DETAILED DESCRIPTION

[0043] The present invention provides a mobile underground structure side wall formwork system to replace the traditional underground side wall support structure, thereby avoiding the problem of frequent disassembly and assembly of a large number of support frames during use, thereby wasting time and increasing the workload of workers.

[0044] Figure 1-Figure 8 The structure diagram of a movable underground structure side wall formwork system of the present invention is shown in FIG. Figure 1-Figure 8 A detailed introduction is given to this type of mobile underground structure side wall formwork system.

[0045] Example 1

[0046] refer to Figure 1-Figure 7 The present invention discloses a mobile underground structure side wall formwork system, the main part of which includes a mobile base 100, a telescopic support mechanism 200, an embedded mechanism 300 and a driving mechanism 400.

[0047] refer to Figure 1-Figure 5 , the mobile base 100 is used to provide a stable moving track for the movement of the telescopic support mechanism 200;

[0048] In this embodiment, reference Figure 3 and Figure 5 The mobile base 100 includes two cross beams 110 with a first slide groove 110a on the top, a first longitudinal beam 120 located between the two cross beams 110, and a moving wheel 130 located at the bottom of the two cross beams 110. The two cross beams 110 and the first longitudinal beam 120 form an integral base. The first slide groove 110a is used to cooperate with the slider 210a-1 to provide a stable track for the movement of the installation frame 210a. The moving wheel 130 is used to facilitate the movement of the mobile base 100;

[0049] In this embodiment, reference Figure 5 The side wall of the cross beam 110 is provided with a connecting plate 110b, which is used to facilitate connection with the spring 220b-2, so as to stretch the spring 220b-2 when the mobile base 100 moves. The bottom of the first longitudinal beam 120 is evenly provided with a plurality of arc-shaped claws 120a, which are used to increase the friction between the mobile base 100 and the ground when the telescopic support mechanism 200 is in the first state after the contraction of the telescopic support mechanism 200, so that the grip is more firm, thereby preventing the mobile base 100 from rebounding when the driving mechanism 400 drives the telescopic support mechanism 200 to expand, causing the telescopic support mechanism 200 to be unable to move.

[0050] refer to Figure 1-Figure 4 and Figure 6-Figure 7 The telescopic support mechanism 200 is used to support the underground side wall after construction. The telescopic support mechanism 200 is slidably connected to the top of the mobile base 100 to facilitate the movement of the telescopic support mechanism 200. The telescopic support mechanism 200 includes a base member 210 slidably connected to the top of the mobile base 100, a connecting member 220 located on the side wall of the base member 210, a supporting member 230 movably connected to the connecting member 220, and a supporting plate 240 located on the side of the supporting member 230. The supporting plate 240 is used to support the underground side wall;

[0051] The telescopic support mechanism 200 has a first state when it is retracted and a second state when it is extended. In the first state, the telescopic support mechanism 200 is retracted, which is convenient for storing the entire device. In the second state, the underground side wall is supported without disassembly and assembly, thereby reducing the workload.

[0052] In this embodiment, reference Figure 6 The base member 210 includes a mounting frame 210a having a slider 210a-1 at the bottom and a second longitudinal beam 210b located inside the mounting frame 210a. The mounting frame 210a and the second longitudinal beam 210b form an integral structure. The slider 210a-1 is slidably connected to the first slide groove 110a to facilitate the mounting frame 210a to slide stably along the first slide groove 110a when moving.

[0053] refer to Figure 4-Figure 6 The connecting member 220 is located on the side wall of the installation frame 210a. A rotating rod 220a is provided on the inner side of the connecting member 220 for connecting with the sleeve block 230a-1 and the supporting member 230, thereby driving the rotating rod 220a to rotate when the supporting member 230 rotates;

[0054] refer to Figure 7 The support member 230 includes a connection frame 230a having a sleeve block 230a-1 at the bottom, which is used to connect with the connection member 220 and is convenient for connecting with the support plate 240. The sleeve block 230a-1 is connected to the rotating rod 220a and is used to drive the rotating rod 220a to rotate when the support member 230 rotates;

[0055] In this embodiment, reference Figure 6 , mounting blocks 210a-2 with first limiting sliding grooves 210a-21 on the surface are provided on both sides of the mounting frame 210a, for facilitating the movable installation of embedded parts;

[0056] In this embodiment, reference Figure 7 The surface of the second longitudinal beam 210b is provided with a second slide groove 210b-1, and the inner side of the connecting frame 230a is provided with a third longitudinal beam 230a-2 with a third slide groove 230a-21 on the surface, which is used to facilitate the driving cylinder 410 to drive the hinge rod 420 to rotate when working, thereby driving the connecting frame 230a to rotate, and the second slide groove 210b-1 and the third slide groove 230a-21 are slidably connected with an articulated seat, which is used to facilitate the articulation with the articulated rod 420;

[0057] In this embodiment, reference Figure 4 The side wall of the connecting member 220 is provided with a convex plate 220b, and the side wall of the convex plate 220b is provided with a second limiting sliding groove 220b-1 penetrating the convex plate 220b for movably connecting the push rod 430b, refer to Figure 1-Figure 4A spring 220b-2 is provided on one side of the protruding plate 220b adjacent to the connecting plate 110b, with one end connected to the side wall of the protruding plate 220b and the other end connected to the side wall of the connecting plate 110b. The spring 220b-2 is used to stretch the spring 220b-2 when the driving mechanism 400 drives the telescopic support mechanism 200 to contract and the movable base 100 moves. When the driving mechanism 400 drives the telescopic support mechanism 200 to expand, the restoring force generated by the stretched spring 220b-2 pulls the entire telescopic support mechanism 200 to move along the first sliding groove 110a.

[0058] refer to Figure 1-Figure 4 The embedded mechanism 300 is used to be inserted into the ground to fix the telescopic support mechanism 200 when the telescopic support mechanism 200 is unfolded, and the embedded mechanism 300 is movably installed on both sides of the base member 210;

[0059] In this embodiment, reference Figure 1-Figure 3 The embedded mechanism 300 includes a lifting column 310 located in the first limiting slide groove 210a-21 and an insertion column 320 located at the bottom of the lifting column 310. When the lifting column 310 descends, it drives the insertion column 320 to descend and insert into the soil, thereby fixing the entire telescopic support mechanism 200. When the lifting column 310 rises, it drives the insertion column 320 to rise and be pulled out of the soil, thereby facilitating the movement of the telescopic support mechanism 200.

[0060] In this embodiment, reference Figure 3 A second thread groove 310a is provided on the surface of the lifting column 310 for facilitating cooperation with the second screw rod 440b-1. When the second screw rod 440b-1 rotates, the lifting column 310 is driven to move up and down under the limiting action of the first limiting slide groove 210a-21.

[0061] refer to Figure 1-Figure 4 The driving mechanism 400 is used to drive the telescopic support mechanism 200 to retract or expand when working. The driving mechanism 400 is installed on the telescopic support mechanism 200. When working, the driving mechanism 400 drives the telescopic support mechanism 200 to switch between the first state and the second state and synchronously drives the mobile base 100 and the telescopic support mechanism 200 to move alternately. Then, when it is necessary to support the underground side wall built in front, the driving mechanism 400 first retracts the telescopic support assembly while driving the mobile base 100 to move, and then drives the telescopic support mechanism 200 to expand and move while driving the telescopic support mechanism 200 to move through the driving mechanism 400;

[0062] In this embodiment, reference Figure 2The driving mechanism 400 includes a driving cylinder 410 hinged on the inner wall of the installation frame 210a, a hinged rod 420 hinged at one end to the output section of the driving cylinder 410 and hinged at the other end to the hinge seat in the third slide groove 230a-21, a first driving component 430 transmission-connected to the mobile base 100, and a second driving component 440 transmission-connected to the embedded mechanism 300. When the driving cylinder 410 is working, it drives the hinged rod 420 to slide and flip, so that the connecting frame 230a flips with the rotating rod 220a as the axis. When the telescopic support mechanism 200 is in the first state of contraction, the first driving component 430 drives the embedded mechanism 300 to rise, and the second driving component 440 drives the mobile base 100 to move. When the telescopic support mechanism 200 is in the second state of expansion, the first driving component 430 drives the embedded mechanism 300 to descend, and the second driving component 440 cooperates with the spring 220b-2 to drive the telescopic support mechanism 200 to move;

[0063] In this embodiment, reference Figure 4 The first driving assembly 430 includes a first gear 430a located on the side wall of the rotating rod 220a, a push rod 430b movably connected in the second limiting sliding groove 220b-1 and having a first threaded groove 430b-1 on the side wall, and a first screw rod 430c located in the first threaded groove 430b-1 and having a second gear 430c-1 on the side wall. When the driving cylinder 410 is working, the connecting frame 230a is driven to rotate. At this time, the rotating rod 220a rotates to drive the first gear 430a to rotate, and the first gear 430a is meshed with the second gear 430c-1. The first gear 430a rotates to drive the second gear 430c-1 to rotate, and the second gear 430c-1 rotates to drive the first screw rod 430c to rotate. When the first screw rod 430c rotates, the push rod 430b moves under the limiting action of the second limiting sliding groove 220b-1, thereby pushing the side wall of the connecting rod, and then pushing the movable base 100;

[0064] In this embodiment, reference Figure 2The second driving assembly 440 includes a first bevel gear set 440a located on the side of the rotating rod 220a away from the first gear 430a, two second bevel gear sets 440b which are transmission-connected to the first bevel gear set 440a and have a second screw rod 440b-1 at the bottom, and a transmission rod 440c located between the two second bevel gear sets 440b. The second screw rod 440b-1 is threadedly connected to the second thread groove 310a. When the rotating rod 220a rotates, it drives the first bevel gear set 440a to rotate, and then drives the two second bevel gear sets 440b to rotate under the connection action of the transmission rod 440c. The rotation of the second bevel gear set 440b drives the second screw rod 440b-1 to rotate. When the second screw rod 440b-1 rotates, the lifting column 310 performs a lifting movement under the limiting action of the first limiting slide groove 210a-21, thereby driving the plug column 320 to perform a lifting movement.

[0065] In this embodiment, the specific use process is as follows: when it is necessary to support the underground side wall in front, refer to Figure 2 , the connecting frame 230a is turned and retracted by driving the cylinder 410, and at the same time, the first screw rod 430c in the first driving assembly 430 rotates and drives the push rod 430b to push the mobile base 100 to move. At this time, the second driving assembly 440 drives the embedded mechanism 300 to slowly rise, and at the same time, the telescopic support mechanism 200 is fixed by the embedded mechanism 300, thereby ensuring that the telescopic support mechanism 200 does not move, and the mobile base 100 moves forward. Figure 1 Then, the connecting frame 230a is driven to expand by driving the cylinder 410, and at the same time, the first screw rod 430c in the first driving assembly 430 is reversed. At this time, the mobile base 100 grasps the ground under the action of the arc claw 120a, and at the same time, the tensile force of the spring 220b-2 makes the mobile base 100 immobile, while the telescopic support mechanism 200 moves forward, thereby completing the repeated contraction and expansion of the telescopic support mechanism 200 while making the mobile base 100 and the telescopic support mechanism 200 move forward alternately, without the need to disassemble the entirety.

[0066] Example 2

[0067] On the basis of Example 1, in order to facilitate the adjustment of the support height of the support plate 240, refer to Figure 1-Figure 8 , movable grooves 230a-3 are provided on both sides of the top of the connecting frame 230a for facilitating the movable installation of the adjusting member 230b, refer to Figure 8 The inner wall of the connecting frame 230a is provided with a mounting groove 230a-4 which is connected with the movable groove 230a-3 and has a damping bearing 230a-41 on the inner wall, so as to facilitate the installation of the gear plate 230c-1;

[0068] refer to Figure 7The support member 230 further includes an adjusting member 230b movably mounted in the movable groove 230a-3 and a driving member 230c located on the side wall of the connecting frame 230a and driving the adjusting member 230b to move up and down along the movable groove 230a-3 during operation, thereby adjusting the height of the adjusting member 230b through the driving member 230c;

[0069] refer to Figure 7 The adjusting member 230b includes an adjusting frame 230b-1 connected to the side wall of the supporting plate 240, a sawtooth plate 230b-2 located at the bottom of the adjusting frame 230b-1 and located in one of the movable grooves 230a-3, and a movable plate 230b-3 located at the bottom of the adjusting frame 230b-1 and located in the other movable groove 230a-3. When the height of the adjusting member 230b is adjusted, it is convenient to adjust the height of the supporting plate 240;

[0070] refer to Figure 7 The driving member 230c includes a gear plate 230c-1 connected to the damping bearing 230a-41 and meshing with the serrated plate 230b-2, and a knob 230c-2 located on the side wall of the gear plate 230c-1. The gear plate 230c-1 is driven to rotate by rotating the knob 230c-2. When the gear plate 230c-1 rotates, the serrated plate 230b-2 is driven to rise and fall, thereby driving the entire adjusting member 230b to rise and fall, and thereby driving the support plate 240 to rise and fall, wherein the gear plate 230c-1 is connected to the damping bearing 230a-41 on the inner wall of the mounting groove 230a-4, and the damping bearing 230a-41 is used to lock the knob 230c-2, thereby preventing the adjusting frame 230b-1 from automatically descending under its own gravity.

[0071] In this embodiment, the specific usage process is as follows: the adjustment member 230b is driven to rise and fall by rotating the knob 230c-2, and the support plate 240 is driven to rise and fall by the rising and falling of the adjustment member 230b, thereby adjusting the height of the support plate 240.

[0072] Example 3

[0073] On the basis of Example 2, the load-bearing burden of the driving cylinder 410 is reduced, referring to Figure 1 , further comprising a rotating member 500, the rotating member 500 comprising a first rotating plate 510 hinged at one end to a hinge seat in the third slide groove 230a-21 and having a plurality of elastic sheets uniformly arranged on the side wall along the circumferential direction, a second rotating plate 520 hinged at one end to a hinge seat in the second slide groove 210b-1 and having a plurality of elastic sheets uniformly arranged on the side wall along the circumferential direction, and a rotating column 530 whose two sides are respectively rotatably connected to the first rotating plate 510 and the second rotating plate 520 and having a plurality of elastic sheets uniformly arranged on the surface and the side wall along the circumferential direction;

[0074] Among them, the elastic sheets on the first rotating plate 510 and the second rotating plate 520 are respectively interlaced with the elastic sheets on the rotating column 530. When the driving cylinder 410 is working, the driving connecting frame 230a is flipped, and the first rotating plate 510 and the second rotating plate 520 slide and rotate at the same time. At this time, the elastic sheets on the first rotating rod and the second rotating rod are squeezed with the elastic sheets on the rotating column 530 to complete repeated interlaced engagement, and then support the base member 210 and the support member 230 when the driving mechanism 400 is not working, thereby reducing the pressure of the support member 230 and the support plate 240 on the driving cylinder 410 under their own gravity.
