Description

Technical Field

[0001] This utility model relates to the field of jack technology, specifically to a hydraulic jack support device. Background Technology

[0002] A jack is a small lifting device that uses a rigid lifting component as its working device to lift heavy objects within its stroke through a top support or bottom claw. Jacks are mainly used in factories, mines, transportation, and other sectors for vehicle repair and other lifting and supporting work. Existing jacks have a simple structure, and because the load will rotate slightly relative to the ground after being lifted, and because the load is too heavy, the jack is prone to tilting and collapse during use.

[0003] According to Chinese Patent Publication No. CN 115611190 A, a quick-change support device for a hydraulic support jack includes a movable component, a rotating component mounted on the movable component, a lifting component mounted on the rotating component, the lifting direction of the lifting component being parallel to the rotation axis of the rotating component, the rotating component driving the lifting component to rotate, a bracket mounted on the lifting component to support the jack, the lifting component driving the bracket to lift and lower, a support mechanism mounted on the movable component, the support mechanism including a bracket mounted on the movable component, a support frame mounted on the bracket, sliding rods slidably mounted on the support frame, the sliding rods having several grooves, a drive disc rotatably mounted on the bracket, the drive disc having a helical boss abutting against the grooves, the drive disc rotating causes the sliding rods to slide up and down, and the sliding rods moving down support the movable component. This technical solution solves the problems of inadequate support for mobile equipment and inconvenience in adjusting the installation angle of the jack in the prior art.

[0004] However, the aforementioned device may collapse due to uneven foundation, improper operation, uneven pressure, etc., causing the hydraulic support jack device to lose stability. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic jack support device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hydraulic jack support device, including a base plate, wherein a first groove is opened in the middle of the top of the base plate, and a fixing block is fixedly connected inside the first groove;

[0007] The top of the fixed block is provided with a jack shell, the bottom of which is fixedly connected to a jack body. The top of the jack body is fixedly connected to a lifting plate, and the top of the lifting plate is fixedly connected to an anti-slip pad. A vertical limiting cylinder is fixedly connected to the right side of the base plate. A guide slide is movably connected inside the vertical limiting cylinder. The number of vertical limiting cylinders is equal to the number of guide slides. The top of the guide slide is fixedly connected to the lifting plate. A hydraulic cylinder is fixedly connected to the top left side of the base plate.

[0008] Preferably, a support plate is fixedly connected to the right side of the hydraulic cylinder, and a column is fixedly connected to the top of the hydraulic cylinder.

[0009] Preferably, a support rod is fixedly connected to the bottom of the column, and a first cylindrical hole is opened at the bottom of the support rod.

[0010] Preferably, a second cylindrical hole is provided on the right side of the front of the support plate, and a nut is fixedly connected to the back of the second cylindrical hole.

[0011] Preferably, a bolt is movably connected inside the first cylindrical hole, and the surface of the bolt is connected to the internal thread of the nut.

[0012] Preferably, the bottom of the base plate is fixedly connected to a support column, and multiple support columns are provided.

[0013] Preferably, the bottom of the support column is fixedly connected to a chassis, and the number of chassis is equal to the number of support columns.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this utility model has a vertical limiting cylinder fixedly connected to the right side of the base plate. Inside the vertical limiting cylinder is a guide slide column. The vertical limiting cylinder limits the lifting range of the lifting plate. When the jack extends and pushes the lifting plate upwards, the vertical limiting cylinder ensures that the lifting plate will not exceed the predetermined lifting height, thus preventing the device from tipping over or being damaged due to excessive lifting. The vertical limiting cylinder helps ensure the safety and stability of the hydraulic support jack device during operation. The guide slide column is mainly used to guide the lifting movement of the lifting plate and ensure the accuracy and stability of its movement trajectory. During the process of the jack pushing the lifting plate upwards or downwards, the guide slide column slides inside the vertical limiting cylinder, thereby limiting the lateral movement of the lifting plate and ensuring that it can only lift and lower in the predetermined direction. The guide slide column helps reduce the swaying and deviation of the lifting plate during movement, improving the accuracy and reliability of the hydraulic support jack device. Furthermore, an anti-slip pad is fixedly connected to the top of the lifting plate. The anti-slip pad prevents slippage and protects against friction between the top of the lifting plate and the contact surface.

[0016] Secondly, this utility model has a column fixedly connected to the top of the hydraulic cylinder, which ensures the stability and safety of the hydraulic support in complex working environments. Then, a support column is fixedly connected to the bottom of the base plate, and a chassis is fixedly connected to the bottom of the support column. The support column can ensure that the device remains stable when subjected to pressure, avoiding tilting or collapse, and also maintaining overall stability. The chassis is usually fixedly connected to the support column to form an integral structure, which can ensure that the device maintains overall stability during operation and avoids loosening or falling off.

[0027] Through the above technical solution, a vertical limiting cylinder 8 is fixedly connected to the right side of the base plate 1. A guide slide 9 is movably connected inside the vertical limiting cylinder 8. The vertical limiting cylinder 8 limits the lifting range of the lifting plate 6. When the jack body 5 extends to push the lifting plate 6 upward, the vertical limiting cylinder 8 ensures that the lifting plate 6 will not exceed the predetermined lifting height, thereby preventing the device from tipping over or being damaged due to excessive lifting. The vertical limiting cylinder 8 helps ensure the safety and stability of the hydraulic support jack device during operation. The guide slide 9 is mainly used to guide the lifting of the lifting plate 6. The movement of the lifting plate 6 is ensured to be accurate and stable.

The guide slide column 9 helps to reduce the shaking and deviation of the lifting plate 6 during the movement, and improves the accuracy and reliability of the hydraulic support jack device. Then, the top of the lifting plate 6 is fixedly connected with an anti-slip pad 7, which can prevent slippage and protect the friction between the top of the lifting plate 6 and the contact surface.
