Description

Technical Field

[0001] This invention relates to the field of building material transportation equipment technology, and in particular to a special lifting device for transporting building materials to prevent swaying. Background Technology

[0002] In the process of building construction, decoration and prefabricated installation, it is often necessary to transfer, lift and install building materials such as panels, door panels, wall panels, frame components and other building materials with a certain height and width. In the existing technology, common equipment often uses ordinary forklifts, lifting platform trucks or simple clamping and lifting devices to complete such operations. Although such equipment can achieve basic material handling and lifting, for large-sized building materials with a high center of gravity or thin shape, it can often only be supported by bottom lifting or single-sided clamping. During the lifting, transfer and positioning process, the materials are prone to back-and-forth swinging, lateral swaying or local tilting. The problem of insufficient stability is more prominent when loading, positioning and installing near walls, facade base or installation reference surface. This not only affects the installation accuracy, but also easily causes damage to the material's corners and surfaces, and in severe cases, it can also bring safety hazards.

[0003] Therefore, it is necessary to invent a special lifting device for transporting building materials to prevent swaying and solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a special lifting device for transporting building materials to prevent swaying, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a special lifting device for transporting anti-sway building materials, comprising a vehicle body, a base frame on the vehicle body, a multi-stage lifting gantry that can extend upward on the base frame, a vertical slide table that can slide up and down along the multi-stage lifting gantry, and an auxiliary clamping pre-positioning mechanism and a main translation clamping mechanism on the vertical slide table; The auxiliary clamping pre-positioning mechanism includes a fixed frame, a slide that guides and cooperates with the fixed frame and can extend or retract relative to the fixed frame, a pre-positioning clamping frame disposed on the slide, and a fork swing seat disposed on the pre-positioning clamping frame and capable of swinging relative to the pre-positioning clamping frame. A fixed rod is fixedly provided at the bottom end of the fork swing seat, and a fork is fixedly provided at the bottom end of the fixed rod. The main translational clamping mechanism includes a clamp mounting frame fixed below the slide, a clamp guide rail disposed on the clamp mounting frame, a clamp slide block sliding along the clamp guide rail, and a clamp arm disposed on the clamp slide block. The pre-positioning clamp is located above the material. The fork is guided to the bottom of the material and forms a pre-positioning support under the cooperation of the clamping arm pushing the material toward the fork, so that the auxiliary clamping pre-positioning mechanism and the main translation clamping mechanism form a surrounding clamp on the material.

[0006] Preferably, the slide and the fixed frame are guided by a slide rail, and a hydraulic cylinder is provided between the slide and the fixed frame to drive the slide to extend or retract relative to the fixed frame. The auxiliary clamping pre-positioning mechanism further includes a telescopic drive component disposed between the slide and the pre-positioning clamping frame, used to drive the pre-positioning clamping frame to extend or retract independently relative to the slide.

[0007] Preferably, the fork swing seat is a triangular swing structure. One corner of the fork swing seat is hinged to the prepositioning clamp, the other corner is hinged to a swing linkage, and the other corner is fixedly connected to a fixed rod. The slide is equipped with a power hydraulic cylinder for driving the swing linkage to swing the fork toward the bottom of the material.

[0008] Preferably, the fixed rod, fork, swing linkage and power hydraulic cylinder are arranged in two sets symmetrically on the left and right. The fork is a single fork structure, and after the fork is inserted into the bottom of the material, it simultaneously undertakes the pre-positioning of the bottom support and the continuous support function.

[0009] Preferably, the main translational clamping mechanism includes two sets of symmetrically arranged clamp slides and clamping arms, and includes a clamping hydraulic cylinder connected to the clamp slides and used to drive the clamp slides to slide in opposite directions along the clamp guide rail, so as to achieve clamping of the material.

[0010] Preferably, one end of the carriage is provided with a top wall-attaching stabilizing mechanism, which includes a swing arm symmetrically arranged on the left and right, a positioning pin disposed at the lower end of the swing arm, a swing hydraulic cylinder for driving the swing arm to swing, a positioning frame disposed at the top of the swing arm, and a guide roller mounted on the positioning frame.

[0011] Preferably, the swing hydraulic cylinder is used to drive the swing arm to swing as a whole, so that the guide roller rolls and fits against the wall or building surface during the lifting or installation phase.

[0012] Preferably, the guide rollers are a row of coaxially mounted rollers, and the guide rollers are deformable rubber rollers to adapt to local changes in the wall or building surface, and continuously roll and adhere to the wall or building surface under the overall swing action of the swing arm.

[0013] Preferably, the base frame is provided with symmetrical buffer seats and buffer springs. The buffer seats are used to fit against the building surface, and the buffer springs are used to provide elastic cushioning when the device is close to the building surface.

[0014] Preferably, the vertical slide table slides and rises along the multi-stage lifting gantry, and a hydraulic cylinder is provided between the vertical slide table and the multi-stage lifting gantry as a lifting power source. The multi-stage lifting gantry can extend upward to expand its height, and the extension of the multi-stage lifting gantry does not affect the sliding and rising of the vertical slide table along the multi-stage lifting gantry.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention, by setting up an auxiliary clamping pre-positioning mechanism and a main translational clamping mechanism, allows the material to be pre-positioned on one side and introduced by the fork before being clamped. Then, the opposite clamping arm pushes the material toward the fork side, so that the fork inserts into the bottom of the material and forms a surrounding clamp together with the main clamping mechanism. The above structures work together to achieve pre-positioning, bottom support and opposite clamping, which significantly improves the stress stability of the material during handling and lifting, and reduces the risk of material tilting, shaking and falling off. 2. This invention sets the fork swing guide structure on the pre-positioning clamp frame, so that the fork first swings into the bottom insertion path of the material, and then the main translation clamping mechanism pushes the material to complete the insertion. This not only improves the smoothness of the insertion process and reduces the rigid impact between the bottom edge of the material and the fork, but also helps to achieve stable insertion in the case of limited bottom gaps of building materials such as plate and frame building materials, thereby enhancing the device's adaptability to different building materials. 3. By setting up a top wall-mounted stabilizing mechanism, the present invention enables the guide rollers to continuously roll and adhere to the wall or building surface during the lifting or installation phase, forming a guiding constraint and anti-sway support on the upper part of the material. During wall-mounted lifting, installation positioning, and vertical operations, the device no longer relies solely on bottom support and lateral clamping to maintain stability, but fully utilizes the building surface to construct an upper stable benchmark, thereby effectively suppressing the swaying, tilting, and shaking of the material during the lifting process, improving installation positioning accuracy, and reducing collision damage to the material's edges and building surfaces.

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

[0027] like Figures 1 to 9 As shown, the anti-sway building material special transport lifting device provided by the present invention is essentially a building material special transport lifting device that can take into account the functions of pre-positioning, bottom support, surrounding clamping and wall anti-sway stability.

[0028] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0029] In this embodiment, a special anti-sway building material transport lifting device includes a vehicle body 1. The vehicle body 1 can adopt an electric drive or internal combustion drive engineering vehicle chassis structure. A walking mechanism is provided at the bottom and a working platform is provided at the top. A base frame 11 is fixedly installed on the vehicle body 1. The base frame 11 is preferably made of box-type welded steel structure or plate beam combined steel structure to ensure that the whole machine has sufficient rigidity and stability when carrying building materials and performing lifting operations. Buffer seats 111 can be symmetrically arranged on the left and right sides of the base frame 11. The buffer seats 111 can adopt a structure of wear-resistant metal seat body combined with elastic contact layer. A buffer spring 112 is connected to the rear side of the buffer seat 111. The buffer spring 112 is used to provide elastic pressure and buffering vibration absorption when the device is close to the building surface to prevent the whole machine or front end mechanism from rigidly colliding with the building surface.

[0030] The base frame 11 is equipped with a multi-stage lifting gantry 12 that can extend upwards. The multi-stage lifting gantry 12 can adopt a multi-stage nested gantry structure, which can be composed of an outer gantry, a middle gantry, and an inner gantry. Each gantry is connected by guide rollers or guide sliders to ensure the guiding accuracy and stress stability of the gantry during the lifting process. The multi-stage lifting gantry 12 is equipped with a vertical slide 211 that can slide up and down along the multi-stage lifting gantry 12. The vertical slide 211 is connected to the multi-stage lifting gantry 12 by a hydraulic cylinder, a wire rope, or other conventional lifting transmission structure. In this embodiment, a hydraulic cylinder is preferably used as the lifting power source for the vertical slide 211, so that the vertical slide 211 can be smoothly lifted up and down along the multi-stage lifting gantry 12.

[0031] The multi-stage lifting gantry 12 can extend upwards to increase its height, and the extension of the gantry 12 does not affect the vertical slide 211 from sliding along it, thus balancing a larger lifting height and better guiding stability.

[0032] The vertical slide 211 is equipped with an auxiliary clamping pre-positioning mechanism 2 and a main translation clamping mechanism 3, which together form a surrounding clamping structure for the building material. At one end of the vertical slide 211, a top wall-adhering stabilizing mechanism 4 is also provided, which is used to form a rolling fit with the wall or building surface during the lifting or installation stage, and to guide and prevent swaying of the upper part of the material.

[0033] The auxiliary clamping pre-positioning mechanism 2 includes a fixed frame 21, a slide 22, a pre-positioning clamping frame 23, a telescopic drive component 231, and a fork swing seat 24. The fixed frame 21 is fixedly installed on the vertical slide 211, preferably using a rectangular frame welded structure. Its main function is to support the slide 22 and its auxiliary mechanisms, and to transfer the load from the front clamping mechanism to the vertical slide 211. The slide 22 and the fixed frame 21 are guided by a slide rail. The fixed frame 21 may be provided with two sets of parallel guide rails, and the slide 22 is provided with... A slider or roller guide that cooperates with the guide rail enables the slide 22 to extend and retract smoothly relative to the fixed frame 21. A hydraulic cylinder is provided between the slide 22 and the fixed frame 21 to drive the slide 22 to extend or retract relative to the fixed frame 21. The hydraulic cylinder is integrated inside the fixed frame 21, the cylinder body is fixed to the fixed frame 21, and the piston rod is connected to the slide 22 to realize the reciprocating extension and retraction of the slide 22. The extension and retraction drive 231 is preferably a hydraulic cylinder, which is used to drive the prepositioning clamp 23 to extend or retract relative to the slide 22 separately.

[0034] A pre-positioning clamp 23 is provided on the slide 22. The pre-positioning clamp 23 is located above the material and mainly serves to support the fork swing seat 24 and related guiding mechanisms, without directly pressing and clamping the side of the material. The fork swing seat 24 is provided inside the pre-positioning clamp 23. In this embodiment, the fork swing seat 24 is preferably a triangular swing structure. One corner is hinged to the pre-positioning clamp 23, and a swing connecting rod 243 is hinged to the other corner. The other corner is fixedly connected to the fixed rod 241. The fixed rod 241 extends downward and the fork 242 is fixedly installed at the bottom end of the fixed rod 241. A power hydraulic cylinder 244 is provided inside the slide 22. One end of the power hydraulic cylinder 244 is hinged to the slide 22, and the other end is connected to the swing connecting rod 243 to drive the swing connecting rod 243 to swing, thereby driving the triangular swing structure fork swing seat 24 to rotate as a whole, and further driving the fixed rod 241 and the fork 242 to swing and guide towards the bottom of the material.

[0035] The fixed rod 241, fork 242, swing linkage 243 and power hydraulic cylinder 244 are all arranged in two sets symmetrically on the left and right. The two forks 242 are respectively located in the insertion areas on the left and right sides of the bottom of the material. Each fork 242 is preferably a single fork structure. The front end of the fork body can be provided with an guide slope or rounded corner transition to reduce the impact on the bottom edge of the material during the introduction. After the fork 242 is inserted into the bottom of the material, it not only undertakes the pre-positioning function of the bottom support of the material, but also continues to undertake part of the bottom support function during subsequent transportation and lifting, thereby enhancing the overall stress stability of the material.

[0036] The main translational clamping mechanism 3 is located on the side opposite to the auxiliary clamping prepositioning mechanism 2. It is mainly used to push the material toward the side of the fork 242 after the fork 242 is introduced, and to clamp and fix the material during the continued movement. The main translational clamping mechanism 3 includes a clamp mounting frame 31, a clamp guide rail 32, a clamp slide 33, a clamp arm 331, and a clamping hydraulic cylinder 34. The two sets of clamp slides 33 are located at the relative positions on the left and right sides of the material, and are driven by the corresponding clamping hydraulic cylinder 34, so that the clamp arm 331 clamps the material from the opposite sides.

[0037] The clamp mounting frame 31 is fixedly installed below the slide 22 and can extend or retract together with the slide 22, the pre-positioning clamp 23 and the fork swing seat 24. The clamp mounting frame 31 is preferably a frame body with a clamp guide rail 32 on it. The clamp guide rail 32 is fixed inside the clamp mounting frame 31 and preferably adopts a linear guide rail, plate slide rail or roller guide rail structure to provide a translational guide base for the clamp slide 33. The clamp slide 33 slides along the clamp guide rail 32 and is equipped with a clamp arm 331. The clamp arm 331 can adopt a plate pressure arm, rubber-coated clamping arm or composite pressure arm structure. The side that contacts the material is preferably provided with an anti-slip layer, an elastic pad layer or a wear-resistant coating layer to improve clamping stability and reduce damage to the material surface.

[0038] The clamping hydraulic cylinder 34 is connected to the clamp slide 33 and is used to drive the clamp slide 33 to translate along the clamp guide rail 32. The main translation clamping mechanism 3 includes two sets of symmetrically arranged clamp slides 33 and clamping arms 331. The two sets of clamp slides 33 slide towards each other under the drive of the clamping hydraulic cylinder 34 to achieve clamping of the material. In this embodiment, the prepositioning clamp 23 is located above the material and does not directly contact the side of the material. Therefore, the clamping effect of the auxiliary clamping prepositioning mechanism 2 on the material is mainly achieved by the fixed rod 241 and the fork 242, while the clamping effect of the main translation clamping mechanism 3 on the material is mainly achieved by the clamp slide 33 and the clamping arm 331. After the two cooperate, the material is clamped between the fork 242 and the clamping arm 331 in the surrounding structure, forming a surrounding clamping state.

[0039] To further suppress the upper swaying of materials during lifting, transport, wall-mounted lifting and installation, a top wall-mounted stabilizing mechanism 4 is provided at one end of the slide 22. The top wall-mounted stabilizing mechanism 4 includes a swing arm 41 symmetrically arranged on the left and right, a positioning pin 411 located at the lower end of the swing arm 41, a swing hydraulic cylinder 412, a positioning frame 42 located at the top of the swing arm 41, and a guide roller 43 installed on the positioning frame 42.

[0040] The swing arm 41 preferably adopts a plate-type swing arm or box-type swing arm structure. The left and right swing arms 41 are hinged to the slide 22 or corresponding mounting base through the positioning pin 411. The swing hydraulic cylinder 412 is set between the slide 22 and the swing arm 41 to drive the swing arm 41 to swing as a whole. The top of the swing arm 41 is fixedly equipped with a positioning frame 42. The positioning frame 42 can adopt a transverse connecting frame or end mounting frame structure. The guide roller 43 is installed on the positioning frame 42. The guide roller 43 is preferably a row of coaxially installed rollers and uses deformable rubber rollers to adapt to local changes in the wall or building surface. During the lifting or installation phase, the swing hydraulic cylinder 412 drives the swing arm 41 to swing as a whole, causing the positioning frame 42 and the guide roller 43 to move closer to the wall or building surface together. Finally, the guide roller 43 forms a continuous rolling contact with the wall or building surface. Since the guide roller 43 is a rubber roller, it can flexibly adapt to the slight unevenness of the wall surface while maintaining rolling contact. This achieves both upper guidance and anti-sway support, and reduces the damage to the building surface caused by rigid friction and collision.

[0041] In summary, during the operation of the device: During the feeding stage, the telescopic hydraulic cylinder located between the fixed frame 21 and the slide 22 is first activated, causing the slide 22, along with the prepositioning clamp 23, the fork swing seat 24, and the clamp mounting frame 31, to extend towards the material. After the clamp mounting frame 31 reaches the side of the material, the telescopic drive component 231 is controlled to push out the prepositioning clamp 23. The prepositioning clamp 23 drives the fork 242 to move, so that the fork 242 reaches the insertion area near the bottom of the material on the side opposite to the clamp mounting frame 31. At this time, the power hydraulic cylinder 244 is activated, driving the fork swing seat 24 to swing as a whole through the swing linkage 243, thereby driving the fixed rod 241 and the fork 242 to be guided towards the bottom of the material, so that the fork 242 enters the insertion path at the bottom of the material. At this time, the fork 242 does not completely rely on its own movement to complete the insertion, but creates the insertion conditions for the subsequent main clamping action.

[0042] Subsequently, the clamping hydraulic cylinder 34 actuates, driving the clamp slide 33 to translate along the clamp guide rail 32. The clamping arm 331 pushes the material from the side opposite to the pre-positioning clamp 23 toward the fork 242. During this relative movement, the fork 242 further inserts into the bottom of the material and finally inserts into the position, providing reliable support for the bottom of the material. Afterward, the clamping hydraulic cylinder 34 continues to actuate, and the clamping arm 331 continues to press against the material, clamping the material between the fork 242 and the clamping arm 331 in a surrounding structure. Thus, the auxiliary clamping pre-positioning mechanism 2 and the main translational clamping mechanism 3 together form a surrounding clamping and holding state.

[0043] After the auxiliary clamping pre-positioning mechanism 2 and the main translation clamping mechanism 3 complete the encircling and clamping of the material and reach the lifting position, the top wall-adhering stabilizing mechanism 4 is activated. The swing hydraulic cylinder 412 drives the swing arm 41 to swing as a whole, so that the guide roller 43 forms a continuous rolling contact with the wall or building surface. Subsequently, through the extension of the multi-stage lifting gantry 12 and the vertical slide 211 sliding along the lifting gantry 12, the clamped building material can be lifted to the target height. During the lifting process, the material is mainly supported by the auxiliary clamping pre-positioning mechanism 2 and the main translation clamping mechanism 3, while the top wall-adhering stabilizing mechanism 4 forms a guide and support on the upper part of the material, effectively suppressing the material's back-and-forth swing, lateral sway and upper shaking, and improving the stability and accuracy of the material when it is installed against the wall or in alignment.

[0044] Once the material reaches the target installation position, the vertical slide 211 can be raised and lowered to align the material with the installation position. Then, the clamping force of the main translation clamping mechanism 3 is released, and the fork swing seat 24 swings back, driving the fork 242 to exit the bottom of the material, thus completing the placement or installation of the material. If the base frame 11 approaches the building surface during the wall installation process, the buffer seat 111 and the buffer spring 112 can absorb and buffer the contact force during the wall installation process, further improving the smoothness and safety of the operation.

[0045] This embodiment is particularly suitable for building materials such as sheet metal, door panels, wall panels, frame components, and other building materials that are relatively large in length and width but relatively thin and prone to swaying during lifting and transport. For building materials of different sizes and weights, the device can be adapted and optimized by adjusting the length of the fork 242, the size of the clamping arm 331, and the position and number of the guide rollers 43.

[0046] The above are merely preferred embodiments of the present invention. Any equivalent substitutions, improvements, and modifications made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
