Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a flippable manually driven clamping sling device. Background Art

[0002] Jib cranes are industrial components and lightweight cranes that play a vital role in modern production and construction. When working near densely populated production lines, truck cranes require a lifting permit due to site constraints, resulting in significant wasted man-hours. Tower cranes, on the other hand, intrude into the production lines.

[0003] The existing technology, CN202322196142.7, is a mold-lifting and flipping robot, which is used in conjunction with a crane. There is a product that has no clamping parts on both sides, and due to its hollow structure and its special processing position, it cannot clamp the outside. Therefore, ordinary robots cannot clamp it, and it requires at least two processes to complete the processing, which is inefficient.

[0004] Therefore, it is necessary to design a reversible manually driven clamping sling device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a reversible manually driven clamping spreader device to overcome the above-mentioned shortcomings of the current prior art.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The swivel jaw assembly includes a swivel shaft seat provided on one side of the inner frame cross beam, a swivel jaw rotatably mounted on the swivel shaft seat through an shaft; a positioning mounting plate is provided on the inner frame and placed at the clamping end of the swivel jaw, and a positioning foot block is mounted on the positioning mounting plate. The swivel jaw driving assembly includes a bearing seat adjustment seat respectively provided at two ends of the inner frame, a bearing seat mounted on the bearing seat adjustment seat, a rotating shaft mounted in cooperation with the bearing seats at both ends through bearings, and a movable nut block at both ends of the rotating shaft is respectively mounted through a threaded connection.

[0008] Preferably, a fixed latch block is provided on the outer frame, and a latch for cooperating with the fixed latch block for fixing is provided on the inner frame.

[0009] Preferably, the positioning foot block is fixed to the positioning mounting plate by a nut.

[0010] Preferably, a mounting groove is provided at one end of the rotary clamping jaw, and one end of the mounting groove of the rotary clamping jaw is fixed to the movable nut block through a fixing member.

[0011] Preferably, a hand wheel or a driving unit for driving the rotating shaft to rotate is provided in the middle position of the rotating shaft.

[0012] The beneficial effects of the present invention are as follows: the present technical solution realizes the flipping function by setting up two groups of staggered frames and cooperating with the installation, and a clamping assembly is set on the built-in frame, and a group of rotary clamping jaw driving assemblies simultaneously drive the rotary clamping jaw assemblies at both ends to clamp, thereby achieving clamping of the inner side of the product without affecting the outer side of the product, and cooperating with other equipment for processing, thereby improving efficiency.

[0019] Reference Figures 1 to 3 A reversible manually driven clamping and lifting device comprises an outer frame 1 capable of being connected with a lifting mechanism, an inner frame 3 rotatably mounted on the outer frame via a bearing 2, and a clamping assembly 4 provided on the inner frame for clamping a product;

[0020] In order to fix the angle of the inner frame 3 after flipping and to ensure that it does not rotate when clamped, a fixed latch block 5 is provided on the outer frame 1, and a latch 6 for cooperating with the fixed latch block 5 for fixing is provided on the inner frame;

[0021] The clamping assembly 4 includes a rotary clamping jaw assembly 41 provided at both ends of the inner frame 3, and a rotary clamping jaw driving assembly 42 for simultaneously driving the rotary clamping jaw assemblies at both ends to clamp or release;

[0022] The swivel clamp assembly 41 includes a swivel shaft seat 411 provided on one side of the inner frame crossbeam, and a swivel clamp 413 rotatably mounted on the swivel shaft seat via a shaft 412; a positioning mounting plate 414 is provided on the inner frame and at the clamping end of the swivel clamp 413, and a positioning foot block 415 is mounted on the positioning mounting plate. The positioning foot block 415 is fixed to the positioning mounting plate 414 by a nut, and the position of the foot block 415 mounted on the positioning mounting plate 414 can be adjusted according to the positioning position of the product, thereby adapting to different models of products for limited installation;

[0023] The rotary jaw drive assembly 42 includes bearing seat adjustment seats 421 respectively provided at both ends of the inner frame, bearing seats 422 mounted on the bearing seat adjustment seats, a rotating shaft 424 respectively mounted on the bearing seats at both ends through bearings 423, and movable nut blocks 425 respectively mounted on both ends of the rotating shaft through threaded connections;

[0024] In order to fix the rotating clamping jaw and the moving nut block, a mounting groove is formed at one end of the rotating clamping jaw 413, and one end of the mounting groove of the rotating clamping jaw 413 is fixed to the moving nut block 425 through a fixing member 426;

[0025] A hand wheel 7 or a driving unit for driving the rotating shaft 424 is provided in the middle of the rotating shaft 424. Manually turning the hand wheel 7 drives the rotating shaft 424 to rotate. Since the rotating shaft and the movable nut block 425 are threadedly connected, and since the rotating shaft does not move, the movable nut block 425 moves horizontally along the rotating shaft during the rotation process, thereby driving the rotating jaw 413 to move. Since the rotating jaw is rotatably mounted on the rotating shaft seat through the shaft 412, it is flipped around the shaft 412 as the center point, thereby achieving the clamping and loosening of the rotating jaw.

[0026] In this embodiment, the position where the product needs to be positioned is set corresponding to the positioning foot block 415, and the positioning foot block 415 is used for limiting the position. At the same time, the hand wheel 7 is manually turned to drive the rotating shaft to rotate, thereby moving the movable nut blocks 425 at both ends, thereby driving the rotary clamp to flip and clamp the product. The pin 6 is pulled out and the inner frame can be manually flipped to drive the product to flip and adjust the angle for processing.

[0027] The benefits of the present invention are that the technical solution realizes the flipping function by setting up two sets of staggered frames and cooperating with the installation, and a clamping assembly is set on the built-in frame. A set of rotary clamping jaw driving assemblies simultaneously drives the rotary clamping jaw assemblies at both ends to clamp, thereby clamping the inner side of the product without affecting the outer side of the product, and cooperating with other equipment for processing, thereby improving efficiency.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
