Description

Technical Field

[0001] This invention relates to the field of construction hoist technology, and in particular to a multifunctional intelligent chimney tower construction hoist. Background Technology

[0002] Chimneys and cooling towers (collectively referred to as chimneys and towers) in thermal power plants are typical tall structures, characterized by long construction periods, great heights, and complex working environments. Vertical transportation equipment is crucial for ensuring personnel commuting and material flow during chimney and tower construction. Currently, standard SC-type construction hoists are commonly used on construction sites to handle the main vertical transportation tasks. These devices typically only have basic personnel and cargo carrying functions, and their relatively fixed cabin structures cannot adapt to the diverse and frequently changing operational needs during chimney and tower construction.

[0003] However, with the increasing complexity of construction processes, existing construction hoists have revealed significant shortcomings, including limited functionality and low space utilization. Specifically, chimney and tower construction frequently involves the vertical transport of heavy or elongated equipment such as long steel pipes and motors. Because the cabin of a traditional hoist is an enclosed space, it cannot accommodate oversized or overweight cargo, often requiring construction companies to rent tower cranes or winches for external hoisting. This not only results in numerous pieces of equipment on the construction site, occupying valuable workspace, but also increases the cost of expensive equipment rental and maintenance. Current technology lacks an integrated system that can fully utilize the external space of the cabin (such as the top, bottom, or outer side) to simultaneously hoist large materials or assist in the transport of bulk materials without affecting the commuting of personnel inside.

[0004] In summary, existing single-function construction hoists can no longer meet the diverse operational requirements of efficient, integrated, and safe operation in chimney and tower construction. There is an urgent need to develop a multi-functional intelligent construction hoist that integrates lifting, bulk material transportation, and personnel carrying, and can safely conform to the chimney and tower working surface. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional intelligent chimney and tower construction hoist, which solves the problems mentioned in the background art, such as the existing construction hoists having limited functions, lack of expansion capabilities for hoisting heavy objects using external space, low space utilization, and difficulty in adapting to the complex and diverse vertical transportation needs in chimney and tower construction, resulting in low construction efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional intelligent chimney and tower construction hoist, comprising a standard section set on the ground, two cars symmetrically arranged on both sides of the standard section, each car having a car door symmetrically arranged on both sides, and a hoist assembly set on the top of the car; The crane assembly includes a support platform fixedly connected to the top of the car, a support column installed on the support platform, a telescopic column rotatably connected to the support column, and a hook provided at the end of the telescopic column; The bottom of the car is reserved with a bottom working area, which is used to configure auxiliary transportation components according to construction needs.

[0007] Preferably, two symmetrically arranged limiting plates are fixedly connected to one side of the car. Each of the two limiting plates has a limiting hole, and a limiting pin for limiting is inserted into the two limiting holes. A hanger is provided between the two limiting plates, and a lifting ring is provided at the top of the hanger, which is hung on a hook; The bottom of the hanger is provided with a bearing frame, the upper middle part of the hanger is provided with a ring lock, and the lower middle part of the hanger is provided with support pins on both sides. The support pins are inserted into the slotted ear plates installed at the bottom of the car.

[0008] Preferably, the ring lock includes a support plate mounted on a hanger, one end of which is hinged to an arc-shaped plate, and the other end of the support plate is engaged with the other end of the arc-shaped plate.

[0009] Preferably, the telescopic column includes a primary telescopic column, a secondary telescopic column, and a tertiary telescopic column.

[0010] Preferably, the auxiliary transport component includes a hopper installed on the bottom of the car, with a feed inlet at the top of the hopper, a discharge outlet at the bottom of the hopper, and an adjusting arc plate hinged to the outside of the discharge outlet; The bottom of the car has a channel corresponding to the feed inlet, and a movable plate is installed above the channel.

[0011] Preferably, two guide wheels are provided at the top of the car, and each guide wheel is provided with a flexible traction member. One end of the flexible traction member is connected to the bottom of the car door, and the other end is connected to a counterweight block slidably connected to one side of the car. The two guide wheels are arranged sequentially along the transmission path of the flexible traction member, and the rotation axes of the two guide wheels are not horizontal, so that when the flexible traction member passes the guide wheels, it can transition from a vertical state at the center of the car door to an inclined state pointing towards the counterweight side.

[0012] Preferably, a power supply lever is provided at the top of the inner wall of the car, a transmission rod is hinged to the lower part of the power supply lever, a control lever is hinged to the bottom end of the transmission rod, one end of the control lever is hinged to the inner wall of the car, and the control lever is configured as a manual operating handle. When the control lever is manually moved, the power supply lever is moved through the transmission rod to mechanically shut off the main power supply.

[0013] Preferably, the bottom sides of the car are hinged with flaps, which are configured to overlap the flat bridge of the chimney after being flipped open.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up the crane components and using a support platform in conjunction with multi-stage telescopic columns, it is convenient to use the external space on the top of the car to independently hoist large construction components such as motors and long steel pipes. At the same time, the hydraulically driven telescopic structure can ensure flexible coverage of the hoisting area during operation and shrink the external size when idle, solving the problem that traditional enclosed cars cannot transport special materials, improving the overall efficiency of vertical transportation and reducing the cost of additional tower crane rental.

[0015] Second, by setting up a steel-reinforced support hanger, during use, the hanger and the car are rigidly fixed both vertically by the top lifting ring and the bottom support pin inserted into the slotted ear plate. This ensures that the hanger remains absolutely stable during the lifting and lowering of the car. At the same time, the ring lock assembly can forcibly lock loose steel bar bundles, completely eliminating the hidden dangers of long strip materials swinging and colliding inside the chimney and the risk of core scattering, thus improving the safety and stability of special building material transportation.

[0016] Third, by setting up auxiliary transportation components, the bottom working area is reserved with a combination of interfaces and detachable hoppers, which facilitates flexible switching between manned mode and concrete transportation mode according to the needs of the construction stage. At the same time, the adjustment arc plate at the bottom of the hopper can ensure that the concrete is accurately guided to the construction chute and automatically unloaded by gravity, which solves the problems of fixed functions and difficulty in bulk material transfer of existing equipment, and improves the equipment's adaptability to complex construction conditions.

[0017] Fourth, by setting up a mechanical power-off mechanism and a flap assembly, and using a purely mechanical linkage consisting of a control rod, a transmission rod, and a power supply rod, operators can manually cut off the main power supply at a lower position without having to climb, ensuring emergency safety in case of an emergency. At the same time, the flap assembly adopts a flip-over overlapping method, which effectively fills the irregular gap between the rectangular car and the curved smoke tower wall, improving the safety of personnel entering and exiting and the convenience of operation.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-8 As shown, the present invention provides a technical solution: a multi-functional intelligent chimney tower construction hoist, including a standard section 1 set on the ground, two cars 2 symmetrically arranged on both sides of the standard section 1, each car 2 having a car door symmetrically arranged on both sides, and a hoist assembly set on the top of the car 2; The crane assembly includes a support platform 211 fixedly connected to the top of the car, a support column 212 mounted on the support platform 211, a telescopic column 213 rotatably connected to the support column 212, and a hook 214 provided at the end of the telescopic column 213; the telescopic column 213 and the hook 214 are driven by an integrated hydraulic system or an electric winch mechanism. The bottom of the car 2 is reserved with a bottom working area, which is used to configure auxiliary transportation components according to construction needs.

[0022] The support platform 211 is a base fixed to the top of the car 2. It is used to distribute the concentrated load generated by the crane, prevent local deformation of the top of the car 2, and ensure structural strength. The support column 212 is used to raise the working reference plane of the crane, so that the telescopic boom 213 is higher than the guardrail or other facilities on the top of the car 2, avoiding operation interference and providing a better working view. The telescopic column 213 provides variable amplitude cantilever support, which can be telescopic and rotated. When extended, it can cover the hoisting area outside the car 2. When retracted, it can reduce the overall size of the machine, making it easier for the elevator to operate in narrow shafts and providing good passability. The hook 214 can be used to directly lift ordinary goods or as a mounting point to connect a special steel bar hanger.

[0023] Furthermore, two symmetrically arranged limiting plates 221 are fixedly connected to one side of the car 2. Each limiting plate 221 has a limiting hole 222, and a limiting pin for limiting is inserted into the two limiting holes 222. A hanger 223 is provided between the two limit plates 221, and a lifting ring 224 is provided on the top of the hanger 223. The lifting ring 224 is hung on the hook 214. The bottom of the hanger 223 is provided with a bearing frame 225, the upper middle part of the hanger 223 is provided with a ring lock 226, and the lower middle part of the hanger 223 is provided with support pins 227 on both sides. The support pins 227 are inserted into the slotted ear plates 228 installed at the bottom of the car 2, and the two form a rigid fit.

[0024] The limiting plate 221 forms a lateral guide groove for the installation of the hanger 223, playing a guiding and positioning role during the installation or disassembly of the hanger 223, preventing the hanger from swinging left and right. The limiting pin is inserted into the limiting plate 221 to temporarily lock the hanger in the idle state and prevent it from falling off. The hanger 223 is the main skeleton for transporting steel bars, providing a dedicated space to accommodate long strip materials, replacing the unsafe simple binding method of steel wire rope. The lifting ring 224 is the stress point at the top of the hanger 223, which cooperates with the universal hook 214 to achieve rapid lifting. The quick-connection system allows for tool-free installation of the hanger 223. The load-bearing frame 225 can withstand the vertical weight of the steel reinforcement bundles, preventing them from slipping off from the bottom. The ring lock 226 can forcibly gather loose steel reinforcement bundles, preventing them from "pulling out" or scattering and injuring people during transportation. The support pin 227 serves as the lower anchor point, guiding the hanger 223 to connect with the bottom of the car 2. The slotted ear plate 228 ensures that the hanger 223 and the car 2 become a rigid whole during transportation, completely eliminating the safety hazard of the suspended load swaying in the air.

[0025] Furthermore, the ring lock 226 includes a support plate 2261 mounted on the hanger 223. One end of the support plate 2261 is hinged to an arc-shaped plate 2262, and the other end of the support plate 2261 is engaged with the other end of the arc-shaped plate 2262. A locking pin or latch is provided at the engagement point to prevent accidental opening.

[0026] The support plate 2261 and the arc plate 2262 together form an opening and closing mechanism. The arc design fits the shape of the steel bar bundle, and the hinged structure facilitates quick loading and unloading of materials, improving work efficiency.

[0027] Furthermore, the telescopic column 213 includes a primary telescopic column, a secondary telescopic column, and a tertiary telescopic column, with each level of telescopic column being driven by a built-in hydraulic cylinder.

[0028] Furthermore, the auxiliary transport component includes a hopper 311 installed on the bottom surface of the car 2. The hopper 311 is detachably fixed to the beam frame at the bottom of the car 2 by a bolt group. The top of the hopper 311 is provided with a feed inlet 312, and the bottom of the hopper 311 is provided with a discharge outlet 313. An adjustment arc plate 314 is hinged to the outside of the discharge outlet 313. The bottom of the car 2 has a channel corresponding to the feed inlet 312, and a movable plate is provided above the channel. The movable plate is preferably a slide gate valve or a sliding gate structure.

[0029] The hopper 311 is specifically designed for the storage and transportation of fluid or bulk materials such as concrete, soil, and mortar. The inlet 312 connects to the opening of the bottom plate of the car 2, allowing for direct feeding from inside the car 2, which is convenient to operate. The outlet 313 can automatically unload by gravity without additional power. The adjusting arc plate 314 is a guide plate hinged at the outlet 313, which can adjust the angle and range of the discharge to prevent concrete splashing and accurately guide the flow to the chute.

[0030] Furthermore, two guide wheels 411 are provided at the top of the car 2. Each guide wheel 411 is equipped with a flexible traction element 412, such as a steel wire rope. One end of the flexible traction element 412 is connected to the bottom of the car door, and the other end is connected to a counterweight block 413 that is slidably connected to one side of the car 2. The two guide wheels 411 are arranged sequentially along the transmission path of the flexible traction element 412, and the rotation axis of the two guide wheels 411 is not horizontal, so that when the flexible traction element 412 passes through the guide wheels 411, it can transition from a vertical state at the center of the car door to an inclined state pointing towards the counterweight side.

[0031] The guide wheel 411 can change the transmission direction of the flexible traction component 412. Its rotation axis is not horizontal, which can adapt to the angle change of the traction component from vertical to inclined, so that the wire rope is always located in the center of the wheel groove, greatly reducing wear and preventing derailment. The flexible traction component 412 is used to connect the car door and the counterweight 413 to transmit the pulling force. The counterweight 413 can balance the weight of the car door, reduce the opening resistance, and realize easy manual or electric opening.

[0032] Furthermore, a power supply lever 511 is installed at the top of the inner wall of the car 2. The top of the power supply lever 511 is connected to the air switch or knife switch handle in the main power supply box. A transmission rod 512 is hinged to the bottom of the power supply lever 511. A control rod 513 is hinged to the bottom of the transmission rod 512. One end of the control rod 513 is hinged to the inner wall of the car 2. The control rod 513 is configured as a manual operating handle and is located at a height inside the car 2 that is convenient for personnel to operate. When the control rod 513 is manually moved, the power supply lever 511 is moved through the transmission rod 512 to mechanically shut off the main power supply.

[0033] The power lever 511 is used to turn off the main power switch. The transmission rod 512 is an intermediate transmission component that can transmit displacement and force. Connecting the power lever 511, the control rod 513 works on the principle of leverage, allowing operators to cut off the main power by hand from the ground or the car floor without having to climb. Moreover, the purely mechanical structure remains effective in the event of an electrical fault, providing safety assurance.

[0034] Furthermore, the bottom sides of the car 2 are hinged with flaps 23. The flaps 23 are configured to overlap the flat bridge of the chimney after being flipped open. During the operation of the car, the flaps 23 are flipped upward to store and lock.

[0035] Working principle: First, the construction personnel enter the elevator car 2 and start the elevator. The elevator car 2 moves up or down along the standard section 1. Second, when the elevator car 2 reaches the designated chimney tower working level and stops, the flaps 23 on both sides of the bottom of the elevator car flip outwards. The flaps 23 overlap the flat bridge of the chimney tower, filling the gap between the rectangular elevator car 2 and the arc-shaped tower wall, and establishing a safe passage. Third, the elevator car door is opened. During the opening process, the motor drives the guide wheel 411 to rotate, which drives the flexible traction component 412 to move on the guide wheel 411, thereby driving the elevator car door to rise and open. Fourth, if an electrical fault occurs during operation or parking, or if an emergency power cut is required, the operator does not need to climb up. He can directly manually move the control lever 513 at the bottom inside the elevator car. Fifth, the control lever 513 rotates around the hinge point, using the lever principle to push the transmission rod 512 upwards. The transmission rod 512 then drives the power supply lever 511 at the top to move, mechanically forcibly pulling down the switch handle of the main power supply box, realizing the physical power cut-off of the entire machine.

[0036] When materials need to be hoisted, the first step is to rotate and extend the telescopic column 213 on the top of the car to adjust the position of the hook 214 so that it covers the object to be hoisted outside the car. The second step is for the operator to hang the material to be hoisted on the hook 214. The third step is to retract the telescopic column 213 or raise the hook to lift the object off the ground or between floors, and rotate the telescopic column 213 to keep it suspended. The fourth step is to drive the car 2 vertically to the target floor, and operate the telescopic column 213 again to place the object on the target working surface to complete the independent hoisting operation.

[0037] When it is necessary to transport steel bars, the first step is to place the steel bars in the bearing frame 225 at the bottom of the hanger 223. The second step is to fix the steel bars on the hanger 223 with the ring lock 226. The third step is to operate the top crane and hook the hook 214 onto the lifting ring 224 at the top of the hanger. The fourth step is to fine-tune the height of the hook so that the hanger 223 sinks until the support pin 227 at its bottom is precisely inserted into the pre-welded slotted ear plate 228 at the bottom of the car. The fifth step is to place the hanger 223 between the two limiting plates 221 on the side of the support platform 211 and fix it to the side of the car 2 with the limiting pin 222.

[0038] When bulk materials need to be transported, the first step is to fix the hopper 311 under the bottom beam of the car 2 at the reserved interface in the working area at the bottom of the car 2 using bolts. The second step is to remove the movable plate on the floor inside the car 2 to expose the feed port 312. The third step is for the construction personnel to pour concrete or mortar into the hopper 311 directly through the opening in the floor inside the car 2. The fourth step is for the car 2 to run to the floor to be poured, and the construction personnel to adjust the angle of the adjusting arc plate 314 at the bottom of the hopper so that it is aligned with the external construction chute or handcart. The fifth step is to open the valve of the discharge port 313, and the material will automatically slide out along the adjusting arc plate 314 under the action of gravity, completing the unloading.
