Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a hoisting device for civil engineering. Background Technology

[0002] With societal development, the types of auxiliary equipment used in the construction industry are increasing, greatly enhancing construction efficiency. Lifting devices are particularly common, used to transport building materials to higher locations. In civil engineering, lifting devices are frequently used to lift and install heavy pipes.

[0003] According to Chinese Patent Application No. CN202320882040.8, a hoisting device for civil engineering includes a left linkage plate, a left clamping seat, a first moving plate, a rotating rod, and a left compression spring. The rotating rod is located on the lower side inside the hoisting seat, and the first moving plate is located on the left side inside the hoisting seat. The left linkage plate is welded to the lower end face of the first moving plate. Left compression rods are symmetrically inserted on the upper, lower, front, and rear sides inside the left linkage plate. Left compression springs are symmetrically embedded on the upper, lower, front, and rear sides inside the left linkage plate. The left clamping seat is welded to the right end face of the left linkage plate. In this invention, when the rotating plate is rotated clockwise, the rotating rod rotates along with it. Simultaneously, the left linkage plate moves the left clamping seat to the right, while the right linkage plate moves the right clamping seat to the left, so that the left and right clamping seats can clamp external pipes.

[0004] However, the above-mentioned equipment still has some shortcomings. For example, during the hoisting and lifting of steel pipes, the weight of the steel pipes will act on the rotating rod, causing the rotating rod to be under high load for a long time, which is prone to bending, wear or even breakage. This not only shortens the service life of the device, but also poses safety hazards. To solve the above problems, we propose a hoisting device for civil engineering. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hoisting device for civil engineering, solving the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A hoisting device for civil engineering includes: a shell, a top plate fixedly installed on the top surface of the shell, four hooks fixedly installed on the top surface of the top plate, and two clamping plates provided on the bottom surface of the shell; and a clamping assembly disposed on the bottom surface of the shell for clamping goods.

[0008] By adopting the above technical solution, a hook is set up to connect to the crane for subsequent hoisting and lifting.

[0009] Preferably, the clamping assembly includes: two bottom holes, both of which are formed on the bottom surface of the housing; two inner pillars are provided inside the bottom holes; the inner pillars are fixedly connected to the adjacent clamping plates; support grooves are respectively formed on the left and right sides of the housing; a support frame is provided between the two support grooves; and the support frame is fixedly connected to the adjacent inner pillars.

[0010] By adopting the above technical solution and setting up support frames, the two support frames can be pushed during use to move the two clamping plates, thereby achieving the effect of clamping the goods.

[0011] Preferably, the clamping assembly further includes: two side holes, which are respectively opened on the left and right sides of the housing; bearings are fixedly installed inside the side holes; a bidirectional lead screw is fixedly installed between the two bearings; a lead screw nut is fixedly installed on the top surface of the support frame; the lead screw nut is connected to the bidirectional lead screw; two top holes are opened on the top surface of the lead screw nut; two connecting rods are fixedly installed on the top surface of the support frame; and the connecting rods are sleeved together with the adjacent top holes.

[0012] By adopting the above technical solution and setting a bidirectional lead screw, the two support frames can be moved closer or further apart synchronously by rotating the bidirectional lead screw and the action of the lead screw nut, thereby clamping the goods. At the same time, since the support frame is supported by the support groove, the movement of the lead screw nut will act on the support frame through the sleeved connecting rod. Therefore, the bidirectional lead screw will not bear the weight of the goods, thereby increasing the service life of the equipment.

[0013] Preferably, the clamping assembly further includes a movable rod, which is fixedly installed inside the support groove, and two connecting holes are provided on one side of the support frame, the connecting holes being sleeved with the movable rod.

[0014] By adopting the above technical solution, a movable rod is set up to provide guidance for the support frame and the connecting hole sleeve.

[0015] Preferably, the outer wall of the movable rod has two sliding grooves, and the inner wall of the connecting hole has two locking blocks fixedly installed. The locking blocks are sleeved together with the sliding grooves, and one side of the locking blocks has several circular grooves, with ball bearings rollingly connected inside the circular grooves.

[0016] By adopting the above technical solution and setting ball bearings to fit the slide groove, the smoothness of the support frame movement is increased.

[0017] Preferably, an arc-shaped frame is fixedly installed on one side of the clamping plate, and an anti-slip pad is fixedly installed on the inner wall of the arc-shaped frame.

[0018] By adopting the above technical solution, an arc-shaped frame is set up to work with an anti-slip mat to stably clamp the goods.

[0019] Preferably, a drive motor is fixedly installed on one side of the housing, and the output shaft of the drive motor is fixedly connected to the bidirectional lead screw.

[0020] By adopting the above technical solution, a drive motor is set up to drive the bidirectional lead screw to rotate, thereby adjusting the two arc-shaped frames to clamp the goods, increasing convenience.

[0021] In summary, the present invention has the following main advantages:

[0022] A hook is installed to connect to a crane for subsequent lifting. A double-acting screw is used; during operation, rotating the screw and its nut allows the two support frames to move synchronously closer or further apart, thus clamping the goods. Since the support frames are supported by support grooves, the movement of the screw nut is transmitted to the support frames via a connecting rod, meaning the double-acting screw does not bear the weight of the goods, increasing the equipment's lifespan. A movable rod guides the support frames through the connecting hole. Ball bearings ensure smooth movement of the support frames by conforming to the sliding groove. An arc-shaped frame, in conjunction with an anti-slip pad, provides stable clamping for the goods. Attached Figure Description

[0030] refer to Figures 1-4 A hoisting device for civil engineering includes: a housing 100, a top plate 200 fixedly installed on the top surface of the housing 100, four hooks 300 fixedly installed on the top surface of the top plate 200, two clamping plates 400 provided on the bottom surface of the housing 100, and a clamping assembly 500 provided on the bottom surface of the housing 100 for clamping goods. The hooks 300 are used to connect to a crane for subsequent hoisting. The clamping assembly 500 includes two bottom holes 501, both of which are formed in the housing 100. On the bottom surface of the housing 100, two inner columns 502 are provided inside the bottom hole 501. The inner columns 502 are fixedly connected to the adjacent clamping plate 400. Support grooves 503 are respectively opened on the left and right sides of the housing 100. A support frame 504 is provided between the two support grooves 503. The support frame 504 is fixedly connected to the adjacent inner columns 502. By setting the support frame 504, the two clamping plates 400 can be moved by pushing the two support frames 504 during use, thereby achieving the effect of clamping the goods.

[0031] refer to Figures 1-4The clamping assembly 500 further includes: two side holes 505, which are respectively opened on the left and right sides of the housing 100. Bearings 506 are fixedly installed inside the side holes 505. A bidirectional lead screw 507 is fixedly installed between the two bearings 506. A lead screw nut 508 is fixedly installed on the top surface of the support frame 504. The lead screw nut 508 is connected to the bidirectional lead screw 507. Two top holes 509 are opened on the top surface of the lead screw nut 508. Two connecting rods 510 are fixedly installed on the top surface of the support frame 504. The connecting rods 510 are sleeved with adjacent top holes 509. By setting the bidirectional lead screw 507, during use, the bidirectional lead screw 507 can be rotated to pass through the lead screw nut 507. The function of 8 is to enable the two support frames 504 to move closer or further apart synchronously, thereby clamping the goods. At the same time, since the support frame 504 is supported by the support groove 503, the movement of the lead screw nut 508 will act on the support frame 504 through the sleeved connecting rod 510. Therefore, the bidirectional lead screw 507 will not bear the weight of the goods, thereby increasing the service life of the equipment. The clamping assembly 500 also includes: a movable rod 511, which is fixedly installed inside the support groove 503. Two connecting holes 512 are opened on one side of the support frame 504. The connecting holes 512 are sleeved with the movable rod 511. By setting the movable rod 511, it is used to provide guidance for the support frame 504 when sleeved with the connecting holes 512.

[0032] refer to Figures 1-4 The outer wall of the movable rod 511 has two sliding grooves 600. The inner wall of the connecting hole 512 is fixedly installed with two locking blocks 601. The locking blocks 601 are sleeved together with the sliding grooves 600. A number of circular grooves 602 are opened on one side of the locking blocks 601. The circular grooves 602 are connected to rolling balls 603. By setting the balls 603, they are used to fit the sliding grooves 600, thereby increasing the smoothness of the support frame 504 when moving. An arc frame 700 is fixedly installed on one side of the clamping plate 400. An anti-slip pad 701 is fixedly installed on the inner wall of the arc frame 700. By setting the arc frame 700, it is used to cooperate with the anti-slip pad 701 to stably clamp the goods. A drive motor 800 is fixedly installed on one side of the housing 100. The output shaft of the drive motor 800 is fixedly connected to the bidirectional lead screw 507. By setting the drive motor 800, it is used to drive the bidirectional lead screw 507 to rotate, thereby adjusting the two arc frames 700 to clamp the goods, increasing convenience.

[0033] Working principle: Please refer to Figures 1-4As shown, during use, the crane can be connected via hook 300, and then the drive motor 800 is turned on to drive the bidirectional lead screw 507 to rotate. Through the action of the lead screw nut 508, the two support frames 504 can move closer or further apart synchronously. The arc frame 700, in conjunction with the anti-slip pad 701, provides stable clamping for the goods. Since the support frame 504 is supported by the support groove 503, the movement of the lead screw nut 508 will act on the support frame 504 through the sleeved connecting rod 510. Therefore, the bidirectional lead screw 507 will not bear the weight of the goods, thereby increasing the service life of the equipment. The movable rod 511 is used to provide guidance for the support frame 504 by sleeved with the connecting hole 512, and the ball bearing 603 is used to fit the sliding groove 600, thereby increasing the smoothness of the movement of the support frame 504.
