DETAILED DESCRIPTION
[0035] 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 of 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.
[0036] This patent is mainly used in conjunction with the railway vehicle hook body 13 maintenance assembly line to meet the hook body 13 on the circulation line. The insertion and withdrawal of the hook body 13 may be easy in some hook bodies 13 and take a short time, while some take a long time. It is not suitable to use a fixed position. Therefore, a mobile position is used to improve the fault tolerance of the insertion and withdrawal work. It only needs to ensure the overall time of this work. Therefore, this patent provides a mobile hook ear hole insertion and withdrawal machine, such as Figure 1-7 As shown, it includes a track 1, a moving trolley 2, a driving mechanism 3, a column 4, a swing arm 5, a roller assembly 6, a balancer 7, a cylinder 8, a sleeve inserting and withdrawing tool 9, and a hydraulic oil station 10.
[0037] The track 1 is arranged parallel to the hook body 13 inspection line, such as Figure 6-7 The double-dotted line in the figure is the maintenance line of the hook body 13, which can be close together or leave a pedestrian passage in the middle. The present embodiment belongs to the latter, and the operator can walk between the maintenance line of the hook body 13 and the track 1.
[0038] A moving trolley 2 is arranged on the track 1 , and the moving trolley 2 is provided with a driving mechanism 3 , which can drive the moving trolley 2 to move along the length direction of the track 1 .
[0039] A vertically upward column 4 is fixedly provided on the mobile trolley 2, and a swing arm 5 is rotatably provided on the column 4. The swing arm 5 is horizontal, which can ensure that the swing arm 5 can hover after swinging to the required angle, and will not be affected by gravity and rotate unconsciously. A limiting mechanism is provided between the swing arm 5 and the column 4, and the swing arm 5 can only swing within the limited angle. The angle of the swing arm 5 is generally determined according to the length of the swing arm 5 and the distance from the column 4 to the maintenance room, ensuring that within the limited angle, the end of the swing arm 5 does not leave the maintenance line. In this embodiment, the swing range of the swing arm 5 is ±40°, with the angle perpendicular to the guide rail direction being 0°. There is an angle sensor between the swing arm 5 and the column 4. There are mature products in the angle sensor market, and there are multiple installation structures, in which the housing is fixed on one of the column 4 or the swing arm 5, and the detection turntable is fixed on the other (not shown in the figure), which is used to detect the angle of the swing arm 5 in real time.
[0040] The swing arm 5 can be welded by I-beam or steel plate. A roller assembly 6 is slidably provided on the lower surface of the swing arm 5. The roller assembly 6 generally has 2 or 4 rollers, which are clamped on the wing plate of the I-beam on the left and right sides. The rollers are connected by brackets to enable the roller assembly 6 to slide freely on the swing arm 5.
[0041] A balancer 7 is provided below the roller assembly 6, and a cylinder 8 is suspended below the balancer 7, and a set-back tool 9 is installed on the cylinder 8. There are many options for the balancer 7, both pneumatic and spring types are available. This solution adopts a spring balancer 7, and by adjusting the main adjustment worm on the balancer 7, the balance weight of the balancer 7 and the weight of the cylinder 8 can be made consistent, so that the cylinder 8 can be balanced at any position within the travel range, even if the cylinder 8 is in a weightless state, which is convenient for operators to use and more labor-saving. The balancer 7 is usually also provided with a safety rope. When the balancer 7 is suspended, the safety rope needs to be connected in advance to ensure the safe use of the balancer 7.
[0042] The power of the oil cylinder 8 comes from the hydraulic oil station 10, which is fixed on the mobile trolley 2. The oil pipe between the hydraulic oil station 10 and the oil cylinder 8 is arranged along the balancer 7, the swing arm 5, and the column 4, and is suspended under the swing arm 5 through multiple pulley groups (not shown in the figure). When the roller assembly 6 moves to the end of the swing arm 5, the oil pipe is almost straightened. When the oil cylinder 8 moves to the root of the swing arm 5, it is suspended in a W shape for easy use.
[0043] In this embodiment, a wired controller can be provided on the mobile trolley 2, and the mobile trolley 2 can be controlled to move back and forth on the guide rail by pressing an operation button. In addition, the control can also be performed by the angle of the swing arm 5. The angle sensor detects the angle of the swing arm 5 in real time, for example Figure 7 As shown, when the swing arm 5 swings counterclockwise to the limit angle of -40°, it means that the oil cylinder 8 cannot reach the workpiece. At this time, the mobile trolley 2 moves to the left by itself. The operator usually holds the oil cylinder 8 with his hand and pushes the oil cylinder 8 to the left. When the oil cylinder 8 reaches the hook body 13 where the sleeve needs to be inserted and withdrawn, it will stop, and the mobile trolley 2 continues to move to the left. Therefore, the angle of the swing arm 5 will gradually decrease. When it reaches -20°, the mobile trolley 2 stops moving. Therefore, the movement of the mobile trolley 2 can be achieved without pressing a button, which improves the convenience of operation.
[0044] In practical applications, two sensors 11 are provided on the column 4. When the swing arm 5 swings to two extreme angles, the two sensors 11 are triggered respectively. The sensor 11 and the angle sensor are used together to avoid false signals and improve the accuracy of detection.
[0045] In practical applications, the sensor 11 includes one of the following: a photoelectric sensor, a Hall sensor, a proximity switch, and a travel switch. The sensor 11 selected in this embodiment is a slot-type photoelectric switch, which is installed on the side of the upper part of the column 4. A baffle 12 is connected below the swing arm 5. When the swing arm 5 swings to the limit angle, the baffle 12 will cover the slot-type photoelectric switch.
[0046] In practical applications, travel switches are installed at both ends of the track 1. When the moving trolley 2 moves to the limit travel, the travel switch can be triggered. When the travel switch is triggered, the moving trolley 2 stops moving, thereby improving safety.
[0047] In actual application, the trolley is rotatably provided with a plurality of axles 201, and in this embodiment, there are three axles 201. Wheels 202 are installed at both ends of the axles 201, and the wheels 202 can roll in the track 1. The driving mechanism 3 includes a reduction motor, and the reduction motor is installed above the trolley. The reduction motor and one of the axles 201 are connected through a sprocket chain. The trolley is provided with a bar hole for the chain to pass through, so the reduction motor rotates, and one of the axles 201 is driven to rotate through the chain sprocket. There are six wheels 202, two of which are driving wheels and four are driven wheels, thereby realizing the moving function of the mobile trolley 2.
[0048] In actual application, two parallel vertical plates 203 are fixedly installed on the mobile trolley 2, and a top plate 204 is fixedly installed on the top of the two vertical plates 203. The vertical plates 203 and the top plate 204 constitute a door-shaped frame, the driving mechanism 3 is arranged in the door-shaped frame, and the column 4 is installed on the door-shaped frame. The driving mechanism 3 is arranged in the door-shaped frame to improve the aesthetics and facilitate maintenance.
[0049] To sum up, the utility model has a wide working coverage range and a high fault tolerance rate, and meets the working requirements of the production line. The utility model automatically controls the movement of the mobile cart 2 through the angle, so the operator can realize the movement of the mobile cart 2 only by pushing the rocker arm, without pressing the button, thereby improving the convenience of operation.
[0050] The above shows and describes the basic principles, main features and advantages of the utility model. The technicians in this industry should understand that the above implementation is only to illustrate the technical concept and characteristics of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it, and it cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
