Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a hoisting frame that facilitates installation on exterior walls. Background Technology

[0002] Metal panel cladding is widely used in the construction industry. However, the hoisting of physical installation materials during the construction process is often a major challenge due to site and machinery limitations. For example, in large industrial plants, the exterior walls are mostly made of metal panels, with a single exterior wall area reaching tens of thousands of square meters. The hoisting of metal cladding materials in high-rise buildings has also been a constraint on the construction industry's development requirements for lean construction.

[0003] Meanwhile, for high-tech electronic factories, technological products are constantly evolving and product production lines are continuously being updated. The shorter the construction cycle of such buildings, the more advantageous they can be in the market. However, the exterior wall design of industrial factories is often metal panel exterior walls; traditional brick and stone walls have long construction cycles. These conditions limit the installation speed of the exterior walls of such buildings and affect the construction progress. Therefore, this utility model proposes a metal exterior wall material hoisting device to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting frame that is easy to install on the exterior wall, to solve the technical problem of poor adaptability of existing hoisting frames, and to solve the problem that existing hoisting structures need to be installed and fixed through roof embedded parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hoisting frame for easy installation on an exterior wall, fixed to a parapet wall, is characterized by comprising a rope winding assembly and a snap-fit ​​hanger assembly. The rope winding assembly includes a mounting plate, a motor, a drum, and a steel rope wound around the outer surface of the drum. The snap-fit ​​hanger assembly includes a U-shaped clamp secured to the parapet wall and an L-shaped hanger secured to the U-shaped clamp. The U-shaped clamp includes an L-shaped clamping plate, a vertical plate, and several sets of spring assemblies connecting the vertical part of the L-shaped clamping plate and the vertical plate. The top surface of the vertical part of the L-shaped hanger is provided with a fixed pulley for the steel rope to pass around. The bottom surface of the horizontal part of the L-shaped hanger is symmetrically provided with two clamping plates, which are respectively snapped onto the two side walls of the U-shaped clamping plate.

[0007] More preferably, the mounting plate is provided with a counterweight groove, and a counterweight block is placed in the counterweight groove.

[0008] Furthermore, the vertical part of the L-shaped card plate and the outer side of the vertical plate are provided with U-shaped card slots, and the openings of the two U-shaped card slots are arranged opposite each other, and the two sides of the card plate are vertically engaged in the U-shaped card slots.

[0009] Furthermore, the U-shaped slot is provided with a limiting member, which includes a wedge block, a compression spring and a pulling plate. The plate is provided with a slot at a position corresponding to the limiting member. The wedge block passes through the outer wall of the U-shaped slot and its end is limited to the slot. The two ends of the compression spring are fixed to the pulling plate and the outer wall of the U-shaped slot, respectively.

[0010] Furthermore, the spring assembly includes a slide rod, a spring, and a slide rail. The slide rail is located inside the horizontal part of the L-shaped plate.

[0023] To make the technical means, innovative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0024] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0025] A type of hoisting frame that is easy to install on exterior walls, such as Figures 1-6 As shown, the device fixed to the parapet wall 1 includes a rope winding assembly 2 and a snap-fit ​​hanger assembly 3. The rope winding assembly 2 includes a mounting plate 21, a motor 22, a drum 23, and a steel rope 24 wound around the outer surface of the drum 23. The snap-fit ​​hanger assembly 3 includes a U-shaped clamp fastened to the parapet wall 1 and an L-shaped hanger fastened to the U-shaped clamp. The U-shaped clamp includes an L-shaped clamping plate 31, a vertical plate 32, and several sets of spring assemblies 33 connecting the vertical part of the L-shaped clamping plate 31 and the vertical plate 32. The top surface of the vertical part of the L-shaped hanger is provided with a spring for the steel rope. The rope 24 passes around the fixed pulley 34; the bottom of the horizontal part of the L-shaped lifting member is symmetrically provided with two clamping plates 35, which are respectively clamped on the two side walls of the U-shaped clamping member, that is, clamped on the vertical part of the L-shaped clamping plate 31 and the vertical plate 32. The mounting plate 21 is provided with a counterweight groove 26, and a counterweight block 25 is placed in the counterweight groove 26. The vertical part of the L-shaped clamping plate 31 and the outer side plate of the vertical plate 32 are both provided with U-shaped grooves 36. The openings of the two U-shaped grooves 36 are arranged opposite each other, and the two sides of the clamping plate 35 are vertically clamped in the U-shaped grooves 36.

[0026] The U-shaped slot 36 is provided with a limiting member 37, which includes a wedge block 371, a compression spring 372 and a pulling plate 373. The card plate 35 is provided with a slot 38 at the position corresponding to the limiting member 37. The wedge block 371 passes through the outer wall of the U-shaped slot 36 and its end is limited to the slot 38. The two ends of the compression spring 372 are fixed to the pulling plate 373 and the outer wall of the U-shaped slot 36, respectively.

[0027] The spring assembly 33 includes a slide rod, a spring, and a slide rail. The slide rail is located inside the horizontal part of the L-shaped clamping plate 31. When the spring is a compression spring, the spring is sleeved on the slide rod, and both ends are fixed to the bottom wall of the slide rail and the vertical plate 32, respectively. One end of the slide rod is fixed to the vertical plate 32, and the other end passes through the bottom wall and is limited to the outside of the slide rail. The compression spring serves to connect the left and right sides of the structure. A baffle is provided at the end of the slide rod that passes through the bottom wall. The diameter of the baffle is larger than the diameter of the slide rail. The baffle mainly limits the slide rod to the left and right sides within the slide rail.

[0028] The top surface of the vertical part of the L-shaped lifting member is provided with a limiting hole for limiting the steel rope 24, and a support plate 39 is provided between the two U-shaped slots 36. The end of the steel rope 24 that passes over the fixed pulley 34 is provided with a hook 4.

[0029] The drum in this solution is a conventional device of existing technology, which mainly consists of a support base, a winding sleeve and a rotating shaft. It is used for winding and unwinding steel rope. Its model and style can be selected and designed according to the actual situation. This solution will not provide much explanation.

[0030] Based on the actual site conditions, place the counterweight inside the counterweight groove to prevent the equipment from detaching during the subsequent winding process. Then, take out the steel rope from the drum, pass it through the fixed pulley and the limit hole in sequence, and hook it onto the lifting ring with the hook to facilitate the subsequent lifting of the main body. After preparation, start the motor. At this time, the output end of the motor drives the rotating shaft of the drum to rotate through the coupling, thereby pulling the steel rope to lift the main body.

[0031] The working principle of this utility model is as follows: The L-shaped clamp is pulled according to the dimensions of the parapet wall. At this time, the clamp pulls the sliding rod, causing it to slide inside the track. The baffle mainly prevents the sliding rod from leaving the track. After the L-shaped clamp is pulled to a suitable distance, the U-shaped clip is placed on the parapet wall to fix it in place. Then, the L-shaped hanger slides into the U-shaped slot 36 along the groove on the U-shaped slot 36. During the insertion process, the wedge block in the limiting member 37 is pulled open, causing the wedge block to move to both sides until it enters the slot for fixation. According to the actual situation on site, the counterweight is placed inside the counterweight groove. Then, the steel rope on the drum is taken out and passed through the fixed pulley and the limit hole in sequence, and the part to be lifted (the perforated metal plate) is hooked on the hook to facilitate the subsequent lifting of the part. After preparation, the motor is started. At this time, the output end of the motor drives the rotating shaft of the drum through the coupling to rotate, thereby pulling the steel rope to lift the part to be lifted. The metal plate is relatively light in weight compared with the brick wall, and the assembled lifting frame described in this application can be used for lifting. Due to the special structure of this application, it is not easy to lift heavy precast concrete wall panels.

[0032] The parts not covered in this utility model are the same as or can be implemented using existing technologies.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
