Description

Technical Field

[0001] The present invention relates to the technical field of housing construction equipment, and more particularly to a multi-dimensional beam erecting machine which stands on a column top and can lift single and double beams. Background Art

[0002] At present, when assembling prefabricated parts such as beams and beam slabs on construction sites, most of them are done with large cranes, but due to site limitations, the work efficiency is relatively low.

[0003] Even if some construction sites use special lifting equipment for beams and slabs, the position of the equipment legs often requires reinforcement and pre-embedding of the column top foundation, which makes the construction more complicated. In addition, such equipment is mostly used in two-story buildings. If it is used in multi-story buildings, after all components of the current building layer are lifted, a large crane must be used to dismantle the equipment and reinstall it on the pier of the upper layer, which results in low efficiency and high cost.

[0004] The beam erecting machine in the prior art, for example, the publication number CN110397289A is an all-round beam erecting equipment that stands on the top of a house column and has an automatic walking function, including a main arm, the bottom of the main arm is provided with front support legs and rear support legs, a chassis is provided between the front support legs and the rear support legs, the bottom of the chassis is provided with a number of column feet, the chassis is connected to the main arm through a slewing mechanism, a first running mechanism is provided between the slewing mechanism and the main arm, one end of the first running mechanism is connected to the slewing mechanism, and the other end is connected to the main arm, the first running mechanism is used to push the slewing mechanism or the main arm to move, so that the relative position between the chassis and the main arm changes; a lifting mechanism and a second running mechanism are provided on the main arm, the lifting mechanism includes a lifting trolley, the second running mechanism is connected to the lifting trolley, and is used to drive the lifting trolley to move along the longitudinal direction of the main arm. However, this technology cannot realize the automatic upward movement of the beam erecting machine by dividing it into two parts. In addition, the lifting trolley adopts a hanging wheel type and is hung on the lower chord of the main arm, which affects the lifting height. After actual use, it was found that the longitudinal movement through the hole working mode still has certain limitations and needs further optimization. Summary of the Invention

[0049] Example 1:

[0050] See also Figure 1-13As shown, the present invention is a multi-dimensional beam erecting machine that can lift single and double beams on the top of a column, including a movable platform type front auxiliary leg (also serving as a counterweight) 1, a chassis middle leg 2, a slewing mechanism 3, a single and double beam combined main arm segment 4, an upper type lifting trolley 5, a rear auxiliary leg 6 and a chain transmission mechanism driving device 7. The movable platform type front auxiliary leg (also serving as a counterweight) 1 is supported on the front end of the single and double beam combined main arm segment 4 to facilitate passing through the hole, and can also serve as a counterweight when arranged at the rear end of the single and double beam combined main arm segment 4. The chassis middle leg 2 includes a second hydraulic jack 21. The lower part of the chassis middle leg 2 stands on the top of the column through the hydraulic jack 21. The upper type lifting trolley The heavy trolley 5 is arranged on the upper chord 401 of the single-double beam combined main arm segment 4, and the rear auxiliary leg 6 is fixed to the lower part of the rear end of the single-double beam combined main arm segment 4; the single-double beam combined main arm segment 4 includes a double-beam main arm segment 41 in the lifting area with a saddle-type structure cross-connection 43, and a single-beam main arm segment 42 in the non-lifting area. The double-beam main arm segment 41 in the lifting area is a single-piece double-beam structure, and a saddle-type structure cross-connection 43 is provided in the middle; the slewing mechanism 3 includes a large-load-bearing capacity slewing bearing 31 for full-rotation operation of the single-double beam combined main arm segment 4, and the large-load-bearing capacity slewing bearing 31 is fixed to the upper part of the support leg 2 in the chassis.

[0051] The present invention provides a movable platform-type front auxiliary leg (also serving as a counterweight) 1, which is self-moving and self-elevating. During beam erection, the movable platform-type front auxiliary leg (also serving as a counterweight) 1 automatically retracts and hangs from the rear end of the single-beam and double-beam combined main boom segment 4 as a counterweight. During hole crossing, the movable platform-type front auxiliary leg 1 disengages from the single-beam and double-beam combined main boom segment 4 and rests on the ground. It then automatically shifts to the front end of the single-beam and double-beam combined main boom segment 4 to serve as a front fulcrum for reversing the chassis. After all components of the current building level are hoisted, the movable platform-type front auxiliary leg (also serving as a counterweight) can automatically lift the equipment to the next level in two steps to continue construction. The lower portion of the support leg 2 in the chassis rests on the tops of four adjacent existing columns via a second hydraulic jack 21 with a high capacity and long travel, while the upper portion is secured to a slewing mechanism 3. The slewing mechanism 3 is equipped with a high-load-bearing slewing bearing 31 to accommodate the full rotation of the single-beam and double-beam combined main boom segment 4, which can automatically shift back and forth. The single-double beam combined main boom segment 41 in the lifting area adopts a single-piece double beam structure, with a saddle-shaped structure cross link 43 in the middle, and a platform is set on the outside to also serve as a pressure stabilizer. In this way, the upper-mounted lifting trolley 5 can run on the upper chord 401 of the single-double beam combined main boom segment 4, which greatly improves the lifting height. In addition, the whole machine structure is made of Q690 high-strength steel, the whole machine is light in weight, and each leg has little force on the ground, column top or floor.

[0060] As attached Figure 1 、 2 As shown in Figure 8, the slewing mechanism 3 also includes a supporting trolley 32, which is arranged on both sides of the slewing mechanism 3. The supporting trolley 32 is provided with a first automatic chain mechanism 321.

[0064] As attached Figure 11 As shown, the single-beam main boom segment 42 in the non-lifting area is a rectangular truss structure.

[0065] Among them, the main arm segment in the non-lifting area of ​​the present invention adopts a traditional rectangular truss structure to facilitate the passage of people.

[0066] As attached Figure 13 As shown, the movable platform type front auxiliary leg (also serving as a counterweight) 1 includes a longitudinal movement through-hole working mode, and the longitudinal movement through-hole method includes the following steps:

[0067] S101: After the beam is hoisted, the single-beam and double-beam combined main boom segment 4 rotates to a beamless position, and the telescopic column 11 of the movable platform-type front auxiliary leg (which also serves as a counterweight) 1 is fully extended, so that the lower traveling trolley 13 rests on the ground. The telescopic column 11 is then fully retracted and automatically shifted to the vicinity of the leading pier.

[0068] S102: The chain drive mechanism drive device 7 drives the single-beam and double-beam combined main boom segment 4 forward by approximately 4.25 m. The telescopic column 11 on the movable platform-type front auxiliary leg (which also serves as a counterweight) 1 is fully extended, supported on the front end of the single-beam and double-beam combined main boom segment 4 and locked.

The slewing mechanism 3 and the chassis mid-leg 2 are then driven forward 12 meters by the chain drive mechanism to the next section. The piston rods of the four second hydraulic jacks 21 with high capacity and long stroke are extended and supported on the four column tops.

[0070] S104: Retract the rear auxiliary leg 6, release the lock between the telescopic column 11 on the movable platform-type front auxiliary leg (which also serves as a counterweight) 1 and the lower chord 402 of the single-double beam combined main boom segment 4, and then fully retract it;

Then, the second hydraulic jack 21 with large capacity and large stroke set at the tips of the four long legs of the support legs in the chassis stands on the top of the built house column, and then the upper-mounted lifting trolley 5 is used to lift the beams, beam plates and other structures to be erected. With the mutual cooperation of the movable platform-type front auxiliary leg (which also serves as a counterweight) 1, the rear auxiliary leg 6, the chain transmission mechanism drive device 7 and the single-double beam combined main arm segment 4, the longitudinal movement through the hole is completed and the next hole is started.

Support the movable platform-type front auxiliary leg (which also serves as a counterweight) 1 at the center of gravity and lock it. Lift it to the second floor using the telescopic hydraulic jack 12 and place it on a temporary structure for support. Completely retract the movable platform-type front auxiliary leg (which also serves as a counterweight).

[0076] S202: The movable platform-type front auxiliary leg (also serving as a counterweight) 1 is supported at the center of gravity of the slewing and chassis support leg 2 and locked. It is lifted to the second floor by the telescopic hydraulic jack 12 and placed on the pier for support. The movable platform-type front auxiliary leg (also serving as a counterweight) 1 is completely retracted.

[0077] S203: The upper structure is transferred to the slewing structure (including the single-beam and double-beam combined main boom segment 4, winch, upper-mounted hoisting trolley 5, rear auxiliary leg 6, and various component drives) via the movable platform-type front auxiliary leg (which also serves as a counterweight) 1 and locked. Construction of the upper floor can then begin.

[0078] Among them, the movable platform-type front auxiliary leg (which also serves as a counterweight) 1 of the present invention can be automatically displaced and lifted, and can also lift the equipment up to the floor in two times. It has various functions. The double-beam main arm 4 in the lifting area adopts a single-piece double-beam structure. The upper-mounted lifting trolley can run on the upper chord 401 of the single-double-beam combined main arm segment 4, which greatly improves the lifting height. The whole machine can also automatically go up to the upper floor to continue construction without the assistance of external lifting equipment. It is economical and efficient, and greatly facilitates the lifting construction of components of multi-story large buildings (such as warehouses). The rest is exactly the same as Example 1.

[0079] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
