Description

Technical Field

[0001] The utility model relates to a clutch device, in particular to a clutch combination device used for a heavy-load mobile vehicle. Background Art

[0002] Some of the current mobile carts are designed to carry a large load, so they need a high-power motor to drive them. Since the high-power motor is large in size and weight, the inertia generated when it is installed in combination with the cart is relatively large. When the mobile cart is empty, it must also move with the high-power motor, which causes great safety risks and energy consumption. In order to ensure work safety, the speed of these mobile carts when moving on the track is generally controlled very slowly, resulting in low efficiency of the mobile cart and inability to adapt to various working conditions. Summary of the invention

[0003] The utility model provides a clutch combination device for a heavy-load mobile vehicle, which can realize the combination and separation of a driving shaft and a motor so as to adapt to different working states.

[0004] The utility model adopts the following technologies: a clutch combination device for a large-load mobile trolley, which mainly includes a clutch body, a toggle device and a position locking assembly. The clutch body is sleeved on the main transmission shaft of the mobile trolley and is connected with the main transmission shaft. The clutch body can move axially on the main transmission shaft. The driving gear connected to the output end of the mobile trolley driving motor is opposite to one end of the clutch body. A toggle device is provided on the clutch body. A position locking device is provided between the toggle device and the main body of the mobile trolley. The toggle device toggle the clutch body so that the clutch combination tooth at one end of the clutch body is fixed with the transmission tooth provided on the end face of the driving gear. The teeth are engaged or disengaged. When the mobile trolley needs to be driven by the driving motor, the toggle device toggles the clutch body so that the clutch engaging teeth are engaged with the transmission teeth. The meshing state between the clutch engaging teeth and the transmission teeth is locked by the position locking device. The driving motor drives the main transmission shaft to rotate through the meshing of the transmission teeth of the driving gear and the clutch body. The main transmission shaft drives the traveling wheels of the mobile trolley to move on the track. When the mobile trolley needs to move quickly on the track alone, the position locking device is opened, and the toggle device toggles the clutch body so that the clutch engaging teeth are separated from the transmission teeth, thereby realizing the separation of the driving motor and the main transmission shaft.

[0005] Furthermore, the toggle device mainly includes a control arm, one end of which is rotatably connected to the moving trolley through a pin shaft, and the other end of the control arm is set as an operating section. A toggle slider is fixedly installed on the main body of the control arm, and the toggle slider is correspondingly embedded in the guide groove on the surface of the clutch body. After the toggle operating section causes the control arm to rotate around the pin shaft, the clutch body is driven axially by the toggle slider, and when the main transmission shaft of the moving trolley rotates, a sliding fit is formed between the guide groove and the toggle slider.

[0006] Furthermore, the position locking device mainly includes a mounting bracket parallel to the clutch body, one end of the mounting bracket is connected to the moving trolley, a limit hole is provided on the mounting bracket, and an indexing pin is provided in the mounting hole of the control arm. The indexing pin corresponds to the limit hole when the clutch engaging teeth and the transmission teeth are engaged. When the clutch engaging teeth are engaged with the transmission teeth, the indexing pin is tightened downward, and the indexing pin passes through the mounting hole and the corresponding limit hole and is locked, so that the control arm is connected to the mounting bracket. When the clutch engaging teeth need to be separated from the transmission teeth, the indexing pin is unscrewed upward, the control arm is separated from the mounting bracket, and the control arm drives the clutch engaging teeth to separate from the transmission teeth.

[0007] Furthermore, the inner hole of the clutch body is provided with axial slide grooves, and the surface of the main transmission shaft is provided with axial guide keys. After the clutch body is sleeved on the main transmission shaft, a connection is formed between the guide keys and the slide grooves, and the clutch body forms axial sliding on the main transmission shaft through the guide keys and the slide grooves.

[0008] Furthermore, the transmission teeth are configured as gear step teeth.

[0009] The utility model has the following beneficial effects: after adopting the above technical scheme, the utility model adopts a toggle device to toggle the clutch body so that the clutch combining teeth are meshed with the transmission teeth, and the meshing state between the clutch combining teeth and the transmission teeth is locked by the position locking device, and the driving motor drives the main transmission shaft to rotate through the meshing of the transmission teeth of the driving gear and the clutch body, and the main transmission shaft drives the walking wheels of the mobile trolley to move on the track. When the mobile trolley needs to move quickly on the track alone, the position locking device is opened, and the toggle device toggle the clutch body so that the clutch combining teeth are separated from the transmission teeth, so as to realize the rapid separation of the driving motor and the main transmission shaft, that is, the rapid separation of the driving shaft of the mobile trolley and the motor is realized, so that the trolley can be moved quickly by dragging very conveniently, and when the mobile trolley is unloaded, it is convenient for the trolley to quickly enter and leave the working area, so as to adapt to different working states, so as to ensure the safety under various working states, and at the same time, because the mobile trolley can be moved quickly without starting the mobile trolley in the unloaded state, energy consumption is greatly saved. The toggle device and position locking device adopted by the present invention are not only simple in structure, but also can conveniently control and lock the clutch body.
