Description

Technical Field

[0001] The present invention relates to the technical field of post-installation construction of a walking jacking machine, and more specifically, to an auxiliary device and a construction method for post-installation construction of a walking jacking machine. Background Art

[0002] A walking jacking machine is a key device used in bridge construction, mainly for the jacking and installation of large bridge segments (such as steel box girders, concrete beams, etc.). Its core feature is the use of a "step-by-step" movement method, and through cyclic "lifting - translation - falling" actions, it pushes the bridge segment to be accurately positioned along a preset trajectory.

[0003] In the existing jacking construction operations, generally after the construction of the jacking piers is completed, the jacking machine is first installed on the top of the jacking piers, and then the bridge segment is placed on the jacking machine for assembly. This construction sequence from bottom to top enables the jacking machine to be hoisted into place from top to bottom by a crane, that is, it can be achieved by using a conventional hoisting process. However, since the assembly of the jacked bridge involves precise hoisting operations and high - requirement welding operations, the assembly construction period is relatively long. Therefore, it is very likely that the jacking machine will be idle for too long, and the long - term idleness of the jacking machine will greatly increase the probability of equipment failure.

[0004] Therefore, with the development of technology, the post - installation construction technology of the jacking machine has gradually emerged in the market, that is, after the construction of the jacking piers is completed, the bridge segment is directly placed on the jacking piers, and a position for placing the jacking machine is reserved between the jacking piers and the bridge segment. After the bridge segment is placed, the jacking machine is then hoisted to the reserved position on the jacking piers, and then precise position adjustment of the bridge segment is carried out. This can significantly reduce the idle time of the jacking machine, thereby reducing the damage probability of the jacking machine.

[0005] However, in the post - installation construction operation of the jacking machine, the jacking machine is hoisted into place from bottom to top. Since the lifting stroke of the jacking machine is short, the reserved installation space between the bridge segment and the jacking pier is relatively narrow. At this time, due to the obstruction of the bridge segment above the jacking pier, the crane cannot directly hoist the jacking machine onto the jacking pier from above. The existing technology usually hoists the jacking machine to an area near the installation position on the jacking pier, and then the staff horizontally pulls the jacking machine to the jacking pier by a chain block hanging under the bottom of the bridge segment. In this operation step, since there is no upward support at the bottom of the jacking machine, it is very easy for the jacking machine to accidentally fall, posing a great safety hazard. Summary of the Invention

[0006] The post-installation construction auxiliary device and construction method for a walking jacking machine provided by the present invention aim to solve the following problem: In the post-installation construction operation of the existing jacking machine, usually the jacking machine is hoisted to an area close to the installation position on the jacking pier, and then the staff horizontally pulls the jacking machine to the jacking pier through a manual chain hoist suspended at the bottom of the bridge segment. In this operation step, since there is no upward support at the bottom of the jacking machine, it is very easy for the jacking machine to accidentally fall, posing a great safety hazard.

[0007] To achieve the above object, the present invention provides the following technical solutions: A post-installation construction auxiliary device for a walking jacking machine, including: a bridge segment and a walking jacking machine body.

[0012] In a preferred embodiment, the legs are vertically installed on the opposite sides of the horizontal bracket and the cross plate, and a reinforcing plate is arranged on the side where the two legs are close to each other.

[0013] In a preferred embodiment, a traction device is arranged at the bottom of the bridge segment. The traction device is located above the upper cross beam, and the output end of the traction device is adapted to the walking jacking machine body.

Detailed implementation manners

[0031] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and cannot be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0032] Referring to the attached Figures 1 to 6 description, the auxiliary assembly mechanism 3 included in the present invention is used to assist in hoisting the walking jacking machine onto the jacking pier 2 for post-installation construction.

[0033] Embodiment 1

[0034] Referring to the attached Figures 1 to 6 description, the auxiliary device for the post-installation construction of the walking jacking machine includes: a bridge segment 1 and a walking jacking machine body 4. A jacking pier 2 is arranged below the bridge segment 1. The jacking pier 2 includes support piles 21 vertically arranged at the bottom of the bridge segment 1, and a pile top distribution beam 22 is horizontally arranged on the support piles 21;

[0035] It should be noted that usually, there are four support piles 21 in a group, and the four support piles 21 are arranged in a rectangular distribution;

[0036] Furthermore, the cross-section of the bridge segment 1 is usually trapezoidal with a wider top and a narrower bottom (not marked in the drawings). Only the part of the bridge segment 1 that will interfere with the hoisting of the walking jacking machine body 4 is shown in this embodiment.

[0037] A upper crossbeam 24 is horizontally arranged on the pile top distribution beam 22. An auxiliary assembly mechanism 3 is arranged on the front side of the upper crossbeam 24. The auxiliary assembly mechanism 3 includes a horizontal bracket 31 horizontally arranged on the front side of the upper crossbeam 24, and the front side of the horizontal bracket 31 extends beyond the foremost end of the bridge segment 1. A plurality of rollers 32 are rotatably arranged on the horizontal bracket 31. The rollers 32 are adapted to the walking jacking machine body 4, and the topmost end of the rollers 32 is flush with the upper surface of the upper crossbeam 24.

[0038] It should be noted that the auxiliary assembly mechanism 3 is detachably connected to both the pile top distribution beam 22 and the upper crossbeam 24. The disassembly and replacement of the auxiliary assembly mechanism 3 can be completed by using bolts, pins or other quick-release structures.

[0039] Furthermore, the topmost end of the roller 32 is higher than the topmost end of the horizontal bracket 31. The rolling friction generated between the walking jacking machine body 4 and the roller 32 during movement is significantly less than the sliding friction directly on the horizontal bracket 31, thus effectively reducing the difficulty of adjusting the position of the walking jacking machine body 4. Moreover, when the walking jacking machine body 4 is on the roller 32, it is in contact with at least two rollers 32 simultaneously.

[0040] In this embodiment, the implementation scenario is specifically as follows: After the auxiliary assembly mechanism 3 is installed, the rear side of the horizontal bracket 31 will be in close contact with the front side of the upper crossbeam 24. The topmost end of the roller 32 will be flush with the upper surface of the upper crossbeam 24, and the roller 32 closest to the upper crossbeam 24 will be as close as possible to the upper crossbeam 24 without interfering with rotation, and the distance between the two is less than 5 cm.

[0041] Embodiment 2

[0042] Based on Embodiment 1, referring to the attached drawings of the specification Figure 2 、 Figure 3 and Figure 6 In this embodiment, a backing plate 33 for connecting the horizontal bracket 31 and the upper crossbeam 24 is provided, which solves the problems of cumbersome installation process and poor stability of the horizontal bracket 31 in the prior art.

[0043] For example, in the prior art, the horizontal bracket 31 is generally directly placed on the wing plate on the front side of the upper crossbeam 24. If the stability of the horizontal bracket 31 needs to be improved in this installation method, an interference fit installation method is generally adopted. However, for both the installation and disassembly of the horizontal bracket 31 using the interference fit installation method, workers need to use hammers or other tools for some knocking. The installation process is cumbersome, but if a clearance fit installation method is adopted to improve the installation efficiency, the stability of the horizontal bracket 31 will be reduced.

[0044] A lower crossbeam 23 is horizontally arranged on the pile top distribution beam 22, and an upper crossbeam 24 is fixedly arranged on the top of the lower crossbeam 23. A backing plate 33 is arranged on one side of the horizontal bracket 31 close to the upper crossbeam 24. The backing plate 33 is horizontally placed on the front wing plate of the upper crossbeam 24, and a number of first positioning holes 25 are symmetrically arranged on the left and right of the front wing plate of the upper crossbeam 24. A number of first fixing holes 36 are symmetrically clamped on the backing plate 33, and the first positioning holes 25 are adapted to the first fixing holes 36.

[0045] It should be noted that, according to the actual situation, the distance between the wing plates of the upper crossbeam 24 is not fixed. Therefore, the backing plate 33 needs to select the corresponding size specification according to the actual situation.

[0046] Similarly to the above content, the size specifications of the first positioning holes 25 and the first fixing holes 36 can also be adjusted adaptively.

[0047] A number of bearing assemblies are arranged on the horizontal bracket 31, and the bearing assemblies are adapted to the corresponding rollers 32.

[0048] It should be noted that the bearing assemblies will be adjusted according to the actual specifications of the rollers 32, which is a well-known and mature technology for those skilled in the art and will not be elaborated in this embodiment.

[0049] In this embodiment, the implementation scenario is specifically as follows: by moving the backing plate 33 to a preset position, and then inserting bolts or pins into the first positioning holes 25 and the corresponding first fixing holes 36, the preliminary installation and fixation of the horizontal bracket 31 can be completed.

[0050] Embodiment 3

[0051] Based on Embodiment 2, referring to the attached drawings of the specification Figure 2 、 Figure 3 and Figure 6 In this embodiment, a cross plate 35 for connecting the horizontal bracket 31 and the pile top distribution beam 22 is provided, which further solves the problem of poor stability of the horizontal bracket 31 in the prior art.

[0052] For example, in the prior art, the cross plate 35 is generally directly placed on the pile top distribution beam 22. When the walking jacking machine body 4 moves on the horizontal bracket 31, since the force application position of the horizontal bracket 31 changes, the cross plate 35 in a free state may move or even warp, posing a great safety hazard.

[0053] There are two legs 34 provided on the front side of the horizontal bracket 31. A cross plate 35 is provided at the bottom end of the leg 34. A number of second fixing holes 37 are symmetrically arranged left and right on the cross plate 35. A number of second positioning holes 26 are symmetrically opened left and right at the top of the front side of the pile cap distribution beam 22. The cross plate 35 is horizontally placed on the top of the front side of the pile cap distribution beam 22, and the second positioning holes 26 are adapted to the second fixing holes 37.

[0054] It should be noted that the size specifications of the second positioning holes 26 and the second fixing holes 37 can also be adjusted adaptively.

[0055] The legs 34 are vertically installed on the opposite sides of the horizontal bracket 31 and the cross plate 35, and a reinforcing plate is provided on the side where the two legs 34 are close to each other.

[0056] It should be noted that, similarly to the above content, the size specifications of the legs 34 and the reinforcing plate can also be adjusted according to the actual situation.

[0057] In this embodiment, the implementation scenario is specifically as follows: by moving the cross plate 35 to a preset position, and then inserting bolts or pins into the second positioning holes 26 and the corresponding second fixing holes 37, all the installation and fixing steps of the horizontal bracket 31 can be completed.

[0058] Embodiment 4

[0059] Based on Embodiment 3, referring to the attached drawings of the specification Figures 1 to 6 , this embodiment provides a traction device 5 for towing the walking jacking machine body 4 from the roller 32 to a preset installation position on the upper cross beam 24, so as to solve the problem that the walking jacking machine body 4 in the prior art is not convenient to adjust the position.

[0060] A traction device 5 is provided at the bottom of the bridge segment 1. The traction device 5 is located above the upper cross beam 24, and the output end of the traction device 5 is adapted to the walking jacking machine body 4.

[0061] It should be noted that the traction device 5 is a manual hoist, and the specification and weight of the walking jacking machine body 4 are within the maximum traction weight range of the manual hoist.

[0062] A lifting ring is provided at the bottom of the bridge segment 1, and the installation end of the traction device 5 is adapted to the lifting ring.

[0063] It should be noted that the lifting ring can be installed at the bottom of the bridge segment 1 by welding or bolt fixing, and the installation position of the lifting ring can be adjusted according to the actual situation.

[0064] A jacking platform 6 is provided at the output end of the walking jacking machine body 4, and the jacking platform 6 is in contact with the bottom of the bridge segment 1.

[0065] It should be noted that since the stroke distance of the output end of the walking jacking machine body 4 in the vertical direction is limited, and sufficient operating space needs to be reserved between the upper cross beam 24 and the bridge segment 1 for installing the walking jacking machine body 4, the versatility of the walking jacking machine body 4 can be improved by installing a matching jacking platform 6. Moreover, the specifications and dimensions of the jacking platform 6 can be adjusted according to the actual situation.

[0066] The front end of the pile top distribution beam 22 extends beyond the front end of the bridge segment 1.

[0067] It should be noted that sufficient installation space needs to be reserved at the front end of the pile top distribution beam 22 for the horizontal support 31 so that the crane can directly hoist the walking jacking machine body 4 onto the roller 32 from above the horizontal support 31.

[0068] In this embodiment, the implementation scenario is specifically as follows: When the walking jacking machine body 4 is hoisted onto the roller 32 and the angle is adjusted, the output end of the traction device 5 is connected to a plurality of evenly distributed connection ends on the walking jacking machine body 4, and then the walking jacking machine body 4 can be moved to the preset installation position by the staff operating the traction device 5.

[0069] Embodiment 5

[0070] Based on Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4, referring to the attached drawings of the specification Figure 7 , this embodiment provides a post-installation construction method for a walking jacking machine, including the following steps:

[0071] Step 1: Pre-assemble the auxiliary assembly mechanism 3 and the traction device 5. First, install the auxiliary assembly mechanism 3 on the pile top distribution beam 22, and fixedly install the backing plate 33 and the cross plate 35 with bolts, and install the traction device 5 on the lifting ring.

[0072] Step 2: Initially hoist the walking jacking machine body 4, and hoist and place the walking jacking machine body 4 onto the roller 32 by a crane.

[0073] Step 3: Secondarily move the walking jacking machine body 4. Fix the output end of the traction device 5 to the preset connection end of the walking jacking machine body 4, and then the staff operates the traction device 5 to transfer the walking jacking machine body 4 from the roller 32 to the preset installation position on the upper cross beam 24, that is, the installation operation of the walking jacking machine body 4 is completed.

[0074] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
