[0042] The present application will be further described in conjunction with the accompanying drawings, so that those skilled in the art can implement it according to the description and drawings.

[0043] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials can be obtained commercially unless otherwise specified; in the description of the present application, the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the present application.

[0044] As shown in Figure 1 and Figure 2 The present application provides a prefabricated assembly component erection equipment relying on forward and backward inverted rail walking, comprising:

[0045] The upper structure comprises a main beam 1 arranged laterally, an electric hoist track 4 arranged longitudinally on the main beam 1, which is arranged to move laterally along the main beam 1, and a pair of electric hoists 5 slidingly fitted on the electric hoist track 4, which are respectively located on both sides of the main beam 1, wherein the electric hoists 5 have a hoisting function, and a crown block 2 is further arranged on the main beam 1, which is used to hoist the prefabricated component 9 through the crown block spreader 8;

[0046] The lower structure comprises a pair of longitudinally spaced legs 3, the upper ends of the pair of legs 3 fixedly supporting the main beam 1, and walking wheels 6 arranged at the lower ends of the pair of legs 3, which are slidingly fitted in the walking track 7, wherein the walking track 7 is arranged in multiple sections and is sequentially laid on the wharf 10 in the longitudinal direction.

[0047] In the above technical solution, the main beam 1 and the pair of legs 3 form a portal structure, and the longitudinal movement of the main beam 1 is realized by the walking of the legs 3, without using the traditional bridge machine, so that the crab 2 on the main beam 1 can hoist and erect the prefabricated component 9 through the lifting appliance 8. The setting of the electric hoist track 4, the electric hoist 5 and the multi-section walking track 7 realizes the continuous longitudinal movement of the main beam 1 and the legs 3 through the simple multi-section walking track 7 according to the construction method proposed in the present application, and the walking track 7 needs to be laid on the whole line, which overcomes the defect that the wharf 10 occupies small or even no space, and solves the problem of erection of the prefabricated component 9 on the wharf 10. The electric hoist track 4 is a common sliding track, and the electric hoist 5 is matched in the electric hoist track 4 and slides in the length direction of the electric hoist track 4, that is, the longitudinal direction of the present application. The crab 2 on the main beam 1 can also be connected to the main beam 1 in a conventional sliding manner, so as to move the crab 2 to a suitable position as needed.

[0048] In another technical solution, the main beam 1 is composed of two box beams arranged side by side in the longitudinal direction, and the two box beams are fixedly connected to expand the main beam 1, and the crab 2 is located at the center of the main beam 1.

[0049] In another technical solution, the crab lifting appliance 8 is a 360° full-rotation lifting appliance, which can realize full-rotation by using a conventional full-rotation lifting appliance, on the one hand, the turning of the prefabricated component 9 can be realized, and on the other hand, the longitudinal movement of the walking track 7 can also be assisted.

[0050] In another technical solution, the walking track 7 is provided with three sections.

[0051] In another technical solution, two groups of lower structures are arranged below the main beam 1, and are respectively located on two different wharfs 10.

[0052] In another technical solution, a telescopic oil cylinder 13 is arranged on the main beam 1, which is used to drive the electric hoist track 4 to move transversely along the main beam 1, and the electric hoist track 4 is generally arranged symmetrically on both sides of the main beam 1.

[0053] In another technical solution, as shown in Figure 3 The limit plate 11 has a pair of horizontal through passages, and the connecting plate 12 is a portal structure, and the opposite two plates are respectively matched through the pair of passages and connected to the side edges of the electric hoist track 4, the top surface center of the connecting plate 12 is connected to the telescopic oil cylinder 13, the telescopic oil cylinder 13 is fixed to the center of the main beam 1, the limit plate 11 is provided with a sliding rail extending away from the telescopic oil cylinder 13 side, the electric hoist track 4 is matched in the sliding rail through the pulley arranged at the bottom end thereof, and the length of the sliding rail is slightly greater than the length of the connecting plate 12.

[0054] In the above technical solution, the electric hoist track 4, because it cannot interfere with the overhead crane 2, has a limited range of movement and moves only on the main beam 1. Therefore, a slide rail is provided on the main beam 1, and a pulley is provided at the bottom of the electric hoist track 4 to facilitate lateral sliding. The telescopic cylinder 13 is fixed away from the overhead crane 2 on the main beam 1. During the movement of the electric hoist track 4, the lateral movement distance of the electric hoist track 4 is limited by the limiting plate 11 to ensure the safety of both the electric hoist track 4 and the overhead crane 2. The connecting plate 12 is provided with a pair of opposing plates fixed on the electric hoist track 4, so that the electric hoist track 4 has two fixed jacking points, which can ensure more stable movement of the electric hoist track 4, which is relatively long in longitudinal width relative to the main beam 1. The length of the slide rail is also limited to a certain extent, which can cooperate with the limiting plate 11 to achieve double protection. In addition, one end of the slide rail is set close to the limiting plate 11, and the other end does not exceed the side of the dock closest to the overhead crane.

[0055] like Figures 4 to 11 In the directions shown, the left side is called the front, and the right side is called the rear.

[0056] like Figures 4 to 11 As shown, the present invention also provides a construction method for a prefabricated assembly component erection equipment that relies on front and rear reverse rails, specifically including the following steps:

[0057] Step 1: Lay the walking track 7 on the dock 10 and install the equipment. The entire equipment moves longitudinally on the walking track 7 by the walking wheels 6 at the lower end of the outriggers 3. At this time, the electric hoist track 4 and the walking track 7 are in the same vertical plane. The main beam 1 is located directly above the middle walking track 7. The electric hoist 5 in front lifts the walking track 7 in front and drives the electric hoist track 4 to move laterally to a position where it is not in the same vertical plane as the walking track 7.

[0058] Step 2: The electric hoist 5 in front lifts the traveling rail 7 in front and moves it backward along the electric hoist rail 4 until the rear side of the traveling rail 7 is located in the middle of the main beam 1.

[0059] Step 3: The entire equipment moves to the rear track 7 using the walking wheels 6 at the lower end of the outriggers 3.

[0060] Step 4: The electric hoist 5 in front lowers the traveling rail 7 in front, and the overhead crane 2 on the main beam 1 lifts the traveling rail 7 in front and rotates it to a position where the electric hoist 5 in the rear can lift the traveling rail 7 in front.

[0061] Step 5: The rear electric hoist 5 moves forward along the electric hoist track 4 and lifts the front travel track 7. The entire equipment moves to the middle travel track 7 by the travel wheels 6 at the lower end of the outrigger 3. Then the rear electric hoist 5 moves backward to the last side of the electric hoist track 4.

[0062] Step six: the rear electric hoist 5 hoists the front traveling track 7, and the electric hoist track 4 is driven to move laterally to the same vertical plane as the traveling track 7;

[0063] Step seven: the whole equipment moves to the rear traveling track 7 by the traveling wheels 6 at the lower end of the supporting legs 3, at this time, the front traveling track 7 hoisted by the rear electric hoist 5 is just located right behind the rear traveling track 7;

[0064] Step eight: the front traveling track 7 is lowered to become the new rear traveling track 7.

[0065] Step nine: the above steps are repeated until the traveling track 7 is longitudinally moved to the position, that is, the whole equipment is longitudinally moved to the position.

[0066] Step ten: after being longitudinally moved to the position, the cranage 2 hoists the prefabricated component 9 to the set position by the sling 8 to erect the wharf 10.

[0067] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, and it can be fully applied to various fields suitable for the present application, and other modifications can be easily realized by those skilled in the art, and therefore the present application is not limited to the specific details and the figures shown and described herein, without departing from the general concept defined by the claims and the equivalent scope.
