Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, specifically a heat treatment placement rack for the production of shield tail brushes for tunnel boring machines. Background Technology

[0002] A shield tunnel boring machine, or shield machine for short, is a special engineering machine for tunnel excavation. The existing shield tail brush mainly consists of three parts: a protective plate made of steel plate, a clamping plate, and a wire brush made of stainless steel. The wire brush is installed between the protective plate and the clamping plate. The protective plate, the clamping plate, and the wire brush are fixed to the base plate of the shield tail by pins.

[0003] According to the patent application published on the Internet, a heat treatment placement rack for the production of shield tail brushes for tunnel boring machines (authorization announcement number: CN214643543 U) is described as follows: "This utility model belongs to the field of shield machine technology, and relates to shield tail brush production equipment. It proposes a heat treatment placement rack for the production of shield tail brushes for tunnel boring machines, including legs, transverse groove plates, longitudinal groove plates, and multiple pairs of spaced-apart limiting support components. The limiting support components include support plates, corner plates, and rows of limiting plates. The rows of limiting plates include several vertically upward limiting strips, which are spaced apart along the length of the row of limiting plates. A protective plate for placing the shield tail brush is placed between adjacent limiting strips. Two hooks are provided on the outer side of the longitudinal groove plate, with the openings of the hooks facing horizontally and opposite to the opening direction of the other hook. This utility model uses an overhead placement method to place the protective plate, which is beneficial for completing heat treatment and cooling operations, and ensures the quality of the protective plate, thereby improving the working performance of the shield tail brush. The design is reasonable, the structure is simple, the practicality is strong, the utilization rate is high, and it is suitable for large-scale promotion."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model uses two pairs of wave-shaped spring plates on the support plate to create a certain gap between the protective plate and the support plate. Applying pressure to the spring plates generates elasticity, causing the protective plate to spring outward a certain distance, thus placing the protective plate in a relatively loose state. However, in actual use, because this device relies solely on gravity for stacking multiple sets of devices during hoisting, it is prone to slippage and other unexpected situations due to changes in the center of gravity during hoisting. Furthermore, the fixed position of the lifting rings can easily lead to interference between the external hoisting wire ropes and the devices during subsequent hoisting processes. Therefore, it is necessary to improve the design of a heat treatment placement rack for the production of shield tail brushes for tunnel boring machines to solve these problems.

[0030] The adjusting hoisting mechanism 6 includes an adjusting component 61 and a hoisting component 62, with the hoisting component 62 located at the end of the adjusting component 61 away from the support platform 1.

[0032] Furthermore, the first bevel gear 612 meshes with the second bevel gear 615, the movable frame 613 is threadedly connected to the first threaded rod 614, and the movable frame 613 is slidably connected to the adjustment box 611, which facilitates a more stable adjustment process.

[0033] Furthermore, the hoisting assembly 62 includes a connecting platform 621, which is fixedly connected to the end of the movable frame 613 away from the support platform 1.

Example

[0035] Based on Embodiment 1, in the prior art, when hoisting multiple sets of devices, stacking is done solely by gravity, which can easily lead to slippage and other unexpected situations due to changes in the center of gravity during hoisting. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problems. Please refer to Embodiment 2. Figure 6-7Furthermore, in conjunction with Embodiment 1, the auxiliary limiting mechanism 7 includes a connecting box 71, which is fixedly connected to the end of the connecting frame 4 away from the support platform 1. A spring 75 is fixedly connected inside the connecting box 71, and a sliding rod 74 is fixedly connected inside the connecting box 71. A sliding plate 72 is fixedly connected to the end of the spring 75 away from the connecting box 71, and a locking block 73 is fixedly connected to the end of the sliding plate 72 away from the spring 75. This facilitates the adjustment of the position of the locking block 73, thereby satisfying the stacking and limiting use of multiple sets of devices and avoiding unexpected situations such as slippage during subsequent heat treatment hoisting.

[0036] Furthermore, the slide plate 72 is slidably connected to the slide rod 74, the slide plate 72 is slidably connected to the connecting box 71, the locking block 73 is slidably connected to the connecting box 71, the locking block 73 is slidably connected to the connecting frame 4, and the support leg 5 has a through groove at the corresponding position of the locking block 73, which facilitates a more stable use.

[0037] In actual operation, when this device is used, the operator first adjusts the size of the protective plate 3 used to place the shield tail brush. The operator moves the support frame 2 and completes the limit installation with the locking bolts. Then, the protective plate 3 is placed on top of the support frame 2 and inserted. The operator then handles the required number of protective plates 3 and selects an appropriate number of this device for stacking. Using a forklift or hoisting equipment, the two sets of devices are stacked. The top support leg 5 is inserted into the bottom connecting frame 4. The operator pulls the sliding plate 72 of the bottom device. Through the movement of the sliding plate 72, in conjunction with the sliding rod 74 and the spring 75, the locking block 73 moves. After the top support leg 5 is inserted into the bottom connecting frame 4, the sliding plate 72 is released. Under the action of the spring 75, the bottom locking block 73 is inserted into the top support. Inside the support leg 5, the two sets of devices are positioned to limit their movement. After stacking, the workers adjust the device according to its center of gravity and the requirements of the hoisting harness. The workers rotate the first bevel gear 612, which, in conjunction with the second bevel gear 615, causes the first threaded rod 614 to rotate inside the adjustment box 611. This, in conjunction with the first limit rod 616, causes the movable frame 613 to move, thereby adjusting the position of the connecting platform 621 and preventing interference between the wire rope and the device due to changes in the center of gravity. The workers then rotate the bidirectional threaded rod 622, which, in conjunction with the second limit rod 625, causes the movable block 623 to move, thereby adjusting the position of the hook 624. This, in conjunction with the external hoisting wire rope and other devices, completes the hoisting requirements of the entire device.
