Description

Technical Field

[0001] The utility model relates to the technical field of crane collector technology, in particular to a crane sliding line collector mechanism. Background Art

[0002] The busbar collector is the main device for collecting electric energy on the collector side of the busbar system. It conducts electric energy directly to the electrical appliances through the sliding contact between the collector brush and the guide rail, thus realizing the mobile power supply of the system. The busbar collector consists of three parts: the insulating part of the mechanical structure, the tension device, and the collector brush that is in direct sliding contact with the guide rail.

[0003] The busbar relay is an important component for mobile equipment to draw power from the busbar. The collector has a mechanical structure and a conductive brush head. It plays a role in the conduction of electricity to a certain extent. It converts the electrical energy from the busbar to the mobile equipment into mechanical energy, thereby achieving what we call the role of driving the equipment to move.

[0004] To replace the brushes of the existing sliding line collector, the power supply of the current section of the sliding line must be shut down, affecting the operation of multiple overhead cranes. Since the brush is a consumable part, it needs to be replaced regularly. Planned replacement does not affect the production rhythm, but sudden replacement directly affects the operation of the entire overhead crane and will have an impact on production capacity.

[0005] Therefore, we propose a crane sliding line current collector mechanism to solve the above-mentioned problems. Utility Model Content

[0006] The utility model provides a crane sliding wire collector mechanism, which solves the problem mentioned in the above background technology that when replacing the brushes of the existing sliding wire collector, the power supply of the current section of the sliding wire needs to be shut down, which affects the travel of multiple overhead cranes. Because the brush is a consumable part, it needs to be replaced regularly. Planned replacement does not affect the production rhythm, but sudden replacement directly affects the operation of the entire section of the overhead crane and has an impact on production capacity.

[0007] The utility model provides the following technical solution: a traveling sliding line current collector mechanism, comprising two bottom plates and a conductive copper plate fixedly mounted on the upper ends of the bottom plates, a connecting plate fixedly mounted between the two bottom plates, a rotating mechanism fixedly mounted on the side of the bottom plates, a brush clamped in the rotating mechanism, two fixed plates fixedly mounted on one side of the rotating mechanism, and insulators fixedly mounted on the side walls of the two fixed plates.

[0008] As an optional solution described in the utility model, the rotating mechanism includes two fixing rods fixedly installed on the side of the base plate, both sides of the inner walls of the two fixing rods are rotatably connected with clamping rods, and the brush is clamped between the two clamping rods.

[0009] As an optional solution described in the utility model, wherein: both ends of the outer sides of the two fixed rods are rotatably connected with connecting rods, and a rotating rod is rotatably connected between the inner walls of the upper ends of the two fixed rods, and the rotating rod is fixedly connected to the connecting rod.

[0010] As an optional solution described in the utility model, a movable rod is rotatably connected between the two connecting rods, and springs are sleeved on the movable rods. The two ends of the springs are respectively fixedly connected to the inner walls of the two connecting rods.

[0011] As an optional solution described in the utility model, wherein: the brush is rotatably connected between the two clamping rods, and the brush is slidably connected in the connecting plate.

[0012] As an optional solution described in the utility model, wherein: a connector 1 is fixedly installed on the upper ends of the two fixed plates, a connector 2 is fixedly installed on the two conductive copper plates, and a wire is fixedly connected between the connector 1 and the connector 2.

[0013] The utility model has the following beneficial effects:

[0014] 1. After the brushes are used to a certain extent, their conductivity decreases. When the brushes need to be replaced, the rotating mechanism can be rotated. When the rotating mechanism rotates, it drives the brushes clamped between the rotating mechanisms to rotate together until the brushes are rotated to contact the fixed plate. At this time, under the protection of the insulator, the brushes can be removed from the rotating mechanism and replaced with new ones. The collector bracket structure of the traveling crane sliding line is modified to increase the rotating mechanism. When the brushes need to be replaced, the rotating mechanism can be rotated. After rotation, the brushes can be separated from the conductive sliding line, so there is no need to shut down the entire sliding line. As long as the current overhead crane is powered off, the actual application effect is better.

[0015] 2. In the initial state, the connecting rods on both sides are tightly against the inner walls of the two fixed plates. At this time, the springs are in a compressed state. Under the action of the springs, the brushes are clamped. When the connecting rods on both sides rotate at the same time, they slowly slide away from between the two fixed plates. At this time, the connecting rods are pushed to both sides under the action of the springs. The two connecting rods slide outward along the side walls of the movable rods. When the connecting rods rotate, the two clamping rods at the other end are driven to rotate together. When the two connecting rods slide until they are pushed outward by the springs, the brushes between the two clamping rods are changed from a clamped state to a slidable state. At this time, the brushes can be replaced. After the replacement is completed, the brushes can be clamped again by rotating the connecting rods. The device can complete the clamping and loosening of the brushes by rotating the connecting rods, and the operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-Figure 3 A traveling sliding line current collector mechanism comprises two bottom plates 1 and a conductive copper plate 11 fixedly mounted on the upper end of the bottom plates 1, a connecting plate 12 is fixedly mounted between the two bottom plates 1, a rotating mechanism 4 is fixedly mounted on the side of the bottom plates 1, a brush 5 is clamped in the rotating mechanism 4, two fixed plates 3 are fixedly mounted on one side of the rotating mechanism 4, and insulators 31 are fixedly mounted on the side walls of the two fixed plates 3.

[0024] After the brush 5 has been used to a certain extent, its conductivity decreases. When the brush 5 needs to be replaced, the rotating mechanism 4 can be rotated. When the rotating mechanism 4 rotates, it drives the brush 5 clamped between the rotating mechanism 4 to rotate together until the brush 5 is rotated to contact with the fixed plate 3. At this time, under the protection of the insulator 31, the brush 5 can be removed from the rotating mechanism 4 and replaced with a new brush 5. The device has a modified collector bracket structure and an additional rotating mechanism 4. When the brush 5 needs to be replaced, the rotating mechanism 4 can be rotated. After rotation, the brush 5 can be separated from the conductive sliding wire, and there is no need to shut down the entire sliding wire. As long as the current overhead crane is powered off, the actual application effect is good.

[0025] Example 2

[0026] See also Figure 2-Figure 4 The rotating mechanism 4 includes two fixed rods 41 fixedly installed on the side of the base plate 1, and the inner walls of the two fixed rods 41 are rotatably connected with clamping rods 44 on both sides. The brush 5 is clamped between the two clamping rods 44. Under the cooperation between the fixed rods 41, the clamping rods 44 and the brush 5, the brush is clamped in the fixed rods 41 through the two clamping rods 44.

[0027] The outer ends of the two fixed rods 41 are rotatably connected with connecting rods 43, and the upper inner walls of the two fixed rods 41 are commonly rotatably connected with a rotating rod 42. The rotating rod 42 is fixedly connected to the connecting rod 43. With the cooperation between the fixed rods 41, the connecting rod 43 and the rotating rod 42, the upper and lower connecting rods 43 can be rotatably connected to the side walls of the fixed rods 41.

[0028] A movable rod 46 is connected between the two connecting rods 43 for common rotation, and a spring 45 is sleeved on the movable rod 46. The two ends of the spring 45 are respectively fixedly connected to the inner walls of the two connecting rods 43. With the cooperation between the connecting rods 43, the movable rod 46 and the spring 45, the movable rod 46 can increase the stability of the connecting rods 43 on both sides, and the spring 45 can automatically clamp the brush 5 when the two connecting rods 43 rotate between the two fixed plates 3.

[0029] The brush 5 is rotatably connected between the two clamping rods 44, and the brush 5 is slidably connected in the connecting plate 12. When the brush 5 is in the connecting plate 12, it is in a working state, and the circuit is closed at this time.

[0030] A connector 1 32 is fixedly installed on the upper ends of the two fixed plates 3, and a connector 2 13 is fixedly installed on the two conductive copper plates 11. A wire 2 is fixedly connected between the connector 1 32 and the connector 2 13. With the cooperation between the fixed plates 3, the connector 1 32, the conductive copper plates 11, the connector 2 13, and the wire 2, the conductive copper plates 11 on both sides and the fixed plates 3 can be connected through the wire 2 to form a loop.

[0031] After the brush 5 has been used to a certain extent, its conductivity decreases. When the brush 5 needs to be replaced, the connecting rods 43 on both sides can be rotated. In the initial state, the connecting rods 43 on both sides are tightly against the inner walls of the two fixed plates 3. At this time, the springs 45 are in a compressed state. Under the action of the springs 45, the brush 5 is clamped. When the connecting rods 43 on both sides are rotated at the same time, they slowly slide away from between the two fixed plates 3. At this time, under the action of the springs 45, the connecting rods 43 are pushed to both sides, and the two connecting rods 43 slide outward along the side walls of the movable rod 46. When the connecting rod 46 rotates, the two clamping rods 44 at the other end are driven to rotate together. When the two connecting rods 43 slide until they are pushed outward by the springs 45, the brush 5 between the two clamping rods 44 is changed from a clamped state to a slidable state, and the brush 5 can be replaced at this time. After the replacement is completed, the brush 5 can be clamped again by rotating the connecting rod 43. The device can complete the clamping and loosening of the brush 5 by rotating the connecting rod 43, and the operation is simple.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention.
