Description

Technical Field

[0001] This invention belongs to the field of hoist installation technology, and specifically relates to an installation system and method for installing trolley-type hoists in tunnels. Background Technology

[0002] In the cavern engineering of water conveyance systems, due to the core needs of controlling construction costs, avoiding excavation risks, and improving geological adaptability, the design of the interior space of the cavern generally presents the characteristics of "small and compact". This layout feature directly poses a key constraint on the installation of large lifting equipment such as hoists and bridge cranes. Due to the mismatch between the size and the working space, conventional large lifting equipment such as truck cranes cannot enter the cavern to carry out installation work.

[0003] Among them, the installation of trolley-type gate hoists is particularly difficult. Due to the large overall size of the trolley-type gate hoist and the limited space of the cavern, it is not possible to directly transport it to the high-altitude installation platform (track beam) by "whole hoisting". The trolley-type gate hoist must be disassembled into multiple independent parts and then hoisted to the high-altitude installation platform in batches for assembly.

[0004] However, new problems arise as well. The working area of ​​an aerial installation platform is limited. (See...) Figure 3 The high-altitude installation platform has holes in the middle, and the only supporting parts are the upstream and downstream crossbeams, which cannot meet the assembly requirements of the trolley-type gate hoist. On this "restricted working surface", how to achieve precise alignment, stable splicing and integrated assembly of disassembled parts has become a core technical problem that urgently needs to be solved, further increasing the complexity of the installation operation and the construction risk. Summary of the Invention

[0005] This invention provides an installation system and method for installing trolley-type gate hoists in caves, to solve the technical problem in the prior art that it is difficult for high-altitude installation platforms to achieve precise alignment, stable splicing and integrated assembly of disassembled trolley-type gate hoists.

[0006] This invention is achieved through the following technical solution: An installation system for installing a trolley-type gate hoist inside a cavern includes a top anchor assembly and a sliding platform; The hoisting point of the anchor assembly is located in the vertical space corresponding to the track beam, and is used to hoist the components of the trolley-type gate hoist. The sliding platform is mounted on the track of the track beam; the sliding platform can be moved to below the hoisting point of the anchor assembly to support the components of the trolley-type gate hoist that are hoisted to the top of the track beam by the anchor assembly.

[0007] To better realize the present invention, further optimizations are made to the above structure, wherein the sliding platform includes a moving trolley and two sets of assembly platforms; The mobile trolley is mounted on the track of the track beam; Both assembly platforms are slidably mounted on the support surface of the mobile trolley, and the two assembly platforms can fit together.

[0008] To better realize the present invention, the above structure is further optimized by providing two sets of hydraulic cylinders on the mobile trolley. Both sets of hydraulic cylinders are located on the support surface of the mobile trolley and are arranged close to both sides of the mobile trolley; the telescopic ends of the two sets of hydraulic cylinders are respectively connected to the two sets of assembly platforms.

[0009] To better realize the present invention, further optimizations are made to the above structure, wherein the anchor assembly includes a winch, an anchor bolt, an anchor fixing plate, and a pulley system; The anchor bolts are fixed to the top wall of the tunnel above the track beam; The anchor fixing plate is installed at one end of the anchor rod; The pulley system includes a fixed pulley block and a movable pulley block; the fixed pulley block is mounted on the anchor plate; the movable pulley block is equipped with hooks. The winch is set up on the ground of the cavern. One end of the wire rope on the winch is successively fitted with a fixed pulley block and a movable pulley block and then fixed to the movable pulley block.

[0010] An installation method for installing a trolley-type gate hoist inside a tunnel, the method being implemented using the aforementioned installation system for installing a trolley-type gate hoist inside a tunnel, includes the following steps: The trolley-type gate hoist is divided into an upstream trolley frame, a downstream trolley frame, a traveling device, and auxiliary components. The upstream and downstream trolley frames are positioned below the track beam, and then, using the anchor assembly, they are sequentially hoisted onto the sliding platform; or, The downstream and upstream trolley frames are sent to the bottom of the track beam, and the downstream and upstream trolley frames are hoisted onto the sliding platform in sequence using the anchor assembly; The upstream and downstream trolley frames are assembled into the main body of the gate hoist on the sliding platform. The auxiliary components are sent to the bottom of the track beam, and the auxiliary components are hoisted onto the sliding platform using the anchor assembly and installed onto the hoist body; The traveling device is sent to the bottom of the track beam, and the traveling device is hoisted onto the track using the anchor assembly. The main body of the hoist, which is equipped with auxiliary components, is then hoisted onto the traveling device and fixed to it.

[0011] Compared with the prior art, the present invention has the following advantages: The installation system for installing a trolley-type gate hoist in a tunnel provided by this invention includes a top anchor system that can hoist multiple components of the trolley-type gate hoist onto a sliding platform in stages. The sliding platform is used to adjust the positions of multiple components, and precise alignment, stable splicing, and integrated assembly of the trolley-type gate hoist components are performed on the sliding platform. This solves the problem of difficulty in assembling the trolley-type gate hoist on the "restricted working surface" of the track beam, thereby reducing the installation difficulty and construction risk of the trolley-type gate hoist.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] In the description of this invention, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element 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 the invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] In the embodiments of this application, such as Figures 1 to 7 As shown, this installation system can be used for the installation of a trolley-type gate hoist 3 inside a tunnel. It includes a top anchor assembly 1 and a sliding platform 2. See [link / reference]. Figure 1 ;in, The hoisting point of the anchor assembly 1 is located in the vertical space corresponding to the track beam 4, and is used to hoist the components of the trolley-type gate hoist 3 so as to hoist the components of the trolley-type gate hoist 3 above the track beam 4. The sliding platform 2 is moved and set on the track of the track beam 4; the sliding platform 2 can be moved to the lower part of the hoisting point of the anchor assembly 1 to support the components of the trolley-type gate hoist 3 that are hoisted to the top of the track beam 4 by the anchor assembly 1.

[0025] Before installing the trolley-type gate hoist 3, the operators can disassemble the trolley-type gate hoist 3 into several smaller parts. Specifically, the trolley-type gate hoist 3 is disassembled into an upstream trolley frame 31, a downstream trolley frame 32, a traveling device 33, and auxiliary components. The auxiliary components include drums, reducers, brakes, and other auxiliary devices. Then, the components of the trolley-type gate hoist 3 are transported to the underside of the track beam 4 by a flatbed truck, and the components are hoisted onto the sliding platform 2 in stages using the anchor assembly 1. Specifically, when hoisting the components, the operators can first move the sliding platform 2 along the length of the track to one end of the track, so that the hoisting point of the anchor assembly 1 can extend through the hole on the track beam 4 to the ground of the cavern, which facilitates the anchor assembly 1 to hoist the components of the trolley-type gate hoist 3 and hoist the components of the trolley-type gate hoist 3 onto the top of the track beam 4. Subsequently, the sliding platform 2 is moved to the position directly below the hoisting point of the anchor assembly 1, that is, directly below the components of the trolley-type gate hoist 3 that are hoisted by the anchor assembly 1; then the anchor assembly 1 slowly lowers the components of the trolley-type gate hoist 3 so that the components of the trolley-type gate hoist 3 fall onto the sliding platform 2, and the connection between the anchor assembly 1 and the components of the trolley-type gate hoist 3 is released. Repeat the above steps to hoist all the components of the trolley-type gate hoist 3 onto the sliding platform 2 and assemble them on the sliding platform 2. This solves the problem of difficulty in assembling the trolley-type gate hoist 3 on the "restricted working surface" of the track beam 4, thereby reducing the installation difficulty of the trolley-type gate hoist 3 and reducing construction risks.

[0026] It is worth noting that before using the anchor assembly 1 for hoisting, the anchor assembly 1 needs to be inspected and subjected to load tests. The inspection includes weld strength, penetrant testing (PT) after welding, defects such as cracks and porosity, and whether there is jamming or abnormal noise during the no-load test run of the anchor assembly 1. After the inspection is completed, a 125% static load test must be carried out on the anchor assembly 1. The specific operation method is as follows: slowly lift the test weight to 100mm above the ground and hold it for 30 minutes. Observe the deformation of the anchor system, the condition of the weld, the stress of the wire rope and the stability of the pulley block. It can be put into use only after there is no abnormal settlement or deformation.

[0027] In some embodiments, the sliding platform 2 described above includes a mobile trolley 21 and two assembly platforms 22, see [link to documentation]. Figure 4 ;in, The mobile trolley 21 includes a support frame and rollers. The rollers are rotatably mounted at the bottom of the support frame, and the support frame is mounted on the track of the track beam 4 via the rollers, so that the mobile trolley 21 can slide along the length of the track. Both sets of assembly platforms 22 are slidably mounted on the support surface of the mobile trolley 21, and the two sets of assembly platforms 22 can fit together. In this embodiment, the sliding direction of the assembly platform 22 is perpendicular to the length direction of the track, that is, the sliding direction of the assembly platform 22 is perpendicular to the travel direction of the mobile trolley 21. When hoisting the main components of the gate hoist, the two components that need to be spliced ​​can be hoisted onto the two sets of assembly platforms 22 respectively. By sliding the two sets of assembly platforms 22, the two sets of assembly platforms 22 are brought closer to each other and fit together, so as to complete the precise alignment and stable splicing of the two components, thereby reducing the installation difficulty of the trolley-type gate hoist 3.

[0028] Preferably, the aforementioned mobile trolley 21 is equipped with two sets of hydraulic cylinders 23, see [reference]. Figure 4 ; Both sets of hydraulic cylinders 23 are located on the support surface of the mobile trolley 21 and are arranged close to both sides of the mobile trolley 21. The telescopic ends of the two sets of hydraulic cylinders 23 are respectively connected to the two sets of assembly platforms 22. The hydraulic cylinders 23 push and pull the two sets of assembly platforms 22 to move, so as to make the installation of the trolley-type gate hoist 3 more convenient.

[0029] In some embodiments, the above-described anchor assembly 1 includes a winch 11, an anchor bolt 12, an anchor fixing plate 13, and a pulley system 14. See [link to documentation]. Figure 1 , Figure 2 and Figure 3 ;in, Anchor bolt 12 is fixed on the top wall of the tunnel above the track beam 4. When fixing anchor bolt 12, the length and number of anchor bolt 12 should be selected according to the heaviest component in the trolley-type hoist 3, so that the bearing capacity of the anchor system is not less than 3 times the weight of the heaviest component. The anchor fixing plate 13 is installed at one end of the anchor rod 12. Specifically, the anchor fixing plate 13 is fixed to the end of the anchor rod 12 that is exposed at the top of the tunnel. See [reference needed]. Figure 2 and Figure 6 When fixing, the surface of the joint must be cleaned of oil and rust, and the height of the weld should not be less than the diameter of the anchor rod 12; Pulley system 14 includes a fixed pulley block 141 and a movable pulley block 142, see [link / reference] Figure 2 and Figure 7 The fixed pulley block 141 is mounted on the anchor fixing plate 13; the movable pulley block 142 is equipped with hooks. The winch 11 is installed on the ground of the cavern. One end of the wire rope on the winch 11 is successively fitted with a fixed pulley block 141 and a movable pulley block 142 and then fixed to the movable pulley block 142. By releasing the wire rope through the winch 11, the distance between the movable pulley block 142 and the fixed pulley block 141 can be increased, that is, the movable pulley block 142 can be lowered, so as to facilitate the hoisting of the components of the trolley-type gate hoist 3 located on the ground of the cavern. After the connection between the hook and the components of the trolley-type gate hoist 3 is completed, the wire rope can be wound up by the winch 11, the distance between the movable pulley block 142 and the fixed pulley block 141 is reduced, that is, the movable pulley block 142 is raised, and the components of the trolley-type gate hoist 3 on the hook are hoisted to the top of the track beam 4.

[0030] It is worth noting that the aforementioned fixed pulley assembly 141 consists of multiple fixed pulleys coaxially connected, and the aforementioned movable pulley assembly 142 consists of multiple movable pulleys coaxially connected. See [reference needed]. Figure 7 One end of the wire rope is sequentially wound from left to right around the first fixed pulley in the fixed pulley block 141 and the first movable pulley in the movable pulley block 142, until the last fixed pulley is wound around it. Then, it extends and is fixed on the bracket of the movable pulley block 142, thus completing the connection of the pulley system 14. The number of fixed pulleys in the fixed pulley block 141 is one more than the number of movable pulleys in the movable pulley block 142. The fixed pulley in the fixed pulley block 141 and the movable pulley in the movable pulley block 142 are both provided with grooves on their circumferential sidewalls. The depth of the grooves is not less than the diameter of the wire rope, so as to limit the wire rope and prevent it from sliding along the axis of the fixed pulley and / or the movable pulley during the hoisting process, thereby reducing the safety hazards during the hoisting process.

[0031] Preferably, guide wheels are provided on the ground and / or on the track beam 4, see [reference]. Figure 1 One end of the wire rope can be bypassed by the guide wheel and extended to the pulley system 14. The guide wheel changes the direction of the wire rope to better adapt to the narrow space in the cavern.

[0032] Furthermore, this embodiment also provides an installation method for installing a trolley-type gate hoist inside a tunnel. This method is implemented using the aforementioned installation system for installing a trolley-type gate hoist inside a tunnel, and includes the following steps: The trolley-type gate hoist 3 is divided into an upstream trolley frame 31, a downstream trolley frame 32, a traveling device 33, and auxiliary components; The upstream trolley frame 31 and the downstream trolley frame 32 are sent to the bottom of the track beam 4, and the upstream trolley frame 31 and the downstream trolley frame 32 are hoisted onto the sliding platform 2 in one go using the anchor assembly 1. Specifically, the sliding platform 2 is first moved to one end of the track so that the hoisting point of the anchor assembly 1 can extend through the track beam 4 to the ground of the cavern, which facilitates the hoisting of the upstream trolley frame 31 or the downstream trolley frame 32 by the anchor assembly 1. The upstream trolley frame 31 or the downstream trolley frame 32 is hoisted to a position 0.5m above the track beam 4 and suspended. After confirming that there is no shaking, the sliding platform 2 is moved to a position directly below the anchor assembly 1. The anchor assembly 1 is then used to slowly lower the hoisted upstream trolley frame 31 or the downstream trolley frame 32 onto one of the assembly platforms 22 in the sliding platform 2. After the upstream trolley frame 31 or the downstream trolley frame 32 is placed, the sliding platform 2 is moved to one end of the track again. Send the downstream trolley frame 32 or the upstream trolley frame 31 to the bottom of the track beam 4, and use the anchor assembly 1 to hoist the downstream trolley frame 32 or the upstream trolley frame 31 onto the sliding platform 2. Specifically, the hoisting point of the anchor assembly 1 extends through the track beam 4 to the ground of the cavern, which facilitates the hoisting of the downstream trolley frame 32 or the upstream trolley frame 31 by the anchor assembly 1. The downstream trolley frame 32 or the upstream trolley frame 31 is hoisted to a position 0.5m above the track beam 4 and suspended. After confirming that there is no shaking, the sliding platform 2 is moved to a position directly below the anchor assembly 1. The anchor assembly 1 is then used to slowly lower the hoisted upstream trolley frame 31 or the downstream trolley frame 32 onto another assembly platform 22 in the sliding platform 2. Two sets of hydraulic cylinders 23 push two sets of assembly platforms 22 respectively to achieve precise docking of the upstream trolley frame 31 and the downstream trolley frame 32, and assemble the upstream trolley frame 31 and the downstream trolley frame 32 into the main body of the hoist on the sliding platform 2. Move the sliding platform 2 to one end of the track again, send the auxiliary components below the track beam 4, use the anchor assembly 1 to hoist the auxiliary components above the track beam 4, then move the sliding platform 2 directly below the anchor assembly 1, use the anchor assembly 1 to slowly lower the hoisted auxiliary components onto the sliding platform 2, and have the operators install the auxiliary components onto the hoist body; at the same time, move the sliding platform 2 to one end of the track. The traveling device 33 is positioned below the track beam 4. Using the anchor assembly 1, the traveling device 33 is hoisted onto the track. The hoist body with its auxiliary components is then hoisted to a position 0.8m above the track beam 4 and suspended. Simultaneously, the positions of the sliding platform 2 and the traveling device 33 are exchanged, ensuring the traveling device 33 is directly below the hoist body with its auxiliary components. The hoist body with its auxiliary components is then slowly lowered using the anchor assembly 1. Operators adjust the position of the hoist body with its auxiliary components to ensure it accurately lands on the traveling device 33. Finally, the hoist body is secured to the traveling device 33 with bolts. (See attached diagram.) Figure 5 The installation of the trolley-type gate hoist 3 is completed in such a way that the installation time can be controlled within 30 minutes, reducing the time that the main body of the gate hoist with auxiliary components is suspended in the air, thereby improving the installation efficiency of the trolley-type gate hoist 3 and reducing the difficulty of installation and safety hazards during the installation process.

[0033] This installation method is fully adapted to the "small and compact" spatial characteristics of caverns, and can adapt to various complex terrain conditions. It completely breaks through the limitations of the narrow space of caverns and solves the core pain points of traditional solutions such as "cannot enter or lift". It also solves the problem of the high installation difficulty of trolley-type hoist 3 in caverns.

[0034] In the existing technology, the three sets of trolley-type gate hoists are assembled on the ground. Subsequently, the entire trolley-type gate hoist 3 needs to be transported to the high-altitude installation platform (track beam 4). During the transportation process in the narrow passage of the cave, accidents such as equipment collision with the rock wall and slippage due to loss of balance are very likely to occur. Moreover, the large suspended area of ​​the equipment during the overall hoisting makes it more susceptible to the effects of wind and operational errors, resulting in extremely high safety risks.

[0035] In this embodiment, the installation method adopts the mode of "component hoisting + high-altitude mobile platform assembly", which reduces the volume of the required hoisting parts, keeps the weight controllable, and greatly reduces the swaying amplitude during hoisting. At the same time, the sliding platform 2 can bear a load of 40 tons to meet the installation requirements of the trolley-type gate hoist 3.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
