Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet control devices, specifically an alternating control mechanism for electrical cabinet floor switch and handcart. Background Technology

[0002] To assist or replace humans in various tasks, a variety of inspection and operation robots are constantly emerging. When indoor operation robots perform tasks related to switch cabinets, they need to operate handcarts and floor cutters. However, the handcart heads and floor cutter heads have different shapes and sizes, making it impossible to use the same tools for operation.

[0003] The existing technology has the following technical defects: For switch cabinets that require operation of handcarts and floor switches, indoor inspection operation robots require manual installation of tooling at the handcart position in the cabinet, and then use the floor switch operation tooling to operate the handcart, which wastes human resources and is inconvenient to operate. Utility Model Content

[0004] To address the problems of existing technologies, this utility model provides an alternating control mechanism and method for electrical cabinet floor switch and handcart, which enables robots to operate the switch cabinet without changing the cabinet's appearance or interfering with the original manual operation, thereby reducing the use of human resources and improving work efficiency.

[0005] This utility model includes a base part, a ball spline shaft, a grounding tool spline shaft, a handcart assembly, a grounding tool assembly with a linear slider, and a handcart head.

[0006] The base portion includes a support base, a motor base, a connecting base, and a second connecting base. The motor base is equipped with a motor reducer, which is connected to the ball spline shaft via a synchronous belt structure and controls the extension and retraction of the ball spline shaft.

[0007] The second connecting seat is connected to a driven gear that can rotate freely via a bearing structure. The inner ring of the driven gear is fitted around the outer edge of the ball spline shaft and rotates with the ball spline shaft. One end of the ball spline shaft is fixedly connected to a handcart head, and the other end of the ball spline shaft is provided with a second connecting seat. The second connecting seat is fixed to the linear slider of the grounding knife assembly.

[0008] A telescopic bracket is connected to the base of the support via a sliding mechanism. The telescopic bracket is fixedly connected to the handcart assembly. The telescopic bracket is connected to the grounding cutter spline shaft via a deep groove ball bearing. The handcart assembly extends and retracts along the sliding mechanism with the grounding cutter spline shaft via the telescopic bracket. The sliding mechanism restricts the telescopic bracket from rotating with the grounding cutter spline shaft. A drive gear is fitted on the outer edge of the grounding cutter spline shaft via a positioning flange. The drive gear rotates and extends and retracts with the rotation of the grounding cutter spline shaft. A transition gear meshes and drives the drive gear and the driven gear.

[0009] In a further improvement, the second connecting seat is internally connected to the ball spline shaft via a deep groove ball bearing, and the second connecting seat extends and retracts with the ball spline shaft but does not rotate with it.

[0010] As a further improvement, the ball spline shaft is equipped with a monitoring device to monitor the extension and retraction status of the ball spline shaft.

[0011] In a further improvement, the monitoring device includes an endoscope curing component and a slotted optical coupler. The slotted optical coupler is fixed below the ball spline shaft by a slotted optical coupler seat, and the endoscope curing component is mounted on a second connecting seat.

[0012] In a further improvement, the endoscope curing component includes a floating rod and an endoscope assembled and cured with red glue.

[0013] The advantages of this invention are that it enables robots to operate the switch cabinet without changing the appearance of the cabinet or interfering with the original manual operation, thereby reducing the use of human resources and improving work efficiency. Attached Figure Description

Fourth deep groove ball bearing; 55. Endoscope; 56. Slotted optical coupler.

[0028] The installation process of this utility model is as follows: First, the drive gear 25 and the positioning flange 26 are fixedly connected to the rotating spline shaft of the grounding tool using the fifth socket head cap screw 39 and the sixth socket head cap screw 40. The drive gear 25 can rotate and extend with the rotating spline shaft of the grounding tool. The telescopic bracket 27 is fixed to the spline shaft of the grounding tool through a deep groove ball bearing and is connected to the linear guide slider, so that the telescopic bracket 27 can extend and retract with the spline shaft of the grounding tool, but does not rotate.

[0029] Assemble and cure the floating rod 5 and endoscope 55 with red glue for later use.

[0030] The driven gear 2, connecting seat 9, bearing seat 20, spacer 21, baffle 22, third internal hex socket head cap screw 34, cross-slot countersunk screw 45, and second deep groove ball bearing 47 are assembled to form an assembly, and the driven gear 2 is rotatable relative to the connecting seat 9.

[0031] Continue adding the ball spline fixing sleeve 1, handcart rotating connector 3, ball spline shaft 6, copper nut 14, end cap 23, synchronous pulley 24, elastic retaining ring 37 for the hole, and first deep groove ball bearing 46 to form an assembly. This allows the driven gear 2 to rotate, driving the ball spline shaft 6 to rotate, and the synchronous pulley 24 to rotate, driving the ball spline shaft 6 to extend and retract. Continue adding the handcart head fixing seat 12, handcart head 13, lock nut 15, pin 19, and spring 29 to form an assembly. This fixes the handcart head 13 to the ball spline shaft 6, allowing for a certain amount of free movement. Continue adding the second connecting seat 4, slotted optical coupler seat 11, shaft elastic retaining ring 38, and third deep groove ball bearing 53 to form an assembly. This allows the second connecting seat 4 to both extend and retract with the ball spline shaft 6 and rotate relative to the ball spline shaft 6. Continue by adding a limit plate 8, an oil-free bushing 48, a compression spring 49, a shoulder screw 51, a slotted optical coupler 56, and a floating rod 5 to form a new assembly with the endoscope 55. This allows the endoscope to extend and retract without rotating under external force, triggering the slotted optical coupler 56 to obtain a signal that the handcart head is inserted into position, thus executing the next step. Continue by adding a motor mount 10, a timing pulley 28, a tensioning plate 30, a second hexagon socket head cap screw 33, a timing belt 50, and a motor reducer 52 to form an assembly. This allows the motor reducer 52 to control the extension and retraction of the handcart head 13 via the timing pulley pair. Continue by adding a transition gear 7, a retaining ring 16, a baffle 17, and a fourth deep groove ball bearing 54 to form the handcart assembly.

[0032] The handcart assembly is fixed to the telescopic bracket 27 with an internally threaded cylindrical pin 35 and a fourth internal hexagonal head screw 36, so that the handcart assembly can extend and retract with the grounding knife. Through the driven gear 2, the transition gear 7, and the driving gear 25 of the gear pair, the rotational power of the grounding knife can be transmitted to the handcart head 13, causing the handcart head 13 to rotate.

[0033] Finally, the second connecting seat 4 is fixed to the linear slider of the in-place knife assembly to support the ball spline shaft 6, and to ensure that the endoscope curing component only extends and retracts with the ball spline shaft 6 without rotating.

[0034] When operating the floor cutter, the floor cutter head extends to a certain position close to the counter, and then the handcart head 13 retracts completely into place before performing the floor cutter operation. When operating the handcart, the handcart assembly follows the floor cutter head to a certain position close to the counter and then the handcart head 13 extends out separately to perform the handcart operation.
