Description

Technical Field

[0001] The present invention relates to the technical field of traction devices, and in particular to a traction wheel with a lifting function. Background Art

[0002] At present, some steering wheel mechanisms with omnidirectional movement are widely used in the AGV industry. They can move omnidirectionally in factories or on good outdoor roads. However, some faults are inevitable during use. For example, if the walking wheel group fails and cannot move, the vehicle will stop in place and need to be moved with the help of lifting or other tools. Especially outdoors, when lifting is inconvenient, it can only be moved after the fault is eliminated, which seriously affects work. Summary of the Invention

[0003] The purpose of the present invention is to provide a traction wheel with a lifting function in order to solve the above problems.

[0004] The top of the guide sleeve is fixedly provided with a guide wheel, and the bottom of the guide sleeve is fixedly connected with the top surface of the base, and the guide wheel is fixedly provided with a guide wheel on the base.

[0005] Furthermore, the travel wheel is connected to the pad via bolts.

[0006] Furthermore, the pad is connected to the guide sleeve via screws.

[0007] Furthermore, the ball socket is a copper sleeve made of metal copper.

[0008] Furthermore, the gland is connected to the backing plate via screws.

[0009] Furthermore, the key is fixed to the inner wall of the guide sleeve by screws.

[0010] Furthermore, a handwheel is fixedly connected to the top of the trapezoidal screw.

[0011] The beneficial effects of the present invention are as follows: by installing a liftable traction wheel on the side of the AGV vehicle frame, when the AGV steering wheel fails, the entire vehicle can be lifted up by lifting the traction wheel, and the equipment can be towed to the designated location manually or by a tractor. When the AGV steering wheel is not faulty, it can be retracted without affecting normal walking. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0017] Example 1

[0018] like Figure 1-3 As shown, the present invention provides a traction wheel with a lifting function, including a connecting seat 3 installed on a vehicle frame, a trapezoidal screw rod 1 and a walking wheel 5 are respectively provided on the top and bottom of the connecting seat 3, a pad 10 is fixedly connected to the top surface of the walking wheel 5, a cylindrical pit is provided on the pad 10, a ball socket 12 with an interference fit is installed in the cylindrical pit, a ball head is fixedly connected to the bottom of the trapezoidal screw rod 1, and after the bottom of the trapezoidal screw rod 1 passes through the connecting seat 3, the ball head is locked into the ball socket 12 through a pressure cover 11, and the pressure cover 11 and the pad are fixedly connected. 10 is fixedly connected, a locking nut 2 is sleeved on the top of the trapezoidal screw rod 1, and the locking nut 2 is in contact with the top surface of the connecting seat 3, and a trapezoidal nut 7 in the form of a flange is sleeved on the bottom of the trapezoidal screw rod 1, and the trapezoidal nut 7 is connected to the trapezoidal screw rod 1 through a trapezoidal thread, and the top of the trapezoidal nut 7 is fixedly connected to the bottom surface of the connecting seat 3, and a guide sleeve 4 is sleeved on the trapezoidal nut 7, and the bottom of the guide sleeve 4 is fixedly connected to the top surface of the pad 10, and a keyway is provided between the mating surfaces of the trapezoidal nut 7 and the guide sleeve 4, and a key 9 is fixedly installed in the keyway.

[0019] In this embodiment, the travel wheel 5 is connected to the pad 10 by bolts.

[0020] In this embodiment, the backing plate 10 is connected to the guide sleeve 4 via screws 8 .

[0021] In this embodiment, the ball socket 12 is a copper sleeve made of metal copper.

[0022] In this embodiment, the gland 11 and the backing plate 10 are connected by screws 8 .

[0023] In this embodiment, the key 9 is fixed to the inner wall of the guide sleeve 4 by means of screws 8 .

[0024] In this embodiment, a handwheel 6 is fixedly connected to the top of the trapezoidal screw rod 1 .

[0025] The working principle of the present invention is as follows: when the AGV vehicle has a walking failure, first loosen the locking nut 2, manually rotate the handwheel 6, drive the trapezoidal screw 1 to rotate, and under the action of the trapezoidal thread, the trapezoidal screw 1 drives the guide sleeve 4 to slide up and down, thereby driving the walking wheel 5 to move up and down. Under the restriction of key 9, the guide sleeve 4 will not rotate. When the walking wheel 5 moves downward, the entire AGV vehicle frame can be lifted to make the AGV power wheel off the ground. After confirming that the AGV power wheel is off the ground, lock the locking nut 2, and then tow the vehicle away by manpower or a tractor.

[0026] The beneficial effects of the present invention are as follows: by installing a liftable traction wheel on the side of the AGV vehicle frame, when the AGV steering wheel fails, the entire vehicle can be lifted up by lifting the traction wheel, and the equipment can be towed to the designated location manually or by a tractor. When the AGV steering wheel is not faulty, it can be retracted without affecting normal walking.

[0027] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
