DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] The present invention discloses a full-chamber bracket mold transfer device in a narrow space, such as Figure 1-12As shown, it includes a plurality of mold shifting units evenly installed on two opposite sides of the full-hall bracket 100. Each mold shifting unit includes a supporting passive walking mechanism, a stepping top supporting mechanism, a gripping mechanism 500 and an angle adjustment mechanism 900. Among them, the supporting passive walking mechanism is supported on the bottom of the full-hall bracket 100, the supporting passive walking mechanism is connected to the stepping top supporting mechanism, and the gripping mechanism 500 is hinged at one end of the stepping top supporting mechanism away from the supporting passive walking mechanism, the angle adjustment mechanism 900 is movably connected to the stepping top supporting mechanism, and the end of the angle adjustment mechanism 900 away from the stepping top supporting mechanism is detachably connected to the bottom of the full-hall bracket 100, and the setting form of the angle adjustment mechanism 900 can be adjusted according to the situation; when the angle adjustment mechanism 900 is in a horizontal form and connected to the full-hall bracket 100, the stepping top supporting mechanism and The angle of the supporting passive walking mechanism is adjusted synchronously; when the angle adjustment mechanism 900 is in a vertical form and connected to the full-chamber bracket 100, its function is to suspend the stepping top support mechanism, so that when the stepping top support mechanism is performing the propulsion operation, the output end of the stepping top support mechanism remains horizontal or tilted upward. When the output end of the stepping top support mechanism is in a tilted upward state, the stepping top support mechanism provides a vertical lifting force while providing a thrust in the horizontal direction, thereby reducing the friction between the supporting passive walking mechanism and the guide rail or the ground, so that the full-chamber bracket 100 can be pushed more smoothly. The working principle and advantage of the present invention are: after the construction of the target segment is completed, the present invention removes the upper connecting piece of the full-chamber bracket 100, and on the basis of the full-chamber bracket 100, it can be selected whether to install the guide rail on the ground at the bottom of the full-chamber bracket 100 according to the flatness of the ground, that is, the guide rail can be installed on the ground when the ground is flat, and when the ground is uneven, the guide rail can be not installed. Afterwards, multiple mold shifting units are evenly installed on two opposite sides of the full-hall bracket 100, and then each stepping support mechanism is adjusted to a support form, that is, one end of the stepping support mechanism is in contact with the ground, and the other end of the stepping support mechanism is connected to the lower part of the full-hall bracket 100. At this time, the stepping support mechanism is in a vertical state; then, the stepping support mechanism is controlled to perform a vertical lifting action to lift up the full-hall bracket 100, and then the fixing parts at the bottom of the full-hall bracket 100 are removed. At this time, the stepping support mechanism is controlled to perform a vertical return action until the supporting passive walking mechanism is supported on the ground or the guide rail.Then, adjust the stepping top support mechanism to a propulsion form, so that the stepping top support mechanism is consistent with the propulsion direction, and make the end of the stepping top support mechanism away from the supporting passive walking mechanism in a free state. When performing the propulsion operation, the gripping mechanism 500 connected to this end of the stepping top support mechanism grips the ground or the guide rail, and the stepping top support mechanism extends and drives the full-hall bracket 100 to move along the guide rail or the predetermined direction; when the stepping top support mechanism completes a stroke, the stepping top support mechanism gradually contracts, and during the contraction process, the gripping mechanism 500 is disengaged from the ground or the guide rail, so that the free end of the stepping top support mechanism (the end connected to the gripping mechanism 500) retracts to facilitate the next propulsion operation. When it is necessary to move the full-hall bracket 100 obliquely or laterally, the angle adjustment mechanism 900 is controlled to move, so that the step-by-step support mechanism rotates a certain angle, so that the step-by-step support mechanism drives the supporting passive walking mechanism to rotate a corresponding angle, and then the oblique or transverse advancement operation is performed; the present invention advances the full-hall bracket 100 longitudinally, laterally and obliquely, so that the full-hall bracket 100 moves smoothly and steadily to the next working surface (construction section). In summary, the present invention can move the full-hall bracket 100 as a whole, replacing the complicated operations in the existing disassembly and assembly, improving the construction efficiency, and achieving the purpose of reducing the intensity of the operation.

[0020] As a preferred embodiment of the present invention, Figure 2 , 4As shown in Figures 1 and 12, the supported passive walking mechanism includes a vertical connecting column 600, a walking assembly 300 and a connecting assembly 200. Among them, the upper end of the walking assembly 300 is fixedly connected to the lower end of the vertical connecting column 600, and the lower end of the connecting assembly 200 is rotatably connected to the upper end of the vertical connecting column 600. The walking assembly 300 of this embodiment walks on a guide rail or the ground, the connecting assembly 200 is detachably connected to the lower end of the full-chair bracket 100, and the corresponding end of the stepping top support mechanism is connected to the vertical connecting column 600. When the step-up support mechanism of this embodiment is performing the pushing operation, it pushes the vertical connection column 600 to move in a predetermined direction, so that the full-chair support 100 connected to the connection component 200 moves with the walking component 300, thereby achieving the purpose of moving the full-chair support 100; when the full-chair support 100 needs to be moved obliquely or horizontally, the angle adjustment mechanism 900 is controlled to operate, so that it drives the step-up support mechanism to rotate a predetermined angle with the vertical connection column 600 as the axis, and drives the vertical connection column 600 to rotate, and the vertical connection column 600 synchronously drives the walking component 300 to rotate a corresponding angle during the rotation process. The walking component 300 of this embodiment includes a first connection seat 301 and two assembly wheel seats 302, wherein the center position of the upper end surface of the first connection seat 301 is fixedly connected to the vertical connection column 600, and the two assembly wheel seats 302 are arranged side by side below the first connection seat 301, and a first channel 307 is formed between the two assembly wheel seats 302. In order to facilitate crossing obstacles or passing through uneven areas, the present embodiment adopts the following measures: transition guide edges 304 are respectively constructed at both ends of the length direction of each assembly wheel seat 302, and each transition guide edge 304 extends obliquely upward. In the present embodiment, a plurality of running wheels 303 are rotatably connected to each assembly wheel seat 302, and these running wheels 303 are arranged at intervals along the length direction of the assembly wheel seat 302. A plurality of vertical screws 305 are constructed at the upper end of the assembly wheel seat 302, and these vertical screws 305 are arranged at intervals along the length direction of the assembly wheel seat 302. One end of each vertical screw 305 passes through the first connection seat 301, and two locking nuts 306 are threadedly connected to each vertical screw 305, and these two locking nuts 306 are locked on the end faces of both ends of the first connection seat 301. In this embodiment, the distance between the two assembly wheel seats 302 and the first connection seat 301 can be adjusted by adjusting the vertical connection position of the vertical screw rod 305 and the first connection seat 301, thereby avoiding the first connection seat 301 from scratching the ground.The connection assembly 200 of this embodiment includes a second connection seat 201 and a plurality of first hydraulic expansion sleeves 203, wherein the center position of the lower end surface of the second connection seat 201 is rotatably connected to the vertical connection column 600, and a plurality of strip connection holes 202 are evenly opened on the second connection seat 201 along its circumference, and each strip connection hole 202 extends along the radial direction of the vertical connection column 600. The above-mentioned plurality of first hydraulic expansion sleeves 203 are assembled on the second connection seat 201, and each first hydraulic expansion sleeve 203 is movably connected to the second connection seat 201 through the corresponding strip connection hole 202, and the first hydraulic expansion sleeve 203 tightens the lower end of the vertical rod corresponding to the lower part of the full-chamber bracket 100. In this embodiment, the position of the first hydraulic expansion sleeve 203 in the strip connecting hole 202 is adjusted so that the first hydraulic expansion sleeve 203 corresponds to the lower part of the corresponding vertical rod in the full-height bracket 100, and the lower part of the vertical rod is inserted into the first hydraulic expansion sleeve 203. The first hydraulic expansion sleeve 203 is driven by hydraulic oil to tighten the vertical rod, thereby achieving the purpose of connecting and fixing the connecting assembly 200 to the lower part of the full-height bracket 100.

[0021] As a preferred embodiment of the present invention, Figure 2 , 5As shown, the step-by-step support mechanism includes a second hydraulic expansion sleeve 700, a hydraulic stepping cylinder 400 and an angle locking assembly 800. The second hydraulic expansion sleeve 700 is sleeved outside the vertical connecting column 600, and a transfer arm 701 is configured on the second hydraulic expansion sleeve 700. The angle locking assembly 800 is configured between the cylinder rod 402 of the hydraulic stepping cylinder 400 and the transfer arm 701, and is used to adjust the vertical inclination angle of the hydraulic stepping cylinder 400. A support rod 403 is configured at one end of the angle locking assembly 800 away from the hydraulic stepping cylinder 400, and the axis of the support rod 403 coincides with the axis of the cylinder rod 402. A support seat 1000 is detachably connected to the support rod 403. When the propulsion operation is performed, the angle locking assembly 800 is controlled to release the lock on the cylinder rod 402, and the angle of the hydraulic stepping cylinder 400 is operated to change so that it is converted to a horizontal or slightly inclined upward state, and then the angle locking assembly 800 is controlled to lock the cylinder rod 402. When it is necessary to support and jack up the full-hall bracket 100 to disassemble and assemble the bottom fixing parts of the full-hall bracket 100, the angle locking assembly 800 is controlled to release the lock on the cylinder rod 402, and the angle of the hydraulic stepping cylinder 400 is operated to change so that it is converted to a vertical state, and the angle locking assembly 800 is controlled to lock the cylinder rod 402, and the support seat 1000 is installed on the support rod 403, and the second hydraulic expansion sleeve 700 is released from locking the vertical connecting column 600, and then the hydraulic stepping cylinder is operated. The cylinder 400 moves downward in the vertical direction until the support seat 1000 contacts the ground, and then controls the second hydraulic expansion sleeve 700 to lock the vertical connecting column 600, controls the hydraulic stepping cylinder 400 to move, so that the cylinder body 401 of the hydraulic stepping cylinder 400 is connected with the lower part of the full-hall bracket 100, and then controls the hydraulic stepping cylinder 400 to move to lift the full-hall bracket 100, thereby facilitating the disassembly and assembly of the bottom fixing parts of the full-hall bracket 100.

[0022] As a preferred embodiment of the present invention, Figure 9-11As shown, the angle locking assembly 800 includes a connector 801, two assemblies 803 and two hydraulic opening and closing parts. The connector 801 is a horizontal cylindrical structure. The connector 801 is constructed between the ends of the oil cylinder rod 402 and the support rod 403 that are close to each other, and connects the oil cylinder rod 402 and the support rod 403. The two cylindrical assemblies 803 are respectively constructed at the axial ends of the connector 801, and the axis of each assembly 803 coincides with the axis of the connector 801. A hydraulic cavity is formed in the connector 801, and the hydraulic cavity extends into the two assemblies 803. Connecting joints 805 are respectively constructed on the end faces of the two assemblies 803 that are far away from each other, which are used to be connected to the oil inlet pipe and the oil outlet pipe with the control valve respectively. A plurality of first conduction ports 804 are evenly opened on the circumference of each assembly 803, and these first conduction ports 804 are all connected to the hydraulic cavity. The two hydraulic opening and closing parts are respectively rotatably mounted on the two assemblies 803, and the hydraulic opening and closing parts are connected to the hydraulic cavity through the first conduction port 804 on the corresponding assembly 803. The hydraulic opening and closing parts of this embodiment include a hydraulic sleeve 806 having a hydraulic drive cavity 807, and a plurality of second conduction ports 811 are provided on the inner wall of the hydraulic sleeve 806. These second conduction ports 811 are evenly arranged along the circumference of the hydraulic sleeve 806, and each second conduction port 811 is connected to the corresponding first conduction port 804. A return spring 810 is installed in the hydraulic drive cavity 807, and one end of the movable sleeve 808 away from the connecting body 801 is movably assembled in the hydraulic drive cavity 807 by one end of the hydraulic drive cavity 807. The radial cross section of the outer peripheral wall of the movable sleeve 808 is a regular polygon, and the radial cross section of the inner wall of the hydraulic drive cavity 807 and the outer peripheral wall of the movable sleeve 808 is also a regular polygon, so that the movable sleeve 808 only undergoes axial displacement in the hydraulic drive cavity 807, and no relative rotation occurs. In this embodiment, a second limiting disk 809 is constructed at one end of the movable sleeve 808 close to the connecting body 801, and a first limiting disk 802 is constructed at both axial ends of the connecting body 801, and both ends of the return spring 810 are fixedly connected to the end wall of the movable sleeve 808 and the inner wall of the hydraulic sleeve 806 respectively. The working principle and advantage of this embodiment are: when the hydraulic oil does not enter the hydraulic drive chamber 807, under the action of the return spring 810, the return spring 810 pulls the movable sleeve 808, so that the second limiting disk 809 is separated from the first limiting disk 802, and then the vertical tilt angle of the hydraulic stepping cylinder 400 can be adjusted. When the hydraulic oil is injected into the hydraulic drive chamber 807, the movable sleeve 808 drives the second limiting disk 809 to move toward the first limiting disk 802 under the drive of the hydraulic oil until the second limiting disk 809 and the first limiting disk 802 cooperate with each other, thereby achieving the purpose of locking the vertical tilt angle of the hydraulic stepping cylinder 400.

[0023] As a preferred embodiment of the present invention, Figure 6-8As shown, the gripping mechanism 500 includes an upper connector 501, a connecting sleeve 502, an insert 503, a lower connector 504, a connecting rod 508 and two gripping seats 505. A U-shaped hinge seat 404 is fixedly connected to the end of the cylinder body 401 of the hydraulic stepping cylinder 400, and the opening direction of the U-shaped hinge seat 404 faces away from the hydraulic stepping cylinder 400. The upper connector 501 is hinged to the U-shaped hinge seat 404 through a hinge shaft, and a torsion spring is installed between the hinge shaft and the U-shaped hinge seat 404. The connecting sleeve 502 is constructed at the lower end of the U-shaped hinge seat 404, and the upper end of the insert 503 extends into the connecting sleeve 502 from the lower end of the connecting sleeve 502. A connecting spring is installed in the connecting sleeve 502, and the two ends of the connecting spring are respectively connected to the connecting sleeve 502 and the insert 503. The lower connector 504 of this embodiment is constructed at the lower end of the insert body 503, and the lower connector 504 is movably connected to the two gripping seats 505 through a connecting rod 508. The two gripping seats 505 are arranged side by side, and a second channel 506 is formed between the two gripping seats 505. The lower connector 504 is fixedly connected to the connecting rod 508. The working principle and advantage of this embodiment are: when the hydraulic stepping cylinder 400 is controlled to move and the propulsion operation is performed, under the elastic action of the connecting spring, the insert body 503 drives the two gripping seats 505 to contact the ground, and the upper connector 501 rotates along the hinge axis and abuts against the U-shaped hinge seat 404, thereby locking the position of the upper connector 501. With the continuous action of the hydraulic stepping cylinder 400, the gripping seat 505 gradually grips the ground or the guide rail. In the continuous propulsion process, the gripping seat 505 is relatively stationary with the ground or the guide rail, thereby driving the supporting passive walking mechanism to drive the full-chamber bracket 100 to move. When a stroke of the hydraulic stepping cylinder 400 is completed, the hydraulic stepping cylinder 400 is controlled to shrink. At this time, the cylinder body 401 of the hydraulic stepping cylinder 400 drives the gripping mechanism 500 to move, and the upper connector 501 of the gripping mechanism 500 rotates relative to the U-shaped hinge seat 404, and the U-shaped hinge seat 404 rotates a certain angle, and under the action of the torsion spring, the rotation angle of the gripping mechanism 500 will not be too large, so that after the cylinder body 401 of the hydraulic stepping cylinder 400 returns to its original position, the gripping mechanism 500 can grip the ground or the guide rail during the next propulsion operation. Moreover, when the full-chair support 100 walks on the guide rail, the guide rail is located in the first channel 307 and the second channel 506. In this embodiment, two sliding grooves 510 are symmetrically opened on the circumferential surface of the connecting rod 508, and each sliding groove 510 extends along the axial direction of the connecting rod 508. An assembly hole 511 is opened on each grasping seat 505, and two sliding protrusions 512 are constructed in the assembly hole 511. Each sliding protrusion 512 is assembled in the corresponding sliding groove 510.In this embodiment, buffer springs 509 are respectively mounted at both axial ends of the connecting rod 508, and both ends of each buffer spring 509 are respectively connected to the connecting rod 508 and the end surface of the corresponding gripping seat 505. In this embodiment, since the gripping seat 505 and the connecting rod 508 are axially slidably connected, when the gripping seat 505 is in contact with a hard stone or a ground protrusion or a ground depression, the gripping seat 505 will elastically move along the axis of the connecting rod 508, thereby effectively avoiding obstacles and ensuring that the gripping seat 505 firmly grips the ground. The lower end surface of the gripping seat 505 of this embodiment is an arc surface, and the gripping seat 505 is curved upward toward one end of the hydraulic stepping cylinder 400. In this way, when the gripping seat 505 grips the ground or the bottom surface of the guide rail, the gripping seat 505 gradually grips the target surface through the arc surface in a smooth transition, so that the gripping force is more fully applied to the target surface. And in order to further improve the gripping ability, the measures taken are to gradually increase the contact area, specifically, such as. Figure 7 In the form shown in , the width of the gripping seat 505 increases along the direction away from the hydraulic stepping cylinder 400; and a plurality of gripping teeth 507 are spaced along the extension direction on the lower end surface of the gripping seat 505, and the size of these gripping teeth 507 increases along the direction away from the hydraulic stepping cylinder 400, so as to improve the gripping ability and strength. The gripping teeth 507 of this embodiment are transverse teeth or oblique teeth. When the gripping teeth 507 are oblique teeth, the outer end of the oblique teeth is close to the hydraulic stepping cylinder 400, and the inner end of the oblique teeth is away from the hydraulic stepping cylinder 400. In this way, when gripping, the oblique teeth on the two gripping seats 505 have an oblique outward gripping force, which can effectively improve the gripping stability of the gripping seat 505 and the target surface, and avoid slipping and the like.

[0024] As a preferred embodiment of the present invention, Figure 2As shown, the angle adjustment mechanism 900 includes an adapter sleeve 901 sleeved on the outside of the cylinder body 401 of the hydraulic stepping cylinder 400, the adapter sleeve 901 is movably connected to the cylinder body 401 of the hydraulic stepping cylinder 400, the adapter sleeve 901 is hinged to the connecting cylinder 902 through the connecting ear, and the output end of the connecting cylinder 902 is connected with a fixed joint 903, and the fixed joint 903 can be a sleeve-shaped structure or a clamp. When the connecting cylinder 902 is adjusted to a horizontal state, the fixed joint 903 on the connecting cylinder 902 is connected to the full-chamber bracket 100, and then the connecting cylinder 902 is controlled to drive the cylinder body 401 of the hydraulic stepping cylinder 400 to move, so that the hydraulic stepping cylinder 400 rotates a certain angle along the vertical connecting column 600, and at the same time, the adapter sleeve 901 slides to a corresponding position on the cylinder body 401, thereby achieving the purpose of the hydraulic stepping cylinder 400 driving the walking assembly 300 to rotate a predetermined angle through the vertical connecting column 600. When performing a step-by-step propulsion operation, adjust the connecting cylinder 902 to a vertical state or a state inclined in a vertical direction, and then connect the fixed joint 903 to the full-chamber bracket 100. In this way, the connecting cylinder 902 suspends the hydraulic stepping cylinder 400 through the adapter sleeve 901, so that the hydraulic stepping cylinder 400 is in a horizontal state or a state slightly inclined in a horizontal direction, so that the hydraulic stepping cylinder 400 can perform a step-by-step propulsion action on the full-chamber bracket 100.
