Description

Technical Field

[0001] The utility model relates to the technical field of guide devices, in particular to a rear guide device for hooklift equipment. Background Art

[0002] Hooklift equipment is widely used in loading and unloading boxes and is often installed on various transport vehicles. It has the advantages of being able to easily load and unload boxes. The rear guide device is a key component of the hooklift equipment. When loading, the box guide rail first falls on the rear guide device, which straightens the skewed box.

[0003] The angle of the existing rear guide device is fixed. When the box is tilted, the angles of the box guide rail and the roller of the rear guide device are different, which causes a certain torque when the roller rotates, aggravating the wear of the roller shaft. It also causes the wear between the roller and the box guide rail to increase, reducing the service life of the rear guide device. The rear guide device needs to be replaced as a whole, which is more cumbersome. Utility Model Content

[0004] The utility model aims to provide a rear guide device for a hooklift device to solve the problems raised in the above background technology.

[0008] Furthermore, an arc groove is provided on the upper surface of the installation frame, and a No. 2 bolt is movably embedded and installed on the lower surface of the connection block. The No. 2 bolt passes through the connection block and the arc groove and is slidably connected to the arc groove.

[0009] Preferably, a thread groove is provided on the lower surface of the U-shaped seat, the No. 2 bolt is screwed and connected to the thread groove, and one end of the arc-shaped telescopic rod is fixedly connected to the installation frame.

[0010] Furthermore, the rotating rod is fixedly mounted on the upper surface of the fixing plate, an adjusting disk is symmetrically fixedly mounted on the outer surface of the rotating rod, and a limit plug plate is provided on the outer movable sleeve of the rotating rod.

[0011] Preferably, a plurality of adjustment holes are provided on both side surfaces of the installation frame, the limit plug plate passes through the adjustment disk and is movably connected to the adjustment holes, and a fixing ring is fixedly installed on the outer surface of the rotating rod.

[0012] Preferably: the inner surface of the fixing ring is rotatably connected with a bidirectional threaded sleeve, both ends of the bidirectional threaded sleeve are screwed together with screws, one end of the two screws are respectively fixedly connected to two limit plates, and the outer surface of the bidirectional threaded sleeve is fixedly installed with a hexagonal nut.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The No. 1 bolt and No. 2 bolt make the U-shaped seat easy to disassemble, so that the roller of the rear guide device can be quickly replaced, reducing the replacement cost.

[0015] 2. When the roller rotates to adapt to the angle of the box guide rail, the connecting block rotates synchronously with the U-shaped seat, squeezing or stretching the arc spring. When the box is vacated, the arc spring itself has an elastic force to pull the connecting block to reset, so that the box gradually moves to the same direction as the hook device. Therefore, when the box is skewed, the angle of the roller can be adjusted to the angle of the box guide rail by adjusting the component, so that the two are in the same direction, so as to avoid the different angles of the roller and the box guide rail causing increased wear when the roller rotates. At the same time, it also reduces the wear between the roller and the box guide rail, and increases the service life of the rear guide device.

[0016] 3. When installing the rear guide device, install the fixing plate to one part of the hooklift device through the fasteners, screw the hexagonal nut to rotate the bidirectional threaded sleeve through the screwing with the two screws, so that the screws move in two different directions, drive the limit plug plate to move, insert it through the adjusting disk into the adjusting hole at the corresponding position, adjust the installation angle of the roller, so that the rear guide device can be installed on planes at different angles.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5 In the embodiment of the utility model, a rear guide device of a hook arm equipment includes a mounting frame 1, an adjusting component 2 is fixedly provided inside the mounting frame 1, the adjusting component 2 includes a U-shaped seat 201 and a roller 203, the roller 203 is rotatably connected to the inner surface of the U-shaped seat 201, a threaded connecting sleeve 202 is movably embedded and installed on the inner lower surface of the U-shaped seat 201, an arc-shaped telescopic rod 206 is fixedly installed on the inner upper surface of the mounting frame 1, an arc-shaped telescopic rod 206 is movably sleeved on the outer side of the arc-shaped telescopic rod 206, a connecting block 208 is fixedly installed on one end of the arc-shaped telescopic rod 206, a flipping component 3 is movably provided inside the mounting frame 1, the flipping component 3 includes a fixed plate 301 and a rotating rod 302, the rotating rod 302 passes through the mounting frame 1, and is rotatably connected to the mounting frame 1.

[0025] Specifically, the adjusting component 2 drives the roller 203 to rotate so that it adapts to the angle of the box guide rail, and resets the roller 203 under the elastic force of the arc spring 207. The installation angle of the roller 203 is adjusted by the flipping component 3, so that the angle of the roller 203 can be adjusted.

[0026] Embodiment 1

[0027] like Figure 3 As shown, in this embodiment, a through hole 102 is opened on the upper surface of the installation frame 1, a threaded connection sleeve 202 passes through the through hole 102 and is rotatably connected to the through hole 102, and a No. 1 bolt 204 is screwed and connected to the lower end of the threaded connection sleeve 202.

[0028] In this embodiment, for the sake of clarity of description, the threaded connection sleeve 202 is taken as an example in which the threaded connection sleeve 202 passes through the through hole 102 and is rotatably connected to the through hole 102. Through the rotatable connection between the threaded connection sleeve 202 and the through hole 102, the U-shaped seat 201 can be rotated with the threaded connection sleeve 202 as the rotation axis. Through the No. 1 bolt 204 and the No. 2 bolt 205, the U-shaped seat 201 is easy to disassemble, thereby facilitating the rapid replacement of the roller 203 of the rear guide device and reducing the replacement cost.

[0029] like Figure 2-3 As shown, in this embodiment, an arc groove 103 is provided on the upper surface of the installation frame 1, and a No. 2 bolt 205 is movably embedded in the lower surface of the connecting block 208. The No. 2 bolt 205 passes through the connecting block 208 and the arc groove 103 and is slidably connected to the arc groove 103; a threaded groove 209 is provided on the lower surface of the U-shaped seat 201, and the No. 2 bolt 205 is screwed together with the threaded groove 209, and one end of the arc telescopic rod 206 is fixedly connected to the installation frame 1.

[0030] In specific implementation, when the roller 203 rotates to adapt to the angle of the box guide rail, the connecting block 208 rotates synchronously with the U-shaped seat 201, squeezing or stretching the arc spring 207. When the box is vacant, the arc spring 207 itself has an elastic force, pulling the connecting block 208 to reset, so that the box gradually moves to the same direction as the arm hook device. Therefore, by adjusting the component 2 when the box is tilted, the angle of the roller 203 is automatically adapted to the angle of the box guide rail, so that the two are in the same direction, so as to avoid the different angles of the roller 203 and the box guide rail causing the roller 203 to rotate. The wear is aggravated, and the wear between the roller 203 and the box guide rail is also reduced, thereby increasing the service life of the rear guide device.

[0034] In specific implementation, when installing the rear guide device, the fixing plate 301 is installed to a place of the arm hook device by fasteners, and the hexagonal nut 308 is screwed to rotate the bidirectional threaded sleeve 306 through the screwing with the two screw rods 307, so that the screw rods 307 move in two different directions, driving the limit plug plate 304 to move, and insert it through the adjustment disk 303 into the adjustment hole 101 at the corresponding position, and adjust the installation angle of the roller 203 so that the rear guide device can be installed on planes at different angles.
