizontal part and a vertical part, which are integrally connected. The installation through hole is provided on the horizontal part. The horizontal part is used for fixedly installing to the entrance and exit of the elevator, and the vertical part extends downward and is for the support structure rod to be rotatably connected.

[0010] Further, the support bracket includes a bracket sleeve and a bracket body. The bracket body is movably inserted into the bracket sleeve; the bracket body horizontally moves relative to the bracket sleeve to change the overall horizontal length of the support bracket.

[0011] Further, a horizontally extending strip-shaped through hole is also provided on the support bracket. One end of the support structure rod is rotatably connected to the installation bracket, and the other end is provided with a second bolt and a second nut. The second bolt is inserted into the strip-shaped through hole and cooperates with the second nut to clamp and fixedly connect the support structure rod and the support bracket, so that the support structure rod, the installation bracket, and the support bracket are combined to form a triangular support structure.

[0012] Further, the diameter of the second bolt is smaller than the width of the strip-shaped through hole. The second bolt is inserted into different positions of the strip-shaped through hole to cooperate with the second nut to fixedly connect support structure rods of different lengths and the support bracket.

[0013] Further, there is at least one support structure rod.

[0014] Further, the support plate body includes a plurality of plate body units, and the plurality of plate body units are spliced with each other to form the support plate body.

[0015] Further, at least one permanent magnet is fixedly provided on the lower surface of the plate body unit located at the edge of the support plate body. The plate body unit is adsorbed and closely attached to the support bracket through at least one permanent magnet.

[0016] Furthermore, at least one receiving groove for accommodating a permanent magnet is further provided on the support bracket, and the permanent magnet and the receiving groove are mutually blocked and limited in the horizontal direction to limit the horizontal movement of the plate unit located at the edge of the support plate body on the support bracket, thereby restricting the horizontal movement of the entire support plate body.

[0017] Advantages of the utility model:

[0018] For a construction site elevator access platform of the utility model, by obliquely arranging a support structure rod connected to both the installation bracket and the support bracket below the support bracket, the support bracket, the installation bracket, and the support structure rod cooperate with each other to form a triangular support structure with better support performance, so as to effectively protect the support bracket and improve the load-bearing performance of the platform.

[0019] In addition, bolt and nut connection structures are adopted between the installation bracket and the elevator, and between the support bracket and the support structure. The installation and disassembly are convenient, and it can be reused multiple times without being discarded after the building is completed, effectively reducing the manufacturing, installation, and use costs of the platform.

[0020] Moreover, the support bracket is telescopic, and the support plate body is also composed of a plurality of plate units spliced together. Correspondingly, when facing the gap sizes between elevators and buildings of different sizes, construction workers can control the support bracket to extend to just equal the length of the gap, and splice the support plate body into an area that can just cover the gap between the elevator and the building, so as to meet the safe use requirements in different situations, with extremely high flexibility.

The terms "inside" and "outside" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0027] Please refer to Figures 1 to 3 , a construction elevator access platform in a specific embodiment of the present utility model includes two mounting brackets 1, two support brackets 2, and one support plate body 3. The two mounting brackets 1 are respectively fixedly installed on both sides of the elevator entrance and exit. The two support brackets 2 are respectively fixedly connected to one mounting bracket 1, and both support brackets 2 extend horizontally outward from the elevator. Moreover, the heights of the two support brackets 2 are flush. One support plate body 3 is laid and installed on the two support brackets 2 and is simultaneously supported by the two support brackets 2 to carry people or goods.

[0028] Since the installation methods of the mounting brackets 1 and support brackets 2 on both sides of the elevator are exactly the same, only the specific structures and installation methods of the mounting bracket 1 and support bracket 2 on one side will be specifically described in this embodiment. Specifically, the mounting bracket 1 is an L-shaped plate body. The mounting bracket 1 includes a horizontal part 11 and a vertical part 12. The horizontal part 11 and the mounting part are coplanar. The horizontal part 11 is a horizontal plate that is horizontally fixedly attached to the side of the elevator. And when the horizontal part 11 is horizontally fixedly installed at the lower edge of the side of the elevator, the vertical part 12 can vertically extend downward a certain distance below the elevator. At this time, the technician then hingedly installs the lower end of a support structure rod 4 at the lower end of the vertical part 12, and then fixedly connects the other end of the support structure rod 4 to the support bracket 2 in a horizontal position, so that the support structure rod 4, the vertical part 12, and the support bracket 2 cooperate with each other to form a triangular support structure, so that the support bracket 2 can stably support the support plate body 3 and enable the support plate body 3 to have a certain load-bearing performance, improving the use safety of the device of the present utility model.

[0029] In other embodiments, only one mounting bracket 1 may be provided; when there is only one mounting bracket 1, the mounting bracket 1 is a flat plate body, and the mounting bracket 1 is correspondingly fixedly installed at the lower edge of the elevator entrance through the cooperation of a plurality of first bolts 13 and a plurality of first nuts 14. Both support brackets 2 are fixedly connected to the upper edge of the mounting bracket 1 and are flush with the elevator exit floor. Both support brackets 2 also jointly bear the support plate body 3, as well as people and goods passing through the support plate body 3.

[0030] In addition, when there is only one mounting bracket 1, the mounting bracket 1 can also be a special-shaped plate. The horizontal portion 11 is a plate body parallel to the horizontal plane, and the vertical portion 12 is a plate body arranged vertically. The horizontal portion 11 can be detachably fixedly installed on one side of the elevator bottom near the elevator entrance through a plurality of first bolts 13 and a plurality of first nuts 14. At this time, the vertical portion 12 can extend vertically downward from the lower edge position of the elevator exit. Both support brackets 2 are fixedly connected to the upper edge of the vertical portion 12 or the edge of the horizontal portion 11 to be flush with the elevator floor. Both support brackets 2 also jointly bear the support plate body 3. Of course, three or more mounting brackets 1 can also be provided, and each mounting bracket 1 is correspondingly fixedly installed at the lower edge or both sides of the elevator entrance through the first bolts 13, first nuts 14, and mounting through holes 5.

[0031] Moreover, only one support bracket 2 may be provided. When there is only one support bracket 2, the support bracket 2 is a flat grid bracket. The support bracket 2 can be fixedly connected to one or more mounting brackets 1 at the same time to horizontally support between the elevator and the building and for laying the support plate body 3.

[0032] Furthermore, in this embodiment, a mounting through hole 5 is horizontally opened on the horizontal portion 11. The mounting through hole 5 is in a long strip shape, and two first bolts 13 and two first nuts 14 are arranged in one mounting through hole 5 at the same time. One first bolt 13 and one first nut 14 are a set, and both sets of bolt and nut structures are fixedly connected to the elevator by threads to stably fixedly install the mounting bracket 1 on one side of the elevator in a two-point fixing manner. Moreover, when specifically installing and fixing the mounting bracket 1 to one side of the elevator, the construction personnel can first find the existing holes on the side of the elevator and move the first bolts 13 in the mounting through hole 5 to correspond to the existing holes on the side of the elevator, so as to fixedly install the mounting bracket 1 to the side of the elevator without additional drilling; of course, if it is really impossible to find a hole that can be adapted to the first bolts 13 in the mounting through hole 5 at the same time, the construction personnel can also directly drill holes on the side of the elevator to fixedly install the mounting bracket 1. In addition, after the building is completed, the construction personnel can also remove the two sets of bolt and nut structures to remove the device of the present invention for the next use.

[0033] However, in other embodiments, two or more circular mounting through-holes 5 may also be formed in the horizontal portion 11. Only one first bolt 13 is provided in each mounting through-hole 5, and the first bolts 13 in two or more mounting through-holes 5 are correspondingly engaged with a plurality of first nuts 14 to fix the mounting bracket 1 to the side of the elevator.

[0034] Further, in this embodiment, only one support structure rod 4 is provided; while in other embodiments, if it is necessary to further improve the load-bearing performance of the entire access platform, two or more support structure rods 4 may be provided in the above manner.

[0035] Further, in order to enable the access platform of this embodiment to block gaps of different sizes, the support bracket 2 includes a bracket sleeve 21 and a bracket body 22. In this embodiment, the bracket sleeve 21 is a U-shaped sleeve, and the cross-section of the tube body is square. The bracket body 22 correspondingly is a U-shaped solid tube with both ends movably inserted into the bracket sleeve 21, and the cross-section of the tube body is also square. In this embodiment, the construction personnel can control the bracket body 22 to move translationally relative to the bracket sleeve 21, so that the horizontal length of the entire support bracket 2 correspondingly becomes larger or smaller until it is equal to or slightly smaller than the gap size between the target elevator and the target construction building.

[0036] In addition, the two middle void areas of the bracket sleeve 21 and the bracket body 22 correspondingly combine with each other to form a complete strip-shaped through-hole 23. The length of the strip-shaped through-hole 23 changes with the change of the length of the support bracket 2; a second bolt 41 is horizontally rotatably inserted and arranged at the upper right end of the support structure rod 4. The second bolt 41 passes through the strip-shaped through-hole 23 and is threadedly connected with a second nut 42 on the other side of the support bracket 2 to clamp and fix the upper right end of the support structure rod 4 and the support bracket 2 at the same time, thereby fixedly connecting the support structure rod 4 and the support bracket 2, so that the support bracket 2, the mounting bracket 1, and the support structure rod 4 are fixedly connected end to end in sequence to form a stable triangular support structure, thereby effectively bearing the support plate body 3 and the heavy objects on the support plate body 3.

[0037] Moreover, the diameter of the second bolt 41 is also smaller than the width of the strip-shaped through-hole 23; in this regard, the upper right ends of support structure rods 4 of different lengths can all find fixed positions at the strip-shaped through-hole 23 to be fixedly connected with the support bracket 2, so as to further improve the use flexibility of the access platform of this embodiment.

[0038] In addition, the support plate body 3 also includes a plurality of plate units 31, and the plurality of plate units 31 are spliced with each other to form the support plate body 3; correspondingly, the construction personnel can also increase or decrease the number of plate units 31 so that the support plate body 3 correspondingly just covers or is slightly smaller than the gap between the elevator and the construction building.

[0039] Furthermore, in this embodiment, the plate unit 31 is a rectangular plate, and each plate unit 31 is simultaneously lapped on two support brackets 2 along the length direction. A plurality of plate units 31 are spliced end to end along their width direction to form a complete support plate 3.

[0040] It should be noted that: in this embodiment, along the width direction of the plate unit 31, a permanent magnet 32 is fixedly arranged on the lower surfaces of the plate units 31 at the head and tail ends of the support plate 3. The support brackets 2 are correspondingly made of magnetically attractable metal, and accommodation grooves 24 for accommodating and restricting the permanent magnet 32 from moving in the four directions of front, back, left, and right in the horizontal plane are opened at both ends of the support brackets 2; at the same time, among any two adjacent plate units 31, a splicing groove is opened on the adjacent side surface of one plate unit 31, and a splicing protrusion is opened on the adjacent side surface of the other plate unit 31. The splicing protrusion and the splicing groove are mutually adapted. In this regard, the construction workers can first install the plate units 31 at the head and tail ends, then lay the corresponding number of plate units 31 between the two plate units 31, and splice these plate units 31 in sequence; at this time, the plate units 31 at both ends can be tightly attached to the support brackets 2 under the magnetic attraction and the limiting action of the accommodation grooves 24, and the plurality of plate units 31 between the plate units 31 at both ends can also be stably laid on the support brackets 2 under the mutual limiting action of the splicing grooves and the splicing protrusions and the limiting action of the plate units 31 at both ends, and will not move easily, so as to ensure the safety when stepping on the support plate 3 or carrying goods in and out of the elevator.

[0041] Moreover, after the construction of the building is completed, the construction workers can also quickly disassemble the support plate 3 for the next use.

[0042] For the parts not mentioned above, the prior art is applicable.

[0043] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
