Description

Technical Field

[0001] The invention relates to the technical field of automobile maintenance, in particular to a hoist with an extended overall length for automobile maintenance. Background Art

[0002] Automobile maintenance refers to the technical inspection of a faulty automobile to find out the cause of the fault, take corresponding measures to eliminate the fault, and restore the performance and safety standards of the automobile. Automobile maintenance is usually divided into two types: major repairs and minor repairs. Major repairs involve repairing or replacing any parts of the automobile, including basic parts, to restore the good technical condition and life of the automobile; while minor repairs are to ensure or restore the working ability of the automobile by replacing or repairing individual parts. In the process of automobile maintenance, in order to be able to lift the automobile quickly and stably, and at the same time provide a stable and safe working space for maintenance personnel, the present invention proposes a hoist with an overall extended length for automobile maintenance.

[0003] According to the search, the Chinese patent document, announcement number: CN115159386A, discloses a hoist with an overall extended length for automobile maintenance, which connects four movable blocks by sliding at the four corners of the "H"-shaped box, controls the movement of the movable blocks by the activity of the rack in the telescopic groove, and then the distance of the maintenance platform in the lifting mechanism can be adjusted by the movement of the movable blocks to adapt to vehicles of different sizes. The vehicle is driven onto the hoist, so that the front wheels of the vehicle are located on one maintenance platform, and the rear wheels of the vehicle are located on another maintenance platform. The vehicle is lifted by using the wheels as support, so that there is no risk of falling during the lifting and maintenance stages after the lifting, and the vehicle beam will not be damaged. However, the maintenance platform area of ​​the device is small during actual use, and it is difficult for the staff to drive the vehicle to the platform conveniently. In addition, due to the presence of the fixed crossbar, it is not suitable for off-road vehicles and other models, which reduces the overall practicality; in addition, the two maintenance platforms of the device are separated, and the lifting is not synchronized, so there are certain safety hazards during operation, which reduces the overall safety. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides a hoist with an extended overall length for automobile maintenance, which has the advantages of convenient operation, high safety, and improved overall work efficiency, and solves the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lifting machine with an overall extended length for automobile maintenance, comprising a base, a slide rail is fixedly installed on the top surface of the base, a drive motor is fixedly installed on the left side of the slide rail, a first slide groove and a second slide groove are provided on the top surface of the slide rail, a first slider and a bidirectional screw rod are installed inside the first slide groove, a synchronous wheel is fixedly installed on the right end of the bidirectional screw rod, a belt is installed on the outer side of the synchronous wheel, a second slider is installed inside the second slide groove, a first support is fixedly installed on the top surface of the second slider, a support rod is installed inside the first support, a second support is installed on the end of the support rod away from the first support, a lifting plate is fixedly installed on the top surface of the second support, a third slide groove is provided inside the lifting plate, and an extension plate is slidably installed inside the third slide groove.

[0008] Preferably, the number of the slide rail, the first slide groove, the second slide groove, the first slider and the second slider is set to two, the two first sliders are respectively slidably installed inside the two first slide grooves, and the two second sliders are respectively slidably installed inside the two second slide grooves.

[0009] Through the above technical solution, when the two first sliders slide in the two first slide grooves respectively, and the two second sliders slide in the two second slide grooves respectively, the first slider and the second slider can drive the first support and support rod and other parts to move relative to each other, thereby driving the lifting plate and other parts to move in the vertical direction, and the first slide groove and the second slide groove can effectively limit the position of the first slider and the second slider, thereby improving the overall practicality and stability of the device.

[0010] Preferably, there are two bidirectional screw rods, and the output shaft of the drive motor is fixedly connected to the left end of one of the bidirectional screw rods, and the first slider and the second slider are both threadedly connected to the outer side surface of the bidirectional screw rod.

[0011] Through the above technical solution, when the drive motor is started, the output shaft of the drive motor can drive the bidirectional screw to rotate, and the bidirectional screw can then drive the first slider and the second slider to move relative to each other, thereby effectively raising or lowering the position of the lifting plate, thereby improving the overall practicality of the device.

[0012] Preferably, the number of the synchronous wheels and the number of the belts are both two, and the two belts are drivingly connected to the outer sides of the two synchronous wheels.

[0013] Through the above technical scheme, when the driving motor drives one of the bidirectional screws and the synchronous wheel to rotate, the synchronous wheel can then drive the other synchronous wheel and the bidirectional screw to rotate together through two belts, thereby simultaneously lifting or lowering the lifting plates on both sides, thereby improving the overall synchronization and stability of the device.

[0014] Preferably, the number of the first support, the support rod and the second support are all eight, and a first pin is installed inside the support rod.

[0015] Through the above technical solution, the eight first supports, support rods and second supports can effectively connect the slide rails, lifting plates and other parts into a whole to realize the lifting of the device, while the first pin shaft further enhances the overall stability of the device and ensures the normal operation of the device as a whole.

[0016] Preferably, the number of the lifting plates is two, the number of the third slide grooves and the number of the extension plates are four, and the inner side surfaces of the two lifting plates are fixedly connected with a stabilizing rod.

[0017] Through the above technical solution, the stabilizer bar can connect the two lifting plates into a whole, further enhancing the stability and synchronization of the device. In addition, when the extension plate slides inside the third slide groove, the overall length of the lifting plate can be effectively changed, so that it can be suitable for vehicles of different models and lengths, thereby improving the overall applicability of the device.

[0018] Preferably, a plurality of limiting through holes are provided inside the lifting plate and the extension plate, and a second pin shaft is inserted into the limiting through holes.

[0019] Through the above technical solution, when moving the extension plate, the second pin shaft is first taken out, and then the extension plate is moved to a suitable position and the second pin shaft is inserted into the inside of the limiting through hole. Therefore, the position of the extension plate in the third slide groove can be effectively limited and fixed, thereby improving the overall practicality and stability of the device.

[0020] Preferably, auxiliary slopes are installed on both the left and right sides of the base.

[0021] Through the above technical solution, the two auxiliary slopes can facilitate the driver to drive the vehicle to the top of the device and drive away safely and smoothly, reducing the bumpy feeling during driving, while also protecting the equipment from damage and increasing the service life of the device.

[0022] Compared with the prior art, the present invention provides a hoist with an extended overall length for automobile maintenance, which has the following beneficial effects:

[0023] 1. The present invention takes out the second pin shaft, moves the extension plate to a suitable position, and then inserts the second pin shaft into the inside of the limiting through hole, so as to effectively limit and fix the position of the extension plate in the third slide groove, and thus can be suitable for vehicles of different models and lengths. After that, the vehicle can drive to the top of the lifting plate through two auxiliary slopes, which is convenient for the driver to drive safely and smoothly, reduces the bumpy feeling during driving, and also protects the equipment from damage.

[0024] 2. The present invention starts the driving motor, and the output shaft of the driving motor can drive one of the bidirectional screws and the synchronous wheel to rotate. The synchronous wheel can then drive the other synchronous wheel and the bidirectional screw to rotate together through two belts. The bidirectional screw can then drive the first slider and the second slider to move relative to each other. The first slider and the second slider can both drive the first support and the support rod and other parts to move relative to each other, so the position of the lifting plate can be effectively lifted or lowered. The first slide groove and the second slide groove can effectively limit the position of the first slider and the second slider, and under the action of the synchronous wheel, the lifting plates on both sides can be lifted or lowered at the same time, thereby improving the overall synchronization and stability of the device.
