[0002] The functions of large water channels or river channels mainly include water supply, irrigation, ecological environment improvement and economic and social development promotion, which not only ensures the effective utilization of water resources, but also promotes the overall development of the region. In the long-term water running process, the side slope of the water channel or river channel will be affected by many factors such as underground water level, freezing and thawing, construction quality and external force, which may cause cracking, collapse, uplift and anti-floating instability damage of the local concrete lining panel of the water channel or river channel side slope, which has an adverse effect on the structure safety and water supply capacity of the water channel or river channel.

[0003] When repairing the lining panel, it is often necessary to rely on repair equipment. For example, Chinese patent "CN119663855A" discloses "a concrete lining plate repair equipment and method in a running water state", which installs a cutting unit and a dismounting unit on the rotating member of the slide in turn, and through the combination of the telescopic unit and the rotating member, the damaged lining plate can be cut, separated, extracted, transported and the new lining plate can be installed in sequence.

[0004] In the above repair equipment, the walking unit includes two walking frames arranged at the water inlet end and the water outlet end of the truss, and the two walking frames are each provided with a third driving wheel. After the lining plate covering the surface of the truss is repaired, the third driving wheel is used to walk on the channel bottom and the channel bank to drive the truss to change the working position in the river channel or the channel. However, in the assembly operation of the walking unit and the truss, the walking unit needs to be hoisted to the channel bottom first, and then the truss needs to be slid to the channel bottom and connected with the walking unit. Due to the influence of the side slope length and water flow, the accuracy of the connection between the two cannot be guaranteed, manual intervention is needed, and the assembly efficiency is reduced.

DETAILED DESCRIPTION

[0032] The technical solutions in the present application will be further described below with reference to the drawings and embodiments.

[0033] As Figure 1 With Figure 2 As shown in the drawings, the embodiment of the present application proposes a walking type underwater support equipment connected to the water inlet end of the truss 1, used for supporting the truss 1, comprising a cross beam 2 connected to the water inlet end of the truss 1 and a moving mechanism arranged at the bottom of the cross beam 2 along the length direction of the cross beam 2, further comprising:

[0034] Two support seats 6, each of the two support seats 6 is provided with a walking wheel 601, and the driving direction of the walking wheel 601 is perpendicular to the moving mechanism;

[0035] An adjusting mechanism arranged on the side surface of the support seat 6 and connected to the walking wheel 601, used for adjusting the distance between the support seat 6 and the cross beam 2, so as to form a height difference between the walking wheel 601 and the moving mechanism.

[0036] In the embodiment of the present application, the truss 1 is arranged along the channel slope surface, and the truss 1 is often prefabricated on the shore, that is, divided into several truss 1 segments, and the several truss 1 segments are connected to form the truss 1 as a whole. When the truss 1 is connected, the cross beam 2 is hoisted first, and the hoisting mode can be a crane or other hoisting equipment, preferably a winch 8. The present application also includes the winch 8, which is arranged at the water outlet end of the truss 1 and connected to the cross beam 2. The winch 8 is connected to the cross beam 2 through the steel cable arranged therein. The number of winches 8 can be multiple, and the multiple winches 8 are evenly arranged at the water inlet end of the truss 1, so that the lifting points of the cross beam 2 are distributed more evenly, thereby ensuring the stability of the cross beam 2 during hoisting.

[0037] Secondly, the support seat 6 and the walking wheel 601 arranged on the support seat 6 are taken as the support structure of the cross beam 2, in the initial splicing of the truss 1, the cable of the winch 8 is released, the cross beam 2 slides on the channel surface under the rolling of the walking wheel 601, the cross beam 2 is hoisted on the channel surface in the appropriate area close to the channel bank, the length of the appropriate area can depend on the length of the truss 1 segment, facilitating the assembly of the first truss 1 segment and the cross beam 2, in the subsequent splicing process, only the cable of the winch 8 is released to continue to lower the position of the cross beam 2, so that the cross beam 2 continues to slide in the direction of the channel bottom under the action of the support seat 6 and the walking wheel 601 and the gravity of the cross beam 2 itself, until the splicing part of the first truss 1 segment moves to the appropriate area close to the channel bank on the channel surface, that is, the position of the cross beam 2 in the previous process, facilitating the splicing of the second truss 1 segment, repeating the operation until the cross beam 2 moves to the channel bottom under the action of the walking wheel 601 and completes the splicing of all truss 1 segments, compared with the prior art, the influence of the complex underwater environment (water flow, poor visibility, and side slope length) on the splicing of the truss 1 is reduced, thereby improving the efficiency of the splicing of the truss 1.

[0038] Furthermore, by adjusting the mechanism, when the cross beam 2 is erected on the channel surface, the support seat 6 can be extended by the adjusting mechanism to increase the distance between the walking wheel 601 and the cross beam 2, so that a height difference is formed between the walking wheel 601 and the moving mechanism at the bottom of the cross beam 2, so that the walking wheel 601 is not interfered by the moving mechanism when walking on the channel surface, and at the same time, when the walking wheel 601 moves to the channel bottom, the support seat 6 can be retracted by the adjusting mechanism to reduce the distance between the walking wheel 601 and the cross beam 2, so that the moving mechanism is erected on the channel bottom, realizing the conversion of the driving direction of the cross beam 2.

[0039] Based on the above scheme, the structure of the adjusting mechanism is optimized, as shown in Figure 5 The adjusting mechanism comprises:

[0040] The mounting seat 4 is arranged on the side surface of the cross beam 2.

[0041] The first transmission member 401 is arranged on the mounting seat 4 and is in transmission connection with the support seat 6.

[0042] The mounting seat 4 is arranged on the side of the cross beam 2 to provide fixation and support for the first transmission member 401, which can be a telescopic structure such as a pneumatic cylinder. The mounting end of the pneumatic cylinder is fixed to the mounting seat 4, and the telescopic end penetrates through the mounting seat 4 and is connected to the support seat 6. The spacing between the support seat 6 and the cross beam 2 is adjusted by controlling the telescopic movement of the telescopic end, so as to adjust the height difference between the walking wheel 601 and the moving mechanism. Preferably, the first transmission member 401 is a worm gear elevator. The worm gear is driven to rotate by a pneumatic or electric drive, so as to drive the screw rod to move up and down, thereby adjusting the height difference between the walking wheel 601 and the moving mechanism. The device has the characteristics of compact structure, small size, light weight, wide power source, no noise, easy installation, and flexible use.

[0043] Meanwhile, the mounting seat 4 is provided with a limiting block 403, and the support seat 6 is provided with a connecting guide rail 402 in the height direction. The connecting guide rail 402 is slidingly connected to the limiting block 403. By slidingly connecting the connecting guide rail 402 to the limiting block 403, the support seat 6 can be accurately guided during lifting or moving, so as to ensure stable movement trajectory and prevent deviation. Meanwhile, the support seat 6 can be radially supported, so as to effectively prevent the support seat 6 from derailing or tilting during lifting or moving. When bearing the load transmitted from the support seat 6 and the truss 1, the device can effectively disperse the stress, prevent structural loosening or instability caused by unbalanced load or vibration, and improve the overall structural strength and operation stability of the device.

[0044] Based on the above scheme, the structure of the moving mechanism is optimized, as shown in Figure 3 and Figure 4 The moving mechanism comprises:

[0045] The track 3 is arranged at the bottom of the cross beam 2.

[0046] The drive 302 is arranged on the cross beam 2, and the drive 302 is in transmission connection with the track 3 through the chain 301.

[0047] Compared with the traditional tire type moving mechanism, the caterpillar 3 can provide a larger contact area under the action of the caterpillar 3, which makes the equipment have better passability on soft, uneven or slippery ground, especially in the complex and variable environment such as the bottom of the river or the water channel, and the friction between the caterpillar 3 and the ground is larger, so the traction of the equipment can be significantly improved, and the weight of the equipment can be more evenly distributed on a larger contact area, thereby reducing the pressure concentration on the ground, wherein the caterpillar 3 adopts an engineering rubber caterpillar, which can avoid damaging the channel bottom compared with a metal caterpillar, and can absorb part of the vibration to provide a more stable driving experience; and the driver 302 is directly connected with the caterpillar 3 in transmission through the chain 301, which ensures the effective transmission of power and reduces energy loss, and the driver 302 adopts a motor which can be used in cooperation with a transmission.

[0048] As shown in Figure 1 , the present application also provides a truss support system, which comprises a truss 1 and a walking unit arranged at the water outlet end of the truss 1, and further comprises the walking type underwater support equipment described above, and the specific structure of the walking type underwater support equipment is referred to the above embodiments. The walking unit adopts the form of a gantry, and a transmission structure similar to the caterpillar 3 is installed at the bottom of the gantry and is synchronously controlled with the cross beam 2, so that the truss 1 can move in the channel or the river, and a wider coverage range can be achieved in a large water channel or river, and effective repair work on the lining plate in different positions can be ensured.

[0049] Specifically, as shown in Figure 2 and Figure 6 , the water inlet end of the truss 1 is provided with a first connecting seat 102, the top of the cross beam 2 is provided with a connecting beam 101, the connecting beam 101 is provided with a second connecting seat 501, and the second connecting seat 501 is rotationally connected with the first connecting seat 102. Due to the existence of the rotational connection, the support equipment can be deflected or inclined within a certain angle range relative to the truss 1, so as to better adapt to the complex working conditions such as the undulating topography and slope change of the channel bottom, so that the support equipment can have a certain posture adjusting capability during movement or operation with the truss 1, and at the same time, the rotational connection structure can provide a certain tolerance space during the initial installation stage, so that the equipment is more easily connected and positioned with the truss 1, and the on-site assembly efficiency is improved.

[0050] Specifically, as shown in Figure 6As shown, the connecting beam 101 is provided with a second transmission member 502, and the second connecting seat 501 is provided with a mounting plate 5 which is in transmission connection with the second transmission member 502. The second transmission member 502 is arranged on the connecting beam 101 and serves as a power transmission component for the mounting plate 5. The second transmission member 502 can be in the form of a cylinder, a screw nut mechanism, etc., and is preferably in the form of a worm gear elevator. The worm gear elevator is driven to rotate by a pneumatic or electric manner, so as to drive the screw rod to move up and down, thereby realizing the up and down adjustment of the mounting plate 5. During the initial butt joint process between the truss 1 and the equipment, the position of the mounting plate 5 can be finely adjusted by the second transmission member 502, so that the second connecting seat 501 is accurately aligned with the first connecting seat 102 of the truss 1, thereby greatly reducing the manual intervention and improving the assembly efficiency and reliability.

[0051] Moreover, the connecting beam 101 is provided with a sliding rail 503, and the mounting plate 5 is provided with a sliding block 504 which is slidingly connected to the sliding rail 503. The mounting plate 5 can slide along a specific direction on the sliding rail 503 under the cooperation of the sliding rail 503 and the sliding block 504, so as to realize the position fine adjustment and movement guidance of the second connecting seat 501 and the equipment connected thereto. The sliding rail 503 and the sliding block 504 can be in the form of a T-shaped slot, a dovetail slot or a rectangular guide rail, etc., and have good guiding property and bearing capacity.

[0052] Specifically, as shown in the figure, Figure 6 The bottom of the connecting beam 101 is provided with a connecting plate 7 which is provided with a plurality of bolts 701 which are in threaded connection with the cross beam 2. The connecting beam 101 and the cross beam 2 are firmly combined together by the bolt 701 connection mode. This non-permanent connection mode such as welding makes the disassembly and assembly of the equipment more convenient and fast, and is beneficial to the daily inspection, maintenance and replacement of parts.

[0053] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
