Description

Technical fields:

[0001] This utility model relates to the field of bridge processing equipment technology, and more specifically to a bridge deck lifting device for pedestrian and non-motorized bridges. Background technology:

[0002] Currently, some bridge structures are installed over rivers, with the upper part of the bridge being a vehicle bridge deck and the lower part being a pedestrian and non-motorized vehicle bridge deck. Therefore, during construction, the pedestrian and non-motorized vehicle bridge deck needs to be transported from the water surface and then hoisted onto the lower part of the upper bridge deck.

[0003] The existing method involves manually transporting the pedestrian and non-motorized vehicle bridge deck to the underside of the corresponding bridge structure using a boat, and then lifting it using a bridge deck crane above the bridge. However, since the width of the pedestrian and non-motorized vehicle bridge deck is smaller than the width of the bridge above, the steel wire rope of the bridge deck crane is pulled at an angle during lifting, resulting in an unsatisfactory lifting and stabilization effect. Utility Model Content:

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a bridge deck lifting device for pedestrian and non-motorized vehicle bridges. It uses two equal beam lifting devices to extend the connecting beam, and vertically installs the pedestrian and non-motorized vehicle bridge deck on the connecting beam. Vertical lifting is achieved by vertical lifting through the equal beam lifting devices. The lifting is stable and the use effect is good.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A non-motorized vehicle bridge deck lifting device includes front and rear extending guide rails installed on both sides of the upper plane of the bridge, a driving monorail trolley installed above the two guide rails, and bridge deck cranes fixed on both sides of the upper plane of the driving monorail trolley. The feature is that each bridge deck crane is equipped with two lifting pulley mechanisms.

[0007] The lower part of the two lifting pulley mechanisms on the same side is equipped with a balance beam lifting device, and the non-bridge slab is installed on the two balance beam lifting devices.

[0008] The equalizing beam lifting device includes two corresponding transverse connecting beams at the front and rear, and a supporting connecting beam is welded and fixed between the two transverse connecting beams.

[0009] The two transverse connecting beams of the left-side equalizing beam lifting device and the two transverse connecting beams of the right-side equalizing beam lifting device are all formed with outwardly extending inner insertion holes on their opposite walls. The extended connecting beams are inserted into the inner insertion holes of the corresponding transverse connecting beams and cooperate with the inner insertion holes. The outer side wall of the extended connecting beams is in close contact with the inner side wall of the corresponding inner insertion holes.

[0010] The inner end of the extension connecting beam extends out of the inner end of the corresponding transverse connecting beam. The inner end of the right extension connecting beam is welded and fixed with a connector head, which has multiple connecting pin holes. The front and rear side plates at the inner end of the left extension connecting beam have multiple connecting through holes. The end of the connector head extends into the inner end of the corresponding left extension connecting beam. The connecting pin holes and the corresponding connecting through holes are aligned front and back and inserted into the same pin shaft.

[0011] Lifting blocks are welded and fixed to the left and right sides of the top surface of the two transverse connecting beams of the equalizing beam lifting device. A connecting plate is formed at the bottom of the connecting housing of the lifting pulley mechanism. The upper part of the lifting connecting wire rope is inserted into the middle through hole of the connecting plate, and the lower part of the lifting connecting wire rope is inserted into the middle through hole of the lifting block.

[0012] The outstanding effect of this utility model is:

[0013] Compared with existing technologies, it uses two equal beam lifting devices to extend the connecting beam, vertically installs the non-motorized vehicle bridge deck on the connecting beam, and achieves vertical lifting by lifting the equal beam lifting devices in the vertical direction. Its lifting is stable and its use effect is good. Attached image description:

[0022] For example, see below. Figures 1 to 8As shown, a non-motorized vehicle bridge deck lifting device includes guide rails 11 extending forward and backward on both sides (left and right sides) of the upper plane of the bridge 10. A driving monorail trolley 20 is installed above the two guide rails 11. Bridge deck cranes 30 (which are existing known devices and will not be described in detail here) are fixed on both sides of the upper plane of the driving monorail trolley 20. Each bridge deck crane 30 is equipped with two lifting pulley mechanisms 31.

[0023] The lower part of the two lifting pulley mechanisms 31 on the same side is equipped with a balance beam lifting device 40, and the non-bridge plate 100 is installed on the two balance beam lifting devices 40.

[0024] The equalizing beam lifting device 40 includes two corresponding transverse connecting beams 41 at the front and rear, and a supporting connecting beam 42 is welded and fixed between the two transverse connecting beams 41.

[0025] The two transverse connecting beams 41 of the left-side equalizing beam lifting device 40 and the two transverse connecting beams 41 of the right-side equalizing beam lifting device 40 are all formed with outwardly extending inner insertion holes on their opposite walls. The extended connecting beam 43 is inserted into the inner insertion hole of the corresponding transverse connecting beam 41 and mates with the inner insertion hole. The outer side wall of the extended connecting beam 43 is in close contact with the inner side wall of the corresponding inner insertion hole.

[0026] The inner end of the extension connecting beam 43 extends out of the inner end of the corresponding transverse connecting beam 41. The inner end of the right extension connecting beam 43 is welded and fixed with a connector 44. Multiple connecting pin holes are formed on the connector 44. Multiple connecting through holes 431 are formed on the front and rear side plates at the inner end of the left extension connecting beam 43. The end of the connector 44 extends into the inner end of the corresponding left extension connecting beam 43. The connecting pin holes are aligned with the corresponding connecting through holes 431 and the same pin is inserted.

[0027] The bottom surface of the inner end of the extension connecting beam 43 is fixedly connected to the lower guide wheel seat 45 by bolts, and the lower guide wheel seat 45 is movably connected to the lower guide wheel 46 by a hinge shaft.

[0028] Lifting blocks 411 are welded and fixed to the left and right sides of the top surfaces of the two transverse connecting beams 41 of the equalizing beam lifting device 40. A connecting piece 311 is formed at the bottom of the connecting housing of the lifting pulley mechanism 31. The upper part of the lifting connecting wire rope 1 is inserted into the middle through hole of the connecting piece 311, and the lower part of the lifting connecting wire rope 1 is inserted into the middle through hole of the lifting block 411. The equalizing beam lifting device 40 and the lifting pulley mechanism 31 can be connected through the lifting connecting wire rope 1.

[0029] Furthermore, multiple threaded steel connecting hangers 50 are suspended on the left and right extended support beams 101 of the non-contact bridge deck 100. The upper part of the threaded steel connecting hanger 50 is suspended on the corresponding extended connecting beam 43. In this embodiment, the threaded steel connecting hanger 50 adopts a frame formed by steel welding or forming, with a hook formed on the upper part, which is suspended on the corresponding extended connecting beam 43, while the lower part is fitted on the corresponding support beam 101 to achieve connection. The threaded steel connecting hanger 50 can also adopt other structures, which will not be described in detail here.

[0030] An intermediate connecting beam is welded and fixed between the inner ends of the two extended connecting beams 43 on the same side.

[0031] The left and right front and rear parts of the pedestrian and non-motorized vehicle bridge deck 100 are each fixed with a hanging connecting block 102. The hanging connecting block 102 has a through hole in its center, corresponding to the side connecting blocks 15 fixed on the left and right sides of the bottom of the bridge 10. The side connecting blocks 15 also have through holes in their centers. Subsequently, the hanging connecting blocks 102 are fixed to the corresponding side connecting blocks 15 using steel wire ropes, thereby achieving the hanging installation of the pedestrian and non-motorized vehicle bridge deck 100.

[0032] Furthermore, the top left and right sides of the guide rail 11 are formed with extensions 111, and the top surface of the guide rail 11 is fixed with a front-to-back extending guide support bar 112. The left and right sides of the lower part of the driving monorail trolley 20 are both fixed with a trolley traveling mechanism 21. The outer side wall of the wheel 22 of the trolley traveling mechanism 21 is formed with an annular groove, and the guide support bar 112 is located in the corresponding annular groove. The inner wall of the bottom of the annular groove of the wheel 22 presses against the top surface of the guide support bar 112. The bottom surface of the end of the connecting beam of the trolley traveling mechanism 21 is fixed with a lower guide frame 23. The lower inner side walls of the side guides on the left and right sides of the lower guide frame 23 are movably connected with a guide wheel 24 through a hinge shaft. The guide wheel 24 is located below the corresponding extension 111, and its top surface presses against or is close to the bottom surface of the corresponding extension 111.

[0033] The trolley traveling mechanism 21 includes a connecting beam, with wheels 22 movably connected to the front and rear of the connecting beam via hinge shafts. A reduction motor is fixed on one side of the connecting beam, driving one of the wheels 22 to move. The connecting beam is installed below the driving monorail trolley 20. The structure of the trolley traveling mechanism 21 is basically the same as that of the traveling mechanism of existing bridge cranes or gantry cranes, and is a conventional structure, so it will not be described in detail.

[0034] In this embodiment, the lower inner walls of the side guide portions on both sides of the lower guide frame 23 are movably connected to the guide wheels 24 via hinge shafts. The guide wheels 24 are located below the corresponding extension portions 111, and their top surfaces press against or are close to the bottom surfaces of the corresponding extension portions 111. This ensures that the driving monorail trolley 20 can move back and forth along the two guide rails 11 without tipping over, resulting in good stability.

[0035] The guide rail 11 is fixedly connected to the anchor rod fixed to the upper part of the bridge 10.

[0036] In this embodiment, the pedestrian and non-motorized vehicle bridge deck 100 is first transported to the corresponding position below the bridge 10 via the hull. Then, the bridge deck crane 30 is moved to the lifting position by driving the monorail trolley 20. Next, the two equalizing beam lifting devices 40 are lowered to near the top surface of the pedestrian and non-motorized vehicle bridge deck 100. Then, the extension connecting beam 43 is pulled out from the corresponding transverse connecting beam 41, and the left and right extension connecting beams 43 are connected and fixed by pins. Then, the pedestrian and non-motorized vehicle bridge deck 100 is hung on the extension connecting beam 43 by the precision threaded steel connecting device 50. Then, the pedestrian and non-motorized vehicle bridge deck 100 is vertically lifted and brought close to the bottom of the bridge 10 by pulling the steel wire rope of the bridge deck crane 30. At this time, the hanging connecting block 102 is fixed to the corresponding side connecting block 15 by the steel wire rope, thereby realizing the hanging installation of the pedestrian and non-motorized vehicle bridge deck 100.

[0037] After completion, the pedestrian bridge deck 100 is lowered until its entire weight is supported by the pull of the wire rope. At this point, the pedestrian bridge deck 100 is at its lowest point. Then, the equalizing beam lifting device 40 is lowered further so that the bottom surface of the extension connecting beam 43 is close to the top surface of the pedestrian bridge deck 100. At this point, the threaded steel connecting device 50 is in a non-tensioned state, and its upper hook is no longer attached to the corresponding extension connecting beam 43. It can then be easily removed from the extension connecting beam 43 and the pedestrian bridge deck 100.

[0038] After installation, the pins need to be removed and all the extended connecting beams 43 retracted into the transverse connecting beams 41. Then, by driving the monorail trolley 20, the two equalizing beam lifting devices 40 can be moved to the underside of the bridge 10 to be installed later, for subsequent hoisting of the pedestrian and non-motorized vehicle bridge slab 100. The operation is convenient and the pedestrian and non-motorized vehicle bridge slab 100 can be lifted vertically and stably.

[0039] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
