With the progress of technology, vehicles dedicated to highway inspection have emerged. They are equipped with advanced measuring instruments and data acquisition systems, and can efficiently and accurately complete various inspection tasks.

[0003] However, the existing special vehicles for highway inspection have certain limitations. In order to install large measuring equipment, some vehicles need to install additional structures on the roof, which not only increases the height of the vehicle, but may also affect the stability and passability of the vehicle. Especially when passing under low buildings or bridges, problems may occur. In addition, higher vehicles may also increase wind resistance, reduce fuel efficiency, and require more space for storage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a telescopic mechanism for the top of a special inspection vehicle that does not increase the vehicle height and wind resistance.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows: A telescopic mechanism for the top of a special inspection vehicle includes a top luggage rack, and also includes a horizontal telescopic track fixed on the top luggage rack and a laser box for inspection. When the horizontal telescopic track extends outward to the tail end to a predetermined working position, the laser box is detachably hung at the end of the telescopic end of the horizontal telescopic track through a connecting piece. This design mainly considers that the vehicle is not in the inspection state all the time. So when the vehicle is working, this device is in the extended state. At this time, the laser box can be hung at the end of the track, and it will not increase the overall height of the vehicle during work, greatly improving the safety and passing ability of the vehicle; when the vehicle is in the non-working state, this device is in the closed state. After the laser box is removed, the appearance of this vehicle is basically no different from that of an ordinary vehicle, and the top luggage rack can be used as an ordinary luggage rack to place luggage or be empty.

[0006] Furthermore, the horizontal telescopic track is mainly assembled and matched by a pair of telescopic slide rails that are radially constrained and axially slid relative to each other. A telescopic guide rail tie rod and a track limit tie rod are arranged between the telescopic ends of the pair of telescopic slide rails. A pair of limit devices for controlling the stroke of the track limit tie rod are arranged on the top luggage rack, and the telescopic guide rail tie rod is arranged outside the limit device; A positioning and locking structure is arranged between the outer sides of the telescopic ends of the pair of telescopic slide rails and the top luggage rack for fixing after the telescopic end extends to the predetermined working position.

[0007] Further, the telescopic slide rail mainly consists of a lower rail and an upper rail that slide axially. The bottom of the lower rail is fixedly connected to the top luggage rack, and the end of the upper rail is used to hang the laser box. A telescopic guide rail tie rod and a rail limit tie rod are provided between the two upper rails.

[0008] Further, the top luggage rack is composed of a top platform, a left guardrail, a right guardrail, and a top platform mounting bracket. The top platform mounting bracket is provided at the bottom of the top platform and is used to fixedly connect to the top of the vehicle. The left guardrail and the right guardrail are respectively erected on the left and right sides of the top platform, and the heights of the left guardrail and the right guardrail are higher than the horizontal telescopic track.

[0009] Further, a pair of laser boxes are hoisted by laser box mounting brackets at the ends of the upper rails that are extended to a predetermined work position.

[0010] The beneficial effects of the present utility model are as follows: This is a vehicle top telescopic mechanism specially designed and developed for highway inspection vehicles. This mechanism can be used for all inspection vehicle models involving highway facilities such as roads, bridges, and tunnels, can expand the vehicle models, expand the customer range, provide more professional special vehicles for the market, and meet the user needs.

The telescopic guide rail is combined with the conventional roof luggage rack and used in this system.

[0018] The mechanism of this system mainly consists of three parts. The first part is the fixed part of the roof luggage rack, the second part is the telescopic track part, and the third part is the laser box and bracket part.

[0019] The fixed part of the roof luggage rack. It is assembled by 1 - top platform, 2 - left guardrail, 18 - right guardrail, and 19 - top platform mounting bracket, mainly playing the role of fixing and installing various upper devices.

[0020] The telescopic track part. This part is installed on the top fixed luggage rack. The telescopic function is mainly assembled and coordinated by 3 - left lower track, 4 - left upper track, 16 - right lower track, and 14 - right upper track, mainly playing the role of extending and retracting. The stretching of this track is pushed and pulled by 9 - telescopic guide rail pull rod.

[0021] When the device is in the closed state, 17 - limit device 1 catches 5 - track limit rod, so that the track stroke is in the fully retracted state, and is locked in 20 - positioning hole 1 and 21 vacant hole 2 through 6 - track positioning pin 1 and 13 - track positioning pin 2.

[0022] When the device is in the working state and extends, 15 - limit device 2 catches 5 - track limit rod, so that the track stroke is in the fully open state, and is locked in 20 - positioning hole 1 and 21 vacant hole 2 through 12 - track positioning pin 3 and 7 - track positioning pin 4.

[0023] If 6 - track positioning pin 1, 13 - track positioning pin 2, 12 - track positioning pin 3, and 7 - track positioning pin 4 are all in the open state, the device slides between 17 - limit device 1 and 15 - limit device 2, locks 6 - track positioning pin 1 and 13 - track positioning pin 2, and the device is in the fully extended state.
