Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a building material lifting device. Background Art

[0002] Building materials are a general term for materials used in civil engineering and construction engineering, including wood, stone, plate, tube / rod-shaped materials, etc., and the above materials, especially with the development of prefabricated buildings, will often use lifting devices to lift the building materials from the ground or a certain floor to a higher floor. The lifting device usually includes a crane, and the crane is connected to one or more hooks by a wire rope. For plates with a larger volume and area, it is usually necessary to pre-embed a plurality of lifting rings on the surface of the plate and lift the plate by the hook. However, for plates with a smaller volume and a narrower width, pre-embedded lifting rings on the surface of the plate are likely to affect the strength of the plate, and the surface of the plate is likely to be damaged when the lifting rings are removed after the lifting is completed. In addition, when lifting bundles of rod-shaped building materials, it is necessary to set multiple lifting points on the outside of the bundles of rod-shaped building materials in combination with other components only by using wire ropes and hooks, which is more troublesome to operate. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a building material lifting device.

[0004] The technical solution of this utility model is as follows:

[0005] A building material lifting device comprises a plurality of steel wire ropes connected to a crane, wherein the bottom ends of the plurality of steel wire ropes are connected to two U-shaped channel steels arranged at intervals through a connecting piece, and the connecting piece can slide along the length direction of the U-shaped channel steel and can be fixed at multiple positions, and the openings of the two U-shaped channel steels are arranged to be opposite to each other;

[0008] The ends of the two second connecting frames are both fixedly connected with L-shaped clamping plates, and the openings of the two L-shaped clamping plates are arranged opposite to each other.

[0009] The connection method between the U-shaped channel steel and the wire rope is that the connecting part includes a sliding plate slidably arranged between the two U-shaped channel steels and connected to the wire rope, and a groove is opened at the bottom of the sliding plate, and a limiting plate is arranged through the groove to interfere with the bottom of the U-shaped channel steel.

[0010] The connection method between the wire rope and the sliding plate is that the bottom ends of multiple wire ropes are all wound into a ring shape, and the connecting piece also includes a connecting buckle connected to the ring position of the wire rope, which is connected to the upper end of the sliding plate through the connecting buckle.

[0011] In order to increase the contact area with the plate or rod-shaped material and ensure stability during lifting, the inner side of the L-shaped clamp is detachably connected to an L-shaped support pad, and the width of the L-shaped drag pad is greater than the width of the L-shaped clamp.

[0012] In order to facilitate the clamping of the materials to be hoisted, the L-shaped clamping plate is tilted relative to the second connecting frame, and the inclination angle of the two is 110°-150°.

[0013] In order to improve the tightness of the two L-shaped clamps when they are clamped, a hook is hinged at the hinged end of one of the second connecting frames, and a hanging rod adapted to the hook is arranged at the end of the other second connecting frame.

[0016] In order to facilitate the adjustment of the position of the mounting frame and the sliding plate, to adjust the horizontal distance between the L-shaped clamps, and to adapt to the clamping of plates of different lengths, a plurality of threaded holes are evenly opened on the side of the U-shaped channel steel, and the mounting frame and the sliding plate are fixed to the U-shaped channel steel by locking bolts respectively.

[0017] The beneficial effects of the utility model are as follows: the utility model is a building material lifting device, which firstly realizes the lifting of building materials by connecting a crane with a steel wire rope and cooperating with a plurality of groups of L-shaped clamps connected under the U-shaped channel steel; secondly, by using two groups of L-shaped clamps respectively connected at the bottom of two groups of mounting frames, it is possible to clamp and fix plates with smaller volume and narrower width, so that the lifting device can avoid the form of pre-embedded lifting rings on the surface of the plates to complete the lifting of the plates from low to high, and bundles of rod-shaped materials can also be placed between the L-shaped clamps, which can avoid damage to the plates and ensure the strength of the plates on the one hand, and on the other hand, cooperate with the L-shaped baffle to fix and limit the plates and rod-shaped materials stably, conveniently and quickly; finally, by using a mounting frame that can be fixed to the U-shaped channel steel at multiple positions, it is possible to adjust the distance between the L-row clamps connected at the bottom of the two groups of mounting frames, so as to adapt to the lifting of plates of different lengths.

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0026] Example

[0027] As mentioned in the background technology, during the construction process, most building materials need to be hoisted. For plates with larger volume and area, it is usually adopted to pre-embed lifting rings on the surface of the plates, and then connect them with the hooks 12 of the crane for hoisting. However, for some plates with smaller volume and narrower width, the pre-embedded lifting rings and the removal of the lifting rings will have a greater impact on the strength of the plates, and the hoisting procedures for rod-shaped building materials such as steel bars are also relatively cumbersome. Therefore, the inventor used existing components for design and invented a new type of lifting device, which is described in detail below with reference to the drawings.

[0028] This embodiment provides a building material lifting device, see Figure 1 and Figure 2, including multiple steel wire ropes 1 connected to a crane. The upper ends of the multiple steel wire ropes 1 are all wound into a ring shape and can be connected to the output end of the crane by means of a hook or other methods. The connection here can adopt the existing technology and will not be elaborated redundantly. The bottoms of the multiple steel wire ropes 1 are commonly connected with two U-shaped steel channels 2 arranged at intervals through a connecting piece. The connecting piece connects the steel wire rope 1 with the U-shaped steel channel 2, and the connecting piece can slide along the length direction of the U-shaped steel channel 2 and can be fixed at multiple positions. Moreover, the openings of the two U-shaped steel channels 2 face away from each other, that is, the flat sides of the two U-shaped steel channels 2 are arranged opposite to each other with a certain interval distance therebetween.

[0029] The connection between the bottom end of the steel wire rope 1 and the U-shaped steel channel 2 is mainly realized in the following way. Among them, the connecting piece includes a sliding plate 7 slidably arranged between the two U-shaped steel channels 2 and connected to the steel wire rope 1. The sliding plate 7 can be fixed to the U-shaped steel channel 2 at multiple different positions. In this solution, the number of both the mounting frames 3 and the steel wire ropes 1 is set to two groups. And in order to improve stability, the two groups of sliding plates 7 can be respectively arranged to include two, which are arranged in contact with each other between the two U-shaped steel channels 2. The bottom ends of the two steel wire ropes 1 are both wound into a ring shape, and the connecting piece also includes a connecting buckle 10 connected at the ring-shaped part. In the solution, the connecting buckle 10 adopts the way of a U-shaped lock buckle, which is convenient for fixing and disassembling. Correspondingly, a connection hole is opened at the upper end of the sliding plate 7, and the upper end of the sliding plate 7 is connected through the connecting buckle 10 passing through the connection hole. The connecting buckle 10 connects the sliding plate 7 with the steel wire rope 2. And a groove 8 is opened at the bottom of the sliding plate 7, and the groove 8 penetrates through the sliding plate 7. A limiting plate 9 in contact with the bottom of the U-shaped steel channel 2 is penetrated in the groove 8, that is, the limiting plate 9 passes through the groove 8 at the bottom of the sliding plate 7 and can be fixed by forms such as welding.

[0030] Moreover, it should be noted that in order to adjust the position of the sliding plate 7 and be able to fix it at multiple positions along the length direction of the U-shaped steel channel 2, a plurality of threaded holes 15 are evenly opened on the side surface of the U-shaped steel channel 2, and the sliding plate 7 is fixed to the U-shaped steel channel 2 through a locking bolt 16.

[0031] In this embodiment, which is also one of the main design points of this solution, in combination with Figure 3 , two groups of mounting frames 3 are slidably connected between the two U-shaped steel channels 2 and can be fixed to the U-shaped steel channel 2 at multiple positions along the sliding direction, which is the same as the fixing method of the sliding plate 7. The mounting frame 3 is fixed to the U-shaped steel channel 2 by the locking bolt 16 passing through the threaded hole 15, and it can be fixed to different threaded holes 15 according to the length of the plate to be hoisted, thereby facilitating the hoisting of plates with different lengths.

[0032] On the basis of the above structure, two first connecting rods 4 extending in a separating direction are hinged to the bottom of the mounting bracket 3, that is, the two first connecting rods 4 extend away from the U-shaped channel steel 2, and the ends of the two first connecting rods 4 are both hinged with second connecting rods 5 extending in a converging direction, that is, the two second connecting rods 5 extend towards the direction close to the U-shaped channel steel 2. After extension, the two second connecting rods 5 form an intersection position where they are hinged. The two first connecting rods 4 and the two second connecting rods 5 form a shear structure. At the ends of the two second connecting rods 5, L-shaped clamping plates 6 are fixedly connected. The L-shaped clamping plates 6 and the second connecting rods 5 are integrally formed. The openings of the two L-shaped clamping plates 6 are arranged oppositely, that is, the openings of the two L-shaped clamping plates 6 both face the side of the U-shaped channel steel 2, forming the form of clamping jaws. When clamping a plate, place the plate between the two L-shaped clamping plates 6. The self-weight of the plate can make the L-shaped clamping plates 6 move towards each other to clamp the plate. And in order to lock the two L-shaped plates, a hook 12 is hinged to the hinged end of one of the second connecting rods 5, and a hanging rod 13 adapted to the hook 12 is arranged at the end of the other second connecting rod 5. After the two L-shaped clamping plates 6 clamp the plate, the hook 12 and the hanging rod 13 are matched to achieve the effect of fixing the two second connecting rods 5.

[0033] Moreover, an L-shaped supporting pad 11 is detachably connected to the inner side of the L-shaped clamping plate 6, and the width of the L-shaped supporting pad is greater than the width of the L-shaped clamping plate 6. The L-shaped supporting pad and the L-shaped clamping plate 6 can be detachably connected by bolts or the like. Through the setting of the L-shaped supporting pad, the contact area with the plate can be increased, and the stability of the plate fixation can be improved. And the L-shaped clamping plate 6 is inclined relative to the second connecting rod 5, and the inclination angle between the two is 110° - 150°. When the self-weight of the plate acts on the L-shaped clamping plate 6 downward, the bottom end of the L-shaped clamping plate 6 can at least move to a horizontal state, so that the L-shaped supporting pad can play a role in supporting the plate.

[0034] On the basis of the above structure, in order to limit the two ends of the hoisted plate or rod-shaped material and improve the safety performance of hoisting, L-shaped baffles 14 are connected to the opposite sides of the two mounting brackets 3, and their vertical ends extend downward. Moreover, the L-shaped baffles 14 can be fixed to the mounting brackets 3, and the components for installation and use are relatively simple. They can also be hinged to the mounting brackets 3 and can rotate upward around the hinge point. However, a damper or a locking member needs to be designed at the hinge position to prevent the plate from pushing the L-shaped baffle 14 to move. Such a design is convenient for taking out the plate on both sides. But for the fixed design, the cooperation between the hook 12 and the hanging rod 13 can also be opened, and then the two second connecting rods 5 are rotated outward, and then the L-shaped clamping plates 6 are driven to move outward to take out the plate.

[0035] Moreover, the width of the L-shaped baffle 14 is not greater than the distance between the two U-shaped steel channels 2, which facilitates the movement of the L-shaped baffle 14 between the two U-shaped steel channels 2 when adjusting the position of the mounting frame 3, and cooperates with the moving mounting frame 3 to limit the plates with different length dimensions.
