Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hoisting technology, specifically relating to a base frame fence for a construction hoist and the construction hoist itself. Background Technology
[0002] Construction hoists, as essential specialized equipment for transporting personnel and materials to higher ground on construction sites, typically consist of a hoist cage and a base frame enclosure. In existing technology, the hoist cage and base frame enclosure are mostly designed as a fixed pair, meaning a specific model of cage must be used with a corresponding specification of base frame enclosure. The base frame enclosure primarily defines the cage's running track, provides safety protection, and serves as a load-bearing foundation. Its structural dimensions are usually designed based on the cage's external dimensions and operational requirements, and the two must be strictly matched during installation. While this design can meet the stability and safety requirements of general construction scenarios, the overall structure is relatively fixed and lacks necessary adaptability and flexibility.
[0003] However, existing base frame enclosures generally have limitations in adapting to multiple types of hoisting cages, and their structural design also leads to inconvenience for personnel and material access. Because different hoisting cage models differ in size, load capacity, and operating methods, traditional base frame enclosures often only serve a single cage specification, failing to achieve universal installation and application. Furthermore, to meet structural strength requirements, base frame enclosures are typically designed as fixed rigid frame structures, resulting in limited operating space and low efficiency when personnel carry tools or materials in and out. This deficiency means that in actual construction, if the hoisting cage model needs to be changed or adjusted, the entire base frame enclosure system must be replaced simultaneously, significantly increasing equipment costs and storage difficulties, and reducing the utilization efficiency and deployment flexibility of construction equipment.

[0018] Explanation of reference numerals in the attached figures Detailed Implementation
[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0020] The following description, with reference to the accompanying drawings, describes a base frame railing and a construction hoist according to the present invention. The first aspect of the present invention provides a base frame railing 6 for a construction hoist, as shown in the accompanying drawings. Figure 1As shown, the system includes a swing gate assembly and a fence assembly. The swing gate assembly includes a swing gate fence panel 61 forming a ground access opening and a swing gate 65 installed at the ground access opening. The fence assembly and the swing gate assembly together form an accommodating space with an open top. The fence assembly includes a fixed fence panel 64 and an extended fence panel 63 detachably connected to the fixed fence panel 64. The swing gate assembly includes a swing gate fence panel 61 with a ground access opening and a swing gate 65. The swing gate 65 is connected to the swing gate fence panel 61 by hinges to ensure convenient passage. When the swing gate 65 is opened, it can form a passage for personnel and materials to enter and exit. The fence assembly is formed by combining the fixed fence panel 64 and the detachable extended fence panel 63 to create an accommodating space with an open top. The extended fence panel 63 is quickly assembled and disassembled from the fixed fence panel 64 by bolts or a plug-in mechanism, allowing the size of the entire fence to be flexibly adjusted according to construction needs.
[0021] The detachable nature of the extended fence panel 63 allows the base frame fence 6 to adapt to different working conditions, improving its adaptability to complex construction sites; the prefabricated structure not only reduces the space occupied during transportation but also reduces the difficulty of on-site installation; the design of the swing door 65 and the swing door fence panel 61 achieves a balance between safe isolation and efficient passage; the open structure at the top naturally forms the elevator operating channel, and the enclosed space not only ensures personnel safety but also provides stable protection for equipment operation, achieving a comprehensive improvement in safety performance, ease of operation, and engineering adaptability.
[0022] In some embodiments, the fence assembly includes a first fixed fence plate 641, a second fixed fence plate 642, and a third fixed fence plate 643. One end of the first fixed fence plate 641 and one end of the second fixed fence plate 642 are respectively connected to both ends of the third fixed fence plate 643. The other ends of the first fixed fence plate 641 and the other ends of the second fixed fence plate 642 are detachably connected to the extended fence plate 63. Specifically, the third fixed fence plate 643 serves as the core load-bearing unit, with both ends connected to one end of the first fixed fence plate 641 and the second fixed fence plate 642, forming a stable main frame. The other ends of the first fixed fence plate 641 and the second fixed fence plate 642 are detachably connected to the extended fence plate 63 via bolts or pins, making the extended fence plate 63 an extension of the frame, forming a complete enclosure structure, which significantly improves the engineering adaptability and installation efficiency of the equipment. The main frame, consisting of three fixed fence panels 64, provides a rigid support foundation, ensuring the overall structural stability. The detachable extended fence panel 63 module allows for quick adjustment of the fence size during construction without replacing the entire frame. This reduces warehousing and transportation costs, minimizes on-site installation time, and maintains the integrity and safety of the fence system, effectively adapting to the different needs of various construction site conditions.
[0023] In some embodiments, two extension fence panels 63 are used, connected to the first fixed fence panel 641 and the second fixed fence panel 642 respectively. Each of the first fixed fence panel 641 and the second fixed fence panel 642 is connected to one extension fence panel 63. The two extension fence panels 63, as symmetrically distributed extension modules, form a symmetrical enclosure structure extension, allowing each extension fence panel 63 to be installed or removed independently, and together with the main frame, constitute a complete protective system. The detachable structure allows for dispersed packaging during transportation, effectively reducing the overall size and space occupied. During installation and maintenance, workers can independently disassemble and reassemble the extension fence without affecting the overall structural stability, reducing maintenance workload while maintaining the overall rigidity and safety performance of the fence system.
[0024] In some implementations, such as Figure 2 As shown, the swing door assembly also includes a swing door locking component 62 and a swing door transmission component 66, which is used to drive the swing door locking component 62 to unlock the swing door 65.
[0025] like Figure 3 As shown, the swing door assembly also includes a stop plate 661, a stop tube 662, a first rotating shaft 663, a second rotating shaft 664, and a third rotating shaft 665. The stop plate 661 is connected to the swing door drive component 66 via the first rotating shaft 663 and can rotate relative to the swing door drive component 66 via the first rotating shaft 663. The stop tube 662 and the swing door locking component 62 are both connected to the third rotating shaft 665 and can rotate via the third rotating shaft 665. The third rotating shaft 665 is fixed to the mounting plate 666 of the swing door assembly. The swing door drive component 66 is connected to the mounting plate 666 via the second rotating shaft 664 and can rotate via the second rotating shaft 664. A return spring 667 is also provided on the second rotating shaft 664. Figure 4 As shown, in the initial state, the swing door transmission component 66 is in a horizontal state, and the stop plate 661 will jam the stop tube 662, preventing the swing door locking component 62 from rotating around the third rotation axis 665. The swing door locking component 62 is located in front of the limiting shaft 68, which is connected to the swing door 65. At this time, the swing door 65 cannot be opened because the limiting shaft 68 is blocked by the swing door locking component 62, so the swing door 65 is in a locked state.
[0026] When the cage device 5 descends from the height into the base frame enclosure 6, as Figure 5As shown, the contact iron installed on the cage device 5 or the tower climbing platform 7 contacts the swing door transmission component 66, causing the swing door transmission component 66 to rotate clockwise around the second rotating shaft 664, thereby causing the stop plate 661 to rotate. At the same time, the return spring 667 deforms and stores elastic potential energy. At this time, the stop plate 661 no longer jams the stop tube 662, and the stop tube 662 and the swing door locking component 62 can rotate around the third rotating shaft 665, so that the swing door locking component 62 no longer blocks the limiting shaft 68. The swing door 65 can drive the limiting shaft 68 to rotate around the door hinge to open the swing door 65. The limiting shaft 68 can pass over the swing door locking component 62, and the swing door 65 can open and close normally. The swing door 65 is in the unlocked state.
[0027] When the hoisting cage 5 moves upward away from the base frame fence 6, the contact iron loses contact with the swing door transmission component 66. The swing door transmission component 66 loses external force, and the return spring 667 releases its elastic potential energy. Under the action of the return spring 667, the swing door transmission component 66 returns to its initial position, driving the stop plate 661 to rotate and the swing door locking component 62 to return to its initial locked position, thus locking the swing door 65 again. The swing door transmission component 66 allows unlocking without direct contact with the swing door locking component 62, simplifying the opening process and avoiding the risk of misoperation. The mechanical interlocking characteristics of the swing door locking component 62 ensure that the swing door 65 remains locked in the non-triggered state, effectively preventing accidental opening due to vibration or accidental collision. This satisfies the operational needs for rapid passage while enhancing the safety protection level of the fence system, achieving a balance between safety and work efficiency.
[0028] In some embodiments, the swing door drive component 66 is detachably connected to the swing door fence panel 61, which has multiple mounting portions 67 for installing the swing door drive component 66. These mounting portions 67 are typically threaded mounting holes or quick-connect slots, distributed at different heights on the fence panel. The swing door drive component 66 has a corresponding connection interface at its bottom, allowing for quick engagement with any mounting portion 67 via bolts or snap-fit locking. This enables the swing door drive component 66 to be flexibly moved and installed between different positions on the fence panel without the need for special tools. The multiple mounting portions 67 allow the swing door drive component 66 to be installed in suitable locations according to on-site operating habits or traffic flow requirements. Furthermore, the detachable structure allows the swing door drive component 66 to be replaced independently when damaged, without replacing the entire swing door fence panel 61, reducing maintenance costs and downtime.
[0029] The second aspect of this utility model provides a construction hoist, such as... Figure 6As shown, the system includes a cage system and a base frame enclosure 6 as described above. The cage system enters and exits the receiving space through a top opening. The top opening structure of the base frame enclosure 6 is aligned with the lifting path of the cage system, allowing the cage system to vertically penetrate the receiving space formed by the enclosure. The detachable extended enclosure panels 63 in the enclosure assembly are bolted together to adjust the overall size to accommodate different cage system sizes. The swing door assembly controls the opening and closing of the ground access opening through a linkage mechanism between the swing door drive component 66 and the swing door locking component 62. The swing door drive component 66 can be flexibly arranged according to the position of the installation part 67. The top opening design of the enclosure provides an interference-free vertical passage for the cage system, ensuring both the core operation function of the elevator and effective protection through the surrounding enclosure structure. The adjustable trigger position of the swing door assembly further optimizes the human-machine operation process, significantly reducing the complexity and time cost of equipment installation and adjustment while ensuring operational safety, combining adaptability, safety, and ease of operation.
[0030] In some embodiments, the cage system includes a cage assembly 5 and a detachable climbing platform 7 connected to the outside of the cage assembly 5. The accommodating space formed by the extended guardrail 63, fixed guardrail 64, and swing door guardrail 61 is larger than the space occupied by the cage assembly 5 and the climbing platform 7 after connection. The climbing platform 7 is detachably connected to the outside of the cage assembly 5 to form a temporary working platform. The accommodating space enclosed by the fixed guardrail 64, extended guardrail 63, and swing door guardrail 61 has calculated internal dimensions that maintain a uniform safety clearance around the cage assembly 5 after it is equipped with the climbing platform 7. This ensures that the cage system can remain completely within the protection range of the base frame guardrail 6 when carrying external components. The extra accommodating space effectively avoids rigid collisions between the cage system and the base frame guardrail 6 during lifting and lowering, protecting the equipment structure and eliminating potential jamming risks. The detachable nature of the climbing platform 7 allows the construction party to flexibly configure the working platform according to actual working conditions, ensuring the expandability of high-altitude operations and improving equipment adaptability and operational safety in complex construction scenarios.
[0031] When the climbing platform 7 is removed from the cage device 5, the two extended guardrail plates 63 on the base frame fence 6 can be removed. At this time, the space formed by the fixed guardrail plate 64 and the swing door guardrail plate 61 can accommodate the cage device 5, and the surrounding area can still maintain a uniform safety gap, so that the cage device 5 can be completely placed within the protection range of the base frame fence 6.
[0032] In some embodiments, the cage system also includes a cage stop mounted on the cage assembly 5. The cage stop engages with the swing door drive 66 of the swing door assembly to unlock the swing door 65 by driving the swing door locking member 62 of the swing door assembly. The cage stop is typically a wedge-shaped metal component, mounted on the side of the cage assembly 5 and corresponding to the position of the swing door drive 66. Without the tower climbing platform 7 installed, when the cage assembly 5 is raised or lowered to the height of the swing door drive 66, the cage stop applies mechanical force to the swing door drive 66, causing the swing door drive 66 to rotate and disengage the swing door locking member 62 from the locked position, thereby automatically unlocking the swing door 65. The automatic unlocking triggered by the position of the cage device 5 eliminates the manual operation step, avoiding the risk of personnel forgetting to lock the door, and achieving precise synchronization between the arrival of the cage device 5 and the release of the access control. The mechanical triggering is highly reliable and adaptable to the complex environment of the construction site. At the same time, it ensures that the swing door 65 will only unlock when the cage device 5 is accurately stopped, effectively preventing the possibility of personnel accidentally entering the dangerous area during high-altitude operations.
[0033] In some embodiments, the cage system also includes a climbing platform stop 75 mounted on the climbing platform 7. The climbing platform stop 75 is used to engage with the swing door drive 66 of the swing door assembly to unlock the swing door 65 by driving the swing door locking member 62 of the swing door assembly. The climbing platform stop 75 may have a similar or identical structure to the cage stop, but its installation position is located on the outer frame of the climbing platform 7, corresponding to the position of the swing door drive 66. When the climbing platform 7 is installed, when the cage device 5 carries the climbing platform 7 up and down to the swing door 65 area, the climbing platform stop 75 will mechanically contact and drive the swing door drive 66 to rotate, thereby causing the swing door locking member 62 to disengage from the locked state, realizing the automatic unlocking of the swing door 65. The contact point 75 of the climbing platform ensures that the system can reliably trigger the swing door 65 mechanism even when the cage device 5 is carrying an external work platform, avoiding access control failure due to changes in equipment configuration; the mechanical linkage triggering method can still work stably in harsh construction environments, ensuring that the cage device 5 can achieve accurate automatic access control in different working modes (whether or not it is equipped with the climbing platform 7), and eliminating the risk of possible failures in the electrical system through the mechanical structure.
[0034] In some embodiments, the ground access opening is aligned with the opening of the hoist cage 5; and / or, the ground access opening is aligned with the railing access opening of the tower climbing platform 7. The ground access opening serves as the entry and exit passage for the base frame railing 6, and can completely overlap with the entrance / exit on the side of the hoist cage 5, forming a direct path from the ground to the interior of the hoist cage; it can also be aligned with the access opening on the side railing of the tower climbing platform 7, forming a connecting passage from the ground to the aerial work platform; ensuring that regardless of whether the hoist cage 5 is equipped with the tower climbing platform 7, the ground access opening can always form a continuous passage interface with the currently available entrance. When the hoist cage 5 is parked, the direct alignment of the ground access opening with the opening of the hoist cage 5 allows personnel and materials to enter and exit in a straight line, eliminating the risk of tripping or falling due to lateral movement; and when the tower climbing platform 7 is in use, the precise alignment ensures the continuity of the movement line from the ground to the aerial work platform, significantly improving passage efficiency.
