Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction equipment, specifically relating to a working platform and support equipment. Background Technology

[0002] High slopes in water conservancy and hydropower projects (such as reservoir dam slopes and inlet / outlet slopes of water diversion tunnels) are generally characterized by their great height, steep slope, and complex geological conditions (such as the presence of rock layers with developed fissures and loose deposits). Under natural conditions or engineering disturbances (such as excavation and dewatering), high slopes are prone to instability due to insufficient resistance to sliding, which may cause geological disasters such as landslides and collapses, directly threatening engineering construction and personnel safety.

[0003] Anchor bolt support construction involves embedding anchor bolts deep into stable rock layers within the slope. Utilizing the tensile and shear strength of the anchor bolts, loose or easily sliding rock on the slope surface is anchored to the deep, stable rock mass, forming a stable structure where the anchor bolt and rock mass share the load. Existing integrated drilling, grouting, and anchoring devices can simplify the multiple steps of traditional anchor bolt construction into a single continuous process, achieving fully mechanized operation. Furthermore, this device can precisely control drilling depth, anchor bolt installation angle, and prestressing parameters, ensuring consistent quality in anchor bolt construction. However, in semi-automated operation, operators need to stand close to the integrated drilling, grouting, and anchoring device on high slopes. Additionally, if the integrated drilling, grouting, and anchoring device malfunctions during automated operation and cannot be moved from its operating position, maintenance personnel are required to troubleshoot the problem.

[0004] To address these needs, traditional high slope drilling and anchoring equipment typically involves designing a large boom separately for the working platform. However, this type of boom suffers from problems such as large size and heavy weight. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a working platform and support equipment that can share a large arm with the drilling, injection and anchoring integrated device.

[0008] Preferably, the primary swing arm assembly includes: a first swing arm beam, which is connected to a rotation point on the secondary swing arm assembly; a first rotating assembly, which is connected to the other end of the first swing arm beam and rotates about a vertical direction; and a fixed plate, which is disposed above the first rotating assembly and connected to the first rotating assembly, and the fixed plate is connected to the main arm.

[0009] Preferably, the secondary swing arm assembly has a third state, wherein the secondary swing arm assembly and the primary swing arm assembly are in a folded state; the secondary swing arm assembly has a fourth state, wherein the secondary swing arm assembly and the primary swing arm assembly are in an operating angle state; and the secondary swing arm assembly has a second transition state, wherein the second transition state is when the secondary swing arm assembly switches from the third state to the fourth state.

[0010] Preferably, the secondary swing arm assembly includes: a second swing arm beam, which is connected to one end of the flying arm assembly; and a second rotating assembly, which is connected to the first swing arm beam and rotates about the vertical direction.

[0011] Preferably, the flying arm assembly has a fifth state, which is a state in which the flying arm assembly is close to the secondary swing arm assembly; the flying arm assembly has a sixth state, which is a state in which the flying arm assembly is far away from the secondary swing arm assembly.

[0012] Preferably, the boom assembly includes: a fixed base, one end of which is connected to the swing arm beam; an upper arm, the other end of which is connected to the fixed base; a swing cylinder, one end of which is connected to the other end of the upper arm and connected to the work basket assembly for controlling the work basket assembly to swing horizontally; and a lower arm, which is connected to the swing cylinder and the fixed base respectively; the fixed base, the upper arm, the swing cylinder, and the lower arm form a parallelogram structure.

[0013] Preferably, the boom assembly includes: a telescopic cylinder, the telescopic cylinder being placed inside the parallelogram structure, the fixed end of the telescopic cylinder being connected to the fixed base, and the telescopic end of the telescopic cylinder being connected to the side of the swing cylinder, the telescopic cylinder being used to control the movement of the work basket assembly in the vertical direction.

[0014] A support device includes a boom, a working platform as described above, and a leveling assembly connected to the boom for providing support to the working platform and for adjusting the working basket assembly to remain parallel to the ground.

[0015] This utility model provides a working platform, including a working basket assembly, a primary swing arm assembly connected to the boom of a drilling and anchoring integrated device, used to adjust the posture of the primary swing arm assembly and the boom; a secondary swing arm assembly connected to the primary swing arm assembly, used to adjust the angle between the secondary and primary swing arm assemblies; and a flying arm assembly connected to both the secondary swing arm assembly and the working basket assembly, used to adjust the position between the working basket assembly and the secondary swing arm assembly. This utility model also provides a support device, including a boom, the aforementioned working platform, and a leveling assembly connected to the boom, used to provide support for the working platform and to adjust the working basket assembly to maintain parallelism with the ground.

[0016] The primary swing arm assembly of the work platform provided by this utility model is directly connected to the boom of the integrated drilling, grouting, and anchoring device, eliminating the need for a separate independent support structure for the work platform. Essentially, it achieves shared boom between the work platform and the integrated drilling, grouting, and anchoring device through mechanical connection. This design avoids the problems of large size and heavy weight caused by the separate boom of traditional platforms, realizing functional synergy between drilling, grouting, and anchoring operations and personnel operation / maintenance, and improving the overall utilization rate of the integrated drilling, grouting, and anchoring device. Furthermore, the primary swing arm assembly of the work platform provided in this application is used for basic posture adjustment, the secondary swing arm assembly is used for angle expansion, and the boom assembly is used for precise position fine-tuning. This creates a hierarchical mechanical structure of coarse adjustment—medium adjustment—fine adjustment, solving the problems of either small coverage area or low positioning accuracy of traditional platforms. Through simple mechanical connections and action logic, it achieves a balance between a large working space and high-precision end-point positioning. Without complex multi-system coordination, simple mechanical action linkage can meet the needs of high slope construction, requiring both reaching distant points and precise alignment with the work point, thus achieving a high degree of unity between the functionality and practicality of the mechanical structure. On the other hand, the core functions of each component of the working platform provided by this utility model are achieved through single or simple mechanical actions: posture adjustment of the first-stage swing arm component, angle adjustment of the second-stage swing arm component, and position adjustment of the flying arm component. There are no redundant mechanical structures or complex transmission systems. This simplified design reduces the mechanical complexity of the working platform, decreases the number of parts and assembly difficulty, and lowers manufacturing costs. Furthermore, the simple mechanical actions reduce potential failure points (such as avoiding jamming or damage caused by multiple transmission links), improving the reliability of the working platform in harsh construction environments on high slopes. It also facilitates later maintenance, requiring only inspection of the mechanical actions of individual components without disassembling complex linkage systems. The support equipment provided by this utility model, including the working platform, also possesses the above-mentioned beneficial effects. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0020] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Figures 1 to 3 As shown, this utility model provides a working platform 11, which includes a working basket assembly 114 and a primary swing arm assembly 111, which is connected to the boom 13 of the drilling and anchoring integrated device and is used to adjust the posture of the primary swing arm assembly 111 and the boom 13; a secondary swing arm assembly 112, which is connected to the primary swing arm assembly 111 and is used to adjust the angle between the secondary swing arm assembly 112 and the primary swing arm assembly 111; and a flying arm assembly 113, which is connected to the secondary swing arm assembly 112 and the working basket assembly 114 respectively and is used to adjust the position between the working basket assembly 114 and the secondary swing arm assembly 112.

[0022] The primary swing arm assembly 111 is the direct connection carrier between the working platform 11 and the boom 13 of the drilling and anchoring integrated device. Its core function is to adjust its posture relative to the boom 13 through its own structural movements, providing a stable reference for the movement of subsequent components. From a mechanical logic perspective, the primary swing arm assembly 111 first forms a rigid connection with the boom 13 (ensuring stable load transmission), and then changes its relative posture with the boom 13. For example, it can rotate around the connection point with the boom 13, adjusting its original close-to-the-boom-13 retracted posture to an outward-extending working posture to counteract the slight tilt of the boom 13 caused by the high slope construction scenario, ensuring that it is always in a horizontal or preset working posture, providing a stable installation and movement foundation for the secondary swing arm assembly 112.

[0023] The direct connection between the secondary swing arm assembly 112 and the primary swing arm assembly 111 focuses on adjusting the angle between themselves and the primary swing arm assembly 111. Essentially, it extends the platform's working range through angle changes. From a mechanical motion perspective, the secondary swing arm assembly 112 can rotate around the connection point of the primary swing arm assembly 111, changing the included angle between them. When the included angle is small, the secondary swing arm assembly 112 and the primary swing arm assembly 111 are in a folded state, reducing the overall volume of the platform. When the included angle increases to a preset angle, the secondary swing arm assembly 112 unfolds along the extension direction of the primary swing arm assembly 111, significantly increasing the platform's horizontal coverage distance. This angle adjustment does not require an additional power source; it only relies on the mechanical connection with the primary swing arm assembly 111. Through a simple rotational motion, the potential coverage of the work basket assembly 114 can be expanded to the sum of the lengths of the primary swing arm assembly 111 and the secondary swing arm assembly 112, meeting the operational needs of different locations on high slopes.

[0024] The flying arm assembly 113 connects the secondary swing arm assembly 112 and the working basket assembly 114, and is the core mechanical mechanism for achieving precise position adjustment of the working basket assembly 114. Its function is to finely correct the position of the working basket assembly 114 after the primary swing arm assembly 111 and the secondary swing arm assembly 112 have determined the approximate working range. From a mechanical perspective, the flying arm assembly 113 can change the relative position of the working basket assembly 114 and the secondary swing arm assembly 112 by itself. For example, the flying arm assembly 113 can push the working basket assembly 114 further away through its extension and retraction motion. The position can be finely adjusted horizontally by moving away from or closer to the secondary swing arm assembly 112, or the height of the working basket assembly 114 can be adjusted by swinging motion to meet the operational needs of different elevations on high slopes. This position adjustment has the characteristics of small range and high precision, which can make up for the shortcomings of the large range and coarse adjustment of the primary swing arm assembly 111 and the secondary swing arm assembly 112, ensuring that the working basket assembly 114 can accurately reach the operation point or maintenance point required by the operator, while avoiding the problem of decreased platform stability caused by large movements of the primary swing arm assembly 111 and the secondary swing arm assembly 112.

[0025] The work basket assembly 114 is the final load-bearing component of the work platform 11. It does not directly participate in the active adjustment of its posture, angle, or position. Instead, through mechanical connection with the boom assembly 113, and relying on the posture / angle adjustments of the primary swing arm assembly 111 and the secondary swing arm assembly 112, as well as the position adjustment of the boom assembly 113, it achieves precise movement within the work space. From a mechanical function perspective, the core of the work basket assembly 114 is rigid load-bearing and safety protection. Its structural design must match the motion characteristics of other components. It needs sufficient strength to withstand the weight load of personnel and tools, while also adapting to the position adjustment movements of the boom assembly 113 to ensure stability during movement (e.g., avoiding swaying or tilting). Ultimately, it provides a safe and fixed working space for operators or maintenance personnel, transforming the mechanical adjustment effects of other components into actual operational capabilities.

[0026] Therefore, it can be seen that the first-stage swing arm assembly 111 of the working platform 11 provided by this utility model is directly connected to the main arm 13 of the drilling, injection and anchoring integrated device. There is no need to design an independent support structure for the working platform 11. In essence, the working platform 11 and the drilling, injection and anchoring integrated device share the main arm 13 through mechanical connection. This design avoids the problems of large size and heavy weight caused by the separate main arm 13 of the traditional platform. It realizes the functional synergy between drilling, injection and anchoring operations and personnel operation / maintenance, and improves the comprehensive utilization rate of the drilling, injection and anchoring integrated device.

[0027] In addition, the first-level swing arm assembly 111 of the work platform 11 provided in this application is used for basic posture adjustment, the second-level swing arm assembly 112 is used for angle expansion range, and the flying arm assembly 113 is used for precise position fine adjustment. In this way, the work platform 11 forms a hierarchical mechanical structure of coarse adjustment - medium adjustment - fine adjustment, which not only solves the problem of traditional platforms having either a small coverage area or low positioning accuracy, but also achieves a balance between a large working space and high-precision end positioning through simple mechanical connection and action logic. Without the need for complex multi-system coordination, it can meet the needs of high slope construction to reach distant points and accurately align with the work point through simple mechanical action linkage, so that the functionality and practicality of the mechanical structure are highly unified. On the other hand, the core functions of each component of the work platform 11 provided by this utility model are achieved through single or simple mechanical actions. The first-level swing arm component 111 adjusts its posture, the second-level swing arm component 112 adjusts its angle, and the flying arm component 113 adjusts its position. There are no redundant mechanical structures or complex transmission systems. This simplified design reduces the mechanical complexity of the work platform 11, reduces the number of parts and assembly difficulty, and lowers manufacturing costs. On the other hand, simple mechanical actions can reduce failure points (such as avoiding jamming or damage caused by multiple transmission links), improve the reliability of the work platform 11 in the harsh construction environment of high slopes, and facilitate later maintenance. Only the mechanical actions of a single component need to be inspected, without disassembling the complex linkage system.

[0028] Among them, the first-stage swing arm assembly 111 has a first state, in which the first-stage swing arm assembly 111 is in close contact with the upper arm 13; The first-stage swing arm assembly 111 has a second state, in which the first-stage swing arm assembly 111 and the upper arm 13 are at a preset angle. The primary swing arm assembly 111 has a first transition state, in which the primary swing arm assembly 111 switches from being close to the upper arm 13 to the primary swing arm assembly 111 and the upper arm 13 forming a preset angle.

[0029] The primary swing arm assembly 111 serves as the core connection between the working platform 11 and the boom 13 of the integrated drilling, grouting, and anchoring device. Its functionality depends on the orderly switching between the first state, the first transition state, and the second state. The definition, characteristics, and switching logic of each state directly determine the storage convenience and operational range expansion capability of the working platform 11. A detailed analysis follows: First state: The stowed state, close to the boom 13. The first state is the non-operation stowed state of the primary swing arm assembly 111. The core feature is that the primary swing arm assembly 111 is close to the boom 13. In this state, the relative position of the primary swing arm assembly 111 and the boom 13 is highly fitted, with no obvious gaps or angles. Its design purpose is to minimize the overall volume of the working platform 11. When the drilling, grouting and anchoring integrated device is in a non-operational movement phase, such as traveling along a high slope construction access road, or when the working platform 11 is not in use, the primary swing arm assembly 111, by being close to the boom 13, avoids increasing the overall width and height of the equipment due to its own protrusion, reducing the space occupied on the construction site, and reducing the risk of collision with the slope rock mass and other equipment during movement, ensuring the safety and flexibility of equipment movement.

[0030] The second state: the operational readiness state at a preset angle to the boom 13. This second state is the basic operational state of the first-stage swing arm assembly 111. Its core feature is that the first-stage swing arm assembly 111 is at a preset angle to the boom 13. This preset angle needs to be set in conjunction with the high slope construction requirements. Its core function is to reserve sufficient space for the subsequent deployment of the second-stage swing arm assembly 112 and the movement of the boom assembly 113, and to initially determine the operational direction and range of the work platform 11. In this state, the first-stage swing arm assembly 111 is no longer tightly attached to the boom 13, but rather extends outward at a preset angle, forming the first layer of support structure for the work platform 11. This structure can bear the weight load of the second-stage swing arm assembly 112, the boom assembly 113, and the work basket assembly 114, and through its fixed angle and posture, it provides a stable benchmark for the precise adjustment of each component, ensuring that the work platform 11 as a whole is in an initial posture that meets the operational requirements.

[0031] The first transitional state is the intermediate state between storage and operation. It is a dynamic switching phase connecting the first and second states. Its core characteristic is that the primary swing arm assembly 111 gradually switches from a state of close contact with the main boom 13 to a state where the main boom 13 is at a preset angle. This state is not a fixed posture but a continuous dynamic process. Before the switching begins, the primary swing arm assembly 111 is in the first state (close to the main boom 13). During the switching process, the primary swing arm assembly 111 gradually rotates around the connection point of the main boom 13, and the angle between it and the main boom 13 gradually increases. After the switching is completed, the angle reaches the preset value, and the primary swing arm assembly 111 stabilizes in the second state. The core function of the first transitional state is to achieve a shock-free and smooth switching, avoiding excessive force on the components or platform shaking due to sudden changes in posture. Simultaneously, through a controllable switching speed, it ensures that operators can adjust the switching progress in real time according to the construction environment (such as the location of slope obstacles), ensuring the safety of the switching process.

[0032] The state switching of the primary swing arm assembly 111 needs to be triggered in conjunction with the operational requirements of the drilling, injection, and anchoring integrated device. When the equipment needs to be moved or the work platform 11 is idle, the switching from "second state - first transition state - first state" is triggered, and the primary swing arm assembly 111 is tightly attached to the boom 13 for storage. When the equipment arrives at the work position and the work platform 11 needs to be unfolded for operation or maintenance, the switching from "first state - first transition state - second state" is triggered, and the primary swing arm assembly 111 is unfolded to a preset angle to lay the foundation for subsequent operations. This logic of switching on demand allows the primary swing arm assembly 111 to flexibly adapt to different scenarios such as movement, operation, and idleness, avoiding functional idleness caused by a fixed state. Another important aspect is that the first transition state, as an intermediate link in the switching process, has the key value of buffering and regulation. Compared to the direct jump from the first state to the second state, the dynamic transition process can reduce the impact on the connection point of the boom 13 by controlling the rotation speed and force of the first-stage swing arm assembly 111, thus extending the service life of the mechanical structure. At the same time, the operator can observe the distance between the first-stage swing arm assembly 111 and the surrounding environment (such as slope rock mass, other equipment) during the transition process. If a collision risk is found, the switching can be temporarily paused, adjusted, and then continued, improving operational safety. The clear division between the first state and the second state respectively ensures the convenience of storage when moving the equipment and the structural stability during operation. The combination of the two allows the first-stage swing arm assembly 111 to meet the needs of construction efficiency while also taking into account safety and durability.

[0033] In the embodiments provided by this utility model, the first-stage swing arm assembly 111 includes: a first swing arm beam 1113, which is connected to a rotation point on the second-stage swing arm assembly 112; a first rotating assembly 1112, which is connected to the other end of the first swing arm beam 1113 and rotates about the vertical direction; and a fixing plate 1111, which is disposed above the first rotating assembly 1112 and connected to the first rotating assembly 1112, and is connected to the upper arm 13.

[0034] The primary swing arm assembly 111, through the rigid connection and functional coordination of the swing arm beam 1113, the rotating assembly 1112, and the fixed plate 1111, fulfills its core function of connecting the main arm 13 with the secondary swing assembly to adjust its posture by rotating around the vertical direction. The structural relationship and functional positioning of its components are as follows: The fixing plate 1111 is a core component connecting the primary swing assembly and the boom 13 of the drilling and anchoring integrated device. Its installation position is clearly defined above the rotating assembly 1112 and directly connected to it. On one hand, the fixing plate 1111 needs to be rigidly fixed to the boom 13 to ensure that the weight load of the entire primary swing arm assembly 111, as well as the subsequent secondary swing arm assembly 112, flying arm assembly 113, and work basket assembly 114, can be stably transmitted to the boom 13, preventing platform swaying or detachment due to loose connections. On the other hand, the fixing plate 1111 provides an installation reference for the rotating assembly 1112. Through precise connection with the rotating assembly 1112, it limits the rotation center and range of the rotating assembly 1112, ensuring that subsequent rotational movements can be stably performed around a preset vertical axis, laying a structural foundation for attitude adjustment.

[0035] Rotating component 1112 is the power actuator that enables vertical rotation. When it is necessary to switch the state of the primary swing arm assembly 111 (e.g., from a retracted state close to the boom 13 to an operating state where the boom 13 is at a preset angle), rotating component 1112 can rotate around the vertical direction, thereby driving the connected swing arm beam 1113 to rotate synchronously around the vertical axis, changing the relative angle between the swing beam and the boom 13. Structurally, the rotation center of rotating component 1112 is defined by the connection position of the fixed plate 1111 and the swing beam, ensuring that there is no offset during rotation. At the same time, the design of rotating around the vertical direction can directly realize the attitude adjustment of the primary swing arm assembly 111 in the horizontal plane, such as left and right rotation, without the need for additional height adjustment, adapting to the need for horizontal expansion of the working range in high slope construction.

[0036] The swing arm beam 1113 serves as the force transmission carrier connecting the rotating assembly 1112 and the secondary swing arm assembly 112. Both ends of the swing arm beam 1113 perform different connection functions: one end connects to the rotating assembly 1112, and the other end connects to the rotation point on the secondary swing arm assembly 112, forming a force transmission path between the rotating assembly 1112, the swing arm beam 1113, and the secondary swing arm assembly 112. Functionally, the swing arm beam 1113 has a dual role: firstly, it bears the load, needing to support the weight of the secondary swing arm assembly 112 and all subsequent components, and secondly, it transmits the load through… The rotating component 1112 and the fixed plate 1111 transmit the load to the boom 13. Therefore, its structure must have sufficient rigidity and strength to avoid bending or breakage due to excessive load. Secondly, the motion is transmitted. When the rotating component 1112 rotates around the vertical direction, the swing arm beam 1113 will rotate synchronously with the rotating component 1112 and transmit this rotational motion to the secondary swing arm component 112 connected to it. This causes the secondary swing arm component 112 to adjust its position synchronously, providing the prerequisite for the secondary swing arm component 112 to adjust its angle with the primary swing arm component 111 and expand the working range.

[0037] Therefore, the three main components of the primary swing arm assembly 111 form a complete functional loop through the logical coordination of "fixed plate 1111 setting the reference, rotating component 1112 providing power, and swing arm beam 1113 transmitting motion and load." First, the fixed plate 1111 is fixed to the boom 13, providing stable support for the entire assembly. Second, the rotating component 1112 rotates in the vertical direction, generating power for attitude adjustment. Finally, the swing arm beam 1113 transmits the rotation of the rotating component 1112 to the secondary swing arm assembly 112, while also bearing the load of subsequent components and transmitting it to the boom 13. This structural design ensures that the primary swing arm assembly 111 can stably connect the boom 13 and the secondary swing arm assembly 112, and also enables flexible attitude adjustment through the vertical rotation of the rotating component 1112. This provides structural support for the primary swing arm assembly 111 to switch between a retracted state close to the boom 13 and an operating state at a preset angle, while simultaneously meeting the dual functional requirements of load transmission and attitude adjustment.

[0038] In the embodiments provided by this utility model, the secondary swing arm assembly 112 has a third state, in which the secondary swing arm assembly 112 and the primary swing arm assembly 111 are in a folded state; the secondary swing arm assembly 112 has a fourth state, in which the secondary swing arm assembly 112 and the primary swing arm assembly 111 are in an operating angle state; the secondary swing arm assembly 112 has a second transition state, in which the secondary swing arm assembly 112 switches from the third state to the fourth state.

[0039] The third state is the non-operational storage form of the secondary swing arm assembly 112. Its core feature is that it is folded together with the primary swing arm assembly 111, meaning the secondary swing arm assembly 112 fits snugly against the primary swing arm assembly 111 at a very small angle. Functionally, the core value of this state lies in reducing the overall volume of the working platform 11. When the drilling, grouting, and anchoring integrated device is in motion, such as traveling along a high slope construction road, or when the working platform 11 is not in use, the secondary swing arm assembly 112, by folding together with the primary swing arm assembly 111, avoids protruding and increasing the equipment's lateral dimensions, reducing its occupation of narrow construction spaces. It also reduces the risk of collisions with the slope rock mass and surrounding equipment during movement, ensuring the flexibility and safety of equipment movement. Furthermore, the folded state reduces wear and tear on the secondary swing arm assembly 112 from long-term exposure to high slope dust and rainwater, extending the assembly's service life.

[0040] The fourth state is the operational readiness state of the secondary swing arm assembly 112. Its core feature is that it is at an operational angle with the primary swing arm assembly 111. The core value of this state is to expand the operational range of the work platform 11. When the work platform 11 needs to be put into use (such as when operators operate the drilling, injection, and anchoring integrated device at close range, or when maintenance personnel handle equipment failures), the secondary swing arm assembly 112 forms a preset operational angle with the primary swing arm assembly 111 and extends along the extension direction of the primary swing arm assembly 111. This expands the potential coverage area of ​​the work basket assembly 114 from the length of the primary swing arm assembly 111 to the length of the primary swing arm assembly 111 plus the length of the secondary swing arm assembly 112, covering more distant and complex work points on high slopes. At the same time, the fixed operational angle provides a stable benchmark for the subsequent adjustment of the position of the work basket assembly 114 by the flying arm assembly 113, ensuring that the fine-tuning action of the flying arm assembly 113 is precise and controllable, and avoiding the shaking of the work basket assembly 114 due to the unstable posture of the secondary swing arm assembly 112.

[0041] The second transition state is the switch from the third state to the fourth state. This second transition state is not a fixed static state, but rather a dynamic switching process connecting the third and fourth states. Its core feature is the gradual transformation of the secondary swing arm assembly 112 from the folded state of the primary swing arm assembly 111 to the working angle state. From a functional logic perspective, the core value of this state lies in achieving a shock-free and controllable state switch. Before the switch begins, the secondary swing arm assembly 112 is stably in the third state. During the switch, the secondary swing arm assembly 112 slowly rotates around the connection point of the primary swing arm assembly 111, and the angle between it and the primary swing arm assembly 111 gradually increases from a minimum value to a preset working angle. This process can prevent sudden changes in component force by controlling the rotation speed, preventing imbalance of the primary swing arm assembly 111 or overall shaking of the work platform due to sudden changes in posture. Simultaneously, the operator can observe the distance between the secondary swing arm assembly and the surrounding environment (such as protruding parts of the slope, components of the drilling and anchoring integrated device) in real time during the transition state. If an interference risk is detected, the switch can be paused in time, the angle adjusted, and then continued, ensuring the safety and reliability of the switch process.

[0042] Therefore, the three states of the secondary swing arm assembly 112 do not exist independently, but form a complete closed loop through the logic of demand triggering—state switching—function implementation. When the drilling-anchoring integrated device needs to be moved or the working platform 11 is idle, the secondary swing arm assembly 112 is in the third state (folded), meeting the space adaptation requirements. When the equipment arrives at the work position and the working platform 11 needs to be unfolded, the second transition state is triggered, and the switch from folded to working angle is achieved through smooth rotation, solving the problem of sudden state change risk. After the switch is completed, the secondary swing arm assembly 112 is stably in the fourth state (working angle), providing support for the subsequent adjustment of the working basket assembly 114 by the boom assembly 113, allowing the operator to carry out the work and meeting the needs of expanding the working range. This state switching logic takes into account both the convenience of storage when not in operation and the range and accuracy during operation. At the same time, the second transition state buffer balances the contradiction between rapid switching and safety and stability, enabling the secondary swing arm assembly 112 to flexibly adapt to the scene switching from moving to the working position during high-side construction.

[0043] In the embodiments provided by this utility model, the secondary swing arm assembly 112 includes: a second swing arm beam 1122, which is connected to one end of the flying arm assembly 113; and a second rotating assembly 1121, which is connected to the first swing arm beam 1113 and rotates around the vertical direction.

[0044] The second swing arm beam 1122 is the main structural component of the second-stage swing arm assembly 112. Its core connection function is directed towards the flying arm assembly 113. One end of the second swing arm beam 1122 is directly connected to one end of the flying arm assembly 113, forming a mechanical transmission path from the second-stage swing arm assembly 112 to the flying arm assembly 113. From a functional perspective, the second swing arm beam 1122 not only bears the weight load of the flying arm assembly 113 and the subsequent working basket assembly 114, but also stably transmits the force of the subsequent assembly to the first-stage swing arm assembly 111. At the same time, as a motion carrier driven by the second rotating component 1121, it transmits the rotational motion to the flying arm assembly 113, providing basic support for the flying arm assembly 113 to adjust the position of the working basket assembly 114.

[0045] Rotating component 2 1121 is connected to the first-stage swing arm assembly 111's swing arm beam 1113 and has the characteristic of rotating around the vertical direction. This characteristic is the core power source for the second-stage swing arm assembly 112 to achieve state switching. When it is necessary to switch the second-stage swing arm assembly 112 from the folded state (third state) of the first-stage swing arm assembly 111 to the working angle state (fourth state), rotating component 2 1121 rotates around the vertical direction. Through its connection with the first-stage swing arm beam 1113, it drives the second-stage swing arm beam 1122 to rotate synchronously around the vertical axis, thereby changing the relative angle between the second-stage swing arm beam 1122 and the first-stage swing arm beam 1113, and finally realizing the attitude adjustment of the second-stage swing arm assembly 112, laying the foundation for expanding the working range.

[0046] Therefore, it can be seen that the two core structures of the secondary swing arm assembly 112 form a complete functional closed loop through the collaborative logic of "rotating component 2 1121 providing power and swing arm beam 2 1122 transmitting motion and load". First, the rotating component 2 1121 is connected to the swing arm beam 1 1113, and uses vertical rotation as power to drive the secondary swing arm assembly 112 to adjust its overall posture, meeting the requirements of switching between folding and operation. Second, the swing arm beam 2 1122 receives the rotational power of the rotating component 2 1121, which drives the flying arm assembly 113 to adjust its position synchronously. At the same time, it bears the load of the flying arm assembly 113 and subsequent components, and transmits it to the primary swing arm assembly 111 through the rotating component 2 1121, ensuring the overall structural stability. This structural design not only achieves an effective connection between the secondary swing arm assembly 112 and the primary swing arm assembly 111 and the flying arm assembly 113, but also gives the secondary swing arm assembly 112 a flexible attitude adjustment capability through the vertical rotation characteristics of the rotating assembly 1121, perfectly adapting to the dual needs of storage and capacity reduction and operation expansion in high slope construction.

[0047] Furthermore, the flying arm assembly 113 has a fifth state, which is the state in which the flying arm assembly 113 is close to the secondary swing arm assembly 112; the flying arm assembly 113 also has a sixth state, which is the state in which the flying arm assembly 113 is far away from the secondary swing arm assembly 112.

[0048] The fifth state is the non-operational storage state of the boom assembly 113. Its core feature is that the boom assembly 113 is close to the secondary swing arm assembly 112, meaning that the gap between the boom assembly 113 and the secondary swing arm assembly 112 is extremely small, and the structure fits tightly. From a functional perspective, the core value of this state lies in its ability to reduce the overall platform size. When the working platform 11 is in a storage state (such as when the drilling, injection, and anchoring integrated device is moved or idle), the boom assembly 113 avoids protruding and increasing the horizontal or vertical dimensions of the platform by being close to the secondary swing arm assembly 112, further reducing the overall volume of the working platform 11, reducing the space occupied on the construction site, and reducing the risk of collision between the boom assembly 113 and the slope rock mass or other equipment during movement. This ensures the flexibility and safety of equipment movement and also reduces environmental wear and tear on the boom assembly 113 when not in operation.

[0049] The sixth state is the operational function state of the boom assembly 113. Its core characteristic is that the boom assembly 113 is moved away from the secondary swing arm assembly 112, meaning a certain distance is formed between them, disengaging from their contact state. The core value of this state lies in expanding the positional space for the work basket assembly 114. When the work platform 11 needs to be put into use (e.g., when operators operate the drilling and anchoring device, or maintenance personnel handle malfunctions), the boom assembly 113, moving away from the secondary swing arm assembly 112, can drive the connected work basket assembly 114 to move away from the secondary swing arm assembly 112. This avoids interference between the work basket assembly 114 and the secondary swing arm assembly 112 and the primary swing arm assembly 111. Furthermore, it pushes the work basket assembly 114 closer to the high slope work point, filling the positional gap left by the deployment of the primary swing arm assembly 111 and the secondary swing arm assembly 112. This provides the prerequisite for the work basket assembly 114 to accurately align with the operation or maintenance point, ensuring that operators can carry out operations safely and conveniently.

[0050] Therefore, the fifth and sixth states of the boom assembly 113 are not independent, but rather complement each other based on the needs of storage and operation. In non-operational situations, the fifth state minimizes size by being "close," adapting to both equipment movement and idle periods. In operation, the sixth state expands the operating space by being further away, adapting to actual operation and maintenance needs. This state division ensures both the spatial adaptability of the boom assembly 113 in non-operational phases and its functional practicality in operation phases. This is the foundation for the boom assembly 113 to fulfill its core function of connecting the secondary swing arm assembly 112 and the operating basket assembly 114, and adjusting the position of the operating basket assembly 114.

[0051] In the embodiments provided by this utility model, the flying arm assembly 113 includes: a fixed base 1131, one end of which is connected to the swing arm beam 1122; an upper arm 1132, the other end of which is connected to the fixed base 1131; a swing cylinder 1133, one end of which is connected to the other end of the upper arm 1132, and the swing cylinder 1133 is connected to the work basket assembly 114 for controlling the work basket assembly 114 to swing in the horizontal direction; and a lower arm 1134, which is connected to the swing cylinder 1133 and the fixed base 1131 respectively; the fixed base 1131, the upper arm 1132, the swing cylinder 1133 and the lower arm 1134 form a parallelogram structure.

[0052] The fixed base 1131 is the basic connecting component of the boom assembly 113. One end of it is directly connected to the second swing arm beam 1122 of the secondary swing arm assembly 112. Its core function is to establish a rigid connection between the boom assembly 113 and the secondary swing arm assembly 112, provide a stable installation reference for the entire boom assembly 113, ensure that the movement of each component can proceed in an orderly manner around the fixed reference, and bear the load of the boom assembly 113 and the work basket assembly 114, and transfer the load to the second swing arm beam 1122.

[0053] The upper arm 1132 and lower arm 1134 form a supporting frame for a parallelogram structure. One end of the upper arm 1132 is connected to the other end of the fixed base 1131, and the other end is connected to the end of the swing cylinder 1133. It forms the upper side of the parallelogram structure, and its main function is to transmit the power of the swing cylinder 1133 and work with the lower arm 1134 to maintain structural stability, driving the working basket assembly 114 to move with the parallelogram structure. The two ends of the lower arm 1134 are connected to the swing cylinder 1133 and the fixed base 1131, respectively. As the lower side of the parallelogram structure, it is symmetrically distributed with the upper arm 1132. It not only assists the upper arm 1132 in supporting the weight of the swing cylinder 1133 and the working basket assembly 114, but also ensures the integrity of the parallelogram structure and avoids structural deformation during movement through its connection with the fixed base 1131 and the swing cylinder 1133.

[0054] The swing cylinder 1133 is the power source and connecting link for the horizontal swing of the working basket assembly 114. One end of the swing cylinder 1133 is connected to the upper arm 1132, and the other end is connected to the working basket assembly 114. It has a dual function: first, power output, which drives the upper arm 1132 to rotate around the fixed base 1131 through its own extension and retraction, thereby driving the overall movement of the parallelogram structure and ultimately controlling the horizontal swing of the working basket assembly 114; second, connection function, which serves as the direct connection between the flying arm assembly 113 and the working basket assembly 114, transmitting the movement of the flying arm assembly 113 to the working basket assembly 114, while also bearing the weight load of the working basket assembly 114.

[0055] Therefore, the fixed base 1131, upper arm 1132, swing cylinder 1133, and lower arm 1134 together form a parallelogram structure. This structural design is the core of the flying arm assembly 113's functionality. When the swing cylinder 1133 extends or retracts, due to the parallelogram's property of "opposite sides being parallel and equal," the upper arm 1132 and lower arm 1134 will rotate synchronously around the fixed base 1131, always maintaining a parallel state. This synchronous movement ensures that the working basket assembly 114 will not tilt during horizontal swinging, maintaining a stable posture. Furthermore, the precise extension and retraction of the swing cylinder 1133 allows for controllable adjustment of the horizontal swing of the working basket assembly 114, meeting the need for fine-tuning the horizontal posture of the working basket assembly 114 during high slope construction. Simultaneously, the structural symmetry distributes the load, enhancing the overall load-bearing capacity and movement stability of the flying arm assembly 113.

[0056] In the embodiments provided by this utility model, the flying arm assembly 113 includes: a telescopic cylinder 1135, which is placed inside a parallelogram structure. The fixed end of the telescopic cylinder 1135 is connected to the fixed base 1131, and the telescopic end of the telescopic cylinder 1135 is connected to the side of the swing cylinder 1133. The telescopic cylinder 1135 is used to control the movement of the work basket assembly 114 in the vertical direction.

[0057] The telescopic cylinder 1135 is a key functional component of the flying arm assembly 113. Its installation position is clearly defined inside the parallelogram structure of the flying arm assembly 113, forming an embedded layout. This design does not occupy additional space outside the parallelogram structure and can coordinate with other components. In terms of connection, the two ends of the telescopic cylinder 1135 correspond to different connection objects: one end is the fixed end, which is directly connected to the fixed seat 1131 of the parallelogram structure. The fixed seat 1131 is relatively stable and provides reliable installation support for the telescopic cylinder 1135. The other end is the telescopic end, which is connected to the side of the swing cylinder 1133 in the parallelogram structure. The telescopic end can flexibly extend and retract with the movement of the cylinder, thereby driving the swing cylinder 1133 to move synchronously, establishing a mechanical transmission path from the fixed seat 1131 to the telescopic cylinder 1135 and the swing cylinder 1133.

[0058] Therefore, the core function of the telescopic cylinder 1135 is to control the vertical movement of the work basket assembly 114. Its function is entirely dependent on the connection relationship with the fixed base 1131 and the swing cylinder 1133, as well as the characteristics of the parallelogram structure. When the telescopic end of the telescopic cylinder 1135 extends, it will generate a thrust on the side of the swing cylinder 1133, pushing the swing cylinder 1133 to rotate around the connection point with the upper arm 1132. This will drive the upper arm 1132 and the lower arm 1134 of the parallelogram structure to rotate synchronously around the fixed base 1131 (because the opposite sides of the parallelogram are parallel and equal, the rotation angles of the upper arm 1132 and the lower arm 1134 are the same). This synchronous rotation will drive the work basket assembly 114 connected to the swing cylinder 1133 to move upward. Conversely, when the telescopic cylinder 1135 retracts, it exerts a pulling force on the side of the swing cylinder 1133, causing the swing cylinder 1133 to rotate in the opposite direction. The upper arm 1132 and lower arm 1134 of the parallelogram structure then rotate synchronously in the opposite direction, and the working basket assembly 114 moves downwards. Throughout this process, the telescopic cylinder 1135, through its own telescopic action and utilizing the motion transmission characteristics of the parallelogram structure, converts linear telescopic movement into vertical movement of the working basket assembly 114, achieving precise control of the vertical position of the working basket.

[0059] In the embodiments provided by this utility model, a support device includes a boom 13, a working platform 11 as described above, and a leveling component 131. The leveling component 131 is connected to the boom 13 and is used to provide support for the working platform 11 and to adjust the working basket component 114 to keep it parallel to the ground.

[0060] The core structure of this support equipment includes the boom 13, the aforementioned working platform 11, and the leveling component 131. These three components form a functional whole through a clear connection relationship. The boom 13 is the basic support and load-bearing component of the equipment. The working platform 11 (including the primary swing arm component 111, the secondary swing arm component 112, the flying arm component 113, and the working basket component 114) relies on the boom 13 to realize its working function. The leveling component 131 serves as a key auxiliary component, directly connected to the boom 13, and provides core support for the working platform 11 and the working basket component 114.

[0061] Among them, the leveling component 131 has a dual core function. First, it provides stable support for the work platform 11. After the leveling component 131 is connected to the boom 13, it serves as the support for the installation and load-bearing of the work platform 11. It can stably transfer the weight load of the work platform 11 (including the first-stage swing arm component 111, the second-stage swing arm component 112, the flying arm component 113, and the work basket component 114) to the boom 13, so as to avoid problems such as loose connection and shaking of the work platform 11 during the unfolding, operation or adjustment process, and ensure the stability of the overall structure of the work platform 11, providing a safe working foundation for operators or maintenance personnel. Secondly, another core function of the leveling component 131 is to dynamically adjust the posture of the working basket component 114. During the operation of the support equipment, no matter what angle deviation the boom 13 may have due to the high slope construction environment (such as slope inclination or uneven ground), the leveling component 131 can correct the posture of the working platform 11 in real time through its own adjustment function, ultimately ensuring that the working basket component 114 always remains parallel to the ground, avoiding safety hazards such as operators being unstable or tools slipping due to the tilt of the working basket component 114, while ensuring the accuracy and safety of drilling, injection, anchoring operations or fault maintenance.
