DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0045] The drawings will be described below in conjunction with the Figures 1 to 10 The present application will be further described in detail.

[0046] The embodiments of the present application disclose a track moving type sampling machine.

[0047] Reference Figures 1 to 10 A track moving type sampling machine comprises a swing arm mechanism, a walking mechanism and a sampling tube. The swing arm mechanism comprises a swing arm seat 4 and a swing arm hinged to the swing arm seat 4. A power assembly is arranged on the swing arm seat 4, and the power assembly is used to drive the swing arm to swing up and down. The walking mechanism comprises a track base 18 and a sliding seat 13 slidingly arranged on the track base 18. The swing arm seat 4 is rotationally arranged on the sliding seat 13.

[0048] The swing arm mechanism comprises a swing arm, a swing arm base 4, and a power assembly.

[0049] The swing arm comprises an upper swing arm 1, a lower swing arm 2, and a connecting rod 3. One end of the upper swing arm 1 is hingedly connected to the swing arm base 4, and one end of the lower swing arm 2 is hingedly connected to the swing arm base 4 near the end. The upper and lower ends of the connecting rod 3 are hingedly connected to the other end of the upper swing arm 1 and the lower swing arm 2, respectively. The upper swing arm 1, the lower swing arm 2, the connecting rod 3, and the swing arm base 4 form a parallel four-bar linkage structure. The sampling tube 30 is vertically arranged on the connecting rod 3. Through the parallel four-bar linkage structure, the angle of the connecting rod 3 does not change no matter how the swing arm swings, thereby ensuring that the sampling tube 30 always maintains a vertical state.

[0050] The power assembly comprises a power element A5. A pull rod base 6 is movably arranged on the swing arm base 4. The pull rod base 6 is located below the lower swing arm 2. One end of the pull rod base 6 is hingedly connected to the pull rod 7, and the other end of the pull rod 7 is hingedly connected to one end of the lower swing arm 2. The power element A5 drives the pull rod base 6 to move. Through the movement of the power element A5, the pull rod 7 hingedly connected to the pull rod base 6 can be driven to move, so that the pull rod 7 pulls or pushes the lower swing arm 2, thereby realizing the swinging of the lower swing arm 2 on the swing arm base 4.

[0051] The swing arm base 4 is provided with a sliding rail A8, and the bottom of the pull rod base 6 is provided with a sliding block A9. The pull rod base 6 is slidably connected to the sliding rail A8 through the sliding block A9. A lead screw 10 is arranged on the swing arm base 4 in the same direction as the sliding rail A8. The power element A5 can be a motor reducer set. The motor reducer set drives the lead screw 10 to rotate. The bottom of the pull rod base 6 is provided with a lead screw sleeve. The lead screw 10 is threadedly connected to the lead screw sleeve. The pull rod base 6 is slidably arranged on the swing arm base 4 through the sliding block A9 and the sliding rail A8. This sliding connection method is simple and reliable. The sliding of the pull rod base 6 is realized through the thread connection between the lead screw 10 and the lead screw sleeve. This control method is stable and accurate. The thread connection between the lead screw 10 and the lead screw sleeve has a locking function. When there is no power or the motor reducer set stops rotating, the position of the pull rod base 6 will not move randomly. The displacement of the pull rod base 6 is fixed, so the swing arm will not move, thereby realizing the locking of the swing arm position, and further ensuring the fixation of the sampling tube 30. The thread connection between the lead screw and the lead screw sleeve smoothly and stably drives the upward and downward movement of the sampling tube 30. If the swing arm position is locked, the stability is better and safer when the swing arm mechanism rotates and translates.

[0052] A sensor A11 for detecting the position of the pull rod base 6 is arranged on the swing arm base 4. Through the arrangement of the sensor A11, the position of the pull rod base 6 on the swing arm base 4 can be easily detected, especially when the pull rod base 6 moves to the limit position, so that the movement can be stopped in time to avoid damage to the parts.

[0053] The swing arm base 4 is rotatably arranged on the sliding base 13 through the rotary platform 12, the rotary platform 12 is provided with a gear ring A14, the swing arm base 4 is provided with a power element B15, the power element B15 can be a motor reducer set, drives the gear A16 engaged with the gear ring A14 to rotate, through the arrangement of the rotary platform 12, the stable rotation of the swing arm mechanism is realized.

[0054] Two sensors B17 for detecting the rotation position of the swing arm base 4 are arranged on the rotary platform 12 in the circumferential direction, through the arrangement of the sensor B17, the angle of the swing arm base 4 rotation is convenient to detect.

[0055] The walking mechanism includes a rail base 18, the rail base 18 is provided with a sliding rail B19, the sliding base 13 is provided with a sliding block B20 matched with the sliding rail B19, the rail base 18 is provided with a rack B21 in the same direction with the sliding rail B19, the sliding base 13 is provided with a power element C22, the power element C22 can be a motor reducer set, drives the gear B23 engaged with the rack B21 to rotate. The sliding base 13 is slidably connected with the rail base 18 through the sliding block B20 and the sliding rail B19, the sliding connection mode is simple and reliable.

[0056] The rail base 18 is provided with a sensor C24 for detecting the position of the sliding base 13 at both ends, through the arrangement of the sensor C24, the position of the sliding base 13 sliding on the rail base 18 can be detected, especially the limit position of the sliding base 13, the sensor C24 on the rail base 18 can detect the sliding base 13 in time to make it stop, avoiding derailing.

[0057] The bottom of the rail base 18 is provided with a stand column 25, through the arrangement of the stand column 25, the overall height of the rail base 18 is improved, so that the height of the swing arm mechanism sliding on the rail base 18 is increased to adapt to the transport vehicle 31 with high height.

[0058] The side of the rail base 18 is provided with a chain supporting groove 26 along the sliding direction of the sliding base 13, which is used for supporting the chain.

[0059] The sampling tube 30 is connected with the connecting rod 3 through the buffer mechanism, the buffer mechanism includes a buffer bottom plate 27 connected with the connecting rod 3, two buffer limiting plates 28 are arranged on the buffer bottom plate 27 in an up-down interval, buffer holes are vertically arranged on the two buffer limiting plates 28, the sampling tube 30 penetrates through the buffer holes, a spring 29 is sleeved on the sampling tube 30 between the two buffer limiting plates 28, the top end of the spring 29 abuts against the buffer limiting plate 28, and the bottom end of the spring 29 is connected with the sampling tube 30. Through the arrangement of the buffer mechanism, when the sampling tube 30 is lowered for sampling, the spring 29 can play a compression buffer role, so that the sampling tube 30 has a certain elastic stroke, which is beneficial to protect the sampling tube 30.

[0060] The swing arm mechanism allows the sampling tube 30 to move up and down. The upper swing arm 1, lower swing arm 2, connecting rod 3, and swing arm seat 4 form a parallelogram mechanism, ensuring that the angle of connecting rod 3 remains constant during the swing arm's vertical movement, thus guaranteeing that the sampling tube 30 remains vertical. The swing arm seat 4 is rotatably mounted on the sliding seat 13, allowing the swing arm mechanism to both rotate and translate, enabling sampling of the sampling tube 30 at any position in the horizontal plane. Furthermore, the track design increases the sampling machine's working range along its length, allowing for operations over longer distances. For example, sampling operations on large transport vehicles 31 no longer require movement of the transport vehicle 31, improving operational efficiency. Figure 10 The diagram shown is a schematic of the transport vehicle 31 parked on one side of the prototype.
