[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0028] like Figure 1-5 As shown, a pipeline detector comprises a winding frame 1, a cable 2 wound on the winding frame 1, a probe 3 arranged at one end of the cable 2, a lifting platform 4, a connecting rod mechanism 5, a telescopic mechanism 6 and a main unit 7. The top of the winding frame 1 is evenly distributed along its edge with four vertically upward sliding rods 11, wherein a lower transfer shaft 12 is connected between two sliding rods 11, and only four vertically downward sliding sleeves 41 are arranged along the edge of the bottom of the lifting platform 4, and the sliding sleeves 41 correspond to the sliding rods 11 one by one and are slidably connected with the corresponding sliding rods 11, wherein an upper transfer shaft 42 is connected between two sliding sleeves 41, and the upper transfer shaft 42 is connected between the two sliding sleeves 41. The connecting shaft 42 is located above the lower transfer shaft 12, the main machine 7 is placed on the top of the lifting platform 4, and the connecting rod mechanism 5 is located below the lifting platform 4. The connecting rod mechanism 5 includes an upper connecting rod 51, a lower connecting rod 52 and a pin 53. The top end of the upper connecting rod 51 is hinged to the bottom wall of the lifting platform 4, and the bottom end of the upper connecting rod 51 is hinged to the top end of the lower connecting rod 52 through the pin 53. The pin 53 is parallel to the upper transfer shaft 42, and the bottom end of the lower connecting rod 52 is rotatably sleeved on the lower transfer shaft 12. One end of the telescopic mechanism 6 is rotatably sleeved on the pin 53, and the other end of the telescopic mechanism 6 is rotatably sleeved on the upper transfer shaft 42.

[0029] Specifically, a junction box 8 is provided on one side of the winding rack 1, and the end of the cable 2 away from the probe 3 is detachably electrically connected to the host 7 through the junction box 8; the probe 3 is a steerable camera. When in use, the probe 3 can be extended into the pipeline through the cable 2, and the host 7 will obtain the image information collected by the probe 3 in real time, and can control the steering and lighting functions of the probe 3; the lower adapter shaft 12 is arranged between the two sliding rods 11 away from the cable 2, and the upper adapter shaft 42 and the lower adapter shaft 12 are arranged on the same side.

[0030] In one embodiment, the bottom of the main machine 7 can be detachably connected to the lifting platform 4 through a connecting component to improve the stability of the main machine 7 placed on the lifting platform 4 (not shown in the drawings).

[0031] In one embodiment, the telescopic component may be a cylinder or an electric push rod (not shown in the drawings).

[0032] In this embodiment, when in use, the user can directly place the main machine 7 on the top of the lifting platform 4 for use. When the horizontal height of the main machine 7 needs to be adjusted, the user can drive the telescopic mechanism 6 to shorten or lengthen. When the telescopic mechanism 6 shortens, the telescopic mechanism 6 will pull the pin shaft 53 to drive the upper connecting rod 51 and the lower connecting rod 52 to flip and unfold around the pin shaft 53, so that the lifting platform 4 is pushed by the swing of the upper connecting rod 51 and the lower connecting rod 52, so that the lifting platform 4 slides and rises along the sliding rod 11 through the sliding sleeve 41, and when the telescopic mechanism 6 is extended, the telescopic mechanism 6 The pin shaft 53 is pushed to drive the upper connecting rod 51 and the lower connecting rod 52 to flip and gather around the pin shaft 53, so that the lifting platform 4 is pulled by the swing of the upper connecting rod 51 and the lower connecting rod 52, so that the lifting platform 4 slides down along the sliding rod 11 through the sliding sleeve 41, and when the upper connecting rod 51 and the lower connecting rod 52 swing, the two ends of the telescopic mechanism 6 can swing adaptively around the corresponding upper connecting shaft 42 and the lower connecting shaft 12, thereby achieving the purpose of flexibly adjusting the placement height of the main machine 7, so as to adapt to the operating height required by different personnel and improve the user experience.

[0033] Furthermore, the telescopic mechanism 6 includes a threaded sleeve 61, an adapter sleeve 62 and a screw rod 63. One end of the threaded sleeve 61 is rotatably sleeved on the pin shaft 53, the adapter sleeve 62 is rotatably sleeved on the upper adapter shaft 42, the screw rod 63 is rotatably connected to one side of the rotating sleeve, the axis of the screw rod 63 is perpendicular to the axis of the adapter sleeve 62, and one end of the screw rod 63 is threadedly connected to the threaded sleeve 61.

[0034] In one embodiment, a knob may be coaxially disposed at one end of the screw rod 63 away from the threaded sleeve 61 , so that a user can control the rotation of the screw rod 63 through the knob (not shown in the drawings).

[0035] In this embodiment, when in use, the screw rod 63 can be rotated, and the thread can be used to drive the threaded sleeve 61 to slide along the screw rod 63, and the pin shaft 53 can be pushed or pulled by the threaded sleeve 61, thereby driving the upper connecting rod 51 and the lower connecting rod 52 to swing, so as to achieve the purpose of driving the lifting platform 4 to slide, lift or lower. At the same time, when the upper connecting rod 51 and the lower connecting rod 52 swing, the threaded sleeve 61 can swing adaptively, and the rotating sleeve can rotate adaptively to keep the threaded sleeve 61 and the screw rod 63 axially connected. When the screw rod 63 is stationary, due to the self-locking characteristics of the thread, the screw rod 63 and the threaded sleeve 61 will be relatively fixed, thereby limiting the movement of the upper connecting rod 51 and the lower connecting rod 52, and cooperating with the slide bar 11 to make the lifting platform 4 fixed and suspended, so as to place the main machine 7.

[0036] Furthermore, two connecting rod mechanisms 5 are provided, and the two connecting rod mechanisms 5 are distributed along the length direction of the lower transfer shaft 12 and are symmetrically arranged at the bottom of the lifting platform 4, and the two pin shafts 53 are coaxially connected, so that the telescopic mechanism 6 can synchronously drive the two groups of upper connecting rods 51 and lower connecting rods 52 to swing through the pin shafts 53, increase the force points at the bottom of the lifting platform 4, strengthen the support for the lifting platform 4, make the force on the lifting platform 4 more uniform, and improve the sliding stability of the lifting platform 4.

[0037] Furthermore, a support block 43 is fixedly provided on the bottom wall of the lifting platform 4. The vertical cross-section of the support block 43 is an inverted triangle, and the bottom end of the cross-section of the support block 43 deviates from the midpoint of its top edge in the horizontal direction and is offset toward the upper adapter shaft 42 to avoid the part of the winding frame 1 that reels in the cable 2. The connecting rod mechanism 5 is arranged close to the upper adapter shaft 42 to avoid interference with the connecting rod mechanism 5 by the structure of the winding frame 1 itself. The top surface of the support block 43 is connected to the lifting platform 4 to increase the force-bearing area of ​​the bottom of the lifting platform 4, so that the bottom wall of the lifting platform 4 is subjected to more uniform force during the swinging of the upper connecting rod 51 and the lower connecting rod 52, thereby improving the transmission stability between the connecting rod mechanism 5 and the lifting platform 4.

[0038] Furthermore, a reinforcing rod 13 is connected between the bottom ends of the two slide bars 11 on the same side of the cable 2 to improve the structural stability of the slide bar 11 through the reinforcing rod 13, prevent the slide bar 11 from being easily deformed, and extend the service life of the slide bar 11.

[0039] Furthermore, the side walls of the bottom end of the slide rod 11 are circumferentially provided with support ears 14, and the bottom end of the sliding sleeve 41 can abut against the top wall of the support ear 14, so as to support the sliding sleeve 41 through the support ear 14, provide additional supporting force for the lifting platform 4, reduce the burden of the connecting rod mechanism 5, and improve the load-bearing capacity of the lifting platform 4 in the retracted state.

[0040] Furthermore, one end of the screw rod 63 away from the threaded sleeve 61 is fixedly connected to a crank 64, so that the user can rotate the screw rod 63 through the crank 64, thereby reducing the difficulty of rotating the screw rod 63 and improving the operating experience.

[0041] Furthermore, a handle cover 65 is rotatably sleeved on the bent end of the crank 64. During the rotation of the crank 64, the handle cover 65 will rotate relative to the crank 64, thereby avoiding friction between the grip end of the crank 64 and the user's hand, thereby improving the smoothness and comfort of turning the crank 64.

[0042] Furthermore, a plurality of rollers 9 are evenly distributed on the bottom of the wire reel 1 , and a handrail 15 is provided on one side of the wire reel 1 , so that a user can push the wire reel 1 through the handrail 15 and move the wire reel 1 using the rollers 9 .
