Description

Technical Field

[0001] The invention relates to environmental monitoring equipment, and in particular to an automatic replacement device for a cutter. Background Art

[0002] At present, the particle sampling heads of the particle monitoring equipment of most environmental monitoring stations need to be replaced and cleaned and maintained manually on a regular basis. Due to the limitations of manual regular operation and maintenance, each replacement of the sampling head requires a lot of manpower and time. At the same time, manual airtightness monitoring is required after the replacement, which affects the consistency and accuracy of environmental monitoring data. To achieve the replacement of the sampling head, the existing device usually installs a manipulator next to each sampling head for replacement. Not only can it not achieve long-term and stable automatic replacement of the sampling head, but the maintenance of the manipulator is also a large project. Moreover, when the number of sampling heads is large and relatively scattered, to achieve the automatic replacement of all the sampling heads, the cost and workload of personnel maintenance will increase significantly. Therefore, an automatic replacement device with simple structure, low maintenance cost, long-term adaptability, large sampling area and low cost is needed. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an automatic cutter replacement device, which can realize the automatic matching and separation between the sampling head and the sampling tube in a long-term and stable manner, can reduce the equipment installation cost and maintenance cost, and adapt to the environment with a large sampling area.

[0005] The sliding clamping system consists of a mechanical claw, a sliding frame, and a telescopic rod assembly. The sliding frame is electrically connected to the power supply track, the telescopic rod assembly is installed on the sliding frame, and the mechanical claw is installed on the telescopic rod assembly.

[0008] A sampling head outlet is provided on the bin body, and a lifting mechanism is arranged below the sampling head outlet;

[0009] The transmission mechanism is composed of a transmission plate and a rotating assembly. The transmission plate is installed on the rotating assembly and driven to rotate by the rotating assembly. A semicircular notch is respectively provided at both ends of the transmission plate. A gasket is provided on the arc edge of the semicircular notch. The two transmission plates are connected end to end in rotation. The two semicircular notches are combined to form a fixed ring seat for placing the sampling head. When the fixed ring seat is located at the sampling head outlet, the fixed ring seat, the sampling head outlet, and the lifting mechanism are located on the same straight line.

[0010] The transmission plate is also provided with a bracket for supporting the sampling head, which is located on one side of the fixed ring seat. The cooperation between the sliding clamping system and the power supply track enables the replacement of more sampling heads in a larger range through a single manipulator, reducing the maintenance cost and the cost of the manipulator.

[0011] As a further optimization scheme of the present invention, the power supply track is composed of two parallel concave bases, the concave surfaces of the concave bases are opposite, the concave surfaces of the concave bases are provided with conductors, and the sliding frame is arranged between the two concave bases.

By providing the conductive pin with an elastic member, the problem of power failure caused by poor contact between the sliding frame and the power supply track is prevented.

[0015] According to a further optimized solution, the rotating assembly is composed of a chain belt and a rotating motor. The rotating motor drives the chain belt to rotate, and the chain belt drives the transmission plate to rotate.

[0020] Beneficial effects:

[0021] The fully automatic replacement device of the present invention, through the cooperation of the power supply track and the sliding clamping system, not only solves the problem of high cost caused by the need to separately install a manipulator for multiple sampling heads, but also solves the maintenance problem of the manipulator.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Example

[0032] like Figure 1The cutter automatic replacement device shown includes a sliding clamping system 1 for clamping a sampling head, a power supply rail 2, a clean bin 3 for storing the sampling head, and a recovery bin 4. The power supply rail 2 is laid on both sides of the sampling tube, and the sliding clamping system 1 is slidably installed on the power supply rail 2, and the travel passes over the sampling tube, the clean bin 3, and the recovery bin 4. The sliding clamping system 1 is powered by the power supply rail 2 to realize the movement of the sliding clamping system and the replacement of the sampling head at different positions.

[0033] The sliding clamping system 1 is composed of a mechanical claw 11, a sliding frame 12, and a telescopic rod assembly 13. The sliding frame 12 is electrically connected to the power supply track 2. A circuit is provided in the sliding frame 12 to realize power supply for the mechanical claw 11. In this embodiment, the sliding frame 12 uses a gantry. The telescopic rod assembly 13 is fixedly installed on the top of the sliding frame 12, and the mechanical claw 11 is installed on the telescopic rod assembly 13. The telescopic rod assembly 13 enables the mechanical claw 11 to clamp. When it is necessary to grab, the telescopic rod assembly 13 is extended to realize the in-place grabbing of the mechanical claw 11.

[0034] like Figure 2 As shown, the mechanical gripper 11 is composed of a driving part 111 and a clamping claw 112. The telescopic rod assembly 13 is connected to the driving part 111. The clamping claws are installed on opposite sides of the driving part 111 and are driven by the driving part 111 to move laterally and clamp. In this embodiment, the driving part is a cylinder. A buffer 113 is provided on the bottom surface of the driving part 111. A contact sensor is provided on the buffer 113. The contact sensor is electrically connected to the telescopic rod assembly 13. When the buffer contacts the sampling head, the telescopic rod stops extending and retracting to prevent the sampling head from being squeezed and damaged.

[0035] like Figure 5 As shown, the clean bin 3 is similar to a clip-type structure. After taking a sampling head, a new sampling head will be continuously sent out for replacement by the mechanical claw. In the clean bin, the material is only loaded on one side of the transmission mechanism to prevent the sampling head from falling due to rotation to the bottom. The clean bin 3 is composed of a bin body 31, a transmission mechanism, and a lifting mechanism 33. The transmission mechanism 32 and the lifting mechanism 33 are both installed in the bin body 31. The bin body 31 is provided with a sampling head outlet 311. The lifting mechanism 33 is arranged below the sampling head outlet 311. When the fixed ring seat 323 is located at the sampling head outlet 311, the fixed ring seat 323, the sampling head outlet 311, and the lifting mechanism 33 are located on the same straight line. The lifting mechanism 33 is also provided with a base that matches the sampling head. When the mechanical claw clamps the sampling head, the lifting mechanism 33 rises, sends the sampling head out of the sampling head outlet, and the mechanical claw clamps the sampling head 8. In this embodiment, the clean bin 3 and the recovery bin 4 have the same structure. In the recovery bin 4, after the sampling head is inserted into the base of the lifting mechanism 33, the lifting mechanism 33 will pull the sampling head into the bin body. After reaching a certain position, the sampling head will no longer descend, and the sampling head will be separated from the base of the lifting mechanism 33, and the transmission mechanism can continue to rotate.

[0036] The transmission mechanism is composed of a transmission plate 321 and a rotating assembly 322. The transmission plate 321 is mounted on the rotating assembly 322 and driven to rotate by the rotating assembly 322. In this embodiment, the rotating assembly 322 is composed of a chain belt and a rotating motor. The rotating motor drives the chain belt to rotate. The transmission plate is mounted on the chain belt and driven by the chain belt. Figure 3 , Figure 4 As shown, a semicircular notch is respectively provided at both ends of the transmission plate 321, and a gasket is provided on the arc edge of the semicircular notch. The two transmission plates 321 are connected end to end, and the two semicircular notches are combined to form a fixed ring seat 323 for placing the sampling head. After the sampling head is recovered, it is placed on the fixed ring seat 323, and the gasket can ensure that the fixed ring seat clamps the sampling head and does not slide. A bracket 324 for supporting the sampling head is also provided on the transmission plate 321. The bracket 324 is mainly used to prevent the sampling head from tilting when the transmission plate 321 rotates. The bracket 324 is located on both sides of the fixed ring seat 323 and on the side of the clamping position of the clamping claw to ensure that the clamping claw does not clamp the bracket 324 when clamping.

[0037] like Figure 6 As shown, the power supply track 2 is composed of two concave bases 21 arranged in parallel. When placed, the concave bases 21 are placed sideways to ensure that the concave surfaces of the concave bases 21 face each other. The concave surfaces of the concave bases 21 are provided with a conductor 211. The sliding frame 12 is arranged between the two concave bases 21. The interior of the sliding frame 12 is provided with a circuit. The four feet of the sliding frame 12 are provided with pulleys 131. The pulleys are driven to slide by a motor. The side of the pulley 131 is provided with a conductive needle 132 that matches the conductor 211 and is located above the pulley 131. Figure 7 As shown, the conductive pin 132 is fixed to the sliding frame 12 through the elastic member 133 and is connected to the internal circuit of the sliding frame. The elastic member can ensure the contact between the conductive pin and the conductor to prevent the problem of poor contact. In order to ensure the safety of personnel, the power supply track 2 and the sliding frame are both insulated. In order to prevent rainwater from affecting the circuit, the bottom surface of the concave base 21 will be relatively thick to prevent water accumulation.

[0038] The power supply track 2 can be configured as a track connected end to end, and several sliding frames can be arranged on the power supply track to speed up the replacement of the sampling head in a larger area.

[0039] During operation, the power supply track 2 is energized. When the sampling head at a certain position needs to be replaced, the sliding frame slides to the specified position. After being positioned by the sensor, the telescopic rod extends, and the mechanical claw 11 is sent to the clamping position. The driving unit 111 drives the clamp to operate. After clamping the sampling head, the telescopic rod begins to recover and separate the sampling head from the pipeline. After separation, the sliding frame operates and sends the sampling head to the recovery bin. The lifting mechanism 33 in the recovery bin descends and retracts the sampling head into the recovery bin. The rotating assembly drives the transmission plate to rotate and retracts the sampling head to the side, waiting for the next sampling head. Then the sliding frame moves to the top of the clean bin. The clean bin detects the mechanical claw, and the rotating assembly rotates. When the sampling head is located above the lifting mechanism, the lifting mechanism 33 rises and sends the new sampling head for the clamp to clamp. After clamping, the sliding frame moves to the replacement position and reinstalls the sampling head. The sampling head replacement is completed.

Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents for which protection is sought in the present invention have been fully recorded in the claims.
