Description

Technical Field

[0001] The utility model relates to the field of building engineering material transportation, and particularly relates to a discharging platform for building engineering. Background Technique

[0002] During the construction of a building, as the building floors increase continuously, building materials need to be transported to the discharging platform by means of equipment such as a crane. The discharging platform is usually directly fixed on the outer side of the floor and inserted into the inner side of the embedded steel bar structure, and material handling can be carried out normally by using the discharging platform.

[0003] The existing discharging platforms generally use high-strength steel beams to be erected on the outer side of the building floor, and then a steel plate is arranged on the steel beam to form a discharging area, and guardrails are arranged around the discharging area to ensure the safety of personnel. However, due to the certain thickness of the steel beam, a step is formed between it and the ground. In order to enable the trolley to transport materials smoothly, a transition plate is usually laid obliquely between the steel beam and the building floor, and workers complete the uphill and downhill of the trolley with the help of the transition plate. However, when the materials are heavy, their inertia is very large, and workers need to apply a great deal of pulling force or pushing force during the uphill and downhill processes of the trolley, which is rather laborious, invisibly increasing the labor intensity of workers and there are also potential safety hazards.

[0013] Preferably, the maximum stroke of the piston rod of the cylinder makes the gear rotation angle 90°.

[0014] Compared with the prior art, the utility model provides a material unloading platform for construction engineering, which has the following beneficial effects:

[0015] (1)For the unloading platform proposed in this application, the transition plate provided between the building floor and the carrier plate is in an inclined state in the initial state. When the materials carried by the trolley are relatively light, they can be directly transferred through this transition plate. When the materials are relatively heavy, first drive the lifting block to move upward at the bottom of the steel beam frame. During the upward movement of the lifting block, drive the transition plate to rotate. Eventually, the transition plate and the carrier plate are in the same horizontal plane. At this time, the wheels of the trolley move onto the transition plate, and the lifting block moves downward to lower the horizontally placed carrier plate to the building floor. During the whole process, the worker only needs to assist the trolley to control it to always stay on the carrier plate. When the trolley climbs the slope, the wheels directly press on the carrier plate to make the carrier plate in a horizontal state, and then the trolley is transported to the same height as the carrier plate through the lifting block. Subsequently, it is relatively labor-saving for the worker to push the trolley. By using the unloading platform proposed in this application, the trolley can avoid the trouble of being operated by workers when going up and down the slope, but directly uses mechanical lifting instead, which provides convenience for workers.

[0016] (2)In addition, the entire unloading platform is also relatively flexible in use. Workers can adjust the state of the transition plate according to their own needs. If it is not necessary to convert the transition plate into a horizontal state for lifting, then the transition plate can also cooperate with the baffle and the limit plate to keep the horizontal sliding rod fixed. In this way, the transition plate can always be in an inclined state, and workers can complete the transportation of light materials by themselves. Description of the Drawings

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0027] This embodiment proposes a discharge platform for building engineering, as Figures 1 to 7 shown, including a steel beam frame 1 erected in the building construction area. The steel beam frame 1 is fixed to the edge of the high-rise building by implanting ground anchors. After installation, the protruding area is fixed with a guardrail 4. A dense net can also be installed on the guardrail 4. The front end of the steel beam frame 1 is provided with a front protection net 3 to improve safety. Four wire rope connection rings 2 are distributed on both sides of the steel beam frame 1. While the entire steel beam frame 1 is anchored and installed, it is also fixed by means of wire ropes. One end of the wire rope is connected to the wire rope connection ring 2, and the other end is fixed to the upper layer of the building floor, forming a lifting effect on the entire steel beam frame 1 through the wire rope.

[0028] The top of the steel beam frame 1 is located inside the guardrail 4 and a loading plate 6 is set to form a working area. The crane puts the building materials on the loading plate 6. After the construction workers push the trolley on the loading plate 6, they command the crane driver to place the building materials on the trolley, and then push the trolley to remove it from the loading plate 6 and send it to the work site. Since the steel beam frame 1 itself is relatively thick, a step will be formed between the loading plate 6 and the ground. In order to enable the trolley to move smoothly to the top of the loading plate 6, a transition plate 7 is tilted between the loading plate 6 and the ground to form a slope. When the material transported by the trolley is relatively light, the workers can complete the up and down slope of the trolley with the help of the transition plate 7. However, when the material is relatively heavy, its inertia is very large. When the trolley moves downward on the transition plate 7, it is necessary to control the trolley with force to avoid the trolley from going downhill too fast. When the garbage generated during the construction process is transported to the ground through the platform, the workers need to push the trolley full of garbage onto the loading plate 6. When the trolley climbs the slope on the transition plate 7, the workers are even more laborious.

[0029] In order to improve the above situation, two "cross" shaped lifting blocks 9 are symmetrically arranged at the bottom of the steel beam frame 1. The lifting block 9 is slidably installed with a horizontal sliding rod 8 along the length direction of the steel beam frame 1. One end of the horizontal sliding rod 8 extends toward the direction of the transition plate 7 and is hingedly connected to it (it is best to provide a torsion spring at the connection between the horizontal sliding rod 8 and the transition plate 7). The end away from the transition plate 7 passes through the outside of the lifting block 9 and is fixedly connected to the limit plate 11. A spring 12 is also sleeved on the circumferential surface of the horizontal sliding rod 8. One end of the spring 12 is connected to the lifting block 9, and the other end is connected to the limit plate 11. The spring 12 is initially in a free state; the lifting block 9 is respectively provided with guide columns 15 and threaded rods 16 on both sides perpendicular to the axial direction of the horizontal sliding rod 8. The top of the guide column 15 is fixedly connected to the bottom of the steel beam frame 1, and the bottom end is connected to the connecting plate 17. The top of the threaded rod 16 is connected to the output end of the motor fixed to the bottom of the steel beam frame 1, and the bottom end is connected to the connecting plate 17 to maintain rotation. In the initial state, the transition plate 7 is in Figure 2In the state shown, when the trolley is in the no-load state, it is pushed along the transition plate 7 to above the carrier plate 6. When the trolley is fully loaded with building materials and moves to the connection between the carrier plate 6 and the transition plate 7, first start the motor to drive the threaded rod 16 to rotate. The lifting block 9 moves upward under the action of the threaded rod 16 and the guide post 15. Since the upper end of the transition plate 7 is connected to the steel beam frame 1 in a sliding manner (the upper end of the transition plate 7 slides vertically relative to the steel beam frame 1, not shown in the figure), the horizontal sliding rod 8 will slide relative to the lifting block 9 towards the transition plate 7, and the spring 12 is gradually stretched. When the lifting block 9 rises to the maximum height, at this time the transition plate 7 is horizontal and at the same height as the carrier plate 6. It should be noted that in order not to affect the normal lifting of the lifting block 9, an avoidance groove 13 is also provided at the bottom of the steel beam frame 1 corresponding to the movement path of the horizontal sliding rod 8 to prevent the steel beam frame 1 from interfering with the movement of the lifting block 9. After the worker pushes the trolley so that the wheels move above the transition plate 7, then reverse-start the motor to drive the lifting block 9 to move downward. After the lifting block 9 returns to the initial position, the bottom of the transition plate 7 contacts the ground, and the worker can easily push the trolley away from the transition plate 7. At this time, the transition plate 7 has a tendency to rotate and reset under the action of the torsion spring, and can be fully reset under the action of the spring 12.

[0030] Similarly, when the trolley loaded with garbage is pushed from the building floor to the carrier plate 6, the wheels first apply a force to the transition plate 7. The top end of the transition plate 7 slides downward vertically relative to the steel beam frame 1, and the two horizontal sliding rods 8 slide towards the transition plate 7 until the transition plate 7 moves to the horizontal state. At this time, start the motor to drive the lifting block 9 to move upward. After the transition plate 7 rises to the same level as the carrier plate 6, the worker easily pushes the trolley onto the carrier plate 6, and then reverse-start the motor to drive the lifting block 9 to reset. During the reset process, the transition plate 7 returns to the initial position again through the reaction force of the torsion spring and the spring 12.

[0031] In addition, during the construction process, there are many types of materials to be transported, and the weights of the materials are inconsistent. When the material to be transferred is heavy, the transition plate 7 can be driven to perform the above actions to complete the uphill and downhill of the trolley. When the material to be transferred is light, the worker can directly move the trolley by means of the inclined transition plate 7. Therefore, the transition plate 7 also needs to be able to remain fixed in an inclined state. To achieve this purpose, a back plate 14 is fixed at the bottom of the steel beam frame 1 near the two limit plates 11. A base 18 is integrally formed and connected to the middle of the side of the back plate 14 facing away from the limit plate 11. A rack 19 is slidably mounted on the base 18 along its length direction. The rack 19 is driven to perform a linear motion by a cylinder 20 mounted on the base 18. A gear 21 meshing with the rack 19 is rotatably mounted on the surface of the back plate 14. The central axis of the gear 21 penetrates through to the other side along the thickness direction of the back plate 14 and is fixedly sleeved with a first sprocket 22. Shaft rods are rotatably mounted at both ends of the side of the back plate 14 facing the limit plate 11. A second sprocket 24 is sleeved on each shaft rod. The two second sprockets 24 and the first sprocket 22 are connected by a sleeved chain 23 to establish a transmission. The two shaft rods extend towards the inside of the corresponding limit plate 11, and after extending into the inside of the corresponding limit plate 11, they are connected to a baffle 25. The inside of the limit plate 11 is in a cavity shape, and its top is flush with the top of the lifting block 9 through a notch. A through groove 26 is opened in the vertical direction on the side of the limit plate 11 facing the second sprocket 24 for the shaft rod to slide. The bottom of the limit plate 11 has another notch with a shape adapted to that of the baffle 25. The two notches at the top and bottom of the limit plate 11 and the through groove 26 are connected. The length of the baffle 25 is the same as the inner diameter of the limit plate 11. When the baffle 25 is in a vertical state, it will not affect the movement of the lifting block 9. The transition plate 7 can be rotated and lifted. When the cylinder 20 acts to drive the rack 19 to mesh with the gear 21, the two baffles 25 will rotate synchronously. When the piston rod of the cylinder 20 extends to the limit state, the meshing of the rack 19 and the gear 21 can exactly make the gear 21 rotate 90°. At this time, the two baffles 25 form a block inside the limit plate 11, and the horizontal sliding rod 8 remains fixed relative to the lifting block 9. In this state, the transition plate 7 can always be in an inclined state.
