[0002] The assembly of mining TBMs is mainly carried out in underground chambers. Limited by the space of the assembly site, it is necessary to reasonably arrange the assembly sequence and plan the limited site.

[0003] At present, the underground assembly of TBMs mostly adopts gantry cranes (girder cranes, hydraulic jacking gantry cranes) or the method of cable anchor beams + anchor points. When using mechanical equipment such as gantry cranes for equipment assembly, the assembly chamber is huge, and the lifting equipment will occupy the space on both sides of the roadway and cause no effective space on the roof. The cost of purchasing lifting equipment is high and the installation of the lifting equipment is time-consuming. When using a single lifting equipment, multi-point parallel lifting operations cannot be carried out. When assembling by the method of cable anchor beams + anchor points, there are great safety risks in switching anchor points. Summary of the Invention

[0040] In the following, the exemplary solutions of the embodiments of the present invention will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present invention. Unless otherwise defined, the technical terms or scientific terms used in the present invention should have the ordinary meaning understood by those of ordinary skill in the art.

[0041] In the description of the present invention, it should be understood that the expressions "first" and "second" are used to describe various elements of the present invention, and do not represent any limitation of order, quantity or importance, but are only used to distinguish one component from another.

[0042] It should be noted that when there is an expression that an element is "connected", "coupled" or "linked" to another element, it may mean that they are directly connected, coupled or linked, but it should be understood that there may be an intermediate element between the two; that is, it covers the positional relationship of direct connection and indirect connection.

[0043] It should be noted that the use of words such as "a" or "an" does not necessarily imply a limitation on quantity. Words such as "comprising" or "including" mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items.

[0044] It should be noted that terms indicating orientation or positional relationship such as "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships. This is for the convenience of describing the present invention, rather than the device or element being referred to having a specific orientation, being constructed and operated in a specific orientation; when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0045] See Figures 1-6 , a mining TBM assembly device, including an underground chamber 300, top tracks 100, an assembly support unit, and a side-shifting pushing unit. The two top tracks 100 are arranged in parallel on the top of the underground chamber 300. At least one lifting device is provided on each top track 100, and the lifting device can reciprocate along the top track 100; a support base plate 200 is provided at the bottom of the underground chamber 300, and the assembly support unit is slidably arranged on the support base plate 200 in a matching manner. The assembly support unit includes an assembly bracket 201 and a pushing oil cylinder 202 arranged on the side of the assembly bracket 201; a plurality of groups of the side-shifting pushing units are evenly distributed on the support base plates 200 on both sides of the assembly support unit, and the side-shifting pushing units are used to push the assembly support unit to move horizontally on the support base plate 200.

[0046] In the above structure, the underground chamber: provides a space for the assembly of the mining TBM.

[0047] The top tracks: provide a support structure for lifting and moving along the axial direction of the underground chamber, and can cooperate with the lifting device to realize the lifting and axial movement of components.

[0048] The assembly support unit: provides bottom support for the mining TBM, ensuring the stability of the bottom support structure of the mining TBM.

[0049] The side-shifting pushing unit: can enable the assembly support unit to move horizontally, so as to be able to adjust the precise alignment between components.

[0050] Preferably, the lifting device 102 in this embodiment is an electric hoist. In order to facilitate the walking of the lifting device on the top track, a lifting carriage 101 is provided on the top track 100 in this embodiment, and the lifting device 102 is arranged below the lifting carriage 101. The electric hoist is driven by the lifting carriage to realize axial movement, and the electric hoist drives the lifting and lowering of the TBM components.

[0051] Since the two top tracks are arranged symmetrically about the left and right of the underground chamber, in order to facilitate the adjustment of the positions of the components and achieve the alignment of the lifting position and the assembly position, the present application further includes a lifting beam 106. On the one hand, it can overcome the problem that the weight of a single component is too large and exceeds the allowable lifting weight of a single electric hoist. On the other hand, it can locally adjust the lifting position and facilitate the position adjustment according to the different assembly positions of the lifted components. Specifically, both ends of the lifting beam 106 of the present application are hoisted on the two top tracks 100 through lifting carriages 101. Multiple groups of lifting lugs 107 are arranged at the lower part of the lifting beam 106, and at least two groups of lifting devices 102 are arranged at the lower part of the lifting beam 106.

[0052] Further, in order to ensure the effective connection between the top track and the top of the underground chamber, the top track 100 of the present application is an I-beam. The top track 100 is fixedly connected to the top of the underground chamber 300 through an anchoring unit. The anchoring unit includes a fixing plate 103, a connecting vertical plate 104 and a rib plate 105. The fixing plate 103 is arranged on the top of the underground chamber 300 through a fixing cable 108. The top of the connecting vertical plate 104 is fixedly welded to the fixing plate 103 in a fitting manner, and the lower part of the connecting vertical plate 104 is fixedly welded to the top track 100 in a fitting manner. Rib plates 105 are arranged at intervals on both sides of the connecting vertical plate 104, and the upper side and the lower side of the rib plate 105 are respectively welded to the fixing plate 103 and the top track 100. Through the setting of the above structure, the I-beam is stably and fixedly attached to the top of the underground chamber, which can ensure the safety of the construction during the lifting process, and the overall structure occupies a small space area, which is more conducive to reserving sufficient space for the assembly of the TBM.

[0053] In order to properly handle the ground support structure and avoid problems such as local depression of the ground during the assembly of the TBM, and also to facilitate the lateral pushing of the assembly bracket by the side-shifting pushing unit, multiple groups of connecting holes 206 are arranged on the support bottom plate 200 of the present application. The side-shifting pushing unit includes a reaction seat 203 and a transverse shifting oil cylinder 204. The reaction seat 203 is connected and fixed to the support bottom plate 200 through bolts 207 and the connecting holes 206, and the fixed position of the reaction seat can be flexibly adjusted according to different formation requirements. A support pad 205 is arranged at the lower part of the transverse shifting oil cylinder 204. The support pad can play a role in lifting and supporting and adjust the levelness of the transverse shifting oil cylinder. The action end of the transverse shifting oil cylinder 204 is in contact with and supports the assembly bracket 201.

[0054] Furthermore, the assembly bracket 201 in this embodiment includes box girders 2011 located on both sides and cross beams 2012 connected between the two box girders. Support surfaces 2013 are provided at the inner tops of the two box girders 2011. The box girders and the cross beams are arranged in a U-shaped groove structure. The support surfaces can increase the contact area between the outer wall surface of the TBM and the box girders, making the support more stable and avoiding local deformation caused by excessive local stress.

[0055] See Figures 1-6 , this application also discloses a method for assembling a mining TBM. The underground assembly is carried out by using the above-mentioned mining TBM assembly device, and specifically includes the following steps:

[0056] Process the top foundation and bottom foundation of the underground chamber, arrange the top track on the top foundation, and arrange the support bottom plate on the bottom foundation;

[0057] Lift the lifting equipment onto the top track, and arrange the assembly support unit and the side-shifting pushing unit in position on the support bottom plate to complete the debugging of the equipment;

[0058] Transport the mining TBM in blocks according to the assembly sequence. After being transported to the underground chamber, lift it by the lifting equipment, transport it to the assembly area, and assemble it in position on the assembly support unit;

[0059] When there is a lateral deviation between the lifting position and the installation position of the block of the mining TBM to be assembled, push the assembly support unit to move horizontally by the side-shifting pushing unit, and drive the assembled block of the mining TBM to be aligned and installed with the block of the mining TBM to be assembled;

[0060] Normally, lifting can be completed by a single lifting equipment, as Figure 5 shown; when the weight of the block of the mining TBM to be assembled exceeds the allowable lifting weight of a single lifting equipment, multiple lifting equipments lift synchronously. The multiple lifting equipments can be multiple on the same top track, or multiple lifting equipments can be arranged under the lifting beam by setting the lifting beam, as Figure 6 shown;

[0061] After the mining TBM is assembled, push the assembly support unit to move horizontally by the side-shifting pushing unit to align the axis of the mining TBM with the axis of the starting chamber, and push the mining TBM forward by the jacking oil cylinder on the assembly support unit to start the stepping operation.

[0062] This application adopts the lifting method of the ceiling-mounted top track, effectively utilizes the top space, and can reduce the size of the chamber. Through the structural arrangement of the top track and the lifting equipment, the procurement cost of large lifting equipment can be saved, the cost can be saved, and the project cost can be reduced.

[0063] During the hoisting process, according to the weights of different TBM components and the assembly of components at different positions, multiple hoisting devices can be selected for configuration without interference, enabling multi-point parallel operation and shortening the overall assembly period.

[0064] This application can reduce the hook-changing operation, lower the construction risk, and ensure operation safety. Compared with the prior art, this application not only improves the equipment but also further upgrades the construction process, greatly enhancing both the construction efficiency and the construction safety.

However, it should be understood that the functions of these embodiments are only for exemplification and not for limiting the scope, application, or structure of the present invention in any way. The protection scope of the present invention is defined by the appended claims and their equivalents.
