Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a plate hoisting fixture used in building construction. Background Art

[0002] Plate lifting clamps are generally made of sturdy and durable materials and have a unique clamping structure design. Through ingenious mechanical devices, they can clamp the plates quickly and stably to ensure that the plates will not slip or shift during lifting and transportation. They are easy to operate and construction workers can easily get started, which greatly improves the efficiency of plate lifting. At the same time, the clamp also focuses on safety design, effectively reducing the risks during the construction process and providing strong guarantees for the smooth progress of construction.

[0003] The Chinese patent publication number CN202245686U discloses a plate lifting fixture, which includes two support plates arranged opposite to each other; U-shaped grooves are opened at corresponding positions of the two support plates, and a baffle is provided at the bottom connecting the two U-shaped grooves; a movable part is provided on one side of the U-shaped groove, and the movable part presses the side edge of the plate accommodated in the U-shaped groove under the action of a lifting belt, and the width of the movable part is greater than the width of the U-shaped groove; a pad is provided on the other side of the U-shaped groove with both ends connected to the support plates, and the surface of the pad facing the U-groove is flush with the side wall of the U-shaped groove.

[0004] The above mentioned method can improve the structural stability and bearing strength of the plate lifting fixture, but it cannot reduce the shaking of the fixture during the lifting process, making the fixture prone to shaking during the lifting process, thereby making its safety unable to be effectively guaranteed. Therefore, the present invention proposes a plate lifting fixture for construction. Utility Model Content

[0005] The purpose of the utility model is to provide a plate lifting clamp for construction. By arranging a connecting rod and a limit block, the connecting rod and the limit block can be pulled along the slide groove to increase the distance between two adjacent fixed blocks. This design cleverly solves the clamping problem of plates of different sizes and can effectively clamp larger plates.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a plate lifting clamp for construction, comprising four fixed blocks, the four fixed blocks being distributed in a rectangular shape, placement grooves being provided in the interiors of the four fixed blocks running through adjacent sides, a pressure block being slidably connected to the interior of the placement groove, and a screw being threadedly connected to the top center position of the fixed block.

[0007] Preferably, one end of the screw rod passes through the interior of the placement groove and is rotatably connected to the top of the pressing block.

[0008] Preferably, connecting rings are fixedly connected to the sides of the four fixing blocks. A iron chain is sleeved inside the connecting ring. The same ends of the four iron chains are fixedly connected to a fixing plate, and a pull ring is fixedly connected to the center position of the top of the fixing plate.

[0009] Preferably, connecting blocks are arranged between adjacent fixing blocks, and the connecting blocks are in a U shape.

[0010] Preferably, a set of sliding grooves are formed inside the connecting block. The set of sliding grooves consists of three pairs of sliding grooves, and the three pairs of sliding grooves are respectively formed inside one vertical plane and two horizontal planes of the connecting block. A limiting block is slidably connected inside the sliding groove, and a connecting rod is fixedly connected to the side of the limiting block.

[0011] Preferably, a spring is fixedly connected to the side of the limiting block and at one end of the sliding groove and on the outer surface of the connecting rod. The diameter of the connecting rod is smaller than that of the limiting block.

[0012] Preferably, the four connecting blocks are fixedly connected to the four fixing blocks in sequence, and the ends of the four groups of connecting rods far from the limiting blocks are fixedly connected to the four fixing blocks in sequence.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1) By placing the plate between the four fixing blocks distributed in a rectangular shape and aligning its four corners with the placement grooves, and then using the method of rotating the screw rod to drive the pressing block to slide downward along the inside of the placement groove, the four corners of the plate can be accurately and firmly clamped and fixed. This fixing method can ensure that the plate maintains a stable position during subsequent operations, avoiding displacement or shaking, thereby ensuring the safety and accuracy of the entire operation process.

[0015] 2) When placing the plate between the four fixing blocks, the connecting rod and the limiting block can be pulled along the sliding groove to increase the distance between adjacent fixing blocks. This design cleverly solves the problem of clamping plates of different sizes, can effectively clamp larger-sized plates, and with the help of the resilience of the spring, not only further enhances the clamping force on the plate, but also can achieve the clamping and alignment of multi-layer plates in the front, back, left, and right directions through the resilience of the plate itself, without the need for prior manual alignment of multi-layer plates, greatly improving the work efficiency and also ensuring the neatness of the multi-layer plate stacking.

[0016] 3) During the lifting process, after connecting the pull ring to the external lifting equipment, the four fixed blocks are distributed in a rectangular shape, making the four chains symmetrical along the center of the fixed plate. In this way, the lifting force of the lifting equipment can be evenly shared on the four fixed blocks. This uniform force distribution method greatly reduces the shaking of the clamp during the lifting process, making the lifting process more stable and safe, and effectively avoiding problems such as plate falling, clamp damage, and harm to the surrounding environment and personnel caused by shaking.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] Combine Figure 1 - Figure 4 A plate lifting fixture for construction includes four fixed blocks 1, which are distributed in a rectangular shape. Placement grooves 7 are opened inside the four fixed blocks 1 and pass through the adjacent sides. The interior of the fixed block 1 is slidably connected to a pressure block 8 in the placement groove 7, and a screw 9 is threadedly connected to the top center position of the fixed block 1.

[0025] During the actual operation process, place the plate between the four fixing blocks 1, and align the four corners of the plate with the four placing grooves 7. Then stack the subsequent plates between the four placing grooves 7 in sequence. Then rotate the four screws 9 in sequence, and drive the four pressing blocks 8 to slide downward along the inside of the four placing grooves 7 respectively, thereby clamping and fixing the four corners of the plate to complete.

[0026] Refer to Figure 2 , one end of the screw 9 penetrates through the inside of the placing groove 7 and is rotatably connected to the top of the pressing block 8.

[0027] Refer to Figure 1 , connecting rings 3 are fixedly connected to the sides of the four fixing blocks 1. A chain 4 is sleeved inside the connecting ring 3. The same ends of the four chains 4 are fixedly connected to a fixing plate 5. A pull ring 6 is fixedly connected to the center position of the top of the fixing plate 5.

[0028] Specifically, connect the pull ring 6 to an external lifting device. Then the lifting device drives the entire fixture to move upward through the pull ring 6 and the four chains 4. Since the four fixing blocks 1 are distributed in a rectangular shape, the four chains 4 are also symmetric about the center of the fixing plate 5. Therefore, the upward force of the lifting device can be evenly distributed to the four fixing blocks 1. Therefore, when the fixture is rising, the situation of its shaking is reduced.

[0029] Refer to Figure 1 、 Figure 3 and Figure 4 , connecting blocks 2 are arranged between adjacent two fixing blocks 1. The connecting blocks 2 are in a U-shaped form.

[0030] Refer to Figure 3 and Figure 4 , a group of sliding grooves are opened inside the connecting block 2. The group of sliding grooves is composed of three pairs of sliding grooves, and the three pairs of sliding grooves are respectively opened inside a vertical plane and two horizontal planes of the connecting block 2. A limiting block 12 is slidably connected inside the sliding groove. A connecting rod 10 is fixedly connected to the side of the limiting block 12.

[0031] Specifically, when placing the plate between the four fixing blocks 1, pull the connecting rod 10 and the limiting block 12 along the sliding groove, and the distance between adjacent two fixing blocks 1 can be increased, so as to clamp a larger-sized plate. Through the resilience of the spring 11, the plate is further clamped. Moreover, through the resilience of the plate, multiple layers of plates can be clamped and aligned in the front, back, left, and right directions, so that it is not necessary to align multiple layers of plates first.

[0032] Refer to Figure 3 and Figure 4 , a spring 11 is fixedly connected to the side of the limiting block 12 and at one end of the sliding groove and on the outer surface of the connecting rod 10. The diameter of the connecting rod 10 is smaller than the diameter of the limiting block 12.

[0033] See Figure 3 and Figure 4 The four connecting blocks 2 are fixedly connected to the four fixing blocks 1 in sequence, and the ends of the four connecting rods 10 away from the limiting block 12 are fixedly connected to the four fixing blocks 1 in sequence.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
