Description

Technical Field

[0001] The utility model relates to the technical field of ship loaders, in particular to a ship loader conveyor belt tensioning force detection and adjustment mechanism. Background Art

[0002] See also Figure 1 , 2 , is a schematic diagram of the tensioning structure of the conveyor belt of the existing ship loader, a first fixed roller 2 is installed on the upper side of the frame 1 of the ship loader, a second fixed roller 3 is installed on the lower side of the frame 1, and a tensioning roller 4 is installed on the frame 1 between the first fixed roller 2 and the second fixed roller 3 through a square bearing seat 5, and the conveyor belt passes around the first fixed roller 2, the tensioning roller 4 and the second fixed roller 3. The frame 1 is provided with a slide groove 11 on the upper and lower sides of the bearing seat 5, and the bearing seat 5 can slide along the slide groove 11. At present, the tensioning of the conveyor belt is achieved by respectively pushing the two bearing seats 5 with two screws 6 screwed on the frame 1. During adjustment, since the screw rods 6 on both sides are adjusted separately, it is impossible to control the adjustment force of the screw rods 6 on both sides well. After adjustment, the conveyor belt may deviate easily. Each time the tension is tightened, workers need to squat for a long time to adjust repeatedly, which makes the tension adjustment inconvenient. Moreover, since the tension force cannot be detected, it is impossible to ensure that the conveyor belt works under the appropriate tension force. The conveyor belt may slip easily if the tension force is small, and the conveyor belt may be damaged easily if the tension force is too large. Utility Model Content

DETAILED DESCRIPTION

[0021] like Figure 3-5 As shown, a tension detection and adjustment mechanism for the conveyor belt of a ship loader comprises a tensioning roller 4, which is movably and adjustably mounted on a frame 1 through a bearing seat 5, and a tensioning device 8 is mounted on the frame 1, and the tensioning device 8 pushes the tensioning roller 4 to tension the conveyor belt of the ship loader; a pushing beam 7 is mounted on the bearing seat 5 on both sides near the tensioning device, and a connecting seat 82 is mounted on the pushing beam 7, and an insertion hole 821 is arranged at one end of the connecting seat 82 near the tensioning device 8, and a pressure sensor 9 is also mounted at the end, and an insertion section 811 is arranged at the end of the telescopic rod 81 of the tensioning device 8, and the insertion section 811 passes through the pressure sensor 9 and is inserted into the insertion hole 821 of the connecting seat 82, and the end of the telescopic rod 81 abuts against the pressure sensor 9. The pushing beam 7 is pushed by the tensioning device 8, and the pushing beam 7 pushes the bearing seats 5 on both sides to move, thereby pushing the tensioning roller 4 to move to the left, so as to tension the conveyor belt. No manual tensioning is required, and the tensioning adjustment is convenient. In addition, through the pressure sensor 9, the tensioning force can be detected when the conveyor belt is tensioned, so that the conveyor belt can run under the rated tensioning force.

[0022] Specifically, the pressure sensor 9 is a through-type force sensor of model BSHT-2. During installation, the pressure sensor 9 is electrically connected to a force value display controller, and the force value display controller is used to display the tension force detected by the pressure sensor 9.

[0023] Furthermore, the connecting seat 82 is provided with a first long hole 822, the insertion section 811 of the telescopic rod 81 is provided with a limiting hole 812, and the first pin 83 penetrates the first long hole 822 and the limiting hole 812 to limit the connecting seat 82 and the telescopic rod 81. The first long hole 822 is provided on the connecting seat 82, so that the connecting seat 82 and the telescopic rod 81 can be connected through the first pin 83 without affecting the measurement of the pressure sensor 9. And the tensioning device 8 can not only push the tensioning roller 4, but also facilitate the tensioning roller 4 to be pulled out. For details, see Figure 5 , the end of the insertion section 811 does not abut against the bottom of the insertion hole 821 .

[0024] See also Figure 4 Two connecting seats 82 are installed on the push beam 7, and two tensioning devices 8 are installed on the frame 1. The telescopic rods 81 of the two tensioning devices 8 are installed and connected with the two connecting seats 82 respectively.

[0025] See also Figure 3-5 The bearing seats 5 on both sides are provided with notches 51 on the side close to the tensioning device, and the bearing seats 5 are provided with positioning holes at the positions of the notches 51. The two ends of the push beam 7 are provided with second long holes 71, and the two ends of the push beam 7 are respectively installed in the notches 51 of the bearing seats 5 on both sides. The pivot 72 passes through the positioning holes on the bearing seats 5 and the second long holes 71 on the push beam 7, so that the push beam 7 and the bearing seats 5 can swing at a certain angle. The push beam 7 is provided with a first hinge seat 73 at the telescopic rod 81 corresponding to the tensioning device, and the connecting seat 82 is provided with a second hinge seat 823 at the end away from the tensioning device 8. The first hinge seat 73 and the second hinge seat 823 are installed in coordination and are hinged by a hinge pin 84. Through the above structure, the two tensioning devices 8 can be started at the same time to push the tensioning roller 4 for translation and tensioning, and the two tensioning devices 8 can be started separately as needed to push the tensioning roller 4 separately, so that the tensioning force at both ends of the tensioning roller 4 can be adjusted separately. In this process, the bearing seat 5 is limited and slidable by the slide groove 11 on the frame 1, see Figure 3 , 4 The bearing seat 5 can only slide in a directional manner left and right, and the two ends of the push beam 7 are hinged to the bearing seats 5 on both sides through the second long holes 71, so that the bearing seats 5 on both sides can independently swing forward and backward for a certain distance. Figure 5 The pushing beam 7 is hinged to the second hinge seat 823 of the connecting seat 82 through the first hinge seat 73, so that the two tensioning devices 8 can push the pushing beam 7 independently.

[0026] Preferably, the tensioning device 8 is a SWL screw screw elevator. Specifically, each screw screw elevator has its own motor.

[0027] In another preferred solution, the tensioning device 8 is an electric push rod.

[0028] The working principle of this utility model:

[0029] When using, see Figure 4 , the two tensioning devices 8 are started synchronously, and the telescopic rods 81 of the two tensioning devices 8 are extended synchronously, so that the tensioning roller 4 can be pushed to the left in translation, see Figure 3 The structure in the conveyor belt is tightened.

[0030] When the pressure sensors 9 on both sides detect that the tensioning forces of the tensioning devices 8 on both sides are inconsistent, the tensioning devices 8 can be individually controlled to start by jogging them separately, so as to adjust the tensioning forces on both sides to be consistent.

[0031] By detecting the tension force through the pressure sensor 9, the value of the tension force can be observed intuitively, so that the size of the tension force can be guaranteed during adjustment, so that the conveyor belt can run under the rated tension force.
