Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, specifically to an auxiliary installation device for lifting a subway tunnel evacuation platform. Background Technology

[0002] Urban rail transit systems refer to transportation systems that use vehicles running on fixed tracks in cities, primarily for urban passenger transport. Urban rail transit systems typically include subways, light rail, and modern trams. Subways are generally located in underground tunnels. To improve safety within tunnels and facilitate passenger evacuation in emergencies, evacuation platforms must be installed inside the tunnels. Construction of evacuation platforms within tunnels requires installing components onto the tunnel walls. Due to the large number of components—an average of 600 to 700 components per kilometer of tunnel—each steel beam component weighs approximately 36 kg, and the evacuation platform panels weigh 100-150 kg. If components are installed manually, workers would need to lift and hold them for extended periods, leading to fatigue. This not only makes the installation process cumbersome and inefficient but also time-consuming, labor-intensive, and results in high labor costs.

[0003] Utility model patent CN 220376183 U provides an auxiliary installation device for an evacuation platform, including at least one walking mechanism and at least one hoisting mechanism. The top of the walking mechanism is provided with a hoisting beam, which is set at an angle to the walking direction of the walking mechanism. The hoisting mechanism is slidably connected to the hoisting beam.

[0004] However, CN 220376183 U uses a hoisting mechanism for material feeding, which has a low degree of automation and requires workers to connect the components to the hoisting mechanism, making the process cumbersome. To improve the installation and transportation efficiency of the steel beams and platform panels of the tunnel evacuation platform, it is necessary to design and manufacture a small installation and transportation device that can operate inside the tunnel.

[0005] According to one aspect of this utility model, a lifting auxiliary installation device for a subway tunnel evacuation platform is provided, which can cooperate with rails to transport materials, including...

[0006] The frame has several track wheels at the bottom that cooperate with the track, and the upper surface of the frame has a first conveying channel and a second conveying channel that are perpendicular to each other.

[0007] The lifting and feeding mechanism is located on one side of the second conveying channel and is configured to lift and convey materials.

[0008] A first feeding mechanism is located on a first conveying channel, and the first feeding mechanism is configured to convey materials to a second conveying channel.

[0009] The second feeding mechanism is located on the second conveying channel and is configured to convey materials to the lifting feeding mechanism.

[0010] This utility model provides a liftable auxiliary installation device specifically designed for use in tunnels. The device features a chassis with track wheels at its bottom and a lifting and feeding mechanism, a first feeding mechanism, and a second feeding mechanism mounted on the chassis to transport materials. The track wheels drive the chassis to move along the track. After the auxiliary installation device reaches the target location, materials are placed at the first feeding mechanism, which then transports them to the second feeding mechanism, which in turn transports them to the lifting and feeding mechanism, which then delivers them to the target installation point. This auxiliary installation device can also work in conjunction with various feeding devices. The feeding devices transport materials to the first feeding mechanism, achieving automatic feeding and fully automated, seamless feeding. This auxiliary installation device boasts a high degree of automation, facilitating material transport for workers in tunnels. Furthermore, it is highly adaptable to the confined environment of tunnels, improving the installation and transport efficiency of tunnel evacuation platform steel beams and platform panels, and reducing the difficulty of material transport.

[0011] In some embodiments, the first conveying channel includes two parallel first profiles and two parallel first load-bearing frames, with the first profiles mounted on the frame via the first load-bearing frames.

[0012] Therefore, the first conveying channel consists of two parallel profiles, on which materials are conveyed.

[0013] In some embodiments, the first feeding mechanism includes a first mounting frame, a first driving member, and a first conveying mechanism. The first mounting frame is installed between two first load-bearing frames, the first driving member is disposed on the first mounting frame, and the first conveying mechanism is disposed at the driving end of the first driving member.

[0014] Therefore, during the feeding process of the first feeding mechanism, the first driving component drives the first conveying mechanism to lift, the first conveying mechanism contacts the material on the first conveying channel, and the first conveying mechanism conveys the material to the second feeding mechanism; after the operation, the first driving component drives the reset.

[0015] In some embodiments, an inclined section is provided at one end of the first profile, and a plurality of guide rollers are linearly arranged on the inclined section along the extension direction of the inclined section.

[0016] Thus, the material can be fed into the first conveying channel via the guide rollers.

[0017] In some embodiments, the second conveying channel includes two parallel second profiles and two parallel second support frames, with the second profiles mounted on the frame via the second support frames.

[0018] Therefore, the second conveying channel consists of two parallel profiles on which materials are conveyed.

[0019] In some embodiments, the second feeding mechanism includes a second mounting frame, a second driving member, and a second conveying mechanism. The second mounting frame is installed between two second load-bearing frames, the second driving member is disposed on the second mounting frame, and the second conveying mechanism is disposed at the driving end of the second driving member.

[0020] Therefore, during the feeding process of the second feeding mechanism, the second driving component drives the second conveying mechanism to lift, the second conveying mechanism contacts the material on the second conveying channel, and the second conveying mechanism conveys the material to the lifting feeding mechanism; after operation, the second driving component drives the reset.

[0021] In some embodiments, a lifting auxiliary installation device for a subway tunnel evacuation platform further includes a guide mechanism located at the bottom of the frame, on one side of one of the track wheels, and the guide mechanism abutting against the track.

[0022] Therefore, the guiding mechanism can guide the movement direction of the auxiliary installation device, ensuring that the auxiliary installation device can move along the track.

[0023] In some embodiments, the guiding mechanism includes a swing plate, a swing guide wheel, a mounting base, and two symmetrically distributed guide wheel assemblies. The swing plate is mounted to the side of the frame via a hinge assembly. The swing guide wheel is located at the lower end of the swing plate. The mounting base is located at the bottom of the swing plate. The two guide wheel assemblies are respectively located on both sides of the bottom of the mounting base.

[0024] The swing guide wheel abuts against the upper surface of the track, and the working ends of the two guide wheel assemblies abut against the two sides of the track respectively.

[0025] Therefore, the oscillating guide wheel abuts against the upper surface of the track, and the vertical gravity of the oscillating guide wheel allows the mechanism to make adaptive deflection in the horizontal plane, ensuring constant contact between the guide wheel assembly and the side of the track, thereby ensuring the guiding operation of the guide wheel assembly; the symmetrically distributed guide wheel assembly forms a two-way constraint mechanism, and when there is a lateral offset from the track, this structure can ensure that the guiding mechanism can achieve self-correction in a powerless state, ensuring the stable operation of the guiding mechanism.

[0026] In some embodiments, the guide wheel assembly includes a mounting block, a mounting rod, a buffer spring, and a guide wheel. The mounting block is disposed on a mounting base, the mounting rod is disposed on the mounting block, the buffer spring is sleeved on the mounting rod and acts between the mounting block and the mounting rod, and the guide wheel is rotatably disposed at the lower end of the mounting rod, with the guide wheel abutting against the side of the track.

[0027] Therefore, the guide wheel assembly adopts an elastic connection design, and the dynamic compensation mechanism of the buffer spring can adaptively adjust the undulation of the contact surface, effectively maintaining the operational stability of the guiding mechanism under complex working conditions. This structural design absorbs impact energy through multi-directional buffering, significantly reducing the dynamic load caused by track irregularities and ensuring that the guiding mechanism always maintains precise alignment.

[0038] In this embodiment, the frame 100 is provided with a panel, and the surface of the panel is covered with anti-slip material to ensure that the material does not slip during transportation.

[0039] Combination Figure 3 The first conveying channel 120 includes two parallel first profiles 121 and two parallel first support frames 122.

[0041] During the feeding process of the first feeding mechanism 300, the first driving component 320 drives the first conveying mechanism 330 to lift, and the first conveying mechanism 330 contacts the material a on the first conveying channel 120. The first conveying mechanism 330 conveys the material a to the second feeding mechanism 400. After the operation, the first driving component 320 drives the reset.

[0046] To meet the requirements for lightweight and modular disassembly / assembly of the trolley during tunnel construction, while maintaining the functionality and performance of the equipment, this auxiliary installation device will use lightweight materials and optimize the structure to keep the total weight of the trolley below 150 kg. It can be disassembled into three main modules for easy worker transport and on-site operation. In this embodiment, the first profile 121, the second profile 131, the first load-bearing frame 122, and the second load-bearing frame 132 are all made of aluminum profiles or the main body is composed of aluminum profiles. The first profile 121 and the second profile 131 are made of 6061 aluminum alloy with a wall thickness of 3 mm. Modular disassembly / assembly is achieved through bolt connections, keeping the overall weight within the range of 120-150 kg.

[0047] This auxiliary installation device is equipped with a manual system and a mechanical speed limiter to control the maximum speed of the trolley and ensure transportation safety. In other embodiments, this auxiliary installation device can also be equipped with an electric system, which is a variable speed motor that drives the track wheel 110 to rotate, thereby assisting the auxiliary installation device in providing speed selection under different working conditions.

[0048] In this embodiment, the lifting and feeding mechanism 200 is a lifting platform with translation function. This lifting platform is a common transportation machine in the field and will not be described in detail.

[0049] Combination Figure 5 , Figure 6The guiding mechanism 500 includes a swing plate 510, a swing guide wheel 520, a mounting base 530, and two symmetrically distributed guide wheel assemblies 540.

The swing guide wheel 520 abuts against the upper surface of the track, and the working ends of the two guide wheel assemblies 540 abut against the two sides of the track. The guiding mechanism 500 can hold the track in place to prevent the trolley from tipping over when excessively heavy materials are placed on the right end.

[0050] Furthermore, the swing guide wheel 520 abuts against the upper surface of the track, and the vertical force of the swing guide wheel 520 allows the mechanism to make adaptive deflection in the horizontal plane, ensuring constant contact between the guide wheel assembly 540 and the side of the track, thereby ensuring the guiding operation of the guide wheel assembly 540; the symmetrically distributed guide wheel assemblies 540 form a two-way constraint mechanism, and when there is a lateral offset from the track, this structure can ensure that the guide mechanism 500 can achieve self-correction in a powerless state, ensuring the stable operation of the guide mechanism 500.

[0054] The braking system can be a lightweight mechanical braking mechanism, primarily mounted on the wheels, to ensure the trolley does not move unexpectedly when stationary. It features manual lever control with a self-locking function for easy and safe operation. In case of emergency, the worker can activate the emergency braking mechanism with a single button to immediately lock all wheels.

[0055] The chassis 100 is equipped with an adjustable limiting mechanism to ensure that the steel beams and platform plates do not slip or shift during transportation.
