Description

Technical Field

[0001] The invention relates to the technical field of engineering construction, and in particular to a rotatable support beam removal bracket attached to an inner support column pile. Background Art

[0002] When dismantling the traditional foundation pit support system, the support beams are often temporarily supported by setting up steel saddles, cradles, and buckle brackets on the concrete floor slab that has been poured below. After the support beam concrete is cut into blocks, it is horizontally transferred to the lifting point of the lifting equipment by a forklift, and then lifted out of the foundation pit by the lifting equipment. When there are large openings on the concrete floor slab below the support beam (such as elevator shafts, stairwells, equipment lifting openings, ramp openings, parallel ventilation shaft openings, etc.) or the floor slab height difference is large, the forklift cannot travel, and the temporary supports such as steel saddles, cradles, and buckle brackets are difficult to set up, or even impossible to set up. In addition, the column piles in the internal support system pass through the floor slab, resulting in structural beams being cut off and holes in the floor slab. However, during the dismantling of the support beams, the dynamic load during the horizontal transfer process of the forklift is large, the temporary support is unstable, or the floor slab has insufficient bearing capacity, which can easily lead to safety and quality accidents.

DETAILED DESCRIPTION

[0026] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the embodiments and the accompanying drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 8 As shown, the present invention provides a rotatable support beam dismantling bracket attached to the internal support column pile 7, including a main body 1, an extension body 13, a lifting mechanism 2, a lifting and lifting mechanism 3, an installation mechanism 4 and a rotating mechanism 5. The lifting mechanism 2 is arranged at the bottom of the main body 1, the lifting mechanism 2 is used to lift the support beam, the lifting and lifting mechanism 3 is used to drive the lifting mechanism 2 to rise and fall, the installation mechanism 4 is arranged on the main body 1, and the main body 1 is installed on the external support column pile 7 through the installation mechanism 4. The rotating mechanism 5 is arranged between the main body 1 and the installation mechanism 4, and the rotating mechanism 5 is used to drive the main body 1 to rotate horizontally relative to the installation mechanism 4.

[0028] Specifically, since the traditional foundation pit support system must have support column piles 7 and support beams, wherein the two ends of the support beams are respectively connected to different support column piles 7. When the support beam of the foundation pit support needs to be removed, the present invention is first installed on the support column piles 7 and located above the support beam, and then the lifting mechanism 2 is used to lift the part of the support beam that needs to be removed, and then the support beam is cut by the staff; when the support beam is cut, all its weight is applied to the lifting mechanism 2, and at this time the rotating mechanism 5 is actuated to control the main body 1 to rotate horizontally, thereby moving the support beam to a specific position accessible to a forklift or other lifting equipment, and then the lifting and lifting mechanism 3 is actuated to control the lifting mechanism 2 to descend until the support beam is placed on the ground or on the equipment therein, thereby achieving the effect of safe and convenient disassembly of the support beam.

[0029] In this embodiment, the lifting mechanism 2 includes two lifting components 20 spaced apart at the bottom of the main body 1. The lifting component 20 includes a lifting shaft 21 and a wire rope 22. The two ends of the wire rope 22 are respectively connected to the two ends of the lifting shaft 21, and the lifting shaft 21 is rotatably set on the main body 1.

[0030] That is, the present invention supports the support beam by cooperating with multiple steel wire ropes 22. The steel wire ropes 22 can be equipped with steel plates to contact the support beam to increase the force-bearing area; and the lifting shaft 21 releases or winds the steel wire rope 22 by rotating, thereby achieving the effect of controlling the lifting and lowering of the support beam; the rotation of the lifting shaft 21 is controlled by the lifting and lowering mechanism 3.

[0031] Specifically, two rotating stations 11 are provided at the bottom of the main body 1. The rotating station 11 includes two rotating plates 12. The two ends of the lifting shaft 21 are respectively rotatably provided on the two rotating plates 12. The two ends of the lifting shaft 21 respectively protrude from one end of the two rotating plates 12 away from each other. The two ends of the lifting shaft 21 are respectively installed with limiting members 23, and the wire rope 22 is wound between the rotating plate 12 and the limiting member 23.

[0032] The rotation plate 12 and the limiter 23 are used to limit the position of the wire rope 22 so that the winding position is always limited between the rotation plate 12 and the limiter 23, ensuring the stability of the lifting and lowering of the wire rope 22 and avoiding excessive changes in the winding position that may interfere with subsequent actions.

[0033] Specifically, the lifting drive mechanism includes a lifting motor 31, a first driving wheel 32, a second driving wheel 33, a first transmission wheel 34, a second transmission wheel 35, a first transmission chain 36 and a second transmission chain 37. The lifting motor 31 is installed on the main body 1, the first driving wheel 32 and the second driving wheel 33 are both installed on the rotating shaft of the lifting motor 31, the first transmission wheel 34 and the second transmission wheel 35 are respectively installed on the two lifting shafts 21, the two ends of the first transmission chain 36 are respectively connected to the first driving wheel 32 and the first transmission wheel 34, and the two ends of the second transmission chain 37 are respectively connected to the second driving wheel 33 and the second transmission wheel 35.

[0034] In actual use, since the lifting drive mechanism is arranged between the two lifting shafts 21, the spatial distribution is more uniform. When the lifting motor 31 is in operation, the transmission mechanism composed of the first driving wheel 32, the first transmission wheel 34 and the first transmission chain 36 causes one lifting shaft 21 to rotate, and the transmission mechanism composed of the second driving wheel 33, the second transmission wheel 35 and the second transmission chain 37 causes the other lifting shaft 21 to rotate, thereby achieving the effect of allowing the two steel ropes 22 to rise and fall at the same time, so that the lifting and lowering amplitudes at both ends of the support beam remain basically consistent, thereby avoiding the safety accident of the support beam slipping.

[0035] Preferably, the end of the main body 1 away from the mounting mechanism 4 is detachably connected to an extension body 13, and at least one extension component 14 is provided at the bottom of the extension body 13. The extension component 14 includes an extension shaft 15 and an extension wire rope 16. The extension shaft 15 is rotatably provided on the extension body 13, and the two ends of the extension wire rope 16 are respectively wrapped around the two ends of the extension shaft 15, and the lifting motor 31 is transmission-connected to the extension shaft 15.

[0036] That is, for a support beam that is longer but smaller in height / width, if the weight of the support beam is within the load-bearing range of the present invention, an extension body 13 can be added, that is, the extension component 14 of the extension body 13 is coordinated with the lifting component 20 to lift the support beam, so that a longer length of support beam can be cut at one time for lowering, which is beneficial to improving efficiency.

[0037] The extension assembly 14 described in the embodiment is substantially similar in structure to the lifting assembly 20 and will not be described in detail here.

[0038] Preferably, the lifting drive mechanism further includes a third transmission chain 38 , and the extension shaft 15 and the lifting shaft 21 close to the extension body 13 are respectively provided with driven wheels 39 , and the multiple driven wheels 39 are connected through the third transmission chain 38 .

[0039] That is, when the extension body 13 is added, the extension assembly 14 is driven by the third transmission chain 38 and multiple driven wheels 39 to ensure that all wire ropes 22 and extension wire ropes 16 are paid out or wound at the same rate. To ensure the lifting effect, the lifting motor 31 can be equipped with a speed reducer to increase the output horsepower.

[0040] In this embodiment, the mounting mechanism 4 includes two mounting modules 41, and the mounting module 41 includes an embracing member 42 and a reinforcing member 43. One end of the embracing member 42 is connected to the main body 1, and the other end is provided with a locking position 44; one end of the reinforcing member 43 is fixed to the embracing member 42, and the other end is connected to the main body 1; a lock 45 is detachably provided between the locking positions 44 of the two embracing members 42.

[0041] The two embracing parts 42 cooperate to wrap around the rotating mechanism 5 to achieve fixation, and the rotating mechanism 5 is installed on the supporting column pile 7. By driving the main body 1, the supporting beam is driven to move horizontally, so that the supporting beam can be reliably moved to a position with a larger space for removal.

[0042] Specifically, the locking position 44 can be a hole, and the locking member 45 can be a screw; the locking position 44 can also be a positioning column, and the locking member 45 is a lock buckle that is sleeved on the positioning column. That is, the locking position 44 and the locking member 45 are both conventional structures and will not be described in detail here.

[0043] Specifically, the rotating mechanism 5 includes an annular track 51, a rotating motor 52 and two sliding members 53. The two sliding members 53 are installed in a one-to-one correspondence with the two embracing members 42. The sliding members 53 are slidably arranged on the annular track 51. The rotating motor 52 is installed on the main body 1. The rotating shaft of the rotating motor 52 is installed with a guide member 54. The guide member 54 has a guide groove 55. The annular track 51 is slidably arranged in the guide groove 55. An auxiliary structure 56 for forcing the annular track 51 and the guide groove 55 to move relative to each other is provided between the annular track 51 and the guide groove 55.

[0044] The present invention realizes horizontal rotation guidance by sliding the sliding member 53 on the circular track 51, and the rotating motor 52 applies power to drive the main body 1 to rotate along the circular track 51. The auxiliary structure 56 allows the power of the rotating motor 52 to be reliably converted, thereby achieving the effect of rotating the main body 1.

[0045] Preferably, the auxiliary structure 56 includes an annular tooth portion 57 and two meshing tooth portions 58 . The meshing tooth portion 58 is disposed on the annular track 51 . The annular tooth portion 57 is disposed in the guide groove 55 . The annular tooth portion 57 meshes with the two meshing tooth portions 58 .

[0046] The annular track 51 has a limiting groove 59 . The limiting groove 59 is located between the two toothed portions 58 . The sliding member 53 is slidably disposed in the limiting groove 59 .

[0047] That is, when the rotating motor 52 is activated, the annular tooth portion 57 rotates, and the annular tooth portion 57 engages with the tooth portion 58 to drive the main body 1 to rotate; in addition, during the rotation process, the sliding member 53 always moves in the guide groove 55. Since the height of the sliding member 53 is basically consistent with the height of the guide groove 55, it is ensured that no residual shaking occurs during the rotation of the main body 1, thereby ensuring stable and safe rotation.

[0048] Preferably, a fixing frame 6 is further included, the annular track 51 is arranged on the fixing frame 6 , a rolling plate 61 is arranged at the bottom of the fixing frame 6 , and a roller 17 for rolling on the rolling plate 61 is arranged at the bottom of the main body 1 .

[0049] By providing the roller 17 and the rolling plate 61 , the main body 1 is provided with an additional support point, which improves the stability of the main body 1 and prevents deformation due to forward movement of the center of gravity, thereby ensuring safety.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention is disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the present invention.
