DETAILED DESCRIPTION

[0022] like Figure 1-4 As shown, the present invention provides a submerged trench transportation device for an urban pipe gallery, comprising a central frame 1, mounting seats 201 installed at both ends of the central frame 1, a first-stage lifting assembly vertically connected to the mounting seats 201, a second-stage lifting assembly slidably connected to the bottom end of the first-stage lifting assembly, a retractable supporting device connected to the bottom of the second-stage lifting assembly, a clamping mechanism installed between the two mounting seats 201 for clamping the pipe gallery, and a locking mechanism vertically slidably connected to the end of the clamping mechanism for locking the pipe gallery, and a roller 404 is rotatably arranged at the bottom of the second-stage lifting assembly.

[0023] The center frame 1 is a rectangular metal frame structure. Both ends of the center frame 1 are installed with mounting seats 201. The mounting seats 201 are vertically installed at the ends of the center frame 1. The first-stage lifting assembly is installed on the mounting seats 201, and the second-stage lifting assembly is installed on the first-stage lifting assembly. The lifting range of the center frame 1 can be greatly improved by the first-stage lifting assembly and the second-stage lifting assembly. The support device is installed at the bottom of the second-stage lifting assembly to assist in supporting the second-stage lifting assembly to improve the stability of the transport device. The roller 404 is installed at the bottom of the second-stage lifting assembly to support the movement of the transport device.

[0024] After the first-stage lifting assembly and the second-stage lifting assembly are both retracted, the height of the center frame 1 is lowered, and the center frame 1 drives the clamping mechanism and the locking mechanism between the two mounting seats 201 to move downward. After the clamping mechanism and the locking mechanism clamp and lock the pipe gallery, the first-stage lifting assembly and the second-stage lifting assembly can be adjusted to lift the pipe gallery, and then the pipe gallery can be transported.

[0025] like Figure 1As shown, the lifting and lowering adjustment of a section lifting component is realized. The section lifting component comprises a screw rod 301, a driving motor 302, a guide rail 303 and a slider 304. The central frame 1 is provided with a threaded hole 305 threadedly connected to the screw rod 301. The guide rail 303 is fixed to the central frame 1. The side wall of the slider 304 is provided with a slide groove 306 slidably matched with the guide rail 303 and vertically slidably connected to the guide rail 303. The driving motor 302 is installed at the bottom of the section lifting component and is coaxially rotatably connected to the screw rod 301 through a machine hole 307.

[0026] A threaded hole 305 is provided on the mounting seat 201, and the screw rod 301 is connected through the threaded hole 305. The screw rod 301 is driven to rotate by the driving motor 302. Since the guide rail 303 and the slider 304 slide together through the slide groove 306, the rotation of the screw rod 301 will cause the mounting seat 201 to move along the axial direction of the screw rod 301, thereby realizing the position adjustment of the mounting seat 201 in the vertical direction, that is, adjusting the height of the center frame 1.

[0027] like Figure 1 The two-stage lifting assembly includes a slide rail 401, a base 402 and a pad 403. The slide rail 401 is vertically fixed to the outer side wall of the one-stage lifting assembly. The side wall of the base 402 is provided with a guide groove 406 that slidably cooperates with the slide rail 401. A first electric push rod 405 is hinged between the top outer side of the base 402 and the top of the slide rail 401.

[0028] The top end of the first electric push rod 405 is rotatably connected to the ear plate set on the top of the slide rail 401 through the reamer hole 407. By controlling the first electric push rod 405 to extend, the slide rail 401 can be pushed to move vertically upward along the guide groove 406, thereby realizing the raising of a section of the lifting component. Conversely, by controlling the first electric push rod 405 to retract, the lowering of a section of the lifting component can be realized.

[0029] like Figure 2 As shown. The bottom of the base 402 is provided with a pad 403, and the rollers 404 are rotatably connected to the bottom of the pad 403, and the rollers 404 are arranged side by side. By providing the rollers 404 and the pad 403 to roll and support the base 402, the movement of the transport device is easier.

[0030] like Figure 1 , Figure 2 and Figure 4A connection groove is provided at one side of the bottom of the base 402, a capstan seat 202 is vertically fixedly arranged in the connection groove, the support assembly is rotatably connected to the capstan seat 202, the support assembly comprises a support rod 601, a top rod 602 and a third electric push rod 603, one end of the support rod 601 is rotatably connected to the capstan seat 202, the other end of the support rod 601 is provided with a long groove 604, the top rod 602 is slidably connected in the long groove 604, and the two ends of the third electric push rod 603 are respectively connected between the support rod 601 and the top rod 602.

[0031] When the transport device needs to be fixed in position, the third electric push rod 603 is controlled to extend, and the output end of the third electric push rod 603 pushes the top rod 602 to move toward the outside of the support rod 601. Then, the foot at the bottom end of the top rod 602 is rotated to lower the height of the foot and fit it to the ground, and the top rod 602 provides auxiliary support. Moreover, the foot fits the ground and can better provide friction to prevent the transport device from sliding under the support of the roller 404.

[0032] like Figure 4 As shown, in order to improve the stability of the movement of the push rod 602, a limit block 702 is fixedly provided on the outer side wall of the support rod 601, a limit rod 701 is horizontally fixedly provided on the outer side wall of the push rod 602, and a limit hole 703 is provided on the limit block 702 for the limit rod 701 to pass through. The limit rod 701 cooperates with the limit hole 703 on the limit block 702 to guide the axial movement of the limit rod 701, so as to ensure that the push rod 602 moves stably when pushed by the third electric push rod 603.

[0033] like Figure 1 and Figure 3 The clamping mechanism comprises a second electric push rod 501, a joint 502, a support arm 503, a top pull rod 504, a bottom pull rod 505 and a connecting rod 506. The second electric push rod 501 is vertically connected to the top of the center frame 1. The joint 502 is fixedly connected to the movable end at the top of the second electric push rod 501. The top end of the support arm 503 is rotatably connected to the joint 502. The top pull rod 504 and the bottom pull rod 505 are both rectangular frame structures, and the top ends of the top pull rod 504 and the bottom pull rod 505 are rotatably connected to the top and bottom of the mounting seat 201, respectively. A connecting rod 506 is connected between the top pull rod 504 and the bottom pull rod 505. A through hole 507 is provided at the bottom end of the support arm 503 for the top pull rod 504 to pass through.

[0034] The second electric push rod 501 is extended, and the support arm 503 is pulled upward through the connection hole 508 for rotational connection between the joint 502 and the support arm 503. The support arm 503 pulls the top pull rod 504 to rotate around the hinge axis between the top pull rod 504 and the mounting seat 201. The top pull rod 504 then drives the bottom pull rod 505 to rotate through the connecting rod 506, so that the top pull rod 504 and the bottom pull rod 505 rotate upward. The second electric push rods 501 on both sides of the center frame 1 act synchronously, so that the clamping mechanisms on both sides of the center frame 1 rotate upward at the same time, clamping the pipe gallery between the two clamping mechanisms and pushing it upward, so as to achieve clamping and preliminary lifting of the pipe gallery; the lower method of the pipe gallery is opposite to the above clamping and lifting direction. The top pull rod 504 and the bottom pull rod 505 contact the top side and the bottom side of the pipe gallery respectively, and the two top pull rods 504 and the two bottom pull rods 505 can achieve stable clamping and lifting of the pipe gallery.

[0035] like Figure 2 As shown. The locking mechanism is installed on the connecting rod 506, and the locking mechanism includes an auxiliary block 801 and a screw 802. A groove 803 is vertically opened on the connecting rod 506, and the auxiliary block 801 is slidably set in the groove 803. The inner side of the auxiliary block 801 is provided with an arc groove adapted to the outer wall of the pipe gallery. The end wall of the connecting rod 506 is provided with a screw hole 804 connected to the groove 803, and the screw 802 is connected to the screw hole 804. After the clamping mechanism completes the clamping and preliminary lifting of the pipe gallery, the auxiliary block 801 is slid toward the direction of the pipe gallery so that the arc groove of the auxiliary block 801 cooperates with the outer wall of the pipe gallery, and then the auxiliary block 801 is supported by the connecting rod 506, so that the auxiliary block 801 will not slide outward, ensuring that the auxiliary block 801 stably clamps the pipe gallery and ensures the stability of the pipe gallery transportation.

[0036] like Figure 1 As shown, in order to improve the tightness of the auxiliary block 801 and the pipe gallery and improve the stability of the auxiliary block 801 clamping the pipe gallery, a rubber pad 901 is fixedly arranged in the arc groove.

[0037] A method for using a submerged trough transport device for an urban pipe gallery comprises the following steps: Step 1: Move, by supporting the roller 404, push or pull the transport device to move above the pipe gallery; Step 2: Clamping: Control the first lifting assembly to retract, drive the center frame 1 to descend, control the second lifting assembly to retract, drive the first lifting assembly and the center frame 1 to descend, so that the clamping mechanism connected to the center frame 1 moves downward, so that the pipe gallery is located directly below the clamping mechanism, and the pipe gallery is clamped by the clamping mechanism; Step 3: Locking: adjusting the locking mechanism on the clamping mechanism to further clamp the clamped pipe gallery through the locking mechanism; Step 4: Support, control the support device on the second-stage lifting assembly to extend so that the bottom of the support device contacts the ground to provide stable support for the transport device; Step 5: Lifting: Control the first lifting assembly to lift the central frame 1, and the central frame 1 lifts the pipe gallery through the clamping mechanism. After the pipe gallery is lifted, control the second lifting assembly to extend, and further lift the central frame 1 and the pipe gallery. Step 6: Transport: Push or pull the transport device to move the pipe gallery to the set position, then control the first and second lifting assemblies to lower the pipe gallery, and then release the locking mechanism and the clamping mechanism to complete the transport of the pipe gallery.
