Description

Technical Field

[0001] This utility model relates to the field of rapid hoisting and positioning of composite slabs, and in particular to a rapid hoisting and positioning device for composite slabs. Background Technology

[0002] Composite floor slabs are prefabricated monolithic floor slabs made by combining precast slabs and cast-in-place reinforced concrete. With the development of modern industrial technology, buildings can be manufactured in batches, much like machine production. Prefabricated building components are simply transported to the construction site and assembled. Prefabricated construction began to attract interest in the early 20th century and was finally realized in the 1960s. Britain, France, and the Soviet Union were among the first to experiment with it. Due to its fast construction speed and low production cost, prefabricated buildings quickly spread throughout the world.

[0003] Currently, Chinese patent publication number CN221095918U discloses a rapid hoisting and positioning device for PC laminated panels. The device includes a housing; a transverse limiting plate connected to the housing and located on the front side of the housing; a groove formed on the front surface of the housing; a longitudinal limiting plate located within the groove; an electrically operated telescopic rod connected to the longitudinal limiting plate and located behind it; and a moving mechanism installed at the top and bottom of the groove, which includes a rack. The PC laminated panel rapid hoisting and positioning device provided by this utility model has the advantages of limiting both ends of the PC laminated panel through the setting of the horizontal limiting plate, and limiting the front side of the PC laminated panel by the pushing of the vertical limiting plate, thereby achieving better limiting and leveling operation without the need for manual leveling, thus improving work efficiency. Although the device solves the above problems, the following problems also arise: the device can only limit the laminated panel of a fixed size and cannot adjust the positioning according to the laminated panel of different sizes. In addition, the device has no positioning reference, and there is no cushioning when the device is placed, so the laminated panel is easily damaged. Therefore, a new type of PC laminated panel rapid hoisting and positioning device is needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the problems of existing devices, which can only limit the positioning of stacked plates of fixed size, cannot adjust the positioning according to stacked plates of different sizes, have no positioning reference, and have no cushioning when placing the device, making the stacked plates easily damaged. The present invention provides a quick hoisting and positioning device for stacked plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick hoisting and positioning device for composite plates, comprising a positioning plate, a buffer device fixedly provided on the bottom surface of the positioning plate, a sliding groove fixedly provided on the top surface of the positioning plate, a guide rod fixedly provided inside the sliding groove, a plurality of fixing holes provided on the surface of the guide rod, and a positioning clamping plate sleeved on the outer periphery of the guide rod.

[0006] As a further description of the above technical solution:

[0007] The buffer device includes a base plate, a base, an anti-deviation rod, a buffer seat, a buffer rod, a spiral spring, a support column, and a damping spring. The base is located at the center of the top surface of the base plate. An anti-deviation rod is fixedly installed inside the base. A buffer seat is sleeved around the anti-deviation rod. A buffer rod is fixedly installed on the top surface of the buffer seat. A spiral spring is fixedly installed on one side surface of the buffer seat. Support columns are fixedly installed at the four corners of the top surface of the base plate. Damping springs are fixedly installed on the top surface of the support columns.

[0008] As a further description of the above technical solution:

[0009] The number of support columns and damping springs is four, and the number of bases, anti-deviation rods, buffer seats, buffer rods, and spiral springs is two, and their positions are arranged in a mirror symmetrical manner. The top surfaces of the damping springs and buffer rods are fixedly connected to the positioning plate.

[0010] As a further description of the above technical solution:

[0011] The positioning clamping plate includes a clamping plate, a sliding seat, a positioning platform, and a fixing knob. The sliding seat is fixedly provided on the bottom surface of the clamping plate, and the positioning platform is fixedly provided on one side surface of the clamping plate. The fixing knob is provided on the top of the positioning platform.

[0012] As a further description of the above technical solution:

[0013] The fixing knob passes through the positioning platform, and the position of the fixing knob corresponds to the position of the fixing hole. The fixing knob and the fixing hole are threaded together.

[0014] As a further description of the above technical solution:

[0015] The clamping plate includes a plate body, a protective base, a battery, a laser beam lamp, and a protective cover. The protective base is provided on the top surface of the plate body, the battery is fixedly installed inside the protective base, the laser beam lamp is provided on the top of the battery, and the protective cover is fixedly installed on the top surface of the protective base.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, by pushing the clamping plate, the clamping plate drives the sliding seat to slide along the guide rod in the groove. The guide rod is provided with multiple fixing holes. The operator moves and positions the clamping plate according to the size of the composite plate, so that the clamping plate is close to the edge of the composite plate. Then, the fixing knob is screwed into the corresponding fixing hole on the guide rod. In this way, the positioning clamping plate is fixed in a suitable position, thereby achieving the initial positioning of the composite plate in the plane. This enables the positioning of composite plates of different sizes. The operator can quickly adjust the position of the clamping plate according to the actual size of the composite plate, achieving accurate initial positioning of composite plates of different specifications, improving the versatility of the device, and reducing positioning problems caused by differences in the size of the composite plates.

[0018] By activating the laser beam, the light emitted from the laser beam shines through the transparent tempered glass cover, providing a precise positioning reference. By observing the relative relationship between the laser beam and the edge of the laminated plate, as well as the preset position, operators can make more precise adjustments to the laminated plate, ensuring it is accurately placed on the positioning plate.

[0019] The impact force is transmitted to the buffer device through the positioning plate. At this time, the buffer rod moves downwards as the positioning plate presses down, compressing the spiral spring and damping spring. The spiral spring and damping spring absorb and buffer the impact force through their own elastic deformation. The spiral spring mainly provides buffering force in the horizontal direction, preventing excessive horizontal displacement of the buffer seat, while the damping spring plays a role in buffering and shock absorption in the vertical direction. Working together, they effectively reduce the impact force when placing the composite slab, preventing damage due to excessive impact force, and ensuring that the composite slab can be placed stably on the positioning plate, providing a guarantee for subsequent construction operations.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Referring to Figures 1-4, this utility model provides a quick hoisting and positioning device for composite slabs, including a positioning plate 1. A buffer device 2 is fixedly provided on the bottom surface of the positioning plate 1, and a sliding groove 3 is fixedly provided on the top surface of the positioning plate 1. A guide rod 4 is fixedly provided inside the sliding groove 3, and a plurality of fixing holes 5 are provided on the surface of the guide rod 4. A positioning clamping plate 6 is sleeved on the outer periphery of the guide rod 4.

[0028] The buffer device 2 includes a base plate 201, a base 202, an anti-deviation rod 203, a buffer seat 204, a buffer rod 205, a spiral spring 206, a support column 207, and a damping spring 208. The base 202 is located at the center of the top surface of the base plate 201. The anti-deviation rod 203 is fixedly installed inside the base 202. The buffer seat 204 is sleeved around the anti-deviation rod 203. The buffer rod 205 is fixedly installed on the top surface of the buffer seat 204. The spiral spring 206 is fixedly installed on one side of the buffer seat 204. The support column 207 is fixedly installed at the four corners of the top surface of the base plate 201. The damping spring 208 is fixedly installed on the top surface of the support column 207. The impact force is transmitted to the buffer device 2 via the positioning plate 1. At this time, the buffer rod 205 moves downward as the positioning plate 1 is pressed down, compressing the spiral spring 206 and the damping spring 208. The spiral spring 206 and the damping spring 208 absorb and buffer the impact force through their own elastic deformation. The spiral spring 206 mainly provides buffering force in the horizontal direction to prevent the buffer seat 204 from shifting excessively in the horizontal direction, while the damping spring 208 plays a role in buffering and shock absorption in the vertical direction. The two work together to effectively reduce the impact force when the composite plate is placed, prevent the composite plate from being damaged due to excessive impact force, and ensure that the composite plate can be placed stably on the positioning plate 1, thus providing a guarantee for subsequent construction operations.

[0029] The device has four support columns 207 and four damping springs 208, and two bases 202, two anti-deviation rods 203, two buffer seats 204, two buffer rods 205, and two spiral springs 206, all positioned in a mirror-symmetrical arrangement. The top surfaces of the damping springs 208 and the buffer rods 205 are fixedly connected to the positioning plate 1. The device's buffering area is increased by having four support columns 207 and four damping springs 208, and two bases 202, two anti-deviation rods 203, two buffer seats 204, two buffer rods 205, and two spiral springs 206, all positioned in a mirror-symmetrical arrangement. The top surfaces of the damping springs 208 and the buffer rods 205 are fixedly connected to the positioning plate 1.

[0030] The positioning clamping plate 6 includes a clamping plate 601, a sliding seat 602, a positioning platform 603, and a fixing knob 604. The sliding seat 602 is fixedly mounted on the bottom surface of the clamping plate 601, and the positioning platform 603 is fixedly mounted on one side surface of the clamping plate 601. The fixing knob 604 is mounted on the top of the positioning platform 603. By pushing the clamping plate 601, the clamping plate 601 drives the sliding seat 602 to slide along the guide rod 4 in the slide groove 3. The guide rod 4 is provided with multiple fixing holes 5, which the operator can move according to the size of the stacked plate. Positioning clamping plate 6 is used to bring clamping plate 601 close to the edge of the composite plate. Then, fixing knob 604 is screwed into the corresponding fixing hole 5 on guide rod 4. In this way, positioning clamping plate 6 is fixed in a suitable position, thereby achieving initial positioning of composite plate in the plane. This enables positioning of composite plates of different sizes. Operators can quickly adjust the position of clamping plate according to the actual size of composite plate, achieving accurate initial positioning of composite plates of different specifications, improving the versatility of the device, and reducing positioning problems caused by differences in composite plate size.

[0031] The fixing knob 604 passes through the positioning table 603, and the position of the fixing knob 604 corresponds to the position of the fixing hole 5. The fixing knob 604 is threadedly connected to the fixing hole 5, thereby improving the practicality of the device.

[0032] The clamping plate 601 includes a plate body 6011, a protective seat 6012, a battery 6013, a laser beam lamp 6014, and a protective cover 6015. The protective seat 6012 is mounted on the top surface of the plate body 6011, and the battery 6013 is fixedly mounted inside the protective seat 6012. The laser beam lamp 6014 is mounted on the top of the battery 6013, and the protective cover 6015 is fixedly mounted on the top surface of the protective seat 6012. By turning on the laser beam lamp 6014, the light emitted by the laser beam lamp 6014 shines through the transparent tempered glass cover 6015, providing a precise positioning reference. By observing the relative relationship between the laser beam and the edge of the laminated plate and the preset position, the operator can make more precise adjustments to the position of the laminated plate, ensuring that the laminated plate is accurately placed on the positioning plate 1.

[0033] Working principle: Before use, by pushing the clamping plate 601, the clamping plate 601 drives the sliding seat 602 to slide along the guide rod 4 in the slide groove 3. The guide rod 4 is provided with multiple fixing holes 5. The operator moves and positions the clamping plate 6 according to the size of the composite plate, so that the clamping plate 601 is close to the edge of the composite plate. Then, the fixing knob 604 is screwed into the corresponding fixing hole 5 on the guide rod 4. In this way, the positioning clamping plate 6 is fixed in a suitable position, thereby achieving the initial positioning of the composite plate in the plane, and realizing the positioning of composite plates of different sizes. During the positioning process, the laser beam lamp 6014 is turned on. The light emitted by the laser beam lamp 6014 shines outward through the protective cover 6015, which is made of transparent tempered glass, and can serve as a precise positioning reference. By observing the relative relationship between the laser beam and the edge of the composite plate and the preset position, the operator can make more precise adjustments to the position of the composite plate, ensuring that it is accurately placed on the positioning plate 1. When the composite plate is placed on the positioning plate 1, if there is an impact force, the positioning plate 1 will transfer the impact force to the buffer device 2. At this time, the buffer rod 205 will move downward as the positioning plate 1 is pressed down, compressing the spiral spring 206 and the damping spring 208. The spiral spring 206 and the damping spring 208 absorb and buffer the impact force through their own elastic deformation. The spiral spring 206 mainly provides buffering force in the horizontal direction to prevent the buffer seat 204 from shifting excessively in the horizontal direction, while the damping spring 208 plays a role in buffering and shock absorption in the vertical direction. The two work together to effectively reduce the impact force when the composite plate is placed, prevent the composite plate from being damaged due to excessive impact force, and ensure that the composite plate can be placed stably on the positioning plate 1, providing a guarantee for subsequent construction operations.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
