Description

Technical Field

[0001] The utility model relates to the technical field of stair assembling construction, in particular to a trolley system for assembling prefabricated stair slabs. Background Art

[0002] Subway stations are places with a high concentration of people, and are usually equipped with multiple entrances and exits for people to enter and exit, which is convenient for reducing the pressure of people entering and exiting. At the same time, different entrances and exits lead to multiple directions around the subway station, which can also improve people's travel efficiency, reduce detours in and out of the station, and improve the convenience of riding. In the prior art, station entrances and exits include vertical elevators, escalators, and fixed stairs. Vertical elevators can provide convenience for people with limited mobility, but their carrying capacity is limited and their efficiency is relatively low. Escalators and fixed stairs can accommodate a large number of people and have high traffic efficiency. Escalators can also reduce people's fatigue from climbing, but they are significantly affected by the power supply situation and cannot be used as fixed stairs when the power is off. Therefore, fixed stairs and escalators are set in combination.

[0003] In the prior art, fixed steps, also known as stairs, are generally constructed step by step, which has low efficiency and is difficult to construct in some narrow dark excavation spaces.

[0004] It can be seen that there is still room for improvement in the existing stair construction, and it should be optimized to improve the convenience and efficiency of stair construction. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Utility Model Content

[0005] In order to overcome at least one of the defects mentioned above, the utility model proposes a trolley system for assembling prefabricated stair slabs, by which the stairs are transported and installed through the assembly trolley, thereby improving the efficiency of stair assembly construction and the convenience of stair construction.

[0006] In order to achieve the above purpose, the assembly trolley system disclosed in the utility model can adopt the following technical solutions:

[0007] Trolley system for assembly of prefabricated stair slabs, including:

[0008] The trolley is used to carry the prefabricated stair slabs and transport them to the installation location. The walking mechanism of the trolley includes front wheels, middle wheels and rear wheels, and the trolley carries the prefabricated stair slabs by lifting the bearing plate assembly;

[0009] Support piles, a number of which are used to temporarily support the prefabricated stair slabs, and the trolley loads the prefabricated stair slabs from the support piles;

[0010] The driving assembly includes a driver, which is connected to the trolley through a traction rope and is used to control the trolley to slide from an initial position on the top of the installation base to the installation position, and is used to pull the trolley back to the initial position.

[0011] The above-disclosed trolley system uses the trolley as a transport mechanism to obtain the prefabricated stair panels at a fixed point and transport the prefabricated stair panels to the installation position for assembly. It has high overall efficiency, quick and simple operation, and saves a lot of manpower and material resources. It can also smoothly carry out operations in some construction spaces that are relatively narrow and inconvenient for large equipment to enter and multiple people to collaborate.

[0012] Furthermore, in the present invention, the trolley structure can be constructed in a variety of forms, which are not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the trolley includes a frame, the frame includes two opposite side frames, a middle column is arranged in the middle of the side frames, and the two side frames are connected and fixed by connecting crossbeams; the front wheels and the rear wheels are respectively arranged at the front and rear ends of the frame, and the middle wheels are arranged at the lower end of the middle column. When such a scheme is adopted, the side frames can be made of square steel welding, and the number of connecting crossbeams is not limited. In order to ensure the overall strength of the frame, they can be arranged in multiple places so as not to affect the travel of the trolley and the picking and placement of the stair prefabricated panels.

[0013] Furthermore, the structure of the side frame is optimized and the following feasible option is proposed: the side frame includes a ladder frame, the bottom crossbeam length of the side frame is greater than the top crossbeam length, and the front column of the side frame is inclined and parallel to the middle column. When such a solution is adopted, the inclination angles of the front column and the rear column of the side frame can be set according to the slope of the installation surface, and generally the front column can be kept vertical and the rear column can be kept perpendicular to the ramp surface.

[0014] Furthermore, in order to enhance the supporting strength of the side frame, the structure of the side frame can be enhanced, which can be achieved in a variety of ways, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: a plurality of support ribs are arranged on the side frame, and the support ribs are obliquely arranged between the top cross beam and the bottom cross beam to form a triangular support structure. When such a solution is adopted, the top and bottom ends of the support ribs can be connected to the top cross beam and the bottom cross beam respectively through connecting bolts.

[0015] Furthermore, the lifting and loading plate assembly used in the utility model can be constructed in various forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the lifting and loading plate assembly includes a set of lifting plates, the number of which is at least two and they are lifted and lowered along the front column and the middle column respectively, and the lifting plates are connected to a transverse moving assembly for fixing the stair prefabricated plate. When such a solution is adopted, the lifting plates are used to connect, cooperate and fix the front end and the rear end of the stair prefabricated plate.

[0016] Furthermore, in order to make the process of taking and adjusting the stair prefabricated parts smoother, an optimization is made here and one of the feasible options is proposed: a lifting track is formed at the front column and the middle column, and the lifting plate is matched to the lifting track; and a lifting device is provided on the upper part of the frame, and the lifting device drives the lifting plate to move up and down. When such a solution is adopted, the lifting device can use an electric hoist to drive the lifting plate to rise and fall synchronously, thereby lifting the stair prefabricated plate or lowering the stair prefabricated plate.

[0017] Furthermore, in the present invention, the sliding structure of the lifting plate can be constructed in a variety of forms, which are not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: parallel columns are provided at the front column and the middle column, and sliding gaps are formed between the parallel column and the front column, and between the parallel column and the middle column respectively, and are used to set the lifting plate; the end of the lifting plate is connected with an I-shaped sliding head and is clamped in the sliding gap. When such a solution is adopted, the parallel column can be made of the same square steel as the front column and the middle column, and is welded and fixed to the top crossbeam and the bottom crossbeam, or a detachable structure is adopted in some solutions.

[0018] Furthermore, the transverse moving assembly can adopt a variety of structures, which are not limited to the only one. Here, we optimize and propose one feasible option: the transverse moving assembly includes a receiving plate that reciprocates along the length direction of the lifting plate, and a plurality of hanging parts are arranged on the receiving plate to connect and fix the stair prefabricated plate. When such a solution is adopted, the hanging parts are rigid parts, and they can bear weight after connecting the stair prefabricated plate.

[0019] Furthermore, in the present invention, the receiving plate is slidably matched with the lifting plate, and a transverse movement driver is provided at the lifting plate to drive the receiving plate to move.

[0020] Furthermore, the hoisting member includes a sling, and a screw rod is provided at the lower end of the sling; when connecting the stair prefabricated panel, the screw rod is matched with the threaded sleeve of the stair prefabricated panel.
