Description

Technical Field

[0001] The utility model relates to the technical field of tower cranes, in particular to a tower crane cable storage and maintenance platform. Background Art

[0002] Tower cranes are also called tower cranes. Due to their large operating space, they are mainly used for vertical and horizontal transportation of materials in house construction and installation of building components. In order to control the movement of related devices on the boom, it is necessary to use cables to introduce power from the ground. The cables are usually hundreds of meters long and weigh hundreds of kilograms. When the tower crane is used, the cables need to be arranged smoothly and the whole cable needs to be coiled together, and then hung in the warehouse for storage. During the long-term use of tower crane cables in the open air, it is easy for the external protective layer to be damaged, resulting in the exposure of internal wires. If not repaired in time, it is easy to cause the damage range to become larger and larger, and then the protective layer of the internal wires is also damaged, resulting in the wire core being exposed outside, which is easy to cause leakage or wire core breakage accidents, affecting the normal operation of the tower crane. Therefore, in the process of coiling the cables after returning to the warehouse, it is also necessary to conduct a comprehensive inspection and detection of the cables in time to find the damaged parts of the cables and inspect and repair them.

[0003] Since a single cable is long and heavy, manual winding and storage not only requires a large work area, but is also difficult and time-consuming. Therefore, in the prior art, a tower crane cable storage machine is usually used to coil and store cables by using a motor to drive the cable drum to rotate. However, this machine does not have a function specifically for repairing old cables, and the overall structure is complex and the manufacturing cost is high. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a tower crane cable storage and repair platform in view of the problem that the tower crane cable storage machine in the prior art cannot inspect and repair the damaged parts of the cables.

The frame includes a main beam and a supporting seat arranged under the main beam, the cable loader and the guide device are respectively arranged at two ends of the main beam, and the middle section of the main beam is provided with an inspection frame for repairing cables, and the cable loader, the guide device and the inspection frame are arranged on the same side of the main beam.

[0006] Furthermore, an electric control platform is provided at the end of the main beam, the motor is fixed on the electric control platform, and the motor is connected to the cable loader by rotating a coupling arranged on the electric control platform.

[0007] Furthermore, the electric control platform includes an oblique brace connected between the main beam and the support seat and a platform covering the oblique brace, the main beam and the support seat.

[0008] Furthermore, the electric control platform is also provided with an electric control box for controlling the operation of the motor.

[0010] Furthermore, the inspection frame is a cross bar arranged on the main beam at one side of the cable loader.

[0011] Furthermore, a vertical wire bolt is provided on the crossbar.

[0012] Furthermore, the guide device includes a movable guide mechanism, which includes an adjusting rod rotatably arranged on the main beam and a guide wheel group rotatably arranged on the adjusting rod for the cable to pass through; the rotating axis of the adjusting rod and the rotating axis of the motor are perpendicular to each other; the relative position of the guide wheel group with respect to the cable loader can be adjusted by rotating the adjusting rod, so as to guide the cable to a suitable position of the cable loader, avoiding the cables from piling up in a local part of the cable loader to form mutual stacking and squeezing, making it easier to organize the tower crane cables and more orderly to coil them.

[0013] Furthermore, the guide device also includes an oblique guide mechanism for guiding the cable into the movable guide mechanism, the oblique guide mechanism includes a main rod obliquely arranged on the main beam, a guide groove fixed on the main rod, and a guide wheel group respectively arranged at the input end and output end of the guide groove, and the horizontal position of the guide groove input end is higher than the horizontal position of the guide groove output end; so that the cable is lifted to a certain height and suspended in the air, and the gravity of the suspended part of the cable at its end can naturally rotate to release deformation stress, thereby avoiding twisted cables from being transported to the winding drum, so as to ensure that the collected cables are more neat.

[0014] Furthermore, it also includes a cable management device for arranging the cables introduced by the guide device, the cable management device and the guide device are arranged on the same side of the main beam, and the main beam is provided with a sleeve that matches the cable management device; the cable management device includes a cable management roller rotatably arranged in the sleeve and an extrusion wheel rotatably arranged on the main beam; the circumferential surface of the cable management roller is provided with an annular groove for winding the cable, and the minimum spacing between the groove wall of the annular groove and the circumferential surface of the extrusion wheel is matched with the diameter of the cable; so that the cable can be just embedded between the extrusion wheel and the groove wall of the annular groove, and the bent cable can be straightened by the extrusion wheel to ensure that the cable wound on the reel is flat, avoiding manual arrangement and greatly improving efficiency.

[0015] The implementation of the tower crane cable storage and maintenance platform of the utility model has the following beneficial effects: by setting a frame including a main beam and a support seat, the entire frame is composed of a frame structure, and the rods of the abandoned boom or standard frame in the tower crane can be fully utilized for processing and manufacturing, which is both environmentally friendly and cost-saving; by setting an inspection frame in the middle section of the main beam, and setting the guide device and the cable loader at both ends of the main beam, the operator can observe the cables between the guide device and the cable loader at the inspection frame, and promptly find the damaged parts of the cables; and when a damaged cable is found, the motor is paused, and the damaged part of the cable is placed on the inspection frame for timely repair. The entire inspection platform can not only quickly coil the cable into a roll, but also inspect and test the cable, and promptly inspect and repair the damaged part of the cable.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] like Figure 1 As shown, in the preferred embodiment of the tower crane cable storage and maintenance platform of the utility model, it mainly includes a frame 10, a motor 21 arranged on the frame 10, a cable loader 100, and a guide device. The cable loader 100 is rotatably arranged on the frame 10 and driven by the motor 21, and the guide device guides the cable 1 into the cable loader 100. The frame 10 includes a main beam 11 and a support seat 12. The cable loader 100 and the guide device are respectively arranged at both ends of the main beam 11. The middle section of the main beam 11 is provided with a maintenance frame 13. The cable loader 100, the guide device and the maintenance frame 13 are arranged on the same side of the main beam 11, and the motor 21 is arranged on the other side of the main beam 11.

[0030] Specifically, the inspection frame 13 is provided on a cross bar 13a on the main beam 11 at one side of the cable loader. Preferably, a vertical wire bolt 14 is provided on the cross bar 13a to locate the damaged part of the cable.

[0031] In this preferred embodiment, an electric control platform 20 is preferably provided at one end of the main beam 11 where the cable loader is provided. The electric control platform 20 is located on the other side of the main beam opposite to the cable loader. A motor 21 is fixedly provided on the electric control platform 20. The motor 21 is connected to the cable loader 100 through a coupling 22. The coupling 22 is rotatably provided on the electric control platform 20. Specifically, the electric control platform 20 may include an oblique brace 23 and a table 24, wherein the oblique brace 23 is connected between the main beam 11 and the support seat 12, and the table 24 is provided to cover the oblique brace 23, the main beam 11 and the support seat 12. The oblique brace 23, the main beam 11 and the support seat 12 can all be made of the remaining rods after the abandoned tower crane boom or the standard frame is disassembled and split.

[0032] In this preferred embodiment, an electric control box 25 is preferably provided on the electric control platform 20 , and the electric control box 25 is used to control the operation of the motor 21 .

[0033] like Figure 3 , 3aAs shown in FIG. 3b, in this preferred embodiment, the cable loader 100 preferably includes a fixed frame 110 connected to the coupling 22, a movable frame 120 hinged at one end on the fixed frame 110, a limit frame 130 arranged at the ends of the fixed frame 110 and the movable frame 120, two cable bearing surfaces 140 respectively arranged on the movable frame 120 and the fixed frame 110, and an assembly and disassembly link mechanism 150 arranged between the movable frame 120 and the fixed frame 110 for quickly adjusting the distance between the cable bearing surfaces 140. Specifically, the cable bearing surface 140 can be made of a plate material, and the cable bearing surface 140 is preferably set to be an arc-shaped cylinder protruding outward, and the cross-sectional shape of the arc-shaped cylinder can be a circular arc or an elliptical arc. Preferably, a flange 111 connected to the coupling 22 is provided at one end of the fixed frame 110, and an open slot 112 matched with the limit frame 130 is provided at the other end. A limit bolt 113 is provided in the open slot 112. When the limit frame 130 is inserted into the open slot 112 of the fixed frame, the limit bolt 113 can limit the limit frame 130 from leaving the open slot 112. The movable frame 120 includes a hinged end 121 hinged on the fixed frame and an open end 122 matched with the limit frame. The hinged end 121 of the movable frame is arranged close to the flange 111 of the fixed frame. The hinge between the movable frame and the fixed frame is arranged at a suitable position so that the cable bearing surface 141 on the movable frame and the cable bearing surface 142 on the fixed frame are exactly located at an axisymmetric position relative to the rotation center axis X1 of the coupling. The open end 122 is also provided with an open slot 123, and a limiting bolt 124 is also provided in the open slot 123. When the limiting frame 130 is inserted into the open slot 123 at the open end of the movable frame, the limiting bolt 124 can limit the limiting frame 130 from being separated from the open slot 123. The limiting frame 130 is arranged at the ends of the movable frame and the fixed frame, and can prevent the cable 1 from being separated from the cable bearing surfaces 141 and 142.

[0034] The assembly and disassembly link mechanism 150 is arranged between the fixed frame 110 and the movable frame 120. By adjusting the distance between the movable frame 120 and the fixed frame 110, the distance between the two cable bearing surfaces 141 and 142 can be quickly adjusted. Preferably, the assembly and disassembly link mechanism 150 includes an upper link 151, a lower link 152, and a limit pin 153 connected between the upper and lower links, wherein one end 151a of the upper link is hinged to the movable frame 120 and the other end 151b is hinged to the lower link 152; one end 152a of the lower link is hinged to the fixed frame 110 and the other end 152b is hinged to the upper link 151. Bolt holes 154 are arranged at corresponding positions of the upper and lower links 151 and 152, and the upper and lower links 151 and 152 are hinged together by bolts 155. Pin holes 156 cooperating with limit pins 157 are provided at corresponding positions of the upper and lower connecting rods 151 and 152. When the upper and lower connecting rods 151 and 152 are in the same line, the limit pins 157 can be inserted into the pin holes 156 of the upper and lower connecting rods, so that the upper and lower connecting rods 151 and 152 no longer rotate relative to each other around the hinge, thereby fixing the relative position between the movable frame 120 and the fixed frame 110, so that the distance between the two cable bearing surfaces 141 and 142 no longer changes.

[0035] When the upper and lower connecting rods 151 and 152 are collinear, the distance between the two cable bearing surfaces 141 and 142 is the largest. At this time, the limit pin 157 is inserted, the relative position between the upper and lower connecting rods 151 and 152 is fixed, and the distance between the two cable bearing surfaces 141 and 142 is also fixed; the introduced cable 1 is wound on the outside of the two cable bearing surfaces 141 and 142, and the cable 1 is tightly attached to the outside of the cable bearing surfaces 141 and 142. When the limit pin 157 is removed and the upper and lower connecting rods 151 and 152 are pushed to rotate relative to each other around the hinge, the upper and lower connecting rods 151 and 152 are no longer collinear, the distance between the two cable bearing surfaces 141 and 142 becomes smaller, and the cable 1 wound on the two cable bearing surfaces 141 and 142 is no longer tightly attached to the outside of the cable bearing surfaces 141 and 142, and the wound cable 1 can be quickly removed using auxiliary tools such as slings.

[0036] like Figure 4 , 4aAs shown in Figures 4b, in this preferred embodiment, the guide device is preferably provided to include a movable guide mechanism 200 and an oblique guide mechanism 300. Among them, the movable guide mechanism 30 includes an adjusting rod 210 and a guide wheel group 220. The adjusting rod 210 is rotatably set on the main beam 11, and the rotation axis of the adjusting rod is perpendicular to the rotation axis of the motor. Specifically, the guide wheel group 220 can be rotatably set on the adjusting rod. When the cable 1 passes through the guide wheel group 50, the guide wheel group 50 can rotate with the position of the adjusting rod 210 relative to the winding drum 2 to adjust the introduction direction of the cable 1, so that the cable 1 is always introduced into the outer surface of the winding drum 2 in a tangential direction, so that the cable 1 is introduced more smoothly and the cable is prevented from twisting. Specifically, a rotating sleeve 15 can be provided on the main beam, and the adjusting rod 211 includes a rotating shaft 211, a guide rod 212 and a lever 213. The rotating shaft 211 is rotatably arranged in the rotating sleeve 15, and the two ends of the rotating shaft 211 are fixedly connected to the guide rod 212 and the lever 213 respectively. The guide wheel group 220 is rotatably arranged at the end 212a of the guide rod. By moving the end of the lever 213 in the rotating plane, the guide rod 212 can be driven to rotate in the rotating plane, thereby adjusting the relative position of the guide wheel group 220 located at the end of the guide rod relative to the cable loader 100. It is best to set the guide rod 212 on the same side of the main beam 11 as the cable loader, and set the lever 213 on the same side of the main beam 11 as the motor. The operator only needs to stand on the side where the motor 21 is set to perform all operations of cable guiding, motor start and stop, and cable maintenance, while avoiding injuries to the operator due to breakage of the cable during transportation, sorting, and winding.

[0037] Preferably, the oblique guide mechanism 300 includes a main rod 310, a guide groove 320, and a guide wheel group 330. The main rod 310 is tilted on the main beam 11, and the guide groove 320 is fixed on the main rod 310. The two ends of the guide groove 320 are an input end 321 and an output end 322, respectively, and each of the input end 321 and the output end 322 is provided with a group of guide wheel groups 330; the tilt angle of the main rod 310 ensures that the horizontal position of the guide groove input end 321 is higher than the horizontal position of the guide groove output end 322. The cross-sectional shape of the guide groove 320 is preferably set to an arc shape that matches the cable 1, so that the cable 1 can be tightly attached to the bottom of the guide groove 320.

[0038] like Figure 5 , 5aAs shown, in this preferred embodiment, it also includes a cable management device 400 for arranging the introduced cables. The cable management device and the guide device are arranged on the same side of the main beam. The main beam is provided with a sleeve 16 that matches the cable management device. It is best to set the sleeve 16 between the oblique guide mechanism 300 and the movable guide mechanism 200. The cable management device 400 includes a cable management drum 410 whose end is rotatably arranged in the sleeve 16 and an extrusion wheel 420 rotatably arranged on the main beam. An annular groove 411 for winding the cable is provided on the circumferential surface of the cable management drum 410. The minimum spacing between the groove wall 411a of the annular groove and the circumferential surface 420a of the extrusion wheel is matched with the diameter of the cable, so that when the cable passes through the extrusion wheel with the cable management drum, it is just squeezed by the extrusion wheel and the groove wall of the annular groove, thereby straightening the bent part of the cable.

[0039] During normal operation, the end of the cable passes through the guide wheel group 330 of the input end 321 of the oblique guide mechanism, passes through the guide groove 320, passes through the guide wheel group 330 of the output end 322 of the oblique guide mechanism, enters the cable management device 400, and passes through the guide wheel group 220 on the adjustment rod of the movable guide mechanism after winding the annular groove 411 of the cable management drum for one or two circles. By manually adjusting the lever 213 of the adjustment rod, the guide rod 212 of the adjustment rod is close to the specified position of the cable bearing surface on the cable loader 100. The motor 21 is controlled by the electric control box 25 to start working. The motor 21 drives the cable loader 100 to rotate through the coupling 22, and drives the cable 1 to be wound on the outside of the cable bearing surface 140. At this time, the dragged cable 1 can automatically rotate after passing through the oblique guide mechanism 300 to reduce cable twisting. At the same time, after being squeezed by the squeezing wheel of the wire management device 400, the bent cable can be straightened; the cable is then guided to the cable loader through the movable guide mechanism 200, so that the cable is wound on the cable bearing surface 140 of the cable loader. When a damaged part is found in the cable, the motor 21 is controlled to stop working through the electric control box 25, and the damaged part of the cable is dragged to the maintenance frame 13 and wound on the wire bolt 14. After the cable is repaired, it is lowered from the maintenance frame, and the motor is started again to sort and coil the cable. When the cable is coiled, remove the limit frame 130 of the cable loader, operate the assembly and disassembly connecting rod mechanism to make the distance between the cable bearing surfaces 141 and 142 on the movable frame and the fixed frame, and then remove the cable.

[0040] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work, any modifications, equivalent substitutions, improvements, etc. made should be included in the protection scope of the present invention.
