Description

Technical Field

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

[0002] The material lifting device is a small electric hoist. When using a traditional small electric hoist, due to its portable nature, it is usually not used in conjunction with a beam or guide rail. The top of the hoist is usually movably suspended on a support rod (equivalent to a beam that guides and limits the large electric hoist). This causes the material lifting device to easily shake relative to the support rod, causing the objects lifted by the material lifting device to shake, which poses a certain risk. Therefore, it is necessary to develop a structure that can reduce the shaking amplitude of the material lifting device relative to the support rod, thereby improving the safety of the use of the material lifting device. Utility Model Content

[0003] The utility model aims to provide a material lifting device, aiming to solve the problem that the material lifting device in the prior art is dangerous when in use.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a material lifting device, including an electric hoist body, a mounting plate is symmetrically arranged on the top of the electric hoist body, a driving cavity is arranged inside the mounting plate, a bidirectional screw is rotatably arranged inside the driving cavity, a driving member for driving the bidirectional screw to rotate is arranged outside the mounting plate, nut blocks are threadedly installed at the positive thread and negative thread of the bidirectional screw, an inverted T-shaped slide groove is arranged above the driving cavity, a T-shaped slider connected to the nut block is penetrated inside the inverted T-shaped slide groove, a clamping plate is arranged on the top of the T-shaped slider, a through groove is penetrated on one side of the clamping plate, a plate body is penetrated in the through groove of the two clamping plates, a threaded hole is penetrated on the top of the clamping plate, and a fastening bolt for fixing the plate body is arranged inside the threaded hole.

[0005] Preferably, the driving member is a motor arranged outside the mounting plate, and the output end of the motor passes through the interior of the driving cavity and is connected to the end of the bidirectional lead screw to drive the bidirectional lead screw to rotate inside the driving cavity.

[0006] Preferably, the clamping plate is located above the inverted T-shaped slide groove.

[0007] The beneficial effects of the utility model are:

[0008] When the utility model is in use, the support rod is located between the two clamping plates, and then the driving member is started, which drives the two-way screw rod to rotate, and the rotation of the two-way screw rod drives the nut block to move, and the movement of the nut block drives the T-shaped slider to move, and the movement of the T-shaped slider drives the clamping plates to clamp the support rod. After the clamping plates clamp the support rod, the plate body is inserted into the interior of the through groove, and then the tightening bolts are screwed to support the plate body, so that the support rod is limited and fixed, thereby reducing the shaking amplitude of the electric hoist body when hoisting objects, and improving the safety of the electric hoist body when in use.

[0014] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0015] like Figures 1 to 4 As shown, a material lifting device comprises an electric hoist body 1, a mounting plate 2 is symmetrically arranged on the top of the electric hoist body 1, a driving cavity 3 is arranged inside the mounting plate 2, a bidirectional screw rod 4 is rotatably arranged inside the driving cavity 3, a driving member 5 for driving the bidirectional screw rod 4 to rotate is arranged outside the mounting plate 2, a nut block 6 is threadedly installed at the positive thread and the negative thread of the bidirectional screw rod 4, an inverted T-shaped slide groove 7 is arranged above the driving cavity 3, a T-shaped slider 8 connected to the nut block 6 is penetrated inside the inverted T-shaped slide groove 7, a clamp plate 9 is arranged on the top of the T-shaped slider 8, a through groove 10 is penetrated on one side of the clamp plate 9, a plate body 11 is penetrated in the through groove 10 of the two clamp plates 9, a threaded hole 12 is penetrated on the top of the clamp plate 9, and a fastening bolt 13 for fixing the plate body 11 is arranged inside the threaded hole 12.

[0016] When the cam 8 is in the state of being moved, the two-way screw rod 4 is moved, and the two-way screw rod 4 is moved, so that the cam 8 can move freely, and the two-way screw rod 4 is moved freely, so that the cam 8 can move freely, and the two-way screw rod 4 is moved freely.

[0017] Specifically, the driving member 5 is a motor arranged outside the mounting plate 2 , and the output end of the motor passes through the interior of the driving cavity 3 and is connected to the end of the bidirectional screw rod 4 to drive the bidirectional screw rod 4 to rotate inside the driving cavity 3 .

[0018] Specifically, the clamping plate 9 is located above the inverted T-shaped sliding groove 7 .

[0019] Working principle: when in use, by making the support rod be located between the two clamping plates 9, then starting the driving member 5, the driving member 5 drives the two-way screw rod 4 to rotate, and the rotation of the two-way screw rod 4 drives the nut block 6 to move. While the nut block 6 moves, the T-shaped slider 8 cooperates with the inverted T-shaped slot 7 to limit and guide the nut block 6 to prevent the nut block 6 from rotating with the two-way screw rod 4. The cooperation between the inverted T-shaped slot 7 and the T-shaped slider 8 avoids the two-way screw rod 4 from being subjected to the tension applied by the electric hoist body 1, thereby improving the operating stability of the two-way screw rod 4. The movement of the nut block 6 drives the T-shaped slider 8 to move, and the movement of the T-shaped slider 8 drives the clamping plate 9 to clamp the support rod. After the clamping plate 9 clamps the support rod, the plate body 11 is inserted into the interior of the through slot 10, and then the fastening bolt 13 is tightened to make it support the plate body 11, so that the support rod is limited and fixed, thereby reducing the shaking amplitude of the electric hoist body 1 when hoisting objects, and improving the safety of the electric hoist body 1 when in use.
