Description

Technical Field

[0001] The present invention relates to the technical field of waterproof board trolleys, and in particular to a variable-section adjustable waterproof board trolley and an adjustment method thereof. Background Art

[0002] Laying waterproofing panels is a crucial step in tunnel construction, and currently, waterproofing panel trolleys are often used to assist with installation. These trolleys primarily consist of a gantry supporting a curved track. A trolley mechanism drives the waterproofing panels along the curved track, completing the installation process across the entire tunnel section. Because the curved track must adapt to the tunnel's primary support cross-section, changes in tunnel cross-section often necessitate replacing the curved track, or even the entire trolley, to accommodate the changing tunnel cross-section. Summary of the Invention

[0003] The present invention provides a variable-section adjustable waterproof board trolley and an adjustment method thereof. The waterproof board trolley can adjust the arc track to adapt to the construction of waterproof boards with different tunnel sections. No additional large-scale equipment is required during the adjustment process, and the equipment section adjustment work can be completed conveniently and quickly in the tunnel.

[0004] The technical solution adopted to achieve the above-mentioned purpose of the present invention is:

[0005] A variable-section adjustable waterproofing board trolley comprises at least a gantry, an arc-shaped track, and a trolley mechanism. The arc-shaped track comprises two sets, which are respectively connected to the front and rear ends of the gantry and supported at the tunnel section through the gantry. The trolley mechanism straddles the two sets of arc-shaped tracks and drives the waterproofing board to move along the arc-shaped tracks. The arc-shaped track is a split structure, consisting of a middle section located at the top of the tunnel and two sets of side sections symmetrically distributed on both sides of the tunnel.

[0006] Each set of side sections includes more than one side section, and each side section on both sides of the tunnel is symmetrical one to one;

[0007] The connection between the middle section and the side section and between adjacent side sections are connected to a set of detachable extension sections through a set of detachable first pins, and the middle section, the side section and the extension section rotate relative to each other forward and backward along the direction of the waterproof board trolley;

[0008] Each set of extension sections connected to the two sets of side sections are symmetrically arranged;

[0009] Each group of first pins includes more than one first pin arranged along the width direction of the arc track;

[0010] Each group of extension sections includes more than one extension section with the same structure and size. The number and position of the extension sections and the first pins in a group of extension sections and a group of first pins at the same connection point correspond to each other.

[0011] The extension section is an arc-shaped structure, and the radius of the extension section is adapted to the radius of the middle section and the side section, so that the connection between the extension section and the middle section and the side section, as well as the connection between the extension section and the adjacent side section, is smooth;

[0012] A fixed section is connected between the middle section and the side sections at both ends of the lengthened section or between adjacent side sections;

[0013] The middle section is fixedly connected to the mast via a lifting cylinder, and the side sections are connected to the mast via side cylinders;

[0014] The side oil cylinder is connected to the side section and the door frame through a second pin shaft.

[0015] The arc track as a whole comprises two channel steels arranged parallel to each other along the direction of the waterproof board trolley and a connecting rod connected between the two channel steels;

[0016] Each group of first pins is provided with two first pins corresponding to two channel steels;

[0017] Each group of extension sections is provided with two extension sections.

[0018] The fixed section is a long plate-shaped structure, and is fixedly installed on one side of the arc track through ear plates and a third pin shaft provided at both ends of the fixed section.

[0019] The lifting oil cylinder is fixedly connected to the intermediate section and the door frame through flanges.

[0020] The first pin shaft includes a pin hole and a positioning pin, wherein the pin hole on the middle section or the side section is arranged on the lug plate connected to its end, and the pin holes of the extended section are arranged at its two ends.

[0021] The present invention also provides an adjustment method for a variable-section adjustable waterproofing board trolley, comprising the following steps: (1) the waterproofing board trolley is positioned at the tunnel section in an initial state, and if the size of the curved track of the waterproofing board trolley in the initial state matches the size of the tunnel section, the waterproofing board is directly laid;

[0022] (2) If the size of the tunnel section is larger than that of the curved track, enter the adjustment state, empty all the side cylinders and side sections, lift the entire curved track with the jacking cylinder, make the middle section match the top of the tunnel section, and then adjust the side cylinders to connect all the side cylinders and side sections;

[0023] (3) According to the cross-sectional dimensions of the tunnel, a set of extension sections of appropriate size is selected. By connecting the extension sections between the side sections and the middle sections, the sizes of the side sections and the middle sections on the left or right side of the tunnel are adjusted. The specific steps are as follows:

[0024] (3.1) Unlock a first pin at the connection between the middle section and the side section. The side cylinder of the side section extends, lifting the side section and causing the side section to rotate around the other first pin, thus forming a space between the side section and the middle section.

[0025] (3.2) Insert an extension section between the released first pins and connect both ends of the extension section to the first pins;

[0026] (3.3) Untie the other first pin at the connection between the middle section and the side section on this side, and the middle section and the side section are connected by the extension section in step (3.2);

[0027] (3.4) The side cylinder of the side section contracts, and the side section rotates until it is aligned with the middle section;

[0028] (3.5) Insert another extension section between the middle section and the side section, and connect the two ends of the extension section to the middle section and the side section through the first pin;

[0029] (4) selecting another set of extension sections symmetrical to the extension sections in step (3), and adjusting the sizes of the side sections and the middle sections on the other side of the tunnel using the method in step (3) so that the adjusted arc track matches the cross-sectional dimensions of the tunnel;

[0030] (5) Fixed sections are installed between the middle sections and side sections on both sides of the tunnel. After the waterproof board trolley is adjusted, the waterproof board is laid.

[0031] The initial state of the waterproof board trolley is: the middle section and side sections of the arc track and the adjacent side sections are directly connected through the first pin shaft, the lifting cylinder is connected to the middle section, and all the side cylinders are connected to the side sections, so that the entire arc track is supported on the door frame.

[0032] According to the size of the tunnel section, an extension section is connected between the middle section and the side section or / and between adjacent side sections.

[0033] The steps of connecting the lengthened sections between adjacent side sections are the same as the steps of connecting the lengthened sections between the middle section and the side sections. At this time, the upper side section and the middle section are regarded as a whole, which are equivalent to the middle section in step (3) and step (4), and the side sections on the left and right sides of the lower tunnel are equivalent to the side sections in step (3) and step (4) respectively.

[0034] When the size of the new construction tunnel section becomes smaller, the waterproof board trolley will remove or replace the extension section in the curved track with an extension section of a new size according to the size of the new construction tunnel section, so that the curved tunnel matches the size of the new tunnel section.

[0035] Compared with the existing technology, the technical solution provided by the present invention has the following advantages: 1. The waterproof board trolley provided by the present invention is supported and extended by the lifting cylinder and the side cylinder to connect the extension section to the split arc track, so as to adjust the size of the arc track to adapt to the construction of waterproof boards in different tunnel sections, and no additional large equipment is required during the adjustment process, and the equipment section adjustment work can be completed conveniently and quickly in the tunnel.

[0036] 2. When the waterproof board trolley provided by the present invention encounters a situation where the tunnel section changes, there is no need to manufacture a new curved track. It only needs to design an extension section and a fixed section according to the new tunnel section, which saves costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the following embodiments.

[0047] The structure of the variable cross-section adjustable waterproof board trolley provided by the present invention is as follows Figure 1 As shown, it at least includes a gantry 2, an arc track and a trolley mechanism 3. There are two groups of arc tracks, which are respectively connected to the front end and the rear end of the gantry and supported at the tunnel section 1 through the gantry. The trolley mechanism sits astride the two groups of arc tracks and drives the waterproof board to move along the arc track, thereby completing the laying of the waterproof board.

[0048] The arc track in the present invention is a split structure, which is composed of an intermediate section 4 at the top and two groups of side sections 5 symmetrically distributed at both ends of the intermediate section. Specifically, each group of side sections includes more than one side section, and each side section on both sides of the tunnel is symmetrical one by one, ensuring that the number and position of the side sections on both sides of the tunnel correspond. That is, if there are two side sections on the left side of the tunnel, there are also two side sections on the right side of the tunnel, and the two side sections on both sides of the tunnel are symmetrical one by one, which is convenient for the adjustment of the arc track in the later stage. In this embodiment, each group of side sections only includes one side section, that is, the arc track includes one intermediate section and two side sections, see Figure 1 .

[0049] The middle section is fixedly connected to the gantry through the lifting cylinder 6, and the side sections are connected to the gantry through the side cylinders 7; specifically, the lifting cylinder is fixedly connected to the middle section and the gantry through flanges, and after the flange connection, the lifting cylinder and the middle section remain relatively fixed; the side cylinders are connected to the side sections and the gantry through a second pin shaft, which is convenient for the later adjustment of the arc track. In addition, each middle section or side section is connected to the gantry through more than one lifting cylinder and side cylinder.

[0050] In the initial state, the connections between the middle section and the side sections and between adjacent side sections are directly connected through a set of detachable first pins 8, the lifting cylinder is connected to the middle section, and all the side cylinders are connected to the side sections, so that the entire arc track is supported on the door frame, making the entire waterproof board trolley a rigid whole. Specifically, the setting of the detachable first pins allows the middle section and the side sections and the adjacent side sections to rotate relative to each other forward and backward along the direction of the waterproof board trolley, and can be disassembled during the adjustment process. Furthermore, each set of first pins includes more than one first pin arranged along the width direction of the arc track. In the initial state, there is no extension section connected to the arc track, so the size of the arc tunnel in the waterproof board trolley is used to adapt to the minimum size of the tunnel section.

[0051] The initial state of the waterproof board trolley is as follows Figure 1 and Figure 2As shown, the arc track in this embodiment includes two channel steels 9 arranged parallel to each other along the direction of the waterproof board trolley and a connecting rod 10 connected between the two channel steels. Therefore, each set of first pins is provided with two first pins corresponding to the two channel steels. Figure 2 , the two channel steels at each connection are connected one by one through the first pin shaft.

[0052] If the size of the curved track of the waterproof board trolley in the initial state matches the size of the tunnel section, the waterproof board can be laid directly without adjusting the curved track. However, if the size of the tunnel section is larger than the size of the curved track, the waterproof board trolley enters the adjustment state. During the adjustment, the waterproof board trolley connects extension sections at the connection between the middle section and the side section and between adjacent side sections to match the size of the curved track with the size of the tunnel section. During actual construction, you can choose to connect extension sections separately between the extension sections and the side sections or between adjacent side sections, or you can choose to connect extension sections between the extension sections and the side sections or between adjacent side sections to meet the changes when the size is larger. However, it is preferred to adjust the size of the curved track by connecting only one set of extension sections when the size change is not large, so as to reduce the number of steps. When the construction of a tunnel section is completed and the size of the new construction tunnel section is reduced, the waterproof board trolley removes or replaces the extension section in the curved track with an extension section of the new size according to the size of the new construction tunnel section, so that the curved tunnel can match the size of the new tunnel section. The extension section allows the curved track to adapt to the construction of tunnel sections of different sizes.

[0053] Specifically, the connections between the middle section and the side sections and between adjacent side sections are connected with a set of detachable extension sections 11 through the first pin shaft, and each set of extension sections connected to the two sets of side sections are symmetrically arranged; that is, each connection of the side sections on both sides of the tunnel (including the side sections and the middle section and the side sections and the side sections) can choose whether to connect the extension sections according to the size of the tunnel section. Each set of extension sections includes more than one extension section with the same structural size, and the number and position of the extension sections and the first pin shafts in a set of extension sections and a set of first pin shafts at the same connection point correspond to each other, so that the extension section can be connected to the middle section or the side section through the pin hole of the first pin shaft. Therefore, in this embodiment, each set of extension sections is correspondingly provided with two extension sections, such as Figure 8 As shown. The extension section is an arc-shaped structure, and the radius of the extension section is adapted to the radius of the middle section and the side section, so that the connection between the extension section and the middle section and the side section, as well as the extension section and the adjacent side section, is smooth, ensuring that the trolley mechanism can move smoothly between the middle section, the extension section, and the side section without jamming. This embodiment provides an adjustment state when the extension section is connected between the middle section and the side section of the waterproof board trolley, as shown in the schematic diagram. Figure 7Specifically, the first pin shaft includes a pin hole and a positioning pin, wherein the pin hole on the middle section or the side section is set on the ear plate connected to its end, and the pin hole of the extension section is set at its two ends.

[0054] A fixed section 12 is connected between the middle section and the side section at both ends of the extension section or between adjacent side sections to prevent the rotation between the segments of the arc track. Specifically, the fixed section is a long plate-shaped structure, and the fixed section is fixedly installed on one side of the arc track through the ear plates and the third pin shaft provided at both ends of the fixed section. Figure 8 shown.

[0055] The present invention also provides a method for adjusting a variable cross-section adjustable waterproofing board trolley, comprising the following steps: (1) the waterproofing board trolley is initially positioned at the tunnel cross section, such as Figure 1 and Figure 2 As shown, if the size of the curved track of the waterproof board trolley in the initial state matches the size of the tunnel section, the waterproof board can be laid directly without adjusting the curved track;

[0056] (2) If the size of the tunnel section is larger than that of the curved track, enter the adjustment state, empty all the side cylinders and side sections, and lift the entire curved track with the jacking cylinder to match the middle section with the top of the tunnel section, such as Figure 3 As shown, adjust the side cylinders and connect all the side cylinders and side joints, as shown in Figure 4 As shown;

[0057] (3) According to the cross-sectional dimensions of the tunnel, a set of extension sections of appropriate size is selected. By connecting the extension sections between the side sections and the middle sections, the sizes of the side sections and the middle sections on the left or right side of the tunnel are adjusted. The specific steps are as follows:

[0058] (3.1) Unlock a first pin at the connection between the middle section and the side section. The side cylinder of the side section extends, lifting the side section and causing the side section to rotate around the other first pin, thus forming a space between the side section and the middle section.

[0059] (3.2) Insert an extension section between the first pins that have been untied, and connect the two ends of the extension section to the first pins, as shown in the following example: Figure 5 and Figure 6 As shown;

[0060] (3.3) Untie the other first pin at the connection between the middle section and the side section on this side, and the middle section and the side section are connected by the extension section in step (3.2);

[0061] (3.4) The side cylinder of the side section contracts, and the side section rotates until it is aligned with the middle section;

[0062] (3.5) Insert another extension section between the middle section and the side section, and connect the two ends of the extension section to the middle section and the side section through the first pin;

[0063] (4) selecting another set of extension sections symmetrical to the extension sections in step (3), and adjusting the sizes of the side sections and the middle sections on the other side of the tunnel using the method in step (3) so that the adjusted arc track matches the cross-sectional dimensions of the tunnel;

[0064] (5) Install fixed sections between the middle section and the side sections on both sides of the tunnel, such as Figure 7 and Figure 8 As shown, the adjustment of the waterproof board trolley is completed, and then the waterproof board is laid.

[0065] The above adjustment method is also applicable to the adjustment step of connecting the extension section between adjacent side sections. At this time, the upper side section and the middle section are regarded as a whole, which are equivalent to the middle section in step (3) and step (4), and the side sections on the left and right sides of the lower tunnel are equivalent to the side sections in step (3) and step (4) respectively.

[0066] In addition, when the adjusted waterproof board trolley enters a tunnel section with a smaller size, it is necessary to remove the extension sections connecting them. When removing the extension sections, it is also necessary to first remove one extension section in each group of extension sections, and then connect the first pin shaft here before taking another extension section, and so on.
