The housing unit 3 may be arranged in the vicinity of a joystick 10 (mechanical joystick) of a remote actuator such as a crane, the joystick 10 being located outside the housing unit 3 and connected to the actuator. The solenoid valve unit 1 is provided in the case unit 3 and electrically connected to the actuator.
The far-end actuator is a near-end actuator that is closer to the operator and a far-end actuator that is farther from the operator.
An operator inputs an instruction to the handheld remote controller 9, the handheld remote controller 9 sends the instruction to the wireless receiving controller 8, and the wireless receiving controller 8 controls the pneumatic electromagnetic valve unit 1 to act so as to enable the executing mechanism to perform telescopic operation, so that the operating rod 10 is driven to switch between different operating positions. For example, the joystick 10 is switched from the "middle position" shown in fig. 3 to the "rear position" or from the "middle position" shown in fig. 1 to the "front position", etc., thereby realizing remote control of the joystick 10. Therefore the utility model discloses a remote control unit's application can increase operating personnel's manipulation field of vision scope, improves and controls environment and fatigue strength. Therefore the utility model discloses a remote control unit can be used for but not limiting to crane, excavator, bull-dozer etc. have the environment that mechanical operation pole manipulation demand to realize that operating personnel keeps away from the function of crane and remote operation crane operation.

In the preferred embodiment, the actuator is a cylinder actuator 7. An operator inputs an instruction to the handheld remote controller 9, the handheld remote controller 9 sends the instruction to the wireless receiving controller 8, and the wireless receiving controller 8 controls the electromagnetic valve unit 1 to act so as to enable the executing mechanism to perform telescopic operation, so that the operating rod 10 is driven to switch between different operating positions. For example, the joystick 10 is switched from the "middle position" shown in fig. 3 to the "rear position" or from the "middle position" shown in fig. 1 to the "front position", etc., thereby realizing remote control of the joystick 10. Therefore the utility model discloses a remote control unit's application can increase operating personnel's manipulation field of vision scope, improves and controls environment and fatigue strength.
By adopting the cylinder actuating mechanism 7 for driving, the electric push rod unit has the following advantages compared with the existing electric push rod unit: on one hand, under the condition that the stroke of the actuating mechanism 7 is larger than the one-way push-pull stroke of the operating rod 10, the air cylinder is not easy to be damaged due to the compressibility of air, and the electric push rod is driven by an internal motor, so that the possibility of motor burning exists when the motor is locked, and the practicability and reliability of the electric push rod are improved; on the other hand, the actuation time of the cylinder is relatively fast, and therefore the sensitivity of the actuation of the joystick 10 can be increased.
The cylinder actuator 7 will be described in detail below.
First, the cylinder actuator 7 in the present embodiment has a modular feature. Specifically, the number of the cylinder actuators 7 is at least one, so that the cylinder actuators 7 can be used in a single group or multiple groups, thereby correspondingly realizing remote control operation of a single operating rod or multiple operating rods. In the embodiment shown in fig. 1, the number of cylinder actuators 7 is 3.
The cylinder actuator 7 includes a cylinder 701, a cylinder holder 702, and a cylinder piston rod 703. As shown in fig. 2b and 3, a first end of the cylinder rod 703 is connected to an end plate 704 located outside the housing unit 3, the end plate 704 is connected to the operating lever 10 via the locking clip unit 6, and a second end of the cylinder rod 703 is disposed in the cylinder 701. The cylinder 701 is fixed in the case unit 3 by a cylinder fixing base 702.
Wherein the end connection plate 704 is arranged on the middle bracket 5 outside the box body.
The locking clip 601 unit 6 includes a knuckle bearing 602 and a clip 601. The second end of the knuckle bearing 602 (the fisheye joint portion) is hinged to the first end of the end connection plate 704. As shown in fig. 3, the second end of the spherical bearing 602 and the first end of the end connection plate 704 form a spherical hinge pair, which can avoid dead spots on the structure after the mounting.
The clamp 601 is used for being fixedly connected with the operating rod 10, and the clamp 601 is fixedly connected with the first end of the knuckle bearing 602 through a screw rod.
That is, the end connecting plate 704, the spherical plain bearing 602, and the yoke 601 are connected in this order, and the end of the end connecting plate 704 remote from the yoke 601 is connected to the first end of the cylinder piston rod 703. When the cylinder piston rod 703 extends out, the hoop 601 is pushed and the operating lever 10 fixed to the hoop 601 is driven to move to the 'forward' position; on the contrary, when the cylinder rod 703 retracts, the clamp 601 is pulled and the operating lever 10 fixed to the clamp 601 is driven to move to the "rear position", and when the cylinder rod 703 does not have power, the operating lever 10 returns to the "middle position" under the self-resetting action of the operating lever 10.
Therefore, when the clamp 601 is locked with the operating lever 10, the actuator 7 can realize the fixed axis swinging motion of the operating lever 10 within the angle range theta shown in fig. 3.
Further, the clamp 601 is of a one-side opening and closing structure, so that quick clamping is facilitated.
As shown in fig. 1 and 2b, the middle bracket 5 comprises a support rod 503, a draw hook 502 and a support tube 501. The strut 503 is disposed outside the case unit 3, and has a substantially U-shaped configuration, and both ends of the strut are fitted with the support tubes 501, and the end connecting plate 704 is disposed on the strut 503. The leg 501 abuts on the outer side wall of the case unit 3. One end of the draw hook 502 is connected with the side wall of the box body unit 3, the other end of the draw hook is connected with a support rod 503, and the support rod 503 enables the cylinder piston rod 703 to be kept horizontal under the constraint of the draw hook.
Since the end connecting plate 704 is disposed on the supporting rod 503, the connecting height between the cylinder piston rod 703 and the operating lever 10 can be easily and quickly determined by the supporting rod 503.
When the deployment is performed, the operating rod 10 is firstly placed at the "neutral" position shown in fig. 3, the rod 503 is hooked by the hook 502 so that the cylinder rod 703 is approximately horizontal, and the clamp 601 is fixedly connected with the operating rod 10 at the height position. Before operation, the draw hook 502 releases the supporting rod 503, then the supporting rod 503 naturally sags, and the maximum extending stroke of the cylinder piston rod 703 is not less than the formation of the limit position reached by the operating rod 100 (i.e. the forward pushing or backward pulling stroke) by manually pushing the operating rod 100 to the 'forward position' and properly adjusting the fixed position of the clamp 601 on the operating rod 100.
The electromagnetic valve unit 1 is connected with an air inlet and an air outlet of the air cylinder 701 through an air pipe. The execution unit further includes a terminal block 2 disposed at the right rear side in the case unit 3, and the solenoid valve unit 1 is electrically connected to the wireless reception controller 8 through the terminal block 2. The lines of the electromagnetic valve unit 1 are converged at the terminal block 2 and then sequentially shunted to the wireless receiving controller 8, so that the neatness of wiring is ensured.
Specifically, the electromagnetic valve unit 1 is a middle-leakage three-position five-way electromagnetic valve, and the operating principle of the electromagnetic valve unit is that when the middle-leakage three-position five-way electromagnetic valve is powered on, the cylinder piston rod 703 extends or retracts, and when the middle-leakage three-position five-way electromagnetic valve is powered off, the valve body is conducted with the atmosphere, so that the cylinder piston rod 703 returns to the middle position, and the cylinder piston rod 703 stays and switches at three positions, namely a "front position", a "middle position" and a "rear position".
In addition, as described above, the joystick 10 itself has a neutral position resetting capability, and in combination with the characteristics of the cylinder rod 703, the three positions of "push forward", "neutral position" and "pull back" of the mechanical joystick 10 can be indirectly stopped.
The middle-leakage three-position five-way electromagnetic valve is also connected with the wireless receiving controller 8, and the on-off of a digital quantity switch in the wireless receiving controller 9 is controlled through a remote control signal of the handheld remote controller 9, so that the power on and the power off of the middle-leakage three-position five-way electromagnetic valve are controlled, and the action of the control rod 10 of the cylinder piston rod 703 is realized.
The box unit 3 is provided with a supporting bent plate 303, and the cylinder 701 and the wireless receiving controller 8 are respectively positioned at the upper side and the lower side of the supporting bent plate 303, so that the overall layout space of the box is reduced.
The maximum stroke of the cylinder piston rod 703 is not less than the stroke of the operating lever to the limit position.
The bottom of the box body unit 3 is provided with a magnetic base, and the box body unit 3 is fixedly connected with the steel plate magnetic adsorption on the ground through the magnetic base (manual magnetic base). By rotating the magnetic base, the box body unit 3 and the ground steel plate can be fixed in a strong magnetic adsorption mode. The number of the magnetic force seats can be 2 or more than 2.
The back side of the box body unit 3 is provided with a power socket 304, an air pipe socket 305 and a power indicator lamp 302 which are respectively electrically connected with the execution unit; after the power supply socket 304 and the air pipe socket 305 are respectively connected with the power supply and the air supply, the indicator light 302 is on.
The front side of the box unit 3 is provided with a box handle 306, and the upper end of the box unit 3 is provided with a box door 301.
Since the box unit 3 accommodates various mechanisms and components such as the wireless receiving controller 8, the actuator, the solenoid valve unit 1, the terminal block, and the like, rapid deployment of the remote control device and easy disassembly and assembly are facilitated.
The following describes in detail the method of use of the present invention, taking the cylinder actuator 7 as an example.
The human operator operates the hand-held remote controller 9 at a position remote from the joystick 10. As shown in fig. 1, the handheld remote control 9 is provided with buttons such as "1 extend", "2 extend", "3 extend", "standby 1", "1 return", "2 return", "3 return", and "standby 2".
When an operator presses the button "1 stretch", one of the cylinder actuators 7 in communication with the operator operates, specifically, the cylinder piston rod 703 performs a stretching operation; an end connecting plate 704 on the cylinder piston rod 703 drives the operating lever 10 to perform a forward motion through a hoop 601, so that the forward motion of the operating lever 10 is realized. When an operator releases the '1-extension' button, the wireless receiving controller 8 controls the relay to be powered off, the electromagnetic valve unit 1 is powered off and is located at the middle leakage position, and the cylinder piston rod 703 returns to the middle position under the self-resetting action of the operating rod 10.
When an operator presses the button "1 go back", the electromagnetic valve unit 1 is powered on and reverses, the cylinder piston rod 703 executes retraction, and the end connecting plate 704 on the cylinder piston rod 703 drives the operating lever 10 to execute "back position" action through the hoop 601, so that the operating lever 10 is pulled back. When the button "1 return" is released, the electromagnetic valve unit 1 is powered off under the action of the wireless receiving controller 8, the electromagnetic valve unit 1 stays at the middle leakage position again, and the cylinder piston rod 703 and the operating rod 10 both return to the middle position.
In the above operation, the joystick 10 switches the three positions according to the jog command from the hand-held remote controller 9, and indirectly controls the operation of the remote actuator connected to the joystick 10. For example, in crane lifting work, the motions of raising, lowering, extending, and rotating the boom of the crane arm can be indirectly controlled.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. The present invention is not limited to the particular embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
