Description

Technical Field

[0001] The utility model relates to the technical field of ground level vehicles, in particular to a ground level vehicle capable of preventing derailment. Background Art

[0002] In daily transportation, in order to move large machinery, it is often necessary to use a flat-bed truck for transportation. Some flat-bed trucks on the market do not have the function of preventing derailment. The local flat-bed truck is slightly faster, and the machinery carried by the flat-bed truck is heavy. A slight shake can easily lead to derailment. To solve this problem, we propose a flat-bed truck that can prevent derailment. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and proposes a derailment-proof horizontal vehicle.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a derailment-proof horizontal vehicle, comprising a track, wherein the bottom end of the vehicle body moves on the surface of the track with the help of wheels, an anti-derailment component is provided at the bottom of the vehicle body, and the vehicle body is supported between two tracks with the help of rollers in the anti-derailment component.

[0005] The effect achieved by the above components is that the vehicle body can move on the track with the help of wheels. When the vehicle body is about to derail, the rollers in the anti-derailment assembly are supported between the two tracks, thereby preventing the vehicle body from derailing.

[0006] Preferably, the anti-slip assembly includes a mounting seat fixed to the bottom end of the vehicle body, wherein a sleeve is detachably mounted on the surface of the mounting seat, wherein a sliding rod is slidably provided at the free end of the sleeve, the free end of the sliding rod is fixedly connected to a connecting arm, the port of the connecting arm is rotatably connected to a roller, a spring is provided between the connecting arm and the sleeve, and the spring is sleeved on the surface of the sliding rod.

[0007] The effect achieved by the above-mentioned components is: the elastic force of the spring is used to drive the connecting arm away from the sleeve, so that the roller at one end of the connecting arm is stuck in the groove on the side of the "I"-shaped track (or the side of the ordinary track), and a sliding path is given to the slide rod through the sleeve. The roller is pushed between the two tracks by using multiple slide rods located on the side of the mounting seat, which can play a certain role in preventing the vehicle body from derailing.

[0008] Preferably, the surface of the slide rod is movably sleeved with a screw sleeve, and the screw sleeve is threadedly inserted into the port of the sleeve, wherein one end of the spring contacts the screw sleeve and the other end contacts the connecting arm.

[0009] The effect achieved by the above components is: when the spring force needs to be adjusted, the screw sleeve can be turned to rotate on the sleeve port, thereby adjusting the spring compression amount and controlling the spring force.

[0010] Preferably, a piston is slidably connected inside the sleeve, and the sliding rod slides inside the sleeve with the help of the piston.

[0011] The effect achieved by the above components is that when the slide rod drives the piston to slide, the piston can be used to squeeze the air inside the sleeve, so that when the car body is about to derail, the elastic force of the spring and the damping of the compressed air can prevent the wheel from derailing.

[0012] Preferably, a lifting assembly is provided inside the mounting seat, and the lifting assembly includes a mounting groove opened at the bottom of the mounting seat, and a square groove is opened at the end of the mounting seat opposite to the mounting groove, a first bevel gear is rotatably connected inside the mounting groove, a shaft rod is rotatably inserted into the side wall of the mounting seat, and one end of the shaft rod located inside the mounting groove is fixedly connected to the second bevel gear, wherein the second bevel gear and the first bevel gear are meshed, and a screw rod is vertically threadedly inserted at the center of the first bevel gear, wherein the bottom end of the screw rod is fixedly connected to a slider, and the slider slides inside the square groove.

[0013] The effect achieved by the above components is: by rotating the rotating wheel outside the shaft rod, the shaft rod drives the second bevel gear to rotate, so that the first bevel gear rotates inside the mounting groove, and the first bevel gear rotates on the surface of the threaded screw rod, which makes the screw rod move downward, and the downward moving screw rod pushes the slider downward along the square groove. The slider and the square groove cooperate to prevent the threaded rod from rotating, and thus the vehicle body can be lifted when the vehicle body is unloaded.

[0014] Preferably, the screw rod and the mounting seat slide relative to each other.

[0015] Preferably, a bearing is installed on the top wall of the mounting groove, and a first bevel gear is fixedly connected to the bottom end of the bearing, and the first bevel gear is rotatably connected to the mounting groove by means of the bearing.

[0016] The effect achieved by the above components is that the first bevel gear is inseparable from the bearing and the mounting groove, but the two can rotate.

[0017] Compared with the prior art, the advantages and positive effects of the utility model are:

[0018] 1. In the utility model, the vehicle body can move on the track with the help of wheels. When the vehicle body is about to derail, the rollers in the anti-derailment assembly are supported between the two tracks, thereby preventing the vehicle body from derailing.

[0019] 2. In the utility model, the elastic force of the spring is used to drive the connecting arm away from the sleeve, so that the roller at one end of the connecting arm is stuck in the groove on the side of the "I"-shaped track (or the side of the ordinary track), and the sliding path is given to the slide rod through the sleeve. The roller is pushed between the two tracks by using multiple slide rods located on the side of the mounting seat, which can play a certain role in preventing the vehicle body from derailing.

[0020] 3. In the utility model, the shaft rod drives the second bevel gear to rotate by rotating the rotating wheel outside the shaft rod, so that the first bevel gear rotates inside the mounting groove. The first bevel gear rotates on the surface of the threaded screw rod, which makes the screw rod move downward. The downward moving screw rod pushes the slider downward along the square groove. The slider and the square groove cooperate to prevent the threaded rod from rotating, so that the vehicle body can be lifted up when the vehicle body is unloaded. BRIEF DESCRIPTION OF THE DRAWINGS
