Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, and in particular to a transportation and unloading platform for deep-buried subway station projects. Background Technology

[0002] The transport and unloading platform for deep-buried subway stations is a temporary operating facility designed specifically to solve the problem of vertical material transportation during the construction of deep-buried subway stations. The main function of the platform is to serve as a vertical transportation hub for material turnover, connecting the ground and the construction floors, enabling the rapid transfer of bulk materials such as steel bars and formwork, significantly improving transportation efficiency and reducing manual handling costs.

[0003] Because of the confined space in the deep-buried station, traditional unloading platforms require workers to manually move and stack materials. Due to the intermittent nature of vertical transportation (such as the lifting interval of the crane) and the narrow operating space of the platform, workers need to frequently adjust their positions and repeat bending and moving actions, which can easily lead to fatigue accumulation. Especially in continuous operation, the efficiency of manual unloading is significantly affected by the fluctuation of physical strength, and there are safety hazards such as material slippage and personnel falling, making it difficult to balance efficiency and safety. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a transportation and unloading platform for deep-buried subway station projects. It solves the problem that traditional material transportation methods are insufficient to meet the requirements of efficient and safe unloading during the construction of deep-buried subway stations due to the large depth of the foundation pit and limited working space.

[0005] According to an embodiment of this utility model, a transport and unloading platform for deep-buried subway station projects includes guide rails, a base, a lifting assembly, and a receiving platform. Multiple guide rails are vertically arranged, forming a lifting channel between them. A side plate surrounds the top of the base, and one side of the top of the base has an opening with a door for opening or closing. A sliding plate is slidably mounted on the top of the base, and a storage platform is detachably mounted on the sliding plate. A driving assembly for driving the sliding plate to slide is mounted on the base. The lifting assembly is located on the top of the guide rails and is used to drive the base to rise or fall along the guide rails. The receiving platform is located on one side of the bottom of the guide rails. The top of the receiving platform facing the guide rails has a receiving groove for the sliding plate to extend into. Lifting mechanisms for lifting the storage platform are also provided on both sides of the receiving platform.

[0006] Compared with the prior art, this utility model has the following advantages: by placing the material on the platform, the lifting component releases the base, and the base is guided by the guide rail to descend to a predetermined height. Then, the drive component drives the slide plate into the receiving slot on the predetermined receiving platform. At this time, the lifting mechanism lifts the platform to complete the unloading. The entire process does not require workers to handle the material. Based on the original space range, fast and safe unloading can be achieved, thus satisfying the requirement of efficient and safe unloading in a confined space.

[0007] Furthermore, the lifting mechanism is an electric push rod, and several slots are provided on both sides of the receiving groove. Each slot is equipped with an electric push rod, and the output end of the electric push rod is vertically upward.

[0008] Furthermore, each lifting mechanism has a positioning rod at its output end, and both ends of the bottom of the platform have slots that correspond one-to-one with the positioning rods for insertion.

[0009] Furthermore, the top of the skateboard is equipped with a limiting post, and the bottom of the shelf is provided with a limiting groove for the limiting post to be inserted.

[0010] Furthermore, the drive assembly includes a lead screw and a motor. The base has a groove for the slide plate to slide in, and a mounting groove is provided on the side wall of the groove. The lead screw is horizontally and rotatably mounted in the mounting groove and is threadedly connected to the slide plate. The base is also provided with a motor for driving the lead screw to rotate.

[0011] Furthermore, the lifting assembly includes: a pull rope, a mounting box mounted on the top of the guide rail, the bottom of the mounting box communicating with the lifting channel, an opening on one side of the mounting box, a winch fixedly mounted on the top of the mounting box, one end of the pull rope being fixedly connected to the top of the side plate, and the other end of the pull rope being connected to the output end of the winch.

[0012] Furthermore, the enclosed door is a retractable door. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a transport and unloading platform for deep-buried subway station engineering, including guide rails 1, base 2, lifting components, and receiving platform 6. Multiple guide rails 1 are vertically arranged, forming a lifting channel between them. The top of the base 2 is surrounded by a side plate 3, and one side of the top of the base 2 has an opening with a door for opening or closing. A slide plate 4 is slidably mounted on the top of the base 2, and a storage platform 5 is detachably mounted on the slide plate 4. The base 2 is equipped with a driving component for sliding the slide plate 4. The lifting component is located on the top of the guide rails 1 and is used to drive the base 2 to rise or fall along the guide rails 1. The receiving platform 6 is located on one side of the bottom of the guide rails 1. The top of the receiving platform 6 facing the guide rails 1 has a receiving groove for the slide plate 4 to extend into. Lifting mechanisms 7 for lifting the storage platform 5 are also provided on both sides of the receiving platform. Specifically, the top of the base 2 near the opening has a groove for the slide plate 4 to slide in, and the width of the storage platform 5 is greater than the width of the slide plate 4, so that both ends of the storage platform 5 completely cover the slide plate 4. In this embodiment, multiple guide rails 1 are vertically installed in the pit, and the lifting assembly is installed on the ground. By opening the closed door, the material to be transported is placed on the platform 5, and then the lifting assembly is activated. After the lifting assembly lowers the base 2 to a predetermined position, a receiving platform 6 is provided at the predetermined position. It should be noted that the number of receiving platforms 6 can be arranged on one side of the guide rails 1 as needed. By activating the drive assembly, the drive assembly drives the slide plate 4 to move towards the receiving platform 6, so that the slide plate 4 extends into the receiving groove. At this time, the lifting mechanism 7 is activated, and the output end of the lifting mechanism 7 lifts, driving the platform 5 to lift, so that the platform 5 is separated from the slide plate 4. At this time, the slide plate 4 retracts into the base 2 under the action of the drive assembly. At this time, the lifting mechanism 7 resets, so that the platform 5 is placed on the receiving platform 6. Preferably, the bottom of the platform 5 is provided with rollers, and the top of the corresponding slide plate 4 is provided with a clearance groove for the rollers to be accommodated, so as to facilitate unloading it on the receiving platform 6 and transporting it to the predetermined position. This device places materials on the platform 5, lowers it to a predetermined height, and then drives the sliding plate 4 into the receiving slot. At this point, the lifting mechanism 7 lifts the platform 5, completing the unloading process. Throughout the entire process, workers do not need to handle the materials; unloading can be achieved quickly and safely within the existing space. Preferably, several platforms 5 are configured.

[0021] like Figure 3 As shown, the lifting mechanism 7 is further configured as an electric push rod. Several slots are provided on both sides of the receiving groove, and an electric push rod is installed in each slot. The output end of the electric push rod points vertically upwards. In this embodiment, an electric push rod is used as the lifting mechanism 7. Two slots are respectively provided on both sides of the receiving groove on the receiving platform 6. The electric push rods are fixed in the slots. When all four electric push rods are activated simultaneously, they lift the platform 5 above it, causing it to detach from the sliding plate 4, thus achieving the purpose of unloading. Similarly, the electric push rod can also be a cylinder or a hydraulic cylinder, etc.

[0022] like Figure 3 As shown, furthermore, each lifting mechanism 7 has a positioning rod 8 at its output end, and both ends of the bottom of the platform 5 have slots corresponding to the positioning rods 8 for insertion. By controlling the movement distance of the slide plate 4 through the drive assembly, specifically by using a PLC programmable logic controller, the slots on the slide plate 4 are aligned with the positioning rods 8, so that the platform 5 is lifted only after the positioning rods 8 are inserted into the slots, thereby maintaining the stability of the platform 5.

[0023] like Figures 4 to 5 As shown, the top of the slide plate 4 is provided with a limiting post 9, and the bottom of the platform 5 is provided with a limiting groove for the limiting post 9 to be inserted. The platform 5 is detachable by the cooperation of the limiting post 9 and the limiting groove. At the same time, due to the presence of the limiting post 9, the platform 5 cannot be displaced in the horizontal direction, thus avoiding the platform 5 from slipping off the slide plate 4 and causing a safety accident. The platform 5 can be displaced in the vertical direction, which also facilitates the lifting mechanism 7 to lift it for the purpose of unloading.

[0024] like Figure 4 As shown, the drive assembly further includes a lead screw 10 and a motor 11. The base 2 has a groove for the slide plate 4 to slide in, and a mounting groove is provided on the side wall of the groove. The lead screw 10 is horizontally and rotatably mounted in the mounting groove and is threadedly connected to the slide plate 4. The base 2 is also equipped with a motor 11 for driving the lead screw 10 to rotate. When the slide plate 4 is driven into the receiving groove on the receiving platform 6, the motor 11 is started, which drives the lead screw 10 to rotate. The lead screw 10 drives the slide plate 4 to move along its length, so that one end of it extends into the receiving groove, facilitating subsequent unloading operations.

[0025] like Figure 1 and Figure 2As shown, the lifting assembly further includes: a pull rope 12; a mounting box 13 is mounted on the top of the guide rail 1; the bottom of the mounting box 13 communicates with the lifting channel; one side of the mounting box 13 is open; a winch 14 is fixedly mounted on the top of the mounting box 13; one end of the pull rope 12 is fixedly connected to the top of the side plate 3; and the other end of the pull rope 12 is connected to the output end of the winch 14. The components below the mounting box 13 are buried below ground level. In this embodiment, there are four pull ropes 12. One end of each pull rope 12 is located at one of the four corners of the concave side plate 3. The other ends of the four pull ropes 12 are combined into a single strand and wound by the winch 14. When the winch 14 operates, it releases the four pull ropes 12, and the base 2 descends to a predetermined height under gravity, thus changing the horizontal height of the base 2. Preferably, guide wheels can be provided on the outer walls of the base 2 and the side plate 3 to make the lifting of the base 2 and the side plate 3 smoother.

[0026] like Figure 1 As shown, the closing door is a telescopic door 15. To cope with the confined space, a telescopic door 15 is provided at the opening at the top of the base 2. Specifically, a storage groove is provided on the side plate 3 near the opening, and one end of the telescopic door 15 is fixed in the storage groove. The free end of the telescopic door 15 can slide along the opening to open or close the opening. Preferably, a guide groove is provided at the top of the sliding plate 4 for the sliding of the retractable door. After the telescopic door 15 closes the opening at the top of the base 2, it restricts the sliding of the sliding plate 4.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
