Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a unloading platform for building construction. Background Art

[0002] With the development of society, high-rise buildings are becoming increasingly important in urban construction, and the scale of high-rise building construction is getting larger and larger. As we all know, during the construction process, the safety enclosure of high-rise buildings is relatively strict. The transfer of materials between floors is generally carried out by vertical transportation vehicles. Unloading platforms are transfer stations that transport materials, equipment and construction tools required by the construction site to the construction floor, or transport garbage and waste generated by construction to the ground. Therefore, unloading platforms have been widely used in high-rise buildings.

[0003] In the prior art, when the unloading platform unloads the material on the unloading plate, the positioning rod is driven out of the fixed groove by the shift rod, and the positioning of the positioning part on the bottom plate is released so that the bottom plate moves toward the inside of the building. When the material on the unloading platform is unloaded and transported to the inside of the floor building, the main body is still implemented by manual unloading.

[0004] Although there are related unloading drive devices in the existing technical patents, the transmission structure and drive structures such as motors and cylinders of this type of drive equipment itself occupy a large amount of load, resulting in a heavy equipment load on the unloading platform, which does not meet actual operational requirements. Summary of the Invention

[0005] The purpose of the present invention is to provide a material unloading platform for building construction to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0008] A load-bearing frame is provided on the platform support, the cargo platform frame is slidably mounted on the load-bearing frame, and a sliding support for connection is provided between the cargo platform frame and the load-bearing frame;

[0009] The rear edge of the cargo platform frame is further provided with an inner support, and the platform support is provided with a lifting member that matches the inner support. After the inner support moves to contact the lifting member, the cargo platform frame tilts with the sliding support as the fulcrum;

[0010] The inner edge of the cargo platform frame is also provided with a pusher, a counterweight that slides as the cargo platform frame tilts, and a transmission assembly connected between the pusher and the counterweight; after the counterweight slides, the pusher is pulled toward the inner edge by the transmission assembly.

[0013] As a further solution of the present invention: the internal support includes a rear base installed on the bottom of the cargo platform frame, a rear bracket arranged on the rear base, and a slope block installed on the rear bracket; the lifting member includes a fixed block arranged on the inner edge of the platform support, and a resistance block installed on the fixed block and connected to the slope block; the contact surface between the slope block and the resistance block is an inclined surface structure.

[0014] As a further solution of the present invention: an electric contact connector is provided between the slope block and the interference block. When the slope block moves to the end point of the contact surface of the interference block, the electric contact connectors of the two coincide with each other, and the electric contact connector is connected to the driving end of the inner drive screw by an electrical signal.

[0015] As a further solution of the present invention: the pushing member includes a pushing claw arranged on the inner edge of the cargo platform frame, a sliding plate installed on the pushing claw, and a connecting block arranged on the sliding plate; the transmission assembly includes a positioning bolt arranged at the center line position inside the cargo platform frame, and transmission connecting rods are arranged on both sides of the positioning bolt, and the rod ends of the transmission connecting rods are respectively connected to the corresponding connecting blocks.

[0016] As a further solution of the present invention: the counterweight includes a median slide bar installed at the midline position of the cargo platform frame, a sliding sleeve mounted on the median slide bar, and a return spring wound around the median slide bar, a counterweight lead block is provided on the sliding sleeve, the other end of the return spring is connected to the sliding sleeve, and the sliding sleeve is connected to the corresponding transmission connecting rod through a linkage connecting rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention is designed to load materials in the inner frame space of the cargo platform frame, and the cargo platform frame is mounted on the load-bearing frame in a sliding manner. When unloading, the load-bearing frame drives the cargo platform frame to move forward, so that the cargo platform frame exceeds the platform support, which is convenient for related material receiving equipment to dock. When the inner support moves to contact the lifting part, the cargo platform frame tilts with the sliding support as the fulcrum, thereby facilitating the sliding of materials and facilitating unloading operations.

[0019] 2. After the loading platform frame tilts, the counterweight slides accordingly, thereby driving the transmission assembly to move. The transmission assembly then pulls the pusher to move, causing the pusher to move toward the inner edge, pushing the material at the corner position to move, thereby assisting inward unloading and reducing the problem of material retention on the unloading platform.

[0020] 3. The overall design of the present invention is ingenious, and the related drive transmission structure will not affect the unloading space of the cargo platform frame. The entire unloading transmission process can be completed by a single motor drive, without the need for multiple hydraulic or motor drive structures, which can effectively avoid the problem of excessive load on the unloading platform itself.

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0032] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0034] In one embodiment;

[0035] See also Figure 1 and Figure 5 , provides an unloading platform for building construction, including a platform support 11, and a loading platform frame 12 erected on the platform support 11;

[0036] The platform support 11 is provided with a load-bearing frame 13 , and the cargo platform frame 12 is slidably mounted on the load-bearing frame 13 , and a sliding support 14 is provided between the cargo platform frame 12 and the load-bearing frame 13 for connection;

[0037] The rear edge of the cargo platform frame 12 is further provided with an inner support 15, and the platform support 11 is provided with a lifting member 16 that matches the inner support 15. When the inner support 15 moves to contact the lifting member 16, the cargo platform frame 12 tilts with the sliding support 14 as the fulcrum;

[0038] The inner edge of the cargo platform frame 12 is also provided with a pusher 17, a counterweight 18 that slides as the cargo platform frame 12 tilts, and a transmission assembly 19 connected between the pusher 17 and the counterweight 18; after the counterweight 18 slides, the pusher 17 is pulled toward the inner edge by the transmission assembly 19.

[0039] This embodiment is used for construction and unloading operations, and can be loaded onto relevant action implementation mechanisms such as lifting platforms; during operation, materials are loaded into the inner frame space of the cargo platform frame 12, and the cargo platform frame 12 is slidably mounted on the supporting frame 13. During unloading, the supporting frame 13 drives the cargo platform frame 12 to move forward, so that the cargo platform frame 12 exceeds the platform support 11, which is convenient for the relevant material receiving equipment to dock. When the inner support 15 moves to contact the lifting member 16, the cargo platform frame 12 tilts with the sliding support 14 as the fulcrum, thereby facilitating the sliding of materials and facilitating unloading operations.

[0040] After the cargo platform frame 12 tilts, as the cargo platform frame 12 tilts, the counterweight 18 slides accordingly, thereby driving the transmission component 19 to move, and the transmission component 19 then pulls the pusher 17 to move, causing the pusher 17 to move toward the inner edge, pushing the material at the corner position to move, thereby assisting inward unloading and reducing the problem of material retention on the unloading platform.

[0041] In one embodiment;

[0042] Regarding the docking method between the cargo platform frame 12 and the load-bearing frame 13, this embodiment is designed as follows:

[0043] See also Figure 1 、 Figure 2 and Figure 3 The supporting frame 13 includes a supporting outer frame 31 and a sliding rail 32 arranged on the inner edge of the supporting outer frame 31. The cargo platform frame 12 is mounted on the supporting outer frame 31. The sliding support 14 includes a front base 21 installed at the bottom of the cargo platform frame 12, a front bracket 23 arranged on the front base 21, and a steering roller 24 installed on the front bracket 23. A sliding support rod 25 is installed on the steering roller 24, and the sliding support rod 25 is supported between the sliding rails 32 on both sides.

[0044] A rotating disk 34 is installed at the rod end of the sliding support rod 25, and a sliding block 33 is sleeved on the outer edge of the rotating disk 34. The sliding block 33 is installed in the corresponding sliding rail 32. The side edge of the supporting outer frame 31 is also provided with a driving frame 35, and the inner edge of the driving frame 35 is provided with an inner driving screw 36. A driving block 37 is provided on the inner driving screw 36, and the driving block 37 is connected to the sliding block 33 on one side.

[0045] The cargo platform frame 12 is mounted on the supporting frame 13, and a front bracket 23 is provided at the front end position of the bottom plane of the cargo platform frame 12. A steering roller 24 is provided on the front bracket 23. The steering roller 24 is supported on the supporting frame 13 through a sliding support rod 25, and the sliding support rod 25 can move along the sliding track 32; a driving frame 35 is provided on the side edge of the supporting frame 13, with an internal drive screw 36 as the driving medium, and the driving block 37 is driven to move through threaded transmission, thereby driving the sliding support rod 25 to move along the sliding track 32, and then pushing the cargo platform frame 12 to move.

[0046] In one embodiment;

[0047] Regarding the tilting implementation of the cargo platform frame 12, the specific implementation structure of this embodiment is as follows:

[0048] See also Figure 1 and Figure 4 The internal support 15 includes a rear base 41 installed on the bottom of the cargo platform frame 12, a rear bracket 42 arranged on the rear base 41, and a slope block 43 installed on the rear bracket 42. The lifting member 16 includes a fixed block 44 arranged on the inner edge of the platform support 11, and a resistance block 45 installed on the fixed block 44 and connected to the slope block 43. The contact surface between the slope block 43 and the resistance block 45 is an inclined surface structure.

[0049] A rear bracket 42 is provided at the rear end of the bottom plane of the cargo platform frame 12. When it moves, its slope block 43 contacts the resistance block 45, and the slope block 43 moves along the inclined surface structure, so that the rear end of the cargo platform frame 12 is lifted, so that the cargo platform frame 12 rotates in an inclined direction with the steering roller 24 as the support point, thereby carrying out unloading processing.

[0050] In one case of this embodiment;

[0051] An electric contact connector 46 is provided between the ramp block 43 and the resistance block 45. When the ramp block 43 moves to the end of the contact surface of the resistance block 45, the electric contact connectors 46 of the two coincide with each other. The electric contact connector 46 is electrically connected to the driving end of the inner drive screw 36.

[0052] After the slope block 43 contacts the interference block 45, the slope block 43 continues to move along the inclined surface structure, so that the inclination angle of the cargo platform frame 12 increases. After the slope block 43 matches the electric contact connector 46 of the interference block 45, an electrical signal is triggered, and the electrical signal is transmitted to the driving end of the inner drive screw 36, terminating the drive of the inner drive screw 36, thereby causing the movement of the cargo platform frame 12 to stagnate. After unloading is completed, the reverse movement of the inner drive screw 36 is started again to move the cargo platform frame 12 backward, so that the cargo platform frame 12 is restored to a flat state.

[0053] In one embodiment;

[0054] Regarding the specific transmission implementation structure of the pusher 17, this embodiment is designed as follows:

[0055] See also Figure 5 and Figure 6 The pushing member 17 includes a pushing claw 55 arranged on the inner edge of the cargo platform frame 12, a sliding piece 54 installed on the pushing claw 55, and a connecting block 53 arranged on the sliding piece 54; the transmission assembly 19 includes a positioning bolt 51 arranged at the center line position inside the cargo platform frame 12, and transmission connecting rods 52 are arranged on both sides of the positioning bolt 51, and the rod ends of the transmission connecting rods 52 are respectively connected to the corresponding connecting blocks 53.

[0056] See also Figure 6 and Figure 7 The counterweight 18 includes a median slide bar 61 installed at the center line position of the cargo platform frame 12, a sleeve 62 sleeved on the median slide bar 61, and a return spring 64 wound around the median slide bar 61. A counterweight lead block 63 is provided on the sleeve 62. The other end of the return spring 64 is connected to the sleeve 62, and the sleeve 62 is further connected to the corresponding transmission link 52 through a linkage rod 65.

[0057] The main body of the pushing member 17 is the pushing claw 55, which is attached to the inner edge of the cargo platform frame 12 through the sliding piece 54 and is supported by the transmission connecting rod 52. When the cargo platform frame 12 tilts toward the front end and below, the counterweight lead block 63 also falls under the influence of gravity, so that the sliding sleeve 62 moves along the middle sliding rod 61. When the sliding sleeve 62 moves, it drives the linkage connecting rod 65 to move accordingly, thereby pulling the transmission connecting rod 52 toward the center line area to fold, and then drives the sliding piece 54 and the inner plane of the cargo platform frame 12 to move, driving the pushing claw 55 to move toward the middle area, and the pushing claw 55 then pushes the material to move, avoiding the problem of material retention on the unloading platform.

[0058] When the tilted state is restored to the flat state, the gravity effect of the counterweight lead block 63 is gradually reduced to disappear, and the reset spring 64 drives the sliding sleeve 62 to perform a reset movement along the middle slide rod 61, thereby driving the relevant transmission connecting rod 52 to move, and the pushing claw 55 is reset to the edge position of the corresponding loading platform frame 12 again.

[0059] The overall design of the present invention is ingenious, and the related drive transmission structure will not affect the unloading space of the cargo platform frame 12. The overall unloading transmission process can be completed by a single motor drive, without the need for multiple hydraulic or motor drive structures, which can effectively avoid the problem of excessive load on the unloading platform itself.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0061] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
