Technical Field

[0001] This utility model relates to the technical field of tunnel boring machine (TBM) construction machinery and equipment, and in particular to an adjustable rain shelter for a TBM trolley. Background Technology

[0002] The existing rain shelter for tunnel boring machines (TBMs) is a sliding type. The sliding rain shelter covers the outside of the TBM and does not contact the TBM. Support columns are installed at the bottom of the rain shelter frame, and pulleys are added to the bottom of the support columns to facilitate movement on the ground. The rain shelter needs to be manually moved after the TBM is unloaded.

[0003] Sliding rain shelters have the following disadvantages:

[0004] ① The rain shelter is quite heavy, making it difficult to move;

[0005] ②After the trolley is unloaded, the rain shelter needs to be moved manually, which is quite limiting and time-consuming. Utility Model Content

[0006] The main purpose of this utility model is to provide an adjustable rain shelter for tunnel boring machines to solve the above-mentioned problems.

[0007] To achieve the above objectives, this utility model provides an adjustable shield tunnel trolley rainproof canopy, including a canopy, a frame, and fixed lugs. The canopy is located at the top of the frame, and the fixed lugs are located at the bottom of the frame. The fixed lugs are fixedly connected to the trolley lifting lugs.

[0008] Furthermore, the shed is composed of multiple evenly arranged triangular supports, which are connected by crossbeams.

[0009] Furthermore, the triangular support consists of two inclined beams and a bottom beam.

[0010] Furthermore, a support beam is also provided between the inclined beam and the bottom beam.

[0011] Furthermore, it also includes two sets of adjustable components. The adjustable components include a slide beam with two fixed lugs and two L-shaped fixed seats slidably disposed on the slide beam. The fixed lugs are fixedly connected to the trolley lifting lugs, and the L-shaped fixed seats are fixedly connected to the bottom of the frame.

[0012] Furthermore, two L-shaped fixing seats are symmetrically arranged, and the slots of the two L-shaped fixing seats are arranged opposite each other; the L-shaped fixing seat includes a support column, the bottom of the support column is provided with a first sliding sleeve adapted to the sliding beam, the top of the support column is provided with a pressure plate protruding outside the support column, the pressure plate is provided with a first screw hole, and a first clamping bolt is screwed into the first screw hole.

[0013] Furthermore, the fixed lug includes a second sliding sleeve adapted to the sliding beam. The top of the second sliding sleeve is provided with a second screw hole, and a second clamping bolt is screwed into the second screw hole. Both sides of the second sliding sleeve are provided with lugs, and the lugs are provided with through holes corresponding to the lug holes of the trolley.

[0014] Furthermore, the roof is made of corrugated steel sheets.

[0015] Furthermore, the scaffolding is made of square steel tubing.

[0016] Furthermore, the top of the canopy is equipped with canopy hangers.

[0017] This utility model has the following beneficial effects:

[0018] This utility model is fixed to the lifting lug of the trolley, moving together with the trolley during transport, eliminating the need for secondary relocation of the rain canopy and saving labor costs. The adjustable components allow the fixed lug to move freely within a certain range, adjusting to different trolley lifting lug positions to accommodate trolleys of varying sizes. It is simple to operate and highly reliable. Attached Figure Description

Detailed Implementation

[0028] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.

[0029] As attached Figure 1-8 As shown, this utility model provides an adjustable rain shelter for a tunnel boring machine (TBM) trolley, including a canopy 1, a frame 3, and fixed lugs 43. The canopy 1 is made of corrugated steel sheet, and the frame 3 is made of square steel pipe. The canopy 1 is located at the top of the frame 3, and the fixed lugs 43 are located at the bottom of the frame 3. The fixed lugs 43 are fixedly connected to the lifting lugs of the TBM trolley. When the TBM is being moved, the rain shelter moves with the TBM, eliminating the need for secondary movement of the rain shelter and saving labor costs.

[0030] In another embodiment, the shed 3 is composed of a plurality of evenly arranged triangular supports 31, which are connected by crossbeams 32. Each triangular support 31 is composed of two inclined beams 312 and a bottom beam 311. A support beam 313 is also provided between the inclined beams 312 and the bottom beam 311 to improve stability.

[0031] In another embodiment, two sets of adjustable components 4 are also included. The adjustable components 4 include a slide beam 41, on which two fixed lugs 43 and two L-shaped fixed seats 42 are slidably disposed. The fixed lugs 43 are fixedly connected to the trolley lifting lugs, and the L-shaped fixed seats 42 are fixedly connected to the bottom of the frame 3. Two L-shaped fixing seats 42 are symmetrically arranged, with their slots facing each other. Each L-shaped fixing seat 42 includes a support column 423. The bottom of the support column 423 is provided with a first sliding sleeve 424 that is adapted to the sliding beam 41. The top of the support column 423 is provided with a pressure plate 422 that protrudes from the outside of the support column 423. The pressure plate 422 is provided with a first screw hole 425, and a first clamping bolt 421 is screwed into the first screw hole 425. In use, the L-shaped fixing seat 42 is clamped onto the bottom beam 311 of the triangular bracket 31, so that the bottom beam 311 is located between the pressure plate 422 and the sliding beam 41. Then, the first clamping bolt 421 is tightened to press the bottom beam 311, thus completing the fixing of the sliding beam 41. The fixed lug 43 includes a second sliding sleeve 434 adapted to the sliding beam 41. The top of the second sliding sleeve 434 is provided with a second screw hole 435, into which a second clamping bolt 431 is screwed. Both sides of the second sliding sleeve 434 are provided with lug plates 432, each lug plate 432 having a through hole 433 corresponding to the trolley lifting lug hole. In use, the fixed lug 43 is aligned with the trolley lifting lug, ensuring the trolley lifting lug hole aligns with the through hole 433. Then, a fixing pin is inserted for fixation, and the second clamping bolt 431 is tightened to fix the fixed lug 43 to the sliding beam 41. The adjustable component allows the fixed lug to move freely within a certain range, adjusting according to the position of the trolley lifting lug to accommodate trolleys of different sizes.

[0032] In another embodiment, the top of the canopy 3 is provided with a canopy lifting lug 2 to facilitate hoisting onto the top of the trolley and fixing it to the trolley lifting lug.
