Description

Technical Field

[0001] The invention relates to the technical field of bridge cantilever cast-in-place construction, and in particular to a walking mechanism and a walking method for a hanging basket construction device. Background Art

[0002] Among the bridge cantilever cast-in-place construction equipment, the traditional construction hanging basket mainly includes two types: diamond hanging basket and triangular hanging basket. The upper structures of the two are only different in the force-bearing structures of the diamond and triangle. Their lower structures are balanced and anchored on the reinforced concrete of the poured section of the bridge. Two I-beam rails are installed. The rolling wheels set at the bottom of the hanging basket are buckled in the I-beam rails and move forward within the length of the I-beam rails. After the pouring of a segment is completed, it is necessary to use a large number of jacks to completely lift the entire hanging basket, and then first remove the anchors of the two I-beam rails on the reinforced concrete, push it forward to the next segment to be poured, anchor and reinforce it, and then completely lower the entire lifted hanging basket to carry out the construction work of the next segment.

[0003] This traditional hanging basket is not only complex in structure and uses a lot of steel materials, but also very cumbersome to install, remove and move. The transportation cost is also higher. A lot of labor will be invested in the use process, which is not conducive to cost control. Summary of the invention

[0047] Please refer to Figures 1 to 17 A walking mechanism for a hanging basket construction device includes a truss main longitudinal beam 11, which is equipped with a plurality of ladder steps 12; a sliding support 2, which is detachably fixed to a box beam 7; the sliding support 2 is hinged with a buckle wheel set 21, and the buckle wheel set 21 is slidably connected to the rear end of the truss main longitudinal beam 11; a front fulcrum 3 is placed on the box beam 7 and slidably connected to the truss main longitudinal beam 11; the front fulcrum 3 is used to support the truss main longitudinal beam 11; the front fulcrum 3 is hinged with a one-way fulcrum pawl 31, and the one-way fulcrum pawl 31 abuts against the ladder step. 12; also includes a pushing component 4, which is slidably connected to the truss main longitudinal beam 11; also includes a power member 5, one end of which is hinged to the front fulcrum 3 and the other end is hinged to the pushing component 4; also includes a jack 6, which is used to lift the truss main longitudinal beam 11; the power member 5 is used to drive the pushing component 4 away from the front fulcrum 3 or to drive the front fulcrum 3 close to the pushing component 4; the pushing component 4 is hinged with a pushing pawl 41; when the pushing component 4 is away from the front fulcrum 3, the pushing pawl 41 can abut against the ladder step 12, so as to drive the truss main longitudinal beam 11 to move.

[0048] In order to simplify the structure of the hanging basket, make the installation and removal of the hanging basket convenient, simplify the operation steps of the hanging basket, reduce the number of on-site construction personnel, and reduce the project cost, this technical solution sets a number of ladder steps 12 on the truss main longitudinal beam 11 of the hanging basket truss 1. In this embodiment, a thick steel plate with a thickness of 24 cm is used as the ladder step 12, and the ladder step 12 is set in the front middle part of the truss main longitudinal beam 11, and the interval between two adjacent ladder steps 12 is 50 cm. In order to facilitate the sliding of the sliding support 2, the front fulcrum 3 and the pushing component 4 along the truss main longitudinal beam 11, the truss main longitudinal beam 11 adopts 2 HN600×200mm steel sections 111, and the center spacing of the steel sections 111 is 30 cm. L80×8mm angle steels 112 are arranged on both outer sides of the steel sections 111 as the hanging basket moving track. In the present technical solution, a sliding support 2, a front fulcrum 3 and a pushing assembly 4 are slidably connected to the main longitudinal beam 11 of the truss. The sliding support 2 is detachably fixed to the box beam 7, that is, the sliding support 2 is fixed to the box beam 7 by an anchor rod. The sliding support 2 is hinged with a reverse wheel group 21, and the reverse wheel group 21 is slidably connected to the rear end of the main longitudinal beam 11 of the truss. The reverse wheel group 21 is hinged on the sliding support 2. When the jack 6 lifts the main longitudinal beam 11 of the truss, the main longitudinal beam 11 of the truss can rotate around the hinge center of the reverse wheel group 21, that is, the front end of the main longitudinal beam 11 of the truss is lifted upward, which is convenient for the front fulcrum 3 and the pushing assembly 4 to crawl along the main longitudinal beam 11 of the truss. In the present technical solution, the power part 5 is configured as a hydraulic screw. In order to realize the control of the action of the hydraulic screw, the present technical solution can also be equipped with an integrated control cabinet. It should be noted that the power part 5 can also be a gear chain mechanism. The front fulcrum 3 is connected to the pushing assembly 4 through a hydraulic screw, which is also the power device for the hanging basket truss 1 to move. In addition, the embodiment of the invention is provided with a plurality of ladder steps 12 on the main longitudinal beam 11 of the truss, and a one-way forward pawl is configured in the front fulcrum 3. The one-way forward pawl enables the front fulcrum 3 to slide forward only but not backward.

[0049] In this embodiment, a push pawl 41 is configured in the push assembly 4, and the push pawl 41 realizes the use of the push assembly 4 to drive the main longitudinal beam 11 of the truss to move. The push pawl 41 is configured as an eccentric structure; the push pawl 41 is configured with a working claw end 411 and an auxiliary claw end 412, and the working claw end 411 can abut against the ladder step 12. By setting the push pawl 41 as an eccentric structure, the heavy part of the eccentric structure is set as the auxiliary claw end 412, and the light part is set as the working claw end 411. When the push pawl 41 is stationary, the working claw end 411 is in a vertically upward state. After the push pawl 41 is moved, the push pawl 41 is stationary after multiple swings, and the working claw end 411 still returns to a vertically upward state. When the working claw end 411 is in a vertically upward state, the working claw end 411 extends into the main longitudinal beam 11 of the truss and abuts against the ladder step 12. Moreover, in this embodiment, the pushing assembly 4 includes a pushing body 42 that is slidably connected to the main longitudinal beam 11 of the truss; it also includes a sliding pin shaft hole 421 and a traveling pin shaft hole 422, which are arranged on the pushing body 42; the sliding pin shaft hole 421 and the traveling pin shaft hole 422 are symmetrically arranged on both sides of the auxiliary claw end 412; it also includes a stop pin shaft 43, which is inserted into the sliding pin shaft hole 421 or the traveling pin shaft hole 422 and abuts against the auxiliary claw end 412. When the stop pin shaft 43 is inserted into the sliding pin shaft hole 421 or the traveling pin shaft hole 422 and the pushing pawl 41 is stationary, the auxiliary claw end 412 of the pushing pawl 41 abuts against the stop pin shaft 43, and the working claw end 411 of the pushing pawl 41 is in a vertically upward state. When the front fulcrum 3 and the pushing assembly 4 crawl along the main longitudinal beam 11 of the truss, the stop pin 43 is inserted into the sliding pin hole 421. If the hydraulic screw is extended, the working claw end 411 of the pushing pawl 41 is blocked by the ladder step 12, and the pushing pawl 41 rotates forward, making it easier for the pushing assembly 4 to crawl along the main longitudinal beam 11 of the truss without hindrance. When the front fulcrum 3 crawls to the next segment position, the front fulcrum 3 is placed again on the surface of the box beam 7, and the stop pin 43 is inserted into the travel pin hole 422. The stop pin 43 and the ladder step 12 are located on the same side of the pushing pawl 41. The working claw end 411 of the pushing pawl 41 is blocked by the ladder step 12 and the auxiliary claw end 412 is blocked by the stop pin 43, so that the pushing pawl 41 cannot rotate, and the pushing component 4 cannot slide along the main longitudinal beam 11 of the truss. If the hydraulic screw is extended, the pushing component 4 uses the abutment between the pushing pawl 41 and the ladder step 12 to drive the main longitudinal beam 11 of the truss to travel.

[0050] It should be noted that when the front fulcrum 3 is placed on the surface of the box beam 7, the weight of the hanging basket truss 1 is concentrated on the front fulcrum 3. When the hydraulic screw is extended, the friction between the front fulcrum 3 and the surface of the box beam 7 is greater than the thrust generated by the hydraulic screw. Therefore, the front fulcrum 3 is fixed, providing a fulcrum point for the hydraulic screw to drive the main longitudinal beam 11 of the truss to move.

[0051] In some embodiments, the push pawl 41 is configured as an axisymmetric structure; the working claw end 411 and the auxiliary claw end 412 are arranged along the same straight line, and the working claw end 411 and the auxiliary claw end 412 are symmetrical about the geometric center of the push pawl 41; the hinge center of the push pawl 41 is arranged toward the working claw end 411. In the present technical solution, the working claw end 411 and the auxiliary claw end 412 are arranged along the same straight line, the push pawl 41 is arranged as an axisymmetric structure, and the push pawl 41 is a structure of regular shape, and the hinge center of the push pawl 41 is arranged toward the working claw end 411, that is, the hinge center is not at the geometric center of the push pawl 41. Fig.13 , the distance from the geometric center of the push pawl 41 to the working claw end is L / 2, the distance from the hinge center of the push pawl 41 to the working claw end is D, and L / 2>D. When the push pawl 41 is stationary, since the mass of the auxiliary claw end 412 is greater than that of the working claw end 411, the working claw end 411 is always in a vertically upward state, and the auxiliary claw end 412 is always at the lower end.

[0052] When it is necessary to move the hanging basket truss 1, first move the sliding support 2 forward to the next segment position, then act on the sliding lifting fulcrum, use the jack 6 to lift the truss main longitudinal beam 11, so that the front fulcrum 3 is separated from the surface of the box beam 7 and is freed, and use the hydraulic screw to realize the crawling of the front fulcrum 3 and the pushing assembly 4 along the truss main longitudinal beam 11. When the front fulcrum 3 moves to the next segment position, remove the jack 6, place the front fulcrum 3 on the surface of the box beam 7, and use the hydraulic screw and the pushing assembly 4 to push the truss main longitudinal beam 11 to the next segment position, so as to realize the movement of the hanging basket truss 1. The present invention sets a sliding support 2, a front fulcrum 3 and a pushing assembly 4, and a hydraulic screw is set between the front fulcrum 3 and the pushing assembly 4 as a power device for the hanging basket to move. Compared with the prior art, the present technical solution adopts a trackless structure, and the sliding support 2, the front fulcrum 3 and the pushing assembly 4 all slide along the main longitudinal beam 11 of the truss, which simplifies the hanging basket structure, makes the hanging basket easy to install and remove, simplifies the operation steps of the hanging basket to move, reduces the number of on-site construction personnel, and reduces the project cost. In addition, the present technical solution sets a hydraulic screw as a power device, and the hydraulic screw can realize the forward movement of the front fulcrum 3 or the movement of the main longitudinal beam 11 of the truss. For several hanging basket trusses 1 constructed with the same box beam 7, an integrated control cabinet can be used to control all the hydraulic screws, thereby improving the synchronization of several hanging basket trusses 1 when moving.

[0053] In some embodiments, the pushing body 42 is provided with a first slide plate 44, which is located between the pushing body 42 and the truss main longitudinal beam 11, and the bottom surface of the truss main longitudinal beam 11 can be attached to the first slide plate 44. When the hydraulic screw drives the pushing assembly 4 to slide along the truss main longitudinal beam 11, or when the hydraulic screw drives the truss main longitudinal beam 11 to move through the pushing assembly 4, the pushing body 42 may rub against the truss main longitudinal beam 11. In order to avoid the wear of the pushing body 42, the technical solution configures the pushing body 42 with a first slide plate 44, which is a stainless steel plate. When the bottom surface of the truss main longitudinal beam 11 contacts the pushing body 42, the bottom surface of the truss main longitudinal beam 11 contacts the first slide plate 44, and the first slide plate 44 plays a role in protecting the pushing body 42.

[0054] In some embodiments, the front fulcrum 3 includes a second slide plate 32 and a fulcrum body 33, and the fulcrum body 33 is slidably connected to the truss main longitudinal beam 11; the second slide plate 32 is located between the fulcrum body 33 and the truss main longitudinal beam 11, and the bottom surface of the truss main longitudinal beam 11 is attached to the second slide plate 32. Since the weight of the hanging basket truss 1 applies pressure to the front fulcrum 3, the truss main longitudinal beam 11 will be squeezed with the fulcrum body 33, and when the front fulcrum 3 slides along the truss main longitudinal beam 11, the fulcrum body 33 may rub against the truss main longitudinal beam 11. In order to avoid pushing the fulcrum to wear, the technical solution configures the second slide plate 32 on the fulcrum body 33, and the second slide plate 32 is a stainless steel plate. When the bottom surface of the truss main longitudinal beam 11 contacts the fulcrum body 33, the bottom surface of the truss main longitudinal beam 11 contacts the second slide plate 32, and the second slide plate 32 plays a role in protecting the fulcrum body 33.

[0055] In some embodiments, the main longitudinal beam 11 of the truss is provided with a sliding lifting fulcrum 13, and the sliding lifting fulcrum 13 is located between the sliding support 2 and the front fulcrum 3; the jack 6 contacts the sliding lifting fulcrum 13; when the jack 6 contacts the sliding lifting fulcrum 13, the jack 6 is arranged close to the front fulcrum 3. In order to ensure that the jack 6 acts on the same position of the main longitudinal beam 11 of the truss each time the hanging basket construction device performs a walking operation, the present technical solution configures a sliding lifting fulcrum 13 on the main longitudinal beam 11 of the truss. When the jack 6 lifts the main longitudinal beam 11 of the truss, the jack 6 replaces the front fulcrum 3, so the sliding lifting fulcrum 13 is arranged close to the front fulcrum 3. It should be noted that the front fulcrum 3 here refers to the front fulcrum 3 located at the original position and not crawling along the main longitudinal beam 11 of the truss.

[0056] A walking method for a hanging basket construction device comprises the following steps:

[0057] S1 moves the sliding support 2 forward to the next segment position and anchors the sliding support 2; the moving position is the same as the length of the block;

[0058] S2 installs the jack 6 to lift the front fulcrum 3 and make the front fulcrum 3 empty.

[0059] S3 uses the pushing assembly 4 to move the front fulcrum 3 forward to the next segment position; removes the jack 6 and anchors the front fulcrum 3; and inserts the stop pin 43 in the pushing assembly 4 into the sliding pin hole 421.

[0060] S4 starts the hydraulic system, and uses the hydraulic screw and the pushing assembly 4 to push the hanging basket forward until the next segment position is in place, and the stop pin shaft 43 in the pushing assembly 4 is inserted into the travel pin shaft hole 422.

[0061] It should be noted that, in step S3, the front fulcrum 3 moves forward to the next segment position including the following steps:

[0062] D1 installs the stop pin into the sliding pin hole 421, as shown in Figure 7 ;

[0063] D2 hydraulic screw extends, pushing the push assembly 4 forward along the truss main longitudinal beam 11 by one gear, such as Figure 8 ;

[0064] D3 hydraulic screw retracts, pulling the front fulcrum 3 forward one gear, repeating steps D2 and D3, moving the front fulcrum 3 into place and anchoring it. Fig. 9 .

[0065] Here, one step refers to moving from one step 12 to the next adjacent step 12, and the distance between two adjacent steps 12 is 50 cm.

[0066] It should be noted that, in step S4, pushing the hanging basket to move includes the following steps:

[0067] After the M1 hydraulic screw is extended 35cm, the stop pin is installed to the travel pin hole 422, and the hydraulic screw is extended another 35cm to push the truss main longitudinal beam 11 forward 35cm. Fig.10 ;

[0068] The M2 hydraulic screw retracts, pulling the push assembly 4 back one gear, such as Fig.11 ;

[0069] The M3 hydraulic screw extends, pulling the truss main longitudinal beam 11 forward 50cm, repeating steps M1 and M2 until the hanging basket moves forward into place. Fig.12 .

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
