Description

Technical Field

[0001] The present invention belongs to the technical field of cable tool design, and particularly relates to a large cable reel support. Background Art

[0002] Some cable reels have a diameter of nearly five meters and a weight of nearly 40 tons. When loading and unloading such heavy large cable reels, professional lifting equipment is required. Improper operation is likely to cause casualties and equipment damage. Most of the existing supports for carrying cable reels are simple fixed and non-adjustable structures. When installing such a large cable reel on a carrying support or erecting it overhead, the heavy cable reel requires higher requirements for the lifting equipment. If the lifting capacity of the lifting equipment is limited, it may not be able to lift the cable reel at one time, and it is necessary to adjust or replace the equipment multiple times, which will prolong the installation time. Moreover, the skills and experience requirements for operators during the lifting process are also higher. If the operation is improper, it may also trigger safety accidents, further affecting the construction efficiency.

[0003] In addition, the excessive weight of the cable reel will increase the rotational resistance of the cable reel during the wire laying process. On the one hand, construction workers need to apply greater force to drive the cable reel to rotate, which will slow down the wire laying speed. On the other hand, the cables may be entangled and knotted with each other, resulting in poor wire laying. On the other hand, the greater resistance may also cause the cable to jam during the wire laying process, requiring construction workers to constantly adjust, reducing the continuity and efficiency of wire laying, and increasing the construction difficulty and time cost.

[0004] In addition, manually pulling the cable for wire laying operations will make the wire laying speed of the cable reel uneven, which may cause the cable to be strained or damaged.

[0005] In the prior art, there is also a solution of setting the carrying support as a liftable structure. For example, in the technical solution of the existing patent application with the publication number CN119750304A, the lifting of the cable reel is realized by arranging an oil cylinder inside the support. Although this structure can adjust the installation height of the carrying support to adapt to the size of the cable reel when the cable reel is installed on the carrying support, and lift the cable reel after the cable reel is installed on the carrying support to achieve overhead erection, the carrying support of this structure uses a single oil cylinder to achieve lifting, and the weight of the cable reel is fully applied to the oil cylinder, requiring high load-bearing capacity of the oil cylinder, and is only suitable for use with lighter small cable reels and not suitable for heavy large cable reels.

[0006] In the prior art, there is also a solution of using the structure of a driving roller and a driven roller to actively drive the cable reel to rotate and achieve active wire laying of the cable reel. For example, in the technical solution of the existing patent application with the publication number CN119750304A, but the weight of the cable reel in this solution is entirely borne by the driving roller and the driven roller, and the radial pressure on the driving roller is relatively large, and it is also only suitable for use with lighter cable reels. Summary of the Invention

[0007] The present invention provides a large cable reel support, aiming to solve the problems existing in the above-mentioned prior art. The large cable reel support includes two bearing supports, and the cable reel is hinged on the two bearing supports. The bearing support further includes: A frame body, which is an isosceles trapezoid formed by a bottom plate, a top plate and two side plates; A lifting oil cylinder, vertically fixed on the bottom plate, the oil rod of which passes through the top plate from bottom to top, and a hinge seat for hinging the cable reel is arranged at the upper end of the oil rod; A threaded locking rod, vertically fixed on the hinge seat, the bottom end of which passes through the top plate from top to bottom; a locking nut is connected to the threaded locking rod, and the locking nut is located between the hinge seat and the top plate. The locking nut is used to rotate to abut against the top plate to assist in locking the lifting oil cylinder, or rotate to disengage from the top plate to unlock the lifting oil cylinder; Drive seats, there are two drive seats, the two drive seats are respectively arranged on the two side plates, a freely rotating supporting wheel is arranged on the drive seat, and a hydraulic motor for driving the corresponding supporting wheel to rotate is arranged on one of the drive seats; a telescopic oil cylinder is arranged on the side plate, and the telescopic oil cylinder is used to drive the drive seat to move along the side plate, so as to drive the supporting wheel to contact or disengage from the cable reel.

[0008] In a specific embodiment, the axis of the lifting oil cylinder coincides with the midline of the frame body, a plurality of threaded locking rods are arranged and are arranged on both sides of the lifting oil cylinder, and the threaded locking rods are T-shaped screw rods.

[0009] In a specific embodiment, a hollow shaft corresponding to the threaded locking rod is further connected between the top plate and the bottom plate, and the threaded locking rod is inserted into the hollow shaft.

[0010] In a specific embodiment, a mounting plate is arranged on the side plate, a guide rod is arranged on the mounting plate, the drive seat is slidably arranged on the guide rod, the telescopic oil cylinder is arranged on the mounting plate, and the oil rod of the telescopic oil cylinder is connected to the drive seat.

[0011] In a specific embodiment, a lifting lug for hoisting is arranged on the top plate.

[0012] In a specific embodiment, a hydraulic station and an electric control cabinet are further included. The hydraulic station further includes a motor oil pump, the motor oil pump is connected to the lifting oil cylinder, the telescopic oil cylinder and the hydraulic motor through an oil circuit, a valve is arranged on the oil circuit, and the motor oil pump is electrically connected to a controller in the electric control cabinet.

[0013] The present invention has the following beneficial effects: The hinge seat on the large cable reel support, which is hinged to the cable reel, can be automatically lifted and lowered under the action of the lifting cylinder, making the installation of the cable reel and the hinge seat convenient, suitable for cable reels of different sizes, and eliminating the need for a crane to cooperate during the installation process, shortening the operation time and saving the hoisting cost. After the cable reel is installed on the frame, it can be lifted or lowered as needed, facilitating the adjustment of the cable reel to the appropriate wire-releasing height and angle. The isosceles trapezoidal frame, in cooperation with the lifting cylinder and the threaded locking rod with a locking nut, can provide stable support, is suitable for heavy large cable reels, ensures that the cable reel will not shake or tilt during the wire-releasing process, and solves the problem of insecure fixation of the cable reel during loading and transportation. The supporting wheels provided on the two side plates, when in rolling contact with the cable reel, can, on the one hand, assist in stably fixing the cable reel on the frame, and on the other hand, actively drive the cable reel to rotate, eliminating the need for a large amount of manpower and various auxiliary equipment for wire-releasing, significantly reducing the wire-releasing resistance, reducing the labor intensity of the operators, and improving the efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Please refer to Figures 1 - 3 , a large cable reel support provided by the present invention includes two bearing supports 1, the cable reel 2 is hinged to the two bearing supports 1, and the bearing support 1 further includes: a frame, a lifting cylinder 12, a threaded locking rod 13 and a drive seat 14.

[0019] The frame is composed of a bottom plate 111, a top plate 112 and two side plates 113 to form an isosceles trapezoid. This structure has a high load-bearing capacity and stability, and is more suitable for the heavy large cable reel 2 to be carried in this solution.

[0020] The lifting oil cylinder 12 is vertically fixed on the bottom plate 111, and its oil rod passes through the top plate 112 from bottom to top. A hinge seat 121 is provided at the upper end of the oil rod, and a freely rotatable rotating shaft is provided on the hinge seat 121. The rotating shaft is inserted into the central tube of the cable reel 2, thereby realizing the hinged connection between the hinge seat 121 and the cable reel 2. The axis of the lifting oil cylinder 12 coincides with the center line of the frame body, so that the center of gravity of the cable reel 2 is located at the center of the two frame bodies to ensure stability.

[0021] The threaded locking rod 13 is vertically fixed on the hinge seat 121, and its bottom end passes through the top plate 112 from top to bottom. A locking nut 131 is connected to the threaded locking rod 13. The locking nut 131 is located between the hinge seat 121 and the top plate 112. The locking nut 131 can be rotated to abut against the top plate 112 to assist in locking the lifting oil cylinder 12, or rotated to disengage from the top plate 112 to unlock the lifting oil cylinder 12. A plurality of threaded locking rods 13 are provided and arranged on both sides of the lifting oil cylinder 12. The threaded locking rod 13 is a T-shaped screw rod. By providing the threaded locking rod 13 to assist in locking the lifting oil cylinder 12, a part of the gravity of the cable reel 2 is borne by the lifting oil cylinder 12, and the other part is transmitted by the threaded locking rod 13 to the locking nut 131, and then to the isosceles trapezoidal frame body. Compared with the existing bearing bracket 1 that only uses the lifting oil cylinder 12 and the support rod to bear the gravity of the cable reel 2, the bearing capacity of the structure that jointly bears the gravity of the cable reel 2 in this solution is stronger, the stability is better, and it is more suitable for use with large cable reels 2. A hollow shaft 132 corresponding to the threaded locking rod 13 is also connected between the top plate 112 and the bottom plate 111. The threaded locking rod 13 is inserted into the hollow shaft 132 to prevent the threaded part of the threaded locking rod 13 from being exposed, which may easily cause safety accidents or damage. In addition, it can also play a guiding role in the lifting and lowering movement of the threaded locking rod 13 along with the lifting oil cylinder 12.

[0022] A lifting lug 117 is also provided on the top plate 112, which is convenient for lifting the frame body, or for lifting the cable reel 2 together with the two bearing brackets 1 after it is installed.

[0023] There are two driving seats 14, which are respectively arranged on two side plates 113. An installation plate 114 is provided on the side plate 113, and a guide rod 115 is provided on the installation plate 114. The driving seat 14 is slidably arranged on the guide rod 115. A freely rotatable supporting wheel 141 is arranged on the driving seat 14. A traveling transmission device is arranged on one of the driving seats 14. The traveling transmission device integrates a hydraulic rotating device, and the hydraulic rotating device further integrates a speed reducer and a hydraulic motor 142. The oil circuit of the hydraulic station is communicated with the oil inlet and outlet of the hydraulic motor 142, so as to drive the hydraulic motor 142 and the speed reducer to rotate through hydraulic oil. The speed reducer then drives the corresponding supporting wheel 141 to rotate through the rotating shaft of the supporting wheel 141. The hydraulic motor 142 can provide high torque output at low speed, which is suitable for the application scenario of driving the large cable reel 2 in this application. Moreover, the hydraulic motor 142 can achieve smooth stepless speed change, which can solve the problem of wire feeding jamming to a certain extent. An expansion cylinder 116 is arranged on the installation plate 114. The oil rod of the expansion cylinder 116 is connected to the driving seat 14. The expansion cylinder 116 is used to drive the driving seat 14 to move along the side plate 113, so as to drive the supporting wheel 141 to contact or disengage from the cable reel 2.

[0024] It further includes a hydraulic station 3 and an electric control cabinet 4. The hydraulic station 3 further includes a motor oil pump. The motor oil pump is connected to the lifting cylinder 12, the expansion cylinder 116 and the hydraulic motor 142 through an oil circuit, and a valve is provided on the oil circuit. The valve is a multi-way valve, which is connected between the main oil circuit and each branch oil circuit, so as to realize supplying hydraulic oil to the lifting cylinder 12, the expansion cylinder 116 and the hydraulic motor 142 respectively through the cooperation of the hydraulic station 3 and the valve. The motor oil pump is electrically connected to the controller in the electric control cabinet 4, so as to realize controlling the motor oil pump of the hydraulic station 3 to work through the controller in the electric control cabinet 4. Of course, the valve can be a solenoid valve, and the solenoid valve is electrically connected to the controller in the electric control cabinet 4 to realize automatic control of the valve to work. It should be noted that the cooperation of the hydraulic station 3 and the valve to supply hydraulic oil to the lifting cylinder 12 and the expansion cylinder 116 respectively is an existing hydraulic control technology, and its specific working principle will not be elaborated here. The principle of the controller controlling the motor oil pump 3 and the solenoid valve to work is also an existing technology.

[0025] The working principle of the present invention is as follows: when transporting the cable drum 2, the cable drum 2 and the two supporting brackets 1 are first hoisted onto the transport vehicle respectively, and then the hinge seat 121 on the supporting bracket 1 is driven to the height of docking with the cable drum 2 by the lifting cylinder 12 on the transport vehicle, and the rotating shaft on the hinge seat 121 is inserted into the central tube of the cable drum 2, so that the cable drum 2 and the hinge seat 121 are hinged together. Then the cable drum 2 is lifted by the lifting cylinder 12 to be out of contact with the transport vehicle, and then the driving seat 14 is driven to move along the side plate 113 by the telescopic cylinder 116, so that the supporting wheel 141 contacts the cable drum 2, further ensuring the stability of the cable drum 2, thereby completing the assembly of the cable drum 2 and the two supporting brackets 1. Of course, the cable drum 2 and the two supporting brackets 1 can also be assembled on the ground, and then hoisted as a whole to the transport vehicle through the lifting lugs 117 set on the top plate 112 of the frame. During the wire-laying operation, the controller in the electric control cabinet 4 controls the motor oil pump and the valve in the hydraulic station 3 to cooperate, thereby controlling the operation of the hydraulic motor 142, thereby driving the corresponding supporting wheel 141 to rotate. The rotation of the supporting wheel 141 drives the cable drum 2 to rotate, thereby realizing active wire-laying operation. In addition, during the wire-laying operation, the lifting cylinder 12 can be controlled to adjust the height of the cable drum 2 through the cooperation of the motor oil pump and the valve, thereby adjusting the wire-laying angle, and the speed of the hydraulic motor can be adjusted through the frequency converter provided by the motor oil pump, thereby adjusting the wire-laying speed.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions and substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the protection scope of the present invention.
