Description

Technical Field

[0001] The invention relates to the technical field of busbar casting, in particular to a casting material oscillation filling structure for casting a busbar. Background Art

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large factories and workshops. Traditional cables, used as transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and connection. Busbar trunking has emerged as a new type of distribution conductor. Compared with traditional cables, it fully demonstrates its superiority in high-current transmission. At the same time, due to the use of new technologies and processes, the contact resistance and temperature rise at the connection points of the two ends of the busbar trunking and the plug-in points of the branching ports are greatly reduced. High-quality insulation materials are used in the busbar trunking, thereby improving the safety and reliability of the busbar trunking and making the entire system more complete. Traditional busbar trunking is generally available in two types: dense and air-insulated. Resin-cast fully enclosed busbar trunking is a new type of busbar trunking that has emerged in recent years. It uses a mixture of resin material, curing agent, and quartz sand as the insulating medium and is cast integrally with the conductor.

[0003] At present, a Chinese invention with the announcement number CN106239797B discloses a medium-voltage resin busbar end casting mold, which relates to the field of busbar duct casting. The medium-voltage resin busbar end casting mold includes a base, the front surface of the base is fixedly connected to an inner mold, outer molds are provided on both sides of the inner mold, and the two outer molds are symmetrically arranged, one end of the two outer molds is movably connected to the base, and the other ends of the two outer molds are in contact with each other, the outer mold is provided with a first tooth on the side close to the inner mold, the inner mold is fixedly connected to a rotary seat on the side close to the outer mold, and a rotating rod is provided on the rotary seat, and a rotating wheel is fixedly installed on the surface of the rotating rod located inside the rotary seat, and the surface of the rotating wheel is provided with a second tooth that matches the first tooth. The medium-voltage resin busbar end casting mold does not require a separate prying tool, which saves the time consumed in taking out the prying tool, reduces the difficulty of operation for the operator, saves time and effort, is simple and fast to adjust, and has high demoulding efficiency;

[0004] The current resin bus duct casting process is to mix the resin material with the curing agent and quartz sand, and then pour it into a mold pre-installed with a conductor. The mixture is filled in the space between the mold and the conductor by its own weight, and then left to solidify naturally. However, due to the presence of air between the inside of the mold and the busbar, after pouring the resin material into the mold, some of the air cannot be discharged, and the resin material cannot be evenly filled into the busbar surface. As a result, not only bubbles will appear inside the resin material after it solidifies, but the surface of the bus duct casting structure will also be incomplete and have certain defects.

[0005] In order to solve the above problems, we propose a castable oscillating filling structure for casting busbars. Summary of the Invention

[0006] The purpose of the present invention is to provide a casting material oscillation filling structure for casting a busbar, which has the advantage of oscillating and shaking the resin casting material of the busbar in multiple directions so that the material is evenly filled into the busbar surface.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: A castable material oscillating filling structure for casting a busbar, comprising a casting mold, an oscillating connecting plate provided at the bottom of the casting mold, and a fixed base plate provided at the bottom of the oscillating connecting plate; a double-headed servo motor is mounted on one side of the top of the fixed base plate, the output end of the double-headed servo motor is fixedly connected to a crank connecting rod, the end of the crank connecting rod remote from the double-headed servo motor is rotatably connected to a transmission connecting rod rotatably connected to the side of the bottom of the oscillating connecting plate remote from the double-headed servo motor; the front and back sides of the oscillating connecting plate and the fixed base plate are both fixedly connected to inclined connecting plates, and the front and back sides of the oscillating connecting plate and the fixed base plate are both provided with spring plates fixedly connected to the inclined connecting plates; a fixed cylinder is mounted on the top of the oscillating connecting plate, a sliding rod fixedly connected to the bottom of the casting mold is slidably connected to the interior of the fixed cylinder, and a vibration spring fixedly connected to the bottom of the sliding rod is fixedly connected to the interior of the fixed cylinder; a busbar is mounted inside the casting mold, and castable material baffles used in conjunction with the busbar are slidably connected to both sides of the interior of the casting mold.

[0008] By adopting the above technical solution, the double-headed servo motor is turned on to drive the crank connecting rod to rotate at high speed, and the spring sheet is continuously stored and released to make the transmission connecting rod drive the oscillation connecting plate to vibrate left and right at high frequency. At the same time, the oscillation connecting plate vibrates left and right at high frequency continuously, and the vibration spring can be continuously compressed by the sliding rod and then rebounded, so that the vibration spring can also drive the sliding rod to slide up and down at high frequency inside the fixed tube, so that the casting mold can be set to vibrate at high frequency in the up and down and left and right directions, and the resin casting material of the busbar can be shaken in multiple directions to make it oscillate and shake evenly, so that the material is evenly filled into the busbar surface, reducing the defects on the surface of the busbar trough casting structure, and avoiding the appearance of large bubbles inside the solidified resin material, and reducing the appearance of small bubbles, thereby improving the quality of the busbar trough casting structure.

[0009] The present invention is further configured such that: the sides of the casting material baffles close to each other and the interior of the casting mold are both bonded with anti-sticking films.

[0010] The above technical solution can avoid the resin material from sticking to the casting mold and the casting material baffle after pouring, making it easier to remove the bus duct from the inside of the casting mold after the resin material is solidified.

[0011] The present invention is further configured as follows: a sealing ring is installed inside the castable baffle and is in sliding friction connection with the busbar.

[0012] By adopting the above technical solution, the sealing performance of the connection between the casting material baffle and the busbar is improved, and the resin material is prevented from leaking out of the connection.

[0013] The present invention is further configured such that both sides of the bottom of the casting material baffle and both sides of the top of the casting mold are fixedly connected with magnet blocks that are magnetically connected to each other.

[0014] The above technical solution facilitates the rapid fixing of the casting material baffle on the top of the casting mold and the rapid separation of the casting material baffle and the casting mold.

[0015] The present invention is further configured as follows: telescopic rods are provided at both ends of the casting mold, a fixed rod is provided at one end of the telescopic rod away from the casting mold, and both ends of the telescopic rod are fixedly connected to universal ball joints respectively fixedly connected to the casting mold and the fixed rod.

[0016] By adopting the above technical solution, the two ends of the casting mold can be supported by installing a fixed rod and a telescopic rod. At the same time, when the casting mold vibrates, the telescopic rod can swing and sway along with the casting mold through the universal ball joint, and the telescopic rod itself can also be telescoped and adjusted along with the vibration of the casting mold.

[0017] The present invention is further configured such that both ends of the fixed base plate are threadedly connected with mounting bolts.

[0018] The above technical solution facilitates the installation and connection of the fixed base plate, thereby fixing the casting mold.

[0019] The present invention is further configured such that: the surface of the sliding rod is sleeved with a buffer pad bonded to the bottom of the casting mold.

[0020] By adopting the above technical solution, by arranging a buffer gasket, the collision between the vibration spring and the casting mold can be buffered when the sliding rod is extended and retracted up and down, thereby increasing the service life and reducing noise.

[0021] The present invention is further configured such that: the casting mold is made of profile aluminum material.

[0022] By adopting the above technical solution, when the resin material is poured into the interior of the casting mold, heat is conducted through the casting mold in contact with the air, thereby improving the heat dissipation efficiency of the resin material, effectively accelerating the curing speed, and improving production efficiency.

[0023] In summary, the present invention has the following beneficial effects:

[0024] The present invention starts a double-headed servo motor to drive the crank connecting rod to rotate at high speed, and continuously stores and releases energy through the spring sheet, so that the transmission connecting rod can drive the oscillation connecting plate to vibrate left and right at high frequency. At the same time, the oscillation connecting plate continuously vibrates left and right at high frequency, and the vibration spring can be continuously compressed by the sliding rod and then rebounded, so that the vibration spring can also drive the sliding rod to slide up and down at high frequency inside the fixed cylinder, so that the casting mold can be set to vibrate at high frequency in the up and down and left and right directions, and realizes the multi-directional oscillation and shaking setting of the resin casting material of the busbar, so that the material is evenly filled into the busbar surface, reducing the defects on the surface of the busbar trough casting structure, and at the same time avoiding the occurrence of large bubbles inside the solidified resin material, and reducing the occurrence of small bubbles, thereby improving the quality of the busbar trough casting structure.
