Description

Technical Field

[0001] The utility model relates to a coupler installation device, in particular to a hydraulic coupler installation device, belonging to the technical field of hydraulic couplers. Background Art

[0002] Belt conveyors are widely used to transport bulk materials. Belt conveyor motors are generally non-variable frequency motors. During the startup process, the actual motor speed increases, which does not meet the actual use requirements. Therefore, the belt conveyor drive motor is generally used in conjunction with a hydraulic coupler to achieve soft start of the belt conveyor and protect the motor and other related equipment during the startup process. At the same time, the presence of the hydraulic coupler can ensure the safe operation of the motor during the operation. For example, when large material heads or excessive belt conveyors occur during operation, the motor will be overloaded. The presence of the coupler can effectively protect the motor from overload.

[0003] The design life of the belt conveyor coupler components is generally lower than that of the reducer, drive motor and other equipment. Therefore, damaged and aged couplers should be replaced regularly during use. However, the coupler and the motor are installed with interference fit, and the installation accuracy is high. At the same time, the motor output shaft and the coupler connection shaft are non-heatable devices. Based on this, it is necessary to design a belt conveyor coupler installation device to achieve efficient separation of the coupler and motor connection without heating. Utility Model Content

[0020] An embodiment of the utility model provides a hydraulic coupler installation device.

[0021] See also Figure 1 , Figure 2 and Figure 3 , including a motor 1, a hydraulic coupling 2 is arranged outside the motor 1, the motor 1 and the hydraulic coupling 2 are both prior arts, and will not be described in detail in this application. The output shaft of the motor 1 must be pre-installed on the hydraulic coupling 2 in advance, and the hydraulic coupling 2 is lifted by a crane and lifted to a designated position for pre-assembly with the output shaft of the motor 1, which ensures that the mounting hole of the hydraulic coupling 2 is concentric with the output shaft of the motor 1 to a certain extent.

[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A set of coupler claws 3 are fixedly connected to the outer surface of the hydraulic coupler 2. During the installation process, it is necessary to avoid the motor 1 shaking left and right and front and back during the installation of the hydraulic coupler 2 to ensure a stable connection between the hydraulic coupler 2 and the motor 1.

[0023] A fixed disk 4 is provided on the outside of the hydraulic coupler 2. The fixed disk 4 adopts a thin plate circular design. During use, the lead screw 5 needs to be used in conjunction with the fixed disk 4 and pre-installed to a certain position. During installation, the axis of the vertical motor 1 is installed in conjunction with the coupler claw 3 to fix the fixed disk 4. In order to increase the contact area between the coupler claw 3 and the fixed claw 9, a group of claw stops are designed on each fixed claw 9.

[0024] See also Figure 1 and Figure 2 A group of weight-reducing holes 7 are provided on the outer surface of the fixing plate 4. The arrangement of the plurality of weight-reducing holes 7 can effectively reduce the weight of the claws, making it convenient for maintenance personnel to inspect and repair the device.

[0025] A fixture assembly hole 8 is opened in the middle of the fixing plate 4. Through the setting of the fixture assembly hole 8, the fixture mechanism 6 and the fixing plate 4 can be fixed in one direction. By rotating the fixing plate 4, the fixture mechanism 6 and the axial position of the screw 5 can be changed, thereby realizing the installation of the hydraulic coupling 2.

[0026] A set of fixed claws 9 are fixedly connected to the outer surface of the fixed plate 4. The fixed claws 9 are adapted to the coupler claws 3. The fixed claws 9 can be adjusted according to the claws of different models of hydraulic couplers 2, and can be used together. The fixed claws 9 are designed with installation holes such as extension rods or crowbars, and the fixed plate 4 can be rotated by using extension rods or crowbars.

[0027] The output shaft of the motor 1 is threadedly connected with a screw 5, which is made of a material with high toughness. One end of the screw 5 is processed into a hexagonal head form, and the other end is processed into a certain taper form, which is convenient for installing the screw 5 in the center bolt hole of the output shaft of the motor 1. During the installation of the hydraulic coupler 2, an ordinary open-end wrench is used to rotate the screw 5. At the same time, through the mutual cooperation between the fixed plate 4 and the coupler claw 3, the hydraulic coupler 2 can be quickly and conveniently removed.

[0028] See also Figure 1 and Figure 3 A fixture mechanism 6 is provided on the outside of the screw 5, and the fixture mechanism 6 includes a fixture baffle 12. During the installation process, the fixture mechanism 6 of the device must be pre-installed with the screw 5 in advance, and the fixture mechanism 6 is rotated to the specified position of the screw 5, and then the assembled fixture mechanism 6 is installed in conjunction with the installation fixing plate 4. Finally, the assembled hydraulic coupler 2 installation device is installed in the hydraulic coupler 2 card position through the screw 5, which facilitates the subsequent removal of the hydraulic coupler 2.

[0029] A fixing threaded hole 11 is provided inside the fixing baffle 12, and the fixing threaded hole 11 is threadedly connected to the lead screw 5. The fixing threaded hole 11 and the lead screw 5 adopt the same thread standard for mutual cooperation. First, the fixing mechanism 6 is installed with the lead screw 5 through the fixing threaded hole 11, and the fixing mechanism 6 is installed to the specified position of the lead screw 5 according to the distance between the end face of the hydraulic coupling 2 and the end face of the output shaft of the motor 1, and then the fixing mechanism 6 on the lead screw 5 is installed with the fixing plate 4.

[0030] The outer surface of the fixer baffle 12 is fixedly connected with a fixer claw 10, and the fixer assembly hole 8 is adapted to the fixer claw 10. The fixer claw 10 can be engaged with the fixer assembly hole 8, so as to facilitate the assembly of the fixing plate 4 and the fixer mechanism 6 together. During installation, the fixing claw 9 of the fixing plate 4 is installed in conjunction with the fixer assembly hole 8, and the hydraulic coupling 2 installation device is assembled for later use.

[0031] See also Figure 4 The inner wall of the hydraulic coupling 2 is fixedly connected with a turbine 13 and a pump wheel 14, respectively. A guide wheel 15 is arranged inside the hydraulic coupling 2. The turbine 13, the pump wheel 14 and the guide wheel 15 are all prior arts and will not be described in detail in this application. The turbine 13 and the pump wheel 14 are semicircular rings with many blades arranged radially. They are coupled and arranged facing each other without contacting each other. There is a gap of a certain width in the middle to form a circular working wheel. The guide wheel 15 can guide the liquid and increase the torque of the coupler.

[0032] The turbine 13 and the pump wheel 14 are both engaged with the guide wheel 15. Sufficient hydraulic oil is delivered to the interior of the hydraulic coupling 2 through the oil delivery port 16. When the pump wheel 14 rotates, the blades drive the oil. Under the action of centrifugal force, the oil is thrown to the edge of the pump wheel 14 blades and impacts the turbine 13 blades, causing the turbine 13 to start rotating. Under the action of inertia, the oil rushing to the turbine 13 enters the inner edge of the turbine 13 and returns to the inner edge of the pump wheel 14, and this cycle repeats itself, thereby transmitting the power of the motor 1 to the working machine.

[0033] Two oil delivery ports 16 are provided on the outer surface of the hydraulic coupling 2, and the two oil delivery ports 16 are respectively connected to an oil inlet pipe and an oil outlet pipe. Through the setting of the two oil delivery ports 16, the hydraulic oil can be delivered to the inside of the hydraulic coupling 2 or extracted from the inside of the hydraulic coupling 2, so as to facilitate the reuse of the hydraulic oil.
