Description

Technical Field

[0001] The utility model relates to the technical field of TBM equipment assembly construction, in particular to a sliding shoe device for stepping a double-shield TBM connecting bridge. Background Art

[0002] During the assembly and construction of TBM equipment, the overall length of the TBM equipment ranges from 170 meters to 400 meters, so the conditions of the TBM assembly construction site are relatively high. However, most construction sites cannot provide such a large assembly site. The TBM main equipment often needs to be slowly moved from the assembly site to the starting face by a stepping device, and the TBM is continuously moved to leave assembly space for the supporting trolley equipment. The TBM main part has a stepping device to assist in movement, and the supporting trolley can be installed on the track to ensure smooth movement. However, the connecting bridge part connected to the TBM main part only has rubber-coated wheels used in the segment holes. The rubber-coated wheels are located on both sides of the connecting bridge and contact the side segments. They cannot provide support when the TBM equipment steps. Therefore, when the TBM equipment steps, the connecting bridge is in a suspended state. How to ensure that the connecting bridge moves smoothly with the TBM equipment is a relatively critical issue.

[0019] like Figure 1-2As shown, the utility model provides a sliding shoe device for stepping a double-shield TBM connecting bridge, comprising a column 1, two support plates 2 symmetrically arranged on the top of the column 1, the two support plates 2 are longitudinally arranged on the side surfaces of the column 1, a bottom plate 5 is provided at the bottom of the column 1, and a plurality of ribs 4 are provided at the bottom of the column 1, each of the ribs 4 is uniformly arranged on the surface of the column 1 longitudinally along the circumference of the column 1, and the bottom of the rib 4 is fixed on the bottom plate 5.

[0020] The utility model provides a sliding shoe device for the stepping of a double-shield TBM connecting bridge. The height of the columns of the sliding shoe device is determined according to the height between the bottom of the TBM connecting bridge and the ground, thereby providing good support for the TBM connecting bridge and ensuring that the connecting bridge moves smoothly and steadily with the TBM equipment.

[0021] At the same time, the ribs 4 on both sides of the column 1 can also play a role of stable support, strengthen the stability of the sliding shoe device provided by the utility model, and ensure that the connecting bridge moves smoothly and steadily with the TBM equipment.

[0022] The column 1 is a square tube. To facilitate the production of the sliding shoe device using local materials at the construction site, the column 1 is composed of two square grooves spliced ​​together. The surface of the column 1 is provided with multiple reinforcement plates 3, which are respectively arranged on the surface of the column 1 and located at the splicing position of the two square grooves.

[0023] To enhance the stability of the support of the sliding shoe device, the present invention provides multiple reinforcing plates 3 on the surface of the column 1, each located on both sides of the column 1. The reinforcing plates 3 on each side are distributed sequentially from top to bottom. At the same time, the number of reinforcing plates 3 on each side is equal.

[0024] The column 1 of the present invention uses a square groove commonly used on construction sites, so that the length can be cut according to actual needs. At the same time, a reinforcing plate is used to strengthen the firmness of the column, making the support more stable.

[0025] In the present invention, the base plate 5 comprises a first base plate and two second base plates. The first base plate is secured to the uprights 1 and ribs 4, while the two second base plates are secured to the left and right sides of the first base plate, respectively. The second base plates are positioned at a predetermined angle relative to the first base plate. Furthermore, a polishing layer 6 is provided at the connection between the second base plates and the first base plate. Typically, the angle between the first and second base plates is 120 degrees.

[0026] In the present invention, the bent bottom plate 5 can protect the rib plate from the outside, play a role in stabilizing the sliding shoe device, thereby better playing a supporting role and ensuring that the connecting bridge moves smoothly with the TBM equipment.

[0027] At the same time, in the present invention, the edge where the bottom of the rib plate 4 is connected to the bottom plate 5 is provided with a polishing layer 6. The polishing layer 6 can ensure the smoothness of the welding corners of the product, and will not touch other people during construction and use, thus ensuring the safety of personnel at the construction site.

[0028] In the present invention, the connection is generally a fixed connection. In actual construction, welding can be used to ensure the stability of the sliding shoe device.

[0029] In the specific project construction, the following steps can be taken:

[0030] Step 1: Based on the current height between the bottom of the TBM bridge and the ground, as well as the size and overall weight of the TBM bridge main beam, determine the number of skid shoes needed and their sizes.

[0031] Step 2: According to the size of the sliding shoe, select appropriate steel plates and steel sections to make corresponding semi-finished parts for easy assembly.

[0032] Step 3: Assemble the semi-finished parts and reinforce them by welding.

[0033] Step 4: Grind the assembled product to remove burrs and welding slag, grind and polish the bottom of the shoe, and grind the bottom weld to a smooth transition to reduce friction.

[0034] Step 5: Apply protective paint to the finished product.

[0035] We take one of the construction sites as an example and complete the construction in the following way:

[0036] 1. Prepare materials: steel plates with thickness δ=12, 20, and channel steel with thickness 20;

[0037] 2. Determine the number of sliding shoes required and their sizes based on the current height between the bottom of the TBM bridge and the ground, as well as the size and overall weight of the TBM bridge's main beam.

[0038] 3. First cut out the semi-finished material, and grind off the burrs and iron oxide, and grind the welding surface clean.

[0039] 4. First, weld the channel steels together to form columns, and then weld several 150*150mm steel plates as reinforcement connecting plates to the channel steel seams;

[0040] 5 After welding is completed, place the column in the center of the 600*600mm steel plate and weld it to reinforce it.

[0041] 6. Weld the 200*600mm steel plate to both ends of the 600*600mm steel plate and form a 30° angle with the ground; polish the bottom weld between the 200*600mm steel plate and the 600*600mm steel plate to make it round and smooth.

[0042] 7. Weld 150mm*150mm triangular steel plates to both ends of the column; weld the remaining semi-finished steel plates around the column.

[0043] 8. Polish the assembled product, remove burrs and welding slag, and apply anti-rust paint.

[0044] 9 During on-site installation, further reinforcement can be performed as needed.

[0045] In summary, the utility model can provide sufficient supporting force for the TBM connecting bridge to prevent deformation of the TBM connecting bridge while ensuring that its own friction force is not large during the stepping process of the TBM connecting bridge device; by welding steel sections and steel plates to form a "slipper device", and welding it to the bottom of the TBM connecting bridge structure, when the TBM equipment steps as a whole, sufficient supporting force is provided for the connecting bridge to prevent deformation of the TBM connecting bridge, and at the same time does not affect the installation of subsequent supporting equipment; the device is simple to manufacture and can be quickly manufactured and put into use according to the height of the bottom of the TBM connecting bridge from the ground.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
