DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with 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 of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0029] See also Figures 1 to 3 The present application provides a technical solution: a four-post trolley lift, comprising a lifting platform 1, two anti-slip pads 201 are bonded to the top of the lifting platform 1, a rectangular maintenance groove 202 is opened on the top of the lifting platform 1, an auxiliary support assembly 300 for auxiliary support of the inside of the maintenance groove 202 is installed on the outer side of the lifting platform 1, two bubble levels 4 are fixedly installed on the outer side of the lifting platform 1, and a lifting mechanism 500 for driving the lifting platform 1 to move up and down is installed on the outer side of the lifting platform 1; through the auxiliary support assembly 300 on the outer side of the lifting platform 1 and the cooperation between the bubble level 4 and the lifting mechanism 500, the auxiliary support structure can be positioned more conveniently, making the overall operation process very simple and convenient, and convenient for the operator to operate easily, and at the same time, it can also allow the operator to more intuitively observe the horizontality of the lifting platform to ensure the stability during the lifting process, so that the lifting work can be carried out stably and conveniently, thereby greatly improving the practicality of the four-post trolley lift.

[0030] It should be noted that four evenly distributed support columns 203 are fixed to the bottom of the lifting platform 1, and two inclined panels 204 are fixed to one side of the lifting platform 1 and are symmetrically distributed with the maintenance groove 202 as the center. The bottom of the support column 203 and the bottom of the inclined panel 204 are located on the same horizontal plane, so that when the support column 203 is in contact with the ground, the bottom of the inclined panel 204 is also in contact with the ground, which is convenient for the vehicle to go up and down, and the two bubble levels 4 are symmetrically distributed, which is convenient for the operator to check.

[0031] In this embodiment, the auxiliary support assembly 300 is a structure used to prevent the vehicle tire from falling into the maintenance groove 202.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, the auxiliary support assembly 300 includes a plurality of support frames 301 slidably connected to the inner side of the maintenance groove 202, a plurality of sliding blocks 302 fixed to the outer side of the support frame 301, two sliding cavities 303 opened in the lifting platform 1 and connected to the inner side of the maintenance groove 202, a plurality of symmetrical plates 304 fixed to the bottom of the support frame 301, a first oblique socket 305 opened on the outer side of the symmetrical plate 304, two limit blocks 306 fixed to the bottom of the lifting platform 1 and symmetrically distributed, a plurality of second oblique sockets 307 opened on the outer side of the limit blocks 306 and arranged at equal distances, a pin 308 inserted into the inner side of the first oblique socket 305, and a connecting rope 309 fixed between the end of the pin 308 and the bottom of the corresponding support frame 301.

[0033] It should be noted that there are seven support frames 301, and the top of the support frame 301 and the top of the lifting platform 1 are located on the same horizontal plane, so that the support frame 301 can shield and assist in supporting the interior of the maintenance groove 202, so that the vehicle tire that accidentally falls into the maintenance groove 202 can be supported by the support frame 301, thereby facilitating adjustment so that it can return to the top of the lifting platform 1, thereby increasing the fault tolerance of the operation.

[0034] At the same time, two symmetrically distributed sliding blocks 302 are fixed to the outside of each support frame 301, and the outside of the sliding block 302 is arc-shaped. The sliding block 302 is slidably connected to the inner side of the sliding cavity 303 on the same side, so that the sliding block 302 can slide on the inner side of the sliding cavity 303, and then the support frame 301 is supported by the sliding support between the two sliding blocks 302.

[0035] In addition, two symmetrical plates 304 are fixed to the bottom of each support frame 301 in a symmetrical distribution. The openings on the opposite sides of the two corresponding first oblique holes 305 are located above the openings on the other side. The opening direction of the second oblique hole 307 is the same as the opening direction of the first oblique hole 305 on the same side. The pin 308 can be inserted between the inner sides of the first oblique hole 305 and the second oblique hole 307. At this time, the opposite ends of the two corresponding pins 308 are located above the other ends. Therefore, under the action of gravity, the pin 308 will not detach from the inner side of the second oblique hole 307 without human intervention, which not only facilitates the operator to position the support frame 301, but also facilitates the operator to cancel the positioning of the support frame 301, thereby effectively improving the convenience of operation.

[0036] It should also be noted that the length of the connecting rope 309 allows the pin 308 to be detached from the inner side of the first oblique socket 305 and the second oblique socket 307, so that the connecting rope 309 can play a role in placing the pin 308 without affecting the normal operation of the pin 308.

[0037] In this embodiment, the lifting mechanism 500 is a structure for lifting or lowering a vehicle.

[0038] like Figure 1 and Figure 2 As shown, the lifting mechanism 500 includes four hollow columns 501 located outside the lifting platform 1, a hydraulic cylinder 502 fixedly installed inside the hollow columns 501, and a lifting plate 503 fixedly installed on the output shaft of the hydraulic cylinder 502.

[0039] It should be noted that a sliding hole for the corresponding lifting plate 503 to slide is opened on the side of the hollow column 501 close to the lifting platform 1, and the side of the lifting plate 503 close to the lifting platform 1 is fixedly connected to the outer side of the lifting platform 1, so that the hydraulic cylinder 502 can drive the lifting platform 1 to be raised and lowered and moved through the lifting plate 503.

[0040] It should also be noted that the four hydraulic cylinders 502 form a hydraulic jacking system, and the system is integrated with pressure sensors and flow control valves and is controlled by the same controller, so that the four hydraulic cylinders 502 can perform jacking or pressure relief work synchronously, and under the action of the pressure sensors and flow control valves, the jacking pressure and inlet and outlet flow of the four hydraulic cylinders 502 can be the same.

[0041] The working principle of the above embodiment is:

[0042] (1) When the vehicle is lifted for inspection and repair, the vehicle is moved to the top of the lifting platform 1 through the inclined plate 204, and the anti-skid pads 201 on both sides play a certain anti-skid role on the vehicle. The hydraulic cylinder 502 is started to push the lifting plate 503 to move, and the lifting platform 1 can be driven to lift the vehicle through the cooperation between the four lifting plates 503. The levelness of the lifting platform 1 can be monitored in real time through the bubble level 4, which is convenient for judging the overall lifting stability, so that the operator can stand at the bottom of the lifting platform 1 and inspect the bottom of the vehicle through the maintenance groove 202.

[0043] (2) When it is necessary to move the support frame 301 that is used to provide a certain shielding effect on the maintenance slot 202 to one side, pull out the latch 308 so that it no longer serves as a limit between the limit block 306 and the symmetrical plate 304, and then slide the support frame 301 so that it is located on one side of the maintenance slot 202, and move the latch 308 corresponding to the outermost support frame 301 so that it is plugged into the corresponding first oblique hole 305 and the inner side of the second oblique hole 307 to limit the position between the limit block 306 and the symmetrical plate 304. Under the effect of tilting, gravity is used to prevent the latch 308 from automatically disengaging under natural conditions, so that it can maintain a stable state, allowing the position of the outermost support frame 301 to remain fixed, thereby facilitating the operator to perform maintenance through the maintenance slot 202. When it is necessary to restore the position of the support frame 301 to assist the vehicle to move out, the above principle is reversed, and after the latch 308 is pulled out, each support frame 301 is moved to be evenly distributed on the inner side of the maintenance groove 202, and the limit is completed by the insertion of the latch 308, so that the support frame 301 can play the role of auxiliary support and limit on the inside of the maintenance groove 202 again, preventing the vehicle tire from falling into the inside of the maintenance groove 202 due to operational errors, so that the support frame 301 can play the role of auxiliary support for the tire, which is convenient for adjustment after the position deviates, and the hydraulic cylinder 502 is started to drive the lifting platform 1 to move downward, and the bottom of the support column 203 and the inclined panel 204 are in contact with the ground, and the vehicle is started to be moved out of the lifting platform 1 through the inclined panel 204.

[0044] Compared with the prior art, the four-post trolley lift, through the auxiliary support assembly 300 on the outside of the lifting platform 1 and the coordinated use of the bubble level 4 and the lifting mechanism 500, can more conveniently position the auxiliary support structure, making the overall operation process very simple and convenient, and convenient for the operator to operate easily, and at the same time allowing the operator to more intuitively observe the horizontality of the lifting platform to ensure stability during the lifting process, so that the lifting work can be carried out stably and conveniently, thereby greatly improving the practicality of the four-post trolley lift and solving the shortcomings of the existing four-post trolley lift in positioning the auxiliary support structure, which is very cumbersome and consumes a lot of labor.

[0045] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.
