[0022] In an embodiment, as shown in Figures 1 to 6 a four-column lift device includes a four-column lift main body 10. The four-column lift main body 10 in this embodiment is basically the same as the existing well-known products, so it will not be described in detail. On the outer side walls of the front parts of the left beam and the right beam of the lift platform 20 of the four-column lift main body 10, connecting seats 30 are welded and fixed.

[0024] Furthermore, the connecting seat 30 includes a fixed bottom plate, and the inner side wall of the fixed bottom plate is welded and fixed on the outer side wall of the front part of the left beam or the right beam;

[0025] At the front and rear of the top surface of the fixed bottom plate, vertical fixing plates are fixed. An adjusting screw 31 extending in the front and rear directions is movably connected to the two vertical fixing plates through bearings. One end of the adjusting screw 31 extends out of the corresponding vertical fixing plate and is fixed with a rotating part 32. An adjusting block 33 is screwed on the adjusting screw 31. A sliding block 34 is fixed on one side wall of the adjusting block 33. On the top surface at the outer side of the fixed bottom plate, a side baffle is fixed. A guide rail extending in the front and rear directions is fixed on the inner side wall of the side baffle, and the guide rail is inserted into the sliding groove of the corresponding sliding block 34. A first infrared emitter 1 or a first infrared receiver 2 is fixed on the inner side wall of the adjusting block 33.

[0026] It can rotate the rotating part 32 manually to rotate the adjusting screw 31, so as to realize the forward and backward movement of the adjusting block 33, change the forward and backward positions of the first infrared emitter 1 or the first infrared receiver 2, and ensure that the infrared rays of the first infrared emitter 1 can irradiate the receiving end of the first infrared receiver 2;

[0027] Furthermore, on the outer side walls of the rear parts of the left beam and the right beam of the lifting platform 20, there are both fixed with laterally extending outer horizontal plates 21 that extend front and back. A second connecting seat 40 is installed on the outer horizontal plate 21. The structure of the second connecting seat 40 is the same as that of the connecting seat 30. A second infrared emitter 3 or a second infrared receiver 4 is fixed on the inner side wall of its adjusting block 33. It can also rotate the rotating part 32 at the second connecting seat 40 manually to change the forward and backward positions of the second infrared emitter 3 or the second infrared receiver 4, so as to ensure that the infrared rays of the second infrared emitter 3 can irradiate the receiving end of the second infrared receiver 4 and realize inductive use.

[0028] Furthermore, a plurality of positioning through holes 22 are formed on the top surface of the outer horizontal plate 21. All the positioning through holes 22 are divided into two groups corresponding left and right. Each group of positioning through holes 22 is formed in the outer horizontal plate 21 in a front-back arrangement. At least two elastic positioning columns 41 are fixed on the bottom surface of the fixed bottom plate of the second connecting seat 40, and the elastic positioning columns 41 are clamped in the corresponding positioning through holes 22. With this structure, the second connecting seat 40 can be pulled out from the corresponding position of the outer horizontal plate 21 and then inserted into the position at the front or the rear to realize position adjustment, so as to meet the maintenance use of vehicles of different lengths and sizes, that is, adjust according to vehicles with different front and rear wheel spacings. It can be inserted into the positioning through holes 22 of the outer horizontal plate 21 at the front, middle or rear as needed for fixation, so as to meet the detection use of the wheels of different types of vehicles, and the adjustment is convenient.

[0029] Furthermore, a clamping strip 50 that extends front and back is fixed on the outer side wall of the middle part of the right beam. The top surface of the outer side of the clamping strip 50 is formed with a bent edge 51 that bends upward. An extension strip 61 that extends downward is formed or fixed at the inner side of the bottom surface of the material placing box 60. The extension strip 61 is inserted into the slot formed between the bent edge 51 and the outer side wall of the middle part of the right beam. The bottom surface of the material placing box 60 is pressed against the top surface of the bent edge 51. One side of the bottom of the extension strip 61 close to the bent edge 51 is an inclined wall surface, so as to facilitate the insertion of the bottom of the extension strip 61 into the slot formed between the bent edge 51 and the outer side wall of the middle part of the right beam.

[0030] Furthermore, adjustment screw connection through holes extending left and right are formed in both the front and rear portions of the bent edge 51.

The steel ball of the ball head plunger 52 extends out of the inner end of the corresponding adjustment screw connection through hole and is embedded in the corresponding concave hole formed in the corresponding side wall of the extension bar 61. By using the ball head plunger 52, the firmness of the installation and fixation of the material discharge box 60 can be improved.

[0031] Furthermore, upper horizontal baffles 5 are fixedly arranged on the top surfaces of the side baffles of the connection seat 30 and the side baffles of the fixed bottom plate of the second connection seat 40. The adjustment screw 31 and the adjustment block 33 are both located directly below the corresponding upper horizontal baffle 5.

[0032] The upper horizontal baffle 5 thereabove can protect the adjustment block 33, the first infrared emitter 1, the first infrared receiver 2, the second infrared emitter 3 or the second infrared receiver 4 therebelow, making them not easily collided by other accessories or objects during maintenance, so as to ensure their normal use.

[0033] In this embodiment, the first infrared emitter 1, the first infrared receiver 2, the second infrared emitter 3 and the second infrared receiver 4 are all electrically connected to a control host installed externally through electric connection wires. The alarm set externally is electrically connected to the control host through an electric connection wire, and the control host is also electrically connected to a display screen;

[0034] When the first infrared receiver 2 and the second infrared receiver 4 can transmit the induction signals to the control host, the program installed in the control host can process the induction signals and can control the alarm to be turned on to generate a sound, thereby reminding the user that the vehicle has traveled in place and can stop running, which is very convenient. These components such as the control host are all conventional components and will not be elaborated here.

[0035] When this embodiment is in use, first drive the vehicle onto the top surfaces of the left beam and the right beam. It is necessary to ensure that the front wheels block the infrared rays of the first infrared emitter 1 from irradiating into the first infrared receiver 2, and at the same time, the rear wheels block the infrared rays of the second infrared emitter 3 from irradiating into the second infrared receiver 4, indicating that it has moved in place. At this time, the first infrared receiver 2 and the second infrared receiver 4 can transmit the induction signals to the control host, and the program installed in the control host can process the induction signals and can control the alarm to be turned on to generate a sound, thereby reminding the user that the vehicle has traveled in place and can stop running.

[0036] Subsequently, it can be lifted to the required position by the lifting platform 20 for maintenance operations.

[0037] Among them, during maintenance and repair, the extension bar 61 can be inserted into the slot formed between the bent edge 51 and the outer side wall of the middle part of the right beam, and the bottom surface of the material placing box 60 is pressed against the top surface of the bent edge 51, so that components such as tools to be used and bolts removed can be placed in the material placing box 60, which is convenient to take and not easy to lose, and is very convenient.

[0038] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model shall be considered to fall within the protection scope of the present utility model.
