Description

Technical Field

[0001] The invention relates to a detachable cable reel. Background Art

[0002] A crane (also known as a traveling crane), especially a heavy-loaded crane that travels long distances, requires a reel to be installed at the base. The purpose of the reel is to reel in the cables that supply power to the crane and for communications.

[0003] In the traditional technical solution, the reel used is controlled by a motor to reel in. Since the weight of the cable after winding is very large, it needs to be used with an additional reducer, which results in high equipment costs and low energy utilization, requiring additional electricity. In addition, the part of this type of reel that wraps the cable is not detachable, so it is not very convenient in use and subsequent cable maintenance.

[0004] Secondly, the cable is reeled in by means of a motor in conjunction with a reducer. The speed of the motor will affect the actual number of revolutions of the reel, which may cause the cable to be pulled or the cable to be loosely wound, resulting in the cable being stuck in the roller.

[0005] To this end, we designed a detachable cable reel that can be disassembled and assembled, and can be driven by the movement of the crane to achieve cable winding or loosening. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a detachable cable reel which can be assembled and disassembled and can be driven by the movement of a crane to realize cable winding or loosening.

[0007] To solve the above problems, the present invention adopts the following technical solutions:

[0008] A detachable cable reel comprises a reel and a rotating support device installed on a traveling crane base. The reel and the rotating support device are installed in a quick-detachable manner. A transmission wheel is installed inside the traveling crane base. A transmission unit is cooperated between the transmission wheel and the rotating support device. When the traveling crane moves along a track, the transmission wheel rotates after contacting the track. The rotation of the transmission wheel drives the reel to rotate via the transmission unit.

[0009] Preferably, the reel includes a core shaft, baffles are provided at both ends of the core shaft, the cable is wound between the baffles on both sides and wrapped around the core shaft, an axial tube is provided at the axis center of the core shaft, a width plate is provided between the axial tube and the core shaft, a connecting disk is provided at one end of the axial tube, and the cable is detachably connected to the rotating support device through the connecting disk.

[0010] Preferably, the rotating support device includes a bearing seat, and a rotating shaft is rotatably engaged at the axis center of the bearing seat. A connecting seat is provided below the bearing seat, and the connecting seat is fixedly connected to the crane base. One end of the rotating shaft cooperates with the transmission unit, and the other end is provided with a disk seat. The connecting disk is inserted into the disk seat and locked.

[0011] Preferably, an annular card groove is provided on the outer wall of the connecting disk, a locking groove is provided in an annular manner at the bottom of the card groove, and a plurality of slots are provided in an annular manner on the outer wall of the disk seat, the slot 210 corresponds to the card groove, a stopper is provided in the slot, a locking plate is fitted through the slot, a vertical slide groove is provided in the middle of the locking plate, the stopper is fitted in the slide groove, the upper and lower ends of the slide groove are closed, a concave hole is provided at the end of the stopper facing the axis of the disk seat, a spring is fitted in the concave hole, the spring acts on the groove wall of the slide groove, under the action of the spring, the locking plate slides toward the axis of the disk seat, and is inserted into the card groove after sliding, and an insert plate is provided at the bottom of the locking plate, and the insert plate is inserted into the lock groove.

[0012] Preferably, the end of the connecting disk inserted into the disk seat is processed with a conical guide surface, and the plug plate has a passive guide surface that matches the conical guide surface. Under normal circumstances, the locking plate moves toward the axis of the disk seat to the limit position. During the process of inserting the connecting disk into the disk seat, the conical guide surface acts on the passive guide surface, so that the locking plate passively moves outward until the locking plate corresponds to the slot and then rebounds under the action of the spring and is inserted into the slot.

[0013] Preferably, the transmission unit comprises a driving wheel connected to the transmission wheel, and a driven wheel connected to the rotating shaft, and a transmission belt is provided between the driving wheel and the driven wheel.

[0014] Preferably, the transmission belt is a synchronous toothed belt.

[0015] Preferably, the connecting seat is cooperated with a tensioner, and the tensioner is supported on the inner side of the transmission belt.

[0016] Preferably, the tensioner includes a connecting plate connected to the connecting seat, on which are arranged more than two bolts, a tensioning shaft is fitted between the more than two bolts, an outer limit nut is provided on the bolt, and the outer limit nut limits the outward movement of the tensioning shaft, an inner limit nut is fitted on the bolt, a first spring is sleeved on the bolt, the first spring acts between the inner limit nut and the tensioning shaft, a tensioning wheel is fitted through the tensioning shaft, and the tensioning wheel is supported on the inner side of the transmission belt.

[0017] Preferably, a tire bead is provided on the outside of the driving wheel, and the tire bead is squeezed and deformed after contacting the crane track, and the surface of the tire bead is processed with anti-skid patterns.

[0018] The beneficial effects of the present invention are:

[0019] Advantage 1: This device does not need to adopt an external power structure. When it moves by relying on a crane, the friction force is generated by the contact between the transmission wheel and the track, which drives the drum to rotate forward and reverse to achieve cable winding.

[0020] The second advantage is that the reel can be disassembled individually, making it easy to replace the cable as a whole.

[0021] Advantage three: the reel adopts quick-release installation method, which is convenient for disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

The reel 1 and the rotating support device 2 are quickly detachably installed, a transmission wheel 3 is installed inside the traveling crane base, and a transmission unit 4 is cooperated between the transmission wheel 3 and the rotating support device 2. When the traveling crane moves along a track, the transmission wheel 3 rotates after contacting the track, and the rotation of the transmission wheel 3 drives the reel 1 to rotate via the transmission unit 4.

[0035] In the above technical solution, the movement of the crane drives the transmission wheel 3 to rotate after friction with the track, so that the cable can be wound or loosened during the movement of the crane, and the drum will only move when the crane moves, avoiding excessive tension of the cable.

[0036] According to the traveling speed of the crane, a transmission unit 4 with a suitable transmission ratio is selected so that the winding speed of the cable matches the traveling speed of the crane.

[0037] See also Figure 2 and Figure 3As shown, the reel 1 includes a core shaft 101, baffles 102 are provided at both ends of the core shaft 101, the cable is rolled up between the baffles 102 on both sides and wound around the core shaft 101, an axial tube 103 is provided at the axis center of the core shaft 101, a web 104 is provided between the axial tube 103 and the core shaft 101, a connecting disk 105 is provided at one end of the axial tube 103, and the cable is detachably connected to the rotating support device 2 through the connecting disk 105.

Under normal circumstances, the locking piece 212 moves toward the axis of the disk seat 24 to the limit position.
