Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a hoisting device for bar processing. Background Art

[0002] Rod is a solid plastic continuous profile with a regular shape, usually with a cross-section of a circle, rectangle, regular polygon, triangle and ellipse. The definition of a rod refers to a solid plastic or metal material with a cross-section of the above shapes. Common materials include PVC (polyvinyl chloride) and stainless steel, which are widely used in industry, construction, agriculture, daily life, packaging, electricity and other fields. Stainless steel bars are often used in high-rise building foundations and highway isolation nets in cold regions due to their excellent corrosion resistance and high strength.

[0003] When hoisting rods, multiple rods need to be bundled together and then hoisted and transported using a hoisting device. However, when multiple rods are bundled together, it is easy for the multiple rods to squeeze each other, so that some plastic rods may be damaged. In addition, the bundled rods are not tight enough, and there are gaps between adjacent rods, which may cause the hidden danger of falling off during the hoisting process. Therefore, a hoisting device for rod processing is proposed. Utility Model Content

[0027] Example

[0028] Reference Figure 1-Figure 4 , which is an embodiment of the present utility model, provides a hoisting device for bar processing, comprising: a hoisting unit 100 and a limiting unit 200;

[0029] The hoisting unit 100 includes a hoisting platform 101 and a vertical plate 102 fixedly mounted on the top of the hoisting platform 101. An electric slide rail 103 is fixedly mounted on one side of the vertical plate 102. An electric telescopic rod 104 is fixedly connected to the bottom of the output end of the electric slide rail 103.

[0030] The limiting unit 200 includes a door-shaped plate 201 fixedly connected to the bottom of the output end of the electric telescopic rod 104, the inner wall of the door-shaped plate 201 is rotatably connected to a rotating rod 202, the rod surface of the rotating rod 202 is slidably sleeved with two symmetrically distributed discs 203, the rod surface of the rotating rod 202 is fixedly sleeved with a limiting disk 204, the side wall of the limiting disk 204 is provided with a plurality of evenly distributed U-shaped grooves 205, and a limiting groove 206 is provided on one side of the inner wall of each U-shaped groove 205. The inner wall of each limiting groove 206 is rotatably connected to a round rod 207, and the rod surface of each round rod 207 is fixedly sleeved with a baffle 208. A torsion spring 209 sleeved on the round rod 207 is fixedly connected between each baffle 208 and the limiting groove 206. The limiting unit 200 also includes a limiting assembly 210 for limiting the baffle 208.

[0031] Among them, the limiting assembly 210 includes multiple sleeves 2101 fixedly connected to one side of the limiting disk 204, and the inner cavity of each sleeve 2101 is slidably provided with a pin 2102 that passes through the limiting disk 204. Each pin 2102 is in contact with the corresponding baffle 208, and a spring 2103 mounted on the sleeve 2101 is fixedly connected between each pin 2102 and the limiting disk 204.

[0032] The electric slide rail 103 is used to drive the electric telescopic rod 104 to move horizontally, and the electric telescopic rod 104 is used to drive the door-shaped plate 201 to move up and down, so that the rods can be hoisted and transferred to racks or trucks at different heights for subsequent production and processing. The limit plate 204 and the U-shaped groove 205 are used to install the rods. When installing, the rods are aligned with the U-shaped groove 205 near the top of the limit plate 204 from top to bottom, and the rods squeeze the baffle 208 to the limit plate 204. In the groove 206, the baffle 208 can be deflected by the round rod 207. When the baffle 208 is fully deflected into the limiting groove 206, the baffle 208 no longer blocks the U-shaped groove 205. At this time, the bar moves to the position of the U-shaped groove 205 close to the center of the limiting plate 204 under the action of its own gravity. At this time, the bar does not contact the baffle 208. Then the torsion spring 209 drives the baffle 208 to deflect and return to its original position, so that the baffle 208 blocks the U-shaped groove 205.

[0033] When the baffle 208 is reset, the baffle 208 will contact the latch 2102, and then the limit plate 204 is rotated and the above operation is repeated to place the rod in each U-shaped groove 205 in turn. When the U-shaped groove 205 is rotated to an inverted U shape, the rod falls under the action of gravity and contacts the baffle 208. The baffle 208 is blocked by the latch 2102 so that the baffle 208 will not deflect, thereby limiting the rod in the U-shaped groove 205 and preventing the rod from falling off. The diameter of the disc 203 is the same as that of the limit plate 204. The disc 203 can limit the two ends of the rod so that it will not slip off from the two sides of the U-shaped groove 205, thereby ensuring that multiple rods will not be squeezed and deformed during the lifting process, and the rods will not fall off in the air. Subsequently, the electric slide rail 103 and the electric telescopic rod 104 are used to lift the rod.

[0034] One end of the latch 2102 is located in the limiting groove 206 and will not block the rod. When taking out the rod, the latch 2102 at the bottom is pulled so that the latch 2102 slides in the sleeve 2101 and no longer contacts the baffle 208. At this time, the rod presses the baffle 208 downward by its own gravity, and the baffle 208 is deflected away from the U-shaped groove 205 by the pressure, so that the rod can automatically detach from the U-shaped groove 205. After detachment, the torsion spring 209 drives the baffle 208 to automatically deflect and reset, then releases the latch 2102, and the spring 2103 pulls the latch 2102 toward the baffle 208, so that the latch 2102 contacts the baffle 208 again to facilitate the next installation of the rod, and then deflects the limit plate 204 to rotate each latch 2102 to the bottom of the limit plate 204, and pulls each latch 2102 in turn to quickly remove each rod from the limit plate 204.

[0035] In addition, one side of each latch 2102 is fixedly connected to a T-rod 211, the outer wall of the rotating rod 202 is slidably sleeved on the limit plate 212, each T-rod 211 slides through the limit plate 212, one side of the limit plate 212 is fixedly connected to a fixing plate 213, and one side of the fixing plate 213 is threadedly connected to a threaded rod 214 that passes through the fixing plate 213.

[0036] By pulling the limit plate 212 away from the limit plate 204, the limit plate 212 can drive all the latches 2102 to move away from the limit plate 204 through the T-bar 211, thereby releasing the restriction of all the baffles 208 on the U-shaped groove 205 and facilitating the rapid removal of the rod from the U-shaped groove 205. When the limit plate 212 is released, all the springs 2103 will simultaneously pull all the latches 2102 toward the baffles 208 to complete the automatic reset.

[0037] By rotating the threaded rod 214 so that it is against the limit plate 204, the threaded rod 214 can drive the limit plate 212 to move away from the limit plate 204, and make its multiple pins 2102 no longer contact with the baffle 208. Then the worker can rotate the limit plate 204 one circle to quickly remove all the rods from the U-shaped groove 205 for the worker's use. After removal, the threaded rod 214 is rotated in the opposite direction so that it no longer contacts the limit plate 204, so that the pins 2102 can automatically reset.

[0038] Furthermore, both sides of the door-shaped plate 201 are threadedly connected with adjustment rods 215 that penetrate the door-shaped plate 201 , and the two adjustment rods 215 are rotatably connected to the two disks 203 respectively.

[0039] The distance between the two discs 203 can be adjusted by rotating the two adjusting rods 215 , so that the two discs 203 can block both ends of bars of different lengths to prevent the bars from sliding off the two sides of the U-shaped groove 205 .

[0040] Furthermore, two symmetrically distributed reinforcement plates 105 are fixedly connected to the side walls of the vertical plate 102 and the electric slide rail 103, and two pairs of universal wheels 106 are rotatably connected to the bottom of the lifting platform 101.

[0041] The two reinforcing plates 105 make the reinforcing plates 105, the vertical plate 102 and the electric slide rail 103 form a triangular structure, thereby improving the supporting strength of the vertical plate 102 and the stability of the movement of the electric slide rail 103. The universal wheels 106 make it easier for workers to move the lifting platform 101, thereby facilitating the lifting of the rods.

[0042] During use, when hoisting the rod, the hoisting platform 101 is moved to the specified position by the universal wheel 106, and then the rod is aligned with the U-shaped groove 205 near the top of the limit plate 204, and the baffle 208 is squeezed into the limit groove 206 by the rod. When the rod is no longer in contact with the baffle 208, the torsion spring 209 drives the baffle 208 to deflect and reset, so that the baffle 208 blocks the U-shaped groove 205. Then, the limit plate 204 is rotated and the above operation is repeated to place the rod in each U-shaped groove 205 in turn, and then the two adjusting rods 215 are rotated to make the two discs 203 block the two ends of the rod to prevent the rod from sliding from both sides of the U-shaped groove 205. Then, the electric slide rail 103 and the electric telescopic rod 104 are used to move and hoist the rod;

[0043] When taking out the rods, the threaded rod 214 is rotated to make it contact with the limit plate 204, thereby driving the limit plate 212 to move away from the limit plate 204 through the threaded rod 214, and making its multiple pins 2102 no longer contact with the baffle 208. Then the worker rotates the limit plate 204 one circle. During the rotation, the rods can automatically disengage from the U-shaped groove 205 due to their own weight, thereby all the rods can be quickly taken out of the U-shaped groove 205. After taking them out, the threaded rod 214 is rotated in the opposite direction so that it no longer contacts with the limit plate 204, so that the pins 2102 can automatically reset.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
