Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a circulatable vertical transportation device for an elevator shaft. Background Art

[0002] Vertical transportation equipment is an indispensable mechanical equipment in the construction process of modern high-rise buildings. Its main function is to transport construction materials on the ground to the high-rise construction site. At present, the most commonly used vertical transportation equipment in the construction stage are tower cranes, construction elevators, elevators, etc. The efficiency of vertical transportation directly affects the progress and construction period of the project. Tower cranes and construction elevators are mainly used in the main and secondary structure construction stages. During the facade and decoration construction stage, tower cranes and construction elevators will be dismantled. At this time, the indoor elevator has not yet reached the conditions for installation. Therefore, there is a certain vacuum period in the vertical transportation of materials. There are three common ways to deal with it:

[0003] (1) Delayed removal of tower cranes or construction elevators. Disadvantages: Delayed removal will result in the failure to construct the exterior facade of the tower crane or construction elevator on schedule, affecting the progress of the exterior facade construction; the basement roof at the tower crane location cannot be closed on time, and the basement backfill needs to reserve a driving route for tower crane removal, affecting the progress of outdoor basement backfill. At the same time, delayed removal of tower cranes or construction elevators will increase the cost of equipment use.

[0004] (2) Install the indoor elevator in advance. Disadvantages: This will greatly increase the risk of damage to the indoor elevator. In addition, since the elevator is a customized product, the inventory cycle of repair parts is long. During the repair period, the elevator cannot be operated, which affects the construction progress. At the same time, it increases the cost of elevator management and maintenance.

[0005] (3) Before dismantling the tower crane or construction elevator, transport the construction materials to the construction site in advance. Disadvantages: If the materials are brought to the site in advance, it will greatly increase the capital occupation cost and the secondary handling cost.

[0006] CN111186746A discloses a shaft construction elevator.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0039] like Figure 1 to Figure 7 As shown, the present invention provides a recyclable vertical transportation device for an elevator shaft, comprising a cage body 1, a lifting system 2 and a control system 3. A pulley 204 is fixedly installed on the top of the cage body 1; the lifting system 2 comprises a hoist 201, a wire rope 202, a first fixed pulley 203 and a pulley 204, the hoist 201 is fixedly installed on the steel beam of the elevator room, one end of the wire rope 202 is fixed on the embedded hook of the elevator room floor, and the other end passes through the pulley 204 on the top of the cage body 1, the reserved hole of the elevator room floor, and the first fixed pulley 203 at the top of the elevator room in sequence, and then is wound on the hoist 201; the control system 3 comprises a wireless controller 301 and a wireless remote controller 302, the wireless controller 301 is connected to the control circuit of the hoist 201, and the wireless remote controller 302 is used to send a control signal to the wireless controller 301 to control the operation of the hoist 201.

[0040] Furthermore, if Figure 3 As shown, the cage body 1 includes two main vertical beams 101, and the upper and lower ends of the main vertical beams 101 are respectively fixedly connected to the upper main cross beam 102 and the lower main cross beam 103 by bolts; a pulley fixing plate 104 is welded on the upper surface of the upper main cross beam 102, and a pulley 204 is bolted to the pulley fixing plate 104. The arrangement of the main vertical beams 101 provides the main supporting structure for the cage body 1, ensuring its stability and bearing capacity during vertical transportation.

[0041] Specifically, Figure 4 As shown, the lower surface of the upper main beam 102 is connected to the upper cover plate 11 by bolts, and the upper cover plate 11 includes a first longitudinal frame beam 111, a first transverse frame beam 112 and a safety protection top plate 113. The first longitudinal frame beam 111 and the first transverse frame beam 112 are connected by welding, and the four corners of the upper cover plate 11 are respectively welded with first connecting sleeves 114, and the lower surface of the upper cover plate 11 is fixed with a safety protection top plate 113 by bolts. The design of the upper cover plate 11 not only enhances the structural strength of the cage body 1, but also provides necessary safety protection for operators and materials through the safety protection top plate 113.

[0042] Furthermore, the upper surface of the lower main beam 103 is connected with a lower bottom plate 12 by bolts, and the lower bottom plate 12 includes a second longitudinal frame beam 121, a second transverse frame beam 122 and a safety protection bottom plate 123. The second longitudinal frame beam 121 and the second transverse frame beam 122 are connected by welding, and the four corners of the lower bottom plate 12 are respectively welded with second connecting sleeves 124, and the outer surface of the second connecting sleeve 124 is welded with a rubber wheel fixing plate 125. The design of the lower bottom plate 12 echoes the upper cover plate 11, further enhancing the overall structural stability of the cage body 1, and providing support for the installation of the directional rubber wheel 126.

[0043] Specifically, Figure 7 As shown, a directional rubber wheel 126 is installed on the rubber wheel fixing plate 125, and the directional rubber wheels 126 are connected by springs 127. The directional rubber wheels 126 fix the cage body 1 inside the well through the adjustment of the springs 127. During the lifting process of the cage body 1, the directional rubber wheels 126 rotate along the well wall to improve the stability of the cage body 1 during the lifting process. The setting of the spring 127 can effectively buffer the vibration that may be generated by the cage body 1 during operation, reduce the impact on the inner wall of the well, and extend the service life of the device.

[0044] Furthermore, if Figure 5 As shown, the inner surface of the main vertical beam 101 is connected with a side plate 13 by bolts, and the side plate 13 includes a vertical frame beam 131, a third horizontal frame beam 132, a safety protection side plate 133 and a safety door booster 14; the vertical frame beam 131 and the third horizontal frame beam 132 are connected by bolts, and the inner surface of the side plate 13 is fixed with a safety protection side plate 133 by bolts. The design of the side plate 13 not only provides separation and protection for the internal space of the cage body 1, but also provides a structural basis for the installation of the safety door booster 14.

[0045] Specifically, Figure 6 As shown, the safety door booster device 14 includes a safety door slide 141, a gravity block slide 142, a gravity block 143, a second fixed pulley 144 and a transmission rope 145; the safety door slide 141 is welded to the vertical frame beam 131 near the safety door, the gravity block slide 142 is welded to the third horizontal frame beam 132 near the safety door, one end of the transmission rope 145 is connected to the gravity block 143, and the other end is connected to the booster terminal 153 at the lower side of the safety door by passing through the second fixed pulley 144. The design of the safety door booster device 14 utilizes the gravity of the gravity block 143, and through the cooperation of the transmission rope 145 and the second fixed pulley 144, provides assistance for the opening and closing of the safety door 15, reduces the labor intensity of the operator, and improves the convenience and safety of operation.

[0046] Furthermore, the safety door 15 includes a door panel 151, a power-assisting handle 152 and a power-assisting terminal 153. The safety door 15 is installed in the safety door slide slot 141. The power-assisting handle 152 is installed on the outer side of the middle of the door panel 151, and the power-assisting terminals 153 are installed on both sides of the lower part of the door panel 151. The design of the safety door 15 provides necessary safety protection for the entry and exit of the cage body 1. The setting of the power-assisting handle 152 makes it easy for the operator to open and close the safety door 15, further improving the convenience of operation.

[0047] Preferably, the load-bearing components and maintenance components of the cage body 1 are connected by bolts. This connection method not only facilitates the rapid installation and disassembly of the device, but also can adapt to the construction requirements of narrow spaces, avoids the use of large mechanical equipment during installation and disassembly, saves equipment and labor costs, and facilitates rapid turnover.

[0048] Preferably, the longitudinal and transverse beams of the upper cover plate 11 and the lower bottom plate 12 of the cage body 1 are connected by welding. The welding connection method can effectively enhance the structural strength of the upper cover plate 11 and the lower bottom plate 12, and ensure the stability and bearing capacity of the cage body 1 during vertical transportation.

[0049] When in use, the wireless remote controller 302 sends a start signal, and the wireless controller 301 installed on the hoist 201 starts the hoist 201 after receiving the start signal. The hoist 201 provides power through the wire rope 202 to make the cage body 1 rise or fall along the shaft. The directional rubber wheels 126 installed at the four corners of the lower part of the cage body 1 fix the cage body 1 inside the shaft through the adjustment of the spring 127. During the lifting process, the directional rubber wheels 126 rotate along the shaft wall to improve the stability of the cage body 1. This device uses the existing elevator hooks, elevator installation beams and reserved holes in the elevator room. There is no need for additional modification and construction of the elevator shaft and the elevator room, which speeds up the installation and reduces the difficulty of installation. The entire cage body 1 adopts a partially split structure. Except for the longitudinal and transverse beams of the upper cover plate 11 and the lower base plate 12, which are connected by welding, other load-bearing components and maintenance components are connected by bolts. This design not only increases the integrity of the cage body 1, facilitating quick installation and disassembly, but also adapts to the construction requirements of narrow spaces, avoids the use of large mechanical equipment during installation and disassembly, saves equipment and labor costs, and facilitates quick turnover.
