DETAILED DESCRIPTION

[0028] This embodiment provides a material discharging platform with a material transfer function, such as Figure 1-Figure 4 As shown, it includes a main platform 1, two supporting steel beams 2, a support frame and a transport part 3. The side of the main platform 1 facing the building is connected to the floor of the building through the two supporting steel beams 2; one end of the support frame is arranged on the floor, and the other end extends into the main platform 1. A roller slide is provided on the upper surface of the support frame, and the transport part 3 is placed on the roller slide. The transport part 3 is used to place materials, and the transport part 3 can slide along the slide between the main platform 1 and the floor to transport materials.

[0029] The present invention sets a passage between the main platform 1 and the floor slab, abandons the traditional manual transportation method, and uses the transport part 3 to slide back and forth on the passage to complete the material transportation between the floor slab and the main platform 1, and then the conventional lifting equipment transports the transport part 3 together with the material from the main platform 1. Similarly, the lifting equipment can transport the transport part 3 and the material to the main platform 1, and then move them to the floor slab along the passage.

[0030] Optionally, the main platform 1 includes a base plate 4, a main guardrail circle and 5 side guardrail circles. The base plate 4 is square, the main guardrail circle is vertical and surrounds three sides of the base plate 4 to prevent materials on the base plate 4 from falling; the side guardrail 5 circles are inclined and surround the outside of the main guardrail circle to provide further protection.

[0031] Further optionally, the bottom of the main guardrail circle is fixedly connected to the edge of the base plate 4, and the main guardrail circle includes two side guardrails 5 and a front guardrail 6, and a side guardrail 5 is respectively connected to both sides of the front guardrail 6, and the side guardrail 5 is perpendicular to the front guardrail 6. The front guardrail 6 is arranged on the side of the base plate 4 away from the floor and opposite to the floor, and the side guardrails 5 are arranged on the other two sides of the base plate 4.

[0032] Further optionally, the side guardrail 5 includes two inclined fences 7, the fences 7 are located outside the corresponding side guardrail 5, the bottom of the fence 7 is fixedly connected to the side of the bottom plate 4, the top of the fence 7 points to the outside of the bottom plate 4, and the top of the fence 7 is lower than the top of the corresponding side guardrail 5. Preferably, the main guardrail is a solid metal plate, and the side guardrail 5 is a metal mesh.

[0033] In the traditional technology, materials are transported to the platform by manpower, and then the materials are manually tied, and then transported to the ground by the lifting device. The work efficiency is very low, and the construction workers need to enter the platform repeatedly, resulting in uneven and continuously changing force on the platform. In the present invention, inside the floor, the materials are loaded on the transport part 3 and fixed. The transport part 3 slides directly into the main platform 1 along the channel composed of the support frame and the roller slide. The construction workers do not need to carry them back and forth, and the construction efficiency is improved. In the present invention, the lifting device directly lifts the transport part 3 and the materials, and the transport part 3 is added compared to the traditional technology. Therefore, 5 circles of side guardrails are added on the outside of the main guardrail circle to add a layer of protection and improve safety. The 5 circles of side guardrails are metal mesh plates to prevent the weight of the main platform 1 from increasing too much.

[0034] The support and connection form of the two supporting steel beams 2 to the main platform 1, and the connection form of the supporting steel beams 2 to the floor slab are the same as those of the existing cantilever unloading platform.

[0036] The upper surface of the first bracket 8 is provided with a first slideway 11, the upper surface of the second bracket 9 is provided with a second slideway 12, and the upper surface of the third bracket 10 is provided with a third slideway 13. The direction from the floor to the main platform 1 is the length direction of the support frame.

[0037] Further optionally, the first slideway 11 includes a plurality of rollers 14 arranged in sequence and first track rods 15 at both ends of the rollers, the first track rods 15 are parallel to the length direction of the support frame, the two ends of the rollers are rotatably connected to the first track rods 15 at both ends, the surface of the rollers 14 is covered with rubber sleeves, when the transport part 3 passes through the first slideway 11, the lower surface of the transport part 3 contacts the rubber sleeve of the rollers to protect the rollers and the transport part 3, the movement of the transport part 3 drives the rollers to rotate, and the rotation of the rollers in turn promotes the movement of the transport part 3;

[0038] A first track groove 18 is provided on the vertical outer side surface of the first track rod 15 . The first track groove 18 is recessed into the first slideway 11 . The wheels 31 on both sides of the transport part 3 can be respectively inserted into the corresponding first track groove 18 and roll along the first track groove 18 .

[0039] Further optionally, the first bracket 8 is a traditional frame bracket, that is, a plurality of groups of vertical support rods 22 at the bottom support a horizontal frame at the top, and the first slide 11 is placed on the horizontal frame 23;

[0040] Two second track grooves 19 are provided on the horizontal frame, and the bottoms of the first track rods 15 on both sides of the first slideway 11 are inserted into the corresponding second track grooves 19, so that the first slideway 11 can move along the second track grooves 19;

[0041] A first lifting device 24 is also provided in the middle of the first bracket 8. The first lifting device 24 is fixed on the ground and can lift or lower the horizontal frame of the first bracket 8 to adapt to different inclination angles of the second bracket 9.

[0042] The vertical support rod 22 of the first bracket 8 is a retractable sleeve structure. After the height of the support rod is adjusted according to the height of the first bracket 8, the height of the support rod is fixed by inserting and tightening the screws to fix the first bracket 8.

[0043] Optionally, the structure of the second slide 12 is the same as that of the first slide 11, that is, the second slide 12 includes a plurality of rollers arranged in sequence and second track rods 16 at both ends of the rollers, the second track rods 16 are parallel to the length direction of the support frame, the two ends of the rollers are rotatably connected to the second track rods 16 at both sides, and the surface of the rollers is covered with a rubber sleeve;

[0044] A third track groove 20 is provided on the vertical outer side surface of the second track rod 16 , and the third track groove 20 is recessed into the second slideway 12 . The wheels 31 on both sides of the transport part 3 can be respectively inserted into the corresponding third track groove 20 and roll along the third track groove 20 .

[0045] Further optionally, the second bracket 9 is also a traditional frame bracket, that is, a plurality of groups of vertical support rods at the bottom support the horizontal frame at the top, and the second slide 12 is fixed on the horizontal frame of the second bracket 9;

[0046] A second lifting device 25 is provided below one end of the second bracket 9 close to the first bracket 8. The second lifting device 25 is fixed on the ground and can adjust the height of one end of the horizontal frame of the second bracket 9 close to the first bracket 8, so that the second bracket 9 presents different inclination angles to adapt to the transportation of materials of different weights.

[0047] The vertical support rod of the second bracket 9 is a retractable sleeve structure. After the height of the support rod is adjusted according to the height of a corresponding part of the second bracket 9, the height of the support rod is fixed by inserting and tightening the screws to support the second bracket 9.

[0048] In order to facilitate the sliding of the transport part 3 on the support frame, an inclined second bracket 9 is designed in the present invention. The end (front end) of the second bracket 9 close to the first bracket 8 is relatively high, and the end (rear end) close to the third bracket 10 is relatively low. The rear end of the second bracket 9 is fixedly connected to the third bracket 10. The transport part 3 is stably placed on the horizontal first bracket 8, and materials are loaded and unloaded. After the materials are loaded, they slide down along the second bracket 9 inclined downward to the third bracket 10. This form of transportation that relies on the transport part 3 and the gravity of the materials themselves saves time and effort. When the transport part 3 carries a lot of materials, the rollers under the transport part 3 are pressed, so that the friction force increases and affects the movement of the transport part 3. The height of the front end of the second bracket 9 is appropriately raised to increase the inclination angle of the second bracket 9, so as to promote the smooth sliding of the transport part 3 to the third bracket 10.

[0049] The rear end of the second bracket 9 is fixed, and the up and down position of the front end is only adjusted by the second lifting device 25. After the front end position is determined, the length (i.e., height) of each support rod of the second bracket 9 is adaptively adjusted. The support rod is an upper and lower sleeve rod structure. When the upper part is pulled upward out of the lower part, the support rod is lengthened and raised. When the upper part is retracted downward into the lower part, the support rod is shortened and lowered. The overlapping part of the upper part and the lower part is provided with a corresponding number of through holes, which is convenient for inserting screws or bolts to fix the relative position of the upper part and the lower part.

[0050] When the horizontal frame of the second bracket 9 changes its tilt angle, the vertical position and horizontal position of the front end of the second bracket 9 will change, and the first bracket 8 needs to change its position in coordination with the front end of the second bracket 9. When the front end of the second bracket 9 rises, it also moves away from the first bracket 8 in the horizontal direction. The first lifting device 24 raises the horizontal frame of the first bracket 8, and the support rod of the first bracket 8 also rises adaptively and continues to support the first bracket 8. Then, the two first track rods 15 of the first slide 11 move toward the second bracket 9 along the corresponding second track grooves 19 respectively, until the first track grooves 18 can dock with the corresponding third track grooves 20, to ensure that the wheels 31 on both sides of the transport part 3 do not derail and can slide smoothly from the first bracket 8 to the second bracket 9. A plurality of through holes are provided between the first track rods 15 and the corresponding second track grooves 19. When the relative positions of the two are determined, a vertical pin rod is inserted into the corresponding through holes of the two at this time to fix the horizontal positions of the two.

[0051] When the front end of the second bracket 9 needs to be lowered, it also needs to be close to the first bracket 8 in the horizontal direction. The first lifting device 24 lowers the horizontal frame of the first bracket 8, and the support rod of the first bracket 8 is also adaptively lowered and continues to support the first bracket 8. Then, the two first track rods 15 of the first slide 11 move along the corresponding second track grooves 19 in the direction away from the second bracket 9, and then the pin rods are used to fix the horizontal positions of the first track rods 15 and the corresponding second track grooves 19; the second lifting device 25 is used to lower the height of the front end of the second bracket 9 until the third track groove 20 can dock with the corresponding first track groove 18 to ensure that the wheels 31 on both sides of the transport part 3 do not derail.

[0052] Optionally, the structure of the third slide 13 is the same as that of the first slide 11, that is, the third slide 13 includes a plurality of rollers arranged in sequence and third track rods 17 at both ends of the rollers, the third track rods 17 are parallel to the length direction of the support frame, the two ends of the rollers are rotatably connected to the third track rods 17 at both sides, and the surface of the rollers is covered with a rubber sleeve;

[0053] A fourth track groove 21 is provided on the vertical outer side of the third track rod 17. The fourth track groove 21 is recessed toward the inside of the third slideway 13. The wheels 31 on both sides of the transport part 3 can be respectively inserted into the corresponding fourth track groove 21 and roll along the fourth track groove 21.

[0054] The third bracket 10 is a square horizontal frame, and the third slideway 13 is placed on the horizontal frame.

[0055] Further optionally, a first limiting portion 26 is provided at one end (rear end) of the third bracket 10 close to the front guardrail 6, and the first limiting portion 26 includes a vertical limiting plate and a plurality of horizontally placed springs, the limiting plate is fixed at the rear end of the third bracket 10 and protrudes upward; the spring is a hard spring and is evenly arranged on the side of the limiting plate facing the front end of the third bracket 10, the transport part 3 slides toward the front guardrail 6 on the third slide 13, and hits the spring of the limiting plate, and the spring stops the transport part 3 during the compression and resetting process, so that the transport part 3 finally stops smoothly at the rear end of the third bracket 10.

[0056] Optionally, two fixed pulleys 28 are provided at the front end of the first bracket 8 (the end away from the second bracket 9), the central axis of the fixed pulley 28 is horizontal, so that the wheel surfaces on both sides are vertical, and a winding machine 29 is provided below the first bracket 8, and the winding machine 29 passes through two ropes around the corresponding fixed pulleys 28 and then connects to the front end of the transport part 3;

[0057] When the transport part 3 slides from the floor to the main platform 1, the front section of the transport part 3 is not connected to the rope; when the transport part 3 needs to return to the first bracket 8, the rope can be manually connected at the front end of the transport part 3, and the winding machine 29 can be started to pull the transport part 3 back to the first bracket 8.

[0058] Further optionally, the front end of the first bracket 8 is provided with a second limiting portion 27, which is located between the fixed pulley 28 and the transport portion 3 and is used to limit the position of the transport portion 3 on the first bracket 8. The second limiting portion 27 can be in various forms, such as a vertical plate.

[0059] Optionally, the transport unit 3 includes a body 30, four wheels 31, a protective net 32 ​​and a detachable protective plate 33. The body 30 is a square plate. The four wheels 31 are respectively arranged near the four top corners of the body 30. The protective plate 33 is vertical and the bottom is detachably connected to the side of the end of the body 30 facing the main platform 1 to prevent the material from tilting toward the front of the slide when the transport unit 3 slides on the support frame after loading the material; the protective net 32 ​​can cover the surface of the material to assist in fixing the position of the material.

[0060] Further optionally, two wheels 31 are respectively provided on the outer sides of the two sides of the body 30 parallel to the length direction of the support frame, and the central axis of the wheel 31 is vertical, so that the wheel surface of the wheel 31 is horizontal, and the wheel surface can contact the vertical outer side surfaces of the above-mentioned each track rod, and can roll along the first track groove 18, the third track groove 20 and the fourth track groove 21 respectively, thereby driving the body 30 to move along the support frame.

[0061] Further optionally, the protective net 32 ​​includes a mesh surface 34 and two fixing rods, the mesh surface 34 is made of mesh ropes woven in a horizontal and vertical direction, and the two ends of the mesh surface 34 are respectively connected to a fixing rod, and the fixing rod is horizontal and perpendicular to the length direction of the support frame; the first fixing rod 35 is arranged at one end of the vehicle body 30 where the protective plate 33 is set, and the first fixing rod 35 is between the protective plate 33 and the material, and the second fixing rod 36 is detachably arranged on the side of the vehicle body 30 opposite to the protective plate 33.

[0062] There are many options for connecting the two fixing rods with the vehicle body 30. For example, two semicircular mounting rings 39 are provided on the front side of the vehicle body 30. The opening of the mounting rings 39 faces upward. The base of the mounting rings 39 is hinged with a semicircular buckle. The parts of the second fixing rod 36 close to both ends are placed in the corresponding mounting rings 39. The buckles are buckled with the corresponding mounting rings 39 to form a circle. The mounting rings 39 and the buckles are then connected and fixed by bolts. A mounting groove is provided on the rear side of the vehicle body 30. The mounting groove is sunk into the vehicle body 30. Only a hollow strip 38 is left on the upper surface of the vehicle body 30. The first fixing rod 35 is inserted into the mounting groove. The two ends of the first fixing rod 35 are respectively screwed with protrusions with a diameter larger than the mounting groove to prevent the first fixing rod 35 from escaping from the mounting groove. The protective net 32 ​​extends out of the vehicle body 30 from the hollow strip 38. The above two installation methods are relatively simple and relatively firm, and prevent the two fixing rods from detaching from the vehicle body 30 when the hoisting device hoists the transport part 3. The protective net can be set longer to cover different amounts of materials. If the material is not much, the second fixing rod can wrap the excess protective net around its own rod body and fix it with the mounting ring and buckle.

[0063] When in use, the transport unit 3 stops on the first bracket 8, the first fixing rod 35 has been installed in advance at the rear end of the vehicle body 30, the protective plate 33 is also installed on the side of the rear end of the vehicle body 30, and the protective net 32 ​​can be placed on the protective plate 33 without affecting the loading of the vehicle body 30. The first bracket 8 is on the floor inside the building, and materials can be loaded manually or mechanically. After the materials are loaded on the vehicle body 30, the second fixing rod 36 is pulled from the rear end of the vehicle body 30 to the front end of the vehicle body 30 and installed at the front end of the vehicle body 30, so that the protective net 32 ​​covers the materials, plays a role in fixing the materials and preventing them from falling. A lifting connection part is installed at the center of the top of the protective net 32, and the lifting connection part connects the two ends of the first fixing rod 35 and the two ends of the second fixing rod 36 through a steel cable.

[0064] Then, according to the weight of the loaded material, the inclination angle of the second slideway 12 is reasonably adjusted so that the transport part 3 can slide down smoothly. The transport part 3 can be pushed manually, and the transport part 3 slides down on the second bracket 9 by its own gravity, and when it slides to the horizontal third bracket 10, it gradually slows down, and finally the outer side surface of the protective plate 33 hits the spring of the first limit part 26, and stops moving.

[0065] Preferably, a limiting rod 37 is provided in the main platform 1, and the two ends of the limiting rod 37 are respectively connected to the inner side surfaces of the two side guardrails 5, the limiting rod 37 is perpendicular to the length direction of the support frame, the limiting rod 37 and the middle part of the spring are on the same vertical plane, the height of the limiting rod 37 is not higher than the height of the protective plate 33, and a rubber pad is provided on the side of the limiting rod 37 facing the building. When the outer side of the protective plate 33 hits the first limiting part 26, the upper part of the protective plate 33 also contacts the limiting rod 37, so that the upper and bottom parts of the protective plate 33 are limited, so as to avoid limiting the bottom part of the protective plate 33 alone when the sliding speed of the vehicle body 30 is too high, which causes the upper part of the transport unit 3 to tip over to the front guardrail 6, and ensures that the transport unit 3 is stably docked.

[0066] The hoisting device moves to above the transport part 3, and the hook of the hoisting device is connected to the hoisting connection part. Under the action of the steel cable, the transport part 3 and the material are hoisted together.

[0067] When it is necessary to hoist materials from the ground to the main platform 1, remove the protective plate 33 on the ground, install the materials on the vehicle body 30, fix the materials with two fixing rods and the protective net 32, install the steel cable and the lifting connection part, and the lifting device will lift the materials and the transport part 3 and put them on the third bracket 10 of the main platform 1. Manually remove the connection between the lifting device and the lifting connection part, then pass the rope of the winder 29 around the fixed pulley 28, and then connect it to the front end of the vehicle body 30. The winder 29 pulls the transport part 3 toward the first bracket 8 through the rope (removing the protective plate 33 can reduce the deadweight of the transport part 3) until the front end of the vehicle body 30 contacts the second limit part 27, and stops pulling. At this time, the transport part 3 and the material are on the horizontal first bracket 8 and will not move easily. Release the second fixing rod 36 and the protective net 32, and move the material manually or mechanically.

[0068] The unloading platform of the present invention can significantly reduce the number of times construction workers enter and exit the main platform 1 , which is beneficial to the stability of the main platform 1 .
