Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a hoisting device for a thin-walled hollow multi-curved plain concrete steel formwork. Background Art

[0002] In the modern construction industry, with the continuous advancement of design concepts and the pursuit of higher architectural aesthetics, fair-faced concrete structures are becoming an increasingly important element in architectural design due to their unique texture and expressiveness. However, achieving high-quality fair-faced concrete structures, especially those with complex spatial forms and thin-walled cavity designs, poses severe challenges to construction technology and equipment. In particular, during the hoisting process, traditional construction methods often face many difficulties, especially when dealing with concrete steel molds and the outer closure panels of steel structures at the same time. The low space utilization efficiency and high safety hazards at the construction site have become key factors restricting project progress and safety.

[0003] In traditional hoisting operations, the installation of concrete steel formwork and external closure panels usually requires the coordinated operation of multiple hoisting machines, which not only requires highly precise on-site command and coordination, but also greatly increases the congestion of the work surface, easily causing collisions between construction equipment, and posing major safety risks. In addition, due to limited working space, the use of large-scale machinery and equipment may also cause unnecessary damage to the built structure and affect the overall building quality. Therefore, how to ensure construction efficiency while ensuring operational safety and reducing mutual interference between construction equipment has become an urgent problem to be solved.

[0004] To this end, the present application specifically proposes a thin-walled hollow multi-curved plain concrete steel formwork hoisting device to solve the above technical problems. Utility Model Content

[0005] The main purpose of the utility model is to solve the above-mentioned deficiencies and provide a thin-walled hollow multi-curved plain concrete steel formwork hoisting device to realize efficient and safe hoisting operations inside buildings. The device can complete the concrete steel formwork hoisting without intersecting with the external closed hoisting operations of the steel structure, thereby effectively avoiding safety hazards during the construction process.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A thin-walled cavity multi-curve plain concrete steel formwork hoisting device comprises: an arc track, which is detachably arranged on a lap platform between the multi-curve plain concrete and a steel structure building; a sliding chassis assembly, which is slidably arranged on the arc track; a locking assembly, which is fixedly arranged on the sliding chassis assembly and is used to lock the position of the sliding chassis assembly on the arc track; and a hoisting assembly, which is fixedly arranged on the top of the sliding chassis assembly and is used to hoist the casting steel formwork of the multi-curve plain concrete.

[0008] Furthermore, the arc track has the same curvature as the multi-curved plain concrete, and the arc track includes two arc guide rails parallel to each other and a connecting plate fixedly arranged at the bottom of the two arc guide rails, and a plurality of mounting holes are evenly arranged on both sides of the connecting plate.

[0009] Furthermore, limiting grooves are provided on both sides of the arc-shaped guide rail.

[0010] Furthermore, the sliding chassis assembly includes a bottom plate, mounting seats fixedly arranged at four corners of the bottom plate, and a pair of rollers rotatably arranged on the mounting seats, and the rollers are plug-fitted with the limiting grooves.

[0011] Furthermore, the locking assembly includes a screw rod rotatably arranged at the bottom of the base plate, a crank handwheel fixedly arranged at one end of the screw rod, two locking plates threadedly connected to the screw rod, and a guide rod passing through both sides of the two locking plates and fixedly connected to the base plate, and the threaded parts of the screw rod and the two locking plates threadedly connected have opposite rotation directions.

[0012] Furthermore, the lifting assembly includes a support base fixedly arranged on the top of the sliding chassis assembly, an electric telescopic cantilever fixedly arranged on the top of the support base, a double-drum winch fixedly arranged at the telescopic end of the electric telescopic cantilever, and a control panel fixedly arranged on the support base for controlling the electric telescopic cantilever and the double-drum winch.

[0013] The beneficial effects of the utility model are embodied in:

[0014] The utility model provides an arc track on a lap platform of thin-walled cavity multi-curved plain concrete and a steel structure building, and provides a sliding chassis assembly and a hoisting assembly on the arc track. The hoisting assembly can be used to lift a steel mold located on the ground to an installation height. The sliding chassis assembly is moved on the arc track, and the hoisting assembly is driven by the sliding chassis assembly to move, so that the steel molds at different positions of the multi-curved plain concrete can be hoisted. Since the hoisting machinery used for the construction of the steel structure building is located on the ground, it is difficult to cause cross operation, thereby ensuring the construction efficiency and improving the construction safety. By providing a locking assembly on the sliding chassis assembly, the position of the sliding chassis assembly on the arc track can be locked, so as to ensure that the sliding chassis assembly remains stable when the hoisting assembly performs the hoisting operation on the steel mold.

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1-7 As shown, the utility model provides a steel formwork hoisting device, which is applied to the hoisting construction of thin-walled cavity multi-curved plain concrete steel formwork, comprising:

[0026] The arc track 1 is detachably arranged on a lap platform 4 between the multi-curved plain concrete 2 and the steel structure building 3;

[0027] A sliding chassis assembly 5 is slidably arranged on the arc track 1;

[0028] A locking assembly 6, fixedly disposed on the sliding chassis assembly 5, and used to lock the position of the sliding chassis assembly 5 on the arc track 1;

[0029] The hoisting assembly 7 is fixedly arranged on the top of the sliding chassis assembly 5 and is used for hoisting the casting steel mold of the multi-curve clear water concrete 2.

[0030] When in use, first install the curved track 1 on the edge of the lap platform 4 close to the multi-curved clear-water concrete 2, then slide the sliding chassis assembly 5 together with the lifting assembly 7 on the curved track 1, and slide the sliding chassis assembly 5 along the curved track 1 to the position where the steel mold needs to be lifted, and after locking the position of the sliding chassis assembly 5 on the curved track 1 by the locking assembly 6, use the lifting assembly 7 to lift the steel mold from the ground to the installation position to realize the lifting of the multi-curved clear-water concrete 2 steel mold. In addition, since the lifting plane is on the lap platform 4, the distance between it and the crane on the ground used for constructing the steel structure building 3 is large, there is no cross-operation wind direction, and the sense of safety in construction is improved. In addition, since the multi-curved plain concrete 2 is divided into multiple sections and poured in sections, the casting steel molds used need to be used in rotation with the casting of different sections. Therefore, the length that the curved track 1 can cover is the same as the length of a single multi-curved plain concrete 2 section. Similar to the casting steel molds, the curved track 1 is disassembled, assembled and moved with the pouring of different sections to reduce the laying cost of the curved track 1.

[0031] It needs to be explained that Figure 1 and Figure 2 The multi-curved plain concrete 2 shown in the figure is in a state after casting and demolding, not in a state to be installed with a casting steel mold. It is only used as a schematic representation of its specific position and structure, not as a schematic representation of its actual state.

[0032] In one embodiment, the arc track 1 has the same arc as the multi-curved plain concrete 2. The arc track 1 includes two arc guide rails 101 parallel to each other and a connecting plate 102 fixedly arranged at the bottom of the two arc guide rails 101. A plurality of mounting holes 103 are evenly arranged on both sides of the connecting plate 102. With this design, the arc track 1 can be installed by passing anchor bolts through the mounting holes 103 and fixing them on the ground of the lap platform 4; the connecting plate 102 connects the two arc guide rails 101 to form a whole, and the two arc guide rails 101 provide a relatively stable platform for the sliding chassis assembly 5 to slide thereon.

[0033] In one embodiment, two sides of the arc-shaped guide rail 101 are provided with limiting grooves 104 , and the rollers 53 in the sliding chassis assembly 5 can be clamped in the limiting grooves 104 .

[0034] In one embodiment, the sliding chassis assembly 5 includes a bottom plate 51, mounting seats 52 fixedly arranged at the four corners of the bottom plate 51, and a pair of rollers 53 rotatably arranged on the mounting seats 52, and the rollers 53 are plugged and matched with the limiting grooves 104. With this design, the rollers 53 are clamped in the limiting grooves 104, and the bottom plate 51 is pushed, so that the rollers 53 can roll along the limiting grooves 104, thereby realizing the movement of the sliding chassis assembly 5 on the arc track 1.

[0035] In one embodiment, the locking assembly 6 comprises a screw rod 61 rotatably arranged at the bottom of the base plate 51, a crank hand wheel 62 fixedly arranged at one end of the screw rod 61, two locking plates 63 threadedly connected to the screw rod 61, and a guide rod 64 penetrating the two locking plates 63 on both sides and fixedly connected to the base plate 51, and the threaded rotation direction of the screw rod 61 and the two locking plates 63 is opposite. With this design, the screw rod 61 is rotated by turning the crank hand wheel 62, and the screw rod 61 drives the two locking plates 63 to move in the opposite direction along the direction of the guide rod 64. When it is necessary to lock the position of the sliding chassis assembly 5 on the arc track 1, the two locking plates 63 are moved in the direction close to the arc guide rail 101 until they are pressed against the side wall of the arc guide rail 101. Under the action of the friction between the locking plates 63 and the side wall of the arc guide rail 101, the sliding chassis assembly 5 is difficult to move on the arc track 1.

[0036] In one embodiment, the hoisting assembly 7 includes a support seat 71 fixedly arranged on the top of the sliding chassis assembly 5, an electric telescopic boom 72 fixedly arranged on the top of the support seat 71, a double-drum hoist 73 fixedly arranged at the telescopic end of the electric telescopic boom 72, and a control panel 74 fixedly arranged on the support seat 71 for controlling the electric telescopic boom 72 and the double-drum hoist 73. With this design, the telescopic movement of the electric telescopic boom 72 and the forward and reverse rotation of the double-drum hoist 73 can be controlled by the control panel 74, which is convenient for hoisting the steel mold of the multi-bend clear-faced concrete 2. The double-drum hoist 73 is used here to hoist the steel mold at two fixed points to prevent the steel mold from rotating excessively during the lifting process and making it inconvenient to install.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0038] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0039] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
